    Every week I am reminded that I once quipped: "The great thing about starting your own business is that you will learn *so many things*. The only problem is that these will all be things you never wanted to learn." - perhaps I have never spoken truer words.

    okay. im gonna rant about being a woman in our healthcare system. if it’s not your jam, please skip— I don’t have the energy to argue about this. i’m BRCA2, which puts me at extremely high risk of breast cancer (87%). to mitigate my risk, I chose to get a preventative mastectomy

    After a few hours, I have LUI and BEQ working and can use gtkwave to see register values flip-flopping back and forth in my hand assembled 3-instruction loop.

    Inspired by ’s YouTube series implementing a Motorola 68k CPU in nMigen, I’ve started playing around with implementing a RISC-V RV32I CPU in nMigen.

    Over the holidays I had a slight accident. The wait times were: Emerg: 30 min (Xmas Eve) Surgery: same night Follow up X-ray: 20 min Surgical consult: 10 min 2nd surgery: same morning Cdn healthcare system deserves some criticism but it’s there when you need it. And it’s free.

    I wasn't poor, black, nor homeless, but had some similar feels as a mixed immigrant trying to navigate the US education system. My parents had no idea; they were surprised anything besides grades was needed.
