Just over 4 hours of exposures for Bode's Galaxy last night with one or two more clear nights in the forecast this week.

Hoping for better results this time with a small set of shorter exposures to process stars and Galaxy separately.

What I Learned from my First Vibe Coded Project What I Learned from my First Vibe Coded Project I haven’t manually written large portions of code in quite a while thanks to Claude and the improvements made by Opus, though I typically am still very ...

I think all seasoned software engineers should try their hand at vibe coding *something*. It's uncomfortable, but you will learn things about AI-native development that you might not have by hand-holding coding agents.

Tech Writing in the LLM Era Tech Writing in the LLM Era

A short stint in Maui then some landscaping / gardening work! Maybe a little cliché, but excited for more hands-in-the-dirt than hands on a keyboard 😁

Week 1 of my sabbatical - refreshing myself by spending a little brain power on HUMAN intelligence. A classic.

Starting my sabbatical on Monday and this has got to be arguably the weirdest time to disappear from the industry for 8 weeks.

The updated skill-creator skill is very cool. The built-in evals are a game changer.

Are you building or buying Evals?

I take this back.

A well crafted MCP can mask a poorly defined API pretty effectively.

Don't ask me how I know...

The growth of AI Assistants and usage is forcing a tighter focus on APIs as a product.

Evolution over time and a lack of "incentive" to consider even core APIs as product really becomes obvious (and problematic) when an AI Assistants needs to understand and use them effectively.

Finally, some clear nights.

(I promise "night sight" makes the light pollution look way worse than it is)

Curious what people have run into when adapting existing core services to support AI use cases (agents, MCP-style tool interfaces, LLM-driven interactions, etc.).

What surprised you? What broke in weird ways? What do you wish you’d designed earlier?

Totally! And yes, definitely give Claude a shot if you can. Agent Skills have been super impactful for me so far. I'm tinkering with a Skill now that updates itself with summary learned business logic as it goes to cut back on the need to re-learn on future invocations. Effectiveness of that TBD.

How AI Is (And Is Not) Working For Me As A Staff Engineer How AI is working (and not working) for me as a Staff Engineer AI tools have really only become a serious part of my daily workflow within the past year or two. This post is meant to be an informal re...

2025 has been the first year where I REALLY embedded AI tooling into my workflows. Here's a quick brain dump around how AI tooling is (and is NOT) working for me right now.

Let me know about your experiences as well!

This was a tricky one! Diagnosing (seemingly) random, low volume 10x performance regressions on Rover Search.

I re-watched Krull last week. The 80s gave us some truly iconic movies. Think of all the weird movies we could have today if the DVD market and movie theaters didn't collapse under the weight of streaming.

Claude Agent Skills are super cool. Having a lot of success organizing more intricate workflows this way!

I finally pulled the trigger on a Niche Zero grinder as part of my "endgame" espresso set up and holy cow this thing is awesome.

Are we still doing starter packs?

Put this one together because I love seeing things that lovely folks write on the internet, and I'm sure there are more people to meet and add to this list.

I know it's at least not uncommon for coding bootcamps to strongly encourage (or even require) students to reach out to practicing devs as a networking exercise. Maybe that's propagated beyond bootcamps now?

I field a few of these regularly, though not at the volume above.

Basically everyone is running some sort of AI adoption / advocacy programs within their tech organizations.

Is anyone also running some sort of "AI Responsibility" or "ethics" programs? How's that going? What's working for you?

I'm always looking for ways in which my "Personal AI Principles" are pressure-tested by reality.

Recently, for example, I've found that I'm willing to bend on my, "Plan and edit, but do not write using AI" principle specifically for technical documentation.

Finally committing to scheduling my sabbatical. Going to spend 8 glorious weeks gardening and pointing my camera at the stars next spring.
