Why should hash functions use a prime number modulus?
...ween the items, like all having the same first character. This is a fairly predictable usage pattern, I'd say, so we don't want it to produce too many collisions.
It turns out that "because of the nature of maths", if the constant used in the hash, and the number of buckets, are coprime, then colli...
What is the point of a “Build Server”? [closed]
... build can see the appropriate code and processes the build artifacts in a predictable way. That way when a developer commits something with a problem, like not checking in a new file dependency, they can be notified quickly. Doing this in a staged area let's you flag the code that has built so th...
Android List View Drag and Drop sort
...nt implementation changes have been made.
DragSortListView has smooth and predictable scrolling while dragging and shuffling items. Item shuffles are much more consistent with the position of the dragging/floating item. Heterogeneous-height list items are supported. Drag-scrolling is customizable (...
Java URL encoding of query string parameters

As I predicted would happen ... users getting confused because obviously the problem is people need to encode more than just the parameter value. Its a very rare case that you only need to encode a parameter value. Its why I provi...

How unique is UUID?
... @TheTahaan That's not what random means. It doesn't mean "totally unpredictable" -- usually they follow some kind of distribution. If you flip 10 coins, the chance of getting 2 heads, followed by 3 tails, followed by 5 heads, is pretty low (2^-10, about 0.001). It's truly random, but we absol...
Random color generator
...eudo-code is here. It uses hsv rather than rgb, because hsv has much more predictable behavior. If you care to see the Python implementation, I used it here and here. You'll have to search through the code for "color".

Can multiple different HTML elements have the same ID if they're different elements?
...orks as expected in your current environments, and these IDs are used in a predictable/maintainable way, then there are only 2 practical reasons not to do this:

How to deal with a slow SecureRandom generator?
...generate secrets on new hardware out of the box, which might be in a quite predictable state. /dev/urandom/ won't block for entropy even though that's one case where you should. The situation is even worse if the secret is persistent, like if the first thing your device does on first boot is generat...
