Daul layer DVD+R DL:

a much cheaper step on the way to BD with 1/3 the capacity instead of 1/5. Have had 50% coasters with these. Very few dual layer burners actually support them & none of the first dual layer burners support them. The "RW" on the packaging does not mean rewritable.

Micron:

finally had to face the music & admit it can't pay off Steve Appletree's executive mansion & 23,500 Idaho employees simultaneously. 3,525 Idaho workers must go. Another state fails to create jobs outside Calif*.

The end of the world:

The end of the world is Nov 5. Election complete, no need for more bailouts & no more money. Banks foreclose on everyone because their property is worth 10% of their loans. Paulson & Bernanke catch the last flight to antarctica. McCain & Ubacka take the escape pods to Canadia. Congress hides in the WV bunker. Dubya wanders around looking for a beer. Dogs & cats live together. Dead rise from the grave. 30 years of darkness, earthquakes, volcanoes.

Infinite universes:

Used to think there were infinite universes & our sensations were in a gaussian curve of many related universes. That's depressing because it means no matter what U do & who U meet, there's always another version of U who succeeded or failed & the people change every week, so nothing matters. A more likely story is there is only 1 universe & our sensations R in a gaussian curve of many beings in the same universe. Dying simply causes U to have sensations from another being in another part of the same universe.

Fl*rida timelapses:

Comca$t increased its upload bandwidth to 1.5Mbit. Finished cutting all the timelapse movies from Fl*rida & now U get the reap the rewards with fl*rida timelapses in HD. This is the timelapse footage we collected on the Fl*rida farm, on the mighty EOS 5D.

Well, got a recurrent network for cyclic feedback trained to where it was pretty close to the PID equation in the training algorithm. Unfortunately, it was completely erratic when run on the airframe. Training the recurrent network is definitely hit or miss. Most of the time, the evolution gets stuck & U need to restart it.

Now on to algorithm 2, comparing a sequence of steps from each mutation to a sequence of PID equation steps. The 2.4Ghz dual opteron from 4 years ago is coming out much faster than the 2.6Ghz Athlon X2's & core duos of today. Maybe the current stagnation in clockspeed means more assembly language jobs.

There's a limit to how accurate these networks can be & a definite dependancy on the structure of the network.

The 4Ah maxamps.com we got for $94 in 2006 R now $150. 60% inflation. Even the 3.3Ah cheapbatterypacks.com ones R $130, easily 100% what they charged last year. Interest rates just fell to 1.5% so it's time to buy.

Like any return of the neurons, it's not going well. The mission is to model a PID equation in a recurrent neural network. Once all our PID equations R modelled in neural networks & flying, the next step is to have the networks evolve from the starting PID equations in flight.

Training the recurrent neural network to act like a PID equation has 2 genetic routes.

1) Feed 1 random input into a PID equation & solve once using a random neural network. Throw the network out if the single solution deteriorates. The previous output of the PID equation is fed into the neural network & the integral in the PID equation is carried over to each step. This gives the neural result which would have resulted if it was predicting correctly & it was carrying an integral. Very slow & less likely to give a good integral part.

2) Feed a sequence of random inputs into a PID equation & compare with a sequence of solutions from a random neural network. Reset the PID integral before every sequence. Throw the network out if the solution sequence deteriorates. Very very very very slow & more likely to work.

It's taking populations of about 1000000 & around 4000 generations for genetic algorithm #1 to arrive at reasonable error rates. Nothing to do but procrastinate & have some more Fl*rida.

Fixed some more photos 4 U. Had to relearn how to survive in the dumpy apartment, what to do when heroineclock goes off, how to use the dumpy light switches, where to sit, where the shower head is. Waking up the first time after a long trip, U have to wait a while to figure out where U R. Especially confusing because it looks exactly like Fl*rida outside the dumpy window. U actually still think you're where U were. Who knows how a neural machine would relearn its long term memory....Continue Reading

For your last transmission from Fl*rida, U get some star trails over the farm. Time to start heading back to silicon valley.

The answer is yes. There R lots & lots & lots of alligators in Fl*rida. On the Hillsborough river, they're as numerous as the mosquitos. 240 million year old scale technology triumphs over newer fur & skin technology.

Make no mistake, Tampon is the home of New York stock brokers after they make millions on mortgage bailouts. They all have New York accents & the Tampon flag is the Lexus SUV. They've created a virtual New York complete with traffic jams, virtual Manhattan island, lots of bridges, & New York driving techniques. It had a population boom in the 80's & is a few mortgage bailouts from another, so the alligators have fresh meat to look forward to....Continue Reading

Small enough to fit in a roadster, smarter than Dubya, & coming to a management office near U.

So crammed $280 of gas consumption into 1 week so now we have only 1 beach & some timelapse movies left. Need some fair weather clouds. Star movies over a few minutes R impossible because we don't have the lens heater to defeat condensation.

Combine a 24000 bits/sec uplink with a pile of broken web 2.0 scripts from The Goog & U get hours & hours & hours of waiting & retrying. As expected, the defective Ubunt bunt xlib & gcc have been falling over constantly. Without your own technology, there's nothing but horses down here. A bit crazy that anyone could actually make a living down here & consider the green monster of fields & moss their home. Never found a job down here. Just went to school & left to jobs Francisco like everyone else. It's a green postcard.

Got perfectly clear weather at night & such a dark sky it felt like
falling into space. Also, the quest to make a field look like it's worth $700 billion resumes with crazy lighting. It's the same crazy lighting we remembered from 8 years ago.

Finally made it to the Fl*rida compound. Spent a lot of your taxes on the mortgage for it. Cell phone internet access is still the measly 48000 bits/sec down & 24000 bits/sec up of GSM way way way way way out here. It's so humid & hot, doubt VicaCopter would have worked. Her voltage regulators, & batteries would have surely exploded.

Fixed wings won't be doing takeoff & landing rolls here. U can't beat the star fields between the permanent clouds. Not...enough...bandwidth...for...photo....captions .

until October. Unfortunately, couldn't qualify her for an aerial photography mission in time to order the first $200 of gear & we have a battery shortage, so there will be no Fl*rida shots.

Got the ground based autopilot tested in the gusty wind. Unfortunately the days of daylight are over. Still flying just like the Gumstix autopilot....Continue Reading

The 2 tiny thumbnails from Aviation Weekly are the only record we have of the F-117 demolition. Everyone wants the most advanced aerospace technology, but we've got to pay off some mortgages.

Following up on HP, NVidia dropped 360 engineers into the dead pool today. Who's next?

Whew, & U thought your 20 year old 72Mhz transmitter was slow.

Speaking of bloodbaths, USB serial adaptors R going up in price like multi family housing. They're becoming novelties for the rich & famous, subsidized by giant government banking complexes. So could only afford 1 and sacrificed one of our 5V hacks.

The enclosed ground station is a disaster on the grass. Raising XBee & friends on merely a sheet of paper boosts the signal quality to 100%. Signal quality in flight was perfect.

Snagged a spot on flight in dead calm air with manual position control. She really needs tight attitude control, otherwise she gets into nasty circling oscillations.

Looks like OQO did an HP.

http://dbmoore.blogspot.com/2008/09/changing-guard.html

People wanted a touch sensitive display instead of a keyboard. A real winner would be a pocket computer strapped to a transmitter.

Technology crashes are defined as 2 consecutive pops in 2 days. Time to start learning how to write teen barbie lottery web 3.0 scripts.

Still don't think people get as excited by pure software as they used to & as much as investors think they do. The Green Tech appeal may not be the greenness at all but the interaction of software & physics. Physical software.

Maybe it dates back to when programming meant having an electrical equivalent to every command. We humans naturally equate physical programming with value. Manipulating abstractions & interfaces doesn't feel as valuable as manipulating energy & mass. Maybe that's why humans aren't going crazy over standards based programming.

Since we can't find a ground station enclosure, U get more EOS excitement instead.

HP's (latest) 25,000 mass layoff should get the message across. Jobs which don't have to be done near corporate headquarters can be done in Bangalore, and corporate headquarters are always in Calif*.. We predicted EDS in Dallas would be eliminated & it was. Well, half of them can still move to Bangalore.

Had a successful radio test. 8 hours without a failure.

Time to tabulate the radio settings that work & the radio settings that don't.

Good radio settings:
---------------------------------------
Ground:
115200 bps
40ms beacon interval


Copter:
57600 bps
3.3V - 5V comparator



Failed radio settings:
---------------------------------------
Ground:
115200 bps
21ms beacon interval

Copter:
115200 bps
3.3 - 5V comparator
Copter UART failed.
---------------------------------------
Ground:
57600 bps
40ms beacon interval
Ground XBee failed.

Copter:
57600 bps
3.3 - 5V comparator

Well, 57600 is a draconian reduction in bandwidth but it seems to be required to keep the PIC UART from locking up. The ground station seems to handle 115200. The 3.3V - 5V comparator did nothing. What a disappointment.

The XBee lockup has moved from the UART into the transceiver. Now feels like too many collisions at just the right time may lock it up. Maybe it was designed to wait for ACKs after broadcasting instead of having packets pushed into it.

Even though no-one uses all that mesh networking, their investors keep forcing it on us...Continue Reading
