GraalVM dive in Clojure at work


I looked into the state of GraalVM and Clojure and wrote some small work-related scripts.

Frequently I want to use reductions only to quickly realize that I'm not interested in the successive values of the state.

A simple example is to imagine one wants to increment a number represented by a sequence of its binary digits:

(inc '()) is (1)
(inc '(1)) is (0 1) ; yes the list is inversed, the lowest significant bit is the first item
(inc '(0 1)) is (1 1)

A few thoughts on Aleph development

Aleph, Async, HTTP, Clojure

I've been working with Aleph rougly for last 5 years, actively contributing to the library for last 2 (or so). I also put some effort into spreading the word about it, including educational tech talks, like "Deep HTTP Dive Throught Aleph & Netty". But the more I talk to people the more confusion I find, mostly about how Aleph works and what can you expect when adding it to your stack. Clojurists Together has recently announced Aleph to get Q1 funding, I think it's a good time to share my priorities and thoughts on development plans that were mentioned in the blog post. Hope the community would find it interesting and helpful.

Aleph describes itself as "asynchronous communication for Clojure" library. And you should probably pay a good portion of your attention to the first word: "asynchronous".

  • To allow such references to be queried and updated automatically.

Using `lein-tools-deps` from Cursive (on macOS)

Note: These workarounds covered issues in lein-tools-deps 0.3.0-SNAPSHOT. If using 0.4.1 or later, you should not encounter the issues below.

The following provides some workarounds for some issues when using lein-tools-deps from Cursive on macOS.

Path to clojure

By default, the lein-tools-deps plugin won't see /usr/local/bin/clojure when Cursive processes project.clj, as it evidently has a degenerate path.

You will see an error like the following in the IntelliJ Event Log when it tries to process your project.clj file:

You can’t perform that action at this time.
