Co-founder of Harroun Motor Co. in Fort Wayne, Michigan. Race Car Driver - Winner of the first Indianapolis 500 in 1911. His average speed was 74.59 mph (120.4kph), driving a Marmon.=20 He was the first to publicly use an automotive rear-view mirror=20 and so was rumored to be the inventor of the idea. However=20 Harroun readily acknowledged that he'd first spotted the rear-view=20 mirror years earlier on horse-drawn taxis in Chicago.
Interview with Dick Harroun, son of Ray:
Even over the phone, you can hear the pride in Dick Harroun's voice as = he talks about his father's victory in the first Indy 500.=20 "He won the year before -- in 1910 -- but it didn't mean much = because the track hadn't been paved with bricks yet. They ran on dirt.=20 "In those days, each car had two men in the cockpit -- a driver and = a mechanic. The mechanic's main job was to look back and see who was = coming up on them. My father wanted to go it alone, and they banned him = from the race when he showed up on race day without a mechanic.=20 "It was 15 minutes before the start, and he went back into his = garage and mounted a rearview mirror just over the dashboard."=20 It was a wide rectangular box with a mirror inside it. The officials = saw what he had done and let him run.=20 "What really won the race for him, though, was that he went to the = Firestone tire company and asked them how fast he could run without = blowing any tires," Dick Harroun said. "He had noticed that the other = cars were going into the pits all the time to have their tires changed. = Firestone told him if he kept it under 75 mph, he'd be OK.=20 "He had to change only a couple of tires and a couple of them lasted = all the way."=20 So, Ray Harroun created history in his Marmon Wasp by lasting more = than six hours on the bumpy track and finishing nearly a lap ahead of = his nearest competitor.=20 Ray Harroun never raced at Indy again but managed several teams. He = hung around racing for the rest of his life, passing away in 1968.=20 "Obviously, I wasn't there when he won, but he spoke about it many = times," Dick Harroun said. "He got credit for the rearview mirror, but = what many people don't know is that he also was the man who developed = bumpers on our cars."=20 He started laughing over the phone.=20 "That business of the mirror was something of a joke," he said. "My = father said the mirror jiggled so much during the race that he could = never use it. But I guess they thought it looked good, so they let him = race."=20
So, even though this is a rediculously inappropriate question for = info-performer, there are still valuable lessons to learn from it: 1. Invention is often an incremental process (horse-drawn taxi mirror = -> automobile mirror) 2. The leading edge/first instance/latest thing can be more about = portent than utility (uselss jiggly mirror)
Michael "The early bird" Jones
P.S. The oldest US patent I found was #1365247, to Kennedy issued in Jan = 1921. Don't know about the 10 year interval batween Harroun and Kennedy.

Hi, I'm using Performer on Linux and for the pefly program I'm trying to use my own GUI. For that I wrote GUI in LessTif and in main.C I've forked this GUI as a seperate process. The callback functions added to the buttons in the GUI, were able to access the shared variables, say ViewState->gui, for example.
Now the problem is, the callback functions were not able to update the shared variables. what might be the problem. ?. How do i make the callback back functions modify the shared variables. ?? Please help

If you're using SharedArenas with 2.3 or 2.3.1, then that's the problem. Performer 2.3 and 2.3.1 are single-process only and do not implement SharedArenas. If you're GUI must run in a separate process, then you'll have to create a shared memory area yourself with shmget(), shmat(), etc.

Has anyone tried compiling this on Linux? The source in: /usr/share/Performer/src/lib/libpfdb/libpfiv/ compiles rather painlessly, but when I try to load a *.iv file, I get:
.... PF Warning: pfdFindConverterDSO() - Could not load DSO for extension "iv20" PF Warning: pfdFindConverterDSO() - Could not load DSO for extension "iv" PF Warning: pfdLoadFile() - Unable to load file /home/shankar/subdivision/newEq3.iv because of problem finding pfdLoadFile_iv
This looks like fix-able, but if someone has already figured it out, I would rather find my Friday evening doing something else :-(
Thanks.
Sincerely,
shankar

The following assumes you're compiling on Linux.....
I have a libpfiv.so pre-compiled with the open-source OpenInventor here:
If you're using TGS's Inventor, then try setting PFLD_LIBRARY_PATH to where your libpfiv.so is and set PFNFYLEVEL to 7....I suspect a symbol of some kind is unresolved and dlopen() is failing. Turning on those two environment variables will help identify which symbol is unresolved.

I've got some trouble to load '.iv' files. I'm running the latest version of Performer on a Linux Slackware 7, GeForce, XFree4.0.1.
I downloaded the 'libpfiv.so' and the OpenInventor libraries found on reality.sgi.com/flynnt, and since then I am able to load '.iv' file with the precompilated version of 'perfly'. Then I compiled 'perfly' by making 'make' in the '/usr/share/Performer/src/sample/C', and I am not able to load any '.iv' file with this version... I get the :
PF Warning: pfdFindConverterDSO() - Could not load DSO for extension "iv20" PF Warning: pfdFindConverterDSO() - Could not load DSO for extension "iv" PF Warning: pfdLoadFile() - Unable to load file ....iv because of problem finding pfdLoadFile_iv
Is there something to do with dlopen / dlsym ?
Any answer, help or advice will be greatly appreciated. Thanks for reading this message.

From: Tom Flynn <flynnt++at++cthulhu.engr.sgi.com> Date: Sat, 9 Sep 2000 16:43:29 -0700 Subject: Re: trouble loading .iv files
Interesting...
After turning on PFLD_LIBRARY_PATH=3D/usr/lib/libpfdb and setting PFNFYLEVE= L to 7, it said that dlopen() was failing because __XmStrings was unresolved.
Try adding NEED_MOTIF_LIBS=3D1 at the top of the perfly makefile and try again. In the Performer tree, we just happen to link with -lXm...we really don't need to since perfly doesn't use Motif...that really shouldn't be there.
Inventor (libInventorXt anyway) uses Motif. In the libSoXt Makefile we're not linking with -lXt -lXm when we create the library, so the run-time linker didn't know to pickup those libraries when it loaded libInventorXt when perfly loaded the libpfiv.so loader.
I'll check the fix into Inventor later today. Thanks, tom
