Check out this 17th century coffee table book ordered by Ferdinando II de Medici to flex in front of his dukely friends

Tue, 24 Feb 2026 13:15:51 -0800

This portfolio / catalogue / manual / laboratory notebook came out of the first experimentally-oriented scientific society in Europe: 3 years before the Royal Society, 9 years before the French Academy.

A custom-designed chronometer.

“Saggi di naturali esperienze” is the first—and only—published work that came out of the short-lived Florentine Accademia del Cimento. The Academy was founded by the Medici family in 1657 with Grand Duke Ferdinand II and his brother Leopold as the first two members. I think it is fair to say that it started largely as a vanity project meant to produce a deliverable to spread the Grand Duke’s fame. Indeed, “Saggi…” was often gifted during embassies. However, it does not mean it was a front. The family definitely meant business from the get-go, allowing the academy to use the grand Palazzo Pitti for their headquarters and presentation spaces.

Fix for an override failure of nv-one-logger-pytorch-lightning-integration with Python 3.14

Fri, 13 Feb 2026 19:17:18 -0800

This should be a GitHub issue on https://github.com/NVIDIA/nv-one-logger/blob/main/nv_one_logger/one_logger_pytorch_lightning_integration/src/nv_one_logger/training_telemetry/integration/pytorch_lightning.py but Nvidia is not interested. So, for posterity and my own future self, I’ll put it here.

(PS: Just kidding, this is probably one of the third parties being a bit overzealous.)

To replicate, run the following

import nemo
print(nemo.__version__)

import nemo.collections.asr as nemo_asr
print([model for model in dir(nemo_asr.models) if model.endswith("Model")])

to get:

Ted McCormick. “William Petty and the Ambitions of Political Arithmetic”. New York: Oxford University Press. 2009. Pp. 347. $99.00.

Ted McCormick’s book is a valuable reassessment of William Petty’s intellectual legacy. Although, since it was the first and remains one of the few contemporary monographs dedicated to Cromwell’s physician and Charles II’s man in Ireland, perhaps it would be more accurate to call it a vital introduction. It takes a step back from the fragmentary reception in modern social sciences of Petty’s political arithmetic— largely based on Charles Henry Hull’s 1899 edition of his selected papers—where it is commonly associated with what we would now call econometrics. Instead of treating his work as a mere foreshadowing of the modern drive to turn economics into a quantitative science, McCormick makes the effort to reconstruct his hero’s intellectual journey in a proper historical manner. That is, he inquires as to how it might have unfolded in the mind of a driven early modern Englishman with scholarly interests, artisan’s means, and vast ambitions. The picture thus painted was, admittedly, a lot more interesting, albeit less favorable to Petty.

Although the gender of a witch in early modern Europe was predominantly female, a not insignificant minority of accusations made during witch hunts was directed against men. According to some estimates, male witches might have constituted on average up to a quarter of all the recorded defendants, however regional proportions varied dramatically, from 5% up to 92%.¹ Gender-based explanations of motivations behind witch hunts abound in the literature, with more nuanced modern approaches highlighting the role of status entangled with gender in specific cases.² Nonetheless, the mechanisms at play in mostly male witcher hunts remain largely unexplained. This volume, edited by Alison Rowlands, contributes to filling in that gap in literature.

Making YouTube usable again

Tue, 26 Aug 2025 14:08:46 -0700

Like most of us, I have a love/hate relationship with YouTube. It clearly takes far too much of my time. However, there is also a bunch of people I respect who publish video-essays and deep-dives (code-, research- and writing-related), and that is the only place to hear them talk. Also, there are the videos your family really needs you to watch or the sky will come crashing down. So, I end up manually activating dirty CSS injections on several devices and across multiple web browsers just to block suggestions, shorts, the “For You” section, comments, etc. to make sure I do not fall into the rabbit hole, having watched the thing I actually cared about.
