Bit of a technical post for my own reference, about visualization and scripting in clojure.

Michael>> Which areas in Clojure should a would-be Clojure programmer concentrate on in your opinion?
Rich>> If you are coming from an OO background, the most fundamental thing is to concentrate on programming with values. Don't try to replicate your mutable objects, you need them far less than you might think.
Michael>> Do you think this …
…transitioned to a hybrid approach with Ruby apps intermingling with Scala and Clojure apps. I think some of their idea of what is idiomatic Rails and how to operate Ruby are not exactly on center. But, their approach to the problem of a large Rails app is right on: break it up into "micro-services" that, if you don't like the code, you can rewrite quickly if necessary.
Lest you fear this is yet another " Rails doesn't scale!" deck, they do make a key …
The next step was to see how these messages would interact with Clojure and clojure-protobuf which conveniently includes a Leiningen task for running both the Protocol Buffer compiler protoc and javac .. Fortunately, there's already a few options and I tried out
I added the dependency to my project.clj:
At the time, the protobuf library expected your .proto files to be placed in a ./proto …

The R code to plot the confusion matrix is as follows:
caret package which includes a function to build the confusion matrix from observations directly and also provides some useful summary statistics. I'm going to hack on our classifier's Clojure code a little more and will be sure to post again with the findings!also suggested using the
as of Light Table 0.2.0, the entire thing is now built on top of ClojureScript and the only Clojure left in the system is used for evaling Clojure. With the help of the Node-Webkit…
for-comprehensions; I guess I've read enough about them in Clojure now that they make sense in Scala. It's worth noting that Scala's for-comprehensions feel simpler than Clojure's.
Self-type annotations; I've seen this all over in Scala code and didn't quite understand what was going on. It sure does have an odd name.
And some things are still confusing to me:
Type bounds, variance; when will I need these?
Linearization of object hierarchies; rules, …
