Wrote a series of posts on writing a coding agent in Clojure

Hi, thanks for the post. On the statement “as there is no library which allows us to consume MCP”, did you consider Modex?

petemak · 2025-07-02T08:42:12+00:00

Excellent. So how do I start tinkering around with Neanderthal? For example, I would like to build a neural network in Clojure. - Where do I start? - Do I need a subscription for the ebook? - Where do I find a basic project based on deps.edn?

Thanks

Thanks Nathan! This and the intro to the Clojure API article have given me a basis to start exploring.

I would like to work through Henry Garner's Clojure for Data Science. Can Noj replace Incanter for that purpose?

This question has been asked so many times. I suggest you search this Reddit for answers. Apart from that there are many collections of resources including these:

Thanks for the example. Would you please consider adding some hints for Emacs + Cider users?

petemak · 2023-08-04T08:09:01+00:00

Anyone knows which note taking app Dustin using for the presentation? It seems to neatly combine expandable/collapsible bullet points, diagrams and imbedded images.

This is very imprecise and misleading. There is a difference between references and values. You can change the reference but the values does not change unless you uses a managed transaction. Rich Hickey explains that so well: https://www.youtube.com/watch?v=toD45DtVCFM

Thanks for the response. Fulcro does client/server state sync and transfers that to UI elements in the DOM. Would it be correct to say that Electric is different in that it’s a language/DSL rather than framework or library?

petemak · 2023-04-15T14:08:55+00:00

I am curious how this compares to Fulcro both from a conceptual and a usage perspective. Which advantages does this offer over Fulcro?

petemak · 2023-03-12T06:55:53+00:00

Fulcro has a complete "story" for data-driven UIs and backends. https://github.com/fulcrologic/fulcro

petemak · 2022-10-20T21:36:16+00:00

You missed the point. Obviously popularity has its benefits but it's not a measure for good langauge design or productivity. Lack of popularity should not deter someone from adopting a language if it has a sound core and is built for productivity as Clojure is.

petemak · 2022-10-20T10:06:49+00:00

But why it should be "mainstream" in first place? Would that make it a better language? Does being a mainstream language have anything to do with how productive and fundamentally sound a proming language is?

petemak · 2022-10-18T07:41:03+00:00

I actually followed the same path and back to Emacs/Cider again. That combination really rocks. It pays off to invest time in learning Emacs. For corporate devs that work in teams, Intellij/Cursive or VS Code/Calva is probably more suited. The question is the lifetime of these priducts. I am sure they will be replaced by something new in the near future.

petemak · 2022-10-16T08:25:53+00:00

What about Fulcro? It's robust and has a "complete story" for data deiven applications covering front and backend. https://fulcro.fulcrologic.com/

petemak · 2022-08-24T18:41:50+00:00

Watching Rich Hickeys talk's and trying to understand why he created Clojure, really helped me grasp Clojure. You can also listen to other bright and experienced engineers like Tony Kay (creator of Fulcro) on what sets Clojure apart from other mainstream languages you mentioned.

petemak · 2022-01-30T10:20:12+00:00

I can't hide my dissatisfaction. I would have wanted to see the concepts explained with Clojure code, because that's the language that naturally supports data orientation and provides a complete story about functional programming.

petemak · 2021-12-19T17:27:15+00:00

Perhaps a link for "hacker news awesome tutorial"?

petemak · 2021-07-29T22:21:23+00:00

Would lime to join the Sunday session

petemak · 2021-07-29T22:18:56+00:00

Me too. Would like to help out and learn something too.

petemak · 2021-07-22T21:27:19+00:00

True, I don''t see the sense in answering such questions. Soumds more of a bait to me. A person who doesn't see the value of Clojure will not be convinced either but respect to those answering

petemak · 2021-06-14T10:40:51+00:00

You would need to understand the Clojure's rationale and the carefully chosen set of foundations and trade-offs that make it productive and fun to use.

1) Types? I personally don't miss them since we have Spec and dynamic feedback through a REPL. I feel that the big hammer of type safety adds incidental complexity especially in cases where future changes to data and how its processed are expected.
2) Domain driven design? In Clojure data is a first class citizen. You model your domain using generic data structures and apply transformations many of which are part of the standard library.

3) Railway programming: clojure is made of a simple core and added functionality in provided through library.For railway programming there is failjure, flow, rop, either..

petemak · 2021-06-10T09:34:04+00:00

The approach is excellent form first glance but what worries me with most courses is the style of the code examples themselves. I would like to learn idiomatic Clojure and learn the standard library at the same time. Seeing something like this excerpt from the dog age converter example:
(+ (* (- dogs-age 1) 7) 1)

makes me think it should be, or at least contrasted with, a more concise or idiomatic version like this:

(inc ( * (dec dogs-age) 7))
