In US/Canada, power supply is done via 240V split phase. Therefore, a broken neutral between service and home would have lead to a 120V outlet getting anywhere between 0 and 240V AC. That sure would have lead to something a lot less pleasant than just gzip errors.

In US/Canada, it is safe and code compliant to have floating ground in a GFCI protected outlet. The GFCI provides the safety benefit that ground is supposed to provide. Obviously having both GFCI and ground is better, but having only the former is allowed. Occasionally, ground serves additional purposes beyond safety, but that doesn’t apply for a computer power supply.

Additionally, in US/Canada, it is unsafe (and against code) to wire a new outlet directly to water pipe. Ground-neutral bond is required at the main service panel because the “ground” (soil, water pipe, etc) isn’t a good enough electricity ground. The ground wire in the outlet must be wired to the main panel (directly, or through subpanels), where 3 things are connected together: neutral bus, ground bus, and the “ground” (soil, water pipe, etc).

All in all, the author didn’t find the root cause of the problem. And in trying to fix the problem, the author introduced more bugs.

I don’t see any irony about the bank’s behavior here. In this specific case, the bank appears to be acting consistently.

Universal “free lunch” is cheaper to manage, avoids filtering out children who needs it (but is filtered out due to administrative error or rigid rules), prevents children’s embarrassment, etc.

I don’t really know how Twitter could have done better.

Assuming you’re right, it’s really sad that multiple sibling posts assume that the app was doing something shady and selling the user’s data. It shows, in general, how little trust people have in apps on their own phones.

Historically, ray tracing is only used for movies whereas games generally uses rasterization. The former is highly coherent workload, and is great for GPU. The latter is incoherent workload, and generally isn't suitable for GPU.

Games have started using ray tracing, and there have been GPU implementation of ray tracing in the past 5 or so years. What I said above may be stale.

Read "22. Does RCV satisfy the monotonicity criterion?"

Say, there's 3 candidates. You want A to win. You think A will lose to B in a 1-on-1 match, but would win C. So you vote C-A-B (or C-B-A, doesn't matter) to increase the likeliness that B got eliminated in the 1st round. Of course, you're now saying that you prefer C over A in a 1-on-1 race. But that's fine because other people will vote for A.

Concretely, let's say this is people's actual choice.

31 B-A-C; 39 A-B-C; 30 C-B-A

B wins.

Now, if 2 people preferring A (voted A-B-C) strategically change their vote to C-B-A.

31 B-A-C; 37 A-B-C; 32 C-B-A

Now, A wins.

I can see why you may feel offended, but I don't think the parent post deserves your anger.

Many phones manufactured after 2005 have GPS receivers built in. When the cellular phone detects that the user is placing an emergency call, it begins to transmit its location to a secure server, from which the PSAP can retrieve it. Cellphone manufacturers may program the phone to automatically enable GPS functionality (if disabled) when an emergency call is placed, so that it may transmit its location.
