http://try.squeak.org/ is great but...

For a project I am involved in I am looking at alternatives for running applications in the web browser to avoid having to install stuff on a user's machine. So I took a look at http://try.squeak.org/ and think it is a fabulous resouce for our community. Unfortunately, I would not point out this page to people I want to get interested in Squeak. The reason for that is that they are likely to get frustrated by the differences in the Squeak 2.2 GUI in relation to "normal" OSes. The solution to this problem could be as simple as adding a paragraph between "Above you see..." and "Other Squeak image" explaining how to do stuff in Squeak 2.2 when you have one, two or three buttons on your mouse. It is important to explain how to get a world menu and how to "do it" and "print it". A child might play around until they find out these things on their own but most adults will give up after just a few seconds of things not working as they are used to. An alternative would be a video explaining the same thing and embeded right below the live SqueakJS. I would not put a link to a nice tutorial in another page because we want people to stay on the "try" page. -- Jecel

Hi all, Are Mantis password reset emails getting through for other people? I just tried to send one to myself, and it seems not to have made it through. Tony

Nasty side effect
by Tobias Pape 23 Feb '17

23 Feb '17

Hi all here's a nasty side effect of our way of ensuring that the heartbeat-thread thing works. https://github.com/dalehenrich/metacello-work/issues/427#issuecomment-28191… TL;DR: (1) Run squeak w/ superuser/root rights creates the 'package-cache' directory as root (2) Installing something with monticello then _SILENTLY_ fails Both is bad. So, (1) is hard to fix. I would have said, hey, if we are root, just _don't_ run squeak but just create the heartbeat files. But that makes no sense when we actually want to run squeak as root. SUGGESTION: - Do not ship heartbeat vm in the all in one[1] - Ship the heartbeat vm only in system packages[2] - Fix handling File-open failures. I'm onto (2), and frankly, I was surprised to learn that: squeak-dir$ mkdir foo squeak-dir$ chmod -w foo and then (FileDirectory default / 'foo') newFileNamed: 'bar'. "==> nil" this Must Not happen. To many to-dos in one mail, I know :( Best regards -Tobias [1]: Yes, I know, performance is bad then, but the user experience is badder [sic]. That is a hard-to-cope-with tradeoff. [2]: Wich means, that we eventually, finally, have to package debs and rpms, I'd say.
