The Sound That Isn't There

August 20th, 2018 | Posted by pftq in Stories | #
Premise of a horror film I thought of while staying up too late. Tongue

Imagine every night you hear the loud humming of what you think are street sweepers driving by.  One night, you get tired of it and venture out into the streets to complain, except there's nothing there.  You run towards the sound, but it just keeps getting louder and louder, with nothing in sight for as far you can see.  The sound eventually starts moving away and goes quiet, like it does every night, and you go back home confused.

The next night, you run out again when you hear the sound, trying to get to the center of it before it goes away again.  This time, you keep running towards it as it tries to get away from you.  At first, you are barely able to keep up with the sound as it is moving away.  At some point, you realize the sound is suddenly getting louder and louder than it ever has before.  You get so caught up running towards the sound that you don't realize it has...[More]

Lossless Algorithms

August 12th, 2018 | Posted by pftq in Ideas | #
The following is a lossless algorithm I invented for generating support/resist in trading with no thresholds or parameters. On each price move, the price range traveled loses a point in score. The resulting score of any price range is its support/resist strength, which declines the more it is traveled across (zero being strongest and untraveled). Visually, the price line looks like an eraser scrubbing away ranges on the chart; ranges least scrubbed thin out to support/resist lines.  The reason I call it a "lossless" algorithm is because it doesn't estimate anything or use any seeded values/thresholds.  There are no knobs to tweak and no assumptions to take.  It is a perfect 1-to-1 map of where price moves most and least freely.  It is also extremely light both in computation and space because all you're doing is a single subtraction per datapoint and the max number of ranges to keep score of is one new range per datapoint.

Happiest Memory

July 15th, 2018 | Posted by pftq in Essays | #
The happiest memory in my life is not one I could ever share with anyone else.  Because it isn't a moment from within my real life but instead one from within a dream, a dream that occurred almost ten years ago.

In that dream, I spent my childhood alongside someone who would race me neck-to-neck as we leapt from rooftop to rooftop before eventually taking to the skies.  If one of us began to fall, we would catch each other and throw ourselves even higher than before, laughing as we did.  At the end of it all, we would sit atop an abandoned post that towered above the clouds and watch the sun set, not against the Earth, but against the sky itself, the ocean of clouds below reflecting the sun like a mirror.

The sensation of flying is something that would recur throughout my dreams.  It felt more natural to me than any movement on the ground.  It took effort instead not to float upward and drift away.  Usually in a dream, things are foggy, blurred, but...[More]

Perpetual Dreams

March 5th, 2018 | Posted by pftq in Stories | #
Another story I watched play out like a movie in my dream - ironically this one about a character dreaming...

A man lives his life through many lucid dreams.  In them, he is aware he is dreaming and can pick the setting or story he wants to live in.  One thing he can't control though is that the dreams seem to randomly end and reset.  While he keeps his memories from past dreams, no one else in the dream seems to remember.  Over time, he starts noticing a person who is always in the dream.  It starts off with them just passing each other by, walking in the same direction, or other small coincidences, but eventually they end up in the same scenes or situations as well.  She ends up being the only constant between each dream, and they share many adventures together.  However, whenever he tries to talk directly with her and figure out who she is, the dream cuts off.  It doesn't help that she also always forgets everything as well, so every...[More]

Data Does Not Equal Fact

January 24th, 2018 | Posted by pftq in Essays | #
"Data!=Fact: Inductive vs Deductive Reasoning"

Part of my frustration with all the focus on big data, statistics, quant, and numbers in general is that these are all forms of inductive reasoning.  Amidst all the hype around being more data driven, we seem to have to forgotten that inductive reasoning only provides an estimate of world.  It does not and cannot prove anything.  Evidence alone does not provide truth.  Data does not equal fact.

There are two main forms of reasoning:  inductive and deductive.  Inductive reasoning is the process of generalizing from a few observations to a general conclusion.  Deductive reasoning is the process of understanding what must be true and apply to something more specific given a premise or broader assumption.  The former is emphasizes correct observation while the latter emphasizes actual logical flow and reasoning, the how and why as opposed to just what it is you are seeing.

Reflections of 4D

January 8th, 2018 | Posted by pftq in Ideas | #
A nice read- https://gizmodo.com/two-experiments-show-fourth-spatial-dimension-effect-1821739488

Essentially if a 3D object has a 2D shadow, what if we looked for the 3D shadow of a 4D object? My thought is take it further - If our reflections are 2D, what about 3D reflections of a 4D object?

If you think about it, the answer to crossing all spacial dimensions is light.  We always perceive visually in two dimensions even though we live in three.  Just as a flat movie screen serves as the window into our 3D world, it is likely that our 3D world serves as a window to the 4th. This starts to relate also to where Virtual Reality and brain-interface technologies are going; I'd imagine that some combination of the two fields would be necessary for us to perceive more than just in 3D space.

The City of Eden

December 30th, 2017 | Posted by pftq in Ideas | #
Imagine a city where everyone could live in absolute luxury, indulge to their greatest desires, and never have to work or earn a living. It sounds wasteful and unsustainable, but if it actually existed, it might instead save the world.

This is because everyone who actually wants to live in comfort and pleasure would go there.  It would concentrate the bulk of the population in one place while leaving the rest of the world free and preserved.

The best part is that there would be no need to force people to go.  This is most people's idea of heaven on Earth.  This is what most people work all their lives to attain and retire to.  They would *want* to come here.

And for those...[More]

Steps to Biological Immortality

December 4th, 2017 | Posted by pftq in Ideas | #
I'm not going to hide it.  I want to live forever.  I don't think there's anything wrong with that or that it's "unnatural" or "unethical."  People often act offended on this topic.  "Why are you so greedy? Why so selfish?" But to them, I ask, why is it so bad to want to live? To who do I owe such a huge debt to that I am obligated to die?

One of my personal beliefs is that it is within our lifespans that we will figure out how to prolong our lives indefinitely - aka biological immortality.  Note this is different from actual immortality where you can't die at all; here we are just referring to dying of age.

At the same time, I don't believe there's such thing as a "natural death."  It is not necessary to die, and not all things do, even in nature.  Jellyfish and lobsters are both good examples, where their bodies never really deteriorate no matter how old they get.  Some will get technical and say that lobsters die of getting too large or their shell becoming too much to molt, but that's besides the point, which is that they don't actually lose vitality or youth over time like we do.  Their actual cells do not decay, and they don't become weaker or less able over time (in fact, they continuously get larger and stronger).  That to me is the goal and the definition of biological immortality.

Talking with an Ivy Leaguer on Wall Street

December 4th, 2017 | Posted by pftq in Stories | #
Another memoirs of sorts, this time reflecting the Ivy League alumni I've been meeting in NYC, both in the startup community and on Wall Street.  I've been spending more time in NYC instead of SF for a change of location (and people), but ironically, I'm running into sort of the opposite situation to that I had in my short story, Talking with an Engineer in Silicon Valley.  Whereas many I met in Silicon Valley lacked empathy, considerateness, and other traits but at least wanted them (even if superficially), the circles I'm getting into in NYC seem to simply accept that these traits don't genuinely exist and are always superficial.  Maybe it's just my luck that I'm just somehow always meeting the most 1-dimensional people, but the frustrating part is they always start off seeming normal in the beginning.  As with my other short story, the conversations below are nearly cut-paste from my personal experience, besides obvious name changes and other details to keep individuals anonymous and the story somewhat coherent.  For those easily offended, this obviously doesn't reflect every person from Ivy League or in Wall Street and is just a likely biased, limited subset of the real world from my own experiences.
