AMD Details Next-Gen Kaveri APU's Shared Memory Architecture 128

Posted by timothy from the grander-unified-theory dept.
crookedvulture writes "AMD has revealed more details about the unified memory architecture of its next-generation Kaveri APU. The chip's CPU and GPU components will have a shared address space and will also share both physical and virtual memory. GPU compute applications should be able to share data between the processor's CPU cores and graphics ALUs, and the caches on those components will be fully coherent. This so-called heterogeneous uniform memory access, or hUMA, supports configurations with either DDR3 or GDDR5 memory. It's also based entirely in hardware and should work with any operating system. Kaveri is due later this year and will also have updated Steamroller CPU cores and a GPU based on the current Graphics Core Next architecture." bigwophh writes links to the Hot Hardware take on the story, and writes "AMD claims that programming for hUMA-enabled platforms should ease software development and potentially lower development costs as well. The technology is supported by mainstream programming languages like Python, C++, and Java, and should allow developers to more simply code for a particular compute resource with no need for special APIs."

Red Hat 'Fedora-izes' JBoss With New WildFly Java Application Server 40

Posted by timothy from the estrangeder-and-estrangeder dept.
darthcamaro writes "The JBoss Application Server is no more. Just like Red Hat killed Red Hat Linux in 2003 to make way for Fedora, the same is now happening with JBoss and the new WildFly project. 'There was of course the application server, there are a number of JBoss commercial products, there was the community site, etc., so when you asked someone "What is JBoss?" the answer was varied,' Jason Andersen, director, product line management, at Red Hat, explained. 'What we wanted to do was cement the idea that JBoss is a portfolio of middleware products and not just the application server.'"

Java 8 Delayed To Fix Security 135

Posted by Soulskill from the projected-release-2047 dept.
mikejuk writes "Java Development Kit 8, planned for September 2013, is being delayed until next year because of 'a renewed focus on security.' Java has been having security publicity problems recently, but Oracle now seems to be taking them more seriously. Mark Reinhold, chief architect of the Java platform group, said, 'Maintaining the security of the Java Platform always takes priority over developing new features, and so these efforts have inevitably taken engineers away from working on Java 8.' The major change still to be made to Java 8 is Project Lambda, which Reinhold says is 'the sole driving feature of the release.' He laid out alternatives, such as dropping Lambda from this release, but said Oracle has decided instead to wait until Lambda is ready. The revised schedule for JDK 8 has a developer preview scheduled for September, a release candidate scheduled for January 2014, and general availablity scheduled for March 2014. The delay means that Java SE 9 will probably be released in early 2016, rather than late 2015."

Oracle Fixes 42 Security Vulnerabilities In Java 211

Posted by samzenpus from the patching-things-up dept.
wiredmikey writes "Oracle released its quarterly Critical Patch Update (CPU) for April, which addressed a whopping 128 security issues across multiple product families. As part of its update, Oracle released a Java SE Critical Patch Update to plug 42 security holes in Java, 19 with base CVE score of 10 (the highest you can go) and 39 related to the Java Web Start plugin which can be remotely exploited without authentication. According to security analyst Wade Williamson, organizations need to realize that Java will continue to pose a significant risk. 'The first step is for an organization to understand precisely where and why Java is needed,' Williamson wrote. 'Based on the rate of newly discovered vulnerabilities, security teams should assume that Java is and will continue to be vulnerable.' Organizations should to take a long, hard look at Java and answer for themselves if it's worth it, Williamson added. Due to the threat posed by a successful attack, Oracle is strongly recommending that organizations apply the security fixes as soon as possible."

Ask Slashdot: Building a Web App Scalable To Hundreds of Thousand of Users? 274

Posted by Soulskill from the get-up-in-that-there-cloud dept.
AleX122 writes "I have an idea for a web app. Things I know: I am not the first person with a brilliant idea. Many others 'inventors' failed and it may happen to me, but without trying the outcome will always be failure. That said, the project will be huge if successful. However, I currently do not have money needed to hire developers. I have pretty solid experience in Java, GWT, HTML, Hibernate/Eclipselink, SQL/PLSQL/Oracle. The downside is project nature. All applications I've developed to date were hosted on single server or in small cluster (2 tomcats with fail-over). The application, if I succeed, will have to serve thousands of users simultaneously. The userbase will come from all over the world. (Consider infrastructure requirements similar to a social network.) My questions: What technologies should I use now to ensure easy scaling for a future traffic increase? I need distributed processing and data storage. I would like to stick to open standards, so Google App Engine or a similar proprietary cloud solution isn't acceptable. Since I do not have the resources to hire a team of developers and I will be the first coder, it would be nice if technology used is Java related. However, when you have a hammer, everything looks like a nail, so I am open to technologies unrelated to Java."

Apache Terminates Struts 1 61

twofishy writes "Struts 1, the venerable Java MVC Web framework, has reached End Of Life status, the Apache foundation has announced. In a sense, the move simply formalises what has already happened, as the Struts team have focused their efforts on version 2; the last release of Struts 1 was version 1.3.10 in December 2008. The change of status does mean however that, whilst the code and documentation will still be available, no further security patches or bug fixes will be issued."

Ask Slashdot: Preparing For the 'App Bubble' To Pop? 240

Posted by Soulskill from the covering-all-your-bases dept.
Niris writes "I am currently a senior in computer science, and am expecting to graduate in December. I have an internship lined up in Android development with medium sized company that builds apps for much larger corporations, and I have recently begun a foray into iOS development. So far my experience with Android ranges from a small mobile game (basically Asteroids), a Japanese language study aid, and a fairly large mobile app for a local non-profit that uses RSS feeds, Google Cloud Messaging and various APIs. I have also recently started working with some machine learning algorithms and sensors/the ADK to start putting together a prototype for a mobile business application for mobile inspectors. My question: is my background diverse enough that I don't have to worry about finding a job if all the predictions that the 'app bubble' will pop soon come true? Is there another, similar area of programming that I should look into in order to have some contingencies in place if things go south? My general interests and experience have so far been in mobile app development with Java and C++ (using the NDK), and some web development on both the client and server side. Thank you!"

Oracle Clings To Java API Copyrights 207

Posted by samzenpus from the hold-on-tight dept.
An anonymous reader writes in with a story about some of the ramifications of the Oracle-Google lawsuit. "You could hear a collective sigh of relief from the software developer world when Judge William Alsup issued his ruling in the Oracle-Google lawsuit. Oracle lost on pretty much every point, but the thing that must have stuck most firmly in Oracle’s throat was this: 'So long as the specific code used to implement a method is different, anyone is free under the Copyright Act to write his or her own code to carry out exactly the same function or specification of any methods used in the Java API. It does not matter that the declaration or method header lines are identical. Under the rules of Java, they must be identical to declare a method specifying the same functionality — even when the implementation is different. When there is only one way to express an idea or function, then everyone is free to do so and no one can monopolize that expression. And, while the Android method and class names could have been different from the names of their counterparts in Java and still have worked, copyright protection never extends to names or short phrases as a matter of law.'"

Massachusetts May Try To Tax the Cloud 172

Posted by timothy from the if-it-moves-tax-it-if-it's-ephemeral-tax-it dept.
CowboyRobot writes "A proposed tax in Massachusetts may affect software services and Web design and hosting. If approved, the state estimates the tax may bring in a quarter billion dollars in 2014 by expanding its tax on 'canned software' to include some elements of cloud computing. The tax would cover custom-designed software and services based in the cloud. "Custom" software includes the design of Web sites, so the cost to local businesses of a new Web site would increase by 4.5% on contracts to design the site, write Java, PHP or other custom code. The cost of site hosting and bandwidth would also be taxed."

Apple Nabs Java Exploit That Bypassed Disabled Plugin 97

Trailrunner7 writes "Apple on Thursday released a large batch of security fixes for its OS X operating system, one of which patches a flaw that allowed Java Web Start applications to run even when users had Java disabled in the browser. There have been a slew of serious vulnerabilities in Java disclosed in the last few months, and security experts have been recommending that users disable Java in their various browsers as a protection mechanism. However, it appears that measure wasn't quite enough to protect users of some versions of OS X."

Comparing the C++ Standard and Boost 333

Posted by Soulskill from the shaping-an-industry dept.
Nerval's Lobster writes "The one and only Jeff Cogswell is back with an article exploring an issue important to anyone who works with C++. It's been two years since the ISO C++ committee approved the final draft of the newest C++ standard; now that time has passed, he writes, 'we can go back and look at some issues that have affected the language (indeed, ever since the first international standard in 1998) and compare its final result and product to a popular C++ library called Boost.' A lot of development groups have adopted the use of Boost, and still others are considering whether to embrace it: that makes a discussion (and comparison) of its features worthwhile. 'The Standards Committee took some eight years to fight over what should be in the standard, and the compiler vendors had to wait for all that to get ironed out before they could publish an implementation of the Standard Library,' he writes. 'But meanwhile the actual C++ community was moving forward on its own, building better things such as Boost.'"

Book Review: Hadoop Beginner's Guide Screenshot-sm 57

Posted by samzenpus from the read-all-about-it dept.
First time accepted submitter sagecreek writes "Hadoop is an open-source, Java-based framework for large-scale data processing. Typically, it runs on big clusters of computers working together to crunch large chunks of data. You also can run Hadoop in "single-cluster mode" on a Linux machine, Windows PC or Mac, to learn the technology or do testing and debugging. The Hadoop framework, however, is not quickly mastered. Apache's Hadoop wiki cautions: "If you do not know about classpaths, how to compile and debug Java code, step back from Hadoop and learn a bit more about Java before proceeding." But if you are reasonably comfortable with Java, the well-written Hadoop Beginner's Guide by Garry Turkington can help you start mastering this rising star in the Big Data constellation."

Emerging from the proceedings, it was learned that Alsup himself had some programming background and wasn't bedazzled by Oracle's thin arguments on the range-checking function. The ruling came, programmers rejoiced and Oracle vowed Appeal. It seems that time is coming now, nearly a year later, as Microsoft, BSA, EMC, Netapp, et al. get behind Oracle to overturn Alsup's ruling citing 'destabilization' of the 'entire software industry.'"

Why My Team Went With DynamoDB Over MongoDB 106

Posted by timothy from the mostly-for-the-web-scale-of-it dept.
Nerval's Lobster writes "Software developer Jeff Cogswell, who matched up Java and C# and peeked under the hood of Facebook's Graph Search, is back with a new tale: why his team decided to go with Amazon's DynamoDB over MongoDB when it came to building a highly customized content system, even though his team specialized in MongoDB. While DynamoDB did offer certain advantages, it also came with some significant headaches, including issues with embedded data structures and Amazon's sometimes-confusing billing structure. He offers a walkthrough of his team's tips and tricks, with some helpful advice on avoiding pitfalls for anyone interested in considering DynamoDB. 'Although I'm not thrilled about the additional work we had to do (at times it felt like going back two decades in technology by writing indexes ourselves),' he writes, 'we did end up with some nice reusable code to help us with the serialization and indexes and such, which will make future projects easier.'"
