yeah, I absolutely do not get it. The irony of it being a 10 second job to swap to a VPN too...how much effort has been spent on this thing that is easily avoided?!

Thought it was weird I hadn't had a DM reply from someone and then I realised I need to verify my age ๐Ÿ™„

It's time for modern CSS to kill the SPA Native CSS transitions have quietly killed the strongest argument for client-side routing. Yet people keep building terrible apps instead of performant websites.

โ€œThe reason SPAs became the default wasnโ€™t because they were better. It was because, for a while, they were the only way to deliver something that felt fluid โ€“ something that didnโ€™t flash white between pages or jank the scroll position.โ€

Really awesome blog post! The perf extensibility API is really cool (although I am biased...) and worth your time to add custom data to the performance traces on your sites.

Also, the issue Harry mentions where marks don't show timestamps is absolutely a bug, and will be fixed in Chrome M140.

@csswizardry.com hey! Thanks for your blog post on the extensibility API :)

One thing stood out - you mentioned that timestamps are not shown for markers, which I agree is unhelpful, so I've fixed it in crrev.com/c/6787872 and after that lands, timestamps are shown on hover + on click :)

Currently have two large 28" monitors, one landscape, one portrait, but quite close to going back to just one larger (32") monitor...but will I miss the extra space?!

I have just moved from Google WiFi to Deco as when we moved house Google struggled. I've been so happy with the Deco system. It's much better at dealing with thick walls and interference and was easy to set up. Highly recommend.

UK Prime Minister needs to get off Twitter/X and stop stoking race hate. Instead focus on improving living standards for citizens. People working hard in precarious delivery roles are not depriving others of these aspirations! Christ

hahaha, I'm actually weird and have a set of about 10 fonts I loop between, and wrote a script to pick a random one and apply it to my config :D github.com/jackfranklin...

`typeof null === 'object'` so I think you might need to check for null. And then I tend to find 'a' in x more reliable in TS

nope! Just taken a couple of days off to do some sorting, we only moved house in February so there's still some lingering mess and moving boxes :D

hahah agreed, my major result is that Leo loves the model railway so in my head I can work on it and spend money on it and be a good father all at the same time!

Really embracing fatherhood, took a day off to spend clearing out the shed and going to the model railway shop ๐Ÿ˜‚

I'm not skeptical of LLMs having utility, but am I skeptical of the hype and the amount it's being sold as the solution? Yes. And I use them every day!

if they started maintaining it and shipping updates, I would sign up to Supermaven again very quickly

hey! I use Github Copilot now. It's definitely not quite as good, but good enough and I am fortunate enough to get a license for free because of my open source contributions. Supermaven was fantastic but their lack of care on the repo means I'm not willing to pay money until they maintain it.
