Re: Clojurecademy: Learning Clojure Made Easy

Concerns over licensing and user agreements and logins aside... REALLY COOL WORK! I haven't dug deeply yet, but it seems you've built a framework for building Clojure based courses here, not just a fixed set of curriculum. And to this effort, bravo! I hope to see this become a very useful tool

Re: Clojure for big data

Hi Ray > This is partly prompted by the lack of activity on the Github repos. Maybe you have higher standards here than I do... last commits on Flambo and Sparkling were 3 and 2 months ago, respectively. That doesn't raise any alarm bells for me personally. Moreover, looking at the contributor

Re: Clojure for big data

Thanks for the helpful information Christopher. I'll have to look at Powderkeg. The AOT issue is a big one. Being able to launch things from the REPL is huge. That's actually one of the many advantages of Onyx over Storm (if you're looking at the streaming side of things). Towards the end of my us

Re: Port graphs: What would Rich Hickey do?

Do you need to be able to attach data to specific edges instances? Or would it be sufficient to be able to have different types of edges, and be able to associate data with those abstract edge types? If the latter, you might want to look at Datomic (also authored by Rich Hickey), DataScript (a

nd "chain[ing] anything to anything", you're right; this is a major benefit over traditional SQL. Attribute are fundamentally polymorphic, which can be super helpful with tricky modelling problems. Chris On Thu, Jan 4, 2018 at 10:48 AM, Ben Kovitz wrote: > On Tuesday, January

A Wize One once said > Closures are the poor man's objects It's easy to build "object-like" things in clojure. Just create a map pointing to whatever you like, including stateful things, like atoms. Then write functions which take that map and do stuff with it. Clojure's Records and Protocols

Re: Simulations in Clojure/Clojurescript

I'll second looking at Vega and Vega-lite. Grammar of graphics is wonderful. With regards to simulation on Cljs, keep in mind that JS is limited in numerical precision relative to the JVM, and this can be important in some simulation contexts. Just make sure you are aware of the probabilistic impl

Re: group rows on basis of value in a column in CSV with clojure

You may want to take a look at my library semantic-csv, which lets you cast rows as maps instead of vectors, so that you can group-by a column name instead of a positional index. https://github.com/metasoarous/semantic-csv On Saturday, July 7, 2018 at 11:07:50 PM UTC-7, Varun J.P wrote: > > Hi
