This is an incredible post and I learned a lot.

Side-note: @samwho.dev's blog posts and visual explanations continue to amaze me!

I think it's slightly different but that might be because I'm more skeptical of the long term success of AI as the primary code author in large complex systems, but who knows what will happen 😁

I've been thinking about this for a while; if* AI generated code becomes the norm then our code review tools and processes are woefully inadequate.

* Still think this is quite a big if

I'm talking specifically here about the 100k cliff but yes I take the point 🙂

However if we are looking purely at salary take home then yes you're obviously correct that a pay rise in isolation never means less take-home

A lot of UK earners at just over 100k are advised to put into pension to bring their post pension income to below 100k to access childcare benefits which they wouldn't get otherwise

If I understand correctly there are some cases where going off the childcare threshold cliff in the UK does mean your effective take home (once you pay for nursery) is reduced vs a lower salary with childcare benefits

The Pebble Index is a really compelling idea and I think I'd love the mental offloading but it's such a shame it's not got a rechargeable battery and is then disposed 😔

you can also end a line with \ and then hit enter, I think.

This is just like...really rubbish right? It's horrible to watch and especially if you look at the movement of the people and objects, and the details.

It’s been a very hard year - Andy Bell Unlike a lot of places in tech, my company, Set Studio/Piccalilli has no outside funding. Bootstrapped is what the LinkedIn people say, I think. It’s been a hard year this year. A very hard year...

A bit of a vulnerable post by me but we need your help to get us through what has been a more difficult period than 2020.

It would be really appreciated if you could read and share in your networks too 💛

What is fatherhood? - A dad who writes

Nearly two years ago I became a father and whilst I wouldn't change it for anything, it's also been a hugely challenging two years for me and my wellbeing.

Turns out writing about it helps, and I hope maybe it might help others: adadwhowrites.com

What do people use these days for lightweight analytics of visitors to a web page? It's low traffic so ideally a free or very cheap plan would be best - I don't need anything too complex! Basically just need to know visitors per URL on one domain.

Save performance trace options:

Save performance trace options: - Include annotations - Include resource content - Include script source maps - Compress with gzip

Chrome 143 will start rolling out today (most users get it next week).

It includes a new set of options for your webperf traces — including saving sources & source maps:
developer.chrome.com/docs/devtool...

This makes it easier for those viewing traces outside of the page load to get more context.
