Programming

I got an email from Vercel urging to upgrade Next.js based project 3 days ago. POC was published 2 days ago. Today I've checked my logs and I could already see attack attempts.

It started with a perfectly good and running kubernetes cluster hosting fediverse applications at keyboardvagabond with all the infrastructure and observability that comes with it. Then I made a simple networking fix.

I’ve been working on a "Linux Inside Out" series and wrote a post that might interest folks here who like low(ish)-level / OS internals.

The idea is to dissect the components of a Linux OS, layer by layer, and build a mental model of how everything fits together through experiments.

The first part is about the kernel, in the post I:

• take the same kernel image my distro boots from /boot
• boot it directly with QEMU (no distro, no init system)
• watch it panic
• write a tiny Go program and use it as PID 1
• build a minimal initramfs around it so the kernel can actually start our process

The goal isn’t to build a real distro, just to give a concrete mental model of:

• that the Linux kernel is just a compressed file, you can boot it
• without anything else
• what the kernel actually does at boot
• how it hands control to userspace
• what PID 1 / init is in practice
• what is kernel space vs user space

I’m the author, would be happy to hear from other devs whether this way of explaining things makes sense, and what you’d add or change for future posts in the series.

Hope you find it useful.

TL;DR: I spent a solid month “pair programming” with Claude Code, trying to suspend disbelief and adopt a this-will-be-productive mindset. More specifically, I got Claude to write well over 99% of the code produced during the month. I found the experience infuriating, unpleasant, and stressful before even worrying about its energy impact. Ideally, I would prefer not to do it again for at least a year or two. The only problem with that is that it “worked”. It’s hard to know exactly how well, but I (“we”) definitely produced far more than I would have been able to do unassisted, probably at higher quality, and with a fair number of pretty good tests (about 1500). Against my expectation going in, I have changed my mind. I now believe chat-oriented programming (“CHOP”) can work today, if your tolerance for pain is high enough.

Biggest WTF news I've read today. I'm not a web dev so this doesn't affect me, but this is bizarre.

We get a closer first look at what's around the corner for AI coding tools, and make Bun better for it

This incredibly popular tool is now going to merge with an AI company and shift gears to be turned into some forced AI hype machine. Yipee! Exactly what all the devs were hoping for! /s
