4-panel comic. (1) [Person with white hat talking to another person.] PERSON 1 with white hat: As Sherlock Holmes said, When you have eliminated the impossible, whatever remains, however improbable, must be the truth. (2) PERSON 2: What about the possibility that you forgot to eliminate a possibility? Or that you eliminated one incorrectly? Both of those remain, too. (3) PERSON 1: You’re being pedantic. It’s just a general rule for deduction. PERSON 2: But it’s a *bad rule*. (4) PERSON 2: How often have you thought, “I can’t find this thing, and I’ve searched the whole house. The only place I haven’t looked is the car, so it *must* be there.” PERSON 2: ...And then it’s never in the car. PERSON 1: *It’s never in the car!*

4.6 Billion Years On, the Sun Is Having a Moment In the past two years, without much notice, solar power has begun to truly transform the world’s energy system.

Globally, roughly a third more power is being generated from the sun this spring than last. If this exponential rate of growth can continue, we will soon live in a very different world, @billmckibben.bsky.social‬ writes.

How to Run an ESP32 Zephyr Application on Espressif’s QEMU - Shawn Hymel When working with embedded systems, especially platforms like Zephyr, it’s not always practical to rely on real hardware. Maybe your dev board is in the mail,

You can run #Zephyr applications on QEMU, which is great for early development, debugging, and #CICD workflows. Check out my tutorial for using Espressif’s QEMU fork for emulating #ESP32 applications made with Zephyr: shawnhymel.com/2807/how-to-... #embedded #programming

This is K2-18b.

It’s a planet outside of our solar system, about 2 1/2 times the size of earth, orbiting a small red dwarf star.

The James Webb space telescope spent time studying this planet via spectroscopy and determined it has gases in its atmosphere that are only created through biology!

In my case, there are 64 results that includes full copies of my textbooks. The ultimate irony was when others like OpenAI called out #DeepSeek for plagiarism!
