Incredible spot of #TheStarBuilders in the wild by a friend—and the furthest yet! As seen in the Maruzen bookshop, Kyoto.
But if you have friends in Japan, you can also now buy them the new translation (second photo) ❤️🇯🇵💫

Well, thanks to a great tip off by @simonwillison.net I'm exploring the rarely-open London Transport Museum Depot. And it's great! Underground trains and buses and other transport paraphernalia from the late 19th century up to the modern day.

You hear a lot of people claiming that Nigel Farage gets an undue amount of coverage given the number of MPs in his Reform UK party.
I wondered if that was true, so I ran a query against GDELT, which monitors mentions of specific people across broadcast, print, and web news.
And.... it is!

Great evening launching this year's No10 Innovation Fellowship @designmuseum.bsky.social! It was incredible to meet so many talented people enthused about doing the hard yards needed to make the public sector even better. The appetite for reforms and improvements was genuinely very inspiring.

So Mac and Linux will work just fine with that but for true cross platform you'll need to wrap it in "Path" like this example:

When I moved to London, I had always imagined I would be going to glamorous book launches and gallery openings (thanks to Sex & The City and Bridget Jones' Diary)
Tonight I got to go to the launch of the excellent #Ignite written by my friend & colleague Neeltje!
Self-help but backed by science 🤩

There's lots of chat about how AI could help public services be delivered more efficiently right now—& I've got a new pre-print out looking at part of this: how data science can help policymakers cut through complexity & deliver better services! 🧵

Here are the results with gemini-exp-1206 (h/t @tussles-shriek.bsky.social). It seems like it's better at latex equations but has omitted any markdown formatting. Both have a couple of mistakes that would likely resolve with a better photo + better prompt. Impressed!

With thanks to @simonwillison.net, @martinapugliese.bsky.social, and @tussles-shriek.bsky.social I've got a small example of handwritten lecture notes to markdown working with gpt-4o.
Not perfect, but my starting pic was terrible; the results are impressive given that!

Really? And best to let your friends use what suits them best IMO.

I just released Coding for Economists v1.0.2. This update fixes a lot of minor issues and switches to Astral's uv as the recommended package manager. We have some new contributors too. And, big news, CfE also hit 750 stars! ⭐⭐⭐

To @ox.ac.uk today to visit the mathematics institute and catch up with collaborators on how to improve nowcasting models and make them resilient to difficult data and crisis periods (think Covid times.)
Was delighted to see the Penrose tilings outside and the inside is like an Escher!

Visual summary table's even work when an executed notebook is exported to markdown! And you can export statistics in a table as a (vector) graphic or as a Python dictionary—extremely handy for any onward use of the aggregations. It works across all major OSs too.

Skimpy is a free and open source Python package that produces a visual statistical summary of data in Python consoles, Jupyter notebooks, and terminals. It produces summary stats for continuous numbers, integers, strings, datetimes, dates, time differences, booleans, and categoricals.

Well, it finally happened... Skimpy has hit 400 stars on GitHub!
Thanks to everyone who has been using it and has helped make it better.
Not sure what Skimpy is? Then read on!

Back in August 2023, I launched Python for Data Science, a free book that pretty closely follows R for Data Science. Today, I'm celebrating that Py4DS has hit 118 🌟 on GitHub!
Thanks for all the support & additions!

The first commit was in Nov 2020 (!), it's racked
up 581 github ⭐️s, and it's currently getting 4k users / month, so I would say this is long overdue, but I've finally done a version 1.0.0 of Coding for Economists!
