HN discussionIf you take a language parser and pipe the resulting AST into Noms, you basically get something like codeq ( http://blog.datomic.com/2012/10/codeq.html ).

HN discussion> If you have 10s or 100s of app servers that has the exact same working set in memory, it's probably not worth it. The introduction of intelligent application-level partitioning [1] and routing schemes can help one balance cost and performance. [1] https://blog.datomic.com/2023/04/implicit-partitions.html

HN discussionThis reminds me of codeq, a clojure+datomic project that intended to move source control from lines of text to functions and expressions. From their introduction [0]: Backstory Programmer Sally: "So, what are you going to do today Bob?" Programmer Bob: "I'm not happy with the file baz.clj residing in my/ns. So I'm going to go to line 96 and change 2 to 42. I've been thinking about deleting line 124. If I have time,…

HN discussionSourcegraph folk, are you aware of Rich Hickey's codeq [0][1] for clojure: codeq allows you to track change at the program unit level (e.g. function and method definitions) and query your programs and libraries declaratively, with the same cognitive units and names you use while programming [0] http://blog.datomic.com/2012/10/codeq.html [1] https://github.com/Datomic/codeq#codeq

HN discussionExcision removes the data. In other words, you can remember that you forgot, but you can't remember what you forgot. http://blog.datomic.com/2013/05/excision.html What you're describing is plain ol retraction. If you retract your credit card number, then someone can just surf back in time to grab it. That's why you'd excise it.

HN discussionDatomic offers excision to cover cases like these (or other common cases where you are required by law to forget things). http://blog.datomic.com/2013/05/excision.html Note that even in this case, you can remember that you decided to forget, as a key premise of Datomic is that you always know how and why you came to record (or forget) a fact.

HN discussionWow, very cool indeed. We worked on an open-source community[1] tool using Datomic/Codeq[2], and the ops portion was/has been pretty unpleasant. I'd love to see Datomic-as-a-Service popup, even as a only-meant-for-starter-projects, just so that experimenting with it could be that much easier. That might be possible with the new license, depending on how the Cognitect team sees it. [1] The service is a frontend to Co…

HN discussionYeah, it kinda sucks -- mostly one learns to create new copies of definitions/code when doing substantial changes, which the notebook interface makes quite convenient. Or use a full blown editor like Eclipse. The holy grail as I see it would be storing the entire edit history of the document as a git-like tree of modifications, which is entirely possible because Mathematica notebooks are themselves built out of Math…
