| NOTE: I am using bash for this. | |
| NOTE2: Another approach for getting tmux would be to use gentoo-prefix or netbsd's pkgsrc. I | |
| didn't have too much luck with gentoo-prefix. NetBSD was pretty straight forward but it had | |
| an old version of tmux (1.1). | |
| Here is how to get tmux compiled if you can get your systadmins to installed it ... or | |
| any other weird reason. I assume you have some basic libraries and headers installed (like | |
| ncurses, etc...). If not, you'll have to compile those ones too. |

Some coding exercises, working up to matching regular expressions with Thompson's algorithm.
I'm assuming you know what a regular expression is and you're a fairly experienced programmer. I don't know if these exercises are either fun or effective -- please comment or fork here or email withal@gmail.com to help me improve them.
So you managed to break Julia. Congratulations! Collected here are some general procedures you can undergo for common symptoms encountered when something goes awry. Including the information from these debugging steps can greatly help the maintainers when tracking down a segfault or trying to figure out why your script is running slower than expected.
If you've been directed to this page, find the symptom that best matches what you're experiencing and follow the instructions to generate the debugging information requested. Table of symptoms:
