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
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.
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.
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 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.

Again is the fifth extended play by South Korean girl group T-ara, released on October 10, 2013 by Core Contents Media. It was the first album released after member Lee Areum left the group, and the first to feature the original six-member line-up since T-ara's debut.
On October 6, 2013, T-ara announced the impending release of double lead singles to promote their upcoming EP, Again. The album was released digitally on October 10, including the singles "Number 9" (넘버나인) and "Because I Know" (느낌 아니까; Neukkim Anikka) and their music videos. "Number 9" is an electro-pop dance song with sad lyrics and melody. It was choreographed by Yama & Hotchicks, who also choreographed "Bo Peep Bo Peep". "Because I Know" is a mid-tempo song with an acoustic feel.
A repackaged edition of the EP, Again 1977, was released on December 4, 2013. It contains two new songs, "Again 1977" and "Do You Know Me", a remake of Sand Pebbles' 1977 hit, "What Should I Do". The EP was repackaged and digitally re-released again, on December 14, 2013, as White Winter with two Christmas songs, "Hide and Seek" and "Middle of Winter Hide and Seek".
Again (foaled 22 May 2006) was an Irish Thoroughbred racehorse and broodmare. She was one of the leading Irish two-year-old fillies of 2008, when she won three of her five races including the Debutante Stakes and the Moyglare Stud Stakes. She recorded her most important win when taking the Irish 1,000 Guineas on her three-year-old debut, but was beaten in her three subsequent races.
Again is a bay mare with a white blaze bred in Ireland by Southern Bloodstock, a breeding operation associated with the Coolmore Stud. She was sired by Danehill Dancer, the Leading sire in Great Britain & Ireland in 2009, whose other progeny have included Mastercraftsman and Choisir. Again's dam Cumbres, was an unraced half-sister of the multiple Group One winner Montjeu. During her racing career, the detail of Again's ownership changed from race to race: she was alternately described as being owned by Michael Tabor and by a partnership of Tabor and Susan Magnier. She was trained by David Wachman, the son-in-law of Coolmore's head John Magnier, at Goolds Cross in County Tipperary.
