Slashdot Mirror

An anonymous reader quotes a report from Ars Technica: The silicon-based cells that make up a solar panel have a theoretical efficiency limit of 29 percent, but so far that number has proven elusive. Practical efficiency rates in the low-20-percent range have been considered very good for commercial solar panels. But researchers with Japanese chemical manufacturer Kaneka Corporation have built a solar cell with a photo conversion rate of 26.3 percent, breaking the previous record of 25.6 percent. Although it's just a 2.7 percent increase in efficiency, improvements in commercially viable solar cell technology are increasingly hard-won. Not only that, but the researchers noted in their paper that after they submitted their article to Nature Energy, they were able to further optimize their solar cell to achieve 26.6 percent efficiency. That result has been recognized by the National Renewable Energy Lab (NREL). In the Nature Energy paper, the researchers described building a 180.4 cm2 cell using high-quality thin-film heterojunction (HJ) -- that is, layering silicon within the cell to minimize band gaps where electron states can't exist. Controlling heterojunctions is a known technique among solar cell builders -- Panasonic uses it and will likely incorporate it into cells built for Tesla at the Solar City plant in Buffalo, and Kaneka has its own proprietary heterojunction techniques. For this record-breaking solar cell, the Kaneka researchers also placed low-resistance electrodes toward the rear of the cell, which maximized the number of photons that collected inside the cell from the front. And, as is common on many solar cells, they coated the front of the cell with a layer of amorphous silicon and an anti-reflective layer to protect the cell's components and collect photons more efficiently.

An anonymous reader writes "I have been working on an HTML5 app for Panasonic VIERA TVs, specifically a client for the Plex Media Server. After paying $129 for the developer program, version 1.0 was submitted for inclusion in their VIERA Connect marketplace several weeks ago. After a few requested tweaks, they inquired about how the client communicated with the Plex Server. As many/most web developers do, I used jQuery and its $.ajax call (which is just a wrapper for XMLHttpRequest()). They insisted this was not standard Javascript, and after several communications with them, they replied back with "A workaround like this is considered a hack.". I'm stunned that anyone familiar with HTML would consider jQuery a hack. I've been patient in attempting to explain how jQuery works, but I am getting nowhere. Any thoughts on how I can better explain jQuery to an app reviewer? Yes, I know I can write my app without any Javascript library, but I am really hoping avoid that."

WeeBit asks: "I saw a news article on why you should buy Plasma instead of LCD TV's. It just sparked my interest. Flat panel TV's have the market now, and our analog TV's are on their way out. I am sure many will be thinking of purchasing their new flat panel within the next couple years. Have you given this any thought? Panasonic, has been pushing ads that sell the consumer on the plasma TV's over the LCD's. Is this a good argument, or is it just hype? Which do you prefer Plasma or LCD? Why?"

marksilverman writes "The New York Times is reporting that Panasonic will start selling (Biometric scan required to prove your value as a human being) next generation Oxyride batteries soon. They last twice as long as premium alkaline batteries, they deliver more power, and they're cheaper. They're already popular in Japan. The downside? They have a shorter life in a "rundown test" where you put the batteries in and leave the power on until they're drained. In real-world scenarios (like how many digital pictures you can take) they do really well."

pmadden asks: "I'll be building a house this summer (standard straw bale construction, earth plaster, the whole low-tech gig). Naturally, I'll be putting gobs of ethernet in the walls, with drops to the rooms, on the roof, and so on. I'll add wireless too, once it's secure enough to keep all of you out. What gadgets should I plan for, so that I don't have to do a major retrofit? I'll have cables for TPZ cameras, for when they get super-cheap. We'll leave niches for putting in routers and stuff like that. What else? What cool thing will be cheap in a couple of years, leading my wife to ask, 'why didn't you plan for that'? Any recommendations for good Christmas light control systems, and so on?"

securitas writes "The New York Times Technology has an excellent feature by Ken Belson about the coming battle over the next-generation DVD format that consumer electronics and technology giants are already preparing for. The article covers the (high-definition) HD DVD group, led by Toshiba and NEC, and the Blu-ray Group, led by Sony and Matsushita (Panasonic/JVC). Mass production is expected to begin in 2005, but both sides are expected to show prototypes and aggresively pursue partners at the Consumer Electronics Show (CES) in Las Vegas next week. Add to the mix a nine-company Chinese faction that says it will develop its own DVD format because - fearing their technology could be used by Chinese rivals - the Japanese manufacturers haven't shared much information, even within the DVD Forum. Finally, Disney, Microsoft, IBM and Intel have yet to weigh in. The worst thing that could happen would be another Betamax/VHS-type war. In that case, 'Everyone is a loser, particularly Hollywood studios, the retailer community and, most importantly, the consumer,' says Warren N. Lieberfarb, developer of the original DVD format."

securitas writes: "Reuters reports that Nokia is considering a takeover of Psion (mirror at Forbes), to gain control of the Symbian operating system. Psion is the second largest shareholder in Symbian with a 31.1 percent stake. Nokia holds 32.2 percent. The move is seen as a tactic to fight off Microsoft and dominate the lucrative and growing mobile phone software market. Symbian is currently owned by Ericsson, Nokia, Panasonic, Psion, Samsung Electronics, Siemens and Sony Ericsson. The report originates in the London newspaper, Business. What does this mean for the Symbian OS, which is currently an open OS?"

securitas writes "The New York Times is carrying a Reuters story about Linux as the software of choice for consumer electronics. At the world's largest consumer electronics show, the IFA trade fair 'the first Linux products are already on show and more will come soon, companies said.' The reason? Linux is freely available, widely embraced and profit margins in the consumer electronics business are one or two percent at best. The math is simple. The industry push comes from the members of the Consumer Electronics Linux Forum (CELF), that includes Sony, Philips, Matsushita/Panasonic, Hitachi, Sharp, Samsung, NEC, IBM, LG, Thomson/RCA and Toshiba. The CELF was previously discussed on Slashdot. Mirrors at Silicon.com and CNet News."

worm eater asks: "My office is thinking about purchasing a multi-function printer/copier (MFP). We are currently looking at the Panasonic Workio 3510, but there is a surprising lack of reviews on the internet (there is one at ePinions). Has anyone had any experience with this model (which went on sale last month) or other similar machines? We are looking for a good B&W copier / laser printer capable of connecting to our LAN. The ability to interface with Exchange and send internet faxes would be nice, but not essential. As with pretty much any copier, we will need high quality support. Thanks in advance, Slashdot."

WCityMike writes "Major Shawn Weed, an intelligence planner with the Third Infantry Division, eschewed his Panasonic Toughbook because it wasn't fast enough in processing giant satellite and reconnaissance images. He put in a requisition for and received a PowerBook G4, the only Apple currently being used in the entire Middle East theater. 'Frankly, lives are in the balance here, so the quicker I can get stuff done accurately, the better,' Weed says."

Raetsel writes "Caught a commercial the other day hawking the device I've been waiting for. TIVO is a great idea, but what if you want to keep something more permanently? Enter the Panasonic DMR-series. The top-of-the-line DMR-HS2 ($1000 US) has a 40 GB hard drive, offers "Time Slip Playback" (TIVO's "pause live TV" function), and allows you to move shows off the hard drive onto DVD. Heck, you can even record straight to DVD-R or DVD-RAM discs (which is what the $700 DMR-E30(K/S) does). There's also a IEEE-1394 input, so you can record from sources that have a FireWire output. Oh, yeah... it's a progressive-scan DVD player, too."

saitouhajime writes: "Matsushita is reporting that they've developed a method of storing 100 Gigabytes onto a standard sized dvd. Articles can be found here(1) and here(2)." 100GB on a disk would be a nice way to store backups -- but since the DVD consortium hasn't made any promises, this format may remain just a demo technology forever.

Dr. Zowie asks: "How should one choose a router for a home LAN? We just added a few hosts on our home ethernet, which is connected via DSL. There are an amazing number of new entries into the market for routers and even stand-alone firewalls. NetGear, Linksys, SMC, and even Panasonic all have boxen in the $99-$300 range, each of which will do some combination of NAT, routing, source-IP filtering, port filtering, and content filtering."

"It's not at all obvious from the packaging, the web sites, or the drool-proof pamphlets in the boxes which routers will do what. For example, we'd like to pass through packets for our two server machines, and use NAT/DHCP on a third address for the rest of the LAN. Nearly all the boxes advertise that they can do NAT routing, but many don't support NAT and static-IP routing simultaneously.

Die-hards will insist that one should run a standalone box with dual ethernet cards and the appropriate routing goodies -- but these standalone boxes, at 5-15 watts and a couple hundred bucks, seem like comparatively hassle-free solution. Which one do you use?"

Lets start this off with some homework: we were nominated for a 2000 Webby in Community. Please go vote for us (requires annoying login, but please do it anyway! I want a crappy little trophy!) Now with the 'biz outta the way, brainsik pointed us to the Brainshaker: a headmounted subwoofer that looks like it would make Quake a bit to real. Plastik noted a web filter guaranteed to offend the conservative and humorless. But it makes reading Slashdot damn entertaining. And if you're interesting in violating most religions, vkulkarn found an "Escort" who apparently reads Slashdot (will she go out with CowboyNeal?) Speaking of religion, Zippy noted that I am apparently a prophet in the Church of The Enlightenment , along with Jay Stile of Stileproject . Illiad, from Userfriendly.org is a bard. webword sent us CalculusGirls.com which combines 2 of the many things I don't understand. Andy Lester noted that Brunching Shuttlecocks has a book on "Fuzzy Logic Functions", in the style of O'Reilly. yek401 noted that his english professor builds barbie doll cyborgs: god bless tenure ;) Trenchcoat Steve warned us about Moon Land Registry which claims to be selling land on the moon for $10/acre: you even get a deed and mineral rights... and it might be legal! Gravey noted that their are two new Reboot movies going into production. For you conspiracy theorists, backtick noted that everyone's favorite software monopoly might be getting into the furniture biz along with Lazyboy. SgtPepper pointed us to RFC 2795 which "describes a protocol suite which supports an infinite number of monkeys that sit at an infinite number of typewriters" ucsimon noted that LegoLand in California just gota liquor license. Mind you after a few shots of vodka, finding a 2x2 blue block takes a lot longer. Let's wrap up with jyuter's note that Comedy Central has vid clips of the south park kids doing Python's parrot sketch in Quicktime or Real.

Element5 writes "Netcenter's Tech News reports that Pioneer will be selling the first DVD players (not DVD-ROM drives) to be able to record up to six hours of programming to rewritable discs. Check out the story. Pricing is high, as expected: $2399 US for the unit, $28.79 per disc. " And watch closely, as the film industry gets a panicked look in their eyes. Update: 11/27 08:47 by H : Thanks to Jim Choate for the story that Panasonic has introduced DVD-RAM for only 700$US.

snack writes "Hey guys, I was surfing around, and somehow I came across Panasonic Tough Book. These things look uber cool, magnesium casings and all. They've also got shock resistant lcd's and hard drives. Water proof, and dust proof. Very very kick ass." Okay. Finally I'm gonna jump on the Slashdot "I gotta have one of these!" bandwagon. (My tongue is hanging out as I type.) Update: Yes, we know hardened laptops aren't new, but this is an exceptionally slim, light, and cute one. -Roblimo

redbeard writes "The NYTimes (requires free login) has an interesting write up on "ruggedized" laptops, these things can withstand tornados, being run over by trucks and being submerged in water, among other things. Panasonic is planing on a scaled-down line for consumer use, kind of like the Hummer vs. HUMVEE." If it lasts more than 6 mos in my hands, I consider it rugged...

When I put out my call for Geek Christmas Gift ideas, I had no idea what I was in for. But after the storm of email that followed was washed away, I was left with a list of toys that any geek would be excited to give or get this year for whatever holiday it is you celebrate this time of year. Hit the link below and read the list if you're curious. Random Stuff There were a few things that were suggested, that, well, I bet Santa won't come through for them. Hemos asks for Nanites. Thats all he wants. Nanites. Somebody smack him. Nima Negahban says "I would like the beowolf cluster avalon for christmas, dont worry about it fitting it under the tree. " david yates wrote in and simply said "Half naked Princess Leia ,as Jabba's prisoner, action figure." I'm sure his mother is proud. He can have the Action Figure, I want 1976 Carrie Fisher. Games Everyone and their brother wrote in to say that Nintendo 64's and Playstations are great. And the game of choice is definitely Zelda 64. I second that motion. I suggested it to my dad as a Christmas Present. Terrible idea- now I gotta wait until xmas to find out if he got it, and if he *didn't* I gotta buy in on Dec 26. Hard as hell to find. Folks suggested other things like the original Kings Quest or Leisure Suit Larry. Prince of Persia. Commander Keen. Ultima. All those games that aren't around any more, but with their original packaging. Finding a 5.25" drive to play them with might be a tad tricky tho. Clothing It's a well known fact that its better to be clothed at least part of the time. And no self respecting geek should be without a vast array of appropriately political t-shirts to pad out your closet full of suits, jackets, and ties (cough). Daniel suggested checking out the Free BSD Mall for BSD clothing. Jonathan Moore suggested the ever popular KMFMS t-shirts for your local microsoft hater. If thats a bit to exotic for you, how about the classic that Doug Boettcher sent us: the Hack Naked shirt. Since we're mentioning all these t-shirts, we ought to mention that CopyLeft has several shirts including my Don't Fear the Penguins ones, and Slashdot ones too. Software Several folks wrote in to say that they were buying Linux CDs from any of the various places that sell them, and giving them away to the needy. I tend towards Linux Central, and in addition to them Cheap Bytes OpenBsd.org and The Linux Mall were all suggested as places where you can buy the stuff we like. Hardware By far the largest catagory for gift ideas was of course Hardware:The Gift that Costs to much. Of course, anyone would want a a Palm III- it's hard to think of a better stocking stuffer. And besides, they're practically money in the bank now that you can use them to collect automobiles of the rich and famous. But if you've already got a Pilot, James A. Hillyerd suggests a GoType keyboard as the perfect accessory. If the pilot isn't your bag, but you want to read on the road, Mahlen Morris suggested A Rocket E-Book which is basically a tablet computer that is designed to replace books You can get them here. And apparently they have some sort of deal with Barnes & Nobles so you can get content to read on it. They're pretty sweet looking- someday we'll have a wireless version with net access, then we can forget paper. But for now, this'll do.

Have trouble remembering passwords? Digital Persona sells sweet hardware that that you can use to do finger print identification. Suggested by Andrew Lepisto. The pdQ was suggested by Adam D. McKenna. Its a cel phone with an integrated Pilot. Another fairly common suggestion for geek gifts was cel service from your local provider, and a cel modem for the laptop equipped gift getter. Sean McPherson suggested a Kodak DC210+ digital camera. Saves big bucks on film, and is supposed to be supported by SANE. I'm actually planning on getting a Digital Camera before the upcoming string of conferences, and I'll probably look at this one (unless Santa already has one in his bag for me, although at $400 a pop, I highly doubt it) Steven McDonald suggests that we look at DVD RAM Drives as a new huge backup device for storing your MP3s and Porn. Oh, and legit data too.

Mike Miller sent us several suggestions including the Happy Hacking Keyboard. I played with one at ALS- they're not bad. Just as cool are the new Color Gamesboys. I suppose tetris wouldn't be vastly improved by color, but its still pretty sweet. For those with a hugeass budget, How about your very own Alpha Cluster? Obviously Jakob is a lot more hopeful for Saint Nick than I am this year *grin*. How about a vt320 Terminal? Daniel Morrison suggested it, and I think it sounds pretty cool. I had a terminal attached to one of my Linux boxes for awhile. I Let it tail log files and stuff. Kinda fun for reading documentation and stuff too. Can't afford a Multi-Head X-Server, video card, and spare monitor anyway. Plus you can run them into another room and check your email from your kitchen/dining room/bathroom.

Matthew J. Allen sent us a pricey one, but its oh so sweet: Remember those Huge Flat LCD Screens from SGI? I sure do. I wake up after erotic dreams about them. (SUBLIMINAL MESSAGE:Hey SGI: Give Rob one of those things for banner ads. You've got a spare one just sitting around, right?). Matthew also suggested an Iomega Clik Drive if you're on a more reasonable budget. Those things do look pretty sweet. Do cables piss you off? How about the gift of a tangle free workspace? Scott Donovan sent us a link to Cordless Mice and Keyboards from Logitech that will free you up for spinning on your swivel chair really fast until you fall over from getting dizzy instead of getting tangled up in your keyboard cable.

Toys By far the single most suggested toy of all was the Lego Mindstorms. The robotic legos are quite possibly the coolest toy in the history of toys. They aren't cheap, but they are oh so sweet. Else you could consider X-Files Action Figures suggested by E. Waugh. Home Entertainment and Audio Gear The Panasonic Portable DVD Theater was sent in by Joel Telling. Its a tiny portable DVD player obviously designed to make me froth at the mouth like a rabid dog. Several folks wrote in to suggest something I would like, but I wouldn't want to froth on. The Empeg Car CD Player. We've mentioned this before, and although they won't be ready for christmas, they are pretty amazing. 2.1 gigs of MP3s in a car stereo. They need a 9 gig version mounted in a home stereo component too.

Jon Jones (is that a real name? *grin*) wrote in to send a link to ADB I/O which you can use to automate your home for the ultimate in comfort and/or laziness. For the true audio junkie, how about the THX Speakers sent in by Chad R. Henry. Sure, they cost more than my car, but I bet they sound amazing. If you're on a more modest budget Cambridge SoundWorks has some slightly more reasonably priced speakers that I'm told sound awesome. Andrew Hobgood suggests checking out Panasonic SJ-MJ70 MiniDisc Player (portable). Pretty sweet if you aren't willing to chance it on the Diamond Rio (which was also one of the most common suggestions). Frankly any geek should be excited to get either. Rob Sheehy pointed out that Philips has 42 inch widescreen flat TVs that you could hang on your wall if you happen to be rich and wanna watch letterbox movies. This one has a VGA input too.

Random Terry A. Braun suggests that geeks need to get into making our own beer. Sounds like a great idea to me, although I tend to screw up toast. But if you're man enough to try it, you can get Your Own Grain Mill. Alan Mathews wrote in to suggest a A dilbert M&M dispensor McPhee's has some strange stuff, including a Punching Nun suggested by Glen Lipka Tom Berger suggested A VI Command Set Mug STriker RedWolf sent us a link to a chocolate bar shaped like a Pentuim II Chip.

Jason Grundy suggests the $6 card game Kill Dr. Lucky and a Card both from the aptly titled Cheapass.com. Rob Pelkey sent in a pair of gift ideas that are a world apart. The first is An Authentic Moon Rock and the second is a Jesse Ventura T-Shirt or Bumper Sticker. One is probably worth a little more than the other. The concept kitchen has this wierd Finger Stylus Thingee that you can use instead of a pen for some pen machines. Kinda wacky. Sent to us by Wyatt Earp.

Justin Higgins suggests that geeks should all own a copy of the Star Wars Radio Drama. Sure, it costs almost a hundred bucks, but at 15 CDs, it balances out to almost be a bargain. They ought to package it on 1 CD full of MP3s, throw a copy of the script on the disc and sell it for $20. I'd never heard of the Leatherman Wave before, but several folks emailed me to say they are cool. And then I noticed that they were actually advertising here. Shows how much attention I pay to who advertises on my own site I guess. But still several people raved about them, claiming that they're ideal for mucking around inside computer cases with. And Traci Earl sent a link to a site that makes nice Leather Cases for them.

Do you think stuffed animals are stupid? Well how about a Stuffed Plush Space Shuttle? Dave Brunberg sent us that gem. Stirling Westrup sent in a link to something called the Hoberman Sphere which basically is a crazily designed sphere thingee that expands from 9.5" to 30". Crazy looking. If you're looking for something caffienated that you can put in your mouth, several folks reminded us about caffienated penguin mints.

Wrap Up Well this was fun guys. Spending hours looking at crazy things that I can't afford has convinced me to take up cracking banks as an evening hobby. But what is quite obvious is that 1998 is a good year to be a geek. And maybe in 1999 Hemos can have his nanites. Nah.

And lastly, with all the commercial hub bub that tends to go on during this season, don't forget the true meaning of Christmas: Ham.
