Call For Participants: Smalltalk Superpowers (Their Uses for Good or Evil)
by Travis Griggs 13 Sep '08

13 Sep '08

http://smalltalk-superpowers.org/ We're looking for your story! OOPSLA 2008 will feature the "Smalltalk Superpowers (Their Uses for Good or Evil)" workshop, on Monday October 20, 2008. It's a workshop where we tell stories. Stories about the programming superpowers that we've seen peers wield (in any dynamic language, not just Smalltalk), or have wielded ourselves. By "superpowers", we mean those features that give the programmer abilities beyond those of normal object-oriented programming. Examples in Smalltalk include #become:, #changeClassTo:, #doesNotUnderstand:, thisContext.... We want to catalog and discuss uses of these superpowers, and whether their use ended up being the hero of the day, or the villain of the year. We invite you to come and join us! You're free to just come and listen, but to make our little story hour worthwhile, we need a good number of stories, so please consider submitting and sharing. You don't need to be a superpower user yourself, your story may have been from the viewpoint of the innocent bystander, rather than the doer. So jump to the link at the top of this email, and find out how to submit your story. We look forward to hearing from you. And to seeing you at OOPSLA. -- Travis Griggs Objologist "Every institution finally perishes by an excess of its own first principle." - Lord Acton

WAKom configuration for static files does not work if image is moved to another host
by Norbert Hartl 11 Sep '08

11 Sep '08

I'm developing a web application on my linux laptop. To be as self contained as possible I configured WAKom to serve the javascript and stylesheet files with the following configuration: ma := ModuleAssembly core. ma serverRoot: (FileDirectory default directoryNamed: 'webroot') fullName. ma alias: '/seaside' to: [ma addPlug: [:request | seaside process: request]]. ma documentRoot: (FileDirectory default directoryNamed: 'webroot') fullName. ma directoryIndex: 'index.html index.htm'. ma serveFiles. (HttpService startOn: 9090 named: 'httpd') plug: ma rootModule This works quite well. But if I move the image to another host the web application works but the image does not serve the static files. For every request I get an 404 from Comanche. Any ideas? I've checked that there are no permission problems or similar things. Norbert

External control for call/answer
by VAM 09 Sep '08

09 Sep '08

Hi! I have next situation: There are three components: A, B and C. A rendering books list. User select in A a book and B rendering it properties. In B user can choose an action and B calling C (throw B call: C). If user again select another book in A, it need again render B with book properties. But now B call C and render C. How return from C? I see one way: A on selection announce event. C catch announce and execute "self answer". Exists another solves? -- View this message in context: http://www.nabble.com/External-control-for-call-answer-tp19388560p19388560.… Sent from the Squeak - Seaside mailing list archive at Nabble.com.

[Newbie] Storing state in cookie instead of URL
by Stef Telford 07 Sep '08

07 Sep '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Everyone, So, I am playing around with Seaside.. generally digging it and glad that I can do web development in my favourite language (Ruby is nice, but, well, Smalltalk is nicer ;). I have taken the first rudimentary steps, running Wakom, creating a simple page and storing state. However, when I was in the configure panel for my application, I switched the 'Use Session Cookie' to 'true', yet I still get the _k in my URL. I would have expected the value for _k to be stored in the session cookie. If this doesn't do this, then I have two questions; 1) how do I get Seaside to use _k in cookies ? and 2) what -does- 'use session cookie' do, if it doesn't put the state (_k) into the cookie ? Also, if anyone has some nice fileouts of more examples, that would be great. I tend to learn from taking things apart :) Thanks and Kudos on giving Smalltalk a nice web framework :D Regards Stef -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkjED8YACgkQANG7uQ+9D9U52QCghE1tU3GFKWpaRyXxI72+SOOr xz4AmwdXSB7K1vSnpnoS9rHhPn+TVaQf =Rs+7 -----END PGP SIGNATURE-----

#script: part of the tags
by Sebastian Sastre 07 Sep '08

07 Sep '08

Hi there, Today I've found a surprising behavior (about a 'dom:loaded' event reaction which was not executing) and debugging that lead me to the #script: method of WATagBrush which has this code: script: aPrototype aPrototype isNil ifTrue: [ ^ self ]. (aPrototype respondsTo: #id:) ifTrue: [ aPrototype id: self ensureId ]. aPrototype session addLoadScript: aPrototype That means that silently Seaside decided to put the script part of the tag in the onLoad section which is IMHO a very poor choice this days. If the idea is to mantain that silent manipulation of the script tag, I recommend a review to use 'dom:loaded' instead of that because it will be fired just after the html is loaded and before the images are loaded and, depending on the page, that could make a lot of diference to the user experience. If not, I recommend two methods. One called #script: behaving as intuitively expected for the tag and other with the "enhancement" but making it explicit with something like #onDOMLoadedScript: so the Seaside developer can choose instead of being (poorly) surprised. Cheers, Sebastian Sastre

Seaside Scaling - How successful?
by Rich 07 Sep '08

07 Sep '08

I've been looking for a framework that will grow with my company's projected online growth rate and Seaside looks very interesting. We developed a Java based web site for a beta product, but I'm not happy with the results or the amount of code/time required to make things work with Java. I'm looking for something that will have a faster implementation and also scale well as we grow. I stumbled across Seaside on Blog post and thought I'd take a look. Seaside looks like it has some very nice features and I've been spending the last couple of days doing some of the tutorials and watching several of the "Why Seaside" talks. Thanks to your community for posting those. I do have some reservations about Seaside and I'm hoping that the members of this list can point me in the right direction for the answers or have some of their own success stories. Here are my concerns at this point in time: Scalability - How does one scale Seaside? I've seen GemStone/S to help with persistence and using Apache for static content. These seem very logical, but I'm still wondering what it takes in hardware to support 1K, 10K and 100K unique visitors per month to a Seaside based site. I know this will be code dependent, but I'm interested in seeing 1) if its even possible to hit in excess of 100K visitors per month and 2) what it would take from a hardware perspective to hit this number of visitors. Memory Requirements - I read in the archives, and I'm betting this is an older pre 2.8 rev memory number, it takes 2M per client for Seaside. Is this still the case? Hosting - What is the best way to host Seaside if you want to use someone else's hardware? Has anyone implemented an AMI on AWS for hosting? Success Stories - Any success stories where a site is servicing in excess of 5K visitors per day using Seaside? If so, what did it take to get here and would you do it again? How are you handling persistence? What is your limit based on current hardware/software? Learn Seaside - What is the best way to learn Seaside for a non- Smalltalk developer? Any information you could provide that would help me make this decision would be much appreciated. Thanks for your time. Rich
