Running Squeak on Mac OS X fails due to damaged file.
by Henrik Aagaard 29 Sep '14

29 Sep '14

I’ve downloaded the Squeak-file from Squeak All-In-One several times, but all files fails to run due to damaged file. I’m running Mac OS X 10.9.4. Have anyone else experienced such problem and solved it?

Re: [Newbies] ProxyPipeLine terminates external command prematurely

Hi JohnReed, I am away and cannot be of much help right now, but I'm afraid that I may have given you bad advice in my last response. CommandShell does all the command parsing in Smalltalk, and it may not be smart enough to handle the complex parameters in the example you gave here. So it may be necessary to let the real Unix shell do the parsing, which is exactly what you were originally were trying to do - sorry. I'll try to give you a better answer in a day or so. Note, I have a hard time reading your examples in my mail system, so if you are able to post messages in plain text rather than html that would help me to understand what you are trying to do.

smalltalk 80 : book : adele goldberg : relevant for squeak 'mvc'?
by Mayuresh Kathe 09 Sep '14

09 Sep '14

hello, would the book "smalltalk 80: the language" by adele goldberg and david robson be still relevant with squeak using the 'mvc' environment? my first guess is "yes", but better to ask the experts, hence this email. :) thanks, ~mayuresh

(re)starting with squeak : soliciting book suggestions.
by Mayuresh Kathe 08 Sep '14

08 Sep '14

hello, i think i am now in a big mess. after mostly working with c-like languages, coming back to squeak feels very daunting. not that i am going to give up, but, would appreciate suggestions for a good book. searching around led me to http://www.informit.com/store/squeak-a-quick-trip-to-objectland-97802017311… can it be considered a good enough book for someone in my situation? thanks, ~mayuresh

cog support for linux framebuffer!
by Mayuresh Kathe 08 Sep '14

08 Sep '14

hello, would the new 'vm', i.e. cog, support using the linux framebuffer instead of relying on the x windowing system? please take a look at; http://wiki.squeak.org/squeak/3484 it has clear mention about the squeak on linux fb project. it would be nice to have squeak run atop the linux kernel directly on resource constrained hardware. best, ~mayuresh

status of the 'mvc' environment?
by Mayuresh Kathe 06 Sep '14

06 Sep '14

hello, i am returning to squeak after a gap of 14 years. back then, i used to work only within the 'mvc' environment as morphic hadn't taken off the way it has now. i still prefer the simplicity and lightness of the 'mvc' environment. at last use, the 'mvc' environment felt quite sluggish and crashed my squeak session multiple times. hope all is well! ~mayuresh ps: if boris gaertner is still around, could he please mail me off-list!
