Yes, just set up a sensor with home assistant (HA). Incredibly easy. Raspberry pi runs the HA server. The air quality sensor is attached to an ESP32 running ESPHome: https://esphome.io/#air-quality Almost plug and play. Com

Heres my set up: - 20 inch box fan - 20x20x4 MERV12 filter. The 4-inch pleating is key here, to reduce the air resistance on the box fan. - 1 inch dust pre-filter. This is course, low air resistance, and is for increasing the life of the mo

I don't think Craigslist gets used much for vacation rentals. Its certainly not well designed for that use case.

Those NCC/NCAs are unenforceable in California (outside some very specific exclusions, like C-level/founders), and California thrives, arguably because of it! I don't want my employer to be able to bully me into a contract wh

"mAh" are useless here without voltage. Its like using 50KM/hr as the towing capacity of a truck.

Thats not the right analogy. This would be more akin to selling your own bitcoins to yourself (into an IRA) for pennies on the dollar.

Seriously, the traditionalist argument is poor. You know what else humans have done for thousands of years? Slavery. And it also has many "religious" ties: https://en.wikipedia.org/wiki/The_Bible_and_slavery

I have many friends (and family) most of whom are in no way an alcoholic in AA, that hardly ever (or never) drink. Some just don't enjoy the effects, some prefer not to for health reasons, some just honestly prefer to smoke a joint. Th

Peking == Beijing. It’s the more phonetic translation of the mandarin name for the city.

This argument feels hollow to me. You may be right, perhaps we overvalue the purely economic contribution of biodiversity. But biodiversity is less of a means to me, and more of the end. Humans ARE biodiversity. We exist because of the long

I honestly don't know, can you tell me? One thing to consider is that Biden has been very public about transitioning US government fleets to all electric ( https://www.cnbc.com/2021/01/25/biden-plans-to-re

Their biggest customer may end up being the US government (eg. for work fleets). So maybe it was a strategic move? Time will tell.

Sure, but now you have to train your checkout staff to be experts in scratch off coating design. Retailers are definitely adding training material to help, but it still happens.

As I understand it, the gift card scam goes like this: 1. Perp steals the inactivated gift card, takes it home 2. At home, they scratch off the activation code, record it, and re-apply some scratch off coating 3. They reverse shoplift the g

I’m not familiar with the “vending machine” protocol he’s talking about, but it’s entirely reasonable that it has certain timing requirements. Usually the way you interface with these is by having a dedicated HW block to talk the protocol,

I think that 60% figure is misleading, it must represent people who have just come in to pick something up or drop something off. I'm working at another company in the valley, that is much more HW oriented, and its less than 10% of emp

Regenerative braking largely solves the brake pad issue. Some EVs are efficient enough that brake rotors rusting over from not being used is a concern.

Your comment may have been accurate 10 years ago when Silk Road existed, but nowadays people have moved on from bitcoin. The easily traceable ledger is a liability.

In most companies I have seen, you are given "refreshers" at a yearly cadence. So for example if you have an initial stock grant of $100K, vesting over 4 years (so $25k per year if split equally). Then at year 1 you might get anot
