Re: I was looking for something in the GigaWatt range, for reasons.
5 mW is the continuous output. Pulsed lasers get to 10 TW/cm² and higher, 1TW=10^15 mW.
The homepages of WordPress, Joomla and Drupal do not pass W3C's Markup Validation without errors. So why should I trust their products?
In the old days
IBM offered to double the capacity of their punch-card machines. A technician would come along and exchange the pulleys of a 1:1.41 drivebelt. Problem was that the company charged the full price of a new punch-card machine, because you could now handle twice as many cards.
Nolan had also consulted a biologist, the slogan whould not have been "THE END OF EARTH WILL NOT BE THE END OF US.", but "The end of us will not be the end of earth". After all, life on earth has been thriving for billions of years without us.".
Beer because yeast will survive us.
Sounds like a job for Joy Reidenberg, professor of anatomy at Mount Sinai School of Medicine in New York. She dissected large animals like stranded whales before.
Whois info on netmundial.org leads to GODADDY.ORG (Scottsdale, Arizona) as its sole owner. So it is just a commercial setup to be ignored.
Re: water pistol
Better: have two water pistols as backup, one filled with a solution of sodium monosulfide and one with a mild organic acid.
For corruption checking
a 32-bit CRC is sufficient. You can even compute it with a look-up table.
Security is indeed an other matter.
Re: Where's Uranus
Uranus, IJsselstein, The Netherlands. Estimated population 121.
Re: lunar Mach number
The illuminated side of the Moon (not to be confused with the near side) is bombarded by the solar wind with 5-80 protons/cm³ at ~200000K. The velocity of sound in hydrogen plasma (not H2 gas) at 200000K is approx. 57 km/s.
So 3800 miles/hour is 0.033 in lunar Mach numbers.
Over the decennia I had many bad experiences with WD drives. But they make several series (colours) with different MTBFs. Their high-end drives are reliable. Also Toshiba* claims a long MTBF for their drives.
BTW AFAIK the the quality of spinning rust is mainly determined by the quality of the ball bearings: initial submicron differences in diameter of the spheres have just to wear off.

Re: Good call
The video is here for all to see:
All power consumed by computers from the 25W human brain to a 6.3 MW Cray XC40 is dissipated. This in contrast to chemical processes like Haber-Bosch ammoniasynthesis (good for 5% of global energy use) where a large part ends up in the product.
The installation of the HPC at the Exeter Science Park will influence the local climate which it is supposed to forecast.
Will this be the begnning of selfconscious computers?
Re: How much weight...
An other way to make cars more fuel efficient
My late father improved the efficiency of the family cars, notably several Panhard PL 17's, by adding a retour pipe for cooled exhaust gases to the low pressure air-fuel mixture, controlled by a hand-operated valve. The pressure being measured with a vacuum gauge.
Increasing the pressure (and temperature) in the cylinders gave a more complete combustion for a wide range of loads.
BTW Panhard's forced air cooled boxer engines are not unlike aircraft engines with one instead of two sparking plugs per cylinder.
Tool use at Lockheed-Martin
At 41 seconds in the video you can see that the open end of a combination wrench is used to tighten a nut, how unprofessional.
The substantial problems with the stabiltity of a magnetised plasma decrease with increasing scale. There is a reason why ITER is the largest experiment for controlled nuclear fusion up to this day.
A mass of 2*10^30 kg hydrogen by itself is sufficient to initiate a stable fusion reaction and solve all our energy requirements.
No Undo function
I thought we had Twitter for that.
Re: Higher level languages are easier to set up at the price of slower runtimes.
Higher level languages are easier to set up at the price of longer runtimes.
I counted 137 links to adobe.com in the vanilla Adobe Reader9 for intellinux, but no links to adelogs.adobe.com or 18.104.22.168 ...... (killed it).

Re: the price of personal data
The survey asked an equivalent of "If your car is stolen, what would be its value on the black market?".
Both stealing cars and using personal data for a purpose it was not intended for are punishable by law. In the later case f.i. CELEX:31995L0046 'Directive 95/46/EC of the European Parliament and of the Council of 24 October 1995 on the protection of individuals with regard to the processing of personal data and on the free movement of such data', Official Journal L 281 , 23/11/1995 P. 0031 - 0050 and national laws like the Dutch 'Wet bescherming persoonsgegevens' supervised by http://www.dutchdpa.nl/ .
@Dave Bell, Re: MP3 compression
You might have a look at
where you can hear what MP3 (the MPEG1 Layer III audio codec, as defined in ISO 11172-3) discards by opening one of the links in the table with dBA values. It is pretty horrible.
My impression is that MP3 leaves the sound intact, but compromises the emotional impact. May be a boffin with access to an fMRI scanner can do some research on this.
Pictures or it did not happen
For the Hubble Space Telescope image of the M60-NGC4647 system see Figure 1 of the article by Anil C. Seth et al.: http://arxiv.org/pdf/1409.4769.pdf .
"M60-UCD1 is the nearly point-like image in the bottom right. The discovery of a black hole in M60-UCD1 provides evidence that it is the tidally stripped nucleus of a once larger galaxy. We note that NGC 4647 is at approximately the same distance as M60 but the two galaxies are not yet strongly interacting. The inset shows a zoomed version of the g band image of M60-UCD1 with contours showing the surface brightness in 1 mag/arcsec2 intervals."

Re: Hollerith cards in the pocket
Just for the sake of the argument, 1 TByte of data can be stored in a block of 30 m x 30 m x 30 m of punched cards. Mothballs not included.
Re: "you can still insert and play your very first commercially produced CD"
I remember a story form New Scientist that the very first CDs could not survive transport in the cargobay of an airplane, because the lower airpressure drew bubbles in the CD. Of course the problem was solved in subsequent pressings of CDs.
My coat is the one with the Hollerith cards in the pocket.
The video is far better with the terrestial sound turned off.
So someone forgot to put on their spacesuits. Doing their business they were naked of course.
Re: Why oh why etc.
Because the Swiss are prepared to pay for their telecom infrastructure, 1395 CHF (1524 USD) per person per year (figures 2012).
Travelling in Syria Johann Ludwig Burckhardt (1784-1817) mentions cardamom-flavoured coffee. It tastes quite well.

Re: Anybody know if the SLAs for Azure include chargebacks for loss of business?
Azure's SLA guarantees "at least 99.9% availability".
That is a downtime of 365.25*24*0.001 = 8 hours 46 minutes per annum.
Just a personal feeling
The video of the moving kilobots gives me the same itchy feelings as looking at an anthill.
1024 must be above some critical number.
I will wait till the 2^19Day.
Re: Sorry, too busy to check the details of the test right now but...
The test was done at atmospheric pressure (see my post above).
Re: Anomalous Thrust Production
From D.A. Brady et al.: "Testing was performed ... within a stainless steel vacuum chamber with the door closed but at ambient atmospheric pressure."
So it is not rocket science after all.
Re: Man reports strange object in the sky - turns out it was the moon
A well-known astronomer instructed his teenage daughter to answer the phone at full moon to ask whether callers who had spotted a UFO had also seen the Moon.
This usually settled the argument.
That I can read ElReg doesn't mean I can't read Chinese, all be it very slowly.
BTW the link leads to the video http://weibo.com/u/3957583411#_loginLayer_1405984877559 which suggests the hacker is using a mobile phone. The car is NOT moving.
May be there is just a little green man inside, you never know these days.
Re: When I hear "saccharine Disney charm" ...
I was happy to see a large rubber hammer in the video at 2:35.
Re: Experimental Procedure
IMHO the difference between run-of-the-mill programmers and an ace is so large that the experiment is useless.
Re: Are dildos allowed in Japan?
Dildos feature in the film A Lost Paradise after a novel of the same name by Junichi Watanabe, based on the true story of Sada Abe.

"I think I'll get a set of keycaps marked \"Any\" for the next user that asks where the Any key is."
I always use the Ctrl key for that.
Just a thought
What if the 'experiment' never took place and the publication was just a setup to see the response on Social Media.
Re: 50Hz hum randomiser
A working UPS (not in stand-by mode) is in effect a 50 Hz randomiser.
That you are paranoid does not mean they are not out to get you.
RFID (ISO 14443) working at a comfortable frequency of 13.56 MHz does what iFind claims to do.
