#Covid lockdowns were an unusual gift. Watching my roses wilt, leathers crack, convictions shake, relationships dull and few loved ones taken away, I came to appreciate the essence of #chaos in a non-mathematical way. Art by Cindy Derby, from 'A Velocity of Being'
Riding the upstoppable arrow of #time, chaos can, and will take over everything – it's a question of when, not if. Spending 20+ hours for a whole year at home, I personally witnessed new order derive from, and decay back into chaos – yes, #entropy grows.
The silent master of #change, it lurks at the edge of all organisation, constantly tugging at equilibrium, ever ready to topple it into countless permutations of form, flavor and function. And through these, it shapes our shared, mortal destinies, at all #resolutions.

This week at SFI: "#Complexity and the Structure of #Music: Universal Features and Evolutionary Perspectives Across Cultures", an #interdisciplinary working group assembled to explore new frameworks for understanding music. Stay tuned for highlights!

"Every pitch class set is connected to every other pitch class set."

– @mbnUNT, co-organizer of this week's #musicology working group, presents on how to understand the #topology of #harmonic structures in music with #network diagrams (e.g. Pic 4 with #JSBach's BWV 66):
Once you represent a musical composition as a network, it is possible to examine the evolutionary dynamics of its harmonic content over time, as explained by @mbnUNT in his opening talk for this week's SFI #musicology working group.

(Ironically, this #Beethoven is #scalefree:)

Today's talk is with neuroscientist #KarlFriston of @ucl, who will offer a heuristic proof suggesting that life is an inevitable emergent property of any weakly mixing random dynamical system that possesses a #Markov blanket.

Tune in here at 12:15 PM MT:

...and because it's 2020 and nothing is ever simple, we are having technical issues with the stream. The talk is recorded and we will upload it across all of our platforms ASAP. Our apologies!
Spatial boundaries are statistical boundaries: #KarlFriston on #MarkovBlankets, the reciprocal interfacing between internal and external states.

Follow this thread for more highlights from the talk and stay tuned for the video link...

SECRET OF IMMORTALITY

The secret of physical #immortality is one of the deepest occult secrets of the Light forces that has never been revealed to anybody who has not reached a certain vibrational frequency, a certain inner purity and a certain degree of dedication to the Light. Image

I will now reveal to the surface population as much as it is wise to reveal.
 
Physical #immortality is reached through a certain conversion process, which is done by the right combination of three factors: Image
The #Archons and the rest of the #Cabal never understood this process in its entirety, but are searching for immortality nevertheless. They only have fragmentary understanding of the process which they stole from #MemphisMisraim masonic lodges.

Just had a wild idea, so bear with me:
Imagine an #opensource #cryptocrowdfunding model for software products, the kind you buy from @awscloud @Azure @GCPcloud and also the smaller players like @digitalocean and @Rackspace m, where there are no hardware licenses. 1/
You don’t even have to run the software or have access to the hardware running it in this model. Instead of #softwarelicensing, #developers set #crypto #staking thresholds which act as #digitalaccesscontroltokens; #stake x of whichever #Crypto, or y of another, with a discount 2/
when using the project’s #sidechain. So you get staking setup, and essentially get #APIkeys which allow you to join the network in r/w mode. Or you could say to heck with all that, I just want to pay someone. You can pay the network directly to do the work the software does. 3/

"You don't see radio changing gradually and suddenly become radar. #Darwin's theory doesn't work for #technology, and we have to make a new observation."

Unlike the two-parent #inheritance typical to (but not ubiquitous among) #complex organisms, #technology inherits features from n parents - a "vast ancestral #network" more like horizontal gene transfer networks in #bacteria.

"Life did not invent #DNA."

Experimental support for the #hotsprings hypothesis for life's origin: David Deamer of @ucsc on nucleic acid polymerization in the wet-dry cycling of Darwin's "warm little pond," powered by #geothermal. Lab results confirmed in #hydrothermal pools.
From "boring statistical partitioning" in the fission of early protocells to the complex #homeostasis-driven #mitosis of the cells we know - Doron Lancet of @WeizmannInstSci on the gradient between closure of #autocatalysis #networks to complex regulatory mechanisms of #biology.
"Life is an integrated nested network of dynamic #kinetic cycles."

So I wanted to encrypt some files. Thought about using 7z+password. Stackexchange folks said "Didn't review it but it should be fine. You can browse the code yourself". So I did. After a few mins I noticed they use 8byte "random" IV. Yes, half of IV is zeroes. But it gets worse.
Aside from the fact that 7z XORs plaintext with zeroes, I was curious about the "RandomGenerator" which generates IV. That's when I vomited. The first comments say "This is not very good random number generator. Please use it only for salt." It is not used only for salt.
Yes, it uses PID and time(null) as seed. Yes, this is 7zip's random generation code running on your computers in 2019. More "cursed" code below. #7zip #encryption #facepalm #randomness #entropy #RNG #crypto #cryptofail
