Let's see.
Starting with our nums list to make sure, the content is still the same.
nums
[-3, 1, 4, 5, 7, 8, 9, 14]
nums.sort()

What is the most accurate way to retrieve a user's correct IP address in PHP?
...ou would know is that it was forwarded for a shared network.
Then I won't start much into it, but dynamic IP addresses are the way of broadband anymore. So. Even if you get a user IP address, expect it to change in 2 - 3 months, at the longest.

Inherit from a generic base class, apply a constraint, and implement an interface in C#
...to criticize you either. I was not used to reading spec earlier but I have started reading it thanks to Jon, Eric and Pavel who always quotes C# spec for any question. I found that C# spec, even though it could be hard to read at times, is a great way to learn about the language.

Unignore subdirectories of ignored directories in Git
...as the most-upvoted answer is incorrect, and easily demonstrable as such.
Start with ignoring everything in uploads/*:
mkdir -p uploads/rubbish/stuff/KEEP_ME
touch uploads/a uploads/rubbish/a uploads/rubbish/stuff/a uploads/rubbish/stuff/KEEP_ME/a
echo '/uploads/*' >> .gitignore

Setting variable to NULL after free
... code between the declaration and the first initialization, somebody might start using the variable even though it has no value yet. If you null-initialize, you get the segfault; without, you might again read or write random memory. Likewise, if the variable later gets initialized only conditionally...
