I’m working with ontologies (BFO, OBO-Foundry), semantic-web/linked-data (mainly with RDF4j but also with Jena). In term of database, I favor PostgreSQL and stay away from schema-less nosql DBs except: when I need K/V caching then I use Redis or when I need advanced text-search where I’m going to use Solr and ElasticSearch.
In term of server management, I can currently do everything from cable management, to server installation, networking etc. For isolation, I use Docker, LXC/LXD and KVM/QEMU libvirt depending on the situations and needs. I deploy with Ansible. I watch the servers with Prometheus and Grafana.
I worked with Martin Peres on a program that allows the use of OWON oscilloscopes (we only tried with the 7102, but it should work with others) under GNU/Linux (and it works!): https://github.com/bjonnh/owon-sds7102-protocol
Some other things I may sometimes talk about here: Software and hardware development for research tools: microcontrollers, 3d printing, laser cutting, CAD design (openSCAD, Blender), retrofitting, adaptations, reverse engineering , ç̡̛̱͉̥͎̝̳͇̲̲̼̟̞̬͐̅ͦͭ͛̀ͥh̡̙͓̦̪͍̲̺̲̔͗̔̐ͩ̈̅ͭͣ͘͢ą̜̦̜̝̞̬̬̗̦̳̠͕̠̻̗͌̔͋̐́ͧͤ̾͊̄͆̇͑̾ͬ̉ͨ́͘͠ơ̬̬̺͔͇͙̤̺̌͊ͭ̈͒ͥͪ͘͢s̸̵̛̝͚͎̹̤̻͚̱̲̺̥̜̮͇͓ͮͥ͛̊͌̋ͩ̈ͫ͜ͅ.̸ͥ̅̉ͣ̊̅ͮ̆̒̇̓ͭ͏͎̪̖͈̠̣̮̝̮̪̥͎̫̩̦ͅ
