This means that this report will be lacking in such things as product specific- and classified information. I would like to thank a few people who made it possible for me to successfully complete my internship at the Platform Technologies Group at Apple. First off, the people who made this internship possible, John Kelley, Ben Byer and my manager John Wright. Mike Smith, Tom Duffy and Anthony Yvanovich for helping me through the rough patches of this project. And the entirety of Core OS for making my stay an unforgettable experience. 3 Introduction About the Platform Technologies Group As it was described by a manager: “We do the plumbing, if we do our jobs right, you never see it.”. The Platform Technologies Group, a subdivision of the Core OS department, works on the embedded platforms that Apple maintains. Here, platforms are brought up and the embedded kernel and lower level support for the platforms is maintained. -
Active-Active Firewall Cluster Support in Openbsd
Active-Active Firewall Cluster Support in OpenBSD David Gwynne School of Information Technology and Electrical Engineering, University of Queensland Submitted for the degree of Bachelor of Information Technology COMP4000 Special Topics Industry Project February 2009 to leese, who puts up with this stuff ii Acknowledgements I would like to thank Peter Sutton for allowing me the opportunity to do this work as part of my studies at the University of Queensland. A huge thanks must go to Ryan McBride for answering all my questions about pf and pfsync in general, and for the many hours working with me on this problem and helping me test and debug the code. Thanks also go to Theo de Raadt, Claudio Jeker, Henning Brauer, and everyone else at the OpenBSD network hackathons who helped me through this. iii Abstract The OpenBSD UNIX-like operating system has developed several technologies that make it useful in the role of an IP router and packet filtering firewall. These technologies include support for several standard routing protocols such as BGP and OSPF, a high performance stateful IP packet filter called pf, shared IP address and fail-over support with CARP (Common Address Redundancy Protocol), and a protocol called pfsync for synchronisation of the firewalls state with firewalls over a network link. These technologies together allow the deployment of two or more computers to provide redundant and highly available routers on a network. However, when performing stateful filtering of the TCP protocol with pf, the routers must be configured in an active-passive configuration due to the current semantics of pfsync. -
Join Together Read Me.Rtfd
Join Together v5.1.5 AppleScript Studio Application for iTunes Find more free AppleScripts and info on writing your own at Doug's AppleScripts for iTunes. This application will enable you to join the files of selected iTunes tracks together with Quick Time and export them as a single AAC file/track. Optionally, with Apple's "Chapter Tool" application installed, you can then create a "chapterized" audio file of the exported AAC file. Requires: Mac OS 10.4 ("Tiger") or better iTunes 4.9 or better (version 6 or better preferred) QuickTime Player v7.0 or better Chapter Tool required for creating "chapterized" AAC's This application is Donationware. If you use it and like it please consider making a donation to support my AppleScripting efforts. Click here for more info. Installation: Place the Join Together application anywhere it is conveniently accessible. The Applications folder is as good a place as any. Because Join Together is an application I do not recommend placing it in your iTunes Scripts folder since it cannot be accessed from the iTunes Script menu. (See the accompanying "Make A Join Together Launch Script" to create a small AppleScript that can launch Join Together from the iTunes Script menu.) QuickTime v7.x.x In order to export joined files as AAC files you must have QuickTime Player 7 or better. Chapter Tool "Chapter Tool" is a command-line application that assists with creating "chapterized" audio files, (a.k.a enhanced audio files). This script utilizes it to create such files from your joined tracks. You can download the Chapter Tool application (currently Beta 2.0b8 as of this writing) by clicking on the URL clip provided in this script's download package. -

Running EDIUS 7 on an Apple Mac Computer Under Boot Camp Steve Leeflang March 2015 APPLICATION NOTE RUNNING EDIUS 7 on an APPLE MAC COMPUTER UNDER BOOT CAMP
Running EDIUS 7 on an Apple Mac Computer under Boot Camp Steve Leeflang March 2015 APPLICATION NOTE RUNNING EDIUS 7 ON AN APPLE MAC COMPUTER UNDER BOOT CAMP Installing Boot Camp pple’s free Boot Camp utility permits installation of Microsoft’s Windows 7 or 8 64-bit operating system just as if it were being installed normally on other types of PCs. When running Windows under Boot Camp the user has access to all editing hardware and software, A including the Grass Valley, a Belden Brand, EDIUS nonlinear editing program. Important Note: Please refer to Apple’s website to find out which version of Boot Camp and Windows are supported on your Mac. https://support.apple.com/en-us/HT204048 Before starting the installation, check for updates for the Mac. Go to the Apple Menu > Updates and in- stall all available updates. Installation: In OS X, launch the Boot Camp Assistant (from the “other” folder in Launch Pad). Next, create a partition. Create a second partition for Windows. www.grassvalley.com 2 APPLICATION NOTE RUNNING EDIUS 7 ON AN APPLE MAC COMPUTER UNDER BOOT CAMP Installing Boot Camp (Cont.) The user then decides how much space they want to allocate to Windows. EDIUS, with all its third-party applica- tions, requires around 6 GB of hard disk space for installation. Depending on the available free disk space, it is a good idea to have at least 20 to 32 GB for the Windows partition. (A second disk can be chosen especially for Windows.) To change the allocated space for the Windows partition, click the small divider between Mac OS X and Windows, and drag it to the left. -
