I think even alone you be non-linear. And the secret is: feedback loops. So imagine we implement something that makes it easier to work. (better browser, refactoring tools...). Then *using these* will make it easier to build new tools and abstractions... that make us more priductive.... Improving a system allows you do do things *faster*, and even, at some point, do things that where impossible without the improvement. (regardless how much time and intelligence you have). *That* is non-linear progress. Making the system better so you can make the system better more easily.

I even spent time learning what is 'super-linear' means. :) You're right that if taking a single individual, and his contribution to Pharo , it is of course always linear. But if you take a sum of those contributions by whole community, then you can easily see that the rate of improvement in different (or same) area can easily surpass the linear speed. -- Best regards, Igor Stasenko.

Re: [Pharo-project] how to load rb in pharo 1.4?

by Tudor Girba

Thanks. My question was about RB because I need it separately from the user interface. But, I got it under control now :) Cheers, Doru On Tue, Feb 14, 2012 at 4:17 AM, Jimmie Houchin <jlhouchin(a)gmail.com> wrote: > On 2/13/2012 2:11 PM, Tudor Girba wrote: >> >> Hi, >> >> I lost track of the latests developments around RB.

Re: [Pharo-project] Are Objects really hard?

Ahh, I am so upset with this thread. It's not the content that upsets me, but the fact that my pointing out that Pharo has a super-linear evolution went unnoticed due to all the trolling activity. So, let me mention it again "One should not presume much about Pharo because its evolution super-linear, and we all know how poor we are at estimating such super-linear models." :) Cheers, Doru

Pharo is open-source project. This means that people, who contributing to it, is its customers, and solving own problems, not yours and not some virtual-customer's problems. Now if this project doesn't solves your problem, it doesn't means that this cannot be changed of that there someone who not willing to change or doing everything to prevent that. You just approach with wrong perspective. And your sentence about losing lots of money because you put bet on Pharo looks just silly. You were not participating, not reporting any problems, you basically not exist.

Maybe the problem is not there, but in other arguments you passing. And, i recommend you to use ConfigurationOfNativeBoost from NBInstaller, but not latest packages directly, since Javier put a lot of changes lately and some parts might not work properly. > > My image craches.
