Is there a use-case for singletons with database access in PHP?
...panying need to do a LOT of stuff with a lot of different stuff in a cheap/fast/reliable fashion, singletons may not seem so necessary. And it may even be nuisance/impediment to what they ALREADY have.
But for those who needs to work in the dirty trenches of 'agile' development, having to implemen...
What are the differences between Generics in C# and Java… and Templates in C++? [closed]
...omething like ListOfPerson.
The benefit of this is that it makes it really fast. There's no casting or any other stuff, and because the dll contains the information that this is a List of Person, other code that looks at it later on using reflection can tell that it contains Person objects (so you g...

... method and especially if you have a lot of text, but if you want to do it fast without using a database, this method could work, though, you can't allow users to input data which will be used as translation-files. But if you add the translations yourself, it will work:
Let's say you have this text...
What would cause an algorithm to have O(log n) complexity?
...mic.
So where does this come up? One classic example is binary search, a fast algorithm for searching a sorted array for a value. The algorithm works like this:
If the array is empty, return that the element isn't present in the array.
Otherwise:
Look at the middle element of the array.
If it...
Cartesian product of x and y array points into single array of 2D points
... output for arrays of the same size. The meshgrid + dstack approach, while faster in some cases, can lead to bugs if you expect the cartesian product to be constructed in the same order for arrays of the same size.

Why would I want stage before committing in Git?
... the mode, file name, a staging number, and some cache data to make Git go fast. But unless you get into working with some of Git's low-level commands—git ls-files --stage and git update-index in particular—you can just think of it as a copy.
3The git ls-files --stage command will show you the ...

... high frequency
This comes from the idea that a performance problem may be fast-acting, and that samples have to be frequent in order to hit it. But, if the problem is costing, 20%, say, out of a total running time of 10 sec (or whatever), then each sample in that total time will have a 20% chance o...
What is the difference between bottom-up and top-down?
...at you are doing.
In many applications the bottom-up approach is slightly faster because of the overhead of recursive calls. Stack overflow can also be an issue in certain problems, and note that this can very much depend on the input data. In some cases you may not be able to write a test causing ...
