Storing Image Data for offline web application (client-side storage database)
...che.
For storage I prefer use Indexed DB (support blob), Web SQL (only base64), FileWriter (support blob, but only chrome). Frankly storage is big issue for this. You need the fastest key value solution that will mix them all. I think is good decision to use exist solution.
For fetching I used canva...

How does C compute sin() and other math functions?
..., this is the code that actually runs when you call sin() on a typical x86-64 Linux system. It is apparently faster than the fsin assembly instruction. Source code: sysdeps/ieee754/dbl-64/s_sin.c, look for __sin (double x).
This code is very complex. No one software algorithm is as fast as possible...

Android emulator and virtualbox cannot run at same time
...yker, what the answer says is that emulators that run with CPU/ABI x86/x86_64 is a lot faster, but uses the same KVM (Kernel-based Virtual Machine) as VitualBox. Creating an emulator with another CPU, like arm64, will not conflict with VirtualBox, but emulator is a lot slower.
