I came across J/K/APL a few months ago while working my way through some project euler problems, and was intrigued, to say the least. For every elegant-looking 20 line python solution I produced, there'd be a gobsmacking 20 character J solution that ran in a tenth of the time. I've been keen to learn some basic J, and have made a few att...
I have been reading Wikipedia's article on K programming language and this is what I saw: The small size of the interpreter and compact syntax of the language makes it possible for K applications to fit entirely within the level 1 cache of the processor. I am intrigued. How is it possible to have the whole program in L1 cache? Say,...
I know all 3 are related, and I've seen quite a few answers for problems in Project Euler written in J, and a few written K. What I'm wondering is, which would you suggest learning, and where would you suggest going about getting the materials to learn it? ...
I'm writing code in C++, but I really like K/APL's array-oriented style. Does anyone know of a good set of operator overloading tricks / macros / ... to allow some K/APL -style programming in C++? Thanks! ...
Hi I'm playing a little bit with image similarity. In fact i'm playing with image retrieval system. Ideally i wanna to create some kind of image index that I can query to get similar images. My current thought is to store some kind of ImageDescriptor into index and each descriptor can have different features in it, e.g. k-mean-cluster-...
The array-language landscape, while fascinating, is confusing to no end. Is there a reason to to pick and of J or K or APL or A? None of these options seem to be open-sourced -- are there open sourced versions? I would love the expand my mind, but I remain befuddled. ...
Does anyone use K or Kdb outside financial arena? If so what have you used it for. ...
