Submission + - Java EE 5 SDK Update 2 is Out

nazrul writes: "Updated versions of Java EE SDK and Java Application Platform SDK (overview) are now available for download. These new versions are fully tested with JDK 6 as well as JDK 5.0. In addition, the Java Application Platform SDK includes Access Manager (7.1 Beta), JBI Runtime with BPEL from project Open ESB and a beta version of Portlet Container to enable development and testing of JSR 168 portlets. Developer content such as Java EE 5 samples, blueprints, tutorial and API javadocs are also included.

SJS Application Server (9.0 Update 1 Patch 1) based on Project Glassfish is included in the SDK. It contains a performance bugfix that enables record-breaking price/performance on the application tier with SPECjAppServer result of 521.42 JOPS@Standard, 19% improvement from the previous version 8.2 — see Scott's latest blog for all the details.

The Java EE Tools bundle has also been refreshed to use the Java Application Platform SDK Update 2. Check the download page; the Chinese and Japanese regional downloads will be updated very soon."

Submission + - What is a good laptop car mount?

masdog writes: "I have a work vehicle that need a laptop mounted in it. Although I have done a few searches and come across a few companies that make laptop mounts, mainly Jotto Desk and RAM, I haven't been able to find anything on the quality of those products. My boss wants more information before he'll consider cutting a check, and I don't want to recommend a poor quality product.

Slashdot, what is a good car mount for a laptop?"

Submission + - JavaOne 2007 call for papers

LarsWestergren writes: The 2007 JavaOne call for papers closes this friday. According to conference organizer Anetter Vernon, there are currently only a little over 300 submissions so far, but appearently most people do submit at the last minute judging from earlier conferences. New this year is that technical contents doesn't have to be 100% about the Java platform, but can be about for instance scripting, Open Source and community development, consumer technologies, or next generation web. This is one of the world's biggest developer conferences with around 14000 participants last year, so why not hurry up and submit your paper?

Submission + - Java Open Review Project

bvc writes: "We Launched the Java Open Review Project today. We're reviewing open source Java code all the way from Tomcat down to PetStore looking for bugs and security vulnerabilities. We're using two static analysis tools to do the heavy lifting: the open source tool FindBugs, and the commercial tool Fortify SCA. We can use plenty of human eyes to help sort through the results. We're also soliciting ideas for which projects we should be reviewing next. Please help!"

Submission + - Mac Book Pro as Rohmba Remote

adelord writes: Alpha Geeks have a new do-it-yourself project to terrorize the cat with: use Pearl script with a MacBook Pro's Sudden Motion Sensor to control a Rohmba. Wired's Cult of Mac http://blog.wired.com/cultofmac/2006/12/control_a_ roomb.html cites the original site http://hackingroomba.com/projects/roomba-tilt-cont rol-with-macbook-perl/ . This gets my award for most inefficient use of tech, time, and training for the week.

Submission + - End Of Dayz

An anonymous reader writes: End Of Dayz is an eclectic collection of underground text files compiled from Soljo Publishing's full 1992 to 2006 run — a snapshot of creativity and opinion from the digital jilted generation, right from the ASCII edge and onto your bookshelf. Hacking, politics, science, fiction and humour from the group that brought you The Soljo, The Discordant Opposition Journal, SPACT and the RWM Collective. A must read for any self respecting old school geek, or indeed any geek interested in the history and traditions of underground geekdom.
The Internet

Submission + - Map of the Internet

Wellington Grey writes: "Author of the popular webcomic xkcd has put up a hand made map of the internet as today's comic. He also has an interesting blog entry detailing some of the work that went into it, such a pinging servers and creating a method of fractal mapping to display related regions as contiguous sections on the grid."
GUI

Submission + - A close look at OLPC Human Interface Guidelines

feranick writes: There have been a lot of articles on /. about the OLPC project, most of them regarding the hardware, the social impact or the cost of the operation itself. However the software development, specifically in the GUI didn't get so far much attention. This blog summarizes some of the OLPC global interface guidelines. You will see that what really new in the laptop is not the laptop itself, but the completely new idea behind the design, where instead of applications you have activities, documents are now journals, "application bundles can be signed by whoever works on them — because there is a view source key on the keyboard, anybody can modify an app and distribute it.". It really looks like if this is successfully, we could see a new breakthrough in GUI design also in mainstream PCs: "This UI is quite simply one of the deepest and most interesting redesigns of the desktop user interface ever produced. It makes MacOS look like what it is — boring and unoriginal."
Sun Microsystems

Submission + - Sun Microsystems - safeguarding its legacy

An anonymous reader writes: This article analyses the decisions taken by Sun Microsystems over the period of time and notes...
Even though Sun Microsystems has been a pioneer in creating intellectual property, the bulk of its revenue is from the sale of hardware like high end servers, workstations and storage solutions. But it is going all out to make sure that the fruits of its hard work lives on and gains in popularity. It has decided to release Java under a GPL v2 licence, has hinted at releasing Solaris under GPL and now for the first time, perhaps taking a leaf from Ubuntu is distributing Free DVD Media kit comprising of Solaris 10 and Sun Studio 11.

Scientists Developing Commercially Viable Synthetic Gecko 122

Gordon from Seattle writes to mention a CNN article about a new way to hang out. A British aerospace team is working on a super-sticky substance they're calling "Synthetic Gecko". It mimics the hairs on a gecko's foot, and may eventually be developed as a reusable adhesive. From the article: "Each of the microscopic setae on a gecko's foot has a mushroom shaped cap on the end, less than one-thousandth of a millimeter across. This ensures that the gecko's foot is in very close contact with the surface beneath. The cumulative attractive force, called van der Waals force, of these setae allows the lizard to scurry up walls and ceilings, and even hang from polished glass surfaces. In 2003 scientists at the University of Manchester produced a one centimeter patch of 'gecko tape,' but neither the University of Manchester nor University of California teams managed to produce the material in a greater quantity, unlike Haq and Sargent, who have already tested areas larger than 10 centimeters-squared."
Television

Submission + - No more analogue terrestrial TV in the Netherlands

MavEtJu writes: "The Netherlands is the first European country which has switched off its analogue terrestrial signal. According to Signaal op digitaal (dutch for "The signal is going digital") and Screen Digest (a good explanation in english), it won't be a lot of fuzz: Only 74 thousand households will be affected and have to buy a digital decoder because they are still using their own antenna. Is the rest of the Netherlands so apathetic towards television? No, the infrastructure for television has been very centralized: Instead of an atenna on every roof, since the 1960s every suburb had its own big antenna in the middle, with cables going from it to all houses. Later, in the 1980s, the big antennas were replaced by city-based or region-based receiver stations which could pick up both terrestrial and satellite signals. See the dutch Wikipedia for more information about the history of the client-side of the dutch television infrastructure."
Programming

Submission + - Open Source Cell Phone Development

Paul Carver writes: In the cell phone stories that are posted from time to time I've never seen any discussion of open source development. Are there any brands and/or phone OSs that are open to the development of "quick and dirty" applications? I'm not talking about professional development shops, I'm talking about free or low cost "scratch an itch" creation of little apps with little or no commercial potential. In particular, I'm interested in cell phones rather than smart phones since I'm rough on phones and I don't really trust the durability of the big PDA+Phone, but pointers to getting started on PalmOS or Windows Mobile phones will probably help some people.
Java

Submission + - Java EE & Streaming Architectures

Amin Ahmad writes: "Implementing a streaming architecture on a Java EE application server provides asymptotically better memory performance, and, hence, scalability, than current, widely-implemented, Java EE patterns endorsed by Sun. This article provides a concrete implementation of a streaming architecture and compares its scalability to two other, standard implementations: Remote EJB and Local EJB-based solutions. The implementation based on a streaming architecture comes out the hands-down winner: for example, when sending back 300 rows of data to the client, the Local EJB solution fails beyond 16 concurrent users whereas the streaming solution is still running at 128 concurrent users! The article includes complete source code and the entire results database for the stress test. I would be interested in hearing your feedback."
