I have replaced pieces of C++ standard library quite a few times. std::list calls malloc/free for every node instead of a bunch of them, expensive. Also they are doubly linked, for some applications a single-linked lists fit better. st

File systems need backward compatibility. 40 years ago, it wasn’t clear people gonna invent Internet and start moving files across time zones. Keeping file modification time according to local clock was reasonable idea at that time. The FAT

It’s pretty fast. Likely reason for that, MS designed both language and runtime this way since version 1.0. They needed that for their Windows Forms which consumes huge chunk of WinAPI. I benchmarked a while ago when testing this library h

Hardware requirements are up to the product management. For instance, many modern videogames (they generally want compatibility because directly translates to sales) no longer support 32-bit or pre-AVX1 processors. Technically, Julia can dr

They are comparable. The most efficient shipping method is by sea, the fastest one is by air. The importance of that chokepoint is debatable. Flying distance to Moscow is different but not substantially so, 450 versus 600 km. There's n

This became true as the war continues. Wasn't the case in February. Western intelligence was expecting Russians to capture Kyiv within several days of the war [1] Therefore, western countries refused to supply heavy weapons. They remem

Right, unpacking numbers like that is pretty efficient in AVX512. Still, modern processors have BMI2. For some practical applications, the PEXT instruction is pretty comparable, here’s an example: https://stackoverflow.com/a

The HKEY_CURRENT_USER key is just an alias within the same DB, it points to some key under HKEY_USERS. I don't think this counts as another instance of the DB, despite stored in separate files. ESENT databases are independent: a databa

Each Windows installation only has 1 registry, but it normally has multiple ESENT databases https://en.wikipedia.org/wiki/Extensible_Storage_Engine These databases are NoSQL as well. Albeit somewhat closer to tradition

It’s totally fine when the service in question is not a natural monopoly. Youtube is a natural monopoly now, just like residential water and electricity suppliers. Too bad it’s not yet regulated as such.

I would do the SSE version slightly differently. No need for bitwise tricks, SSE2 has an instruction to compare bytes, which saves 1 instruction and one constant vector. int luhn( const char* s ) { __m128i r = _mm_loadu_si
