When someone says โ€žScientists do not want you to knowโ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They canโ€™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.

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? ๐Ÿ™

It looks like that thatโ€™s how the 150 circle (โ€meaningful contactsโ€) of Dunbarโ€™s number is inofficially defined, I must have picked it up from there..

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 โ€countโ€. I suspect that that limit scales with introversion though

I went to Metallica gig with a group of professors and, I mean, they werenโ€™t active participants in the mosh pit but they were *right* next to it. yes, theory was discussed.

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

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

Hahaha, ok so it's an avalanche of spam and very little ham it sounds like. That sounds better than the inverse to me actually ๐Ÿ˜‚

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.

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 โœจalmost nothingโœจ. 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

Wow, thank you so much @thoughtfulnz.bsky.social ! That's really pretty & so nice of you to make up a toy example! ๐Ÿคฉ๐Ÿคฉ๐Ÿคฉ

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 ๐Ÿค”

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)

30.09.2025 06:17 ๐Ÿ‘ 0 ๐Ÿ” 0 ๐Ÿ’ฌ 2 ๐Ÿ“Œ 0

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)

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

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.

Iโ€™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!

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.

29.09.2025 14:25 ๐Ÿ‘ 0 ๐Ÿ” 0 ๐Ÿ’ฌ 0 ๐Ÿ“Œ 0

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.

Hi! Just wanted to let you know that there seems to be something wrong with the link - I get an 404 page when trying to open it and cant find the blog even in the blog tab.
