The article has nothing to do with atmospheric CO2, it is about using CO2 as a proxy measurement for virus transfer.

I have a $5 ESP32 board that does the same, my phone is just the UI!

snibsnib — Sat, 08 Nov 2025 06:21:07 +0000

I used to work in a paint lab. Things things that also affect perceived color include:

- Undercoat color

- Number of coats

- Gloss Level

- Size of colored area

- Surrounding Colour

- Combination of tinters used by each brand. (Different tinters can make colours metameric)

- Light Source (Incandescent, D65, LED, Fluorescent)

- Monitor Color Space (sRGB, DCI-P3)

- Color Space / Model used for conversion (Lab, Luv, Lch)

- Colour Difference dE Model Used (CIE76, CMC, CIE00)

- Precision and spectral range of the spectrophotometer used.

Etc

Its mathematically derived. A0 is exactly 1m2 in area. The side lengths are at a ratio of sqrt(2), that means you can cut any A paper size in half and get the size below it. B series are the same ratio, but B0 has a width of 1m instead.

GrapheneOS has Storage Scopes that does exactly this. (https://grapheneos.org/features#storage-scopes)

I'm not an expert in pharmaceutical chemistry, but this looks like a series of relatively complex and low yield reactions. Would it be likely that this would push the price of this product beyond what is reasonable for a general use drug?

I used to work in a paint lab. You are correct, oklch seems to be based off CIELCh.

Our eyes are much more sensitive to Blue/Violet, and less sensitive to green. There's a bunch of maths behind the perceived responses of our eyes.

If you're interested you can calculate perceived differences in the LCh colorspace using something like CIEDE2000.(https://en.wikipedia.org/wiki/Color_difference#CIEDE2000)

A Rainbow with equal DE between colors would probably look better than this one with equal DL.

A bit outdated now, but Saturn TAS made a very good TAS. It optimized door transitions to get the best in-game time. Unfortunately this was right as the rules changed between tracking in-game time and real-time, so the run never made it into the leaderboard. It made him stop making TASes for Super Metroid altogether. https://www.youtube.com/watch?v=y3THRhCgCO4

That bill is an amendment to the aforementioned act.

But yes, I'm confused as to whether it applies to online gaming, or sites such as wikipedia as well

Where i live, 80% of all vehicles are passenger vehicles. I'm not sure that the extra wheels on semis would make up for that difference, especially with the slow increase in size of passenger vehicles.

I used to follow the development blogs of the witness. I remember reading somewhere that accessibility was why you can beat the game with only 7/10 sections complete. You can completely skip both the colour puzzles and sound puzzles and still finish the game. Its an interesting compromise.

As someone who is colorblind, you are correct. Those puzzles are just about impossible for me.

I have read 'How to disappear', i don't think it would be very useful here. It's written by two private detectives to help people evade stalkers or family violence. It specifically recommends against breaking the law. In any case it would be a bit out of date by now.

It does support android cloud backups, but I usually have an encrypted export saved somewhere else.

Years ago I had a .bat file on a usb that ran Puppy Linux and Slitaz ISOs inside qemu. Although it didn't have working persistence.

Was a lot of fun, but people are more wary of letting you run random scripts on their pc these days.
