To help find existing ones it might be helpful to explain that some migrated to smalltalkhub and ss3, and that that might not be obvious from looking at the squeaksource page. I'm happy to see both Pharo and Squeak mentioned. The beta tag on smalltalkhub doesn't make much sense. It is heavily used in production with a few hundred CI jobs, lots of which are critical to the development of Pharo itself. This week there were 15 new projects and 12 users added. And yes, is also missing functionality that is unlikely to be added and the web ui has serious issues. Stephan

You can play with these options and look if the result looks better. For exampe, if you enable the hintMetrics, the rendering result looks almost like your pango/cairo example. But the characters looks like they are squeezed (vertical direction). And if you disable the LoadNoHint/NoAutoHinting, the result looks (I think) exactly like th pango example. But I don't know if this are the correct settings. Whoever wrote this functions may had a reason to choose this setting. (if you want to play with these options, you have to flush Athens/Cairos cache.

I am not going into the benefits of SCTP itself but this protocol is the base for âSIGTRANâ and also for backend systems in LTE networks.

I think there should be two separate items: * The SocketPlugin should know the SCTP network type and operations like socket(2)/connect(2)/bind(2) should work. The beauty of the BSD socket design is that the VM only needs to know how to deal with a filedescriptor. * There should be an additional plugin to bind the advanced sctp primitives. This could work on OSX, FreeBSD and Linux. > 4. Decline to use it.

I am using a piece of C application that handles SCTP/SIGTRAN and provides a TCP/IP relay for Pharo.

Stream Control Transmission Protocol

by Ben Coman

Going through old issues, I see one [1] regarding adding SCTP [2] support. I've not heard of this protocol before. What are its benefits and use case for Pharo/Squeak ? Regarding our resource constraints, modularisation goal and ongoing support, what is our strategy for this? 1. Integrate for Pharo 5? 2. Integrate into VM as plugin and have as external Configuration for image? (btw, remind me if a Configuration can also add a VM plugin?) 3. Continue to leave it for later. 4. Decline to use it. Holger, What application are you using this for, and how are you managing to work with this at the moment?
