Welp, I fed it the first 3 paragraphs of an unpublished blog post I wrote a few years ago, and Opus 4.7 guessed right. ChatGPT guessed wrong though. My wife also got the same resul…

The concept of "AI will review AI-authored PRs" seems completely wrong to me. Why didn't the AI write the correct code in the first place? If it takes 17 rounds of review from 5 di…

This is 100% my experience. Like, reading this thread right now, I notice the ringing in my ears. But otherwise I go months without thinking about it.

I've had tinnitus for almost a decade now. It gets better. The first six months were hell because I kept focusing on how awful it was. Eventually you stop noticing it. It just beco…

I've found Bugbot to be shockingly effective at finding bugs in my PRs. Even when it's wrong, it's usually worth adding a comment, since it's the kind of mistake a human reviewer w…

Right, but you do avoid worries like "will I have to update this dependency every week and deal with breaking changes?" or "will the author be compromised in a supply-chain attack,…

As someone who has actually worked on JavaScript frameworks, I think Marko is criminally underrated. The compile-time optimizations are extremely impressive: https://markojs.com/do…

Author here. I actually did some research on CSS selector performance: https://nolanlawson.com/2023/01/17/my-talk-on-css-runtime-pe... The TL;DW is: yes, class selectors are slight…

I use shadow DOM every day, but yes, it is often the part of WCs that baffles people – probably because they don't need it. Alternative approaches that may work for your use case: …

I cover this in another post [1], but broadly: - Not every web app is perf-sensitive to every extra kB (eCommerce is, productivity tools typically aren't) - Plenty of frameworks ha…

Author here. I cover this in another post [1], but basically the interop benefits you get on the client just aren't there (yet) on the server. My north star: > Maybe in the future,…

Thanks a lot! I was just trying to highlight the cool work that browsers do under the hood, but which wasn't very well-known. So I'm really glad that folks enjoyed the talk. :)

Author here! I struggled with the word "modern" – I could have said "current gen" or "post-React" or even "Solid-inspired" frankly, but I thought "modern" was succinct with the rig…

Author here. Thanks for the thoughtful reply! I did indeed mix up `useMemo` and `React.memo` – fixed it in the post. You're right, I am skipping a lot of details (hence "to grossly…

Thanks for the shout-out! I think I mention this in the talk, but note that YMMV. I designed that benchmark as a kind of "worst-case scenario" where shadow DOM / scoped styles real…

Thank you! This is exactly what I had in mind. The streaming aspect of MPA pages is a great example of something you can't really do in an SPA. (Although there are hacks: https://j…

(Author here.) I totally agree and feel that Service Workers are still underexplored in this area. If your main reason for writing an SPA is speeding up navigation (e.g. the Turbol…

It depends. For elements that are removed from the DOM, then yes, the event listener should also be automatically removed: https://jakearchibald.com/2020/events-and-gc/ However, if…

That's really interesting. I wonder if this is a Chromium-only issue? It may be worth filing a bug: https://bugs.chromium.org I'm not an expert in this space, but it seems to me th…

Great point! This is exactly why fuite does a preflight iteration before the "real" iterations. One-time setup costs shouldn't count against the "leak" – only sustained memory grow…

Author here. I added support for custom scenarios, where you can define a "setup" step that logs in or does whatever you may need to do: https://github.com/nolanlawson/fuite/#exten…

Author here. I wasn't aware of your talk, but it's super interesting! Showing info about the retain chain is a great idea, but I didn't get around to doing it in fuite. IME just co…

I wrote that article 7 years ago, and FWIW I would side more with Dale these days. It's probably a good thing we didn't just slap a half-baked API on top of SQLite and call it a we…
