What is the difference between int, Int16, Int32 and Int64?
...n int16 takes as much space as an int32 (and actually an int64) because in order for most operations to be efficient, we pad around the data to make accesses aligned to 32 or 64 bit boundaries (in 32 or 64 bit modes respectively). This is because unaligned accesses are ridiculously inefficient on so...
Declaring pointers; asterisk on the left or right of the space between the type and name? [duplicate
...Pointer; (b) typedef Cat* CatPointer; When writing a typedef the other order via "using" though, it becomes clearer which word the asterisk belongs with in a typedef, since the first one works, and the second is uncompilable nonsense. (a) using CatPointer = Cat*; (b) using *CatPointer = ...

Can you split a stream into two streams?
...ead-safe. Additionally, assuming the use of non-parallel streams, only the order is not guaranteed, so they are thread-safe. It's up to the programmer to fix concurrency issues, so this answer is perfectly suitable if the collections are thread safe.

When should I use Write-Error vs. Throw? Terminating vs. non-terminating errors
...
In advanced functions, you must use $PSCmdlet.ThrowTerminatingError() in order to generate a statement-terminating error.
Note that, by contrast, the Throw keyword generates a script-terminating error that aborts the entire script (technically: the current thread).
Handling a statement-terminatin...
Eclipse - no Java (JRE) / (JDK) … no virtual machine
...ession, you can want to register an older SDK (including a non-Sun one) in order to run/debug your programs with a JRE similar to the one which will actually be used in production.

Multiline string literal in C#
...literal I find is that it can make your code look a bit "weird" because in order to not get spaces in the string itself, it has to be completely left aligned:

Yuck.
So the solution I like to use, which keeps everything nicely aligned with the res...

List comprehension vs. lambda + filter
...terator object, so you'd have to pass your filter method call to list() in order to build the filtered list. So in python 2:
lst_a = range(25) #arbitrary list

lst_c = filter(lambda num: num % 2 == 0, lst_a)
lists b and c have the same values, and wer...
