Make Safari behave as Firefox

October 2, 2009 | [email protected]

Some weeks ago I switched from Firefox to Safari. While Safari is -- in my experience -- quicker, better looking, and has Top Sites, I was also missing some functionality of firefox. To be more precise, I missed the 'search when start typing' option, a... [Read more...]

Labeled outliers in R boxplot

April 13, 2009 | [email protected]
