Some common reasons to use templates are to implement generic programming ( avoiding sections of code which are similar except for some minor variations ) or to perform automatic compile-time optimization such as doing something once at compile time rather than every time the program is run — for instance, by having the compiler unroll loops to eliminate jumps and loop count decrements whenever the program is executed.

Some guitarists used Jimi Hendrix-influenced distortion and wah-wah effects to get a sustained, heavy tone, or even used rapid-fire guitar shredding techniques, such as tapping and tremolo bar bending.

Some of the prominent landmarks on the engineering side include the Blue Earth Workshop — which, in addition to being among the foremost centres of learning techniques in workshop technology, also has the dubious distinction of having been used by students affected by the naxalite violence to manufacture blow guns, the “ gachchtola ”, the “ jheel paar ”, ashirwad canteen ( now converted into the SURUCHI canteen ), the windmill and the “ green zone ”.

Some more advanced knitting techniques create a surprising variety of complex textures.

Some of these new techniques have been used successfully for small-scale commercial and important research applications.

Some producers adopted motor-powered tappers and metal tubing systems to convey sap from the tree to a central collection container, but these techniques were not widely used.

Some experimented with new techniques, such as faster beats and the use of side steps in the dance ; this latter innovation formed the foundation of cha-cha-cha, and was the result of Jorrin's experimentation.

Some sophisticated firing techniques were used from Period VI and VII and an area reserved for the pottery industry has been found at mound MRI.

Some 45 frequencies are assigned for use primarily by dominant Class 1, -- A or Class 1, -- B clear-channel stations, designed to operate with adequate power and to provide service -- both groundwave and ( at night ) skywave -- over large areas and at great distances, being protected against interference to the degree necessary to achieve this objective.

Some are played primarily throughout one geographic region, and others add new tactical elements to the game.

Some Christian denominations hold that salvation depends upon transformational faith in Jesus, which expresses itself in good works as a testament ( or witness ) to ones faith for others to see ( primarily Eastern Orthodox Christianity and Roman Catholicism ), while others ( including most Protestants ) hold that faith alone is necessary for salvation.

Some layout engines such as Trident / MSHTML and Presto are associated primarily or exclusively with a particular browser such as Internet Explorer and Opera respectively.

Some philosophers think there is an important distinction between " knowing that ," " knowing how ," and " acquaintance-knowledge ," with epistemology primarily interested in the first.
