Sample Chef cookbook and recipe that I created for a blog post on Chef

Hi 👋, I'm Doug

he/him / Philadelphia, PA, USA / 28% cheetah / #BlackLivesMatter

Welcome to my GitHub repo! This is mostly for personal projects that I've worked on over the years. Sometimes it's to learn a new technology, sometimes it's to contribute something to a particular space, sometimes it's just #CodePosting where I try something new.

If you like my work, please consider sponsoring me.

Here are my more interesting projects that you may wish to check out:

• Is PECO Okay? - Text-based low-bandwidth website for real-time information on the Philadelphia Power Grid. View on the web at https://www.IsPecoOkay.com/.
• Docker image to extract sound files from Star Trek: The Next Generation: A Final Unity
• Grafana Network Monitor - This is a quick and dirty collection of scripts and dashboards I built to monitor my home's Internet connectivity by pinging multiple hosts on the Internet.
• Docker in Vagrant - As a Mac user, I wasn't happy with the desktop offerings of Docker that were available to me. So I built my own using Virtualbox and Vagrant!
• FastAPI Httpbin - HTTP endpoints for testing. Heavily inspired by the original Httpbin project, with a few ideas of my own added in. Play with it here!
• Dead Simple QR Code Generator - Part of my FastAPI Httpbin project. No ads. No signups. No spam. Just QR Codes when you want them.
• Splunk Lab - Stand up Splunk in 30 seconds! It's a great way to learn Splunk, ingest sample data, etc. Includes the Machine Learning app.
• Grafana Playground - Spin up a Grafana instance with Prometheus and Loki for testing quickly and painlessly.
• Cheetah Bot - A Telegram Bot that makes cheetah sounds and posts cheetah pictures!
• Diceware - Generate passwords you can easily remember! Visit the Production deployment here.
• SSH Principal and CA Playgroud - Learn how SSH Principals and Certificate Authorities work in a Dockerized environment
• Script to convert JPG and PNG files to HEIC format - This script recursively converts JPG and PNG files to HEIC format, and will cut space savings in half. Useful for old photo archives!
• Undertale and Deltarune Resources 🌻 - A list of links of interest for Undertale and Deltarune
• Learn "git rebase -i" with this lab/playground - A tool I built to teach myself Interactive Rebasing in Git. Used for the talk I give here.
• ZFS Playground - Learn ZFS, the quick and easy way!
• WordPress with Nginx and Let's Encrypt - Collection of config to stand up WordPress with Nginx, MySQL, and Let's Encrypt. The blog post explaining all of this is over here.
• Septa Stats - Realtime dashboards and graphs of Philadelphia public transit. Visit the Production Website here.
• Splunk Network Health Check - A network health checking that I built. Uses Splunk Lab and a hacked version of ping(!)
• Is SEPTA F*cked? - Slightly more... colorful status website for Philadelphia public transit. Visit the Production Website here.
• Tarsplit - Split up tarballs on file boundaries to more easily use large tarballs in Docker images.
• evernote-to-obsidian - Wrapper for the Yarle app to make converting Evernote notebooks to Markdown easier.
• rsync-obsidian-to-icloud - Scripts to rsync your local Obsidian vault to/from iCloud so the mobile app can use it

mac-os-x-ipfw - Didn't work for me on OS X Mavericks

See basecamp/pow#432.

This command made it start working, but will go away on reboot: sudo sysctl net.inet.ip.fw.enable=1

Was going to send a PR, but I'm not sure the best way to fix it. You could add it in cookbooks/mac-os-x-ipfw/recipes/default.rb where you currently have this code:

execute "ipfw" do
        command "launchctl load -w /Library/LaunchDaemons/org.dmuth.ipfw.plist"
end

But that wouldn't stay past a reboot.

I found Apple's docs on launch daemons, but I couldn't see a way to run one process first, then run a second one that will stay running persistently.

You could wrap it in shell, but I'm not sure if there's a better way to handle it.

In any case, thanks for this recipe. If you haven't seen pow.cx, it's an interesting-looking tool. Not sure if it works with externally facing subdomains, or just .local ones.

I think this issue would be good to resolve, because I was banging my head against it for some time before I found sudo sysctl net.inet.ip.fw.enable=1.

Best, Peter
