  1. Ultra-Dense Optical Storage on One Photon

    Hardware · Storage · · posted by CowboyNeal · from the smart-particles dept. · 139 comments
    Andreaskem submitted this story about researchers being able to encode an image into a photon and to later retrieve it intact. From the article: "It's analogous to the difference between snapping a picture with a single pixel and doing it with a camera — this is like a 6-megapixel camera... You can have a tremendous amount of information in a pulse of light, but normally if you try to buffer it, you can lose much of that information... We're showing it's possible to pull out an enormous amount of information with an extremely high signal-to-noise ratio even with very low light levels."

  2. Wireless Community Summit Tackles Digital Divide

    Hardware · Wireless · · posted by simoniker · from the over-the-ether dept. · 69 comments
    jens writes "More than 150 participants (including Matt Westervelt, Seattle Wireless) from 30 countries will discuss on how to overcome the digital divide building wireless community networks. The freifunk.net summer convention 2004 takes place from 3rd to 10th September in Djursland, Denmark. The convention's location is well chosen -- DjurslandS.net (in Danish) itself is probably the most ambitious wireless community network of the world. About 200 volunteers installed more than 100 masts on the remote area's 32 000 sq mi. Using the wireless standards 802.11a/b/g about 1'500 households enjoy a symmetric 1-2 MBit internet connection via WI-FI (the WI-FI network has 8 direct uplinks to the danish backbone and several DSL fallbacks). The wireless4development track organized by wire.less.dk will show other projects how to follow the DjurslandS.net example. The convention starts off with a 3 day program including VoIP, development for the meshcube and antenna building and finishes off with a 5 day hands-on workshop."

  3. Primers for Semiconductor Physics?

    Ask · Education · · posted by Cliff · from the quickly-brushing-up-on-those-rusty-skills dept. · 36 comments
    mactom asks: "Hello, I am a physics engineer with a background in lasers (non semiconductor), but during the last years I have slipped into a job in semiconductor technology development. We define the manufacturing technology and how the transistors, diodes and other devices are to be designed and manufactured on the silicon level. First I did lithography only but now I am involved in layout and design of devices and in the whole technology development. After all of this, I've discovered that I have some serious gaps in my semiconductor physics understanding! I need some suggestions for books, tutorials or even seminars (in Europe/Germany) about semiconductor physics. Yes, I have some books already, but I always have the feeling that I miss something important when I do some self studying. So, I need some 'semiconductor for dummies' books or seminars.Any suggestions?"

  4. Slashback: Regionalism, Rivalry, Zensur

    Slashback · · posted by ryuzaki0 · from the fountain-city-big-lots dept. · 261 comments
    Slashback with more (below) on: censorship in germany, Xbox gushing, *nix-ish Window managers on That Darn Operating System, and more. Enjoy!

    Even the Gates family probably hates being ripped off by region coding. jmcmurry writes: "I just tried out my daughters Winnie The Pooh from Poland, which can only be played (until today) on my Mac Cube running OS X (I did the region free crack when running OS 9). I own an Xbox with DVD player and thought, hey wouldnt hurt to try it out, since I was in the market to buy a Region Free DVD player (which can cost $400 an up) I plugged everything in, put the DVD in, and lo and behold, it plays the DVD from Poland (region code 2) This makes up for the cost of the Xbox ..."

    Nein! Nein! Speaking of things that do (or don't) work by region, several readers submitted information which indicates the pooh-poohing of alleged censorship-by-DNS manipulation in Germany's state of Nordrhein-Westfalen was premature. It turns out that some interesting redirects which seemed to be a technical error or a misguided proof-of-concept, and which were quickly turned off, were reinstated shortly thereafter.

    Thorsten Hornung was among the several to write on this topic. "Meanwhile ISIS has reblocked the sites, as Heise online reported (German!) due to pressure from the president of the local Government Mr. Büssow.

    The local government of Düsseldorf which is responible for media services in North Rhine-Westphalia has posted a statement on its site (German) about the initial lift of the blockade saying that it believes the censoring meassures have been lifted due to complaints by users. Much worse is that furthermore public accuse people complaining about the censorship to be Right Extremists: 'The local government believes, due to the content of many emails it received today, that they [People Complaining] are users of Right Extremist Internet Content.'

    The German Constitution (Grundgesetz) does not allow censorship however there are some restrictions on free speech especially regarding Nazi propaganda."

    Winners sometimes use Gnomes. Prashant writes: "Cygwin is turning out to be a breeze of fresh air for people stuck on windows for one reason or another. I can use the familiar bash shell on any platform(win, *nix) I am on, and don't have to deal with the DOS prompt. I use all the gnu tools from cygwin distro. rcs, cvs, vim, perl, python, ruby, apache the list goes on. Not only that, I successfully ran postgresql on Cygwin. The XFree86 port of Cygwin itself can be huge cost saving over commercial X-servers for Windows. I have tried KDE on Cygwin version 1.1.2. I was impressed with it. Here is something new: GNOME ported to Cygwin as well. Let the rivalry ontinue on Windows.

    It's all about having options. I would love be 100% Linux user but again sometimes it's not you who decides what os runs on your machine. So till Windows gets replaced by Linux by the authorities, happy cygwining."

    This addition brought to you by ... Solar Power! basfromasd writes "The winner of the 3000 km World Solar Challenge race from Darwin to Adelaide has reached the finish in a record breaking time. The winning car, Nuna, was built by the Alpha Centauri team, consisting of 10 university students of TU Delft and University of Amsterdam. Some technical details can be found at their site and at ESA. Results and pictures of the race are at the Centre for Photovoltaic Engineering of UNSW website. Well done for a first time contestant, showing that skill and intelligence can match the resources of factory sponsored teams. They found some good sponsors though: GaAs solar cells are not cheap. Neither are Li-Ion batteries. Some of the solar cells were used in the Hubble Space Telescope before and brought back to earth in 1993. The other cars did not make it before today's curfew. The runner up, Aurora, stopped just outside of Adelaide for the night and is expected to finish tomorrow morning."

  5. Two Shots In The Arm For PPC Linux

    Linux · Linux · · posted by timothy · from the sore-arm dept. · 162 comments
    pinqkandi writes: "SuSE Linux 7.3 PowerPC Edition has now gone into distribution. New for this version are more USB drivers, and improved memory management, among other things. It is now based on Kernel 2.4.12 and glibc 2.2.4. For $79.95 you get it and 2000+ apps on 8 CDs, 550 pages of documentation, and 60 days of tech support." Read on for another nice turn for PPC users with an itch for Free software.

    If updated PPC distributions interest you, this might too: DocTomoe writes: "The staff at iMacLinux have put together one of the largest PowerPC specific Linux resources. The new site called TuxPPC covers all PowerPC hardware. The site is aimed at not just people with Macs who want to try Linux, but at Linux users who might be interested in getting into the PowerPC platform."guides and web forums, too.

    So when will Mandrake release 8.1 for PPC?

  6. Covalent's Version of Apache 2.0 To Drop Monday

    Tech · Apache · · posted by timothy · from the this-will-get-confusing dept. · 85 comments
    kilaasi points out this CNET story about the planned release on Monday of Apache 2.0, "or at least the version that has proprietary extensions. Covalent sells the core of Apache and its own extensions which make it easier to adapt for specific areas and simpler to administer. Covalent is confident that the next generation Apache is mature and is ready for prime time. Covalent employs some of the core members of the Apache-development-team." XRayX adds a link to Covalent's press release, writing: "It's not clear when the Open Source Edition (or whatever) will come out and I didn't find anything at the official Apache Site." Update: 11/10 16:37 GMT by T : Note that the product name is Covalent Enterprise Ready Server; though it's based on Apache software, this is not Apache 2.0 per se. Thanks to Sascha Schumann of the ASF for the pointer.

  7. Using Windows w/ 100% Open-Source Software?

    Ask · Microsoft · · posted by Cliff · from the breaking-as-many-chains-as-possible dept. · 63 comments
    XRayX asks: "I'm currently installing a Windows 98 PC and I'm trying to install just Open Source Software (except Windows and Drivers). Okay, there's Freeamp, GIMP, Mozilla, OpenDivX, VirtualDub, Audacity, Abiword, Tuxracer and FlaskMPEG for Windows; but I'm still missing some good Open Source Tools for Windows: a picture viewer and a GUI Zip-program. Can anyone help?" While an interesting thing to try, I don't think it will be as easy as it sounds. How many others of you have tried to pull this off and how successful were you?
