While I have not really played SE (past initial launch, it was too daunting to build the ship in space, etc) I have run into these kind of "issues" in Factorio. While they can have disastrous effects, I often really enjoy finding the core problem and finding a solution to make it "fail-safe". Sometimes I wish I could go back and wipe all my Factorio knowledge and start from scratch again, most importantly refusing to…

I found I enjoyed the process of putting together a mall from a blueprint, but leaving the rest of the factory up to me. I find the logistics and planning part of factorio more interesting than the "build up all the parts you need to make the factory" part.

they didn't always fail safe. I remember a house at the bottom of a steep mountain grade that got plowed into on a regular basis especially during that time. EDIT: hmm... seems freezing might still be a way to cause failure?

Failure at the bottom of a steep hill is a different type of failure caused by brake fade due to the brake drum swelling with heat as the truck goes down the hill.

But I believe at some point air brakes had to be reversed by law.

In other words, the brakes would apply on loss of pressure, instead of via pressure.

To clarify, by a “standard” keyboard I mean a (usually US) QWERTY PC keyboard with 101 to 105 keys (depending on the amount of Win/Super and Menu keys and the presence of an additional punctuation key to the left of Z). Those have three rows of three keys each above the arrows (not counting any “media keys” such as Power); the topmost one of those is PrintScreen / SysRq, Scroll Lock, and Pause / Break, though some of…

I know what you meant. I was implying that a 101-105 key keyboard has not been standard for a decade or more. I would be willing to bet that none of the ten most popular/best-selling computers in the country for the last 5-10 years have had a key that says “break”.

Even on laptops, there's still usually a Pause/Break key, it's just merged with something else such that you have to use Fn.

For example, on most modern Thinkpads, Pause is Fn+P, and thus Break is Ctrl+Fn+P.

Also issue with golang (+ protobufs) where you can't distinguish a populated zero value from the default "not present" value.

C# linqs method - first or default has the same problem

The method itself just uses the default value of the corresponding type. If you have a sequence of ints, and you cast it to Nullable first before applying FirstOrDefault, then you can distinguish between null and 0.

Hmm, what does he mean "I woke up the next day"? Did he leave Factorio running, or did it get an online component while I wasn't looking?

the problem is that while it also breaks search for the inflammatory assholes that want to ruin everyone's day, it also breaks search for everyone else . it's a strange problem, to be sure. "I want to speak publicly about something in the market-place square, but in such a way as to avoid the nay-sayers and rabble-rousers.' -- this seems like a problem that was fixed in ye days' of olde by forming secret collectives…
