Trimming (computer programming)

In computer programming, trimming (trim) or stripping (strip) is a string manipulation in which leading and trailing whitespace is removed from a string.

For example, the string (enclosed by apostrophes)

would be changed, after trimming, to

Definition of whitespace

The characters which are considered whitespace varies between programming languages and implementations. For example, C traditionally only counts space, tab, line feed, and carriage return characters, while languages which support Unicode typically include all Unicode space characters. Some implementations also include ASCII control codes (non-printing characters) along with whitespace characters.

Java's trim method considers ASCII spaces and control codes as whitespace, contrasting with the Java isWhitespace() method, which recognizes all Unicode space characters.

Delphi's Trim function considers characters U+0000 (NULL) through U+0020 (SPACE) to be whitespace.

Usage

Following are examples of trimming a string using several programming languages. All of the implementations shown return a new string and do not alter the original variable.

Trim (computing)

A Trim command (known as TRIM in the ATA command set, and UNMAP in the SCSI command set) allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally.

Trim was introduced soon after SSDs were introduced. Because low-level operation of SSDs differs significantly from hard drives, the typical way in which operating systems handle operations like deletes and formats resulted in unanticipated progressive performance degradation of write operations on SSDs. Trimming enables the SSD to handle garbage collection overhead, which would otherwise significantly slow down future write operations to the involved blocks, in advance.

Although tools to "reset" some drives to a fresh state were already available before the introduction of trimming, they also delete all data on the drive, which makes them impractical to use for ongoing optimization. By 2014 many SSDs had internal idle/background garbage collection mechanisms that work independently of trimming; although this successfully maintains their performance even under operating systems that do not support Trim, it has the associated drawbacks of increased write amplification and wear of the flash cells.

Trim (sewing)

Trim or trimming in clothing and home decorating is applied ornament, such as gimp, passementerie, ribbon, ruffles, or, as a verb, to apply such ornament.

Before the industrial revolution, all trim was made and applied by hand, thus making heavily trimmed furnishings and garments expensive and high-status. Machine-woven trims and sewing machines put these dense trimmings within the reach of even modest dressmakers and home sewers, and an abundance of trimming is a characteristic of mid-Victorian fashion. As a predictable reaction, high fashion came to emphasize exquisiteness of cut and construction over denseness of trimming, and applied trim became a signifier of mass-produced clothing by the 1930s. The iconic braid and gold button trim of the Chanel suit are a notable survival of trim in high fashion.

In home decorating, the 1980s and 1990s saw a fashion for dense, elaborately layered trimmings on upholstered furniture and drapery.

Today, most trimmings are commercially manufactured. Scalamandré is known for elaborate trim for home furnishings, and Wrights is a leading manufacturer of trim for home sewing and crafts. Trims are used generally to enhance the beauty of the garments. It attracts buyers. Appropriate use of it creates more value of the product.

Dan.

Dan. may mean:

Dan (newspaper)

Dan (Serbian Cyrillic: Дан, pronounced [dâːn]; English: The Day) is a daily newspaper published in Montenegro. It took its name from the old day Cetinje monthly newspaper that was published in the old Montenegrin state at the beginning of the 20th century. As of 2009 it held the second place after Vijesti with a share of an estimated 31,6% of the country's total readers.

History and profile

The first issue of Dan appeared on 31 December 1999. Right from its start, Dan was one of the harshest critics of Milo Đukanović's regime in Montenegro. In May 2001, as Croatian magazine Nacional) began a series of articles and insider interviews on state-sponsored cigarette smuggling in Montenegro under Djukanovic's regime, Dan was the only media outlet in the country to bring the details of the 'Nacional affair' to the Montenegrin public.

On 27 May 2004 Dan founder and editor-in-chief Duško Jovanović was assassinated on a Podgorica street in front of the paper's offices. Even though a prolonged police investigation produced a couple of arrests, along with an immediate assassin-suspect currently on trial, the individuals behind the murder have still not been identified. It is alleged that the DPS-controlled government both sponsored and covered up the event.

Nandor (Middle-earth)

In the fictional world of J. R. R. Tolkien, the Nandor (singular Nando) were Elves of the Teleri, the third clan of Elves.

Internal History of the Nandor

When the marching Elves reached the Hithaeglir (Misty Mountains) some left the Great Journey under their leader Lenwë (Dan or Denweg in Nandorin). These Elves turned south along the Great River (Anduin). Nandor means in Quenya "those who turned back".

Many years later a group of Nandor under Denethor, son of Lenwë, crossed the Ered Luin into Ossiriand, which was after named Lindon, or Land of the singers, after these elves. They became known as the Laiquendi (singular Laiquendë) or Green Elves.

The Silvan Elves of Mirkwood and Lothlórien were Nandor (but most of their lords were not), as were the Elves which dwelt at Edhellond near Dol Amroth. They also mixed with Avarin Elves and in minor part with the Sindar and the Noldor (the latter especially mixing with the Silvan Elves of Lothlórien, these were exiles and survivors from the Elven realm of Eregion).
