Really hard to explain how do I feel about each of them. In no particular order:

• nginx: Probably what made me totally shocked. First I discovered it when I was trying to “reverse” some of the technologies that Facebook were using and I was wondering “what is this nginx dude, which is not lighttpd?”

• OpenBSD: Keep calm and <3 the puffy!

• x264: Dunno, was somehow very interesting. Specially with ffmpeg and a rtmp module on nginx.

• Bittorrent: Totally life-changer, specially after the emule era.

• Redis: Was[is] a lot better than ramfs.

• php: A non-C C interpreter. Love at the first sight?

• pf: Firewall said anyone? It’s just more than that.

• Assembler: Love / hate relationship. “I love you, I’ll kill you”

• Rust: We’ll see. Hype is gone and now it’s time for some real actions.
