Intersection and union of ArrayLists in Java
...mentation without using any third-party library. Main advantage over retainAll, removeAll and addAll is that these methods don't modify the original lists input to the methods.

Convert string to List in one line?
...
@Dan: I agree, and generally I do use the params overload. But for an answer to a question sometimes I feel like verbosity is better. Just a matter of opinion really.

Why is there no Tree class in .NET?
...BCL. I suspect this is because the choice of whether to use a tree is typically an implementation detail and is otherwise an unconventional way to access data. That is, you don't say, "binary-search-for element #37"; instead, you say, "get me element #37".
But have you taken a look at C5? It's supe...
What is the _snowman param in Ruby on Rails 3 forms for?
...net Explorer (5, 6, 7 and 8) to encode its parameters as unicode.
Specifically, this bug can be triggered if the user switches the browser's encoding to Latin-1. To understand why a user would decide to do something seemingly so crazy, check out this google search. Once the user has put the web-sit...

How do I use LINQ Contains(string[]) instead of Contains(string)
...ght, but you need to create a List<string> from string[] first. Actually a List<int> would be better if uid is also int. List<T> supports Contains(). Doing uid.ToString().Contains(string[]) would imply that the uid as a string contains all of the values of the array as a substr...
Transaction isolation levels relation with locks on table
...B just executes a SELECT statement to read data. C reads and updates data. All these process work on the same table T.
READ UNCOMMITTED - no lock on the table. You can read data in the table while writing on it. This means A writes data (uncommitted) and B can read this uncommitted data and use it...
Why does GCC generate such radically different assembly for nearly the same C code?
...e(). I'll spare you the assembly, but it is identical - register names and all.
Step 2: Mathematical reduction: x + (y ^ x) = y
sign can only take one of two values, 0 or 0x80000000.
When x = 0, then x + (y ^ x) = y then trivial holds.
Adding and xoring by 0x80000000 is the same. It flips the sign...
