windows10和ubuntu16.04双系统，仍然出现了喜闻乐见的老问题，装完后，在windows下时区不对，之前的老办法是：

sudo gedit /etc/default/rcS
utc=yes 改成 utc=no

然而并没有什么效果，ubuntu16.04里面根本就没有utc这一项！
后来谷歌了半天找到了一个完美解决办法：
先在ubuntu下更新一下时间，确保时间无误：

sudo apt-get install ntpdate
sudo ntpdate time.windows.com

然后将时间更新到硬件上：

sudo hwclock --localtime --systohc

重新进入windows10，发现时间恢复正常了！

但是在ubuntu24.04中，更新：

简单来说，在Ubuntu24.04中，hwclock已经被淘汰了，并采用了timedatectl去代替它。 因此我们可以在联网状态中使用下列代码实现Ubuntu与Windows的时间同步。

sudo timedatectl set-local-rtc 1

MACHINE: fish hunting
black pan: GND
red pan:
A: co1

press 100
    voltage change from 3.36V to almost 0V,and then come back to 3.36V
PRESS 10
    3.36V,0.9V,3.36V

B: HP

press coin return
    3.2V, 1.8V,3.2V

C: SSR

press coin return
    5.0V, 0.48V, 5.0V

D: TF

press coin return
    3.2V, 0V, 3.2V

运行

dong@ubuntu:~/octopress$ gem install therubyracer  

报错

ERROR:  Error installing therubyracer:
    invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /home/dong/.rvm/gems/ruby-2.3.1/cache/libv8-3.16.14.15-x86_64-linux.gem

corrupt:broken
the package is broken
so remove /home/dong/.rvm/gems/ruby-2.3.1/cache/libv8-3.16.14.15-x86_64-linux.gem
then redownload and reinstall
successed.

Got a lot of nightmares on those days.
So many bad things,bad days.
Got to carry on.

sudo apt-get install rar unrar p7zip-full p7zip-rar

1. 在添加/删除程序中彻底删除sql server
2. 将没有删除的sql server目录也删除掉
3. 打开注册表编辑器，在HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager中找到PendingFileRenameOperations项目，并删除它。这样就可以清除安装暂挂项目
4. 删除注册表中跟sql server相关的键

或者使用:SQL安装挂起解决工具免安装版.exe
DG：在安装盘C或D，搜索sql，会看到一个关于sql的编辑注册表项——SQL2000安装挂起.reg
