Brainfuck to RISC-V JIT compiler written in Zig
Hi everybody, this was my project to learn Zig and RISC-V+x86_64 assembly. Not sure if anybody is actually interested in yet another Brainfuck compiler, so I'll just write up some random things I learned while building it! - A primitive assembly stitching compiler is 10x faster than the interpreter. Did not expect that. - The generated x86 code is really bad (e.g. it always uses 6 or 7 byte sized instructions with 32-bit immediates when there are much smaller ones) but it doesn't really matter. Good code generated by GCC and clang for transpiled Brainfuck->C is not much faster as it's…

What it does
Interactive Brainfuck compiler/interpreter/profiler/transpiler written in Zig - evelance/brainiac
Brainiac is a user-friendly and feature-rich Brainfuck runtime. It runs interactively in the terminal and includes an optimizing interpreter and native code compiler for riscv64 and x86_64. For complete files a profiler and a transpiler for C and Zig are available. It's fast, memory safe, and colorful! Brainfuck is a minimalist esoteric programming language designed to challenge and amuse programmers with its extreme simplicity yet Turing-completeness. The language consists of eight commands and an infinite memory tape. Other characters are ignored, allowing for creative code layouts and comment styling. Despite its minimalism, Brainfuck is Turing-complete, allowing it to compute any…from github.com

Talanoa▲346Hi 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▲1,125We 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 →…
