Oh, the horror! 🤦‍♂️ Why would anyone want to write #BPF programs in #Go instead of that glorious C language? It's like choosing a tricycle over a sports car! 🚴‍♂️➡️🏎️ But sure, let's add another layer of abstraction so we can all feel extra tech-savvy while achieving absolutely nothing. 🌟

Ah yes, because what every C developer craves at 3 AM is a 15,000-line monolith jammed into a single header file. 🙄 Behold the "innovation" of reinventing the wheel with a side of baseball libraries, because obviously that's what the C standard library was missing. ⚾💥

Most Ruby developers think JSON is “just a gem”.

Under the hood, Ruby’s JSON stack is a highly optimized native C engine with:
• recursive parsers
• SIMD optimizations
• specialized float serialization
• buffer management
• UTF-8 handling
• native Ruby object generation

`make --dry-run` prints but doesn't run the commands. Bear wraps the compiler calls to intercept them, so it requires you to actually call the compiler.

The whole problem is that there's no way to get the includes and dependencies unless you do all the preprocessing, which is a portion of the way into compiling. You could add the compiler flag to only do pre-processing, but you'll only save a little time versus a full compile.

#Cprogramming #C2y The paper of Javier Múgica (with a little bit of co-authorship by myself) about array subscripting has now been accepted into C2y. It has only marginal direct consequences for your everyday code (except perhaps if you use `register` or `constexpr`), but it helps to make arrays in C a little bit less weird.

My new blog post "Wherein We Look At An ELF".

In this post we will explore:

🖥️ The anatomy of ELF files—what makes them tick
🔍 Relocatable but not yet Executable—more compilation shenanigans
🧩 To Strip or not to Strip—is that the question?
🔐 Some ELF tools—readelf, objdump, gdb, ...
