IMHO, the Wavelength Selectable black front projector screen demonstrated by Sony at the 2004 Society for Information Display conference in Seattle will make anyone reconsider a LCOS, LCD, or PDP purchase. The InFocus DLP based projectors would do quite well matched with the Sony screen.
Basically it makes placing a projector and screen in the solarium a viable option.
Brillian's LCOS engine looked nice at the show, but this screen got me more excited.
In the Dutch auction style, what happens if a company bids the first high bid and takes all shares?
In this scenario, the share price would be determined by the first bidder, the highest bidder.
Are there restrictions in place to keep a company from doing this? Is it a bad business idea, b/c the voting rights are lower than the original owners?
I work in the general aviation market. Whenever you put LCDs in the cockpit, you have to consider sunlight and take the appropriate steps to enhance the LCD and backlight.
For LCD viewing in sunlight conditions, you want to have a brightness of at least 150 foot Lamberts. Generally the CCFTs will degrade over time, so derate that by 50 foot Lamberts. You are looking at a spec of 200 foot Lamberts in your backlight brightness. Not common in off the shelf laptops.
The contrast ratio needs to be greater than 200:1. The higher the better.
You also want Anti Reflective coating applied to the front of the LCD. This causes reflections in the screen to be diffused and blurry, instead of sharp and clear.
Actually you want the LCDs to flicker, but not at a rate noticeable to your eyes.
If you turn the LEDs on and off for short periods of time, then you save power.
The LCD applications that I work with we usually have a microcontroller do Pulse Width Modulation of a gate driving a set of LEDs that are current limited with resistors.
The current limit resistors set your max brightness level, and the PWM controller allows for software controlled dimming.
If the LEDs are mulitcolored, then you could also control the ammount of Blue, Green, or Red with software and mix your own colors.
I just tried to put my Linksys G card in, and when I booted, the DVD player told me that there was no card present. Apparently, the DVD player that I got was one that needed the firmware upgrade (stoopid me should have checked that first), and since I applied the upgrade, the video is flying. Bringing up that first mpeg and the quality that it was in made this purchase worth every dime. (But I still wish there was DVD-R/RW support...)
I think that this comment could be interpreted to say that the 802.11G card is supported.
Awesome advice. I am still runing my Sony 17" 17se2 monitor from '96. It was 1300 retail back in the day, but it has NEVER been anything but spectacular.
My speakers are steel encased, triangular shaped self powered Advent 570s that totally rock, and I can use them for DJing parties.
Usually I will pick up the latest M'board, and stick a low-end CPU, with enought memory to get me going, then upgrade as the price/performance point changes.
I'm running a Nvidia TNT and am going to go to the store right now to get a better card.
Er? I don't see many free neutrons running around in a normal environment, unless you're working near a nuclear reactor. That 11-minute half-life tends to make them go away - they're a negligible component of cosmic rays. Do you mean alphas? Alpha particle strikes on electronics are a known thing - that's why ECC is around.
I don't mean alpha particles. I mean neutrons. One source of the neutrons is generated from cosmic ray interaction with our atmosphere.
I do know the industry uses Neutron Flux as a unit of measurement:
The level of measurable Neutron Flux fluctuates with changes in altitude and latitude. Also solar flares can cause a 10 fold increase in measureable flux levels.
For soft error rates, the neutron particles are the most important.
I don't have a doctorate on this subject and cannot claim to be an expert in heavy ions. I would not be able to comment about half life and decay. A nice article by Dr. Eugene Normand is my source.
To quote Intel's own engineers: "As semiconductor technology advancing to 90nm feature sizes, radiation induced soft errors have become a major reliability concern." C.Dai Presentation
I wonder how many software errors will be caused by neutrons hitting the processor and upseting logic gates? I have not seen any test results from Los Alamos for 90nm processors using EIA JESD 57, (1996) JEDEC Standard - Test procedures for the measurement of Single Event effects in Semiconductor Devices from Heavy Ion Irradiation. Unfortunately the Radhard server at NASA is down right now so I can't check the server for the latest test results.
Some people think Failures in Time (FIT) rates will get better at 90nm than 130nm. Some think the opposite.
Xilinx and Actel are arguing over it.
Caches are epecially vulnerable. In a critical software application, this is unacceptable, and sometimes the cache needs to be disabled altogether.
One method of addressing this is built in checksumming on the cache, and triple redundancy on certain registers like program counter, etc...
This does induce a performance hit.
If there is a problem, it should be documented by the pilots and the airlines, the FAA should get involved, and electronic engineers should be paid to conduct an investigation.
what if lightning strikes a plane in the exact wrong place and it manages to cook the onboard computers?
RTCA document DO-160D specifies the environmental testing that all aircraft electronics are required to pass in order to be certified for installation on a plane. All of the electronics that are critical to flying the plane have to be tested and shown to pass.
Section 22.0 and 23.0 are specifically to address lightning. This includes direct lightning strikes.
Audi cars will be completely drive-by-wire cars with no mechanical backups, as will planes soon.
The Audi and Honeywell systems are interesting because they provide no mechanical backups for controlling braking/steering/engine control. They still leave the controls up to the driver/pilot.
IMHO the situational awareness of the computer will be far greater than the situational awareness of a pilot, when monitoring GPS inputs, terrain databases, and TDMA based auctioning of airspace/freeway.
A technically intelligent reviewer would have linked these together:
1) Size...we were still struck by the size of the device... . It looks and feels like an Game Boy Advance on a diet, and although it's large by modern mobile phone standards, it fits comfortably in an average trouser pocket and is light enough to carry around comfortably.
2) Backlight N-Gage, by comparison, has superb resolution, a consistently bright display and excellent colour contrast.
3) Graphics Processing ...we do wonder why Nokia chose not to put something like ATI's mobile 3D graphics chip into the N-Gage... The inclusion of a dedicated 3D chip would also have eliminated the framerate problems which plagued a number of the games we tested on the unit...
4) Battery Life ...and I'd be a bit worried about the battery life too - my current phone lasts for days without a charge, but this one seems to run down pretty fast when you're playing games on it."
Those are retty critical design tradeoffs in embedded systems. Also the headache symptoms in the review may be due to the LCD clock and the backlight pulse width modulation frequency being out of sync. This is known to cause eye strain in optical designs.
Many other people have posted the same thing, but here is a real world example of when Quick and Dirty solutions are required:
LIMA, Peru (Reuters) - Lacking the proper instruments, a Peruvian doctor at a state hospital in the Andean highlands used a drill and pliers to perform brain surgery on a man who had been injured in a fight, the doctor said on Thursday.
"We have no (neurosurgical) instruments at the hospital.... He was dying, so I had no choice but to run to a hardware store to buy a drill and use the pliers that I fix my car with, of course after sterilizing them," Cesar Venero told Reuters in a telephone interview.
The patient, Centeno Quispe, 47, had arrived at the hospital in Andahuaylas, 240 miles southeast of Lima, after being hit in the head with a metal object in a street fight, Venero said.
"I drilled holes in his skull in a circle, leaving spaces of 5 millimeters, took out the bone with the pliers and removed the clots that were putting pressure on his brain," he said.
Andahuaylas is one of the poorest regions of Peru, a country in which more than half its 27 million people live below the poverty line.
Venero, who earns $430 a month, said he had used tools from a hardware store on five previous occasions but for less serious operations.
Quispe was making a good recovery in a hospital in Peru's capital, Lima. "
Much of the information you "wish we had" is described in educational research papers.
For example in 2000 Marc Waldman, Aviel Rubin, and Lorrie Cranor published a paper describing Publius:
Publius: A robust, tamper-evident, censorship-resistant web publishing system (2000)
Marc Waldman, Aviel Rubin, Lorrie Cranor
Proc. 9th USENIX Security Symposium
As you can see by the link, many others have written how-to's for anonymizing network communications. The papers are archived in CiteSeer.
Perhaps one has already mentioned this previously, but why not mirror future high bandwidth submitted items or pages on a newly created Yahoo Group?
This submission is a perfect example of why and when to do this.
As far as the how? Simple, create a group with archives open to the public, then attach the files in the files section. After you are done archiving the link, then submit the story.
There is a filesize limit on the group accounts, but anything below that would work. Seven or so days later, delete the group.
From a pure monetary perspective, why would a business find contracting valuable? Money savings.
In Redmond, WA, and elsewhere I assume, your business license fee is calculated on full time employee hours. Contractors hours are counted as hours towards the contracting company, not Microsoft.
If you have a business with 15,000 employees you are paying over $1,000,000 US to license your business in Redmond, WA:
(1) Base fee: $12.50 per full-time employee (or $0.0065 per employee hour worked).
15,000 x 12.5 = 188,000 (2) Surcharge: $55.00 per full-time employee (or $0.0286 per employee hour worked).
15,000 x 55 = 825,000
188,000 + 825,000 = 1,010,000.
The ABA estimates 10,000 temporary workers were in the lawsuit. That works out to be $675,000 in savings from the business license. Estimate an additional $9,000 per temp in benefits savings, and bring the total to $90MIL. Obviously the savings is in the benefits portion of that.

You can still use them to get a couple of different services, but cellphone apps today have the same capability.
Now their focus is VoiceXML applications.

I have a paper for your list. The paper topic is fault tolerant computer systems and is referenced heavily in Aerospace/NASA/Military reseach...
The Byzantine Generals Problem (1982) Leslie Lamport, Robert Shostak, Marshall Pease Advances in Ultra-Dependable Distributed Systems, N. Suri, C. J. Walter, and M. M. Hugue (Eds.), IEEE Computer Society Press
It basically points out that in fault tolerant systems, you need a minimum of 3 sources to determine if one source is bad.
This new bar would offer the benefits of o2, botox, and 3G networks in one place.
Add a little pot smoke in there to combat the nasea and it should make that trip to Rodeo Dr. that much easier.
