Hi, Russ, I feel better after reading your mail :) That's the way I modeled and still model things in my (long...) developer life, so I felt a bit strange after reading that discussion ciao giorgio On Fri, Apr 16, 2021 at 3:45 PM Russ Whaley wrote: > Wow, I must be missing a whole lot of context in that discussion... > (instant reaction as well, lol) > > - a product (CD, book, etc.) does not 'buy' - it can be bought, sure, but > it has no buying action.

Hi Tim, all, Weirdly enough, it seems my earlier reply to this thread hasn't been properly received/distributed by the list. Marcus was very kind to help me solve this, so you should receive this message now. Anyway... see my original message below. Hope it's still useful. - Hi Tim, Didn't really notice this thread until now. I understand you're looking into deployment using Docker. However, to provide some perspective, we're happily running Pharo in production on a (self-managed) VPS on Hetzner Cloud (which uses 100% green energy!). We use our own adaptation of Pharo server tools based on Sven's original work: https://github.com/objectguild/pharo-server-tools. We started with running Pharo 7.0 and have since upgraded to Pharo 8.0. Some experience with Linux command line is certainly welcome, but it should be fairly easy to get this going. Mind you, the README is (unfortunately) _not_ up to date. Regarding Docker, I don't have much experience myself. I've only used it a couple of times to troubleshoot smalltalkCI issues, never for running a Pharo server application. Hope this is of some use to you or others. Good luck and have fun! - Best, Jonathan van Alteren Founding Member | Object Guild B.V.

[Pharo-users] Re: Whats the easiest/cheapest way to run a Pharo web app in 2021?
Thanks for the details. I think that with the one from Norbert, you and me[1], there are at least 3 static site generators made with Pharo (and there was an old one, but I don't remember its name and I think is unmaintained). I wonder if there is some kind of Awesome Pharo alike list, to start adding them to a known place. There is the Pharo Documentation Wiki[2], but I kind of remember a longer more detailed list. Ummm... now I wonder if we could list a kind of decentralized list of "Powered by Pharo" projects taken from our personal, community or enterprise web sites. We may agree on using some kind of tags in the metadata to recover such distributed catalogue of projects. Certainly in my (incomplete) recent portfolio[3], Pharo has been a constant, in visible and invisible ways.
