Anyone in the UK getting extremely slow resolution from
@quad9dns.bsky.social at the moment? Currently seeing queries taking up to 3.5s, with more than a few timeouts for good measure :/

I’ve just realised that my 15 year self-employment anniversary managed to sneak by uncommented yesterday. I keep thinking that I should write about the whole thing at some point, but there’re so many folk who’ve written about it, I’m not sure what more I can add.

Been using Apple Music a lot more after watching @jjbbllkk.bsky.social’s recent video about Spotify.

Anyone know who I can harass at Apple so they actually fix the prev/next track functionality when using shuffle. Such a basic bit of UX that has been unusably broken for too long…

Creative folk who’ve ditched the Adobe stack: what’re your favourite Photoshop replacements?

I’ve been trying to love the Affinity suite for about a year; Designer and Publisher are fine, but while Photo has some nice touches, I just… don’t love it. I’m curious as to what other folk are using.

Heading back home after three days cosplaying an extrovert at a trade show with/for a client. It’s been incredibly tiring but a lot of fun. Got a laundry list of things I/we want to do as a result, but first I need to lay down and not move for at least 12 hours.

Oh great: my train has been ‘upgraded’ to a Voyager. I wonder how well this one has been maintained…

Any #cssday folk still in Amsterdam up for food/drinks/discussing the shape of the web this evening?

… dear gods of bsky: can we have post editing, please? I might possibly have gotten a little too used to it on masto, and it would save the amount of post-delete-repost cycles I go through 😆

To summarise the past couple days at #cssday for the bsky folks: wow! I expected it to be good, and I was very much not disappointed.
Also very glad that I’m also taking next week off so I can mess around with all this cool new stuff! :D

Will definitely be back next year, see y’all then!

I forget who I was talking to at #cssday yesterday about poisoning AI via YouTube subtitles, but here’s a video explaining how it works in any case :)

(I wonder if there’s a way of doing something similar on the web, but without completely screwing over AT users)

Back at my hotel after #cssday day 1: lots of notes of things I need to read up on/play with, and feeling pretty darn good about the web (again). Plus connecting with folk is always good.

Now sleep, then back for day two! #devLife #zzzzzz

Also, those wanting to maximise their #FOMO and follow along through the medium of short-form posting, @joshtumath.uk will almost certainly be posting like a madman!

(also, there’re livestreams, but… y’know)
Back again! #cssday

(will be occasionally posting to Mastodon; if you see me come say hi! #notUnfriendlyJustShy)

Back when I was finding my feet in tech everybody was buzzing about building positive change. Somewhere along the way, something changed. Fortunately for us though, tech is not the first industry forced to defend itself against dubious practices.

What might we learn if we were to look elsewhere?
Looking elsewhere - Robb Owen
Against the backdrop of mass layoffs, LLMs, site-builders and vibe coding what does it mean to conscientiously build for the web, and where do we go from here?

Hello. Your Jewish pal here. Antisemitism is becoming more difficult to define. This is deliberate and intended to alienate us from the oppressed people with whom we should be making common cause.
This - from the former Prime Minister of the UK, no less - is *dripping* with coded antisemitism.
In case you missed it in The Other Place, Liz Truss has gone properly fucking nuts.

So apparently when the good folk at BBC Good Food rebuilt their website, they seem to have forgotten that people might want to print recipes out.

What used to be a single A4 page (with 2x ads) is now 3 sheets; complete with 2 sets of tags, star ratings, alternative recipes (!) and whitespace.
