Slashdot Mirror

imamac writes with this excerpt from news out of Carleton University: "Atif Shamim, an electronics PhD student at Carleton University, has built a prototype that extends the battery life of portable gadgets such as the iPhone and BlackBerry, by getting rid of all the wires used to connect the electronic circuits with the antenna. ... The invention involves a packaging technique to connect the antenna with the circuits via a wireless connection between a micro-antenna embedded within the circuits on the chip. 'This has not been tried before — that the circuits are connected to the antenna wirelessly. They've been connected through wires and a bunch of other components. That's where the power gets lost,' Mr. Shamim said." The story's headline claims the breakthrough can extend battery life by up to 12 times, but that seems to be a misinterpretation of Shamim's claim that his method reduces the power required to operate the antenna by a factor of about 12; 3.3 mW down from 38 mW. The research paper (PDF) is available at the Microwave Journal. imamac adds, "Unlike many of the breakthroughs we read about here and elsewhere, this seems like it has a very high probability of market acceptance and actual implementation."

discards writes "I help run a student group at a Canadian University. For almost 15 years we've provided students with services such as web space, email, wireless internet on campus, cvs/svn, database access, mailing lists, etc., all using Linux and FOSS. In recent years, however, we have faced becoming obsolete. The university now provides wireless access, people get their email from other places such as Google, which also provides free svn access, web space, and so forth. Since we have a large amount of decent, usable hardware, as well as space, funding and a very fast internet connection, we are looking to possibly reform instead of just withering away and dying. We would like to ask Slashdot for ideas as to what we could do; preferably something that cultivates student research or provides an otherwise useful service to students, though all ideas are welcome."

An anonymous reader writes "The latest proposed solution to the fact humans suck at using passwords properly is to let people use digital objects, like mp3s, photos or videos instead. A file is hashed into a unique, secure string that acts as the real password. A paper on the idea was put forward in a recent Usenix conference on hot topics in security, and a Firefox extension that implements the idea is available too."

Pablo asks: "I have to do some programming in Windows (for school, not by choice). To say that I know jack-all about Windows programming would be flattering myself. I never do any programming under *NIX without my trusty copy of Stevens' 'Advanced Programming in the UNIX Environment' by my side. I'm wondering if there is an equivalent 'bible' reference book for Windows programming. Does anyone have any recommendations?"

So, for all you poor souls who lined up to give money to the borg: does it work? Any blue-screens yet? :) Update: 11/15 15:23 GMT by M : Okay, I'm sorry. That's green screen of death, not blue screen.

Anonymous Coward writes "Though often referred to as Earth's sister planet in terms of size and mass, Venus is now a totally different planet from Earth. Its temperature is high at 470C and atmospheric pressure at 100, and besides it has the characteristic atmosphere revolving at a very high speed (super rotation) and thick sulfuric acid clouds. Wrapping itself in an aura of mystery, Venus twinkles in the sky enticingly. At the Steering Committee for Space Science meeting held on May 10, the Venus probe mission was approved as an official ISAS project. http://www.isas.ac.jp/e/new/release/2001/06_03.htm l"

Forkenhoppen asks: "What is graphic tablet support like under Linux? I'm interested in getting a tablet for my computer for drawing/touching up art, and for using with the Gimp. What have people's past experiences been with different types of graphics tablets? What is the best one? Is there a low-cost tablet that works well under Linux? Are USB tablets supported? And most importantly, how many people actually use graphics tablets under Linux?"

Joshua Lamorie writes: "Rick Lehrbaum, the guy behind www.linuxdevices.com, and involved with the PC/104 Consortium has put together a group of heavy hitters from both the embedded world and the Linux world. The press release came out today, and lists the committee members. Also, on the Web site, there are archives of discussions about the creation of the ELC. This adds to the growing excitement about Linux in embedded systems over the past couple of months."

colonel writes "Corel Computer has released two new versions of the NetWinder Linux machine, a Group Server and a Rackmounted one aimed at ISPs. The RackMounted NetWinder lacks the multimedia features, but uses UW-SCSI instead of EIDE. Two can fit in 1.75" of 19" rack space. Hopefully, Corel will continue its tradition of donating hardware to the Centre for Creative Learning in Linux so we can see how well they "stack" up. " Heck, why stop there-I'd love to see how well it stacks up in my living room.
