PHP: exceptions vs errors?
...
Exceptions are thrown - they are intended to be caught. Errors are generally unrecoverable. Lets say for instance - you have a block of code that will insert a row into a database. It is possible that this call fails (duplicate ID) - you will want to have a "Error" which in this case is an "Exc...

Splitting templated C++ classes into .hpp/.cpp files--is it possible?
...the implementation of a template class in a separate cpp file and compile. All the ways to do so, if anyone claims, are workarounds to mimic the usage of separate cpp file but practically if you intend to write a template class library and distribute it with header and lib files to hide the implemen...
What does the brk() system call do?
...d load the "text" and "data" blocks into RAM starting at address zero (actually a little above address zero, so that the NULL pointer genuinely didn't point to anything) and set the break address to the end of the data segment. The first call to malloc would then use sbrk to move the break up and c...
Delete files older than 10 days using shell script in Unix [duplicate]
... these! Once, using a command very much like this in a cron job, I accidentally deleted every file on my production mail server older than 10 days, which I can tell you was no fun to recover from.

Any reason why scala does not explicitly support dependent types?
...h Pi[Foo.type]{type U = Int} = $anon$1@60681a11
scala> implicit val barString = new Pi[Bar.type] { type U = String }
barString: java.lang.Object with Pi[Bar.type]{type U = String} = $anon$1@187602ae
And now here is our Pi-type-using function in action,
scala> depList(Foo)
res2: List[fooInt...

Suppressing “is never used” and “is never assigned to” warnings in C#
...ll be returned. Just making it a public class that's empty with all public strings is nice short code and now no more warnings. Maybe using a dynamic class would be better as you don't have to explicitly state what's in the array, but I think this will be a nice reference for anyone hoping to use th...
