Submission + - The Culture of Startup Mediocrity (twigged.net)

Frank Spinetti writes: "Back in early June, TechCrunch launched its 'Elevator Pitches', a key component in the popularization of the venture capitalist funding process. Securing funds for a startup is less and less the stuff of closed door meetings, suits and briefcases, it's fast becoming the everyman game. How far do sites like Elevator Pitches go in contributing to a culture of startup mediocrity? To what extent are web entrepreneurs hoodwinked by the prospect of 6-7 figure VC seed money? Have startups become a form of speculative Web currency?
This article takes TechCrunch Elevator Pitches as an example to explore some of these themes."

Submission + - Second Life OSS client victim of GPL violation

sithlord2 writes: "A while ago, Linden Labs,the creators of the 3D Virtual World "Second Life", released the sourcecode of their viewer under the GPLv2. This lead to various improvements in the SL-viewer.

Recently however, someone created an alternative viewer called "NakedLife", which is a derived version of the GPL viewer, that allows the user to see other avatars naked. While this is probably a violation of LL's TOS, the creator refuses to release the changes to the sourcecode.

Linden Labs has been made aware of the issue, but the discussion is still going on"

Submission + - The Best Mathematics Reference?

An anonymous reader writes: As my kid goes through school I'm going to have to clean out the cobwebs on some parts of the brain that haven't seen light in 20 years. Long division, calculus... algebra... etc. Can anyone recommend the best mathematics reference? Preferably electronic, but book form also considered. I'm actually hoping for something that starts with the basics and covers everything up to university level mathematics subjects, but I realise that might be a hard ask.

Submission + - Riemann Hypothesis -- The Other Sabot Drops

jim.shilliday writes: A recent Slashdot article ( http://science.slashdot.org/article.pl?sid=08/07/02/1418214 ) notes the publication of a preprint by Xian-Jin Li of Brigham Young University claiming to prove the Riemann Hypothesis. The proof cites and appears to be based in part on the work of the leading French theorist Alain Connes. A few hours ago, Connes posted a comment on his blog stating that the purported proof is so badly flawed that he stopped reading it: http://noncommutativegeometry.blogspot.com/2008/06/fun-day-two.html?showComment=1215071400000#c8876982000013974667 Connes is one of a relatively few people qualified to express an authoritative opinion. Li will have to respond.

Submission + - Next Quake to be Free and Run on your Browser (tfot.info)

Iddo Genuth writes: "The next version of Quake is going to be different, very different. According to id Software it will be free and will run on a web browser instead of a huge install on your computer. Did the guys at id Software lost their minds and decided to join Mother Teresa? probably not. The company is planing to introduce a substantial amount of advertisement into the game all that while drowning new players into the Quake world which would normally not buy the software. Is it a sharp move or another a huge potential failure — only time will tell. In the meantime, we are more interested in how Quake Live graphics will look..."

Submission + - Andrew Keen: Internet Anonymity Breeds Criminals

An anonymous reader writes: Renowned for his radical, anti-Internet views, Silicon Valley author, broadcaster, and entrepreneur Andrew Keen argues that Internet anonymity breeds faceless criminals. He insists that posting anonymously on social forums is fast becoming the norm and is the reason for inhumane consequences such as Megan Meier's death. Falling short of suggesting implementing tyrannical legislation against anonymous Internet users, Keen insists that those who do not want to reveal their true selves online have no business using the Internet.

Submission + - AMD Quad-GPU Performance revealed (pcper.com)

SizeWise writes: "If the idea of combining two different graphics cards for better PC gaming is appealing to you, then AMD's offering of up to four GPUs in a single system will definitely peak your interest. The new CrossFireX technology on display allows for any combination of up to four AMD RV670 GPUs including different cards such as the HD 3850 and the HD 3870 X2. Performance scaling is proving to be somewhat difficult for four GPUs even though three GPUs seem to be working very well on the handful of current titles that were tested. However, the flexibility of the CrossFireX technology over NVIDIA's SLI will allow many more gamers to see the benefits of multi-GPU technology."

Submission + - RIAA expert debunked by Prof. Pouwelse (blogspot.com)

NewYorkCountryLawyer writes: "Last year the Slashdot community "went medieval" on the testimony of the RIAA's "expert witness", Dr. Doug Jacobson, in UMG v. Lindor. Our friends at Groklaw did likewise. Now you can compare notes with a formally retained expert witness, Prof. Johan Pouwelse of Delft University — one of the world's foremost experts on the science of P2P file sharing and the very same Prof. Pouwelse who stopped the RIAA's Netherlands clone in its tracks back in 2005 — who has weighed in with his expert witness report characterizing Dr. Jacobson's work as "borderline incompetence". p2pnet calls the report a devastating blow to the RIAA's expert. (And in the shameless-plug department, if you enjoyed reading Prof. Pouwelse's report, and want to continue helping to get the truth out to judges and juries about the technology and science of the internet, please consider making a tax deductible contribution to the Expert Witness Defense Fund maintained by the Free Software Foundation, which provides funding for expert witnesses and other technical consultants who are assisting defendants in the RIAA cases)."

The Linux era ended in December 2007. Today all the Linux machines are back to running Windows.

Submission + - Gravity Lamp Grabs Green Prize (vt.edu)

eldavojohn writes: "A lamp powered by gravity has won the second prize at the Greener Gadgets Conference in NYC. From the article, "The light output will be 600-800 lumens — roughly equal to a 40-watt incandescent bulb over a period of four hours. To "turn on" the lamp, the user moves weights from the bottom to the top of the lamp. An hour glass-like mechanism is turned over and the weights are placed in the mass sled near the top of the lamp. The sled begins its gentle glide back down and, within a few seconds, the LEDs come on and light the lamp ... Moulton estimates that Gravia's mechanisms will last more than 200 years, if used eight hours a day, 365 days a year." The article contains links to the patents and the designer/inventor Clay Moulton's site."

Submission + - SPAM: Study derides feds telework efforts: $13.9B hole

coondoggie writes: "If all the government's eligible teleworkers worked from home, the Federal government could save $13.9 billion in commuting costs annually and eliminate 21.5 billion pounds of pollutants from the environment each year. The "Telework Eligibility Profile: Feds Fit the Bill" study is based on a survey of 664 Federal employees found that of those respondents, 96% of them should be teleworking, yet only 20% do. In fact, the Federal government telework deficit is equivalent to the gross domestic product of Jamaica, the study said. To offset the amount of CO2 emissions Feds disperse in the environment by commuting, we would need to plant 32 million trees a year... [spam URL stripped]"
