So I emailed an old college buddy who has been living in Texas for better than 20 years. What do you think of Rick Perry I asked.
The answer came back "Not much".
The friend pointed out that Texas's economic success during Perry's governorship is mostly due to vast deposits of oil and gas in Texas, rather than any particular cleverness on Perry's part.
The Texas housing market is in trouble due to crazy mortgage lending. The cost of home owner's insurance is thru the roof.
The state budget is out of balance and they have been cutting school funding despite a massive untapped rainy day fund.
There was a case called "Willingham" in which a probably innocent man has been convicted of arson and executed. Perry fired the review board.
"Perry looks good, has good hair, but a whiny wife."
He is close to the religious right, he is OK with creationism.
I've known this guy for 50 years. He is pretty level headed and an astute observer. With a recommendation like this, I don't think a wanta go with Perry.
His final comment was, "Republicans can do better."

Close encounters of the Asteroid kind
Front page of the Wall St Journal has a big drawing of asteroid 2005 YU55, which crosses earth's orbit and came within 201,000 miles of earth (inside the Moon's orbit) Pretty science fictiony for the staid old Wall St Journal.
This one missed.
Question: what should we do when we detect one that's gonna hit us? The only thing that might do some good, it to nuke it. Good big nuke, close up, might blow it into gravel. Or it might break it up into a dozen pieces. But the pieces keep coming. What causes more damage, one really big hit, or a dozen smaller hits?
Do any of those ICBM's have the oomph to boost a big nuke up that high? These asteroids are small and dark and hard to see, so they will be real close before we spot them. No time to build a special rocket, we would have to use something off the shelf. That's an ICBM that's been standing silo alert for decades. Or possibly a satellite launcher from Space-X.
If we have enough delta-V to do a rendezvous and land on the thing (heh, works in the movies) we could set a big nuke on one side of it it. Set it off, and that rock is gonna move. Trouble is, it may not move all that fast, which means we gotta nuke it when it's far out there, to give it time to move far enough to miss the earth.
Do we have any rockets with that sort of delta-V?

What do you lead with?
Tonight and last night The Newshour led with the Herman Cain sexual harassment story. Where as Fox News, put the story on "page 2", after other lead stories. Looks like the Newshour wants to torpedo Herman more than Fox does.
Internet censorship bill in Congress
US rep Lamar Smith (r -Texas) is supporting a bill to allow the Dept of Justice to shut down any website it wants to. No trial, no nothing, if DOJ wants the site off the internet, bang, it's gone.
This measure is the darling of Hollywood, 'cause they want to use it to "prevent piracy".
Rep Smith has accepted a few hundred thou from the entertainment industry.
What does it cost to buy a US congressman? Not much apparently.

Strange Obit in The Economist
The Economist wrote an obit for Dennis Ritchie, who died October 12. The obit writer was so ignorant as to fail to mention that Dennis Ritchie is the Ritchie of Kernighan and Ritchie, "The C Programming Language", a slim paperback book owned and revered by every programmer on earth. The book is so basic and so well known that it goes by the name of "K&R" in the programming world.
Then the obit writer makes a few wild claims. "C fundamentally changed the way computer programs were written". Not quite so. That honor belongs to FORTRAN which goes back to the early 1950's. FORTRAN was the first widely accepted higher level language and made portable (will run on more than one brand of computer) programs possible. It was so popular that all competing computer companies were obliged to offer a FORTRAN compiler on their machines.
C came later, 1960's, from Dennis Ritchie and Ken Thompson at Bell Labs. C caught on and became wildly popular because it was a vastly better FORTRAN than FORTRAN was. Not that C could do anything that FORTRAN couldn't do, but programming in C was infinitely easier. C swept away the myriad of pit falls, gotcha's and spaghetti coding practices of FORTRAN. I can still remember the pleasures of doing it in C after years of struggling along in FORTRAN.
C had a lot of great features, foremost among them was manual, K&R. This thin book was clear and lucid and above all short. Everything you need to know is in it, well organized and so well written you could read it for pleasure. Compared to the massive, wordy and opaque manuals that came with other computer languages, The C Programming Language was pure poetry and contributed mightily to the success of C.
Today practically all commercial programming is done in C. So in honoring Dennis Ritchie we are honoring a man who created modern computer programming, not single handedly, but with co workers. Dennis didn't do all the work, but he did do a lot of the work.

Firewall, or is it a ring fence
With Greece sliding down the tubes, and the rest of the EU running around crying out "The sky is falling, the sky is falling", newsies on NPR and at The Economist keep agitating for a "firewall" (American speak) or a "ringfence" (European speak) around Greece to "prevent the contagion from spreading".
I wonder what they are talking about? Do they mean a great big sugardaddy who will step in and guarantee that all lenders to Greece and every other shaky country will get paid off in full and nobody will ever loose any money?
That would be nice, but neither the Americans nor the Chinese have that much money, and even if they did, they are not inclined to spend it on Europe. Nobody else in the world is big enough or well heeled enough to be a creditable sugardaddy.
The fundamental problem with Greece is nobody in their right mind is gonna lend them any more money. They are broke, owe more than they can ever pay, and still want to borrow more to cover their government spending. Their economy, never very good, is not growing, and doesn't throw off enough cash to pay their way. What kind of "firewall" can change that?
Then come the other shaky European countries. They aren't as bad off as Greece, yet, but everyone of sense can see where they are headed. Already they have to pay 5 and 6 percent for money while Germany and America can borrow for under 3%. As confidence wanes, they are going to find it harder and harder to borrow money. Soon it will become impossible.
Again, what sort of "firewall" will convince people to lend to deadbeats?
Or are we just hearing naive newsie's wishing for Santa Claus?
