• How to avoid escaping by accident in PERL using system()?

  - by Brian

  I want to run some commands using the system() command, I do this way: execute_command_error("trash-put '/home/$filename'"); Where execute_command_error will report if there was an error with whatever system command it ran. I know I could just unlink the file using Perl commands, but I want to delete stuff using trash-put as it's a type of recycling program. My problem is that $filename will sometimes have apostrophes, quotes, and other weird characters in it that mess up the system command or Perl itself.

• How to learn open source library API without good documentation

  - by Turtle

  I am recently working on the open source library openmetaverse which is designed as an open source substitution of second life viewer. I think the problem is that it is not well documented. Sometimes, I just misunderstand the API when I really used it in real program which is very annoying because sometimes you need to write many code. But how to make sure the API just acts the way you expected? So what is your way to learn new API without good documentation?

• I've heard that LaTeX is Turing complete. Are there any programs written in LaTeX?

  - by ire_and_curses

  It's possible to do interesting things with what would ordinarily be thought of as typesetting languages. For example, you can construct the Mandelbrot set using postscript. It is suggested in this MathOverflow question that LaTeX may be Turing-complete. This implies the ability to write arbitrary programs (although it may not be easy!). Does anyone know of any concrete example of such a program in LaTeX, which does something highly unusual with the language?

• Geometry library for python (or C++) for CAD-like operations?

  - by gct

  I'm trying to put together a simple program that will let me visualize a series of consecutive cuts on a wood panel using a router with a particular cutting head. I'm trying to find a decent geometry library that will give me a shortcut through the CAD-like stuff. Specifically, I'd like to be able to define a rectangular solid (the wood panel) and then define a bit profile shape, and take cuts through the rectangular solid (sometimes on a straight line, sometimes on a circular arc). Does anyone know of anything that will do this?

• Does a programmer "document template" with tags exist for Windows?

  - by Anthony Forloney

  I was wondering (if possible) if there was a program/tool/utility that when I create a new file and provide it with an extension that it creates the tags automatically? For example, a new file I create called index.php would have the appropriate tags auto-generated inside: <?php ?> I hope you get the idea. Any information regarding this would be helpful.

• Anchor Window to Screen Edges in WPF

  - by Kirk

  I've decided to teach myself C# by writing a music player in Visual Studio 2010. I went with WPF because from what I hear it sounds like it will be a good base to skin from. I want to program my window with the behavior where if the window comes to the edge of a screen (within 10px or so) it will snap to the screen edge. What's the best way to go about this?

• Go - Raise an exception

  - by nevalu

  I would want to raise an exception as it's made in Python or Java --to finish the program with an error message--. An error message could be returned to a parent function: func readFile(filename string) (content string, err os.Error) { content, err := ioutil.ReadFile(filename) if err != nil { return "", os.ErrorString("read " + filename + ": " + err) } return string(content), nil } but I want that it can be finished when the error is found. Would be correct the next one? func readFile(filename string) (content string) { content, err := ioutil.ReadFile(filename) defer func() { if err != nil { panic(err) } }() return string(content) }

• Detect/Redirect core dumps (when a software crashes) on Windows

  - by ereOn

  Hi, For my work, I need to create a service that will detect an abnormal program termination and, instead of displaying a message to the user (default behavior), send the generated core dump to a remote server. I'm pretty sure this can be done, but I have absolutely no clue on where to start. Is there any API/registry settings for this ? Thank you.
