Like Miguel said you should use the image from the website. As you could see on the website a second edition of the book is in the make. I would advize you to start with the current book. It gets you going in using smalltalk and pharo. After that the second edition will be available. Quite some things will have changed then but nothing fundamental regarding smalltalk. It could be nice for you to follow the evolution if you start from the first image and you get the feel how it gets better. You will be one of the guys that have a fresh look on all of this. That is one thing we all are missing because we are working quite some time with it and we are blind to certain things. So don't hesitat to ask questions or the complain about things you think are stupid :) Norbert

IMHO the only fix is to use the image from the website. There is a reason for this image. If you are a newbie than everything that does not work like it is written in the book is distracting. Giving advize to load a browser that is neither in the book nor is it used by a lot of people is definitely not a good idea. Norbert

It's built primarily for graph drawing, but there is a MOScatterplotLayout which allows one to draw plots. http://www.moosetechnology.org/tools/mondrian Just a simple example (do not hesitate to ask for clarification) points := OrderedCollection new. {5. 5. 3. 10. 15. 8} pairsDo: [ :x :y | points add: (Point x: x y: y) ].

I'm not exactly a seasoned Pharo user, but I think you can file in code from your .changes file by opening it (as you open any other file from within Pharo) from a fresh/clean image. --Aidan

What to do after vm crash?

by DougEdmunds

XP SP3 box, Pharo.exe v 4.0.2.0 Image: PharoCore-1.2 I've been using this image for several days. This time when I opened it, it immediately crashed. I've tried starting it several times, including after a reboot, with the same results. I get a popup entitled "Fatal VM error', with some numeric details. When I click ok, it writes a crash.dmp file and closes. 1) Is there a way to to recover the image, if I start with a clean image? 2) Is there anyone who wants a copy of the crash.dmp report? It's about 100 lines long, and I could post it or email a copy to someone.

Yes they are asked often but mind not. The Pharo By Example has a Pharo image prepared for it that was used when the book was written. www.pharobyexample.org to the right, section Download Pharo: # Pharo By Example image (recommended for use with the book) Cheers -- Miguel CobÃ¡ http://twitter.com/MiguelCobaMtz http://miguel.leugim.com.mx

Package browser?

by Rob Vens

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.
