We've managed to keep our house smoke-free this year. Important because my son has asthma. Here are my tips:
1. Find and seal all the places where air can enter your house. Old leaky windows. Bathroom, kitchen, laundry fans might vent outside. Attic drop-down doors. 3M sells a window insulation kit that's 💯. amazon.com/3M-Indoor-Insu…
2. Not all air purifiers are created equal. Last year I had whatever was at Target. This year I bought Wirecutter's picks: Coway Mighty and Blueair 211+. Both are working very well. nytimes.com/wirecutter/rev…
3. I don't trust sensors on air purifiers, so I bought the Purple Air indoor air sensor.
4. Check if you can run your AC, ideally with a good filter for PM2.5. Don't run an air pump that draws air from outside. Don't run AC with big gaps in the ducts that let in air under your house or in your attic. Test it first.
5. When air is good, let in as much fresh air as possible. I rely on the Purple Air map because it's much more real-time than any other source.

Folks often ask me what I do at work. What even IS an engineering director? I don’t write code all day anymore, so it seems very mysterious. Here’s my answer: people, processes, priorities.
(1) People. Hiring, career growth, happiness, performance management, compensation, team culture, psychological safety, coaching the managers in my org. This is perhaps the most visible and obvious aspect of management.
(2) Processes. Are we making good decisions in a timely manner? Are we looking at the right metrics for launches? Are we planning and executing well? Is the product team far enough ahead of engineering? Are our technical decisions taking the right factors into account?
Achieving Mindfulness: An Introductory Guide For Parents In Small Apartments & Crowded Homes 🧵
1) Start your mindfulness journey with a shower. Count to three as you breathe hot steam in, then let it out. Stay in the shower until a child breaks a limb or your spouse’s spirit, whichever comes first.
2) Repetitive tasks free the mind from worry. Luckily, you can practice mindful repetition in your own home! Sixteen times a day, your children’s insatiable hunger gives you the opportunity to slather peanut butter on celery. After 6 months, you'll be COMPLETELY FREE FROM WORRY.
At-home preschool is getting intense. Does anyone know the name for a number that can be factored into a step shape? Also, is there an O(1) algorithm to check if any given N is a step shape? I'm stuck
Triangular number, thank you!
Huzzah, testing if 8x+1 is square is easy to do in my head and works
Tried to teach the dog the command "drop it" by offering him a treat if he dropped it. Now he searches for important things, brings them to me, and holds them hostage in his mouth until I give him a ransom
Two Berkeley PhDs and Google engineers in our house, and the dog is smarter than us both
here is a photo of our master criminal with his head stuck in a box
