kang327 writes "As Java developers we are used to the familiar file-based user interface that is used by all of the major IDEs. A team at Brown University has developed an IDE for Java called Code Bubbles that makes a fairly radical departure from current IDEs — it is based on fragments instead of files. The idea is that you can see many different pieces of code at once. Fragments can form groups, have automatic layout assistance, wrap long lines based on syntax, and exist in a virtual workspace that you can pan. A video shows reading and editing code, opening different kinds of info such as Javadocs, bug reports and notes, annotating and sharing workspaces, and debugging with bubbles. They report on several user studies that show the system increases performance for the tasks studied, and also that professional developers were enthusiastic about using it. There is also a Beta that you can sign up for."

snydeq writes "Peter Wayner provides a developer's comparison of Android and the iPhone and finds Android not only competitive but in fact a better choice than the iPhone for many developers, largely due to its Java foundation. 'While iPhone developers have found that one path to success is playing to our baser instincts (until Apple shuts them down), a number of Android applications are offering practical solutions that unlock the power of a phone that's really a Unix machine you can slip into your pocket,' Wayner writes, pointing out GScript and Remote DB as two powerful tools for developers to make rough but workable custom tools for Android. But the real gem is Java: 'The pure Java foundation of Android will be one of the biggest attractions for many businesses with Java programmers on the staff. Any Java developer familiar with Eclipse should be able to use Google's Android documentation to turn out a very basic application in just a few hours. Not only that, but all of the code from other Java programs will run on your Android phone — although it won't look pretty or run as fast as it does on multicore servers.'"

MyNoSQL has up an interview with Ryan King on how Twitter is transitioning to the Cassandra database. Here's some detailed background on Cassandra, which aims to "bring together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model." Before settling on Cassandra, the Twitter team looked into: "...HBase, Voldemort, MongoDB, MemcacheDB, Redis, Cassandra, HyperTable, and probably some others I'm forgetting. ... We're currently moving our largest (and most painful to maintain) table — the statuses table, which contains all tweets and retweets. ... Some side notes here about importing. We were originally trying to use the BinaryMemtable interface, but we actually found it to be too fast — it would saturate the backplane of our network. We've switched back to using the Thrift interface for bulk loading (and we still have to throttle it). The whole process takes about a week now. With infinite network bandwidth we could do it in about 7 hours on our current cluster." Relatedly, an anonymous reader notes that the upcoming NoSQL Live conference, which will take place in Boston March 11th, has announced their lineup of speakers and panelists including Ryan King and folks from LinkedIn, StumbleUpon, and Rackspace.

Niris writes "I'm currently taking a course called Advanced Java Programming, which is using the text book Absolute Java, 4th edition, by Walter Savitch. As I work at night as a security guard in the middle of nowhere, I've had enough time to read through the entire course part of the book, finish all eleven chapter quizzes, and do all of the assignments within a month, so all that's left is a group assignment that won't be ready until late April. I'm trying to figure out what else to read that's Java related aside from the usual 'This is how to create a tree. This is recursion. This is how to implement an interface and make an anonymous object,' and wanted to see what Slashdotters have to suggest. So far I'm looking at reading Beginning Algorithms, by Simon Harris and James Ross."

Barence writes "How good — or bad — are fake iPhones? PC Pro blogger Steve Cassidy has a friend who paid £25 ($40) for an 'iPhone' in a bar, and he's got the photos and full lowdown of what's inside this not-so smartphone. The phone looks convincing enough from the outside, with a genuine-looking backplate, but things start to go wrong when you switch it on. What's a "Java" and "WLAN" App button doing on the screen? And how about that Internet Explorer icon? It's like you're handling an artefact from an alternate history, dropped in via a spacetime wormhole. It has dual SIM handling, too, and came with a bizarre auxiliary battery festooned with warnings about not pressing a button mounted on the front of the top-up device."

Andy Updegrove writes "A short while ago the parties to one of the most closely watched FOSS cases filed a settlement agreement with the US Federal District Court for the Northern District of California ending one of the most important F/OSS legal cases to date. That case is Jacobsen vs. Katzer, and the settlement marks a complete victory for Jacobsen, a member of the Java Model Railroad Interface (JMRI) Project. Jacobsen's victory establishes several important rights for the first time in the US: the right to prevent their copyright and authorship acknowledgments from being removed from their code, and the right to collect damages if the terms of the licenses they choose are violated. Until now, those rights had never been tested in court."

BeardedChimp writes "I, like many others here, have learned to program by myself. Starting at a young age and learning through fiddling I have taught myself C++, Java, python, PHP, etc., but what I want to know is what I haven't learned that is important when taught in a traditional computer science curriculum. I have a degree in physics, so I'm not averse to math. What books, websites, or resources would you recommend to fill in the gaps?"

Ian Lamont writes "InfoWorld has an interesting analysis of the reasons behind the relative dearth of programmers over the age of 40. While some people may assume that the recession has provided a handy cover for age discrimination, a closer look suggests that it's the nature of IT itself to push its elderly workers out, in what the article describes as a 'Logan's Run'-like marketplace. A bunch of factors are listed as reasons, including management's misunderstanding of the ways in which developers work: 'Any developer can tell you that not all C or PHP or Java programmers are created equal; some are vastly more productive or creative. However, unless or until there is a way to explicitly demonstrate the productivity differential between a good programmer and a mediocre one, inexperienced or nontechnical hiring managers tend to look at resumes with an eye for youth, under the "more bang for the buck" theory. Cheaper young 'uns will work longer hours and produce more code. The very concept of viewing experience as an asset for raising productivity is a non-factor — much to the detriment of the developer workplace.'"

FrazzledDad writes "'We let the tests we wrote do more harm than good.' That snippet from the preface of Roy Osherove's The Art of Unit Testing with Examples in .NET (AOUT hereafter) is the wrap up of a frank description of a failed project Osherove was part of. The goal of AOUT is teaching you great approaches to unit testing so you won't run into similar failures on your own projects." Keep reading for the rest of FrazzledDad's review.

Precision writes to inform us about the Swiss firm Myriad, which claims a 3x boost in Android app performance and longer battery life with a new virtual machine. Myriad says that its technology is 100% compatible with existing Android apps. "The tool is a replacement for the Dalvik virtual machine, which ships as part of the Android platform, and retains full compatibility with existing software. Dalvik Turbo also supports a range of processors including those based on ARM, Intel Atom, and MIPS Architectures."

sproketboy writes "Project Darkstar, an open source software platform from Sun labs that simplifies the development of horizontally scalable servers for online games, is being discontinued as of the Oracle acquisition. This project, mentioned a couple of years back on Slashdot, was a unique concept for building an application server specific to on-line gaming. Sadly they were so close at version 0.9.11 (which is still very stable). Hopefully the open source community can get involved and help continue work on this project."

krebsonsecurity writes "The Web browser wars often focus on which browser is more secure, but the dirty secret is that insecure plugins are a serious threat to all browsers, from the perspectives of both stability and security. Krebsonsecurity.com features an informative look at the administration page for a popular browser exploit kit called Eleonora, which suggests that plugins like Adobe Reader and Java are leading to successful compromises for users surfing not just with Internet Explorer, but also with Google Chrome, Firefox, Safari, and Opera."

rubycodez writes "The anti-trust body of the EU, the European Commission, has approved Oracle's acquisition of Sun Microsystems, believing competition would be preserved. It saw PostgreSQL as a viable independent alternative to MySQL and that market access to Java would not be restricted. Uncertainty about Sun's future has cost over a billion dollars in lost sales in the past year."

thelordx writes "I've got a much younger brother who I'd like to teach how to program. When I was younger, you'd often start off with something like BASIC or Apple BASIC, maybe move on to Pascal, and eventually get to C and Java. Is something like Pascal still a dominant teaching language? I'd love to get low-level with him, and I firmly believe that C is the best language to eventually learn, but I'm not sure how to get him there. Can anyone recommend a language I can start to teach him that is simple enough to learn quickly, but powerful enough to do interesting things and lead him down a path towards C/C++?"

cyclocommuter writes with this snippet from The Register's assessment of whether Microsoft's .NET framework has been a success: "If the goal of .NET was to see off Java, it was at least partially successful. Java did not die, but enterprise Java became mired in complexity, making .NET an easy sell as a more productive alternative. C# has steadily grown in popularity, and is now the first choice for most Windows development. ASP.NET has been a popular business web framework. The common language runtime has proved robust and flexible. ... Job trend figures here show steadily increasing demand for C#, which is now mentioned in around 32 per cent of UK IT programming vacancies, ahead of Java at 26 per cent."

adeelarshad82 writes "Truly open-development, open-source phones like the Nokia N900 will never hit the mainstream in the US because wireless carriers in the country hate the unexpected, writes PCMag's Sascha Segan. The open-source philosophy is all about unexpected, disruptive ideas bubbling upwards, and that drives network planners nuts. So, you get unsatisfactory hybrids like Google Android, which uses some open-source components but locks third-party developers into a crippled Java sandbox. The bottom line is that while Linux the OS, the kernel, and the memory manager are attractive to phone manufacturers, Linux the philosophy — and users banding together ad hoc to create new things — is anathema to wireless carriers."

Martijn de Boer writes "The book has been written to provide the reader with a short introduction to the concepts of Service Oriented Architecture with Java. The book covers the theory and analysis from the start and is progressing to a more intermediate level slowly throughout the different chapters. This book has been written for software architects and programmers of the Java language who have an interest in building software using SOA concepts in their applications. The cover hints to a series called “From Technologies to Solutions”, and that is exactly what this book tries to do, it tries to explain the SOA technology with different case studies and a path for solutions for your applications." Read below for the rest of Martijn's review.

Many readers are sending in the news about Go, the new programming language Google has released as open source under a BSD license. The official Go site characterizes the language as simple, fast, safe, concurrent, and fun. A video illustrates just how fast compilation is: the entire language, 120K lines, compiles in under 10 sec. on a laptop. Ars Technica's writeup lays the stress on how C-like Go is in its roots, though it has plenty of modern ideas mixed in: "For example, there is a shorthand syntax for variable assignment that supports simple type inference. It also has anonymous function syntax that lets you use real closures. There are some Python-like features too, including array slices and a map type with constructor syntax that looks like Python's dictionary concept. ... One of the distinguishing characteristics of Go is its unusual type system. It eschews some typical object-oriented programming concepts such as inheritance. You can define struct types and then create methods for operating on them. You can also define interfaces, much like you can in Java. In Go, however, you don't manually specify which interface a class implements. ... Parallelism is emphasized in Go's design. The language introduces the concept of 'goroutines' which are executed concurrently. ... The language provides a 'channel' mechanism that can be used to safely pass data in and out of goroutines."

An anonymous reader writes to tell us that a recent FAQ released by Oracle outlines the plans for many of Sun's popular products like GlassFish, MySQL, and NetBeans. Many are worried at some of the possible avenues the decisions outlined could lead to, especially with respect to NetBeans. "What should have happened, Oracle should not have missed a beat and should have announced work on Oracle plugins for NetBeans and active Oracle support of NetBeans. This type of announcement would have brought a large and some-what skeptical NetBeans community much closer to Oracle. It would have been a big win for Oracle. NetBeans will continue to grow either way - but Oracle has missed a big chance to really change perceptions and at the same time move their tools to another level. What JDeveloper lacks is buzz, a wealth of community developed plugins, a wealth of support for other languages and a very, very large community. And of course it does not offer a platform in the NetBeans and Eclipse sense of the word. This is a huge missed opportunity for Oracle."

54mc writes "Crunchgear reports that Microsoft's long-searched-for forensics tool, COFEE, has been leaked. The tool started on a small, private tracker, but has since worked its way to The Pirate Bay. Not all those who have gotten hold of it are enthused, and reviews have ranged from 'disappointing' to 'useless.' From the article: 'You have absolutely no use for the program. It's not something like Photoshop or Final Cut Pro, an expensive application that you download for the hell of it on the off-chance you need to put Dave Meltzer's face on Brett Hart's body as part of a message board thread. No, COFEE is 100 percent useless to you.'"
