He/Him. Happy husband, proud father, retired physicist, forever coder, and avid gamer. Interested in everything. Addicted to roleplaying game systems, so I have a considerable (and growing) collection…
I implemented impairments in my HMK Toolkit app for HârnMaster Kèthîra, then I added the ability to swap hands, because you might have impairments in one arm and want to use you other arm to swing your sword. Turned out to be pretty complicated but I really like the result!

I added a quick roller for HMK Toolkit, my HarnMaster Kethira application. It finds the EML, rolls the D100 and interprets the result either as a Skill Test or as a Skill Value Test.

Apologies to all who were affected by the session expiry bug! Ideally I’d reset the trial periods of all affected, but the App Store doesn’t allow that.

So instead, if you experienced the issue and started a trial before today, you can grab an extra free week.

Aeronaut 1.3 should be rolling out to the App Store now! It’s mostly bug fixes—including a comprehensive fix for the session expiry issue—but I also snuck in tab switching keyboard shortcuts, so you can now switch tab with ⌘1 through ⌘8.

A new tool for HMK Toolkit, my macOS app for HârnMaster: Roleplaying in the World of Kèthîra. It is used at character creation for mages (called Shek-P’var) to select their spells.

I’m experimenting with an implementation of the layer rules for armour in the HarnMaster Kethira TTRPG for my HMK Toolkit app. It was interesting to code and will be a very useful addition.

I'm terrible at self promotion. I spoke with the HarnWriter's team that worked on this quarter's HarnQuest publication, The Silver Conspiracy!

A nice departure from the trad article format - something of a scenario, but Harn style. www.youtube.com/watch?v=K9K2...

Bud was a friend. My last words with him were scheduling our next Delta Green session of God's Teeth (we were about to begin the finale). None of us imagined we'd never speak again. I'll miss him.
