Due to the porous nature of Windows all sorts of malware (virii, adware,keystroke loggers, spam senders) can slide right into your computer from the Internet, from file sharing, from thumb drives, and just plain out of the air. There must be a malware magnet deep inside Windows. If you want to call your computer your own, you have to do something the keep the bad stuff out.
New machines come with something, usually Norton Anti Virus or McAffee Antivirus pre installed and pretending to be free. After some months, the free wears off and the programs beg for money to "keep them selves up-to-date". I used to run Norton Antivirus, but when it begged for money, I took a hit to my credit card but the program still refused to update and shortly just stopped running. Unless kept up to date the program quickly becomes useless. Scumbags from all over the world are constantly writing new malware, and unless updated, the anti virus program won't recognize the new malware when it strikes.
After the Norton failure to update, I started using F-Prot, an old DOS antivirus. So, starting up son's new laptop, I put F-Prot on it and ran it. Surprise, F-Prot only scanned 300 files and declared the computer virus free. That can't be right, even a virgin Windows computer has tens of thousands of files on it. Some googling on F-Prot and "long file names" revealed that trusty old DOS programs , raised on short filenames (8 character name plus three character extension), have trouble with Windows file name that can be of any length and even contain embedded spaces. So much for trusty old DOS antivirus.
Some more googling put me intouch with AVG antivirus. It's free, it updates itself, and it is a real Windows program in which the mouse works. It's 45 Megabytes to download, but broadband makes that happen with ease and grace. It is painstaking, examining file after file.
So if you want to save the maintainance fees of the commercial antivirus programs, try AVG.

The Future of Freedom by Fareed Zakaria
"Illiberal democracy and home and abroad" is the subtitle. Interesting book, published way back in 2003, but I just saw a copy in our modest Abbie Greenleaf public library. The author is an Indian guy, editor at Newsweek magazine, frequent contributor to Wall St Journal op-ed pages, and talking head on the TV Sunday pundits. He is reasonable guy, smart, well read.
He uses language in non standard ways. For instance to Zacharia, democracy means any regime with universal suffrage. Limited suffrage, as we had in this country in the 18th and 19th centuries doesn't count. Regimes that hold elections count, even if the voters don't get much choice, like Eygpt or Hamas controlled Gaza. In normal usage democracy is any regime with a reasonable degree of personal liberty and an elected leadership even if the suffrage is limited to men, or property holding men.

Roadbed for the HO model railroad
The model railroad in the down stairs guest room is progressing. I have the benchwork up, and a layer of 2 inch blue insulating foam down, all around the room. Roadbed comes next. The foam is too soft to take track nails or spikes, and the only commercial roadbed is cork, which isn't much better at taking nails and spikes. Most folk using cork on foam glue all the track down with latex caulk.
This works, but it is unforgiving. If you make a mistake and get a kink in the track (an easy goof to make) repair is hard. The glue is unyielding. More repairable is to fasten the track down with nails. Should you need to realign the track to make changes or get rid of kinks, you just pull up t he nails with long nose pliers and press on.
To nail down track, (or hand lay track) you need a roadbed that takes and holds nails and spikes, like basswood or white pine. Local lumber yards have plenty of pine, but it comes 3/4" thick. Roadbed wants to be 1/4" thick to look right. No problem, I got a band saw off Craig's list. With a new sharp 1/2" blade, and a home made fence, I can resaw pine boards up to six inches wide. The re sawn surfaces are smooth and flat, and with a home brew fence that is truly a right angle and clamped to the table, I can resaw to 1/4" and the stuff looks good. Progress.
So all I have to do, is bandsaw all the curved trackwork out of resawn pine and stick it down with latex caulk. So. Ho, to the stationary store I go, and buy poster board to cover the whole layout. Draw the track plan out full scale on the poster board and cut each piece of road bed out on the band saw. This should keep me out of trouble for weeks.

Computer Cleanup
One thing leads to another. New laptop for youngest son arrived via DHL yesterday. Son was overjoyed, but he is off at college, 7 hours away by road. So son asks if I could start it up, make sure it truly has XP and not ugly Vista. And then could I do some of my Windows XP speedup magic to it?
So, first thing is to port Zone Alarm (free firewall) over from my desktop, so new machine can go on the internet without instant virus infection. According to the trade journals, a new Windows machine will be infected within 10 minutes of going on the net without a firewall. So I gotta burn a CD to move all the goodies off my desktop (Blackbox by name) over to son's new laptop (InlineSkater) It's been a while since backup to CD, so let's kill two birds with one stone. I'll backup and then install Zone Alarm and other goodies from the backup CD.
So, to save time and CD's I always do a bit of disk cleanup before backup so as to avoid wasting CD space on trash. And avoid confusing myself if I ever have to restore from the backup CD. For disk cleanup I still use an ancient piece of freeware/shareware called EZCleaner. The ancient version is free, the programmer, a young kid in Finland, is now charging money for his handiwork. Being a cheap bastard I keep running the freeware version to save a couple a bucks. It's good stuff.
EZCleaner zapped a 100 megabytes of stuff, and I blew away a backup of daughter's laptop and few DVD movies by hand. Freed up four gigabytes of disk. Then I started up my freeware/shareware CD burn program (DeepBurner) . Loaded the last burn script, and Deep burner informed me that I needed a 1 gigabyte CD to fit everything on. Hmm, plumpness has infected my 200 GB hard drive.
Some time later, I managed to fit everything I cared about one two CD's, 0.6 Gigabytes apiece, Saved two new burn scripts, and two freshly burned CD's.
Now that the urge to clean is upon me, I ran my freeware antivirus, F-Prot. It's an old DOS program, it's free, and it even automatically downloads new virus definition files. DOS programs run like lightening compared to Windows programs. I got into F-Prot after Norton Antivirus expired some years ago. I tried to renew Norton, but all that happened was my credit card took a hit, but Norton never worked again. Later I ran into a weirdo bug caused by old dead Norton .dll files left on my disk. Although some googling was able to fix the bug, I have sworn off Norton for the duration.
So, last trick, run Lavasoft Ad-Aware, a freeware anti malware program that specializes in ad programs that slip into your machine via the net. Step one for any malware scan program is to update the malware definition files that drive the program. After clicking on "update malware definitions" the program trundled along and after a decent interval announced that the download failed. So I tried the alternate manual update procedure listed in the help file. No dice.
Some googling revealed that "Ad-Aware SE" was now obsolete and no longer supported, but "Ad-Aware 2007" was now free and supported. A direct attempt to download Ad-Aware 2007 thru the Lavasoft site led into a cul-de-sack that required me to sign up for expensive junkware in order to get the anti-malware software I started out for. Fortunately more googling got me to a site that let me just download "Ad-Aware 2007" and run it.
The Ad-aware run proudly discovered 343 tracking cookies (fairly innocuous items) and I duly zapped them all. Program reminds me of my cat, which proudly brings back every mouse, chipmunk, and bird that she catches to show them to me.
Thus endeth computer cleanup for today.

16% of GNP, but still hospitals claim underfunding
Cspan has Rep Henry Waxman chairing a hearing about adequacy of emergency medical care if we get hit by terrorists again. If Al Quada blew up a subway or something, would the local hospital emergency rooms have enough beds to hold all the casualties?
There were a series of hospital people pleading for more funding to enlarge their emergency rooms. And deploring "funding cuts".
With 16% of GNP being poured into health care, surely we have enough hospital beds within a reasonable ambulance distance of nearly everywhere. And if we don't, why don't we? Where is all that money going? Remember a mere 8% of GNP funded all US health care back in 1980. Doubling that portion should be more than enough.
Then the hearing got steered off to immigration when a Congresscritter opined that illegal aliens (aka undocumented immigrants) were clogging the emergency room beds. And then further off topic when witnesses started testifying in favor of universal health care, aka Uncle pays all doctor's bills.

Barack Obama on Face the Nation
I had a choice between Hillary on Stephanopolis' ABC and Barack on Tim Russert's Meet the Press. I decided to watch Obama, 'cause he promised to be more interesting than Hillary. Russert gave Obama 50 good minutes of TV exposure without every asking Obama to say anything of substance. Russert spend some 15 minutes with Obama rehashing the Jeremiah Wright disaster. This didn't tell me anything I don't know. Jeremiah is not a bullfrog, he is a toad, who has hurt Obama, no one knows how badly, but badly enough.
For the rest of the time Obama was extraordinarily evasive. Lots of smooth, good sounding answers that don't mean anything. For instance Russert asked Obama where he stood on nuclear power. Obama said he was in favor, after safety problems and nuclear waste problems had been properly studied. What does that mean? Would an Obama administration grant construction permits and operating licenses or would they demand lengthy "studies"? Who knows?
Obama still pledges to pull US troops out of Iraq, but he might take 16 months to bring them all home. If a genocidal disaster threatened then he might change his plans, somehow. He promised to support Israel against Iranian nuclear attack by preventing the Iranians from obtaining the bomb. He failed to explain how he planned to work that miracle.
In short, the policies of an Obama administration might be anything.

Words of the Weasel: Alternative Energy
It sounds so virtuous and green that everyone is in favor of it. Alternative energy will replace $120 a barrel oil, clean the air, and reduce acne, cellulite and halitosis. Users of the phrase just let it roll of their tongues and then quickly change the subject.
So what is this wonderful energy source? Well obviously it is not the workhorse conventional fossil fuel sources that keep the lights burning, houses heated, and the traffic moving by air, sea, road, and rail. Could it be nuclear?
Actually nuclear works. Nuclear plants have been running for 50 years and produce 20% of US electricity. Nobody has ever been hurt by a US nuclear power plant. The cost is competitive with $120 a barrel oil. Spent fuel rods have been stored on plant sites for 50 years without a problem.
How about solar? Trouble is solar power only works when the sun is up. Dunno about you, but I want my electrical to work after dark, that's when I truly need my house lights to light.
And wind? Nice stuff, fields of huge windmill blades whirring over the wheat and corn. Cool. What happens when the wind stops blowing? Even mountain top sites have calm days. Of course when the price of bunker C gets high enough we could bring back the sailing ship...
Biofuels? Wood is good, and wood stoves will heat your house. Of course if you go away overnight the stove will go out and then your pipes freeze... Ethanol is going full tilt, due to heavy government subsidies, but it takes nearly as much fossil fuel (tractor fuel, fertilizer, and heat for the still) to make the ethanol as you get back for burning said ethanol. The energy gain from making ethanol is disputed with figures running between 0.5 and 1.5. No one is claiming gain as good as 2.0. Energy gains of less than one mean a loss, making the ethanol consumes more energy than it yields.
Hydrogen fusion? After 60 years of R&D, no one has created a fusion reactor that stays lit for more than a second or two, or that yields more energy than the reactor machinery consumes. There are two promising efforts under way, the multinational $13 billion ITER in France, and the shoestring Bussard Polywell in the US. Neither project has lit a break even fusion reaction yet. Wish them well, but a lot of very smart people have been working on the problem for 60 years without success.
Next time someone says "alternative energy" ask them what they mean.
