Submission + - P=NP and More

FredK writes: I have recently posted a proof/algorithm that P=NP and more. I'm going to see if crowd sourced refereeing can get me past the the road blocks I've encountered. Details at http://mathalacarte.com/pnp

Submission + - ESR: Radical Feminists Are Attempting to Frame Linus, Others for Sexual Assault (ibiblio.org)

_KiTA_ writes: Open Source Pioneer Eric S. Raymond has revealed explosive allegations on his blog, claiming that he has a source with evidence that the Ada Initiative, a tech initiative designed to support women in open source, has been attempting to frame Linus Torvalds and other high profile members of the Linux and Open Source community for sexual assault. Linus has been noted for never being alone at conferences as of late, apparently this is a defensive move due to repeated attempts to "scalp" him — getting him alone and then immediately pushing a fake claim of sexual harassment or assault to either have him arrested or pulled off Linux development.

Possibily related to October's Linux Kernel Dev Sarah Sharp Quits, Citing 'Brutal' Communications Style story on how feminist Sarah Sharp took words out of context to try and suggest Linus and Greg were being aggressive monsters on the Kernel Mailing List — something she equates with physical violence on her blog.

Sarah Sharp is a member of the Ada Initiative's Advisory Board, the group that is apparently behind the attempt to frame Linus, among others, for sexual misconduct.

Submission + - Tips for Securing Your Secure Shell

jones_supa writes: As you may have heard, NSA has had some success in cracking Secure Shell (SSH) connections. To respond to these risks, a guide written by Stribika tries to help you make your shell as robust as possible. The two main concepts are to make the crypto harder and make stealing keys impossible. So prepare a cup of coffee and read the tutorial carefully to see what could be improved in your configuration. Stribika gives also some extra security tips: don't install what you don't need as any code line can introduce a bug, use the kind of open source code that has actually been reviewed, keep your software up to date, and use exploit mitigation technologies.

Submission + - Bad News Everybody!

fustakrakich writes: It appears you can no longer go back more than 66 pages in front page news stories, where previously you could go all the way back to 1999. If this is actually a permanent thing, then Slashdot is truly dead, and it is no longer worth lingering around here. Shame on you, Dice. You are horrible people. You killed a great web site. All to make space for the spammers in the Journal section.

If this is only temporary, I take back everything.

Thank you

Submission + - Satochi Nakamoto's email address satoshin@gmx.com is compromised (mineforeman.com)

ASDFnz writes: Satochi Nakamoto, much revered and currently missing inventor of bitcoin seems to have had his email address compromised by an unknown agent.

You may or not remember, Satochi exclusively used one email address when he was active in the bitcoin community, satoshin@gmx.com. If you have a look at the original bitcoin whitepaper you will find it there at the top just under the title. He also usually signed his correspondence with his PGP signature.

Earlier today, the head administrator of Bitcointalk Theymos received an email from Satochi’s email address that appeared to originate form GMX’s servers and made a post on the bitcointalk forums saying that he had received an email from the address without Satochi's PGP Signature.

Later developments have the unknown agent posting to other Satochi accounts.

Submission + - Reddit Moderator Outs Reddit Admins (soundcloud.com) 8

Khyber writes: While the censorship is strong over at Reddit, details from a (former) moderator of one of the largest subreddits on the site have been leaked in the form of an an audio recording of a Skype conversation between an unidentified journalist and the moderator himself. User posts are being deleted rapidly from Reddit over in the /r/gaming subreddit, users are being shadowbanned, or hard-banned. (I've had my account dropped.) Really interesting parts of the 50-minute long audio sit around ~10:30 and ~26 minute marks, where the moderator details threats made against him and other moderators, and also a bit near the end regarding their censorship/spam control tools, and how anyone can effectively be banned for any made up reason, commonly-used ones being vote manipulation, brigading, and alt account creation. There is also talk about how subreddits for encryption get monitored much more closely and censored much more often than larger subreddits, such as /r/gaming.

As someone I know has put it, "...given that Reddit says that it views itself as a government for a new type of community, this is disturbing."

Submission + - GitHub takes down parody 'C Plus Equality' programming language 1

FooAtWFU writes: Some clowns and jokers over at 4chan thought it would be a funny idea to put together a web page for a programming language named "C Plus Equality" as a parody of feminism, dismissing OOP as "objectifying" and inheritance as "a tool of the patriarchy". But this parody was apparently too hot to host at Github, which took down the original Github repository after receiving criticism on Twitter, prompting a backlash and inquiry into the role of free speech and censorship on Github's platform. The project has since found a new home on BitBucket, at least for the time being.

Submission + - Bitcoin blockchain forked by backward-compatibility issue (bitcointalk.org)

jhantin writes: The Bitcoin blockchain has forked due to a lurking backward-compatibility issue: versions older than 0.8 do not properly handle blocks larger than about 500k, and Slush's pool mined a 974k block today. The problem is that not all mining operations are on 0.8; blocks are being generated by a mix of several different versions of the daemon, each making its own decision as to which of the two forks is preferable to extend, and older versions refuse to honor or extend from a block of this size.

The consensus on #bitcoin-dev is damage control: miners need to mine on pre-0.8 code so the backward-compatible fork will outgrow and thus dominate the compatibility-breaking one; merchants need to stop accepting transactions until the network re-converges on the backward-compatible fork of the chain; and average users can ignore the warning that they are out of sync and need to upgrade.

Submission + - How to use Freenet for social networking (wordpress.com)

Wonko the Sane writes: Freenet has been around for a long time but one of the things that has held it back is a lack of user-friendly documentation. At last, that seems to be changing. This blogger has put together a detailed instruction manual for installing Freenet and setting up secure social networking. Crypto-anarchism is now easy enough for Aunt Tillie.

Submission + - Artificial blood vessels created on a 3D printer (bbc.co.uk)

rallymatte writes: "A team at Fraunhofer Institute in Germany has managed to create artificial blood vessels with a 3D printer that may come to be used for transplants of lab-created organs. From the article:
"To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation — shining intense laser beams onto the material to stimulate the molecules in a very small focus point.""

Submission + - Your Worst Radiological Nightmare (militantlibertarian.org)

Wonko the Sane writes: A dirty bomb attack might be easier to pull off and harder to prevent than the public has been lead to believe:

Think you know about radiological dirty bombs? You know, the usual: easily-detected, a suicide mission for the operator, etc. All of these are comforting things that we are told to believe (usually by some perky blonde after talking about what star is in jail for what). Think again. I've sat on the idea in this article for over two years now since stumbling across hints of it while researching Starving the Monkeys . Recently I’ve come across confirmations from multiple sources that, yes, the idea is relatively widespread. It is a well-kept secret, but only from you. Rest uneasy, the bad guys already know about this idea.

Submission + - Time Traveller reported (nzherald.co.nz) 2

Kittenman writes: The NZ Herald is reporting that an Irish filmmaker, George Clarke, has noticed someone using a cellphone in the 'special features' section of the DVD 'The Circus', a Charlie Chaplin movie filmed in 1928. The cellphone is (reportedly) visible in the "unused footage" section. Clarke states: "The only conclusion I can come to — which sounds absolutely ridiculous I'm sure, to some people — is it's a time traveller,". Other conclusions are also possible, no doubt. One also wonders what network the traveller was using in the 1920s. Or maybe it was a satellite phone — which raises other issues. Or maybe it was something else altogether. Most remarkable is that not only that a person has an obscure Chaplin movie on DVD but that they also scanned the 'special features'.

Mimicking Electric Eel Cells 71

An anonymous reader writes "A team of US researchers has asked the following question in the new field of systems biology: 'Do we understand how a cell produces electricity well enough to design one, and to optimize that design?' They believe it should be possible to build artificial cells replicating the electrical behavior of electric eel cells. In fact, such artificial cells could deliver better performance — as much as 40% more energy than real eel cells, a computer model suggests. They could be used to power medical implants and other small devices."
