techman9 | 5 years ago | on: Why do we use the Linux kernel's TCP stack? (2016)

This is super useful! I've been hacking recently on qdisc classifiers, and trying to set a filter up with BPF, but there's a paucity of documentation on the subject. The tc tools are sorta documented here (https://man7.org/linux/man-pages/man8/tc-bpf.8.html), but it's quite hard to find docs on the underlying syscalls and the behavior of `bpf_prog_type_sched_cls`.

I bought a copy of BPF performance tools to learn more about the BPF interface, and it's really useful but quite focused on performance! I wish there was a resource of similar depth and breath about eBPF for classification/XDP.

techman9 | 5 years ago | on: The Case for Dumping the Electoral College

I do wonder whether the electoral college system somewhat insulates the US from election tampering or voter fraud. The current system disaggregates election certification to the state level, which is then made official by a discrete vote of the electoral college. For instance, if Donald Trump wants to claim that the election was rigged or tampered with, it's sort of moot as it's ultimately up to the state electors.

It feels like in the face of this, it's very hard for one candidate to dispute the election, as it's ultimately resolved by electoral vote. If we were to change the system to one based only a national first past the post poll, even one certified by vote totals from individual states, I wonder how you'd ensure an impartial certification of the final result.

Can you explain a bit more more about why you believe Delaware is the proffered place to register a corporation?

> That said, I didn’t want to mislead people. So we chose to be clear to them that there is a technical term; it’s just not going to be important for the rest of the content.

My understanding was that GDPR requirements apply to all citizens of the EU regardless of where the company is located. Someone else can chime in if that's not accurate!

Oh my god. And Starcraft, and Axis and Allies, (original) DOTA. I was even a WOW player back in the day before I got fed up buying expansions. Man, the hours of productive time I wasted...

I don't know. I grew up in the XP era and I played a lot of brainless games (3D pinball was where it was at) and read a lot of mindless Wikipedia articles as a kid. But then I got curious about how it all worked behind the scenes.

Maybe I'm too optimistic, but my hope is some of that inquisitive spirit hasn't been totally quashed. It's too depressing think that kids are not still discovering the internet as a virtually boundless repository of human information and a fascinating set of technical problems.

I credit much of my current aptitude with (and interest in) computers to getting to use one throughout my childhood with no restrictions. I understand it can be nerve-wracking for parents ceding that much control to children, but I think children are both smarter and more self-disciplined than we give them credit for and I think digital free range can build independence in the long run. Maybe my opinion will change when I have kids of my own someday. Who knows.
