Gerakan Bawah Tanah - Mr. GBT

I just thought that I should add books that I have recently read to shelfari.com . I have an account there but have not logged in for quite a while. Now, I am stuck and don't know what to do. It seems that I cannot add a book directly by typing the author and the title of the book. I can do a search, but the book that I was trying to add (Perahu Kertas by Dewi Lestari) was not found. So there's no way to add the book to my virtual bookshelf. Oh well. Let me try another virtual bookshelf like goodreads.com.

Just what do you think our world would become? Here's a picture taken from a trash bin near my office (on campus). Oh... all those plastic. :((

Last night was my first gig this year. It was tiring … We had to play for more than a dozen songs. My shoulder is still in pain this morning. But, it was fun. Let’s see how many gigs will I have this year … Hopefully a lot ...

Greetings from Bandung, from ITB to be exact. This week is the first week of school. This term I am teaching two classes. Originally, I was listed in two other classes. I asked other lecturers to take over those classes. Now, I have two classes only. Well, I was surprised to see the number of students taking my class; 83 (and perhaps more). Oh boy... The class was design to accomodate 40-ish students. I have to find an assistant to help me marking students' assignments. My other class, which is a grad level, is smaller. I think there are 40-ish students. I can handle that. Unfortunately, I have to change the schedule for this class because it was exactly the same time slot as my other class. So wish me luck this semester ...

School year has started yesterday. Everybody is on campus. Information (importan and not-so-important) is starting to flow. The gate has been opened. It's time to catch up with this and that. I have to delete lots of stuff (emails) these days. Oh well ...

I was told that in terms of number of Facebook users, Indonesia is number 3 in the world - after USA and UK. [reference / url needed] Whoa! This is something that you cannot predict. I can assure you that this is true. In Indonesia, everybody (and his/her pets) perhaps has facebook account. Some even have more than one accounts. (One for each personality? ha ha ha.) The number of Facebook users in Indonesia exceeds the number of people in Singapore and Malaysia! Take that! Because of Facebook, many people buy BlackBerry (BB). Yes, you may want to check with RIM that the number of BlackBerry users in Indonesia is unbelievably large. I guess, we can safely say that facebook is a killer application for BlackBerry. At least, that is true in Indonesia. My point is that Indonesia is an important market for BlackBerry and Facebook. This is also true for Nokia. (Indonesia is perhaps the biggest market for Nokia smartphone, such as communicator!) Why Facebook and BlackBerry are popular in Indo

Good morning ... blue sky ... bright heart Greetings from Bandung, Indonesia ...

It is interesting (and ... believe it or not, nice) that this blog has become irrelevant. Meaning, nobody visited this blog intentionally. :) A few years ago, this blog was in the top 10 of Indonesian blogs! I understand completely if you don't believe it, but it is true. I am not making this one up. I guess, a few years ago there were not many blogs. Today, there are too many good blogs to visit (and read). So, this blog is nothing ... At the same time I am more focused on my other blog . A deadly combination for this blog :) [Ok, I am planning to write more on this blog.] The good thing about this is that I can post anything I like and nobody will notice it :)

Two days ago, Hafiz gave me this paper: The Uneasy Relationship Between Mathematics and Cryptography Export by: Neal Koblitz Notices of the AMS, Vol. 54, No. 8. (September 2007), pp. 973-979. Done reading it. Wow. It's a great article explaining what happened behind the hood. Need more articles like this. Anybody?

no, this is not a song list. I’ve just got my coffee … the thing is, i shouldn’t drink too much coffee. there’s going to be two meetings today. so, i have to choose which meeting i will have coffee and which one i will be in a unknown-(unstable?)-state. and … i already have had my coffee (right now). i don’t want to think about the meetings. whatever will be, will be let me enjoy my coffee …

Ideas. ... floating around ... ready to be captured ... written down ... imortalized Now. ... spread your net ... to catch them ... to persuade them ... to be imortalized

My plan for today is marking students exams. Boy ... there's too many distractions. I've got these new musical DVDs. I took sneak preview of those. Oh boy, they are so good that I want to watch them right now. Then, I wanted to update my blogs. There are so many ideas floating around. I've got to capture them and write them down before they run away. Then, books and stuff I wanted to read. Things I want to do (like cleaning up the pile of stuff in my desk). Grrr... the timing is so perfect! Like they know that I have to work. Now they tease me. I just can't say no to them. What to do?

I have just posted in my other blog a question on hazard sign usage. Some people here use it to indicate that they want to go straight. The logic is something along this line; if you want to turn left, give a left turn signal; if you want to turn right, give a turn right signal; if you want to go straight? ... turn left and right at the same time. Turn the hazard lamp on! Wow??? No, I am not joking. After asking around, some people think that this is a correct behavior. That's what they were taught by their friends and family. They never bother reading what's the correct usage. (Hey, is there such manual?) So, be careful when driving in Indonesia.

What did I do in 2009? In terms of academic stuff, my students and I produced 5 papers. I wrote 2 books. Not bad. Here are the papers Budi Sulistyo, Budi Rahardjo, Dimitri Mahayana, On Applicability of Chaos Game Method for Block Cipher Randomness Analysis, International Conference on Electrical Engineering and Informatics, Volume I, Selangor, Malaysia, IEEE Computer Society, August 2009. Budi Sulistyo, Budi Rahardjo, Dimitri Mahayana, Carmadi Machbub, New Methodology of Block Cipher Analysis Using Chaos Game, submitted to ICT Journal, ITB, 2009. Budi Sulistyo, Budi Rahardjo, Dimitri Mahayana, Carmadi Machbub, Randomness Analysis of Block Cipher Using Chaos Game Method, International Conference on Rural Information and Communication Technology 2009, ITB, 17 June 2009.

Everyday my other blog ( rahard.wordpress.com ) is visited by more than 1000 hits daily. Currently, it has reached 1,999,079 hits. Well, tomorrow (hopefully) it will reach 2 million. Who will be the lucky person? (as if it is that important. ha ha ha. but, still... 2 million is not a small number. I am kinda proud of that blog.)

I have just opened my gmail mailbox using firefox and I was refused with an "untrusted connection". It is said that the site is untrusted and that the certificate is invalid. This is strange. I got scared. I was afraid that I typed the wrong URL (address) and got a malicious site. Phishing? After browsing the internet I found out that the problem is with my system clock/date. When I booted the computer, it went to the CMOS setup (for some reasons). I guess I have to replace the CMOS battery. Anyway, I got my computer (Windows XP) to boot up. I didn't realize that the system date was messed up. It was set to 2006. (Now, it's 2010!) I corrected the date and time. Everything is fine now. Firefox and gmail are now happy. Phew ...

Today is the first Monday of 2010. It's not bad. In fact, it is a great day. So for those who don't like Mondays, perhaps this is an exception. I don't like Mondays ... :)

I have just got a song book from a friend. It's a copy actually. But, what makes this song book so interesting is that all the songs - 400 of them - were written by hand! I am not kidding. By hand! Here's a picture of it. I am enjoying the book right now. Reading the songs one by one. They are popular songs in the 70s and 80s, so I know most of them. Right now, I am adding chords to the songs. This book inspires me to do a similar thing; collecting lyrics and chords of songs that I like. It is difficult to find songs that I like in one book. Most of the songs I like are not common :) Thus, I am on my own. Hmm... let me find time to do this personal project.

Reading somewhere, I was asked to add this blog to feedburner(.com). To be frankly, I am not familiar with feedburner. So, I followed the instruction and add this blog to it. Since I have just added the blog, there's not much I can do. I wanted to analyze and optimize this blog. I'll wait a few days to see how this one goes. In the mean time, let me read all the docs related to feedburner. In any case, here's the feedburner feed http://feeds.feedburner.com/gerakanbawahtanah and my other blog http://feeds.feedburner.com/budirahardjo So, what can you do with feedburner?

Happy new year ... This is my first post in this blog in 2010. I hope that this year will bring happiness to all of us. Now, let's start the day ...
