32 bits and 64 bits VM
by Hilaire Fernandes May 20, 2014

May 20, 2014

Yesterday my boss asked me to see DrGeo on his Ununtu 14.04LTS 64 bits machine. I could not get it working, 32 bits compatibility package to run 32bits application on 64bits system is gone, you have to find out manually the needed 32 bits libs and install it. Now I don't want to face this situation anymore, I want to provide with DrGeo a VM for each word size, compiled with not recent libc et al. and a working keypad. It is the bare minimum to not look ridiculous. By the way, the situation would have been equally ridiculous showing Pharo3. Now, I wonder, how is deal the 32bits/64bits situation on Windows and Mac OSX? Hilaire -- Dr. Geo http://drgeo.eu

And of course there is no need to have a lower number of screenshots now you can generate them from the image. Stephan

Versionner is even Coooler
by Sean P. DeNigris May 20, 2014

May 20, 2014

It is really a joy to start a project with Versionner... I used to delay creating a Metacello config as long as possible, and would try to add all the dependencies at once, often forgetting and chasing them down one at a time. Now these are all simple visual operations, so I create a config with the first dependency and add them as they come along, without interrupting my workflow too much. Thanks Christophe and other Versionner contributors :) ----- Cheers, Sean -- View this message in context: http://forum.world.st/Versionner-is-even-Coooler-tp4759583.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

blog post explaining the codecity visualization of pharo changes

Hi, I was asked several times for how the visualization from the Pharo 3.0 announcement was created. I now put together a blog post to explain it: http://www.humane-assessment.com/blog/communicating-changes-in-pharo-3-0 Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Hi, someone is working with Reef and is someone planning to migrate to Pharo 3? Is it working on Pharo 2 ? Thanks, p.s.: if nobody is migrating it maybe I can try it with Esteban instructions.

installing pharo 3.0 on Debian wheezy
by Ralph Boland May 20, 2014

May 20, 2014

I just tried installing pharo 3.0 on Linux Debian wheezy and failed. I first went to http://www.pharo-project.org/pharo-download and downloaded the Linux version. I unzipped it and attempted to run pharo. I got the error: ralph@m31:~/Pharo$ ./pharo /home/ralph/Pharo/bin/pharo: /lib/i386-linux-gnu/i686/cmov/libc.so.6: version `GLIBC_2.15' not found (required by /home/ralph/Pharo/bin/pharo) I assume the problem is Pharo is expecting me to have the 64 bit version of a library and i have the 32 bit version of the library but I am not sure of that. So I tried installing the Ubuntu version (from the same web page) following the instructions I ran: sudo add-apt-repository ppa:pharo/stable sudo apt-get update On the second command I got the errors: ... Hit ftp://ftp.debian.org stable/contrib Translation-en Hit ftp://ftp.debian.org stable/main Translation-en Hit ftp://ftp.debian.org stable/non-free Translation-en Err http://ppa.launchpad.net wheezy/main Sources 404 Not Found Err http://ppa.launchpad.net wheezy/main i386 Packages 404 Not Found Ign http://ppa.launchpad.net wheezy/main Translation-en_CA Ign http://ppa.launchpad.net wheezy/main Translation-en Fetched 129 kB in 4s (30.7 kB/s) W: Failed to fetch http://ppa.launchpad.net/pharo/stable/ubuntu/dists/wheezy/main/source/Sourc… 404 Not Found W: Failed to fetch http://ppa.launchpad.net/pharo/stable/ubuntu/dists/wheezy/main/binary-i386/… 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead. The solution is probably obvious to many of you. If I could be enlightened as to what to do that would be great. Thanks Ralph Boland

PPFlexiblePredicateSequenceParser
by Sean P. DeNigris May 19, 2014

May 19, 2014

I needed a parser that would match input against a predicate block, like PPPredicateSequenceParser, but for an unknown/variable length. For example, whereas for fixed-length matches you can already: parser := PPPredicateSequenceParser on: [ :value | value first isUppercase ] message: 'uppercase 3 letter words' size: 3. (parser parse: 'Abc') isPetitFailure not. Now you can: parser := PPFlexiblePredicateSequenceParser on: [ :value | Object canUnderstand: value asSymbol ] message: 'message to an object' while: [ :e | e ~= Character space ]. (parser parse: 'hash ijk') isPetitFailure not. (parser parse: '99 ijk') isPetitFailure. Is this generally useful enough to add to PetitParser? For now, you can get it via: Gofer it smalltalkhubUser: 'SeanDeNigris' project: 'SeansPlayground'; package: 'PPFlexiblePredicateSequenceParser'; load. ----- Cheers, Sean -- View this message in context: http://forum.world.st/PPFlexiblePredicateSequenceParser-tp4759616.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

200% CPU?
by Esteban A. Maringolo May 19, 2014

May 19, 2014

I am running a data migration, which involves some in-memory computation and heavy database i/o. Looking at how intensive this was the CPU use indicated by 'top' is 200% , I've seen percentages over 100% before, things like 107%... How is this possible? I'm running the pharo inside a VMWare machine with 2 cores. The good thing is that even with such high CPU, I forked the execution at userBackgroundPriority and the UI remained responsive. After this CPU intensive task took place, the vm got back to the "insidious" ~5% CPU idle state. :) Esteban A. Maringolo
