Janwedekind writes "Yuki Sonoda yesterday announced the release of Ruby 1.9.1 (Ruby Inside coverage with lots of links). The VM of Ruby 1.9, formerly known as YARV, was initiated by Koichi Sasada and has been in the making for quite some time. Ruby's creator Yukihiro Matsumoto has already presented many of the upcoming features in his keynote at RubyConf 2007. Most notably, Ruby 1.9 now supports native threads and an implementation of fibers. A lot of work also went into encoding awareness of strings. The 1.9.1 version is said to be twice as fast as the stable 1.8.7. It will take some time though until the majority of existing Ruby extensions get ported to 1.9."

svonkie writes "C overwhelmingly proved to be the most popular programming language for thousands of new open-source projects in 2008, reports The Register (UK). According to license tracker Black Duck Software, which monitors 180,000 projects on nearly 4,000 sites, almost half — 47 per cent — of new projects last year used C. 17,000 new open-source projects were created in total. Next in popularity after C came Java, with 28 per cent. In scripting, JavaScript came out on top with 20 per cent, followed by Perl with 18 per cent. PHP attracted just 11 per cent, and Ruby six per cent. The numbers are a surprise, as open-source PHP has proved popular as a web-site development language, while Ruby's been a hot topic for many."

markmcb writes "A year ago my company began using SAP as its ERP system, and there is still a great deal of focus on cleaning up the 'master data' that ultimately drives everything the system does. The issue we face is that the master data set is gigantic and not easy to wrap one's mind around. As powerful as SAP is, I find it does little to aid with useful visualization of data. I recently employed a custom solution using Ruby and Graphviz to help build graphs of master data flow from manual extracts, but I'm wondering what other people are doing to get similar results. Have you found good out-of-the-box solutions in things like data warehouses, or is this just one of those situations where customization has to fill a gap?"

rye writes in to recommend a Sherri Davidoff interview with Matt Knox, a talented Ruby instructor and coder, who talks about his early days designing and writing adware for Direct Revenue. (Direct Revenue was sued by Eliot Spitzer in 2006 for surreptitiously installing adware on millions of computers.) "So we've progressed now from having just a Registry key entry, to having an executable, to having a randomly-named executable, to having an executable which is shuffled around a little bit on each machine, to one that's encrypted — really more just obfuscated — to an executable that doesn't even run as an executable. It runs merely as a series of threads. ... There was one further step that we were going to take but didn't end up doing, and that is we were going to get rid of threads entirely, and just use interrupt handlers. It turns out that in Windows, you can get access to the interrupt handler pretty easily. ... It amounted to a distributed code war on a 4-10 million-node network."

markmcb writes "My development team was recently brainstorming over finding a practical solution to the problem that's haunted anyone who's ever used a framework: convention vs. customization. We specifically use Rails, and like most frameworks, it's great for 95% of our situations, but it's creating big bottlenecks for the other 5%. Our biggest worry isn't necessarily that we don't know how to customize, but rather that we won't have the resources to maintain customized code going forward; it's quite simple to update Rails as it matures versus the alternative. What have your experiences been with this problem? Have you found any best practices to avoid digging custom holes you can't climb out of?"

An anonymous reader writes "The Merb and Rails Core Teams today announced a major merger; the two projects will become one, and be released some time in Q2 of 2009 as Rails 3. This is great news for lots of folks who worried about the potential community fracture, as well as great news for all the developers who will now have an all-around better option for programming Ruby. Read more about the details in Yehuda's blog post, or at the Ruby on Rails blog."

firthisaword writes "I will be teaching an enrichment programming course to 11-14 year old gifted children in the Spring. It is meant as an introduction to very basic programming paradigms (conditions, variables, loops, etc.), but the kids will invariably have a mix of experience in dealing with computers and programming. The question: Which programming language would be best for starting these kids off on? I am tempted by QBasic which I remember from my early days — it is straightforward and fast, if antiquated and barely supported under XP. Others have suggested Pascal which was conceived as an instructional pseudocode language. Does anyone have experience in that age range? Anything you would recommend? And as a P.S: Out of the innumerable little puzzles/programs/tasks that novice programmers get introduced to such as Fibonacci numbers, primes or binary calculators, which was the most fun and which one taught you the most?" A few years ago, a reader asked a similar but more general question, and several questions have focused on how to introduce kids to programming. Would you do anything different in teaching kids identified as academically advanced?

An anonymous reader writes "Zen and the Art of Programming published a new version of The Great Ruby Shootout, which was aimed at testing the performances of multiple Ruby implementations. On the benchmark table this time around are Ruby 1.8 (on GNU/Linux and Windows), Ruby 1.9 (aka Yarv), Ruby Enterprise Edition (aka REE), JRuby 1.1.6RC1, Rubinius, MagLev, MacRuby 0.3 and IronRuby. The results of this comprehensive comparison show that for this set of benchmarks, Ruby 1.9.1 is almost 5 times faster than the notoriously slow Ruby 1.8. Is Ruby finally going to be acceptably fast?"

jamie pointed out an important announcement in the Perl community. Adam Kennedy, known as Alias, developed Strawberry Perl to "make Win32 a truly first class citizen of the Perl platform world." Over the last year, major CPAN modules have used Strawberry Perl to get to releases that work trouble-free on Windows. But the tens of thousands of smaller modules on CPAN are lagging, in many cases because of lack of access to a Windows environment for development and testing. Now Alias has worked with Microsoft's Open Source Software Lab to provide for every CPAN author free access to a centrally-hosted virtual machine environment containing every major version of Windows. "More information (and press releases) will follow, the entire program under which this partnership will be run is so new it's only just been given a name, so some of the organisational details will ironed out as we go. But for now, to all the CPAN authors, all I have to add is... Merry Christmas. P.S. Or your appropriate equivalent religious or non-religious event, if any, occurring during the month of December, etc., etc."

synodinos writes "Ola Bini, a core JRuby developer and author of the book Practical JRuby on Rails Projects, has been developing a new language for the JVM called Ioke. This strongly typed, extremely dynamic, prototype-based, object-oriented language aims to give developers the same kind of power they get with Lisp and Ruby, combined with a nice, small, regular syntax."

An anonymous reader writes "After attending DEFCON in August and seeing the overwhelming interest in this book, I was eager to dive into The IDA Pro Book by Chris Eagle. Chris Eagle's team, School of Root, won the 'Capture the Flag' event at DEFCON this year and Chris gave a presentation on CollabREate, a tool that integrates with IDA Pro to allow collaboration in reverse engineering (RE). All of that — together with the fact that the book sold out — screamed that this book should quickly make it to the top of my list." This review originally appeared on The Ethical Hacker Network.

Esther Schindler writes "Several weeks ago, Lynn Greiner's article on the state of the scripting universe was slashdotted. Several people raised their eyebrows at the (to them) obvious omissions, since the article only covered PHP, Perl, Python, Ruby, Tcl and JavaScript. As I wrote at the time, Lynn chose those languages because hers was a follow-up to an article from three years back. However, it was a fair point. While CIO has covered several in depth, those five dynamic languages are not the only ones developers use. In 6 Scripting Languages Your Developers Wish You'd Let Them Use, CIO looks at several (including Groovy, Scala, Lua, F#, Clojure and Boo) which deserve more attention for business software development, even if your shop is dedicated to Java or .NET. Each language gets a formal definition and then a quote or two from a developer who explains why it inspires passion."

snydeq writes "InfoWorld examines the platforms and passions underlying today's popular dynamic languages, and though JavaScript, Perl, PHP, Python, Ruby, Groovy, and other scripting tools are fast achieving the critical mass necessary to flourish into the future, 10 forces in particular appear to be driving the evolution of this development domain. From the cooption of successful ideas across languages, to the infusion of application development into applications that are fast evolving beyond their traditional purpose, to the rise of frameworks, the cloud, and amateur code enablers, each will have a profound effect on the future of today's dynamic development tools."

riverman writes "I have been 'provisioned' at the school where I work to teach a new Computer Science/Programming course. I'm supposed to be teaching everything from the very-very basics (i.e. where that myspace thing is in your computer monitor, and how it knows who your friends are) to the easy-advanced (i.e. PHP classes and Python/Google App Engine). I'm an experienced programmer, but I'm not sure where to start — I could easily assume that my students know something basic they don't. Are there any resources on the internet that could help me find a solid curriculum? What are your suggestions?" I'm sure many of us have gone through intro-level programming courses of some sort; what are some things your teacher or professor did that worked well, and what didn't work at all?

thbar writes "I had some fun analyzing my whole GMail account data with Mac OS X, Ruby and software called Tableau. I'd be curious to know if others did the same thing, and how they achieved it."

Howling writes "I've been a PHP programmer for a few years and after taking a trip through many sites Ive learned that www.php.net is probably the most complete source when looking for information/documentation. I have been trying to find similar sites for every other language (Java, perl or ASP, for instance) without equal success, though. I ask: what is the best documentation/reference site for your preferred programming language?"

Esther Schindler writes to tell us that Lynn Greiner has another look at the state of the scripting universe as a follow on to the same topic three years ago. Greiner talks to major players from each of the main scripting languages (PHP, Perl, Tcl, Python, Ruby, and Javascript) to find out the current status and where they are headed in the future. "The biggest change since 2005 has been the growth of richer Web applications that perform more of their computations in the browser using JavaScript. The demand for these applications has forced developers to learn and use JavaScript much more than before. There's also been a lot of interest in Ruby, another dynamic language, spurred by the release and growth of Ruby on Rails. As a result of these changes, many developers are becoming more comfortable with dynamic languages."

Anti-Globalism recommends a posting up at O'Reilly's ONLamp on reasons that some companies are turning away from Perl. "[In one company] [m]anagement have started to refer to Perl-based systems as 'legacy' and to generally disparage it. This attitude has seeped through to non-technical business users who have started to worry if developers mention a system that is written in Perl. Business users, of course, don't want nasty old, broken Perl code. They want the shiny new technologies. I don't deny at all that this company (like many others) has a large amount of badly written and hard-to-maintain Perl code. But I maintain that this isn't directly due to the code being written in Perl. Its because the Perl code has developed piecemeal over the last ten or so years in an environment where there was no design authority.. Many of these systems date back to this company's first steps onto the Internet and were made by separate departments who had no interaction with each other. Its not really a surprise that the systems don't interact well and a lot of the code is hard to maintain."

Anonymous Hacker writes "I'm in a bit of a bind. My young teenage son is starting to get curious about computers, and in particular, programming. Now, I'm a long time kernel hacker (Linux, BSD and UNIX). I have no trouble handling some of the more obscure things in the kernel. But teaching is not something that I'm good at, by any means. Heck, I can't even write useful documentation for non-techies. So my question is: what's the best way to encourage his curiosity and enable him to learn? Now, I know there are folks out there with far better experience in this area than myself. I'd really appreciate any wisdom you can offer. I'd also be especially interested in what younger people think, in particular those who are currently in college or high school. I've shown my son some of the basics of the shell, the filesystem, and even how to do a 'Hello World' program in C. Yet, I have to wonder if this is the really the right approach. This was great when I was first learning things. And it still is for kernel hacking, and other things. But I'm concerned whether this will bore him, now that there's so much more available and much of this world is oriented towards point-n-click. What's the best way to for a young teen to get started in exploring this wonderful world of computers and learning how to program? In a *NIX environment, preferably." Whether or not you have suggestions for generating interest or teaching methods, there was probably something that first piqued your curiosity. It seems like a lot of people get into programming by just wondering how something works or what they can make it do. So, what caught your eye?

ruphus13 writes "Twitter has had a lot of public woes with Open Source technologies like Ruby on Rails, and a lot of alternatives have sprung up in the micro-blogging world, but no one has managed to dislodge twitter in its usage or appeal. Now, an Open Source alternative by Identi.ca, backed by project Laconica has emerged. From the article, 'It supports OpenID for logins, is completely free software, and is designed to apply a Creative Commons license to all the traffic that it carries. It's also built to support the OpenMicroBlogging protocol, meaning that (at least in theory) it can attack scalability issues by federating together multiple autonomous servers. The underpinnings of Laconica include PHP, PEAR, and XMPP. You can download a tarball of the source, or check it out directly if you're using Darcs (there's also an unofficial mirror on Google Code, giving you Subversion access for a read-only copy).' The community will still need to work on this, if a true competitor to Twitter is to emerge. It is lacking APIs, and SMS integration. Oh, and millions of users!"
