Intro time! I'm David. I call myself a "data generalist" because I haven't found a label that fits.

I've been a software dev, data scientist, and my real passion is education so now I do Python and data training.

I'm currently most interested in skills that data people *actually* need to know.

The problem with having ideas, writing them down, and not acting on them for ages is that I have absolutely no idea what I was thinking.

I have a blog post idea written down that just says: learning "experiences"

What does that mean?????

Overconfident in everything it does, as usual 🤣

Worth reading this deeper dive into how well GenAI tools do with dataviz problems, by @nrennie.bsky.social

Wondering if you can outsource your data viz work to ChatGPT? 📊

I tested out a few different generative AI tools, giving them prompts to visualise two different data sets. If you're interested in the results, you can read them here: nrennie.rbind.io/blog/gen-ai-...

Generative AI for Data Visualisation – Nicola Rennie

Can generative AI create good data visualisations? This blog post compares the performance of ChatGPT, Claude, Copilot, and Gemini when presented with a generic request to visualise a dataset.

Very interesting! Whenever I tried it for data analysis, it did the same thing: produced *something* with no follow up questions. I wonder how well a best possible version of this would do e.g. if it had access to best practices and some more guidance. But by then you could just do it yourself!

Part of the "stickiness" of terms is how much people like to debate whether they're good terms in the first place. People will use it more if it's controversial (probably)

The videos from the #DataBS Conference have made it to YouTube!

Over the coming days, we'll highlight sessisons from the event -- one post per talk.

I think Randall Munroe made this just for you!

A chart showing "number of cuts" versus "number of measurements" with phrases like "serial killer", "surveyor", "really bad carpenter", "good carpenter", "good carpenter" and "surgeon" occupying different points. The chart is titled "Measure Twice, Cut Once - Carpentry proverb"

A blue stress ball (RIP) and a lovely notebook from the Data Science Festival (late 2021 I think). Somehow that notebook isn't full yet, despite using it for work notes all the time. A good notebook is surprisingly satisfying!

I got to round 2 of this challenge so I'm writing my second short story this weekend!

I only joined to force myself to write a bit more and I'm so happy I get to write another!

I'll post all the stories I write for this when the organisers say it's OK (a few weeks before I can post the first one).

David Asboth @davidasboth.com · Jun 21

I like writing and want to do more so I'll be taking a little writing challenge later this year.

Join me in the @nycmidnight.bsky.social 500-word Fiction Challenge on August 15th!

It was way back in 2016, I was still doing my data science Masters. Ironically, I was supposed to be preparing for a group presentation the next day but I thought I'd drive an hour to give a 5 minute talk on procrastination instead 😂

David Asboth @davidasboth.com · 8d

I haven't yet had a bad experience giving a talk anywhere. There has always been at least one person coming up to me to chat afterwards and that includes my 5 minute lightning talk I did on procrastination years ago 😂 I think people just appreciate that someone else is putting themselves out there!

So many questions. "In the same way vibe coding has transformed software development".

Has it?

Do we want spreadsheets, on which entire companies are run, being amended by something allegedly less than 60% accurate?!?

Have these companies just stopped pretending like they're launching useful AI?

Zoë “Baddie Proctor” Quinn @unburntwitch.com · 10d

Microsoft says its Agent Mode in Excel has an accuracy rate of 57.2 percent in SpreadsheetBench, a benchmark for evaluating an Al model's ability to edit real world spreadsheets. This result

I often find by the time I type up the problem in a way that maximises my chance that the LLM response will be right, I could either have written the code myself or, best case scenario, I rubber ducked myself into figuring out what I'm doing wrong.

David Asboth @davidasboth.com · 13d

How long before one of them says "some of my best friends are racists"

David Asboth @davidasboth.com · 13d

Yeah I get that they're extreme ends of the spectrum, although I suspect there are more 100% mechanists than cyborgists.

David Asboth @davidasboth.com · 13d

Cool experiment! I like the fact that some of them like GPT-5 actually kept themselves busy. Out of interest, where are you on the mechanist-cyborgist spectrum?

David Asboth @davidasboth.com · 14d

Isn't it just perfect? I show it to all my students especially when I invariably get the sense from them that they want to skip past the "boring data cleaning" and do the "fun machine learning". Boy, does the real world have a surprise for them!

People would have to speak anonymously to protect their identity 😂 like those news programmes where the interviewee is just a shadow or a blur and their voice is put through a Darth Vader filter

This is frankly the problem with practically every digital project ever conceived. Today the discussion is about digital IDs in the UK which sound like a NIGHTMARE from a technical perspective before we even consider all the other implications. No way it ends well.

ohgodwhatdoiput.bsky.social @ohgodwhatdoiput.bsky.social · 15d

the implementation will not be well thought through or correct though.

David Asboth @davidasboth.com · 15d

Wasn't there something about COVID affecting people's brains in a way that they become less empathetic? I haven't read the research so it may be BS but it could help explain why *now*

David Asboth @davidasboth.com · 18d

ALL THE DAVIDS. Funny, I'll be ending my day with my talk (9pm in the UK) just before you start your day with yours! Looking forward to it all.

This is what we Hungarians co-opted and call "Hungarian cards". Lots of interesting games available with them.
