		<title>Y-combinator in Python</title>
		<description><![CDATA[

In my current work, the main stream platform is .NET.  I have not invested a lot of time to start to program in C# for .NET, but I am kind of attracted by F#, which is a functional language for .NET that I would like to know more about. 
Recently, I purchased a book [...]]]></description>

		<title>phdfs.py, a ctypes wrapper of hadoop libhdfs for python</title>
		<description><![CDATA[

I use python and hadoop distributed file system (HDFS) to process large amount of data at work.  Instead of using the regular map-reduce mechanism provided by hadoop, I have my home-made map-reduce python engine written using Pyro.  It turns out it is quite efficient and sometimes it is much faster than the corresponding [...]]]></description>

My neighbor shows me this article from East Bay Express. Those stories sound very familiar.  My personal feeling is that such academic system should be fixed soon.  The academic society should give more recognition to postdocs.  
As a postdoc, you don&#8217;t get those benefit to students. You are not considered as a [...]]]></description>

		<title>奇文共賞</title>
		<description><![CDATA[

在二十一世紀的今天，台灣的某大報系下的海外版的社論出現下列的句子：

『在「百年老店」裡，58歲的馬英九是春秋鼎盛、如日方中的新星。』
『他領導國民黨仆而復起，號召台灣人民、尤其是青年一代，終結了台獨政權，正是「青年創造時代」的典型。』
『愛因斯坦的「相對論」改造了百年間的科學奧秘，而孔孟之道卻歷經千餘年影響世道人心，連馬克斯信徒也不得不信。』
『鼓勵青年學習馬英九，絕不是搞甚麼「偶像祟拜」，更無意要造一座「新神」，而是就近取譬，用大家都看得見的事實，期勉繼往開來的青年世代，好好鑄造自己、鍛鍊自己，無負「青年創造時代」的期望。』

久居國外，我對馬英九了解不算多，也沒有意見。但看了這文章後，不得不想起那連小學裡作文都要以『解救大陸水深火熱同胞』『以三民主義統一中國』的年代。也許，只是也許，某聖君可以不和獨裁磕頭，完成反共復國的大業。這樣就不用每年去拜拜了。
Disclaimer: 我年幼無知的時候為了考試或是混公假，應該也寫了不少奇聞，不過那可是上世紀的歷史共業呀！

		<title>My one day trip to Lugradio, San Francsico, 2008</title>
		<description><![CDATA[

從 PingYeh 那聽到有 Lugradio 這週末在 San Francisco 舉行, 一時興起,決定和老婆女兒告假一天去看看熱鬧。
雖然我在 1993 還是 1994 安裝過 Linux with kernel version 0.97 後，有幾年是非 Linux 不用的人，參加 Linux / open source 社群的活動倒是第一次。台灣的 open source 活動開始熱絡的時候，我人已不再台灣，而人在米國的時候，因為學業和懶的關係也沒有看看過有沒有甚嘛好玩的活動可以參加。所以對我來說，這一次湊熱鬧的感覺是很新鮮的。

我約十一點多到達會場，當場交了米金大洋十塊錢，註了冊，拿了名牌和有贊助商的小禮品的小袋子就進到會場裡逛逛。會場是在 San Francisco  Metreon 戲院的頂樓的 CITY VIEW，從前到 Metron 時從來沒聽過有這麼個地方可以辦活動又還有不錯的 city view 的地方。同一時間內，會場會有三場演講進行，你可以選擇比較有興趣的來聽。不想聽的話，就可以逛逛廠商地展示。我隨意聽了幾個演講：其中有 Second Life 的人來說他們 open source 的策略，有 Bungee Connect 的人示範他們的發展平台，有 VMWare 的人展示 Virtual Machine 的 [...]]]></description>

I wish I have a little bit more virtual memory so I can convert virtual money to real one.

iPhone is a fancy toy with a lot of power but Apple deliberately locks a lot of the potential power.  One thing I like to do on an iPhone is to be able to read CHM files.  As a weekend project, I setup the tool chain for iPhone following the instructions.  Then, [...]]]></description>

Tomorrow, a new day with new challenges! What a great feeling for entering the next stage of my career! Although I have to make a tough decision, it is indeed time to move on. I am really feeling the excitement of a new environment and a new career path now.

		<title>用 python+OV 寫中文輸入法</title>
		<description><![CDATA[

前一陣子看到 lukhnos 在寫一個能讓 OV 用 Ruby 來寫 filter 的模組，一時心血來潮想看看如何用 python 來寫 OV 的 filter 的模組。花了點時間研究了一下如何在 C/C++ 中內藏 python。 雖說用 python 來寫程式作研究也有好一陣子，也曾經用過 SWIG 來控制用 C/C++ 寫的物理模擬程式， 在 C/C++ 中呼叫 python 倒是第一次實做。花了點時間寫了個 prototype，在 lukhnos 的協助下，搞定了一個讓 OV 可以用 python 寫 filter 的模組 (在 OV 的 svn repository: Modules/OVOFPythonBased/ 中)。
OV 的 filter 主要是呼叫一個叫 process 的 method。傳到 process 中的只是一個字串，所以實做 OV [...]]]></description>

		<title>Circular references in python</title>
		<description><![CDATA[

The following code create circular references in python:

>>> aRef = []
>>> aRef.append(aRef)
>>> print aRef
[[...]]

This creates a list object referred by a variable named &#8220;aRef&#8221;. the first element in the list object is a reference to itself.  In this case, the &#8220;del aRef&#8221;  dereference aRef to the list object. However, the reference count of [...]]]></description>

Quickhull is an algorithm that is similar to the quicksort using a divide and conquer strategy to find the  convex hull for scattered points.  The green line in the plot is the initial base line and gray lines are the intermediate base line.  The final convex hull is shown in red.

I have been a fan of the &#8220;treemap&#8221; algorithm to visualize data with tree-like structure .  Finally, I decide to implement one last Friday noon. After a few hours, I had a basic Treemap class in python.  When I was testing the class, I found the algorithm can generate some interesting artistic painting [...]]]></description>
