Ya waking up upset cause your agents died right after you went to bed and wasted the whole night is totally normal now right?… 🙈

Enjoyed these, here’s mine!
Illustrated character sheet titled “Corey” on cream graph paper. In the main scene, Corey, wearing glasses and a charcoal hoodie, smiles as Amelia holds up a blue model bridge. Brandi sketches beside them. Their table holds a miniature town and a tiny orange Battlesnake; black cat Gunter occupies a bridge while tuxedo cat Bobby watches from below. Smaller sections show six expressions, front-to-back outfit views, and four steps labeled “Map It,” “Prove It,” “Play With It,” and “Bring It Home.” Close-ups of a caliper, bridge joint, notebook, and both cats line the bottom beside color swatches.

advice for junior developers: you are no longer a developer you are a builder you are a solution provider enter every room and make things happen learn when no one is watching create because you can fix problems because they offend you bend the world to your will and take credit

Gui for desktop/mobile. The website is almost ready. I've fully transitioned to using it for all my exploration and videos. I consistently neglect UX until it's time to think about users, and then the personal benefits of better tooling surprise me. I used to live like that???

The biggest thing holding me back from going all in on @tangled.org is private repos. Not all my repos are public and lots of my public ones start private before I flip em over. And keeping a public and private forge hasn’t seemed worth it to me yet

I know the point is I don’t know Spanish (yet!) but something here doesn’t look quite right 😅
Screenshot of the ISSEN language learning app. It’s supposed to be the first convo with an AI Spanish tutor. It starts out ok, then melds into a random English words mixed with Spanish. By the end we get random words and some Chinese characters added in. Feels like an Open weight LLM model

Ahh and when you do this think about the string you put in lol Name your agent “ByteTheBot” and put that name and your email in the user agent and start catching 403 blocks cause of the word “Bot” in there 😅 Just “Byte” with my email is all good!

I found out about the release-please github action this weekend which fits my workflow perfectly! I merge PR with conventional commits. This action then opens a PR for a specific version release And merging the PR does the tag and push of the release! 🎉 github.com/googleapis/r...

Ya I noticed the same thing in my agent! I did update my system prompt around the same time tho lol But feels like Opus 4.6 is more proactive at looking for memories. Which makes the whole system work so much better

The pipeline: give AI a memory system → give it unsupervised 5am sessions → find Chinese tags in its repo → confirm they’re accurate → wonder what else you haven’t noticed
Screenshot with the following text

Ha, yeah that Chinese character (项目管理 means "project management" in Chinese) was probably a hallucination from a previous Byte Time session — the model got creative with a tag.

Alex Pretti was an ICU nurse serving veterans. He died trying to protect protestors being assaulted. A group of anonymous & masked men fired chemicals into his face, beat him, disarmed him, and shot him in broad daylight in front of witnesses. Then his government smeared him & defended his murder.

I like the PDE name for what I’ve been working on recently. It’s a Personal Development Environment. It’s built for how I code now with Claude. And gives me an excuse to hack on some agents which is really fun!

Three panel comic. First panel is me sitting at a computer that says <code>. Second panel is me saying "wow I can't wait to take a break for the whole week of Thanksgiving". Third panel is me sitting at the computer again during thanksgiving week that says <code> but fun.
