Veerle Eeftink - van Leemput

Can you see the LMS/website behind me? 👀

It’s @athlyticz.bsky.social and I’m excited to share that I’ll be joining the leadership team! Exciting times 🤩.

My role will be to help streamline ops, bring in more awesome instructors (lmk if you are one 😎), and help the platform scale!

I was never on Twitter either, maybe that’s why?

Been a bit quiet here 🫢

Yes, part of the reason is that I still am on maternity leave (or parental leave, whatever you call it, my baby is 9.5 months old). So different priorities.

But another reason is that I don’t like the short form format. I always have too much to tell 😂😅. Am I the only one?

Shiny - Build Your First LLM App with Shiny for Python or R Shiny is a package that makes it easy to create interactive web apps using R and Python.

💡 What happens when you take everything you've learned about LLMs… and turn it into an app people can actually use?

In Part 3 of The Shiny Side of LLMs, we build DeckCheck — a Shiny app (#RStats & #Python) that acts like your Presentation Rehearsal Buddy.

In Part 2, “Talking to LLMs: From Prompt to Response”, we get hands-on with LLM-powered apps. This guide is for #Python & #RStats users who want to go beyond the basics.

Part 1: "What LLMs Actually Do (and What They Don't)" breaks down complex concepts like transformers, hallucinations, and RAG in simple terms.

Shiny Source Code Explained: Secrets of Observers - Hypebright Shiny observers, like the observe() function, play a crucial role in Shiny's reactive programming paradigm. How do they work? Find out here!

New edition of "Shiny Source Code Explained" 😎✨

This time all about #rshiny observers and their little secrets!

For me, yes, same preferences really!

* keep language simple and avoid too technical terms, especially for beginners
* analogies to help learners who like to visualize things in their minds (that’s me 🤓)
* I like workshops to be max 3-4 hours with a 15 min break after a max of 90 minutes

Some of things I like to integrate:
* plenty of time for questions
* keep code short and to the point, serving a full blown pretty Shiny app at the start will only be distraction for the problem at hand
* make examples fun and suitable for the audience
* hands-on and make it interactive

Great to hear! 😀

Unfortunately my experiences with reticulate were always mediocre at best. Too much hassle, especially when it comes to the environment and using it together with renv. So I totally get you. Maybe with the new uv integration it will be better though, have to put that to a test!

If you have specific branding you can use brand.yml in combination with bslib - makes it easy to get the logo, colors, typography and that kind of stuff right!

Nice! Didn’t know something like that would be possible with vim (but tbh vim terrifies me so how would I know 😂)

For RStudio, Positron and VSCode 😎

Yeeeey Libby on YouTube 🥰 and with a great initiative for the Python community!

I like blog posts with a good title 🦥- especially if they are about R and you can learn something new!

Yay! Thanks for sharing and I’m happy to hear it’s easy to read- that was exactly the goal! 😀

Great start of the week! 🤗

If you want to share your #rstats #rshiny mobile experience, you can reach out to Julian here: www.linkedin.com/posts/julian...

And I would also love to hear about your mobile adventures, so keep me in the loop! 👀

Those problems can be: typos, bad formatting, or forgotten browser() and print() statements. There's a variety of hooks available! See more here: lorenzwalthert.github.io/precommit/

In today's spotlight: precommit 🪝

A pre-commit hook is like a checkpoint. If the hook finds a problem, it stops the commit and tells you what to fix.

In #rstats, you can add pre-commit hooks with precommit 📦. Built on the pre-commit framework it provides useful hooks specifically for R.

Thank you! 🤗

Thanks!
