Coloso Design Jun 2026

Coloso doesn't try to be everything to everyone. Their brand identity leans heavily into "premium." The UI is dark-mode centric with high-contrast typography, which makes the vibrant artwork in the course thumbnails pop. It respects the art being taught by getting out of the way.

🎛 Most education sites use generic stock photos or talking-head shots. Coloso uses high-quality renders and final outputs. It tells the user immediately: "You can make this ." coloso design

📱 The mobile app is surprisingly clean. No clutter. The video player controls are intuitive, and the "Class Note" feature is seamlessly integrated without pausing playback. Coloso doesn't try to be everything to everyone

Scaling Mastodon

My instance mastodon.social has recently surpassed 43,000 users. I have closed registrations both to have more time to investigate the infrastructure and ensure a good experience for existing users, and to encourage more decentralization in the network (with a wonderful effect — the Mastodon fediverse now hosts over 161,000 people spread out over more than 500 independent instances!) But providing a smooth and swift service to 43,000 users takes some doing, and as some of the other instances are approaching large sizes themselves, it is a good time to share the tips & tricks I learned from doing it.

Two reasons why organizations should switch to self-hosting social media

My name is Eugen Rochko and I’m the creator of Mastodon, a free, open-source federated social network server. The flagship instance mastodon.social has over 23,000 users and is growing fast. You can check it out here. If your organization is hosting a Mastodon instance, it is essentially a self-perpetuating brand awareness campaign. When people from other instances talk to or follow your users, they see your domain name all the time, since it is part of their globally unique usernames. It’s like those sticker ads on cars, except you don’t have to pay for them and it doesn’t disturb anyone because you’re providing a service.
