A Return to Fun funfun.email/p/return-to-...

Biggest commitment to a 3 second joke I've ever seen

I am reading Daniel Levintins excellent book ”The Organized Mind” and this part perfectly explains why I sometimes get stuck in multi-hour obsessive TypeScript rabbit holes to create the perfectly (unnecessary) typed expression for a problem.

I love this format with @bashbunni.dev and I hereby promise publicly to try doing this. Also I so love the aesthetics and idea @charm.sh, makes me feel super great for some reason www.youtube.com/watch?v=Qpz0...

hmm should I make a Rough Regex course after my Dirty D3 series ends (in 2054)

💛🌻🎉 #dataviz

💛It’s seldom one gets shoutouts for commercial partnerships, but @augmentcode.com really is that good - it’s really an incredible thing that a platform targeting large legacy codebases is free for OSS thx @adrienjoly.com

New episode! 📽️💛 What is interpolation, really? | Dirty D3 - Episode 3 youtu.be/LOaqG--VWas #dataviz #d3js

I'm obsessed with this: Mystical, a visual representation of PostScript as magical symbols. What if software departments were catacombs of hooded figures scratching arcane circles into the dirt github.com/denismm/myst... (via @piterpasma.nl)

I love love love this example, really visceral way of unstanding variance

Great thread on dataviz animation ❤️

Humanity may never be able to find a counter-example to Collatz conjecture if this package gets removed from npm.

We often mind-wander about our past, present, & future. What happens when our minds drift towards our bodies? In a new fMRI study (n ~ 500), @leahbanellis.bsky.social + team discovers unique neural, affective, & physiological correlates of "body-wandering" at rest. www.biorxiv.org/content/10.1...

Me in the WSJ today, arguing that the relationship between social media and mental health is not clear cut, and bans for teenagers aren't the answer. (NB I did not pick this title, I would have gone for something kinder. I understand why people are worried.) 1/ www.wsj.com/health/welln...

New manuscript published! ✍️👀 Concept neurons evolve from index neurons through overlapping memories. Check it out here: www.cell.com/trends/cogni... 1/15

Can what you eat change your mind? 🍎 My first piece in @theguardian.com on why we like what we like, and the role the gut might play in mental health. Hint: it’s probably not all about the microbiome.

I find it so lovely that @augmentcode.com uses the separate domain name hkjl.ai for their @neovim.io integration 💛💛💛 much poise #neovim

This beautiful video by Kurtzgesagt voiced by @johngreensbluesky.bsky.social captures well why I like following the Green brothers. LFG in an orderly fashion. www.youtube.com/watch?v=GFLb...

If you're curious about coding-assisted platforms (but tired of the hype and unfulfilled promises), have a look at this video about Augment Code. Maybe, just maybe, this is for you :) #aifordevs #aicoding youtu.be/LEOSWYlQyVw?...

If you're into D3 or Observable, there is no doubt you ran into Fil at some point. I learned a ton from him, and this interview only adds to that

I'm super duper proud to officially announce the FFF partnership with @augmentcode.com, the developer AI that I've been using as my primary for the last few months. Go give it a whirl using fff.dev/augment and let me know what you think!

good monday morning #dataviz bluesky, I just dropped a new Fun Fun Function video: youtu.be/aAP3m0PyGrY

 'Line Plots are Plot Lines' 
 (a data visualization spoken word 
cover of funfun.email issue #12)

New article by me! It's a common mistake to think the TFR is a prediction of the average number of children women will have over their lifetimes. But it's not. The TFR can decline even when the eventual number of children per woman stays constant or even increases; the opposite can happen too. 🧵

This wonderful man, @rshean.bsky.social, has written what Shakespeare would have, had he been working with Excel at scale* *= “scale”

This was sort of foreshadowing youtu.be/ohDB5gbtaEQ?...

Sleep well

Can you please explain #PowerBI to me? Wrong answers only.

Very exhaustive test of Claude interpreting graph, fun to read!

I like how well highlighted this was:

So it is trained on your uncle on Facebook?

I mean yes

Just because you can, you should

This was much news to me. Lots of interesting aspects with this article, but the detail that concept cells fire only after a 300 ms delay, for some reason, stuck out for me.

It's that time of the year again. #SuperBowl 📊

Saturday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data) • about 790,000 km² below the 2010s mean • about 1,450,000 km² below the 2000s mean • about 2,040,000 km² below the 1990s mean • about 2,430,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...

Generally not posting political stuff but I found this opinion piece by @ezrakleinbot.bsky.social to be an interesting and calming take, and elucidating on what is going on in the media space. www.youtube.com/watch?v=K8QL...

Really looking forward to listening to this new investigative pod series by @suelinwong.bsky.social. I was made aware of this fascinating (and unnerving) phenomena through @pjvogt.bsky.social on the episode pjvogt.substack.com/p/whos-behin... and this seems like a much bigger deep dive.

This was incredibly interesting, look at the video first and inspect your own response before reading further into the article, that makes the article a lot more interesting. www.effaff.com/the-data-sto...

Astonishing article in today’s FT on the private parking industry. Of course, private equity is involved.
