发两个在linux下折腾的结果 linux的意义在于折腾

程序代码：

#!/bin/bash
# sunpinyin_speed_up.sh
# Sunpinyin Speed Up Script for Ubuntu (by memory caching, and no data loss)
# You can run this script in background on GNOME logging in.
# Originally written Hubert Star, modified by Bob Robot (http://).
# Modified by zklhp.
# Capture the exit signal, make sure it is the FIRST uncommented line.
trap "do_exit" SIGHUP SIGINT SIGQUIT SIGTERM
SUN_DIR="${HOME}/.sunpinyin"
SUN_DIR_BACKUP="${HOME}/.sunpinyin_backup"
SHM_DIR="/dev/shm"
SHM_SUN_DIR="/dev/shm/.sunpinyin"
# Backup the userdict and restore all changes made by this script on exit.
do_exit() {
    mv -f "${SHM_SUN_DIR}" "${HOME}"
    rm -Rdf "${SHM_SUN_DIR}"
    rm -Rdf "${SUN_DIR}"
    mv -f "${SUN_DIR_BACKUP}" "${SUN_DIR}"
    exit 0
}
# Work around for abnormal quit.
if [ -e "${SUN_DIR_BACKUP}" ]; then
    rm -Rdf "${SHM_SUN_DIR}"
    mv -f "${SUN_DIR_BACKUP}" "${SUN_DIR}"
fi
# Rename the real userdict, copy it to RAM and make a symblic link back.
# From now on the modification and query on userdict takes place in RAM.
cp -Rf "${SUN_DIR}" "${SHM_DIR}"
mv -f "${SUN_DIR}" "${SUN_DIR_BACKUP}"
ln -sf "${SHM_SUN_DIR}" "${SUN_DIR}"
# I start fcitx here.
fcitx
# Automatically backup the userdict, make sure not losing the modification.
p_count=0
while [ true ]; do
    p_count=$(($p_count+1))
    sleep 1800
 
    if [ $p_count == 2 ]; then
    p_count=0
    cp -Rf "${SHM_SUN_DIR}" "${HOME}"
    fi
done

解决了sunpinyin用户词库慢的问题根据网上的一个代码改写网上的代码只是把用户词库文件放内存了但那样一旦对用户词库做插入操作SQLite会生成一个journal文件而当用户词库比较大的时候这个文件在硬盘上的话是很慢的于是整个目录全部放在内存里面

该方法有一定的危险性建议使用前做好备份这样的话在我这里还是会卡的只不过卡1秒基本不影响使用就是了

这个方法的通用性比较好可以推广到其他因为硬盘效率低而影响流畅性的软件上前提是内存足够

第二个 linux下的emacs打开最大化或全屏

程序代码：

(if (string-equal system-type "gnu/linux")
    (progn
      (add-hook 'after-make-frame-functions
        (lambda (new-make-frame)
          (select-frame new-make-frame)
          (set-frame-parameter nil 'fullscreen 'maximized)
          )
        (set-frame-parameter nil 'fullscreen 'maximized)
        )
      )
  )

maximized 改成fullboth就是全屏改天试试windows下好使不好使。。

打完收工
