Re: [Pharo-dev] Anonymous classes should be browseable

by Eliot Miranda

Hi HernÃ n, I'm curious. How are the anonymous behaviours found so they can be shown in the browser?

Re: [Pharo-dev] pharo-os : a fantasy!

by Mayuresh Kathe

pharonos sounds very interesting, almost the same as what i had in mind. but ofcourse for the difference in building _that_ object layer between the linux kernel and pharo environment. that object layer (built using shell scripts) would add in an enormous amount of flexibility. another approach that might be considered would be to simply tap into the variables exposed by "sysctl" and maintain a state system within pharo and do the read/write to the kernel via sysctl directly. ~mayuresh On Mon, Jan 26, 2015 at 04:00:28PM +0100, Torsten Bergmann wrote: > I also play with Mike's PharoNOS these days and ask myself why > not do the major part in Pharo itself... > > Check the "OS-Unix" and "OS-Linux-Ubuntu" project > on STHub. > > Bye > T. > >

pharo-os : a fantasy!

I also play with Mike's PharoNOS these days and ask myself why not do the major part in Pharo itself... Check the "OS-Unix" and "OS-Linux-Ubuntu" project on STHub. Bye T.

Installing Pharo on Ubuntu

by J.F. Rick

I have a new computer and installed Ubuntu 14.10 on it. When I tried to install Pharo using the PPA instructions, it failed. I get the following message when executing "sudo apt-get update": W: Failed to fetch http://ppa.launchpad.net/pharo/stable/ubuntu/dists/utopic/main/binary-amd64… 404 Not Found W: Failed to fetch http://ppa.launchpad.net/pharo/stable/ubuntu/dists/utopic/main/binary-i386/… 404 Not Found I was able to get Pharo running with the Zeroconf script, but I thought I'd report that the standard thing didn't work. Is it just that a binary doesn't yet exist for 14.10. Cheers, Jeff -- Jochen "Jeff" Rick, Ph.D. http://www.je77.com/ Skype ID: jochenrick
