With the top facing up, and Ethernet ports facing away from you, i.e. the 4 console pins on the right bottom of the board, the pinout from left to right is (yellow,red,green for my personal setup):

openwrt kernel config change

In OpenWRT build, to change kernel config, you need to do the following:
1. make kernel_menuconfig CONFIG_TARGET=subtarget
This updates the .config file in build_dir/Linux-xxxxx
2. copy the file .config from the above directory to "target/Linux/your-board-name/config-3.14"
3. make V=99
The make command will copy the kernel config file from target/Linux to build_dir

golang vim-go setup

1. start with a fresh ~/.vim directory
2. install vim-plug if don't have it:
curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
3. add the following to your .vimrc file
call plug#begin()
Plug 'tpope/vim-sensible'
Plug 'fatih/vim-go'
Plug 'tmhedberg/matchit'
call plug#end()

au FileType go nmap <C-K> <Plug>(go-doc)
let g:go_fmt_command = "goimports"
4. inside vim, run "PlugInstall". This installs the plugins specified above. Restart vim. All plugins should be working now.
5. For vim-go, run ":GoInstallBinaries" to install missing tools needed by vim-go
6. Now Shift-K/Ctrl-K should run go-doc for the keyword under cursor.

 Note for go-doc to work correctly, the go source code file has to be in $GOPATH/src/package-name. It cannot not be a symlink outside of GOPATH. It cannot be a raw *.go file under $GOPATH/src either. It needs to be under a package directory.

windows 10 folder sort slow in file explorer

I solved this by unchecking the "Allow Files in the folder to have contents indexed in addition to file properties" option. You do this by first getting the Properties of the folder, then on the General tab press the Advanced button in the Attributes section. Apply the changes to the folder and , subfolders and files.
