Loading multiple images on a page for Blackberry 10
|
<p>I am working on BB10 cascades. I am trying to load multiple images from network. I have referred <a href="http://blackberry.github.io/Cascades-Samples/imageloader.html" rel="nofollow">following example</a> and I have modified it to load a single image. Sample code is as follows:</p>
<p><strong>main.qml</strong></p>
<pre><code>import bb.cascades 1.2
Page {
Container {
id: outer
Container {
preferredHeight: 500
preferredWidth: 768
layout: DockLayout {}
onCreationCompleted: {}
// The ActivityIndicator that is only active and visible while the image is loading
ActivityIndicator {
id: activity
horizontalAlignment: HorizontalAlignment.Center
verticalAlignment: VerticalAlignment.Center
preferredHeight: 300
visible: _loader.loading
running: _loader.loading
}
// The ImageView that shows the loaded image after loading has finished without error
ImageView {
id: image
horizontalAlignment: HorizontalAlignment.Fill
verticalAlignment: VerticalAlignment.Fill
image: _loader.image
visible: !_loader.loading && _loader.label == ""
}
// The Label that shows a possible error message after loading has finished
Label {
id: lable
horizontalAlignment: HorizontalAlignment.Center
verticalAlignment: VerticalAlignment.Center
preferredWidth: 500
visible: !_loader.loading && !_loader.label == ""
text: _loader.label
multiline: true
}
}
Button {
text: "load Image"
onClicked: {
_loader.load();
console.log("loading:::"+_loader.loading);
}
}
}
}</code></pre>

<p>Now I want to load multiple images. I tried to create <code>QList<QObject*>* image;</code>
and add instances of the <code>ImageLoader</code> class, but I don't know how to access it in main.qml.
Any ideas how to do so?</p>

Are Blank Tag Names Causing A Parsing Error?
|
<p>I'm trying to restructure some XML by taking the data, creating a DOM doc, and transferring across just the bits I need, before saving the output, however I keep getting a "XML Parsing Error: no element found: Line Number 1, Column 1:" error. I think it's related to the blank tags inside the first :</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<report title="My Programs" name="aAffiliateMyProgramsReport" time="2012-11-27 16:06">

</row>........
</code></pre>
<p>And here's the PHP I'm trying to run:</p>
<pre><code>//contents of MyPrograms report - tested $query in browser many times: it is correct
$query = $q1.$siteID.$q2.$rKey.$q3;
//create DOM document for newTree
$newTree = new DOMDocument();
$newTree->formatOutput =true;
$r = $newTree->createElement ("ProgramTariffs");
$newTree->appendChild($r);
//load contents of MyPrograms report into an xml element
//$oldTree = simplexml_load_file($query);
//that wasn't working so tried file_get_contents instead
$oldTree = file_get_contents($query);
//the above is now at least allowing this script to produce an xml file, but it just contains
"<?xml version="1.0"?> <ProgramTariffs/>"
//and still throws the no element found error.................................
//for each instance of a program id in $oldTree.....
foreach($oldTree->matrix->rows->row as $program)
{ //an attempt to skip over first $program if nothing is set
if (!empty($program->programId)) {
//create the top line container tag
$row = $newTree->createElement ("programTariff");
//create the container tag for programId
$progID = $newTree->createElement("programId");
//fill it with the information you want
$progID->appendChild ( $newTree->createTextNode ( $program->programId ) );
//attach this information to the row
$row->appendChild($progID);
//create the container tag for eventName
$eventName = $newTree->createElement("eventName");
//fill it with the information you want
$eventName->appendChild ( $newTree->createTextNode ( $program->event ) );
//attach this information to the row
$row->appendChild($eventName);
//create the container tag for eventAmount
$eventPercent = $newTree->createElement("eventPercent");
//fill it with the information you want
$eventPercent->appendChild ( $newTree->createTextNode ( $program->programTariffPercentage ) );
//attach this information to the row
$row->appendChild($eventPercent);
//attach all of the above to a row in NewTree
$r->appendChild ($row);
}
}
//save the output
$newTree->save("ProgramTariffs.xml");
</code></pre>
<p>Have I made a basic mistake in accessing the original XML, or do I need to find a better way to work around the row containing a tag name of "<>" ?</p>
<p>I await your wrath / salvation</p>

Can we freeze columns in HTML on basis of colgroup?
|
<p>I was dealing with complex tabular data and wanted to freeze the header and column heading but on the "col" tag.
I can freeze the row heading with position sticky for each tag but then for the second heading when I use-value of the width in the left position the table distorts in some large screens.</p>
<pre><code>th{
position:sticky;
}
tr:nth-child(1){
left:0;
}
tr:nth-child(1){
left:5%;
}
</code></pre>
<p>this doesn't works on large screens.</p>
<p>Sample data:</p>
<pre><code><table border = 1>
<colgroup>
<col style="widht:5%;" width="5%"/>
<col style="widht:5%;" width="5%"/>
<col style="widht:5%;" width="5%"/>
<col style="widht:5%;" width="5%"/>

getting an attribute from a tag with beautiful soup

<p>I am trying to get the attribute 'datetime' but cant seem to do it right for the past couple of hours:</p>
<pre><code> driver.get("https://cointelegraph.com/tags/bitcoin")

soup = BeautifulSoup(page_source, 'html.parser')

for article in articles:
print("--------------------------------")
if article.has_attr('datetime'):
print(article['datetime'])
else:
print('no attribute present')
</code></pre>
<p>I execute this and its seems that said attribute is not there:</p>
<pre><code>--------------------------------
no attribute present
--------------------------------
no attribute present
--------------------------------
no attribute present
--------------------------------
no attribute present

<p>I checked the HTML and the 'datetime' attribute is there within the 'article' tag. But it looks like it only has one attribute which is 'class'.</p>

Weird behavior of Redux thunk in a React Native app
|
<p>I recently noticed a very weird behavior of Redux in my app that I would like to share with you. When I click this TouchableOpacity in my settings in order to disconnect, I get the following error: </p>
<blockquote>
<p>TypeError: Cannot read property first_name of null</p>
</blockquote>
<p>from Homepage.js</p>
<p>So my code is firing an error for that piece component that is in a page where I'm not supposed to go.</p>
<p><strong>Homepage.js</strong></p>
<pre><code><AppText textStyle={styles.title}>
Welcome {userReducer.infos.first_name}
</AppText>
</code></pre>
<p>The workflow that is supposed to happen is the user clicking on the disconnect button, then the tryLogout function is called, which fires the action with the type 'LOGOUT'. Then this action sets to null user related data and information with some additional booleans. The state gets updated then the UI should be re-rendered and componentWillUpdate() called. In there, I check my state to redirect the user to the landing/not connected navigation.</p>
<p>I tried to comment <code>infos: null</code> in my reducer and my code processes without errors.</p>
<p>This variable is nowhere in my app asking to redirect to any page.</p>
<p>It may seem complicated to debug, since the problem must be deeper than it looks. Anyway, maybe someone has already had a similar problem so I give you here the potential elements to try to solve the problem.</p>
<p><strong>Settings.js</strong></p>
<pre><code>import { tryLogout } from '@actions/user'
const mapDispatchToProps = dispatch => ({
tryLogout: () => dispatch(tryLogout()),
})
class Settings extends React.Component<Props, State> {
// What should normally happen
componentDidUpdate(prevProps: Props) {
const { userReducer, navigation } = this.props
if (
prevProps.userReducer.isSignedUp !== userReducer.isSignedUp ||
prevProps.userReducer.isLoggedIn !== userReducer.isLoggedIn
) {
if (!userReducer.isSignedUp && !userReducer.isLoggedIn) {
navigation.navigate('Landing')
}
}
}
// Inside my render() method
<AppTouchableOpacity
onPress={() => tryLogout()}
style={styles.touchableOpacity}
>
Disconnect
</AppTouchableOpacity>
}
</code></pre>

PHP Javascript - cannot change selector onclick to Remove preview files
|
<p>I'm doing upload multiple files(use <code><input type="file" multiple/></code>) with preview image file and can remove the image preview and filedata successfully.</p>
<p>but the problem is, I cannot change the selector for onclick to remove filedata.
(If I change to other selector, it will only remove the preview image but the files still be uploaded to my folder)</p>
<p>The selector for click to remove that work successfully is <code>.selFile</code> but when
I want to change selector for onclick to <code>.selFile2</code> it will not remove filedata) </p>
<p>these are my focus line of code. (To see my Full code, Please look on bottom) </p>
<pre><code> var html = "<div><img src=\"" + e.target.result + "\" data-file='"+f.name+"' class='selFile'
title='Click to remove'> <span class='selFile2'>" + f.name + "</span><br clear=\"left\"/></div>";
</code></pre>
<p>..</p>
<p>I change from </p>
<pre><code>$("body").on("click", ".selFile", removeFile);
</code></pre>
<p>to</p>
<pre><code>$("body").on("click", ".selFile2", removeFile);
</code></pre>
<p>but it remove preview image only not remove filedata (it's still be uploaded to my folder)
..</p>
<p>And I try to change code in <code>function removeFile(e)</code>
from <code>var file = $(this).data("file");</code> to <code>var file = $('.selFile).data("file");</code> the result is It can remove only 1 filedata.

PHP form required fields error message not shown
|
<p>Why there's no error message shown in the browser window?
(had more fields but reduced all to a minimum)
There is just nothing happening but that it is redirecting to the 'save_entries.php'.
I would have liked the error message in the table as first row, second column.</p>
<p>The code:</p>
<pre><code><?php
session_start();
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$errors = array();
if (empty($_POST['name']))
{
$errors['name'] = "Please insert your name!";
}
if (count($errors) == 0)
{
header("Location: save_entries.php");
exit();
}

<p>I can't figure out where am I going wrong. Any help would be much appreciated.
It takes the inputs but after that it says segmentation error. Split the given single linked list into two where I can store the odd vales and even values separately .I tried different methods but couldn't get it to work.</p>

Chart.js Show label/tooltip for single point when multiple points coincide
|
<p>I have a Chart.js scatter plot where data points from two different datasets occasionally coincide/overlap. They have the same x and y coordinate. On default, when the points are hovered, the tooltip shows info for both data points. My desired behavior is to get the information for the first overlapping point only. I can achieve this using tooltips' mode set to 'single'.</p>
<pre><code>var config = {
options: {
tooltips: {
mode: "single"
}
}
}
</code></pre>
<p>Although this works fine, my question/problem arises because chart.js' documentation states that mode 'single' is <a href="https://www.chartjs.org/docs/latest/general/interactions/modes.html#single-deprecated" rel="nofollow noreferrer">deprecated</a>. It suggests using mode 'nearest' with intersect set to 'true' would achieve the same result, however <a href="https://jsfiddle.net/f5epdn2w/" rel="nofollow noreferrer">it doesn't</a>.</p>

is there a javascript method for telling us if a input range slider value is going up vs down?
|
<p>I'm trying to group input range sliders or 'faders' together so that one 'Group Fader' can control two or more faders while keeping their respective relative values intact.
So if fader One has a value of '50' and fader Two has a value of '75' When we group them together and increase the Group Fader by +20, faders one and two will move simultaneously and have their new new respective values 70 and 95.</p>

Attempts to access this ref will fail. Did you mean to use React.forwardRef()?
|
<p>I'm trying to create a sign up form with an input for a users address. The address input uses the google autocomplete address api.</p>
<p>I'd like to be able to keep it as a <code>Formik</code> field, so I can use <code>Yup</code> validation on it.</p>
<p>The address input component looks like</p>
<pre><code>// Google.jsx
import React from "react";
import { Formik, Form, Field, ErrorMessage } from "formik";
/* global google */
class SearchBar extends React.Component {
constructor(props) {
super(props);
this.autocompleteInput = React.createRef();
this.autocomplete = null;
this.handlePlaceChanged = this.handlePlaceChanged.bind(this);
}
componentDidMount() {
this.autocomplete = new google.maps.places.Autocomplete(this.autocompleteInput.current,
{"types": ["address"]});
this.autocomplete.addListener('place_changed', this.handlePlaceChanged);
}
handlePlaceChanged(){
const place = this.autocomplete.getPlace();
console.log(place);
}
render() {
return (
<Field ref={this.autocompleteInput} id="autocomplete" type="text" name="address" placeholder="" />
);
}
}
export default SearchBar;
</code></pre>
<p>And my <code>Form</code> component looks like:</p>
<pre><code>import React from "react";
import { Formik, Form, Field, ErrorMessage } from "formik";
import * as Yup from "yup";
import SearchBar from "./Google";
const LoginSchema = Yup.object().shape({
fName: Yup.string().required("Please enter your first name"),
address: Yup.string().required("invalid address"),
});
class Basic extends React.Component {
render() {
return (
<div className="container">
<div className="row">
<div className="col-lg-12">
<Formik
initialValues={{
fName: "",

}}
validationSchema={LoginSchema}
onSubmit={(values) => {
console.log(values);

}}
>
{({ touched, errors, isSubmitting, values }) =>

</div>
</div>
)
}
</Formik>
</div>
</div>
</div>
);
}
}
export default Basic;
</code></pre>
<p>This returns an error of "Function components cannot be given refs. Attempts to access this ref will fail. Did you mean to use React.forwardRef()?".</p>
<p>Which is coming from my address input component at:</p>
<pre><code><Field ref={this.autocompleteInput} id="autocomplete" type="text" name="address" placeholder="" />
</code></pre>
<p>Everything else is working, I just need to get past this last hurdle and I'll be good from here.</p>
<p>I will begin looking into the docs, but I'm unfortunately in a rush to get this done so I figured I'd try my luck here!</p>
<p>Any help is greatly appreciated! Thank you!</p>

How to generate object ids when $unwinding with aggregate in mongodb
|
<p>I'm having the following query</p>
<pre><code>db.getCollection('matches').aggregate([{
"$lookup": {
"from": "player",
"localField": "players.account_id",
"foreignField": "account_id",
"as": "players2"
}
}, {
"$addFields": {
"players": {
"$map": {
"input": "$players",
"in": {
"$mergeObjects": [
"$$this", {
"$arrayElemAt": [
"$players2", {
"$indexOfArray": [
"$players.account_id",
"$$this.account_id"
]
}
]
}
]
}
}
}
}
}, {
"$set": {
"players.match_id": "$match_id",
"players.radiant_win": "$radiant_win"
}
}, {
"$unwind": "$players"
}, {
"$replaceRoot": {
"newRoot": "$players"
}
}, {
"$project": {
"_id": 1,
"match_id": 1,
"account_id": 1,
"hero_id": 1,
"radiant_win": 1
}
}
])
</code></pre>
<p>which is supposed to match an inner array with another collection, merge the objects in the arrays by the matching and then unwrap ($unwind) the array into a new collection.</p>
<p>Unfortunately, I'm getting duplicate Object ids which is sort of a problem for when I want to export this collection.</p>
<p>How can I ensure unique Object_Ids for the aggregation?</p>
<p>Thanks in advance!</p>

Inconsistent Imports in React (create-react-app)
|
<p>returning to React for the first time in a while and having some strange issues I'm having trouble resolving. It seems like my imports are behaving inconsistently and I'm not sure why that might be. Here's the file in question:</p>
<pre><code>import React from 'react';
import axios from 'axios';
import {VanillaPuddingApi} from '../components/constants';
class Clients extends React.Component {
constructor(props){
super(props)
this.state={
clients: []
}
}
componentDidMount(){
debugger;
alert(VanillaPuddingApi)
axios
.get(`${VanillaPuddingApi}/clients`)
.then(({data}) => {
debugger;
})
.catch((errors)=>{
console.log(errors)
})
}
render() {
return (
<div>
{VanillaPuddingApi}
</div>
);
}
}
export default Clients;
</code></pre>
<p>This file is rendered properly on the page by the <code>App.js</code> file from the default create-react-app directory. Additionally, the value of <code>VanillaPuddingApi</code> is properly rendered on the DOM. The first debugger in the <code>componentDidMount()</code> call is problematic- if I check the value of <code>VanillaPuddingApi</code> in the console on that line, I get the following error message:</p>
<pre><code>`Uncaught ReferenceError: VanillaPuddingApi is not defined
at eval (eval at componentDidMount (Clients.js:15), <anonymous>:1:1)

</code></pre>
<p>Yet, on the very next line, this value is alerted out as expected. The real issue here is that Axios isn't working. When trying to run the <code>axios.get</code> line manually in the debugger, I get the same error as above. I did some digging and found people with similar issues who had issues with their webpack.config.js files, but mine looks unlike theirs did and this doesn't seem to explain my local importing issue.</p>
<pre><code>//webpack.config.js
module.exports = {
module: {
rules: [
{
test: /\.pug$/,
use: [
"pug-loader?self",
]
},
{
test: /\.css$/,
use: [
"style-loader",
"css-loader"
],
}
]
}
};
</code></pre>
<p>and also my package.json file:</p>
<pre><code>//package.json
{
"name": "vanilla-pudding-frontend",
"version": "0.1.0",
"private": true,
"dependencies": {
"axios": "^0.16.2",
"react": "^15.6.1",
"react-dom": "^15.6.1",
"react-router-dom": "^4.2.2"
},
"devDependencies": {

},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
</code></pre>
<p>and finally </p>
<pre><code>// components.constants
export const VanillaPuddingApi = "http://localhost:5000/"
</code></pre>
<p>Any help much appreciated, thank you.</p>

Android Custom XML layout for SQLite
|
<p>So I have been working on a project app that reads from a database and prints the contents of the DB into a list view. I now want to print more then just one column, I want to add two buttons and an edittext to the row that is being printed. I have created the new xml file that I want to use but when i try to set the new layout to be this xml file it doesnt work. Can anyone explain or show me how to fix my problem?</p>
<p>This is the XML layout I want to use for each row
</p>
<pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView android:id="@+id/item1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30sp"
android:paddingBottom="5dp"
android:hint="@string/hint"/>
<Button
android:id="@+id/plusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/plusButton"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText
android:id="@+id/edit1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="@string/hint"
android:layout_alignParentTop="true"
android:layout_toLeftOf="@+id/minusButton"

ContextMenu in a ListView/GridView
|
<p>Inside a ListView, I have a GridView and am trying to set things up so that when the user right clicks a 'row' in the ListView, I'm able to access the original data object.
I think its the gridview part of the ListView that is making this a bit more difficult.</p>
<p>I've created a sample that demonstrates where I'm having difficulties. When the user right clicks the row eg Person1, I'd like to able to access the PersonClass data object in the MenuItem_Click handler.

<p>I am not using the byfn.sh to start the network, but manually with:</p>
<p>docker-compose -f docker-compose-cli.yaml up -d</p>
<p>I have not loaded any sample chaincode. I have joined the orderer and three peers to the channel in the CLI.</p>
<p>Is there something i am missing with the certificate authority when starting the network?</p>
<p>Bit stuck at getting this going so any help would be very much appreciated.</p>

Include pymssql in py2app

Zurb Foundation top-bar not working on small screens
|
<p>I just started using foundations and frankly, its been a while since i built my last website. so please be pacient with me.</p>
<p>I deal with an issue with my menu (top-bar) now for over a day and can not find a clue what is going wrong.</p>
<p>The thing is, I really just need a basic menu, which is toggeling to the standard burger-menu on small screens, so far so good, it should work like demonstrated in the documentation right? But unfortunatly it does not and I cant figure out why.</p>
<p>I hope you can help me. I add my code without contents below. The file lies in a subdirectory, thats why all directory references are with ../ at the beginning.</p>
<p>Thanks a lot already!
Ina</p>

Is it possible to make an image move with the cursor when it gets near, and have collision?
|
<p>I am creating a maze game. I got provided with how I would make an image not able to enter a div with jQuery. I also have a code with the image following the cursor. In the second code, I made it so that the image would only go to the mouse if it was a certain distance away. With the collision, the code from the second code got messed up, and now the image teleports to the cursor, instead of how I want it to act. How can I fix this? I am flexible if you need to use pure js or jquery UI. I highly prefer jQuery.</p>
<h1>jQuery from first code:</h1>
<pre><code>function collisionCheck(ax,ay) {
var collide = false;
var aminY = ay;
var aminX = ax;
var amaxX = aminX + $('#image').width();
var amaxY = aminY + $('#image').height();
$('.maze').each(function(){
collide = false;
var bminY = $(this).offset().top - $(window).scrollTop();
var bminX = $(this).offset().left - $(window).scrollLeft();
var bmaxX = bminX + $(this).width();
var bmaxY = bminY + $(this).height();
if (amaxX < bminX) collide = true; // a is left of b
if (aminX > bmaxX) collide = true; // a is right of b
if (amaxY < bminY) collide = true; // a is above b
if (aminY > bmaxY) collide = true; // a is below b
if (!collide) {
return collide;
}
});
return collide;
}
$(document).ready(function(){
$(document).mousemove(function(e) {
startMove = true;
var cursorY = e.pageY;
var cursorX = e.pageX;
if (collisionCheck(cursorX, cursorY)) {
$('html').removeClass('showCursor');
$("#image").css({
left: e.pageX,
top: e.pageY
});
} else {

HTML + Hiding element from table based on value from another column
|
<p>I am trying to hide a button in a table column based on another column value, there's a table column field call "Archive" and if that value is true, I want to hide a button from another column. The code below I have however only hides the button in the first row and ignore subsequent rows. Please kindly assist. Thanks.</p>
<pre><code><table class="table table-striped table-bordered">
<tr>
<td width="8%" class="table_pink" style="background-color:#ED4085">Name</td>
<td width="8%" class="table_pink" style="background-color:#ED4085">Email</td>
<td width="8%" class="table_pink" style="background-color:#ED4085">Country</td>

What is a SMART WAY to deal with a lot of repeated If statements checks?
|
<p>In my attempt to create a searching tool for a database that I created in the context of my undergrad thesis, I am required to make a lot of checks on the values that the user has entered, and according to those values, generate and execute the appropriate <code>MySQL query</code>. An example follows:</p>
<p><code>HTML Code</code></p>
<pre><code>(part of the whole table)
<tr id="tablerow" class="">
<th id="selectth">
<select class="selection" name="Attributes" id="Attributes">
<!-- List of all the available attributes for the user to select for the searching queries -->
<option disabled>Options</option>
<option value="Name" id="p_Name">Name</option>
<option value="ID" id="p_Id">Patient ID</option>
<option value="Sex" id="p_Sex">Sex</option>
<option value="Email" id="p_Email">Patient Email</option>
<option value="Age" id="p_Age">Age ></option>
<option value="Agesmaller">Age < </option>
<option value="Race" id="p_Race">Race</option>
<option value="PhoneNumber" id="p_Phonenum">Phone Number</option>
<option value="Comorbidities" id="p_Comorbidities">Comorbidities</option>
<option value="EDSS" id="p_eddsscore">EDSS Score</option>
<option value="Pregnant" id="p_Pregnant">Is Pregnant</option>
<option value="Onsetlocalisation" id="p_Onsetlocalisation">Onset Localisation</option>
<option value="Smoker" id="p_Smoker">Is a Smoker</option>
<option value="onsetsymptoms" id="p_onsetsymptoms">Onset Symptoms</option>
<option value="MRIenhancing" id="p_MRIenhancing">MRI Enhancing Lesions</option>
<option value="MRInum" id="p_MRInum">MRI Lesion No.</option>
<option value="MRIonsetlocalisation" id="p_MRIonsetlocalisation">MRI Onset Localisation</option>
</select>
</th>
</code></pre>
<p>and as another part of that same table, I have a button that allows the user to create a second row of input in order to make a more specific search, with 2 attributes, either with AND or with an OR statement.
<code><button type="button" id="new_row_btn" onclick="addRow()" name="new_row">Add an extra row</button></code></p>
<p>I would like to keep this post sort in order to receive an answer, so I won't include the addRow() JavaScript function, <strong>but if it is necessary</strong> please comment it and I will edit this ASAP.</p>
<p>My question is the following, I have those 2 inputs, and I want to check if the user has entered anything on the second row of inputs (in the "advanced" one) and then based on the new value execute the appropriate query.</p>
<p>The PHP code as of now looks something like this:</p>
<p><code>PHP Code</code></p>
<pre><code>if($option == 'Name' && $newoption == 'Email' && !empty($newEmail)){
$sql = "SELECT patients.Patient_id,patients.Patient_name,patients.DOB,patients.Phonenum,patients.Email,MSR.Sex FROM patients,MSR WHERE patients.Patient_id = MSR.NDSnum AND Doctor_ID = $usersid AND patients.Email = '$newEmail' $and_or patients.Patient_name LIKE '%$entry%' ORDER BY Patient_id";
$result = $pdo->query($sql);
if ($result->rowCount() > 0) {
while ($row = $result->fetch()) { ?>
<table id="standard">
<tr>
<th>Patient ID</th>
<th>Name</th>
<th>Date of Birth</th>
<th>Phone Number</th>
<th>Email</th>
<th>Sex</th>
<th>Previous Visits</th>
</tr>
<tr>
<td><?php echo $row['Patient_id']; ?></td>
<td> <?php echo $row['Patient_name']; ?> </td>
<td><?php echo $row['DOB']; ?></td>
<td><?php echo $row['Phonenum']; ?></td>
<td><?php echo $row['Email']; ?></td>
<td><?php echo $row['Sex']; ?></td>
<td><?php echo "<a href='/application/previousvisit-bootstrap.php?id=" . $row['Patient_id'] . "'>Previous Visits</a>"; ?></td>
</tr>
</table>
<div class="line"></div>
<?php }
} else {
echo "No patient exists with this information. Name+Email";
}
} if ($option == 'Name' && $newoption == 'Age' && !empty($newAge)){
$sql = "SELECT * FROM patients WHERE timestampdiff(year,dob,curdate()) > '$entry' $and_or patients.Patient_name LIKE '%$entry%' AND Doctor_ID = $usersid ORDER BY Patient_id";
$result = $pdo->query($sql);
if ($result->rowCount() > 0) {
while ($row = $result->fetch()) { ?>
<table id="standard">
<tr>
<th>Patient Id</th>
<th>Patient Name</th>
<th>Date of Birth</th>
<th>Phone Number</th>
<th>Email</th>
<th>Previous Visits</th>
</tr>
<tr>
<td><?php echo $row['Patient_id']; ?></td>
<td> <?php echo $row['Patient_name']; ?> </td>
<td><?php echo $row['DOB'] ?></td>
<td><?php echo $row['Phonenum']; ?></td>
<td><?php echo $row['Email']; ?></td>
<td><?php echo "<a href='/application/previousvisit-bootstrap.php?id=" . $row['Patient_id'] . "'>Previous Visits</a>"; ?></td>
</tr>
</table>
<div class="line"></div>
<?php }
} else {
echo "No patient exists with this information. Name+Age";
}
</code></pre>
<p>The above if statement goes on for about 20 more times... each time checks one attribute in relation to another.. for example
<code>Name+newID</code> or <code>ID+newName</code> or <code>Email+newSex</code>
Obviously I know that Im not done and that there are hundreds of possible combinations with those attributes, but I was wondering if there is some way to avoid all this and make it kinda easier....</p>
<p><strong>Im sorry for the long question!</strong> Any notes on how to make this a better question are welcome.</p>
<p>Thank you in advanced for you time.</p>

<p>I have looked further for trying to resolve the above error. adding <code>proxy_ssl_server_name on</code> did nothing. I have looked at another solution but weren't really helpful in resolving the issue I had.</p>

Remove duplicate form select result

<h1>#edited</h1>
<p>Ok. I will delete all role permissions and add them again.</p>
<p>Is it possible to combine all 4 queries into one?</p>
<hr>
<p>I am creating a permission system.</p>
<p>Assumptions:</p>
<ul>
<li><p>Each user can have more than one role</p></li>
<li><p>Each role can have more than one permission</p></li>
<li><p>Permissions can also be assigned directly to the user (they have a higher priority than permissions for roles)</p></li>
</ul>
<p>The priority of permissions is:</p>
<ul>
<li><p>role permission</p></li>
<li><p>denial of role</p></li>
<li><p>user permission</p></li>
<li><p>denied to user</p></li>
</ul>
<p>Denying the user has the highest priority</p>
<hr>
<p>The matter in PHP is quite simple:</p>
<ul>
<li><p>I create an array with all permissions</p></li>
<li><p>I am getting permissions for a role (order by access)</p></li>
<li><p>I assign access, if it's denied, I overwrite access with denied</p></li>
<li><p>I do the same for user permissions</p></li>
<li><p>I assign access, if it's denied, I overwrite access with denied</p></li>
</ul>
<p>This way I have the whole array with permissions for a specific user, e.g. $ user['permission']['delete_post'] // output: false || true</p>
<p>I need to do permission inspection now. This means which user has access to e.g. 'delete_post'</p>
<p>I have this database scructure:

<p>I have problem with first query:</p>

| ------- | ------ | ------------- |
| 5 | 0 | 3 |
| 8 | 1 | 3 |
| 10 | 1 | 3 |
| 10 | 0 | 3 |
</code></pre>
<p>As expected I should get </p>
<pre><code>| role_id | access | permission_id |
| ------- | ------ | ------------- |
| 8 | 1 | 3 |
</code></pre>
<p>I cant add <code>WHERE permission_id=3 AND access=1</code>, because i getting result: role_id=8 and role_id=10, but role_id=10 doesn't really have access.</p>

combining get_absolute_url into a raw SQL statement in django
|
<p>Am working on a django application with uses several complex queries to return ranks, ratios and other complicated output. I've followed few exampled from the web which helped me find the best way to put it and retrieve data from the query set returned</p>
<p>Yet, I would like to find a way to inject custom details into a given record, for example in my case, am trying to associate the get_absolute_url() value into the returned record set</p>
<p>Below is an example which returns the most used interests, this query will always return a limited queryset, is there a way to extend the returned dictionary with the get_absolute_url() value of the model? </p>
<pre><code>def most_used_interests(self, limit_by=10):
cursor = connection.cursor()
cursor.execute("""
SELECT
i.name,
i.name_ar,
i.name_en,
ij.interest_id,

PHP emails from form scramble cyrillic characters
|
<p>Here's what this is all about. Since I am using PHP as of today I am facing this issue.
I have build a form , for the ISP company that I work for, which emails the form results. Customers fill out this form to request new service from us. Since the company is foreign (Bulgarian) 99% of people are going to fill it out in Cyrillic , so I tested it by filling it out myself and I got this email.</p>
<hr>
<p>From: ÐÑд </p>
<p>Phone number: 56 </p>
<p>Selected Services: </p>
<p>Internet: 100 || TV: comfort </p>
<p>Message: </p>
<p>ЪЕÐÐÐÐÐÐ </p>
<hr>
<p>So I made some research , checked out a few other posts about this in StackOverflow but none worked... most suggested to add
<code>$header .= "\nContent-type: text/plain; charset=\"utf-8\"";</code></p>
<p>One issue is that I'm not sure EXACTLY how to implement this solution, second is that it didn't work for the person who asked the question, not even in one of the questions I reviewed.</p>
<p>Here is the PHP code and the HTML one, hoping you can give me an EXACT way of fixing it, since I have barely no idea of syntax in PHP.</p>

</code></pre>
<p>Another interesting fact is that when I opened the file from my local machine (since if I try from the one hosted online, I will get the error echo) the Cyrillic text in the php code itself was displayed just like the email result...
But when I opened it from the host , by directly addressing it I got the error message right... in Bulgarian... without any gibberish.</p>
<p>The line of code in the PHP</p>
<pre><code>header('Content-Type: text/html; charset=utf-8');
</code></pre>
<p>seemed to convert the header message. I tried addressing <code>$name_field('Content-Type: text/html; charset=utf-8');</code></p>
<p>But result was <em>blank</em>, the php didn't function properly, I'm guessing since I gave it a wrong or inoperable line of code with that addressing of <code>$name_field</code>.</p>
<p>Question is, how do I address it properly and I'm I even on the right track with this approach?</p>

Google Map API not plotting array of markers
|
<p>I need some advice or a telling off because my code is wrong. I'm new to JQuery and google maps api. I have a JSON get to retrieve my data. I have declared an array and stored (hopefully this is the correct way to do this).</p>
<p>update** - Thanks to @geocodezip I have updated my code to allow correct population of array.</p>
<p>When I run my application the map loads fine but no markers.
I have changed my Google maps initializeMap() to the asynchronous version </p>
<pre><code>function initializeMap() {
var map = new google.maps.Map(document.getElementById("googleMap"), {
zoom: 12,
center: new google.maps.LatLng(citylat, citylng),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < carparksArray.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(carparksArray[i][1], carparksArray[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(carparksArray[i][0]);
infowindow.open(map, marker);
}

QUEUE and 'IF' 'ELSE' 'WHILE' statements from scratch and running functions
|
<p>I'm making a game engine in javascript, and needed some way to code some actions.</p>
<p>The code is here:</p>
<pre><code><!DOCTYPE html> <html> <body> <script>
var engine={}, actions={}; engine.atomStack=new Array();
events = {
1: ["action1|5","action2|2;2","action1|2"],
2: ["action2|5;2","action2|2;2"],
3: ["action2|5;2","action1|2"] };
engine.runatomStack = function(){
while(engine.atomStack.length > 0){
var actionToRun = engine.atomStack.shift();
actionToRun[0](actionToRun[1]); } };
eventActivate = function(event) {
for (var i = 0; i < events[event].length ; i++) {
var actionAndParam = events[event][i].split('|');
translateActions(actionAndParam[0],actionAndParam[1]); } };
engine.action1 = function( param ) {
console.log("executed action 1, param "+param[0]); }
engine.action2 = function( param ) {
console.log("executed action 2, params "+param[0]+" "+param[1]); }
actions.action1 = function( param ) {
var params = param.split(';');
engine.atomStack.push([engine.action1,params]); }
actions.action2 = function( param ) {
var params = param.split(';');
params[1]=parseInt(params[1],10)+2
engine.atomStack.push([engine.action2,params]); }
translateActions = function(action, param) { actions[action](param); };
</script> </body> </html>
</code></pre>
<p>Something happens, and I need to run the actions inside an event. I call eventActivate passing the event that should happen. The function translateAction read this information and calls the function that set up the actions. My logic is based that a level contain events, an event can contain actions, and each different action contain atoms.</p>
<p>Example: at some point you call eventActivate(1) and that will push the relative events on the stack. Then from time to time the engine is used and calls engine.runatomStack() to execute whatever is there.</p>
<pre><code>//engine.atomStack is Array [ ]
eventActivate(2)
//engine.atomStack is Array [ Array[2], Array[2] ]
engine.runatomStack()
//prints:
// "executed action 2, params 5 4" example.html:18
// "executed action 2, params 2 4" example.html:18
//engine.atomStack is Array [ ]
</code></pre>
<p>Ok, so my engine start to grow and all and now I think I need to add IF/ELSE statements and WHILE/BREAK loops. I have some ideas on implementation but wanted help to what's works best using this queue. Sorry if it's duplicate, but couldn't find help using Google.</p>
<p>I thought something like, if I had events:</p>
<pre><code>4: ["action2|5;2","IF|condition","action2|2;2","END|"]
5: ["action2|5;2","IF|condition","action2|2;2","ELSE|","action1|2","END|"]
</code></pre>
<p>I'm not sure how exactly to go, what's works best...</p>

How to get offsetTop of element in regards to the document and not its parent?
|
<p>I had trouble wording my question, but here's the detail ! I've been struggling with how to get my navigation bullets (spans) to be highlighted when the current element is in viewport. I've initially tried using the same logic as a sidemenu tutorial I previously used elsewhere (by Web Cifar on youtube), but it doesn't quite work here.
If I console(log) the .bullet-slider class, they correctly show up. What the problem is, from what I gather, is the offsetTop of my const bulletSlide can't be calculated because the parentElement is another div and not the document (is this right?). I've looked into using an Intersection Observer instead, but being new to javascript I'm struggling in how I could implement it into my existing structure.</p>
<p>Any help and/or tips would be greatly appreciated ! Thank you !</p>

<li>Also, on a side note, I have N type of actors, each doing a different kind of task and managed by a different Router.</li>
</ul>
<p>Code snippet(Java)</p>
<pre><code>Config config = ConfigFactory.parseString(
"akka.remote.netty.tcp.port=" + 2551).withFallback(
ConfigFactory.load());
ActorSystem system = ActorSystem.create("CalcSystem", config);
Address[] addresses = {
AddressFromURIString.parse("akka.tcp://CalcSystem@127.0.0.1:2551"),
AddressFromURIString.parse("akka.tcp://CalcSystem@127.0.0.1:2552"),
AddressFromURIString.parse("akka.tcp://CalcSystem@127.0.0.1:2553")
};
ActorRef router = system.actorOf(
ClusterSingletonManager.props(new ClusterRouterPool(new RoundRobinPool(2),
new ClusterRouterPoolSettings(100, 3,
false, "")).props(
new RemoteRouterConfig(new RoundRobinPool(6), addresses).props(
Worker.createWorker())),PoisonPill.getInstance(),settings),"workerRouter");
ClusterSingletonProxySettings proxySettings = ClusterSingletonProxySettings.create(system);
ActorRef routerProxy = system.actorOf(ClusterSingletonProxy.props("/user/workerRouter", proxySettings), "routerProxy");
</code></pre>
<p>My doubt is regarding how make the list of Address a dynamic one? The current hardcoded list of Address won't work in production.</p>
<p>As soon as new nodes join in the cluster, Routers/ClusterSingletonManager should be able to recognize that and create remote actors on that new node(It could be a brand new node added to an already existing cluster or it could be the case of whole cluster booting up, for the very first time or in the case of new code deployments)</p>
<p>As far as my seed nodes are concerned, they are mentioned in the akka.conf file.</p>
<pre><code>akka {
actor {
provider = "akka.cluster.ClusterActorRefProvider"
}
cluster {
seed-nodes = [
"akka.tcp://CalcSystem@127.0.0.1:2551"]
}
}

Got Solution How to store the cookies in login and delete the cookies in logout action
|
<pre><code>My Problem is solved
</code></pre>
<p>I am doing an application that is getting cookies from server side. I want to store the cookies and delete the cookies at logout function but I don't know how to do this.
Based on this cookies my app has to show some additional benefits to the user so I want to save this cookies.
This is login request:</p>
<pre><code>- (IBAction)enterButtonAction:(id)sender {
NSString *post =[NSString stringWithFormat:@"user[email]=%@&user[password]=%@",userNameTF.text,passWordTF.text];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPBody:postData];

iOS Segue opening two view controllers (assuming two table cells clicked)
|
<p>When I click a table cell in my application it opens two view controllers. Which it seems to assume that I have clicked two cells, since it opens the cell before and the one I have clicked.</p>
<p>The first 3 cells are pretty much static, every other cell underneath the "ingredients" heading are dynamic. Hence why indexPath - 3</p>
<p>I created the segue between the table view and the view controller in the interface builder.</p>
<p>Table View:</p>
<p><img src="https://i.stack.imgur.com/uC2EL.png" alt="enter image description here"></p>
<p>First view controller/segue:</p>
<p><img src="https://i.imgur.com/SNnhhMl.png" alt="enter image description here"></p>
<p>Second view controller segue:</p>
<p><img src="https://i.stack.imgur.com/I0JqX.png" alt="enter image description here"></p>
<p>Code for the segue:</p>
<pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
self.selectedIngredient = self.selectedProduct.ingredientsArray[indexPath.row - 3];
[self performSegueWithIdentifier:@"ingViewSegue" sender:self];

}
#pragma mark segue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
IngredientWebViewController *webView = segue.destinationViewController;
webView.selectedIngredient = self.selectedIngredient;
}
</code></pre>
<p>Number of rows in table:</p>
<pre><code>#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [_selectedProduct.ingredientsArray count] + 3;
}
</code></pre>
<p>Code to populate table:</p>
<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

Sprite Kit delay on runAction completion?
|
<p>I'm building a game with Sprite Kit that implements A* Pathfinding. I'm using a grid system (blocks) that the character uses to calculate the path, it works great. My problem is the animation.</p>
<p>I'm using a NSMutableArray to hold the steps and removes a step each time the move has been completed (runAction completion). It works but the animation freezes for a microsecond between completion and the new move making it look "choppy", its not a smooth move...</p>
<p>I've tried a lot of things and the only thing that works is to change the duration to about 1.5 seconds to move 32px (its going to be a sloooooow game ;) ). When I want the duration I need (0.7) the problem is there.</p>
<p>I really hope someone can help me.</p>
<p>Here is some code:</p>
<pre><code>-(void)animateChar {
self.currentStepAction = nil;
if (self.pendingMove != nil) {
tileMap *moveTarget = pendingMove;
self.pendingMove = nil;
self.shortestPath = nil;
[self moveToward:moveTarget];
return;
}
if (self.shortestPath == nil) {
return;
}
// WE HAVE REACHED OUR BLOCK! CHECK IF ITS CLICKED OR STROLLING
if ([self.shortestPath count] == 0) {
self.shortestPath = nil;
self.moving = FALSE;
self.strolling = FALSE;
if (self.minionBlock) {
CGPoint diff = ccpSub(self.minionBlock.position, self.parentBlock.position);
if (abs(diff.x) > abs(diff.y)) {
if (diff.x > 0) { [self runAnimation:_faceRight speed:0.3]; } else { [self runAnimation:_faceLeft speed:0.3]; }
} else {
if (diff.y > 0) { [self runAnimation:_faceUp speed:0.3]; } else { [self runAnimation:_faceDown speed:0.3]; }
}
// SET TIMER FOR REMOVING THE BLOCK. EVERY 0.5 SECONDS IT REMOVES X ENDURANCE.
self.blockTimer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(pickBlock) userInfo:nil repeats:YES];
} else {
[self setMinionBusy:FALSE];
[self runAnimation:_waiting speed:0.3];
[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(selectRandBlockAndMove) userInfo:nil repeats:NO];
}
return;
}
ShortestPathStep *s = [self.shortestPath objectAtIndex:0];
// CHECK HOLE ON NEXT DOWN
tileMap *checkHole = [s.theBlock getNeighbor:1];
if ([checkHole isBlockType] == 2) { // THERE IS A HOLE, WE CANT REACH!
if ([_scene getRecentBlock] == self.minionBlock) { [_scene controlHud:1]; }
[self removeBlockBar];
[self.minionBlock setOccupied:FALSE];

<p>I have no problem retrieving the first attribute in my shader however, when I trying to retrieve others, It dont work. To test it, I have setup an float array and a simple shader program and I try to retrieve my position to draw a triangle.
Here is how my datas are ordered :</p>
<p><a href="https://i.stack.imgur.com/OhBjo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OhBjo.png" alt="how my datas are ordered" /></a></p>
<p>Here is my vertex shader :</p>
<pre><code>#version 400
layout (location = 0) in vec3 colors;
layout (location = 1) in vec2 textCoords;
layout (location = 2) in vec3 normals;
layout (location = 3) in vec3 positions;
out vec3 fs_colors;
void main()
{
gl_Position = vec4(positions.x, positions.y, positions.z, 1.0);
// gl_Position = vec4(colors.x, colors.y, colors.z, 1.0); //This line work, proofing my
// first attribute is sended well to my shader
fs_colors = colors;
}
</code></pre>
<p><strong>The problem is, except the first attribute, all others seems to not be sent to the shader. What am I missing ?!</strong></p>

Parameters not being read even though they appear to be passed
|
<p>I'm making a form that creates more than one record for the user depending on how many items the user decides to check off in the form using checkboxes.</p>
<p>Currently, I'm running into an error where <code>param is missing or the value is empty: itemrecord</code> even though in the log, it appears that <code>params</code> are passing through:</p>
<pre><code>{"utf8"=>"✓", "authenticity_token"=>"m2NMruoFRr6lpsuVMK9UthlY0bsJsPmf1LWce2uKaH4=", ":item_name"=>["Backpack", "Water filter"], "commit"=>"Go!"}
</code></pre>
<p>Model relationship is that a <code>User has_many :inventories</code></p>
<p>Controller code:</p>
<pre><code>def create
@itemrecord = @current_user.inventories.build
items_to_be_saved = []
inventory_params.each do |i|
items_to_be_saved << ({ :signup_id => @current_user.id, :item_name => i })
end
if Inventory.create items_to_be_saved
flash[:success] = "Thanks!"
redirect_to root_path
else
render new_inventory_path
end
end
def inventory_params
params.require(:itemrecord).permit(:item_name)
end
</code></pre>
<p>View code:</p>
<pre><code> <%= form_for @itemrecord do |f| %>
<!-- In case you're wondering, the @wishlist below is basically a hash of categories of items and items. This hash is updated in the controller, and then used by multiple views to create the same table of items. -->
<% @wishlist.each do |category, list| %>
<div class="col-xs-2">
<div class="form-group box">
<h5> <%="#{category}"%> </h5>
<% list.each do |thing| %>
<%= check_box_tag ":item_name[]", "#{thing}" %>
</br>
<% end %>
</div>
</div>
<% end %>
<%= f.submit "Go!", class: "btn btn-primary btn-large btn-block" %>
</div>
<% end %>
</code></pre>
<p>By the way I also tried changing <code>:item_name</code> to <code>:item_names</code> to account for the array based on what else I read on SO, but that didn't fix it either</p>

Nodejs microservice to SQL Server database connection timout
|
<p>I am using <a href="https://loopback.io/doc/en/lb3/" rel="nofollow noreferrer">loopback3</a> for creating Nodejs microservice.</p>
<p>I have total 7 to 8 micro services. All the micro services connecting to different SQL Server databases running on same instance (192.168.20.25:1433). I am building docker images for the micro services and running them using Kubernetes Pods on openshift cluster.</p>
<p>All of the micro services are connecting to 192.168.20.25:1433 SQL Server database properly.</p>
<p>But one of the micro services is facing the database connection timeout issue. But same code when I run on a virtual machine using "npm start" command then it's able to connect to the same db.</p>
<p>Difference here is I am running code with docker images and kubernetes pods, it's giving DB connection timeout issue. And when I am running code without docker images and kubernetes pods as normal npm start command then it works.</p>
<p>Any idea what could be the issue? Thanks in advance for help.</p>

<p>The problem I recognize is that both Ansible and Python will use the hosts.yaml file, but not use it the way I thought it would as I'm not too familiar with Ansible.</p>
<p>The hosts.yaml was written in a format that is required by Ansible.</p>
<p>The Python script will open the yaml file, make a dictionary out of it, and step through the dictionary and look for the application names to pass to the command line call. The problem is then that Python only passes the name of the app as a string to the invocation of <code>ansible-playbook</code>, the dictionary structure obviously doesn't get passed, so Ansible will then open the <code>hosts.yaml</code> file as well, but all it does is step through the yaml and look for the first occurrence of the app name that was passed as an argument when <code>ansible-playbook</code> was invoked, completely disregarding the structure I've created in the yaml file.</p>
<p>So basically only the <code>rp_1</code> group in the yaml file will be executed since Ansible, I think reads through the yaml from top down and stops at the first occurrence, therefore all or parts of the <code>rp_2</code> group will never be processed by Ansible if the group contains all or some of the same apps as <code>rp_1</code>, therefore running the same deployment twice.</p>
<p>Is there a way to invoke Ansible or some ways to set the playbooks up so that Ansible will recognize that in my hosts file, I have networks (<code>rp_1</code>, <code>rp_2</code>) that I want to setup and executes the playbooks in the grouping that I've created in the yaml file?</p>

Why does my code not work when a character is in the second row of the array?
|
<p>I have some code with a method that is trying to return the opposing character label of a 2d array's position.</p>
<p>Let's suppose the array and it's labels for each position are like below:</p>
<pre><code>{{3,3,3,3}, {3,3,3,3}}
a,b,c,d e,f,g,h
</code></pre>
<p>If b is entered, f is returned. I have it working right if a, b, c, or d is entered, but it doesn't work right if e, f, g, or h is entered and I can't figure out why.</p>
<pre><code>public class ByteTest {
public static void main(String[] args) {
int[][] testArray = {{3,3,3,3}, {3,3,3,3}};
// a b c d e f g h
char slectdPit = 'e';
int total = (int)slectdPit;
int total97 = total - 97;
System.out.println(myGetOpposingPit(slectdPit, testArray));
}
public static char myGetOpposingPit(char b, int[][] ints) {
char retChar = 'z';
int retVal = 0;
int charPosi = 0;
int total97 = 0;
for (int i = 0; i < 2; i++) {
for (int j = 0; j < ints[0].length; j++) {
charPosi = (int)b;
total97 = charPosi - 97;
if (total97 <= ints[0].length) {
if (total97 == j) {
retVal = (charPosi + ints[0].length);
retChar = (char)retVal;
}
}
else if (total97 > ints[0].length) {
if (total97 == (j + (ints[0].length))) {
retVal = (charPosi - ints[0].length);
retChar = (char)retVal;
}
}
}
}
return retChar;
}
}
</code></pre>
<p>I've made an if statement </p>
<pre><code> else if (total97 > ints[0].length) {
if (total97 == (j + (ints[0].length))) {
retVal = (charPosi - ints[0].length);
retChar = (char)retVal;
}
</code></pre>
<p>That's supposed to get find labels that are in the second row of the array, and assign returnedChar with <code>characterPosition</code> - array row length, so if the character ran through <code>myGetOpposingPit</code> is g, it'd be <code>charPosi (103) minus ints[0].length (4), equaling 99</code>, which gets <code>ascii</code> converted into 'c'.</p>
<p>Doesn't work though, <code>z</code> gets returned. So one of my if statements isn't running or something.</p>

PHP MS SQL - Fatal Error: Call to undefined function sqlsvr_connect()
|
<p>Good morning. I am trying to set up a php development environment but I keep running in circles chasing down answers that have not worked by searching.</p>
<p>The error I get when trying to run the test php file in Php Designer or after saving it and running it in Chrome or Firefox to connect to my local MS SQL Express db is:</p>
<blockquote>
<p>Fatal Error: Call to undefined function sqlsvr_connect()</p>

<p>I am using:</p>

<li>PHP Version 7.2.5 (x86)</li>

<p>The code I'm using in the test.php:</p>
<pre><code>$serverName = "DESKTOP-1FK6JRL\\SQLEXPRESS"; //serverName\instanceName
$connectionInfo = array( "Database"=>"testdb", "UID"=>"myusername", "PWD"=>"MyPassword");
$conn = sqlsrv_connect( $serverName, $connectionInfo);

}else{

}

<p>I want to add annotation to <code>step</code> attributes. As you see, I added it in <code>int1</code>. All <code>step</code> attributes (also in <code>int2</code>, <code>int4</code>...) are of different types, but have same meaning, so the annotation should be same.</p>
<p>Is there any way I could share one annotation across all <code>step</code> attributes?</p>
<p>Or define <code>step</code> externally, together with annotation and reuse it (like with <code>attributeGroup</code>), but allow for different attribute types?</p>

Unable to upload webdatacommons example file into OpenRDF Sesame 2.7.0 (seemingly) because of encoded Chinese characters
|
<p>I just tried uploading the example <a href="http://webdatacommons.org/samples/data/ccrdf.html-rdfa.sample.nq" rel="nofollow">webdatacommons RDF file</a> </p>
<p>Into Sesame 2.7.0 and get a message: </p>
<pre><code>"'洪雄熊' was not recognised as a language literal, and could not be verified, with language zh_tw [line 3931]"
</code></pre>
<p>I checked that line in the file and it is as follows:</p>
<pre><code><http://bearhungfactory.mysinablog.com/index.php> <http://creativecommons.org/ns#attributionName> "\u6D2A\u96C4\u718A"@zh_tw <http://bearhungfactory.mysinablog.com/index.php> .
</code></pre>
<p>I was wondering if there is a way to relax validation in Sesame so I could upload these files anyway? If not, can you please suggest if there is any other workaround to upload
webdatacommons into Sesame? Or is there a SPARQL endpoint to this data that I can use?</p>
<p>Here is the full exception:</p>

Improving graph quality while exporting in r
|
<p>I have written following code for comparing between to different variables over a period. The code works fine but only problem is when i output the file as "jpeg" the lines are not smooth and my arrow is not as smooth as i like it to be in other words the graph feels very low quality. But when i output it as "pdf" i get smooth lines and graph is of higher quality. But pdf files are high in file size and i need to insert these graphs in word file. I find it relatively easy to append jpeg into the word file. So is it possible to improve image quality while being in jpeg format. I tried using <code>res</code> argument in <code>jpeg()</code> but it doesnot output the graph as it is displayed in the rstudio.</p>
<p>I will appreciate the help. Thanks!</p>

Upload doesn't work using Carrierwave in Rails 5
|
<p>So I was working on my app and trying to put on an uploader feature.</p>
<p>First I generated a course uploader and allowed jpeg, jpg, png and gif. </p>
<p>Next I've added the ff code mount on my course model:</p>
<pre><code> mount_uploader :thumb_image, CoursesUploader
mount_uploader :main_image, CoursesUploader
</code></pre>
<p>Next, I place the file upload form code on my new.html.erb file:</p>
<pre><code> <div class="field">
<%= f.file_field :main_image %>
</div>
<div class="field">
<%= f.file_field :thumb_image %>
</div>
</code></pre>
<p>And when I tried to submit my form with my images uploaded it did not even show the index page instead I refresh the page and then see if it got uploaded and the form was submitted successfully but it did not. </p>
<p>I also look at the strong params on my controller and these two items are there:</p>
<pre><code> # Never trust parameters from the scary internet, only allow the white list through.
def course_params
params.require(:course).permit(:title, :price, :body, :main_image, :thumb_image)
end
</code></pre>
<p>Any idea what am I missing here?</p>
<p>Here's something I got from my terminal after submission:</p>

How to put a thread to sleep for microseconds? (invalid implementation for sleep_for in MinGW)
|
<p>Since <code>std::chrono::sleep_for</code> accepts microseconds, I expected it to be able to sleep for microseconds with some reasonable bias (sleep <em>a little</em> longer, <em>definitely</em> not shorter).</p>
<p>However, it turned out that I was wrong and it seems to be not possible with STL.
MSVC implementation of <code>sleep_for</code> makes the thread to sleep for a few milliseconds (!!!).
MinGW implementation bluntly ignores <code>sleep_for</code> command for microseconds, 1 millisecond, and have been noticed several times to wake up spuriously (though such behavior is not specified by the standard).</p>
<p>When MinGW is told to sleep for 1 millisecond, it sleeps unreasonably longer than 1 millisecond or MSVC.</p>
<p>Here is a code snippet that I use for testing</p>
<pre><code>#include <thread>

<p>I am aware that I can use busy waiting to wait for nanoseconds, but this is a no go, since I do not want to waste CPU resources.
Moreover, MinGW implementation seems to provide unpredictable results.</p>

<p>(Sorry for the messy code.)</p>
<p>These are two classes I am using to design a tank shooter game. In this portion, I am attempting to make the image rotate according to the land it is over(to appear traveling uphill or downhill) and I don't want any piece inside of the land. "LandList" is a 2D array that has a value of 2 if there is land and 1 if there is no land. Two issues is A) rotating at incorrect heights and not rotating at all points
B)Image cuts off at a certain height</p>
<p>Thank you for your help.</p>

Most efficient way to re-order my database table and display to web
|
<p>I'm new to MySQL, Just read the section of my book explaining it and now at the point where I'm applying it to the website I'm building.</p>
<p>I have the two following tables in my database:</p>
<pre><code>Table Name: Transactions
+------------------+------------+-----------+--------+
| description | date | category | amount |
+------------------+------------+-----------+--------+
| Internet | 2013-01-04 | Bills | $50.00 |
+------------------+------------+-----------+--------+
| Giant Eagle Trip | 2013-10-04 | Groceries | $30.00 |
+------------------+------------+-----------+--------+
| Car Insurance | 2013-01-04 | Bills | $90.00 |
+------------------+------------+-----------+--------+
| Starbucks | 2013-09-04 | Coffee | $5.00 |
+------------------+------------+-----------+--------+
| Giant Eagle Trip | 2013-11-04 | Groceries | $15.00 |
+------------------+------------+-----------+--------+
Table Name: Categories
+------+-----------+
| rank | Name |
+------+-----------+
| 1 | Bills |
+------+-----------+
| 2 | Groceries |
+------+-----------+
| 3 | Coffee |
+------+-----------+
</code></pre>
<p>On My website I want to take that transaction table and order it by category column. The trick is I don't want it ordered alphabetically, I want it ordered in the same order as the Categories table. The final result I have displayed below:</p>
<pre><code>+------------------+------------+-----------+--------+
| description | date | category | amount |
+------------------+------------+-----------+--------+
| Internet | 2013-01-04 | Bills | $50.00 |
+------------------+------------+-----------+--------+
| Car Insurance | 2013-01-04 | Bills | $90.00 |
+------------------+------------+-----------+--------+
| Giant Eagle Trip | 2013-10-04 | Groceries | $30.00 |
+------------------+------------+-----------+--------+
| Giant Eagle Trip | 2013-11-04 | Groceries | $15.00 |
+------------------+------------+-----------+--------+
| Starbucks | 2013-09-04 | Coffee | $5.00 |
+------------------+------------+-----------+--------+
</code></pre>
<p>I have thought of two ways to do this and they are as follows:</p>
<pre><code>//Option A: using arrays
//Get categories in correct order
$query = "select name
from Categories
order by rank";
$result = $db->query($query);
$numOfCategories = $result->num_rows;
for($i=0; $i<$numOfCategories; $i++) {
$row = $result->fetch_assoc();
$category[$i] = $row['name'];
}
//Get transactions and put in correct order
$query = "select *
from Transactions";
$result = $db->query($query);
$numOfTransactions = $result->num_rows;
for($i=0; $i<$numOfTransactions; $i++) {
$row = $result->fetch_assoc();
for($j=0; $j<$numOfCategories; $j++) {
if ($category[$j] == $row['category']) {
$tableRows[$j][] = $row;
}
}
}
//Display Table
echo "<table>\n";
for($i=0; $i<count($tableRows); $i++) {
for($j=0; $j<count($tableRows[$i]); $j++) {
echo " <tr>\n";
echo " <td>".$tableRows[$i][$j]['description']."</td>\n";
echo " <td>".$tableRows[$i][$j]['date']."</td>\n";
echo " <td>".$tableRows[$i][$j]['category']."</td>\n";
echo " <td>".$tableRows[$i][$j]['amount']."</td>\n";
echo " </tr>\n";
}
}
echo "</table><br><br>\n";
//Option B: using where in select query
//Get categories in correct order
$query = "select name
from Categories
order by rank";
$result = $db->query($query);
$numOfCategories = $result->num_rows;
for($i=0; $i<$numOfCategories; $i++) {
$row = $result->fetch_assoc();
$category[$i] = $row['name'];
}
//Get transactions and display table
echo "<table>\n";
for($i=0; $i<$numOfCategories; $i++) {
$query = "select *
from Transactions
where category = '".$category[$i]."'";
$result = $db->query($query);
for($j=0; $j<$result->num_rows; $j++) {
$row = $result->fetch_assoc();
echo " <tr>\n";
echo " <td>".$row['description']."</td>\n";
echo " <td>".$row['date']."</td>\n";
echo " <td>".$row['category']."</td>\n";
echo " <td>".$row['amount']."</td>\n";
echo " </tr>\n";
}
}
echo "</table><br><br>\n";

<p>Which way is better and why, or is there another way that is even better than the ways (maybe using index feature in MySQL that my book didn't explain in much detail and/or using prepared statements that my book also didn't explain in much detail). </p>

Generic expression for EF Core 3.1 filtering throws exception on .Any(...)
|
<p>I try to create a generic way of getting data via EF Core 3.1 with the same filtering of different children. For this, I try to extract the searched expression inside of Any(...).</p>
<pre><code>public Expression<Func<PraeparatUpdateEntity, bool>> IsToApprovePackungUpdates_Working()

{
var func = new Func<PackungUpdateEntity, bool>(e => !e.IsImported

var query = Set.Include(praeparatUpdateEntity => praeparatUpdateEntity.PackungUpdates)
.Where(IsToApprovePackungUpdates_NotWorking());
if (!trackChanges)
{
query = query.AsNoTracking();
}
return await query.ToListAsync();
}

<p>The first version is working.

<h2>******** UPDATE ********</h2>
<p>If I add AsQueryable() to my IEnumerable database children I can add my Expressions like that:</p>
<pre><code>var query = Set.Include(praeparatUpdateEntity => praeparatUpdateEntity.PackungUpdates)
.Include(praeparatUpdateEntity => praeparatUpdateEntity.SequenzUpdates)
.ThenInclude(sequenzUpdateEntity => sequenzUpdateEntity.ApplikationsartUpdates)
.Include(praeparatUpdateEntity => praeparatUpdateEntity.SequenzUpdates)
.ThenInclude(sequenzUpdateEntity => sequenzUpdateEntity.DeklarationUpdates)
.Where(IsToApprove<PraeparatUpdateEntity>()
.OrElse(entity => entity.PackungUpdates.AsQueryable().Any(IsToApprove<PackungUpdateEntity>()))
.OrElse(entity => entity.SequenzUpdates.AsQueryable().Any(IsToApprove<SequenzUpdateEntity>()))
.OrElse(entity => entity.SequenzUpdates.SelectMany(sequenzUpdateEntity => sequenzUpdateEntity.ApplikationsartUpdates).AsQueryable()
.Any(IsToApprove<ApplikationsartUpdateEntity>()))
.OrElse(entity => entity.SequenzUpdates.SelectMany(sequenzUpdateEntity => sequenzUpdateEntity.DeklarationUpdates).AsQueryable()
.Any(IsToApprove<DeklarationUpdateEntity>())));
</code></pre>
<p>and my generic Expression:</p>
<pre><code>public Expression<Func<T, bool>> IsToApprove<T>() where T : class, IUpdateEntity
{
return entity => !entity.IsImported && entity.UpdateState != EntityUpdateState.Accepted
&& entity.UpdateType != EntityUpdateType.Unchanged;
}
</code></pre>

My app keeps saying "unfortunately it has stopped". I don't know why it is crashing

<p>In my activity, the user can input numbers into a EditViews, then click a button to calculate, the result is displayed below. However, if a user edits an EditView, clicks calculate, then goes back to edit an EditView again, the app crashes when the user clicks calculate to recalculate a new total.</p>

Compute the Cartesian Distance between points in high-dimensional space optimally
|
<p><strong>Summary:</strong></p>
<p>My class SquareDistance computes the square of the Cartesian distance in four ways using methods with these names:</p>
<ol>
<li>Signed</li>
<li>UnsignedBranching</li>
<li>UnsignedDistribute</li>
<li>CastToSignedLong</li>
</ol>
<p>The first one is fastest and uses signed integers, but my data must be unsigned (for reasons given below). The other three methods start with unsigned numbers. My goal is to write a method like those in SquareDistance that takes unsigned data and performs better than the three I already wrote, as close as possible in performance to #1. Code with benchmark results follows. (unsafe code is permitted, if you think it will help.)</p>
<p><strong>Details:</strong></p>
<p>I am developing an algorithm to solve K-nearest neighbor problems using an index derived from the Hilbert curve. The execution time for the naive, linear scan algorithm grows in time quadratically with the number of points and linearly with the number of dimensions, and it spends all its time computing and comparing Cartesian distances. </p>
<p>The motivation behind the special Hilbert index is to reduce the number of times that the distance function is called. However, it must still be called millions of times, so I must make it as fast as possible. (It is the most frequently called function in the program. A recent failed attempt to optimize the distance function doubled the program execution time from seven minutes to fifteen minutes, so no, this is not a premature or superfluous optimization.)</p>
<p><strong>Dimensions</strong>: The points may have anywhere from ten to five thousand dimensions.</p>
<p><strong>Constraints</strong>. I have two annoying constraints:</p>
<ol>
<li><p>The Hilbert transformation logic requires that the points be expressed as uint (unsigned integer) arrays. (The code was written by another, is magic and uses shifts, ANDs, ORs, and the like and can't be changed.) Storing my points as signed integers and incessantly casting them to uint arrays produced wretched performance, so I must at the very least store a uint array copy of each point.</p></li>
<li><p>To improve efficiency, I made a signed integer copy of each point to speed up the distance calculations. This worked very well, but once I get to about 3,000 dimensions, I run out of memory! </p></li>
</ol>
<p>To save on memory, I removed the memoized signed integer arrays and tried to write an unsigned version of the distance calculation. My best results are 2.25 times worse than the signed integer version.</p>
<p>The benchmarks create 1000 random points of 1000 dimensions each and perform distance calculations between every point and every other point, for 1,000,000 comparisons. Since I only care about the relative distance, I save time by not performing the square root.</p>
<p>In debug mode:</p>
<blockquote>
<pre><code>SignedBenchmark Ratio: 1.000 Seconds: 3.739
UnsignedBranchingBenchmark Ratio: 2.731 Seconds: 10.212
UnsignedDistributeBenchmark Ratio: 3.294 Seconds: 12.320
CastToSignedLongBenchmark Ratio: 3.265 Seconds: 12.211
</code></pre>
</blockquote>
<p>In release mode:</p>
<pre><code> SignedBenchmark Ratio: 1.000 Seconds: 3.494
UnsignedBranchingBenchmark Ratio: 2.672 Seconds: 9.334
UnsignedDistributeBenchmark Ratio: 3.336 Seconds: 11.657
CastToSignedLongBenchmark Ratio: 3.471 Seconds: 12.127
</code></pre>
<p>The above benchmarks were run on a Dell with an Intel Core i7-4800MQ CPU @ 2.70GHz with 16 GB memory. My larger algorithm already uses the Task Parallel library for larger tasks, so it is fruitless to parallelize this inner loop.</p>
<p><strong>Question:</strong> Can anyone think of a faster algorithm than UnsignedBranching?</p>
<p>Below is my benchmark code.</p>
<p><strong>UPDATE</strong></p>
<p>This uses loop unrolling (thanks to @dasblinkenlight) and is 2.7 times faster:</p>
<pre><code>public static long UnsignedLoopUnrolledBranching(uint[] x, uint[] y)
{
var distance = 0UL;
var leftovers = x.Length % 4;
var dimensions = x.Length;
var roundDimensions = dimensions - leftovers;

var y1 = y[i];

facebook login status in sdk javascript

<p>I have a problem to get the login status of the logged in user.
The getLoginStatus Function will be not called.
I want to get the access token to get the user data.
I tried with my own APP-ID and with a game APP-ID (298553513572593).
Above you can see my code:</p>

//js.src = "http://connect.facebook.net/de_DE/all.js";
js.src = "http://connect.facebook.net/de_DE/all.js#xfbml=1&appId=APP_ID";
fjs.parentNode.insertBefore(js, fjs);

How to make the text inside of a div glow whenever you hover over the div
|
<p>Okay I have this navbar its a series of 5 divs that have text inside of them. I want to make it to where whenever I hover over a div the <code><p></code> element inside of the div will have a glow. I know all of the correct css tags to get the glow and such, but I'm stumped when it comes to the (div):hover { } css tags to recognize that I want the text inside of them to glow, not the entire div.

How to calculate a div's width and make all their sibilings adopt the biggest size so that they look consistent using CSS?

<p>I want to make several divs containing diferent strings () length inside. I want them to fit to the content, but this pose a problem: one of the various divs will contain a larger string, hence, It will be bigger in width than the others, and when applying a border, it looks awful.</p>

<p>But as you can see, they don't look consistent because I'm using <code>width:fit-content</code> instead of a fixed width.</p>
<p>Is there a way using pure CSS to calculate the biggest div's width and apply that width to others?</p>

Calculate total amount from different dropdowns selected value
|
<p>I am trying to calculate the total value of the selected value. In one row I have three options one is to select room that is one only, second is to select any one option and the same with the third column. When I am selecting options, it shows the correct "total Amount". Also on clicking on add room one new row with same options appears and there is no limit to add rows. But now what I am trying to do is When someone select values from different rows, "Total Amount" must show the total selected values. </p>
<p>Suppose, I have selected 1 room, 1st value is 5000 and 2nd value is 4000, then "Total Amount" is showing 9000. When I added one more row, in this again I selected 1 room, the 1st value is 6000 and the 2nd value is 9000. Now the " Total Amount" will show 24000 and this will work continuously on adding rows and selecting values.</p>
<p>Here is my HTML :</p>
<pre><code><table style="width: 100%;">
<tr style=" color: white;">
<th class="col-md-4 text-center" style="padding: 10px;">No. of Rooms : </th>

Why does my method return the wrong value?
|
<p>Even though my method <em>operationsNeeded</em> prints the correct value for my return-int "count1", the very next line it returns something else to my main method. I did not include the rest of my code, if needed I'd gladly provide it.
For example if <em>operationsNeeded</em> is executed 4 times, <em>count1</em> is on 4 which is printed out as well. But for reasons unknown to me the System.out.println("check: " +count1); Statement is executed 4 times like this:<br>
<strong>check: 4<br>
check: 4<br>

$scope.modal remains undefined on $ionicPlatform.ready
|
<p>I've been looking everywhere for an answer to this problem; I wouldn't mind but it was actually working earlier. I'm trying to open a modal in an Ionic App on load of the app if there is no user access token stored in localStorage.</p>
<p>This is the code I'm working with:</p>
<p>JS</p>
<pre><code>.controller('LeagueCtrl', function($scope, $ionicModal, $ionicPlatform, $cordovaOauth, Spotify, Favourites) {
$scope.favourites = Favourites.all();
$ionicModal.fromTemplateUrl('templates/login.html', {
scope: $scope,
animation: 'slide-in-up'
}).then(function (modal) {
$scope.modal = modal;
console.log($scope.modal);
});
$scope.openModal = function() {
$scope.modal.show();
};
$scope.closeModal = function() {
$scope.modal.hide();
};
...
$scope.loginSpotify = function () {
$cordovaOauth.spotify('583ac6ce144e4fcb9ae9c29bf9cad5ef', ['user-read-private']).then(function(result) {
window.localStorage.setItem('spotify-token', result.access_token);
Spotify.setAuthToken(result.access_token);
$scope.updateInfo();
//$scope.closeModal();
}, function(error) {
console.log("Error -> " + error);
});
};
$scope.updateInfo = function() {
Spotify.getCurrentUser().then(function(data) {
$scope.getUserPlaylists(data.id);
}, function(error) {
$scope.loginSpotify();
});
};
$ionicPlatform.ready(function() {
var storedToken = window.localStorage.getItem('spotify-token');
if (storedToken !== null) {
Spotify.setAuthToken(storedToken);
$scope.updateInfo();
} else {
$scope.openModal();
alert('ionicPlatform ready');
}
});
})

database file can't be found

<p>i am trying to use dataBAseHelper class to create database file, but i cant find it on data file (it stills empty). while debugging it, it seems that onCreate method doesn't been called .
i tried different databaseHelper versions,but it didnt work.<br />

Freeing dynamic 2D array not working as expected in C
|
<p>When I run code like the following:</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
int main (void)
{
int i, count = 0x09;
int sizei = 5, sizej = 2;
int **ary = malloc (sizei * sizeof **ary);
for (i = 0; i < sizei; i++) {
*(ary + i) = malloc (sizej * sizeof *(ary + i));
**(ary + i) = ++count;
printf (" %2d |%p| +%x+ \n", i, (ary + i), *(*(ary + i)));
}
puts("----");
for (i = sizei - 1; i >= 0; i--) {
printf (" %2d |%p| +%x+ \n", i, (ary + i), *(*(ary + i)));
free (*(ary + i));
}
puts("----");
free (ary);
return 0;
}
</code></pre>
<p>I would expect that the first half would create a 2d dynamic array of ints called <code>ary</code> (i.e a pointer to a dynamically allocated array of pointers, each pointing to a dynamically allocated array of ints). The 0th element of each array <code>**(ary + i)</code> would then be recursively assigned the current value of <code>count</code>.</p>
<p>The second half would iterate in reverse, freeing each element of <code>ary</code> in the reverse it was malloc'd, followed by freeing <code>ary</code> itself.</p>
<p>This appears to work fine until I try to free <code>*(ary + 0)</code>, at which point I get a double free / corruption error. I've included the output.</p>
<pre><code> 0 |0x1d6f010| +a+
1 |0x1d6f018| +b+
2 |0x1d6f020| +c+
3 |0x1d6f028| +d+
4 |0x1d6f030| +e+
----
4 |0x1d6f030| +e+
3 |0x1d6f028| +d+
2 |0x1d6f020| +c+
1 |0x1d6f018| +b+
0 |0x1d6f010| +1d6f0b0+
*** Error in `./a.out': double free or corruption (out): 0x0000000001d6f030 ***
</code></pre>
<p>I'm curious why the 0th element of the 0th element of <code>ary</code> (i.e <code>*(*(ary + 0) + 0))</code> or just <code>**ary</code>) became what looks like some memory address (only slighly) out of bounds from what's taken up by this 2d array once it got out of the first loop.</p>
<p>And if I get rid of the second loop and just try to free <code>ary</code> directly without first freeing any of its elements I get something like:</p>
<pre><code> 0 |0x1d6f010| +a+
1 |0x1d6f018| +b+
2 |0x1d6f020| +c+
3 |0x1d6f028| +d+
4 |0x1d6f030| +e+
----
*** Error in `./a.out': free(): invalid next size (fast): 0x0000000001d6f010 ***
</code></pre>
<p>I don't understand what I've done wrong here. Would using array notation make a difference? I need any solutions to allow me to have a dynamic length of each array independant of the length of the rest of the elements of <code>ary</code> if at all possible. The number elements of <code>ary</code> wouldn't necesarily be known at compile time either. I'm using gcc 4.9 if that's relevant.</p>

How to display images using foreach statement in asp.net?
|
<p>To better understand my problem, I will explain first my main goal for the website. My website is a music store which has 6 different brand of guitars(Ibanez, Fender, Gibson, PRS, Musicman and ESP). Now I've created a webpage where it will display the logo for each guitar brands.</p>
<p>Here is the aspx code for displaying the guitar logos:</p>
<pre><code><%@ Page Title='' Language='C#' MasterPageFile='~/MasterPage.master'
AutoEventWireup='true' CodeFile='GuitarBrands.aspx.cs'
Inherits='Pages_GuitarBrands' %>
<asp:Content ID='Content1' ContentPlaceHolderID='ContentPlaceHolder1'
Runat='Server'>
<% foreach (guitarBrand guitar in brandList) { %>
<table class="one-third">
<tr>
<th rowspan="3" class="guitarLogoHover">
<a href="<%= guitar.page%>"><img src="<%= guitar.image %>"/></a>
</th>
</tr>
</table>
<% } %>
</asp:Content>
</code></pre>
<p>Here is the aspx.cs code for displaying the guitar logos:</p>
<pre><code>public partial class Pages_GuitarBrands : System.Web.UI.Page
{
public List<guitarBrand> brandList { get; set; }
private string brandType = "Guitar";
protected void Page_Load(object sender, EventArgs e)
{
brandList = new List<guitarBrand>();
brandList = ConnectionClassBrands.GetBrandsByType(brandType);
}
</code></pre>
<p>The code above successfully displays all 6 guitar logos in the aspx webpage. Now the next thing to do is, when i click a guitar logo, lets say i click the Ibanez logo. it should open a new webpage and display guitars that are available within that brand. The tricky part is, I'm trying to create a single webpage for all guitar brands, which will serve like a template so that i don't need to have many aspx pages per guitar brand. Here is my attempt to this.</p>
<p>Firstly, in my connectionclass code where all the retrieving of data happens. I added a private string field named guitar that will retrieve the guitar brand everytime that it is iterating in the foreach loop.</p>
<p>Code 1 - Here is the new aspx code for displaying the guitar logos. As you can see below, i've created a string field named guitar in ConnectionClassGuitarItems to get the guitar brand.</p>
<pre><code><%@ Page Title='' Language='C#' MasterPageFile='~/MasterPage.master'
AutoEventWireup='true' CodeFile='GuitarBrands.aspx.cs'
Inherits='Pages_GuitarBrands' %>
<asp:Content ID='Content1' ContentPlaceHolderID='ContentPlaceHolder1'
Runat='Server'>
<% foreach (guitarBrand guitar in brandList) { %>
<table class="one-third">
<tr>
<th rowspan="3" class="guitarLogoHover">
<a href="<%= guitar.page%>"><img src="<%= guitar.image %>"/></a>
</th>
</tr>
</table>
<% ConnectionClassGuitarItems.guitar = guitar.name;%>//newly added code
<% } %>
</asp:Content>
</code></pre>
<p>Code 2 - Here is also the code for the ConnectionClassGuitarItems. The value that the field guitar get from the above. It will supplement the List GetGuitarItems() method so that it can identify what guitar products to retrieve.</p>
<pre><code>public static string guitar;
public static List<guitarItem> GetGuitarItems()
{
List<guitarItem> list2 = new List<guitarItem>();
BrandsDBEntities obj2 = new BrandsDBEntities();
list2 = (from g in obj2.guitarItems where g.brand == guitar select g).ToList();
return list2;
}
</code></pre>
<p>Code 3 - Now here is the aspx.cs code for displaying the guitar products. This is where i would store the retrieved products in another field called List guitarItemList so that i can supplement it in its aspx page.</p>
<pre><code>public partial class Pages_GuitarItems1 : System.Web.UI.Page
{
public List<guitarItem> guitarItemList { get; set; }
protected void Page_Load(object sender, EventArgs e)
{
guitarItemList = new List<guitarItem>();
guitarItemList = ConnectionClassGuitarItems.GetGuitarItems();
}
}
</code></pre>
<p>Code 4 - And finally here is the aspx code for displaying the guitar products.</p>
<pre><code><%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master"
AutoEventWireup="true" CodeFile="GuitarItems1.aspx.cs"
Inherits="Pages_GuitarItems1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1"
Runat="Server">
<% foreach (guitarItem gItem in guitarItemList) { %>
<div class="one-two">
<img src="<%= gItem.itemimage1 %>"/>
<div class="content">
<div id="label"><%= gItem.brand %> <%= gItem.model %></div>
</div>
</div>
<% } %>
</asp:Content>
</code></pre>
<p><strong>Now here is the problem</strong>
It is not displaying the right guitar products according to its brand. Since i've only made a single webpage for each brand, it is only displaying ESP guitar products. For example if i click the Ibanez logo, it should display Ibanez products. But in this case, when i click the Ibanez logo, it will show ESP guitar products. Same as the other brand logos, when i click it, it will only display ESP guitar products. What is wrong with the new code that i have implemented?</p>
<p>From my understanding, the foreach loop will iterate the guitar brands in this order(Ibanez,Fender,Gibson,PRS,Musicman and ESP). Please help me guys on solving this one. I've already tried several variations but its still having the same results. </p>

Oozie custom asynchronous action
|
<p>I have a problem implementing a custom asynchronous action in Oozie. My class extends from ActionExecutor, and overwrites the methods initActionType, start, end, check, kill and isCompleted.</p>
<p>In the start method, i want to to start a YARN job, that is implemented through my BiohadoopClient class. To make the call asynchronous, i wrapped the client.run() method in a Callable:</p>
<pre><code>public void start(final Context context, final WorkflowAction action) {
...
Callable<String> biohadoop = new Callable<String>() {
BiohadoopClient client = new BiohadoopClient();
client.run();
}
// submit callable to executor
executor.submit(biohadoop);
// set the start data, according to https://oozie.apache.org/docs/4.0.1/DG_CustomActionExecutor.html
context.setStartData(externalId, callBackUrl, callBackUrl);
...
}
</code></pre>
<p>This works fine, and for example when I use my custom action in a fork/join manner, the execution of the actions runs in parallel.</p>
<p>Now, the problem is, that Oozie remains in a RUNNING state for this actions. It seems impossible to change that to a completed state. The check() method is never called by Oozie, the same is true for the end() method. It doesn't help to set the context.setExternalStatus(), context.setExecutionData() and context.setEndData() manually in the Callable (after the client.run() has finished). I tried also to queue manually an ActionEndXCommand, but without luck.</p>
<p>When I wait in the start() method for the Callable to complete, the state gets updated correctly, but the execution in fork/join isn't parallel anymore (which seem logic, as the execution waits for the Callable to complete).</p>
<p><a href="https://stackoverflow.com/questions/20671386/how-external-clients-notify-oozie-workflow-with-http-callback/20680301#20680301">How external clients notify Oozie workflow with HTTP callback</a> didn't help, as using the callback seems to change nothing (well, I can see that it happened in the log files, but beside from that, nothing...). Also, the answer mentioned, that the SSH action runs asynchronously, but I haven't found out how this is done. There is some wrapping inside a Callable, but at the end, the call() method of the Callable is invoked directly (no submission to an Executor).</p>
<p>So far I haven't found any example howto write an asynchronous custom action. Can anybody please help me?</p>
<p>Thanks</p>
<p><strong>Edit</strong></p>
<p>Here are the implementations of initActionType(), start(), check(), end(), the callable implementation can be found inside the start() action.</p>
<p>The callable is submitted to an executor in the start() action, after which its shutdown() method is invoked - so the executor shuts down after the Callable has finished. As next step, context.setStartData(externalId, callBackUrl, callBackUrl) is invoked. </p>
<pre><code>private final AtomicBoolean finished = new AtomicBoolean(false);
public void initActionType() {
super.initActionType();
log.info("initActionType() invoked");
}
public void start(final Context context, final WorkflowAction action)
throws ActionExecutorException {
log.info("start() invoked");
// Get parameters from Node configuration
final String parameter = getParameters(action.getConf());
Callable<String> biohadoop = new Callable<String>() {
@Override
public String call() throws Exception {
log.info("Starting Biohadoop");
// No difference if check() is called manually
// or if the next line is commented out
check(context, action);
BiohadoopClient client = new BiohadoopClient();
client.run(parameter);
log.info("Biohadoop finished");
finished.set(true);
// No difference if check() is called manually
// or if the next line is commented out
check(context, action);
return null;
}
};
ExecutorService executor = Executors.newCachedThreadPool();
biohadoopResult = executor.submit(biohadoop);
executor.shutdown();
String externalId = action.getId();
String callBackUrl = context.getCallbackUrl("finished");
context.setStartData(externalId, callBackUrl, callBackUrl);
}
public void check(final Context context, final WorkflowAction action)
throws ActionExecutorException {
// finished is an AtomicBoolean, that is set to true,
// after Biohadoop has finished (see implementation of Callable)
if (finished.get()) {
log.info("check(Context, WorkflowAction) invoked -
Callable has finished");
context.setExternalStatus(Status.OK.toString());
context.setExecutionData(Status.OK.toString(), null);
} else {
log.info("check(Context, WorkflowAction) invoked");
context.setExternalStatus(Status.RUNNING.toString());
}
}
public void end(Context context, WorkflowAction action)
throws ActionExecutorException {
log.info("end(Context, WorkflowAction) invoked");

Modify a <p> element in a list, with jQuery
|
<p>I'm coming back here because I'm not able to do what I want. I have a nav menu, with three 'li' in one 'ul', each containing a <p> element, with the nav name.
I already have a script which hides divs and show the corresponding one, containing project thumbnails. What I would like to do, is to distinguish which nav element is active, by modifying it when it has been clicked.</p>
<p>I gave a try to modify the string of the <p> element to add a dash "-" or a point • to distinguish which was the active menu but I'm not too good with jQuery yet to manipulate a "p" in a "li" in a "ul" effectively.</p>
<p>Here is my html :</p>
<pre><code><section id="content">
<p class="section_title"> WORK </p>
<div id="sections">
<ul>
<li class="section" data-grid="grid1"><p class="navigation" style="cursor : pointer;"> Product</p></li>
<li class="section" data-grid="grid2"><p class="navigation" style="cursor : pointer;"> Mobility</p></li>
<li class="section" data-grid="grid3"><p class="navigation" style="cursor : pointer;"> Arcade Sticks</p></li>
<!-- <li class="section" data-grid="grid4"><p style="cursor : pointer;">. Infography</p></li> -->
</ul>
</div>
<!-- PROJECT GRID -->
<div id="project_grid">
<!-- PRODUCT PROJECTS -->
<div id="grid1" class="grid">
<a href="projects/product/jorislaarman.html" style="background:url('assets/img/thumbnails/jorislaarman.png')"></a>
<a href="projects/product/ptitlouis.html" style="background:url('assets/img/thumbnails/ptitlouis.png')"></a>
<a href="projects/product/diwel.html" style="background:url('assets/img/thumbnails/diwel.png')"></a>
<a href="projects/product/wirquin.html" style="background:url('assets/img/thumbnails/wirquin.png')"></a>
<a href="projects/product/ulna.html" style="background:url('assets/img/thumbnails/ulna.png')"></a>
<a href="projects/product/envol.html" style="background:url('assets/img/thumbnails/envol.png')"></a>
</div>
</code></pre>
<p>There are other grids following, each manipulated by the jQuery, here :</p>
<pre><code>$("#project_grid div:not(#grid1)").hide();
$('.section').click(function() {
$('.grid').hide();
$('#' + $(this).data('grid')).show();
});
</code></pre>
<p>I tried several things with the jQuery there, without alterating the original script, to at least underline the clicked <p> element, such as :</p>
<pre><code>$('.navigation').click(function(){
$('p').css("text-decoration","underlined");
});
</code></pre>
<p>and : </p>
<pre><code>$('p').clicked(function(){
$(this).css('text-decoration','underlined');
});
</code></pre>
<p>But none of this works :/ And I can't really figure it out.</p>
<p>I also tried to modify the <p> string, with .append, but I couldn't figure it out ether...</p>
<p>I'd just like to do something simple. Either underline the active nav section, either add a "•" before product, mobility, or arcade stick section when they have been clicked. And of course disappear when another one is clicked.</p>
<p><a href="http://jsfiddle.net/g32Vm/" rel="nofollow">http://jsfiddle.net/g32Vm/</a></p>

What is the purpose of creating "Mappings" in CloudFormation?
|
<p>See the code below:</p>
<pre><code>Mappings:

</code></pre>
<p>There is more to this code however I've only included the relevant snippets for the question.</p>
<p>To summarize - why include mappings for bucketname when the bucketname is set directly, using region and account ID in the 'Resources' section?</p>
<p>There is use of the <code>Fn::FindInMap</code> function which is used here as part of the <code>ExecutorLambdaFunction</code>:</p>
<pre><code>ExecutorLambdaFunction:
Type: AWS::Lambda::Function

RadioGroup not updating bound value
|
<p>I am using a <code>radiogroup</code> in my form, and I noticed that when I select one of the radio buttons, the value (bound value) is not updated.</p>
<p>Here's a small example:</p>
<pre><code>Ext.create({
xtype: 'container',
renderTo: Ext.getBody(),
items: [{
xtype: 'formpanel',
viewModel: {
data: {
myValue: 3
}
},
items: [{
xtype: 'displayfield',
label: 'This is the value of myValue:',
bind: '{myValue}'
}, {
xtype: 'textfield',
label: 'Update myValue:',
bind: '{myValue}'
}, {
xtype: 'radiogroup',
vertical: true,
label: 'Click a radio button:',
bind: '{myValue}',
items: [{
label: 'One',
value: 1
}, {
label: 'Two',
value: 2
}, {
label: 'Three',
value: 3
}, ]
}]
}]
});
</code></pre>
<p>I created a simple <code>viewModel</code> with one data value: <code>myValue: 3</code>. This is bound to all of the form elements: the <code>radiogroup</code>, a <code>textfield</code>, and a <code>displayfield</code>.</p>
<p>I'd expect that when I click one of the radio buttons, that the <code>displayfield</code> would update its value. The <code>displayfield</code> value is updated when you type into the <code>textfield</code>, but the <code>radiogroup</code> is not updated.</p>
<p>It seems like the <code>radiogroup</code> is only using its bound value when it initializes, but it doesn't notice when it gets updated nor does it update it on its own.</p>
<p>What am I doing wrong? Why doesn't the bound value get updated when I click on a radio button?</p>
<p>Here's an example over on Sencha Fiddle: <a href="https://fiddle.sencha.com/#view/editor&fiddle/389i" rel="nofollow noreferrer">https://fiddle.sencha.com/#view/editor&fiddle/389i</a></p>
<hr />
<p>UPDATE: I found a solution adding a <code>change</code> listener to the <code>radiogroup</code>. Well, this fixes updating <code>myValue</code> wen you click on a radio button. I'd need another listener to update the <code>radiogroup</code> when <code>myValue</code> is updated elsewhere (like in the <code>textfield</code>).</p>
<p>This works for my needs, but why should I need to add a <code>change</code> listener? Why doesn't the <code>radiogroup</code> bind to <code>{myValue}</code> correctly?</p>
<pre><code>listeners: {
change: function(field, val) {
let vm = field.lookupViewModel();
vm.set('myValue', val);
}
}
</code></pre>

Windows Server 2012 IIS8 Performance over Server 2003 IIS6, Sporadic slowness with WebService
|
<p>We had a few .NET 1.1 projects hosted on IIS6 in Server 2003. I was tasked with porting these projects to .NET 4.0 and host them on new Server 2012 VM's. Ported the code and getting it to run on Server 2012 IIS8 was no problem, but I started seeing performance problems throughout the day and they would over time resolve themselves. I have the APP Pools set to recycle every 4 hours, so I can't see it being an unhealthy app pool.</p>
<p>The config of the app pool is as follows;</p>
<p>Managed Pipeline Mode: Classic Mode
Start Mode: Always Running
Enable 32-bit Applications: True
Memory Limit: 0 (Unlimited)</p>
<p>The OS config is as follows;</p>
<p>Server 2012
Dedicated web server, no other services running.
4 virtual processors
10gb Ram
10gb Virtual NIC</p>
<p>For the webservice itself, its a simple webservice that hits a database and it also calls another webservice hosted on the same web server. I have the hostname listed in the host file, so its not doing a DNS lookup. The database is pretty much sitting idle. To give you an idea on how often this service is utilized, we had about 40k web service calls yesterday.</p>
<p>I wrote a program that tested the web service every 10 seconds for a 24 hour period. The results were kind of interesting. The times listed below are when the response times were slow and the "slow" was always consistent. The slow response times were about 6000ms, or 6 seconds. The time in between the times listed below were 200ms, or .2 seconds. </p>
<p>8:18AM - 8:36AM – 18 minutes</p>
<p>9:02AM - 9:10AM – 8 minutes</p>
<p>9:36AM - 9:47AM – 11 minutes</p>
<p>10:17AM - 10:26AM – 9 minutes</p>
<p>10:41AM - 10:56AM – 14 minutes</p>
<p>11:16AM - 11:22AM – 6 minutes</p>
<p>11:48AM - 11:56AM – 8 minutes</p>
<p>12:23PM - 12:31PM – 8 minutes</p>
<p>12:53PM - 1:00PM – 7 minutes</p>
<p>1:07PM - 1:19PM – 12 minutes </p>
<p>1:41PM - 1:47PM – 6 minutes</p>
<p>2:03PM - 2:52PM – 49 minutes</p>
<p>3:15PM - 3:34PM – 19 minutes</p>
<p>3:57PM - 4:02PM – 6 minutes</p>
<p>4:20PM - 4:26PM – 6 minutes </p>
<p>4:35PM - 4:56PM – 21 minutes</p>
<p>5:17PM - 5:25PM – 8 minutes</p>
<p>6:02PM - 6:16PM – 14 minutes</p>
<p>6:49PM - 7:00PM – 11 minutes</p>
<p>7:41PM - 7:55PM – 14 minutes </p>
<p>8:36PM - 8:51PM – 16 minutes </p>
<p>9:31PM - 9:45PM - 14 minutes</p>
<p>10:26PM - 10:41PM – 15 minutes</p>
<p>11:25PM - 11:41PM – 16 minutes</p>
<p>12:28AM - 12:45AM – 17 minutes</p>
<p>1:34AM - 1:53AM – 19 minutes</p>
<p>2:42AM - 3:02AM – 20 minutes</p>
<p>3:49AM - 4:08AM – 19 minutes</p>
<p>5:01AM - 5:15AM – 14 minutes</p>
<p>6:03AM - 6:22AM – 19 minutes</p>
<p>7:12AM - 7:28AM – 16 minutes</p>
<p>8:07AM - 8:18AM – 11 minutes</p>
<p>I can't find the culprit of the slow downs. We did not have any performance problems hosting on iis6, so it can't be the database.</p>
<p>Thoughts? </p>

Cannot set ImageView by Capture Camera from Intent.createChooser

<p>I had look for <code>"Caused by: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=234, result=-1, data=Intent { }} to activity"</code> but not luck for it, also it may relating to the log <code>selectedImage = NULL</code>.</p>
<p>Please show me any idea or advise for it.

phonegap - should navigator work in the browser?
|
<p>I'm just trying to get phonegap/cordova working. Should the Navigator's function be working in the android emulator? When i do the geolocation getcurrentposition function, it doesn't do anything. </p>
<p>When i try the navigator.notification.alert() in the browser and emulator, it doesn't work. It says that navigator.notification.alert() isn't defined. </p>
<p>I have no idea what the problem is. I would have figured it would have at least shown a browser alert. </p>

JIT deoptimization, reason="constraint". Why JIT deoptimizes method?
|
<p>could someone point me in direction which might lead me to get why JIT deoptimizes my loop? (OSR). It looks like it gets compiled once by C1 and then its deoptimized multiple times (I can see tens or maybe hundred logs which starts with <deoptimized...>)</p>
<p>This is the class which contains that important loop:</p>
<pre class="lang-java prettyprint-override"><code>@SynchronizationRequired
public class Worker implements Runnable
{
private static final byte NOT_RUNNING = 0, RUNNING = 1, SHUTDOWN = 2, FORCE_SHUTDOWN = 3;

private volatile int isRunning = NOT_RUNNING;
private final Queue<FunkovConnection> tasks = new SpscUnboundedArrayQueue<>(512);
/**

*/
@Override

{

{

}

{

{
connection.run();
}
}

return;
}
FunkovConnection connection;
while ((connection = tasks.poll()) != null)
{
connection.run();
}
setNonRunning();
}

{
tasks.add(connection);
}
/**

{
isRunningFieldUpdater.compareAndSet(this, RUNNING, SHUTDOWN);
}

<p>Two questions here:</p>
<ol>
<li>What could be the reason for deoptimization? "constraint" seems not that meaningful to me</li>
<li>Why there is so many logs about deoptimization, not just one? It look likes it's compiled once but decompiled multipile times</li>
</ol>

Javasript function to change a HTML class of a <div>, render, then continue running the rest of the function code
|
<p>I am learning programming HTML/CSS/Javascript. I created a webpage and a javascript code to get some information within an Access database then render it to user. It is a big table sometimes.
I just want to update a class and an innerHTML at the beginning and in the end of the code, in order to show to the user: "Wait, page is loading"... and after the code runs, change the class and innerHTML to nothing ("") then the message to user would disappear.</p>
<p>I did the code, but when my function runs, it is not rendering the changes to class and innerHTML until the functions is finished... </p>
<p>JUST FOR INFORMATION: At this point, the HTML is already rendered. The Javascript will act from a button click on the page.</p>
<p>My HTML - The classes and innerHTML I want to update with Javascript code.</p>
<pre><code> <section>
<div id="RunningCode" class="">
<span id="RunningCode1" class=""></span>
</div>
</section>

Not receiving PHP contact form submissions
|
<p>I was wondering if you guys can figure out why I'm not receiving my contact form submissions. I tested it out with my secondary email but still haven't received it. I tried looking for answers here in SO and on Google but can't find any solution. I have 3 questions.</p>
<p>It is my code?
Or did I not properly setup my Apache?
Is my php code secure from spam?</p>
<p>here's my code:</p>
