SLUB (software)

SLUB ("the unqueued slab allocator") is a memory management mechanism intended for the efficient memory allocation of kernel objects which displays the desirable property of eliminating fragmentation caused by allocations and deallocations. The technique is used to retain allocated memory that contains a data object of a certain type for reuse upon subsequent allocations of objects of the same type. It is used in Linux and became the default allocator since 2.6.23.

The Marriage (Gombrowicz play)

The Marriage (Polish: Ślub) is a play by the Polish writer Witold Gombrowicz, written in Argentina after World War II. The narrative takes place in a dream, where the dreamer transforms into a king and plans to marry his fiancée in a royal wedding, only as a means to save their integrity. A Spanish translation was first published in 1948, followed by the original Polish version in 1953. The play was first performed in 1960.

Plot

Henryk has a dream where his childhood home has been turned into an inn. His father is the innkeeper and his fiancée, Mania, is a serving maid. Drunkards begin to cause trouble and pursue the father. The father, to defend his dignity, claims that he is untouchable, "like a king". This would make Henryk a prince. Henryk is then promised a marriage with Mania, a marriage worthy of a royal in order to restore her purity.

As the marriage is prepared—it will be celebrated by none other than a bishop—Henryk begins to have doubts about the validity of the dream. The drunkard enters and is about to fight Henryk when the scene changes into a court banquet. The drunkard is now an ambassador of a hostile nation. The drunkard makes Henryk's friend Władzio hold a flower over Mania's head. He then makes the flower disappear, leaving the two in an improper position, to Henryk's indignation.

Novelty yarns

Novelty yarns include a wide variety of yarns made with unusual features, structure or fiber composition such as slubs, inclusions, metallic or synthetic fibers, laddering and varying thickness introduced during production. Some linens, wools to be woven into tweed, and the uneven filaments of some types of silk are allowed to retain their normal irregularities, producing the characteristic uneven surface of the finished fabric. Man-made fibres, which can be modified during production, are especially adaptable for special effects such as crimping and texturizing.

Complex yarns

Novelty yarns are sometimes referred to as complex yarns. A yarn which makes a fabric is not always smooth and uniform. Complex yarns are the uneven yarns which may be thick and thin or have curls, loops, twists and even differently coloured areas along their length. This look of the yarns are used to add interesting effects in fabrics. In complex ply two or more complex yarns are twisted around each other to form loops, curls and knots to create fancy effects. Many knitting yarns are complex ply yarns which give interesting textures in finished products.

Software

Computer software also called a program or simply software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of computer programs, libraries and related non-executable data (such as online documentation or digital media). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other.

At the lowest level, executable code consists of machine language instructions specific to an individual processor—typically a central processing unit (CPU). A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also (indirectly) cause something to appear on a display of the computer system—a state change which should be visible to the user. The processor carries out the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction, or interrupted.

Software (novel)

Software is a 1982 cyberpunk science fiction novel written by Rudy Rucker. It won the first Philip K. Dick Award in 1983. The novel is the first book in Rucker's Ware Tetralogy, and was followed by a sequel, Wetware, in 1988.

Plot summary

Software introduces Cobb Anderson as a retired computer scientist who was once tried for treason for figuring out how to give robots artificial intelligence and free will, creating the race of boppers. By 2020, they have created a complex society on the Moon, where the boppers developed because they depend on super-cooled superconducting circuits. In that year, Anderson is a pheezer — a freaky geezer, Rucker's depiction of elderly Baby Boomers — living in poverty in Florida and terrified because he lacks the money to buy a new artificial heart to replace his failing, secondhand one.

As the story begins, Anderson is approached by a robot duplicate of himself who invites him to the Moon to be given immortality. Meanwhile, the series' other main character, Sta-Hi Mooney the 1st — born Stanley Hilary Mooney Jr. — a 25-year-old cab driver and "brainsurfer", is kidnapped by a gang of serial killers known as the Little Kidders who almost eat his brain. When Anderson and Mooney travel to the Moon together at the boppers' expense, they find that these events are closely related: the "immortality" given to Anderson turns out to be having his mind transferred into software via the same brain-destroying technique used by the Little Kidders.
