I've finally finished Super Saiyan mode of my home audio setup, which I spent MONTHS researching starting when the pandemic happened. Won't fully detail it here, but if anyone is curious, hit me up. I'll give you three hints though: Genelec, NAD, and DIRAC Live. I've been having so much fun listening to both my favorites and tons of new music as well. I honestly think audio gear is some of the best money you can spend if you're into music. Some of the other best money? Bidet toilet seats and a top-end mattress.

The next time you interview for a job, ask your potential new manager these five questions:

  1. When was the last time you promoted someone on your team? How did it happen?

  2. Why did the last person in this role leave?

  3. How do you nurture psychological safety in your team?

  4. When was the last time you supported a direct report's growth, even if it meant leaving your team or company?

  5. Most/all of my interviewers were men. Can I speak to some women on the team to hear more about their experience?

These come from this excellent Twitter thread by Lily Koning, and thanks to Jason Haddix for the retweet discovery.
