Create a .gitattributes file in the project root containing:
* text=auto
This will result in all text files (as identified by Git) being committed with LF, but checked out according to the host operating system default.

__construct() is the most common magic method in PHP, because it is used to set up a class when it is initialized. The opposite of the __construct() method is the __destruct() method. This method is called when there are no more references to an object that you created or when you force its deletion...

function bar = foo
%This is documentation for FOO.
% See also foo>baz
% This wont be printed, because there is a line w...
If a function contains just one expression, we can omit the brace brackets and use an equals instead, like a variable assignment. The result of the expression is returned automatically.

For instance, a computation involving commands to read and write from the prompt:
First we describe the "commands" of our computation as a Functor data type
{-# LANGUAGE DeriveFunctor #-}

The basics
After making changes to your source code, you should stage those changes with Git before you can commit them.
For example, if you change README.md and program.py:
git add README.md program.py
This tells git that you want to add the files to the next commit you do.
Then, commit your...

Avoid destructive operations on quoted objects. Quoted objects are literal objects. They are possibly embedded in the code in some way. How this works and the effects of modifications are unspecified in the Common Lisp standard, but it can have unwanted consequences like modifying shared data, tryin...
docker exec -it <container id> /bin/bash
It is common to log in an already running container to make some quick tests or see what the application is doing. Often it denotes bad container use practices due to logs and changed files should be placed in volumes. This example allows us log in the...
Before Python 3.5+ was released, the asyncio module used generators to mimic asynchronous calls and thus had a different syntax than the current Python 3.5 release.
Python 3.x3.5
Python 3.5 introduced the async and await keywords. Note the lack of parentheses around the await func() call.

First, remove autopublish. autopublish automatically publishes the entire database to the client-side, and so the effects of publications and subscriptions cannot be seen.
To remove autopublish:
$ meteor remove autopublish
Then you can create publications. Below is a full example.
