TheStreet.com, a financial news website, is shutting its San Francisco office, reported Portfolio.com. The announcement doesn’t say how many jobs that would mean, but surely not that many compared with the 5000 worldwide job cuts announced last week by Sun, which has its HQ in Silicon Valley. The announcement follows that of Six Apart last week, where 18 lost their jobs.

Meanwhile CNet links to who’s firing, who’s hiring.

I wonder if the folks at TheStreet.com followed the advice they printed last month about layoff do’s and don’ts.

Updated to clarify the suspect in this case was not laid off.

Friday a 47-year-old engineer who had been canned earlier in the week allegedly killed his company’s CEO, the operations VP, and the HR lady, before fleeing. Yesterday police arrested Jing Hua Wu, former test engineer at a semiconductor company called SiPort Inc. and were holding him in the Santa Clara County jail pending arraignment on three murder charges.

Update: An earlier version of this post implied that the alleged shooter might have snapped after being laid off. But a recent report on Valleywag states the suspect was fired, and that the company has never laid people off. A report on KCBS radio Monday morning said the suspect was fired for poor performance, though a profile on the station’s website still says he was laid off.

Though high gas prices and “Spare the Air” days like today have more passengers than ever riding public transit — including the ACE Train that runs from Stockton in the central valley to Silicon Valley — sometimes they can’t win for losing. Yesterday the ACE trains were threatened by the heat wave now torturing inland areas, with 110+ temperatures hot enough to warp steel rails. Train workers had to walk in front of the train to make sure the rails weren’t damaged by the heat, delaying the trains one to two hours.

At least there have been no reports of BART delays due to the heat, as in the May heat wave.
