Products that do what I Built 0xFast Stream – 100x Faster Ethereum Block Downloads does
Getting web3 data out of Ethereum nodes or node services is excruciatingly slow (at least days if not weeks). I had wanted a way to just download the blocks quickly since I started exploring the web3 space. Took me a bunch of trial and errors to get to a way where I can parse all the blocks since genesis within 12 hours. But, instead of moving on to the next thing, I put this service together over the last few days, so everyone can benefit.

Excited to showcase 0xFast to HN! Built using a new indexing system designed for Web3 data, 0xFast outperforms the most popular web3 API platforms, while also being 3x cheaper.

Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

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 built this over the weekend. Any feedback is appreciated. Please note you will need a WebGL enabled browser. Thank you for checking it out. --UPDATE-- HN Traffic is strangling earthbit. There is sporadic downtime due to the web services I am using, if no transactions appear after a few seconds, then please try again in an hour.

I founded the first blockchain certificate of deposit. I'm surprised that it became so popular so fast, I hope it doesn't cryptokitties the network. The marketing looks like a scam.

I've been working on Fast LiteLLM - a Rust acceleration layer for the popular LiteLLM library - and I had some interesting learnings that might resonate with other developers trying to squeeze performance out of existing systems. My assumption was that LiteLLM, being a Python library, would have plenty of low-hanging fruit for optimization. I set out to create a Rust layer using PyO3 to accelerate the performance-critical parts: token counting, routing, rate limiting, and connection pooling. The Approach - Built Rust implementations for token counting using tiktoken-rs - Added lock-free data…

Hi everyone! I'm one of the co-founders of Wonder Interactive, the company behind the SimplyStream platform. We've spent the last several years building out a browser-based platform for developers to deploy their native applications to the web, and today we're showcasing demos of our integration with Unreal Engine. Here are a few highlights: SimplyStream File System for seamless asset streaming Tiny WASM core, full engine power Multi-threaded WebGPU for native-like performance Please see our website for more information such as additional features, pricing, etc.

Hey HN! I have been working on Ant for a while now, would love to share around now. What is Ant? It's my JavaScript runtime, built from scratch over many hours of work. Much effort has gone into keeping the binary size small, around 9MB at the moment (6.5 MB with -Os). On my M4 Pro, the hono coldstart bench (examples/npm/hono/bench-coldstart.js) lands around 5ms, about 2.4x faster than bun, and 5.8x faster than node. To keep things small, the engine ("Ant Silver") is hand-written, not a wrapper around V8/JSC/SpiderMonkey. The JIT is still a work in progress but it…

Hey HN, we’re Eliza and Xin. We’re working on Hurry, an open source drop-in tool that adds distributed build caching to Cargo with (almost) zero configuration. Wherever you run cargo build, you can run hurry cargo build instead, and expect around 2-5x (our best benchmark is 22x) faster builds. We built this because we were dissatisfied with the current build caching options available for Rust. Buck and Bazel require learning a new tool. GitHub Actions and swatinem are too coarse-grained (either the whole cache hits, or none of it does) and finicky to debug, and cargo-chef and Docker layer…
