For some of the customers that we develop software for, we are required to "guarantee" a certain amount of spare resources (memory, disk space, CPU). Memory and disk space are simple, but CPU is a bit more difficult.
One technique that we have used is to create a process that consumes a guaranteed amount of CPU time (... | [

I just figured out that I can actually **store objects in the $\_SESSION** and I find it quite cool because when I jump to another page I still have my object.

In order to improve performance reading from a file, I'm trying to read the entire content of a big (several MB) file into memory and then use a istringstream to access the information.
My question is, which is the best way to read this information and "import it" into the string stream? A problem with this approach (... | [

Assigns `null` to `s` if `o` is not a `string` or if `o` is `null`. For this reason, you cannot use it with value types (the operator could never return `null` in that case). Otherwise, assigns `o` to `s`.

only seen a need for this return-null type of functionality with badly designed libraries which use error codes (e.g. return null = error, instead of using exceptions).
3 is not a cast and is just a method invocation. Use it for when you need the string representation of a non-string object. | [

goto startsort;
