Quirks of C

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

struct foo {
   struct bar {
 int x;

Using cycript on macOS Mojave

Cycript on Mojave

Cycript is a tool I find very helpful. It's an effective REPL for Objective-C. When I updated to macOS Mojave, I found that cycript no longer worked because it was linked against an old version of Ruby. After attempting to compile from source, I tried another solution. install_name_tool is an open source tool for modifying the names of linked shared libraries in a Mach-O.

Solution

$ install_name_tool -change /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/libruby.dylib Cycript.lib/cycript-apl
$ install_name_tool -change /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/libruby.dylib Cycript.lib/libcycript.dylib

Writing an OS in Rust to run on RISC-V

(This is a translation of the original article in Japanese by moratorium08.)

(UPDATE (22/3/2019): Added some corrections provided by the original author.)

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

Recommended OptiFine alternatives on Fabric

The list is moving out!

If you share this list, please use this link instead: https://lambdaurora.dev/optifine_alternatives

It may still be only a redirection link, but it will have a better web display of the list soon. And the list being on GitHub/GitHub pages improves load times.

The gist version of this list will stop being updated.

Why?

GDB for Switch Modding Cheatsheet/Tutorial

This is a mini-tutorial of sorts for getting started with gdb on the Switch, with the target audience being people who want to mod and/or reverse games, with no prerequisite knowledge of gdb. The goal will be to walk you through some of the basic workflows needed to use a debugger on the Switch, while being brief enough for skimming for when you forget things.

If some part is unclear, your OS doesn't have install instructions, or you feel part of your workflow should be added here, feel free to comment any additions.

(If you only need a quick reference Jump to the Appendix)

Installing GDB

First off you'll need a version of GDB compatible with aarch64. This can be obtained via either a distribution of
