Last year a program had to respond within 30 seconds. If your algorithm is fast enough to respond easily within a time limit then performance is not much of an issue. Performance does matter if you and your program have to make an effort to respond within the time limit.
When the pipe narrows, the water molecules rub together and the pressure increases. I guarantee that when cars rub together the pressure increases.
The advantage of computer-controlled cars is they could chat and agree to do things such as alter spacing and balance between lanes, and cars would not jump ahead in the line to the detriment of everyone behind them.
The traffic sensors can fail so the traffic light designers may make the light change every few minutes to prevent trapping vehicles. Or the traffic sensors are overly sensitive. Or the traffic designers put in some light changes to keep that light synchronized with the rest of the traffic flow. Or you simply did not see the car which hit the sensor, turned right on red, and vanished from sight before you came along and got the red light.
I'd prefer a PRT system like Taxi2000. Walk less than 4 blocks, push the button to call a vehicle, while waiting tap the touchscreen with my destination, get in the car. The vehicle goes automatically to the stop nearest my destination. The vehicles are for 3-4 riders and do not stop to pick up/drop off more riders.
That is called a "pressure wave" or "shock wave". One slowdown ripples backwards in the flow. There can be positive feedback to make things wors, such as 3 lanes to 2 lanes; the funnel effect causes one wave slowing traffic in the 2 lanes but the lane which ends is empty because everyone merged...a car hops out of line, runs up to the front of the line, jumps back in where the lane ends, causes another wave...
Actually, what I do now is show the status of my applications. The software equivalent of blinking lights, shown as status screens on CRTs.
I tend to make applications with status variables mapped in shared memory. Then a monitor program attaches to the shared memory in read-only mode and displays the current state. Several clients have seen such displays while I was testing and demanded that they be permanently installed next to other status consoles.
An extension is using status fields where the programs record codes for various decisions. Then a status program can display phrases such as "Pump 3 not started because Valve 5 set to Tank 2, which is empty". Those values are displayed elsewhere on the screen, but programs can point out why things are not proceeding.
Or, with the DIPC patch for Linux, you can share the shared memory between the machines in a DIPC cluster. So one machine can collect data and any others in the cluster can view it...or all can update it. Particularly useful if the data collection program must run with system privileges, as the display programs do not need special privileges.
The mainframes which I started with had panels of blinking lights because they showed the actual bits in the hardware registers. Watching the Program Counter let you see how much it was switching between routines or programs, except when you switched from RUN to STEP and wasted a lot of real time stepping one instruction at a time.
Now perhaps that glowing panel is decorative, or perhaps it is an LCD display for Linux to display messages upon. The photo page did not seem to have a spec link.
I'd like to suggest that the last couple of batches of Slashboxes be listed in a "New Boxes" or "New Options" section of the user configuration page. It's getting hard to find what has been added sot he configuration can be properly tuned.
NASA has been involved with some technologies. Too bad the NASA COSMIC software repository has been in limbo for years.

There have been three amateur plume reports. Two were would-have-missed-it-if-I-blinked and the third was the following ( enhanced Lunar Prospector plume):
hello all of you. I have a homemade 6" refractor, and 50 mi east of LA out here in the mountains is where i travelled last night to watch the moon show. I brought along my WATEC WAT-902H CCD camera and I must of took over 200 exposures into my laptop during the 2 minute interval. i've been painstakingly going thru the images and i think i may have found a winner. please look at it and tell me what you think. I do not have any fancy enhancment software so if anyone out there can enhance this please let me know via email. thanks, John M. image url: http://24.5.74.115/astro/scans/imag0134.jpg
It is far too late to avoid contaminating the Moon with Earth bacteria. Things leak off the Earth all the time, and every major thunderstorm currently wandering across the globe is accelerating air, water, and bacteria into the upper atmosphere. Some of that stuff gets blown off and pushed by the solar wind across the Solar system. Of course it gets dried up in the process, but some bacteria and viruses survives that. There's even argument as to whether Earth's first life form originally appeared on Earth or Mars.

Well, at least RHAT did involve an e-trading company in the IPO so they helped drive the network technologies which helped create them.
I just wish I had made my name more visible. As it was, the one RPM of my stuff got taken out after RH 4.2...

You can have skill and abilities without a degree. Or with one. All the entries should be in a single competition, as they were last year.
OK, then do it digitally. Feed the audio to machines which digitize the sound. Then just select which sound server you want to play.
Here, try a Java Traffic Light Simulator.

Feel free to improve LinCity traffic...

I wonder why my email to their team didn't get there.
I wonder if there was a business plan for creating the business plan...

I've gotten a few spams in Chinese. Romance languages I can handle, but I have no idea what "Remove" looks like in Chinese.
Here's one paper on the origin of oil. Basically, that hydrocarbons deposits are not biological, and biological traces are from bacteria.

Actually, yes, the book does mention what the monolith does to the primates.
