I spent years not upgrading because when I'm in my car asking my phone to navigate somewhere, Gemini likes to say "As a large language model I can't navigate anywhere. Try using a map application on your mobile device."

Matching decomp would require the same compiler and flags as the original game, right? How is that determined?

I will try to remember him for his far too relatable Dilbert comics about corporate office life, and not his, uhm, later work. One of my favorite strips was Dilbert in the 90s only being given a 286 PC for 3D rendering work, with the boss s

I once saw a high resolution CPU graph of a video playing in Safari. It was completely dead except for a blip every 1/30th of a second. Incredible discipline. The Chrome graph in comparison was a mess.

I'm Norwegian and concluded that she meant when ordering, such as for a choice of potatoes or pasta. This makes sense since the context is translation for tourism. Otherwise, the normal, casual way would be "kan du sende potetene?

Good call. O(N^2) is the worst time complexity because it's fast enough to be instantaneous in all your testing, but slow enough to explode in prod. I've seen it several times before, and it's exactly what happened here.

My bad. I had been reading about how there's a frustration in the community that allistic people refuse to explain why such statements are wrong, and instead just repeat "you know what you did!" to people who genuinely don&#x

The article starts off saying that if you want people with real full stack experience, from kernel to UX, you need to grow it. It goes on to say that it's hard to find and develop expertise for low level software like hypervisors. What

It feels like we're back in 1900 when anyone's clever idea (and implementation) can give huge performance improvements, such as Ford's assembly line and Taylor's scientific management of optimizing shovel sizes for coal.

I worked on this project for a week during the FB team matching process. I had previous Haskell experience, but what struck me was how irrelevant that was. To their immense credit, they had managed to use Haskell to write an entirely entrep

Tbh if you've never done either, I can absolutely see why getting on and riding a machine 1000x your size is a bigger deal than seeing various animals from a distance.
