Even you set up the V2Ray correctly and cross GFW successfully, you will probably suffer low speed and high legacy. If you try to `ping` your server abroad, you will find the packet loss rate is high....

After Shadowsocks died, I'd been using Astrill VPN for some time. But it's not so ideal. The speed cannot be guaranteed and I always needed to try different servers to find one with fast speed. So again I decided to set up my own server to cross the GFW....

For a long time, Netflix has always been my pain point. I could cross the GFW to visit most of the blocked websites, but not Netflix, because Netflix will detect your IP address, and if they think you are using a proxy, you will be blocked when you are trying to watch the video (Netflix won't block you if you just want to broswer their website)....

Back to March this year when I come to the company I'm working for now I need to work on a project which use Svn for version control system. But I have always been using Git except for a very short time in my early programming life in 2012. I definitely don't want to use Svn again. Fortunately Git is so powerful that it can event interact with Svn repositories. ...

In CSS we could use either RGB values or hex code to set value of a color. But have you ever thought about *why* we could do this? At least for me I have never thought about such question until doing a related [challenge](https://www.freecodecamp.org/challenges/use-hex-code-for-specific-colors) on freeCodeCamp. ...

Once during a technical interview, I was asked to validate whether a sentence is a palindrome or not. But what’s a palindrome? A [palindrome](https://en.wikipedia.org/wiki/Palindrome) is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as "A man, a plan, a canal, Panama!", "Was it a car or a cat I saw?" or "No 'x' in Nixon"....
