Dragan Djuric

2025 Annual Funding Report 5. Published November 9, 2025.

My goal with this funding in 2025 is to support Apple silicon (M cpus) in Neanderthal (and other Uncomplicate libraries where that makes sense and where it’s possible).

Having a decent Apple CPU engine for Neanderthal and a BNNS-based CPU engine for Deep Diamond completed in the previous periods, my main focus was on improving things achieved in the previous periods to support features and fix bugs that discovered while working on Clojure ML (diamond-onnxrt), the other major project funded by CT.

The first milestone for THIS project is that I supproted Intel’s DNNL (the Deep Diamond’s CPU backend) on Apple’s MacOS (both arm64 and older intel based). Due to Deep Diamond’s flexible design, this required only small changes to DD code, while the main issue was enabling and testing that architecture in the build of upstream libraries.

Several other areas fixed/improved throughout Uncomplicate libraries during this period include:

• Upgrading CUDA to the major new version 13.0, including improvements in code
• Working with upstream libraries on improving support for functionality that we need in Clojure/Uncomplicate
• Improving the UX of the distribution of dependency artifacts for CUDA and other dependencies that we use.
• Upgrading DNNL to 3.9.2
• Enable standalone activations, and other small changes to make sure DD accomodate onnx models inside DD network machinery
• Assorted improvements in supported types
• Helped in enabling CoreML in upstream onnxruntime build on MacOS

I released several new versions of Uncomplicate libraries with these user-facing improvements including:

• Deep Diamond
• Neanderthal
• ClojureCUDA
• Commons

Hammock time. Researched available native libraries that we can integrate next into Clojure ecosystem, including Nvidia’r TensorRT and Triton, Intel’s OpenVino, and similar AI-related stuff.

I wrote two tutorials and published them on dragan.rocks blog. They were received quite favorably, and it seems to me that Clojure programmers are quite eager to learn how to apply the stuff I’ve worked on.

2025 Annual Funding Report 5. Published November 10, 2025.

In these last 2 months I mainly focused on ECA development and related projects and improvements along with my Clojure Conj talk that’s coming this week, excited for it!

eca

ECA (Editor Code Assistant) is a OpenSource, free, standardized server written in Clojure to make any editor have AI features like Cursor, Continue, Claude and others.
There were so many releases and changes to ECA making it way more stable, with new features and fixing lots of bugs, especially with way more people using it daily and contributing!

0.44.0 - 0.78.1

Most important changes:

• Hooks support: This makes ECA one of the few opensource public tools with high customizable hooks support, hooks allow users to react to certain events like pre or post request or tool call.
• Rewrite: A new brand feature allowing to select a code and tell LLM to do something.
• Completion (alpha): First big step to allow completion, requiring only improvements in LLM output quality via model/prompt tunning.
• Plan behavior: Hugely improve plan behavior, making ECA one of the best tools for planning code changes, really a key feature of ECA.
• Clojure MCP integration: ECA is extensible so we can make it behave differently for MCPs, and we did for clojureMCP with Bruce’s help, making ECA show diffs beautifully before they actually happen.
• Contexts improvements: better context management via user/system prompts with options to unwrap files or just mention, making more token effective/controllable.
• More providers: Support google and more providers via more API improvements, making ECA compatible with most models at market and local.
• Native tool improving: Improved lots of ECA tools, based on tests and user feedback, making way more assertive and precise.
• Metrics via Opentelemetry: If you wanna take metrics of prompts and tools, ECA supports that now, really useful for companies that wanna track LLM usage.

And many more, check all changes below:

• Fix regression: completion broken after rewrite feature API changes.
• Prefix tool name with server to LLM: __. #196

Updates

The summer heat has faded, and autumn is upon us. One big focus for me is preparing my talk for Clojure Conj 2025, titled “Making tools developers actually use”. I did a test run of the talk at the Dutch Clojure Meetup. It went a bit too long at 45 minutes, so I have to shrink it almost by half for the Conj. The more I work on the talk the more ideas come up, so it’s challenging!

Presentation at Dutch Clojure meetup in October 2025.

Of course I spent a ton of time on OSS the past two months as well. Some special mentions:

• I’m pretty excited by Eucalypt, a remake of Reagent for Squint without React by Chris McCormick. It lets you build UIs with the Reagent API in less than 10kb of gzip’ed JS. The code was initially generated by an LLM, but now work is going into making the code base thoroughly tested and simplified where possible.
• After studying Eucalypt’s code I figured that making an even more minimal Reagent-like by hand would be fun. This is where I came up with Reagami. The API looks like a hybrid between Reagent and Replicant. You can build apps with Reagami starting around 5kb gzip’ed.
• Edamame got Clojure CLR support thanks to Ambrose Bonnaire-Sergeant.
• SCI Clojure CLR support is underway. The sci.impl.Reflector code, based on clojure.lang.Reflector was ported to Clojure with the purpose that it would then be easier to translate to Clojure CLR.
• Cljdoc chose squint for its small bundle sizes and easy migration off of TypeScript towards CLJS
• Via work on Squint, I found a way to optimize str in ClojureScript (worst case 4x, best case 200x)

Other projects

These are (some of the) other projects I’m involved with but little to no activity happened in the past month.

Oleksandr Yakushev

2025 Annual Funding Report 5. Published November 5 , 2025.

Hello friends! Here’s my update on September-October 2025 Clojurists Together work. I was mostly focused on CIDER-related work during these months.

nREPL

nREPL has received 1.5.0 and 1.5.1 updates which improve the reliability of load-file middleware and enable further improvements to CIDER debugger (mentioned below).

• #393: Add forward-system-output op for forwarding System/out and System/err output to the client.
• #386: Add support for XDG_CONFIG_HOME.
• #385: Preserve filename in functions compiled during regular eval.

CIDER

We shipped CIDER 1.20 which includes several highly-requested features and fixes.

• Debugger tags like #dbg are correctly processed when the whole buffer is compiled with C-c C-k (cider-nrepl#951)
• Tidy namespaced keywords in the inspector (orchard#354)
• Miscellaneous fixes and improvements to inspector and source file resolution.

CIDER-adjacent libraries

• Released orchard 0.37.0 and 0.37.1.
• Released cider-nrepl 0.58.0.
• Released compliment 0.7.1 (improved handling of namespace aliases)

JDK25 release support

As it happens semi-anually, the release of new JDK prompts ensuring that the libraries and tools are compatible with the newest version.

• Added JDK25 image to docker-clojure.
• Added JDK25 support to virgil 0.5.0.
• Updated CI pipelines to test against JDK25 in all CIDER libraries and all clojure-goes-fast.com tools.

Open source update

A big thanks to Clojurists Together, Nubank, and other sponsors of my open source work! I realise that it’s a tough time for a lot of folks and businesses lately, and that sponsorships aren’t always easy 🙏
- Peter Taoussanis

Hi everyone, hope you’ve all been well! 👋 Almost the end of another year, unbelievable 🫣 Note that some releases ran a bit late this period so were actually published in November, but I’m including them here since they’re part of my Sep-Oct tasks.

Recent work

(See here for all releases)

Sente

Sente provides an easy-to-use abstraction over WebSockets and AJAX to help write realtime web apps with Clj and Cljs.
Sente v1.21 is now out!

This is a major release with plenty of new features, performance improvements, reliability improvements, and a number of bug fixes. Big thanks to all contributors and testers! As usual please see the release notes for details. Some highlights include:

• Support for binary serialization, and a new high-speed MessagePack implementation (benchmarks)
• Support for binary compression, and a new gzip implementation
• A new lightweight timer implementation based on work from http-kit
• Decreased dependency size
• Pluggable un+structured logging via Trove

Tempel

Tempel is a new high-level data security framework for Clojure
After an extended release candidate period, Tempel v1 is finally out!

Tempel provides high-level crypto utils to help protect user data. It offers a coherent and opinionated API focused on helping with the toughest parts of actually using encryption in practice:

• Understanding what keys you’ll need (algorithms, parameters, etc.).
• Understanding how the various algorithms/schemes fit together (when and how to use hybrid schemes, etc.).
• Maintaining best-practices over time (e.g. auto migrating from compromised algorithms, auto incrementing work factors, etc.).
• Key management (key rotation, password resets, admin backups, etc.).

It includes extensive beginner-oriented documentation, docstrings, and error messages.

I’m proud of how Tempel came out, and my hope is that it might be a practical and approachable tool that goes beyond the usual “here are all these complicated low-level crypto utils, good luck!”.

There’s a 36 min demo video (36m) that showcases some if the main functionality.

Carmine

Carmine is a mature, idiomatic Redis for Clojure

Carmine v3.5.0 is out now, the first major release in >1 year.

This release includes:

• Structured logging support via Trove
• Support for the latest Redis commands
• Truss contextual exceptions
• Many other small improvements

It also includes the first publicly released (though experimental and undocumented!) next-gen Carmine v4 core. This is basically a complete rewrite of Carmine, using the latest Redis protocol - and incorporating tons of performance and flexibility improvements. This has been a very large and ongoing job, and there’s still plenty of work to do. But I now have the new core happily running in a couple production environments, so there’s definite forward progress.

BTW for folks that might not have been following- Redis itself has had a lot of really cool developments recently. The new dev team seems to be doing a great job and has been very productive re: new features and performance improvements. Salvatore (the original Redis author) is also actively involved again, and introduced a very useful new vector set type that’s a great fit for similarity searching against vectors produced by LLMs, etc.

Talk: Effective Open Source Maintenance Maintenance

So I’ve been actively doing Clojure open source now for almost 14 years (cue clichés about time flying). I’ve made some observations in that time that I think might be useful, so I recorded a talk on the subject.

The focus is on better understanding some of the emotional dynamics of doing (esp. prolonged) open source work. The talk’s directed at OSS users and includes actionable tips on how users can help reduce creator burnout in some small/simple ways.

Other stuff

Lots of other small stuff, including minor releases for Trove (modern structured logging facade for Clj/s), and http-kit (lightweight HTTP server+client).

And of course the usual support on GitHub and Slack, etc. 👍

Upcoming work

• Want to focus on ensuring that all pre-existing work is in good shape as the year comes to a close. This’ll include updating libraries to sync dependencies, reviewing outstanding issues, updating docs and examples, etc.

• Have some efficiency improvements planned for Nippy based on similar optimizations I made while implementing Sente’s new MessagePack implementation. Likewise, want to consider adding cross-platform support to Nippy for efficient binary Clj<->Cljs serialization. That’d be something for 2026, though I may start sketching out a prototype soon.

• First steps toward a big cleanup of Encore to make it smaller and/or more modular. This’ll be the first step toward trying to improve Babashka support across more of my libs (esp. Telemere).
