Raspberry Pi boot directly to eToys?
by Charles Schultz 17 Nov '13

17 Nov '13

Good day, First, let me say how I impressed with the various developement teams involved (RPi, Squeak, eToys, Scratch). You all are doing amazing work! I have been googling and am attempting to learn how to boot the Raspberry Pi directly into eToys just like the option for booting directly into Scratch. Surely there is a relatively easy way to do this, but since eToys is not yet deployed on the stock Raspbian image, it does not yet look like it has the official support on the RPi install team. I am very thankful that installing eToys is as easy as "apt-get install etoys" - that is so totally awesome! Now, how to boot directly into eToys? As an aside, any idea why eToys is filed under "non-free" extensions for RPi? -- Charles Schultz

Etoys Installer corrupts Firefox..
by UniHigh Computer Support 30 Oct '13

30 Oct '13

Dear Dev list: The eToys installer assumes that there is a plugins directory already present in FireFox so when it attempts to install the NPSqueak.dll it ends up creating a plugin FILE (with the contents of NPSqueak.dll) instead of directory, which will munge things for other installers (Microsoft Lync) that later attempt to install their plugin file into the Mozilla plugins directory (which is a file created by eToys). We have removed it from our base install due to complications resulting from this error. However, the plugin itself really needs to be re-written as the NPAPI is being phased out of multiple browsers: http://techcrunch.com/2013/09/23/say-goodbye-to-npapi/ Also, your contact page on your website (http://www.squeakland.org/contact/) throws the following error: 500 Servlet Exception java.lang.SecurityException: Access to default session denied at javax.mail.Session.getDefaultInstance(Session.java:320) at com.immuexa.gumbo.Utils.sendMail(Utils.java:1118) at com.immuexa.gumbo.web.WebContactSendAction.perform(WebContactSendAction.java:84) at org.apache.struts.action.ActionServlet.processActionPerform(ActionServlet.java:1787) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1586) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:510) at javax.servlet.http.HttpServlet.service(HttpServlet.java:165) at javax.servlet.http.HttpServlet.service(HttpServlet.java:103) at com.caucho.server.dispatch.ServletFilterChain.doFilter(ServletFilterChain.java:113) at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:177) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:221) at com.caucho.server.hmux.HmuxRequest.handleRequest(HmuxRequest.java:392) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:331) at com.caucho.util.ThreadPool.runTasks(ThreadPool.java:464) at com.caucho.util.ThreadPool.run(ThreadPool.java:408) at java.lang.Thread.run(Thread.java:619) Resin-3.0.8 (built Tue, 08 Jun 2004 02:25:40 PDT) M@ Matt Childress unihighhelp(a)illinois.edu Uni High IT Guy University Laboratory High School @ The University of Illinois

Ah, that's on the old wiki: http://oldwiki.squeakland.org/display/sq/How+to+translate+Projects Would be great if someone could make a more thorough step-by-step guide, like the one for the help system: http://oldwiki.squeakland.org/display/sq/How+to+translate+the+Quick+Guides However, these are different in that a separate project is used per language and loaded on demand, whereas for the home-screen (and projects in general) all the translations live in a single project together. > The first step in this translation would be to generate a list of > strings so that I can pass them on for translation. Yes. Unfortunately our in-project translation is not set up for gettext, and the home screen is just a project as far as the system is concerned. Once you have changed the home screen project, you need to switch to the hidden "Unnamed1" project (via ctrl-shift-w) and save the etoys image. - Bert -

how to hide ALL connectors to/from a specific node in the Connectors package?
by Lawson English 22 Sep '13

22 Sep '13

I'll try again: I have 19 Connectors nodes showing in my project. There are 19 x 18 connectors -a fully connected graph. I want to be able to easily tell all connectors to hide using Etoys scripting. I already know how to do this with Squeak, but it isn't obvious at all how to make it work with etoys, despite the existence of a scripting option "tellAllIncomingConnections" and "tellAllOutgoingConnections" I can't figure it out. I've dropped down into the System browser and looked at the Smalltalk code for #tellAllIncomingConnections: aMessageSelector and #tellAllOutgoingConnections: aMessageSelector "Send the given message selector to all the players of the receiver's costume's outgoing connections" self costume outgoingConnections do: [:m | m playerRepresented ifNotNilDo: [:p | p performScriptIfCan: aMessageSelector]] I've even tried putting ^#hide into the script. Is this aspect of Connectors + Etoys broken or am I missing something? I can specify a SPECIFIC Connector to hide, but I have potentially 19 x 18 or even 256 x 255 of them to work with, so obviously this isn't an option. Do I have to go with my incredibly cumbersome code I worked out in my Squeak youtube tutorials and stick that into a script, instead? Thanks.

Thanks for the response. However, I assume that "tile hide" really means a tile for "ConnectorInstance hide" also, it doens't work. I only manage to hide the specific connector. Yes they are all siblings. I can't find an AllPlayers tool mentioned in the online manual. Perhaps this is the holdup? I'm using the Mac version. Thanks again.

FW: [squeakland] how to hide ALL connectors to/from a specific node in the Connectors package?
by Harness, Kathleen 15 Sep '13

Hi Lawson, This solution is from Lenny Pitt who has helped Etoyillinois a lot! Regards, Kathleen ________________________________________ From: Pitt, Leonard B Sent: Saturday, September 14, 2013 4:58 PM To: Harness, Kathleen Subject: Re: [squeakland] how to hide ALL connectors to/from a specific node in the Connectors package? I'm not on squeakland / Etoys mailing list, but perhaps you can pass along the solution: All pins should be siblings of each other. All connectors should be siblings of each other. Now, create a script called "hideme" for a connector, which has only the tile "hide". So, if a pin tells all incoming connectors to execute the script "hideme", they will hide, and similarly, if a pin tells all outgoing connectors to execute the script "hideme", they all will hide. Now, to make ALL the connectors hide at once, we need to tell all pins to tell all incoming and outgoing connectors to execute the script hideme. To do this, create the following script: A script for a pin called "hideeveryone" which has in it only the two commands tell all incoming connectors execute script hideme. tell all outgoing connectors execute script hideme Now, just have any pin send to all siblings "hideeveryone". As a result, all pins will execute the script "hideeveryone". Which means all will send to all their incoming and outgoing connectors the command to execute the hideme script. Note that this is overkill - we don't need to tell both incoming and outgoing connectors to execute the hideme script, since every connector is an incoming and outgoing from someone. So the script "hideeveryone" needs to only have one of the two lines in it.

Is there a way to tell the length of a sound?
by Steve Thomas 14 Sep '13

14 Sep '13

Folks, Mike Lee recorded a video with some folks in Zambia for the Lubutto project where "Dr. Enesto," "Dr. David," and "Chairman Moses" share their most recent work with Mike: http://youtu.be/lGO0OaRYWJM Among other things they asked two questions: 1. How to show a progress bar when a sound is playing to "know when its going to finish or how far it is"? 2. Can they pause and then continue a sound. One way that could solve this is if I knew the length of a sound. I could also use this to coordinate sounds for animations/movies. So: 1. Is there a way to tell the length of a sound? - Can you think of a better way to solve the problem? 2. I don't know of any scripting tiles to do this, but is there a way using Squeak? Thanks, Stephen

question about connectors and scripting in general
by Lawson English 14 Sep '13

14 Sep '13

Hi. I'm trying to use the Connectors package within EToys to generate a complicated movie. First step: create a graph of nodes with connections between them (done -or at least, doable). Second step: manipulate connectors with scripts from within EToys. and... nothing. I've located the script "tell all outgoing connectors" associated with a single node. I've created a script with the code ^self hide and associated it with the "tell all outgoing connectors" and "tell all incoming connectors" scripts and attempted to fire it once. Nothing happens. Ok, so I tried a different script: hide. ^ self. Nothing happens. I know how to use Connectors directly within Squeak. I've made youtube tutorials on how to figure out how to do arbitrary stuff with Connectors at teh Squeak level using the debugging tools. I'm stymied at step 2 using EToys. :-/ Suggestions? Thanks.
