The base64 module also includes encoding and decoding functions for Base16. Base 16 is most commonly referred to as hexadecimal. These functions are very similar to the both the Base64 and Base32 functions: import base64 # Creating a string s = "Hello World!" # Encoding the string into...

Adobe created it's own encoding called ASCII85 which is similar to Base85, but has its differences. This encoding is used frequently in Adobe PDF files. These functions were released in Python version 3.4. Otherwise, the functions base64.a85encode() and base64.a85encode() are similar to the previous...

Just like the Base64, Base32, and Base16 functions, the Base85 encoding and decoding functions are base64.b85encode() and base64.b85decode(): import base64 # Creating a string s = "Hello World!" # Encoding the string into bytes b = s.encode("UTF-8") # Base85 Encode the byte...

Instead of typing our HTML markup into the return statements, we can use the render_template() function: from flask import Flask from flask import render_template app = Flask(__name__) @app.route("/about") def about(): return render_template("about-us.html") if __n...

The traditional GLSL compilation model involves compiling code for a shader stage into a shader object, then linking multiple shader objects (covering all of the stages you want to use) into a single program object. Since 4.2, program objects can be created that have only one shader stage. This met...

To view your installed packages or themes, open settings with Ctrl+, and select either the "Packages" or "Themes" tab in the left-hand navigation bar. Note, the packages or themes you installed from other publishers will show up under the "Community Themes" section and ...

map() is a built-in function, which means that it is available everywhere without the need to use an 'import' statement. It is available everywhere just like print() If you look at Example 5 you will see that I had to use an import statement before I could use pretty print (import pprint). Thus ppr...

Keras is a high-level neural networks library, written in Python and capable of running on top of either TensorFlow or Theano. It was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing good research. Use Keras ...

Locking on an stack-allocated / local variable One of the fallacies while using lock is the usage of local objects as locker in a function. Since these local object instances will differ on each call of the function, lock will not perform as expected. List<string> stringList = new List<st...

The continue statement in Objective-C programming language works somewhat like the break statement. Instead of forcing termination, however, continue forces the next iteration of the loop to take place, skipping any code in between. For the for loop, continue statement causes the conditional test a...

send() is used to pass message to object. send() is an instance method of the Object class. The first argument in send() is the message that you're sending to the object - that is, the name of a method. It could be string or symbol but symbols are preferred. Then arguments those need to pass in met...

The basic example Open routes/web.php file and paste the following code in file: Route::get('helloworld', function () { return '<h1>Hello World</h1>'; }); here 'helloworld' will act as page name you want to access, and if you don't want to create blade file and still want to ...

Bullet This one particularly blew my mind. The bullet gem helps you kill all the N+1 queries, as well as unnecessarily eager loaded relations. Once you install it and start visiting various routes in development, alert boxes with warnings indicating database queries that need to be optimized will p...

Along with other more advanced text editors, Atom allows developers to open a single file or a directory. Opening Files To open files with Atom, either use File > Open File... in the menu as show below: or use the faster keyboard shortcut: Ctrl+O (For Mac OS: ⌘+O). This will open a file expl...

TypeScript supports interfaces, but the compiler outputs JavaScript, which doesn't. Therefore, interfaces are effectively lost in the compile step. This is why type checking on interfaces relies on the shape of the object - meaning whether the object supports the fields and functions on the interfac...
