Pi-Hole & DNS over HTTPS
There are some cool things about running your own DNS server. I use it to reference some web services that I run internally more easily, like my Unifi Controller, PiAware, and my home-grown Linux Server. It’s a lot easier than trying to keep track of the IP addresses of everything in your network. For that…

Code Complete Notes, Chapter 3, Section 5: Architecture

Code Complete Notes, Chapter 3, Sections 2 and 3
Defining the Problem Section 2 of Chapter 3 is very simple: you should know what problem you’re trying to solve before you try to solve it. It normally shouldn’t be stated in technical terms. Instead, it should be the simplest issue that you’re trying to solve. For example, “We need developers to be able to…

Code Complete Notes, Chapter 3, Section 2
Different types of software require different types of planning. If you’re working on your own blog, for instance, the stakes are a lot lower than if you’re working on, say, an automated flight control system. If you’re working on one of those high-stakes projects, your planning should be much more thorough & much less iterative.…

Code Complete, Chapters 1 and 2
Hello, everyone! I’ve recently started reading Code Complete (the second edition), by Steve McConnell. I haven’t made it very far into it yet, but I figured that I’d share the things that I learn or find interesting here. I realized that when I read, it helps me to take notes and focus on highlighting so…

Using `xarg` to pass to `find`
I just found myself needing to run wc -l on all the files in a list of directories – in my case, I had a big old list of directories with a matching name. But I wanted to calculate the total number of files in those directories. Unfortunately, find is very particular about where its…

Creating and Applying Diffs with Rsync
At work recently, we had a need to generate diffs between two different directory trees. This is so that we can handle deploys, but it’s after we’ve already generated assets, so we can’t just use git for the diff creation, since git diff doesn’t handle files that aren’t tracked by git itself. We looked into…

Saving Calculated Fields in Ruby on Rails 5
In Ruby on Rails, it’s easy to build custom functions to calculate something and then display the result in your views. While this simplicity is nice, it doesn’t come without its drawbacks. Recently, when working on a simple app, I came across a situation where loading a page was taking 0.5 seconds. This may not…

Many-to-Many in the UI in Ruby on Rails 5
I know I’m really late to the party, but I’m just finally creating something from scratch in Ruby on Rails. I’ve dealt a tiny bit with Rails before, but it was mostly just in helping my brother with CSS stuff, which obviously isn’t working on the Rails backend. Anyway, now that I’ve started working with…
