You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
In the previous article we explored how the Go runtime bootstraps itself — how a Go binary goes from the operating system handing it control to your func main() running. During that bootstrap, one of the first things the runtime sets up is the memory allocator. And that’s what we’re going to explore today. Think of…
My old 2016 MacBook Pro has been collecting dust in a cabinet for some time now. The laptop suffers from a “flexgate” problem, and I don’t have any practical use for it. For quite some time, I’ve been thinking about repurposing it as a guinea pig, to play with FreeBSD — an OS that I’d aspired to play with for a long…
For some reason, nobody's written about what it takes to crawl a big chunk of the web in a while: the last point of reference I saw was Michael Nielsen's post from 2012 .
FreeBSD 15 comes with a new bridging implementation which has native support for VLANs. They have also soft-deprecated the ability to have any layer 3 addresses on member interfaces which makes it behave like a real hardware switch. The net.link.bridge.member_ifaddrs sysctl controls this behavior and it will …
Most linux software just work on FreeBSD
Containers ran in production on FreeBSD thirteen years before Docker. So why does nobody talk about it?
This essay explores the cost of multitasking through computer science concepts like context switching and advocates for the focus found in single-threaded moments.
Cloudflare suffered a service outage on February 20, 2026. A subset of customers who use Cloudflare’s Bring Your Own IP (BYOIP) service saw their routes to the Internet withdrawn via Border Gateway Protocol (BGP).

Adventures with dry ice and RP2350 - how fast can it go?
Standard diffusion language models can't use KV caching and need too many refinement steps to be practical. CDLM fixes both with a post-training recipe that enables exact block-wise KV caching and trajectory-consistent step reduction — delivering up to 14.5x latency improvements
I’ve always wanted an ARM server in my homelab. But earlier, I either had to use an underpowered ARM system, or use Asahi which not only requires expensive Mac hardware but also slowed down in the past few years.
Buy an RTX 5090, the fastest consumer GPU money can buy, and you get 104.8 TFLOPS of FP32 compute. Ask it to do double-precision math and you get 1.64 TFLOPS. That 64:1 gap is not a technology limitation. For fifteen years, the FP64:FP32 ratio has been slowly getting wider on consumer GPUs, widening the divide between…
We are an exploratory species, just past the solar system now, but perhaps one day we will look back and call our galaxy merely the first. There are many problems to solve along the way, and today we will look at one very small one. How do we assign IDs to devices (or any object) so the IDs are guaranteed to always be…
If you compile your app for AVX2 and it runs on Windows ARM under Prism emulation, is it faster or slower than compiling for SSE2-4.x? I assumed it would be roughly the same — maybe slightly slower due to emulation overhead, but AVX2's wider operations would compensate. The
I want to make this clear in the first sentence because its biggest chance that people will read it – this article is entirely based on work done by Christian Hofstede-Kuhn (Larvitz) that wro…
Porting Linux to Apple Silicon
Wherein we make progress towards solving one of the most vexing problems of Computer Science — naming things.
News and information from Gentoo Linux
GPU code can now use Rust's async/await. We share the reasons why and what this unlocks for GPU programming.

I’m Sérgio, and I work with Web frontend code. Sometimes I write about it here.
Imagine you’re maintaining a native project. You use Visual Studio for building on Windows, so you do the responsible thing and list it as a dependency
Anthropic and OpenAI both recently announced “fast mode”: a way to interact with their best coding model at significantly higher speeds. These two versions of…
OpenSSL sucks. The BoringSSL and AWS-LC forks are Googled and Amazoned to death; they don't care about anyone but their own use cases. I can't remember ever having a good experience with software using GnuTLS. LibreSSL is incomplete... FOREWARD This post is about the experience of taking a leap of …
Waymo will begin fully autonomous operations with its 6th-generation Driver —an important step in bringing our technology to more riders in more cities. This latest system serves as the primary engine for our next era of expansion, with a streamlined configuration that drives down costs while maintaining our…
Terrace runs sensors attackers cannot tell from real targets. We see new attack sources first, record what they do, and ship the block rules while the attack is still running.
Invariably, it involves trying to trap electrons in increasingly complicated ways.
