Does Zinc support the web socket protocol? Or, is it likely to in the near future? Cheers Andy

First Steps

Hi, well, I think I'm starting to get the object thing. I coded up the beginnings of a BTree package .. and I think I'm sold on Smalltalk - I really love the debugger!! If anyone has 5 minutes to kill having a look and give some feedback, I'd appreciate it. It's in squeaksource - I think I set it up so anyone can see it ... let me know if it isn't (and how to make it visible too! :) It only has an add function so far (and the page search is only linear - I'll get to that). useage x := BTree withOrder: 2. x add: 11.

MAConditionError opens a debugger
by Romain Verduci Aug. 12, 2011

Aug. 12, 2011

Hi, I have a problem with my seaside application using MAConditionError. It's suppose to display a message error and in my case it opens a debugger. Code with MAConditionError : MAConditionError description: self description signal: 'Invalid name or password.'. I don't understand why it does this. To simplify the explanations and reproduce the bug, you can: - download my image on: http://demo.ovh.com/fr/466c8bec0e28467ab3d473647833e0e8/ - copy the service/ dir on your root dir (/) - run the image - go to localhost:8080/sh - try to login with a fake name And then the MAConditionError opens a debugger when there is an error in login. Thanks Romain

Best way to stop a process listening to a socket
by SÃ©bastien Bigaret Aug. 12, 2011

Aug. 12, 2011

Hi all, Suppose I have a process started w/ fork executing socket>>waitForAcceptFor: with a long deadline. Now suppose that I want it to to stop waiting, before the deadline expires. To stop it immediately, I've found out that signaling it with Process>>signalException and handling it in the Process' code by a Process>>BlockClosure>>on:do: works as expected. Is this the correct way of doing it? Should I make a specific 'Error' subclass for this? Thanks for any advice. __ SÃ©bastien.

Recommended logging API?
by SÃ©bastien Bigaret Aug. 12, 2011

Aug. 12, 2011

Hi all, Is there a recommended package to use for logging? I've found out that Object>>log exists and shoult be used instead of Transcript>>show, and http://www.mail-archive.com/setools@lists.squeakfoundation.org/msg00108.html speaks about different packages or "adapters". Is there a recommended one or a recommended way of doing it in Pharo? (and/or a document I should read) Thanks for any advice. __ SÃ©bastien.

display form in window; move it around; close it
by C. Hever Aug. 12, 2011

Aug. 12, 2011

Hello, all. I plan on visualizing fractals in Pharo sometime soon. However, there is a bit of a snag. I've figured out enough to write pixels to a form and save it as an image. However, that lacks the immediacy of being able to see it right in Pharo. Morphic is very confusing so what I'd like to know is how I can draw an image in a window, have all the normal window stuff like move and resize, maybe update it, then delete it when I'm done. TIA

Hmm, this is true :-( Maybe somebody changed that at some point for performance reasons? Private projects are definitely not visible in the original implementation ( source.lukas-renggli.ch has many private projects that don't show up).

[ANN] LatAm Squeaksource Mirror
by Johan Fabry Aug. 10, 2011

Aug. 10, 2011

Hi all, I'm happy to announce that we have a public, read-only Squeaksource mirror up and running at the Universidad de Chile. The URL is: http://www.dsal.cl/squeaksource/ TECHNICAL DETAILS BELOW. Feel free to broadcast this announcement! MOTIVATION: For us, Switzerland is a long way and the connection to Squeaksource has always been painfully slow. We've set up this mirror to help to address this, and I imagine that it will be of use not only for the Chileans but also other countries in latin america, which is why I am announcing it here. ITS TRANSPARENT: I've worked out a way to make the use of this mirror transparent when using Pharo 1.3: you just use monticello as always, and have a setting to redirect loads from Squeaksource to wherever you want. I have successfully loaded Moose and Seaside from the mirror using this package, so it should work for you. And I can tell you, it was blazingly fast: Seaside loaded in 5m45, and most of the time was spent compiling ... ;-) So try the mirror and the package out, send me your comments, we want to work on this to make Squeaksource a better experience for everybody. HOW TO USE from Pharo 1.3: - Get the redirection package from http://www.squeaksource.com/MonticelloRedirect - To load from the mirror instead of from Squeaksource, do-it of the following: MRManager redirectFrom: 'http://www.squeaksource.com/' to: 'http://www.dsal.cl/squeaksource/'. - To remove this redirection: MRManager removeFrom: 'http://www.squeaksource.com/'. - See comments of MRManager for more info. MRManager list can be useful at some times. - Only 2 classes, < 10 methods, not counting accessors. The trick is the use of MethodWrappers. - I did not test this in Squeak or other versions of Pharo. Feel free to try it out in your environment and send me patches if needed. - There is no UI, contributions are welcome!! DETAILS ON THE MIRROR - It's a full copy of Squeaksource, updated daily. - The mirror is read-only: if you want to make a commit you still have to do it in Squeaksource. This is to avoid all the complications of distributed writes. - Updates happen once a day, before midnight Chilean time. Updates take typically (up till now) 200 minutes (!), average download speed here is 200KB/s :-( - The Squeaksource team has been so kind as to provide a list of the packages that are in Squeaksource, refreshed daily and we pass this to wget (with some massaging of the data inbetween). - The Squeaksource list of packages is available here: http://scg.unibe.ch/download/SSProjectList/projectList.txt - The software that does the mirror is available here: https://github.com/vramiro/easy-wget-mirror MANY THANKS TO: - Daniel Galdames for doing the original mirroring tests - Victor Ramiro for taking Daniels' work and putting it in production - The Squeaksource team for providing the daily list of packages, especially Fabrizio Perin and Mircea Lungu - You for trying it out and telling us about it! ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile
