Improve startup time by making the classes of an application instantly available, in a loaded and linked state, when the HotSpot Java Virtual Machine starts. Achieve this by monitoring the application during one run and storing the loaded and linked forms of all classes in a cache for use in subsequent runs. Lay a…
Division is quite an expensive operation. For instance, latency of the 32-bit division varies between 10 and 15 cycles on the Cannon Lake CPU, and for Zen4 this range is from 9 to 14 cycles. The latency of 32-bit multiplication is 3 or 4 cycles on both CPU models.
The ride is coming to an end. The experiment is done. We tried, but we admit defeat. Four years ago we started adding support for an alternative HTTP backend in curl. It would use a library written in rust, called hyper. The idea was to introduce an alternative implementation of HTTP internals that you could ……
What did you do at work today? How about last week? I spent a couple of days in quarterly business reviews, and wrapped up yearly planning activities for AWS Data Exchange and AWS Marketplace. I also added some unit tests to a project that I am onboarding into.
A popular data-oriented design pattern is a Struct of Arrays. Is an Array of Enums also useful? Yes! But let’s do a refresher on struct of arrays (SoA) first:
An interactive introduction to Turing machines, the theoretical foundation of modern computing.
Practical guidance from Anthropic on building reliable AI agents, from simple composable patterns to fully autonomous systems.
A deep dive into how I use types to the fullest
How to handle and report errors effectively in Rust applications is a common question. This blog shares our experience organizing variant types of Error in a complex system like GreptimeDB, from how an error is defined to how to log the error or present it to end-users. Such a system is composed of multiple components…
Bill Caputo , through repeated conversations we've had, has convinced me of something very surprising. It was something that changed the way I think about the world, and how I do my job.
I had never met Randal Schwartz before, but when I reached out to him about contributing to year 25 of the Perl Advent Calendar, he immediately agreed. This year I wanted to try some new things and Randal suggested giving a Perl-specific talk which he had given once before, but which was lacking in recording quality…
Java has many features that make it well suited for large, long-lasting projects. But I find it surprisingly good for small tasks as well. Recent language features make it even better. The killer features are compile-time typing and great tool support.
Meta has been on a years-long undertaking to translate our entire Android codebase from Java to Kotlin. Today, despite having one of the largest Android codebases in the world, we’re well pas…

Lessons learned from our challenges reducing LLM output: Discover everything that went wrong when trying to make our models say less.
Welcome to Waqas' blog
Previous update: An explanation of 3d projection mathematics (under Road Basics) and analysis of Activision's Enduro (under Case Studies)! Thanks to everyone for all the e-mail! Keep it coming :) Sorry, I can't answer questions about when I'll post source code, but I'm always happy to answer anything else about these…
Handling errors in Go is simple and flexible – yet no structure! It’s supposed to be simple, right? Just return an error , wrapped with a message, and move on. Well, that simplicity quickly turns into chaotic as our codebase grows with more packages, more developers, and more “quick fixes” that stay there forever…
I was recently made maintainer of the json gem, and aside from fixing some old bugs, I focused quite a bit on its performance, so that it is now the fastest JSON parser and generator for Ruby on most benchmarks.
Learn about Conflict-Free Replicated Data Types, Yjs, and how we built a collaborative, real-time playground in a web browser.
Hi, I'm Peter Bex, a Scheme and free software enthusiast from the Netherlands. See my user page on the CHICKEN wiki or my git server for some of my projects.

A deep dive into Rust’s vec::Drain and its Drop implementation as an example of how ownership prevents subtle bugs—memory and otherwise!
After almost two years of work, we are happy to announce the release of Xfce 4.20.
I was honored to present a talk on Ruby concurrency at RubyConf 2024. It represents a high-level distillation of much of my writing and research over the past year. The conference itself was great, and presenting was such a fun experience. Here is the talk, titled “In-Depth Ruby Concurrency: Navigating the Ruby…
