I lived in an apartment under a crack cocaine dealer when I got my first 2400bps modem. I recognised the deal being offered then. The deal is the same now, but the free gear is being stopped.

So
It's also why the NE of England had a full dress rehearsal for an Ebola case collapsing in a public place a couple of days ago.
I wonder how long until they go on strike over this?
The unions (RMT, ASLEF) have been pointing out that without drivers, there is going to be no-one to react to suicides (which close tube lines and stations for around a day each time, causing huge disruption, and it happens frequently). The train drivers are also trained to operate the heart attack machines on most trains and platforms, and routinely save the lives of passengers by being present to react.
You're right - there are plans in place for strikes to resist the de-drivering of trains.
Have you any idea what percentage of the UK's GDP might be affected by such a breach in the underground transport system?
I do have an idea that it was really stupid to build in such a place.
I blame the Romans myself for being so inconsiderate as to build a city at a fording point of a major river. If only they'd forded the river up on top of a hill somewhere, London wouldn't have any problems with flooding.
Still, you can avoid it by choosing where to live in the city. My city has a harbour that is inconveniently at sea level, and the harbour often floods in heavy rain or high tides. But my house is 25m above the harbour level and has a site slope of about 2 degrees, so rain water runs away down hill. It's not rocket science.
Many tests for hydrocarbons are cross sensitive, such as a sensor for Propane will detect gasoline, natural gas, butane, etc.
Very true. I've put together and worked gas detection machines for three decades now. Different sensor technologies have different cross sensitivities. It sounds as if your experience is with IR absorption sensors, probably on one wavelength (more wavelengths reduce cross-alkane sensitivity, but increase cost ; single wavelength sensors are fit for purpose for flammability/ explosion risk monitoring, but not for interpretive/ analytical work).
What sensor is used, what is the sample time, what else is it sensitive to, and were there any significant accidents or releases in the area recently?
FTFA ; sorry, the second FA
In the study published online today in Geophysical Research Letters, a journal of the American Geophysical Union, researchers used observations made by the European Space Agencyâ(TM)s Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY)
FTFIWP (From The Fucking Instrument's Web Page, http://www.sciamachy.org/
is a passive remote sensing spectrometer observing backscattered, reflected, transmitted or emitted radiation from the atmosphere and Earth's surface, in the wavelength range between 240 and 2380 nm.
Well, that tells me enough - medium UV to medium IR, plenty of appropriate absorption bands there. If they say "methane" they mean "methane."
If it was from the soil, soil based sampling should have seen this concentration long ago in gas exploration.
Looking for actual figures
With such extensive knowledge of bovine anatomy, can you tell me if Frank Zappa was right? With a tongue like a cow, can she really make me go 'Wow!"?
some estimates put it on the order of being 80 times more powerful.
I don't see that quote in the AGU article, so I'm going to guess that comes from "Vice" ; quite why you'd take a figure from a website about prostitution over one from a geophysical union in a discussion over a science question, I don't understand.
It looks as if Vice's cut'n'pasters (I can't call them journalists) grabbed several figures from various sources and just said "up to [the highest]" without doing any checking on why they were getting a large range. From other sources, I'd have said that methane was about 23 times as powerful a greenhouse gas as CO2 ; upthread hyades1 says 25x ; meh to that difference. Where an 80-fold ratio comes from, I've no idea. That could be a figure for some CFCs (they are also potent greenhouse gasses as well as ozone-fuckers) ; it might be true for ethane or higher alkane gasses (minor components of some natural gas deposits) ; or it might just be a figure made up from whole cloth. but the 80x figure is clearly wrong.
The half life of methane in air (against oxidation to CO2) is around a decade ; there are probably considerable temperature effects in there, making an average a bit dodgy to measure. It's not centuries (we'd see it in the records of previous major releases of methane to the atmosphere, such as my bread and butter Palaeocene-Eocene Thermal Maximum ; it's not days (otherwise this plume would have oxidised away ; it's somewhere in between.
OTOH, because the leaks haven't been accurately measured (Could they be?),
Which part of the original article (first post in the thread) did you not read? Was it the bit that says
Frankenberg noted that the study demonstrates the unique role space-based measurements can play in monitoring greenhouse gases.
âoeSatellite data cannot be as accurate as ground-based estimates, but from space, there are no hiding places,â Frankenberg said.
So, if your angle gets to low values (choose where that is for yourself) , then you switch to using that approximation and cut out a large chink of calculation. Saves a lot of hassle. It's as basic as checking for "divide by zero" situations.
Ok, now we've exhausted the 10 beds at the hospital that are usable for quarantine. We've still got 150 patients with symptoms in the emergency room. Put them all in the same room?
Yes. that's what you have school sports halls etc for. You put them into the same room, using whatever beds, blankets etc you have from your emergency stores (you know - for fire, flood, typhoon or tornado ; whatever). And then you put armed guards on the entrances and perimeter of the site. You probably also call out the National Guard/ Territorial Army or whatever equivalent you have to supplement your firearm-trained police. And you take the "kid gloves" off.
That will get us another 5000 patients with the symptoms in the emergency room. Quarantine them? No place. Send them home? And we go another round.
This is why you come down, hard, on day one. you do not want round 2.
Within the quarantine area, you can manage patients. Re-assess them ; when results from round-one blood tests (it takes several days to test blood for Ebola antibodies), you can segregate the known-positives from their contact. But you do not let people leave until they've gone through the full isolation, quarantine and testing regime. That's why the guards are armed.
We do know how to contain disease outbreaks. Whether politicians and the people have the balls to take it is a separate question.
Look, I'm not going to fear monger here, but the fact is that if significant numbers of infected individuals start traveling around the globe we will not be able to maintain containment for long, even with all the resources that ultra-rich 1st world countries have at their disposal.
There's a fair chance that we've already crossed that particular Rubicon.
In high school we would HIDE during fire drills so we didn't have to stand around in the cold/rain/heat/whatever.
this should have been ineffective. the drill should have continued until a full muster had been accounted for. If that takes an hour and a half (I've seen fire drills on oil rigs that took that long) to get a good head count, that's fine. You then go back to normal operations and complete the school day. One and a half hours late.
the people who were responsible get kicked to shit on the way home. Quite rightly.
