Re: interp2 for Clojure

These are both fantastic. It has been 25 years since I had a serious math class (no Stats either - Set Theory, Category Theory), so this has taken me a few afternoons to wrap my head around. Spline? Cubic? Bicubic? RBF? Shephard? And that's just interpolation. Its weird that the Commons Math

interp2 for Clojure

Greetings. A current project I am working on needs to run a Bilinear Interpolation. R and Python (SciPy) have functions for this: interp2. I think this is just a fancy name for particular matrix multiplication. But I'm not really sure. Can I cobble this together in core.matrix? Incanter?

re-frame and material-ui

Greetings, I am pretty new to ClojureScript and re-frame but it all feels right. I am trying to replicate a small React project and show just how much more awesome it will be. But it is using material-ui. I'm sure this is a normal thing. There was even a library a few years ago integrating it

Re: Am I being stupid regarding how much memory I use?

Did you pull all 4 million at once? Are you doing a huge sorting operation over millions of records in memory? Then yes, you are going to use a lot of memory. There aren't many ways around it. Eclipse Collections (and others) have smaller collections than java.util. Maybe they make a

Here's another crazy question... How would I use this from Java? Seriously though. I might be forced to use Java on my next project but I really like Yesql over MyBatis (the closest thing in Java Land). Has anyone done it before and can show a small example? I don't want to give up my .sql

Re: [ANN] New core.async release

The most interesting thing I've learned from this release is just how lenient old releases were in the face of erroneous code, of which I appear to have had rather a lot. :) That said, I have found at least one behavior I'm not able to understand. This works perfectly with the new core.async:

core.async: closing a mix only when all inputs have emptied

Howdy -- Trying to use core.async's mix facility, one difficulty I've run into is the lack of a means to close the output channel only after al inputs have been exhausted. In the interim, I've ended up using the below instead -- which lacks some of the facilities provided by the mix interface

What does Clojure get from Java 8?

I had read that the Clojure team was prepping the build to work on the new JDK8 and it got me to thinking - what does Clojure get from Java 8? Will it be using some of the new features or does the compiler just need to be ready for changes in the JDK so compilation passes? Clojure already has
