cowtools··on JPEG of Shakespeare is also a zip file containing his complete works (2018)
I am surprised that it survives twitter's image compression. I'm not familiar with JPEG format, but I'm familiar with PNG. I guess it's using some zlib-compressed EXIF-like metadata field, seeing as ZIP also uses DEFLATE/zlib/whatever?
cowtools··on Fake Books
I don't think it's that scary. I mean it's basically spam isn't it? The only thing new is the volume in which you can produce surface-level-indistinguishable spam.

It is now cheaper to produce lots of flowery, meaningless text that is full of definitions. I suspect that the future of literature is more concise and externally-meaningful writing.

Amazon is a terrible marketplace insofar as the rating system isn't sybil proof. this crap slips through the cracks.

cowtools··on Kiwifarms Dropped by Their ISP
Net neutrality is about regulating ISPs to provide the same delivery service regardless of the content being sent.

What you're describing is just a single implication of net neutrality involving self-bias of ISPs.

>The net is not politically neutral; it arcs toward progress

Humble the assumptions you make on the direction of progress

He seems to be hosting it himself, it's just that his counterparts on the other end of political extremism have campaigned to yank the cables out from under him.

The internet is built on peering relationships at the end of the day. Alice doesn't get to see Bob's website unless the intermediaries agree. In this case, the intermediaries are being made to disagree with Alice and Bob.

cowtools··on Crazy crypto mining story from 2013
>people won't be paying for their coffee on-chain (assuming inflation doesn't do crazy things to the price of a cup of coffee!).

Okay, but those LN transactions clearly depend on the security of their multisig channels without subsidizing the miners through the fee market.

cowtools··on Crazy crypto mining story from 2013
>you will always reach an equilibrium point where it will be profitable.

That is my point- that equilibrium point will eventually be low enough that 51% attacks, selfish mining attacks, etc. become feasible and highly desirable to execute.

>It's low reward, extremely high cost

It is currently low reward/high cost. But it will eventually not be.

>and 'easily' undone if the market so agrees.

False. Bitcoin has not made a hard fork in how many years? Can you make a hard fork faster than the attacker can "cash out" to crypto-crypto exchanges? Highly doubtful.

>Whoever mines the block will get no coins, but will get all revenue from the fees attached to whichever transactions are processed.

... which is dependent only on the fee market, and currently amounts to a small fraction of total block reward.

cowtools··on Crazy crypto mining story from 2013
>so far, by-and-large, the proportion of block profit coming from transaction fees has increased, as expected:

of course it has. I am not talking about the proportion of block profit, I am asking how you expect the total block profit to stay the same from just fees. The network will have to survive when the proportion will eventually be 100%

Why do you expect transaction fees to increase?

cowtools··on GitHub Copi­lot inves­ti­ga­tion
Yes, that's the other outcome, which is the industry getting GPL'd to death for using this. But I don't think there is an established precedent when it comes to this.

I don't know much about AI/SL but I think the logical outcome is that using a transformer to generate source code is going to result in an over-trained system that produces sections of code verbatim because of the relative size of the space of all valid programs vs the space of all possible programs. It's not like art where you get soft failure if a single pixel or word is wrong: the inclusion, exclusion, or replacement of a single instruction or symbol is enough to introduce fatal bugs into a computer program. If the system doesn't have the capacity to understand programs generally (which it probably won't if it's just a transformer), then you're going to end up with a system that spits out samples from training data that do work.

cowtools··on GitHub Copi­lot inves­ti­ga­tion
Of course it is cherry picked. The idea is that it allows you to INTENTIONALLY void any copyright you want.

So let's say I obtain an illegal copy of microsoft windows' source code. Under this precedent, what stops me from just (overfitting) training a neural network to produce the source code verbatim, sans any license notice?

But it doesn't end there. What stops me from making a neural network that exactly reproduces the bytes of Illegally_Ripped_Disney_Movie.mp4 that I obtain from the pirate bay? Copyright need not apply.

At what point can the neural network I've described (which is intentionally designed to violate copyright) distinguishable from a neural network like Copilot and others which violate copyright extrinsically?

It strips GPL, or any license.
cowtools··on Chainalysis CTO said blockchain is easier to trace than paper money
Sort of, but not really. It is a very nuanced probabalistic attack. The problem is fundamentally that you need others to use your outputs as decoys in order to have plausible deniability.
cowtools··on Chainalysis CTO said blockchain is easier to trace than paper money
I doubt it. Bitcoin was simply the combonation of two well-understood things: hashcash and cryptographic signatures.
cowtools··on Chainalysis CTO said blockchain is easier to trace than paper money
The fees increase with demand, but throughput does not. Bitcoin's current incarnation cannot scale. If it is cheap to transact now, it is only because the demand for its use as an actual currency has been reduced since the last fee explosion.

If everyone in the world tried to use bitcoin as a replacement for bank transfers, etc. then the fees would be astronomical

cowtools··on Chainalysis CTO said blockchain is easier to trace than paper money
It's irrelevant

No, This is incorrect

privacy through voluntary swaps is not sybil-proof
cowtools··on Chainalysis CTO said blockchain is easier to trace than paper money
I suspect chainalysis is describing some "poisoned output attack" with respect to monero. See: https://m.youtube.com/watch?v=iABIcsDJKyM

The problem is a well-understood but innate limitation to all sender-obfuscating cryptocurrencies.

cowtools··on GitHub Copilot, with “public code” blocked, emits my copyrighted code
I am going to make a robot that burns your house down. You might think this is unethical, but what you expect me to do? Implement an oracle to the US court system?

You might think it's unreasonable to build such a house-burning robot, but you have to realize that I actually designed it as a lawn-mowing robot. The robot will simply not value your life or property because its utility function is descended from my own, so may burn your house down in the regular course of its duties (if it decides to use a powerful laser to trim the grass to the exact nanometer). Sorry neighbor.

What do you expect me to do? NOT build this robot? How dare you stand in the way of progress!

cowtools··on GitHub Copilot, with “public code” blocked, emits my copyrighted code
The problem here is that copilot explots a loophole that allows it to produce derivative works without license. Copilot is not sophisticated enough to structure source code generally- it is overtrained. What is an overtrained neural network but memcpy?

the problem isn't even that this technology will eventually replace programmers: the problem is that it produces parts of the training set VERBATIM, sans copyright.

No, I am pretty optimistic that we will quickly come to a solution when we start using this to void all microsoft/github copyright.

cowtools··on /r/StableDiffusion – Mod here – My side of the story
It's deceitful for discord to use that language because it implies some level of independence.

A VPS service like AWS goes out of their way to specify that it is a "virtual server". the product they provide is analagous to real server hardware and largely interchangable with other server hosts.
