Figure 8 on Page 6 of the actual paper shows what they're measuring. They're comparing filter materials by Salt rejection % vs Water permeability measured in L/cm2/day/MPa. That unit incorporates all the energy-efficeny goodness you want in a filter without looking at what pump technology is actually used to provide the energy input. It says that more filtered water (L) per square centimeter of filter (/cm2) per day (/day) per MegaPascal of pressure (/MPa, the energy input) is more good. Assuming any particular pump technology would give you a number for MPa/MJ that you could apply, but it doesn't help you understadn the performance of the filter itself. The figure for improvement vs existing technology they actually give is 2-3 orders of magnitude (100-1000x) so TFS is taking the optimistic side.

The bottom line is that this has a huge potential but is still a ways from practical application.

I'm not sure this would work from the perspective of intentionally including it; but I think it would be an interesting way to "flag" accounts for extra verification. People have different typing styles and your natural timing of entry for a password should be computable from logins over time. If the entry is significantly off it can be a yellow flag to indicate that maybe it isn't you entering the password. Combine that with some other factors (e.g. IP history, user agent strings) and you could perhaps identify accounts that are likely compromised and require an extra verification step.

I don't really have time to work this out and try it, but it'd be very interesting to try.

As a strong supporter of nuclear power I feel this attitude is exactly what makes it so easy to scare up opposition to nuclear power. That article was extremely well written and researched. IMO it presented a fairly balanced view of the existing studies and the overall challenges to new research and regulation. Yes their are concerns about low and protracted doses, and yes the industry has tried to downplay and bury that research. Just like the "green power" industry doesn't want anyone to look at the lifecycle costs on those PV cells and LiPo batteries.

The only way to stop fear mongering and get new power plants is with open and honest research - not making attacks on an article that tries to present the facts.

Do all of those companies actually manufacture their own printers? I thought Dell just re-branded other printers.

Personally, I think this is a great plan. I'm not sure it'll make me buy an HP instead of a computer from system76, but it's definitely a great idea.

That said, my last call to HP tech support for one of my IPS monitors went pretty well once I got past the first 2 levels of non-English-speaking drones, and their actual rep who came out to my house with the replacement display was fantastic. No dumb questions, good communication, and fast replacement service.

This is so true. I'm glad to see the first ask slashdot in a long time where I'll be reading the all the comments at 0 without having any mod points.

That, sir, is the best description of candidates I've read yet.

Gigabit fiber from Verizon? No, I didn't think so.

FWIW, I have Verizon FiOS here, and it's nicer than anything else in the area, but it doesn't hold a candle to what a real high speed connection could look like from Google. Especially since Google owns so much of it's own long-distance backbone, I'm betting their local fiber is going to be wired up pretty well to the rest of the internet tubes.

The difference between a military and a militia is training. Yes, tanks and big guns are extremely easy to fire, but do you know how to work together with others to use those weapons to launch a coordinated assault? Have you practiced and trained until you can work with your squad to clear a building without thinking about it?

This is what has fundamentally changed in the American military since Vietnam, we have fully changed from a loose organization of mostly short-term enlistees, draftees, and officers to a core of professional soldiers who will spend 20+ years in the service, and you know what, it works like a sonofabitch. It raises even the average private in the US army to a level 10, 100 times higher than the members of your militia because they can work together as a team. One on one your militia of hunters and private citizens might do alright, but you don't get any bonus from having them together. If I take a bunch of guys from a military unit the whole is going to be much more effective than if they fought individually.

Training is expensive and time consuming - your militia will never have the time or the money to train the way a regular army can.
