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.

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

nextPut: character toStream: stream ... code < 65535 ifTrue: [ ... should be code < 65536 ifTrue: [ because 3-byte encoding can fit 16 bits, which is range 0...65535 but not 0...65534 -- Best regards, Igor Stasenko.
