C# switch statement limitations - why?
...onstant time branch. The compiler may find short-cuts (using hash buckets, etc), but more complicated cases will generate more complicated MSIL code with some cases branching out earlier than others.
To handle the String case, the compiler will end up (at some point) using a.Equals(b) (and possibl...

Why should I not include cpp files and instead use a header?
..., x = y + 1, that means you have to compile all two million lines again in order to test this. And if you find out that you meant to do a x = y - 1 instead, then again, two million lines of compile are waiting for you. That's many hours of time wasted that could be better spent doing anything else...
C# int to byte[]
... trying to say that a signed integer is a normal 4-byte integer with bytes ordered in a big-endian way.
Now, you are most probably working on a little-endian machine and BitConverter.GetBytes() will give you the byte[] reversed. So you could try:
int intValue;
byte[] intBytes = BitConverter.GetByt...
Getting “type or namespace name could not be found” but everything seems ok?
...
The compiler compiles according to the project build order, so if there is a genuine error in one project it can get lost in a sea of red-herring "type or namespace could not be found" errors - because it just exits when it finds the error, and doesn't get to updating the refer...

Should programmers use SSIS, and if so, why? [closed]

Passing arrays as parameters in bash
...d when given as parameters.
Note that this still works even with descTable etc being defined with local, because locals are visible to the functions they call.
The ! in ${!1} expands the arg 1 variable.
declare -a just makes the indexed array explicit, it is not strictly necessary.

Why is creating a new process more expensive on Windows than Linux?
...eateProcess' in Windows and having it load the exe image, associated dlls, etc.
In the fork case the OS can use 'copy-on-write' semantics for the memory pages associated with both new processes to ensure that each one gets their own copy of the pages they subsequently modify.
