hey hey, this is exactly what happened to my engineering career right here.
"This code will never be used."
"Oh, ok." proceeds to write garbage to test out various features and different ways of doing the same thing
"Hey, this code is garbage and lacks consistency. Lets show it to everyone to warn them about this guy. We won't mention it until letting him struggle a couple years, but make sure he doesn't get any interesting work."
Every job I've applied for that required any level of physical work had "must be able to lift 50 lbs" as a requirement. It's a little heavier than a step ladder, bags of potatoes, flour, cement and gravel are typically in that range as well. It's not an unreasonable requirement. You typically won't lift them overhead, but floor-to-shoulder is a very common lift.
Extra fun fact about tinkering: The air gap in the transformer means that your GFCI won't detect a ground fault, and your circuit breaker won't detect a short because as far as the mains line is concerned, there is nothing wrong with the circuit.
This doesn't happen under normal operation, because the chassis allows for a short and/or a ground fault. But when you take that chassis off, and especially when you take the transformer out, you're putting yourself into a life threatening situation.
Much of my learning was on vacuum tube technology (often of the HV transmitting kind) and almost invariably anode supplies etc. are isolated from the mains so relying on ground-fault detection is, as you say, a waste of time. Actually, a microwave oven is a high voltage vacuum tube (magnetron) transmitter and should be treated as such.
My experience has been that it's easy to become careless and blasé through familiarity and that's when nasty things happen.
Every time I've been zapped (and it's been many) it's been through carelessness. Fortunately, most of those shocks were of the 250-400V DC variety inside a chassis where it was only my hand that was between the 'hot' point and earth.
Nevertheless, I've also had a few very close shaves and I shudder even now whenever I think about them. One was on top of a microwave tower in a rainstorm whilst adjusting a klystron that had slipped outside its AFC/S-curve range. It was fed with a -1500V (on the heater circuit which one usually thinks of as being at ground potential) and the other supply was +800V at the collector. Water was everywhere. To make matters worse, at the time I was standing on wooden 2x4s outside the tower which also supported the link. It was over 150' to the cement below. Right, I must have lost my presence of mind.
I don't mention that just for dramatic effect (after all, it's quite embarrassing that I could be that stupid), rather it's to show how easy it is for this 'blasé' effect to take hold when one's wrapped up in the minutiae of what one is doing.
One thing I've learned is that once one's equipment hits 400/500V and up things become very different and much more dangerous. For starters, component layouts often change due to large components and HV wiring often isn't located in just one part of the circuit but rather it can amble widely. Moreover, manufacturers aren't consistent in labeling the HV parts of the circuit. Where possible, one should always try to keep one of one's hands in one's pocket. ;-)
In some ways the problem is worse nowadays as everyone is now used to working on low voltage solid state devices, thus most will never encounter very high voltage electronics until they open their MW ovens and come across its magnetron's HV power supply. It's a worrying problem as many such ovens have inadequate or no HV warnings inside the case.
Incidentally, not long after posting my comment I noticed a few people down-voting it without comment. Sometimes I think I should not interfere and let evolution follow its normal course (as it nearly did with me).

Often you'll catch downvotes for playing devil's advocate, even when it's very justified like in this circumstance.
I'm one of those low voltage DC noobs and I was still shocked when I saw the title... I was even more shocked by the wood burning article - people are dying playing with this stuff. If anything that Linux-powered microwave article should have a huge warning at the top outlining the risks.
I appreciate you taking the time to educate on the dangers + sharing your anecdotes.
Yeah, right. I've looked again since these posts and if I hadn't seen the videos I'd have had difficulty in believing that so many people can be so damn stupid (there now seems so many more since when I last looked a while back).
Perhaps I'm just naïve and need more education in the matter of the human condition.
Hammocks are great if you're sleeping on a ship and don't have something gyroscopically stabilized. They change the big and unpredictable swings caused by waves into more predictable swings like a pendulum.
I would disagree that the kind of data being talked about lends itself to misuse. Management in general, and especially in well run companies, tends to be responsible and judicious in their use of various metrics and getting a good, holistic view of employee interactions and engagements is vital to ensuring that high performers are identified and adequately mentored.
Ideally, this type of data could be paired with a sentiment analysis engine and an emotional identifying model that could help coach negative employees toward more positive and beneficial interactions. This is an area that would require a delicate balance to prevent misuse, but, given most HR departments hesitance to act without strong background information, it would likely be a net positive in nearly every case.
'scuse me I need to go wash my mouth with soap. I just gamed the metrics that would be produced with this and I feel dirty.
Are you consuming entire animals? Just meat?
No snark there, either. Skeletal muscle alone isn't a complete diet. It's lacking in a few areas. Eating nothing but meat does seem to improve body composition, insulin sensitivity, some autoimmune conditions, some people report more steady energy levels... but, scurvy is eventually a problem, as will be hemochromatosis, among other things.
Can you tell me what areas this diet is lacking in? Scurvy is not a problem because fresh meat contains vitamin C. And hemochromatosis is not a problem either. It sounds to me like you're just hypothesizing here. In fact, people have known for centuries that fresh meat prevents scurvy.
yeah, it's 90% hypothesizing. Don't take it as me saying what you should or shouldn't do. Obviously, I'm not in a position to do that. It's just... if your neighbour pulled up with a car that's powered by cooking oil, you'd probably look at it and go "really? that can't work." and hope that he understands that it's curiousity, confusion and frankly a lack of knowledge of something so foreign.
I've seen a couple guys (father/son) try it out. Dad said it basically reversed his diabetes, son was pretty much OK the whole time I knew him.
I dunno man. Carnivore diets aren't for me. I just don't get how it works, doesn't mean that it doesn't work though.
thread poster could include a fourth alternative... the "hesitant adopter," left behind when they missed the bus early on and every goodname they wanted was taken while they took the tour of the service.
not even the badnamers want them. they're not the type to "go along to get along"
You could tell the cops weren't happy about it. These were women in their mid 50's and up who worked front desk jobs, not really a risk of violence.
All they wanted to do was go get their personal items and say goodbye to their peers. Some of them were forced to leave phones and purses behind and wait a week for them to be mailed to them.
It's one of those times in life where you see the mask slip off and realize who the people you've been dealing with actually are.

How is that even legal?
I wouldn’t leave without my personal belongings or I would file charges for theft with those cops.
