Are You Using SPF Records? 263

gravyface writes "I've been setting up proper Sender Policy Framework records for all my clients for past year or so, hoping to either maintain or improve their 'reputation' in the email universe. However, there's a lot of IT admins I speak with who either haven't heard of SPF records or haven't bothered setting them up. How many of you are using SPF records for your mail domains? Does it help? How many anti-spam vendors out there use SPF records as part of their 'scorecard'?"

Comment I literally cannot tell if they are serious. (Score 3, Insightful) 106

I'm sorry, this looks like something that was thrown out of an early draft of Johnny Mnemonic:

adiabatic quantum algorithm by magnetically coupling superconducting loops called rf-squid flux qubits.

Not only can I not tell if they're serious, I can't even tell if that means anything.

The math they present, or even the math on the Wikipedia page for Grover's algorithm, is also completely beyond me. I blame Alan Turing for all of this: if he'd cracked Nazi codes with poetry instead of with math, I'd probably be able to understand computer science.

As it is, I have to assign a probability p=0.5 to Google posting another blog entry tomorrow in which they admit to making the whole thing up and being tempted to include a reference to "Cookie Monster's postulate" along side "Grover's algorithm".

Google Demonstrates Quantum Computer Image Search 106

An anonymous reader sends along this quote from New Scientist: "Google's web services may be considered cutting edge, but they run in warehouses filled with conventional computers. Now the search giant has revealed it is investigating the use of quantum computers to run its next generation of faster applications. Writing on Google's research blog this week, Hartmut Neven, head of its image recognition team, reveals that the Californian firm has for three years been quietly developing a quantum computer that can identify particular objects in a database of stills or video (PDF). Google has been doing this, Neven says, with D-Wave, a Canadian firm that has developed an on-chip array of quantum bits — or qubits — encoded in magnetically coupled superconducting loops."

Comment Re:LA may NOT be better (Score 1) 339

I work in south LA and in my experience, there are just as many people talking directly on their handset and checking their Blackberry, if not more. I just don't think it's being enforced. But really, it seems nearly impossible to enforce that law with any sort of efficacy. Just another useless law brought on by populist politicians...

Comment Re:Constant Noise (Score 2, Insightful) 1019

Exactly. Very repetitive music that covers much of the spectrum can be seen as a more enjoyable form of pink noise. The effect is to mask all other sounds you receive and to create an environment where no aural cues interrupt your attention. Once your brain has realized it's not going to receive interesting data from your ears it stops wasting focus on interpreting it.

There are very good reasons why people would need this. The "uniform noise environment" point has already been made. One poster noted that tinnitus sufferers need some kind of aural stimulus or they get hit by a distracting high-pitched squeal. Then there's a condition called hyperacusis - the sufferer is overly sensitive to sound, being easily distracted or perceiving sound as too loud earlier than most. A variant of this makes it hard to ignore any sound, even quiet ones - they automatically command the sufferer's attention. You can imagine what this does to the sufferer's concentration when someone nearby talks.

Developers need to dedicate as much mental capacity as possible to a given task, especially since they need to keep many different bits of information in their head at any time. This makes noise insulation a good idea. Noise-dampening headphones (in-ear phones or the big earmuff-types) can reduce reasonable external noise to a point where music or white noise at a sane volume will completely cancel most of it.

If music privileges are to be taken away, I recommend issuing passive noise-canceling gear to focus-oriented workers or installing pink noise generators to provide at least some form of noise suppression.

I recall a story that the ill-fated solid booster rockets could have and should have been built in one piece near the launch site, but they were farmed out to Hatch's home state of Utah for political reasons. Transportation from there meant that they had to be built in segments joined with O-rings.

Is my memory correct?

Mafia Wars CEO Brags About Scamming Users 251

jamie writes with a follow-up to our recent discussion of social gaming scams: "Mark Pincus, CEO of the company that brought us Mafia Wars, says: 'I did every horrible thing in the book just to get revenues right away. I mean, we gave our users poker chips if they downloaded this Zwinky toolbar, which was like, I don't know... I downloaded it once and couldn't get rid of it.'" TechCrunch also ran a interesting tell-all from the CEO of a company specializing in Facebook advertisements, who provided some details on similarly shady operations at the popular social networking site.

Voting Machine Attacks Proven To Be Practical 225

An anonymous reader writes "Every time a bunch of academics show vulnerabilities in electronic voting machines, critics complain that the attacks aren't realistic, that attackers won't have access to source code, or design documents, or be able to manipulate the hardware, etc. So this time a bunch of computer scientists from UCSD, Michigan, and Princeton offered a rebuttal. They completely own the AVC Advantage using no access to source code or design documents (PDF), and deliver a complete working attack in a plug-in cartridge that could be used by anyone with a few private minutes with the machine. Moreover, they came up with some cool tricks to do this on a machine protected against traditional code injection attacks (the AVC processor will only execute instructions from ROM). The research was presented at this week's USENIX EVT."

If you try to sell GPL software you really open up a can of worms in terms of ethical problems.

I still don't see why you think this. You and your hundreds of friends created a work under the GPL. Sale is clearly contemplated by the GPL. Are future developers required to assume that you didn't know what you were doing and to check with each of you to find out how you feel about something that's laid out in black and white in the license?

Amazon Pulls Purchased E-Book Copies of 1984 and Animal Farm 645

Oracle Goddess writes "In a story just dripping with irony, Amazon Kindle owners awoke this morning to discover that 1984 and Animal Farm had mysteriously disappeared from their e-book readers. These were books that they had bought and paid for, and thought they owned. Apparently the publisher changed its mind about offering an electronic edition, and apparently Amazon, whose business lives and dies by publisher happiness, caved. It electronically deleted all books by George Orwell from people's Kindles and credited their accounts for the price. Amazon customer service may or may not have responded to queries by stating, 'We've always been at war with Eastasia.'"

Wikipedia Moving From GFDL To Creative Commons License 90

FilterMapReduce writes "The Wikimedia Foundation has resolved to migrate the copyright licensing of all of its wiki projects, including Wikipedia, from the GNU Free Documentation License to the Creative Commons Attribution-Share Alike 3.0 License. The migration is scheduled to be completed on June 15. After the migration, reprints of material from the wikis will no longer require a full copy of the GFDL to be attached, and the attribution rules will require only a link to the wiki page. Also, material submitted after the migration cannot be forked with GFDL "invariant sections," which are impossible to incorporate back into a wiki in most cases. The GFDL version update that made the migration possible and the community vote that informed the decision were previously covered on Slashdot."

Quebec Says 'Non' To English-Only Video Games 554

daveofdoom writes "The French-Canadian government of Quebec is saying 'non' to English-only video games if French versions are available. 'It's causing a lot of consternation among retailers and gamers alike, who fear the rules will lead to delays in video games arriving in the province, and may not accomplish what the law intends, which is to promote and protect the French language.' This is a ridiculous rule, as game companies can simply stop creating French versions of games to bypass the restriction."

Roland Piquepaille Dies 288

overheardinpdx writes "I'm sad to report that longtime HPC technology pundit Roland Piquepaille (rpiquepa) died this past Tuesday. Many of you may know of him through his blog, his submissions to Slashdot, and his many years of software visualization work at SGI and Cray Research. I worked with Roland 20 years ago at Cray, where we both wrote tech stories for the company newsletter. With his focus on how new technologies modify our way of life, Roland was really doing Slashdot-type reporting before there was a World Wide Web. Rest in peace, Roland. You will be missed." The notice of Roland's passing was posted on the Cray Research alumni group on Linked-In by Matthias Fouquet-Lapar. There will be a ceremony on Monday Jan. 12, at 10:30 am Paris time, at Père Lachaise.
