It has been a while since I last posted, let alone update my infra a bit, so here's one quick entry to document it.
For the longest time I haven't enabled SSL on my blog or other HTTP sites; I used to use Comodo, then StartCom SSL. However, I got wind that StartCom (along with WoSign) will soon be distrusted by Google Chrome, et al. after some reviews of their operation. The good thing though, is that there's now a Let's Encrypt initiative which provides free SSL certificates, so I figure it is high time for me to re-integrate SSL once more.
