One of the blogs I link to is the Blog of Helios, the blog of the HeliOS Project that puts computers running Linux in the hands of kids in the Austin TX area who would otherwise not have access to technology. The Project could use your help; consider donating your not-too-old gently-used hardware.
More urgently, though, Diane, the partner of Ken (who runs the project) is in need of help. She suffered a stroke due to an aneurysm, and the surgeons were going to go in and install stents... until it came up that she's uninsured. More details here.
