I've been working in Clojure now for about 12 years. Maybe 12+ years of Java prior to that. I've created some great apps, and great libraries (in both Clojure and Java). I often de…

The cli/deps.edn tooling is different from Leiningen, and far, far less complicated IMO. I've written a good number of Leiningen plugins and it was always brutal to get anything to…

It's based on unification, like a Prolog. It does backtracking, like a Prolog. It has something akin to Prolog "cuts". It's equally not Markdown. What it is, is the sensibilities o…

That was my frustration as well; and it comes up in discussions. Simple to medium complex things are easy in Inform7, but when you start hitting the edges, you find out that its ex…

So close to describing the Dialog IF language it’s almost prescient. https://linusakesson.net/dialog/index.php Dialog is a Prolog dialect: it’s like Markdown and Prolog had a baby.…

I’ve been building some friendly CLI and web tools around the terrific Dialog interactive fiction language. https://github.com/hlship/dialog-tool Learning Svelte for the web UI par…

Clojure's slow, deliberate development pace confuses people. The core team takes backwards compatibility very seriously. What you see with each new Clojure release is generally imp…

Nubank purchased Cognitect (the consulting company behind Clojure) in 2020, as well as Platformatec (employers of Jose Valim); the latter was for access to Platformatec's project m…

In traditional databases, only the database engine has a scalable view of the data - that’s why you send SQL to it and stream back the response data set. With Datomic, the peer has…

A question for HN: I'm in the habit of making small changes, as I see them, in code - usually fixing documentation strings and comments, occasionally refactoring code or even addin…

It's actually quite a bit more than REBL; the description downplays something quite significant ... it can run as a client against a running Clojure in a separate process. Although…

That's not a very helpful, or accurate, comment.

Babashka has unlocked so much power for me. Clojure and the JVM simply aren't set up for rapid start up, Babashka is instant. Bash scripting is alien, ugly, and hazard prone for me…

In such a system, how does a reader find the root node? I'd be concerned about a) readers seeing a partial write to disk (or page buffer) during an update or b) a crash while the w…

We had drying issues with our Miele that was addressed by using the rinse agent. Now generally dry results.

Yes, and it caches results on the file system, so results persist between executions AFAIK. That comes in handy for one of my notebooks that has to slurp up Splunk data for 20 minu…

I've been using Clerk quite a bit lately and found it quite useful. Although I'm normally in a REPL loop, having control over the output ends up being very useful, and the ability …

Reverse engineering: Some of the things that Clojure generates are valid bytecode for which there is no Java source code equivalent. Reusing the pieces: In general, Clojure works s…

Although it is true that "time traveling" queries are relatively rare for production needs, the basic architecture supports things that many applications really need: - It is possi…

That would be very ugly source, as Datomic is written in Clojure and AOT compiled to Java bytecode. Due to the architecture of Clojure (especially, the use of macros) it is not exa…

In a traditional database such as Postgres, queries are routed through a database server that handles both queries and updates, and is quite close to the storage. Reading excess da…

It’s quite apples and oranges.

Like any database, Datomic often needs to perform queries by reading data from its indexes. In fact, in Datomic, all data is stored in indexes - there aren't rows with indexes poin…
