I've written what monoblok does several times over in Go and Python over the years, probably badly. It would have been nice to clean up my @nats_io firehose subjects with a few rules.

[monoblok @monoblok_]

monoblok accepts publishes from existing NATS clients and exposes useful subjects, saving you from having to write and deploy the same cleanup/republish services.

[Alex Reid @AlexJReid]

I've been messing around building a matching engine in C that attempts to distill the essence sensibly. It's a learning repo, not a thing to use.

[Alex Reid @AlexJReid]

I've long been interested in the LMAX architecture. It still receives a lot of attention due to this Fowler article back from 2011: https://t.co/B2JHlFqnTu

[Alex Reid @AlexJReid]

Just because it worked once in an environment with a specific set of constraints does not make it a general purpose silver bullet Just embrace the Good Ideas. But what are the good ideas? This requires a bit of thought.

[Alex Reid @AlexJReid]

As well as @nats_io clients, browsers can now connect to @monoblok_ via built in HTTP gateway. See it in action on https://t.co/gUcLFfrbKw

[Alex Reid @AlexJReid]

monoblok adds support for @nats_io durable consumers. Preview functionality in monoblok v0.3.5. https://t.co/tBOyNL20jy

[monoblok @monoblok_]

monoblok can now consume (and catch up) from @nats_io JetStream streams. It observes a virtual clock so stream date is used. May add event time from JSON payload and/or application header. Hooks in to existing export machinery so replay emissions can be optionally exported back.

[Alex Reid @AlexJReid]

Code is data/data is code. S-expressions put some people off, so monoblok patchbays can now be written in sugar-coated YAML.

[monoblok @monoblok_]

You can now write your patchbay configurations in YAML

[Alex Reid @AlexJReid]

If you happen to fall into the vast intersection of people who have an ESP32-C6 board lying around and want it to publish sensor readings to NATS...

[monoblok @monoblok_]

tinyblok can now be flashed from Chrome https://t.co/SLxxLThvTk

In setup mode just join the TINYBLOK wifi network. A captive page pops up, allowing you to select your wi-fi network and target NATS environment.

[Alex Reid @AlexJReid]

tinyblok can now drive a little OLED! Crucial feature

[monoblok @monoblok_]

I found a less Soviet era display!

[Alex Reid @AlexJReid]

@thanconnolly @monoblok_ @nats_io Codex may well have done it. 😄 https://t.co/dqqbvgb36J

[monoblok @monoblok_]

Writing a monoblok patchbay by hand is already simple.
Describing it to an LLM is faster: give it the shape you want your data in and get back a setup (with test publisher) that publishes clean/actionable values to your @nats_io cluster.

[Alex Reid @AlexJReid]

Love this so much and I totally believe there was a team and PM and roadmap

[Paul Bohm @paulbohm]

If your startup does not have a UUID microservice you’re ngmi

[monoblok @monoblok_]

The same telemetry cleanup code gets rewritten in every subscriber.

monoblok moves it into the broker with a simple DSL
raw → round → squelch → clean

[Alex Reid @AlexJReid]

Tinyblok on ESP32 dev board can now respond to @nats_io req/reply. Useful for pings, queries and hardware actuation. Also great for querying device fleets: if n boards all subscribe to the same subject, the request is a broadcast and n boards (should) reply.

[Alex Reid @AlexJReid]

https://t.co/cIIXv0WB5v now uses nats.zig instead of nats.c - also zig 0.0.16.

Quite a journey; addresses a gap nats.zig has on Windows.

[monoblok @monoblok_]

monoblok is a tiny pubsub broker with a conditioning streaming DSL. it cleans and shapes local streams and then exports the results directly to a NATS cluster, or through a NATS leaf. Conditioning at the edge, analysis in the cloud. https://t.co/sQv2WThQnO

[Alex Reid @AlexJReid]

@HardlyLoose VW had Formule-E in the 80s (or it could mean eject or evade-the-law)

[Alex Reid @AlexJReid]

Great to see; monoblok does something similar but expresses it in a DSL rather than via headers. I can see merit in each; either way, very cool.

[Synadia @synadia]

@nats_io @every Subject sampling = server-side downsampling.

Sensor pushing data every second? Schedule a snapshot of the *latest* value every 5 minutes and source it into another stream.

Less data on the wire to your cloud, no client-side aggregation logic.
