How to make images change a little quicker?
|
<p>My code works just fine but for some reason when you click on the play button it takes a bit longer to switch over to the pause sign, and occasionally it takes a bit longer for the pause button to go to the play button. I also have one more question, when you click on the rain and beach icon there's a blue square border that I didn't remember putting, how do you remove it?
Thanks, Love2code</p>

Ember routes not loaded in order
|
<p>I'm having an issue where the <code>beforeModel</code> (or <code>afterModel</code>) on my route isn't called <em>after</em> the application controller has been setup. This is an issue because I need some data from the application controller.</p>
<p>In another route this works as I'd expect (that the application controller is loaded prior to the route). The only difference is the one that works is an <code>Ember.ArrayController</code> and the one that doesn't is a standard <code>Ember.Controller</code>. I'm using <code>beforeModel</code> even though there isn't a model simply because I'm trying to transition away from it if a condition isn't meet.</p>
<p>If I change my non-working controller to an <code>Ember.ArrayController</code> and put in a pointless <code>model</code> call in the router then it still doesn't work.</p>
<p>The only other difference I can think of is that the one that isn't working is a nested controller defined by just a <code>route</code> and the working one isn't nested and is defined by <code>resource</code>.</p>
<pre><code>Router.map(function() {
this.resource("wizard", function() {
this.resource("wizard/schools", {path: "/schools"}, function() {
this.route("new"); // This one doesn't work
});
});
...
this.resource("schools", { path: "/schools" }); // This one does work
});
</code></pre>
<p>Any idea how I can ensure the application route/controller is loaded prior to my route?</p>
<p>I'm trying to do something along the lines of:</p>
<pre><code>beforeModel: function() {
var customerAccountPromise = this.controllerFor('application').get('customerAccount');
var self = this;
return customerAccountPromise.then(function(customerAccount) {
return self.get('store').find('school').then(function(schools) {
if (customerAccount.get('schoolLimit') <= schools.get('length')){
self.transitionTo('school', schools.get('firstObject'));
}
});
});
},
</code></pre>
<p>I'm currently running:</p>
<pre><code>DEBUG: Ember : 1.8.1
DEBUG: Ember Data : 1.0.0-beta.12
DEBUG: Handlebars : 1.3.0
DEBUG: jQuery : 1.11.1
</code></pre>
<p><strong>Update:</strong> here is the code for the working route:</p>
<pre><code>import Ember from 'ember';
import AuthenticatedRoute from "./authenticated";
var SchoolsRoute = AuthenticatedRoute.extend({
model: function() {
return this.get('store').find('school');
},
afterModel: function(schools) {
Ember.Logger.log("SchoolsRoute - afterModel");
var customerAccountPromise = this.controllerFor('application').get('customerAccount');
var self = this;
return customerAccountPromise.then(function(customerAccount) {
if (customerAccount.get('schoolLimit') === 1){
self.transitionTo('school', schools.get('firstObject'));
}
});
},
});
</code></pre>
<p>export default SchoolsRoute;</p>
<p>The application controller is just aliasing the session controller.</p>
<pre><code>import Ember from 'ember';
var ApplicationController = Ember.Controller.extend({
needs: ['session'],
currentUser: Ember.computed.alias('controllers.session.currentUser'),
customerAccount: Ember.computed.alias('currentUser.customerAccount'),
...
});
export default ApplicationController;
</code></pre>
<p>The router for the application is pretty simple:</p>
<pre><code>import Ember from 'ember';
var ApplicationRoute = Ember.Route.extend({
setupController: function(controller, model) {
Ember.Logger.log("application setupController");
return this._super(controller, model);
},
...
});
export default ApplicationRoute;
</code></pre>
<p>The important part in <code>AuthenticatedRoute</code> is the <code>beforeModel</code>:</p>
<pre><code>beforeModel: function(transition) {
Ember.Logger.log("AuthenticatedRoute - beforeModel");
if (Ember.isEmpty(this.controllerFor('session').get('token'))) {
// set notification
return this.redirectToSignIn(transition);
}
},
</code></pre>
<p>There is no other "setting up" of the <code>SessionController</code>. It is simply called via the <code>controllerFor</code>. And on <code>init</code> it calls a <code>loadUser</code> method which immediately logs the message "SessionController - loadUser" and then does a <code>store.find</code> call and when that returns it logs a message about setting the user.</p>
<p>And the logs show that the application gets setup first:</p>
<pre><code>DEBUG: -------------------------------

<p>Here is the session controller:</p>
<pre><code>import Ember from 'ember';
var SessionController = Ember.Controller.extend({
// called by updateHeaders
loadUser: function() {
Ember.Logger.log("SessionController - loadUser");
if (this.get('isSignedIn') && !this.get('currentUser')){
var self = this;
this.store.find('user', { email: this.get('email') }).then(function(users) {
Ember.Logger.log("SessionController - set user");
self.set('currentUser', users.get('firstObject'));
});
}
},
// if email/token change, update the headers
updateHeaders: function() {
if (this.get('isSignedIn')){
Ember.$.ajaxSetup({
headers: {
'X-User-Email': this.get('email'),
'X-User-Token': this.get('token')
}
});
this.loadUser();
}
}.observes('email', 'token').on('init'),
hasEmail: Ember.computed.notEmpty('email'),
hasToken: Ember.computed.notEmpty('token'),
isSignedIn: Ember.computed.and('hasEmail', 'hasToken'),
});
export default SessionController;
</code></pre>
<hr>
<p>Based on Kingpin2k's suggestion I looked at the case of it being a race condition and that was the issue.</p>
<p>Therefore I changed my SessionController to a normal object and then injected it into the application route so that I could return the <code>loadUser</code> function as a promise in the <code>beforeModel</code>.</p>

SWIG, Box2D, and C#
|
<p>What should be simple has turned into a convoluted mess of ugliness. So here's the story. I downloaded the awesome Box2D, took out the important c++ files and added an interface for SWIG. I then proceeded to create the Swig wrapper by using a makefile</p>
<pre><code>CC=g++
CFLAGS=-c -Wall -fPIC -I../
LDFLAGS=-shared -o box.dll
SOURCES=<OMITTED>
OBJECTS=$(SOURCES:.cpp=.o)
EXECUTABLE=box2d.dll
all: $(SOURCES) $(EXECUTABLE)
$(EXECUTABLE): $(OBJECTS)
$(CC) $(LDFLAGS) $(OBJECTS) -o $@
.cpp.o:
$(CC) $(CFLAGS) $< -o $@
swig:
swig -csharp -c++ -outdir Wrapper Box2D.i
clean:
-rm Collision/*.o
-rm Collision/Shapes/*.o
-rm Common/*.o
-rm Dynamics/*.o
-rm Dynamics/Contacts/*.o
-rm Dynamics/Joints/*.o
-rm Rope/*.o
</code></pre>
<p>Pretty normal stuff, and it works fine (After fixing %includes and not #includes in the interface file). So I "make swig" in cygwin, no problems there (had to re-order includes so base classes came first). Then I loaded it up in VS.NET 2012, copying all the wrapper .cs files into the solution and moving the DLL over. This is where it gets nasty.</p>
<p>First time round, I believe it was mixed x86 and x64 that was causing great issue. I could instantly see that this was the problem and was in no way confused by the highly descriptive error message:</p>
<pre><code>System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
</code></pre>
<p>In my attempts to fix this, much of the Googling resolved that perhaps the calling convention was the culprate, so I changed the SWIG wrapper cpp file to export the functions into the dll as __cdecl rather than __stdcall, and updated the wrapper appropriately.</p>
<p>Anyway so I eventually fixed the x86/x64 mixing by making a new x86 build profile, and then upon calling any function in the dll, the program just hanged. So I decided to revert back to basics and simply compile with __stdcall, no wrapper mods, and just see if it would work. </p>
<p>It didn't. </p>
<p>Now it complains that it's missing entry points:</p>
<pre><code>{"Unable to find an entry point named 'SWIGRegisterExceptionCallbacks_box2d' in DLL 'box2d'.":""} System.Exception {System.EntryPointNotFoundException}
</code></pre>
<p>Upon dumping the exports of the DLL, the functions are correctly mangled according to __stdcall</p>
<pre><code>CSharp_b2_aabbMultiplier_get@0
...
SWIGRegisterStringCallback_box2d@4
SWIGRegisterExceptionCallbacks_box2d@44
</code></pre>
<p>etc. etc.</p>
<p>Now the C# wrapper end doesn't seem to find this a problem and goes straight ahead and ignores the mangling</p>
<pre><code>[DllImport("box2d", EntryPoint="SWIGRegisterExceptionArgumentCallbacks_box2d")]
</code></pre>
<p>So I tried this out of desperation</p>
<pre><code>[DllImport("box2d", EntryPoint = "SWIGRegisterExceptionCallbacks_box2d", CallingConvention = CallingConvention.StdCall)]
</code></pre>
<p>Which was met with the same problem. The solution? Stick the mangled name in.</p>
<pre><code>[DllImport("box2d", EntryPoint="SWIGRegisterExceptionArgumentCallbacks_box2d@44")]
</code></pre>
<p>... for all 1392 DllImport attributes. Not a solution. </p>
<p>I've tried compiling DLLs with both minGW and Cygwin, so I doubt that the way the DLLs are compiled is much of an issue.</p>
<p>Does anybody have any idea what I'm doing wrong?</p>

Using malloc and free in recursive file scanning function
|
<p>I am writing a function that takes in a file-path argument and scans through the directory structure and loads it into a tree. I'm using a recursive function I created called <code>scan_and_add_children(struct Node* root)</code> that takes in the root node. The idea is I loop through the files in a directory, add the current node to the tree, and, if it's a directory, I call my recursive function using the current node as the root to add all of that directories children as well. However, I keep getting a <code>malloc(): corrupted top size</code> error. I am wondering if the dynamically allocated memory in the <code>new_node_to_be_added</code> variable is being lost once I make my recursive call. I can't free the node before the call as it's being used in my recursive function. I am yet to add my function that free()'s the tree, however, I know this is not the issue as I set a break point at the end of main and my program breaks before it even gets out of the function. I'm not super experienced with dynamic memory managenemt so I am trying to use this exercise to get more practice. Can someone explain to me what's going wrong?</p>
<p>Here's my main program:</p>
<pre><code>#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <dirent.h>
#include <sys/stat.h>
#include <string.h>
#include "linkedlist.h"
void scan_and_add_children(struct Node*);
int file_exists(char* path);
struct List* create_list(int level);
struct Node* create_node(int level, char* name);
int main(int argc, char** argv) {
if(argc != 2) {

Create calculated field based on previous rows Oracle SQL
|
<p>I am trying to create a manually calculated column where I keep track of a current inventory.</p>
<p>Currently, I have a table that looks like this:</p>
<pre><code>| Group | Part | Operation Type | Transaction Amount |
|--------------|------|----------------|--------------------|
| Concrete | A | STOCK | 100 |
| Concrete | A | Buy | 25 |
| Concrete | A | Make | -10 |
| Concrete | A | Make | -10 |
| Concrete | A | Make | -10 |
| Concrete | A | Make | -10 |
| Concrete | A | Make | -10 |
| Concrete | B | STOCK | -10 |
| Concrete | B | Make | -10 |
| Concrete | B | Make | -10 |
| Concrete | B | Make | -10 |
| Concrete | B | Make | -10 |
| Concrete | B | Make | 150 |
| Construction | C | STOCK | 10 |
| Construction | C | Make | -1 |
| Construction | C | Make | -1 |
| Construction | C | Make | -1 |
| Construction | C | Make | -1 |
| Construction | D | STOCK | 5 |
| Construction | D | Make | -5 |
</code></pre>
<p>The table is first ordered by <code>group</code> then by <code>part</code>, and then <code>STOCK</code> is always shown as the first value. The idea is to create a new manually calculated column, <code>curr_inventory</code>, that allows for us to keep track of current inventory and see if or when our inventory for a given part, for a given group, dips below 0.</p>
<p>Ideally, the end results would look like this:</p>
<pre><code>| Group | Part | Operation Type | Transaction Amount | New_Inventory_Column |
|:------------:|:----:|:--------------:|:------------------:|:--------------------:|
| Concrete | A | STOCK | 100 | 100 |
| Concrete | A | Buy | 25 | 125 |
| Concrete | A | Make | -10 | 115 |
| Concrete | A | Make | -10 | 105 |
| Concrete | A | Make | -10 | 95 |
| Concrete | A | Make | -10 | 85 |
| Concrete | A | Make | -10 | 75 |
| Concrete | B | STOCK | 10 | 10 |
| Concrete | B | Make | -10 | 0 |
| Concrete | B | Make | -10 | -10 |
| Concrete | B | Make | -10 | -20 |
| Concrete | B | Make | -10 | -30 |
| Concrete | B | Make | 150 | 120 |
| Construction | C | STOCK | 10 | 10 |
| Construction | C | Make | -1 | 9 |
| Construction | C | Make | -1 | 8 |
| Construction | C | Make | -1 | 7 |
| Construction | C | Make | -1 | 6 |
| Construction | D | STOCK | 5 | 5 |
| Construction | D | Make | -5 | 0 |
</code></pre>
<p>The end result would be a column that initiates when the part number has changed and the operation type is STOCK, and then begins to calculate (using the transaction amount) what the current inventory is.
I am not sure where to start on a SQL query that would allow for this. Intuitively, the pseudocode would look something like:</p>
<pre><code>for each row in table:
if operation_type == "stock":
curr_inv = stock.value
else:
curr_inv = previous_curr_inv + transaction_amount
</code></pre>
<p>However, I am not sure how to even begin writing SQL for this. I typically try to post what SQL I am working with but I don't even know where to begin. I have looked at various posts online, on SO, including posts <a href="https://stackoverflow.com/questions/37517940/sql-calculated-field-base-on-calculated-field">like this</a>, <a href="https://stackoverflow.com/questions/53268337/create-calculated-value-based-on-calculated-value-inside-previous-row">and this</a>, <a href="https://stackoverflow.com/questions/37776958/oracle-sql-calculate-value-using-previous-row">and this</a>, but I could not see how the selected answers could be used as a solution.</p>

<p>This is the data in one row. And such I have from row 22-78. the final files have a similar number of columns but many more rows.
I am not sure what would be a good way to organize this into a single column in excel </p>
<p>I got this working for 1 row.
here's the code </p>
<pre><code>Sub RowsToColumn()

Cells(r, 1) = RI
RI.Clear
Next RI
Next RN
Columns("A:A").SpecialCells(xlCellTypeBlanks).Delete Shift:=xlUp

I need some help increasing the height of HTML canvas lines
|
<p>I am doing a project where the user selects what programming language they enjoy out of a radio box. It sets an object to the Local Storage and creates a bar graph and the bars go up depending on what choice the select. I'm having trouble though where if the user selects the language for the third time, it turns out what is in the image. I change the height each time and for some reason it also goes over the axis. I just want the height to change. I'm not super familiar with the canvas. Is there a way I could go about doing this? I just simply want the bar to start at the origin and go up, but not down.
Code below:</p>

how to customize remote validation like a normal jquery ajax?
|
<p>Is there a way we can customize remote validation like a normal jquery ajax?</p>
<pre><code>$('#banner').bootstrapValidator({
framework: 'bootstrap',
fields: {
bannerType: {
icon: false,
validators: {
notEmpty: {
message: 'Banner type is required'
}
}
},
bannerTitle: {
icon: false,
validators: {
notEmpty: {
message: 'Banner title is required'
}
}
},
bfromDate: {
verbose: true,
validators: {
notEmpty: {
message: 'From date is required'
},
date: {
format: 'MM/DD/YYYY',
message: 'The value is not a valid date'
},
remote: {
url: '/assets/cfc/exchange/exchangeintra.cfc?method=checkAvailabilityofDates',
type: 'POST',
dataType:'json',
data: function(validator, $field, value) {
return {
selectedDate: validator.getFieldElements('bfromDate').val(),
bannerId: validator.getFieldElements('bannerId').val(),
};
},
}
}
},
btoDate: {
verbose: true,
validators: {
notEmpty: {
message: 'To date is required'
},
date: {
format: 'MM/DD/YYYY',
message: 'The value is not a valid date'
},
remote: {
url: '/assets/cfc/exchange/exchangeintra.cfc?method=checkAvailabilityofDates',
type: 'POST',
dataType:'json',
data: function(validator, $field, value) {
return {
selectedDate: validator.getFieldElements('btoDate').val(),
bannerId: validator.getFieldElements('bannerId').val(),
};
},
}
}
},
authorImage: {
validators: {
notEmpty: {
message: 'Banner image is required'
},
file: {
extension: 'jpeg,jpg,png',
type: 'image/jpeg,image/png',
message: 'The selected file is not valid'
}
}
},
bannerLink: {
icon: false,
validators: {
notEmpty: {
message: 'Banner link is required'
}
}
}
}
});
</code></pre>
<p>When remote validation success than do any other things,if failed than do another things.</p>
<p>I have got the following link: <a href="http://formvalidation.io/examples/using-data-returned-validator/" rel="nofollow">http://formvalidation.io/examples/using-data-returned-validator/</a></p>
<p>But it is work,only if i am using formvalidation but here i am using bootstrapValidator.so is there any way to do the same like formvalidation.</p>

jQuery client side password verification
|
<p>first of all I'd like to say <strong>I realise</strong> it's not a secure method.
This is only for training purpose.</p>
<p>The algorhitm should be:</p>
<ol>
<li>click on a div with id="login-bg"</li>
<li>app displays the banner</li>
<li>provide the code</li>
<li>if the code's ok set cookie and fade out the banner</li>
<li>if the code's not ok the div shakes (still remaining on the screen)</li>
<li>if you don't want to provide the code press 'cancel' and fade out the banner</li>
</ol>
<p>Set cookie function (it works fine):</p>
<pre><code><?php
if(!isset($_COOKIE['is_logged']))
{ ?>
<script type="text/javascript">
function SetPwd(c_name,value,expiredays){
var exdate=new Date()
exdate.setDate(exdate.getDate()+expiredays)
document.cookie=c_name+ "=" +escape(value)+";path=/"+ ((expiredays==null) ? "" : ";expires="+exdate.toGMTString())
}
</script>
<?php } ?>
</code></pre>
<p><strong>And here must be the problem with jQuery:</strong></p>
<pre><code><?php
if(!isset($_COOKIE['is_logged']))
{ ?>
<div id="login-bg">
<div class="content">
<h2>Provide the code!</h2>
<form id="check-form" method="post" action="">
<input type="password" name="code" placeholder="code" id="code" />
<input type="submit" value="Submit" id="enjoy"/>
</form>
<h3>And enjoy free access!</h3>
<a id="cancel">Cancel</a>
</div>
</div>
<script type="text/javascript">
$(document).ready(function() {
if( document.cookie.indexOf("is_logged") ===-1 ){
$('#video').click(function(){
$("#login-bg").fadeIn('slow');
});
$('#cancel').click(function(){
$('#login-bg').fadeOut('slow');
//window.location = "<?php echo $this->baseUrl; ?>/index";
});
}
$("#submit").click(function (){
var value = $('#code').val();
var pass = 'test';
if( value == test ){
SetCookie('is_logged','is_logged',365*10)
$("#login-bg").remove();
}
else {
$('#login-bg').effect( "shake" );
}
});
});
</script>
<?php } ?>
</code></pre>
<p>In my opinion the value '#code' id not passed to jQuery from the form.<br>
But I may be wrong.</p>
<p>Do you have any ideas. Could you make it work?<br>
Thanks for your help.</p>

Use neural netword to fit a reduced boolean function, but found the super-params not as expected
|
<p>This is the boolean function I try to fit.
[boolean function description][1]</p>
<p>Theoretically we need a neural network with 1 hidden layer which has 3 neurons at least.<br />
And that's actually how I built the neural network in Pytorch.<br />
However, despite the prediction of NN usually correct, the parameters (I mean the weights and bias) not as expected.<br />
I expect the parameters to be like this way(A perceptron operation is equivalent to a Boolean gate):<br />
[perceptron equivalent to a boolean gate][2]</p>
<p>Here the key code:</p>
<pre><code>class NeuralNetwork(nn.Module):
def __init__(self):
super(NeuralNetwork, self).__init__()
self.linear_relu_stack = nn.Sequential(
nn.Linear(4, 3),
nn.ReLU(),
nn.Linear(3, 1),
)
def forward(self, x):
logits = self.linear_relu_stack(x)
return logits
base_lr = 0.001
optimizer = torch.optim.Adam(model.parameters(), base_lr)
criterion = nn.MSELoss().to(device)
</code></pre>
<p>Here is the key output:</p>
<p>First, the prediction not so bad, The categories are correct, but some of the numbers are not precise enough</p>
<pre><code> w x y z pred
0 0 0 0 0 [tensor(0.9992, grad_fn=<UnbindBackward0>)]
1 0 0 0 1 [tensor(0.2459, grad_fn=<UnbindBackward0>)]
2 0 0 1 0 [tensor(0.9992, grad_fn=<UnbindBackward0>)]
3 0 0 1 1 [tensor(0.0040, grad_fn=<UnbindBackward0>)]
4 0 1 0 0 [tensor(0.9992, grad_fn=<UnbindBackward0>)]
5 0 1 0 1 [tensor(0.7707, grad_fn=<UnbindBackward0>)]
6 0 1 1 0 [tensor(-0.0015, grad_fn=<UnbindBackward0>)]
7 0 1 1 1 [tensor(-0.0025, grad_fn=<UnbindBackward0>)]
8 1 0 0 0 [tensor(0.9992, grad_fn=<UnbindBackward0>)]
9 1 0 0 1 [tensor(-0.2525, grad_fn=<UnbindBackward0>)]
10 1 0 1 0 [tensor(0.9992, grad_fn=<UnbindBackward0>)]
11 1 0 1 1 [tensor(-0.0077, grad_fn=<UnbindBackward0>)]
12 1 1 0 0 [tensor(0.9992, grad_fn=<UnbindBackward0>)]
13 1 1 0 1 [tensor(0.2722, grad_fn=<UnbindBackward0>)]
14 1 1 1 0 [tensor(-0.0066, grad_fn=<UnbindBackward0>)]
15 1 1 1 1 [tensor(0.0033, grad_fn=<UnbindBackward0>)]
</code></pre>
<p>Second, the parameters are not as expected.</p>
<pre><code> linear_relu_stack.0.weight tensor([[-0.3637, 0.3838, 0.7624, 0.3661],
[ 0.2857, 0.5719, 0.5721, -0.5846],
[ 0.4782, -0.5035, -0.2349, 1.2070]])
linear_relu_stack.0.bias tensor([-0.7657, -0.8599, -0.4842])
linear_relu_stack.2.weight tensor([[-1.3418, -1.7255, -1.0422]])
linear_relu_stack.2.bias tensor([0.9992])
</code></pre>
<p>My question is why the NN doesn't convege to my expected position?<br />
What' the problem?

Issues Parsing Multi Nested Childs in XML using lxml
|
<p>Im having issues parsing out each child node within an xml file. The number of nodes can change per Instrument_Root. For instance, Instrument_Watch is NULL here, but will be populated in other instances after this. My goal is to have each child node parsed individually (Instrument_Ratings, Instrument_Attribute_Ratings, Instrument_Organization, Instrument_Supports, etc.)</p>
<p>I tried doing the following, but it just returned the first intance repeatedly - there are 3700 Instrument_Root in the file, and Instrument_Rating for this one Instrument_Root was repeated 3700 times. I also ran into errors with etree due to the namespace. </p>
<pre><code>from lxml import objectify
xml = objectify.parse(file)
root = xml.getroot()
tree1 = []
tree2 = []
tree3 = []
tree4 = []
for children in range(len(root.getchildren())):
tree1.append([child.text for child in root.getchildren()[children].iterchildren()])
for children2 in root.Instrument_Root.Instrument_Ratings.Instrument_Rating.getchildren():
tree2.append([child2.text for child2 in root.Instrument_Root.Instrument_Ratings.Instrument_Rating.getchildren()])
for children3 in root.Instrument_Root.Instrument_Ratings.Instrument_Rating.Instrument_Rating_Attributes.Instrument_Rating_Attribute.getchildren():
tree3.append([child3.text for child3 in root.Instrument_Root.Instrument_Ratings.Instrument_Rating.Instrument_Rating_Attributes.Instrument_Rating_Attribute.getchildren()])

Unable to correcty call a void function in Java to output to the console

<p>I have the following class written in the Employee.java script:</p>
<pre><code>public class Employee {

// Description:
// Program creates an Employee class that includes three (3) private instances:
// 1) first name (String)
// 2) last name (String)
// 3) monthly salary (double)
// Program provides:
// a) a constructor that initializes instance variables
// b) set and get methods for each instance variable
// c) test app named EmployeeTest that demonstrates Employee class capabilities
// d) two (2) Employee objs, from which obj's yearly salary is displayed

System.out.println("Program: Three \n");
}
}
</code></pre>
<p>With the corresponding test class written in a separate script called EmployeeTest.java:</p>
<pre><code>public class EmployeeTest {
public static void main(String[] args) {
**developerInfo();**
Employee employee1 = new Employee("John", "Doe", 2875.00);
Employee employee2 = new Employee("Jane", "Doe", 3150.00);
System.out.printf("%s %n", "Before 20% raise:");
System.out.printf( "Employee 1: %s %s; Yearly Salary: $%.2f\n",
employee1.getFirstName(), employee1.getLastName(),
12 * employee1.getMonthlySalary() );
System.out.printf( "Employee 2: %s %s; Yearly Salary: $%.2f\n",
employee2.getFirstName(), employee2.getLastName(),
12 * employee2.getMonthlySalary() );
employee1.setMonthlySalary(employee1.getMonthlySalary() * 1.2);
employee2.setMonthlySalary(employee2.getMonthlySalary() * 1.2);
System.out.printf("%s %n", "After 20% raise:");
System.out.printf( "Employee 1: %s %s; Yearly Salary: $%.2f\n",
employee1.getFirstName(), employee1.getLastName(),
12 * employee1.getMonthlySalary() );
System.out.printf( "Employee 2: %s %s; Yearly Salary: $%.2f\n",
employee2.getFirstName(), employee2.getLastName(),
12 * employee2.getMonthlySalary() );
}
}
</code></pre>
<p>I cannot figure out how to call the developerInfo function in order get that to print to the console. Expected output is:</p>
<pre><code>Name: Erin
Course: Object-Oriented Programming
Program: Three
Before 20% raise:
Employee 1: John Doe; Yearly Salary: $34500.00
Employee 2: Jane Doe; Yearly Salary: $37800.00
After 20% raise:
Employee 1: John Doe; Yearly Salary: $41400.00
Employee 2: Jane Doe; Yearly Salary: $45360.00
</code></pre>
<p>Any insight would be so appreciated! Thank you!</p>

options.chunkedMode = false;
var params = {};

options.params = params;
options.headers = {
Connection: "close"

Integrating Facebook Audience Network in Xamarin
|
<p>I have been trying to integrate Facebook Audience Network so as to load native ads in my Xamarin Native iOS application. When I debug my application the code enters method "NativeAdDidFail" and the NSError says "No fill" and No other information is printed in the console.</p>
<p>This is what I have done:</p>
<ol>
<li>Created a resource in business manager and Selected iOS as the target platform.</li>
<li>I left out the payment/mediation and app store URL since my app is not published.</li>
<li>Added an ad placement for native ads and Added one test device in the Monetization manager by adding my iphones IDFA.</li>
<li>Enabled testing, Checked the checkbox for "use real ads", I also clicked on the "choose ad type" <strong>but it doesnt seem to be saved?</strong></li>
<li>Added one test user in business manager and Assigned access to the created property.</li>
<li>Downloaded native Facebook app and Enabled tracking in the background for the native facebook app.</li>
<li>Logged in on the native app with the email of the test user that I added.</li>
<li>Added "SkadNetworkIdentifier" and LSApplicationQueriesSchemes in info.plist-> v9wttpbfk9.skadnetwork & n38lu8286q.skadnetwork</li>
<li>Downloaded Xamarin.Facebook.Audiencenetwork.ios</li>
</ol>
<p><strong>This is my code:</strong></p>
<pre><code> AdSettings.SetAdvertiserTrackingEnabled(false);
AdSettings.ClearTestDevices();
AdSettings.AddTestDevice("74312C38-4958-4187-B385-9FCFE68FRRA9");
nativeAd = new NativeAd("CAROUSEL_IMG_SQUARE_LINK#611875720420055_511995483752412")
{ Delegate = this };
nativeAd.LoadAd();

How to use Session to save value on current row of GridView, to be copied into TextBox? - VB.Net
|
<p>I'm trying to use <code>Session</code> to record the data of the 1st column of current row to be used in another Web From which will be opened using a <code>LinkButton</code> that is in the <code>GridView</code>.</p>
<p>Basically, if I click the <code>LinkButton</code> on the 1st row, the 1st column data of the 1st row will be copied to the next Web Form. But before I do that, I want to do a smaller scale experiment to test it. So instead for now I want the <code>Session</code> to copy the data into a <code>TextBox</code> in the same form.</p>
<p>For reference, here is the design of the <code>GridView</code>, most rows removed since they're not relevant:</p>
<pre><code><asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" Font-Names="Arial">
<AlternatingRowStyle BackColor="#B7DBFF" />
<Columns>
<asp:BoundField DataField="caseticket" HeaderText="Ticket #" >
<HeaderStyle BackColor="#000066" ForeColor="White" Wrap="False" width="10%"/>
<ItemStyle Wrap="False" />
</asp:BoundField>
<asp:TemplateField ShowHeader="False">
<HeaderStyle BackColor="#000066" ForeColor="White" Wrap="False" width="10%"/>
<ItemTemplate>
<asp:linkbutton ID="newLog" runat="server" onclick = "CaseLog_click" >Add Log </asp:linkbutton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<HeaderStyle BackColor="#000066" />
<RowStyle HorizontalAlign="Center" />
</asp:GridView>
</code></pre>
<p>For the <code>TemplateField</code> is a <code>LinkButton</code> with a <code>onclick</code> property. With it, I created the sub:</p>
<pre><code>Sub CaseLog_click(ByVal sender As Object, ByVal e As EventArgs)
Session("ticket") = GridView1.SelectedRow.Cells(1).Text
'Response.Redirect("~/CaseLog.aspx") ==> will be using this to proceed to next Web Form
TextBox1.Text = Session("ticket") '==> For test use only.
End Sub
</code></pre>
<p>If I only kept the <code>Response.Redirect("~/CaseLog.aspx")</code> in the sub, the <code>LinkButton</code> can direct me to the next Web Form. But as it is now, during testing when I use the <code>LinkButton</code> I get an error on the <code>session</code> line of the sub.</p>
<p><code>Object reference not set to an instance of an object.</code></p>
<p>Is the code salvageable, or do I need to redo this?</p>
<p>Thanks.</p>

R-Shinny image path not working when multiple folders
|
<p>I have an R-Shinny app which displays images based on two <code>selectInput</code> as follows:</p>
<pre><code>ui<-dashboardBody(
tabItem(tabName = "title",
fluidRow(
column(6,
box(
background = "olive", width = NULL,
column(6,
selectInput("SpIDA",
"Species:",
choices = c("SELECT SPECIE",dat$Specie),
selected = "SELECT SPECIE")),
column(6,
selectInput("SpArea",
"Area:",
choices = c("SELECT AREA",dat$Area),
selected = "SELECT AREA"))
))
),
tabsetPanel(
tabPanel("title",
fluidRow(column(width = 6,
imageOutput("img.1", height = "50%")
))
))
)
)
</code></pre>
<p>I have the images stored in a local directory as "www/Specie/Area", and the image names are standard across the folders. My problem, is that when more than two areas are available for a particular specie, the images are not displayed...</p>
<p>My server section is:</p>
<pre><code>server <- function(input, output, session) {
observe({
tmp<-dat[dat$Specie == input$SpIDA,]
updateSelectInput(session,
"SpArea",
"Area:",
choices = c("SELECT AREA",tmp$Area),
selected = "SELECT AREA")
}) #Just to filter the selection SPArea selection choices based on the SpIDA
output$img.1 <- renderImage({
image_path<-file.path("www",input$SpIDA,input$SpArea,
"img1.png")
return(list(src = image_path, filetype = "image/png",width = 300))
}, deleteFile = FALSE)}
</code></pre>
<p>For species in which only one Area is available (and therefore only one folder), the image is displayed, but when there is more than one area, the app returns a blank space, but no error is thrown.</p>
<p>I believe I am correctly defining in which "Area" folder to look for, hen there is more than one option available but I have not been able to figure this one out.</p>
<p>Thanks</p>

(0x800a138f) Unhandled exception in IE8 after adding BreezeJS to Durandal project
|
<p>I'm hoping someone with some experience in Breeze/Durandal 2 on .NET 4.0 will be able to assist me with this error, as I'm pretty new to the mix.</p>
<p>I've been working on a Durandal 2/KO/Require SPA project that lately has been compiling fine and running on my IIS7. I need this app to be compatible with IE8, so I imported the shim and sham js libs as such:</p>
<pre><code> <!-- ECMAScript 5 compatibility shims for IE8 -->
<!--[if lt IE 9]>
<script src="lib/ie8/html5shiv.min.js"></script>
<script src="lib/ie8/respond.js"></script>
<script src="lib/ie8/es5-shim.min.js"></script>
<script src="lib/ie8/es5-sham.min.js"></script>
<![endif]-->
<script src="lib/jquery/jquery-1.9.1.min.js"></script>
<script src="lib/knockout/knockout-3.1.0.js"></script>
<script src="/Scripts/q.min.js"></script>
<script src="/Scripts/breeze.debug.js"></script>
<script src="lib/bootstrap/js/bootstrap.js"></script>
</code></pre>
<p>I also need to be able to access data from a DB so I tried adding BreezeJS to the mix. According to Breeze's documentation, in order for this to work I had to remake the project in VS as ASP.NET MVC4 Project using the Empty Template. After that I imported the Breeze files using NuGet: </p>
<pre><code>Install-Package Breeze.WebApi
</code></pre>
<p>Then I added in my pre-existing views, controllers, libraries, css, etc. to the newly created project. Now when I compile using IE8 I get the following error. This error does not show up for Firefox or Chrome:</p>
<pre><code>Unhandled exception at line 125, column 13 in
http://localhost:64185/lib/durandal/js/composition.js
(Edited for readability)

Unhandled exception at line 125, column 13 in http://localhost:64185/lib/durandal/js/composition.js
</code></pre>
<p>0x800a138f - Microsoft JScript runtime error: 'route' is null or not an object</p>
<p>I thought this might be a compatibility issue with JQuery so I attempted different versions there. I've made sure that my DocType is set to: </p>
<pre><code><!DOCTYPE html>
</code></pre>
<p>and that I have the following meta tag:</p>
<pre><code><meta http-equiv="X-UA-Compatible" content="IE=edge, chrome=1" />
</code></pre>
<p>However I doubt either of those would cause issues with IE8 and Durandal. Has anyone else experienced a similar issue to mine? Am I experiencing this error because I haven't configured something on the MVC4 side? </p>
<p>Any advice would be greatly appreciated.</p>
<p>Thank you</p>

PDF in pop up for mobile devices
|
<p>I am working on a project using the C# MvC .NET 4.0 framework with razor.</p>
<p>I have recently jumped onto the bootstrap bandwagon (Bootstrap v3.3.4 )in order to make our website responsive. I have been trying to find a solution for making pdf's appear as a pop up once clicked. This pop up would need to be scrollable / closable.</p>
<p>I have investigated two approaches:</p>
<ol>
<li>Using a partial view / fancybox. Unfortunately all the examples that came up were purely ASP.NET, hence I could not find anything useful.</li>
<li><p>Embedding PDF's inside the bootstrap modal with an object tag. This was only partially successful: I encountered the following trhee issues whilst browsing and scrolling pdf's embedded in modals on actual mobile devices (iPhone 4S, Safari / Chrome):</p>
<ul>
<li>Scrolling the PDF too aggressively could cause the modal to crash</li>
<li>Scrolling in the modal was unreliable, sometimes the background page would scroll instead of the actual modal. Upon zooming in or out it was often impossible to scroll at all.</li>
<li>Zooming in and out of the PDF was unreliable; only worked sometimes.</li>
</ul></li>
</ol>
<p>For what its worth, below is my .cshtml modal code:</p>
<pre><code><div>
<div class="container">
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open PDF</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">&times;</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body scroll">
<object type="application/pdf" data="http://www.inkwelleditorial.com/pdfSample.pdf" width="500" height="650">this is not working as expected</object>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
</code></pre>
<p></p>
<p>So the way I see it, either I find a way to return pdfs in a scrollable pop up fancybox / partial view or I find a way to fix the scrolling and reliability issues with the modal as it already works partially, but not reliably as stated above.</p>
<p>Any alternative suggestions as to how to get pdf's to work reliably as pop up's on mobile devices would be greatly appreciated.</p>

Writing a regular expression for my specific code
|
<p>I've been trying to get help with this for a few days now, I've asked a dozen questions, all of which get marked duplicate (Which after thorough investigation of the linked questions, I find out it's a different issue) and a few unhelpful comments. This time, I'm coming at it from a different angle.
So far, I've got this working:</p>
<pre><code>var themes = [
'red',
'pink',
'purple',
'deep-purple',
'indigo',
'blue',
'light-blue',
'cyan',
'teal',
'green',
'lime',
'khaki',
'yellow',
'amber',
'orange',
'deep-orange',
'blue-grey',
'brown',
'grey',
'dark-grey',
'black'
]
themes.forEach((theme)=>{
HTTP.get('https://www.w3schools.com/lib/w3-theme-${theme}.css', (err, res)=>{
console.log(`/*${theme}*/\n${res.content
.replace(/w3-theme/g, theme)
.replace(/w3-text-theme/g, `${theme}-text`)
.replace(/w3-border-theme/g, `${theme}-border`)
.replace(/w3-hover-theme/g, `${theme}-hover`)
.replace(/w3-hover-text-theme/g, `${theme}-hover-text`)
.replace(/w3-hover-border-theme/g, `${theme}-hover-border`)
.replace(`${theme}-action`, `btn-${theme}`)
}\n`)
})
}
</code></pre>
<p>It's output is one of these for each color:</p>
<pre><code>/*lime*/
.lime-l5 {color:#000 !important; background-color:#fcfdf3 !important}
.lime-l4 {color:#000 !important; background-color:#f5f8d7 !important}

.lime-hover-text:hover {color:#cddc39 !important}
.lime-hover-border:hover {border-color:#cddc39 !important}
</code></pre>
<p>I have tried adding the following, in almost every variation I can fathom (I.E. Adding flags, changing notation, breaking it up, etc.): </p>
<pre><code>.replace(/(\.(.*)-l4 .*#(.*?) .*#(.*) .*}(\n.*?)*-light.*?#(.*?) .*#(.*) .*})/, `$1\n.btn-$2-light {color:#$6 !important; background-color: #$7 !important}\n.btn-$2-light:hover {color:#$3 !important; background-color:#$4 !important; border-color:#$4 !important}`)
</code></pre>
<p>To no avail, it find 0 matches contrary to <a href="https://regex101.com/r/lC0eFT/4/" rel="nofollow noreferrer">My online tests</a>. </p>
<p>My question is: How should I go about adding those 2 lines?</p>

I didn't get <code>result</code> in <code>result_view</code> function using current method.</p>

LDAP binding on Windows vs. VCE
|
<p>I have been given the simple task to do Windows authentication against the AD from a Windows Compact 7 device in a C# app. Now - 14 days later I'm still struggling, so any help would be greatly appreciated.</p>
<p>Anyway - what I’ve managed to come up with so far is doing Windows authentication on my PC using the wldap32.dll. I’m far from a C++ expert, and with Visual C++ even less so, so bear with me.
Here is my C++ code:</p>
<pre><code>EXPORT_METHOD unsigned long Authenticate(char *userName, char *password, char *domain)
{
unsigned long result = 0;
unsigned short *uUserName = (unsigned short *)userName;
unsigned short *uPassword = (unsigned short *)password;
unsigned short *uDomain = (unsigned short *)domain;
PWCHAR hostName = NULL;
LDAP* pLdapConnection = NULL;
ULONG version = LDAP_VERSION3;
size_t origsize = strlen("ELLAB.COM") + 1;
size_t convertedChars = 0;
wchar_t wcstring[100];
mbstowcs_s(&convertedChars, wcstring, origsize, "ELLAB.COM", _TRUNCATE);
wcscat_s(wcstring, L" (wchar_t *)");
hostName = wcstring;
// Initialize a session. LDAP_PORT is the default port, 389.
pLdapConnection = ldap_init(hostName, LDAP_PORT);
if (pLdapConnection == NULL)
{
#ifdef DEBUG
AfxMessageBox(_T("Unable to Init"));
#endif // DEBUG
result = 0xff;
}
else
{
// Set the version to 3.0 (default is 2.0).
result = ldap_set_option(pLdapConnection, LDAP_OPT_PROTOCOL_VERSION, (void*)&version);
if (result != LDAP_SUCCESS)
{
#ifdef DEBUG
AfxMessageBox(_T("Unable to Set Optins"));
#endif // DEBUG
}
else
{
// Connect to the server.
result = ldap_connect(pLdapConnection, NULL);
if (result != LDAP_SUCCESS)
{
#ifdef DEBUG
AfxMessageBox(_T("Unable to Connect"));
#endif // DEBUG
}
else
{
// Be aware that the password itself is never sent over the network, and encryption is not used.
SEC_WINNT_AUTH_IDENTITY NtAuthIdentity;
ZeroMemory(&NtAuthIdentity, sizeof(NtAuthIdentity));
NtAuthIdentity.Flags = SEC_WINNT_AUTH_IDENTITY_UNICODE;
NtAuthIdentity.Domain = uDomain;
NtAuthIdentity.DomainLength = sizeof(uDomain);
NtAuthIdentity.User = uUserName;
NtAuthIdentity.UserLength = sizeof(uUserName);
NtAuthIdentity.Password = uPassword;
NtAuthIdentity.PasswordLength = sizeof(uPassword);
//if (ldap_bind_s(pLdapConnection, NULL, NULL, LDAP_AUTH_NEGOTIATE) == LDAP_SUCCESS)
result = ldap_bind_s(pLdapConnection, NULL, (PWCHAR)&NtAuthIdentity, LDAP_AUTH_NTLM);
//if (result != LDAP_SUCCESS)
{
#ifdef DEBUG
AfxMessageBox(_T("Unable to Bind using ldap_bind_s"));
#endif // DEBUG
result = ldap_bind(pLdapConnection, NULL, (PWCHAR)&NtAuthIdentity, LDAP_AUTH_NTLM);
if (result != LDAP_SUCCESS)
{
#ifdef DEBUG
AfxMessageBox(_T("Unable to Bind using ldap_bind"));
#endif // DEBUG
}
}
}
}
// Normal cleanup and exit.
ldap_unbind(pLdapConnection);
}
return result;
}
</code></pre>
<p>And my C# sample wrapper:</p>
<pre><code>[DllImport(@"C:\Users\ckbn.ELLAB\Documents\Visual Studio 2015\Projects\WCE7_LDAP\Debug\LDAPHandler.dll", CharSet = CharSet.Unicode)]
public static extern int Authenticate(string userName, string password, string domain);
private void buttonAuthenticate_Click(object sender, EventArgs e)
{
try
{
textBoxResult.Text = "";
LDAPReturns result = (LDAPReturns)Authenticate(textBoxUserName.Text, textBoxPassword.Text, textBoxDomain.Text);
switch (result)
{
case LDAPReturns.LDAP_SUCCESS:
textBoxResult.Text = "User '" + textBoxUserName.Text + "' is authenticated";
break;
default:
textBoxResult.Text = result.ToString();
break;
}
}
catch (Exception ex) { textBoxResult.Text = "Failed: " + ex.ToString(); }
}
</code></pre>
<p>So - using the above code I can authenticate with my own credentials on my PC. Running the same code on the WCE device, I can connect to the AD server, but when I try to ldap_bind_s, it returns LDAP_AUTH_METHOD_NOT_SUPPORTED. So I’m thinking the the ARM version of the wldap32.dll is different from the x86 version. </p>
<p>Then I tried to use the ldap_bind (without ‘_s’) method. This is not working nighter on my PC nor on the WCE device and always returns 0xFFFF_FFFF.</p>
<p>So basically my questions are:</p>
<p>What does LDAP_AUTH_METHOD_NOT_SUPPORTED means, and what other methods do I have on a WCE7 device? and</p>
<p>What does it means when ldap_bind returns 0xFFFF_FFFF?</p>
<p>But any input or suggestion would be highly appreciated. Thanks in advance!</p>

MonoMac Create Mac Installer results in Merging Mono Failed. FATAL UNHANDLED EXCEPTION

<p>I am using MonoDevelop 2.8.8.4 and MonoFramework (MDK) 2.10.9_8. I'm also using Mac OSX Lion 10.7.3 and have installed XCode 4.3.1 for Lion SDK. My MonoMac application runs fine when debugging with MonoDevelop. Then I tried to create the Application Bundle by going to Project -> Create Mac Installer... </p>

Problem with import javax.persistence.EntityManager;
|
<p>Hey I want to make projects using databases. I've found some tutorials on youtube, but I have problem with Java JPA/Hibernate. Even tho I am following each step I just cant get to import in my class</p>
<pre><code>import javax.persistence.EntityManage
</code></pre>
<p>I am using IntelliJ and here is how I am trying to do it.
First I create maven project without archetypes.
Then in my pom.xml file which for some reason looks different than the one in tutorial.</p>
<p>I am adding dependencies.</p>
<pre><code><dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.4.28.Final</version>
</dependency>
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>javax.persistence-api</artifactId>
<version>2.2</version>
</dependency>
</code></pre>
<p>The second one might not be needed, but I am trying everything at this point. At the end my pom.xml file looks like:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<dependency>

<artifactId>hibernate-core</artifactId>
<version>5.4.28.Final</version>
</dependency>
</dependencies>
</project>
</code></pre>
<p>In my pom file there are no errors.
I have also made persistence.xml file, but the problem appears before it matters.
I've spent few hours looking for solution and I am so angry at myself that I cant get over such a easy thing, but I have no idea what am I doing wrong. I literally follow tutorial that clearly works.</p>

Selenium 'dies' when visiting some websites using Behat / Mink
|
<p>I'm trying to create a a custom scenario in Behat / Mink using the javascript capabilities of Selenium but I've hit a peculiar snag. I've stripped everything back to the bare bones to lay the problem out as simply as possible but in summary when calling visit() in Selenium, some websites run fine but other (including my own) return the error "Error communicating with the remote browser. It may have died." in behat which terminates the scenario.</p>
<p>In detail:</p>
<p>My behat.yml file looks like this:</p>
<pre><code>default:
paths:
features: features
bootstrap: %behat.paths.features%/bootstrap
extensions:
Behat\MinkExtension\Extension:
base_url: http://www.foo.bar
goutte: ~
selenium2:
browser: 'firefox'
</code></pre>
<p>In my FeatureContext.php file I have the following custom function:</p>
<pre><code>public function iAmLoggedIn()
{
$session = $this->getSession();
$session->visit("http://www.foo.bar");
{
</code></pre>
<p>Now when I run the scenario in Behat that uses the custom function I get the following error:</p>
<pre><code>PHP Fatal error: Uncaught exception 'WebDriver\Exception\UnknownError' with message 'Error communicating with the remote browser. It may have died.
Build info: version: '2.44.0', revision: '76d78cf', time: '2014-10-23 20:02:37'
Driver info: driver.version: EventFiringWebDriver' in /var/www/behat/vendor/instaclick/php-webdriver/lib/WebDriver/Exception.php:157
Stack trace:
#0 /var/www/behat/vendor/instaclick/php-webdriver/lib/WebDriver/AbstractWebDriver.php(140): WebDriver\Exception::factory(13, 'Error communica...')
#1 /var/www/behat/vendor/instaclick/php-webdriver/lib/WebDriver/Session.php(151): WebDriver\AbstractWebDriver->curl('DELETE', '')

</code></pre>
<p>But here's the oddity: thinking that this may have been an issue with my website (www.foo.bar) I tried a different website by editing the line on the function:</p>
<pre><code>$session->visit("http://www.bbc.co.uk");
</code></pre>
<p>This time no error and the scenario continues as normal. Good old BBC. To make sure I also tried Goole:</p>
<pre><code>$session->visit("http://www.google.com");
</code></pre>
<p>But this time I get exactly the same error: 'Error communicating with the remote browser. It may have died.'. Weird. So I try a number of other websites, some work fine, others return this error. There doesn't seem to be any obvious similarity between those sites that kill Selenium, and those that don't. So what is Selenium saying?</p>
<p>Output from a site that returns the 'It may have died' error:</p>

<p>No clue there apart from the fact that Selenium completes the 'get' of bbc.co.uk but not of foo.bar. So what about the access logs for foo.bar? They seem normal:</p>

</code></pre>
<p>10.179.?.? being the IP of the CI server so it's communicating with the server fine and retrieving all the assets. So I'm not sure if this is a Selenium issue or a Behat / Mink issue but I'm at a loss. There doesn't seem to be any logical reason why some sites work and other's don't. Any help would be greatly appreciated.</p>

Leiningen isn't checking Maven directory
|
<p>I have a Clojure project that I'm writing using Intellij and the Cursive and Leiningen plugins.</p>
<p>My problem is, Leiningen isn't checking the central Maven directory when finding dependencies. <code>water-time</code> is my current project, and <code>helpers</code> is the project containing "helper" functions that I want to include.</p>
<p>First, my file structure:</p>
<ul>
<li>IdeaProjects
<ul>
<li>helpers
<ul>
<li>project.clj</li>
<li>src
<ul>
<li>helpers
<ul>
<li>general_helpers.clj</li>
</ul></li>
</ul></li>
</ul></li>
<li>water-timer
<ul>
<li>project.clj</li>
<li>src
<ul>
<li>water_timer
<ul>
<li>tone_producer.clj</li>
</ul></li>
</ul></li>
</ul></li>
</ul></li>
</ul>
<p>helper's project.clj:</p>
<pre><code>(defproject helpers "1"
:description "General Helper Library"
:dependencies [[org.clojure/clojure "1.8.0"]])
</code></pre>
<p>water-timer's project.clj:</p>
<pre><code>(defproject water-timer "1"
:description "A timer that reminds you to drink water"
:dependencies [[org.clojure/clojure "1.8.0"]
[helpers "1"]]
:main water-timer.tone-producer
:aot [water-timer.tone-producer])
</code></pre>
<p>tone_producer.clj with irrelevant bits removed:</p>
<pre><code>(ns tone-producer
(:require [general-helpers :as g])
(:gen-class))
(defn -main [& args]
(println "Test!"))
</code></pre>
<p>Both projects were created using <code>lein new</code>. I had originally created them using Intellij, but in my <a href="https://stackoverflow.com/questions/38329515/cant-build-a-jar-using-leiningen">previous question</a>, it was recommended that I create the projects using leiningen, and then import them, so I recreated them from scratch.</p>
<p>If I then cd into <code>helpers</code> and run <code>lein install</code>, it successfully installs <code>helpers</code> into the Maven directory (<code>[my-name]\.m2\repository\helpers\helpers\1\helpers-1.jar</code>).</p>
<p>When I try to use the files though (by trying to create a uberjar using leiningen), it complains that it can't find the dependencies; even if I run <code>lein deps</code> prior:</p>
<pre><code>"C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 2016.1.2\jre\jre\bin\java" -Dvisualvm.id=91626738132760 -Dfile.encoding=UTF-8 -Dmaven.wagon.http.ssl.easy=false -Dmaven.wagon.rto=10000 -Didea.launcher.port=7541 "-Didea.launcher.bin.path=C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 2016.1.2\bin" -classpath "C:\Users\slomi\.lein\self-installs\leiningen-2.6.1-standalone.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 2016.1.2\lib\idea_rt.jar" com.intellij.rt.execution.application.AppMain clojure.main -m leiningen.core.main uberjar

</code></pre>
<p>The thing that concerns me is the classpath it prints at the top of the error doesn't include the <code>.m2</code> directory. It is my understanding that leiningen looks in that directory when trying to resolve dependencies, so I'm confused as to why it isn't looking there.</p>
<p>What am I missing here? All I want to do is make a executable jar that depends on a local source!</p>

PHP contact form verification field

<p>Using the script below (taken from a template), I added a simple verification question to prevent spam (What is 2 + 2?). As of now, when the submit button is filled, the error.php page appears but the form is submitted as blank. </p>
<p>How do I ensure the form is only submitted after verifying the security question? </p>
<pre><code><?php
$EmailTo = "myemail@email.com";
$Subject = "website";
$name = Trim(stripslashes($_POST['name']));
$email = Trim(stripslashes($_POST['email']));
$number = Trim(stripslashes($_POST['number']));
$message = Trim(stripslashes($_POST['message']));
// validation
$validationOK=true;
if (!$validationOK) {
print "<meta http-equiv=\"refresh\" content=\"0;URL=error.php\">";
exit;
}
// prepare email body text
$Body = "";
$Body .= "Name: ";

Swift: Trying to get my statusbar back - stopping view from writing below the safespace
|
<p>I got my function:</p>
<pre><code> func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: view.frame.width, height: view.frame.height)
}
</code></pre>
<p>And I want to minus the view.frame.height, with the height of the statusbar.
The closest thing I could find was this: <a href="https://stackoverflow.com/questions/12991935/how-to-programmatically-get-ios-status-bar-height">How to programmatically get iOS status bar height</a></p>
<p>I've tried: </p>
<blockquote>
<p>view.frame.height - [UIApplication
sharedApplication].statusBarFrame.size.height</p>
<p>view.frame.height - 20.0f</p>
<p>view.frame.height - 20</p>
</blockquote>
<p>But none of them works as I would hope. I believe it uses pixels, instead of points at the last one, the first two doesn't run at all.</p>
<p>What I'm looking for is:
view.frame.height - statusBarHeight</p>
<p>If it helps, here is my entire viewController.</p>

How to add Values in a UITableViewCell

<pre><code> import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
struct Question {
var id: Int
var questionText: String
var answers: [String]
var correctAnswer: Int
}
var question1 = Question(id: 1, questionText: "Foo?", answers:["1", "2", "3", "4"], correctAnswer: 2)
var question2 = Question(id: 2, questionText: "Bar?", answers:["1", "2", "3", "4"], correctAnswer: 2)
var question3 = Question(id: 3, questionText: "Baz?", answers:["1", "2", "3", "4"], correctAnswer: 2)

Docker-Compose: how to configure container with VPN Split-Tunnelling?
|
<p>I need the network traffic of a Docker service to pass through VPN,
and also to be able to reach other containers outside VPN from that container.</p>
<p>I'm able to get the first requirement working by configuring an <code>OpenConnect</code> service</p>
<pre><code>version: "3.8"
services:
open-connect:
container_name: open-connect
image: open-connect
build:
dockerfile: Docker/OpenConnect.Dockerfile
context: .
privileged: true
environment:
- VPN_PROTOCOL
- VPN_HOST
- VPN_PORT
- VPN_USERNAME
- VPN_PASSWORD
</code></pre>
<p>and making the traffic of the other service pass through it via <code>network_mode: container:open-connect</code></p>
<pre><code>version: "3.8"
services:
vpn-client:
container_name: vpn-client
image: vpn-client
build:
dockerfile: Docker/Busybox.Dockerfile
context: ..
network_mode: container:open-connect
service-a:
hostname: service-a
container_name: service-a
image: service-a
build:
dockerfile: Docker/Busybox.Dockerfile
context: ..
networks:
backend:
service-b:
hostname: service-b
container_name: service-b
image: service-b
build:
dockerfile: Docker/Busybox.Dockerfile
context: ..
networks:
backend:
networks:
backend:
</code></pre>
<p>The problem is that only <code>service-a</code> and <code>service-b</code> are able to ping each other.</p>
<p>From <code>vpn-client</code> it is not possible to reach neither <code>service-a</code> or <code>service-b</code>,
similarly in the reverse way.</p>
<p>I cannot combine <code>network-mode</code> and <code>networks</code> in the <code>vpn-client</code> service:</p>
<pre><code>ERROR: 'network_mode' and 'networks' cannot be combined
</code></pre>
<p>What else can be done to make the <code>vpn-client</code>, <code>service-a</code> and <code>service-b</code> mutually reachable without being all of them behind <code>VPN network</code>?</p>
<hr />
<p><strong>Update</strong></p>
<p><strong>VPN Split Tunnelling</strong></p>
<p>Based on some resources I found, the solution seems to be the
configuration of VPN with <code>split-tunnelling</code> instead of <code>full-tunneling</code>.</p>
<ul>
<li><a href="https://cybernews.com/what-is-vpn/split-tunneling/" rel="nofollow noreferrer">https://cybernews.com/what-is-vpn/split-tunneling/</a></li>
<li><a href="https://gist.github.com/stefancocora/686bbce938f27ef72649a181e7bd0158" rel="nofollow noreferrer">https://gist.github.com/stefancocora/686bbce938f27ef72649a181e7bd0158</a></li>
<li><a href="https://gist.github.com/jagtesh/5531300" rel="nofollow noreferrer">https://gist.github.com/jagtesh/5531300</a></li>
</ul>
<p>So the question becomes: how to configure VPN split-tunnelling in the <code>open-connect</code> service?</p>

Opening modal from dropdown list to add client

Post not working in Ajax to save the input to database
|
<p>I am trying to save an event via ajax on the full calendar.</p>
<p>I have tested the php for inserting the events and it is working fine. So I realized that the events are not being passed via ajax.</p>
<p>They are not being passed for insertion or updatation.</p>
<pre><code><script>
$(document).ready(function() {
var date = new Date();
var d = date.getDate();
var m = date.getMonth();
var y = date.getFullYear();
var calendar = $('#calendar').fullCalendar({

center: 'title',
right: 'month,agendaWeek,agendaDay'
},
events: "events.php",
// Convert the allDay from string to boolean
eventRender: function(event, element, view) {
if (event.allDay === 'true') {
event.allDay = true;
} else {
event.allDay = false;
}
},

var title = prompt('Event Title:');
var url = prompt('Type Event url, if exits:');

</code></pre>
<p>Here is the insertion code (add_events.php)</p>
<pre><code> $title = $_POST['title'];

} catch(Exception $e) {
exit('Unable to connect to database.');
}
// insert the records
$sql = "INSERT INTO evenement (title, start, end, url) VALUES (:title, :start, :end, :url)";
$q = $bdd->prepare($sql);
$q->execute(array(':title'=>$title, ':start'=>$start, ':end'=>$end, ':url'=>$url));
</code></pre>
<p>And here is the update_events for updating the event :</p>
<pre><code> /* Values received via ajax */
$id = $_POST['id'];
$title = $_POST['title'];
$start = $_POST['start'];
$end = $_POST['end'];
// connection to the database
try {
$bdd = new PDO('mysql:host=localhost;dbname=fullcalendar', 'umar', 'Umar@295');

// update the records
$sql = "UPDATE `evenement` SET 'title'=?, 'start'=?, 'end'=? WHERE 'id'=?";
$q = $bdd->prepare($sql);
$q->execute(array($title,$start,$end,$id));
</code></pre>
<p>I would appreciate if someone could point me into understanding how to get the POST in the Ajax working or what I am doing wrong.</p>

Google maps view android.view.InflateException: Binary XML File - error inflating class fragment

<p>This happened overnight after finishing this piece of code which pulls coordinates (Latitude and Longitude) from an API and displaying those coordinates with Markers onto a GoogleMap. It was working fine until this morning when I decided to implement a refresh page code. Even after I removed it just to double check, the error still remains.</p>

<p>As you can see i'm trying to map the enty and sub entities to the view model and sub view models. The problem is when trying to do it with ICollections. I have no idea how to deal with this in lambda expression</p>

AngularJS ES6 parent function not being called by child component
|
<p>I'm a bit new to the ES6 syntax/structure of Angular 1.x, and I'm running into an issue with passing a function from a parent controller to a child controller.</p>
<p>This is how the app is tied together (I use webpack + babel with this as the entry-point):</p>
<pre><code>const requires = [
'ngRoute',
];
//App
angular.module('kanban',requires)
.controller('dashboardCtrl', dashboardCtrl)
.component('board', board)
.component('task', task)
.config(routes);
</code></pre>
<p>In my routes, I have a single route, which is my 'parent'</p>
<pre><code>export default function($routeProvider) {
$routeProvider
.when('/', {
template: dashboardTemplate,
controller: 'dashboardCtrl',
controllerAs: '$ctrl',
});
}
</code></pre>
<p>Who's controller looks like this:</p>
<pre><code>export default function($rootScope) {
$rootScope.title = 'Kanban';
let _this = this;
this.boards = [
{
_id: 'b1',
title: 'backlog',
tasks: ['t1', 't2'],
}
];
this.deleteBoard = function(board) {
console.log(board);
let index = _this.boards.indexOf(board);
if (index !== -1) {
_this.boards.splice(index, 1);
}
};
</code></pre>
<p>And in the template, the child is created with ng-repeat, passing in the function</p>
<pre><code><board ng-repeat="board in $ctrl.boards" board="board" onDelete="$ctrl.deleteBoard(board)" ></board>
</code></pre>
<p>And the board binds the attribute as a function with an &</p>
<pre><code>export const board = {
template: boardTemplate,
controller: boardCtrl,
bindings: {
board: '=',
onDelete: '&',
}
};
</code></pre>
<p>And the function is added to the controller within a different function:</p>
<pre><code>export default function boardCtrl() {
let _this = this;
this.deleteBoard = function(){
console.log(_this.onDelete);
_this.onDelete({board: _this.board});
};
}
</code></pre>
<p>And called with a click:</p>
<pre><code><button ng-click="$ctrl.deleteBoard()"></button>
</code></pre>
<p>I can reach the board (child) controller's function, which prints this in the console:</p>
<pre><code>function (locals) {
return parentGet(scope, locals);
}
</code></pre>
<p>And returns no errors, but the console.log in the parent deleteBoard function does not get called.</p>
<p>What is happening here? Why does the child seem to recognize that it is calling something in the parent scope, but is not reaching it?</p>

Using an adapter for two different situations
|
<p>I have a regular <code>RecyclerView</code> adapter that looks like this:</p>
<pre><code>public class MessageAdapter extends RecyclerView.Adapter<MessageAdapter.ViewHolder> {
private static final String TAG = "MessageAdapter";
private Context context;
private List<Message> messages;
public MessageAdapter(Context context, List<Message> messages) {
this.context = context;
this.messages = messages;
}
public class ViewHolder extends RecyclerView.ViewHolder {
public Message message;
public TextView messageUser, messageText, messageTime;
public ViewHolder(View v) {
super(v);
messageUser = (TextView) v.findViewById(R.id.messageUser);
messageText = (TextView) v.findViewById(R.id.messageText);
messageTime = (TextView) v.findViewById(R.id.messageTime);
}
public void setMessage(Message message) {
this.message = message;
}
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.message_layout, parent, false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(final ViewHolder holder, int position) {
Message message = messages.get(position);
holder.setMessage(message);
holder.messageUser.setText(message.getUser());
holder.messageText.setText(message.getText());
holder.messageTime.setText(message.getTime());
}
@Override
public int getItemCount() {
return messages.size();
}
}
</code></pre>
<p>I use this adapter to list all messages the user has received in the main activity.</p>
<p>In addition to this, I am using the <a href="https://github.com/bmelnychuk/AndroidTreeView" rel="nofollow noreferrer">AndroidTreeView library</a> in a different part of my app that also displays the user's messages (but in a treeview layout).</p>
<p>However, reading the documentation of this library, it says that in order to create an adapter for the treeview data, it must have the following format (taken from the docs):</p>
<pre><code>public class MyHolder extends TreeNode.BaseNodeViewHolder<IconTreeItem> {
...
@Override
public View createNodeView(TreeNode node, IconTreeItem value) {
final LayoutInflater inflater = LayoutInflater.from(context);
final View view = inflater.inflate(R.layout.layout_profile_node, null, false);
TextView tvValue = (TextView) view.findViewById(R.id.node_value);
tvValue.setText(value.text);
return view;
}
...
public static class IconTreeItem {
public int icon;
public String text;
}
}
</code></pre>
<p>So I created a second message adapter (specifically for the AndroidTreeView library) that looks like this:</p>
<pre><code>public class MessageTreeAdapter extends TreeNode.BaseNodeViewHolder<MessageTreeAdapter.TreeItem> {
private TextView messageUser;
private TextView messageText;
private TextView messageTime;
public MessageTreeAdapter(Context context) {
super(context);
}
@Override
public View createNodeView(TreeNode node, TreeItem value) {
final LayoutInflater inflater = LayoutInflater.from(context);
final View view = inflater.inflate(R.layout.message_layout, null, false);
Message message = value.message;
messageUser = (TextView) v.findViewById(R.id.messageUser);
messageText = (TextView) v.findViewById(R.id.messageText);
messageTime = (TextView) v.findViewById(R.id.messageTime);
messageUser.setText(message.getUser());
messageText.setText(message.getText());
messageTime.setText(message.getTime());
return view;
}
public static class TreeItem {
public Message message;
public TreeItem(Message message) {
this.message = message;
}
}
}
</code></pre>
<p>But as you can see, I'm repeating what I already have in my first adapter, <code>MessageAdapter.java</code>. I want to avoid this.</p>
<p>So my question is, how can I use a single adapter (<code>MessageAdapter.java</code>) for both situations so that I don't have to repeat any code.</p>

When setting an Adapter it Gives a Null Pointer Exception in fragment

<p>I am a new android learner. I ran into this null pointer exception at <code>setAdapter()</code> for lListView<code>. Both the</code>ListView` and the Adapter are NOT null.
I have attached my logcat and fragament, adapter code. I have searched the Internet, and I thought it might have something to do with Fragment. </p>

Conflict between positional_or_keyword_parameters and var_positional_parameters?
|
<p>I just defined a function in the following when I learn about the knowledge about parameter:</p>
<pre class="lang-py prettyprint-override"><code>>>> def f1(a, b, /, c=0, *args,d, **kw):
print('a =', a, 'b =', b, 'c =', c, 'args =', args, 'd = ', d, 'kw =', kw)
</code></pre>
<p>And it seems to be running well in my first try:</p>
<pre class="lang-py prettyprint-override"><code>>>> f1(1,2,3,*[4,5,6],d=7,e=8)
a = 1 b = 2 c = 3 args = (4, 5, 6) d = 7 kw = {'e': 8}
</code></pre>
<p>However, when I do modification about the argument for "c", which is known as positional_or_keyword_parameters in python, the running results beyond my expectation.</p>
<p>I trying to run:</p>
<pre class="lang-py prettyprint-override"><code>>>>f1(1,2,c=3,*[4,5,6],d=7,e=8)
>>>f1(1,2,*[4,5,6],d=7,e=8)
</code></pre>
<p>In my expectation, the result will be:</p>
<pre class="lang-py prettyprint-override"><code>a = 1 b = 2 c = 3 args = (4, 5, 6) d = 7 kw = {'e': 8}
a = 1 b = 2 c = 0 args = (4, 5, 6) d = 7 kw = {'e': 8}
</code></pre>
<p>But the reality is:</p>
<pre class="lang-py prettyprint-override"><code>>>> f1(1,2,c=3,*[4,5,6],d=7,e=8)
Traceback (most recent call last):
File "<pyshell#20>", line 1, in <module>
f1(1,2,c=3,*[4,5,6],d=7,e=8)
TypeError: f1() got multiple values for argument 'c'
>>> f1(1,2,*[4,5,6],d=7,e=8)
a = 1 b = 2 c = 4 args = (5, 6) d = 7 kw = {'e': 8}
</code></pre>
<p>Then I look up the python documentation. What surprised me was that there is not any example codes in python documentation like mine. I mean, the example codes like:</p>
<pre class="lang-py prettyprint-override"><code>#the define:
def f(a, b, /, c, d, *, e, f):
def func(posonly1, posonly2, /, positional_or_keyword): ...
def func(*args, **kwargs): ...
</code></pre>
<p>In these case, the positional_or_keyword_parameters and the var_positional_parameters cannot be present at the same time.</p>
<p>Is that the truth?The syntax of python does not support that the positional_or_keyword_parameters and the var_positional_parameters present at the same time？ If it does not, how can I achieve my expectations?</p>
<pre class="lang-py prettyprint-override"><code>>>> def f1(a, b, /, c=0, *args,d, **kw):
print('a =', a, 'b =', b, 'c =', c, 'args =', args, 'd = ', d, 'kw =', kw)
#my expectations:
>>>f1(1,2,c=3,*[4,5,6],d=7,e=8)
a = 1 b = 2 c = 3 args = (4, 5, 6) d = 7 kw = {'e': 8}
>>>
>>>f1(1,2,*[4,5,6],d=7,e=8)
a = 1 b = 2 c = 0 args = (4, 5, 6) d = 7 kw = {'e': 8}
>>>
</code></pre>
<hr />
<p>@Programmer:</p>
<p>In your answer, you gave me advice on function definition:</p>
<pre><code>def f1(a, b, /, d, *args, c=0, **kw):
</code></pre>
<p>I see that the parameter <em>d</em> is defined without a default value, but <em>d</em> is opposite. Let us talk about something more interesting about this.</p>
<p>In my opinion, the level of mastery of a syntax depends on making it useful, not just using it correctly. I would like to do a split of your codes and ignore some elements, it will like like:</p>
<pre class="lang-py prettyprint-override"><code>#define f1
def f1(a, b, /, d=0): #I prefer to do so, defining positional_or_keyword_parameters with default value
#define f2
def f2(*args,c) or def f2(*args,c=0) #define keyword_only_parameters with or without default value
</code></pre>
<p>Function definition like <em>f1</em>() is useful, think about the python function <em>range()</em>:</p>
<pre class="lang-py prettyprint-override"><code>#I assume the definition of range() is liking the following
def range(start, /, stop=None, step=1): #the dedault value is frequently used
if stop is None: #use a few tips
stop = start
start = 0
...
#I defined the positional_or_keyword_parameters(just "stop" and "step") with default value
#Therefore, I can generate the following instances:
range(10) #when I don't need the "stop" and "step", codes can be simple
range(0,10) #I need "start" and "stop" but not "step", I can still ignore the value of "step"
range(0,10,1) #I need all of them, however, I can still avoid complex syntax checks
#In short, this parameters definiton() make us more focusing on the polymorphism of functions and generating an instance by a very simple way, rather than doing complex syntax checks again and again
#Imagine this...
def range(start,/,stop=None,step): # define positional_or_keyword_parameters without default value
...
>>>range(10,step=1) #I have to write the stupid "step=1" again and again
>>>range(5,step=1)
>>>range(3,step=1)
>>>range(1,10,1) #I have to write the stupid "1" again and again
>>>range(2,5,1)
>>>range(3,6,1)
</code></pre>
<p>The situation is reversed when I define the function like <em>f2()</em>, think about the python function <em>max()</em>:</p>
<pre class="lang-py prettyprint-override"><code>#I assume the definition of max() is liking the following
def max(*args,key) or def max(*args,key=abs) :
...
#They are all useful
#In this case, max() must receive var_positional_parameters at first, and then use keyword_only_parameters("key" in this case) to achieve the polymorphism of functions. If the keyword_only_parameters without default value, it will make a serious situations that user of max() must explicitly what he/she do with the max(), and still no loss the polymorphism of functions. Relativily, the case of keyword_only_parameters with default value do more convenience but less strictness.
#example codes
max(1,2,3,4,5,6,7,8,9,10,key=abs) # *args is so long... the length of "key=abs" is easy to accept
max(*list) # It's convenient
</code></pre>
<p>Back to the main topic, my question about the definition like:</p>
<pre class="lang-py prettyprint-override"><code>def f1(a, b, /, c=0, *args,d, **kw):
...
# let us ignore irrelevant elements, it will be:
def f1(/, c=0, *args,d):
</code></pre>
<p>In fact, I loss of interest about it in few hours. The reason is that I can't figure out why I have to define a function like it. Its syntax is correct , but useless at the same time. At least I can't think of any use for it.</p>
<p>A useless syntax ...</p>
<p>Maybe my question is really boring...</p>

Receiving Promise<Void> instead of NSMutableURLRequest
|
<p>I'm attempting to login to my app, however, all my APIRequests are showing as Void instead of APIRequest. This function was working back in Swift 2 and has since gone through some minor changes to attempt to migrate from PromiseKit 4 to PromiseKit 6. </p>
<p>The function does touch a lot of other things, please leave a comment if you need to see more. The function giving me the errors is:</p>
<pre><code>class func recover403(error: Error) -> Promise<NSData> {
if case let APIError.InvalidToken(request) = error {
// Log in, then continue the promise chain
let login = RootViewController.sharedInstance.showLoginController()
return login.then { request -> Promise<NSData> in
return API.transmit(request: request as! APIRequest)
}
} else if case CocoaError.userActivityConnectionUnavailable = error {
let vc = ErrorViewController(nibName: "ErrorViewController", bundle: nil)
let actions = ["Try Again"]
vc.actions = actions
vc.promise.then { index -> Promise<NSData> in
RootViewController.sharedInstance.popAlertViewController()
return API.transmit(request: request as! APIRequest)
}.catch({ (Error) in
// No catch
})
RootViewController.sharedInstance.pushAlertViewController(nvc: vc)
vc.errorLabel.text = "Please check your network connection and try again!"
}
return Promise<NSData>(error: error)
}
</code></pre>
<p>'return API.transmit(request: request as! APIRequest)' is throwing</p>
<pre><code>Error: Value of tuple type 'Void' has no member 'value'

</code></pre>
<p>the 2nd 'return API.transmit(request: request as! APIRequest)' is throwing</p>
<pre><code>Error: Generic parameter 'T' could not be inferred
Warning: Cast from '(String, Any?) -> Promise<_>' to unrelated type 'APIRequest' always fails
</code></pre>
<p>Here is the APIRequest.swift</p>
<pre><code>import Foundation
class APIRequest: NSMutableURLRequest {
var errorConditions: [APIRequestErrorCondition] = []
init(_ path: String, JSON: Any? = nil) {
let URL = NSURL(string: API.baseURL + path)!

How can I slow down a program to make the request to the server?

Make navigation menu span length of browser

<p>I am trying to get my navigation menu to span the entire length of my blog. Right now it is off center to the right and a bit too short. How do I make it longer?</p>
<p>Also, you'll notice that my navigation menu is not at the very top of the page, which is where I would like it to be. How do I fix that as well?</p>
<p>And that's not it! My navigation menu is sticky, but when you scroll past it.. it gets thrown to the left side of the page. What to do?</p>

Drawables next to buttons?

<p>Ive been working on a simple app that has a feature where you can test your knowledge by answering multiple choice questions. After an answer is selected(by the radio button), i want to show either a check mark if the answer is correct, or an "X" if the answer is incorrect, to the right of the selected answer. For some reason, my code works perfectly for the first try, and then doesnt change anything when selecting other answers.</p>

How to build a Docker image?
|
<p>I have a directory named docker which contains the following two files:</p>
<pre><code>docker:
|_Dockerfile
|_main.py
</code></pre>
<p><strong>The Dockerfile looks like this:</strong></p>
<pre><code>#Specifying the base image
FROM python:3.10
#here the dockerfile is pulling the python 3.10 from docker hub which already has python installed so we have all the things we need to have python in our container.
ADD main.py.
#Here we added the python file that we want to run in docker and define its location.
RUN pip install requests pygame
#Here we installed the dependencies, we are using the pygame library in our main.py file so we have to use the pip command for installing the library
CMD [ "python3" "./main.py" ]
#lastly we specified the entry command this line is simply running python ./main.py in our container terminal
</code></pre>
<p><strong>The main.py file looks like this:</strong></p>
<pre><code># Simple pygame program
# Import and initialize the pygame library
import pygame
pygame.init()
# Set up the drawing window
screen = pygame.display.set_mode([500, 500])

How to add margin to nested comments?
|
<p>I am creating a Reddit clone, and right now have the ability to create comments, and sub-comments. Using CSS I was able to add a margin (indentation) to "child" comments (sub-comments). But my "grand-child" comments (sub sub-comments) retain the same level of indentation as my "child" comments. </p>
<p>How can I go about adding a logic that would increment the margin for each sub-comment? Someone suggested using sass, but i've never used it... if that's the best way to go about it, give me a hint (I want to learn). </p>
<p>This is my comment partial </p>
<pre><code><%= div_for(comment) do %>
<div class="comments_wrapper clearfix">
<div class="pull-left">
<!-- Parent Comments -->
<!-- Determines if the comment is parent or not-->
<% if !comment.ancestry? %>
<p class="parent"><%= comment.body %></p>
<p><small>Submitted <strong><%= time_ago_in_words(comment.created_at) %> ago</strong> by <%= comment.user.email %></small></p>
<!--Reply button for parent comment-->
<button onClick="$('#reply<%=comment.id%>').show()" class="btn btn-sm btn-default">Reply</button>
<!--Reply form for parent comment-->
<div id="reply<%=comment.id%>" style="display:none;">
<%= form_for [@link, @comment = Comment.new] do |f| %>
<%= f.hidden_field :ancestry, :value => comment.id %>
<%= f.text_area :body %> <br>
<%= f.submit %>
<% end %>
</div>
<% else %>
<!-- Child Comments -->
<div class="row">

<p class="child"><%= comment.body %></p>
<p><small>Submitted <strong>

<!--Reply button for child comment-->
<button onClick="$('#reply<%=comment.id%>').show()" class="btn btn-sm btn-default">Reply</button>

SQL In Access, Transforming a data table into a structured data table?
|
<p>I'm using Access forms and tables for the purposes of our project. We have an Access form template that sends data to a table (Defaults) when something is changed, added or deleted on the form. The form stores the value in the "DefaultValue" and updates the table with it. Basically, it sends data to the table, updates it on-the-spot (if needed) and retrieves it afterwards to the "DefaultValue" so we can work in our forms with it.</p>
<p>That form data goes into a table [Defaults], which has 3 columns : <em>FormName, ControlName and DefaultVal</em>. Each value in a form gets categorized in the table by its [FormName] and [ControlName], both are primary key. <em>We use the same templated form with different form names multiple times. The form field names in the template are the same. [DefaultVal] has a Memo/LongText column format.</em></p>
<blockquote>
<p>Example: A row in "Defaults" reads <code>Form_Sample|Text224|Test</code>. This means there is a form named "Form_Sample" with a field named "Text224" with the DefaultValue "Test".</p>
</blockquote>
<p>So my question is, I want to pull the data from [Defaults].[DefaultVal] to the table "Analysis". The information needs to go into 7 columns (lets call them column1,2,3,4,etc due to classified company information). To define what data from column "DefaultVal" goes into one of the 7 columns in Analysis, the [ControlName] column needs to be used. Since form field names in our different forms are the same, further categorization is needed so that they don't overwrite. In order to define if the [DefaultVal] is unique, first [FormName] must be used then [ControlName] needs to be added. </p>
<blockquote>
<p>Example: If you have <code>Text224|Apple</code> from one form and <code>Text224|Orange</code> from another, they would overwrite due to the same [ControlName]. However, if we use two primary keys and have <code>Form1|Text224|Apple</code> and <code>Form2|Text224|Orange</code>, they would be unique. This is how our table defines if the value in [DefaultVal] should be overwritten or a new one should be created. The values in [DefaultVal] will change constantly and can be the same so I cannot pull the data based on that column.</p>
</blockquote>
<p>I need specific values in [DefaultVal] to be on the same row based on the [FormName] and in different columns based on the [ControlName]. <em>The table "Analysis" must be able to update information from "Defaults" and add new such.</em></p>
<p>This is how I would picture the Query:</p>
<blockquote>
<p><strong>General Functions:</strong> The query can identify if there are new rows in [Defaults] and add them according to the below logic. The query can identify if some of the values in [Defaults] have changes and updates them accordingly.</p>
<blockquote>
<p><strong>Data:</strong> Text1, Text2, Text3, Text4, Text5, Text6 and Text7 exist in [Defaults] as [ControlName]. They all have some value in [DefaultVal]. They are all part of the form "Sample" [FormName]. So their [FormName]|[ControlName]|[DefaultVal] would look like this in the columns <code>Sample|Text1|Value</code>; <code>Sample|Text2|Value2</code> etc;;; There is also another set of Text1-7 [ControlName]s, but with a different [FormName]. The values in [DefaultValue] can be the same or different.</p>
<blockquote>
<p><strong>Rule:</strong> The query knows that the [DefaultVal] value of "Text1" as a [ControlName] needs to go into [Column1] from the table [Analysis]. Text2's value goes to [Column2], Text3 into [Column3] etc.</p>
<blockquote>
<p><strong>Logic:</strong> The query takes both instances of Text1's values and wants to put them in [Column1] of [Analysis]. It seems that they have a different [FormName] so it puts them on different rows. Then it takes both instances of Text2's values, it sees that they have a different [FormName] so it wants to put them on different rows. It sees that both [FormName]s exist in Analysis and puts them on the corresponding rows.</p>
</blockquote>
</blockquote>
</blockquote>
</blockquote>
<p>I'm really sorry if this is too long, I'm guessing it is, but I don't know how to explain it otherwise. I have some basic understanding of SQL queries, but this goes way beyond my understanding and I don't even know what commands to use and where.</p>
<p>Can someone please help? =/</p>

Multiple Clients Broadcasting on Same UDP Socket in C
|
<p>I am implementing some sort of auction. 5 users are connected to the same port using a UDP socket on the same address (<code>INADDR_BROADCAST</code>) and same port (<code>udp_port</code>) assigned previously by <code>server.c</code>. Each of them has 10 seconds to offer a price. If 10s pass, the turn will be passed to the next person. Here is how the socket is initialized:</p>
<pre><code>udp_sockfd = socket(AF_INET, SOCK_DGRAM, 0);
if (udp_sockfd < 0)
error("ERROR opening socket\n");
int broadcast_en = 1, opt_en = 1;
setsockopt(udp_sockfd, SOL_SOCKET, SO_BROADCAST, &broadcast_en, sizeof(broadcast_en)); //set broadcasting
setsockopt(udp_sockfd, SOL_SOCKET, SO_REUSEPORT, &opt_en, sizeof(opt_en));
bc_adr.sin_family = AF_INET;
bc_adr.sin_addr.s_addr = htonl(INADDR_BROADCAST);
bc_adr.sin_port = htons(udp_port);
if (bind(udp_sockfd, (struct sockaddr *) &bc_adr, sizeof(bc_adr)) < 0)
error("ERROR on binding");
printf("I am connected to the UDP Socket now\n\n");
</code></pre>
<p>How I handle the scenario above is with <code>fd_set</code></p>
<pre><code> signal(SIGALRM, sig_handler); //Register signal handler
printf("Auction beginning...\n");
alarm(1);
int mx = -1, ans;
while (1)
{
FD_ZERO(&current_sockets);
FD_SET(udp_sockfd, &current_sockets);
FD_SET(STDIN, &current_sockets); //standard input
if ((select(udp_sockfd + 1, &current_sockets, NULL, NULL, NULL) < 0) && (turn_cnt > 5)) //max_fd is udp_sockfd
perror("ERROR on select");
if (FD_ISSET(STDIN, &current_sockets))
{
bzero(buffer, 255);
fgets(buffer, 255, stdin);
int price = atoi(buffer);
if (price > mx)
{
mx = price;
ans = turn_cnt;
}
bzero(buffer, 255);
strcat(buffer, "Person with turn ");
char c[2] = {turn_cnt + '0', '\0'};
strcat(buffer, c);
strcat(buffer, " offered price ");
char d[10]; //digits of price
int sz = 0;
while (price)
{
d[sz++] = '0' + (price % 10);
price /= 10;
}
char rd[10];
for (int i = sz - 1 ; i >= 0 ; i--)
rd[sz - 1 - i] = d[i];
rd[sz] = '\n';
rd[sz + 1] = '\0';
strcat(buffer, rd);
sendto(udp_sockfd, buffer, strlen(buffer), 0,(struct sockaddr *)&bc_adr, sizeof(struct sockaddr_in));
}
if (FD_ISSET(udp_sockfd, &current_sockets)) //something broadcasted on udp_sockfd
{
bzero(buffer, 255);
socklen_t bc_adr_len = sizeof(bc_adr);
int n = recvfrom(udp_sockfd, buffer, 255, 0, (struct sockaddr *)&bc_adr, &bc_adr_len);
if (n < 0)
error("ERROR on reading broadcasted message\n");
printf("BROADCASTED MESSAGE: %s\n", buffer);
fflush(stdout);
}
if (turn_cnt == 5)
break;
}
printf("The winner is user %d with price offer %d\n", ans, mx);
</code></pre>
<p>There weird thing happening is that, when some user broadcasts its price with some sort of message like: "Person with turn 1 offered price 11" using the <code>sendto()</code> function, this message is not received by the other clients until themselves enter their price. For example here is the terminal output of the 3rd client in the queue when he/she enters his/her price:</p>
<pre><code>I am connected to the UDP Socket now
Auction beginning...
Person number 1 in queue has 10 seconds to offer his/her price...
Time is up!
Person number 2 in queue has 10 seconds to offer his/her price...
Time is up!
Person number 3 in queue has 10 seconds to offer his/her price...
22
BROADCASTED MESSAGE: Person with turn 1 offered price 11
BROADCASTED MESSAGE: Person with turn 2 offered price 43
BROADCASTED MESSAGE: Person with turn 3 offered price 22
</code></pre>
<p>The lines starting with "BROADCASTED MESSAGE" corresponding the first and second client, are not being printed on time. They are being printed only when the third client has entered his/her offer which is 22.</p>
<p>The output terminal for the second client is like this:</p>
<pre><code>I am connected to the UDP Socket now
Auction beginning...
Person number 1 in queue has 10 seconds to offer his/her price...
Time is up!
Person number 2 in queue has 10 seconds to offer his/her price...
43
BROADCASTED MESSAGE: Person with turn 1 offered price 11
BROADCASTED MESSAGE: Person with turn 2 offered price 43
</code></pre>
<p>Again it can be seen that the first BROADCAST MESSAGE is not being printed on time.</p>
<p>I have been working on this for two days now and I seriously have no idea why isn't the <code>sendto()</code> method being detected by the other clients on-time. Could someone please help me with this? I would like to have the message (price offer) broadcasted for ALL clients simultaneously so they could see what other prices has been offered before their turn.</p>
<p><strong>Edit</strong>: I have edited some parts of my code as Remy Lebeau said in the comments:</p>
<pre><code> struct sockaddr_in bc_adr_sendto, bc_adr_recvfrom;
bc_adr_recvfrom.sin_family = AF_INET;
bc_adr_recvfrom.sin_addr.s_addr = htonl(INADDR_ANY);
bc_adr_recvfrom.sin_port = htons(udp_port);
bc_adr_sendto.sin_family = AF_INET;
bc_adr_sendto.sin_addr.s_addr = htonl(INADDR_BROADCAST);
bc_adr_sendto.sin_port = htons(udp_port);
if (bind(udp_sockfd, (struct sockaddr *) &bc_adr_recvfrom, sizeof(bc_adr_recvfrom)) < 0)
error("ERROR on binding");
...
sendto(udp_sockfd, buffer, strlen(buffer), 0,(struct sockaddr *)&bc_adr_sendto, sizeof(struct sockaddr_in));
...
socklen_t bc_adr_len = sizeof(bc_adr_recvfrom);
int n = recvfrom(udp_sockfd, buffer, 255, 0, (struct sockaddr *)&bc_adr_recvfrom, &bc_adr_len);
</code></pre>
<p>But still there is no difference in the result.</p>
<p><strong>Edit</strong>: Here is the <code>sig_handler</code> used for alarm:</p>
<pre><code>void sig_handler(int signum)
{
if (turn_cnt != 0)
printf("Time is up!\n");
printf("Person number %d in queue has 10 seconds to offer his/her price...\n", ++turn_cnt);
alarm(10);
}
</code></pre>

WebAuthn Relaying Party ID for various Setups
|
<p>I have an Angular 11 Project, which implements a WebAuthn registration. The backend is SpringBoot 2.4</p>
<p>WebAuthn Login should work in two parts of the project, the "main" and the "viewer"
The domain setup is rather complicated:</p>
<h3>Main Project</h3>
<p><em>Urls</em></p>
<ul>
<li>Local: https://localhost:4202</li>
<li>Staging: <a href="https://company.com" rel="nofollow noreferrer">https://company.com</a> (local Kubernetes Server)</li>
<li>Prod: <a href="https://company-project.com" rel="nofollow noreferrer">https://company-project.com</a></li>
</ul>
<h3>Viewer Project</h3>
<p><em>Urls</em></p>
<ul>
<li>Local: https://localhost:4200</li>
<li>Staging: <a href="https://viewer.develop.plattform.intra.company.com" rel="nofollow noreferrer">https://viewer.develop.plattform.intra.company.com</a> (local Kubernetes Server)</li>
<li>Prod: <a href="https://viewer.company-project.com" rel="nofollow noreferrer">https://viewer.company-project.com</a></li>
</ul>
<h3>Code</h3>
<p><em>environment.ts</em></p>
<pre><code>prodUrls: ['company-project.com'],
webauthn: {
name: "Company DEV",
rpId: "localhost"
}
</code></pre>
<p><em>environment.prod.ts</em> (replace in build)</p>
<pre><code>prodUrls: ['company-project.com'],
webauthn: {
name: "Company Prod",
rpId: "plattform.intra.company.com" // gets overridden by values in "prodUrls"
}
</code></pre>
<p><em>webauthn.service.ts</em></p>
<pre><code>private _getRelyingPartyInfo(): RelyingParty {
let rpId = environment.webauthn.rpId;
/**
* Check if the Hostname matches one of our Prod Hostnames
* and use this instead
*/
environment.prodUrls.forEach((url, index) => {
if (location.hostname.indexOf(url) > -1) {
rpId = environment.prodUrls[index];
}
});
const rp = {
id: rpId,
name: environment.webauthn.name
};
return rp;
}
</code></pre>
<h3>The Issues</h3>
<ul>
<li>It works locally, using the rpId <code>localhost</code> (both Backend and Frontend locally)</li>
<li>It does NOT work on staging --> Backend throws</li>
</ul>
<blockquote>
<p>WebAuthnException message: rpIdHash doesn't match the hash of preconfigured rpId.</p>
</blockquote>
<ul>
<li>It <em>should</em> work on Prod using <code>company-project.com</code> as rpId (scared to deploy as it does not work on staging)</li>
</ul>
<h3>What I tried</h3>
<p>For staging, I changed the rpId to <code>develop.plattform.intra.company.com</code> and I can register and login in "main". Logging in on "viewer" throws an error as well</p>
<p>The spec is not very specific about what should work: <a href="https://www.w3.org/TR/webauthn/#relying-party-identifier" rel="nofollow noreferrer">https://www.w3.org/TR/webauthn/#relying-party-identifier</a>, it only says what shouldn't work. I assume, that the multiple subdomains complicate things on staging?</p>
<p>What would be the correct rpId for staging and is the assumption that <code>company-project.com</code> as rpId should work on prod correct?</p>

WSO2 VFS FTP Proxy does not read parameters
|
<p>I have written a proxy service and deployed on WSO2 ESB 5 to receive some file content via http and use vfs transport to transfer that content to an ftp server. The service works as expected when I specify the connection parameters correctly but when I specify something wrong on the connection string to simulate a down server, I can not manage to control the behavior of the VFS transport using the parameters specified in [1]. What I'm looking for is to short the delay between the error occurred in VFS and the fault exception catched by Axis; </p>
<p>As you are going to see below I specify 0 retries and 0 wait time between retries but it seems the VFSTransportSender class is not able to read somehow those values because it does all the time the same number of retries and it waits the same number of seconds each time it is executed, I also changed the values and put others but the result is always the same, the server is always retrying 3 more times with 30 seconds delay between each other besides the original request before Axis is able to receive some information related to the error.</p>
<p>Here is my proxy service that works without any issues:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>

<p>And when I want to simulate the server is not reachable I just modify the address URI and I put this one where the user is incorrect:</p>
<p><code><address uri="vfs:ftp://ja8irof_ftp:passftp@localhost:21"></code></p>
<p>I have also tried to set the transport.vfs parameters as properties before calling the endpoint but the result is exactly the same</p>

JavaScript get a String from a specific charackter to a space

<p>i have a shoutbox and want to a username highlighting in the messages. The Shoutbox look like this:</p>
<pre><code><dl id="sbPosts">
<dt data-id="1780530" data-user="username">
<a href="user/username" class="user">username</a>
<time>00:00:00</time>

<dd data-id="1780530" data-user="username">
@username text without highlight

<dd data-id="1780530" data-user="username">
@username text without highlight
</dd>
</dl>
</code></pre>
<p>I only want to highlight the "@" and the text after this to the first space like this: "<strong>@skuhlight</strong> whats your question?"</p>
<p>In the shoutbox i want to add a span around the username like this:</p>
<pre><code><dd data-id="1780530" data-user="username">
<span class="highlight">@username</span> text without highlight
</dd>
</code></pre>
<p>Here is the code i tried...</p>
<pre><code> function highlight(username) {
var element = $('#sbPosts > dd');
var rgxp = new RegExp(username, '@');
var res = str.substr(username, ' ');
var repl = '<dd><span class="highlight">' + username + '</span>';
element.html(element.html().replace(username, repl));
}

Problems with strtok()
|
<p>I have been wrestling with this for a while. I know it's a lot of code to look at, but I have no idea where the problem lies and can't seem to narrow it down. I will bounty it.</p>
<p>I wrote this class to parse bbcodes. It uses strtok() primarily, and the class works great unless you put two tags right next to each other, and I can't for the life of me figure out why.</p>
<p>For instance <code>[b] [i]test1[/i] [/b]</code> results in <code><strong> <em>test1</em> </strong></code>.
Yet <code>[b][i]test1[/i][/b]</code> results in <code><strong>i]test1/b]</strong></code>.
The last <code></strong></code> tag is only in there because the parser automatically closes tags it could not find a closing tag for in the string. It somehow misses the <code>[i]</code> and <code>[/b]</code> tags completely.</p>
<p>Here's the class as well as the one subclass it uses for setting up the various bbcodes. The subclass is basically just a data structure with no behaviours.</p>

add two images and one Label in TabBar, SwiftUI
|
<p>I have to implement a custom tabbar. I have attached the UI of required TabBar.</p>
<p><a href="https://i.stack.imgur.com/UKBD8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UKBD8.png" alt="TabBar Image" /></a></p>
<p>I need to add two image inside the each TabBar Item. First one is above the text and second one is at bottom of text. I have tried 3 different method but each time TabBar is showing the same result.</p>
<pre><code> // method one not working
HideNavbarOf(view: HomeView())
.tabItem {
ZStack {
Image(ImageName.diamondFill.rawValue)
.resizable()
.scaledToFit()
.frame(width: 25)
Text("Subscription")
.font(.custom(Popins.regular.rawValue, size: 11))
.foregroundColor(.white)
Image(ImageName.tapSelected.rawValue)
.resizable()
.scaledToFit()
.frame(width: 25)
}
}
.tag(0)
// method two not working
HideNavbarOf(view: Text("AskQuestion"))
.tabItem {
ZStack {
Label {
Text("Shop")
.font(.custom(Popins.regular.rawValue, size: 11))
.foregroundColor(.white)
} icon: {
Image(ImageName.storeLine.rawValue)
.resizable()
.scaledToFit()
.frame(width: 10, height: 10)
}
Image(ImageName.tapSelected.rawValue)
.resizable()
.scaledToFit()
.frame(width: 10, height: 10)
}
}
.tag(1)
// method three not working
HideNavbarOf(view: Text("Chat"))
.tabItem {
Label {
Text("Home")
.font(.custom(Popins.regular.rawValue, size: 11))
.foregroundColor(.white)
} icon: {
VStack {
Image(ImageName.homeLine.rawValue)
.resizable()
.scaledToFit()
.frame(width: 10, height: 10)
Image(ImageName.tapSelected.rawValue)
.resizable()
.scaledToFit()
.frame(width: 10, height: 10)
}
}
}
.tag(2)
</code></pre>
<p>Below is the image of tabBar Item after these methods. There is no effect of any method, tabItem is only considering the first one Image and Label.</p>
<p><a href="https://i.stack.imgur.com/5E74e.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5E74e.png" alt="Preview" /></a></p>
<p>How Can I achieve the required UI that have Image at top and bottom and a text in middle.</p>

How do you represent different versions of the same entity type (class) in the same UML class diagram?
|
<p>I’m trying to figure out how to model a situation with following properties:</p>
<ul>
<li>there is a set of entity types Ei...Ej and a set of relationship types between those entity types Ri...Rj in the domain;</li>
<li>one can distinguish at least two different versions of those entity and relationship types that are significant to different parts of the system <em>at the same time.</em></li>
</ul>
<p>In the simplest case, those different versions might be “real time data” version and “last approved snapshot” version. In this case, being significant to different parts of the system might translate into following:</p>
<ul>
<li>there are less privileged actors and use cases, that can only work with “last approved snapshot” version;</li>
<li>at the same time there are more privileged actors with the same or different set of use cases, that can work with “real time data ” version;</li>
<li>there are entity types Ex...Ey that either form relationships with entities ei...ej from “last approved snapshot” version or whose constraints reference values of attributes of entities ei...ej from “last approved snapshot” version;</li>
<li>at the same time there are different entity types Ea...Eb that either form relationships with entities ei...ej from “real time data” version or whose constraints reference values of attributes of entities ei...ej from “real time data” version.</li>
</ul>
<p>If I want to show all entity types Ei...Ej, Ex...Ey and Ea...Eb from aforementioned example along with their constraints and relationships between them on the same diagram, how would I do that?</p>
<p>I was thinking about using two different classes for the same entity type: one class would represent “last approved snapshot” version of that entity type and another class would represent “real time data ” version of that type.</p>
<p>But I don’t like this approach very much as</p>
<ul>
<li>it seems redundant;</li>
<li>I’m not actually sure what kind of relationship there is between two classes representing two different versions of the same entity type a how to represent that relationship in diagrams (maybe «derive» stereotype from standard profile would be appropriate here, but I'm not sure).</li>
</ul>
<hr />
<p>EDIT</p>
<p>Unfortunately, I can’t use examples from my work, so I’ve come up with this completely fictional one, but one that is also partially modeled after the problem I was trying to solve recently. I’ll be using popular “WorksInUsing” association to pay proper respects. This will make the question more concrete.</p>
<p>Also, to be clear, I’m trying to create conceptual model and not so much OOP/relational design/implementation model.</p>
<p>Let’s assume an entity type Employee.</p>
<p>Let’s assume an actor called “SkillAdministrator” managing following entity and relationship types:</p>
<ul>
<li>entity type Skill</li>
<li>entity type Department</li>
<li>relationship type KnownSkill between entity types Employee and Skill</li>
<li>relationship type WorkInDepatment between entity types Employee and Department</li>
</ul>
<p>Let’s assume, that changes in all those aforementioned entity and relationship types happen rarely but when they do they happen in very large batches and our skill administrator needs quite a time to process each such change.</p>
<p>After he’s finished processing the change, he runs PublishChange use case which creates a snapshot of entity and relationship types Skill and KnownSkill and makes that snapshot available to other users of the system.</p>
<p>Let’s now assume an actor called Manager managing following entity and relationship types:</p>
<ul>
<li>entity type Project</li>
<li>relationship type WorksInUsing between entity types Employee, Skill and Project.</li>
</ul>
<p>Only those Skills that existed at the last run of PublishChange use case can play role in WorksInUsing association. Also the pairs KnownSkill are precondition to triplets WorksInUsing, but again only those KnownSkill pairs, that existed at the last run of PublishChange use case.</p>
<p>At the same time Manager is managing WorksInUsing associations, SkillAdministrator can start working on processing the next big change in entity and relationship types that he manages. Manager doesn't see those changes, not until PublishChange use case is run again.</p>
<p>(Depending on the domain, there are multitude of different ways to handle deletion of particular skill or knownskill association by system administrator and then applying those changes - in the simplest case, both types could be assumed as permament, so new instances can be added but existing instances cannot be deleted, for examples laws work this way)</p>

How can i filter array on object in javascript
|
<p>I have an array named <code>files</code>:</p>
<pre><code> files = [
{
id: "1",
title: "aras",
price: 100,
size: 25,
tools: [
"Hammer",
"Zip",
"Line",
"Nexti"
]
},
{
id: "2",
title: "yasio",
price: 150,
size: 30,
tools: [
"Hammer",
"Zip",
]
},
{
id: "3",
title: "janio",
price: 200,
size: 30,
tools: [

},
{
id: "4",
title: "chashio",
price: 400,
size: 35,
tools: [
"Nexti"
]
},
]
</code></pre>
<p>I want to filter this object, for example, to get the array: prices between <code>90</code> to <code>150</code> and sizes between <code>25</code> to <code>40</code> and tools to include <code>Hammer</code> and <code>Zip</code>.
output must be:</p>
<pre><code>{id: "1", title: "aras", price: 100, size: 25,tools:[...]},
{id: "2", title: "aras", price: 150, size: 30,tools:[...]},
{id: "4", title: "aras", price: 90, size: 40,tools:[...]},

Failed to find the class io.confluent.connect.gcs.GcsSinkConnector while starting kafka-gcs confluent connector
|
<p>I am using confluent connector for kafka and Google Cloud Storage(GCS). I installed confluent using:</p>
<p>(I am doing this on Ubuntu 16.04 and all these commands were executed in the home directory.)</p>
<pre><code>curl https://packages.confluent.io/archive/5.0/confluent-5.0.0-2.11.tar.gz | tar xz

<p>I then installed confluent-hub by:</p>
<pre><code>curl http://client.hub.confluent.io/confluent-hub-client-latest.tar.gz | tar xz
</code></pre>
<p>I then installed the kafka-GCS connector using:</p>
<pre><code>confluent-hub install confluentinc/kafka-connect-gcs:5.0.1
</code></pre>
<p>I then export the path using:</p>
<pre><code>export PATH=<insert-path-here>/confluent-5.0.0/bin:$PATH
</code></pre>
<p>I then start confluent using:</p>
<pre><code>confluent start

Elasticsearch Curator
|
<p>I am using ElasticSearch Version 1.7.2. I want to take a snapshot with help of the curator. I followed a link get to know that it gives me an incremental snapshot but I didn't get any incremental snapshot of my index.</p>
<p>I have 1 index <code>test</code> having 50,000 docs. I have taken a snapshot of that index. After inserting 100,000 docs in the same index, I again took a snapshot of that index. But when I check it, it's showing me the same data in both my snapshots.</p>
<p>What's the difference between those? I don't think it is incremental in any way. Please help me out.</p>

Keep an element scrolled to the bottom
|
<p>I am creating a "log" screen that updates periodically in React. To make sure that the latest addition is always in view I would like the element to always be scrolled to the bottom:</p>
<p><a href="https://i.stack.imgur.com/tMXHL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tMXHL.png" alt="Example of what I want to acheive" /></a></p>
<p>I have the overflow working:</p>
<h1>CSS:</h1>
<pre><code>div.log {
height: 200px;
overflow: auto;
}
</code></pre>
<p>And the HTML:</p>
<h1>JSX:</h1>
<pre><code>render() {
return (
<div className="log">
<ul>
{this.props.log.map((log, i) =>
<li key={i}>
{log.message}
</li>
)}
</ul>
</div>
);
}
</code></pre>
<p>Here is my entire component:</p>
<h1>Javascript</h1>
<pre><code>import React from 'react';
export default class Log extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div className="log">
<ul>
{this.props.log.map((log, i) =>
<li key={i}>
{log.message}
</li>
)}
</ul>
</div>
);
}
}
</code></pre>
<p>This all works fine, but doesn't stay scrolled down. I understand that I can use something similar to:</p>
<pre><code> var element = document.getElementByClassName(".log");
element.scrollTop = element.scrollHeight;
</code></pre>
<p>But this only works once, I need to be scrolled to the bottom when the contents of ".log" updates.</p>
<p>Any help is much appreciated.</p>

aio_write() and lio_listio() of POSIX AIO don't work correctly in write operation
|
<p>I'm setting up a asynchronized writer and want operation order on file be guaranteed by that. I use it as writer in another program which read a pcap file. Consider I have already tried to use both linux-aio and POSIX aio in my code seperately, to write pcap file on disk. I need to know are aio_write() and lio_listio() of POSIX AIO guaranteed to be executed in order?</p>
<p>In linux-aio I use iocb structure to represent a single request for write operation. After fixed number of single operation, io_getevents blocks until fixed number completion report.</p>
<pre><code>struct iocb io_cb;
memset(&io_cb, 0, sizeof(io_cb));
io_cb.aio_fildes = file_descriptor;
io_cb.aio_lio_opcode = IOCB_CMD_PWRITE;
io_cb.aio_reqprio = 0;
io_cb.aio_buf = (__u64)(buffer);
io_cb.aio_nbytes = size;
io_cb.aio_offset = 0;
struct iocb* io_cb_pointer = &io_cb;
static int32_t BLOCKS_COUNT = 1;
syscall(SYS_io_submit, io_context, BLOCKS_COUNT, &io_cb_pointer)
write_count++;
if ((write_count == MAX_EVENT_COUNT) || flush == true)//flush is to flush before exit program.
{
struct io_event* events = (struct io_event *)malloc((write_count) * sizeof(struct io_event));
syscall(SYS_io_getevents, io_context, write_count / 2, MAX_EVENT_COUNT, events, NULL)
}
</code></pre>
<p>above piece of code which is writing responsible results in proper pcap output that can be opened by Wireshark.</p>
<p>But my problem is with POSIX aio which seem doesn't guarantee order of operation in execution. The piece of writing code is demonstrated in below:</p>
<pre><code> aiocb_array = calloc(MAX_EVENT_COUNT, sizeof (struct aiocb*));
aiocb_element = calloc(MAX_EVENT_COUNT, sizeof (struct aiocb));
...
struct aiocb** aiocb_array;
struct aiocb* aiocb_element;
...
static size_t pre_nbytes = 0;
static __off_t pre_offset = 24;//Due to pcap header file length
aiocb_element[write_count].aio_fildes = file_descriptor;
aiocb_element[write_count].aio_lio_opcode = LIO_WRITE;
aiocb_element[write_count].aio_reqprio = 0;
aiocb_element[write_count].aio_buf = (void *)(buffer);
aiocb_element[write_count].aio_nbytes = size;
aiocb_element[write_count].aio_offset = pre_nbytes + pre_offset;
pre_nbytes = size;
pre_offset = aiocb_element[write_count].aio_offset;
aiocb_array[write_count] = &aiocb_element[write_count];
write_count++;
if ((write_count == MAX_EVENT_COUNT) || flush == true )//flush is to flush before exit program.
{
if(flush)
{
if(lio_listio(LIO_WAIT, aiocb_array, write_count, NULL) != 0)
{
printf("Flush lio_listio errno :%d\n", errno);
input->error_code = errno;
return false;
}
}
else
{
if(lio_listio(LIO_NOWAIT, aiocb_array, write_count, NULL) != 0)
{
printf("lio_listio errno :%d\n", errno);
input->error_code = errno;
return false;
}
}
if(write_count == MAX_EVENT_COUNT)
write_count = 0;
}
</code></pre>
<p>As clear in above code, I prepare write request in aiocb structure and assign it's offset, because the file that is used to write was opened without append mode. the piece of code generates pcap file that has same byte like input pcap but unfortunately Wireshark can't open it and show error that indicate:"The capture file appears to be damaged or corrupt. (pcap: File has .......-byte packet, bigger than maximum 0f 65535)". But when I call lio_listio with LIO_WAIT mode and set MAX_EVENT_COUNT = 1, it generates proper pcap output that can be opened by Wireshark correctly.</p>
<p>In addition when I replace lio_listio with aio_write function of POSIX, it produces corrupted file again.
According to mentioned condition which results in proper output pcap, it seems that lio_listio and aio_write function of POSIX execution order are different with program submit order!!!
Does it carried out the operations in arbitrary order? if the answer is yes why it ignore offset value and proper output are not generated? why linux-aio guarantee and keep operation order?
if the answer is no so what is my code and logic problem?</p>
<p>Any help will be appreciated.</p>

XPath Exclude nodes based on attributes of multiple other nodes
|
<p>I'm trying to write XPath against the XML below that will get me all nodes in the list with @id='ResponseActionList' for a specific @rsp_cd where the @act_cd does not exist in the list with @id='ActExcludeList'</p>

<listRow act_cd="A2"/>
<listRow act_cd="A3"/>
</list>
</static>
</cmd-resp>

<p>I can easily get all the nodes containing the appropriate @rsp_cd with this:</p>
<pre><code>//static/list[@id='ResponseActionList']/listRow[@rsp_cd='R2']
</code></pre>
<p>And I can exclude nodes for a particular @act_cd with this:</p>
<pre><code>//static/list[@id='ResponseActionList']/listRow[@rsp_cd='R2' and @act_cd!='A2']
</code></pre>
<p>What I want is to exclude all nodes from the first expression above where the @act_cd attribute is not in the results of this expression:</p>
<pre><code>//static/list[@id='ActExcludeList']/listRow/@act_cd
</code></pre>
<p>I tried something like this, which I didn't expect to work, and I'm not sure what to try next:</p>
<pre><code>//static/list[@id='ResponseActionList']/listRow[@rsp_cd='R2' and not(contains(//static/list[@id='ActExcludeList']/listRow/@act_cd,@act_cd))]
</code></pre>

Python : http.server.HTTPServer : How to close ALL opened files?
|
<p>So basically, I am making an HTTP webhooks server in Python 3 and wanted to add a restart function because shell access is very limited on the server it will be running on.</p>
<p>I found this snippet somewhere on Stack Overflow earlier:</p>
<pre><code>def restart_program():
"""Restarts the current program, with file objects and descriptors
cleanup
"""
try:
p = psutil.Process(os.getpid())
fds = p.open_files() + p.connections()
print (fds)
for handler in fds:
os.close(handler.fd)
except Exception as e:
logging.error(e)
python = sys.executable
os.execl(python, python, *sys.argv)
</code></pre>
<p>For the most part, it works, but I wanted to make sure so I ran a few tests with <code>lsof</code> and found that every time I restarted the server, two more lines (files) were added to the list of open files:</p>
<pre><code>python3 13923 darwin 5u systm 0x18cd0c0bebdcbfd7 0t0 [ctl com.apple.netsrc id 9 unit 36]
python3 13923 darwin 6u unix 0x18cd0c0beb8fc95f 0t0 ->0x18cd0c0beb8fbcdf
</code></pre>
<p>(the adresses varying each restart)</p>
<p>These are only present when I initiate <code>httpd = ThreadingSimpleServer((host, port), Handler)</code>. But even after I call <code>httpd.server_close()</code> these open files persist and psutil doesn't seem to find them.</p>
<p>This isn't really required feature. If this proves to be too much overhead I can drop it, but right now I am only interested in why my code doesn't work and a solution for my own sanity.</p>
<p>Thanks in advance!</p>
<p><strong>UPDATE</strong>:</p>
<p>Changing <code>p.connections()</code> to <code>p.connections(kind='all')</code> got me the <code>unix</code> type fd. Still not sure how to close the <code>systm</code> type fd. Turns out the <code>unix</code> fd had to do with DNS...</p>
<p><strong>UPDATE</strong>:</p>
<p>Well, it looks like I found a solution, however messy it may be.</p>
<pre><code>class MyFileHandler(object):
"""docstring for MyFileHandler."""
def __init__(self, fd):
super(MyFileHandler, self).__init__()
self.fd = fd
def get_open_systm_files(pid=os.getpid()):
proc = subprocess.Popen(['lsof', '-p', str(pid)], stdout=subprocess.PIPE)
return [MyFileHandler(int(str(l).split(' ')[6][:-1])) for l in proc.stdout.readlines() if b'systm' in l]
def restart_program():
"""Restarts the current program, with file objects and descriptors
cleanup
"""
try:
p = psutil.Process(os.getpid())
fds = p.open_files() + p.connections()
print (fds)
for handler in fds:
os.close(handler.fd)
except Exception as e:
logging.error(e)
python = sys.executable
os.execl(python, python, *sys.argv)
</code></pre>
<p>It's not pretty, but it works.</p>
<p>If anyone could shed some light on what actually is/was going on I would very much like to know.</p>

Getting a value back from a child component after it is routed in ReactJS

Unusual Behavior observed while calling main() in any other function in c++
|
<p>I made a simple program to test whether I am able to call main in any other function like we call different functions in other function.</p>
<p>Therefore, I made a program to generate the maximum number by getting input of 3 numbers from the user. For this I made the function containing if else. Surprisingly (especially for me) it worked. I got that I am keep inputting the numbers then I made another variable to control the inputs. I made it to input 3 times. I got answer from bottom to end and 3 answers are generated.</p>
<pre><code>#include <iostream>
using namespace std;
int main();
void max(int a, int b, int c,int p);
int p = 0;
int main()
{
p++;
int a, b, c;
cout << "\n\n";
cout << "Enter 1st number :\t";
cin >> a;
cout << "Enter 2nd number :\t";
cin >> b;
cout << "Enter 3rd number :\t";
cin >> c;
max(a, b, c, p);
cout << "\n\n\n";
system("pause");
return 0;
}
void max(int a, int b, int c,int p)
{
if (p < 3)
{
main();
}
if (a > b&&a > c)
{
cout << a << " is maximum";
}
else if (b > a&&b > c)
{
cout << b << " is maximum";
}
else
{
cout << c << " is maximum";
}
}
</code></pre>
<p>The output was as follows: -</p>
<pre><code>
Enter 1st number : 12
Enter 2nd number : 14
Enter 3rd number : 15
Enter 1st number : 45
Enter 2nd number : 69
Enter 3rd number : 88
Enter 1st number : 14
Enter 2nd number : 20
Enter 3rd number : 11
20 is maximum
Press any key to continue . . .
88 is maximum
Press any key to continue . . .
15 is maximum
Press any key to continue . . .
</code></pre>
<p>I don't get the logic behind it. I used Visual Studio 2017 for this.</p>

Testing Asynchronous Code (useEffect + fetch) In React Components
|
<p>I'm trying to figure out how to test components that update state using useEffect to make an API call to get data. There are several things I think are important to know before I can talk anymore, and that is the files/packages I'm using.</p>
<p>First, I have a main component called <code>App.tsx</code>, inside <code>App.tsx</code>, inside of useEffect, I make a fetch call to an external API to fetch an array of songs by Queen. I also render out a <code><Song /></code> component using <code>.map</code> to iterate over each song and <code>.filter</code> to filter songs on UI based on text input. I'm using a custom hook. Here is the code I have for that component and its custom hook.</p>
<pre><code>// App.tsx
type ISong = {
id: number;
title: string;
lyrics: string;
album: string;
};
export default function App() {
const { songs, songError } = useSongs();
const { formData, handleFilterSongs } = useForm();
return (
<Paper>
<h1>Queen Songs</h1>
<FilterSongs handleFilterSongs={handleFilterSongs} />
<section>
{songError ? (
<p>Error loading songs...</p>
) : !songs ? (
<>
<p data-testid="loadingText">Loading...</p>
<Loader />
</>
) : (
<Grid container>
{songs
.filter(
(song: ISong) =>
song.title
.toLowerCase()
.includes(formData.filter.toLowerCase()) ||
song.album
.toLowerCase()
.includes(formData.filter.toLowerCase()) ||
song.lyrics
.toLowerCase()
.split(" ")
.join(" ")
.includes(formData.filter.toLowerCase())
)
.map((song: ISong) => (
<Grid key={song.id} item>
<Song song={song} />
</Grid>
))}
</Grid>
)}
</section>
</Paper>
);
}
</code></pre>
<pre><code>// useSongs.tsx
type ISongs = {
id: number;
title: string;
lyrics: string;
album: string;
}[];
type IError = {
message: string;
};
export default function useSongs() {
const [songs, setSongs] = useState<ISongs | null>(null);
const [songError, setSongError] = useState<IError | null>(null);
useEffect(() => {
fetch("https://queen-songs.herokuapp.com/songs")
.then(res => res.json())
.then(songs => setSongs(songs))
.catch(err => setSongError(err));
}, []);
return {songs, songError}
}
</code></pre>
<p>Next up is my App.test.tsx file. I am using <code>react-testing-library</code> and <code>jest-dom/extend-expect</code> for my testing coverage. Here is my testing file code. I've been watching a youtube tutorial on the matter and I've read a bunch of articles, but I still can't figure this out.</p>
<pre><code>// App.test.tsx
import * as rctl from "@testing-library/react";
import "@testing-library/jest-dom/extend-expect";
import App from "./App";
// @ts-ignore
global.fetch = jest.fn(() =>
Promise.resolve({
json: () =>
Promise.resolve({
value: [{title: "title1", album: "album1", lyrics: "asdf", id: 1}, {title: "title2", album: "album2", lyrics: "zxcv", id: 2}, etc...],
}),
})
);
describe.only("The App component should", () => {
it("load songs from an API call after initial render", async () => {
await rctl.act(async () => {
await rctl.render(<App />).debug();
rctl.screen.debug();
});
});
});
</code></pre>
<p>This code gives me the following error message</p>
<pre><code>

<p>I honestly am completely lost here, and I have no idea what to do next. My usual problem-solving skills are not helping, so I figured I'd turn to SO for some help. Thank you for reading through all of this and for any help you may be able to provide.</p>
<p>Edit: I stripped the code of most of the CSS in the snippets to make it slightly more readable, so that is why the screen.debug() log includes some CSS and the code doesn't.</p>

Tracking Control Structures in Java for Static Code Analysis (Available Expressions)
|
<p>I am writing a program in Java that does Available expression Analysis on a given Java Program. I have managed to extract Generate and Kill set. To keep it simple, I am going with a constraint that will only analyze programs that declare ONE VARIABLE IN ONE LINE (The regex expression works for it with declaration and initialization but, the logic for redefinition of variables is still in progress. This is the reason why it won't correctly detect the kill set).</p>
<p>The problem I am facing right now is that how would I track the loops? conditional statements? all the control structures? like While, for, and if-else statements.</p>
<p>Can anyone please help? what to use for this? how to keep track of the paths? Below are the code files.</p>
<p>Any assistance you can provide would be greatly appreciated. Thank you!</p>

Shared Preferences doesn't work with Bottom Navigation Bar
|
<p>I have faced an issue on getting data from Shared Preferences. It works anywhere except for win_loss.dart.</p>
<p>Below is the page pulled up right after user signs in. win_loss is pulled up as a part of home_page.dart (default page of bottom navigation bar). Shared preferences data can't be pulled and assigned to userInfo[] when home_page.dart is viewed. I tried Futurebuilder, which doesn't work.</p>
<p>Please help me :)</p>
<p>Thanks,</p>

Exception while rendering XpsDocument after conversion from FlowDocument

Writing to Docker Filesystem as non-root, non-privileged user
|
<p>I have a node/docker app that runs some scripts, and downloads a file to the docker fs, which is then sent to an FTP server. The file is saved to the filesystem in a folder that resides in the same directory (app/src) as the node scripts, allowing easy access for the scripts to then ftp the file. Currently, the scripts are only able to download the file when the image is run as root user, with the --privileged flag. I want to production-ize this and deploy it (ideally on Heroku). Heroku does not allow images to be run as root afaik.</p>
<p>Changing the user to non-root causes the file to not be downloaded, though the container is built perfectly fine, and the image runs with no errors thrown. Seems to be a permissions issue.</p>
<p>Is there a way I can modify this so that I can run this as non-root user and still get the file into the filesystem? The scripts run a headless chrome browser that crawls a website and clicks a button to download an xls file. ( I have the non-privileged user commented out and root user uncommented here, just so I can switch back and forth when testing)</p>

hibernate - foreign key constraints fails even after child records are deleted prior to the parent records
|
<p>I have Two beans AgeGroupDetails and organizationDetails. We have organizationDetails primary key as a foriegn key in the ageGroupDetails table. I am deleting the ageGroupDetails table recored based on organizationId and then deleting organizationDetails table record based on organizationId. I have checked the logs the delete statement related to the ageGroupDetails deletion is executed,(I think not all rows are deleted, how to make sure all rows are deleted) and while deleting organizationdetails record it is throwing foriegn key constraints fails. I have tried different ways to avoid the problem like setting the flushmode to auto so that one statement gets flushed before another statement gets executed and also tried to flush using entityManager.flush() method but of no use. Some times the delete statement generated by hiberante is not executed and raising an exception. I want a solution in that case also</p>
<p>AgeGroupDetails.java</p>

ConnectionException when running a Oozie workflow
|
<p>When trying to run a Oozie workflow with a Java action, I get the following error.</p>
<pre><code>JA006: Call From sandbox.hortonworks.com/10.0.2.15 to sandbox.hortonworks.com:10020 failed
on connection exception: java.net.ConnectException: Connection refused;
For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
</code></pre>
<p>This is the workflow.xml</p>
<pre><code><workflow-app name="cascading-wordcount" xmlns="uri:oozie:workflow:0.4">

<p></p>
<p>I can't even view the logs related to the job. When I try, it gives </p>
<pre><code>Could not find job job_1453962161829_0005.
Job job_1453962161829_0005 could not be found: HTTPConnectionPool(host='sandbox.hortonworks.com', port=19888): Max retries exceeded with url: /ws/v1/history/mapreduce/jobs/job_1453962161829_0005 (Caused by <class 'socket.error'>: [Errno 111] Connection refused)
</code></pre>
<p>I can run the same jar used here using CLI with the command <code>yarn jar</code>. I'm a novice to these. I fear I might have done a stupid mistake.</p>
<p><strong>EDIT</strong></p>
<p>This is what I get when trying to view the logs through CLI as snies said.</p>
<pre><code>impl.TimelineClientImpl: Timeline service address: http://sandbox.hortonworks.com:8188/ws/v1/timeline/
