But this change would be much more intrusive (change primitives...), and not really compatible with established practices where alpha channel is interpreted as opcity level, not as transparency level ( http://en.wikipedia.org/wiki/RGBA_color_space) I think we can forget this part of the proposition which is too much Smalltalk-centric.

Problem with wrapping text in pdf documentation
by kilon alios Dec. 19, 2013

Dec. 19, 2013

Take a look here https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… code is cut out and does not wrap. Looks it exceeds its boundaries. Maybe some sort of bug ?

Re: [Pharo-dev] UDP Broadcast message

This is not a âuser featureâ. And even though it is "the right thing" for lots of situations, your network is also very likely to not do the right thing with broadcast packets. Etsy decided on using bittorrent protocol to update their production servers indexes, because they found it too difficult to get their network to do the right thing. They found that their switches were basically livelocked while dealing with broadcast packets. http://codeascraft.com/2012/01/23/solr-bittorrent-index-replication/ If you want the broadcast to travel a little further, the routers need to be configured not to drop the packets.

[image: Inline images 1] my image is full with tons of such processes.. why not using morph stepping to refresh inspector instead of forking process and forget to terminate it properly? -- Best regards, Igor Stasenko.

UDP Broadcast message
by jannik.laval Dec. 19, 2013

Dec. 19, 2013

Hi guys, In Pharo, it is not possible to catch a UDP Broadcast message. Catching a UDP message is easy and works fine, but not when it is broadcasted (strange !) Does someone try that ? Could someone propose a solution ? Maybe with OSProcess or NativeBoost ? Thank you a lot. Jannik
