I suppose there's some sort of circuit I can do that will prevent short pulses like that?
I usually use a 10uF capacitor between RESET and GND, but there are other methods too.
That's all I have to do? Put a 10 microfarad between reset and ground and it won't flash the LEDs anymore?
The capacitor absorbs the reset pulse enough to not reset the Arduino. However, you won't then be able to program the board without pressing the reset button at just the right moment. So, make the capacitor removable
I'll just put one end of the cap to my ground line on the breadboard and the other to reset...

Actually, scratch that... apparently the UNO doesn't reset when opening serial. Not sure why it was blinking before, but it stopped now..
The UNO resets when the computer activates the DTR line of the serial connection. It is possible for the computer to open the serial connection without setting that DTR line, so it may not reboot. Not all operating systems can do that properly though - I know Linux can only turn off setting of the DTR line on a port once the port has been opened.
