Re: [Pharo-users] Voyage: Circular references

by Esteban Lorenzano

btw the configuration of voyage is outdated in the mongotalk driver (another thing I need to update, he) you might want to try manually updating the mongotalk packages. cheers, Esteban On Jun 11, 2013, at 1:39 PM, Bernat Romagosa <tibabenfortlapalanca(a)gmail.com> wrote: > Hi Esteban! > > Thanks a lot, I tried your code and it's working for me, so the problem must be somewhere else. > > I set up a logger in VOMongoSerializer >> #serialize:description:using: and I can confirm it keeps jumping back and forth between two related objects, but I don't really know why... > > #new is overriden in my model classes, could this have any impact? > > > > 2013/6/11 Esteban Lorenzano <estebanlm(a)gmail.com> > Hi, > > sorry...

Re: [Pharo-users] minimal headless pharo2 for CentOS

by Mariano Martinez Peck

Regarding the VM, in most 64bits Linux, you have to install some additional 32 bits libs. If you get a message like this: [marianopeck@myserver pharoVM]$ ./pharo could not find display driver vm-display-X11; either: - check that /opt/pharo/pharoVM//vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Aborted (core dumped) Then you can try to execute something like: sudo yum install mesa-libGL-devel-9.0-0.7.el6.i686 libX11-devel.i686 libXmu.i686 I do have VirtualBox running headless with Pharo running headless as well in a CentOS 6.4. To execute Pharo headless: ./pharo -vm-sound-null -vm-display-null myImage.image Cheers, On Tue, Jun 11, 2013 at 8:26 AM, Pavel Krivanek <pavel.krivanek(a)gmail.com>wrote: > Hi Robert, > > look at Pharo Kernel 2.0 image with Gofer > > https://ci.inria.fr/pharo-contribution/view/Pharo-Kernel-2.0/job/PharoKerne… > There is a version with preloaded basic Seaside too > > https://ci.inria.fr/pharo-contribution/view/Pharo-Kernel-2.0/job/PharoKerne… > > Cheers, > -- Pavel > > On Tue, Jun 11, 2013 at 12:14 PM, LogiqueWerks <grshiplett(a)gmail.com>wrote: > >> re: headless Pharo 2.0 >> >> I just finished building gst on a tiny VPS site, but I would rather use >> pharo ...

Hi Esteban! Thanks a lot, I tried your code and it's working for me, so the problem must be somewhere else.

Hi Robert, look at Pharo Kernel 2.0 image with Gofer https://ci.inria.fr/pharo-contribution/view/Pharo-Kernel-2.0/job/PharoKerne… There is a version with preloaded basic Seaside too https://ci.inria.fr/pharo-contribution/view/Pharo-Kernel-2.0/job/PharoKerne… Cheers, -- Pavel On Tue, Jun 11, 2013 at 12:14 PM, LogiqueWerks <grshiplett(a)gmail.com> wrote: > re: headless Pharo 2.0 > > I just finished building gst on a tiny VPS site, but I would rather use > pharo ...

Hi, sorry... I has been running like hell last two weeks. I posted a reply http://stackoverflow.com/questions/17039914/how-to-persist-graphs-presentin… but sadly no good news... I don't know where is your error. Probably a problem in your configuration. I have in my TODO list to write a comprehensive documentation for voyage, but I'm not sure when I will have the time to finish it...

Re: [Pharo-users] minimal headless pharo2 for CentOS

Robert, What size are you aiming for ? A normal Pharo image needs between 50 and 100 Mb, with everything included. Not much in my book, are there such small VPS machines today ? I run 6 such Images/VM pairs on a AWS EC2 micro instances (~600Mb RAM). Linode starts at 1Gb ...

minimal headless pharo2 for CentOS

by LogiqueWerks

re: headless Pharo 2.0 I just finished building gst on a tiny VPS site, but I would rather use pharo ... I can get some tips from pharo --help in my SSH console but I have a big dev CentOS here in VirtualBox in which to experiment in headless builds if set on the right track ... Does anyone have a tip on starting with a Pharo 2.0 core ? I just need sockets, minimal HTTP and StdOut - I don't think I want Seaside on this tiny install ... but I would rather be using an HTTP server in Pharo than in Ruby or Python ... I have come to loathe Lighttpd and nginx config silliness ... but I could fallback to Ruby Sinatra or merb while I wait ... (the poor-man's Smalltalk ;-) Or should I be looking to strip down a VW image and wait for Pharo 3 ? I am scripting with Rebol 2 for now while I wait for rebol3 or Red ... thanks, Robert in a small Atlantic town Canada PS last night I could not see how to run St/X without X to see what mem footprint I would face ! -- View this message in context: http://forum.world.st/minimal-headless-pharo2-for-CentOS-tp4692753.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

ZdcSecurePOP3Client is normally in your image, else it can be found in Zodiac-Extra (http://mc.stfx.eu/Zodiac) and should work for GMail, for example: ZdcSecurePOP3Client retrieveMessagesFromGMailAccount: '<your-name>@gmail.com' password: '<your-password>' limit: 5.

Test.eml is a message that I sent to myself, containing an image. I just saved it from Apple Mail as raw text. The result should be something like the following screenshot: Note the nesting of mime parts.
