Ruby performance improvement of 63% in 1.9.1

Ruby is very powerful object-oriented language. new Ruby performance improvement. Working with pure Ruby is really fun and interesting to me. I am the real fan of Ruby language.

Ruby performance improvement

I am working Ruby on Rails for around last four years. There is always I am thinking and all ROR developers are thinking about performance of application.

We always compare Ruby on Rails with PHP, Java, Python, dot net. We came to know that where we are lacking in ROR. Just one issue performance and memory issue.

When we got news about Ruby 1.9 is comming with performance improvement of 63%. Yes, It is not a joke. This is really great news for every ROR developers. Ruby 1.9 and Rails 3.0 is the future of internet.

Now I will talk about Ruby Software engineer who developed and worked on the Ruby 1.9.

Masahiro Kanai, who improved the performance of several methods in Ruby 1.9. He is the age of high school, just 17.

This year, Ruby 1.9 by the Fibonacci sequence of operations (multiple-precision addition) is,
Ruby 1.8 is slower than I realized Mr. Kanai is a challenge to freedom of choice camp Ruby faster.

In front of all the participants had a similar problem occurring, Ruby of type String, Array types (structures that may have an embedded data structure type object itself) and some of the faster method, attention collection. Oden’s is known to be well-covered tongue teachers. Ruby continued even after the camp’s efforts to speed up to approximately some methods to remove the macro in a constant loop of 63 percent to about 8 percent of success in speeding. This patch has been adopted by the community of developers Ruby, Ruby has been incorporated into the trunk (October 5, 2009).

many professional engineers and developers, with patience to hold out that the problem is resolved, probably as a programmer in one or two talents.

Ketai that builds skills and career tips for the professional engineer. Interviewers are already familiar with this series, the Mr. Ikuo Takeuchi, Professor Department of Creative Informatics, Graduate School of Information Science and Engineering, University of Tokyo. This time, who undertook the voluntary and discover if training for a talented programmer.

His mentor was Koichi Sasada (ko1). The performances of the methods he worked have been bumped up 63% in maximum, 8% in average. His patches were applied to Ruby trunk in Oct. 5 this year.

What he did for Ruby Performance tuning?

He took unnecessary macro references out from a loop. Masahiro spotted macros below in array.c, string.c, and struct.c were referred every time Ruby checked whether data was hold in a structure or not. Even though data were constants, Ruby saw the macros to judge data’s presence in every loop.

What I say now more… I am really happy and I can say this is the biggest news of 2010 in IT world.

One thing I want to mention here about Ruby on Rails. This thing is in mind of all ROR developers.

“Thank God, No need to look Jruby”

Ruby on Rails 3.0 released with new features

I am working on Ruby on Rails for past three and half year. It is really great to working with Ruby on Rails. Because working on Ruby on Rails is a really great feeling daily inventing new things, trying new things and contributing to ROR community. Discussing new things with ROR developers is really great.

On 5th Feb we got news about release of Rails 3.0 beta. We all developers are really waiting for that day. We checked the new version of Rails but what is more interesting.

The interesting part is what is new in Rails 3.0. So many developers contributed in Rails 3.0. They really worked and planned so hard.

Here I am making list what Rails 3.0 has, means new features:

Brand new router with an emphasis on RESTful declarations
New Action Mailer API modelled after Action Controller (now without the agonizing pain of sending multipart messages!)
New Active Record chainable query language built on top of relational algebra
Unobtrusive JavaScript helpers with drivers for Prototype, jQuery, and more coming (end of inline JS)
Explicit dependency management with Bundler

If you want to use the Rails 3.0 then you should install first following gems.

#gem install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n
#gem install rails --pre

Or you can use following command to install whole Rails 3.0 with dependencies

gem uninstall rubygems-update
gem update --system
#gem install rails3b

Important Note: Rails 3 requires Ruby 1.8.7+ , you should install latest Ruby version. You can download latest Ruby version from here.

Ruby 1.9.1

Here I am giving the list of gems and plugins which are compilable of Rails 3.0. you should check the following URL:

http://wiki.rubyonrails.org/rails/version3/plugins_and_gems

Now I am started working on Rails 3.0 and I am searching for the issues with Rails 3.0 because Rails 3.0 is in Beta so all ROR developer need to come up with issues of Rails 3.0 and try to fix that or submit that issue to community.

WordPress vs Joomla vs Drupal, Which is more popular and user friendly

Which CMS is most popular and most user-friendly in the world. WordPress vs Joomla vs Drupal all are best cms. you need to decide what type of site you want. This is most common question among the developers and clients.

So many times this question is questioned the answered But still I am going answer this question with my opinions.

WordPress vs Joomla vs Drupal

Biggest growth of jobs is WordPress. I am wordpress developer and I can feel this trend today.
We can this graph that displays the growth of wordpress. Seeing this graph We can say that in 2009 and 2010 wordpress is really rocking.

I worked on all the cms like wordpress, drupal, joomla and many more. But in this year I worked on wordpress for quite some extra time.

When we choose CMS we consider following points.

1. Which CMS will provide you Best Seo options

Ans: When we see and check the all CMS then I can easily say that wordpress has ability to provide you best seo option. After that I will must say Drupal is best option to go with. This will also provide you best seo option.

2. Which CMS is easy to make custom theme from custom design PSD

Ans: I can say with wordpress and drupal both creating a theme is very easy. any web developer who have very basic knowledge of PHP they can develop custom theme very easily.

3. Which CMS is easy for developer to make custom plugins, modules and components easily

Ans: If you started learning API’s of both the CMS. All are good and easy and all provided good amount of help on internet. But I can rate myself as follows:

a. WordPress

b. Drupal

c. Joomla

Anyways that is depending on your knowledge and understanding. All you need to spend some time to understand the API’s of all CMS.

4. Which CMS admin is most user-friendly and easy to use for non-technical people

Ans: For this point I must say wordpress is the best tool. Drupal has admin panel but little complex to understand and same with joomla.

5. Which CMS is most good for E-commerce site, Blog, Small site, News sites and company website.

Ans: I recommend again wordpress here. you can set up wordpress very easily and quickly with minium effort. For big websites like magazine and news sites wordpress is the great tool.

Next point is, for ecommerce and blogging wordpress is the great tool. If you are aware with wordpress then go with drupal.

Conclusion: If you want to develop very complex website with multiple features like ad management, forums, client support, video gallery, media gallery then go with Drupal.

So many very big websites are built-in Drupal and WordPress. Choosing the CMS is all depending on your client requirement.

how can we execute custom queries on wordpress

We can use the custom queries in wordpress. Using the custom queries we can fetch the wordpress table data as per our custom requirement.

how can we execute custom queries on wordpress

We you create your table then you can fetch values from that table using following command.

$ourdata = $wpdb->( "SELECT id, name FROM yourtable" );

If you want to create the table in wordpress then use following article.

https://purabtech.in/create-add-tables-wordpress-theme/

More example about executing the own custom quries.

$wpdb->query("
	DELETE FROM $wpdb->postmeta WHERE post_id = '123'
	AND meta_key = 'google'");

another example about adding the data into table which is from wordpress:

$table_name = "your_table";
 $welcome_name = "Mr. WordPressapi";
  $welcome_text = "Congratulations, you just completed the installation!";

  $insert = "INSERT INTO " . $table_name .
            " (time, name, text) " .
            "VALUES ('" . time() . "','" . $wpdb->escape($welcome_name) . "','" . $wpdb->escape($welcome_text) . "')";

  $results = $wpdb->query( $insert );

Getting the single value from any table

$user_count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM $wpdb->users;"));

Get the single row value from wordpress table

$mylink = $wpdb->get_row("SELECT * FROM $wpdb->links WHERE link_id = 10", ARRAY_A);

footer stickable to end of the browser window without fixed position

Many web developer always think about why footer is not sticking to end of browser. In this tutorial we will show you to footer stickable to end of browser.

This is scenario:
If content is less than footer need to go bottom of browser and if content is more than footer will go down as per content.

Many people think this is CSS developer’s But I am not think that way. because this is totally different problem.

Some people suggest to use header, middle container and footer height in percentage. But that is wont be possible for all the time.

Here I will give you the solution. Use following JavaScript in document.

<script type="text/javascript">
 var header_height = 150;
 var footer_height = 100;
var reduce_height = header_height+footer_height;
 browserHeight = 0;
 if( typeof( window.innerHeight ) == 'number' ) {
 //Non-IE
 browserHeight = window.innerHeight;
 } else if( document.documentElement &amp;&amp; (  document.documentElement.clientHeight ) ) {
 //IE 6+ in 'standards compliant mode'
 browserHeight = document.documentElement.clientHeight;
 } else if( document.body &amp;&amp; (  document.body.clientHeight ) ) {
 //IE 4 compatible
 browserHeight = document.body.clientHeight;
 }
 // window.alert( 'Height = ' + browserHeight );
 var min_height = browserHeight-reduce_height+ +"px"
 document.write('<style>#middle_container{min-height:'+ min_height +'}</style>');
 //document.getElementById("middle_container").style.minHeight = browserHeight-146+"px";
</script>

Here in this JavaScript I am assuming middle_container is your main block of content. You can change the variables as per your need.
