Jerry Pournelle

He’s posted a brief but complimentary review of the book (it’s buried deep in the post, after his lengthy discussion of his computer tech upgrades):

Safe Is Not An Option, by Rand Simberg is a reliability expert’s look at the space program. The book is discussed at length on its own web site. Those interested in the space program should read it: the book is quite critical of current space policies. It has endorsements from both astronauts and space policy analysts.

His general thesis is that NASA’s obsession, born of the days when “ours always blow up” and brought back with a vengeance by the Challenger disaster, is eliminating all human risk from spaceflight. That doesn’t work and the obsession is a huge obstacle to progress. There will always be risks, and we will always have heroes.

Simberg is an aerospace engineer with considerable experience and his analyses of various space incidents such as the Challenger Disaster are spot on, which is to say, I agree with them. Recommended.

Thanks!

Coffee

Is it ruining your productivity?

In other words, that euphoric short-term state that you enter after drinking coffee is what non-habitual caffeine consumers are experiencing all of the time. The difference is that for coffee drinkers, the feeling doesn’t last. “Coming off caffeine reduces your cognitive performance and has a negative impact on your mood. The only way to get back to normal is to drink caffeine, and when you do drink it, you feel like it’s taking you to new heights,” Bradberry explained. “In reality, the caffeine is just taking your performance back to normal for a short period.”

See, for me, the thing is that I can’t even tell whether or not I’ve had any. I just drink it for medicinal purposes. In fact, even though I now drink two cups almost every morning, I don’t consider myself a “habitual” drinker, because that implies that it’s a habit. It really isn’t, for me. I sometimes forget to drink it.
