SSH server in Squeak
by Aditya Siram 08 May '08

08 May '08

Hi all, I was wondering how to get an SSH server working in Squeak. I was told that this service has been implemented but I can't find any documentation. I originally posted to the Seaside mailing list but this is probably a better forum for it. Thanks ...

The Weekly Squeak Summary No. 18: Mar 23 - May 3, 2008
by Michael Haupt 05 May '08

05 May '08

Dear Squeakers, welcome to this edition of The WeeklySqueakSummary, an irregular traffic-dependent report on what's going on in the world of Squeak based on the WeeklySqueak blog. This is, by the way, the first edition that is also sent to the AIDA mailing list - thanks for the invitation! Highlights of the past weeks: Hilaire Fernandes is writing a series of blog entries that introduce Squeak specifically to educators [10]. Material of this kind is extremely welcome and much needed! Two announcements have come true: first, Gilad Bracha's talk on Newspeak, which he gave at HPI in Potsdam, is now available online [7] (some trouble with viewing have been reported, but with a recent player and no over-zealous firewall, viewing should be no problem). Second, the Seaside tutorial hosted at HPI has been turned into a book, which is finally available (the first book on Seaside, yay, and please forgive the author his personal pride) [8]. Finally, there's three technical items. Squeak is now available on yet another platform, namely the Syllable OS [4]. At the time of posting, only headless images were supported, but it ran Seaside. JavaConnect and JNIPort [12] are two projects that support Smalltalk/Java interoperability in very elegant ways. While they are currently available only on VisualWorks (and, as for JNIPort, Dolphin), they set standards in terms of language/platform connectivity. SqueakFS [13] allows for browsing the Squeak image as a mounted file system (on Mac OS X and Linux, using the FUSE library). The top-level directory supports looking at the image along one of three axes: along the class hierarchy, grouped by class category, and as a flat space containing all classes. At present, it's read-only, but future extensions are already being planned. The past weeks' news items: [1] Seaside startup snapped up http://news.squeak.org/2008/03/28/seaside-startup-snapped-up/ [2] What's the difference? http://news.squeak.org/2008/03/31/whats-the-difference/ [3] The Year of Smalltalk http://news.squeak.org/2008/04/02/the-year-of-smalltalk/ [4] Squeak ported to Syllable http://news.squeak.org/2008/04/07/squeak-ported-to-syllable/ [5] Free Smalltalk books http://news.squeak.org/2008/04/10/free-smalltalk-books/ [6] Waveplace in the US Virgin Islands http://news.squeak.org/2008/04/16/waveplace/ [7] Video of Newspeak lecture now available http://news.squeak.org/2008/04/19/video-of-newspeak-lecture-now-available/ [8] "An Introduction to Seaside" now published http://news.squeak.org/2008/04/21/an-introduction-to-seaside-now-published/ [9] Squeak Project in Google Summer of Code 2008 http://news.squeak.org/2008/04/25/squeak-summer-of-code-2008/ [10] Using Squeak in Education http://news.squeak.org/2008/04/26/squeak-in-education/ [11] New Dabble DB Demo Debuts http://news.squeak.org/2008/04/28/new-dabble-db-demo-debuts/ [12] Using Smalltalk with Java: JavaConnect and JNIPort http://news.squeak.org/2008/04/30/using-smalltalk-with-java-javaconnect-and… [13] Squeak and the filesystem http://news.squeak.org/2008/05/02/squeak-and-the-filesystem/ You can find this and much more on The WeeklySqueak blog, the newsblog dedicated to the world of Squeak:http://news.squeak.org/ Subscribe to the WeeklySqueak RSS feed: http://news.squeak.org/feed/ Happy squeaking, Michael

Best way to view many classes
by gruntfuttuck 04 May '08

04 May '08

Hi, More than a few times now I have played around with squeak. I keep leaving and recently I have realized why: I find it easier to follow code with in files than with a code browser. I can scroll a file fast and even I have 10 files open I still find it easer. So my question is: what is the best way to follow and reference multiple classes in multiple packages? I know I could open more than one class browsers but that seems cumbersome. -- View this message in context: http://www.nabble.com/Best-way-to-view-many-classes-tp17034832p17034832.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Linux locks up when handling large data sets
by squeak414＠free.fr 04 May '08

04 May '08

Hi, I've been testing Squeak's ability to handle large amounts of data. This snippet: testArrayFilling | startTime endTime iArray jArray kArray | iArray := Array ofSize: 100. 1 to: 100 do: [:i | jArray := Array ofSize: 1000. 1 to: 1000 do: [:j | startTime := Time millisecondClockValue. kArray := Array ofSize: 1000. 1 to: 1000 do: [:k | kArray at: k put: Object new]. jArray at: j put: kArray. endTime := Time millisecondClockValue. Transcript cr; show: i asString , ',' , j asString , ' ' , (endTime - startTime) asFloat asString. startTime := Time millisecondClockValue]. iArray at: i put: jArray]. Transcript cr; show: 'Finished' creates about 5 million objects , then the image freezes. When I run on the same machine under Windows, it happily continues until the short of memory warning ( about 70 Million objects in my case). The VM is 3.7 in both cases, the image Damien's 3.9 development image. There seem to be a number of Unix lockup issues. Is a later (or earlier) VM likely to fix this please? Thanks, ...Stan

How to increase size of Transcript
by Milan Zimmermann 03 May '08

03 May '08

When writing to Transcript using Transcript show:, after certain amount is put on the Transcript, the screen gets cleaned, keeping only about 10K of text. Is there a way to increase the amount of text Transcript keeps before cleaning? Thanks Milan PS: I tried to inspect the Transcript model (TranscriptStream) and modify the readLimit and writeLimit but it did not help.

What is the current state of namespaces in Squeak? Is there a programming convention to prevent name clashes? Thanks.
