If they're running hardware that old, and it's causing them software compatibility problems, then we can infer that their infrastructure is unmaintained, because the cost of moving to newer hardware is so low that the cost of ne

Yes, a used laptop would be an upgrade from server hardware of that vintage, in performance and probably in reliability. If they're really using hardware that old, that is itself a big red flag that F-Droid's infrastructure is fra

It seems quite implausible that F-Droid is actually running on hardware that predates those instruction set extensions. They're seeing wider adoption by default these days precisely because hardware which doesn't support them is g

Far better would be to tweak the time constants to your liking, so that you can use the full clock range of the chip, but constrain its sustained power draw for quiet and long battery life.

The Type-C DP input appears to be using a DP to LVDS converter, so the FPGA is already accepting LVDS, it just doesn't expose a connector for it. But for interfacing with laptops, these days it's eDP that matters, not LVDS. So the

Intel's Arrow Lake platform launched in fall 2024 is the first to support CUDIMMs (clock redriver on each memory module) and as a result is the first desktop CPU to officially support 6400MT/s without overclocking (albeit only r

I think it's important to make a distinction between secure boot features that are local-only, and remote management features. The "Remote Device Management baked into firmware" claim above carries with it some pretty importa

The workloads that people care most about today that need high RAM capacity are workloads that also need very high memory bandwidth. Old server hardware from eBay doesn't do a good job of satisfying the bandwidth side of things.

Is that an x86 translation issue, or a graphics issue? The chips Qualcomm has shipped so far for ARM PCs have bad graphics hardware and worse drivers. And that's the best case, where the ARM system is at least running Windows and nomin
