Hue9 just passed 6K users in 7 months. Is the graph slowly going down? Yep. Do I care? Not really. 6,000 people played a little color puzzle I built after work. I’ll take that fucking win.

The first trials for Oraia are landing. Now fingers crossed they turn into full subscribers step by step.

My second app is now live on the App Store 🙏 It’s called Oraia, and it helps you pray every day at your own pace, even if you don’t know where to start. Weeks of solo work, and it’s finally out. 👇

Is there anyone with an iPhone Duo on my timeline who could do me a favor?

Has anyone actually managed to run Claude Code on a Fire TV Max to clean up all the bloatware and trim down the UI, or is that only a thing on high-end setups? Has anyone pulled this off?

Is there an open-source equivalent to the newly announced Keychron Orca Echo? Looking for split keyboard PCBs and 3D printable cases that integrate a trackball or a trackpad. Any pointers for a DIY build?

It’s been a month of losing more followers than winning.

Recently, I’ve been reading several articles and discussions about how AI is impacting dev work, and there’s an angle that rarely gets enough attention: the developer's identity crisis. The real issue isn't just whether AI will replace jobs or make us 10x faster. It's what it transforms us into along the way. For years, the true satisfaction of this craft came from the process itself: solving complex architectural problems, tweaking UI details, and knowing you built something with your own hands. There was a genuine element of craftsmanship in writing software. Today, momentum pushes us from creators to supervisors. You end up being a babysitter for an AI agent that spits out hundreds of lines in seconds. Sure, shipping faster gives a quick dopamine hit, but you lose control of the how and that real sense of authorship. For juniors, it bypasses essential hands-on learning. For veterans, it feels like it dilutes the value of thousands of hours spent mastering the craft through trial and error. Velocity is at an all-time high, but pride in the work itself feels at an all-time low. Are we trading away software craftsmanship just for raw speed? How do we balance shipping fast without losing the personal fulfillment of actually building things?

Hue9 had a huge user spike on Oct 30 and I genuinely don't know where it came from. Still searching for any mention I might have missed. If you know something, tell me!

Safari locks up on X unless I clear cookies, but as soon as I log back in, it freezes again. 48GB RAM and an M4 Pro, yet here we are. What browser are you using in 2026? Need Passwords compatibility. Bye Safari Reading List, hello stability.
