Challenging a Danger

Easy and cheap transportation is the most favourite choice for the people in my country. One example is busway. This is the most favourite public transportation for the people living in Jakarta. As you can imagine, the simple and cheap transportation will become the favourite one and as the result, passengers will fulfill every space in the bus.

Another favourite public transportation in my country is Jabotabek train. This kind of train serves from south of Jakarta (Bogor) until Jakarta-Kota, and also serves from Bekasi until west of Jakarta, making people easily move from those areas to other areas in Jakarta. Well, in the early morning of Tuesday on September 28, 2010, I have a duty to Bogor to interview a professor. The story about this will be written later... :) .

So, for the first time during last five months, I stepped in Depok Baru Railway Station. The passengers are so crowded waiting for the train to Jakarta-Kota and Tanah Abang. I have no wonder about this since today is working day until the officer in the station gave an announcement of the coming train from Bogor. This made me fascinated! The train were full of passengers even they had to sit at the top of the train and also hanging on the handle bar near the train door. This could be done only for the 'stunt master' for TV or film show... :) . And if you see this in your TV, there could be a text 'Don't do this at home' to remind the people not to do this.

As you can see in the picture above, that would be the profile of our public transportation nowadays. So what should we do to solve the condition like this? Any opinion?

Some People Reach The Top of The Corporate Ladder Without A University Degree

The statement above I quote from bonus magazine of Jakarta Post I borrowed from National Institute of Health Research and Development (Litbangkes). The magazine is Weekender, October 2010 edition. On Friday September 24, 2010, I borrowed this magazine from local library in my institute, so I hope I could read the magazine in my office while I was working with my daily activities. The magazine comes with many topics to read, but this topic seems the most interesting topic for me.

I don't mean that I have reached the top, but I mean most of the people today have a vision that being success will be reached by having higher degree. You may have a closer look at your surroundings. Some people reach success even though they don't have any university degree.

And, some people -unfortunately- have a look on someone by his or her degree. They will spread a red carpet if you have higher university degree. They will welcome you kindly. On the other side, if you don't have anything, you will be nothing in their visions.

And, this is the point of this writing, life is changed. Don't underestimate on someone.

First Trying of BlankOn v6.0 Ombilin

Today Tuesday September 14, 2010 is my first trying of another Linux variant. This variant is from Indonesian. Very unique in my opinion since it uses a name from common Indonesian tribe namely Javanese, Sundanese, Balinese, Madurese, etc. This Linux is BlankOn v6.0. This version of BlankOn comes with the name code Ombilin.

According to documentation, this BlankOn is derived from Ubuntu, so you can try BlankOn using Live CD without needed to change your computer settings. Another interesting side of this Linux is the use of Indonesian Language for most of the application menu, but not of them. Hmm, actually this would make me confuse since in computer application some people are familiar in English language. But this is not a big problem. If we use Indonesian language more often, so we will familiar. We just need a time to get adaptation.

Anyway, if you want to try BlankOn, you may download via this linkhttp://www2.blankonlinux.or.id/unduh/. Don't forget to prepare a space in your harddisk or flash disk for about 700 MB. After that, you may burn the downloaded iso file into the CD using Nero. And... a Live CD for BlankOn is ready.

Please underline that this posting is written using Live CD of BlankOn Ombilin version. Good job! Alhamdulillah.

Sesuaikan Etika dan Busana Anda dengan Lingkungan Masjid

"Sesuaikan etika dan busana Anda dengan lingkungan masjid".

That statement is quite common in our surroundings especially when we enter yard of a mosque. Some mosques warn visitors with such a statement I quote above. This is the second mosque I know having such a statement to remind visitors to adjust their clothes based on Islamic rule, at least to cover their 'aurat'. Please refer to Islamic book concerning about this, you may find it easily in your local bookstore.

The first mosque I know having a statement like that is Al Azhar mosque near Blok M area. The statement is written in such a big font size that everyone can see the statement clearly from a distance. Alhamdulillah, in Ramadhan 1413 H/2010 M, I found similar statement qlued on a wall in Al Maghfiroh Mosque around South Jakarta. Well, in my prediction, there would be a lot of mosques having a statement like that to remind visitors to adjust their clothes based on Islamic rule. What about the mosque in your surroundings? Has the management of the mosque (DKM or Dewan Kemakmuran Masjid) already warned their visitors? If not yet, why don't you advice the management about this?

Hmm, I guess there would be a growing number of mosques that will have a statement like this. Alhamdulillah, all praise is to Allah. I also remember that in some Islamic boarding school (pesantren) have similar statement like that, but in 'stronger' statement since they -perhaps- have more power. They remind their visitors with a statement like this:

"Anda memasuki kawasan wajib berbusana muslim/muslimah".
(You enter compulsory moslem/moslemah-dress area).

Installing ClustrMaps for Buku Islam Blog

September 05, 2010, I installed a blog tool to know location of Buku-Islam blog visitors. The tool is provided by ClutrMaps. It provides a geographical location of where our blog visitor come. Pretty useful.

Something to underlined that ClustrMaps doesn't provide a real time report, but it will update the report daily. So the image report we see is actually the description of visitors for the last 24 hours.

Below I captured a report from 5 Sept 2010 until 6 Sept 2010. So I only get description based on 24 hours basis. The report says that Buku-Islam blog visitors come from all over the world. Alhamdulillah. Most of them are from Indonesia and some of them are from United States. The rest are from many other countries namely Saudi Arabia, Japan, Qatar, and Morocco.

Well, this ClustrMaps is a very interesting tool, especially based on my humble opinion.

Indonesia's 65th Independence Day Commemoration

August 17, 2010, today is a special day for my people. Today is our country's Independence Day commemoration. We have celebrated this Independence Day for 65 times.

Being an occupied country is painful. And now we live in independent era since -actually- our nation can do anything without order from other nation. This idea always keep in my mind. Are we actually independent? Independence in my humble opinion is no control from other nation, and we can control ourself.

I don't want to create a list that our nation is being controlled by other nations. You may think by yourself. After that you may conclude your opinion. Please don't be so extreme, since you are Indonesian. So love your country, Indonesia.

National Lokakarya at Horison Hotel Bandung

Alhamdulillah, in the name of Allah, I found an internet connection, because my modem was left in Jakarta.

From August 05-07, 2010, I join Lokakarya Nasional at Horison Hotel Bandung. But I don't want to talk about the Lokakarya since it is too serius. Let's find something joyful... :). It is rather difficult for me to find out what the unique thing from Bandung. What is something special from this city? Yup, I also asked my friend about this. But the answer is just joking.

Peuyeum. Maybe. But I am not interested in it. Hmm, I like Bandung Railway Station. Yup railway station. Maybe tomorrow, I will tell about Bandung railway station.

Hmm, it is already late, 21.42 PM. Tired.

Semarang Tawang Railway Station

Sunday August 01, 2010, the condition forced me to go back to Jakarta using train. Formerly, our plan was going back to Jakarta using airplane from Ahmad Yani Airport Semarang. Well, well, well. So our destination was to reach Semarang Tawang Railway Station. Alhamdulillah, I am very familiar with the condition around Semarang, since I had ever studied in Diponegoro University for years. And, train was my main transportation from Jakarta to Semarang.

The situation of Semarang Tawang Railway station is not changing much. I like the old building of this station which was created during the era of Netherlands occupation of Indonesia. The architecture is very unique. It creates a unique sense different with modern building. Well, I love it.

Hmm, I still remember 'my favourite transit', the mushalla. This place is the first destination when I reached Semarang after having travel from Jakarta. Yup, going to pray. Or, if I reached Semarang in the early morning, this place was my lovely place while waiting for the sunrise and continue my travel to Tembalang. Yup, waiting for praying subuh and for the sunrise.

Semarang Tawang Railway Station really has an interesting memory for me. Someday, I will travel and show this station and the memories lie behind this station to my beloved wife. I will show her my lovely memories...

The participants of the exibition come from many institutions; goverment institutions, private company, universities, and even many schools. I will write about something interest later, about Batik. But later... I have to do a scout first (like gathering information about something).

Linux From USB Flash Disk

Something that attrack my attention about Linux is running it from flash disk via USB port. On Friday June 18, 2010 I tried to emulate Ubuntu 10.04 to flash disk. Alhamdulillah, it worked. So that I can run Ubuntu from USB flash disk. The way it works is similar with running Linux from a Live CD.

So this is the way you do if you want to run Ubuntu from flash disk:

1. Buy a 2 GB of flash disk. This is the minimal size.

2. Get Universal USB Installer.

3. Download Ubuntu iso from Ubuntu site.

4. Place Universal USB Installer and Ubuntu iso on your computer in the same folder.

5. Run Universal USB Installer.

6. Follow the wizards.

That's all. Pretty easy huh?

:)

This trick may be the solution for the computer who cannot run Ubuntu Live CD. Because I have the same problem with this. Formerly I ever tried Ubuntu Live CD to run in my laptop. But my laptop get freezed during its loading. And using this trik I can run Ubuntu well on my laptop.

So do you want to try?

First Trying of Ubuntu in Networking

Today June 03, 2010 I try Ubuntu 7 (Feisty Fawn) that I get from Bogor when I attend computer networking training. I try this Ubuntu in my office computer that is connected to a network and also connected to the Internet. I know Ubuntu a few years ago, but this time is my first experience trying Ubuntu in a computer network.

One thing fascinates me. Ubuntu can detect everything including a network that already exist. So everything is easier. Using its live CD I can PING to Google and try to connect to any sites I want. So this could be my first post using Ubuntu in LIVE CD and in a network. Alhamdulillah.

Reach 10.000 Visitors for Buku-Islam in Three months

Alhamdulillah, my blog http://buku-islam.blogspot.com by June 03, 2010 has reached 10.000 visitors since I installed the counter on February 24, 2010. So, it needs three months to reach such a amount visitors.

What does this sign mean? For me, this is only my prediction that could be right or wrong, there are good antusiasm among people (Indonesian people) in searching Islamic knowledge. Especially, the knowledge about basic of Islam.

May Allah be with us and preserves Islamic da'wa in Indonesia. Amin.

A Trip to Puslitbang Gizi

On Saturday March 03, 2010 I went to Bogor to Puslitbang Gizi. It is not a formal visit but just to fulfil my curiosity where the Puslitbang Gizi is.
So I went to Depok Baru Railway Station. I love having a trip by train. I chose economy class train in order to gather with ordinary Indonesian people, 'the proletar' by my term. And with another reason, to save my money... hehe.

Finally, the train reached Bogor Station. Railway station has a very interesting sense for me. I don't know why. The architecture is different. Perhaps because most of the railway station in Indonesia was built by Netherlands Government during its occupation.

I was lost of direction when locating Puslitbang Gizi. But after asking to some people I found it. The situation around Puslitbang is good. I like the environment. It is different with the situation in Jakarta.

In my opinion, Bogor is a good place for living with family.

R Table Failed to Generate

I woke up early morning today. After praying Shubuh and doing some activities that I must do in the morning, I boot my laptop with one purpose, to generate R table (This term is only from my self). This table is needed to crack a password. Hmm, I don't actually know the different between R table with dictionary attack. But, some literatures said that cracking using R table is more powerful.

There is always a building block to achieve a goal. And I realize it. Generating R table is not easy. At about 6 AM in the morning, I started to generate R table. After calculating using Benchmark, it needs 6 to 7 hours to generate. So I started to generate this table. And I left my laptop for another activity, going to AHASS to repair my motor cycle. But, when I went back to my laptop, it is already shutted down.

Then I tried to build R table for the second time. After for hours of generating, my laptop was shutted down again.

So, my conclusion is I need a cool room with AC to reduce the heat produced by my laptop. Because the laptop will work for almost 7 hours to generate the table. This table is for cracking a password with 80% success rate. If I want to crack a password with 99,90% success rate, I have to generate much more bigger table with the size 122.07 MB. But, to generate such a kind table needs 9.6 days to generate. So I need cool place and a robust processor....

Found Interesting Password Tool

Today I found interesting password tool. Very interesting in my opinion. This tool is used for generating a list of table.

So a new way to crack a password is open.

Psst..., don't tell anybody... :)

Whoever Save ONE Life Save The World ENTIRE

Today I enter a new phase of my life. Monday March 01, 2010. I just remember a verse from Holy Qur'an. Allah Jalla wa 'Ala says (in Indonesian):

"Dan barangsiapa yang memelihara kehidupan seorang manusia, maka seolah-olah dia telah memelihara kehidupan manusia semuanya." (Holy Qur'an, al Maa-idah: 32).

I remember that I often quote this verse. And I write in my book...

"Whoever save ONE life, save the world ENTIRE".


My Allah be with us. Amiin.

A Doa to Remember

A few days ago I went to an Islamic Book store at Margonda Street Depok Indonesia to look for some books. As usual this is my monthly activities to fulfill the need of Islamic knowledge. Alhamdulillah.

And I found an interesting book. A new relase book from Pustaka at Taqwa. The title is "Ruh Seorang Muslim Tergantung pada Utangnya". Yup, since it is an Indonesian-language book. So, I read the book for a glance to know the whole content in single sitting.

Then, my eyes were glued on an interesting and heart-touchful doa. Alhamdulillah, I felt that I am a lucky man because I found this doa. This doa is from a hadith. So here it is,

"Ya, Allah, cukupilah aku dengan rezeki-Mu yang halal (hingga aku terhindar) dari yang haram. Cukupilah aku dengan karunia-Mu (hingga aku tidak minta) kepada selain-Mu."

(From at Tirmidzi (no. 3565) and Ahmad (I/153) from 'Ali bin Abi Thalib radhiyallahu'anhu. It is stated that the hadith is Hasan).

It is a good idea, very good idea to keep this doa always in our mind.

Happy Chandraleka on Google Search Engine

Januari 06, 2009. At the campus I tried to type my name in Google search box. In Google Indonesia www.google.co.id. I was wondering with the result as we see in this screen-capture. There is 13.400 result for the keyword 'happy chandraleka'.

Then I tried to do the same thing with Google Russia (www.google.ru) and also Google Japan (www.google.co.jp). But the result is different. So, it only works on Google Indonesia.

Most of sites that record my name are sites about bookstores and library (university or institution library). But don't make any mistakes with other names.

It means nothing by writing this article, since it is only my note on the net as I mentioned above in this blog.

Mata-Mata keylogger on Brothersoft

Just fulfilling my curiousity, I tried to search my interception tool Mata-Mata on Google search box. Something wonderful is happened. It was beyond my hope. I saw the program that I created a few years ago. This program is called Mata-Mata v2.0 that developed under Delphi programming language. A program to intercept any data entered via keyboard. And also this program will record interception result into a file called log file which can be sent into an email account. Hmmm, so yummy... :)

Well, that's about Mata-Mata, a spying tool. But something that makes me so surprise is that my program can be downloaded on Brothersoft on this link www.brothersoft.com/mata-mata-keylogger-261031.html. Actually I forget when I uploaded this program. And today I found that this spying tool is already available on Brothersoft. Well done!

According to the information provided on that site, Mata-Mata v2.0 has already downloaded by 345 user all over the world since it was available on July 15, 2009.

Sequence for Windows Dual Boot

The sequence for creating dual boot on your PC.
First, you have to install Win XP on a harddisk partition.
Second, you have to install Win7 on other harddisk partition.

That's what I did on my laptop a few days ago.

So my conclusion is for creating a Windows dual boot is you have to install the old version of Windows first. After that, you may install the new version of Windows.

Bus Way Passengers and Metromini Passengers

On Monday I went to Rasuna Said by Bus way. Actually I do not often go anywhere by Bus Way. But that day was different. As usual, I always pay attention at the condition around. Hmm, I have my own 'wise words', 'watching life through a rifle scope'. Meaning in Indonesian, 'Mengamati kehidupan dari teropong senapan'. But actually it is not from 'a rifle scope'. Well, just watching ar0und...
By doing this I hope we can learn something new from others.

That day, I paid attention at passengers of bus way. Passengers of Bus Way mostly come from The Have. We can know from the way they get dressed. Their uniform, their clothes, their bags, etc, represent the level of social life they come from. Hmm, even some of them took out their handphones from the bags or pockets. Waw, high class social life might reflect from their sophisticated devices. Hmmm, mine is quite 'jadul' (jaman dulu). Oh yes, I almost forget, I saw a passenger playing electronic games using electronic device. I didn't know the device, maybe PSP, Gameboy, or ... well, I am not expert in this field.

Different case with the passengers of Metromini or Kopaja. Like The Earth and The Sky. In Metromini it is often that we saw passengers still using 'sandal jepit'....
Hehe..., if you want to know about high class brand, try using Bus Way. Maybe it is a good stepping stone for you to learn ...

Seminar About Steganography and Cryptography

On Friday October 30, 2009. As a speaker on seminar about 'Introduction to Steganography and Cryptography'. The seminar was held at Fatmawati, Jakarta. About 90 students joined in this seminar.

This is actually the second chance. The first chance was on June 23, 2007 with the topic was about Virus, Worm, and Trojan Horse. At this time due to the huge antusiasts of the students, the seminar was scheduled into two sessions.

May Allah 'Azza wa Jalla be with us.

Be Careful when Using Facebook

Facebook has become an Internet phenomenon today. Every young people -I predict- has an account in Facebook. Too bad, I am left behind that I don't have Facebook account -at least- until now. Facebook has rised pros and cons. Many -I think- most of companies forbid their staff to open Facebook since it would decrease their productivities.

Okay, we put aside that point about people who are pros and people who have contras opinion about Facebook. There is a case in Jombang, East Java. A female senior high school student was being kidnapped by someone she knew via Facebook. The details of this story can be read in this link http://www.beritajatim.com/detailnews.php/8/Peristiwa/2009-10-23/47853#.

Based on that story reported by Yusuf Budiono (the reporter of Beritajatim), the girl was making a friend with a man via Facebook. After that this 16-year-old female student went with the man to Bali. Then there was no contact anymore with her family. Of course her family was in terrible sad and very shock (may Allah help them). A source said that the girl has become a victim of human traficking.

So be careful my friends...

Trik Mengantisipasi Hacking Email

In the early of October 2009, my 16th book is published by Media Kita. The title is 'Trik Mengantisipasi Hacking Email'. The book contains about many tricks to advanced our knowledge about email security. Some topics in this book are how to crack an email account, how to find out email header, how to create email forgery, also about spamming, chain email, reading email using telnet, etc.

So have a read...

My book, Mengamankan Data ala Agen Rahasia

Alhamdulillah, just before Eid ul Fitr, my 15th book is published. The title is "Mengamankan Data ala Agen Rahasia".

This book is covering about the way to secure our sensitive document using steganography and cryptography. So, our sensitive documents cannot be revealed or captured by someone else.

This technology (steganography and also cryptography) is already used since the ancient era. Since Julius Caesar, Hitler, etc.

The book consists of a lot of demonstration that you can practice with your own. Very simple demonstration to keep your document's secrecy.

So, if you are an agent like 007 agent, or if you are a diplomat, or if you are a high-rank goverment official, or if you are any body with very sensitive data, you -all- must read this book.

Okay, write down the title and go to the book store now ... :)

Here is The Decrypted Message

My last posting is giving you an encrypted message that might be a puzzle for you. The encrypted message is :

It is a secret message, so we have to reveal the message. Here is the decrypted message, the actual message:

"I LOVE YOU RAMADHAN"

The message is actually encrypted using a very simple algoritm called Caesar cipher which is created by Julius Caesar. The Caesar cipher works by replacing every character into the next three character. So if the letter 'A' in plain text would be replaced by 'D'. Very simple.

Well, that's all. I have something to do since today is (perhaps) the last day of Ramadhan 1430 H. Tomorrow would be Eed al Fitr 1430 H.

An Encrypted Message for You

When we are a child we like to play hide and seek. Hide and seek means 'Petak Umpet' in Indonesian. A child has to close his/her eyes while the others is running away looking for a place to hide. And then that child begins to seek their hiding friends. Oooh, it is so happy to play that game. Espesially when we can find our friends that is hiding in his/her secret place.... :)

Based on that game, I would like to give you a secret message. Who knows that you can find the real message behind it. This is an encrypted message for you all.

"L ORYH BRX UDPDGKDQ"

Next time, insya Allah, I will reveal the real message for you.... hehe. So this is the time for you to be 'a little confused'.

Senapan Serbu Pindad

The picture above is a picture of Senapan Serbu SS-1 taken from http://www.wikipedia.org/. This gun is making a headline in nowadays newspaper in Indonesia. Created by PT Pindad, if I'm not mistaken it is under liscence from Belgia. Based on information from Wikipedia, this weapon is already used in conflict in East Timor, Aceh, and Papua.

Sandiwara Langit

Some friends recommend me to read an Islamic book with the title "Sandiwara Langit". They said it is very good. The book which is written by Ustadz Abu Umar Basyier, is about a story (the book said it is based on true story) of a struggle of young man to marry a young girl. And the young man (called Rizqaan) finally can marry the girl based on a condition. Yah, mereka menikah bersyarat...

I don't actually read the book page by page. I just have a quick read on that book. And my conclusion is the story is really really sad. Wah, gak kuat deh bacanya. Untung aja masih baca sekilas... :)
Yup, I don't want to read for the second time. I have two reasons for this. Because the story is really really sad. That is for the first reason.

But after having a quick read on that book, I have a critic for the story. It is a big question in my mind. Well, no problem. We can skip that one, and this is not decreasing the quality of the book.

Hmmm. Jadi teringat juga orang orang yang berkumpul dan berpisah karena Allah...

Another Indonesian Cyptography Site

As usual, by accident I have found another Indonesian site about cryptography. It contains a lot of information concerning this topic. Well, I am so happy about this. The site is located at

http://hadiwibowo.wordpress.com/.

At the link 'Arsip Tulisan' it consists of 85 articles concerning this topics. Wah, hebat deh. They are ready to study....

Anyway, I found this link after I visit an article written in Manado Post. This is the link, http://mdopost.com/news/index.php?option=com_content&task=view&id=1315&Itemid=9. After reading article 'Menelisik Liku-Liku Aksi Penyadapan dan Ilmu Kriptografi (2-Habis)' in Manado Post, my eyes focus at Hadiwibowo link. So I found another resource. Hmm, just like 'Nuclear Chain Reaction'. Just like 'Domino Effect'. One action will be followed by the next action successively.

Hmm, Nuclear Chain Reaction, Reaksi Berantai Nuklik ...

Finish Writing my 15th and 16th book

Alhamdulillah, this time is a time when I am waiting for the publishing of my computer books. My 15th and 16th books. I have spent my time for about almost 2 months successively in writing those books.

Those two books are already sent to the publishers.

Hmm, . What's the topic for next??
