First attempt at spring rolls turned out ok.

Major blackberry removal today. All the fresh dirt in the photo had 4' tall blackberries. 60" brush mower and loader with tooth bar made all that a 4h job.

Oops. We accidentally discovered a vulnerability in NXP LPC55 microcontrollers. https://oxide.computer/blog/lpc55/

Made test rafters for the playhouse today. Tried 6/12 and 9/12 pitches. Thinking 9/12 looks better.

I hear scurrying in my ceiling.

Rain let up early this morning so today was a perfect day to grade a site for the playhouse and lay a foundation.

Lab storage is a little bit more organized.

Building a playhouse with the kids. Might unintentionally be building a tiny house instead.

Love designing dense PCBs filled with high-speed buses? Apply at Oxide! No, really, we need another EE. Boards are being designed by software engineers.

Which file formats and options does _this_ assembly want me to submit my design in? Gerber, Excellon in inches, Excel BOM, XY w/ bottom left origin and positive axes, readme.txt to explain what each file is. 😭🤯💩

Is sprinkling bypass caps near layer changes an effective way to avoid doing more SI analysis? Asking for a friend. (not really asking)

Do I run the 2xRG6+2xCat5 I already have throughout the house or do I buy a bunch of Cat6?

RISC-V emulator for 8051. Such a beautiful hack. https://GitHub.com/cyrozap/rv51

Refusing to communicate with your coparent is a terrible parenting strategy.

Firmly into negative spoons territory tonight.

Situation: cozy

Not going to finish with this tree today

I'm at that point in my career where people buying computers from their formative years are buying machines I worked on.
