A property and description of something that could easily draw blood. Generally regarded as bad to fall on. Musically, it is when a certain note has a slightly higher pitch than what is commonly considered "standard", like playing A442 as opposed to A440.

A Japanese electronics company. They make cool stuff like Minidisc players, TVs and Video Cameras. Their stuff is decent quality, but not quite up to the level of good Sony Stuff. I own a MD-MT15 Minidic Player/Recorder from them and a VLH-100 Video Camera, as well as an old TV. I'm pretty pleased with their stuff. They also are the largest manufacturer of LCD panels.

In music notation, a sharp is a tic-tac-toe symbol which indicates that a certain note should be raised a half step. If used in the key signature, it means that note should be raised a half-step whenever it is encountered; if used as an accidental, it means that only that note should be changed.

The half-step increment applies whether it changes the note to a "white key" or not. For instance, A-sharp is the same as B-flat, but B-sharp is the same as C.

A sharp looks like this, when used in the key signature and as an accidental with a half note:

----| /----#-----------------------------------------------
    |/             # O                                    
   /|    #          |                                      
 |  |  |            |                                      
  \ |  |                                               

It is difficult to convey the actual picture of a sharp in this medium, although mblase makes a strong attempt.

The sharp is virtually the same size as the space between the lines. The part of the sign that is read is the parallelogram inside the tic-tac-toe: it must fill the the space if the sharp is on the space; the line must bisect it if it is one the line.

The name of the Sharp Corp. goes back to the first well-known product of the company, the Ever-Sharp Pencil, which was a rather stylish (even by today's standards) mechanical pencil. SHARP was founded in 1912 by Tokuji Hayakawa - whose heirs can still be found working for SHARP.

Todays product range includes everything from LCD displays to computers, copiers, consumer electronics, cash registers and ultrasonic washing machines. SHARP employs about 60000 people world-wide, a huge amount of them in R&D. (About ten percent of the profit supposedly are spent in SHARP Labs - the companies research brand.)

The currently best-known SHARP product in Hackerdom is most likely the SL-5500 Linux-based PDA, which will even run Nethack.
