Ignition! wrote:It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.

The cylinder had been cooled with dry ice to make it easier to load the material into it, and the cold had apparently embrittled the steel. For as they were maneuvering the cylinder onto a dolly, it split and dumped one ton of chlorine trifluoride onto the floor. It chewed its way through twelve inches of concrete and dug a threefoot hole in the gravel underneath, filled the place with fumes which corroded everything in sight, and, in general, made one hell of a mess. Civil Defense turned out, and started to evacuate the neighborhood, and to put it mildly, there was quite a brouhaha before things quieted down. Miraculously, nobody was killed, but there was one casualty — the man who had been steadying the cylinder when it split. He was found some five hundred feet away, where he had reached Mach 2 and was still picking up speed when he was stopped by a heart attack.

WTF? 2 wired mice available and they were both the ultra cheap crappy store brand. Whatever happened? I've got one from Amazon coming in now.

Best Buy has been basically worthless for computer stuff for several years now. IIRC the only computer gear I've bought there in the past ~5 years was a pair of hard drives at the height of the hard drive shortage (Thailand floods). It took Best Buy a long time to adjust their pricing to reflect market conditions, so they were still selling drives at pre-flood prices for several weeks.
Pretty much the only thing Best Buy is any good for these days is kitchen appliances. Need a new Kitchenaid mixer? They've got those in all the colors!
I bought the Anker gaming mouse from amazon after my RAT Cyborg crapped the bed after just a little over a year. The Anket was $40, feels fantastic in hand, has all the bells and whistles I want, and I feel like it's a very high quality device. The software for it is nice too. Lots of easy to record macros, buttons, even change the light color with it. I really like this mouse.paulWTAMU wrote:Also, Oh man, they have done horrible things to the PC selection at Best Buy.

I posted about this a few months ago, and it's still going. XKCD #1190 has been changing every hour, on the hour (every half-hour initially), since late March.
This site lets you watch the entire sequence -- with pause/forward/back capability -- in its entirety.
Note: The current frame, as of 9:47 CDT, is all black... a "fade to black" between scenes of sorts. You can hit the second link above and use the left-arrow key to move back through the last few hours/days worth of frames (it wraps around) if you want to get a feel for the recent history... or just let the aubronwood site load and free-run to get the whole sequence from the start.

Soon to come are random drives down dirt roads with the trees all in fall colors and apple-picking season. We've made it through the dog days and the climate is now moving to the part of the year where I don't complain about it (even if I wake up in January to find 24" of "climate" in my driveway).
If I remember I'll grab the dSLR and show y'all why I live in and love this state. Vids would need to come from the aged phone, though.
