The last couple of days I've been getting phone calls from insurance agents wanting to talk to my wife. There got to be so many of them I started to wonder what was going on. When I inquired, the agent of the moment tells me that my wife had requested an auto insurance quote. Well, that's weird. When I tell my wife about this she denies ever asking for anyone for such a thing.
The number of calls and emails from headhunters have also jumped up, which makes me think somebody tickled my file. Could all this have been triggered by the North Korean hack attack on SONY?
Meanwhile, back at the ranch, blogger has changed their 'I am not a robot' test. Used to be you had to type in some numbers or letters that only a true human [tm] could decipher from a picture. Now all you have to do is check the box. Curiously, the box is not a picture but an html construct. What you see above were cropped from screen shots.
Chromebook bonus: you can crop the screenshot when you make it, you don't need to take separate step. Magic key combination: ctrl-shift + funny square light bulb lying on its side symbol, right above the six key. Now where do I find the icon for that key? And what is it supposed to be?

Bought this book on a recommendation. Showed up in a padded envelope yesterday. The package was so thin I didn't imagine it could be a book, but here it is. Look at the price on the cover: 35 cents! How old is this thing? Written in 1952, this copy printed in 1957. It is basically intact, but the pages are thoroughly yellowed. I don't expect it to survive much longer.
|Dollar mouse shipped direct to my house from Singapore|
It worked fine for a while, but then it started acting really flakey and I thought, well, what did you expect for a dollar? But then it went back to working okay, and then it went to being flakey again, and this time I realized it was because my left hand was reaching across the keyboard to the number 8 and 9 keys and I was letting my hand rest on the touch pad. So, nothing wrong with mouse, it's just the touch pad giving me trouble. Again.
Big advantage of mouse over touchpad: right click. There's probably some key combination that will allow you to preform the same function with the touchpad, or there might be some magic finger gesture you can make, but you know what? I don't care. I have a mouse and I know how to use it so that's what I am going to do.
|Bill is... concerned, about this reentry trajectory.|

The big factors affecting reentry are the time when fire your retro-rockets, and how much you slow down. You want to be accurate about this because a little too much or too little, too soon or too late, can easily kill you. But after you've fired the retro-rockets there isn't much you can do except pray.
Except I seem to recall something about Orion being able to adjust it's attitude, which could easily affect it's trajectory, except how can you tell? GPS will be useless as the fireball you generate as you plunge into the atmosphere pretty much ruins any chance to sending or receiving any radio communications. Well, how about inertial guidance? That used to require big heavy chunks of equipment that was marginally accurate and marginally reliable, but I think we've gotten better at it. So it's not inconceivable that Orion was able to steer itself quite accurately.
Once you deploy the parachutes, you kind of lose your steering capability, but you also become much more visible, so the pickup crew should be able to find you. As if they haven't been tracking you on radar since you appeared over the horizon ten minutes ago.
This video has some odd bits, but it also has some good shots.
Other posts about Orion. Most of them are about the spaceship, only a couple are about the airplane.

|Cuba Police Woman|
It's about god damn time we normalized relations with Cuba. Anyone who disagrees is either a moron or is in cahoots with the Mafia (that covers at least half the people in this country). The Google has all the links I could want about the Mafia in Cuba. Remember, the Mafia killed Kennedy.
Some people say we shouldn't be dealing with a police state like Cuba. I say that's a little like the pot calling the kettle black. We have the biggest security organization in the world. OK, China's is probably bigger in terms of manpower, but ours is no slouch. Future wars are going to be cyber-wars fought by secret security organizations. Terrorists just serve to keep people distracted while the king monkeys steal all the monkey biscuits.
P.S. North Korean leadership has no sense of humor. Wait, that can't be true, everyone has a sense of humor. I wonder what makes them laugh? I'll bet seeing SONY fall on their face got a few chuckles out of them.
