Re: Scratch resources for adults?

My advice would be to use NuScratch instead. That is, instead of clicking on ‘Scratch 3’ in the menu, go for plain ‘Scratch ‘ with no number. NuScratch is the original version of Scratch (lots of messages in this forum a out all the fun I had in making it practical for the Pi) as written in Smalltal...

Re: RP4(4gb) with M.2

For those who might want to try out a clean solution, I've rewritten and better integrated the code to support power management, shutdown and reboot on Geekwire's X856 and X735 add on boards to provide a better desktop-like experience. Excellent. I have an older X820 currently attached to 3B+ and s...

Re: Raspberry Pi for saving marriage.

Remember also that you should not run multiple copies of Marriage at the same time unless you are in one of the jurisdictions where local law supersedes the supplier terms and conditions. Claiming to be a sailor and therefore allowed a copy in every port does not meet these conditions. (True story -...

Re: Raspberry Pi for saving marriage.

Which version of the Marriage application are you running? Old versions had a bug where you couldn’t quit them even if they locked up or started leaking resources etc - at least not without the rather brutal ‘kill -9’ approach. There could also be issues in some of the more puritanical OS’s where yo...

Re: Future of raspberry pi - software related

You might be right about the tablet. Since they are landfill within a couple years after purchase, there must be millions of them waiting to be fished out of the bin and repurposed as a display devices for a Pi. Really? I hope that’s not actually the case. I have an original iPad and a 6 y.o. iPad ...

Re: History of Linux on ARM?

Not precisely Linux on ARM but for a while in the mid/late 80s I had an Acorn R260. Preferred the A540 for RISC OS though. And obviously not Linux but Helios for the Active Book machines, so still a *nix. Then in the mid 90s in California I had a Corel Netwinder or two, which I think actually was Li...

Dunno. That’s one of the options I might try. Another, possibility simpler to do, is to add it to the built-in gpio server I added way back.

Re: Scratch 1.4 Squeak is almost out of memory. Already compressed sounds

Yeah, I can’t do any magic to make sound samples smaller but I probably can do some to make a way to play sounds from named files instead of samples loaded in the project file.
Failing that I can certainly make a way to do it in straight Smalltalk. Like I said, an interesting problem.

If you’d like to post some descriptions of how you connected the buttons, which gpio pins you used etc I might be able to do something for you. It’s an interesting problem.
Perhaps zip the Scratch project file too and upload it?

Re: Scratch 1.4 Squeak is almost out of memory. Already compressed sounds

Well if your music samples are actulaly typically 9000kb - ie 9Mb, then 100 of them is almost the entirety of a Pi's memory. You can't be surprised if Scratch - or any program - complains about getting short of memory when loaded up that much! Your problem is that the way Scratch handles sounds is t...

I can fix the “won’t work with a space in the name” problem for you; Unix has never liked this since it is how it separates parts of the command, so you have to use a little tweak to convince it.

The running of Scratch with the -vm display=none is tested and works.
Running something on start up is documented and even discussed in the front page blog as of this week. Time to have fun experimenting.
