I’ve been playing a lot of the Risk Boardgame with my two boys recently. The game involves rolling dice to determine the outcome of a battle. While it was always clear to me that the attacker has an advantage when attacking with three dice, I was curious about how great the advantage is so I wrote some JavaScript code to calculate the odds.

JavaScript Idle Detection
Recently, I needed to determine when a website visitor was idle for a certain amount of time. I thought this was an interesting problem and wanted to spend a little more time with JavaScript so I wrote some code for it.
WP-CLI move site locally
These are the steps I follow when I move the database for a website to my local computer using WP CLI.
Activity Monitor find App behind Process Name
When working on my Mac, sometimes I find a process in Activity Monitor and I want to know what application the process belongs to. I was introduced to this command to do just that.
Checksum on Mac OS X Command Line
The checksum is like a fingerprint for the file. A file is processed through a known algorithm which results in the checksum, a.k.a “hash”, which is a string of letters and numbers unique to that file, e.g. 8ab686eafeb1f44702738c8b0f24f2567c36da6d. If the file is modified, the resulting checksum will be different. This allows a quick way to […]

WordPress Custom Editor Block
With WordPress 5.0 a new block-based editing experience will be introduced (a.k.a. Gutenberg). This new editing experience is available via the Gutenberg plugin. By adding this plugin to your (development) WordPress website, you can preview the new editing experience. At the time of this writing, Gutenberg is still under-development so I recommend only installing it […]
When command line “which” gives the wrong result
There is a very useful command line tool called which. This tool determines which file will be executed when you type it. Unfortunately, this command can sometimes provide the wrong answer. Update: I’ve recently been introduced to the type command, which seems to do what I want. You can jump to the section on using […]
Using Vim to View Git Commits
