Glad

Yesterday I met up with my old pal. It had been around 3 years since the last time we met in 2011 at Bandung. She hasn’t changed a lot. Still cheerful, sincere, except her cheek is now slimmer :). But that’s what I like from her. Albeit huge traffic jam at Jakarta last night, we traveled from her office at Simatupang to Lotte Shopping Avenue to find something to eat as dinner. We shared a lot of stories about our work, our new friends, our other friends. Some more things I know about her last night are she likes Lego Nanoblock and Lychee Juice. For the last item I’ll try to bring her one next time.

Glad to meet you again Gladys. Hopefully we can still meet up again with others. Diedra or Ari or Marsha.

Cheers.

Grateful

I feel extremely grateful today. I’ve just arrived at home and abour 30 minutes ago I got a very huge miracle from God. So here is the story. I just bought a new Reebok running shirt using a discount voucher that I obtained from last week marathon event plus 2 retail vouchers of MAP that I received from my office event last Monday. Using all these vouchers, I just needed to pay IDR 10 thousand more to complete the purchase. What a great buying. And I happily went home by taking busway. However at bus stop of Harmoni I accidentally left my new shirt on waiting chair. And I just got realized that I left it behind after I got home. So I asked my father to escort me back to the bus stop and I rushed toward that exact waiting chair on which I had sat before. I found nothing. I walked toward security desk and informed the security person about my case. He helped me to find again my belonging. We walked across that huge bus stop and I happened to see a man holding the exact shopping bag of mine with Reebok picture on it. I hastily rushed toward him and asked whether he found the shopping bag from the waiting chair. He seemed nervous and we all know that if I didn’t find him, he would had brought the bag away. He handed back the bag to me and I said thank you quickly to him. I talked back to the security guy and I informed him that my shirt color is blue and we saw together into the bag and yes it’s super blue. So he believed me and warned me to be more careful next time.

So firstly I really want to say thanks to God that He has blessed me and still allow me having that new shirt. Hopefully this shirt can accompany me during my running or work out activity in near future. Thanks God!!!

Moral of the story : Always look back when you leave anyplace.Be-Grateful

Hatred

God teach me to cleanse my mind from the hatred.

No matter how people try to ignite my anger, guide me how to resist it.

Let my mind be at serenity and my acts follow your path.

As You always teach us to love each other, as You always forgive everyone who wants to repent. Teach me the same wisdom to follow your path.

I will not let this hatred ruin my strive toward glory.

The Women, the Busway and the Pain

Holaa,, after 2 years I didn’t update this blog, today I found several things I want to record here. I started today with a stint of pain on my knees. This was the after-effect of my first 10K marathon run with 2 college friends. Here is a snapshot of my small triumph last Saturday night:

IMG_20141109_200209

Forget about the IronMan pose in the middle. It was just a headlamp that luckily fitted my chest (which means I need to build more muscle here ). Anyway,, today I had a full day sharing of joy of marketing team. I’m not part of marketing team, but I’m invited anyway :). Despite the pain, I really enjoyed the activity today at a restaurant inside Ancol. And during this activity I found 2 women that mesmerized me. We departed by bus from head office at 8.00 a.m and I happened to sit right beside this woman. Well actually she happened to sit next to me because I sat there first. We sat together at the back of the bus. And she introduced herself to me. I hadn’t met her though, until today. I’ve heard about her that she moved to her current role to replace a senior employee who moved to other office. This woman caught my attention in a way that has never been shown by other introduction of other women I’ve ever met. She asked me first about my current role. And then she asked me where did I graduate from (which, I believe, is a common question in my office). Moreover, she delved more into further details such as where I spent my high school, where I live, and even my primary school. It’s not that I don’t like her questions. I didn’t find it annoying either. No, not at all. But I was just astonished that this woman asked me that details in our first encounter. In fact I’m quite happy, knowing that someone want to know you more :). I enjoyed the conversation with her. It was sincere and very natural. Hope we can chat again next time :).

The other woman that amazed me today is my marketing peer. During the sharing of joy activity my marketing peers performed to be a girl band. And one of them really really has an outstanding voice. Jaw-dropping. Too bad our team didn’t win the tournament, but we were selected as the most favorite though :D. I believe she could make her fortune by joining a singing contest.

That’s all for the women. Now about the busway. Yeah, today evening Jakarta was filled with huge rain. I got trapped in my office during the heavy rain so that I ordered foods to be delivered to my desk. When I decided to go home using busway  the traffic was so horrible. Especially at Roxy where there was a deadlock at the intersection (It’s been several times happen every time I go through here). It took 5 times of green-yellow-red cycle and no vehicle movement at all during about 15 minutes. This aggravated my pain on my knees because of course I stood inside the bus. Oh Jakarta, when will your mind-boggling traffic jam issue be solved? That’s why I hope one day I could move to more peaceful city where traffic jam is a not at its dictionary :). Amen.

First Month of Internship

A lot of things I’ve learned during my first month of internship at Unilever. Mostly I learned about supply chain, a division where I’m currently being assigned. But what’s important too is I learn about friendship. ULIPers, they said, but I prefer to call them my comrades. A lot of people have helped me since I joined this internship. From showing me the structure of organization to simple thing such as using office printer.

However, the fervent vibe exists when we gather together; being it lunch at canteen or having dinner and watching movies. The exchange of laugh, joke, or story or even gossip, all mix to be a great chemistry among us. Up to this time, three of my ULIP friends have finished their internship. I’m glad to have Marvel, Aris and Cheryl as my friends here. No, not just here, I believe we’ll be friend for a long time ahead.

Still, I have 2 months ahead of internship and I know I have a great group of ULIPers I can’t forget for the rest of my life.

Rogers pcb board

My final project requires me to use a RF PCB board which is not available to buy in my country (as far as I know). So I decided to order it from one of the most known PCB manufacturers, Rogers Corporation. The project I’ve been worked on (Doherty power amplifier for LTE base station) is based on NXP LDMOS power transistor. From many application notes I read from NXP websites, they use Rogers PCB too. So, I choose to adapt their PCB selection and my option goes to Rogers 4350B.

Rogers claims in its datasheet, Rogers 4350B has a very good microstrip insertion loss which is shown in great detail here:

chart3

At my power amplifier operation frequency (1.8 GHz), the loss is about –0.05 dB/in. Compare this to a FR-4 PCB (which is very easy to find) that has –0.15 dB/in loss. So I’m quiet sure that my decision is correct.

At first I got confused about how to order it online. Together with my lecturer, we tried to find it from DigiKey but we couldn’t find any. Several days later, my other lecturer suggested me to order it directly from Rogers website. I browsed the site and I found a part where we can order a sample (free). Then I found this University Program from Rogers that requires us to register our University in order to get a sample for University academic purpose. So I began the registration process online. The response was pretty fast. At exactly the same day we registered, my lecturer got an e-mail from Rogers Corporation at USA with the order number already. Wow. Later on we got e-mail from Rogers subsidiary at Singapore (I think because its closer to my country). Hence, we contacted this officer from Rogers Singapore about our order.

I asked the officer when will our order be ready to be delivered. He said that it requires about 10 days for the PCB board to be manufactured. Wow, that must be a very state-of-the-art one. After almost 2 weeks waiting I contacted him again about our order. Then he said we need to send a DHL account for them to ship. At that time I think it’s not a difficult task to find any DHL account in my campus. I was wrong. It took about 5 days for me wandering around ask any people I know about DHL account. None of them has it. OK, then I asked the Rogers officer whether a FedEx account can be used. The answer was yes, so I immediately send him the FedEx account I got from my lecturer. It was Friday evening that made me think the order would be processed the next day. I waited till Tuesday and tracked my order through FedEx web, and I got it had been processed since I sent the FedEx account. This a great response from FedEx. Finally my order arrived at Tuesday (from California on Friday evening) and it was packaged really nice. Thank you Rogers for sending us the sample. Thank you FedEx for the extraordinary delivery service. Now what I need to do is to deal with whole implementing stuff with this Rogers PCB in order to finish my final project.

Game Theory Course

This idea has been lingering in my mind since the beginning of this semester. During the last holiday (January) I watched a lot about Game Theory course in online videos from Yale University. They provided the videos freely at youtube. If you want to watch it there, you can watch it here

I strongly suggest to watch it directly on youtube for larger view or you can download it and watch on your video player. I did the latter in order to get the best audio of it.

There are totally 24  videos you can watch with each video having 1 hour duration. I haven’t watched all of them, and I also skipped about 3 videos, but I think it’s better to blog it here. The reason is because I find out that this course is really useful whatever major you come from. It’s quiet fun and will make your life brighter in decision making.

All contents of the course belong to Yale University (I’m not Yale’s student, I’m just someone who watched the course from Open Yale Course program) and you can check it at http://oyc.yale.edu/economics/econ-159. The lecturer of this course is Ben Polak (picture shown below) who is an expert on decision theory, game theory and economic history. I don’t know him personally but I think his style of teaching is very understandable.

The content of the video that I’m about to provide is really what I perceive from watching this video. I will try to be as objective as possible in delivering the material. Should any of you come from Yale and took this course (or perhaps participated on the videos), feel free to give any correction if you find any.

So let’s start the journey. The first question that may ring in your mind is “what is game theory?” Well, Ben said that game theory is a method of studying strategic situation. So what is strategic situation? Ben mentioned the example of non-strategic situation of economy (this course is taught at Economic major but it’s applicable in many parts of our life) about perfect competition in which firms (companies) don’t have to worry about what their competitors doing. Monopoly also an example of non-strategic situation because monopolist doesn’t have any competitor to worry about. But when we have imperfect competition that means we have strategic situation in which the decision taken by a particular company depends on what its competitors do or might do. A good example is Ford must be worried of what GM is doing and what Toyota is doing. Indeed many businesses in the world are in the form of strategic situation. So to put it on more general meaning, strategic means a setting where the outcomes that affect you depend not only on your action alone but also on action of others.
