prostoalex writes "Researchers have developed a fuel cell that can be recharged with few milliliters of alcohol. MIT's Tech Review quotes the researchers claiming that those 'cells could eventually be used as a replacement for any rechargeable power source, including laptop and PDA batteries'. I suppose the scientists still have to explain all those bills from liquour store that say 'research material' on them."

nexex writes "The Seattle Post-Intelligencer's John Cook explores the current flood of money on wireless networking startups and if they could be heading towards another dotcom bubble. Interesting tidbits include, ;More than 60 Wi-Fi start-ups have raised more than $650 million in the past two years, according to VentureWire. Last quarter, there was more money invested into wireless technologies than networking and enterprise software.'" The article's got some good commentary on grassroots-founded tech trends vs. investment-backed tech trends, and tries to explain why wi-fi has caught on so well.

A not-so Anonymous Coward asks: "After being on a rather slow PC for some time now, I have finally made the jump to a 1GHz+ PC. Being fairly new at having a rather fast PC, I am not very sure where to go for system performance tweaking. A few friends pointed me to Monroe World and TweakXP. Both are pretty good sites, however I find that my system still doesn't perform as well as it should when running a benchmarking test like 3dMark 2003. My score is just under 2000. I know people who have slower systems than mine and get a score around 5000. So I am turning to the Slashdot community to ask: Where do you go to find out the latest and greatest hardware and system tweaks? Do you have your own tweaks, and if you do would you mind sharing your secret tweaking tips?"

Jasin Natael asks: "What PDA's/Smartphones, etc. support complex languages in addition to more 'standard' languages? I'm a student of Japanese and am looking for a new PDA or smartphone that operates in English, but supports complex character sets. Input is a plus, but it's really needed for Contacts, Notes, Websites, and incoming E-Mail at a minimum. Would it be easy to add support to a Linux PDA (Zaurus) or Pocket PC for this? What about right-to-left languages, like Hebrew and Arabic?"

Sarreq Teryx asks: "I'm looking to buy a new case for my system, to fit in a particular space (20¼" tall x 11" wide), I've found plenty that fit the height (I personally like the Lian-Li PC-6089A out of that bunch), but all the cases I've seen are either the too-too narrow 7½" to 8¼" wide consumer tower cases (that Lian-Li included), or the super wide 13" to 20" wide server cases (which tend to be on the unbearably ugly side), both of which are the wrong width.Does anyone happen to know if any PC case company makes cases that are ~20" tall x ~10¾" wide, or of any company makes custom cases from the plate metal up? I've never done any metal working, so if I were to make one myself, it'd end up being made of wood, and I don't particularly like that idea."

zambuka asks: "Recently I was asked about pricing and availability of wireless microphones. What is needed are 15 wireless microphones, appropriate base units and the ability to record the signal from each microphone on a separate track. A session will last about 2 hours and the results need to be recorded to a CD. I have priced this at about $25000AUS probably less with bulk rates for the mikes and transmitters but still a big cost and not particularly portable for the base and recording units. The question I have regards alternatives. I have thought about using MiniDisc recorders, Nomad and Muvo. These are a much cheaper alternative and will suffice but require a major effort to transfer everything back to a PC and burn to a CD. I was also looking at wireless networks: 802.11a/b and Bluetooth and thought about how much cheaper and more suited to my needs this technology seems to be. Can these wireless systems cope with the constant throughput I need for this? And, is it possible (preferably with off the shelf components) to set up a wireless VOIP or similar network capable of dealing with this quantity of audio and recording the signals separately. Links to the tech would be welcome. Anyone living in Canberra who would like to take a shot at setting something like this up can feel free to contact me."

Nvidia Lacky writes "Ran across a new article from LinuxHardware.org that goes through NVIDIA's new driver release and also takes a first look at a CineFX-based NVIDIA card, the Quadro FX under Linux. Should be a good read for those that have been frustrated with Linux drivers in the past or that are looking to get a new workstation video card."

freitasm writes "30 years ago, 3 April 1973, Dr Martin Cooper placed the first cellular phone call, to a rival scientist. The NY Times has an article about the "crime scene". Dr Cooper now works as CEO of Arraycom." There's also a story on siliconvalley.com.

Rob Flickenger writes "I for one am sick and tired of all of the work it takes to build out wireless community networks. Evidently, so was the Linksys Community Network: a Real Network project for the masses. It's about time somebody did something to bring Wi-Fi to the People."

gordlea asks: "Has anyone ever had a gadget that has acted in a seemingly possessed manner, or that seemed to have a personality of it's own? We once owned a Panasonic fax/phone/answering machine. This thing was crazy, it would randomly call up people who had called our place recently and play back messages other people had left for us. Occasionally it would even record our conversations and play them back to people who called when we weren't around! So do you have any good anecdotes along similar lines? I'm looking forward to hearing them!"

Tadau asks: "Knowing not much of the low-level and molecular aspects of a hard drive platter, I'm wondering if it is possible to cause a weight change/imbalance on a hard drive platter by say writing solid 1's to approximately 1/2 of a side of the platter? If there is a weight change, then could that attribute to drive vibrations by an ever-so-slightly unbalanced platter, which may result in an eventual drive failure?"

bertok asks: "I have several spindles of CD-Rs of various brands that I use at home and work, and some of them have a very strong almond odour when opened. Does anyone know what causes that? I know that Hydrogen Cyanide has a distinctive almond odour, but so does a range of other organic chemicals. Can any Slashdot readers with a chemistry background enlighten us as to the possible source of the smell?"

(startx) writes "I don't know how long this has been the case, but with the latest NVidia driver update comes a new installation method, which unifies the installation process almong all Linux distributions. Just for kicks I re-read the licence, and it has a new section labeled "2.1.2 Linux Exception" Basically GNU/Linux users are now free to redistribute the driver file. Not only this, but the FAQ section of the README file says you can redistribute in whatever form necessary, stating distributions are welcome to include it as a package as well. Woohoo!"

bilsaysthis asks: "Bill Kearney poses a really interesting question, one which I've been puzzled by for a while too: 'What's with prices on LCD displays? On one hand a laptop can be had with UXGA resolution display for $1000. Try buying that display alone and you'll find it's also around $1000. Then there's how much they're gouging for the same resolution in an LCD television.'" Sadly enough, as much as I want one of these for my wall, the market is willing to bear these prices. How long will it be before this hardware becomes affordable?

williwilli asks: "Musicians face a multitude of challenges in this day and age, yet there are a number of musicians also trying to work towards the future. One constant challenge in almost any profession in money. With CPU's continuing to advance at a rapid rate, many musicians are finding computer-based software synthesis to be much more cost effective than traditional hardware synthesizers. While some musicians are using portable systems, the lack of expandibility limits the systems capabilities in terms of synthesis, multitrack recording, etc. While one could always throw more computers at the problem, many users will no doubt find a rackmount system provides much more capability and expandibility. As such, what insights might the Slashdot crowd be able to provide towards building your own rack? Is shockmounting necessary? Are parts readily available, or are there any 'open-source' CAD files out there? Are there music-specific materials, designs, or tips to recommend or avoid?" Would rackmounts for a mobile musician really differ so greatly from rackmounts made for a small server cluster?

linuxwrangler writes "In preparation for the national do not call registry, California's Attorney General has established a pre-registration site for California residents. Based on how slow the site already is, this is going to be one popular program. The AG's announcement also mentions that they have shut down some scam sites offering do-not-call registration so caveat emptor. Are any other states offering similar services?"

An anonymous reader writes "The BBC has a story about a company who has developed an LCD screen that can produce sound as well. They claim that the sound quality is quite good, and compare it to average multimedia computer speakers. Also NEC is making and selling computers that use this technology in Japan. Hardware integration like this should make for some interesting appliances in the next few decades."
