Have you tried increasing the heap size of your JVM using the -Xmx and -Xms
options?
We're loading some spreadsheets that are 80M in size and have to run with a
~1.5G heap to handle this...

You can't really avoid the instance checks: the underlying mechanic is that
the JVM needs to figure out somehow at runtime which overloaded method
version to call, since all it knows at compile time is that it has an
arbitrary Object.
instance? is the simplest way to do this. There are some

Very true... it's a tradeoff:

The alternatives to BatchInserter are to just use the normal Java API and
batch things up into large transactions--~10k things at a time is probably
a good first try. You'll probably get 1/4 to 1/2 of the speed of the batch
inserter, but it won't crash unrecoverably, as the journal file will be
Sorry, full of questions about type hinting at the moment.
I've found myself writing a lot of expressions like this:

(into-array OWLClassExpression

(ensure-class o disjoint)])

Hi all,
I'm happy to announce that a first tutorial on introducing OpenCV development
with clojure has been just merged in the official 2.4 documentation branch
https://github.com/Itseez/opencv/blob/2.4/doc/tutorials/introduction/clojure_dev_intro/clojure_dev_intro.rst
It's only the a very
The only thing I can think of off the top of my head is to write a
hinted-array macro that turns (hinted-array Class expr) into ^Class
(into-array Class expr). Emitting type hints or other form metadata in
macros is do-able, but sometimes a bit tricky. Something like this might
work (untested):
Implement the nand function, simulate registers using nand,
and you can do anything since nand is universal. Or, if you
really want to get primitive write a turing tape processor.
Pain all the way down :-)

A couple of updates on things that were discussed earlier.
1. Thanks to this thread we are now talking to quite a few awesome people
from North America. So, not everyone able and willing to write Clojure on
the day job has this wish fulfilled, after all :)
2. We are not doing H1Bs/relocations
Congratulations Mimmo, that's great news. I'd like to play with OpenCV at
some point, I'll definitely use this if/when I do. And yes, I totally agree
- Seesaw is the gold standard with lib wrapping IMO, it's a fantastic piece
of work.
Cheers,

As an experiment, I've written a DSL that generates database queries using
*effectively* only the data. The query logic is derived from the data
assemblance and choice of data structures (or types). I am at the stage
where I have all the logic working, and I am now moving into perf testing

Hi folks,
Albeit a little later than I'd hoped, I've written a post giving a
