before diving into agentic AI coding, learn git. Version control becomes even more critical when you need to undo what the AI did. (And no, letting the AI manage versioning is not the answer.)

"Third, Europe actually can defend itself and resorting to scare figures such as Rutte’s 10% of GDP, is nonsense. Russia, the most obvious security threat to European states, has a GDP that is less than 10% of just the EU’s. If you add the UK and Norway to the mix, Russia shrinks in comparison."

sorry i made that up.

Time to call things by their name. A thug is a thug. And the boss is the boss.

interesting paper: Vibe Coding Kills Open Source Software.

#EconSky #DataEditorTips Your results should replicate each time you submit your paper, not only *after* it was accepted. Having your package replicable all the times is going to buy you a lot of time and-more importantly-peace of mind. What if you cannot replicate a result in the accepted version?

I forgot how painful MS word and rich text format are. Please, funding agencies, give us templates in formats suitable for scientific writing. just wanted to insert a 2x2 grid of equally sized figures with referenced captions. Totally impossibly hard to achieve. Not to talk about citations. d'oh...

It’s just delirious. None of this makes any sense.

When Elon changed the name of Twitter to X everyone was like "what the fuck, that sounds like the name of a website for extremely illegal pornography made by and for nazis" And behold what it became. Nominative determinism go ew

Yeah, I was right in the middle of it. And yeah, the whole “dark fiber” thing was a wonder to behold. Now we have “dark GPUs” that will be obsolete by the time the data centers are built, which are waiting for the power and water infra. Yeah lots of companies are going to die.

How to deal with 17GB dataset on a 16GB RAM laptop? my updated version of Grant's @gmcd.bsky.social big data workshop from 2 years ago. That's where I first saw @duckdb.org and never looked back. interfaces in #rstats #julialang #python floswald.github.io/duckdb-polars/

[…] in his conversation with the Times, Trump said, “I don’t need international law.” When asked if there were any limits on his powers on the world stage, Trump said: “Yeah, there is one thing. My own morality. My own mind.”

“These findings provide clear evidence that data collected on MTurk simply cannot be trusted.”

on.ft.com/445lKl9 Trump’s world view: cynical, self-interested and money-grabbing

Hi all, please spread the word and we hope everyone can make good use of this new data drop: cmfdata.org The full surviving establishment-level Census of Manufactures manuscripts and digitized data from 1850, 1860, 1870, and 1880!

let them eat toilets.

Things are not looking great. How on earth is this possible?

And so it begins, Musk's Grokipedia is scraping Wikipedia and re-writing things in Musk's image. The entry for climate change? Let's just say the Wikipedia entry has neither an "Economic and Policy Critiques" section, nor one on the "Role of Media and Advocacy" that accuses both of bias.

The @python.org foundation is fundamental in maintaining python. Y'all are waiting for the huge benefits of AI to materialize? Good luck without a working python ecosystem. Trump has cut funding, because they are here for everyone ("diverse and international"). You can chip in, 25$/year. #econsky

Look, I dont care about about your accent or limited vocabulary in English. But the Spanish Erasmus student standing in front of me, punching Spanish sentences into her phone, so that she can “talk” to me is one step too far. You must speak basic English. It’s embarrassing.

The amount is meaningless — less than one day of salary. But the principle is important: once the armed services are paid by the oligarchs, they become a private militia, and we no longer have a country. www.nytimes.com/live/2025/10...

Trump doesn’t like climate change, so he just stops funding climate research. Great explainer by FT what this means. Obviously not smart to fly without any data through the haze in general, but even short term outcomes (weather forecasts, insurance premia etc) are under threat. on.ft.com/4nZI1II
