I freaking love voice messages. If you're my friend and you're not a voice message person, I'm so sorry about all the friend podcasts I regularly send you 😂 When they get particularly long and rambly, I just end them with, "like and subscribe!" to cut the awkward tension of realizing I'm 5 mins in 😎

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 🤣

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

Emily is the GOAT!!
The thing I admire about @emilyriederer.bsky.social is that she takes tacit knowledge about so many aspects of data science, statistics, and data engineering and makes it explicit.
Really great podcast with her on the test set!

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 ❤️

#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

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
