夢

Posted by Csineneo on 2011/10/02, 05:59:50, UTC+8

狂躁的梦境陡然间结束，激昂的心跳瞬息间平缓，纷叠的记忆呼吸间逝去。
梦已逝，悲欢尽，夜迷朦，君何在？

Opera snapshots checker v3

Posted by Csineneo on 2011/09/27, 08:08:29, UTC+8

以前寫的 checker 都是 php 的，早起無事，折騰下，用 shell 重寫個。

  1. #! /bin/bash
  2.  
  3. url=http://snapshot.opera.com/windows/latest
  4. dir=/ls.tl/check
  5.  
  6. win=`curl -s -I $url | grep Location | awk 'BEGIN{ORS=""} {print $2}' | tr -d '\r'`
  7. #eval `echo $win | awk -F '[-|_|/]' '{print "codename="$5, "ver="$6, "build="$7 }'`
  8. eval `echo $win | awk -F '[-|.]' '{ print "ver="$(NF-3)"."$(NF-2), "build="$(NF-1) }'`
  9.  
  10. if [ ! -f $dir/build ]
  11. then
  12.     echo 0 > $dir/build
  13. fi
  14.  
  15. if [ $build != `cat $dir/build | awk 'BEGIN{ORS=""} {print $0}'` ]
  16. then
  17.     echo -n $build > $dir/build
  18.  
  19.     mac=`echo $win | awk 'BEGIN{ORS=""} {sub(/windows/, "mac"); sub(/exe/, "dmg"); print $0}'`
  20.     unix=`echo $win | awk 'BEGIN{ORS=""} {sub(/windows/, "unix"); sub(/Opera.*$/, ""); print $0}'`
  21.  
  22.     echo -n '<h2>Opera '$ver' build '$build'</h2><ul><li><a href="'$win'">Windows</a></li><li><a href="'$mac'">Macintosh</a></li><li><a href="'$unix'">Linux/FreeBSD</a></li></ul>' > index.html
  23.  
  24.     echo -n -e $win"\n"$mac > $dir/dllist
  25.     wget -q -N -P $dir/builds/ -i $dir/dllist
  26.  
  27.     date +%s > $dir/timestamp
  28.     echo -n 1 > $dir/update
  29. else
  30.     date +%s > $dir/timestamp
  31.     echo -n 0 > $dir/update
  32. fi

嗯嗯，只有 php 的三分之一長

—
update – 2011.09.29
1076 更新时 codename 与 ver 之间插入了 “opera”，考虑到以后还会再有变化的可能性，改为从文件名中匹配版本号

  1. eval `echo $win | awk -F '[-|_|/]' '{print "codename="$5, "ver="$6, "build="$7 }'`

改为

  1. eval `echo $win | awk -F '[-|.]' '{ print "ver="$(NF-3)"."$(NF-2), "build="$(NF-1) }'`

地球不是繞著太陽轉的，地球是繞著太陽系重心轉的，太陽系重心並不總是在太陽内部 =.=!

最近用 Amazon EC2 搭了不少環境，記之，以備日後查閱。

Debian 6.0.2 / Nginx 1.0.6 / MySQL 5.5.15 / PHP 5.3.8 編譯安裝。

零－初

  1. apt-get update
  2. apt-get upgrade
  3. apt-get install build-essential vim
  4. cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
  5. echo '/dev/xvdf   /www    ext4    defaults,nosuid,noexec,nodev 1 2' >> /etc/fstab
  6. mount -a

乾淨安裝 Lion 10.7.1 之筆記

Posted by Csineneo on 2011/08/28, 02:49:47, UTC+8
  1. 從 AppStore 下載 Lion 10.7.1。按住 Option 點選 purchased 即可重新選擇安裝。
  2. 下載完畢後取消安裝，從 “/Applications/Install Mac OS X Lion.app/Contents/SharedSupport” 中提取安裝鏡像 InstallESD.dmg
  3. 燒製鏡像到 DVD 或恢復鏡像到其他分區／U 盤
  4. 重啓，按 Option 選擇引導設備，按提示安裝即可

走到最後一步時出現若干問題：

  1. 安裝完重啓後出現禁止圖標。Google 一下，大神說這是黑蘋果的典型問題，坑爹呢 =.=!
  2. 再次重裝，安裝程序引導失敗，只是提示“請嘗試再次安裝”。再問 Google 大神，找到一靠譜的答案，參照官方文檔清空 NVRAM (登陸到系統後可使用 nvram 命令讀寫 NVRAM)，搞定
  3. 以上兩個問題出現的根本原因是把 Lion 裝到了加密分區上，只能先裝到非加密分區，進入系統後再啓用 FileVault
  4. 系統分區亦不可使用大小寫敏感的，否則諸如 Photoshop 之類的 Adobe 系軟件是無法安裝的。話說正是有了上次使用大小寫敏感文件系統的經驗，才有了這次的系統重灌 =.=!

是以為記。
