Today Apple announced a few expanded open source efforts. First, beginning with Mac OS X 10.4.7, the Darwin/Mac OS X kernel, known as "xnu", is again available as buildable source for the Intel platform, including EFI utilities. Second, iCal Server, Bonjour, and launchd are moving to Apache 2.0 licensing. And finally, Mac OS Forge has been launched, as the successor to OpenDarwin as a conduit for hosting projects such as WebKit that were formerly hosted by the OpenDarwin project's servers, such as WebKit. Mac OS Forge is sponsored by Apple. DarwinPorts has already moved to its own servers. Update: 08/08 01:43 GMT by J : The official Apple announcement is now out. Other fun news: Leopard will ship with Ruby on Rails.

rfreedman asks: "Most of the buzz on the web about software development tools, languages, and practices seems to concentrate on getting software developed as quickly as possible. Take, for example, the current huge hype about Ruby on Rails, and how it allows the creation of a CRUD web-database application x-times more quickly than every other environment. It seems to me that this concentration on initial construction of software ignores the issue of total cost of ownership. Most people who develop software also have to maintain it, and have to support changes to it over long periods of time. As has been discussed many times over the years, maintenance is the most expensive part of the software development life-cycle. I think that the software development community would be better served by discussions of how to build more robust, flexible, and maintainable software (thereby driving down TCO), than by the endless discussions that we currently see about how to build it quickly. What do you think?"

Simon P. Chappell writes "This may not be the book that you think it is, if you don't read the title carefully, but it is the book you need, if you are developing applications for Ruby On Rails (often known as just Rails, or RoR, to its friends). When learning any new development platform, there are many idioms and approaches, best practices if you will, that can benefit your development efforts. This book sets out to bring you that understanding of the best way to write the Ruby side of your Rails application." Read the rest of Simon's review.

An anonymous reader writes "The Java community has used JavaServer Pages (JSP) technology through most of the last decade, but signs of rust are starting to show. Longstanding conventions inhibit Java programmers from using Java code within Web pages now. Other languages handle Web development much better than Java. This article discuss how code generation works in Ruby, and it delve into a more radical component-based approach in Seaside."

rdelon writes "Finally there is some movement in the hosting provider control panel department. cPanel and Ensim have been around for years but some people have grown increasingly frustrated with them. WebFaction has developed a new type of control panel. It offers an Ajax web interface that decouples the application from the domain: the root of a website might be served by Ruby on Rails while the /blog URL might be served by WordPress; reciprocally, multiple websites might be served from a single Django application, which reduces the resource usage on the server. A screencast demo of the control panel is available on their blog."

An anonymous reader writes "Ruby on Rails seems to be the new hotness in the world of web development, right up there with Ajax. IBM DeveloperWorks has a helpful howto on how to bring the worlds of Ruby on Rails and your DB2 framework together. From the article: 'Because Rails emerged from the open source world, until recently you had to use MySQL or PostgreSQL to work with it. Now that IBM has released a DB2 adapter for Rails, it's possible to write efficient Web applications on top of your existing DB2 database investment.'"

markmcb asks: "I help design a LAMP web site and I'm constantly plagued by trying to decide on what level should I separate functional code and markup. Depending on what you read, some say embedding HTML in your PHP scripts [or Perl, or Java, or Ruby, or Python, etc] is bad while others say it's no big deal. However, seldom are any practical applications of such code cited. How is your site built? Do you mix HTML with your code? If not, how do you overcome the simple and easy method of doing so? Lastly, what performance gains/losses have you noticed by doing so?"

An anonymous reader writes "Ruby on Rails seems to be a lightning rod for controversy. At the heart of most of the controversy lies amazing productivity claims. Rails isn't a better hammer; it's a different kind of tool. This article explores the compromises and design decisions that went into making Rails so productive within its niche."

Aranth writes "The staff at Ars Technica has gotten its hands on a demo of Duke Nukem Forever, and has written up a review. It seems the game is near ready for release! As the article explains, the reason it has taken so long to develop is because this is the first real Web 3.0 application- it has 'been rewritten as an Ajax application written using the Ruby on Rails framework' and runs in any web browser, although some seem to have difficulties." Sadly, the game looks to be deficient in the area of ponies. :(((( But, it's playable from my hiptop!! :))))

MrByte420 writes "The Ruby On Rails team today released version 1.1 of the web framework. From the announcement: 'Rails 1.1 boasts more than 500 fixes, tweaks, and features from more than 100 contributors. Most of the updates just make everyday life a little smoother, a little rounder, and a little more joyful.' New features were examined back in February at Scottraymond.net and include Javascript/AJAX integration, enhancements to active record, and enhanced testing suites. Not to mention upgrading this time promises to be a piece of cake."

At the beginning of this month we sent your questions to Isam Bayazidi of Amman, Jordan. He's a Slashdot reader, founder of the Jordan Planet blogging community, and (I know this from personal experience) knows the best places to buy discount-priced computer components in his home town. Enjoy!

Michael J. Ross writes "To modify a digital image, most computer users turn to a GUI-based image processing application, such as Photoshop. However, while Photoshop and many other similar programs can process multiple images in batch mode, they still require manual usage, and thus typically are unable to process images via a command line or within a second application. Those capabilities call for a programmatic digital image manipulation tool such as ImageMagick, which is explored in a relatively new book, The Definitive Guide to ImageMagick." Read the rest of Michael's review.

An anonymous reader writes "Everyone knows that no programming language is a perfect fit for every job. This article launches a 'new series by Bruce Tate that looks at ways other languages solve major problems and what those solutions mean to Java developers. He first explores Active Record, the persistence engine behind Ruby on Rails.'"

bonch writes "Apple has noticed the high amount of Mac usage in the Ruby on Rails community and has posted an illustrated Ruby on Rails tutorial. The document goes into more concise detail in getting new users up to speed, from database schema to moving beyond scaffolding, all done with the favored Rails editor, Textmate."

RMX asks: "In our company, we're currently going through the debate of standardizing on a computer language for our next set of products. The pro-standardization guys say that a single language (like Java) will save everyone time. The anti-standardization guys are advocating a mixed environment (of languages like Python, Ruby, and C#), and argue that the whole discussion is as silly as a manufacturing firm standardizing on screwdrivers for all their screw/nail/glue fastening needs. Have any of your companies standardized on a language? How well did it go?"

constab writes "ActiveState, the Sophos-owned company that makes free distributions and commercial programming tools for programming languages like Perl, Python, PHP, Tcl and Ruby, has been sold to a Canadian VC firm. According to the article, ActiveState will go back to its open-source roots and continue development of ActivePerl, ActivePython and ActiveTcl. A full set of Mac OS X on Intel downloads is also in the works."

Anml4ixoye writes "I recently got sent a copy of Bruce Tate's newest book Beyond Java - A Glimpse at the Future of Programming Languages. Having read Bruce's Bitter Java and Better, Faster, Lighter Java, I was intrigued to see what he would have to say about moving beyond Java. In short: If you're a hard-core Java (or to a lesser extent, C#) developer who thinks Ruby is something that goes on a ring, Pythons will bite you, and Smalltalk is something you have to do at parties, you are in for a rude awakening."

USA Today has a piece up talking with the writers of Smartbomb about the greater significance of gaming in the here and now. From the article: "In 2002, the military released America's Army, a game designed to inspire young men and women gamers to join the army. Within one year, it was registered by 2.4 million people and nominated for an award by a top gaming organization. It was a blockbuster. America's Army, along with a game used to train recruits and a sci-fi, holodeck knockoff (a room that allows the participant to see, feel and smell a virtual environment), will be used to 'train soldiers for the emotional experience' of war, making up a part of the U.S. military's new DNA, according to Chaplin and Ruby."

An anonymous reader writes "IBM DeveloperWorks has an interesting writeup on Ruby that takes a look at the programming language as a stand-alone solution rather than defining it in terms of Rails. From the article: 'Ruby on Rails is just one facet of what makes Ruby great, just like EJB is only part of the Java enterprise platform. Andrew Glover digs beneath the hype for a look at what Java developers can do with Ruby, all by itself. Ruby's syntax is quite different from that of the Java language, but it's amazingly easy to pick up. Moreover, some things are just plain easier to do in Ruby than they are in the Java language.'"

TomH writes "Bruce Eckel has an article at Aritma, where he posits that 'The Java hyper-enthusiasts have left the building, leaving a significant contingent of Java programmers behind, blinking in the bright lights without the constant drumbeat of boosterism.' Has the previous hype of Java and J2EE moved on to Ruby (on Rails) and Python?"
