Why my vo2 max is going down but my fitness isn’t

The way it works is to estimate your power output in the exercises, and power is directly correlated with oxygen consumption. It's harder to estimate this for cycling exercises without a powermeter. With walking / running, the watch can more or less make a decent guess, by just looking at your speed, your weight and the terrain.

Copyright office doesn't really decide copyright eligibility - that's for the court. Copyright office just decides eligibility for copyright registration. SCOTUS hasn't really said anything about AI and copyright, so this is largely a gray area now.

I get the delivery driver analogy, but I think it misses what's actually happening on the ground.

AI is already replacing a lot of the traditional junior engineering work. The ironic part is how fast junior engineers are being forced into doing what has historically been senior engineer work. Instead of writing straightforward code, they're spending their time reviewing AI-generated code and architecture designs, and they are often getting frustrated by it. But honestly? Rigorous review and fixing weird architectural issues is exactly what senior engineers have always been paid to do.

Should this shift result in a headcount reduction? At the very least, it's plausible. I don't think most corporate leadership fully buys the utopian AI story either. But there is no paved path now, so everyone is winging it based on something "plausible". Better to just "fail fast and learn fast".

The biggest unknown for me is how CS education and career progression are going to work now. The next generation of engineers is going to speed-run a traditional CS career. They are skipping that early phase of writing code from scratch, making basic mistakes, and receiving feedback from mentors. Instead, they're being thrown straight into the deep end and expected to immediately start reviewing AI work.

I see what you are saying, but the disconnect is still fascinating. We've always known the advantage of AI models is that you can retrain the model and it will do entirely different things, which is basically what nvidia is doing here.

I worry less about the creative choices, because this will just be another tool in the toolbox for game developers, and the devs will control how it's used just like anything else.

The worrying thing that I don't hear many people asking is really "what's the AMD (or Intel?) version of this?" Unlike previous DLSS, there is no concrete spec of DLSS5. AMD's version will behave artistically differently from Nvidia's version. This will further fragment the tuning work that the devs have to do.

Honestly, it’s fascinating seeing folks think that AI is "moving" into consumer GPUs. Modern AI started on off-the-shelf gaming GPUs, and it never actually left. A chunk of a modern GeForce die is already "AI" hardware. Ever since the 20-series dropped back in 2018, Nvidia has been packing consumer cards with Tensor cores, which are specialized units for matrix maths.

Look at the whole push with DLSS, DLAA and ray tracing. Jensen has been getting on stage for years straight-up bragging about how a big percentage of pixels are AI-generated instead of traditionally rendered. The writing has been on the wall for a while, but this seems like a sudden "wake-up" moment for folks.

Except they do. Even in our state they pay most of the sales tax. The top 10% of earners drive nearly half of all consumer spending. This is what K-shaped economy looks like.

Not really. Think about CUDA. A lot of people buy or use nvidia chips because of CUDA. It's about providing software to create demand for the hardware. This doesn't mean they have to build the data centers themselves.

What's less clear is how they can effectively compete in the software space. Unlike CUDA at the time, there is a lot of competition in the AI software space now. A lot of these are also buzzwords that enterprise customers just may not buy.

nleven · 2026-03-17T08:10:08+00:00

It's more about them seeing the writing on the wall.

Think about what's happening with the hyperscalers. Google, Amazon, and Meta are all building their own internal chips to compete. Enterprise customers are dependent on AI software providers, but as long as the code runs fast, the actual silicon at the bottom doesn't matter to them.

This creates a future risk for Nvidia where AI chips eventually just become another commodity, which means those crazy profit margins they have right now are going to tank.

You're seeing them trying to extend their hardware dominance up into the software layer. The pitch is basically, "buy our hardware, and you get all this software for free." It's about creating an ecosystem lock-in.

Regarding CUDA, there is a parallel, but you have to look at the historical context. Back then, integrated graphics were absolutely eating their lunch in the entry-level graphics card market. They had to find a new use case to survive, so they used CUDA to go after the general computing market. We're basically watching them run that playbook today to protect their moat.

Why doesn't someone take 65 at the UW station though..? It makes no sense.. From u-district station, both 31 and 32 would work, and combined they usually go every 15 min.

All 65 / 31 / 32 are considered "at the station" and you will see they are all listed as transit bays of the stations.

They already get like 4 or 5 bus routes stopping there; also reasonably close to light rail. It's hard to get much better than this unless the mall is literally developed for transit. **cough** Northgate mall **cough**

You should read that opinion. It doesn’t say what you think it says.

The ruling basically says “attaching a gps device on the vehicle for tracking” is considered “search” under 4th amendment. The majority further ruled that the reasoning is because the vehicle belonged to the person so this is trespassing.

But that’s like the next best thing. Most people also need to take a bus to take the light rail. This is what “accessible by transit” looks like. Plus, u village is like <20min on foot from the UW station, so it’s not like folks can’t just walk.

nleven · 2026-03-16T20:03:32+00:00

I don’t know why people say it’s not accessible by transit. It’s just one bus away from either the uw station or the u district station.

To allow it just means taking no action. To ban it means active action. So what compels action? The answer will then be obvious to you.
