'printf' vs. 'cout' in C++
...ould look like %2$s oru %1$d.\n. Now, how to do it in C++? Well, I have no idea. I guess you can make fake iostream which constructs printf that you can pass to gettext, or something, for purposes of translation. Of course, $ is not C standard, but it's so common that it's safe to use in my opinion....

How to limit setAccessible to only “legitimate” uses?
...

When to use Storyboard and when to use XIBs
...iggest criticism about Storyboards is their implementation rather than the idea behind them. Most of the points that I outline could be fixed with better tools and a better implementation (one that lets a human track and understand changes, for example).

Are static class variables possible in Python?
... t do not affect new instances of Test
# Namespaces are one honking great idea -- let's do more of those!

{'i': 6, ...}

Notice how the instance variable t.i got out of sync with the "static" class variable when...
Why does base64 encoding require padding if the input length is not divisible by 3?
...e stream correctly and there would be no need for padding.
That's a great idea, as long as we know the length of the data we're encoding before we start encoding it. But what if, instead of words, we were encoding chunks of video from a live camera? We might not know the length of each chunk in adv...
How do you clear the SQL Server transaction log?
...DBCC SHRINKDATABASE and the maintenance plan option to do the same are bad ideas, especially if you really only need to resolve a log problem issue. Target the file you want to adjust and adjust it independently, using DBCC SHRINKFILE or ALTER DATABASE ... MODIFY FILE (examples above).

Relative imports in Python 2.7
... ret = doctest.testmod()
sys.exit(0 if ret.failed == 0 else 1)
The idea here is this (and note that these all function the same across python2.7 and python 3.x):
If run as import lib or from lib import foo as a regular package import from ordinary code, __package is lib and __name__ is lib....
