Ask HN: Self hosted user friendly chat app for family? about about 16 hours agoI maintain a Synapse homeserver for our open source project and it seems to work fine, I don't know how different it is from Conduit. Other open source and self-hosted chat apps I've heard of but haven't used are Mattermost and Rocket.chat.  https://mattermost.com/  https://www.rocket.chat/.

Spotlight no longer works about 3 days agoI have "Applications" selected in Spotlight preferences, but when I use it, it only comes up with everything but Applications. I want "slack" and get a link to "slack.com" instead. I've submitted feedback, but have not gotten any response. Anyone else have this problem? Years of muscle memory in my fingers gone to waste. I actually have to use the Dock now to get to apps I want. Ugh.
