Some observations, that I'd wish someone else had put online, which could have saved me hours of googling. I hope at some point this page will show up on google and helps someone.

JPGraph error 25070

If you are getting this error and you are certain that all your values are numeric: Please check if your array starts with key 0 (i.e. that array[0] exists and is numeric). The check "to see if all values are numeric" starts at element 0 not 1, and it will fail if there is no element 0. (29/08/2010)

r8168/r8169 Ubuntu 10.04

Say you're using the Realtek r8168 driver instead of the r8169 driver that is supplied with Ubuntu, then you probably know that when you update the kernel, you have to reapply that driver. But if after rebooting your NIC still doesn't work: try turning the power completely off and then on again (actually pull the plug, don't just press the reset button!). Worked for me. Apparently the NIC gets confused by the r8169 driver and has to experience a complete power cycle to return to life. Remember that the board remains powered if you don't actually pull the plug.

IC Capture As lost license key

Last week we lost the license key for our Image Control IC Capture camera software. We emailed their customer support with the serial number of our camera, and they sent you a new key very quickly. So if this happens to you, just email them. (20/08/2010)

Inspiron 6400 Windows 7 x64

If you're installing Windows 7 x64 on a Dell Inspiron 6400 laptop, and you're having problems with the screen (it blanks if you pull out the AC adapter), try this: go into the Intel Graphics Adapter menu and decrease the power savings setting until the laptop screen comes back on. Use an external monitor if you have to. Use Fn-F8 and WIN-P to cycle through the various monitor settings until you find one that works. Haven't yet figured out how to regain control of the adjust brightness feature in Windows 7. Fn-buttons for that also don't work. You can still set the level in the BIOS of course. (19/08/2010)
