DIY USB Servo-Guided Water Gun 66

An anonymous reader writes "What better way is there to learn something than by making your own DIY gadget? Here's a new video showing how to use a common hobby servo, in conjunction with a small water pump, to create a USB controlled water gun! You can use your keyboard to aim and fire at an unsuspecting passerby. Both fun and educational, this project looks like a great DIY weekend project for any IT guy, wanting to make sure people think twice before asking a stupid question!"

Submission + - The Internet changes the music business (blogspot.com)

Krishna Dagli writes: "After reading this slashdot story,the blog entry here makes quite good observation on how music industry should realign.
From the blog entry "Many experiments are afoot on rethinking business models in this age of the Internet. The essential opportunity lies in utilising the very computer technology — which has obsoleted the record / CD business — by linking up the ultimate artist to the ultimate consumer, so as to eliminate the overhead of various middlemen. Byrne writes that a large portion of the cost of a CD is in overheads; the payments by the buyer of the CD mostly don't reach the artist. The 15% of the overhead that's spent on marketing/promotion is in the interest of the artist, insofar as it is about raising publicity and awareness. And yet, a key change of the electronic world is that friends pass on music to friends, giving a powerful word-of-mouth phenomenon through which awareness can be increased. It is different from the marketing blitzkrieg of pop music of old, but that doesn't mean it's non-existent.""


Submission + - eBay and Tiffany lawsuit (nytimes.com)

Krishna Dagli writes: "The outcome of this lawsuit can affect a lot of online (and probably offline businesses), it can even change how
online auction houses conduct their business online.

From the article "In a weeklong bench trial in Federal District Court in Manhattan that ended last Tuesday, lawyers for Tiffany & Company argued that the online auction house was far more than that: it is a distribution network that enables the trading of counterfeit Tiffany items."

Submission + - Japan's melody roads play music as you drive (guardian.co.uk)

Krishna Dagli writes: "What would be the sound like inside the vehicle? Does one also feel small speed bumps?

The concept works by using grooves, which are cut at very specific intervals in the road surface. Just as travelling over small speed bumps or road markings can emit a rumbling tone throughout a vehicle, the melody road uses the spaces between to create different notes."


Submission + - A small victory for the EFF: EFF, Telcos and NSA (arstechnica.com)

Krishna Dagli writes: "Well this is a good news for the EFF, but will the case move on to discovery? Will telcos cooperate for their own benefit?

From the article link:
"In a victory for the EFF, Judge Vaughn Walker ruled today that AT&T, Verizon, Cingular (now part of AT&T), Sprint, and BellSouth (also part of AT&T now) must all maintain any data or papers related to the NSA spying case that Walker is overseeing in California. The EFF had requested the ruling out of concern that documents would be destroyed as part of routine data deletion practices before the case could even progress to discovery.""


Submission + - Real Spiderman coming to a ceiling near you (networkworld.com) 1

coondoggie writes: "Italian researchers today said they have formulated a substance that mimics spider and Gecko sticking power that they claim are strong enough to suspend a person's full body weight against a wall or on a ceiling. University of California, Berkeley researchers are also developing sticky technology they say will support heavy weight on smooth surfaces. First, Italian researcher Nicola Pugno, an engineer and physicist at Polytechnic of Turin, Italy said he has come up with formulas for using carbon nanotubes to make superadhesive gloves and boots that could be used in the future to create a super sticky suit ala Spiderman. He said the same technology could be used to build invisible cables that could act as super-strong cobwebs. http://www.networkworld.com/community/node/18865"

Submission + - Parallel computing in Python

Krishna Dagli writes: "Is it really possible to write high performance/parallel code without knowing C/Fortran and MPI? This link about Star P product suggests that existing Python code will not require reprogramming and Python users don't have to become parallel programming experts to take advantage of parallel processing architectures."

Journal Journal: Stop advertise SCO

As you all know, positive advertising is good, but negative is just better. I can't understand why there are still articles related to SCO mafia even the content is negative. They are idiotic racketeers and any mention about them, only helps to make their thing done. As I look in the textarea in the journal entry post form, IBM is in the spellchecker dictionary and SCO is underlined as an unknown word. Forget them please. Paul Graham wrote nice article

Submission + - RSA 2007: Botnet Live Presentation now Online

An anonymous reader writes: At the recent RSA 2007 conference, one of the few talks given that received any sort of coverage was one I was lucky enough to attend, "Botnet Live" — where the researchers involved (Chris Boyd, and Wayne Porter) talked about how they used methods other than simply looking at the Botnet data to catch the bad guys. The idea was, by looking at all the "real-world" evidence surrounding the botnet, and continuing to "track" it after the work on the Botnet itself had been handed over to the authorities, more data could be generated in terms of profiling the people behind the hacking than if they'd just kept to the technical side of things. In the talk, they focused on two examples — one involving a Botnet where a custom built PERL script was used to suck down personal data from third party payment systems, and the other involving a group of Hackers based in the Middle-East that used Rootkit technology, fake BitTorrent clients and modified IRC clients to push their radical ideologies. The full presentation is now online, and I recommend anyone with an interest in Botnets (and the people behind them) take time to watch / listen to the full thing.
