Screenshot of text from claude.ai:

Docker Compose integration:

There's no native Nix support in compose, but the cleanest approach short of a script is using compose's build with a custom dockerfile that just calls out... actually that defeats the purpose.

Started using Claude exclusively instead of ChatGPT (for obvious reasons), and laughed out loud when I saw claude say "oh wait no my bad" in the middle of an explanation.

Anyone who made fun of the windows file copy progress dialog owes someone an apology. My rsync has been sitting at 95% for 12 hours and is still making solid progress copying to my new ZFS pool.

Had a "tiramisu danish" this morning in London and it was honestly one of the best pastries I've had.

With Ring, American Consumers Built a Surveillance Dragnet Ring's 'Search Party' is dystopian surveillance accelerationism.

If you still have a Ring camera, you may want to think about replacing it with something a little less Continental Panopticon.

The funny thing is that these drives look externally identical to another set that i bought from a different seller on ebay that worked perfectly. And they kinda sorta work when you plug them in, except you can't actually touch any data on them.

Today I learned that not only could an enterprise drive be formatted with 520 byte sectors instead of 512 byte sectors (causing linux to shrug and give up) but also it could have special vendor firmware. It's been an ordeal, but it looks like openSeaChest and sg_format are going to save this drive.

This OpenClaw thing is amazing. It helped me corrupt my database in a fraction of the time it would've taken me to do it by hand.

4TB drives are such a steal compared to what a 12TB+ drive sells for right now, but it only makes sense if you have a server that can fit a ton of drives.

If you've never played with server class machines, you'd never know some of the crazy stuff they can do. I learned today (from some drives I got on ebay) that multipath SAS is a thing. One drive connected to a single backplane talking to two HBAs. Like a little network for hard drives. Crazy

Incidentally, I think reasonable people can still differ about whether this counts as thinking or understanding, but frankly either possibility is weird. Either a machine can think and reason really well, or you can somehow solve very hard open math problems without thinking/reasoning/understanding.

I'm switching to Anthropic for an app I'm building because OpenAI doesn't have an IPv6 endpoint... in 2025.

Sorry, I'm not going to pay $45 a year extra just so I can have an IPv4 address to talk to your API.

If you just heard a really loud sigh, it's because I just saw the library book my son took home. It's about a kid who time travels to the distant past... to the year 1993

Feels strange cancelling my subscription to a VPS I used for some side projects, after being a customer for 20 years.

Now I feel really old.

Building a Debugger is now officially released!

It guides you through building a whole native x64 debugger from scratch, dispelling all the magic and teaching you a ton about operating systems as it goes.

Even if you don't care about building a debugger, you can read it to your cat.

I have a story about this. Arm kernel debugger would run the CPU at 100% when at an exception. Supposedly early WP hardware didn't have sufficient thermal protection so it could literally crash and burn.

I don't know if it ever actually happened, but I was told to be careful when debugging.

100% accurate. I saw Dawson's first law many times working on WinDbg. With a few of them discovered by Dawson. The rest were discovered by the SQL server team using thread/module counts beyond what any sane person would expect.

O(n^2) is the "works on my machine" of algorithmic complexity.
