Clojure itself actually loads pretty quickly, but almost every project has enough libraries to make loading the project take a few seconds.

This looks promising, but it doesn't work on personal accounts. I'm not ready to install it on my organization account just yet. Can I expect complex caching actions like https://github.com/DeterminateSystems/

Clarification on file duplication: DVC tries to use reflinks if the filesystem supports it, and falls back on copying the files. It can be configured to use hardlinks instead for filesystems like ext4 [0]. This improves performance signific

DVC is slow because it stores and writes data twice, and the default of dozens of concurrent downloads causes resource starvation. They finally improved uploads in 3.0, but downloads and storage are still much worse than a simple "aws

Performance with Docker is slightly worse, but it shouldn't be an issue for a long-running process. The main problem I've run into is that, by default, Docker logs will eventually fill the disk and crash the server. You have to ch

malli, specter, and calva are all less than ten years old. Clojure has seen a lot of progress in tooling and libraries.

Have you had problems with Nix on macOS? Nix works great for me, but I can't use it much to deal with installs or synchronize dependencies because the devs on macOS can't get Nix running.

I have no affiliation, but I tried the free trial of their tool and I found that the Code Health metrics made a lot of sense. The files that it pointed out are definitely overly complex and more difficult to change than they need to be. But

In production, I may only want one connection pool to a DB, and in that case global state is pretty much equivalent to passing state as an argument. Development in a Clojure REPL is a different story. I have one connection pool for the dev

Thanks for the explanation. What are some of the other techniques?

I just added a test case that importing org.apache.logging.log4j.core.lookup.JndiLookup throws a ClassNotFoundException. Any log4j2 class would work too.

Clojure is strongly typed and dynamically typed, not "untyped". Much of its core behavior is built on interfaces like ISeq. It's not uncommon to use a spec library like clojure.spec or malli, whose benefits overlap those of s

This is a good example of why dynamic vars are dangerous. They are just as perilous as global state, but are more surprising and more difficult to understand. Prefer passing explicit arguments in all cases. You don't have to even think

You might be just fine adding an unindexed tsvector column, since you've already filtered down the results. The GIN indexes for FTS don't really work in conjunction with other indices, which is why https://github.com&#x
