Curious about I2C?
I’m having lots of fun building tiny projects using the Raspberry Pi, Pico, inexpensive breakouts and I2C. Here’s a great building block: an OLED display for the Pico W. I’ll share...

recent polling is just a total repudiation of the idea that full spectrum opposition to trump across every area was/is a bad idea
New NYT/Siena Poll:
—Trump's approval rating is 42% vs. 54% disapprove
—59% of voters think Trump's 2nd term in office is "scary"
—54% say Trump is "exceeding the powers available to him"
—Trump has negative approval in all policy areas

Today I asked Claude to create a FORTH VM. It wrote a lightweight implementation of the language for the Raspberry Pi Pico in Python, along with documentation, in about a minute.
The project is on GitHub, and there's a short demo video.

I'm feeling happily surprised this morning.
At 7 AM, over breakfast, my wife and I discussed our plans for the day. I told her what my main goal was. Using windsurf, an AI coding agent, I finished the job by 9 AM.

I've been using Codeium's cascade AI coding agent a lot recently. It's pretty good, so long as you keep it on a tight leash, but it's often meh at debugging.
Its "Ah, now I see the problem" is the equivalent of Baldrick's "I've got as cunning plan, my lord"

Some good news re H5N1…
A single dose of broadly nAb protects macaques from H5N1 flu. All the pre-treated animals survived, incurring very limited signs of disease vs controls developed severe or fatal illness. Protection from severe disease would last wks.
