For my part, I assume the site "redesign" is just a migration off of Slashcode onto the same web publishing engine that the rest of DICE's properties use,

That's my suspicion as well. I noticed some other sites have oddly similar design (especially in the details). Take a look at NPR's blogs, for example:

Notice any similarities? Looks a lot different under the hood though so I could be wrong. Mind you there's so much crap going on behind the scenes on the /. beta that it's hard to say for sure.

Submission + - Quarks Know Their Left From Their Right (sciencemag.org)

Submitted by sciencehabit
sciencehabit writes: How an electron interacts with other matter depends on which way it's spinning as it zips along—to the right like a football thrown by a right-handed quarterback or the left like a pigskin thrown by a lefty. Now, physicists have confirmed that quarks—the particles that join in trios to form the protons and neutrons in atomic nuclei—exhibit the same asymmetry.The result could give physics a new weapon in the grand hunt for new particles and forces. Or they can search for subtle hints of exotic new things beyond their tried-and-true standard model by studying familiar particles in great detail. In the latter approach, the new experiment gives physicists a way to probe for certain kinds of new forces.

Submission + - The Curious MInd of Ada Lovelace

Submitted by Anonymous Coward
An anonymous reader writes: Going beyond the usual soundbites about Ada Lovelace, Amy Jollymore explores the life of the worlds first programmer: "When I heard that Ada Lovelace Day was coming, I questioned myself, "What do I actually know about Ada Lovelace?" The sum total of my knowledge: Ada was the first woman programmer and the Department of Defense honored her contributions to computation in 1979 by naming its common programming language Ada.
A few Ada biographies later, I know Augusta Ada Lovelace to be an incredibly complex woman with a painful life story, one in which math, shame, and illness were continuously resurfacing themes. Despite all, Ada tirelessly pursued her passion for mathematics, making her contributions to computing undeniable and her genius all the more clear. Her accomplishments continue to serve as an inspiration to women throughout the world."

Submission + - BBC Unveil Newly Discovered Dr.Who episodes (bbc.co.uk) 1

Submitted by BigBadBus
BigBadBus writes: Putting paid to months of speculation, the BBC announced at a press conference today that it had recovered 9 previously lost episodes of Dr.Who, from the Patrick Troughton era (1966-69). The episodes complete "The Enemy of the World" and almost complete "The Web of Fear" (leaving one episode outstanding). The episodes were found in a relay station in Nigeria by Phillip Morris; previously Nigeria had been checked and had returned 6 lost episodes in 1984. The episodes are now available from UK and US iTune stores and can be for pre-ordered from Amazon.co.uk

Submission + - FlameStower: Charge Your Mobile Device with Fire (lensvid.com)

Submitted by Iddo Genuth
Iddo Genuth writes: If you love to go on camping trips and want to charge your mobile phone, tablet or even camera there is a new solution on the way which can do that anywhere day or night and all you need to do is light a little fire and have a few drops of water. The FlameStower efficiently captures excess heat from a gas burner or campfire to charge almost any USB-powered device: cell phones, GPS units and even cameras by using the thermal deferential between the fire and water and the whole thing is already collecting money on Kickstarter (and if you are really handy you can even make a DIY version yourself).

Submission + - First few Doctor Who episodes may fall to public domain next year

Submitted by wmr89502270
wmr89502270 writes: Doctor Who is celebrating its 50th anniversery this year. The special The Day of The Doctor will be brocast simultaneously in over 75 countries and hundreds of cinemas in the UK and across the world also plan to screen the hotly anticipated special episode simultaneously in full 3D. Accroding to Copyright law of the United Kingdom, the copyright in a broadcast programme expires 50 years from the end of the year in which it is broadcast, which means the first episodes will fall to public domain next year.

Are you familiar with Inline::C? It lets you write Perl functions in C. The C code lives in the same file as the Perl code and is transparently compiled on an as-needed basis. Best of both worlds kind of thing. BTW, I write my image processing code the same as you: C for heavy lifting and Perl for all the rest.

We have, they're called multi-level cells. They improve memory density but at a cost of increased complexity, lower speed, higher susceptibility to noise, higher power consumption, and decreased lifetime. Decimal arithmetic was used on at least one early computer (ENIAC) but binary circuits were found to be much simpler to design and implement. The only modern non-binary digital computer that I'm aware of is the Soviet Setun that used ternary (tri-state) logic.

A good defense against this kind of attack is to 1) use a per-page nonce, 2) use an HTTP POST for all page loads, and 3) use HTTPS for all traffic. On every page load the nonce present in the POSTed form is compared to the nonce stored on the server. If the nonces match then the page along with a new nonce is generated and returned to the client; the new nonce also replaces the old one on the server side. If the nonces do not match then an error is returned. Simply knowing the page's URL does not allow one to retrieve the page even if one is seen as being logged in (e.g. via a cookie). In addition, this technique provides a good deal of defense against replay attacks and session hijacking. Note, however, that this technique can be partially defeated if the attacker has some other way of retrieving the source of the actual page displayed in the user's browser. A full security analysis is left as an exercise for the reader ;^)
