Memory Management and Garbage Collection
Overview Memory Management Stack: Data on stack (local variables on activation records) have lifetime that coincides with the life of a procedure call. Memory for stack data is allocated on entry to procedures ::: ::: and de-allocated on return. Heap: Data on heap have lifetimes that may differ from the life of a procedure call. Memory for heap data is allocated on demand (e.g. malloc, new, etc.) ::: ::: and released Manually: e.g. using free Automatically: e.g. using a garbage collector Compilers Memory Management CSE 304/504 1 / 16 Overview Memory Allocation Heap memory is divided into free and used. Free memory is kept in a data structure, usually a free list. When a new chunk of memory is needed, a chunk from the free list is returned (after marking it as used). When a chunk of memory is freed, it is added to the free list (after marking it as free) Compilers Memory Management CSE 304/504 2 / 16 Overview Fragmentation Free space is said to be fragmented when free chunks are not contiguous. Fragmentation is reduced by: Maintaining different-sized free lists (e.g. free 8-byte cells, free 16-byte cells etc.) and allocating out of the appropriate list. If a small chunk is not available (e.g. no free 8-byte cells), grab a larger chunk (say, a 32-byte chunk), subdivide it (into 4 smaller chunks) and allocate. When a small chunk is freed, check if it can be merged with adjacent areas to make a larger chunk. Compilers Memory Management CSE 304/504 3 / 16 Overview Manual Memory Management Programmer has full control over memory ::: with the responsibility to manage it well Premature free's lead to dangling references Overly conservative free's lead to memory leaks With manual free's it is virtually impossible to ensure that a program is correct and secure. -

Memory is reclaimed by deleting regions, freeing all objects stored therein. Our compiler for C with regions, RC, prevents unsafe region deletions by keeping a count of references to each region. RC's regions have advantages over explicit allocation and deallocation (safety) and traditional garbage collection (better control over memory), and its performance is competitive with both|from 6% slower to 55% faster on a collection of realistic benchmarks. Experience with these benchmarks suggests that modifying many existing programs to use regions is not difficult. An important innovation in RC is the use of type annotations that make the structure of a program's regions more explicit. These annotations also help reduce the overhead of reference counting from a maximum of 25% to a maximum of 12.6% on our benchmarks. -

Ipad Voiceover (VO) Controller
RJ Cooper & Assoc., Inc. 1-800-RJCooper 949-582-2571 Fax: 949-582-3169 Internet: www.rjcooper.com Email: [email protected] iPad VoiceOver (VO) Controller This Controller allows control over those apps that are "VoiceOver-Compliant." This is not all apps! In fact, there are probably only several hundred apps that are VO-compliant. Most are not. Fortunately, and most importantly, most of Apple's are: Camera, Photos, Music, Messages, Notes, Mail, iBooks and several others. "VoiceOver" is a technology that Apple created for Macs, then its i-devices, for blind people to be able to hear what's under their finger. To find out if an app is VO-compatible, and also, to make my VO Controller work with your i-device: 1) Settings; 2) General; 3) Accessibility (scroll down to it); 4) VoiceOver; 5) Turn it on and wait and you will hear it. Now move your finger around slowly and things under your finger will highlight and speak. To activate the selected item, double-tap anywhere on the screen (remember that!). To scroll with VO, use 3 fingers. And that's how VO is supposed to work. Now press your Home button, and launch one of your desired apps, and move your finger around. Do things get highlighted and spoken? If so, then you're good to go! If not, you can write to the developer and beg ;-) But Apple soon discoverd that blind people don't use a mouse or their finger; they use a keyboard with keyboard "shortcuts," that is combinations of keys to navigate and hear their screen. -

Ios SDK Release Notes for Ios 8.0 Beta 5
iOS SDK Release Notes for iOS 8.0 Beta 5 Important: This is a preliminary document for an API or technology in development. Apple is supplying this information to help you plan for the adoption of the technologies and programming interfaces described herein for use on Apple‑branded products. This information is subject to change, and software implemented according to this document should be tested with final operating system software and final documentation. Newer versions of this document may be provided with future betas of the API or technology. Contents: Introduction Bug Reporting Notes and Known Issues Introduction iOS SDK 8.0 provides support for developing iOS apps. It is packaged with a complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others. With this software you can develop apps for iPhone, iPad, or iPod touch running iOS 8. You can also test your apps using the included iOS Simulator, which supports iOS 8. iOS SDK 8.0 requires a Mac computer running OS X v10.9.3 (Mavericks) or later. This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.

Using MBS Plugin with Filemaker Ios SDK
Using MBS Plugin with FileMaker iOS SDK As some new people play with FileMaker's iOS SDK and our MBS Plugin, here a few steps to give you an easier start: • Get iOSAppSDKPackage_16.0.1.tbz on the iOS App SDK webpage from FileMaker's community benefits. • Unpack the archive. • Open Terminal, cd to the folder of the app sdk. For me this command line: • cd /Users/cs/Desktop/iOSAppSDKPackage_16.0.1 • Run the makeprojdir command giving a folder name, the app name and the identifier: • ./makeprojdir test test de.monkeybreadsoftware.test • Of course you use your own names and bundle id. • Open test project in Xcode • In the target popup menu you can select a simulated device and when you run the app. The section for installed plugins will be empty. Congratulations, now the app should run in simulator! If you have trouble till here, maybe you review the iOS App SDK 16 Guide. • Now you can drag & drop the plugin into the plugins section in the Xcode project right in the Custom Application Resources folder. • Run the app again and it should show the plugin listed with version. Now you can use the plugin in your scripts for the solution and test in the simulator. If the plugin is not visible, please check logs and see if some error occurred. Please use MBS("Trace") command to write all plugin calls to the log in Xcode, so you spot errors easier. • Next you can change target to be your iPhone and run the app on the iPhone. This may need some code signing things and an Apple ID registered for developing.
