HN discussion> but they could have been just as successful using another language. I remember reading about one founder that picked an obscure language because in doing so, it self-selected for more curious engineers who worked in the languages for fun rather than any other practical (re:job) reasons. His thesis is that finding one really good engineer in said language was 1 in 10 (10 interviews to find 1 really good engineer) w…

HN discussionAt JUXT we use Clojure's EDN, bolstered with some tag literals courtesy of our Aero library (described here: https://juxt.pro/blog/posts/aero.html ). We use ClojureScript to compile to TF's JSON. EDN allows comments, ignores commas and otherwise is a nicer JSON. Aero allows us to encode multiple environments in a single document, and include ciphertext for secrets. We're pretty happy with the overall result.

on “Terraforming 1Password”Submitted The Value of Bitemporality – Whose Time Is It Anyway? as a story · 91 points
HN discussionKind of a weird, cliche-informed rant here about lisp. To clarify, lisp simply offers functional programming by default and metalinguistic abstraction - most languages don't. So it tends to be used by people/organizations seeking higher-level organizational tools than functions/modules/classes or organizations looking to leverage functional paradigms. It's plenty stable and plenty dependable - just look at some of t…

HN discussionI think to be really useful an event sourcing data store needs `as at` support in addition to `as of` (i.e. bitemporality) to cope with retroactive and proactive events and corrections. There are a couple of references for this in the Crux docs: https://juxt.pro/crux/docs/bitemp.html#_known_uses

HN discussionWell, Eva overlaps very closely with Datomic so I would recommend taking a look at the FAQ entry I wrote on the Crux/Datomic comparison (with 8 sections covering the major differences!): https://juxt.pro/crux/docs/faq.html#_comparisons `EAV+T+added?` is the canonical data representation used by Eva, whereas Crux relies on two discrete "document" and transaction logs as the canonical representation. There are many re…

HN discussion> Lest you think is just one weird corner of the sql spec, I found this helpful diagram explaining how the scoping rules work (from Neumann and Leis, 2023) It's an excellent diagram, it really conveys the dissonance. Incidentally I interviewed Viktor Leis on a podcast last week about the paper where it's from: https://juxt.pro/blog/sane-query-languages-podcast/ A lot of people seem to believe that LLMs or other ML m…

HN discussion> Don’t expect much more growth out of this language in terms of new projects written in clojure. Why would an average dev not be able to maintain a clojure code base? I'm going to guess what you really mean is a average dev that doesn't know clojure. In which case the argument your really making is that its hard to find "clojure devs". Which I think runs contrary to the numbers which suggest many more people wantin…

HN discussionI agree the opportunity is still there, although the long game keeps getting longer. Prof. Viktor Leis suggested [0] that SQL itself - being so complex to implement and so ineffectively standardized - may be the biggest inhibitor to faster experimentation in the field of database startups. It's a shame there's no clear path to solving that problem directly. [0] https://www.juxt.pro/blog/sane-query-languages-podcast/
