Dynamic Sorting within SQL Stored Procedures
...eah, it's a pain, and the way you're doing it looks similar to what I do:
order by
case when @SortExpr = 'CustomerName' and @SortDir = 'ASC'
then CustomerName end asc,
case when @SortExpr = 'CustomerName' and @SortDir = 'DESC'

How do I automatically scroll to the bottom of a multiline text box?
...kering scrollbar if you're calling it in a loop.
It also happens to be an order of magnitude faster than concatenating onto the .Text property. Though that might depend on how often you're calling it; I was testing with a tight loop.
This will not scroll if it is called before the textbox is sho...
How can I check file size in Python?
...any other unit. If you do a right shift by 10 you basically shift it by an order (multiple).
Example: 5GB are 5368709120 bytes
print (5368709120 >> 10) # 5242880 kilobytes (kB)
print (5368709120 >> 20 ) # 5120 megabytes (MB)
print (5368709120 >> 30 ) # 5 gigabytes (GB)

You have to realize that you are only saving two characters and with some people's bracing styles you aren't even saving a line. I prefer a full brace style (like follows) so...
Why does the order of the loops affect performance when iterating over a 2D array?
... x[1][0] etc...
Meaning that you're hitting them all in order. Now look at the 1st version. You're doing:
x[0][0]
x[1][0]
x[2][0]

Sorting arrays in NumPy by column
... actually the most elegant way of doing it.
For the "correct" way see the order keyword argument of numpy.ndarray.sort
However, you'll need to view your array as an array with fields (a structured array).
The "correct" way is quite ugly if you didn't initially define your array with fields...
