Microsoft announced itsSQL Server on Linux public preview yesterday. I’m really excited to check it out. Here are some interesting things I found during my testing. I’ll write more as I play with it further.If you want to play it on Ubuntu,it needs to be 16.04 or above. I didn’t pay attention to that initially, and started installing on Ubuntu 14. Below is a typical message you would get:The following packages have unmet dependencies: mssql-server : Depends: openssl (>= 1.0.2) but 1.0.1f-1ubuntu2.21 is to be installed E: Unable to correct problems, you have held broken pa ...继续阅读 (48)

Below is a comment I made regarding Chinese leader Xi Jinping on Kaiser Kuo’s Facebook page, with very slight change.In my view, domestically, China under Xi is on the right path, unlike, say, Brazil, India, and the United States.I believe Xi’s a real believer of socialism and a real progressive. I believe his ideology and moral compass is very well aligned with that of Bernie Sanders and Jeremy Corbyn than Hillary Clinton and Theresa May will ever be. His heart is in the right place. I recommend this interview highly. It was done when he was the leader in Zhejiang province in 2004 ...继续阅读 (41)

I had some trouble setting up Run Configurations in Eclipse for PHP (PDT plugin). Here is my note for future reference.Machine: Ubuntu 15 64-bit, with Eclipse Mars. sudo apt-get install php5 installed apache2 for me, so no additional web server install is necessary.1. Enable userdir mod:sudo a2enmod userdir2. Your /etc/apache2/mods-enabled/userdir.conf should look like this, if not, make it so:<ifmodule mod_userdir.c> UserDir public_html UserDir disabled root <directory /home/*/public_html> AllowOverride FileInfo AuthConfig Limit Indexes ...继续阅读 (62)

给虚机设定了基本的防护措施后，我们来安装openvpn服务器终端并生成profile文件。以下指令都是root级别。我假定你已经通过命令行连到服务器上。请根据需要在命令行前自行添加sudo或变成root。我原计划给读者提供一步一步的说明，但那样会太繁琐。前两天注意到github上有人已经把这一切打包成一个shell脚本。我今天看了下，觉得写得很好。经过我成功测试后，推荐给你使用。并且这个脚本对Ubuntu，Debian, CentOS, RedHat啥的都管用。请到 https://github.com/Nyr/openvpn-install 下载openvpn-install.sh脚本文件；打开命令行，运行：bash /EnterRightPathHere/openvpn-install.sh脚本程序会自动探测到你的IP网址，按回车键；脚本程序让你选择DNS。我不建议第一个选项（Current system resolvers）。2和6均可.脚本程序让你命名客户端名字。默认是client。我不建议你用默认。建议你根据其所用的设备和数据中心命名，如androidFrankfurt，iphoneFrankfurt，或winPcFrankfurt等等。请用英文字母来命名；再敲一次回车，程序就开始运行。运行时间查不多三五分钟，请等待，稍安毋躁。运行结束后，openvpn服务器已经搭建完成 ...继续阅读 (211)
