Software Engineer from Rotterdam. Mostly frontend with Svelte and SvelteKit.
I refactored the Footer component of my SvelteKit website to use a `prerender` remote function to read a commit hash from an env variable.
But @kevinmackenzie.bsky.social pointed out that it broke the navigation. This was the fix: github.com/maiertech/we...
I have no idea why it broke.

New trend in my inbox: SPAM emails wrapped in Google Calendar entries.
Interesting approach to wrap crap in an email that will breeze through SPAM filtering. And a potential problem for any service that uses customizable transactional emails.

It ain’t easy to move a side project off Big Tech
Migrating a side project from Vercel to Railway exposed the challenges of moving off Big Tech, and the price tag in terms of time and effort was higher than expected.

One of the few real world examples of a bookmarked PWA being promoted at a larger scale.
This is what you see when you try to install the official emergency app in my area.
Kudos to to whoever decided to opt for web standards 👏

Self reviews were a good idea before AI but are now a necessity. Don't put that burden on your co-workers. If you use AI, review it 🤖
So I'm reviewing a PR from a colleague that was written for like 95% by AI, and while it might have made his job easier, it's making mine a lot harder because it's riddled with mistakes and issues that I have to now fix, and I feel like I have to thoroughly check every single line of code twice

If getting hired is broken even for @nerdy.dev, it needs to be fixed!
Adam's interview with @kevinpowell.co really resonated with me. I wrote down some insights from the interview.

Why multi-step AI workflows are overhyped
Why long, multi-step AI agent workflows often fail: compounding errors, rising token costs, and fragile tool integrations.

While I wait for Apple to fix all the little things broken across devices, I'm still trying to wrap my head around that they had nothing else to do for a year other than focus on transparency gimmicks and rounded corners.

Fun little interaction challenge: one select changes the options of another, which needs to load data depending on the first.
This is how you do it with the new Svelte APIs. Comfortably fits into one screenshot.

I give Vercel credit for transforming frontend dev with immutable deploys. Abstracting away servers was liberating.
But as times change, the downsides of this model deserve more attention.
I have switched to Railway as stepping stone toward a European hosting solution.

Has anyone building with #SvelteKit and `adapter-node` seen this type of error?
Screenshot is a Railway build. Local build works fine. Happens occasionally.
This is a Vercel to Railway migration. Never had this issue on Vercel.

Using `<enhanced:img />` in Markdown in a mdsvex file in combination with code fences that look like Svelte confuses the Vite plugin.
Wrapping `<enhanced:img />` in a Svelte component and import that component into an mdsvex fixes this.
But it's not pretty.
