If you end up blogging about CL (and tech in general) at Feetr, know that there will be at least one interested reader :)
It's something that I'd love to do, especially as there aren't many people using it in production, or at least talking about it, and I think that showing people it's a viable language could be important.
It's a shame that we as a community still throw around the Grammarly article as proof of people using it, I wish we had more recent examples.
Also, now that I've decided to go solo-entrepreneur, there is no one that can laugh at me if I decide to use CL for a core system.
Looking forward to reading your blog.
Especially in finance where most of the effort is geared towards data and data manipulation, it's almost a super power being able to work with live data and live systems. Your development speed is going to 10x.
I wish you all the best on your journey! Can't wait to see what you come up with!
CCL is used locally for two reasons 1) error messages are better and 2) it ensures that we're writing portable code. SBCL is used in production because it's much faster and it's constantly being updated, so we get cool things for free. I have been eyeing lispworks but I don't know that it offers much benefit right now. We do plan on mobile apps at some point and that's a conversation we'll have with them.
Production itself is pretty much just a live image, not much different than what you'd have when you're developing. We use slynk to be able to connect to it and play with the data. Can see that here [0].
GC hasn't caused an issue yet. I imagine we will run into issues latter half of this year when we roll out alerts but those are challenges which can be overcome. That might even be a lispworks thing honestly.
