Anti-DDoS Firm Heaped Attacks on Brazilian ISPs

A Brazilian tech firm that specializes in protecting networks from distributed denial-of-service (DDoS) attacks has been enabling a botnet responsible for an extended campaign of massive DDoS attacks against other network operators in Brazil, KrebsOnSecurity has learned. The firm's chief executive says the malicious activity resulted from a security breach and was likely the work of a competitor trying to tarnish his company's public image.

How an Oil Refinery Works

How an Oil Refinery Works

Though wind and solar continue to carve out larger and larger shares of world energy supply, the modern world still runs on petroleum, and will continue to do so for the foreseeable future.

After a busy March, April was a little quieter. But don’t worry, I still have a bunch of little links for you to click on. Things I published GitHub’s uptime hasn’t been great recently. Even though I dislike the Microsoft subsidiary, I wrote “In defense of GitHub’s poor up...

LLM 0.32a0 is a major backwards-compatible refactor

I just released LLM 0.32a0, an alpha release of my LLM Python library and CLI tool for accessing LLMs, with some consequential changes that I've been working towards for quite a while. Previous versions of LLM modeled the world in terms of prompts and responses. Send the mod...

Raspberry Pi Connect may control Windows soon

Support for remote controlling Windows PCs may be added to Raspberry Pi Connect, Raspberry Pi's free remote access service.

Raspberry Pi Connect controlling a Windows 11 PC

When they announced Pi Connect in 2024, I speculated the service was launched in response to RealVNC's sluggish adoption of Wayland, leading to Pi users lacking a solid remote access solution after Pi OS 12 'Bookworm' was launched.

The service was helpful for those who had one or more Raspberry Pis to access, but the Pi Connect daemon didn't run on Windows or macOS at the time, so a true competitor to RealVNC (at least for basic use cases) it was not.

Collective Speed Is Not the Summation of Individual Speed

I’ve been thinking about speed which is why Chris Coyier caught my attention in his latest piece discussing how AI might be 10✕ing the speed with which we code, but it’s not making our software 10✕ better: Faster individuals don’t make a fast company My mind immediately we...

Quoting Matthew Yglesias

Five months in, I think I've decided that I don't want to vibecode — I want professionally managed software companies to use AI coding assistance to make more/better/cheaper software products that they sell to me for money.
