An easy solution is to rename all non-index.php files to .inc, then deny access to *.inc files. I use this in a lot of my projects and it works perfectly fine.

Swift 3, with extension:

extension UIView{
    var globalPoint :CGPoint? {
        return self.superview?.convert(self.frame.origin, to: nil)
    }

    var globalFrame :CGRect? {
        return self.superview?.convert(self.frame, to: nil)
    }
}

In the off chance that someone finds themselves beating their head against the wall trying to figure out why a coworker's script won't print newlines, look out for this ->

#!/bin/bash
function GET_RECORDS()
{
   echo -e "starting\n the process";
}

echo $(GET_RECORDS);

As in the above, the actual running of the method may itself be wrapped in an echo which supersedes any echos that may be in the method itself. Obviously I watered this down for brevity, it was not so easy to spot!

You can then inform your comrades that a better way to execute functions would be like so:

#!/bin/bash
function GET_RECORDS()
{
   echo -e "starting\n the process";
}

GET_RECORDS;

in my case, I need to have my wcf running for more than 2 hours. Setting and did not work at all. The wcf did not execute longer than maybe 20~30 minutes. So I changed the idle timeout setting of application pool in IIS manager then it worked! In IIS manager, choose your application pool and right click on it and choose advanced settings then change the idle timeout setting to any minutes you want. So, I think setting the web.config and setting the application pool are both needed.

For completing the answers, Spring MVC uses viewResolver(for example, as axtavt metionned, InternalResourceViewResolver) to get the specific view. Therefore the first step is making sure that a viewResolver is configured.

Secondly, you should pay attention to the url of redirection(redirect or forward). A url starting with "/" means that it's a url absolute in the application. As Jigar says,

return "redirect:/index.html";  

should work. If your view locates in the root of the application, Spring can find it. If a url without a "/", such as that in your question, it means a url relative. It explains why it worked before and don't work now. If your page calling "redirect" locates in the root by chance, it works. If not, Spring can't find the view and it doesn't work.

Here is the source code of the method of RedirectView of Spring

protected void renderMergedOutputModel(  
Map<String, Object> model, HttpServletRequest request, HttpServletResponse response)  
throws IOException {  
  // Prepare target URL.  
  StringBuilder targetUrl = new StringBuilder();  
  if (this.contextRelative && getUrl().startsWith("/")) {  
    // Do not apply context path to relative URLs.  
    targetUrl.append(request.getContextPath());  
  }  
  targetUrl.append(getUrl());  

  // ...  

  sendRedirect(request, response, targetUrl.toString(), this.http10Compatible);  
}  

string Output = Regex.Replace(Input, @"([ a-zA-Z0-9&, _]|^\s)", "");

Here all the special characters except space, comma, and ampersand are replaced. You can also omit space, comma and ampersand by the following regular expression.

string Output = Regex.Replace(Input, @"([ a-zA-Z0-9_]|^\s)", "");

Where Input is the string which we need to replace the characters.

Another option is to use a destination wildcard. Note that this only works if the source and destination filenames will be the same, so while this doesn't solve the OP's specific example, I thought it was worth sharing.

For example:

xcopy /y "bin\development\whee.config.example" "TestConnectionExternal\bin\Debug\*" 

will create a copy of the file "whee.config.example" in the destination directory without prompting for file or directory.

Update: As mentioned by @chapluck:

You can change "* " to "[newFileName].*". It persists file extension but allows to rename. Or more hacky: "[newFileName].[newExt]*" to change extension

In swift 4.2 I used following code to show and hide code using NSNotification

 @objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo? [UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        let keyboardheight = keyboardSize.height
        print(keyboardheight)
    }

When you are using Multiple css property with jQuery then you must use the curly Brace in starting and in the end. You are missing the ending curly brace.

function init() {
 $("h1").css("backgroundColor", "yellow");

 $("#myParagraph").css({"background-color":"black","color":"white"});

 $(".bordered").css("border", "1px solid black");
}

You can have a look at this jQuery CSS Selector tutorial.

You can change the value of a bool all you want. As for an if:

if randombool == True:

works, but you can also use:

if randombool:

If you want to test whether something is false you can use:

if randombool == False

but you can also use:

if not randombool:

Ok, so this was a bit harder than I though:

def print_matrix(list_of_list):
    number_width = len(str(max([max(i) for i in list_of_list])))
    cols = max(map(len, list_of_list))
    output = '+'+('-'*(number_width+2)+'+')*cols + '\n'
    for row in list_of_list:
        for column in row:
            output += '|' + ' {:^{width}d} '.format(column, width = number_width)
        output+='|\n+'+('-'*(number_width+2)+'+')*cols + '\n'
    return output

This should work for variable number of rows, columns and number of digits (for numbers)

data = [[1,2,30],
        [4,23125,6],
        [7,8,999],
        ]
print print_matrix(data)

String pooling

String pooling (sometimes also called as string canonicalisation) is a process of replacing several String objects with equal value but different identity with a single shared String object. You can achieve this goal by keeping your own Map (with possibly soft or weak references depending on your requirements) and using map values as canonicalised values. Or you can use String.intern() method which is provided to you by JDK.

At times of Java 6 using String.intern() was forbidden by many standards due to a high possibility to get an OutOfMemoryException if pooling went out of control. Oracle Java 7 implementation of string pooling was changed considerably. You can look for details in http://bugs.sun.com/view_bug.do?bug_id=6962931 and http://bugs.sun.com/view_bug.do?bug_id=6962930.

String.intern() in Java 6

In those good old days all interned strings were stored in the PermGen – the fixed size part of heap mainly used for storing loaded classes and string pool. Besides explicitly interned strings, PermGen string pool also contained all literal strings earlier used in your program (the important word here is used – if a class or method was never loaded/called, any constants defined in it will not be loaded).

The biggest issue with such string pool in Java 6 was its location – the PermGen. PermGen has a fixed size and can not be expanded at runtime. You can set it using -XX:MaxPermSize=96m option. As far as I know, the default PermGen size varies between 32M and 96M depending on the platform. You can increase its size, but its size will still be fixed. Such limitation required very careful usage of String.intern – you’d better not intern any uncontrolled user input using this method. That’s why string pooling at times of Java 6 was mostly implemented in the manually managed maps.

String.intern() in Java 7

Oracle engineers made an extremely important change to the string pooling logic in Java 7 – the string pool was relocated to the heap. It means that you are no longer limited by a separate fixed size memory area. All strings are now located in the heap, as most of other ordinary objects, which allows you to manage only the heap size while tuning your application. Technically, this alone could be a sufficient reason to reconsider using String.intern() in your Java 7 programs. But there are other reasons.

String pool values are garbage collected

Yes, all strings in the JVM string pool are eligible for garbage collection if there are no references to them from your program roots. It applies to all discussed versions of Java. It means that if your interned string went out of scope and there are no other references to it – it will be garbage collected from the JVM string pool.

Being eligible for garbage collection and residing in the heap, a JVM string pool seems to be a right place for all your strings, isn’t it? In theory it is true – non-used strings will be garbage collected from the pool, used strings will allow you to save memory in case then you get an equal string from the input. Seems to be a perfect memory saving strategy? Nearly so. You must know how the string pool is implemented before making any decisions.

After going over some of the answers here an in another thread, here's what I ended up with:

I created a function named showAlert() that would dynamically add an alert, with an optional type and closeDealy. So that you can, for example, add an alert of type danger (i.e., Bootstrap's alert-danger) that will close automatically after 5 seconds like so:

showAlert("Warning message", "danger", 5000);

To achieve that, add the following Javascript function:

function showAlert(message, type, closeDelay) {

    if ($("#alerts-container").length == 0) {
        // alerts-container does not exist, add it
        $("body")
            .append( $('<div id="alerts-container" style="position: fixed;
                width: 50%; left: 25%; top: 10%;">') );
    }

    // default to alert-info; other options include success, warning, danger
    type = type || "info";    

    // create the alert div
    var alert = $('<div class="alert alert-' + type + ' fade in">')
        .append(
            $('<button type="button" class="close" data-dismiss="alert">')
            .append("&times;")
        )
        .append(message);

    // add the alert div to top of alerts-container, use append() to add to bottom
    $("#alerts-container").prepend(alert);

    // if closeDelay was passed - set a timeout to close the alert
    if (closeDelay)
        window.setTimeout(function() { alert.alert("close") }, closeDelay);     
}

Having the same error trying to install matplotlib for Python 3, those solutions didn't work for me. It was just a matter of dependencies, though it wasn't clear in the error message.

I used sudo apt-get build-dep python3-matplotlib then sudo pip3 install matplotlib and it worked.

Hope it'll help !

Or you could keep it simple by doing something like this:

alert(angular.equals({}, $scope.items));

In laravel 7, to set current time use following:

$table->timestamp('column_name')->useCurrent();

It is possible to play a local video file.

<input type="file" accept="video/*"/>
<video controls autoplay></video>

When a file is selected via the input element:

1. 'change' event is fired
2. Get the first File object from the input.files FileList
3. Make an object URL that points to the File object
4. Set the object URL to the video.src property

5. Lean back and watch :)

You can Use below code to call the web service and get response .Make sure that your Web Service return the response in Data Table Format..This code help you if you using data from SQL Server database .If you you using MYSQL you need to change one thing just replace word NewDataSet from sentence obj2=(SoapObject) obj1.getProperty("NewDataSet"); by DocumentElement

private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://localhost/Web_Service.asmx?"; // you can use   IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = NAMESPACE + METHOD_NAME;

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("parm_name", prm_value); // Parameter for Method
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

try {
    androidHttpTransport.call(SOAP_ACTION, envelope); //call the eb service Method
} catch (Exception e) {
    e.printStackTrace();
} //Next task is to get Response and format that response

SoapObject obj, obj1, obj2, obj3;
obj = (SoapObject) envelope.getResponse();
obj1 = (SoapObject) obj.getProperty("diffgram");
obj2 = (SoapObject) obj1.getProperty("NewDataSet");

for (int i = 0; i < obj2.getPropertyCount(); i++) //the method getPropertyCount() return the number of rows
{
    obj3 = (SoapObject) obj2.getProperty(i);
    obj3.getProperty(0).toString(); //value of column 1
    obj3.getProperty(1).toString(); //value of column 2
    //like that you will get value from each column
}

If you have any problem regarding this you can write me..

If I understand correctly you may be experiencing the problem because in order to be able to set the labels "text" property you actually have to use the "content" property.

so instead of:

  Label output = null;
        output = Label1;
        output.Text = "hello";

try:

Label output = null;
            output = Label1;
            output.Content = "hello";

For getting the practical view of converting .apk file into .java files just check out https://www.youtube.com/watch?v=-AX4NYE-9V8 video . you will get more benefited and understand clearly. It clearly demonstrates the steps you required if you are using mac OS.

For those who can't (or don't want to) setup a debugger to track down the original exception which was causing the rollback-flag to get set, you can just add a bunch of debug statements throughout your code to find the lines of code which trigger the rollback-only flag:

logger.debug("Is rollbackOnly: " + TransactionAspectSupport.currentTransactionStatus().isRollbackOnly());

Adding this throughout the code allowed me to narrow down the root cause, by numbering the debug statements and looking to see where the above method goes from returning "false" to "true".

Type-Safe is code that accesses only the memory locations it is authorized to access, and only in well-defined, allowable ways. Type-safe code cannot perform an operation on an object that is invalid for that object. The C# and VB.NET language compilers always produce type-safe code, which is verified to be type-safe during JIT compilation.

In plain JS add { passive: false } as third argument

document.addEventListener('wheel', function(e) {
    e.preventDefault();
    doStuff(e);
}, { passive: false });

I don't know that you can do it in Chrome outside of Windows -- some Googling shows that Chrome (and therefore possibly Chromium) might respond well to a certain registry hack.

However, if you're just looking for a simple solution without modifying your code base, have you considered Firefox? In the about:config you can search for "network.http.max" and there are a few values in there that are definitely worth looking at.

Also, for a device that will not be moving (i.e. it is mounted in a fixed location) you should consider not using Wi-Fi (even a Home-Plug would be a step up as far as latency / stability / dropped connections go).

You can use jQuery's Deferred object along with the when method.

deferredArray = [];
forloop {
    deferred = new $.Deferred();
    ajaxCall(function() {
      deferred.resolve();
    }
    deferredArray.push(deferred);
}

$.when(deferredArray, function() {
  //this code is called after all the ajax calls are done
});

var streetaddress= addy.substr(0, addy.indexOf(',')); 

While it's not the best place for definitive information on what each method does (mozilla developer network is better for that) w3schools.com is good for introducing you to syntax.

1) on your mac type

nano /usr/bin/wget

2) paste the following in

#!/bin/bash
curl -L $1 -o $2

3) close then make it executable

chmod 777 /usr/bin/wget

That's it.

With ASP.net Web API 2 install Microsoft ASP.NET Cross Origin support via nuget.

http://enable-cors.org/server_aspnet.html

public static void Register(HttpConfiguration config)

 var enableCorsAttribute = new EnableCorsAttribute("http://mydomain.com",
                                                   "Origin, Content-Type, Accept",
                                                   "GET, PUT, POST, DELETE, OPTIONS");
        config.EnableCors(enableCorsAttribute);

Your form method is post. So open the Middleware/VerifyCsrfToken .php file , find the isReading() method and add 'POST' method in array.

Try it. You can get Device Name through Bluetooth.

Hope it will help you

public String getPhoneName() {  
        BluetoothAdapter myDevice = BluetoothAdapter.getDefaultAdapter();
        String deviceName = myDevice.getName();     
        return deviceName;
    }

I believe you'd want to escape by doubling the single quote:

INSERT INTO table_name (field1, field2) VALUES (123, 'Hello there''s');

onCreate(Bundle) is called when the activity first starts up. You can use it to perform one-time initialization such as creating the user interface. onCreate() takes one parameter that is either null or some state information previously saved by the onSaveInstanceState.

with jQuery :
html :

<form method="POST" name="myform" action="index.php?action=contact_agent&agent_id="  onsubmit="SetData()">
  <select name="agent" id="agent">
    <option value="1">Agent Homer</option>
    <option value="2">Agent Lenny</option>
    <option value="3">Agent Carl</option>
  </select>
</form>

jQuery :

$('form').submit(function(){
   $(this).attr('action',$(this).attr('action')+$('#agent').val());
   $(this).submit();
});

javascript :

function SetData(){
   var select = document.getElementById('agent');
   var agent_id = select.options[select.selectedIndex].value;
   document.myform.action = "index.php?action=contact_agent&agent_id="+agent_id ; # or .getAttribute('action')
   myform.submit();
}

Here is an example that I used.

<script>
  $(document).ready(function(){
      var array =  $.makeArray(document.getElementsByTagName(“p”));
      array.reverse(); 
      $(array).appendTo(document.body);
  });
</script>

You might be better off using the Properties Service as you can use these as a kind of persistent global variable.

click 'file > project properties > project properties' to set a key value, or you can use

PropertiesService.getScriptProperties().setProperty('mykey', 'myvalue');

The data can be retrieved with

var myvalue = PropertiesService.getScriptProperties().getProperty('mykey');

In simple terms, Java supports the declaration of a class to be static only for the inner classes but not for the top level classes.

top level classes: A java project can contain more than one top level classes in each java source file, one of the classes being named after the file name. There are only three options or keywords allowed in front of the top level classes, public, abstract and final.

Inner classes: classes that are inside of a top level class are called inner classes, which is basically the concept of nested classes. Inner classes can be static. The idea making the inner classes static, is to take the advantage of instantiating the objects of inner classes without instantiating the object of the top level class. This is exactly the same way as the static methods and variables work inside of a top level class.

Hence Java Supports Static Classes at Inner Class Level (in nested classes)

And Java Does Not Support Static Classes at Top Level Classes.

I hope this gives a simpler solution to the question for basic understanding of the static classes in Java.

Here is an example of what I would do. I hope it's what you're looking for.

char_array = c("foo_bar","bar_foo","apple","beer")
a = data.frame("data"=char_array,"data2"=1:4)
a$data = substr(a$data,1,nchar(a$data)-3)

a should now contain:

  data data2
1 foo_ 1
2 bar_ 2
3   ap 3
4    b 4

Doing this asynchronously is quite easy. It's particularly useful if you're concerned for blocking the thread (likely).

const fs = require('fs');
const fileName = './file.json';
const file = require(fileName);
    
file.key = "new value";
    
fs.writeFile(fileName, JSON.stringify(file), function writeJSON(err) {
  if (err) return console.log(err);
  console.log(JSON.stringify(file));
  console.log('writing to ' + fileName);
});

The caveat is that json is written to the file on one line and not prettified. ex:

{
  "key": "value"
}

will be...

{"key": "value"}

To avoid this, simply add these two extra arguments to JSON.stringify

JSON.stringify(file, null, 2)

null - represents the replacer function. (in this case we don't want to alter the process)

2 - represents the spaces to indent.

Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text. Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 00. You may find the problem this way, providing there isn't masses of code.

Download the Hex Plugin from here; http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/

This problem can occur when you reference your web.config (or app.config) connection strings by index...

var con = ConfigurationManager.ConnectionStrings[0].ConnectionString;

The zero based connection string is not always the one in your config file as it inherits others by default from further up the stack.

The recommended approaches are to access your connection by name...

var con = ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString;

or to clear the connnectionStrings element in your config file first...

<connectionStrings>
    <clear/>
    <add name="MyConnection" connectionString="...

I had similar problem. I was using Android's DefaultHttpClient. I have read that HttpsURLConnection can handle this kind of exception. So I created custom HostnameVerifier which uses the verifier from HttpsURLConnection. I also wrapped the implementation to custom HttpClient.

public class CustomHttpClient extends DefaultHttpClient {

public CustomHttpClient() {
    super();
    SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory();
    socketFactory.setHostnameVerifier(new CustomHostnameVerifier());
    Scheme scheme = (new Scheme("https", socketFactory, 443));
    getConnectionManager().getSchemeRegistry().register(scheme);
}

Here is the CustomHostnameVerifier class:

public class CustomHostnameVerifier implements org.apache.http.conn.ssl.X509HostnameVerifier {

@Override
public boolean verify(String host, SSLSession session) {
    HostnameVerifier hv = HttpsURLConnection.getDefaultHostnameVerifier();
    return hv.verify(host, session);
}

@Override
public void verify(String host, SSLSocket ssl) throws IOException {
}

@Override
public void verify(String host, X509Certificate cert) throws SSLException {

}

@Override
public void verify(String host, String[] cns, String[] subjectAlts) throws SSLException {

}

}

Headers included with #include <> will be searched in all default directories , but you can also add your own location in the search path with -I command line arg.

I saw your edit you could install your headers in default locations usually

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

Confirm with compiler docs though.

Try:

move "C:\files\*.txt" "C:\txt"

For this kind of question I think you have to be very specific about what you are looking for, as there are many ways of interpreting it and many different approaches. Some approaches are going to be too big a hammer if your question does not warrant it.

At the simplest level, there is "Is the table data exactly the same or not?", which you might attempt to answer with a simple count comparison before moving on to anything more complex.

At the other end of the scale there is "show me the rows from each table for which there is not an equivalent row in the other table" or "show me where rows have the same identifying key but different data values".

If you actually want to sync Table A with Table B then that might be relatively straightforward, using a MERGE command.

Without VBA...

If you can use a helper column, you can use the MATCH function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match

To simply identify duplicates, use a helper column

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")

Drag/copy this forumla down, and it should identify the duplicates.

To highlight cells, use conditional formatting:

With some tinkering, you can use this MATCH function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.

Something like:

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:

=B1="Duplicate"

This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

To those that are incline to use GUI:

Click Right mouse button on procecdure name then select Test

Then in new window you will see script generated just add the parameters and click on Start Debugger or F9

Hope this saves you some time.

Doom Emacs users, I hope you've scrolled this far or searched for 'doom' on the page...

• Doom Emacs breaks the vanilla Emacs redo shortcut: C-g C-/ C-/ C-/ etc (or C-g C-_ C-_ C-_ etc) ...and instead that just keeps undoing.
• Doom Emacs also breaks the undo-tree redo shortcut mentioned in one of the other answers as being useful for spacemacs etc: S-C-/ (AKA C-?) ...and instead that throws the error "C-? is not defined".

What you need is:

• to be in evil-mode (C-z to toggle in and out of evil-mode) (in evil-mode should see blue cursor, not orange cursor) and
• to be in 'command mode' AKA 'normal mode' (as opposed to 'insert mode') (Esc to switch to command mode) (should see block cursor, not line cursor), and then it's
• u for undo and
• C-r for redo

You can copy all contents of myhtml to String as follows:

Scanner myScanner = null;
try
{
    myScanner = new Scanner(myhtml);
    String contents = myScanner.useDelimiter("\\Z").next(); 
}
finally
{
    if(myScanner != null)
    {
        myScanner.close(); 
    }
}

Ofcourse, you can add a catch block to handle exceptions properly.

Yes, use gzip for this. The best way is to read data as input and redirect the compressed to output file i.e.

cat test.csv | gzip > test.csv.gz

cat test.csv will send the data as stdout and using pipe-sign gzip will read that data as stdin. Make sure to redirect the gzip output to some file as compressed data will not be written to the terminal.

Small reusable method can be written for creating person json object to avoid duplicate code

JSONObject  getPerson(String firstName, String lastName){
   JSONObject person = new JSONObject();
   person .put("firstName", firstName);
   person .put("lastName", lastName);
   return person ;
} 

public JSONObject getJsonResponse(){

    JSONArray employees = new JSONArray();
    employees.put(getPerson("John","Doe"));
    employees.put(getPerson("Anna","Smith"));
    employees.put(getPerson("Peter","Jones"));

    JSONArray managers = new JSONArray();
    managers.put(getPerson("John","Doe"));
    managers.put(getPerson("Anna","Smith"));

Kotlin Reusable Extension Solution

Simplify removal

Add this extension:

myView.removeSelf()

fun View?.removeSelf() {
    this ?: return
    val parent = parent as? ViewGroup ?: return
    parent.removeView(this)
}

Simplify addition

Here are a few options:

// Built-in
myViewGroup.addView(myView)

// Null-safe extension
fun ViewGroup?.addView(view: View?) {
    this ?: return
    view ?: return
    addView(view)
}

// Reverse addition
myView.addTo(myViewGroup)

fun View?.addTo(parent: ViewGroup?) {
    this ?: return
    parent ?: return
    parent.addView(this)
}

Great references on lists and css here:

http://alistapart.com/article/taminglists/

here's one i just wrote, maybe it's not as optimized (just uses a sorted dictionary) but simple to understand. you can insert objects of different kinds, so no generic queues.

using System;
using System.Diagnostics;
using System.Collections;
using System.Collections.Generic;

namespace PrioQueue
{
    public class PrioQueue
    {
        int total_size;
        SortedDictionary<int, Queue> storage;

        public PrioQueue ()
        {
            this.storage = new SortedDictionary<int, Queue> ();
            this.total_size = 0;
        }

        public bool IsEmpty ()
        {
            return (total_size == 0);
        }

        public object Dequeue ()
        {
            if (IsEmpty ()) {
                throw new Exception ("Please check that priorityQueue is not empty before dequeing");
            } else
                foreach (Queue q in storage.Values) {
                    // we use a sorted dictionary
                    if (q.Count > 0) {
                        total_size--;
                        return q.Dequeue ();
                    }
                }

                Debug.Assert(false,"not supposed to reach here. problem with changing total_size");

                return null; // not supposed to reach here.
        }

        // same as above, except for peek.

        public object Peek ()
        {
            if (IsEmpty ())
                throw new Exception ("Please check that priorityQueue is not empty before peeking");
            else
                foreach (Queue q in storage.Values) {
                    if (q.Count > 0)
                        return q.Peek ();
                }

                Debug.Assert(false,"not supposed to reach here. problem with changing total_size");

                return null; // not supposed to reach here.
        }

        public object Dequeue (int prio)
        {
            total_size--;
            return storage[prio].Dequeue ();
        }

        public void Enqueue (object item, int prio)
        {
            if (!storage.ContainsKey (prio)) {
                storage.Add (prio, new Queue ());
              }
            storage[prio].Enqueue (item);
            total_size++;

        }
    }
}

You could retrieve the body text of the whole page like this:

bodyText = self.driver.find_element_by_tag_name('body').text

then use an assert to check it like this:

self.assertTrue("the text you want to check for" in bodyText)

Of course, you can be specific and retrieve a specific DOM element's text and then check that instead of retrieving the whole page.

If the resource is showing and is a view, you can also capture it. Like a screenshot:

View rootView = ((View) findViewById(R.id.yourView)).getRootView();
rootView.setDrawingCacheEnabled(true);
rootView.layout(0, 0, rootView.getWidth(), rootView.getHeight());
rootView.buildDrawingCache();

Bitmap bm = Bitmap.createBitmap(rootView.getDrawingCache());

rootView.setDrawingCacheEnabled(false);

This actually grabs the whole layout but you can alter as you wish.

http://www.rtuin.nl/2013/02/how-to-make-git-ignore-different-line-endings/

echo "* -crlf" > .gitattributes 

Do this on a separate commit or git might still see whole files as modified when you make a single change (depending on if you have changed autocrlf option)

This one really works. Git will respect the line endings in mixed line ending projects and not warning you about them.

I didn't know you could do that with cp.

You can do it with mkdir ..

mkdir -p /var/path/to/your/dir

EDIT See lhunath's answer for incorporating cp.

After some frustration I tried the following which worked for me:

Convert cells to date format if not already done. Go to the Data tab and click sort. Click sort after choosing expand selection or continue with current selection. Sort by Date Sort on Values order Z to A for newest date first. Click OK. Choose "Sort anything that looks like a number, as a number".

Simply, change

<textarea rows="15" cols="50" id="aboutDescription"
style="resize: none;"></textarea>

to

<textarea rows="15" cols="50" id="aboutDescription"
style="resize: none;" data-role="none"></textarea>

ie, add:

data-role="none"

You can also by jquery:

$('#foo')[0].disabled = true;

Working example:

$('#foo')[0].disabled = true;

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<input id="foo" placeholder="placeholder" value="value" />

If the input value gets populated by a script that has some latency involved (e.g. AJAX call) then you need to wait until the input has been populated. E.g.

var w = new WebDriverWait(WebBrowser, TimeSpan.FromSeconds(10));
            w.Until((d) => {
                // Wait until the input has a value...

                var elements = d.FindElements(By.Name(name));

                var ele = elements.SingleOrDefault();

                if (ele != null)
                {
                    // Found a single element

                    if (ele.GetAttribute("value") != "")
                    {
                        // We have a value now
                        return true;
                    }
                }

                return false;
                });

        var e = WebBrowser.Current.FindElement(By.Name(name));

        if (e.GetAttribute("value") != value)
        {
            Assert.Fail("Result contains a field named '{0}', but its value is '{1}', not '{2}' as expected", name, e.GetAttribute("value"), value);
        }

You can use Scanner class

Import first :

import java.util.Scanner;

Then you use like this.

Scanner keyboard = new Scanner(System.in);
System.out.println("enter an integer");
int myint = keyboard.nextInt();

Side note : If you are using nextInt() with nextLine() you probably could have some trouble cause nextInt() does not read the last newline character of input and so nextLine() then is not gonna to be executed with desired behaviour. Read more in how to solve it in this previous question Skipping nextLine using nextInt.

Use this to change the hint color. -

editText.setHintTextColor(getResources().getColor(R.color.white));

Solution for your problem -

editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2,int arg3){
        //do something
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        //do something
    }

    @Override
    public void afterTextChanged(Editable arg0) {
        if(arg0.toString().length() <= 0) //check if length is equal to zero
            tv.setHintTextColor(getResources().getColor(R.color.white));
    }
});

I wouldn't go with MSTest. Although it's probably the most future proof of the frameworks with Microsoft behind it's not the most flexible solution. It won't run stand alone without some hacks. So running it on a build server other than TFS without installing Visual Studio is hard. The visual studio test-runner is actually slower than Testdriven.Net + any of the other frameworks. And because the releases of this framework are tied to releases of Visual Studio there are less updates and if you have to work with an older VS you're tied to an older MSTest.

I don't think it matters a lot which of the other frameworks you use. It's really easy to switch from one to another.

I personally use XUnit.Net or NUnit depending on the preference of my coworkers. NUnit is the most standard. XUnit.Net is the leanest framework.

Kiss Jquery UI goodbye and a lightbox hello. You can get it here.

I would suggest using regexes:

var intRegex = /^\d+$/;
var floatRegex = /^((\d+(\.\d *)?)|((\d*\.)?\d+))$/;

var str = $('#myTextBox').val();
if(intRegex.test(str) || floatRegex.test(str)) {
   alert('I am a number');
   ...
}

Or with a single regex as per @Platinum Azure's suggestion:

var numberRegex = /^[+-]?\d+(\.\d+)?([eE][+-]?\d+)?$/;
var str = $('#myTextBox').val();
if(numberRegex.test(str)) {
   alert('I am a number');
   ...
}

I have a very easy solution

let x1,y1 x2,y2 ,l1,b1,l2,be cordinates and lengths and breadths of them respectively

consider the condition ((x2

now the only way these rectangle will overlap is if the point diagonal to x1,y1 will lie inside the other rectangle or similarly the point diagonal to x2,y2 will lie inside the other rectangle. which is exactly the above condition implies.

The error tells you that there is an error but you don´t catch it. This is how you can catch it:

getAllPosts().then(response => {
    console.log(response);
}).catch(e => {
    console.log(e);
});

You can also just put a console.log(reponse) at the beginning of your API callback function, there is definitely an error message from the Graph API in it.

More information: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch

Or with async/await:

//some async function
try {
    let response = await getAllPosts();
} catch(e) {
    console.log(e);
}

Carry Flag

The rules for turning on the carry flag in binary/integer math are two:

1. The carry flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. 1111 + 0001 = 0000 (carry flag is turned on)

2. The carry (borrow) flag is also set if the subtraction of two numbers requires a borrow into the most significant (leftmost) bits subtracted. 0000 - 0001 = 1111 (carry flag is turned on) Otherwise, the carry flag is turned off (zero).

   • 0111 + 0001 = 1000 (carry flag is turned off [zero])
   • 1000 - 0001 = 0111 (carry flag is turned off [zero])

In unsigned arithmetic, watch the carry flag to detect errors.

In signed arithmetic, the carry flag tells you nothing interesting.

Overflow Flag

The rules for turning on the overflow flag in binary/integer math are two:

1. If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)

2. If the sum of two numbers with the sign bits on yields a result number with the sign bit off, the "overflow" flag is turned on. 1000 + 1000 = 0000 (overflow flag is turned on)

Otherwise the "overflow" flag is turned off

• 0100 + 0001 = 0101 (overflow flag is turned off)
• 0110 + 1001 = 1111 (overflow flag turned off)
• 1000 + 0001 = 1001 (overflow flag turned off)
• 1100 + 1100 = 1000 (overflow flag is turned off)

Note that you only need to look at the sign bits (leftmost) of the three numbers to decide if the overflow flag is turned on or off.

If you are doing two's complement (signed) arithmetic, overflow flag on means the answer is wrong - you added two positive numbers and got a negative, or you added two negative numbers and got a positive.

If you are doing unsigned arithmetic, the overflow flag means nothing and should be ignored.

Go and look at the printf() implementation with "%f" in some C library.

You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.

1. Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.

2. In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)

3. You can format the x-axis options with this menu. (Chart->Design->Layout)

4. Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"

5. Set up the options you wish. (Fix the starting and ending points.)

6. And you will get a graph such as the one below.

You can then tweak many of the options, label the axes better etc, but this should get you started.

Hope this helps you move forward.

Well, initially, we should know what caused the error to happen, then the solution will be easy. The reason have already been pointed out by the accepted answer, but it is somehow incomplete (also the solution).

The problem is, one or more files had conflict(s) previously, but Git sees them as unresolved. Yes, you might already edited those files and resolved the conflicts, but Git does not know about that. You should tell Git "Hey, there are no more conflicts from the previous merge!". Note that, the merge is not necessarily caused by a git merge, but also by a git stash pop, for example.

Remember, git status can tell you what Git knows now. If there are some unresolved merge conflicts to Git, then it is shown in a separated Unmerged paths section, with the files marked as both modified (always?). If you have noticed, this section is between two staged and unstaged sections. From this, I personally understand that, "Unmerged paths are those you should either move into staged or unstaged areas, as Git can work only with these two areas".

So, to tell Git the conflicts have been resolved, you should either move these changes to staged or unstaged areas. In recent versions of Git, when you do a git status, it tells you how (woah! You should ask yourself how you haven't seen this yet?):

$ git status
...
Unmerged paths:
  (use "git restore --staged <file>..." to unstage)
  (use "git add <file>..." to mark resolution)
        both modified:   path/to/file.txt
...

So, to stage it (and maybe commit it):

$ git add path/to/file.txt

And to make it unstaged (e.g. you don't want to commit it now):

$ git restore --staged path/to/file.txt

Note: Forgetting to write --staged option possibly could spawn a super-hungry dragon to eat your past two days, in the case of not using a good text-editor or IDE.

Note: While git restore command is experimental yet, it should be stable enough to be used (thanks to a comment by @VonC, refer to it for more details on that).

You can simply do some kind of ajax response filter for incomming responses with $.ajaxSetup. If the response contains MVC redirection you can evaluate this expression on JS side. Example code for JS below:

$.ajaxSetup({
    dataFilter: function (data, type) {
        if (data && typeof data == "string") {
            if (data.indexOf('window.location') > -1) {
                eval(data);
            }
        }
        return data;
    }
});

If data is: "window.location = '/Acount/Login'" above filter will catch that and evaluate to make the redirection.

This post helped me today, but I had to experiment to do what I needed. Here is what I found.

Should you want to add more complex time periods, for example 1 year and 15 days, you can use

UPDATE tablename SET datefieldname = curdate() + INTERVAL 15 DAY + INTERVAL 1 YEAR;

I found that using DATE_ADD doesn't allow for adding more than one interval. And there is no YEAR_DAYS interval keyword, though there are others that combine time periods. If you are adding times, use now() rather than curdate().

Use attributed string:

// Define attributes
let labelFont = UIFont(name: "HelveticaNeue-Bold", size: 18)
let attributes :Dictionary = [NSFontAttributeName : labelFont]

// Create attributed string
var attrString = NSAttributedString(string: "Foo", attributes:attributes)
label.attributedText = attrString

You need to define attributes.

Using attributed string you can mix colors, sizes, fonts etc within one text

Beyond compare allows you to do that and much more.

It's one of those tools I can't live without.
Take a look here for a reference on the scripting options

I updated my project app/build.gradle to have

compileSDkVersion 26
buildToolsVersion '26.0.1'

However, the problem was actually with the react-native-fbsdk package. I had to change the same settings in node_modules/react-native-fbsdk/android/build.gradle.

For me, the mistake was forgetting to put FTP into binary mode before uploading the font files.

Edit

You can test for this by uploading other types of binary data like images. If they also fail to display, then this may be your issue.

The right way is this:

Integer i = Integer.class.cast(obj);

The method cast() is a much safer alternative to compile-time casting.

normaly is better image store in public folder (because it has write permission already that you can use when I upload images to it)

public
    upload_media
         photos
            image.png


$image  = public_path() . '/upload_media/photos/image.png'; // destination path

view PHP

<img src="<?= $image ?>">

View blade

<img src="{{ $image }}">

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

In Java 8 we have multiple ways to iterate over collection classes.

Using Iterable forEach

The collections that implement Iterable (for example all lists) now have forEach method. We can use method-reference introduced in Java 8.

Arrays.asList(1,2,3,4).forEach(System.out::println);

Using Streams forEach and forEachOrdered

We can also iterate over a list using Stream as:

Arrays.asList(1,2,3,4).stream().forEach(System.out::println);
Arrays.asList(1,2,3,4).stream().forEachOrdered(System.out::println);

We should prefer forEachOrdered over forEach because the behaviour of forEach is explicitly nondeterministic where as the forEachOrdered performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach does not guarantee that the order would be kept.

The advantage with streams is that we can also make use of parallel streams wherever appropriate. If the objective is only to print the items irrespective of the order then we can use parallel stream as:

Arrays.asList(1,2,3,4).parallelStream().forEach(System.out::println);

I think you can simply do:

class OuterClass:
    outer_var = 1

    class InnerClass:
        pass
    InnerClass.inner_var = outer_var

The problem you encountered is due to this:

A block is a piece of Python program text that is executed as a unit. The following are blocks: a module, a function body, and a class definition.
(...)
A scope defines the visibility of a name within a block.
(...)
The scope of names defined in a class block is limited to the class block; it does not extend to the code blocks of methods – this includes generator expressions since they are implemented using a function scope. This means that the following will fail:

   class A:  

       a = 42  

       b = list(a + i for i in range(10))

http://docs.python.org/reference/executionmodel.html#naming-and-binding

The above means:
a function body is a code block and a method is a function, then names defined out of the function body present in a class definition do not extend to the function body.

Paraphrasing this for your case:
a class definition is a code block, then names defined out of the inner class definition present in an outer class definition do not extend to the inner class definition.

Search and replace

:%s/search\|search2\|search3/replace/gci

g => global search

c => Ask for confirmation first

i => Case insensitive

If you want direct replacement without confirmation, use below command

:%s/search/replace/g

If you want confirmation for each replace then run the below command

:%s/search/replace/gc

Ask for confirmation first, here search will be case insensitive.

:%s/search/replace/gci

git log -1 branch_name will show you the last message from the specified branch (i.e. not necessarily the branch you're currently on).

First of all, before providing an answer I would like to be upfront about the fact that by trusting headers you are opening the door to security vulnerabilities such as phishing. So for redirection purposes, don't use values from headers without first validating the URL is authorized.

Then, your operating system hostname might not necessarily match the DNS one. In fact, one IP might have more than one DNS name. So for HTTP purposes there is no guarantee that the hostname assigned to your machine in your operating system configuration is useable.

The best choice I can think of is to obtain your HTTP listener public IP and resolve its name via DNS. See the dns.reverse method for more info. But then, again, note that an IP might have multiple names associated with it.

In Spring, bean scope is used to decide which type of bean instance should be returned from Spring container back to the caller.

5 types of bean scopes are supported :

1. Singleton : It returns a single bean instance per Spring IoC container.This single instance is stored in a cache of such singleton beans, and all subsequent requests and references for that named bean return the cached object.If no bean scope is specified in bean configuration file, default to singleton.

2. Prototype : It returns a new bean instance each time when requested. It does not store any cache version like singleton.

3. Request : It returns a single bean instance per HTTP request.

   

4. Session : It returns a single bean instance per HTTP session (User level session).

5. GlobalSession : It returns a single bean instance per global HTTP session. It is only valid in the context of a web-aware Spring ApplicationContext (Application level session).

In most cases, you may only deal with the Spring’s core scope – singleton and prototype, and the default scope is singleton.

^[^<>]+$

The caret in the character class ([^) means match anything but, so this means, beginning of string, then one or more of anything except < and >, then the end of the string.

Write bytes and Create the file if not exists:

f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()

wb means open the file in write binary mode.

Can't say I'm comfortable with any of the solutions based on exec. I prefer to use tee directly, so I make the script call itself with tee when requested:

# my script: 

check_tee_output()
{
    # copy (append) stdout and stderr to log file if TEE is unset or true
    if [[ -z $TEE || "$TEE" == true ]]; then 
        echo '-------------------------------------------' >> log.txt
        echo '***' $(date) $0 $@ >> log.txt
        TEE=false $0 $@ 2>&1 | tee --append log.txt
        exit $?
    fi 
}

check_tee_output $@

rest of my script

This allows you to do this:

your_script.sh args           # tee 
TEE=true your_script.sh args  # tee 
TEE=false your_script.sh args # don't tee
export TEE=false
your_script.sh args           # tee

You can customize this, e.g. make tee=false the default instead, make TEE hold the log file instead, etc. I guess this solution is similar to jbarlow's, but simpler, maybe mine has limitations that I have not come across yet.

Hi solution mentioned by Damien McGivern, Works on IIS6 only,

It does not work on IIS7 and ASP.NET Development Server. I get page displaying "404 - File or directory not found."

Any ideas?

EDIT:

Got it... This solution still doesn't work on ASP.NET Development Server, but I got the reason why it was not working on IIS7 in my case.

The reason is IIS7 has a built-in request scanning which imposes an upload file cap which defaults to 30000000 bytes (which is slightly less that 30MB).

And I was trying to upload file of size 100 MB to test the solution mentioned by Damien McGivern (with maxRequestLength="10240" i.e. 10MB in web.config). Now, If I upload the file of size > 10MB and < 30 MB then the page is redirected to the specified error page. But if the file size is > 30MB then it show the ugly built-in error page displaying "404 - File or directory not found."

So, to avoid this, you have to increase the max. allowed request content length for your website in IIS7. That can be done using following command,

appcmd set config "SiteName" -section:requestFiltering -requestLimits.maxAllowedContentLength:209715200 -commitpath:apphost

I have set the max. content length to 200MB.

After doing this setting, the page is succssfully redirected to my error page when I try to upload file of 100MB

Refer, http://weblogs.asp.net/jgalloway/archive/2008/01/08/large-file-uploads-in-asp-net.aspx for more details.

Option 1

localhost/web is equal to localhost:80/web OR to 127.0.0.1:80/web

Option 2

localhost:8080/web is equal to localhost:8080/web OR to 127.0.0.1:8080/web

Yes, there is a way without any 3rd party extension.

I've built javascript-snippet (which you can add as browser-bookmark) and then activate on any site to monitor & modify the requests. :

Usually, if you are using bootstrap you can do this to set a min-height of 100%.

 <div class="container-fluid min-vh-100"></div>

this will also solve the footer not sticking at the bottom.

you can also do this from CSS with the following class

.stickDamnFooter{min-height: 100vh;}

if this class does not stick your footer just add position: fixed; to that same css class and you will not have this issue in a lifetime. Cheers.

in simple manner we all know, we can inherit(extends) one class but we can implements so many interfaces.. that is because in interfaces we don't give an implementation just say the functionality. suppose if java can extends so many classes and those have same methods.. in this point if we try to invoke super class method in the sub class what method suppose to run??, compiler get confused example:- try to multiple extends but in interfaces those methods don't have bodies we should implement those in sub class.. try to multiple implements so no worries..

Via the terminal log on to your database and try this:

database-# >@pathof_mysqlfile.sql

or

database-#>-i pathof_mysqlfile.sql

or

database-#>-c pathof_mysqlfile.sql

Use for...in loop:

for (var key in obj) {
   console.log(' name=' + key + ' value=' + obj[key]);

   // do some more stuff with obj[key]
}

In SQL, the way to do this is to double the apostrophe:

'he doesn''t work for me'

If you are doing this programmatically, you should use an API that accepts parameters and escapes them for you, like prepared statements or similar, rather that escaping and using string concatenation to assemble a query.

From a comment:

I want to sort each set.

That's easy. For any set s (or anything else iterable), sorted(s) returns a list of the elements of s in sorted order:

>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']

Note that sorted is giving you a list, not a set. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2} and {2, 1} are the same set.

You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).

The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key function:

>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']

For more information, see the Sorting HOWTO in the official docs.

* See the comments for exceptions.

I think that an alternative would be to:

• use a tool such as SoapUI (http://www.soapui.org) to record input and output xml messages
• use node request (https://github.com/mikeal/request) to form input xml message to send (POST) the request to the web service (note that standard javascript templating mechanisms such as ejs (http://embeddedjs.com/) or mustache (https://github.com/janl/mustache.js) could help you here) and finally
• use an XML parser to deserialize response data to JavaScript objects

Yes, this is a rather dirty and low level approach but it should work without problems

I just had this occur out of the clear blue. I really do not think I changed anything.

However, Build => Clean Project fixed it.

I don't know much about jQuery, but try this:

row_id = "#5";
row = $("body").find(row_id);

Edit: Of course, if the variable is a number, you have to add "#" to the front:

row_id = 5
row = $("body").find("#"+row_id);

Instead of downloading separate java files as suggested by Veer, you could just add this JAR file to your package.

To add the jar file to your project in Eclipse, do the following:

1. Right click on your project, click Build Path > Configure Build Path
2. Goto Libraries tab > Add External JARs
3. Locate the JAR file and add

In java there is a length field that you can use on any array to find out it's size:

    String[] s = new String[10];
    System.out.println(s.length);

System is a final class from the java.lang package.

out is a class variable of type PrintStream declared in the System class.

println is a method of the PrintStream class.

If you are setting the path in Catalina use below command one after another in the terminal. It's working fine for me.

Visual Studio Code 1.6.1 supports "Format On Save" which will automatically pick up relevant installed formatter extensions and format the whole document on each save.

Enable "Format On Save" by setting

"editor.formatOnSave": true

And there are available keyboard shortcuts (Visual Studio Code 1.7 and above):

Format the whole document: Shift + Alt + F

Format Selection only: Ctrl + K, Ctrl + F

See documentation.

I use:

• express and
• morgan
  
  

Install Node.js. and npm. npm is installed with Node.js

Placed inside the root project directory

$ cd <your_angularjs_project>

The next command creates package.json

$ npm init

Install express ==> Fast, unopinionated, minimalist for node:

$ npm install express --save

Install morgan ==> HTTP request logger middleware for node.js

$ npm install morgan --save

create file server.js

add the following code in server.js file

// Required Modules
var express    = require("express");
var morgan     = require("morgan");
var app        = express();

var port = process.env.PORT || 3002;

app.use(morgan("dev"));
app.use(express.static("./"));

app.get("/", function(req, res) {
    res.sendFile("./index.html"); //index.html file of your angularjs application
});

// Start Server
app.listen(port, function () {
    console.log( "Express server listening on port " + port);
});

Finally run your AngularJS project in localhost server:

$ node server.js

You can also use the FileReader class :

    var reader = new FileReader();
    reader.onload = function (e) {
        var data = this.result;
    }
    reader.readAsDataURL( file );

An abstract class is a type of class that can only be used as a base class for another class; such thus cannot be instantiated. To make a class abstract, the keyword abstract is used. Abstract classes may have one or more abstract methods that only have a header line (no method body). The method header line ends with a semicolon (;). Any class that is derived from the base class can define the method body in a way that is consistent with the header line using all the designated parameters and returning the correct data type (if the return type is not void). An abstract method acts as a place holder; all derived classes are expected to override and complete the method.

Example in Java

abstract public class Shape

{

double area;

public abstract double getArea();

}

import os, os.path

To get (full-path) immediate sub-directories in a directory:

def SubDirPath (d):
    return filter(os.path.isdir, [os.path.join(d,f) for f in os.listdir(d)])

To get the latest (newest) sub-directory:

def LatestDirectory (d):
    return max(SubDirPath(d), key=os.path.getmtime)

hg status will show you all the new files, and then you can just rm them.

Normally I want to get rid of ignored and unversioned files, so:

hg status -iu                          # to show 
hg status -iun0 | xargs -r0 rm         # to destroy

And then follow that with:

hg update -C -r xxxxx

which puts all the versioned files in the right state for revision xxxx

To follow the Stack Overflow tradition of telling you that you don't want to do this, I often find that this "Nuclear Option" has destroyed stuff I care about.

The right way to do it is to have a 'make clean' option in your build process, and maybe a 'make reallyclean' and 'make distclean' too.

Edit: As has been noted in the other answers, the standard actually guarantees that "the resulting value is the least unsigned integer congruent to the source integer (modulo 2n where n is the number of bits used to represent the unsigned type)". So even if your platform did not store signed ints as two's complement, the behavior would be the same.

Apparently your signed integer -62 is stored in two's complement (Wikipedia) on your platform:

62 as a 32-bit integer written in binary is

0000 0000 0000 0000 0000 0000 0011 1110

To compute the two's complement (for storing -62), first invert all the bits

1111 1111 1111 1111 1111 1111 1100 0001

then add one

1111 1111 1111 1111 1111 1111 1100 0010

And if you interpret this as an unsigned 32-bit integer (as your computer will do if you cast it), you'll end up with 4294967234 :-)

.html() only takes a string OR a function as an argument, not both. Try this:

 $("#showDiv").click(function () {
     $('#theDiv').show(1000, function () {
         setTimeout(function () {
             $('#theDiv').html(function () {
                 setTimeout(function () {
                     $('#theDiv').html('Here is some replacement text');
                 }, 0);
                 setTimeout(function () {
                     $('#theDiv').html('More replacement text goes here');
                 }, 2500);
             });
         }, 2500);
     });
 }); //click function ends

jsFiddle example

You cannot create different "variable names" but you can create different object properties. There are many ways to do whatever it is you're actually trying to accomplish. In your case I would just do

for (var i = myArray.length - 1; i >= 0; i--) {    console.log(eval(myArray[i])); }; 

More generally you can create object properties dynamically, which is the type of flexibility you're thinking of.

var result = {}; for (var i = myArray.length - 1; i >= 0; i--) {     result[myArray[i]] = eval(myArray[i]);   }; 

I'm being a little handwavey since I don't actually understand language theory, but in pure Javascript (including Node) references (i.e. variable names) are happening at a higher level than at runtime. More like at the call stack; you certainly can't manufacture them in your code like you produce objects or arrays. Browsers do actually let you do this anyway though it's terrible practice, via

window['myVarName'] = 'namingCollisionsAreFun';  

(per comment)

So I finally got it(http://jsfiddle.net/ncapito/eYtU5/):

    height: 100%;
    display: inline-block;
    vertical-align: middle;
}

.center {

    vertical-align: middle;
}

        <div class='centerWrapper'>
            <div class='center'> <i class='icon-user'></i></div>

The cleanest way, as far as I know:

1. add your JSP variable to an HTML element's data-* attribute
2. then read this value via Javascript when required

My opinion regarding the current solutions on this SO page: reading "directly" JSP values using java scriplet inside actual javascript code is probably the most disgusting thing you could do. Makes me wanna puke. haha. Seriously, try to not do it.

The HTML part without JSP:

<body data-customvalueone="1st Interpreted Jsp Value" data-customvaluetwo="another Interpreted Jsp Value">
    Here is your regular page main content
</body>

The HTML part when using JSP:

<body data-customvalueone="${beanName.attrName}" data-customvaluetwo="${beanName.scndAttrName}">
    Here is your regular page main content
</body>

The javascript part (using jQuery for simplicity):

<script type="text/JavaScript" src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.js"></script>

You don't need to copy a Python string. They are immutable, and the copy module always returns the original in such cases, as do str(), the whole string slice, and concatenating with an empty string.

Moreover, your 'hello' string is interned (certain strings are). Python deliberately tries to keep just the one copy, as that makes dictionary lookups faster.

One way you could work around this is to actually create a new string, then slice that string back to the original content:

>>> a = 'hello'
>>> b = (a + '.')[:-1]
>>> id(a), id(b)
(4435312528, 4435312432)

But all you are doing now is waste memory. It is not as if you can mutate these string objects in any way, after all.

If all you wanted to know is how much memory a Python object requires, use sys.getsizeof(); it gives you the memory footprint of any Python object.

For containers this does not include the contents; you'd have to recurse into each container to calculate a total memory size:

>>> import sys
>>> a = 'hello'
>>> sys.getsizeof(a)
42
>>> b = {'foo': 'bar'}
>>> sys.getsizeof(b)
280
>>> sys.getsizeof(b) + sum(sys.getsizeof(k) + sys.getsizeof(v) for k, v in b.items())
360

You can then choose to use id() tracking to take an actual memory footprint or to estimate a maximum footprint if objects were not cached and reused.

Since I18n is the Rails core feature starting from version 2.2 you can use its localize-method. By applying the forementioned strftime %-variables you can specify the desired format under config/locales/en.yml (or whatever language), in your case like this:

time:
  formats:
    default: '%FT%T'

Or if you want to use this kind of format in a few specific places you can refer it as a variable like this

time:
  formats:
    specific_format: '%FT%T'

After that you can use it in your views like this:

l(Mode.last.created_at, format: :specific_format)  

I had the same problem with e1071 package. Just close any other R sessions running parallelly and you will be good to go.

I've had the same problem you describe. The web site I'm building can be accessed from a mobile phone and from the browser so I need an api to allow users to signup, login and do some specific tasks. Furthermore, I need to support scalability, the same code running on different processes/machines.

Because users can CREATE resources (aka POST/PUT actions) you need to secure your api. You can use oauth or you can build your own solution but keep in mind that all the solutions can be broken if the password it's really easy to discover. The basic idea is to authenticate users using the username, password and a token, aka the apitoken. This apitoken can be generated using node-uuid and the password can be hashed using pbkdf2

Then, you need to save the session somewhere. If you save it in memory in a plain object, if you kill the server and reboot it again the session will be destroyed. Also, this is not scalable. If you use haproxy to load balance between machines or if you simply use workers, this session state will be stored in a single process so if the same user is redirected to another process/machine it will need to authenticate again. Therefore you need to store the session in a common place. This is typically done using redis.

When the user is authenticated (username+password+apitoken) generate another token for the session, aka accesstoken. Again, with node-uuid. Send to the user the accesstoken and the userid. The userid (key) and the accesstoken (value) are stored in redis with and expire time, e.g. 1h.

Now, every time the user does any operation using the rest api it will need to send the userid and the accesstoken.

If you allow the users to signup using the rest api, you'll need to create an admin account with an admin apitoken and store them in the mobile app (encrypt username+password+apitoken) because new users won't have an apitoken when they sign up.

The web also uses this api but you don't need to use apitokens. You can use express with a redis store or use the same technique described above but bypassing the apitoken check and returning to the user the userid+accesstoken in a cookie.

If you have private areas compare the username with the allowed users when they authenticate. You can also apply roles to the users.

Summary:

An alternative without apitoken would be to use HTTPS and to send the username and password in the Authorization header and cache the username in redis.

My solution to not having sessionStorage transferable over tabs was to create a localProfile and bang off this variable. If this variable is set but my sessionStorage variables arent go ahead and reinitialize them. When user logs out window closes destroy this localStorage variable

I had the app uninstalled and got the INSTALL_FAILED_DEXOPT error nevertheless. If you are working with Android Studio / gradle: gradle clean did the trick for me, Cheers.

You need to pass the whole point to location

var point = new Point(50, 100);
this.balancePanel.Location = point;

There's two parts to this question, really.

1. Q: Which browsers support the "async" attribute on a script tag in markup?

   A: IE10p2+, Chrome 11+, Safari 5+, Firefox 3.6+

2. Q: Which browsers support the new spec that defines behavior for the "async" property in JavaScript, on a dynamically created script element?

   A: IE10p2+, Chrome 12+, Safari 5.1+, Firefox 4+

As for Opera, they are very close to releasing a version which will support both types of async. I've been working with them closely on this, and it should come out soon (I hope!).

More info on ordered-async (aka, "async=false") can be found here: http://wiki.whatwg.org/wiki/Dynamic_Script_Execution_Order

Also, to test if a browser supports the new dynamic async property behavior: http://test.getify.com/test-async/

If you still continue to get the error even after setting the JAVA_HOME variable Copy the studio folder to your C drive and then run the studio.exe or studio64.exe depending upon your java versio

I disagree with yydi answer saying:

If Android decides to recreate your Fragment later, it's going to call the no-argument constructor of your fragment. So overloading the constructor is not a solution.

I think it is a solution and a good one, this is exactly the reason it been developed by Java core language.

Its true that Android system can destroy and recreate your Fragment. So you can do this:

public MyFragment() {
//  An empty constructor for Android System to use, otherwise exception may occur.
}

public MyFragment(int someInt) {
    Bundle args = new Bundle();
    args.putInt("someInt", someInt);
    setArguments(args);
}

It will allow you to pull someInt from getArguments() latter on, even if the Fragment been recreated by the system. This is more elegant solution than static constructor.

For my opinion static constructors are useless and should not be used. Also they will limit you if in the future you would like to extend this Fragment and add more functionality to the constructor. With static constructor you can't do this.

Update:

Android added inspection that flag all non-default constructors with an error.
I recommend to disable it, for the reasons mentioned above.

Here is a util class for marshaling and unmarshaling objects. In my case it was a nested class, so I made it static JAXBUtils.

import javax.xml.bind.JAXB;
import java.io.StringReader;
import java.io.StringWriter;

public class JAXBUtils
{
    /**
     * Unmarshal an XML string
     * @param xml     The XML string
     * @param type    The JAXB class type.
     * @return The unmarshalled object.
     */
    public <T> T unmarshal(String xml, Class<T> type)
    {
        StringReader reader = new StringReader(xml);
        return javax.xml.bind.JAXB.unmarshal(reader, type);
    }

    /**
     * Marshal an Object to XML.
     * @param object    The object to marshal.
     * @return The XML string representation of the object.
     */
    public String marshal(Object object)
    {
        StringWriter stringWriter = new StringWriter();
        JAXB.marshal(object, stringWriter);
        return stringWriter.toString();
    }
}

For Oracle versions which does not support the WM_CONCAT, the following can be used

  select "User", RTRIM(
     XMLAGG (XMLELEMENT(e, department||',') ORDER BY department).EXTRACT('//text()') , ','
     ) AS departments 
  from yourtable 
  group by "User"

This one is much more powerful and flexible - you can specify both delimiters and sort order within each group as in listagg.

I wrestled with this problem and implemented the 'convertToNull' solutions discussed above. It worked in my local MySql instance. But when I deployed my Play/Scala app to Heroku it no longer would work. Heroku also concatenates several args to the DB URL that they provide users, and this solution, because of Heroku's use concatenation of "?" before their own set of args, will not work. However I found a different solution which seems to work equally well.

SET sql_mode = 'NO_ZERO_DATE';

I put this in my table descriptions and it solved the problem of '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp

I would use something like this for fixed length, like hashes:

md5sum = String.format("%032x", new BigInteger(1, md.digest()));

You can with flexbox:

ul.list {
    padding: 0;
    list-style: none;
    display: flex;
    align-items: stretch;
    justify-items: center;
    flex-wrap: wrap;
    justify-content: center;
}
li {
    width: 100px;
    padding: .5rem;
    border-radius: 1rem;
    background: yellow;
    margin: 0 5px;
}

<ul class="list">
  <li>title 1</li>
  <li>title 2<br>new line</li>
  <li>title 3<br>new<br>line</li>
</ul>

To be up to date for upper versions and later visitors :

Currently I'm working on a win7 64bit having different tools on it including python 2.7.4 as a prerequisite for google android ...

When I upgraded from WB 6.0.8-win32 to upper versions to have 64bit performance I had some problems for example on 6.3.5-winx64 I had a bug in the details view of tables (disordered view) caused me to downgrade to 6.2.5-winx64.

As a GUI user, easy forward/backward engineering and db server relative items were working well but when we try to Database>Connect to Database we will have Not connected and will have python error if we try to execute a query however the DB server service is absolutely ran and is working well and this problem is not from the server and is from workbench. To resolve it we must use Query>Reconnect to Server to choose the DB connection explicitly and then almost everything looks good (this may be due to my multiple db connections and I couldn't find some solution to define the default db connection in workbench).

As a note : because I'm using latest Xampp version (even in linux addictively :) ), recently Xampp uses mariadb 10 instead of mysql 5.x causes the mysql file version to be 10 may cause some problems such as forward engineering of procedures which can be resolved via mysql_upgrade.exe but still when we try to check a db connection wb will inform about the wrong version however it is not critical and works well.

Conclusion : Thus sometimes db connection problems in workbench may be due to itself and not server (if you don't have other db connection relative problems).

Even though there are multiple answers, there is an issue using this approach. It selects all the text that matches, not only the whole words like variables.

As per "Sublime Text: Select all instances of a variable and edit variable name" and the answer in "Sublime Text: Select all instances of a variable and edit variable name", we have to start with a empty selection. That is, start using the shortcut Alt+F3 which would help selecting only the whole words.

I agree with Matti. Would be easy to do with some simple javascript. A quick jquery example would be something like this:

<tr>
  <td><a href="http://www.example.com/">example</a></td>
  <td>another cell</td>
  <td>one more</td>
</tr>

and

$('tr').click( function() {
    window.location = $(this).find('a').attr('href');
}).hover( function() {
    $(this).toggleClass('hover');
});

then in your CSS

tr.hover {
   cursor: pointer;
   /* whatever other hover styles you want */
}

Try the following:

var count=Object.keys(result).length;

Does not work IE8 and lower.

For FIRE STICK 4K it actually says in the dialog:

Otherwise check for a confirmation dialog on your device

Indeed on the TV in the other room there was a confirmation dialog. Doh'!

If for a block cipher you're not going to use a Cipher transformation that includes a padding scheme, you need to have the number of bytes in the plaintext be an integral multiple of the block size of the cipher.

So either pad out your plaintext to a multiple of 16 bytes (which is the AES block size), or specify a padding scheme when you create your Cipher objects. For example, you could use:

Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");

Unless you have a good reason not to, use a padding scheme that's already part of the JCE implementation. They've thought out a number of subtleties and corner cases you'll have to realize and deal with on your own otherwise.

Ok, your second problem is that you are using String to hold the ciphertext.

In general,

String s = new String(someBytes);
byte[] retrievedBytes = s.getBytes();

will not have someBytes and retrievedBytes being identical.

If you want/have to hold the ciphertext in a String, base64-encode the ciphertext bytes first and construct the String from the base64-encoded bytes. Then when you decrypt you'll getBytes() to get the base64-encoded bytes out of the String, then base64-decode them to get the real ciphertext, then decrypt that.

The reason for this problem is that most (all?) character encodings are not capable of mapping arbitrary bytes to valid characters. So when you create your String from the ciphertext, the String constructor (which applies a character encoding to turn the bytes into characters) essentially has to throw away some of the bytes because it can make no sense of them. Thus, when you get bytes out of the string, they are not the same bytes you put into the string.

In Java (and in modern programming in general), you cannot assume that one character = one byte, unless you know absolutely you're dealing with ASCII. This is why you need to use base64 (or something like it) if you want to build strings from arbitrary bytes.

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

You should create new SSH key set for that Docker image, as you probably don't want to embed there your own private key. To make it work, you'll have to add that key to deployment keys in your git repository. Here's complete recipe:

1. Generate ssh keys with ssh-keygen -q -t rsa -N '' -f repo-key which will give you repo-key and repo-key.pub files.

2. Add repo-key.pub to your repository deployment keys.
   On GitHub, go to [your repository] -> Settings -> Deploy keys

3. Add something like this to your Dockerfile:

   ADD repo-key /
   RUN \
     chmod 600 /repo-key && \  
     echo "IdentityFile /repo-key" >> /etc/ssh/ssh_config && \  
     echo -e "StrictHostKeyChecking no" >> /etc/ssh/ssh_config && \  
     // your git clone commands here...
   

Note that above switches off StrictHostKeyChecking, so you don't need .ssh/known_hosts. Although I probably like more the solution with ssh-keyscan in one of the answers above.

Off the top of my head:

• Use GetType() instead of typeof(Page) in order to bind the script to your actual page class instead of the base class,
• Pass a key constant instead of Page.UniqueID, which is not that meaningful since it's supposed to be used by named controls,
• End your Javascript statement with a semicolon,
• Register the script during the PreRender phase:

protected void Page_PreRender(object sender, EventArgs e)
{
    ScriptManager.RegisterStartupScript(this, GetType(), "YourUniqueScriptKey", 
        "alert('This pops up');", true);
}

I have shell script in Linux and following code worked for me:

#!/bin/bash
yesterday=`TZ=EST+24 date +%Y%m%d` # Yesterday is a variable
mkdir $yesterday # creates a directory with  YYYYMMDD format

Got a gotcha for those with their headspace in Pandas and moving to pyspark

 from pyspark import SparkConf, SparkContext
 from pyspark.sql import SQLContext

 spark_conf = SparkConf().setMaster("local").setAppName("MyAppName")
 sc = SparkContext(conf = spark_conf)
 sqlContext = SQLContext(sc)

 records = [
     {"colour": "red"},
     {"colour": "blue"},
     {"colour": None},
 ]

 pandas_df = pd.DataFrame.from_dict(records)
 pyspark_df = sqlContext.createDataFrame(records)

So if we wanted the rows that are not red:

pandas_df[~pandas_df["colour"].isin(["red"])]

Looking good, and in our pyspark DataFrame

pyspark_df.filter(~pyspark_df["colour"].isin(["red"])).collect()

So after some digging, I found this: https://issues.apache.org/jira/browse/SPARK-20617 So to include nothingness in our results:

pyspark_df.filter(~pyspark_df["colour"].isin(["red"]) | pyspark_df["colour"].isNull()).show()

Delimiters, delimiters...

You really need them when there are multiple statements in your procedure. (in other words, do you have a ; in your code and then more statements/commands? Then, you need to use delimiters).

For such a simpler rpocedure as yours though, you could just do:

CREATE PROCEDURE ProG()
  SELECT * FROM `hs_hr_employee_leave_quota`;

It depends on the relation between your components (parent / child) but the best / generic way to make communicate components is to use a shared service.

See this doc for more details:

• https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#bidirectional-service

That being said, you could use the following to provide an instance of the com1 into com2:

<div>
  <com1 #com1>...</com1>
  <com2 [com1ref]="com1">...</com2>
</div>

In com2, you can use the following:

@Component({
  selector:'com2'
})
export class com2{
  @Input()
  com1ref:com1;

  function2(){
    // i want to call function 1 from com1 here
    this.com1ref.function1();
  }
}

In Web Application Projects, Visual Studio needs additional .designer files for pages and user controls. Web Site Projects do not require this overhead. The markup itself is interpreted as the design.

Safe navigation operator or Existential Operator or Null Propagation Operator is supported in Angular Template. Suppose you have Component class

  myObj:any = {
    doSomething: function () { console.log('doing something'); return 'doing something'; },
  };
  myArray:any;
  constructor() { }

  ngOnInit() {
    this.myArray = [this.myObj];
  }

You can use it in template html file as following:

<div>test-1: {{  myObj?.doSomething()}}</div>
<div>test-2: {{  myArray[0].doSomething()}}</div>
<div>test-3: {{  myArray[2]?.doSomething()}}</div>

You can use

DispatchQueue.main.asyncAfter(deadline: .now() + .microseconds(100)) {
        // Code
    }

One point I noticed with Primefaces 3.4 and Netbeans 7.2:

Remove the Netbeans auto-filled parameters for function handleFileUpload i.e. (event) otherwise event could be null.

<h:form>
    <p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload(event)}"
        mode="advanced" 
        update="messages"
        sizeLimit="100000" 
        allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>

    <p:growl id="messages" showDetail="true"/>
</h:form>

If you want the content string and this string does not have parameters you can use

    String line = null;
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null){
        System.out.println(line);
    }

In May 2017 Google launched the official Google Maps URLs documentation. The Google Maps URLs introduces universal cross-platform syntax that you can use in your applications.

Have a look at the following document:

https://developers.google.com/maps/documentation/urls/guide

You can use URLs in search, directions, map and street view modes.

For example, to show the marker at specified position you can use the following URL:

https://www.google.com/maps/search/?api=1&query=36.26577,-92.54324

For further details please read aforementioned documentation.

You can also file feature requests for this API in Google issue tracker.

Hope this helps!

It depends on the database to which you're trying to connect, the method by which you created the connection, and the version of Excel that you're using. (Also, most probably, the version of the relevant ODBC driver on your computer.)

The following examples are using SQL Server 2008 and Excel 2007, both on my local machine.

When I used the Data Connection Wizard (on the Data tab of the ribbon, in the Get External Data section, under From Other Sources), I saw the same thing that you did: the Parameters button was disabled, and adding a parameter to the query, something like select field from table where field2 = ?, caused Excel to complain that the value for the parameter had not been specified, and the changes were not saved.

When I used Microsoft Query (same place as the Data Connection Wizard), I was able to create parameters, specify a display name for them, and enter values each time the query was run. Bringing up the Connection Properties for that connection, the Parameters... button is enabled, and the parameters can be modified and used as I think you want.

I was also able to do this with an Access database. It seems reasonable that Microsoft Query could be used to create parameterized queries hitting other types of databases, but I can't easily test that right now.

Had several modules complain about patch does not apply. One thing I was missing out was that the branches had become stale. After the git merge master generated the patch files using git diff master BRANCH > file.patch. Going to the vanilla branch was able to apply the patch with git apply file.patch

If you want to concatenate the fields using / as a separator, you can use concat_ws:

select concat_ws('/', col1, col2, col3) from mytable

You cannot escape listing the columns in the query though. The *-syntax works only in "select * from". You can list the columns and construct the query dynamically though.

DataTable, DbDataReader, or IEnumerable<SqlDataRecord> objects can be used to populate a table-valued parameter per the MSDN article Table-Valued Parameters in SQL Server 2008 (ADO.NET).

The following example illustrates using either a DataTable or an IEnumerable<SqlDataRecord>:

SQL Code:

CREATE TABLE dbo.PageView
(
    PageViewID BIGINT NOT NULL CONSTRAINT pkPageView PRIMARY KEY CLUSTERED,
    PageViewCount BIGINT NOT NULL
);
CREATE TYPE dbo.PageViewTableType AS TABLE
(
    PageViewID BIGINT NOT NULL
);
CREATE PROCEDURE dbo.procMergePageView
    @Display dbo.PageViewTableType READONLY
AS
BEGIN
    MERGE INTO dbo.PageView AS T
    USING @Display AS S
    ON T.PageViewID = S.PageViewID
    WHEN MATCHED THEN UPDATE SET T.PageViewCount = T.PageViewCount + 1
    WHEN NOT MATCHED THEN INSERT VALUES(S.PageViewID, 1);
END

C# Code:

private static void ExecuteProcedure(bool useDataTable, 
                                     string connectionString, 
                                     IEnumerable<long> ids) 
{
    using (SqlConnection connection = new SqlConnection(connectionString)) 
    {
        connection.Open();
        using (SqlCommand command = connection.CreateCommand()) 
        {
            command.CommandText = "dbo.procMergePageView";
            command.CommandType = CommandType.StoredProcedure;

            SqlParameter parameter;
            if (useDataTable) {
                parameter = command.Parameters
                              .AddWithValue("@Display", CreateDataTable(ids));
            }

            {
                parameter = command.Parameters

            }
            parameter.SqlDbType = SqlDbType.Structured;
            parameter.TypeName = "dbo.PageViewTableType";

            command.ExecuteNonQuery();
        }
    }
}

private static DataTable CreateDataTable(IEnumerable<long> ids) 
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(long));
    foreach (long id in ids) 
    {
        table.Rows.Add(id);
    }
    return table;
}

private static IEnumerable<SqlDataRecord> CreateSqlDataRecords(IEnumerable<long> ids) 
{
    SqlMetaData[] metaData = new SqlMetaData[1];
    metaData[0] = new SqlMetaData("ID", SqlDbType.BigInt);
    SqlDataRecord record = new SqlDataRecord(metaData);
    foreach (long id in ids) 
    {
        record.SetInt64(0, id);
        yield return record;
    }
}

• TESTED with jquery 1.11.3 & jquery-ui 1.11.4

You can achieve 2 way data-binding in Nuxt/Vue like this:

Child.vue

<template>
    <input

       <!-- How you choose to emit the event is up to you could be @keydown or even inside a watch prop -->
      @keyup="$emit('update:dataFromParent', content)"
    />
</template>

<script>
export default {
  props: ["dataFromParent"],
  mounted() {
    this.content = this.dataFromParent;
  },
  data: () => ({
    content: "",
  }),
};
</script>

Parent.vue

<tenplate>
  <Child :dataFromParent.sync="text" />
</template>

<script>
import Child from "~/components/Child";

export default {
  components: {
    Child,
  },
  data: () => ({
    text: "Hello World!" ,
  }),
 
};
</script>

jQuery('#querytableDatasets').dataTable({  
        "bAutoWidth": false
});

• pyenv - manages different python versions,
• all others - create virtual environment (which has isolated python version and installed "requirements"),

pipenv want combine all, in addition to previous it installs "requirements" (into the active virtual environment or create its own if none is active)

So maybe you will be happy with pipenv only.

But I use: pyenv + pyenv-virtualenvwrapper, + pipenv (pipenv for installing requirements only).

In Debian:

1. apt install libffi-dev

2. install pyenv based on https://www.tecmint.com/pyenv-install-and-manage-multiple-python-versions-in-linux/, but..

3. .. but instead of pyenv-virtualenv install pyenv-virtualenvwrapper (which can be standalone library or pyenv plugin, here the 2nd option):

   pyenv install 3.9.0

   git clone https://github.com/pyenv/pyenv-virtualenvwrapper.git $(pyenv root)/plugins/pyenv-virtualenvwrapper

   into ~/.bashrc add: export $VIRTUALENVWRAPPER_PYTHON="/usr/bin/python3"

   source ~/.bashrc

   pyenv virtualenvwrapper

Then create virtual environments for your projects (workingdir must exist):

pyenv local 3.9.0  # to prevent 'interpreter not found' in mkvirtualenv
python -m pip install --upgrade pip setuptools wheel
mkvirtualenv <venvname> -p python3.9 -a <workingdir>

and switch between projects:

workon <venvname>
python -m pip install --upgrade pip setuptools wheel pipenv

Inside a project I have the file requirements.txt, without fixing the versions inside (if some version limitation is not neccessary). You have 2 possible tools to install them into the current virtual environment: pip-tools or pipenv. Lets say you will use pipenv:

pipenv install -r requirements.txt

this will create Pipfile and Pipfile.lock files, fixed versions are in the 2nd one. If you want reinstall somewhere exactly same versions then (Pipfile.lock must be present):

pipenv install

Remember that Pipfile.lock is related to some Python version and need to be recreated if you use a different one.

As you see I write requirements.txt. This has some problems: You must remove a removed package from Pipfile too. So writing Pipfile directly is probably better.

So you can see I use pipenv very poorly. Maybe if you will use it well, it can replace everything?

EDIT 2021.01: I have changed my stack to: pyenv + pyenv-virtualenvwrapper + poetry. Ie. I use no apt or pip installation of virtualenv or virtualenvwrapper, and instead I install pyenv's plugin pyenv-virtualenvwrapper. This is easier way.

Poetry is great for me:

poetry add <package>   # install single package
poetry remove <package>
poetry install   # if you remove poetry.lock poetry will re-calculate versions

There is also quick solution using the imputeTS package:

library(imputeTS)
na_mean(yourDataFrame)

I use this 3rd party pagination library and it works well. It can do local/remote datasources and it's very configurable.

    [direction-links=""]
    [boundary-links=""]
    [on-page-change=""]
    [pagination-id=""]
    [template-url=""]
    [auto-hide=""]>
    </dir-pagination-controls>

WORKING FIDDLE

I was having almost the same problem as this but slightly different on Server 2012 R2. I have a powershell script in Task Scheduler that copies 3 files from one location to another. If I run the script manually from powershell, it works like a charm. But when run from Task Scheduler, it only copies the first 2 small files, then hang on the 3rd (large file). And I was also getting a result of "The operator or administrator has refused the request". And I have done almost everything in this forum.

Here is the scenario and how I fixed it for me. May not work for others, but just in case it will:

Scenario: 1. Powershell script in Task Scheduler 2. Ran using a domain account which is a local admin on the server 3. Selected 'Run whether user is logged on or not" 4. Run with highest priviledges

Fix: 1. I had to login to the server using the domain account so that it created a local profile in C:\Users. 2. Checked and made user that the user has access to all the drives I referred to on my script

I believe #1 is the main fix for me. I hope this works for others out there.

WebRequest being abstract (and since any inheriting class must override the Headers property).. which concrete WebRequest are you using ? In other words, how do you get that WebRequest object to beign with ?

ehr.. mnour answer made me realize that the error message you were getting is actually spot on: it's telling you that the header you are trying to add already exist and you should then modify its value using the appropriate property (the indexer, for instance), instead of trying to add it again. That's probably all you were looking for.

Other classes inheriting from WebRequest might have even better properties wrapping certain headers; See this post for instance.

No, the URL will always be updated when params are passed to transitionTo.

This happens on state.js:698 in ui-router.

Its simple try below code --

a{
outline: medium none !important;
}

If happy cheers! Good day

The simplest in my opinion is just this:

it = iter([1,2,3,4,5,6])
for x, y in zip(it, it):
    print x, y

Out: 1 2
     3 4
     5 6

No extra imports or anything. And very elegant, in my opinion.

Consider Approach 1 with reshape method and Approach 2 with np.newaxis method that produce the same outcome:

#Lets suppose, we have:
x = [1,2,3,4,5,6,7,8,9]
print('I. x',x)

xNpArr = np.array(x)
print('II. xNpArr',xNpArr)
print('III. xNpArr', xNpArr.shape)

xNpArr_3x3 = xNpArr.reshape((3,3))
print('IV. xNpArr_3x3.shape', xNpArr_3x3.shape)
print('V. xNpArr_3x3', xNpArr_3x3)

#Approach 1 with reshape method
xNpArrRs_1x3x3x1 = xNpArr_3x3.reshape((1,3,3,1))
print('VI. xNpArrRs_1x3x3x1.shape', xNpArrRs_1x3x3x1.shape)
print('VII. xNpArrRs_1x3x3x1', xNpArrRs_1x3x3x1)

#Approach 2 with np.newaxis method
xNpArrNa_1x3x3x1 = xNpArr_3x3[np.newaxis, ..., np.newaxis]
print('VIII. xNpArrNa_1x3x3x1.shape', xNpArrNa_1x3x3x1.shape)
print('IX. xNpArrNa_1x3x3x1', xNpArrNa_1x3x3x1)

We have as outcome:

I. x [1, 2, 3, 4, 5, 6, 7, 8, 9]

II. xNpArr [1 2 3 4 5 6 7 8 9]

III. xNpArr (9,)

IV. xNpArr_3x3.shape (3, 3)

V. xNpArr_3x3 [[1 2 3]
 [4 5 6]
 [7 8 9]]

VI. xNpArrRs_1x3x3x1.shape (1, 3, 3, 1)

VII. xNpArrRs_1x3x3x1 [[[[1]
   [2]
   [3]]

  [[4]
   [5]
   [6]]

  [[7]
   [8]

VIII. xNpArrNa_1x3x3x1.shape (1, 3, 3, 1)

IX. xNpArrNa_1x3x3x1 [[[[1]

No, there is no inline function in java. Yes, you can use a public static method anywhere in the code when placed in a public class. The java compiler may do inline expansion on a static or final method, but that is not guaranteed.

Typically such code optimizations are done by the compiler in combination with the JVM/JIT/HotSpot for code segments used very often. Also other optimization concepts like register declaration of parameters are not known in java.

Optimizations cannot be forced by declaration in java, but done by compiler and JIT. In many other languages these declarations are often only compiler hints (you can declare more register parameters than the processor has, the rest is ignored).

Declaring java methods static, final or private are also hints for the compiler. You should use it, but no garantees. Java performance is dynamic, not static. First call to a system is always slow because of class loading. Next calls are faster, but depending on memory and runtime the most common calls are optimized withinthe running system, so a server may become faster during runtime!

delete is not overly complicated :

myStringBuilder.delete(0, myStringBuilder.length());

You can also do :

myStringBuilder.setLength(0);

This issue is quite possibly due to exceeding the 65K methods dex limit imposed by Android. This problem can be solved either by cleaning the project, and removing some unused libraries and methods from dependencies in build.gradle, OR by adding multidex support.

So, If you have to keep libraries and methods, then you can enable multi dex support by declaring it in the gradle config.

defaultConfig {        
    // Enabling multidex support.
    multiDexEnabled true
}

You can read more about multidex support and developing apps with more than 65K methods here.

I would do something like this:

;WITH x 
 AS (SELECT *, 
            Row_number() 
              OVER( 
                partition BY employeeid 
                ORDER BY datestart) rn 
     FROM   employeehistory) 
SELECT * 
FROM   x x1 
   LEFT OUTER JOIN x x2 
                ON x1.rn = x2.rn + 1 

Or maybe it would be x2.rn - 1. You'll have to see. In any case, you get the idea. Once you have the table joined on itself, you can filter, group, sort, etc. to get what you need.

See numpy.clip:

index = numpy.clip(index, 0, len(my_list) - 1)

interesting, datepicker default date is current date as I found,

but you can set date by

$("#yourinput").datepicker( "setDate" , "7/11/2011" );

don't forget to check you system date :)

You need to break;, throw, goto, or return from each of your case labels. In a loop you may also continue.

        switch (searchType)
        {
            case "SearchBooks":
                Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
                break;

            case "SearchAuthors":
                Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
                break;
        }

The only time this isn't true is when the case labels are stacked like this:

 case "SearchBooks": // no code inbetween case labels.
 case "SearchAuthors":
    // handle both of these cases the same way.
    break;

Meaning.

In brief, $@ expands to the positional arguments passed from the caller to either a function or a script. Its meaning is context-dependent: Inside a function, it expands to the arguments passed to such function. If used in a script (not inside the scope a function), it expands to the arguments passed to such script.

$ cat my-sh
#! /bin/sh
echo "$@"

$ ./my-sh "Hi!"
Hi!

$ put () ( echo "$@" )
$ put "Hi!"
Hi!

Word splitting.

Now, another topic that is of paramount importance when understanding how $@ behaves in the shell is word splitting. The shell splits tokens based on the contents of the IFS variable. Its default value is \t\n; i.e., whitespace, tab, and newline.

Expanding "$@" gives you a pristine copy of the arguments passed. However, expanding $@ will not always. More specifically, if the arguments contain characters from IFS, they will split.

Most of the time what you will want to use is "$@", not $@.

This did the trick for me:

echo trim($entry->title);

#undef near
#undef far

When I was new to game programming I was writing a frustum for a camera class is a game that I wrote, I had really strange errors in my code.

It turns out that Microsoft had some #defines for near and far in windows.h which caused my _near and _far variables to error on the lines that contained them. It was very difficult to track the problem down because (I was a newbie at the time) and they only existed on four lines in the whole project so i didn't realise right away.

Faced the same issue and resolved by upgrading my Maven from 3.0.4 to 3.1.1. Please try with v3.1.1 or any higher version if available

With your own Code and a Slight Change withou jQuery,

function testingAPI(){ 
    var key = "8a1c6a354c884c658ff29a8636fd7c18"; 
    var url = "https://api.fantasydata.net/nfl/v2/JSON/PlayerSeasonStats/2015";
    console.log(httpGet(url,key)); 
}


function httpGet(url,key){
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", url, false );
    xmlHttp.setRequestHeader("Ocp-Apim-Subscription-Key",key);
    xmlHttp.send(null);
    return xmlHttp.responseText;
}

Thank You

In the list of arguments, each entry must be on its own. Using

output = subprocess.check_output(["ping", "-c","2", "-W","2", "1.1.1.1"])

should fix your problem.

The main concept of partial view is returning the HTML code rather than going to the partial view it self.

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

this action return the HTML code of the partial view ("HolidayPartialView").

To refresh partial view replace the existing item with the new filtered item using the jQuery below.

$.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });

from p in context.ParentTable
join c in context.ChildTable on p.ParentId equals c.ChildParentId into j1
from j2 in j1.DefaultIfEmpty()
group j2 by p.ParentId into grouped
select new { ParentId = grouped.Key, Count = grouped.Count(t=>t.ChildId != null) }

When above problem exists and you have Two Factor Authentication enabled, just do the following:

1. go to http://appleid.apple.com and then create your App-Specific Password

2. Inside Application Loader login with your apple id and App Specific Password you just created.

3. Upload your ipa to itunesconnect.

DateTime.Now is what you're searching for...

You opened a lot of connections and that's the issue. I think in your code, you did not close the opened connection.

A database bounce could temporarily solve, but will re-appear when you do consecutive execution. Also, it should be verified the number of concurrent connections to the database. If maximum DB processes parameter has been reached this is a common symptom.

Except for a few very rare cases (possibly a many-to-many relationship table, or a table you temporarily use for bulk-loading huge amounts of data), I would go with the saying:

If it doesn't have a primary key, it's not a table!

setting aria-hidden to false and toggling it on element.show() worked for me.

e.g

<span aria-hidden="true">aria text</span>

$(span).attr('aria-hidden', 'false');
$(span).show();

and when hiding back

$(span).attr('aria-hidden', 'true');
$(span).hide();
