开学没几天，在多方因素的影响下，还是决定重装电脑，从WIN7重新装回ubuntu，但之后一件小杯具的事情发生了---无法连网，使用命令ifconfig查询之后发现MAC地址不一样了。因为之前IP是在WIN7下申请的，又是绑定MAC地址的，所以自然连不上网络。怎么办呢？这时我才发现我的无知。我是这样认为的：MAC地址应该不会改变的呀，为什么不一样了呢？（说实话到现在我还是不明白为什么看到的M]]>https://blog.youkuaiyun.com/youngster21/article/details/5834597https://blog.youkuaiyun.com/youngster21/article/details/5834597youngster21Tue, 24 Aug 2010 14:02:00 +0800转自阮一峰博客：http://www.ruanyifeng.com/blog/2010/08/cable_world_map.html

海底光缆是国际互联网的骨架。光缆的多少，代表一国与互联网的联系是否紧密。
有人利用微软的Bing地图，以及wikipedia的数据，做出了一幅互动式的世界海底光缆分布图 。真是厉害啊。

我见过的这类地图中，它是最好用的一个。
从地图上可以看到，]]>https://blog.youkuaiyun.com/youngster21/article/details/5787608https://blog.youkuaiyun.com/youngster21/article/details/5787608youngster21Wed, 04 Aug 2010 11:42:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5782914https://blog.youkuaiyun.com/youngster21/article/details/5782914youngster21Mon, 02 Aug 2010 15:56:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5782552https://blog.youkuaiyun.com/youngster21/article/details/5782552youngster21Mon, 02 Aug 2010 13:36:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5781765https://blog.youkuaiyun.com/youngster21/article/details/5781765youngster21Mon, 02 Aug 2010 01:06:00 +0800转自：http://blog.youkuaiyun.com/jkdirac/archive/2010/03/13/5372363.aspx

计算机科学是一门包含各种各样与计算和信息处理相关主题的系统学科，从抽象的算法分析、形式化语法等等，到更具体的主题如编程语言、程序设计、软件 和硬件等。作为一门学科，它与数学、计算机程序设计、软件工程和计算机工程有显著的不同，却通常被混淆，尽管这些学科]]>https://blog.youkuaiyun.com/youngster21/article/details/5781759https://blog.youkuaiyun.com/youngster21/article/details/5781759youngster21Mon, 02 Aug 2010 00:50:00 +0800转自：http://news.youkuaiyun.com/a/20100308/217334.html


今天的计算机界是男性主导的领域。据美国的研究数据，计算机专业人员中女性的比例1990年是35.2%，到2000年已经下降到了28.4%。而 攻读计算机本科课程的女性，从1980年代中期的近40%（很高啊），下降到了最近的不足20%。为了缓解这种趋势，欧美各国已经有不少组织在致力于吸引 女性重归计算机科学。
然而，大家可能不太知道的是，计算机的早期，尤其是编]]>https://blog.youkuaiyun.com/youngster21/article/details/5781744https://blog.youkuaiyun.com/youngster21/article/details/5781744youngster21Mon, 02 Aug 2010 00:37:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5767670https://blog.youkuaiyun.com/youngster21/article/details/5767670youngster21Tue, 27 Jul 2010 00:09:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5765264https://blog.youkuaiyun.com/youngster21/article/details/5765264youngster21Sun, 25 Jul 2010 23:12:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5762152https://blog.youkuaiyun.com/youngster21/article/details/5762152youngster21Sun, 25 Jul 2010 00:12:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5758982https://blog.youkuaiyun.com/youngster21/article/details/5758982youngster21Fri, 23 Jul 2010 23:05:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5756719https://blog.youkuaiyun.com/youngster21/article/details/5756719youngster21Fri, 23 Jul 2010 00:15:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5754051https://blog.youkuaiyun.com/youngster21/article/details/5754051youngster21Thu, 22 Jul 2010 00:01:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5753065https://blog.youkuaiyun.com/youngster21/article/details/5753065youngster21Wed, 21 Jul 2010 16:40:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5751117https://blog.youkuaiyun.com/youngster21/article/details/5751117youngster21Tue, 20 Jul 2010 23:40:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5747976https://blog.youkuaiyun.com/youngster21/article/details/5747976youngster21Mon, 19 Jul 2010 23:57:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5747915https://blog.youkuaiyun.com/youngster21/article/details/5747915youngster21Mon, 19 Jul 2010 23:30:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5746283https://blog.youkuaiyun.com/youngster21/article/details/5746283youngster21Mon, 19 Jul 2010 14:20:00 +0800https://blog.youkuaiyun.com/youngster21/article/details/5745059https://blog.youkuaiyun.com/youngster21/article/details/5745059youngster21Sun, 18 Jul 2010 23:26:00 +0800
