There isn’t enough data to make that claim with any confidence yet. It could just easily be the start of a spiral into an Argentina style socialist nightmare. The ability to vote for the party offering you a raise may be too dangerous. Ther

I’ve used Rust extensively the last couple years. I understand that. A lot of what people do with reflection in Go could be done more efficiently with code generation - but more easily with reflection. I’m sure the same is true in Rust, to

Are you saying there aren’t any legitimate uses for runtime reflection? Because I think Java and .Net, even Go have proved that wrong over the years. This seems like a valuable library. It’s impressive that it can be so powerful in a compil

Graham Hancock is a journalist, not a scientist. He doesn't pretend to be otherwise. He's likely wrong about most of his theories. But he's challenging accepted ideas in a field where accepted ideas are frequently overturned.

C++ is a great real world example of ignoring the advice "if you find yourself in a hole, stop digging". They have this problem with complexity and the only strategy they have to tackle it is by adding more complexity. Maybe they&

That's just factually incorrect. The largest pre-colonization city in the US was a piddling 20,000. Even Uruk in ancient Mesopatmia, was more than twice that size over 5000 years ago. Presumably you're referring to Tenochtitlan w

It's also a searing indictment of Linux. I get less than half the battery life on my Alienware AMD laptop under Linux than under Windows. I don't know what Linux is doing wrong here, but it is not energy efficient.

Because practice is not the same as theory. It's both faster and slower than C, depending on the program, but overall slower. The answer to why is deeply complex and varies on a case-by-case basis. Rust is far more complex than C, so s

It's not a big deal. People give up more than 1% in suboptimal compiler flags alone. People give up far more than that by using unoptimized or lightly optimized code. People give up more than that by being too lazy to use profile guide

Wow! Probably similar numbers for concrete. It's exponential growth. The thing about exponential growth is it can't continue for too long. As observers of Moore's Law will understand, eventually you run out of resources or in

I just want to add to your explanation, that even in the absence of hard paging from disk, you can have soft page faults where the kernel modifies the page table entries or assigns a memory page, or copies a copy on write page, etc. In addi

I always thought of myself as quite left of center. Now I find myself on the right, and I don't understand if I became more conservative as I got older, or if the center moved past me to the left.

I agree with you. I also thought we were screwed in the West precisely because we couldn't do the kind of strict lockdowns China initially did, which worked so well for them. Things have changed. I would say because countries don'

It's not as simple as NIH. Using cgo means you have to build and link external dependencies in another language. Compared to Go, this makes it quite a bit more difficult to build and distribute than a single binary. But I think the big

I hate SPAs. I would never do another SPA again if it were up to me. It just adds too much mental context switching and overhead. I can develop fully server-side apps that are lighter, run faster, and at least 20% less development effort (I

I choose boring happily over being dead. I don't think I would be willing to give my life to defend a country unless against a terrible evil like the Nazis.

Evil is a pretty strong word to toss around like that. The Nazis were evil. How is the West evil? Western countries do a number of bad things, but they're not evil.

It has complex failure modes though, unless you're not at all concerned about what happens if the program crashes, power goes out, file gets corrupted, etc. It's surprisingly difficult to write something that stores changing data
