Today, we are excited to announce a new API in Cloudflare Workers for creating outbound TCP sockets, making it possible to connect directly to databases and any TCP-based service from Workers
I recently changed jobs and found myself in a position where I would need to do a lot of work on remote machines. Since I am Emacs user, the most common way to do this is using TRAMP (Transparent Remote access, Multiple Protcol). TRAMP is an Emacs package that let’s you treat a remote host like a local system, similar…
LLM-based agents can do a lot of tasks. Or, at least, they can appear to do them. For example, they write code, summarize papers, plan trips, and fill in forms. If you ask one for a probability or a confidence score, it will give you one of those too. I have seen many agent designers use LLMs to generate confidence…
This article describes a project of mine that has been laying around my harddrive in a rough draft for a couple of months. I want to continue developing it at some point, but can’t right now …
The Closure Compiler was originally released, in Java, back in 2009 . Today, we're announcing the very same Closure Compiler is now available in pure JavaScript , for use without Java. It's designed to run under NodeJS with support for some popular build tools.
Unix counts time as seconds since the epoch. Seems straight forward. What could possibly go wrong?
Announcing a major revision of the Go API for protocol buffers.
DNS servers often have to convert DNS names to their canonical lower case form. BIND has to do so a bit more than most because it tries to preserve the case of DNS names rather than canonicalizing them.
How I wrote GoAWK, how I tested it, and how I measured and improved its performance.
I love the Kate Text editor. I use it for pretty much all the programming projects I do.…
Our algorithm has the peculiar property that, roughly speaking, the longer the pattern is, the faster the algorithm goes. Furthermore, the algorithm is ``sublinear'' in the sense that it generally looks at fewer characters than it passes. The algorithm is described in
I'm finishing a new edition of my Refactoring book. Here's details and periodic memos about my work.
rwasa is our full-featured, high performance, scalable web server designed to compete with the likes of nginx . It has been built from the ground-up with no external library dependencies entirely in x86_64 assembly language, and is the result of many years' experience with high volume web environments. In addition to…
Did you know that Go lets us provide executable code examples as part of our documentation? It’s pretty neat. Let’s take a tour of this useful feature and see how it works.
It seems no matter how long I work with the command line, every once in a while I find handy utilities I've never encountered before. Most people have heard about the bird coreutils , that's where utilities such as echo , cat , and others come from. But did you know about moreutils ?
GPU code can now use Rust's async/await. We share the reasons why and what this unlocks for GPU programming.
A long division story
Unlike the Apple I, the Apple II was fully assembled and ready to use with any display monitor. The version with 4K of memory cost $1298. It had color, graphics, sound, expansion slots, game paddles, and a built-in BASIC programming language.
Mistakes and lessons from a real-world feature performance optimizations: from API usage to advanced data structures, from bit hacks to CPU-friendlier code.
How I Built a Vector Map from Scratch
One of my favorite game jams is the legendary Js13kGames competition, where participants have one month to make a web browser game that fits in a 13 kilobyte zip file. To put that into perspective,…
Updated (February 07 2013): If you enjoy this article, you may also find the more academically-inclined article The Impact of Meta-Tracing on VM Design and Implementation interesting.
This year, the YJIT team and I have gotten a paper accepted at MPLR 2023 (Managed Programming Languages and Runtimes), which is now freely available through ACM open access. The paper, titled “Evaluating YJIT’s Performance in a Production Context: A Pragmatic Approach”, goes into details of the strategy taken to…
Fuzz testing decades-old software can turn up some curious behaviors
The official home of the Erlang Programming Language
Python is my favourite programming language. Since I discovered it in 2004, programming in Python became my favourite hobby. I've tried to l...
Git was born from the collaboration problems in the Linux kernel. Nearly a decade later, new problems arose when Kubernetes (the operating system of the cloud) brought open-source collaboration to a new level.
