This is collected random docs I've written. Still a bit sparse, but I'll move over some other stuff here in the future.

• Bittorrent vs HTTP - a comparison of similarities and differences between the protocols
• curl vs libcurl - what are the different curl and libcurl really?
• curl vs Wget - a comparison of similarities and differences for ordinary humans
• Encrypted Transfer Protocols Compared - FTPS vs HTTPS vs SFTP vs SCP
• FTP vs HTTP - a comparison of similarities and differences between the protocols
• IPv6 - not quite docs but slides from a talk I did on this topic a long while ago.
• Meizu M6 vs Cowon D2 - how they compare size-wise with photos and all!
• poll vs select vs event-based - a comparison of the syscalls and the event-based alternatives
• SSH Through or Over Proxy - how to connect out to the Internet even though you're locked in behind a HTTP proxy

I have also participated within IETF and I am credited for my contributions to:

• RFC 6265 - HTTP State Management Mechanism (On my blog: The cookie RFC 6265)
• RFC 5854 - The Metalink Download Description Format
