I do what I can. I should say that sometimes I'm puzzled by the lack of vision of certain people. Now I hope that people understand why we are doing pharo: to create a nice ecosystem where people can build their own life and make a living with Pharo.

Re: [Pharo-dev] NativeBoost class>>#isEnabled ?

by Esteban Lorenzano

Nope, it will not be restored. NativeBoost is gone. In exchange, you will have the new FFI-NB who should always be present (so you do not need to ask). So, depend on the point of view: NativeBoost isEnabled can answer always true (in case you ask for FFI presence), or always false (in case you actually want the NB plugin). What you can do is to remove the NB tests from your test list, I do the same in our buildsâ¦ and this is just a temporal solution, because I will remove NB and ASMJIT completely next week :) Esteban > On 28 Dec 2015, at 14:28, Alexandre Bergel <alexandre.bergel(a)me.com> wrote: > > Hi Esteban, > > The following expression "NativeBoost isEnabledâ raises an error in a Spur image.

This will be viewable through a chosen perspective and there may be more than one tech level perspective. A strong perspective of avatars in 2D or 3D graphics and using robotics to control avatars and NPCs in this space seems important to my vision of this.

Hi Esteban, The following expression "NativeBoost isEnabledâ raises an error in a Spur image. Would it be difficult to restore the original semantics of this method? Our 3d effort is currently stuck in a pre-spur image.

Re: [Pharo-dev] [Pharo-users] Transcendental #new (was Re: why Pillar)

by Johan Fabry

Robert, by talking about âa knee-jerk reactionâ and âa lack of knowledgeâ you are being rude to us. Please donât do that. In our mails we have been courteous and avoided using such hurtful expressions. Also, there is a difference between lack of knowledge and lack of time. I am only human with limited time and matters which are more pressing than the discussion you insist on holding. Consider it from my point of view: I am not forcing you to think about design decisions of the JIT of the domain-specific language for robotics that am I building.

That's all. Which is exactly what I did, I posted how it is related and still caught a knee-jerk reaction. I am drawing a line. I will continue to reference religious and scriptural meta-models. There is coherent thought in these models and they are familiar to the majority of the people on the planet, the average person, even if the intellectuals fail to resonate with it. This familiarity makes it a good model for the average person to interact. Seems to be a lack of knowledge on the side of the intellectuals.
