I enjoy using it and playing with it, but so many use cases can be addressed with something simpler - either just Docker / Swarm / AWS ECS etc. alternatives or just going for VMs with well defined CI/CD processes that let you tear down the infrastructure and set it up again easily.

What very interests me are the concepts K8s build on that are not usually recognized - to me K8s seems a lot like a JVM, just that it operates on infrastructural (and not runtime) level.

I enjoy experimenting with these concepts when applied back in the runtime world - it is for instance interesting to run 100s of servers with JVM and let them load/execute new dependencies and code at runtime (JVM is very well suited for that).

This is area that is not yet explored and would probably deserve more attention as it allows for distributed rapid computing that is infrastructure/platform independent (the downside is that it requires (just) JVM and the isolation is not perfect).

E.g. If I am net long in my portfolio and I fear some headwinds I can buy a put or two for the peace of mind. Now those puts should be always considered as worthless, and it is just the price to pay for the peace of mind.

Similarly you sell options. Trading options on the other hand is just pure gambling. Even if you get the direction right you likely won't get the timing right (or the volatility).

I guess now the question is if Nubank could/will also promote Clojure and to what extent (or if they will support Cognitect enough to do that). I would wonder if they went through that thought process and what RoIs for that are from their perspective.

It might even take much lesser investment than equivalent of $1bil from 90s... The Java/JVM market is huge so it might need just a little nudge :)

Within the JVM ecosystems it seems that basically Kotlin (as nice as it is) has been stealing some market share that might have belonged to Clojure. And all that just by selling some cheap cut syntax sugar on the corner.

There definitely is a huge desire within Java/JVM community to innovate and if approached correctly Clojure could actually shine - there are just few misconceptions and fears that could be put to sleep by some smart marketing strategy. Nubank is great first step in that direction, because it gives an example of a mature large yet innovative company relying on Clojure in production.

Yes, I would still be careful with passwords in the public beta.

It goes via SSL and you get a unique UUID URL so all-in-all it is kinda secured (plus time-to-live of the instance is only 3 hours which limits any time to hack it) but still this is not 100% secure and I would not recommend it for any kind of production use (including any use of passwords you dont want exposed).

The free instances are not (yet) password protected (other then the UUID) - this on the other hand is useful if you want to share the envrionment with somebody, just send them the link... This is just a beginning of the public hosting so I will need to think through further improvements that would go into the hosting, security-wise and other aspects as well.

My main objective at this stage for the free hosted instances was to give people way to play with Titnaoboa or quickly test something, especially if something is not working in their local environment (say dependencies) and they want quickly re-test in vanilla environment.

If you want to add aws secrets or what not I would suggest to just download/install your local version, it is super easy: https://github.com/mikub/titanoboa#installation

Or if you need a public IP to integration just grab the docker instance and spin it in your AWS ECS or something.

It is similar with what I am seeing - i.e. lots of older integration systems are terrible with data simply because they force you to use some way of data modeling (e.g. their OOP data models, WSDLs/XSDs etc.) while the newer ones just rely on json which is good but can lack the (sometimes necessary) complexity. To do some data cleansing on the way then seems like an unachievable task (there is certainly such a thing as overdose on XSLT ;) ).

I also like the approach you took with centralized data dictionary - it certainly is something the industry might need, I would wonder how it impacts change management though (especially in bigger companies).

Wishing you good luck!

I will definitely check out Syncari - just opened the landing page and it looks great!

I just (sequentially) restarted all 4 servers behind my 2 load balancers - seems that by reaching 100 containers in each geography the provisioning threads may have died after many (unsuccessful) retries, so need to restart the thread pools.

That is one more error I need to handle (or increasing my limit in AWS).

I just picked up the more restrictive license at the beginning - being a sole funder and not working on this full time etc. I simply did not want somebody (e.g. a big company with a big team) grabbing my code along the way and running away with it.

Since now Titanoboa got to the shape I envisioned it to be in I am starting to focus more on adoption, so yes I am definitely thinking about switching to less restrictive license since it will probably help.

Also at the beginning I was not aware how badly AGPL is perceived (I always thought if it was good for Mongo it could work for me, but I may have been wrong).

I also am probably not good with names as my other alternative was Megalodon (4 syllables) - I just wanted to have some megafauna name.

Happy to hear what you folks would suggest :)

The no-code is an illusion in the enterprise realm - before you know it, you are waist deep in the custom code.

No-code can really work only for small businesses imo.

I come from enterprise background and that is one of the reasons I built Titanoboa - to make something that makes it easy to rapidly prototype new integrations on the fly.

I summed up some of my thoughts on this topic here: https://www.titanoboa.io/repl.html

The main point I am trying to test with Titanoboa is this however:

State Machines <-> Process Designers is a spectrum and one product could handle the entire spectrum (or part of it).

Titanoboa makes it possible to pre-define workflow steps and make it "no code" while also making complex custom integrations possible from the same environment with the same concepts. Plus also distributed data handling is in the mix.

I guess now the challenge is how to market this versatility or whether it could create more confusion...

Obviously this is for JVM, plus I am not sure how Prefect addresses following two points I mainly focus on:

- make rapid prototyping of new steps possible during runtime, without any need to restart/redeploy

- focus on distributed processing, where in master-less Titanoboa cluster you can have pretty much any number of nodes
