As a comparison for the non-astronomers:
In college, we had a pretty sweet 0.8m diameter scope. The limiting resolution of that was about 12 magnitude. Magnitude goes up as powers of ten.
Just a minor nit magnitude goes up in units of ~2.5.
Assuming 1mm2 dots
A4 sheet of paper 210 Ã-- 297mm = 62370mm2 = 7796 bytes call it 8kb = 62500 pages(double sided)
Encoding with 16 colors for 4 bytes per pixel = 32kb/page ~ 15000 pages
reduce the pixel size to.25mm = 256kb/page ~ 1900 pages
I'd think one could reasonably expect that 16 colors and.25mm dots would be readable more or less indefinitely
smaller pixels and more colors would mean fewer pages but a higher chance of corruption...
How low could one go? Printing to film at say 4000dpi? ~ 160dpmm ~ 1.2 pages (single sided)
and that just to store 1Mb if he is using a DVD that suggests gigabyte files > 800 sheets per Gb
doubling the number of colors encoding would half the number of sheets. then there is the faff of reading the sheets
Compare and contrast putting the data on an archival server with an offsite backup
and migrating to a new server every 5 years
Given that the first infects were recognized in 1984, I think the "selective pressure" is not a evolutionary one, as there just have not been enough generations. You have to factor in that the number of infected grew significantly, so the decrease of faster-killing virus variants may just stem from the fact that their hosts died earlier decreasing their share whereas that didn't happened for slower-killing virus.
That'd be without passing on to a newer generation of virii that has been selected due to fitting better (which will occur later, I'm sure).
Then on the other hand, I'm no biologist/physician:-)
(Very roughly) you only need about 10 generations so see a significant evolutionary change and HIV mutates at a frightening rate, (one of the reasons that it is so hard to treat is that if you treat a patent with a HIV drug there is always one virus in the patent with a protective mutation). Anyway getting back to the point its not just death that exerts a selective pressure its how ill it makes the patent. If your bed ridden with pneumonia your not out on the pull spreading viruses.
The concept behind a 'gravity tractor' is fatally flawed. Gravity is the weakest force in the universe, the only reason it matters to us is that there's enough mass making up Earth to make it worth paying attention to.
Instead of sitting next to asteroid, it'd be far more effective to dock the probe and push directly using the vaunted ion thrusters.
TANSTAAFL, folks.
Asteroids tumble, this makes it hard to land and worse means you can only use the vaunted ion thrusters when there pointing in the right direction
My favorite example is chicken. In the US, cheap factory farm raised chicken has an almost spongy consistency, and tastes rather bland. Organic, free range chicken is much tougher and flavorful,
Is it just possible that its the 'Free range' part that results in the better flavour/texture?

I imagine they'll make baby monitors actually run on Wifi.
Upon reading that I couldn't help but think what a horrible idea that would be. I can foresee no end of problems with making that work reliably. People need something that just works when the turn it on.
Hmmm config could be made very simple indeed, physically dock the two devices to exchange keys
and a unique SSID, the receiver could use the SSID to search for the transmitter. Stick signal locked and signal strength lights on the receiver so the user can best position the unit.
IMHO it would be easy to set up that an analog baby monitor which I've never had much success with (they tend to just sit there and hiss), Signal encryption is another benifit and best of all
when baby is all grown up you get a new doodad to stick on the home network!
Could that be because the navy was there to provide medical facilities and treatment to the people on American Samoa?
It seems unlikely that 1918 medicine could do anything more than bedrest and drip feeding, I don't think this would have had much effect on the mortality rate. The 1918 flu apparently killed by triggering a massive immune responce, so it affected otherwise healthy young adults and not the very young, old and immunocompromised who normally die from flu.
I thing the grandparent has the selection mechanism the wrong way round. its not that:-
"you will avoid people you know to be sick, and hence you are more likely to be infected by a less ill person.".
Consider two viruses one kills its host in 3 days and one in 6 days. The second one has twice the opportunities to transmit to new hosts, more offspring = clear selective advantage. In fact killing/incapacitating the host is a really bad idea, its much more advantageous to keep your host healthy and mobile so they keep circulating in the community and not hiding in bed not transmitting to anyone.
but it looks like google's flu trends is based off who searches for flu and flu like words. how can that be accurate in the current situation we're in?
It should still work... to a first approximation media coverage would cause a uniform increase is searches across the country. A flu outbreak should still create a hot spot though sensitivity would be lost as the signal/noise ratio goes pearshaped.
Twitter is becomming the butt of jokes in the mainstream media this is not happening because the media are scared of Twitter. Its because Twitter has become a byword for ill informed content and mob mentality to the extent that I've heard stand up comedians can get a laugh out of mocking it.
This is not good for Twitter. It needs to reinvent itself fast or it will die a victim of its own success.

That or some joker changes the audio skin for 'Toontown'
I've always assumed the whoosh was synthesized by the ships systems as a audio representation of the local battlespace
So by making 'space mining' feasible it makes itself obsolete, you say that like its a bad thing..

I name computers after girls I've fucked.
Right hand and left hand?
What if I want three computers?
Fleshlight (and you can name 3+ machines because your can build them with different permutations of colour, texture etc .... or so I'm told)
I don't think I could take BSG shakeycam footage on a big screen!
Indeed it did

Q: How many Microsoft engineers does it take to change a light bulb?
A: None. Bill Gates will just redefine Darkness(TM) as the new industry standard.
Offer lower rates if the building has been properly built
He just declares flooding as the new international standard
And not Mt Lushmore?
No thats Lush as verdant or inebriated
Like the mountain in South Dakota that bears an uncanny resemblance to former presidents...
You wouldn't by any chance be referring to Mount Rushmore, would you?
No, he's talking about Mount Tushmore, easy mistake to make its not on many tourist maps

Panic, unlike influenza, can be "spread" only to those who willingly accept it.
Unfortunately if contracted by someone in authority your still going to catch it effects :-(
