Continued thread
As much as I love plain text accounting, there are subtle things about it that make me want to write a program. That's a lot of how I do my book keeping for my publishing company and apparently how I'm handling Partner's babysitting.
The only difference is that this uses Deno instead of Node and I'm trying out hledger verses beancount. Mostly because I wanted to try out puffin which I don't exactly like. But, hledger is more popular than beancount so I might as well let them war in my head for a while before I decide on one or the other.

Looking for CMS advice
Hey Web devs!
Do you have any suggestions, tips, opinions, dos, don’ts about headless CMSes?
I have a growing list of small/mid non-profits and collectives asking for my help to (re)make their website. I totally want to help, but I don’t have much time, especially considering that they generally have little or no funding—I would most definitely point them to @VillageOneCoop, otherwise.
Therefore, I want a super simple and replicable solution where I can copy-paste most of the code, while providing them with a stable, fast, and modern solution. I had a look at the Headless CMS section in the Jamstack website, but I need opinions from people who actually used some of that software already.
Needs
- I want to code and configure everything using @eleventy
- Admin interface (#WebApp) for the client to add pages and write posts
- Static website in the front-end
- Simple and reliable CI/CD
- No/minimal maintenance after the first setup
- Self-hostable (I was taking this for granted so much that I forgot to write it)
- If it requires forge integration, it should support #ForgeJo
- #OpenSource
Nice to have
- Possibly using #Deno, not #NodeJS
- Allowing the client to customize a bit their website through the admin interface, with a GUI
- CMS app packaged on @yunohost
- No CMS vendor lock-in
- I’d love to write as little JavaScript as possible
- #FreeSoftware
Absolutely not
- Front-end #JavaScript frameworks
Please, boost this and ask around! Links to videos, tutorials, and resources are welcome.
People whose perspective I would really value: @zachleat @harryfk @deno_land @jaredwhite @vanillaweb @stefan @mxbck @WeirdWriter @deadsuperhero (Sorry if I am spamming you!)

#Pipelight typescript issue fixed.
It was a nasty bug that slide in with #deno 2.2.
Fixed by replacing external #UUID library with bultins uuid library.

Want your own custom AI thats trained on confidential material?
Here's how you can build a custom RAG AI agent
Deno BlogBuild a custom RAG AI agent in TypeScript and JupyterAI and LLMs are certainly useful assistive tools. But what if we need to train LLMs on confidential documents and materials? Here's how you can build your own custom RAG AI agent.
Is the world in need of a federated Craigslist/Kleinanzeigen platform? I am currently thinking about a project to dig into #fediverse development and learning #golang or stay with #deno and using #fedify.
EDIT: There is already something like that on the fediverse! It's called Flohmarkt. Thanks for the comments mentioning that!

Big shoutout to Node.js for adding TypeScript 
But how is it different than Deno's "first class" TypeScript support?
Here's an overview of what you can (and can't) do with TypeScript in Node and Deno.
