Happy 2026! 🎆 My resolution: put @dslc.io on a sustainable footing. I’m soft-launching our Patreon to cover costs (Zoom, hosting, etc). If you love #TidyTuesday, our Slack help, or our book clubs, you can be an early supporter before the official launch Monday! patreon.com/DSLC #RStats #DataBS

@libbyheeren.bsky.social is always telling us to work out loud so I'm going to spin up a thread about the soccer analysis work I've been poking around at. I'm a big supporter of the USL Super League / Gainbridge Super League and have been messing around with modeling playoff probabilities.

I calculated a soccer-specific chess rating for 4,400 online games between ~100 players' accounts Top 10: 1. Marten de Roon 2. Yussuf Poulsen 3. Antonee Robinson 4. Stefan de Vrij 5. Borna Sosa 6. Christian Pulisic 7. Michael Olise 8. Kevin Prince Boateng 9. N'Golo Kante 10. Josip Stanisic

if tumblr dies I need this video to make it's seasonal rotation here instead just in case, Happy holidays 🎄

I just need 1 more dataset for #TidyTuesday 2025! Thank you so much to those of you who have submitted datasets! The submissions have allowed me to make progress on a long-planned huge maintainability and usability improvement for TT, coming in 2026!

I wanted dinner recommendations so I scraped 13,000+ London restaurants and accidentally discovered Google Maps is running a shadow economy. Anyway here's a dashboard and a political economy thesis: open.substack.com/pub/laurenle...

anyone else panicking over xgboost releasing a cran update last week that broke their legacy saved models? just lost like eight hours of my life strugglebussing a fix, it was awful, the code I used to fix it was awful, and i hate everything. might write about it later as therapy/closure #rstats

Data science folks: Can you recommend any textbooks/classes/resources that you really enjoyed, or that you felt made a particular difference in upscaling your skills? Asking for a friend who has some use-it-or-lose-it professional-development funds to spend before the end of the year.

Randomly decided that it's time for Tantastic Food Takes - here's a thread of the top things I ate in London on my recent trip (featuring Donia, Gymkhana, Dishoom, Quality Chop House, Regency Cafe, and Singburi)

-- WEEK 13 #NFL 🏈 Playoff Leverage -- Here you can see 1.) how the playoff probability of each team changes depending on whether they win or lose the next game, and 2.) the combined playoff leverage of the teams involved in each game, sorted by kickoff time.

including a few days of travel recovery time into PTO planning is superb stuff - slept for 12+ hours when I got home from London and now casually unpacking and doing laundry and getting ready for the week is 10/10. alas, if only liverpool were not shit right now that would be excellent

I'm honoured and delighted to be delivering the keynote for Japan.R 2025 in Tokyo on Dec 6. New ideas on creativity and community in open source software. Live demonstrations of ggbot2, OpenTelemetry and mirai (Posit ecosystem-wide initiatives). #Rstats #Tidyverse japanr.connpass.com/event/374714/

Good morning, it is 9am here in London. I am confident that the woman who wrote fifty shades of grey was inspired by the London skyline. However, I am happily on my way to pickup volleyball by tube so I have zero complaints.

testthat 3.3.0 out now! This is a massive release with tons of improvements including better failure messages, new expectations, improved snapshotting, new vignettes, and much much more: tidyverse.org/blog/2025/11... Post includes some thoughts on developing an #rstats package with Claude Code.

Landed in London for hudl/statsbomb conf, looking forward to hanging with the soccer gang tomorrow!

Post is up! #rstats rfortherestofus.com/2025/11/quar...

Here's a thread of some scattered thoughts about Jordan Spence, first star of last night's Ottawa win over Utah. He is a very good and very unusual player, which is to say: my favourite kind of player.

pre-writing a devastating obituary for your enemy is god-tier hating of a kind you don’t often see anymore. renaissance haterism. beautiful stuff.

We have a loaded lineup this year that includes @lvanden.bsky.social, @jperline.bsky.social, Gerard Cuenca (UEFA), Peter Tea (Sportlogiq), Dee Kundra (Bayern), Martha Reyna (Statsbomb), and many more! isac.baquora.app/conference/s...

Incredibly excited to be hosting @sethpartnow.bsky.social , Katie Krall, and Josh Orenstein this Thursday (11/6) for a panel on how technology and data are changing the essence of sports at the 3rd edition of the ITAM Sports Analytics Conference ⚾️🏀🧑🏼‍💻 Registration is still open: luma.com/junz793a

Wrote up a little intervention post/explanation for my class about why using LLMs for trying to learn programming (as first time learners!) is bad and detrimental datavizf25.classes.andrewheiss.com/news/2025-11...

time for a world series walkoff hbp

And we have now progressed from data analysis to policy recommendations. I told her that we'd calculate the cash value of her candy haul, that I'd ask her to raid her piggy bank and donate 1/3 the candy cash value to a local food bank, and that I'd add on a 5X match.

pumpkin carving 2025.02: big ducky energy 😎

Prepping for a pumpkin carving party later tonight 😎🐥

Strong rec for data people: if you use a library often, go to its GitHub issues, and find something, anything, to fix and submit a PR - nothing teaches you the internals better than doing development - you get software development reps and real code review experience - giving back is good.

When a chatbot gets something wrong, it’s not because it made an error. It’s because on that roll of the dice, it happened to string together a group of words that, when read by a human, represents something false. But it was working entirely as designed. It was supposed to make a sentence & it did.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

Pumpkin szn! This carving is of my current obsession: playing a lot of rec volleyball 🏐

in my happy place

jacobtomlinson.dev/posts/2025/t... Highly relatable for anyone that has ever written a line of code used by other people Lovely little post from @jacobtomlinson.dev

The Blue Jays are relentless

I only need *5* more dataset curations (and to review those 5 plus the open PR) to be done curating #TidyTuesday for 2025! I can definitely do at least one myself, so I just need 4 of you to curate a dataset! Check out github.com/rfordatascie... for #RStats instructions.

i'll be going live at 1 PM PT tomorrow on twitch with a chill stream working on the NFL's big data bowl competition! please feel free to drop in and hang out tomorrow afternoon! www.twitch.tv/john_b_edwards

Live now!

🚀 𝐁𝐢𝐠 𝐧𝐞𝐰𝐬 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐟𝐨𝐨𝐭𝐛𝐚𝐥𝐥 𝐚𝐧𝐚𝐥𝐲𝐭𝐢𝐜𝐬 𝐜𝐨𝐦𝐦𝐮𝐧𝐢𝐭𝐲! We are thrilled to announce the release of our 𝐨𝐩𝐞𝐧 𝐝𝐚𝐭𝐚 – the 𝐦𝐨𝐬𝐭 𝐜𝐨𝐧𝐭𝐞𝐱𝐭𝐮𝐚𝐥𝐢𝐳𝐞𝐝 𝐞𝐯𝐞𝐧𝐭 𝐝𝐚𝐭𝐚𝐬𝐞𝐭 𝐢𝐧 𝐟𝐨𝐨𝐭𝐛𝐚𝐥𝐥, covering the 2023/24 𝐁𝐮𝐧𝐝𝐞𝐬𝐥𝐢𝐠𝐚 𝐬𝐞𝐚𝐬𝐨𝐧, including Bayer 04 Leverkusen’s historic invincible campaign.

TOMORROW! Join me on the #DSHangout with @tanho.ca to chat all about... whatever you want! Great topics: R in Production, sports analytics, open source dev work, and pumpkin carving 🎃 ❤️ I plan on asking about my fave: working out loud! You can go to pos.it/dsh to register! #databs #rstats #python

You should read this wonderful little history of the #tidyverse, by @hadley.nz. It reminded me about my early #rstats days as a PhD student (2011 - 2016), where I was constantly trying out the new things Hadley and crew were cooking up. hadley.github.io/25-tidyverse...

Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more: adventofcode.com/2025/about#f... adventofcode.com/2025/about#f...

OK AND, @tanho.ca is gonna be on the Hangout this week, and I'm hoping we get to chat a bit about how streaming or just in general letting people watch you work/fail/struggle/figure stuff out can actually be such a multiplier for your confidence and your productivity and enjoyment!

pair programming is life

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`. It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

I'll be talking at some online events in the next few weeks: this Thurs Oct 23 I'll be on DS Hangout with @libbyheeren.bsky.social, and on Thursday Nov 6 I'll be on the @ropensci.org community call about graceful internet packages! #rstats posit.co/data-science... ropensci.org/commcalls/gr...

6. Everything should be a project or package I'm almost to the point where everything should be a PACKAGE. This has saved me so much time this year. 7. Vignettes, NEWS, Issues Helpful for the developer, user, and managers to follow along. Or even your future self 🤗
