24 alternatives to JUring – Java bindings for io_uring file I/O
Hi HN! For the past few weeks, I've been working on bringing io_uring to Java. It started as an experiment, but slowly it became more than just that, and now trying to turn it into a proper library. After hearing talks about virtual threads and io_urings performance I wanted to build something that was faster than Java provides out of the box. I ended up creating two APIs: - A direct one that closely mirrors io_uring's behavior - A blocking one built with Virtual Threads in mind for remote files. This is the link to the project if you are interested…
JUring provides Java bindings for io_uring, a high-performance Linux file I/O interface. It is designed for Java developers seeking faster file operations than standard Java libraries offer. The library offers two… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

A few months ago, I benchmarked FastAPI on an i9 MacBook Pro. I couldn't believe my eyes. A primary REST endpoint to `sum` two integers took 6 milliseconds to evaluate. It is okay if you are targeting a server in another city, but it should be less when your client and server apps are running on the same machine. FastAPI would have bottleneck-ed the inference of our lightweight UForm neural networks recently trending on HN under the title "Beating OpenAI CLIP with 100x less data and compute". (Thank you all for the kind words!) So I wrote another library. It has been a while since I have…

I found hping3 and nmap's nping to be far too slow in terms of sending individual, bare-minimum (40-byte) TCP SYN packets; other than inefficient socket I/O, they were also attempting to do far too much unnecessary processing in what should have otherwise been a tight execution loop. Furthermore, none of them were able to handle CIDR notations (i.e., a range of IP addresses) as their source IP parameter. Being intended for embedded devices (e.g., low-power MIPS/Arm-based routers), Blitzping only depends on standard POSIX headers and C11's libc (whether musl or gnu). To that end,…

This program can be used to tunnel TCP connections through a file. People have used it for interesting things: - Bridging connections which would otherwise be blocked by a firewall - Tunneling through RDP (similar to an SSH tunnel) - Exposing a localhost web server to others Key features I put effort into: 1. The shared file is restarted every 10 MB, so it doesn't grow indefinitely. 2. Optimisations for latency & bandwidth. (800 Mbps on a Gigabit LAN. 108 Mbps if file tunneling through RDP) 3. Synchronisation between two sides (each side can be started and restarted in any order) I'd love to…

[I'm the author] Spall is a web-accessible profiler that I made to help my web-dev friends load gigabyte+ JSON traces without lunch-break-long load times. Recently, Spall got experimental support for auto-tracing with binary traces (along with an in-progress native-port, to give it more memory headroom), which was used to help track down and fix some hard-to-spot lock contention issues in the Odin-language compiler. I demoed it at the Handmade Seattle conference in October, https://guide.handmade-seattle.com/c/2022/spall/, with a head-to-head against Perfetto,…

Author here. I just wanted a quick and easy way to easily submit strings to a REST API and get back the embedding vectors in JSON using Llama2 and other similar LLMs, so I put this together over the past couple days. It's very quick and easy to set up and totally self-contained and self-hosted. You can easily add new models to it by simply adding the HuggingFace URL to the GGML format model weights. Two models are included by default, and these are automatically downloaded the first time it's run. It lets you not only submit text strings and get back the embeddings, but also to compare two…

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…

Hey HN, I've been working on an intercepting proxy for penetration testing over the last few years in my spare time. Some points of difference from the existing tools: * The UIs are built using the native platform frameworks, meaning they look and behave like other applications on the desktop. * It has a fully embedded and integrated Python scripting engine. * It’s fully native meaning it’s nicer on system resources. * It has a number of built in scripts to automate reconnaissance, content discovery, authorisation checks, etc. * The core of it is open source. I'm really keen to get any…

Serialization framework with some interesting numbers: 10-20x faster on nested objects than json/protobuf. Technical approach: compile-time codegen (no reflection), compact binary protocol with meta-packing, little-endian layout optimized for modern CPUs. Unique features that other fast serializers don't have: - Cross-language without IDL files (Rust ↔ Python/Java/Go) - Trait object serialization (Box) - Automatic circular reference handling - Schema evolution without coordination Happy to discuss design trade-offs. Benchmarks:…

Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

Hi HN! I'm building a JavaScript debugger called Wirebrowser. It combines network inspection, request rewriting, heap snapshots, and live object search. The main experimental feature is BDHS (Breakpoint-Driven Heap Search): it hooks into the JavaScript debugger and automatically captures a heap snapshot at every pause and performs a targeted search for the value or structure of interest. This reveals the moment a value appears in memory and the user-land function responsible for creating it. Another interesting feature is the Live Object Search: it inspects runtime objects (not just…

I'm sure folks here have seen pastebins a thousand times. There's no innovation left in this space – and that's kind of the point. When I wanted to self-host a pastebin, every option I found was too much. Git-based version control, OAuth, elaborate admin panels. I just wanted something I could deploy in under a minute with a CLI that actually works. So I built pbnj (yes, like the sandwich). What it is: - A minimal, beautiful pastebin with syntax highlighting for 100+ languages - One-click deploy to Cloudflare (free tier gives you ~100,000 pastes) - CLI-first: pbnj file.py → get a URL, copied…

Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…
