The rest of a division is what remains, if a division is not accurate, for example, when you try to know if a number is pair in programming, it is used (num % 2) == 0 this code means, if the rest of 'num' divided between 2, is equal to 0, this means that it is pair, for example(10 % 2) == 0 this returns true, as the rest of 10 divides between 2 is 0, 3% refers to this case in 0

display:ruby is the standard display ta tag <ruby>. Just like the standard display <div> It is block and <span> It is inline.Chrome does not seem to use display:ruby for the tag <ruby>, but at FireFox vc you can already check it works. Despite this, the tag is not so new, and it appears in the W3C Working Draft since 2014 as vc can check on the official link Ruby annotation is an interline annotation form, consisting of small text strings next to the base text. They are usually used in Eastern Asian documents to indicate pronunciation or provide a short annotation.That is the tag ruby is used as text markup to indicate the pronunciation of some text in another language, usually Asian. Also, the tag should not be used alone, it should be used in conjunction with the tags <rp> and <rt> to assist in the construction of the marking. An element <rp> must include each of the opening and closing brackets involving the element <rt>which contains the text of the annotation. O <rp> is optional and helps to format the text when the browser does not support the ruby.Along with the ruby vc tag you can also use other CSS property as ruby-align and ruby-position to control how you want to visually show the text annotation. Here is more technical details See the example<ruby> 漢 <rp>(</rp><rt>Kan</rt><rp>)</rp> 字 <rp>(</rp><rt>ji</rt><rp>)</rp> </ruby>Another example, more complex a little and with two notes. <ruby> <ruby>東<rt>とう</rt>南<rt>なん</rt></ruby> <rt lang=en>Southeast</rt> </ruby>Source:

JNDI is API from the standard library. This API was https://web.archive.org/web/20040908114732/http://www.sun.com/smi/Press/sunflash/1997-03/sunflash.970310.10204.html 5 years before the first version of spring in 2002. Not all projects use spring, and a standard way to register and find resources is needed. JNDI is an opportunity.

Version 6.2 does not contain the datePicker component.Your options are updated to 6.2.14 or 7.The change to 6.2.14 should be the least costly in terms of migration/differences with your current version, but requires PrimeFaces license.The 7 is free access, but could involve more changes to update.

In the build configuration of the library,Module StabilityHomeABI Stability in Swift 5 is divided into two parts:ABI StabilityOthersModule StabilityHomeABI Stability is now available in Swift 5.0. This is a "linkable" binary generated from a different version of the compiler.This eliminates the need to include Standard Library for each app.Module Stability This is a "importable" module generated from a different version of the compiler.Swift makes frameworks and libraries available (= import) "module" is required.*.swiftmoduleThe file was responsible.To use another library object or function from source code, you need to "import" and call the function through public API.This public interface can be imported*.swiftmodule(=Module) (*.swiftmoduleFile is a header file in C or Objective-C. When importing C and Objective-C libraries to Swift as the same as the module, use the modulemap file which can convert the header file to the module, but it is omitted because it is not related to this issue. )More*.swiftmoduleThe file is not compatible with the version of the compiler generated. 。So Swift 5.1 can keep compatibility between compiler versions*.swiftinterfaceA text-based module description file called a file was adopted.Swift 5.0You can link the library generated by a different version of the compiler, but you can't get ABI Stability for virtually any third-party library because you can't importHome(In order not to reach the link stage because it fails at the import stage)Swift 5.1 Module Stability can be used without worrying about the version of the compiler built in any library.Module Stability*.swiftinterfacewill not be generated if each library side has enabled and built.*.swiftinterfaceto outputBUILD_LIBRARY_FOR_DISTRIBUTIONflagYESshould beMost libraries have not yet enabled, so if you build with Carthage*.swiftinterfaceNo files are generated.This is why the module in Swift 5.1 cannot be imported in Swift 5.1.2.(The Swift Standard Library was done without Embedded from around Swift 5.0 because Module Stability was enabled as a Private feature for Apple modules before we were able to use Module Stability)Reference: https://swift.org/blog/abi-stability-and-more/ https://forums.swift.org/t/plan-for-module-stability/14551

Not available The easiest way to use instance variables.before_action :hoge def hoge @val = "abc" end def huga puts @val end There is also a method that can be accessed by the method name by memoizing the processed contents.before_action :hoge def hoge @val ||= "abc" end def huga puts hoge end before_action"abc"is generated only once.

The problem is, for every client, MySQL makes DNS lookup, add the next line (skip-name-resolve) to mysqld and reboot the server.[mysqld] skip-name-resolve In order to determine the reasons for such problems, study and use the tcpdump team, she'll tell you what stage the problem of the compound was.

Careful.: The answer is written when MRI 2.3 was relevant. https://blog.heroku.com/ruby-2-4-features-hashes-integers-rounding#unified-integers ♪ But the particularities described still exist, just if it was easy to recognize people in class before, it's now a deep-blown piece of implementation.Because... Object#eql? and Object#equal?) x and xx not just equal but the same meaning, even references (in Ruby, I remind you, all meanings are references, with a couple of reservations, one of which I'm about to tell).In MRI, if you look object_id (who de facto detracts the meaning of the reference; the reference itself, not the meaning for You can see what the equals have. Fixnum♪ 10 represents one of them) the same object_id under any circumstances: Whether it's in the code, whether the calculation results. ♪ ♪Cash? I mean, MRI is clashing the chisel objects and getting them by weight?Almost. Not really.Crazy binary khaki"Translation Fixnum MRI contains its meaning insideright in the reference. If most of the facilities are in place object_id This is an indicator on the object in memory (or Object addressI mean, you know, Fixnum (and at some other classes) this "correlation," if you interpret it as an index leads... somewhere better not to watch. There might be something interesting, maybe someone else's memory. Because I have Fixnum'Cause that's it. Not Index.object_id Ooh. Fixnum It's the number one to the left and one to the younger bat. If you forget about the negative numbers at the time, object_id of FixnumAh, we need to multiply it by 2 and add 1.(0..100_000).all? { |i| i.object_id == (i * 2 + 1) } # => true With negative numbers, it's a little more complicated because the numbers are stored. https://ru.wikipedia.org/wiki/%D0%94%D0%BE%D0%BF%D0%BE%D0%BB%D0%BD%D0%B8%D1%82%D0%B5%D0%BB%D1%8C%D0%BD%D1%8B%D0%B9_%D0%BA%D0%BE%D0%B4_(%D0%BF%D1%80%D0%B5%D0%B4%D1%81%D1%82%D0%B0%D0%B2%D0%BB%D0%B5%D0%BD%D0%B8%D0%B5_%D1%87%D0%B8%D1%81%D0%BB%D0%B0) ♪ We've got to use the battery arithmetics.(-100_000..100_000).all? { |i| i.object_id == (i << 1 | 1) } # => true How does MRI know if the value of the indicator is in memory or Fixnum? It's very simple, in the younger bat, not really. Ruby does not use inaccurate indicators because all types have more than 2 bytes.A little more visible (and English) can be read about. http://www.sarahmei.com/blog/2009/04/21/object-ids-and-fixnums/ and you can even dig up Ruby's reference code. https://github.com/ruby/ruby/blob/8998c06461ea0bef11b3aeb30b6d2ab71c8762ba/include/ruby/ruby.h#L347 )But I'm here to speak exclusively of MRI. Are such behaviour guaranteed in all implementations? As Ruby has no specification as a language (not a translation) no, no.

Just for your information. Giving a direct database connection in a client side application is a bad idea. Build a RESTful interface which allows for correct authentication and input validation. This will allow you to have a stricter control on what your applications can access. The problem is that currently MongoDB doesn't offer SSL encapsulation. This means that in itself, the wire protocol can be eavesdropped upon (the data sent over the protocol is exposed). So if you are running this protocol non-locally (so across a network) then yes it's not secure, but not because the protocol itself is insecure, but because the implementation currently can't guarantee confidentiality or integrity due to the lack of encapsulation. However you can fix this by encapsulating the protocol yourself. If the protocol doesn't offer SSL you first make a tunnel and send the protocol through that tunnel. For instance you make an encrypted VPN between your webserver and MongoDB and through this VPN you send the wire protocol connection (note that you should use a secure VPN protocol). Preferably this is implemented so that you have end-point encryption. This will disallow eavesdroppers from sniffing your wire connection.

You have nothing wrong with the code, the pattern strategy is well implemented, the reason for switch-case It's because listener, he's in charge of creating the printers, i.e. the listener becomes a factor of concrete objects, which they implement strategy , The nature of the factor is to fork and determine object X to create, so it's normal to see switch-case Printer.java has two responsibilities, both responsibilities are in actionPermorfed if we assume a method called update to change, choose the printer to use (the value of default_printer) and update the document then the code is reduced in : public void actionPerformed(ActionEvent e){ System.out.println("su trabajo se está procesando..."); actualizarImpresora(); default_printer.print(); System.out.println("Trabajo terminado."); }} this is a partial solution, since actionPerformed I shouldn't update anything, that should do the same. comboBox through a ItemListenA Better Solution :First of all, you have to modify the Printer interface, to allow you to change the document in the march, after all, a printer prints several documents, if they were disposable, we would have to buy a printer per document (imagine costing it...) public interface Impresora { public void print(); public void setDocument(Object document); // permite cambiar el documento "on the fly" } Then to class Printer, it is created by default printers, which match the combobox index.Archive Printer.javaimport java.awt.event.*; import javax.swing.JComboBox; import javax.swing.JTextArea; public class Printer implements ActionListener{ //Para obtener el tipo de impresión correcta private JComboBox combobox; private JTextArea area; private Impresora default_printer; private Impresora[] impresoras; public Printer(Vista vayjay){ impresoras = new Impresora[]{ new ImprimeTXT(), new ImprimePDF(), new ImprimeCSV() }; combobox = vayjay.getComboBox(); combobox.addItemListener(new ItemListener{ @Override public void itemStateChanged(ItemEvent e){ default_printer = impresoras[combobox.getSelectedIndex()]; } }) area = vayjay.getTextArea(); default_printer = impresoras[0]; } public void actionPerformed(ActionEvent e){ System.out.println("su trabajo se está procesando..."); default_printer.setDocument(area.getText()) default_printer.print(); System.out.println("Trabajo terminado."); }} What the Printer.java file does now is that it adds a ItemListen Al comboBox which is the manager of changing the printer to use when the user selects an option. Now actionPerformed just update the document on the printer, and print, you don't need to do anything else.

Hey!I can't see the whole solution.1. To create an abstract class. Field: x, y position and detection (boolean). Exterior abstract method: public abstract Node appearance();2. Create two subclasses (corables and proms) (extends). Example: public class Ship extends АбстрактныйКласс{ private Rectangle appearance; public Ship (int x, int y) { super(x,y); appearance = new Rectangle(20,20,Color.GRAY); } @Override public void move(Game gamer) { gamer.setxPos(getxPos()); gamer.setyPos(getyPos()); }@Override public Node appearance() { return appearance; } @Override public void setDetected(boolean detected){ super.setDetected(detected); if(detected){ appearance.setFill(Color.BLACK); }else{ appearance.setFill(Color.GRAY); } } 3. Class of the game itself, get and set positions.4. Well, the main class extends Application @Override public void start(Stage primaryStage) { try { GridPane root = new GridPane();... with the method of handling the kerb position.When depicting the battlefield setDetected in a false way a gray one.5. Class of pressurizing the left button of mouse at certain coordinates that alters the appearance of the field found. Well, that's right. Something's been missing, describing the concept.If all this is Canvas Canvas pole = new Canvas(400, 400); root.setCenter(pole); pole.addEventHandler(MouseEvent.MOUSE_CLICKED, new Move(pole.getGraphicsContext2D())); public class Move implements EventHandler<MouseEvent> { GraphicsContext teg; double X; double Y; public Move(GraphicsContext t) { teg = t; } @Override public void handle(MouseEvent hendelsen) { double x = hendelsen.getX(); double y = hendelsen.getY(); Get the coordinates, look into the body and describe what to do, i.e. changing the appearance or drawing anything.

I think you want to create a https://pt.wikipedia.org/wiki/Inst%C3%A2ncia_(classe) and not one https://pt.wikipedia.org/wiki/Est%C3%A2ncia . https://pt.stackoverflow.com/q/269089/101 .You can access all public members of the object type at that time. You cannot access the members of a type that is part of that object, but that is not the type being used at that time. If the guy is the father, you can only access his members, you can't access the child type members.If you can ensure that the object is of the child type can make a cast, which is a type conversion (not necessarily changes something in the data, only tells the compiler that you want to use a more specialized type. Then it is allowed to access the members of the child type, and the father also because the child always has everything the father has.In general cast fail will generate an error or the result will be a null. There are cases that the compiler may identify that it is not possible and neither let it compile.In this example it does not make much sense to declare p1 as Pessoa if you know you need it as PessoaFisica, but it is possible, there you can write:((PessoaFisica)p1).cpf
