Unreferenced date December 2009 Lowercase code write code can refer to several Unix commands. All known variations of code write code are used to write messages to another user.

The tty argument is only necessary when a user is logged into more than one terminal.

lowercase In Unix like computer operating system s, the code at code command is used to schedule command computing command s to be executed once, at a particular system time time in the future. More precisely, it reads a series of commands from standard input and collects them into one at job which is carried out at a later date. The at job inherits the current environment, so that it is executed in the same working directory and with the same environment variable s set as when it was scheduled. It differs from code cron code which is used for recurring executions e.g. once an hour, every Tuesday, January 1 every year . As with code cron code , many Unix systems allow the administrator to restrict access to the code at code command. code at code can be made to mail a user when done carrying out a scheduled job of theirs, can use more than one job queue, and can read a list of jobs to carry out from a file instead of standard input.

A port of Version 6 Unix to the Interdata 7 32 was completed by Richard Miller and Ross Nealon at Wollongong University , Australia , during 1976 1977. This project was supervised by professor Juris Reinfelds . The resulting system was called Wollongong Interdata UNIX, Level 6 . This distribution also included utilities developed at Wollongong, and later releases had features of V7, notably its C programming language C compiler . Wollongong Unix was the first ever port to a platform other than the PDP series of computers, proving that portable operating systems were indeed feasible, and that C was the language in which to write them.

Unreferenced date December 2009 A write buffer is a type of data buffer . In a CPU cache , a write buffer can be used to hold data being written back from the cache computing cache to Computer data storage Primary storage main memory . This is a variation of write through caching called buffered write through . Use of a write buffer in this manner frees the cache to service read requests while the write is taking place. It is especially useful for very slow main memory in that subsequent reads are able to proceed without waiting for long main memory latency. When the write buffer is full i.e. all buffer entries are occupied , subsequent writes still have to wait until some slots are freed. To further mitigate this stall, one optimization called write buffer merge is proposed. Write buffer merge combines writes that have consecutive destination addresses into one buffer entry. Otherwise, they would occupy separate entries which increases the chance of pipeline stall. Sometimes the terminology victim buffer is also called write buffer. Victim buffer is a buffer that stores dirty evicted lines in write back caches note that write through caches don t write the evicted cache lines back before they get written back to the higher level memory. Besides reducing pipeline stall by not waiting for dirty lines to write back as the original write buffer does, victim buffer also serves as a temporary backup storage when subsequent cache accesses exhibit Locality of reference locality , requesting those recently evicted lines, which are still in the victim buffer.

Unreferenced date November 2006 Write precompensation abbreviated WPcom in the literature is a technical aspect of hard disk design. It is the use of a stronger magnetic field to write data in disk sector sector s that are closer to the center of the disk. In constant angular velocity recording, in which the disk spins at a constant speed no matter where the data is written, the sectors closest to the spindle are packed tighter than the outer sectors and so require a stronger magnetic field to write the data. In the past one of the hard disk parameters stored in a PC s CMOS memory is the WPcom number, a marker of the track where precompensation begins. Modern hard disks rarely access the CMOS memory and internally store the WPcom number if write precompensation is used. DEFAULTSORT Write Precompensation Category Hard disk drives ... more details
