Hi, it has been a while now since the last changes to the Voltronic Sunny code, because it's working just fine. I saw that there are a lot of changes in the master tree and my question is what I should do with the Voltronic Sunny part? Does it still make sense to try to make a pull-request out of it? Best, Nick

I seem to be able to lock my machine by going into wpa_cli and asking it to 'reassoc'. The reason for question mark after "hard" is that debug information (caused by wlandebug and athdebug) is being printed on the console. The only way to get machine's attention is to hold power button for 8 seconds. Note: manual reassociation is just the handy way to reproduce the problem

Hello, Eversince I upgraded Samba to 2.0 version I've gotten so many calls from the users regarding Excel 'save as HTML' problem. What seems to be happening is that the users cannot save their Excel spreadsheet as html file when they were able to with the previous Samba version we had installed (Samba 1.9.18p10).

Hey everyone, I just wanted to drop onto the list and say hi. My name is Chad Humphries and I am a partner at a ruby and rails shop in Columbus, OH called EdgeCase. Up until two months ago we were doing all of our dev work in test:unit. I had read about RSpec before and after hearing Jim Weirich speak at the Columbus Ruby Brigade about similar ideas I decided to give it a go for a

I thought I would write a lottery number generator since I have not had any luck winning the big jackpot - http://megamillions.com/. So far, after over 1.2 million tries, I still have not hit all the numbers from yesterday: 2, 17, 22, 32, 51, 35 (last one is the mega ball). Fun little project that and I thought others would be interested. Let me know if you have a cleaner implementation in mind.
