What would happen if you could take a piece of matter from a neutron star and keep heating it up under pressure? You can pump more and more energy into it - but according to Rolf Hagedorn's calculations back in 1964, its temperature will never go above 1.2 trillion kelvin! Past that point, all the energy goes into creating more and more new kinds of particles and antiparticles.
You see, the matter in a neutron stars is not just neutrons. It's also made of protons and other kinds of particles, called hadrons (not hardons). Only the lightest of these are common at low temperatures. But if you could heat the matter in a neutron star, so the neutrons start colliding with each other more energetically, there would get to be enough energy that more and more different kinds of massive particles get created in these collisions.
At least that was his theory. Now we know that all these particles are made of quarks and gluons, and when the temperature gets high enough these particles smack into each other so hard that they just *break*, creating a quark-gluon plasma.
But his idea of a maximum temperature was a good one. Whenever the number of energy levels of a system grows exponentially or faster with temperature, it will have a maximum temperature! And this is called the 'Hagedorn temperature'.
The simplest example is the 'primon gas', a theoretical gas where there's one kind of particle for each prime number, and the energy of the prime p is log(p). The partition function of this gas is the Riemann zeta function. 🤓 As you heat this gas, you approach the pole at z = 1, and you create a shitload of prime numbers.... in theory.
I'm writing about this stuff for my book on entropy.

Your attention please:
Maybe you've never heard about it but since 2020, the Next Generation Internet programs, a sub-branch of the European Commission’s Horizon Europe program, have been cascading funding (via @nlnet calls) open source software in Europe. The massive fundings have enabled a great deal of free software development in recent years, and all without too many constraints (with too few transparency and monitoring, though… which urgently needs to be improved). Unfortunately, these NGI programs seem to have been withdrawn from the next round of Horizon Europe fundings to give priority to AI bullshit.
As a result, we’ve been invited to contact the National Contact Points, Horizon Europe’s national representatives, to express our concern and the importance of maintaining public funding for free software. With this in mind, we wrote an open letter at Petites Singularités and thought it would make sense to fork it out with Hackstub and ARN in Strasbourg for the French NCP to get other French-speaking free software orgas to sign. I’m thinking in particular of the software that has benefited from this funding, such as Yunohost, but also of the Kittens that use this same software.
We can also announce that this topic will be part of the central theme of the next #OFFDEM in Brussels, on the first weekend of February 2025. There's not yet an exact title, but we’ll be discussing financing and community structuring for free software over the next few years.
If you want to sign the french-speaking version of this letter, there's a pad for it: pad.public.cat/lettre-NCP-NGI

The true cost of not prioritizing accessibility: Avoid risk and maximize product ROI
"...if a bug is found in the requirements-gathering phase, the cost could be $100. If the product owner doesn’t find that bug until the QA testing phase, then the cost could be $1,500. If it’s not found until production, the cost could be $10,000."

Stepping down as GNOME Internships organizer
For the past nine years, I’ve been actively involved in our internship initiatives with Google Summer of Code and Outreachy. As an alumnus of these programs, I firmly believe they are great ways to onboard new contributors to GNOME and help students start a career in open-source software.
However, as my work responsibilities have grown and I’ve started some personal (non-software) projects, I’ve found myself with less time and energy for this type of contribution.
I’ve been discussing this with key people over the past year, and I plan to stay around to hand over responsibilities to other members of the Internship Committee. I will continue helping manage things for 2024, but I won’t be directly involved beyond that.
If you’re interested in helping with these activities, please reach out to the GNOME Internship Committee.

Went down a rabbit hole reading up on adventure game history and half way through I’m thinking “nearly every genre-defining game has its own engine”. No one in gaming says “oh, why’d you reinvent a game engine for your game?” It’s clear why… you’re creating something unique and you need an engine tuned to its needs. And you want to be able to use the engine for other, similar, games.
Which made me think: Kitten is the game engine for the Small Web.

And I want to say I'm loving the state of #GNOME's app ecosystem. Lots of apps, most of them really nice, many of them incredibly polished and well designed. The vision of small applications that do one thing and do it great was never so close.
All my love for the developers of these and many other great applications out there, and also for the GNOME community, for creating the ground for such an ecosystem to grow.
In einer Welt, in der Smartwatches und Fitness-Tracker immer beliebter werden, wird eine zentrale Frage immer drängender: Wie sicher sind unsere Daten? Die meisten dieser Geräte sind auf proprietäre Apps angewiesen, die häufig persönliche Informationen, wie Gesundheitsdaten, an externe Server übermitteln.
