Local Qwen isn't a worse Opus, it's a different tool

We've all heard people say that Qwen is near-Opus level, but I have receipts and am here to be transparent with you.

Alright, future engineers!
**Product Rule:** Differentiates the product of two functions.
Formula: `(uv)' = u'v + uv'`
Pro-Tip: It's NOT just `u'v'`! Each function gets a turn being differentiated while the other stays put.

**Chain Rule:** Differentiates composite functions (function within a function).
Ex: `d/dx sin(x^2) = cos(x^2) * 2x`.
Pro-Tip: Always differentiate outside in!

The **Chain Rule** differentiates a function inside another (a composite function).
Ex: `d/dx f(g(x)) = f'(g(x)) * g'(x)`
Pro-Tip: Differentiate the *outside*, then multiply by the derivative of the *inside*! Think 'onion layers.'

The **Product Rule** differentiates a product of two functions.
Formula: `(fg)' = f'g + fg'`
Pro-Tip: 'First D Second + Second D First' is a classic mnemonic!

And because of that key characteristic--acquiring things makes people who hoard feel good whilst people engaging in OCD behaviours feel horrible--#HoardingDisorder is no longer #classified as a type or manifestation(?) of #OCD in the DSM.

Hoarding Disorder is a separate, specific condition with specific #diagnostic #criteria in the more recent editon(s) of the #DSM.

If the only thing you know about people with #HoardingDisorder is something from #RealityTV, I strongly encourage you to learn the actual reality.

I'm no expert on the #diagnostic side but my understanding of the condition and it's history in the relevant #medical #literature is that hoarding was once considered a manifestation(?) of #OCD, but over the years experts noted a key distinguishing factor for hoarding vs OCD in particular:

When people with OCD are engaging in a repetitive behaviour (eg: excessive handwashing) they feel terrible about it. They want desperately to stop *in the moment* but cannot do so.

People with hoarding disorder, OTOH, feel good, perhaps even fabulous, in the moment(s) of acquiring new things. The bad feeling only comes after and/or when trying to de-accumulate.

And a full-abstinence, AA-type approach cannot work, as people NEED to aquire things to survive: groceries don't buy themselves, after all! 😐

Chain Rule helps differentiate composite functions (function of a function). Formula: d/dx [f(g(x))] = f'(g(x)) * g'(x). Ex: d/dx [(x^2+1)^3] = 3(x^2+1)^2 * (2x). Pro-Tip: Always think Outside-Inside! Differentiate the outer function first, then multiply by the inner's derivative.
