   A framework for building Slack bots in Python▲114

   I started building a couple of years ago because I found no easy existing solution to build Slack bots that can be composed from/organized into plugins. Existing libraries like Bolt make it pretty easy to develop Slack bots, but hard to organize and scale the code base of your bot. I was also missing some crucial features such as scheduling actions for your bot. So I wrote my own framework! I recently rewrote the complete framework to make use of asyncio and the newest Slack SDK Let me know what you think!

    We built an open-source alternative to expensive pair programming apps▲39

    My friend and I grew frustrated with the high cost of existing pair programming tools, and of course of grainy screens when we used Huddle or similar tools. We believe core developer collaboration shouldn't be locked behind an expensive subscription. So for the past year we spent our nights and weekend building Hopp, an open-source alternative. We would love your feedback and we are here to answer any and all questions.

Here's a quick demo: https://www.youtube.com/watch?v=wp1hoSCEArg As a heavy Notion user, I often found it tough to get my teams fully onboard since people naturally gravitate toward chat for quick interactions. Maintaining context between chat apps like Slack and documentation apps like Notion became increasingly…
