What band is that? Also how do they do that? Just heavily compressed mp3?
The enshitification I mean, applies to the new models. Once the current device dies, you need to replace it.

And in the future, the offline devices might be no longer available, because they stopped being produced. And only new shittier ones are for sale.

Firewall blocking is not the point. The point is, that over time through enshitiffication the new device will require call home to unlock. Even when it does not need internet to work at all. But through this the vendor will get a foothold.

Sure you can block it, but then you have a pricey paperweight.

This is not unique to Thread/Matter, they can pull the rug on ZigBee as well, ofc.

Re:Self-Powered Trailers Promise Leaner Freight Runs on Monday July 20, 2026 @03:40AM (#48975443)
This trailer saves 7000l of diesel per year. Assuming 40l/100km, with this trailer you can go ~17.000 km more, which is 11-17% more, for the same fuel cost. Or ~12-15k EUR in fuel savings per year (assuming 1.8EUR/l).

With 13+ years ROI (electricity is not free) is this really beneficial?

Re:Should you normalize RGB values by 255 or 256? on Tuesday June 02, 2026 @09:51AM (#48370268)
> index 0 holds values from 0-1, index 2 from 1-2 etc,

Well, now you are double counting the end values of the ranges. In your example 1 is included in both 0-1 and 1-2.

Doesn't soy mimic estrogene, thus causing potentially other issues?
Sure, but are they running audio recognition and image recognition models on each upload just to classify it?
How is TikTok able to screen this en masse? Are they going after tags? Political issues aside, I am really interested in the technical background in this.
There is https://explainshell.com/ not in terminal but should do the trick.

In tutorial, it did not accept HIM as a solution, because it wanted DIM. Kinda confusing.
Firefox on Android has UBlock Origin available. But that covers the browser only. I guess AdGuard and VPN might help here?
Re:A startup’s quest to store electricity in the ocean on Friday November 07, 2025 @07:18AM (#45845655)
Oh, right thanks for clarification. They are indeed not pumping just any salt water, but much heavier brine (which they get who knows where).

So if there is any leak in the system, it will kill local wildlife right, like the brine pools under ice in Antarctica.

Re:A startup’s quest to store electricity in the ocean on Friday November 07, 2025 @05:40AM (#45845175)
How exactly are they pushing the brine against the ~50BAR pressure differential?

They mean the intersection between the cone produced by the satellite and "illuminated" surface. If the antenna beam is normal to the sphere, it will produce a disk which has an diameter.

> Privileged ports in rootless mode not working? Good! That's security working as intended. A reverse proxy setup is a better architecture anyway.

So, how are you supposed to run the proxy inside the container? Traefik for example? Genuinely curious.

Re:AR Fluid Simulation Demo on Thursday September 04, 2025 @05:52AM (#45125453)
Virtually any LCD screen will produce polarized light. This is the core working principle of those screens. So if you use a polarized filter (sunglasses for example) it will completly block the image coming from the screen.

You can see the effect here: https://www.reddit.com/r/mildlyinteresting/comments/crvpil/t...

I believe this will not work with OLED screens though, but I do not have one to test this.

How exactly does this work? The example I chose is a mosaic of photos, over which is overlayed the original image with alpha set to 50%.

So it does not use the submitted photos as tiles, right?

Re:I hacked my washing machine on Monday July 28, 2025 @06:39AM (#44709387)
I believe that US 240V is 2 hots, neutral, and ground. EU 240V is one hot, one neutral and ground. EU 400V (380V) is 3 hots, neutral and ground.

None of this is cross-compatible.

Re:Wind Knitting Factory on Friday July 04, 2025 @05:43AM (#44462949)
To recycle plastic, the only viable way is to melt it. And the plastic must be very clean before it can be remelted. If it even is a kind of plastic that can be reheated multiple times. I am afraid the short answer is no.
Donated blood has a limited shelf life. So this is about the stocks the donation centers have. This tech can use the almost expired stocks to "recycle" the donations, instead of destroying it.
It looks like the decision has been reverted, for now at least: https://www.forbes.com/sites/kateoflahertyuk/2025/04/16/cve-...
Re:Bayesian Yacht Sinking on Friday November 01, 2024 @08:43AM (#42016400)
From skimming the article, it seems the boat sunk in about 2 minutes. While most of that time it was already laying on it's side.

This would make it virtually impossible to get out, if you were below deck.

Re:We're excited about our new roundabout on Monday October 07, 2024 @07:47AM (#41765054)
Yep, in my city we have a roundabout with 4 cardinal directions, roughly aligned with compass directions.

The West connection is to/from highway, so it has most traffic. People arriving from North/East/South want to leave on the West. And this causes massive jams, as the constant supply of traffic going from South entry to the West exit (i.e. doing left turn, and passing all ramps) essentially blocks all the other traffic.

Roundabout are great, they increase safety of dangerous intersections. But sometimes a controlled intersection is just a better idea.
