References, hmmm ... a big, big problem with Haskell is that most of the references you can find are papers; not books or easy-to-learn tutorials. That wouldn't be too bad, but the papers are usually targeted at people who already know the language: a lot of Haskell development right now is involved with advancing the language, and is no use to the beginner and is completely overwhelming. I've found that any introductory books on Haskell are usually targeted at somebody who's completely new to programming, or assumes that you have a functional programming mindset already. (Keep in mind that a lot of the Haskell language designers and implemenators are _really_ smart, and they tend to live in ivory towers rather than try to figure out what the masses are up to :). I don't think the language is actually that hard to learn, but I haven't yet found a book or tutorial that presents the ideas in a digestible way to someone who's new to the language, but is already an experienced programmer using imperative or object-oriented languages. That said, probably the best bet for learning Haskell is Hal Daume's Yet Another Haskell Tutorial: http://www.isi.edu/~hdaume/htut/ I find that the start's pretty slow, and presents things in an order I wouldn't choose if I were to help someone understand the language, but lots of other people have liked it, so hopefully you might too. Another tutorial you may find useful is Tom Moertel's Haskell for Perl Hackers talk: http://community.moertel.com/ss/space/Talk+-+Haskell+for+Perl+Hackers Which covers the basics quite well, but unfortunately doesn't have the time to dive into why the basics are the way they are, and IMHO doesn't really whet the appetite for functional programming. e.g. he explains what higher-order functions are and gives an introduction to Haskell's very powerful type classes, but doesn't explain how make programmer better by showing real, concrete advantages over similar ideas in OO languages. Still, it's a good talk, and most likely he couldn't get deeper into those topics because of time constraints. One tutorial I can highly recommend is Merjis's one for learning O'Caml: http://www.merjis.com/developers/ocaml_tutorial/ch1/ which guides you through the language from the viewpoint of someone reasonably familiar with C++, and even goes into fun stuff like walking through an O'Caml compiler's generated assembly code to show you what's happening underneath the hood, and how it can compete so well with imperative languages like C. I don't know Lisp very well apart from it has macros, and macros are schweeet, so I can't really recommend anything to do with that. Lisp/Scheme are on my list of things to learn more thoroughly by the end of the year :). P.S. I don't mean to sound like an armchair critic and throw stones at the functional language community for the lack of tutorials, but it _is_ hard to get into it if you're already an experienced programmer and don't have three months to learn slowly by osmosis. For me, the reward was more than worth it: hopefully I'll sit down some time and write a tutorial of my own which everybody else can criticise ;). -- % Andre Pang : trust.in.love.to.save -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Re: debian java virtual machine
Just for fun, I'd like to install a java runtime environment. I'm a hobbyist rather than a technical user, but I run Debian Unstable. So far I'm not having any luck. I've downloaded the Sun self-extracing binary from: http://www.java.com/en/download/help/linux_install.jsp Are you sure that is the right file name? I download files ending in .bin: /usr/local/j2re-1.4.1-01-linux-i586-gcc3.2.bin and unpacked it into: /usr/lib/j2re1.4.2_04/ Have I used the right directory? Anywhere will do. But /usr/local might be better than /usr/lib I'm following instructions from the Mozilla site. The Debian GNU/Linux Java FAQ mentions unpacking in /usr/local with links made in /usr/local/bin. I know how to make a symbolic link, but I don't know what to link. http://www.debian.org/doc/manuals/debian-java-faq/ch7.html I link /usr/local/jre... to /usr/local/jdk so that when I upgrade I just reset the link to the new version rather than having to modify paths I've added /usr/lib/j2re1.4.2_04/bin to my $PATH: echo $PATH /usr/lib/j2re1.4.2_04/bin:~/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X 11:/usr/games Should I set that new path in ~/.bash_profile, or in /etc/profile?

Alas, when I visit the java plugin test page, http://www.java.com/en/download/help/testvm.jsp Firefox crashes immediately. Is this a Firefox bug, or do I need to do more to configure the JRE? Some people have had to try a variety of plugins with different browsers to get one that works. How about mozilla, konqueror? Mine is working okay with mozilla When I try to run a .jar file, I get the following error: Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/Object When Java boots it tries to find its bootstrap files such as /usr/local/jdk/jre/rt.jar.

According to http://shootout.alioth.debian.org/craps.php, O'Caml optimised to native code placed 4th (score of 40.9063, implementation name is ocaml), and O'Caml compiled to bytecode placed 16th (score of 16.2858, implementation name is ocamlb). Note that that's a pure speed comparison: no memory usage or lines of code factored in. One interesting thing I didn't expect is that Clean, a very close relative of Haskell which implements the linear types thing I touched on briefly in my talk, is quite fast (placed 5th, just after O'Caml): I guess it goes to show that even a purely functional language (which O'Caml isn't) can be pretty damn quick. I'm fairly convinced that linear types alone account for a huge part of that speed increase vs Haskell's performance given in the ghc benchmarks; it really makes me wish linear types were implemented in a Haskell compiler. There's also been quite a few posts to the Clean mailing lists in the past week which point to some patches to Clean that gives greatly improved performance in some tests; e.g. they claim a 8x speed-up on the Reverse File test after enabling that buffering thing on stdio :-).

Special Interest: Andre Pan - Beyond C, C++, Python and Perl. As a Linux user or developer, you probably know a few programming and scripting languages: shell scripting, Perl perhaps, Python, C or C++, and maybe Java or XSLT. Once you've learnt one systems language or one scripting language, you've learnt them all, right? Especially because of that Turing-complete thing... In this talk, Andre will explore the reasearch amd developments that have happened outside of mainstream programming languages in the past decase, in languages such as Objective-C, Haskell, O'Caml, and Nemerle. The scope of the talk is broad: I'll touch on many topics, such as meta-programming, generics, type systems, and proof-carrying code, without going too in-depth into any of them. (Believe me, you don't want to hear me talk for seventeen hours about type systems.) Most of the topics covered (such as meta-programming) are not language-specific, and can be directly applied to your own work, increasing your own programming expertise and repertoire of techniques. The aim is to make the audience aware of the advanced ideas which have been present in other languages and try to carry over the same ideas in your current programming environment, or maybe even pick one of the other languages mentioned and explore how you can use them as a tool in your daily tasks.

Sorry, I thought you were asking how to unescape the values.
There's no unescaped version of save_parameters, so you'd have to use that
intermediate file, or just do it yourself - isn't it just this:
foreach my $p ($q-param) {
printf $filehandle %s=%s\n, $p, $q-param($p);
}
since CGI handles all the unescaping for your within param.
Cheers,
Gavin

RE: [SLUG] OT: Perl: CGI.pm
G'day...
Ahh... Thanks...
Yes, I was using an temp file. I didn't realise that the param function
could be used in a foreach loop like that. :)
(Still a Perl newbie - I shouldn't be after 10 years of Linux, but
pleased to be programming in it now.)
Thanks

[SLUG] Disaster Recovery in Lower Manhattan presentation tonight
Hey SLUG, [I realize this is rather short notice, but I just got word back that it was ok for non-members to attend] Last year at AUUG's conference I presented a paper on my [then] company's experiences and lessons learned from in the aftermath of the attacks on the World Trade Center in New York. I've been invited to present that paper again to a join meeting of IT students from UTS and the Software Quality Associaton (NSW). http://members.ozemail.com.au/~sqain/ It's tonight (Monday) starting 6pm or so, at UTS: Room 10.04.470 (Building 10, Level 4, Room 4.470), Jones St, Sydney. (Just off Broadway, near Central Station (the old Fairfax offices)) If you're interested in disaster recovery, especially in the context of what a small technology business needs to do to stay afloat, then I welcome you to come. Best, AfC Sydney -- Andrew Frederick Cowie Operational Dynamics Consulting Pty Ltd Australia: +61 2 9977 6866 North America: +1 646 472 5054 http://www.operationaldynamics.com/ -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Asiasat 2-way Satellite
We have a redhat-based billing router, and a customer in a remote part of NT looking to connect through it using Telstra's Asiasat 2- way satellite internet service. Which only has Windows drivers. Not sure I like the idea of a Windows router protecting a Linux router! Has anyone heard of an all-Linux solution? Or, for that matter, any other stable and secure solution?
