  • 对课程根据活跃度进行排名
  • 统计课程中最活跃的用户
  • 等等
    • 添加一个local plugin的几个文件
  • index.php
  • version.php
  • lang
  • renderer.php
    • 遇到的困难
  • 插件不能安装——修改程序目录修正
  • 不能get_renderer——更改renderer的名字 前缀加上local后搞定
    • 一个比较恶心的SQL

    最近写了个爬去网站图片的python

    家里的网木有时间了 每小时3块钱 不舍得花了 不过还有个无线网卡可以用 但是流量只有3G

    恩 把脚本放到自己的windwild.net上跑就方便了么 把脚本放到服务器上 运行 发现断开ssh的时候 任务也终止了 这怎么搞 总不能一直连着吧 这样还是很浪费网和电

    去google搜发现一个好用的工具 screen

    主要作用就是能在ssh断开的时候继续执行任务 当你重新登录的时候显示原有任务的运行情况

    主要工作流程就是

    用screen运行程序
    screen python fotomen

    后台运行程序
    c-a d
    这是就可以断开ssh了

    显示所有screen的程序
    screen -ls

    回到某个窗口
    screen -r XXXX

    非常方便

    山寨了一个facemash
    做了个Gtalk的聊天机器人

    这三样东西技术含量都不高
    iOS的程序呢 完全是按照head first的指导做的 移动开发的前景越来越大了
    facemash呢 完全是因为爬到了很多人的照片才想起来做个这个的（工大网络管理员真是很多疏忽的地方 或者说是懒惰的地方）
    Gtalk机器人也是无意间看到的一篇文章想起来的

    iOS的我就不多说啦
    facemash过一阵子 我觉得代码写的好看一点儿的时候就扔到github上去 这个网站真的带来了很大的PV 第一版一个小时pv4000 第二版 一天时间6000 当然 照片换一换的话 我觉得会更强力的 如果挂上广告的话 肯定会是一笔不小的收入呢。

    升级么 一直对苹果很自信 先去软件更新里看 没有 由于升级lion之后 这个xcode是从app store上一点一点脱下来的 那就应该去app store上看看update么 结果 还是没有 看着app store上的版本 再看看自己的about 哭了

    最后搜了半天才发现 原来在应用程序里有一个install xcode的程序 一点 update出现了 开始更新了 终于。。。

    不过再一想 这么设计也是对的 xcode这么庞大的东西 想一次塞进去还真不容易。。。

    —–悲剧的分割线—–

    悲剧又来了 执行完application的install xcode之后 悲剧。。。。 版本依然是4.1 完全没有升级 只是重新装了一遍 好吧。。。囧 移除install xcode之后 在app store上可以重新购买了 好吧 苹果你也恶心了
