##ss-redir 的 iptables 配置(透明代理)

透明代理指对客户端透明，客户端不需要进行任何设置就使用了网管设置的代理规则

创建 /etc/ss-redir.json 本地监听 7777 运行ss-redir -v -c /etc/ss-redir.json

iptables -t nat -N SHADOWSOCKS
# 在 nat 表中创建新链
iptables -t nat -A SHADOWSOCKS -p tcp --dport 23596 -j RETURN
# 23596 是 ss 代理服务器的端口，即远程 shadowsocks 服务器提供服务的端口，如果你有多个 ip 可用,但端口一致，就设置这个

libevent vs libuv

Comparing libevent and libuv. My upfront biased: I want to like libevent. However, I want to objectively compare the two and make an informed decision.

## Drift HD Ghost - Technical Notes and Root

Note: Please don't attempt anything here unless you are comfortable with the possibility of permanently damaging your camera. I also do not guarantee your camera is the same as mine - this is just for information and fun! It goes without saying that I take no responsibility for what you do with this information, and it will probably invalidate your warranty too.

It is reported that the firmware re-flash does not appear to disable the debug network on a Ghost S.

• Most of this was found by simply running strings over publically available firmware and software, then searching around for anything interesting.
• The camera runs on the Ambarella A5S chipset, which appears to run PrKERNEL (implementing uItron): http://www.esol.com/embedded/prkernelv4.html, then boots Linux as a process inside the uItron OS.
• There's lots of references to BOSS in the firmware, presumably a codename for this chipset from Ambarella.
• The code on the device-side is a very close im

Live Transcoding

This is a collection of working commandline examples to show how one could use FFMpeg and VLC for live transcoding of video streams. All examples have been tested on OSX 10.7.5 with FFMPeg 1.1.3 and VLC 2.0.5 in early 2013.

• FFMPEG multiple outputs
• VLC Docu, Advanced Use
