There is a free and open source app called SelfControl for macOS. It allows one to block access to any site one adds to the list in the app for the amount of time the user chooses. Attempt to use multiple browsers, restarting one's machine, deleting the app, etc. won't get around the block either. It's been super helpful for me, so I thought I'd just throw it out there. https://selfcontrolapp.com. - Source: Hacker News / 6 months ago

It is SelfControl. It is open-source and free. You select the website you want to block and the time. The moment you click the button no matter what you do, you can forget about accessing those websites until the time is over; there is no cancel button. Restarted mac won't work, you can delete the app no luck. Source: 7 months ago

The SelfControl app lets you specify web sites that will be blocked. When you run the app, you specify a countdown timer, during which time those apps will be inaccessible. Source: 7 months ago

Tools like Gather Town to encourage more ad hoc group interaction. One team I led used this tool daily for nearly a year, and the frequency and quality of our interactions were on par with an in-person office. - Source: dev.to / 10 months ago

I'm really digging gather.town for this. Our team has it set up & the ad-hoc "meetings" have gone up tremendously. You can choose to engage or not but it seems to be way more informal than slack for a quick sync, which is a gigantic strength imo. Source: over 1 year ago
