Data engineer and full-stack web person since the late nineties; these days mostly UK property, geospatial and broadband data, DuckDB, Parquet and more H3 hexagons than is strictly healthy.

I run CrimeRate, an independent UK crime statistics platform that tries to do street-level crime rates properly so a quiet cul-de-sac with three incidents doesn’t get painted as a hotspot, using walking-distance isochrones instead of arbitrary admin boundaries, and counts stored first with rates derived as late as possible. Always happy to talk spatial stats, messy public-sector data, or why most crime maps are quietly lying to you.

Most of what I build ends up named after cows, which you’d reasonably take as a nod to treating servers as cattle rather than pets, and it took me an embarrassingly long time to notice I’ve been doting on every one of them like the family dog; tom@moomoomoo.com if you want to say hello.

Also, these days, a terrible pianist; classically drilled at sixteen, accidentally fluent at sight-transposing thanks to an electric piano with a stuck middle C, forever pining after Rachmaninov and properly in love with Brubeck, and once upon an A-level I could get through Blue Rondo à la Turk intact, though what comes out of me now is more of a nervous 9/8 stagger than anything Dave would recognise.

mootothemax··on Inventing Cyrillic (2024)
I think I may have fallen victim to a GP midflight edit - I agree with you fwiw, it’s a stone cold fact.

> Germans are Nemci in Russian as well

I wanted to check; are you implying that Russian is not a Slavic language?

Makes sense given Welsh’s evolution from Britannic. Much to my shame, I only started visiting Wales in later life, and there’s really something in the language that grabs me quite deeply. Once I’ve got my Polish down to pat, I tell myself.

It’s lovely isn’t it? There’re a good few of these things around: notably Torpenhow Hill (which killjoys dispute); and ones like Pendle Hill (which they don’t).

If you can find a way to combine this with local population to end up at pence per litre per thousand population, I bet you’d uncover some fun trends. Bet it’d also get interesting if combined with population within an X min drive too.

Tho really need some car population per road segment stats to drive the most out of it IMO.

Welsh for river.

mootothemax··on Six Years Perfecting Maps on WatchOS
> With Maplibre or any modern map SDK this this is standard…

In practise, this doesn’t work out as visually pleasing as you’d like; labels repeat, or render partially or not at all, or become interfered with by other labels, or only work well at one given zoom. It’s easy to end up in a visually dissatisfying place that’s taking an unfathomable number of magic rules to get to.

The secret sauce to fixing this is creating separate label layers of perfect point locations or lines for labels to follow in advance. Added bonus is faster render and interaction times due to fewer rules.

I long for the days where it’s only my moral compass holding me back.

Thanks for your thanks! Let me know how you get on, I’d love to know if this is a secret knowledge thing that turns out to work for other people too.

For what it’s worth, I cancelled my ChatGPT subscription, and every time I try debugging a Linux system issue, I feel sad that Claude is sooooooo confidently bad at it.

Claude is noticeably poor for my use case on this particular issue. That said, I imagine I’m not alone in refusing to continue paying OpenAI. We’re in for a wild ride.

mootothemax··on I've been waiting over a month for Anthropic to respond to my billing issue
Completely by accident, I have a setup that sends a pdf invoice to customers a couple of days after the sale. I’m pretty sure it’s a stripe option I must’ve misclicked.

Anyway- turns out that on the rare occasion someone’s had an issue, this gives them a really easy mechanism to write to me and tell me about it. They let off their steam in the email and then we make things good together. (Yet another reason why I always oppose noreply email addresses)

I still don’t know what or where the setting is, mind.

mootothemax··on GPT-5.4
Huh, that’s interesting, I’ve been having very similar thoughts lately about what the near-ish term of this tech looks like.

My biggest worry is that the private jet class of people end up with absurdly powerful AI at their fingertips, while the rest of us are left with our BigMac McAIs.

For context, BERT is encoder-only, vs SLMs and LLMs which are decoder-only, and BERT is very much not about generating text, it’s a completely different tech and purpose behind it. I believe some multimodal variants nowadays may muddy the waters slightly, but fundamentally they’re very different things, let alone around been around for decades unless also including the history of computing in general.

While I could’ve written that better and with less attitude, gotta confess - and thx for pointing out my smugness - the AI stuff of the last few weeks really got under my skin, think I’m feeling all rather fatigued about it

mootothemax··on Microgpt
> > BERT isn’t a SLM Huh? BERT is literally a language model that's small and uses attention.

Astute readers will note what’s been missed here.

Fascinating, really. Your confidently-statement yet factually void comments I’d have previously put down to one of the classic programmer mindsets. Nowadays though - where do I see that kind of thing most often? Curious.

mootothemax··on Microgpt
> We had good small language models for decades. (E.g. BERT)

BERT isn’t a SLM, and the original was released in 2018.

The whole new era kicked off with Attention Is All You Need; we haven’t reached even a single decade of work on it.

For myself, it’s the feeling of: thank fuck; the grownups have arrived. shoulders lower, everyone takes a deep breath

mootothemax··on UK government launches fuel forecourt price API
It’s a delight even to have a regulated source of all fuel station locations in the uk!

This might be a slight missing woods/trees moment but that aside - there is precious little open geospatial data in the uk that establishes see this dot here? That’s a fuel station, that is. That dot there? Oooooh no, that there’s a pub.

The uk govts of the time managed to hand both the address data and the this-is-what-it-is data off to separate commercial enterprises in the name of privatisation, and I genuinely believe it was by accident as it’s… err… quite a niche topic of knowledge.

So anything - anything! - that brings some of that back and truly open to the public is very much welcomed.

I guess this is what makes marketing so tricky; I myself would’ve bought a $10/mo subscription so much sooner given the chance, which by now - and happily, incidentally - would’ve brought in way more dosh than my one-off payment.

That’s an excellent point, thanks for linking.

My takeaway from this thread is: his theory’s great until you discover that your customers are wiling pay *so* much more.

On a more positive note, I’ve been blown away by the (largely, one conspicuous troll-like annoyance aside) positive thoughts in the comments. Maybe it’s not too late?

mootothemax··on OpenAI's cash burn will be one of the big bubble questions of 2026
While I don’t disagree with you, for historical purposes I think it’s important to highlight why google started its push for 100% wire encryption everywhere all the time:

The NSA and GHCQ and basically every TLA with the ability to tap a fibre cable had figured out the gap in Google’s armour: Google’s datacenter backhaul links were unencrypted. Tap into them, and you get _everything_.

I’ve no idea whether Snowdon’s leaks were a revelation or a confirmation for google themselves; either way, it’s arguably a total breach.

This is pretty much well what is so remarkable about parquet files; not only do you get seekable data, you can fetch only the columns you want too.

I believe that there are also indexing opportunities (not necessarily via eg hive partitioning) but frankly - am kinda out of my depth pn it.

Hi there - I’m really sorry about your negative experiences. I read the replies to your comment and felt sad that I didn’t read one that recognised how much work you’re putting into what sounds like an indifferent society - and how unfair that is. I also hope I’m not crossing the line of too much/trying too hard. Frankly, it sounds like a shit place to be.

mootothemax··on I took all my projects off the cloud, saving thousands of dollars
> Just one of the couple dozen databases we run for our product in the dev environment alone is over 12 TB.

> How could I not use the cloud?

Funnily enough, one of my side projects has its (processed) primary source of truth at that exact size. Updates itself automatically every night adding a further ~18-25 million rows. Big but not _big_ data, right?

Anyway, that's sitting running happily with instant access times (yay solid DB background) on a dedicated OVH server that's somewhere around £600/mo (+VAT) and shared with a few other projects. OVH's virtual rack tech is pretty amazing too, replicating that kind of size on the internal network is trivial too.

Is it that common to upset people at work and have absolutely no clue why or how or what you’ve done?

And not from a lack of trying, and definitely not because you don’t care?

Because to me, that’s what masking means: constantly checking yourself because you do care, and you do like people, and the last thing you ever want to do is hurt or upset someone, and yet sometimes you do, and that sucks, and you learn from it, file it away in your mind for next time, and wake up the next day with the same happy-go-lucky optimism you do every day until the world beats it out of you.
