Fusible traces aren’t uncommon - but they would effectively destroy the device if current limits are exceeded, and they certainly would be if the power supply is non-isolated, so it wouldn’t actually be a solution to the firmware update problem.
The usual solution here is an optical coupling of some kind - optocouplers (a box with a LED, photodiode, and air gap between them) are very common for this purpose, and are an inexpensive and effective option for digital signaling across an isolation boundary.
In this case they’ve basically built a custom optocoupler out of discrete components, which is a bit unusual, but makes sense when you consider the risk of corrosion due to water ingress at the diagnostic ports, and the need to access it while - for example - a dishwasher cycle is running.
It was originally a switching/signalling waypoint, and later started seasonal passenger service for skiiers in 1932, before later switching to year-round service. Apparently it used to be a popular hiking destination as well, but with the establishment of more convenient rail and road routes became less popular in the 80s.
In this case, the problem was the seed was low entropy, so if you generated a bunch of random numbers with a single initialization of the RNG seed you would get unique values. It's a tricky scenario to test for if you don't know of the failure mode...
Any kind of turn costs lift, and that’s not what you want to spend when you’re trying not to hit something on the ground. As such turns are generally not performed below a certain altitude.
Japan has a good solution for this - most of the larger train stations (and many of the medium-sized ones as well) have "coin lockers" (which, despite the name, these days often take transit IC cards instead of coins) you can rent to store your stuff until you're ready to head home. In larger tourist hubs like Akihabara there'll also be a ton of lockers in the vicinity of the station run by third parties as well.
TASBot was only controlling controller 1 for a short time, but it remained connected to controllers 2-4 for the entire run, giving it time to download additional content as the showcase was going on.
Do you want to elaborate on which specific changes listed in the article are, in your opinion, beneficial to institutional investors at the expense of retail investors, and how?
The state _could_ attempt to negotiate with bondholders to repurchase the bonds - probably at a significant premium, however. Of course, if one of the bondholders refuses to sell, there wouldn't be much they can do... (I wonder if Disney holds any of those bonds for this very reason?)
Much harder for a large company than a small one, actually. The coordination overhead to get a bunch of disparate teams in a large company to rearchitect the fundamental structure of the service should not be overlooked.
