  • binary prefix — (unit)   (Or "IEC prefix") A prefix used with a unit of data to mean multiplication by a power of 1024. Binary prefixes are most often used with "byte" (e.g. "kilobyte") but also with bit (e.g. "megabit"). For example, the term kilobyte has historically been used to mean 1024 bytes, and megabyte to mean 1,048,576 bytes. The multipliers 1024 and 1,048,576 are powers of 1024, which is itself a power of two (1024 = 2^10). It is this factor of two that gives the name "binary prefix". This is in contrast to a decimal prefix denoting a power of 1000, which is itself a power of ten (1000 = 10^3). Decimal prefixes are used in science and engineering and are specified in widely adopted SI standards. Note that the actual prefix - kilo or mega - is the same, it is the interpretation that differs. The difference between the two interpretations increases with each multiplication, so while 1000 and 1024 differ by only 2.4%, 1000^6 and 1024^6 differ by 15%. The 1024-based interpretation of prefixes is often still used informally and especially when discussing the storage capacity of random-access memory. This has lead to storage device manufacturers being accused of false marketing for using the decimal interpretation where customers might assume the larger, historical, binary interpretation. In an attempt to clarify the distinction, in 1998 the IEC specified that kilobyte, megabyte, etc. should only be used for powers of 1000 (following SI). They specified new prefixes for powers of 1024 containing "bi" for "binary": kibibyte, mebibyte, etc.; an idea originally propsed by IUPAC. IEC also specified new abbreviations Ki, Mi, etc. for the new prefixes. Many other standards bodies such as NIST, IEEE and BIPM support this proposal but as of 2013 its use is rare in non-technical circles. Specific units of IEC 60027-2 A.2 and ISO/IEC 80000
  • binary pulsar — a pulsar in a binary system.

  • blow an eprom — /bloh *n ee'prom/ (Or "blast", "burn") To program a read-only memory, e.g. for use with an embedded system. This term arose because the programming process for the Programmable Read-Only Memory (PROM) that preceded present-day Erasable Programmable Read-Only Memory (EPROM) involved intentionally blowing tiny electrical fuses on the chip. The usage lives on (it's too vivid and expressive to discard) even though the write process on EPROMs is nondestructive.

  • boycott apple — (legal)   Some time before 1989, Apple Computer, Inc. started a lawsuit against Hewlett-Packard and Microsoft, claiming they had breeched Apple's copyright on the look and feel of the Macintosh user interface. In December 1989, Xerox failed to sue Apple Computer, claiming that the software for Apple's Lisa computer and Macintosh Finder, both copyrighted in 1987, were derived from two Xerox programs: Smalltalk, developed in the mid-1970s and Star, copyrighted in 1981. Apple wanted to stop people from writing any program that worked even vaguely like a Macintosh. If such look and feel lawsuits succeed they could put an end to free software that could substitute for commercial software. In the weeks after the suit was filed, Usenet reverberated with condemnation for Apple. GNU supporters Richard Stallman, John Gilmore and Paul Rubin decided to take action against Apple. Apple's reputation as a force for progress came from having made better computers; but The League for Programming Freedom believed that Apple wanted to make all non-Apple computers worse. They therefore campaigned to discourage people from using Apple products or working for Apple or any other company threatening similar obstructionist tactics (e.g. Lotus and Xerox). Because of this boycott the Free Software Foundation for a long time didn't support Macintosh Unix in their software. In 1995, the LPF and the FSF decided to end the boycott.
  • brachypterous — having very short or incompletely developed wings
  • brachytherapy — a form of radiotherapy in which sealed sources of radioactive material are inserted temporarily into body cavities or directly into tumours
