I had the same problem and i fixed by adding the component (MyComponentToUse) in exports array in the module where my component was declared (ModuleLower). Then i import ModuleLower in ModuleHigher, so i can reuse now my component ( MyComponentToUse) in the ModuleLower and the ModuleHigher

            @NgModule({
              declarations: [
                MyComponentToUse
              ],
              exports: [
                MyComponentToUse
              ]
            })
            export class ModuleLower {}


            @NgModule({
              imports: [
                ModuleLower
              ]
            })
            export class ModuleHigher {} 

2020 Update. To expand on both excellent answerd from @iamnewton and @Fernando Chavez Herrera I've started to see @ being used in the path of URLs.

So the updated regex is:

RegExp('(https?:\\/\\/)?((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.)+[a-z]{2,}|((\\d{1,3}\\.){3}\\d{1,3}))(\\:\\d+)?(\\/[-a-z\\d%_.~+@]*)*(\\?[;&a-z\\d%_.~+=-]*)?(\\#[-a-z\\d_]*)?$', 'i');

If you want to allow it in the query string and hash, use:

RegExp('(https?:\\/\\/)?((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.)+[a-z]{2,}|((\\d{1,3}\\.){3}\\d{1,3}))(\\:\\d+)?(\\/[-a-z\\d%_.~+@]*)*(\\?[;&a-z\\d%_.~+=-@]*)?(\\#[-a-z\\d_@]*)?$', 'i');

That being said, I'm not sure if there's a whitepaper rule disallowing @ in the query string or hash.

for one-liners:

print vars(theObject)

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

Use npm to uninstall. Just running sudo npm uninstall npm -g removes all the files. To get rid of the extraneous stuff like bash pathnames run this (from nicerobot's answer):

sudo rm -rf /usr/local/lib/node \ /usr/local/lib/node_modules \ /var/db/receipts/org.nodejs.*

There is a general problem: it's hard to mock time. Also, it's really bad practice to place long running/waiting code in a unit test.

So, for making a scheduling API testable, I used an interface with a real and a mock implementation like this:

public interface Clock {
    
    public long getCurrentMillis();
    
    public void sleep(long millis) throws InterruptedException;
    
}

public static class SystemClock implements Clock {

    @Override
    public long getCurrentMillis() {
        return System.currentTimeMillis();
    }

    @Override
    public void sleep(long millis) throws InterruptedException {
        Thread.sleep(millis);
    }
    
}

public static class MockClock implements Clock {

    private final AtomicLong currentTime = new AtomicLong(0);
    

    public MockClock() {
        this(System.currentTimeMillis());
    }
    
    public MockClock(long currentTime) {
        this.currentTime.set(currentTime);
    }
    

    @Override
    public long getCurrentMillis() {
        return currentTime.addAndGet(5);
    }

    @Override
    public void sleep(long millis) {
        currentTime.addAndGet(millis);
    }
    
}

With this, you could imitate time in your test:

@Test
public void testExpiration() {
    MockClock clock = new MockClock();
    SomeCacheObject sco = new SomeCacheObject();
    sco.putWithExpiration("foo", 1000);
    clock.sleep(2000) // wait for 2 seconds
    assertNull(sco.getIfNotExpired("foo"));
}

An advanced multi-threading mock for Clock is much more complex, of course, but you can make it with ThreadLocal references and a good time synchronization strategy, for example.

For the first non-paste() answer, we can look at stringr::str_c() (and then toString() below). It hasn't been around as long as this question, so I think it's useful to mention that it also exists.

Very simple to use, as you can see.

tmp <- cbind("GAD", "AB")
library(stringr)
str_c(tmp, collapse = ",")
# [1] "GAD,AB"

From its documentation file description, it fits this problem nicely.

To understand how str_c works, you need to imagine that you are building up a matrix of strings. Each input argument forms a column, and is expanded to the length of the longest argument, using the usual recyling rules. The sep string is inserted between each column. If collapse is NULL each row is collapsed into a single string. If non-NULL that string is inserted at the end of each row, and the entire matrix collapsed to a single string.

Added 4/13/2016: It's not exactly the same as your desired output (extra space), but no one has mentioned it either. toString() is basically a version of paste() with collapse = ", " hard-coded, so you can do

toString(tmp)
# [1] "GAD, AB"

The .pde file extension is the one used by the Processing, Wiring, and the Arduino IDE.

Processing is not C-based but rather Java-based and with a syntax derived from Java. It is a Java framework that can be used as a Java library. It includes a default IDE that uses .pde extension. Just wanted to rectify @kersny's answer.

Wiring is a microcontroller that uses the same IDE. Arduino uses a modified version, but also with .pde. The OpenProcessing page where you found it is a website to exhibit some Processing work.

If you know Java, it should be fairly easy to convert the Processing code to Java AWT.

Check if it is null or not e.g

if(Session["mykey"] != null)
{
  // Session is not expired
}
else
{
  //Session is expired
}

As the error clearly states, OffenceBox.Text() is not a function and therefore doesn't make sense.

add semi-colon the line before:

$total_pages = ceil($total_result / $per_page);

Look at JavaDoc of replaceAll method of String class:

Replaces each substring of this string that matches the given regular expression with the given replacement. An invocation of this method of the form str.replaceAll(regex, repl) yields exactly the same result as the expression

java.util.regex.Pattern.compile(regex).matcher(str).replaceAll(repl)

As you can see you can use Pattern and Matcher to do that.

I know this is an older post, but I think a good example of what Jiew Meng was trying to do can already be found on this site. Check out the side menu located here: https://stackoverflow.com/faq#questions. Looking at it without getting into it too deep, I can tell javascript attaches a fixed position once the scrolling hits below the anchor tag and removes the fixed positioning if the scrolling goes above that same anchor tag. Hopefully, that will get someone started in the right direction.

It can be done by two ways:

1. Using $routeParams

Best and recommended solution is to use $routeParams into your controller. It Requires the ngRoute module to be installed.

   function MyController($scope, $routeParams) {
      // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
      // Route: /Chapter/:chapterId/Section/:sectionId
      // $routeParams ==> {chapterId:'1', sectionId:'2', search:'moby'}
      var search = $routeParams.search;
  }

2. Using $location.search().

There is a caveat here. It will work only with HTML5 mode. By default, it does not work for the URL which does not have hash(#) in it http://localhost/test?param1=abc&param2=def

You can make it work by adding #/ in the URL. http://localhost/test#/?param1=abc&param2=def

$location.search() to return an object like:

{
  param1: 'abc',
  param2: 'def'
}

Type history in your terminal. It's not technically git, but I think it is what you want.

You can't see this method in javadoc because it's added by the compiler.

Documented in three places :

• Enum Types, from The Java Tutorials

The compiler automatically adds some special methods when it creates an enum. For example, they have a static values method that returns an array containing all of the values of the enum in the order they are declared. This method is commonly used in combination with the for-each construct to iterate over the values of an enum type.

• Enum.valueOf class
  (The special implicit values method is mentioned in description of valueOf method)

All the constants of an enum type can be obtained by calling the implicit public static T[] values() method of that type.

• Enum Types, Section 8.9, Java Language Specification

The values function simply list all values of the enumeration.

Short answer: final helps a tiny bit but... use defensive programming on the client side instead.

Indeed, the problem with final is that it only enforces the reference is unchanged, gleefully allowing the referenced object members to be mutated, unbeknownst to the caller. Hence the best practice in this regard is defensive programming on the caller side, creating deeply immutable instances or deep copies of objects that are in danger of being mugged by unscrupulous APIs.

In PHP I like using mysqli_real_escape_string() which escapes special characters in a string for use in an SQL statement.

see https://www.php.net/manual/en/mysqli.real-escape-string.php

The execution process is really confusing with recursive CTE, I found the best answer at https://technet.microsoft.com/en-us/library/ms186243(v=sql.105).aspx and the abstract of the CTE execution process is as below.

The semantics of the recursive execution is as follows:

1. Split the CTE expression into anchor and recursive members.
2. Run the anchor member(s) creating the first invocation or base result set (T0).
3. Run the recursive member(s) with Ti as an input and Ti+1 as an output.
4. Repeat step 3 until an empty set is returned.
5. Return the result set. This is a UNION ALL of T0 to Tn.

TLDR; MySql does not have an equivalent concept of varchar(max), this is a MS SQL Server feature.

What is VARCHAR(max)?

varchar(max) is a feature of Microsoft SQL Server.

The amount of data that a column could store in Microsoft SQL server versions prior to version 2005 was limited to 8KB. In order to store more than 8KB you would have to use TEXT, NTEXT, or BLOB columns types, these column types stored their data as a collection of 8K pages separate from the table data pages; they supported storing up to 2GB per row.

The big caveat to these column types was that they usually required special functions and statements to access and modify the data (e.g. READTEXT, WRITETEXT, and UPDATETEXT)

In SQL Server 2005, varchar(max) was introduced to unify the data and queries used to retrieve and modify data in large columns. The data for varchar(max) columns is stored inline with the table data pages.

As the data in the MAX column fills an 8KB data page an overflow page is allocated and the previous page points to it forming a linked list. Unlike TEXT, NTEXT, and BLOB the varchar(max) column type supports all the same query semantics as other column types.

So varchar(MAX) really means varchar(AS_MUCH_AS_I_WANT_TO_STUFF_IN_HERE_JUST_KEEP_GROWING) and not varchar(MAX_SIZE_OF_A_COLUMN).

MySql does not have an equivalent idiom.

In order to get the same amount of storage as a varchar(max) in MySql you would still need to resort to a BLOB column type. This article discusses a very effective method of storing large amounts of data in MySql efficiently.

There are several places on Windows where SVN will place cached credentials depending on system configuration. Read SVNBook | Client Credentials.

• The main credential store is located in %APPDATA%\Subversion\auth and you can run svn auth command to view and manage its contents.

• You can also run cmdkey to view the credentials stored in Windows Credential Manager.

• If your SVN server is integrated with Active Directory and supports Integrated Windows Authentication such as VisualSVN Server, your Windows logon credentials are used for authentication, but they are not cached. You can run whoami to find out your user account name.

First of all, have only one id="test"

Secondly, try this:

if ($('[name="test"]').is(':checked'))

Another solution, you can do it using ResourceLoader like this:

import org.springframework.core.io.Resource;
import org.apache.commons.io.FileUtils;

@Autowire
private ResourceLoader resourceLoader;

...

Resource resource = resourceLoader.getResource("classpath:/path/to/you/dir");
File file = resource.getFile();
Iterator<File> fi = FileUtils.iterateFiles(file, null, true);
while(fi.hasNext()) {
    load(fi.next())
}

sudo apt-get build-dep python-mysqldb will install all the dependencies to build the package from PIP/easy_install

XmlSerializer sr = new XmlSerializer(objectToSerialize.GetType());
TextWriter xmlWriter = new StreamWriter(filename);
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
sr.Serialize(xmlWriter, objectToSerialize, namespaces);

You can also try to make service based on window.sessionStorage or window.localStorage to keep state information between page reloads. I use it in the web app which is partially made in AngularJS and page URL is changed in "the old way" for some parts of workflow. Web storage is supported even by IE8. Here is angular-webstorage for convenience.

Neither of the above answers worked for me, however this did

UPDATE:

As @doppleganger pointed out below, load is gone as of jQuery 3.0, so here's an updated version that uses on. Please note this will actually work on jQuery 1.7+, so you can implement it this way even if you're not on jQuery 3.0 yet.

$('iframe').on('load', function() {
    // do stuff 
});

Having included a dependency on spring-boot-configuration-processor in build.gradle:

annotationProcessor "org.springframework.boot:spring-boot-configuration-processor:2.4.1"

the only thing that worked for me, besides invalidating caches of IntelliJ and restarting, is

1. Refresh button in side panel Reload All Gradle Projects
2. Gradle task Clean
3. Gradle task Build

shuckc's answer for echoing select lines has a few downsides: you end up with the following set +x command being echoed as well, and you lose the ability to test the exit code with $? since it gets overwritten by the set +x.

Another option is to run the command in a subshell:

echo "getting URL..."
( set -x ; curl -s --fail $URL -o $OUTFILE )

if [ $? -eq 0 ] ; then
    echo "curl failed"
    exit 1
fi

which will give you output like:

getting URL...
+ curl -s --fail http://example.com/missing -o /tmp/example
curl failed

This does incur the overhead of creating a new subshell for the command, though.

Try the following in your view to check the output from each. The first one updates when the view is called a second time. My controller uses the key ShowCreateButton and has the optional parameter _createAction with a default value - you can change this to your key/parameter

@Html.TextBox("_createAction", null, new { Value = (string)ViewBag.ShowCreateButton })
@Html.TextBox("_createAction", ViewBag.ShowCreateButton )
@ViewBag.ShowCreateButton

Just for the record in modern times,

1 - Just have updated Xcode on your machine as you normally do

2 - Open terminal and

$ xcode-select --install

it will perform a short install of a minute or two.

3 - Launch Xcode. "New" "Project" ... you have to choose "Command line tool"

Note - confusingly this is under the "macOS" tab.

Select "C" language on the next screen...

4- You'll be asked to save the project somewhere on your desktop. The name you give the project here is just the name of the folder that will hold the project. It does not have any importance in the actual software.

5 - You're golden! You can now enjoy c with Mac and Xcode.

Try HttpClient for Java:

Somewhere you will need to set a fixed height, instead of using auto everywhere. You will find that if you set a fixed height on your content and/or container, then using auto for things inside it will work.

Also, your boxes will still expand height-wise with more content in, even though you have set a height for it - so don't worry about that :)

#container {
  height:500px;
  min-height:500px;
}

Here's an example:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def self.up
    rename_table :old_table_name, :new_table_name
  end

  def self.down
    rename_table :new_table_name, :old_table_name
  end
end

I had to go and rename the model declaration file manually.

Edit:

In Rails 3.1 & 4, ActiveRecord::Migration::CommandRecorder knows how to reverse rename_table migrations, so you can do this:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def change
    rename_table :old_table_name, :new_table_name
  end 
end

(You still have to go through and manually rename your files.)

For a more flexible solution, use the splice() function. It allows you to remove any item in an Array based on Index Value:

var indexToRemove = 0;
var numberToRemove = 1;

arr.splice(indexToRemove, numberToRemove);

UglifyJS2, used by the jQuery project.

It was really hard to remember that

    int numberOfColumns = arr.length;
    int numberOfRows = arr[0].length;

Let's understand why this is so and how we can figure this out when we're given an array problem. From the below code we can see that rows = 4 and columns = 3:

    int[][] arr = { {1, 1, 1, 1}, 

                    {2, 2, 2, 2}, 

                    {3, 3, 3, 3} };

arr has multiple arrays in it, and these arrays can be arranged in a vertical manner to get the number of columns. To get the number of rows, we need to access the first array and consider its length. In this case, we access [1, 1, 1, 1] and thus, the number of rows = 4. When you're given a problem where you can't see the array, you can visualize the array as a rectangle with n X m dimensions and conclude that we can get the number of rows by accessing the first array then its length. The other one (arr.length) is for the columns.

To have font variation working correctly, I had to reverse the order of @font-face in CSS.

@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}   
@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-Bold.ttf");
    font-weight: bold;
}
 @font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono.ttf");
}

My original submission was incorrect because it did not evaluate date for each line. Corrections have been made.

The -L 1 option causes xargs to process one line at a time instead of words.

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

Assuming you mean "file on a local filesystem" when you say .json file.

You'll need to save the json data formatted as jsonp, and use a file:// url to access it.

Your HTML will look like this:

<script src="file://c:\\data\\activity.jsonp"></script>
<script type="text/javascript">
  function updateMe(){
    var x = 0;
    var activity=jsonstr;
    foreach (i in activity) {
        date = document.getElementById(i.date).innerHTML = activity.date;
        event = document.getElementById(i.event).innerHTML = activity.event;
    }
  }
</script>

And the file c:\data\activity.jsonp contains the following line:

jsonstr = [ {"date":"July 4th", "event":"Independence Day"} ];

.cpp files are not included (using #include) into other files. Therefore they don't need include guarding. Main.cpp will know the names and signatures of the class that you have implemented in class.cpp only because you have specified all that in class.h - this is the purpose of a header file. (It is up to you to make sure that class.h accurately describes the code you implement in class.cpp.) The executable code in class.cpp will be made available to the executable code in main.cpp thanks to the efforts of the linker.

I know this is an old question but just for the record this can also be done by passing appropriate connection options as arguments to the _mysql.connect call. For example,

con = _mysql.connect(host='localhost', user='dell-pc', passwd='', db='test',
          connect_timeout=1000)

Notice the use of keyword parameters (host, passwd, etc.). They improve the readability of your code.

For detail about different arguments that you can pass to _mysql.connect, see MySQLdb API documentation

Having the same problem with unchecked checkboxes that will not be send on forms submit, I came out with a another solution than mirror the checkbox items.

Getting all unchecked checkboxes with

var checkboxQueryString;

$form.find ("input[type=\"checkbox\"]:not( \":checked\")" ).each(function( i, e ) {
  checkboxQueryString += "&" + $( e ).attr( "name" ) + "=N"
});

Updated (11/2017) to take into consideration some comments.

Easy example:

wchar_t buf[256];
FormatMessageW(FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
               NULL, GetLastError(), MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), 
               buf, (sizeof(buf) / sizeof(wchar_t)), NULL);

(This is for the benefit of others who may refer)

You can simply use cin and a char array. The cin input is delimited by the first whitespace it encounters.

#include<iostream>
using namespace std;

main()
{
    char word[50];
    cin>>word;
    while(word){
        //Do stuff with word[]
        cin>>word;
    }
}

class A{
public:
   static const char* SOMETHING() { return "something"; }
};

I do it all the time - especially for expensive const default parameters.

class A{
   static
   const expensive_to_construct&
   default_expensive_to_construct(){
      static const expensive_to_construct xp2c(whatever is needed);
      return xp2c;
   }
};

Here's a solid example of how a self invoking anonymous function could be useful.

for( var i = 0; i < 10; i++ ) {
  setTimeout(function(){
    console.log(i)
  })
}

Output: 10, 10, 10, 10, 10...

for( var i = 0; i < 10; i++ ) {
  (function(num){
    setTimeout(function(){
      console.log(num)
    })
  })(i)
}

Output: 0, 1, 2, 3, 4...

Try the following:

$("#list option[value=2]").text();

The reason why your original snippet wasn't working is because your OPTION tags are children to your SELECT tag, which has the id list.

The clearest way in my view is to use TimeSpan.FromTicks and then convert that to minutes:

TimeSpan ts = TimeSpan.FromTicks(ticks);
double minutes = ts.TotalMinutes;

If you are using HTML5 forms, you can use attribute min="0" for form element <input type="number" />. This is supported by all major browsers. It does not involve Javascript for such simple tasks, but is integrated in new html standard. It is documented on https://www.w3schools.com/tags/att_input_min.asp

If using ASP.NET Core MVC, add this to the ConfigureServices method of your startup.cs file:

services.AddMvc()
    .AddJsonOptions(
        options => options.SerializerSettings.ReferenceLoopHandling =            
        Newtonsoft.Json.ReferenceLoopHandling.Ignore
    );

On Linux (at least) you can set CHROME_LOG_FILE in the environment to have chrome write a log of the Console activity to the named file each time it runs. The log is overwritten every time chrome starts. This way, if you have an automated session that runs chrome, you don't have a to change the way chrome is started, and the log is there after the session ends.

export CHROME_LOG_FILE=chrome.log

Based on the answers by @James and @Jyotirmoy Bhattacharya I came up with this solution:

zx <- replicate (5, rnorm(50))
zx_means <- (colMeans(zx, na.rm = TRUE))
boxplot(zx, horizontal = FALSE, outline = FALSE)
points(zx_means, pch = 22, col = "darkgrey", lwd = 7)

(See this post for more details)

If you would like to add points to horizontal box plots, please see this post.

Hmmm I bet that in some previous lines you have something like:

list = set(something)

Am I wrong ?

if (input == undefined) { ... }

works just fine. It is of course not a null comparison, but I usually find that if I need to distinguish between undefined and null, I actually rather need to distinguish between undefined and just any false value, so

else if (input) { ... }

does it.

If a program redefines undefined it is really braindead anyway.

The only reason I can think of was for IE4 compatibility, it did not understand the undefined keyword (which is not actually a keyword, unfortunately), but of course values could be undefined, so you had to have this:

var undefined;

and the comparison above would work just fine.

In your second example, you probably need double parentheses to make lint happy?

One of the possible implementations:

File file = new File("userdata.xml");
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory
        .newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse(file);
String usr = document.getElementsByTagName("user").item(0).getTextContent();
String pwd = document.getElementsByTagName("password").item(0).getTextContent();

when used with the XML content:

<credentials>
    <user>testusr</user>
    <password>testpwd</password>
</credentials>

results in "testusr" and "testpwd" getting assigned to the usr and pwd references above.

Include the attribute Method="text" on the xsl:output tag and include newlines in your literal content in the XSL at the appropriate points. If you prefer to keep the source code of your XSL tidy use the entity 
 where you want a new line.

Single Line code for this.

var temp   =  DateTime.UtcNow.ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");

This answer is based on comments about devicePixelRatio coming back incorrectly on user1080381's answer.

I found that this command was coming back incorrectly in some instances too when working with a desktop, Surface Pro 3, and Surface Pro 4.

What I found is that it worked on my desktop, but the SP3 and SP4 were giving different numbers from each other and the desktop.

I noticed though that the SP3 was coming back as 1 and a half times the zoom level I was expecting. When I took a look at the display settings, the SP3 was actually set to 150% instead of the 100% I had on my desktop.

So, the solution to the comments should be to divide the returned zoom level by the scale of the machine you are currently on.

I was able to get the scale in the Windows settings by doing the following:

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DesktopMonitor");
double deviceScale = Convert.ToDouble(searcher.Get().OfType<ManagementObject>().FirstOrDefault()["PixelsPerXLogicalInch"]);
int standardPixelPerInch = 96;
return deviceScale / standardPixelPerInch;

So in the case of my SP3, this is how this code looks at 100% zoom:

devicePixelRatio = 1.5
deviceScale = 144
deviceScale / standardPixelPerInch = 1.5
devicePixelRatio / (deviceScale / standardPixelPerInch) = 1

Multiplying by the 100 in user1080381's original answer then would give you a zoom of 100 (%).

I realise this is an old thread, but for anyone who's interested in looking at this from a purely mathematical perspective, there's an excellent thread on the maths stack exchange, here:

https://math.stackexchange.com/questions/190111/how-to-check-if-a-point-is-inside-a-rectangle

Edit: Inspired by this thread, I've put together a simple vector method for quickly determining where your point lies.

Suppose you have a rectangle with points at p1 = (x1, y1), p2 = (x2, y2), p3 = (x3, y3) and p4 = (x4, y4), going clockwise. If a point p = (x, y) lies inside the rectangle, then the dot product (p - p1).(p2 - p1) will lie between 0 and |p2 - p1|^2, and (p - p1).(p4 - p1) will lie between 0 and |p4 - p1|^2. This is equivalent to taking the projection of the vector p - p1 along the length and width of the rectangle, with p1 as the origin.

This may make more sense if I show an equivalent code:

p21 = (x2 - x1, y2 - y1)
p41 = (x4 - x1, y4 - y1)

p21magnitude_squared = p21[0]^2 + p21[1]^2
p41magnitude_squared = p41[0]^2 + p41[1]^2

for x, y in list_of_points_to_test:

    p = (x - x1, y - y1)

    if 0 <= p[0] * p21[0] + p[1] * p21[1] <= p21magnitude_squared:
        if 0 <= p[0] * p41[0] + p[1] * p41[1]) <= p41magnitude_squared:
            return "Inside"
        else:
            return "Outside"
    else:
        return "Outside"

And that's it. It will also work for parallelograms.

I didn't need to set up remote debugging in order to get this working, I used Maven.

1. Ensure you have the Maven plugin installed into Eclipse.
2. Click Run > Run Configurations > Maven Build > new launch configuration:
   • Base directory: browse to the root of your project
   • Goals: spring-boot::run.
3. Click Apply then click Run.

NB. If your IDE has problems finding your project's source code when doing line-by-line debugging, take a look at this SO answer to find out how to manually attach your source code to the debug application.

Hope this helps someone!

there is also $log that you can use! it makes use of your console in a way that you want it to work!

showing the error/warning/info the way your console shows you normally!

use this > Document

select date_format(str_to_date('31/12/2010', '%d/%m/%Y'), '%Y%m'); 

or

select date_format(str_to_date('12/31/2011', '%m/%d/%Y'), '%Y%m'); 

hard to tell from your example

Since you are not worried about IE, why not just use css transitions to provide the animation and jQuery to change the classes. Live example: http://jsfiddle.net/tw16/JfK6N/

#someDiv{
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

The <appSettings> tag in web.config supports a file attribute that will load an external config with it's own set of key/values. These will override any settings you have in your web.config or add to them.

We take advantage of this by modifying our web.config at install time with a file attribute that matches the environment the site is being installed to. We do this with a switch on our installer.

eg;

<appSettings file=".\EnvironmentSpecificConfigurations\dev.config">

<appSettings file=".\EnvironmentSpecificConfigurations\qa.config">

<appSettings file=".\EnvironmentSpecificConfigurations\production.config">

Note:

• Changes to the .config specified by the attribute won't trigger a restart of the asp.net worker process

If you want to parse the format yourself you could do it easily with a regex such as

private static Pattern pattern = Pattern.compile("(\\d{2}):(\\d{2}):(\\d{2}).(\\d{3})");

public static long dateParseRegExp(String period) {
    Matcher matcher = pattern.matcher(period);
    if (matcher.matches()) {
        return Long.parseLong(matcher.group(1)) * 3600000L 
            + Long.parseLong(matcher.group(2)) * 60000 
            + Long.parseLong(matcher.group(3)) * 1000 
            + Long.parseLong(matcher.group(4)); 
    } else {
        throw new IllegalArgumentException("Invalid format " + period);
    }
}

However, this parsing is quite lenient and would accept 99:99:99.999 and just let the values overflow. This could be a drawback or a feature.

Your flex items have

flex: 0 0 200px; /* <aside> */
flex: 1 0 auto;  /* <article> */ 

That means:

• The <aside> will start at 200px wide.

  Then it won't grow nor shrink.

• The <article> will start at the width given by the content.

  Then, if there is available space, it will grow to cover it.

  Otherwise it won't shrink.

To prevent horizontal overflow, you can:

• Use flex-basis: 0 and then let them grow with a positive flex-grow.
• Use a positive flex-shrink to let them shrink if there isn't enough space.

To prevent vertical overflow, you can

• Use min-height instead of height to allow the flex items grow more if necessary
• Use overflow different than visible on the flex items
• Use overflow different than visible on the flex container

For example,

main, aside, article {
  margin: 10px;
  border: solid 1px #000;
  border-bottom: 0;
  min-height: 50px; /* min-height instead of height */
}
main {
  display: flex;
}
aside {
  flex: 0 1 200px; /* Positive flex-shrink */
}
article {
  flex: 1 1 auto; /* Positive flex-shrink */
}

<main>
  <aside>x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x </aside>
  <article>don't let flex item overflow container.... y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y </article>

If you are dealing with more dynamic screen resolution/sizes, instead of hardcoding the size in pixels you can change the width to a percentage of the media width as such

@media (min-width: 1200px) {
    .container{
        max-width: 70%;
   }
}

The

Probably there's something wrong with the input values for X and/or T. The function from the question works ok:

import numpy as np
from math import e

def sigmoid(X, T):
  return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))

X = np.array([[1, 2, 3], [5, 0, 0]])
T = np.array([[1, 2], [1, 1], [4, 4]])

print(X.dot(T))
# Just to see if values are ok
print([1. / (1. + e ** el) for el in [-5, -10, -15, -16]])
print()
print(sigmoid(X, T))

Result:

[[15 16]
 [ 5 10]]

[0.9933071490757153, 0.9999546021312976, 0.999999694097773, 0.9999998874648379]

[[ 0.99999969  0.99999989]
 [ 0.99330715  0.9999546 ]]

Probably it's the dtype of your input arrays. Changing X to:

X = np.array([[1, 2, 3], [5, 0, 0]], dtype=object)

Gives:

Traceback (most recent call last):
  File "/[...]/stackoverflow_sigmoid.py", line 24, in <module>

Be aware that a value of 1 equals 100% in Excel's interpretation. If you enter 5.66 and you want to show 5.66%, then AxGryndr's hack with the formatting will work, but it is a display format only and does not represent the true numeric value. If you want to use that percentage in further calculations, these calculations will return the wrong result unless you divide by 100 at calculation time.

The consistent and less error-prone way is to enter 0.0566 and format the number with the built-in percentage format. That way, you can easily calculate 5.6% of A1 by just multiplying A1 with the value.

The good news is that you don't need to go through the rigmarole of entering 0.0566 and then formatting as percent. You can simply type

5.66%

into the cell, including the percentage symbol, and Excel will take care of the rest and store the number correctly as 0.0566 if formatted as General.

The question is ambiguous: if the array may contain duplicate values, are you supposed to find the 2 largest distinct values or the two largest possibly identical values?

Your code seems to indicate you want the first approach, but you have a problem if the largest value is a[0]. You should use an extra boolean to keep track of whether you have found a different value yet.

You should also test the return value of the different scanf() calls and return 0 from main().

Here is a modified version:

#include <stdio.h>

int main(void) {
    int a[10], n, i;
    int largest1, largest2, has_largest2;

    printf("enter number of elements you want in array: ");
    if (scanf("%d", &n) != 1)
        return 1;
    if (n < 2) {
        printf("need at least 2 elements\n");
        return 1;
    }
    printf("enter elements: ");
    for (i = 0; i < n; i++) {
        if (scanf("%d", &a[i]) != 1) {
            printf("input error\n");
            return 1;
        }
    }
    largest1 = a[0];
    for (i = 1; i < n; i++) {
        if (a[i] > largest1) {
            largest1 = a[i];
        }
    }
    has_largest2 = largest2 = 0;
    for (i = 0; i < n; i++) {
        if (a[i] < largest1) {
            if (!has_largest2) {
                has_largest2 = 1;
                largest2 = a[i];
            } else
            if (a[i] > largest2) {
                largest2 = a[i];
            }
        }
    }
    if (has_largest2) {
        printf("First and second largest number is %d and %d\n",
               largest1, largest2);
    } else {
        printf("All values are identical to %d\n", largest1);
    }
    return 0;
}

As mentioned by ecdpalma below, git 1.7.12+ (August 2012) has enhanced the option --root for git rebase:

"git rebase [-i] --root $tip" can now be used to rewrite all the history leading to "$tip" down to the root commit.

That new behavior was initially discussed here:

I personally think "git rebase -i --root" should be made to just work without requiring "--onto" and let you "edit" even the first one in the history.
It is understandable that nobody bothered, as people are a lot less often rewriting near the very beginning of the history than otherwise.

The patch followed.

(original answer, February 2010)

As mentioned in the Git FAQ (and this SO question), the idea is:

1. Create new temporary branch
2. Rewind it to the commit you want to change using git reset --hard
3. Change that commit (it would be top of current HEAD, and you can modify the content of any file)

4. Rebase branch on top of changed commit, using:

   git rebase --onto <tmp branch> <commit after changed> <branch>`
   

The trick is to be sure the information you want to remove is not reintroduced by a later commit somewhere else in your file. If you suspect that, then you have to use filter-branch --tree-filter to make sure the content of that file does not contain in any commit the sensible information.

In both cases, you end up rewriting the SHA1 of every commit, so be careful if you have already published the branch you are modifying the contents of. You probably shouldn’t do it unless your project isn’t yet public and other people haven’t based work off the commits you’re about to rewrite.

With the help of raincoat's code on GitHub, I managed to get a running version accessing the clipboard with plain JavaScript.

function TrelloClipboard() {
    var me = this;

    var utils = {
        nodeName: function (node, name) {
            return !!(node.nodeName.toLowerCase() === name)
        }
    }

        if (!container) {
            container = document.createElement('div')

        container.style.display = 'none'
    }

    document.addEventListener('keydown', keyDownMonitor)
    document.addEventListener('keyup', keyUpMonitor)
}

Divider color:

It is a hack a bit, but it works great for me and it works without any external library (at least on Android 4.4).

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.dialog)
       .setIcon(R.drawable.ic)
       .setMessage(R.string.dialog_msg);
//The tricky part
Dialog d = builder.show();
int dividerId = d.getContext().getResources().getIdentifier("android:id/titleDivider", null, null);
View divider = d.findViewById(dividerId);
divider.setBackgroundColor(getResources().getColor(R.color.my_color));

You can find more dialog's ids in alert_dialog.xml file. Eg. android:id/alertTitle for changing title color...

UPDATE: Title color

Hack for changing title color:

int textViewId = d.getContext().getResources().getIdentifier("android:id/alertTitle", null, null);
TextView tv = (TextView) d.findViewById(textViewId);
tv.setTextColor(getResources().getColor(R.color.my_color));

Simply type the command:

$ gdb <Binary> <codeDump>

Or

$ gdb <binary>

$ gdb) core <coreDump>

There isn't any need to provide any command line argument. The code dump generated due to an earlier exercise.

I recently discovered q:. It opens the "command window" and shows your most recent ex-mode (command-mode) commands. You can move as usual within the window, and pressing <CR> executes the command. You can edit, etc. too. Priceless when you're messing around with some complex command or regex and you don't want to retype the whole thing, or if the complex thing you want to do was 3 commands back. It's almost like bash's set -o vi, but for vim itself (heh!).

See :help q: for more interesting bits for going back and forth.

   WebException we = (WebException)e.Error;
   HttpWebResponse response = (System.Net.HttpWebResponse)we.Response;
   if (response.StatusCode==HttpStatusCode.NotFound)
      System.Diagnostics.Debug.WriteLine("Not found!");
}

or

try
{
    // send request
}
catch (WebException e)
{
    // check e.Status as above etc..
}

I tried the above, (svn merge) and you're right, it does jack. However

svn update -r <revision> <target> [-R]

seems to work, but isn't permanent (my svn is simply showing an old revision). So I had to

mv <target> <target backup>
svn update <target>
mv <target backup> <target>
svn commit -m "Reverted commit on <target>" <target>

In my particular case my target is interfaces/AngelInterface.php. I made changes to the file, committed them, updated the build computer ran the phpdoc compiler and found my changes were a waste of time. svn log interfaces/AngelInterface.php shows my change as r22060 and the previous commit on that file was r22059. So I can svn update -r 22059 interfaces/AngelInterface.php and I end up with code as it was in -r22059 again. Then :-

mv interfaces/AngelInterface.php interfaces/AngelInterface.php~
svn update interfaces/AngelInterface.php
mv interfaces/AngelInterface.php~ interfaces/AngelInterface.php
svn commit -m "reverted -r22060" interfaces/AngelInterface.php

Alternatively I could do the same thing on a directory, by specifying . -R in place of interfaces/AngelInterface.php in all the above.

In your CSS file, such as App.css in a create-react-app, add a fontface import. For example:

@fontface {
  font-family: 'Bungee Inline', cursive;
  src: url('https://fonts.googleapis.com/css?family=Bungee+Inline')
}

Then simply add the font to the DOM element within the same css file.

body {
  font-family: 'Bungee Inline', cursive;
}

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

Adding to previous answers, it is valid Ruby to use :: to access instance methods. All the following are valid:

MyClass::new::instance_method
MyClass::new.instance_method
MyClass.new::instance_method
MyClass.new.instance_method

_{As per best practices I believe only the last one is recommended.}

I asked a similar question here and got a fantastic answer - use the iPhone native datepicker - it's great.

How to turn off iPhone keypad for a specified input field on web page

Synopsis / pseudo-code:

if small screen mobile device 

  set field type to "date" - e.g. document.getElementById('my_field').type = "date";
  // input fields of type "date" invoke the iPhone datepicker.

else

  init datepicker - e.g. $("#my_field").datepicker();

The reason for dynamically setting the field type to "date" is that Opera will pop up its own native datepicker otherwise, and I'm assuming you want to show the datepicker consistently on desktop browsers.

I had the same problem:

As I was reluctant to give 0777 to my php directory, I create a tmp directory with rights 0777, where I create the files I need to write to.

My php directory continue to be protected. If somebody hackes the tmp directory, the site continue to work as usual.

I had to add one more line to REVOKE...

After running:

REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA public FROM username;
REVOKE ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public FROM username;
REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public FROM username;

I was still receiving the error: username cannot be dropped because some objects depend on it DETAIL: privileges for schema public

I was missing this:

REVOKE USAGE ON SCHEMA public FROM username;

Then I was able to drop the role.

DROP USER username;

For Tomcat v8.5.4 and above, the file <tomcat>/webapps/manager/META-INF/context.xml has been adjusted:

<Context antiResourceLocking="false" privileged="true" >
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
</Context>

Change this file to comment the Valve:

<Context antiResourceLocking="false" privileged="true" >
    <!--
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
    -->
</Context>

After that, refresh your browser (not need to restart Tomcat), you can see the manager page.

This depends on your spring boot version:

When SpringBootVersion <= 1.2 then use error.whitelabel.enabled = false

When SpringBootVersion >= 1.3 then use server.error.whitelabel.enabled = false

I had a similar problem . For this you can use a Hashmap which takes "string" and "object" as shown in code below:

/** stores the image database icons */
public static int[] imageIconDatabase = { R.drawable.ball,
        R.drawable.catmouse, R.drawable.cube, R.drawable.fresh,
        R.drawable.guitar, R.drawable.orange, R.drawable.teapot,
        R.drawable.india, R.drawable.thailand, R.drawable.netherlands,
        R.drawable.srilanka, R.drawable.pakistan,

};
private void initializeImageList() {
    // TODO Auto-generated method stub
    for (int i = 0; i < imageIconDatabase.length; i++) {
        map = new HashMap<String, Object>();

        map.put("Name", imageNameDatabase[i]);
        map.put("Icon", imageIconDatabase[i]);
    }

}

Super simple:

Press the F5 key and the code will run.

If a breakpoint is set, pressing F5 will stop at the breakpoint and run the code in debug mode.

Other Method - To add Shortcut

Note: You must have Python Extension By Microsoft installed in Visual Studio Code, and the Python interpreter selected in the lower-left corner.

Go to File ? Preferences ? Keyboard Shortcuts (alternatively, you can press Ctrl + K + S) In the search box, enter python.execInTerminal Double click that result (alternatively, you can click the plus icon) Press Ctrl + Alt + B to register this as the keybinding (alternatively, you can enter your own keybinding)

Now you can close the Keyboard Shortcuts tab Go to the Python file you want to run and press Ctrl + Alt + B (alternatively, you can press the keybinding you set) to run it. The output will be shown in the bottom terminal tab.

(ps: the answer given by Nick Craver is incorrect)

contentType specifies the format of data being sent to the server as part of request(it can be sent as part of response too, more on that later).

dataType specifies the expected format of data to be received by the client(browser).

Both are not interchangable.

• contentType is the header sent to the server, specifying the format of data(i.e the content of message body) being being to the server. This is used with POST and PUT requests. Usually when u send POST request, the message body comprises of passed in parameters like:

==============================

Sample request:

POST /search HTTP/1.1 
Content-Type: application/x-www-form-urlencoded 
<<other header>>

name=sam&age=35

==============================

The last line above "name=sam&age=35" is the message body and contentType specifies it as application/x-www-form-urlencoded since we are passing the form parameters in the message body. However we aren't limited to just sending the parameters, we can send json, xml,... like this(sending different types of data is especially useful with RESTful web services):

==============================

Sample request:

POST /orders HTTP/1.1
Content-Type: application/xml
<<other header>>

<order>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

So the ContentType this time is: application/xml, cause that's what we are sending. The above examples showed sample request, similarly the response send from the server can also have the Content-Type header specifying what the server is sending like this:

==============================

sample response:

HTTP/1.1 201 Created
Content-Type: application/xml
<<other headers>>

<order id="233">
   <link rel="self" href="http://example.com/orders/133"/>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

• dataType specifies the format of response to expect. Its related to Accept header. JQuery will try to infer it based on the Content-Type of the response.

==============================

Sample request:

GET /someFolder/index.html HTTP/1.1
Host: mysite.org
Accept: application/xml
<<other headers>>

==============================

Above request is expecting XML from the server.

Regarding your question,

contentType: "application/json; charset=utf-8",
dataType: "json",

Here you are sending json data using UTF8 character set, and you expect back json data from the server. As per the JQuery docs for dataType,

The json type parses the fetched data file as a JavaScript object and returns the constructed object as the result data.

So what you get in success handler is proper javascript object(JQuery converts the json object for you)

whereas

contentType: "application/json",
dataType: "text",

Here you are sending json data, since you haven't mentioned the encoding, as per the JQuery docs,

If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and since dataType is specified as text, what you get in success handler is plain text, as per the docs for dataType,

The text and xml types return the data with no processing. The data is simply passed on to the success handler

As an exercise, I would suggest doing the following:

public void save(String fileName) throws FileNotFoundException {
    PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
    for (Club club : clubs)
        pw.println(club.getName());
    pw.close();
}

This will write the name of each club on a new line in your file.

Soccer
Chess
Football
Volleyball
...

I'll leave the loading to you. Hint: You wrote one line at a time, you can then read one line at a time.

Every class in Java extends the Object class. As such you can override its methods. In this case, you should be interested by the toString() method. In your Club class, you can override it to print some message about the class in any format you'd like.

public String toString() {
    return "Club:" + name;
}

You could then change the above code to:

public void save(String fileName) throws FileNotFoundException {
    PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
    for (Club club : clubs)
         pw.println(club); // call toString() on club, like club.toString()
    pw.close();
}

You can use this simply:

I'm using this function to check if the input int number is between 20 and 30

    static boolean isValidInput(int input) {
    return (input >= 20 && input <= 30);
}

If your app is a system app,you can use PowerManager.goToSleep() to turn screen off,you requires a special permission

before you use goToSleep(), you need use reflection just like:

public static void goToSleep(Context context) {
    PowerManager powerManager= (PowerManager)context.getSystemService(Context.POWER_SERVICE);
    try {
        powerManager.getClass().getMethod("goToSleep", new Class[]{long.class}).invoke(powerManager, SystemClock.uptimeMillis());
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    }
}

Now,you can use goToSleep() to turn screen off.

This is what happens when the power key is pressed to turn off the screen.

You can use the simple/lightweight ng-file-upload directive. It supports drag&drop, file progress and file upload for non-HTML5 browsers with FileAPI flash shim

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directive.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', 'Upload', function($scope, Upload) {
  $scope.onFileSelect = function($files) {
  Upload.upload({
    url: 'my/upload/url',
    file: $files,            
  }).progress(function(e) {
  }).then(function(data, status, headers, config) {
    // file is uploaded successfully
    console.log(data);
  }); 

}];

If you have any function associated to list ,when you make the splice function, the association is deleted too. My solution:

$scope.remove = function() {
    var oldList = $scope.items;
    $scope.items = [];

    angular.forEach(oldList, function(x) {
        if (! x.done) $scope.items.push( { [ DATA OF EACH ITEM USING oldList(x) ] });
    });
};

The list param is named items. The param x.done indicate if the item will be deleted. Hope help you. Greetings.

you don’t need a select … from dual, just write:

SELECT t.*, dbms_random.value(1,9) RandomNumber
  FROM myTable t

To add ANDROID_HOME value permanently,

gedit ~/.bashrc

and add the following lines

export ANDROID_HOME=/root/Android/Sdk
PATH=$PATH:$ANDROID_HOME/tools

Save the file and you need not update ANDROID_HOME value everytime.

you can do this by setting the date of expiry to yesterday.

As Niklas mentioned you can use the html2canvas library to take a screenshot using JS in the browser. I will extend his answer in this point by providing an example of taking a screenshot using this library ("Proof of Concept"):

function report() {
  let region = document.querySelector("body"); // whole screen
  html2canvas(region, {
    onrendered: function(canvas) {
      let pngUrl = canvas.toDataURL(); // png in dataURL format
      let img = document.querySelector(".screen");
      img.src = pngUrl; 

      // here you can allow user to set bug-region
      // and send it with 'pngUrl' to server
    },
  });
}

.container {
  margin-top: 10px;
  border: solid 1px black;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
<div>Screenshot tester</div>
<button onclick="report()">Take screenshot</button>

<div class="container">
  <img width="75%" class="screen">
</div>

In report() function in onrendered after getting image as data URI you can show it to the user and allow him to draw "bug region" by mouse and then send a screenshot and region coordinates to the server.

In this example async/await version was made: with nice makeScreenshot() function.

UPDATE

Simple example which allows you to take screenshot, select region, describe bug and send POST request (here jsfiddle) (the main function is report()).

async function report() {
    let screenshot = await makeScreenshot(); // png dataUrl
    let img = q(".screen");
    img.src = screenshot; 
    
    let c = q(".bug-container");
    c.classList.remove('hide')
        
    let box = await getBox();    
    c.classList.add('hide');

    send(screenshot,box); // sed post request  with bug image, region and description
    alert('To see POST requset with image go to: chrome console > network tab');
}

// ----- Helper functions

let q = s => document.querySelector(s); // query selector helper
window.report = report; // bind report be visible in fiddle html

async function  makeScreenshot(selector="body") 
{
  return new Promise((resolve, reject) => {  
    let node = document.querySelector(selector);
    
    html2canvas(node, { onrendered: (canvas) => {
        let pngUrl = canvas.toDataURL();      
        resolve(pngUrl);
    }});  
  });
}

async function getBox(box) {
  return new Promise((resolve, reject) => {
     let b = q(".bug");
     let r = q(".region");
     let scr = q(".screen");
     let send = q(".send");
     let start=0;
     let sx,sy,ex,ey=-1;
     r.style.width=0;
     r.style.height=0;
     
     let drawBox= () => {
         r.style.left   = (ex > 0 ? sx : sx+ex ) +'px'; 
         r.style.top    = (ey > 0 ? sy : sy+ey) +'px';
         r.style.width  = Math.abs(ex) +'px';
         r.style.height = Math.abs(ey) +'px'; 
     }
     
     
     
     //console.log({b,r, scr});
     b.addEventListener("click", e=>{

           drawBox(); 
       }
     });
     
     send.addEventListener("click", e=>{
       start=0;
       let a=100/75 //zoom out img 75%

You're trying to concatenate a string and an integer, which is incorrect.

Change print(numlist.pop(2)+" has been removed") to any of these:

Explicit int to str conversion:

print(str(numlist.pop(2)) + " has been removed")

Use , instead of +:

print(numlist.pop(2), "has been removed")

String formatting:

print("{} has been removed".format(numlist.pop(2)))

Creating both header and footer, here is an example:

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

My method of doing this has been to create an inherited class that explicitly implements IDisposable. This is useful for folks who use the gui to add the service reference ( Add Service Reference ). I just drop this class in the project making the service reference and use it instead of the default client:

using System;
using System.ServiceModel;
using MyApp.MyService; // The name you gave the service namespace

namespace MyApp.Helpers.Services
{
    public class MyServiceClientSafe : MyServiceClient, IDisposable
    {
        void IDisposable.Dispose()
        {
            if (State == CommunicationState.Faulted)
            {
                Abort();
            }
            else if (State != CommunicationState.Closed)
            {
                Close();
            }

            // Further error checks and disposal logic as desired..
        }
    }
}

Note: This is just a simple implementation of dispose, you can implement more complex dispose logic if you like.

You can then replace all your calls made with the regular service client with the safe clients, like this:

using (MyServiceClientSafe client = new MyServiceClientSafe())
{
    var result = client.MyServiceMethod();
}

I like this solution as it does not require me to have access to the Interface definitions and I can use the using statement as I would expect while allowing my code to look more or less the same.

You will still need to handle the exceptions which can be thrown as pointed out in other comments in this thread.

For those having issues with the command line SDK, the reason it won't find the licenses you have accepted is because they have have been written to a different location than $ANDROID_HOME/licenses which is where they need to be.

I found the easiest solution was to accept the licenses like this:

$ANDROID_HOME/bin/sdkmanager --licenses --sdk_root=$ANDROID_HOME

Note: This assumes you've set ANDROID_HOME to point to wherever your sdk is installed.

That's how I do it:

Since your have free choise about DB type use a filebased DB like e.g. firebird.

Create a template DB which has the schema that fits your actual branch and store it in your repository.

When executing your application programmatically create a copy of your template DB, store it somewhere else and just work with that copy.

This way you can put your DB schema under version control without the data. And if you change your schema you just have to change the template DB

dictionary["C1"]=map(lambda x:x+10,dictionary["C1"]) 

Should do it...

 if(checkBox.getAttribute("checked") != null) // if Checked 
    checkBox.click();                         //to Uncheck it 

You can also add an and statement to be sure if checked is true.

Take a look at the history of "foobar" on Wikipedia.

There is not a pure scanf replacement in standard Java, but you could use a java.util.Scanner for the same problems you would use scanf to solve.

Similar to the solution listed above with Notepad, you can also open the file in Visual Studio, if you're using that. In Visual Studio, you can select "File > Advanced Save Options..."

The "Encoding:" combo box will tell you specifically which encoding is currently being used for the file. It has a lot more text encodings listed in there than Notepad does, so it's useful when dealing with various files from around the world and whatever else.

Just like Notepad, you can also change the encoding from the list of options there, and then saving the file after hitting "OK". You can also select the encoding you want through the "Save with Encoding..." option in the Save As dialog (by clicking the arrow next to the Save button).

Steps to Create Radio Button

BasicStep : take Two Button. set image for both like selected and unselected. than add action to both button. now start code

1)Create variable :

var btnTag    : Int = 0

2)In ViewDidLoad Define :

 btnTag = btnSelected.tag

3)Now In Selected Tap Action :

 @IBAction func btnSelectedTapped(sender: AnyObject) {
    btnTag = 1
    if btnTag == 1 {
      btnSelected.setImage(UIImage(named: "icon_radioSelected"), forState: .Normal)
      btnUnSelected.setImage(UIImage(named: "icon_radioUnSelected"), forState: .Normal)
     btnTag = 0

4)Do code for UnCheck Button

 @IBAction func btnUnSelectedTapped(sender: AnyObject) {
    btnTag = 1
    if btnTag == 1 {
        btnUnSelected.setImage(UIImage(named: "icon_radioSelected"), forState: .Normal)
        btnSelected.setImage(UIImage(named: "icon_radioUnSelected"), forState: .Normal)
        btnTag = 0
    }
}

Radio Button is Ready for you

OK, for me that is the way it worked (I am using Python 2.7):

a = __import__('file_to_import', globals(), locals(), ['*'], -1)
b = a.MyClass()

Then, b is an instance of class 'MyClass'

The & makes the command run in the background.

From man bash:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0.

If you just want to show label below the marker, then you can extend google maps Marker to add a setter method for label and you can define the label object by extending google maps overlayView like this..

<script type="text/javascript">
    var point = { lat: 22.5667, lng: 88.3667 };
    var markerSize = { x: 22, y: 40 };


    google.maps.Marker.prototype.setLabel = function(label){
        this.label = new MarkerLabel({
          map: this.map,
          marker: this,
          text: label
        });
        this.label.bindTo('position', this, 'position');
    };

    var MarkerLabel = function(options) {
        this.setValues(options);
        this.span = document.createElement('span');
        this.span.className = 'map-marker-label';
    };

    MarkerLabel.prototype = $.extend(new google.maps.OverlayView(), {
        onAdd: function() {
            this.getPanes().overlayImage.appendChild(this.span);
            var self = this;
            this.listeners = [
            google.maps.event.addListener(this, 'position_changed', function() { self.draw();    })];
        },
        draw: function() {
            var text = String(this.get('text'));
            var position = this.getProjection().fromLatLngToDivPixel(this.get('position'));
            this.span.innerHTML = text;
            this.span.style.left = (position.x - (markerSize.x / 2)) - (text.length * 3) + 10 + 'px';
            this.span.style.top = (position.y - markerSize.y + 40) + 'px';
        }
    });
    function initialize(){
        var myLatLng = new google.maps.LatLng(point.lat, point.lng);
        var gmap = new google.maps.Map(document.getElementById('map_canvas'), {
            zoom: 5,
            center: myLatLng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });
        var myMarker = new google.maps.Marker({
            map: gmap,
            position: myLatLng,
            label: 'Hello World!',
            draggable: true
        });
    }
</script>
<style>
    .map-marker-label{
        position: absolute;
    color: blue;
    font-size: 16px;
    font-weight: bold;
    }
</style>

This will work.

You just need to manually set the desired permissions with chmod():

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);

    // Set perms with chmod()
    chmod($file, 0777);
    return true;
}

You can use os.system to invoke terminal to accomplish the task:

os.system('mv oldfile newfile')

Confining Mutability to Builders

The top answers here correctly speak to the difference in Kotlin between read-only List (NOTE: it's read-only, not "immutable"), and MutableList.

In general, one should strive to use read-only lists, however, mutability is still often useful at construction time, especially when dealing with third-party libraries with non-functional interfaces. For cases in which alternate construction techniques are not available, such as using listOf directly, or applying a functional construct like fold or reduce, a simple "builder function" construct like the following nicely produces a read-only list from a temporary mutable one:

val readonlyList = mutableListOf<...>().apply {
  // manipulate your list here using whatever logic you need
  // the `apply` function sets `this` to the `MutableList`
  add(foo1)
  addAll(foos)
  // etc.
}.toList()

and this can be nicely encapsulated into a re-usable inline utility function:

inline fun <T> buildList(block: MutableList<T>.() -> Unit) = 
  mutableListOf<T>().apply(block).toList()

which can be called like this:

val readonlyList = buildList<String> {
  add("foo")
  add("bar")
}

Now, all of the mutability is isolated to one block scope used for construction of the read-only list, and the rest of your code uses the read-only list that is output from the builder.

UPDATE: As of Kotlin 1.3.70, the exact buildList function above is available in the standard library as an experimental function, along with its analogues buildSet and buildMap. See https://blog.jetbrains.com/kotlin/2020/03/kotlin-1-3-70-released/.

simple and easier solution:

select extract(hour from systimestamp) from dual;

EXTRACT(HOURFROMSYSTIMESTAMP)
-----------------------------
                           16 

If you go into any of those locations, then you will find what is defined in those schema. For example, it tells you what is the data type of the ini-method key words value.

The servlet class should be in the WEB-INF/classes not WEB-INF/src.

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

It is privacy concern. It is recommended to disallow users to backup an app if it contains sensitive data. Having access to backup files (i.e. when android:allowBackup="true"), it is possible to modify/read the content of an app even on a non-rooted device.

Solution - use android:allowBackup="false" in the manifest file.

I had this error once and I found out the origin:

I was using a gcc compiler and my file was called CLIENT.C despite I was doing a C program and not a C++ program.

gcc recognizes the .C extension as C++ program and .c extension as C program (be careful to the small c and big C).

So I renamed my file CLIENT.c program and it worked.

window.location.href = "URL2"

inside a JS block on the page or in an included file; that's assuming you really want to do it on the client. Usually, the server sends the redirect via a 300-series response.

echo : echo is a language construct where there is not required to use parentheses with it and it can take any number of parameters and return void.

   void echo (param1,param2,param3.....);

   Example: echo "test1","test2,test3";

print : it is a language construct where there is not required to use parentheses it just take one parameter and return

    1 always.

           int print(param1);

           print "test1";
           print "test1","test2"; // It will give syntax error

prinf : It is a function which takes atleast one string and format style and returns length of output string.

    int printf($string,$s);

    $s= "Shailesh";
    $i= printf("Hello %s how are you?",$s);    
    echo $i;

    Output : Hello Shailesh how are you?
             27



   echo returns void so its execution is faster than print and printf

Setting the Content-Type header will affect how a web browser treats your content. When most mainstream web browsers encounter a Content-Type of text/plain, they'll render the raw text source in the browser window (as opposed to the source rendered at HTML). It's the difference between seeing

<b>foo</b>

or

foo

Additionally, when using the XMLHttpRequest object, your Content-Type header will affect how the browser serializes the returned results. Prior to the takeover of AJAX frameworks like jQuery and Prototype, a common problem with AJAX responses was a Content-Type set to text/html instead of text/xml. Similar problems would likely occur if the Content-Type was text/plain.

Have you considered using span instead of div? It is the in-line version of div.

I use ? (0x25B8) for the right arrow, often to show a collapsed list; and I pair it with ? (0x25BE) to show the list opened up. Both are unobtrusive.

I solved that problem by using a special setting for JsonSerializerSettings which is called TypeNameHandling.All

TypeNameHandling setting includes type information when serializing JSON and read type information so that the create types are created when deserializing JSON

Serialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var text = JsonConvert.SerializeObject(configuration, settings);

Deserialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var configuration = JsonConvert.DeserializeObject<YourClass>(json, settings);

The class YourClass might have any kind of base type fields and it will be serialized properly.

I just hit this and the problem was that the package had at one point been installed in the per-user packages directory. (On Windows.) aka %AppData%\Python. So Python was looking there first, finding an old 32-bit version of the .pyd file, and failing with the listed error. Unfortunately pip uninstall by itself wasn't enough to clean this, and at this time pip 10.0.1 doesn't seem to have a --user parameter for uninstall, only for install.

tl;dr Deleting the old .pyd from %AppData%\python\python27\site-packages resolved this problem for me.

How about creating your own Custom Panel class? That way you won't have to worry about overriding Bootstrap.

HTML

<div class="panel panel-custom-horrible-red">
   <div class="panel-heading">

   </div>
   <div class="panel-body">

    border-color: #ff0000;
}
.panel-custom-horrible-red > .panel-heading {
    background: #ff0000; 
    color: #ffffff;
    border-color: #ff0000;
}

According to the standard, you should be safe with that assumption. The C++ bool type has two values - true and false with corresponding values 1 and 0.

The thing to watch about for is mixing bool expressions and variables with BOOL expression and variables. The latter is defined as FALSE = 0 and TRUE != FALSE, which quite often in practice means that any value different from 0 is considered TRUE.

A lot of modern compilers will actually issue a warning for any code that implicitly tries to cast from BOOL to bool if the BOOL value is different than 0 or 1.

I solved this by copying it over to the missing directory:

cp /opt/X11/lib/libpng15.15.dylib /usr/local/lib/libpng15.15.dylib

brew reinstall libpng kept installing libpng16, not libpng15 so I was forced to do the above.

This happened to me suddenly because my app's distribution profile had expired. Xcode began using the wildcard profile instead, which did not have the push notification entitlement enabled. I didn't receive any warning. The fix was easy; I just had to generate another distribution profile for my app in the Apple Developer Member Center, download it, and double-click to install in Xcode.

It is true that, functionally, both queries should be processed the same way. However, experience has shown that if you are selecting from views that use the new join syntax, it is important to structure your queries using it as well. Oracle's optimizer can get confused if a view uses a "join" statement, but a query accessing the view uses the traditional method of joining in the "where" clause.

Try checking if you can establish handshake in the first place. I had this issue before when uploading a file and I only figured out that the issue was the nonexistent route when I removed the upload and checked if it can login given the parameters.

public static void main(String[] args) {

    int[] A=new int[size];
      //code for take input in array
      int[] C=sorting(A); //pass array via method
      //and then print array

    }
public static int[] sorting(int[] a) {
     //code for work with array 
     return a; //retuen array
}

It needs both jni.h and jni_md.h files, Try this

gcc -I/usr/lib/jvm/jdk1.7.0_07/include \
  -I/usr/lib/jvm/jdk1.7.0_07/include/linux filename.c

This will include both the broad JNI files and the ones necessary for linux

The best answer works perfectly fine but in most cases, it is overkill and inefficient to loop through all the label elements.

Here is an efficent function to get the label that goes with the input element:

function getLabelForInput(id)
{
    var el = document.getElementById(id);
    if (!el)
        return null;
    var elPrev = el.previousElementSibling;
    var elNext = el.nextElementSibling;
    while (elPrev || elNext)
    {
        if (elPrev)
        {
            if (elPrev.htmlFor === id)
                return elPrev;
            elPrev = elPrev.previousElementSibling;
        }
        if (elNext)
        {
            if (elNext.htmlFor === id)
                return elNext;
            elNext = elNext.nextElementSibling;
        }
    }
    return null;
}

For me, this one line of code was sufficient:

el = document.getElementById(id).previousElementSibling;

In most cases, the label will be very close or next to the input, which means the loop in the above function only needs to iterate a very small number of times.

I'd do it like this:

sudo chown -R $USER:www-data laravel-project/ 

find laravel-project/ -type f -exec chmod 664 {} \;

find laravel-project/ -type d -exec chmod 775 {} \;

then finally, you need to give webserver permission to modify the storage and bootstrap/cache directories:

sudo chgrp -R www-data storage bootstrap/cache
sudo chmod -R ug+rwx storage bootstrap/cache

I've checked DamienG's answer in LinqPad. Instead of

g.Group.Max(s => s.uid)

should be

g.Max(s => s.uid)

Thank you!

You can use C#, Javascript, Boo.

Unless computing requirement for the function you write cause heavy load on processor, Javascript gives good enough performance for most cases.

Use Map<Integer, List<String>>:

Map<Integer, List<String>> map = new LinkedHashMap< Integer, List<String>>();

map.put(-1505711364, new ArrayList<>(Arrays.asList("4")));
map.put(294357273, new ArrayList<>(Arrays.asList("15", "71")));
//...

To add a new key/value pair in this map:

public void add(Integer key, String newValue) {
    List<String> currentValue = map.get(key);
    if (currentValue == null) {
        currentValue = new ArrayList<String>();
        map.put(key, currentValue);
    }
    currentValue.add(newValue);
}

As specified in oracle official tutorial , it states that:

If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception.

If I have an Application interacting with database using JDBC , And I have a method that takes the argument as the int item and double price. The price for corresponding item is read from database table. I simply multiply the total number of item purchased with the price value and return the result. Although I am always sure at my end(Application end) that price field value in the table could never be negative .But what if the price value comes out negative? It shows that there is a serious issue with the database side. Perhaps wrong price entry by the operator. This is the kind of issue that the other part of application calling that method can't anticipate and can't recover from it. It is a BUG in your database. So , and IllegalArguementException() should be thrown in this case which would state that the price can't be negative.
I hope that I have expressed my point clearly..

Part 3 - Tricks and Efficient Code

MySQL in() efficiency

I thought I would add some extra bits, for tips and tricks that have come up.

One question I see come up a fair bit, is How do I get non-matching rows from two tables and I see the answer most commonly accepted as something like the following (based on our cars and brands table - which has Holden listed as a brand, but does not appear in the cars table):

select
    a.ID,
    a.brand
from
    brands a
where
    a.ID not in(select brand from cars)

And yes it will work.

+----+--------+
| ID | brand  |
+----+--------+
|  6 | Holden |
+----+--------+
1 row in set (0.00 sec)

However it is not efficient in some database. Here is a link to a Stack Overflow question asking about it, and here is an excellent in depth article if you want to get into the nitty gritty.

The short answer is, if the optimiser doesn't handle it efficiently, it may be much better to use a query like the following to get non matched rows:

select
    a.brand
from
    brands a
        left join cars b
            on a.id=b.brand
where
    b.brand is null

+--------+
| brand  |
+--------+
| Holden |
+--------+
1 row in set (0.00 sec)

Update Table with same table in subquery

Ahhh, another oldie but goodie - the old You can't specify target table 'brands' for update in FROM clause.

MySQL will not allow you to run an update... query with a subselect on the same table. Now, you might be thinking, why not just slap it into the where clause right? But what if you want to update only the row with the max() date amoung a bunch of other rows? You can't exactly do that in a where clause.

update 
    brands 
set 
    brand='Holden' 
where 
    id=
        (select 
            id 
        from 
            brands 
        where 
            id=6);
ERROR 1093 (HY000): You can't specify target table 'brands' 
for update in FROM clause

So, we can't do that eh? Well, not exactly. There is a sneaky workaround that a surprisingly large number of users don't know about - though it does include some hackery that you will need to pay attention to.

You can stick the subquery within another subquery, which puts enough of a gap between the two queries so that it will work. However, note that it might be safest to stick the query within a transaction - this will prevent any other changes being made to the tables while the query is running.

update 
    brands 
set 
    brand='Holden' 
where id=
    (select

set your CssClass property in textbox1 to "cupper", then in page content create new css class :

<style type="text/css">.cupper {text-transform:uppercase;}</style>

Then, enjoy it ...

A good rule of thumb: use the built-in help system in Python. Example below...

jdoe@server:~$ python
Python 2.7.3 (default, Aug  1 2012, 05:14:39) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

NAME
    memcache - client module for memcached (memory cache daemon)

FILE
    /usr/lib/python2.7/dist-packages/memcache.py

MODULE DOCS
    http://docs.python.org/library/memcache

DESCRIPTION
    Overview
    ========

    See U{the MemCached homepage<http://www.danga.com/memcached>} for more about memcached.

    Usage summary
    =============
...
------------------------------------------

I know its old but

public class SwitchTest {
static final int max = 100000;

public static void main(String[] args) {

int counter1 = 0;
long start1 = 0l;
long total1 = 0l;

int counter2 = 0;
long start2 = 0l;
long total2 = 0l;
boolean loop = true;

start1 = System.currentTimeMillis();
while (true) {
  if (counter1 == max) {
    break;
  } else {
    counter1++;
  }
}
total1 = System.currentTimeMillis() - start1;

start2 = System.currentTimeMillis();
while (loop) {
  switch (counter2) {
    case max:
      loop = false;
      break;
    default:
      counter2++;
  }
}
total2 = System.currentTimeMillis() - start2;

System.out.println("While if/else: " + total1 + "ms");
System.out.println("Switch: " + total2 + "ms");
System.out.println("Max Loops: " + max);

System.exit(0);
}
}

Varying the loop count changes a lot:

While if/else: 5ms Switch: 1ms Max Loops: 100000

While if/else: 5ms Switch: 3ms Max Loops: 1000000

While if/else: 5ms Switch: 14ms Max Loops: 10000000

While if/else: 5ms Switch: 149ms Max Loops: 100000000

(add more statements if you want)

You need to update your virtualbox sw. On new version, there is VBoxDarwinAdditions.pkg included in a additions iso image, in older versions is missing.

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

this worked for me:

SELECT pg_catalog.setval('public.hibernate_sequence', 3, true);

As user1767754 said, the key here is to not make any selection initially.

Just place the cursor inside the variable name, don't double click to select it. For single character variables, place the cursor at the front or end of the variable to not make any selection initially.

Now keep hitting Cmd+D for next variable selection or Ctrl+Cmd+G for selecting all variables at once. It will magically select only the variables.

The following is building on Eran's code, with a few minor changes. Tested it and it seems to work fine on Firefox 3, IE7.

You could use "typeof".

if(typeof maybeObject != "undefined")
    alert("GOT HERE");

Something that is now available in maven as well is

mvn goal --no-snapshot-updates

or in short

mvn goal -nsu

The SQL:2003 standard changed some precedence rules so a JOIN statement takes precedence over a "comma" join. This can actually change the results of your query depending on how it is setup. This cause some problems for some people when MySQL 5.0.12 switched to adhering to the standard.

So in your example, your queries would work the same. But if you added a third table: SELECT ... FROM table1, table2 JOIN table3 ON ... WHERE ...

Prior to MySQL 5.0.12, table1 and table2 would be joined first, then table3. Now (5.0.12 and on), table2 and table3 are joined first, then table1. It doesn't always change the results, but it can and you may not even realize it.

I never use the "comma" syntax anymore, opting for your second example. It's a lot more readable anyway, the JOIN conditions are with the JOINs, not separated into a separate query section.

I would use the RadioButtons in a ListBox, and then bind to the SelectedValue.

This is an older thread about this topic, but the base idea should be the same: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/323d067a-efef-4c9f-8d99-fecf45522395/

Just an update since I was trying all this stuff today in response to a customer issue

• With the exception of Safari configured for Japanese, all browsers our customer tested worked best with filename=text.pdf - where text is a customer value serialized by ASP.Net/IIS in utf-8 without url encoding. For some reason, Safari configured for English would accept and properly save a file with utf-8 Japanese name but that same browser configured for Japanese would save the file with the utf-8 chars uninterpreted. All other browsers tested seemed to work best/fine (regardless of language configuration) with the filename utf-8 encoded without url encoding.
• I could not find a single browser implementing Rfc5987/8187 at all. I tested with the latest Chrome, Firefox builds plus IE 11 and Edge. I tried setting the header with just filename*=utf-8''texturlencoded.pdf, setting it with both filename=text.pdf; filename*=utf-8''texturlencoded.pdf. Not one feature of Rfc5987/8187 appeared to be getting processed correctly in any of the above.

The best and most intuitive way is to use serialEvent() callback Arduino defines along with loop() and setup().

I've built a small library a while back that handles message reception, but never had time to opensource it. This library receives \n terminated lines that represent a command and arbitrary payload, space-separated. You can tweak it to use your own protocol easily.

First of all, a library, SerialReciever.h:

#ifndef __SERIAL_RECEIVER_H__
#define __SERIAL_RECEIVER_H__
    
class IncomingCommand {
  private:
    static boolean hasPayload;
  public:
    static String command;
    static String payload;
    static boolean isReady;
    static void reset() {
      isReady = false;
      hasPayload = false;
      command = "";
      payload = "";
    }
    static boolean append(char c) {
      if (c == '\n') {
        isReady = true;
        return true;
      }
      if (c == ' ' && !hasPayload) {
        hasPayload = true;
        return false;
      }
      if (hasPayload)
        payload += c;
      else
        command += c;
      return false;
    }
};
    
boolean IncomingCommand::isReady = false;
boolean IncomingCommand::hasPayload = false;
String IncomingCommand::command = false;
String IncomingCommand::payload = false;
    
#endif // #ifndef __SERIAL_RECEIVER_H__

To use it, in your project do this:

#include <SerialReceiver.h>
    
void setup() {
  Serial.begin(115200);
  IncomingCommand::reset();
}
    
void serialEvent() {
  while (Serial.available()) {
    char inChar = (char)Serial.read();
    if (IncomingCommand::append(inChar))
      return;
  }
}

To use the received commands:

void loop() {
  if (!IncomingCommand::isReady) {
    delay(10);
    return;
  }

executeCommand(IncomingCommand::command, IncomingCommand::payload); // I use registry pattern to handle commands, but you are free to do whatever suits your project better.
    
IncomingCommand::reset();

From the Java interface design FAQ by Philip Shaw:

Interface variables are static because Java interfaces cannot be instantiated in their own right; the value of the variable must be assigned in a static context in which no instance exists. The final modifier ensures the value assigned to the interface variable is a true constant that cannot be re-assigned by program code.

Look at the following:

echo "ls -l" | at 07:00

This code line executes "ls -l" at a specific time. This is an example of executing something (a command in my example) at a specific time. "at" is the command you were really looking for. You can read the specifications here:

Hope it helps!

Below Kotlin code will help

Bottom to Top or Slide to Up

private fun slideUp() {
    isMapInfoShown = true
    views!!.layoutMapInfo.visible()
    val animate = TranslateAnimation(
        0f,  // fromXDelta
        0f,  // toXDelta
        views!!.layoutMapInfo.height.toFloat(),  // fromYDelta
        0f  // toYDelta
    )

    animate.duration = 500
    animate.fillAfter = true
    views!!.layoutMapInfo.startAnimation(animate)
}

Top to Bottom or Slide to Down

private fun slideDown() {
    if (isMapInfoShown) {
        isMapInfoShown = false
        val animate = TranslateAnimation(
            0f,  // fromXDelta
            0f,  // toXDelta
            0f,  // fromYDelta
            views!!.layoutMapInfo.height.toFloat()  // toYDelta
        )

        animate.duration = 500
        animate.fillAfter = true
        views!!.layoutMapInfo.startAnimation(animate)
        views!!.layoutMapInfo.gone()
    }
}

Kotlin Extensions for Visible and Gone

fun View.visible() {
    this.visibility = View.VISIBLE
}


fun View.gone() {
    this.visibility = View.GONE
}

Instead of using long command like

php artisan make:model <Model Name> --migration --controller --resource

for make migration, model and controller, you may use even shorter as -mcr.

php artisan make:model <Model Name> -mcr

You may use closest() in modern browsers:

var div = document.querySelector('div#myDiv');
div.closest('div[someAtrr]');

Use object detection to supply a polyfill or alternative method for backwards compatability with IE.

As far as i know %d means decadic which is number without decimal point. if you want to load double value, use %lf conversion (long float). for printf your values are wrong for same reason, %d is used only for integer (and possibly chars if you know what you are doing) numbers.

Example:

double a,b;
printf("--------\n"); //seperate lines
scanf("%lf",&a);
printf("--------\n"); 
scanf("%lf",&b);
printf("%lf %lf",a,b);

I split it into separate lines to make it a little more readable.

Feel free to browse the Lua Wiki on table serialization. It lists several ways on how to dump a table to the console.

You just have to choose which one suits you best. There are many ways to do it, but I usually end up using the one from Penlight:

> t = { a = { b = { c = "Hello world!", 1 }, 2, d = { 3 } } }
> require 'pl.pretty'.dump(t)
{
  a = {
    d = {
      3
    },
    b = {
      c = "Hello world!",
      1
    },
    2
  }
}

In simple terms you need to build your payload into a key array

payload = {'key1': 'value1', 'key2': 'value2'}

Then send the payload directly to the action

this.$store.dispatch('yourAction', payload)

No change in your action

yourAction: ({commit}, payload) => {
  commit('YOUR_MUTATION',  payload )
},

In your mutation call the values with the key

'YOUR_MUTATION' (state,  payload ){
  state.state1 = payload.key1
  state.state2 =  payload.key2
},

<img id="uxcMyImageId" src"myImage" width="100" height="100" />

specifying width and height in the image tag is a good practice..this way when the page loads there is space allocated for the image and the layout does not suffer any jerks even if the image takes a long time to load.

The standard approach is to give the centered element fixed dimensions, and place it absolutely:

<div class='fullscreenDiv'>
    <div class="center">Hello World</div>
</div>?

.center {
    position: absolute;
    width: 100px;
    height: 50px;
    top: 50%;
    left: 50%;
    margin-left: -50px; /* margin is -0.5 * dimension */
    margin-top: -25px; 
}?

The above answers summarize the role of getters and setters better than I could, however I did want to add that your code should ideally be structured to reduce the use of pure getters and setters, i.e. those without complex constructions, validation, and so forth, as they break encapsulation. This doesn't mean you can't ever use them (stivlo's answer shows an example of a good use of getters and setters), just try to minimize how often you use them.

The problem is that getters and setters can act as a workaround for direct access of private data. Private data is called private because it's not meant to be shared with other objects; it's meant as a representation of the object's state. Allowing other objects to access an object's private fields defeats the entire purpose of setting it private in the first place. Moreover, you introduce coupling for every getter or setter you write. Consider this, for example:

private String foo;

public void setFoo(String bar) {
    this.foo = bar;
}

What happens if, somewhere down the road, you decide you don't need foo anymore, or you want to make it an integer? Every object that uses the setFoo method now needs to be changed along with foo.

#!/bin/bash

msg1=${1} #First Parameter
msg2=${2} #Second Parameter

concatString=$msg1"$msg2" #Concatenated String
concatString2="$msg1$msg2"

echo $concatString 
echo $concatString2

CORRECTION: Please vote for Peter Štibraný's answer - it is more correct and complete!

A "JSESSIONID" is the unique id of the http session - see the javadoc here. There, you'll find the following sentence

Session information is scoped only to the current web application (ServletContext), so information stored in one context will not be directly visible in another.

So when you first hit a site, a new session is created and bound to the SevletContext. If you deploy multiple applications, the session is not shared.

You can also invalidate the current session and therefore create a new one. e.g. when switching from http to https (after login), it is a very good idea, to create a new session.

Hope, this answers your question.

This is something of a religious debate. Both approaches have their problems.

• Use instanceof and you can never add significant members to subclasses.
• Use getClass and you violate the Liskov substitution principle.

Bloch has another relevant piece of advice in Effective Java Second Edition:

• Item 17: Design and document for inheritance or prohibit it

In git stash is a storage area where current changed files can be moved.

stash area is useful when you want to pull some changes from git repository and detected some changes in some mutual files available in git repo.

git stash apply //apply the changes without removing stored files from stash area.

git stash pop  // apply the changes as well as remove stored files from stash area.

Note :- git apply only apply the changes from stash area while git pop apply as well as remove change from stash area.

You can very easily create an EXE (for Windows) without using any cryptic build commands. You can do it right in Visual Studio.

1. Right click the Console App Project and select Publish.
2. A new page will open up (screen shot below)
3. Hit Configure...
4. Then change Deployment Mode to Self-contained or Framework dependent. .NET Core 3.0 introduces a Single file deployment which is a single executable.
5. Use "framework dependent" if you know the target machine has a .NET Core runtime as it will produce fewer files to install.
6. If you now view the bin folder in explorer, you will find the .exe file.
7. You will have to deploy the exe along with any supporting config and dll files.
