about

Linux-minded technician and part-time philosopher. I fix computers for work and break my own for fun.

These days I'm doing level II support at Ace Computers, mostly custom-built systems, Linux, and HPC environments.

Also: birds, anime, piano, and thinking about things way too much. The alias is a bird that hovers perfectly still while watching everything below it. Felt accurate.

things i like

  • birdwatching, nature, slow mornings
  • vinland saga, steins;gate, frieren
  • piano, meditation, journaling
  • marcus aurelius, the tao te ching, philosophy in general
  • linux ricing, FOSS, vim, CTFs, terminal aesthetics, catppuccin (obviously)

NAME

kestrel - small falcon, hovers perfectly still, watches everything below

SYNOPSIS

kestrel [--alias localhost | 3hz | naftali] [--quiet]

DESCRIPTION

An alias. The person behind it goes by Naftali: Linux-focused technician, ESCP certified, top 30 globally in picoCTF 2019, now level II support at Ace Computers. The real-name stuff lives at mitchellberg.org.

WHY KESTREL

A kestrel is a small falcon that can hover perfectly still in the wind while it watches the ground. I've always liked that. I'm really into birds too, so the name kind of picked itself.

ALIASES

localhost
current main. yes, the irony is intentional.
kestrel
see above.
3hz
older, still mine. used in security contexts, like helping out as a security-minded community member on Hytale. low frequency, quiet signal.
naftali
my hebrew name, used by people who know me.

STATUS

Doing level II support at Ace Computers, focused on Linux systems and HPC. Not looking for a new role. Résumé and contact details are at mitchellberg.org.
