Congress passed the Taft-Hartley Act in 1947 (over Truman's veto) to make general strikes so incredibly difficult to organize that there hasn't been one since.

That there is a general strike happening in a major US city on such short notice is nothing short of a miracle.

I can’t believe that UNL would need to cut four dept and merge other programs just to save 27M! Their operating budget is a billion dollars. They could have just asked every dept/office/program to cut 2.7%!

I found some discrepancies in the results produced by code that I recently wrote and code that I wrote 10-15 years ago. So it's a me vs me situation, and I'm not sure who to trust! 😆

When was the last time they updated their base R? Could they be trying to run RStudio with a very old version of R?

Their waists and hands were tied together, forcing them to bend down and lick water to drink. The unscreened bathrooms contained only a single sheet to cover their lower bodies. Sunlight barely penetrated through a fist-sized hole, and they were only allowed access to the small yard for two hours. Detained by US immigration authorities for eight days, the workers and their families expressed shock, describing human rights violations and absurdities they could not have imagined as ordinary Koreans living in 2025.

I was on a zoom call where an LLM trained on ChatGPT4 accepted an arithmetic error. It was a sum of 4 numbers. Correct answer was 60, and it accepted an answer of 61. 🙃
Keep using your calculators, folks!

Help appreciated! I'm looking for an education journal that publishes illustrations of statistical methods. It could be teaching corner for education researchers. It could be a case study.
Methods are not new, but we discuss algorithmic bias in education. Any ideas?

You know the joy of a canceled meeting? It is far overshadowed by a scheduled day-long meeting that was advertised as ending at 2pm to still be going on at 3pm with no end in sight. 😫

🧪 PRACTICAL tip for NSF PIs with terminated grants:

You're entitled to recover more closeout costs than a DOGE-fueled NSF may lead you to believe.

➡️ Do this NOW: Send fed reg 2 CFR 200.472 on allowable "termination costs" to your sponsored research office:

Just had a grant canceled. It longer aligns with agency priorities. Know what it aligns with? The agencies priorities when we wrote and were awarded the grant!

I didn’t know I needed a time machine to do science.

🙏 We need your help 🙏

The government continues to cancel grants at both NIH and NSF to censor science it doesn't like.

We're tracking terminations to organize and advocate. Please report your terminated grants:
