Ah, a steampunk VDU. That is the Machina Cryptologica of Athanasius Kircher S.J., described in his book Magnes, sive arte magnetica (The Magnet or the Magnetic Art), Cologne 1643.
See "Athanasius Kircher, The Last Man Who Knew Everything" by Paula Findlen (ed.), Figure 11.1.
Building TrueCrypt from the tarball TrueCrypt_7.1a_Source.tar.gz comes with several requirements inter alia:
RSA Security Inc. PKCS #11 Cryptographic Token Interface (Cryptoki) 2.20 header files (available at ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-11/v2-20).
An audit should take this into account. BTW FTP is blocked by my firewall by default.
If one or more of my friends-in-the-Google-sense has had a meeting with Staphylococcus aureus in that nice restaurant around the corner, this new "service" of Google would only give me the +1s ....
The talking heads in http://www.youtube.com/watch?v=6aZbJS6LZbs (1108797 views) are not lipsync.
The M-Block robots in http://www.youtube.com/watch?v=mOqjFa4RskA (76731 views) are, well, just cubes.
So the (fascinating) image and sound are OK.
The BCC apparently has 106 40+ year old videotapes labeled "Dr Who".
If they can find equipment to run the tapes - The Center for Art and Media in Karlsruhe may be a good start -, the tapes may well turn out to be unplayable and/or disintegrate at the first attempt to digitise them.
Conservation of magnetic tape is a serious problem. According to Sarah Everts
(New Scientist, 24 Aug 2013) some 200 million hours of culturally valuable audiovisual content is in danger of disappearing entirely.
May be we should equate digitising analog videotapes with baking Babylonian clay
tablets by accidental fire which conserved them for millennia.
Arabic text is written right-to-left, but numbers are written left-to-right
in the opposite direction of the script (Teach yourself Arabic by J.R. Smart, page 33).
Osama bin Laden was not a goat farmer.
The bin Laden family made $5 billion in the construction industry, of which Osama later inherited around $25-30 million.
Upvoted you anyway.
HP mini's, I worked with in the 1970's, used 8-bit paper tape.
The reader could scan the tape at full speed and halt at a given byte by activating a magnetic clamp.
Given the kinetic energy of the moving tape and the speed of the action working on a small area the paper should be scorched.
What in stead happened was that the tape was clamped and a pair of shockwaves was send through the tape which dissipated without damaging the tape.
Alan Turing was cremated at Woking Crematorium on 12 June 1954. Turing's ashes were scattered there. Otherwise Turing has plenty of reasons to turn in his grave
In the 1990s the Dutch retail chain "Kruitvat" sold low-cost recordable CDs.
When a colleague showed me the physical location of the sectors where error correction was necessary a few months after recording, I could read "Kruitvat", exactly matching the logo proudly printed on the CD in the wrong kind of ink.
NASA uses a variety of methods to measure, control and reduce spacecraft microbial contamination for planetary protection purposes. http://planetaryprotection.nasa.gov/methods
I am afraid that the PocketSpacecaft project as proposed will upset the delicate microbial balance on the Moon.
There is a story that a class of KLM stewardesses, first confronted with a computer mouse (I personally know a KLM stewardess who is quite familial with the animal variant, al least her cat is) tried to move them over the screen like a lightpen, a device predating the mouse.
Well, due to the rotation of The Galaxy alone NEXT and earth with it moved 43200 million km in 48 kh.
Hb. Chem.& Phys. 53rd Ed., E41 gives the velocity of sound in m/s at 25+t°C as:
Water (distilled): 1496.7+2.4t
--> 37.5% ethanol, 62.5% water 1388+0t (estimated)
So Turing was right. Gin (and Vodka) are OK. Vermouth (16-18% ABV) won't work in a delay line.
We need a double-blind test - definitely.

Please, do not compare the WiSee technology, impressive as it is, with a modern radar system like that of the S-300.
"You always perform a startup sequence of gestures to get into the control system before sending the real gesture commands. The startup squence (sic) could be relatively long so false positives become rare cases. Such a startup sequence can also serve as your personal password."
There is no way to see you entered the RIGHT startup sequence before you send the commands, in particular if you are not in the same room as the WiSee enabled Wi-Fi router.
"WiSee technology uses multiple antennas to focus on one user to detect the person's gesture."
There is no way to track a person.
" \"I hope more people find out about Alamogordo through this opportunity that we have to unearth the Atari games in the landfill,\" Alamogordo mayor Susie Galea said."
I thought Alamogordo was already worldfamous/notorious by the Pu239 from the Trinity test burried there.
Galaxies do not have to give way. They just attract each other - gravity you know - and merge.
Cars, other vehicles and pedestrians get their shape from electromagnetic forces and do not merge.
Tulipomania is small fish compared to trading a company with 178 employees, including the cat, for 1100000000.00 USD.
Even in capital intensive petrochemical industry investments are in general below 1 million USD per employee.
No in-picture timestamps (with eight minute ambiguity of course).
There are no molecules at a WD, that severely restricts the choice of medicines.
Only elemental iodine as a disinfectant comes to mind.
From the Dutch law on firearms (Wet wapens en munitie, translated):
"Category I 7° other objects that can form a serious personal threat as indicated by Our Minister or that look like a weapon appropriate for threat or extortion."
So no need for a Liberator here, just print your Walther P5 in soap and paint it black.
BTW the Liberator seems as good as the gun that exploded and killed James II of Scotland at the siege of Roxburgh in 1460.
The <real> news is the death of Herschel.
Can't you open most DVD-players with a paperclip and hide the contrabande?
Wait, in the DPRK the only people who have ever seen, let alone bend, a paperclip are probably army generals or nuclear engineers.
Obersturmbannführer (as in "Banner") not Übersturmbahnführer (as in "Eisenbahn").
See http://de.wikipedia.org/wiki/Sturmbannf%C3%BChrer. Upvoted you anyway.
Designers of Space Elevators should not ignore the Coriolis-force, unless they are writing a work of fiction.
Although (re)reading I.F. Stone's "The Hidden History of the Korean War" is very interesting.
You should have sold the iPad at auction.
In November 2006, Pollock's No. 5, 1948 became the world's most expensive painting, when it was sold privately to an undisclosed buyer for the sum of $140,000,000.
Installing software on a system you do not know and execute it on said system of which you do not know the purpose is a crime FULL STOP
Cattle get more care than dogs and cats that are dumped by their owners when they go on holiday. After all they are the farmers capital and are given names like "Betsy24" - at least in Holland.
The INO magnet will be housed 1300 meters below the carpark.
Moreover the Tata Nano has an aluminium engine ....
Why not just send a couple of radiationhardened ants on a flyby around Mars?
They 'll inherit the earth anyway.
http://curiosityrover.com/imgpoint.php?name=0173MR0926020000E1_DXXX shows that the image covers the path taken by Curiosity.
The object seems to be something the rover 'lost', deliberately or otherwise.
The problem is mass production: in 1986 the price of a Canon PJ-1080A Colour Ink-Jet printer (Made in Japan) was 2644.18 Hfl., incl. 19% VAT (equivalent to 1199.88 Euro).
The serial number of my PJ-1080A is 801057, but I doubt whether 801057 printers were made. The resolution was only 85 dpi.
May be converting it to a 3D-printer is a nice hobby project.
The research paper mentioned describes calculations for a model working at a single microwave frequency ("wavelength 30mm at the frequency of 10 GHz."). No physical experiments were involved.
Jie Sun et al., "Large-scale nanophotonic phased array" http://www.nature.com/nature/journal/v493/n7431/full shows a more interesting innovation from MIT in Cambridge Mass. working at optical wavelengths.
One backup is no backup.
On IBC 2011 NHK (Japan Broadcasting Corporation) had a demo of their Super Hi-Vision system (7680x4350 pixels, intended horizontal viewing angle 100°).
I was impressed and thought I saw the future of TV.
However when I compared the image on the 85 inch LCD with the lady in front of the camera, I noticed that the colour reproduction, especially of skincolour, was very poor.
"Hydrogen has twice the lifting capability [of helium] (H2 molecules are nearly twice the volume, and only half the mass)."
1) The lifting capacity is the difference between the density of air and the density of the lifting gas.
Hydrogen: 1.293-0.0899= 1.2031 kg/m3
Helium: 1.293-0.1785= 1.1145 kg/m3
(at 1 bar, 0° C)
2) The volume of H2 molecules is irrelevant. The number of molecules present in equal volumes of gases at the same temperature and pressure are equal (Avogadro's principle).

The black LED does not exist as it requires a radiating body at 0 K, which is impossible.
Does anyone remember mercury?
Fill a rubber tube with mercury and stretch it. Measure the electric resistance and you know the length.
Used to have some interesting applications in medical research.
You forgot the ignition coil between the car battery and the genitals.
