我自己就是浪费了很多时间的一个人。我不打麻将，我不经常的听戏看电影，几年中难

得一次，我不长时间看电视，通常只看半个小时，我也不串门子闲聊天。有人问我：“那么

你大部分时间都做了些什么呢？”我痛自反省，我发现，除了职务上的必须及人情上所不能

免的活动之外，我的时间大部分都浪费了。我应该集中精力，读我所未读过的书，我应该利

用所有时间，写我所要写的东西，但是我没能这样做。我的好多的时间都糊里糊涂的混过去

了，“少壮不努力，老大徒伤悲。”

然而悔之晚矣。

他曾用歌唱出“天空海阔，要做最坚强的泡沫”，又感叹“可会知我心里困倦满腔”，一边吟唱“我纵要依依带泪归去也愿意”，一边又要让“风继续吹”因“不忍远离”，可最爱的歌总算唱过。只是，“谁能代替你地位”？

 

转眼间，哥哥逝去已经八年，伤痛与愕然也许淡漠，思念却从未停止。每年的9月12和4月1，因为哥哥，成了缅怀与追思的时节。也许，心中有爱，他便似从未离开这个世界。

 

2010年，在CNN的两个评选中，哥哥均榜上有名。一是“史上最伟大的二十五位亚洲演员”，一是“过去五十年闻名全球的五大指标音乐人”，在后一个评选中，哥哥位列第三，与迈克尔·杰克逊，披头士，猫王和鲍勃·马利齐头并肩。——是的，他没有被遗忘，反而愈发闪光。

 

今天，让我们一起，回望大银幕上风华绝代的——张国荣。

 

 

《英雄本色》，1986年。饰演：宋子杰。主题歌《当年情》：拥着你当初温馨再涌现/心里边童年稚气梦未污染/今日我与你又试肩并肩/当年情此刻是添上新鲜 ——在吴宇森这部男儿史诗中，哥哥贡献了在周润发的丰神潇洒、狄龙的稳健悲情之外的疯狂和脆弱，他眼神中的矛盾和迷乱叫人心疼。

 

 

《倩女幽魂》，1987年。饰演：宁采臣（剧照来自2011年修复版）主题歌《倩女幽魂》：人生路美梦似路长/路里风霜风霜扑面干/红尘里美梦有几多方向/找痴痴梦幻中心爱/路随人茫茫——王祖贤与哥哥成就了最完美的、空前绝后的小倩和宁采臣。

 

 

《胭脂扣》，1988年。饰演：十二少——凄艳哀怨，吊诡奇谭。电影里如花赴死，十二少偷生；电影外十二少断魂，如花决然随他。如何不叫人唏嘘。

 

 

《倩女幽魂Ⅱ》，1990年。饰演：宁采臣——梦如路长，快乐少年郎。

 

 

《纵横四海》，1991年。饰演：阿占。主题歌《风继续吹》：风继续吹/不忍远离/心里极渴望希望留下伴着你 ——港版《祖与占》，一代人的经典回忆。只可惜，红豆与钵仔糕尘世徜徉，而斯人已去。

 

 

《阿飞正传》，1991年。饰演：旭仔。主题歌《何去何从》：我的心/是寂寞是孤寂/我的爱/是迷惘无所寄/黑夜中 寻觅一些感动/不知何去何从 ——忘情的独舞，眼角眉梢的幽寂。今夕何夕？故人西去。

 

 

《霸王别姬》，1993年。饰演：程蝶衣——“说好了是一辈子，差一年，差一个月，差一个时辰，都不是一辈子！”十年后，你终于化蝶，一辈子，如此而已。

 

 

《霸王别姬》，1993年。饰演：程蝶衣——“蝶衣，你真是不疯魔不成活啊。”哥哥又何尝不是？

 

 

《白发魔女传》，1993年。饰演：卓一航。主题歌《红颜白发》：若这一生/欠这一晚/谁说爱是这样难/恨爱之间分不散/红颜白发/更觉璀璨 ——自古美人如名将，不许人间见白头。有些事，也许不见得就不是好的。

 

《金枝玉叶》，1994年。饰演：顾家明。主题歌《追》：一追再追/只想追赶生命里一分一秒/原来多么可笑/你是真正目标

 

 

《东邪西毒》，1994年。饰演：欧阳锋（剧照来自2008年修复的《东邪西毒：终极版》） “很多年之后，我有个绰号叫做‘西毒’。其实任何人都可以变得狠毒，只要你尝试过甚么叫‘忌妒’。我不会介意他人怎样看我，我只不过不想别人比我更开心。”——希望你在天国，能比别人更开心。

 

 

《东邪西毒》，1994年。饰演：欧阳锋（剧照来自2008年修复的《东邪西毒：终极版》） “我知道要想不被人拒绝，最好的方法是先拒绝别人。”

 

 

《夜半歌声》，1995年。饰演：宋丹平。主题歌《夜半歌声》：用尽一生/也愿意去等/总会有一天/把心愿完成/带着你飞奔找永恒

 

 

《风月》，1996年。饰演：郁忠良——哥哥与陈凯歌的再度合作，可惜影片未臻完美，亦被掩盖于《霸王别姬》的光芒之后。

 

 

《新上海滩》，1996年。饰演：许文强——哥哥版的许文强更加悲情，更加沧桑，强烈的末世感令人绝望窒息。

 

 

《春光乍泄》，1997年。饰演：何宝荣 ——何宝荣也许是华语同志片中最让人怜惜的角色，他孩子一般任性迷惘，在命运的河流中挣扎沉浮，渴望爱又无力爱。自我放逐，毫无方向。这到底是何宝荣，还是张国荣本人？

 

 

《摄氏零度·春光再现》，1999年。《春光乍泄》的纪录片。

 

 

《恋战冲绳》，2000年。饰演：Jimmy——哥哥后期难得的轻松搞笑片，倘若电影照进现实，该有多好？

 

 

《异度空间》，2003年。饰演：阿占 ——因入戏太深而深陷困扰，也许是造成悲剧的间接原因之一。将自己变成戏中人，是影迷的福气，戏中人上身，却是我们难以痊愈的心头伤口。

 

 

为你只是你那么贪靓，为何不走得漂亮一些？

为你钟情 倾我至诚 请你珍藏 这份情 然后百年 终你一生 用那真心痴爱来做证

小区宽带升级成了光纤，2M变成了10M，爽！不过很吭爹的是，只能连四能PC，再连就不能上外网了，日啊！电信你大爷，你就是李莲英！

人民群众是智慧滴！GOOGLE了一把找到解决办法：

我这有一台Ubuntu的内网服务器，可以通过Squid代理服务器使其它PC上网，

安装：

root@ubuntu:~$ apt-get install squid

root@ubuntu:~$ vim /etc/squid/squid.conf

/INSERT YOUR OWN RULE(S) 找到  大概在671行的样子

INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS

Example rule allowing access from your local networks.

Adapt localnet in the ACL section to list your (internal) IP networks

from where browsing should be allowed

#http_access allow localnet

http_access allow localhost

And finally deny all other access to this proxy

http_access deny all #修改这个地方接受所有IP，当然也可以限定只允许一些IP

http_access allow all

退出保存!

执行:

root@ubuntu:~$ squid -z

root@ubuntu:~$ /etc/init.d/squid reload

root@ubuntu:~$ /etc/init.d/squid restart

root@ubuntu:~$ squid -k parse

按教程来了这几步，好像没有生效，后来重启了一下就可以用了！

在其它PC上就可以设置代理，代理IP是刚刚设置代理服务器的网IP，端口是默认的3128

其它命令：

root@ubuntu:~$ squid (后台启动)

root@ubuntu:~$ squid -k shutdown (关掉代理)

无意间在GOOGLE邮件列表中看到新车间的话题，看到他们的四旋翼项目，很感兴趣，读小学时候曾把家里的电器都拆过，很是喜欢折腾啊，后来大点了要考试，折腾代替不了考试，这个兴趣如此就停了好多年。

Arduino是一个开放的硬件平台，包括一个简单易用的I/O电路板，以及一个基于Eclipse的软件开发环境。Arduino即可以被用来开发能够独立运行，并具备一定互动性的电子作品，也可以被用来开发与PC相连接的外围装置，这些装甚至还能够与运行在PC上的软件（如Flash，Max/Msp，Director，Processing等）进行沟通。

从淘宝上购得一块Arduino MEGA ATmega1280 AVR开发板，198RMB啊，买回来没两天，因为写了一个程序，把控制器芯片固件损坏了，郁闷了几天，没办法只得去买块Arduino USBtinyISP v3.0 专用下载器来刷板，RMB49。

今天订的无刷电机、电调已到货，回家继续折腾…

感慨二下：有淘宝真TM方便！搞硬件很烧钱！

网站用nginx在跑，网站经常疑似被挂掉，只因没钱买了个便宜的VPS，米国滴，经常被重启，为毛？米国也有G党？有木有？有木有？太坑爹了！
