Donald Ka-NOOTH and the Art Of Computer Programming

Anyone involved in computer programming should be familiar with the works of Donald Knuth (the K is hard and the name is pronounced Ka-Nooth).  If not, the New York Times can remedy that, having recently published a profile on Knuth titled The Yoda of Silicon Valley.
Wise he is.  Show he does, the dark and light arts of algorithms:
Volume 1: Fundamental Algorithms Volume 2: Semi-numerical Algorithms Volume 3: Sorting and Searching Volume 4A: Combinatorial Algorithms
A very important concept, however, can be found in the title.  While students study computer science, Knuth reminds us it's still an art.  In that sense, I would compare his books to the collected works of Shakespeare -- creative, insightful, but difficult to read and better understood in a study group or book club.  Whether Knuth or Shakespeare, their works are rarely read in their entirety, but their impact can still be felt throughout society.
Programming is a science, but it is apart from the natural sciences like…

On their website, I looked up my model and purchased the appropriate battery, along with the Apple specific tools I needed to complete the swap.  I also found well written tutorials, a difficulty rating, and feedback from other do-it-yourselfers.  This battery replacement was easy and at $102.89, cost effective.

My MacBook Pro now has power to w…
