Ask Slashdot: Node.js vs. JEE/C/C++/.NET In the Enterprise? 304

theshowmecanuck writes "I'm working at a small- to medium-sized company that creates software for mobile devices, but came from a 'large enterprise' world before. I see node.js being used increasingly in smaller companies (including ours) or in web/mobile related software. Meanwhile we see languages like Java/JEE, C/C++, and .NET continue to be used for medium-to-large enterprise corporate software. Compared to the status quo in the enterprise (JEE/C/C++/.NET ... and yes, maybe even COBOL) maybe Slashdotters can chime in on how they see Node.js in this role. I'm thinking of things like complexity of business logic (dependencies, workflows, linear processes, etc), transaction support (for processes in general and database support), messaging services, etc. Also, what is the state of Node.js in terms of paradigms like application containers, where much of the 'plumbing' is already set up for you (one of the main benefits of JEE application containers)? But there is also the question of maintainability, deployment, and ongoing operations. What say you, Slashdot?"

Who Will Teach U.S. Kids To Code? Rupert Murdoch 138

theodp writes "For all of their handwaving at Code.org about U.S. kids not being taught Computer Science, tech execs from Microsoft, Google, and Facebook seem more focused lately on Plan B of their 'two-pronged' National Talent Strategy. So, who's going to teach your children CompSci? Enter friend-of-the-Gates-Foundation Rupert Murdoch. Murdoch's Amplify Education is launching an AP Computer Science MOOC this fall (Java will be covered), taught by an experienced AP CS high school teacher (video). An added option, called MOOC Local, will provide additional resources to schools with students in the CS MOOC. MOOC Local will eventually cost $200 per student, but is free for the first year."

How Facial Analysis Software Could Help Struggling Students 90

moon_unit2 writes "Tech Review has a story on research showing that facial recognition software can accurately spot signs that programming students are struggling. NC State researchers tracked students learning java and used an open source facial-expression recognition engine to identify emotions such as frustration or confusion. The technique could be especially useful for Massive Open Online Courses — where many thousands of students are working remotely — but it could also help teachers identify students who need help in an ordinary classroom, experts say. That is, as long as those students don't object to being watched constantly by a camera."

Java 6 EOL'd By Oracle 115

Tmack writes "Not completely unexpected, Java6 has reached EOL. This tidbit shows up in Oracle's Java6 FAQ page, recommending everyone update to Java7: 'Oracle no longer posts updates of Java SE 6 to its public download sites. All Java 6 releases up to and including 6u45 have been moved to the Java Archive on the Oracle Technology Network, where they will remain available but not receive further updates. Oracle recommends that users migrate to Java 7 in order to continue receiving public updates and security enhancements.' Apple just pushed its update 16 which is Java6u51, likely to be one of their last Java6 updates."

Java API and Microsoft's .NET API: a Comparison 319

Nerval's Lobster writes "Previously, developer Jeff Cogswell focused on the respective performances of C# and Java. Now he's looking at yet another aspect of the languages: the runtime libraries—what exactly the libraries are, how they are called, and what features the languages provide for calling into them. Examining the official Java API (now owned by Oracle) and the official .NET API owned by Microsoft, he finds both pretty complete and pretty much a 'tie' with regard to ease-of-use and functionality, especially since Java version 7 release 6 allows for automatic resource management. Read on and see if you agree."

Spikes Detected In Autorun Malware 140

msm1267 writes "Researchers recently have seen a major increase in the volume of autorun malware in some countries, thanks to a couple of new worms infecting those older machines. The two new worms, Worm.JS.AutoRun and Worm.Java.AutoRun, both take advantage of the autorun functionality to spread, and the JavaScript worm has other methods of propagation, as well. Researchers at Kaspersky Lab say that the volume of autorun worms has remained relatively constant over the last few months, but there was a major spike in those numbers in April and May, thanks to the distribution of the two new pieces of malware."

Oracle Reinstates Free Time Zone Updates For Java 7 61

twofishy writes "The internet has been buzzing this week with the news that Oracle has ceased to provide free time zone updates outside of the standard JDK release cycle. However, at the end of yesterday the firm appeared to have a change of heart. 'We never intended for a support contract to be required to keep JDK 7 up to date. TZUpdater was made unavailable on March 8 as part of the End of Public Updates for JDK 6, and as soon as we learned that this affected JDK 7 users we initiated the process of making it available for JDK 7 again.'"

Oracle Discontinues Free Java Time Zone Updates 405

New submitter Noel Trout writes "For a long time in the Java world, there has been a free tool called the 'tzupdater' or Time Zone Updater released as a free download first by Sun and then Oracle. This tool can be used to apply a patch to the Java runtime so that time zone information is correct. This is necessary since some time zones in the world are not static and change more frequently than one might think; in general time zone updates can be released maybe 4-6 times a year. The source information backing the Java timezone API comes from the open source Olson timezone database that is also used by many operating systems. For certain types of applications, you can understand that these updates are mission critical. For example, my company operates in the private aviation sector so we need to be able to display the correct local time at airports around the world. So, the interesting part is that Oracle has now decided to only release these updates if you have a Java SE support contract. Being Oracle, such licenses are far from cheap. In my opinion, this is a pretty serious change in stance for Oracle and amounts to killing free Java for certain types of applications, at least if you care about accuracy. We are talking about the core API class java.util.TimeZone. This begs the question, can you call an API free if you have to pay for it to return accurate information? What is the point of such an API? Should the community not expect that core Java classes are fully functional and accurate? I believe it is also a pretty bad move for Java adoption for these types of applications. If my company as a startup 10 years ago would have been presented with such a license fee, we almost certainly could not have chosen Java as our platform as we could not afford it."

Opposition Mounts To Oracle's Attempt To Copyright Java APIs 187

An anonymous reader writes with a bit from Groklaw: "The remarkable outpouring of support for Google in the Oracle v. Google appeal continues, with a group of well-known innovators, start-ups, and those who fund them — innovators like Ray Ozzie, Tim O'Reilly, Mitch Kapor, Dan Bricklin, and Esther Dyson — standing with [Thursday's] group of leading computer scientists in telling the court that Oracle's attempt to copyright its Java APIs would be damaging to innovation." As usual, Groklaw gives a cogent, readable introduction to the issue.

Ask Slashdot: How Can I Make a Computer Science Club Interesting? 265

plutoclacks writes "I will run a computer science club at my high school next semester with two other friends. The club was newly introduced this school year, and initially saw a massive success (40+ members showed up at the first meeting). Unfortunately, participation has decreased a lot since then, down to four active members. I feel that the main reason for this decline was the inability to maintain the students' interest at the beginning of the year, as well as general disorganization, which we hope to change next semester. The leaders of the club all have fairly strong Java backgrounds, in addition to enthusiasm about computer science and programming. We have a computer lab with ~30 computers, which, though old, are still functional and available for use. What are some ways we can make the club have an impacting interest to newcomers?"

Java Developer Says He Built, Launched Basic Open Source Office Suite In 30 Days 266

alphadogg writes "A freelance Java developer claims it took him only 30 days to build and launch a basic open source office suite that runs on multiple OSes. Called Joeffice, it works on Windows, Mac OS X and Linux as well as in browsers, according to the developer, Anthony Goubard. It includes a very basic word processor, spreadsheet program, presentation program and database software, Goubard said. The office suite was built with NetBeans and uses many popular open source Java libraries. That allowed him to built the program in 30 days, he said, a process that he documented daily on YouTube (video). The suite was released as an alpha version, which means that not everything works yet. Goubard's Amsterdam company, Japplis, launched the suite, which is available under an Apache 2.0 license. This license allows companies to change and redistribute the code internally without having to share the new code publicly, he said."

Why the 'Star Trek Computer' Will Be Open Source and Apache Licensed 129

psykocrime writes "The crazy kids at Fogbeam Labs have a new blog post positing that there is a trend towards advanced projects in NLP, Information Retrieval, Big Data and the Semantic Web moving to the Apache Software Foundation. Considering that Apache UIMA is a key component of IBM Watson, is it wrong to believe that the organization behind Hadoop, OpenNLP, Jena, Stanbol, Mahout and Lucene will ultimately be the home of a real 'Star Trek Computer'? Quoting: 'When we talk about how the Star Trek computer had “access to all the data in the known Universe”, what we really mean is that it had access to something like the Semantic Web and the Linked Data cloud. Jena provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine. ... In addition to supporting the natural language interface with the system, OpenNLP is a powerful library for extracting meaning (semantics) from unstructured data - specifically textual data in an unstructured (or semi structured) format. An example of unstructured data would be the blog post, an article in the New York Times, or a Wikipedia article. OpenNLP combined with Jena and other technologies, allows “The computer” to “read” the Web, extracting meaningful data and saving valid assertions for later use.'" Speaking of the Star Trek computer, I'm continually disappointed that neither Siri nor Google Now can talk to me in Majel Barrett's voice.

Dart Is Not the Language You Think It Is 312

An anonymous reader writes "Seth Ladd has an excellent write-up of Dart: 'When Dart was originally launched, many developers mistook it for some sort of Java clone. In truth, Dart is inspired by a range of languages such as Smalltalk, Strongtalk, Erlang, C#, and JavaScript. Get past the semicolons and curly braces, and you'll see a terse language without ceremony. ... Dart understands that sometimes you just don’t feel like appeasing a ceremonial type checker. Dart’s inclusion of an optional type system means you can use type annotations when you want, or use dynamic when that’s easier. For example, you can explore a new idea without having to first think about type hierarchies. Just experiment and use var for your types. Once the idea is tested and you’re comfortable with the design, you can add type annotations."

Google I/O 2013 Underway: Watch For Updates 115

Google's I/O annual conference is ramping up at San Francisco's Moscone Center. Last year, in the conference keynote, the company took its biggest-yet dive into hardware when it introduced the Nexus 7 tablet, Google Glass, and the ill-fated Nexus Q. The secret is out on Glass, of course: this year, there's a pavilion inside the conference center where I'm sure they'll be showing off applications for it. (Quite a few of the people in the endless lines here are wearing their own, too.) Anticipating the announcements at I/O is practically its own industry, but it's easy to guess that there will be announcements from all the major pots in which Google has its many thousands of (tapping) fingers. Android, search, Chrome, mapping, and all the other ways in which the behemoth of Mountain View is watching what you do. You can watch the keynote talk (talks, really) streamed online from the main conference link above, but this story will be updated with highlights of the announcements, as well with stories that readers contribute. Update: 05/15 16:22 GMT by T : Updates below. Update: 05/15 19:02 GMT by T :Update details: Notes (ongoing) added below on maps, gaming, the Play store, Google+, and more. And, notable, Larry Page is (at this writing) on stage, with an unannounced Q & A session.

To Avoid Confusion: Oracle's Confusing New Java Numbering Scheme 183

twofishy writes "'To avoid the confusion caused by renumbering releases,' Oracle has announced that it is adopting a new numbering scheme for JDK 5.0, JDK 6 and JDK 7. 'The next Limited Update for JDK 7 will be numbered 7u40, and the next 3 CPUs after that will be numbered 7u45, 7u51, and 7u55." The vendor notes that a more elegant solution would require the changing of the version numbering scheme to accommodate different kinds of changes (for example by using 7u44-2 ). However this cannot be implemented outside of a major release, since doing so might break existing code that parses version strings (possibly including the Java auto-update system)" Here's Oracle's announcement.

Massive Amount of Malware Targets Older Java Flaws 102

Trailrunner7 writes "It's no secret that Java has moved to the top of the target list for many attackers. It has all the ingredients they love: ubiquity, cross-platform support and, best of all, lots of vulnerabilities. Malware targeting Java flaws has become a major problem, and new statistics show that this epidemic is following much the same pattern as malware exploiting Microsoft vulnerabilities has for years. Research from Microsoft shows that there has been a huge spike in malware targeting Java vulnerabilities since the third quarter of 2011, and much of the activity has centered on patched vulnerabilities in Java. Part of the reason for this phenomenon may be that attackers like vulnerabilities that are in multiple versions of Java, rather than just one specific version."

Ask Slashdot: Becoming a Programmer At 40? 314

New submitter fjsalcedo writes "I've read many times, here at Slashdot and elsewhere, that programming, especially learning how to program professionally, is a matter for young people. That programmers after 35 or so begin to decline and even lose their jobs, or at least part of their wages. Well, my story is quite the contrary. I've never made it after undergraduate level in Computer Science because I had to begin working. I've always worked 24x4 in IT environments, but all that stopped abruptly one and a half years ago when I was diagnosed with a form of epilepsy and my neurologist forbade me from working shifts and, above all, nights. Fortunately enough, my company didn't fire me; instead they gave me the opportunity to learn and work as a web programmer. Since then, in less than a year, I've had to learn Java, JavaScript, JSTL, EL, JSP, regular expressions, Spring, Hibernate, SQL, etc. And, you know what? I did. I'm not an expert, of course, but I'm really interested in continuing to learn. Is my new-born career a dead end, or do I have a chance of becoming good at programming?"

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

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

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.'"
