Multiple Security Holes In Ruby 1.8, 1.9 148

ruphus13 notes a six-pack of serious vulnerabilities discovered in Ruby by a member of Apple's security team, Drew Yao. Patches are linked from the ruby-lang.org advisory. "With the following vulnerabilities, an attacker can lead to denial of service condition or execute arbitrary code... These vulnerabilities are likely to crop up in just about any average ruby web application. And by 'crop up' I mean 'crop up exploitable from trivial user-specified parameters.' It's not hard to begin imagining cases where Ruby/Rails programmers use code similar to the samples above to routinely handle user input."

Apple's SproutCore, OSS Javascript-Based Web Apps 203

99BottlesOfBeerInMyF writes "AppleInsider is running an article about Apple's new SproutCore Web application development framework, utilizing Javascript and some nifty HTML 5 to offer a 'Cocoa-inspired' way to create powerful Web applications. Apple built on the OSS SproutIt framework developed for an online e-mail manager called 'Mailroom.' Apple used this framework to build their new Web application suite (replacing .Mac) called MobileMe. Since SproutCore applications rely on JavaScript, it seems Apple had good reason to focus on Squirrelfish for faster JavaScript interpretation in Webkit. Apple hosted a session last Friday at WWDC introducing SproutCore to developers, but obviously NDAs prevent developers from revealing the details of that presentation. Apple has a chance here to keep the Web becoming even more proprietary as Silverlight and Flash battle it out to lock the Web application market into one proprietary format or another. Either way, this is a potential alternative, which should make the OSS crowd happy." TechDIrt's writeup on the browser evolving towards acting as an OS expands on the theme AppleInsider raises.

Move Over AJAX, Make Room for ARAX 409

sasserstyl writes "eWeek reports that Microsoft's Silverlight platform will support Ruby client-side scripting, enabling ARAX — or Asynchronous Ruby and XML. Would be cool to have the option to script client-side in something other than Javascript. 'In essence, using ARAX, Ruby developers would not have to go through the machinations of using something like the RJS (Ruby JavaScript) utility, where they write Ruby code and RJS generates JavaScript code to run on the client, Lam said. "Sure, you could do it that way, but then at some point you might have to add some JavaScript code that adds some custom functionality on the client yourself," he said. "So there's always that sense of, 'Now I'm in another world. And wouldn't it be nice if I have this utility class I wrote in Ruby...' Today if I want to use it in the browser I have to port it to JavaScript. Now I can just run it in the browser."'"

Microsoft Linking Silverlight, Ruby on Rails 232

CWmike writes "Friday Microsoft will demonstrate integration between its new Silverlight browser plug-in and Ruby on Rails. Microsoft's John Lam, a program manager in the dynamic language runtime team, said in a recent blog item: 'Running Rails shows that we are serious when we say that we are going to create a Ruby that runs real Ruby programs. And there isn't a more real Ruby program than Rails.' Also at the event, Microsoft officials will demonstrate IronRuby, a version of the Ruby programming language for Microsoft's .Net platform, running a Ruby on Rails application."

MagLev, Ruby VM on Gemstone OODB, Wows RailsConf 132

murphee ends along a report from InfoQ: "Gemstone demoed [MagLev,] their Ruby VM built on their GemStone S64 VM, to an ecstatic audience. Gemstone's Smalltalk VM allows OODBs of up to 17 PetaBytes, with none of the old ActiveRecord nonsense: the data is persisted transparently. The Gemstone OODB also takes care of any distribution, allowing the Ruby VM and data to scale across many servers (Cheerio, memcached!). There's also an earlier quite technical interview with Gemstone's Bob Walker and Avi Bryant about MagLev."

What Makes a Programming Language Successful? 1119

danielstoner writes "The article '13 reasons why Ruby, Python and the gang will push Java to die... of old age' makes an interesting analysis of the programming languages battling for a place in programmers' minds. What really makes a language popular? What really makes a language 'good'? What is success for a programming language? Can we say COBOL is a successful language? What about Ruby, Python, etc?"

The Definitive ANTLR Reference 95

Joe Kauzlarich writes "Finally, someone has done us all the great service of publishing a book about the second most well-known compiler compiler, Terence Parr's Antlr, and it was written, moreover, by Parr himself and published as part of the somewhat-usually-reliable Pragmatic Bookshelf series. Take note, while it requires a JVM to run, Antlr is not just for Java developers; it generates compilers in Python, Ruby, C, C++, C# and Objective-C. Also note that this book is more than just an elaborated man-page; it is also an excellent introduction to the concepts of compiler and parser design." Keep reading for the rest of Joe's review.

Picking the Right Eclipse Distribution 78

Someone over at IBM Developerworks who prefers anonymity writes "Depending on what you want to do, there is probably a commercial or free distro built on the Eclipse platform waiting for you. From C/C++, Ruby, PHP, Groovy, Java, and Web development, you can use an IDE built on Eclipse to help you. The big question is: Which Eclipse distribution is right for you?"

Practical Rails Projects 65

Sean Cribbs writes "There are many beginning and advanced Ruby on Rails books available, from the authoritative Agile Web Development with Rails to the cookbook-style Rails Recipes. However, healthy guidance for intermediate-level developers is lacking at best. Ironically, this is the most crucial stage in the process of becoming proficient with Rails because one must begin to learn why, not just how. Eldon Alameda's Practical Rails Projects effectively fills that gap. I know Alameda from our local Ruby User Group and spoke with him frequently while he wrote this book. His expertise with Rails definitely shines through in the hefty 621-page volume." Keep reading for the rest of Sean's review.

Twitter Reportedly May Abandon Ruby On Rails 423

Raster Burn writes "According to TechCrunch, Twitter has plans to abandon Ruby on Rails after two years of scalability issues. Candidates to replace Rails are said to be PHP, Java, and Ruby without the Rails framework." The post links a brief comment (at 139 characters, probably a tweet) from Twitter founder Ev Williams saying it ain't so. The comments following the post embody the controversy over whether or not RoR sucks.

Ruby and Java Running in JavaScript 220

John Resig is reporting on his blog that a recent trip to Tokyo opened up some very interesting JavaScript projects to him that haven't met with widespread popularity outside of Japan yet. "One project, in particular, really caught my eye. It's called Orto and is an implementation of the Java Virtual Machine (JVM) in JavaScript. This means that you can take an existing Java application, compile it to bytecode, run it through Orto (which produces the JavaScript, and embed it in a web page. While it doesn't provide the full capabilities of most Java code it does provide enough to make for some interesting demos." In a separate post he also detailed how the HotRuby project is allowing a Ruby VM to run in a browser using JavaScript or even indirectly using ActionScript in Flash.

Regular Expression Pocket Reference 144

Michael J. Ross writes "When software developers need to manipulate text programmatically — such as finding all substrings within some text that match a particular pattern — the most concise and flexible solution is to use "regular expressions," which are strings of characters and symbols that can look anything but regular. Nonetheless, they can be invaluable for locating text that matches a pattern (the "expression"), and optionally replacing the matched text with new text. Regular expressions have proven so popular that they have been incorporated into most if not all major programming languages and editors, and even at least one Web server. But each one implements regular expressions in its own way — which is reason enough for programmers to appreciate the latest edition of Regular Expression Pocket Reference, by Tony Stubblebine."

What Programming Languages Should You Learn Next? 759

simoniker writes "Over at Dobbs Code Talk, Chris Diggins has been discussing programming languages beyond C++ or Java, suggesting options such as Ruby ('does a great job of showing how powerful a dynamic language can be, and leverages powerful ideas from Smalltalk, Perl, and Lisp') but suggesting Scala as a first choice ('Very accessible to programmers from different backgrounds.') What would your choice be for programmers extending beyond their normal boundaries?"

Advanced Rails 170

yukster writes "As Ruby on Rails rocketed into the development community's hearts and minds a few years ago, the number of books on the subject climbed with it. However, a lot of these books were introductory in nature (Agile Web Development with Rails, Beginning Rails, Build Your Own Rails Applications, etc.). What's a budding Rails-head to do once they've gotten the basics down? Books like Advanced Rails, which was released late last year by O'Reilly, aim to fill this void."

The Ruby Programming Language 172

bdelacey writes "In January 2008, just in time for Ruby's 15th birthday, O'Reilly published The Ruby Programming Language. The co-authors make a strong writing team. Yukihiro (Matz) Matsumoto created Ruby. David Flanagan previously wrote Java In a Nutshell and JavaScript: The Definitive Guide — he has a CS degree from MIT with a concentration in writing. Drawings are the work of Rubyist-extraordinaire why the lucky stiff and technical reviewers include well known Rubyists David A. Black, Charles Oliver Nutter, and Shyouhei Urabe."

Rails May Not Suck 160

KDan writes "With astonishing regularity, articles or posts come out claiming that the popular Ruby on Rails framework sucks in some way or another. People complain that Rails isn't as easy to deploy as PHP, that Rails just didn't do it for project XYZ. They range from the articulate and well thought out to the frankly inane and stupid (and wrong). Recently, there's also of course been the spectacular nuclear rant by Zed Shaw, which was more a rant against random elements of the community than against Rails, but was still presented as a rant against Rails. Here's an article that tries to put some perspective on why these opinions are irrelevant to whether or not Rails sucks."

Rails Bigwig Rails on Rails Community 616

Zed Shaw, creator of the popular Mongrel HTTP daemon / library, has decided it was high time to tear into the Ruby/Rails community for many different complaints that he has been collecting over the last few years. "Rails is a Ghetto" is Shaw's self-proclaimed exit strategy from the Rails community. "This is that rant. It is part of my grand exit strategy from the Ruby and Rails community. I don't want to be a 'Ruby guy' anymore, and will probably start getting into more Python, Factor, and Lua in the coming months. I've got about three or four more projects in the works that will use all of those and not much Ruby planned. This rant is full of stories about companies and people who've either pissed in my cheerios somehow or screwed over friends. I can back all of them up from emails, IRC chat logs, or with witnesses. Nothing in here is a lie unless it's really obviously a lie through exaggeration, and there's a lot of my opinion as well."
