This device measures:
-CO2 concentration
-relative humidity
-atmospheric pressure
-temperature
I spent ~$200 on Amazon. It pairs with your phone and you can watch data come in every minute or so.

I recently bought one of these air quality monitors and got to take it out for some measurements!
I'll share some findings in this thread.
CCing @CO2Guerrillas here, in case they would like to share.

A great way to see how much clean air you are getting is to measure CO2 concentration.
Too high -> you could use more ventilation -> open some windows!
Outdoor CO2 concentration should be about 400 ppm. I haven't calibrated my device yet, so I measured ~470. Close enough.
<800 is good for indoors. Something like 2000 is very bad.

If I crack some windows, even just barely, it gets down to ~600 ppm very quickly, and my heater can keep the apartment ~70 F no problem.
CO2: 937 ppm.
Not great, not horrible. Surprisingly (to me), this place had the highest CO2 on my trip. It did have a purifier, which was nice.
~700 ppm. Still good.
650 ppm. Not bad!
Fun fact: this shop is 103 years old now.
Basically the same results in both: 650-700 ppm
620 ppm. Still not bad!
The doors open often, and the AC was on.
560 ppm.
Very nice! Especially since my device reads ~470 outside.
Took this sample in the essential ideology section.
520. Still good!
The whole store had their AC up very high. I could see many of the signs shaking due to airflow inside. I assume they were piping in outdoor air.
Follow these people instead of me to get some real science:

More from Tech
The first area to focus on is diversity. This has become a dogma in the tech world, and despite the fact that tech is one of the most meritocratic industries in the world, there are constant efforts to promote diversity at the expense of fairness, merit and competency. Examples:
USC's Interactive Media & Games Division cancels all-star panel that included top-tier game developers who were invited to share their experiences with students. Why? Because there were no women on the
ElectronConf is a conf which chooses presenters based on blind auditions; the identity, gender, and race of the speaker is not known to the selection team. The results of that merit-based approach was an all-male panel. So they cancelled the conference.
Apple's head of diversity (a black woman) got in trouble for promoting a vision of diversity that is at odds with contemporary progressive dogma. (She left the company shortly after this
Also in the name of diversity, there is unabashed discrimination against men (especially white men) in tech, in both hiring policies and in other arenas. One such example is this, a developer workshop that specifically excluded men: https://t.co/N0SkH4hR35

What is the difference between “pseudonym” and “stage name?”
Pseudonym means “a fictitious name (more literally, a false name), as those used by writers and movie stars,” while stage name is “the pseudonym of an entertainer.”
