adding the ":.+" worked for me, but not until I removed outer curly brackets.

value = {"/username/{id:.+}"} didn't work

value = "/username/{id:.+}" works

Hope I helped someone :)

Your problem is that you need a static PropertySourcesPlaceholderConfigurer Bean definition in your configuration. I say static with emphasis, because I had a non-static one and it didn't work.

@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
    return new PropertySourcesPlaceholderConfigurer();
}

In your controller class, just add @ComponentScan("package") annotation. In my case the package name is com.shoppingcart.So i wrote the code as @ComponentScan("com.shoppingcart") and it worked for me.

I like Zakaria's answer, but if you're in a project where your team doesn't want to use that approach, and you're stuck trying to construct something with a String, integer, float, or primative type from a property file into the constructor, then you can use Spring's @Value annotation on the parameter in the constructor.

For example, I had an issue where I was trying to pull a string property into my constructor for a class annotated with @Service. My approach works for @Service, but I think this approach should work with any spring java class, if it has an annotation (such as @Service, @Component, etc.) which indicate that Spring will be the one constructing instances of the class.

Let's say in some yaml file (or whatever configuration you're using), you have something like this:

some:
    custom:
        envProperty: "property-for-dev-environment"

and you've got a constructor:

@Service // I think this should work for @Component, or any annotation saying Spring is the one calling the constructor.
class MyClass {
...
    MyClass(String property){
    ...
    }
...
}

This won't run as Spring won't be able to find the string envProperty. So, this is one way you can get that value:

class MyDynamoTable
import org.springframework.beans.factory.annotation.Value;
...
    MyDynamoTable(@Value("${some.custom.envProperty}) String property){
    ...
    }
...

In the above constructor, Spring will call the class and know to use the String "property-for-dev-environment" pulled from my yaml configuration when calling it.

NOTE: this I believe @Value annotation is for strings, intergers, and I believe primative types. If you're trying to pass custom classes (beans), then approaches in answers defined above work.

Spring Boot do a lot of automatically things to us but when we use the annotation @SpringBootTest we think that everything will be automatically solved by Spring boot.

There are a lot of documentation, but the minimal is to choose one engine (@RunWith(SpringRunner.class)) and indicate the class that will be used create the context to load the configuration (resources/applicationl.properties).

In a simple way you need the engine and the context:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyClassTest .class)
public class MyClassTest {

    @Value("${my.property}")
    private String myProperty;

    @Test
    public void checkMyProperty(){
        Assert.assertNotNull(my.property);
    }
}

Of course, if you look the Spring Boot documentation you will find thousands os ways to do that.

public String create(@Valid @NotNull ScriptFile scriptFile, BindingResult result, ModelMap modelMap) {    
    if (scriptFile == null) throw new IllegalArgumentException("A scriptFile is required");        

I guess this @NotNull annotation is valid therefore if condition is not needed.

To get this working with YAML, do this:

property-name: '{
  key1: "value1",
  key2: "value2"
}'

In MAC, go to Terminal

1) Navigate to Home Directory using command - cd ~

2) cd .ssh && ssh-keygen (For Defaults, click on Enter/Return key for both inputs)

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/username/.ssh/id_rsa):      
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/usernmae/.ssh/id_rsa.

3) After that , Do "ls". you will find id_rsa.pub file.

4) Copy the contents in the id_rsa.pub file (read using the cat command - cat id_rsa.pub)

5) Navigate to BitBucket or any version tool which supports the SSH keys. Paste the contents using the Add Key Option

That's it. Try to commit and push now.

I was using CommonCrypto to generate Hash through the code of MihaelIsaev/HMAC.swift from Easy to use Swift implementation of CommonCrypto HMAC. This implementation is without using Bridging-Header, with creation of Module file.

Now to use AESEncrypt and Decrypt, I directly added the functions inside "extension String {" in HAMC.swift.

func aesEncrypt(key:String, iv:String, options:Int = kCCOptionPKCS7Padding) -> String? {
    if let keyData = key.dataUsingEncoding(NSUTF8StringEncoding),
        data = self.dataUsingEncoding(NSUTF8StringEncoding),
        cryptData    = NSMutableData(length: Int((data.length)) + kCCBlockSizeAES128) {

            let keyLength              = size_t(kCCKeySizeAES128)
            let operation: CCOperation = UInt32(kCCEncrypt)
            let algoritm:  CCAlgorithm = UInt32(kCCAlgorithmAES128)
            let options:   CCOptions   = UInt32(options)

            var numBytesEncrypted :size_t = 0

            let cryptStatus = CCCrypt(operation,
                algoritm,
                options,
                keyData.bytes, keyLength,
                iv,
                data.bytes, data.length,
                cryptData.mutableBytes, cryptData.length,
                &numBytesEncrypted)

            if UInt32(cryptStatus) == UInt32(kCCSuccess) {
                cryptData.length = Int(numBytesEncrypted)
                let base64cryptString = cryptData.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
                return base64cryptString
            }
            else {
                return nil
            }
    }
    return nil
}

func aesDecrypt(key:String, iv:String, options:Int = kCCOptionPKCS7Padding) -> String? {
    if let keyData = key.dataUsingEncoding(NSUTF8StringEncoding),
        data = NSData(base64EncodedString: self, options: .IgnoreUnknownCharacters),
        cryptData    = NSMutableData(length: Int((data.length)) + kCCBlockSizeAES128) {

            let keyLength              = size_t(kCCKeySizeAES128)
            let operation: CCOperation = UInt32(kCCDecrypt)
            let algoritm:  CCAlgorithm = UInt32(kCCAlgorithmAES128)
            let options:   CCOptions   = UInt32(options)

            var numBytesEncrypted :size_t = 0

            let cryptStatus = CCCrypt(operation,
                algoritm,
                options,
                keyData.bytes, keyLength,
                iv,
                data.bytes, data.length,
                cryptData.mutableBytes, cryptData.length,
                &numBytesEncrypted)

            if UInt32(cryptStatus) == UInt32(kCCSuccess) {
                cryptData.length = Int(numBytesEncrypted)
                let unencryptedMessage = String(data: cryptData, encoding:NSUTF8StringEncoding)
                return unencryptedMessage
            }
            else {
                return nil
            }
    }
    return nil
}

The functions were taken from RNCryptor. It was an easy addition in the hashing functions and in one single file "HMAC.swift", without using Bridging-header. I hope this will be useful for developers in swift requiring Hashing and AES Encryption/Decryption.

Example of using the AESDecrypt as under.

 let iv = "AA-salt-BBCCDD--" // should be of 16 characters.
 //here we are convert nsdata to String
 let encryptedString = String(data: dataFromURL, encoding: NSUTF8StringEncoding)
 //now we are decrypting
 if let decryptedString = encryptedString?.aesDecrypt("12345678901234567890123456789012", iv: iv) // 32 char pass key
 {                    
      // Your decryptedString
 }

Pandas uses numpy's NaN value. Use numpy.isnan to obtain a Boolean vector from a pandas series.

There are two competing concerns: with less training data, your parameter estimates have greater variance. With less testing data, your performance statistic will have greater variance. Broadly speaking you should be concerned with dividing data such that neither variance is too high, which is more to do with the absolute number of instances in each category rather than the percentage.

If you have a total of 100 instances, you're probably stuck with cross validation as no single split is going to give you satisfactory variance in your estimates. If you have 100,000 instances, it doesn't really matter whether you choose an 80:20 split or a 90:10 split (indeed you may choose to use less training data if your method is particularly computationally intensive).

Assuming you have enough data to do proper held-out test data (rather than cross-validation), the following is an instructive way to get a handle on variances:

1. Split your data into training and testing (80/20 is indeed a good starting point)
2. Split the training data into training and validation (again, 80/20 is a fair split).
3. Subsample random selections of your training data, train the classifier with this, and record the performance on the validation set
4. Try a series of runs with different amounts of training data: randomly sample 20% of it, say, 10 times and observe performance on the validation data, then do the same with 40%, 60%, 80%. You should see both greater performance with more data, but also lower variance across the different random samples
5. To get a handle on variance due to the size of test data, perform the same procedure in reverse. Train on all of your training data, then randomly sample a percentage of your validation data a number of times, and observe performance. You should now find that the mean performance on small samples of your validation data is roughly the same as the performance on all the validation data, but the variance is much higher with smaller numbers of test samples

Try to change the loop like this:

for line in $(cat filename); do
    read input
    echo $input;
done

Unit test:

for line in $(cat /etc/passwd); do
    read input
    echo $input;
    echo "[$line]"
done

I assigned the javascript in my Controller:

model.linkCode = "window.open('https://www.yahoo.com', '_blank')";

And in my view:

@section Scripts{
    <script @Html.CspScriptNonce()>

    $(function () {

        @if (!String.IsNullOrEmpty(Model.linkCode))
        {
            WriteLiteral(Model.linkCode);
        }
    });

That opened a new tab with the link, and went to it.

Interestingly, run locally it engaged a popup blocker, but seemed to work fine on the servers.

Windows 7 location is: C:\Users\All Users\MySQL\MySQL Server 5.5\my.ini

For XP may be: C:\Documents and Settings\All Users\MySQL\MySQL Server 5.5\my.ini

At the tops of these files are comments defining where my.cnf can be found.

The answer is on the MSDN site:

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column

EDIT 1:

Additional useful informations from here:

To change the Prevent saving changes that require the table re-creation option, follow these steps:

1. Open SQL Server Management Studio (SSMS).
2. On the Tools menu, click Options.
3. In the navigation pane of the Options window, click Designers.
4. Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

Risk of turning off the "Prevent saving changes that require table re-creation" option

Although turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore, we recommend that you do not work around this problem by turning off the option.

Your question isn't very clear. From your own answer, I can tell better what you are trying to do:

public static String[] removeElements(String[] input, String deleteMe) {
    List result = new LinkedList();

    for(String item : input)
        if(!deleteMe.equals(item))
            result.add(item);

    return result.toArray(input);
}

NB: This is untested. Error checking is left as an exercise to the reader (I'd throw IllegalArgumentException if either input or deleteMe is null; an empty list on null list input doesn't make sense. Removing null Strings from the array might make sense, but I'll leave that as an exercise too; currently, it will throw an NPE when it tries to call equals on deleteMe if deleteMe is null.)

Choices I made here:

I used a LinkedList. Iteration should be just as fast, and you avoid any resizes, or allocating too big of a list if you end up deleting lots of elements. You could use an ArrayList, and set the initial size to the length of input. It likely wouldn't make much of a difference.

You could call editText.invalidate() after you reset the hint color. That could resolve your issue. Actually the SDK update the color in the same way.

You can use the following:

1. Type Alias (using type keyword, aliasing a function literal)
2. Interface
3. Function Literal

Here is an example of how to use them:

type myCallbackType = (arg1: string, arg2: boolean) => number;

interface myCallbackInterface { (arg1: string, arg2: boolean): number };

class CallbackTest
{
    // ...

    public myCallback2: myCallbackType;
    public myCallback3: myCallbackInterface;
    public myCallback1: (arg1: string, arg2: boolean) => number;

    // ...

}

you may also like this

var Grp = Model.GroupBy(item => item.Order.Customer)
      .Select(group => new 
        { 
             Customer = Model.First().Customer, 
             CustomerId= group.Key,  
             Orders= group.ToList() 
       })
      .ToList();

Neither one. Use final class for Constants declare them as public static final and static import all constants wherever necessary.

public final class Constants {

    private Constants() {
            // restrict instantiation
    }

    public static final double PI = 3.14159;
    public static final double PLANCK_CONSTANT = 6.62606896e-34;
}

Usage :

import static Constants.PLANCK_CONSTANT;
import static Constants.PI;//import static Constants.*;

public class Calculations {

        public double getReducedPlanckConstant() {
                return PLANCK_CONSTANT / (2 * PI);
        }
}

If you want to use environment variable during build. Lets say setting username and password.

username= Ubuntu
password= swed24sw

Dockerfile

FROM ubuntu:16.04
ARG SMB_PASS
ARG SMB_USER
# Creates a new User
RUN useradd -ms /bin/bash $SMB_USER
# Enters the password twice.
RUN echo "$SMB_PASS\n$SMB_PASS" | smbpasswd -a $SMB_USER

Terminal Command

docker build --build-arg SMB_PASS=swed24sw --build-arg SMB_USER=Ubuntu . -t IMAGE_TAG

First install pillow

pip install pillow

Example

from PIL import Image, ImageDraw, ImageFont

image = Image.open('Focal.png')
width, height = image.size 

draw = ImageDraw.Draw(image)

text = 'https://devnote.in'
textwidth, textheight = draw.textsize(text)

margin = 10
x = width - textwidth - margin
y = height - textheight - margin

draw.text((x, y), text)

image.save('devnote.png')

# optional parameters like optimize and quality
image.save('optimized.png', optimize=True, quality=50)

there are three ways you can use: the RETURN value, and OUTPUT parameter and a result set

ALSO, watch out if you use the pattern: SELECT @Variable=column FROM table ...

if there are multiple rows returned from the query, your @Variable will only contain the value from the last row returned by the query.

RETURN VALUE
since your query returns an int field, at least based on how you named it. you can use this trick:

CREATE PROCEDURE GetMyInt
( @Param int)
AS
DECLARE @ReturnValue int

SELECT @ReturnValue=MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN @ReturnValue
GO

and now call your procedure like:

DECLARE @SelectedValue int
       ,@Param         int
SET @Param=1
EXEC @SelectedValue = GetMyInt @Param
PRINT @SelectedValue

this will only work for INTs, because RETURN can only return a single int value and nulls are converted to a zero.

OUTPUT PARAMETER
you can use an output parameter:

CREATE PROCEDURE GetMyInt
( @Param     int
 ,@OutValue  int OUTPUT)
AS
SELECT @OutValue=MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN 0
GO

and now call your procedure like:

DECLARE @SelectedValue int
       ,@Param         int
SET @Param=1
EXEC GetMyInt @Param, @SelectedValue OUTPUT
PRINT @SelectedValue 

Output parameters can only return one value, but can be any data type

RESULT SET for a result set make the procedure like:

CREATE PROCEDURE GetMyInt
( @Param     int)
AS
SELECT MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN 0
GO

use it like:

DECLARE @ResultSet table (SelectedValue int)
DECLARE @Param int
SET @Param=1
INSERT INTO @ResultSet (SelectedValue)
    EXEC GetMyInt @Param
SELECT * FROM @ResultSet 

result sets can have many rows and many columns of any data type

It means you allow every (*) user-agent/crawler to access the root (/) of your site. You're okay.

You can use:

    select FK_Items,Sum(PoiQuantity) Quantity  from PurchaseOrderItems POI
    left join PurchaseOrder PO ON po.ID_PurchaseOrder=poi.FK_PurchaseOrder
    group by FK_Items,DATEPART(MONTH, TransDate)

<input type="text" style="width:50px;"/>

Try this out:

grep -i 'killed process' /var/log/messages

With Apache Commons Library, you can simply use Stringutils.replaceEach:

public static String replaceEach(String text,
                             String[] searchList,
                             String[] replacementList)

From the documentation:

Replaces all occurrences of Strings within another String.

A null reference passed to this method is a no-op, or if any "search string" or "string to replace" is null, that replace will be ignored. This will not repeat. For repeating replaces, call the overloaded method.

 StringUtils.replaceEach(null, *, *)        = null

  StringUtils.replaceEach("", *, *)          = ""

  StringUtils.replaceEach("aba", null, null) = "aba"

  StringUtils.replaceEach("aba", new String[0], null) = "aba"

  StringUtils.replaceEach("aba", null, new String[0]) = "aba"

  StringUtils.replaceEach("aba", new String[]{"a"}, null)  = "aba"

  StringUtils.replaceEach("aba", new String[]{"a"}, new String[]{""})  = "b"

  StringUtils.replaceEach("aba", new String[]{null}, new String[]{"a"})  = "aba"

  StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"w", "t"})  = "wcte"
  (example of how it does not repeat)

StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"d", "t"})  = "dcte"

Bind variable can be used in Oracle SQL query with "in" clause.

Works in 10g; I don't know about other versions.

Bind variable is varchar up to 4000 characters.

Example: Bind variable containing comma-separated list of values, e.g.

:bindvar = 1,2,3,4,5

select * from mytable
  where myfield in
    (
      SELECT regexp_substr(:bindvar,'[^,]+', 1, level) items
      FROM dual
      CONNECT BY regexp_substr(:bindvar, '[^,]+', 1, level) is not null
    );

(Same info as I posted here: How do you specify IN clause in a dynamic query using a variable? )

You should to use: ConfigurableApplicationContext instead of for ApplicationContext

You actually need to understand the ApplicationContext. It is an interface and it will have different implementations based on configuration.

As you are using new ClassPathXmlApplicationContext("applicationContext.xml"); , kindly pay attention to initial right hand-side , it says ClassPathXmlApplicationContext , so the XML must be present in the class path. So drag your applicationContext.xml wherever it is to the src folder.

Gist: new ClassPathXmlApplicationContext as the name [ClassPathXml]will look for the xml file in the src folder of your project, so drag your xml file there only.

? ClassPathXmlApplicationContext—Loads a context definition from an XML file located in the classpath, treating context definition files as classpath resources.

? FileSystemXmlApplicationContext—Loads a context definition from an XML file in the file system.

? XmlWebApplicationContext—Loads context definitions from an XML file contained within a web application.

Create the data/db directory in your main (windows) partition:

C:\> mkdir \data
C:\> mkdir \data\db

and then go to your mongo_directory/bin and run mongod.exe:

C:\> cd \my_mongo_dir\bin

C:\my_mongo_dir\bin> mongod

DON't CLOSE THIS WINDOW

Now in a different command prompt window run Mongo:

C:\> cd \my_mongo_dir\bin
C:\my_mongo_dir\bin> mongo

(REMEMBER YOU HAVE TO KEEP THAT OTHER WINDOW OPEN)

This solved the problem for me.

console.log() just takes whatever you pass to it and writes it to a console's log window. If you pass in an array, you'll be able to inspect the array's contents. Pass in an object, you can examine the object's attributes/methods. pass in a string, it'll log the string. Basically it's "document.write" but can intelligently take apart its arguments and write them out elsewhere.

It's useful to outputting occasional debugging information, but not particularly useful if you have a massive amount of debugging output.

To watch as a script's executing, you'd use a debugger instead, which allows you step through the code line-by-line. console.log's used when you need to display what some variable's contents were for later inspection, but do not want to interrupt execution.

Ctrl+J works; but also shows/hides the console.

What output (exactly) does dir myfile.txt give in the current directory? What happens if you set the delimiters?

FOR /f "tokens=1,2* delims= " %%a in ('dir myfile.txt^|find /i " myfile.txt"') DO SET fileDate=%%a 

(note the space after delims=)
(to make life easier, you can do this from the command line by replacing %%a with %a)

You could use Java reflection to do this. The method would be represented as an instance of java.lang.reflect.Method.

import java.lang.reflect.Method;

public class Demo {

    public static void main(String[] args) throws Exception{
        Class[] parameterTypes = new Class[1];
        parameterTypes[0] = String.class;
        Method method1 = Demo.class.getMethod("method1", parameterTypes);

        Demo demo = new Demo();
        demo.method2(demo, method1, "Hello World");
    }

    public void method1(String message) {
        System.out.println(message);
    }

    public void method2(Object object, Method method, String message) throws Exception {
        Object[] parameters = new Object[1];
        parameters[0] = message;
        method.invoke(object, parameters);
    }

}

You don't need an array to do it.

var ItemNode = this.state.data.map(function(itemData) {
return (
   <ComponentName title={itemData.title} key={itemData.id} number={itemData.id}/>
 );
});

if you're importing an eclipse project to android studio, you'll also encounter the same issue as above. Double Check if grade>app has apply plugin: 'com.android.application' on the top as sometimes android studio imports it as a library.

As Thrasgod correctly showed in his answer, the best way is to use the paintComponent, but also if the case is to have a semi transparent JPanel (or any other component, really) and have something not transparent inside. You have to also override the paintChildren method and set the alfa value to 1. In my case I extended the JPanel like that:

public class TransparentJPanel extends JPanel {

private float panelAlfa;
private float childrenAlfa;

public TransparentJPanel(float panelAlfa, float childrenAlfa) {
    this.panelAlfa = panelAlfa;
    this.childrenAlfa = childrenAlfa;
}

@Override
public void paintComponent(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.setColor(getBackground());
    g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setComposite(AlphaComposite.getInstance(
            AlphaComposite.SRC_OVER, panelAlfa));
    super.paintComponent(g2d);

}

@Override
protected void paintChildren(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.setColor(getBackground());
    g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setComposite(AlphaComposite.getInstance(
            AlphaComposite.SRC_ATOP, childrenAlfa));
  
    super.paintChildren(g); 
}
 //getter and setter
}

And in my project I only need to instantiate Jpanel jp = new TransparentJPanel(0.3f, 1.0f);, if I want only the Jpanel transparent. You could, also, mess with the JPanel shape using g2d.fillRoundRect and g2d.drawRoundRect, but it's not in the scope of this question.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

your initial request is "I have a large PDF file that is a floor map for a building. "

I am afraid to tell you this might be harder than you guess.

Cause the last known lib everyones use to parse pdf is smalot, and this one is known to encounter issue regarding large file.

Here too, Lookig for a real php lib to parse pdf, without any memory peak that need a php configuration to disable memory limit as lot of "developers" does (which I guess is really not advisable).

see this post for more details about smalot performance : https://github.com/smalot/pdfparser/issues/163

a example:

$('input[name=radioName]:checked', '#myForm').val()_x000D_
$('#myForm input').on('change', function() {_x000D_
 $('#val').text($('input[name=radioName]:checked', '#myForm').val());_x000D_

Just to add another option - if you like/tolerate coffee-script you can use coffee-react to write your JSX in which case if/else statements are usable as they are expressions in coffee-script and not statements:

render: ->
  <div className="container">
    {
      if something
        <h2>Coffeescript is magic!</h2>
      else
        <h2>Coffeescript sucks!</h2>
    }
  </div>  

If a, b are datetime objects then to find the time difference between them in Python 3:

from datetime import timedelta

time_difference = a - b
time_difference_in_minutes = time_difference / timedelta(minutes=1)

On earlier Python versions:

time_difference_in_minutes = time_difference.total_seconds() / 60

If a, b are naive datetime objects such as returned by datetime.now() then the result may be wrong if the objects represent local time with different UTC offsets e.g., around DST transitions or for past/future dates. More details: Find if 24 hrs have passed between datetimes - Python.

To get reliable results, use UTC time or timezone-aware datetime objects.

It is not best practise to mix up content with style, but a solution could be

<div class="thumb" style="background-image: url('images/img.jpg')"></div>

Try setting: "AllowOverride All".

Sometimes it's as simple as adding: '-ms-' in front of the style Like -ms-flex-flow: row wrap; to get it to work also.

If you want to modify your List during traversal, then you need to use the Iterator. And then you can use iterator.remove() to remove the elements during traversal.

This topic, especially the answer of Xotic750 was very helpful to me. I wanted to generate a json variable to pass it to a php script using ajax. My values were stored into two arrays, and i wanted them in json format. This is a generic example:

valArray1 = [121, 324, 42, 31];
valArray2 = [232, 131, 443];
myJson = {objArray1: {}, objArray2: {}};
for (var k = 1; k < valArray1.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray1[k];
    myJson.objArray1[objName] = objValue;
}
for (var k = 1; k < valArray2.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray2[k];
    myJson.objArray2[objName] = objValue;
}
console.log(JSON.stringify(myJson));

The result in the console Log should be something like this:

{
   "objArray1": {
        "obj1": 121,
        "obj2": 324,
        "obj3": 42,
        "obj4": 31
   },
   "objArray2": {
        "obj1": 232,
        "obj2": 131,
        "obj3": 443
  }
}

SOLUTION

As stated by others very well, HTTP_REFERER is set by the local machine of the user, specifically the browser, which means it's not reliable for security. However, this still is entirely the way in which Google Analytics monitors where you're getting your visitors from, so, it can actually be useful to check, exclude, include, etc..

If you think you should see an HTTP_REFERER and do not, add this to your PHP code, preferably at the top:

ini_set('session.referer_check', 'TRUE');

A more appropriate long-term solution, of course, is to actually update your php.ini or equivalent file. This is a nice and quick way of verifying, though.

TESTING

Run print($_SERVER['HTTP_REFERER']); on your site, go to google.com, inspect some text, edit it to be <a href="https://example.com">LINK!</a>, apply the change, then click the link. If it works, all is well and running precisely!

But maybe $_SERVER is wrong, or the test above says it's broken. Update your page with this, and then test again...

<script type="text/javascript">
    console.log("REFER!" + document.referrer + "|" + location.referrer + "|");
</script>

USES

I use HTTP REFERER to block spam sites in GoogleAnalytics. Below is a graph focusing on one particular website's referrals. From 0 to 44 in one day, it wasn't caused by real users. It was caused by a botted site trying to get my attention to buy their services. But it just started because php.ini was updated to ignore the referer, which meant these spam, junk garbage sites were not getting their appropriate ERROR 403, "Access Denied."

Inherit Activity Class instead of ListActivity you can resolve this problem.

public class ExampleActivity extends Activity  {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.mainlist);
    }
}

When compare something with Boolean it works like following

Step 1: Convert boolean to Number Number(true) // 1 and Number(false) // 0

Step 2: Compare both sides

boolean == someting 
-> Number(boolean) === someting

If compare 1 and 2 with true you will get the following results

true == 1
-> Number(true) === 1
-> 1 === 1
-> true

And

true == 2
-> Number(true) === 1
-> 1 === 2
-> false

Sometimes, patience is key.

I had the same problem with a java project with big node_modules / .m2 directories.
The indexing was very long so I paused it and it prevented me from using Run Configurations.

So I waited for the indexing to finish and only then I was able to run my main class.

There is no built-in functions to do that in Php (shame ^^). You want to compare a date string to today, you could use a simple substr to achieve it:

if (substr($timestamp, 0, 10) === date('Y.m.d')) { today }
elseif (substr($timestamp, 0, 10) === date('Y.m.d', strtotime('-1 day')) { yesterday }

No date conversion, simple.

Just add background-attachment to your code

body {
    background-position: center;
    background-image: url(../images/images5.jpg);
    background-attachment: fixed;
}

>>> for i in range(1, 11):
...     print(i, end=' ')
...     if i==len(range(1, 11)): print()
... 
1 2 3 4 5 6 7 8 9 10 
>>> 

This is how to do it so that the printing does not run behind the prompt on the next line.

Using bits of answers from this question and the latest doc, I was able to extract my numerical arrays using

import h5py
with h5py.File(filename, 'r') as h5f:
    h5x = h5f[list(h5f.keys())[0]]['x'][()]

Where 'x' is simply the X coordinate in my case.

To check if a folder exists or not, you can simply use the exists() method:

// Create a File object representing the folder 'A/B'
def folder = new File( 'A/B' )

// If it doesn't exist
if( !folder.exists() ) {
  // Create all folders up-to and including B
  folder.mkdirs()
}

// Then, write to file.txt inside B
new File( folder, 'file.txt' ).withWriterAppend { w ->
  w << "Some text\n"
}

If you don't want to make any changes in your current query then follow the below steps -

1. vagrant ssh into your box
2. Type: sudo vim /etc/mysql/my.cnf
3. Scroll to the bottom of file and type A to enter insert mode

4. Copy and paste

   [mysqld]
   sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
   

5. Type esc to exit input mode

6. Type :wq to save and close vim.
7. Type sudo service mysql restart to restart MySQL.

Ask the user for the exact URL they're using in their browser. If they're entering https://your.site:80, they may receive the ssl_error_rx_record_too_long error.

If you actually want to sort the dictionary instead of just obtaining a sorted list use collections.OrderedDict

>>> from collections import OrderedDict
>>> from operator import itemgetter
>>> data = {1: 'b', 2: 'a'}
>>> d = OrderedDict(sorted(data.items(), key=itemgetter(1)))
>>> d
OrderedDict([(2, 'a'), (1, 'b')])
>>> d.values()
['a', 'b']

The IIS is a multi web site server. The way is distinct the site is by the host header name. So you need to setup that on your web site.

Here is the steps that you need to follow:

How to configure multiple IIS websites to access using host headers?

In general, open your web site properties, locate the Ip Address and near its there is the advanced, "multiple identities for this web site". There you need ether to add all income to this site with a star: "*", ether place the names you like to work with.

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder) as a Spring bean:

For example:

   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
   @Override
   public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
   }

I assume you are on Windows. Instead of trying to run your program by double clicking on it's icon or clicking a button in your IDE, open up a command prompt, cd to the directory your program is in, and run it by typing its name on the command line.

The task must be configured in two steps.

First you create a simple task that start at 0:00, every day. Then, you go in Advanced... (or similar depending on the operating system you are on) and select the Repeat every X minutes option for 24 hours.

The key here is to find the advanced properties. If you are using the XP wizard, it will only offer you to launch the advanced dialog once you created the task.

On more recent versions of Windows (7+ I think?):

1. Double click the task and a property window will show up.
2. Click the Triggers tab.
3. Double click the trigger details and the Edit Trigger window will show up.
4. Under Advanced settings panel, tick Repeat task every xxx minutes, and set Indefinitely if you need.
5. Finally, click ok.

Do aman 2 sendfile. You only need to open the source file on the client and destination file on the server, then call sendfile and the kernel will chop and move the data.

It's simple. Suppose you want to move from A to C

if there's only one disk, just move it.

If there's more than one disk, do

• move all disks (n-1 disks), except the bottom one from A to B
• move the bottom disk from A to C
• move the n-1 disks from the first step from A to C

Keep in mind that, when moving the n-1 disks, the nth won't be a problem at all (once it is bigger than all the others)

Note that moving the n-1 disks recurs on the same problem again, until n-1 = 1, in which case you'll be on the first if (where you should just move it).

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

It should be understood that from a performance standpoint there are no differences between @temp tables and #temp tables that favor variables. They reside in the same place (tempdb) and are implemented the same way. All the differences appear in additional features. See this amazingly complete writeup: https://dba.stackexchange.com/questions/16385/whats-the-difference-between-a-temp-table-and-table-variable-in-sql-server/16386#16386

Although there are cases where a temp table can't be used such as in table or scalar functions, for most other cases prior to v2016 (where even filtered indexes can be added to a table variable) you can simply use a #temp table.

The drawback to using named indexes (or constraints) in tempdb is that the names can then clash. Not just theoretically with other procedures but often quite easily with other instances of the procedure itself which would try to put the same index on its copy of the #temp table.

To avoid name clashes, something like this usually works:

declare @cmd varchar(500)='CREATE NONCLUSTERED INDEX [ix_temp'+cast(newid() as varchar(40))+'] ON #temp (NonUniqueIndexNeeded);';
exec (@cmd);

This insures the name is always unique even between simultaneous executions of the same procedure.

Try this:

window.location.href = "http://PlaceYourUrl.com";

This post helped me A LOT!

I added UIViewAlertForUnsatisfiableConstraints symbolic breakpoint with suggested action:

Obj-C project

po [[UIWindow keyWindow] _autolayoutTrace]

Swift project

expr -l objc++ -O -- [[UIWindow keyWindow] _autolayoutTrace]

With this hint, the log became more detailed, and It was easier for me identify which view had the constraint broken.

Then I paused execution and I changed problematic view's background color with the command (replacing 0x7f88a8cc2050 with the memory address of your object of course)...

Obj-C

expr ((UIView *)0x7f88a8cc2050).backgroundColor = [UIColor redColor]

Swift 3.0

expr -l Swift -- import UIKit
expr -l Swift -- unsafeBitCast(0x7f88a8cc2050, to: UIView.self).backgroundColor = UIColor.red

... and the result It was awesome!

Simply amazing! Hope It helps.

I found that when I was reading strings in from a .plist file, occurrences of "\n" were parsed as "\\n". The solution for me was to replace occurrences of "\\n" with "\n". For example, given an instance of NSString named myString read in from my .plist file, I had to call...

myString = [myString stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"];

... before assigning it to my UILabel instance...

myLabel.text = myString;

I used the RowHeight property of a range (which means cells as well). If it's zero then it's hidden. So just loop through all rows as you would normally but in the if condition check for that property as in If myRange.RowHeight > 0 then DoStuff where DoStuff is something you want to do with the visible cells.

I had the very same issue, not being able to instantiate the type of a class which I was absolutely sure was not abstract. Turns out I was implementing an abstract class from Java.util instead of implementing my own class.

So if the previous answers did not help you, please check that you import the class you actually wanted to import, and not something else with the same name that you IDE might have hinted you.

For example, if you were trying to instantiate the class Queue from the package myCollections which you coded yourself :

import java.util.*; // replace this line
import myCollections.Queue; // by this line

     Queue<Edge> theQueue = new Queue<Edge>();

I think you need to include only these options in build.gradle:

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }

p.s same answer from my post in : Error :: duplicate files during packaging of APK

You can also use info files to list all the sections of all the binaries loaded in process binary.

If you want to know this, it exists an open source library called aFileDialog that it is an small and easy to use which provides a file picker.

The difference with another file chooser's libraries for Android is that aFileDialog gives you the option to open the file chooser as a Dialog and as an Activity.

It also lets you to select folders, create files, filter files using regular expressions and show confirmation dialogs.

start "" ExeToExecute

method does not work for me in the case of Xilinx xsdk, because as pointed out by @jeb in the comments below it is actaully a bat file.

so what does not work de-facto is

start "" BatToExecute

I am trying to open xsdk like that and it opens a separate cmd that needs to be closed and xsdk can run on its own

Before launching xsdk I run (source) the Env / Paths (with settings64.bat) so that xsdk.bat command gets recognized (simply as xsdk, withoitu the .bat)

what works with .bat

call BatToExecute

Try this:

var scrollHeight = $(scrollable)[0] == document ? document.body.scrollHeight : $(scrollable)[0].scrollHeight;

Another alternative:

:call cursor('.',strwidth(getline('.')))

This is may be useful if you're writing a function. Another situation would be when I need to open a specific template and jump to end of first line, I can do:

vi +"call cursor('.',strwidth(getline(1)))"  notetaking_template.txt

The above could also be done with

vi +"execute ':normal! $'" notetaking_template.txt

In response to your postscript, that depends on what you would like.

You are getting (possible) multiple rows for each row in your left table because there are multiple matches for the join condition. If you want your total results to have the same number of rows as there is in the left part of the query you need to make sure your join conditions cause a 1-to-1 match.

Alternatively, depending on what you actually want you can use aggregate functions (if for example you just want a string from the right part you could generate a column that is a comma delimited string of the right side results for that left row.

If you are only looking at 1 or 2 columns from the outer join you might consider using a scalar subquery since you will be guaranteed 1 result.

There is a buffer limit of something like 1024. The read will simply hang mid paste or input. To solve this use the -e option.

http://linuxcommand.org/lc3_man_pages/readh.html

-e use Readline to obtain the line in an interactive shell

Change your read to read -e and annoying line input hang goes away.

It is better to always check with the library you are using if it supports usage in a non-blocking way.

But if you want a more generic solution, or if there is no other way, you can run anything that blocks in a separated process by using the multprocessing module included in python. Computation will continue:

from multiprocessing import Process
from matplotlib.pyplot import plot, show

def plot_graph(*args):
    for data in args:
        plot(data)
    show()

p = Process(target=plot_graph, args=([1, 2, 3],))
p.start()

print 'yay'
print 'computation continues...'
print 'that rocks.'

print 'Now lets wait for the graph be closed to continue...:'
p.join()

That has the overhead of launching a new process, and is sometimes harder to debug on complex scenarios, so I'd prefer the other solution (using matplotlib's nonblocking API calls)

You can use

• helpers.<helper> in Rails 5+ (or ActionController::Base.helpers.<helper>)
• view_context.<helper> (Rails 4 & 3) (WARNING: this instantiates a new view instance per call)
• @template.<helper> (Rails 2)
• include helper in a singleton class and then singleton.helper
• include the helper in the controller (WARNING: will make all helper methods into controller actions)

Inject the request object into the controller using Laravel's magic injection and then access the function non-statically. Laravel will automatically inject concrete dependencies into autoloaded classes

class MyController() 
{

   protected $request;

   public function __construct(\Illuminate\Http\Request $request)
   {
       $this->request = $request;
   }

   public function myFunc()
   {
       $input = $this->request->all();
   }

}

You can do it with an UPDATE statement setting the value with a REPLACE

UPDATE
    Table
SET
    Column = Replace(Column, 'find value', 'replacement value')
WHERE
    xxx

You will want to be extremely careful when doing this! I highly recommend doing a backup first.

vector<char> vec;
//fill the vector;
std::string s(vec.begin(), vec.end());

You didn't specify what the error you're seeing is.

Is the problem that gcc is giving you an error, or that you can't run gcc at all?

If it's the latter, the most likely explanation is that you didn't check "UNIX Development Support" when you installed the development tools, so the command-line executables aren't installed in your path. Re-install the development tools, and make sure to click "customize" and check that box.

This solution WORKS , I had the same issue and after hours I came up to this:

(1) Go to your pom.xml

(2) Add this Dependency :

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>

(3) Run your Project

You want to use "multiline".

$string =~ /(START)(.+?)(END)/m;

For those of you who want an easy solution, do the following in the text Label input box in Interface Builder:

Make sure your number of lines is set to 0.

Alt + Enter

(Alt is your option key)

Cheers!

I set up a simple 3-column range on Sheet1 with Country, City, and Language in columns A, B, and C. The following code autofilters the range and then pastes only one of the columns of autofiltered data to another sheet. You should be able to modify this for your purposes:

Sub CopyPartOfFilteredRange()
    Dim src As Worksheet
    Dim tgt As Worksheet
    Dim filterRange As Range
    Dim copyRange As Range
    Dim lastRow As Long

    Set src = ThisWorkbook.Sheets("Sheet1")
    Set tgt = ThisWorkbook.Sheets("Sheet2")

    ' turn off any autofilters that are already set
    src.AutoFilterMode = False

    ' find the last row with data in column A
    lastRow = src.Range("A" & src.Rows.Count).End(xlUp).Row

    ' the range that we are auto-filtering (all columns)
    Set filterRange = src.Range("A1:C" & lastRow)

    ' the range we want to copy (only columns we want to copy)
    ' in this case we are copying country from column A
    ' we set the range to start in row 2 to prevent copying the header
    Set copyRange = src.Range("A2:A" & lastRow)

    ' filter range based on column B
    filterRange.AutoFilter field:=2, Criteria1:="Rio de Janeiro"

    ' copy the visible cells to our target range
    ' note that you can easily find the last populated row on this sheet
    ' if you don't want to over-write your previous results
    copyRange.SpecialCells(xlCellTypeVisible).Copy tgt.Range("A1")

End Sub

Note that by using the syntax above to copy and paste, nothing is selected or activated (which you should always avoid in Excel VBA) and the clipboard is not used. As a result, Application.CutCopyMode = False is not necessary.

You can use this method to create hidden text field with/without form. If you need form just pass form with object status = true.

You can also add multiple hidden fields. Use this way:

CustomizePPT.setHiddenFields( 
    { 
        "hidden" : 
        {
            'fieldinFORM' : 'thisdata201' , 
            'fieldinFORM2' : 'this3' //multiple hidden fields
            .
            .
            .
            .
            .
            'nNoOfFields' : 'nthData'
        },
    "form" : 
    {
        "status" : "true",
        "formID" : "form3"
    } 
} );

.dmp files are dumps of oracle databases created with the "exp" command. You can import them using the "imp" command.

If you have an oracle client intalled on your machine, you can executed the command

imp help=y

to find out how it works. What will definitely help is knowing from wich schema the data was exported and what the oracle version was.

This will help you.

Javascript

debugger;
var today = new Date();
document.getElementById('date').innerHTML = today

Fiddle Demo

The CSS content property along with ::after and ::before pseudo-elements have been introduced for this.

.item:hover a p.new-label:after{
    content: 'ADD';
}

JSFiddle Demo

if you want the color to change when you have simply add the :hover pseudo

div.e:hover {
    background-color:red;
}

Update 2019 - Bootstrap 4

I'm revisiting this Bootstrap customization question for 4.x, which now utilizes SASS instead of LESS. In general, there are 2 ways to customize Bootstrap...

1. Simple CSS Overrides

One way to customize is simply using CSS to override Bootstrap CSS. For maintainability, CSS customizations are put in a separate custom.css file, so that the bootstrap.css remains unmodified. The reference to the custom.css follows after the bootstrap.css for the overrides to work...

<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
<link rel="stylesheet" type="text/css" href="css/custom.css">

Just add whatever changes are needed in the custom CSS. For example...

    /* remove rounding from cards, buttons and inputs */
    .card, .btn, .form-control {
        border-radius: 0;
    }

Before (bootstrap.css)

After (with custom.css)

When making customizations, you should understand CSS Specificity. Overrides in the custom.css need to use selectors that are the same specificity as (or more specific) the bootstrap.css.

Note there is no need to use !important in the custom CSS, unless you're overriding one of the Bootstrap Utility classes. CSS specificity always works for one CSS class to override another.

2. Customize using SASS

If you're familiar with SASS (and you should be to use this method), you can customize Bootstrap with your own custom.scss. There is a section in the Bootstrap docs that explains this, however the docs don't explain how to utilize existing variables in your custom.scss. For example, let's change the body background-color to #eeeeee, and change/override the blue primary contextual color to Bootstrap's $purple variable...

/* custom.scss */    

/* import the necessary Bootstrap files */
@import "bootstrap/functions";
@import "bootstrap/variables";

/* -------begin customization-------- */   

/* simply assign the value */ 
$body-bg: #eeeeee;

/* use a variable to override primary */
$theme-colors: (
  primary: $purple
);
/* -------end customization-------- */  

/* finally, import Bootstrap to set the changes! */
@import "bootstrap";

This also works to create new custom classes. For example, here I add purple to the theme colors which creates all the CSS for btn-purple, text-purple, bg-purple, alert-purple, etc...

/* add a new purple custom color */
$theme-colors: (
  purple: $purple
);

https://www.codeply.com/go/7XonykXFvP

With SASS you must @import bootstrap after the customizations to make them work! Once the SASS is compiled to CSS (this must be done using a SASS compiler node-sass, gulp-sass, npm webpack, etc..), the resulting CSS is the customized Bootstrap. If you're not familiar with SASS, you can customize Bootstrap using a tool like this theme builder I created.

Custom Bootstrap Demo (SASS)

Note: Unlike 3.x, Bootstrap 4.x doesn't offer an official customizer tool. You can however, download the grid only CSS or use another 4.x custom build tool to re-build the Bootstrap 4 CSS as desired.

If you have reason to avoid the use of the datetime module, then these functions will work.

def is_leap_year(year):
    """ if year is a leap year return True
        else return False """
    if year % 100 == 0:
        return year % 400 == 0
    return year % 4 == 0

def doy(Y,M,D):
    """ given year, month, day return day of year
        Astronomical Algorithms, Jean Meeus, 2d ed, 1998, chap 7 """
    if is_leap_year(Y):
        K = 1
    else:
        K = 2
    N = int((275 * M) / 9.0) - K * int((M + 9) / 12.0) + D - 30
    return N

def ymd(Y,N):
    """ given year = Y and day of year = N, return year, month, day
        Astronomical Algorithms, Jean Meeus, 2d ed, 1998, chap 7 """    
    if is_leap_year(Y):
        K = 1
    else:
        K = 2
    M = int((9 * (K + N)) / 275.0 + 0.98)
    if N < 32:
        M = 1
    D = N - int((275 * M) / 9.0) + K * int((M + 9) / 12.0) + 30
    return Y, M, D

Another possible reason for this error is that you have entire rows duplicated. If that is the case, the problem is solved by removing the duplicate rows.

You should be able to get it to hide/show by setting:

.style.display = 'none';
.style.display = 'inline';

First of all go to the device manager now go to View>>select Show hidden devices....Then go to network adapters and find out Microsoft Hosted network Virual Adapter ....Press right click and enable the option....

Then go to command prompt with administrative privileges and enter the following commands:

netsh wlan set hostednetwork mode=allow
netsh wlan start hostednetwork

Your Hostednetwork will work without any problems.

If you need a simple, more text-oriented documentation of your XSD, check out xs3p - a XSLT stylesheet that will transform your XSD into more readable HTML format. Quite nice, and totally free.

If that's not enough, check out some of the commercial tools out there - I personally prefer the Liquid XML Studio - not as expensive as others, and quite as capable!

This technique is usually used for multiple axis in a figure. In this context it is often required to have a colorbar that corresponds in size with the result from imshow. This can be achieved easily with the axes grid tool kit:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
divider = make_axes_locatable(ax)
cax = divider.append_axes('right', size='5%', pad=0.05)

im = ax.imshow(data, cmap='bone')

fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

My solution is simplier and checked on Ruby 2.0. It also enable download Json. (run CMD.exe as administrator)

    C:\RubyDev>devkitvars.bat
    Adding the DevKit to PATH...

And then write again gem command.

You can drop the range(len()):

weights_h = [[random.random() for e in inputs[0]] for e in range(hiden_neurons)]

But really, you should probably use numpy.

In [9]: numpy.random.random((3, 3))
Out[9]:
array([[ 0.37052381,  0.03463207,  0.10669077],
       [ 0.05862909,  0.8515325 ,  0.79809676],
       [ 0.43203632,  0.54633635,  0.09076408]])

The problem in your code is that you want to apply the operation on every row. The way you've written it though takes the whole 'bar' and 'foo' columns, converts them to strings and gives you back one big string. You can write it like:

df.apply(lambda x:'%s is %s' % (x['bar'],x['foo']),axis=1)

It's longer than the other answer but is more generic (can be used with values that are not strings).

I'd rather do something like this:

private final static String TAG_FRAGMENT = "TAG_FRAGMENT";

private void showFragment() {
    final Myfragment fragment = new MyFragment();
    final FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
    transaction.replace(R.id.fragment, fragment, TAG_FRAGMENT);
    transaction.addToBackStack(null);
    transaction.commit();
}

@Override
public void onBackPressed() {
    final Myfragment fragment = (Myfragment) getSupportFragmentManager().findFragmentByTag(TAG_FRAGMENT);

    if (fragment.allowBackPressed()) { // and then you define a method allowBackPressed with the logic to allow back pressed or not
        super.onBackPressed();
    }
}

This is short, yet efficient and proven approach:

location ~ (patternOne|patternTwo){ #rules etc. }

So one can easily have multiple patterns with simple pipe syntax pointing to the same location block / rules.

Check this:

hello.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View paramView) {
        text.setText("hello");
    }
});

I followed these instructions but then found that the menu hover color was wrong.

I am using the Spacegray theme in Sublime 3 beta 3074. So to accomplish the sidebar font color change and also hover color change, on OSX, I created a new file ~/Library/"Application Support"/"Sublime Text 3"/Packages/User/Spacegray.sublime-theme

then added this code to it:

[
    {
        "class": "sidebar_label",
        "color": [192,197,203],
        "font.bold": false,
        "font.size": 15
    },
     {
        "class": "sidebar_label",
        "parents": [{"class": "tree_row","attributes": ["hover"]}],
        "color": [255,255,255] 
    },
]

It is possible to tweak many other settings for your theme if you can see the original default:

https://gist.github.com/nateflink/0355eee823b89fe7681e

I extracted this file from the sublime package zip file by installing the PackageResourceViewer following MattDMo's instructions (https://stackoverflow.com/users/1426065/mattdmo) here:

Kotlin way

editText.setOnFocusChangeListener { _, hasFocus ->
    if (!hasFocus) {  }
}

Taking Chetan Kumar solution and in case you need to apply to a map[string]int

package main

import (
    "fmt"
    "reflect"
)

type BaseStats struct {
    Hp           int
    HpMax        int
    Mp           int
    MpMax        int
    Strength     int
    Speed        int
    Intelligence int
}

type Stats struct {
    Base map[string]int
    Modifiers []string
}

func StatsCreate(stats BaseStats) Stats {
    s := Stats{
        Base: make(map[string]int),
    }

    //Iterate through the fields of a struct
    v := reflect.ValueOf(stats)
    typeOfS := v.Type()

    for i := 0; i< v.NumField(); i++ {
        val := v.Field(i).Interface().(int)
        s.Base[typeOfS.Field(i).Name] = val
    }
    return s
}

func (s Stats) GetBaseStat(id string) int {
    return s.Base[id]
}


func main() {
    m := StatsCreate(BaseStats{300, 300, 300, 300, 10, 10, 10})

    fmt.Println(m.GetBaseStat("Hp"))
}

there's a bootstrap function to change the color of table header called thead-dark for dark background of table header and thead-light for light background of table header. Your code will look like this after using this function.

<table class="table">
    <tr class="thead-danger">
        <!-- here I used dark table headre -->
        <th>
            @Html.DisplayNameFor(model => model.name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.checkBox1)
        </th>
        <th></th>
    </tr>

Through the original question is not exactly about the locale itself all other locale related questions are referencing to this one. That's why I wanted to clarify the issue here. I used this question as a starting point for my own locale switching code and found out that the method is not exactly correct. It works, but only until any configuration change (e.g. screen rotation) and only in that particular Activity. Playing with a code for a while I have ended up with the following approach:

I have extended android.app.Application and added the following code:

public class MyApplication extends Application
{
    private Locale locale = null;

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        if (locale != null)
        {
            newConfig.locale = locale;
            Locale.setDefault(locale);
            getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
        }
    }

    @Override
    public void onCreate()
    {
        super.onCreate();

        SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);

        Configuration config = getBaseContext().getResources().getConfiguration();

        String lang = settings.getString(getString(R.string.pref_locale), "");
        if (! "".equals(lang) && ! config.locale.getLanguage().equals(lang))
        {
            locale = new Locale(lang);
            Locale.setDefault(locale);
            config.locale = locale;
            getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
        }
    }
}

This code ensures that every Activity will have custom locale set and it will not be reset on rotation and other events.

I have also spent a lot of time trying to make the preference change to be applied immediately but didn't succeed: the language changed correctly on Activity restart, but number formats and other locale properties were not applied until full application restart.

Changes to AndroidManifest.xml

Don't forget to add android:configChanges="layoutDirection|locale" to every activity at AndroidManifest, as well as the android:name=".MyApplication" to the <application> element.

This work for me

Demo: jsfiddle

$(function() 
{
    Fixed_Header();
});

function Fixed_Header()
{
    $('.User_Table thead').css({'position': 'absolute'});
    $('.User_Table tbody tr:eq("2") td').each(function(index,e){
        $('.User_Table thead tr th:eq("'+index+'")').css({'width' : $(this).outerWidth() +"px" });
    });
    var Header_Height = $('.User_Table thead').outerHeight();
    $('.User_Table thead').css({'margin-top' : "-"+Header_Height+"px"});
    $('.User_Table').css({'margin-top' : Header_Height+"px"});
}

You may drag'n'drop your folder to Side bar. To enable Side bar you should do View -> Side bar -> show opened files. You'll got opened files (tabs) tree and folder structure at Side bar.

Just to expand a little... You can execute code directly in the setTimeout call, but as @patrick says, you normally assign a callback function, like this. The time is milliseconds

setTimeout(func, 4000);
function func() {
    alert('Do stuff here');
}

In SQL Server Management Studio, go to Object Explorer > (your server) > Security > Logins and right-click New Login:

Then in the dialog box that pops up, pick the types of objects you want to see (Groups is disabled by default - check it!) and pick the location where you want to look for your objects (e.g. use Entire Directory) and then find your AD group.

You now have a regular SQL Server Login - just like when you create one for a single AD user. Give that new login the permissions on the databases it needs, and off you go!

Any member of that AD group can now login to SQL Server and use your database.

I figured an another solution out, perhaps anyone can use it, too.

string batchContent = "/c \"@ECHO OFF & timeout /t 6 > nul & start \"\" \"$[APPPATH]$\" & exit\"";
batchContent = batchContent.Replace("$[APPPATH]$", Application.ExecutablePath);
Process.Start("cmd", batchContent);
Application.Exit();

Code is simplified so take care of Exceptions and stuff ;)

Example for Transaction

begin tran tt

Your sql statements

if error occurred rollback tran tt else commit tran tt

As long as you have not executed commit tran tt , data will not be changed

Programs that prompt for passwords usually set the tty into "raw" mode, and read input directly from the tty. If you spawn the subprocess in a pty you can make that work. That is what Expect does...

this step works on me : 1. Remove your project on eclipse 2. Re import project 3. Delete target folder on your project 4. mvn or mvnw install

For OS X you can use Charles, it's simple and easy to use.

For more information, please have a look at Android Emulator and Charles Proxy blog post.

I think assembly plugin puts the file on class path. The location will be different in in the JAR than you see on disk. Unpack the resulting JAR and look where the file is located there.

I had the same problem with Visual Studio 2015 and Resharper 9.2

"Resharper 9 keyboard shortcuts not working in Visual Studio 2015"

I had tried all possible resetting and applying keyboard schemes and found the answer from Yuri Fedoseev.

My Windows 10 language configuration only had Swedish in the language preferences "Control Panel\Clock, Language, and Region\Language"

The solution was to add English(I chose the US version) in the language list. And then go to Resharper > Options > Keyboard & Menus > Apply Scheme. (perhaps you do not even need to apply the scheme)

Use Func<T> rather than Action<T>.

Action<T> acts like a void method with parameter of type T, while Func<T> works like a function with no parameters and which returns an object of type T.

If you wish to give parameters to your function, use Func<TParameter1, TParameter2, ..., TReturn>.

Try this one:
Add itemizedOverlay class:

public class AndroidGoogleMapsActivity extends MapActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Displaying Zooming controls
        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);


        MapController mc = mapView.getController();
        double lat = Double.parseDouble("48.85827758964043");
        double lon = Double.parseDouble("2.294543981552124");
        GeoPoint geoPoint = new GeoPoint((int)(lat * 1E6), (int)(lon * 1E6));
        mc.animateTo(geoPoint);
        mc.setZoom(15);
        mapView.invalidate(); 


        /**
         * Placing Marker
         * */
        List<Overlay> mapOverlays = mapView.getOverlays();
        Drawable drawable = this.getResources().getDrawable(R.drawable.mark_red);
        AddItemizedOverlay itemizedOverlay = 
             new AddItemizedOverlay(drawable, this);


        OverlayItem overlayitem = new OverlayItem(geoPoint, "Hello", "Sample Overlay item");

        itemizedOverlay.addOverlay(overlayitem);
        mapOverlays.add(itemizedOverlay);

    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }
}

You could override the toString() method for each enum value.

Example:

public enum Country {

  DE {
    @Override
    public String toString() {
      return "Germany";
    }
  },
  IT {
    @Override
    public String toString() {
      return "Italy";
    }
  },
  US {
    @Override
    public String toString() {
      return "United States";
    }
  }

}

Usage:

public static void main(String[] args) {
  System.out.println(Country.DE); // Germany
  System.out.println(Country.IT); // Italy
  System.out.println(Country.US); // United States
}

using Array Reduce function will get/set based on path provided.

i tested it with a.b.c and a.b.2.c {a:{b:[0,1,{c:7}]}} and its works for both getting key or mutating object to set value

cheerz

    function setOrGet(obj, path=[], newValue){
      const l = typeof path === 'string' ? path.split('.') : path;
      return l.reduce((carry,item, idx)=>{
       const leaf = carry[item];
       
       // is this last item in path ? cool lets set/get value
       if( l.length-idx===1)  { 
         // mutate object if newValue is set;
         carry[item] = newValue===undefined ? leaf : newValue;
         // return value if its a get/object if it was a set
         return newValue===undefined ? leaf : obj ;
       }
    
       carry[item] = leaf || {}; // mutate if key not an object;
       return carry[item]; // return object ref: to continue reduction;
      }, obj)
    }
    
   
    console.log(
     setOrGet({a: {b:1}},'a.b') === 1 ||
    'Test Case: Direct read failed'
    )
    
    console.log(
     setOrGet({a: {b:1}},'a.c',22).a.c===22 ||
    'Test Case: Direct set failed'
    )
    
    console.log(
     setOrGet({a: {b:[1,2]}},'a.b.1',22).a.b[1]===22 ||
    'Test Case: Direct set on array failed'
    )
    
    console.log(
     setOrGet({a: {b:{c: {e:1} }}},'a.b.c.e',22).a.b.c. e===22 ||
    'Test Case: deep get failed'
    )
    
    // failed !. Thats your homework :) 
    console.log(
     setOrGet({a: {b:{c: {e:[1,2,3,4,5]} }}},'a.b.c.e.3 ',22)
    )
    
    
    
    

my personal recommendation.

do not use such a thing unless there is no other way!

i saw many examples people use it for translations for example from json; so you see function like locale('app.homepage.welcome') . this is just bad. if you already have data in an object/json; and you know path.. then just use it directly example locale().app.homepage.welcome by changing you function to return object you get typesafe, with autocomplete, less prone to typo's ..

Honestly, I like the other answers. Easy and no need to get into JS. But I noticed that you were asking about jQuery. So for the sake of completeness, in jQuery if you return false with the .click() handler, it will negate the default action of the widget.

See here for an example (and more goodies, too). Here's the documentation, too.

in a nutshell, with your sample code, do this:

<script type="text/javascript">
    $('button[type!=submit]').click(function(){
        // code to cancel changes
        return false;
    });
</script>

<a href="index.html"><button>Cancel changes</button></a>
<button type="submit">Submit</button>

As an added benefit, with this, you can get rid of the anchor tag and just use the button.

Instead of using string interpolation you could simply format the DateTime using the ToString("u") method and concatenate that with the rest of the string:

$startTime = Get-Date
Write-Host "The script was started " + $startTime.ToString("u") 

fs.readFile takes a call back which calls response.send as you have shown - good. If you simply replace that with fs.readFileSync, you need to be aware it does not take a callback so your callback which calls response.send will never get called and therefore the response will never end and it will timeout.

You need to show your readFileSync code if you're not simply replacing readFile with readFileSync.

Also, just so you're aware, you should never call readFileSync in a node express/webserver since it will tie up the single thread loop while I/O is performed. You want the node loop to process other requests until the I/O completes and your callback handling code can run.

After some trial and error and observing the results (in other words, I hacked it), I got it to work.

Quotes ARE required to use a path name with spaces. The trick is there MUST be a space after the path names before the closing quote...like this...

robocopy "C:\Source Path " "C:\Destination Path " /option1 /option2...

This almost seems like a bug and certainly not very intuitive.

You can use Eclipse DDMS perspective to see connected devices and browse through files, you can also pull and push files to the device. You can also do a bunch of stuff using DDMS, this link explains a little bit more of DDMS uses.

EDIT:

If you just want to copy a database you can locate the database on eclipse DDMS file explorer, select it and then pull the database from the device to your computer.

i've tried all those methods but it didn't work then a workmate told me that Putty Key Generator used to generate keys with 1024 bits but now Putty generate 2048 bits keys by default , so you just need to change the "Number of bits in a generated key" and it should work.

I recommended using SingleThread because you do not have to kill it after using. Also, "stop()" method is deprecated in Kotlin language.

private fun mDoThisJob(){

    Executors.newSingleThreadScheduledExecutor().scheduleAtFixedRate({
        //TODO: You can write your periodical job here..!

    }, 1, 1, TimeUnit.SECONDS)
}

Moreover, you can use it for periodical job. It is very useful. If you would like to do job for each second, you can set because parameters of it:

Executors.newSingleThreadScheduledExecutor().scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit);

TimeUnit values are: NANOSECONDS, MICROSECONDS, MILLISECONDS, SECONDS, MINUTES, HOURS, DAYS.

Follow the below steps it will helps you.

step 1: Go to to your site root folder and you can find the .htaccess file there. Open it with a text editor and find the line #RewriteBase /magento/. Just replace it with #RewriteBase / take out just the 'magento/'

step 2: Then go to your admin panel and enable the Rewrites(set yes for Use Web Server Rewrites). You can find it at System->Configuration->Web->Search Engine Optimization.

step 3: Then go to Cache management page (system cache management ) and refresh your cache and refresh to check the site.

Just use the following code in your javaScript:

if(new Date(hireDate).getTime() > new Date().getTime())
{
//Date greater than today's date 
}

Change the condition according to your requirement.Here is one link for comparision compare in java script

<button id="btnSave" class="btn btn-info">Save</button>

Just add this:

$("#btnSave").prop('disabled', true);

and you will get this which will disable button

<button id="btnSave" class="btn btn-primary" disabled>Save</button>

you can get value of checkbox and status by

$('.i-checks').on('ifChanged', function(event) {
    alert('checked = ' + event.target.checked);
    alert('value = ' + event.target.value);
});

I would read the bytes one by one, and combine them into a long value. That way you control the endianness, and the communication process is transparent.

This will work:

>>> t = [1,1,2,2,3,3,4,5]
>>> print list(set(t))
[1,2,3,4,5]

However, if you have used "list" or "set" as a variable name you will get the:

TypeError: 'set' object is not callable

eg:

>>> set = [1,1,2,2,3,3,4,5]
>>> print list(set(set))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable

Same error will occur if you have used "list" as a variable name.

Way easier than most all of the proposed answers

tslMode.Image = global::ProjectName.Properties.Resources.ImageName;

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

Example:

perfdb-# \df information_schema.*;

List of functions
        Schema      |        Name        | Result data type | Argument data types |  Type  
 information_schema | _pg_char_max_length   | integer | typid oid, typmod integer | normal
 information_schema | _pg_char_octet_length | integer | typid oid, typmod integer | normal
 information_schema | _pg_datetime_precision| integer | typid oid, typmod integer | normal
 .....
 information_schema | _pg_numeric_scale     | integer | typid oid, typmod integer | normal
 information_schema | _pg_truetypid         | oid     | pg_attribute, pg_type     | normal
 information_schema | _pg_truetypmod        | integer | pg_attribute, pg_type     | normal
(11 rows)

Python does not have a defined entry point like Java, C, C++, etc. Rather it simply executes a source file line-by-line. The if statement allows you to create a main function which will be executed if your file is loaded as the "Main" module rather than as a library in another module.

To be clear, this means that the Python interpreter starts at the first line of a file and executes it. Executing lines like class Foobar: and def foobar() creates either a class or a function and stores them in memory for later use.

It worked for me. Go to Tools-> Options -> Debugger -> Native and check the Load DLL exports. Hope this helps

You can use CSS position: sticky; for the first row of the table MDN ref:

.table-class tr:first-child>td{
    position: sticky;
    top: 0;
}

You can also get the text resize events, and the zoom factor by injecting a div containing at least a non-breakable space (possibly, hidden), and regularly checking its height. If the height changes, the text size has changed, (and you know how much - this also fires, incidentally, if the window gets zoomed in full-page mode, and you still will get the correct zoom factor, with the same height / height ratio).

Add span on each or group of words you want to align left or right. then add id or class on the span such as:

<h3>
<span id = "makeLeft"> Left Text</span>
<span id = "makeRight"> Right Text</span>
</h3>

CSS-

#makeLeft{
float: left;
}

#makeRight{
float: right;
}

$sql = "SELECT * FROM MY_TABLE";
$result = mysqli_query($conn, $sql); // First parameter is just return of "mysqli_connect()" function
echo "<br>";
echo "<table border='1'>";
while ($row = mysqli_fetch_assoc($result)) { // Important line !!! Check summary get row on array ..
    echo "<tr>";
    foreach ($row as $field => $value) { // I you want you can right this line like this: foreach($row as $value) {
        echo "<td>" . $value . "</td>"; // I just did not use "htmlspecialchars()" function. 
    }
    echo "</tr>";
}
echo "</table>";

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

I find the most perfectly working answer is this

.noBorder {
    border: 0px;
    padding:0; 
    margin:0;
    border-collapse: collapse;
}

I think this is the culprit:

cmd = new SqlCommand(query, con);

DataTable dt = Select(query);

cmd.ExecuteNonQuery();

ddtype.DataSource = dt;

I don't know what that code is supposed to do, but it looks like you want to create an SqlDataReader for that, as explained here and all over the web if you search for "SqlCommand DropDownList DataSource":

cmd = new SqlCommand(query, con);
ddtype.DataSource = cmd.ExecuteReader();

Or you can create a DataTable as explained here:

cmd = new SqlCommand(query, con);

SqlDataAdapter listQueryAdapter = new SqlDataAdapter(cmd);
DataTable listTable = new DataTable();
listQueryAdapter.Fill(listTable);

ddtype.DataSource = listTable;

Is your goal...

1. To count all the instances of "Bob Jones" in both tables (for example)
2. To count all the instances of "Bob Jones" in Results in one row and all the instances of "Bob Jones" in Archive_Results in a separate row?

Assuming it's #1 you'd want something like...

SELECT name, COUNT(*) FROM
(SELECT name FROM Results UNION ALL SELECT name FROM Archive_Results)
GROUP BY name
ORDER BY name

This is an old question but you can also use express-validator package to check request params

express-validator version 4 (latest):

validator = require('express-validator/check');

app.get('/show/:id', [

    validator.param('id').isMongoId().trim()

], function(req, res) {

    // validation result
    var errors = validator.validationResult(req);

    // check if there are errors
    if ( !errors.isEmpty() ) {
        return res.send('404');
    }

    // else 
    model.findById(req.params.id, function(err, doc) { 
        return res.send(doc);
    });

});

express-validator version 3:

var expressValidator = require('express-validator');
app.use(expressValidator(middlewareOptions));

app.get('/show/:id', function(req, res, next) {

    req.checkParams('id').isMongoId();

    // validation result
    req.getValidationResult().then(function(result) {

        // check if there are errors
        if ( !result.isEmpty() ) {
            return res.send('404');
        }

        // else
        model.findById(req.params.id, function(err, doc) {
            return res.send(doc);
        });

    });

});

The async way of life:

#! /usr/bin/node

const fs = require('fs');

function readall (stream)
{
  return new Promise ((resolve, reject) => {
    const chunks = [];
    stream.on ('error', (error) => reject (error));
    stream.on ('data',  (chunk) => chunk && chunks.push (chunk));
    stream.on ('end',   ()      => resolve (Buffer.concat (chunks)));
  });
}

function readfile (filename)
{
  return readall (fs.createReadStream (filename));
}

(async () => {
  let content = await readfile ('/etc/ssh/moduli').catch ((e) => {})
  if (content)
    console.log ("size:", content.length,
                 "head:", content.slice (0, 46).toString ());
})();

Here's a simple little function that will rbind two datasets together after auto-detecting what columns are missing from each and adding them with all NAs.

For whatever reason this returns MUCH faster on larger datasets than using the merge function.

fastmerge <- function(d1, d2) {
  d1.names <- names(d1)
  d2.names <- names(d2)

  # columns in d1 but not in d2
  d2.add <- setdiff(d1.names, d2.names)

  # columns in d2 but not in d1
  d1.add <- setdiff(d2.names, d1.names)

  # add blank columns to d2
  if(length(d2.add) > 0) {
    for(i in 1:length(d2.add)) {
      d2[d2.add[i]] <- NA
    }
  }

  # add blank columns to d1
  if(length(d1.add) > 0) {
    for(i in 1:length(d1.add)) {
      d1[d1.add[i]] <- NA
    }
  }

  return(rbind(d1, d2))
}

Try the following

double hours = (b-a).TotalHours;

If you just want the hour difference excluding the difference in days you can use the following

int hours = (b-a).Hours;

The difference between these two properties is mainly seen when the time difference is more than 1 day. The Hours property will only report the actual hour difference between the two dates. So if two dates differed by 100 years but occurred at the same time in the day, hours would return 0. But TotalHours will return the difference between in the total amount of hours that occurred between the two dates (876,000 hours in this case).

The other difference is that TotalHours will return fractional hours. This may or may not be what you want. If not, Math.Round can adjust it to your liking.

Yes there is a way to do it.

First declare a class.

//anyfile.ts
export class Custom
{
  name: string, 
  empoloyeeID: number
}

Then in your component import the class

import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
 name: string;
 empoloyeeID : number;
 empList: Array<Custom> = [];
 constructor() {

 }

 ngOnInit() {
 }
 onEmpCreate(){
   //console.log(this.name,this.empoloyeeID);
   let customObj = new Custom();
   customObj.name = "something";
   customObj.employeeId = 12; 
   this.empList.push(customObj);
   this.name ="";
   this.empoloyeeID = 0; 
 }
}

Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html

Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2

The method I prefer assigns an array of data to the combobox. Click on the body of your userform and change the "Click" event to "Initialize". Now the combobox will fill upon the initializing of the userform. I hope this helps.

Sub UserForm_Initialize()
  ComboBox1.List = Array("1001", "1002", "1003", "1004", "1005", "1006", "1007", "1008", "1009", "1010")
End Sub

There is a solution to this if you really need a static access to the current context. In Startup.Configure(….)

app.Use(async (httpContext, next) =>
{
    CallContext.LogicalSetData("CurrentContextKey", httpContext);
    try
    {
        await next();
    }
    finally
    {
        CallContext.FreeNamedDataSlot("CurrentContextKey");
    }
});

And when you need it you can get it with :

HttpContext context = CallContext.LogicalGetData("CurrentContextKey") as HttpContext;

I hope that helps. Keep in mind this workaround is when you don’t have a choice. The best practice is to use de dependency injection.

One could use Where-Object

if ((Get-Service | Where-Object {$_.Name -eq $serviceName}).length -eq 1) { "Service Exists" }

I've tied together a couple of the great examples above (thank you as always to Mr. Skeet and Mr. Karlsen) to include a couple of different Observables and utilized an interface to keep track of them in the Observer and allowed the Observer to to "observe" any number of Observables via an internal list:

namespace ObservablePattern
{
    using System;
    using System.Collections.Generic;

    internal static class Program
    {
        private static void Main()
        {
            var observable = new Observable();
            var anotherObservable = new AnotherObservable();

            using (IObserver observer = new Observer(observable))
            {
                observable.DoSomething();
                observer.Add(anotherObservable);
                anotherObservable.DoSomething();
            }

            Console.ReadLine();
        }
    }

    internal interface IObservable
    {
        event EventHandler SomethingHappened;
    }

    internal sealed class Observable : IObservable
    {
        public event EventHandler SomethingHappened;

        public void DoSomething()
        {
            var handler = this.SomethingHappened;

            Console.WriteLine("About to do something.");
            if (handler != null)
            {
                handler(this, EventArgs.Empty);
            }
        }
    }

    internal sealed class AnotherObservable : IObservable
    {
        public event EventHandler SomethingHappened;

        public void DoSomething()
        {
            var handler = this.SomethingHappened;

            Console.WriteLine("About to do something different.");
            if (handler != null)
            {
                handler(this, EventArgs.Empty);
            }
        }
    }

    internal interface IObserver : IDisposable
    {
        void Add(IObservable observable);

        void Remove(IObservable observable);
    }

    internal sealed class Observer : IObserver
    {
        private readonly Lazy<IList<IObservable>> observables =
            new Lazy<IList<IObservable>>(() => new List<IObservable>());

        public Observer()
        {
        }

        public Observer(IObservable observable) : this()
        {
            this.Add(observable);
        }

        public void Add(IObservable observable)
        {
            if (observable == null)
            {
                return;
            }

            lock (this.observables)
            {
                this.observables.Value.Add(observable);
                observable.SomethingHappened += HandleEvent;
            }
        }

        public void Remove(IObservable observable)
        {
            if (observable == null)
            {
                return;
            }

            lock (this.observables)
            {
                observable.SomethingHappened -= HandleEvent;
                this.observables.Value.Remove(observable);
            }
        }

        public void Dispose()
        {
            for (var i = this.observables.Value.Count - 1; i >= 0; i--)
            {
                this.Remove(this.observables.Value[i]);
            }
        }

        private static void HandleEvent(object sender, EventArgs args)
        {
            Console.WriteLine("Something happened to " + sender);
        }
    }
}

RFC 2616 (Hypertext Transfer Protocol — HTTP/1.1) states there is no limit to the length of a query string (section 3.2.1). RFC 3986 (Uniform Resource Identifier — URI) also states there is no limit, but indicates the hostname is limited to 255 characters because of DNS limitations (section 2.3.3).

While the specifications do not specify any maximum length, practical limits are imposed by web browser and server software. Based on research which is unfortunately no longer available on its original site (it leads to a shady seeming loan site) but which can still be found at Internet Archive Of Boutell.com:

• Microsoft Internet Explorer (Browser)
  Microsoft states that the maximum length of a URL in Internet Explorer is 2,083 characters, with no more than 2,048 characters in the path portion of the URL. Attempts to use URLs longer than this produced a clear error message in Internet Explorer.

• Microsoft Edge (Browser)
  The limit appears to be around 81578 characters. See URL Length limitation of Microsoft Edge

• Chrome
  It stops displaying the URL after 64k characters, but can serve more than 100k characters. No further testing was done beyond that.

• Firefox (Browser)
  After 65,536 characters, the location bar no longer displays the URL in Windows Firefox 1.5.x. However, longer URLs will work. No further testing was done after 100,000 characters.

• Safari (Browser)
  At least 80,000 characters will work. Testing was not tried beyond that.

• Opera (Browser)
  At least 190,000 characters will work. Stopped testing after 190,000 characters. Opera 9 for Windows continued to display a fully editable, copyable and pasteable URL in the location bar even at 190,000 characters.

• Apache (Server)
  Early attempts to measure the maximum URL length in web browsers bumped into a server URL length limit of approximately 4,000 characters, after which Apache produces a "413 Entity Too Large" error. The current up to date Apache build found in Red Hat Enterprise Linux 4 was used. The official Apache documentation only mentions an 8,192-byte limit on an individual field in a request.

• Microsoft Internet Information Server (Server)
  The default limit is 16,384 characters (yes, Microsoft's web server accepts longer URLs than Microsoft's web browser). This is configurable.

• Perl HTTP::Daemon (Server)
  Up to 8,000 bytes will work. Those constructing web application servers with Perl's HTTP::Daemon module will encounter a 16,384 byte limit on the combined size of all HTTP request headers. This does not include POST-method form data, file uploads, etc., but it does include the URL. In practice this resulted in a 413 error when a URL was significantly longer than 8,000 characters. This limitation can be easily removed. Look for all occurrences of 16x1024 in Daemon.pm and replace them with a larger value. Of course, this does increase your exposure to denial of service attacks.

Using DatabaseUtils.queryNumEntries():

public long getProfilesCount() {
    SQLiteDatabase db = this.getReadableDatabase();
    long count = DatabaseUtils.queryNumEntries(db, TABLE_NAME);
    db.close();
    return count;
}

or (more inefficiently)

public int getProfilesCount() {
    String countQuery = "SELECT  * FROM " + TABLE_NAME;
    SQLiteDatabase db = this.getReadableDatabase();
    Cursor cursor = db.rawQuery(countQuery, null);
    int count = cursor.getCount();
    cursor.close();
    return count;
}

In Activity:

int profile_counts = db.getProfilesCount();
    db.close();

If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900

If your date is text and you need to convert it then DATEVALUE will do this:

A composer dump-autoload should fix it.

The issue with the null connection is related to the findBT() function. you must change the device name from "MattsBlueTooth" to your device name as well as confirm the UUID for your service/device. Use something like BLEScanner app to confrim both on Android.

Escape the backslash character.

foo.split('\\')

Essentially, PHPStorm = WebStorm + PHP, SQL and more.

BUT (and this is a very important "but") because it is capable of parsing so much more, it quite often fails to parse Node.js dependencies, as they (probably) conflict with some other syntax it is capable of parsing.

The most notable example of that would be Mongoose model definition, where WebStorm easily recognizes mongoose.model method, whereas PHPStorm marks it as unresolved as soon as you connect Node.js plugin.

Surprisingly, it manages to resolve the method if you turn the plugin off, but leave the core modules connected, but then it cannot be used for debugging. And this happens to quite a few methods out there.

All this goes for PHPStorm 8.0.1, maybe in later releases this annoying bug would be fixed.

When dealing with null, = does not match the null values. You can use IS NULL or IS NOT NULL

UPDATE `smartmeter_usage`.`users_reporting` 
SET panel_id = 3 WHERE panel_id IS NULL

LIMIT can be used with UPDATE but with the row count only

This is just an example how to use it in a unit test that I hacked to debug this issue. The key ingredients are

• mapper.registerModule(new JavaTimeModule());
• maven dependency of <artifactId>jackson-datatype-jsr310</artifactId>

Some interesting excerpts from the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.
...
When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of /etc/bash.bashrc and ~/.bashrc.

So have a look at /etc/profile or /etc/bash.bashrc, these files are the right places for global settings. Put something like this in them to set up an environement variable:

export MY_VAR=xxx

If you don't want your code to depend on other packages, you can always just write these functions:

perm = function(n, x) {
  factorial(n) / factorial(n-x)
}

comb = function(n, x) {
  factorial(n) / factorial(n-x) / factorial(x)
}

SQLite supports replacing a row if it already exists:

INSERT OR REPLACE INTO [...blah...]

You can shorten this to

REPLACE INTO [...blah...]

This shortcut was added to be compatible with the MySQL REPLACE INTO expression.

In Vue2 be aware that you can access this.$refs.uniqueName only after mounting the component.

You should change the generated HTML to not use inline javascript, and use addEventListener instead.

If you can not in any way change the HTML, you could get the onclick attributes, the functions and arguments used, and "convert" it to unobtrusive javascript instead by removing the onclick handlers, and using event listeners.

We'd start by getting the values from the attributes

$('button').each(function(i, el) {_x000D_
    var funcs = [];_x000D_
_x000D_
 $(el).attr('onclick').split(';').map(function(item) {_x000D_
     var fn     = item.split('(').shift(),_x000D_
         params = item.match(/\(([^)]+)\)/), _x000D_
            args;_x000D_
            _x000D_
        if (params && params.length) {_x000D_
         args = params[1].split(',');_x000D_
            if (args && args.length) {_x000D_
                args = args.map(function(par) {_x000D_
              return par.trim().replace(/('")/g,"");_x000D_

        funcs.push([fn, args||[]]);_x000D_
    });_x000D_
  _x000D_
    $(el).data('args', funcs); // store in jQuery's $.data_x000D_
  _x000D_
    console.log( $(el).data('args') );_x000D_

<button onclick="doSomething('param')" id="id_button1">action1</button>_x000D_
<button onclick="doAnotherSomething('param1', 'param2')" id="id_button1">action2</button>._x000D_
<button onclick="doDifferentThing()" id="id_button3">action3</button>

That gives us an array of all and any global methods called by the onclick attribute, and the arguments passed, so we can replicate it.

Then we'd just remove all the inline javascript handlers

$('button').removeAttr('onclick')

and attach our own handlers

$('button').on('click', function() {...}

Inside those handlers we'd get the stored original function calls and their arguments, and call them.
As we know any function called by inline javascript are global, we can call them with window[functionName].apply(this-value, argumentsArray), so

$('button').on('click', function() {
    var element = this;
    $.each(($(this).data('args') || []), function(_,fn) {
        if (fn[0] in window) window[fn[0]].apply(element, fn[1]);
    });
});

And inside that click handler we can add anything we want before or after the original functions are called.

$('button').each(function(i, el) {_x000D_
    var funcs = [];_x000D_
_x000D_
 $(el).attr('onclick').split(';').map(function(item) {_x000D_

Use size_t :

for (size_t i=0; i < polygon.size(); i++)

Quoting Wikipedia:

The stdlib.h and stddef.h header files define a datatype called size_t which is used to represent the size of an object. Library functions that take sizes expect them to be of type size_t, and the sizeof operator evaluates to size_t.

The actual type of size_t is platform-dependent; a common mistake is to assume size_t is the same as unsigned int, which can lead to programming errors, particularly as 64-bit architectures become more prevalent.

parseInt() should do the trick

var number = "25";
var sum = parseInt(number, 10) + 10;
var pin = number + 10;

Gives you

sum == 35
pin == "2510"

http://www.w3schools.com/jsref/jsref_parseint.asp

Note: The 10 in parseInt(number, 10) specifies decimal (base-10). Without this some browsers may not interpret the string correctly. See MDN: parseInt.

If you have only one char and not a string, you can use:

'\n'.charCodeAt();

omitting the 0...

It used to be significantly slower than 'n'.charCodeAt(0), but I've tested it now and I do not see any difference anymore (executed 10 billions times with and without the 0). Tested for performance only in Chrome and Firefox.

Git is Version Control System, created for software development, so from the whole set of modes and permissions it stores only executable bit (for ordinary files) and symlink bit. If you want to store full permissions, you need third party tool, like git-cache-meta (mentioned by VonC), or Metastore (used by etckeeper). Or you can use IsiSetup, which IIRC uses git as backend.

See Interfaces, frontends, and tools page on Git Wiki.

This is a 3 years old question but I had the same problem today. I looked your edited solution but I think that it can sacrifice the performance because it has to make a double request. So if anyone needs another solution that doesn't imply to call the service twice then this is the way I did it:

<form id="export-csv-form" method="POST" action="/the/path/to/file">
    <input type="hidden" name="anyValueToPassTheServer" value="">
</form>

This form is just used to call the service and avoid to use a window.location(). After that you just simply have to make a form submit from jquery in order to call the service and get the file. It's pretty simple but this way you can make a download using a POST. I now that this could be easier if the service you're calling is a GET, but that's not my case.

A dummy answer :-

I think explanation is given in above answer, so i am just gonna tell you where to use STRONG and where to use WEAK :

Use of Weak :- 1. Delegates 2. Outlets 3. Subviews 4. Controls, etc.

Use of Strong :- Remaining everywhere which is not included in WEAK.

Accessing indexes & Performance Benchmarking of approaches

The fastest way to access indexes of list within loop in Python 3.7 is to use the enumerate method for small, medium and huge lists.

Please see different approaches which can be used to iterate over list and access index value and their performance metrics (which I suppose would be useful for you) in code samples below:

# Using range
def range_loop(iterable):
    for i in range(len(iterable)):
        1 + iterable[i]

# Using enumerate
def enumerate_loop(iterable):
    for i, val in enumerate(iterable):
        1 + val

# Manual indexing
def manual_indexing_loop(iterable):
    index = 0
    for item in iterable:
        1 + item
        index += 1

See performance metrics for each method below:

from timeit import timeit

def measure(l, number=10000):
    print("Measure speed for list with %d items" % len(l))
    print("range: ", timeit(lambda :range_loop(l), number=number))
    print("enumerate: ", timeit(lambda :enumerate_loop(l), number=number))
    print("manual_indexing: ", timeit(lambda :manual_indexing_loop(l), number=number))

# Measure speed for list with 1000 items
measure(range(1000))
# range:  1.161622366
# enumerate:  0.5661940879999996
# manual_indexing:  0.610455682

# Measure speed for list with 100000 items
measure(range(10000))
# range:  11.794482958
# enumerate:  6.197628574000001
# manual_indexing:  6.935181098000001

# Measure speed for list with 10000000 items
measure(range(10000000), number=100)
# range:  121.416859069
# enumerate:  62.718909123
# manual_indexing:  69.59575057400002

As the result, using enumerate method is the fastest method for iteration when the index needed.

Adding some useful links below:

• What is the difference between range and xrange functions in Python 2.X?

• What is faster for loop using enumerate or for loop using xrange in Python?

• range(len(list)) or enumerate(list)?

Can I just ask about the long term need for this facility - is it for debuging purposes?

If so, then you may want to consider using a proper debugger, such as the one found in Visual Studio, as this allows you to step through the procedure in a more controlled way, and avoids having to constantly add/remove PRINT statement from the procedure.

Just my opinion, but I prefer the debugger approach - for code and databases.

I realize this is years late, but I thought I could expand on Conor's answer and add a little bit more to the discussion.

Can someone give me a step by step description of how cookie based authentication works? I've never done anything involving either authentication or cookies. What does the browser need to do? What does the server need to do? In what order? How do we keep things secure?

Step 1: Client > Signing up

Before anything else, the user has to sign up. The client posts a HTTP request to the server containing his/her username and password.

Step 2: Server > Handling sign up

The server receives this request and hashes the password before storing the username and password in your database. This way, if someone gains access to your database they won't see your users' actual passwords.

Step 3: Client > User login

Now your user logs in. He/she provides their username/password and again, this is posted as a HTTP request to the server.

Step 4: Server > Validating login

The server looks up the username in the database, hashes the supplied login password, and compares it to the previously hashed password in the database. If it doesn't check out, we may deny them access by sending a 401 status code and ending the request.

Step 5: Server > Generating access token

If everything checks out, we're going to create an access token, which uniquely identifies the user's session. Still in the server, we do two things with the access token:

1. Store it in the database associated with that user
2. Attach it to a response cookie to be returned to the client. Be sure to set an expiration date/time to limit the user's session

Henceforth, the cookies will be attached to every request (and response) made between the client and server.

Step 6: Client > Making page requests

Back on the client side, we are now logged in. Every time the client makes a request for a page that requires authorization (i.e. they need to be logged in), the server obtains the access token from the cookie and checks it against the one in the database associated with that user. If it checks out, access is granted.

This should get you started. Be sure to clear the cookies upon logout!

I solved it in two steps. To rename folder using mv command you need rights to do so, if you don't have right you can follow these steps. Suppose you want to rename casesensitive to Casesensitive.

Step 1: Rename the folder (casesensitive) to something else from explorer. eg Rename casesensitive to folder1 commit this change.

Step 2: Rename this newly named folder(folder1) to the expected case sensitive name (Casesensitive ) eg. Rename folder1 to Casesensitive. Commit this change.

Get a random number. Is it stored in the array already? If not, store it. If so, then go get another random number and repeat.

Following worked for me:

1. Uninstall the previously installed ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’.
2. Install 64-bit versions of ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’. https://littletalk.wordpress.com/2013/09/23/install-and-configure-the-office-365-powershell-cmdlets/

If you get the following error In order to install Windows Azure Active Directory Module for Windows PowerShell, you must have Microsoft Online Services Sign-In Assistant version 7.0 or greater installed on this computer, then install the Microsoft Online Services Sign-In Assistant for IT Professionals BETA: http://www.microsoft.com/en-us/download/details.aspx?id=39267

3. Copy the folders called MSOnline and MSOnline Extended from the source

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\

to the folder

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\

https://stackoverflow.com/a/16018733/5810078.

(But I have actually copied all the possible files from

C:\Windows\System32\WindowsPowerShell\v1.0\

to

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\

(For copying you need to alter the security permissions of that folder))

for example I faced this in express node.js when trying to create route for paths not starting with /internal

app.get(`\/(?!internal).*`, (req, res)=>{

and after long trying it just worked when passing it as a RegExp Object using new RegExp()

app.get(new RegExp("\/(?!internal).*"), (req, res)=>{

this may help if you are getting this common issue in routing

Something like this may be:

String str = "abcdefghijklmnopqrtuvwxyz";
if (str.length() > 8)
    str = str.substring(0, 8) + "...";

If you're using the Spring Security framework, you can use:

import org.springframework.security.crypto.codec.Hex

final String testString = "Test String";
final byte[] byteArray = testString.getBytes();
System.out.println(Hex.encode(byteArray));

For very simple Linux support if you like TextMate, try just gedit loaded with the right plugins. Easy to set up and really customizable, I use it for just about everything. There's also a lot of talk about emacs plugins if you're already using that normally.

Here is the simple ListView with different images. First of all you have to copy the different kinds of images and paste it to the res/drawable-hdpi in your project. Images should be (.png)file format. then copy this code.

In main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:orientation="vertical" >

  <TextView
      android:id="@+id/textview"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content" />

 <ListView
     android:id="@+id/listview"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content" />

create listview_layout.xml and paste this code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

   <ImageView
      android:id="@+id/flag"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:contentDescription="@string/hello"
      android:paddingTop="10dp"
      android:paddingRight="10dp"
      android:paddingBottom="10dp" />

   <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical" >

     <TextView
        android:id="@+id/txt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="15dp"
        android:text="TextView1" />

    <TextView
        android:id="@+id/cur"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="10dp"

Why not use reduce so that we can take colspan into account? :)

function getColumns(table) {
    var cellsArray = [];
    var cells = table.rows[0].cells;

    // Cast the cells to an array
    // (there are *cooler* ways of doing this, but this is the fastest by far)
    // Taken from https://stackoverflow.com/a/15144269/6424295
    for(var i=-1, l=cells.length; ++i!==l; cellsArray[i]=cells[i]);

    return cellsArray.reduce(
        (cols, cell) =>
            // Check if the cell is visible and add it / ignore it
            (cell.offsetParent !== null) ? cols += cell.colSpan : cols,
        0
    );
}

The answer of Flip is computationally more consistent than the Muis one.

Using double number format, you could see the roundoff problem in the Muis approach:

When you divide and subtract, a roundoff appears in the previous stored value, changing it.

However, the Flip approach preserves the stored value and reduces the number of divisions, hence, reducing the roundoff, and minimizing the error propagated to the stored value. Adding only will bring up roundoffs if there is something to add (when N is big, there is nothing to add)

Those changes are remarkable when you make a mean of big values tend their mean to zero.

I show you the results using a spreadsheet program:

Firstly, the results obtained:

The A and B columns are the n and X_n values, respectively.

The C column is the Flip approach, and the D one is the Muis approach, the result stored in the mean. The E column corresponds with the medium value used in the computation.

A graph showing the mean of even values is the next one:

As you can see, there is big differences between both approachs.

The selected answer authored by Anurag is only partially correct. Due to some internals of jQuery's event handling, the proposed bindFirst function will not work if you have a mix of handlers with and without filters (ie: $(document).on("click", handler) vs $(document).on("click", "button", handler)).

The issue is that jQuery will place (and expect) that the first elements in the handler array will be these filtered handlers, so placing our event without a filter at the beginning breaks this logic and things start to fall apart. The updated bindFirst function should be as follows:

$.fn.bindFirst = function (name, fn) {
    // bind as you normally would
    // don't want to miss out on any jQuery magic
    this.on(name, fn);

    // Thanks to a comment by @Martin, adding support for
    // namespaced events too.
    this.each(function () {
        var handlers = $._data(this, 'events')[name.split('.')[0]];
        // take out the handler we just inserted from the end
        var handler = handlers.pop();
        // get the index of the first handler without a selector
        var firstNonDelegate = handlers.first(function(h) { return !h.selector; });
        var index = firstNonDelegate ? handlers.indexOf(firstNonDelegate)
                                     : handlers.length; // Either all handlers are selectors or we have no handlers
        // move it at the beginning
        handlers.splice(index, 0, handler);
    });
};

this error basically comes when you use the object before using it.

Assuming that this is about OAuth 2.0 since it is about JWTs and refresh tokens...:

1. just like an access token, in principle a refresh token can be anything including all of the options you describe; a JWT could be used when the Authorization Server wants to be stateless or wants to enforce some sort of "proof-of-possession" semantics on to the client presenting it; note that a refresh token differs from an access token in that it is not presented to a Resource Server but only to the Authorization Server that issued it in the first place, so the self-contained validation optimization for JWTs-as-access-tokens does not hold for refresh tokens

2. that depends on the security/access of the database; if the database can be accessed by other parties/servers/applications/users, then yes (but your mileage may vary with where and how you store the encryption key...)

3. an Authorization Server may issue both access tokens and refresh tokens at the same time, depending on the grant that is used by the client to obtain them; the spec contains the details and options on each of the standardized grants

The question itself has already been addressed above. Just adding part of the default values.

As per http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionX.html

The default value of Xmx will depend on platform and amount of memory available in the system.
