Firefox, in its official version, still lacks support for multi-threading (running on different processors), though Chrome and Internet Explorer 8 both have this feature. A Firefox project called Electrolysis is underway to close this gap. A blog author tested a pre-release version of Firefox that loads different tabs in parallel, and he chronicles his findings, including a huge speedup in Javascript vs. Firefox version 3.5 (though the pre-release still lags Chrome in many of the tests).

I designed/customized my laptop on 2008-09-17 and placed my order, which totaled approximately $1,700. The laptop was built and apparently shipped on 2008-09-28. Given my APO address, I know mail can sometimes take a little while to get here, though 7-10 days is normal. Dell said to give my laptop 6-8 business days and occasionally, it might take as much as 4-6 weeks. So on 2008-11-12 I sent another email to Dell informing them I still had not received my laptop. One person said to give it more time, while another person responded to my message telling me to send my address again and they would send me a replacement. So I sent my address immediately and never got a response. It is now the 30th of November and I still have no laptop and Dell seems to have quit responding to my emails. This is very frustrating being out $1,700 and not having a laptop to talk to my friends and family and do school work. Phone calls aren't easy so calling them is pretty much out of the question. Any advice on what I can or should do at this point to get the computer I ordered or get my money back?"

Nowadays, I no longer play chess; but somehow I remembered this nice little puzzle and coded a 60-line Python solver that can tackle even 100x100 boards in less than a second. Try beating this, fellow coders!"
