An alternative to good (not really) 'ol Jupyter Notebooks.
Looks promising. First of all, they solve the biggest Jupyter problem: stateful execution and thus dependence on the order of cell evaluation. The problem is so large they trained ML models to predict the correct evaluation order. I kid you not.
The solution is pretty common and straightforward: upon loading a file, build the Dataflow Graph, then re-run all the transitive dependencies upon a cell change. This also gives you the "reactive programming for free".
Reactive updates also give you a reactive UI (almost for free). Demos look pretty nice and useful:

And while we're at it, yeah they have a Web playground, and can convert notebooks into Web pages (also slides) out-of-the-box. Moreover, they can produce dynamic Web pages without a server employing WebAssembly. I haven't tried it, but if it works well, that's immensely useful.
Among other things, they store notebooks as valid Python files, which provides integration with Git and many other tools for free. They also integrate with package managers, especially
Additionally, they support DuckDB for running SQL queries, including on DataFrames. And implement nice UI to view, filter and summarize the results.
Overall, feels like a cool and handy, batteries included tool, alleviating a lot of Jupyter Notebooks quirks and letting you get your crap done quicker.

VS Code now has "AI settings search".
Yep, that's right, they use a freaking LLM to search in a code editor settings.
And they showcase in the release notes an example search for "increase text size" that returns font size settings. Are you sure that's a meaningful example? Do we really need an LLM to discover font size settings?
At any rate, did you consider simplifying freaking settings before implementing a LLM search through them?

Douglas Crockford gave a sorta first-hand overview of the (arrested) development of Programming Paradigms and was promoting the Actor Model as the way forward.
His only complaint about Erlang was that the addresses of the actors/processes are guessable, and thus do not provide the desired security level. Yeah, everything else about Erlang/Elixir is great. 😊

"Incremental query updating in adhesive categories"
And they freaking deliver on that promise!
That might not completely solve the problem of Differential Dataflow, especially in the case of SQL queries — I suspect the queries and/or updates don't have the right shape in these cases. But even solving incremental https://egraphs.org/ is a huge boon for a lot of domains.
"Incremental query updating in adhesive categories"
Working in the general setting of adhesive categories, we derive a practical algorithm for incrementally updating a query’s results with respect to small changes in the object being queried.
How can we unify and automate the intuition of the above examples, in the form of an algorithm that is a couple of lines long and self-evidently correct?

A Web page says:
Get in touch with us to learn more about our mission and work, donate to our cause, or to become involved yourself. The best way to do this is by sending us an email:
info [at] topos [dot] institute
You can also find us on the following sites:
To what email should I write to reach them?
You should write to info [at] topos [dot] institute.
The page specifically instructs you to use that email address. The "[at]" and "[dot]" are used to prevent bots from automatically harvesting the email address. It means:
[at] should be replaced with the "@" symbol.
[dot] should be replaced with the "." symbol.
So, the full email address is [email protected].

Among the few advantages of attaining the dizzy age of 70 is the ability to look back on half a century. Things were great back in 1975. ... Great progress had been made in Artificial Intelligence, thanks to a relentless focus on symbol processing as opposed to discredited, useless neural networks. Many thought that automatic theorem provers could lead the way to what we now call AGI. Also, watches did not have operating systems. People knew that clouds were real and that vaccines worked. Well, a lot can happen in 50 years.

Elias Bareinboim published a "draft" (comprising 1200 pages!) of his "Causal Artificial Intelligence" #book for #free.
Bareinboim spent years connecting Causal and Counterfactual Reasoning and #causalinference following Judea Pearl with Machine Learning and Reinforcement Learning in particular. So the book tells it all: from the fundamentals of Structured Causal Models (with infamous backdoors, frontdoors and d-separation) to Causal Reinforcement Learning to Neural Causal Models and "Causal GenAI" and beyond.
If you understandably don't have the time to read through the volume front to back, Bareinboim published most of the slides for his lectures following the book, and the rest are coming.

The live stream is publicly available, but buying this ticket helps pay for the live stream and ensure its availability for the entire community.

Active Statistics by Andrew Gelman and Aki Vehtari
A #free introductory #book to (Applied) Statistics from some of the best teachers and practitioners of the craft alive. And that's not all what's great about it.
The book is unusual in that it's aimed at (university) teachers. And thus the material is split between two semester and weekly classes, while the first part explains the pedagogy of the book: the "flipped classroom" approach, the role of computation and simulation, setting up assessment, and so on.
The classes themselves are centered around "stories", which are supported by relevant activities for the students, computer demonstrations and open-ended questions to discuss.
Gelman was deeply thinking about what makes a good educational "story", and gave a couple of talks summarizing his conclusions and approach. Thus the stories in the book are far from random and purely entertaining anecdotes. They capture the essence of the topic and provide the bridge between more abstract statistical notions and techniques and the real-world applications.
While invaluable for teachers, the book is highly applicable for self-study or study group, as soon as you become your own teacher and can leverage the structure, examples and exercises.
