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.…

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 mor…

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 …

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…

By the way... which font is being used in the readme screenshot? https://github.com/helix-editor/helix/blob/master/screenshot...

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 shou…

> Very sincerely, you must read just about zero tech news. Not 0, but really not much, that is true. I remember the shutdown of google reader. I tried it once, but let go of it bef…

Super sincere question. > Google's reputation for not supporting things long term I didn't know Google had such a reputation. I mostly use drive and gmail, so it was fine to me. Do…

> 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 …

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…

I see it in a lot of matlab code as well.

> 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 some…

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…

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 f…

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 …

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 …

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 transactio…

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 ins…

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 volum…

> your life will have plenty of such games What are you talking about? Which life will have plenty of such games? In what way is that true?

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 th…

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, gua…
