Rosa Parks Birthday, 2026 #BlackHistoryMonth #RosaParksDay
Happy Rosa Parks Day! There are a few different days to celebrate #RosaParksDay. December 1st commemorates the anniversary of her arrest in 1955, and many locations observe the Monday after her birthday. Today, though, would have marked what would have been Rosa Park’s 113 birthday.

Learn more about Rosa Parks, her experiences on the bus in Montgomery, Alabama, and her role in the Civil Rights movement. Discover how the Montgomery Bus Boycott affected the bussing system. Several books and films offer insight to this day in history and the Civil Rights movement to follow.
- Quiet Strength: The Faith, the Hope, and the Heart of a Woman Who Changed a Nation by Gregory J. Reed and Rosa Parks
- Rosa Parks by Rosa Parks
- She Would Not Be Moved by Herbert R. Kohl

Rosa Parks and the Montgomery Bus Boycott via PBS:
This interview with civil rights activist Rosa Parks describes her role in the Montgomery Bus Boycott. On December 1, 1955, Parks refused to give up her seat to a white man on a bus in Montgomery, Alabama. Her refusal sparked a massive bus boycott that lasted 381 days, ending on December 21, 1956, after the United States Supreme Court ruled that racial segregation on city buses was unconstitutional.

The TMP119 is the most precise-iest temperature sensor ever? 🌡️
New year, new proto! We’re getting our pants on (metaphorically) and here’s a first new proto to kick things off 
The TMP119 has ±0.03°C (typical) accuracy from 0°C to 45°C…that’s wild precision for a little breakout board. It’s very much like our existing TMP117, so we just tweaked the PCB for this teeny DSBGA-8 footprint.
We’re going to see how hard it is to pick & place this tiny part, but it was requested and it looks pretty nifty! As always, it’s got our Stemma QT connectors on board for easy I2C daisy-chaining.

Raytracing on the Sega Saturn #CanItDoRaytracing
While modern consoles chug at the thought of raytracing, YouTuber XL2 demonstrates how they pulled it off on the Sega Saturn, a console over three decades old. More from Gizmodo:
But wait, what is raytracing, and why’s it so difficult to implement? In the most basic sense, it’s one of the ways by which a computer can work out how objects in a three-dimensional scene are lit. In real life, light bounces around a scene, with different surfaces and materials absorbing, reflecting and/or scattering different amounts of light. Raytracing works by simulating this process, with the renderer tracing the path of a number of rays emitted by the scene’s camera through a given number of bounces to see if they intersect a light source. (In real life, of course, the rays go from light source to camera, but in a renderer it’s more efficient to trace them in the opposite direction.)
XL2 (Sega Saturn homebrew) Raytracing test:
The room you see has no static light, but the raytracing could be used for adding dynamic raytraced lights on top of the static light sources. I only update 1/4 the vertices per frame. When a vertex fails the test, I smoothly darken it back to 0. When it passes, it goes full bright right away. I don’t do any fancy tests right now for the light (like using the surface’s normal or the light’s distance), so it could look better with a bit more maths. Now, for indirect lights : I do keep a per face PVS of what face affects what other faces. I just need to find a way to integrate it a reasonable speed on the Saturn.
Until someone cracks raytracing on the Fruit Jam you can still enjoy some DOOM.

Professor Sarah Chasins Answers Coding Questions
UC Berkeley Computer Science Professor Sarah Chasins joins WIRED to discuss coding.
UC Berkeley Computer Science Professor Sarah Chasins joins WIRED to answer the internet’s burning questions about coding. How did programmers code the first ever code? What remnants of the early World Wide Web still exist online? Can someone still learn programming if they hate math? How do new programming languages get made? Why is debugging harder than writing code? How can computer scientists contribute to CRISPR?

Macalda di Scaletta one of the earliest female chess players
Macalda di Scaletta was a Sicilian baroness in the 13th century who played chess and historical evidence suggests that she may have been the first person in Sicily who learned how to play it the game, Via Wikipedia
Macalda’s captivity allowed another of her unexpected qualities to be revealed, that of chess player: we know in fact that, during her imprisonment in the Matagrifone castle of Messina, Macalda entertained herself at the game of chess with the Emir of Djerba, Margam ibn Sebir, who was also held in prison after being captured fleeing to Tunis while trying to escape the naval incursion on the island of Djerba by the admiral Roger of Lauria.
Also in these encounters, the haughty Macalda did not fail to astonish the bystanders and her jailers with the sensation caused by her “vivacity and the immodesty of her garments” that she flaunted.
Historical evidence suggests that she was probably the first person in Sicily who learned how to play chess.[1] It would in fact take another two and a half centuries, until the time of the Holy Roman Emperor Charles V of Habsburg, to have the first three historical mentions by Pietro Carrera of Sicilian chess players: the Palermitans Armini and Branci, and Don Matteoli Genchi of Termine, author of some stanzas on the rules of chess play.

RadioShack Sold You an “AI” Therapist in 1979
RS-80 Manual: Eliza (1979)(Tandy) – archive.org
Before ChatGPT, before Siri, before Clippy annoyed you about writing a letter — there was ELIZA, and you could buy her at the mall.
In 1979, RadioShack released “The Amazing Artificial Intelligence Simulation” for the TRS-80 (catalog no. 26-1908). For the price of a few cassette tapes, you got a port of Joseph Weizenbaum’s 1966 MIT experiment: a program that pretended to be a Rogerian psychotherapist by turning your statements into questions.
“I feel sad.” → “Why do you feel sad?”
It was a parlor trick. Weizenbaum knew it. He built ELIZA specifically to show how shallow the illusion of understanding could be. Then he watched in horror as people poured their hearts out to it anyway.
RadioShack, never ones to miss a buck, packaged that existential crisis in a three-ring binder and sold it next to the battery display. Forty-five years later, we’re still having some of the same conversations — but with better graphics and venture capital. The big difference, for some… the machine is the problem, for others, it tells them their problems, either way there is a monthly fee.

🕰️Time Tellers of The Adafruit Learning System🕰️ – Build a Clock Today
The Adafruit Learning System is full of projects to keep you organized and on-time. These are a few excellent clock builds you can try right now:
Network Connected RGB Matrix Clock
The METRO Matrix Clock displays the time in the IBM Plex mono typeface, using a neon green hue for daytime hours, and red for nighttime hours.
Metro Minimalist Clock
This Metro Mini microcontroller-based clock is a minimalist timepiece that celebrates, rather than hides, its components. It’s a straightforward build, electronically, and it’s up to you to house and display it any way you like!
LED Matrix Alarm Clock
This LED matrix alarm clock is inspired by the cute plush toy monsters LaBuBu by Pop Mart. The clock is powered by an Adafruit QT Py ESP32-S3 with an amplifier for high quality audio output.
Cartoon Character Clock
The GC9A01A round displays are perfect for displaying a clock face. This fun clock uses the Display Analog Clock library along with some customized assets inspired by an early 20th-century public domain cartoon.
Digital Clock with CircuitPython
A digital clock with a large 7-segment display, a Feather RP2040, and CircuitPython — no internet required! For time keeping, this build uses the DS3231 Real Time Clock module for precise and accurate timing.
Qualia S3 Space Clock
With this project, you can easily switch between viewing your local time on Earth and coordinated Mars time (MTC) on a beautiful round 720×720 display housed in a retro space-themed orb enclosure.

Black History Month 2026
Black History Month 2026 starts today! Throughout February, check out the blog for stories celebrating Black history and the incredible contributions of Black makers, scientists, artists, hackers, and more.
The Theme for 2026 is A Century of Black History Commemorations
From ASALH:
2026 marks a century of national commemorations of Black history. Dr. Carter Godwin Woodson, George Cleveland Hall, William B. Hartgrove, Jesse E. Moorland, Alexander L. Jackson, and James E. Stamps institutionalized the teaching, study, dissemination, and commemoration of Black history when they founded the Association for the Study of Negro Life and History (ASNLH) on September 9, 1915.
