It is my understanding that once an app has access to full X11, it can do everything you can do with your keyboard and mouse[1]. Like open terminals, cat files, it won't even have to parse the result from the screen if xsel or a text e

I now noticed that the NCR18650B batteries are Li-ion batteries (i.e. 2.7-3.7V range for one cell; I was thinking NiMH which are below 1.5V per cell). This may be harder to regulate to 3.3V as you can't simply choose a step-up nor step

That would need either a hook to the kernel or a file system parser. Even if you manage to do that, I'm not sure it would be a good idea to continue to use a file system that has lost sectors, even after fsck. Are you sure fsck is fixi

Yes, you're right, I made a jump in my thinking; I wanted to make the point that you could exclude the storage for the paths from the working set size, if there is only rarely a match. Problem is we don't have a number for the wor
