The query string is the part of a request following the URL, preceded by a ? mark. Example: https://encrypted.google.com/search?hl=en&q=stack%20overflow For this example, we are making a simple echo webserver that echos back everything submitted to it via the echo field in GET requests. Examp...
Flask also allows access to a CombinedMultiDict that gives access to both the request.form and request.args attributes under one variable. This example pulls data from a form field name submitted along with the echo field in the query string. Flask Example: from flask import Flask, request app...
You can access the form data submitted via a POST or PUT request in Flask via the request.form attribute. from flask import Flask, request app = Flask(import_name=__name__) @app.route("/echo", methods=["POST"]) def echo(): name = request.form.get("name"...
In Swift 1 and 2, closure parameters were escaping by default. If you knew your closure wouldn’t escape the function body, you could mark the parameter with the @noescape attribute. In Swift 3, it’s the other way around: closure parameters are non-escaping by default. If you intend for it to escape...
From Swift Documentarion @escaping Apply this attribute to a parameter’s type in a method or function declaration to indicate that the parameter’s value can be stored for later execution. This means that the value is allowed to outlive the lifetime of the call. Function type parameters wi...
When executing a search, it will be broadcast to all the index/indices shards (round robin between replicas). Which shards will be searched on can be controlled by providing the routing parameter. For example, when indexing tweets, the routing value can be the user name: curl -XPOST 'localhost:9200...
.profile is read by most shells on startup, including bash. However, .bash_profile is used for configurations specific to bash. For general initialization code, put it in .profile. If it's specific to bash, use .bash_profile. .profile isn't actually designed for bash specifically, .bash_profile is...

On 32-bit systems, integers greater than 0x7FFFFFFF cannot be stored primitively, while integers between 0x0000000080000000 and 0x7FFFFFFFFFFFFFFF can be stored primitively on 64-bit systems but not 32-bit systems (signed long long). However, since 64-bit systems and many other languages support sto...

One major aspect of process substitution is that it lets us avoid usage of a sub-shell when piping commands from the shell. This can be demonstrated with a simple example below. I have the following files in my current folder: $ find . -maxdepth 1 -type f -print foo bar zoo foobar foozoo barzoo ...
Once you have your UWP application ready for tests you should add test application to your solution. To do it "right" click on the solution and choose "Unit Test App (Universal Windows)": Once you add it to the solution there are few more steps required to configure it. You w...
Once your test application is ready you can connect it with code for which you want to write unit tests. Either you have you code in PCL, or in UWP app project (I assume that you applied MVVM pattern) just add reference to it in Test Application project: Now you have access to all your code from...
An artifact built by Maven can be declared as a Maven plugin by specifying the packaging as maven-plugin in the pom.xml. <packaging>maven-plugin</packaging> You need to declare a dependency on the plugin API and annotations. <dependency> <groupId>org.apache.maven&lt...
