---- emacs gist ----
git://github.com/defunkt/gist.el.git
# What's new in 1.0 ?
gist.el now maintains a local cache so as to not go to the gist server every now and then.
multi-files gist support (indicated by a '+' in the gist list)
improved gist-list buffer, based on tabulated-list.el (same codebase as package.el) New keybindings:
g : reload the gist list from server
e : edit current gist description

############### mongodb: ################
1) not master and slaveok=false
在写多读少的应用中，使用Replica Sets来实现读写分离。通过在连接时指定或者在主库指定slaveOk，由Secondary来分担读的压力，Primary只承担写操作。
对于replica set 中的secondary 节点默认是不可读的，
[mongodb@rac4 bin]$ mongo 127.0.0.1:28019

#### EMACS TIPS ####

### cscope: ###
;; * Keybindings:
;;
;; All keybindings use the "C-c s" prefix, but are usable only while
;; editing a source file, or in the cscope results buffer:
;;
;;      C-c s s         Find symbol.
;;      C-c s d         Find global definition.
