For the most part, software does not exist in a vacuum. If there is a serious bug, or much improved feature, in a library you depend on, what do you do? Most likely you'll try to upgrade the library. Same deal for the compiler, it&#x27

I believe there are many top level chess masters that consider chess an art. Same for programmers, to many of the best, it is an art form or at least a craft that they take very seriously. And many would disagree that programming is solved.

Good to point out the difference between taxes and other tariffs, but I have a hard time understanding why you have to call what I said "wrong"? What you went to explain in detail is exactly what I alluded to, that also matches th

The prices of so many things have gone down with times due to increased efficiencies. Why not electricity? If solar PV is cheaper than fossils, I would, naive as I am, expect prices to go down. (I acknowledge fossils have been going up for

FTR and for the inevitable downvoters, I am not a fan of fossil energy. I am merely a fan of well presented arguments, and downvotes aren't that.

What I am saying is that those spot prices may not represent all of the reneweables' marginal costs. Question is, will the end consumer prices ever go down, and by how much?
7.
by jstimpfle 12d ago
I was under the impression that the taxes are going into infrastructure and grants for renewable energies, meaning those energy prices are maybe way higher than advertised. Funny thing is we are constantly being told how cheap reneweables a

This is interesting, but now explain why Germany has both the highest electricity prices in Europe as well as a relatively high CO2 footprint from electricity? Germany is buying not only nuclear but also coal energy from neighbouring countr

Not following Omarchy, not even sure what it is trying to be compared to existing distros (other than an incredibly hyped up product). Not hating on DHH. But hasn't he become famous for developing a web framework (20 years ago), rather

I actually explained well enough why this requires to a large degree a competent developer to judge.

Good, you achieved a 10% speedup for a particular workload that some users said they care about. But how do you find out that was really the feature that should have been built next? How do you prevent adding badly factored code? How to mak

How do you measure them if you don't understand what you're doing? A shitty benchmark or small test suite is not how solid software gets made.

How do you judge "better" if you don't understand the LLM output?

by jstimpfle 28d ago
Yes -- I can see good use for runtimes. For example, compiler can autogenerate good runtime error messages. Thinking about it, debuggers make use of reflection. Debuginfo formats have some kind of reflection built in.
17.
by jstimpfle 28d ago
Reflection is a joke. De/serializing arbitrary C++ structs is ill-defined. When you need serialization, even lots of it (e.g. silly JSON), I think you're better off writing your own framework where you can be clear about data form

I challenge you to find one random person making that claim and to present it with a straight face. What kind of ghosts are you fighting?

by jstimpfle 1mo ago
Who uses Ada95 or whatever? You are fighting strawmans, nobody has made the claims you imply. My personal opinion is just that low-level access is essential to make interesting and performant programs. Object-type fluff doesn't help wi

Casting integers to pointers is implementation-defined as far as I know. Even if weren't, I'm not convinced that you have to interpret C's address space as flat just because it is finite or because pointers are representable

Mind you, the "you can use this other way as you see fit" idea often isn't practical (like combining GC'ed and non-GC'ed parts). You generally want a whole codebase to be structured according to shared idioms. Other

by jstimpfle 1mo ago
It isn't actually that flat in the spec, though modern machines' address spaces are. So in a sense it is merely an accident of a specific implementation that you can smash stacks.

by jstimpfle 1mo ago
But I assume that both on compiler and on machine, the evaluation is still conforming to the semantics of the C abstract machine?

by jstimpfle 1mo ago
So do you want to "rewrite" some C code in C++ to think you made a point? I think you should do C# or Java. What about you do xxHash? Should be quite basic, not a lot of complicated structures. https://github.com/C

You are again misreading even the most clearly put statement. Compared to e.g. Javascript, C is "closer" to the hardware, gives you "more control" of it. It would be completely ridiculous to deny this fact. And if you mo

Many other languages only have one compiler available to start with. Each additional compiler supported by a project means variance in functionality and thus additional work for the project. That work could make the codebase more robust. Or

_You_ do that. All the time. And then you fight these strawmans.

Are you saying there is cache thrashing because callers often sercice rheid own requests themselves? If you don't want to service requests in the same thread, doesnt it mean you have to spend entire core(s) for running the kernel?

Actually, not half a dozen, more like hundreds if you count all the tiny ad-hoc stuff too (many of them similar or the same).
