The first five chapters of our 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 𝐃𝐞𝐬𝐢𝐠𝐧 𝐏𝐚𝐭𝐭𝐞𝐫𝐧𝐬 𝐛𝐨𝐨𝐤 are up on the O'Reilly website. Labor of love from me and Hannes Hapke, but also a great learning opportunity as we got to explore things we didn't personally use.

Hold on your outrage. They just show the map per the official edicts. Indian and Chinese users do not even see the same border.

They open sourced their entire training regimen. Deepseek trained their model from scratch using the same technique that AlphaGo used ("self-play") and that requires both less compute and less labeled data. They are legit.

Hair ice that we saw on our weekend hike near Seattle.

It is a rare type of ice formation caused by a specific fungus releasinv moisture from a specific kind of rotting wood when the weather conditions are just right: www.discoverwildlife.com/plant-facts/...

First hike of the year was in our backyard. This is Far Country Falls, a seasonal stream on cougar mountain. #seattle #wta

LLM-powered workspaces are the next new office productivity tool. This excellent article clarifies how to organize your sources, transcripts, thoughts, etc. and extract insights into templated formats (like PRDs) using one such tool. The underlying ideas are applicable to any white-collar work.

Things India could do to make itself friendlier to tourists:
(1) Enable easy access to UPI to foreigners or via credit cards
(2) Allow e-SIM purchases based on passport, i.e. without aadhar/PAN card
(3) Make websites accept foreign credit cards and send OTPs to foreign ph numbers to enable planning
Why you’re not on holiday in India right now
A fabulous destination for foreign tourists does little to lure them

Ideally, you can evaluate agentic applications even as you are developing them, instead of evaluation being an afterthought. For this to work, though, you need to be able to mock both internal and external dependencies of the agent you are developing. Dependency injection in PydanticAI unlocks this.

Is this AI-generated? People have long wanted to see GNB sing and Palani play, but they were before the movie era. And then this clip shows up. What do you think?

"My agentic system can answer questions and call backend APIs" is the GenAI equivalent of "My program complies". You don't know whether the program works until/unless you evaluate against reference answers and actions.

The changing face of America -- today, in Bellevue, WA, a Canadian Asian supermarket chain opened at the location of a Walmart that closed last year after struggling for years. This is now the largest grocery store in the state & is supposed to have excellent bakery, sushi, and dimsum made daily.

College costs have been dropping, but "men and women were about equally likely to say that not being able to afford a four-year degree was a major reason why they hadn’t completed college." It's essential that we turn this perception around.

Fewer young men are in college, especially at 4-year schools
College enrollment among young Americans has been declining over the past decade, and it's mostly due to fewer young men pursuing degrees.

Thanksgiving is a day when my wife and I celebrate American food, which we define as anything my we didn't grow up eating, and learned to cook after we moved here. (Item names in alt text). Happy Thanksgiving!

Spotify has no clue about Indian languages or music genres. I mostly listen to carnatic music, mostly in Tamil but some of whose 19th century classics were composed in Telugu. Spotify will go on a jog where it seamlessly transitions from them to Telugu film songs (A) Wrong language. (B) Wrong genre.

Familiar trails in Cougar Mountain look very different in the aftermath of the "bomb cyclone". Debris, fallen tree trunks that you have to limber below or vault over, newly uprooted trees, dead trees sliced in the middle, others that have slid down the hill slide, a lone madrona stripped of bark ...

What a difference a week makes! Salmon pair spawning last week in Issaquah Creek. Those streams are probably water logged now, after the bomb cyclone -- the salmon wouldn't have been able to make it there now.

i'm sorry to say this but if you send me a tiktok of a person telling a story into the camera for 3 minutes i'm not fucking watching it. just in general ever. people need to start typing things up again because i can read so much faster than you can talk and i'm not wasting my precious time on this

Thru-hikes are logistically hard, but can offer outsize rewards. Hiking along Rattlesnake Ridge, from Snoqualmie to North Bend, you get great vistas, glimpses of Rainier, looking down on Rattlesnake Ledge. It's a great 11mi walk with unusual viewpoints. See if you can swing the logistics. #pnw #hike

Always good to reflect on the unfortunate truth that there all sorts of discoveries we'll never witness due to the finicky and sometimes regressive nature of peer review and hollow demands to do research attractive enough to get grant funding.

The trail to Heather Lake is steeper, shorter.and wilder than its better known neighbor, Lake 22. And the lake is just as spectacular. Was lucky to catch fall colors and a calm reflection.
