Kamaelia: Open Source Python Framework

June 28, 2008 § Leave a comment

Kamaelia is not yet another Rails-esque framework, thus making it more interesting.

Kamaelia is open source framework for building concurrent system. It was conceived inside BBC.co.uk r & D lab. It is written in Python, making it double interesting.

It draws its inspiration from UNIX pipeline. UNIX pipe allows chaining processes so that the output of current process goes directly to the input of the next process. The ‘pipeline’ module is called Axon.

From its documentation, Kamaelia is more like collection of components. The components comprises a lot of thing; TCP server/client, GUI builder, Audio codec, IRC client, etc…

This framework is most definitely different.

Fuck It Principle

June 11, 2008 § Leave a comment

In software development, being able to say fuck it, and not implementing the not-so-important features is a good thing.

By saying Fuck It(TM):

  • There’s less code to debug.
  • There’s less features to unit test and functional test.
  • Security schema protects less things.
  • There’s less complication (in an already complex application). See: Feature Creep
  • Deadline does not get pushed further and further.
  • It prevents a decently good idea becoming stupid, by having too much features.

As a reminder, I must never ever attempt to add too much Cruft.

Fuck It is more or less similar to YAGNI, as 1 reader pointed out.

Hope this post can be a helpful reminder for readers as well.

Zend Framework… Performance & Caching (part 2.1)

July 30, 2007 § 2 Comments

In my previous post (here), I promised you about performance of Zend Framework.

Unfortunately, I cannot give you the result yet. Because it is still work in progress.

So here is the low-down:

First of all, I’m researching (learning) about Zend_Cache, which consist front_end and back_end. Don’t worry about the mumbo jumbo just yet. The front_end is nothing more than helper functions that can help you optimized specific parts of your application code. The back_end utilize different types of medium Zend Framework use (as of version 1.0, there are 5 different choices of storage: filesystem, APC, SQLite, memcache, or ZendPlatform). ZendPlatform is not free.

The plan is to implement caching and run stress/load testing on both before and after-cache. Then I can publish the result here.

Currently, the front_end confuses me on how to utilize it… It promotes sloppy code. Or is it me not finding the good tutorial online?

Here is an example from Zend_Cache_Frontend_Output (<– it’s 1 of 4 front_end Cache objects):

(assuming $cache object has been initialized using the factory pattern)

if(!$cache->start(‘tag_for_block_of_PHP_code_below’))

{

[you block of PHP code]

$cache->end();

}

How in the world does this promote elegance? I supposed it should be fine if I enforce its usage strictly on View pages. But still…

Another thought would be to cache all public functions inside model classes using Zend_Cache_Frontend_Function. It’s the cleanest, most seperated (because hidden inside model classes), & has the highest impact (because of caching database calls made by the functions).

(Brain starts steaming up…)

So now y’all know why I’m so late in giving the performance report. Stay tuned for more tips on how make your Zend application… “enterprise-level”

Zend_View…

July 24, 2007 § 3 Comments

Seems kind of weak to me.

Disclaimer: I’ve been developing a web application using Zend Framework for quite a while now (couple of months).

Couple of points why it is weak:

Using Zend_View is quite a labor. I have to setScriptPath() manually for various .phtml that’s located not in the standard location. Of course readers might wonder, why would I want to place .phtml files in NON-default places? Please see the next point below.

In RoR and CakePHP, inserting a block of view inside another view page is a breeze. Zend_View doesn’t have render_partial() or anything remotely close to that. In order to make my extended View object have renderPartial(…), I need to call setScriptPath() to include the inner view element.

Another “I cannot believe they didn’t have it” moment, Zend_View has no capability of setting global layout. Again, I have to implement such function in my extended View object.

Granted, extending Zend_View object is pretty simple job. Thus, it is not something to get mad about. But it would be nice to have out-of-th-box experience like Ruby on Rails.

Overall, Zend_View is definitely lagging behind its competitors.

OpenAds…

June 14, 2007 § 2 Comments

is an open source Ads Management System.

It’s 7 years old project, now backed by a commercial entity.

System Requirements:

  • PHP 4
  • MySQL or PosgreSQL
  • I think Apache 1.3 would suffice

This company and its open source predecessor would certainly spice up the world of advertisement online, which is already hot because of GOOG vs MSFT (DoubleClick) fiasco.

Me? I’m just glad that I now know an alternative solution to ad-based revenue.

Zend Framework… (Part 1)

June 5, 2007 § 1 Comment

Is intriguing and disappointing (a bit) at the same time.

Disclaimer:

This is just part 1 of what’s going to be an ongoing reviews. I decided to do the review this way because I realize that 1-2 days is definitely not going to do the framework justice. The review would take weeks at the very least.

So, let’s talk about why it is intriguing:

It’s web development framework from the official PHP folks. Of course it’s gonna be great. There are lots of PHP developers who are excited with this very thought, me included. Granted I’m late in the party.

Zend framework finally reached version 1.0, it seems to be ready for prime time? Let’s give it a shot.

Reading at the manual and the source code a bit, everything is a component in Zend Framework. Awesome! It seems to have everything I need and more. Once I understand how the component gets called, I’m sure I can develop a component that’s also plug n play in CakePHP. One component to rule the web!

Lastly, My my my… The directory structure is very familiar. Reminds me of RoR and CakePHP… especially CakePHP.

Now let’s talk about what makes me iffy at first:

I swim in RoR, CakePHP style framework for quite some times now. Somehow, I’m starting to like to be hand-held. I know, i know, that sounds bad. Software developer must make their own tools! With their own conventions! and their own configurations! I’m a bad developer for wanting the tools to spoil me.

Ok, enough with the guilt trip. Zend Framework doesn’t force me anything. It seems that I would have to write my own index.php, initialize the Zend_Db or Zend_Cache myself. Not a big deal, I’ll just have to get used to the new mind set.

But that doesn’t mean Zend doesn’t have any conventions. From some tutorials I saw IndexAction function name inside Zend_Controller. That’s an interesting naming convention. Reminds me of Struts Action in JAVA world (Shivers…….).

But what would be the real kicker is:

How performant is it? I haven’t been able to find some data that shows the performance capacity of Zend Framework. If readers have some data, or personal experience with it, please share those to me :)

I have yet to see what it can deliver better than CakePHP. But! (This is a big But) This is just the first review. I have yet to complete an application with it.

Stay tuned. Second review will come after I created a blog engine with it and stress test it. That being said the second review would be about performance.

References on how to install Ruby on Rails on Mac OS X

May 17, 2007 § Leave a comment

  1. http://hivelogic.com/narrative/articles/ruby_rails_lighttpd_mysql_tiger
  2. http://developer.apple.com/tools/rubyonrails.html
  3. http://locomotive.raaum.org/

Number 3 is interesting because it provide project containers to all of your Ruby on Rails application, but the 75 MB download is a bit too much though.

I cannot really add more insight to the installation process because RoR seems to be born inside Mac OS X. Installation is dead simple, documentations are plenty as well.

Checklist when using Python for Web Development

May 16, 2007 § Leave a comment

  1. Download latest stable of Python (as of today version 2.5).
  2. Visit cheesecake for some module shopping.
  3. Before installing anything else, easy_install module is a must-have!
  4. If you are planning to use MySQL database, install module mysql-python.
  5. On top of MySQL,if you need ORM (Object Relational Mapper), download SqlAlchemy.
  6. If you are planning to do unit testing, install nose.
  7. If you need MVC Web framework you can either:
  8. If you are thinking of rolling your own architecture:
    • For getting up to speed in Web Server development, download CherryPy.
    • As you get large number of hits, you might be considering Lighttpd. To communicate CherryPy & Lighttpd, install scgi via: easy_install scgi.
    • If you need templating language for generating dynamic html, there are gazillion of them, I don’t know which one is good: Cheetah(PHP-alike), Kid(XML-ish), Genshi (XML + embedded Python), Mako (not XML), etc.
