Awful.
After coming into work an hour late (kind of a standard at this point), I spent the entire day under the gun to finish off the Client Build (read: closed beta) of our Alzheimer's app. It got until 9:30PM and I came within an inch of the app being finished, but I was held back because Local Device notifications, the most important and generally most reliable thing, weren't playing at all.
Was feeling pretty stuff walking back through the city and now I've had to change my shift to come in this morning and fix it.
