Raspberry Pi 4

Did anybody not see this? https://www.raspberrypi.org/products/raspberry-pi-4-model-b/ It's made a bit of a splash today. I think it will make a pretty neat Squeak machine, especially for any sort of MC server setup etc. I'm anticipating about a doubling of performance over the 3B+ which would make for quite nice benchmarks. Dual 4K display capability should come in handy too. Now to find someone to fund the work to do the 64bit ARM Cog.. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: IBLU: Ignore Basic Laws of Universe

I run Pharo on Pi since a few years and it has a decent performance and is stable for serving stuff. See my medium article [1] and video [2] from 2015. I also was also able to run the old Squeak Comanche Wiki on it and use it for personal stuff. For Pharo the current status on PI is described here: http://lists.pharo.org/pipermail/pharo-dev_lists.pharo.org/2019-June/275553… >Now to find someone to fund the work to do the 64bit ARM Cog. Yes - an 64bit ARM Cog for OpenSmalltalk VM would be really great. It could also help pushing Smalltalk IoT platforms like http://www.pharoiot.org Maybe a project on a crowdfunding plattform could help and show if there is enough interest... Thx T.

SqueakSSLTest failure/errors on macOS?

Hi, I have one failure in #testFacebookAPI and three errors in #testSSLSockets, #testSocketAccept, and #testSocketAccept in SqueakSSLTest on macOS Mojave 10.14.5. I tried the latest trunk images 18618 with the release VMs and the latest VMs on bintray, both 32bit and 64bit: Croquet Closure Cog[Spur] VM [CoInterpreterPrimitives VMMaker.oscog-eem.2530] 5.0.201906130203 Mac OS X built on Jun 13 2019 02:12:03 GMT Compiler: 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42) platform sources revision VM: 201906130203 https://github.com/OpenSmalltalk/opensmalltalk-vm.git Date: Wed Jun 12 19:03:53 2019 CommitHash: a85579a1 Plugins: 201906130203 https://github.com/OpenSmalltalk/opensmalltalk-vm.git CoInterpreter VMMaker.oscog-eem.2530 uuid: 4d90ede0-0700-4d15-8173-2aaf2360b7d1 Jun 13 2019 StackToRegisterMappingCogit VMMaker.oscog-eem.2530 uuid: 4d90ede0-0700-4d15-8173-2aaf2360b7d1 Jun 13 2019 I would like to know if other Mac users can confirm these. If yes, does anyone know anything about these problems? I assume the tests on macOS are not run during the trunk build, right? Cheers, Bernhard
