We will move just due to this to another issue tracker eventually, but it will be quite some effort. I do not yet know when we will have the time and energy to do that. Marcus

Rule engine

Hello, If anyone is working in a rule engine we could merge efforts because I have implemented one (or something like that) for a project. Cheers, HernÃ¡n

(either OSLinuxUbuntu or just OSProcess: PipeableOSProcess command: 'gnome-terminal &'. ) it should open the terminal on top (though i don't know hw it behaves without a window-manager) run tmux (or screen) with mutt inside. detach tmux when done with email. close the terminal, which brings you back to pharo. that way the terminal is not using up resources when it's not running, but mutt keeps running, and can be accessed when you need it. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

It is possible :) I work with DNA sequences, there could be millions of common SNPs in a genome.
