Lightweight Cryptography | CSRC | CSRC
There are several emerging areas (e.g. sensor networks, healthcare, distributed control systems, the Internet of Things, cyber physical systems) in which highly-constrained devices are interconnected, typically communicating wirelessly with one another, and working in concert to accomplish some task. Because the majority of current cryptographic algorithms were designed for desktop/server environments, many of these algorithms do not fit into constrained devices.
The padlock in the browser is pretty safe and very difficult for anyone to snoop on what is being transmitted. Although for low power IoT devices, such resource-intensive cryptography is not possible. This competition resulted in several unique ways for devices to cryptographically encrypt the data they are sending.
An actual, real-world use for robot dogs
At a pumped storage plant in western Austria, a company called Energy Robotics is testing robot dogs for inspection. All the fancy Boston Dynamics publicity ...
We all have seen the Boston Dynamics dogs - but I always wondered about its real world use - what can't be done with cameras and automated systems? This video by Tom Scott presents its real world use apart from studying volcanoes and its in a totally human-less dam.
Ethiopia's war one year on: How to end the suffering
Tigray's rebel forces currently have the upper hand in the war that erupted a year ago in northern Ethiopia. Prime Minister Abiy Ahmed, who fell out with the governing party of Tigray over his political reforms, has declared a nationwide state of emergency - it is fear and uncertainty that now rule.
There has been a whole war going on in Ethiopia for a year and I was totally not aware about it. Really sad about what the media (even social networks) cover for the most part. If something is repetitive and bad it isn’t important for people to know - ridiculous!
Elements may have been forged on Earth, as well as in space - Physics World
Creating elements lighter than iron might not require the extreme conditions found inside very massive stars. According to a group of physicists in Japan and Canada, it is possible that oxygen, nitrogen and all other elements with atomic numbers up to 25 have also been produced inside the Earth.
> Creating elements lighter than iron might not require the extreme conditions found inside very massive stars. According to a group of physicists in Japan and Canada, it is possible that oxygen, nitrogen and all other elements with atomic numbers up to 25 have also been produced inside the Earth. Their eye-catching claim relies on the idea that fusion reactions occur in the Earth’s lower mantle, where they are catalyzed by neutrinos and excited electrons.
A song that I really enjoyed listening to. Spotify
Hiding Images in Plain Sight: The Physics Of Magic Windows
I recently made a physical object that defies all intuition. It's a square of acrylic, smooth on both sides, totally transparent. A tiny window. But it has the magic property that if you shine a flashlight on it, it forms an image: And if you take it out in the sun, it produces this 3D hologram: This post describes the math that went into making the object, and how you can create your own.
Found it from a list of submissions to 3B1B’s SoME1. It’s just pure magic-like and math too cool. Although I still wonder about how the hologram thing happened. A must read.
A really interesting website. Powered by solar energy and Raspberry Pi. Completely static and the images also optimized in a very unique way. Also gives such a unique perspective on why everything does not need to be always 99.9999% of the time working perfectly. For long term sustainability it provides a strong argument imo on not expecting everything to be always on.
Contract for Sale of Soul
SALE OF SOUL AGREEMENT This Sale of Soul Agreement (hereafter "Agreement") is effective as of the date upon which the party selling their soul (hereafter "Seller") signs the contract and returns it to the party receiving the soul (hereafter "Buyer") in either electronic or physical format. This agreement is entered
There are people who do not believe in the soul. It's just funny seeing them still disagree to sign such a contract.

Damn, Intel! // Intel 12th gen - pretty competitive (at least when there is enough power to chew through)
