You might have heard that although salt is very common, growing crystals with it is hard.

Yes, and no. Growing big, transparent salt crystals is indeed very difficult, but anyone can easily grow a beautiful cluster at home.

But while there are many tools to automatically renew certificates for publicly available webservers (certbot, simp_le, I wrote about how to do that 3 years back), it's hard to find any useful information about how to issue certificates for internal non Internet facing servers and/or devices with Let's Encrypt.

I want to detail some techniques you can leverage to make your Maven builds faster in this post. The following post will focus on how to do the same inside of Docker.

I love spreadsheets. Spreadsheet programs like Microsoft's Excel, Apple's Numbers and Google Sheets are the secret heroes of our civilization.

I've also been interested in personal finance and the FIRE community for a while—not so much in the early retirement aspect but in the financial literacy it teaches its members.

So you're all done recording your next song. You've laid down final takes for all the tracks, mixed everything and decided on the final master. Congrats!

So I wanted to write about using Firecracker from a more DIY "I just want to run some VMs" perspective.

I'll start out by talking about what I'm using it for, and then I'll explain a few things I learned about it along the way.

Pick a muscle, get suggestions for exercises that address that particular muscle.

Nim is a powerful statically typed language that allows the programmer expressiveness without compromising run-time performance. As a general purpose programming language, it gives the same sort of power and performance as C++, but in a nicer package and with even more powerful tools!
