dfischer··on Faster Than Light in Our Model of Physics: Some Preliminary Thoughts
This reminds me of the fungi sub space system that was in Star Trek Discovery (season 2). Interesting.
dfischer··on Privacy is the most important concept of our time
The properties that which you describe are intrinsic to privacy as a feature in existence. To have privacy in a conversation in the physical world requires time, space, and experience.

These are very intrinsically-linked concepts.

dfischer··on A trip through the Graphics Pipeline (2011)
I am seeking a first principles approach to graphics. From poking a chip to manipulating bits and drawing pixels on the screen in the most raw form. Anyone know of any such books/tutorials? I need to study how the first terminals worked.

Assembly as the highest level abstraction. Anything equivalent to assembly anyway - a forth would be fine.

dfischer··on Privacy is the most important concept of our time
Privacy and the concept of property blur in the digital. This is interesting when taking the philosophy of natural laws and what a nation like USA is built upon (ideas of natural laws including property, defending life, and so on)

Encryption is the only way to have property in the digital universe, however the mechanics of property and cost are also entirely different. Once it exists it’s costless to reproduce in said form. However relying on encryption feels a little repugnant as it relies on transferring trust to a mathematical minority that truly understand it. And no encryption has ever gone unbroken with time. Should there even be a contrived concept of property in the digital universe?

Is there anywhere to learn more of these ideas or consequences in more detail? I’ve had various conversations of this but it would be nice to see a top down review of these ideas and actions in a modern light.

Greenarraychips are clockless: http://www.greenarraychips.com/home/products/index.html

Very interesting chips.

dfischer··on Memristor Breakthrough: First Single Device to Act Like a Neuron
Reminds me of ternary computers. I can’t think of the exact circuit type now but there exists one in three states that can make every other.

Also: https://en.wikipedia.org/wiki/Ternary_computer

These guys seem to be working on it in that way: https://knowm.org/
dfischer··on Fossil
Can anyone give a conceptual model breakdown of the data model of fossil vs git and trade offs? I’ve been quite interested in these types of structures. I need to play more with them.
dfischer··on Water on Mars: discovery of three buried lakes intrigues scientists
Woops:

> Some of them can withstand extremely cold temperatures down to 1 K (−458 °F; −272 °C) (close to absolute zero), while others can withstand extremely hot temperatures up to 420 K (300 °F; 150 °C)[36] for several minutes, pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space.[37] Tardigrades that live in harsh conditions undergo an annual process of cyclomorphosis, allowing for survival in sub-zero temperatures.

dfischer··on Some Physicists See Signs of Cosmic Strings from the Big Bang
What you described reminds me of these two things (visually):

1. 6-dimensional Calabi-Yau manifolds with Ricci flatness https://vimeo.com/81756249

2. Hopf vibrations: https://juliahub.com/docs/Porta/4MpHD/0.1.1/_packagesource/f...

dfischer··on Some Physicists See Signs of Cosmic Strings from the Big Bang
The amount of "observable universes" would be at what number given that each one is a string? How many potential strings from the initial moment? Seems... just mind boggling.
dfischer··on Some Physicists See Signs of Cosmic Strings from the Big Bang
How self-similar in thinking so, from the cosmos, to the roots, to the nerves, to the brain.
dfischer··on Some Physicists See Signs of Cosmic Strings from the Big Bang
I'm confused, "It is expected that at least one string per Hubble volume is formed." (10^31 cubic light years.) ... one string per an observable universe?

Or am I not thinking clearly?

dfischer··on Some Physicists See Signs of Cosmic Strings from the Big Bang
Interesting - feels related to Sungchul Ji's work: https://www.mdpi.com/2078-2489/8/1/24 Waves as the Symmetry Principle Underlying Cosmic, Cell, and Human Languages

Waves being a unifying concept of communication (language). It's quite interesting and rooted in strong fundamentals. Take a look if you're curious! There's more recent work published that you may find elsewhere other than that paper linked.

Purchasing behavior is literally what drives and directs the world today.
dfischer··on Using lasers to reduce drag in hypersonic weapons
Exactly. I think it may be up their sleeve, especially with their potential ability to tap into Tesla.
dfischer··on Social Cooling (2017)
> It performed data mining and data analysis on its audience. Based on results, communications would then be specifically targeted to key audience groups to modify behaviour in accordance with the goal of SCL's client. The company described itself as a "global election management agency".

Wow.

dfischer··on Mathwashing
Happy to see this being discussed. It's quite important and there's been some resistance in having these conversations.
dfischer··on Mathwashing
Under what principles and criteria do you standardize the review? What's the checklist?

If you are able to provide. Thanks.

dfischer··on Water on Mars: discovery of three buried lakes intrigues scientists
Tell that to the water bears: https://en.wikipedia.org/wiki/Tardigrade

Not only is their original habitat 420 K and 1 K (absolute zero) they’re described as “colony” species.

Quite interesting.

dfischer··on Using lasers to reduce drag in hypersonic weapons
10% is a huge reduction and would significantly add up to cost savings with the potential it compounds savings. I think it’s certainly a possibility. Might eventually be a focus for Space X.
dfischer··on US college enrollments are falling, except for graduate degrees
College has been a racket for a long time. There have existed huge issues on incentive structures and expectations. The hollywood dream of college life combined with the promise of adding value to an economy with a learned discipline.

The chasm that has grown between that fantasy and what the economy demands has been massive in the past few decades and the university system only increased it with political red tape.

I certainly agree that a layer that connects businesses with potential is the right shape. Something closer to the “apprentice” structure of before.

dfischer··on Amazon One – Palm recognition for Amazon Go
I certainly hope there’s alarms ringing in a few heads about this.
dfischer··on Judge temporarily blocks U.S. ban on TikTok downloads from U.S. app stores
What you’re describing is exactly what’s going on. Cambridge Analytics was the smoking gun. That unraveled what sophistication of technology is being used to mine the internet and control sentiment.
dfischer··on Judge temporarily blocks U.S. ban on TikTok downloads from U.S. app stores
It’s not a possibility that another company is doing it, it’s about the state actors involved in doing it and otherwise unknown parties. In the end it’s no specific company that is responsible as the aggregate whole of all data available and the mechanisms to algorithmically control content is the sophistication of manipulation going on today.
dfischer··on Judge temporarily blocks U.S. ban on TikTok downloads from U.S. app stores
Not the same at all given the sophistication of targeting allowed.

Yes, ads have always been this. But no, it’s never been like this.

All that data on the internet is being used to train algorithms to sway global sentiment. This emerges as bots, ads, interactions, content. It’s mind blowing.

dfischer··on Judge temporarily blocks U.S. ban on TikTok downloads from U.S. app stores
It’s more boomers AND TikTok. The whole enchilada. Wave after wave. That’s the scary part.
dfischer··on Judge temporarily blocks U.S. ban on TikTok downloads from U.S. app stores
I never said to focus on TikTok. I’m saying they aren’t mutually exclusive at all.

“ The Chinese government and the Chinese Communist Party exert control over many forms of media in China, including newspapers and the Internet. All Chinese media, including newspapers, periodicals, news agencies, TV stations, broadcasting, the movie industry and art performances, are categorized and managed as "mouthpieces" of the Communist Party, used to manipulate public opinion and exercise "mind control" on its citizens.[70] "Mind control" includes "indoctrination from kindergarten to college through officially compiled textbooks, as all teachers are categorized as 'educators of CCP' (The Chinese Communist Party)". According to Qinglian He, a former Chinese government propagandist and now a senior researcher at Human Rights in China, by exercising "mind control", the Chinese government has misled the Chinese population about the values of human rights and democracy, and also about the truth.[71] The Propaganda and Information Leading Group is generally responsible for censorship and control of information. The unit is also one of the largest in the CCP leadership organ.[72]”
