well I'm living in Guatemala at Lake Atitlan. We have quite a movement of crypto enthusiasm so the people that are using it are "normal" people who are part of that crypto group. We also have a Lamassu "cryptomat" for people to exchange the local currency to Bitcoin and the crypto group has been advocating people to use Muun wallet, which is easy for the average person to kind of have on-chain and lightning capability.

In Guatemala at Lake Atitlan! I have a lightning node running BTCPay Server on a raspberry pi, and then also a web app that interfaces with it. I can show you the web site, although I'm hesitant to post it here cause i don't know how much traffic it can handle with the internet speeds here haha

I'm not familiar with this space, but from what I have heard... Aren't we talking about NFT's worth hundreds of thousands of dollars? I don't think it's limited to a group of young kids...

Your post has some tension in it that I can't quite place my finger on. Like you want to succeed like the dumb people but you can't cause you're not dumb? I'm confuses then, are the NFT producers dumb if that's the case? Maybe the king of the dumbs.

NFT's in this realm don't really seem like they add value to much, but I am starting to see the value of NFT's more generally speaking!

exabyte··on Is success tied to having rich parents?
It depends on what your metric of success is. More money, individual happines, altruism?

Sure, rich parents will give someone a safety net, but I bet in most cases it yields the kids pissing in the wind.

Are they creating something they actually enjoy doing while earning a comfortable living? That's an intersection that takes a lot of work beyond just having money to find.

I would argue that the real success of a startup is in its potential to grow 'organically' rather than just throwing money inefficiently at it to try and force its success. There's a lot of competition, ideas and people carelessly throwing around money out there regardless, so I think it's a niche that requires much more than money alone to discover. More money is obviously preferred if you do find it though!

exabyte··on Twitter’s founder admits that shutting down the API was “worst thing we did”
The corporate mindset is geared to maximize profit. When you remove yourself from the system for long enough you definitely have a different perspective on things. Maybe they were afraid that it would grow out of control and the system couldn't handle it if programs were automating tweets. I'd say that is a valid concern. So they have to have systems in place to avoid malicious players. Maybe it just wasn't prioritized. Or maybe Jack's philosophy has changed. I don't think it's unreasonable for someone to admit they see things differently now. It's human nature and if anything we should welcome their honesty.

exabyte··on Unlearn rotation matrices as rotations
For me I think the difficulty was just reconciling reality with the concept of a coordinate system. I think it was just some abstract concept that I considered to be out of my cognitive reach of understanding. I just had no way to anchor anything being said to me to a concept I had in my head at the time.

I remember this poor teaching fellow where I went to Lehigh University where I studied Mechanical Engineering. He was foreign and had the honor of teaching us Linear Algebra. He must have noticed that none of us had even the slightest damn clue what he was talking about. So, the class before every exam, he would literally just give go over the exam problems nearly verbatim and solve them. I came out of that class with a good grade and not the slightest fucking understanding of Linear Algebra beyond the very superficial algebraic laws of multiplying tensor objects (i.e., scalars (0-D tensor), vectors (1-D tensor), and matrices).

I'd like to thank Grant Sanderson (3Blue1Brown) and Mike Cohen (Udemy Linear Algebra course using Matlab and Python) for teaching me linear algebra. And don't forget Gilbert Strang, of course!! (find his course on MIT OCW) The visualizations of the tensors transforming provided by the first two are what really made Linear Algebra start to click for me. I want to go back to Gilbert Strang's course now that I have a better geometric understanding of what is happening and appreciate all his wisdom on the subject.

The power that I see in machine learning is the techniques being developed to handle the unavoidable noise in empirical data. I think that poses a large obstacle for traditional techniques although I am not familiar enough to compare.
exabyte··on Website allows you to experience what it is like to live with dyslexia (2016)
I recommend reading the book "Language at the Speed of Sight: How We Read, Why So Many Can't, and What Can Be Done About It" by Matthew Seidenberg.

It starts off with the history of writing, which I actually have to go back and re-read because it's such a crazy evolution. Talk about standing on the shoulders of giants. I can't imagine getting thrown back into the stone age and having to figure out a way to communicate ideas.

It also talks about the fascinating ways that the brain uses different modalities to converge on meaning - really made me thought a lot about machine learning algorithms. It refers to a lot of well-designed studies with results that provide valuable insights into the inner workings of the brain.

It also talks a lot about dyslexia and how it is a rather broadly defined disorder. I'm pretty sure I could be considered dyslexic based simply on how poor of a reader I am. This also, however, could explain why I did better with math and science where you are doing yourself a great disservice to trying to skim the texts. I read that shit at the pace of a snail, but hey, maybe that allowed me to process the concepts better.

exabyte··on 'Did I miss anything?': A man emerges from a 75-day silent retreat
it's all part of the process
exabyte··on 'Did I miss anything?': A man emerges from a 75-day silent retreat
Some breakthroughs I had on my two 10-day silent Vipassana retreats that I did...

Every individual has their own distinct perception of "me". Additionally, my perception of their perception of me is almost definitely incorrect and moreso a reflection of my thoughts. Conclusion : why waste energy trying to play roles based on how I think people see me when it's highly unlikely to be true? There's an interesting novel called "One, No one and One Hundred Thousand" by Luigi Pirandello that touches on this! I also have stopped trying to define the people around me by their physical appearance or habits because I want to encourage them to feel like they can be fluid around me.

Similar to above, I had this revelation that I was putting energy into so many irrational habits just to try to please others. Holidays are a good example. I refused to participate in these traditions that were stressing us all out every damn year. It took me quite a while to actually find a compromise here because I wasn't going to give some arrogant speech to my family that they had to abide by my way, so for quite a while I just attended but hardly participated in the circus. I also no longer just buy random presents for people simply for the reason that I don't want to hurt their feelings if I don't. I've started being more creative and personal with my gifts. It was a bumpy road, I definitely offended some, but it has made the whole experience so much more fulfilling and valuable.

Something else that was interesting is I noticed how vocal I am when I feel shitty as a way to comfort myself and feel secure. I got the shits for a few days during one of the retreats and I didn't want to break the silence unless it was really necessary. I remember thinking crazy stuff like "what if I pass out on the toilet from dehydration and everyone just thinks the bathroom is always occupied when they pass by and I die?" Haha, I hardly ever complain now to people when I feel ill. I usually just analyze the sensation.

Finally, it was just crazy to see my body through that lens of just feeling sensation. Like one day someone mentioned during a group meeting that they were feeling their gums and even their teeth. Next time I meditated I focused on them and was like "Holy shit!! How have I never felt these before?!" (note: it's not TOTALLY silent, you talk once a day briefly in group and have the option to ask questions after lunch to the meditator for your gender who is overseeing the retreat.)

I consider all of these revelations to have kind of become integral to who I am, so in that sense they're benefits have been permanent. I have dealt with Hashimoto's thyroiditis in the past so the energy I save from not doing irrational habits has made a huge difference. I still have some issues in that realm, but I am always learning and improving more about myself based off my new way of observing myself.

I will say one thing that's important though. After my meditation I actually became quite depressed. This was largely due to having gotten a parasite (giardia) from traveling. After I took the medicine, which seemingly nuked my microbiome off the face of the earth, I suffered an immense cognitive dissonance. Despite having had all these revelations on the "surface" of my mind, it took a much longer time for me to modify my habits, which carried a lot of momentum with them, especially situationally, e.g., how you act differently when you're with a friend you grew up with. It really depressed me to watch myself performing old habits that were at odds with this new mindset. This took me years to come to terms with and I still have periods of difficulty, but I'm finally closing the gap between my thoughts and my actions and I'm way more forgiving and understanding to myself. Hashimoto's definitely made this more difficult. Ayahuasca helped me out a ton with these difficulties.

By the way, the Vipassana retreats I did (started by S.N. Goenka) are totally free! You get a room and fed 3x a day. They're all over the world too. You can go to www.dhamma.org to sign up if you're interested. You can donate at the end if you'd like. I personally think aspects of the teaching are a bit antiquated, but overall I'm really glad I did them.

(edited this a decent amount for clarity, almost gave up on posting because it was getting hectic, but I think it's coherent enough!)

Forgive my lack of specificity, as I am quite new to Julia, however, I believe that after the initial compile takes place, you do experience significantly faster runtimes, so you can "forgive" the one time delay.

I think you can also have VS Code just load up the packages you expect to use on a regular basis at startup.

exabyte··on A 2020 Vision of Linear Algebra
There is a linear algebra series on Udemy called "Complete Linear Algebra: : theory and implementation" by Mike Cohen that I really enjoyed doing because he walks you through Matlab demonstrations (code included for Matlab and python. I adapt to Julia using the PyPlot wrapper for Julia).

I particularly like his videos because he breaks them down into small bites that are easy to work into your day and he's a great teacher.

exabyte··on Ask HN: What scientific phenomenon do you wish someone would explain better?
Here are things that I consider to be defining properties of human consciousness:

a) The ability to observe an instance of a multidimensional universe, each instance a mapping of a point moving along a continuous trajectory whose direction is constrained by the arrow of time (i.e., increasing entropy)

b) the ability to impart a force to change the direction that trajectory follows

exabyte··on Ask HN: What scientific phenomenon do you wish someone would explain better?
re: Wave-Particle duality : Imagine that the "particle" in its natural state is a wave of energy that pervades spacetime. Assume we are interested in forcing it to reveal itself as a localized "particle": the amplitude of the its waveform as a function of space and time will tell you the probability of it revealing itself as such in that location at that time. Note the wave form is complex, so in order to get the actual probability you have to calculate the magnitude.

The idea is that it is in this waveform until you do something to observe it. Observation requires an exchange of energy, i.e., an interaction. This is why there is always uncertainty, because in order to observe something, that which observes has now intimately interacted with the waveform in order to cause its "collapse" into what we consider to be a particle. A particle very well may just be a highly localized energy that we perceive to be "solid"

You can't, for example, try to get a measurement of the location of a photon without putting a measuring device which absorbs the energy of the photon, modifying its wave function and thus the probability of where it will decide to reveal itself at that point in spacetime.

note: I consider energy, fundamentally, to simply be the consequence of fluctuating. The fluctuation of one thing can interact with the fluctuation of another and, minding conservation, transfer "fluctuation". The direction of that transfer of energy relying may be due to the fact that entropy always increases along the arrow of time, i.e., energy likes to spread itself out just as heat goes from high concentration to low concentration.

exabyte··on Saving Florida’s Oranges Starts with Soil
I studied engineering/physics and I've dipped into the agricultural field the past year having developed an interest in it, also observing the operations of a local organic farm.

It's actually quite fascinating. I'm currently following a course created by Dr. Elaine Ingham, who is a microbiologist that studies soil biology and has done some really amazing research. She also worked at Colorado State University, which can't be a coincidence!

Here's the lowdown of what happens, because we've been getting this wrong for centuries in agriculture. The nutrients (N, Ph, Mg, K, etc) are bound to materials in the soil ranging from rocks to pebbles, to sands, silts and clays. We have been destroying the soil by tilling practices and large machinery which are creating compaction layers that lead to anaerobic conditions causing the "good" biology in the soil to die and also preventing roots from growing to the depth they need. It turns out that the way that the nutrients become available to the roots of the plant is by means of the bacteria/fungi breaking their bonds from the previously mentioned materials (rocks, etc) and then, even more interestingly, they get eaten by higher trophic level predators who shit out the nutrients in plant available form!

Some fun facts: - The roots release sugars (photosynthates) into the soil which attract particular bacteria/fungi based off its needs for nutrients AND pH requirements (bacteria release substances which raise pH and fungi acids which lower it, and the pH can vary on the scale of micrometers based off this)

-Bacteria and particularly fungi (if you haven't studied fungi, go watch Paul Stamets on Joe Rogan, cause they're incredible organisms https://www.youtube.com/watch?v=mPqWstVnRjQ) create symbiotic relationships with the plant, each one feeding and protecting the other.

- Many tests which tell you your soil is low in nutrients can be complete bullshit. Extracting agents will yield different results, and if, for example, you're only looking at soluble nutrients, you're missing the fact that they're available but just bound up chemically and require the biological activity.

- dousing your soil w/ inorganic fertilizers are hardly short-term solutions because 1) if the soil has no structure to it, then they will wash immediately out with rain and 2) you're literally dissolving salts into the water of the soil, making the water unavailable to the plant and can stress the plants more. Sure, they might get a quick dose of nutrients but you're playing a losing game.

- there's a whole bunch of other stuff. Elaine's course available on www.SoilFoodWeb.com, it's a bit expensive, but I find it fascinating and I'm barely halfway past Ch 2. She basically gives you all the science behind it and the know-how of how to address the problem yourself, not rely on a product. She's a total G, it's really fun listening to her and hearing about the history of her research. https://en.wikipedia.org/wiki/Elaine_Ingham

I'm not sure what this Rhizolizer brand is, but I presume it's not far off from a "tea" made from vermicomposting (i.e., you feed your compost to worms and they shit out a magical biologically rich and diverse "casting" which you can utilize to put the healthy biology back in your soil)

exabyte··on Neural correlates of the DMT experience assessed with multivariate EEG
You absolutely want to find an experienced group in order to guide you. Never do it while taking prescription meds like anti-depressants, opioids or others. Ayahuasca is very different from taking straight DMT. I haven't done the latter, but the experiences I have heard differ significantly in certain respects. You should never do Ayahuasca recreationally in the spur of the moment.

All that being said, there are experienced groups, in Holland for example, that lead safe group Ayahuasca ceremonies, such as a long weekend with 2 ceremonies. Peru is an option but it's much more of a raw experience and less gentle to a western mindset.

exabyte··on Neural correlates of the DMT experience assessed with multivariate EEG
I've taken Ayahuasca more than once and every ceremony was something that I could integrate into my life in one way or another. As with all similar substances, the setting and preparation make a huge difference, it should never be done recreationally in the spur of the moment but rather with guides who have experience. NEVER TO BE DONE WHILE TAKING CERTAIN MEDS LIKE ANTIDEPRESSANTS, OPIOIDS, ETC I have never done straight DMT, but from what I have heard I consider it to be a very different experience. Ayahuasca is a very unique experience to each individual although there are indeed stories that are shared such as seeing "machine elves", confronting snakes, feeling unbound from time, meeting a higher entity, etc.
