Dear #databs, #rstats, and #pydata: Jon and I aren't saying you should submit a hilarious #TidyTuesday dataset for @hadley.nz to analyze, but we're not NOT saying that 😌 Time is ticking
I haven't pushed this update to CRAN yet, but tidytuesdayR curation officially works in positron on dev now, and I accepted a python submission last week, so EVERYONE can participate in this effort to mess with @hadleywickham

I'm excited to inform you:
@hadley.nz to join the #DSLab Feb 17, live-coding a #TidyTuesday analysis. Snoop the tools he uses & ask Qs in the chat! 👀

I regret to inform you:
I've challenged him to only speak in Gen-Z slang for the entire Lab & he's accepted 🙊 pos.it/dslab ⬅️👏🏻

Loving all the #TidyTuesday shares this week!! Just sad that all my corporate finance and corporate accounting classes didn't prepare me to easily understand the data 🤣

Made a quick video showing:
- what the git integration in #Positron looks like
- what running a Shiny app locally in Positron looks like
- how easy it is to push an update to a live Shiny app hosted on Posit Connect Cloud (I'm just using the free version here!) #rstats #databs

ADMIN DAY! Tabs = closed, software = updated, emails = being done, compliance training = barf!

A day with no meetings is like the only way this happens. TAKE AN ADMIN DAY! Next, editing / publishing DS Hangout & DS Lab videos 🎥📹📽️

Love that all my "video" emoji options are old tech ❤️

If you stay to the end of this episode with the amazing @emilyriederer.bsky.social, you'll get to hear something really cooooool!

Also, listen for this lesson: watch people code whenever you can ❤️

Thanks for letting me get back in teacher mode as I live-coded my way through the DS Lab today 🥰 It was sooo much fun & I just hope y'all had fun, too, & learned loads about both {ellmer} and {mall}! I freaking love this unscripted time to paircode with virtual #databs buds each week pos.it/dslab

Chaos code the random fun idea.

We can get so caught up in reproducibility that we forget some code is art. Don't let anyone trick you into believing that your creations aren't worth anything unless they're productionizable. There's still joy in creating with abandon, in fever-dream-coding #databs

I'll be sharing R code and @theotheredgar.bsky.social will be sharing Python code, so come get a glimpse of both! (Finally found Edgar on bluesky 😂)
Tuesday (tomorrow) Jan 27th @ 12 PM ET, Edgar Ruiz will join us on the Data Science Lab where we will live code our way through a tour of the {mall} R package (which means we'll touch on {ellmer} too!). Register at pos.it/dslab

Come see how {mall} works & hang out w/ pals!

I'm getting a 3D printer 🏗️ Got any resources & advice? Except for which one to get because that bell has been rung 😂

In another life, I was a CAD drafter (site plans, redlines, assessment floor plans) - are those (rusty) skills gonna come in handy with 3D printing? Any #databs 3D printing folks? 🤔

It is such a human thing to ask, "is it just me?" 🤔 You're an n=1 experiment. You can wonder all day long if what you're experiencing is normal, average, expected (some of those things aren't helpful, but you get the idea), but the way to really find out is to talk to people. Even when it's scary ❤️

I don't miss childhood, mine was garbage, I just miss the ability to plug into a pixelated video game or book or craft project for 12 hours and not feeling the passage of time 😫

This is the stuff I wish I hope to see more of. In a sea of similar posts about #vibecoding, it's refreshing to read @sara-altman.bsky.social & @simonpcouch.com digging into the whethers /whys of AI's utility in data analysis. We need lighthouses in this #AI storm 🌊 #databs

#ADHData POV: I've worked too many hours already this week, but feel convinced I've done almost nothing 🙏🏻 Love this for me!

Writing down what I've done helps, but that becomes impossible while living in reaction mode. Every slack DM includes a bevy of new tasks to drop the ball on. #databs

#databs nerds, gimme all your thoughts on why using the 10yr/2yr treasury spread inversion as a leading (as opposed to lagging, not "leading" as in "best") indicator of an impending recession is good/bad/unhelpful/fraught 🤔 📉

Just curious, hoping to chat with fellow nerds & learn

This is in 12 minutes!! Come see how to structure your R projects so that Future You doesn't hate Past You 😂
#rstats #databs

Also, be nice to me, my eye is all messed up and I can't see well today 🙈 See you there!!
Join me, @libbyheeren.bsky.social, and @ivelasq3.bsky.social for @posit.co's Data Science Lab @ 12PM ET TODAY!
I'll be walking through how I use the R package structure to work more efficiently and the tools I use to do it!

DID YOU MISS the very first #DataScienceLab when @isabelizimm.bsky.social and @davisvaughan.bsky.social joined us to talk about some of our favorite #Positron settings? Some folks had asked so I wanted to share!

It's up on YouTube here: youtu.be/QIYyeuZ_ISY

My #AdminDayWednesday got overtaken by shenanigans, so I'm carving out THIRTY MINUTES of today to close all my open tabs. And you know what that means! IT'S TIME TO PLAY, HOW MANY TABS DOES LIBBY HAVE OPEN?!

The answer is 89 browser tabs 🙈

Only 4 of them are Jira 😚 proud of me

I'm off homebrew completely. I don't know why, but it just created a layer between me & my installations that made everything harder. Maybe it's because I don't know what the heck I'm doing half the time, but I can't be the only one. Python installs are now uv, everything else is direct 😅 #databs

TOMORROW! (Tuesday)
@andrew.heiss.phd is gonna be on the DS Lab showing us how he makes his life easier: #Positron extensions he loves, OS tools he uses, and #duckdb + Connections pane 👀

Bonus, we'll def share the "moving the activity bar" thing live, too 👏🏻
