A simple script to set up policy routing on linux. It's stateless and detects everything automatically, so all you have to do is to run it after every network subsystem change. I run it in postup and postdown hooks in Gentoo network configuration file.
#!/bin/bash
IP="/bin/ip"
function prepare_rt_table() {
local rttables=/etc/iproute2/rt_tables
local iface=$1
[[ "${iface}" = 'lo' ]] && return
if ! egrep -q "\s${iface}\s*"\$ $rttables; then
idx=$(wc -l <$rttables)

Best nginx configuration for improved security(and performance)
# to generate your dhparam.pem file, run in the terminal
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

This sets up keybindings in tmux that allow you to copy/paste to/from your OS X clipboard from tmux running inside an SSH connection to a remote host. Partially borrowed from http://seancoates.com/blogs/remote-pbcopy

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Partial functions in C This program illustrates a hack to create partial functions in C. The way it works is that it generates a template function (partial_template_function) with known pointers, that is later copied to a region of memory obtained with mmap(), patched up with the address and data to be passed to the real function, and then made …

挑戰龍的勇士
我崇敬挑戰龍而失敗的勇士，而不是皇帝。
我期待的是一種平衡，一種可以維持永久的，自然而包容萬物的平衡，將世界置於其中，然後，把發現者燒死。
我願意為機器賦予智慧，把所有人類的骸骨，變作空氣，把他們剩下的東西——如果有的話，完全消除。
我熱愛的統一已不在遠處，我來了，我來了，我會把整個世界，壓縮入一個原子之中，讓不存在的東西，歸於混沌。
我帶來的是劍，獻給我崇敬的挑戰龍的勇士。
