Moment.js: Date between dates
...
You can use one of the moment plugin -> moment-range to deal with date range:
var startDate = new Date(2013, 1, 12)
, endDate = new Date(2013, 1, 15)
, date = new Date(2013, 2, 15)
, range = moment().range(startDate, endDate);
range.contains(date); // false

How do I generate random number for each row in a TSQL Select?
...with a uniform distribution:
ABS(CHECKSUM(NewId())) % 14
To change your range, just change the number at the end of the expression. Be extra careful if you need a range that includes both positive and negative numbers. If you do it wrong, it's possible to double-count the number 0.
A small warni...
Generating random integer from a range
I need a function which would generate a random integer in given range (including border values). I don't unreasonable quality/randomness requirements, I have four requirements:
...
What is an unsigned char?
...s as numbers, use:
signed char, which gives you at least the -127 to 127 range. (-128 to 127 is common)
unsigned char, which gives you at least the 0 to 255 range.
"At least", because the C++ standard only gives the minimum range of values that each numeric type is required to cover. sizeof (cha...
Revert a range of commits in git
How can I revert a range of commits in git? From looking at the gitrevisions documentation, I cannot see how to specify the range I need. For example:
...
Why do Python's math.ceil() and math.floor() operations return floats instead of integers?
...
The range of floating point numbers usually exceeds the range of integers. By returning a floating point value, the functions can return a sensible value for input values that lie outside the representable range of integers.
