Boss man did it!!
DO’s will be the agent infra for the future.
langgraph's multi agent example on a durable object

- uses ALS to "share" the DO instance with tools
- so it can make the "chart" call inside the server, but renders in the browser (yay websockets)
- also uses @mattzcarey.com new checkpointer
- the thing can run even when a browser isn't connected

Super fun to speak at a packed ai engineer london. My talk was about how we eval agentic RAG with Langsmith

Thanks @robbiehudson.bsky.social and crew for having me and for organising a great event 🙏

in 2025:
- build a cursed programming language
- publish my RAG stuff as real research
- build more models with zml
- generate 100x more tokens
learnt alot in 2024:

ML -> transformers, finetuning data mindset
AI -> search stuff, agent guardrails, evals
cloudflare dev -> awesome
modal labs -> containers in python
Data engineering -> DAGs, lineage, access control, etl at scale
Comp sci -> memory management, search algos, basics of zig

We have been building something for a while at StackOne with no idea what it should be called.

Google just told us.

We are building an extension

an extension for the whole HR tech ecosystem.

remote work hack
take lunch after a long meeting and go do some exercise.

come back with a clear head, knowing what to do. Nobody cares what time you take lunch anyway.

i've been building a thing 🦓
the api is coming together.
the model compiled by zml

I think this leans well on zml pros.
One model, many backends, zero code change.

Trying to define the AI Engineer role, I just explained it to a friend on 2d axis.

On the x axis we have designer to FE to BE to ML to Data Science

On the y axis we have cloud to hardware

AI engineer blob sits right in the middle.

wip but I think this is a nice way of thinking about it.

Streaming LLM tokens is a hype.

Give it a year and peeps will just use rapid models for quick answers and the slower models for more complex work

so much faff the last two years just for streamed tokens in chat. Horrible UX

EU ftw
It’s time for THE charger.

Today, the USB-C becomes officially the common standard for charging new mobile electronic devices in the EU.

It means better-charging technology, reduced e-waste, and less fuss to find the chargers you need!

made a lil website for my granny.

She needed some photo storage for her (soon to be an online) bookshop. Build her a nice little admin panel

and it has dark mode :)
