What everybody really wants to know about the recent grudge match between @RealKidPoker and @DougPolkVids is: Why did Dan agree to it? Since there isn't much good commentary, I'm now going to engage in rank speculation (thread)
(For those not in the loop Doug entered as the favorite and won by what's probably about the amount expected)
First there's the explanation Dan himself gave: That he has some financial interest in GGPoker and this served to promote it, although not as if it had been able to host directly
There's undoubtedly at least some truth to this, although the amount he lost seems big enough that it's unlikely to be the whole story. Of course it wasn't clear beforehand that GGPoker couldn't host, so that may have thrown a wrench in things
It's important to point out that there's nothing unethical about this. There are financial ties which could produce conflicts, but this isn't one of them
It's also theoretically possible that Dan could have put in side bets against himself and thrown it. I find that highly unlikely. He's maintained a mostly good reputation fro a long time and is accustomed to taking big financial risks but not \
big risks as far as his reputation/potential legal prosecution goes. Also he just doesn't seem like one to ever do that. That said Dan may have gotten +EV placing side bets on himself, which is totally ethical
It seems likely that the line in this one was a bit too far towards Doug. People underestimate volatility in these sorts of things and this was a very noisy match upswingpoker.com/hu4grudge/
Dan studied for this one quite a lot, and it's an important bit of context that if the Dan of today played against the Doug of the era when he was the best heads up player in the world Doug would be crushed. Poker strategy has come a long way
Dan of course got a lot of improvement to his brand value, in both amount and tone of coverage. That could go a long way to justifying the -EV of the actual play. But likely more important, Dan got the value of his studying
It seems Dan was looong overdue for getting taught proper GTO-based poker strategy and his play is massively improved as a result. This was heads up, which is an unusual format, but the same foundations apply to 6-max as well.
Even for players with a highly exploitative approach it's always better to know GTO strategies so that you can accurately understand your opponent's deviations from those and exploit them. If you don't know GTO, you don't know what's a deviation
Of course it wouldn't take many super-rich people wanting to play against Dan HU for him to make back a big chunk of the money he just lost, which could easily happen after all the recent press
It's also very likely that Dan just plain enjoys playing and promoting poker and is willing to take a hit for it. Or maybe he's degen and can't help himself. It's hard to say what, if anything, is the difference between those two.
Or maybe Dan wanted the opportunity to bury the hatchet with Doug. I don't think that was particularly planned for, he's just a nice guy and being a good sport is a good way to make friends with people (as is losing a million bucks to them)
On that subject I should probably give my opinion about 'more rake is better'. Obviously under many (probably most) circumstances more rake just plain pays out more money, but there are narrow scenarios where it's better for someone because it gets players to drop out
It's relatively easy to see how this can help the fish. If the pros drop out, the fish are now losing rake but not both losing rake and directly losing money to pros. This isn't always the case, but it certainly can happen
The same phenomenon can result in taxes on financial transactions being better for bona fide traders, because it puts hedge funds out of business and distributes the spread directly between traders.
Even more straightforwardly financial transaction taxes can stop people from front running because a front-run transaction is two exchanges which doubles the taxes paid. Amounts and situations are of course very important here but this should be taken seriously
Anyway, back to poker. In terms of pros there are very narrow situations in which the better pros can be better off with more rake because it knocks out the worse pros and now the better pros aren't losing money on rake on pots they're trading with the worse pros
This of course is coming at the expense of someone. The only way all pros can do better here is if the people who drop out were 'semi-pros', basically good recreational players who were at break-even.
Being a professional poker player will inevitably be very cutthroat. There's a limited supply of dumb money to claim, and not much barrier to entry for people to pursue it, and an ever growing set of resources for people to improve their game
In any case, thanks again to @RealKidPoker for being such a good sport and providing so much entertainment. I hope your improved game serves you well in the future

Some thoughts on RandomX. The audits are more useful than the docs on this one (thread) github.com/tevador/Random…
Oddly the pop writeups babble on about virtual machines and such instead of straightforwardly saying it's based off Argon2. That's something which one should be proud of instead of obfuscating.
From the audits it's clear it went about how you'd expect. Some people with more CPU than cryptography experience took Argon2d and applied mixing functions which are reasonably spread out across the functionality on a standard CPU

Came across some discussion the other day of academics talking about how hyperinflation killed Mojo Nation. Don't have a good link (maybe it was Ian Goldberg) but will reflect on Mojo Nation a bit (thread)
Mojo Nation was a glorious failure. It went down in flames, but directly lead to BitTorrent and Bitcoin. There are few failures anywhere near that successful.
I can confirm that hyperinflation did in fact happen in it, although I haven't thought about it much, and hadn't realized that that had been studied and the learnings incorporated into later projects, most notably of course Bitcoin.

It's a bit emotional for me to talk about this, but I will say that Len posted pseudonymously on the cypherpunks list constantly, including at least one fleshed-out and long-lived handle, and even I didn't know what it was leung-btc.medium.com/len-sassaman-a…
Also I have a vague memory - mostly because Len told me about it and I wasn't paying close attention - that there was a nym called Product Cipher which pseudonymously posted the first ring signatures implementation to cypherpunks and then disappeared.
The implication with that one seemed to be that it was Hal or Len or some combination of the two, very unsure though, and don't know if it got clarified later.

Got Clubhouse working again. It seems to have a better idea what it is now. It's talk radio. Like, exactly talk radio. Talk radio is fairly popular, and if it stays apples-to-apples the same there's no reason an app couldn't wipe out that whole industry, so it may do well
That said, the usage numbers still aren't terribly impressive, maybe a few thousand simultaneous users spread across a dozen channels at the most, which is decent but needs a lot more growth to be a real success
The content seems a lot more diverse than before, although when VCs are on they still seem to be trying to fit all the negative aspects of the 'tech bro' stereotype they possibly can. It's so weird how that stereotype is pinned on founders who are rarely that way

Fixing the post office's finances is entirely doable. It has available a business model which would turn it to profitability quickly (thread)
The new service is: Portable addresses. You get one nationwide PO Box which never changes, even when you move. When you move you simply tell the post office where you're moving and on what day and all your personal packages get rerouted
It costs X/month. If X was $20 I personally would immediately sign up, stay signed up for the rest of my life, and never think about it. So would a lot of other people. That adds up fast.

Serious question: What is an NFT? Meaning, what is its technical functionality? (thread)
From the descriptions (and very opaque specs) it seems an NFT is a singleton (or group of singletons, but that's just because contracts in the EVM are heavyweight) which is transferable and has a current value of some kind
And it's important that anyone can go look up this value on the blockchain? Or that someone can prove to someone else what the value is? And the database of the singletons and what they represent is held somewhere or widely distributed?
