Customizing Coreboot on a ThinkPad X200 - 01: Background

Last summer I bought a ThinkPad X200 with the help of Jeff Bai. Since then I have been performing many firmware experiments (i.e. flashing and testing Coreboot) on it, and now I think it’s time to note down all my experiences, in the hope that people like you can benefit from them.

NETGEAR(R) ProSafe(R) GS105E Ethernet Switch Review

About several months ago I was considering buying a new gigabit ethernet switch that has 5 ports (so it’s small enough to fit even on my desk). I already had an unmanaged switch at that time – a TP-LINK TL-SG1005D, 5-port gigabit ethernet switch, but as I was planning to put some devices in the lab, I need another switch to allow more devices get connected to the same network. I searched for gigabit switches on Taobao, and at some time this NETGEAR GS105E switch appears in my eye.

Update 20191222: 咕咕咕！关于 MIPS 我 2019 年什么都没有做，而且短时间内可能也不会做。以下关于发行版配置的内容已经过时，现在我的想法又不同了，所以就当个 LFS 踩坑记录参考吧。先做些备注以免误导大众。

Connecting a CW Keyer to a Computer Using an Arduino Leonardo

Recently I take an interest in the amateur radio sports and I have been planning to get a license from CRAC for a month. Few days ago I bought a CW keyer (although I will not have the chance to operate on SW before I got the B license), but had no idea how to connect it to a computer.

Tor 实践

Tor 在这里*无论是直连还是接网桥都是已经做不到的了，尽管 Tor 的开发者一再声称 Tor 所使用的网桥协议 obfs4 可以躲避任何侦测手段，然而因为实现上的小缺陷（而不是协议本身，协议是完美的¹）现在墙也可以侦测到 obfs4 流量并进行拦截了，所以现在一个通行的办法是用 Shadowsocks 先穿出去，然后让 Tor 走 Shadowsocks 来连接洋葱网络。

My GnuPG Configuration

GnuPG (GPG in short) is a well-known cryptographic utility that enables you to encrypt and sign stuff using strong cryptographic methods (RSA, DSA, ECC, etc). GnuPG is also highly-configurable – that means you can modify its behavior easily. Here I want to share my configuration of GnuPG to you.
