Although the days of every site having an RSS feed have long past, I still find that it remains one of the few ways left to curate your own garden of content on the internet.

I subscribe to a lot of YouTube channels via RSS in NewsGoat, and the one thing that I can’t stand are Shorts.

A year after my last Neovim configuration post, I’ve made another significant change to how I manage my setup.

I’ve been using RSS to monitor single files or directories on GitHub and GitLab for a long time, and it still surprises me when people don’t know this is possible.

It’s wild that these days you can vibe code an entire app in the same time it would previously take to contribute a single feature.

2025-08-17 UPDATE: I’ve modified this post to use hooks.enter and hooks.leave after seeing how my previous solution was not working in all cases.

It’s been a while (3 months!)

A quick update about some new features recently added to FlyEmoji.

As I mentioned in my last post in my free-time I’ve been tinkering around with multi-player space themed game.

I’ve been playing around lately with procedural map generation and different ways to generate contiguous areas on a hexagonal grid.

Here are some notes on how my Neovim configuration management evolved in the last year.

The Partitioned attribute on browser Cookies is supported on Firefox and Chrome and these are some notes on changes I observed recently with it, and how these browsers handle Cookies.

I’ve been using Mise for some time now for both personal projects and work to manage versions of the tools used in my projects.

One of my emoji-based side-projects has button elements and centering emoji characters on them is a key part of the design.

I was building a site that uses QR codes that when scanned take the user back to the same site.

Server-Sent Events (SSE) are a simple way to send real-time updates from the server to the browser.

Tiny side-projects Lately there hasn’t been much time in my life for recreational programming but I still find time to create tiny services and put them on the public internet.

Occasionally, cmdchallenge.com would get into a state where requests to list user-submitted solutions to challenges would hang.

There are a lot of DevOps tools for managing both configuration and infrastructure as code.

Very recently I switched from running a couple side-projects that were hosted on AWS EC2 to a single Hetzner Cloud VM.

I’ve been slowly re-writing most of cmdchallenge in Go.

I’m pleased to announce that the transition from a distributed serverless architecture in Python to a single VM with a service written in Go is done for CMDChallenge.

I’ve been stealing small chunks of time in the evening here and there and finally have a functioning Go rewrite of cmdchallenge which will replace all of the Python code that is running in AWS Lambda.

I’ve decided to take what was written years ago for cmdchallenge.com and port it to a single Go app.

Command Challenge has been running for over 3 years now and I would consider it one of those “serverless” architectures.

HTTP API Gateway When HTTP API Gateway was announced in 2019 the Amazon said: Our goal is to make it as easy as possible for developers to build and manage APIs with API Gateway.

Recently we were looking at enhancing our deployment pipeline so that we run validation checks between every batch that is upgraded.

Recently a challenge was added that asks you to identify a process and kill it.

Say you want to display the contents of a file on the command line.

Hello world from the new blog using Hugo as the static site generator.

When I was learning to use the shell for the first time I remember teaching myself to do things as I ran into problems, and the first problem I ran into was how to take the output of one command and write it to a file or pipe it a second command.

One experience of mine, though it has roughly mapped to previous side projects: Wow this thing that has no business model is a cool idea, I wonder if anyone has done it before?

I’m writing this as a reminder to my future self never to use git submodules.

Yeah it’s another blog update, just really some style updates and looking back at something I did a long time ago and say what the heck was I thinking?.

In the process of making all of my private repositories public on Github and moving off of GitHub pages I have also decided to move most of my repos over to GitLab.

Today I decided to remove all private repositories from GitHub.

Have you ever thought about building a side-project for fun without spending a lot on hosting?

Adding to the interesting 191 ways to echo hello world I’ve now added the ability to see user-submitted solutions to cmdchallenge.

I was looking for a cool ending for cmdchallenge and decided to dust off a 2 year old javascript project which created a breakout game from figlet fonts.

It’s been about 12 days since the launch of cmdchallenge, a weekend project to create some common command-line tasks that can be done in a single line of bash.

Using data from page-watch.com this shows a time-lapse of reddit overnight on January 20th taken at 5minute intervals.

Before this year is over it’s time for a small redesign.

Hello world!

Below is a quick tutorial on how flask web framework might be used for simple highscore tracking.

Below is a recent weekend programming project that I did to play with canvas.

Here is a weekend hack that uses the midi to AVR conversion script and library.

“You’ve got a friend in me” played on an attiny85 and two speakers converted from a midi version of the song:

With an attiny13A, an IR motion sensor, and a candy Mario Brothers mushroom tin, this project turns them into a USB powered IR sensor that also blinks and sings.

Using an attiny13A and some leds and a speaker create a musical marioman.
