Honest plotting

There are a lot of ways to fiddle with a line graph to alter the message. One common trick is to mess with the vertical axis. By rights, the vertical axis ought to go down to zero so you can see the magnitude of the line. Plenty of plotters, and a lot of plot software, set the vertical axis to start at the minimum data point and stop at the max data point. It is claimed that this shows more detail in the data. Yeah, I suppose. It also has the effect of making a very slight change look a helova lot bigger. I consider that misleading.
I notice the global warmers always blow their plots up vertically as much as possible.

Profiling is a thought crime

So what is a TSA screener supposed to do when he sees a young, male, bearded, robed, passenger going thru? Treat him the same as the little old lady next in line? Check him out a little more? The young Islamic men who get their bags hand searched will complain they were "profiled", by which they mean they were subjected to extra screening for the wrong reasons. They will claim they are being picked on because of their race (skin tone actually), sex, religion, national origin or something or other. It's not what was done, it's the motivation behind it, which makes the accusation of profiling an accusation of a thought crime. The TSA screener was thinking wrong thoughts.
I don't like thought crimes. What a person thinks is his own business. And short of mind reading, there is no way of knowing what some one thinks. We can outlaw actions, we shouldn't outlaw thinking.
In actual fact, they were screened 'cause they looked suspicious. Most of them could avoid the extra hassle if they purchased tickets in advance, dressed appropriately, groomed themselves properly, and avoided speaking in foreign languages. The nail that sticks up gets hammered down.

Competition or FCC to "regulate" online search?

The FCC, founded in the 1930's to assign frequencies to radio broadcasters and do price fixing for the telephone company, wants to expand. They want to regulate Google and make it "fairer". They are supported by loads of webbies who feel their websites arn't getting good positioning on Google.
Google has competitors. If Google's service and site rankings don't please the web surfing public, they can and will go elsewhere. That's all the regulation needed. I see no reason to give FCC bureaucrats a say-so in how a search engine ranks websites. In fact, that could get scary, the current FCC would tell Google to rank Democratic sites above Republican sites.

It's the crotch bomber.

ABC has a picture of the infamous bomb. It was 80 grams of PETN fixed in the bomber's jockey shorts, right between his legs. If it had detonated, the bomber would be unable to enjoy the 72 virgins promised to jehadi warriors in paradise.
Pat down searches for this kinda bomb will be embarrassing for all concerned.

The ABC story claimed that 80 grams (about 1/6 pound) could "blow a hole" in an airliner. Fortunately, well built jetliners can continue flying with a hole blown in them. 80 grams isn't much. Air to air missiles carry much bigger warheads (5 pounds) and do not always bring down their target.
I remember an F105 jet fighter that took a missile hit in the tail. Heat seeking North VietNamese missile flew right up the tail pipe and exploded. Blew the crap out of the tail section, but the aircraft returned safely to base. The engine kept running, and the rudder and elevons kept working.
I don't believe a crotch bomb has enough power to crash a Boeing jetliner.

What's the difference between a database and the circular file?

What's-his-face Obama's press secretary was on this morning explaining about how they let the leg bomber on the plane. The government has a 500,000 name data base containing derogatory information. The leg bomber's father called the US embassy to warn us about his son's radicalization. The embassy entered the leg bomber's name into the 500,000 name data base. This ain't much different from putting the name into the circular file.

Words of the Weasel Part XIII

Mitigation. When something goes wrong we don't fix the problem, we mitigate it. We create a "mitigation plan" . Which looks real good in the cover-your-ass file after the disaster. The Sunday pundits were grilling Janet Nepoliotano about the leg bomber this morning. She explained the government had a mitigation plan and exercised it. Which is easier to say than to explain how that turkey got on the plane with a bomb strapped to his leg.

Leg Bomber

The Christmas day story of a Nigerian attempting to bring down a Northwest Airlines flight with a bomb strapped to his leg is going around. Question. Would the leg bomb have enough power to destroy a Boeing airliner?
By the way, I hope the burns the leg bomber received hurt a lot.
