ThreeJs - 3D data visualization on web


     I was into 3D since high school years. My first experience was making 3D models with 3Dsmax.
Since few years back Google Chrome had been trying to bring this technology to all desktops through web. With the rise of HTML5 it became possible to render 3D on client side by using WebGL via javascript. However, using WebGL via Javascript was not easy so open-source communities developed various wrapper libraries to simplify using webGL.
   Among them ThreeJS (http://threejs.org/) is one the best choice to use IMHO. It is more mature comparing to others, and there are many examples to follow.

It is better to see rather than reading, Check out this ThreeJS example: http://www.georgeandjonathan.com/#6
Is not it amazing?
Dynamic, interactive and open-source 3D visualization directly on your Chrome Browser.
It runs on the latest Android Tablets and Phones too.
In few years, I think everyone will be able to browse 3D sites on their devices.

So, by using this library I am trying to make some impressing data visualization.
Here is how I visualized the Word Cloud in 3D:


  Unfortunately, it is just a screenshot from my browser and next time I am going to upload live demo.

NLP for Uzbek language

    Natural language processing is an essential tool for text mining in data analysis field. In this post, I want to share my approach in developing stemmer for Uzbek language.      Uzbek language is spoken by 27 million people  around the world and there are a lot of textual materials in internet in uzbek language and it is growing. As I was doing my weekend project " FlipUz " (which is news aggregator for Uzbek news sites) I stumbled on a problem of automatic tagging news into different categories. As this requires a good NLP library, I was not able to find one for Uzbek language. That is how I got a motive to develop a stemmer for Uzbek language.       In short,  Stemming  is an algorithm to remove meaningless suffixes at the end, thus showing the core part of the word. For example: rabbits -> rabbit. As Uzbek language is similar to Turkish, I was curious if there is stemmer for Turkish. And I found this: Turkish St...

Three essential things to do while building Hadoop environment

Last year I setup Hadoop environment by using Cloudera manager. (Basically I followed this video tutorial :  http://www.youtube.com/watch?v=CobVqNMiqww ) I used CDH4(cloudera hadoop)  that included HDFS, MapReduce, Hive, ZooKeeper HBase, Flume and other essential components. It also included YARN (MapReduce 2) but it was not stable so I used MapReduce instead. I installed CDH4 on 10 centos nodes, and I set the Flume to collect twitter data, and by using "crontab" I scheduled the indexing the twitter data in Hive. Anyways, I want to share some of my experiences  and challenges that I faced. First, let me give some problem solutions that everyone must had faced while using Hadoop. 1. vm.swappiness warning on hadoop nodes It is easy to get rid of this warning by just simply running this shell command on nodes: >sysctl -w vm.swappiness=0 More details are written on cloudera's site 2. Make sure to synchronize time on all nodes (otherwise it will give error on n...

NAT Traversal or how to make P2P on Android

Many of us used BitTorrent(or uTorrent) to download files on internet in a short time. Their download speed is high due to Peer-to-peer technology. That means, rather than downloading file from server, we are getting the file from another computer. But how two computers that have a local IP and are behind NAT, how they can connect each other? For that, NAT Traversal methodologies come for help. Note that there are mainly 2 types of NAT: Symmetrical(complex NATs:carrier-grade NAT) and Full (home network or small enterprises). let us consider Full NATs first. Methodologies of NAT traversal are: UPnP - old and hardware oriented method NAT-PMP (later succeeded by PCP)- introduced by Apple, also hardware oriented(i.e: not all routers have it, and even if it had, it is turned off by default) UDP Punching  - this is done by STUN which uses public server to discover NAT public IP & port TCP Punching -  similar to UDP punching but more complicated Symmetrical NATs are...
