Finished Hanoi Tower!!

Just finished my own version of Hanoi tower with C#. Non-recursive, no gray code.
I know this should be a piece of cake for programers, but for me, a beginner, it took me at least 8 hours in total, from asking questions, looking for referance, to plaining , coding and debuging. Boy was it satisfying!

爽～～～

Now, a late night meal to replanish all the glucose I used up in tackling this thing.

Alpha series DSLR, reborn.

Sony
Konica Minolta sold it's camera technologies to Sony last year and backed out of the camera market. Minolta was once a highly recognised brand, but has been suffering for the last few years. At some point, it was bought by Konica, and now it's assets sold to Sony.
(See Konica Minolta's last DSLR here)

Sony has just anounced that the sony branded DSLRs well be marketed under the "" moniker, and the first products, with Minolta's alpha-lens-mount system, will be avaliable this summer. More choices is always better for any market. So it's a good thing that Minolta's ledgend won't be going away. Can't wait to see what Sony will do with DSLRs.

Life science math homework notes

So that whole system of short hands of PDE calculations is called the Einstein notation:
http://en.wikipedia.org/wiki/Einstein_notation

The Levi-Civita symbols, also called permutation or antisymmetric symbols, is actually the εijk part:
εijk
=+1 if (i,j,k)=(1,2,3), (2,3,1)or (3,1,2)
=-1 if (i,j,k)=(3,2,1), (1,3,2)or (2,1,3)
=0 if i=j or j=k or k=i
http://en.wikipedia.org/wiki/Levi-Civita_symbol

While the δij part is the kronecker delta:
δij =1 when i=j
else, δij =0

For (i) in the 2nd question, it wants us to explain the " Euler equation", however, the seems to be tens of hundreds of " Euler equation", and I can't find the right one. Please do tell me if you can.
(∂v/∂t)+ v・∇v = -(1/ρ)∇p - ∇φ

Pandora: Can you help me discover more music that I'll like?

Find Music You'll Love - Pandora

Just found this amazing web jukebox in an article on rohdesign, and it really amazing!

It's a flash based music player. You first enter an artist you'd like to listen, it then starts playing a computer generated playlist with songs of a similar taste, guessing the type of music you'd like. If it picked one you don't like, you could tell it to choose another one, and it'll refine it's guess, to better suit your taste.

The sound quality is quite nice by on-line streaming audio standards. What I like is that it's just like a personal radio station designed just for you, and you could accidentally stumble upon a piece of music that you like but never heard before.

Back to the basics of handhelds

Rohdesign Weblog: Back to the Future: from Zire to Clié
Jim's Tips | PDAs: Back To The Basics
PDA 247 | In Praise of the Z22 by Tom Stoneham

Here's 3 articles on the basics of PDAs: personal information managment. It's intresting that most people don't get it that Palm PDAs are first and fore most electronic organisers.

Yes they can play music, they can surf the net, they can view documents, they may take pictures... you name it. But it's core function is to organise, an evolution of your dayplanner, your pocket notebook. It remembers your appointments, remind you of them; it saves all your contact information, all your notes; it has a list of the things you must do but haven't. PDA stands for "Personal Digital Assistant", it manages your information, your appointments, just as a real assistant should. It s not just a synoym for "flashy toy that does everything". Everyone asks me if it does phone calls, or GPS. What's so important about those two? Isn't your normal phone enough? Don't you know where you are going? Can't you ask your friendly pedestrians for directions?

Yeah, it could play games, it could play videos. But the one single function that make it indispensable is the PIM functionality. It's the important things that count, it's the zen of Palm.

A day of pythons and stupidity

今天中午，大家隨便約耶約，就十幾人一同到一家頗高級的日式料理吃中飯。大三了，還能這麼大一群同學聚在一起，實在不簡單。在去的途中有點感慨，自己跟系上同學越來越疏遠，還在思考原因。不過，一到店裡坐下來，就馬上得到答案了。一瞬間，出現了2大聊天集團；女生談化妝品（我聽不懂）；男生談籃球（無聊，沒興趣）。很好，很好，我的興趣比較特別，都沒有什麼跟大家的共同話題。也難怪我最近越來越常到社辦吃飯，至少，大家的聊天話題不會離我太遠。不過有趣的是，我去人本也不會像跟同學間這麼糟糕啊......

脊椎動物實驗大家玩蛇玩的很嗨。助教帶了他心愛的球蟒和紅紋蚺各一條。球蟒是黑色那條，還有褐色斑點。紅紋蚺則是褐色那條。都很溫和，尤其是球蟒，真的是超可愛的！！而且，摸起來光滑柔軟，非常有質感^^


剛放在脖子上會嚇一跳，真的好冰啊！



晚餐我又來到了社辦

羅得鳥啊～～

天啊，要上腦殘電視台的節目果然要狂耍寶。

在社辦，我忘了是誰拿我的耳機去玩了。後來一回到圖書館，就發現我那不到一年的，Made in China的爛耳機竟然接觸不良，掛了！貪小便宜買sony入門款果然是不對的。不過，也真是的，我這個沒音樂就活不下去的笨蛋，竟因耳機不能用，就心情盪到谷底，今晚也就沒唸到書。唉，雖然現在心情正常了，不過，明天要花800上下去買新耳機了。不過了，on the bright side，至少我不像朋友一樣，只要有「主機板」的東西，管他是桌上型電腦、筆電、手機、PDA全掛。很好，只掛個耳機的我也算是幸運的吧XD

Now, Google's online calendar

Google just came out with a new web app: google calender. Nice and elegant, similar to Gmail. However, I keep everything in my Clie, which is always with no matter if I have a web connection or not. Also, I can't seem to find a simple way to import my datebook data from Palm desktop.
However, what's intresting here is that Calender+Gmail, means an on-line competitor to Outlook. Eat dust, Bill Gates!

Plans for the remaining days of my undergrad life

As I start preparing for tests and prior work for grad school applications, I start to feel that I don't have much time left here.

Here's what I'd wish to achieve in the comming 1.5 years before graduation. This is what I call "reasionable day dreaming" :D

Summer 2006
1. UCLA lab work (Horray! I found it!)
2. Buy camera, ソニー サイバショットH3, H5(more control) or N1(coolness)
3. GRE general test
4. Find graduate school targets

Fall 2006
1. GRE subject test, bio & bio-chem
2. send graduate school applications (a least 15, I guess)
3. 家教打工見つける (saving up for biking trips abroad :) )
4. find next lab for the school year (This time, I 'd like to focus on viruses)

2007
夏と冬はどれ～？
?. 北海道自転車旅行(too cold in winter, but I'm busier in summer...)
?. 蘭嶼自転車旅行(all seasons ok)
(of the above, find at least 3 friends, with a max of 6)

Summer 2007
さよなら　大学生活～～！

社團網頁

在我們車社網頁剛完成時，我自己無聊，去逛了一下其他社團的網頁，很滿足的說：「哈哈，我們車社的網頁果然最棒。」

結果剛剛逛到火車社的2006新版網頁。一開始嚇一跳，「wow，這個比我還猛XD」接著，發現以下幾點：

1. 狂用flash8... 撥接的，等到死吧；PDA/PSP/smartphone使用者，永遠看不到
2. 網頁各部分參雜了各年不同風格的網頁，incoherent
3. 為了美觀，犧牲usability（要連到各頁都要先跳回首頁）
   

以上，犯了我做網頁的3大禁忌，呵呵。

不過呢，優點也不少

1. 好看，高水準
2. 資料豐富（我們的文書呢？）
3. Navigation頗清楚的，不會迷路

希望不久的將來，我會有時間把車社網頁弄的更好。
Major objectives：

1. Elegancy
2. Usability
3. Design consistancy
4. More content
5. The Wow factor
6. Interoperability

1, 2, 3, 5, 6都已初步達成，不過都有改進空間。

北市單車 將登錄車籍

自由電子報-生活新聞-北市單車 將登錄車籍
叫馬英九去死啦
分明就是要找方法以後方便「罰錢」＆增加市政收入

我不爽不是因為我習慣違規，容易被罰錢；而是不爽停車要收錢。莫名其妙。要加裝前燈也很奇怪。1)白天要前燈幹嘛？ 2)安全帽才是最重要的。

還要證照？這又是壓榨市民，增加市政收入的好方法啊！辦證一定又要錢了，以後騎車違規也有「證照」可以看了。

不思考如何鼓勵市民騎車，反而無所不用其極的壓榨環保的單車騎士，這是全世界前所未見的。別以為到處亂貼「單車專用道」的標誌就是有做事。「單車專用道」中，有水潭、有鐵欄杆障礙、有機車、有野狗、有坑洞、有死路，我告訴你，「單車專用道」搞不好比一般馬路還危險。而且還有一大部分是凹凸不平的磚塊地，難道大家都一定要騎雙避陣車？

馬英九下台前，我不期待北市的騎車環境會有任何進步。不過，若有車隊抗議遊行，我一定支持。

很好，這次是前變

剛剛，我的校園車的前變，莫名其妙的撞到曲柄，整個扭曲變形變成一團勾著鏈條，會促進落鍊的廢鐵。

明天去社辦用老虎鉗凹凹看好了。現在2速的前變似乎很稀有，而且只需要再用1年辦的校園車換新的前變似乎有點浪費。另前變勾著鏈條，光要把鏈條從舊前變拿出來就要剪開了；除非新的前變跟Deore一樣有可以打開的螺絲設計，否則可能要打鍊或換鍊......現在，KMC的5速鏈條（我的校園車是前2速後5速的）似乎停產了......囧

我不喜歡必須看人家臉色的事情

以前碰到的事情都是只要自己認真努力，就能夠達成的事。現在，碰到決定權在別人手上的事情，不但很不習慣，沒有踏實感；還因為臉皮太薄，不知在不好意思什麼，就無法權利去做好它。

我不適合搞商業。
昨天去幫Puma store宣傳，光發個傳單，就有「怕會對人家造成困擾」的感覺。結果，發出去的張數比別人少很多。

我也不會搞感情。
臉皮太薄，很怕造成人家困擾，成為「黏人的蒼蠅」。結果所有的表現都很收斂，給人的感覺可能是不夠積極，甚至是「只當朋友」吧。於是，她就被別人搶先追走。而我這個挫折感很重的，就直接把「愛情」這件事拋諸腦後，再也不玩了，放棄了。

現在更是找不到實驗室。
這也要看教授臉色......。丟email都丟得很含蓄，完全表現不出自己有多好。於是，不是被忽略就是被拒絕。

Life is a struggle.

Frantic

In spite the impending midterm exam and reports, I still don't feel like preparing. The search for a summer lab slot has been futile, with no ideas what to do next. As for my GRE, I'm still headlessly memorizing vocabulary, with poor achevement. With summer just around the corner, I'm in somesort of panic, feels kinda like I'm going to screw up my future this year. Don't know how to go on, and I find my self avoiding my problems. I began deleting the unacheveable entries in my todo list, and ignoring others. I am franticly riding my bike as much as I can. I borrowed a book of Edgar Allan Poe's poems, to enchant myself, to feel the helplessness in The Raven.

I now see emptyness and fear in my future; I feel the weight of the world on my back. Don't know what to do.

Quoth the Raven "Nevermore."

再衝巴拉卡

之前有讀者來信，說陽明山的櫻花應該很棒。可惜當時我比較忙，而且想說新中橫已經看了一堆山櫻花，就一直拖延沒去。今天總算是有時間去了。整個下午因研究所考試而放假 ，雖然期中考快了，不過真的念得很煩，就衝陽明山，行義路上，巴拉卡下，再經淡水回來。

今天也順便走了一趟過去一年來一直避開的竹子湖海芋田。一年級班遊時來採海芋，然後它成為我第一次，也是唯一一次送過女生的花（好啦，我知道從植物學的觀點它其實不是真的花啦），象徵當時單純（也有點笨）的情感。後來，每次看到有人手裡拿著海芋，就勾起一些痛苦的回憶。今天能以平常心來逛逛，算是種突破吧！

一直拖延，櫻花果真沒剩多少。上面照片中的不知是什麼花，有點像櫻花，卻是白色的，而且凋謝得差不多了。

巴拉卡的風景還是一樣棒。不過今天風很大，再加上路面品質差，凹凸不平（胎壓不該灌60的，有夠震的），今天下坡很慢。今天的最高速：64km/hr 很神奇的是在下山後的101上的緩下坡達成的，可見巴拉卡的路況有多差。

想說之前都一直帶新生騎，今天來挑戰一下自己，順便練車。上坡時高轉速+有點種的檔位；下坡時也保持定速踩踏，還盡量過彎壓車少減速。不錯，均速有18.4km/hr。不過回程時就腳軟無力了，速度再也無法突破24km/hr。哈哈，體力被我操光了。有點小小不順的是，在台2進士林那又迷路了，一不小心到了社子島，只好折返再接再厲；最後，終於順利回到中山北，回到台北，順道去敗張YUI的新專輯^^

YUI / From me to you

昨天發現YUI的新專輯竟然已經上市一陣子了，我今天馬上把它買回來了^^

去年，YUI的的2張單曲：Tomorrow's way 的MV出現在日本Sony的walkman recommendation site，當時就覺得對於這種乾淨的吉他搖滾音樂有種久違的感覺，就決定等她出專輯一定要買。

整張專輯都是吉他音樂，有點像Michelle Branch的風格，也有點像「光明版」的Avril Lavigne。有趣的是，她很喜歡在歌詞中參雜一些英文，結果，是典型日本人的英文：用的怪怪的，發音也怪怪的XD

我特別喜歡TOKYO這首歌，有種離家流浪去的滄桑。聽著聽著腦中浮現一個街頭藝人抱著吉他到處彈奏，很有感覺。

最後，談談價格。這絕對張值得買的專輯，不過在這個音樂界充滿「貪念」的時代，真的要小心。台北站前商圈（或者該稱為補習街？）的大眾唱片竟賣398！400元一張CD未免誇張了。想必同公司卻沒有競爭者的公館玫瑰或大眾一定賣更貴，也許430左右吧，我猜。Anyway，附近沒有競爭者的唱片行絕對不要進去。我今天就直接殺補習接的大眾/玫瑰，不過發現他們在坑人，就到隔壁的光南，348到手，現省50！

YUI的首頁提供所有曲目的試聽喔

Writing tools

Most people use ball point pens, I can not fathom why. To me the mechanical pencil seems to be the best thing for writing. Using good leads, you get a smooth and clean writing experience. With a small eraser, rectifications are simple and easy. Get a mechanical pencil with a big chamber, fill it up with a whole pack of leads (about 20~40), and you can write on for more then half a year with no hassles.

Let's see how pens do. For corrections, you either need a bottle of slow-drying liquid paper(which sometimes clog up); bulky and expensive correction tape; or scraps of paper and glue. Sometimes the pen is old, or you forgot to recap,or you might have accidentaly dropped it, or for no apparent reason, the ink just gets clogged, or ink gratuitously comes gushing out, or maybe the "ball" of the point just fells out. Farthermore, you use up ink fast, either you buy a new one, or get ink refills, every few weeks. Just think of all the hassle.

Clearly, the pencil is much better. All you have to do is concentrate on your writing.

------

Let's now talk about pen compuuting. Using handhelds for years now, I'm really wondering why we are stuck with keyboards and mouses on PCs. Sure, typing on keyboards is still the fastest input method. But the mouse? You've got to move the cursor to the correct spot, point it and click. that's at least 2 gestures. With a touch screen, all you do is tap, 1 gesture max. Neat and simple. So why didn't touch screens catch on? Price? That is one, but I guess the main reason is that no big company has strongly promoted it on desktops. Microsoft is trying to push it with tablet PC, but with a price way too exorbitant. They threw in a poor writing recognition system, stripped out the keyboard, and told you that you could doodle and scrible. The best combination should really be a touch screen usable with your finger(you could only use the stylus on tablet PCs) to replace the mouse, a good writing recognition system (such as Graffiti on Palms), and retain the keyboard. Wish future desktops are going this way.

------

So, here's the most used writing tools I use everyday:
-a mechanical pencil
-a stylus
