Garbage Collection for Systems Programmers Let’s talk about one of the most performance-sensitive programs you run every day: your operating system. Since every speedup gives you more computer to compute with, an OS is never fast enough, so you can always find kernel and driver developers optimizing the bejesus out of their code.

JavaScript Visualized: Promise Execution Due to its easi of use, and its forgiven model, promise remain an unclear? should I use return Promise<Value> or, return Promise.Resolve(value). all of that. Let look deeper to understand their execution model.

Hacking our PostgreSQL driver to get more out of Amazon RDS performance insights In the process of improving Knock performance, Knock engineers found ourselves in the weeds hacking our Postgres driver, and we wanted to share some fun learnings we’ve gathered so far.

Running a Raspberry Pi with a read-only root filesystem Many applications that run on Raspberry Pis and similar single-board computers — for example, environmental data loggers that report to a central database server — don’t really need to store any state locally on the Pi’s SD card. This means you can run the Pi with a read-only root filesystem, which will dramatically increase the...

Fifty Things you can do with a Software Defined Radio As a software engineer, I like to tinker around hardware projects, physical thing that you can touch, and show to our faimily. Radio is fastinating because there are many valueable information being pass around. You can listen to airplane communication, track aircraft via ADS-B, you will write some code to decode the signal and...

GPT in 500 lines of SQL It just proves that if you want something done right, you have to do it yourself. Encouraged by this optimistic forecast, today we will implement a large language model in SQL.

How Figma’s databases team lived to tell the scale I’m honst everytime I get into Figma, I’m frustrated and think how everyone using them? The UI is so clunky, I always have to make sure I don’t accidently move something. But anyway, they operate at massive scale and today they share the story they migrate and shard their database.

maxtext a high performance, arbitrarily scalable, open-source, simple, easily forkable, well-tested, batteries included LLM written in pure Python/Jax and targeting Google Cloud TPUs. MaxText typically achieves 55% to 60% model-flop utilization and scales from single host to very large clusters while staying simple and “optimization-free” thanks to the power of Jax and the XLA compiler.

pgzx There are already tool to help write Postgres extension with Rust such as pgrx. Now we can do with Zig. After the last 2 years working with Rust, I feel like it’s such as great language that is truely innovative compare with other, but there is still room for a low level language that isn’t too strict such as Zig. Using zig to...
