Other than the space shuttle, by measuring deaths vs distance traveled per person, the elevator is the safest form of transportation. https://www.reddit.com/r/theydidthemath/comments/2qbjw2/requ... though I recommend reading more into it and doing your own math.
Isn't soyuz better than space shuttle on this metric?
As an automotive mechanic, this is awesome. You have no idea how many sensors/controllers in a car can only be reset by violating the DRM. Example: the suspension control computer for newer fords (so far just raptor and newer commercial F series) is separate from the ECU, and if it faults out you need to buy a new $2500 computer and sensor pack. You can, however, replace a commonly blown diode or fuse on the computer…

Now I operate a laser cutter, have a fairly extensive AutoHotKey script, can navigate my way around the post processor that generates the particular dialect of G-Code our laser prefers, and know a touch of python.
I'm definitely an outlier, but I'm not the only computer-nerd-come-metal-fabricator I've worked with.

I'm convinced most successful mechanics could be successful programmers. The skill set of looking at a problem and debugging until you really understand the architecture and design of what you're looking at is very similar in both fields.
Most programmers I know tend to be handy in some way, whether that's fixing their own cars (myself), wood working, or some other skill which requires them to think through problems and work with their hands.
I actually view fixing cars as not only a hobby of mine, but as a fall back career should I ever become bored of software or need some quick cash.

I live in central London in a 3-4 years old building (24 floors) and the elevators are truly a joke. Every 3-6 days they somehow get out of sync with which floor they are currently on, especially if you go first to -1, after that pretty much every floor will be wrong :) I always wonder who wrote it.
I know a guy who built an elevator system single board computer to control it. The big problem was the power to the board - the motor turning on and off and the old electrical system made it very spiky, which would cause the computer to glitch. He built in a lot of self-checking in the computer, but it would still fail once a day or so. He eventually fixed that by having the computer just hardware reset itself regula…

I'm a biolermaker ¹ with 20 years experience in the trade. Now I operate a laser cutter, have a fairly extensive AutoHotKey script, can navigate my way around the post processor that generates the particular dialect of G-Code our laser prefers, and know a touch of python.

I'm so grateful to EFF and the iRepair folks and everyone else who is out there "fighting the good fight" on behalf of us regular end-users! Great news!

It tells me that I really shouldn't buy a Ford car, since apparently billing for repair parts is more important to them than building a robust and repairable car. Adding a tamper resistant circuit to random bits of your car's electronics is adding cost while reducing robustness - who wants that in their car?
This is great! The push by large companies to replace personal asset ownership with perpetual rent is worth fighting against.
On that note, I wonder if the law will ever view misprepresenting the ownership of a device as fraudulent business practice. Suppose some hardware is sold to you, in the ancient ownership sense[1]. Then some time later, the maker decides that you must use only authorized parts, or they will not continue to provide a cloud service for it, or that it's just plain EOL. Then, you never really owned it - you were renting…
Am just interested if this may have the momentum to become a somewhat global "norm"
I have a feeling John Deere will be pissed to no end...and I will laugh endlessly.
Why do you believe they would be pissed?
