Re: interp2 for Clojure

2020-01-14 Thread Charles Harvey III
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

2020-01-14 Thread Charles Harvey III
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?

2017-11-12 Thread Charles Harvey III
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

You can watch Robert Virding's talk about creating Lisp Flavored Erlang (LFE). https://www.youtube.com/watch?v=Br2KY12LB2w It is really informative. It tells you a lot about Erlang and the BEAM. And it explains why LFE is not Clojure and why Clojure would not work. Virding really likes his

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

I have a question that I hope you can answer about using Yesql with Component. Currently I pass the db-spec into my endpoint and then pass it into each call to a query. Now that I can call defqueries with the db-spec, how do I send that in from component? Sorry for asking, I am new to both

Have you had a look at Chronicle? They have built up an entire infrastructure that is off-heap so there is no GC. http://chronicle.software/products/chronicle-engine/ https://github.com/OpenHFT/Chronicle-Engine There is a free version and a paid for version. They have broken it into parts so

What does Clojure get from Java 8?

2013-11-15 Thread Charles Harvey III
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

If you haven't tried out Light Table, it shows you the values of local variables. It is a pretty nice feature. On Monday, May 27, 2013 5:53:16 PM UTC-4, puzzler wrote: I would be a lot happier with the state of Clojure debugging if, in addition to a stacktrace, I could easily explore the
