It is not transparent though, so it doesn't work with all the other actions that use the cache toolkit, and you have to reference a specific action.

I was a bit confused by the section on backups. How do they manage moving the data offsite with the on-premises backup servers? Wouldn’t that be a cost savings by going cloud?

Isn't the iPhone SE basically that? Why didn't OP get the SE?

Important to point out this isn't just theory, it's actually happened (in the SF Bay Area!) with a regular rifle.

I’m in CA and got the same notice. But I checked the grid intensity and it’s emitting 146g/KWhr.

So the data might be wrong as well which may mislead the user.

On: Tesla has a range inflation problem

[EdJiang]

Because the drivetrain is several times more efficient, other loads have an outsized impact on mileage. The Model 3 is rated by EPA to be 131 MPGe.

So yeah -- if your drivetrain is getting 131 MPG, your A/C that consumes the same amount of power is going to have a much larger proportional impact.

There's also this guy who purchased a plot of land in the middle of nowhere, West Texas who's trying to terraform it into a forest.

No idea how feasible it is, but interesting to watch! https://www.youtube.com/@dustupstexas

Just subscribed! Very cool channel. Although his latest video outlining some of his experience with migrants in the desert is extremely heart wrenching. It's nice to see it from his perspective, as just another guy.

Huh. The link somehow changed after I submitted it. I wonder if you read the wrong article?

On: Ask HN: Slack shows a preview of private Google Docs?

[EdJiang]

It asks you to sign in and auth your Google account after sharing a docs link. So you give them permissions.

If you don’t want this behavior you can revoke Slack’s access.
