Each number describes the distance of a particular point-location from the origin, or zero. The unit of measure for the distance is arbitrary. 10 9 8 (4.5,7.5) 7 6 s i x a (3,5) - 5 y 4 3 (6,3) 2 1 0 0 1 2 3 4 5 6 7 8 9 10 x - axis Figure 2.2 Here is a simple x-y coordinate system with the coordinates of a few points shown as examples. Coordinates are given as an ordered pair of numbers, with the x-coordinate first. The origin is the lower left, at (0,0). The reference lines are the x and y axes. All grid lines are drawn parallel to the two reference lines. The purpose of the grid is to make it easier to make distance measurements between a location-point and the reference lines. 5 4 3 (2,3) 2 s 1 i x a (-2,0) - 0 y -1 -2 (1,-2) -3 -4 -5 -5 -4 -3 -2 -1 0 1 2 3 4 5 x - axis Figure 2.3 A more general coordinate grid places the origin (0,0) at the center of the grid. The coordinates may have either positive or negative values. The sign merely indicates whether the point is left or right (x), or above or below (y) the axis. -
De-Anonymizing Live Cds Through Physical Memory Analysis
De-Anonymizing Live CDs through Physical Memory Analysis Andrew Case [email protected] Digital Forensics Solutions Abstract Traditional digital forensics encompasses the examination of data from an offline or “dead” source such as a disk image. Since the filesystem is intact on these images, a number of forensics techniques are available for analysis such as file and metadata examination, timelining, deleted file recovery, indexing, and searching. Live CDs present a serious problem for this investigative model, however, since the OS and applications execute in a RAM-only environment and do not save data on non-volatile storage devices such as the local disk. In order to solve this problem, we present a number of techniques that support complete recovery of a live CD’s in-memory filesystem and partial recovery of its deleted contents. We also present memory analysis of the popular Tor application, since it is used by a number of live CDs in an attempt to keep network communications encrypted and anonymous. 1 Introduction Traditional digital forensics encompasses the examination of data from an offline or “dead” source such as a disk image. Under normal circumstances, evidence is obtained by first creating an exact, bit-for-bit copy of the target disk, followed by hashing of both the target disk and the new copy. If these hashes match then it is known that an exact copy has been made, and the hash is recorded to later prove that evidence was not modified during the investigation. Besides satisfying legal requirements, obtaining a bit-for-bit copy of data provides investigators with a wealth of information to examine and makes available a number of forensics techniques. -

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations. -
Linux Versions
Linux Versions The Linux "product" is provided in a large number of different versions, known as "distributions," each of which retains the core kernel and GNU tools. Additionally, a variety of common tools (such as KDE, Apache, and Samba) are backed with a collection of additions and service options that meet a particular market niche. Red Hat holds the largest Linux installed base in the US, Novell SUSE Linux in Europe, and TurboLinux (based in Japan) in Asia-Pacific. Mainstream distributions--i.e. commercial applications fully supported by their vendor—have typical license and maintenance fees, just as any other commercial software applications would, while community supported distributions tend to be free to users. Table below lists the best-known Linux distributors, as well as companies that support multiple versions of Linux versions developed by others.

Technology Overview New Features Backupedge
Technology Overview - BackupEDGE™ Introduction to the New Features in BackupEDGE 3.x Technology Overview BackupEDGE has a long history of providing reliable data protection for New Features many thousands of users. As operating systems, storage devices and BackupEDGE 3.x usage needs and tendencies have changed over the years, it has continuously met the challenge of providing inexpensive, stable backup and disaster recovery on a variety of UNIX and Linux platforms. Clients routinely find new and clever ways to utilize products. Storage devices have taken on new and exciting features, and incredible capacities. Products designed years ago had built-in limits that were thought to be beyond comprehension. Today, these limits are routinely exceeded. The need for data security is even more apparent. We’re constantly asking our To continue to meet the evolving needs of our clients, we are always clients what tools our asking what features of our products they find most useful, what products need to serve them improvements we can make, and what new requirements they have. better. We’ve used this knowledge to map out new product strategies designed to anticipate the needs of the next generation of users, systems and storage products. This has resulted in the creation of BackupEDGE 3.x, with a combination of internal improvements, new features and enhanced infrastructure designed to become the backbone of a new generation of storage software. Summary of Major Changes and Additions BackupEDGE 3.x features include: • Improvements to partition sizing, UEFI table cleanup after DR, and SharpDrive debugging (03.04.01 build 3). • Support for Rocky Linux 8.4 and AlmaLinux 8.4 (03.04.01 build 2). -
