<p><strong>2) I also have the following index array:</strong></p>
<p>[2010-10-19 06:32:00, 2010-10-19 06:35:00]</p>
<p><strong>3) I want to reindex the DataFrame according to the index array</strong> such that the new DataFrame will only have the 2 rows of the index array, while managing to resample it so that the high of the first row of the new dataframe is the higher of the highs from the first 2 rows of the original dataframe, the low of the second row of the new dataframe is the lower of the 3 lows in the original dataframe, etc.</p>
<p>Normally, one would aggregate one's data via .resample() and .agg(), but that's once you already have the dataframe in the state that you want. I can't use reindex() in such a way that I could follow it up with .resample() and accomplish this.</p>
<p>I suppose I'm looking for a way to reindex and resample in one move. How do I best do this?</p>

Vertical alignment for two inline-block elements not working as expected
|
<p>In the code below, why do I need to set <code>vertical-align: top</code> to both elements to close the gap between them? If the gap occurs on the first element only, can't I just set that to <code>vertical-align: top</code> to close the gap?</p>
<p>Here is what occurred if I assign vertical-align property to only <code>.test</code> :</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">

<p>I finished all, without update,delete and searching. Can you please looking my code and help me or give the advice, link or something useful.</p>
<p>this is my abstract model:</p>
<pre><code>public class ddispmodel extends AbstractTableModel {
private final String[] columnNames = { "FirstName", "SecondName", "Date of
birth", "Gender", "Email", "Address", "Number", "Attending","ID" };
private ArrayList<String[]> Data = new ArrayList<String[]>();
private boolean editable;
public void AddCSVData(ArrayList<String[]> DataIn) {
this.Data = DataIn;
this.fireTableDataChanged();
}
@Override
public int getColumnCount() {
return columnNames.length;// length;
}
@Override
public int getRowCount() {
return Data.size();
}
@Override
public String getColumnName(int col) {
return columnNames[col];
}
@Override
public Object getValueAt(int row, int col) {
return Data.get(row)[col];
}
public boolean isCellEditable(int row, int col) {
setValueAt(Data, row, col);
this.fireTableCellUpdated(row, col);
return true;
}
}
</code></pre>
<p>This is part of my main class
It is action Listener of menu item witch activate displaying function
(I didn't copy all class, because it nearly 1000 lines, but if it necessary, i can submit all code )</p>

public void actionPerformed(ActionEvent e){
CSVFileDomestic Rd = new CSVFileDomestic();
ddispmodel ddispm = new ddispmodel();
ddisp.setModel(ddispm);
File DataFile = new File("D:\\cdne4\\WorkPlace\\Domestic.csv");
ArrayList<String[]> Rs2 = Rd.ReadCSVfile(DataFile);
ddispm.AddCSVData(Rs2);
System.out.println("Rows: " + ddispm.getRowCount());

while (brd.ready()) {
String st = brd.readLine();
OneRow = st.split(",");
Rs.add(OneRow);

Table overflowing after adding more headers

<p>I am having issues with a table that is overflowing after adding a few headers.
For some reason, after I add more than one header, my table shifts to the right.</p>
<p>This is how the original table looks like:
<a href="https://i.stack.imgur.com/xxn02.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xxn02.jpg" alt="table" /></a>
You can see everything fits. However, after adding three more headers, the table shifted.</p>

Are there better alternatives to g.drawString() / g2D.drawString()? (solved)
|
<p>I have been trying to put text onto an already existing window for a while now.
I want to be able to add, remove, arrange and rearrange paragraphs across the screen.</p>
<p>At first I tried to add text components - which had a delay of several seconds.
Next I experimented with geometry in the paint component of JPanel-derivate, was delighted at how everything appeared instantly, and fell for a delusion that text would behave the same. But when I tried the drawString() method, I was met with a similar delay as before.
Maybe this is a problem with my computer specifically and doesn't happen elsewhere.
I would still like to remedy it though.</p>
<p>Eventually I wrote this monstrosity:</p>

<p>… which works fine, but has the problem that I will need to transcribe all the geometric information from any font that I would want to use - thus I am not quite sure if I should keep building on it or if that would just be a waste of time.</p>
<p>Update: Under a different Question I found the info that drawString() only needs a few seconds to load the font you are using when you draw your very first words. After that it apparently works (for practical purposes) instantly - I don't know why I never thought to check what would happen with the seconds line of text that I would ask the computer to draw.</p>

Making a Leaderboard in R Shiny
|
<p>I am attempting to make a leaderboard in R Shiny for my school where users could submit their name, teacher's name, and their score in textInputs by clicking an actionButton. I am having trouble with the following:</p>
<p>a) Making the textInputs submit on the push of the actionButton (I know I should use the isolate function, but have no idea where/when/how)</p>
<p>b) Storing the info the user inputs with the data frame so that when the app opens on a second device it still shows the info the first person uses</p>
<p>My code is below:</p>
<pre><code>### Libraries
library('tidyverse')
library('readxl')
library('shiny')
library('DT')
# Define UI
ui <- fluidPage(
# Application title
titlePanel("Scoreboard"),
# Sidebar
sidebarLayout(
sidebarPanel(
h5("Sidebar Text"),
),
# Main Panel
mainPanel(
tabsetPanel(type = "tabs",
tabPanel("Add Score",
textInput("name_input", "Insert Your Name Below"), textInput("teacher_input", "Insert Your Teacher's Last Name Below"),
textInput("score_input", "Insert Your Score Below"),
actionButton("sumbit_button", "Click Button to Submit!")
),
tabPanel("ScoreBoard", dataTableOutput("score_table"))
)
)
)
)
# Define server logic
server <- function(input, output) {
# Read In Sample Scores as a base dataframe to add user inputs to.
scores <- read_excel("Sample_Scores.xlsx")
scores <- scores[order(scores$Scores, decreasing = FALSE),]
names(scores) <- c("Score", "Name", "Teacher")
output$score_table <- renderDataTable({
new_score <- input$score_input
new_name <- input$name_input
new_teacher <- input$teacher_input
new_student <- c(new_score, new_name, new_teacher)
scores <- rbind(scores, new_student)
})
}
# Run the application
shinyApp(ui = ui, server = server)

Database row is not deleting, AJAX, PHP error
|
<p>I want to remove DB row data from HTML table. I have an HTML table where I have called all the database table values. I want to give a delete order option to the user. I have used a delete button for that. To do this, I am trying to use ajax and jquery with php delete query. But the issue is When I click on delete it just deletes the HTML row data. It should delete that particular id row from DB as well. I need your help. Please let me know what I have done wrong? I am very much new to ajax and jquery.</p>
<p>remove.php</p>
<pre><code><?php

R FlexDashboard ggiraph chart not showing on second page of dashboard when using IE 11
|
<p>I have a multi-page R FlexdashBoard and I am trying to use ggiraph to create some interactive charts. They show up fine on the first page of the dashboard, however on the second page the SVG graphics do not show up until I hit refresh then the charts on the first page disappear. Also the text in the SVG graphics seems to only display intermittently. I only have this error in Internet Explorer - everything works fine in Chrome. The following code should recreate this error.</p>

Highcharts Tootip in wrong location for multiple x axis

<p>I've got a chart with two x axis side-by-side, with one series in each. When I float over the Series 1 data, I see the tooltip, as expected. When I float over Series 2 data, it highlights the line, but no tooltip. However, if I move the cursor to the left at the same height as the data in Series 2 data, but above the Series 1 data, the tooltip shows the Series 2 information, and the Series 2 points are highlighted.

<ul>
<li>How can I solve this?</li>
<li>How can I remove the service from the service catalog?</li>
<li>Do I need to have a seperate deployment for the MI to make integrations in APIM or can APIM somehow run the Integrations itself. I am confused here because EI download page states that APIM includes the capabilities of EI. However, <a href="https://apim.docs.wso2.com/en/latest/get-started/integration-quick-start-guide/" rel="nofollow noreferrer">https://apim.docs.wso2.com/en/latest/get-started/integration-quick-start-guide/</a> it seems like MI should be seperately installed.</li>

@media (min-width: 840px) {...}
</code></pre>
<p>I expect each one to overwrite these who are before it [e.g. <code>@media (min-width: 840px) {...}</code> will overwrite <code>@media (min-width: 600px) {...}</code> and <code>@media (min-width: 400px) {...}</code>] based on the current viewport.</p>
<hr />
<p>I am using Sass to generate multiple <code>@media queries</code> as well as a bunch of <code>classes</code>, but its probably not to something being <em>wrong</em> in the code, but something being <em>missing</em>.</p>
<p>So what is this supposed to do?</p>
<p>The number of columns changes based on the viewport.</p>
<pre><code>$breakpoints: (
//name bp col-count
xs: [0 4],
sm: [400 4],
md: [600 8],
lg: [840 12],
xl: [1024 12],
xxl: [1440 12],
);
</code></pre>
<p>Imagining I am in the <code>xs</code> breakpoint, which reaches froom <code>0px</code> to <code>400px</code>, and I have a column with the class <code>xs:col:11</code>, then I don't want it with to be <code>100vw / (12 / 11)</code> [<code>91.6666667</code>], but <code>100%</code>. So naturally I am trying to overwrite each class, <strong>however</strong>:</p>
<p><a href="https://i.stack.imgur.com/L4NNP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/L4NNP.png" alt="enter image description here" /></a></p>
<p>It stops overwriting after the second <code>@media querie</code>, I expect it to still be 6 columns until the <code>sm</code> breakpoint.</p>
<hr />
<p>Below you can see my code and <a href="https://codepen.io/SimplyCius/pen/RwajMjy" rel="nofollow noreferrer">here</a> is a Codepen too.</p>

Visual Studio 2017 reports this error for my multi-platform xamarin App
|
<p>Someone Help I have been on this issue for 4 days, my app was working perfectly fine when it started reporting this error "This debug engine does not support exception conditions. The condition(s) will be ignored". It does not find some of the dll.so packages, I tried deleting the bin and debug folder, and rebuild the App, I have also reinstalled and installed visual studio, formatted my PC and did a clean installation all to no avail. The same comes up, when I try running the same app from different user in the project Repo in gitlab. I tried different emulators and now using my phone but still mp solution. </p>

My excel userform becomes unresponsive the next time I load it
|
<p>I have two forms, a login form to authenticate users to enter the system and a main form to work with if the authentication is successful. I work with an access database to search for the valid users and also to populate lists in the main form.</p>
<p><a href="https://i.stack.imgur.com/nvHhR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nvHhR.png" alt="The user form for authentication"></a></p>
<p>And here is the code for that:</p>
<pre><code>Private Sub CancelCommandButton_Click()
CloseDatabase
Unload Me
End Sub
Private Sub ConfirmCommandButton_Click()
...
End Sub
Private Sub UserForm_Initialize()
ConnectDatabase
End Sub
Private Sub OpenMainForm()
Unload Me
MainForm.Show
End Sub
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
If CloseMode = vbFormControlMenu Then
Cancel = True
End If
End Sub
</code></pre>
<p>And here is the code for managing main form load-up and close:</p>
<pre><code>Public Sub UpdateControls()
PopulateUserList
End Sub
Private Sub UserForm_Activate()
sTag = Split(Me.Tag, "|")
If sTag(0) <> "1" Then
Me.MainFormMultiPage.Pages(0).Enabled = False
Me.MainFormMultiPage.Value = 1
Else
Me.MainFormMultiPage.Pages(0).Enabled = True
Me.MainFormMultiPage.Value = 0
UpdateControls
End If
UserLabel1.Caption = sTag(1)
UserLabel2.Caption = sTag(1)
UserLabel3.Caption = sTag(1)
End Sub
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
If CloseMode = vbFormControlMenu Then
' Tip: If you want to prevent closing UserForm by Close (×) button in the right-top corner of the UserForm, just uncomment the following line:
' Cancel = True
Dim answer As Integer
answer = MsgBox("ÂíÇ ãØãÆäíÏ ˜å ãí ÎæÇåíÏ ÇÒ ÓÇãÇäå ÎÇÑÌ ÔæíÏ¿", vbYesNo + vbQuestion, "ÎÑæÌ ÇÒ ÓÇãÇäå")
If answer = vbYes Then
CloseDatabase
Else
Cancel = True
End If
End If
End Sub
Private Sub UserForm_Terminate()
loginForm.Show
End Sub
</code></pre>
<p>When I close the main form by clicking 'X' button, the login form reappears and the main form is closed; But when I login again (preferably using the same credentials) the main form is displayed but totally unresponsive (No list population, 'X' button doesn't work or any other controls in the form).</p>
<p>What should I do? Does the code in the UserForm_CloseQuery() unload the main form and all of its macros and I can't get the required events back to function or am I missing something?</p>
<p>It's not a time I started coding VBA and I can't make the head or tail of it easily when new problems arise. Any help would be appreciated. Thanks</p>

How to transfer an image to another component using Redux?
|
<p>I've set up my Redux to capture a user selection from a webshop (item, size, price) and send it to another <code>Cart</code> component. This is working perfectly, but I want to capture an image of the item and send it to <code>Cart</code>. Within each product page where you can add an item to the cart there is an image that I also would like to send with the user selection. This is an example of the product page component:</p>
<pre><code>import React, { Component } from 'react';
import { connect } from 'react-redux';
import { addCart } from '../../actions';
import SeltzShirt from './seltzshirt.jpg';
import Slideone from './slideSeltzOne';
import Slidetwo from './slideSeltzTwo';
import RightArrow from './rightarrow';
import LeftArrow from './leftarrow';
export class ProductPage3 extends Component {
constructor(props) {
super(props);
this.state = {
slideCount: 1,
value: 'medium', cartData: {}
}
this.nextSlide = this.nextSlide.bind(this);
this.previousSlide = this.previousSlide.bind(this);
this.handleClick = this.handleClick.bind(this);
this.change = this.change.bind(this);
}
handleClick() {
let cart = {price:25,item:this.description.innerHTML,size:this.state.value};
this.props.onCartAdd(cart);
console.log(cart);
this.itemSelection(cart);
}
...
componentDidMount () {
window.scrollTo(0, 0)
}
render() {
return (
<div className= "ProductPage" id="ProductPage">
<div id='slider'>
{this.state.slideCount === 1 ? <Slideone /> : null}
{this.state.slideCount === 2 ? <Slidetwo /> : null}
<RightArrow nextSlide={this.nextSlide} />
<LeftArrow previousSlide={this.previousSlide} />
</div>
<div id='InfoSquare'>
<div id='wrapper'>
<div id='item' ref={i=>this.description=i}>LOGO TEE</div>
<div id='description'>Black tee 100% cotton with red silkscreened logo on front and back.</div>
<select id="size2" onChange={this.change} value={this.state.value}>
<option value="medium">Medium</option>
<option value="large">Large</option>
<option value="x-large">X-large</option>
</select>
<button onClick={this.handleClick} className="addit">ADD TO CART</button>
</div>
</div>
</div>
);
}
nextSlide() {
this.setState({ slideCount: this.state.slideCount + 1 })
}
previousSlide() {
this.setState({ slideCount: this.state.slideCount - 1 })
}
}
const mapDispatchToProps = (dispatch) => {
return {
onCartAdd: (cart) => {
dispatch(addCart(cart));
},
}
}
function mapStateToProps(state) {
return {
cart: state.cart
};
}
export default connect(mapStateToProps,mapDispatchToProps)(ProductPage3);
</code></pre>
<p>This is my <code>Cart</code> component:</p>

this.state = {items: this.props.cart,cart: [],total: 0};
}
...

dispatch(removeCart(item));
},
}
}
function mapStateToProps(state) {
return { cart: state.cart };
}
export default connect(mapStateToProps, mapDispatchToProps)(Cart);
</code></pre>
<p>In <code>Cart</code> I'm rendering the item selection data for each object added to the cart. Here is where I want to display the item image also.</p>
<p>Since I have a image slider set up, an example of one of the slides would be:</p>
<pre><code>import React, { Component } from 'react';
import take1 from './DETAIL.png';
const SlideNocHOne= (props) => {
return <img src= {take1} id="slide"></img>
}
export default SlideNocHOne;
</code></pre>
<p>Let's say I want this <code>DETAIL.png</code> image on the <code>Cart</code>, how could I transfer it with the user selection using Redux?</p>
<p>These are my Redux components:</p>
<pre><code>import { createStore, applyMiddleware, compose } from 'redux';

Unable to consume JAVA sdk for Google classroom API's getting PERMISSION_DENIED Request had insufficient authentication scopes

<p>I am new to Google class room and Its been a long time I am trying to integrating this no success so far, need help.</p>
<p>One more thing It says it is mandatory to have a G suite account (I dont get it where it is used, yet I have not created G suit account, is this the reason I am getting exception)</p>
<p>Please let me know If I am suppose to add more details on above senerio.</p>

How do I call my Date Picker from a button press?
|
<p>I am trying to create an app that allows me to pick a date and a table is populated with appointments on that day. I am having troubles with getting the date picker to show.</p>
<p>I have taken a look at this <a href="https://developer.android.com/guide/topics/ui/controls/pickers" rel="nofollow noreferrer">https://developer.android.com/guide/topics/ui/controls/pickers</a> and created a date picker from this code. I want to call that date picker from a button press found in the <code>AddAppointmentActivity</code> class.</p>
<p>Here is my Appointment class:</p>
<pre><code>package com.example.dentdevils.ui.HomeLinks;

}
}
</code></pre>
<p>I did have the classes in separate files but was testing different things hence why they are in the same file (I will move them back out again to separate files after I have managed to call the date picker).</p>
<p>My question is, how would I call the date picker dialog from the button press?</p>

<p>Now that the flag is removed per @Colin Altworth's answer, I get the following error particular to vis-ui (again, updated to use the recommended version for libGDX 1.9.5):</p>

<p>Turns out the rest of the issue was a bug in VisUI- the latest update tries to use the Thread class, which is not supported by GWT.</p>

Gunicorn + Supervisor configuration issue. Django project deployed on amazon ec2 + ubuntu + nginx
|
<p>I've been running a django project on an ubuntu ec2 instance with gunicorn and nginx. I know it was running for at least a couple days with no issues, but I just checked in on it a week after deployment, and it is no longer running. I get a 502 Bad Gateway error when I access the site. I put in my usual gunicorn command,
<code>sudo gunicorn adventure_time.wsgi:application –b 127.0.0.1:8001</code> but all I get is </p>

<p>So... it seems like nothing is running on 127.0.0.1:8000. Nothing for me to kill. (I've also tried <code>sudo pkill gunicorn</code>)Anyone got some tips on what I can do get my site running again? Also, why is it that gunicorn is still trying to connect to port 8000, but in my command I've asked it to connect to 8001? Thanks!!</p>
<p>edit: I think it's more than just gunicorn. I'm also running supervisor, and I feel like that might be part of the issue.</p>
<p>Inside my project folder is <code>gunicorn.conf.py</code></p>
<pre><code>proc_name = "at_api"
bind = '127.0.0.1:8001'
loglevel = "error"
workers = 2
</code></pre>
<p>Inside my <code>/etc/supervisor/conf.d/at_api.conf</code></p>

Why Elixir Guardian (DB) has Problems finding token?
|
<p>I have Problems to understand, how guardian works or handles errors, so in this example, I simply try to logout and get errors on the console..</p>
<p>code:</p>
<pre class="lang-ruby prettyprint-override"><code>def delete(conn, _params) do
{:ok, claims} = Guardian.Plug.claims(conn)
conn
|> Guardian.Plug.current_token
|> Guardian.revoke!(claims)
conn
|> render("delete.json")
end
</code></pre>
<p>Somehow the token is not found even there is the session deleted, the user logged out.
I have problems to debug the code.
How can I find errors or debug the code better?</p>

iOS - AudioFormat issue linking up mixer, remoteio and dynamics processor
|
<p>I'm trying to link up my mixer -> remoteio -> dynamics processor</p>
<p>Here is my AudioFormat
// Describe format</p>
<pre><code>memset( &audioFormat, 0, sizeof(AudioStreamBasicDescription) );
audioFormat.mSampleRate = 44100.00;
audioFormat.mFormatID = kAudioFormatLinearPCM;
audioFormat.mFormatFlags = kAudioFormatFlagIsSignedInteger | kAudioFormatFlagIsPacked;
audioFormat.mFramesPerPacket = 1;
audioFormat.mChannelsPerFrame = 1;
audioFormat.mBitsPerChannel = 16;
audioFormat.mBytesPerPacket = 2;
audioFormat.mBytesPerFrame = 2;
</code></pre>
<p>When I use CAShow it gives me the following. </p>
<pre><code>AudioUnitGraph 0x4725000:

</code></pre>
<p>Trying
result = AudioUnitSetProperty (
_dynamicsUnit,
kAudioUnitProperty_StreamFormat,
kAudioUnitScope_Input,
0,
&audioFormat,
sizeof (audioFormat)
);</p>
<p>to set the audioFormat to the desired format gives me a error code -10868.</p>
<p>I also realised that getting the ASBD from the audynamicsprocessor yields this. </p>
<pre><code>effectASBD AudioStreamBasicDescription
mSampleRate Float64 44100
mFormatID UInt32 1819304813
mFormatFlags UInt32 41
mBytesPerPacket UInt32 4
mFramesPerPacket UInt32 1
mBytesPerFrame UInt32 4
mChannelsPerFrame UInt32 2
mBitsPerChannel UInt32 32
mReserved UInt32 0
</code></pre>
<p>and I tried various things like letting the audioformat ABSD be as per the AUdynamicsprocessor but I get the same error. </p>
<p>I would like to use my original audioformat ASBD as far as possible due to latency considerations. Also, my callback algorithms are already written for that audioformat.
Is this possible? </p>
<p>Thanks in advance. </p>

mySQL returns empty even though it shouldn't?

<p>am a total mySQL newbie, but I have no idea how to search for the answer to this, so that's why I'm bringing it here:</p>

<p>I can get the results for one type of query:</p>

<p>However, changing the p-value that I'm asking for:</p>
<pre><code> SELECT p FROM rParam WHERE p=0.6 GROUP BY p;
Empty set (0.00 sec)
</code></pre>

Issues with time() when running a C musl application in docker container on arm
|
<p>My application is unable to handle time operations like <a href="https://linux.die.net/man/2/time" rel="nofollow noreferrer">time(2)</a> when it runs in alpine docker container on an arm device.</p>
<p>What I have:
I am building a native c application which is statically linked to musl with toolchain from musl.cc (arm-linux-musleabihf-gcc). I am using latest alpine container (without image tag).</p>
<p>How it behaves:</p>
<ul>
<li>Running binary directly on arm device works as expected</li>
<li>Running in alpine container on x64 device works as expected</li>
<li>Running in alpine container on arm device does <strong>not</strong> work</li>
</ul>
<p>What's going wrong:</p>
<ul>
<li><code>time(NULL);</code> returns ((time_t) -1) and error=1: "Operation not permitted"</li>
<li>The timestamps in the log outputs have cranked timestamps</li>
<li>SSH handshake fails because the validity of the remote certificate is in the future.</li>
</ul>
<p>However, if I execute <code>date</code> in container's ash the output is valid. Thus, there seems to be a problem that only occurs in alpine containers on the ARM architecture. Funnily enough, I'm switching from Ubuntu to Alpine as we had <a href="https://bugs.launchpad.net/cloud-images/+bug/1896443" rel="nofollow noreferrer">similar problems</a> there.</p>
<p>Does anyone have any idea what I am doing wrong?</p>
<p>Update #1:
Same problem on ubuntu. So the problem seems to be on any docker basis image but only on arm devices.</p>
<p>Update #2: Here is a minimal example
<strong>TimeTest.c</strong></p>
<pre><code>#include <stdio.h>
#include <string.h>
#include "time.h"
#include "errno.h"
int main()
{
printf("hallo\n");
time_t myTime;
time_t result = time(&myTime);
printf("result: %lld\n", result);
if ((long)result < 0)
{
printf("time() error=%d: %s\n", errno, strerror(errno));
}
else
{
struct tm* tm_info = localtime(&myTime);
printf("Current local time and date: %s\n", asctime(tm_info));
}
return 0;
}

Tons of timeouts from Node.JS Express API hosted on Nginx behind Cloudflare
|
<p>I have a Node.JS Express API (MySQL) hosted on Nginx behind Cloudflare (2 instances running). I'm getting a lot of 504 timeout on Roblox and upstream timed out on Nginx. I have never seen a request I sent with Postman fail. I think it happens more under load. These instances are processing processing 11M requests a week. This is hosted on a 16 core, 64 GB RAM, dedicated server with 2-3 load average</p>
<p><strong>Nginx error log spams these:</strong></p>
<ul>
<li>upstream timed out (110: Connection timed out) while reading response header from upstream</li>
<li>no live upstreams while connecting to upstream</li>
<li>upstream prematurely closed connection while reading response header from upstream</li>
</ul>
<p>The upstream timed out errors are the concern as they are the majority of the errors.</p>
<p>Generally, I don't do too much processing on the API. I have less then a dozen endpoints that are mostly simple DB selects.</p>
<p><strong>Can someone direct me in the right area to resolve this?</strong> Is it my Nginx config, do I need more instances, is it my design, is it Roblox, is it Cloudflare? I read Node.js can handle this (under one instance), so I tried to adjust worker connections in Nginx which caused more no live upstream errors. I cannot wrap my head around what the bottle neck is.</p>

Observable loses value after call to applyBindings
|
<p>I am working on this <a href="http://jsfiddle.net/StrandedPirate/yjhz6bvj/" rel="nofollow noreferrer">fiddle</a> trying to isolate a problem I'm having with the value not being set on a <code>select</code> element and now I'm stuck with nonsensical behavior in jsfiddle. I can't tell if this issue is my underlying problem or if this is a bug in jsfiddle.</p>
<p>First I'm using inheritance with my view models as described here: <a href="http://www.bennadel.com/blog/1566-using-super-constructors-is-critical-in-prototypal-inheritance-in-javascript.htm" rel="nofollow noreferrer">Using Super Constructors Is Critical In Prototypal Inheritance In Javascript </a>. Perhaps this article has led me down the wrong path, I don't know. Bottom line is that I need to do inheritance. </p>
<p>Second the problem with this particular fiddle is that after the call to <code>ko.applyBindings</code> my observable just loses its value (becomes <code>undefined</code>) and then out of no where gets set to <code>1</code>.</p>
<p><img src="https://i.stack.imgur.com/0EOUZ.png" alt="enter image description here"></p>
<pre><code>function userAddressModelBase(data) {
var self = this;
self.states = ko.observableArray(data.states);
}
userAddressModel.prototype = new userAddressModelBase({});
userAddressModel.constructor = userAddressModel;
function userAddressModel(data) {
var self = this;
userAddressModelBase.call(self, data);
self.sampleText = ko.observable("i'm here");
console.log("data.selectedStateId is: " + data.selectedStateId);
self.selectedStateId = ko.observable(data.selectedStateId);
console.log("self.selectedStateId is: " + self.selectedStateId());
self.getStates = function () {
console.log("getStates running...");
window.setTimeout(function () {
console.log("getStates callback...");
self.states([new stateModel({
id: 1,
name: "New York"
}), new stateModel({
id: 2,
name: "Texas"
}), new stateModel({
id: 3,
name: "California"
}), new stateModel({

name: "Ohio"
})]);
console.log(ko.toJS(self));
console.log("getStates callback self.selectedStateId is: " + self.selectedStateId());
}, 1000);
};
//console.log("self.selectedStateId is: " + self.selectedStateId());
//self.getStates();
//console.log("self.selectedStateId is: " + self.selectedStateId());
}
function stateModel(data) {
var self = this;
self.id = ko.observable(data.id);
self.name = ko.observable(data.name);
}
var model = new userAddressModel({ selectedStateId: 3 });
console.log(ko.toJS(model));
console.log("before applyBindings model.selectedStateId is: " + model.selectedStateId());
console.log("appling bindings...");
ko.applyBindings(model); // selectedStateId is now undefined!!!
console.log("appling bindings finished.");
console.log(ko.toJS(model));
console.log("after applyBindings model.selectedStateId is: " + model.selectedStateId());
model.getStates(); // selectedStateId is now 1 after this finishes!!!

What is the best way to write a switch statement to return an image depending on a number without repeating to much code?
|
<p>I have a switch statement that returns an image based on the case number. I have 8 images of water droplets that start off as an empty droplet(drop_empty) and when the number increases from 1...6 and so on as shown in my code I want to change the images. For the 8 images as shown in the screenshot, I have each one set in an @IBOutlet and in an array in order to choose what image get's assigned to what. I do feel that I'm repeating my self way too much and am hoping to find a better solution to shorten my repetition.
Hopefully, my code makes more sense.</p>

How do I return columns from different table using SQLAlchemy, Flask?

Selenium grid launching browser on hub instead of node
|
<p>I have configured my hub and one of the node. Hub is setup on jenkins as a plugin which is running on ubundu machine and my node is running on windows machine.
Hub and node are correctly configure.
Now when I am running the test to launch the chrome browser on node it is behaving weird.
The one browser instances is launched on the node and not redirected to url.
After few seconds it launches the Firefox browser's 5 instances on hub node. (Although i have setup only chrome capabilities). </p>

<p>There is a problem in template function because data object doesn't have all data. I noticed that has problem with nested data (field like type, trigger, process has null or string ("[object Object]") values.)</p>
<p>How can I solve this problem ?</p>

Validating value of a Certain key before adding it to a c# dictionary
|
<p>I am trying to implement a dictionary in such a way that It will only add in a certain value to a key if that <strong>new value</strong> is greater than the <strong>currently existing value</strong></p>
<p>So the basic scenarios would be:</p>
<ol>
<li>If the key is not available, it will create a new key and a value</li>
<li>If the key if available, it will check if the current value is greater than the value that is already assigned to that key and will only update if it is greater.</li>
</ol>
<p>Before I explain the problem I am facing here is my code</p>
<pre><code>static IDictionary<string, string> versionStack = new Dictionary<string, string>();
</code></pre>
<pre><code>foreach(var item in RequiredApps)
{
nameOfApp = item.Key;
minimumVersionOfApp = item.Value.minVersion;
if (versionStack.TryGetValue(nameOfApp, out minimumVersionOfApp))
{
if (Convert.ToInt32(minimumVersionOfApp) >= Convert.ToInt32(item.Value.minVersion))
minimumVersionOfApp = item.Value.minVersion;
}
versionStack[nameOfApp] = minimumVersionOfApp;
}
</code></pre>
<p><strong>Note:</strong> Kindly do not worry about the <code>for</code> loop as it works fine and gives no problem there. Just want to display only the specific code that gives me problem</p>
<p>Right now I have been able to fulfill the functionality to a certain level but the problem is when the <code>TryGetValue</code> is executed it turns all my values to null.</p>
<p>I am using the <code>TryGetValue</code> to see if a key has a value and if so to retrieve it.</p>
<p>I am stuck here right now and would appreciate if anyone can help show me what I am doing wrong.</p>
<p><strong>Edit :-</strong></p>
<p>Given that the problem I am facing is quite unclear and as suggested by Rufus L I am adding a sample dummy application with exactly the problem I am facing</p>
<p>Hope this helps to clear any confusion :)</p>

getImageData returns white image
|
<p>I need to read the image data from an image object in javascript.
But my code returns always a blank array (set to 255) </p>
<pre><code><html>
<header>
</header>
<body>
<input type="file" id="imgfile" onchange="testImageData(event);" />
<canvas id="canvas1" width="640" height="480"></canvas>
<script src="./../scripts/cam.js" ></script>
</body>
</html>
</code></pre>
<p>Here is the script</p>
<pre><code>var canvas1 = document.getElementById('canvas1');
var context1 = canvas1.getContext('2d');
function getImageData(image){
/*
returns Uint8ClampedArray object
takes an image obj
*/
var canvas = document.createElement("canvas");
canvas.height = image.height;
canvas.width = image.width;
var ctx = canvas.getContext("2d");
ctx.width = image.width;
ctx.height = image.height;
ctx.drawImage(image,0,0);
return ctx.getImageData(0, 0, ctx.width, ctx.height);
}
function testImageData(event){
var selectedFile = event.target.files[0];
var reader = new FileReader();
var img = new Image();
reader.onload = function(event) {
console.log('onload');
img.src = event.target.result;
img.onload = function(){
context1.drawImage(img, 0,0, img.width, img.height);
var imgData = getImageData(img);
// console.log(imgData);
var data = imgData.data;
for(var i = 0; i<data.length;i+=4){
console.log(data[i],data[i+1],data[i+2],data[i+3]);
}
}
};
</code></pre>
<p>
In my understanding, the console.log should return me the data in RGBA.
But I'm just getting 255.</p>
<p>
<a href="https://i.stack.imgur.com/f5rKU.png" rel="nofollow noreferrer">console.log output</a></p>
<hr>
<h2>EDIT:</h2>
<p>Okay I found a work around but I don't understand why this is working.<br>
Instead using getImageData, I get the data directly from the drawn context1. </p>
<pre><code>function testImageData(event){
var selectedFile = event.target.files[0];
var reader = new FileReader();
var img = new Image();
reader.onload = function(event) {
console.log('onload');
img.src = event.target.result;
img.onload = function(){
context1.drawImage(img, 0,0, img.width, img.height);
var imgData = context1.getImageData(0,0,img.width,img.height);
var data = imgData.data;
for(var i = 0; i<data.length;i+=4){
console.log(data[i],data[i+1],data[i+2],data[i+3]);
}
}
};
</code></pre>
<p>So the problem must lie in creating a new canvas.</p>

Js/jQuery - How to hide/show an input created on the fly?
|
<p>This code creates a group of elements (four inputs) on the fly. Once you create an element (four inputs) you can select/deselect, when you select an element will bring up the editor for the corresponding element. I've made a function to hide only the first element. The problem is that I can not make it comeback without affecting the other elements. </p>
<p>Instructions:</p>
<p>Click on the "Price" link, an element will be created on the fly (four nested inputs)
Select the element (four nested inputs) to bring up the editor ( one input and a brown little square).
Click on the little brown square to hide the first input of the element (four nested inputs) and that will hide the first input.
I need the little brown square to hide and show the same input.</p>
<p>Go here to see the full code:
To see the problem you have to create more than one element to find out.</p>
<p><a href="http://jsfiddle.net/yjfGx/13/" rel="nofollow">http://jsfiddle.net/yjfGx/13/</a></p>

<p>Now, since my User will belong to a single country, in the database it has a foreign key reference to the Country table. In my model, I set the Country property to be of type int. Is this correct?</p>
<p>How would I correctly set this up so a dropdownlist is shown for choosing a country in the View but a numerical value is saved for persistance to the database?</p>

jQuery mobile getting wrong authentication
|
<p>I have the following situation:</p>
<p>index.html (which is my login page)</p>
<pre><code><div data-role="page" id="page_login">
<div id="wrapper_top_image">
<div id="top_image"></div>
</div>
<div data-role="content" data-theme="b">

<form id="loginForm" onsubmit="return submitLogin();">
<div data-role="fieldcontain" class="ui-hide-label">
<label for="username">Username:</label>
<input type="text" name="username" id="username" value="" placeholder="Username" />
</div>
<div data-role="fieldcontain" class="ui-hide-label">
<label for="password">Password:</label>
<input type="password" name="password" id="password" value="" placeholder="Password" />
</div>
<input type="submit" value="Login" id="submitButton">
</form>
</div>
</div>
<div data-role="footer">
<h4>&copy; 2013 Company</h4>
<h6>Developed by Alex</h6>
</div>
</code></pre>
<p></p>
<p>and then my PHP Script that is going to check everything -> ps.. I fixed to avoid injection already! :</p>
<p>auth.php</p>
<pre><code>$mysqli = new mysqli($mysql_hostname,$mysql_user, $mysql_password, $mysql_database);
// Parse the log in form if the user has filled it out and pressed "Log In"
if (isset($_POST["username"]) && isset($_POST["password"])) {
$username =$_POST['username'];
$password =$_POST['password'];
$sql = "SELECT id, password, username FROM users WHERE username='$username' AND password='$password' LIMIT 1";
$result = $mysqli->query($sql) or die( $mysqli->error() );
$rowN= mysqli_num_rows($result);
if($rowN==1){
$response_array['status'] = 'success';
} else {
$response_array['status'] = 'error';
}
echo json_encode($response_array);
}
$mysqli->close();
</code></pre>
<p>Finally my JQuery Script:</p>
<pre><code>function submitLogin(){
jQuery.support.cors = true;
$.ajax({
url: 'http://www.xxxx.com/mobile/auth.php',
crossDomain: true,
type: "post",
data: $("#loginForm").serialize(),
success: function(data){
if(data.status == 'success'){
//alert("Granted Access!");
$.mobile.changePage("main.html");
}else if(data.status == 'error'){
alert("Authentication Invalid. Please try again!");
navigator.app.exitApp();
$.mobile.changePage("index.html");
}
}
});
};
</code></pre>
<p>Everything is working ok! Data is checked and if it is okay, is redirected to main.html (main page) otherwise the app pops up a window saying that the authentication is wrong, keeping the user in the same page.</p>
<p>Here is the dilemma: If users type the wrong credential trying to login again, any credential that he/she enter will be considerate invalid even if he/she entered the right one and the app will keep going back to the login page until I refresh the browser or end the app in case of running in the device.</p>
<p>Does anyone knows what may be happening?</p>

AngularJS: Setting up default input values when the page is initially loading

<p>I am developing an web app with AngularJS & Bootstrap. In my application there is a bootstrap modal on main dashboard. This modal is showing up on a toggle button. In the main dashboard there are some charts & grids. The input fields for drawing these charts and grids are coming from that modal.</p>
<p>This is the main dashboard html.</p>

<p>When the page is loading it calls <strong>initModal</strong> function & populate all the drop down field in the modal. But actually I am getting an empty page, them I toggle the modal I can select fields an clicks the submit button, then it draws charts. Initially it doesn't draw any graph or grid. The thing I really want is show main page with charts, those charts should be drawn for default input fields(when the modal is loading default values are the first element in the drop down). Again, once I select new values from the modal & submit it should reload the main page with new charts based on newly selected values.</p>
<p>Hope you clear what I am mentioning. Any suggestions would be highly appreciated.</p>

java.util.Scanner object throws NullPointerException while parsing text file
|
<p>I created this JAVA code for <a href="https://code.google.com/codejam/contest/544101/dashboard#s=p0" rel="nofollow">this Google Code Jam question</a>.
When i execute the code and select <a href="https://code.google.com/codejam/contest/544101/dashboard/do/A-large-practice.in?cmd=GetInputFile&problem=567116&input_id=1&filename=A-large-practice.in&redownload_last=1&agent=website&csrfmiddlewaretoken=NGRhMjVlNjE3N2IwODc4Yzk5YTBkYzNmODYzNTVlYjV8fDE0MjIyNzc3MjE1NDQ5Njk%3D" rel="nofollow">this text file</a>, it throws NullPointerException. Please help. I guess it is because nextLine() positions the scanner to the nextLine and returns the rest of the current line which is empty.</p>
<pre><code> line = ab.nextLine();
</code></pre>
<p>How do I fix this error so that it reads the next line of text? Provide code along with your suggestions. I will be grateful to you for the rest of my life :)</p>

Docker: Connected as id undefined. Error trying to establish connection between database container and backend container

How to mock newly created objects inside Presenters method?
|
<p>I have PaymentPresenter with method payWorkOrder(). That method accepts some parameters and based on the logic created two new objects:</p>
<ol>
<li>WoPayment</li>
<li>PaymentRequest</li>
</ol>
<p>Here is the code for that:</p>
<pre><code>@RunWith(PowerMockRunner.class) @PrepareForTest({TextUtils.class, WoPayment.class, PaymentRequest.class})
public class PaymentPresenterTest extends BaseTest {
@Rule TrampolineSchedulerRule trampolineSchedulerRule = new TrampolineSchedulerRule();
@Mock CustomersRepository customersRepository;
@Mock AgreementsRepository agreementsRepository;
@Mock WorkOrdersRepository workOrdersRepository;
@Mock PaymentPresenter.View view;
@Mock ResponseBody responseBody;
private PaymentPresenter presenter;
@Before public void setUp() {
mockTextUtils();
presenter = new PaymentPresenter(customersRepository, agreementsRepository, workOrdersRepository);
presenter.setView(view);
}
public void payWorkOrderInvoice(int workOrderId, double amount, String paymentMethod, String checkNumber) {
disposables = RxUtil.initDisposables(disposables);
WoPayment woPayment = new WoPayment();
if(amount > 0) {
woPayment.setAmount(amount);
} else {
view.displayAmountShouldBeGreaterThanZero();
return;
}
if(TextUtils.isEmpty(paymentMethod)) {
view.displayPaymentMethodInvalid();
return;
} else {

}

view.displayWorkOrderInvoiceNotPaid();
}
}, throwable -> {
view.enablePayButton();
view.handleError(throwable);
});
disposables.add(disposable);
}
}
}
</code></pre>
<p>Here is my unit test:</p>
<pre><code>@Test public void shouldPayWorkOrderInvoice() {
// Given
int workOrderId = 1;
double amount = 1.0;
String paymentMethod = "cash";
String checkNumber = "1";
WorkOrderDetails workOrderDetails = Mockito.mock(WorkOrderDetails.class);
Response<WorkOrderDetails> response = Response.success(200, workOrderDetails);
WoPayment woPayment = new WoPayment();
woPayment.setAmount(amount);
woPayment.setCheckNumber(checkNumber);
woPayment.setPaymentMethod(paymentMethod);
PaymentRequest paymentRequest = new PaymentRequest(woPayment);
// When
Mockito.when(workOrdersRepository.payWorkOrderInvoice(workOrderId, paymentRequest)).thenReturn(Single.just(response));
presenter.payWorkOrderInvoice(workOrderId, amount, paymentMethod, checkNumber);
// Then
Mockito.verify(view).displayWorkOrderInvoicePaid(workOrderDetails);
}
</code></pre>
<p><strong>It throws exception here:</strong></p>
<pre><code>Disposable disposable = workOrdersRepository.payWorkOrderInvoice(workOrderId, new PaymentRequest(woPayment))

Unable to send Array to correct destination processor in MPI

mask = xor(mask,(int)pow((double)2,i));
//printf("After xor rank is %d and mask is %d\n",rank,mask);
if(and(my_id, mask) == 0){
if(and(my_id,(int) pow((double)2,i)) == 0){
dest = xor(my_id,(int) pow((double)2,i));

Unable to Use String Result From AJAX Request

Array size issue for converting String to Unicode
|
<p>I have a string "text" in one class which calls on a method in another class to convert text in various ways. In this method though I am left with an "ArrayIndexOutOfBoundsException" error.</p>
<pre><code>public String toUnicode() {
char unicodeTextArray[] = new char[text.length()];
if (text == null || text.isEmpty()) {
return "";
}
String unicodeTextArrayString[] = new String[text.length()];
for (int i = 0; i < text.length(); i++) {
unicodeTextArray[i] = text.charAt(i);
if (unicodeTextArray[i] < 0x10) {
unicodeTextArrayString[i] = "\\u000" + Integer.toHexString(unicodeTextArray[i]);
} else if (unicodeTextArray[i] < 0x100) {
unicodeTextArrayString[i] = "\\u00" + Integer.toHexString(unicodeTextArray[i]);
} else if (unicodeTextArray[i] < 0x1000) {
unicodeTextArrayString[i] = "\\u0" + Integer.toHexString(unicodeTextArray[i]);
}
unicodeTextArrayString[i] = "\\u" + Integer.toHexString(unicodeTextArray[i]);
}
String unicode = unicodeTextArrayString[text.length()];
return unicode;
}
</code></pre>
<p>Changing one line to an arbitrarily large number such as:</p>
<pre><code>String unicodeTextArrayString[] = new String[9999];
</code></pre>
<p>Results in no error, but it returns null. </p>
<p>I thought about setting an int variable to increase the length of the array, but * 4 was still too small of an array size and it seems like if I go too large it just returns null.</p>
<p>How could I go about getting the correct length of the array?</p>
<p>EDIT: I found a non-array approach that works, but I would still like to know if there is a way to make the above array approach work in some way.</p>
<pre><code>public String toUnicode()
{
String unicodeString = "";
for (int i = 0; i < text.length(); i++)
{
char c = text.charAt(i);
String s = String.format ("\\u%04x", (int)c);
unicodeString = unicodeString + s;
}
return unicodeString;
}
</code></pre>
<p>EDIT 2: In case anyone reading this is curious, to get the decimal value of the unicode:</p>
<pre><code> public String toUnicode()
{
String unicodeString = "";
for (int i = 0; i < text.length(); i++)
{
char c = text.charAt(i);
int unicodeDecimal = c;
unicodeString = unicodeString + unicodeDecimal + " ";
}
return unicodeString;
}
</code></pre>
<p>EDIT 3: I ended up deciding to use the following, which separates unicode decimals by space, and checks for the unicode value 10 (which means new line) and outputs a new line into the string instead of that value.</p>
<pre><code> public String toUnicode()
{
String unicodeString = "";
for (int i = 0; i < text.length(); i++)
{
char c = text.charAt(i);
int unicodeDecimal = c;
if (unicodeDecimal == 10)
{
unicodeString = unicodeString + "\n";
}
else
{
unicodeString = unicodeString + unicodeDecimal + " ";
}
}
return unicodeString;
}

QML Progress Bar doesn't move
|
<p>I am using QT v5.12.6 and in my application i am planning to use Progress Bar during application bootup for around 15secs. In this 15secs operations like:</p>
<ol>
<li>QML components creation.</li>
<li>connection with the server.</li>
<li>Other bootup operations will be running in the background.</li>
</ol>
<p>Once, all the bootup operation is done i will hide my splash screen which is just a Rectangle which includes Loading text with a progress bar. For this 15 secs i will be incrementing the progress bar but the progress bar doesn't increment/move for some 10 secs. It looks like it is hanged, but if i use a busy indicator it starts to rotate. Unfortunately, i can't use busy indicator component as i need a look and feel like a progress bar.</p>
<p>My application runs on a embedded platform which has low end processor and very less RAM speed. I am assuming this problem is due to the Load on the UI as many components is getting created.</p>
<p>Is there any difference between busy indicator and Progress bar and also any suggestions on how to handle UI load on the bootup ?</p>
<p><strong>Edit 1:</strong> Added an example. I have tried my level best to mimic the problem. In this example both the busyindicator and Progress bar is getting stuck for sometime. But in the embedded device Busy indicator works but no idea how. After running the application Please click on <strong>Click Me</strong> button.</p>

What is the difference between "Persistent Class" and "Entity" in JPA or in Hibernate?
|
<p>First things first:</p>
<ol>
<li>I'm aware of <a href="https://stackoverflow.com/questions/28372601/what-is-the-difference-between-entity-and-persistent-class">this</a> question, which, at the high level of abstraction, asks same what I ask here; however, I find it (and its answer) lacking, therefore, I would like to elaborate on this topic here;</li>
<li>I would kindly ask anyone, who has a good understanding of the <em>formal definitions</em> in the JPA and Hibernate, to help me clarify this mess.</li>
</ol>
<p>Disclaimer: I am not looking for the basic explanations of what the Entity is and how to use it. I am using Hibernate/JPA for quite some time now.</p>
<p>My question is more about <em>formal definitions</em>, in order to clarify the distinctions of the formal semantics (definitions) between <em>Entity</em> and <em>Persistent Class</em>, to make it crystal-clear how one differs from another and how they are defined.</p>
<p>Initially, I expected the answer to be found in <a href="https://download.oracle.com/otn-pub/jcp/persistence-2_2-mrel-spec/JavaPersistence.pdf" rel="nofollow noreferrer">JSR 338: JPA Specification 2.2</a> and <a href="https://docs.jboss.org/hibernate/orm/5.0/manual/en-US/html/" rel="nofollow noreferrer">Hibernate 5.0.0 Reference Documentation</a>, but I got quite confused, as I was left with a feeling, that, in this context, both documents are lacking, leaving a big room for these concepts/definitions to overlap and introduce some speculations.</p>
<hr />
<h2>Let's start with JSR 338: JPA 2.2 Specification:</h2>
<p>For some (very strange to me) reason, in this entire specification, keyword phrases "Persistent Object" and "Persistent Class" are not found, to wit, they are found only once and twice respectively:</p>
<blockquote>
<ul>
<li><em>Persistent Object</em> - found in the Javadoc comment, saying nothing interesting (page 221)</li>
<li><em>Persistent Class</em> - found in the xsd documentation, again, saying nothing much (pages: 378, 529)</li>
</ul>
</blockquote>
<p>and, unfortunately, that is it in this specification, nothing more at all.</p>
<p>The <em>Entity Class</em>, on the other hand, is defined as follows:</p>
<blockquote>
<p>An entity is a lightweight persistent domain object. The primary programming artifact is the entity class. An entity class may make use of auxiliary classes
that serve as helper classes or that are used to represent the state of the entity.</p>
</blockquote>
<p>which, again, I find extremely lacking for the formal specification document, but at least, this says that it is a <em>persistent domain object</em>.</p>
<p>In the same document, <em>Entity</em> is also defined as a Class (2.1 The Entity Class, page 23).</p>
<p>Even though this might not seem important, it's quite confusing whether it's defined as a <em>Persistent Object</em> or as a <em>Class</em>.</p>
<p><strong>My conclusion based on this specification document:</strong></p>
<ol>
<li><em>Persistent Class/Object</em> is not defined in the JPA 2.2 Specification at all;</li>
<li><em>Entity</em> is defined as <em>persistent object</em>, <strong>and(!)</strong>, as a <em>Class</em>, which is really unclear to me;</li>
</ol>
<p>In my conceptual understanding, <em>Persistent Object</em>, sounds very much as an object, which is persist<em>able</em> <strong>if(!)</strong> it will be mapped correspondingly; hence, <em>Persistent Class</em> - as a <em>Class</em>, instances of which are possible to get persisted (i.e. they can be stored into database layer, by conforming to POJO concept), if the class is mapped accordingly. I.e. <em>Persistent Class</em> is a persist<em>able</em> class, and it transforms to <em>Entity</em>, if it has its corresponding mapping definition (either with .hbm.xml or JPA annotations).</p>
<hr />
<h2>Hibernate 5 Reference Documentation</h2>
<p>On the other hand, Hibernate <a href="https://docs.jboss.org/hibernate/orm/5.0/manual/en-US/html/ch04.html" rel="nofollow noreferrer">defines</a> <em>Persistent Classes</em>, and it does this as follows:</p>
<blockquote>
<p>Persistent classes are classes in an application that implement the entities of the business problem (e.g. Customer and Order in an E-commerce application). The term "persistent" here means that the classes are able to be persisted, not that they are in the persistent state.</p>
</blockquote>
<p>Am I getting this correct, that <em>Persistent Classes implement the entity</em> means, that my upper understanding is correct, and <em>Persistent Class</em> is just a Java class, which implements the <em>Entity</em> model (without mapping), and in conjunction with its mapping (.hbm.xml or JPA) it becomes an <em>Entity</em>? is <em>Persistent Class + Mapping Definition = Entity</em> correct?</p>
<hr />
<p>I would also plug here in some snippets from the <a href="https://www.manning.com/books/java-persistence-with-hibernate-second-edition" rel="nofollow noreferrer">Java Persistence with Hibernate, Second Edition</a> book:</p>
<blockquote>
<p>You wrote a persistent class and its mapping with annotations. - (Summary 2.4);</p>
</blockquote>
<p><em>kind of, differentiates persistent class from its mapping, and that, again, sort of supports the idea, that persistent class and its mapping are distinct concepts, which logically brings the point, that persistent class alone, is not an Entity.</em></p>
<blockquote>
<p>The persistent classes are unaware of—and have no dependency on—the persistence mechanism. - (Chapter 3.2);</p>
</blockquote>
<p><em>clearly states, that Persistent Classes are unaware of the persistence mechanism.</em></p>
<blockquote>
<p>You can reuse persistent classes outside the context of persistence, in unit tests or in the presentation layer, for example. You can create instances in any runtime environment with the regular Java new operator, preserving testability and reusability. - (Chapter 3.2).</p>
</blockquote>
<p><em>also supports the idea, that Persistent Class is not necessarily a mapped Entity.</em></p>
<p><strong>My conclusion:</strong><br>(based on my initial understanding, which seems to be supported by "Hibernate Reference Documentation" and "Java Persistence with Hibernate, Second Edition" book.)</p>
<p><em>Persistent Classes</em> are Java classes, which (if needed!) would be conforming with the JPA Specification (according to which, they need to be POJOs and they can be mapped), but they are not Entities if they are not mapped, and they can be used in the outside-of-JPA context, to just operate on them as on ordinary Java objects, or even to present them at the Presentation Layer.</p>
<hr />
<h2>Finally:</h2>
<p>As you can see, my question is a bit of a mixture of different resources, showing my evident confusion, as I cannot clearly define the <em>formal</em>, so called <em>scientifically adopted</em> definitions for these two concepts.</p>
<p>Can we clearly define what is the <em>Persistent Class</em>, what is <em>Entity</em>, and what is the the <em>semantic</em> and <em>definitive</em> difference/overlapping between them in terms of JPA and Hibernate?</p>

Angular 2 - http.get never being call
|
<p>Im learning Angular 4 and have run into a problem that I cannot seem to find a solution to. Here is the context:
I have a simple app that displays info about US Presidents.
The backend is a rest API provided by webapi...this works fine.
The front end is an Angular app.</p>
<p>Ive distilled the problem down to 3 components, 1 data service and 1 model.
Here is the model:</p>
<pre><code>export class President {
constructor(
public id: number,
public presidentName: string,
public presidentNumber: number,
public yearsServed: string,
public partyAffiliation: string,
public spouse: string) {}
}
</code></pre>
<p>The 3 components are
1. SearchComponent
2. HomeComponent
3. PresidentComponent</p>
<p>When the app bootstraps, it loads the ApplicationComponent - it is the root component:</p>
<pre><code>import { Component, ViewEncapsulation } from '@angular/core';
@Component({
selector: 'my-app',
template: `
<search-component></search-component>
<home-component></home-component>
`
})
export class ApplicationComponent {}
</code></pre>
<p>PresidentComponent is a child component of HomeComponent. When home component loads, it makes an http call to the api to get a list of presidents and renders 1 presidentComponent for each row returned. This works fine.</p>
<p>What Im trying to do is implement a search feature where the dataService exposes an EventEmitter and provides the search method as shown here:</p>
<pre><code>import { Injectable, EventEmitter, Output } from '@angular/core'
import { President } from '../models/President'
import { Http } from '@angular/http';
import 'rxjs/add/operator/toPromise';
import 'rxjs/add/operator/map';
import { Observable } from 'rxjs/Observable';
@Injectable()
export class DataService {
constructor(private http: Http) {
}
searchEvent: EventEmitter<any> = new EventEmitter();
// simple property for the url to the api
get presidentUrl {
return "http://localhost:51330/api/presidents";
}
search(params: any): Observable<President[]> {
let encParams = encodeParams(params);
console.log(encParams);
return this.http
.get(this.presidentUrl, {search: encParams})
.map(response => response.json());
}
getParties(): String[] {
return ['Republican', 'Democrat', 'Federalist', 'Whig', 'Democratic-Republican', 'None'];
}
getPresidents(): Observable<President[]> {
return this.http.get(this.presidentUrl)
.map(response => response.json());
}
}
/**
* Encodes the object into a valid query string.
* this function is from the book Angular2 Development with TypeScript
*/
function encodeParams(params: any): URLSearchParams {
return Object.keys(params)
.filter(key => params[key])
.reduce((accum: URLSearchParams, key: string) => {
accum.append(key, params[key]);
return accum;
}, new URLSearchParams());
}
</code></pre>
<p>The Search Component houses the search form and when the search button is clicked, it executes the onSearch() function and calls emit on the data service:</p>
<pre><code>onSearch(){
if(this.formModel.valid){
console.log('emitting event from search.ts');
this.dataService.searchEvent.emit(this.formModel.value);
}
}
</code></pre>
<p>Then, in the HomeComponent, I want to subscribe to this event and execute a search via the dataservice when it fires:</p>
<pre><code> ngOnInit(): void {
//when component loads, get list of presidents
this.dataService.getPresidents()
.subscribe(
presidents => {
console.log('sub');
this.presidents = presidents;
},
error => console.error(error)
)
//when search event is fired, do a search
this.dataService.searchEvent
.subscribe(
params => {
console.log('in home.ts subscribe ' + JSON.stringify(params));
this.result = this.dataService.search(params);
},
err => console.log("cant get presidents. error code: %s, URL: %s"),
() => console.log('done')
);
}
</code></pre>
<p>When I run this in the browser, everything works except the http call is never executed. If I subscribe() to the http.get call in the dataservice itself, it executes but why should I have to do that when I have a subscription being setup on the HomeComponent?
I want to handle the Observable in the HomeComponent and update the list of presidents that is being displayed in the UI based on the search result.
Any advice is greatly appreciated.</p>

<p>Basically, I have the 'map' object, which has a unique number associated with it. The map object has a 'link' to 1 or more 'commonNumber' objects, which store a 'common' number.</p>
<p>The idea is to be able to map lots of common numbers to a unique number using the JPQL and 'Dao's.</p>
<p>However, when I deploy my java WAR file, I get this error:</p>

<p>I'm at a bit of a loss here...I've tried fiddling around with different ways to map the 'common' object to the 'map' object, but I keep getting errors.</p>
<p>Would anyone be able to shed some light on this for me?</p>

Geolocation directs to building entrance and not defined LatLng
|
<p>I am currently adapting and cleaning up a very simple Google Maps application for users to get walking directions from their current location (determined by GeoLocation) to preset markers designating artworks that are defined with specific LatLng values to the sixth decimal.</p>
<p>There is still a lot of extraneous code in the example that needs to be removed, but the core function is working as expected - almost.</p>
<p>When the user selects a destination from the values supplied in a dropdown menu and hits enter, a lined path appears from where they are to the selected destination - using the calcRoute function. </p>
<p>However, the path is consistently directing the user to the nearest building entrance - which in some cases is several hundred feet away from the LatLng defined in the code. This does not appear to be random inaccuracy, as the path always ends at a building entrance.</p>
<p>I am sure this is a very simple mistake I am making, but I haven't found any posts that seem to address this odd behavior.</p>
<p>I am using Windows 8 and Chrome at the moment for the base development in an attempt to get a working version and then test on other browsers. I appreciate any advice, and will supply all the example code if needed. Here is a sample of some of the typical lines in this app:</p>
<pre><code><script src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true">
</script>
<script>
var locTreeWrapIII = new google.maps.LatLng(48.006640, -122.203680);
</script>
// Tree Wrap III
var markerTreeWrapIII = new google.maps.Marker({
map: map,
position: locTreeWrapIII,
title: 'Tree Wrap III'
});
var infoTreeWrapIII = new google.maps.InfoWindow({ // info window
maxWidth: 400,
content:
'<img alt="" src="https:\/thumbnail-clothespins.jpg" />' +
'<strong>' + markerTreeWrapIII.title + '<\/strong><br \/><br \/><br \/>
<a href="http:\/\/xx\/tree-wrap-iii">Read more about Tree Wrap III</a>'
});
google.maps.event.addListener(markerTreeWrapIII, "click", function () {
document.getElementById('end').value = "(48.006500,-122.203500)";
infoTreeWrapIII.open(map, markerTreeWrapIII);
infoTreeWrapIII.setZIndex(999);
});
google.maps.event.addListener(markerTreeWrapIII, "dblclick", function () {
map.panTo(locTreeWrapIII);
});
google.maps.event.addListener(infoTreeWrapIII, "closeclick", function () {
infoTreeWrapIII.setZIndex(1);
infoTreeWrapIII.close();
});
function calcRoute() {
// Retrieve the start and end locations and create
// a DirectionsRequest using WALKING directions.
var start = document.getElementById('start').value;
var end = document.getElementById('end').value;
var request = {
origin: start,
destination: end,
travelMode: google.maps.TravelMode.WALKING
};
// Route the directions and pass the response to a
// function to create markers for each step.
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
function attachInstructionText(marker, text) {
google.maps.event.addListener(marker, 'click', function () {
// Open an info window when the marker is clicked on,
// containing the text of the step.
stepDisplay.setContent(text);
stepDisplay.open(map, marker);
});

JOGL Native Crash
|
<p>I am running a JOGL based application, and it has been crashing when I perform certain drawing operations. However, The line it crashes on is a call to <code>gl.glGenLists(1)</code>, so I'm not really sure how this could cause an error in the underlying application, since this line is a trivial line (unless the stack is in some sort of bad state - is that possible?).</p>
<p>I also tried updating my video card drivers and now it just freezes in the same place instead of crashing.</p>
<p>The relevant part of the crash report is below. Any help would be appreciated. I'm running an NVIDIA Quadro NVS 160M video card. Thanks.</p>

Pytorch : Neural network is not learning at all
|
<p>I'm new to deep learning so I might just miss something stupid.</p>
<p>I'm training several neural networks on trees. I'm trying to generate trees with my neural networks, and I have a reward function to select the best trees after each generation. I try to learn on the 100 best trees, but when I try to learn, my loss is computed correctly but it's constant even after several <code>optimizer.step()</code>. I honestly have no idea why it's not working. I'm using <code>torch.nn.CrossEntorpyLoss</code> and <code>torch.optim.SGD</code>.

Pandas IndexingError - Unalignable boolean Series provided as indexer (index of the boolean Series and of the indexed object do not match)

<p><strong>Background:</strong> I have a function that calls a pandas dataframe called <code>df</code>. I do various manipulation and clean-up on the <code>df</code> before it becomes <code>exceptions_report</code> (still a pandas dataframe).</p>

<p><strong>Things to note:</strong> I have tried and been able to run the problem piece of code with a much smaller <code>df</code>, so I know something else in this function is causing the issue.</p>

Providing access to EFS from ECS task
|
<p>I am struggling to get an ECS task to be able to see an EFS volume.
The terraform config is:</p>
<p><strong>EFS DEFINITION</strong></p>
<pre><code>resource "aws_efs_file_system" "persistent" {
encrypted = true
}
resource "aws_efs_access_point" "access" {
file_system_id = aws_efs_file_system.persistent.id

for_each = {for net in aws_subnet.private : net.id => {id = net.id}}
file_system_id = aws_efs_file_system.persistent.id
subnet_id = each.value.id
security_groups = [aws_security_group.efs.id]
}
</code></pre>
<hr />
<p><strong>TASK DEFINITION</strong></p>
<pre><code>resource "aws_ecs_task_definition" "app" {
family = "backend-app-task"

}
}
}
}
</code></pre>
<hr />
<p><strong>SECURITY GROUP</strong></p>
<pre><code>resource "aws_security_group" "efs" {

}
</code></pre>
<p>As I understand the AWS docs, the IAM role should have access, and the security group should be passing traffic, but the error suggests that the task cannot resolve the EFS instance.</p>
<p>The error message is:</p>
<pre><code>ResourceInitializationError: failed to invoke EFS utils commands to set up EFS volumes: stderr: Failed to resolve "fs-0000000000000.efs.eu-west-2.amazonaws.com" - check that your file system ID is correct.
</code></pre>
<p>I've manually confirmed in the console that the EFS id is correct, so I can only conclude that it cannot resolve due to a network/permissions issue.</p>

My GitHub Action's GitHub API calls start failing after a period of time

<p>Yesterday I successfully ran this GitHub action several times, but now it is failing with an HTTP Not Found error.

Can't get property from object when redirecting with "Header" function
|
<p>I'm trying to display a inserted product after it is inserted. It looks like the object is empty.</p>
<p>This is what I use to redirect ('Inventario' controller)</p>
<pre><code>public function insertarAction(){
// insertarProducto returns true or false
if($this->producto->insertarProducto()) {
Flash::addMessage('Prenda ingresada correctamente');
$this->redirect('/inventario/ingreso-correcto');
} else {
Flash::addMessage('Error al ingresar prenda', FLASH::WARNING);
View::renderTemplate('Inventario/nuevo.html',[
'user' => Auth::getUser(),
'producto' => $this->producto,
'controller' => 'inventario'
]);
}
}
</code></pre>
<p>This redirects me to the html I need but without the 'producto' object.</p>
<p>I created the product object in a <code>before</code> method that runs before the other methods are called. </p>
<p>This is what 'redirect' function does (it is on my core/controller class):</p>
<pre><code>public function redirect($url){
header('Location: http://' . $_SERVER['HTTP_HOST'] . $url, true, 303);
exit;
}
</code></pre>
<p>This is the ingreso-correcto HTML:</p>
<pre><code><table>
<tr>
<th>Codigo</th>
<td>{{ producto.codigo }}</td>
</tr>
<tr>
<th>Color</th>
<td>{{ producto.color }}</td>
</tr>
<tr>
<th>Cantidad en stock</th>
<td>{{ producto.cantidad }}</td>
</tr>
<tr>
<th>Descripcion de producto</th>
<td>{{ producto.descripcion }}</td>
</tr>
<tr>
<th>Precio</th>
<td>{{ producto.precio }}</td>
</tr>
<tr>
<th>Costo</th>
<td>{{ producto.costo }}</td>
</tr>
<tr>
<th>Descuento</th>
<td>{{ producto.descuento }}</td>
</tr>
<tr>
<th>Coleccion</th>
<td>{{ producto.coleccion }}</td>
</tr>
<th>Ganancia</th>
<td>{{ producto.ganancia }}</td>
</tr>
</table>
</code></pre>
<p>How can I get the <code>producto</code> object after i've used the <code>redirect</code> method?</p>

Jquery menu active select to Vue JS

How to process a recursive GADT with kind :: '[SomeDataKind]
|
<p>I think this is the furthest into the Haskell type system extensions that I've even been and I've run into an error that I haven't been able to figure out. Apologies in advance for the length, it's the shortest example I could create that still illustrates the issue I'm having. I have a recursive GADT whose kind is a promoted list, something like the following:</p>

-- 'parts' should always contain at least 1 element which is enforced by the GADT.
-- Lets call the first piece of data 'val' and the second 'subdata'.
-- All data constructors have these 2 fields, although some may have
-- additional fields which I've omitted for simplicity.
data SomeData (parts :: [DataKind]) where
MkA :: Maybe Char -> Maybe (SomeData subparts) -> SomeData ('A ': subparts)
MkB :: Maybe Char -> Maybe (SomeData subparts) -> SomeData ('B ': subparts)
MkC :: Maybe Char -> Maybe (SomeData subparts) -> SomeData ('C ': subparts)
deriving instance Show (SomeData parts)
</code></pre>
<p><strong>Problem</strong></p>
<p>What I'm trying to do is traverse the data and perform some operations, for instance propagate the first <code>Just</code> <code>Char</code> found up to the top.</p>
<p><strong>Annoying missing features - needed for the next section</strong></p>
<p>Now, because there is apparently no record syntax support for GADTs (<a href="https://ghc.haskell.org/trac/ghc/ticket/2595" rel="nofollow noreferrer">https://ghc.haskell.org/trac/ghc/ticket/2595</a>) you need to write them manually, so here they are:</p>
<pre><code>getVal :: SomeData parts -> Maybe Char
getVal (MkA val _) = val
getVal (MkB val _) = val
getVal (MkC val _) = val
-- The lack of record syntax for GADTs is annoying.
updateVal :: Maybe Char -> SomeData parts -> SomeData parts
updateVal val (MkA _val sub) = MkA val sub
updateVal val (MkB _val sub) = MkB val sub
updateVal val (MkC _val sub) = MkC val sub
-- really annoying...
getSubData :: SomeData (p ': rest) -> Maybe (SomeData rest)
getSubData (MkA _ sub) = sub
getSubData (MkB _ sub) = sub
getSubData (MkC _ sub) = sub
</code></pre>
<p><strong>Test Data</strong></p>
<p>So, the thing I want to do. Walk down the structure from the top until I find a value that is <code>Just</code>. So given the following initial values:</p>
<pre><code>a :: SomeData '[ 'A ]
a = MkA (Just 'A') Nothing
b :: SomeData '[ 'B ]
b = MkB (Just 'B') Nothing
c :: SomeData '[ 'C ]
c = MkC (Just 'C') Nothing
bc :: SomeData '[ 'B, 'C ]
bc = MkB Nothing (Just c)
abc :: SomeData '[ 'A, 'B, 'C ]
abc = MkA Nothing (Just bc)
</code></pre>
<p><strong>Expected Result</strong></p>
<p>I would like have something like this:</p>
<pre><code>> abc
MkA Nothing (Just (MkB Nothing (Just (MkC (Just 'C') Nothing))))
> propogate abc
MkA (Just 'C') (Just (MkB (Just 'C') (Just (MkC (Just 'C') Nothing))))
</code></pre>
<p><strong>Previous Attempts</strong></p>
<p>I took a few stabs at it, first with a regular function:</p>
<pre><code>propogate sd =
case getVal sd of
Just _val ->
sd
Nothing ->
let
newSubData = fmap propogate (getSubData sd)
newVal = join . fmap getVal $ newSubData
in
updateVal newVal sd
</code></pre>
<p>This gives the error:</p>
<pre><code>Broken.hs:(70,1)-(81,35): error: …
• Occurs check: cannot construct the infinite type: rest ~ p : rest
Expected type: SomeData rest -> SomeData (p : rest)
Actual type: SomeData (p : rest) -> SomeData (p : rest)
• Relevant bindings include
propogate :: SomeData rest -> SomeData (p : rest)
(bound at Broken.hs:70:1)
Compilation failed.
</code></pre>
<p>I also tried a typeclass and attempting to match on the structure:</p>
<pre><code>class Propogate sd where
propogateTypeClass :: sd -> sd
-- Base case: We only have 1 element in the promoted type list.
instance Propogate (SomeData parts) where
propogateTypeClass sd = sd
-- Recursie case: More than 1 element in the promoted type list.
instance Propogate (SomeData (p ': parts)) where
propogateTypeClass sd =
case getVal sd of
Just _val ->
sd
Nothing ->
let
-- newSubData :: Maybe subparts
-- Recurse on the subdata if it exists.
newSubData = fmap propogateTypeClass (getSubData sd)
newVal = join . fmap getVal $ newSubData
in
updateVal newVal sd
</code></pre>
<p>This results in the error:</p>
<pre><code>Broken.hs:125:5-26: error: …
• Overlapping instances for Propogate (SomeData '['A, 'B, 'C])
arising from a use of ‘propogateTypeClass’

instance Propogate (SomeData (p : parts))
-- Defined at Broken.hs:95:10
• In the expression: propogateTypeClass abc
In an equation for ‘x’: x = propogateTypeClass abc
Compilation failed.
</code></pre>
<p>I've also tried combinations of matching on <code>SomeData '[]</code> and <code>SomeData '[p]</code> to no avail.</p>
<p>I'm hoping I'm missing something simple but I haven't found documentation anywhere on how to process a structure like this and I'm at the limits of my understand if the Haskell type system, for now anyways :). Once again, sorry for the long post and any help would be greatly appreciated :)</p>

Closing server using select function
|
<p>So, I am new to socket programming in C and am using the <code>select</code> function to communicate with multiple clients on a server. The server essentially just echos a buffer back to a client based on a requirest. I have used <a href="http://beej.us/guide/bgnet/html/multi/index.html" rel="nofollow noreferrer">Beej's guide to network programming</a> as the model for my server. What is not clear to me is whether I am exiting the server properly when a command is sent to exit. The code for handling the <code>select</code> function looks like:</p>
<pre><code>for (;;)
{
read_fds = master; // Copy the master fds to the basic read...
// Check to see if any flags have been set for reading
if (select(fdmax + 1, &read_fds, NULL, NULL, NULL) == -1)
{
perror("select");
exit(4);
}
for (i = 0; i <= fdmax; i++)
{
if (FD_ISSET(i, &read_fds))
{
if (i == listener)
{ // need to add new connnection here
addrlen = sizeof remote_addr;
newfd = accept(listener, (struct sockaddr *)&remote_addr, &addrlen);
if (newfd == -1)
{
perror("accept");
}
else
{
FD_SET(newfd, &master);
if (newfd > fdmax)
{
fdmax = newfd;
}
}
} // end add new listener
else
{
/*if (i == 0)
{
printf("Input received from stdin\n");
continue;
} */
// handle data from existing client
if ((nbytes = recv(i, input_buffer, sizeof input_buffer, 0)) <= 0)
{ // Remove connection if there is a hangup...
if (nbytes == 0)
{
printf("selectserver: socket%d hung up\n", i);
}
else
{
perror("recv");
}
close(i);
FD_CLR(i, &master);
} // no bytes error or port closed - remove from fdset
else
{
if (strchr(input_buffer,'\r') == NULL){
printf("we have a problem\n");
}
if (strcmp(input_buffer, "exit")){
printf("Exit requested...\n");
close(listener);
exit(0);
}
for (j = 0; j <= fdmax; j++)
{
if (FD_ISSET(j, &master))
{
if (j != listener && j != 0)
{
if (send(j, input_buffer, nbytes, 0) == -1)
{
error_msg = strerror(errno);
printf("%s\n", error_msg);
//perror("send");
}
}
}
}
}
}
}
}
}
</code></pre>
<p>and the code I am specifically concerned about is </p>
<pre><code>if (strcmp(input_buffer, "exit")){
printf("Exit requested...\n");
close(listener);
exit(0);
}
</code></pre>
<p>where <code>listener</code> is the file descriptor for the listening socket. Is this the correct way of exiting this loop or is there a better way to handle this? </p>

Python tkinter passing input value within the same class
|
<p>Most of the code below is just so the problem is accurately replicated, the issue most likely is in the hand-off of <code>filename</code> from<code>askopenfilenameI()</code> to <code>printing(stringToPrint)</code>or the <code>if</code> statement at the end.</p>
<h2>Goal</h2>
<p>The goal of this program is to simply print the file path to the console when <code>Print File Path</code> button is clicked.</p>
<h2>Current state</h2>
<p>When the program is executed the window appears correctly and the it lets you select a file in the file system. Once the file is opened, the script seems to call <code>printing</code> method before it executes its own <code>print</code> statement. When I open another file it prints the only the print statement from <code>askopenfilename()</code> (which is correct).</p>
<p>However, clicking the <code>Print File Path</code> Button does not seem to get work at any stage.</p>
<p>An example output would be:</p>
<p>Value on click: <code>no-file</code></p>
<p>askopenfilename value: <code>C:/Temp/AFTER_FIRST_OPEN.txt</code></p>
<p>askopenfilename value: <code>C:/Temp/AFTER_SECOND_OPEN.txt</code></p>
<h2>Code</h2>
<pre><code>import Tkinter, Tkconstants, tkFileDialog
filename = 'no-file'
class TkApp(Tkinter.Frame):
def __init__(self, root):
Tkinter.Frame.__init__(self, root)
# options for buttons
button_opt = {'fill': Tkconstants.BOTH, 'padx': 5, 'pady': 5}
# define buttons
Tkinter.Button(self, text='Open File', command=self.askopenfilename).pack(**button_opt)
Tkinter.Button(self, text='Print File Path', command=self.printing(filename)).pack(**button_opt)
Tkinter.Button(self, text='Quit', command=self.quit).pack(**button_opt)
# define options for opening or saving a file
self.file_opt = options = {}
options['defaultextension'] = '.twb'
options['filetypes'] = [('All', '*')]
options['initialdir'] = 'C:\\'
options['parent'] = root
options['title'] = 'Select a File'
def askopenfilename(self):
"""Returns an opened file in read mode.
This time the dialog just returns a filename and the file is opened by your own code.
"""
global filename
# get filename
filename = tkFileDialog.askopenfilename(**self.file_opt)
# open file on your own
if filename:
print "askopenfilename value: " + filename
return filename
def printing(self, stringToPrint):

Displaying Div's based on URL using Javascript

<p>I’m new to Javascript and I’m having trouble displaying and hiding some divs based on url’s.</p>
<p>I have 4 divs that need to be shown depending on the url.
The 4 divs are:</p>
<p><strong>Div 1</strong></p>
<pre><code><body onload="callOnPageLoad1()”>
<div id="homeName" style="display:block"><h5>HOME</h5></div>
</code></pre>
<p>and needs to be displayed only when at:</p>
<pre><code>http://www.fitzofdesign.com/
</code></pre>
<p><strong>Div 2</strong></p>
<pre><code><body onload="callOnPageLoad2()”>
<div id="profilesName" style="display:block"><h5>PROFILES</h5></div>
</code></pre>
<p>and needs to be displayed only when at:</p>
<pre><code>http://www.fitzofdesign.com/?category=Profiles

<p><strong>Div 3</strong></p>

</code></pre>
<p>At present the only time this is <strong>working</strong> correctly is when I’m at:</p>
<pre><code>http://www.fitzofdesign.com/
</code></pre>
<p>because Div 1 appears and the other 3 Divs are hidden.</p>
<p>This is <strong>not working</strong> when I’m at: </p>
<pre><code>http://www.fitzofdesign.com/?category=Profiles
http://www.fitzofdesign.com/?category=Retail
http://www.fitzofdesign.com/?category=Blog
</code></pre>
<p>because Div 2, 3 & 4 are all incorrectly displaying for each URL.</p>
<p>I hope this makes sense.</p>
<p>Can anyone help please?</p>
<p>Thanks Rowan</p>

Adding 'mousedown' event listener in a grid which will trigger all cells unless 'mouseup' event occurs
|
<p>I was still working on my Graph Visualizer project and I am unable to figure out how to add <code>mousedown</code> event listener to all the cells. I am trying to draw a wall-like structure. Let me explain when <code>mousedown</code> event occurs that cell will become a wall (I'll add some color) and unless the <code>mouseup</code> event occurs all the cells through where the cursor will pass will also become a wall. I am facing two issues here: I was able to add an event listener to each cell but I am unable to identify which cell was it. Also, I would like to know how to create continuous walls upon <code>mousedown</code>.</p>
<p>Any suggestions or advice is highly appreciated.</p>

keep the new background color of current day in fullcalendar when click on next month or previous month

Missing definitions MVC Views Visual Studio Intellisense

<p>I have a Github project which is an ASP.NET MVC website. There's no trouble in pulling and running the project now. However when coding I get all sorts of errors with e.g:</p>
<pre><code>@ViewBag

<p>Errors:</p>
<blockquote>
<p>The name 'Scrips/ViewBag' does not exist in the current context</p>
<p>'System.Web.WebPages.Html.HtmlHelper' does not contain a definition
for 'LabelFor' and no extension method 'Label'For' accepting a first
argument of type 'System.Web.WebPages.Html.HtmlHelper' could be found

Regular Expression Javascript with XCode
|
<p>i am trying to sieve out the username and text fields of a HTML Form loading in a web view. Previously i tried this method to narrow down the corresponding text fields that i need but it was tedious and there is no end to the computation of variables. even though i thought i listed out a lot of variables, it was still a hit and miss solution, not all website works.</p>
<pre><code>var inputFields = document.querySelectorAll("input[type='text']");
for (var i = inputFields.length >>> 0; i--;) {
if ( (inputFields[i].getAttribute('name') == 'email')
|| (inputFields[i].getAttribute('name') == 'Email')
|| (inputFields[i].getAttribute('name') == 'e-mail')
|| (inputFields[i].getAttribute('name') == 'E-mail')
|| (inputFields[i].getAttribute('name') == 'emailerr')
|| (inputFields[i].getAttribute('name') == 'UID')
|| (inputFields[i].getAttribute('name') == 'uid')
|| (inputFields[i].getAttribute('name') == 'username')
|| (inputFields[i].getAttribute('name') == 'Username')
|| (inputFields[i].getAttribute('name') == 'userName')
|| (inputFields[i].getAttribute('name') == 'user_name')
|| (inputFields[i].getAttribute('name') == 'User_Name')
|| (inputFields[i].getAttribute('name') == 'User_name')
|| (inputFields[i].getAttribute('name') == 'userid')
|| (inputFields[i].getAttribute('name') == 'userID')
|| (inputFields[i].getAttribute('name') == 'UserID')
|| (inputFields[i].getAttribute('name') == 'Userid')
|| (inputFields[i].getAttribute('name') == 'ID')
|| (inputFields[i].getAttribute('name') == 'id')
|| (inputFields[i].getAttribute('name') == 'j_username')
|| (inputFields[i].getAttribute('name') == 'session_key')
|| (inputFields[i].getAttribute('name') == 'login_password')) {
inputFields[i].value = '%@';}}
</code></pre>
<p>Then i was told about RegularExpression but i wasn't very familiar with it and i read some tutorials about it but not specific to my project to try and get what it means and i piece out this code which is also a hit and miss solution. I am not even sure if i am doing it right but the code is definitely short this time for sure. </p>
<pre><code>var inputFields = document.querySelectorAll("input[type='text']");
for (var i = inputFields.length >>> 0; i--;) {
regStr = /(mail|user|iden|name|id|key|login|username|email)/i;
searchName = inputFields[i].getAttribute('name').search(regStr);
searchId = inputFields[i].getAttribute('id').search(regStr);
if (!(searchName == -1) || !(searchId == -1)){
inputFields[i].value = '%@';}}
</code></pre>
<p>Can someone tell me if i have done this RegularExpression correctly? i really have no idea. Some sites it works, some it doesn't. I understand that what i am searching for is configurable by developers and i won't have a 100% hit on all site, but what puzzle me is that sometime even though the term matches exactly one of my search variable it didn't work.</p>

How to make the height of a TextField and a search button equal in Flutter?
|
<p>I'm creating a Flutter app. The app has a <code>TextField</code> and an <code>IconButton</code>, I want to make their height equal. Here is the current code:</p>
<pre class="lang-dart prettyprint-override"><code>import 'package:flutter/material.dart';
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 20),
child: SafeArea(
child: Row(
children: [
const Expanded(
child: TextField(
decoration: InputDecoration(
fillColor: Colors.yellow,
filled: true,
hintText: "Input here...",
isCollapsed: true,
border: OutlineInputBorder(
borderSide: BorderSide(
width: 0,
style: BorderStyle.none,
),
),
),
),
),
const SizedBox(width: 10),
Ink(
decoration: const BoxDecoration(
color: Colors.yellow,
),
child: IconButton(
onPressed: () => {},
icon: const Icon(Icons.search)
),
)
],
)),
),
),
);
}
}
</code></pre>
<p>This is the result:</p>
<p><a href="https://i.stack.imgur.com/93beM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/93beM.png" alt="enter image description here" /></a></p>
<p>You can see that their height is not the same. There are some suggestions on the Internet to make their height equal, but none of them worked for me. Most suggest using a <code>contentPadding</code> inside <code>TextField</code>, like this:</p>
<pre class="lang-dart prettyprint-override"><code>TextField(
decoration: InputDecoration(
fillColor: Colors.yellow,
filled: true,
hintText: "Input here...",
isCollapsed: true,
// Add this
contentPadding: EdgeInsets.all(12),
border: OutlineInputBorder(
borderSide: BorderSide(
width: 0,
style: BorderStyle.none,
),
),
),
),
</code></pre>
<p>This seems to work. My complaint with this method is that I need to manually try the correct padding, which is <code>12</code> in the above code. Does the number always work on all devices? I'm not sure.</p>
<p>Some suggest using a <code>SizedBox</code>, I've tried it, it doesn't work for me either. Here is my code:</p>
<pre class="lang-dart prettyprint-override"><code>import 'package:flutter/material.dart';
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 20),
child: SafeArea(
child: Row(
children: [
const Expanded(
child: SizedBox(
height: 80,
child: TextField(
decoration: InputDecoration(
fillColor: Colors.yellow,
filled: true,
hintText: "Input here...",
border: OutlineInputBorder(
borderSide: BorderSide(
width: 0,
style: BorderStyle.none,
),
),
),
),
),
),
const SizedBox(width: 10),
SizedBox(
height: 80,
child: Ink(
decoration: const BoxDecoration(
color: Colors.yellow,
),
child: IconButton(
onPressed: () => {},
icon: const Icon(Icons.search)),
))
],
)),
),
),
);
}
}

<p><code>{created={type=FREEMIUM, title={value=Drool is love, drool is live..., _iscolumngrouppresent=true}, content={value=null, _iscolumngrouppresent=false}, status=PROCESSING, tags=[], attachments=[{payload_0={video_id=null, image_id=2efbff31-a0a6-4f4c-a163-667c4aabd111}}], visible_at={value=null, _iscolumngrouppresent=false}, author_user_id=8cfdf75d-5816-42f8-906f-8b203bb2c99f, _iscolumngrouppresent=true}, _iscolumngrouppresent=true}</code></p>
<p>Which I would like to convert to</p>
<pre><code> "created": {
"type": "FREEMIUM",
"title": {
"value": "Drool is love, drool is live...",
"_iscolumngrouppresent": True
},
"content": {
"value": None,
"_iscolumngrouppresent": False
},
"status": "PROCESSING",
"tags": [],
"attachments": [
{
"payload_0": {
"video_id": None,
"image_id": "2efbff31-a0a6-4f4c-a163-667c4aabd111"
}
}
],
"visible_at": {
"value": None,
"_iscolumngrouppresent": False
},
"author_user_id": "8cfdf75d-5816-42f8-906f-8b203bb2c99f",
"_iscolumngrouppresent": True
},
"_iscolumngrouppresent": True
}
</code></pre>
<p>I tried to parse the string by myself, but there are cases where it fails. Mainly when a value of a key:value pair is a string with commas in it (",").</p>
<p>Is there a tooling already out there that I can use. Any ideas are more than welcome.</p>
<p>Thanks in advance</p>

Discord.js awaitmessage error, how to fix?
|
<p>I was making this new bot and used awaitmessage function.When a user use the cmd '!gangsug', the bot is supposed to ask a question like - "Please choose a option - RP or Fight" and when the user uses an option it is supposed to give a reply. (Which is a embed one). I have given two different replies for the 2 answers given by the user.(One for the answer "RP" and the other for the answer "Fight"). In this case, by bot is giving same answer for both answer. If the user types "RP" or "Fight" same reply is being given
by the bot. I hope you understood the problem.The code will be given below (ofc only the part where the problem comes)</p>
<pre><code>if (message.content === `${prefix}gangsug`) {
message.reply('Hey there! Please choose a option.\n'
+ 'Confirm with `RP` or with `Fight`.');
// First argument is a filter function - which is made of conditions
// m is a 'Message' object
message.channel.awaitMessages(m => m.author.id == message.author.id,
{max: 1, time: 30000}).then(collected => {
// only accept messages by the user who sent the command
// accept only 1 message, and return the promise after 30000ms = 30s
// first (and, in this case, only) message of the collection
if (collected.first().content.toLowerCase() == 'RP') {
message.reply(suggestgang1);
}
else
message.reply(suggestgang2);
message.reply(suggestgang3);
}).catch(() => {
message.reply('No answer after 30 seconds, req canceled.');
});
} }
);
</code></pre>
<p>**Yea, this is the code..It would be great of you give an answer by stating the problem and a fixed code to replace this one. Thank you :) **</p>

System.IO.FileNotFoundExecption, GUID are different for filename stored in database and file stored on server
|
<p>I am trying to use GUID to allow users to upload files with same names, but the GUIDs attach to filenames & filepaths stored in database are different from the GUIDs attached to the files stored on server. It means it is giving two different GUIDs to the same file. So when I am trying to download the file from server its giving me an FileNotFound exception as the command arguement takes the filename from database and therefore when it goes to server its not able to find the file as the GUID of the same file stored on the server is different.
Please if anybody can give me some advise that would be appreciable.</p>
<p>My Database schema:</p>
<pre><code>Table: Sales
Columns: ReceiptFileName(Stores Name without GUID)
Coulmn:ReceiptFilePath(Stores file path with GUID)
Column: filename(Stores filename with GUID)
</code></pre>
<p>Aspx code:</p>
<pre><code><ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Download" CommandArgument='<%# Bind("filename") %>' Text='<%# Bind("ReceiptFileName") %>' ></asp:LinkButton>
</ItemTemplate>
</code></pre>
<p>Code for upload:</p>
<pre><code>if (FileUpload1.HasFile)
{
//check file Extension & Size
string filename = FileUpload1.PostedFile.FileName;
{
filename = filename + Guid.NewGuid();
}
int filesize = FileUpload1.PostedFile.ContentLength;
if (filesize > (20 * 1024))
{
Label1.Text = "Please upload a zip or a pdf file";
}
string fileextention = System.IO.Path.GetExtension(FileUpload1.FileName);
if (fileextention.ToLower() != ".zip" && fileextention.ToLower() != ".pdf")
{
Label1.ForeColor = System.Drawing.Color.Green;
Label1.Text = "Please upload a zip or a pdf file";
}
else
{
//string ReceiptFileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
string ReceiptFileName = Path.GetFileName(filename);
//save file to disk
FileUpload1.SaveAs(Server.MapPath("~/Reimbursement/Reciepts/" + ReceiptFileName));
}
}
</code></pre>
<p>Method for adding filename and receiptname</p>
<pre><code>public static int AddSale(SaleID, string ReceiptFileName,string ReceiptFilePath, string filename)
{
int sale;
SqlCommand addSales = new SqlCommand("addSale", con);
addSale.CommandType = CommandType.StoredProcedure;
addSale.Parameters.AddWithValue("@ReceiptFileName", ReceiptFileName);
addSale.Parameters.AddWithValue("@filename", filename);
addSale.Parameters.AddWithValue("@ReceiptFilePath", ReceiptFilePath);
try
{
con.Open();
added = addSale.ExecuteNonQuery();
}
finally
{
con.Close();
}
</code></pre>
<p>Code for download:</p>
<pre><code>protected void gridExpenditures_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Download")
{
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AppendHeader("content-disposition", "FileName=" + e.CommandArgument);

<p>When i delete the switch condition part, and put this code, i don't get any exception :</p>

<p>.I tryed to run the code mannualy ,and i did not found an error (maybe i don't see it ).
Here the running stops (Log.i )</p>
