a practical one for today: lots of printers these days are so helpful with their ink monitoring capabilities that supposedly tell you exactly how many pages your ink tanks have left in them. it may just be that the pages that are being estimated have more written on them than the ones that i print out, but the cynic in me says that the ink manufacturers are just trying to sell more ink, and here's why i say that: my printer said it had
zero pages left in it about 20 pages ago, and it's still going strong. i bought a new ink cartridge weeks ago, when my black ink cartridge was "half full," just in case, but i'll keep the one i have in there until my printouts look different. my eyes are a better judge of when my printer is out of ink than a window on my computer screen is.
tune in tomorrow.
