### The R Project for Statistical Computing

Linux and Apache may get all the limelight, but there are other open-source projects out there that are truly impressive. One such effort is the R Project, which is essentially an alternative implementation of the S language and environment, the best known implementation of which is S-PLUS. If you're the sort of person who needs to carry out the odd bit of hypothesis testing, time-series analysis, regression or analysis of variance (ANOVA), I'd heartily recommend taking a look at R before parting with hundreds of dollars for S-PLUS: you'd be surprised just how much you can do with this piece of software. Heck, there are actually things one can do with R that simply can't be done with its extremely expensive sibling.
