rheotaxis writes "Many professional web developers have spent years building dynamic, database-driven web applications, but some of us, like myself, want to make the user experience more interactive and instantaneous. The book Building the Realtime User Experience, by Ted Roden, is an introduction to some new techniques making that happen now. New web servers like Cometd and Tornado power solutions that keep HTTP connections open until data is available for the clients requesting it, a technique called 'long-polling.' This means web developers can provide a real-time user experience using HTTP for all sorts of client devices now connecting to the Internet, not just web browsers, but mobile devices as well."

javab0y writes "The folks over at basementcoders did a podcast with James Gosling, The Father of Java, last week at a coffee shop in San Francisco during the JavaOne conference. In a raw and no-holds-barred interview, James let loose on Oracle, the Google Lawsuit, and his experience with IBM. You know its going to be good when he starts out saying, 'I eventually graduated in '83. Went to work for IBM which is, you know, is within the top 10 of my stupidest career decisions I've made.' The podcast was fully transcribed."

mikesd81 writes "According to Gartner research firm, Google's Android smartphone operating system will in a single year have leapfrogged competitors like Apple's iPhone, Research in Motion's Blackberry and Microsoft Windows phones in global popularity, and will challenge Nokia to become the world's most popular mobile OS by 2014. Gartner says that the explosive growth of Android will give it 17.7% of world wide sales by the end of 2010. ... Analysts also say there are number of things that could derail Android's growth, including Oracle's lawsuit over Java patents."

snydeq writes "Citing concerns about Oracle's lawsuit against it, Google has backed out of the upcoming JavaOne conference. 'Oracle's recent lawsuit against Google and open source has made it impossible for us to freely share our thoughts about the future of Java and open source generally,' Google's Joshua Bloch said in a blog post. The move may signal eventual fragmentation for Java, with Google conceivably splintering off the Java-like language it uses for Android."

An anonymous reader writes "With Oracle suing Google over 'unofficial' support for Java in Android, Microsoft has come out and said it has no intention of taking action against the Mono implementation of C# on the Linux-based mobile OS. That's good news for Novell, which is in the final stages of preparing MonoDroid for release. Miguel de Icaza is not concerned about legal challenges by Microsoft over .Net implementations, and even recommends that Google switch from using Java. However, Microsoft's Community Promise has been criticized by the Free Software Foundation for not going far enough to protect open source implementations from patent litigation, which is at the heart of the Oracle-Google case."

An anonymous reader writes "In a lucid writeup, InfoWorld's Neil McAllister takes a different angle on the Oracle-Google lawsuit, giving an explanation why Oracle was right to sue Google. McAllister argues that Google is splintering the Java platform, just like Microsoft was doing back in the 90s, and should be held up to the same standards. He further cites Google's Josh Bloch calling for Oracle to take a lead role in steering Java, concluding that Bloch maybe 'should have been more careful what he wished for.'"

MBCook writes "Joa Ebert has started working on a new program called JITB. Announced in a talk at FITC San Fran, it's a Flash player written to use the Java JVM to run ActionScript, and in a simple graphics test case (making 1 million calls to flash.geom.Point) was 30x faster than Adobe's Flash player. There is an impressive demo video on YouTube showing the point test."

An anonymous reader writes "Though Microsoft had initially made a commitment to create versions of dynamic languages that are customized for .NET, recent reports make it clear that the company may be stepping back from this plan. Much early speculation on this change in focus comes from Jim Schementi, previously the program manager in charge of Microsoft's implementation of the Ruby software known as IronRuby. Schementi reports on his blog that the team dedicated to working on IronRuby has decreased to one employee. According to Schementi, his departure from the company came as Microsoft began to display a 'serious lack of commitment' to any .NETized dynamic languages, including IronRuby."

Bruce Perens writes "Oracle has brought a lawsuit against Google claiming that Google has infringed patents on the Java platform in Android. Scribd has a copy of the complaint. But there's a patent grant that should allow Google to use Java royalty-free. Has Google failed to meet the terms of the grant?"

DonLab writes "I was a proficient software engineer in the 1980s, writing hundreds of thousands of lines of ALGOL, FORTRAN, COBOL, and Pascal programs, as well as working in 370 and 8080 assembly language & pre-relational DBMS systems. My hands-on programming career ended when I became a freelance analyst and designer, ultimately retiring young in the early '90s. Now I'd like to reenter the field, but I'm finding that I know nothing about today's post-C languages, programming tools, and computing environments. I wouldn't know where to start learning C++, PHP, Java, HTML5, or PERL, much less how to choose one over the other for a particular application. Can I be the only pre-GUI software designer or hobbyist searching for a way to update his skills for Windows, iOS, or Android?"

CurtMonash writes "Nontechnical people — for example marketers or small business owners — increasingly get the feeling they should know more about technology. And they're right. If you can throw up a small website or do some real number-crunching, chances are those skills will help you feed your family. But how should they get started? I started a thread with the question on DBMS2, and some consistent themes emerged, including: Learn HTML + CSS early on; Learn a bit of SQL, but you needn't make that your focus; Have your first real programming language be one of the modern ones, such as PHP or Python; MySQL is a good vehicle to learn SQL; It's a great idea to start with a project you actually want to accomplish, and that can be done by modifying a starter set of sample code (e.g., a WordPress blog); Microsoft's technology stack is an interesting alternative to some of the other technology ideas. A variety of books and websites were suggested, most notably MIT's Scratch. But, frankly, it would really help to get more suggestions for sites and books that help one get started with HTML/CSS, or with MySQL, or with PHP. And so, techie studs and studdettes, I ask you — how should a non-techie go about learning some basic technological skills?"

crabel writes "In Java 1.6.0_21, the company field was changed from 'Sun Microsystems, Inc' to 'Oracle.' Apparently not the best idea, because some applications depend on that field to identify the virtual machine. All Eclipse versions since 3.3 (released 2007) until and including the recent Helios release (2010) have been reported to crash with an OutOfMemoryError due to this change. This is particularly funny since the update is deployed through automatic update and suddenly applications cease to work."

rsk writes "Paul Tyma, the man behind Mailinator, has put together an excellent performance analysis comparing old-school synchronous programming (java.io.*) to Java's asynchronous programming (java.nio.*) — showing a consistent 25% performance deficiency with the asynchronous code. As it turns out, old-style blocking I/O with modern threading libraries like Linux NPTL and multi-core machines gives you idle-thread and non-contending thread management for an extremely low cost; less than it takes to switch-and-restore connection state constantly with a selector approach."

snydeq writes "Google distinguished engineer Rob Pike ripped the use of Java and C++ during his keynote at OSCON, saying that these 'industrial programming languages' are way too complex and not adequately suited for today's computing environments. 'I think these languages are too hard to use, too subtle, too intricate. They're far too verbose and their subtlety, intricacy and verbosity seem to be increasing over time. They're oversold, and used far too broadly,' Pike said. 'How do we have stuff like this [get to be] the standard way of computing that is taught in schools and is used in industry? [This sort of programming] is very bureaucratic. Every step must be justified to the compiler.' Pike also spoke out against the performance of interpreted languages and dynamic typing."

Nushio writes "The code wasn't even released, and yet Roy van Rijn, a Music & Free Software enthusiast received a C&D from Landmark Digital Services, owners of Shazam, a music service that allows you to find a song, by listening to a part of it. And if that wasn't enough, they want him to take down his blog post (Google Cache) explaining how he did it because it 'may be viewed internationally. As a result, [it] may contribute to someone infringing our patents in any part of the world.'" Update: 07/09 00:31 GMT by T :Story updated to reflect that Shazam is multiplatform, not Android-only, as implied by the original phrasing.

RickJWagner writes "This is a book targeted primarily towards the Java programmer who doesn't yet know Groovy. Groovy is a dynamic scripting language that runs on the JVM and offers easy integration with the Java language. Groovy also offers dynamic language features that lend themselves to the creation of DSLs (Domain-Specific Languages). This book attempts to simultaneously teach the reader how to use Groovy and how to build a DSL." Keep reading for the rest of RickJWagner's review.

GMGruman writes "In an InfoWorld blog, Paul Krill suggests that those concerned that Java might get lost in Oracle's tangle of acquired technologies should relax a little: Java's future isn't wholly in Oracle's hands, so if Oracle screws up or lets Java languish, the popular language has other forces to move it forward nonetheless."

thisisauniqueid writes "In light of the clamor over the iPhone 4 Grip of Death, AnandTech recently reverse-engineered the phone's signal-strength-to-bars mapping. Because Android is open source, we can determine the corresponding mapping for Android in combination with the 3GPP spec referenced in the source, allowing the signal-strength-to-bars mapping for both Android and the iPhone 4 to be plotted on the same axes. This shows that the iPhone 4 consistently reports a higher percentage signal strength (as defined by the fraction of bars lit) than Android GSM devices at the same signal strength."

eldavojohn writes "The latest versions of Microsoft Windows have some good security options available — now if only they could get their most popular third-party applications to use them. A report from Secunia takes a look at two such options — DEP and ASLR — and Brian Krebs breaks down who is using them and who is not. A security specialist noted, 'If both DEP and ASLR are correctly deployed, the ease of exploit development decreases significantly. While most Microsoft applications take full advantage of DEP and ASLR, third-party applications have yet to fully adapt to the requirements of the two mechanisms (PDF). If we also consider the increasing number of vulnerabilities discovered in third-party applications, an attacker's choice for targeting a popular third-party application rather than a Microsoft product becomes very understandable.' Among those with neither DEP or ASLR: Apple Quicktime, Foxit Reader, Google Picasa, Java, OpenOffice.org, RealPlayer, and AOL's Winamp. While Flash player can't implement DEP, it does have ASLR. Google Chrome is the only popular third-party application listed with stars across the board." It's worth noting that several apps highlighted in the Secunia research paper have added support for those security options in recent patches, or are in the process of doing so. Examples include Firefox, VLC, and Foxit Reader.

DragonHawk writes "Mozilla Firefox 3.6.4 went to general release today. The big new feature in this release is out-of-process plugins (OOPP). This means things like Flash, Java, QuickTime, etc., all run in separate processes, so when Flash decides to crash, it won't take your browser out with it. If Flash starts consuming all the CPU it can find, you can kill it without nuking your browser session. I've been using this feature since it was in the 'nightly build' stage, and it was still more stable than 3.6.3, just because Flash was isolated." And reader Trailrunner7 supplies another compelling reason to download 3.6.4: "Security researcher Michal Zalewski has identified a problem with the way Firefox handles links that are opened in a new browser window or tab, enabling attackers to inject arbitrary code into the new window or tab while still keeping a deceptive URL in the browser's address bar. The vulnerability, which Mozilla has fixed in version 3.6.4, has the effect of tricking users into thinking that they're visiting a legitimate site while instead sending arbitrary attacker-controlled code to their browsers."
