Re: complex numbers in clojure

I'll just add that core matrix complex doesn't prevent you from using rationals, as most of the math happens on real/imaginary matrix pairs. However, any time you try to return a scalar value (not a matrix), it wraps the result using the alanforr library, so you'd be potentially restricted there,

Right behavior of core/bean

Re: how to speedup lein uberjar?

Thanks Asim for this suggestion. I wanted to do it but did not have the bandwidth to explore how to do it.. I am new to spark.. I usually do repl-driven dev for local apps... Have you done repl-driven using spark and clojure? do you have pointers as to how to do it.. I can explore if you tell me

Re: how to speedup lein uberjar?

Hi Sunil, Here is something to think about. Can you use the REPL for your workflow instead? If the changes are all in the Spark driver code you can run the driver inside the REPL and then test out the changes in the REPL. Once you have something that works you can save that and deploy an

Re: Right behavior of core/bean

Seems buggy to me. Most likely, bean needs to do more work in implementation. Same behavior in 1.7 and 1.8. In 1.6, the into call actually throws an exception as the proxy doesn't implement iterator(). Ticket welcome... On Monday, November 2, 2015 at 1:26:32 PM UTC-6, Sean Corfield wrote: >

Re: If a Java function seems to never return, how do I test?

It is possible to rebind System.out to something else inside Java, so the library could be redirecting it from your view. Not saying that's happening, but it's possible. If you you can connect with a debugger, you can set breakpoints based on any thrown exception. On Monday, November 2, 2015

Re: If a Java function seems to never return, how do I test?

Now there is a new error. Somehow, when the exception happens in our Java library, even though we, in theory, write to System.out.println(), I never see the Exception in the logs. All I can think is that somewhere in the Java library there is an exception that we catch but we forget to do

core.cache limits?

The lirs cache in core.cache looks good, but I don't follow the code for setting the limits. I'd like to use this as a node cache for virtual data structures. So I need a large, but configurable, limit. Did a web search, can't find any examples for setting the limits. Most of what I found was

Re: is there a community "best practice" for including your co-workers libraries?

You don't really need to set up a server infrastructure if you can live with hacks. One way is put the JAR say in a "/lib" dir and point the :resource-paths entry in profiles.clj directly to the JAR, so "lib/my-coworker-lib.jar". The other way is http://stackoverflow.com/a/26997656 but I only

And yes, the first time you look at the details of map destructuring for optional keyword arguments in Clojure functions it can be a bit confusing, but it is such a handy idiom once you get used to it. On Monday, November 2, 2015 at 5:53:33 PM UTC-6, James Elliott wrote: > > If you really do

Re: core.cache limits?

It is the parameter list that threw me off: [base & {:keys [s-history-limit q-history-limit] :or {s-history-limit 32 q-history-limit 32}}] That's more destructuring than I've ever seen. -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to

OK, after a bit of digging into destructuring, I THINK I just pass the argument {s-history-limit 1000 q-history-limit 1000} or perhaps {:s-history-limit 1000 :q-history-limit 1000}. -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this

Solved by repl. (f :s-history-limit 1000 q-history-limit 1000) is what I want. (I'm finding clojure to be a rich language.) -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this group, send email to clojure@googlegroups.com Note that

hi, ignorant question from me: F#/dotnet has 'mbrace' which lets you, apparently, *super* easily spawn things off to a cluster (cloud based). Instead of doing async { /*worker code*/ }; you do cloud { /*worker code*/ }; and all the management of getting it sent to the cloud, run, and back is

If you really do want to set both parameters, you need both to be keywords, i.e: (f :s-history-limit 1000 :q-history-limit 1000) That may have just been a typo in your posting, but I wanted to be sure it was not also in your code. -James On Monday, November 2, 2015 at 5:11:03 PM UTC-6,
