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: 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: 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 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.

Re: putting fission power sources in spacecraft
Not if 99% of rocket launches succeed. Nor if 99.9% of rocket launches succeed.
Now the failures only give a nice show and some smoke:
Astronomers can wait or a future generation will reap the results. Explore space, but there is no need to speed things up.
BTW the next tansit of Venus is in December 2117.
Re: Q: Is 0.999 recurring equal to 1.0
That is where L. E. J. Brouwer's mathematical philosophy of intuitionism kicks in. It simple forbids "Gedankenexperimente' as "0.999 recurring".
Far more interesting than the drunkard's walk is a Lévy flight. This is also a random walk, but now small steps are interspersed with sporadic very long steps.
Wandering albatrosses use this search strategy on their voyages on the largely empty ocean.
Tux because it is also a bird.
Re: HIRISE image...
I saw a dome until I viewed the picture with my head upside-down. The curious thing is I had no problem seeing the crater afterwards when I returned to my preferred viewing position.

Re: Scale independence
Julian Havel explains Benford's Law in Ch. 14 "It's a Logarithmic World" of his excellent book "Gamma, exploring Euler's constant".
BTW, Benford's Law also holds for binary numbers: expect the number of zeros to be double the number of ones. Try it.

Has USPTO also granted a patent to photograph a black cat in a coal cellar at midnight?
Return of the Mololov-cocktail
Surround vision is most useful in urban warefare. A shotgun or petrol bomb can easily disable an armored vehicle which relies on Oculus Rift goggles. In a 'real' war it will be knocked down by the first shell landing near the tank.
Security by obscurity
Secure encryption is only possible when the key is longer than the message.
During WW II "Die Rote Kapelle" used for its daily radio transmissions from Brussels to the Kremlin an antiquarian unpublished roman as its codebook.
It is unclear how Chadder shares its key(s), how they are generated and what they are.
No, it is not a PARASITE
Caenorhabditis elegans, including the Australian strains, are free-living non-parasitic roundworms.
@Kwabena Boahen: "you have to know how the brain works to program one of these"
The whole point of neural networks is that you do not have to program them.
You just train them to give the right response.
