Perhaps you saw the post series "Python is not a great language for data science"... well, here's Haskell IS a Great Language for Data Science https://jcarroll.com.au/2025/12/05/haskell-is-a-great-language-for-data-science/ #haskell :haskell: #rstats :rstats:

Great article that gives a quick run through of Hasktorch. www.stackbuilders.com/insights/has...

Article to checkpoint where we are with the Haskell Jupyter kernels. www.datahaskell.org/blog/2025/11...

There’s something beautiful at the end of all this. I just know it.

As cultural beings, we are echoes of the past: even our most personal thoughts, emotions, and experiences are mediated by words, images, and ideas we inherited from previous generations. Your mind was born and started growing many thousands of years before your body.” Francois Chollet

Wrote a new article where I checkpoint the work we’ve done so far enabling Kaggle style EDA-to-model workflows in Haskell. Covers Jupyter notebooks, dataframes, charting and machine learning with the iris dataset as the working example. mchav.github.io/iris-classif...

Lorem ipsum is taken from an excerpt about stoicism which says: “The wise man, therefore, always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains.”

Swiss insurer La Mobilière refactored their risk model to Polars, achieving 5-10x speedups and enabling actuaries to run millions of simulation years on laptops. A scale previously unfeasible with pandas due to memory and single-core limitations. pola.rs/posts/case-m...

The MIT program synthesis class finally has problem sets. I’ll dedicate most of the fall/winter to completing it. people.csail.mit.edu/asolar/Synth...

There are a lot of things I wish I had the discipline to learn over the years. I convinced myself I needed the right mentor or book. Years later, more has been lost from indecision than wrong decision.

“When a full-service grocer leaves a neighborhood, it doesn’t just take away a shopping option; it reshapes the local food landscape. Competition shrinks, which means prices rise and choices narrow. Families end up paying more whether they stay local or spend extra time and money traveling farther.”

Everything is converging to the same syntax.

Doing important things with AI is misguided. We use tasks to build context. That context begets creativity and problem solving in the future. Doing stuff is both a creational and transformative process. AI is faster but using it undercuts the most important investment you could make in your task.

Have some pretty cool examples of feature engineering using program synthesis on Haskell data frames. Give a function space, we run a breadth first search to find what functions (and their compositions) have the highest correlation with a target variable. github.com/mchav/datafr...

Starting a series on program synthesis: mchav.github.io/an-introduct...

Starting my foray into program synthesis and data wrangling. Currently trying to implement some interesting papers.

Considering deleting my LinkedIn. I’ve never liked the app and it’s kind of a cesspool.

I asked ChatGPT to roast me and it actually hurt my feelings. lol.

This was a pretty good side mission.

Are you looking to get started with Polars over the summer? We've partnered with @datacamp.bsky.social to create an interactive course that covers the fundamentals so you can write your next query with Polars. The course is free till the end of August: www.datacamp.com/courses/intr...

The mood is jubilant at Katie Wilson's primary election night party. Wilson is leading Harrell 46.2% to 44.8% in early results.

@diazcarrete.bsky.social is a wizard!

A Wild West Weekend is ridin' into central Puget Sound with full closures on SB I-405 in Kirkland, NB I-405 in Renton, SB SR 167 in Kent (all weekend) and SB I-5 at the Seattle Convention Center (overnight Fri to Sat). Giddy up. Check the details: wsdotblog.blogspot.com/2025/07/wild...

@fchollet.bsky.social was looking at your answer here around functional programming and deep learning. Not sure what the Keras API looked like then but it seems Keras pipelines look very "functional". Has your opinion on this changed? quorasessionwithfrancoischollet.quora.com/Have-you-eve...

We are happy to share more about what we are building and our goal to run Polars on any dataset size! A managed Distributed Polars compute cluster to ensure a single DataFrame API for all your needs. pola.rs/posts/polars...

Work is one of our deepest expressions of purpose and optimism. To work is to picture a future and gather all the faculties around you to realize that figure. That process itself is transformative.

Bernie Sanders is undefeated in inauguration shade.

If this inauguration speech (and the audience's reaction to it) is an actual trailer for what's to come in the next four years it's about to be a wild ride.

Some kind of revelation today in #Haskell. LazyByteString are actually a list of StrictByteString. So if you have a Stream of LazyByteString and you want a Stream of StrictByteString, do not use `Stream.map toStrict` but instead use `Stream.concat . Stream.map toChunks`. No allocations.

The age old lesson of post-colonial government: the person that shows you the truth needn't be the one to lead you to it.

Working on a dataframe library for Haskell. Honestly thought it would be straightforward but there are so many initial micro decisions whose impacts multiply profoundly as the code gets larger.
