Hi
I have a database that has a table with complex java objects stored in
a binary field.
In java i would do something like:
protected Object read(byte[] buf){
Object obj = null;
if (buf==null) return obj;
try {
ObjectInputStream objectIn =

I can't say I know much about JNI but I've used some libraries like

An updated version of the code for datatypes[1] and protocols[2] is
now available in the 'new' branch[3].
I have done a lot of work on performance, and refined the design. The
big news is that you can now directly implement a protocol inside a
deftype, and you can also reify protocols. This cement

The title says it all. Is there a nice, concise, Clojurey way to
convert a vector [a b c d] into [[[a b] c] d]? It's fine if the
vectors are sequences instead. I can't think of a way without a loop,
but I suspect there's a much shorter way.

When I finally get around to working on my clojure polyglot
implementation for maven 3 I'll probably be basing my project
structure off of leiningen, which should mean anything IDE using maven
should work with the project file. Sadly I'm still trying to nail
down some time to look at this project
I see- Sounds like we're on the same page. :)

I did not claim otherwise. The effect of with-precision is like an implicit

What is the correct way these days to upload a file to the "Files"

I checked the info on the group, it looks that only "managers" can

who do I send the files to)?

Jim,
I think I can see how to write a library that would scale across any
number of servers and I don't think it would be too difficult. I've
got other itches to scratch before I'd get to it, but if people
started asking for it (or someone wanted to sponsor the work) I might
decide to do it sooner
Re: not all web applications have to scale - true, but I haven't worked on
one of those since about 1998 (this is an analog to Rich Hickey's statement
about not having to build non-concurrent programs in the last N years),
including "admin-like" things. Further: once you build all those

setScale returns a new BigDecimal with a given scale, it does not
change the original value.
e.g.)
user=> (def mybd (BigDecimal. 40))
#'user/mybd
user=> (.setScale mybd 4)
40.M
user=> mybd
40M

Not every web application has to scale. I think that continuation based
stuff rocks for adminstration interfaces.
The main benefit with continuation based stuff, is that it's possible to
build something that is more application like, so that one can avoid
building wizards, and having to split up s

That's what with-precision does
