Ruby Central said some really concerning things today. I don’t think they’re representing the situation accurately. andre.arko.net/2025/10/09/t...

The RubyGems “security incident”

Ruby Central posted an extremely concerning “Incident Response Timeline” today, in which they make a number of exaggerated or purely misleading claims. Here’s my effort to set the record straight. Fir...

Kasper Timm Hansen @kaspth.com · 12d

I also appreciate the feedback that even in the updated version on spinel.coop you don't find it to put the business case first. I'm also curious about that'd look going forward, so I'll keep that in mind. Thanks!

But now I feel bad that I didn't explicitly ask for your feedback on the site language back on Sep 1 when I asked for your feedback on our retainer proposals we'd been sending out so far.

Kasper Timm Hansen @kaspth.com · 12d

I saw the language as a placeholder as we're figuring things out for our version. Because ultimately we'll be talking to potential companies, and seeing what resonates with them and tweaking whatever the wording is on the page from that.

Kasper Timm Hansen @kaspth.com · 12d

Just a heads up from how I saw this. The language there was inspired by Geomys (as the first line mentions) and you can find the same wording geomys.org

We've been in talks with them and asking for advice on how they've set things up. They've been very kind and helpful imo.
