This week, Tim Cook and I have both announced that we’re leaving Apple. Not to brag, but during our tenure, we have added a combined $3.5 billion worth of value to the company.

A fortune cookie message that reads, “A bold and daring adventure is in your future.” Also, in the background blur text of a message can be seen to read, “To whom it may concern, I would like to resign from Apple on May 1, 2026. I have greatly appreciated and learned much from my time at Apple, but it is time for me to move on. Sincerely, Mach Kobayashi”.

A very apropos fortune cookie message…

Open Brush Open source painting in XR!

I was once part of a small team at Google that made a VR drawing app. Today is the ten year anniversary of its release. Happy birthday, Tilt Brush! The app is no longer supported, but it lives on in openbrush.app @openbrush.app

A tiny souvenir from the moon! YouTube video by Mach Kobayashi

Saw Project Hail Mary this weekend, Artemis 2 launched, and I made a short video about a moon souvenir I recently received. It’s been a nice break thinking about stuff outside of Earth youtu.be/tPwVEzhAmwc?...

We had a thing at work today…

I'm holding a grapefruit the size of my head, next to my head

My wife brought home the largest pomelo I've ever seen. It's the size of my head!

The Irish blessing “May the road rise up to meet you” hits different as a motorcycle rider…

My teenager’s conversational vibe is “this could have been an email”

Hijack with Idris Elba was so good, but I’m glad I finished it because it was stressing m— THERE’S A SECOND SEASON?!

I peel citrus in a spiral pattern with my right index fingernail while holding them in my left palm. I peel rambutan along the seam to get a clean break

“Describe yourself in an unconventional manner”

This is how I peel my fruit:

Tonight, an old friend reached out. It’d been years and we had such a great time catching up. Or so I thought. Turned out, she was a scam bot. On the plus side, I’m now heavily invested in an up and coming cryptocurrency

Starting to watch Hijack right before bedtime was probably not the best life decision ... But Idris Elba is so good!

I've heard of "tsundoku", which is essentially buying more books than you could ever read. Is there a corresponding word for coming up with more ideas for stories than you could possibly write?

One thing that Viable Paradise 25 has taught me to say: I'm a good writer!

(It did not teach me how to say that without feeling abject terror and embarrassment, but baby steps, baby steps...)

What word did you mispronounce for the longest time? Mine is "misshapen", which I thought was pronounced like "miss-happen" as in, it happened wrong...

I don't think I'm a morning person or a night person so much as I'm different people during those times.

Morning Mach: experiencing a nostalgia for the internet of 2010s with blogs, tweets, and social media dominated by friends, not feeds.

Night Mach: I wanna see my own brain in a jar.

Oh, hah, is that like supernatural? For some reason, it sounds like the opposite. I think that's kinda hilarious, actually
