   • What is the purpose of the `name` attribute in a checkbox input element?

     Top Answer

     Answered Sep 02, 2010 · 35 votes

     Dont be confused because of name="checkbox". It could more logically be name="drink" and type=checkbox.

     In the above case, you have multiple checkboxes with the same name. When several checkboxes have the same name, the form will send a group of values to the server in the request. Note: only the values of the checked checkboxes will be sent to the server.

     Ideally these are used to allow multiple choice questions where more than one answer is allowed. As opposed to radio buttons, where only one answer is allowed among the options.

     Update:

     On the receiving side, if you're using JSP for example - the values of the selected checkboxes will be available as request.getParameterValues("drink") or request.getParameterValues("checkbox") in your actual case. This is where the name attribute is used.

     Take a look into MSDN. For example Workbook is

     [GuidAttribute("000208DA-0000-0000-C000-000000000046")]public interface Workbook : _Workbook, WorkbookEvents_Event -

     So Workbook extends _Workbook with methods from WorkbookEvents_Event, which means that many event handlers are added - that's all.

     The rest interfaces are similar.

   • What is the role of name="..." attribute in input?

     The name ("control name") will be passed into the query string when the form is submitted. This is different from the id

     attribute which is used to identify an element uniquely by the UA (browser).

     With name, the query will be like

     /index.php?s=&submit=Go!-

     Without name, the query will be like

     /index.php-

   • What is the name of the cascading view of all apps in android home (see attached pic)?

     Top Answer

     Answered Dec 19, 2016 · 1 votes

     That is called the Overview Screen (aka recents screen, recent task list, or recent apps) - https://developer.android.com/guide/components/recents.html

     When you swipe an app to the side and remove it from the list, it kills any background or empty processes the application is currently running, and then possibly kill the services that are running depending on if you set the onTaskRemoved() callback ( more info here: https://developer.android.com/reference/android/app/Service.html#onTaskRemoved(android.content.Intent) ). By default it does not remove any running services, though.

     Things like Alarms, PendingIntents and Notifications will not be removed just by sliding the app closed in the overview screen. That only happens if a user does a force stop on the application (in the phones main Application Settings).

     If the app was previously put into the background from pushing the home button or opening another app, then its state would be a background process and the last activity states in its lifecycle would be onPause() followed by onStop(), then when you swipe it to the side onDestroy() is called.

   • What is the name of the design pattern for marshalling in libraries like Akka Http or http4s?

     It's done using type class (for serialization logic) and implicit class (to extend method syntax).

     Create type class - it's a generic trait:

     trait XmlSerializer[T] { //type class type Xml = String def asXml(element: T, name: String): Xml}

     Create companion object:

     object XmlSerializer { //easy access to instance by XmlSerializer[User] def apply[T](implicit serializer: XmlSerializer[T]): XmlSerializer[T] = serializer //implicit class for myUser.asXml("myName") syntax //serializer will be injected in compile time implicit class RichXmlSerializer[T](val element: T) extends AnyVal { def asXml(name: String)(implicit serializer: XmlSerializer[T]) = serializer.asXml(element, name) } //type class instance implicit val stringXmlSerializer: XmlSerializer[String] = new XmlSerializer[String] { override def asXml(element: String, name: String) = s"<$name>$element</$name>" }}

     Create type classes instances for your model:

     case class User(id: Int, name: String)-object User { implicit val xmlSerializer: XmlSerializer[User] = new XmlSerializer[User] { override def asXml(element: User, name: String) = s"<$name><id>${element.id}</id><name>${element.name}</name></$name>" }}case class Comment(user: User, content: String)object Comment { implicit val xmlSerializer: XmlSerializer[Comment] = new XmlSerializer[Comment] { import example.XmlSerializer._ //import fot implicit class syntax override def asXml(element: Comment, name: String) = { //user serializer is taken from User companion object val userXml = element.user.asXml("user") val contentXml = element.content.asXml("content") s"<$name>$userXml$contentXml</$name>" } }}

     Use it: object MyApp extends App {

     import example.XmlSerializer._ //import fot implicit class syntax- val user = User(1, "John") val comment = Comment(user, "Hello!") println(XmlSerializer[User].asXml(user, "user")) println(comment.asXml("comment"))}

     Output:

     <user><id>1</id><name>John</name></user><comment><user><id>1</id><name>John</name></user><content>Hello!</content></comment>-

     Logic is implemented poorly, but it's not the point.

   How do I refer to input files in options?

   • To refer to input files in options, you must use their indices (0-based). E.g. the first input file is 0, the second is 1, etc. Similarly, streams within a file are referred to by their indices. E.g. 2:3 refers to the fourth stream in the third input file. Also see the Stream specifiers chapter.

   How do I encode a stream?

   • Select an encoder (when used before an output file) or a decoder (when used before an input file) for one or more streams. codec is the name of a decoder/encoder or a special value copy (output only) to indicate that the stream is not to be re-encoded. For example encodes all video streams with libx264 and copies all audio streams.

Note that if you use something like char *buffer = malloc(BUFFER_SIZE); (if (buffer == NULL) { …error… } buffer = fgets(buffer, BUFFER_SIZE, fp); and the file stream is empty, you've just written over the only pointer to the allocated memory and have created a memory leak.
