Nitpicking the C variant: > #define BLQS_CMP(a, b) ((a) < (b)) A function that returns true when one operand is Less Than the other, should be called BLQS_LT. The CMP abbreviation is idiomatic for a function that returns -1,0, or 1.

In modern CPUs a mispredicted branch is much more expensive than a memory write. The unsaid assumption is that the array is filled with random values between 0 and 1000, so the "if" condition has a 50% of chances to be true. The b

UTF-8 notoriously doesn't prevent ambiguous encoding by construction, but only prohibiting it in the specs. It's known as overlong encoding. It's up to the encoder/decoder to prevent, correct, or reject it. This burden o

Some EVs use them to let the driver change the "drag" of the electric motors. Imagine the "L" (sometimes "B") position of automatic gear but with finer control than all-or-nothing.

When digital cameras replaced traditional ones, we thought it would make photography more democratic: each of us would be Helmut Newton for 15 minutes. But it didn't give us the beautiful portraits and inspired lanscapes we expected, o

I'd love to have 3 extra keys to assign to Ctrl-c, Ctrl-v and Alt-tab, but I keep bumping into these issues: RGB lights and other typical gaming design; proprietary app to install; huge real estate occupied on the desk.

You assume that human consumption means immediate human consumption. By this metric, there's no need for video encoders faster than the movie's own FPS, either.

The author forgot to add "fused" here, like they did in other parts of the same section. Non-fused: foreach i y[i] = cos(x[i]) foreach i z[i] = cos(y[i]) Fused, no intermediate variable: foreach i t = cos(

Interesting project! I'm eagerly reading through it. Probably I would have made different choices. For example, I'd rather have many modules that can be individually included, than one giant file. Also from a purely aesthetic poin

Yes, some restrictions seem arbitrary. Just like why these two types are not compatible: struct a {int data;}; struct b {int data;}; I know, I know, changing it would break existing code, etc.

A tombstone must be distinct from an empty element. In your example, you wouldn't stop at "d" because you haven't found an empty yet.

Technical analysis tells you that a stock is in its upwards trend. You invest all your money on it without thinking twice. The price goes down and you lose thousands of dollars. Is it a tool problem? LLMs spit out a sequence of tokens that

Mmm... so when looking for a non-existent key you have to go through the whole table. Hardly O(1)! A better strategy would be to first search the given range for the first empty slot, and exclude everything after that point. Then proceed lo
