Hey Y'all,
Check this out. Maybe they could use an open source rotary power plant
in their LSA. I bet they would be happy to host the ECU code.

Oh, one more thing. I read in the article (Not to let the cat out of
the bag, but I am hopefully looking to release some specialized 3D
modeling software as open source next year.)
Maybe we will have a Linux 3D CAD application appropriate to aircraft
design.

I hope it has a better user interface than Solidworks.
I am taking a course in Solidworks and it has an obsolete
modal GUI. Modal GUI's went out with Word Perfect 30 years
ago :) My SW instructor did not know what the word meant.
http://en.wikipedia.org/wiki/Mode_%28computer_interface%29
"In user interface design, a mode is a distinct setting within a computer
program or any physical machine interface, in which the same user input
will
produce perceived different results than it would in other settings. The
best-known modal interface components are probably the Caps lock and Insert
keys on the standard computer keyboard, both of which put the user's typing
into a different mode after being pressed, then return it to the regular
mode after being re-pressed."
A precise definition is given by Jef Raskin in his book "The Humane
Interface":
"An human-machine interface is modal with respect to a given gesture when
(1) the current state of the interface is not the user's locus of attention
and (2) the interface will execute one among several different responses to
the gesture, depending on the system's current state."
"In Raskin's sense and according to his definition, an interface is not
modal
as long as the user is fully aware of its current state. Raskin refers to
this as 'locus of attention' (from the Latin word locus meaning "place" or
"location"). Typically a user is aware of a system state if the state
change
was purposefully initiated by the user, or if the system gives some strong
signals to notify the user of the state change. If the user's locus of
attention changes to a different area, the state of the interface may then
represent a mode since the user is no longer aware of it."

My preferred Unix style text editor is VI. I don't have a problem with
modal interfaces.
You are right about Solidworks. It's almost as bad as CATIA.

Hey, I just found:
http://en.wikibooks.org/wiki/OpenSCAD_User_Manual
Says it can produce STL and OFF file formats. Are they anything that we
can use to make files for the CNC guys?
Mark LaPierre
Does it work on CentOS?
Paul Lamar
There are no CentOS RPM files that I know of, but I'm looking into it.
If I can't find an RPM file I'll try building it from source code.
Sometimes that works. Most times not so much.
Mark LaPierre
How about Mint? I am running both these days.
