“The #Sun on #Earth” - from #nuclear #fusion #technology

First of all, I would like to explain the #physical #basics of nuclear fusion. I will try to objectively work out the #advantages and #disadvantages of the new technology. Then, in a next step, I will present the #current #state of #practical #implementation of the technology and venture an #outlook into the #near/distant #future.

The Concept Of Indigenous GIS
--
Reading a paper (alturl.com/8wte5), they used the specific term ‘Indigenous GIS’ – and I found this intriguing!
As I read it, spatial data collection and analysis was done with a focus on how a tribe or social group might ‘see’ the data, including spatiotemporal....
I look forward to finding out more about what others are working on! – so PLEASE feel free to share any examples that you might have…

Watching Blobs of Paint Move to Chopin Is Oddly Soothing via Mental Floss [Shared]

The video, which was shared by Colossal, comes from French visual artist Thomas Blanchard. Set to Chopin’s Nocturne Op., 9 No. 2 (E Flat Major), it features iridescent blobs swirling through seas of glittery colors. The mesmerizing visuals are a perfect match for the soothing piano melody. If you need to turn off your brain for four and half minutes, this short film acts as the perfect mental refresher. 

Though it could easily be mistaken for high-quality CGI, Blanchard’s art is 100 percent practical. To make the trippy visuals in this video, he filmed paint, oil, and liquid soap interacting with each other. His work often zooms in on small scenes.

Overwhelm: The Survival Guide [Shared]

Feeling overwhelmed with work and personal tasks is one of the biggest problems that the people I work with are facing.
It turns out, our lives can be pretty overwhelming.

There’s so much to do, never enough time to do it, and who knows what we should be focusing on? We’re always behind, barely treading water. That’s our usual experience of life, it seems.

What can we do? It turns out, there are some powerful things we can practice with overwhelm, and there are some practical things we can do as well.

What follows is meant to be a kind of survival guide - not only how to survive your overwhelming life, but how to turn it into a life of joy and impact.

There are a lot of things below, which ironically can be overwhelming. Pick one, and try it.

@djb (Daniel J. Bernstein) tooted about a new blog post[1] he published. It's here:
blog.cr.yp.to/20250118-flight.

It's interesting. He's a #mathematician and software guy that in more recent years has been known mostly for his work in #cryptography, #theoretical and #practical. You're probably using his #Curve25519 every day in your #communications.

I'm not a mathematician (by a long shot), but it's written in a pretty accessible manner - it's not #formulae and #turgid academic #prose.

The central point he's getting at, by my possibly-mistaken understanding of it, is that current "common sense" about when attacks against pre-quantum cryptography like #RSA (and therefore when post-quantum cryptography becomes critical) are badly mistaken - based on bad assumptions about how attacks work, how they're implemented, and on badly #extrapolating from those bad assumptions using logic that doesn't actually represent the way attacks are developed and become practical.

TL;DR is something along the lines of "#quantum cryptographic attacks against RSA will be practical sooner than most people think, and you should be deploying quantum-resistant cryptography now, not later".

It's worth reading if you're at all interested in #crypto and #security stuff.

He also mentions a project he's involved in that has been discussed separately, transparent post-quantum tunnelling for unmodified #server and #client #software. Link in post.

[1] Written more like a conference presentation, FWIW.

#KamalaHarris on #Trump’s #economic agenda: “You see, for Donald Trump, our #economy works best if it works for those who own the big skyscrapers, not those who actually build them, not those who wire them, not those who mop the floor.”
Harris is presenting herself as a #pragmatist unbound by ideology.”We shouldn’t be constrained by ideology, & instead should seek #practical solutions to problems,”she says, offering herself as a #technocrat – #qualified & #capable.
