At any rate, I think it's so trivial to get around that I doubt anyone actively trying to circumvent it has any problems whatsoever. Though I suppose it migth keep a few people from ending up somewhere they didn't intend to...
I think that is the crux of the matter. I can certainly understand why grandma doesn't want to see kiddie porn. So, voluntary filtering - opt in - is fine. But mandatory is, to my way of thinking, a slippery slope to say the least!!

PS3Penguin
PS3Penguin writes "Sandia National Laboratories has a solution to the oil shortage / excess CO2 of a gas driven economy.
Reverse the process!
Sandia's synthetic-fuel recipe: Mix CO2 , water; heat with sun EEtimes has a two page article on the CR5 Reactor. It started out as a clever way to generate hydrogen from the power of the sun + water. It was later realized the process could be (or should be) extended to make a synthetic fuel that was compatible with standard combustion engines. To quote the article "One way to look at it is as reverse combustion — taking heat from the sun, adding it to carbon dioxide and water, and making a synthetic fuel from them," said Diver."

greasyguide writes "According to Oxford Scientists, parallel universes really do exist. Many scientists argue that time travel undermines the idea of cause and effect to create paradoxes. According to David Deutsch at Oxford, the existence of parallel worlds offers a way around these paradoxes. In a recent article in New Scientist, parallel universe make quantum sense to many modern day physicists. Andy Albrecht at the University of California at Davis, calls this as one of the most important works in scientific history. http://www.associatedcontent.com/article/458816/time_travel_to_a_parallel_universe.html"

Data Storage

+ - Why CNBC chose Apple for its primary storage-> 1

Submitted by
Ian Lamont
Ian Lamont writes "Computerworld has written about CNBC and its storage infrastructure. Instead of relying on bigger vendors like NetApp or EMC for its primary storage, the cable news channel turned to an Apple Xsan. It's one of the few Apple SANs that the writer has seen in a data center of this size: 'Most corporations simply don't trust Apple — primarily because their infrastructure is Windows and Unix — to put it in their data center, much less to use it for their primary network storage,' he writes. Part of the reason why CNBC chose Apple is the CNBC graphics team uses Macs for a lot of their work, but cost and scalability figured into their choice, as well. There's a brief video interview accompanying the story, featuring CNBC's graphics engineer explaining the Xsan setup."

Submitted by malachiorion
malachiorion (1205130) writes "It's no Roswell, but the Tunguska event, a June 30, 1908, explosion that cleared an 800-sq.-mi. swath of Siberian forest, remains a hot topic for the X-Files set. Was it a UFO crash? An alien weapons test? Now, Sandia National Laboratories has released its own explanation for the event. Using supercomputers to create a 3D simulation of the explosion, the Department of Energy-funded nuke lab determined that Tunguska was, indeed, the result of a relatively small asteroid. Even if you don't care in the slightest, the terrifying simulation videos are well worth checking out."

Submitted by
LionMage
LionMage writes "This morning, I saw a disturbing article on the BBC about Western Digital caving in to Hollywood interests and prohibiting all sharing of music and audio files using their products. Buried deep in the article are the details: this blocking pertains to NAS products, and specifically to Western Digital's Access Anywhere software. Over 30 file types are blocked by the software. The software does not make allowances if, for example, you are the rights holder and are allowing distribution of your own content.

More coverage of this can be found elsewhere around the web."

+ - Nanotube-Excreting Bacteria Allow Mass Production->

Submitted by
Invisible Pink Unicorn
Invisible Pink Unicorn writes "Engineers at the University of California, Riverside have found semiconducting nanotubes produced by living bacteria — a discovery that could help in the creation of a new generation of nanoelectronic devices. According to the lead researcher, 'We have shown that a jar with a bug in it can create potentially useful nanostructures.' This is the first time nanotubes have been shown to be produced by biological rather than chemical means. This research began when they observed something unexpected happening while attempting to clean up arsenic contamination using the metal-reducing bacterium Shewanella. In a process that is not yet fully understood, the bacterium secretes polysacarides that seem to produce the template for the arsenic-sulfide nanotubes. These nanotubes behave as metals with electrical and photoconductive properties useful in nanoelectronics. The article abstract is available from the Proceedings of the National Academy of Sciences."

Space

+ - Astronauts test sex in space 3

Submitted by Arevazi
Arevazi (935715) writes "The Guardian has a story about a book confirming that US and Russian astronauts have had sex in space for research programmes. The book (The Final Mission: Mir, The Human Adventure by Pierre Kohler) cites a confidential Nasa report on a space shuttle mission in 1996. A project codenamed STS-XX was to explore sexual positions possible in a weightless atmosphere. The result: only four positions were found possible without "mechanical assistance". One of the principal findings was that the classic so-called missionary position, which is so easy on earth when gravity pushes one downwards, is simply not possible."
Google

Submitted by
Stony Stevenson
Stony Stevenson writes "In response to a concerted effort by cyber criminals to infect the computers of Google users with malware and make them unwitting partners in crime, Google has apparently purged tens of thousands of malicious Web pages from its index. Alex Eckelberry, CEO of Sunbelt Software, noted that many search results on Google led to malicious Web pages that expose visitors to exploits that can compromise vulnerable systems. Sunbelt published a list of search terms that returned malicious pages, the result of search engine optimization (SEO) campaigns by cyber criminals to get their pages prominently ranked in Google — Sunbelt refers to this as "SEO poisoning."

Let's hope Google has done its research and hasn't purged legitimate sites."

Space

+ - Mission to Mars: Possible or Impossible?

Submitted by BlueMerle
BlueMerle (1161489) writes "Mission to Mars: I've been watching Mars Rising on SciCh and find myself asking, is it possible? And in almost every case my answer is No! Not under current conditions, with existing, think proven, technology.

Gravity: Without some sort of artificial gravity the crew would most likely not be able to stand when they reached Mars. And to the best of my knowledge there are no actual plans for building any type of spacecraft that has the ability to generate artificial gravity. There are many ideas, and CGI renderings of possibilities, but no actual blueprints or technical drawings, and there is certainly nothing that exists to prove the concept.

My best guess, 25 — 30 years of testing and billions of dollars until a viable solution.

Shielding: Without adequate shielding from intense radiation the crew may not survive the trip. This is perhaps the easiest problem to solve. There are currently several research projects working on this issue, and some have shown real progress without having to build a 3 foot thick lead room.

My best guess, 2 — 10 years with relatively minimal funding.. tens of millions.

Human Factor: Is it really possible to put 6 or 8 people in a spacecraft the size of a small apartment and lock them in for up to 2.5 years (round trip, including time on Mars)? This in my opinion is the biggest single obstacle to be overcome. Oh and BTW, personal hygiene consists of a small towelette with 2 or 3 drops of water. And you may not get even that on a daily basis! The nastiest bathroom in the nastiest gas station would seem like the essence of floral nirvana compared to the smell inside the spacecraft after just a few weeks.

Not to mention sexual tension, personality conflict, stress, boredom etc.. etc..

I don't see this one being overcome until a spacecraft is built that offers enough room to allow some sense of personal space, or some sort of suspended animation system is developed, and frankly neither one is in the cards anytime soon.

My best guess, > 100 years and zillions and zillions of dollars in R&D, Process Development, and testing of a very large and expensive spacecraft. ( Developing a transporter... Priceless!)

It's not that I don't look forward to mankind going into space, it's just that I don't think it's possible for anything other than short duration, low earth orbit jaunts. And even if I'm way off on this, could we send a maned mission to orbit Saturn? No we couldn't so what does it really matter. Until we can solve some very basic "Human" issues, or are willing to spend obscene amounts of money on spacecraft we are doomed to stay put.

I'd be interested to hear what others here at /. think."

+ - What Geeky Things Must Be Done? 2

Submitted by John
John (666) writes "A few weeks ago, my friends were discussing "The Princess Bride", and most of the references went completely over my head — I've not seen it all the way through, nor read the book. Naturally, revealing this fact made these people look at me as if I'd just moved into town from under some rock. This led into a discussion of the things that most general geeks should be expected to know; for example, reciting the inscription on the One Ring, or (apparently) quoting "Princess Bride" on-demand. The suggestions we came up with ranged from personal things, like having one's movie/game library in an online database, to big, world-scoped things like contributing to an open-source project of your choosing. I'm curious to know what the general consensus is on the most obvious or biggest geek/nerd things that should be seen, done, or read/watched/heard."
Security

+ - Documenting Firewall Rulesets ?

Submitted by
An anonymous reader writes "I have a substantial amount of experience on "both sides of the firewall" and to date have used my knowledge and experience as wisely as possible. For much of the past decade I have been the primary administrator of an enterprise class firewall for a fairly large entity, having designed and built the current infrastructure from the initial installs. The firewall ruleset has grown quite large with our ever increasing dependence on internet connectivity and now supports several dozen DMZ resident systems as well as hundreds of site to site VPNs. We use an industry leader, enterprise class firewall, which allows central management of multiple enforcement points and does a nice job of self-documentation within the management console. I am now being asked by upper management to extract the detailed ruleset configuration from the safety of the management console and publish this information to an "internal document" which will be available to corporate resources other than the small team changed with firewall administration. It was offered that we can document the process of obtaining this information through the firewall management interface, but this was rejected and upper management is insisting that we publish every detail of the firewall ruleset to a shared directory on our network. Am I the only one that thinks this is a horrible idea and a potentially serious security issue? Can anyone provide any "best practices" documentation to support either side of the issue? I'm having real concerns with simply handing over the security information that I've spent many years protecting to those who may not understand the potential problems in publishing this data."

Lucas123 writes "Computerworld's Rich Ericson reviewed Sony's first all flash-based laptop, which carries a whopping $3,200 price tag. Ericson says the laptop runs incredibly fast, with an average data transfer rate of 33.6MB/sec and great battery life. But, the laptop is also limited to certain uses. While lending itself to travel, the small capacity of its hard drive doesn't make it a real competitor for a main PC workhorse. "While there's a lot to like [about the VAIO TZ191N notebook], there's only very limited uses for which I'd recommend this system. The best features — its size and the flash drive — are also its biggest limitations.""
