Unfortunately, it's not that easy. Axon terminals of neurons release neurotransmitters. We know of dozens of different types, but are not certain that we know about all of them yet. The same synapse can release multiple different neurotransmitters too, with one or more released depending on the axonic signals. And what to these chemicals do? It depends! There are receptors on the post-synaptic cell that respond to neurotransmitters, but there can be multiple different receptors that respond differently to the same neurotransmitter. Again, we aren't sure we know about all of them. The post-synaptic neuron is probably also listening to neurons of other types that signal using different neurotransmitters that it uses to determine if it should transmit an action potential or not. Oh, and invertebrates (like nematodes) send graded potentials (not action potentials like us vertebrates usually do) where the signal strength can vary.

In short - we are a long way from being able to simulate a nervous system. Our knowledge of neuronal biochemistry is not there yet.

> This sounds like it is a third party (maybe just a small group of devs?) doing all the work

Just as a quantitative side note here — tinygrad has almost 400 contributors, pytorch has almost 4,000. This might seem small, but both projects have a larger people footprint than most tech companies' headcount that are operating at significant scale.

On top of that, consider that pytorch is a project with its origins at Meta, and Meta has internal teams that spend 100% of their time supporting the project. Coupled with the fact that Meta just purchased nearly 200k units worth of AMD inference gear (MI300X), there is a massive groundswell of tech effort being pushed in AMD's direction.

> wouldn't AMD just invest in doing this themselves, or at least provide much more support to these guys?

That was actually the point of George Hotz's "cultural test" (as he put it). He wanted to see if they were willing to part with some expensive gear in the spirit of enabling him to help them with more velocity. And they came through, so I think that's a win no matter which lens you analyze this through.

Since resources are finite, especially in terms of human capital, there's only so much to go around. AMD naturally can now focus more on the software closer to the metal as a result, namely the driver. They still have significant stability issues in that layer they need to overcome, so letting the greater ML community help them shore up the deltas in other areas is great.

The 'fun' things with shorts is that they have a fixed upside and infinite downside (ie if you go short $1000, the most you can earn is $1000, but you could lose any amount of money and much more than you invested. This is the opposite of buying a stock, where if you invest $1000, the most you can lose is $1000, but there is no limit to how much you can earn). You can be perfectly right 9 times out of 10, but that 1 time you're wrong can quickly wipe out everything you made from being right those 9 times.

> In high school, we had a Netware 3.12 environment, and the Guest account was enabled, albeit with very limited privileges. But for some reason, Guest could still use NET SEND, which popped up a little message in the bottom row of the destination machine's display. > ...Nobody noticed that these messages came from GUEST

You mention Netware, but as I recall the Netware function you describe was just "SEND" and "NET SEND" was a Microsoft networking thing. (But maybe there was some integration between the two after my experience with Netware, who knows.)

I mainly wanted to say, as someone who used/abused a Netware network in high school, I disassembled the SEND program and discovered that the username included in the message is not authenticated at all -- the IPX (or NETX, I forget which) software interrupt just took a string, and the SEND executable formatted the username into this string. So by crafting your own SEND program that used the software interrupt directly, you could easily forge any username you wanted. So you could very easily send a message from "ADMIN". :)

This should not be construed as a confession of any network shenanigans that may or may not have occurred at my high school. ;) :D :)

i would rather ask one to think, what evidence is there that we cannot do brain on non-gooey stuff?

If i take every atom/molecule from one brain (assume a snapshot in time) and replicate it one by one at a different location, and replicate the external IO (stimulus, glucose...), what evidence do we have that this won't work? likely not much

Now instead of replicating ALL the atoms/molecules exactly, I replace one of the higher level entities like a single neuron with a computational equivalent - a tiny computer of sorts that perfectly replaces a neuron within the error bars of the biological neuron. Will this not work? I mean, will it not behave in the same exact way as the original biological brain with consciousness? (We have some evidence that we can replace certain circuits in the brain with man-made equivalents and it continues to work.)

You know where I'm going with this... FindAll, ReplaceAll. Why would it be any different?

---

If i had to argue that it wouldn't be the same, here's a quick braindump off the top of my head:

- some entities like neurons literally cannot be replicated without the goo. physics limitation? but the existence of the goo is a proof of existence. but still, maybe the goo has properties that cannot be replicated with other substances

- our model of the physical world has serious limitations. on the order of pre-knowing-speed-of-light-limitation. maybe putting the building blocks together does not create the full thing. maybe building blocks + magic is needed to create the whole.

- other fun limitation of our physical model

Thought I'd drop my prank as well. In highschool early 2011-2013ish QR codes were just becoming a thing. We had a mild vendetta against the year book committee due to the pricing of the yearbooks and their cliquey group.

We copied their "Reserve a year book early poster and save". Then used photoshop to edit it to say "50% off your year books with this QR code". The QR code then linked to a gorilla eating a taco (google this its pretty funny), adding to confusion. The year book committee had a FREAK out and sent out a mass email that the QR code was fake and not to follow it and you COULD NOT GET 50% off a year book no matter what link you followed. Needless to say sparked more interest in said QR code and soon the whole school had loaded a gif of a gorilla eating a taco.

(aside: I'm not especially arguing with you; just thinking out loud in response to what you wrote)

> Something waddles, quacks & lays eggs because it is a duck.

Or: something does those things, period. We notice several such somethings doing similar things, and come up with an umbrella term for them, for our own convenience: "duck." I'm not sure how far different that is from "is a duck", but it feels like a nonzero amount.

I guess where I'm going is: our labels for things are different from the "is-ness" of those things. Really, duck A and duck B are distinct from each other in many ways, and to call them by one name is in itself a coarse approximation.

So if "duckness" is a label that is purely derived from our observations, and separate from the true nature of the thing that waddles and quacks, then does some other thing (the robot duck) which also produces the same observations, also win the label?

Luckily, I'm a solipsist, so I don't have to worry about other things actually existing. Phew.

> Curious if any superfans think it would be better experienced as the original in an emulator or similar.

(superfan checking in) -- I still believe the definitive release is the original `realMyst (2000)` (Sunsoft). https://archive.guildofarchivists.org/wiki/RealMyst . If you only ever play one version, that's the one to play. GOG maintains a beautiful version of this (that works well even on modern Windows), but Cyan de-listed it from GOG a while back, so you can't technically buy fresh copies anymore.

Don't mistake this for "Real Myst: Masterpiece Edition", which is (sorry Cyan), not very good. They imported the old assets into Unity for the re-release, and then did some random texture/asset swaps, the lighting and mood didn't survive the import and is all randomly weird -- strongly recommend ignoring this one.

The original release is good if you want the original experience - https://www.gog.com/en/game/myst_masterpiece_edition

And the new Myst (2021/VR, Unreal Engine) release is wonderful and beautiful, but is more of a re-make to modern gaming sensibilities.

> but worse in every conceivable way

I always had an issue with that sentence (and I heard it a lot). Why would experienced software developers always come with a solution worse in "every conceivable way" when implementing logic answering a problem they're having, which would have the huge advantage of being tailored for their own needs?

I'm more of a library developer than an application one but I've seen that many JS webdevs have an aversion toward trying things themselves - instead always going for the most huge/"starred" dependency when they can. I'm not sure the impact of this philosophy is always better for a project's health than the total opposite where you would just re-invent your own wheel.

I do have seen multiple attempts at doing a specific homemade architecture that worked out well for some applications with very specific needs even 10 years later (For example I'm thinking about a 500k+ LOC JS webapp - not intended to be accessed on a desktop browser, but that's not the only successful long-lived JS project I know with their own archi). And I guess a lot of webapps do have their own specific needs where the "default framework" solution leads to some inefficiencies or hard-to-maintain / understand mess.

Haven't they already reinterpreted "two terms" to mean "two consecutive terms" anyway?

When you have your own Supreme Court it's easy. The next step will be to declare that two consecutive terms is actually just one long term, and so on. Every dictator does something like this - not always the exact thing, but something like it, some flimsy excuse and if everyone goes along with the excuse, they gain power.

> F# is where the language designers can push the boundaries

It really isn't, not anymore. F# now evolves conservatively, just trying to remove warts and keep up with C# interop.

And even then some C# features were considered too complex/powerful to implement (e.g. variance, scoped refs) or implemented in weaker, incompatible ways when C#'s design is considered messy (e.g. F#'s non-nullable constraints disallow value-types, which breaks for some generic methods written in C#, sadly even part of the System libs).

"Software simulations" is a working title but it is sort of a new kind of thing we're trying to do and describe - definitely room to improve.

Our goal is to simulate every function and aspect of your application and in doing so provides both a test suite and demonstration artifacts. it's akin to an intelligent, semantically aware fuzzer that is creating both good and bad results (vs. a fuzzer just creating bad results with the intent of breaking things).

It is connected to your code via a GitHub app with read permissions and the ability to comment on PRs when analysis happens.

Let me know if this helps (or doesn't!). I think it's a little different from what you're envisioning but you're not far off.

Actually komi in go solves the problem that black won nearly all the even games between strong players, except when white was an exceptionally strong player.

Hence the original 4.5 points komi about 100 years ago. The half point is the part that turns a draw into a win for white, that starts playing after black. But it's not strictly necessary: we could state in the rules that white wins draws.

Black started playing less conservatively and komi was soon adjusted to 5.5 points. It became 6.5 points at the turn of the century. It's 7.5 with Chinese and area rules.

This variant of chess seems to me potentially unfair to the player that gets a bad starting position, one that loses most games or that could even be winning but only with a narrow and difficult path to find. It could work in a tournament if all players have to play all the initial configurations. In thnk

"Able to be replicable" is a far cry from being practically replicable.

We are unable to get two biologically identical (or at least extremely close) brains of identical twins to develop in the same way, let alone two distinct brains, or a simulated version of a brain.

The claim is potentially equivalent to a claim that since universe is theoretically computable, we'll eventually be able to simulate it.

Once swapped the system disc of a netware server live. Can't remember why exactly, I think it stared to count bad sectors as we watched and we needed to keep it alive copying the data to the new, to-be system disk. Then we made sure, nobody was logged in, it was about midnight, hit Alt-LeftShift-RightShift-Esc and while Netware paused in the kernel debugger, swapped the disks. Continued the debugger and - it worked :)

> Nice try. We are not at war with these countries and not even close to it either. Trump is the most non-interventionist president of the last few decades. This is an empirical and historical fact.

Trump has only been in office for two months. He's clearly threatening to take intervention to never before seen levels.

> Obama in Executive Order 13576 ...

Obama's executive order and actions were within the rule of law, "By the authority vested in me as President by the Constitution and the laws of the United States of America". Very many of Trump's are not; Trump openly challenges and disregards any limit from law or the courts.

> [DEI/ESG:] Yes which is great - this is an example of reducing the size and scope of government.

It doesn't matter if you think it's great. It's stopping private organizations from doing what they choose - that is government using its power to compel behavior.

> There is a literally an EO on preventing online censorship

Human rights - freedom - is universal or it's nothing. It's just Trump protecting his friends and persecuting his enemies - the opposite of freedom.

They are arresting people in the street and deporting them for speech, forcing schools to censor students and faculty, forcing leaders of business and journalism to avoid criticism and even to support him - as just one example, look at the law firms he is extorting for representing parties critical of him.

It's also oppressive to force private companies - social media companies - to adopt policies Trump prefers, including about moderation.

> scepticism of the validity of learning institutions

Can confirm, this is solidly wedged into my opinions now. There were a lot of other experiences after this to compound that feeling.

In High School, I started looking aggressively for a less traditional path and fortunately found one. It really saved me, because I was forced back into the traditional environment in Senior year of high school, and my grades tanked from top-of-class to "you might need summer school to graduate" level

Things got a lot better in college, because that experience (among others) helped me effectively navigate the institution, jump directly into more advanced coursework, and earn more freedom to study things that were interesting to me.

I did get a job in my field out of college. So, my college pedigree was useful practically (though not really any knowledge I got there). But, I'm self-taught dev now, which is an amazing fit for my experience and attitude.

Get a modern version with higher-resolution graphics, better color, and other playability improvements. Masterpiece Edition is my favorite version I've played. I think there are a couple of even newer versions; I don't know how they compare.

I wasn't a fan of RealMyst. The game's environment wasn't originally designed for the player being able to wander freely, so it doesn't really add much to the game and even detracts from it in some respects.

Hi teleforce, thanks! Your project sounds very interesting as well.

That actually reminds me, at one point, a researcher suggested looking into geophone or fiber optic Distributed Acoustic Sensing (DAS) data that oil companies sometimes collect in Alaska, potentially for tracking animal movements or impacts, but I never got the chance to follow up. Connecting seismic activity data (like yours) with potential effects on animal vocalizations or behaviour observed in acoustic recordings would be an interesting research direction!

Regarding data access:

Our labeled dataset (EDANSA, focused on specific sound events) is public here: https://zenodo.org/records/6824272. We will be releasing an updated version with more samples soon.

We are also actively working on releasing the raw, continuous audio recordings. These will eventually be published via the Arctic Data Center (arcticdata.io). If you'd like, feel free to send me an email (address should be in my profile), and I can ping you when that happens.

Separately, we have an open-source model (with updates coming) trained on EDANSA for predicting various animal sounds and human-generated noise. Let me know if you'd ever be interested in discussing whether running that model on other types of non-stationary sound data you might have access to could be useful or yield interesting comparisons.
