Wow, what an excellent way of phrasing it. Give me more. Why "any movement is circular"?

Polish history is very colorful. The (rather thick, but reasonably impartial) recommended read on Polish history over centuries is Norman Davies's "God's Playground" https://en.wikipedia.org/wiki/God

I made an attempt to check: * shutdown(SHUT_RD): seem not to have _any_ side effects. you can totally still recv() on that socket. Kerrisk writes 61.6.6: "However if the peer application subsequently writes data on its socket, then it

Then there is a discussion about forcefully killing sockets :) * close(): socket will be lingering in background as usual * shutdown(SHUT_RD): no network side effect, discards read buffer * shutdown(SHUT_WR): equivalent to FIN SO_LINGER soc

On i7: > AVX2 code is faster than the dedicated instruction for input size 512 bytes and larger The difference is indeed tiny. Still - it's very cool the generic AVX2 code can beat the instruction burned in the silicon!

There is more! You can be _faster_ than __builtin_popcount()! Wojciech Muła did an excellent SSSE3 implementation: http://0x80.pl/articles/sse-popcount.html My understanding is that the set-up time is slower than the P

Digging more about IPv6 representation: - It's possible to stick "::" in many places - It's possible to have :0000: before or after "::" - leading zeros (:0001: is the same as :1:) - "Text Representation o

Parsing IPv6 also requires some thought! Consider 0000:0000:0001:0002:0000:0000:dead:beef - 0000:0000:1:2::dead:beef - ::1:2:0000:0000:dead:beef - ::1:2:0:0:dead:beef - ::1:2:0:0:222.173.190.239 - 0:0:1:2::222.173.190.239

Author here. For one - read the article! BPF was originally used purely for tcpdump, but has been re-used since then. Nowadays it's used in surprising number of Linux subsystems. eBPF allows us to do things previously impossible - you
