Lemme try that game. Would you rather have 2 PS5 Pro plus 3 years of PSPlus Premium, or an NVIDIA 4090?
Oh, wait, that's not how it works?

I am looking at the possibility that my PC (13900K) might be a million times as fast as home computers from 40 years ago.
Which would mean that my PC can do as much processing in 20 minutes as such an old computer could have done since its original release.
Even though I'm deeply familiar with the performance differences, my mind is still blown.

I don't know whether I should be frustrated or amazed that I get better internet speeds by tethering to my LTE phone than through our home's DSL line.
Ultimately, our DSL is fast enough for most use cases, though some larger downloads can easily take all night.

Awesome article. I've seen Linux outperform Windows in Blender and PovRay rendering. It's still quite behind in video editing, though, e.g. DaVinci Resolve.
What frustrates me the most with Linux is the sad state of NVIDIA drivers. One day they crash at boot. Another day they're full of glitches. Another day they degrade terminal performance to the point of being unusable. Let's not talk about Wayland. I've had to downgrade to my Intel iGPU as a result.

I'm wondering whether there's a chance of writing 80s-style demos for some RISC-V hardware. Is there some hardware that's documented enough to use directly from assembly? I mostly care about graphics, sound, inputs. If not, is there a runtime, or some OS / libraries that would provide an acceptable boilerplate? Is there a decent assembler out there (i.e. that's meant to be used by hand, instead of being fed the output of a compiler)?

Thinking a bit outside the box: if you're looking for a high pixel count and the ability to keep some Canon EF glass, a Fuji GFX100S (or 100SII) with a good active EF-GF adapter might fit the bill. EF 85/1.2 covers GF with some swirly bokeh, and the FF crop still has ~60MP, same as Q3 or A7R4. M glass is also an option. But then that Fuji GF glass is addictive. Please help me stay away from that 55/1.7.

Me, 3 days ago: my code is perfectly optimized, there can't be any way to make it faster.
Me, yesterday, spending hours at the keyboard: I feel there's a way to make that code faster, but I can't figure it out.
Me, today, during lunch, far from the keyboard, and after 2 glasses of wine: that's it, I found how to make that code faster.
I'll test it when I'm back at the keyboard. Bonus points: the optimization should also enable a simplification.
