June 30 Gentoo的问题解决之道首先有两点建议：
怎样利用这些途径：
要注意的地方：
我们将来要做的：
June 29 python shutilThis is amazing!!!The tickless kernel feature (CONFIG_NO_HZ) enables 'on-demand' timer
interrupts: if there is no timer to be expired for say 1.5 seconds when
the system goes idle, then the system will stay totally idle for 1.5
seconds. This should bring cooler CPUs and power savings: on our (x86)
testboxes we have measured the effective IRQ rate to go from HZ to 1-2
timer interrupts per second http://kerneltrap.org/node/6750 感悟……Copied from http://mjtsai.com/blog/2002/11/25/perl_vs_python_vs_ruby/ "Specialization is for insects." -Robert A. Heinlein Learn as many languages as you can. The way to improve your programming is not by learning the intracacies of a particular language, but by learning many different paradigms. When I learned Java, my Basic programs became more structured. When I learned Haskell, my Java programs became more interface driven. When I learned Python, all my programs in Java and C# became cleaner (though annoyingly verbose). Perl, Python, and Ruby all have their strengths. If you know them all, you can 1. Decide which language is best for a particular task. June 26 香蕉球原理香蕉球就是小贝的绝活 小学的时候在一个科普报纸上看到过香蕉球原理 今天在水木上看到一帖 算是得到一点印证 和流体力学有关 就是说空气不是超流体 球表面粗糙 旋转时表面空气会随之转动 这样，球在旋转中前进时，旋转方向和前进方向一致的一面，球表面带动的空气的流向和外面空气流向相反，会抵消一部分空气流速，速度变慢，而低速会导致压强增大。另一面是相反的情况，所以压强减小。两个效果叠加在一起，球就会受到法向力，使球的运行轨迹发生弯曲。而且在这个力在一定转速范围之内，与转速成正比。 所以要使球能够在横梁前下坠，发任意球时搓球的方向一定要是斜向上的 Copy 自一个老同学的blog
June 23 捷克从PS2的实况5开始我使用最多的球队 就此告别世界杯 内德维德 比赛结束后镜头就一直拍他 意大利的每一位队员都走过来和他道别，拥抱…… 此情此景 怎能不令人动容 小黄的一句话 终于把在我眼眶中转悠的泪水催下 都是国际足联的排名 坑了捷克 所以我们虽然排名70开外 我们也不用伤心，哈哈 96年欧洲杯 我支持德国 为什么？ 是因为克林斯曼 如果有时间机器 我回到10年前的决赛 我会义无反顾的 支持捷克 哪怕 最后会收获和今天一样的伤心 June 19 DazukoDazuko是个内核模块，主要用于file access control，开源的反病毒软件clamav就可以使用它 之前还以为这个词来自日文 其实是德文 Where did the name "Dazuko" come from? Since Dazuko originated from a german company, it was felt that the name should somehow reflect something german. Dazuko's main function is to provide an interface for "file access control", or in german, "Dateizugriffskontrolle". Alles klar? Zaccardo这球那叫nb(第二版)youtube上的看不清楚，还以为是左脚踢到了。下面这是第二版： 首先，（和第一版不同，现在这一步是最重要的），要做好预判，把支撑脚（Zaccardo选择了右脚）放在适当的位置上，一定要保证左脚踢空之后，右腿可以到挡到球。而且要挡的恰到好处，厚不得，薄不得，出球角度大概只有45%。当然，如果布丰也是一伙的话，那角度估计可以达到90%吧。 其次，一定要抽一脚，以表示自己确实是要解围的。 再次，这一脚一定要有个提前量，一定不能碰到球。如果碰到球的话，鞋面和球面之间的摩擦力必定会令球向背离球门的方向运动。 总而言之，就是一句话：nb! June 17 forums.gentoo.org中文子论坛的charset问题一直需要手工改非常郁闷 我发了个email去问了下 原来不是加个charset=utf-8就可以解决的 因为不是每个子论坛用的字符集都是utf8 想想也是，如果都是utf8，早应该解决了 http://forums.gentoo.org/viewtopic-t-227013-highlight-utf8.html June 16 终于找到了这几句话的出处http://python.cn/pipermail/python-chinese/2005-September/015675.html 每日抽一个小时解答列表中初学者的问题， I need Rosetta, but Rosetta is not Open/Free Software, SHIT!
Synergy - One set of keyboard and mouse to rule them allhttp://www.linux.com/article.pl?sid=06/05/25/1439237 不错，哈哈 我现在就在用 如果有3，4台机器／显示器，估计更有feel 要注意的是配置文件里的机器名是hostname命令的显示结果 而客户端连接服务器的时候，要服务器的ip地址，或任何能解析成ip地址的机器名 June 15 HOWTO: Pick an open source license (part 1)HOWTO: Pick an open source license (part 1) by ZDNet's Ed Burnette -- If you write some code keep in mind that it's yours and you get to decide if, how, or under what circumstances, other people can use it. Let's say you've made the decision to release your code as "open source". What does that mean, what is an open source license, and how do you pick the right one? This question comes up all the time so I thought I'd write up a simple decision tree to try to explain the choices. June 14 [转载自smth]标 题: IEEE攻击WAPI的几个论点发信人: hitertan (享受工作，享受生活), 信区: ITExpress 标 题: IEEE攻击WAPI的几个论点 发信站: 水木社区 (Wed Jun 14 08:43:38 2006), 站内 认为还是说的很有道理的，不知WAPI有没有相应的反驳文章， 搜索了一下，只找到那篇不知所谓的“Unjust Activity, Undue Process, Unfair Results” 摘自http://grouper.ieee.org/groups/802/11/WAPI/11-06-0154-01-0jtc-fast-track-executive-summary-letter.doc ************* J1N7904 (WAPI) was also developed to strengthen the cryptographic mechanisms for WLANs. However, J1N7904 is not yet suitable for fast track consideration or approval, since it: ? Does not address the key requirements of the international community, as conveyed to China’s National Body over the last three years ? Has had no review by the international cryptographic community because the underlying cryptographic primitives on which WAPI is based are undisclosed ? Does not meet the technical and broad acceptance requirements for a WLAN security standard because: o It does not allow for the reuse of existing authentication technologies o It is not backward compatible with the huge volume of deployed ISO/IEC 8802-11 devices o It impedes portability of devices across national borders ? Has no known commercial deployment of the version of WAPI defined by J1N7904. Attempts over the past two years by non-Chinese companies to procure any version of a WAPI device have failed. ? Is incompatible with on-going and planned enhancements by IEEE 802.11 to WLAN technologies ? Contains contradictions with other international standards (e.g. ITU-T standard X.509) and impinges on the established scope of other ISO/IEC and ITU-T standards groups ? Is incomplete because it does not document the normative behavior of many exception cases, such as error processing ? Contains a large number of semantic ambiguities and syntactic errors, making it extremely difficult to discern the normative intent of the document These concerns are documented in detail in IEEE 802.11 document 11-05-1205-00. |
