I write again my post because the previous was bad written and I want to
respect the Englis language the more as I can.
With your question, I'm feeling you think each item has a different hash
code. But it's wrong. You can meet collisions.
An hash code is not an id, it's a way to find an

I need to parse a csv data and want to know what are the main diferences

Thanks.

Having both options available also allows you to make
NullPointerException-averse decisions as appropriate.
That is, in this function:
(defn foo [a-map]
(a-map :foo))
I'm potentially exposed to an NPE if the given map is nil. By rewriting it:
(defn foo [a-map]
(:foo a-map))

We run a Clojure group out of our company's office. We want to put
together a hack night where we work on something meaningful. To that end I
thought I'd put that question to the wider community: what could be

I used an early version of Clooj in a workshop some time ago, but got
burned by some bug that rendered the REPL crazy and shredding people's
code. That scared me away. Probably much better now, though.

I have used the isBlank example in presentations. It's not a bad starting
point. Might look at how it could be used in a workshop. Thanks.

I also suspect that the IDE is important. These guys are experienced
people, and I think that once they have an environment that works and they
have some control over, they will have a foundation. I think they need and
want to know how namespaces work, so that they can see how to modularize
This is good advice. I think you can cover a lot of ground using this
approach, which I guess you need to do when writing a book.
As I mentioned in another post, I believe I have to choose between covering
a lot of ground and building them a foundation that they can experiment on
further.
How do we get ourselves to the list? We rely on Clojure heavily at
http://beanstalkapp.com and we're working on rewriting even more critical
pieces of our infrastructure in Clojure. I tried to edit the page, but it's
locked.

In this case, a good question could be are 0 and nil the same?
In some languages like C or C++, NULL and 0 are the same (at least, for
x86 Intel architecture, I don't know for others). You find some old code
where you have ptr == 0 instead of ptr == NULL. And often, you have test
for pointers
Yes that's exactly what I meant, sorry I think I didn't express it very
well. Of course I know about hash collissions, but (maybe mistakenly) I
always thought that they happened in relatively rare cases. Interestingly,
'() has a hash of 1 which is the same as the hash of integer 1!

The rarity about the hash code depend essentially how it is computed.
On a project, the string hash codes have been the 2 first letters.
