This method of animated QR data transfer is quite efficient with fountain codes. I had PoC implementation back in the day - Txqr [1] [2]

Recently I rewrote it in Dart/Flutter and finally implemented RaptorQ codes (way more efficient than Luby used in original Txqr). Testing it internally now, prepareing Appstores/GooglePlay/Web deployment and new article.

There is definitely some body of research around what I'm asking [1] [2]. Just curious if someone have a good grasp on the current state of it.

Does anyone know if it's already possible to build gaussian splat of the person that moves/rotates from the single camera? (I.e. to use sequence of frames to reconstruct occluded parts of the body for other frames)

> Ostracization has worked before.

It also hasn't worked before.

Except of hope that it will decrease sales (which is still not solving privacy issue), can you see other possible negative effects of the ostracization based on the gadgets they use?

How does not talking to people will solve privacy problems of the new technology? Are you assuming that Meta will see that you ignored your coworker with smart glasses and shut down the project, along with Apple and other smart-glasses manufacturers? I'd love to follow your logic, if you can't follow mine.

Yeah, it's questionable that Davinci layout will yield a good photo experience, but it's interesting development anyway. BTW, that's the reason I like Photomator - it has absolute minimum of what I typically would use, and it's all there. Like, there is a hotkey for autoaligning horizont (and quite often it actually work), or intuitive AI-powered 'Select subject'/'Select background', and even an easy way to back those typical change into edit that can be applied with a hotkey onto a bunch of photos. It's easy to spot when software was written based on pain points of real end users.

You're not the first :)

If you know how to do masking with video in Davinci, then it all just applies to photos too. I tried today some basic Magic Mask and color tab editing with photos, and it works exactly the same (without the annoying waiting time on huge videos for Magic Mask, ofc).

Oh, I'm on subscription. Haven't seen those changes with pricing options, thanks. Subscription seems to be at the same price (even lower? it shows 14.99$ now, and I think I'm paying around 18 EUR/month with taxes).

While we're on topic, I've been using DaVinci with this camera for a slightly unusual hybrid process. With a good light and lens I shoot slow-mo video (240fps FullHD or 120fps 4K) with shutter speed of 1/1000. Then I can take any frame and save it as a photo directly from Davinci.

I wrote 2 scripts for that:

- first is for keyboard shortcut that automates "Switch to color tab, Grab a still, Save a still to folder, Switch back"

- second for more advanced workflow where I put markers on the frames I like, and then it uses Fusion's Saver node to save images as EXR

This flow is even faster than culling with Photo Mechanic. In both cases I get 10bit PNG or EXR images that I can import into the photo editor. Workflow is far from the perfect yet, as it might need some adjustment when working with Log profile or different FPS (for 2nd script).

But aside of giving me an option of "shooting" video+photos at the same time, it blows my mind that it's practically "shoot photos 240 times per second and choose later", and how good the end result is. The bitrate of video is 280Mbps (4:2:2, 10bit) and while video compression quality is not negligible, the resulting "still photos"'s quality is more than enough for social media purpose.

Cautiosly looking forward to it. I shoot with A9 III (global shutter camera that makes 120fps _RAW photos_), and dealing with thousands of photos per shoot is a challenge. I don't use Adobe products and still looking for a good stack for photos processing, but it's an uphill battle.

For culling there is nothing better than Photo Mechanic. Worth every penny. For editing, surprisingly, the best solution (performance/features wise) I found is Photomator (recently acquired by Apple). The trick though is not to import RAWs into Photomator, but import into Apple's photo library first (so it doesn't copy RAW files from SSD and doesn't not sync with gallery ofc), and Photomator picks it up natively.

Performance/features wise this stack works fine, but it's a constant juggling with 3 apps, which makes if far from perfect.

Curious to try DaVinci Photo and see how it handles large collections of RAWs and how practical it is to use.

Can someone quickly vibe code MacOS native app for that so it doesn't require running terminal commands and searching for that browser tab? (: (also for iOS, pls)

Thanks, tried it, but it's crashes on clicking the microphone icon. Default `make install` for some reason tries to install it to /usr, I changed that and after torturing more mature coding LLMs for 20 minutes, made it running with mic/sound.

The mic button requires clicking to transcribe and start listening again, and default voice is low-quality (I assume it can be configured).

In general I'm looking for a way to try the on-device hands-free voice mode.

Age verification doesn’t necessarily imply identification — eIDAS 2.0 and ISO 18013-5 have selective disclosure by design.

You can also create a skill for reviewing (which calls gemini/codex as a command line tool) and set instructions on how and when to use. Very flexible.
