When someone tells you to have a laser focus, please remember not to stare directly into the laser as that may cause a permanent lack of focus.

This makes me really happy.

Everyone at #FOSDEM is touting their "single binary", I guess what we need now is a binary dating site

Why resolving two names in a GUI program is hard ;
A summary of available name resolution APIs on Linux and why a new one is needed by Petr Menšík

getaddrinfo is blocking. getdns and adns are DNS-specific. systemd-resolved is systemd.

GUI applications want to wait for events, not to have blocking calls.

So, the parser is very fast but also very specialized. If IETF adds things to the zone file syntax, the parser is doomed.

First step to speed parsing: drop Lex and Yacc (too slow and too general for DNS zone file parsing).

Next step, preventing the CPU pipeline to stall (bubbles - NOP - stall the flow.)

.com is 160 Mdomains and 24 GB.

@pb's eu.org is almost as large (this was a troll)
