Javascript Array operations on string-index array : <p>It seems like <code>map</code>, <code>forEach</code>, <code>filter</code> and this sort of operators don't work with string-indexed arrays like so:</p>
<pre><code>let a = [];
a['first element'] = 1;
a['second element'] = 2;
a['third element'] = 3;
a.forEach(console.log)
//undefined

C# SQL SERVER CONVERTING DATE TIME ERROR WHEN TRANSFERING TO ANOTHER PC : I am using VS2012 and SQL SERVER 2012 as database it all works good but when i transfer it to another laptop which also using VS2012 and SQL SERVER 2012 i am having an error in converting date in data base to date time here is the code.
DateTime date = DateTime.Parse(dr8["Date Added"].toString());
The Date Added is in VARCHAR(MAX) but it works well in my pc but when transfered to my laptop it shows String was not recognized as a valid DateTime[enter image description here][1]

Dynamic Zero-Length Arrays in C++ : <pre><code>#include <stdlib.h>
void *operator new[](size_t size, int n){
if( size != 0 && n != 0 )
return calloc(n, size);
return calloc(1, 1);
}
int main(){
int * p1;
const int i = 0;
// p1 = new (20) int[i] ; // Case 1 (OK)
p1 = new (20) (int[i]); // Case 2 (Warning)
if( p1 == 0 )
return 1;
return 0;
}
</code></pre>
<p>This code (<a href="https://godbolt.org/g/hjo7Xn" rel="noreferrer">https://godbolt.org/g/hjo7Xn</a>) compiles successfully with Clang 6.0.0, however, GCC 7.3 issues a warning saying that zero-length arrays are forbidden in C++. If the parentheses are removed (Case 1), the warning goes away. </p>
<p>Unlike statically allocated zero-length arrays (C++03:8.3.4/1), dynamically allocated zero-length arrays are allowed (C++03:5.3.4/6). Nevertheless, in the C++ Standard the latter are explicitly allowed only when following one of the two possible syntax paths of the <em>new-expression</em>, that is, the one with <em>new-type-id</em> and without parentheses (Case 1). </p>
<p><strong>Is it allowed by the C++ Standard to use the <em>new-expression</em> with a zero-length array following the second syntax path, that is, with <em>type-id</em> and parentheses (Case 2)?</strong></p>
<p>The only related quote is C++03:5.3.4/5:</p>
<blockquote>
<p>When the allocated object is an array (that is, the <em>direct-new-declarator</em> syntax is used or the <em>new-type-id</em> or <em>type-id</em> denotes an array type), the <em>new-expression</em> yields a pointer to the initial element (if any) of the array.</p>
</blockquote>
<p>The wording <code>(if any)</code> would allow an array with no elements, however, it does not seem clear if it refers to both cases or only to the one with <em>new-type-id</em> and without parentheses (Case 1).</p>
<p>Thanks in advance.</p>
<p>Notes:</p>
<ol>
<li>ISO/IEC 14882:2003, Section 8.3.4, Paragraph 1:
<blockquote>
<p>If the <em>constant-expression</em> (5.19) is present, it shall be an integral constant expression and its value shall be greater than zero.</p>
</blockquote></li>
<li>ISO/IEC 14882:2003, Section 5.3.4, Paragraph 6:
<blockquote>
<p>The <em>expression</em> in a <em>direct-new-declarator</em> shall have integral or enumeration type (3.9.1) with a non-negative value.</p>
</blockquote></li>
<li>ISO/IEC 14882:2003, Section 5.3.4, Paragraph 7:
<blockquote>
<p>When the value of the <em>expression</em> in a <em>direct-new-declarator</em> is zero, the allocation function is called to allocate an array with no elements.</p>
</blockquote></li>
<li>ISO/IEC 14882:2003, Section 5.3.4, Paragraph 1:
<blockquote>
<p><em>new-expression</em>:</p>
<p>::<code>opt</code> <strong>new</strong> <em>new-placement</em><code>opt</code> <em>new-type-id</em> <em>new-initializer</em><code>opt</code></p>
<p>::<code>opt</code> <strong>new</strong> <em>new-placement</em><code>opt</code> ( <em>type-id</em> ) <em>new-initializer</em><code>opt</code></p>
</blockquote></li>
<li>Although the above quotes are from the C++03 Standard, to the best of my knowledge this issue is still unclear in newer versions of the C++ Standard (C++11, C++14 and C++17).</li>
<li>Interesting Herb Sutter's <a href="https://herbsutter.com/2009/09/02/when-is-a-zero-length-array-okay/" rel="noreferrer">post</a> about zero-length arrays.</li>
<li>The code in the example is a slightly modified test from <a href="https://www.solidsands.nl" rel="noreferrer">SolidSands'</a> SuperTest suite.</li>

what does `yield from asyncio.sleep(delay)` do? : <p>The following example from Python in a Nutshell sets <code>x</code> to <code>23</code> after a delay of a second and a half:</p>
<pre><code>@asyncio.coroutine
def delayed_result(delay, result):
yield from asyncio.sleep(delay)
return result
loop = asyncio.get_event_loop()
x = loop.run_until_complete(delayed_result(1.5, 23))
</code></pre>
<p>I feel difficult to understand what <code>yield from asyncio.sleep(delay)</code> does.</p>
<p>From <a href="https://docs.python.org/3/library/asyncio-task.html#asyncio.sleep" rel="noreferrer">https://docs.python.org/3/library/asyncio-task.html#asyncio.sleep</a></p>
<blockquote>
<pre><code>Coroutine asyncio.sleep(delay, result=None, *, loop=None)
</code></pre>
<p>Create a coroutine that completes after a given time (in seconds). If
result is provided, it is produced to the caller when the coroutine
completes.</p>
</blockquote>
<p>So <code>asyncio.sleep(delay)</code> returns a coroutine object.</p>
<p>What does a coroutine object "completes" mean?</p>
<p>What values does <code>yield from asyncio.sleep(delay)</code> provide to the main program?</p>
<p>Thanks.</p>

How to get front camera, back camera and audio with AVCaptureDeviceDiscoverySession : <p>Before iOS 10 came out I was using the following code to get the video and audio capture for my video recorder:</p>
<pre><code> for device in AVCaptureDevice.devices()
{
if (device as AnyObject).hasMediaType( AVMediaTypeAudio )
{
self.audioCapture = device as? AVCaptureDevice
}
else if (device as AnyObject).hasMediaType( AVMediaTypeVideo )
{
if (device as AnyObject).position == AVCaptureDevicePosition.back
{
self.backCameraVideoCapture = device as? AVCaptureDevice
}
else
{
self.frontCameraVideoCapture = device as? AVCaptureDevice
}
}
}
</code></pre>
<p>When iOS 10 finally came out, I received the following warning when I was running my code. Note that my video recorder was still working smoothly for about 2 weeks.</p>
<blockquote>
<p>'devices()' was deprecated in iOS 10.0: Use AVCaptureDeviceDiscoverySession instead.</p>
</blockquote>
<p>As I was running my code this morning, my video recorder stopped working. xCode8 does not give me any errors but the previewLayer for the camera capture is completely white. When I then start recording I receive the following error:</p>
<blockquote>
<p>Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x17554440 {Error Domain=NSOSStatusErrorDomain Code=-12780 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-12780)}</p>
</blockquote>
<p>I believe that has something to do with the fact that I am using the deprecated approach <code>AVCaptureDevice.devices()</code>. Hence, I was wondering how to use <code>AVCaptureDeviceDiscoverySession</code> instead?</p>
<p>Thank you for your help in advance!</p>

Spark on Amazon EMR: "Timeout waiting for connection from pool" : <p>I'm running a Spark job on a small three server Amazon EMR 5 (Spark 2.0) cluster. My job runs for an hour or so, fails with the error below. I can manually restart and it works, processes more data, and eventually fails again.</p>
<p>My Spark code is fairly simple and is not using any Amazon or S3 APIs directly. My Spark code passes S3 text string paths to Spark and Spark uses S3 internally.</p>
<p>My Spark program just does the following in a loop: Load data from S3 -> Process -> Write data to different location on S3. </p>
<p>My first suspicion is that some internal Amazon or Spark code is not properly disposing of connections and the connection pool becomes exhausted.</p>

Could someone help me out with this SQL query? : I am asked this:
> Use a subquery in the FROM clause to only retrieve invoices from
> chamber 'H' and the invoice amount of larger than 10000 and join the
> result with the voyages table using the number column. Project to only
> retrieve the boatname and the invoice amount of the join result. Order
> by invoice amount.
So, I made this:
SELECT chamber=(SELECT chamber FROM invoices INNER JOIN voyages ON chambers.chamber='H' AND chambers.invoice > 10000 AND invoice.number=voyages.number), boatname, invoice FROM chambers, voyages, invoices WHERE chambers.chamber=invoices.chamber, invoices.number=voyages.number
*This is the chambers table:*
# chamber name
1 A New York
*This is the invoices table:*
# number invoice chamber
1 8300 9189 A
Yet it keeps giving me this error: `Query failed: near ",": syntax error`
I can't solve it. Could someone help me out?

How to access host component from directive? : <p>Say I have the following markup:</p>
<pre><code><my-comp myDirective></my-comp>
</code></pre>
<p>Is there any way I can access the component instance <strong>from the directive</strong>?</p>
<p>More specifically I want to be able to access the properties and methods of <code>MyComponent</code> from <code>MyDirective</code>, ideally <strong>without adding anything to the HTML above</strong>.</p>

git submodule init does absolutely nothing : <p>I have a strange problem with "git submodule init"</p>
<p>When I added the submodules using "git submodule add url location" it cloned the repository just fine and everything was ok.</p>
<p>When I pushed all my changes back to the parent repository, added the .gitmodules files, etc and cloned the repository back, I tried to initialise all the submodules using "git submodule init" </p>
<p>And nothing happens :( Literally nothing, no output, no extra files, it does not even attempt to do anything actually.</p>
<p>So I am wondering, what did I do wrong?</p>
<p>.gitmodules:</p>
<pre><code>bash$ cat .gitmodules
[submodule "projects/subprojectA"]
path = projects/subprojectA
url = ssh://user@bitbucket.company.com/test/projectA.git
[submodule "projects/subprojectB"]
path = projects/subprojectB
url = ssh://user@bitbucket.company.com/test/projectB.git

[Gitlab]Where can I find Gitlab Pages hosted on my private Gitlab instance? : <p>I tried to set up Gitlab Pages, until now I finished uploading my static website files👇</p>

Uploading artifacts to coordinator... ok id=1038 responseStatus=201 Created token=QXJjgkf2
</code></pre>
<p>But I got no idea where my page hosted.</p>
<p>I took a glance at <a href="https://docs.gitlab.com/ce/user/project/pages/getting_started_part_one.html#practical-examples" rel="noreferrer">this documentation</a> but it was still vague to me.</p>
<ul>
<li>I have a private Gitlab instance.</li>
<li>My Gitlab entry is under <a href="http://abc.def.com" rel="noreferrer">http://abc.def.com</a> (I configured a type A DNS to my host IP 111.111.111.111, a reverse proxy pointing at localhost:9000).</li>
<li>My project <code>project1</code> is under my team <code>team1</code>.</li>
<li>I have also configured DNS <a href="http://team1.abc.def.com" rel="noreferrer">http://team1.abc.def.com</a> to 111.111.111.111 , and there is a nginx reverse proxy on my server which <a href="http://team1.abc.def.com" rel="noreferrer">http://team1.abc.def.com</a> -> localhost:9000.</li>
</ul>
<p>I assume I should see my static page available on <a href="http://team1.abc.def.com/project1" rel="noreferrer">http://team1.abc.def.com/project1</a> , but nothing was there. Where exactly are my pages hosted?</p>

Why Java 8 Stream interface does not have min() no-parameter version? : <p><code>java.util.stream.Stream</code> interface has two versions of <code>sorted</code> method – <code>sorted()</code> which sorts elements in natural order and <code>sorted(Comparator)</code>. Why <code>min()</code> method was not introduced to <code>Stream</code> interface, which would return minimal element from natural-ordering point of view?</p>

How to add a request interceptor to a feign client? : <p>I want every time when I make a request through feign client, to set a specific header with my authenticated user. </p>

Need to parse the data from Json file using python script : I created the json from a python script, and here is the code what I wrote to get the json data:
import requests
import json
import ConfigParser
url = "xxx"
payload = "items.find({ \"repo\": {\"$match\" : \"nswps-*\"}}).include(\"name\",\"repo\",\"path\")\r\n"
headers = {
'Content-Type': "text/plain",
'Authorization': "Basic xxxxxxxxx",
'Accept': "*/*",
'Cache-Control': "no-cache",
'Host': "xxxxxx.com",
'accept-encoding': "gzip, deflate",
'content-length': "77",
'Connection': "keep-alive",
'cache-control': "no-cache"
}
response = requests.request("POST", url, data=payload, headers=headers)
print(response.text)
the above code gives me the json file which is a huge file of multiple objects. Due to some limitation in artifactory I am unable to get the repos starting with nswps but rather the result is all the repository names. The json file has data like this:
"repo" : "npm-remote-cache",
"path" : "zrender/-",
"name" : "zrender-4.0.7.tgz"
},{
"repo" : "npm-remote-cache",
"path" : "ztree/-",
"name" : "ztree-3.5.24.tgz"
},{
"repo" : "nswps-docker-inprogress-local",
"path" : "ace/core/latest",
"name" : "manifest.json"
},{
"repo" : "nswps-docker-inprogress-local",
"path" : "ace/core/latest",
"name" : "sha256__0a381222a179dbaef7d1f50914549a84e922162a772ca5346b5f6147d0e5aab4"
},{
.........
Now I need to create a python script which fetches out the objects in which only the object that has value of nswps , lets say from the above json I need data like this:
{
"repo" : "nswps-docker-inprogress-local",
"path" : "ace/core/latest",
"name" : "manifest.json"
},{
"repo" : "nswps-docker-inprogress-local",
"path" : "ace/core/latest",
"name" : "sha256__0a381222a179dbaef7d1f50914549a84e922162a772ca5346b5f6147d0e5aab4"
}
Please suggest!

How can I call a class method inside a promise in Angular 2? : <p>If I have an Angular 2 component and I get data from a service that returns an async promise or observable how can I then call a method in the component to display that data?</p>
<pre><code>@Component({
moduleId: module.id,
selector: 'charts',
templateUrl: 'charts.component.html',
providers: [DataService]
})
export class ChartsComponent implements OnInit {
constructor(private dataService:DataService)
ngOnInit() {
this.getData();
}
getData(){
this.dataService.getData().then(function (data) {
this.drawChart(data);
});
}
drawChart(){
//implement drawing chart
}
}
</code></pre>
<p>The problem is that inside a promise "this" in "this.drawChart()" no longer refers to the ChartsComponent class. How can I call a class method post promise?</p>
<p>Also, I cant put drawChart() inside the promise because it needs to use other class properties.</p>

What is the job of autogen.sh when building a c++ package on Linux : <p>I saw a common pattern when installing a c/c++ package from source on Linux (Ubuntu 16.04):</p>
<ol>
<li>./autogen.sh</li>
<li>./configure</li>
<li>make</li>
<li>make install</li>
</ol>
<p>I understand <code>make</code> and <code>make install</code>, and I guess <code>configure</code> creates a Makefile based on user preferences, but I don't see why <code>autogen.sh</code> is necessary. </p>
<p>Does anyone know what it is there for?</p>

Implement Relu derivative in python numpy : <p>I'm trying to implement a function that computes the Relu derivative for each element in a matrix, and then return the result in a matrix. I'm using Python and Numpy.</p>
<p>Based on other Cross Validation posts, the Relu derivative for x is
1 when x > 0, 0 when x < 0, undefined or 0 when x == 0</p>
<p>Currently, I have the following code so far:</p>
<pre><code>def reluDerivative(self, x):
return np.array([self.reluDerivativeSingleElement(xi) for xi in x])
def reluDerivativeSingleElement(self, xi):
if xi > 0:
return 1
elif xi <= 0:
return 0
</code></pre>
<p>Unfortunately, xi is an array because x is an matrix. reluDerivativeSingleElement function doesn't work on array. So I'm wondering is there a way to map values in a matrix to another matrix using numpy, like the exp function in numpy?</p>
<p>Thanks a lot in advance.</p>

How to update service worker cache in PWA? : <p>I use service worker with <a href="https://github.com/GoogleChrome/sw-toolbox" rel="noreferrer">sw-toolbox</a> library. My PWA caches everything except API queries (images, css, js, html). But what if some files will be changed someday. Or what if service-worker.js will be changed.
How application should know about changes in files?</p>
<p>My service-worker.js:</p>
<pre><code>'use strict';
importScripts('./build/sw-toolbox.js');
self.toolbox.options.cache = {
name: 'ionic-cache'
};
// pre-cache our key assets
self.toolbox.precache(
[
'./build/main.js',
'./build/main.css',
'./build/polyfills.js',
'index.html',
'manifest.json'
]
);
// dynamically cache any other local assets
self.toolbox.router.any('/*', self.toolbox.cacheFirst);
// for any other requests go to the network, cache,
// and then only use that cached resource if your user goes offline
self.toolbox.router.default = self.toolbox.networkFirst;
</code></pre>
<p>I don't know what is the usual method to update cache in PWA. Maybe PWA should send AJAX request in background and check UI version?</p>

constraint satisfaction problem missing one constraint : <p>I'm a lab practises tutor at the university, based on last year student comments, we wanted, my boss and I, to address them.

<li>There are 4 roles</li>
<li>There are 6 practices</li>
<li>There are 32 students</li>
<li>There are 4 students per team</li>

<h2>Problem :</h2>
<p>Assign each student to 4 roles, in 4 practices in 4 different sessions. </p>
<h2>Constraints :</h2>
<ol>
<li>Students should do a role once </li>
<li>Students should do 4 different practices out of 6</li>
<li>Students should do only one practice per session</li>
<li><strong>Student should meet the same mate only once</strong></li>

<h2>What I have so far :</h2>
<p>Using <a href="http://labix.org/doc/constraint/" rel="noreferrer">python-constraint</a> I was able to validate the first three constraints : </p>
<pre class="lang-py prettyprint-override"><code>Valid solution : False
- sessions : [True, True, True, True, True, True]
- practices : [True, True, True, True, True, True]
- roles : [True, True, True, True]
- teams : [False, False, True, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, True, False, False, False, False, False]
</code></pre>
<h3>For those that may interesting I simply do like this :</h3>
<p>For each condition I use <a href="http://labix.org/doc/constraint/" rel="noreferrer">AllDifferentConstraint</a>. For example, for one session I do: </p>
<pre class="lang-py prettyprint-override"><code>problem.addConstraint(AllDifferentConstraint(), [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24])
</code></pre>
<p>I'm not able to find a way to constraint team, my last attempt on the entire <code>semester</code> was this : </p>
<pre class="lang-py prettyprint-override"><code> def team_constraint(self, *semester):
students = defaultdict(list)
# get back each teams based on the format [# Semester [ #Session [# Practice/Team ...
teams = [list(semester[i:i+4]) for i in range(0, len(semester), 4)]
# Update Students dict with all mate they work with
for team in teams:
for student in team:
students[student] += [s for s in team if s != student]
# Compute for each student if they meet someone more than once
dupli = []
for student, mate in students.items():
dupli.append(len(mate) - len(set(mate)))
# Loosly constraint, if a student meet somone 0 or one time it's find
if max(dupli) >= 2:
print("Mate encounter more than one time", dupli, min(dupli) ,max(dupli))
return False
pprint(students)
return True
</code></pre>
<h1>Questions :</h1>
<ol>
<li>Is it possible to do what I want for the team conditions ? What I mean is I have no idea if it is possible to assign 12 mates to each student and each of them meet the same mate only once.</li>
<li>For the team constraint, did I miss a more performant algorithm ? </li>
<li>Any pist that I can follow ? </li>
</ol>

How to convert a string to an integer in a JSON file using jq? : <p>I use jq to transform a complex json object into a tinier one. My query is:</p>
<pre><code>jq 'to_entries[]| {companyId: (.key), companyTitle: (.value.title), companyCode: (.value.booking_service_code)}' companies.json
</code></pre>
<p>Now, the <code>(.key)</code> is parsed as a string, yet I want <code>companyId</code> to be a number.</p>
<p>My result currently looks like this:</p>
<pre><code>{
"companyId": "1337",
"companyTitle": "Some company title",
"companyCode": "oxo"
}
</code></pre>
<p>yet it should be like:</p>
<pre><code>{
"companyId": 1337,
"companyTitle": "Some company title",
"companyCode": "oxo"

Avoid const locals that are returned? : <p>I always thought that it's good to have const locals be const</p>
<pre><code>void f() {
const resource_ptr p = get();
// ...
}
</code></pre>
<p>However last week I watched students that worked on a C++ exercise and that wondered about a const pointer being returned</p>
<pre><code>resource_ptr f() {
const resource_ptr p = get();
// ...
return p;
}
</code></pre>
<p>Here, if the compiler can't apply NRVO (imagine some scenario under which that is true, perhaps returning one of two pointers, depending on a condition), suddenly the <code>const</code> becomes a pessimization because the compiler can't move from <code>p</code>, because it's const. </p>
<p>Is it a good idea to try and avoid <code>const</code> on returned locals, or is there a better way to deal with this?</p>

In Django 1.9, what's the convention for using JSONField (native postgres jsonb)? : <p>Django <a href="https://docs.djangoproject.com/en/1.9/ref/models/fields/#null">highly suggests</a> <strong>not</strong> to use <code>null=True</code> for CharField and TextField string-based fields in order not to have two possible values for "no data" (assuming you're allowing empty strings with <code>blank=True</code>). This makes total sense to me and I do this in all my projects.</p>
<p>Django 1.9 introduces <a href="https://docs.djangoproject.com/en/1.9/ref/contrib/postgres/fields/#django.contrib.postgres.fields.JSONField">JSONField</a>, which uses the underlying Postgres <code>jsonb</code> data type. Does the suggestion above carry over to JSONField (i.e. <code>blank=True</code> should be used instead of <code>null=True</code>)? Or, should <code>null=True</code> be used instead? Or, should <code>default=dict</code> be used instead? Or, ..? Why?</p>
<p>In other words, what is the convention for the new native JSONField, when you want to allow only one "no data" value? Please support your answer because I did a lot of research and couldn't find anything official. Thanks in advance.</p>

Microsoft GraphQL - has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin : I'm running my Vue app locally from http://localhost:8080 and I keep getting a slew of CORS errors, I've added the Access-Control-Allow-Origin header as seen blow but keep getting the following warning:

I've tried adding mode: 'no-cors' but just get the following - Error: Invalid value for opts.mode
I've also tried '*' as the access control origin but to no avail.
Is there a way through this CORS nightmare as we need to make this call to retrieve a key! Pretty new to all of this so please bare with me if I've not been as descriptive as I could have been!

How to chake if server connection is exist? : In my app I have asyncTask classes, that connect to the local/remote server to get some data, I want to check the server connection before the asyncTask is run,
I got this function:
public static boolean checkServerAvailable(String hostURL)
{
HttpURLConnection connection = null;
try {
URL u = new URL(hostURL);
connection = (HttpURLConnection) u.openConnection();
connection.setConnectTimeout(5000);
connection.setRequestMethod("HEAD");
int code = connection.getResponseCode();
System.out.println("" + code);
return true;
// You can determine on HTTP return code received. 200 is success.
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
} finally {
if (connection != null) {
connection.disconnect();
}
}
}
this function using timeout to connect to server, and if the timeout is finish it's mean that there is no server, the problem is that I'm run this code and it's returning "there is no server" if the server is exist too,
I'm tried to set a big timeout like 5000ms but it's stop the UI very long time, and somtiems return "there is no server" when the server is exist too.
what can I do?
Thank you!

webpack live hot reload for sass : <p>I am building a workflow for a react starter and would like to have my browser auto reload when I make a change to my scss files.</p>
<p>Currently, webpack will hot reload when I make a change in my index.js file (set as my entry point). However when I change/add scss code in my scss file, it gets compiled, but the css doesn't get output anywhere and does not trigger a browser reload. </p>
<p>I am new to webpack would really appreciate some insight here.</p>
<p>Here is my webpack.config.js</p>
<pre><code>const path = require('path');

Azure Table Storage CreateQuery in .NET Core : <p>I'm porting my existing class library that targets .NET Framework 4.6.2 to .NET Core 1.1.</p>
<p>Looks like some of the methods that are available in .NET Framework version are not there in .NET Core. Two such methods are <code>table.CreateQuery</code> and <code>table.ExecuteQuery</code>.</p>
<p>Here's an existing function that's giving me an error for CreateQuery:</p>
<pre><code>public T Get<T>(string partitionKey, string rowKey, string tableName) where T : ITableEntity, new()
=> getTable(tableName).CreateQuery<T>().Where(r => r.PartitionKey == partitionKey && r.RowKey == rowKey).FirstOrDefault();

How can I specify a python version using setuptools? : <p>Is there a way to specify a python version to be used with a python package defined in setup.py? </p>
<p>My setup.py currently looks like this: </p>
<pre><code>from distutils.core import setup
setup(

packages = ['macroetym'], # this must be the same as the name above
version = '0.1',
description = 'A tool for macro-etymological textual analysis.',
author = 'Jonathan Reeve',
author_email = 'jon.reeve@gmail.com',
url = 'https://github.com/JonathanReeve/macro-etym',
download_url = 'https://github.com/JonathanReeve/macro-etym/tarball/0.1', # FIXME: make a git tag and confirm that this link works
install_requires = ['Click', 'nltk', 'pycountry', 'pandas',
'matplotlib'],

</code></pre>
<p>It's a command-line program. My script runs using Python 3, but a lot of operating systems still have Python 2 as the default. How can I specify a python version to be used here? I can't seem to find anything in <a href="https://pythonhosted.org/setuptools/setuptools.html#declaring-dependencies" rel="noreferrer">the docs</a>, but maybe I'm not looking in the right place? </p>

Client doesn't have permission to access the desired data in Firebase : <p>I have a page that is calling <code>addCheckin()</code> method which is inside a controller. In the controller, I am trying to create a reference as follows:</p>
<pre><code>var ref = firebase.database().ref("users/" + $scope.whichuser + "/meetings/" +$scope.whichmeeting + "/checkins");
</code></pre>
<p><code>$scope.whichuser</code> and <code>$scope.whichmeeting</code> are the <code>$routeParams</code> that I am passing from another route.
Here's my checkin controller-</p>
<pre><code>myApp.controller("CheckinsController",
['$scope','$rootScope','$firebaseArray','$routeParams','$firebaseObject',
function($scope,$rootScope,$firebaseArray,$routeParams,$firebaseObject){
$scope.whichuser = $routeParams.uid;
$scope.whichmeeting = $routeParams.mid;
var ref = firebase.database().ref("users/" + $scope.whichuser + "/meetings/" +$scope.whichmeeting + "/checkins");
$scope.addCheckin = function(){
var checkinInfo = $firebaseArray(ref);
var data={
firstname:$scope.firstname,
lastname:$scope.lastname,
email:$scope.email,
date:firebase.database.ServerValue.TIMESTAMP
}
checkinInfo.$add(data);
}
}]);/*controller*/
</code></pre>
<p>There are two errors that I am getting here-</p>
<p>Error 1:</p>
<p><code>Error: permission_denied at /users/Vp2P1MqKm7ckXqV2Uy3OzTnn6bB3/meetings: Client doesn't have permission to access the desired data.</code></p>
<p>Error 2:</p>
<p><code>Error: permission_denied at /users/Vp2P1MqKm7ckXqV2Uy3OzTnn6bB3/meetings/-KT5tqMYKXsFssmcRLm6/checkins: Client doesn't have permission to access the desired data.</code></p>
<p>And this is what I am tring to achieve-</p>
