Screw

A screw is a type of fastener, sometimes similar to a bolt (see Differentiation between bolt and screw below), typically made of metal, and characterized by a helical ridge, known as a male thread (external thread) or just thread. A screw is an inclined plane wrapped around a nail. Some screw threads are designed to mate with a complementary thread, known as a female thread (internal thread), often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects.

A screw will usually have a head on one end that contains a specially formed shape that allows it to be turned, or driven, with a tool. Common tools for driving screws include screwdrivers and wrenches. The head is usually larger than the body of the screw, which keeps the screw from being driven deeper than the length of the screw and to provide a bearing surface. There are exceptions; for instance, carriage bolts have a domed head that is not designed to be driven; set screws often have a head smaller than the outer diameter of the screw; J-bolts have a J-shaped head which is not designed to be driven, but rather is usually sunk into concrete allowing it to be used as an anchor bolt. The cylindrical portion of the screw from the underside of the head to the tip is known as the shank; it may be fully threaded or partially threaded. The distance between each thread is called the "pitch".

Screw (card game)

Screw, Moonshine, or Popcorn is a card game where the players try to be the first to lose all their cards. Like Palase, it is derived from the Finnish card game Paskahousu.

Rules

Chopped and screwed

Chopped and screwed (sometimes called screwed and chopped or slowed and throwed) refers to a technique of remixing hip hop music which developed in the Houston hip hop scene in the 1990s. This is accomplished by slowing the tempo down to between 60 and 70 quarter-note beats per minute and applying techniques such as skipping beats, record scratching, stop-time, and affecting portions of the music to make a "chopped-up" version of the original. DJ Screw is largely recognized as the innovator behind the chopped and screwed genre. DJ Screw's key technique involved playing the same record on both turntables with a delay between them of one beat, and quickly moving the crossfader side to side. This created an effect where words or sounds would be repeated in the music but would still keep the tempo going. A subgenre called ChopNotSlop created by hailmasch"hailmasch has received major attention via Drake's album and the Houston music scene started by SUC.

History

Solid-state drive

A solid-state drive (SSD, also known as a solid-state disk although it contains neither an actual disk nor a drive motor to spin a disk) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology primarily uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives, which permit simple replacements in common applications. Additionally, new I/O interfaces, like SATA Express, have been designed to address specific requirements of the SSD technology.

SSDs have no moving (mechanical) components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) or floppy disks, which contain spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically more resistant to physical shock, run silently, have lower access time, and less latency. However, while the price of SSDs has continued to decline over time, consumer-grade SSDs are still roughly eight to nine times more expensive per unit of storage than consumer-grade HDDs.

SSD (band)

HIDDEN ERROR: Usage of "Instruments" is not recognized

SSD (Society System Decontrol) were a straight edge hardcore (and later heavy metal) band from Boston. They released two records as SS Decontrol and then formally changed their name to SSD. As SSD they released two more records, these with a very heavy metal influenced sound. However the group is often simply referred to, including all its periods, as SSD.

History

Formed by songwriter/guitarist Al Barile (then a machinist at the General Electric plant in Lynn, Massachusetts and a student at Northeastern University), SSD started performing at smaller venues throughout the Greater Boston metropolitan area, like Gallery East, in the summer of 1981. The band quickly gained notoriety within the local music scene for intense, charged performances and the provocative antics of their core group of followers, the Boston Crew.

The original lineup was Al Barile on guitar, Springa (David Spring) on vocals, Jaime Sciarappa on bass and Chris Foley on drums. They released their debut LP The Kids Will Have Their Say on their own X-Claim label in 1982.Ian MacKaye of Minor Threat was a friend and supporter and his Dischord label's logo appeared on the back cover.
