image_science version 1.1.3 has been released!
ImageScience is a clean and happy Ruby library that generates
thumbnails – and kicks the living crap out of RMagick. Oh, and it
doesn’t leak memory like a sieve. 
For more information including
build steps, see http://seattlerb.rubyforge.org/

For what it’s worth, I run rmagick in a (lightly-used) production
service on a win32 box and have had no problems, memory usage appears
stable over time. I had actually considered image_science as an
alternative, but given the lack of an image_science gem that doesn’t
depend on having a c compiler on the box (a relative rarety in the win32
world, sadly), it’s not an option for me.

So? He and I disagree. Big deal. We’ve done it before [1], I’m sure
we’ll do it again.

More FUD! How many times I’ve heard this crap I have no idea… We’ve
been shipping inline with inline_package for over 2 years now. How
long do you have to propagate this?

Thanks for reposting my earlier request, James. I’ll repeat it here for
emphasis:
As of this moment there are no open bug tracks for RMagick memory leaks
on RubyForge. All the RMagick “leaks” I know about are addressed in this
entry in the RMagick Hints & Tips forum:
http://rubyforge.org/forum/forum.php?thread_id=1374&forum_id=1618.
If you know of a leak that isn’t addressed by that tip, I’d love an
opportunity to fix it. Would you mind sending me a script that
reproduces the leak? I need a script with no extra gems or libraries,
just Ruby and RMagick. No Rails, attachment_fu, file_column, gruff,
scruffy, or whatever. Let me know what O/S you’re on, what version of
RMagick and ImageMagick/GraphicsMagick, and what version of Ruby. You
can send it directly to me, post it here, or open a bug track on
RubyForge.
By the way, since I originally posted that request on the 17th I’ve had
no new bug reports, so please, send 'em in.
Ryan, glad to see you’ve constructively channeled your frustrations with
RMagic.
Two wrongs don’t make a right but two developers with differing opinions
make two very useful pieces of software. 
Keep up the good work guys

Well, I was thinking it might be worth it to submit bug reports to
the tracker so he could fix them. I see from your article that
you’ve had trouble with that in the past though. Fair enough.

Have you guys had problems deploying Rails apps with ImageScience and
Mongrel? I tend to get strange errors about RubyInline not having
access to
the home directory. Similar to the problem described here (
Mongrel and RubyInline - Rails - Ruby-Forum), but with this fix not quite
being
100% effective.

That’s the first I’ve heard of for mongrel. I just dealt with
something similar on apache and blogged my fix for that. I rejected a
bug yesterday for a similar sounding Locomotive bug but the reporter
couldn’t and wouldn’t provide a reproducible test case (besides an
entire rails app + downloading locomotive (46m) etc etc). No clue if
that is related or not as he just couldn’t get any clarity on the issue.
So, try my blog. Let me know if that works for you.
P.S. Setting HOME is not the answer. Set INLINEDIR instead.

Apologies for the misinformation. All I know is that on my win32 box, if
I gem install image_science and all its dependencies,
Could I get some help setting up image_science in my win32 environment?
I’ve never worked with RubyInline and I think that’s where I’m getting
stuck. I have both Visual Studio 2003 and 2005 installed. So far, I’ve
gotten:
