Yinghua was a great scholar, but it is his smile I am missing the most.

Olivier De Groote @odegroote.bsky.social · Jun 17

And there it was!

Jacques Crémer @jcremer.bsky.social · Jun 9

and a few more questions about time format, multiple races, how I wanted the output displayed, styling etc., as well as whether a plain HTML/JavaScript app was fine.

Jacques Crémer @jcremer.bsky.social · Jun 9

It answered:
Great! Here are a few questions to help clarify your requirements and make the project more precise:
Input Method:
How do you want to input the start time and your arrival time? (e.g., manually via a form, reading from a file, using a button to "start" and "arrive", etc.)
Platform:
...

Jacques Crémer @jcremer.bsky.social · Jun 9

Here is what I asked. "I would like to build a small project that computes the time elapsed between the start of a race and my arrival. You can ask me questions to make is more precise."

Jacques Crémer @jcremer.bsky.social · Jun 9

The app computes the time between the start of a race and an arrival time. It is minimal but it is easy to enter the input.

Jacques Crémer @jcremer.bsky.social · Jun 9

This is unbelievable! I know nothing at all about programming. I downloaded Cursor. I gave it instructions in plain English; it asked for details and within five minutes (I swear) it had built a simple web app. I did no coding whatsoever.

@proffionasm.bsky.social has just published a compilation of her recent writing on Digital Platform Regulation, much of which is focused on European Regulation.
I am very honored to be a co-author on a few of the chapters.

I somehow missed this open letter from Lech Walesa when it first came out, following the Trump-Zelensky meeting in the White House... It's worth a read.

Do I understand correctly. Harvard corrupts the minds of its students. The Trump administration wants to protect international students from this corruption, while making it more accessible to American students?

The election of Cardinal Prevost as pope is prophetic. At the time where the US turns to "America First", the pope is an American who dedicated a major part of his life to serving another, poorer, country.

A lesson for all rich countries.

It seems that there is a distinct possibility that Musk has lost more through the decrease in Tesla stock than he saved the US government.

If they had thought this through, maybe they would have realized there was scope for a mutually beneficial trade.

Jacques Crémer @jcremer.bsky.social · Apr 17

I am sure there are important lessons here, but I am not sure what they are beyond the totally obvious (and useless) "be smarter and more strategic".

How China Took Over the World’s Rare Earths Industry

China seized mines and built factories. Japan took note and invested in Australia. But the United States did little despite concerns about control of supplies.

This has been a long standing problem. Already, in the 1st book of Samuel the Jews ask for a king despite the fact that God, through the mouth of Samuel, warns them against it!

How do I inform Bluesky's algorithm that one cute cat picture a week is plenty? And one 10s video a year.

Alissa belongs to our little "Yale" discussion group, and she is great. This is a very lucid explanation of the difference between regulation and lawsuits in the context of social media.

I am so smart 🧠! I have figured out the strategy behind the tariffs. They will indeed cut off the supply of fentanyl to the US:
the gangs will turn to more lucrative forms of smuggling, like Chinese plastic bath toys. 💡

Jacques Crémer @jcremer.bsky.social · Apr 9

I have not seen any discussion of the administrative difficulties of managing the tariffs.
I cannot believe that this is going to go well. Setting up all the reporting, collecting and policing mechanisms is a huge endeavor.
Imported goods will be more expensive, but also some will never arrive.

Jacques Crémer @jcremer.bsky.social · Apr 9

I know that the Trump administration cares only about trades in goods, but still, the US has a huge trade surplus in educational services, and they are killing it. 🤷‍♂️

Jacques Crémer @jcremer.bsky.social · Apr 8

It is an unfair trade practice for Chinese to produce American flags!?!?

Jacques Crémer @jcremer.bsky.social · Apr 7

On top of the many other idiocies involved, it never seems to occur to these people that the workers who will make the iPhones, or the steel, or... will have to be taken away from some other activity. What is it that they will not be producing?

Aaron Rupar @atrupar.com · Apr 6

Lutnick: "The army of millions and millions of human beings screwing in little screws to make iPhones -- that kind of thing is going to come to America."

Jacques Crémer @jcremer.bsky.social · Apr 6

As economist, I am flabbergasted by the self-harm inflicted on the US.
As a strong Americanophile, I am devastated by what MAGA ideology does to (and reveals about? ) the soul of America.

David Brooks is must reading on this last point.
