It's pretty wild we don't have laws that cover this
That's exactly why I never used it. Unfortunately I have family members who did so it doesn't matter that I avoided it.

I'm currently building an audiobook app. I've considered adding podcast (and even music) support, but wonder if this is something people actually want bundled together or would prefer tailored experiences.
I agree, focus on the audiobooks. That being said, I would love an app that can detect and skip the awful built in ads they've added to podcasts...

I've had a personal subscription to Claude for a while now. I would love if that also gave me access to some amount of API calls.

Really looking forward to 3rd party benchmark results.
Hoping to replace my i9-9900K this generation, but the Intel Core 9 Ultra 285K was incredibly disappointing, and the Ryzen 9 9950 wasn't that great, either.
Only 8 cores seems a bit of a let down, when the 9950 has 16, but apparently it parks half the cores during high load which seems to defeat the purpose of having so many cores, so maybe it's not a big deal.
Current rumor is that the 9950x3d will be released early next year. Personally I'll take less tdp, but I'm only using this system for gaming.

Chrome and Firefox use the OS dns server by default, which in most OS' have caching as well.

Outdoor CO2 levels can go up to 700-800ppm in rural areas due to plants creating CO2 [1]. I was initially surprised it's that high but it was verified with reference instruments.
Why measure CO2 outdoors?
We are able to detect emission sources pretty well now with our outdoor monitors [2] that have the SenseAir S8 NDIR sensor built in. You can see some real data in the blog post I wrote about launching our global CO2 map [3].
So setting up a dense network of these sensors in a city would allow to measure if for example the introduction of low-emission zones or switching to electric buses etc. would work.
Another use case is to check for leakage in underground CO2 storage facilities.
All-in-all it's still experimental (to some extent) but we know the accuracy is there and we can see more and more use cases as outlined in my blog post. So we now work hard to get more and more of these sensors out there to get more data to identify additional use cases.

It seems like ozone is the missing piece. The only ones that measure outdoor ozone are governments, and the numbers keep increasing.

The thing is, your drinking water in Aurora already comes from reservoirs in other parts of the state that have been fracking for years. Basically if you don't like fracking, you can't live in Colorado.
specto commented on Which Electric Cars Have Bidirectional Charging (V2L, V2G, V2H) zecar.com/resources/which... · Posted by u/teleforce
I have a time of use contract with hourly pricing, based on the day-ahead electricity market. So I also wanted to schedule charging, but I was somewhat disappointed that
- my charging station has no scheduling feature built-in
- my EV does have settings for this, but they act more as a suggestion. It would often charge when I didn't want it to.
Fortunately the charging station does support being controlled over modbus tcp/ip, so I was able to write some code and run it on a Rasperry Pi to control it. My control system fetches the prices and enables charging whenever they are below the configured maximum.
However, I now find that (because of my obsession with optimizing this) it is still very far from a hands-off solution. I find myself doing this:
- check electricity prices manually
- check car state of charge manually
- if prices are going to dip very low, figure out how much time will be needed to charge to 80%
- if prices are high, figure out whether I need to do a minimal top up anyway and how much, based on how much I think I'm going to drive
- choose a maximum price such that charging will be enabled during a sufficient amount of hours, based on the above
The main thing that's missing to properly automate this is a way to retrieve the EV's state of charge. But a charging station for home use will typically only support a simple PWM signal to tell the car how much current it can draw. No other communication is possible unless the charging station supports ISO 15118. Mine doesn't :-(
I use home assistant to charge automatically when I want, to the level I want. Though to make it work both my charger and car are somewhat supported by hacs repos.
