7 simple-ish steps to green HTTPS on LAN with custom domain, Caddy, LetsEncrypt and Cloudflare. And a bonus tip!

Ever felt envious of those pretty green lock on sites like Github.com or Google.com? Ever wished to have one of those for services on your homelab? Well wish no more because I have a guide for you!

This guide is written for Ubuntu 16.04 server with domain registered on NameSilo and nameservers using Cloudflare. However it will work for any OS that Caddy supports (this includes Linux, Windows, macOS and many others on several architectures) and any other DNS provider with an API that Caddy supports.

What will you need:

1. $$ Domain
2. Cloudflare account, or account with other DNS provider with API listed in https://caddyserver.com/docs/automatic-https#enabling-the-dns-challenge
3. Basic understanding of DNS, server management and ability to RTFM

Generating Flame Graphs for Apache Spark

Flame graphs are a nifty debugging tool to determine where CPU time is being spent. Using the Java Flight recorder, you can do this for Java processes without adding significant runtime overhead.

When are flame graphs useful?

Shivaram Venkataraman and I have found these flame recordings to be useful for diagnosing coarse-grained performance problems. We started using them at the suggestion of Josh Rosen, who quickly made one for the Spark scheduler when we were talking to him about why the scheduler caps out at a throughput of a few thousand tasks per second. Josh generated a graph similar to the one below, which illustrates that a significant amount of time is spent in serialization (if you click in the top right hand corner and search for "serialize", you can see that 78.6% of the sampled CPU time was spent in serialization). We used this insight to spee

Turning Off Github Issues

My friend Michael Jackson turned off github issues on one of his smaller projects. It got me thinking...

Maintainers getting burned out is a problem. Not just for the users of a project but the mental health of the maintainer. It's a big deal for both parties. Consumers want great tools, maintainers want to create them, but maintainers don't want to be L1 tech support, that's why they
