I have not. I'll try that next. |

Story, as I read it, goes that it was developed by Realtek, who didn't |
| 35 |
think to open-source it. Larry Finger asked Realtek for the driver, they |
| 36 |
provided it, as well as permission to get it distributed further. |

It's not possible to have less free time than I had in the past few |
| 71 |
months. Even having this kid on my lap while I write this is a luxury of |
| 72 |
free time I haven't had in ages. Nearly every non-work, non-sleep moment |
| 73 |
was dedicated to preparing for this guy just showing up. Looking forward |
| 74 |
to when he's big enough for the mai-tai; that'll afford me even more |
| 75 |
flexibility. |

Though I'll probably wind up eating my own words... |

Combined with my job getting busier and busier, yes. I'm flattered I was |
| 83 |
missed. :) |
