authenticating Squeak to a proxy
by wgsilkie＠ihug.co.nz 04 Apr '08

Hello, I am new to Squeak (but not OO programming), and reading the "Squeak by Example" book, but I can't figure out how to get Squeak to use a proxy that requires authentication. When at home, this is not a problem, but at my school, I can only access the Internet through an HTTP proxy, and it requires that each student enter his or her username and password. I've found where in Squeak I need to tell it what port to use, and the server name, but there's nothing there for a username or passkey. Is there a way to tell Squeak to authenticate itself as a particular user? Thanks, Aidan

Magma - freeing memory, and preloading index
by stan shepherd 04 Apr '08

Hi, I've currently got 2 Million objects in a MagmaCollection. My memory use is 300MB. I thought by doing maCollection add: entry. magmaSession stubOut: rating. and periodically garbageCollecting, the entries would effectively be flushed to disk and release memory. Am I misunderstanding? Is there another way to do this? Also, I suspect loading is being slowed by dynamically creating the 2 indexes (indices?). Is there a way to pre-create these, in order, before adding the entries? ...Stan -- View this message in context: http://www.nabble.com/Magma---freeing-memory%2C-and-preloading-index-tp1647… Sent from the Squeak - Beginners mailing list archive at Nabble.com.

SBE and Squeak versions out-of-sync?
by David Finlayson 01 Apr '08

01 Apr '08

I'm on vacation and learning Smalltalk is how I'm spending my evenings (family is young and goes to bed early). I downloaded a copy of Squeak by Example (Version 2008-3-10) and the latest squeak for OS X: Squeak3.9-7067mac vm 3.8.18beta1U With the recommended dev-image: sq3.9.1-7075dev08.03.1 Considering the date of the most recent update to the book, I was surprised (and very confused by) a number of major differences between the Squeak image described in the book and the one on my computer. I've waisted a lot of my spare time trying to figure out what the heck is going on. The main problems are differences between the World menu (completely reorganized, apparently), expert vs novice mode (no "Do it" in novice mode but this was the default mode) and what looks like some major changes in the System Browser (for example, the need for packages before defining a class, the lack of a second window for editing class comments, etc. Right now, I can't define a new method as described in Section 2.2 the method template doesn't show up when I click on -- all -- in the protocols pane. Doubtless it is user error, but I'd like to get back on track (maybe I downloaded something I shouldn't have?). Any suggestions? I checked the on-line errata for the book and it does not mention any of these interface changes I'm seeing. Thought that I would post here rather than waist more time flailing around. Sorry so long winded. David
