bool to int conversion
...se of such types (often declared using the identifier bit). On e.g. a mid-range PIC, if (bitVar1) bitVar2=1; would be two instructions; optimal coding for if (byteVar1) byteVar2=1; would be at least four (on many compilers, probably five). Such types can thus offer a major performance boost.

How can I make an “are you sure” prompt in a Windows batchfile?
...n operators EQU and NEQ are designed primary for comparing two integers in range -2147483648 to 2147483647 and not for comparing two strings. EQU and NEQ work also for strings comparisons, but result on comparing strings in double quotes on a useless attempt to convert left string to an integer. EQU...

If you look at the validationParameter attribute we see a range of 0 to 2592000 seconds (the ,60 specifies the granularity of the setting, in this case the value must b...
Why is Thread.Sleep so harmful
...fferent versions/types of
Windows and different processors and generally ranges from 15 to 30
milliseconds. This means the thread is almost guaranteed to block for
more than n milliseconds. The likelihood that your thread will
re-awaken exactly after n milliseconds is about as impossible a...

... to make sure that is a valid syntax and does what you intend with a fully range of test URIs.
See regexpCheck.php below for a simple script that you can add to a private/test directory in your site to help you do this. I've kept this brief rather than pretty. Just past this into a file regexpChec...

The following code will draw both series that they use up the whole y axis:

Where in memory are my variables stored in C?
...contains the executable code. The instruction pointer takes values in this range.
Data segment: contains global variables (i.e. objects with static linkage). Subdivided in read-only data (such as string constants) and uninitialized data ("BSS").

How to remove from a map while iterating it?
...n ordinary for loop here, since we are modifying the container itself. The range-based loop should be strictly reserved for situations where we only care about the elements. The syntax for the RBFL makes this clear by not even exposing the container inside the loop body.
