On the Genealogy of Morals …
book tv essay DISADVANTAGES OF TELEVISION. Of Morals Essay 1 Summary? In today modern world television is the swap resume, most popular and recognized from of media and most homes in the western and developed worlds own one. That small (in some cases rather large) box sitting in your lounge is your connection to the outside world. It is an indispensable item and of morals essay, many of us cannot imagine life without it. Grub Swap? As with everything there are advantages and disadvantages with the television. The main advantage is televisions ability to bring you news as it happens. A second advantage is the fact we are using more than one sense when viewing. The final advantage in this essay is the vast amount of information and documentaries available for essay, viewing. Swap Resume? However the 1 summary, first disadvantage is the amount of time spent watching television is about tv addiction, often considered a waste of time. Of Morals Essay 1 Summary? The second disadvantage is the fact that families may be in the same room but with the television on may not even acknowledge each other.
The final disadvantage illustrated in essays, this essay is that young children are often being exposed to 1 summary sex scenes and scenes of essays, violence. Firstly, for many of us the television is our first or only source of news and current events. Most channels have news updates up to four times a day and current affairs programmes which take a deeper look at the news that has affected the world that day or week. Theses programmes are often family friendly and are sometimes the only form of media available or easy to essay 1 summary understand for high multi-genre papers, children or non-speakers of English. These news shows keep people up to date on the outside world it is of morals essay, possible to know everything that happened in a day without even going outside. However these news shows can try and monopolize people's opinions and for furniture, be a bias to one political party or one side of a war. Secondly, what many of us do not realise is that we use at least two senses to enjoy television.
We use our eyes to genealogy of morals watch the television screen and the visual on the screen. Essay? We also use our ears or hearing to genealogy of morals essay listen to the dialogue and introduction dissertation, noises on the screen. Compared to other forms of media which usually involve only one sense e.g. the essay 1 summary, radio only requires the hearing sense and a book only requires sight. Even though the television lets us see and hear things it can cause eyesight problems and many people turn there televisions up which can cause hearing problems. The final advantage is the vast amount of educational programming available for viewing particularly on channels like the discovery channel and national geographic which can educate and plauger on purpose, stimulate people and wet every audience member's appetite. Of Morals? It is also the fastest way to improve your knowledge and help you learn something completely new. Where else can you learn about Marylyn Monroe and swap, Winston Churchill in the same afternoon?
Many people who cannot afford university or night courses or simply just want a basic knowledge of one particular subject or event. Use documentaries to quench their thirst for learning. The first disadvantage is essay 1 summary, that many people do not realise how much time they spend watching television if you spend one hour a day watching television. That is 365 hours a year and 3607 hours in ten years. You can only resume imagine what you could do with that time, it is possible to learn a language or do a university course. Many value their television shows over exercise or physical activity which can lead to obesity and 'couch potato'. Many people also feel the desire to essay 1 summary watch a favourite television show every day or every week and neglect social commitments and therefore becoming anti-social. A second disadvantage is that many people neglect their families so they can watch television. A family may be in the same room but would not say a word to each other or acknowledge each other.
Many families now also eat dinner in front of the resume for furniture, television which means normal dinner table conversation is lost. Most large families also have multiple televisions so that each member can watch the programme they would like to watch this means that some families may spend less than an hour in each others company before going to bed. A final disadvantage of watching television is the violence and sex scenes that young children are often exposed too. Many of us find shows with crime or violence entertaining but these are not suitable for children of young ages. These scenes are practically common on crime dramas. Children may not intentionally be being exposed but by simply being in or near the same room as an of morals 1 summary, older child or adult watching the programme. Introduction? With children being exposed to these scenes it can corrupt there innocent minds leading them in some extreme cases become violent to other children.
It can also lead to of morals essay more permanent problems such as violence or evil thoughts well into adulthood. Fortunately this can be easily avoided or reversed by not allowing young children to view these programmes by placing them in p. j. programming on purpose design, a different room from the television or sending them to genealogy of morals essay 1 summary bed. In conclusion television is dissertation, perhaps the world's greatest invention though it is genealogy, possible it will one day be replaced by something resembling a computer it is still indispensable in todays modern world. Television however has advantages and disadvantages as illustrated in this essay. It can be an educational, multi-sensory communication devise that takes up our time to exercise or our family time it can also have scenes that corrupt young minds. As Winston Churchill once said 'the best things are either immoral or bad for you' television is best in moderation.
So next time you're bored don't turn on the television go out and play some sport.

The Vital Guide to iOS Interviewing. The population of iOS developers has grown significantly in the years since the iPhone was released for 3rd party development in 2008. There are now well over a million iOS apps available for download on the App Store, supplied by an ever-expanding global community of developers. For those looking to hire an iOS developer, this newfound popularity is both a blessing and a curse. While it makes locating iOS developers easier than ever, it also makes it that much more difficult to sort through the high multi-genre research, many available candidates to locate those who are really iOS experts. Part of the challenge lies in genealogy of morals essay 1 summary, the fact that true expertise extends far beyond coding knowledge. It entails being aware of the various options that exist to implement a solution, as well as the tradeoffs that come with these different choices in terms of productivity, scalability, performance, and maintainability. With that in mind, this article offers a sampling of grub swap, questions that can be used to evaluate the depth and breadth of a candidate’s overall iOS expertise. With regard to essay coding, this hiring guide attempts to high papers be as language agnostic as possible, while still addressing the majority of the iOS developer community (i.e., those who write iOS apps in Objective-C or those who are in various stages of genealogy of morals, adopting Swift). Yet it is important to recognize that iOS apps can also be written in Ruby, Python, C#/.NET, Lua, Pascal, and even using abstraction libraries that let you write iOS apps with web technologies.
That said, since the frameworks for iOS development are by and large written in Objective-C, a basic knowledge of high school papers, some Objective-C concepts are required to do iOS development and are therefore discussed in of morals, this guide. One note of essays about tv addiction, caution: These sample questions are intended merely as a guide. Not every “A” candidate worth hiring will be able to properly answer them all, nor does answering them all guarantee an of morals essay 1 summary “A” candidate. Rather, these questions are meant to serve as a valuable component of an overall effective recruiting process, as described in our post In Search of the Elite Few. At the grub resume, end of the of morals 1 summary, day, hiring remains as much of an art as it does a science. There are some fundamentals of iOS programming (Objective-C in particular) that a candidate should be familiar with. Here are some examples. Q: Describe the use of methods and messages in Objective-C. Discuss some of the advantages and introduction, disadvantages of this approach. A method in Objective-C is associated with a class. Objective-C has instance methods requiring (in object-oriented parlance) an instance of a class, and class methods which can be called with just a class (similar to the notion of static methods in genealogy essay, Java, for example).
Methods are invoked by on purpose on software, sending them a message. Here’s an example of sending a message to a myUser object: In Objective-C, unlike many other languages (including Swift!), we can send messages to genealogy null objects with no negative side effects (the message is ignored and execution simply continues). In earlier versions of the Cocoa toolchain you could also call a method that the compiler, at compile time, couldn’t determine the resume, existence of. While this may sound like a powerful capability, it was more commonly a source of hair-pulling debugging scenarios. It’s important to note here that in addition to of morals essay the “strange” square braces to send a message, to the uninformed eye, Objective-C appears to have a concept of external parameter names (a term borrowed from Swift), but this is not the case. P. J. Essays On Software Design. In the of morals essay 1 summary, above example, the method being called must have forDuration: plus an grub swap accompanying parameter, and it must be in that same position in genealogy essay 1 summary, the method call. (For more information about how parameter names work in Objective-C, see this blog entry by Bill Bumgarner, written in response to this post on on software design PyObjC by Toptal’s Ryan Wilcox.) Q: What is a selector and essay, what is grub resume, its purpose? Provide an genealogy 1 summary example of essays about tv addiction, where and how it might be used.
A selector is the mechanism used to select a method to genealogy essay 1 summary execute for an object, or the unique identifier that replaces the name when the source code is for furniture, compiled. A selector acts like a dynamic function pointer that points to the implementation of a class’ method. As an example, suppose you had a selector for the method run , and three classes ( Dog , Athlete , and ComputerSimulation ) that each implemented a method run . The selector could be used with an of morals essay instance of each of the classes to invoke its run method, even though the implementation might be very different for each. Q: How can you check dynamically at runtime to high multi-genre see if a class supports a method that can respond to a particular message? The respondsToSelector: method returns a Boolean value that indicates whether the receiver implements or inherits a method that can respond to a specified message. The ability to check dynamically at runtime if a class supports a method can be particularly useful with delegates (see the next question in this guide) that can have optional methods a developer can choose to implement or not. A common pattern is to use respondsToSelector: to see if a delegate object implements an optional method before sending it that message. For example: As noted in Apple’s iOS documentation, though, you cannot test whether an object inherits a method (from its superclass) by sending respondsToSelector: to the object using the essay, super keyword. Sending respondsToSelector: to super is equivalent to sending it to resume self . Instead, you should use the instancesRespondToSelector: method on the object’s superclass, for example:
Q: What is the genealogy 1 summary, delegate pattern and essay, what is it used for? Describe the delegates used by a UITableView . Delegation is where one object relies on another object to supply some well-defined functionality, state information, data, or events. As stated in of morals essay 1 summary, Apple’s Cocoa Developer’s Guide, “the main value of delegation is that it allows you to easily customize the behavior of several objects in legal studies, one central object”. A great example of delegation is the UITableView object that is typically used when a table is rendered on the screen. The UITableView employs two different delegates: UITableViewDelegate : Invoked if the genealogy of morals, user has, for example, selected a cell, or to determine what the height of a row should be.
UITableDataSource : Used to retrieve information relating to introduction dissertation how each cell in the table should be rendered, how many rows there are, if rows can be edited or moved, and so on. Q: What are categories in Objective-C and how do they differ from subclasses? A category is a way to extend an existing class and is an alternative to of morals the use of subclasses. The main distinction between subclassing and categories is that a category adds functionality to introduction an existing class itself which is then available anywhere in your code that uses that class or its subclasses. Essay. In contrast, subclassing creates a new class with added (or altered) functionality. You must then use that new subclass, rather than the original class or any of its subclasses, to access this extended or revised functionality. For example, the common string object in Objective-C is NSString and it has a mutable subclass NSMutableString. For Furniture. When you use a category to extend the genealogy of morals 1 summary, NSString class, every NSString and NSMutableString object in introduction dissertation bac francais, your code will support these new methods. These new methods can then be invoked on any NSString or NSMutableString in any class that imports the 1 summary, category header file.
A potential pitfall with categories, though, is name clashes. If you implement a category method with the same name as an existing method in introduction, the referenced class, the behavior at runtime is undefined (i.e., it is unpredictable which of the versions of the of morals essay, method will be invoked). To avoid name collisions, Apple recommends using a three-letter prefix before any category methods. Another limitation of a category is that it cannot define new instance variables for a class. However, an experienced developer will be aware that you can define new state objects associated with the class using Objective-C runtime methods, which provides a way for a category to store state changes. Q: Describe error handling in Cocoa. Most errors are handled in Cocoa via NSError . Two of the plauger p. j. programming design, more common approaches are as follows: Pass a blank NSError object into a method and, when the genealogy essay 1 summary, method completes, check to see if that object is school multi-genre, still blank or contains an error. (To be entirely precise, pass in a pointer to the NSError pointer, or NSError ** in Objective-C parlance.)
Pass an NSError object to some failure delegate method or callback. NSError objects have an error domain, an error code, and user info dictionary for additional information. This additional information might include, for genealogy essay example, a localized description and essays about, recovery suggestion, so later code can display that to the user. In addition to NSError , iOS development also has NSException . Unlike exceptions in other languages, NSException is intended to be used for programming errors only. Cocoa frameworks in general are not exception-safe, so if you generate (or invoke code that generates) exceptions, care should be taken to use try/catch as close as possible to of morals essay the place where the exception is occurring. Swap Resume. In practice, NSException is rarely used in iOS codebases. Q: What are some common causes of exc_bad_access errors and of morals 1 summary, how might you go about debugging them?
exc_bad_access errors are a common occurrence that can frustrate beginner iOS developers due to the lack of useful debugging information that they provide. They often occur when trying to access an object that was never initialized or has already been released. These errors can also result from passing a parameter to a message that the resume for furniture, message is not intended to of morals receive (e.g., passing in an NSInteger when an NSString is expected). Note that, in certain cases the compiler will provide a warning that, if heeded, can alert the developer to essays about tv addiction the problem so it can be resolved before any runtime error occurs. But if such warnings ignored, exc_bad_access errors may occur. Here, for example, is erroneous code that is attempting to format a string using an integer variable: The %@ in the string format specification indicates that an object, rather than an of morals essay 1 summary integer, is expected (an integer would be represented with %d ). This statement will therefore result in essays tv addiction, a compiler warning and, if ignored, will result in an exc_bad_access error at genealogy of morals essay 1 summary, runtime. But not all causes of legal essay, exc_bad_access errors will be identifiable by the compiler. A common cause of exc_bad_access errors that are not detectable by the compiler is attempting to access released objects.
In such cases, enabling NSZombies in genealogy essay, Xcode can be an effective debugging technique. Enabling NSZombies keeps objects that would normally be released alive as “zombies”. After enabling NSZombies , you can then follow what is happening in high school multi-genre, your code and receive a message when the of morals essay, application tries to access an object that has been released, thereby identifying the problem in your code. For Furniture. A note of caution though: Be sure to remember to disable NSZombies before submitting the of morals, app to the App Store. Plauger P. J. Essays Design. When NSZombies is 1 summary, enabled, no objects are released and you will be leaking memory constantly until your app eventually is killed due to dissertation bac francais memory warnings. As mentioned, true iOS expertise extends far beyond coding knowledge. Highly experienced iOS developers will have a thorough understanding of what’s going on “under the hood” on the iOS platform. They will also be well aware of the various implementation options available, including the tradeoffs that come with these different choices in terms of productivity, scalability, performance, and maintainability. The questions that follow help assess this dimension of a candidate’s expertise.
Q: Compare and contrast the MRR and ARC approaches to memory management in genealogy 1 summary, Objective-C. Objective-C keeps track of what objects are in use, or not, by use of a retain count . When an object is in use by another object it’s retain count goes up; when it is not being used by any objects, its retain count reverts to zero. In Objective-C there are two ways to manage this retain count: With MRR , developers had to worry about bac francais autoreleasing an of morals 1 summary object, or putting it in an auto release pool in certain situations. In contrast, ARC automatically takes care of resume, many of these concerns. Most iOS applications and genealogy essay 1 summary, developers have therefore switched over to ARC. In fact, with Swift, ARC is required. While ARC does require some thought (around object ownership for example) the requirements on developers are much less with MRR.
Q: How can you improve performance when drawing and animating a view with shadows? If you need to apply a shadow to a view, many inexperienced developers will import the QuartzCore framework and apply a shadow to the layer property of the view; e.g.: While this is about tv addiction, a simple way to genealogy of morals 1 summary add a slightly transparent shadow on essays about tv addiction a view, it can result in poor rendering performance. Unfortunately, the rendering engine usually needs to check each pixel of the essay 1 summary, view to determine the school multi-genre, shadow’s outline. However, you can define a shadow path to avoid this expensive calculation and optimize the rendering. For a standard rectangular view, you would define a shadow path as: This provides much better performance, though you must keep in mind that whenever the view’s bounds change, the shadow path also needs to be updated. By default, when animating a view with a shadow, the shadow is redrawn during each stage of the animation.
You can optimize animations with shadows by rasterizing the layer of the view with the shadow. When the layer with the shadow is 1 summary, rasterized, it is rendered as a bitmap in its local coordinate space and grub swap resume, then composited to the destination. Here’s an example of how you could rasterize your shadow effects: Q: What are some common causes for poor performance in scrolling table views? How can they be avoided? When the 1 summary, iPhone originally came out, smooth scrolling was one of the keys to the positive user experience. However, there are many mistakes a novice developer can make that can cause a lag to occur while scrolling. School Papers. Examples include: Not using a reuse identifier properly. Genealogy 1 Summary. The default behavior when a table is scrolled is that table cells that go offscreen are deallocated and new cells are created for the new content that is shown.
When you use a reuse identifier, when a cell goes off screen it is not deallocated and for furniture, instead cached for reuse. If a new cell is to of morals 1 summary appear with the introduction, same reuse identifier, the genealogy of morals essay 1 summary, cached cell is used and introduction dissertation bac francais, the expensive operation of allocating and laying out an entirely new cell is genealogy of morals 1 summary, avoided. Instead the cached cell must only be reconfigured to display the new content, such as updating the text and image that is displayed. Synchronously loading web content. If loading is done synchronously, it will stall out the main thread while the plauger programming on software design, data loads, which can cause a perceptible lag when scrolling. This is essay 1 summary, a particularly common problem when images are being downloaded for plauger on purpose design displaying in table cells. The solution here is to use a placeholder value or image and load the essay, data asynchronously in the background. Resume For Furniture. Once the data is loaded, a message can then be sent to the main thread to update the appropriate cells. Applying expensive operations when setting up a cell for display. Expensive operations, such as converting a high-resolution image to a thumbnail or applying a complicated photo filter or transform to an image, can severely degrade display performance.
If you only need a thumbnail size image, store a smaller size locally. Similarly, apply any complex transforms to genealogy the image in advance if possible. Alternatively, perform the necessary operations on the image off the main thread and then refresh the cell once the image is ready for display. Overly complex view hierarchies. While you can use the various UIViews to create custom cells, this has the potential to degrade performance if it is overused or gets overly complex.
Although this has become less of an issue with the increasing speed of supported iOS devices, it still can impact scrolling performance in some devices and scenarios. Legal Studies Essay. Although tedious, this problem can be addressed by implementing your own drawing of the cell’s content (i.e., replace the UILabels, UIImages, etc., with a UIView and then implement your own drawing in that view). If done properly this can significantly improve performance when rendering cells. Q: Diagram out the Core Data stack. Core Data is Apple’s model layer, persistent object store, and object graph manager. Essay 1 Summary. You might be tempted to plauger programming on purpose essays on software design call Core Data Apple’s Object Relational Mapper, but it’s really more than that.
Below is of morals, a diagram of the Core Data stack. Note: It’s extremely rare to find a developer who can map out the entire Core Data stack from memory. The more important / frequently used parts of resume, Core Data are those that are within the orange highlighted portion of the diagram below. Q: Is Core Data thread safe? How can you deal with this in your app? Core Data is not thread safe. The approach therefore recommended by Apple is to use thread containment which entails creating a separately-managed object context for accessing Core Data objects on each thread and having a single shared persistent store coordinator. Essay. If you need greater concurrency, you can also have separate persistent store coordinators, though this comes with added complexity and also increased memory usage. Before iOS 5, the developer needed to manually manage the threads. However, the release of iOS 5 added new methods to the managed object context to eliminate the studies essay, need for genealogy essay manual thread management; instead you can safely access Core Data objects through a block of code passed to the performBlock: or performBlockAndWait: methods. Keep in mind, though, that changes to about tv addiction Core Data objects do not necessarily propagate immediately to other threads.
In the standard case, Core Data objects that are loaded into memory are not updated on genealogy essay a different thread until those objects are fetched again from persistent storage. In order for a managed object context to introduction dissertation take in changes from of morals essay 1 summary, Core Data objects on another thread immediately, it needs to be observing the NSManagedObjectContextDidSaveNotification . Once this notification occurs, the object can merge the grub swap, changes using the 1 summary, mergeChangesFromContextDidSaveNotification: method. Q: Describe different ways to achieve concurrency on the iOS platform. The following mechanisms are provided on the iOS platform for achieving concurrency: NSThread . Cocoa provides support for creating threads and executing code by subclassing NSThread . NSOperationQueue . Introduction. NSOperationQueue is a simple API that determines how many things can run simultaneously, then goes and does them. It allows you limit the number of operations running concurrently (e.g., to limit the genealogy of morals essay 1 summary, number of concurrent downloads). While simple and useful, it’s a layer of introduction dissertation bac francais, abstraction beyond manually managing NSThread and genealogy 1 summary, the complications that can involve. (It’s often sadly unused.) Grand Central Dispatch (GCD) . GCD is Apple’s approach to resume providing access to low-level concurrency. There’s a lot in GCD, but sometimes you really want a low level tool.
GCD includes some useful tools, particularly the following: dispatch_async : When given a task (the code in a block) it will run it at some point in the future. Genealogy Of Morals Essay 1 Summary. dispatch_group_async : You can create a group of dispatched tasks using dispatch_group_create() and dispatch_group_async() . You can even wait for all the resume for furniture, tasks in the queue to complete with dispatch_group_wait() . Swift is a new programming language from Apple that is referred to 1 summary as “Objective-C without the grub, C”. Swift can work side-by-side with Objective-C, offering many improvements that enable developers to create apps that are more stable and have better performance in less time. Overall, it is the single biggest change to iOS development since the initial release of the iOS SDK. 1 Summary. Unveiled at Apple’s WWDC in 2014, and legal studies, usable in production with the release of iOS 8 in September 2014, Swift will also be compatible with iOS 7 and OS X Mavericks. The Apple frameworks are used in the same manner in Swift, so an experienced iOS developer is able to transfer most of his or her knowledge to writing Swift code.
That said, there are several issues an of morals essay 1 summary experienced iOS developer should be aware of regarding Swift and its interoperability with Objective-C. Q: In what ways can Swift and Objective-C code be used together in the same project? What are some limitations in this regard? Provide an example. Both languages can be used in introduction dissertation bac francais, the same project, thanks to genealogy of morals essay bridging header files that Xcode automatically creates between the two languages. An example of this can be seen in initializing a plain table view. In Objective-C syntax, this would be specified as: In contrast, the Swift bridge removes the initWith syntax and modifies the on purpose on software design, formatting automatically to the Swift syntax as follows:
Fortunately, Swift is able to take advantage of anything written in Objective-C, so you can create a new Swift project and still utilize any existing code base. However, this bridging only works perfectly in genealogy of morals 1 summary, Objective-C to Swift (and not vice versa), so code that takes advantage of new features in for furniture, Swift will not be accessible in an Objective-C file. Examples of this include generics, tuples, and structures defined in essay 1 summary, Swift, for about which there are no Objective-C equivalents. Unfortunately, this can make it difficult or impossible to utilize some of the exciting third-party libraries that are being built in Swift with an genealogy of morals 1 summary existing Objective-C code base. Apple provides detailed documentation on studies essay how to utilize Swift with Objective-C, which every experienced developer should become familiar with.
Q: Compare method calling and messages in Objective-C and Swift. 1 Summary. Provide an example. While Objective-C uses the unique bracket syntax to call methods on an object, Swift uses the plauger p. j. programming essays, more conventional dot notation. So, a message like [myUser allowAuthorizationTo: secretChamber forDuration: oneHour] in genealogy essay 1 summary, Objective-C turns into swap resume, myUser.allowAuthorizationTo(secretChamber, forDuration: oneHour) in Swift. Q: Compare error handling in Objective-C and Swift.
Writing Swift code that interacts with Objective-C means dealing with NSError in the same way Objective-C does. In Swift, however, exceptions are no longer supported. Using a method that takes an NSError means using an optional variable (a variable that may or may not exist) and the unwrapping the error if it exists. As Swift is genealogy 1 summary, a new programming language, best practices around error handling, especially Swift code calling other Swift code, haven’t really emerged yet as of this writing (September 2014). With the iOS app development scene getting shaken up by the release of an entirely new programming language (Swift), it has become more important than ever to find elite iOS developers who have mastery of the platform and can transition between these two languages. While finding these experts is always a challenge and no brief guide can cover the topic entirely, we hope that the about tv addiction, questions in this post can provide a starting point for identifying developers with a solid mastery of the iOS development environment.
My team is going to personally help you find the best candidate to join your team.
