[Pharo-project] jpg woes

by Brian Mason

I am trying to take an image off the new and save it to a file. This is what I have so far: (FileStream newFileNamed: 'test.jpg') nextPutAll: ('http://freetalklive.com/images/amondson.jpg' asUrl retrieveContents) getContentFromStream; close The image exists, is found, and the file is written. There is something wrong with the format of the local jpg. I would appreciate some guidance. "You can have everything you want if you just help enough other people get what they want." - Zig Zigglar

Re: [Pharo-project] Show stopper network bug on Windows

by Schwab,Wilhelm K

Again, I *think* the problem is too much code removed, and failure to protect with #useOldNetwork. It blows up on IPv4; it happens both on Windows and Linux. If anyone has counter examples or can otherwise show me wrong, please set me straight.

This is way better than having a methods carrying a multi-kilobyte long bytearray, but still not perfect.

+100000000000000 to Esteban's comments on the Dolphin IDE - it's slick in ways that are not visually obvious.
