Comment As a computer/technology teacher (Score 2) 268

I like to have my lab set up with tables put together in the middle of the room with computers around that wall. This allows space for lessons and planning away from the keyboards. Students like to move tables around when they are working in groups. Computers around the wall gives me a view of all the screens allowing me to keep students on task.

33 children injured total is not a huge number. I think more children are injured by electrical outlets, knives, stoves, etc around the house each day. Parents need to watch their kids. The child in the summary would have had a lot less trouble if they had taken the kid to the doctor immediately; rather then waiting a few days. If the child is in pain they need to get the kid checked out asap. That being said there could be a warning in the box stating that swallowed magnets warrant a trip to the doctor, but I don't see why this a news fro nerd or really something that matters to most.

Comment As the resident nerd teacher at my school (Score 1) 415

I tend to form close relationships to the nerdy students in the school, and I tend to have more in common with them then the other teachers I work with. I also politely inform each student that tries to friend me on Facebook that I won't friend them until graduation, since I use my Facebook for personal rather then profession purposes. Once they graduate I have no problem friending them if they approach me again.

Submission + - How Well Will Linux Handle Future Multicores? (mit.edu)

eldavojohn writes: Multicore (think tens or hundreds of cores) will come at a price for current operating systems. A team at MIT found that as they approached 48 cores their operating system slowed down. After activating more and more cores in their simulation, a sort of memory leak occurred whereby data had to remain in memory as long as a core might need it in its calculations. But the good news is that in their paper (PDF), they showed that for at least several years Linux should be able to keep up with chip enhancements in the multicore realm. To handle multiple cores, Linux keeps a counter of which cores are working on the data. As a core starts to work on a piece of data, Linux increments the number. When the core is done, Linux decrements the number. As the core count approached 48, the amount of actual work decreased and Linux spent more time managing counters. But the team found that 'Slightly rewriting the Linux code so that each core kept a local count, which was only occasionally synchronized with those of the other cores, greatly improved the system's overall performance.' The researchers caution that as the number of cores skyrockets, operating systems will have to be completely redesigned to handle managing these cores and SMP. After reviewing the paper, one researcher is confident Linux will remain viable for five to eight years without need for a major redesign.

If you live in the north-east Verizon is the only carrier to provide "good" coverage. I have used AT&T and T-Mobile. I only pay $73/month for my Verizon Droid (450 min, of which I use maybe 100; 200 text; Unlimited Data). This is comparable to my iPhone which I paid $86/month but I can actually use my Droid as a phone and Actually have the internet in my pocket, vs. the iPhone which was a bad phone when it got service and only really had the internet available in cities or near wifi.

What advances in Cellphones? A little faster, a little smaller, a camera, maybe a 'full' keyboard for texting.

I'd argue that cellphones have really started to make the just from mobile phone to personal mobile computer. Every year it becomes easier to use them to truely intergrate the online world into our personal life. They are becoming the Tricorder or Hitchhikers Guide. The next few years the features of the high end phone will become common for all users. Data will be a standard addition to every cell phone plan.

I think these generally compare with the cars you listed. In general our cars are quite a bit heavier then you'd think. The weight is in the frame of the car and has metal to move the force of accidents around the passenger compartment, and to adsorb the force of impacts by crumpling. All of the plastic and fiberglass is in the exterior panels which have never been structural. Thanks to technology gained in recent years, people walk away from pretty impressive collisions in modern cars. The numbers show us that our cars are many times safer today then they were back in the day.

.7 deaths per 1000 vehicles in 1979 to .2 deaths per 1000 vehicles in 2001 http://www.scienceservingsociety.com/p/161.pdf
Over the last 10 years the number of collisions has stated fairly constant between .15 and .18 per 100 vehicles. http://www-fars.nhtsa.dot.gov/Main/index.aspx

They are better for doing work on yourself. I am nut sure that I believe that your classics can do better on gas-mileage versus a high-gas-mileage hybrid. The reason that they get such gas-mileage is that they are build with lighter materials then modern cars. This means that they do not stand up to impacts the same way that a modern car does. You are essentially driving a car that will seriously maim or kill you in a serious accident. I am not saying that classic cars are bad, I seriously want a late model Corvair, but I have no illusions that it is a "safe" car; but it is no more dangerous then anything else on the road at that time. Enjoy your classics, they are beautiful cars that are fun to work on and drive; but don't believe that they are better then modern cars as a daily driver.

>Here's a simple thought experiment: If Evolution is false, what created swine flu? The only other possible explanation is that God is a dick, and I don't believe that. Actually if you are referring to the biblical God, how can you not believe that he is an enormous dick. What do you call and entity that destroys everything on earth, sans one couple of each species? What do you call an entity that turns a woman into a pillar of salt for looking back at the city where she lived as it is being destroyed? What do you call an entity that punishes a rapist by requiring that he pay the father to marry the victim. I call him God.

Submission + - EMI removes DRM from parts of catalog

An anonymous reader writes: Ars Technica is reporting that EMI will announce on Monday that it will be freeing much of its catalog from the shackles of DRM. The Wall Street Journal, citing "people familiar with the matter," reports (sub. required) that Apple CEO Steve Jobs will be present at the announcement in London and that the music will be sold through the iTunes Store and possibly other online outlets. n early February rumblings were heard that EMI was thinking about ditching DRM, but EMI was unable to entice the likes of Apple, Microsoft, and others. As it turned out, EMI wanted a considerable advance payment to offset what it perceived as a "risk": selling DRM-free music online. EMI's position was simple: if they sell music without DRM, then users will find trading it that much easier.
