Products that do what Less Slow C++ does
Earlier this year, I took a month to reexamine my coding habits and rethink some past design choices. I hope to rewrite and improve my FOSS libraries this year, and I needed answers to a few questions first. Perhaps some of these questions will resonate with others in the community, too. - Are coroutines viable for high-performance work? - Should I use SIMD intrinsics for clarity or drop to assembly for easier library distribution? - Has hardware caught up with vectorized scatter/gather in AVX-512 & SVE? - How do secure enclaves & pointer tagging differ on Intel, Arm, & AMD? - What's…

Hi guys, Two days ago I published the fourth post in the series and thought it would now be a good time to look for additional feedback here on Hacker News. The aim of the series (as mentioned in the first post) is to inspire more people to start using Qt. My ambition is to answer the following questions "what is the gist of Qt?"; "what is the 20% that you need to know to develop 80% of the application?"; "what are the perhaps unknown unknowns?". In other words, I'm just covering basics: enough to understand the concepts and where to find additional information should you need it. Do you…

Hi! Last year in August I've released my first self-published book. C++17 In Detail Available at Leanpub: https://leanpub.com/cpp17indetail Keeping up with the latest changes in the language is quite hard. C++ moves quite fast recently, and there are many exciting features added with each iteration. The book shows all the significant changes in the language and the Standard Library. The chapters are much easier to grasp than reading reference pages or the Standard itself. It's a great guide for any C++ developer who knows a little about C++11/14 and wants to move forward.…

This is a personal project I've been working on and off for the past few years. It's a set of tools that have allowed me to prototype quickly small (and increasingly bigger) kernels, and create userspace programs to interact with them. Supports riscv64, amd64 and i386. The intel port has been tested and used on real hardware, from big dual-socket Xeon machines to an old X220. It is all C, I have plan to make rust bindings for the kernel library. But again, they're plans at this stage. Porting to new architectures is relatively simple, a basic port to riscv took me a couple of weeks of…

You know that old TI calculator you used in high school, then put in a box and forgot about? Have you ever wished you had an operating system for your calculator with preemptive multitasking, dynamic memory management, a tree filesystem conforming to the FHS, and all the comforts of Unix? Well, good news: that's totally a thing that exists. I've been working on my kernel for about three and a half years now and I'm looking for new contributors to help out. It's written entirely in z80 assembly, and it's both challenging and fun to work on. There's an IRC channel for contributors or people…

tl;dr I'm developing an incredibly fast library for arrays and mathematics, and I've implemented a few new features and made some improvements. I'd love for you to check it out! Links: GitHub: https://github.com/LibRapid/librapid/ Documentation: https://librapid.readthedocs.io/en/latest/ Discord: https://discord.com/invite/cGxTFTgCAC Hey everyone! I am the lead developer of LibRapid (https://github.com/LibRapid/librapid/), a high-performance C++ library for array manipulation and mathematics. I've…

Democratisation of local AI is key. I've been working on pushing the limits of commercial hardware, squeezing any extra bit possible. My Scientific Agentic AI hareness helped me to reallocate every single bit of it. I rewrote the Kernel, I went down the CUDA rabbit hole until I have been able to explain any bit and any ms of computational power involved in the process pushing the Qwen 30B-A3B from 8 tok7s to 19 tok/s with llama.cpp up to 22.2 tok/s with my project and 109 tok/s on not novel content and speeding up the prefill by 5-9X

The main goal of this was to be able to not just run multiple Claude Code sessions at once, but actually manage them and keep track of what I was doing. Sometimes this is multiple attempts on the same task, sometimes I work several tasks at once. Really I was just sick of twiddling my thumbs waiting for the coding agent to finish, and I wanted it to be easy to work on/review/test another change while I waited.

I participated in the Nvidia + Vercel 2 hour hackathon in SF tonight, and built something I've wanted, but hadn't tried building. I implemented an MCP Server and VS Code extension to allow Claude Desktop to place breakpoints, step through code, and execute expressions (assuming language support). So you can ask it a question that requires actually stepping through the code and now it can actually do that - check values for you, etc. It's _definitely_ not perfect. Have improvements? Please make a PR!

I must say I was encouraged to post my project here when I saw the positive response to this post: http://news.ycombinator.com/item?id=3780731 Before you make any comments, please keep in mind that the project is written for fun. I'm not forcing anyone to use it. In fact, nobody should use the current unstable version in a serious project. Here is the link: http://github.com/bsg/libserv Please share your thoughts. All criticisms are welcome, even the harsh ones. p.s. The project is still a work-in-progress.

Hey everyone! I am excited to share updates on four of my & my teams' open-source projects that take large-scale search systems to the next level: USearch, UForm, UCall, and StringZilla. These projects are designed to work seamlessly together, end-to-end—covering everything from indexing and AI to storage and networking. And yeah, they're optimized for x86 AVX2/512 and Arm NEON/SVE hardware. USearch [1]: Think of it as Meta FAISS on steroids. It's now quicker, supports clustering of any granularity, and offers multi-index lookups. Plus, it's got more native bindings than probably…

Hi, I work on this library because I like the simplicity of CGI and enjoy building things with C++. It is based on asio and my own implementation of FastCGI, and it works on both Linux and Windows. I have just released the new version and created a simple live demo that you can check out here: https://asyncgi-guestbook.eelnet.org

I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.
