How do I get Windows to go as fast as Linux for compiling C++?
...lookup times, with a btree structure. In Linux (last I looked), an app can read an entire folder with a single system call, and iterate through the resulting structure entirely in user code; Windows requires a separate sys call for each file. Either way, compilers shouldn't need to read the entire f...
How do I convert an enum to a list in C#? [duplicate]
...uperfluous, and will mean extra copying. Enum.GetValues returns an array already, so you just have to do var values = (SomeEnum[])Enum.GetValues(typeof(SomeEnum))

Will strlen be calculated multiple times if used in a loop condition?
...is only true if ss is not changed in for loop.
For example, if you use a read-only function on ss in for loop but don't declare the ss-parameter as const, the compiler cannot even know that ss is not changed in the loop and has to calculate strlen(ss) in every iteration.

How to store date/time and timestamps in UTC time zone with JPA and Hibernate
...that they transform dates to/from the current JVM timezone by default when reading and writing from/to the database.
I came up with a solution to this in Hibernate 3.5 by subclassing org.hibernate.type.TimestampType that forces these JDBC methods to use UTC instead of the local time zone:

What's the _ underscore representative of in Swift References?
...e designers think it's obviously enough for your code and doesn't enchance readability, quite the contrary, it soils the code. So you get the warning. The reference has the opposite goal: it has to be as clear as it's possible - so the first parameter's underscore is mentioned for EVERY method. That...
