The @tidierjl.bsky.social 2025 Julia Con video is now posted - I did my best to do a 25 min whirlwind summary of all the awesome work folks around the world have helped put together, from dataframe logging, databases and plotting to web scraping and more!

I really enjoyed giving a brief introduction to Julia for statisticians yesterday - thanks to Jake Grainger and Charles Dufour for organising such a great session!

To borrow another example, taken from the `dbreg` README: github.com/grantmcdermo...

Here I am running a fixed-effects regression on 180 million(!) row parquet dataset... and it completes **< 2 seconds**... on my laptop 🤯

This is powered by @duckdb.org under the hood.

Running dbreg::dbreg() on a full year of NYC taxi data... and it takes less than 2 seconds. dbreg( tip_amount ~ fare_amount + passenger_count | month + vendor_name, path = "read_parquet('nyc-taxi/**/*.parquet')", ## path to hive-partitioned dataset vcov = "hc1" ) #> [dbreg] Estimating compression ratio... #> [dbreg] Data has 178,544,324 rows and 24 unique FE groups. #> [dbreg] Using strategy: compress #> [dbreg] Executing compress strategy SQL #> #> Compressed OLS estimation, Dep.

The University of Michigan is now claiming that students have an ‘ethical responsibility’ to use AI.
Questions to ask yourself As GenAl poses to be a revolutionary tool that can change the academic space and beyond, it is important for you to understand why and how you intend to use these new, powerful tools. These are a few questions to consider and note that the answers to these questions will vary for each person. • Is using a GenAl-based tool helping me learn more and think better? • Is using a GenAl-based tool enabling or hindering my mastery of the stated course objectives? • Is the content I generate accurate and verifiable? Is it free of biases that might harm other groups of society? • How will I treat content that might have been generated using a GenAl-based tool? • Is using a GenAl-based tool equitable to my peers in my course? • How can my actions in using a GenAl-based tool lead to the greater good of society? Understand that your usage of GenAl-based tools can give you the means to better not just yourself, but also society as a whole, and there is an ethical responsibility towards doing so.

If you're interested in learning #JuliaLang and are currently an #RStats user (or even if you're not!), then here's a little introduction to getting started! 📊

interesting that microsoft researchers aren’t on this list. seems like somewhere a machine could excel by just making shit up
disabilitystor1.bsky.social Aparna Nair @disabilitystor1.bsky.social · Aug 4
Just a reminder this list is drawn from a piece written by four researchers for MICROSOFT (data scientists, CS people, economists) who have never stepped foot in an archive/never taken an oral history/studied material culture, by their CVs.
Unlike them, I do my research, and don't talk out my ass.

In my address to the JuliaCon community, I shared why it’s such an amazing time to be in healthcare - decades-long problems solved in a short time-frame by modern medicine and the whole gamut of basic to clinical research.

But for this to work, the NIH needs to focus on science, not politics.

As one of the few MDs wearing an n95 in all pt rooms, I gotta say, not getting sick all of intern year was incredible.

I love my N95. I wear it whenever I am indoors and not eating (& try eat outside most of
them time). It make my life more carefree, not less. I visited a friend w cancer. My mask let us visit. Later I saw another friend who was ill & it turned out to be Covid. Didn’t have to worry bc of my N95!
