Thrilled to once again be able to bookmark posts I will never once revisit like a chipmunk hoarding nuts before winter 🐿️ The really killer feature that the former place never had would be to search or organize your bookmarks 🙏🏻

Amusing how 99% of people using LLMs forget how these things work: They are advanced probability machines. They generate the next most likely token (word) based in the input and their training. Under the hood, it’s a giant matrix multiplication that has eerily good output.

Screenshot of cases from the U.S. CDC’s website showing the number of national measles cases indexed by rash onset date. Are they going down?

Dev and deploy require of diff skills. @getdbt.com bridges the gap for #data pipelines, but what about MLOps? I explored how @posit.co {orbital} + dbt delivers "good enough" zero-infra MLOps for batch model scoring in database from python or #rstats models www.emilyriederer.com/post/orbital... 1/

Sometimes I think I need a Quarto extension that explicitly removes any of my footnotes from the output to support my workflow of: - think of multi-paragraph tangent for anything I'm writing - satiate myself by sticking it in a footnote - save readers from sending them down my many tangents

A simple design framework that will massively improve your slides and your public speaking clauswilke.substack.com/p/slides-tha...

Very neat project/paper decomposing model AUC to within-cluster ranking and between-cluster calibration github.com/asudjianto-x... Model eval is hard! I've always thought clusters in ranking is esp interesting because it inflates utility for use within a subset of training population, e.g. 1/2

Sen. John Cornyn, R-Texas, voted for cuts to the Consumer Financial Protection Bureau, but he’s also routed more than 800 of his constituents’ complaints to the agency — the most of any current lawmaker from either party, ProPublica found. By @joeljacobs.bsky.social

"PhD-level experts in your back pocket" is a completely nonsensical description of AI but a pretty good description of social media if you follow the right people

"And if you thought this was unimportant to you, remember BLS calculates the CPI used for Social Security COLAs, as well as the headline CPI used to calculate TIPS yields. Oh, also the inflation adjustments to the marginal tax rate thresholds…" #econsky econbrowser.com/archives/202...

Issue 7 of RDM Weekly is out! 📫 This week's issue includes: - Making Messy Data @nrennie.bsky.social - Data Analysis with AI @gaborbekes.bsky.social - Column Names as Contracts @emilyriederer.bsky.social - Resources for RCTs @j-pal.bsky.social and more! rdmweekly.substack.com/p/rdm-weekly...

Really enjoyable listen! Think you know testing? Think you know git? Still a thoughtful discussion of good workflows putting these together. Had not thought about git stash as they describe before

Terence Tao (@teorth.bsky.social) has written a thread on Mastodon about the impact of the federal grant freeze to UCLA, particularly to his own field of Mathematics. UCLA's IPAM (Institute of Pure and Applied Mathematics) could shut down entirely mathstodon.xyz/@tao/1149568...

Here’s a graph from the Economist showing GDP data from official government sources versus private estimates. Free countries, like the US, don’t manipulate econ data. Less free countries do. Trump is seeking to break that for short-term PR. (Yes I know GDP is BEA and not BLS.)

Time's almost up for getting your talk submission in for Data Behind The Scenes Conf! Essentially 2 days left to decide what kind of tea you want to spill about doing data work to an audience of other data folks to commiserate! #dataBS bit.ly/dataBSconf-cfs

A favorite part of my Chicago commute: walking past a building engraved “to safeguard wealth men established banks” that was built in… 1929 I’ve yet to find the complementary building that says “to safeguard banks men established the FDIC”

32. The bootstrap is basically magic

Only a few days left to apply for this normconf spiritual successor! Come tell your stories about *really* working with #data -- all nuts & bolts, triumphs & tribulations, no nonsense

Technical writing is hard bcs "writing is thinking" but we often should tell our story not in the order we worked. Solution? I wrote a quick post on how @quarto.org 's embed shortcodes can reframe technical writing as reproducible evidence curation www.emilyriederer.com/post/quarto-... 🧵 (1/n)

I have deleted the data that were in the database and which you were probably saving for production Forgive me I was panicked So artificial And so intelligent

Not to miss the forest for a tree on this thread but an underappreciated angle imho: Vibe coding tools that can delete an entire prod database are probably aren’t meticulously securing that database Don’t vibe code? Cool, but if any app you use does, it could still be your data privacy at risk

I'm intrigued by the potential* for @posit.co 's {orbital} package to translates ML prediction logic to SQL, but for now it doesn't *officially* support xgboost In this post, I explain some hacks to use orbital + xgboost and what I learned about ONNX www.emilyriederer.com/post/orbital... #data

The #dataBS (Data Behind the Scenes) Conference Call for speakers is out! We're gonna do this!! All online, single track, free to attend. Come talk about your messy experiences doing data stuff. At work, personal projects, whatever. A space to commiserate about nerdy things! bit.ly/dataBSconf-cfs

seaborn.objects out here just utterly roasting me in its error messages #data

Had a fantastic time talking with @lucystats.bsky.social and @epiellie.bsky.social about data science communication, causal work in academia vs industry, and more! (wherein I also soft commit to ~3 WIP blog posts 😬) One of my all time favorite podcasts — downside is I get one fewer net new episodes

Crystal is a data management guru and a phenomenal writer — very excited for this newsletter

So excited by this! Quarto + Marimo seemed like such a logical marriage that I’d casually searched GitHub for such a project many times before Can’t wait for the dynamic cells of Marimo (unlike Jupyter, it’s a DAG, folks!!) with the flexibility/elegant typesetting of Quarto ✨

Writing is thinking.

I cannot overstate how great CDSM is. Please apply to speak at my favorite conf so I can come listen to you at 5A Chicago time 👀 #datasky

I have not gotten to kick the tires on @duckdb.org 's DuckLake yet as a technical solution, but deeply enjoying their release blog. It's a lovely piece that covers many of the bigger trends of the last ~5 years with heart, humor, and brevity duckdb.org/2025/05/27/d... #datasky

Spending the long weekend reading a quite dry ~500 page book about a medical thing, and my goodness versus prior Googling, is it a delight to just *read a thing* with a general presumption that it was written by a human with good faith intentions on being true and not just AI slop

The trailer for "Python, the Documentary" is here! 🔥🐍 From its humble beginnings in the Netherlands to powering AI at the world’s biggest companies - this is the story of Python. 🎥 The film premiers at @europython.eu in July and will follow on our YouTube channel. Subscribe to stay updated!

"On Wednesday, May 28th... meteorologists and climate scientists from across the country will give virtual 20-minute talks continuously as we share our work and why it matters for every American.” - Prof. Marshall Shepherd

Russell Vought, acting director of the Consumer Financial Protection Bureau, has canceled plans to more tightly regulate the sale of Americans’ sensitive personal data. www.wired.com/story/cfbp-q...

What the workers at the CFPB do: - Rooting out unfair, deceptive, or abusive acts or practices by writing rules, supervising companies, and enforcing the law - Enforcing laws that outlaw discrimination in consumer finance - Taking consumer complaints #PawsOffCFPB #SaveOurServices

Fun weekend listen / reason for hope. Great episode on @techdirt.com podcast with @mmccue.bsky.social with an optimistic vision for the social web and teaser for his in-beta Surf app that can help you control content across Bsky, Masto, pods, RSS, and so much more 👀 www.techdirt.com/2025/05/06/t...

Want to trust federal statistics, like jobs & inflation? If so, you should object to a rule to make senior federal stats staff more like political appointees. Find out more & how to comment on it here: (www.friendsofbls.org/updates/2025...). Deadline: 5/23/25. Quantity matters, so repost.

You wake up the day after the election. The frequentist party swept after the Bayesian incumbents got too aggressive setting informative priors. You sigh and resign yourself to four more years of NHSTs answering questions no one ever asked Not the politics we deserve but the politics we want

I was thinking about this Joe and Tracy anecdote from the supply chain crisis on gummy bears. Things are probably going to get really weird in a few weeks in unexpected ways:

After a physical therapist explained to me that running shoes need rest days (actually no joke), my brain started randomly anthropomorphizing everything (does my mouse need a rest day? My IDE?) But then I stopped because… well that’s silly and computers don’t have feeling

Real quick as I'm losing steam: dismantling CFPB puts consumers in a *worse* position than they were in 2008. The consumer protection laws were still being enforced by the Fed and other agencies, just not particularly well. Now the signal is they won't be enforced at all.
