I wrote redb (https://github.com/cberner/redb) using mmap, initially. However, I later removed it and switched to read()/write() with my own user space cache. I'm sure it's not as good as the OS page cache, but the difference was only 1.2-1.5x performance on the benchmarks I cared about, and the cache is less than 500 lines of code.
Also, by removing mmap() I was able to remove all the unsafe code associated with it, so now redb is memory-safe.

I ran the benchmarks with SIMD disabled. Encoding goes from ~950Mbit/s down to ~350Mbit/s

Yep, we've been using GPUs for quite a while (even before the alpha support in Kube), both the K80s in Azure and some Pascals in our own clusters. With the support in Kube now it's quite seamless.

Still early in development, but I've been working on an autopilot for quadcopters that uses Python, and the ROS framework.

Ya, I'll add that to our list of feature requests. Would definitely like to put some more features in, to help people with blog posts or other research in the car space.
Ah yes, I would seem that green cars are going out of fashion, dunno who would want a purple car =P
