How Predictable Is Evolution?

kcdoodle Re:Breaking News! (209 comments)

The position of a single Nitrogen atom in a jar is RANDOM.

However, the properties of a mole of Nitrogen atoms in a jar has extremely PREDICTABLE properties.

So it is not inconceivable that a LARGE number of organisms undergoing RANDOM changes may have PREDICTABLE traits at the end of a long period. Mutations that cause DEATH will be quickly weeded out of the population, for one thing. Mutations that do not support survival would go away after a short time as well.

Diversity would occur from DIFFERENT mutations that INCREASE survival chances, maybe there would be a lot of these, maybe there are only a few. This is where the real question lies.

FWD.us Wants More H-1B Visas, But 50% Go To Offshore Firms

kcdoodle Replace Congress with H-1Bs (325 comments)

Lets issue another 535 H-1B visas, take the first 535 people off of the streets in New Delhi and replace congress with them.

I bet they would come to every session, special investigation, ad-hoc committee and all have perfect attendance. They would probably do a MUCH BETTER job, since there would be little in-fighting, and they would not be indebted to some controlling political group.

Just a thought...

Flies That Do Calculus With Their Wings

kcdoodle KCDoodle (107 comments)

Math is my favorite subject.

The nerve cells immediately after the rods and cones in your eyes (and most other animal kingdom eyes) also perform calculus. Edge detection is done BEFORE visual stimuli makes it to your brain. The image and the edges reach your CPU at the same time. This lets you know where things start and where they end. It is a great asset when hunting chasing and running away.

However, it can get confused. This is the reason zebras have stripes and run in herds. With a large number of edges, the predator can become confused of where one zebra ends and the next zebra begins.

I did not learn this stuff in Biology class, I learned it in Robot Vision class.

Why a Cure For Cancer Is So Elusive

kcdoodle What about whales? (366 comments)

This limitation of definitely getting cancer due to not being able to beat the odds is a bad assumption at best.

At worst, it is just a way to grab headlines and get my eyes looking at advertisements on the reporter's page.

See, this same "unable to beat the odds" applies to large animals as well. The bigger an animal, the more cells, the more cells, the more chance that one of them dividing causes an irreversible cancer. Extrapolating to bigger and bigger animals, large whales should all die of cancer before they get large.

But they don't die before they get large. Some other mechanism cleans up cells that become cancerous and the same would/could apply to long lifespans.

Don't worry, if you are going to live forever, you will probably die in a car wreck sometime in your sixth century.

Ball Lightning Caused By Magnetic Hallucinations

kcdoodle Yum Yum. Magnetic Hallucinations... (269 comments)

I was fifteen when lightning stuck about 15 feet away from me.

I saw the air get bright blue, and then I was getting up off of the ground. I never heard the thunder, I felt it. The shock wave literally knocked me on my ass.

Afterward, I had three separate "epileptic episodes" where I was convinced I "SAW GOD". However, now I know that all the synapses in body brain were firing all at the same time, making me feel and think EVERYTHING at once. (((If this is death, then bring it on!)))

But alas, I know that it was just an electro-chemical response to the shock to my system. Reality can be quite a let-down when you analyze things from a scientific standpoint.

Japanese Guts Are Made For Sushi

kcdoodle Re:Many asians can't digest milk (309 comments)

Most mammals have a weaning process where the children normally lose the ability to digest milk. It is part of the transition away from being dependent on parents.

However, humans have affected their own evolution by habit and by necessity.

When the vast expanse of North America was being settled by Europeans (sorry Native Americans), many brought cattle and dairy animals to help settle this continent. During hard times, being able to digest milk as an adult was a significant advantage.

It has been estimated that 60% of "Old World" populations cannot properly digest milk,cheese,cream,etc.. Meanwhile, about 80% of "New World" population can effectively digest lactose products.



Remember, 94.3% of all statistics are "made up" on the spot.

I'd prefer to allocate my work hours ...

kcdoodle My Schedule (287 comments)

In at 8 AM, lunch usually at my desk.

Gone at 3 PM, like clockwork, maybe stay later once or twice a month.

Occasionally work an hour or two from home, usually once or twice a week.

NOTE: Hours working != Actual work accomplished.

My company knows the above inequality and leaves me alone, since I am the most productive worker here. More productive than those who put in 50 hours a week, and we are all salaried employees.

Method To Repair Damaged Adult Nerves Discovered

kcdoodle Re:Excellent (128 comments)

Sorry -- I screwed up! It is Dr. Yehoash Raphael. His Email is a shortened version (which I will not disclose here.) I am not sure which name is his firstname and which is his lastname. And yes Dr. Geoffrey Manley is correct.

Method To Repair Damaged Adult Nerves Discovered

kcdoodle Re:Excellent (128 comments)

This might work for nerve deafness.

However, if it is tinnitus (ringing of the ears) you are concerned with, you should check out the work of Dr. Raphael Yoesh at the University of Michigan.

Also read some of the papers written by Geoffery A Manley on the subject.

It seems that birds can regrow the hairs (cilia) in the inner ear, but mammals cannot.

Now if only I could get the hair growing out of my ears to grow in my inner ear, I would be okay. (What?) (What?)

Bing Gains 10% Marketshare

kcdoodle Re:Bing is an ad server. (514 comments)

I thought heterodyning was the process of adding the sound wave to the radio wave. I guess it also means adding one radio wave to another. (Thanks.)

When searching "simultaneous radio transmission" in SCIRUS, I do get answers about destructive wave interference. Some suggested solutions have the receiver controlling the senders, effectively multiplexing their transmissions.

There are some other interesting articles about unintentional hetrodyning of two bluetooth signals causing RF outside of the FCC allowed bandwidths. Interesting stuff.

Bing Gains 10% Marketshare

kcdoodle Bing is an ad server. (514 comments)

Well, then again so is Google.

When I want a scientific answer, not a bunch of ads. I go to SCIRUS.

http://www.scirus.com/srsapp

Try any search engine to find out why a third walkie talkie gets feedback when two walkie talkie's "talk" keys are pressed. EVERY site will try to sell you walkie talkies. SCIRUS has the answer. (But it is so scientific I cannot figure out what the answer means.)

I bet it has something to do with destructive interference in the electromagnetic waves, and synchronizing the two walkie talkies would allow the third to hear both voices.(?) Maybe?

3D Fingerprinting — Touchless, More Accurate, and Faster

kcdoodle in the database with all the "bad people" (103 comments)

OK, if you have EVER been printed, then you are in the database.

But that data is subdivided into many categories. There are arsonists, murders, kidnappers, organized crime members and many other sections of the database.

This is simply for faster searching. If you have a latent print at an arson scene, it would be faster to search the arsonists section FIRST, then if you do not get a match, only then do you bother searching the rest of the database.

If every search searched the entire database, all seaches would slow to a crawl and the queue to do a search would be unbearable.

3D Fingerprinting — Touchless, More Accurate, and Faster

kcdoodle Re:fingerprinting (103 comments)

The system you used had no human being screening the results, and what you experienced was "similar fingerprints" and probably not exact matches.

For crimes at least, no person has ever been convicted on the testimony of an AFIS computer.

AFIS returns "possible matches" with in a list of most similar matches to least similar. Then a latent fingerprint examiner (a real live person) determine which print (if any) is the real match.

Also, when you watch CSI and the prints are flashing on one side of the screen while the other side of the screen displays the unknown print, is total bollocks. Fingerprints are reduced to numerical representations and THAT DATA is compared to obtain the list.

BTW, I helped create AFIS.

SSL Still Mostly Misunderstood, Even By the Pros

kcdoodle Quote (292 comments)

This is not my quote, and I do not remember where I read it.

"Using SSL to transfer information from server to server is analogous to using armored cars to transfer bags of money from one park bench to another."

Archiving Digital Artwork For Museum Purchase?

kcdoodle Half life (266 comments)

Data on a DVD/CD doesn't all crap out at once. In normal usage, scratches cause some data loss. However for long term storage significant loss would happen when the plastic reflective surface itself degrades. Still, when properly stored, a DVD/CD should last 30 years. To increase the odds of your data lasting, and to spend the least amount of cash, simply make multiple copies of your most precious data. That way, hopefully, each DVD/CD will retain SOME data and it can all be pieced back together from the multiple copies. The more precious the data, the more copies you should make. I think 5 copies stored in a climate controlled safe should last at least 100 years, if not, longer.

Company Offers Customizable Web Spidering

kcdoodle It's the bandwidth (46 comments)

It is really easy to make a web crawler in Java. (Look at java.net.http or maybe java.awt.net.http) I made a decent one by myself in about a week. Okay, so my web crawler only does TEXT/HTML. No images, no Active X, no video. From experience, an average web page is about 10Kbytes. Now, anyone's specific application will probably be looking for key words, or else you are just re-creating Google. A key word data crawl would return a LOT less information, but would still require a lot of bandwidth and processing power to do the work. So bandwidth and processing time is what they are selling -- the place where this company's services would be most useful.

Using a House's Concrete Foundation To Cool a PC

kcdoodle Re:This is not a concern (465 comments)

Wrong.

The houses in my neighborhood were built around 1980.

All have copper pipes in the slab.

All the houses are developing leaks IN THE SLAB and have to be completely re-plumbed through the attic. My house was re-plumbed about 5 years ago. Next door, they had it done last summer, only after extensive water damage.

Copper pipes in concrete slabs = bad idea.

It may or may not be electrolysis, but something IS damaging ALL the piping in ALL the houses in my neighborhood.

US Switch To DTV Countdown Begins

kcdoodle Drinking Game (293 comments)

In cities with a lot of TV stations -- everyone bring an old analog TV to the party. Each TV gets tuned to a different station. As each station blinks out, everyone slams a drink. By midnight, all channels should be gone. By midnight, everyone should be snockered.

Keeping a PC Personal At School?

kcdoodle Think Sideways. (695 comments)

Switch to Ubuntu. Create a guest account and let them use that.

If you or the people you lend to really need Windows...

Install QEMU, on Ubuntu, it is a nice virtual machine. Take your old Windows CD and install as a FILE in your QEMU Virtual machine.

Keep a couple copies of the Virtual Windows FILE on your hard drive.

When someone wants to borrow your laptop, start up your Virtual Windows Machine in QEMU and lets them play. If the screw up that Windows copy (or if you just don't trust them), delete the FILE and use a new copy of the FILE on your Virtual Machine.

Afraid to Upgrade

kcdoodle kcdoodle writes  |  more than 5 years ago

kcdoodle (754976) writes "Vista finally hosed me.

I had XP/Vista/Kubuntu-HH tri-booting on my laptop until a few days ago, Vista got stuck in an infinite loop of install/reboot for upgrades. After I stopped the shenanigans, Vista needed a re-install.

I decided to not install Vista and switch to an XP/Ubuntu-II dual-boot installation. Now I find that my Wireless card does not work with Ubuntu-II and I have to back-out to Ubuntu-HH or Ubuntu-FF.

After I get this all worked out, I am deeply considering turning off updates (XP and Ubuntu). I am just tired of "fixes" and "upgrades" hosing my system.

Is it safer to let my system update, or should I get a stable system and lock it down forever? I am just afraid that security patches are more likely to hurt me than help me."

SUN Java update offers Open Office

kcdoodle kcdoodle writes  |  more than 6 years ago

kcdoodle (754976) writes "My little Java update icon just notified me there is an update available. Better than that it also said "Click here to download Open Office". I think this will put Open Office on more computers than ever! Microsoft is gotta be sweating bricks right about now, as MSOffice is one of their biggest cash cows. Do you think this will hurt Microsoft at all?"
