Why is GHC so large/big?
...getting 4 copies of GHC. Not only that, but the GHC binary itself is statically linked, so that's 5 copies of GHC.
We recently made it so that GHCi could use the static .a files. That will allow us to get rid of one of these flavours. Longer term, we should dynamically link GHC, but that's a big...
Why no generics in Go?
...ty interface to construct containers (with explicit unboxing) mean in many cases it is possible to write code that does what generics would enable, if less smoothly.
This remains an open issue.

How do you sort an array on multiple columns?

If owner names differ, sort by them. Otherwise, use publication name for tiebreaker.
function mysortfunction(a, b) {
var o1 = a[3].toLowerCase();

Differences between Agda and Idris
.... Idris puts high level programming ahead of interactive proof, although because Idris is built on a tactic-based elaborator, there is an interface to a tactic based interactive theorem prover (a bit like Coq, but not as advanced, at least not yet).
Another thing Idris aims to support well is Embed...

A fast method to round a double to a 32-bit int explained
...
A double is represented like this:
and it can be seen as two 32-bit integers; now, the int taken in all the versions of your code (supposing it's a 32-bit int) is the one on the right in the figure, so what you are doing in the end is just taking the lowest 32 bits o...
