I mean, some of them do. Hertz's recent bankruptcy[1] and outlandishly...audacious[2] stock offering is one counterpoint. But it was a crazy year+ [1] https://www.marketwatch.com/story/bankrupt-hertz-shares-soar..

Did you miss the /s tag? You are actually trusting Uber's calculation, especially when they recently had to spend $250 million[1] to try to recruit new drivers? [1] https://www.marketwatch.com/story/uber-spend

It depends on who owns, maintains, and is paying for the vehicle and license/medallion to operate. The whole system - whether Uber/Lyft drivers who "relied on their unfamiliarity with capital depreciation calculations"[1

They do, but they buy or lease ordinary unmodified vehicles for a year or two then flip them at auction. Zero overhead here except for the buying/disposing of vehicles. $80/day is probably a decent estimate, but once you include t

The biggest issue for all of the self driving taxi service ideas is fleet maintenance. First of all, you need to own and insure a fleet of rolling depreciating assets. Maybe not as much these days with the crazy used car prices, but still,

A "SEV" (severity) is a production failure or incident, usually indicted with a level value. For example, a SEV 0 would be a total system unavailability incident, SEV 1 might be a major issue with parts of the system, SEV 3 is a l

Maybe only the right people use PGP.

The Signal protocol is very well designed but the implementation requires a telephone number (I know it is coming). That's a step removed from PGP which can be completely offline.

You're absolutely correct. But unless the tools are designed so the average user can easily manage their own keys, it's basically PGP again. I think U2F/WebAuthn dongles actually could solve this problem but there are all sor

This is pure snark and should be downvoted into oblivion, but by 2015 even Phil Zimmerman couldn't figure out the tooling: "Sorry, but I cannot decrypt this message. I don't have a version of PGP that runs on any of my device

Matthew Green does a pretty good job picking apart PGP's issues, although he completely fails at suggesting alternatives and also completely ignores non-email use cases. https://blog.cryptographyengineering.com/2014&#x2

Robo calls should be filtered at the network level. The Clipper Chip would have done nothing to prevent this. There is actually encryption technology[1] available that would solve this or at least make it traceable and blockable. But here w

PGP's biggest weakness was that it was too early. There was no normal user accessible software available. No regular person was going to establish the web of trust or use command line utilities. So now we have easy, strong encryption a

PGP felt so subversive back in the day. Key signing parties[1] and porting the "international" version[2] to run on the Amiga. And the very real threat that the Clipper Chip[3] would lead to the outlawing of all other encryption m

I don't know where you live, but that is way excessive for the developed world (minus wildfires). But as long as you are changing out those filters on a regular (3 months?) basis, you can go on being you and being healther for it.

In fact there are studies that show that even moderately high classroom CO2 levels are correlated with poor outcomes. https://pubmed.ncbi.nlm.nih.gov/25117890/

There are already makers that build heat exchangers, but there are a lot of catches and other unexpected impacts. Install a heat pump and/or geothermal.

Without adequate measurements, you would be surprised how wrong your advice is. If there are wildfires anywhere upwind, you're better off (barely) with the windows shut and recirculating the air through the furnace filter.

It isn't quite that easy. Even if there aren't impediments to opening a window a crack, it is not guaranteed that passive measures will reduce CO2 levels. I've been tracking my home office's CO2 level for about a year a

There are legitimate studies that correlate increased CO2 levels with decreased performance. https://pubmed.ncbi.nlm.nih.gov/25117890/

CO2 isn't toxic at CO levels and maybe not even performance impactful at 800 ppm, but there have been studies[1] that seem to indicate that even moderate levels of CO2 have measurable impacts. My personal experience is that CO2 levels

FWIW, this is my current temperature/CO2 plot: https://imgur.com/a/LhUoPcS The temperature graph is pretty easy to understand as you see the A/C kick on twice during the day. The CO2 level is maybe not as o

That's great advice and I will definitely look into it. I have a servo and a LCD panel on the same 5V supply as the ESP32, and while I think the USB power supply I have is sufficient, it is definitely worth investigating.
235.
by breput 5y ago
Yeah, that is more than adequate. When I posted my project online I got the not-unexpected feedback that the sensor was hard to calibrate. I don't care about 400 vs. 600 ppm. I do care about 600 ppm vs. 1600 ppm.

Do you see consistency between your CO2 detectors? Early on in the pandemic when I started working at home, I became very cognizant about the impact of CO2 and built a little project with a microcontroller and the MHZ-19B CO2 sensor. Calib

Do you recline while you're working or do you mean in between work? I'm just curious because I've napped in it a few times but generally keep it locked at a slight incline and almost forget how adjustable it is.

I was always an Aeron fan because it is a great chair but also it was also a status symbol. Back in 2011 I was working at a startup that finally started making real money and one day a semi truck showed up in the back lot and everyone rolle
