Zig type system illustrated using ascii diagrams

Zig Type System

Zig aims to be a simple language. It is not easy to define what simple exactly means, but zig is also a low-level programming language that aims for c-compatibility. To reach this goal, it needs good semantics in its type system so that developers have a complete toolbox to manipulate data.

So types in zig are composable, but this can become rapidly overwhelming. See those examples. Are you able to understand them at a glance, as soon as you read them?

A guide to ANSI on Discord

A guide to ANSI on Discord

Discord is now slowly rolling out the ability to send colored messages within code blocks. It uses the ANSI color codes, so if you've tried to print colored text in your terminal or console with Python or other languages then it will be easy for you.

Quick Explanation

To be able to send a colored text, you need to use the ansi language for your code block and provide a prefix of this format before writing your text:

\u001b[{format};{color}m

zig: `std.x` wishlist
  • Include std.x.os.Reactor.

A high-level I/O event reactor interface that wraps over event notification systems like epoll, kqueue.

Plan is to get epoll done first, kqueue second, select third, then iocp/afd fourth.

  • Include std.x.os.Socket.setLinger(linger_for_num_seconds: ?u16) !void.
  • Include std.x.os.Socket.getRemoteAddress() !std.x.Socket.Address.
  • Include std.x.os.Socket.setKeepAlive(enabled bool) !void.
  • Include std.x.os.Socket.(r|R)eader(flags) and std.x.os.Socket.(w|W)riter(flags).

Super Guide to the split-window tmux Subcommand (and Beyond)

Super Guide to the split-window tmux Subcommand (and Beyond)

Guide overview

tmux, like other great software, is deceptive. On the one hand, it's fairly easy to get set up and start using right away. On the other hand, it's difficult to take advantage of tmux's adanced features without spending some quality alone time with the manual. But the problem with manuals is that they aren't geared toward beginners. They are geared toward helping seasoned developers and computer enthusiasts quickly obtain the

What is Strict Aliasing and Why do we Care?

What is the Strict Aliasing Rule and Why do we care?

(OR Type Punning, Undefined Behavior and Alignment, Oh My!)

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.

In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.

Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th
