I don’t have time to do a big iOS 26 feature upgrade. A compatibility update still possible.

In 6 weeks of Claude Code, I got through a year or two of @puzzmo.com tech debt

Switched React Native -> React, Redwood -> In-House, Jest -> Vitest, animations to Motion, Design System -> Base UI, Node upgrades, Vite upgrades, made Monorepos

All on the side, solo

6 Weeks of Claude Code
It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of qua...

I got a Lingo Glucose Biosensor and just applied it on my arm.

Surprised that I didn’t feel a thing since the needle is longer than tiny?

Will report back my next 14-day journey!

I can now be installed with pip install y2.

Happy to be tool called by agents.

Peace.

Today, I used the phrase "excuse me, but I'm talking," when a man started to talk over me during a casual conversation

Then having another woman a few mins later being like "I appreciate you not taking any shit" ❤️

Posted with permission from him, he apologized, and no ill will

While I missed the remaining talks today, on my flight back from #PyConUS I was quite productive and made a new thing!

pyref.dev is a fast, convenient way to access Python reference docs.

It's also available as a CLI tool (pip install pyrefdev).

Hiking Maui’s Hidden Bamboo Forest
# Summary We accidentally discovered this hidden hike in 2015 while we were heading back from Hana. We stopped at a random spot to take some pictures. On the opposite side of the road, we noticed some hikers just emerging from what seemed like nowhere: ![The Hidden Entrance to the Bamboo Forest](https://lh3.googleusercontent.com/TbiIv3PMOSAs49BudOGMq9a1kx1W8GOeo04R0n112I_W9WcDw1Huc0QTOHNc0GkQKpU4s4RU-M_PyYEGGQbvV9TTDuSZWe_f=s1200) Intrigued, we investigated and discovered a narrow trail winding into the bamboo forest. Unfortunately, it was already late that day after our trip to Hana, so we didn't venture very far. When we returned in 2017, we made sure to explore this trail again. It turned out to be the best hike we experienced in Maui. Fast forward to a few weeks ago when we brought our 6yo on the Road to Hana, we simply had to stop there. The experience was even more magical with the swollen river after the recent rainfall. # Photos ![Photos from Hiking Maui’s Hidden Bamboo Forest](https://lh3.googleusercontent.com/dR92HHv-jayXELj7-2R_xQfvrp5WKjA-7dalju-yEJdpmYvuLHwAWCrv23bKSIoMx3p-LHSZzltwIDj5jbtQJLfYz6j2T1UY0A=s1200) ![Photos from Hiking Maui’s Hidden Bamboo Forest](https://lh3.googleusercontent.com/huOybEAEGS6YANHtu8jcUeXZdvJbKluBpD6TCLy83kq0FxtTiITPxVuXnxQ0_nQxPS_5hJYr4xLd-et-VYMiHd3b8IF_HEQx=s1200) ![Photos from Hiking Maui’s Hidden Bamboo Forest](https://lh3.googleusercontent.com/P9fHAfK5cKci3N8VuQnv8RD8psHb-TYfdSS5ceyJx-Q7NCCkLyICAiyjbqHITE4zndF5s9ncxVvTctHyCvfUm8SeY5B_wTjrrg=s1200) Photos from Hiking Maui’s Hidden Bamboo Forest # Numbers Time: 2025-04-19, 2.8 hours.
