1. Be up to date
Try to be a part of the online communities that discuss Ruby and Rails programming so you can be updated on the latest developments in resources, updates, fixes, reviews that you can find online. This robust and constantly moving community is one of the best features of open source technology like Ruby and Rails, so use it and learn new things from it.

2. Utilize plug-ins.
Scratching you head and looking for the right code? Fear not. sites like the Rails Plug-in Directory and Core Rails feature plug-ins that do all the work for you. Many other like-minded sites exist online, it up to you to find them. Such power at your fingertips is one of the many benefits of using open source technology like Ruby and Rails.

Learning Ruby

As with any other computer language, writing codes, mostly using IRB, is the best way to learn Ruby. If you have written a number of lines, place it in a file and run it. After you’ve figured out how it works, learn about the unit testing framework, try to discover the machinery that makes it work. Another way is to get involve in discussions and if you come across unanswered questions, do research, deliberate and come up with an answer. It would also be helpful if you let the program reveal itself to you, accept it as a simple program and could give you a straightforward solution to a problem.

Ruby as a Programming Language

The Ruby language has been used for scripting jobs, but most often it is used as a general-purpose programming language. It can be used to write GUI applications and middle-tier server processes, as well as for managing server machines and databases. Ruby is also used for working with Web pages, interfacing to databases and producing dynamic content. Some clients are using it to write artificial intelligence and machine learning programs, and have been found to be useful as a means for exploratory mathematics and formatting book publications. It is a wonderful language for creating solutions in a variety of problem domains.

Ruby as ApplyScript Replacement?

With the recent developments going on between OS X and Ruby, A lot of Ruby addicts are convinced that Ruby has the potential to be the de-facto OS scripting language of choice within the next few years. A lot of programmers find AppleScript secretive or hideous enough to avoid it wherever possible. There’s an article recently that compares an AppleScript code and it’s ruby alternative:

The AppleScript Code:

tell application “TextEdit”
get paragraph 1 of document “Read Me”
end tell

The Ruby Alternative
app(’TextEdit‘).documents[’Read Me‘].paragraphs[1].get

In reality, AppleScript is much more easier to understand, but the Ruby version is easier to remember in terms of its construction and as long as you’re familiar with Ruby syntax, you won’t get lost.

Bottom’s Up

That is a development style that begins with the overall layout and ends with the details or nuances on how the web page works. It is best for visually intensive sites that need a lot of graphics but equally important is the way that visual layout translates to a well developed page. Keeping your pages clean and neat(without sacrificing layout/graphics) can be achieved with some nifty tools that come from many sources on the web. Developer forums allows people like you and me to get real world solutions and even snippets of codes to help us do the most common tasks. Common sense is the basis of such a well developed page for the headaches will surely come if you fail to properly do your page…

Form-Based Web Authentication

Bart — Thu, 16 Jun 2011 14:09:47 +0000

One of the most common forms of web page security that aims to keep legit users in and intruders out for no good out. They can come in many forms and types such as the “Remember Me” check box that eliminates repetitive data entry for login information which most web pages use. Secret questions and password strength checks is another way of delivering proper security to the page’s standards.
One issue that is being extremely developed is to prevent denial of service attacks through rapid fire login’s that aim’s to break the security of a page and last is to use third party web authentication security that lets other people handle the dirty work of screening out legit from.

Plug-ins and Rails

Bart — Wed, 30 Mar 2011 20:49:48 +0000

Using plug-ins with Ruby on Rails is really not hard. In fact, it is quite easy to use plug-ins because it already has a very well developed plug-in. This means that plug-ins can be easily installed and used in the application. It is not unusual for a developer to use up to six plug-ins for every single Rails application.
Plug-ins are quite helpful because during the process of development, the plug-ins already have the code that you need ready. You won’t even have to write it yourself. This is one reason why developing on Rails is so fast and easy.

Cross-Platform/Browser Compatibility

This means designing your page well enough to not only display but work properly over the several browsers that are out on the web. Many developers fail to consider the subtle differences that web browsers have when it comes to page function. Firefox being the most widely used browser is mostly covered but IE with Microsoft’s branded technology tends to require a bit more to get the ball rolling.
Browsers such as IE7, IE8, Opera, Safari, Firefox, Chrome and some others are the most commonly used browsers so taking time to install copies and review code will go a long way to help your page function flawlessly across borders.

The Garbage Collector

The Garbage Collection feature has been introduced in Ruby recently. Though this useful feature is already available in other programming languages, Ruby made an effort to make it more efficient. Garbage pertains to the memory that has been allocated but not freed even if it is not needed anymore. An automatic mechanism for finding and clearing out the garbage is available in Ruby. It also frees memory in just a snap. The good outcome of this is the reduction of memory leaks. It cleans up the storage space in the memory effectively and avoids a lot of application boo-boos. The garbage collector is automatically tasked of freeing unused objects which makes it a more effective programming language.

Productivity and Rails (1)

editor — Wed, 10 Nov 2010 06:22:43 +0000

Rails can help you achieve a new level of productivity by combining the right elements in the right amounts. A number of the most important ingredients that make up Rails:

• Ruby – use the Ruby programming language and it’s unique design makes it easy to create domain-specific languages and to do metaprogramming. Rails takes full advantage of this.

• Full-stack MVC framework – a framework where Rails provides all the layers and they work together without an effort.

• Convention over configuration – Rails application uses few simple programming conventions that let it figure out everything by way of reflection and discovery.
