- objective modula-2 — (language) (Or "ObjM2") An extension to Modula-2 for Cocoa and GNUstep software development. Objective Modula-2 follows the Objective-C object model and retains the bracketed Smalltalk message passing syntax used in Objective-C. Classes written in ObjM2 can be used within ObjC and vice versa. ObjM2 also retains Modula-2's data encapsulation features, namely nested modules with explicit import and export lists. Due to the strict type checking in Modula-2, ObjM2 can be considered a much safer programming language than is ObjC, yet losing none of the capabilities of ObjC.

- run length limited — (storage) (RLL) The most popular scheme for encoding data on magnetic disks. RLL packs up to 50% more data on a disk than MFM. Groups of bits are mapped to specific patterns of flux. The density of flux transitions is limited by the spatial resolution of the disk and frequency response of the head and electronics. However, transitions must be close enough to allow reliable clock recovery. RLL implementations vary according to the minimum and maximum allowed numbers of transition cells between transitions. For example, the most common variant today, RLL 1,7, can have a transition in every other cell and must have at least one transition every seven cells. The exact mapping from bits to transitions is essentially arbitrary. Other schemes include GCR, FM, Modified Frequency Modulation (MFM). See also: PRML.
