Cameron Highlands (18 – 22 Dec)

Click here for more photos.
Day 1: Cameron Highlands was totally different from how I imagined it to be. I had this image of an idyllic farmland with miles and miles of greenery and fresh air. How wrong I was. As I alighted from the coach after more than 9 hours on the road, I noticed that Brinchang Town Central was choked with tour coaches and cars. The air was cold and heavy with the smell of petrol.
The white and yellow hybrid sweet corn is a must try. It is the sweetest maize that I have ever had. The Bird of paradise flower can last for 7 weeks! There are 7 flowers in one bud. After the first flower wither, remove it so that the next one can come out. Each flower is good for a week.

Day 2: Along the mossy trail near the highest peak in Cameron Highlands, I noticed a rope along a metal railing. Why would you need a rope and a railing at the same time, one of them would suffice. But very quickly, I realized the answer – the metal railing is very cold and uncomfortable to use when the weather is cold and wet. The rope is not so cold but the grip is not so firm.
When we rested to replenish ourselves, we had a good laugh at the inflated biscuit packs. My children loved lemon biscuit and we would bring these biscuit with us wherever we go. Due to the pressure difference (we were 2000 meter above sea level), the air pressure inside the biscuit plastic cover caused it to blow up like a puffer fish.

Day 3: From Brinchang to Tanah Rata via Jungle trail number 2, 3 and 4.
Trail number 2 was quite challenging, many a time, we needed to use all fours to get ourselves moving forward. While struggling, the children recalled their Bintang and OBS experience, I felt encouraged by them. My youngest son, in his free spirit manner, picked up a broken branch and used it as a magic wand and started ordering nature to bend over for his family.
Along the way, I came across a step that was higher than normal with a root in front of it. With one foot on the root, I balanced myself gingerly and then leapt across the step. Thinking that I used considerable skill and dexterity to clear this obstacle, I turned around to help my family. Just as I was about to stretch out my hand to my eldest son, he walked across the ‘obstacle’ like a flat ground. I was stunned. I saw it as a problem but apparently it was nothing to someone much taller. Conversely, he may not see any potential problem because it was a breeze to him.

Day 4: Day trip versus night trip
We went to Cameron Highlands by night and returned by day via coaches. I felt more comfortable travelling by day. The most irritating part about travelling by night was the flashes of light that swept past us as the coach sped on, making sleep very challenging.

Before going for holiday, it is wise to check if it is a public holiday in the foreign land. We were caught in endless traffic/human jam at Cameron Highlands.

I had always wished that Singapore could be cooler but my experience with Cameron Highlands proved me wrong. I would rather not sleep on a cold bed, brush my teeth in freezing water, lugged wind breaker wherever I go and have my sleep interrupted by howling wind

Sibu Kelong, 12 – 13 Dec: They should know.

Click here for more pictures. At the Ah You Kelong, we slept on rows of double deckers like in an army barracks. On photograph, it looked more like a refugee camp. I was trying to ease myself to sleep on an upper deck reading the papers. My elder son was sleeping on a bed diagonally across me. As I was about to sleep, I noticed his cousin moving stealthily towards him. From the way he behaved, I could tell he was up to mischief, I tried to stop him and I said in a no uncertain voice not to disturb my son. Unbelievably, he continued. My son startled and shoved him off, asking him to go away in a stern voice.
On another occasion, a young boy dropped his slipper into the sea and unbelievably tried to retrieve it. That got the adults hopping mad as he might be swept off by the waves or bitten by sea snakes which are plentiful underneath the kelong. When I told my daughter about it, she responded, “He did it because he was only a child.”
I was not so convinced until at a casual talk. A colleague asked, “What would you do if you reel in a sea snake?” I was momentarily stunned. I would probably try to shake it off. My colleague was more insistence: What if it clings onto your rod and won’t let go?” Another colleague came to my rescue, “I will cut off the line.”
Well, what is second nature to some may not be common sense to others. Throughout our lives, we accumulate much wisdom and even take them for granted as if others should also know. At the risk of repeating myself, I would make it a point to say my piece to my charge in case they are not aware of it.

Sibu Kelong, 12 – 13 Dec: Green and White Baits

The sea is unpredictable: December is in the middle of the monsoon season and it is supposed to be very choppy. One would imagine a lot of fish taking refuge at the kelong waiting for us to catch. However, this time round, it was very calm. There wasn’t much fish or at least they are not biting. In our last trip, the white artificial bait worked very well, bringing in a lot of Selar. But this time the green bait seemed to work better. To even the odds, I will get those that have alternate white and green baits.

Inexplicable Phenomenon

This morning, I attended a prize presentation ceremony. I observed a rather strange phenomenon – some prize winners not only did not smile when receiving their prizes, they even walked lethargically towards the stage. I would have walked with springs in my legs and beaming with a mega-watt smile.

Poly to Uni

Poly graduates vying for a place in the Uni will compete among themselves, i.e. they will not be compared with the 'A' level students. A module from a Poly is not equivalent to a 'A' subject so there is no meaningful comparison, anyway.
The formula for calculating the weighted average is as follows (info from NTU Briefing for Polytechnic Academic Staff on 21 October 2009):
Poly results 80%
GCE 'O' level 20%

Those without 'O' level, will be disadvantaged and will fall under the discretionary admission category. They need to demonstrate passion, creativity or leadership during their course of study during their interview.

Heart-string Pin-up Board

A suggestion from Chua KC: "A pin-up board for each technology center and named it "Heart-String" or something in this line. This is for Valentine or any congratulatory messages the juniors wish to extend to the seniors or to a group or even to lecturers.

They can decorate the board with the messages, etc. The graduation magazine or video committee could then pick some of these good congratulatory messages and publish them. The committee can then go round and look at the messages in the later part of the semester. It is something that they look forward to when they come back for the graduation party too."

NP Dragon Boat Regatta ’09

Click here for more pictures.
This morning, I woke up with an aching back and it reminded me of the NP Dragon Boat Regatta ’09 at the Kallang River yesterday (15th Oct). The staff category was won by the Admin team (principal was in it). Truth be told, they trained weekly in the actual venue for one whole month under an experienced coach while most of us trained only once in the swimming pool with just the paddles.
I am not complaining my point is if one wants to win badly enough, one must put in the resources and commitment. NYP has been very impressive in skill-based competitions because they have the resources and coaches who have participated in the contests themselves and therefore have the experiences to share. The next best thing for us to do is to tap on our own participants and make them share with their juniors so that their experiences will not go to waste.
Before the race, I set a target to win the heat and let others (we have a fair number of reserves) a chance to row in the final. It was not that I was that gracious; I just could not recover enough to race again in such a short time. I was happy to achieve the target.
The last time I dragon boated in Kallang River was four years ago. In the heat of the race, water was splashing all over the place and I was grasping for air, inevitably I swallowed some water. I vividly remembered the extreme taste of saltiness. It was the same this time round, I again swallowed some water. But to my surprise, the water was not salty anymore. The desalination process at the Marina Barrage is really working.

Netriders Challenge Singapore '09

Click here for more photos.
First the good news, NP student team 2 led by Qi Feng came in third in the student category of the Netriders Challenge Singapore ’09. Although we did not win in the instructor category, it was a very good experience for us: it brought the four instructors and the 15 participating students from NP closer together. Ultimately it is all about the human network.
My students posted me this question: “Will NP host the event next year?”
I would like to but we can’t. The event attracted more than a hundred contestants and yet NYP has enough desktops for all of us and still have one room (easily twice the size of our lab and filled with computers) to spare. We just don’t have the capacity. Purchasing PC is a very sensitive matter and it triggered many alarms since every NP student is supposed to have a laptop. NYP was able to justify their purchase because they need to use very expensive software like Oracle. Their director is also very supportive too. He is well known for dropping in on the NYP rep during training to chat with them and solve their problems and needs personally.
I like the story that the MC (NYP staff, Scott) shared about the analogy between the Gold Rush and the Internet Bubble. During the Gold Rush, only a handful of people become rich looking for gold. Many more become rich selling axes, clothes and providing lodgings for the gold diggers. Likewise in the Internet Bubble, many companies went bust but Cisco Systems, the company known as the plumber of the Internet not only survived but thrived.
The story was a smooth introduction to the company that organized this event. Plumbers in countries like England and Australia are making good money; Cisco Systems has every right to be proud to be the plumper of the Internet. I am also very impressed with the ITE staff. I could see many of them either competing or supporting the event like taking pictures, rallying around their students and even giving lecture on Packet Tracer 5.2.

Quote from the 2nd runner team, NP Team 2 Captain, Chan Qi Feng:
“ I thank Mr Lau Wah Kee, Mr Low Chee Kin, Mdm Kannathal and Mr Sunil for their utmost support for our team. I am proud to lead my team members: Tan Deneng and Ng Zekai; they are very knowledgeable and co-operative. In fact, I thought my team could have achieved more but the other competitors were stronger on that day and I congratulate them. I would also wish to thank Cisco Systems Singapore for giving us this opportunity to showcase our talent, bringing back the trophy and joy for Ngee Ann Polytechnic.”

Quote from NP team leader, Mr Low Chee Kin, Electronic & Computer Engineering | School of Engineering
"The Netriders Challenge Singapore ’09 was a great learning opportunity for all who participate in one way or another. As one of the organizers and competitors, I was very impressed with Cisco System’s sense of social responsibility especially in the area of education. It is a joy to see so many industry partners, instructors and students working together to update and sharpen each other. Ultimately, it is all about the human network."
Total Number of Attendees : 200

Study Visit to Malacca

Study Visit to Malacca
(Cubic Learning Factory)
9th – 12th September 2009

As part of my duty, I have the privilege and honor to be part of a 6-member staff team led by Ms Auyong LS to bring 115 final year ECE students on a 4D3N study visit to Cubic Learning Factory (CLF) in Malacca from 9th – 12th September 2009.

9-9-2009 (Wednesday)
In the words of Mr Maniam’s (CEO of CLF) opening speech: “this study visit will enhance your employability because of the overseas exposure and hands-on experience”. For this, we have Ngee Ann Poly (NP) and CLF to thank for.
Before we could begin the factory tour, we have to surrender all our electronic equipment –hand phone, camera, ipod, laptop, MP3 and MP4 players. As we toured the compound, we were awed by its spaciousness: huge warehouse, huge factories and even a university inside CLF. Their students have industrial attachment right inside their own campus.
Cubic engineer, Mr Sik showed us around and related to us his life as an engineer. I am particularly impressed with the followings:
• Mr Sik has not switched off his hand phone since working in Cubic some 8 years ago.
• Production yield target is 99%, if it drops by more 5%, all personnel will be recalled back even for those on leave.
• There is a ‘war’ room to thrash out differences. I will leave it to your imagination as to how it got its name.
• Not a single chair can be found in the production line. A standing operator produces as much as 30% more than a sitting colleague.
• Contract manufacturing: Cubic assembles sunglasses equipped with Bluetooth Technology for a US company. The gadget is a sunglass, headphone and microphone, 3-in-1 package, and retails for a cool US$199 per pair.
• Diversification: One of Cubic factories produces luggage compartments for Airbus. This is a joint venture with a Japanese company.
• Security: Everybody is subjected to security check when one steps out of the factory. Female staff is not allowed to wear metal strap bra or metal hairpin so as not to trigger the alarm when searched.
When we checked into the hotel, we were told that they going to give us different rooms than the ones previously agreed upon. We needed to re-assign 121 people there and then, resulting in a messy congestion at the lobby. To add to the problem, some assigned rooms were not usable – walls, carpet and even the blankets were mouldy and the rooms were filled with an unbearable stench. We only managed to solve all but one by midnight.

Seafood dinner at Sungai Duyong was a letdown. The place was quite a distance from the hotel and it was definitely not worth the trip. Many students did not eat much, preferring to have another meal on their own. Dinner rating: 2/10
The evening ended with a visit to Tamingsar Tower where we spent 7 minutes revolving at the top of the tower overseeing the skyline of Malacca.

10-9-2009 (Thursday)
There was confusion starting from 4am: we have 4 Muslim students and they needed to take their breakfast early because of Ramadan. The food caterer sent the food to the wrong rooms and waking up the wrong people and upsetting many in the process. Apparently, the front desk staff did not advise the caterer properly. The sad thing was that this same mistake was repeated throughout the trip, right up to the last day. As we do not have the updated list for everybody, there was confusion when we tried to contact each other in the morning when we tried to get hold of the late comers.

At the Cubic Factory, there was a lot of waiting and more waiting when the CLF staffs do not know where to put our belongings as we were not allowed to bring electronic stuff into the factory. The room that we used the day before was not available then.
When we were finally allowed into the factories, instructions were passed down to us at the last minute to group the students in fives which resulted in further unnecessary delay – we could have done it while we were waiting had we known the requirement earlier.
After the groups were seated at their respective benches, instructions were intermittent with long pauses in-between either because they needed to fix the PA system or they were having ‘serious’ discussions among the instructors. Even the presence of their CEO did not help the situation much.
The one who saved the day was none other than Mr Sik. Unlike the others, he is technically competent and has many interesting experiences to share. He was able to engage our students and they listened to him. No wonder, Mr Chua BK said that our students should not go to CLF if Mr Sik was not available. The students worked on refurbished speakers, they removed all the screws, inspect the inside and put them back. In the lecture, they learnt about 2.1, 5.1 and 7.1 speaker systems and ported-speaker design.
In the afternoon, every student group made a sales and production process presentation. The students were forthcoming and entertaining in their sales pitch. The topic was very appropriate as hand phone was something very close to their hearts and they talked passionately about it. I was looking forward to the explanation of many terms such as Minimo, CESB but was no wiser after all the presentations. It would have been perfect if there was an immediate debrief on their performance. However, the students got distracted when someone mentioned about dinner and shopping. We mentioned this need to close the ‘loop’ to the trainers but were very surprised that it was not taken up.

Portuguese dinner: The dinner was served at the Old Portuguese Settlement facing the Straits of Malacca. It was much better than the dinner we had the day before but there was no signature dish to distinguish it from the others. I would have passed it off as another seafood dinner if I had not known better. Dinner rating: 6/10
Later, we shopped at a huge shopping centre at Melaka Raya.

11-9-2009 (Friday)
Like typical ‘camping’ youngsters in a foreign land, our students slept very late with many surviving on 2 to 3 hours of sleep. They became restless and noisy during the morning lecture. The chairs that they were using produced a high pitch noise as they swiveled from side to side. The noise was very irritating particularly for the older folks. Even Mr Sik could not hold their attention. The problem was exacerbated by the large group size and their short attention span.
Mr Sik was very kind; he brought from his home a Hi-Fi that cost a hundred thousand ringgit to let us experience high-end music. We were appreciative of the fact that the system was quite heavy and it took a considerable amount of his time to position his equipment for the optimum effect. The machine could virtually transport you to a live concert just by listening to it.
However, only ten students could squeeze into the demo room at a time, the rest of the students were tasked to write their reviews which they would share after the whole exercise.
We could see that the students were getting very restless.
Auyong pushed Mr Maniam to produce more meaningful activities for our students. A visit to the aerospace factory was arranged in the afternoon, the agreed number kept fluctuating between 50 to 60. We have had to keep playing by the ear. Finally, the factory agreed to take 50 people. For those who were not selected for the aerospace visit, Mr Sik activated a production line (no components were used) for them to see. Due to the economic downturn, there was no order for production and not enough qualified personnel to engage our students.
Dinner was at Ole Sayang. This was by far the best dinner we have had in Malacca. Dinner rating: 8.5 out of 10. We shopped at Jonker Street, a World Heritage site. They have Pasar Malam every Mondays, Wednesdays and Fridays and it was no co-incidence that we were there on Friday, thanks to Auyong.

12-9-2009 (Saturday)
The morning was yet another round of miscommunication: we were expecting coaches to pick us up at 9am but none came. Without the transport, it was difficult to move 121 people from point to point. After much haggering with the coordinators from Cubic, we decided to let the students wandered on their own.
We started checking out of the hotel after lunch and finished the process by 1:50pm. The coaches brought us to CLF for the closing ceremony. We conducted the feedback session there and it was followed by the closing speeches by the various representatives. After picture taking at the main gate, we headed home and reached NP at about 8:15pm.

Netriders Competition preparations tips I

This is for the Netriders Contestants only:
As the competition is a team event, the whole team works on the same set of questions. I suggest you appoint among yourself a leader and let me know who is the leader of each team. Then the leader assigns someone to focus on router (CCNA2), another on switch (CCNA3) and the last on WAN (CCNA4).
The competition is a divided into theory and practical which consist of MCQs and Packet Tracer respectively. For the theory portion (MCQ), you can only go forward, there is no going back to change your previous answers. This is very similar to the actual CCNA certification exam.
You will enter your answers into a e-Learning called Moodle. We will create accounts for you at a later date.

Painted Skin

In the movie, Painted Skin, a lady ghost catcher had a precious sword that could only be unshielded from its scabbard by the right person. Nobody could do it. Not her or her grandfather. Not by strength alone. It piqued our curiosity: Why? Who could do it? What power does it have? An aka King Arthur.
When the answer was revealed, I was all ears. I liked its explanation: the sword could only be unshielded by love not hatred. In a desperate act to save her love, the ghost catcher was able to remove the sword and used its effects. The sword even loses its power when wielded by another person.
Painted Skin was adapted from the original Chinese Ghost Stories (聊斋志异). The author, Pu Song Ling, was way ahead of his time.

One particular lunch I had in Australia

While watching the 44th National Day Parade, I was reminded of a lunch I have had with a Caucasian in Australia. I worked for a short period of time in Sydney in 1995. One day, I was having lunch at a cafe and a total stranger came in and sat opposite me. We started talking, after he realized that I was from Singapore. He started to berate Singapore for all the stereotype that the Western media wanted their readers to believe – no freedom of speech, no chewing gum, no smoking, no picking of flowers, no littering; he went on and on.
At the end of his ranting, I told him that as a child, I stayed in a 1-room flat with four other siblings, my parents did not have much expectations of us. In 1995, I owned and stayed in a executive apartment, drove my own car, a graduate and a decent job. I attributed the transformation for the better to our government and I have great respect for them. I gave him some examples to show that the Singapore government has foresight. After I finished, he did not utter a single word.

Iron Man

We watched Iron Man yesterday and left feeling good about it. I was expecting a WWII type of setting given that I knew about it when I was a child. It was a pleasant surprise to find that the story was transplanted into our modern day world which would relate better to the younger generation.
The protagonist’s change in attitude was told in a convincing manner. He started off as a cocky and over-confident man who believed that ‘there is peace as long as he has the bigger stick’ to the realization that his weapons were killing those he sought to protect.
His ability to escape was due to his engineering skills – it gave a feel-good effect and it certainly resonance with the engineers out there.
As he was perfecting his suit; it gave the impression that he was on his way to invincibility. I was beginning to wonder what surprise they could churn out to make us want to root for him. The story could well degenerate to what happened in X-Men evolution: The Origin of Wolverine. I remembered my son’s comment on the latest X-Men installment:
“How exciting it is to see an indestructible man grunting his way around?”
Iron Man outdid itself when it came up with a more powerful enemy in the form of his business partner who stole his technology and he had to fight with a his old and depleted power pack.

Ip Man

After watching the movie, Ip Man, I said, “I enjoyed the movie.”
My eldest son retorted, “But there is no quotable quote.”
I replied, “Well, I liked it when he said, ‘There is no such thing as being afraid of one’s wife, only RESPECT.’”
The next day, I suddenly recalled a funny exercise (a physical exercise for the physically challenged) my wife taught us. It so happened that this son was just beside me. I asked him to do the exercise. He promptly followed my instructions which was quite unusual given his character. It was so funny to see a lanky fellow like him doing that exercise but I had had to put up a straight face.
At the fourteen count (my wife said that the exercise is to be repeated fourteen times), my son sprang up to me, our faces almost touching each other and said cheekily, “There is no such thing as being afraid of my father, only RESPECT.”
Both of us broke into spontaneous laughter.

Keeping Toman as pets

About two months ago, my son was drying his school shoes on the window sill and one of the shoes dropped into my fiber glass ‘pond’. The freak accident decimated my ‘colony’ of shrimps and with it my pride and joy. The last time something like that happened was many years ago when my wife’s orchid dropped into the same pond. The pesticide in the pot of orchid killed almost everything in the pond, notably my daughter’s school of guppies.
A perpetual optimist that I am, I see it as an opportunity to start something new, something different. I decided to keep snakehead fish or Toman. They are well known for being hardy. I have always enjoyed watching a particular Toman in NP pond (outside NP Convention Centre). Every time, I pass by the garden, I would detour and try to look for it.
My good friend, Quek SK, bought me three snakehead and they have been with me for one week already. I am very happy with them for they are such active swimmers bring much life to my pond. I have no qualm about eating them when they are bigger but my family protests to no ends.

Comment from Quek SK:
In America Toman is a pest not pet.
You have foresight. Spore is trying to reduce food imports thru fish farming.
If every household do what you do Spore can be self sufficient in food.
This morning I saw a toman at BT hawker aquarium fish shop.
About 2.5 inch.
Best Regards, qsk

Update:
My wife booted the snake-head fishes out of the house after they gave my children nightmares. The Tomans swam in the middle section of the water. They were not interested in surface food like flaks or worms at the bottom of the pond. The only food they went for were other fishes. The way they attacked other fishes was so vicious that it upset my wife and that sealed their fate as well.
There goes my Toman dinner.

Project Nutz 2009 (24 July)

Click here for more photos.
By now, you would have probably heard that we were beaten to second place in the Project Nutz 2009. Even so, we can hold our head high. Four out of the seven original first team runners could not make it this year for one reason or another.
We refused to be brow beaten. We kept faith in our division. We dug deeper to unearth the hidden gems. With efforts from different quarters, we managed to gather not one but two teams to compete in the race. The made shift team of Chew Jing Yuan, Ong Teck Soon, Ong Meng Tiong, Lim Hock Chuan, Low Chee Kin, Tan Wei Lian and Ng Kee Wan (in running order) ran their hearts and lungs out and better last year record with a timing of 39’ 12”.
Team 1 was built on the foundation of the second team which played a very important role of providing a safety net. We are also very happy to note that an ECE student team led by Chun Yang, ex-President of ECE Society, came in seventh while Cai Yin from AE came in fourth with the Dragon Boaters in their respective categories.
Special thanks to Dr Lim, Nancy, Peng Guan and Kok Fai for coming down to support us. Last but not least, the members of the team 2: Yang Chee Yun, Hang Kim Yam, Hee Juay Jiunn, Teo Tat Lee, Chia Yong Poo, Goh Lay Kuan and Ng Beng Kiat.

Game and Simulation for Learning

Yesterday evening, my wife and I attended a talk on “Game and Simulation for Learning” at the Singapore Science Centre. We were very impressed with a Lego game called “Replica” which went something like this: teams were to make replicas of a model using Lego Bricks. The fastest and most accurate replica wins.
Each team was made up of a builder, 2 architects and an observer. The architects will have their hands behind their back throughout the game and gave verbal instructions to the builder. Only the architects were allowed to see the model which was hidden in a box and then ran to the builder to give him the instructions to build. They can run to and fro the model as often as they want.
On our way home, we thought it would be a good idea to try it on our children. We had a good laugh over what might happen: our youngest boy, WK, would end up as the builder. The brother would give instructions at motor speed, frustrating both of them in the process. The girl would have tripped over herself trying to communicate 3-D ideas and they would end up screaming and crying over it.
Today, after lunch, we got them to do play the game anyway. As expected, WK was nominated as the builder. Being a systematic fellow, he started to arrange his pieces according to shapes and sizes while the other two discussed on the strategy. They played the game with a lot of fun and laughter. No drama, nothing like what we had imagined. They certainly deserved more credit that we had given them.
We all had a good laugh when we discovered that the replica’s color was the mirror image of the original. I supposed it has to do with how we communicate. While it is good manner to talk face to face, it adds to the confusion of whose perspective you are talking about, that is, my left or your left. I think it might be better if the architect goes behind the builder and gives the instructions from there.
Learning Point: Different people use different ways to describe the same thing, for example, imagine a circle and below it is a triangle. Both shapes are about the same size and the circle is just touching the apex of the triangle. Some people will say the triangle is in front of the circle while others will say that it is to the south of the circle.
The meaning of our communication is the response that we get. If someone is agitated at what you said, it is not her fault; it is what you said that made her so.

Pick your own durians

Click here for more pictures.
I have had 3 days of wind in my face and sun on my back in Pulau Ubin (Granite Island). My family stayed from 15-17 June ’09, in Ubin Lodge, currently the only public chalet on the island. We spent our time cycling, fishing, visiting NPark gardens and durian hunting/eating.
Let me share with you a little secret: here is where you find the cheapest local durian in Singapore. To top it all, the durians are fully organic – no pesticide and no synthetic fertilizer.
If you are adventurous, you can even pick your own durians. The best times for the pickings are during the early mornings and 5-6pm in the evenings.
By the way, wild boars love durians too. After their feastings, all you find are empty durian empty shells laid out neatly under the trees. They eat the flesh and seeds whole.
Durian picking, like fishing, is best to learn from an old hand. I learnt from Uncle William, the caretaker of Ubin Lodge, that the stub of the fruit should be just one section if it had dropped naturally and not prematurely because of strong wind or other factors. The fruit should also have a fragrant smell otherwise it is not ripe. The rambutans are ripening very soon, I could hear them calling me.

Man of Little Faith

My family would jog or skate along the Sunset Canal during the evenings as part of the family ritual. As the children prefer to skate, they would finish their rounds much faster and go home on their own leaving behind the two old folks.
Today was no different except that it started to drizzle when my wife and I started to make our way home. My wife turned to me and said, “Do you think the children will bring us umbrella?”
I said without hesitation, “Dan gu gu.” (wait long long in Hokkien)
Just when it was about to pour, we saw a lanky figure running towards us with two umbrellas. Our son came to save us from being drenched. I felt ashamed that I have so little faith in my children.

The power of rubber band

A friend of mine shared with me this little trick: Tie a rubber band around a cup and ants will not climb up the cup anymore! According to him, it works like magic. He had seen ants circling his 'banded' cup and none would climb up. I wonder why?
Do you have any such tricks to share, especially against cockroaches and lizards?

Visitation with a difference

Click here for more pictures.
Yesterday, I had steam boat with some of my NSS students at a coffee shop opposite Shaw Tower. The food was good but the company was better. I thank QiFeng for organizing it. Among the students, I got to meet were four students who are currently on Industrial Internship and under my charge; something I failed to pull off myself as they are frequently required at the customer’s sites.
I lost my hand phone the day before at the NP Convention Centre and I was pleasantly surprised by the support and advices from them. The phone was a very old model and I was quite confident that it would be returned to me soon. But apparently, it was not to be as it was switched off ever since I noticed that it was lost.
My responses to their feedback on my module:
1. I will push for TeraTerm more aggressively from now on for it supports Secure Shell (SSH), a common industry practice. Previously, I let the students choose between TeraTerm and HyperTerminal for they serve our purpose equally well. However, the industry wants SSH and HyperTerminal falls short in this aspect.
2. IOS upgrade is a common task in the industry. While our students knew about TFTP, they did not link the two tasks together. I will put a note in the VCN lab and use Packet Tracer for simulation practice.
3. It is heartening to hear from the students that the exposure to VoIP help them in their confidence. They may not know what to do exactly but they have a toe hold on the problem on hand.
Everyone at the table was inspired by Jackson’s feat – he obtained five professional certifications during his internship. I wish them Godspeed in their quest.
“What is the maximum number of connected switches in the spanning tree protocol?”
“Which has a higher priority: routing or voice packets in QoS?” (routing packets refer to packets sent by routing protocol)
“What is the minimum/maximum load size in an Ethernet frame?”
These are very technical (dry) questions if I were the one asking them. But this time, they were checking each other out. They were all ears. Why? They were sharing questions that their supervisor loved to ask during interviews. This is Learner-centred-Learning (LcL) in truth and in practice.

ECE FOC 1-3 April ’09

Click here for more pictures.
Let me recounted some ups and downs of this camp. Ups and downs, ups come first, so let’s begin with ups. This was the first time we have a real camp fire. The atmosphere was really great when you compared it with a camp fire created by torch lights. The cheers were solid, so solid that I was prepared to receive complaints from the residents. There were variety in the performance and skit. There singing, dancing and acting. This is in contrast to the previous years where students perform mainly hip hop.

As we walked around, it really gratify our hearts to see so many talents among the students:
They showed their enthusiasm and passion in their cheers.
They showed their assertiveness and their creativity when they prepare for the skits.
They showed their endurance and patience when the meals were late.

This was also our first time we used Camp David. We only managed to secure the camp and the trainers quite late. By the time we realized that participants must wear track pants, we have already sent out the welcome letters to the freshmen. We did the next best thing which was to call them up. Unfortunately, the information passed down was also distorted. The message became ‘to bring track pants in case it was cold at night’.

Vulgarity
Throughout the camp, I heard only one expletive and it was uttered when one student mess-up a scene in a skit. The whole camp jeered at the offending student and he apologized promptly. I was very happy with that because it showed that such behavior was not acceptable.

OTOT
We needed to work on the OTOT. I learnt this abbreviation from Wei Hao. It means ‘On Time On Target’. Our timing control was not very good: the camp fire was supposed to start at 9pm but we didn’t get going until 10pm. When Nancy complaint to me about the timing, I told her it was 9 pm, Indonesian time.

Mass Dance
All the campers were invited to perform the mass dance on ECE Induction Day. I looked forward to hearing their cheers again and the Tai Ge Wu (a kind of modern Taiwanese dance). This is once in a life time chance to perform in front of such a large audience of about 700. In all my years in NP, I got to speak to such a large crowd only once when I was the chairman for FOP two years ago. It did not last more than 5 minutes but it was very memorable. I hope the students will feel this way too.

Camp Leadership
I am particularly pleased with the composition of the leadership team which was incredibly diverse and yet able to rally together.

Embedded pipe

As part of my duty, I was given the opportunity to stay at the Loft@94, a student apartment with condominium facilities for 4 days with a few of my colleagues. On the first night, I was kept awoke by an intermittent yet resonating noise. At first, I thought it was a motor cycle at the car park and it would go away soon. But it persisted and persisted. After tossing in the bed for what seems like eternity, I got up and checked with my other roommates.
The reason for the noise was we shared a common wall and the water pipe was embedded in the wall. When he bath, the pipe vibrated and the noise was trapped in my closed room. On top of that, we were on the second storey; the water pressure was maintained by a pump instead of water tank on the top floor. When water flow, the pump was activated causing the noise I thought was from a motorcycle.
I only got to sleep after my colleague finished bathing, which was close to 1 am.

圣经的用词

最近我上了一堂华语课,認识到圣经的用词不是我们一般的用法。我的老师要我们做造句,她写了“能”字。
同学们挣先恐后地说,“能够,能耐,等等”。
我也插嘴说:“大能”。
老师瞪大双眼说:“有这样用法吗?”
我说:“有,神就是大能。

Silly Rhyme

人生本来是 happy
辛辛苦苦去study
不如早点去marry
快点生一个 baby
早上给他吃 roti
晚上给他吃 curry
到了明天就 mati
你说 funny 不 funny
By chance, I again heard the above silly rhyme which was often recited during my primary school days. When I checked with my children, none of them had heard it before so I decided that I must put it down here before it dies with my generation. This is also a good opportunity to practice my han yu pin yin.
BTW, the rhyme must be read in Singlish (exaggerate the first syllabus) to bring out its flavor.

Not so cool

I was reviewing some grad videos. One of them had a student saying, "In XXX, we slept at 1 am in year 1, 2 am in year 2 and 3 am in year 3!" From his expression, you can see that he thinks it is cool to sleep late.
The truth, however, is the opposite: being able to sleep early is a privilege for the smart and the hardworking. All of us should be competing to see who gets to sleep the earliest and yet get the work done.

Life is transient

A colleague wrote this to me. It was so well written that it would be a waste not to share it.

"I visited a friend whose wife is suffering from lung and brain cancer in Tan Tock Seng Hospital a few nights ago. It was a good break from marking exam scripts. My friend and I have DownSyndrome children. When I saw him at the hospital that night, he was looking at his wife who was drugged with morphine, his hand on the bed railing, a total picture of calmness and acceptance.
My wife went and stroked his wife's hair, and speaking words of encouragement to her still body. My friend and I spoke. After an hour, we left.
I can still remember these few words from him: "We were retired for a few years and had plans to stay in Australia for a few months with our son who is graduating from the Uni there. My wife is a very healthy person, waking up at 5am, go for walks. Then this thing happen. Life is very transient."
As we journey on this earth, sometimes we think we are in control of our lives. Most times, we find life is transient and we need friends, our wives and for most of us, we need God. "

Another colleague added the following:
"People feel sad when their loved one is leaving them.
When we eat meat, have we thought of the suffering, pain and fear of the animals caused by our greed?"

Chasing Daylight

I just finished reading a book called 'Chasing Daylight' by Eugene O'Kelly. I would rate it as one of the best books that I have ever read. Before reading it, my preferred way to pass on was to die suddenly while reading, sleeping, jogging or even swimming. Now, I think O’Kelly’s death is even more blessed. His ‘death sentence’ enabled him to have proper closure with first his acquaintance, then colleagues, then friends and finally his family members. He was doubly blessed because he had his wife and children beside him and he did not suffer much pain even right up to his end.
We have lots to learn from him. He took his mentor role very seriously and everyone who read his book became his mentee. He did not give up easily either. The fact that he succeed in entering the alternate state of consciousness despite many failed attempts suggested that he was a very determined man.
I even found an answer to my wife’s complaint when I was courting her. That was 16 long years.

Why I believe?

Recently, a colleague gave me a lift to attend a wake. Coincidentally, the last time, we met outside NP was also at a wake. Invariably, our conversation was centered on health, death and religion. She is a non-believer. While talking to her, I had a deeper understanding of what Jesus said, “It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God” (Matthew 19:24)

I am more used to talking in a position of authority to my children and to my students. But this time, it was the other way round. She is obviously more successful than I am – she drives a Mercedes while I take the public transport. She is more intellectual so much so that I have no answers to many of her questions.

Unfortunately, religion is not science. Many of the things are non-repeatable and hard evidences are lost in the passage of time. To me, the Bible contained so much truth, many of which took me decades to discover their validity that the Bible must be inspired by a higher being as many of the Bible writers were lowly educated people.

When I was younger, I rejected Christianity and resent it because it wanted to control my life, I wanted to be free and be able to do what pleased me. Only when I have my own children, I found myself wanting to control them. Not because I am a control freak but because I love them. Isn’t it ironic?

What we cannot see does not mean that it is not there. I like bringing students to Sabah for YEP. One of the things I would do was to show them Mount Kinabalu in the afternoon. They would not be able to see anything because the mountain would be completely covered by the mist. Some students would even seriously question what I told them. The following morning, I would take them to the same spot. The mountain would be in full view as the mist needed the sun's heat to build up. I enjoyed seeing their expressions of wonderment and disbelief that they could miss something so huge the day before. I believe God is like that, He is there but due to our limitations, we cannot see Him. We cannot rationalise too much in religion. The way to God is through our heart.

Valentine's Day

Today is Valentine’s Day. Let me share with you my first Valentine’s Day in NTU. This happened more than twenty years ago. About a week before Valentine’s Day, our tutorial group rep made a sudden announcement that guys with lady lab partners will buy flowers for their partners in the spirit of Valentine’s Day. I was in EEE where ladies were the minority and in my tutorial group of 15, there were only 3 ladies. I was one of the ‘lucky’ ones.
Everyone knows that my lab partner had a steady boyfriend from Accountancy. He was a six-footer. BTW, the Accountancy Department was moved from NUS to NTU to balance the sex ratio in NTU. But I heard of more success stories of accountancy boys pairing up with engineering girls than the other way round. But that was another story.
I thought my group rep was only joking so I didn’t give much of a thought to it. On Valentine’s Day, I notice that almost every girl was holding a flower. I felt sorry for those without any flowers. In the evening as I was studying in my hostel, I heard knocking sound at the door. Almost the whole tutorial group was giggling outside my room. I was dragged and escorted to my lab partner’s hostel.
I was from Hall 3 and she was at Hall 2. The two Halls were about a kilometer apart. But on that day, it definitely looked much farther than that. What followed were the usual pranks that youngsters played. Many photos (printed ones) were taken. It turned out to be quite an enjoyable experience. How often do you become the centre of attraction? The only another time I felt like that was on my wedding day.

Staff message for ECE Mag 09

My staff message for ECE magazine 2009:
When the wind rises and the waves are high, where will you be? Looking for shelter? No way! We will soar the sky and ride the waves and also extend a helping hand to the less fortunate for we are from Ngee Ann.

We are like the shrimps

Every weekend, I will suck out a pail of water from my aquarium and replenish it with fresh water. Among the aquarium inhabitants are some shrimps, no longer than 1 inch when fully grown. In the process of sucking out the dirty water, I will inevitably suck out some baby shrimps which can be as tiny as 1 mm in length. This follows by the tedious process of catching them back to the aquarium. They cannot be caught with normal fishing net as they are too small. We use plastic cup to scoop them in. But it still strains my eyes and back to get them.
One day, when I was struggling to “save” the baby shrimps, my eldest boy came up to me. Looking over my shoulder, he said, “We are liked the shrimps.”
“Uh? What say you?” I thought. I had wanted to protest but knowing better, I bit my tongue and listened him out. He continued, “There you are, trying to save them but they happily run away. We are also like that, God wants to save us but we choose to run away.”

Classroom

My wife works with children with disabilities. Recently, she attended a seminar which I find worthy of sharing. The facilitator showed a picture with some dots to a participant and asked what it was. After some hesitation, the participant said, “A frog?”
The facilitator moved on to another pupil who did not venture an answer, then the next, also no answer and then the next. When no one wanted to try, he put a small piece of chocolate on the table and declare it as a reward for the right answer.
There were some excitement but it quickly die down. Every time the excitement went down, the facilitator would increase the prize by adding one more sweet. Finally, he offered the entire box. By then, the whole class was filled with people shouting their answers. Mind you, this is a group of highly educated people. The correct answer was eventually given by a young engineer.
What is the lesson? The first person to which the question was directed at, felt a lot of pressure. The take away is to avoid asking difficult question to weak students first otherwise we are setting them up for failure. A sweet or two did not motivate the students. The reward seen through the eyes of the pupils must be proportional to the effort that they have to put in. No matter what the prize is, some people just cannot see it. We need to show them instead of testing them.

School CIP

My eldest son spent the third day of the CNY at a school for the disabled as part of a Community Involvement Program (CIP). He came back very quiet. When he was quiet, the whole house noticed because since young, he was like a broken-down radio – talking non-stop. Since secondary school, he has toned down considerably. But we all felt uneasy when he suddenly became so silent.
I thought I would wait for a little longer to let him internalized his feelings. He had probably seen something we ourselves could not bear to see. When I finally spoke to him in the evening, he said, “Today, we interacted with a group of teenagers who are 2 to 3 years older than we are. But due to their disabilities, they behaved very childishly with behavior one would associate with lower primary students …”
Then he paused for a while and continued, “But from their perspectives, looking at us with ‘perfect’ functioning brains, we were like gods to them!”
I knew why he felt burdened. Spiderman said so, “With greater power, comes greater responsibilities.” Therefore, much is given, much is expected.

#21 Make screencast using Jing capture

MD5 checksum is used mainly to verify the integrity of files in transit. It uniquely identifies a file like its fingerprint. Suppose you downloaded a file and its MD5 signature is also known, you can ensure that the downloaded file has not been tampered with by regenerating its MD5 checksum and compare it with the original known value.
The accompany Jing file shows how to create the checksum using a freeware called FreeCommander.
1. Invoke FreeCommander.
2. Select the target file.
3. File -> Create MD-5 checksum -> Ok

Creative CNY Greeting

牛(扭)来 牛(扭)去,牛(扭)过 去.
I overheard the above greeting on a Taiwanese CNY variety show which featured a creative greeting contest and each contestant was given Ang Pow for his or her effort. This greeting was from a Russian lady dancer/singer. It can be read in two ways: the first interpretation reads 'niu' as ox (the Chinese zodiac for this year) and the challenges ahead that we will overcome. The second reads the 'niu' as twist which is what she does as a professional dancer.
The other contestants were so smitten by her composition that they spontaneously surrendered their Ang Pow to her. The first few probably did it out of impulse while the rest just followed blindly or succumbed to peer pressure.

#23 Course Summary

Summarize your thoughts about this program
I was literally conned into this course: the course brief mentioned Blogging, Technorati, Flickr, Web2.0 Awards, etc and one hour at TLC. To my horror, the one hour was only for the briefing; the course actually stretched for three months. Sounded like Lehman Brothers, isn’t it? My first reaction was I have a certification exam coming up so I won’t have time for the course. My excuse was set aside for I was allowed to start two weeks later than the rest.
To withdraw from the course in NPAL was going to be more painful than the course itself so I decided to make the most out of the situation I got myself into. As an engineer by training, my focus was on application. For every ‘thing’ in the list of 23 things, I was driven by this one question: “How does it apply to me?”
The first thing to hit me was the sense of achievement and ownership– my own website and customized gadgets. From the start, I treated it as a real tool instead of an academic exercise. The mid-course face-to-face session was very helpful for it helped me to solve many problems quickly.
I have always wanted to document the little things that I picked up in life especially my holiday but I never got to doing it. Blogging instilled in me this discipline. For the first time, I did it for the recent December holiday. My father was a computer illiterate and yet through my brother, he could to enjoy my pictures on Flickr. I have quite a few of my relatives and friends who are stationed overseas and they wanted to know how my children are getting on. The blog site served this function neatly.
This course is Learner-centered- Learning (LcL) at its best. The facilitators were always hovering around; we learnt at our own pace and from each other and applied the knowledge almost immediately. I enjoyed the course very much and I have no regrets for the mistake I made when I signed up for the course.

Sting Ray

My two boys bought two small ‘sting rays’ (about 5cm from the mouth to the tail) for three dollars each. From then on, no one dares to put their hands into the aquarium. One day, over lunch, I shared my experience with aquarium hobbyist, Quek SK. He became skeptical when he heard about the price. To him, one just cannot get a sting ray for three dollars whatever the size. He asked for a photo. I was sulking that my friend could think that I cannot even tell whether a fish is a sting ray or not. When I came home and tell my eldest son about it. His reaction surprised me. He smiled and said, “As long as I am happy with them, who care what others think.”
To take a picture of the fish in the fiber glass tank is not going to be a fruitful exercise as the picture will not be clear, so I decided to catch it for photo taking. However, spotting them is already very difficult because there are so many hiding places in the tank. Catching them is close to impossible as they swim very fast and stick to the surface. The only way is probably to empty the tank which I am not keen.
After explaining to my friend about my failure to produce a picture, he searched and found the accompany picture from Internet. That settles the argument once and for all. He was right. The fish belongs to the sucker family and it is known by many names: Borneo Sucker, Borneo Loach, Hong Kong Pleco, Butterfly Loach and Chinese Hillstream Loach.
From this episode, I learned to be happy with what I have and I am thankful to my friend and Internet for the info.

Reminiscing

Recently, I was issued with a new laptop, X200, to replace the aging R40. In the process of backing up my old files, I came across some old pictures which made me regret not blogging earlier in life. The discipline of blogging would have chronicled them in proper order.
Still, I would like to share with you one such photo which I liked very much. It was a picture of my son and daughter – innocent and rebellious at the same time especially the latter. All of us have some rebellious nature in us but adulterated through the years of social conditioning. During the times in England, I enjoyed carrying her around giving the impression (not intentional, though) of a loving father. Actually, she was like a hot water bottle to me in the cold England weather. As I am averse to cold, I needed her more than she needed me.

#20a Report on two RSS feeds

#20a. Report on the latest items in your 2 RSS feeds from before.
From my Google Reader, I realized that Dorene wanted to know the password to the Sandbox exercise. I jumped into her blog and put my two-cent worth.
In another RSS feed, I saw Cheriboy has another Sandbox exercise. That piques my interest.

Children say the darnest things

After a family dinner at NP Alumni, I wanted to show the children the Alumni swimming pool. As we walk past the "Halo Bar", my eldest son looked at the sign and said, "Where angels indulge in sinful pleasure".

This year, we celebrate our birthdays by country. I chose Hong Kong. Being a Cantonese, I have a natural affinity for Hong Kong food and I was all praises at the table. My son just had to rub it in, "Hunger compliments the worst dish". (He was trying to remind me the long wait before we were seated)

On another occasion, we were talking about war and terrorism. The same son suddenly quoted in Latin: "Dulce et decorum est pro patria mori"("It is sweet and proper to die for one's country" in English).

#18 Online Productivity Tools

#18 Take a look at some online productivity tools. Write a blog post on what you have learned.
Online productivity tools such as Google Docs are very powerful concepts. They are free-of-charge and easily to use. There is no need to install or patch the software for they are maintained by the hosting server. They can be access anywhere and by anyone you wish to share it with.
Coupled with netbook* (ultra-lightweight laptop), this is a gleam of the way we work in the future. No more bulky software that take up gigabyte of memory and hours to install and maintain. No more heavy laptop. No more battery guzzling machine.
Netbook* is also known by many names, such as, thin client, ultra-portable, mini-botebook, cloud PC, etc

Milk Fruit

My brother-in-law brought back a basket of fruits on a business trip to Vietnam recently. Among the many types of exotic fruit is one called the “Milk Fruit”. Apparently, it is not cheap, one Sing dollar per fruit. We did not enjoy the fruit until a friend told us that we need to chill it and roll it until they are soft before eating it.

Buah Tarap

I have been to Sabah a couple of times and I recommend you a wild fruit called Buah Tarap. It tastes like Caster Apple but very much less expensive. One big fruit costs only 3 ringgits.
For some reasons, I was not impressed with it when I first tried it. So much so that when my family was in Sabah for holiday, I even told them to give it a miss. A trip in Oct/Nov 2007 changed my perception. The fruit tasted so good that I told myself that I must bring some Tarap back to Singapore to correct my children’s misconception.
The problem was at the airport. The fruit was too pungent to be checked-in or hand carried. In my desperation, I covered 2 Taraps with Avocado and declared them as Avocado. My children wolfed them down and it made all the risk worthwhile.
Sept to Nov is Sabah’s fruit season; you can eat till your heart’s content. But don’t think of durians in Sabah, they are more expensive than what you can get in Singapore and not so good ones too.

#17 Wiki and my students

Create a blog post on how you might use wikis with your students.
I plan to use a Wiki website at wetpaint.com to co-ordinate the ECE FOC '09 for the following purposes:
  1. To facilitate discussions/suggestions.
  2. To make announcements to the group of student leaders and staff committee members.
  3. To share photos.
In addition, I am going to use free Web storage to share some documents such as camper namelist, camp program, budget, recruitment poster, T-shirt design and logistics.

#17 Wiki Sandbox

Add an entry to the Learning 2.0 SandBox wiki.
Honestly, I cannot make the 'head or tail' of the
Learning 2.0 SandBox wiki story which is written by different people at different times. The article looks like the work of a deranged mind. By the way, the Bible was written in similar way except for the lack of technology and over a much greater period of time yet the story is consistent in every way.
I was very tempted to give up on this exercise but I would have missed the point -- the spirit of the Sandbox (scratch pad). It is meant to give us hands-on experience with Wiki, the logic of the story is secondary. The original Sandbox story has many references to cats and dogs, so I continued its tradition. My entry was as follows:
"By now, the cat’s great appetite has caused it to grow to a humongous size. Coupled with its wandering nature, it has triggered a couple of alarms in the neighbourhood. When it strayed into the neighbour’s backyard, its black colour and size give the impression of a BIG wild cat (black panther?) We were told to restraint the cat but anyone who has kept cats before would know that it is close to impossible. You only hear of “walking the dog”, but never the cat. You can confine a dog to a house but not the cat.
One day, ..."
So, you think I make up this story, uh? No, I did not. The accompanying photo shows my son and Ben, the big fat cat (Haslemere, England, 2001)

It is supposed to be a cat and dog story, many thanks to Doris from BA, the other side of the story unfolds, ...
dog decided that chasing cats around the compound and all over the kitchen was really no fun. It just made everyone mad, especially when there were muddy paw prints all over the brand new carpet. One glorious morining, it spied something more interesting in the house just across the road -a new neighbour - an oh-so-lovely maltese of agal. Such luscious eye lashes, such dainty paws and my, my, fur as white as snow. He could feel his heart skip a beat as his thoughts ran wild.Gosh! Was she some kind of a princess? Dog could almost imagine himself fetching a slipper for her to chew on... he wondered how he could catch her attention........ Could this possibly be puppy love????
Doris writes very well and from a perspective uncommon among most people. You can read her blog here.

The story continues ...
Hmm...it'a a tough act to follow. As the dog observed the new kid on the block, a lady in sports attire came out of the house with a cat on a leash, walking towards the tennis court. Whoever has heard of a cat on a leash? The dog was curious and dashed after the lady. Well, all seemed normal as the lady played a few rounds of tennis with her friends while the cat slept comfortably under a shady tree. When they decided that they had enough exercise, the lady just walked the cat home. Now, how did that happen?....No cat fights? Strange....wildrabbit

Wildrabbit is so brave. Knowing that it is a tough act to follow and still do it. We all benefited because of her spirit.

#16 Wikis

Write a blog post on what you have discovered about Wikis.
Wiki is a technology that enables mass collaboration 0n the Web by allowing users to co-edit and create on-line discussions and share photos in an accountable manner. Without Wiki, there will be no Wikipedia. On a smaller scale, Wiki is used to build interest group websites, plan camping trips (e.g. YEP), analyze case studies, write report as equal partners.
After looking up a couple of free Wiki websites, my vote goes to ‘wetpaint.com’. Some Wiki sites are free as long as the number of users are limited (PBWiki’s limit is 3) and others have time limit.

True Wisdom

I join the Chinese church service, not because my Mandarin is any good but somehow when I use English, I connected mostly on the logical plane. I feel more emotionally and spiritually when I use Mandarin.
Recently, I heard a very touching story during one of the services and I would like to share with you. Pastor Zhou was from Shanghai on a mission trip to Northern Thailand. One late evening, a child from a nearby village became seriously ill. His mother, a non-believer, approached the church for help because the church is one of the few in that area that has transport.
However, the journey to the hospital after dusk was too dangerous. It was decided to give the child some fever medicine and they would go to the hospital after the morning prayer.
Pastor Zhou led the morning prayer, in the mid of it, a terrible cry echoed the hall -- the child died in his mother's arms. It was a terrible blow to the mother. The pastor was at a lost too. His years of training deserted him; he could not master the words to comfort the lady.
Near the village where the tribal lady came from was a little rundown church building. The pastor would preach there week after week. The lady would sit quietly on the last row. One day, the pastor suggested to renovate the church building. As usual, there was silence. Then the lady stood up and volunteered to contribute the pillars. Her effort was infectious; others started to come forward too.
As the pastor work with her, he realized that she had accepted Christ as her savior despite the church 'failure' to save her son. That to the pastor is true wisdom.

Hello 2009

With great joy we thank God for the year 2008. This is not only a year of celebrations (Bible Church celebrates its 50th anniversary and NP its 45th) but also a year that spurred us on. At the threshold of a new year, we will be strong and courageous for the Lord goes before us and He will never forsake us.
