This is the bi-weekly visible open thread. There are hidden threads every few days here. Post about anything you want, ask random questions, whatever. Also:

1. Google is saying that SSC has been hacked. Technical side has confirmed that it hasn’t been, so don’t worry. Still trying to figure out how to get Google to remove the warning.

2. User deluks917 has set up a Discord server for SSC. I don’t know whether people prefer the this or the IRC, so I’ll just let them fight it out and officially endorse whoever wins.

3. Some really excellent comments this week. From the perceptual control theory post: Null Hypothesis on their own experience as a control engineer (+Garrett), Controls Freak with a different perspective, a control-related perspective on obesity (but see here), and jasongreenlowe wins the thread. And from the antidepressants post: Mediocrates on plasma levels, Jacob on cancer genomics.

4. A new ad on the sidebar: Hi-Phi Nation, a philosophy podcast that describes itself as “bring[ing] philosophy out of stories of ordinary and extraordinary human experiences”
