Next: Adding more disk space Up: Allocating disk space Previous: Space requirements . I used to have a 109 MB hard disk. Now I am using a 330 MB hard disk. I'll explain how and why I partitioned these disks. ... First, I used to run MS-DOS together with Linux. For that, I needed about 20 MB of hard disk, or just enough to have MS-DOS, a C compiler, an editor, a few other utilities, the program I was working on, and enough free disk space to not feel claustrophobic. ...

... Instead of putting code in each application you write to control each device, you share the code between applications. ... Within the kernel, there are a set of functions, registered with the filesystem, which are called to handle requests to do I/O on ``device special files,'' which are those which represent devices. ... This chapter explains how to write any type of Linux device driver that you might need to, including character, block, SCSI, and network drivers. ...

... A lot Chinese names are degenerate. For example, it is hard to identify the person by just reading S. Xu.

This paper, presents the fifos and shared memory virtual interface (VIs) that allow LabVIEW to communicate and share (bulk) data with the real-time core. ... For the work described in this paper, the interested reader will require the common mbuff 0.7.11 and fifos 0.52 packages built under either the RTLinux 2.23 or RTAI 1.34 kernel patches to Linux 2.2.145. ...

... BEHR is a standalone command-line C program designed to quickly estimate the hardness ratios and their uncertainties for astrophysical sources. It is especially useful in the Poisson regime of low counts, and computes the proper uncertainty regardless of whether the source is detected in both passbands or not. ... src are the counts within the source region, and *bkg are counts within the background region. ... soft-band counts in source region . hard-band counts in source region . ...

A descriptor , also commonly called a file handle is an object that a program uses to read or write an open file, or open network socket, or a variety of other devices. ... The operating system enforces a limit on the number of descriptors that a program can have open at a time. ... One is a kernel limitation, depending on your operating system you will either be able to tune the number of descriptors available to higher numbers (this is frequently called FD_SETSIZE ). ...
