Nice to see this submission getting traction, especially given that the first submission got none at all. Clever of llambda to use the trailing question mark on the URL to confound PG's duplicate detection mechanism.

#12Ummm....
Following the first thing in the tutorial:
Clojure> (+3 3)
java.lang.ClassCastException: java.lang.Long cannot be cast to clojure.lang.IFn

What have I missed?

You need a space between the + and the first 3 (+ is the function you want to call).

Thanks. The tutorial didn't show that:

And when I click the tutorial's "(+3 3)" grey box, it inserts what looks like no space between the + and 3, and lo and behold, it works (6). And when I type it in now with no space (+3 3) it works too. :/

oops - sorry - I'm totally misreading it. :/
Re: Try Clojure in your browser
#16I have always been frustrated by tutorial REPLs that make me copy and paste example codes. I simply don't write them manually to CLI and I believe many people do so. Therefore maybe a link to directly paste and execute code on tutorial steps would be quite useful. Like "run this".
If you click some of the code examples in the tutorials, it will paste them into the REPL. You have to hit enter to run them though.

#17I appreciate that it works very nicely on my iPad, as far as writing lisp on a touch keyboard goes.
Re: Try Clojure in your browser
#18It's cool, but the REPL could let you do multiline stuff by detecting whether you've closed all the parentheses and quotes yet.

#19Is there a Java Applet version available? Why run it remotely when you don't need to?
Re: Try Clojure in your browser
#20I found it fun to see division results returned as fractions. Has anyone here switched from Python to Clojure for data analysis? What has been their experience?
Not recommended. Matrix multiplication is really slow, even with Incanter. I doubt you'll get very far with data analysis without multiplying a few matrices so avoid.
Slow compared to what? Numpy (or equivalent) or optimized fortran?
