I tend to get this with people who haven’t heard the ”we only use LLMs for things you understand well enough to fact check” talk. The worst was a case of a researcher who had *two* stats people telling them something cannot be done and who tried to counter by sharing a chatGPT chat screen shots..

This is close to my #1 pet peeve: the "if I can do it, you can do it" people. Almost always they start from a major position of unacknowledged privilege that it makes me want to scream. Like, good for you that you fit into the round hole! Still doesn't mean everyone else can.

When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

It says in that piece that the source for concern would be the cyber attacks against Polish energy infrastructure last December (whose source is thought to be Russia). Not clear based on reporting if there is any concrete acute threat.

This skeet brought to you by a very snippy PhD student response to very reasonable coauthor comments because the student is trying to submit by a supervisor suggested (entirely imaginary) deadline.

Dr Juulia Suvilehto @juulia.bsky.social · 24/02/2026

Why do so many academics keep saying "let's try to submit this next week" when everyone can clearly see that the manuscript is not ready? I see many PhD students so stressed out about this when no one tells them "next week" deadline is aspirational, and not actually a real deadline. #AcademicSky

Thanks for a really interesting paper! I would love to take a look at the supplementary material but I can't figure out how to access it. Is that a separate file somewhere? If yes, would you be kind enough to share the link? 🙏

I tend to go by: if I saw them sitting alone in a cafe or a bar, would I go join them or would I find a table of my own? Works for online folks but also imposes some limit of how much I need to like that person in order for them to ”count”. I suspect that that limit scales with introversion though

Great talk by @hollycummins.com at Lindholmen developer day. As a data person and as someone who used to work with healthcare this resonated a lot: "don't make human tell computer things the computer already knows". It is so key but so often neglected in practice (&definitely a thief of joy) #databs

A photo of a woman in front of a large presentation. On the slide she's presenting, it says
The new paradigms
Joy has business value
Get rid of dumb work
If you can't get rid of the work, make computers do the work
Don't make humans tell the computer things the computer already knows
Get rid of flab from the programming model
Measure the important metric, not the one that's easy to measure

My best tip is to be very ruthless in having rules for email that automatically gets cleaned out of the inbox, e.g. automatic emails from systems, stuff that gets sent out as FYI, weekly XYZ digests etc. They all go into their own folders and I look at them if/when I feel like it. Maybe never.

Dr Juulia Suvilehto @juulia.bsky.social · 08/10/2025

In my old job I would get around 20-30 emails per day that required me specifically to react to them (so, no automated emails, no mailing list stuff). In my new job, so far ✨almost nothing✨. But I think email volume is likely a function of your tenure and/or network centrality in an organisation.

Thank you everyone for your suggestions! This is how I ended up plotting my LLM system output vs human annotation vs LLM-as-a-judge evals. Extra thanks to @libbyheeren.bsky.social for boosting my original question. #databs #dataviz

Four bar plots arranged like a confusion matrix. Bars have two colors stacked, based on evaluator output. Plot shows that the evaluator (DSPy optimized + got-5-nano) flags many false positives and false negatives and does not flag that many true positives or true negatives.

A barplot with three series of two bars each. The series are different evaluation frameworks: Phoenix, deepeval, and DSPy. Of the pairs of bars, the left one displays evaluation output when original rating was incorrect and the right one displays evaluation output when original rating was correct. The color of the bar shows evaluator output. The plot shows that DSPy (non optimized) performs best, ie tags most incorrect responses and does not tag many correct responses.

Wow, thank you so much @thoughtfulnz.bsky.social ! That's really pretty & so nice of you to make up a toy example! 🤩🤩🤩

010

Dr Juulia Suvilehto @juulia.bsky.social · 30/09/2025

Ooh, that's a thought! Thanks! I think it's good for the audience to have a sense of how prevalent true vs faulty answers are, but that doesn't necessarily need to be in the same plot as the comparisons 🤔

100

Dr Juulia Suvilehto @juulia.bsky.social · 30/09/2025

Thanks Libby! Something like this is what I'm leaning towards but with four sections (so that I can show false positives and false negatives separately, they have different business implications)

200

Dr Juulia Suvilehto @juulia.bsky.social · 30/09/2025

Fair point! Right now I'm just going : right answer is the one a human gave + false positives and false negatives have different cost (false negatives are much more costly than false positives)

Dr Juulia Suvilehto @juulia.bsky.social · 30/09/2025

Oh hey thanks, I hadn't really thought of radar plot for this! That's definitely worth considering!

110

Dr Juulia Suvilehto @juulia.bsky.social · 30/09/2025

I think the problem is that data science is >10% thinking and you can't really externalize the thinking, just the execution. And even for execution you need to split in suitable sized chunks that you quality control yourself.

Dr Juulia Suvilehto @juulia.bsky.social · 29/09/2025

I’m really loving it for making and tweaking plots where I kind of know the plotting library but not well enough to remember all the functions and params by heart. @hadley.nz had a wonderful demo of this at the Posit conf earlier this month, it might be on youtube soon!

Dr Juulia Suvilehto @juulia.bsky.social · 29/09/2025

Maybe sometime down the line! Right I have a number of evals coming from many different models & frameworks and need to figure out how to best visualize them for our dev team.

000

Dr Juulia Suvilehto @juulia.bsky.social · 29/09/2025

Any references for good visualizations of LLM evals? We have orig system output (yes/no), a human annotator's y/n and a number of different y/n evaluations. The aim is to see how good our original system is and how much of the issues do the diff LLM evals catch. How would you visualize this? #databs

My mentor once said: strongest results are the ones where you don't even need stats to figure out if there was an effect, you just plot the raw data and look at it with your two human eyes. If it's obvious then, it's a ding-dang strong effect.

Academics, get thee some fuck off skills. Marketable skills that can help you fuck off from academia and get employed elsewhere. I see folx do multiple postdocs because they don't know what else they could do. Don't let that be you - make sure you have the ability to fuck off #academia #AcademicSky

I seem to re-learn this truth at regular intervals: if you're looking for an explanation of how something slightly niche works, find a master's thesis related to the topic. Students (at least in the nordics) are expected to explain the whole thing and not leave steps out (unlike academic articles).

000

Dr Juulia Suvilehto @juulia.bsky.social · 23/04/2025

Ok that's a very good point! Could it be that since knowing how to do something in python is such a small part of a data scientist expertise it's just not something that is a strong part of our identity? Like, I wear clothes every day but I would never call myself "a real fashionista." Cause 🤷‍♀️

010

Dr Juulia Suvilehto @juulia.bsky.social · 23/04/2025

I think there's a subtle difference between saying "I can bake" and saying "I'm a real baker". Like, the latter feels like taking ownership of something that maybe someone else has a stronger claim over (pro bakers) whereas I can make a birthday cake but I'm not a professional baker.

100

Dr Juulia Suvilehto @juulia.bsky.social · 23/04/2025

Also isn't Python supposed to be a fairly opinionated language? I use Python in a very pragmatic way and am not always sure if the way I'm doing things is 100% the pythonic way and that feels like something a "real Python user" should know.

100

Dr Juulia Suvilehto @juulia.bsky.social · 23/04/2025

Hahahaha, I so recognize myself in this. For me it's because I am surrounded by teams who use Python to build infrastructure and I don't for a moment think that I could do their jobs. So I feel like I must be a lesser Pythonista somehow.

I was studying at the uni and we had programming courses where you could get support from the TAs on the course's own IRC channel. I used Google reader to keep up with my favorite blogs. There was so little fluff or ads on websites, it was just raw html and original, stellar content 🥺
