Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

the_other_chewey Re:No mention on capacity though (395 comments)

Do you mean a 100kW/hr battery? There is no such thing as a 100kW battery. Idiot.

Neither is there a 100kW/hr battery. Moron.

How English Beat German As the Language of Science

the_other_chewey Re:my rant... (323 comments)

replace Herz, [...] with a more english ideal; cycles-per-second (so much for brevity).

This one is a false near-cognate: The cycles-per-second unit is "Hertz", as in Heinrich, not as in heart.
That still makes it German though...

Texas Health Worker Tests Positive For Ebola

the_other_chewey Re:Everybody Panic! (421 comments)

Do you even know how this case of infection occurred?

I don't. You, however, speculated about contaminated suits which "still have to
be taken on and off, and that's when health workers seem to get infected."
Which really shouldn't happen.

you're the one who says he knows, or rather knows enough to know there was a systemic problem and not one merely attributable to failure to follow established protocols.

Please tell me where I said that.

Huh? Plane flights? Are we still talking about a controlled clinical environment in a big American city?

There are only about a dozen BSL-4 facilities in the US; if you want to establish the principle that patients must be treated in such a facility, you will be moving A LOT of them.

1.) I don't. My video example above was meant as a "look at how the pros do it".

2.) You do expect "A LOT" of Ebola patients in the US?

you seem to think every metro in the US has a world-class biohazard facility and infrastructure, and has plenty to spare on a wild goose chase of isolating minimally-virulent ebola patients, and you can't seem to understand that your fears are based completely on your own speculation and snap judgement. Your conceptualization of this disease, and the means required to contain it, constitute the textbook definition of cargo cult science.

Hm? What part of "don't mix clean and unclean environments" is cargo cult?

Also: I'm not afraid.

Just to clarify: I'm not talking about the Ebola outbreak as such, and arbitrary
patients. I'm talking about this one specific case of an infected health worker in
a proper clinical environment.

Texas Health Worker Tests Positive For Ebola

the_other_chewey Re:Everybody Panic! (421 comments)

So basically you're just anxious, because none of this "seems right" in complete absence of empirical evidence?

Somebody in a modern clinical environment who supposedly knew what they were doing got infected.
That right there is empirical evidence of something not being right.

And in your sample of 10 (or 20, who knows!) one person became ill, because, we dunno, but it sounds fishy.

It doesn't to you? "Well, they have to take off those contaminated suits, and some will get infected while
doing that. Shit happens." really isn't the right approach here.

What recommendations would you make, if you were, say, a public health official? Everyone who develops illness has to be treated in something akin to a BSL-4 facility?

No, but how about "don't mix clean and unclean environments, and follow proper decontamination
procedures while moving between them, and before undressing"?

Have you any idea how many plane flights that would require, just to cite one small aspect of the logistics?

Huh? Plane flights? Are we still talking about a controlled clinical environment in a big American city?

And all this to protect from a disease vector that's completely unsubstantiated in the literature?

Or do you do like Judge Clay Jenkins, and personally go to the family's house in shirt-sleeves and drive them to a new home? Which approach is more appropriate? Which one balances our available resources against the actual concrete threat of the disease? Which one is actually workable?

You're losing me here.

Texas Health Worker Tests Positive For Ebola

the_other_chewey Re:Everybody Panic! (421 comments)

BSL-4 is a standard that only applies to laboratories, the same standards aren't necessarily applied to clinical environments, and in the case of Ebola are major overkill.

I mostly agree, but I'd still expect strict precautions to be taken to prevent the mixing of
clean and contaminated environments. That includes not taking contaminated objects (suits,
gloves, whatever) out of the containment area.

Ebola can't travel through the air, so positive pressure suits aren't appropriate, and they still have to be taken on and off, and that's when health workers seem to get infected.

So WhyTF are they taking off undecontaminated gear?

People who "test positive" for Ebola are not contagious, only people who have symptoms are, and they can only pass the disease through contact with bodily fluids -- this usually implies touch, since hemorrhagic fevers cause people to give off all kinds of gross effluent, but it's just not like a "virus" one gets from casual contact, like, say, rubella.

And still somebody got infected. Somebody who knew they were dealing with an infectious
and lethal disease. This should never have happened. You're not making me feel better about the
competence of those involved.

The fact is, Ebola isn't that contagious -- HIV is more virulent, and these two are nothing compared to the influenza or SARS. It's bad that health workers can get it, but this is still one person, so on a completely epidemiological basis it's really not a big deal. Characterizing a single case as somehow indicative of the safety of these procedures is sensationalism.

Well, yes and no. I'm not really concerned about it "getting out". And while it's obviously not enough
for proper statistics, it's more than enough for concern for the health workers: How many people were
treating this patient? 10-20?

That makes for a 5-10% infection rate amongst people who knew what they were dealing with, in a supposedly
first-rate facility in a highly developed country. And the infection happened despite Ebola "not being that contagious".

Texas Health Worker Tests Positive For Ebola

the_other_chewey Re:Everybody Panic! (421 comments)

well no, I bet a dollar there was a tear in his suit. Simplest explanation is always right.

Be prepared to lose a dollar. The protocol for donning and removing the protective gear is very complex, and very hard to get perfect. When putting the suit on, it's possible to get gaps between the goggles and suit without even knowing it.

Goggles?! - Proper biohazard suits are full-body and pressurized, with a full-head hood and absolutely
no openings in the vicinity of the head. Or any place on the front side of the body for that matter.

And when taking it off, a tiny flap of the contaminated suit brushing against a clean surface is almost impossible to detect.

Eh, again? - There's a multi-step decontamination procedure before taking off the suit.

Taking off a still-contaminated suit would be a major fuckup, and a (potentially) contaminated suit should never
be in an environment where any "un-suited" contact can happen.

Have a look at how this works at the BSL-4 level (skip to about minute 13).

What kind of amateurs are running this place?

How the Ancient Egyptians (Should Have) Built the Pyramids

the_other_chewey Re:Corroborating Hieroglyphics? (202 comments)

It is estimated the Great Pyramid was built in just over twenty years. So say 7500 days - which means placing 320 blocks a day assuming you work 365 days 24 hours a day. Pretty sure the Egyptians would be limited to daylight hours work, so they'd need to cut & move at least 500 blocks a day.

What? No! The limitation to daylight hours meant they had to be faster per stone,
but it didn't suddenly double the amount of stones needed.

A 2.4 million stone pyramid built in 20 years is built at an average rate of 229 stones
per day, completely independent of the length of the work day.

Do Readers Absorb Less On Kindles Than On Paper? Not Necessarily

the_other_chewey Re:No difference (105 comments)

Actually for reading books knowing where you are does help line up the story. (beginning middle or end)

I think that's true. If so, maybe a small progress bar along the top of an e-reader continuously showing where you are in the book could be helpful. I don't know if any e-readers offer such a feature.

Mine does: "Cool Reader" for Android.

It includes tic marks for chapters, a "% completed" number, and even
calculates "time left in chapter" and "time left in book", automatically
calibrated to my reading speed.

It's very unobtrusive and I rarely if ever look at the numbers, but the small,
few-pixel-high progress bar is quite useful.

Solar Plant Sets Birds On Fire As They Fly Overhead

the_other_chewey Re:god dammit. The Numbers (521 comments)

That's 28,000 birds for this current, small, solar installation: 0.4GWh, when the US uses tends of thousands of GWh.

Please don't mix units or make up numbers. A GWh is different from a GW.

This installation has a peak capacity of about 400MW. Total installed peak capacity
in the US (Total net summer capacity) is just a bit over 1000GW.

Interesting note: the growth in capacity over the years shown in this graph is made up nearly
exclusively by renewables and gas, both contributing about half. I hate stacked bar graphs for
obscuring such things, but there's a "download data" option in the top right corner of the graph
so you can look at the raw numbers (they're also in the page source, as a JSON object).

NFL Fights To Save TV Blackout Rule Despite $9 Billion Revenue

the_other_chewey Re:Punishes fans? (216 comments)

its very telling that the NFL needs a *law* to force people to go to games and pay their exhorbitant ticket costs.

It's the law forcing a limiting of the Blackout Rule on the NFL, not
the NFL being forced to use the Blackout Rule by the law.

The NFL doen't even care about people coming to the stadiums:
The teams are allowed to purchase remaining seats to "unlock"
the broadcasting for the price of the league's share of the ticket sales.

So it's the NFL trying to force maximum revenue per game (for the NFL, that is).

NFL Fights To Save TV Blackout Rule Despite $9 Billion Revenue

the_other_chewey Re:Punishes fans? (216 comments)

I don't understand how the rule that prevents airing the matches keeps them on free air channels?

Because the NFL has been forced to allow at least that.

I mean, if NFL wants, they sure as fuck can put on a rule that causes them to be always available for broadcasting? and the other way too for that matter.

Yup, absolutely. That's why Blackout Rule is an NFL rule.

I mean, the "if tickets not sold then no show" as a rule sure sounds like it only makes it harder for them to show the matches if they want.

furthermore, WHAT THE FUCKING KIND OF RULE IS THAT!?!? shouldn't the organizer of the event -any event- get to choose if it can be broadcast or not, since aren't they in control of the copyright of the recording????

They are. And again, it's an NFL rule preventing the broadcasting.
In fact, the NFL had to be forced by law (Public Law 93-107) to at least allow broadcasting
in those instances where a game is sold out 72h in advance.

I do understand your confusion though, the summary does a horrible job at explaining what's going on.

Russia Prepares For Internet War Over Malaysian Jet

the_other_chewey Re:Black box data streaming (503 comments)

My guess is cost. Sending data via satellite is very expensive, and there's a lot of data recorded. As for ground stations, I'm not aware of any plane-to-ground data communications currently in use (other than radio for voice) so that would need a completely new infrastructure built.

ACARS. Already built.
It's rather low-bandwidth though.

trying for a soft touch down with enough rocket fuel ant oxidiser to do a soft touch down is always potentially exciting.

I knew Spacex has done some new and inventive things in propulsion systems.
But oxidising rocket fuel ants? That's just plain weird...
I guess the new facility in Texas will include their own ant farm to keep down cost.

Walter Munk's Astonishing Wave-Tracking Experiment

the_other_chewey Re:Cheap documentary? (55 comments)

Just simple geometry:

Imagine a planet completely covered with water. Now throw in a big stone at one of the poles:
This results in a circular wave expanding from the pole, parallel to the latitudes.
As soon as it crosses the equator, it starts converging again, until it arrives as a peak at the
opposite pole.

Distance from pole to equator: circumference/4.

This works with a stone drop at any other point on the globe as well, I just used poles and
equator because it's easier to imagine. In reality, land masses complicate things a bit of course.

The firing lasted three minutes (a full "mission duty cycle", i.e. a simulated launch) under full power, delivering 3.8MN (or 855,000 lbs.) of thrust. SpaceX have made a video of the test available. The Waco Tribune has a short report about it, with comments by locals."
