"Use primitive buffers, bytes & arrays to handle strings." In Rust, String is Vec<u8> with a UTF-8 invariant. In Go, string is a pointer + length over bytes. In C, strings are literally char*. He's telling people to replace strings with… strings, but without the invariants and

C: Callbacks or Function Pointers A function pointer in a C is a variable that stores the memory address of a function. This allows the function to be called through the pointer. The image breaks down the syntax of a function pointer declaration into three main parts: Return

Completely occupied by data mesh found a repository related to it all though I am into looking more and more to this github.com/lynnlangit/lea…

If I had to learn system design fundamentals from scratch, I would read the following 16 curated articles (links below): ↓

I'm so happy to have people like Pavan-Nambi contributing to Turso. You can help build an alternative to SQLite while still making SQLite better. That's what a good open source citizen does. Great work!

I did a quick writeup of why I think TSRX is worth talking about: hackmd.io/@0u1u3zEAQAO0i…

Great to see Turso using Quint not only for fun but also for profit ..

I could have explained things much better if it weren't impromptu, but watch this if you want a glimpse of what compile time execution and metaprogramming can do in Jai. All while being fully debuggable and statically type safe

Tomorrow I'll be telling students about list initialization in C++ and may God have mercy upon those poor souls

Rebuilt stuff to be crossed from the Win32 side on 3.51 and surprisingly most of it works on NT 4 POSIX subsystem! Return codes seem to have shifted confusing GCC, but the manual phases seem okay. I know by 1994 we had better options for running stuff, but it's fun abusive POSIX

Thank you MSVC (Clang has the same behavior, for whatever reason)

For those who think that's bad, you should write a compiler ;p

Some fascinating ideas here, DB nerds should check this out

A first-time contributor submitted a major patch to lld, developed largely using Copilot SWE and Codex. github.com/llvm/llvm-proj… The influx of AI-generated patches is becoming a real burden. We need privilege levels for agentic coding in llvm-project. discourse.llvm.org/t/concerns-abo…

Understand these 6 things about file descriptors in Linux 1. Everything is a file - sockets, pipes, devices, actual files. One abstraction, same kernel interface. 2. The FD is just a number - the kernel holds the real state. Your process holds a reference to it. 3. Open does not

I saw this, and created this

This is a nice trick called LoopFrog dl.acm.org/doi/full/10.11… Using an LLVM-based compiler to insert hints, we achieve a geometric mean loop speedup of 43%, translating to whole-program speedups of 9.5% on SPEC CPU 2017 benchmarks, with only modest area and power overheads. 1/3

I checked and it's been 2 years since my last blog post??? So anyway, here's a quick blog post about KDP pool - the latest KDP feature that will replace the secure pool in future Windows versions: windows-internals.com/goodbye-secure…
