$28 Bowl of Beef Noodles

Beef Noodles are must-eat when you visit Taipei. In those poor old days, these were special treats for occasions. As the society got more affluent, chefs started to innovate. Since everyone love beef noodles, at the level of burgers in the US, a sub-culture flourished. Now, it is an obsession for Taipei citizens.

Master Hong’s “#1 in the world” (洪師父 維吾獨尊) beef noodles is probably the epitome of such obsession. Yep, it costs 888 in local currency (about US$28). If you wish, they will give you extra noodles for free. A bowl is recommended for two, three of us shared that and we were all quite full after.

Guess the overall impression was “under-whelmed”. It was an excellent bowl of beef noodles, but way over-hyped. The soup base was rich and seasoned perfectly. The beef, all 4 kinds, were cooked to the melting point (allegedly over 48 hours of slow cooking). The best part is the noodles. They were freshly hand-made and cooked with just the right amount of al dente and substance that was so satisfying. I will be coming back just for the noodles.

I also visited Shi’s beef noodles (史記) during the same trip. Interestingly they have a completely different style of beef noodles. The beef was essentially corned beef briskets and the soup base clear as broth. The noodles were thin with nearly no yield. It was also wonderfully delicious to the point of addictive. There are probably hundreds of beef noodle restaurants in this city and everyone of them is trying to be unique. Taipei citizens are more than happy to sample as many of them as possible and spread the words around.

Sigh… I gained weight whenever I visited Taipei.

Moral Animal

How did we evolve to have values? Are they the derivative of emotions such as love, disgust, anger, sympathy, etc.? If so, why did we evolve to have those emotions? If we did, would other animals also? At the end of the day, where do “moral” come from? If it is genetic, would other animals also evolve to develop the same? Have they?

Almost as a sequel to The Selfish Gene, this book explained that human evolution has not been the subject of natural forces: such as climate changes, food sources, predators, etc. Instead, we evolved by our social behavior among ourselves.

We first evolved by mating choices. In addition to the obvious physical attributes, male needed to make sure the kids were indeed his genetic offspring. This evolved to all those behavior against cuckoldry. Female needs the protection and provision during the kid rearing years. That evolved to select male who loved kids and have strong “family values.” We evolved to love our mates, since those who don’t got bred out eons ago.

Since then, we developed altruism since the sacrifice of an individual help the survival of the community that share some genes. Jared Diamond’s book also explained a similar evolutional force to respect and protect the elder, who are no longer propagating genes. Faced with the disasters that happened at the frequency longer than a life-span, only the old remember how to survive and can save the whole tribe.

For agricultural cultures, such like Chinese, the filial obedience is the key for survival, since land other and critical resources are passed down only to those who do and others got bred out, at least became minority.

At the end, we are simply the vehicle to propagate our genes. But genes are organic and will perish with us. So all we are carrying forward is the encoding information within the genes. Isn’t this deep? We exist to preserve data, really only about 3GByte’s worth.

Imagine that, millions of years of evolution, all for the preservation of information that can easily carried in a small thumb drive.

A Fable

You lived in a upper-middle class neighborhood and Bob, the neighbor, was living well: kids well provided for, unstressful job, eat out and vacation regularly, good clothes, new cars, manicured yards, well cleaned house, nice pets. Not that you didn’t live as well, but they seemed to be just a quarter notch better.

All on borrowed money.

You knew that because you lent Bob money several times. He owed you about a month’s of your pay. You knew that Bob also borrowed from pretty much everyone in the neighborhood. You shook your heads every time they went out for a nice family dinner, worrying on your loan in the back of your mind.

One night, Bob came to borrow money again. He was flat broke and must declare bankruptcy in a week and possibly move out, since he had been delinquent on rents too. He asked for about twice the amount he owed you just to “get over this hump.” “How are you going to pay me back?” “I will try to make more money.” “Are you going to eat out less?” “Absolutely not! My family did no wrong. They should not suffer from this.”

“Wait!” Bob suddenly proclaimed. “I have a collection of precious coins. I will pay you back with them.”

“Really?” (How long have you had those coins?) “How much are they worth?”

“I don’t really know,” Bob said. “I have this old mint in the basement. I can make as many as I need.”

“Are they made of gold, silver, or copper?” You grew a bit suspicious.

“Oh, that does not matter. Right?” Said Bob. “They are rare coins. I am the only one who makes them. I can name my price. For now, I will sell them to you at $1 a piece.”

“Bob, what you are saying is that whenever you need more money, you will just mint more coins and exchange them for dollars.”

“Yep. Brilliant of me!” Bob was all smiling. “In fact, I will pay you back all my debts tomorrow in coins. How stupid of me to have forgotten the mint in the basement.”

Next day, you found a bag of clay coins with a note from Bob that he considered all debts paid. That night, Bob drove away in his nice car, loaded with bags of coins, for a nice celebratory dinner in town. Clearly, all his financial problems were gone.

You remembered that you also lent Steve, another neighbor, some money.

當然是全三部: 射鵰,神鵰俠侶,倚天屠龍記.

上次讀金庸,有數十年了. 當年,好得武俠是在報紙上連載的.作家的習慣是一次寫一周. 其他武俠,也都是論字記酬. 因此寫越長稿費越多. 當年看得過癮.今天讀來, 自然感覺故事的拖延.

當年看的是武功. 現在人物和情節反而是重點了. 金庸能在當年寫人物,今天尤感清新,個個性格鮮明,躍躍欲生,活在腦裏. 以前遇到歷史詩詞都跳過,現在心靜了點,能欣賞多些了. 當年讀小龍女,日思夜想,恨不得飛到書裏見她一面. 今天反覺得郭襄寫的最好.

從小說的角度,人物的重點是他們的缺陷. 情節的重點是不落成套. 射鵰的郭靖黃蓉,神鵰的楊過小龍女,都有他們的性格缺陷,讀者能有共鳴. 倚天的張無忌,唯一的問題就是對”好看女人”抵擋不住. 殷素素死前說的,其實就是重點. 這個”共鳴點”不夠深. 趙敏,及其她女角,也描畫粗淺. 好在倚天情節寫得最好,全書還是好看.

Musician and Butcher

He loves music since childhood. He went through vigorous trainings and entered a renowned music academia. Upon graduation, as life had it, he became a butcher. Decades ensued.

Now he is a middle-aged and successful butcher. He has a happy family, lives in a nice suburb house, enjoys a comfortable middle class lifestyle. There is this regret that he never became a musician.

The local orchestra has a opening for a entry-level violinist, the pay is low, there will be high demand for practice time, his fellow musicians are all decades younger. The manager, his good friend, hinted that if he auditions, the job would be his. Without this favor, however, it is quite questionable.

At this time, his boss, the owner and head butcher, retires. The shop is his if he wants to. More money, better lifestyle.

“Honey,” his wife said. “You are not a musician. You are a butcher.”

We are what we do, not what we want to be. Get over this.

Sixth Extintion

Supposedly, this Earth has witnessed 5 mass extinctions before. Each time, many species simply disappeared, only some of them left fossils for our imagination. Geologically, we are now in Anthropocene epoch. It will end with the sixth mass extinction that will wipe out a large number of species, one of them probably homo sapiens.

So what?

Let’s say Elizabeth Kolbert is right. That Earth is losing biodiversity at an alarming rate. That homo sapiens will be endangered too. even by the most aggressive time table, this will take several hundreds of years, if not thousands. We could survive by learning space migration in time.

Secondly, there is no telling that the extinction of other species will lead to the extinction of this one. Homo sapiens has caused or witnessed the disappearing of many species and we are still here. Why couldn’t we keep going for another 100 thousand years. I will be long dead and also my kids and grand children.

Thirdly, even if I am altruistic and will worry for the grand-children of my grand-children, is there anything that I can really do? If I put myself in a biosphere and never come out, would that have any real impact? If not, what’s the point? Yes, I get the “everyone does their part” idea. But the prospect is so grim that even Elizabeth Kolbert is not offering a solution.

Lastly, at the end of the day, species are selfish. We homo sapiens did not destroy others just for fun. However inefficient we used the resources, we usually have a survival or economical reason doing so. Every wasted drop of water had a purpose. Would we waste that drop if we knew that a species of frog will go extinct? Sadly, for certain purposes, the answer will be yes, even for the most extreme environmentalists.

Sea of iPads

I was expecting the standard and boring rows-of-seats at the gate for my flight. Instead, this Minneapolis-St. Paul gate area is a news stand, bar, fast-food, and a Internet café all rolled into one. Seriously, there are hundreds of iPads ready for the convenience of us travellers.

Basically, it is a order-it-yourself restaurant setup. Each iPad presents the menu, you peruse and click away at your own casual pace: drinks, foods, snack, etc. When you are done, swipe the credit card, and your order will arrive in several minutes. Otherwise, you escape into a general browsing app and just surf the (restricted) net free of charge.

I was flabbergasted on the density of all those iPads. There are several hundreds of them packed into this probably 2000 ft² of space, all of them connected to the net wirelessly. This seems to be the trend these days: super-density deployment.

A typical access point can handle up to 30 connections. Beyond that, devices start to compete for the airwaves and connectivity becomes unstable. An AP could cover roughly 100 ft. radius space. What if there are more than that many devices in that space?

Since APs operate on the same radio frequencies, their signals interfere each other and reduce the transmission efficiency. If there are more than one APs in the same general area, it is best to reduce their power to minimalize their overlapping areas. As people carrying more devices, the coverage radius of APs become smaller. These days, we see APs covering as small as 10 ft radius.

The sea of iPads at this MSP airport is fueling the explosive growth of this industry. It should not be a surprise to see “pure play” companies get snatched away by the giants. Exciting time ahead!

Paper Money

This is my second Ken Follett (after Hammer of Eden) and I am adding his other books to my queue. He published this book in 1977. The version I read included a new preface that was quite entertaining to read as well.

Like the popular TV series “24”, the book narrated the events of a day sequentially. It began as the newspaper editor thought it as a “slow news day” and struggled to fill the pages with interesting stories. Unbeknown to him, two criminals, Tony Cox and Felix Laski, have planned for some major heists that will upset London’s high political and financial circles. I “witnessed” those crime unfold, “saw” the unexpected situations, and was truly suspended till the very end. In fact, as I finished the last page, I thought, “Really? What happens after?” Guess that’s the sigh of a good story.

This is one of Ken Follett’s earliest works. He published them as Zachary Stone and apologized for the story when republished as Ken Follett. The book was quick paced and emphasized more on the plot than the characters. I guess that’s what he apologized. I can see his point when I tried to compare Hammer of Eden from memory. Ken’s primary skills are clearly in the plot, although the characters did become more vivid 20 years later.

How to do Beta?

To have high enough confidence that the product will be good enough.

When company thinks they are done with the development of a new product, be it a new car, kitchen detergent, lipstick, or a piece of software. They would like to know if this product will really be successful in the market place. They would get a small number of real customers to try it before start selling. That is the famous “beta program.”

It turns out pollsters use the same technique to predict the election results. Surprisingly, a random sample of just a few thousand people can accurately predict the next president. This is a well-studied science, also long practiced.

How high the confidence is enough? There are two popular choices of 95% and 99%. How precise the answer should be? The “interval” is usually 10%. The “answer,” therefore, come in three numbers: for example “we will have 95% confidence that 65% to 75% will find it favorable.”

The real science is in calculating the sample size: how many do you need to poll to arrive at the answer? For that, we can Google “sample size calculator.” All of them ask you the size of the actual population, the confidence you wish and the interval that you can tolerate. With that, out spit a number: the required sample size. If you are too lazy to search, 400 is not a bad “go to number.” If you push it, 250 will work too.

Recently, we released a product with a beta program of less than 30 participants. At the end of the program, all of them were satisfied with the product and we released it to the general public. It turned out the product has a defect that affects roughly 5% of the customers. As our luck, none of the participants experienced the defect. Had we computed the required sample size, we would have known that 30 will yield such a low confidence level that this beta program is meaningless. It told us the product was good enough and, in fact, wrongly.

Olympic Penisula

Few people realized that Seattle is probably more than 100 miles from the Pacific Ocean. On her west is the magnificent Olympic Mountain that, on clear days, I can see from my balcony. The snow capped shines brightly in the early morning and the sunset paints the western sky brightly with more colors than you thought possible. But, as a 5-year Seattleite, I never went, until this May day.

Why did I wait so long? And I will definitely go again.

Olympic is not a day-trip and a primarily a hiker’s heaven. I looked for more pampered sleeping and eating accommodations than tents. Lake Crescent is closer to Port Angeles, a small port town, and Hurricane Ridge, the must-go attraction for the Olympic National Park. I reserved Lake Quinault Lodge, planning to tour Tacoma on my way there. The idea is to circle the peninsula clock-wise.

LeMay Car Museum, shaped like a cigar-shaped race car in Tacoma, is a 4-story underground museum with hundreds of cars that are arranged in no discernible order. I was mostly drawn to those old and odd ones: Ford Model-T, elegant and impractical coaches, early battery-power ones, etc. It was a nice stroll for a couple of hours, longer if one would linger and study the exhibitions.
Morning view

We arrived Lake Quinault in-time for an easy hour-long hike at the rain forest. To me, who grew up in a sub-tropical island, rain forest is the most common thing: canopy trees, trickling streams, dripping mosses, ferns of all shapes and forms, insects and various life-forms. It was good to work up the appetite for the dinner at the lodge, the Roosevelt Dining Room. Its view was better than foods that were quite decent as well. It was peaceful, relaxing, and beautiful.
Ruby Beach

With a bit early morning lingering at the lake shore, we continued our journey. Ruby Beach’s giant rocks (or small islands) were mesmerizing. I can probably just wandering here for hours watching the waves and birds. Forks is the city for Twilight fans. Lake Crescent is similar to Lake Quinault with probably slightly better facilities. Around mid-afternoon, we arrived the climax of the trip: Hurricane Ridge.
Hurricane Ridge, Visitor Ctr

It was a calm and bright day, no namesake gust insight. We sat at the short stone ledge just to admire the Olympic mountain range and the distant glaciers. It was 45°F and snow were still on the ground, but the calm sun kept only a light jacket on us. We took a short hike to see Port Angeles and Victoria from a distance. It is the peak of one of the mountains, 5240 feet in elevation. The view was expansive and breathtaking. Had I had sufficient time, I would have taken up a longer hike to Hurricane Hill.
Bainbridge Island Ferry

Yep, Olympic Peninsula, I will be back.
