JavaScript Safari - SyntaxError: Unexpected token '>' | <p>I have the problem that this JavaScript snippet runs in Firefox / Chrome without any problem, and Safari I get error: "SyntaxError: Unexpected token '>'".</p>
<p>Here's the code:</p>
<pre><code>window.onclick = (test) => {
const googleWindow = window.open();
fakeAjax(response => {
googleWindow.location.replace(`https://google.com?q=${response}`);
});
};
function fakeAjax(callback) {
setTimeout(() => {
callback('example');
}, 1);
}
</code></pre>
<p>I've googled and have already seen here in the forum, the problem there appears often, unfortunately I have not found a suitable solution.</p>
<p>Thank you in advance

Margin-bottom not working in flexbox | <p>I have an issue where I have a flexbox, but I don't exactly want every single element to be spaced according to the properties given, so I want to play with margins.</p>
<p>I have a header at the top of the box but I want spacing between it and the rest of the elements.</p>
<p>So I want my list of <code>p</code> elements to be grouped together but spaced farther away from the heading.</p>
<p>However, when I do <code>margin-bottom</code> it isn't having an effect (when I increase or decrease <code>margin-bottom</code> nothing changes).</p>
<p>I was originally doing it in percents and changed it to pixels but that doesn't seem to be the issue either.</p>
<p>In the snippet I would have no problem with how it looks but on a bigger browser there's hardly any space between the heading and the <code>p</code> elements which is the issue. </p>

Running Jupyter with multiple Python and IPython paths | <p>I'd like to work with Jupyter notebooks, but have had difficulty doing basic imports (such as import matplotlib). I think this was because I have several user-managed python installations. For instance: </p>
<pre><code>> which -a python
/usr/bin/python
/usr/local/bin/python
> which -a ipython
/Library/Frameworks/Python.framework/Versions/3.5/bin/ipython
/usr/local/bin/ipython
> which -a jupyter
/Library/Frameworks/Python.framework/Versions/3.5/bin/jupyter
/usr/local/bin/jupyter
</code></pre>
<p>I used to have anaconda, but removed if from the ~/anaconda directory. Now, when I start a Jupyter Notebook, I get a Kernel Error:</p>
<pre><code>File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py",

How do I import a Groovy class into a Jenkinfile? | <p>How do I import a Groovy class within a Jenkinsfile? I've tried several approaches but none have worked.</p>

react native - requiring unknown module | <p>I have been trying to load local image files in ListView. </p>
<p>It does work when I hard code:</p>
<p><code>return <Image source={require('./public/image1.png')} style={{width: 60, height: 60}}/></code></p>
<p>However, it doesn't work when I read the path of the image like this:</p>
<pre><code>var path = rowData.thumbnail;
console.log(path); // './public/image1.png'
return <Image source={require(path)} style={{width: 60, height: 60}}/>
</code></pre>
<p>or like this:</p>
<pre><code>return <Image source={require(rowData.thumbnail)} style={{width: 60, height: 60}}/>
</code></pre>
<p>with this error message,</p>
<blockquote>
<p>Requiring unknown module"'./public/image1.png'". If you are sure the module is there, try restarting the packager or running "npm install".</p>
</blockquote>
<p>Could you please give me an advice to read the path from the object? I attached the full code below. Thank you in advance.</p>
<pre><code>class MyClass extends Component {
constructor(props) {
super(props);
const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
let data = importedData.map(function(d) {
return {
thumbnail: "'./public" + d.thumbnail + "'"
}
});
this.state = {
dataSource: ds.cloneWithRows(data)
};
}
renderRow(rowData) {
var path = rowData.thumbnail;
return <View style={{flex: 1, flexDirection: 'row'}}>
<Image source={require(path)} style={{width: 60, height: 60}}/>

Trying to understand Python loop using underscore and input | <p>One more tip - if anyone is learning Python on HackerRank, knowing this is critical for starting out.</p>
<p>I'm trying to understand this code:</p>
<pre><code> stamps = set()
for _ in range(int(input())):
print('underscore is', _)
stamps.add(raw_input().strip())
print(stamps)
</code></pre>
<p>Output:</p>
<pre><code> >>>2
underscore is 0
>>>first
set(['first'])
underscore is 1
>>>second
set(['second', 'first'])
</code></pre>
<ol>
<li><p>I put 2 as the first raw input. How does the function know that I'm only looping twice? This is throwing me off because it isn't the typical...for i in xrange(0,2) structure. </p></li>
<li><p>At first my thinking was the underscore repeats the last command in shell. So I added print statements in the code to see the value of underscore...but the values just show the 0 and 1, like the typical loop structure.</p></li>
</ol>
<p>I read through this post already and I still can't understand which of those 3 usages of underscore is being used. </p>
<p><a href="https://stackoverflow.com/questions/5893163/what-is-the-purpose-of-the-single-underscore-variable-in-python">What is the purpose of the single underscore "_" variable in Python?</a></p>
<p>I'm just starting to learn Python so easy explanations would be much appreciated!</p> | 0 |

Updating NPM with Nodist | <p>I'm unable to update <code>npm</code>, and get it to use with <a href="https://github.com/marcelklehr/nodist" rel="nofollow noreferrer">Nodist</a>.</p>
<p>Whenever I try to update <code>npm</code> with the command</p>
<pre><code>npm install -g npm
</code></pre>
<p>the following message comes right after executing it:</p>
<blockquote>
<p>(node:5304) fs: re-evaluating native module sources is not supported.
If you are using the graceful-fs module, please update it to a more recent version.</p>
<p>C:\Program Files (x86)\Nodist\v\nodev6.5.0\npm -> C:\Program Files (x86)\Nodist\v\nodev6.5.0\node_modules\npm\bin\npm-cli.js</p>
<p>[email protected] C:\Program Files (x86)\Nodist\v\nodev6.5.0\node_modules\npm</p>
</blockquote>
<p>Doing an <code>npm -v</code> right after, gives me the previous version:</p>
<pre><code>...> npm -v
2.14.10
</code></pre>
<p>However, if you noticed the last line in the message above, there is <code>[email protected]</code> which means it is somehow trying to install <em>that</em> version of <code>npm</code>.</p>
<p>I also followed instructions from <a href="https://askubuntu.com/questions/562417/how-do-you-update-npm-to-the-latest-version"><em>this</em></a> post for Ubuntu users and <a href="https://stackoverflow.com/questions/18412129/how-do-i-update-node-and-npm-on-windows"><em>this</em></a> for Windows users, but they seem to address issues with standalone <code>NodeJS</code> installations and <em>NOT</em> <code>NodeJS</code> + Nodist combo.</p>
<p>Meanwhile, I was wondering if Nodist itself enables us to update <code>npm</code>, or in other words, does it have any version management feature for <code>npm</code> as well, just as it does for <code>node</code>.</p>
<p>Thanks for any help in advance.</p>

<h3>Additional Info</h3>
<p>I am using Nodist <code>v0.7.1</code> on Windows 7.</p> | 0 |
How to install openjdk "1.8.0_20-b26" on amazon Linux? | <p>I'm pretty new to Linux and I need to install openjdk <strong>1.8.0_20-b26</strong> (that specific version) on a machine in AWS.

How to fetch and reuse the CSRF token using Postman Rest Client | <p>I am using Postman Rest client for hitting the rest services. I am getting the following error when I try to execute the rest service from Postman client.</p>

JPA insert object if not exists, do nothing if exists | <pre><code>@Entity

logger.error("Error while createItem", e);
System.err.println(e.getMessage());
}finally {
if(em!=null)
em.close();
}
}
</code></pre>
<p>I have 2 situation:
1) I create new object <code>PropertyValuesData</code>, which contain existing property (with id) -> then I want to ONLY add new <code>PropertyValuesData</code>
2) I create new object <code>PropertyValuesData</code>, with new property -> then I want to insert also new <code>PropertyData</code>.</p>
<p>If I add <code>CascadeType.PERSIST</code>, then I can save new property, but for existing property it try insert it again. What should I do to avoid insert again the same property?</p> | 0 |
RecyclerView creating margins between items | <p>first of all, sorry if this a stupid question. I'm not being lazy.
So, the problem is, im trying to implement CardView/RecyclerView in an Android app. I made it, but the problem is that the cards are spaced one from another, and i don't know how to fix it. I explored the code but everything seems to be fine.</p>
<p>The code : </p>
<p>RecyclerView</p>
<pre><code><android.support.v7.widget.RecyclerView
android:id="@+id/collapsing_recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:padding="@dimen/activity_horizontal_margin">
</android.support.v7.widget.RecyclerView>
</code></pre>
<p>CardView item</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.CardView
android:id="@+id/card_view"
card_view:cardBackgroundColor="@color/colorAccent"
android:layout_gravity="center"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:layout_margin="5dp"
card_view:cardCornerRadius="2dp">
<TextView
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="New Text"
android:id="@+id/cardview.name" />
</android.support.v7.widget.CardView>
</LinearLayout>
</code></pre>
<p>Adapter :</p>
<pre><code>public class MyRecyclerViewAdapter extends RecyclerView
.Adapter<MyRecyclerViewAdapter
.DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private ArrayList<CardViewItem> mDataset;
private static MyClickListener myClickListener;
public static class DataObjectHolder extends RecyclerView.ViewHolder
implements View
.OnClickListener {
TextView label;
public DataObjectHolder(View itemView) {
super(itemView);
label = (TextView) itemView.findViewById(R.id.cardview_name);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
}
@Override
public void onClick(View v) {
myClickListener.onItemClick(getAdapterPosition(), v);
}
}
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;
}
public MyRecyclerViewAdapter(ArrayList<CardViewItem> myDataset) {
mDataset = myDataset;
}
@Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.example_card_view, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
return dataObjectHolder;
}
@Override
public void onBindViewHolder(DataObjectHolder holder, int position) {
holder.label.setText(mDataset.get(position).getName());;
}
public void addItem(CardViewItem dataObj, int index) {
mDataset.add(index, dataObj);
notifyItemInserted(index);
}
public void deleteItem(int index) {
mDataset.remove(index);
notifyItemRemoved(index);
}
@Override
public int getItemCount() {
return mDataset.size();
}
public interface MyClickListener {
public void onItemClick(int position, View v);
}
}
</code></pre>
<p>Hope you guys can help me. Thanks!</p>
<p>EDIT: So, i found the answer. The coulprit was the android:layout_height="match_parent"
in my cardview item. I change it for "wrap_content" and fixed the problem. Thanks for the help guys! :)</p> | 0 |
Angular2 - TypeError: this.http.get(...).toPromise is not a function | <p>i try to follow tutorial on angular.io (<a href="https://angular.io/docs/ts/latest/tutorial/toh-pt6.html" rel="noreferrer">Tour the Heroes</a>)
But instead of tutorial I try to make real GET request on some JSON.</p>
<p>My code looks like:</p>
<pre><code> private userUrl = 'https://jsonplaceholder.typicode.com/users';
constructor(private http: Http) {}
getUsersHttp(): Promise<User[]> {
return this.http.get(this.userUrl)
.toPromise()
.then(response => response.json().data as User[])
.catch(this.handleError);
}
</code></pre>
<p>To service I import just few basic things:</p>
<pre><code>import { Injectable } from '@angular/core';
import { Headers, Http, Response } from '@angular/http';
import { User } from './user';
</code></pre>
<p>Where <code>user.ts</code> is basicly copy of <code>heroe.ts</code> in TOH so:</p>
<pre><code>export class User {
id: number;
name: string;
}
</code></pre>
<p>How I call this specific method in service:
First I try multiple things but while debugging i try just console.log it so:</p>
<pre><code> console.log(this.userService.getUsersHttp());
</code></pre>
<p>When page is loading in console i found multiple errors:
First one is:</p>
<blockquote>
<p>EXCEPTION: TypeError: this.http.get(...).toPromise is not a function</p>
</blockquote>
<p>Second one is:</p>
<blockquote>
<p>EXCEPTION: TypeError: this.http.get(...).toPromise is not a
functionBrowserDomAdapter.logError @</p>
</blockquote>
<p>Service it self looks fine. I added my service to <code>app.module.ts</code> in this line:</p>
<pre><code>providers: [ HTTP_PROVIDERS, UserService ]
</code></pre>
<p>and it works if I directly return data with some function like (and comment out calling <code>getUsertHttp</code> function):</p>
<pre><code> getUsers() {
return [{'id': 1, 'name': 'User1'}, {'id': 2, 'name': 'User2'}];
}
</code></pre>
<p>I try to describe everything which may be important so sorry if question is kind long a bit.
<strong>Please guys can you give me hint what i am doing wrong?</strong></p> | 0 |

What is the variable $(MAKE) in a makefile? | <p>I am currently learning how to write makefiles. I've got the following makefile (which was automatically generated for a C-project that should run on an ARM chip), and I'm trying to understand it:</p>

<p>I cannot find a definition for the variable <code>$(MAKE)</code>, so I assume that it is something built-in. What is this line actually doing?</p> | 0 |
Change popup menu style - not working | <p>I'm trying to apply style to Android popup menu. Menu is shown on button click. In my example I want to set black menu background.</p>
<p>So, my menu layout:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:title="Item 1"
android:id="@+id/menu1">
</item>
<item
android:title="Item 2"
android:id="@+id/menu2">
</item>
</menu>
</code></pre>
<p>Next, my activity layout:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.michal.popupmenu.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="@+id/button"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:onClick="btnClick"
android:nestedScrollingEnabled="true"/>
</RelativeLayout>
</code></pre>
<p>Code to show menu on button click:</p>
<pre><code>public class MainActivity extends AppCompatActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void btnClick(View view)
{
showMenu(view);
}
public void showMenu(View v)
{
PopupMenu popup = new PopupMenu(this, v);
popup.inflate(R.menu.popup_menu);
popup.show();
}
}
</code></pre>
<p>Styles xmle was generated automatically. I have only added menu style to set black menu background, here it is:
</p>
<pre><code><style name="PopupMenu" parent="Widget.AppCompat.PopupMenu">
<item name="android:popupBackground">@android:color/black</item>
</style>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="popupMenuStyle">@style/PopupMenu</item>
</style>
</code></pre>
<p></p>
<p>But still menu background is white and it should be black. Any ideas what's wrong?</p>
<p>[edit]
According to comments, updated code:</p>
<pre><code><resources>
<style name="PopupMenu" parent="@style/Widget.AppCompat.Light.PopupMenu">
<item name="android:popupBackground">#FF4081</item>
</style>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
</resources>
</code></pre>
<p>Main activity:</p>
<pre><code>public void showMenu(View v)
{
Context wrapper = new ContextThemeWrapper(getApplicationContext(), R.style.PopupMenu);
PopupMenu popup = new PopupMenu(wrapper, v);
// This activity implements OnMenuItemClickListener
//popup.setOnMenuItemClickListener((PopupMenu.OnMenuItemClickListener) this);
popup.inflate(R.menu.popup_menu);
popup.show();
}
</code></pre>
<p>Result is not what I expect</p>
<p><a href="https://i.stack.imgur.com/uepk1.png" rel="noreferrer"><img src="https://i.stack.imgur.com/uepk1.png" alt="result"></a></p>

Make padding responsive | <p>I just started using Bootstrap, and I'm new in front-end development in general. I'm having a problem with padding, since it remains the same size in desktop and mobile devices.</p>
<p>HTML code:</p>
<pre><code> <div class="container" id="i-container">
<h3>We possess high quality products &mdash; therefore our customers are always loyal</h3>
</div>
</code></pre>
<p>CSS code:</p>
<pre><code> #i-container{
border: solid;
border-color: rosybrown;
padding-left: 150px
padding-top: 10px;
}
</code></pre>
<p>As I mentioned above, in mobile devices the padding remains the same (it doesn't seem to be responsive). I tried using <em>em</em> too, by the way. It doesn't help either.</p> | 0 |

How can I add an assembly binding redirect to a .net core unit test project? | <p>I'm trying to create a .net core unit test project against framework 4.6.1 which tests an project dependent on Microsoft.SqlServer.Types (10.0.0.0).

ASP.Net Core localization | <p>ASP.Net core features <a href="https://docs.asp.net/en/latest/fundamentals/localization.html" rel="noreferrer">new support for localization</a>.</p>
<p>In my project I need only one language. For most of the text and annotations I can specify things in my language, but for text coming from ASP.Net Core itself the language is English.</p>
<p>Examples:</p>
<ul>
<li>Passwords must have at least one uppercase ('A'-'Z').</li>
<li>Passwords must have at least one digit ('0'-'9').</li>
<li>User name '[email protected]' is already taken.</li>
<li>The E-post field is not a valid e-mail address.</li>
<li>The value '' is invalid.</li>
</ul>
<p>I've tried setting the culture manually, but the language is still English.
</p>
<pre><code>app.UseRequestLocalization(new RequestLocalizationOptions
{
DefaultRequestCulture = new RequestCulture("nb-NO"),
SupportedCultures = new List<CultureInfo> { new CultureInfo("nb-NO") },
SupportedUICultures = new List<CultureInfo> { new CultureInfo("nb-NO") }
});

How to display Table in README.md file in Github? | <p>I want to display a table in readme.md file. I read <a href="https://help.github.com/enterprise/11.10.340/user/articles/github-flavored-markdown/" rel="noreferrer">GitHub Flavored Markdown</a> and followed what it said. So this is my table:</p>
<pre><code>| Attempt | #1 | #2 | #3 | #4 | #5 | #6 | #7 | #8 | #9 | #10 | #11 | #12 |
| :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: |

Replace all error values of all columns after importing datas (while keeping the rows) | <p>An Excel table as data source may contain error values (#NA, #DIV/0), which could disturbe later some steps during the transformation process in <a href="https://support.office.com/en-us/article/Introduction-to-Microsoft-Power-Query-for-Excel-6e92e2f4-2079-4e1f-bad5-89f6269cd605" rel="noreferrer">Power Query</a>.<br>
Depending of the following steps, we may get no output but an error. So how to handle this cases?</p>
<p>I found two standard steps in Power Query to catch them:</p>
<ul>
<li><a href="https://msdn.microsoft.com/en-us/library/mt260807.aspx" rel="noreferrer">Remove errors</a> (UI: Home/Remove Rows/Remove Errors) -> all rows with an error will be removed </li>
<li><a href="https://msdn.microsoft.com/en-us/library/mt260833.aspx" rel="noreferrer">Replace error values </a>(UI: Transform/Replace Errors) -> the columns have first to be selected for performing this operations.</li>
</ul>
<p>The first possibility is not a solution for me, since I want to keep the rows and just replace the error values. </p>
<p>In my case, my data table will change over the time, means the column name may change (e.g. years), or new columns appear. So the second possibility is too static, since I do not want to change the script each time.</p>
<p>So I've tried to get a dynamic way to clean all columns, indepent from the column names (and number of columns). It replaces the errors by a null value.</p>
<pre><code>let
Source = Excel.CurrentWorkbook(){[Name="Tabelle1"]}[Content],
//Remove errors of all columns of the data source. ColumnName doesn't play any role
Cols = Table.ColumnNames(Source),
ColumnListWithParameter = Table.FromColumns({Cols, List.Repeat({""}, List.Count(Cols))}, {"ColName" as text, "ErrorHandling" as text}),
ParameterList = Table.ToRows(ColumnListWithParameter ),
ReplaceErrorSource = Table.ReplaceErrorValues(Source, ParameterList)
in
ReplaceErrorSource
</code></pre>
<p>Here the different three queries messages, after I've added two new column (with errors) to the source:<br>
<a href="https://i.stack.imgur.com/F0nIC.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/F0nIC.jpg" alt=""></a></p>

Spring boot @CachePut, how it works | <p>I'm trying to update values in spring cache, however @CachePut does not replace actual value, but put another value with the same key:</p>
<p>Cachename: noTimeCache:</p>
<ul>
<li>Key: SYSTEM_STATUS, val: ON</li>
<li>Key: SYSTEM_STATUS, val: OFF</li>
</ul>
<p>1.Why?</p>
<p>My cache service:</p>
<pre><code>@CachePut(value = "noTimeCache", key = "#setting.getSetting().name()")
public String updateGlobalCacheValue(GlobalSettings setting) {
System.out.println("Setting: " + setting.getSetting().name() + ", val: " + setting.getValue());
return setting.getValue();
}
</code></pre>
<p>I know it's looks funny but i need to work with jpa repositories. Maybe someone have better solution.</p>
<p>2.Why can't I use function argument as @Cacheable key like this?</p>
<pre><code>@Cacheable(value = "noTimeCache", key = "#setting.name()", unless = "#result == null")
@Query("SELECT gs.value FROM GlobalSettings gs WHERE gs.setting = ?1")
String getGlobalSettingValue(Settings setting);
</code></pre>
<p>It tells me setting is null.</p>
<p>3.Is the way to override @Repositository interface methods, for example save() to add annotation @Cacheable to them?</p> | 0 |

How conditional join if first matching has no row, use second matching | <p>My client table has some special rows that work this way. There are multiple customer records that belongs to the same customer but with slightly different column value. The tables belong to them and I can't change anything in their table, so I have to work on a script to deal with this.</p>
<p>Now I need to compare customer data from main table and get the data from client table. The condition is as below:</p>
<ol>
<li><p>If the main table Id exists in client table, get the only record matching with main table Id column</p></li>
<li><p>If the main table Id not exists in client table, use main table Idnumber to find and match Idnumber in client table. </p></li>
</ol>
<p>Below is an example of what I'm trying to achieve:</p>
<p>Let's say this data exist in the main table and client table below:</p>
<p><a href="https://i.stack.imgur.com/0ju23.png" rel="noreferrer"><img src="https://i.stack.imgur.com/0ju23.png" alt="enter image description here"></a></p>
<p>In the scenario above, my script should always pick the client table PKId 1 only and ignore the row PKId 2 in client table by matching the main table Id column and client table ClientId column. </p>
<p>And for another scenario below:</p>
<p><a href="https://i.stack.imgur.com/WE9Sx.png" rel="noreferrer"><img src="https://i.stack.imgur.com/WE9Sx.png" alt="enter image description here"></a></p>
<p>Since the row PKId 1 has empty ClientId and there's no way to match the client Id 10 in client table, my script should use main table Idnumber to find and match record in the client table and would pick up the row PKId 2 by the Idnumber column.</p>
<p>I wanted to do a case in the join condition but not sure how I should construct it. I'm thinking about something like below (not actual SQL statement, just some idea):</p>
<pre><code>Select
c.Id, c.Name, c.AuthorizeToken
From
Client c
Left Join
Main m on (If m.Id = c.ClientId has data return, get AuthorizeToken from that row only;
else if m.Id = c.ClientId has no data return, use m.Idnumber = c.Idnumber
to find and get AuthorizeToken)
</code></pre>
<p>Appreciate if can advice me on any alternative to achieve this. </p> | 0 |
Media queries + browser zoom | <p>I've come across a super weird problem when it comes to media queries and browser zoom.</p>
<p>I'm using Chrome 52.0.2743.116 m.</p>
<p>The issue is this:</p>
<p>When you zoom in using the browser zoom to 125% and resize the browser until tablet is supposed to kick in (max-width: 1024px), there seems to be a moment where neither max-width: 1024px or min-width: 1025px is true.</p>
<p>If I change it to max-width: 1024.9px - it works.</p>
<p>Here's a quick example:</p>
<pre><code><div class="box">
Text
</div>
<div class="box">
Text
</div>
<div class="box">
Text
</div>
</code></pre>
<p>And the CSS:</p>
<pre><code>@media (max-width:768px) {
.box {
background: blue;
}
}
@media (min-width: 769px) and (max-width: 1024px) {
.box {
background: red;
}
}
@media (min-width:1025px) {
.box {
background: green;
}
}
</code></pre>
<p>Example: <a href="http://codepen.io/tomusborne/pen/EyrNvG" rel="nofollow">http://codepen.io/tomusborne/pen/EyrNvG</a></p>
<p>Zoom in 125%, then resize down until it turns red. Resize up pixel by pixel, and you'll notice there's no background color at all for one pixel between tablet and desktop.</p>
<p>Anyone know what's going on here? Is using 1024.9px a decent solution? Am I just going crazy?</p> | 0 |
Execute stored procedure using entity framework | <p>is it possible to execute a stored procedure using EF, that select records from database from two or more tables using inner join and left outer join.</p>
<p>my point of view is to avoid the method of doing joins in EF or LINQ, which i have many issues with it. </p>
<p>so if i create that procedure, can i call it with parameters from user input, can assign the result to <code>.ToList()</code> method and then add the result to asp:repeater <code>.DataSource</code>. </p>
<p>I know it may be a strange question, but i want to do this for many reasons
first, to use EF because i feel more comfortable.
second, to get rid of using joins in EF.
third, i read somewhere that using stored procedure will enhance query performance, when used to call a query frequently.</p>
<p>if any one could help me to answer these questions with an example i would be appreciate. </p> | 0 |
How to display image from rails local project folder? | <p>Very basic question, but somehow I can't get it to work. I am trying to have an image located in project's local folder to display on Rails. Additionally, I am using bootstrap; thus I need to declare <code>class: "img-responsive"</code> as well. Here is the original code: <code><img class="img-responsive" src="assets/img/mockup/img2.jpg" alt=""></code></p>
<p>I have consulted <a href="https://stackoverflow.com/questions/31368682/how-to-use-the-image-tag-with-bootstrap-class-img-responsive-chapter-11">this post</a> which suggested <code><%= image_tag("xyz.png", class: "img-responsive img-thumbnail img-circle") %></code> and <a href="http://api.rubyonrails.org/classes/ActionView/Helpers/AssetTagHelper.html" rel="nofollow noreferrer">rubyonrails guide</a> which suggested <code>image_tag("/icons/icon.gif", class: "menu_icon")</code>.</p>
<p>I have tried</p>
<pre><code><%= image_tag ("assets/img/mockup/img2.jpg", class: "img-responsive")%>
</code></pre>
<p>and</p>
<pre><code><%= image_tag "assets/img/mockup/img2.jpg" %>
</code></pre>
<p>But it still does not work.
I can confirm that the path is: <code>app/assets/img/mockup/img2.jpg</code></p>
<p>How can I display the said image on rails app view?</p> | 0 |
Not able to write Spark SQL DataFrame to S3 | <p>I have installed spark 2.0 on EC2 & I am using SparkSQL using Scala to retrieve records from DB2 & I want to write to S3, where I am passing access keys to the Spark Context..Following is my code :</p>

"Result of method is ignored"- what does this imply? | <p>For some methods I get the warning. This is what it says when expanded.
The following code (<code>mkDirs()</code>) gives the warning</p>
<pre><code>if (!myDir.exists()) {
myDir.mkdirs();
}
</code></pre>
<blockquote>
<p>Reports any calls to specific methods where the result of that call is ignored. Both methods specified in the inspection's settings and methods annotated with org.jetbrains.annotations.Contract(pure=true) are checked. For many methods, ignoring the result is perfectly legitimate, but for some methods it is almost certainly an error. Examples of methods where ignoring the result of a call is likely to be an error include java.io.inputStream.read(), which returns the number of bytes actually read, any method on java.lang.String or java.math.BigInteger, as all of those methods are side-effect free and thus pointless if ignored.</p>

Python 2.7 [Errno 113] No route to host | <p>I have 2 computers on the same LAN. The first PC has an ip address 192.168.178.30, the other PC has an ip address 192.168.178.26.
Ping, traceroute, telnet, ssh, everything works between the two PCs. Both PCs run the same OS - CentOS 7 and both PCs have the same python version 2.7.5 (checked with the python -V command).</p>
<p>I copied simple python code from a computer networking book. </p>
<p>client.py</p>
<pre><code>from socket import *

serverPort = 12000
clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect((serverName,serverPort))
sentence = raw_input('Input lowercase sentence: ')
clientSocket.send(sentence)
modifiedSentence = clientSocket.recv(1024)
print 'From Server:', modifiedSentence
clientSocket.close()

<p>server.py</p>
<pre><code>from socket import *

@ViewChild in *ngIf | <h2>Question</h2>
<p>What is the most elegant way to get <code>@ViewChild</code> after corresponding element in template was shown?</p>
<p>Below is an example. Also <a href="http://plnkr.co/edit/xAhnVVGckjTHLHXva6wp?p=preview" rel="noreferrer">Plunker</a> available.</p>
<p><strong>Component.template.html:</strong></p>
<pre class="lang-html prettyprint-override"><code><div id="layout" *ngIf="display">
<div #contentPlaceholder></div>
</div>
</code></pre>
<p><strong>Component.component.ts:</strong></p>
<pre class="lang-js prettyprint-override"><code>export class AppComponent {
display = false;
@ViewChild('contentPlaceholder', { read: ViewContainerRef }) viewContainerRef;
show() {
this.display = true;
console.log(this.viewContainerRef); // undefined
setTimeout(() => {
console.log(this.viewContainerRef); // OK
}, 1);
}
}
</code></pre>
<p>I have a component with its contents hidden by default. When someone calls <code>show()</code> method it becomes visible. However, before Angular 2 change detection completes, I can not reference to <code>viewContainerRef</code>. I usually wrap all required actions into <code>setTimeout(()=>{},1)</code> as shown above. Is there a more correct way?</p>
<p>I know there is an option with <code>ngAfterViewChecked</code>, but it causes too much useless calls.</p>

JSON add node to an existing JObject | <p>I am trying to add a new node to an existing <code>JSON</code> <code>JObject</code>, but when I add it does not format correctly. It adds quotes around the entire node, and \ are put in place.</p>

<pre><code>mainJson.Add("NewNode", JsonConvert.SerializeObject(MyObject));
File.WriteAllText("myfile.json", mainJson.ToString());
</code></pre>
<p>Problem is that this is the result:</p>

"More": "Nodes",
"InThe": "File"
}
],
"Customers": "{\"FirstName\":\"Mike\",\"LastName\":\"Smith\"},{\"FirstName\":\"Jane\",\"LastName\":\"Doe\"}",
}

<p>I know that my JsonConvert.SerializeObject(MyObject) is working if I do this:</p>
<pre><code>string json = JsonConvert.SerializeObject(MyObject);
File.WriteAllText("myfile2.json" json);

<p>The result is this:</p>
<pre><code>[
{
"FirstName": "Mike",
"LastName": "Smith"

{
"FirstName": "Jane",

</div>
</script>
</code></pre>
<p>The user have to fill an input number in a range of <code>info.max</code> to <code>info.min</code>.</p>
<p>Here the relevant angular code - Triggering the modal window opening:</p>
<pre><code>function gotoPageDialog(fileNo, current, max) {
var modalInstance = $uibModal.open({
templateUrl: 'myModalContent.html',
controller: 'ModalInstanceCtrl',
size: 'sm',
resolve: {
current_info: function() {

max: max,
min: 1

modalInstance.result.then(function(result) {
//...
};
}
}
</code></pre>
<p>And the modal window it self:</p>
<pre><code>app.controller('ModalInstanceCtrl', function($scope, $uibModalInstance, current_info) {
$scope.info = current_info;
$scope.ok = function() {
$uibModalInstance.close($scope.info);
};
$scope.cancel = function() {
$uibModalInstance.dismiss('cancel');
};
});
</code></pre>
<p>The result is:</p>
<p><a href="https://i.stack.imgur.com/RgtSY.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/RgtSY.jpg" alt="enter image description here"></a></p>
<p>The input value is "-1", What's mean that the <code>ng-min</code> and <code>ng-max</code> range is not working.</p>
<p>What I'm doing wrong?</p>

How to to return an image with Web API Get method | <p>I need to return an image with a Web API Get method. The code below seems to work fine except that I get this message in the Fiddler's ImageView window, "This response is encoded, but does not claim to be an image." </p>
<pre><code>public HttpResponseMessage Get()
{
using (FileStream fs = new FileStream(filePath, FileMode.Open))
{
HttpResponseMessage response = new HttpResponseMessage();
response.Content = new StreamContent(fs);
response.Content.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");
return response;
}
}
</code></pre>
<p>I see the same result in the Fiddler with this code also:</p>
<pre><code>public HttpResponseMessage Get()
{
HttpResponseMessage response = new HttpResponseMessage();
Byte[] b = (GetImageByteArray());
response.Content = new ByteArrayContent(b);
response.Content.LoadIntoBufferAsync(b.Length).Wait();
response.Content.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");
return response;
}
</code></pre>
<p>I get the same result if I use .png format. </p>

pyinstaller creating EXE RuntimeError: maximum recursion depth exceeded while calling a Python object | <p>I am running WinPython 3.4.4.3 with pyinstaller 3.2 (obtained via pip install pyinstaller).</p>
<p>Now I've got some really simple Qt4 code that I want to convert to EXE and I've run into problem that I cannot solve. </p>
<p><strong>The Code:</strong></p>
<pre><code>import sys
import math
from PyQt4 import QtGui, QtCore
import SMui
import numpy as np
from scipy.interpolate import InterpolatedUnivariateSpline
class SomeCalculation(QtGui.QMainWindow, SMui.Ui_MainWindow):
def __init__(self):
super(self.__class__, self).__init__()
self.setupUi(self)
self.setWindowTitle('Some Calculation')
self.calculate.clicked.connect(self.some_math)
def some_math(self):
a_diameter=self.a_diameter.value()
b_diameter=self.b_diameter.value()
complement=self.complement.value()
angle=self.angle.value()
preload=self.preload.value()
### ONLY MATH HAPPENS HERE also defining X and Y ####
interpolator = InterpolatedUnivariateSpline(X, Y)
### MORE MATH HAPPENS HERE ####
self.axial.setText(str(axial))
self.radial.setText(str(radial))
def main():
app = QtGui.QApplication(sys.argv)
window=SomeCalculation()
window.show()
app.exec_()
if __name__=='__main__':
main()
</code></pre>
<p>I try to run <code>pyinstaller file_name.py</code> and I'm getting:</p>
<pre><code>RuntimeError: maximum recursion depth exceeded while calling a Python object
</code></pre>
<p>Now if there's a few things that I have found out that also affect the issue:</p>
<p>1) If I comment out this line: <code>from scipy.interpolate import InterpolatedUnivariateSpline</code></p>
<p>2) Creating EXE file from another different script that uses Scipy.Interpolate (RBS, but still) - works like a charm.</p>
<p>3) If I try to convert it to EXE using WinPython 3.5.1.1 + pyinstaller obtained the same way, and it's the same 3.2 version of it - it generates my exe file no problems. </p>
<p>I want to understand what's causing the error in the original case and I cannot find any answer on google unfortunately, most of the fixes I could find were related with matplotlib and not interpolation though. </p> | 0 |

How to convert a string to an array using Ruby on Rails | <p>I have a text field that takes in a string value, like</p>
<pre><code>"games,fun,sports"
</code></pre>
<p>My main goal here is to take the string and turn it into a Array like this:</p>
<pre><code>[games, fun, sports]
</code></pre>
<p>in the filters attribute for the integrations object I have. Right now I have the beginning of a method that doesn't seem to work.</p>
<p>Here is my code:</p>
<p>View:</p>
<pre><code> <%= form_for @integrations, url: url_for(:controller => :integrations, :action => :update, :id => @integrations.id) do |f| %>
<%= f.label :filters %>
<%= f.text_field :filters, class: "filter-autocomplete" %>
<%= f.submit "Save" %>
<% end %>
</code></pre>
<p>That is the text field that takes in the string.</p>
<p>Model:</p>
<pre><code>def filters=(filters)
end
</code></pre>
<p>This is the place that I'd like to make the switch from string to array.</p>
<p>Controller:</p>
<pre><code> def update
@integrations = current_account.integrations.find(params[:id])
if @integrations.update_attributes(update_params)
flash[:success] = "Filters added"
redirect_to account_integrations_path
else
render :filters
end
end
def filters
@integrations = current_account.integrations.find(params[:id])
end
private
def update_params
[:integration_webhook, :integration_pager_duty, :integration_slack].each do |model|
return params.require(model).permit(:filters) if params.has_key?(model)
end
end
</code></pre>
<p>So, recap: I have a integrations model that takes in a string of filters. I want a method that will break up the string into an element of filter attributes. </p>
<p>Here is the object that I'm trying to add the filters to:</p>
<p>Object:</p>
<pre><code> id: "5729de33-befa-4f05-8033-b0acd5c4ee4b",
user_id: nil,
type: "Integration::Webhook",
settings: {"hook_url"=>"https://hooks.zapier.com/hooks/catch/1062282/4b0h0daa/"},
created_at: Mon, 29 Aug 2016 03:30:29 UTC +00:00,
owner_id: "59d4357f-3210-4ddc-9cb9-3c758fc1ef3a",
filters: "[\"Hey\", \"ohh\"]">
</code></pre>
<p>As you can see the <code>filters</code> is what I'm trying to modify. Instead of this in the object:</p>
<pre><code>"[\"Hey\", \"ohh\"]"
</code></pre>
<p>I would like this: </p>
<pre><code>[Hey, ohh]
</code></pre> | 0 |

Java Entity Manager - JSON reader was expecting a value but found 'db' | <p>I have this code already working:</p>
<pre><code>EntityManager entityManager = getEntityManager();
entityManager.getTransaction().begin();
String query = "db.Band.find({})";
List<Band> list = (List<Band>) entityManager.createNativeQuery(query, Band.class).getResultList();
entityManager.close();
return list;
</code></pre>
<p>It returns a <code>List</code> with no problem. Now I want to sort that <code>List</code> by <code>date</code>:</p>
<pre><code>EntityManager entityManager = getEntityManager();
entityManager.getTransaction().begin();
String query = "db.Band.find({something__id:ObjectId(\"" + myId + "\")}).sort({\"somethingelse.date\":-1})";
List<Band> list = (List<Band>) entityManager.createNativeQuery(query, Band.class).getResultList();
entityManager.close();
return list;
</code></pre>
<p>My console gives me this message:</p>
<pre class="lang-none prettyprint-override"><code>org.bson.json.JsonParseException: JSON reader was expecting a value but found 'db'
</code></pre>
<p>I checked that my <code>String</code> was working properly in Mongo console and it did. Any ideas?</p>
<p>Edit: I tried putting "something__id" between quotes because it wouldn't work even without the sort part if I didn't (I just realised that), but now it says I am making an unsupported native query, pointing out the Sort part. Should I sort it after I already have it in a List object?</p> | 0 |

Angular2-Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource | <p>I am calling a http post in Angular 2.

Angular 2 do not refresh view after array push in ngOnInit promise | <p>I created a NativeScript app with angular 2, i have an array of objects that i expect to see in the frontend of the application. the behaviour is that if i push an object into the array directly inside the ngOnInit() it works, but if i create a promise in the ngOnInit() it doesn't work. here is the code:</p>
<pre><code>export class DashboardComponent {
stories: Story[] = [];
pushArray() {
let story:Story = new Story(1,1,"ASD", "pushed");
this.stories.push(story);
}
ngOnInit() {
this.pushArray(); //this is shown
var promise = new Promise((resolve)=>{
resolve(42);
console.log("promise hit");
});
promise.then(x=> {
this.pushArray(); //this is NOT shown
});
}
}
</code></pre>
<p>the relative html is: </p>
<pre><code><Label *ngFor="let story of stories" [text]='story.message'></Label>
</code></pre>
<p>when the app starts i see only one push, but than i created a button that trigger a "console.log(JSON.stringify(this.stories));" and at that moment, when i tap the button, the ui seems to detects the changed array, and the other pushed object appears.</p>
<p><strong>EDIT:</strong></p>
<p>I created a more simple example in this thread: <a href="https://stackoverflow.com/questions/39203004/angular-2-when-i-change-a-variable-in-a-promise-than-in-ngoninit-the-view-doesn">Angular 2: when i change a variable in a promise.than in ngOnInit the view doesn't refresh</a></p> | 0 |
How to add more than one `tools:replace` in Android Manifest Application? | <p>I'm using a library that has the below in its Manifest.</p>
<pre><code><application android:allowBackup="true"
android:label="@string/app_name"
android:supportsRtl="true"/>
</code></pre>
<p>However, as the application that I use to include the library the reverse of the setting instead</p>
<pre><code><application android:allowBackup="false"
android:label="@string/app_name"
android:supportsRtl="false"/>
</code></pre>
<p>Hence it would have merger error like <a href="https://stackoverflow.com/questions/39178130/is-androidsupportsrtl-true-in-the-library-manifest-essential-it-is-causing">Is `android:supportsRtl="true"` in the Library Manifest essential? It is causing error sometimes</a></p>
<p>To solve it, we just need to add the following to our Manifest application.</p>
<pre><code>tools:replace="android:supportsRtl"
</code></pre>
<p>and</p>
<pre><code>tools:replace="android:allowBackup"
</code></pre>
<p>However, adding two <code>tools:replace</code> will have error in compilation. How could I combine the two <code>tools:replace</code>?</p>
<p>I tried the below, and it's not working.</p>
<pre><code>tools:replace="android:supportsRtl|android:allowBackup"

<p>This works fine locally. But once we publish to Azure, this fails. I'm at a loss. I've created new .Net core project that deploy to Azure just find. But this one project, that I put all my time into to, seems to fail. I'm about ready to copy and paste code out of the project that fails to run and into a new project, but i'm really curious on what's breaking this.</p>
<p>Any ideas?</p>
<p>EDIT:
So my Program.cs was:</p>
<pre class="lang-cs prettyprint-override"><code>using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Hosting;
namespace Quanta.API
{
public class Program
{
public static void Main(string[] args)
{
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
}
}
</code></pre>
<p>Edit2:
Per Frans, I checked the publishOptions. It was:</p>
<pre><code>"publishOptions": {
"include": [
"wwwroot",
"web.config"
]
</code></pre>
<p>I took a publishOptions from a working project and changed it to:</p>
<pre><code> "publishOptions": {
"include": [
"wwwroot",
"Views",
"Areas/**/Views",
"appsettings.json",
"web.config"
]
},
</code></pre>
<p>It still gave a 500 error, but it didn't give a stack trace saying it coulding load appsettings.json. Now it was complaining about a connection to SQL. I noticed that my SQL connection string code is mentioned in a lot of RC1 blog posts. RC2 of .Net Core changed it. So I updated it to:</p>
<pre><code> "Data": {
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\MSSQLLocalDB;Database=QuantaDb;Trusted_Connection=True;MultipleActiveResultSets=true"
}
},
</code></pre>
<p>And changed my startup to:</p>
<pre class="lang-cs prettyprint-override"><code> services.AddDbContext<QuantaContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"),
b => b.MigrationsAssembly("Quanta.API")));
</code></pre>
<p>Finally, it worked. </p>
<p>I must have followed an older RC1 example and not realized it.</p> | 0 |

I am getting a 404 error on my new Reactjs app, is it looking for a main.js file? | <p>This app should be rendering what I have here (/Users/ldco2016/Projects/reactquiz/src/components/App.jsx:</p>

Change checked attribute of controlled checkbox (React) | <p>I am new to React and am probably lacking the correct terminology to find a solution to my problem. It cannot be that hard.</p>
<p>I am building a simple app which displays a set of questions, one question at a time. After answering one question, the next question is shown. </p>
<p>I have a component <code>Question</code> that renders 3 checkboxes, each checkbox represents one possible <code>answer</code> to the Question.</p>
<pre><code>{this.props.question.answers.map((answer, index) => {
return (
<li className="Question__answer" key={answer.id}>
<label className="Question__answer-label">
<input
className="Question__answer-checkbox"
type="checkbox"
value={index}
onChange={this.props.setAnswer}
defaultChecked={false} />
{answer.answer}
</label>
</li>
...
<button className="Question__next" type="button" onClick={this.props.onNext} disabled={this.props.isDisabled}>
Next question
</button>
)
})}
</code></pre>
<p>Inside my main component <code>Quiz</code> I call the component like this:</p>
<p><code><Question step={this.state.step} question={this.state.questions[this.state.step]} setAnswer={this.setAnswer} onNext={this.onNext} isDisabled={this.isDisabled()} /></code></p>
<p><code>onNext</code> is my function which increments <code>this.state.step</code> in order to display the next question:</p>
<pre><code>onNext(event) {
this.setState({step: this.state.step + 1});
}
</code></pre>
<p>Everything works fine, except: When the next question is displayed, I want all 3 checkboxes to be unchecked again. Currently they remember their checked state from the previously answered question.</p> | 0 |
child_process exits with code null | <p>I am running my node server in centos6.X, and forking a child process.</p>
<pre><code>var cp = require('child_process');
child = cp.fork(__dirname+'/worker');
child.on('exit', function (code, signal) {
console.log('Child exited with code = ' +code+' signal = '+signal);
});
</code></pre>
<p>but after few seconds I get this error </p>
<blockquote>
<p>Child exited with code = null signal = SIGKILL</p>
</blockquote>
<p>I am now clueless how to get rid of this, there is no more trace, as to what is happening.</p>
<p><strong>more clarification</strong></p>
<p>I have put console.logs in worker and they are getting printed. the worker is now waiting for message from main server. but exits after waiting for few seconds. I also run the worker js independently with node command and there it does not exit.</p>
<p>The same code works fine on my local OSX laptop. but on cloud centos6.X I am facing this issue.</p> | 0 |

Define `become=yes' per role with Ansible | <p>In my system provisioning with Ansible, I don't want to specify <code>become=yes</code> in every task, so I created the following <em>ansible.cfg</em> in the project main directory, and Ansible automatically runs everything as root:</p>

become = True

How to maintain Firebase Auth for multiple pages on the web? | <p>I am using Firebase for a web application. The goal is to allow a familiar log-in/sign-up where the user signs up or logs in one one page, and upon successful authentication, is brought to the home page.</p>
<p>The flow would look something like this:
Log-in/Sign-up -> (allows access to) -> [Home, Profile, Search, Friends, etc.]</p>
<p>I am using Javascript (No AngularJs since I am unfamiliar with it entirely). The problem I am having is that once the user successfully logs in or signs up, their "user object" becomes null on using
<code>window.location = 'home.html'</code> </p>
<p>Here is the complete code. I am using the sample found Firebase for now for the authentication process, but the home.html is my doing:</p>

Python Matplotlib FuncAnimation.save() only saves 100 frames | <p>I am trying to save an animation I've created with the FuncAnimation class in Matplotlib. My animation is more complicated, but I get the same error when I try to save the simple example given <a href="https://stackoverflow.com/questions/16732379/stop-start-pause-in-python-matplotlib-animation">here</a>.</p>
<pre><code>import matplotlib.pyplot as plt
import numpy as np
import matplotlib.animation as animation
pause = False
def simData():
t_max = 10.0
dt = 0.05
x = 0.0
t = 0.0
while t < t_max:
if not pause:
x = np.sin(np.pi*t)
t = t + dt
yield x, t
def onClick(event):
global pause
pause ^= True
def simPoints(simData):
x, t = simData[0], simData[1]
time_text.set_text(time_template%(t))
line.set_data(t, x)
return line, time_text
fig = plt.figure()
ax = fig.add_subplot(111)
line, = ax.plot([], [], 'bo', ms=10) # I'm still not clear on this stucture...
ax.set_ylim(-1, 1)
ax.set_xlim(0, 10)
time_template = 'Time = %.1f s' # prints running simulation time
time_text = ax.text(0.05, 0.9, '', transform=ax.transAxes)
fig.canvas.mpl_connect('button_press_event', onClick)
ani = animation.FuncAnimation(fig, simPoints, simData, blit=False, interval=10,
repeat=True)
plt.show()
</code></pre>
<p>However, when I try to save this animation by adding the line</p>
<pre><code>ani.save('test.mp4')
</code></pre>
<p>at the end, only the first 100 frames are saved.</p>
<p>After the animation is saved, the function restarts and displays as expected, displaying and updating the figure 200 times (or until t reaches t_max, whatever I set that to be). But the movie that is saved only contains the first 100 frames.</p>
<p>The pause functionality makes it tricky. Without it I could just put in frames = 200 into the FuncAnimation call rather that using the iterator/generator type function I currently have for the frames argument. But by just putting in frames = 200, the frame count seems to be un-pauseable. </p>
<p>How can I fix this?</p> | 0 |

Check if list contains another list in R | <p>I want to check if a list (or a vector, equivalently) is contained into another one, not if it is a subset of thereof. Let us assume we have</p>
<pre><code>r <- c(1,1)
s <- c(5,2)
t <- c(1,2,5)
</code></pre>
<p>The function should behave as follows:</p>
<pre><code>is.contained(r,t)
[1] FALSE
# as (1,1) is not contained in (1,2,5) since the former
# contains two 1 whereas the latter only one.
is.contained(s,t)
[1] TRUE
</code></pre>
<p>The operator <code>%in%</code> checks for subsets, hence it would return <code>TRUE</code> in both cases, likewise <code>all</code> or <code>any</code>. I am sure there is a one-liner but I just do not see it.</p> | 0 |

Java equivalent of C# Delegates (queues methods of various classes to be executed) | <p>TLDR:</p>
<p>Is there a Java equivalent of C#'s <a href="http://www.tutorialsteacher.com/csharp/csharp-delegates" rel="noreferrer">delegates</a> that will allow me to queue up methods of various classes and add them to the queue dynamically? Language constructs instead of the code for it.</p>
<p>Context:</p>
<p>I have used Unity 3D before and I love things like the <code>Update</code> method of scripts. Just declaring the method adds it to the list of methods executed each frame. I want to create something like that in my LWJGL game. For this, I would want to use delegates (or something equivalent to it). Is there any Java language construct that would allow me to do this? I would prefer answers that include two or more (so that I can pick and choose which will be the most optimal for my code) constructs and a way of using them. I don't want the code, I just want to know where to start. The most fun part of programming is working the problem out and I don't want to be deprived of that. Also, I don't want to be told EXACTLY how to do it. I want to be guided in the right direction instead of being thrown in that direction onto that destination. How would I learn? :-)</p> | 0 |

How get sum of total values in stackedBar ChartJs | <p>I'm trying to get the sum of all values of a stackedBar and include this total in tooltip.</p>

<pre><code>var barChartData = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [{
label: 'Corporation 1',

data: [50, 40, 23, 45, 67, 78, 23]
}, {
label: 'Corporation 2',
backgroundColor: "rgba(151,187,205,0.5)",
data: [50, 40, 78, 23, 23, 45, 67]
}, {
label: 'Corporation 3',
backgroundColor: "rgba(151,187,205,0.5)",
data: [50, 67, 78, 23, 40, 23, 55]

responsive: true,
scales: {
xAxes: [{
stacked: true,
}],
yAxes: [{
stacked: true
}]
}
}
});
};
</code></pre>
<p>Now <code>total</code> is the sum per dataset and I need the sum per stackedBar.</p>
<p>Example</p>
<p>Label A: value A</p>
<p>Label B: value B</p>
<p>Label C: value C</p>
<p>TOTAL: value A + value B + value C</p>
<p>It is possible to get that total value?</p>

Is there a limit on the number of indexes that can be created on Elastic Search? | <p>I'm using AWS-provided Elastic Search.</p>

How to switch to a new remote git repository | <p>I've recently cloned a repo to my local drive, but now I'm trying to push all changes to a complete new repo. However, git keeps telling me that permission is denied, and that's because it's trying to push to the originally-cloned repo.</p>
<p>DETAILS:</p>
<p>I originally cloned from <a href="https://github.com/taylonr/intro-to-protractor" rel="noreferrer">https://github.com/taylonr/intro-to-protractor</a> (i.e. based on a Pluralsight course at <a href="https://app.pluralsight.com/library/courses/protractor-introduction/table-of-contents" rel="noreferrer">https://app.pluralsight.com/library/courses/protractor-introduction/table-of-contents</a> ) .</p>
<p>Now that I've completed the course, I'd like to push my finalized code up to my own git repo (which I just created on github): </p>
<p><a href="https://github.com/robertmazzo/intro-to-protractor" rel="noreferrer">https://github.com/robertmazzo/intro-to-protractor</a></p>
<p>When I use the following git command: </p>
<blockquote>
<p>git remote add origin <a href="https://github.com/robertmazzo/intro-to-protractor.git" rel="noreferrer">https://github.com/robertmazzo/intro-to-protractor.git</a></p>
</blockquote>
<p>it tells me <code>remote origin already exists</code> , which I guess is fine because I already created it on github.com.</p>
<p>However, when I push my changes up I'm getting an exception.</p>
<blockquote>
<p>git push origin master</p>
</blockquote>
<p><code>remote: Permission to taylonr/intro-to-protractor.git denied to robertmazzo.
fatal: unable to access 'https://github.com/taylonr/intro-to-protractor.git/':
The requested URL returned error: 403</code></p>
<p>So I'm investigating how I can switch to my new repository, but this is exactly where my issue is. I cannot figure this part out.</p> | 0 |

${rowList} = evaluate [item.get_attribute('text') for item in ${elList}] selenium

<p>I can't understand the problem here; BTW I'll appreciate any other solution for my issue.</p>

<p>However after a lot of tears, sweat and pleading to all the deities I could come up with... I still remain with what is hopefully the last error in a series of many:</p>
<p><strong>No provider for ConnectionBackend!</strong></p>
<p>At this point I am tearing out the last strains of hair I have left as I am clueless at this point regarding the "what I am missing".</p>

What is data-bound properties? | <p>I am trying to understand OnInit functionality in angular2 and read the documentation: </p>
<blockquote>
<p>Description</p>
<p>Implement this interface to execute custom initialization logic after
your directive's data-bound properties have been initialized.</p>
<p>ngOnInit is called right after the directive's data-bound properties
have been checked for the first time, and before any of its children
have been checked. It is invoked only once when the directive is
instantiated.</p>
</blockquote>
<p>I do not understand <code>directive's data-bound properties</code> what does it mean? </p> | 0 |
