[squeak-dev] Quick way to run out of memory
by Chris Cunningham 27 Jan '17

27 Jan '17

do: String new: -1 Yes, it doesn't really run out of memory, it's just a bug in ByteString>>basicNew: (ec == #'insufficient object memory' or: [ec == #'bad argument']) ifTrue: [^self handleFailingBasicNew: sizeRequested]. The VM gives us a nice error code telling us the arguement is bad, and then our code proceeds to assume it is out of memory instead. Bug verified in latest Trunk (as of now), and raw 5.1 image. A proposed fix is in the inbox: http://source.squeak.org/inbox/Kernel-cbc.1054.mcz <http://source.squeak.org/inbox/Kernel-maga.1054.mcz> This fix uses the old " self error: " pattern. If you'd prefer a new error for invalid argument, I would be happy to post a variant for that. Thanks, -cbc

I'm trying to help someone many miles away install CogSpur on a mac. I run Linux as a newb. On the mac they have run: |$ curl -L -o CogSpur.tgz https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/download/2016081… But when they try to unzip: | |$ tar -zxvf CogSpur.tgz tar: Unrecognized archive format tar: Error exit delayed from previous errors. Thanks. - Dan |

Hello, Maybe you know any hints on how Squeak's ODBC package could be improved to support unicode? Thank you, Vaidotas

steam controller and Etoys
by Vicki S 11 Jan '17

Hi. I tried signing up for the Squeakland mailing list but I'm not sure that worked. I was fiddling around with Etoys yesterday and remembered getting an Xbox 360 controller working with the joystick morph in Windows. So I tried out my Steam controller from Valve. I couldn't connect it to the morph but Windows 10 views it as a usb keyboard/mouse and it worked fine with the Etoys To Go app even without Steam running. Both the toggle and the left touch pad send arrow key input that the key press morph can capture. I am not sure if the controller functions in Windows without Steam installed but I wasn't up for the kerfuffle uninstalling Steam would cause just to find out. Unfortunately Steam isn't the kind of application young children should have installed but I thought it was cool that there's another input device out there that works well with Etoys. I tried out Ubuntu too but I haven't used the controller in Ubuntu for a while and I guess an update overwrote a configuration file because the wireless dongle wouldn't work. Plugging the controller in with a micro usb cord worked without Steam running but strangely lsusb still didn't detect it and I couldn't connect it to the joystick morph. Mouse and keyboard input was fine however. There may be an open source standalone Linux driver available but again I don't know if that is necessary. Of course to customize controller output applications must be launched from Steam. That works for Etoys as well. I am a hobbyist/enthusiast with an interest in educational software. Squeak has become my favourite environment for prototyping and experimenting and I much prefer Etoys to Scratch. Some of the issues I have with Etoys have been already been expressed by others so I am curious if any new versions are in the pipeline. Thanks Vicki

Squeakland mailing lists

I apologize in advance for not posting in the appropriate list but the Squeakland lists are not accessible right now. According to the irc chat log, someone from Sugarlabs asked about this a few weeks ago but I don't know if they got an answer through another avenue. I have noticed issues with the Squeakland website but I don't know if the website is in flux or if no one knows there are issues because the mailing list is down. I was able to sign up for an account but Etoys is no longer reading the Squeakland showcase directory. I was still able to upload a project through the website but the server didn't read any of the project information. The project is sitting in my account profile with no name or description. Timothy Falconer seems to have unsubscribed from the lists so I am unsure if he or someone else from Immuexa is maintaining the site. Can anyone point me in the right direction?
