Pediatrics scores again

This in from NPR.  The pediatrics association is now advising doctors to lay off the antibiotics for childhood ear infections.   They claim the ear infection often clears up by it self, the antibiotics can lead to upset stomaches, and overuse of antibiotics is breeding up generations of drug resistant super bugs.
  Right.  So kiss goodbye to that pink bottle of amoxcylin in the fridge. 
  And, speaking from personal experience, those ear infections REALLY hurt bad.  And kids get a LOT of them.  Like at least once a winter until they grow out of them.  And the antibiotics make the hurt go away within hours, not days.  And compared to the pain of an ear infection, upset stomach is a none starter.  And in a country that routine feeds antibiotics to farm animals to make them gain weight faster, don't worry about the small amount of antibiotics given to small children.

Virus Hunting

    Where do you look for virii?  Simple, you look in computer memory (RAM).  Computer programs of any kind have to be loaded into memory to work at all.  Windows uses the name "Process" for each  piece of programming loaded into RAM.   Process Explorer is a freeware program that lists all the processes loaded into memory.  It can be downloaded from the web.  Just Google for "Process Explorer" to find a site to down load it from.
    When running, Process Explorer displays a list of all programs loaded in memory, and thus runnable.  A typical computer will have about 30 processes loaded.  Most of these processes are parts of Windows and are supposed to be there.  But if you have a virus, it will show up in the Process Explorer. 
   So how does one tell the harmless and necessary parts of Windows from virii?  Just right click on the process name and Process Explorer will Bing (Microsoft's Google competitor) the internet for information on the program name.  Cool.  You will get dozens of hits on every process name.
   You want to read a number of them.  Many of the hits are from websites offering magical Windows Washing programs.  I don't trust  magical Windows Washers, they can be virii themselves, or they can break your computer.  But postings from Microsoft.com, Da Tech Guy, Bleeping Computer, CNET and many others are reliable.  Take a preponderance of evidence.  If all the posts say it's part of windows, or all the posts say it's a virus, you know where you are at.  If most of the posts are wishy-washy, and the single post that calls it a virus sounds like a rant,  then it means no one really knows what it is. 
  So what do you do when you find a virus lurking in RAM?  It only gets into RAM by loading itself off disk at boot time.  You have to use Windows Explorer to find it on disk and zap it. In fact just to make sure it's really gone, I'd empty the trash after deleting the file. 
   This is hand-to-hand virus fighting.  You only need get  into this sort of thing after your anti virus program[s] have failed to kill.

Radioactive waste leaks

News is full of talk about tanks of liquid radioactive waste leaking at Hanford.  So why don't they bring in some new tanks and pump out the leaking tanks?   If the local tank store is out of stock, how about using some railroad tank cars?  Or highway tank trucks?  Ought to be able to scare up something in a day or so. 
  No talk about doing anything about the leaks.  Instead we hear soothing talk about no hazard to human health. 
  I'm glad Hanford on on the other side of the country from me. 

Guns for Newbies

Been a lotta talk going around about this, up to and including Joe Biden  (he likes shotguns).  Long post on one of my favorite blogs, all about various calibers, stopping power, full of recommendations by name of obscure guns I barely even heard of.  The kind of jargon that goes well in gun magazines.  So, here are my recommendations for the total newbie (doesn't own a gun, hasn't fired and gun, doesn't watch many action adventure movies). 
   Get one that you can shoot well.  A .22 caliber hit beats a .44 caliber miss.  The bigger guns are more more likely to kill your target, if you can hit said target.  Bigger means heavier, harder to hold steady, kicks harder and has a louder report, all of which add up to harder to shoot.  Compromise on something you can shoot well, rather than a Dirty Harry style hand cannon. 
   Handguns are convenient, fit nicely into a drawer, a purse or a glove compartment.  It is also VERY difficult to hit anything with a handgun, even at very short range.  Long guns are much easier to aim and get hits with.  They are also more powerful than handguns, a hit with a rifle or a shotgun is much more likely to kill your opponent than a hit with a handgun.
    To do any good, you have to figure on doing some practice shooting.  You need to practice long enough to keep all your shots inside a 10 inch circle.  (At 25 yards with a handgun, at 100 yards with a rifle).  Always wear ear defenders when shooting, they will improve your accuracy.  The report of a gun is so loud it scares most of us, and the scare makes us jerk the trigger when we should be gently squeezing it.  Shooters call this condition "flinching".  Once a flinch is learned, it's hard to overcome.  Ear defenders muffle the report enough to prevent a flinch from developing in the first place.
  The fit of a hand gun to your hand is very important.  The right fit prevents the grip from twisting or sliding in your hand as the gun is fired, which makes the second shot more likely to go where you want it to go.  A regular sized handgun is easier to shoot.  The little snub nose jobs are harder to aim (and grasp).  You really have to shoot a handgun to know if you are going to like it.
   Revolvers are more dependable than automatic pistols.  Revolvers have no safeties to forget, need little lubrication and have no springs under compression waiting to break.  Just pull the trigger and a revolver goes bang.  Automatics not so good.  American Rifleman magazine did a comparison shopping piece on small automatic pistols not long ago.  For each gun reviewed, they listed the number of times it jammed while shooting it.  Stick with a revolver.

How to revise our military procurment

According to Aviation Week that is.  Everyone knows that US military procurement is a mess.  It takes too long, puts on too much gold plate, and costs too much.  Aviation Week has been around a long time and knows the ins and outs of procurement and where the bodies are buried.  They have five recommendations for improvement.

1.  Permit the few remaining prime contractors to merge.  There aren't many left, (Boeing, Lockheed-Martin, and Northrup-Grumman?).  They would all merge together in a heartbeat if the government would let them.  Downside for us taxpayers, no more competitive bids, there would be only one qualified bidder on all jobs.  The industry would love that.

2. Drop the 8(a) goals for small and disadvantaged defense contractors.  This is the first time I heard of this one.  Sounds like crony capitalism at work for favored contractors.

3.  Drop the 50-50 rule requiring half of military maintainance to go thru the military depots.  Good idea.  Air Force depots were huge, slow, and did terrible work.  Plenty of stuff shipped to us from depot was defective on arrival.  Repair work ought to be done on a competitive bid basis. Low bidder gets the job.  If the depot can bid low  fine, if not (the likely case) private industry gets the work.

4.  Publish an official list of critical future technologies, cyber warfare, UAV's, reconnaisance, etc.  Not sure if this is so critical.  Sounds like a plea for the government to convince industry suits to back certain projects. Not sure if that's such a good idea.  A government list is no more likely to be right than an industry list. 

5. Make the loser pay in contract award disputes.  It takes for every to get a project going, 'cause no matter what the contract awarding agency does, figure that the loser will sue just on general principles.  That's gotta add a couple of years delay on every job.  If the loser had to pay court costs, he would be less willing to sue, or at least only sue when he had a strong case. 

Well, I can go alone with numbers 2,3, and 5.  I am against  number1.  Number 4 doesn't strike me as terribly important.

Cannon Mt Ski Weather

Good.  Very Good.  We got 2-3 inches last night, and 2-3 inches the night before.  Today the sun is out and the temperature in mid to upper 20's.  Perfect for skiing.  Trails are all in good shape.  More snow is forecast for the weekend.

Lithium Batteries

New Aviation Week came in, and it has stories about the 787 and its battery.  So far it looks like the battery is the culprit, not the charger or 787 wiring.  Boeing is floating the idea of adding a fireproof battery box to contain the fire when the battery decides to burn up.  Silence from FAA and airlines.  I cannot imagine either of them being happy about that solution.  Boeing is wringing its hands over the idea of changing back to ordinary batteries, say nickel cadmium or nickel metal hydride.  The paperwork burden looks awful, it would add a couple of hundred pounds to the empty weight and Boeing is still hoping some magic discovery about the battery will yield a non flammable lithium battery.   The Japanese battery maker has not been heard from. 
   Personally, I think Boeing ought to bite the bullet and get rid of the lithium and get the plane flying again.  They can appeal to their Congressmen to expedite the paperwork thru FAA.  It will cost, but having $200 million airliners piling up around the factory costs too.
