If you pick two points at random inside a regular dodecahedron and draw the line that contains them, that line can intersect three different kinds of pairs of faces, separated by angles of:
π, arcos(–1/√5), or arcos(1/√5)
The probabilities of these three events are:
1/4, (1+φ)/4, and (2–φ)/4
where φ is the golden ratio!
There is a general formula that applies to a d-dimensional regular polytope with f faces, for a single pair of faces separated by an angle θ:
P(d,f,θ) = 2d (cos(θ)–1)^2 / [(d+1) f^2]
That gives probabilities of:
1/24, (1+φ)/120, and (2–φ)/120
for the three possible angles, and there are:
6, 30 and 30
such pairs in total.
I give a proof of the general formula here:

We're happy to announce three projects will be funded to contribute to the TALER secure electronic payment system based on open standards, free software, and advanced cryptography.
The three projects are:
Libre Payments in Ruby, a GNU Taler Integration for ethical trade.
Taler in Liberapay, an implementation of Taler as payment provider in Liberapay.
And Taler OpenAPI specification, a JSON/YAML OpenAPI for key GNU Taler API's.

Hello dear @lutindiscret
Thank you for informing us about lokavaluto.fr/ !
We suggest that you join us on TALER ICH and post your question there! We are building a vibrant community around GNU Taler, bringing together consortium members, grantees, allies, and other stakeholders interested in our work. Sharing and responding to important questions in the forum will also help future visitors who may have similar queries ich.taler.net/ 😀

Not a dumb question at all. Yes, a merchant needs to be able to accept payments with Taler. Right now, there exist a couple of integrations with existing online shop systems such as Pretix, Drupal and WooCommerce, more to come, hopefully (if you have an idea, apply to our open calls! See nlnet.nl/taler/).
For physical shops, merchants can use our PoS software for Android tablets. We expect (well, hope) that at some point vendors of commercial PoS terminals will integrate the protocol.
In both (online and physical) cases, the merchant also needs to either run the GNU Taler merchant backend server themselve, or become a tenant at a service provider that runs that backend for multiple merchants.
F.e. POT (pot.ch), a cooperative of local food suppliers around Zurich, 🇨🇭, is doing the former: it runs a merchant instance for all members in the cooperative, and Swiss customers will soon be able to pay in Swiss Franc via GNU Taler, with taler-ops.ch as payment service provider.

The Evidence That AI Is Destroying Jobs For Young People Just Got Stronger
In a new paper, several Stanford economists studied payroll data from the private company ADP, which covers millions of workers, through mid-2025. They found that young workers aged 22–25 in “highly AI-exposed” jobs, such as software developers and customer service agents, experienced a 13 percent decline in employment since the advent of ChatGPT. Notably, the economists found that older workers and less-exposed jobs, such as home health aides, saw steady or rising employment. “There’s a clear, evident change when you specifically look at young workers who are highly exposed to AI,” Stanford economist Erik Brynjolfsson, who wrote the paper with Bharat Chandar and Ruyu Chen, told the Wall Street Journal.In five months, the question of “Is AI reducing work for young Americans?” has its fourth answer: from possibly, to definitely, to almost certainly no, to plausibly yes. You might find this back-and-forth annoying. I think it’s fantastic. This is a model for what I want from public commentary on social and economic trends: Smart, quantitatively rich, and good-faith debate of issues of seismic consequence to American society.

As big techs são inimigas de classe. A estratégia de comunicação dos comunistas precisa ir além delas
Entender as big techs como inimigas de classe e suas mídias sociais como o terreno adversário nos impõe a tarefa de enfraquecer esse inimigo, de acumular forças em nosso terreno, e isso passa por direcionar as pessoas para fora dessas plataformas, o que está longe de ser uma tarefa fácil. É preciso resistir à tentação de afirmar que sites tradicionais, como o portal do partido ou o Vermelho sejam o bastante. A dinâmica da internet nos últimos vinte anos é dos usuários se restringirem cada vez mais às plataformas sociais, onde é mais difícil competir com as plataformas imperialistas, porque o valor delas depende principalmente do conjunto de seus usuários. Esse empecilho torna a proposta de criar uma “rede social de esquerda” quase um devaneio quixotesco. As pessoas não participam de plataformas sociais monotemáticas e podemos ver um exemplo prático com o relativo fracasso do ICL em lançar uma rede social recentemente.

This is a Democratic campaign strategy letter from February 2022 with research about American's attitudes towards covid. It says Americans are tired of dealing with the pandemic. It recommends minimizing covid and emphasizing the personal responsibility of vaccines. A “we have the tools” and “covid is like the flu” messaging strategy.
The image shows a man standing in a room with large windows, holding a large blank white board in front of him. He is wearing a dark suit, white shirt, and a bright yellow tie. Behind him, there are several flags, including the American flag, and a window with a view of greenery outside. The room appears to be an office or a formal setting, with a dark leather chair visible in the foreground. The man's expression is neutral, and he is looking slightly to his left. The blank white board he is holding is the central focus of the image, obscuring his face.

Ukraine's Defense Intelligence Prymary unit carried out drone strikes on a Russian airbase in Hvardiiske, near Simferopol in Russian-occupied Ukrainian Crimea, successfully hitting Russian Mi-8 helicopters.
The estimated value of the disabled helicopters ranges from 20 to 30 million dollars.
A Russian tugboat, likely the BUK-2190, was also attacked in Sevastopol Bay.

I was saying "God-all-ming". I pointed at the map. He said "Oh, you mean 'Got-ul-ming'. He sold me a ticket only after I was able to demonstrate that I got the pronunciation right.

I have a 3D printing confession to make.
I ordered my first 3D printer kit in 2015, assembled it in 2016, and yesterday I ordered my fourth 3D printer.
I haven't printed huge amounts; mostly I've used CAD to design tricky parts with small details, and then struggled to print them.
In all that time, I've never tried glue stick for bed adhesion.
Yesterday, I relented and gave Elmer's purple glue stick a try.
It works!
Just make sure to have none of the spray be sucked in by a fan or get onto the belts, pullies etc. They don't like that. 🤭
At the end of the day it probably doesn't matter whether you're using a glue stick or adhesion spray. I just found the first to be easier and quicker to use.

Hey #NFS / #FreeBSD / #NFS4 experts, I have a weird one.
My file server exports the path:
/common/media to various devices in my house.
All read-only.
There are sub-dirs under it, books, movies, tunes, and cams, plus some junk I have yet to sort. I should note that some of it is owned by nobody:nogroup, some is nuintari:nuintari (for some reason I should clean it up), and the rest is root:wheel, except.....
The clients can see all of this, EXCEPT for cams.
The exports looks like this:
V4: /
/common/media -ro -maproot=root -network 172.16.17.0 -mask 255.255.255.224
There are tons of files under cams, its a syncthing backup for our cellphone's cameras.
The only difference is that the the files in cams come from inside a jail, managed by bastille, where /common/media/cams is mounted inside the jail via nullfs. But even files I create directly in the root filesystem on the server itself, outside the jail are not visible to the clients. This directory and everything under it are all owned by syncthing:syncthing FYI.
Yet every other file under this exact same NFS mount works fine.
Anyone have any ideas? I've been ignoring this for a few weeks now hoping inspiration would hit me. But I got nothing.
