Spell check

use :set spell for checking spell errors.
use :set nospell for closing.

Programming Syntastic check

• Install Syntastic addon.
• Then use :SyntasticInfo to check the checkers.
• Take matlab code for example:
  add mlint to Path (or system link to /usr/local/bin/)
• use :Errors (:lopen) to check; :w to auto check.
• Enjoy coding.

Un-block Google Scholar for DigitalOcean vps

DigitalOcean’s ipv4 addresses are blocked by Google Scholar. We can solve this with ipv6.
To make it work:

• Enable ipv6 support in DigitalOcean online setting;
• SSH vps, add Google Scholar ipv6 addresses in /etc/hosts:

2607:f8b0:4007:805::100f scholar.google.cn
2607:f8b0:4007:805::100f scholar.google.com
2607:f8b0:4007:805::100f scholar.google.com.hk
2607:f8b0:4007:805::100f scholar.l.google.com

• In vps, restart shadowsocks:

sudo ssserver -c /etc/shadowsocks.json -d stop
sudo ssserver -c /etc/shadowsocks.json -d start

• update on Jul. 18, 2016. If Google Search is blocked, you may want to add two more lines in /etc/hosts:

2607:f8b0:4005:801::200e google.com
2607:f8b0:4005:801::200e www.google.com

• Enjoy.
