<p>Just a quick questionin my Database class I have declared the database variables at the start of the class. see below:</p>
<pre><code> private static final String DATABASE = ".....";
private static final String DRIVER = "....";

<p>Is this the best way to do this or would I be best creating an enum and accessing them through that?</p>

<p><strong>Step 4</strong>: Run the application in <code>Debug</code> <code>x64</code>. You should see this label:</p>
<blockquote>
<p>42.5 , 42.5 => 107.5 , 107.5</p>
</blockquote>
<p><strong>Step 5</strong>: Run the application in <code>Release</code> <code>x64</code>. You should see this label:</p>
<blockquote>
<p>-7.5 , -7.5 => 7.5, 7.5</p>
</blockquote>
<p><strong>Step 6</strong>: Uncomment <code>line 45</code> in <code>MainPage.xaml.cs</code> and repeat step 5. Now you see the original label</p>
<blockquote>
<p>42.5 , 42.5 => 107.5 , 107.5</p>
</blockquote>
<hr>
<p>By commenting out <code>line 45</code>, the code will use <code>Rectangle2D.Inflate2(...)</code> which is exactly the same as <code>Rectangle2D.Inflate1(...)</code> except it creates a local copy of the computations before sending them to the constructor of <code>Rectangle2D</code>. In debug mode, these two function exactly the same. In release however, something is getting optimized out.</p>
<p>This was a nasty bug in our app. The code you see here was stripped from a much larger library and I'm afraid there might be more. Before I report this to Microsoft, I would appreciate it if you could take a look and let me know why <code>Inflate1</code> doesn't work in release mode. Why do we have to create local copies?</p>

37,911,838 | How to use MongoDB with promises in Node.js? | <p>I've been trying to discover how to use MongoDB with Node.js and in the docs it seems the suggested way is to use callbacks. Now, I know that it is just a matter of preference, but I really prefer using promises.</p>
<p>The problem is that I didn't find how to use them with MongoDB. Indeed, I've tried the following:</p>
<pre><code>var MongoClient = require('mongodb').MongoClient;
var url = 'mongodb://localhost:27017/example';
MongoClient.connect(url).then(function (err, db) {
console.log(db);
});
</code></pre>

<p>I have a classic cross site scripting scenario: An ASP.Net Core solution where users can edit text using a WYSIWYG html-editor. The result is displayed for others to see.

So i've thought that maybe on each function (like voteup, votedown, write post, create topic etc) i'll be parsing a json to my logic and then from getting that json i'll be making some actions. But im not sure if its possible in C# and couldn't find any similar soultion on web. Maybe by making each function some kind of async i could get the goal?

37,924,144 | Using function with return type Task<T>...c# | ASP.NET MVC 5/ C# .NEt 4.6.1
I had a function that did the following:
public class UserClass
{
public static CurrentUserData GetUserInfo()
{
CurrentUserData ui;
ui = GetUserData();
return ui;
}
}
My CurrentUserData object is as follows:
public class CurrentUserData
{
public bool ReadOnly{get;set;}
}
In my controller, I call my method and can see the ReadOnly property fine:
var user = UserClass.GetUserInfo();
if (user.ReadOnly)
{
////code to execute
}
I had to add an async call to my function, and now it looks likes this (I omitted code for brevity):
public static Task<CurrentUserData > GetUserInfo()
{
Task<CurrentUserData > ui;
ui = GetUserData();
HttpResponseMessage response = await httpClient.SendAsync(request);
return ui;
}
Notice the Task<T> I had to add. But when I call the method in my controller like before, I get the error:
Error CS1061 'Task<CurrentUserData >' does not contain a definition for
'ReadOnly' and no extension method 'ReadOnly' accepting a first argument of
type 'Task<CurrentUserData >' could be found (are you missing a using directive or
an assembly reference?)
What do I need to change so when any class calls my new Task<CurrentUserData > method, it will see all the properties of the object wrapped in Task<CurrentUserData >?
Thanks

37,924,377 | Does Pandas calculate ewm wrong? | <p>When trying to calculate the exponential moving average (EMA) from financial data in a dataframe it seems that Pandas' ewm approach is incorrect.</p>
<p>The basics are well explained in the following link:
<a href="http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:moving_averages" rel="noreferrer">http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:moving_averages</a></p>
<p>When going to Pandas explanation, the approach taken is as follows (using the "adjust" parameter as False):</p>
<pre><code> weighted_average[0] = arg[0];
weighted_average[i] = (1-alpha) * weighted_average[i-1] + alpha * arg[i]
</code></pre>
<p>This in my view is incorrect. The "arg" should be (for example) the closing values, however, arg[0] is the first average (i.e. the simple average of the first series of data of the length of the period selected), but NOT the first closing value. arg[0] and arg[i] can therefore never be from the same data. Using the "min_periods" parameter does not seem to resolve this.</p>
<p>Can anyone explain me how (or if) Pandas can be used to properly calculate the EMA of data?</p>

<p>This code is all inside Add_client.
The error Add_client.java:76 is referring to the line: <code>SQLiteDatabase db = mDbHelper.getWritableDatabase();</code>
The error Add_client.java:67 is referring to the line: <code>saveData();</code>
Which is probably caused by line 76.</p>
<p>I made sure that there are columns inside the database, by executing <code>System.out.println("Column count:" + c.getColumnCount());</code></p>
<p>This told me that there where 3 columns, which is what I was expecting.
I also checked if there was any data inside the columns with:</p>
<pre><code>Boolean rowExists;
if (c.moveToFirst())

rowExists = true;
} else
{
System.out.println("Nothing to see here");
rowExists = false;
}
</code></pre>
<p>This gave me the output: Nothing to see here, which is was also expecting because the database starts empty.</p>
<p>Where is the mistake in my code which keeps smashing me these errors?</p>
<p>Is there is any other information needed, I will be happily include it in an edit.</p>

I need to also check for if there are any 0's before the value also.
for example. 0001.23 should throw and error. but 1.23 should be ok.
Is there a way to add this to the current regex check.

37,934,972 | Serviceworker conflict with HTTP basic auth? | <p>I'm trying to protect a site during an early stage of development from casual prying eyes. Basic auth over HTTPS seemed like a reasonable solution but the presence of a serviceworker seems to prevent it from working in Chrome. This happens specifically if a serviceworker is already installed, but the browser does not have an active authorisation for the desired realm.</p>
<p>Chrome shows that the response was a 401 in the network timeline</p>
<p><a href="https://i.stack.imgur.com/WUole.png" rel="noreferrer"><img src="https://i.stack.imgur.com/WUole.png" alt="401 in Network timeline"></a></p>

<pre><code>HTTP/1.1 401 Unauthorized
WWW-Authenticate: Basic realm="My realm"
Date: Tue, 21 Jun 2016 03:09:35 GMT
Connection: close
Cache-Control: no-cache
</code></pre>
<p>But it does not prompt for a login, it just shows the content body of the 401 response.</p>

37,936,560 | How to Sign Out of Google After Being Authenticated | <p>So my app has the option to sign in with Google. Upon clicking the button that Google provides, a web view opens and has the user input their credentials. After allowing the app to access their information the app then signs the user in and changes the SignInViewController to the TabBarController (where they can now interact accordingly).</p>
<p>When the user presses a Signout button they are directed to the login screen as one would expect. But the odd thing is, if the user presses the google button again they are automatically signed in with no further authentication at all and no option to remove their account. Is their a way to clear the google account credentials as to protect the users from accidental theft?</p>

37,942,063 | Slow insert on PostgreSQL using JDBC | <p>I work on a system which downloads data from a cloud system to a local database (PostgreSQL, MySQL, ...). Now I'm having an issue with PostgreSQL performance because it takes a lot of time to insert the data.</p>
<p>A number of columns and the size of the data may vary. In a sample project, I have a table with approx. 170 columns. There is one unique index - but even after dropping the index the speed of the insert did not change.</p>
<p>I'm using JDBC driver to connect to the database and I'm inserting data in batches of 250 rows (using <a href="http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/jdbc/core/namedparam/NamedParameterJdbcTemplate.html">NamedParameterJdbcTemplate</a>).</p>
<p>It took me approx. <strong>18 seconds to insert the data on Postgres</strong>. The same data set <strong>on MySQL took me just a second</strong>. That's a huge difference - where does it come from? Is Postgres JDBC driver that slow? Can it be configured somehow to make it faster? Am I missing something else? The difference between Postgres and MySQL is so huge. Any other ideas how to make it faster?</p>

37,944,111 | Python rolling log to a variable | <p>I have an application that makes use of multi-threading and is run in the background on a server. In order to monitor the application without having to log on to the server, I decided to include <a href="http://bottlepy.org" rel="noreferrer">Bottle</a> in order to respond to a few HTTP endpoints and report status, perform remote shutdown, etc.</p>
<p>I also wanted to add a way to consult the logfile. I could log using the <code>FileHandler</code> and send the destination file when the URL is requested (e.g. <code>/log</code>).</p>
<p>However, I was wondering if it'd be possible to implement something like a <code>RotatingFileHandler</code>, but instead of logging to a file, logging to a variable (e.g. <code>BytesIO</code>). This way, I could limit the log to the most recent information, while at the same time being able to return it to the browser as text instead of as a separate file download.</p>
<p>The <code>RotatingFileHandler</code> requires a filename, so it's not an option to pass it a <code>BytesIO</code> stream. Logging to a variable itself is perfectly doable (e.g. <a href="http://alanwsmith.com/capturing-python-log-output-in-a-variable" rel="noreferrer">Capturing Python Log Output In A Variable</a>), but I'm a bit stumped on how to do the <em>rolling</em> part.</p>
<p>Any thoughts, hints, suggestions would be greatly appreciated.</p>
