Mix of ideas from various notes:

Designing SME network infra
Attacks: VLAN hopping, ARP poisoning, DHCP hijack, what else?
Terminal basics https://wiki.itcollege.ee/index.php/I253_Informatika_eelkursus
OpenCV: numpy arrays, blob detection, AR code recognition, tricks for performance boost
Prepping for G/FB interviews goto techlead: Systems design (kv store), Coding & algorithm (tail), Leadership, Linux internals
Building distributed systems (minio, mariadb galera, etc); Consistency models, critical write, critical read etc
blade servers in general: higher compute density, ILO management, backplanes, expansion modules, dell blades (standard AHCI is nice), hp blade
ZFS (FreeNAS, ZoL, dedup, compression, zfs send, encryption, fragmentation, datasets) - can't shrink pool, can't balance pool; benchmarks raidz1 vs raidz2 vs mirror - different workloads, read-write, read, write, mixed, random, sequential. ashift=12 atime=off failure recovery (it's automagical!)
Btrfs: Disable COW for MariaDB, postgres. Device add/remove, pool rebalance
10GbE networking (mtu 9000, mbuffer, aesni, intel/chelsio/etc chipsets, wiring, sfp modules, fibre optics, multimode/singlemode)
SATA, SAS, NVMe, multipath, GPT (?), nearline SAS, LSI chips & card models
Retro: vt220 review & fixup, nokia terminal, sun workstation review & solaris install, sun fire v240 setup, solaris install, ibm aix setup, ibm ps/2, sgi indy, crt beamer
CNC: pcb milling and preparation, wood milling, aluminium milling, x-carve vs stepcraft
nixie, VFD, old school display tech, numitron
OpenPGP/GnuPG https://gist.github.com/artizirk/d09ce3570021b0f65469cb450bee5e29 https://www.kernel.org/doc/html/latest/process/maintainer-pgp-guide.html
ssh certificates controlmaster, better client config
netcat, mbuffer, moving shit over network
log parsing: parallel, grep, awk, python, Go?
fileservers: SMB, NFS, MTU, crypto (or lack of it), ACL-s
container / deployment secrets managment
hashicorp is for enterprises, not really for self-hosting
