Nabble down?
by Thiede, Christoph 10 Feb '20

10 Feb '20

Between 2020-02-09T23:29 and 2020-02-10T08:29 (UTC), the nabble forum<http://forum.world.st/Squeak-Dev-f45488.html> appears to have broken. I received emails from the list (such as: "[squeak-dev] The Inbox: Morphic-ct.1626.mcz"), but the forum does not list them. Could anyone check their servers? :-) Best, Christoph

Re: [squeak-dev] [Vm-dev] SqueakJS for Scratch (was: Questions on scratchJS:
by David T. Lewis 10 Feb '20

Hi Stefano, I think that your understanding is correct. SqueakJS stores files in an internal database, so the Scratch files that you saved do not appear directly on your PC. I do not know if it possible to copy those files to the file system on your PC, but hopefully someone on the squeak-dev mailing list will have an answer. Thanks for asking, Dave On Sun, Feb 09, 2020 at 09:51:25AM +0000, stefano federici wrote: > > >> you want to understand where the Scratch files are stored on your PC. > > Correct.

The file was not found. So, I guess projects are just saved in an internal SqueakJS DB? If it is so, this makes unfortunately ScratchJS useless for my purposes. And I have no sufficient javascript/smalltalk knowledge to try myself to change this behaviour (that I guess would possible in principle, as a lot of JS apps allow to save file locally). > > Cheers > Stefano > > > I am also CC'ing the squeak-dev mailing list where some of the real Scratch and SqueakJS experts reside. > > Thanks a lot Dave > > > I think that you are asking about running Scratch on Bert Freudenberg's SqueakJS, which is a modern Squeak virtual machine implemented entirely in JavaScript for HML5 > > Correct > > > If I understand your question correctly, you are asking about how to run Scratch on SqueakJS locally on your PC > > Yes. I partially solved the problem by downloading page https://squeak.js.org/run/ and by dragging my Scratch.image file into the page. ScratchJS runs apparently fine.

SqueakJS for Scratch (was: Questions on scratchJS:
by David T. Lewis 09 Feb '20

09 Feb '20

Hi Stefano, I am changing the subject line to "SqueakJS for Scratch" because google sends me somewhere else for "ScratchJS". I think that you are asking about running Scratch on Bert Freudenberg's SqueakJS, which is a modern Squeak virtual machine implemented entirely in JavaScript for HML5, rather than the traditional compiled virtual machines that run on operating systems such as Linux and Windows. If I understand your question correctly, you are asking about how to run Scratch on SqueakJS locally on your PC, and you want to understand where the Scratch files are stored on your PC. I do not have good answers to your questions but I am sure that others on this list can help. I am also CC'ing the squeak-dev mailing list where some of the real Scratch and SqueakJS experts reside. Here are some useful links for SqueakJS information: https://squeak.js.org/ http://try.squeak.org/ https://github.com/bertfreudenberg/SqueakJS And for Scratch: https://www.raspberrypi.org/blog/a-new-version-of-scratch-for-raspberry-pi-… https://www.raspberrypi.org/blog/test-tims-nuscratch-beta/ https://github.com/raspberrypi/scratch Dave On Sun, Feb 09, 2020 at 01:01:57AM +0000, stefano federici wrote: > > I managed running ScratchJS locally by saving the page https://squeak.js.org/run/ to my PC and the dragging my Scratch.image into the page. > > What I don't know is where the SqueakJS file system is stored.

Raspberry Pi 4 performance
by tim Rowledge 08 Feb '20

08 Feb '20

Just FYI - the Pi 4 is showing Squeak benchmarks around 3X faster than a Pi 3+, which raises it to a bit better than 25% the performance of my fast i7 iMac. considering that it costs less than the mouse attached to the iMac I think that makes it pretty good value. Oh, and this is running a very old 4.6 image with the benchmark suites loaded, so I hope a newer image might be at least a little faster. And it is running the 32bit cog VM since it has the vanilla 32bit Raspbian installed for now. We'll see what happens with a 64bit OS and cog sometime soon... tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim "Oh bother" said Pooh, as he reached for the reset button
