It's kind of infuriating how, as soon as you try to do good, you're held to impossible standards. People are shit and companies are shit all the time and nobody bats an eye. But do volunteer work for your FOSS community, start a project that tries to do things more ethically, just be visibly not shit, and people left and right come out of the woodwork to point out all the ways in which you are not being absolutely flawless and perfect, and all the work that needs doing that you're not yet taking upon you. The people actually doing the work are also the people who are being asked to do even more, and who are being critised the most. It's a really insiduous pattern and we all need to be better at recognising it and squashing it.

This has really been on my mind. Cause in a way it's blindingly obvious. You read that and you go "yeah we knew that". But it really drives the point home. People didn't choose AI. Companies didn't choose AI. Governments didn't choose AI. A small number of people, controlling a small number of entities, controlling unfathomable amounts of money, chose AI. Went all in. And the sheer capitalist force of that made it inevitable, made it an undeniable reality. Made companies and governments and individuals fall in line. I hope we, as a species, can claw our way back from this. From people with no democratic mandate having this much power. If so this will be studied in the history books. Probably not in my lifetime. https://graceblakeley.substack.com/p/data-centres-and-democracy
We didn't choose AI. Capital did.

The AI boom was planned by capital. When it collapses, capital must be made to pay.

Pro-tips for anyone creating an address form.

ZIP code is not a generic English term for postal code, but instead a very specific USPS thing (it stands for Zone Improvement Plan). If you serve anyone outside the US of A, call it "Postal Code".

Not every country has states, don't make it a mandatory field.

Many, many more nuances to international addresses, but these are the ones that bother me most as a Belgian.

Something I've only come to appreciate recently.

When an engineer hears "tech debt" they hear "bad". You don't want to go into debt if you can help it. It makes you anxious. You want to pay it off ASAP.

But for business folks debt is just a tool to enable more growth. Debt is good, it's essential. You pay it off from future growth, or roll it over. But tech debt doesn't work like that.

I think this leads to a lot of miscommunication and frustration.

RE: @marijn@mastodon.social

Instead of trying to change ProseMirror to incorporate these new insights, I have chosen to create a completely new system with a new name. A ProseMirror 2.0 with an incompatible interface would amount to the same but make it ambiguous what people mean when referring to ProseMirror.

This is the way, people! I know your project has built up all this clout and name recognition, but if the new version is really a rewrite, or a significant re-architecting, then make it a new project. Let the old one live out its days on its own merit, don't force people to "upgrade" (migrate, really). Don't sow confusion. Names are cheap, you can have as many as you like!

The longer it sits with me the more the commodore phone pisses me off. Browser: blocked. Social media: blocked. We don't need lobotomized nostalgia machines, we need devices that give the user the power to shape their experience. Operating systems designed with human wellbeing in mind. Calm, powerful technology that grants agency. This is worse than a toy.

(And we need to keep big tech accountable for their harmful products, but that's another story.)

Anecdotally, from talking to a lot of people in person at Dutch Clojure Days, my impression is that, at least in this community, the number of people who practice or believe in full on vibe coding is very small. The number who categorically don't engage with AI is also very small.

The vast majority seems to use some LLM tools for coding at least semi-regularly, and think it's useful at least for some things (not always agreeing on which things). There's huge variation though in how much and in what way it's being used.

Still, the general sentiment seems to be mostly negative. There are ethical and environmental concerns, worries about jobs security, but also just a sense that it's unsatisfying to work with, with frustrating, mediocre, and inconsistent results. People who have to use it at work expressed that code review is now the bottleneck, and that they can see their codebase deteriorating week by week, with more duplication and inconsistencies.

This is all very anecdotal, so make of it what you will.

This is the kind of AI discourse I would love to see more of. Grounded in research and reality, practical and centered on outcomes.

Shaming and stigmatising people for their LLM use may feel justified, but it'll lead to the opposite outcome of what you want to achieve. Meet people where they're at, and focus on AI literacy instead.

(Please don't engage with this point unless you've watched the video. Yes it's long, it took me a few sessions, it's worth it.)

As I agonise over these docs I ask myself, will anyone read this, or will they just ask claude?

I already noticed this at my previous gig, reading comprehension, and the willingness to focus on a non-trivial piece of writing, just going down the drain. Just copy-paste it into chatgpt, skim the AI summary, move on.

Reading technical docs is work, it takes effort and concentration, but you get rewarded with new skills. A good writer can make the reading easier, but there's a lower bound beyond which you sacrifice too much rigor and precision.

Two very senior engineers, pairing for over an hour, to figure out that a function call had its first two arguments in the wrong order.

I'm not sure what the moral of this story is. Maybe it's that stupid stuff will trip you up, no matter how experienced you are. Or that positional arguments were a mistake. Or maybe that meatbags weren't meant to code and we really do just need to hand it all over to the AI overlords.

Made myself a profile on https://couchers.org/, in preparation for an upcoming travel adventure. I was big on Couchsurfing in my 20s, but Couchsurfing was also one of the first sites that enshittified HARD. A community built by volunteers, sold to private equity, and locked behind a subscription...

But anyway, there's a few other hospitality exchange (hospex) platforms that tried to fill the gap, notable BeWelcome, but Couchers really nails the vibe of the old CS and seems to have a good amount of profiles.

@toxi@mastodon.thi.ng this is really interesting cause I'm thinking now, what if I had actually posed that question to some of my clients? I can think of a few who probably would've chosen the ship-at-all-costs model. I think these are also the same people who would be incredulous a year later that team velocity has dropped to close to zero. Not many appreciate how high the interest rates are on this stuff, until all of a sudden they're breaking more in a sprint than they are shipping.

#berlin peeps, I'm looking for someone who wants to sublet their place the last week of August. August 21 to August 30th or thereabouts. It's for me and possibly my partner. Non-smokers, no pets, responsible people who go to bed early. Lmk if you know of anyone who's leaving town around that time. Vielen Dank!🙏🐻

I did a write-up of the tools and tooling we used while organising Heart of Clojure 2024.

Is anyone aware of similar posts from other conferences, especially community/open-source events?

Are there organisers on here that want to share what their stack and process looks like?

@daveliepmann @jack AI mandates are pretty common, so clearly some people need to be coerced. Looking at how this post went viral I'd say there's a significant group that isn't interested, regardless of whether they work. But people fear their employability if they publicly say that. With regards to "it works", I'd love to see more nuance in the discourse. What kind of software are you building? What's your workflow like? Are you being honest to yourself about how much more productive you are (vs feel)? Is it a satisfying experience? Do you feel pride in "your" work? Do you understand what the code does? Etc. I have used it and probably will use it more in the future, but in a particular, limited way, and with specific constraints about where I get my tokens from.
