EINVAL: Valid solutions for invalid problems

Translations: PL

Hi. My name is Wojciech Siewierski, sometimes known as vifon. I am a software engineer and a UNIX sysadmin from Warsaw, Poland.

On this blog I’m going to write about various useful/funny/surprising/obscure ways to get things done. Or anything I will find particularly interesting, really.

If you’d like to contact me, I can usually be found on irc.libera.chat as vifon.
