Just finished work on a Naive Bayes Classifier in Python. Was interested to benchmark Python performance with large data sets. Also had the chance to get to know more about Cython. Indeed as a C extension, it increased performance. So this project all started from my own implementation in PHP here. As it turns out, PHP is more performant than Python as of version 1.0.4 of this library. But there are differences. The Python module redis available at PyPi is not compiled as a C extension while the PHP counterpart is definitely a C extension. So the bottleneck here I suspect is with the Redis client. Expect some more enhancements to the Redis clients in future versions. ...

Today I was a speaker at Microsoft’s SQL on PHP event and I’m displaying the slides for the presentation below. It was a fun moment of sharing experiences, laughters and geekdom. Urbanesia - Open Source & MicrosoftView more presentations from Batista Harahap.

Jajan for Android is now Open Sourced at Github a few hours ago. I personally hope that by looking at the source code provided, more and more developers will sync to the tune of how easy it is to create an Android application. I wrote most of the codes 7 August 2011 in under 4 hours. Using ready made libraries already available within Android and also other third party libraries, it helped to ease the complications. ...

It’s 2012 now and Urbanesia is publishing a new OAUTHnesia client for Urbanesia’s API. This time it’s for PHP. Why it took so long to actually finish a PHP version is because we gave up on a third party library that is too complicated to do simple things. So without further ado, the codes are available below.

It’s been quite a day today. Did some code reworking with an app I showed you guys in my last posts. I decided to publish the Urbanesia class to Google Code and make it GPL v2. I encourage everyone to contribute and make more modifications. I’m not as experienced as others in Java, would love to learn more. The Google Code URL is: http://code.google.com/p/urbanesia-api-android/ Enjoy and empower yourselves developers!

On my last post, I mentioned the definition of Augmented Reality (AR). Now I’m adding the word Mobile to it. At the current time, platforms that I’ve tried to developed upon supporting AR are iPhone and Android. Well actually I coded once and used Titanium Developer to make the actual executable files for each platform. Titanium offers current web standards as a mean to create those mobile applications. I’m now using Titanium Developer 1.0 with the 1.1 Mobile SDK. The requirements to be able to run Titanium and produce for iPhone & Android are: ...

This year 2010 is set to be a cloudy year! Why? Well it’s practically the year where everything cloudy are launched. Web Development has never been so fun and so fresh before. The mobile world is getting its taste of how The Web will change its course. [caption id=“attachment_181” align=“aligncenter” width=“282” caption=“Web 3.0”][/caption] Over the years, your mobile phone anywhere in the world has been a primary need in metropolitans. When it’s came to this stage, mobile phones are practically a part of our daily routines. A new revolution is coming and it’s making mobile phones as its stage. ...
