dumdumdumdumon Vaccum-chamber quantum sensor device could allow GPS-free navigation

> Using a starting point as a fixed reference and calibrated to the patterns of Earth’s magnetic field, data from a quantum navigation system will give us all the information we need to accurately determine where we are.

Why is the Earth's magnetic field important? And isn't that just as easy to "spoof" (if not more) than a GPS signal?

dumdumdumdumon Inflation is wiping out wage increases for many workers

This just tells me spending increases. Nothing about absolute consumption. I don't know about others, but I'm consuming about the same amount of milk I was when I was getting $10/hr vs $35/hr. I might buy more "luxury" products (ice cream, organic milk, etc), but I'm certainly not buying more than I was at $10/hr. My caloric intake is about the same. Perhaps, I'm the odd one out. In my case, most of that extra money just went towards rent and a car.

But the rich do control the supply for everyday items. People aren't eating more all of a sudden.

dumdumdumdumon Show HN: I built a sonar into my surfboard

Do sharks (or other sea predators) respond to sonar? Is this more likely to make you prey or would it actually help with annoying them away?

dumdumdumdumon Twitch source code and customer data has reportedly been leaked

4.1k repositories!? Are these all Twitch originals or also some forks of public projects?

dumdumdumdumon DMV approves Cruise and Waymo for commercial service in parts of Bay Area

> Who is liable when someone gets hit with a self driving car?

As is usually the case with the legal system, whoever has the least amount of political/economic power. So either the safety driver or the victim.

dumdumdumdumon France Recalls Its Ambassadors to the U.S. and Australia over a Submarine Deal

A little part of me was hoping the objection was on the grounds that we shouldn't be increasing the number of hot nuclear weapons, but of-course it's just a turf war.

dumdumdumdumon Show HN: Blur Webcam Background on Linux

That's good news, but I'm kinda stuck using the web interface because the desktop client doesn't allow sharing single Wayland windows in presentation mode. Unless they've changed that too recently?

Nope, no GPU yet :(

Right now SelfieSegmentation is just a thin wrapper around the selfie segmentation solution provided in https://google.github.io/mediapipe. It operates on RGB frames, so that's why I need the conversion. The model inference is also done on the CPU. Interestingly, there is a GPU mediapipe graph available, but I haven't looked into what's needed to use that yet.

And yes, Boxfilter is just a wrapper around opencv's boxfilter. This is probably the lowest hanging fruit that could be moved to use GPU.

Not on Firefox though for some reason. Is there some special API only Chrome implements?

dumdumdumdumon Show HN: Blur Webcam Background on Linux

Yeah, this script will also heat your home :)

Especially, if you use the Zoom desktop client. Zoom on web (Firefox) seems to be easier on the CPU for some reason though.

dumdumdumdumon Show HN: Blur Webcam Background on Linux

Needed to blur the clutter behind me for meetings. Zoom and Google Meets don't support that on Linux. Couldn't find any existing solution that would give me a decent frame-rate for HD resolution without lagging. Wrote this instead.

Relies heavily on GStreamer under the hood for the video processing bits. And mediapipe for the selfie segmentation bit. Obviously need v4l2loopback to emulate a webcam. It's functional, but feedback and contributions are welcome :)
