Happy “did my code contemplate the existence of leap days” Day to all who celebrate!

It's easy to learn the basics (loops!) or pkgs in a new language, but it's harder to rediscover the "didn't know I needed it, don't know to call it, can't live w/out it" utility fxs

That's the topic of my next Rgonomics post for users

Topics include:

⏰Unpainful datetime wrangling (ala lubridate)
✏️Elegant string interpolation with f strings (ala glue)
🔁Concise iteration with list comprehensions (ala purrr)
🪄Mock data creation (ala seq, rep, data.frame, etc.)
💾Saving objects with pickle (ala rds)

It's an odd post in a way since, like tools on a workbench, it's just "here's some stuff you might need sometime so it's nice if you have it there when you want it"

Appreciate any meta-takes on the style / structure / content / etc.

@ijlyttle That's really interesting! I can't say I've encoutered a need/use case that has sent me down that specific rabbit hole yet, but that's a fascinating example of the kind of things we take for granted. It's also interesting to think how the with keyword is vaguely aimed in the same direction yet feels so underpowered relatively

Will let you know if I have to dig there and would love to learn what else you find!

Continuing my look at pkgs for converts, this post explores polars ergonomics beyond the basics -- column selectors, window functions, nested data, etc

It's impossible to overstate @xieyihui's impact

R Markdown taught paved the way for best-in-class literate computation, became a core tool of open science, enabled some professors to share resources as free websites, inspired other professors to become textbook authors,

helped create the strong blogging community, made learning new packages even easier and more accessible with generation of pkgdown websites,

saved us countless hours and errors copy-pasting code outputs into decks and docs, saved as plaintext and version controlled cleanly like Jupyter Notebooks never would, gave even the most passionate pythonistas something to covet from the world,

But the thing is that's not all. Beyond the flashy projects, @xieyihui was still boots-on-the-ground, answering out countless StackOverflow questions, writing books to guide the way, graciously welcoming first time contributors to his projects --

all while emanating a kindness rare in open source "royalty" or, frankly, our world today

For what @xieyihui developed, we are all in his debt, but for what and how he created more broadly, we should be thrilled to support his next venture!

It's a once in a lifetime opportunity to help support whatever he will unleash next

New Year, New Site -- after many hacks to preserve all my post / talk / RSS links, I'm finally ending 2023 by switching my blog down to Quarto!

Didn't write much in 2023, but I'm hoping Quarto's nice, lightweight framework will lead to a productive 2024

Not sure where I'm going to take this but one final mini-project in 2023 is a small Node.js CLI app that enables cross-posting either single-posts or threads of any size to both Mastodon and Bluesky. I used it to post this thread (which I've deliberately made a thread to ensure it works, though some folks likely saw garbage ipsum latin test posts over the past cpl hours). It should do a decent job splitting at words, but I may add more intelligence to the splitting.

For now, you need to use app

@hrbrmstr This sounds amazing! Is the repo private perhaps? I get 404

Any -ers have learning python in their 2024 resolutions?

Learning a new language, it's hard to abandon the workflow you know and love. In my last post of 2023, I recommend some of the latest python pkgs/versions with similar ergonomics

Have any Quarto users built custom listings they are proud of? I'm trying to mimic some of the Hugo Academic / Wowchemy listing features I miss and would love to crowdsource some examples

Causal inference in industry should be advantaged by greater data & context on past obsv data, but this advantage can only happen with proactive data, metadata, and knowledge mgmt

In this post, I look at the needed assumption of common causal techniques and work backwards into the implications for information management strategy
