QEMU is always going to focus on emulation fidelity first and there are few shortcuts. With floating point the differences aren't generally in the numbers but in how the NaNs and other edge cases are handled. If you want to execute FP heavy code you should be cross compiling anyway.

QEMU absolutely will use hardware floating point where it can but only when it will give the correct results. FEX and Box64 are user mode emulators which achieve their speed by avoiding emulation where they can buy thunking at API boundaries.

They won't directly support it because in their view the Google Play process is a more secure way of verifying they supplied the binaries than is possible of f-droid. If reproducible builds were possible maybe there could be some mechanism to verify a given binary is built from a given commit of the source tree.

Other way around. Loyalty cards have always been about getting that sweet sweet data about customer habits.

Btrfs never really worked out for me (I think default COW doesn't play nice with VM images) and ext4 works great.

Pretty much. From v8.0 onwards all the extra features are indicated by id flags. Stuff that is relevant to kernel mode will generally be automatically handled by the kernel patching itself on booting up and in user space some libraries will select appropriately accelerated functions when the ISA extensions are probed. There are a bunch off advisory instructions encoded in the hint space that will be effectively NOPs on older hardware but will enhance execution if run on newer hardware.

If you want to play with newer instructions have a look at QEMUs "max" CPU.

Most solar inverters are tied to the grid so will be useless after the fall of civilization.

When did this change? AIUI creators got a larger cut of YouTube premium views compared to ad share.

I'm watching Voyager with my kids. Janeway is pretty bad ass given her position as the sole federation representative in the delta sector. We are however using a watchlist and skipping the filler episodes rather than going for the completionist approach.

My Organic maps has a download screen for the maps which regularly update outside of the app itself.

I think you underestimate how much storage those tiles take up compared to the vector map data.

The data updates are handled separately in app
