The following quote is from page 4-27 of the MSCP Basic Disk Functions Manual which is part of the UDA50 Programmers Doc Kit manuals: As stated above, the host area of a disk is structured as a vector of logical blocks. From a performance viewpoint, however, it is more appropriate to view the host area as a four dimensional hyper-cube, the four dimensions being cylinder, group, track, and sector. . . . Referring to our hyper-cube analogy, the set of potentially accessible blocks form a line parallel to the track axis. This line moves parallel to the sector axis, wrapping around when it reaches the edge of the hyper-cube. | |
The language provides a programmer with a set of conceptual tools; if these are inadequate for the task, they will simply be ignored. For example, seriously restricting the concept of a pointer simply forces the programmer to use a vector plus integer arithmetic to implement structures, pointer, etc. Good design and the absence of errors cannot be guaranteed by mere language features. -- Bjarne Stroustrup, "The C++ Programming Language" | |
TIRED of calculating components of vectors? Displacements along direction of force getting you down? Well, now there's help. Try amazing "Dot-Product", the fast, easy way many professionals have used for years and is now available to YOU through this special offer. Three out of five engineering consultants recommend "Dot-Product" for their clients who use vector products. Mr. Gumbinowitz, mechanical engineer, in a hidden-camera interview... "Dot-Product really works! Calculating Z-axis force components has never been easier." Yes, you too can take advantage of the amazing properties of Dot-Product. Use it to calculate forces, velocities, displacements, and virtually any vector components. How much would you pay for it? But wait, it also calculates the work done in Joules, Ergs, and, yes, even BTU's. Divide Dot-Product by the magnitude of the vectors and it becomes an instant angle calculator! Now, how much would you pay? All this can be yours for the low, low price of $19.95!! But that's not all! If you order before midnight, you'll also get "Famous Numbers of Famous People" as a bonus gift, absolutely free! Yes, you'll get Avogadro's number, Planck's, Euler's, Boltzmann's, and many, many, more!! Call 1-800-DOT-6000. Operators are standing by. That number again... 1-800-DOT-6000. Supplies are limited, so act now. This offer is not available through stores and is void where prohibited by law. | |
Come, every frustum longs to be a cone, And every vector dreams of matrices. Hark to the gentle gradient of the breeze: It whispers of a more ergodic zone. -- Stanislaw Lem, "Cyberiad" |
