That Violet Blue thing

WW/.D?

Personally, it bothered me way more when Joel had his stupid moment and forgot what a 'circuit' is.

Journalists debate the should-we-or-shouldn't-we-publish question. Nerds flagellate themselves over errors of fact that make them look stupid.

In terms of feedback modifying editorial control, I think the reaction on ./ to a cute Youtube video post was way more important than this incident.

I read BB, and will continue to do so, because it applies the "Lesson of Usenet"--that moderators and editors are useful--in a way that makes the signal-to-noise ratio high enough to be worth my time.

I wouldn't be as generous as other people. If you're going to give out grades, you ought to know what the correct answers are. I'd give this list an 'F'.

The experiment of exposing humans to vacuum has been performed on occasion, and the answer "where the ship's crew is exposed to vacuum should kill everyone instantly" is clearly wrong.

This link has a nice summary of the effects of exposure to vacuum:

Including this wonderful tidbit:
"the person later said that his last memory was of the saliva on his tongue starting to boil."

I really enjoyed walking barefoot across burning coals.

HOWTO Make a magic fireball (flaming oily rag) -- UPDATED

Like CPT. TIM, I often used to use rubbing alcohol to set my hand on fire. The only time I burned myself: after using my burning hand to light a propane balloon that I held with my other hand, I got distracted by audience reaction and forgot my hand was still on fire.

I'm not sure if my hands are insensitive to heat because I do lots of things like that, or I do lots of things like that because my hands are insensitive to heat.

There have been times I've burned myself, and the first indication was the sound or the smell. I have learned to recognize the 'slippery' feeling of very hot metal, and this has saved me from a burn many times.

(And in case you're wondering, the only scar visible on my hands was from a cut, not a burn.)

Can't wait to make some of these balls and play with them.
