Random stuff I consider worthy of sharing. Mostly tech.

In 2022 I wish all of us more of the open ecosystems, more of the free devices, more of sensible, sustainable decentralisation. I wish all of us meet with positive changes personally and around. Despite the enormous motivation required to make another TP real, I hope to come closer to that goal, even though it's not the most important matter that I have to face. Ironically or not, everything non-TP is influencing TP more than actual TP stuff. On TP1803, we finished proving that the idea is viable, that the right people can be brought into an initiative that makes sense. What's left is new contacts, organization, management and engineering burdens, money. To this date, it seems that most of this mission remains directly on me. I consider it as natural state of being, but that also means there's no ETA or deadline of any sort. Again, for me and all of you, I wish that I'll be able to follow up with the idea and bring some actual hardware sooner or later. It's possible, but can't be rushed.

Considering that even the most ridiculous stuff gets patented, it's not surprising, but I really hope that this idea won't get implemented in real world. Mechanical elements occupy exactly the place that can be directly used for a custom, square camera sensor, with smaller engineering requirements, smaller risk of fail and the advantage of complete multi-aspect shooting.

To be clear, rotational stabilisation is a good idea itself, but you don't have to exactly move the whole camera module to achieve it. Lenses are already round, but the sensors aren't covering the whole image area. Filling it is a quick fix with more benefits than rotational stabilisation of extreme angles. I expect multi-aspectness to be a trend some day on phone cameras.
Since the very beginning of Camera2 API and Camera HAL version 3 on Nexus 5, Android (and the newly introduced back-end) let apps (initially on just Google devices) to access raw camera stream at a fast rate. That time, I mostly looked up to manual controls in still photography, but as a matter of thought experiment, I also started to wonder how fast you could actually save the raw frames to device, especially seeing that utilizing the API already meant an experimental app succeeding with full sensor (4:3) recording. Through the years, the question of raw video performance remained unanswered, seemingly (for me back then) due expected ability of doing 1080p30 at best. That assumption was wrong. It seems that my thinking has been similar to devs who had the capacity of building such a proof of concept app. They either never built any or were indeed disappointed by performance, discarding the whole idea.
But they forgot about one thing that actually works and makes a mid-range device able to go over 1440p or even 4k: real-time compression. And that doesn't even count splitting the bandwidth to any external storage. It took 2021 to see the first app doing exactly that, Motion Camera. Have a phone with a sensible mobile lens, enough storage? You can get pretty awesome results that can't be reproduced even by professional-tier commercial apps. You can't get it even on 1k USD iPhone (damn, I'd want to know its raw burst rate for third party apps (BTW, ProRes isn't raw)), it all exists due to power of a small brave project that can utilize the advanced API we got. As can be expected in real world, there are devices where burst rate is broken, mostly by OEMs trying to do too much, but the vast majority of Snapdragon devices lets you access the constant 30 fps rate just fine. So if you're either interested in recording on the budget or on the go, or want to experiment with something new, the app awaits you on GitHub. :>
Enable the strongest raw compression, make sure you got enough space, keep the RAM buffer setting low if your RAM is low or badly managed, and with a sensible device get ready for very flexible results, that you can process as you want in DaVinci Resolve.

And as a matter of fact, Snapdragon 460, 662, 480, 680 and 695 have a pretty good chance of getting you more than 1080p60 if your storage speed is good. Why is that special? Well, ability of recording raw faster than a HEVC feels a bit counterintuitive, especially if you count in the status quo of the mobile and big camera market. Yes, these chips can't encode nor decode more than 1080p60, while lossless compression raw recording has a good chance of bypassing this limitation.
Been told the reference isn't very obvious: the pic above are Apple's words about Macs, the crossed out fragments are to point out the contrast of their attitude towards app sideloading on iPhones.
"realme 9 Pro+ is the first Pro+ product in the history of realme Number product line, equipped with Sony IMX766 OIS Camera, which can shoot flagship smartphone level high quality photos. It is equipped with realme's self-developed ProLight imaging technology, which can take clearer and purer nightscapes."

Aside of being wrong to conclude it on the basis of a single device, it's also completely wrong when coming to any recent (not ancient) production Qualcomm smartphone. Their VM implementation is way different and you can't casually get your kernel booted up in ARM EL2 mode.
I made a channel that simply tracks a few atom feeds of AOSP superproject branches. As it points to a Gitlab mirror, you can directly compare the difference between git refs, contrary to the original Google website. In the long run, it'll probably just make it a bit easier for me to find stuff through keywords right on Telegram. Some may find it useful too, so I'm linking: https://news.1rj.ru/str/AOSPrevs
"Just as we were ready to call the 50MP mode on the S22+ mostly unremarkable and write it off, Samsung's new Detail Enhancer feature managed to step in and change our opinion quite a bit. It is a feature making its debut on the S22 family and is available within the 50MP camera mode on the S22 and S22+ and the 108MP mode of the S22 Ultra. What it offers is a more sophisticated AI-driver picture stacking that combines multiple shots to resolve the most detail possible. We have to say the results are impressive. The extra detail is there as promised while also maintaining consistency in other quality aspects.

Detail Enhancer does take a few seconds to capture a shot. Not more than Night Mode, though, and its toggle is kind of easy to miss within the camera interface unless you know to look for it. Other than these minor issues, we can wholeheartedly recommend it for its results. If you are going to shoot in 50MP mode on the S22+ for the extra detail, you need this enabled."

I wish one of their humanitarian efforts would be letting their customers in a critical situation use their hw with no restrictions that can render it useless in case of an internet outage. Offline app sideloading can be crucial to keep local (off-the-grid) communication up.
