Seek animal foods as your primary source of choline, but augment with plant based sources as desired. Cruciferous Veggies Veggies from this group, including cauliflower, cabbage, bok choy and broccoli, boast around 65 mg of choline per cup cooked.
Since its normally easier to conduct measurements of voltage rather than power, some prefer using the voltage of a system as a reference. As a result, the dBu unit of measure is used many times in audio systems vice dBm. The dBu unit is calculated by: A = 20log(V2/V1).In this formula, the reference level is 0.77 volts rms. In most audio equipment, the normal dBu line level is 4 dBu.ince its normally easier to conduct measurements of voltage rather than power, some prefer using the voltage of a system as a reference.

What is a (raid-controller-) BBU for? I am wondering what's the purpose of a BBU. My first understanding was, that it enables the cache to write the data to the disc during a power failure. But some specifications say that a BBU can hold its data for up to 72h. I'd expect the data to be written to the disc within milliseconds (given, that the disc still has power, too).
