Hi . We need to talk about something.

While talking to a colleague about how I recently learned most people have never sat on a cow it came up that she has never sat on a horse. Like, not even once during childhood.

Another colleague admitted they also have never sat on a horse.

My hypothesis is that most people have at one point in their life sat on a horse.

Have you sat on a horse?

In case you missed it, new particle just dropped. The LHC has confirmed (and in ridiculous accuracy) the existence of a heavier version of the proton.
A proton is made of 3 quarks, up/up/down. This new particle is made of charm/charm/down, where the charm quark is basically the same as the up, just heavier.
So not groundbreaking like finding supersymmetric particles, but still cool. Further confirmation that the standard model of particle physics is reasonable.

LHCb Collaboration discovers new proton-like particle

The LHCb experiment at CERN’s Large Hadron Collider (LHC) has discovered a new particle consisting of two charm quarks and one down quark, a similar structure to the familiar proton, but with two heavy charm quarks replacing the two up quarks of the proton, thus quadrupling its mass. The discovery, presented at the ongoing Moriond conference, will help physicists better understand how the strong force binds protons, neutrons and other composite particles together. Quarks are fundamental building blocks of matter and come in six flavours: up, down, charm, strange, top and bottom. They usually combine in groups of twos and threes to form mesons and baryons, respectively. Unlike the stable proton, however, most of these mesons and baryons, which are collectively known as hadrons, are unstable and short-lived, making them a challenge to observe. Producing them requires smashing together high-energy particles in a machine such as the Large Hadron Collider (LHC). These unstable hadrons will quickly decay, but the more stable particles that are produced as a result of this decay can be detected and the properties of the original particle can therefore be deduced. Researchers have used this approach many times to find new hadrons, and the new particle just announced by the LHCb Collaboration brings the total number of hadrons discovered by LHC experiments up to 80. “This is the first new particle identified after the upgrades to the LHCb detector that were completed in 2023, and only the second time a baryon with two heavy quarks has been observed, the first having being observed by LHCb almost 10 years ago,” says LHCb Spokesperson Vincenzo Vagnoni. “The result will help theorists test models of quantum chromodynamics, the theory of the strong force that binds quarks into not only conventional baryons and mesons but also more exotic hadrons such as tetraquarks and pentaquarks.” In 2017, LHCb reported the discovery of a very similar particle, which consists of two charm quarks and one up quark. This up quark is the only difference between this particle and the new one, which has a down quark in its place. Despite the similarity, the new particle has a predicted lifetime that is up to six times shorter than its counterpart, due to complex quantum effects. This makes it even more challenging to observe. By analysing data from proton–proton collisions recorded by the LHCb detector during the third run of the LHC, the LHCb Collaboration observed the new baryon with a statistical significance of 7 sigma, well above the threshold of 5 sigma required to claim a discovery. “This major result is a fantastic example of how LHCb’s unique capabilities play a vital role in the success of the LHC,” says Mark Thomson, CERN Director-General. “It highlights how experimental upgrades at CERN directly lead to new discoveries, setting the stage for the transformative science we expect from the High-Luminosity LHC. These achievements are only possible thanks to the exceptional performance of CERN’s accelerator complex and the teams who make it all work and to the commitment of the scientists on the LHCb experiment.” Further information: LHCb presentation at Moriond is available here.

I used to not like JSON-LD. And then I got exposed to CBOR. And, since then, I ended up liking JSON-LD more than I did before.

j12t.social/@j12t/114581086678

...

I was looking for performant ways of storing JSON-LD data, so that it can be looked up, queried, etc.

CBOR might actually be a way of doing that.

...

For me that is an odd realization given me liking JSON-LD is a reaction to CBOR.

Does anyone know a museum or other institution that would be willing to take this large vintage railway wheel(?) press? It's marked "Chambersburg Engineering Co., No. 863", and a long time ago it was used to help maintain rail cars at the Port of San Francisco. Unfortunately it's going to the scrap yard this week because no museums we've tried are willing to come haul it away. boosts appreciated.

edit: Sorry folks, there was less time than I thought. It's already out the door this morning 😔

🚨🚨Judge Lamberth orders USAGM, by March 23, to bring back all 1,042 VOA employees, who have been on paid admin leave for a year and resume full broadcasting. The court also rules all the actions Kari Lake took to reduce US international broadcasting to a supposed “statutory minimum” are vacated.

Hey folks! Is there anyone here who has experience with resyncing subtitles and could recommend software to help me do that that runs on a Linux system?

Thanks 💜

Edit: it's not just about setting the speed factor and offset, I've done that dozens of times but the issue here is more complicated than that and what I need is a tool to help me analyze and fix it.

It's not perfect yet, but the foundation is there. I will publish the source code soon under AGPL.
