When it comes to VPNs, there is the choice between PPTP and OpenVPN. PPTP is pretty quick to setup and works out of the box with most (all?) OSes and devices.

These are the first steps you should perform on your shiny, brand new VPS to set out on a safe journey on the internets. You don’t actually have to understand each of the steps here, but this post is intented for people who have some clue of what they’re doing. If there is such a thing as a «VPSes for dummies», it should not be read. VPSes are not intended for dummies.

TL;DR: Varnish lacks support for SSL and SPDY. Nginx handles it just fine, and has very fast cache with either memcache or disk storage (ramdisk). Both can serve stale cache if your backend is down. But Nginx can not write to the memcache storage directly, it has to be done by the application. Also, Nginx can not purge the cache itself, without you compiling your own package.

OK, so I was ready to give Jekyll another shot today. But one thing I’m not that happy with is the need for specifying the YAML front matter on every post. At this point, I’m not really using it for any practical matter.
