Re: [Pharo-project] Fwd: could you sign the pharo license?

by StÃ©phane Ducasse

now the questions are - is it really that difficult to agree for a project on a given simple license such as MIT? - I also hate licenses since they polute our lives but I just don't care and signed MIT - should we accept this kind of license (of course it is compatible with MIT) but this looks a door open to the mess. I'm not sure squeakers realized that after all the effort of yohsiki to get SqueakEtoys clean 3.11 could be WTFPL because keith commit on it. I'm quite convinced that they will boycott such a code.

Keith, I'll have a look. My interest will probably be limited to Pharo; the 3.9 image is one of line of images I built to keep an eye on Squeak. I ended up looking at it today only because I knew I had the SSL sockets working somewhere. I'm surprised how easy it was to miss that the newer attempts were incomplete. That said, I think I now know what to look for, and where to go for reference of what needs to be present. Thanks, Bill Wilhelm K.

Damien, Thanks for making the new image. Is there a way to tell the image to display walkbacks instead of going straight into the debugger? The new image seemed a nice excuse to play catch-up, which means getting a few things loaded. Seaside - I recalled discussion of it, and quckly stumbled onto a closed bug report about ScriptLoader new universalInstaller universe install: 'Seaside'. That appears to work. The cryptography team's work will be important. This gets weird fast. I have a 3.9 image where it is installed correctly and works; I have very little idea how that happened. My subsequent installation attempts appear not to be complete. SqueakMap appears to be going away in Pharo. Replacing it appear to be Installer, ScriptLoader, and maybe some of your tools to build the developer images. Is there a clear correct way to install packages now? Put another way, if I make an attempt to sort out installing the cryptography and SSL classes in Pharo, how would recommend attacking it? Pharo is not even in beta yet, so no complaints, but I am missing something on how to go from a new core image to something that is ready for use. Bill Wilhelm K.
