Installation on Ubuntu 15.10 (64 bits)
by Marion Noirbent April 7, 2016

April 7, 2016

Hi, I have installed Pharo on Ubuntu 15.10 (64 bits) with help of another user who ask me to report the troubles we have encountered. By following the instruction on the page http://pharo.org/gnu-linux-installation (and make "sudo apt-get install pharo-vm-core" then "sudo apt-get install pharo-launcher"), the file vm-display-X11 was missing. Then we have try "sudo apt-get install pharo-desktop pharo-launcher", we got the VM but without "PharoV40.sources", it was from 1 to 3 only. So we have donwload it from sources and fix it manually " wget -O- get.pharo.org/50+vm | bash sudo cp ~/pharo/pharo-vm/PharoV40.sources ../../share/pharo-vm/ sudo ln -s ../../share/pharo-vm/PharoV40.sources " Cordially, Marion Noirbent

[ANN] Pomodoro 1.6 for Pharo 5 + video
by Torsten Bergmann April 7, 2016

April 7, 2016

I did a new pass on the Pomodoro timer for Pharo 5: - settings with custom start value and custom colors - better resizing behavior of the morph - pause/continue - start/restart possibility - default colors aligned with Pharo scheme - pause state in Pomodoro instead of Morph - separate core and tests in own packages all included in a new release 1.6. Just use Spotter/Catalog to load. Enjoy the new video: http://youtu.be/voSUzOu5feU Bye T.

Highly depends on what kind of application you develop (installable rich client or web application for deployment on a user machine or a hosted system using a cloud provider) Some pointers when you deploy for a machine installation: http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/ https://pharo.fogbugz.com/?W78 http://pillarhub.pharocloud.com/hub/demarey/ez5m8nnaojww0rrnvnih9l4uy http://lists.gforge.inria.fr/pipermail/pharo-project/2010-February/021450.h… or hosted somewhere like on Pharocloud https://www.pharocloud.com/kb >How can i capture frame and packet in a network using pharo? you need something that intercepts network communication. https://www.wireshark.org comes to mind. You could possibly bind directly to libpcap (a portable C/C++ library for network traffic capture that is used by Wireshark) using Pharos Universal FFI. There is also WinPcap for Windows. Bye T.
