I guess I gotta write one about CPUs now ;)


No problem really, I think most people want to bootstrap quickly from the low level into the higher abstractions that they care about, few people want to stay down in the cpu itself.


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!


I did a traceroute to how-did-i-get-here.net, and it went through a completely different network to the one they reported for the reverse.


Yup. Those paths are cached bidirectional.


check the html :)


Nice!


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.


I love cpu.land! Thanks for creating such a fun resource.


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


Thanks for helping!!!


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