Re: [Pharo-project] Any theme or settings that will speed up a Pharo 1.3 image?

what you can try is to use lower color depth for the display. try switching to 1-bit mode.. which is black/white :) On 20 March 2012 16:02, Camillo Bruni <camillobruni(a)gmail.com> wrote: > > On 2012-03-20, at 14:49, Stefan Marr wrote: > >> >> On 20 Mar 2012, at 14:03, Camillo Bruni wrote: >> >>> >>> On 2012-03-19, at 20:54, Marcus Denker wrote: >>>>> You used your own images for Pinocchio, or was Pinocchio just fast enough for the standard images? >>>>> >>>> Pinnocio can't run the image... it's ("just ;-)") a compiler from smalltalk to binary code... the .exe then boostraps an image, >>>> but there is no support to persist that (nor support for all the primitives.. and no GC other than Boehm). >>> >>> indeed ;) we tricked around the image :D >>> >>> stefan, do you rely on a visual interface?

Yes, that seems to be a CogVM problem.

[Pharo-project] Make arduino work on linux with cog vm

by Mariano Vicente

Hi Everybody. I'm just started with Pharo, and Arduino. And i like to comunicate both. I instaled the package sent by Ricardo Moran in a Pharo 1.4 with the Cogvm from the Jenkins server, but i can't make the serials port works. The Arduino board, i have, is connected to usb, wich ubuntu detects as /dev/ttyACM0. I tried opening serial ports, like this: sp:=SerialPort new. sp openPort: '/dev/ttyACM0'. sp openPort: 'ttyACM0'. sp openPort: 'ACM0'. sp openPort: '/ttyACM0'. But all they fail with a error saying ""Cannot open..." After that, i have also, tried this: (1 to: 10000) select:[:port | [SerialPort new openPort:port;close. true] on:Error do: [false]] and had a empty collection. And also tried giving full permissions to the port and executed the vm sudoed... Are serial ports working on ubuntu?. Do i have to download a special vm?. (I would like to do a demo of arduino on monday, at work, and i would like to do in Pharo.) Cheers, Mariano
