In 1969, Bob Widlar wrote an article for EEE, "Designing Positive Voltage Regulators", arguing that fully integrated voltage regulators were impossible. The reasoning: the pass transistor kills you: it gets too hot, varying the chip temperature, and there are no standard IC power packages.

I wish the airports affected by the ATC slowdown would say, “Commercial pax are the lifeblood of our business. In response to the slowdown, we are grounding all private planes.”

Congress told us to “Go Fund Yourself.”
And with your help, we can.
Our federal funding might be gone, but we’re still here. Public media needs your support now more than ever.

Hey Adobe, maybe a FOURTH pop-up will convince me to use your AI features when I am trying to read a PDF.
It can't be that I don't want it. Surely it must be that you haven't obscured enough of the screen with AI bullshit...

NPR and PBS are more than just Tiny Desk and Daniel Tiger. In rural areas across large swaths of the Western, Midwestern + Southeastern U.S., public broadcasters are often the sole source of information during public safety emergencies and weather disasters like wildfires, tornadoes, and hurricanes.

The White House has officially asked Congress to approve a rescission package — a rare and extreme measure taken with the broader goal of eliminating public media entirely. This would be devastating for local stations and the communities that depend on them. (1/2)

The Trump administration is trying to eliminate funding for public media, which would be a crippling blow for the millions who rely on our services, from our local newsroom to our children's programming that we produce for a national audience, to emergency support services that keep us all safe.
