Have you ever seen weird indentations when doing code review? Mostly, the cause is that GitHub's default TABSIZE setting is 8 instead of 4 while some old code uses TAB for indentation. Fortunately, we can easily fix it by change this setting. 8 is not an ideal default TABSIZE nowadays, right? so it is all GitHub's fault!
Reference
put the following line in your ~/.bashrc or ~/.zshrc if you are using zsh
echo 2 | sudo tee /sys/module/hid_apple/parameters/fnmode
What? your sudo command asks your password? then
sudo visudo
#add this line
your-user-name ALL=(ALL:ALL) NOPASSWD:ALL
Don't you want to set this NOPASSWD option for security reasons? then put the following line into /etc/rc.local instead. It should work.
echo 2 > /sys/module/hid_apple/parameters/fnmode

/\cYourSearchKeywords case insensitive
/\CYourSearchKeywords case sensitive, which is the default behaviour
A few other ideas:
-
\c can appear anywhere in the pattern, so if you type a pattern and then decide you wanted a case-insensitive search, just add a \c at the end.
-
add set ignorecase for case-insensitive searching in my vimrc, and I can use \C to do a case-sensitive search
-
There's also set smartcase which will automatically switch to a case-sensitive search if you use any capital letters
- Remember!
set smartcase applies only when set ignorecase is already active

Yesterday, I need to replace a string ClassName with List<ClassName> many times in a few files, and the ClassName varies. Manually doing it again and again is tedious and mistake prone, which is what I hate. Here's the solution
First, record a macro,
- move cursor on any letter of the target ClassName
- qa
- ysiw>
- Insert
- List
- Esc
- q
Second, replay the macro, move cursor to another occurrence of ClassName,
@a
Third, replay the same macro as many times as you want: move cursor to any other occurrences, simply type

The feeling is so good to let a computer do what you want it to do!
and here's the Reference where I learnt how to use vim macro. TL;DR;
