LoopMix128 – Fast C PRNG (.46ns), 2^128 Period, BigCrush/PractRand Pass

In plain words

LoopMix128 is a fast C pseudorandom number generator for non-cryptographic applications. It generates values at approximately 0.37 nanoseconds per output, passes statistical tests including TestU01 BigCrush and PractRand across 32TB of data, and guarantees a 2^128 period. The generator is proven injective, enabling parallel random streams, and requires only the standard integer library. It is designed for developers needing high-performance random number generation in C projects.

A very fast and robust 64-bit PRNG with a minimum 2^64 period. - danielcota/biski64

This repository contains biski64 , an extremely fast pseudo-random number generator (PRNG) with a guaranteed minimum period of 2^64. It is designed for non-cryptographic applications where speed and statistical quality are important. The library is available on crates.io and the documentation can be found on docs.rs . [ dependencies ] biski64 = " 0.3.2 " rand = " 0.9 " Basic Usage use rand :: { RngCore , SeedableRng } ; use biski64 :: Biski64Rng ; let mut rng = Biski64Rng :: seed_from_u64 ( 12345 ) ; let num = rng . next_u64 ( ) ; Performance Rust: biski64 0.401 ns/call xoshiro256++ 0.610 ns/call xoroshiro128++ 0.883 ns/call C: biski64 0.368 ns/call wyrand 0.368 ns/call sfc64 0.368 ns/call…from github.com

  DualMix128 – A fast, simple PRNG passing PractRand (32TB) and BigCrush2025 · github.com · ▲5

  Hi HN, I'd like to share DualMix128, a pseudo-random number generator I developed. It's written in C and achieves very high speed while maintaining strong statistical properties for non-cryptographic use. GitHub (MIT License): https://github.com/the-othernet/DualMix128 Key points: * *Fast:* Benchmarked at ~0.36 ns per 64-bit generation on GCC 11.4 (-O3 -march=native). This was over 2x faster than `xoroshiro128++` (~0.74 ns) and competitive with `wyrand` (~0.36 ns) in the same tests. (Benchmark code/results in repo). * *Robust:* Passes the full TestU01 BigCrush suite…

  Fast Random Library for C++172025 · github.com · ▲52

  Morning HN. Random number generation feels is a somewhat underrepresented topic in the C++ realm. There is a lot of questionable info about it found online and even the standard library is quite behind the times in terms of it's algorithms. It suffers from trying to accommodate sometimes impractical standard requirements and has several ways of getting significantly bad statistical results. This leaves a lot easily achievable performance & quality on the table. So, being a mathematician who mostly works with stochastic models and wants these models to run fast and well, I embarked on a…

  Xcc700: Self-hosting mini C compiler for ESP32 (Xtensa) in 700 linesDec 2025 · github.com · ▲154

  Repo: https://github.com/valdanylchuk/xcc700 Hi Everyone! I just wrote my first compiler! - single pass, recursive descent, direct emission - generates REL ELF binaries, runnable using ESP-IDF elf_loader - very basic features only, just enough for self-hosting - treats the Xtensa CPU as a stack machine for simplicity, no register allocation / window usage - compilable on Mac, probably also Linux, can cross-compile for esp32 there - wrote for fun / cyberdeck project Sample output from esp32: xcc700.elf xcc700.c -o /d/cc.elf [ xcc700 ] BUILD COMPLETED >…

  A hash array-mapped trie implementation in C2023 · github.com · ▲171

  Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
