R vs. RRO (OpenBALS vs. MKL)

The Revolution R Open (RRO) just released a new version based on R 3.12 (Intel MKL). I installed this on Mint 17.1. Now I want to compare its performance against the vanilla R 3.12 I installed on Manjaro a few days earlier, which as compiled against OpenBLAS. I used the benchmark test provided here.

RRO + MKL: 7.347 sec
R + OpenBLAS: 7.557 sec

Now it's a tie.

Why R is Hard to Learn

A long list of reasons here. Power and flexibility do come with a price, I guess. From a user perspective, a big part of learning R is about identifying a set of key packages that suite your needs best.

Manjaro 0.8.11

The newly released Manjaro Linux is surprisingly stable and polished. After playing with it for a day (virtual machine installation), I think I am going to keep it. As it matures, it can be a viable competitor for a serious workstation OS.

Not the mention the fact that it is a rolling release so one always gets the latest and greatest of everything.
