Re: [Pharo-project] Auto create new and initialize methods for new class?

by StÃ©phane Ducasse

why do you need an automatic new method? Because by default new invoke initialize and it works well.

fabrizio we should really include some of the moose extensions to pharo. Could you take the lead on that? Did you try gather:?

Re: [Pharo-project] donating money

I would not put in a separate line for institutions. Companies, organizations, institutions, research labs and universities should all be able to choose one of the 3 levels, depending on how important Pharo is for them or on how large their use of Pharo is. A small organization could be a gold member if they live or die with Pharo, a multinational could be a bronze member if they only have a small team using Pharo occasionally. Yes I such got two hours discussion with lawyers and this is the point > - The goodies/extras at the different levels seem about right. > - The license concept has a wrong, even dangerous name, maybe we could call it End User Support Contract ? This is not the same. The idea is that for some lab this is not possible to donate money nor be part of the consortium but they can pay a license for a product and we should be able to hand them a bill. > - The general day price of 800 sounds a bit high, 600 (75/h) seems a bit more acceptable (but even that is high in an international contest).

Oh yes! > It will be a challenge to properly represent this on the website. :) the real challenge will be to be able to hire somebody for a year when people do not pay all at the same time. Because if we want to pay some smart guys like igor in france we have to get a visa (and all the rest). We will encourage people two pay early and if they can two years in advance. In addition my team will probably put 20 K on the table and we will probably ask for extra months for igor to sustain the bootstrap I will do an official announce in a couple of days.

Done right, what a config loads can be 100% static and repeatable. If you load a literal version (e.g. '1.4'), which loads literal versions of dependent projects (which they should unless there is a reason not to, e.g. a loose dependency like Seaside on OB), which load literal versions all the way down, it will do the same thing today, tomorrow, and ten years from now. The only hill to climb now is getting the word out about Metacello conventions/best practices.
