摘要: 這兩天在學習python,主要參考簡明教程http://www.swaroopch.com/byteofpython/ , 入門很不錯,有興趣推薦參考。
在16章中,作者建議讀者寫一個地址簿程序,還記得寫它都是在大一學c語言的年代了,不過下午還是抽出了一點時間來寫這個程序,寫了兩個版本,一個是使用python 字典來存儲名字和地址,另一個版本則使用python的面向對象特性,來鏈式存儲聯系人對象。

摘要: 據說最近psp最近要升值了~無論是因為破解的原因還是什么,但總之估計sony還是很難想到,當然我們也很值得慶幸的是這幫hack的大牛已然將kvm,python stackless等移植到了psp平臺,強大的ppc支持,可足以媲美幾年前的personal computer,這一點毋庸置疑,更不用去與手機平臺相對比了。

目前 ext已經全面升級了主站,而且也release2.1版本,并新增了一些例子。
最近發布的Firefox3 beta 5版本,個人認為還是比較不錯,運行JS的也更快、上網速度也快了很多。
但經原來做的一些js程序測試,ext2.0版本運行在FF3Beta5上還存在一些顯示問題。

摘要: Have you read Jess In Action by Earnest J. Freedman-Hill? It's one of the better books out there on rule engines, though it does require some experience to get the most out of the book.
A variation on the bookstore could be recommendation engine. That would provide an opportunity to use a rule engine for direct matching on category/subcategory and aggregations.

摘要: 實在忍受不了sun的做事風格和它的開發工具了,nb的beta6一踏糊涂一堆bug,唉~想著就想起來sun中國弄個nb插件的比賽不僅過程糟糕,獲獎了居然還不兌現承諾,到現在也杳無音信,估計是證書也不想發了,真是讓大家對它越發感到沒有信心~~~~~~~~~不提這個了,還是講講Europa 和 myeclipse, 最近在寫一個基于規則的引擎,用的Europa 和myeclipse6 感覺非常舒服,myeclipse的功能也大大加強了比如改進了javaEE5 提高了EJB3開發效率可以支持從數據模型到bean的轉換,java的持久化程度及其Spring-JPA的高度集成。開發ajax的朋友可以發現 myeclipse對ajax的開發和測試做的也非常好,尤其是對js的調試。Web開發的另一個特點是支持RAD web。nb原來喊的一項特色是集成了matisse,在myeclipse目前也集成了它而且對于可視化swing開發非常方便,當然你也可以自己按照,不直接更新。
myeclipse中集成的derby和tomcat也大大加速了服務器的連接和部署,調試等。至于db視圖個人使用oracle

摘要: Given a picture composed entirely of horizontal and vertical line segments, calculate the minimum number of times you must lift your pen to trace every line segment in the picture exactly n times.
Each line segment will be of the form "
" (quotes for clarity), representing a segment from (x1,y1) to (x2,y2). Segments may cross each other. Segments may also overlap, in which case you should count the overlapping region as appearing in the drawing only once. For example, say t 閱讀全文

摘要: In most states, gamblers can choose from a wide variety of different lottery games. The rules of a lottery are defined by two integers (choices and blanks) and two boolean variables (sorted and unique). choices represents the highest valid number that you may use on your lottery ticket. (All integers between 1 and choices, inclusive, are valid and can appear on your ticket.) blanks represents the number of spots on your ticket where numbers can be written. 閱讀全文

摘要:
Let's say you have a binary string such as the following:
011100011
One way to encrypt this string is to add to each digit the sum of its adjacent digits. For example, the above string would become:

摘要: People enjoy mazes, but they also get them dirty. Arrows, graffiti, and chewing gum are just a few of the souvenirs people leave on the walls. You, the maze keeper, are assigned to whiten the maze walls. Each face of the wall requires one liter of paint, but you are only required to paint visible faces. You are given a map of the maze, and you must determine the amount of paint needed for the job. 閱讀全文

摘要: In written languages, some symbols may appear more often than others. Expected frequency tables have been defined for many languages. For each symbol in a language, a frequency table will contain its expected percentage in a typical passage written in that language. For example, if the symbol "a" has an expected percentage of 5, then 5% of the letters in a typical passage will be "a". If a passage contains 350 letters, then 'a' has an expected count of 17.5 for that passage (17.5 = 350 * 5%). Pl 閱讀全文
