A modified version of a tool called Bjorn, based on a tool Pwnagotchi. It's an offensive network intrusion testing tool with a little character that gains skills and levels up

As a technical experiment, I wired this little hacker to a local language model and it found one vulnerability in a raspberry pi I misconfigured. From there it was able to reach everything on my network

Level 20 though!

EU: The European Union will require sale of mobile phones with “user-replaceable and longer-lasting batteries” starting in 2027.

The regulation demands “availability of spare parts and manuals for 10 years to curb planned obsolescence”.

DOJ demanded voter files from all 50 states.

DOJ sued 31 states for refusing their demand.

My law firm intervened to protect voters in those cases.

DOJ is now 0-5.

My firm is 5-0.

Lesson: When we fight we win.

Anne Hathaway bought the rights to a novel about a tradwife influencer who wakes up in 1855 and has to actually live the life she's been selling online. The book is called Yesteryear. It came out 3 days ago. The film rights were already sold to Hathaway, who will produce and star.

Solderless breadboard with Teensy 4.1 having an SD card and 3 more SD card adaptor boards, connected to many wires to Teensy 4.1 pins.

Solderless breadboard with Teensy 4.1 having an SD card and 3 more SD card adaptor boards, connected to many wires to Teensy 4.1 pins.

It's not a frequently asked question, but does come up occasionally, how to connect multiple SD cards. Starting today, Teensy's SD library has a 4 SD card example.

The extension makes it really easy to get precise inside measurements. You can duplicate without reading the numbers like your tool. A tape ruler can work for inside measures. You have to add the size of the case to the number. Or lock the tape to duplicate the length.

Good tools cost more. Cheap tools sell more. I'd guess carpenters use tape rulers more often because of $ and speed. Unlike woodworkers, most carpenters don't need precision. The folding rulers are easier to break when working fast.

Not sure. Mine is 40+ years old. Checking local store (New York) for prices
Folding rule + extension = $42
Folding ruler w/o extension = $15-$20
Tape rulers= $8-$230
