Yes, that one with ruby knight in the dungeon was nice. Because you both learn to program and you are implementing an AI. But it was too procedural and it was hard to modularize your code. Thatâs why Iâd like to be able to âenhance" your charter with methods. Uko > On 29 Feb 2016, at 20:25, stepharo <stepharo(a)free.fr> wrote: > > Let us know.

MemoryFileSystemFile>>#readStream forces String

by Udo Schneider

All, is there any reason why MemoryFileSystemFile>>#readStream forces it's content to a String (#aString)? readStream ^ ReadStream on: self bytes asString from: 1 to: size I'm parsing XML files from an in-memory ZIP Archive and had some real problem with non-ASCII characters.

Let us know. My plate is way too full I started to look at ruby framework where there a hero is in one dungeon (I do not remember which one it is) but yes I would like to have something for my sons to work on. Now I found that most of the time people were taught to conditional and this was boring. Because this is not what I want to teach.

Re: [Pharo-dev] Code Combat

I think that I was playing that for a few hours. This one may be interesting. One thing that really pisses me of with the coding games is that they usually work on reading and writing text which is a huge turn off for functional programming languages (and other ones too). Now code combat works on invoking methods (if I remember correctly), which is nice. Also I don't know how complicated the tasks are there, but usually in coding games I feel a lack of the support for organizing your code. For example I'd like to be able to add methods to my hero nested of writing numerous functions in a single file.

IIRC the default limit is 512Mb and that can be raised on the command line (or in an ini file ?). But I think that at least Windows xo has a 2gb preprocessor limit by default.

Re: [Pharo-dev] What is the limit of prespur VM memory under Windows?

by Eliot Miranda

Hi Vincent, yes I think you're right that the limit is 2Gb unless you change the system in I file. Google something like "more than 2gb under Windows" and IIRC you may be able to get 3gb. One thing is you're using a .ini setting. Perhaps that doesn't work. So try using the -memory argument on the command line. Another thing is that 2gb is 147,483,648 greater than 2,000,000,000 so you could try, say, 2,050,000,000. Finally you could start the image up on another IS and try and reduce its size, save and then start it back up on Windows. That's all I can think of right now. _,,,^..^,,,_ (phone) > On Feb 29, 2016, at 9:53 AM, Blondeau Vincent <vincent.blondeau(a)worldline.com> wrote: > > Hi, > > I am confronted with a memory issue under Windows. > I have an image of 745Mo with a Moose model, and I cannot instantiate a string of 30Mo: I get a OutOfMemoryException. > The theoretical limit is 2Go, isnât it? > > I have a prespur vm under a Windows 64 bits: > Smalltalk vm version: > 'NBCoInterpreter NativeBoost-CogPlugin-EstebanLorenzano.21 uuid: 4d9b9bdf-2dfa-4c0b-99eb-5b110dadc697 Dec 3 2015 > NBCogit NativeBoost-CogPlugin-EstebanLorenzano.21 uuid: 4d9b9bdf-2dfa-4c0b-99eb-5b110dadc697 Dec 3 2015 > https://github.com/pharo-project/pharo-vm.git Commit: 28d077d8df494ce050ca42c97c892471e8b8740c Date: 2015-10-16 12:02:43 +0200 By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #15019 > I set in Pharo.ini: AddressSpaceLimit=2000000000 > > What can I do to bypass the issue? > > > Thanks in advance, > Vincent > > > !!!************************************************************************************* > "Ce message et les piÃ¨ces jointes sont confidentiels et rÃ©servÃ©s Ã l'usage exclusif de ses destinataires.

No. The limit is supposed to be around 500 Mb on windows or 1 Gb for some specifically compiled VMs. 1 Gb VM may not start on windows, you may need to restart the computer before. To bypass the limit the best way is to use a spur VM honestly. Spur32VMs are limited to around 2.7Gb on Windows. 2016-02-29 18:53 GMT+01:00 Blondeau Vincent <vincent.blondeau(a)worldline.com> : > Hi, > > > > I am confronted with a memory issue under Windows. > > I have an image of 745Mo with a Moose model, and I cannot instantiate a string of 30Mo: I get a OutOfMemoryException. > > The theoretical limit is 2Go, isnât it? > > > > I have a prespur vm under a Windows 64 bits: > > Smalltalk vm version: > > 'NBCoInterpreter NativeBoost-CogPlugin-EstebanLorenzano.21 uuid: > 4d9b9bdf-2dfa-4c0b-99eb-5b110dadc697 Dec 3 2015 > > NBCogit NativeBoost-CogPlugin-EstebanLorenzano.21 uuid: > 4d9b9bdf-2dfa-4c0b-99eb-5b110dadc697 Dec 3 2015 > > https://github.com/pharo-project/pharo-vm.git Commit: > 28d077d8df494ce050ca42c97c892471e8b8740c Date: 2015-10-16 12:02:43 +0200 > By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #15019 > > I set in Pharo.ini: AddressSpaceLimit=2000000000 > > > > What can I do to bypass the issue? > > > > > > Thanks in advance, > > Vincent > > > > > !!!************************************************************************************* > "Ce message et les piÃ¨ces jointes sont confidentiels et rÃ©servÃ©s Ã l'usage > exclusif de ses destinataires.
