I have the 64 bit version of R compiled from source on my Ubuntu laptop. I recently had a need for R based on 32 bit since a package I needed to compile and use only works in 32 bit. I thought it was readily available on Ubuntu since both 32 bit and 64 bit… Read more »
The following are notes for myself. I like to use the bleeding edge version of R: svn checkout https://svn.r-project.org/R/trunk/ r-devel cd r-devel ./tools/rsync-recommended ## use the following to update sources: svn update ## pre-reqs sudo apt-get build-dep r-base #sudo apt-get install gcc g++ gfortran libreadline-dev libx11-dev xorg-dev #sudo apt-get install texlive texinfo ./configure make sudo… Read more »

Amazon Web Services offer a free usage tier of EC2 cloud service for 1 year. After the 1 year, the micro instance cost about $.02/hr, which is… Read more »

This is what I envision the future of computing to be if things were up to me. I can turn on any computer and be able to access an environment that has all the applications I use via a web login. That is, I should be able to remotely log in to my computer/server from… Read more »

stumpwm is to window managing (tiling?) system what emacs is to text editing and conkeror is to web browsing. very cool. if i was on a linux laptop/desktop like i used to be, i would definitely use this. i’m even debating on quitting my mac os x for this (with emacs and conkeror). however, i… Read more »
