Programmable Quantum Computer Created 132

An anonymous reader writes "A team at NIST (the National Institute of Standards and Technology) used berylium ions, lasers and electrodes to develop a quantum system that performed 160 randomly chosen routines. Other quantum systems to date have only been able to perform single, prescribed tasks. Other researchers say the system could be scaled up. 'The researchers ran each program 900 times. On average, the quantum computer operated accurately 79 percent of the time, the team reported in their paper.'"

Scientists Say a Dirty Child Is a Healthy Child 331

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

Comment Re:Hmm... Pretty sure I ran into an issue somewher (Score 1) 201

Absolutely correct! I use VMWare images of Win2k Server et al and we had to use NewSID to avoid problems. Your images have one SID so when you try and run multiple copies, (especially with a Parent/Child DC's) you get problem. For us, it happened about 50% of the time. For some reason, some students could make all kinds of copies of Win2kserver, run them and have no problems.

I run VMWare at a college and we typically have the students run a scenario of Primary and secondary DC's. Unless we used NewSID, we had problems. The weird part was, it was intermittent. Some students would create multiple copies of the same image and had no problems, others would have nothing but grief unless they used NewSID.

Comment I've avoided buying a computer because of Vista (Score 1, Redundant) 332

I've noticed some great deals on computers lately but, with all the grief surrounding Vista, I just could not be bothered to by a new PC or a laptop. I supposed I could have just blown away the OS and reloaded XP, but I honestly just can't be bothered to piss away a day trying to do this. And Linux is not an option because some of the apps I'm using are not available on Linux. I wonder how many people have felt the same way.

Comment Real legislation is finally needed in this area (Score 1) 517

I read a book a little while ago called 'Geekonomics: The Real Cost of Insecure Software' and I have to agree with the author's general sentiments. It's high time that real quality assurance came to software development. Real standards could be set and software would have to comply with those standards. I don't by the argument that this will stifle creativity. If we end up with better products, we will all benefit. Software development tools are now WAY better than anything we had in the past. Now how could the affect Open Source? Well, if Open Source software was proposed by a vendor as a solution, then that vendor would have to be responsible for ensuring that the code would conform to a third party quality assurance criteria. If the QA comes back and the system sucks, someone is going to have to fix it. Then the questions comes, who PAYS to fix Open Source software. Since a lot of Open Source relies on free labor, this could become a problem.

Comment Depreciation costs are total nonsense (Score 2, Insightful) 1137

Whenever, I read these studies, they want to factor in depreciation. Unless you are running a business, DEPRECIATION IS NOT A COST! You bought the vehicle and your money has already been spent. It's gone! You CANNOT expense it a second time. Once the car is bought and paid for, your expenses are gas, maintenance and insurance. The one thing these studies rarely ask is: What is your time worth to you?

Comment Pull your head out of your A$$ (Score 2, Informative) 253

..and look around you when you are walking around. I'm sure many of us have seen people just blindly walk into the road figuring 'well, I have the right of way, car must stop'... Defensive driving is about paying attention and looking ahead. The same applies when you are walking around. If you are walking into traffic without paying attention, it's 'evolution in action'. This sort of safety mechanism is stupid and expensive and really won't do much to save lives. If you get hit by a car at anything over 20kph, you'll likely spend the rest of your life in a wheelchair drooling.

Comment What happens when you get off the main road.... (Score 1) 368

If you live in some of the more sparsely populated parts of Canada/US you know how quickly cellphones signals disappear when you 'get off the main road'. If you don't live near a major city or town, you may be relying on dial-up internet. That makes programming your music gadget problematic. That's what makes services like this great: You can be anywhere and still get great radio. If I was on the road all the time, or lived out in the country, I would definitely subscribe to this.

I agree with you completely. There are not that many old or antique/vintage vehicles on the road.I know what its like to be completely flat broke and keeping my so-called 'clunker' running was the difference between earning a living and being bankrupt and homeless. Now, I spend my spare time restoring an old car and I worry that some enviro-nazis will get elected and insist on trashing so called 'old' vehicles.

Comment Get rid of this Nonsense! (Score 1) 755

Get rid of this nonsense! Last year there was a horrific school bus crash that killed a little girl and severely injured some other passengers. The driver clipped a gravel truck that was parked on the shoulder of the road. I have always believed that had the school bus driver been driving the the daylight, this never would have happened. I hate it now that I'm stumbling around in the dark while waiting for the bus and then going to work. The only 'savings time' that would make sense up here in Canada is between June 20 and September 20. It certainly makes no sense the further south you go. The differences between your longest day and shortest day don't warrant messing with the clocks.
