Yesterday, the International Space Station made contact with Artemis II, marking the first time in history that two spacecraft on separate missions communicated directly with one another. A first not just for space travel, but for humanity. Incredible. www.scientificamerican.com/article/in-a...

Been putting off moving off asdf to mise for managing Ruby versions for months. I shouldn't have. It took two minutes to migrate and it Just Works™.
Wondering if this is more or less likely to be true now. Might depend on definition of a SaaS.
Just found the video floating around, but didn't see it posted here yet. Here's hoping there'll be a next time :-). @friendlyrb.com www.youtube.com/watch?v=bUjV...

Hey Ruby consultants, freelancers, and agencies! Quick reminder: we have the Ruby Consultants Quarterly Gathering (over Zoom) on Monday, 1pm ET! Come talk shop with other Rubyists. (It's not widely publicized, so if you don't have an invite, DM me and I'll add you.)
Great short post from @mheap.dev: michaelheap.com/visibility-i... It takes practice to deliver the right level of abstraction--too many details are not great. But surprises are so so bad. Even if Alice delivers a month later than Bob, people understand why and are more likely to accept it.
