The short lifetime of most objects should be implicit from scope and obvious to the programmer. It's usually easier that way, and certain GC-based languages ended up adding special syntax to add that level of control for objects when t

Lots of ISAs consider 32-bit to be a 'word'. And now they have the same problem that Intel already encountered that it's easier to start referring to a new larger native word size as a 'double-word' and the cycle co

Yes, I have found that being "against murder" is political and a matter of political alignment. Especially since the definition of what is murder, or who is protected by murder laws, and the punishments for murder are all controve

When it's a commonly committed crime but only certain people get prosecuted, it reaks of high-level corruption. Sounds like this exec stepped on the wrong toes.

What you're saying is not backed up by the numbers. One of the reasons the army stepped in is because our demand exceeded what we could supply with our number of tankers. So we had enough tanker drivers, but not enough tankers. The tan

You get better algorithmic performance, but whether a tree or a linked list you get bad locality versus open bucket.

I said 'sorted' but I meant balanced as well. And even if you can 'attack' still, there is a limit to how slow it can get. Worst case O(log n) is not bad. As for security, I can't speak to its efficacy, but I know i

It makes a significant difference in profiling, versus i.e. a bitwise mask to find a modulus for a power-of-two size.

The O(n) behavior is not even really that 'pathological', lots of normal cases get that behavior. If SwissTable operates as you say, then it sounds like it is prone to bad performance for lots of normal data with a dumb hash, i.e.

by veltas 5y ago
The clustering can still happen with any walk. The dumb walk is the best, but it is the most prone to clustering if the hash is simplistic. But if the hash is pseudo-random, it's as likely to get clusters as any other walk, and has bet

by veltas 5y ago
Another alternative is not using a hash table, and instead using a sorted binary tree or similar, which tends to be slower on average but has worst case O(log n) lookup, O(log n) insertion. Depends on your criteria.

Open addressing or 'open bucket' hash tables always seem to be a second consideration in textbooks or blogs. I find them generally faster, and more memory efficient, and easier to implement. Instead we're always taught the cl

The building analogy doesn't work, software is not a building. There are essentially templates for buildings, there is no template for software. Maybe software is more like a city. Maybe buildings are more like patterns, data structure

I think this was only considered acceptable because in early C you couldn't initialise automatic variables. So you would never be confused by an association like `char *p = q; *p = q;`, because you couldn't write that first part.
