Or so thinks The Economist. I don't think so myself. Universal Serial Bus was added to computers not so long ago, claiming to replace the multitude of special connectors (keyboard, mouse, printer port, RS232 serial port, mike and speaker plug) with one size to fit all USB connector. It's done fairly well on the computer front, all computers have some now. As a side effect, USB will furnish very modest amounts of low voltage DC power so the low draw things like mice can omit the customary "wall wart" power supply.
Cell phone makers have started offering USB cables to allow recharging of cell phones off computers. Which makes a certain amount of sense, computers are everywhere, and with USB you can recharge on the road and only have to carry a cord, rather than a heavy little wall wart.
Groovy and all. The Economist hails this development as a major break thru in energy conservation, claiming that the hi tech power supply of the PC saves juice compared to the "always on" wall wart left plugged in all day.
Not really. At least not in the real world. We are talking about nit noy amounts of power here. USB only supplies 10 watts. Compared to the current draw of air conditioners, stoves, water heaters, clothes driers, oil burners, and TV sets, 10 watts is nothing. Ten watts left on for an entire month is only 7 kilowatts hours. My clothes drier uses that much juice to dry just ONE load of wash.
Methinks The Economist needs to consult a real electrician.

Five million lines of code
Fox News just reported that the Obamacare website contains five million lines of code. Wow. Old rule of thumb, a programmer can produce 10 lines of code a day. So, five million lines of code, is 500,000 mandays, or 2000 man years. ie, one man for 2000 years, 2000 men for one year, or any combination in between. Wow. We know they only spent a year or so on the job. Which means a 1000 man project at least, which is a night mare. To get any good out of 1000 programmers, you have to divvy up the job into 1000 pieces, and give each man one piece to code. In order for the 1000 pieces to work together, you have to write a spec for the inputs and outputs of each piece. That's a 1000 specs. And then someone (a small army actually) has to make sure that the output specs all match the input specs and vice versa.
Let's see, a manyear costs at least $100,000 for experienced programmers, so 2000 manyears is only $200 million. The TV news says Obama spent $632 million on the job. I wonder where the other $400 and some million went.
Incidentally, five million lines of code sounds awfully high. Like maybe made up by newsies. Just as an off-the-wall guesstimate, ( my day job used to be estimating this kinda thing ) I would think 100,000 lines of code would be plenty to do health insurance signup.

Europeans can over regulate with the best of 'em
According to The Economist, the EU has regulations limiting/forbidding subsidies to airports from local/national governments. You have to wonder why. If cities/provinces/countries want to spend taxpayer money on airports, why not? What business is this of the EU?
The urge to get an airport is understandable. No business is going to locate in a place without air service. You need air service to get your salesman out to customers, your customers in to your plant, your servicemen out to customer sites, and overnight air parcel delivery for crucial spare parts. Manchester Regional Airport NH is a good example, a vast network of businesses in New Hampshire depend upon flying out of Manchester. In fact the place had the chutzpah to re name itself Manchester-Boston Regional a little while ago. I don't know just how much taxpayer money went into that airport, but that new exit for the airport we put on I93 last year wasn't cheap.
Anyhow, the urge to get airports is understandable. And I don't see any reason to regulate it.
But, read on. The subsidized airports have lower landing fees, which attracts low cost carriers like RyanAir. The European legacy carriers mostly fly the big airports, and they see the low cost carriers eating into their business, "stealing passengers" from them.
So, the EU regulations are really crony capitalism, the big boys attempting to squash the upstart newcomers.
I'm sure the Obama administration is watching this one.

The History Channel and the Crystal Skull
I saw the movie, actually Indiana Jones and the Crystal Skull. Fun flick with some good scenes, like Harrison Ford and Shia LeBeouf riding a Harley thru the Yale library reading room. Later they discover an alien crystal skull which becomes a clue that leads them to lost cities and so on. Great movie prop. I had never heard of crystal skulls before and I assumed it was a product of Spielburg's fertile imagination.
So the other night I am channel surfing and on The History Channel I find a "serious" documentary on crystal skulls. Ten of them are known, the show had some pictures, and claimed that one had been scientifically analysed. Groovy.
Of course the show didn't say whether these skulls had been discovered before or after the Spielburg movie. Nor did it say what the "scientific analysis" had discovered. For openers, what was it made of? Quartz? Glass? Calcite? Rock salt? Lucite? The History Channel was less convincing than the Spielburg movie.

Airbus wins Japan Airlines Order
Japan Airlines just signed a deal to buy 31 A350 airliners from Airbus. At $200 million each, this is $12 billon in sales, quite a chunk of change. The A350 is so new it just made it's first test flight this summer and has a year or two of testing and certification before it can be delivered. It's carbon fiber (fiberglass) construction, intended to compete with Boeing's 787. Boeing could have had this sale, if their 787 had not been so late, and if it hadn't had those battery fires. Up until now, Japanese airlines were all Boeing fleets, Boeing and the Japanese industry had numerous joint ventures and cross sales arrangements. Now that JAL has bought Airbus, the other Japanese carriers are expected to follow suit.
Aviation Week credits the Airbus sale to effective work by top Airbus executives, Leahy (no first name given) Head of Sales, and Fabrice Bregier, CEO. They also mention JAL's new chairman, Kazuo Inamori saying that an airline as big as JAL ought to have more than one supplier. Which is true.
Also interesting is the backlog of Airbus A350 and Boeing 787 orders. Although Boeing has 979 orders for 787's, Airbus is running hard with 725 orders for the A350. Each backlog represents about $2 trillion dollars worth of business. Staggering.

Obamacare computer crashes
Putting up a website that can handle the load of every family in the country is difficult. The way to make it happen is let the contract to a company that has done such a website before. Anyone, except perhaps community organizers should know this.
Apparently Obama didn't know this, and gave the contract to some crony that has no industry rep. And, surprise, surprise, it doesn't work. That's the thing about contracting. You never know if the contractor is competent. But competent or incompetent, the contractor will spend all the money.
They should have given the job to someone like Google, Apple, Yahoo, Microsoft, Amazon, Facebook. But they didn't.

Main Stream Media, do we care?
Everyone agrees,. the mainstream media is in the tank for Obama and the Democrats. But really? Sure, the NY Times , the WashPost, the traditional TV networks, the AP, and a lot of others are Democratic house organs. But, Fox News, the Wall St Journal, talk radio, and the blogosphere are Obama hostile. Fox News owns the airwaves (cable waves now-a-days), The Journal is distributed coast to coast and outsells the NY Times by 4:1. Rush Limbaugh still has a huge listener base. The blogosphere is rising in influence and importance. Obama was railing against "lobbyists and bloggers" just the other day. As a blogger I'm flattered to get a mention, and scared that Obama may sick the IRS (or worse) on me.
The Democrats have mass, but the Republicans hold the quality edge.
