Full stack developer: A muchâlauded position, and rightfully so, the full stack developer is one who is adept at all aspects of the development process and is capable of contributing code and functional solutions every step of the way, from planning and design to both front- and back-end coding.
1 also called delta rhythm, the slowest of several types of brain waves, characterized by a frequency of 4 Hz and a relatively high voltage. Delta waves are deep-sleep waves associated with a dreamless state from which an individual is not easily aroused. Compare alpha wave, beta wave, theta wave. 2 (in cardiology) a slurring of the QRS portion of an electrocardiogram tracing caused by preexcitation in Wolff-Parkinson-White syndrome. Cardiology An EKG finding in WPW syndrome, seen as a slow upstroke of the QRS wave in a background of short P-R intervals See Wolff-Parkinson-White syndrome.
Delta waves, like all brain waves, can be detected by electroencephalography (EEG). Delta waves were originally defined as having a frequency between 1-4 Hz Delta waves begin to appear in stage 3 sleep, but by stage 4 nearly all spectral activity is dominated by delta waves.
