Evil job interview puzzle: Write a piece of code, that will "flush()" a network socket on Linux. It should wait (block) until all data from a TCP socket are transmitted and accepted. (hint: this is almost impossible with POSIX sockets API)

Got 64-bit Debian running on my new rpi4 (a lot harder than it ought to be), so I've accomplished one out of about a dozen tech things I wanted to do over the holidays. Still, better than zero.pic.twitter.com/gAXvftYMGo

It's super hard to do a custom programming language runtime without relying on C. OS Kernel depends on the userspace to have C semantics! Example: https://marcan.st/2017/12/debugging-an-evil-go-runtime-bug … Here OS assumes the user has a large stack. Basically - OS requires C in userspace, whether we like it or not

Brilliant articles from
@thatcks about errno and Linux ABI. https://utcc.utoronto.ca/~cks/space/blog/programming/GoCLibraryAPIIssues … https://utcc.utoronto.ca/~cks/space/blog/unix/CLibraryAPIRequiresC … There is a subtle contract between OS, the Libc, and the programming language runtime. From signals and stack handling (red zone), exception unwinding, to errno and TLS.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

A gem I was totally unaware of. Since kernel 4.6 an unprivileged user can create "user namespace" in which a first process has _all_ capabilities. For example you can create network namespace. This sounds super useful for unprivileged network testing. http://man7.org/conf/meetup/understanding-user-namespaces--Google-Munich-Kerrisk-2019-10-25.pdf …pic.twitter.com/pcHrA8S5QK
