About Xcode Developer Tools
Xcode 3.1.4 developer tools for Mac OS X v10.5 Contents
Introduction Compatibility with Mac OS X Versions What's New Installation Deprecation Notice

Introduction
Xcode 3.1.4 is an update and bug fix release to the Mac OS X 10.5 Leopard developer tools. This release includes new, optional GCC and LLVM compilers, updated project assistant, a simplified toolbar, and additional bug fixes and security enhancements. You do not need to install this package if you have already installed the iPhone SDK for iPhone OS 3.0. The complete Xcode developer tools are included as part of the iPhone SDK installation (download available separately). We encourage developers to join the Apple Developer Connection. It provides the most convenient access to Apple Inc. development resources, technical support and pre-release software. For information visit http://developer.apple.com/.

Compatibility with Mac OS X Versions
Xcode 3.1.4 is compatible with Intel and PowerPC Macs running Mac OS X 10.5 Leopard. Xcode 3.1.4 supports development targeting Mac OS X v10.3 Panther and Universal applications for Mac OS X v10.4 Tiger and Mac OS X v10.5 Leopard using the Mac OS X SDK support.

What's New
• • • • • SDK support for targeting non-Mac OS X platforms, including iPhone OS SDK. GCC 4.2 & LLVM GCC 4.2 optional compilers for use with Mac OS X 10.5 SDK Updated assistants to create new projects, targets, and source files Toolbar uses a single popup to choose platform, target, and debug/release Integrated SCM support now works with Subversion 1.5

About SDKs Xcode 3.1 extended the concept of an SDK (software development kit) to enable Xcode to build, debug, and deploy applications for platforms completely different from that of the host computer. This is possible by bundling a complete set of low-level compilers and tools within the SDK, in addition to platform frameworks. Within Xcode you can choose specific Mac OS X SDKs to create applications that run on particular versions of Mac OS X, or use the iPhone SDK to build applications for the iPhone Simulator, the iPhone, or iPod touch. The tools included with the SDK will upload your application to a device, and debug directly from the IDE. Xcode is included as part of the iPhone SDK installer, and is also available separately with only the Mac OS X SDKs for Mac-only developers. New in Xcode IDE • The assistant interface has been completely revamped, making it easier to create "New Project", "New Target", and "New File" resources. This release of Xcode also adds new assistant templates for both Mac OS X and iPhone OS applications. A new Overview toolbar item lets you see and set the project's active Target, Configuration, Executable, Architecture, and SDK with a single control. It is now possible to set a global "override" SDK as the Active SDK, making it easy to test the build of your entire project against a different platform. New interface shortcuts have been added to the Build Setting inspectors making it easy to set the desired compiler, architectures, and SDKs You can now add Libraries and Frameworks directly into the Target window and relate them to the project's SDK. The Xcode UI now allows you to designate a library or framework as weaklinked, to support building with newer SDKs while targeting older OS versions. New "Edit all in scope" option within the Xcode source editor makes it easy to update all instances of the selected symbol within the current scope of code. You can now have conditional build settings assigned for any combination of architecture and SDK. LLVM GCC 4.2 is a new optional compiler based on the LLVM.org open source project. LLVM GCC 4.2 provides an LLVM-based back-end optimizer using the GCC 4.2 front-end parser. This compiler is both source and binary compatible with GCC 4.2 and requires the Mac OS X 10.5 SDK or "Current OS" SDK. GCC 4.2 is a new optional compiler with stricter C and C++ language enforcement, security enhancements, performance optimizations, and bug fixes over GCC 4.0. Requires the Mac OS X 10.5 SDK or "Current OS" SDK

• • • • • • • •



New in Interface Builder 3.1 • • • • • • New drag & drop functionality allows easily re-parenting objects with the normal drag gesture The document outline view has been enhanced to support full drag re-ordering. A new string table interface allows localizers to make quick text changes across documents. Generates XIB files that are more diff friendly while retaining full backwards compatibility with Interface Builder 3.0. Now supports previewing image resource content in Carbon controls. You can now use Dashcode to create web applications optimized for the iPhone, as well as Dashboard widgets.

New in Dashcode

Installation
The Xcode installer provides these main options for configuring the installation: • Developer Tools Essentials. Contains the essential components of Xcode. It’s installed in /Developer by default or another directory of your choice, including external volumes. System Tools. Optional tools, includes Shark and other CHUD performance tools. Its components are always placed in /Developer. UNIX Development Support. Optional command-line tools used for UNIXbased development. Its components are always placed in /usr.

• •

Throughout this document refers to the path in which the Developer Tools Essentials components are installed. You can now have both Xcode 3.1 and Xcode 3.0 installed. The Xcode installer supports installing multiple versions of the Developer Tools Essentials components on Mac OS X v10.5. You can move or rename the directory, but must not alter its internal structure. If you need to refer to a developer application from a different directory, it is best to use an alias or symbolic link for the full path. NOTE: Only one version of the System Tools and the UNIX Development Support components can be installed on a computer at a time. The last installed set of these components replaces any previously installed set.

Installing Xcode Developer Tools NOTE: if you have installed the iPhone SDK package you may already have Xcode installed and may not need to install this package. The Xcode installer has been changed for Leopard to allow for simple installation of the developer tools. This reorganized structure gives you all the options you need when installing, and obviates the need to install content from individual packages. The installation choices in the "Customize..." panel have been reorganized into these items: • Developer Tools Essentials - Xcode, Interface Builder, Instruments, Dashcode, Quartz Composer, GCC 4.0.1, GCC 4.2, LLVM GCC 4.2, and other essential developer tools. Also installs the Mac OS X 10.4 (Universal) and Mac OS X 10.5 SDKs, as well as sample source code. System Tools - CHUD tools (including Shark) for measuring and optimizing software performance on Mac OS X, hardware bringup, and system benchmarking. Also includes support for enabling distributed builds and Instruments/DTrace integration. Note: the CHUD tools are installed onto the boot volume at /Developer. UNIX Development Support - Optional content to allow command-line development from the boot volume. Installs a duplicate of the GCC compiler and command line tools included with the Developer Tools Essentials package into the boot volume. It also installs header files, libraries, and other resources for developing software using Mac OS X into the boot volume. This package is provided for compatibility with shell scripts and makefiles that require access to the developer tools in specific system locations. This content is not relocatable and will only be installed onto the boot volume. Mac OS X v10.3.9 Support - Adds support for developing applications that target Mac OS X v10.3.9 APIs. Includes the Apple version of the GCC 3.3 compiler and the Mac OS X v10.3.9 SDK. Note: GCC 3.3 is not relocatable and is installed on the boot volume. This package is not selected by default. WebObjects - Installs WebObjects development tools, examples, and documentation. Note: WebObjects is not relocatable and is installed onto the boot volume at /Developer. This package is not selected by default.









Step-by-Step Instructions Note: By default, all versions of Xcode are installed in /Developer with previous versions automatically upgraded. If you want to keep a previously installed version of Xcode and still install Xcode 3.1, you must either do a "Custom Install" of Xcode 3.1 and specify a new directory name (e.g. Xcode3.1) or you must move the preexisting /Developer directory to a new name (e.g. Xcode3.0) before you install Xcode 3.1.4. See step 5 below.

1. 2. 3. 4. 5.

Boot into a partition with the Mac OS X v10.5.x installed. Download the Xcode 3.1 Developer DVD software. Double-click on XcodeTools.mpkg. Follow the instructions in the Installer. To install Xcode 3.1.4 in a directory other than the default /Developer, you must specify a new directory name on the "Custom Install" pane; e.g. Xcode3.1.4. ⁃ ⁃ ⁃ ⁃ ⁃ Select the folder icon under "Location" next to the "Developer Tools Essentials" package name. Select "Other..." at the top of the pop-up. Navigate to the location for the new folder. Select "New Folder". Enter a folder name in the "New Folder" window; e.g. Xcode3.1.4. Select "Create". Finally, select "Choose" in the "Install Xcode Tools" pane.

6. 7.

If you need to install Mac OS X 10.3.9 Support or WebObjects, you must select "Customize", and check those packages on the "Custom Install" panel. Authenticate as the administrative user. The first user you create when setting up Mac OS X has administrator privileges by default.

Once you have installed the Xcode developer tools, you can access the documentation by launching Xcode and choosing any of the items in the Help menu. Developer applications such as Xcode, Instruments, and Interface Builder are installed in /Applications. Uninstalling Xcode Developer Tools To uninstall Xcode developer tools on the boot volume along with the directory, from a Terminal window type: $ sudo /Library/uninstall-devtools --mode=all If you just want to remove the underlying developer content on the boot volume, but leave the directory and supporting files untouched, from a Terminal window type: $ sudo /Library/uninstall-devtools --mode=systemsupport If you just want to just remove the UNIX development support on the boot volume, but leave the directory and supporting files untouched, from a Terminal window type: $ sudo /Library/uninstall-devtools --mode=unixdev Finally, to just uninstall the directory you can simply drag it to the trash, or from a Terminal window type: $ sudo /Library/uninstall-devtools --mode=xcodedir

NOTE: The uninstaller that ships with previous versions of the Xcode developer tools will not clean everything off of your system properly. You should either use the one provided on the Mac OS X v10.5 Leopard DVD, or you should use the one installed when you installed the Xcode 3.1.4 developer tools.

Deprecation Notice
NOTE: As of the release of Xcode 2.4, the Cocoa Java bridge has been deprecated. This means that, while still supported with Xcode 2.4, starting with this release the Cocoa Java bridge is no longer supported. Due to this, the following additional WebObjects developer applications have been removed: EOModeler EOModeler Plugin WebObjects Builder WebServices Assistant RuleEditor WOALauncher Xcode Java bridge templates have been deprecated, and should not be used for new Java bridge-based development. The following directories inside the Xcode are deprecated and will be removed in a future version of the Xcode developer tools: /Tools (content will move to /usr/bin) /Makefiles (content will move to /usr/share/makefiles in a future release) /Private (content will be removed in a future release)

...Ransomware Discuss the threat When infected restricts you to access to a computer system. This will become more refined in its targets and methods. Experts predict that the variants of ransomware that hurt the security software that are installed within a computer may particularly target the endpoints which sign up with cloud-based storage solutions like Google Drive, Dropbox, OneDrive and many more. On detecting the endpoint, ransomware will exploit the stored personal credentials of the logged-in user and will even infect the cloud storage that is backed up. McAfee has warned that ransomware attackers will try out as many ways possible to shell out ransom payments from their victims. Degree of damage The most advanced and most damaging ransomware in the wild at the moment, specifically targeting U.S. businesses and individuals. It's a $70 million per year criminal enterprise. Its magnitude is now confirmed by law enforcement. Some quick math shows $18,145 in costs per victim, caused by network mitigation, network countermeasures, loss of productivity, legal fees, IT services, and/or the purchase of credit monitoring services for employees or customers. As you can see, the total costs of a ransomware infection goes well above just the ransom fee itself, which is usually around $500 but can go up to $10,000. What it attacked Ransomware is a type of malware that infects a computer and restricts a user’s access to the infected computer. This type of malware...

...program consists of one or more source files. Each source file is called .java, where is the name of the class contained in that source file and .java is the extension that identifies the file as a Java source code file. In general, each source file contains one class. The name of the class must match the name of the file (without the extension) exactly. To execute a Java program, you first need to compile the source code into byte code. Byte code files have the name .class. If you’re working from the shell, this is done using the javac command (where “c” is for compiler). Usually we will be compiling using the Xcode IDE. Once compiled, the program is executed using the Java interpreter (a.k.a. the Java Virtual Machine or JVM). From the shell, the JVM is invoked with the “java” command. Again we will usually be doing this with the Build and Go or Debug options of the Xcode IDE. A Java program must have a routine called main(), which is the starting point for program execution. main() will always look something like this: public static void main (String args[]) { // insert code here... System.out.println("Hello World!"); } Source Code Formatting Keep in mind the following when writing Java source code: Java is case sensitive (“foo”, “Foo”, and “fOO” are all considered to be different in Java). • Every line of code in Java must end in a semi-colon (“;”). • Java doesn’t care about white space (line breaks, tabs, etc.) but consistent and thoughtful use of white space makes code much...

This assignment must be submitted using the submit script (see the class website for details) by the end of the day next Wednesday. You may submit it multiple times if you wish. Only the last submission will be counted. For example, it might be a good idea to go ahead and submit it after you have done the walk-through and gotten that part working. If you wait until the last minute to try to submit and you have problems with the submission script, you’ll likely have to use one of your valuable late days. Be sure to check out the Hints section below! Materials • Before you start this assignment, you will need to download and install the iOS SDK and Xcode 4 from http://developer.apple.com or using the App Store on Mac OSX. It is critical that you get the SDK downloaded and functioning as early as possible in the week so that if you have problems you will have a chance to talk to the CA’s and get help.

HARYANA COLLEGE OF TECHNOLOGY AND MANAGEMENT, KAITHAL-136027 Session (Aug - Dec 2010) SUBMITTED BY: SUBMITTED TO: MAYUR BHOLA Mr. Arvind Kumar 7th semester [C.S.E. 1707372 Department] ABSTRACT iOS is Apple's mobile operating system developed originally for the iPhone, and later deployed on the iPod Touch and iPad as well. It is derived from Mac OS X, with which it shares the Darwin foundation, and is therefore a Unix-like operating system, by nature. In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system uses roughly 500 megabytes of the device's storage. Version 4, announced in April 2010, introduced multitasking as well as several business-oriented features, including encryption for email and attachments. At the WWDC 2010 keynote on June 7, 2010, Apple announced that iPhone OS had been renamed iOS. Apple licenses the trademark for "iOS" from Cisco Systems (who own IOS), the same company with which Apple had earlier settled a dispute over the "iPhone" trademark...

PC which stands for “Personal Computer” these will be any IBM-Based running computer. That brings us to our first major difference where Mac can only be sold by Apple, PC can be sold anywhere, because of this PC usually are much cheaper then Mac’s. Another big difference would be the applications available on each system. PC would have your common MS Office, Internet Explorer, Media Player, Media Center, Windows Defender, SkyDrive, VLC media player, Chrome browser. Mac on the other hand has a complete different set of popular apps such as iLife, iWork, Xcode, iTunes, Time Machine, Safari, Mac App Store, FaceTime, Game Center, Photo Booth, Chrome browser, Quick Time. Where Mac can open almost all PC files and can coexist on local networks with PCs Such as doc, .exe, .xls, and others. Software exists for other file types. Mac can also run Windows for 100% compatibility. PC cannot open Mac-based files but if proper software is downloaded there is a possibility you can read or even write Mac-based files. If you are looking more for a gaming system a PC would be the better.

...------------------------------------------------- Essay on “Google Android OS vs. Apple iOS” The competition between Google Android and Apple iOSis one of the most talked after wars in mobile gadget platforms. The Google Android platform is increasingly becoming dominant in the smartphones and tablets market. Nokia, a once leading company in the mobile phone market is slowly entering the smartphone market with a new range of Lumia smartphones powered by Windows 8 mobile as it phases out its range of Symbian powered smartphones. Equally, Motorola Mobility is trying to gain a share of the market by increasing its product portfolio of smartphones in the Droid family. The Android Operating System powers the Droid range of smartphones. Samsung is by far the largest mobile manufacturing company in the world with a full range of Android powered smartphones in the Galaxy family. The recent entry of the Samsung Galaxy SIII heightened the competitive advantage of the Android Software Platform based on the Android 4.0 (Ice Cream Sandwich) software. With HTC,Blackberry OS, and Microsoft Mobile as a distant competitors, the war is clearly not between mobile phone manufacturers but the war is between software manufacturers, and in this case,Apple iOS and Google Android (Katie, 2012). Currently, the competition between Apple iOS and Google Android is so close such that it becomes difficult to tell the superior operating system (Ian, 2011).
