While I rarely accept agent generated code without charges, it is crazy how much it has changed workflow. Cursor is still my favorite over Claude Code, probably because it keeps me more in control. My favorite new feature this year has definitely been the in app browser.

I don’t understand why there aren’t any cloud development #agents that can run inside a #devcontainer. How do people use these if they have random versions of their languages and tools installed and no infrastructure available. That’s not how we develop locally why would an agent not need this?

I love your writing. But this is a bit confusing. Since AI doesn’t really have a memory. Just telling it something in a chat won’t alter its behavior beyond that chat (and depending on the provider maybe the next few chats). Some providers allow for global context. But AI cannot remember or learn.

Writing Code Was Never The Bottleneck LLMs make it easier to write code, but understanding, reviewing, and maintaining it still takes time, trust, and good judgment.

Completely agreed. I love coding with Cursor and Co. but I can’t get faster than my speed of understanding what the code does and making sure it fits within our architecture.

#Python 's #TypedDict is way under valued. It has type features like dynamic type inference, not required (aka undefined/unset), tagged (aka discriminated) unions, and kwarg unpacking (aka destructuring) support. But instead #pydantic and data classes that lack these features are used more today.

Yeah there’s a few blogs using it as the commenting system these days. You could build much more with the AT Protocol, but my current implementation is pretty simple github.com/MrLoh/mrloh....

It’s Never too Late to Learn Something New A personal story about how blogging led me into software engineering, and why it’s never too late to learn new skills - from web development to machine learning.

Reinvent the Wheel | Matthias Endler One of the most harmful pieces of advice is to …

Could not agree more with this. Many of the most fun and most insightful things I’ve done in my career have been reinventing the wheel, libraries for anything but the most low level things are overrated.

I really don’t like ChatGPT’s new memory dossier Last month ChatGPT got a major upgrade. As far as I can tell the closest to an official announcement was this tweet from @OpenAI: Starting today [April 10th 2025], memory …

Chat will not replace traditional UI because it ultimately has a lower bandwidth than a purpose built UI, but it can be a usefull addition to the UI toolbox alongside traditional application UI.

AI as Normal Technology

A bit lengthy but a strong argument for why we need to treat AI like normal technology and get lost in the AGI/super-intelligence hype-train.

I think the biggest gap is the lack of a server side middleware for actions. I’m currently rolling my own, but it requires a lot of documentation and is a steeper learning curve for other devs on the team than if react had something built in that would allow injecting context via middleware.

Yeah that’s one of the downsides of not having HTTP verbs with standardized idempotency. I’m currently handling this by sending results over the wire and having shared functions which handle appropriate error UX and could do things like retried.

I wouldn’t write an API without a framework that helps with handling session/db/etc. context management and I don’t usually call fetch without a client that handles retry logic and standard errors.

I think the directives are a great evolution from tRPC and use client feels very intuitive. The only thing I struggle with is the lack of middleware on both the client and server side of the action.

PydanticAI Agent Framework / shim to use Pydantic with LLMs

I moved on to ai.pydantic.dev now which looks like it’s built by engineers who actually know modern Python well.

Also the whole event thing is build in a way that you have to declare types that you don’t adhere to if you use parallel dispatching of events and collecting them. Tons of different examples in the docs and examples raise type errors. It’s embarrassing.

`llm.structured_predict` wraps an OpenAI method that has proper generics and drops them to return `BaseModel` that is way way worse than returning Any since it means now you can’t use this code without doing a cast or type ignore statement.

@llamaindex.bsky.social Why is the typing of llamaindex workflows so f*ed up. Declaring return types like BaseModel is a really bad idea, because it means you can’t write type safe code against it. Better to not declare types if you don’t know how to.

Bluesky seems really awesome (like what Twitter used to be before it became all adds and videos and political content). Gonna give this a shot and planning to setup commenting via Bluesky on my upcoming blog using the AT Protocol.
