Thinking a lot about what @GergelyOrosz calls "product-minded engineering" & the recent work of folks like @kentcdodds. Here are my thoughts from the product leadership side of the table & what I've learned from industry greats like @ttorres & @shreyas: x.com/samjulien/stat…

If you want to learn about graph engineering, Anthony Alcaraz have spent the last 6 months writing the definitive guide. It takes you through vertical KG and horizontal workflow graph construction, self-evolution, & optimization backed by research and case studies.

@Saboo_Shubham_ More here: oreilly.com/library/view/a…

@Saboo_Shubham_ In my book we distinguish between the vertical knowledge graph (what the agent knows) and the horizontal workflow graph (how the agent acts). It looks like this:

wtf is a graph. Loops made Agent behavior programmable. Graphs make agent orgs programmable. Dynamic Agent Org is where the graph rewrites itself while the work is happening.

In our book we distinguish between the vertical knowledge graph (what the agent knows) and the horizontal workflow graph (how the agent acts). It looks like this:

@steipete Already there

Are we still talking loops or did we shift to graphs yet?

Graphs help with the whole agent stack: Knowledge construction Tool orchestration Evals Memory Optimization Have I got the book for you

@svpino Have I got the book for you: oreilly.com/library/view/a…

Loop Engineering is dead. Long live Graph Engineering!

@CopilotKit npm install @copilotkit/aimock github.com/CopilotKit/aim…

One of the coolest open source projects we have @CopilotKit is aimock. It provides deterministic mock infrastructure for AI apps. For free! Also works with MCP, A2A, AG-UI, vector databases, and services. Check it out and let us know what you think!

@ChiefScientist Haha fun fact about me is that I actually am from Swedish lineage not French. That always throws people off with my name

That's because julienne is popular, but congrats! Julienne (sometimes spelled "julien") is a knife cut, not a specific food. It refers to slicing vegetables or other ingredients into thin, uniform matchstick-shaped strips, typically about 1/8 inch thick and 1 to 2 inches long. The term comes from French cooking. You'll often see vegetables like carrots, celery, peppers, cucumbers, and zucchini cut this way for stir-fries, salads, garnishes, and slaws. The classic example is julienned carrots—those thin little strips you see in salad bars or garnishing a plate. There's also a related dish called "julienne soup," a clear broth garnished with vegetables cut in this style, which is actually where the name is thought to have originated. If you ever see "julienne" on a menu or in a recipe, it's telling you the shape the ingredient is cut into rather than naming an ingredient itself.

I’ve been stuck at 9800ish followers for like 4 years since the algo changed. Lo and behold they fixed it and today I crossed 10k! 🎉 Grateful for each and every one of you, especially now that I actually show up on your TL again 🤣

@tessak22 Hopefully! I bet yours will start to come back around now too with the algorithm change

@samjulien Me too! Then I finally reached 10k, then like 500 people left X around the same time. Haven't recovered yet. Congrats on your win! Hopefully you get to keep yours!

@MayaShavin Maybe we are crossing the divide now 🤞

@samjulien Wow awesome!!! Mine was stuck at 5.5k and then went down 😢, and never recovered since

@manishtyagi__ Thank you!

@samjulien congrats, way to goo!

@michlbrmly Sick! I love how having kids gives us an excuse to return to old hobbies and sports 😀

@samjulien my kids got old enough that I finally managed to get them into skating, which means I could start skating again. Honestly I am living the dream these days.

Given that the last time the algorithm was good was in the era of sourdough and Tiger King, what hobbies have you gotten into the last few years? I have a little kid now so all of my hobbies revolve around baseball, cars, trucks, and superheroes now (definitely not complaining)

@JeremyCMorgan Haha very cool and love the rubric

@samjulien FPV drones, and competitive sim racing. Both of them meet my standards of a great hobby. 1. Steep learning curve 2. Take forever to get good at 3. Spending more money won't make you better at it it's been frustrating and fun at the same time 😂

@gwenshap Wonderful! What a great combo

@samjulien Off-road adventures and watercolors :)

@rachelnabors Oh nice! I love chess even though I'm probably fairly poor at it and I've been a drummer for a long time. Mandarin is such a cool language. I would love to learn that someday.

@samjulien Learning chess, drums, and Mandarin!
