CS professor Chris Okasaki, known for his book on purely functional data structures, also played board games and he came across this phenomenon. He realized that it could be modelled as a bipartite matching problem, and wrote a MUCH faster program to manage math trades.

I guess it can be made even faster now in theory.
It's mostly of theoretical interest except for some possible niche applications, I'd say. For a math trade type of problem, you'd just go ahead and use the old algorithm with an RNG.
Another famous result of this type was AKS primality testing. Randomized algorithms like Miller-Rabin were known for a long time, very reliable, and quite simple to implement, but AKS was an important theoretical advance because it didn't use random inputs. I think everyone still uses Miller-Rabin in practice.
Identity-building projects need simple stories, genetics (or history generally) rarely gives them.
I know other examples of relative ethnic stability: most of Northern Europe broadly has the same ethnic geographic boundaries as 1500 years ago (excepting the slavic / proto slavic things), the Basque, the Sardinians, Bretons and Bearnese, Tirolians, Kabyles, Laz "Greeks" (vanishing since WWII).
By some measures also Egypt (coastal cities excepted) and Iran.
It makes sense that they would be the first to use AI for whatever they can get away with.
Individual frames of anime, they generally had a lot more 'packed into' the frame. This is part of the reason the motion wasn't great; they were spending most of their time budget of big flashy frames.
Disney, when they made animation, was more focused on hyper stylized characters that moved in a very specific way. There's an entire book on how to make animation 'The Disney Way." Some friends of mine ended up working in animation, and that's how I learned about this.
> In 1985, Bill Schultz and a group of investors—including company employees and external companies like Servco Pacific Capitol—purchased Fender from CBS for $12.5 million and renamed it "Fender Musical Instruments Corporation" (FMIC).
> Ownership changed in December 2001, when private equity firm Weston Presidio bought a controlling stake in Fender for $57.8 million.
> Longtime investor Servco instead bought out Weston Presidio, with TPG Growth as an equal partner.
> In 2020, Servco bought out TPG Growth's stake, making them Fender's majority owner.
A long history of private equity ownership. I'm not sure CBS owning them would be much better, which started in 1965.
As much as I like to blame private equity for the downfall of once great companies, I'm not sure how to feel about this one, as they've been investor owned and passed around for decades.
It's the 2000-2020 exchanges that were detrimental
I play a Gretsch... which interestingly is actually "controlled" by Fender after looking it up; still owned by the Gretsch family
(It’s surprisingly hard to think of a motivating example.)
Too many Clapton lawyers have gotten hip to boutique builders. Fender would rather make them buy a $5000 Masterbuilt Custom Shop Deluxe Roadworn Heritage Double Relic No-Caster than a Tom Anderson or Suhr. Same for kids buying Harley Bentons and ESPs - a $1000 Indonesian-built instrument is their future if Fender has anything to say about it.
The thing is, they already do that, or have in the relatively recent past. Arguably, they invented that move in the 1980s when they started selling non USA/Japanese models as Squier models.
There's only so much that brings them, though, and guitar music ain't what it used to be. The pie isn't growing very much (maybe at all) and now there's competition trying to capture more of the market.
Would Bill Schultz have done the same thing if the 80s and 90s hadn't been so good to rock music? Hard to say, but if the alternative was "No more Fender", maybe.
If I have a box at Digital Ocean and I'm communicating with it with TLS1.3 using a Let's Encrypt cert that I generated, where, exactly, does this magical MITM box come into play?
Do you know what hypervisor is managing it? :)
And these days (especially post-Snowden), many (most?) companies encrypt data when sending between servers within their own (private network) infrastructure.
Yours and others' claims that it's impossible and nonsensical is based on lack of understanding.
Yours and others' claims that things somehow got better after Snowden is just a completely baseless statement - if you actually looked into what happened post-Snowden - absolutely nothing was done to prevent NSA spying on any communications they want, in fact it got significantly worse.
lol, no, it's really not.
> Also when talking about encryption between servers within datacenters you seem to be missing that in order for such multi -stage/path encryption (separate certs/keys) to be possible the data first has to be decrypted at each point
Why would I want the data to be decrypted at each point and why would datacenters do that? Encrypting and decrypting data is expensive computationally, so that's not how things work at all. There's no need to decrypt data to know where it needs to go. That's why we have TCP/IP and other similar stadards.
The datacenters can maybe add another layer of encryption on top of my data as its moving around their networks, but there's absolutely no way for them to strip off my encryption.
> Yours and others' claims that things somehow got better after Snowden is just a completely baseless statement
Things didn't magically get better. A lot of people worked hard to improve the overall security posture of the industry.
Yeah it definitely is lol.
> Why would I want the data to be decrypted at each point and why would datacenters do that?
When we talk about data that is sent for processing to a 3p server (like anthropic in this case) the data obviously needs to be decrypted to be processed.
As to why data is decrypted at each point in a typical large backend system - because other than network routing there are presumably multiple services that need to receive and act on this data somehow - you're not just sending encrypted data around to random servers.
> there's absolutely no way for them to strip off my encryption.
You don't seem to understand that you have no control over the encryption or decryption done on the backends of cloud services you use. I don't know how to make it more simple and obvious at this point.
Again, the context here is Anthropic and sending your data to their (or any other big tech API). But even if we move away from this model and suppose you are running your own services on rented cloud VM - then it should be obvious that you don't have full control or even access to this VM... any actor with access can install or modify any software, install/modify EBPF, modified crypto libraries, etc. - you have absolutely no control or say over this.
> Things didn't magically get better.
Things didn't get better at all, they got much worse.
I think they mean the data must have existed in plain text before it was encrypted, and will exist in plain text after it is decrypted.
At some point “your” server in a datacenter somewhere needs to decrypt the data to do something useful with it, after all you’re paying for compute, and homeomorphic encryption is too slow, so the work is done in unencrypted data.
There it is. Your data in plain text in RAM.
TLS will protect your data in transit, but it can’t protect you against a compromised recipient.
They could just do this to the specific servers they want, at specific times.
Just like wiretapping didn’t mean listening to every phone, and every conversation.
