  • Connecting to Cat5 Via X2go from Macos Before Connecting to Cat5 the First Time, Please Follow the “First Time Only” Steps Below
    Brought to you by DES Computing Services Questions? [email protected] Connecting to Cat5 via X2Go from macOS Before connecting to Cat5 the first time, please follow the “First Time Only” steps below. Connecting to Cat5 1. From the Applications menu in Finder, run the “x2goclient” application. 2. Click on the white box on the right that says “cat5.” 3. Enter your Cat5 password as prompted and click OK. 4. The first time you connect, it will ask if you trust the host key. To verify the secure connection, check that the provided “hash” exactly matches one of these lines: • 5e:c1:1a:7a:3d:07:72:64:d3:fc:fe:0a:cc:c5:0f:c8:d1:92:aa:0a • 55:87:cd:ef:80:dc:9d:e8:1d:14:87:27:40:00:01:4a If it matches one of those, then click “Yes” to connect. If it doesn't match either of them, then please check Cat5 Host Key Fingerprints on the DES website for more possible hash values. Do not accept an unverified host key! Disconnecting from Cat5 1. To properly close your session, click on the “System” menu (within the Cat5 desktop) and then click “Log out <name>...” 2. If you just close the window, it will pause your session. You should be able to reconnect later to resume where you left off, but sometimes this might not work. To be safe, follow step 1. First Time Only Steps Install XQuartz You must have the “XQuartz” X-Window system installed before you install X2Go. You may have already installed it for another class.

  • Chapter 1. Origins of Mac OS X
    1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years.

  • Building an Openstep Application by Michael Rutman, Independent Consultant
    Building an OpenStep Application by Michael Rutman, independent consultant Is it really as easy to program in OpenStep OpenStep and NEXTSTEP In 1985, Steve Jobs left Apple and formed NeXT. He found the latest technologies and brought together a team of developers to turn the newest theories into realities. To verify the new technologies, during development Steve would often stop development and have the entire team use the system they were creating. Several existing apps were created during these day or week long kitchens. More importantly, each developer knew how the framework would be used. If developers had a hard time using an object during a kitchen, they knew they had to rework that object. The system they created was called NEXTSTEP. NEXTSTEP has several layers, and each layer was state of the art in 1985. In the 12 years since Steve picked these technologies, the state of the art may have moved, but not advanced. The underlying OS is a Mach mini-kernel running a unix emulator. For practical purposes, Mach is a flavor of BSD unix. However, the Mach mini-kernel offers programmers a rich set of functionality beyond what unix provides. Most of the functionality of Mach is wrapped into the NEXTSTEP framework, so programmers get the power and flexibility of Mach with the ease of use of NEXTSTEP. Sitting on top of Mach is Display Postscript. Postscript, the language of printers, is a nice graphics language. NeXT and Adobe optimized Postscript for displaying on the screen and produced a speedy and powerful display system. NeXT's framework hides most of the Postscript, but if a programmer wants to get into the guts, there are hooks, called pswraps, to work at the Postscript level.

  • Xfree86® on Darwin and Mac OS X Torrey T
    XFree86® on Darwin and Mac OS X Torrey T. Lyons 15 December 2003 1. Introduction XFree86, a freely redistributable open-source implementation of the X Window System, has been ported to Darwin and Mac OS X. This document is a collection of information for anyone running XFree86 on Apple’s next generation operating system. Most of the current work on XFree86 for Darwin and Mac OS Xiscentered around the XonX project at SourceForge. If you areinterested in up-to-date status, want to report a bug, or are interested in working on XFree86 for Darwin, stop by the XonX project. 2. Hardware Supportand Configuration The X window server for Darwin and Mac OS Xprovided by the XFree86 Project, Inc. is called XDarwin. XDarwin can run in three different modes. On Mac OS X, XDarwin runs in parallel with Aqua in full screen or rootless modes. These modes arecalled Quartz modes, named after the Quartz 2D compositing engine used by Aqua. XDarwin can also be run from the Darwin con- sole in IOKit mode. In full screen Quartz mode, when the X Window System is active, it takes over the entirescreen. Youcan switch back to the Mac OS Xdesktop by holding down Command-Option-A. This key combination can be changed in the user preferences. From the Mac OS Xdesktop, click on the XDarwin icon in the Dock to switch back to the X window system. (You can change this behavior in the user preferences so that you must click the XDarwin icon in the floating switch window instead.) In rootless mode, the X window system and Aqua shareyour display.
