traffic lights were fed the position and speed of all vehicles on nearby roads and programmed to calculate how to phase colour changes in order to optimise traffic flow
THAT sounds good.
If a set of lights told drivers when they were about to change, “drivers [could] adapt their speed accordingly to avoid useless accelerations or react faster on green,
a. Isn’t that what the yellow light is for? To tell people when it is about to turn red?
b. We don’t necessarily want people jumping the green light. That’s a safety issue. It’s bad enough people try to beat the red by zooming thru the yellow. (I’ve been guilty of it - hasn’t everyone?) But what if people were also beating the green? (It’s about to be green, so no need to brake…)
For this to work, vehicles must transmit data to the computer system that controls a city’s lights.
And how long after we are transmitting that data to the city’s system will it be before law enforcement figures out they can use that to determine who is running a red light? Speeding? Tailgating? Shouldn’t do those things anyway, you say. Well, how about being investigated because you’ve supposedly been stopping at questionable street corners? Cruising low income neighborhoods? What if you were just handing out information about the local homeless shelter?
I have misgivings enough about putting my car on a traffic network or relying on one for information. (I probably don’t have too much to worry about, since I live in the sticks and see less than 20 other cars on my way to work.) But I have even bigger misgivings about what other people could do with that information.

On Thursday, WalMart begins selling the Everex Green gPC TC2502, a $198, low-powered, Linux-based PC that’s designed primarily for running Web 2.0 apps.
When users first fire up their gPC, they’ll get a Mac-like desktop with a series of program icons “docked” across the bottom. The icons are really bookmarks to popular and useful Web 2.0 services from Google and other vendors….
I’ve got a headache already just thinking about the home users who will be totally confused by this. Such as…
Why can’t I install all the software and games I had on my old PC? (That was Windows. This is Linux.)
Where are my files? (They’re not on the hard drive…they’re on the internet.)
How come none of this stuff works? (You didn’t dial in to the internet first.)
Why can’t I use Outlook Express? That’s what I’ve always used for email… (This isn’t a Microsoft PC.)
But my (digital camera, scanner, printer, mp3 player, etc.) doesn’t have drivers for Linux?!? (They only make them for PC and Mac. For instance, Kodak Easyshare….)

Can’t wait to try this (I think I copied it from Lifehacker.com):
Save YouTube videos for any device with vConvert
Web site vConvert.net grabs videos from YouTube and converts them to compatible formats for your iPod/iPhone, mobile phone, PSP, and more. What’s more, if you only want the audio from a video, vConvert can convert just the audio to an MP3. We’ve seen desktop apps that promise the same conversions (and one other web site), but if you don’t want to install an application to handle this simple transcode, vConvert is a very good and simple alternative. Just give it a YouTube URL, select what you want to convert it for, then click Convert and Download. After a minute or two of processing, you should see a download link for the video.
I can’t tell you how disappointed I was when I realized I couldn’t SAVE a youtube video to put on my pda and watch later…

http://www.theregister.co.uk/2007/09/20/it_risk/
Gartner group vice-president Richard Hunter also author of " IT Risk: Turning Business Threats into Competitive Advantage" , defines IT risk as " anything that poses a risk to either the availability, access, accuracy or agility of a business" . He ranks availability as most important. " Dollars spent on availability are dollars well spent," he said.
One thing that jumps out at me is " agility" . I’ve found that as our company grows, we have been losing agility. As we incorporate more checks and balances and testing into our application development process, we lose the ability to pop out new applications or new features as-needed. As we standardize on certain software and hardware, we lose the willingness to incorporate one-off items where the business processes call for it - at least without a lot of red tape and justification. Even processes themselves, such as processes surrounding purchasing and procurement, can hamper agility.
While I agree that agility is important for a business, I am struggling to see how businesses that are trying to please auditors and improve processes can also maintain agility. Hunter himself seems to recognize this, too: " IT risk is related to IT value. It would be short-sighted not to recognise either value or risk," Hunter explained. There are risks associated with agility. When we roll out an application with little testing, it may fail. We allow a department to use a consumer digital camera, but our Helpdesk struggles to offer assistance because they aren’t familiar with the product, and we find there is a hidden cost - it isn’t as durable as the models we usually buy. A new vendor doesn’t deliver quickly enough, and our project is delayed. We spend weeks taking calls from laptop users before we determine that the new laptop battery fits too snugly and doesn’t always charge. We lose agility when things go throught the layers of testing necessary to prevent most of these failures, but we lower our risks.
This article goes on to explain that IT managers need to better be able to explain the risks to executives. But again, it is couched in an explanation of what happens when a server fails, which is a function of availability. Measures which ensure availability are fine, but I think most businesses are seeing the value of availability, access, and accuracy. It is agility which has taken a beating. The article references a loss of agility due to government regulation, but offers no suggestion that this should be considered, and no advice on how to regain agility.
So I’ll offer my advice: build transparency and trust into your IT department, instead of processes and red tape. Give someone personal responsibility for the project, and ensure that they know they will receive the calls if it fails, and they’re likely to do a much better job of preventing it from failing. A bunch of red tape, lab testing, and good vendor references doesn’t guarantee that a new barcode scanner will work. When it fails, who feels personally responsible for getting it fixed? Nobody. " I checked the vendor’s references " , says one guy. " It tested fine in the test lab " , says another. No one person is personally invested in the project, so why are they going jump up and dig in when it fails? But when someone has a cradle-to-grave relationship with a project, they feel personally responsible when it fails, and come running to the rescue. Give techs the ability to reject layers of testing and red tape when they can explain why they aren’t necessary, and authorization to utilize a complete test lab when they are, and my guess is that there will be just as much testing, but even better results.

I thought you might like to check out this chart that traces the evolution of Apple product design from 1976 to 2007.
To me, it shows that Apple was always remembering that the cosmetics of the product were important. While they weren’t always on target, you can’t hit the target if you don’t take a shot. Most computer companies barely take a shot at cosmetic concerns. While you do still have to have a technically capable product, when all things are equal, the attractive product wins. Two things are in Apple’s favor there. (1) A large number of people will only use their PC for email, web, music, and pictures. That makes them “equal” as far as those people are concerned. (2) Increasingly, the other capabilites (office software, games, etc.) are evolving for macs and linux, too. So, you’re getting equality for people who need those. (This whole conversation, of course, ignores the potential security flaws/benefits of the products. Those exist on a different plane than what the typical consumer will be concerned with.)
I think “my” first computer was the Apple IIe, but I’d have to ask Alex. (It was his computer.) I remember it had a program that I think was called “Notecard” or something, that I really liked because you could create an “index card file” of your recipes, or your music collection, or your book collection, etc. If I sound like I was easily impressed, remember that it was my first computer. My only other experience was the frustrating experience of trying to use the computers at public school where you had 20 minutes twice a year to follow whatever instructions they gave you without truly understanding (you OR the teacher) what you were doing. (It was the 80’s.) Our IIe also ran off of TWO floppy drives (one internal, one external), and the external drive was beat to the point where it had to be on it’s side to run. This was also the first time I got thumb blisters from playing Tetris…which I am currently re-living by playing Tetris on my Zire72.

From the department of the really obvious: Comparison Shopping Saves You Money The OFT (some UK business thing) estimates that by searching more effectively, shoppers could save £150m to £240m each year. The report also suggests that shoppers are hindered by “unexpected additional charges which are sometimes added in the latter stages of a purchase.”
Well, DUH! This isn’t just the case online, either. Comparison shopping when shopping in the real world saves lots of people money, while others who do not do so pay more. And unexpected additional charges happen all the time. (Can I tell you how many times Radio shack, and even Kmart, have offered to sell me an extended warranty on a $40 electronic? Heck - it was only $40! why would I want to pay $10 fo rthe warranty and then another $10 to ship it to be fixed? I’ll just buy a new one (probably a different brand) if it breaks once the manufacturer warranty is up!

Did you know you can Massage away dead pixels? “Nonconforming or stuck pixels can be a nuisance on an otherwise functional laptop LCD. The pixels usually remain green or red without lighting up properly with the other pixels on the display. Unfortunately, manufacturers will not replace an LCD for just one or two stuck pixels; in fact, some require as many as 10 to 18 dead pixels before they’ll take action. There is a solution, though. Take a soft material, like a felt cloth, and gently rub in a circular motion around the stuck pixel. Performing this trick will usually get the pixel to light up properly. Once you find the right location and pressure to illuminate the pixel, hold your finger there for up to two minutes, and voila, no more stuck pixel. “This is a new one on me. And since eldest was just complaining that Gameboy has a dead pixel, I think I’m going to try it out. However, I wouldn’t go willy-nilly suggesting it to just anyone, and these screens can be easily ruined by too much poking and prodding.

Digging Holes in the Sand can be fatal - who knew?
I don’t know what to make of this story. Saying people shouldn’t dig holes at the beach is practically sacriledge. The danger of collapsing sand holes is compared (and the numbers are pretty close) to shark attacks. That means that both are very, very unlikely. (You have a greater chance of being struck by lightning or winning the lottery.) We don’t say that people shouldn’t swim in the ocean at all because there are sharks. I appreciate that people should know there IS a danger. I wholeheartedly agree with the suggestion that children shouldn’t play in sand holes while unsupervised. (Children shouldn’t do pretty much anything completely unsupervised, IMHO.) But they didn’t do a percentage to show how many hole-digging events go without incident. That would be probably be 99.99%. Children have a greater chance of so many more things being harmful…and of missing out on so many joys because of the fear of such rare dangers. I, for one, will not be discouraging the dreams, ambitions, (and busy work) involved in “digging a hole to China”. Nope, you’re not going to convince me to give that up.
In the words of Jimmy Buffett:
Well I’m a tidal pool explorer
From the days of my misspent youth
I believe that down on the beach
Where the seagulls preach
Is where the Chinese buried the truth
So I dig in the sand with my misguided hands
And if I dig deep enough
Hell I just might dig it up
Talkin’ ‘bout treasure
Talkin’ ‘bout pleasure
Talkin’ ‘bout love

An insightful, yet short, read on why WI-FI IS NOT A HEALTH HAZARD any more than a baby monitor. To summarize:
“…the same spectrum as is used for wi-fi is commonly used for baby monitors…the transmitter is that unit you put by baby’s cot, mere inches from his precious little head… How much of that EMR is absorbed by Jimmy’s brain? None? Yes, none. That’s why you don’t need line of sight between Jimmy’s transmitter and your receiver. He’s transparent to the transmission.”

http://www.theregister.co.uk/2007/04/23/vista_program_naming_oddness/
"This is a little bit silly: just name the installer something else, and Vista lets it through," Chess said. He added that although the feature is imperfect and inconvenient, it’s "better than nothing".
First of all, it’s more than "a bit silly". It’s just stupid. Microsoft says "Windows Vista heuristically detects installation programs". They are obviously using the dictionary meaning, not the common anti-virus software understood meaning of "it checks out the file to see what it does before passing it on". That’s like answering the door with a blindfold on, asking who is there, and then letting them in just because they do NOT say "I’m a really bad man".
Secondly, it is NOT "better than nothing". Because:
- Users will assume that if a file passes this test, it is safe to run. And (especially now that the flaw is known) that won’t be the case.
- It does NOT stop viruses. How many viruses use a filename of "install.exe" or "setup.exe"?
- Users who are supposed to be locked down administratively will still be able to install programs as long as they know how to change a filename. (Chances are, if they’re downloading junk to install on their work computer, they’re savvy enough to know how to change a filename.)
