J1900 has no hardware switch. Every packet goes through CPU, so even LAN to LAN uses processing power. Add pfsense to the mix and it's probably choking.

A fathers day card from the dollar store. Include a gift card from the same dollar store. Put no money on the gift card.

Costco uses cost-plus pricing and caps its markup at 14% for outside brands and 15% for in-house brands (Kirkland). Other stores that use "value based pricing" are seeing some stuff marked up 600%. I only shop Costco a few times a year, but they are not where we need to focus on price gouging.

TNG, The Drumhead. The social commentary aspect of Trek without being too heavy on needing to know the SciFi lore of the series.

Any plans to port to Android? The artwork looks great but I would suggest to invest some time to un-Zelda it so you don't get the Nintendo curb stomp.
