Arduino package extra files

by Bernat Romagosa

Hi list, After successfully installing the Arduino package, I noticed this Getting Started text: *After installing the Arduino packages by evaluating...* * * * ConfigurationOfArduino load.* * * *...you'll need a couple extra support files in order to be able to upload programs to your Arduino board. You can download them from here:* * * * http://www.mediafire.com/?1rep41uygl4rpf1* * * *Extract the contents of that file in the same directory where you have your Pharo image.* But the mediafire link is broken. Where can I get the extra support files? Thanks! Bernat. -- Bernat Romagosa.

Re: [Pharo-users] Pharo 2.0 with RFBServer with -headless

by Srikumar Karaikudi Subramanian

Following up .. Almost as soon as I'd written this up, I realized I hadn't tried one thing ... and that worked :) 1. I took the base image from get.pharo.org that I was using on the server, 2. Launched pharo using Pharo2.0.app on that image (with GUI), 3. Installed RFB using the "Gofer" part of the command in my previous mail, 4. Started the RFB server by running the RFB server part of the script, 5. Did "save and quit", 6. Uploaded the new image to my server, 7. Ran in it headless mode. Now it works! ... but I'm still at a loss to explain why this worked but the following steps done entirely on the server via scripts didn't - 1. Save and quit after just installing RFB (the "Gofer" part). 2. Save and quit after starting the RFB server. 3. Run the resultant image in -headless mode. It looks like I had to get the image to be modified by Pharo2.0.app in order for this to work. Hope this helps someone else struggling with the same thing.

Pharo 2.0 with RFBServer with -headless

by Srikumar Karaikudi Subramanian

Hi, Since this is my first post, I'd first like to say Pharo rocks! After quite a bit of search for a server-side programming environment that I can live with, I landed on Pharo/Zinc+family and went "this is it!" for my project which is like a wiki for music notation. I'm trying to setup a pharo+zinc server with RFB installed on a VPS so I can access it through VNC ("Chicken of the VNC" on MacOS 10.8.5). I'm only get a static image of the pharo environment when I connect and I don't get any interactivity at all. One other poster [1] who mentioned this also posted that the problem was solved with a later version of squeak, which I didn't have any luck with since I don't have X configured on my server. Much appreciate any tips. I got pharo from get.pharo.org and cloned the image using "save". I run the following script on the cloned image with the "-headless" flag (I tried with and without the flag.) "----begin code---" Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfRFB'; load. (Smalltalk at: #ConfigurationOfRFB) load. (RFBServer current) allowEmptyPasswords: false; allowRemoteConnections: false; allowInteractiveConnections: true; allowZRLE: true; setFullPassword: 'my password'; start: 0. [1 hour asDelay wait] repeat. "----end code----" One other point - if I save an image after loading the RFB package (using "Smalltalk snapshot: true andQuit: true.") and then launch with a script that only starts the server, I get a static black screen instead and not even the static image. So I don't understand why there should be a behaviour difference between the two as well. Regards to all, -Kumar [1] http://groups.yahoo.com/neo/groups/squeak/conversations/topics/141662

Re: [Pharo-users] Reset Spec #openWorldWithSpec:

by Benjamin

euuuuh Basically what is done when you open a spec as world is that the background color changed, all the morph are closed, and the spec is specified to take all the space. So to revert it, I think you *only* need to close the spec morph, set the background color to white, and voilÃ Ben On 24 Oct 2013, at 18:51, btc(a)openinworld.com wrote: > > Message #openWorldWithSpec: sets a Spec entity to take up the whole World.

Has anyone tried?

To use PetitParser for XSD Parsing and generation of Smalltalk code based on this Parsing? Regards Friedrich
