placebo··on A World Run with Code
Not directly related to the article, but going through the comments, I felt the vibes and wanted to express my theory about what it is that irritates many of the commenters here

The highest pursuit is the search for truth. This includes the challenging act of discarding things that we'd really like to be true, but are false. The success of science can be attributed to extreme selfless intellectual honesty. The more ego gets in the way, the more the truth is compromised. Intelligence can be used in service of finding truth or in feeding our delusions. My view on the distinctions made here between genius and madness are that they correspond to the degree in which intelligence serves truth or delusions. Therefore I'd expect the most outstanding scientists in history were also very humble (perhaps someone with better knowledge on the personality of great scientists can shed more light on this).

And to keep things consistent - I might be wrong and thus welcome challenges to this theory :)

placebo··on Why have so many physicists shrugged off the paradoxes of quantum mechanics?
> All human models of reality are flawed.

Definitely. I wholeheartedly subscribe to this view (https://en.wikipedia.org/wiki/All_models_are_wrong). The thinking mind will always be confined to models. The way I see it, the questions posed here are an expected wall one will eventually hit when the mind attempts to explain something that is fundamentally inexplicable - i.e the nature of existence.

My current intuition is that the hard philosophical questions posed by probing deep into what matter essentially is are deeply linked to the hard problem of consciousness.

I'll make an even bolder claim, which is that both of these questions arise from a misunderstanding of what consciousness actually is and that no less than a Copernican revolution in understanding its role is what's needed to put them to rest.

Of course, that won't be the end of physics, as the mystery is endless - but it might be the start of a deeper humility and appreciation of that mystery.

placebo··on Mathematics and Computation [pdf]
My exact sentiments. This isn't adding anything of value as an HN comment but I just wanted to share my appreciation of this book as well as my frustration that there are only 24 hours in a day...
placebo··on You Are Not Google (2017)
> it implies that it's all zero sum and there's nothing that's ever unconditionally better or worse than anything else

Not necessarily - to start with, a good trade-off is unconditionally better than a bad trade-off.

Also, progress brings with it increasing complexity. Recognizing the best path includes assessing many more parameters and is far more difficult than deciding whether to use a hammer or a rock to nail things. The puzzling nature of many people to over-complicate things instead of simplifying them makes the challenge even more difficult.

By the way, the closest thing I've ever found to a silver bullet in software development (and basically any endeavor) is "Keep it simple". While this is a cliche already, it is still too often overlooked. I think this is because it isn't related to the ability to be a master at manipulating code and logic, but the ability to focus on what's really important - to know how to discard the trendy for the practical, the adventurous methods to the focused and solid - basically passionately applying occam's razor on every abstraction layer. If this was more common, I think articles like "You are not Google" would be less common.

placebo··on Procrastination Has Nothing to Do with Self-Control
This whole thing about character flaws and self control reminded me of the following passage from Raymond Smullyan's "This Book Needs No Title":

I know one woman who smokes. She says: “It’s not that I have to smoke; I choose to. I could easily give it up any time I wish to, but I see no reason why I should. But I can assure you, I could if I wanted to.” Her husband says to her: “That's only a rationalization! You couldn’t give up smoking even if you wanted to. You are not strong enough to give it up; you have to smoke. So to make yourself feel better, and to avoid having to confess your own weakness of character, you fool yourself into believing that you choose to. But it’s only a rationalization!” I know another woman who smokes. She says: “It’s not that I want to smoke; I can’t help myself! I have tried several times giving it up, but I have failed! I'm afraid I just don’t have a very strong character. I would love to stop, but I simply can’t.” Her husband says to her: “That's only a rationalization! You certainly could stop immediately, if you really wanted to. No, you choose to smoke (after all, nobody is making you) and you feel ashamed and guilty for doing that which you know to be harmful. So to avoid any moral responsibility for your acts, you fool yourself into believing that you ‘can’t help it. But this is only a rationalization.” My only question about all this is: “Why are people so incredibly stupid?”

Pity he didn't expand on the last line, but I think deep introspection is required to understand what is really under our control

placebo··on It’s not about how many countries you have been to
Thanks for the link - I loved its accuracy and humour :) In many ways, I think it's possible to apply some of the good answers here to any "how many X have you been to" question.
placebo··on Poor-quality relationships linked to greater distress than too few relationships
This assumes the only way to persuade someone to change their minds is via unpleasant confrontation. In my experience this is very rarely needed. You're right that a lot of confidence is required though, but it is the type that is rooted in truth and humility (rather than confidence from convincing yourself how great you are).
placebo··on Why Be Honest If Honesty Doesn’t Pay (1990)
My take on it is that it just boils down to what your highest insights are about what is important in life. If you believe that the maximum we can hope for is just to be sophisticated animals, acting in a sophisticated jungle, aiming for more sophisticated forms of animal goals (gain the most power, impregnate the most females etc.) then through that particular filter, indeed honesty doesn't necessarily pay off and dishonesty can be just another good tool in the toolbox to achieve king of the pack status.

There are however those who aren't content with just being sophisticated animals. They want to to dive into the depths that no animal can reach, and that requires self-honesty, and uncompromising honesty at that. And there is no way you can truly be honest with yourself while being dishonest with others, for reasons which become evident once you walk this path. This path (if traveled to its full extent) pays way more dividends than any benefit gained from prizes given by the sophisticated jungle. So, whether honesty pays or not, really depends on what sort of existence you seek.

placebo··on Machine learning leads mathematicians to unsolvable problem
"In the latest paper, Yehudayoff and his collaborators define learnability as the ability to make predictions about a large data set by sampling a small number of data points. The link with Cantor’s problem is that there are infinitely many ways of choosing the smaller set, but the size of that infinity is unknown."

Reading this got me wondering about more philosophical aspects, such as the relation of this conclusion to to the process of human learning and prediction (which obviously works) and whether it's somehow tied in some way to the problem of induction. Could be nonsense, but I'll be putting some more thought into the meaning of this

placebo··on OnSen UI – Develop HTML5 hybrid and mobile web apps
More software development options give you more freedom to choose a path that gives the best solution to the problem you're trying to solve. That is "beautiful" for me. Software development in the real world is a game of trade-offs. You have time-to-market and various other business considerations to take into account. Many times, choosing the "best" technological solution will harm your business. What is best and beautiful depends on the wider context.
placebo··on Hacker's guide to Neural Networks (2012)
You might be confusing "smart" with "knowledgeable". There's no way to be smart about concepts you haven't yet learned. And the ELI5 idea is cool - just need to find a business model :)

placebo··on Ask HN: Did you delete your Facebook account in 2018?
I opened an account long ago - I think around the same year Facebook started. I never really understood the appeal in the first place, but I keep the account around for the odd chance someone from the past might want to get in touch. I'm not exactly Facebook's dream user. Other than confirm friend requests from people I know once every few months, I have no use for it.
placebo··on Photons, Quasars and the Possibility of Free Will
I think a better way out of the trap of the free will vs. determinism question is to really dive not into the question of whether or not we have free will, but of who exactly is asking the question. What exactly is this me that's supposed to have this thing we call free will.

The first change in my perception of this question was many years ago when I read Raymond Smullyan's piece "Is God A Taoist" - I think it's definitely still worth read:

http://www.mit.edu/people/dpolicar/writing/prose/text/godTao...

placebo··on Photons, Quasars and the Possibility of Free Will
Consider the possibility that whether the future is predetermined or not has nothing to do with free will.

The persistence of the notion of free will seems to be an attempt to reconcile a feeling of what seems to be a very real, conscious and subjective "me in here" vs, what seems to be an objective, deterministic "world out there". This division is necessary for science to exist.

But what if there is a deeper truth than just being stuck with the question of whether "I" can control the outcome of events or "I" am powerless to do anything about them. Consider the possibility of access to knowledge before there's an intellectual division into a "me" and "not me", a knowing where the entire notion of whether there's free will or not becomes completely irrelevant. This seems to be the common theme running through various teachings of mysticism, from Zen to Sufism.

I don't think science should try and make use of mysticism, as science starts where mysticism ends (and vice versa), but any attempt by science to wrestle with the question of free will appears to me as pointless as an attempt of a Zen master to wrestle with solving problems in quantum mechanics. It's simply not in their domain.

placebo··on AlphaFold: Using AI for scientific discovery
It is scary for legitimate reasons. It doesn't mean we should stop the advancement of science, but ignoring human tendencies to leverage the best of science to amplify the destructive abilities of worst in human nature is a bit on the naive side.

Whether we are wise enough to handle our intelligence is still an open question.

placebo··on Daniel Kahneman on when to trust intuitive judgment
Those are very reasonable points to explain the way correct subconscious prediction of success works. I wonder though whether this definition doesn't run the risk of creating a closed system of thought, i.e one where you can always refute opposing evidence from within the system without being aware that the system is making you incapable of seeing something else. Specifically, any genuine cases of intuition not due to Kahneman's reasoning (if such exist), would never be seen and always attributed to survivor bias (as long as they don't become a statistical anomaly).

It's probably difficult to build a case against this reasoning, as it seems quite logical - my first thought as a candidate for a counterexample was claims of "love at first sight". Sure, many of those might end in divorce but does that mean that all the successes are just due to being on the right side of statistics or is there something more going on?

placebo··on The Human Brain Is a Time Traveler
>It's not really possible to give a glib, one-sentence description of it.

And yet, you just did.

My definition is poor if you turn it into something simplistic and not realise the vast number of ways and levels of abstraction in which truth can be distinguished from falsehood, which gives rise to various forms of intelligence. It boils down to having a less limiting understanding of the concept of truth.

Intelligent atheists and intelligent Christians can't both be right about what? They can both be right about some things and wrong about other things, but that is true of any two different people, not only any two different groups.

placebo··on The Human Brain Is a Time Traveler
I think that there's another way of looking at it. My definition of intelligence would be the ability to tell what is true from what is false. The ability to predict the future is a by-product of that ability.

regarding what is the nature of truth and the issue of self awareness - that's a can of worms that I'll refrain from opening :)

placebo··on Computer programming as an art (1974)
I'm embarrassed to say that I wasn't aware of Keats' writings and your comment sent me to get more educated about him, which I found very interesting, so thanks for that :)

Not sure in what sense you find the view reductionist, but I suspect it could be from inadequately expressing what I mean

placebo··on Computer programming as an art (1974)
It's a nice distinction. I wonder whether we can go further though, and not even need that distinction. Here's my take on it.

Any human endeavour is worth its salt if it succeeds at discovering and expressing beauty. It can be a mathematical proof, a theory in physics, an elegant algorithm, a painting, a dance, a novel, a relationship - the list is as endless as the number of ways humans can come up with, and can be as deep and complex and subtle as they wish to make it, but it always comes back to finding and expressing beauty.

placebo··on RaptorJIT 1.0: Lua implementation for high-perf low-level system programming
The level of experience, talent and expertise required to dive into LuaJIT development and following Mike Pall's stepping down from active development of it was cause for concern that this would be the end of the road (some even decided to abandon Lua as a result). My optimism grew when I saw this project (and the quotes at the end of it's github page, which capture the issue perfectly) - very glad to see this release and hope the momentum just gets bigger.
placebo··on The future’s so bright, I gotta wear blinders
given there is no real "you" to begin with, who is it that falls somewhere in the middle between "afraid" and "indifferent"? :-)

I understand what you're referring to though, and assume that the very few that have actually fully realised this (and not just on an intellectual level) are not really bothered with death, and not due to lack of awareness of it.

placebo··on The Big Hack: How China Used a Tiny Chip to Infiltrate Amazon and Apple
"Two of Elemental’s biggest early clients were the Mormon church, which used the technology to beam sermons to congregations around the world, and the adult film industry, which did not."

Amused to see some element of humor added to an article on a subject that will have extremely serious consequences, the likes and extent of which are hard to estimate at the moment

placebo··on Nerve implant 'restores consciousness' to man in vegetative state (2017)
could you elaborate? Do you think they really didn't have the condition described? If they did then while more evidence would be helpful in establishing likelihood, it would not make a difference in establishing possibility.
placebo··on NewSQL databases fail to guarantee consistency and I blame Spanner
I did start earlier than the VIC-20 (with TRS-80 Model 2 at school) but you definitely take the title :)
placebo··on NewSQL databases fail to guarantee consistency and I blame Spanner
Guess I win this round, unless there are older farts than me - Commodore VIC-20 with 3.5KB RAM which was plenty for me to do really cool things with in BASIC and 6502 machine language)
placebo··on SageMath – Open-Source Mathematical Software System
It's great to see lots of amazing projects and that people get to have more choice and can avoid being locked into one solution, but one thing I'd like to see more in a description of any product (open source or not) especially when there's a learning curve involved, is the use cases where it would make more sense to take on the effort involved in the learning curve for this particular product rather than others that seems similar to it (at least to the uninitiated).
