#Transistors. How do they work?

I need to make a switch which has LOTS of resistance when off, but *little* when on. How can I thread that needle?

MOSFETs have great on resistance, but they leak a bit much current. I need <1µA.

Bipolars don't leak a lot, but they also don't conduct enough.

Both parameters eat into the same property of my circuit from different directions.

HELP!

I blogged about the fediverse. A short (hopefully non-technical) overview to send to my non-fedi friends and colleagues:

A resident of Washington State has died from H5N5, a variant of bird flu never before seen in humans.

First known case, first death.

Wear a mask, ideally a well fitted respirator like an N95.

RFK Jr has gutted the CDC.

There’s no plan to deal with another pandemic.

No one is coming to save you.

Masking is an act of resistance and radical community care.

Another immigrant has gone missing from ICE custody after suffering a medical emergency and losing consciousness.

ICE enforcement is a mass disabling event

If you have a medical emergency in ICE custody, there’s a chance you will simply “disappear”

Or you could end up like Randall Alberto Gamboa Esquivel who was deported to Costa Rica in a persistent vegetative state.

He died soon after

Post: Still We Rise @_stillwerise

AOC: “MTG is carefully timing her departure just 1-2 days after her pension kicks in and after making millions of dollars insider trading stocks for weapons manufacturers and others while in office. She is saying a lot but her ACTIONS have
not backed up the rhetoric. For all her talk, she's STILL voting with them to gut healthcare and advance self-dealing corruption schemes.”

Pro tip: on Black Friday, all of your favorite Linux distributions will be FREE to download.

I made a tally of the total planned AI data centre capacity in Scotland and I am a bit shocked: it amounts to 7.3 GW, which is as much as the entire energy consumption of Scotland, electricity + gas in 2023.

To spend as much energy on "AI" as the entire need of a country is madness. And I have no doubt that this picture would scale if I did it for the entire UK etc.

If any San Francisco Bay Area folks in my feed find themselves in the North Bay this weekend, on Saturday I’m going to be giving a live, hands-on, interactive weaving demonstration at Fiber Circle Studio in Petaluma. Drop by and I’ll show you how to make fabric by hand! #weaving

Yup, cats, and their wandering predatory ways, are a huge problem, and getting much bigger: rnz.co.nz/news/in-depth/579669 they need to be desexed, restricted to the owners property, and kept inside at night.

VICTORY! EFF’s clients just ended a dragnet government surveillance program that spied on Sacramento residents’ electricity data. eff.org/deeplinks/2025/11/vict

An employee well being survey indicates rollback of pandemic era flexible working conditions (RTO) and increased productivity demands have driven well being scores of workers down while managers report higher well being. Technology, healthcare and education show these trends the most.

I bet 2025 employee well-being scores will make 2024 look like a vacation in comparison given how much layoffs and AI replacement talk has ramped up.
