Hi Wolodja, It's useful to note that you can use the currently preferred fixed version specifiers and still have your dependencies and the top-level project depend on multiple versions of a library (the common case is multiple versions of Clojure specified as dependencies). Also, you can specify

Re: Java interop: "Can't call public method of non-public class"

I think not. But upgrading to clojure 1.5 will do. On Friday, March 1, 2013 1:20:57 PM UTC+4, Marko Topolnik wrote: > > I'd say it's a bug. You are invoking a public class's method, which > happens to be inherited from a package-private class. Clojure's reflective > code accesses the superclass

Re: Clojure 1.5 print-table, org-mode babel, and org-mode HTML gen

This is a very helpful example. Along similar lines, I was thinking it would be cool to have a document of 4clojure problems/solutions/tests. I haven't used tangle/weave yet, which would be pretty useful for that. I think it would be a great learning resource to create an org-based book of "bes

Re: how to get SHA1 of a string?

Glad Larry has working code now... As I mentioned before in this thread, I'm working on this functional interface for the message-digesting/secure-hashing, and this whole discussion reads like a use case for the "why?" ;-) It "proofs" to me that there may be real value in a more user-friendly a

Re: how to get SHA1 of a string?

Frank, Any idea when you might release your code in a stable form? I am using this code at work so I am nervous about using code that is still marked SNAPSHOT. Lein reminds me not to use a SNAPSHOT: Could not find metadata org.clojars.franks42:clj.security.message- digest:0.1.0-SNAPSHOT/maven-met

Re: how to get SHA1 of a string?

If your code is for production… do not use my code! It's pretty much written over the weekend and it's "security code", meaning that it deserves much more scrutiny than "ordinary" code. As mentioned in the readme, it's more an "educational exercise", although it was good to see you struggling a

how do I find an IO exception triggering retries in clj-http?

So, thanks to Michael Klishin, Aaron Cohen, Frank Siebenlist and Craig Brozefsky I am now able to correctly ping the Omniture API. But I am getting a strange behavior from the clj-http library. It makes 4 calls to the API server, even though the first call is successful. When I look here: https:

insert-records will use a single with-connection call and a single transaction to wrap the inserts of all those records (maps). On Fri, Mar 1, 2013 at 3:57 PM, Jonathon McKitrick wrote: > Does insert-records with a collection of records have any performance > advantage over calling insert-values

Re: how to get SHA1 of a string?

Larry, What I can advise though, is to look at my library code and it may give you different perspectives. Furthermore, copy, borrow, and steal what you like and make it your own. -FS. On Mar 4, 2013, at 3:17 PM, Frank Siebenlist wrote: > If your code is for production… do not use my code!

Re: Clojurescript bug

This particular problem goes away if you use ClojureScript release 1586 *and* rename the directory src/cljs/aima-clojure to src/cljs/aima_clojure and the file tictactoe-frontend.cljs to tictactoe_frontend.cljs Maybe we should warn on encountering filenames with dashes, or else treat

Re: Clojurescript bug

PS. Incidentally, cljs-1450 has a bug which causes it to emit the unmunged property name regardless of the filenames used. The relevant ticket is CLJS-336, fixed in 9824dbd7c8ac658ebc2d5bc9fa6b5b898f17f659 (releases >= 1503). On 5 March 2013 01:06, Michał Marczyk wrote: > This particular problem
