The project maintains around 100 virtual appliances, all freely licensed, with daily automatic security updates and backup capabilities. [2] They are packaged in formats for different virtualization platforms, and two builds for installing onto physical media (to non-virtualized hard disk or USB from a hybrid ISO) or onto the Amazon Elastic Compute Cloud.
A dedicated program, the spooler, maintains an orderly sequence of jobs for the peripheral and feeds it data at its own rate. Conversely, for slow input peripherals, such as a card reader , a spooler can maintain a sequence of computational jobs waiting for data, starting each job when all of the relevant input is available; see batch processing .
Location of the "O(1) scheduler" (a process scheduler) in a simplified structure of the Linux kernel. An O(1) scheduler (pronounced "O of 1 scheduler", "Big O of 1 scheduler", or "constant time scheduler") is a kernel scheduling design that can schedule processes within a constant amount of time, regardless of how many processes are running on the operating system.
runit is an init and service management scheme for Unix-like Operating systems that initializes, supervises, and ends processes throughout the operating system. Runit is a reimplementation of the daemontools [3] process supervision toolkit that runs on many Linux-based operating systems, as well as BSD, and Solaris operating systems.
HASP bypassed most operating system services with code specially tailored for efficiency. HASP operated as a single operating system task [1] and used cooperative multitasking internally to run processors to perform tasks such as running card readers, printers, and punches, managing the spool files, communicating with the system operator, and driving multiple communication lines for remote job ...
CUPS 1.1 replaced this interface with an enhanced administration interface that allows users to add, modify, delete, configure, and control classes, jobs, and printers. CUPS 1.2 and later provide a revamped web interface which features improved readability and design, support for automatically discovered printers, and better access to system ...
In March 2011 Novell released SUSE Manager 1.2, based on Spacewalk 1.2 and supporting the management of both SUSE Linux Enterprise and Red Hat Enterprise Linux. [ 19 ] In May 2018, during the openSUSE conference in Prague, it was announced [ 20 ] [ 21 ] that a fork of Spacewalk, called Uyuni , was being created.
The data on a RAID 1 volume is the same as on a normal partition. The RAID information is stored in the last 128kB of the partition. This means, to convert a RAID 1 volume to normal data partition, it is possible to decrease the partition size by 128kB and change the partition ID from fd to 83 (for Linux).
