[Pharo-users] Re: Pharo and Virtual Realitity

[askoh]

Hi:

I installed Pharo and enter the following in workspace.

Author uniqueInstance fullName: 'VRIDE User'.

(ZnServer on: 1701)
bindingAddress: NetNameResolver localHostAddress;
delegate: ZnReadEvalPrintDelegate new;
start;
yourself

PharoVRIDE open

I don't understand the following instructions in GitHub page:

Now open PharoVRIDE. Right into the first scene, you will see a field asking
for the IP address of your Pharo server. It must be as follows:

http://:/repl

If you are running on localhost just as shown in the previous script, press
the Enter button to proceed. Otherwise, you must specify an address.

Finally, put on your VR headset, and try some stuff!

Please advise.
Thanks,
Aik-Siong Koh

Hi:

I am preparing to port StCAD from VisualWorks to Pharo. Please advise how
this can be done most efficiently. I am not familiar with Pharo GUI

StCAD uses Jun which uses OpenGL and GLUT. I am open to using newer graphics

Re: [Pharo-users] StCAD is open source

[askoh]

Hi:

I have been careful to separate the GUI, Geometry, Multibody Dynamics and
Math. Only the GUI would need customization for Pharo. The others use pretty
generic Smalltalk. I suspect the GUI bits from Jun4Pharo, Woden and Croquet
should be sufficient for StCAD port. StCAD uses a bit of Jun and a bit of
GF/ST and a bit of Business Graphics Kit. I am willing to help anyone
starting the port. It can be the basis of a CAD system.

[Pharo-users] StCAD is open source

[askoh]

Hi:

I have just open source StCAD (MIT license) which has the code for freeCAD.
http://askoh.com/stcad
Although written in VisualWorks Smalltalk, I hope Pharo users will port it
in part or whole.

All the best,
Aik-Siong Koh

What is 'StCAD'?

'StCAD' is a basic 3D CAD framework in Smalltalk (VisualWorks 8.x). It
extends
the GF/ST 2D drawing framework into 3D. It also include 'StCAD-Geo' which is
the 3D geometric domain, 'StCAD-Math' which provides the mathematical
support
for 3D CAD and motion simulation computations, and 'StCAD-Doc' which is a
simple word processor. 'StCAD-Math' is also suitable for engineering,
scientific and business computing. The parcels are open source using MIT
License. Users can use these parcels with other private software to create
3D
applications like motion simulation, finite element analysis, CAD,
scientific
visualization, etc.

'StCAD' allows users to create and manipulate assemblies, which are
collections of 3D parts. The parts are 3D solids, which can be connected by
joints, constraints, contacts, actuators, springs, dampers or forces. The
parts and connections define the structure or mechanism that the assembly is
meant to represent. Animation is possible, if the user can provide time
series
of position and orientation data for the parts.

Users can also obtain output data in the form of plots and tables. XY plots
can be zoomed and set to equal scales. Data series available include linear
and angular displacements, velocities, accelerations and other user
generated
data.

'StCAD' has been used to create a freeware called 'freeCAD' which is a 3D
CAD
with Motion Simulation. For more information visit:

Great answer. Spoken like a wise man.

I want a web app to fill paper forms - like income tax forms say. The forms
are scanned or input into the app. The developer provides the logic
connecting the input and output fields of the forms. The users then use the
app to fill their own forms, print them or send them electronically. Can
Smalltalk provide a superior solution? How?

Re: [Pharo-users] PharoJS

[askoh]

Offray:

Diversity is good. But we can get too much of a good thing.

For example, I see merit in VisualWorks Appex where Smalltalk and JavaScript
are both managed within the System Browser. Additionally, changes to
JavaScript made in the Internet browser are picked up by VisualWorks. Now,
Appex allows live debugging in both front end and back end. And the combined
code is maintained in VisualWorks.

Craig Latta is doing something interesting with SqueakJS which is an
optimized Smalltalk VM in JavaScript and HTML5. It is supposedly able to run
Smalltalk fast inside the browser and access the JavaScript world freely. I
think this route will benefit greatly from WebAssembly.

Can PharoJS borrow some of these ideas? Pros and Cons?

All the best,
Aik-Siong

I appreciate you explanation of Amber and PharoJS. I feel at a lost

where there is a pros and cons comparison of frameworks:

Aida, Teapot, etc?

The sheer number of frameworks just makes it difficult for anyone to commit.
It is terrifying. Can we discuss and consolidate the best features into one

[Pharo-users] Can we auto translate Python to Smalltalk?

[askoh]

Python and JavaScript are driving the movement to Dynamic Languages. In
particular, Python is the language of choice to teach students programming
in universities. So, Smalltalk stands to gain from this shift. We all know
that Smalltalk has the best environment. But we lack the diverse code base.
Can we patch that gap with automatic translation from Python to Smalltalk?
How feasible would it be to auto translate SciPy to SciSmalltalk? Even if it
is imperfect, can we cut the effort by 50% or 80%?

All the best,
Aik-Siong Koh

Re: [Pharo-users] Google building new OS with Dart

Kilon:

Thanks for your input. That is indeed brainstorming. I know the importance
of doing too. But the value of brainstorming is big. A farmer does a lot of
work but is not valued much. Watson and Crick brainstormed a lot and
discovered the double helix. I don't want Smalltalk to miss that power.

Your description of your work and the work of other Smalltalkers shows the
amount of work already done. I too have done CAD and Motion Simulation work
using VisualWorks, C#, SpaceClaim, Inventor. But there is no killer app or
killer use case in all of Smalltalk! How did Python's and Ruby's popularity
leapfrog Smalltalk's? How can we get some attention so that we have
resources to really grow?

China have been widely accused of copying. But I noticed that they have also
picked up discarded technologies that are excellent technologies. Examples
are solar cells, wind turbines, high speed rail, nuclear power, Alpha chip,
MIPS chip, manufacturing, Kylin OS, etc. Perhaps we can make some nation see
Smalltalk for the great technology it has for programming productivity.

Brainstorming is free speech at its best. Please everyone join.

Re: [Pharo-users] Google building new OS with Dart

[askoh]

I think a lot could have change in the two years since I asked how Smalltalk
can benefit from the development of Dart. Originally, Dart was meant to be a
web language. Now it is going to be the main language for an Operating
System. Since it has the full backing of Google, it is in our interest to
ride with it. I wish Smalltalk not to miss out again.

We can of course port the current VM's for Squeak, Pharo, VisualWorks to
Fuchsia, but what do we gain by that? Not much, I think. What if Smalltalk
can do everything Dart can do in Fuchsia - look and feel, apps, scripting,
concurrency, etc. Since Smalltalk seems to be a superset of Dart, can we
auto translate Dart to Smalltalk? Just as Slang converts Smalltalk to C, can
we have a Smalltalk subset that converts to Dart? Can Smalltalk be the
debugger or simulator for Dart development? Can Smalltalk do more than what
Dart can do in Fuchsia?

I wish I have access to the great minds Ben had mentioned. I am hoping that
this thread will draw the best minds and ideas to pave the way for Smalltalk
or its descendants to succeed in the future. Again, let's brainstorm.

All the best,
Aik-Siong Koh

It became news a few days ago. It is called Fuchsia and is meant to run on

Since Dart is pretty close to Smalltalk, how can Smalltalk be the GUI for

Smalltalk to make an impact? Let's brainstorm.
