Re: [Pharo-users] What oo/modelling books/articles do we recommend these days?

Looking a bit further - Chapter 3 of: http://sdmeta.gforge.inria.fr/FreeBooks/STandOO/Smalltalk-and-OO.pdf <http://sdmeta.gforge.inria.fr/FreeBooks/STandOO/Smalltalk-and-OO.pdf> (Smalltalk and Object Orientation - Hunt) gets me a bit closer, but still thinking Iâve seen better somewhere.

Has anyone else got any thoughts? I checked out the Larman book - but it seems very process heavy (probably excellent for a full blown course), while Iâm looking for something a bit lighter weight to guide students on the right way of thinking/approaching the little problems in Exercism. Wasnât there something that encouraged you to underline the nouns and circle the verbs and then start to identify objects and responsibilities? Its that kind of thing I am starting to see as the weak point in people approaching problems.

Hi Nick, You could make a âspecial editionâ for the Pharo Newsletter.. that is, a newsletter that is just about one project. We plan to do one about PharoThings, too. (else the normal monthly newsletter will have your announcement, I will send you a preview before sending) Marcus. > On 25 Mar 2019, at 12:11, Nick Papoylias <npapoylias(a)gmail.com> wrote: > > I will be showcasing the features of Lands <https://npapoylias.gitlab.io/lands-project/>, > in espresso-sized form for the next couple of > months on twitter ;) > > Please support the project by making some noise ! > > On related news: I am joining the LIG lab atÂ <https://www.liglab.fr/en> > Grenoble <https://www.liglab.fr/en> to work on DSLs for the Linux kernel, > so stay tuned ! > > Best, > > Nick, > >
