Useful Life Live Lab
Forty units are on a burn-in rack right now, failing on an exponential clock. Your job: estimate how long the thing actually lasts, notice the moment its failure rate stops being constant, work out what changed, and prove your fix moved λ the way you meant it to. Plan on about 30 minutes.

It opens with your Cornell login. The lab lives on the course's own server, so signing in is how it knows who you are — there is no code and no password to type in. Each lab opens on the day we run it in class, so if you are looking ahead and it turns you away, that is expected — come back on the day. If it still turns you away during the session and you are on the roster, tell the instructor rather than hunting for a workaround.
