Howdy,
When I was in my college, I tried to implement Web Map Service (WMS) and Web Feature Service (WFS) as a foundation for a distributed Geographical Information Systems (or better known as GIS). My academic advisor at that time told me that this idea is not entirely new, but there are still a lot of people didn’t know about it yet. So with this topic as my thesis, he wished that one day people will know about this technology.
The implementation that I made was quite simple actually. But let me tell you the complete story. At first, I was thinking about develop a geographical operation that can be operated via web service in the clouds. After some weeks of analyzing and gathering informations, I found out that this work could be really hard and time consuming. I didn’t have background in geography–I’m a computer science student–and I didn’t have much time before the next graduation. Finally, I just created a spatial data repository and make it accessible across the network using GeoServer,an Open Source implementation of WMS and WFS. I, then, created a simple web application to pull the spatial data and display it to the browser. I also provided a simple data update feature, utilizing one of the feature of WFS. I used OpenLayers to create the application. It’s really simple actually.
In my graduate study, right now, I want to try something entirely different. I want to explore MapReduce, a programming model for processing a large scale of data in a distributed environment. I heard about this model from some mailing lists and websites, surprised that the paper [pdf], the lecture notes and videos are easy to get. So, for the time being, I decided to do some experiments in order to learn something about it.
It’s still a plan in my head actually. I never talked about it to my thesis advisor (because I have none yet). But I can predict some problems that I will be dealing with if I do this research plan. They are:
- The case. I don’t have any idea about the case that I should solve with this research. My college’s advisor told me about doing something in bioinformatics like genome assembling. I think I will cosider it. But I’m open for an idea.
- The machine and its network. The lab are always busy with the other graduate student. Fortunately, one friend of mine told me that there is another place that I can use in the campus to do experiments. But I should create a permission letter first. Okay, I’ll do it.
In the mean time, I’ll focus myself to learn about MapReduce. Maybe I’ll post something about it in this blog. If you have a suggestion about what should I do with this programming model, let me know. I’d be really glad to hear it.

Howdy,
It has been a long time since my last post in this blog. I just wrote some posts in my old blog when suddenly it’s already 2010. Wow, time really waits for no one. So in this post I wanna sum up what has been happening in the last year. Well, I don’t actually do anything big actually, but I made some progress in live, I guess.
Here I come. I spent my first months in 2009 in my homeland. I was recovering from my illness and successfully gained some weights. I did some theme for this blog, exploring with domain and paid-hosting, maintaining my virtual social live in Facebook and Twitter. Anything that can be done in the house, I’ve done it. Oh yeah, I also created a simple blog aggregator or usually called planet to lists all of my class’s blog posting. Continue reading
Howdy..
Okay, I just got this first assignment. Me (and all the other students) must submit a paper about some topics provided by the teacher. Because this is my first time, I just do what I can. I wrote it like I used to write in blog. By the end of the day, I finally finished about seven pages of them. I printed it out, booked it, and submitted it to the academic. Then, I sent the pdf version to the teacher by email.
On the next day, I met my classmate. He asked me about the paper. I told him that I have sent the pdf version of the paper to the teacher email and have submitted the “real” paper at the academic. He told me that he’s using chm format for the paper. Continue reading
Dear blog,
Today is the last week before the mid term exam. Life is fast, right? I still remember when I got attached by this WSD, and now it’s already a year after that. Six months after that, I finally be able to recover. And got into this graduate study.
It’s a new city, you know? This city is totally different with the one from the old days. I can still found cultural politeness such as say hi and smile to older people. The great thing is, they all do it sincerely. The city itself is exotic. There were so many tourist attractions here, make me feel no boring. Continue reading
The coolest moment here means the very moment you felt you are the coolest person on earth. Do you ever experience it? Because this is my blog, so I guess I’ll take the first turn to tell you about my coolest moment, at least up until now. I know that it could be a little narcissistic, but I hope you don’t mind. Okay, fasten your seat belt, here we go..
It happened in the third year of my college. We were having parallel programming course. In the middle of the course, our teacher gave us some cases that we had to solve using parallel principles. The class was divided into some groups with their own cases to solve. Every group must presents the solution twice. The first presentation tells the parallel principle used to solve the case. While in the second, the group must shows the implementation of the solution they presented earlier. There were some weeks range between the first and the second presentation. Continue reading
