iostream.h

iostream.h (ab?)uses _Generic, __builtin_choose_expr, __typeof__, statement expressions, and recursive variadic macro expansion to create a cin and cout for C11+GCC extension compilers.

Should you use this? Of course not. But it's pretty f***ing cool.

C Style Malloc in C aka Void Pointers

One of the most annoying things about C++ is the incompatibility with C's void * conversion. In C, void * can be cast implicitly to any pointer type, but C++ needs an explicit cast.

Most C code is valid C++ code, but the most common issue is malloc, which returns void *.

For example, this is valid C code, but not valid C++ code:

struct Foo *x = malloc(sizeof(struct Foo));

In your local clone of your forked repository, you can add the original GitHub repository as a "remote". ("Remotes" are like nicknames for the URLs of repositories - origin is one, for example.) Then you can fetch all the branches from that upstream repository, and rebase your work to continue working on the upstream version. In terms of commands that might look like:

Add the remote, call it "upstream":

git remote add upstream https://github.com/whoever/whatever.git

Fetch all the branches of that remote into remote-tracking branches, such as upstream/master:

git fetch upstream

Step 1 - Make a Discord Webhook

1. Find the Discord channel in which you would like to send commits and other updates

2. In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe!

Step 2 - Set up the webhook on Github

1. Navigate to your repository on Github, and open the Settings
