Maybe this is one of those things like cold reading. IMO, the text may be seen as a piece of advertising for a fictional "de-programming" (like they call it) treatment from a cult. However, it's written for an abstract genera

I've just spent the last 30min-1h looking this up. I think I might have a form of this... Mostly, I can't really picture stuff. I thought that was just everyone. Gotta find out more about this!

He is mostly talking about computational linear algebra problems of a large scale type due to large matrices: the "computational intensity" comes from having really large matrices (kxk for k = 100's, 1 000's, 10 000&#x27

With Newton's method, you'll be solving Hx=g (H = hessian of f, g = gradient of f) at each iteration. For large number of variables N, building H is of order N^2 and solving Hx = g is of order N^3 with an usual solver. N^2 and N^3

Directly, I believe this has more to do with people interested in the language seeing it being used in actual projects. Indirectly (a lot indirectly), sure. Maybe the software should perform better or maybe have fewer bugs because programmi

> In my view, because pi crops up unavoidably in math, if you concoct a "unit" to get rid of pi in one place, it will simply crop up somewhere else, perhaps in a denominator. That doesn't mean you shouldn't try to put

The major motivation for radians is arc length parametrization, really. Meaning that in a circle of radius 1 unit (in whatever measurement unit you've chosen), an arc formed by a k-rad angle measures k units. There is an intentional co

> performance tends to be a major objective My comment is about the thinking behind making this decision, C++ or not. It wasn't "is it speculative that GC will add a cost?" or something like that. I wonder how much of the

I wonder how much of (2) is speculative and how much of it is a real need in actual projects.

For numerical and scientific (high performance) jobs, possibly not that much harder than C++. For other jobs, I doubt it and would stick to C++. The issue is that, for example, you might be getting people with poor software engineering trai

Where could one go to read more about the mathematics behind the format, its compression techniques, etc? I remember reading that jpeg 2000 is based on wavelets. Is this the case for jpeg xl?

This, I believe, touches upon the accidental versus essential complexity theme. I believe people, in general, agree C is too simple of a programming language to actually deal with all the essential complexity of modern software development

One of the thing that isn't obvious to me that seems to be for many people is the decision to maximize expected value instead of best worst case scenario. In this situation, given how exceptional the 100%1M vs. 50%50M situation is and

The investor's situation, I believe, is very much different from the common person's. The investor put him or herself in the position of doing tons and tons of financial transactions and investments, etc, like that. He or she put

I think I get it, but I'm not so sure I'm convinced. Those examples, however, don't resonate with me (don't have a car, nor a license to drive one; nor I own a house; I've been inside an airplane only once). However

I suspected that much (that it was an analogy for some kind of actual situation). But what situation? How is it that a person's life has many of these chances in large enough volumes to make expected values worth it?

I wonder how relevant operator overloading can be without things like RAII and move semantics (thinking in comparison to C++), or without some kind of managed environment. Would this be useful only for simpler and smaller objects? I'm

About drafts... Iirc, the last draft before final publication is free and it's just as good. As another user replied, there is more going on in the post than what is specified, guaranteed, etc, by the standard. The practice of C progra

Right, but is he relying on the standard (the C language specification is an ISO standard, btw) behavior guaranteed by the language? Or is it talking about some implementation specific behavior that also happens to fall into the name of fop

Yep... The "slightly better C" seems pretty universal as far as I've seen. A lot of people just want that it seems. It's not clear what that would look like though. It's a shame. Have you seen Terra? http:/&#x
