Has anyone tried actually running experiments on how they develop with LLM-assisted workflows? I see many subjective takes (pro and negative) but think it'd be neat to record a significant stretch of:
- no AI usage
- "moderate" usage (e.g. autocomplete, lite chat)
- heavy usage (IDE + agentic)

Got asked at Thanksgiving by a family member how to get hired in tech. Like many juniors I've interviewed, their resume/github is all toy projects, which is good for learning but not hiring.
I tried to think about what I would do if I had no experience, but knew what I know now.

Every so often I get into a debate on tailwind (mostly yakshaving, IMO).
It goes back and forth, usually with people speaking past each other. I finally sat down and put my experience into words on why I like tailwind (and where I don't).

Frontend is failing. 75% of devices with browsers are smartphones, but not even half of sites pass Core Web Vitals on them. Why not? Too much JavaScript, added to indulge SPA fantasies the data is falsifying in real time:

Gleam seems like a much softer entrypoint into the BEAM than Elixir or Erlang for frontend engineers more used to Typescript/C-derived languages.
Has anyone made a component/JSX-like templating framework for it? Lustre is elm-y, which I like but is likely foreign to the average React dev.

A couple of weeks ago at @perfnow.nl I gave a talk called "Fine-grained everything". It's about @svelte.dev (obviously), and the new frontiers of framework-land, but it's also about some stubborn misconceptions in web performance circles

How can we have less polarizing discussions on new technologies/ideas in software? So often it seems we speak past each other, often oversimplifying problems in order to rep "our camp".

Someone explain Elixir / Phoenix LiveView to me. What do you like about it?
The model reminds me of sync engines, except Phoenix LV is attacking the problem from the other direction: "what if server side rendering was reactive?" vs "what if client reactivity, but with server state as src of truth?"

Anybody managed to get a SvelteKit app in a Deno monorepo running on Deno Deploy?
It can't seem to figure out that the root isn't where the dist is, and there doesn't seem to be any obvious way to override the build directory.
Tried many things/am abt ready to throw my hands up and go back to CF.

I want to love @deno.land (as I think their vision is the right direction), but it feels like adoption is slow despite their advances since 2.0.
Are there any medium - large companies / projects using Deno that can speak to it?

The duality of wanting to try every new sync engine on the block while also absolutely not needing a local data model for anything I'm currently building.

One of the bigger challenges I have had promoting @solidjs.com is assuming developers have a general idea of how their tools work. I'd show off fine-grained rendering, and be met with "Isn't that how React works?" I'd find myself educating them more about their existing tools.
