Crawling a billion web pages in just over 24 hours, in 2025
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 .

Using the new bridges of FreeBSD 15
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 …

Fix your tools
Last week I had to diagnose a bug in an open source library I maintain. The issue was gnarly enough that I couldn’t find it right away, but then I thought: if I set a breakpoint here and fire up the debugger, I will likely find the root cause very soon… and then proceed to mercilessly destroy it! So I rolled up my…

Attention Media ≠ Social Networks
When web-based social networks started flourishing nearly two decades ago, they were genuinely social networks. You would sign up for a popular service, follow people you knew or liked and read updates from them. When you posted something, your followers would receive your updates as well. Notifications were genuine…

Why is Claude an Electron app?
If coding agents make native ports cheap, why does Anthropic still ship Claude as an Electron app? Because code is cheap but maintenance isn’t.

How Taalas “prints” LLM onto a chip?
A startup called Taalas , recently released an ASIC chip running Llama 3.1 8B (3/6 bit quant) at an inference rate of 17,000 tokens per seconds. That's like writing around 30 A4 sized pages in one second. They claim it's 10x cheaper in ownership cost than GPU based inference systems and is 10x less electricity hog…

Cord: Coordinating Trees of AI Agents
AI agents are good at doing one thing at a time. Give Claude a focused task and it performs. But real work isn’t one task. It’s a tree of tasks with dependencies, parallelism, and context that needs to flow between them.

Anger over ICE connections and privacy violations is fueling the sabotage. PLUS: 10,000 drivers call on Uber to repay stolen wages, a man is arrested at a public hearing about a data center and more.

Don't create .gitkeep files, use .gitignore instead (2023)
Git only tracks files, not directories. It will only create a directory if it contains a tracked file. But sometimes you need to “track” a directory, to ensure it exists for fresh clones of a repository. For example, you might need an output directory called build.

I recommend turning Dependabot off and replacing it with a pair of scheduled GitHub Actions, one running govulncheck, and the other running CI against the latest version of your dependencies.
