Ruby on Rails Developer expertise for Business on Web

Fremont based global technology Services Company DCKAP announced today a proactive development initiative in Ruby on Rails technology for business, keeping pace with surging market growth.

 

Ruby on Rails, developed by David Heinemeier Hansson in 2003, is an Open-Source web framework built using Ruby. The main goal was to enable developers to rapidly develop web applications backed by SQL databases. Nearly 8 years later, Ruby on Rails has built itself a niche in the IT development world.

 

January 20, 2012, Rails 3.2 was released. The major improvements were the speed of resolving routes was improved. For the ease of development, Rails 3.2.3 had allowed any field to be set in a mass assignment action in a database record and then left it to the developer to lock down the application. Ruby on Rails introductions are intuitive and enable the creation of applications that demand user attention and can be easily integrated into Web applications to make them highly interactive. With creativity and professionalism of the Ruby on Rails developer, businesses will derive maximum return on investment. Ruby on Rails developers, use Ruby on Rails as a versatile tool to create highly interactive Web applications.

Rails 3.2.3 has been released!

This release changes the default value of config.active_record.whitelist_attributes to true. This change only affects newly generated applications so it should not cause any backwards compatibility issues for users who are upgrading but it may affect some tutorials and introductory material. For more information see the mass assignment section of the ruby on rails security guide

Rails 3.2.3 also introduces a new option that allows you to control the behavior of remote forms when it comes to authenticity_token generation. If you want to fragment cache your forms, authenticity token will also get cached, which isn't acceptable. However, if you only use such forms with ajax, you can disable token generation, because it will be fetched from meta tag. Starting with 3.2.3, you have an option to stop generating authenticity_token in remote forms (ie. :remote => true is passed as an option), by setting config.action_view.embed_authenticity_token_in_remote_forms = false. Please note that this will break sending those forms with javascript disabled. If you choose to not generate the token in remote forms by default, you can still explicitly pass :authenticity_token => true when generating the form to bypass this setting. The option defaults to true, which means that existing apps are NOT affected.

We've also adjusted the dependencies on rack-cache and mail to address the recent security vulnerabilities with those libraries. If you are running a vulnerable version of mail or rack-cache you should update both gems to a safe version. There were also some regressions in the render method that were fixed in this version.

GridGain Claims It’s Big Data 2.0

GridGain Systems has upgraded its namesake Java-based open source middleware platform for real-time Big Data processing.

Unlike complex, decade-old SQL, ERP or Hadoop ETL systems that use dead data for batch offline processing, the new GridGain 4.0 will process live data so businesses can get meaningful results faster from low-latency real-time transactional and analytical processing.

By comparison GridGain CEO Nikita Ivanov claims Hadoop is only good for long-term historical storage. GridGain is more like "Big Data 2.0."

Rails Tutorial sample screencast vide

I'm gearing up for production on the second edition of the Rails Tutorial screencasts, and I've posted a sample video showing the setup I'm planning to use. I'm going to start screencasting within a few days, so now's your chance to give me feedback (at admin@railstutorial.org) before the screencast train leaves the station.

Here's the sample video:
Rails Tutorial 2nd edition sample video

Update: I've also included a second video at a slightly different resolution.
These are some of the items I'd like to get feedback on:

• Video. Is the video crisp? Are the size and format OK?
• Sound. Is the sound clear? Is the volume good?
• Screen resolution. The video's resolution is 1344x756, which uses the standard HD aspect ratio of 16:9 while still fitting on the screen of my MacBook Air. Let me know if it doesn't look good on your system. (If this resolution doesn't work, I might have to buy a new computer, which I'd really rather avoid…)
• Applications and workflow. I'm planning to use iTerm and Sublime Text as the principal development tools. I'm 95% likely to stick with those, but let me know if you violently disagree with either choice. Note: The main reason for switching to Sublime Text from TextMate (the editor used in the first edition) is that it's comparably good while also being cross-platform.
• The video includes some other details, so please watch it all the way through if you're planning to comment. (It's about 11 minutes long.)

Any other observations or suggestions are greatly appreciated (admin@railstutorial.org), especially if they arrive within the next couple of days. Thanks!

The Ruby on Rails Tutorial, now with Twitter's Bootstrap

Due to popular demand, I have prepared a new version of the Ruby on Rails Tutorial using Twitter's Bootstrap framework. The result, which represents the final draft of the 2nd edition, can be found here:
http://railstutorial.org/book?version=3.2

This is a substantial revision, involving significant code changes, new mockups, and new screenshots. As usual, bug and typo reports are welcome (admin@railstutorial.org). Once it looks like the kinks have been worked out, I'll release a full PDF of the 2nd edition.

I'd like to thank reader Colm Tuite for his excellent work in helping to convert the book's sample app to Bootstrap. I'd also like to thank Thomas McDonald for his outstanding work on the bootstrap-sass gem.

Since some readers might find themselves stuck in the middle of the pre-Bootstrap version, I have included a copy here: http://railstutorial.org/book?version=3.1

Otherwise, I suggest using the latest version: http://railstutorial.org/book?version=3.2

Thanks to all those who encouraged me to make this change. It was a lot of work, but based on reader feedback I'm confident that it's the right move. Bootstrap is an excellent CSS and UI framework, and I'm excited to have it be part of the Rails Tutorial.
