I wrote about how I built my app Ductts! cassidoo.co/post/ductts-...

One very annoying habit of Claude Code 4.5 model is that it tries to replace `foo === false` with `!foo` and claim that it's (a) not the same; and (b) will fix any issue I complain about.

It’s incredible how many things AI agents do right, and it’s incredible how often they can’t solve a certain issue at all. Here’s just a little gem from Copilot.

Did you know that AVIF (the AV1 Image File Format) was supported in all the major browsers (Firefox, Safari, Chrome/Edge)? This has been the case for almost 2 years at this point.

Node.js 25 is here! We have upgraded V8 to 14.1, bringing major JSON.stringify performance improvements and JIT pipeline optimizations. This release introduces the permission model --allow-net, Web Storage is enabled by default, and more! nodejs.org/en/blog/rele...

Having a blast re-designing all the React Aria examples this week. Flat design is so over – bring back depth! 😃

Made a new PostCSS plugin for generating more realistic smooth shadows like on smoothshadows.com Now designers usually rely on generators, but the resulting code is often hard to maintain. github.com/postcss/post...

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 🤖

Infinite monkey theorem 2.0: A monkey prompting independently and at random an AI agent for an infinite amount of time will almost surely produce any given software.

Suddenly, I got Copilot autocompletion in my Outlook on macOS, and there seem to be no way to turn it off. It makes it totally impossible for me to write even the most basic email — the completions appear too fast and distracts me with mostly unrelated suggestions.

Here, @microsoft.com is basically saying that you cannot have a verified domain on @vscode.dev Marketplace as an indie developer. I _do_ have links to my extensions right on the homepage, but apparently it's not enough anymore.

Some very good points on accessibility of glassmorphism, though the whole article gives me very strong GPT vibes, and lacks any visual examples. I can confirm most points — the default iOS 26 with reduced transparency and motion disabled is essentially unusable for me. axesslab.com/glassmorphis...

"Visually appealing interfaces may unintentionally impact user experience and exclude users if motion, transparency, and blur effects are used without giving accessibility top priority." #a11y axesslab.com/glassmorphis...

Defaults matter. Remember that people tend to internalize bad UI as their own personal failing, and that people also may not identify as disabled. Combined this means they'll feel bad using inaccessible experiences and not think to check how to fix the problem. www.theverge.com/news/802963/...

The new Vite+ looks very interesting, and may be a perfect solution for my personal projects: * Linter, formatter, test runner, library bundler, etc. in one tool. * Linter is compatible with ESLint. * Faster and easier configuration and updates. voidzero.dev/posts/announ...

🗣️ My talk "Decluttering Sentry - One Knip at a Time" from @react-prague.bsky.social is now available on YouTube ✂️ This is a real-life story (with ups and downs) about how we used knip by @webpro.nl at @sentry.io to delete 20k lines of unused code and now run it in CI so it never happens again 🎉

DHH is the biggest reason why I don't use Rails anymore. This post (and especially the linked talk) get to the heart of hte problem. davidcel.is/articles/rai...

Polypane 26 is here! Emulate safe-inset-area variables and the small viewport height inside Polypane for the most accurate device emulation available. Of course there's more, like improvements to inspection, measurement overlays, Chromium 140 and much more. polypane.app/blog/polypan...

I’m thinking of joining some webrings. Would you recommend any?

Thank you for listening to me #LoopConf 💛 Slides are available at noti.st/anarodrigues... Send me your personal website!

This book (Code Health Guardian by Artie Shevchenko) came recommended by an experienced software engineer as a great read. Starting it now. On first glance, it looks like a promising one, going back to software engineering basics that start to become more important with GenAI

📝 On a recent episode of Decoder, @reckless.bsky.social asked the question “Why would anybody start a website?” It struck me a bit and I started making a thread... but it got too long, so I blogged about it... on my website. daverupert.com/2025/09/why-...

🚀 Just shipped Tidy Space extension for VS Code! Tired of your laptop screen looking like a cluttered desktop? This extension keeps only ONE sidebar open at a time. No more wrestling with overlapping panels eating your precious screen real estate: marketplace.visualstudio.com/items?itemNa...

After years away from blogging, I finally wrote something new. It’s my reflection on how AI and LLMs are reshaping developer culture. I touch on the hype, the reality, and how these tools have found a place in my daily workflow. plekhanov.me/blog/rhythm-...

If you like keeping quick notes right next to the code you’re working on — like I do — this VS Code extension will come in handy: marketplace.visualstudio.com/items?itemNa...

Thoughts on using AI for software development at @dev.to dev.to/sapegin/thou...

This one works well. I used to use another extension, but it stopped working for me.

A new post on my blog with my somewhat random and disorganized thoughts on using AI for software development: sapegin.me/blog/coding-...

I’m experimenting with a simplified spec-driven approach inspired, where I use two custom agent modes (tested with Cursor and Kilo Code for now): the first to design the future and show me an implementation outline for approval, and the second to implement it in code. github.com/sapegin/two-...

This is what happens when you let AI make decisions. Wonderful onboarding on Claude Code, when I just tried to register.

Easy to miss a11y detail: if you remove DOM elements while they're focused – move the focus to another relevant element in the same group ✨

Polypane 25.1 is out! - DRM support: use Netflix, Spotify etc in Polypane - Re-open closed tabs feature - Bug fixes and improvements to the elements panel, outlines, form autofilling and more. polypane.app/blog/polypan...

All my @vscode.dev extensions are now available at Open VSX Registry, meaning you can install them in Cursor. open-vsx.org/namespace/sa...

How do I tell Cursor not to write any code until I agree with their implementation plan? I have this piece in .cursor/rule, but it doesn't make any difference.

I have a similar concern too: now LLMs are trained on content written by humans. In a few years from now, most of the content on the internet will be written by AI. How LLMs are going to keep up with this?

Time doesn't really matter when it comes to art. Most people happily wait a few years for an artists to bring out their next record, book or play. Few need it generated in seconds.

🖼️ My #CSSDay slides and all the links are up on talks.hiddedevries.nl/3do3c4/displ... humbled by all the friendly responses to this, it felt like there was real appetite for people to make their sites greener. I love to see it!

Polypane 25 is here, and it's a nice one 😎 - Browser extensions with manifest v3 support - Forms outline with errors and suggestions - Chromium 138 - Lots of quality-of-life features polypane.app/blog/polypan...

This felt important enough to give away instead of keeping it just inside Polypane.
