Global Warming Data hacked

Some 61 megabytes of data, computer programs and emails was extracted from Britain's Hadley climate research unit and posted on the internet a couple of days ago. The Hadley troops have admitted to the data loss. This blog posts a very damning email admitting to data fudging to avoid showing a temperature decrease. The blog goes on to explain how the data was being "smoothed" to make it "look better".
Smoothing data by computer used to be my day job, so I know a little about it. The discussion in the blog makes no sense at all to me. "Smoothing" can be abused to create "trends" where no real trend is present. I think this true of the Hadley data.
The amount of global warming detected by the warming true believers is only a fraction of a degree. The raw data jumps around more than that. In short, the global warming is not really visible in the raw data, only after the data is "smoothed" heavily does a tiny trend emerge.
It's always best to look at the raw data, on a graph. The human eye is superb at detecting tiny trends. If you cannot see trend by eye looking at the raw data, the trend probably doesn't exist.

Innumeracy and Mammograms

Quite a bit of heat, but little light, has come from the government's recent declaration that yearly mammograms are no longer necessary for women under fifty. Neither side has shown any numbers defending or attacking the proposition. How about some graphs showing deaths from breast cancer over the years, number of breast removals, number of less drastic treatments, survival rates after treatment, number of mammograms administered, number of false positives for mammograms, false positives from breast self examination, number of breast cancers detected by mammograms, number detected by other means.
The proposition that yearly mammograms after age 40 saves lives, and/or reduces breast removals, is a numerical proposition, and the advocates on either side could strengthen their arguments with some numbers. If the numbers cannot be found, perhaps a study could be funded.
So far the public debate has been number free.
Probably because reporters are innumerate.

In Fed We Trust by David Wessel

Good read. Blow by blow account of the Fed and the Treasury reacting too, and dealing with, the onset of Great Depression II last year. Describes how Bear Stearns, Lehman, Merrill Lynch, and AIG failed, and the decisions to bail them out (all except Lehman that is). The story is told largely from the Fed's point of view. Essentially the senior government money men, Hank Paulson at Treasury and Ben Bernanke at the Fed feared total system collapse and decided to pour in taxpayer money to keep the system afloat. Much as they would have enjoyed watching the stupids go broke, they didn't dare, for fear the country would be thrown into a bottomless economic disaster. At first Paulson and Bernanke used Fed money. By fall things were so bad that they went to Congress for the $750 billion TARP appropriation. As Wessel tells it, things were so bad that fall that Congress passed the TARP within days. The money guys walked into the room and said Great Depression II would start next week without TARP, and Congress believed them.
The writer is a Wall St Journal reporter, so he knows some of the stuff. The weakness of the book is the failure to describe why these enormous financial companies failed. What killed them? For instance Lehman folded up after rumors of insolvency ran around Wall St and nobody would loan them any more money. He doesn't tell us how the rumor got out, how it spread. What mistakes did Lehman make that turned them into a pariah? Was it mortgage backed securities? Credit default swaps? some big loan going sour? Bad karma? Wessel is silent in this most interesting aspect of the disaster.

GM lost $5000 per Saab sold for the last 8 years.

From The Truth About Cars. GM senior management had brains made of solid concrete. Buying into SAAB was a dumb idea in the first place, and running it at a loss for 8 years is even dumber. SAAB made an interesting niche car that had a loyal fan base. But you can't make money on niche cars. They don't have the sale volume to afford the mass production tooling needed to get the cost down to compete with real volume makers like Toyota. If they reduce costs by replacing expensive handmade European engines (and other items) with nice cheap dependable Detroit production line V-8's the loyal fan base stops buying, insulted by the presence of mass produced Detroit iron in their beloved European hot rods. It's a no win situation for a US company buying a European luxury maker. If US management had been real car people they would have understood this and saved their money. But at GM senior management is all bean counters and MBA's.
Ford made the same mistake getting mixed up with Jaguar. But Ford brought in a savvy CEO (Mullaly from Boeing). He figured out that Jaguar and Volvo were losers and was able to sell them back before Great Depression II made raising money for takeovers impossible.

It ain't political correctness, it's ultimate job security

So why wasn't something done about Major Hasan before he ran amok at Fort Hood. How about excessive job security that makes it impossible to fire anyone short of a felony conviction? Back when I was in USAF we had GS civil servant types who did nothing but cash their paychecks, substandard enlisted men who were just a burden on the unit, and marginal officers who just slowed things down.
No way could we get rid of any of these jokers. Unless you got 'em a felony conviction, you were stuck with them, forever.
Even if FBI and NSA had shared Major Hasan's emails to Yemen with his Army superior, the only thing that superior could do is write Major Hasan a bad Officer Effectiveness Report (OER) that might deny him a future promotion.
Since Hasan seems to have made major recently, looks like not even that slap on the wrist was administered.
In fact, we ought to be demanding publication of Major Hasan's OER's. Let's see what his superiors thought of him over his service career.

Economical Health Insurance insurance taxed

The most economical health insurance comes from your employer. It's good stuff, pays for everything for you and your family, and only costs a few bucks in co pays. Unbeatable.
However if you are self employed, un employed, or work for a small place that doesn't do health care, things get expensive fast. The insurance companies want about $12,000 a year for that kind of coverage. That's new car money, every year.
A better deal is "major medical" or "hospitalization" insurance. It doesn't pay for everything, just the break the bank stuff. You pay for everything else, office visits, prescription drugs, CAT scans, out of pocket. It's a good deal. The insurance only costs $3000 a year, leaving you with $9000 savings to cover the out of pocket stuff. Unless your health is really really bad, you won't spend $9000 a year.
Obamacare outlaws "major medical" insurance. Under Obamacare all insurance policies must be the $12,000 cover everything kind. If you don't buy it, Obamacare will sock you with a $2500 a year fine. In short, the Volkswagen health plans get taxed right along with the Cadillac health plans.

So what is wrong with a few show trials?

The Obama administration's decision to try Khalid Sheik Mohammad and four henchmen in federal court in NYC has provoked a lot of criticism/comment. The idea is derided as a "show trial".
Got news for you newies. The purpose of a public trial is to show that the bastard is guilty so people feel right about hanging him. This goes way back, thousands of years. If you don't bother to show the bastard is guilty, the bastard's friends and relatives will start up a blood feud.
So let's have a show trial. Should have done it years ago. Let's hope the US judiciary understands their duty and makes a decent job of it. Lots of testimony from grieving loved ones. Ugly pictures of smashed bodies and people jumping to avoid the flames. Introduce every sort of derogatory evidence. Allow recorded testimony. Don't rule out incriminating evidence just because the accused was made a little uncomfortable in the course of gathering said evidence. Deny defense requests for classified information. Trial conducted in English, with on-line translation into Arabic, by our translators, not Al Jazeera's translators. Don't allow the accused to make speeches, limit him to answering questions put to him by counsel.
Get it moving, and don't waste time. This kind of show is good for a week or two on TV. Don't drag it out like the OJ trial.
Keep in mind that the purpose of this trial is to convince the entire world that the bastard is really really guilty.
