Default function arguments in Rust
...
If you are using Rust 1.12 or later, you can at least make function arguments easier to use with Option and into():
fn add<T: Into<Option<u32>>>(a: u32, b: T) -> u32 {

iPhone App Icons - Exact Radius?
...factory designer) and all the answers so far on this post are wrong (or at least incomplete). Apple starts with the 57px icon and a radius of 10 then scales up or down from there. Thus you can calculate the radius for any icon size using 10/57 x new size (for example 10/57 x 114 gives 20, which is t...

Storing money in a decimal column - what precision and scale?
...The rule of thumb for storage of fixed point decimal values is to store at least one more decimal place than you actually require to allow for rounding. One of the reasons for mapping the old Currency type in the front end to DECIMAL(19, 4) type in the back end was that Currency exhibited bankers' r...
Where is a complete example of logging.config.dictConfig?
