One example. Not a very important one, but illustrative. https://discourse.julialang.org/t/why-no-base-iterators-map/... The "bubble effect" here was assumption that everyone has internet access and dep

I think this is correct. My understanding of the two-language problem was probably not the same as the one they claimed to solve. More likely they meant: write slow code in python and then optimize inner loops with c. Anyways, I'm gl

I'm a Julia user who has also given up as a Julia community member. The bubble is real. I found too often when I wanted to do something outside of that bubble and asked for help, I got unhelpful advice which amounted to "why do

Right. It used to be referenced on the front page of julialang.org Seems they don't really use that in the sale pitch anymore. Maybe that proves my point. It's easy to find references to julia claiming to solve the two-languag

Julia claims to "solve the two language problem". i.e. prototype in python, rewrite in c++. The two language problem is not solved with Julia if you can't effectively generate binaries.

Anyone know what the "select" cryptocurrencies are? The focus on Bitcoin's lack of intrinsic value and energy use is really getting boring. I read Hacker News comments for more information on a story. How about some of that f

There is a fairly nuanced difference that doesn't really matter much unless you are a mathematician. Essentially in GA you'd do your differential geometry assuming a sort of ambient background space. In regular differential geom

Don't paint us all with the same brush please. Some of us are totally sufferable.

You want to pick an algebra that fits your problem. Here's an example of a high performance GA lib targeting specific hardware. https://github.com/jeremyong/klein Also you can use matrices to do calculations. Pau

This book is quite good. Suggesting we follow the historical trend where advances in physics almost always reduce the number of magic numbers in the model. https://www.amazon.com/Mathematical-Reality-Space-Time-Illus...

I've come to see it more as the inverse of a division operator. Like a quaternion can be defined as the ratio of two vectors q = a/b. then q b = a and q c will rotate c the same amount as needed to take b into a. dual quaternio

Memory layout. You can do a hacky "cast" from a homegeneous 4-vector to a ideal 3-vector for free. Same pointer.

https://brillouinenergy.com These guys seem to have figured it out. Seems the problem with replicating cold fusion is that what most researchers do degrades the "lattice" that enables the reaction. So even if you do m
