When Steve Jobs trashed Adobe Flash, didn't he say that Apple was going to use h.264 'cause it was an open standard. Admittedly, he was trashing Adobe in the same breath, but it seems to me that Microsoft is putting up the same sorta arguements. Both want to restrict browsers to h.264 for video. The only difference I see is that Microsoft did not bad-mouth Adobe Flash directly. That's just my opinion.

TFA does not mention tryptophan at all. TFA says lifespan increase is due to reduced calorie diet. Methionine, says TFA, was added to the diet to reverse lost fertility. TFA says, "Long life may stem from a proper imbalance of dietary nutrients" It don't say shit about restricting any amino acids to live longer. It says add one to be able to reproduce. What I read says that reduced calorie diet with some yet unknown supplement mix of vitamins and amino acids could extend lifespan.

when you are dealing with multi-year timespans where a second or two one way or the other can make a significant difference -- mainly astronomy, celestial mechanics, and satellite stuff.

Last time I had to deal with leap seconds in software, I found this: Sources for Time Zone and Daylight Saving Time Data which describes a system level time information database that includes leap seconds as well as Daylight Savings Time and time zones.

There are leap-second-aware time functions available that can be rolled into GNU C. Once they are in place, adding a leap second is a trivial sysadmin operation to update the time-info-database. Then all software using it will be correct without need to re-build or recompile.
