What's the difference between lists and tuples?
...er.
Using this distinction makes code more explicit and understandable.
One example would be pairs of page and line number to reference locations in a book, e.g.:
my_location = (42, 11) # page number, line number
You can then use this as a key in a dictionary to store notes on locations. A li...
What is code coverage and how do YOU measure it?
...bout it and can't give you a link.
As to how we use it - code coverage is one of our exit criteria for each milestone. We have actually three code coverage metrics - coverage from unit tests (from the development team), scenario tests (from the test team) and combined coverage.
BTW, while code cov...

AES Encryption for an NSString on the iPhone
... encryption.) I want to write a method which takes two NSString instances, one being the message to encrypt and the other being a 'passcode' to encrypt it with - I suspect I'd have to generate the encryption key with the passcode, in a way that can be reversed if the passcode is supplied with the en...
How to remove leading zeros using C#
...depends on how long the NVARCHAR is, as a few of the above (especially the ones that convert through IntXX) methods will not work for:
String s = "00578032758432906750678065706578637806175465453216495326495246921546293456291456219456214951624951629456321943785904375843058706674893264732981468719467...
What is a “surrogate pair” in Java?
...y is used to store values above this range (0x10000 to 0x10FFFF). This is done using pairs of code units known as surrogates.
The surrogate code units are in two ranges known as "high surrogates" and "low surrogates", depending on whether they are allowed at the start or end of the two-code-unit se...
Group vs role (Any real difference?)
Can anyone tell me, what's the real difference between group and role? I've been trying to figure this out for some time now and the more information I read, the more I get the sense that this is brought up just to confuse people and there is no real difference. Both can do the other's job. I've alw...
Assembly code vs Machine code vs Object code?

It may also contain placeholders or offsets not found in the machine code of a completed program. The linker will use these placeholders and offsets to...
What is the difference between gravity and layout_gravity in Android?

@Thupten Very good question. I guess one will prevail (I guess the children's layout_gravity) and the other one is only the default for the prevailing one.
