个人操作使用记录

国庆&中秋。。
学生喜欢听音乐，几乎都是在线QQ音乐，貌似会造成网络卡顿，
一直想着给校园网加个播放音乐的功能，素材里有一些音乐文件，搜索一圈发现PHPwind论坛居然上个月就搬家了，不能登录当然也不能下载里面的附件，另外沪江的部落博客也貌似要关闭，留个邮箱看看能否导出日志
基本要求能够播放列表，能够随机播放更好，Codebase Hero 有个免费的music player 留一个邮箱即可下载，基于HTML5的jPlayer，有个中文的学习交流网站：http://www.jplayer.cn/developer-guide.html

解压后两个文件夹，demo里index文件，存放音乐的mix文件夹，和js文件夹里的playlist编辑列表文件
播放列表的样式参考：

代码： 全选

[
  {title:"My Sound 1",mp3: "media/mysound1.mp3", oga:"media/mysound1.ogg"},
  {title:"My Sound 2",mp3: "media/mysound2.mp3", oga:"media/mysound2.ogg", free:true},//free:true会在列表中此条音乐名称右边出现格式选择
  {title:"My Sound 3",mp3: "media/mysound3.mp3", oga:"media/mysound3.ogg"}
         ]

修改plugin里的2个js文件，把view more 改成中文“查看更多”，出现乱码，在demo里编辑index.html，加上utf-8的标识，两个js文件另存为utf8编码

[TeliuTe]

libreoffice calc 另存为并不会改变原来的编码，而是要点“保存副本”，然后就可以选择要保存的字符编码，
csv文本格式可以，而ods似乎不能改为其他编码，xls 覆盖时提示不能写入文件错误

Ubuntu 16.04 误删除所有内核，能进入grub2，不能进入系统的修复办法：

进入livecd 将另外一台电脑上的内核文件，用 scp teliute@10.0.5.250:/boot/* ./* 拷贝到本地，vmlinuz 需要用管理员权限，进ssh，用sudo复制到另外一个文件夹，用chmod 755 * 然后可以scp复制过来

代码： 全选

abi-4.4.0-83-generic
config-4.4.0-83-generic
System.map-4.4.0-83-generic
vmlinuz-4.4.0-83-generic
initrd.img-4.4.0-83-generic

修改/boot/grub里的grub.cfg，加入上面文件的引导，分区号改成自己的，uuid改成自己的

代码： 全选

menuentry 'Ubuntu' {
	insmod part_msdos
	insmod ext2
	set root='hd0,msdos7'
	linux	/boot/vmlinuz-4.4.0-83-generic root=UUID=3920776f-91de-4a06-83d7-23bd9a145d03 ro  quiet splash
	initrd	/boot/initrd.img-4.4.0-83-generic
}

重启后，登录，（进新立得，）重新搜索安装最新版内核

代码： 全选

linux-headers-4.4.0-96 (4.4.0-96.119)
linux-headers-4.4.0-96-generic (4.4.0-96.119)

存一个16.04上的grub.cfg，网速好慢，org已经上不来了

GIMP 的图片标注功能有些弱，没有好的方框、箭头、气泡这些图案，手工画的不好看
学生学习“截图和标注”这个知识点发现

代码： 全选

第11课 学会截图和标注

1、点菜单“文件-创建-屏幕截图”，选择区域，延迟2秒

2、按住鼠标左键，框选三个窗口，松开鼠标完成截图

3、选择文字工具，红色，分别输入“工具箱”、“工作区”、“图层面板”

4、新建图层，选铅笔，点一下出来一个点，挪开鼠标，再按住shift键显示一条直线，点第二个点，画出一个箭头，记住两点确定一条直线

5、方框用铅笔画也行，也可以用框选和勾画选区来画

gimp 的蒙版，白色是指颜色选白色可以修复擦除的图片，透明是可以看到下面的图层中的图像

Fedora22配置Fcitx搜狗输入法，发现显示搜狗状态栏以后，拖到最上面全局菜单时间旁边，然后就拖不动了，也点不动了，键盘切换英文后，可以正常显示，但是就是鼠标不响应
要想移动位置，就得到左下角系统托盘，右键，皮肤，换个其他皮肤，离开最上边的全局菜单栏就可以拖动了，难怪默认隐藏了搜狗输入法状态栏

全角的快捷键默认是Shift+space，很容易误按出现全角，可以在 Fcitx配置，全局配置，显示高级，切换全角里修改，这个地方默认禁用才对
点一下右边的shift+space，出来按键提示，按一下左上角的Esc键就可以取消快捷键，感觉这里用backspace或者del键要更好找一些

搜狗输入法打出字以后才会显示设置，刚切换过去还是显示Fcitx的“配置”，程序里找不到搜狗输入法设置，只能从托盘按钮，或者状态栏进入
等一会托盘按钮闪一下就好了，这时候又只能显示“设置”，不显示配置了，到所有程序里找Fcitx 配置，

代码： 全选

第9课 学会配置输入法
1、左下角系统托盘按钮，点击展开，键盘输入法图标，点击键盘切换输入法
2、按一下shift键，切换中文输入法，再按一下切换到英文输入法
3、在键盘上点右键，配置，或者点“活动，fcitx 配置”，点减号删除多余的输入法
4、点“全局配置，显示高级，切换全角，按ESC键，变成”空“
5、点”设置“，去掉”隐藏状态栏“的勾，从左下角拖到上边时间前边
