Really nice post on the JavaScript string concatenation performance (found it because it references my string concat SpeedTrial on mckoss.com).

Interesting bit here is the analysis of the Firefox code AND THEN an even better improvement in the reallocation strategy to get 20x the performance.

Obama on algorithms ... gotta be the first time any political candidate has used the term "bubble sort", EVER.

Quoted: The proceedings at Google are not unremittingly serious affairs. Mr. Schmidt asked Senator McCain, “How do you determine good ways of sorting one million 32-bit integers in two megabytes of RAM?” Immediately signaling that the question was asked in jest, Mr. Schmidt moved on. Six months later, Senator Obama faced the same question, but his staff had prepared him. When he replied in fluent tech-speak (“A bubble sort is the wrong way to go”), the quip brought down the house.

Feb 2007 article on a new algorithm for automatically clustering (classifying) large data sets. Lots of applications in search, recommendation engines, social networks, etc.

Later claims later appeared in Science Magazine that the affinity propagation (AP) algorithm is not 100x as fast as prior know algorithms.

Quoted: Kalman Filter

Really insightful article about the difficulties of writing correct software - particularly in the realm of numerical calculation.

Also references an Excel 2007 calculation (display) error where the formula 850*77.1 is displayed as 100,000 (instead of 65,535)!
