Whether you are a starving or established artist, we could all use a little mailbox money. Here’s how to get started:

I work at a small, privately owned company of 15 people. I am third in the chain of command. My direct boss has just put in his notice, and now I am in the odd position of having to hire myself a new boss. How do I make sure that the boss is the right fit?

Middle management is a damned-if-you-do, damned-if-you-don’t position. Stuck in the middle, you’re responsible for managing down to your reports, out to customers and clients, and up to your superiors. When it comes to delivering bad news, you’re the messenger most likely to be shot.

I’m an accountant for a small start up in Sacramento — not an HR manager. But, as often happens, HR issues tend to fall on someone, and that someone is me. The current team has been here since the beginning; we started the place. But now we need to hire someone. A stranger. How do I start?

If I wanted my 20-year-old son to join me for a late meal, I’d text him: “Buffet on me.” But I would never ever text my 86-year-old mother with a dinner invitation. For her, there would be a phone call with plenty of formalities and forewarning, a promise of a nice, sit-down establishment and a start time of 4:00 p.m. to take advantage of early bird specials. Why? Because each generation communicates differently.

Patent infringement lawsuits have long been the business version of a first world problem — a thorny matter for the Googles and Samsungs of the world. But in recent years, so-called patent trolls, shell companies that exist only to sue other companies for allegedly violating patents the shell company owns, have been going after much smaller businesses, from coffee shops to real estate offices.

Casey Marshall is hunched over his phone, furiously scrolling through his Twitter feed in search of a photo of  Waste Management’s promotional robot, whose broken axle he fixed back in March. “Someone came into the Hacker Lab and needed his robot repaired,” he says, grinning,  “and I was like, ‘I gotta do that.’”

Ryan M. Norman is the son of a pharmacist, raised in Vacaville with dreams of being an FBI special agent. When that path proved unlikely, he became an attorney instead.

You can dismiss someone from the conference room, but you may still have to face him or her in the living room.

As shopkeepers have done for thousands of years, Andrew Cook talks with his customers about what he ought to carry at the Utrecht Art Supplies store on Howe Avenue. The difference is that Cook, Utrecht’s assistant manager, holds the conversations on Facebook. The store had nearly 800 fans as of late November.
