I had a professor that had a great way of teaching that got completely around the clicker problem. He simply incentivized you to read the section we were about to learn by quizzing you on it first individually and then in groups of 5-6 before he taught it. The quizzes were worth a tiny percentage of your grade, but allows him to know where to focus his teaching on during lecture time so we know the content inside and out by the time he tests us for meaningful marks. By far the best prof I had during university, you actually learned the course content. It allowed the content to be difficult but not overwhelming. He even had all the statistics that showed exactly how well his methods worked compared to more traditional lecture formats. And since the lectures were actually adjusted to make sure we knew all the key points, they were actually worth attending as he wouldn't just teach the textbook (though for most of his courses the notes were the textbook, which was an optional purchase at cost if you didn't want to download and print them yourself).

This extension is one of the few reasons I'm still using Firefox, the browser has gotten pretty terrible of late. This was a feature that Opera lost during the move to WebKit as well.

Yeah, this is why I was confused by this report. Lithium-ion cells have to get VERY hot in order to vent, and even then, they have multiple safety systems that attempt to prevent failures that could start a fire. If cargo compartments were getting hot enough to set cells off there would be complaints about many other things melting first. I would be surprised if the cargo compartments even reach 60 Celsius (140 F) which are within the operating bounds of lithium-ion cells (though at seriously reduced performance).

The only reason I could possibly see a higher incidence of cell explosion when on aircraft is if the cell was in a non-pressurized compartment such that the sealed cell expanded in such a way that an internal short was caused in the cell causing a fire. Even that would require the failure of at least one safety feature on the cell.

Combustion

I've been calling for a device that can be best described as the combination of these two Asus products since before the iPad was announced. I want a tablet with a touchscreen but also with a Wacom digitizer built in. If they made it so that you can hook it up like an extra screen to a different computer, but also had the ability to run like a normal tablet PC, I would buy one in an instant.

I'm failing to see how this is news. Many courses of mine do not allow laptops. I even had classes that required you to sit in the front row if you wanted to use your laptop. For me I have had classes that I only attended because of the rare occasion something useful came up and entertained myself with my laptop most of the time instead, otherwise all my notes are pen and paper.

I guess I'll respond to this since I am a battery scientist (well research assistant, close enough) and handle lithium almost daily. The safety of these will probably greatly depend on whether the electrolyte they use is flammable. Lithium by itself isn't going to cause much of a fire, it would mostly react with nitrogen in the air in a completely unexciting manner. If the electrolyte is flammable then there could be significant safety issues if the lithium contacts water. The amount of electrolyte in current Lithium-ion cells causes gases to be expelled if it burns and that is what causes explosions. A couple other things I notice are, they don't specify the voltage of the cells, or the current they can discharge at, they may only be usable in low current applications. I also know there are regulations about how much metallic lithium you are allowed to bring onto a plane, which would probably limit their use in most devices if they are viable.
