I corrected the error and saw an update to the tute.

Re: [Catalyst] RFC: The paradox of choice in web development
Kieren Diment you really seem like such a nice, tolerant and decent person. I could buy the book God willing only to make you happy, seriously. I personally think that 30$ for a nice book, it worthwhile. Of course if you feel like buying 20 books, 20 * 30 = 600$ , well not so nice then. But as Kieren predicted, books and publisher will eventually have to offer a lot more added value to create customers. As more ppl blog and write docs for and about their technologies of choice less people will be willing to pay for books. Not to divert from the thread main topic, I believe, we are bit ignoring the elephant in the room. When Catalyst is not chosen I personally believe it the combination of two things 1. Perl is no longer perceived as an easy language, or language that make development easier. 2. Catalyst perceivably doesn't offer enough added value for developers who are not that much into Perl to make the sacrifice and use Perl anyway. Blaming it on too much choice is not really there. New Perlers (and I consider my self one) know what the best modules are DBIx::Class DateTime XML::LibXML Catalyst, CGI::App for starter CGI for complete beginners Moose HTML::FormFu and so on I want to say, that today, there seem to be a general consensus on what the best modules are ... New Perlers are not confused. Those who disagree, maybe old Perlers. I do wish to see good existing success stories about Perl in sites like infoq, hackernews (ycombinator) and any other site that is popular enough to spread the good word.

Re: [Catalyst] RFC: The paradox of choice in web development
From: Ali M. tclwarr...@gmail.com When Catalyst is not chosen I personally believe it the combination of two things 1. Perl is no longer perceived as an easy language, or language that make development easier. More exactly,, Perl is considered a language hard to learn, that creates a code hard to maintain, a language that uses a strange OOP style (because I guess there are no books for Perl beginners that teach about Moose or Mouse), a language which is too flexible and because of this it is not prefered by the large teams of programmers because each of them could have a different style. 2. Catalyst perceivably doesn't offer enough added value for developers who are not that much into Perl to make the sacrifice and use Perl anyway. If the programmers are not that much into perl, this means that they don't know how to use DBIx::Class and Catalyst and possibly other few modules which are usually used by Catalyst developers, and in that case they can't understand the power of Catalyst. If Catalyst wants to compete with RoR or other frameworks, it should be as easy to install as those frameworks, and the simple apps should be also very easy to create. The comparisons between web frameworks are not based on the number of the requests they serve, or on the number of database tables they manage, or on the number of backend servers they are installed on, but on the number of web sites that use those frameworks, so those comparisons might show that there are 100 sites that use RoR and only 5 that use Catalyst, but don't tell that 3 from those 5 sites that use Catalyst have 3 times more visitors than all those 100 sites that use RoR. And of course, the conclusion is that RoR is much better. I think that the success of other languages, especially Python is also due to the fact that they support better Windows than Perl. WxPython is better developed than WxPerl, there are even screen readers that interact with the GUI of the OS in Windows and Linux, and finally... the number of programmers for Windows is bigger than the number of programmers for Linux. Most Perl programmers use to consider good to publicly despise Windows and those who use Windows, and also consider that Perl is a language for the web, while those who use Python or even Ruby consider them very good languages for creating programs with a desktop GUI. PerlScript as a client language, or one which is used in .hta applications or Windows Scripting Host, is pretty hard to use if we compare it with VBScript or JScript, and even if we can say that Perl can be used in places where other languages can't be used, practicly it can't be used really successfully. Of course, there are no manuals or training materials for using PerlScript, which are newer than 7 or 8 years. Even on Symbian, Python is better developed than Perl, which practicly I don't think it is really used on the mobile phones. I've seen a few persons that say that yes, there are many perl developers that create modules for CPAN, which is great, but the core Perl development team is probably very thin, Perl 6 is not ready yet, while Python 3 was launched and it has a great and powerful core team. Python is sustained by Gmail and Sun, which create programs that use it, but Perl, even though it is used by big companies like Oracle, just use it, and don't seem to sustain its development. I think these disadvantages also influence the potential users to think that even the Python frameworks are better, which is not true.

Is there even some kind of explanation for the really FAT memory footprint? Currently, our project allocates 330MB RAM right after startup (with myproject_server.pl or fastcgi). Over the time this is getting worse; some month after the projects start it used about 80MB and we think with some additional controllers and stuff it will need over 500MB. I know there is some advent calendar entry about restartig the catalyst-process when it reaches a memory limit (what is good - our processes tend to grow up to 1GB), but this doesn't help at startup. Is this normal behaviour? The problem is, we use multiple instances of the application. So every customer has his own catalyst instance with own database and - of course - own fastcgi-process. Currently we are running it on a machine with 16GB of RAM and will soon get to the physical and budgetary limits. Is Catalyst just not intended for this kind of use (and more like one server, one site) or is there some black magic we just haven't found yet? Btw: Neither reducing the count of the DBIx-models nor disabling the debug-mode does have an impact on memory footprint. Thanks and regards, Thomas Weber To me, it sounds like you have a memory leak. I have Catalyst applications that run for weeks without restarting, and take 143MB of ram at start up and not any more as time goes on. This particular application has 177 DBIC Schema classes, 32 controllers and 3 models (which are simply adapter classes). Check out Devel::NYTProf and perhaps exit right after startup, perhaps you have some relations that are going bad?

Yes please, a full example tutorial is just what we need! But what kind of example are you planning to do? How about you cover CRUD, to build something like... yet another Blog? Have a couple of tables with relationships like author, story, tags, categories, comments... link them up with dbix::class, use formfu for the forms, and to make it interesting: add some ajax on the forms to validate the input, without reloading the page. keep the example simple, yet functional, so that others can build on it and extend it.

Not everyone has the same skillset. Some people you want spending time working on the code and please don't use your special brand of 'help' on new people. Other people have excellent communication skills, and may not necessarily be at the level of coder you want making best-practices tools for others (but Catalyst helps them write their own stuff that still works, even if they've still got a few lumps to take as a coder.) It's also important to keep in mind that 99% of people that read social news sites (like Programming Reddit) are idiots that only read things they agree with. Wasting your time trying to educate these folks is just going to make you very, very bitter. There's a lot of truth to this. There's a reason that programming language discussions in the wild Internet are so personal - because they are. I've invested a lot of time becoming a perl expert, not a java expert, and so I do care that most of the semi-technical people out there incorrectly think that java is a better language - it means less job postings, so less likelihood I'll be able to end up with something where I like the work and salary. But since these things are so personal and high stakes, they're deeply unpleasant to participate in and not winnable. Never post in the comments of a programming language discussion on Slashdot - it's just unpleasant. On the other hand, there are less hostile forums, and they do matter. Not that long ago, I was starting up a major web project and needed to pick a platform to start with. I chose Catalyst for several reasons. This active mailing list is a big one, the existence of your book was another. Being able to work through the example in a few days gave me a lot of confidence that I could work with the framework. Seeing Catalyst mentioned in talks at the Open Source conference, seeing it mentioned in blog posts, it helps the person choosing to think, This is the project that's actively improving and I won't regret sticking with in six months. As opposed to, for instance, Solstice - the mailing list is almost dead, there's very little that turns up on a web search for help, no basic 'make a sample app in a day!' document, no buzz. It's obviously much more important that Catalyst works well, is extensible, and has good support, but that sort of thing is very hard to actually see when you're buzzing by options if people aren't talking about them. I think Catalyst's primary market right now is experienced perl developers that have built frameworks from scratch and don't want to do it again, and it's emitting decent pollen to attract those.

My working list is as follows (in no particular order.) 1) 'Getting' DBIx::Class (starting from a straight SQL-users point of view) Areas you could focus on: - Basic Form handling, implemented with a specific module: formfu, rose, etc.. - Possibly: Form handling with AJAX - CRUD operations with multiple tables - Building your own fat model API, to put as much logic into your model and then use this API in your controllers. 2) Basic Cat toolkit - the basic pieces you will want to produce your average web app. Deployment with FastCGI Putting dependencies in your Makefile.pl and how to install it on another box. 3) Walkthrough of creation of a simple app end to end. Yes please, a full example tutorial is just what we need! But what kind of example are you planning to do? How about you cover CRUD, to build something like... yet another Blog? Have a couple of tables with relationships like author, story, tags, categories, comments... link them up with dbix::class, use formfu for the forms, and to make it interesting: add some ajax on the forms to validate the input, without reloading the page. keep the example simple, yet functional, so that others can build on it and extend it. I'd be interested in writing some parts of a tutorial like this.

Re: [Catalyst] RFC: The paradox of choice in web development
Actually, the community will probably benefit most from writing code. Talking about talking about something doesn't actually buy you much. New modules that make programming easier are definitely more appealing all around. Well, yes and no. Not everyone has the same skillset. Some people you want spending time working on the code [...] Other people have excellent communication skills, and may not necessarily be at the level of coder you want making best-practices tools for others Exactly. As mst said [1], If you aren't good enough to write code, submit patches. If you aren't good enough to submit patches, write documentation. If you don't know enough about the project to write documentation, point out what's missing from the documentation to make the project easy to understand. Anyhow, CONTRIBUTE! [1] http://www.shadowcat.co.uk/archive/conference-video/yapc-eu-2008/you-arent-good-enough/ There's a reason that programming language discussions in the wild Internet are so personal - because they are. Paul Graham's last essay is exactly about this: Keep your identity small - http://www.paulgraham.com/identity.html I chose Catalyst for several reasons. This active mailing list is a big one, the existence of your book was another. [...] Seeing Catalyst mentioned in talks at the Open Source conference, seeing it mentioned in blog posts Spot on, again. When someone language-agnostic makes a decision to use a web framework, what can they do? a) try building a sample project in a few different frameworks from the ~130 out there b) evaluate what's being *talked about* those frameworks. People in the a) group are extremely few, and never get far. Take http://chrislaco.com/articles/ as an example. And of course they don't get far in objectively evaluating a bunch of frameworks: - it takes time to learn enough about each framework to know that you haven't disqualified it due to your own ignorance - it takes effort to actually build your sample project and iron out the kinks - once you pick 1 out of N frameworks, most of the knowledge learned about the other N-1 ones will soon become useless - sample projects may have little to do with how a framework would handle real-world complexities and scenarios. If this isn't a good example of analysis paralysis or the paradox of choice, I don't know what is. What will therefore someone who wants to pick a framework most likely do? b).

How do I have a wrapper template, yet also support other forms of output like AJAX/JSON/XML? What does this method or that method do and where should they be used? How can I use two separate Authentication systems for different parts of the app? Just brief FAQ-style code snippets with good explanations... (Maybe someone could whip up a Catalyst FAQ app to handle question submissions, community answers, categorisation, searching, etc... Would be better IMHO than a single Wiki page... ^_^) *Clarification on the Path and Args (and others?) sub parameters, with examples on advanced usage. *Best Practices - I guess this comes in to the earlier points as well. Rather than munge something together that works, if I can easily find a code snippet that does a similar thing, then I'll use that snippet. For example; How do I provide a controller which handles both a HTML and an AJAX response? How do I specify the AJAX qualifier in the query string? Do I use a query parameter? Or append something like :ajax to the URI? Or go to a completely separate URI? How do I set out my Controller methods to most efficiently handle both situations without code duplication? *Interactive Demo/Tuts would be really good. If there's so many CRUD systems to choose from, then having a live demo of each next to the relevant code snippet would really help quickly highlight the pros cons of each. *Better linking/cataloguing to documentation.

There's also, it seems, a quite extensive Cookbook in the CPAN documentation - yet the Wiki doesn't link to it or mention it? As I said, I found the Tutorial to be really good, but I find I'm using the Tutorial as my documentation for my own app, rather than looking straight in the manual, or in the wiki resources... The Manual Cookbook seems good - I should use it more often. I'm pretty new to the Catalyst community, and still very much a Catalyst newbie.

Re: [Catalyst] DBIC::Schema issue - out of ideas.
Hello Alejandro, Yep, I made sure that the 'Schema' subdir does not exist before I ran the following command to create static ORM files. myApp_create.pl model myAppDB DBIC::Schema myApp::Schema create=static dbi:Pg:dbname=myApp myAdminUser mypassword Yet, i followed tute 3 of the catalyst manual and DBIC docs to no success. What am I missing? Quoting Alejandro Imass alejandro.im...@gmail.com: Are you using a static schema? (it seems). If so, and unless you have customized the generated Schema files, it is usually safe to delete your Schema classes and generate the ORM model again. If you re-generate your static schema, on top of the old one, the model class will not overwrite and you will have a .new class sitting beside the old one. Also the schema loader does not deal with table drops and I think it doesn't deal with updates either, so you are always better off by deleting your schema classes prior to reloading your static schema.

The functionality and scope of the job tracking system has changed so instead of throwing more money in a proprietary, closed system that requires a costly application on each desktop I'm suggesting writing it as a web application with Perl Catalyst. The only problem is that I've been told we would have to use Java Struts since it's our corporate standard for web applications. Perl, ironically, is used in quite a few places in the company, mainly in utility scripts. However, since we don't have anyone whose job title is Perl developer we can't use it for web applications. This is hardly unreasonable. I've worked at a number of smaller shops where we were developing a Perl-based app. If a developer had decided that they wanted to throw together some important tool in Java (or Python or Haskell or Smalltalk or ...), that would have been problem. The investment in a language is bigger than just the programmers, even. You have build deployment tools, automated testing setups (you do, don't you? ;), sysadmin knowledge, packaging infrastructure, and so on. Some of that may be language-agnostic, but often a lot of it ties into the language and its tools. Once you've made that investment, it makes sense to stick with it. Just because Catalyst and Perl are great tools for webapps doesn't mean that they're the _right_ tool at your job. -dave /* http://VegGuide.org http://blog.urth.org Your guide to all that's veg House Absolute(ly Pointless) */ ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/
