Eleksen Introduces Electro Fabric
DigitalDame2 writes "Eleksen, a small UK-based firm is introducing electronic fabric, essentially carbon-embedded nylon sandwiched between layers of nylon mesh that, when a milliamps charge is passed through it, can recognize touch, pressure and even the direction and path of a stroke. This thin, flexible, and washable fabric connects to a small 8-bit processor, which then can be connected to a standard electronic device like an iPod. Eleksen company executives said the washable fabric can also withstand extreme pressure; they've rolled a car over it without any ill effects." -
A Workstation for Sensitive Experiments?
etrgQUARK asks: "I am in charge of infrared spectrometers at our research center. One of the setups is used to measure the orientation of monolayers at the air/water interface, i.e. the signal we have to detect is very weak and noisy. We already have a great setup with quality components and electronics, except for one piece of hardware: the computer hooked up to acquire the data. How important is the computer in noise-sensitive data acquisition? What are your experiences? Do you have any suggestions on a workstation suitable for such tasks or is it a waste of money to use anything but the average computer system? Unfortunately, the software used is Windows-only." -
Company Claims Development of True AI
YF 19 AVF wrote to mention a press release on Yahoo from company GTX Global. They think they've got a good thing on their hands, going so far as to claim they've developed the first 'true' AI. From the release: "GTX Global Cognitive Robotics(TM) is an integrated software solution that mimics human behavior including a dialogue oriented knowledge database that contains static and dynamic data relating to human scenarios. The knowledge further includes translation, processing and analysis components that are responsible for processing of vocal and/or textual and/or video input, extracts emotional characteristics of the input and produces instructions on how to respond to the customer with the appropriate substantive response and emotion based on relevant information found in the knowledge base." Somehow I think there is a littler hyperbole here. In your estimation, how close are we to the real thing? -
PCWorld Dubs Firefox Best Product of 2005
Peaceful_Patriot writes "PCWorld's list of the 'Best Products of 2005' is out and Firefox tops the list. Also notables are GMail at number 2, Apple OS X, Tiger at number 3, Skype ranks in at 8 and Ubuntu at 26!" From their Firefox article: "Are you sick and tired of Internet Explorer? Have you grown weary of the constant vulnerabilities and patches? Do you scratch your head at sudden program lockups and crashes? Are you dismayed that Microsoft hasn't lifted a finger to improve or enhance IE since it buried Netscape's Navigator browser at the dawn of the century? Yeah, me too." -
RPGs In The 'Real World'
As more and more people realize the fun they're denying themselves by turning away from orc-bashing and dragon-baiting, mainstream businesses and media are paying more attention to RPGs. Sam the Giant writes "Barnes & Noble University is offering a free 8 hour on-line course titled 'Discover Dungeons & Dragons: Becoming a D&D Player'. The free course is described as follows: 'As a beginning player, this course will guide you in understanding how D&D works, explaining the various worlds and characters types that it is based on, creating a D&D role for yourself, and understanding how your player role interacts in the world and with other characters. You will learn the extent of your abilities and the possibilities that lie ahead for your player, including magical spells, mythic quests, and epic battles with incredible monsters.' It's free to enroll." In the same vein, NPR's great reporting turns to World of Warcraft. Dragoonmac writes "All Things Considered recently ran a feature about WoW communities, farmers, and a humorous review of real-life. A Slashdotter's must hear." -
Innovative Christmas Light Setups?
glitch0 asks: "Recently, I found some pretty neat Christmas decorations, at a neighbors house. He has a light setup that syncs up with MIDI files of Christmas music. The cool part is the way you hear the music - it's broadcast using a radio transmitter so you can tune your car radio as you're driving by and hear and see the show. Do any other Slashdot readers have cool homebrew light setups or ideas for over-the-top holiday decorations?" -
Failing Ocean Current Raises Fears of Mini Ice Age
Designadrug writes "This article from Newscientist paints a picture of a major climate control mechanism teetering on the brink: "The ocean current that gives western Europe its relatively balmy climate is stuttering, raising fears that it might fail entirely and plunge the continent into a mini ice age. The dramatic finding comes from a study of ocean circulation in the North Atlantic, which found a 30% reduction in the warm currents that carry water north from the Gulf Stream."" -
Nose Cells to Cure Spinal Injuries?
dptalia writes "The Guardian has an article on how nose cells may cure spinal injuries. This technique has worked with rats, restoring feeling and movement to limbs damaged by severed nerves. The initial trial will be on people who have lost control of an arm due to the nerves being pulled from the spinal cord." From the article: "If successful, with refinement and research the procedure could be tried on people in a wheelchair. It also has the potential to heal other nerve injuries, such as those caused by stroke, blindness and deafness." -
Solutions for Small Business VoIP?
MajorBlunder asks: "I'm part of the IT department of a small but prospering software company. We have recently filled the capacity of the POTS PBX phone system we currently have installed. We are currently looking into switching over to a VoIP phone system. We have a sizable IT staff in proportion to the rest of the company, so we'd like to be able to maintain the hardware/software in house as much as possible. I wanted to ask the Slashdot readership what experiences they have had with switching over to from POTS to VoIP. Any recomendations for full end to end solutions would be appreciated, and recomendations of things to avoid would be great." -
Hackers Happily Hacking The 360
m3lt writes "Hackers have purchased the XBox 360 so they will have generation 1 models, which are more prone to security flaws. At hackaday there is an article about Xbox 360 First Impressions. More importantly though, it looks as if homebrew browsers are already showing up for the Xbox 360." Additionally, geekylinuxkid writes "It looks like another bounty is being offered for linux on a console. This time it is for the xbox 360 and is provided by the guys at free360.org. Join in, donate, and contribute to the community." -

Pandora Radio from Music Genome Project
kramthegram writes "The Music Genome Project, an attempt to define music by it's traits in a way similar to DNA defines traits in humans has led to the development of Pandora. Pandora uses the song choices you make to see what traits appeal to you and present you with custom radio station. While limiting you to thumbs up or thumbs down, the "gene" heuristics allows for a very quick adaptation to your musical tastes." Not sure how deep it goes, and I'm not sure I like that it led me from The Who to Styx and Def Leppard. But this is a neat little tool for discovering new music. -
Cyber Monday Doesn't Exist
xsspd2004 writes "Despite a huge amount of hype, the Monday after Thanksgiving is historically only the 12th-biggest online shopping day of the year. Do a Google search on "Cyber Monday," and you get as many as 779,000 results. Not a bad haul for a term that was created just a week and a half ago." -
Lockheed Martin Selects Linux for Missile Defense
m3lt writes "Business Wire is reporting that Concurrent announced today that Lockheed Martin Space Systems has selected RedHawk(TM) Linux as the operating system for their United States Army Theater High Altitude Area Defense (THAAD) program." From the article: "Lockheed Martin selected RedHawk for the THAAD program due to the precision and guaranteed response time of Concurrent's RedHawk Linux real-time operating system. Only RedHawk Linux was able to ensure the high frame rates required in their HIL simulation without frame overruns, thereby ensuring the highest quality of system test." -
Bionic Hands to Become a Reality Soon?
Spy der Mann writes "A highly dexterous, bio-inspired artificial hand and sensory system that could provide patients with active feeling, is being developed by a European project called cyberhand. The final prototype includes sensors for tension, force, joint angle, end stroke and contact." -
NES Controller MP3 player hack
Skadet writes "Martin Kersch of Germany made great use of a boring Saturday afternoon by transforming an ordinary USB Stick and NES Controller into an MP3 Player (original German). He even hacked the buttons on the controller to work with the mp3 player, "Start" is On/Play, and the directional pad functions as the song changer/volume control. Do you remember those NES Controller Belt Buckles? They should integrate these MP3 Players into those things." -
Ubuntu Certified for IBM DB2
xsspd2004 writes "Ubuntu Certified for IBM DB2 -- Ubuntu is moving into Enterprise computing with IBM's certification of Ubuntu as "Ready for IBM DB2 Software for Linux". " -
Dutch Court Orders Lycos to Reveal Client
linumax writes to tell us InformationWeek is reporting that the Dutch Supreme Court ruled against Lycos last Friday stating that they wrongly protected the identity of a user who posted "slanderous allegations" against an internet postage-stamp dealer. From the article: "The dealer and claimant, identified in court documents only as A. Pessers, took Lycos to court in 2003, seeking the details of its client so he could pursue financial damages allegedly resulting from the allegations." -
A Storage Solution for Lots of Digital Photos?
Duizendstra asks: "I've been asked to explore the digital storage possibilities for a professional photographer. One of the characteristics is the rapid growth of the amount, and size of pictures. At the moment, one photo session produces about 2 GB of raw data. He has an Apple - Power Mac G5, and he currently uses DVD as his storage medium. However, he has lost quite a few photos because of DVDs that can't be read anymore. I would like to know if any Slashdot readers have any experience in creating a solution for such a problem? Any help/idea(s) would be greatly appreciated!" -
MS Has Free Software Removed From U.N. Paper
linumax writes "Microsoft asked for references to free software to be removed from a document presented at last week's UN World Summit on the Information Society (WSIS) conference, the software giant admitted on Friday. The Free Software Foundation Europe (FSFE) is unhappy that the document was changed and claims that even though it was on the panel discussing the document, it was not made aware of Microsoft's changes. The document (2.8MB PDF), known as the Vienna Conclusions, discusses issues around IT and creativity. The original draft of the document discussed how the free software model is changing the way people do business." -
Functional Paper V8 Engine
glitch0 writes "This V8 Engine made entirely out of paper with the exception of a few parts (motor, wires, etc.), is fully functional. It features many moving parts which include "a compound crankshaft, a rapid cooling fan, 8 rods, 8 pistons and a complex compound gearbox etc." The engine is powered by 2×1.5V D Batteries and weighs 2.98kg. From start to finish this model took one year to design and construct. There is even a D.I.Y. kit in the works that will be released shortly at the price of $85 USD. What comes next...a fully functional car made out of paper?" -
Email On Both the Desktop and the Laptop?
RapterOfParadox asks: "I recently purchased a new laptop and have everything configured except for my e-mail. I've always liked having a single location where I know my e-mail is safe, secure and gets backed up automatically. If I've needed access to new messages then I use webmail, since I close down the email client when I leave the house. I'm currently using Outlook XP for my desktop and was thinking about using the same for my laptop. My only issue is that I'm a little weary about using only my laptop for storing e-mail, since it's a lot more likely to fail. I've been thinking about just synchronizing my Outlook data directories at login, or even using IMAP. Has anyone seen/bought/built an e-mail client that will allow me to have my main e-mail client on my desktop and then update my laptop e-mail client when ever I'm in range, or through a personal IMAP Server?" -
Wireless/Wired Router Solutions for 2 Networks?
DaveTheBrave asks: "I'm currently running a home based business on an el cheapo Netgear wireless router off a broadband cable modem connection. I'm looking to upgrade to something better with more flexibility. My in-laws recently sold their home and will be moving into my home temporarily while they are building another. They have a home based business and my mother-in-law is also notorious for attracting viruses, adware and other nasty stuff on her PC (which I have to routinely clean - hence my need for a better network solution). What is the best/easiest solution to segment and keep separate my network from theirs (both wired and wireless) off of one incoming cable modem? I'm looking for something around or less than $500." -
Faster DNA Testing
tkjtkj writes "Physorg.com is reporting that a Rochester,NY, company, 'Thermal Gradients, Inc' has produced a new method of DNA analysis that can reduce the required time from hours to minutes that the usual 'Polymerase Chain Reacion' (PCR) takes to produce the large quantity of sample DNA needed to identify the donor. This could,conceivably, make "Instant DNA Identification" a reality! Will air travel now require one to arrive at the airport 5 minutes earlier than usual, to provide a skin-swab sample before boarding the plane?" -
Capcom Classics Collection Remixed for PSP
JamesO writes "Capcom has announced Capcom Classics Collection for the PSP, featuring 20 games and wireless multiplayer. Featuring twenty classic games, wireless ad hoc multiplayer, and horizontal and vertical screen orientation, Capcom Classics Collection Remixed is sounding like the retro collection to buy in 2006. Some of the twenty games included in the collection are 1941, Avengers, Block Block, Captain Commando, Magic Sword, Quiz and Dragons, Street Fighter, Strider, Three Wonders, and Varth. Some of those titles aren't exactly well known, but the inclusion of Strider is sure to excite many a gamer. This was one of the notable absences of the recent Capcom Classics Collection for PlayStation 2 and Xbox, so the inclusion of the game on PSP version is a real feather in its cap. " -
IT Workers Worst Dressed Employees
Poorly Dressed Anonymous Coward wrote to mention are article run in the Syndney Morning Herald saying that IT workers have been dubbed the worst dressed corporate employees. From the article: "Help-desk staff were named as the worst offenders, followed by those working in technology start-ups, many of whom had continued to wear T-shirts to work as a consequence of the casual web culture of the '90s. 'The internet is now such a massive industry but people haven't caught up in terms of their dress'." -
Slashback: IP Protection, ReligiousDocument, LiPS Savings
Slashback tonight with updates and clarifications on recent Slashdot stories, including some more fuel for the Sony fire, a closer look at the Intellectual Property Protection Act, ministers jumping on the OpenDocument bandwagon, another spammer gets his due, founding members of the new LiPS board speak out and more - read on for details.Sony leading a price-fixing cartel? Sheridan writes "Hot on the heels of the SonyBMG XCP rootkit fiasco The Times is reporting that Sony may have been charging online retailers up to 15% more for its products than high street outlets in an attempt to block online bargains from forcing prices down. Perhaps they're trying to recoup some of their losses on the rootkitted CDs, although somebody ought to let them know that most of their loss was to their reputation, which this certainly won't help."
Deconstructing the IP protection act. Brent writes "Ars Technica takes a more in-depth look at the Intellectual Property Protection Act of 2005 and shows that some of the original fears of the Act were overstated. The article states that the act is primarily concerned with criminal acts of infringement, namely infringement done for commercial gain or competitive advantage, and not with criminalizing the mere attempt at commonplace infringement. In short, the act is aimed at commercial piracy. The article also ends with an reasonable challenge to the US government, including the call for a referendum on consumer rights and the penalization of the use of any digital rights technology that impedes fair use."
Even the clergy are jumping into the OpenDocument fray. da6d writes "The LXer has an article about clergy joining the fray surrounding Microsoft's refusal to support OpenDocument. From the article: '[they] see Microsoft's stance as intentionally withholding support so that it can turn a technical business decision into a political fight. By refusing to support OpenDocument, Microsoft is ignoring the cross-platform document sharing needs of visually impaired users, not only in Massachusetts, but also in the other 49 states, not to mention the rest of the world. The economically disadvantaged will also suffer from the lack of Opendocument support in Microsoft Office.'"
UK spammer gets his due. delete writes "Notorious UK internet spammer Peter Francis-Macrae, who referred to himself as "weaselboy", has been convicted of fraud. The 23-year-old earned more than £1.5 million through his activities, primarily through spam mails offering the registration of unavailable domain names. Up to £425,000 of his earnings remain unrecovered."
Linux to make smartphones and high end communication devices cheaper. nitinah writes "In an interview with Phonemag, the founders of LiPS comment that mainstream adoption of Linux would make smartphone and high end communication devices more affordable than ever before. Founding members John Ostrem, lead scientist of PalmSource and Michel Gien, EVP of Jaluna also commented that Linux would also extend the economics to not just phones but applications and services."

Meet the Man Who Will Save the Internet
UltimaGuy writes to tell us The Register is running an interesting piece about Masood Khan, chairman of the sub-committee that is takling many of the difficult questions about internet governance. Mr. Khan has been able to draw enormous respect for many of the participatory nations and seems to have a very direct style of management. From the article: "I would encourage you all not to focus on general themes of internet governance but instead go to the heart of the matter," were Khan's opening words. And then he listed them. "The question of a future mechanism, the question of oversight, and the paradigm of co-operation amongst all stakeholders." -
Water Vapor Causing Climate Warming
karvind writes "According to BBC, new studies suggest that water vapor rather than carbon dioxide in the atmosphere is the main reason why Europe's climate is warming. The scientists say that rising temperatures caused by greenhouse gases are increasing humidity, which in turn amplifies the temperature rise. This is potentially a positive feedback mechanism which could increase the impact of greenhouse gases such as CO2. Even though 2005 will probably be warmest year, climatologists still differ in opinion" -
Army Develops New Chewing Gum
IEBEYEBALL writes "The Army is developing a new chewing gum to help soldiers fight dental problems in the field. The gum takes the place of brushing teeth, which the soldier in a combat situation might not have time or means to do. This sounds like the perfect solution for the geek on the go!" -
IPv6 Still Hotly Debated
inkslinger77 writes "A significant stumbling block to IPv6 adoption may be IPv4 loyalists who are keen to keep the old protocol in preference to the 'new improved' version, according to a Computerworld Australia article. The article covers the views of Cisco's senior technical leader for IPv6 technologies, Tony Hain and Geoff Huston, a senior Internet research scientist from Asia Pacific Network Information Centre (Apnic)." From the article: "Go to your favourite venture capitalist and say 'I want to be an ISP'. By the time he stops laughing and [finds you want to run] IPv6 - the discussion gets terminated. No one wants to hear this. IPv6 is well ahead of adoption in this market so everyone is deferring. No one is running IPv6, because there is no business case for it ... if we really wanted to leave a legacy to our children we'd review the crap we have today which is pretty ghastly ..." -
Trojan Using Sony DRM Rootkit Spotted
Analise writes "The Register reports on the first trojan using Sony's DRM rootkit. A newly discovered variant of the Breplibot trojan makes use of the way Sony's rootkit masks files whose filenames begin with '$sys$'. This means that any files renamed this way by the trojan are effectively invisible to the average user. The malware is distributed via an email supposedly from a reputable business magazing requesting that the businessperson verify his/her attached 'picture' to be used for an upcoming issue. Once the payload is executed, the trojan then installs an IRC backdoor on affected Windows systems." -
Slashback: OpenDocument, Intelligent Design, More DRM
Slashback tonight brings a few corrections, clarifications and updates to previous Slashdot stories, including several updates to the Sony DRM rootkit fiasco, another school system's take on intelligent design, some of the first pictures of the much talked about avian flu virus, a sentencing that gives us the first torrent user to get jail time, Bernard Golden weighs in on the continuing Massachussetts OpenDocument debate, and one users commentary on recent announcements to start pay-per-download services for TV shows. Read on for the details.Sony still not "getting it". c writes "Mark Russinovich continues his investigation of Sony's DRM as he tries out the official uninstaller. His verdict? 'I've analyzed virulent forms of spyware/adware that provide more straightforward means of uninstall.'" Relatedly Cronos1388 writes "According to the Inquirer an Italian group is also suing Sony over the rootkit." Also, an unexpected side effect of this technology is that script kiddies have been able to leverage Sony's tool to hide unauthorized cheat programs from the watchful eye of MMO creators.
Intelligent design supporters ousted. PMuse writes "The Register and others are reporting that all eight of the members of the Dover, PA school board that had required Intelligent Design to be taught alongside Evolution have been canned by voters in yesterday's election."
What does avian flu look like? DevL writes "Swedish photographer Lennart Nilsson has managed to capture images of a H5N1 (bird flu) virus entering and taking control of a cell. While the text is in Swedish, the images speak for themselves."
Torrent user goes up the river. stinerman writes to tell us that the Hong Kong man who was recently arrested for making several movies available via BitTorrent has had his sentence handed down. Chan aka "Big Crook" uploaded Daredevil, Red Planet, and Miss Congeniality which landed him 3 months in jail.
Golden weighs in on OpenDocument debate. OSS_ilation writes "With so much FUD and anti-FUD flying in the face of Massachusetts' decision to go with OpenDocument, it's no surprise that open source advocate Bernard Golden weighs in with his take on current events."
User says new downloadable television just plain "sucks." Thomas Hawk writes "In the past few weeks the three major studios have all announced deals to begin offering downloadable television for consumers -- Apple/ABC, DirecTV/NBC, and Comcast/CBS. The problem with each of these respective offerings is that they largely suck. Apple sells expensive low res limited television from ABC. NBC's new service will only work on DirecTV DVRs (uh hello McFly, why pay money for this service when I can just record it for free). And CBS' downloadable programming could contain commercials."

Did Apple Sabotage the ROKR?
JPigford writes "The Apple Blog makes claim that Apple sabotaged the success of the ROKR so as to sway public opinion of MP3 cell phones in general...ultimately to drive more sales to the iPod. By mandating a 100 song limit on the ROKR and having the product flop, Apple was able to put a bad taste in the mouths of consumers so that not only do they drive more iPod sales, but they keep competitors from fighting back with their own MP3 phones." -
Australian ISP Unveils WiMax Like Card
krispy78 writes "If you're looking forward to the day your laptop has WiMax built in and can access wireless broadband as easily as WiFi, you're not alone. But the 802.16e mobile WiMax standard is yet to be finalized on paper, and we'll be lucky to see it the first products this side of 2007. In Australia, a wireless PCMCIA card has been released that comes close to the "WiMax ideal". It appears to Windows like a regular WiFi card (no heinous login clients to run) but can pick up wide-area wireless broadband signals. The network that runs the cards ("Navini Ripwave") is apparently being rolled out in USA and other countries too." -
Computer Associates Sells Ingres DB Tech
Christopher B. Brown writes to tell us Network World is reporting that Computer Associates is selling their Ingres database technology to a private equity firm called Garnett & Helfrich Capital. From the article: "CA released Ingres last year as an open source project, reviving interest in the dormant software. Still, databases have never been a core part of CA's portfolio. CA CEO John Swainson cast the Ingres sale as part of CA's larger effort to streamline the vast collection of applications it amassed through a decade of heavy acquisitions in the 1990s. Ingres came to CA through its 1994 buyout of ASK/Ingres" -
No More Lunar Land for Sale
dptalia writes "According to China Daily, Beijing authorities have shut down sales of lunar property. Apparently there's a "Lunar embassy" in China and they've sold 34 people deeds to land on the moon. Not too surprisingly, the government has declared this illegal. The Bejing office claims to be a satellite of the U.S. Lunar Embassy, run by Dennis Hope. Hope claims that while it is illegal for countries to stake a claim on the moon, it is legal for individuals and corporations to." -
Creating a Computational Linguistics College Degree?
$random_var asks: "I am an undergraduate student currently studying Bioengineering. However, I am growing more and more interested in programming and linguistics, which leads me to think that I should define my own major, Computational Linguistics [mit.edu], which google defines as 'a field concerned with the processing of natural language by computers.' When I present my proposal for this degree to the school's advising staff, I would like to have a complete list of all of the topics this major should cover. Having only little experience with computer science and engineering, I'm not sure what parts of that field I should include. Beyond the basic lower-division courses, what specific fields of computer science do you think should be emphasized in a practical undergraduate study of Computational Linguistics?" -
Java Puzzlers
Kylar writes "When you have spare time and decide to do something with a book (That's like an analog webpage, for the neuronauts among us), how often do you turn to a computer related book? How often has it happened in the last year? Right. The problem being that computer books are often either: a) boring, b) difficult to read, c) poorly written, or possibly: d) made of cheese." Read on for the rest of Kylars' review. Traps, Pitfalls, and Corner Cases - Java Puzzlers author Joshua Bloch, Neal Gafter pages 282 publisher Addison-Wesley rating 9 out of 10 reviewer Tom Byrne ISBN 0-321-33678-X summary 95 Corner cases and traps that any serious java developer should be aware of (or entertained by.)
Java Puzzlers is none of the above(*), being well written, amusing, whimsical, and above all, informative. Bloch and Gafter have brought us a book that entertains us with corner-cases, one-in-a-million chances and other happenings that explore the ins, outs, and guts of the Java Programming Language.
Anyone who has been a serious java programmer in the last several years should know the name Josh Bloch, and more importantly, should have read his book Effective Java. Josh, acting as java's platform architect has been directing and guiding Java into it's current incarnation as a mature, robust (Cue the laughter from the peanut gallery) programming language.
This book primarily references the Java 1.5 programming language, and some of the puzzles are 1.5-specific, although a significant portion of the problems are applicable to previous versions. Also, this book is aimed towards people who are competent-to-expert java programmers, and although there is a lot of good information, people who are new to Java will probably be a bit lost. As it stands, I have 7 years of Java experience, and I was only able to figure out about 15% of the puzzles without resorting to code, or more frequently the answer. The reason that I didn't stop to try out most of these problems is that the book is eminently readable, and difficult to put down (unusual for a computer book, and doubly so for one that delves deeply into a language specification document.)
This book dives into a lot of esoteric bits of the Java Language Specification, also known as "The Big Paper That Sometimes Tells Us Why Java Acts Like That," and there are lots of bits in there that don't even make sense, let alone seem intuitive.
Divided into 10 parts, each part presents a series of different code problems that usually present a small method or class that looks innocuous, but in reality exposes a piece of behavior that is strange, spectacular, or, more often, completely confusing. The book exposes flaws in the language, including one of my personal pet peeves, their inability to have a consistent Date object, and this is noted in Puzzle 62 by my favorite line in the book: "The lesson for API designers is: If you can't get it right the first time, at least get it right the second..."
One topic that I found was a continually recurring theme had to do with handling primitives and what happens when they are cast into different types. Java provides a lot of ways to deal with primitives, and for the most part, they play nicely with each other. There are several occurrences that really surprised me. A perfect example is the following innocent statements:
byte b = -1;
char c = (char)b;
so c=-1, right? Wrong. Places like this are things that you could potentially knock your head against the wall trying to figure out why something doesn't do what it appears to do.
(In this case, byte is signed, char isn't, and the widening cast fills in bits, leaving c=65535.)
A good job is also done describing best-practices for API and library designers, as well as us, the more mundane programmers.
The only downside (from my background and point of view - that of an applications architect, and not generally as a language or API designer) - is that some of the amazing optical illustrations can cause dizziness and nausea - although I can't guarantee that won't happen by the loops and twists that your mind will be tied into because of the puzzles.
Lastly, Bloch & Gafter include an appendix that serves as a summary to all the pitfalls and traps that are introduced in the book, and almost could be an appendix to Bloch's 'Effective Java'.
The bottom line is that in reading this book I learned a fair amount about several edge cases and issues that I had actually encountered - and it increased my understanding as to HOW java does things - although I'm fairly certain that I'll never understand the WHY. And most of all - I enjoyed this book, from start to finish, and that's rare, and worth the time.

Vatican Rejects Intelligent Design?
typobox43 writes "A Vatican representative has expressed a defense of the theory of evolution, stating that it is "perfectly compatible" with the Genesis story of creation. "The fundamentalists want to give a scientific meaning to words that had no scientific aim," he said at a Vatican press conference. He said the real message in Genesis was that "the universe didn't make itself and had a creator"." Of course, it'd probably be best if fundmentalists actually talked to, say, the rabbis who wrote the whole thing down. The Orthodox rabbis I've spoken find it amazingly amusing that people take the creation story as literal truth, rather then a story about YHWH's power. -
Philips amBX: For Ambient Gaming
JamesO writes "Philips has announced amBX, a technology which is said to extend the gaming experience out into the real world. amBX, developed by the Surrey based Philips amBX Group, is a technology that will take gamers a step closer to a full sensory experience, with amBX enabled games providing gamers with the ability to use light, colour, sound, heat and airflow in the real world during gameplay. The technology uses a scripting language to enable games to send signals to compatible hardware such as lights, fans, heaters, and even furniture. This means that in a game the lights in your room will match up to the environment you are gaming in. E.g. Green for jungle and blue for the ocean. Strobes of while light could simulate a lightning storm and a burst of air from a fan could make huge jumps feel more realistic." Finally, my master goal of a game called "Bacon Fryer" can be brought to the level I've always: wafts of pork smell in the air, grease burns on your hands for bad flipping. And just wait until you have to pour the grease out of the pan! -
Backup Solutions for Small Tech Companies?
Brushfireb asks: "This has been hit on before, but given the cheap cost of hard drives, larger capacities and speed increases in possible storage (USB2, FIOS, etc) we though that an update would be really helpful. Here's the scenario: We are a small tech company and we have an assortment of workstations (Macs, Linux and Windows desktops), and servers (Web, Database, File, e-Mail, DNS, etc) that run on different Linux distributions. What advice or recommendations do Slashdot readers have for our needs that: won't break the bank; won't force us to take our servers down for an extended period of time (our servers must run 24/7); are reliable; and are easily to maintain. What are some typical mistakes that small tech companies make when it comes to backing up? What software and hardware do Slashdot readers use to accomplish these tasks in similar situations?" -
Online vs. Traditional Degrees?
Justin Rainbow asks: "As a computer science student, avid internet user and full-time programmer I find it very appealing to finish my CS degree online. Finishing at least a year early and studying whenever I want are just a couple of the draws to the online campus. However, are these internet degrees even worth the paper their printed on? Is an online degree just a waste of money? Can an online degree give you just as many opportunities as a traditional university? Has anyone in the Slashdot community graduated from one of these online schools? Did it help or hurt your career? What about graduate school admissions? Does an online degree hurt your chances to get into a great graduate school?" -
GPL 3.0 Rewrite Drive Is No Democracy
linumax writes "Users will be free to comment on the upcoming complex and technical draft versions of the GNU General Public License 3.0 in an easy way, according to Eben Moglen, general counsel for the Free Software Foundation. However, Moglen said Wednesday, speaking at the Open Source Business Conference here, the rewrite of the GPL is not an election and there will be no voting on its clauses. In a session entitled GPL 3.0: Directions, Implications, Casualties, Moglen said that when GPL 2.0 was promulgated some 14 years ago, very few people cared about it. On the advice of a few dozen people and a couple of lawyers, it was written and released. "That was a fine system then. It is not a fine system now. I expect the process around GPL 3.0, when it begins in some 60 to 90 days' time, to collect a great deal of comment from people on the draft documents... ", He said." -
IBM Slows the Speed of Light
dptalia writes "According to an article on ZDNet, IBM has come up with a way to slow light to 1/300 of its normal speed. While this has been done in laboratories before, IBM has found out how to do this using standard materials, which opens the possibility of mass production. This means that the dream of having optical based CPUs may be closer than previously thought." From the article: "When the optical conversion might start to occur is a matter of speculation. Luxtera has said it will start to commercially produce products in 2007. The computer industry, however, tends to move slowly when it comes to major overhauls of computer architecture. Several components will have to be developed before photons can replace electrons inside computers. A paper providing details on the chip will run in Nature on Wednesday." -
Slashback: DRM, MPAA, ADSL
Slashback tonight with a response from Sony that removes the DRM 'rootkit' that has caused so much commotion, more hijinks from the MPAA, continued battery advancement, a followup to the UK broadband plan that had so many American's drooling, a catch in the recent Netflix settlement, and continued financial trouble for Silicon Graphics. Details on these stories and more, below.It's not evil, but just in case... gmr2048 writes "Sony seems to have heard the commotion. They have offered a "Service Pack" to uninstall the DRM Rootkit. From the announcement: 'This Service Pack removes the cloaking technology component that has been recently discussed in a number of articles published regarding the XCP Technology used on SONY BMG content protected CDs. This component is not malicious and does not compromise security. However to alleviate any concerns that users may have about the program posing potential security vulnerabilities, this update has been released to enable users to remove this component from their computers.'"
Obviously they have never heard the adage about deep pockets. Dieppe writes "The MPAA is at it again. This time they're suing a grandfather who didn't cave into the $4,000 blackmail offer for movie downloads his grandson downloaded from iMesh. Four movies in total, and they already owned 3 out of 4 with the grandson deleting them soon after download. This time the MPAA wants "as much as $600,000" in damages. The article also claims that "illegal downloading" costs the industry $5.4 billion per year. Not sure where the MPAA comes up with these figures."
Longer life and no charge time. It doesn't come easy writes "A press release from A123Systems announces another new lithium-ion battery technology that promises to deliver unprecedented performance (according to them). The technology is suppose to deliver 10 times the cycle life and 5 times the power over conventional lithium technology, and only require 5 minutes to recharge to 90% capacity. This is certainly not the first breakthrough for lithium based batteries that has been promised. I wonder if there is a patent lawsuit in the making?"
Fast net connection, but only if you live nearby. conJunk writes "The BBC is running an article about the ADSL2+ that touted a 24MB/s net connection. It seems that this number in fact only holds up if you live across the street from the service provider."
Always read the fine print. JeremyWall writes "The recent Netflix class action settlement has a catch. While it is nice that the average subscriber will be upgraded for one month for free, if you read the fine print in section 4.2 of the long form [PDF Warning] of the settlement you find that you will be automatically charged for the higher subscription going forward. If you don't opt back out when you get their email, you are gonna get charged from then on. If you opt in for the settlement - check your email box regularly!"
Know when to hold and know when to fold. psykocrime writes "According to a recent press release SGI stock has been delisted by the New York Stock Exchange, as a result of falling below the NYSE's minimum share price." SGI, the former darling of the high-tech world, has been in trouble for a while, perhaps this is really the end.

Novell to Release 20% of Their Employees?
sicariusdracus writes to tell us that Ron Hovsepian, the new president and COO of Novell may have his hands full in the near future. Ron has been tasked with getting the troubled business back on track which many have speculated could result in more than 20% of the 5,800 man workforce getting a pink slip (although Hovsepian suggests that may be an over exaggeration). Part of the restructuring will be announced with Novell's fourth-quarter financial results. -
Sony Says No To Central PS3 Online Service
Saige writes "Online gaming fans are going to have to look past the PS3 to get their fix - Sony has announced that they are not doing a central service for PS3 online gaming. Instead, it will be done in the same manner as the PS2, where each company decides what effort to put into it. Considering how weak the online support has been for the PS2, this may not bode well for Sony, especially with more and more rumours that they won't be launching until at least the 2006 holidays." With the Live service such a success and Nintendo rolling out its WiFi network, it seems odd that Sony isn't going to try for something similar. -
A Closer Look at Star Wars on Film and Off
mclove writes "Revenge of the Sith comes out on DVD today, and there's an interesting article on Slate dissecting the now-complete trilogy as the avant-garde, intellectual sort of film that Lucas keeps saying it is."` Relatedly inkslinger77 writes "ILM model maker, Brian Gernand, speaks about what it is like to work with George Lucas and why he thinks Star Wars attracts such a huge following, particularly among the IT community. He also gives some information about the technology that is used behind the scenes. " -
Identity Theft-What Can Really be Done w/o a SSN?
TheItalianGuy asks: "Many of us that work in the financial sector are bombarded with daily security threats. One of the biggest these days is Identity Theft. My fellow comrades and I have been really grilling each other on differing scenarios on what could be done with what information. However, it all seems to come back the the Social Security Number. Financial companies have other controls in place (customer service verification checking, account passwords, etc) to ensure identification. But in order to be of any use, a bad guy would really need someone's SSN. Absent of that, other information would be useless. Right? That's what I would like to ask Slashdot folks. What could be realistically done with customer information without a SSN? Account numbers, address, maybe a phone or payment amount. Is that really dangerous to the customer if only those get compromised?"
