https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/Executors.html#newFixedThreadPool(int) [service (java.util.concurrent.Executors/newFixedThreadPool 24)] that is something that should, in theory, be a queue with 24 worker threads right? "ps aux | grep java" is only showing a single thread, "top" is only showing < 100% utilization, iknstead of 2400% utilization

Are you sending it 'jobs' that take significantly longer to execute than the overhead of starting and finishing the jobs? Sending it really tiny jobs might not get you any actual parallelism

Each jobs takes 10-20 seconds to execute.

Turns out, I was mis-reading the output of TOP. On per process, it' sshowing full usage (i..e 2400%), but on the top overall usage, it's showing 99% (i.e. 2400 / 2400).

is it possible to: 1. pass an anonymous function to a macro and 2. evaluate the function at MACRO EXPANSION time in particular, I want to do: (defmacro foo [ .... ] ....) (foo (fn [x] (println (+ 1))) ...)

and I want the function evaluated at macro expansion time

you're actually passing a list to your macro ... that might require a call to eval

yeah, I have this weird situation where foo behave as follows: (foo f1 f2 data) where data is interpreted as data however, I want to parameterize foo by passing it functions f1, f2, that modify the behaviour of foo -- is this possible ?

Sounds like (def bar (partial foo f1 f2)) (bar data)

maybe i lack imagination, but i can't imagine a case where some client code would use a macro, parameterizing it with a function... So I guess you're writing a macro that itself calls a macro. In that case you would want the outer macro calling into functions that build the code rather than callinbg into macros, so you're out of the macro system as soon as you enter the outer level

in 10 (?) years since i started playing with clojure, i wrote maybe 5-10 macros and most were of the def-thing kind...thinly wrapping a function call.

then again, i had my macro abuse period earlier with common lisp =)

macros are a code smell (most of the time)

that's to say, are you really sure you want a macro? and if so, can you simplify it so that it's only a wrapper around your data orienbted or function oriented underlying system

I'm writing macros to help me generate clojure bindings to an java api

There are alot of functions to bind. I want to pass it two functions, c-name and j-name, which decides how the functions are named, for example, I want

(make-bind c-name j-name foo bar cat dog)

so I have c-name be a function (s -> (symbol (str "cu-" s))) and j-name something to append the java.jcuda.JCublas2/cublas and capitalize the symbol

but now, I want the cname and j-name to be functions rather than hard coded, because I also will be binding jcudafft, jcuda/cudnn / ...

@qqq can't you turn the macro into a function returning a map (of functions)?

During cider debugging, is there a way for it to keep refreshing local variables every step ( the l key) ?

(visually)

Guys how can I call the base method of a class on an object?

by making a class that calls the superclass' method right?

maybe I don't understand what you're asking for

https://clojuredocs.org/clojure.core/proxy-super ?

Why I can't (> #inst"2017" #inst"2018") in clojure? It works on cljs. And on clojure, I can compare inst via sort..

the fact that it works on cljs is just because javascript can do > with Dates and cljs's > delegates to javascript's >

clojure's > is defined only in terms of numbers

the fact that it works in cljs is an accident of the implementation

I don't remember if #inst in Cljs emits js/Date or goog.date.DateTime or UtcDateTime, if latter, it shouldn't be comparable by default, but if cljs-time.extend ns is loaded, that will extend IComparable to DateTime and UtcDateTime

#inst creates JS Date, so cljs-date.extend won't affect that

http://www.jcuda.org/jcuda/jcublas/doc/jcuda/jcublas/JCublas2.html#cublasSgemm(jcuda.jcublas.cublasHandle, int, int, int, int, int, jcuda.Pointer, jcuda.Pointer, int, jcuda.Pointer, int, jcuda.Pointer, jcuda.Pointer, int) is there a way to call 'resolve' or some other function, and get taht function as a result ?

i.e. I want something that will take "jcuda.jcublas.JCublas2/cublasSgemm", and return that function

Hm, could somebody explain me the difference between merge and into? does the latter have side effects?

nope, apparently not

into supports a transducer…

@qqq no, java methods are not first class in clojure

@synthomat merge is only for maps, into works for any collection

you could do that via reflection if you wanted to but it doesn't sound like a particularly good idea

@juhoteperi hmm, but merge does merge vectors as well. kind of

but yeah, merge source calls the parameter & maps

@bronsa: so the only three ways to get a java method are: 1. type it out literally in clojure code 2. have a macro generate it at macro expansion time 3. get it via reflection ?

yes, 1&2 are equivalent, I dont know how else you'd expect to do it

"either statically(1,2) or programmatically(3)" make a total set

lol, it has been said that genius is rephrasing the question so the answer is obvious
