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...

I guess I gotta write one about CPUs now ;)

check again!

somewhat better now! added a bit more concurrency. lesson learned: use tokio next time

It's like when your uncle squeezes you at Christmas. You're glad to see him again, but it's just a liiiitttleee... too... much... for... your... lungssss,.,.,.,

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!

check the html :)

oh yeah i saw this! newer than the website though :)

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.

+1, love it

BGP looking glasses are very fun, although a bit of a different concept.

And WOAH, that's really interesting about TTLs. Thanks for sharing! That's awesome and terrifying!

1. ICMP seemed a lot faster / more reliable, but you're right that UDP does sometimes bring out better results. Something I want to do is make it use a hybrid approach — sending both ICMP and UDP packets and using the best of both.

2. Wayy ahead of you, check for HTML comments :))

TY, will read! I touched on this duality in the article actually :)

Oh, thank you, I'll buy a copy! I thought Arrival was a fun movie

Yeah, there is actually a whole section about this in the article! Called "Front to Back, Back to Front".

tl;dr in my experience the networks traversed are usually very similar, and the content is relevant and interesting either way around

Should work a little better now! It's still chugging, but I made the rest of the article load (although now it's a bit janky when you have JS disabled, but not much I can do)

I KNOW, right?! It's perfect.

Shouldn't have anything to do with Enhanced Tracking Protection, but my server is buckling under the traffic pressure! I'm working on it, maybe check back in 40m or so (SORRY!)
