Cockpit and Computer Dashboard

When I was younger, I was quite amazed by the dense wall of dials and controls in an airplane's cockpit. It was so overwhelmingly complex. I always wonder how is it humanly possible for the pilots to comprehend it all and to control the components of a machinery as complex as this.

Cockpit controls

Now that I work with computer system, I have to look at pages and pages of dashboard to keep tab on many different aspects of the computer systems across a cluster of machines. We also have some of these dashboards showing in a large screen on a wall. Does it reminiscent of the wall of meters on a cockpit?

Computer Dashboard

I think our computer system actually have far more control than a airplane. Each computer have tens to hundreds of tools (like basic Unix tools and other software). Compares to the switch and knobs on an airplane, each computer tools can support a wide array of parameters so that you can do complex things than just turning it on or off. Thinking about it this way, perhaps the cockpit control isn't so complex after all.

Following Borgen

I find TV programms uninteresting. I have more or less stopping watching TV altogether after I grew up. I do not expect to fall for a TV drama After all these years. But the Danish political drama Borgen is exceptional! I am completely hooked after the first episode.

Borgen

Political party leader Birgitte Nyborg has accidentally become Denmark's the first female Prime Minister. It takes an intense wrangling for her to pull the unstable coalition together. In every episode there is a new struggle, new crisis and new personal dilemma. What makes Borgen special is the moral challenge it poses. Those questions linger on my mind long after story ends.

How Not To Play A Game

A few year ago Tatchee started playing Flying Squadron (飛行棋). He liked it so much he grabbed me to play all the time. Each player of the game has four planes. You advance the plane by a number of places determined by rolling a dice. Once a plane fly around the circular course it can land in the player's home base. Whoever landed all the planes wins. You can also shot down your opponent's place when you land on top of it. In that case the shot down plane has to start over from the launching pad.

flying squad

Tatchee was only a few years old then. The funny thing is he did not really grasp the objective of the game. He knew how to roll a dice and to make a move. But he has also invented funny rule like giving away a dice roll of "6" to the opponent, who needed the "6" in order to launch a plane. When you have a long steak without rolling any "6" and all your planes are stuck in the hanger, it is really great that he will give you what you need. Since he was so nice, I have also refrained from shooting down his plane when I have a chance. Somehow we have subverted a game that is competitive in nature and turned it into a cooperative game. He was so innocent then. But it was also refreshing to play the game in such new way.

He has grown up and learned of course. Now he plays to win, just like everybody does. No more giving advantage to the opponent. Why would anyone do that? But the extend he would go to be the winner bugs me. How about playing game because it is fun? Is winning really so important. Sometimes it really bothers me when I see him tried so hard and he also incline to cheating and sabotaging. Sometimes he insist to make invalid moves to advance his position. Other time when he is facing a losing position, he simply swept all the pieces or the board and decided he don't want to play anymore.

Today he has asked me to download a new mobile game. Initially he was enthusiastic about the new game. But after awhile, he couldn't figure out what to do in the game. Soon the 15 minutes time I rationed him has ran out. He erupted into an emotional outburst, calling the game stupid and that it cheated him the 15 minutes of game time. He went on raging for a while and even dropped tears over that.

Games just do not seem to be much fun sometimes.

Algorithm for the Turnpike Reconstruction Problem

I have spend quite some time to come up with an algorithm to the solve Turnpike problem. turnpike algorithm in Julia. A causal look at says the complexity is beyond 2^n. But in practice it compute instanteously for a data set of about 16,000 delta numbers.

Here is the description of them problem. Suppose there is n increasing integers p_1 < p_2 , ... < p_n, we are given the difference of between every pair of points. The Turnpike reconstruction problem is to reconstruct the point set p_i from the distances of the form |x_i − x_j|.

Daddy is a TV Snatcher

The other day I have denied Tatchee TV time. I have been telling him to finish homework the first thing he return home. Instead he was fooling around, touching a bit of homework, having snack, reading comic books. Despite my constant nagging, he wasn't focus on his work. At the end it went pass the deadline I've imposed. So he lost his privilege to watch TV on that day.

TV Snatcher

He reacted strongly to this and basically just blew up. Somehow he felt he is entitled to TV. He haven't thought much about not finished homework on time as I've asked him to do. Perhaps in his mind the only think of I was being unfair to him.

Later that day he drew a picture himself that portrait me as a monster TV snatcher trashing TVs.

I Hate Ikea

Once upon a time, Ikea is my furniture palace. Their design is fresh and chic. Their price is low. The flat packaging is easy to carry home. But as I grow, I find their design does not cut it anymore. The construction is flimsy. The materials are cheap. And the design look fake. Their price is not even that low compare to other furniture with better quality. [more...]

California Beautiful

I was cleaning up my stuff. There is a large stash of maps I have collected. Everytime I went to a park, I picked up its brochure. Over the years, I have visited just about every major parks in the San Francisco Bay Area. There are wonderful mountain vistas, tranquil redwood forests, incredible coastlines in Point Reyes, gorgegous view of Golden Gate Bridge, the urban oasis Golden gate Park. Some of these places are within jogging or biking distance from me. [more...]

New York Loves California

A Moveable Feast

I often heard how productive and how innovative California's agriculture producers are. Perhaps this is best illustrated in National Geographic's story on food import. The picture are fresh produce from four upscale markets in Manhattan. They traveled a long way from where they grown to the New York city. The origin with most varieties? California contributed 21 kinds of food out of the 60. This is more than 3 times the rest of United states. Actually California has produce more varieties than all other major region combined, with 6 from United States, 6 from Mexico, 5 from Italy and 3 from Costa Rica. [more...]

New York U-Lock

I'm shopping for a new bicycle U-lock. If a regular U-lock is not strong enough for you, there is a product line known as the Kryptonite New York U-Lock. These are extra heavy U-Lock made of hardened steel. Presumably people who need extra security would go for this. It also cost about double compare to a regular U-Lock. [more...]
