Electron - Not allowed to load local resource : <p>Evening,<br>
I'm looking into using <a href="http://electron.atom.io/" rel="noreferrer">electron</a> to package an existing angular2 build. I thought I had a dry run working but the actual packaging seems to be failing (see final step below) and I want to understand why. Here's what I'm doing...</p>
<p><strong>Create Project</strong><br>
Use <a href="https://cli.angular.io/" rel="noreferrer">angular-cli</a> to start a new project <code>ng new electron-ng2-cli --style=scss</code></p>
<p>Install electron and <a href="https://github.com/electron-userland/electron-builder" rel="noreferrer">electron-builder</a></p>
<p><strong>Edit package.json</strong><br>Make the following additions...<br>
<code>"main": "main.js"</code></p>
<pre><code>"build":
{
"appId": "com.electrontest.testapp",
"mac": {
"category": "your.app.category.type"
}
}
</code></pre>
<p>and add the following to the <code>scripts</code>...</p>
<pre><code>"pack": "build --dir",
"dist": "build",
"electron": "electron main.js",
"postinstall": "install-app-deps"
</code></pre>
<p><strong>Create main.js</strong><br>I just copied the code from the <a href="https://github.com/electron/electron-quick-start/blob/master/main.js" rel="noreferrer">electron quick start</a>. The only change I make is to the location of <code>index.html</code> which I set to <code>/dist/index.html</code></p>
<p><strong>Amend base</strong><br>In <code>index.html</code> change <code><base="/"></code> to <code><base="./"></code> </p>
<p><strong>Pack code</strong><br>Run <code>ng build</code>. This puts all the packaged code in <code>/dist</code></p>
<p><strong>Test Run</strong><br>Run <code>npm run electron</code>. This works fine. An Electron app fires up and I see the angular stuff running within it.</p>
<p><strong>Create App For Distribution</strong><br>Run <code>npm run pack</code> to create a packaged app. The packaging seems to go ok - I get a warning about a missing icon and a warning that my code is unsigned but I'm guessing they shouldn't be fatal?<br>
The problem is that when I now run the app by double clicking in <code>Finder</code> I get an error in the console saying: <code>Not allowed to load local resource: file:///Users/<username>/Documents/development/electron-ng2-cli/dist/mac/electron-ng2-cli.app/Contents/Resources/app.asar/dist/index.html</code>
<hr>
So, can anyone explain what is different between the packaged app that fails and the one that runs ok when I use <code>npm run electron</code>?</p>
<p>What can I do to fix this issue and get the app running correctly?</p>
<p>Thank you for making it to the end. This got longer than I wanted but I hope I explained myself ok. If you can help or give any pointers that would be great - many good vibes will be thought in your general direction :)</p>
<p>Cheers all</p>

Flutter: How to read preferences at Widget startup? : <p>I have been trying to read preferences at Widget startup but have been unable to find a solution.
I wish to show the users name in a TextField (which they can change) and store it in preferences so that it is shown as soon as they go back to the page.</p>
<pre><code>class _MyHomePageState extends State<MyHomePage> {
TextEditingController _controller;
:
:
Future<Null> storeName(String name) async {
SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setString("name", name);
}
@override
initState() async {
super.initState();
SharedPreferences prefs = await SharedPreferences.getInstance();
_controller = new TextEditingController(text: prefs.getString("name"));
}
@override
Widget build(BuildContext context) {
:
:
return new TextField(
decoration: new InputDecoration(
hintText: "Name (optional)",
),
onChanged: (String str) {
setState(() {
_name = str;
storeName(str);
});
},
controller: _controller,
)
}
}
</code></pre>
<p>I got the idea for using async on initState() from :<br/>
<a href="https://stackoverflow.com/questions/45107702/flutter-timing-problems-on-stateful-widget-after-api-call">flutter timing problems on stateful widget after API call</a> <br/>
But the async seems to cause this error on startup :</p>
<pre><code>'package:flutter/src/widgets/framework.dart': Failed assertion: line 967 pos 12:
'_debugLifecycleState == _StateLifecycle.created': is not true.
</code></pre>
<p>I looked for examples of FutureBuilder but cannot seem to find any which are similar to what I am trying to do.</p>

Using enum instead of struct for tag dispatching in C++ : <p>Let's take implementation of the <code>std::unique_lock</code> from the Standard Library:</p>

struct try_to_lock_t { explicit try_to_lock_t() = default; };
struct adopt_lock_t { explicit adopt_lock_t() = default; };
inline constexpr defer_lock_t defer_lock {};
inline constexpr try_to_lock_t try_to_lock {};
inline constexpr adopt_lock_t adopt_lock {};
unique_lock (mutex_type& m, defer_lock_t t) noexcept;
unique_lock (mutex_type& m, try_to_lock_t t);
unique_lock (mutex_type& m, adopt_lock_t t);
</code></pre>
<p>Is there a reason why one wouldn't/couldn't/shouldn't use enums instead of structs to implement tag dispatching? Such as:</p>
<pre><code>enum defer_lock_t { defer_lock };
enum try_to_lock_t { try_to_lock };
enum adopt_lock_t { adopt_lock };
unique_lock (mutex_type& m, defer_lock_t t) noexcept;
unique_lock (mutex_type& m, try_to_lock_t t);
unique_lock (mutex_type& m, adopt_lock_t t);

<p>The latter is more concise.</p>
<p>The only advantage of using structs that I can think of is inheritance (eg, iterator tags). But in all other cases, why not use enum?</p>

Why use positional only arguments in pythin 3.8 : A new "positional only arguments" syntax has been introduced in 3.8.
> There is new syntax (/) to indicate that some function parameters must
> be specified positionally (i.e., cannot be used as keyword arguments).
> This is the same notation as shown by help() for functions implemented
> in C (produced by Larry Hastings’ “Argument Clinic” tool). Example:
> Now pow(2, 10) and pow(2, 10, 17) are valid calls, but pow(x=2, y=10) and pow(2, 10, z=17) are invalid.
----
My question is, why ever use this syntax?
Why is it better for the code's user?
It seems to me that this makes it harder for users to specify what their arguments actually mean, if they so desire.
Why make it harder on the user?
I am clearly missing something. | 0debug |

<p>But <code>something_const</code> is not dynamic, because it is known at compile time.</p>

JSON Web Token (JWT) : Authorization vs Authentication : <p>JWT terminology has been bothering me for few reasons. Is JWT suitable for Authorization or is it only for Authentication?</p>
<p>Correct me if I'm wrong but I have always read Authorization as being the act of allowing someone access to a resource yet JWT doesn't seem to have any implementation that actually allows access to users to a given resource. All JWT implementations talk about is providing a user a token . This token is then passed with every call to a back-end service endpoint where it is checked for validity and if valid access is granted. So we can use JWT for <strong>Authentication</strong> of any user but how can we restrict the access to particular valid users ?</p>
<p>How can we use JWT for restricting few users depending on roles they have ?
Do JWT provide any type Authorization details as well or it just provide us Authetication ?</p>
<p>Thanks in advance for your help and reading my doubt patiently.</p>

Window.open with 'noopener' opens a new window instead of a new tab : <p>I was using <code>window.open('')</code> with <code>'_blank'</code> as second parameter to open my link in new tab For eg. <code>window.open('http://google.com', '_blank')</code></p>
<p>But, recently I added the third parameter <code>'noopener'</code> so that <code>window.opener</code> becomes null in the new tab and the new tab does not have access to the parent tab/window. i.e. <code>window.opener</code> is <code>null</code></p>
<p><code>window.open('http://google.com', '_blank', 'noopener')</code></p>
<p>So the above code solved the security problem, but instead of opening a new tab, a new window started opening which is not what I expected. My browser settings were same and no changes were made to it.</p>
<p>Is there anything I can do to make this code open new tab instead of new window ? I do not want to remove <code>noopener</code> as third parameter</p>

Hamcrest When to use Is or equalTo : <p>I'm new using hamcrest. While I'm discovering how to use it I have been a doubt about when to use <code>is</code> or <code>equalTo</code>. </p>
<p>Is there any difference between <code>is</code> and <code>equalTo</code>, although it is conceptually or ocasionally? It seems to behave the same. </p>
<pre><code> Assert.assertThat(actual, equalTo("blue"));

2. I want to set `a:1` and `b:3` and so on...
>I want them set in a dictionary called `point_values`.
**How should I do this?**

How to untrack files (git and git GUI) : <p>I am using git GUI (together with Git bash). Now, I know if I want to ignore files for git I have to put them in a .gitignore file. </p>
<p>1)I have come to know that git in windows does not create a .gitignore file for you and you have to create it yourself. Also git GUI won't do that. Is this correct?</p>
<p>Now my special situation:</p>
<p>I made a mistake in the beginning of managing this project and together with my .c and .h files I also tracked another file (let's call it "shouldnottrack.file"). This file is generated by the build process, so in principle should not be tracked. </p>
<p>But I did it and it was included in the commits (staged, commited etc).</p>
<p>Now, I want to <strong>untrack</strong> this file. </p>
<p>I have done it temporalily by doing <code>git checkout -- shouldnottrack.file</code> but this works only once</p>
<p>2) How can I untrack this file? (GUI, command, any method ok)</p>
<p>3) If I include this file in the .gitignore file, will git untrack it automatically?</p>
<p>thanks</p>

file read exception handle : I am getting this error "Exception thrown at 0x0FC04AFF (vcruntime140d.dll) in Ergasia.exe: 0xC0000005: Access violation writing location 0x00000020.
If there is a handler for this exception, the program may be safely continued.".
Which takes me to this part of my code :
for (unsigned int i = 0; i < width*height * 3; i = i + 3) {
file.read((char *)cR, 1);
file.read((char *)cG, 1);
file.read((char *)cB, 1);
buffer[i] = cR / 255.0f;
buffer[i + 1] = cG / 255.0f;
buffer[i + 2] = cB / 255.0f;
}
I tried using try/catch and some other if checks but neither worked. Anyone knows what's causing it? | 0debug |

Avoid concurrency issues with consumer / producer classes : <p>So, I'm building an console application that has a List of objects. </p>
<ul>
<li><p>Every 1000ms, a "producer" is doing a HTTP request and creating a new object from the result, and adds it to the List of objects.</p></li>
<li><p>Every 1000ms, a "consumer" is going analysing through all the objects in the list.</p></li>
<li><p>Every 2000ms, another "consumer" is going analysing through all the objects in the list.</p></li>
<li><p>Every 3500ms, another "consumer" is going analysing through all the objects in the list.</p></li>
</ul>
<p>Once in a while, at arbitrary times, I want to ask one of the consumers what the result of this analysed data is. </p>
<p>So this sounds like a classic producer / consumer pattern. In JavaScript this wouldn't be a problem, since it's nonblocking. But how about C#? I would assume this could be quite a concurrency nightmare. As far as I can understand, this cannot be done simply with Tasks, since you cannot control whether it is running in the same thread context, or a new thread. </p>
<p>I'm looking for the "simplest" way to do accomplish the case above. I've looked into things like TPL Dataflow, also considered a pattern doing a simple "event loop" with deltatime (like in video games), what are your suggestions?</p>
<p>Best regards,</p>

Why is Python datetime time delta not found? : <p>I am trying to make an array of dates in mmddyyyy format. The dates will start on the current day and then go two weeks into the future. So it all depends on the starting date. When I run my code I get an error that states:</p>
<pre><code>Traceback (most recent call last):
File "timeTest.py", line 8, in <module>
day = datetime.timedelta(days=i)
AttributeError: type object 'datetime.datetime' has no attribute 'timedelta'
</code></pre>
<p>I am not sure why this is happening because after searching online, I noticed that people are using the 'timedelta' in this way.</p>
<p>Here is my code:</p>
<pre><code>import time
from datetime import datetime, date, time, timedelta
dayDates = []
today = datetime.now()
dayDates.append(today.strftime("%m%d%Y"))
for i in range(0,14):
day = today + datetime.timedelta(days=i)
print day
</code></pre>

Using this inside loop : <p>I'm trying to use <code>this</code> inside loop, without jQuery. For some reason, it doesn't work. Why?</p>
<pre><code><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<a href="https://google.foo">Google</a>
<script>
/*
// Plain JS - Works
function doSomething() {
var links = document.querySelectorAll('a');
for (var i = 0; i < links.length; i++) {
links[i].href = links[i].href.replace('foo', 'bar');
}
}
// jQuery - Works
function doSomething() {
$('a').each(function() {
$(this).attr('href', $(this).attr('href').replace('foo', 'bar'));
});
}
*/
// Plain JS - Doesn't work
function doSomething() {
var links = document.querySelectorAll('a');
for (var i = 0; i < links.length; i++) {
this[i].setAttribute('href', this[i].getAttribute('href').replace('foo', 'bar'));
}
}
doSomething();

why function pointer to make it difficult ~ : from [Wikipedia - Function object](https://en.wikipedia.org/wiki/Function_object)
> A typical use of a function object is in writing callback functions. A callback in procedural languages, such as C, may be performed by using function pointers.[2] However it can be difficult or awkward to pass a state into or out of the callback function. This restriction also inhibits more dynamic behavior of the function. A function object solves those problems since the function is really a façade for a full object, carrying its own state.
1. why function pointer to make it difficult `pass a state into or out of the callback function` and `dynamic behavior of the function`
2. if function do not use function pointer how programs can called function | 0debug |
