I love the act of writing code, it clicks well with me. I love the feeling of my brain solving problems, figuring out how something works, and then finally understanding it. I love debugging. I love having built something that people love, solely wrought by my own fingers.

I got into programming because the act of spinning a web of code just feels like what I'm designed to do.

Vibe coding definitely has some of that, but it feels so detached from any understanding of the computer itself. I feel like I'm bossing someone around — and I would never want to be a non-coding manager. I'm curious, how/why do you feel so different?

(Obviously the financial side is stressful too, but I feel like I'm in a good spot to figure that out either way.)

I've seen a lot of posts like this one, but this is the first to encapsulate how I feel so well.

Honestly, I don't really know what to do. I spent my whole life (so far; I'm still very young) falling in love with programming, and now I just don't find this agent thing fun at all. But I just don't know how to find my niche if using LLMs truly does end up being the only way for me to build valuable things with my only skills.

It's pretty depressing and very scary. But I appreciate this article for at least conveying that so effectively...

Anecdotally, I've run a bunch of traceroutes and reverse traceroutes to different locations and they tend to follow the same AS paths — although sometimes the traceroute will surface more routing through your ISP (especially from college networks). In general you are correct, though, and I would love to explain more about hot-potato vs. cold-potato (and other interesting routing decisions) in the future. Either way, the results the reverse traceroute provides are good enough for the purposes of explaining the internet, IMO!

This is awesome! To anyone interested in learning more about this, I wrote https://cpu.land/ a couple years ago. It doesn't go as in-depth into e.g. memory layout as OP does but does cover multitasking and how the code is loaded in the first place.

Had the pleasure of helping rack drives! Nothing more fun than an insane amount of data :P

Interesting. Got 19/20 too, and also missed #14!

i don't think it's your fault. spotify's entire website is down for me right now, i'm getting "upstream request timeout" and "upstream connect error or disconnect/reset before headers. reset reason: overflow" just trying to load the homepage. this happens every couple of months.

if only this went into where the ocaml escape came from :)

This is pretty cool. Worth noting that Git does not actually only store full copies of files every time you make a change, this article I found does a really good job at explaining Git's packing: https://gist.github.com/matthewmccullough/2695758

CSS transforms!

    transform: rotate(-2deg) skew(-2deg);
    transform-origin: bottom left;

"Reliable" may have been crufty wording but I did get more responsive results using it. MTR uses ICMP by default. Definitely want to do a hybrid thing in the future though!

Ooh, that's compelling. I wonder how that would work for an actual traceroute.
