>but he replied to me and I forwarded to you. Yes, but we have no admin access as he wrote he had given us. I think I answered to this again and got no response (cant remember the details). Nonetheless the project is "read write" anyway. Unfortunately without admin access I'm not able to delete the wrong ConfigurationOfAutomaticMethodCategorizer that I once uploaded by accident.

[Pharo-project] Compiling for iOS?
by David Li Dec. 9, 2010

Dec. 9, 2010

Hi, Sorry to ask such dumb question. I have just download the source from http://squeakvm.org/svn/squeak/trunk and found the Xcode project in the iOS directory is setup to compile for OS X. I tried to search this list for answer but didn't find any question/answer related to this. So my question is that: 1. Am I downloading the iOS source from the right place? 2. If correct, how do I get a xcode project to compile for iOS? Thanks. David Li

[Pharo-project] System Change Notification Broken
by Lukas Renggli Dec. 9, 2010

Dec. 9, 2010

I wanted to draw the attention to http://code.google.com/p/pharo/issues/detail?id=3396 The system change notification service is kind of critical for everything. Any idea why it doesn't work anymore in the latest system? Lukas -- Lukas Renggli www.lukas-renggli.ch

[Pharo-project] Just another struggling newbie
by Chip Nowacek Dec. 9, 2010

Dec. 9, 2010

Hello everyone, While I should have introduced myself before I ran into trouble, it is trouble that has brought me here. I guess I'm glad something provided the excuse to meet you. First, a short introduction... I'm really new to Smalltalk. Kent Beck said it's a good choice for my project. Technically, I come from the database architecture world - though I am more entrepreneur now than techie. I'm starting up a new company and Kent suggested building a prototype myself instead of bringing someone else in - so here I am. I'm trying to move from Squeak because Pharo feels a little more developer oriented. We'll see how it goes. To the matter: I don't understand why I can't accept a change to my comment in one of my classes. When I try to accept in the OB Package Browser, about a dozen calls in, #Utility is being sent #changeStamp and doesn't understand it. I am in the midst of sorting through the stack trying to figure out what happened. As you might imagine, it's a little discouraging for such a basic function to blow up. What makes it worse, I'm probably the cause of the problem - I just don't know what I screwed up. I am working in Pharo 1.1.1 and have loaded Magma and O2 per: DEVImageWorkspaces openExternalProjectWorkspace I created a package for my stuff according to that which I have read so far. Maybe I did that correctly. My classes are in a category within that package. With introductions complete, I don't intend my future posts to be so long-winded. Thanks for whatever patience you've been able to afford me. Chip

[Pharo-project] [Progress Report] Zinc HTTP Components
by Sven Van Caekenberghe Dec. 9, 2010

Dec. 9, 2010

This is another progress report on the Zinc HTTP Components project. - I finally integrated support for UTF-8 encoding and decoding of text entities (ZnStringEntity, ZnUTF8Encoder). - Internally, all input and output is done through binary streams (but character streams are still supported for debugging). - A number of units tests were added. - Class comments were improved. - Lots of small fixes and new features. The overall structure of the project was improved by moving old code into a separate MC package, renaming categories and renaming some classes. The external documentation was updated http://homepage.mac.com/svc/Zinc-HTTP-Components I would still love more users/testers. The code works well enough for day to day use and the feature set is reasonably complete now. Sven PS: Please check the SqueakSource history for a all the details.

[Pharo-project] Why is FileStream writing almost an order of a magnitude slower than reading ?
by Sven Van Caekenberghe Dec. 9, 2010

Dec. 9, 2010

Related to the Matrix CSV input/output optimalization quest, I was puzzled why writing seemed so much slower than reading. Here is a simple example: [ FileStream fileNamed: '/tmp/numbers.txt' do: [ :stream | 100000 timesRepeat: [ stream print: 100 atRandom; space ] ] ] timeToRun. 1558 [ FileStream fileNamed: '/tmp/numbers.txt' do: [ :stream | 100000 timesRepeat: [ Integer readFrom: stream. stream peekFor: $ ] ] ] timeToRun. 183 [ FileStream fileNamed: '/tmp/numbers.txt' do: [ :stream | 100000 timesRepeat: [ stream nextPut: ($a to: $z) atRandom; space ] ] ] timeToRun. 1705 [ FileStream fileNamed: '/tmp/numbers.txt' do: [ :stream | 100000 timesRepeat: [ stream next. stream peekFor: $ ] ] ] timeToRun. 47 Clearly, the writing is close to an order of magnitude slower than reading. This was on Pharo 1.1 with Cog, but I double-checked with Pharo 1.2 and Squeak 4.1. On my machine (Mac Book Pro), this is what another dynamic language does: > (time (with-output-to-file (out "/tmp/numbers.txt") (loop repeat 100000 do (format out "~d " (random 100))))) Timing the evaluation of (WITH-OUTPUT-TO-FILE (OUT "/tmp/numbers.txt") (LOOP REPEAT 100000 DO (FORMAT OUT "~d " (RANDOM 100)))) User time = 0.413 System time = 0.002 Elapsed time = 0.401 Allocation = 2502320 bytes 0 Page faults Calls to %EVAL 1700063 NIL > (time (with-open-file (in "/tmp/numbers.txt") (loop repeat 100000 do (read in)))) Timing the evaluation of (WITH-OPEN-FILE (IN "/tmp/numbers.txt") (LOOP REPEAT 100000 DO (READ IN))) User time = 0.328 System time = 0.001 Elapsed time = 0.315 Allocation = 2500764 bytes 0 Page faults Calls to %EVAL 1400056 NIL So Pharo Smalltalk clearly matches the read/parse speed, which is great, but fails at simple writing. Maybe I am doing something wrong here (I know these are MultiByteFileSteams), but I fail to see what. Something with buffering/flushing ? Anybody any idea ? Sven
