Sanjit discovered that the Gur1 channels are all digital 0. We determined that this began on July8, 04:00 UTC (~9pm on the 7th?).
It's digital zero, so we suspect a software thing. Just to check, we put a sine wave in, and didn't see anything. Gur2 seems totally fine, and the sine wave input showed up nicely on dataviewer. What's going on? Sabotage to prevent this paper from getting done? Dmass trying to get his paper done before me???
Investigations are ongoing.... Joe claims it's not his fault, since his shenanigans near the PEM rack were on days before, and days after this, but not on the 7th.
I just rebooted c0dcu1, which didn't help anything. Joe said he'd try to give me a hand tomorrow.
