Making sure the Direction flag is clear on entry and return is a somewhat hidden requirement of stdcall (Windows calling convention), but it didn't crash if you set it in WindowProc and forgot to clear it until Windows XP. More recentl

No, no, the cool thing to do now is to defend it. You claim that critics just don't understand its purpose, even if they mention it multiple times and are only criticising misuse. Then you use it ironically in your professional present

Just use n = max(a, b). Of course that doesn't help you much unless you're adhering to strict safety standards (e.g. power of ten rules), it just shifts the burden of proof from termination to correctness. And there's no such

Yes, that is the point I tried to make. Use simple, constrained forms such as (C) "for(int i = 0; i < n; i++) { ... }" with n an int and no modification of i in the body, or (Python) "for e in l:" where l is a list th

Iterative loops are much easier to analyze and reason about, by humans and by computers. For example, they always terminate. To paraphrase Dijkstra, "I regard general recursion as an order of magnitude more complicated than just repeti

I agree that the staircasing effect is definitely the biggest drawback of Total Variation. In the "Smoothed" picture the noise is removed but the results are blocky. The first way to deal with it is to take into account higher pow

Let me share my experience with chroma upsampling and smooth jpeg decoding. At first, I optimized each channel, then upsampled the chroma channels using replication. This works terribly as you can see in the article. So then I changed to li

If you start with the most general form you won't always get an optimal solution, because two jumps may be blocking each other from optimizing. TASM does it that way. Consider (16-bit NASM): a: times 124 nop jmp b jmp a tim

It's probably insecure, because you don't want to do 75,850,000 sequential evaluations over a network. It would take over a week for a single track with even just 10ms response time.

The domain is the unit cube [0, 1]^d using double precision floating point, see the documentation. Making assumptions and testing them is very much part of the contest. You are even allowed to do this interactively.
