Show HN: Hexi, modern header-only network binary serialisation for C++ hackers https://ift.tt/L7KbyTE

Show HN: Hexi, modern header-only network binary serialisation for C++ hackers Over the last few years, I've needed an easy way to quickly serialise and deserialise various network protocols safely and efficiently. Most of the libraries that existed at the time were either quite heavy, had less than stellar performance, or were an abstraction level above what I was looking for. I decided to put together my own class to do the job, starting with an easy, low-overhead way to move bytes in and out of arbitrary buffers. Along the way, it picked up useful bits and pieces, such as buffer structures and allocators that made the byte shuffling faster, often being able to do it with zero allocations and zero copies. Safety features came along to make sure that malicious packet data or mistakes in the code wouldn't result in segfaults or vulnerabilities. It's become useful enough to me that I've packaged it up in its own standalone library on the chance that it might be useful to others. It has zero dependencies other than the standard library and has been designed for quick integration into any project within minutes, or seconds with a copy paste of the amalgamated header. It can be used in production code but it's also ideal for for those that want to quickly hack away at binary data with minimal fuss. https://ift.tt/z6aRG3g March 28, 2025 at 11:07PM

Show HN: FancyLock – Linux screenlock with videos. Wayland support coming soon https://ift.tt/latgx1V

Show HN: FancyLock – Linux screenlock with videos. Wayland support coming soon I've been wanting a fancy screen locker for linux, so I built FancyLock, a screen lock solution for Linux with X11 (and soon wayland) support. Key Features - Dynamic media playback during lock screen - Multi-monitor support - PAM-based authentication - Intelligent idle timeout - Highly configurable FancyLock aims to solve several pain points with existing screen lockers: - Boring, static lock screens - Poor multi-monitor support Technical Highlights - Written in Go - Uses X11 extensions for low-level window and input management - Flexible media playback with mpv - Configurable via JSON Current version is v0.0.1 and supports X11. Wayland support is planned. GitHub: https://ift.tt/QHgoRPf Would love to hear your thoughts and feedback! Edit: Happy to answer any questions about the implementation or design choices. https://ift.tt/QHgoRPf March 28, 2025 at 03:03AM

Show HN: Xorq – open-source Python-first Pandas-style pipelines Hi HN, Dan, Hussain and Daniel here… After years of struggling with data pipelines that worked in notebooks but failed in production, we decided to do something about it. We created xorq to eliminate the constant headaches of SQL/pandas impedance mismatch, runtime debugging, wasteful recomputations and unreliable research-to-production deployments that plague traditional pandas-style pipeline workflows. xorq is built on Ibis and DataFusion. We’d love your feedback and contributions. xorq is [Apache 2.0 licensed]( https://ift.tt/1AJrRNS ) to encourage open collaboration. Repo : https://ift.tt/ZTY5gEh Docs : https://docs.xorq.dev Roadmap Issues : https://ift.tt/ZTY5gEh You can get started `pip install xorq`. Or, if you use nix, you can simply run `nix run github:xorq-labs/xorq` and drop into an IPython shell. Demo video: https://youtu.be/jUk8vrR6bCw Here are some vignettes to look into next: 1. MCP Server + Flight + XGBoost: https://ift.tt/1g9DCvZ 2. 1 DuckDB + 2 Writers + 1 Reader: https://ift.tt/y3B2DeK 3. OpenAI UDF: https://ift.tt/ZYJMBAC Some features to note: - Ibis-based multi-engine expression system: effortless engine-to-engine streaming - Cache expressions with `.cache` operator - Portable DataFusion-backed UDF engine with first class support for pandas dataframes - Serialize Expressions to and from YAML - Easily build Flight end-points by composing UDFs thanks for checking this out, and we’re here to answer any questions! https://ift.tt/t1Ya7SK March 27, 2025 at 10:57PM

Show HN: Taildrops – Free Tailwind CSS 4 code snippets Free Tailwind CSS 4 Components — and this is just the beginning! I’ve been sharing a bunch of free Tailwind CSS components on X, but honestly, they just keep getting buried in the timeline. It’s super frustrating when something you put effort into disappears so quickly. That’s why I decided to put everything on a website. Now you can easily find all the components I’ve shared in one place, and I’ll keep adding any new ones I create. It feels good to have a space where they won’t get lost. Check them out if you’re interested — I’d love to hear what you think! https://taildrops.com/ March 27, 2025 at 02:59AM
