Comment Re:Why not have a pc / netbook that can do more fo (Score 1) 115

But would you agree that it's just not feasible with current technology to replace the textbook? I mean e-ink displays with color can't be that far off.

Yes and no. I think you make a valid point, and yet the hybrid technology proposed in the article is an important step in the right direction. What I'm resistant to is the argument against moving in the direction of digital textbooks altogether in the absence of a perfect product. Color e-ink certainly sounds like a nice future, but in the meantime I think we need to get products in people's hands that start to turn the battleship. There will be a lot of infrastructure and process required to convert the textbook market into a viable digital system. What are we waiting for?

The panel was the biggest issue by far, but the general 'exuberance' of the desktop environment put people off a bit. It even took me a while to figure out how to get the panel widgets back after they'd disappeared. It just didn't seem to want to do it and was amazingly frustrating. KDE apps like Dolphin, KPPP and others I have nothing by admiration for. Brilliant pieces of software. I used Dragonplayer myself on my Gnome desktop until I moved over to Mplayer (yes, command line. It's a bit old school, but it works so well.) The ideology behind the structure of KDE4 is very well thought through and quite impressive. The follow through leaves a bit to be desired though...

KDE3 was just too busy. To me it was like a manic depressive woman constantly on manic, or watching Bay Watch in fast motion, with everything bouncing around all the time. Personal preference there though. I found it just too distracting, too much going on. It'll be interesting to see how the crowd at KDE sort out this tabs idea. Hopefully the execution will be as good as the planning this time.

Submission + - Digital Archives Threatened By File Corruption (enterprisestorageforum.com)

storagedude writes: The article says massive digital archives are threatened by simple bit errors that can render whole files useless. The article notes that analog pictures and film can degrade and still be usable; why can't the same be true of digital files? The solution proposed by the author: Two headers and error correction code (ECC) in every file.

From the article:

"With all the compression technologies in use, often the loss of a single bit can mean the loss of a whole file. How many times have you opened a digital picture at home only to find that it is unreadable? Back in the 1990s, there were a few RAID companies that ignored errors on read for the broadcast industry. These companies did this because if you are playing a commercial for the Super Bowl, it is better to lose a few bits in replay than to not be able to play the commercial and lose millions in revenue. Very often the few bits that were lost were not even noticed.

"File and data integrity have to change or we will eventually lose all of our long-term archived data. The potential cost to industry and governments around the world — and the threat of the loss of our shared history — mean that we have to do something. Everything is going digital, from medical records to old movies, photos and documents. The current methods may have worked in the past, but they won't work in the future."

Submission + - Central Nervous System for the Earth (edn.com)

bohobourgie writes: EDN reports HPs announcement of CeNSE, an Internet of Things project comprising a network MEMs accelerometers capable of detecting "a 10 femtometer change in the position of its center chip. That’s about 1,000 times more sensitive than accelerometers used in a Wii, an iPhone or an automobile’s airbag system.” Solar power applications are implemented in the announcement as well as strong noise density performance. The data storage requirements are not trivial either: “At a typical data rate, one million sensors running 24 hours a day would require 50 hard disks running in parallel to capture the 20 petabytes of data created in just six months.”

Submission + - Pirates offer Windows 7 on USB sticks

Sam writes: Ars reports: Pirates have been selling Windows 7 on the black market long before the operating system was officially released on October 22, 2009. That said, as far we can tell, it's a first to see Windows 7 being sold illegally on USB drives, the selling point being that they work much faster than DVDs. In China, Netac U208 8GB USB drives preloaded with Windows 7 are being sold for 98 yuan, or about $14.

Submission + - Google Launches Public DNS Resolver (blogspot.com)

AdmiralXyz writes: Google has announced the launch of their free DNS resolution service, called Google Public DNS. According to their blog post, Google Public DNS uses continuous record prefetching to avoid cache misses- hopefully making the service faster- and implements a variety of techniques to block spoofing attempts. They also say that (unlike an increasing number of ISPs), Google Public DNS behaves exactly according to the DNS standard, and will not redirect you to advertising in the event of a failed lookup. Very cool, but of course there are questions about Google's true motivations behind knowing every site you visit...

Comment It all depends ... (Score 1) 735

While full time and salaried I was the only IT personnel on staff and was effectively on call 24 / 7. Fortunately the staff of ~65 only needed me on a rare occasion, which I took non-monetary compensation in the form of vacation hours equal to the time I spent fixing problems during non office hours. It worked for us in that situation.

At my current job I've somehow regressed to hourly full time and do on call in shifts. Here I record the time I spend working while on call after business hours and include it on my time sheet. I either let it be overtime (x1.5) or just leave early on Friday. This works for my current employer.

During a very short lived contract position my employer arranged service contracts with his clients and I got a share of the contracts for the clients I was "on call" for.I guess you could call it a retainer fee.

It's very situation dependent.

I actually did a PhD in physics in an unrelated area. However, one does learn a few things. For example that a PhD is not a license to state that you are right. Appealing to authority is just about as anti-science as you can get.

"You have not published a paper in a peer reviewed journal" is not a valid argument.

Peer reviewing is there to help with weeding out as much BS as possible. However, good insights can come from anyone.

Finally, what you do hone as an Engineering student and a PhD is your BS detector, and that is all that it takes to make a valid contribution. All of these sites are criticizing what others have done. Of course, that is a lot easier than publishing original new work. However, getting proof that something isn't correct is also a worthwhile contribution. One single falsification (go and read your Popper) is all that it takes to invalidate a theory.

Steve McIntyre actually tried to go much further than this. He wanted to review the data and reanalyse it. Had he been allowed to do so, and actually reproduced the results, that would have been as scientific a contribution as I can think of.

Unfortunately, he was refused access to said data.

India Hanging Up On 25 Million Cell Phones 103

jvillain writes "India is about to pull the plug on 25 million cell phones in the name of fighting terrorism and fraud. 'The ban by India's Department of Telecommunications has been unfolding gradually since Oct. 6, 2008, six weeks before the attacks in Mumbai killed 173 people and wounded 308. A memo then directed service providers to cut off cellphone users whose devices didn't have a real IMEI — or unique identity number — in the interests of 'national security.' Since then, the move has picked up steam as a way to circumvent terrorists using black market, unregistered cellphones. The Mumbai attackers kept in touch with each other via cellphones and used GPS to pinpoint their attacks, which started Nov. 26, 2008, and went on for three days. The telecommunications department has issued warnings and deadlines through 2009 but has announced this one is for real, telling operators to block cellphones without valid IMEI numbers. Previously, it warned companies to stop importing them and customers to stop buying them.'"

Google Patent Reveals New Data Center Innovations 82

miller60 writes "'Google is seeking to patent a system that provides precision cooling inside racks of servers, automatically adjusting to temperature changes while reducing the energy required to run chillers.' The cooling design uses an adjustable piping system featuring 'air wands' that provide small amounts of cold air to components within a server tray. The cooling design, which could help Google reduce the power bill for its servers, reinforces Google's focus on data center innovation as a competitive advantage. Check out the patent application and a diagram of the system."

Should You Be Paid For Being On Call? 735

theodp writes "Fortune's Dear Annie takes on the case of poor Dazed and Confused, an independent webmaster who's expected to be on call for his client at all hours of the day and night, but doesn't get paid for being on call, only for the 40 hours a week that he's in the office. Surprisingly, Annie throws cold water on the contractor's dreams of paid OT, citing these pearls of wisdom from an attorney who's apparently never had the 'privilege' of being a techie on call: 'Many companies see the on-call issue as analogous to a fire fighter's job. Most of the time, a fire fighter is off-duty but on call, hanging around the firehouse, cooking, sleeping, or whatever. What that person really gets paid for is the relatively small, but crucial, amount of time he spends walking into a burning building with an ax. A webmaster, likewise, has slow times and busy times.'" What on call policies are you used to working with and how should it work in an ideal world?

Life and Work On the LHC At CERN 81

An anonymous reader sends in a CNet Crave interview with a working physicist at CERN. The interview is full of detail about what it's like to work in this geek paradise (if a bit dumbed-down for an audience assumed not very technical). Dr. Paul Jackson, a particle physicist working on the LHC's Atlas experiment, says there's no chance of black holes wiping us out, and that the time travel speculation is bunkum. He is 100% convinced that they will find the Higgs boson. The scientists there favor Macs, while computers in the control room are Linux-based. "What would happen if you were standing in front of the beam? You would die. It would be a pretty spectacular death, and you wouldn't know a lot about it. ... It would be the equivalent of having 87kg of TNT dumped into your body."
