Re: Why is this Project Euler solution slow?

[Wes Freeman]

Any brute force solution will be relatively slow. The fast solutions
require a doing math to simplify.

Re: 'neostore' does not contain a store version, please ensure that the original database was shut down in a clean state.

[Wes Freeman]

Try starting it up with the neo4j-shell to see if it will go through its
recovery. Like so:
bin/neo4j-shell -path 

And then exiting properly with "exit".

You didn't say how you were importing, but if this happened during an
org.neo4j.unsafe.BatchInserter run, you might be out of luck--the point of
the unsafe package is that it doesn't do journaling, and can't recover from
fatal errors like that. You'd need to start over from the beginning.

Re: 'neostore' does not contain a store version, please ensure that the original database was shut down in a clean state.

[Wes Freeman]

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
written. Usually, if you have your records somewhere you can retrieve them
again, the risk of the unsafe aspect of BatchInserter are mitigated, and
the speed is worth it.

As a side note, you should probably not be running this sort of thing in an
IDE. Make sure you have configured enough RAM for the BatchInserter mmio
options--that is a key way to make performance a lot faster.

This is great. Can you guys put [ClojureScript] in the email subject like
most google groups do? Wouldn't mind if they put [Clojure] in the clojure
emails, either.

Re: Call for volunteers to help moderate a ClojureScript Google group

[Wes Freeman]

I don't tend to filter emails, but just like to go through my inbox and
judge based on topic and subject whether I'd like to take a closer look
before archiving. I'm in too many groups to want to go through filters one
at a time, and currently there a handful that don't have subject markers,
so unless something obviously Clojure-related is in the subject, I have to
dig deeper to know that it's actually about Clojure. If you guys don't want
to do it, I'm fine with continued suffering (I guess I'm a minority)--just
throwing the idea out there.

Thanks for doing it in the ClojureScript group, by the way. :)

Re: Some feedback on clojurescript

[Wes Freeman]

Glad I'm not the only one!

A separate mailing list for ClojureScript would be great. Also, enabling
the label [Clojure] for all subjects of emails would be great (this must be
a setting in google groups, because most of the larger groups have it
enabled), as I filter through a great deal of email I don't care about, and
I actually would like to read the latest emails from the Clojure list.

Thanks,
Wes

Re: Clojure : a good start for non-programmers?

[Wes Freeman]

Yes (definitely not brainfuck), but I would recommend not starting with
something with ugly syntax like C, C++, Perl, or PHP (and many others, I'm
sure) these days. Something friendlier and dynamic like Clojure is an
excellent idea. Two alternatives I'd give a non-programmer are Python and
Ruby.

Clojure gets a bonus for not being object-oriented, in my opinion (you
don't even have to learn what that means--except for java interop, ha).

The syntax for Clojure/Lisp can be hard for some newbies, due to the
massive parentheses trails, but with proper editor assistance, you can
surpass that. http://xkcd.com/297/

I recommend "The Joy of Clojure", although it might be rough for a newbie
after a couple of chapters, it's still excellent. You can always go back to
it, if it gets too difficult to follow.

There's also http://www.4clojure.com/ , and the clojure koans that can get
you some hands on practice.

Good luck!

Wes

Re: how do we go about promoting new clojure libraries?

[Wes Freeman]

For what it's worth, I've organically discovered several of Clojurewerkz's
projects just via google search, so I think Michael's methods work,
although there is indeed a fair amount of effort involved in maintaining
the promotion.

I like the https://twitter.com/nodenpm for node.js npm package updates.
It's high noise, but I sometimes discover something that looks interesting.
Clojars could do something similar--I'd follow.

Re: Questions regarding do form

[Wes Freeman]

Thanks for mentioning doto--hadn't seen that before. Particularly, I think
some of my unit tests can be made significantly more readable with that.

Re: apply: increase performance by 60% for fixed length

What version of clojure are you guys using, just to understand this a
little better? I think apply was given a boost in 1.3 or 1.4--I'm a
relative newbie, myself.

Re: unexpected NaN behavior

[Wes Freeman]

Possibly a simpler example:

user=> (def x Float/NaN)
#'user/x
user=> (= x x)
true

I'm not sure whether true or false makes more sense, personally.

Float/NaN must be instantiating something?

user=> (def y Float/NaN)
#'user/y

Re: unexpected NaN behavior

[Wes Freeman]

I guess it really does do the same thing in Scala:

scala> val f = Float.NaN
f: Float = NaN

scala> f == f
res4: Boolean = false

scala> f.equals(f)
res5: Boolean = true

I guess you really should use == in Clojure, when doing numerical equality.
It even does dynamic typed comparisons better than =. Such as:

user=> (= (/ 100M 100M) 1)
false
user=> (== (/ 100M 100M) 1)
true

Thanks for clearing that up, Aaron.

Re: [ANN] Clojars Releases repository

[Wes Freeman]

+1 on the checksum validation error and ReasonPhrase:Forbidden on the pom.
Using leiningen preview10. I updated my version number to not have
SNAPSHOT, so maybe that's why it's not working, compared to Sean's?

Regardless of the current bug, thanks for working on this functionality,
Phil (and whoever else contributed to it). It felt like clojars (along with
leiningen) was a great convenience, but was a bit weak on the security
side, being too open--and this closes that gap significantly.

Quick OSX/Homebrew tutorial (this is what I did):
brew install gpg
gpg --gen-key
# the following command is sufficient if you've just installed gpg and only
have one key, otherwise you should probably already know how to figure out
which key you want
gpg --export -a
(copy the resulting text into your clojars profile)
lein deploy clojars

Not too hard, right? (Admittedly, gpg is one of those homebrew recipes that
requires symlinking some stuff in /usr/local/share/locale/ to finish
linking; my usual work around is to "chown root:wheel" the homebrew
executable to "sudo brew link gpg", and then reset it.)

Can you give some example syntax for :repositories and ":sign-releases 
false" specifically for clojars? I was hoping to test deploy without 
signing and then try again with signing, to see if that fixes my project.

Re: [ANN] Clojars Releases repository

Ok, if you do a signed deploy, you can scp the pom and jar over to get it
working, directly after.

Like:
scp pom.xml target/clojurithms-0.1.0.jar cloj...@clojars.org:
/repo/clojurithms/clojurithms/0.1.0/
