Naming of ID columns in database tables
... you have many tables with ID as the id you are making reporting that much more difficult. It obscures meaning and makes complex queries harder to read as well as requiring you to use aliases to differentiate on the report itself.
Further if someone is foolish enough to use a natural join in a dat...
Why would one use REST instead of SOAP based services? [closed]
...PUT, GET, etc. that have to otherwise be represented in a SOAP envelope).
More standardized - HTTP operations are well understood and operate consistently. Some SOAP implementations can get finicky.
More human readable and testable (harder to test SOAP with just a browser).

Generate random numbers following a normal distribution in C/C++
..., then the polar method is faster, though. And the Ziggurat algorithm even more (albeit much more complex to write).

Is Unit Testing worth the effort? [closed]
...oes not mean writing twice as much code, or coding slower. It's faster and more robust than coding without tests once you've got the hang of it. Test code itself is usually relatively trivial and doesn't add a big overhead to what you're doing. This is one you'll only believe when you're doing it :)...
Regex - Should hyphens be escaped? [duplicate]
... escape it (e.g. [a-z\-0-9]) in order to add "hyphen" to your class.

Why can't I define a default constructor for a struct in .NET?
... that constructor to be executed in all cases - but that would have led to more confusion. (Or at least, so I believe the argument goes.)
EDIT: To use your example, what would you want to happen when someone did:
Rational[] fractions = new Rational[1000];
Should it run through your constructor 1...
