Which is the fastest algorithm to find prime numbers?
...ions for the SoE up to a range of about a billion. Much above that point, one generally needs to use page segmentation to overcome memory limitations, and that is where the SoA fails, taking rapidly increasing amounts of constant overhead with increasing range.

Is there an ignore command for git like there is for svn?
... the working copy. You should then add this .gitignore and commit it. Everyone who clones that repo will than have those files ignored.
Note that only file names starting with / will be relative to the directory .gitignore resides in. Everything else will match files in whatever subdirectory.

The difference between them is that in one case you count number of nodes and in other number of edges on the shortest path between root and concrete node.
Which is which?

Everyone says "oh I know about double evaluation, it's no problem" and a few months down the road, you'll be debugging the silliest problems for hours on end.
Note the use of __typeof__ instead of typeof:

Are C# events synchronous?
...l implemented synchronously.
The event handlers are executed sequentially, one after another, in the order they are subscribed to the event.
I too was curious about the internal mechanism of event and its related operations. So I wrote a simple program and used ildasm to poke around its implementa...
Why does PEP-8 specify a maximum line length of 79 characters? [closed]
...rules, and get on with writing good, consistently formatted code. Sure, no one really thinks that 79 is optimal, but there's no obvious gain in changing it to 99 or 119 or whatever your preferred line length is. I think the choices are these: follow the rule and find a worthwhile cause to battle for...
