I run into a lot of tools that are either over my head, or beyond my frame of reference.
For example, yacpi.
As you can see — and as you might see even better if you visit the home page — yacpi shows acpi information (battery, AC adapter, thermal zones, etc.) for the host machine.
Or it would, if I weren’t using such an old computer, I suppose. yacpi works great on a newer machine, as you can see.
And is actually quite useful, in an oblique and monitoring fashion. As far as I can tell, beyond showing information like that you see above, yacpi doesn’t control, tweak, adjust or mangle anything on your system.
Apparently, it’s just got to be a slightly newer system. Than this one, anyways. 🙂
