I had to buy my own noise-canceling headphones for work. My cube neighbor on the other side of the wall is a hummer. When he starts humming, I'll put on the headphones to block him out. Once the IT department returns to the office, one of the IT directors will need to update the cubicle etiquette to include humming as one of those distracting sounds. Maybe, I'll just ask him to put his headphones on and hum inside his head.
Maybe a smart home security system. But my employer, a state agency, only gives performance based bonuses for large projects; I got a one-time bonus for helping plan and move our hosted servers over to the state's data center.
But I could use more DSLR and SLR camera gear.
