let's encrypt on apache & centos 7
I saw the HTTP vs HTTPS Test website earlier this week and was blown away by the performance jump between HTTP 1.1 and SPDY on a TLS-encrypted connection. With the introduction of Let’s Encrypt a few years ago, you no longer need to buy security certificates in order to provide a secure connection to your site - so I decided to see how long it would take me to switch my blog to HTTPS.
deploy jekyll site with git post-receive hook
I finally got a one-command method working for pushing updates to my Jekyll sites hosted on my VPS. A lot of this material is informed by Jekyll’s official how-to about deploying with git post-receive hooks, but I encountered a few gotchas that I thought might be worth going into a bit more detail over. The official how-to moves pretty fast.
