Please don't be sorry! I'm genuinely surprised that several people experience a different association with the acronym with relation to technology and open sourcing 'things' especially in the HN space. I grew up with CDs, however as I mentioned in another comment I haven't used or had the means to use optical media in over a decade nor do I see optical media present at work or with friends so it's quite interesting to me, I'm not convinced that I'm in some sort of 'bubble' but more that perhaps that it could be something like a generational association. If you don't mind me asking, in the name of science - what age bracket do you fall under? I'm 30 or there abouts and for me I think optical media became something irrelevant or perhaps irreverent in my technical / cultural experiences in around the time of 2006-2008 and continuous delivery / integration became a valuable focus of product delivery and technical engineering at around 2010 and something that I've been experienced since around 2011ish.

I'm genuinely surprised about this too. 5 minutes ago I would have been certain CD = "Continuous Delivery" with any group of developers, even more so HN. It makes me wonder what other assumptions I'm making or things I'm taking for granted.

I think you've hit something quite relevant here. While compact discs aren't something I deal with daily anymore, I've never been directly involved in continuous delivery. So I feel that it's because I haven't overwritten the acronym as of yet with a more relevant context.

I think it's just industry terminology for someone not in that exact space.

I'm 34 by the way.

I initially thought it was a story about some obscure compact disc pressing/inventory management system that Yahoo apparently had lying around because big corps have strange stuff in their basements. I mean, it's pretty common to see curiosity/historic articles on HN. 35 years of age ;-)

40ish. I still use DVDs almost every week: buying (mostly pre 2005) movies and rip them to my Plex for viewing.
