One more reminder that Slack is a terrible choice for communities, and extorts even nonprofits. Even when it’s one teaching teens to code, for free.

Hack Club is moving to Mattermost. They really have no choice.

Just a poor taste how Slack demands $50K in a week, no real notice

Picking colors for an overview in a ppt, how about white, pink, light blue? 🏳️‍🌈Who would notice? I’m sure @the-qa-guy.bsky.social would

No one told me the hardest thing about software engineering was compartmentalizing the state of the world so you can focus.
