I went to check out leaflet.js after seeing it mentioned as one of the options for interactive map features. And after opening the homepage, I now must use it and support it: https://leafletjs.com/
I love the last paragraph in the pop up:
"If you support the actions of the Russian government…

I'm a fucking Anarchist, and I’m not shutting the hell up! Stop trying to convince me otherwise. If you don’t like my path and my knowledge, then I have a damn good option for you!
Move the fuck on with your life. Find new friends, meet new people, connect with those who share your interests. Stop wasting your time trying to change me.
Fuck off telling me to vote in some bullshit election. Stop trying to talk me out of anarchism and revolutionary syndicalism. I’m done with th…

On the Farrell--Tate $K$-theory of $\text{Out}(F_n)$

On the Farrell--Tate $K$-theory of $\text{Out}(F_n)$
Using Lück's Chern character isomorphism we obtain a general formula in terms of centralisers for the $p$-adic Farrell--Tate $K$-theory of any discrete group $G$ with a finite classifying space for proper actions. We apply this formula to $\text{Out}(F_n)$. The case $n=p+1$ turns out to be especially interesting for the following reason: Up to conjugacy there is exactly one order $p$ element in $\text{Out}(F_{p+1})$ which does not lift to an order $p$ element in $\text{Aut}(F_{p+1})$. We compu…

Anyone else constantly fighting Google Slides to save just ONE image? 😅 The screenshot struggle is real... or maybe even exporting to PowerPoint.
Check out this handy Chrome extension I found! 🙌
It adds a 'Download image' option right to your context menu (when you right-click on the image). So simple, so effective. ✨
Download full resolution JPGs, PNGs, etc directly.
I made a quick video showing how it works if you need this in your life:

A Novel Zero-Trust Identity Framework for Agentic AI: Decentralized Authentication and Fine-Grained Access Control
Traditional Identity and Access Management (IAM) systems, primarily designed for human users or static machine identities via protocols such as OAuth, OpenID Connect (OIDC), and SAML, prove fundamentally inadequate for the dynamic, interdependent, and often ephemeral nature of AI agents operating at scale within Multi Agent Systems (MAS), a computational system composed of multiple interacting intelligent agents that work collectively. This paper posits the imperative for a novel Agentic AI I…

I've just cleared out a bunch of hashtags I was following. I feel like they filled my timeline but didn't encourage me to reach out in friendship. And often the hashtag was the thing I scrolled past fast, thinking it was a bit ick.
(The hashtags you follow are in profile, then click on the 3 dots).
Let's see how a quieter Mastodon feels, and which hashtags I want to re-introduce...

Cycling question: trying out saddles, in the UK
UK cycling people, is there somewhere you'd go to sit on different saddles to test if they're comfortable? Is that a thing?
I've worked out that my (default came-with-the-bike) saddle isn't the right shape for me: it's giving me an achy tailbone, as well as I think being a bit too narrow for optimal sit-bone comfort.
For context, I'm an "occasional cyclist for pleasure and/or practical reasons", shall we say. No ambition to be super fast.
Looking around online, I think I want something more like the Rido R2 or one of the Selle ones, shaped to have air under the tailbone area. Or maybe even a noseless one like the Spongy Wonder, though I don't like the look of how the metal frame sticks out at the front of those.
What's the chances a shop would have more than one of those and a willingness to get them out for a test sit? Or, better still, is there a loan scheme anywhere, so you can actually "test drive" them for a bit? Or do people usually just buy and be willing to sell again?
I'm in Nottingham, and I know there are bike shops I could get to, but I'm not seeing "come in and try all these saddles, we'll help you to find the right one" kinds of messaging.
Could also potentially travel elsewhere at some point if it turns out there's some kind of "best place in the country for that question".
Advice welcome!

I've never written a novel or any other intensely-plotted work of fiction, but anyone who has read or watched it played a lot of stories can probably also recognize that some authors just aren't good at endings. They're great at setting things in motion, at keeping the twists and turns coming, at the soap opera style of drama. But they just don't have the craft necessary to tie things together into a satisfying conclusion. I imagine it's much harder than the process of getting things going out keeping them moving, since you both have to wind down all the various threads you've spun up and balance satisfaction with believability.
I just finished Girl Gone Viral by Arvin Ahmadi, and it has a bad ending. The beginning is fine, the middle has plenty of drama to keep you wanting to see what happens, but the ending is murky, unsatisfying, and manages neither veracity nor satisfaction (even discounting the biggest next step that might reasonably have been left there to make room for a sequel).
Given the other issues with the book, from poor politics, to inauthentic characters, to a techno-optimism that feels as bitter in this moment as it is far from the mark in its predictions, I can't recommended it, despite having read through to the end.
