Intel Demos Software Defined WiFi/WiMAX/DVB-H Chip 97

Doc Ruby writes "Electronics Weekly is reporting that Intel has developed a new prototype chip for software defined radio. The new chip will be able to handle WiFi, WiMAX and DVB-H digital TV all on the same chip. 'This kind of chip would allow equipment to access the WiFi network in the home, automatically handover to a WiMAX network when you leave the house and also access digital TV on the move, all through one chip.' It's also a proof that the entire class of SW radios that could possibly converge CDMA, GSM and various other radio networks for opportunistic handoffs by a single device, a 'universal radio' that could use content formerly locked into a single radio type."

BBC Creates 'Perl on Rails' 216

Bogtha writes "Long-time users of Perl for their public websites, and having successfully used Ruby on Rails for internal websites, the BBC have fused the two by creating a 'Perl on Rails' that has the advantages of rapid development that Rails brings, while performing well enough to be used for the Beeb's high-traffic public websites. This is already powering one of their websites, and is set to be used in the controversial iPlayer project as well."

Logfiles Made Interesting with glTail 131

Fudgie writes "My boss claimed it was pretty much impossible to create an entertaining way to visualize server traffic and events in a short time frame, so of course I had to prove him wrong. A weekend of neglecting my family produced a small ruby program which connects to your servers via SSH, grabs and parses data from Apaches access log and Ruby on Rails production log, and displays your traffic and statistics in real-time using a simple OpenGL interface (tested under Linux and Mac OS/X). It's a bit hard to explain over text, so please have a look at fudgie.org for an example movie, and more information."

Thinking about Rails? Think Again 482

wolfeon writes "In 2005, Derek Sivers of CD Baby wanted to scrap his site and perform a rewrite in Rails. He hired Jeremy Kemper, also known as bitsweat on Freenode, to help on the project. Two years later, through blood and sweat, the project was then canceled because of limitations of Rails. Rails just wasn't meant to do everything since it is very much "canned" project. Mr. Sivers has written an entry in the O'Reilly blog: 7 reasons I switched back to PHP."

Programming Erlang 314

gnalre writes "Every day it seems there is a new publication of a book on perl/python/ruby. Some languages however do not seem to get that sort of attention. One of those under-represented languages is Erlang, however for the first time in 10 years a new Erlang book has been published. As someone who had a brief flirtation with Erlang long ago, I was interested to see how the language had evolved in the intervening decade. I was also curious to re-evaluate Erlang to see what solutions it offered to the present day issues of writing reliable distributed applications." Read on for the rest of Tony's review.

Microsoft Opens Up Windows Live ID 212

randommsdev writes "Microsoft has announced the release of Windows Live ID Web Authentication. This means that WLID (formerly known as Passport) is now opened to third party websites to use as their authentication system. Any Windows Live user can potentially log in to a website that implements Web Authentication. Interestingly sample implementations are available in the Ruby, Python, Perl, and PHP open source languages amongst others — tested on openSUSE 10.2 but expected to work on any platform that supports these languages. More details are available in the SDK documentation."

Practical Ruby Gems 101

TimHunter writes "I was skeptical when I first saw the title of David Berube's new book, Practical Ruby Gems, from Apress. Do Ruby programmers really need a book devoted entirely to add-on libraries? Most Ruby programmers already know about the RubyGems package management system, and most already have their set of favorite gems. About a third of the way through the book I grudgingly admitted that Rubyists might be able to use this book. After all, even long-time Ruby programmers are unlikely to know about all the gems covered in this book. So then I had a new question. Would I find something in this book that made me say 'I didn't know you can do that with Ruby!'" Read on for the rest of Tim's review.

First R600 Review - The Radeon HD 2900XT 157

mrneutron2004 writes "Tweaktown seems to have the first review out of the gate on AMD's flagship R600 core. 'Our focus today is solely on the HD 2900 XT 512MB GDDR-3 graphics card – it is the first GPU with a fast 512-bit memory interface but what does this mean for performance? ... After taking a look at the GPU and the card from PowerColor as well as some new Ruby DX10 screenshots, we will move onto the benchmarks and compare the red hot flaming Radeon monster against Nvidia's GeForce 8800 GTX along with the former ATI GPU king, the Radeon X1950 XTX."

Beginning Ruby 172

TimHunter writes "Peter Cooper's Beginning Ruby: From Novice to Professional has two audiences, novices with no programming experience who want to learn Ruby as their first programming language, and veterans who want to add Ruby to their programming toolkit. Cooper's response to this challenge is a solid entry in the limited arena of Ruby tutorials. Even though the early chapters are marred by the occasional reference to an advanced topic, readers will appreciate the plentiful examples and thoughtful description of the Ruby language."

Is DVORAK Gaining Traction Among Coders? 559

coderpath asks: "At a recent Seattle Ruby Brigade hack night someone asked how many people used the DVORAK keyboard layout. Out of 9 people, 7 used DVORAK and only 2 were using QWERTY. I personally made the switch last Christmas, after 25 years of typing with QWERTY. What do you use? Have you switched to DVORAK? Have you been wanting to make the switch? Has anyone else noticed an increase in adoption of DVORAK lately?"

Facebook's Cross-Language Network Library 104

koreth writes "Facebook has released Thrift, a toolkit for making remote method calls. It generates interoperable network code in C++, Java, PHP, Python, and Ruby. Its protocol is much more lightweight (and probably much higher-performance) than SOAP or CORBA. Facebook uses it internally for high-traffic services like search. The license is extremely permissive."

GWT Java AJAX Programming 100

simon_kehler writes "The Google Web Toolkit (GWT) is a Java AJAX framework that provides an easy to use programming paradigm for web developers using the Java programming language. It is one of the more recent entrants into this field, but has been gaining a lot of traction and popularity. GWT Java AJAX Programming authored by Prabhakar Chaganti and published by Packt Publishing addresses the use of GWT to build ajaxified user interfaces. The author gently introduces the reader to GWT and then leads the reader through a series of tasks, each of which shows how to perform an useful action with GWT." Read below for Simon's review.

TextMate 226

OSXCPA writes "TextMate is a closed-source, GUI-based, extensible text editor that looks and behaves like a mashup of GNU Emacs ("Emacs") and NetBeans. This book is a primer and reference for TextMate. The blurb on the back of the book identifies the target audience as 'Programmers, web designers and anyone else who regularly needs to work with text files on Mac OSX.' After working with TextMate and reading through the book, the target audience is spot on. For example, the book briefly covers basic text editing, but provides in-depth information about basic operations (keyboard shortcuts, customizations, etc.) more advanced users will want to know and beginning users should know."

Why Is "Design by Contract" Not More Popular? 178

Coryoth writes "Design by Contract, writing pre- and post-conditions on functions, seemed like straightforward common sense to me. Such conditions, in the form of executable code, not only provide more exacting API documentation, but also provide a test harness. Having easy to write unit tests, that are automatically integrated into the inheritance hierarchy in OO languages, 'just made sense'. However, despite being available (to varying degrees of completeness) for many languages other than Eiffel, including Java, C++, Perl, Python, Ruby, Ada, and even Haskell and Ocaml, the concept has never gained significant traction, particularly in comparison to unit testing frameworks (which DbC complements nicely), and hype like 'Extreme Programming'. So why did Design by Contract fail to take off?"

MySQL Cookbook 64

Michael J. Ross writes "Of all the technical challenges faced by the typical experienced computer programmer, questions about syntax form a relatively small portion. This is especially true now that current coding editors and IDEs offer statement expansion and syntax checking. Rather, the most common type of technical challenge is understanding how to solve a specific data access or manipulation problem. Hence the growing popularity of programming "cookbooks," which are filled with "recipes," each comprising a concise statement of a focused problem, followed by a solution, with plenty of sample code to show how to implement it. For developers using the MySQL database system, the gold standard of such books is MySQL Cookbook, by Paul DuBois." Read below for the rest of Michael's review

Groovy in Action 154

Simon P. Chappell writes "I missed the partying in the 70's and so was not exposed to the full groovy experience that was available. You could say that I was a late developer (pun intended). Thankfully, I am now able to make up for lost time by learning the Groovy scripting language. For those of you not familiar with Groovy, it is a dynamic language designed to run on a Java Virtual Machine and be easy for Java programmers to work with; it looks very similar to Java and will freely inter-operate with Java objects and libraries. I've been tinkering with Groovy on and off for about two years now; learning Groovy in the old days, prior to this year, was a challenge with all of the design changes that were taking place. Groovy in Action (GinA) is the book that I'd wished was available back then. Dierk König, a committer for the Groovy project, has written this definitive guide to Groovy and after what has seemed an eternity to those of us on the Groovy mailing list, it is finally available."

Rails Cookbook 59

honestpuck writes "When reading the foreword of Rails Cookbook I felt a strong kinship with Zed Shaw, I too have fond memories of the first edition of Perl Cookbook and the way I relied on it once I'd taken the training wheels off. Since that one I have relied on several of the O'Reilly Cookbook series. It is only when I discard the early tutorial and dive in the deep end with a "cookbook" on my desk that I really start to learn proficiency." Read the rest of honestpuck's review.

Ruby Implementation Shootout 112

An anonymous reader writes "Ruby has an ever growing number of alternative implementations, and many of these attempt to improve the suboptimal performance of the current mainstream interpreter. Antonio Cangiano has an interesting article in which he benchmarks a few of the most popular Ruby implementations, including Yarv (the heart of Ruby 2.0), JRuby, Ruby.NET, Rubinius and Cardinal (Ruby on Parrot). Numerical evidence is provided rather than shear opinions. The tests show that Yarv is the fastest implementation and that it offers a promising future when it comes to the speed of the next Ruby version."
