Orange Ray in Marina Bay
This blog supposed to consist more technical content. But short poem for my wife should be ok written here. Technical guy also human, right? :)
Smile is like a white pearl
Sincere smile is like white beautiful pearl from deepest ocean
Sincere smile is you
Sincere smile is like white beautiful pearl from deepest ocean
Sincere smile is you
Cheerish is like a sunrise in Marina Bay
Looks so pretty start with its orange rays
End with ultraviolet white light which comprise 7 colors like we've seen in rainbow
Cheerish is you
Looks so pretty start with its orange rays
End with ultraviolet white light which comprise 7 colors like we've seen in rainbow
Cheerish is you
Sadness is like a blackhole in outerspace
It sucks any happyness nearby
It sucks any happyness nearby
Loneliness is like message on paper inside the empty bottle floating on the sea waiting to reach its recepient where sometime never reach at the end
Loneliness is unreplied message
Loneliness is like a husband who waiting to know where his wife when her home
Without any suspicuosness at all
Merely just want to care and to be cared
Loneliness is unreplied message
Loneliness is like a husband who waiting to know where his wife when her home
Without any suspicuosness at all
Merely just want to care and to be cared
Distance is like a knife
Can be good mostly can be bad
Can be good mostly can be bad
I don't want distance will stab us
Mature is not the matter of age
Neither the matter of how many times someone prays per day
And this stupid poem is written by a man who try to be mature
But often always failed
By a man who try to be more gentle and patient as a husband
Neither the matter of how many times someone prays per day
And this stupid poem is written by a man who try to be mature
But often always failed
By a man who try to be more gentle and patient as a husband

My First Toastmaster Prepared Speech: "Programmer that Supposed to be a Teacher"
This blog should be consist most story about software engineering field. But software engineer also human that should have good communication skills. That's why, the last two post of this blog is about public speaking club, toastmaster.
Yesterday I just presented my first prepared speech at toastmaster meeting. Moreover, it was not just ordinary meeting, but a join meeting. It's mean, more audience, more people, more eyes and ears and ultimately, more reason to more nervous. D*mn, I stand above two choices. To run away from meeting so I can save without delivering that prepared speech. Or I take this great challenge and present the best as I can.
The offer slot of speech already given by my club president since about last weeks. I just said yes at that time without think too much. I have not prepared the speech until the day and I don't have any idea even for the topic. First project speech in toastmaster is about breaking the ice. Usually we introduce ourself to the forum. Tell about our life, our story or our daily activities. Thanks God, yesterday morning finally I got the topic. The title of the speech is, "Programmer that supposed to be a teacher". Yes this is the story about my career and the reason behind that and correlation to teaching stuff. Just for information, I was graduated from State University of Jakarta, the campus that formerly known as the institution which prepare its student to be a teacher.
Ok then, finally the time has come. Yesterday after office hour I straight go to Veteran Building. Actually, it is located in Plaza Semanggi. I still feel little bit lazy to go to the meeting. But little by little I can get rid of that feeling. I arrive at venue, and dankk, there are so many person. Almost 30 attendee. More than usual. Oh no. Scheduled speaker for that evening is me, Hafiz (president of my club, Jakarta Toastmaster Motivators Club), Irfan from Essential toastmaster club and Zilfa (President of Essentials toastmaster club). The newbie on the list is only me.
The meeting started like usual with Table Topic Session. Several participant was called to stage to give short speech from the clue given by Table Topic Master. Even, for the guest that just came for the first time, they can gave very good table topic speech. And finally table topic session has ended with so much good speech.
Next is Prepared Speech time. In I got the first slot. Dankkk. *_*. Speaking is always intimidating even for most experienced speaker. We just need to get around this and turn the nervous that might be rise as energy to deliver a good speech. Oke then, I went to the stage. The light off and the spotlight shot on me. Of course there was no such spotlight. But when you are on stage, even without spotlight all audience have full focus on you. That was what I felt last night.
First project for toastmaster speech allow us to bring small notes. So hopefully we will not lost when give speech. Then by using the small note start the speech with great energy, confidence and cute smile (oh no :p). Then about 6 minutes passed, I said thank you and I heard applause around the room. Oh God, I passed that gracefully. Little bit can't believed.
At the evaluation session I got very positive feedback from evaluator. Sometime feel like little bit exaggerated. But I will use that feedback to improve more again. For the grammar I still have some mistakes. And for the "ahh" and pause filler I still inadvertent say "ahh" and some another pause filler. Wonderfull night and hopefully will continuously motivate me to learn more.

Improving Communication Skill at Toastmaster
Last Wednesday I decided to force myself attend toastmaster weekly meeting. Toastmaster is international club that will help its member improving communication and some leadership skill. This club have so many many branches in many countries and cities. After doing some internet research I found the nearest club from my place of activity is at Nielsen, Mayapada building. The building only 5 minutes walking from my office at Sampoerna building and located exactly in from of my boarding house area.
Actually I really want to join this club since long time. First time I heard about this club was from one of the book that I read. I forgot exactly either Steven Covey's or Brian Tracy's book. But since then, I speak to myself, one day I must join that club. The execution itself, finally just happen last Wednesday. My plan to continue post graduate study and the eager to be a better communicator are several reasons that force me to join immediately.
One of the most important reason why toastmaster really can help us in improving communication skill is its friendly environment. Every members of the club either the new member, old member, experienced communicator and the one who still speak with nervous support so much for our improvement and learning process. There is no intimidating feeling. Even though nervous still exist we can push that feeling into minimum level.
There are several important role for every toastmaster meeting. The first is ToM (toastmaster of meeting) the person who will host the meeting from start to the end. Second is General Evaluator, the person who will give general evaluation to all of the speaker. Third is grammarian, self explanatory, this person will comment about grammar usage of all the speaker. Fourth is timer, this role also essential because good public speaker must be have expertise in time management. Fifth is ballot counter, the role that has to count the best prepared speaker, table speaker and evaluator based on vote from all participant. Sixth, last but not least is "ah" counter, the role who is very unique but also very important, to analyze and make comment of pause filler or repeated word that is used by speaker. Guess what, my first visit to the meeting, I am granted to be a ballot counter. Not too big role, but I feel so honored doing that duty.
At every toastmaster meet up, there are 5 main session. First is opening that consist of description all of the role involved during the meeting and also introduction of new guest that attend. Of course because yesterday is my first visit then I invited to the stage, with other guest to introduce myself to all of the toastmaster fellow. Second main session is table topic session. This session is interesting. The ToM will invite several participant to the stage to give some speech. The person who is invited must give speech that must consist 3 prepared words. Time limitation is 3 minutes. Of course with this method every person don't have any preparation at all and must spontaneously find the theme and speak up. Even though yesterday is my first time, unluckily I called to the stage to give table topic speech. Of course very nervous. Guest what, I get these three words for the speech: girl, relationship and breakup. I feel so embarrassed at the beginning, but at least I can speak up in front of audience. Hopefully can be improved when the time goes on.
Third main session is prepared speech. This is main speech with 7 minutes time limit. The person who will give a speech already assigned before. I just can say, the three person that give prepared speech at that night is very awesome. For every prepared speaker, there is assigned an individual evaluator, beside general evaluoter mentioned formerly.
Fourth main session is evaluation. At this part of the meeting every individual evaluator give comprehensive comment for every prepared speaker. After individual evaluator, later grammarian and "ahh" counter also give comment for every speaker.
Last session is closing that consist of voting for every speaker and also guest impression to the meeting. Again, I have go to the stage to announce the best table topic speaker and evaluator. Also I give comment about the meeting. Of course even though I just attend the meeting one time, I feel quite sure the meeting is very usefull to improve my communication skill.
I think that's all my sharing for now. Hopefully will be another sharing follows.

java.lang.SecurityException When Shutdowning JBoss
We can run following command when starting JBoss. We assume there are already jboss system user in OS.
Stopping jboss actually should be done by running this
But in my system this will Exception in thread "main" java.lang.SecurityException: Failed to authenticate principal=null, securityDomain=jmx-console. This is happen because likely we have enabled the interceptor in jmx-invoker-service.xml file in deploy folder. Then for shuttingdown jboss we should provide some credential that we can see at login-config.xml file in the conf folder.
Actually there still some exception when running this.
and
But after running
I cannot see any JBoss instance that still running. So I conclude that shutdowning has been done correcly. I will check the later issue when have time. Meanwhile those shutdowning command can be put into some script.
reference
# Centos
su jboss -c '$JBOSS_HOME/bin/run.sh -b 0.0.0.0 > /dev/null 2> /dev/null &'
# Ubuntu
sudo -u jboss $JBOSS_HOME/bin/run.sh -b 0.0.0.0 > /dev/null 2> /dev/null &
Stopping jboss actually should be done by running this
# Centos
su jboss -c '$JBOSS_HOME/bin/shutdown.sh -S &'
# for ubuntu
sudo -u jboss '$JBOSS_HOME/bin/shutdown.sh -S &'

This is happen because likely we have enabled the interceptor in jmx-invoker-service.xml file in deploy folder. Then for shuttingdown jboss we should provide some credential that we can see at login-config.xml file in the conf folder.
So the shutdown command should be like this

# for ubuntu
sudo -u jboss '$JBOSS_HOME/bin/shutdown.sh -S -u admin -p admin &'
