Only in case you are interested in the original source, of course. If you like the copywrited version of it, you can go to techdirt :)

Safety I Learn from Errors, Safety defined by absence,Reactive approach, Understanding what goes wrong, Accident causation models, Avoidance of errors, Reducing losses

Safety II Learn from successes, Safety defined by presence, Proactive approach, Understanding what goes right, Repeat what goes right, Enforce successful behaviours, Create new processes based on successful behaviour

If anything, think long and hard about this: "Post-accident attribution to a ‘root cause’ is fundamentally wrong." It's a true statement. If you truly understand this sentence, you have mastered Safety II to the level that a light bulb will come on, and you won't be able to un-see it. This light bulb is a curse, a beautiful curse.

See slide 18. It was really nice to see him win. I have always been a huge fan of symmetry breaking, CryptoMiniSat (that I develop) had a symmetry breaking system, BreakID (which is _way_ slower than Markus' satsuma), in it for many years now.

What is going on over there? No process, no oversight, just YOLO? Super-scary, because it means other stuff that we don't see is likely to be done in a similar manner.

The issue is, the people holding the stamps (and believe me, they ARE stamps, with ink and all) are in charge, and are VERY reluctant to give up that comfy job. Zero accountability, too, since once you are a government employee, it's incredibly hard to get fired. So they stall the process, forever, without any reprecussions.

I am all for having and caring about process and dealing with everyone equally. That's why I live in Germany and not in Eastern Europe where often some money under the table is the only oil in the machine. No such oil in the German machine, thankfully. But it's infuriatingly slow, because bureaucrats are in control and will never willing give up that control.

It's time to be serious about this. Unacceptable.

Beyond the soldering iron, my recommendations that are not too obvious at first sight:

* solder paste (verrrry useful, just get it, and use it)

* something to purify air that _pulls_ it (a reverse fan) with a carbon filter (~30 USD)

* magnifying glass, hopefully attached to a ring of LEDs + a stand so you can see what you are doing (30-60 USD)

* solder sucker, hopefully automated (5 USD non-automated, 80 USD+ automated)

ELRS (radio), Ardupilot (Flight Controller), EdgeTX (Radio OS), and Mission Control (Ground Station SW) are serious tools used by many in the hobby. Them being open means there's a lot of competition and a lot of features. But also not amazing UX :)

It seems like the best students/people eventually end up doing CS research in their spare time while working as engineers. This is not the case for many other disciplines, where you need e.g. a lab to do research. But in CS, you can just do it from your basement, all you need is a laptop.
