News Fishing – Stumblish Way of Browsing the Latest
October 11th, 2009Since I introduced myself to Google AppEngine, I’ve always liked it. It’s truly a joy to develop on the AppEngine platform. Due to hectic work schedule, I wasn’t able to get my head around to thinking of a new toy project so I could get into AppEngine again. Well, this weekend I decided to take a break from work-work and build something on the side for a change.
When I was working on the NewsXperiment project, I was neck deep in the RSS/Atom feed world. All the news feed sources that I had accumulated for NewsXperiment was hanging around to be used for another purpose. So came “News Fishing“.
I needed a way to quickly peek at what’s happening “right now” without being lost in a jungle of “stuff” on a web page or in an RSS reader app. I wanted to see “one” news item at a time, and if my interest in intrigued I wanted to dig in more by clicking on the link to the original page. If not, keep fishing. That was my initial and only requirement and it turned out to be the premise of “News Fishing“.
On the techie – geeky side of things, News Fishing uses quite large set of features that are provided by the Google AppEngine platform; Crons Jobs, Task Queues, Memcache etc. I opted on using YUI 3.0 as the javascript library of choice on the frontend.
- As I’m typing this, two mobile apps (for iPhone and Android phones) for News Fishing are in the works.
Must Call This Function!
June 30th, 2009I was going through some code refactoring today, and needed a certain set of classes calling a particular function during their initialization.
I needed the function to be absolutely (i mean absolutely) implemented by any deriving classes of the base object.
I needed the function called automatically, so I won’t have to remember calling it anytime I derive something new out of the base class.
So, here is how I accomplished this lovely must-call-this-function pattern.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | interface ISample { public function makeSureThatThisFunctionIsCalled(); } abstract class ASample extends TheParentClass implements ISample { public function __construct ($someParams) { parent::__construct($someParams); $this->makeSureThatThisFunctionIsCalled(); } } class Sample extends ASample { public function __construct($someParams) { parent::__construct($someParams); } public function makeSureThatThisFunctionIsCalled() { // do whatever you need to do here.... } } class AnotherSample extends ASample { public function __construct($someParams) { parent::__construct($someParams); } public function makeSureThatThisFunctionIsCalled() { // do whatever else you need to do here.... } } |
The code should be self explanatory for the OOP savvy folks. Here is a very short description of what happens here.
Our actual class “Sample” extends the abstract class “ASample” which in turn implements the interface “ISample” (don’t worry about extending the TheParentClass). Implementing the “ISample” will require us to actually implement the makeSureThatThisFunctionIsCalled() function somewhere either in “ASample” or “Sample” class. We need class specific implementation of the function, so “Sample” and “AnotherSample” classes implement it.
Oh great, yay! We enforced our derived classes implement a function of the interface. Big deal!
How will we make sure that “makeSureThatThisFunctionIsCalled()” function will actually get called ?
In this sample, all the deriving class constructors call their parent::_construct which keeps bubbling up to TheParentClass so on and so forth…
So, we simply stick in “makeSureThatThisFunctionIsCalled()” in the immediate parent’s constructor and tada !!!
Our must-be-called function is surely getting called during the object’s initialization.
This may sound like a glorified initializer, but you never know. You may just need something like this.
Suicidal Pattern and Observers
June 17th, 2009The other day, I came up with a sort of bizarre idea of exception handling in PHP. Not so interestingly it may be, you’ll find out as you read, this design pattern is called “Suicidal Pattern“.
The idea is around an object throwing itself as “throw self” (actually throw this) and it’s own handler catching and handling and announcing to its observers.
And here it goes:
MiaCMS 4.9 Beta Released
June 17th, 2009MiaCMS released a beta version of the next minor release of the project, version 4.9. The changes for this release are as follows:
General Changes:
- PHP 5 is now required (PHP 4 users must stay on the 4.8 branch until they can upgrade to PHP 5)
- Accessibility cleanup added
- PHPMailer upgraded
- Updated the MOStlyCE editor to latest TinyMCE core
- MOStlyCE support added for skins and content templates
- Added a new content bookmark component/module
- Added a new tag cloud module
JavaScript Related Changes:
- Fixed minor JavaScript issues identified with the 4.8 configuration
- Increased performance
- JavaScript now loads either in the document <head> or just before the closing </body> tag instead of scattered throughout the page; most of the time it will load just before the closing tag, since there are additional performance benefits to that method (http://developer.yahoo.com/performance/rules.html#js_bottom).
- Upgraded the Yahoo User Interface (YUI) from 2.6.0 to 2.7.0
Since the JavaScript architecture was fully rewritten with the 4.8 branch and again refined with 4.9, we’ve created a new starter doc on the wiki that details more about working with JavaScript (and YUI) within MiaCMS – http://docs.miacms.org/wikka.php?wakka=JavaScriptForDevelopers.

Update
June 12th, 2009It’s been a while that I’ve put anything in here. Busy times !
Big news of the previous months… I brought an end to the good old times at S1 Corp after 8 years, and I moved up to the Bay Area (a.k.a. San Francisco), and started working for eMeter Corporation with some brilliant minds in the software industry. I am thrilled. Moving was a %#$^ though. Still have lots of stuff left at Los Angeles to be picked up, sold, given away in the near future.
When I was dropping the moving truck back at the U-Haul, I was told “Welcome to the better half of California!”. Time shall tell.

A computer once beat me at chess, but it was no match for me at kick boxing.

Computers make it easier to do a lot of things, but most of the things they make it easier to do don’t need to be done.
Andy Rooney
The good news about computers is that they do what you tell them to do. The bad news is that they do what you tell them to do.
Ted Nelson
The real danger is not that computers will begin to think like men, but that men will begin to think like computers.

Why is it drug addicts and computer afficionados are both called users?
