How are you able to boot Debian from an SD card, and without unlocking the bootloader?

Does the bootloader look for an OS on SD card by default? SD and eMMC are basically the same thing, is it just the same lines but an SD card takes priority over the eMMC? And does it not enforce verified boot properly / at all? Maybe being a Rockchip and not MTK/QCOM has something to do with it, but it’s still an Android device and I would assume there’s something in CTS/VTS/GMS licensing that makes verified boot mandatory.

EDIT: A quick Google shows it's a pretty popular term, so I guess that's how I even know about it, the only other mechanical keyboard term in my vocabulary being "Cherry MX Blue clicky switches" for the ones on my AliExpress mechanical keyboard that prevent me from using the keyboard around other people. Unfortunately it also makes it difficult to hear the keyboard sounds without clicking on the letters instead :(

And yes even without the reference it's not that there's a literal animal there.

> As much mud in the streets, as if the waters had but newly retired from the face of the earth, and it would not be wonderful to meet a Megalosaurus, forty feet long or so, waddling like an elephantine lizard up Holborn Hill.

Why does “as if the waters had but newly retired” mean there’s a lot of water (and thus mud)? “As much mud as” clued me in, but I don’t get this part.

And apparently it’s also referencing not just some flood but the flood of Noah’s Ark from the Bible, which is why you might happen to see a dinosaur because it was such a long time ago. I guess I don’t come across many opportunities to think of / that remind me of Noah’s Ark because I didn’t think of that either.

Edit: I see another green comment was flagged for AI, might be indicative of something, but why so many green comments on this thread specifically?

Unifi released the UCG-Fiber around a year ago that can also apparently finally handle it, but plenty of threads about slow performance with their UDMs since it's entirely done on the CPU [0].

I'm not the biggest fan of OpenWRT and would prefer something like OPNSense, but it's x86 only and good PPPoE performance isn't guaranteed either - need a CPU with good single core performance that costs more than the BPI-R4, or apparently virtualizing OPNSense allows it to process PPPoE with multiple threads.

> Lenovo tells us, “The biggest challenge in getting to a 10/10 was balancing repairability with all the other expectations of a commercial device: performance, reliability, thermal efficiency, form factor, and design integrity. Repairability isn’t achieved by a single change: it requires many small, intentional decisions across the entire system, and each of those decisions can introduce trade-offs.
