How can i use DataTable in the following case?
|
<p>The following html table is created from json data file.
Kindly tell me how can i use DataTable and i also need to refresh the table it means every few seconds the new data comes in the json file so the code should read the new json file and updates it in every few seconds.
The running table which i am trying to initiate with DataTable says no data availabe.
Thanks in advance </p>

UItableView automaticDimension not working with UIStackView
|
<p>I want that my <code>UITableViewCell</code> calculates properly its height so its bottom matches the <code>UIStackView</code> bottom.</p>
<p>I have an understanding that for <code>UITableView.automaticDimension</code> to work you need to set all the vertical constraints of the <code>UITableViewCell</code> so it can calculate its height.</p>
<p>That's what I'm failing to do. I've made a test project in which I made sure of:</p>
<ul>
<li><code>tableView.rowHeight</code> property is set to <code>UITableView.automaticDimension</code>.</li>
<li>To not implement function <code>heightForRowAt</code>.</li>
<li><code>TableViewCell</code> <code>Row Height</code> is set to <code>Automatic</code> in the xib file.</li>
<li>All views are constrained vertically.</li>
<li>To play with <code>UIStackView</code> <code>distribution</code> property.</li>
<li>To set the <code>UIStackView</code> bottom constraint to the <code>superView</code> to <code>Less Than or Equal</code> (with this items are too tiny and with <code>Greater Than or Equal</code>, or <code>Equal</code>, item's height is equal to screen width since they have <code>aspect ratio</code> 1:1</li>
<li>To play with <code>Content Hugging Priority</code> and <code>Content Compression Resistance Priority</code>. In the test all views have default values, for hugging horizontal and vertical 250, and for compression horizontal and vertical 750.</li>
</ul>
<p>The code:</p>
<pre><code>import Foundation
import UIKit
class IBAutomaticDimensionTableViewViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet private weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.rowHeight = UITableView.automaticDimension
tableView.register(
IBAutomaticDimensionTableViewCell.nib,
forCellReuseIdentifier: IBAutomaticDimensionTableViewCell.nibName
)
tableView.delegate = self
tableView.dataSource = self
tableView.reloadData()
// view.layoutIfNeeded() Not working with or without it
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(
withIdentifier: IBAutomaticDimensionTableViewCell.nibName,
for: indexPath
) as! IBAutomaticDimensionTableViewCell
return cell
}
}
</code></pre>
<p>The cell's xib file:
<a href="https://i.stack.imgur.com/vyNt4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vyNt4.png" alt="The cell's xib file" /></a></p>

Unable to extract whole cookie with Python's requests module
|
<p>I want to make crawler for one website that requires login.
I have email and password (sorry but I can not share it)</p>
<p>This is the website:
<a href="https://www.eurekalert.org/" rel="nofollow noreferrer">https://www.eurekalert.org/</a>
When I click on login, it redirects me here:
<a href="https://signin.aaas.org/oxauth/login" rel="nofollow noreferrer">https://signin.aaas.org/oxauth/login</a></p>
<p>First I have done this:</p>
<pre><code>session = requests.session()
r = session.get('https://www.eurekalert.org/')
cookies = r.cookies.get_dict()
#cookies = cookies['PHPSESSID']
print("COOKIE eurekalert", cookies)
</code></pre>
<p>The only cookie that I could get is:</p>
<pre><code>{'PHPSESSID': 'vd2jp35ss5d0sm0i5em5k9hsca'}
</code></pre>
<p>But for logging in I need more cookie key-value pairs.</p>
<p>I have managed to log in, but for logging in I need to have cookie data, and I can not retrieve it:</p>

ContextMenuStrip does not appear when clicking on object within a UserControl
|
<p>I created a UserControl with a chart inside that are the same size.
In my main form I create these UserControls dynamically and I can delete or edit them using a ContextMenuStrip by right clicking.</p>
<p>The problem happens when I create dynamically and click on the UserControl above the chart (inside UserControl) the ContextMenuStrip does not appear, it appears only when I click on the <code>userform</code>.</p>
<p>I tested several alternatives to no avail. Someone would have an idea.</p>
<p>EDIT:</p>
<p><a href="https://i.stack.imgur.com/JrLA2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JrLA2.png" alt="Picture1" /></a></p>
<p>I have a UserControl (dynamically generated that is in blue), which is contained in my main form in green. The UserControl consists of just a chart and internal codes, it has the same size as the UserControl (I moved it to exemplify).</p>
<p>Right-clicking on the UserControl, I open a ContextMenuStrip (which belongs to the main form) that allows you to delete, edit and copy.</p>
<p>However the ContextMenuStrip only appears if I click on the UserControl (gray part), if I click on the chart (yellow part) it does not appear.</p>
<p>EDIT2:</p>
<p>I use this code in the main form</p>
<pre><code>Public Sub add_Control_Click(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs)
Try
If e.Button = MouseButtons.Right Then
Dim cms = New ContextMenuStrip
Dim item1 = cms.Items.Add("Edit")
item1.Tag = 1
AddHandler item1.Click, AddressOf menuEdit
Dim item2 = cms.Items.Add("Delete")
item2.Tag = 2
AddHandler item2.Click, AddressOf menuEdit
Dim item3 = cms.Items.Add("Copy")
item2.Tag = 3
AddHandler item3.Click, AddressOf menuEdit
cms.Show(sender, e.Location)
tempControl = sender
End If
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
Private Sub menuEdit(ByVal sender As Object, ByVal e As EventArgs)
Try
Dim item = CType(sender, ToolStripMenuItem)
Dim selection = CInt(item.Tag)
changedControls = True 'Set changed controls
SalvarToolStripMenuItem.Enabled = True 'Set definition enable
Select Case selection
Case 0
tempCopied = True
copiedControl = tempControl
Case 1
callEditControl(tempControl)
Case 3
If MsgBox("Do you want to remove the item.", vbOKCancel + vbQuestion, "Delete") = vbOK Then
Me.Controls.Remove(tempControl)
End If
End Select

JavaScript add json to existing object
|
<p>I'm struggling with adding JSON to existing objects with Vue.js.
So I have a function that is calculating some variants and it's working well for now, but I would need to change them in order to give correct data to my Laravel backend.</p>
<p>So this is how my array looks like (this array is used to calculate variants)</p>
<pre><code>"attributes":[
{
"title":{
"text":"Size",
"value":"1"
},
"values":[
"Red",
"Green"
]
},
{
"title":{
"text":"Color",
"value":"2"
},
"values":[
"X",
"M"
]
}
]
</code></pre>
<p>And I'm calculating them like this:</p>
<pre><code>addVariant: function () {
const parts = this.form.attributes.map(attribute => attribute.values);
const combinations = parts.reduce((a, b) => a.reduce((r, v) => r.concat(b.map(w => [].concat(v, w))), []));
this.form.variants = combinations;
},
</code></pre>
<p>And the output looks like:</p>
<pre><code>"variants":[
[
"Red",
"X"
],
[
"Red",
"M"
],
[
"Green",
"X"
],
[
"Green",
"M"
]
]
</code></pre>
<p>So this is calculated well, but this variants would need to look like this:</p>
<pre><code>"variants":[
{
"title": "Red/M",
"slug": "prooooo",
"options": [
{
"key": "Color",
"value": "Red"
},
{
"key": "Size",
"value": "M"
}
]
},
{
"title": "Red/X",
"slug": "prooooo",
"options": [
{
"key": "Color",
"value": "Red"
},
{
"key": "Size",
"value": "X"
}
]
}
</code></pre>
<p>As you see I have a title field that is calculated by options.values, but the real question is how to make that JSON look like the last given JSON.</p>
<p>Any ideas on how to do it?</p>

How to set fixed y-axis values in SAPUI5 VizFrame Column Chart using XMLView?
|
<p>I have created a VizFrame Column Chart in SAPUI5 using oData. Now I need to put fixed values in y-axis (Dimension axis) since I want to show the days of the week on the y-axis, and how many hours worked in which day using the x-axis. Since I use oData date values I got from SAP, I can only show those values, but I want to show all the days in that week.</p>
<ol>
<li>How can I set fixed scale for y-axis, and then fill those values with oData?</li>
<li>I want to show the time of work in the same days to be added, but I get only one value for a day, it does not add up with different data with the same date</li>
<li>I also cannot format the Time value as HH:mm:ss setting, when I try to format like that, it does not show the column data. The formatting works on sap.ui.Table, but not on the VizFrame.</li>
</ol>
<p>My code in XMLView is as follows:</p>
<pre><code>
<viz:VizFrame id="idVizFrame" width="100%" vizType='column' vizProperties="{title: {text: 'Weekly Timesheet Chart'}}">
<viz:dataset>
<viz.data:FlattenedDataset data="{/TasksSet}">
<viz.data:dimensions>
<viz.data:DimensionDefinition name="JobDate" value="{ path: 'JobDate', type: 'sap.ui.model.type.Date', formatOptions: {source: {pattern: 'yyyy-MM-dd'}, pattern: 'dd.MM.yyyy' } }" />
</viz.data:dimensions>
<viz.data:measures>
<viz.data:MeasureDefinition name="Duration"
value="{path: 'Duration', type: 'sap.ui.model.type.Time', formatOptions: {source:{pattern: 'HHmmss'},pattern: 'HH:mm:ss'}} "/>
</viz.data:measures>
</viz.data:FlattenedDataset>
</viz:dataset>
<viz:feeds>
<viz.feeds:FeedItem id='valueAxisFeed' uid="valueAxis" type="Measure" values="Duration"/>
<viz.feeds:FeedItem id='categoryAxisFeed' uid="categoryAxis" type="Dimension" values="JobDate"/>
</viz:feeds>

AJAX not working in django production mode?
|
<p>I've a django app deployed on heroku. In one of the section I asks for feedback and email of the person. If the email is valid email then I just reply Thank you. This is all being done using AJAX from getting values of form to returning thank you. It works fine in developement mode but not in prouction mode. </p>
<p>Here's my 'index.js'</p>
<pre><code>function valid(email)
{
var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
return emailReg.test(email);
}
$(document).on('submit','.Myform',function(e){
e.preventDefault();
$.ajax({
type:'POST',
url:'',
data:{
message:$('#id_message').val(),
email:$('#id_email').val(),
csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val(),
},
success: function() {
let validate = valid($('#id_email').val());
if(validate){
$('.Myform').fadeOut();
$('.thank_you').fadeIn();
}
else{
$('.Myform').show();
alert('Please enter valid email address.');
}
}
});
});
</code></pre>
<p>I've only one view in my app. So transferring data of AJAX to that view.</p>
<p>Here's my <code>views.py</code></p>
<pre><code>def index(request):
if request.method == 'POST':
form = FeedbackForm(request.POST)
if form.is_valid():
message = request.POST['message']
email = request.POST['email']
print(message)
print(email)
subject = "{} by {}".format(message,email)
recipients = ['xyz@mail.com']
sender = 'my@mail.com'
send_mail(subject, message, sender ,recipients,fail_silently=False)
return HttpResponse('')
else:
form = ThoughtForm()
return render(request,'my_webapp/index.html',{'form':form})
</code></pre>
<p>My <code>urls.py</code> file-</p>
<pre><code>urlpatterns = [
path('',views.index,name='index')
]
</code></pre>
<p>In developement mode- It all works well. </p>
<p><strong>In production mode as soon as I hit submit button it shows me the loading gif but then it dissappears with no thank you message, no wrong email alert nothing happens and form vanishes</strong> </p>
<p>The issue seems to be with the url. Can somebody help.</p>
<p>Here's the traceback error I'm getting in heroku logs-</p>

Multibutton form doesn't map data back to textboxes .net core 1.1
|
<p>Ok, so now I'm trying to learn .net core mcv and I'm having a problem mapping data from MySQL back to my form. When I make the form as a single text box with a single button, and the other fields outside the form (but on the same page), the mapping works fine. If I include all the fields within the form, the data is obtained but not displayed on the page. I have even gone so far as to code one of the multiple submit buttons as an update of the data. I use the first text box to get the item from the database, which it does (but does not map to the text-boxes), then in the second text box (which should have the existing data, but is empty) I put the information to update in the database, click on the submit button for that text box, and the database is updated (but the text boxes in the view remain blank).</p>
<p>My model:</p>
<pre><code> using System;
namespace DbTest.Models
{
public class ProductInventory
{
public string Field1 { get; set; }
public string Field2 { get; set; }
public string Field3 { get; set; }
public int Field4 { get; set; }
}
}
</code></pre>
<p>my controller:</p>
<pre><code>using System;
using Microsoft.AspNetCore.Mvc;
using MySql.Data.MySqlClient;
using Microsoft.AspNetCore.Authorization;
using DbTest.Models;
namespace DbTest.Controllers
{
public class InventoryController : Controller
{
// [Authorize]
public IActionResult Index()
{
return View();
}
[HttpPost]
public IActionResult ProcessForm(string button, ProductInventory p)
{
IActionResult toDo = null;
if (button == "Button1")
{
toDo = GetItem(p);
}
if (button == "Button2")
{
toDo = UpdateField2(p);
}
if (button == "Button3")
{
toDo = UpdateField3(p);
}
if (button == "Button4")
{
toDo = UpdateField4(p);
}
return toDo;
}
// [HttpPost]
public IActionResult GetItem(ProductInventory p)
{
//CODE SNIP - DATABASE QUERY, IT ALL WORKS, SO WHY BOTHER YOU WITH THE DETAILS?
return View("Index", p);
}
public IActionResult UpdateField2(ProductInventory p)
{
//CODE SNIP - DATABASE UPDATE, ALL WORKS, NOTHING TO SEE HERE
return View("Index", p);
}
}
}
</code></pre>
<p>And finally, my view:</p>
<pre><code>@model DbTest.Models.ProductInventory
@{
ViewData["Title"] = "Inventory Page";
}
@using (Html.BeginForm("ProcessForm", "Inventory", FormMethod.Post))
{
<div>
Search Item (Field 1):
@Html.TextBoxFor(model => model.Field1)
<input type="submit" name="button" value="Button1" />
</div>
<div>
Field 2:
@Html.TextBoxFor(model => model.Field2)
<input type="submit" name="button" value="Button2" />
</div>
<div>
Field 3:
@Html.TextBoxFor(model => model.Field3)
<input type="submit" name="button" value="Button3" />
</div>
<div>
Field 4:
@Html.TextBoxFor(model => model.Field4)
<input type="submit" name="button" value="Button4" />
</div>
}
</code></pre>
<p>To reiterate, if I close the form after Button1:</p>
<pre><code>@using (Html.BeginForm("ProcessForm", "Inventory", FormMethod.Post))
{
<div>
Search Item (Field 1):
@Html.TextBoxFor(model => model.Field1)
<input type="submit" name="button" value="Button1" />
</div>
}
<div>
Field 2:
//etc.
</code></pre>
<p>the mapping works, but only the first field and button of the form work. With the form around all four fields and buttons, the mapping doesn't work, but the coding of the second button DOES update the database on clicking Button2.</p>
<p>Can someone explain what I've done wrong here?</p>
<p>Thanks!</p>

Getting ClassNotFoundException on standard PMD cyclomatic complexity plug-in
|
<p>I'm using PMD version 6.20.0 on Windows 10, and I'm attempting to use the cyclomatic complexity plug-in on what I would consider simple Java code just to see if things work. I have a single .java file, CCExample.java, with the code as follows (provided just so everyone can see the source file I'm using, versus asking for comments on the below code which I know is inefficient and only for purposes of an example in an engineering talk I'm giving):</p>
<pre><code>import java.io.*;
import java.math.*;
import java.security.*;
import java.text.*;
import java.util.*;
import java.util.concurrent.*;
import java.util.regex.*;
public class CCExample
{
public static String reduceString(String s, int index)
{
int lastIndex = s.length() - 1;
if (s.length() == 0)
{
return "Empty String";
}
else if (index >= lastIndex)
{
if (isReduced(s, 0))
{
return s;
}
else
{
return reduceString(s, 0);
}
}
else if (s.charAt(index) == s.charAt(index + 1))
{
if (index + 1 < lastIndex)

}
else

System.out.println(reduceString(s, 0));

</code></pre>
<p>With this above single .java file I run the following PMD command:</p>
<pre><code>pmd -d CCExample.java -debug -R category/java/design.xml/CyclomaticComplexity -f text
</code></pre>
<p>In the debug log I get the following:</p>

<p>What am I doing wrong that it cannot find class CCExample? Some .java files I have I get a cyclomatic complexity numbers, others I get the above error. Is there some formatting I'm not doing correctly?</p>

<p>I am trying to create local notification that's declenche before a given date by 2 hours , 4 hours and at this given date. This is my code, but it doesn't work:</p>
<pre><code>private void alarmnotification(String notificationid, String type, long timemills) {

for(int i = 0; i < 4; ++i)
{
long timemfills = timemills - 7200000*i ;
Calendar calendadr = Calendar.getInstance();
calendadr.setTimeInMillis(timemfills);
Calendar calendad0r = Calendar.getInstance();
calendad0r.setTimeInMillis(SystemClock.elapsedRealtime()+calendadr.getTimeInMillis());
Intent intent = new Intent(getApplicationContext(), NotificationPublisher.class);
intent.putExtra("type", type);
intent.putExtra("notificationId", notificationid);
PendingIntent pendingIntent = PendingIntent.getBroadcast(Home.this, i, intent, 0);
mgrAlarm.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, timemfills, pendingIntent);
intentArrayd.add(pendingIntent);

<p>And this is My notification Publisher Code :

public static String NOTIFICATION = "type";
private LocalBroadcastManager broadcaster;
public void onReceive(Context context, Intent intent) {

String message = intent.getStringExtra("type");
// When notification is tapped, call MainActivity.
Intent mainIntent = new Intent(context, Home.class);

mainIntent.putExtra("element_id", notificationId);
mainIntent.setAction(Long.toString(System.currentTimeMillis()));
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, mainIntent, 0);
NotificationManager myNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Prepare notification.
Notification.Builder builder = new Notification.Builder(context);

Closing dialog if post request is sucessful
|
<p>I am using React, Redux, NodeJS, and ExpressJS. I am also using material-ui for the front-end. I have created a dialog where users can input information and signup. Once a user clicks submit, a post req is made. Any errors that are returned would be than put into the errors object in the state. If any errors are returned (ex. passwords don't match) they are stated below the input field. If the submit button is clicked and there are no errors, the dialog stays open. How would I make the dialog be closed if there are no errors returned (the state.open should be turned to false). How would I do this. Here is my code:</p>
<p>authActions.js:</p>
<pre><code>export const registerUser = (userData, history) => dispatch => {
axios
.post("/api/users/register", userData)
.then(res => history.push("/signup/done"))
.catch(err =>
dispatch({
type: GET_ERRORS,
payload: err.response.data
})
);
};

Creating a stored procedure that loops around multiple values passed in for parameters
|
<p>So i am having a JAVA program call a stored procedure and passing in data from an XML file to parameters set in my stored procedure. I have tried calling the stored procedure from within oracle and they work for single values. Would this stored procedure work even if there were multiple values? Do i need to include some kind of FOR loop to ensure that all of the values are inserted?
Below is my code:</p>
<pre><code>CREATE OR REPLACE PROCEDURE pega_submission_value (
rsubmission_id IN NUMBER,
rvalue_tx IN VARCHAR,
rutc_offset IN NUMBER,
rdata_date IN VARCHAR,
rhr_utc IN VARCHAR,
rhr IN TIMESTAMP,
rhr_num IN NUMBER,
rdata_code IN VARCHAR,
rdata_type IN VARCHAR
) IS
v_value_id value.value_id%TYPE;
BEGIN
NULL;
INSERT INTO value (
value_id,
product_id,
data_source_id,
unit_cd,
value_tx,
utc_offset,
data_date,
hr_utc,
hr,
hr_num,
data_code,
create_dt,
create_user_id
) VALUES (
NULL,
555,
3,
'NA',
rvalue_tx,
rutc_offset,
rdata_date,
rhr_utc,
rhr,
rhr_num,
rdata_code,
SYSDATE,
'15'
) RETURNING value_id INTO v_value_id;
INSERT INTO submission_value (
submission_id,
value_id,
form_field_id,
create_dt,
create_user_id,
modify_dt,
modify_user_id,
effective_dt,
inactive_dt
) VALUES (
rsubmission_id,
v_value_id,
(
SELECT
form_field_id
FROM
form_field
WHERE
form_field_tx = rdata_type
),
SYSDATE,

facebook java ads sdk how to retrieve "delivery, results,result_rate,cost_per_result", and breakdown by day
|
<p>I'm trying to use facebook's java sdk to generate the ads report. I mainly followed the Sample code, using new AdAccount(ad_account_id, context).getInsights() to retrieve data. But for the java sdk I could only retrieve partially data. I'm not sure I'm using the correct API.</p>
<pre><code> import com.facebook.ads.sdk.*;
import java.util.ArrayList;
import java.util.List;
import config.fbreporting.gettyimages.com.Config;
public class Sample_code {
public static void main(String args[]) throws APIException {
String access_token = Config.ACCESS_TOKEN;
String ad_account_id = Config.AD_ACCOUNT_ID;
String app_secret = Config.APP_SECRET;
APIContext context = new APIContext(access_token).enableDebug(true);
List<AdsInsights.EnumBreakdowns> breakdowns = new ArrayList<>();
List<AdsInsights.EnumSummary> summaries = new ArrayList<>();
APINodeList<AdsInsights> adsInsights = new AdAccount(ad_account_id, context)
.getInsights()
.setLevel(AdsInsights.EnumLevel.VALUE_AD)
.setFiltering("[{\"field\":\"impressions\",\"operator\":\"GREATER_THAN\",\"value\":\"0\"}]")
// .setBreakdowns(List<AdsInsights.EnumBreakdowns.VALUE_>)
.setBreakdowns(breakdowns)
.setTimeRange("{\"since\":\"2017-08-13\",\"until\":\"2017-09-12\"}")
.requestField("account_id")
.requestField("account_name")
.requestField("ad_name")
.requestField("adset_id")
.requestField("adset_name")
.requestField("ad_id")
.requestField("actions")
.requestField("unique_clicks")
.requestField("unique_inline_link_clicks")
.requestField("impressions")
.requestField("reach")
.requestField("relevance_score")
.requestField("campaign_id")
.requestField("campaign_name")
.requestField("total_action_value")
.requestField("social_impressions")
.requestField("spend")
.requestField("total_actions")
.requestField("total_conversion_value")
.requestField("clicks")
.requestField("date_start")
.requestField("date_stop")
// .requestField("delivery")
// .requestField("result_rate")
// .requestField("results")
// .requestField("cost_per_result")
.execute();
}
}
</code></pre>
<p>If I used this way, it would return: </p>
<pre><code>{
"error": {
"message": "(#100) result is not valid for fields param. please check https://developers.facebook.com/docs/marketing-api/reference/ads-insights/ for all valid values",
"type": "OAuthException",
"code": 100,
"fbtrace_id": "ALSFEzwK4YP"
}
}
</code></pre>
<p>delivery
result_rate
results
cost_per_result</p>
<p>Is there anyone know where to get these fields?</p>
<p>Another problem is I cannot set the breakdown by Day. There is no this VALUE in AdsInsights.EnumSummary. </p>

Generating dates between 2 given dates and looping in PL/SQL

I have created a table in Oracle database and based on that table, I have to generate a report to show the number of open bugs from 5/1/2013 through 5/31/2013, and at the end of the report, need to display the maximum number of open bugs on a single day (using PL/SQL anonymous block).

<p>“Open Bugs” - A bug is considered open on a given day if (1) its “REPORTED_DATE” is on or before that day, and (2) its “CLOSED_DATE” is on or after that day (or is unknown (NULL)). For example, we have 5 open bugs on 5/5/2013.</p>
<p>The output of the program should look like the following:</p>
<pre><code>Date Number of Open Bugs
01-MAY-13 0

The maximum number of open bugs on a single day is 9.
There were 9 open bugs on 14-MAY-13.
There were 9 open bugs on 15-MAY-13.
There were 9 open bugs on 25-MAY-13.
</code></pre>
<p>I have searched and found that there is ADD_MONTHS and CONNECT_BY_LEVEL functions that I can use, to generate the list of days in the month and then use a loop to count the open bugs on that particular day of the month, but do not know how to exactly use them. Can someone please help me get started. Thanks in advance.</p>

<p>I can't print the name and score for the user using this code,
and it also does not run. I have tried multiple different things but i still cannot get it to work no matter what i do to try and fix it. the code also will not run and it will not give me any problems or ways to make it run.</p>

Getting null value from API response with Alamofire

<p>I am trying to get response values from an API url using Alamofire. I created a data model and the response is fine but I am getting null for <code>poster_path</code> and <code>release_date</code>. I was wondering how can handle JSON response correctly. here is my code:</p>
<pre><code> let decoder: JSONDecoder = {
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
return decoder
}()
func fetchMovies( completion: @escaping(MovieResponse?, AFError?) -> Void) {
let url = URL(string: "url")!
let params = [:]
AF.request(url, method: .get , parameters: params)
.responseDecodable(of: Data.self, decoder: decoder) { response in
switch response.result {
case .success(let movies):
completion(movies, nil)
case .failure(let error):
completion(nil , error)
}
}
}

MEP System traversal - cannot find BaseEquipment or Openconnector
|
<h2>Intro</h2>
<p>I'm working on a project where I need to traverse though all elements in a MEPSystem from the starting Mechanical Equipment. I found the 2 articles below by Jeremy Tammik which suggest a way to do this:</p>
<ol>
<li><a href="https://thebuildingcoder.typepad.com/blog/2016/06/traversing-and-exporting-all-mep-system-graphs.html" rel="nofollow noreferrer">Traversing and Exporting all MEP System Graphs</a></li>
<li><a href="https://thebuildingcoder.typepad.com/blog/2016/06/store-mep-systems-in-hierarchical-json-graph.html" rel="nofollow noreferrer">MEP System Structure in Hierarchical JSON Graph</a></li>
</ol>
<p>One of the reference I found in this articles in to the GitHub repository for <a href="https://github.com/jeremytammik/TraverseAllSystems" rel="nofollow noreferrer">TraverseAllSystems</a> and found that the release <a href="https://github.com/jeremytammik/TraverseAllSystems/tree/2017.0.0.8" rel="nofollow noreferrer">2017.0.0.8</a> works best for my need to be able to provide the data in a structured json format like below:</p>
MEP System JSON format!
<pre class="lang-json prettyprint-override"><code>{
"id": 392200,
"name": "Mitered Elbows / Taps",
"children": [
{
"id": 392203,
"name": "Standard",
"children": [
{
"id": 392199,
"name": "Mitered Elbows / Taps",
"children": [
{
"id": 386552,
"name": "450 x 200",
"children": []
},
{
"id": 386555,
"name": "450 x 200",
"children": []
}
]
}
]
}
]
}
</code></pre>
<h2>Problem</h2>
<p>Now the problem is that this seems to be working fine in the <a href="https://knowledge.autodesk.com/support/revit/getting-started/caas/CloudHelp/cloudhelp/2022/ENU/Revit-GetStarted/files/GUID-61EF2F22-3A1F-4317-B925-1E85F138BE88-htm.html" rel="nofollow noreferrer">Sample Revit models</a> provided by Autodesk. But when I try this out in my project, I found that its working as expected.</p>
<p>After debugging for quite some time, I found that the <a href="https://github.com/jeremytammik/TraverseAllSystems/blob/2017.0.0.8/TraverseAllSystems/TraversalTree.cs#L400" rel="nofollow noreferrer"><code>m_system.BaseEquipment</code></a> & <a href="https://github.com/jeremytammik/TraverseAllSystems/blob/2017.0.0.8/TraverseAllSystems/TraversalTree.cs#L444" rel="nofollow noreferrer"><code>openConnector</code></a> in the <a href="https://github.com/jeremytammik/TraverseAllSystems/blob/2017.0.0.8/TraverseAllSystems/TraversalTree.cs" rel="nofollow noreferrer"><code>TraversalTree.cs</code></a> class both return null and that's where the code is breaking because its not able to find the starting element which is the Mechanical Equipment. Does anyone know why this is happening and how to solve this?</p>
<p>Below is the starting part of the respective code that is causing this issue:</p>
Code that breaks
<p>m_system.BaseEquipment</p>
<pre class="lang-cs prettyprint-override"><code>private TreeNode GetStartingElementNode()
{
TreeNode startingElementNode = null;
FamilyInstance equipment = m_system.BaseEquipment; // returns null
// ...
</code></pre>
<p>openConnector</p>
<pre class="lang-cs prettyprint-override"><code>private Element GetOwnerOfOpenConnector()
{
Element element = null;
//
// Get an element from the system's terminals
ElementSet elements = m_system.Elements;
foreach (Element ele in elements)
{
element = ele;
break;
}
// Get the open connector recursively
Connector openConnector = GetOpenConnector(element, null); // returns null
return null != openConnector
? openConnector.Owner
: null;
}
</code></pre>

Using Firebase in Gluon-mobile
|
<p>I want to use Firebase Database in the my <strong>Gluon-mobile Project</strong> , after Reading the <a href="https://firebase.google.com/docs/android/setup/" rel="nofollow noreferrer">Firebase Docs</a>.I tried to this make some modifications to the <em>root</em> level <a href="https://bitbucket.org/guru001/firebase_javafx/src/096da91a5eb51cc4502b665ae0a89ff1b2e0863b/build.gradle?at=master&fileviewer=file-view-default" rel="nofollow noreferrer">build.gradle</a> and <em>App</em> level <a href="https://bitbucket.org/guru001/firebase_javafx/src/096da91a5eb51cc4502b665ae0a89ff1b2e0863b/SampleFirebaseApp/build.gradle?at=master&fileviewer=file-view-default" rel="nofollow noreferrer">build.gradle</a> files.<br>Am trying to use <a href="https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjC14yZiJPYAhXELI8KHURbCDsQFggnMAA&url=https%3A%2F%2Ffirebase.google.com%2Fdocs%2Fstorage%2F&usg=AOvVaw1rIkIFnQ-TiCErZxqKVecb" rel="nofollow noreferrer">Firebase storge</a> in my <a href="https://bitbucket.org/guru001/firebase_javafx" rel="nofollow noreferrer">project</a> and Here's what I Tried.<br></p>
<p>Controller class <em><strong>SignupController.java</em></strong> in package <em>com.application.control</em>.</p>
<pre><code> package com.application.control;
public class SignupController implements Initializable

} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
System.out.println("Signup");

</code></pre>
<p>And the <strong><em>FirebaseInit.java</em></strong> which is in <code>android/java/</code> dir and <code>com.application</code> package which performs Initialization of Firebase Storage.</p>
<pre><code> package com.application;

How to Connect to a Time Server JavaScript
|
<p>I am trying to conenct to any external server in order to display server time instead of the machine time in JavaScript.</p>
<p>I have tried reading</p>
<p><a href="https://stackoverflow.com/questions/7015782/how-do-i-use-access-control-allow-origin-does-it-just-go-in-between-the-html-he">How do I use Access-Control-Allow-Origin? Does it just go in between the html head tags?</a>
, <a href="https://stackoverflow.com/questions/13400594/understanding-xmlhttprequest-over-cors-responsetext/13400954#13400954">Understanding XMLHttpRequest over CORS (responseText)</a>
, and <a href="https://stackoverflow.com/questions/10636611/how-does-access-control-allow-origin-header-work">How does Access-Control-Allow-Origin header work?</a>
but am very limited in knowledge for this subject, so am confused on how to implement the suggestions to get access to a server time.</p>
<p>I am still getting the error:</p>
<pre><code>Access to XMLHttpRequest at 'https://www.stackoverflow.com/' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
</code></pre>
<p>And don't know how to fix it. This is the current code that I have:</p>
<p>HTML:</p>
<pre><code><html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Server date/time</title>
<script language="javascript" src="main.js"></script>
</head>
<script language="javascript">
document.write("Server time is: " + date);
</script>
<body>
</body>
</code></pre>
<p>JavaScript:</p>
<pre><code>var xmlHttp;
function serverTime(){
try {
//FF, Opera, Safari, Chrome
xmlHttp = new XMLHttpRequest();
}
catch (err1) {
//IE
try {
xmlHttp = new ActiveXObject('Msxml2.XMLHTTP');
}
catch (err2) {
try {
xmlHttp = new ActiveXObject('Microsoft.XMLHTTP');
}
catch (err3) {
// use CPU time.
alert("Using CPU Time");
}
}
}
xmlHttp.open('HEAD',"https://www.stackoverflow.com",false);
xmlHttp.setRequestHeader("Content-Type", "text/html");
xmlHttp.send('');
return xmlHttp.getResponseHeader("Date");
}
var st = serverTime();
var date = new Date(st);
</code></pre>
<p>Ideas on what I am doing wrong and what I can do to get the server time? Thanks!</p>

How can I create an asp:button iteratively in code behind aspx file?
|
<p>So essentially I am making a "cart" for a website I am doing as an extra side project. In each item in cart, I am attempting to put a button to remove the item from the cart. The issue is, it is not possible to create an asp:button from the code behind. Everything I have read says to make a placeholder or panel and then put a button inside that, but since I wont know how many items the user has in their cart, I cant just put X amount of placeholders in my aspx file.</p>
<p>My aspx code (so far):</p>
<pre><code><asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
<div id="emptyCart" style="text-align: center;" runat="server">
<h1>Your cart is empty!</h1>
</div>
<div id="cart" runat="server">
</div>
</asp:Content>
</code></pre>
<p>My background writing for making the items appear in cart (this would be for just 1 item):</p>
<pre><code> if (cart.InnerHtml == "")
{
cart.InnerHtml = "<div class='jumbotron'>";
}
else
{
cart.InnerHtml += "<div class='jumbotron'>";
}
cart.InnerHtml += "<div style='display:block;'>";
cart.InnerHtml += "<h3 style='display:inline-block'>Featured</h3>";
cart.InnerHtml += "<h4 style = 'display:inline-block; float:right;' > Special title treatment</h4>";
cart.InnerHtml += "</div>";
cart.InnerHtml += "<div>";
cart.InnerHtml += "<h6>With supporting text below as a natural lead-in to additional content.</h6>";
cart.InnerHtml += "<asp:Button id='remove' Text='Remove' runat='server' OnClick='Remove_Click' class='btn btn-primary btn-lg'></asp:Button>";
cart.InnerHtml += "</div>";
cart.InnerHtml += "</div>";
</code></pre>
<p>How can I make an asp:button or an equivalent feature from the code behind when I don't know how many I am going to need?</p>

Making body background fit the entire screen
|
<p>This is likely a very easy question but I've tried all of the solutions posted and none of them seem to work for me. </p>
<p>I would simply like the gradient applied to my <code><body></code> HTML tag to always fit the screen properly. Whenever I view the browser in a smaller resolution such as this, and try to scroll over, the background appears as such. </p>
<p>Furthermore, if I turn off background-repeat, it just gets filled with white.</p>

response after ajax post request in ember
|
<p>I am new to ember .I designed an ember app and integrate the fb login in it and have to send facebook accesstoken to app backend (post request) and fetch the token generated by backend(rails).</p>
<p>My Post request response is:</p>
<pre><code>{
"token":"71fcb8c39dc6449e2ac8e88d21e4d008cf746e16a774aa8755f6be0dbc43849265f9010111986a912fde60de4f76eb5a600ec286b26ea0a865cc7f5cab49330a",
"user":{"role":"unverified"}
}
</code></pre>
<p>and the component is </p>
<pre><code> import Ember from 'ember';
export default Ember.Component.extend({
fb: Ember.inject.service(),
session: Ember.inject.service(),
authenticate: function(accessToken) {
console.log("accesstoken: "+accessToken);
Ember.$.ajax({
url: "http://localhost:3000/v1/sessions/fb_login",
accepts: 'application/json',
data: { token: accessToken},
crossDomain: true,
headers: {

}
});
},
actions: {
fb_login() {
this.get('fb').login().then((response) => {
if (response.status === 'connected') {
let fbToken = response.authResponse.accessToken;
this.authenticate(fbToken);
} else if( response.status === 'not_authorized') {
// code for not authrized
// this.transitionTo('/');
} else {
// code for facebook login
// this.transitionTo('/');
}
}).catch(() => {
// this.sendAction('check','/');
});
},
}
});
</code></pre>
<p>But after ajax call success is never get called to I am unable to get the the response and browser always responds with:</p>
<pre><code>pretender.js:132 XHR finished loading: POST "http://localhost:3000/v1/sessions/fb_login".
</code></pre>
<p>Somebody please explain me how the ajax work in ember for api calls.</p>

PillPool/KellyPool with java arrays
|
<p>I have been trying to work on a Pill Pool program recently, and have experienced some troubles. First off, for those who don't know: Kelly Pool is a form of pool where each player picks three numbered pills at random (1-15), and knock everyone's numbers in without telling them your pills. I first tried to use the Math.random() method to program this, then I realized I would have to use the shuffle() method on an array. Now I still can't get my two JButtons to effectively display 3 numbers from the shuffled array each time I press a button. </p>
<p>Im a bit of a beginner I guess, so Im new with arrays. Ill add detail if this is to vague a problem.</p>
<pre><code> import javax.swing.*;
import java.awt.*;
import java.util.*;
import java.util.Random;
public class Display05 extends JPanel
{

setLayout(new GridLayout(3, 1));
Font f = new Font("Serif", Font.BOLD, 30);
//total = value = 0;
label1 = new JLabel("First Pill: " + v);
label1.setFont(f);
label1.setForeground(Color.blue);

utton.addActionListener(new istener());
add(utton);

private class istener implements ActionListener

<p>I won't include the driver file unless someone thinks it might be useful. It's only like 10 lines of code, and is mostly the same as all my other drivers.
Thanks for any help!</p>

<p>I am trying to incorporate cli generate commands in my angular2 project but it gives me a error</p>
<p>I am using the angular2-webpack-starter from git </p>
<p>You have to be inside an angular-cli project in order to use the generate command.</p>

How to apply events on cloned elements?

<p>Can someone please help me with this?</p>
<p>I am trying to make an ordering system, it's all going good and well, but our adviser pointed out that we need to let the user have an option to order multiple items on one transaction. That messed me up. I googled a lot about JQueries and JScripts, but I've finally hit a dead end.</p>

JQuery(JQueryTest.js) taken from <a href="http://charlie.griefer.com" rel="nofollow">http://charlie.griefer.com</a> and modified a bit. I got a lot of codes for cloning, but this is the only one I managed to get working with my current forms.</p>
<pre><code> $(document).ready(function() {
$('#btnAdd').click(function() {
var num = $('.clonedInput').length; // how many "duplicatable" input fields we currently have
var newNum = new Number(num + 1); // the numeric ID of the new input field being added
// create the new element via clone(), and manipulate it's ID using newNum value
var newElem = $('#input' + num).clone(true, true).attr('id', 'input' + newNum);
// manipulate the name/id values of the input inside the new element
newElem.children(':first').attr('id', 'name' + newNum).attr('name', 'name' + newNum);
// insert the new element after the last "duplicatable" input field
$('#input' + num).after(newElem);
// enable the "remove" button
$('#btnDel').removeAttr('disabled');
// business rule: you can only add 5 names
if (newNum == 5)
$('#btnAdd').attr('disabled','disabled');
});

<strong>I hit a dead end with having the event <code>onchange</code> on <code><select id='product>'</code> to work with the cloned forms too.</strong></p>
<p>I have also tried using <code>clone(true, true)</code> but could not make it work.</p>
<p>I got custom css too, it only contains very basic design, so I will deem it unnecessary to include.</p>
<p>Please note that we were only taught basic HTML -up until forms if I recall, basic PHP, Java, C#, and SQL. This is my first try to code JScripts and JQueries and I am having a hard time which is which.</p>

What drives numerical instability in eigenvalue computations in python?
|
<p>Let's say I have a data matrix X with num_samples = 1600, dim_data = 2, from which I can build a 1600*1600 similarity matrix S using the <a href="https://en.wikipedia.org/wiki/Radial_basis_function_kernel" rel="nofollow noreferrer">rbf kernel</a>. I can normalize each row of the matrix, by multiplying all entries of the row by (1 / sum(entries of the row)). This procedure gives me a (square) <a href="https://en.wikipedia.org/wiki/Stochastic_matrix" rel="nofollow noreferrer">right stochastic matrix</a>, which we expect to have an eigenvalue equal to 1 associated to a constant eigenvector full of 1s.</p>
<p>We can easily check that this is indeed an eigenvector by taking its product with the matrix. However, using <code>scipy.linalg.eig</code> the obtained eigenvector associated to eigenvalue 1 is only piecewise constant.</p>
<p>I have tried <code>scipy.linalg.eig</code> on similarly sized matrices with randomly generated data which I transformed into stochastic matrices and consistently obtained a constant eigenvector associated to eigenvalue 1.</p>
<p>My question is then, what factors may cause numerical instabilities when computing eigenvalues of stochastic matrices using <code>scipy.linalg.eig</code>?</p>
<p>Reproducible example:</p>
<pre><code>def kernel(sigma,X):
"""
param sigma: variance
param X: (num_samples,data_dim)
"""
squared_norm = np.expand_dims(np.sum(X**2,axis=1),axis=1) + np.expand_dims(np.sum(X**2,axis=1),axis=0)-2*np.einsum('ni,mi->nm',X,X)
return np.exp(-0.5*squared_norm/sigma**2)
</code></pre>
<pre><code>def normalize(array):
degrees = []
M = array.shape[0]
for i in range(M):
norm = sum(array[i,:])
degrees.append(norm)
degrees_matrix = np.diag(np.array(degrees))
P = np.matmul(np.linalg.inv(degrees_matrix),array)
return P
</code></pre>
<pre><code>#generate the data
points = np.linspace(0,4*np.pi,1600)

<p>Using the code provided by <a href="https://stackoverflow.com/users/15649230/ahmed-aek">Ahmed AEK</a>, here are some results on the divergence of the obtained eigenvector from the constant eigenvector.</p>
<pre><code>[-1.36116641e-05 -1.36116641e-05 -1.36116641e-05 ... 5.44472888e-06

norm = 0.9999999999999999
max difference = 0.04986484253966891
max difference / element value -3663.3906291852545
</code></pre>
<p>UPDATE:</p>
<p>I have observed that a low value of sigma in the construction of the kernel matrix produces a less sharp decay in the (sorted) eigenvalues. In fact, for sigma=0.05, the first 4 eigenvalues produced by <code>scipy.linalg.eig</code> are rounded up to 1. This may be linked to the imprecision in the eigenvectors. When sigma is increased to 0.5, I do obtain a constant eigenvector.</p>
<p>First 5 eigenvectors in the sigma=0.05 case</p>

Catching DisabledException when using Custom User Checker in Symfony 4.1
|
<p>I've implemented a Custom User Checker in Symfony following <a href="https://symfony.com/doc/current/security/user_checkers.html" rel="nofollow noreferrer">this guide</a>. I need it to perform the additional check of determining if the account trying to log in is active.</p>
<p>Here's my User Checker code:</p>
<pre><code>class UserChecker implements UserCheckerInterface {
public function checkPreAuth(UserInterface $user) {
if (!$user->getUser()->getIsActive()) {
throw new DisabledException("Account is disabled.");
} else {
return;
}
}
public function checkPostAuth(UserInterface $user) {
return;
}
}
</code></pre>
<p>In this case, the <code>$user</code> object that gets passed in by DI, is simply a wrapper (which implements UserInterface) of my User object. My user object has a bool flag of <code>isActive</code>. if <code>getIsActive</code> returns false, my condition negates that, and it should throw the <code>DisabledException</code>.</p>
<p>This is not the behavior I'm seeing, however. If I log in with an active user, I can log in fine. If I log in with a disabled user, it simply returns me back to the log in screen (no exception thrown).</p>
<p>If I change <code>DisabledException</code> to simply <code>Exception</code>, the exception is thrown, but I don't see a spot in my code where I can catch it so that I can show a pretty 'account is disabled' message to the user above the login screen.</p>
<p>I'm assuming that Symfony is catching and swallowing the <code>DisabledException</code> somewhere.</p>
<p>Here is my <code>security.yaml</code>:</p>
<pre><code>security:
providers:
db_provider:
id: database_user_provider
encoders:
App\Utility\Security\DatabaseUser: bcrypt
firewalls:
main:
pattern: ^/
form_login:
provider: db_provider
login_path: login
check_path: process_login
default_target_path: do_some_stuff
use_referer: true
user_checker: App\Utility\Security\UserChecker

- { path: ^/register, roles: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/userRegister, roles: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/, roles: ROLE_USER }
</code></pre>
<p>My question is: Where is that exception being caught / what do I need to override or implement so that I can get a message out to the user?</p>
<p>or</p>
<p>Where can I catch <code>Exception</code> to do the same thing?</p>

Vectorized comparison of values against a set of values

<p>I have a <code>pd.Dataframe</code> with a column that contains a value such as </p>
<pre><code>df.iloc[:10]['occ']

3 8965
4 430

6 4230
7 5620
8 4040
9 4130
</code></pre>
<p>I then have another dataframe with <code>start</code> and <code>end</code> values for different groups. I want to assign groups to the first dataframe based on their <code>occ</code> value.</p>
<pre><code> start end
group
10 10 950
11 1000 3540
12 3600 3655
13 3700 3955
14 4000 4160
</code></pre>
<p>Since these groups are not intersecting, we have a simple bijection. I was planning to for each <code>occ</code> value, take the group-index of the last row that is smaller than the said <code>occ</code> value.</p>
<pre><code>testAgainst = np.repeat(dfGroups['start'].values[np.newaxis, :], repeats=10, axis=0)

<p>And now, since the dimensions are <code>(10,)</code> and <code>(10, 14)</code>, there should automatic broadcasting happening. I am expecting to be able to do</p>

Dynamically loading large data in jTable using SwingWorker
|
<p>In Netbeans, I am trying to create a Desktop Application whose UI looks like below:</p>
<p><a href="https://i.stack.imgur.com/3b0vP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3b0vP.png" alt="enter image description here"></a></p>
<p>I am executing "adb logcat command" through Java code which loads 1000s of lines of logs in few seconds & I intend to display all of this information through jTable in NetBeans. </p>
<p>Using parameter: adb logcat -t 100 -> I am restricting the logs to 100 lines only right now.
However the applet becomes unresponsive (or gets stuck in process() method) for 1000 lines or when removing such restriction on number of lines.</p>
<p>I am not sure whether I have properly implemented the SwingWorker thread in my code. I am looking for suggestions on how to improve the code for loading large amount of data dynamically without applet becoming unresponsive.</p>
<p>Following is the implemented code for the applet... with 2 functions:</p>

<li><p>SwingWorker implementation.</p>
<pre><code> public void viewLogs() throws IOException {
String[] command = {"CMD","/C", "adb logcat -t 100"};

Process process = probuilder.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);

Copying Data to another workbook
|
<p>I use two workbooks (obviously based on the question:)), from the first one (as you will see in the code below) gets sorted by the data in column "B". The data in this column is just a number based on the month (11=November, December=12, etc.). For this question (and it will provide the answer for my other monthly workbooks), need to copy all the rows of data (columns A:AE) in column B to another workbook (which is already open), and paste the data into the empty row at the bottom. I have the sort part working fine. I am trying to add in the copy & paste function into the code, but can't get it to work. HELP!</p>
<p>Here is the code I have tried (but can't figure out how to get focus to the target workbook):</p>
<pre><code>Sub Extract_Sort_1512_December()
' This line renames the worksheet to "Extract"
Application.ScreenUpdating = False
ActiveSheet.Name = "Extract"
' This line autofits the columns C, D, O, and P
Range("C:C,D:D,O:O,P:P").Columns.AutoFit
' This unhides any hidden rows
Cells.EntireRow.Hidden = False
Dim LR As Long
With ActiveWorkbook.Worksheets("Extract").Sort
With .SortFields
.Clear
.Add Key:=Range("B2:B2000"), SortOn:=xlSortOnValues, Order:=xlDescending, DataOption:=xlSortNormal
End With
.SetRange Range("A2:Z2000")
.Apply
End With
For LR = Range("B" & Rows.Count).End(xlUp).Row To 2 Step -1
If Range("B" & LR).Value <> "12" Then
Rows(LR).EntireRow.Hidden = True
End If
Next LR
Cells.WrapText = False
Sheets("Extract").Range("A2").Select
Dim LastRow As Integer, i As Integer, erow As Integer
LastRow = ActiveSheet.Range(“A” & Rows.Count).End(xlUp).Row
For i = 2 To LastRow
If Cells(i, 2) = “12” Then
Range(Cells(i, 1), Cells(i, 31)).Select
Selection.Copy
ActiveWorkbook(“Master File - Swivel - December 2015.xlsm”).Select
Worksheets(“Master”).Select
erow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Row
ActiveSheet.Cells(erow, 1).Select
ActiveSheet.Paste
End If
Next i
Application.ScreenUpdating = True
End Sub
</code></pre>
<p>I have found this code below, but do not know how to insert it properly into my code above. The thing that makes me weary is that the workbooks are already open. The target workbook is located on our SharePoint site and I do not know how (or if) you can use VBA code to open it to your desktop.</p>
<p>Here is the other code:</p>
<pre><code>Sub Demo()
Dim wbSource As Workbook
Dim wbTarget As Workbook
' First open both workbooks :
Set wbSource = Workbooks.Open(" ") ' <<< path to source workbook
Set wbTarget = ActiveWorkbook ' Workbooks.Open(" ") ' <<< path to destination workbook
'Now, transfer values from wbSource to wbTarget:
wbTarget.Sheets("Sheet1").Range("B2").Value = wbSource.Sheets("Sheet3").Range("H4")
wbTarget.Sheets("Sheet1").Range("B3").Value = wbSource.Sheets("Sheet3").Range("J10")
'Close source:
wbSource.Close

gqlgen coding style code is tightly coupled to neo4j golang
|
<p>I am just starting to get used to gqlgen to create a golang based graphql api for a personal project I am working on. This is my first attempt at adding a user node into the db, the code works (it took a while, I am new to go neo4j and graphql).</p>
<p>My problem is it feels very coupled to the db, my coding style would be to abstract away the db operations from this code. I don't feel sufficiently experienced to achieve this so I am looking for advice to improve before heading into further programming. I have 25+ years experience of different languages SQL, C++, PHP, Basic, Java, Javascript, Pascal, etc so happy with programming and databases (not so much graph databases).</p>

Possible Multiple AuthenticationSchemes in request header?
|
<p>I have two webapis A and B. From A i make a request to B. A contains user info from identityserver4 where i just need to pass the token to the request header. Beside identityserver token, A also uses AAD(Azure Active Directory) where i have registred B. So from A, i also check my AAD so that i can retrieve The token from Azure to send to B, This is just so B can trust that a request is coming from a trusted registred source. As you can understand From A i have two tokens, one to check the loged in user and the other to check registred application. My A startup class look like this:</p>
<pre><code>public void ConfigureServices(IServiceCollection services)
{
Config = services.ConfigureAuthConfig<AuthConfig>(Configuration.GetSection("AuthConfig"));
services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddScoped<ICurrentUser, CurrentUser>();
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddIdentityServerAuthentication(//this coming with identityserver token and user info
idt =>
{
idt.Authority = "https://gnoauth.se:5005";
idt.ApiName = "globalnetworkApi";
idt.SaveToken = true;
idt.RequireHttpsMetadata = true;
}
);
</code></pre>
<p>So here is my A httpclienthelper, where i setup my client headers to send to B, As i already have the token and user from identity server so the other thing i do here is to send B authority, client id and secret to AAD for retrieving the second token:</p>
<pre><code>var context = new HttpContextAccessor().HttpContext;
var accessTokenFromIdentityserver = await
context.GetTokenAsync(OpenIdConnectParameterNames.AccessToken);
var tokenfromAAD = result.AccessToken;
defaultRequestHeaders.Authorization = new
AuthenticationHeaderValue("AAD_Authentication", tokenfromAAD);
</code></pre>
<p>from here i actualy have all i need, both the tokens and all claims. As you can see to the defaultrequestheaders i only cansend one token but i would like to send both tokens to B, how can i configure the request headers to be able to do that?</p>
<p>So here is the B startup</p>
<pre><code>services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer("AAD_Authentication", opt =>
{
opt.Audience = Configuration["AAD:ResourceId"];
opt.Authority = $"{Configuration["AAD:InstanceId"]}{Configuration["AAD:TenantId"]}";
opt.RequireHttpsMetadata = true;
})
.AddJwtBearer("IDS4_Authentication",
idt =>
{
idt.Authority = "https://gnoauth.se:5005";
idt.Audience = "globalnetworkApi";
idt.SaveToken = true;
idt.RequireHttpsMetadata = true;
}
);
services.AddAuthorization(options =>
{
options.DefaultPolicy = new AuthorizationPolicyBuilder()
.RequireAuthenticatedUser()
.AddAuthenticationSchemes("AAD_Authentication", "IDS4_Authentication")
.Build();
</code></pre>
<p>But i also setup a policy so that from some of my controllers i need to authorize both logedin user and application registration like this</p>

How to obtain underlying checkbox values in a reactive?
|
<p>I have the following shiny dashboard app, this app currently generates checkboxes from a dataframe which i have created in the server section - there is also a select all button, what i want to do is the following: </p>
<p>1) create a reactive - (there is an example of a commented section in the code where i have attempted this, but it did not work) - this reactive should contain the "id" values of the selected checkbox (so this the values in the first column of the underlying data frame) </p>
<p>2) Make sure that this works for these scenarios - when a user selects checkboxes on their own, and then it also works when a user presses the "select all" button - so this reactive will update and populate itself in either of those situations </p>
<p>I have commented out some code where i attempted this but ran into errors and issues - does anyone know how to actually get those id values for what you select in the checkboxes? this has to work across all tabs and also work if the select all button is pressed or un pressed </p>
<p>code for reference! </p>

p.run()

Why is not the state updated?
|
<p>I have a function that updates a state with a change and adds a value, but the state in the 'addResponse' function does not always change:</p>
<pre><code>handleSelected (e, item) {
this.setState({
current_component_id: item.id,
}, () => this.addResponse()
);
};
</code></pre>
<p>Call function above:</p>
<pre><code>addResponse (e) {
const { enrollment_id, evaluation_id, user_id, question_id, current_component_id,
responses, current_question, current_question_id
} = this.state;
console.log(current_component_id)
if (current_component_id != 0) {
const newResponse = {
enrollment_id: enrollment_id,
evaluation_id: evaluation_id,
user_id: user_id,
question_id: current_question_id,
answer_component: current_component_id,
};
function hasAnswer(res) {
const list_question_id = res.map((item) => {
return item.question_id
});
if (list_question_id.includes(current_question_id)) {
return true
} else {
return false
}
}
if (responses === undefined) {
this.setState({
responses: [newResponse]
}
, () => console.log('---------> primeiro', this.state.responses)
)
} else {
const check = hasAnswer(responses);
if (check) {
this.setState(prevState => {
prevState.responses.map((item, j) => {
if (item.question_id === current_question_id) {
return item.answer_component = current_component_id
}
return item ;
})
}
, () => { console.log('----> questao alterada ', this.state.responses)}
)
} else {
this.setState({
responses: [...this.state.responses, newResponse]
}
, () => console.log('------> questao nova', this.state.responses)
);
}
}
}
// this.nextQuestion();
};
</code></pre>
<p>the first console.log is always correct, but the others do not always change, I know that setState is asyn, but I thought that as I call the addResponse function it would be async</p>

Why is my program repeating itself. Java Error

<p>I am supposed to make the program give the number of pets and the percentage of how many that are below 5lbs, 5-10lbs, and over 10lbs. The program keeps repeating the statements and I don't know why. I've been working on this problem for the past couple of days and I still can't figure it out. At times it seems like I fixed it but then later on it happens again. Can anyone clarify why this is happening? I need help please.</p>

Python dictionary merge values and delete previous
|
<p>I have a dictionary of characters and their position on a page keyed by their y position (so all characters in a row are under a single key in the dictionary). The data comes from a table from a pdf and I am trying to combine the characters in rows into words based on spacing so that columns are separated as values. So this:</p>
<pre><code>380.822: [[u'1', [61.2, 380.822, 65.622, 391.736]],
[u' ', [65.622, 380.822, 67.834, 391.736]],
[u'p', [81.738, 380.822, 83.503, 391.736]],
[u'i', [84.911, 380.822, 89.333, 391.736]],
[u'e', [90.741, 380.822, 95.163, 391.736]],
[u'c', [96.571, 380.822, 100.548, 391.736]],
[u'e', [100.548, 380.822, 104.97, 391.736]],
[u' ', [104.97, 380.822, 107.181, 391.736]],
[u'8', [122.81, 380.822, 127.232, 391.736]],
[u'9', [127.723, 380.822, 132.146, 391.736]],
[u'0', [132.636, 380.822, 137.059, 391.736]],
[u'1', [137.55, 380.822, 141.972, 391.736]],
[u'S', [142.463, 380.822, 146.885, 391.736]],
[u'Y', [147.376, 380.822, 152.681, 391.736]],
[u'R', [153.172, 380.822, 157.595, 391.736]],
[u'8', [157.595, 380.822, 162.017, 391.736]]]
</code></pre>
<p>would become this:</p>
<pre><code>380.822: [[u'1 ', [61.2, 380.822, 67.834, 391.736]],
[u'piece ', [81.738, 380.822, 107.181, 391.736]],
[u'8901SYR8', [122.81, 380.822, 162.017, 391.736]]]
</code></pre>
<p>I thought I could iterate through the values for each key and merge the text and coordinates if the space was less than some value and then delete the value that got merged, but this would throw off the iteration. All the possibilities I come up with are really clunky, such as marking the leftovers from merges with a character to indicate deletion later but my function started merging these as well.</p>
<p>Thanks</p>
<p>@Lattyware, thanks again for your help. I tried implementing your suggestions and they are mostly working, but I think I am not fully grasping the idea of the groupby. Specifically why in your example it did not do a merge without a group change, but it does with my modifications (such as the merge after the 8 in the 8901SYR8)? The result in my code is that some of my lines split the first letter of the string from the rest:</p>
<pre><code>{380.822: [
(u'1 ', [61.2, 380.822, 65.622, 391.736]),
(u'p', [81.738, 380.822, 83.503, 391.736]),
(u'iece ', [84.911, 380.822, 89.333, 391.736]),
(u'8', [122.81, 380.822, 127.232, 391.736]),
(u'901SYR8 ', [127.723, 380.822, 132.146, 391.736]),
(u'M', [172.239, 380.822, 178.864, 391.736]),
(u'ultipurpose Aluminum (Alloy 6061) .125" Thick Sheet, 12"'...]}
</code></pre>
<p>The adaptations I made are:</p>
<pre><code>xtol=7
def xDist(rCur,rPrv):
if rPrv == None: output=False
else: return not rCur[1][0]-rPrv[1][2] < xtol
def split(row):
ret = xDist(row, split.previous)
print "split",ret,row,split.previous
split.previous = row
return ret
split.previous = None
def merge(group):
letters, position_groups = zip(*group)
return "".join(letters), next(iter(position_groups))
def group(value):
return [merge(group) for isspace, group in
itertools.groupby(value, key=split)]
print({key: group(value) for key, value in old.items()})

<p>I return to c++ programming, therefore, I am trying a lot of things to master new c++ standard. I know the code I provided is very bad. I think I know how to fix it. </p>
<p>code:</p>
<pre><code>#include <iostream>
#include <thread>
using namespace std;
void apple (string const& x)
{
cout << "aaa" << endl;
}
void orange()

//string s = "hello";
thread t(apple,"hello");
t.detach();
}
int main() {
orange();
cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
return 0;
}
</code></pre>
<p>one kind of outputs:</p>
<pre><code>!!!Hello World!!!
aaa
aaa
</code></pre>
<p>from the code, we can see the "aaa" should be printed once.
my question is why there are two "aaa" on the output. what cause this problem?</p>
<p>many thanks</p>

according @mark's answer. this is an undefined behavior.<br>
I added a "sleep(1);" before main return. it gives me only one type of output. now i got confused, if it is undefined, why i didnt see other types of output?</p>

How to avoid TP being fired with SL, if TP has not yet been reached?
|
<p>The script sends messages to the broker for each action. Therefore to avoid errors, a TP order can not fire when an SL order does.</p>
<p>I'd be extremely grateful for any concrete examples with the code below, on how to have TP fire only if it reaches target, otherwise have SL close entire (or remaining position) by itself.</p>
<p>I tried various strategy.order combinations but I just can not get my head around this one.</p>
<pre><code>//@version=5

Different font on strong elements for Internet Explorer 11 and Safari on iOS 9
|
<p>I have a web app with two fonts, Amatic SC for <code>h1</code> and <code>h2</code> and Open Sans for the rest. The webpage displays <code>strong</code> text fine on most browsers:</p>
<p><a href="https://i.stack.imgur.com/Q1Cov.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Q1Cov.png" alt="Display on Firefox and most browsers" /></a></p>
<p>For Safari on iOS 9 (tested on iPhone 4S) and Internet Explorer 11 on Windows 8.1 (tested on LambdaTest), the <code>strong</code> elements use the font from the <code>h1</code> and <code>h2</code> elements:</p>
<p><a href="https://i.stack.imgur.com/OU47j.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OU47j.png" alt="Display on iOS 9 Safari and Internet Explorer 11" /></a></p>
<p>The relevant CSS for these elements is:</p>
<pre><code>@font-face {
font-family: 'Amatic SC';
font-style: normal;
font-weight: 400;
src: url(/fonts/amatic-sc-v13-latin-regular.woff2) format('woff2'), url(/fonts/amatic-sc-v13-latin-regular.woff) format('woff'); }
@font-face {

<p>The website is at <a href="http://www.emotionathletes.org" rel="nofollow noreferrer">www.emotionathletes.org</a> if you want to further inspect.</p>
<p>What is the reason for the use of a different font on iOS Safari and Internet Explorer?</p>
<h2>Minimal reproducible example</h2>
<p>Following the comment, I narrowed the issue to the loading of the fonts. If I load them in the <code>head</code> of the HTML, linked to Google Fonts, then the page displays well. If I load them locally in the CSS with <code>@font-face</code> from a <code>woff</code> or <code>woff2</code> file, then the strong elements display with a different font on iOS 9 on iPhone 4S and on Internet Explorer 11 on Windows 8.1. The order of loading the fonts in the CSS does not change the result.</p>
<p>A minimal reproducible example has HTML file <code>strong.html</code>:</p>
<pre><code><!DOCTYPE html>
<html><head>

Spark MapGroupsWithState Update function doesn't allow action queries like filter, count, show etc
|
<p>I have an IoT application where I receive the data from different Energy Meters and Inverter Meters. These meters continuously sends meter value as no of units consumed. This value continuously increments over period of time and I have to calculate One hour Energy Consumption for each meter.</p>
<p>I get all this data in a kafka topic from which I create Structured Streaming Dataframe. </p>
<p>On this expanded dataframe I am applying mapGroupsWithState function. This should return me one hour generation. </p>
<p>The Problem:
I am not able to do any of the count, show, filter, aggregation operations inside update function using spark dataframe.</p>
<pre><code> val df_output = final_df
.selectExpr("*")
.as[input_row_druid]
.groupByKey(_.plant_slug)
.mapGroupsWithState(GroupStateTimeout.ProcessingTimeTimeout)(updateAcrossEvents)
.writeStream
.format("console")
.outputMode("update")
.start()
df_output.awaitTermination()
def updateAcrossEvents(plant_slug:String, inputs: Iterator[input_row_druid],
oldState: GroupState[source_state]):out_state = {
val spark_session = SparkSession.builder().getOrCreate()
import spark_session.implicits._
val list_of_list = inputs.toList
val new_df = list_of_list.toDF
var my_state:source_state = if (oldState.exists) oldState.get else source_state(plant_slug,list_of_list)
println("Printing inverter and merter df with counts")
val inverter_df = new_df.filter($"device_type" === "INVERTER")
val meter_df = new_df.filter($"device_type" === "METER")
println(inverter_df.show())
val inv_count = inverter_df.count()
println(meter_df.show())
val meter_count = meter_df.count()
println(inv_count)
println(meter_count)
val new_state = source_state(plant_slug, list_of_list)
oldState.update(new_state)
var out = out_state(plant_slug,inv_count.toString,meter_count.toString)
out
}
</code></pre>
<p>If I do not do any filter operation new_df.show prints all data in dataframe. But count, show, filter not functioning.</p>
<p>One thing I noticed that is whenever I submit job to spark it runs in multiple batches, batch 0 is always successful but it hangs on batch 0. It never proceeds in next batch.</p>
<p>This is expected Result</p>
<pre><code>+--------------------+-------+---------+
| plant_slug|inv_gen|meter_gen|
+--------------------+-------+---------+
| plant1| 11| 10|
| plant2| 20| 19|
| plant3| 40| 38|
| plant4| 59| 57|
| plant5| 37| 35|

how do i take a generated value and insert into a graph?
|
<p>Hi I'm new to web designing and some of my jargon may be wrong. I'm trying to create a graph for lectures that shows the average rating each lecture gets. I have already calculated the average for each of the 18 lectures. Now I want to take the value for each one and insert it as the value in the graph.</p>
<p>Here is how I query and output my lectures:</p>
<pre class="lang-php prettyprint-override"><code><?php
ini_set('display_errors', 1);
include ('connection.php');
$queryLecture = "SELECT DISTINCT lectureID FROM LectureReview ORDER BY lectureID";
$resultLecture = $mysqli->query($queryLecture);
while ($rowLecture = $resultLecture->fetch_assoc()) {
echo "<div class=\"row\">";
echo "<div class=\"box\">Lecture{$rowLecture['lectureID']}:</div>";
$lectureID = $rowLecture['lectureID'];
$mysqli2 = new mysqli($hostname, $username, $password, $database);
$stmt = $mysqli2->prepare("SELECT AVG( lectureReview ) AS lectureAvg FROM LectureReview WHERE lectureID = ?");
$stmt->bind_param('i', $lectureID);
$stmt->execute();
$stmt->bind_result($lectureAvg);
$stmt->fetch();
echo "<div class=\"box\">Average Lecture Rating: {$lectureAvg}</div>";
echo "</div>";
}
?>
</code></pre>
<p>Then, <code>OnLoad</code> I do this:</p>
<pre class="lang-js prettyprint-override"><code>var chart = new CanvasJS.Chart("chartContainer", {
theme: "theme1",
title:{
text: "Average Lecture Score"
},
animationEnabled: true,
data: [
{
// Change type to "bar", "area", "spline", "pie",etc.
type: "column",
dataPoints: [
{ label: "Lecture 1", y: 4.5 },
{ label: "Lecture 2", y: 4.5 },
{ label: "Lecture 3", y: 5.0 },
{ label: "Lecture 4", y: 5.0 },
{ label: "Lecture 5", y: 5.0 },
{ label: "Lecture 6", y: 5.0 },
{ label: "Lecture 7", y: 5.0 },
{ label: "Lecture 8", y: 5.0 },
{ label: "Lecture 9", y: 5.0 },
{ label: "Lecture 10", y: 5.0 },
{ label: "Lecture 11", y: 5.0 },
{ label: "Lecture 12", y: 5.0 },
{ label: "Lecture 13", y: 5.0 },
{ label: "Lecture 14", y: 5.0 },
{ label: "Lecture 15", y: 5.0 },
{ label: "Lecture 16", y: 5.0 },
{ label: "Lecture 17", y: 5.0 },
{ label: "Lecture 18", y: 5.0 },
]
}
]
});
chart.render();
</code></pre>
<p>And my target container:</p>
<pre class="lang-html prettyprint-override"><code><div id="chartContainer"
style="height: 300px; width: 90%; position: absolute; padding-top:50px;">
</div>

Loading images dynamically using JQuery
|
<p>I have a scenario where I have a user select an image to upload to his/her user profile on my webpage. I'm using .net's MVC3 architecture for my website. What i need is for the image to show on the page after he chooses the one he wants but before i store it in the database. I searched around and ended up trying this which a friend of mine said worked for him:</p>
<p>In the view I tried:</p>
<pre><code><div class="floatRight">
<a onclick="opendialogbox('imageLoad2');" style="cursor: pointer">Photo</a>
<img src="… " width="16" height="16" id="imgThumbnail2" alt="photo" />
<input type="file" name="imageLoad2" accept="image/*" id="imageLoad2" onchange="ChangeImage('imageLoad2','#imgThumbnail2')" hidden="hidden" />
</div>
<script type="text/javascript">
function opendialogbox(inputid) {
document.getElementById(inputid).click();
}
function ChangeImage(fileId, imageId) {
var ext = document.getElementById(fileId).value.match(/\.(.+)$/)[1];
switch (ext.toLowerCase()) {
case 'jpg':
case 'bmp':
case 'png':
case 'gif':
case 'jpeg':
{
var myform = document.createElement("form");
myform.style.display = "none";
myform.action = "/ImagePreview/AjaxSubmit";
myform.enctype = "multipart/form-data";
myform.method = "post";
var imageLoad;
var imageLoadParent;
//test browser used then submit form
$(myform).ajaxSubmit({ success:
function (responseText) {
var d = new Date();
$(imageId)[0].src = "/ImagePreview/ImageLoad?a=" + d.getMilliseconds();
if (document.all || is_chrome)//IE
imageLoadParent.appendChild(myform.firstChild);
else//FF
document.body.removeChild(myform);
}
});
}
break;
default:
alert('Error, please select an image.');
}
}
</script>
</code></pre>
<p>And in the controller i tried:</p>
<pre><code>[AcceptVerbs(HttpVerbs.Post)]
public ActionResult AjaxSubmit(int? id)
{
Session["ContentLength"] = Request.Files[0].ContentLength;
Session["ContentType"] = Request.Files[0].ContentType;
byte[] b = new byte[Request.Files[0].ContentLength];
Request.Files[0].InputStream.Read(b, 0, Request.Files[0].ContentLength);
Session["ContentStream"] = b;
HttpPostedFileBase file = Request.Files[0];
string myFilePath = Server.MapPath(Url.Content("~/Content/themes/base/images/Auxiliar.png"));
file.SaveAs(myFilePath);
return Content(Request.Files[0].ContentType + ";" + Request.Files[0].ContentLength);
}
public ActionResult ImageLoad(int? id)
{
byte[] b = (byte[])Session["ContentStream"];
int length = (int)Session["ContentLength"];
string type = (string)Session["ContentType"];
Response.Buffer = true;
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = type;
Response.BinaryWrite(b);
Response.Flush();
Response.End();
Session["ContentLength"] = null;
Session["ContentType"] = null;
Session["ContentStream"] = null;
return Content("");
}
</code></pre>
<p>now all this i thought made sense but when i try it in my website the method never reaches the server (I placed a break-point at the beginning of both methods in the controller). I also used firefox's firebug to trace the script on the page until it reaches the line:</p>
<pre><code>$(myform).ajaxSubmit({ success:
function (responseText) {
var d = new Date();
$(imageId)[0].src = "/ImagePreview/ImageLoad?a=" + d.getMilliseconds();
if (document.all || is_chrome)//IE
imageLoadParent.appendChild(myform.firstChild);
else//FF
document.body.removeChild(myform);
}
});
</code></pre>
<p>here it continues but never enters the success condition. I thought it might be a problem with the JQuery versions included on the page and noticed that my friends site included: jquery-1.5.1.min.js, jquery-1.3.2.js and jquery_form.js</p>
<p>I added these to my website (which was using jquery-1.7.2.min.js) but the problem continued. Not sure if including various versions of jquery would cause some kind of conflict with the methods or if the problem is somewhere else.</p>
<p>I would greatly appreciate any help on the matter.
Thanks in advance.</p>

How to use swiftUI matched geometry to present a detail card view on top of elements (instead of increasing frame height)
|
<p>I am attempting my first steps using matchedgeometry and have followed some tutorials to get a simple view to expand when selected.I have two files, a card view and a content view. I would like to place all of my card views in a horizontal scrollview.</p>
<pre><code>import SwiftUI
struct smallCard: View {
@State private var flag: Bool = true
@Namespace var nspace
var body: some View {
if flag {
VStack{
Image("chemex.jpg")
.resizable()
.matchedGeometryEffect(id: "image", in: nspace)
.scaledToFill()
Spacer()
Button("CHEMEX") { withAnimation(.default) { flag.toggle() } }
.matchedGeometryEffect(id: "text", in: nspace)
Spacer()
.frame(height:8)
}
.matchedGeometryEffect(id: "geoeffect1", in: nspace)
.frame(width: 100, height: 100, alignment: .center)
.background(Color.white)
.cornerRadius(20)
.shadow(color: .gray, radius: 9, x: 0, y: 9)
}
if !flag {
VStack{
Image("chemex.jpg")
.resizable()
.matchedGeometryEffect(id: "image", in: nspace)
.scaledToFit()
Spacer()
Button("CHEMEX") { withAnimation(.default) { flag.toggle() } }
.matchedGeometryEffect(id: "text", in: nspace)
Spacer()
.frame(height:20)
}
.matchedGeometryEffect(id: "geoeffect1", in: nspace)
.layoutPriority(1)
.frame(width: 300, height: 600, alignment: .center)
.background(Color.white)
.cornerRadius(20)
.shadow(color: .gray, radius: 9, x: 0, y: 9)
}
}
</code></pre>
<p>I the have my main content view:</p>
<pre><code>import SwiftUI
struct ContentView: View {
var body: some View {
VStack{
HStack{
Text("My App")
.font(.title)
.padding(.leading, 25)
Spacer()
}
ScrollView(.horizontal){
HStack{
smallCard()
.padding(.horizontal)
smallCard()
.padding(.horizontal)
smallCard()
.padding(.horizontal)
}
}
}
.frame(alignment: .center)
}
</code></pre>
<p>This currently works for clicking on the small card and the matched geometry animates this to the larger card. The issue I have is that this changes the height of my scrollview and as such this moves everything else such as my title up and out of view.</p>
<p>Effectively what I would like to achieve is like a popover view, so that this detail view is on top of all of the elements in my content view, but whilst using matchedgeometry (or an alternative solution) to animate nicely between the views.</p>
<p>Is this possible? I am at the point where I do not know if there is a solution to this.</p>

Determine if dynamic selects are defined with javascript
|
<p>I've stumbled across a problem and could use your help figuring out some logic here to deal with it. Basically I have a dynamic order form where the price is updated real time on the user side using javascript based on what options the user selects. The issue is that there are 3 dynamic dropdowns that might not all exist, ie sometimes there will be drop down a - c, sometimes there will only be a, or just a and b, etc. The error I'm getting is that the variable for any undefined select is undefined (obviously). I've implemented some js to deal with that but with no success. Here is the code I'm working with:</p>
<p>PHP: </p>
<pre><code> $a_sql = ("SELECT * FROM prod_add WHERE pid = '$id' AND `group` = 'a'");
$a_query = mysqli_query($dbconx, $a_sql);
$a_Count = mysqli_num_rows($a_query);
if ($a_Count > 0) {
while($row = mysqli_fetch_array($a_query)) {
$a_option = $row["option"];
$a_value = $row["value"];
$a_results .= "<option value='$a_value'>$a_option</option>";
}
}
if($a_Count > 0) {
$a_opt = "<select class='opt_drop' id='optA' name='optA' onchange='getTotal()'>$a_results</select>";
} else {
$a_opt = "";
}
</code></pre>
<p>Rinse and repeat for b & c</p>
<p>HTML: </p>
<pre><code> <h2 id="totalPrice">$<?php echo $base_cost ?></h2> <br />
<input type="hidden" name="base_cost" id="base_cost" value="<?php echo $base_cost ?>" />
<?php echo $a_opt; ?><br />
<?php echo $b_opt; ?><br />
<?php echo $c_opt; ?>
Quantity:
<select name="quantity" id="quantity" onchange="getTotal()">
<option value="1"> 1 </option>
<option value="2"> 2 </option>
<option value="3"> 3 </option>
<option value="4"> 4</option>
<option value="5"> 5 </option>
<option value="6"> 6 </option>
<option value="7"> 7 </option>
<option value="8"> 8 </option>
<option value="9"> 9 </option>
<option value="10"> 10 </option>
</select>
</code></pre>
<p>Javascript:</p>
<pre><code> <script type="text/javascript">
function getDDValue(elementID){
var value = 0;
var element = document.getElementById(elementID);
value = element.options[element.selectedIndex].value;
console.log(value);
return parseFloat(value);
}
function getBase (elementID) {
var value = 0;
var element = document.getElementById(elementID);
value = element.value;
return parseFloat(value);
}
function getTotal(){
if (typeof optA != "undefined") {
var optA = getDDValue("optA");
} else {
var optA = "0";
}
if (typeof optB != "undefined") {
var optB = getDDValue("optB");
} else {
var optB = "0";
}
if (typeof optC != "undefined") {
var optC = getDDValue("optC");
} else {
var optC = "0";
}
var quantity = getDDValue("quantity");
var base_cost = getBase ("base_cost")
var totalPrice = '0';
totalPrice = parseFloat((+base_cost + +optA + +optB + +optC) * +quantity);
console.log(totalPrice);
document.getElementById('totalPrice').innerHTML = "$" + totalPrice;
}
getTotal();
</script>
</code></pre>
<p>As you can see above I tried determining if the value was undefined and if it was to just give it a value of 0. That didn't work though I can't be sure why. </p>

|
<p>My app is a weight loss app. It uses Devise for user authentication. </p>
<p>A user <code>has_one :profile</code> (the profile table holds the <code>user_id</code> as foreign key) that stores data like prename, surname etc. and is created automatically when a user signs up. A profile <code>has_many :weights</code> (users of the app should weigh themselves regularly and store their new weight in this table). So far so good. </p>
<p>I have the following problem:
If a logged in user goes to the index page of the weight controller he sees only his own weights. However, if this user now changes the profile_id in the URL bar he can also see the weights of that other profile (although it is not "his" profile). Additionally, he can now create a new weight, which then holds the other profile_id (which is obviously not his own).</p>
<p>What I managed to do is to generally restrict users to edit or destroy weights which do not hold their own profile_id (through <code>before_action :require_same_weight_profile</code> in my weights_controller.rb).</p>
<p>My question now: how can I prevent this user (that has a certain profile) to do the stuff described above?</p>
<p>I'm sure the answer is pretty simple (I started coding just a few months ago).</p>
<blockquote>
<p><strong>UPDATE</strong> In the meanwhile I found a solution. Unfortunately the suggested solutions in the comments did not work for me. What does
work is the following:</p>
<p><strong>My update in weights_controller.rb</strong></p>
<pre><code>before_action :require_permission
...
def require_permission
if current_user != Profile.find(params[:profile_id]).user
redirect_to root_path
end
end

"active" class somehow being removed from ".caret"
|
<p>Even though in my mouseover function, it explicitly says to add the class <code>active</code> to <code>.caret</code> <em>(make it grey)</em> when "Dropdown" is hovered over and the dropdown menu hidden, when you click on "Dropdown" twice (once to show menu; once to hide) and still have your cursor over "Dropdown", the caret fails to change color (turn grey), which is odd.</p>
<p>The only way to rectify this is by leaving the <code><span></code> element and then re-entering it, at which point, it turns grey as it should. However, I would like it to turn grey under every circumstance, as long as the span element is being hovered over and the dropdown is hidden.</p>
<p>The problem nevertheless seems to be that the <code>active</code> class is being removed somewhere, whenever "Dropdown" is clicked on twice, but I don't know where.</p>
<p>Anyone know how to fix this?</p>

How did I make recursive copies of my repo inside of itself?
|
<p>I forgot what I typed exactly last night, but I remember typing a git command incorrectly and wondering if I messed something up. I figured everything was fine, made a commit then went to sleep. </p>
<p>Now today, when I <code>git status</code> I get 100+ lines of </p>
<pre><code>new file: MyProject/MyProject/
new file: MyProject/MyProject/MyProject/
new file: MyProject/MyProject/MyProject/MyProject/
</code></pre>
<p>and so on. Every directory has a copy of all my code and resources, too.
<code>git checkout -- .</code> did not fix this. I can rebase to a previous commit since I remember all the changes from my last commit, but I'd like to know how I caused such a mess. </p>
<p>What the hell did I do and how can I fix this and never do it again?</p>

<pre><code><?xml version='1.0' encoding='utf-8'?>
<MyRootNode clientCode="German" recordCount="1">
<referrals>
<Individual>
<indvId>50853</indvId>
<firstName>Dad</firstName>
<middleName/>
<lastName>Test</lastName>
<suffixName/>
<gender>M</gender>
<race>WH</race>
<ethnicity>UN</ethnicity>
<DOB>2000-02-02</DOB>
<caseNumber>710645</caseNumber>
</Individual>
</referrals>
</MyRootNode>
</code></pre>
<p>As of now my beanio mapping file looks like :</p>
<pre><code><stream name="MyRootNode" format="xml">
<record name="referrals" class="example.test.TestBean">
<bean name="individual" class="example.test.Individual" xmlName="Individual">
<field name="indvId" />
<field name="firstName" minOccurs="1" />
<field name="middleName" minOccurs="1" />
<field name="lastName" minOccurs="1" />
<field name="suffixName" minOccurs="1" />
<field name="gender" minOccurs="1" />
<field name="race" minOccurs="1" />
<field name="ethnicity" minOccurs="1" />
<field name="DOB" minOccurs="1" />
<field name="caseNumber" minOccurs="1" />
</bean>
</record>
</stream>
</code></pre>
<p>Need to add <B><code>clientCode="German" recordCount="1"</code></B> to the MyRootNode. </p>
<p>Appreciate your help!</p>
<p>Thanks & Regards,
Rajiv</p>

Need help sharing a Javascript variable locally between files

<p>I've been developing a speed test typing game for some time now, and I've been stuck on how to take the time you finish from one HTML page (the game itself) to an alternate one (the score page). I've been trying to use import{} export{}, but I'm not 100% sure how they function and so they haven't exactly worked. I'll attach both the game HTML and Javascript code and the score HTML and Javascript code.</p>

Flutter Integration test: I can't target some of my widgets - Getter not found
|
<p>I am learning about integration testing in flutter and I'm running into a problem.</p>
<p>My app contains a sign-in button widget and my test starts with pumping it.</p>
<p>However, I can't seem to target it.</p>
<p>Every attempt results in the following error:</p>
<pre><code>integration_test/doctor_integration_test.dart:21:24: Error: Getter not found: 'SignInPage'.
expect(find.byType(SignInPage), findsOneWidget);
^^^^^^^^^^
FAILURE: Build failed with an exception.
</code></pre>
<p>The SignInPage is called within:</p>
<pre><code>MaterialApp _buildMaterialApp(BuildContext context) {
return MaterialApp(
title: 'Skinopathy: Doctor',
theme: ThemeData(
primarySwatch: Colors.blue,
visualDensity: VisualDensity.adaptivePlatformDensity,
),
routes: {
'/': (context) {
return BlocListener<AppBloc, AppState>(
listener: (context, state) {
if (state is AppAuthenticated) {
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (_) => WelcomePage(),
),
);
} else if (state is AppUnauthenticated) {
Navigator.pushReplacementNamed(context, '/sign_in');
} else if (state is AppOutdated) {
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (_) => OutdatedVersionPage(),
),
);
}
},
child: Center(
child: SplashPage(),
),
);
},
'/sign_in': (context) {
return SignInPage();
},
</code></pre>
<p>My presumption is that the integration takes place before the SignInPage is loaded.</p>
<p>_buildMaterialApp is also a child of Widget _buildRootLevelWidgets(BuildContext context)</p>
<p>How do I properly target SignInPage for testing?</p>
<p>Is there anything else I'm doing wrong?</p>
<p>Please note: I did NOT build this app; I'm just here to test it.</p>
<p>Thanks in advance!</p>

Issues connecting to server with sslv3 disabled in legacy perl
|
<p>As the title says, I'm attempting to POST some JSON to a REST API using a pretty old version of perl, specifically 5.10.1. I'm working in a pretty old legacy codebase on RHEL 6. The handshake fails with error 500 because the server has sslv3 disabled. However I'm using versions of LWP and IO::Socket::SSL that I believe nominally support at least TLSv1, which the server supports so I'm unsure why the connection fails as it should just use an acceptable cipher. The server appears to be behind a cloudfront reverse proxy which may be relevant. I don't know enough about SSL to say for certain, but it appears that the issue is in the way the server I care about is set up and how the version of perl and libraries in use implement the cipher. Using an online <a href="https://www.ssllabs.com/ssltest/analyze.html?d=dev.superquoteapi.fis.rcuh.com&s=99.84.224.116&latest" rel="nofollow noreferrer">tool</a> I noticed that the handshake fails on several browsers that do not support SNI. The version of openssl available should support this, but neither of the perl SSL implementations appear to. Is there a way around this? </p>
<p><a href="https://stackoverflow.com/questions/49166769/using-perl-5-8-8-with-openssl-1-0-1-to-connect-with-tlsv1-2">this</a> question seems to be dealing with a similar issue, but they solve it by installing a newer version of perl, which I'm not sure I can do given that this would likely break large portions of the codebase.</p>
<p><a href="https://bugzilla.redhat.com/show_bug.cgi?id=1355802" rel="nofollow noreferrer">This</a> unresolved bug seems to accidentally document this behavior
my problem is identical to the one listed, but I can also connect to the openssl host. I'm not sure that it's the same problem but I am on the same version of redhat with the same software and the same inconsistent behavior so it seems valuable. If it helps my software versions are as follows</p>
<pre><code>openssl-1.0.1e-58.el6_10.i686
perl-Crypt-SSLeay-0.57-17.el6.x86_64
perl-IO-Socket-SSL-1.31-3.el6_8.2.noarch
perl-Net-SSLeay-1.35-10.el6_8.1.x86_64
</code></pre>
<p>If I run </p>
<p><code>printf 'HTTP/1.0 200 Ok\r\n\r\n' | openssl s_server -accept 2000 -cert certificate.pem -key key.pem -no_ssl2 -no_ssl3 -no_tls1</code></p>
<p>the following script (test.pl) is able to connect using the same libraries </p>
<pre><code>my $ua = LWP::UserAgent->new(timeout => 600);
my $req = HTTP::Request->new(POST => $ARGV[0]);
$req->content_type('application/json');
$req->content_encoding('gzip');
$req->content('');
my $res = $ua->request($req);
print $res->status_line, "\n";
</code></pre>
<pre><code>>perl5.10.1 test.pl https://localhost:2000/
200 Ok
</code></pre>
<p>However, when I run an only slightly more complicated program using the same libraries and perl version I get errors relating to the sslv3 handshake</p>
<pre><code>500 Can't connect to dev.superquoteapi.fis.rcuh.com:443 (SSL connect attempt failed with unknown errorerror:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure)
</code></pre>
<p>I've even tried to force the program to use only TLSv1, but to no avail, the following line seems to have no impact</p>
<pre><code>my $ua = LWP::UserAgent->new(ssl_opts => {verify_hostname => 0}, SSL_version => '!TLSv12:TLSv1:!SSLv2:!SSLv3', allowed_protocols => ['https']);
</code></pre>
<p>The program I am actually working with is listed below</p>
<pre><code>use LWP;
use IO::Socket::SSL;
my $ua = LWP::UserAgent->new(ssl_opts => {verify_hostname => 0}, SSL_version => '!TLSv12:TLSv1:!SSLv2:!SSLv3', allowed_protocols => ['https']);
my $req = HTTP::Request->new('POST', 'https://dev.superquoteapi.fis.rcuh.com:443/api/quote');
$req->header('Content-Type' => 'application/json');
$req->header('Accept' => 'application/json');
#an api key is required and set in a header, but I won't list that here
open(my $fd, '<', 'data,json')
or die "Unable to open file, $!";
my @json=<$fd>;
close($fd)
or warn "Unable to close the file handle: $!";
$req->content(@json);
my $resp = $ua->request($req);
print $resp->as_string;
</code></pre>
<p>I have tried removing <code>IO::Socket::SSL</code> and replacing it with <code>Net::SSL</code> as is referenced in this question <a href="https://stackoverflow.com/questions/8026524/how-do-i-force-lwp-to-use-cryptssleay-for-https-requests">How do I force LWP to use Crypt::SSLeay for HTTPS requests?</a> but this does not seem to help. The code I used was </p>
<pre><code>use Net::SSL ();
BEGIN {
$Net::HTTPS::SSL_SOCKET_CLASS = "Net::SSL"; # Force use of Net::SSL
}
</code></pre>
<p>The two programs are more or less identical. The issue seems to be in the way the specific server <code>https://dev.superquoteapi.fis.rcuh.com</code> handles ssl requests. However I do not know enough about SSL/TLS to verify this meaningfully, so I have included both for completeness.</p>
<p>I apologize if this question is a bit rambling, but I really need help, and I just want to provide as much information as I can. If I can provide further information, or remove unhelpful information please let me know, I am absolutely at my wits end.</p>

Angular2: Unit-test router with cached template
|
<p>I'm dealing with some problems doing test on different environments:</p>
<ul>
<li><strong>SRC</strong>: unminified components, using both .js and .html/.css template files</li>
<li><strong>DIST</strong>: minified components (only .js, no templates)</li>
</ul>
<p>I made two different karma-conf and karma-test-shim, one for SRC and one for DIST.

How to disable d3plus timeline time formating?
|
<p>I have created a bar chart using d3plus. In the code I have created timeline using the following lines: <br></p>
<pre><code> .time({
"value": "__TIME__"
)
.timeline({
"align":"center",
"value":true})
</code></pre>
<p><br>
This is showing a timeline in my chart like below:<a href="https://i.stack.imgur.com/FQkDb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FQkDb.png" alt="enter image description here"></a></p>
<p>In my data, the <strong>__TIME__</strong> variable contains only numbers(1,2,3,4..). But the timeline converted it into months. I just want plain numbers (1,2,3,4....) instead of auto formatting of the time.
<br>
Is it possible to disable the auto formatting for the timeline?<br>
Here is the sample jsfiddle: </p>

Does Android TextView support state_pressed state?
|
<p>The real quest is to have a custom ButtonBar(as below) in Android with TextViews acts as buttons and each should reflect their state, pressed/selected.</p>
<p><a href="https://i.stack.imgur.com/nC620.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nC620.png" alt="enter image description here" /></a></p>
<p>The TextView is set with the following background for different states to reflect. What all states supported by Android TextView? Say e.g., if it supports states like pressed/selected, how to update the TextView from XML/Code?</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#ffffff">
<shape android:shape="rectangle">

Send a custom email with additional account fields values on save in Woocommerce 3
|
<p>On the basis of the plugin “Advanced Custom Fields” additional fields were created for the personal account of WooCommerce users. Using the second "ACF for WooCommerce" plugin, I placed these fields on the edit-account page.</p>
<p>If the user has filled in the fields or edited them, the administrator will receive an email with the values of these fields. The following code is responsible for notifications:</p>
<pre><code>if (!class_exists('WooCommerceNotifyChanges')) {
class WooCommerceNotifyChanges {
function __construct() {
add_action('woocommerce_save_account_details', array($this, 'woocommerce_send_notification'), 15, 1);
}
function woocommerce_send_notification($user_id) {
$body = '';
$to = 'info@domain.com';
$subject = 'Edit profile data';
update_meta_cache('user', $user_id); // delete cache
$user = new WP_User($user_id);
$user_name = $user->user_login;
$body .= '<table>';
$body .= '<tr><td>'.__("Profile"). '</td></tr>';
$body .= '<tr><td>Login: </td><td>'.$user_name. '</td></tr>';

<h3>Here two errors occur:</h3>
<ol>
<li><p>When a user edits these fields, old, apparently cached data is sent to the administrator email. When you re-send without editing, you will receive the correct field data.<br>
<br>
I put a line of code:</p>
<pre><code>update_meta_cache('user', $user_id);
</code></pre>
<p>But it does not work, the old data is still coming. Apparently, I did something wrong.</p></li>
<li><p>The data of all fields are correctly stored in the database and also correctly displayed in an email to the administrator. The problem with checkboxes.<br>
<br>
In this case, the "What style do you prefer?" three checkboxes "Classic", "Casual" and "Sport" are displayed. The user selected the "Casual" checkbox. The value of this field is correctly stored in the database.<br>
<br>
But in the email to the administrator, instead of this value, only the word “Array” comes.</p></li>
</ol>
<p>Tell me how to fix it?</p>
<p>Any help is appreciated.</p>

Perl, XML::Twig, how to reading field with the same tag
|
<p>I'm working on processing a XML file I receive from a partner. I do not have any influence on changing the makeup of this xml file. An extract of the XML is:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<objects>
<object>
<id>VW-XJC9</id>
<name>Name</name>
<type>House</type>
<description>
<![CDATA[<p>some descrioption of the house</p>]]> </description>
<localcosts>
<localcost>
<type>mandatory</type>
<name>What kind of cost</name>
<description>
<![CDATA[Some text again, different than the first tag]]>
</description>
</localcost>
</localcosts>
</object>
</objects>
</code></pre>
<p>The reason I use Twig is that this XML is about 11GB big, about 100000 different objects) . The problem is when I reach the localcosts part, the 3 fields (type, name and description) are skipped, probably because these names are already used before.</p>
<p>The code I use to go through the xml file is as follows:</p>
<pre><code>my $twig= new XML::Twig( twig_handlers => {
id => \&get_ID,
name => \&get_Name,
type => \&get_Type,
description => \&get_Description,
localcosts => \&get_Localcosts
});
$lokaal="c:\\temp\\data3.xml";
getstore($xml, $lokaal);
$twig->parsefile("$lokaal");
sub get_ID { my( $twig, $data)= @_; $field[0]=$data->text; $twig->purge; }
sub get_Name { my( $twig, $data)= @_; $field[1]=$data->text; $twig->purge; }
sub get_Type { my( $twig, $data)= @_; $field[3]=$data->text; $twig->purge; }
sub get_Description { my( $twig, $data)= @_; $field[8]=$data->text; $twig->purge; }
sub get_Localcosts{
my ($t, $item) = @_;
my @localcosts = $item->children;
for my $localcost ( @localcosts ) {
print "$field[0]: $localcost->text\n";
my @costs = $localcost->children;
for my $cost (@costs) {
$Type =$cost->text if $cost->name eq q{type};
$Name =$cost->text if $cost->name eq q{name};
$Description=$cost->text if $cost->name eq q{description};
print "Fields: $Type, $Name, $Description\n";
}
}
$t->purge;
}
</code></pre>
<p>when I run this code, the main fields are read without issues, but when the code arrives at the 'localcosts' part, the second for-next loop is not executed. When I change the field names in the xml to unique ones, this code works perfectly.</p>
<p>Can someone help me out?</p>
<p>Thanks</p>

Random <divs> onclick
|
<p>I'm trying to make a simple game where</p>
<ul>
<li><p>you start with 9 circles</p></li>
<li><p>when you click on a circle with a thicker border it's going to increment a score and cause new circles to be drawn randomly.</p></li>
</ul>
<p>I've already worked on counting stuff but I have a problem, because wherever you click (I mean whatever div) it sums up points. I don't have an idea about how to deactivate div's which do not have a thicker border. </p>
<p>Please tell if this is a good programming approach.</p>

batch file change bracket speciff my.ini

<pre><code># MySQL Server Instance Configuration File
# ----------------------------------------------------------------------
# Generated by the MySQL Server Instance Configuration Wizard
#
#
# Installation Instructions
# ----------------------------------------------------------------------
#
# On Linux you can copy this file to /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options
# (@localstatedir@ for this installation) or to
# ~/.my.cnf to set user-specific options.
#
# On Windows you should keep this file in the installation directory
# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
# make sure the server reads the config file use the startup option
# "--defaults-file".
#
# To run run the server from the command line, execute this in a
# command line shell, e.g.
# mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# To install the server as a Windows service manually, execute this in a
# command line shell, e.g.
# mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# And then execute this in a command line shell to start the server, e.g.
# net start MySQLXY
#
#
# Guildlines for editing this file
# ----------------------------------------------------------------------
#
# In this file, you can use all long options that the program supports.
# If you want to know the options a program supports, start the program
# with the "--help" option.
#
# More detailed information about the individual options can also be
# found in the manual.
#
#
# CLIENT SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
#
[client]
port=3306
[mysql]
default-character-set=latin1
# SERVER SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this
# file.
#
[mysqld]
# The TCP/IP Port the MySQL Server will listen on
port=3306
#Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files (x86)/MySQL/MySQL Server 5.1/"
#Path to the database root
datadir="C:/ProgramData/MySQL/MySQL Server 5.1/Data/"
# The default character set that will be used when a new schema or table is
# created and no character set is defined
character-set-server=latin1
# The default storage engine that will be used when create new tables when
default-storage-engine=INNODB
# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
# The maximum amount of concurrent sessions the MySQL server will
# allow. One of these connections will be reserved for a user with
# SUPER privileges to allow the administrator to login even if the
# connection limit has been reached.
max_connections=160
# Query cache is used to cache SELECT results and later return them
# without actual executing the same query once again. Having the query
# cache enabled may result in significant speed improvements, if your
# have a lot of identical queries and rarely changing tables. See the
# "Qcache_lowmem_prunes" status variable to check if the current value
# is high enough for your load.
# Note: In case your tables change very often or if your queries are
# textually different every time, the query cache may result in a
# slowdown instead of a performance improvement.
query_cache_size=99M
# The number of open tables for all threads. Increasing this value
# increases the number of file descriptors that mysqld requires.
# Therefore you have to make sure to set the amount of open files
# allowed to at least 4096 in the variable "open-files-limit" in
# section [mysqld_safe]
table_cache=320
# Maximum size for internal (in-memory) temporary tables. If a table
# grows larger than this value, it is automatically converted to disk
# based table This limitation is for a single table. There can be many
# of them.
tmp_table_size=103M
# How many threads we should keep in a cache for reuse. When a client
# disconnects, the client's threads are put in the cache if there aren't
# more than thread_cache_size threads from before. This greatly reduces
# the amount of thread creations needed if you have a lot of new
# connections. (Normally this doesn't give a notable performance
# improvement if you have a good thread implementation.)
thread_cache_size=8
#*** MyISAM Specific options
# The maximum size of the temporary file MySQL is allowed to use while
# recreating the index (during REPAIR, ALTER TABLE or LOAD DATA INFILE.
# If the file-size would be bigger than this, the index will be created
# through the key cache (which is slower).
myisam_max_sort_file_size=100G
# If the temporary file used for fast index creation would be bigger
# than using the key cache by the amount specified here, then prefer the
# key cache method. This is mainly used to force long character keys in
# large tables to use the slower key cache method to create the index.
myisam_sort_buffer_size=167M
# Size of the Key Buffer, used to cache index blocks for MyISAM tables.
# Do not set it larger than 30% of your available memory, as some memory
# is also required by the OS to cache rows. Even if you're not using
# MyISAM tables, you should still set it to 8-64M as it will also be
# used for internal temporary disk tables.
key_buffer_size=16M
# Size of the buffer used for doing full table scans of MyISAM tables.
# Allocated per thread, if a full scan is needed.
read_buffer_size=64K
read_rnd_buffer_size=256K
# This buffer is allocated when MySQL needs to rebuild the index in
# REPAIR, OPTIMZE, ALTER table statements as well as in LOAD DATA INFILE
# into an empty table. It is allocated per thread so be careful with
# large settings.
sort_buffer_size=256K
#*** INNODB Specific options ***
# Use this option if you have a MySQL server with InnoDB support enabled
# but you do not plan to use it. This will save memory and disk space
# and speed up some things.
#skip-innodb
# Additional memory pool that is used by InnoDB to store metadata
# information. If InnoDB requires more memory for this purpose it will
# start to allocate it from the OS. As this is fast enough on most
# recent operating systems, you normally do not need to change this
# value. SHOW INNODB STATUS will display the current amount used.
innodb_additional_mem_pool_size=12M
# If set to 1, InnoDB will flush (fsync) the transaction logs to the
# disk at each commit, which offers full ACID behavior. If you are
# willing to compromise this safety, and you are running small
# transactions, you may set this to 0 or 2 to reduce disk I/O to the
# logs. Value 0 means that the log is only written to the log file and
# the log file flushed to disk approximately once per second. Value 2
# means the log is written to the log file at each commit, but the log
# file is only flushed to disk approximately once per second.
innodb_flush_log_at_trx_commit=1
# The size of the buffer InnoDB uses for buffering log data. As soon as
# it is full, InnoDB will have to flush it to disk. As it is flushed
# once per second anyway, it does not make sense to have it very large
# (even with long transactions).
innodb_log_buffer_size=6M
# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and
# row data. The bigger you set this the less disk I/O is needed to
# access data in tables. On a dedicated database server you may set this
# parameter up to 80% of the machine physical memory size. Do not set it
# too large, though, because competition of the physical memory may
# cause paging in the operating system. Note that on 32bit systems you
# might be limited to 2-3.5G of user level memory per process, so do not
# set it too high.
innodb_buffer_pool_size=570M
# Size of each log file in a log group. You should set the combined size
# of log files to about 25%-100% of your buffer pool size to avoid
# unneeded buffer pool flush activity on log file overwrite. However,
# note that a larger logfile size will increase the time needed for the
# recovery process.
innodb_log_file_size=114M
# Number of threads allowed inside the InnoDB kernel. The optimal value
# depends highly on the application, hardware as well as the OS
# scheduler properties. A too high value may lead to thread thrashing.
innodb_thread_concurrency=10

<p>In my FCFS function I call other functions to perform the calculations</p>
<pre><code>void FCFS(List<Process> p)
{
output.Items.Add("After FCFS");
output.Items.Add("-------------------------------------------------------");
wait(p);
turnaroundtime(p);
responsetime(p);
completeoutputlist(p);
}
</code></pre>
<p>my attempts at wait time have failed and I really don't know how to best approach this. I want to get these values calculated here so then I can call them in my other functions.
I'm mostly stuck on how to take I/o time into account when calculating the clock</p>
<p>the processes are doing I/O at the same time one other process is running. So, I/O should be decremented as timer is incremented for every process doing I/O.
multiple processes can be doing i/o at the same time. So you would need a list of processes that are doing i/o.
really just need some guidance in this part.</p>
<pre><code>void wait(List<Process> p)
{
/* Goal keep track of context switches. - p.contextswitch
* Keep track of the first time it enters to get response time - p.start
* Keep track of when the process ends - so later we can calc turnaround time p.end
* then tweak some functions so it works again
*
*/
}

<p>Before I was doing something like this</p>
<pre><code>void wait(List<Process> p)
{
/* Goal keep track of context switches. - p.contextswitch
* Keep track of the first time it enters to get response time - p.start
* Keep track of when the process ends - so later we can calc turnaround time p.end

Database insertion is taking zero seconds to insert
|
<p>I am trying to measure the performance of <code>Database Insert</code>. So for that I have written a <code>StopWatch</code> class which will reset the counter before <code>executeUpdate</code> method and calculate the time after <code>executeUpdate</code> method is done.</p>
<p>And I am trying to see how much time each thread is taking, so I am keeping those numbers in a <code>ConcurrentHashMap</code>. </p>
<p>Below is my main class-</p>
<pre><code>public static void main(String[] args) {
final int noOfThreads = 4;
final int noOfTasks = 100;
final AtomicInteger id = new AtomicInteger(1);
ExecutorService service = Executors.newFixedThreadPool(noOfThreads);
for (int i = 0; i < noOfTasks * noOfThreads; i++) {
service.submit(new Task(id));
}
while (!service.isTerminated()) {
}
//printing the histogram
System.out.println(Task.histogram);
}
</code></pre>
<p>Below is the class that implements Runnable in which I am trying to measure each thread performance in inserting to database meaning how much time each thread is taking to insert to database-</p>
<pre><code>class Task implements Runnable {
private final AtomicInteger id;
private StopWatch totalExecTimer = new StopWatch(Task.class.getSimpleName() + ".totalExec");
public static ConcurrentHashMap<Long, AtomicLong> histogram = new ConcurrentHashMap<Long, AtomicLong>();
public Task(AtomicInteger id) {
this.id = id;
}
@Override
public void run() {
dbConnection = getDBConnection();
preparedStatement = dbConnection.prepareStatement(Constants.INSERT_ORACLE_SQL);
//other preparedStatement
totalExecTimer.resetLap();
preparedStatement.executeUpdate();
totalExecTimer.accumulateLap();
final AtomicLong before = histogram.putIfAbsent(totalExecTimer.getCumulativeTime() / 1000, new AtomicLong(1L));
if (before != null) {
before.incrementAndGet();
}
}
}
</code></pre>
<p>Below is the <code>StopWatch class</code></p>
<pre><code>/**
* A simple stop watch.
*/
protected static class StopWatch {
private final String name;
private long lapStart;
private long cumulativeTime;
public StopWatch(String _name) {
name = _name;
}
/**
* Resets lap start time.
*/
public void resetLap() {
lapStart = System.currentTimeMillis();
}
/**
* Accumulates the lap time and return the current lap time.
*
* @return the current lap time.
*/
public long accumulateLap() {
long lapTime = System.currentTimeMillis() - lapStart;
cumulativeTime += lapTime;
return lapTime;
}
/**
* Gets the current cumulative lap time.
*
* @return
*/
public long getCumulativeTime() {
return cumulativeTime;
}
public String getName() {
return name;
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append(name);
sb.append("=");
sb.append((cumulativeTime / 1000));
sb.append("s");
return sb.toString();
}
}
</code></pre>
<p>After running the above program, I can see 400 rows got inserted. And when it is printing the histogram, I am only seeing like this-</p>
<pre><code>{0=400}
</code></pre>
<p>which means 400 calls came back in 0 seconds? It's not possible for sure.</p>
<p><strong>I am just trying to see how much time each thread is taking to insert the record and then store those numbers in a <code>Map</code> and print that map from the main thread.</strong> </p>
<p>I think the problem I am assuming it's happening because of thread safety here and that is the reason whenever it is doing <code>resetlap</code> zero is getting set to Map I guess.</p>
<p>If yes how can I avoid this problem? And also it is required to pass <code>histogram map</code> from the main thread to constructor of Task? As I need to print that Map after all the threads are finished to see what numbers are there.</p>
<p><strong>Update:-</strong>
If I remove <code>divide by 1000</code> thing to store the number as milliseconds then I am able to see some numbers apart from <code>zero</code>. So that looks good. </p>
<p>But One thing more I found out is that numbers are not consistent, If I sum up each threads time, I will get some number for that. And I also I am printing how much time in which whole program is finishing as well. SO I compare these two numbers they are different by big margin</p>

MongoDB aggregation graphlookup child's parent
|
<p>I've got some documents representing folders. I'd like to match every folder's parent if it has one.</p>
<pre><code>{"_id":{"$oid":"5f8c406fc8c88110e0d927f2"},"name":"A"}
{"_id":{"$oid":"5f8c406fc8c88110e0d927f3"},"parentFolderId":"5f8c406fc8c88110e0d927f2","name":"B"}
</code></pre>
<p>Even if the parent-child relationships are deeper, for <strong>A</strong> I need an <strong>empty parent folder</strong>, and for <strong>B</strong> <strong>parent folder A</strong>. I tried to use GraphLookup for this but it's not working (every <code>parentFolder</code> is empty), and I don't know what I'm missing:</p>
<pre><code>db.folders.aggregate([
{
$addFields: {
convertedId: { $toString: "$_id" }
}
},
{
$graphLookup: {
from: "folders",
startWith: "$parentFolderId",
connectFromField: "parentFolderId",
connectToField: "convertedId",
as: "parentFolder",
maxDepth: 0,
}
}
])
</code></pre>
<p>If I flip the <code>startWith</code>, <code>connectFromField</code>, <code>connectToFields</code> respectively, I get the <em>reverse</em> of what I need, A has an array which is containing B, B has nothing.</p>
<p>Edit:</p>
<p>With the non-working lookup, I get the following result:</p>
<pre><code>{ "_id" : ObjectId("5f8c406fc8c88110e0d927f2"), "name" : "A", "convertedId" : "5f8c406fc8c88110e0d927f2", "parentFolder" : [ ] }
{ "_id" : ObjectId("5f8c406fc8c88110e0d927f3"), "parentFolderId" : "5f8c406fc8c88110e0d927f2", "name" : "B", "convertedId" : "5f8c406fc8c88110e0d927f3", "parentFolder" : [ ] }
</code></pre>
<p>What I'd need is something like:</p>
<pre><code>{ "_id" : ObjectId("5f8c406fc8c88110e0d927f2"), "name" : "A", "convertedId" : "5f8c406fc8c88110e0d927f2", "parentFolder" : [ ] }
{ "_id" : ObjectId("5f8c406fc8c88110e0d927f3"), "parentFolderId" : "5f8c406fc8c88110e0d927f2", "name" : "B", "convertedId" : "5f8c406fc8c88110e0d927f3", "parentFolder" : [ { "_id" : ObjectId("5f8c406fc8c88110e0d927f2"), "name" : "A", "convertedId" : "5f8c406fc8c88110e0d927f2" } ] }
</code></pre>
<p>The only difference I see from the official "reportsTo" example that I'm using the ID field to match the documents, but that shouldn't be a problem, since I'm not using the ObjectID: <a href="https://docs.mongodb.com/manual/reference/operator/aggregation/graphLookup/" rel="nofollow noreferrer">https://docs.mongodb.com/manual/reference/operator/aggregation/graphLookup/</a></p>

android how to have a fixed layout but it will also adjust itself on different screensize

<p>I am developing some calculation app. This app will display the results on a table. For now i use "wrap_content" on height and width plus weight of my layout which will make it adjusting the border itself. However this make the table looks poorly designed . The example::</p>

<p>The class is called Attend. the ListViews show the values in the array when there is one value in the array. If there is more than one value the app crashes. I have checked that the array is being filled correctly and it is. Hopefully the error log has the answer. The error log I am getting is below:</p>

<p>again the error only appears when there is more than one value in the array. I have tried to find an answer to this problem but I couldnt find any info on the error. please help! thankyou!</p>
<p>UPDATE: this is how the array is filled and created:</p>
<pre><code>for(int i = 0; i < json_array_amparticipants.length(); i++){
//store all the amparticipants
str_amparticipant_email = new String[json_array_amparticipants.length()];
str_amparticipant_firstname = new String[json_array_amparticipants.length()];
str_amparticipant_lastname = new String[json_array_amparticipants.length()];
str_amparticipant_attendingam = new String[json_array_amparticipants.length()];
str_amparticipant_attendingpm = new String[json_array_amparticipants.length()];
//full_name_am = new String[json_array_amparticipants.length()];
str_amparticipant_email[i] = json_array_amparticipants.getJSONObject(i).getString("email");
str_amparticipant_firstname[i] = json_array_amparticipants.getJSONObject(i).getString("first_name");
str_amparticipant_lastname[i] = json_array_amparticipants.getJSONObject(i).getString("last_name");
str_amparticipant_attendingam[i] = json_array_amparticipants.getJSONObject(i).getString("attending_am");
str_amparticipant_attendingpm[i] = json_array_amparticipants.getJSONObject(i).getString("attending_pm");
//full_name_am[i] = str_amparticipant_firstname[i] + str_amparticipant_lastname[i];
}
</code></pre>
<p>FIXED: I am creating new arrays every time so it still stores the value but it causes the crash... heres the updated fix. Cheers guys:</p>
<pre><code> //store all the amparticipants
str_amparticipant_email = new String[json_array_amparticipants.length()];
str_amparticipant_firstname = new String[json_array_amparticipants.length()];
str_amparticipant_lastname = new String[json_array_amparticipants.length()];
str_amparticipant_attendingam = new String[json_array_amparticipants.length()];

How to loop data imported from SQLite database

<p>I am building an <strong>Express</strong> app ,and i am using <strong>SQLite</strong> database, I managed to fetch the data from the database, but I want to display it in the interface ,So i did this :</p>
<p><strong>index.js</strong></p>
<pre class="lang-js prettyprint-override"><code>/* GET THE LIST OF HOMES*/
router.get('/:homes-list', (req,res) => {

const home = rows.map(function(row) {
return {

}
});
res.locals.homes = home;
console.log(res.locals.homes)
res.redirect("/:homes-list", {home: res.locals.homes})
});
});

<p>Then I tried to display it for the user interface using <strong>EJS:</strong></p>

jQuery Toggle button not clickable after first click
|
<p>The menu expands and contracts when I click on a button.
The button toggles the "active" class when I click it as expected with only the code required for that action.
However, when I add the code to make the the menu contract when clicking elsewhere on the page, it only contracts when clicking everything EXCEPT for the button.
The button is no longer clickable and the menu remains expanded until I click on a link or on the body of the page.</p>
<p>EDIT: As I was typing this out on a jsfiddle, I got an error on that console that I don't see in my dev tools:
<strong>Uncaught ReferenceError: jQuery is not defined</strong>
The reason why I am not using the "$"symbol that I see everyone using, and I am writting out "jQuery" in front of everything is because that's the only way I could make DIVI (the wordpress builder) compile the code</p>
<pre><code>jQuery(document).ready(function(){
jQuery('.nav__button').click(function(){
jQuery(this).toggleClass('button--active');
jQuery('.nav__row').toggleClass('nav__row--active');
});
});
jQuery(document).mouseup(e => {
if (!jQuery('nav__container').is(e.target)
&& jQuery('nav__container').has(e.target).length === 0) {
jQuery('.nav__row').removeClass('nav__row--active');
jQuery('.nav__button').removeClass('button--active');
}
});
</code></pre>
<p>And If I add this line of code, I break the code all together.</p>
<pre><code>jQuery('.nav__button').is(e.target) ||
</code></pre>
<p>This line is added to the second function, to say that "If I click on the button OR elsewhere" [contract the menu]</p>

<p>I want to make my player's velocity follow the shape of a curve hence the acceleration applied is the difference between target speed scaled by movement direction and the velocity.
The issue with this is that, since the Integrator scales values by dt the <em>actual</em> acceleration is far lower than it needs to be.
I'm sure this is a simple fix but I really cannot quite figure out the math here.</p>

spatial domain convolution not equal to frequency domain multiplication using pytorch
|
<p>I want to verify if 2D convolution in spatial domain is really a multiplication in frequency domain, so I used pytorch to implement convolution of an image with a 3×3 kernel (both real). Then I transformed both the image and the kernel into frequency domain, multiplied them, transformed the result back to spatial domain. Here's the result:<br>
When the kernal is even or odd (i.e. pure real or pure imaginary in frequency domain), results of the two transforms seem to match well. I use min and max of both results to evaluate because I'm not sure if some margin alignment problems may affect direct difference. Here are three runs of either even and odd kernel:</p>
<pre><code># Even Kernel
min max with s-domain conv: -0.03659552335739136 4.378755569458008
min max with f-domain mul: -0.0365956649184227 4.378755569458008
min max with s-domain conv: -1.2673343420028687 2.397951126098633
min max with f-domain mul: -1.2673344612121582 2.397951126098633
min max with s-domain conv: -8.185677528381348 0.22980886697769165
min max with f-domain mul: -8.185677528381348 0.22980868816375732
# Odd Kernel
min max with s-domain conv: -1.6630988121032715 1.6592578887939453
min max with f-domain mul: -1.663098692893982 1.6592577695846558
min max with s-domain conv: -3.483165979385376 3.4751217365264893
min max with f-domain mul: -3.483165979385376 3.475121259689331
min max with s-domain conv: -1.7972984313964844 1.7931475639343262
min max with f-domain mul: -1.7972984313964844 1.7931475639343262
</code></pre>
<p>But if I use neither even or odd kernel, the difference is just at another level:</p>
<pre><code>min max with s-domain conv: -2.3028392791748047 1.675748348236084
min max with f-domain mul: -2.5289478302001953 1.4919483661651611

min max with f-domain mul: -1.6832940578460693 5.688591957092285

<p>I was wondering if this arises from precision in floating point. But I tried torch's complex128, it wasn't any better. Is there something wrong with my implementation? Or it is inevitable due to calculation with complex numbers?</p>
<p>Here's a simplified version of my code that could produce this result.</p>
<pre><code>import torch.nn.functional as F
import torch.fft as fft
import torch, cv2
img = cv2.imread('test.png', 0)
x = torch.as_tensor(img).unsqueeze(0)/255
k = torch.randn(1, 1, 3, 3)
for i in range(k.size(0)):
for j in range(k.size(1)):
# For even k
# for p in range(k.size(2)):
# for q in range(k.size(3)):
# k[i, j, p, q] = k[i, j, 2-p, 2-q]
# For odd k
# for p in range(k.size(2)):
# k[i, j, p, 0] = -k[i, j, p, 2]
# k[i, j, p, 1] = 0
# for q in range(k.size(3)):
# k[i, j, 0, q] = -k[i, j, 2, q]
# k[i, j, 1, q] = 0
pass
### Spatial domain convolution
padx = F.pad(x, [1,1,1,1])
sdc = F.conv2d(padx.unsqueeze(0), k)
### Frequency domain convolution
# Transform input
fdx = fft.rfft2(x)
sdfdx = fft.irfft2(fdx)
# Transform kernel
size_diff = x.size(-1)-k.size(-1)
padk = torch.roll(F.pad(k, [0,size_diff,0,size_diff]), (-1,-1), (-1, -2))
fdk = fft.rfft2(padk)
# Frequency domain multiplication
fdc = fdk * fdx
fdc = fdc.squeeze(0)
# Back to spatial domain
sdfdc = fft.irfft2(fdc)
### Compare
print("min max with s-domain conv:", sdc.min().item(), sdc.max().item())
print("min max with f-domain mul:", sdfdc.min().item(), sdfdc.max().item())
