Our university posted about our recent work on Bluesky :)

I finally managed to go through all the follows and messages about the #ICWSM starter pack. The first SP is full (wow!), I've added more people I've missed the first time around, and the amazing people I've met at the conference to a second one: go.bsky.app/2EFgnJV Let me know who I missed, again!

@gianluca99.bsky.social just presented their work on how Perspective API is biased towards classifying German content as toxic, and this came to mind. #ICWSM

I think you're already added, but I just re-added you :)

The weather was mostly nice, but sometimes it suddenly started raining cats and dogs. The locals seem unfazed by this. As soon as the rain lets up, they reappear on the streets, completely dry. Sometimes they even ride their bikes in the rain, still somehow looking dry.

If you have too much stuff, you can give it to the pelican. He'll gobble it up, I guess?

I also found this building. I see where they put all the corners they didn't put into those lamps.

A high-rise-ish building in Copenhagen with many spiky outgrowths.

They also have these very rounded and fluffy-looking lamps, very good.

Wispy, cloud-like lamps suspended from the ceiling.

I've noticed a few things about Copenhagen: Aalborg University has a bridge, our university does not. Pretty cool.

A bridge connecting two buildings across a waterway.

The entrance to the bridge from one building.

I actually found that feed when looking at your profile and have pinned it since :) No, unfortunately I did it manually. But there was a talk at the NextGen Social Media workshop today where they tracked academics migrating from Twitter to Bluesky: @dorianquelle.bsky.social, @abovet.bsky.social? :)

Sorry, I must have missed you somewhere, just added! :)

Only took me a few hours, but I went through the entire proceedings to find every author here on Bluesky. Let me know who I missed!

Leo Balduf @leobalduf.bsky.social · 21/06/2025

I went through the first 1k pages of the proceedings so far, working on more, bear with me. It's a lot of people to search for :)

I'll be at #ICWSM 2025 next week to present our paper about Bluesky Starter Packs. For the occasion, I've created a Starter Pack with all the organizers, speakers, and authors of this year I could find on Bluesky! Link: go.bsky.app/GDkQ3y7 Let me know if I missed anyone!

Ich als Laie frage mich: Was ist denn der Unterschied zwischen erneuerbarem und nicht erneuerbarem Müll?

Leo Balduf @leobalduf.bsky.social · 06/06/2025

Out of curiosity: What about Bluesky?

This is a test post containing !ping

Leo Balduf @leobalduf.bsky.social · 21/05/2025

What do people embed in their Bluesky posts? All sorts of things!

A table of types of embedded content in Bluesky posts and their counts. The table contains 70 rows, with many obviously invalid entries.

Nice! In the past, I stored IPFS CIDs in a database. I used hash indices, which definitely saved a lot of space. You can't do range queries with them (which is fine), and maybe there are requirements wrt uniqueness, but my keys were unique. Can definitely recommend trying!

+1 for Onshape. Never used it from a mobile browser (sounds like pain), but works very well on desktop, all OSes. They have nice tutorials, too.

Thinking about it some more, my gut feeling tells me that subscribers are probably more active than non-subscribers, simply because they engage so much with the network to know about starter packs... Temporally, their engagement might also increase simply because they see "more" after subscribing.

This comes with a grain of salt, though: IIRC this is a flag in the profile record, and I'm not sure it was there from the very beginning of starter packs. So this is a lower bound, for sure.

2) The people "using" starter packs (i.e., pressing "Follow All") are also usually people who are members of starter packs. Anyway, as such, a good chunk of the SP users is already included in the SP-member group.

Huh, no, we just didn't consider that, really. But we found two related things: 1) (so far) most (90+%) of the follow edges created via starter packs were left standing at the end of 2024. I do see the noisy timeline angle, though. I've also removed spurious SP-created follows myself before

Also: Some people really like to mess with records! There's duplicate edges, self-loops, ... all the good stuff in there 🙃

Leo Balduf @leobalduf.bsky.social · 11/04/2025

Good idea! But yeah, the complete graph is unfortunately quite large 😅 Even for the basic graph stats we have in that paper... I ran then on half a TB of memory and it took ages.

Prometheus is usually fine. You have to define your own metrics, which might take some trial and error, but the ecosystem is good. And then Grafana for visualization.
