At least some rules can be bent...

...but not all of them are worth the time it takes.


Even if 99% of people are idiots, 1% is still plenty, and even if 99% of the things that the 1% does is idiotic, the remaining 1% is still amazing. That's the highest compliment and respect I can genuinely offer humanity. It's not exactly that people are stupid, it's something else, but there's definitely something weird, perhaps something wrong.


You can have something like soul, afterlife, rebirth and immortality from science. There are many ways. Maybe not particularly likely ways, but possible ways none the less. Perhaps you can even have a nearly rational reason not to kill yourself for a nihilist who values nothing, but the minimization of their own suffering. If quantum mechanics is true, there is a certain likelyhood that your essence will once again re-emerge as a continuum of your current consciousness (after more than astronomical timescales). It's only a question of how much suffering occurs between these occurrences and I would speculate that such suffering might be quite large and it would in fact be in your favor to live "forever" and strive for maximal control of your own experiences, even if your life was to be mostly mundane, uninteresting and to some extent pain. As long as you hold some power over your own destiny by staying alive as opposed to being dead (or "in between"), you might be better off. Not that you'd actually have any hope of control with these timescales, but one can always dream and at least you would maximize percentage of the time you are in control. Though, in general I'm in favor of persons right to end their life at will without regret should a need arise due to excessive pain or whatever. Anyway, in my ideal world, people would not die of old age or disease, but by their own hand and will after having lived a life they consider sufficient, some might perhaps say after having become bored of life. Whether that be 100 years or 100 million years.



"Necessitarianism is stronger than hard determinism, because even the hard determinist would grant that the causal chain constituting the world might have been different as a whole, even though each member of that series could not have been different, given its antecedent causes."

What exactly does a hard determinist believe then? Is hard determinism defined well enough to answer this question? That there exists a random element to the way the world came to be? Where does random come from? Even though I'm a necessetarian, I can still make estimates of the state of the world and what would constitute a better world for me and others and how to go about it as long as I acknowledge my finite understanding of what is necessary. I'm simply an agent of necessity even when making these estimates. My experience of choice is simply an illusion, but it's a wonderful feeling none the less and no one can take it away from me.

When I inform you that you have misunderstood my position you need to acknowledge this and attempt to correct yourself before proceeding to attack my position, otherwise you will simply waste everyones time by continuously engaging in irrelevant strawman arguments which have nothing to do with my true position.


I'm not saying (necessarily) that your argument has formal flaws, but there's no point in engaging with the argument itself before we get over the justification for its premises and as far as I'm concerned, we're nowhere near. We should properly acknowledge that if the premises are not sound then the potential formal validity of the argument implies nothing of the truth and is quite irrelevant.

If your god existed and it was his will then he would find a way to convince me. As this hasn't happened, I can only conclude that he either doesn't exist or wants to remain hidden, both irrelevant to me.

"Never waste your time trying to explain yourself to people who are committed to misunderstanding you."


Not only is all matter and energy just a vacuum fluctuation. Time and space are vacuum fluctuations as well. You lower a particle with energy E=mc^2 into a black hole and it loses all of its energy and with it both time and space cease to exist, assuming they had any independent existence to begin with.


What kind of person would I theoretically consider an ideal girlfriend (to the extent such a thing can make sense for me)?

A person who does not want to have children under any circumstances and has no (intrinsic) will or need to use intoxicants or be religious. The first appears totally essential, at least as far as I can see, there would be irreconcilable conflict otherwise. The only theoretical circumstance (if one wishes to be not entirely absolute) might be if I was ultra rich, like on the order of tens of millions of euros (and/or immortal). Only then the price would not be too high. The last two are something simpler. I experience them as a strong preference mainly for emotional reasons and I have supporting evidence of their value in the form of naturally increased feeling of trust, comfort, respect and other small things which seem to come with the package, but they may not be trivially essential if the conflicts are not large and may be shadowed by other things. Minor controlled conflicts may even foster valuable diversity under some circumstances and may lead to higher value for the sum of all things, that's why I'm never quite absolute even if it might sometimes appear so. The optimal balance may be very difficult to achieve though.

As I have very little tolerance for negative emotional expressions and irrational behavior, it would be quite essential for my company to naturally behave in a manner consistent with this. I also strongly prefer people who are pragmatic, empathic, intuitive on a wide spectrum, motivated, positive, patient, faithful, dedicated, trustworthy, unprejudiced and in general kind and goodwilled. I'm a strongly independent and introverted individual who needs certain distance, personal space and time. Therefore, in order for both of us to enjoy each others company, these qualities would probably need to be shared to fair extent.

I see my life as a personal expedition rather than a routine, achievement, competition, ladder or any kind of typical structure with stereotypical goals. I can value friends, their support, their entertainment value, their diversity, their intimacy, shared experiences, perhaps even a single special extended friendship with closer emotional ties to the opposite sex, but I find it unlikely I would ever see or want anyone to be much more than that and even then people for me are only for the good days, on bad days I prefer to stay alone and away from anyone or anything.


I strongly prefer people who are in tranquil and healthy equilibrium with their mind, body and emotions. People who consider their body a temple without totally excluding the value of small healthy or nearly healthy indulgence on occasion. People who have no will for permanent decorative modifications and who despise vanity for the most part. People who are not bound by any rigid ideas, opinions, goals or habits. People to whom most things are not a big deal. Perhaps one could even say, the eccentrics who are just a little bit above or at a distance from their culture, society, upbringing, social group and in general everything. Timeless people, perhaps healthy nihilists. Someone who is consciously their own individual and do not primarily compare themselves to others even though they are always willing to learn from others mistakes. Someone who is not afraid to fail. Someone who does not primarily work to please others or conform to any groups. Someone who considers an experience, whether emotional or otherwise, mostly as a case of diversity, a thing to learn, discover and enjoy for its own sake rather than some consumable or essential, least of all routine. Someone who at least in principle always strives to outdo oneself without considering themselves incomplete or defective.

In general most of these qualities are something I consider relevant to my emotional comfort, trust and respect, not to mention pragmatism. Some are more essential, some are less. I think many of these are a lot to hope for based on my experience of the human race as it presents itself in this time and place. This is one of the reasons why in general I have never found it very worthwhile to waste much of my time or effort for such aspects of life. I have never been particularly interested in having any relationships of the typical kind or particularly concerned at all, at most I would say I've had some interest in having some kind of comfortable diversity in my life. Some value can be found if a person can constructively challenge me on matters I've been not exposed to sufficiently even if they possess some uncomfortable qualities. This list is of course to large extent a list of my own personal character traits, but there are also some which are to lesser extent descriptive of me than I would perhaps hope them to be.

Then again, I'm not sure I could actually be bothered to have anything. Conscious creatures tend to be bothersome even when they're fine, and I'm bothersome too. Perhaps if the circumstances were close to perfection, but they never are, are they? What would be the point otherwise?

In some sense people are only entertainment to me and my altruism is only a manifestation of the valuation of diversity for my personal purposes. Never the less I consider it likely that as long as I live as if I have a chance to live forever this way of thinking could in principle make my behavior maximally good (by some hypothetical average standard based on shared values of conscious creatures as far as we can understand such) and perhaps in practice more moral than the behavior of many other people. As a scientist rejecting all absolute points of view, I am forced to believe anything is possible and therefore I am naturally bound to the maximally good path. I will strive to save the planet, its inhabitants and optimize their freedoms for myself for selfish reasons, but I will do all that none the less. If I find a mistake, I will strive to correct it. Whatever I might benefit from other people, they should symmetrically benefit from me as well. Like the veil of ignorance, I should rationally do onto other as I would have them do to me, one way or another. Sometimes I might even be kind for the sake of being random or perhaps one should say diverse.

"God" help if I ever lose my will to live, luckily doesn't seem very likely to happen though as I seem to have it in my blood to go on forever so to speak.

If you're hammer then all your problems look like nails.

What if things happen just because they're there? The world, as I see it, is exceedingly arbitrary.

I don't remember who said it, maybe nobody, I don't care, today I said it.

Raspberry Pi controlling a cheap digital frequency synthesizer. Some scaling needed for more interesting results.
Life is too short for anything reasonable, but I guess one might still figure out a way to have a little bit of fun by accident.


Never waste your time trying to explain yourself to people who are committed to misunderstanding you.



Anything I can't place a probability on I'm just going to ignore, because that simply means I don't know anything about it.

Relative phase stability of rtl_sdr sticks with common crystal doesn't seem too bad (100 MHz).

Your favourite friend is the one you can watch 9 consecutive episodes of Dexter with, without exchanging a single word. The foundation of your friendship is built on a mutual dislike of other people. Everyone else can only be tolerated on a bi-monthly basis for no longer than two consecutive hours at a time.

This one running now at 2.4 GHz sample clock. Should probably go with 3.2 GHz.
However, I need a nice OCXO for that, and I don't have one at the moment.
Also, I had some trouble with quality of my low voltage (1.8V/3.3V) supply (current demand is pretty high).
You often wonder why people can’t be more like you. You have mastered the art of minimal communication and as far as you’re concerned it’s working. You are awesome, hilarious and delightful, after coffee, over text, to people who actually care about what you have to say. Why can’t everyone else take a leaf?

Children irritate you for no reason what-so-ever. Their energy and spirit drains you. You often wonder if child-free restaurants are actually a thing and keep mentally reminding yourself to Google it.

You are convinced certain people exist for the sole purpose of pissing you off. Everyone has a purpose in life. This must be theirs.

We wouldn’t dislike most people, if people weren’t so ridiculously annoying. We have accepted that our every day life is going to be filled with interactions which we can’t be bothered with.

Sample clock 2.5 GHz now.
Spectrum analysis using rtl_sdr (this one goes up to 2.1 GHz) shows ~1.25 GHz peak on the computer to the left.
There's some crap above the Nyquist limit, nothing to worry about.

On the criticism of coherentism

>There is nothing within the definition of coherence which makes it impossible for two entirely different sets of beliefs to be internally coherent. Thus there might be several such sets. But if one supposes—in line with the principle of non-contradiction—that there can only be one complete set of truths, coherentism must provide a way to choose between these competing sets.

Yes and no. This only implies that we cannot know what is ultimately true (in absolute sense). This should be obvious in analogy to the halting problem in computability theory and Gödel's incompleteness theorems of mathematical logic (which again are all proven). The choice between two equally coherent beliefs is arbitrary. However, one theory is in practise always more coherent than others and even if they are on exactly equal footing, their current utility is equal and optimal so no problem exists.

Furthermore, the scale of required coherence expands as our experiences of the world keep growing so the coherence of our best theories converges towards the most coherent theory and theories incoherent with our experiences must be dropped out. The principle of non-contradiction applies, but coherentism has no need to provide a way to choose between two equally strong competing sets as the precise truth is unobtainable, yet coherentism allows an optimal way to approach this truth and provides a way to choose between unevenly matched theories.

The question as to why the Universe exists cannot be answered by "god" or "quantum fluctuations" because both of them are at most only parts of the Universe (which encapsulates everything). The explanation for the existence of the Universe must by nature be such that it leaves no references to any unexplained phenomena.

Everything worth doing is too expensive.

Hidden messages within the noise...


1) The LSB of the first line of pixels contains a code of random binary data.
2) This code can be used to calculate a cross-correlation value with the LSBs of the next lines of pixels.
3) The deviation of the xcorr value from the mean determines whether the line contained 1 or 0 (information is noisy with only approx. 15% of the bits transmitted).

This technique shares some similarities with the way the GPS transmits information with poor SNR.

pic = imread('/home/plahteen/code.png');
[a b c] = size(pic);

% extract the correlation code
code = double(mod(pic(1,1:b,1), 2)) - 0.5;

% calculate xcorr with LSB and code
for x=1:a-1
    co = double(mod(pic(1+x,1:b,1),2)) - 0.5;
    X(x) = dot(co, code);
end

% convert signal into binary
X = X>mean(double(X));

% decode
sprintf(char(bin2dec(vec2mat(sprintf('%d', double(X)), 7))))

It sucks in all my hopes and aspirations and all I'm left with is Hawking radiation of broken dreams.

Existence alone is not good enough, one should be able to do something worthwhile with it.
I didn't bring a whole lot back from Iceland, but at least some black sand.
"You're weird"
"Sorry..."
"No, that was a compliment"


"Of all sad words of tongue or pen, the saddest are these, It might have been."


Can you think of any random thoughts? Can you write a non-deterministic algorithm? Can you even imagine what it would mean? An effect without a cause? Clearly a very strange idea. Perhaps something beyond our imagination.

Deterministic systems are boring, one thing leads to another, you model your observations and you know everything there is to know about it. Non-deterministic on the other hand - a mystery, something weird. A painful reminder of the one thing we don't seem to grasp at all. Randomness with infinite period, something from out there.

I may dine with the devil, but the devil will never dine with me.

"I am a drifter, and as lonely as that can be, it is also remarkably freeing. I will never define myself in terms of anyone else. I will never feel the pressure of peers or the burden of parental expectation. I can view everyone as pieces of a whole, and focus on the whole, not the pieces. I have learned to observe, far better than most people observe. I am not blinded by the past or motivated by the future. I focus on the present because that is where I am destined to live."

"If you don't get everything you want, think of the things you don't get that you don't want."
"First, flood market with potatoes. Every single shop, fast food store, etc. has your potatoes. They're so cheap that no one can compete and ends up moving to other crops since they can't make a profit. Now, once your potato hegemony is established, slowly roll back potato supply. Enough to cause some rise in prices but not enough for panic. All of a sudden, stop potato supply. No one can supply enough to match your previous supply and the Great International Potato Inflationary Crisis occurs. World leaders clamor for you to resume your supply, and you laugh maniacally from your potato funded spaceship. Hold the world to ransom as supplies of chips, fries and crisps dwindle and die. Once sufficient panic has been created, get plastic surgery done and come back to Earth as the Potato Messiah, slowly bringing back potatoes to the world. The world is so grateful that they vote you World Leader. If they don't, cut off potato supply again.

I might face invasion - potato funded private military for my sovereign space state of Potatica would be used to fend off attacks and burn down competing potato farms on Earth. I mean I'm not saying you'd want to destroy people's lives and incomes, but they really shouldn't be growing potatoes.
Anyway, with near infinite potatoes, you have infinite ammo. With enough research and development we'd have potato bullets, potato armor, potato piercing rounds and potato cannonballs. Global military effort wouldn't stand a goddamn chance against the might of Potatica."


There exists no proof of anything real, and by nature of words (and fundamentally our existence) there never can. That's because the word proof only applies to ideas and reality isn't one. Math has proofs, physics does not. Your idea of reality is just a probabilistic model based on imperfect interpretations of your experiences.

Enough absurdity...

Nothing exists; even if something exists, nothing can be known about it; and even if something can be known about it, knowledge about it can't be communicated to others.

Just debated some idiots again and have to vent a little...


1) Nothing is ever proven in science. A proof is an operation of formal logic and is applicable mainly to mathematical truth only, which is basically simply consequence of axioms.

2) Science shows the validity of a theory by demonstrating it is a good model for a set of observations. It is not possible to literally prove any property of the reality. It is only possible to construct models of reality based on observations. The validity of these models is judged by their ability to make predictions.

3) Observation is any phenomenon which leaves some sort of relatively stable track of its existence. There can never be anything uncertain about an observation, only about the interpretation. There is a dependency between the repeatability of obsevations and reliability of the theory. That has historically been observed to be universally significant measure of the predictive power of the theory.

4) The mission of science is to model phenomenons. A model is a compact historically valid description of observations with significant demonstrations of predictive power (concerning then future). Scientific theory is the highest graduation point of this process. A theory is immediately invalid or at most only a limited approximation if it does not match some observation. (Though obviously this effect is sometimes just some fringe outlier. Never the less the exact interpretation of the sentence is still true, but it may often mean nothing more than the inability of the theory and experimenter to predict and observe the exact nature of chaotic thermal noise.)

5) Historically prevalent theories (like Newtons mechanics) have not been wrong, the word is not correct for the context, because they have only been appriximations which have later on been made more accurate by other theories (like Einsteins theory of relativity). Science does not assume theories to be exact models of the world, only good fits to the observations of their time with significant nonzero predictive power.

6) The purpose of peer review is to improve the reliability of generally accepted scientific models and increase the efficiency of progress by cutting out clearly invalid or highly unlikely meaningful material.

7) A phenomenon is not guilty of existence until shown otherwise.


Problem of induction
-------------------------
I'm of the opinion that this is nothing more than playing the game by the rules you have learned. If one day the rules no longer apply or you learn there are exceptions to the rules, you play by the new rules. Shouldn't this be trivial?

And as opposed to what? Not playing by those rules? Or playing by the rules someone else invented? Playing by random rules? Or not playing at all? Feel free, but expect anything.


Logical positivism
----------------------
I would say there is nothing wrong with the goal of logical positivism at all in its root. It was just taken too seriously. Too many saw the ultimate goal to be some sort of absolute mechanism for knowledge and nothing less would constitute to anything, but perhaps they failed to see the reason why such a road could only be approximated and approached never to be reached and perhaps to some extent the arbitrary nature of this endevour. The reason perhaps being finiteness of human experience. Perhaps the same fundamental principle which limits all courses of thought. Manifested by Gödel's incompleteness theorem and Turing's halting problem. We can't deal with absolutes or infinities. There is no finite self consistent doctrine and there can never be. After all, this was essentially proven. But why did they even expect such a thing? We can still approach infinitely even if we know we'll never reach it. We just need to decide to do so even if it is arbitrary and in some sense futile.

...and I still find it somewhat comforting that we also know that...

...any finite-state machine, if left completely to itself, will fall eventually into a perfectly periodic repetitive pattern. The duration of this repeating pattern cannot exceed the number of internal states of the machine...


Dualism, qualia and philosophical zombies - the hard problem of consciousness
------------------------------------------------------------------------------------------------
1) The claim is that qualia cannot be reduced to anything physical.
2) That is the claim, now demonstrate it, because I don't feel it.

What is it like to be a bat? Nagel argued that even if we knew everything there was to know from a third-person, scientific perspective about a bat's sonar system, we still wouldn't know what it is like to be a bat.

I don't see how this would point towards dualism. To me it simply means we are not the bat. The causal chain of thinking about pain is not the same as feeling the pain. And obviously "we" cannot have the same causal chain without becoming the bat.

"If my mental processes are determined wholly by the motions of atoms in my brain, I have no reason to suppose that my beliefs are true ... and hence I have no reason for supposing my brain to be composed of atoms."

Perhaps so, but nature doesn't care and neither do I. And in some ways, neither do you. Because you have no reason to suppose or to do anything at all. You just do. We keep living, and we keep playing the game, in the end because that's what we are, that's what we do and in some sense that's what we must do.

Causal interaction requires that dualism must explain how consciousness interacts with physical reality. Well they certainly don't explain it, but when someone said quantum mechanics they grabbed their last straw. I'd like to see their faces if quantum mechanics turned out to be deterministic, but though I think that'll turn out to be the case, even if that's not, we know things about the nature of quantum mechanics which seems to make it irrelevant. The statistical nature of quantum mechanics seems completely devoid of something I'd call mind and we understand and have tested that nature very well.


Somehow the strongest argument for the existence of some unknown aspect (which I still don't really believe) of the mind in is my mind the following scenario.

Let's say a machine capable of copying humans is made, and it is used to make a copy of you. (It is in fact impossible to copy exact quantum states, but let's say they are not meaningful or just simply ignore it.)

1) At the same time the original is destroyed. What do you experience? How do you feel (if anything) after this process has taken place?

2) Both the original and the copy are kept. What do you experience? Which "you" do "you" experience?

What does the experiencing? The universe? Is there a well defined you?

Some possibilities:

1.1) You die and experience nothing. A new consciousness is born (with your memories) and the universe goes about its merry business never knowing any better. But, what is death anyway?

1.2) You observe as if you'd been transported. But then is it actually "you" who's experiencing it or is it the universe somehow? One thing to consider is that the wavefunction of that which is essentially you has nonlocal properties according to quantum mechanics. Your wavefunction actually covers the whole universe and though it has peak existence here and now it is as objectively as can be, true, that you simultaneously exist everywhere and in fact everytime as well. You will "feel" what happens on the other side of the universe. Even locally your atoms are continuously tunneling from place to place and time to time and have no unique objective existence. You already are an information state of the universe. So quantum mechanics which was supposed to be the saviour of dualism has basically already beamed you up.

2.1) You keep your old body and experience nothing out of the ordinary. The copy is just a new consciousness born, but the universe can't tell the difference and perhaps neither can the copy, for the copy's point of view he was just you transported.

2.2) As you now essentially exist identically in two places at once you experience some sort of odd synthesis and duality of experience (but how?), perhaps what was you was some weird mechanism of the universe and something really odd occurs ...or not! According to quantum mechanics when atoms interact they entangle their states to some extent depending on the strength of this interaction. However, all atoms continuously interact (if only extremely weakly) with all other atoms. And they have a history of interaction as long as the lifetime of the universe already. You are already entangled with yourself, your friends, your surrounding and the rest of the universe. You have no independent existence, you never had. It's all just a matter of degrees. Perhaps whatever we could ever do could only be described as an unusually quick fast change in our state of affairs.
