  • file descriptor leak — (programming)   (Or "fd leak" /F D leek/) A kind of programming bug analogous to a core leak, in which a program fails to close file descriptors ("fd"s) after file operations are completed, and thus eventually runs out of them. See leak.
  • flame-fusion process — Verneuil process.
  • general public virus — (software, legal)   A pejorative name for some versions of the GNU project copyleft or General Public License (GPL), which requires that any tools or application programs incorporating copylefted code must be source-distributed on the same terms as GNU code. Thus it is alleged that the copyleft "infects" software generated with GNU tools, which may in turn infect other software that reuses any of its code.

  • hipparchus satellite — an astronometric satellite launched in 1989 by the European Space Agency that measured the position, proper motion, and brightness of 118 218 stars down to 12th magnitude and the magnitude and colour of a million stars down to 10th magnitude
  • hire-purchase system — a system of payment for a commodity in regular installments while using it.
  • household appliances — devices or machines, usually electrical, that are in your home and which you use to do jobs such as cleaning or cooking
  • hydraulic suspension — a system of motor-vehicle suspension using hydraulic members, often with hydraulic compensation between front and rear systems (hydroelastic suspension)

  • hyperadrenocorticism — Cushing's syndrome.
  • hypercholesterolemia — the presence of an excessive amount of cholesterol in the blood.
  • hypercholesterolemic — (pathology) Of, pertaining to, or having hypercholesterolemia.
  • hyperhomocysteinemia — (medicine) The presence of an excessive amount of homocysteine in the blood.
  • implicit parallelism — (parallel)   A feature of a programming language for a parallel processing system which decides automatically which parts to run in parallel. The best way of providing implicit parallelism is still (1995) an active research topic. The problem is to generate the right number of parallel tasks of the right size (or "granularity"). Too many tasks and the system gets bogged down in house-keeping, or memory for waiting tasks runs out, too few tasks and processors are left idle. The best performance is usually achieved with explicit parallelism where the programmer can annotate his program to indicate which parts should be executed as independent parallel tasks.
  • income tax inspector — a person whose job is to assess individuals' income tax liability
  • incomprehensibleness — The state of being incomprehensible.
  • indicated horsepower — the horsepower of a reciprocating engine as shown by an indicator record. Abbreviation: ihp, IHP.
  • infectious hepatitis — hepatitis A.
  • insolvency provision — the right of employees of a firm that goes bankrupt or into receivership to receive money owed to them as wages, etc
  • instruction prefetch — (architecture)   A technique which attempts to minimise the time a processor spends waiting for instructions to be fetched from memory. Instructions following the one currently being executed are loaded into a prefetch queue when the processor's external bus is otherwise idle. If the processor executes a branch instruction or receives an interrupt then the queue must be flushed and reloaded from the new address. Instruction prefetch is often combined with pipelining in an attempt to keep the pipeline busy. By 1995 most processors used prefetching, e.g. Motorola 680x0, Intel 80x86.
  • insulin-coma therapy — a former treatment for mental illness, especially schizophrenia, employing insulin-induced hypoglycemia as a method for producing convulsive seizures.
  • interplanetary space — the region of space occurring around the sun and planets of the solar system. The density is normally negligible although cosmic rays, meteorites, gas clouds, etc, can occur
  • isometric projection — a type of axonometric projection in which the object is shown with its three principal axes all equally tilted from the plane of viewing, with two of them usually tilted 30 degrees upward from the horizontal
  • judicial proceedings — any action involving or carried out by a court of law
  • justice of the peace — a local public officer, usually having jurisdiction to try and determine minor civil and criminal cases and to hold preliminary examinations of persons accused of more serious crimes, and having authority to administer oaths, solemnize marriages, etc.
  • keep a straight face — look serious, avoid smiling
  • king charles spaniel — a variety of the English toy spaniel having a black-and-tan coat.
  • life-support machine — A life-support machine is the equipment that is used to keep a person alive when they are very ill and cannot breathe without help.
  • light-weight process — (operating system, parallel)   (LWP) A single-threaded sub-process which, unlike a thread, has its own process identifier and may also differ in its inheritance and controlling features. Several operating systems, e.g. SunOS 5.x, provide system calls for creating and controlling LWPs.
  • lighthouse coffeepot — a coffeepot of the late 17th and 18th centuries, having a tapering, circular body with a domed lid.
  • linear address space — A memory addressing scheme used in processors where the whole memory can be accessed using a single address that fits in a single register or instruction. This contrasts with a segmented memory architecture, such as that used on the Intel 8086, where an address is given by an offset from a base address held in one of the "segment registers". Linear addressing greatly simplifies programming at the assembly language level but requires more instruction word bits to be allocated for an address.
  • linguistic geography — dialect geography.
  • lost property office — room for mislaid objects
  • lunisolar precession — the principal component of the precession of the equinoxes, produced by the gravitational attraction of the sun and the moon on the equatorial bulge of the earth.
  • magneto-optical disk — (hardware, storage)   (MO) A plastic or glass disk coated with a compound (often TbFeCo) with special optical, magnetic and thermal properties. The disk is read by bouncing a low-intensity laser off the disk. Originally the laser was infrared, but frequencies up to blue may be possible giving higher storage density. The polarisation of the reflected light depends on the polarity of the stored magnetic field. To write, a higher intensity laser heats the coating up to its Curie point, allowing its magnetisation to be altered in a way that is retained when it has cooled. Although optical, they appear as hard drives to the operating system and do not require a special filesystem (they can be formatted as FAT, HPFS, NTFS, etc.). The initial 5.25" MO drives, introduced at the end of the 1980s, were the size of a full-height 5.25" hard drive (like in IBM PC XT) and the disks looked like a CD-ROM enclosed in an old-style cartridge In 2006, a 3.5" drive has the size of 1.44 megabyte diskette drive with disks about the size of a regular 1.44MB floppy disc but twice the thickness.
  • malpighian corpuscle — Also called kidney corpuscle, Malpighian body. the structure at the beginning of a vertebrate nephron, consisting of a glomerulus and its surrounding Bowman's capsule.
  • matched-pairs design — (of an experiment) concerned with measuring the values of the dependent variables for pairs of subjects that have been matched to eliminate individual differences and that are respectively subjected to the control and the experimental condition
  • megakaryocytopoiesis — (biology) The cellular development process that leads to platelet production.
  • meissner's corpuscle — tactile corpuscle.
  • mickey mouse program — (jargon)   The North American equivalent of a "noddy program", i.e. trivial. The term doesn't necessarily have the belittling connotations of mainstream slang "Oh, that's just mickey mouse stuff!"; sometimes trivial programs can be very useful.
