Embedded Python + wxPython
跟上一篇依樣，只是這次是用另依種Embedded的方法
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import wx
app = wx.PySimpleApp()
frame = wx.Frame(None, -1, u"你好, 世界")
frame.Show(True)
app.MainLoop()
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import wx
app = wx.PySimpleApp()
frame = wx.Frame(None, -1, u"你好, 世界")
frame.Show(True)
app.MainLoop()

Embedded Python
我是依thinker的文章（Embedded Python 之一）來作學習。
連結：http://heaven.branda.to/~thinker/GinGin_CGI.py/show_id_doc/234
原始的程式碼
#foo.py
def hello(a, b):
return a + b

在mac中，編譯opengl注意事項
發生問題
error: GL/gl.h: No such file or directory
error: GL/glu.h: No such file or directory
解決辦法
將
#include <GL/gl.h>
#include <GL/glu.h>
改成
#include <OpenGL/gl.h>
#include <OpenGL/glu.h>
編譯時注意-lGLU -lGL -framework OpenGL
error: GL/gl.h: No such file or directory
error: GL/glu.h: No such file or directory
解決辦法
將
#include <GL/gl.h>
#include <GL/glu.h>
改成
#include <OpenGL/gl.h>
#include <OpenGL/glu.h>
編譯時注意-lGLU -lGL -framework OpenGL

在mac中，建立應用套件
建立一個叫tool的資料夾。
之後，在tool資料夾裡，建立一個叫Contents的資料夾。
再建立MacOS和Resource二個資料夾。
將執行檔丟入MacOS資料夾。
將圖示丟入 Resource資料夾。再打開Developer->Applicationis->Utlities的Property List Sditor

在mac中，建立應用程式的圖示（icns）
要先安裝xcode(在第二片安裝光碟中)，之後在用Developer->Applicationis->Utlities的Icon Composer編輯圖檔，就可存成icns檔

[轉貼]獨立遊戲開發者的獨孤九訣
以下文章轉貼至猴子靈藥。我個人，覺得翻譯的很用心，所以貼出來和大家分享。
原文出處：Nine Paths To Indie Game Greatness
本文的作者，是一位曾製作過 PC、Console 以及 Mobile 平台遊戲的專業開發者。自從他以《Quake》內附的編輯器，製作出第一個遊戲關卡的那一刻起，他就領略到了創造遊戲的那種無上樂趣，也因此下定決心開始學習如何製作遊戲。然而當他在遊戲業界中，經歷了六年的工作生涯後，反而開始質疑自己是否擁有繼續開發遊戲的渴望。就在他決心離開遊戲業界，去嘗試其他的事物之後，反倒從如新生嫩芽般的獨立遊戲社群中，再次重新找回自己對於創造遊戲的熱情。

關於sun.audio出現Could not create AudioData Object的錯誤
這個問題是在audioStream.getData()中發生的，
102 public AudioData getData() throws IOException {
103 int length = getLength();
104
105 //limit the memory to 1M, so too large au file won't load
106 if (length < 1024*1024) {
107 byte [] buffer = new byte[length];
108 try {
