Those Blinking LEDs on Your Raspberry Pi Have Special Meanings

Raspberry Pi’s status LEDs are a surprisingly powerful diagnostic tool, especially for headless setups.

Threat actors have been distributing trojanized versions of the KeePass password manager for at least eight months to install Cobalt Strike beacons, steal credentials, and ultimately, deploy ransomware on the breached network.

"Protest Starter Pack: Creators and Allies unite, stand up and fight!

★ All major AI generators are trained on stolen content. That’s unethical and unfair.
★ They’re built to deskill and replace human creators. With their own work.
★ AI users support theft, data laundering and broligarchy. Don’t feed the bullies!
★ It’s not “just” artists. They steal your data as well, and will replace your job too.
★ We need consent, compensation and transparency. It’s called Opt-In.
★ AI enables fraud & destroys the web with false facts. Stop the slop!
★ If it’s in the training data, AI reproduces bias, stereotypes and prejudice.
★ Care about the climate? Stop AI wasting the resources of our planet!
★ It is not “time to adapt or die”. It is time to fight – or adapt and die.
★ So let’s unite, petition, protect, inform, explain and call out! Together, we are strong.
★ Thank you for fighting unethical generative AI! Or at least not supporting it.

Artists fight against generative AI, which – unlike technical or scientific AI – is trained on copyrighted and private data without consent or compensation, and used commercially, in unfair competition with our own work."

Just finished sewing a new sling bag with a 32x18 LED matrix inside the pocket flap. The pocket flap snaps off so the matrix can be used in other designs. The controller and battery fit nicely inside the front pocket

If anyone is an RPI user, I'm fixing my various display and imaging libraries to work correctly on Arduino and RPI (the same code). In the photo is my JPEGDEC running on a rpi400 with a Pi TFT ILI9341 attached.

I rarely use web components but this site makes a pretty convincing case that many frameworks (js and css) and build tools aren't necessary using more modern syntax, including web components.
Obs it won't work for some teams (and group momentum is real) but it might be worth a look if you're starting something new.

Monopoly wasn't invented by the Parker Brothers, nor the man they gave it credit for. In 1904, Monopoly was originally called The Landlord's Game, and was invented by a radical woman. Elizabeth Magie's original game had not one, but two sets of rules to choose from.
One was called "Prosperity", where every player won money anytime another gained a property. And the game was won by everyone playing only when the person with the least doubled their resources. A game of collaboration and social good.
The second set of rules was called "Monopoly", where players succeeded by taking properties and rent from those with less luck rolling the dice. The winner was the person who used their power to eliminate everyone else.
Magie's mission was to teach us how different we feel when playing Prosperity vs Monopoly, hoping that it would one day change national policies.
When the Parker Bros adopted the game, they erased the "Prosperity" rules and celebrated "Monopoly".

The circuit modelled in the #Tinkercad activities is our ARPS-2 shield for #Arduino UNO.

Use ARPS-2 to learn beginner programming and build a simple #robot! Find out more: mirobo.tech/arps

Front view of a simple robot constructed on a white wooden base. The robot is controlled by an Arduino UNO with an ARPS-2 shield mounted on top. A SONAR module is plugged into ARPS-2, and two optical floor sensor modules have been snapped off ARPS-2, mounted on the wooden base, and connected to ARPS-2 using short extension cables. The robot is propelled by two inexpensive yellow gear motors connected to yellow and black wheels, and powered by AA batteries (not shown) that would be installed in a battery holder at the back.Rear side view of a simple robot constructed on a white wooden base.

@scruss Probably Durham then. Yeah, the kids definitely couldn’t hand in easily found Arduino code when they were programming PICs! 🤣
