2020 marks the start of the quantum dot revolution.

Completely ignoring the fact that "photocatalytic generation of reactive oxygen species (ROS) from quantum dots (QDs) has been widely reported."
Results: It was found that whereas singlet oxygen (1O2) was not produced by photoexcited QDs, superoxide anion(O2− )and hydroxyl radicals(OH) were generated by QDs, especially in the presence of a physiological concentration of electron donating agent including NADH.
Using cell metabolic activity assays and various probes of ROS generation, the formation of ROS in cellular environments was demonstrated.
Conclusion: Illumination of QD-treated cells and bacteria with light did affect viability. The above results, together with those of assays in the presence of various scavengers of specific ROS, indicate that the formation of ROS by QDs mainly proceeded via electron transfer.
Some electrons are directly transferred to O2 to generate reactive oxygen species (ROS) in the ETC.
... As signaling molecules, ROS play an important role in cell proliferation, hypoxia adaptation and cell fate determination, but excessive ROS can cause irreversible cell damage and even cell death.
Electron transfer is a process by which an electron moves from one atom or molecule to another. It is a key concept in redox chemistry – the chemistry of reactions where one reaction partner loses electrons (oxidation) while the other gains electrons (reduction).
Ferric means the iron atom has lost three electrons to form Fe+3, and ferrous means the iron atom has lost two electrons to form Fe+2. ... For example, ferric would be Fe(III) indicating Fe+3, and ferrous would be Fe(II) indicating Fe+2.
Iron(III) oxide-hydroxide or ferric oxyhydroxide is the chemical compound of iron, oxygen, and hydrogen with formula FeO. The compound is often encountered as one of its hydrates, FeO·nH ₂O [Rust].
Similar behavior is exhibited by some iron compounds, such as the ferrites and the mineral magnetite, a crystalline form of the mixed iron(II,III) oxide Fe3O4 (although the atomic-scale mechanism, ferrimagnetism, is somewhat different).

So basically superparamagnetic piezoelectric crystalline nanoparticles dressed up as viruses do indeed cause oxidative stress related diseases.
Activated by light?

1. The death of Silicon Valley, a thread

How did Silicon Valley die? It was killed by the internet. I will explain.

Yesterday, my friend IRL asked me "Where are good old days when techies were


2. In the "good old days" Silicon Valley was about understanding technology. Silicon, to be precise. These were people who had to understand quantum mechanics, who had to build the near-miraculous devices that we now take for granted, and they had to work

3. Now, I love libertarians, and I share much of their political philosophy. But you have to be socially naive to believe that it has a chance in a real society. In those days, Silicon Valley was not a real society. It was populated by people who understood quantum mechanics

4. Then came the microcomputer revolution. It was created by people who understood how to build computers. One borderline case was Steve Jobs. People claimed that Jobs was surrounded by a "reality distortion field" - that's how good he was at understanding people, not things

5. Still, the heroes of Silicon Valley were the engineers. The people who knew how to build things. Steve Jobs, for all his understanding of people, also had quite a good understanding of technology. He had a libertarian vibe, and so did Silicon Valley
Humans inherently like the act of solidarity. We are social beings. We like to huddle up and be together.
They used this against us.
They convinced us that it was an act of solidarity to flatten the curve, to wear a mask for others, to take the vaccines for others,


and to reach #covidzero for others. They convinced us that this was for the greater good of society.
In reality, this couldn't be further away from the truth. They have divided us and broken the core structure of our society. They have dehumanized us with their masks.

They set us against each other into clans on opposite sides of a spectrum. They have turned us into aggressive beings fighting for our survival. Some of us fear harm from the virus, others fear harm from the vaccine, and yet others fear harm from the attack on our civilization.

We are all on a flight or fight mode. We are all operating under the influence of fear. We must collect ourselves and reflect on what has happened over the last year.
How is this for the greater good of society?

They used a tactical warfare strategy against us.
'Divide and conquer'.
We fell for it.
Now we must become aware of it and fight back.
We must reunite. We must find true solidarity to save our world. To free ourselves. To regain our autonomy.

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.

Legacy site *downloads* ~630 KB CSS per theme and writing direction.

6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices

https://t.co/qyl4Bt1i5x


PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.

735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.

The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
I’m torn on how to approach the idea of luck. I’m the first to admit that I am one of the luckiest people on the planet. To be born into a prosperous American family in 1960 with smart parents is to start life on third base. The odds against my very existence are astronomical.


I’ve always felt that the luckiest people I know had a talent for recognizing circumstances, not of their own making, that were conducive to a favorable outcome and their ability to quickly take advantage of them.

In other words, dumb luck was just that, it required no awareness on the person’s part, whereas “smart” luck involved awareness followed by action before the circumstances changed.

So, was I “lucky” to be born when I was—nothing I had any control over—and that I came of age just as huge databases and computers were advancing to the point where I could use those tools to write “What Works on Wall Street?” Absolutely.

Was I lucky to start my stock market investments near the peak of interest rates which allowed me to spend the majority of my adult life in a falling rate environment? Yup.
