PCI SIG exploring #optical interconnect

"Optical connections will be an important advancement for #PCIe architecture as they will allow for higher performance, lower power consumption, extended reach and reduced latency”

in reply to Yury

@shefys Signal propagation within circuit boards gets increasingly limited at higher frequencies due to capacitance. Optical is not for reach, but to get past this limitation.

in reply to Alan Sill

@AlanSill ah, I was thinking more in CXL context. Board level make sense - signal integrity is a real challenge for sure

Look, I get it. You always are connected to high-speed internet you've got all your streaming services, so the idea of losing different types of physical media may not mean much to you especially if you're not old like I am and you're used to having everything in physical media anyway. But take this for example:

SFMTA is proposing to reduce speed limits on a variety of streets, but SFMTA’s own data shows that only reducing speed limits — using signs — doesn’t decrease speeds.

SFMTA should reduce travel lanes by installing protected bike lanes.

in reply to Luke Bornheimer

"The most effective way to reduce vehicle speeds is to reduce travel lanes—by installing protected bike lanes, for example—and install physical infrastructure in the roadway to make it impossible to speed. Reducing speed limits with signs only does nothing.” sfstandard.com/2023/08/01/san-…

Slow boycott from my side if it EVER affects what I can and can't do
in reply to Brodie Robertson

I don't have much hope in the UK gov doing anything about it (though I've submitted an antitrust report anyway) so I'm banking on the EU being the ones to do something about it.


Is climate change the same as global warming? Not quite.

The warming of Earth — or global warming — is just one factor that makes up a range of changes that are happening to our planet, which is climate change.

And @nasa is studying all of it: climate.nasa.gov/

It’s not news that #beef production has an outsized environmental impact, but I appreciate this comparison to #coal:

"Relative to other food sources, beef is uniquely carbon-intensive. [cattle] produce seven times as many GHGs per calorie of meat as pigs do, and around 40% more than farmed prawns do. This makes beef a bigger outlier among foods than coal is among sources of electricity: burning coal generates just 14% more GHGs than burning oil, another common fuel.”

BioArtBot (bioartbot.org/) is a project for learning synthetic biology through creative expression.

A liquid handling robot "prints" the submitted drawing with microbes onto a petri dish. It places a few cells at each location, and over a few days these cells multiply until each "pixel" is actually a microbial colony (it uses strains of genetically modified E. coli).

The artistic value of the drawing I submitted is negligible, but my daughter is very happy with the result.

You know your backlog problem is real bad when enhanced edition of 20y old game you haven't had the time to start get their own bundles.

And you already have everything from previous steam sales (and maybe even bundles, but you can't remember).

#Tecnoafecciones Las empresas tecnológicas aplican políticas anti-reparación que obstruyen la capacidad de les usuaries para reparar o actualizar sus dispositivos por su cuenta.

⚒️ Reparar es un deseo genuino de contribuir a un entorno más sostenible y respetuoso con el ambiente.

in reply to Sursiendo

Reparar antes que reciclar como idea motora para la sustentabilidad pero también para fortalecer lazos territoriales y colaborativos. Seguro conocen está iniciativa pero, por las dudas, les dejo el enlace al club de reparadores que comparte esta preocupación por la obsolescencia programada en relación a los residuos tecnológicos (y otras hierbas).

"Christopher Nolan's #Oppenheimer explores the work of physicist J. Robert Oppenheimer & colleagues to create the atomic bomb.

Yet, the film fails to depict a key part of the story, using 2 female scientists as stand-ins for ALL of the women who contributed."

Hundreds of women were essential to the Manhattan Project, including Nobel Prize winning physicist Maria Goeppert Mayer. But they are largely absent in the #film.

Well, there’s a great way to ‘even the score’. I’d love to see #GretaGerwig direct a movie 🎥 about the “Girls of Atomic City” ☢️ 👉 exploreoakridge.com/who-were-t…
in reply to Sheril Kirshenbaum

It might be difficult to follow source material about Oppenheimer and tell a story with more women in it. Women were isolated. Men took credit for their work. Their involvement wasn't well documented.

I believe Nolan made an effort to depict them. It might have been a difficult job.

Here's an article from LLNL about Lilli Hornig. In the article she talks about being isolated from her peers.

Another background galaxy magnified by El Gordo is the bright arc in Box B: El Anzuelo, or The Fishhook. Light from this galaxy took 10.6 billion years to reach Earth! Webb peered through its thick curtain of dust to observe star formation and the assembly of galaxies up close.
#JamesWebb



Take a closer look at one of the magnified background galaxies. The long thin line in Box A is known as La Flaca, or the Thin One. Webb used its infrared sensitivity to spot a red giant star within, the first star of this type observed beyond 1 billion light-years from Earth.
#JamesWebb


Youths!

Webb observed galaxy cluster El Gordo, a cosmic teen that existed 6.2 billion years after the big bang. The most massive cluster of its era, it’s a perfect gravitational magnifying glass, bending & distorting light from distant objects behind it: go.nasa.gov/3YkoBCp

What could be better than experiments in space? Experiments on the Moon!

#NASAhistory

in reply to NASA

My favourite moon experiment was when the new camera refused to work, so some highly trained for anything moonwalker hit it with a hammer, a very expensive camera, a very expensive hammer, and the best part is: the camera started to work!

Only its tripod was never designed to absorb such a blow, and I recall the crystal clear video slowly tilting over, coming to rest pointing directly at the sun for a brief moment before going permanently dark.

Anyone else remember this?

in reply to NASA

Fun fact - my first paper of my PhD featured El Gordo! We were also the first to spot the galaxy-galaxy lensed partial ring, which you can see toward the right of the image. We used Herschel and ALMA observations, so we mostly saw the dust and gas rather than stars, but it's still a wonderful massive merging cluster.
