I've taken the Seaside JSON example from Seaside 3.0.6 and put it into Altitude. Load AL-Eamples-chc.13.mcz into a working Altitude image (load script at the bottom of this post). The example loads a bunch of pictures from Flickr's Seaside (as in pictures of the beach) account. Then: server := ALServer on: 8624 application: ALExampleApplication new. server start Go to http://localhost:8624 In Seaside it's mainly pure JavaScript. Not a lot of abstraction over the JavaScript there. It's an interesting question what the sweet spot of abstracting over JavaScript really is. Altitude has none. Seaside has lots. For this JSON example it sort of looks the same on both frameworks. Chris | oldPref oldAuth| oldPref := Scanner prefAllowUnderscoreSelectors. oldAuth := Utilities authorInitialsPerSe.

Yeah, it's quite similar because there's very little happening on the server side. The Javascript in the browser does all the work, so all the server is doing is rendering one tag and a snippet of Javascript. I've thought a little bit about Javascript abstraction in Altitude, but it's tricky. One of the fundamental things about modern web apps is that they involve a lot of Javascript in the browser. There are gazillion ways of writing that Javascript, with a ton of JS frameworks, programming styles, preprocessing tools and your-favourite-language-to-javascript compilers. It seems like baking any fixed way of handling Javascript into Altitude would just limit what could be done on the client side. There are a few things that could be really useful—e.g., a DAV server and some way of storing Javascript within the image—but I can't really see doing anything to eliminate the need to write Javascript.

And abstracting over the JavaScript doesn't release a person from the obligation of already knowing the JavaScript that you're abstracting over either. I think I'd have to agree with you that there is no blanket way of abstracting over it so that you're saving effort in all situations. There are some situations where Lukas's work in Scriptaclous was impressive in that you'd write a class and then pop, pop, pop add attributes and you're on your way. I remember translating an AJAX Hacks book example to his Scriptaculous and being impressed by the brevity.There are a few things that could be really useful—e.g., a DAV server and some way of storing Javascript within the image—but I can't really see doing anything to eliminate the need to write Javascript. At STIC Eric Clayberg was using HTML5 2D canvas examples incidental to his Dart presentation. Afterward I found a library called jCanvas[1] that is a plugin for jQuery. I'd like to make some classes abstract over specs for shapes: $("canvas").drawRect({ fillStyle: "#000", x: 50, y: 50, width: 200, height: 100, fromCenter: false });would become something similar to one of Lukas's classes with a few attributes. And then I'd like to code Breakout [2]. That'd be nifty. Chris [1] http://calebevans.me/projects/jcanvas/index.php [2] http://billmill.org/static/canvastutorial/index.html |

The Xtras package in Xtreams uses
libcrypto. The EVP_MD_CTX_init error is saying that the FFI call
to the libcrypto library that comes with OpenSSH cannot be found.
This library is used by Altitude to generate random URLs.
Open your Terminal and "man openssl" to see if you have libcrypto. I think it comes standard on a Mac. If that's the case, then perhaps your FFI cannot make the call to the library.

I have a Mac with 10.7.2. I've never had a problem with Altitude on Mac. I've encountered problems on Linux due to the FFI. Run your tests for FFI. Are they all green?
