TSUG on Meetup.com
by Chris Cunnington 30 Apr '14

30 Apr '14

http://www.meetup.com/Toronto-Smalltalk-User-Group/events/179013662/ Adam Spitz had the good idea of trying to broaden our Toronto Smalltalk Users Group message by getting a meetup.com site. Seems in the past few years programmers have been using it more and more. Adam went to a Clojure meetup and people were aghast the TSUG existed at all. So, kudos to Adam for trying a new way to promote Smalltalk. See y'all in TO on the 12 May. Chris

unnecessary mcz downloads
by Eliot Miranda 29 Apr '14

29 Apr '14

Hi All, I just followed a common enough workflow to commit partial changes: 1. in an image with some in-progress changes, implement a fix that I want to commit, excluding the in-progress changes 2. take a copy of the image, revert the in-progress changes, commit the fix 3. in the original image, merge with the committed package The strange thing is that while the step in 2. writes the package to the package-cache before uploading it, the step in 3. downloads the package again instead of simply using the identical copy in the package-cache. Anyone know why? Is this easy to fix? (This in a Squeak 4.5 trunk image) -- best, Eliot

Help needed to compile a fresh Mac Carbon VM
by David T. Lewis 26 Apr '14

26 Apr '14

VM hackers and Mac enthusiasts, we need your help. Here is your chance to earn big karma points, along with the grateful admiration of the your peers. What we need: A freshly compiled Mac Carbon VM, just like the Squeak 4.2.5beta1U VM on http://squeakvm.org/mac, but updated to use current VM sources, and to include CameraPlugin and ScratchPlugin. Why we need it: See below. We have a GSOC project mentor who needs to do work on a Mac, who needs to run an image format 6502 (pre-closure) image, and is running into problems related to the outdated Mac VM. We need an update to the Mac VM so that the GSOC project can proceed, and to prevent problems like this for other Mac users who need to be able to run older images (Etoys, Scratch, etc). http://www.google-melange.com/gsoc/project/details/google/gsoc2014/positive… If you have the ability to compile a Mac Carbon VM and make it available to the community, then please speak up. We need your help. (Cross posted to several lists, but discussion should go to vm-dev if possible) Thanks in advance, Dave On Thu, Apr 24, 2014 at 07:55:33PM -0400, Steve Thomas wrote: > David, > > I really appreciate the help and prompt reply. > > I checked and it does work under a previous version of OSX (10.7.2) > > Cheers, > Stephen > > > On Thu, Apr 24, 2014 at 5:01 PM, David T.

VM camera plugin on the Pi
by Herbert König 25 Apr '14

25 Apr '14

Hi, with the Squeak VM that comes with the Pi there is a so.CameraPlugin which I assume is the scratch camera plugin Tim mentioned earlier. Can this be used from Squeak and what would I have to load to use it? The (maybe) wrong colours are not a problem for me. BTW I managed to use the camera via the OSProcess plugin. Cheers, Herbert

SMServer beta update
by Chris Cunnington 25 Apr '14

25 Apr '14

I've been experimenting with SqueakMap, so I made a new map with one package. These instructions show how to configure your SqueakMap Catalog to download that map and load SMServer. [1] Chris [1] 1. In the image directory delete the "sm" folder or remove it from that directory. 2. In "SMSqueakMap class initialize" change to: #('box4.squeak.org:9971/seaside/smserver') 3. execute SMSqueakMap initialize 4. execute SMSqueakMap clear 5. open SqueakMap Catalog and press Update 6. Right click on left pane and select "Clear all filters" 7. Select SMServer and press Install 8. It will ask for a username and password (admin/seaside). It will have two errors; press Proceed through both 9. execute WAKom startOn: 9971 10. Go to http://localhost:9971/seaside/smserver

Unload environments from 4.5
by Herbert König 25 Apr '14

25 Apr '14

Hi, I wanted to try Environments from 4.5 to see if this makes project save work again. I got the attached MNU. Is this futile as Environments are entangled very deep in the guts of Squeak or are Environments intended to be unloadable? Cheers Herbert

XDisplayControlPlugin
by Chris Muller 25 Apr '14

25 Apr '14

Hi Dave, I am interested in playing around with #forkSqueak, et al. Do you know where I can find a precompiled XDisplayControlPlugin? It wanted it even when I tried to use forkHeadlessSqueakAndDoThenQuit. I want to try this: | a | a := Array new: 1. OSProcess thisOSProcess forkHeadlessSqueakAndDoThenQuit: [ a at: 1 put: 'one']. (Delay forSeconds: 5) wait. a "#('one')? or #(nil)?" Thanks.

Spur performance report...
by Eliot Miranda 23 Apr '14

23 Apr '14

Hi All, I should write a blog post on this, but I can't wait... In recent days I've written a script to build a Cog VMMaker image from Squeak 4.5. See http://www.squeakvm.org/svn/squeak/branches/Cog/image. This has allowed me to run the current Cog VM against Spur side-to-side. To build a Cog VMMaker image on my 2.2GHz Intel Core i7 MacBook Pro using the current Cog VM takes about 2 and a half minutes: McStalker.image$ time oscfvm CogVMMaker.image BuildSqueak45Image.st real 2m30.671s user 2m15.683s sys 0m5.283s To build the equivalent image using Spur takes about 1 and a half minutes: McStalker.image$ time spurcfvm CogVMMaker-spur.image BuildSqueak45Image.st real 1m34.943s user 1m23.666s sys 0m6.810s Comparing: 94.943 - 150.671 / 150.671 * 100 -36.99 83.666 - 135.681 / 135.681 * 100 -38.34 150.671 / 94.943 1.59 135.681 / 83.666 1.62 that's about a -37% speedup, or 1.6x faster. -- best, Eliot

Monticello Whitewash...
by Eliot Miranda 23 Apr '14

23 Apr '14

ugh... after opening a multi-window browser on the Spur classes in the automatically-created VMMaker image I notice once again that Monticello doesn't preserve class organization order on load. grr.... Anyone up to fixing this? -- best, Eliot
