Same. Apparently there's ongoing work to integrate live traffic: https://codeberg.org/comaps/comaps/projects/21877

I struggle to find good resources on this topic. The few I found indeed attribute the lower latency of more recent Wi-Fi generations to techniques like MLA and OFDMA, not necessarily the frequency (which makes sense, of course). The cudy link makes it look like channel congestion is a factor, too. https://www.rtings.com/router/learn/research/wireless-latenc... https://www.zbtwifi.com/blogs/frontier-technology-news/wi-fi... https://www.cudy.com/en-benelux/blogs/news/6-ghz-vs-5-ghz-th...

While it already is a very deep discussion, like most it does not discuss the latency improvement that 6 GHz Wi-Fi brings. Afaik Wi-Fi 6E 6 GHz has a latency of 5 ms and less, while Wi-Fi 6 comes with about 10 ms at 5 GHz.

As usual, the Apple design is a great baseline: https://www.audiosciencereview.com/forum/index.php?threads/r...

It doesn't provide full volume output under Android, though.

Otherwise, the CS43131 DAC powers some great designs. I can't comment on their durability, though. https://www.audiosciencereview.com/forum/index.php?threads/j...

He regularly wrote essays for "Süddeutsche Zeitung", commenting on the world's political situation. The last one I read was published in November 2025. Sharp as a knive, as always. I'll miss them.

What an accomplished life.

I would guess so, as the BC-250 is basically a PS5 with 24 instead of 36 CUs. For the curious: https://github.com/mothenjoyer69/bc250-documentation I would guess that he could leverage the APU support that was merged with Mesa 25.1.

I second this, although since the Pixel 8(a) they all come with USB-C 3.2 and DisplayPort support. You have to buy a cable that supports it, though.

I'm on board as soon as they include a zoom camera.

But for now it seems like I'll remain with a Pixel and GrapheneOS.

Their last announcement is from November 2024: https://jolla.com/press

I guess they'll start PR once the phone is funded.

That threw me off, too. They probably chose it to keep the costs low. I wonder about the overall impact, though.
