Mac stamina indicator, please help
Hi everyone,
for a CPU intensive piece of software I’m writing I’m contemplating to integrate an integer value representing the computer’s speed into the code to receive the best fidelity/performance ratio. To see if this returns useful results on your Macs, could you please run this code locally on your computer and post results back here?
Thank you

Interesting concept!
But why Mac-only?

@hrant
This particular code relies on the sysctl command and should work on more UNIXes, I guess. I’m working on a plugin for Glyphs and RoboFont, so Windows is not of interest at the moment.
The last number in the output would be the maximum amount of items the plugin draws into the glyph view before rendering slows down. The more, the better the illustration, the slower. But I don’t want to compromise on snappiness.

I get an err message from Terminal running the code.

Nina wins!
@dezcom:
That's exactly why I was posting this. Could you please share the error message?

Hi Yanone. This is what I got.

Interesting :)
You need to save the file somewhere and then run it in the Terminal thusly: "python stamina.py" given you’re already in the correct directory. If not, "cd" first.

Thank you everyone. I think these are more or less useful results.

@Paul: Holy shit! You win.
@Bert Vanderveen: Permission denied on what? Executing stamina.py (either change permissions with "chmod 755 stamina.py" or simply use "python stamina.py") or with executing the sysctl call inside the Python code? The latter would be not so good for me.

I protest, Mr. Pvanderlaan submitted after the deadline! :)

Paul, exactly what kind of type design are you doing? ;-)

@dezcom – Yuck! Obviously, bash is acting as if stamina.py was a shell script instead of passing the script to the Python interpreter as it should. Workaround: 'python stamina.py'.
Aside: Tried running stamina.py on a Linux box, but since it does not have the sysctl program, the result was predictably limited.

Chris, it looks like you're trying to run it directly in the terminal, maybe by pasting code? Try doing this instead:
1. At the terminal prompt, type "python " including the space, but not the quotes, and don't hit return yet.
2. Drag the "stamina.py" file onto the terminal window. (This enters the path to the script.)
3. Now hit return. (Be sure Terminal is the front-most app when you do this.)

BTW, you can run scripts like this directly from text editors such as Textmate and BBEdit. The results are displayed in a new window.

I actually ran it from within FontLab!
