Would these supercritical thingies bring the US up to par? Seems that the power efficiency would be comparable, based on what you mentioned above. "Ultra-supercritical plants have a thermal efficiency of 44% HHV, which is a 35% improvement over traditional plants."
"Itâ(TM)s anticipated that temperatures and pressures can be increased further, and that a thermal efficiency of 46% (HHV) can be achieved in the next several years. These would be referred to as Advanced Ultra-supercritical plants."
46% would probably mean 41% improvement over traditional plants? (46/44*1.35)
*sigh* and by "intermediates" I meant "intermediates of reaction w/ chlorine" according to the wikipedia section on byproducts.
Oh, and wikipedia also said. "a 4-year study of possible effects of triclosan (0.3%) in toothpaste on thyroid hormone function found no effect of triclosan on thyroid hormone concentration in sera of adult human subjects"
You'd think that would suggest no significant bioaccumulation or eventually the endocrine disruption effects would show up.
Yeah, well, my car was averaging 38 (gasoline), not max. On highway, I could do a bit better. 40. And that was despite driving 75+mph I checked out http://www.fuelly.com/car/bmw/520d/2012
and it looks like the 520d owners aren't doing much better. But they might drive a bit more aggressively than I do.
US uses the 1/128th of an oz - similar to other imperial measurements where it is powers of two for easy division. (16 tablespoons in a cup, 4 cups in a quart, 4 quarts in a gallon). The brits use 1/160th of an oz for some odd historical reason.
So, when I told someone my car was averaging 38mpg between fillups, he thought it was pretty bad, since for him that would be equiv to 31.6mpg in the US. When I read a car report from Britain and I read that the car is getting 45mpg, I get excited at first, before I realise that's about what my car gets.
Ah. I do 8 finger typing (6 fingers, both thumbs) in landscape mode on a Galaxy Note (might be easier in the next one which is supposed to be a tiny bit larger). Qwerty of course.
On a 7" tablet I can do slightly cramped 10 finger, and of course normal typing on a full tablet.
Anything smaller than the Note though, yeah, forget it.
Eh. I had the same problem with rapid-key press games (button mashers).
And walking involves a large range of motion. Pressing the exact same, or close to it, key with your pinky (which dvorak worsens with its greater pinky use), is a subtle small motion that we aren't really evolved to do for 8 hours a day.
As for the mouse. That sucks. Perhaps you should try what I do and use the other hand. Of course, I switched to alternating before the damage got too bad. You might no longer be able to do it.
BTW, I don't know if you have an Android phone or not, but there are alternate keyboard layouts, there is probably a dvorak one. The Hacker's Keyboard is a nice qwerty keyboard that is great on tablets or whatever, if you are connecting to like a tmux session from your android device.
Doesn't really work like that in my experience. Repetitive Stress Injury has as the key variable, repetitive. If I'm playing a first person shooter and my use of the keyboard is basically limited to pressing two or 3 keys over and over, the exact same motion, I'm twitching the exact same muscles, moving my tendons the exact same distance, keeping my wrist in the exact same position. It is murder on my hands, and I notice.
I had RSI in the past and changing my habits (cutting back on gaming, changing the mouse thing) made a huge difference. Ten years ago I was afraid I wouldn't be able to continue my job. These days, I'll type for hours at a stretch without even a twinge.
See my other more extensive post as to why considering pairs is pretty flawed. If you feel it has some validity for your tping speed, feel free to consider it. In the other post I examine the distribution by finger and why Dvorak makes no sense for me personally, with my typing style and speed.
The point is that for any significant body of text (i.e. typing over a period of a few paragraphs or even hours of typing) that the overall work done by each hand will average out. At that point you need to consider letter distribution. It hardly matters that you typed 2 or 3 letters with one hand in a few split seconds if you then type 2 or 3 letters with the other hand. Over the course of hours, letter frequency is the key parameter.
It is pretty meaningless to consider letter pairs, when you spend only a fraction of a second on any given letter. Given I can type 86 words per minute on complex bodies of text (and much faster on text like this) I can type an average of 7 letters in a single second. Requiring alternating every other letter is just silly...
Ok, as promised, the last analysis. Stress per finger, each layout. Keep in mind this is the keys I reflexively push, per finger. Other people might vary. For example, I always use my index finger for c. Others might use their middle, but I find reaching down with the middle finger, tiring on the keyboard...
Now, you might look at this distribution and say that it shows a move even distribution for Dvorak. But I see it pretty differently. Pinkies are the fingers I get the most tired with. Dvorak makes me use my pinkies almost 19% of the time. Ring fingers are the ones that have the most strength for me, and the ones I'm the most comfortable typing with. Qwerty uses them almost 45% of the time versus 34% for Dvorak. Now, you might find that an advantage personally, but I'm going to avoid it. Not to mention of course the fact that with almost all the keyboards in the world using Qwerty, there's already a cost to switching.

Again not a huge difference, but Dvorak stays on the home row a bit more. The difference isn't huge though.
I'm going to do another one where I break it down by letters typed by each finger.
So, I ran an adapted version of the script from my other post on a few texts... $ freq2.pl ~/Docs/bwulf10.txt QWERTY left hand set of qwertasdfgzxcv uses 58.2541631304434% of letters, by frequency Dvorak right hand set of fgcrldhtnsxbmwvz uses 59.8493774873726% of letters, by frequency

So, overall, Dvorak uses right hand slightly more than Qwerty uses the left hand. However, I do feel moving the fingers off the home row is important for stretching them and avoiding RSI, so that should be considered as well. I'll do a version that considers how much each layout stays on the home row in a moment.
So, I did a quick frequency chart perl script. For dvorak the right hand uses 57.7% of the letters For qwerty the left hand uses 57.6% of the letters So, I'd really call it a wash on alternating hands. However I'd still call moving the fingers around, beneficial.

As I said to Dixie_Flatline, one of the big arguments for Dvorak is keeping frequent letters on the home row. I find RSI is more about repeatedly making very similar hand movements. I've not had RSI symptoms typing on a Qwerty keyboard. Even for hours at a time. I *have* had RSI problems w/ video games where I repeatedly press keys that are very close to each other. I've also had it when repeatedly left clicking with the mouse or making the same small wrist motions, which is why I alternate mouse hands these days.
I'm inclined to think that Dvorak would be mean more RSI precisely for the reason they advocate it - keeping common keys on the same row, preventing your fingers from moving about much.
My typing speed is 86wpm on the Astronaut text on typingtest.com so I'm not inclined to try learning Dvorak since 1) It would slow me down on other people's keyboards 2) I fear potential RSI 3) My speed is fast enough for my purposes w/ Qwerty
As for alternating hands more in Dvorak... Difficult to say. The analysis using aspell by the other commenter seems flawed to me since it treats b as a left hand key which seems unlikely for most people, and ignores letter frequency. out of etoain in etoainshrdlu, 3 are left hand, 3 are right hand in Qwerty.

Er. Sorry, bring *coal* up to par.

You'd think that would suggest no significant bioaccumulation or eventually the endocrine disruption effects would show up.
Welp, I couldn't find too much on wikipedia on accumulation of triclosan itself, just the intermediates,
but random-ass site w/ no citation for the fact says that.
"Triclosan is lipophilic, which means it can bioaccumulate in your fat for long, periods of time"
http://articles.mercola.com/sites/articles/archive/2011/07/27/how-washing-your-hands-and-germophobia-can-damage-your-brain.aspx
It also linked to articles mentioning presence in milk/blood/urine, but those articles didn't mention bioaccumulation.
Ugh. That's what I get for trying to do math on just waking up.
mg, not g. :)
Sooo, 2 tubes of toothpaste.
That's still a hell of a lot of toothpaste
Given I normally don't swallow any.
Hm. But let's say there's a kid out there who gets into the toothpaste.
If a small kid ate an entire tube, it'd be time to call poison control and induce vomiting from the sounds of it.
Huh. So an adult male would have to eat like a kilogram of the stuff?
One toothpaste label reports 0.3% triclosan.
That's 0.5g of triclosan per tube.
So to hurt myself I'd have to *eat* almost 2000 tubes of toothpaste?
Agreed. Even case sensitivity and whitespace isn't a problem.
Just hash it in lowercase w/ whitespace stripped.
I would hope most banks already do this.

Yeah, well, my car was averaging 38 (gasoline), not max. On highway, I could do a bit better. 40. And that was despite driving 75+mph
I checked out
http://www.fuelly.com/car/bmw/520d/2012
and it looks like the 520d owners aren't doing much better.
But they might drive a bit more aggressively than I do.
(all measurements above in US gallons)
Anyway, 52mpg is indeed pretty damn good. Looks like it has regenerative breaking which helps on that front a lot.
Diesel though. In the US diesel is more expensive than gasoline.
http://thegreencarco.com/blog/news/diesel-more-expensive-gasoline/
Popularity of gasoline probably also explains why it is abbreviated in the US and not so much in europe.
Ugh. I mean. Oz is 1/128th of a gallon or 128 oz in a gallon
Other way around from how I said it.
The fuel economy one is particularly problematic for UK vs US measurement.
http://en.wikipedia.org/wiki/Gallon#Comparison_of_historic_gallons
US uses the 1/128th of an oz - similar to other imperial measurements where it is powers of two for easy division.
(16 tablespoons in a cup, 4 cups in a quart, 4 quarts in a gallon).
The brits use 1/160th of an oz for some odd historical reason.
So, when I told someone my car was averaging 38mpg between fillups, he thought it was pretty bad, since for him that would be equiv to 31.6mpg in the US.
When I read a car report from Britain and I read that the car is getting 45mpg, I get excited at first, before I realise that's about what my car gets.
He said he had a bug that was causing him to lose like one bit in seven.
He's pretty confident he can fix it and improve reliability.
So, the inconsistency, he claims, is not so much a weakness of the method or due to any security at all in the device, but more his hardware.
Ah. I do 8 finger typing (6 fingers, both thumbs) in landscape mode on a Galaxy Note (might be easier in the next one which is supposed to be a tiny bit larger). Qwerty of course.
On a 7" tablet I can do slightly cramped 10 finger, and of course normal typing on a full tablet.
Anything smaller than the Note though, yeah, forget it.
Eh. I had the same problem with rapid-key press games (button mashers).

You'd think we'dve improved techniques in the last 150 years.

The Hacker's Keyboard is a nice qwerty keyboard that is great on tablets or whatever, if you are connecting to like a tmux session from your android device.
Another reason you might have problems w/ your pinkies in Dvorak is:
http://hardware.slashdot.org/comments.pl?sid=2970657&cid=40615879
I'm inclined to think the other things you changed were the majority of it. Not to mention slowing down to learn a new layout.
Nonetheless, I'm relieved you got things fixed. RSI was pretty scary for me. I hadn't thought about just how helpless I'd be, and unable to do my job.
Doesn't really work like that in my experience.
Repetitive Stress Injury has as the key variable, repetitive.
If I'm playing a first person shooter and my use of the keyboard is basically limited to pressing two or 3 keys over and over, the exact same motion, I'm twitching the exact same muscles, moving my tendons the exact same distance, keeping my wrist in the exact same position.

As I said to Dixie_Flatline, one of the big arguments for Dvorak is keeping frequent letters on the home row.
I find RSI is more about repeatedly making very similar hand movements. I've not had RSI symptoms typing on a Qwerty keyboard. Even for hours at a time. I *have* had RSI problems w/ video games where I repeatedly press keys that are very close to each other. I've also had it when repeatedly left clicking with the mouse or making the same small wrist motions, which is why I alternate mouse hands these days.
I'm inclined to think that Dvorak would be mean more RSI precisely for the reason they advocate it - keeping common keys on the same row, preventing your fingers from moving about much.
My typing speed is 86wpm on the Astronaut text on typingtest.com so I'm not inclined to try learning Dvorak since 1) It would slow me down on other people's keyboards 2) I fear potential RSI 3) My speed is fast enough for my purposes w/ Qwerty
As for alternating hands more in Dvorak... Difficult to say. The analysis using aspell by the other commenter seems flawed to me since it treats b as a left hand key which seems unlikely for most people, and ignores letter frequency.
out of etoain in etoainshrdlu, 3 are left hand, 3 are right hand in Qwerty.
