Do I know anyone who has successfully taken a UK passport photo themselves (instead of going to a shop)?

Does this puddle suggest that my wiper fluid reservoir broke? Or something worse?

Just read two different manuscripts that are both VERY GOOD. Sometimes all the hassle seems worth it

Ok I find it odd that they decided to park the pickup trucks with the salt supply in the N and S lanes right opposite each other on the middle of the bridge, creating a bottleneck for the cars, whose drivers will surely blame "the bike lanes".... But they moved one of the trucks after a few minutes :)

A+ for... Not sure who is responsible for the safety of the bike lanes on the Mass Ave Bridge, but they have a contractor putting road salt in the bike lane and pedestrian walkway to prep for the storm coming tonight, so bravo! #Boston

When I went to Burdick's in Coolidge Corner. I was wearing a respirator, but my friend who was drinking hot chocolate and eating cake wanted to leave when they saw these numbers, so we went for a walk.

We can't smell or taste or hear high levels of CO in indoor air. But with these monitors from the library, we can find out -
Hey, if I have six people breathing in my living room, and I crack two windows, the CO2 numbers are as low as if I had one person breathing in the room with the windows closed
Or
Hey, this grocery store's ventilation system copes a lot better with the crowd at 8 pm than the crowd at 6 pm

So why does CO2 ppm matter?

Here's an interesting way to play with CO2 monitors in an interventional way, not just observational: go in your car, keep breathing, and play with environmental variables - windows open or closed, ventilation set to off/recirculate/outdoor air.

For example, I took this pic right after leaving a grocery store. That high above the background level? When I was in the grocery store, about 2% of the air around me was recently exhaled by the other people in the store.
I like people but I don't like them that much! Especially right now, when we know from CDC data that New England is still at the "very high" level of SARS-CoV-2 in our region's wastewater.

This restaurant isn't near that level right now, but a lot of grocery stores, bookstores, restaurants, and also cars and homes can get CO2 ppm concentrations that are way higher.

The CDC has a webpage about using CO2 monitoring to track and improve ventilation; they said to consider supplemental air filters when the CO2 ppm is above 800.

Then I went inside to pick up takeout. Now the CO2 ppm reading is 577. That increase from the background level? That extra CO2 in the air in the restaurant might have come from the customers and the workers breathing out, and from the gas burners in the kitchen.
577 is higher than the outdoor number, but it's also quite low indeed for an indoor space.

Some basics about CO2 ppm (parts per million):
There's some CO2 in outdoor air; my monitor is reading 433 right now in Washington Square. Think of that as the background level. Not great in terms of climate change, for sure, but this thread is about CO2 and indoor air quality/ventilation.

The Brookline Library has ten CO2 monitors; eight of them are currently on the shelf waiting for you to pick them up and take them home (or out and about) for a couple weeks.
Four in the main library in #BrooklineVillage
Two in the branch in #CoolidgeCorner
Two in the branch in #Putterham

Guess what! The Brookline Public Library has CO2 monitors that you can borrow! Very useful for checking out the ventilation in any indoor space that is ventilated (mechanically or naturally) with outdoor air. FREE!!!!!

How do people get books they have written and typeset printed on demand these days? In small quantities?
I loved the "Gutenborg" Espresso print on demand machine that Harvard Bookstore in Cambridge used to have! But in its absence I am interested in local to Boston, or online / mail options.
Not even sure what tags to use TBH
