So DOGE-related cuts and early retirements eliminated 550 staff at the National Weather Service, and now the NWS is being granted special permission to hire 450 positions to relieve critical shortages. Such a waste of time and resources.

Want to create chaos?!?!? Make your gateway IP addresses something other than .1 Even more chaos? If you have multiple subnets/VLANs, don't make it uniform, .73, .212, .29, .89, etc...

It’s a long term goal of mine to make a cyber conference for my fellow Mainers. In reality we could probably put it anywhere 🤣 as a lot of us no longer live there, but it would be for us and it would be glorious
