React Native horizontal FlatList with multiple rows : <p>I'm trying to implement a horizontal scrolling list that has two rows. Using FlatList, the vertical scrolling list involves setting <code>numColumns</code> but there is no equivalent for using rows with horizontal.</p>
<p>I was successfully able to make it render properly, and it works flawlessly. However, a warning gets thrown saying setting <code>flexWrap</code> is not supported in <code>VirtualizedList</code> or <code>FlatList</code>, and to use numColumns. I cannot use numColumns as that is not meant for horizontal lists.</p>
<pre><code><FlatList
horizontal={true}
contentContainerStyle={{
flexDirection: 'column',
flexWrap: 'wrap'
}}
{...otherProps}
/>
</code></pre>
<p>I found the commit where this warning was added, but cannot find the reasoning behind it. There seems to be no way to make this work without a warning being thrown, at least without ditching FlatList entirely. Is there a more appropriate solution for horizontal lists with rows?</p>

Completely Stuck. Create Dual Sidebar With Expanding Options. [Diagram Provided] : I have spent about an hour trying to find a solution that can work, however, none of them come close to my desired goal. I am not expecting someone to spend the time creating it for me (its a lot of work), but I want to know how I can achieve it. Links or js fiddle would be amazing.
So this sidebar I am working on. It should have three states.
---------------------
The first and second state show up on table onwards.
The default state is when the sidebar is loaded.
[Default state][1]
-------------
The second state is what happens when the user clicks on one of the icon images that are seen in the first image. It now expands to show the additional navigation. (Ex. Icon says Friends, and the new menu that appears has a list of like 10 people).
[Clicked State][2]
--------------
The Third state only appears on mobile. It basically eliminated the icon sidebar seen in the Default State (first image)
[Cant show Mobile Picture Cause I need 10 reputation :| I will comment below.]
-----------------
I appreciate any advice on how to solve this. I have tried so many different things and none come close to what I want.

Javascript Mental Jumpstart : <p>I need some help on a assignment for school, and I'm kinda stuck. This question defines the ones following and I need a mental "jumpstart;" I can't seem to remember what to do to begin.</p>

Angular2 : render a component without its wrapping tag : <p>I am struggling to find a way to do this. In a parent component, the template describes a <code>table</code> and its <code>thead</code> element, but delegates rendering the <code>tbody</code> to another component, like this:</p>
<pre><code><table>
<thead>
<tr>
<th>Name</th>
<th>Time</th>
</tr>
</thead>
<tbody *ngFor="let entry of getEntries()">
<my-result [entry]="entry"></my-result>
</tbody>
</table>
</code></pre>
<p>Each myResult component renders its own <code>tr</code> tag, basically like so:</p>
<pre><code><tr>
<td>{{ entry.name }}</td>
<td>{{ entry.time }}</td>
</tr>
</code></pre>
<p>The reason I'm not putting this directly in the parent component (avoiding the need for a myResult component) is that the myResult component is actually more complicated than shown here, so I want to put its behaviour in a separate component and file.</p>
<p>The resulting DOM looks bad. I believe this is because it is invalid, as <code>tbody</code> can only contain <code>tr</code> elements <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/tbody" rel="noreferrer">(see MDN)</a>, but my generated (simplified) DOM is :</p>
<pre><code><table>
<thead>
<tr>
<th>Name</th>
<th>Time</th>
</tr>
</thead>
<tbody>
<my-result>
<tr>
<td>Bob</td>
<td>128</td>
</tr>
</my-result>
</tbody>
<tbody>
<my-result>
<tr>
<td>Lisa</td>
<td>333</td>
</tr>
</my-result>
</tbody>
</table>
</code></pre>
<p>Is there any way we can get the same thing rendered, but without the wrapping <code><my-result></code> tag, and while still using a component to be sole responsible for rendering a table row ?</p>
<p>I have looked at <code>ng-content</code>, <code>DynamicComponentLoader</code>, the <code>ViewContainerRef</code>, but they don't seem to provide a solution to this as far as I can see.</p>

C++ Hermite interpolation : <p>I found c++ source calculating "Hermite polynomial interpolating function and derivative values".

Redux and within a reducer accessing a different reducer, how? : <p>So, I have an app that has multiple reducers, and thus multiple action creators associated.</p>
<p>There is a time in which one of my reducers updates the state (because of an edit), and as such, I have to then make sure the other reducers see this update and adjust their state accordingly. </p>
<p>think of it as if a user selects "sneakers", and this state management is in a reducer called productsReducer. As such, as a user moves thru the app process, they get couponsReducer associated with it... but the user can "edit" at any time, so if they then edit "sneakers" and say, choose another producer, I have to be able to alter the couponsReducer in real time, because a progress modal needs to reflect this. I can do this via going thru the flow to the coupon page, because on that page I just reconcile the data on componentWillMount... but the rub is I have a progress modal, and prior to getting to the coupons page, a user can open the progress modal... and there will be a missmatch here...</p>
<p>long winded I know, I just wanted to explain my situation.</p>
<p>so, I want to be able to call "other reducers" or their action creators from within the productsReducer. </p>
<p>Would a middleware be appropriate here, in which I sniff for a certain "action.type" and if I see it, I can dispatch other action.type's or is there a way to call action creators from within the productsReducer?</p>
<p>importing: import * as coupons from './couponsActions' and any other actions I need seem inappropriate.</p>

I used
MovieContainer cnt=new Gson().fromJson(jstring, MovieContainer.class);

Client-side request encryption with React : <p>I want to make calls to my backend service in such a way that prevents people from copying the requests from the network tab, and duplicating them using curl, allowing them to burn through my API limits.</p>
<p>My site uses client-side React, so it seems to me that whenever I access the secret key to encrypt the data I'm sending, a user could just set a breakpoint in the Sources folder, and sniff the password I'm using for encryption.</p>
<p>Is there a technology or pattern I'm missing that would solve this problem?</p>
<p>Thanks very much!</p>

Jquery Ajax - Use event within an ajax callback function : <p>Any clues, how I would get this to work?</p>
<pre><code>$( "#search_form" ).on('submit',function(event) {
ajax(function(response){
if (response.status == 'error'){
event.preventDefault();
alert(response.status,response.msg);
}else if(response.status == 'ok'){
alert(response.status,response.msg);
}
});
});
</code></pre>
<p>event.preventDefault(); is not being called, probably because it's out of scope in the ajax function.
This line simply prevents the button from carrying out a post action.
How would i insert it into the ajax function? I'm just learning about callbacks and this has thrown me</p>
<p>Thanks y'all</p>

Differences between Fprint/Fprintf vs conn.Write in GOLANG : Trying to send encrypted data across a TCP connection. Fprintf works fine for unencrypted data but seems to be adding formatting to encrypted data causing the decrypt to fail intermittently. I am unable send using conn.Write or for that matter writer.Writestring followed by writer.Flush().
scanner := bufio.NewScanner(os.Stdin)
for scanner.Scan() && err == nil {
msg := scanner.Text()
ciphertext := md5.Encrypt([]byte(msg+"\n")
conn.Write(append(ciphertext, '\r'))
}
//Receiver
scanner := bufio.NewScanner(conn)
for scanner.Scan() {
ciphertext := scanner.Bytes()
plaintext := md5.Decrypt(ciphertext)
fmt.Println(string(plaintext))
}
Suggestions welcome.

Python2.7: new list from from a single column of existing list : Existing LIST columns: list
Index([u'id', u'last_checkin', u'name'], dtype='object')
New List: zlist
for i in list:
zhostname = i.get('name')
#print zhostname
if zhostname not in zlist:
zlist.append(i)
In 1st list there are multiple entries for the same host with a different last_checkin date. For the new list I am trying add to the list when hostname does not already exist. But the new list seems to be an exact copy of the first list. It is like it is not checking for only the host name in the new list. I do not care about the last_checkin date for either entry.
How does it validate the entry if I am only checking the name of the host?
i.e [if zhostname not in zlist:
zlist.append(i)]
So when it looks for the hostname in zlist is it also validating the other columns and sees it is different based on the whole row?
Hopefully this is not clear as mud. | 0debug |

Creating a new instance of a KClass : <p>I have a Kotlin class whose primary (and only) constructor is empty.</p>

<p>How do I create an instance of this class using reflection?</p>

High CPU and RAM usage, how to know what is the cause? : <p>I am maintaining a cloud server (ubuntu 14, webuzo) on Amazon (AWS).
Recently the usage of CPU and RAM are increasing high which cause the server going down.</p>
<p>i thought there is an attact to the server, then i try to modify the security from the AWS console. I block all the ports, except for accessing the control panel of my hosting panel which i set it to only accept from my ip address.</p>
<p>But still, the CPU and RAM usage is still high.</p>
<p>I guess this is not caused from the outside(attact/flood), but it comes from inside the server.</p>
<p>So the question is how to know or determine what is the cause?</p>

Understanding SQL in depth : <p>at first i want to say sorry for the bad gramar, i dont speak or write in english with regularity.
But here is the purpose of the question ,</p>
<p>Im a newbie programer currently working in a company that develops heavy data-base oriented products, and due to these reasons im currently working on my knowledge to achieve more results and grow inside of the company and also get more close to achieve the excellence while coding.
Most of my work actually focus on import some data from a data-base to another, having to treat these datas so it can fit the data base that will get the data.
Since it normaly have a lot of rows and even archives data-bases that does requires very efficient query's to not lose any time , more and more often im seeing myself in a situation that i require more knowledge.</p>
<p>Few weeks ago i started to understand a little more of how SQL works, and it does took off that beginner feelings of CRUD being a static sentence, specially after i started to put subquerys on the FROM and making some functions inside of select and prepared statements BUT STILL, it lacks of something to give the true enlightment to the coding art to understand NOT how it is writen but how and why it works .</p>
<p>Its a very complicated question even for who asks and i cant even imagine how it is for who answers .
If there is someone that understood my point of view and has pacience to answer this , i really believe that it will help a lot of peoples that got inside of SQL programing.
Thank you.</p>

Pipenv: Command Not Found : <p>I'm new to Python development and attempting to use pipenv. I ran the command <code>pip install pipenv</code>, which ran successfully:</p>

<p>However, when I run the command <code>pipenv install</code> in a fresh root project directory I receive the following message: <code>-bash: pipenv: command not found</code>.

Bash function argument parsing/regex : I want to have a function I can call from the command line that takes the following:
$ command_name /some/path/file.java
and turns into the following call:
command /some/path:file
So basically the part I'm having trouble with is substituting a ':' for the last '/' and stripping the file extension. | 0debug |

Python - Repeat counter when index ends : Simple question - i want a loop that counts up and returns to 0 when it reaches a certain number.
tried something like
while i < 7:
i += 1
if i == 7
i -= 1 #(or change i in any other way - you get the idea)
My Python actually crashed when i tried the above. | 0debug |
Regex to accept any 3 combinations is must but no space : I wanted to allow regex to accept minimum of 8 characters and any 3 combinations out of following 4 categories.
1. One uppercase alpha character
2. One lowercase alpha character
3. One numeric character
4. One special character
The good thing is, there are many regex available for my requirement but most of them allows **space**. I got this [Regex][1] from
[here][2]. I tried to modify this in several ways but I couldn't succeed in writing a proper regex to validate a space along with 3 combinations as i mentioned above.

Returning ES6 Proxy from the ES6 class constructor : <p>I want user to only set specific properties to an object but as the same time that object should be constructed from custom class.</p>
<p>For example</p>
<pre><code>var row = new Row({
name : 'John Doe',
email : 'uhiwarale@gmail.com'
}, Schema);
</code></pre>
<p><code>row</code> can have methods. But when user is trying to set <code>row.password</code>, they are not allowed.</p>
<p>One way to do it is using <code>new Proxy</code> instead of <code>new Row</code> but then we will loose all cool things we are doing inside <code>Row</code> class. I want <code>new Row</code> to return a proxy object with <code>this</code> reference as a target of proxy.</p>
<p>Anybody have any ideas on this? If you know <code>mongoose</code>, how <code>mongoose</code> is doing it?</p>

Getting the same subplot size using matplotlib imshow and scatter : <p>I am trying to plot an image (using <code>matplotlib.imshow</code>) and a scatter plot within the same figure. When trying this, the image appears smaller than the scatter plot. Small example code is shown below:</p>
<pre><code>import matplotlib.pyplot as plt
import numpy as np
image = np.random.randint(100,200,(200,200))
x = np.arange(0,10,0.1)
y = np.sin(x)
fig, (ax1, ax2) = plt.subplots(1,2)
ax1.imshow(image)
ax2.scatter(x,y)
plt.show()
</code></pre>
<p>Which gives the following figure:</p>
<p><a href="https://i.stack.imgur.com/zkHti.png" rel="noreferrer"><img src="https://i.stack.imgur.com/zkHti.png" alt="enter image description here"></a></p>
<p>How can I get the two sublpots to have the same height? (and width I suppose)</p>
<p>I have tried using <a href="http://matplotlib.org/users/gridspec.html" rel="noreferrer"><code>gridspec</code></a> as shown in <a href="https://stackoverflow.com/questions/10388462/matplotlib-different-size-subplots">this</a> answer:</p>
<pre><code>fig=plt.figure()
gs=GridSpec(1,2)
ax1=fig.add_subplot(gs[0,0])
ax2=fig.add_subplot(gs[0,1])
ax1.imshow(image)
ax2.scatter(x,y)
</code></pre>
<p>But this gives the same result. I have also tried to adjust the subplot sizes manually by using:</p>
<pre><code>fig = plt.figure()
ax1 = plt.axes([0.05,0.05,0.45,0.9])
ax2 = plt.axes([0.55,0.19,0.45,0.62])
ax1.imshow(image)
ax2.scatter(x,y)
</code></pre>
<p>By trial and error I can get the two subplots to the correct size, though any change in the overall figure size will mean that the subplots will no longer be the same size.</p>
<p>Is there a way to make <code>imshow</code> and a <code>scatter</code> plot appear the same size in a figure without manually changing the axes sizes?</p>
<p>I am using Python 2.7 and matplotlib 2.0.0</p>

How to use native android webview in Qt C++ using QAndroidJniObject : <p>I would like to use the Android WebView in my qml application. The default WebView object provided uses native rendering but several features are missing (for example the ability to intercept network requests and block them). I know that Qt allows you to call native Java API using QAndroidJniObject. Is it possible to use that to create a Qt wrapper around the native Android WebView? If yes, how can I achieve that? </p>

C++ Functions with struct and vectors : <p>I just finished a program that reads a CSV file and outputs the rows using structs and vectors. My question involves these specific lines:</p>
<pre><code>displayBid(bids[i]);
void displayBid(Bid bid)
{
cout << bid.title << " | " << bid.amount << " | " << bid.fund << endl;
return;
}
</code></pre>
<p>I am not sure if I am thinking about this correctly, but how is displayBid able to take in a vector as a parameter? The displayBid function takes in a struct called of Bid type. Originally I could not get the code to compile because I was trying displayBid(bid) and I got a scope error. I figured the displayBid function would need to take in a struct instead of a vector.

Optimal way to cover a complete are making searching by zipcoe : I want to make a search by zip code, which is defined by polygons like in the picture below:
[![enter image description here][1]][1]
The thing is that actually, I can not make the search on the zip codes itself but in an area from the centroid of that zip code, for example for the zipcode 4, this area touch 1,2 and 5 as well.
[![enter image description here][2]][2]
In the same way, the search for 1 with take the results from 2,3,4 and 6 as well.
Hence to avoid getting duplicates I want to take find out with are the zipcodes with whch I can get all the results with the less number of searches, say take 4, and 6
[![enter image description here][3]][3]
[![enter image description here][4]][4]
Instead of 2,5 and 6
[![enter image description here][5]][5]
How can I approach this problem?

}
}
</code></pre>
<p>But I'm not seeing an icon in the DOM. Although I do see in the Chrome Dev Tools:</p>
<pre><code><span style="text-shadow:0 1px 0 rgba(0, 0, 0, 0.1);" aria-hidden="true" class="fa fa-rocket fa-2x fa-spin super-crazy-colors" data-reactid=".0.$/=11.0.0.$/=10.$/=10.$/=10"></span>
</code></pre>
<p>which I feel like should be a <code><i></code> tag. I tried changing the <code><span>...</span></code> to an <code><i>...</i></code> in "edit as HTML" in the dev tools and the icon still didn't show.</p>
<p>I have add-module-exports in my plugins and stage-2 in my presets in my webpack.config.</p>
<p>Can anyone tell me if I'm missing something? Do I need some other package other than react-fontawesome to make this work? Do I need to import the standard font-awesome.css or load a font-awesome CDN? Any help would be greatly appreciated, thanks!</p>

How do I use Docker environment variable in ENTRYPOINT array? : <p>If I set an environment variable, say <code>ENV ADDRESSEE=world</code>, and I want to use it in the entry point script concatenated into a fixed string like:</p>
<pre><code>ENTRYPOINT ["./greeting", "--message", "Hello, world!"]
</code></pre>
<p>with <code>world</code> being the value of the environment varible, how do I do it? I tried using <code>"Hello, $ADDRESSEE"</code> but that doesn't seem to work, as it takes the <code>$ADDRESSEE</code> literally.</p>
