I believe Clojure is wrapping the java.sql.SQLException in a
java.lang.RuntimeException because of reasons[1][2], so you'd need to catch
java.lang.RuntimeException and examine the exception's cause property to
get the real exception.
Agree
Most probably, your template is a lazy seq and pprint forces its
evaluation, which is why the error happens at the pprint point.

Yep, thanks, my bad. I got the point.
Actually, what I was trying to do, is to prototype multithreaded i/o
operation via reducers. And then use fold to regulate number of concurrent
operations.
But now something tells me I am doing not very clever thing.

Thanks Alan, looking into it.
By the way, fold function has [n combinef reducef coll] implementation,
where n is number of elements collection is folded by. 512 is just the
default.

Hi All,
I was recently looking at how to make better use of parallelisation for
simple tasks in my compojure app, I had a construction similar to the
following:
(views/some-view (api/api-call-1) (api/api-call-2) (api/api-call-3))
It seemed that the easiest way to introduce some parallelism
guv is broken if your let form introduces bindings that depend on earlier
bindings:
user= (plet [a 2 b a] b)
CompilerException java.lang.RuntimeException: Unable to resolve symbol: a
in this context, compiling:(NO_SOURCE_PATH:1)
user= (clojure.pprint/pprint (macroexpand-1 '(plet [a 2 b a] b)))
It's not too hard, though, to write a plet form that first does some
analysis on the bindings to see which of them depend on which others. I
believe I mentioned this elsewhere in the group as an example of why a
macro might want to macroexpand its arguments, because doing that is the
simplest way

Hi All,
You may want to take a look at Prismatic's graph library, it does what
you've described above in a slightly different way.

I am in emacs, in an nrepl session, and I do this:
user (load-file /Users/lkrubner/projects/tma2/cacher/src/cacher/core.clj)
ClassNotFoundException org.jsoup.Jsoup java.net.URLClassLoader$1.run
(URLClassLoader.java:366)
Why do I get that error? The file starts like this:

That library and others like it (e.g., oh, I dunno, babbage) impose more
overhead, though, than a simple let form, if you just want to use something
one-off in one place.

Did you restart nREPL after adding the JSoup dependency?

I'll take a blind stab at this and say that Erlang might actually do

The biggest issue with these sort of chips (this design is known as the
Intel Xeon Phi) is memory. 50+ cores sharing the same memory bus means that
cache miss penalties go through the roof. And unless these chips are
optimized for efficient CAS operations that can be a issue as well. See for

I don't want to be too much of a downer, but our experience running Clojure on
48-core machines was pretty depressing, with our speedups often being near zero

It looks and works a lot like cucumber. But more clojure-y.
Write tests at a super-high level. Test by observing side-effects.

To post to this group,
E-mail thread had less to do with issues of Clojure per se, but more with
issues the JVM had running on a 48-way machine. Or am I missing something?
IIRC the Azul people played with Clojure a bit, I wonder if their suped-up
JVM allows Clojure to perform any better.

I'd put it on Clojars but I can't really figure out how to deal with this
gpg stuff. Seems way more complicated. Wish clojure had something easier,
like homebrew and melpa. But whatever.
