Very weird that the "generative model" article focuses so much on classification

ok I was confused, guess I already had this
Same brain, different conversation histories per project. The memory blocks (which live in the agent) are shared across all projects. The conversation transcripts are per-project.

So you already have what Cameron described - one shared Subconscious agent across your related repos. The .letta directories in each project are just bookkeeping for "which conversations happened in this repo."

Getting around Rust's trait limitations with type-level first order logic 🔥
/// Type-level boolean trait for compile-time boolean values
pub trait TypeLevelBool {
    /// The boolean value at the type level
    const VALUE: bool;
}

/// Type-level representation of `true`
pub struct True;

/// Type-level representation of `false`
pub struct False;

impl TypeLevelBool for True {
    const VALUE: bool = true;
}

impl TypeLevelBool for False {
    const VALUE: bool = false;
}

// ============================================================================
// LOGICAL OPERATIONS
// ============================================================================

/// Type-level AND operation: A ∧ B
pub trait And<Other: TypeLevelBool> {
    type Output: TypeLevelBool;
}

impl And<True> for True {
    type Output = True;
}

impl And<False> for True {
    type Output = False;
}

impl And<True> for False {
    type Output = False;
}

impl And<False> for False {
    type Output = False;
}

So at a high-level, you write something like this
#[mathcompile_optimize]
fn my_expr(x: f64, y: f64) -> f64 {
    (x.exp() * y.exp()).ln()  // → x + y
}

Deleted my original QT. I jumped the gun on this - beating the market is nothing like a fair coin flip. This is a better way to look at it
Robert Reich post: 
"The stock portfolios of more than two dozen members of Congress outperformed the market in 2024.

This isn't due to luck or skill.

Lawmakers can use privileged information to trade stocks while they’re supposed to be working for you.

Make no mistake, it’s legalized corruption."

I thought there was something like an rng.gen_bool() for a fair coinflip in Rust. A quick search took me into this alternate reality
Rust Coinflip Explained

Rust coinflip sites have become a popular avenue for players to engage in a variety of betting game modes. Coinflip is one of the most straightforward yet thrilling options available. In Rust coinflip, participants bet their in-game skins, which hold real-world monetary value, on a simple coin toss. The appeal lies in its sheer simplicity and the high chance of doubling one’s wager. It offers an adrenaline-pumping experience each time the coin is flipped.

One of the key attractions of coinflip, and what sets it apart from other types of betting games, is the low house edge. Most gambling activities are designed with an inherent advantage to the service provider. Rust gambling sites tend to offer a comparatively lower house edge for coinflip games. This means that players have a better chance of winning in the long run. It making it a more appealing option for those looking to gamble their Rust items.Lots of gambling sites with names incorporating "Rust" for some reason

T. Rex, Electric Warrior. It's from '71, still slaps. Sadly they weren't around long - Marc Bolan died in a car crash in 77. Album art by Hipgnosis, check out the Squaring the Circle documentary on Netflix to learn more about them.

Fiery Furnaces, I'm Going Away. FF is the Friedberger siblings Eleanor (vocals) and Matthew (keys and some vocals). FF has some unusual stuff; this album is maybe the least so (but Drive to Dallas gives a hint of that). Some other albums are synth-heavy, or for more rock check out the live Remember

Ugly, by Screaming Females. All of their stuff is great, I just picked this one because it has the Steve Albini treatment. Marissa Paternoster on (excellent distorted) guitar and vocals (clean + vibrato, no screaming). Sadly they recently broke up, but I think she has some solo stuff in the works

High Visceral, Pts. 1 & 2 by Psychedelic Porn Crumpets. The Porn Crumpets are from Perth. "Psychedelic" is dead-on, but AFAICT "Porn" is just to get boomers tut-tutting. Vocals have a Tame Impala-like "faraway" quality, but it's much more rock than TI, with fuzz guitars and layered effects. Trippy.

A Man Alive, from Thao & the Get Down Stay Down. They're listed as "alternative folk", but maybe more descriptive that this album was a collaboration with Merrill Garbus from tUnE-yArDs. Definitely some influence from her, but I like the direction Thao takes things that makes it different
