In SpringBoot 2.1, I found another solution. Extend standard factory class method getTomcatWebServer. And then return it as a bean from anywhere.

public class CustomTomcatServletWebServerFactory extends TomcatServletWebServerFactory {

    @Override
    protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
        System.setProperty("catalina.useNaming", "true");
        tomcat.enableNaming();
        return new TomcatWebServer(tomcat, getPort() >= 0);
    }
}

@Component
public class TomcatConfiguration {
    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new CustomTomcatServletWebServerFactory();

        return factory;
    }

Loading resources from context.xml doesn't work though. Will try to find out.

There is similar issue. I added listener as given here

https://stackoverflow.com/questions/3145936/spring-security-j-spring-security-logout-problem

It worked for me adding below lines to web.xml. Posting it very late, should help someone looking for answer.

<listener>
    <listener-class> org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
</listener>

In my case the problem was an external running exe file - namely:

WUDFCompanionHost.exe

under the name of

"Windows Driver Foundation - User-mode Driver Companion Framework Host Process".

Process, which has taken a steady 10% of the CPU. Killing it helped directly and withing a second the page has loaded.

In my case, I was defining a bean and autowiring it in the constructor of the same class file.

@SpringBootApplication
public class MyApplication {
    private MyBean myBean;

    public MyApplication(MyBean myBean) {
        this.myBean = myBean;
    }

    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

My solution was to move the bean definition to another class file.

@Configuration
public CustomConfig {
    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

Documentation: C.2.3.1 <jee:jndi-lookup/> (simple)

Example:

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/MyDataSource"/>

You just need to find out what JNDI name your appserver has bound the datasource to. This is entirely server-specific, consult the docs on your server to find out how.

Remember to declare the jee namespace at the top of your beans file, as described in C.2.3 The jee schema.

There is also a property resourceRef of JndiObjectFactoryBean that is, when set to true, used to automatically prepend the string java:comp/env/ if it is not already present.

<bean id="someId" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="jdbc/loc"/>
  <property name="resourceRef" value="true"/>
</bean>

I tried the code provided above, but it gave an error 9 for me. I made this code, and it worked fine for my purposes. I hope others find it useful as well.

Function mergeArrays(ByRef arr1() As Variant, arr2() As Variant) As Variant

    Dim returnThis() As Variant
    Dim len1 As Integer, len2 As Integer, lenRe As Integer, counter As Integer
    len1 = UBound(arr1)
    len2 = UBound(arr2)
    lenRe = len1 + len2
    ReDim returnThis(1 To lenRe)
    counter = 1

    Do While counter <= len1 'get first array in returnThis
        returnThis(counter) = arr1(counter)
        counter = counter + 1
    Loop
    Do While counter <= lenRe 'get the second array in returnThis
        returnThis(counter) = arr2(counter - len1)
        counter = counter + 1
    Loop

mergeArrays = returnThis
End Function

----Ctrl + c then choose Y from the Y/N option provided.

Just do this way:-

$('ul li').on('click', function(e) {
    alert($(this).index()); 
});

OR

$('ul li').click(function() {
    alert($(this).index());
});

See, here you can get only date by passing a format string. You can get a different date format as per your requirement as given below for current date:

DateTime.Now.ToString("M/d/yyyy");

Result : "9/1/2016"

DateTime.Now.ToString("M-d-yyyy");

Result : "9-1-2016"

DateTime.Now.ToString("yyyy-MM-dd");

Result : "2016-09-01"

DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss");

Result : "2016-09-01 09:20:10"

For more details take a look at MSDN reference for Custom Date and Time Format Strings

Here is a simple example of encrypting strings in C# using AES CBC mode with random IV and HMAC and password-derived keys, to show the basic moving parts:

private byte[] EncryptBytes(byte[] key, byte[] plaintext)
{
    using (var cipher = new RijndaelManaged { Key = key })
    {
        using (var encryptor = cipher.CreateEncryptor())
        {
            var ciphertext = encryptor.TransformFinalBlock(plaintext, 0, plaintext.Length);

            // IV is prepended to ciphertext
            return cipher.IV.Concat(ciphertext).ToArray();
        }
    }
}

private byte[] DecryptBytes(byte[] key, byte[] packed)
{
    using (var cipher = new RijndaelManaged { Key = key })
    {
        int ivSize = cipher.BlockSize / 8;

        cipher.IV = packed.Take(ivSize).ToArray();

        using (var encryptor = cipher.CreateDecryptor())
        {
            return encryptor.TransformFinalBlock(packed, ivSize, packed.Length - ivSize);
        }
    }
}

private byte[] AddMac(byte[] key, byte[] data)
{
    using (var hmac = new HMACSHA256(key))
    {
        var macBytes = hmac.ComputeHash(data);

        // HMAC is appended to data
        return data.Concat(macBytes).ToArray();
    }
}

private bool BadMac(byte[] found, byte[] computed)
{
    int mismatch = 0;

    // Aim for consistent timing regardless of inputs
    for (int i = 0; i < found.Length; i++)
    {
        mismatch += found[i] == computed[i] ? 0 : 1;
    }

    return mismatch != 0;
}

private byte[] RemoveMac(byte[] key, byte[] data)
{
    using (var hmac = new HMACSHA256(key))
    {
        int macSize = hmac.HashSize / 8;

        var packed = data.Take(data.Length - macSize).ToArray();

        var foundMac = data.Skip(packed.Length).ToArray();

        var computedMac = hmac.ComputeHash(packed);

        if (this.BadMac(foundMac, computedMac))
        {
            throw new Exception("Bad MAC");
        }

        return packed;
    }            
}

private List<byte[]> DeriveTwoKeys(string password)
{
    var salt = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 };

    var kdf = new Rfc2898DeriveBytes(password, salt, 10000);

    var bytes = kdf.GetBytes(32); // Two keys 128 bits each

    return new List<byte[]> { bytes.Take(16).ToArray(), bytes.Skip(16).ToArray() };
}

public byte[] EncryptString(string password, String message)
{
    var keys = this.DeriveTwoKeys(password);

    var plaintext = Encoding.UTF8.GetBytes(message);

    var packed = this.EncryptBytes(keys[0], plaintext);

    return this.AddMac(keys[1], packed);
}

public String DecryptString(string password, byte[] secret)
{
    var keys = this.DeriveTwoKeys(password);

    var packed = this.RemoveMac(keys[1], secret);

    var plaintext = this.DecryptBytes(keys[0], packed);

    var password = "correcthorsebatterystaple";

    var secret = this.EncryptString(password, "Hello World");

Getting the total number of results and paginating are two different operations. For the sake of this example, let's assume that the query you're dealing with is

SELECT * FROM Orders WHERE OrderDate >= '1980-01-01' ORDER BY OrderDate

In this case, you would determine the total number of results using:

SELECT COUNT(*) FROM Orders WHERE OrderDate >= '1980-01-01'

...which may seem inefficient, but is actually pretty performant, assuming all indexes etc. are properly set up.

Next, to get actual results back in a paged fashion, the following query would be most efficient:

SELECT  *
FROM    ( SELECT    ROW_NUMBER() OVER ( ORDER BY OrderDate ) AS RowNum, *
          FROM      Orders
          WHERE     OrderDate >= '1980-01-01'
        ) AS RowConstrainedResult
WHERE   RowNum >= 1
    AND RowNum < 20
ORDER BY RowNum

This will return rows 1-19 of the original query. The cool thing here, especially for web apps, is that you don't have to keep any state, except the row numbers to be returned.

By using System.exit(0); you would close the entire process. Is that what you wanted or did you intend to close only the GUI window and allow the process to continue running?

The quickest, easiest and most robust way to simply close a JFrame or JPanel with the click of a JButton is to add an actionListener to the JButton which will execute the line of code below when the JButton is clicked:

this.dispose();

If you are using the NetBeans GUI designer, the easiest way to add this actionListener is to enter the GUI editor window and double click the JButton component. Doing this will automatically create an actionListener and actionEvent, which can be modified manually by you.

You also want to say, that strings in your code are utf-8. See Why does modern Perl avoid UTF-8 by default?. So set not only PERL_UNICODE=SDAL but also PERL5OPT=-Mutf8.

(disclaimer - I work for Atalasoft)

If you present your PDF documents with the Atalasoft web image viewer, you can prevent the PDF from being downloaded. You could also control printing from javascript on the client side.

There are two possibilities.

1. You forgot to put the %id% in the jstack call.

   jstack %id% > jstack.txt
   

So the whole correct batch file should be:

@echo off
set /p id=Enter ID: 
echo %id%
jstack %id% > jstack.txt

And/Or 2. You did put it in the code (and forgot to tell us in the question) but when you ran the batch file you hit the Enter key instead of typing an ID (say 1234).

What's happening is the result of these two mistakes: jstack is supposed to be called with the id that you supply it.

But in your case (according to the code you supplied in the question) you called it without any variable. You wrote:

jstack > jstack.txt

So when you run jstack with no variable it outputs the following:

Terminate batch file Y/N? 

Your second mistake is that you pressed Enter instead of giving a value when the program asked you: Enter ID:. If you would have put in an ID at this point, say 1234, the %id% variable would become that value, in our case 1234. But you did NOT supply a value and instead pressed Enter. When you don't give the variable any value, and if that variable was not set to anything else before, then the variable %id% is set to the prompt of the set command!! So now %id% is set to Enter ID: which was echoed on your screen as requested in the batch file BEFORE you called the jstack.

But I suspect you DID have the jstack %id% > jstack.txt in your batch file code with the %id (and omitted it by mistake from the question), and that you hit enter without typing in an id. The batch program then echoed the id, which is now "Enter ID:", and then ran jstack Enter ID: > jstack.txt

Jstack itself echoed the input, encountered a mistake and asked to terminate.
And all this was written into the jstack.txt file.

we can use Outputstream to output our Object to internal memory. And convert to string then save in preference. For example:

    mPrefs = getPreferences(MODE_PRIVATE);
    SharedPreferences.Editor ed = mPrefs.edit();
    ByteArrayOutputStream arrayOutputStream = new ByteArrayOutputStream();

    ObjectOutputStream objectOutput;
    try {
        objectOutput = new ObjectOutputStream(arrayOutputStream);
        objectOutput.writeObject(object);
        byte[] data = arrayOutputStream.toByteArray();
        objectOutput.close();
        arrayOutputStream.close();

        ByteArrayOutputStream out = new ByteArrayOutputStream();
        Base64OutputStream b64 = new Base64OutputStream(out, Base64.DEFAULT);
        b64.write(data);
        b64.close();
        out.close();

        ed.putString(key, new String(out.toByteArray()));

        ed.commit();
    } catch (IOException e) {
        e.printStackTrace();
    }

when we need to extract Object from Preference. Use the code as below

    byte[] bytes = mPrefs.getString(indexName, "{}").getBytes();
    if (bytes.length == 0) {
        return null;
    }
    ByteArrayInputStream byteArray = new ByteArrayInputStream(bytes);
    Base64InputStream base64InputStream = new Base64InputStream(byteArray, Base64.DEFAULT);
    ObjectInputStream in;
    in = new ObjectInputStream(base64InputStream);
    MyObject myObject = (MyObject) in.readObject();

Because the dot is inside character class (square brackets []).

Take a look at http://www.regular-expressions.info/reference.html, it says (under char class section):

Any character except ^-]\ add that character to the possible matches for the character class.

@WebWanderer 's answer is very close to the DateDiff using SQL server, but inaccurate. That is because of the usage of age() function.

e.g. days between '2019-07-29' and '2020-06-25' should return 332, however, using the age() function it will returns 327. Because the age() returns '10 mons 27 days" and it treats each month as 30 days which is incorrect.

You shold use the timestamp to get the accurate result. e.g.

ceil((select extract(epoch from (current_date::timestamp - <your_date>::timestamp)) / 86400))

You can also use guava Table implementation for this.

Table represents a special map where two keys can be specified in combined fashion to refer to a single value. It is similar to creating a map of maps.

//create a table
  Table<String, String, String> employeeTable = HashBasedTable.create();

  //initialize the table with employee details
  employeeTable.put("IBM", "101","Mahesh");
  employeeTable.put("IBM", "102","Ramesh");
  employeeTable.put("IBM", "103","Suresh");

  employeeTable.put("Microsoft", "111","Sohan");
  employeeTable.put("Microsoft", "112","Mohan");
  employeeTable.put("Microsoft", "113","Rohan");

  employeeTable.put("TCS", "121","Ram");
  employeeTable.put("TCS", "122","Shyam");
  employeeTable.put("TCS", "123","Sunil");

  //get Map corresponding to IBM
  Map<String,String> ibmEmployees =  employeeTable.row("IBM");

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName);

WPF how to make textbox lose focus after hitting enter

Diff command in Unix is used to find the differences between files(all types). Since directory is also a type of file, the differences between two directories can easily be figure out by using diff commands. For more option use man diff on your unix box.

 -b              Ignores trailing blanks  (spaces  and  tabs)
                 and   treats  other  strings  of  blanks  as
                 equivalent.

 -i              Ignores the case of  letters.  For  example,
                 `A' will compare equal to `a'.
 -t              Expands <TAB> characters  in  output  lines.
                 Normal or -c output adds character(s) to the
                 front of each line that may adversely affect
                 the indentation of the original source lines
                 and  make  the  output  lines  difficult  to
                 interpret.  This  option  will  preserve the
                 original source's indentation.

 -w              Ignores all blanks (<SPACE> and <TAB>  char-
                 acters)  and  treats  all  other  strings of
                 blanks   as   equivalent.    For    example,
                 `if ( a == b )'   will   compare   equal  to
                 `if(a==b)'.

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

My solution (example with a random mp4 video file):

1. Set a file to device:

   adb push /home/myuser/myVideoFile.mp4 /storage/emulated/legacy/
   

2. Get a file from device:

   adb pull /storage/emulated/legacy/myVideoFile.mp4 
   

For retrieve the path in the code:

String myFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myVideoFile.mp4";

This is all. This solution doesn't give permission problems and it works fine.

Last point: I wanted to change the video metadata information. If you want to write into your device you should change the permission in the AndroidManifest.xml. Add this line:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

In modern browsers (IE8, Firefox, Chrome, Opera, Safari) you can use querySelector():

function test(el){
  el.querySelector("#child").style.display = "none";
}

For older browsers (<=IE7), you would have to use some sort of library, such as Sizzle or a framework, such as jQuery, to work with selectors.

As mentioned, IDs are supposed to be unique within a document, so it's easiest to just use document.getElementById("child").

I'd go with option 3, but have an abstract setMyInt method that subclasses are forced to implement. This way you won't have the problem of a derived class forgetting to set it in the constructor.

abstract class Base 
{
 protected int myInt;
 protected abstract void setMyInt();
}

class Derived : Base 
{
 override protected void setMyInt()
 {
   myInt = 3;
 }
}

By the way, with option one, if you don't specify set; in your abstract base class property, the derived class won't have to implement it.

abstract class Father
{
    abstract public int MyInt { get; }
}

class Son : Father
{
    public override int MyInt
    {
        get { return 1; }
    }
}

For those looking for a Swift version of @amro's answer:

    let userDefaults = NSUserDefaults.standardUserDefaults()

    if userDefaults.boolForKey("hasRunBefore") == false {

        // remove keychain items here


        // update the flag indicator
        userDefaults.setBool(true, forKey: "hasRunBefore")
        userDefaults.synchronize() // forces the app to update the NSUserDefaults

        return
    }

It appears this can be done. I'm unable to determine the version of GCC that it was added, but it was sometime before June 2010.

Here's an example:

#pragma GCC diagnostic error "-Wuninitialized"
    foo(a);         /* error is given for this one */
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wuninitialized"
    foo(b);         /* no diagnostic for this one */
#pragma GCC diagnostic pop
    foo(c);         /* error is given for this one */
#pragma GCC diagnostic pop
    foo(d);         /* depends on command line options */

This worked for me. If we want to just add an additional field in ModelSerializer, we can do it like below, and also the field can be assigned some val after some calculations of lookup. Or in some cases, if we want to send the parameters in API response.

In model.py

class Foo(models.Model):
    """Model Foo"""
    name = models.CharField(max_length=30, help_text="Customer Name")

In serializer.py

class FooSerializer(serializers.ModelSerializer):
    retrieved_time = serializers.SerializerMethodField()
    
    @classmethod
    def get_retrieved_time(self, object):
        """getter method to add field retrieved_time"""
        return None

  class Meta:
        model = Foo
        fields = ('id', 'name', 'retrieved_time ')

Hope this could help someone.

You can use -m -c -r to make migration, model and controller.

Why not to extend the existing comperator and overwrite super and nor the result. The implementation the Comperator Interface is not nessesery but it makes it more clear what happens.

In result you get a easy reusable Class File, testable unit step and clear javadoc.

public class NorCoperator extends ExistingComperator implements Comparator<MyClass> {
    @Override
    public int compare(MyClass a, MyClass b) throws Exception {
        return super.compare(a, b)*-1;
    }
}

I would suggest separating your code based on the functionality and purpose specific to each sheet or module. In this manner, you would only put code relative to a sheet's UI inside the sheet's module and only put code related to modules in respective modules. Also, use separate modules to encapsulate code that is shared or reused among several different sheets.

For example, let's say you multiple sheets that are responsible for displaying data from a database in a special way. What kinds of functionality do we have in this situation? We have functionality related to each specific sheet, tasks related to getting data from the database, and tasks related to populating a sheet with data. In this case, I might start with a module for the data access, a module for populating a sheet with data, and within each sheet I'd have code for accessing code in those modules.

It might be laid out like this.

Module: DataAccess:

Function GetData(strTableName As String, strCondition1 As String) As Recordset
    'Code Related to getting data from the database'
End Function

Module: PopulateSheet:

Sub PopulateASheet(wsSheet As Worksheet, rs As Recordset)
    'Code to populate a worksheet '
End Function

Sheet: Sheet1 Code:

Sub GetDataAndPopulate()
    'Sample Code'
     Dim rs As New Recordset
     Dim ws As Worksheet
     Dim strParam As String
     Set ws = ActiveSheet
     strParam = ws.Range("A1").Value

     Set rs = GetData("Orders",strParam)

     PopulateASheet ws, rs
End Sub

Sub Button1_Click()
    Call GetDataAndPopulate
End Sub

You'll want to use .indexOf() and .splice(). Something like:

tag_story.splice(tag_story.indexOf(90),1);

As per this gist, the solution is to create a ~/.bash_profile (in HOME directory) that contains:

export SHELLOPTS

The top answer is great.

I would just add, that it becomes easy to understand if you think about remotes as locations other than your computer that you may want to move your code to.

Some very good examples are:

• GitHub
• A server to host your app

So you can certainly have multiple remotes. A very common pattern is to use GitHub to store your code, and a server to host your application (if it's a web application). Then you would have 2 remotes (possibly more if you have other environments).

Try opening your git config by typing git config -e

Note: press escape, then :, then q then enter to quit out

Example

Here's what you might see in your git configs if you had 3 remotes. In this example, 1 remote (called 'origin') is GitHub, another remote (called 'staging') is a staging server, and the third (called 'heroku') is a production server.

        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
        ignorecase = true
        precomposeunicode = true
[remote "origin"]
        url = https://github.com/username/reponame.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
        remote = origin
        merge = refs/heads/master
[remote "heroku"]
        url = https://git.heroku.com/appname.git
        fetch = +refs/heads/*:refs/remotes/heroku/*
[remote "staging"]
        url = https://git.heroku.com/warm-bedlands-98000.git
        fetch = +refs/heads/*:refs/remotes/staging/*

The three lines starting with [remote ... show us the remotes we can push to.

Running git push origin will push to the url for '[remote "origin"]', i.e. to GitHub

But similarly, we could push to another remote, say, '[remote "staging"]', with git push staging, then it would push to https://git.heroku.com/warm-bedlands-98000.git.

In the example above, we can see the 3 remotes with git remote:

git remote   
heroku
origin
staging

Summary or origin

Remotes are simply places on the internet that you may have a reason to send your code to. GitHub is an obvious place, as are servers that host your app, and you may have other locations too. git push origin simply means it will push to 'origin', which is the name GitHub chooses to default to.

As for branchname

branchname is simply what you're pushing to the remote. According the git push help docs, the branchname argument is technically a refspec, which, for practical purposes, is the branch you want to push.

• Read more in the docs for git push by running: git push --help

NSString *stringWithoutAsterisk(NSString *string) {
    NSRange asterisk = [string rangeOfString:@"*"];
    return asterisk.location == 0 ? [string substringFromIndex:1] : string;
}

There are many different things you can do when dealing with responsive tables.

I personally like this approach by Chris Coyier:

• http://css-tricks.com/responsive-data-tables/

You can find many other alternatives here:

• http://css-tricks.com/responsive-data-table-roundup/
• http://bradfrost.github.io/this-is-responsive/patterns.html#tables

If you can leverage Bootstrap and get something quickly, you can simply use the class names ".hidden-phone" and ".hidden-tablet" to hide some rows but this approach might to be the best in many cases. More info (see "Responsive utility classes"):

• http://twitter.github.io/bootstrap/scaffolding.html#responsive

In my case setting AppPool->AdvancedSettings->Maximum Worker Proccesses to 1 helped.

You can replicate those brackets in the left join:

LEFT JOIN bookings  
               ON rooms.id = bookings.room_type_id
              AND (  bookings.arrival between ? and ?
                  OR bookings.departure between ? and ? )

is

->leftJoin('bookings', function($join){
    $join->on('rooms.id', '=', 'bookings.room_type_id');
    $join->on(DB::raw('(  bookings.arrival between ? and ? OR bookings.departure between ? and ? )'), DB::raw(''), DB::raw(''));
})

You'll then have to set the bindings later using "setBindings" as described in this SO post: How to bind parameters to a raw DB query in Laravel that's used on a model?

It's not pretty but it works.

Run the cmd as run as administrator this worked for me

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

Just update your eclipse.ini file (you can find it in the root-directory of eclipse) by this:

-vm
path/javaw.exe

for example:

-vm

Here is what i found googling around:

var fileupload = require("express-fileupload");
app.use(fileupload());

Which is pretty simple mechanism for uploads

app.post("/upload", function(req, res)
{
    var file;

    if(!req.files)
    {
        res.send("File was not found");
        return;
    }

    file = req.files.FormFieldName;  // here is the field name of the form

    res.send("File Uploaded");


});

Save only required cookies and reuse them.

    try:
        with open(cookieFile, 'rb') as f:
            print("Loading cookies...")
            session.cookies.update(pickle.load(f))

        print("Login in...")
        post = session.post(

This feature was added in Compose 1.6.

Reference: https://docs.docker.com/compose/compose-file/#args

I have been facing this issue when trying to authenticate a user using JSON Web Token. in my case it's related to authentication interceptor.

Sending a request to authenticate a user doesn't have to provide a token since it doesn't exist yet.

Check that your interceptor include this:

if (req.headers.get('No-Auth') == "True")
            return next.handle(req.clone());

And that you provide {'No-Auth':'True'} to your header's request like this:

  authenticateUser(user): Observable<any> {
    const headers = new HttpHeaders({'No-Auth':'True'});
    headers.append('Content-Type', 'application/json');
    return this.httpClient.post(`${this.apiEndpoint}/auth/authenticate`, user, {headers: headers});
  }

You may want to check out my library called DCKit.

You'd be able to make a rounded corner text view (as well as text field/button/plain UIView) from the Interface Builder directly:

It also has many other useful features, such as text fields with validation, controls with borders, dashed borders, circle and hairline views etc.

Alternatively you can use a "." instead of *, as this will take all the files in the working directory, include the folders and subfolders:

FROM ubuntu
COPY . /
RUN ls -la /

You could also use:

<body onload="focusOnInput()">
    <form name="passwordForm" action="verify.php" method="post">
        <input name="passwordInput" type="password" />
    </form>
</body>

And then in your JavaScript:

function focusOnInput() {
    document.forms["passwordForm"]["passwordInput"].focus();
}

It might be a bit of an overkill, but I wrote an extension method, so you can do a LeftJoin using the Join syntax (at least in method call notation):

persons.LeftJoin(
    phoneNumbers,
    person => person.Id,
    phoneNumber => phoneNumber.PersonId,
    (person, phoneNumber) => new
        {
            Person = person,
            PhoneNumber = phoneNumber?.Number
        }
);

My code does nothing more than adding a GroupJoin and a SelectMany call to the current expression tree. Nevertheless, it looks pretty complicated because I have to build the expressions myself and modify the expression tree specified by the user in the resultSelector parameter to keep the whole tree translatable by LINQ-to-Entities.

public static class LeftJoinExtension
{
    public static IQueryable<TResult> LeftJoin<TOuter, TInner, TKey, TResult>(
        this IQueryable<TOuter> outer,
        IQueryable<TInner> inner,
        Expression<Func<TOuter, TKey>> outerKeySelector,
        Expression<Func<TInner, TKey>> innerKeySelector,
        Expression<Func<TOuter, TInner, TResult>> resultSelector)

        MethodInfo groupJoin = typeof (Queryable).GetMethods()
                                                 .Single(m => m.ToString() == "System.Linq.IQueryable`1[TResult] GroupJoin[TOuter,TInner,TKey,TResult](System.Linq.IQueryable`1[TOuter], System.Collections.Generic.IEnumerable`1[TInner], System.Linq.Expressions.Expression`1[System.Func`2[TOuter,TKey]], System.Linq.Expressions.Expression`1[System.Func`2[TInner,TKey]], System.Linq.Expressions.Expression`1[System.Func`3[TOuter,System.Collections.Generic.IEnumerable`1[TInner],TResult]])")
                                                 .MakeGenericMethod(typeof (TOuter), typeof (TInner), typeof (TKey), typeof (LeftJoinIntermediate<TOuter, TInner>));
        MethodInfo selectMany = typeof (Queryable).GetMethods()

        var groupJoinResultSelector = (Expression<Func<TOuter, IEnumerable<TInner>, LeftJoinIntermediate<TOuter, TInner>>>)
                                      ((oneOuter, manyInners) => new LeftJoinIntermediate<TOuter, TInner> {OneOuter = oneOuter, ManyInners = manyInners});

        MethodCallExpression exprGroupJoin = Expression.Call(groupJoin, outer.Expression, inner.Expression, outerKeySelector, innerKeySelector, groupJoinResultSelector);

        var selectManyCollectionSelector = (Expression<Func<LeftJoinIntermediate<TOuter, TInner>, IEnumerable<TInner>>>)
                                           (t => t.ManyInners.DefaultIfEmpty());

        ParameterExpression paramUser = resultSelector.Parameters.First();

        ParameterExpression paramNew = Expression.Parameter(typeof (LeftJoinIntermediate<TOuter, TInner>), "t");
        MemberExpression propExpr = Expression.Property(paramNew, "OneOuter");

        LambdaExpression selectManyResultSelector = Expression.Lambda(new Replacer(paramUser, propExpr).Visit(resultSelector.Body), paramNew, resultSelector.Parameters.Skip(1).First());

        MethodCallExpression exprSelectMany = Expression.Call(selectMany, exprGroupJoin, selectManyCollectionSelector, selectManyResultSelector);

        return outer.Provider.CreateQuery<TResult>(exprSelectMany);
    }

    private class LeftJoinIntermediate<TOuter, TInner>
    {
        public TOuter OneOuter { get; set; }
        public IEnumerable<TInner> ManyInners { get; set; }
    }

    private class Replacer : ExpressionVisitor
    {
        private readonly ParameterExpression _oldParam;
        private readonly Expression _replacement;

        public Replacer(ParameterExpression oldParam, Expression replacement)
        {
            _oldParam = oldParam;
            _replacement = replacement;
        }

        public override Expression Visit(Expression exp)
        {
            if (exp == _oldParam)
            {
                return _replacement;
            }

            return base.Visit(exp);
        }
    }
}

This will Help to Keep a fixed length when you want to print several elements at one print statement

25s format a string with 25 spaces, left justified by default

5d format an integer reserving 5 spaces, right justified by default

members=["Niroshan","Brayan","Kate"]
print("__________________________________________________________________")
print('{:25s} {:32s} {:35s} '.format("Name","Country","Age"))
print("__________________________________________________________________")
print('{:25s} {:30s} {:5d} '.format(members[0],"Srilanka",20))
print('{:25s} {:30s} {:5d} '.format(members[1],"Australia",25))
print('{:25s} {:30s} {:5d} '.format(members[2],"England",30))
print("__________________________________________________________________")

25s format a string with 25 spaces, left justified by default

5d format an integer reserving 5 spaces, right justified by default

And this will print

__________________________________________________________________
Name                      Country                          Age
__________________________________________________________________

Kate                      England                           30
__________________________________________________________________

convert into string and then you can count tatal no of digit by .length method. Like:

String numberString = "855865264".toString();
int NumLen = numberString .Length;

it's as simple as not using a table for markup, as stated by Harmen. You're not displaying data after all, you're collecting data.

I'll take for example the question 23 here: http://accessible.netscouts-ggmbh.eu/en/developer.html#fb1_22_5

On paper, it's good as it is. If you had to display the results, it'd probably be OK.
But you can replace it with ... 4 paragraphs with a label and a select (option's would be the headers of the first line). One paragraph per line, this is far more simple.

JavaScript Pure:

<script type="text/javascript">
document.getElementById("modal").click();
</script>

JQuery:

<script type="text/javascript">
$(document).ready(function(){
    $("#modal").trigger('click'); 
});
</script>

or

<script type="text/javascript">
$(document).ready(function(){
    $("#modal").click(); 
});
</script>

Update August 2020

As mentioned originally in this answer by SoBeRich, and in my own answer, as of git 2.4.x

git push --atomic origin <branch name> <tag>

(Note: this actually work with HTTPS only with Git 2.24)

Update May 2015

As of git 2.4.1, you can do

git config --global push.followTags true

If set to true enable --follow-tags option by default.
You may override this configuration at time of push by specifying --no-follow-tags.

As noted in this thread by Matt Rogers answering Wes Hurd:

--follow-tags only pushes annotated tags.

git tag -a -m "I'm an annotation" <tagname>

That would be pushed (as opposed to git tag <tagname>, a lightweight tag, which would not be pushed, as I mentioned here)

Update April 2013

Since git 1.8.3 (April 22d, 2013), you no longer have to do 2 commands to push branches, and then to push tags:

The new "--follow-tags" option tells "git push" to push relevant annotated tags when pushing branches out.

You can now try, when pushing new commits:

git push --follow-tags

That won't push all the local tags though, only the one referenced by commits which are pushed with the git push.

Git 2.4.1+ (Q2 2015) will introduce the option push.followTags: see "How to make “git push” include tags within a branch?".

Original answer, September 2010

The nuclear option would be git push --mirror, which will push all refs under refs/.

You can also push just one tag with your current branch commit:

git push origin : v1.0.0 

You can combine the --tags option with a refspec like:

git push origin --tags :

(since --tags means: All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line)

You also have this entry "Pushing branches and tags with a single "git push" invocation"

A handy tip was just posted to the Git mailing list by Zoltán Füzesi:

I use .git/config to solve this:

[remote "origin"]
    url = ...
    fetch = +refs/heads/*:refs/remotes/origin/*
    push = +refs/heads/*
    push = +refs/tags/*

With these lines added git push origin will upload all your branches and tags. If you want to upload only some of them, you can enumerate them.

Haven't tried it myself yet, but it looks like it might be useful until some other way of pushing branches and tags at the same time is added to git push.
On the other hand, I don't mind typing:

$ git push && git push --tags

Beware, as commented by Aseem Kishore

push = +refs/heads/* will force-pushes all your branches.

This bit me just now, so FYI.

René Scheibe adds this interesting comment:

The --follow-tags parameter is misleading as only tags under .git/refs/tags are considered.
If git gc is run, tags are moved from .git/refs/tags to .git/packed-refs. Afterwards git push --follow-tags ... does not work as expected anymore.

Like a dum-dum I couldn't figure out why none of these answers were working for my Kotlin files for java.util.*, so if this is happening to you then:

Preferences
> Editor
> Code Style
> **Kotlin**
> Imports
> Packages to Use Import with '*'
-> Remove 'java.util.*'

Note if you're already using Lodash you can use the property or get functions:

var obj = { a: { b: '1', c: '2' } };
_.property('a.b')(obj); // => 1
_.get(obj, 'a.b'); // => 1

Underscore also has a property function but it doesn't support dot notation.

I like the following because it is one line. Not perfect with DST changes but usually good enough for my needs.

var fiveDaysAgo = new Date(new Date() - (1000*60*60*24*5));

I had the same error, but in my case the problem was that my application was using multiple first-level domains, while the cookie was using one. Removing cookie_domain: ".%domain%" from framework.session in the config.yml caused cookies to default to whatever domain the form was on, and that fixed the problem.

For a completely stateless utility class in Java, I suggest the class be declared public and final, and have a private constructor to prevent instantiation. The final keyword prevents sub-classing and can improve efficiency at runtime.

The class should contain all static methods and should not be declared abstract (as that would imply the class is not concrete and has to be implemented in some way).

The class should be given a name that corresponds to its set of provided utilities (or "Util" if the class is to provide a wide range of uncategorized utilities).

The class should not contain a nested class unless the nested class is to be a utility class as well (though this practice is potentially complex and hurts readability).

Methods in the class should have appropriate names.

Methods only used by the class itself should be private.

The class should not have any non-final/non-static class fields.

The class can also be statically imported by other classes to improve code readability (this depends on the complexity of the project however).

Example:

public final class ExampleUtilities {
    // Example Utility method
    public static int foo(int i, int j) {
        int val;

        //Do stuff

        return val;
    }

    // Example Utility method overloaded
    public static float foo(float i, float j) {
        float val;

        //Do stuff

        return val;
    }

    // Example Utility method calling private method
    public static long bar(int p) {
        return hid(p) * hid(p);
    }

    // Example private method
    private static long hid(int i) {
        return i * 2 + 1;
    }
}

Perhaps most importantly of all, the documentation for each method should be precise and descriptive. Chances are methods from this class will be used very often and its good to have high quality documentation to complement the code.

I know the question was about postgresql version 8 but I wrote this simple way here for people who want to get sequences in version 10 and upper

you can use the bellow query

select * from pg_sequences

view-pg-sequences

Just like said Ibam, engineStrict is now deprecated. But I've found this solution:

check-version.js:

import semver from 'semver';
import { engines } from './package';

const version = engines.node;
if (!semver.satisfies(process.version, version)) {
  console.log(`Required node version ${version} not satisfied with current version ${process.version}.`);
  process.exit(1);
}

package.json:

{
  "name": "my package",
  "engines": {
    "node": ">=50.9" // intentionally so big version number
  },
  "scripts": {
    "requirements-check": "babel-node check-version.js",
    "postinstall": "npm run requirements-check"
  }
}

Find out more here: https://medium.com/@adambisek/how-to-check-minimum-required-node-js-version-4a78a8855a0f#.3oslqmig4

.nvmrc

And one more thing. A dotfile '.nvmrc' can be used for requiring specific node version - https://github.com/creationix/nvm#nvmrc

But, it is only respected by npm scripts (and yarn scripts).

Just in file /etc/phpmyadmin/config.inc.php, uncomment or add the line(if not there),

$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

It works just Awesome!

if you have any doubt restart apache.

sudo /etc/init.d/apache2 restart

Cheers!!!

Arrays:

{{#each array}}
    {{@index}}: {{this}}
{{/each}}

If you have arrays of objects... you can iterate through the children:

{{#each array}}
    //each this = { key: value, key: value, ...}
    {{#each this}}
        //each key=@key and value=this of child object 
        {{@key}}: {{this}}
        //Or get index number of parent array looping
        {{@../index}}
    {{/each}}
{{/each}}

Objects:

{{#each object}}
    {{@key}}: {{this}}
{{/each}} 

If you have nested objects you can access the key of parent object with {{@../key}}

You can execute it just as you select a table using SELECT clause. In addition you can provide parameters within parentheses.

Try with below syntax:

SELECT * FROM yourFunctionName(parameter1, parameter2)

For me I had to put the whole interval in single quotes not just the value of the interval.

select id,  
   title,
   created_at + interval '1 day' * claim_window as deadline from projects   

Instead of

select id,  
   title,
   created_at + interval '1' day * claim_window as deadline from projects   

Postgres Date/Time Functions

My error was calling NgbModal open method with incorrect parameters from .html

Call the materialize css jquery code only after the html has rendered. So you can have a controller and then fire a service which calls the jquery code in the controller. This will render the select button alright. How ever if you try to use ngChange or ngSubmit it may not work due to the dynamic styling of the select tag.

You can take advantage of CSCRIPT.EXE or WSCRIPT.EXE (which have been present in every version of Windows since, I believe, Windows 95) like this:

echo msgbox "Hey! Here is a message!" > %tmp%\tmp.vbs
cscript /nologo %tmp%\tmp.vbs
del %tmp%\tmp.vbs

or

echo msgbox "Hey! Here is a message!" > %tmp%\tmp.vbs
wscript %tmp%\tmp.vbs
del %tmp%\tmp.vbs

You could also choose the more customizeable PopUp command. This example gives you a 10 second window to click OK, before timing out:

echo set WshShell = WScript.CreateObject("WScript.Shell") > %tmp%\tmp.vbs
echo WScript.Quit (WshShell.Popup( "You have 10 seconds to Click 'OK'." ,10 ,"Click OK", 0)) >> %tmp%\tmp.vbs
cscript /nologo %tmp%\tmp.vbs
if %errorlevel%==1 (
  echo You Clicked OK
) else (
  echo The Message timed out.
)
del %tmp%\tmp.vbs

In their above context, both cscript and wscript will act the same. When called from a batch file, bot cscript and wscript will pause the batch file until they finish their script, then allow the file to continue.

When called manually from the command prompt, cscript will not return control to the command prompt until it is finished, while wscript will create a seprate thread for the execution of it's script, returning control to the command prompt even before it's script has finished.

Other methods discussed in this thread do not cause the execution of batch files to pause while waiting for the message to be clicked on. Your selection will be dictated by your needs.

Note: Using this method, multiple button and icon configurations are available to cover various yes/no/cancel/abort/retry queries to the user: https://technet.microsoft.com/en-us/library/ee156593.aspx

regards,

To explain the two concepts by example, imagine you have an order entry system for a bookstore. The mapping of orders to items is many to many (n:m) because each order can have multiple items, and each item can be ordered by multiple orders. On the other hand, a lookup between customers and order is one to many (1:n) because a customer can place more than one order, but an order is never for more than one customer.

This function returns the approximate screen size in inches.

public double getScreenSize()
{
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int width=dm.widthPixels;
        int height=dm.heightPixels;
        int dens=dm.densityDpi;
        double wi=(double)width/(double)dens;
        double hi=(double)height/(double)dens;
        double x = Math.pow(wi,2);
        double y = Math.pow(hi,2);
        double screenInches = Math.sqrt(x+y);
        return screenInches;
}

This should work for both strings and unicode objects in Python2, and both strings and bytes in Python3:

# python <3.0
def only_numerics(seq):
    return filter(type(seq).isdigit, seq)

# python =3.0
def only_numerics(seq):
    seq_type= type(seq)
    return seq_type().join(filter(seq_type.isdigit, seq))

    // no_roundUp(n,b) ( (n)+(b) - (n)%(b) )

                { m = roundUp(17,8); } ++m;
    assertTrue( 24 == roundUp(17,8) );
                { m = roundUp(24,8); }

    assertTrue( 20 == roundUp(17,4) );

Once the array size is fixed while running the program ,it's size can't be changed further. So better go for ArrayList while dealing with dynamic arrays.

All the info is in the other answers, but none summarizes both your requests or seem to make things needlessly complex:

• For your removal needs use:

  pip uninstall <package>
  

  (install using easy_install pip)

• For your 'list installed packages' needs either use:

  pip freeze
  

  Or:

  yolk -l
  

  which can output more package details.

  (Install via easy_install yolk or pip install yolk)

Different way to do multi-threading and Asynchronous in JavaScript

Before HTML5 JavaScript only allowed the execution of one thread per page.

There was some hacky way to simulate an asynchronous execution with Yield, setTimeout(), setInterval(), XMLHttpRequest or event handlers (see the end of this post for an example with yield and setTimeout()).

But with HTML5 we can now use Worker Threads to parallelize the execution of functions. Here is an example of use.

Real multi-threading

Multi-threading: JavaScript Worker Threads

HTML5 introduced Web Worker Threads (see: browsers compatibilities)
Note: IE9 and earlier versions do not support it.

These worker threads are JavaScript threads that run in background without affecting the performance of the page. For more information about Web Worker read the documentation or this tutorial.

Here is a simple example with 3 Web Worker threads that count to MAX_VALUE and show the current computed value in our page:

//As a worker normally take another JavaScript file to execute we convert the function in an URL: http://stackoverflow.com/a/16799132/2576706_x000D_
function getScriptPath(foo){ return window.URL.createObjectURL(new Blob([foo.toString().match(/^\s*function\s*\(\s*\)\s*\{(([\s\S](?!\}$))*[\s\S])/)[1]],{type:'text/javascript'})); }_x000D_
_x000D_
var MAX_VALUE = 10000;_x000D_
_x000D_
/*_x000D_
 * Here are the workers_x000D_
 */_x000D_
//Worker 1_x000D_
var worker1 = new Worker(getScriptPath(function(){_x000D_
    self.addEventListener('message', function(e) {_x000D_
        var value = 0;_x000D_
        while(value <= e.data){_x000D_
            self.postMessage(value);_x000D_
            value++;_x000D_
        }_x000D_
    }, false);_x000D_
}));_x000D_
//We add a listener to the worker to get the response and show it in the page_x000D_
worker1.addEventListener('message', function(e) {_x000D_
  document.getElementById("result1").innerHTML = e.data;_x000D_
}, false);_x000D_
_x000D_
_x000D_
//Worker 2_x000D_
var worker2 = new Worker(getScriptPath(function(){_x000D_
    self.addEventListener('message', function(e) {_x000D_
        var value = 0;_x000D_
        while(value <= e.data){_x000D_
            self.postMessage(value);_x000D_
            value++;_x000D_
        }_x000D_
    }, false);_x000D_
}));_x000D_
worker2.addEventListener('message', function(e) {_x000D_
  document.getElementById("result2").innerHTML = e.data;_x000D_
}, false);_x000D_
_x000D_
_x000D_
//Worker 3_x000D_
var worker3 = new Worker(getScriptPath(function(){_x000D_
    self.addEventListener('message', function(e) {_x000D_
        var value = 0;_x000D_
        while(value <= e.data){_x000D_
            self.postMessage(value);_x000D_
            value++;_x000D_
        }_x000D_
    }, false);_x000D_
}));_x000D_
worker3.addEventListener('message', function(e) {_x000D_
    document.getElementById("result3").innerHTML = e.data;_x000D_
}, false);_x000D_
_x000D_
_x000D_
// Start and send data to our worker._x000D_
worker1.postMessage(MAX_VALUE); _x000D_
worker2.postMessage(MAX_VALUE); _x000D_
worker3.postMessage(MAX_VALUE);

<div id="result1"></div>_x000D_
<div id="result2"></div>_x000D_
<div id="result3"></div>

We can see that the three threads are executed in concurrency and print their current value in the page. They don't freeze the page because they are executed in the background with separated threads.

Multi-threading: with multiple iframes

Another way to achieve this is to use multiple iframes, each one will execute a thread. We can give the iframe some parameters by the URL and the iframe can communicate with his parent in order to get the result and print it back (the iframe must be in the same domain).

This example doesn't work in all browsers! iframes usually run in the same thread/process as the main page (but Firefox and Chromium seem to handle it differently).

Since the code snippet does not support multiple HTML files, I will just provide the different codes here:

index.html:

//The 3 iframes containing the code (take the thread id in param)
<iframe id="threadFrame1" src="thread.html?id=1"></iframe>
<iframe id="threadFrame2" src="thread.html?id=2"></iframe>
<iframe id="threadFrame3" src="thread.html?id=3"></iframe>

//Divs that shows the result
<div id="result1"></div>
<div id="result2"></div>
<div id="result3"></div>


<script>
    //This function is called by each iframe
    function threadResult(threadId, result) {
        document.getElementById("result" + threadId).innerHTML = result;
    }
</script>

thread.html:

//Get the parameters in the URL: http://stackoverflow.com/a/1099670/2576706
function getQueryParams(paramName) {
    var qs = document.location.search.split('+').join(' ');
    var params = {}, tokens, re = /[?&]?([^=]+)=([^&]*)/g;
    while (tokens = re.exec(qs)) {
        params[decodeURIComponent(tokens[1])] = decodeURIComponent(tokens[2]);
    }
    return params[paramName];
}

//The thread code (get the id from the URL, we can pass other parameters as needed)
var MAX_VALUE = 100000;
(function thread() {
    var threadId = getQueryParams('id');
    for(var i=0; i<MAX_VALUE; i++){
        parent.threadResult(threadId, i);
    }
})();

Simulate multi-threading

Single-thread: emulate JavaScript concurrency with setTimeout()

The 'naive' way would be to execute the function setTimeout() one after the other like this:

setTimeout(function(){ /* Some tasks */ }, 0);
setTimeout(function(){ /* Some tasks */ }, 0);
[...]

But this method does not work because each task will be executed one after the other.

We can simulate asynchronous execution by calling the function recursively like this:

var MAX_VALUE = 10000;_x000D_
_x000D_
function thread1(value, maxValue){_x000D_
    var me = this;_x000D_
    document.getElementById("result1").innerHTML = value;_x000D_
    value++;_x000D_
  _x000D_
    //Continue execution_x000D_
    if(value<=maxValue)_x000D_
        setTimeout(function () { me.thread1(value, maxValue); }, 0);_x000D_
}_x000D_
_x000D_
function thread2(value, maxValue){_x000D_
    var me = this;_x000D_
    document.getElementById("result2").innerHTML = value;_x000D_
    value++;_x000D_
 _x000D_
    if(value<=maxValue)_x000D_
        setTimeout(function () { me.thread2(value, maxValue); }, 0);_x000D_
}_x000D_
_x000D_
function thread3(value, maxValue){_x000D_
    var me = this;_x000D_
    document.getElementById("result3").innerHTML = value;_x000D_
    value++;_x000D_
 _x000D_
    if(value<=maxValue)_x000D_
        setTimeout(function () { me.thread3(value, maxValue); }, 0);_x000D_
}_x000D_
_x000D_
thread1(0, MAX_VALUE);_x000D_
thread2(0, MAX_VALUE);_x000D_
thread3(0, MAX_VALUE);

<div id="result1"></div>_x000D_
<div id="result2"></div>_x000D_
<div id="result3"></div>

As you can see this second method is very slow and freezes the browser because it uses the main thread to execute the functions.

Single-thread: emulate JavaScript concurrency with yield

Yield is a new feature in ECMAScript 6, it only works on the oldest version of Firefox and Chrome (in Chrome you need to enable Experimental JavaScript appearing in chrome://flags/#enable-javascript-harmony).

The yield keyword causes generator function execution to pause and the value of the expression following the yield keyword is returned to the generator's caller. It can be thought of as a generator-based version of the return keyword.

A generator allows you to suspend execution of a function and resume it later. A generator can be used to schedule your functions with a technique called trampolining.

Here is the example:

var MAX_VALUE = 10000;_x000D_
_x000D_
Scheduler = {_x000D_
 _tasks: [],_x000D_
 add: function(func){_x000D_
  this._tasks.push(func);_x000D_
 }, _x000D_
 start: function(){_x000D_
  var tasks = this._tasks;_x000D_
  var length = tasks.length;_x000D_
  while(length>0){_x000D_
   for(var i=0; i<length; i++){_x000D_
    var res = tasks[i].next();_x000D_
    if(res.done){_x000D_
     tasks.splice(i, 1);_x000D_
     length--;_x000D_
     i--;_x000D_
    }_x000D_
   }_x000D_
  }_x000D_
 } _x000D_
}_x000D_
_x000D_
_x000D_
function* updateUI(threadID, maxValue) {_x000D_
  var value = 0;_x000D_
  while(value<=maxValue){_x000D_
 yield document.getElementById("result" + threadID).innerHTML = value;_x000D_
 value++;_x000D_
  }_x000D_
}_x000D_
_x000D_
Scheduler.add(updateUI(1, MAX_VALUE));_x000D_
Scheduler.add(updateUI(2, MAX_VALUE));_x000D_
Scheduler.add(updateUI(3, MAX_VALUE));_x000D_
_x000D_
Scheduler.start()

<div id="result1"></div>_x000D_
<div id="result2"></div>_x000D_
<div id="result3"></div>

Unfortunately, Xcode doesn't have anything nearly as extensive as VS or Jalopy for Eclipse available. There are SOME disparate features, such as Structure > Re-Indent as well as the auto-formatting used when you paste code into your source file. I am totally with you, though; there definitely should be something in there to help with formatting issues.

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

I had similar problems for one of my projects to create a URI object from a string. I couldn't find any clean solution either. Here's what I came up with :

public static URI encodeURL(String url) throws MalformedURLException, URISyntaxException  
{
    URI uriFormatted = null; 

    URL urlLink = new URL(url);
    uriFormatted = new URI("http", urlLink.getHost(), urlLink.getPath(), urlLink.getQuery(), urlLink.getRef());

    return uriFormatted;
}

You can use the following URI constructor instead to specify a port if needed:

URI uri = new URI(scheme, userInfo, host, port, path, query, fragment);

select sum([rows])
from sys.partitions
where object_id=object_id('tablename')
 and index_id in (0,1)

is very fast but very rarely inaccurate.

I agree with Cade Roux.

This article should get you on the right track:

• Indexes in SQL Server 2005/2008 – Best Practices, Part 1
• Indexes in SQL Server 2005/2008 – Part 2 – Internals

One thing to note, clustered indexes should have a unique key (an identity column I would recommend) as the first column. Basically it helps your data insert at the end of the index and not cause lots of disk IO and Page splits.

Secondly, if you are creating other indexes on your data and they are constructed cleverly they will be reused.

e.g. imagine you search a table on three columns

state, county, zip.

• you sometimes search by state only.
• you sometimes search by state and county.
• you frequently search by state, county, zip.

Then an index with state, county, zip. will be used in all three of these searches.

If you search by zip alone quite a lot then the above index will not be used (by SQL Server anyway) as zip is the third part of that index and the query optimiser will not see that index as helpful.

You could then create an index on Zip alone that would be used in this instance.

By the way We can take advantage of the fact that with Multi-Column indexing the first index column is always usable for searching and when you search only by 'state' it is efficient but yet not as efficient as Single-Column index on 'state'

I guess the answer you are looking for is that it depends on your where clauses of your frequently used queries and also your group by's.

The article will help a lot. :-)

For separation of concern, I would suggest you use action filter for model validation, so you don't need to care much how to do validation in your api controller:

using System.Net;
using System.Net.Http;
using System.Web.Http.Controllers;
using System.Web.Http.Filters;

namespace System.Web.Http.Filters
{
    public class ValidationActionFilter : ActionFilterAttribute
    {
        public override void OnActionExecuting(HttpActionContext actionContext)
        {
            var modelState = actionContext.ModelState;

            if (!modelState.IsValid)
                actionContext.Response = actionContext.Request
                     .CreateErrorResponse(HttpStatusCode.BadRequest, modelState);
        }
    }
}

                        //Save the Watermarked image to the MemoryStream.
                        bmp.Save(memoryStream, ImageFormat.Png);
                        memoryStream.Position = 0;
                       // string fileName = Path.GetFileNameWithoutExtension(filePath);
                        // outPuthFilePath = Path.Combine(Path.GetDirectoryName(filePath), fileName + "_outputh.png");
                        using (FileStream file = new FileStream(filePath, FileMode.Create, System.IO.FileAccess.Write))
                        {
                            byte[] bytes = new byte[memoryStream.Length];
                            memoryStream.Read(bytes, 0, (int)memoryStream.Length);
                            file.Write(bytes, 0, bytes.Length);
                            memoryStream.Close();
                        }
                    }
                }
            }

        }
    }

I wanted to add a very simple workflow from someone who has been frustrated with git in the past. There are several ways to use git, probably the most common for unity are GitHub Desktop, Git Bash and GitHub Unity

https://assetstore.unity.com/packages/tools/version-control/github-for-unity-118069.

Essentially they all do the same thing but its user choice. You can have git for large file setup which allows 1GB free large file storage with additional storage available in data packs for $4/mo for 50GB, and this will allow you to push files >100mb to remote repositories (it stores the actual files on a server and in your repo a pointer)

https://git-lfs.github.com/

If you don't want to setup lfs for whatever reason you can scan your projects for files > 128 mb in windows by typing size:large in the directory where you have your project. This can be handy to search for large files, although there may be some files between 100mb and 128mb that get missed.

The general format of git bash is

git add . (adds files to be commited)

git commit -m 'message' (commits the files with a message, they are still on your pc and not in the remote repo, basically they have been 'versioned' as a new commit)

git push (push files to the repository)

The disadvantage of git bash for unity projects is that if there is a file > 100mb, you won't get an error until you push. You then have to undo your commit by resetting your head to the previous commit. Kind of a hassle, especially if you are new with git bash.

The advantage of GitHub Desktop, is BEFORE you commit files with 100mb it will give you a popup error message. You can then shrink those files or add them to a .gitignore file.

To use a .gitignore file, create a file called .gitignore in your local repository root directory. Simply add the files one line at a time you would like to omit. SharedAssets and other non-Asset folder files can usually be omitted and will automatically repopulate in the editor (packages can be re-imported etc). You can also use wildcards to exclude file types.

If other people are using your GitHub repo and you want to clone or pull you have those options available to you as well on GitHub desktop or Git bash.

I did not mention much about Unity GitHub package where you can use GitHub in the editor because personally I did not find the interface very useful, and I don't think overall its going to help anyone get familiar with git, but this is just my preference.

It turns out this can be nicely expressed in a vectorized fashion:

> df = pd.DataFrame({'a':[0,0,1,1], 'b':[0,1,0,1]})
> df = df[(df.T != 0).any()]
> df
   a  b
1  0  1
2  1  0
3  1  1

As EBGreen said, [System.Diagnostics.FileVersionInfo]::GetVersionInfo(path) will work, but remember that you can also get all the members of FileVersionInfo, for example:

[System.Diagnostics.FileVersionInfo]::GetVersionInfo(path).CompanyName

You should be able to use every member of FileVersionInfo documented here, which will get you basically anything you could ever want about the file.

if x == 80 or x == 443 or 1024 <= x <= 65535

should definitely do

This works for me in irb:

irb> (1..4).to_a
=> [1, 2, 3, 4]

I notice that:

irb> 1..4.to_a
(irb):1: warning: default `to_a' will be obsolete
ArgumentError: bad value for range
        from (irb):1

So perhaps you are missing the parentheses?

(I am running Ruby 1.8.6 patchlevel 114)

Use the Node.js console.time() and console.timeEnd():

var i;
console.time("dbsave");

for(i = 1; i < LIMIT; i++){
    db.users.save({id : i, name : "MongoUser [" + i + "]"}, end);
}

end = function(err, saved) {
    console.log(( err || !saved )?"Error":"Saved");
    if(--i === 1){console.timeEnd("dbsave");}
};

Another way of doing it. This approach can be useful for changing the text to 2 different colors, just by adding 2 spans.

Label1.Text = "String with original color" + "<b><span style=""color:red;"">" + "Your String Here" + "</span></b>";

Another workaround for those who don't need the entire shebang: use the switch

-DBOOST_ERROR_CODE_HEADER_ONLY.

If you use CMake, it's add_definitions(-DBOOST_ERROR_CODE_HEADER_ONLY).

You can get the "computed" styles of any element.

IE uses something called "currentStyle", Firefox (and I assume other "standard compliant" browsers) uses "defaultView.getComputedStyle".

You'll need to write a cross browser function to do this, or use a good Javascript framework like prototype or jQuery (search for "getStyle" in the prototype javascript file, and "curCss" in the jquery javascript file).

That said if you need the height or width you should probably use element.offsetHeight and element.offsetWidth.

The value returned is Null, so if I have Javascript that needs to know the width of something to do some logic (I increase the width by 1%, not to a specific value)

Mind, if you add an inline style to the element in question, it can act as the "default" value and will be readable by Javascript on page load, since it is the element's inline style property:

<div style="width:50%">....</div>

I followed @Viktor Kerkez's answer and have had mixed success. I found that sometimes this recipe of

conda skeleton pypi PACKAGE

conda build PACKAGE

would look like everything worked but I could not successfully import PACKAGE. Recently I asked about this on the Anaconda user group and heard from @Travis Oliphant himself on the best way to use conda to build and manage packages that do not ship with Anaconda. You can read this thread here, but I'll describe the approach below to hopefully make the answers to the OP's question more complete...

Example: I am going to install the excellent prettyplotlib package on Windows using conda 2.2.5.

1a) conda build --build-recipe prettyplotlib

You'll see the build messages all look good until the final TEST section of the build. I saw this error

File "C:\Anaconda\conda-bld\test-tmp_dir\run_test.py", line 23 import None SyntaxError: cannot assign to None TESTS FAILED: prettyplotlib-0.1.3-py27_0

1b) Go into /conda-recipes/prettyplotlib and edit the meta.yaml file. Presently, the packages being set up like in step 1a result in yaml files that have an error in the test section. For example, here is how mine looked for prettyplotlib

test:   # Python imports   imports:
    - 
    - prettyplotlib
    - prettyplotlib

Edit this section to remove the blank line preceded by the - and also remove the redundant prettyplotlib line. At the time of this writing I have found that I need to edit most meta.yaml files like this for external packages I am installing with conda, meaning that there is a blank import line causing the error along with a redundant import of the given package.

1c) Rerun the command from 1a, which should complete with out error this time. At the end of the build you'll be asked if you want to upload the build to binstar. I entered No and then saw this message:

If you want to upload this package to binstar.org later, type:

$ binstar upload C:\Anaconda\conda-bld\win-64\prettyplotlib-0.1.3-py27_0.tar.bz2

That tar.bz2 file is the build that you now need to actually install.

2) conda install C:\Anaconda\conda-bld\win-64\prettyplotlib-0.1.3-py27_0.tar.bz2

Following these steps I have successfully used conda to install a number of packages that do not come with Anaconda. Previously, I had installed some of these using pip, so I did pip uninstall PACKAGE prior to installing PACKAGE with conda. Using conda, I can now manage (almost) all of my packages with a single approach rather than having a mix of stuff installed with conda, pip, easy_install, and python setup.py install.

For context, I think this recent blog post by @Travis Oliphant will be helpful for people like me who do not appreciate everything that goes into robust Python packaging but certainly appreciate when stuff "just works". conda seems like a great way forward...

I had this code in a fragment and it was crashing if I try to come back to this fragment

if (mRootView == null) {
    mRootView = inflater.inflate(R.layout.fragment_main, container, false);
} 

after gathering the answers on this thread, I realised that mRootView's parent still have mRootView as child. So, this was my fix.

if (mRootView == null) {
    mRootView = inflater.inflate(R.layout.fragment_main, container, false);
} else {
    ((ViewGroup) mRootView.getParent()).removeView(mRootView);
}

hope this helps

Here is a better implementation of an "every 10th item" list comprehension, that does not use the list contents as part of the membership test:

>>> l = range(165)
>>> [ item for i,item in enumerate(l) if i%10==0 ]
[0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160]
>>> l = list("ABCDEFGHIJKLMNOPQRSTUVWXYZ")
>>> [ item for i,item in enumerate(l) if i%10==0 ]
['A', 'K', 'U']

But this is still far slower than just using list slicing.

You're comparing the message with the empty string using ==.

First, your comparison is wrong because the message will be null (and not the empty string).

Second, it's wrong because Objects must be compared with equals() and not with ==.

Third, it's wrong because you should avoid scriptlets in JSP, and use the JSP EL, the JSTL, and other custom tags instead:

<c:id test="${!empty message}">
    <c:out value="${message}"/>
</c:if>

If you can't use JodaTime, you can do the following:

Calendar startCalendar = new GregorianCalendar();
startCalendar.setTime(startDate);
Calendar endCalendar = new GregorianCalendar();
endCalendar.setTime(endDate);

int diffYear = endCalendar.get(Calendar.YEAR) - startCalendar.get(Calendar.YEAR);
int diffMonth = diffYear * 12 + endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);

Note that if your dates are 2013-01-31 and 2013-02-01, you get a distance of 1 month this way, which may or may not be what you want.

Have you set the KeyStore and/or TrustStore System properties?

java -Djavax.net.ssl.keyStore=pathToKeystore -Djavax.net.ssl.keyStorePassword=123456

or from with the code

System.setProperty("javax.net.ssl.keyStore", pathToKeyStore);

Same with javax.net.ssl.trustStore

You are correct that blanks "" or a string "#N/A" are indeed interpreted as having values in excel. You need to use a function NA().

Annotations are a form of metadata (data about data) added to a Java source file. They are largely used by frameworks to simplify the integration of client code. A couple of real world examples off the top of my head:

• JUnit 4 - you add the @Test annotation to each test method you want the JUnit runner to run. There are also additional annotations to do with setting up testing (like @Before and @BeforeClass). All these are processed by the JUnit runner, which runs the tests accordingly. You could say it's an replacement for XML configuration, but annotations are sometimes more powerful (they can use reflection, for example) and also they are closer to the code they are referencing to (the @Test annotation is right before the test method, so the purpose of that method is clear - serves as documentation as well). XML configuration on the other hand can be more complex and can include much more data than annotations can.

• Terracotta - uses both annotations and XML configuration files. For example, the @Root annotation tells the Terracotta runtime that the annotated field is a root and its memory should be shared between VM instances. The XML configuration file is used to configure the server and tell it which classes to instrument.

• Google Guice - an example would be the @Inject annotation, which when applied to a constructor makes the Guice runtime look for values for each parameter, based on the defined injectors. The @Inject annotation would be quite hard to replicate using XML configuration files, and its proximity to the constructor it references to is quite useful (imagine having to search to a huge XML file to find all the dependency injections you have set up).

Hopefully I've given you a flavour of how annotations are used in different frameworks.

I defined two functions in Site.Master:

    <script type="text/javascript">
    var spinnerVisible = false;
    function showProgress() {
        if (!spinnerVisible) {
            $("div#spinner").fadeIn("fast");
            spinnerVisible = true;
        }
    };
    function hideProgress() {
        if (spinnerVisible) {
            var spinner = $("div#spinner");
            spinner.stop();
            spinner.fadeOut("fast");
            spinnerVisible = false;
        }
    };
</script>

And special section:

    <div id="spinner">
        Loading...
    </div>

Visual style is defined in CSS:

div#spinner
{
    display: none;
    width:100px;
    height: 100px;
    position: fixed;
    top: 50%;
    left: 50%;
    background:url(spinner.gif) no-repeat center #fff;
    text-align:center;
    padding:10px;
    font:normal 16px Tahoma, Geneva, sans-serif;
    border:1px solid #666;
    margin-left: -50px;
    margin-top: -50px;
    z-index:2;
    overflow: auto;
}

An abstract class is a class that you can't create an object from, so it is mostly used for inheriting from.(I am not sure if you can have static methods in it)

An abstract method is a method that the child class must override, it does not have a body, is marked abstract and only abstract classes can have those methods.

Finally got it: The way Eclipse picks up the JRE is using the system's PATH.

I did not have C:\home\SFTWR\jdk1.6.0_21\bin in the path at all before and I did have C:\Program Files (x86)\Java\jre6\bin. I had both JRE_HOME and JAVA_HOME set to C:\home\SFTWR\jdk1.6.0_21 but neither of those two mattered. I guess Eclipse did (something to the effect of) where java (or which on UNIX/Linux) to see where Java is in the path and took the JRE to which that java.exe belonged. In my case, despite all the configuration tweaks I had done (including eclipse.ini -vm option as suggested above), it remained stuck to what was in the path.

I removed the old JRE bin from the path, put the new one in, and it works for all workspaces.

Here's an excellent article by Scott Allen: Developing Gadgets for the Windows Sidebar

This site, Windows 7/Vista Sidebar Gadgets, has links to many gadget resources.

I solved the problem by adding the following dependency

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>2.2</version>
</dependency>

Together with

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jdbc</artifactId>
</dependency>

Declare them outside the subroutines, like this:

Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine
End Sub
Sub OtherSubRoutine()
    MsgBox wbA.Name, vbInformation
End Sub

Alternately, you can pass variables between subroutines:

Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
    MsgBox wb1.Name, vbInformation
    MsgBox wb2.Name, vbInformation
End Sub

Or use Functions to return values:

Sub MySubroutine()
    Dim i as Long
    i = MyFunction()
    MsgBox i
End Sub
Function MyFunction()
    'Lots of code that does something
    Dim x As Integer, y as Double
    For x = 1 to 1000
        'Lots of code that does something
    Next
    MyFunction = y
End Function

In the second method, within the scope of OtherSubRoutine you refer to them by their parameter names wb1 and wb2. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.

A Note About User Forms

Personally I would recommend keeping Option Explicit in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn when you meant lCount etc., among other reasons).

If you're using Option Explicit (which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public scoped variables, as these are not "public" in the same sense. For instance, i is undefined, though it's Public in the scope of UserForm1:

You can refer to it as UserForm1.i to avoid the compile error, or since forms are New-able, you can create a variable object to contain reference to your form, and refer to it that way:

NB: In the above screenshots x is declared Public x as Long in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x to avoid ambiguity and possible shadowing in case you re-use variable names...

Could it be that you have an error in your CSS file? A parenthesis left unclosed, a missing semicolon etc?

Have you tried implementing InitializingBean? It sounds like exactly what you're after.

The downside is that your bean becomes Spring-aware, but in most applications that's not so bad.

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.

There is one way to achieve this that I did not see anybody mentioning here.

By rotating the parent container by 180 degrees and the child-container again by 180 degrees the scrollbar will be shown at top

.parent {
  transform: rotateX(180deg);
  overflow-x: auto;
} 
.child {
  transform: rotateX(180deg);
}

For reference see the issue in the w3c repository.

DECLARE @sqlCommand nvarchar(1000)
DECLARE @city varchar(75)
declare @counts int
SET @city = 'New York'
SET @sqlCommand = 'SELECT @cnt=COUNT(*) FROM customers WHERE City = @city'
EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75),@cnt int OUTPUT', @city = @city, @cnt=@counts OUTPUT
select @counts as Counts

You can rewrite the code likes this:

#include<iostream>
#include<stdio.h>

using namespace std;

Assuming, that you have root access on the box you can do:

sudo -u postgres psql

If that fails with a database "postgres" does not exists this block.

sudo -u postgres psql template1

Then sudo nano /etc/postgresql/11/main/pg_hba.conf file

local   all         postgres                          ident

For newer versions of PostgreSQL ident actually might be peer.

Inside the psql shell you can give the DB user postgres a password:

ALTER USER postgres PASSWORD 'newPassword';

First convert LONG type column to CLOB type then use LIKE condition, for example:

CREATE TABLE tbl_clob AS
   SELECT to_lob(long_col) lob_col FROM tbl_long;

SELECT * FROM tbl_clob WHERE lob_col LIKE '%form%';

To get your program to run, please put jsp files under web-content and not under WEB-INF because in Eclipse the files are not accessed there by the server, so try starting the server and browsing to URL:

http://localhost:8080/YourProject/yourfile.jsp

then your problem will be solved.

*my_map.begin(). See e.g. http://cplusplus.com/reference/stl/map/begin/.

This worked for me:

ls -rt -d -1 $PWD/{*,.*}

Deferred promises are a nice way to chain together function execution neatly and easily. Whether AJAX or normal functions, they offer greater flexibility than callbacks, and I've found easier to grasp.

function Typer()
{
var dfd = $.Deferred();
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];

UPDATE :

////////////////////////////////

  var timer=    setInterval(function() {
                    if(i == srcText.length) {

    // clearInterval(this);


       clearInterval(timer);

////////////////////////////////


   dfd.resolve();
                        };
                        i++;
                        result += srcText[i].replace("\n", "<br />");
                        $("#message").html( result);
                },
                100);
              return dfd.promise();
            }

I've modified the play function so it returns a promise when the audio finishes playing, which might be useful to some. The third function fires when sound finishes playing.

   function playBGM()
    {
      var playsound = $.Deferred();
      $('#bgm')[0].play();
      $("#bgm").on("ended", function() {
         playsound.resolve();
      });
        return playsound.promise();
    }


    function thirdFunction() {
        alert('third function');
    }

Now call the whole thing with the following: (be sure to use Jquery 1.9.1 or above as I found that 1.7.2 executes all the functions at once, rather than waiting for each to resolve.)

Typer().then(playBGM).then(thirdFunction);  

Before today, I had no luck using deferred promises in this way, and finally have grasped it. Precisely timed, chained interface events occurring exactly when we want them to, including async events, has never been easy. For me at least, I now have it under control thanks largely to others asking questions here.

There are a lot of solutions, here one: if you want only number erase the letters and the method receives a random and the result length.

public String GenerateRandom(Random oRandom, int iLongitudPin)
{
    String sCharacters = "123456789ABCDEFGHIJKLMNPQRSTUVWXYZ123456789";
    int iLength = sCharacters.Length;
    char cCharacter;
    int iLongitudNuevaCadena = iLongitudPin; 
    String sRandomResult = "";
    for (int i = 0; i < iLongitudNuevaCadena; i++)
    {
        cCharacter = sCharacters[oRandom.Next(iLength)];
        sRandomResult += cCharacter.ToString();
    }
    return (sRandomResult);
}

For what purpose?

• Quickest for an IF would be IF EXISTS (SELECT * FROM Table)...
• For a result set, SELECT TOP 1 1 FROM Table returns either zero or one rows
• For exactly one row with a count (0 or non-zero), SELECT COUNT(*) FROM Table

Something like:

find /path/ -type f -exec stat \{} --printf="%y\n" \; | 
     sort -n -r | 
     head -n 1

Explanation:

• the find command will print modification time for every file recursively ignoring directories (according to the comment by IQAndreas you can't rely on the folders timestamps)
• sort -n (numerically) -r (reverse)
• head -n 1: get the first entry

Simple, just use .set_color

>>> barlist=plt.bar([1,2,3,4], [1,2,3,4])
>>> barlist[0].set_color('r')
>>> plt.show()

For your new question, not much harder either, just need to find the bar from your axis, an example:

>>> f=plt.figure()
>>> ax=f.add_subplot(1,1,1)
>>> ax.bar([1,2,3,4], [1,2,3,4])
<Container object of 4 artists>
>>> ax.get_children()
[<matplotlib.axis.XAxis object at 0x6529850>, 
 <matplotlib.axis.YAxis object at 0x78460d0>,

If you have a complex plot and want to identify the bars first, add those:

>>> import matplotlib
>>> childrenLS=ax.get_children()
>>> barlist=filter(lambda x: isinstance(x, matplotlib.patches.Rectangle), childrenLS)

If you just want the INSERT queries, use the following:

mysqldump --skip-triggers --compact --no-create-info

I had problems with elastic scrolling (scroll bouncing, rubber-banding). Ignoring the down-scroll event if close to the page top worked for me.

var position = $(window).scrollTop();
$(window).scroll(function () {
    var scroll = $(window).scrollTop();
    var downScroll = scroll > position;
    var closeToTop = -120 < scroll && scroll < 120;
    if (downScroll && !closeToTop) {
        // scrolled down and not to close to top (to avoid Ipad elastic scroll-problems)
        $('.top-container').slideUp('fast');
        $('.main-header').addClass('padding-top');
    } else {
        // scrolled up
        $('.top-container').slideDown('fast');
        $('.main-header').removeClass('padding-top');
    }
    position = scroll;
});

LinearLayout - In LinearLayout, views are organized either in vertical or horizontal orientation.

RelativeLayout - RelativeLayout is way more complex than LinearLayout, hence provides much more functionalities. Views are placed, as the name suggests, relative to each other.

FrameLayout - It behaves as a single object and its child views are overlapped over each other. FrameLayout takes the size of as per the biggest child element.

Coordinator Layout - This is the most powerful ViewGroup introduced in Android support library. It behaves as FrameLayout and has a lot of functionalities to coordinate amongst its child views, for example, floating button and snackbar, Toolbar with scrollable view.

In my case, installing nodejs-legacy solved the issue.

sudo apt-get install nodejs-legacy

You shouldn't use:

Page.Response.Redirect(Page.Request.Url.ToString(), true);

because this might cause a runtime error.

A better approach is:

Page.Response.Redirect(Page.Request.Url.ToString(), false);
        Context.ApplicationInstance.CompleteRequest();

Adding processData: false to the $.ajax options will fix this issue.

If you don't use ngRoute module, i.e. you don't have $viewContentLoaded event.

You can use another directive method:

    angular.module('someModule')
        .directive('someDirective', someDirective);

    someDirective.$inject = ['$rootScope', '$timeout']; //Inject services

    function someDirective($rootScope, $timeout){
        return {
            restrict: "A",
            priority: Number.MIN_SAFE_INTEGER, //Lowest priority
            link    : function(scope, element, attr){
                $timeout(
                    function(){
                        $rootScope.$emit("Some:event");
                    }
                );
            }
        };
    }

Accordingly to trusktr's answer it has lowest priority. Plus $timeout will cause Angular to run through an entire event loop before callback execution.

$rootScope used, because it allow to place directive in any scope of the application and notify only necessary listeners.

$rootScope.$emit will fire an event for all $rootScope.$on listeners only. The interesting part is that $rootScope.$broadcast will notify all $rootScope.$on as well as $scope.$on listeners Source

Executing a click via JavaScript has some behaviors of which you should be aware. If for example, the code bound to the onclick event of your element invokes window.alert(), you may find your Selenium code hanging, depending on the implementation of the browser driver. That said, you can use the JavascriptExecutor class to do this. My solution differs from others proposed, however, in that you can still use the WebDriver methods for locating the elements.

// Assume driver is a valid WebDriver instance that
// has been properly instantiated elsewhere.
WebElement element = driver.findElement(By.id("gbqfd"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", element);

You should also note that you might be better off using the click() method of the WebElement interface, but disabling native events before instantiating your driver. This would accomplish the same goal (with the same potential limitations), but not force you to write and maintain your own JavaScript.

Try this:

$(document).ready(function(){
    var data= $('select').find('option:selected').val();
});

or

var data= $('select').find('option:selected').text();

There are already answers which describes about window.location.href property and window.open() method.

I will go by Objective use:

1. To redirect the page to another

Use window.location.href. Set href property to the href of another page.

2. Open link in the new or specific window.

Use window.open(). Pass parameters as per your goal.

3. Know current address of the page

Use window.location.href. Get value of window.location.href property. You can also get specific protocol, hostname, hashstring from window.location object.

See Location Object for more information.

Try

 def self.search(search, page = 1 )
    paginate :per_page => 5, :page => page,
      :conditions => ["name LIKE  ? OR postal_code like ?", "%#{search}%","%#{search}%"],   order => 'name'
  end

See the docs on AREL conditions for more info.

This may helps:

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
@Override
public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
    String url = request.getUrl().toString();
    WebResourceResponse response = super.shouldInterceptRequest(view, request);
    // load native js
    if (url != null && url.contains(INJECTION_TOKEN/* scheme define */)) {

        response = new WebResourceResponse(
                "text/javascript",
                "utf-8",
                loadJsInputStream(url, JsCache.getJsFilePath(path) /* InputStream */));
    }
    return response;
}

The webpack config file (in webpack 2) allows you to export a promise chain, so long as the last step returns a webpack config object. See promise configuration docs. From there:

webpack now supports returning a Promise from the configuration file. This allows to do async processing in you configuration file.

You could create a simple recursive copy function that copies your file, and only after that triggers webpack. E.g.:

module.exports = function(){
    return copyTheFiles( inpath, outpath).then( result => {
        return { entry: "..." } // Etc etc
    } )
}

I prefer len([b for b in boollist if b is True]) (or the generator-expression equivalent), as it's quite self-explanatory. Less 'magical' than the answer proposed by Ignacio Vazquez-Abrams.

Alternatively, you can do this, which still assumes that bool is convertable to int, but makes no assumptions about the value of True: ntrue = sum(boollist) / int(True)

My few cents to previous excellent replies. the site www.sqlite.org works on a sqlite database. Here is the link when the author (Richard Hipp) replies to a similar question.

Try this definitely work.

SELECT p.PersonID AS person_id,
   p.Name, p.SS, 
   f.FearID AS fear_id,
   f.Fear 
   FROM person_fear AS pf 
      LEFT JOIN persons AS p ON pf.PersonID = p.PersonID 
      LEFT JOIN fears AS f ON pf.PersonID = f.FearID 
   WHERE f.FearID = pf.FearID AND p.PersonID = pf.PersonID

Using PowerShell you can minimize from the same file without opening a new instance.

powershell -window minimized -command ""

When you call setBackgoundColor it overwrites/removes any existing background resource, including any borders, corners, padding, etc. What you want to do is change the color of the existing background resource...

View v;
v.getBackground().setColorFilter(Color.parseColor("#00ff00"), PorterDuff.Mode.DARKEN);

Experiment with PorterDuff.Mode.* for different effects.

Open Notepad++, then click Ctrl+ F.

Choose Regular Expression

*Find What: "^" (which represents index of the each line - "PREFIX").

Replace with : "anyText"*

For Suffix on each line: Follow the same steps as above "Replace ^ with $" . That's it.

If you changed awk '{print $1}' to '{ $1=""; print $0}' you will get all processes except for the first as a result. It will start with the field separator (a space generally) but I don't recall killall caring. So:

#! /bin/bash

logfile="/var/oscamlog/oscam1check.log"

case "$(pidof oscam1 | wc -w)" in

0)  echo "oscam1 not running, restarting oscam1:     $(date)" >> $logfile
    /usr/local/bin/oscam1 -b -c /usr/local/etc/oscam1 -t /usr/local/tmp.oscam1 &
    ;;
2)  echo "oscam1 running, all OK:     $(date)" >> $logfile
    ;;
*)  echo "multiple instances of oscam1 running. Stopping & restarting oscam1:     $(date)" >> $logfile
    kill $(pidof oscam1 | awk '{ $1=""; print $0}')
    ;;
esac

It is worth noting that the pidof route seems to work fine for commands that have no spaces, but you would probably want to go back to a ps-based string if you were looking for, say, a python script named myscript that showed up under ps like

root 22415 54.0 0.4 89116 79076 pts/1 S 16:40 0:00 /usr/bin/python /usr/bin/myscript

Just an FYI

JSON.parse() doesn't recognize That data as string. For example {objAskGrant:"Yes",objPass:"asdfasdf",objNameSurname:"asdfasdf adfasdf",objEmail:"[email protected]",objGsm:3241234123,objAdres:"asdfasdf",objTerms:"CheckIsValid"}

Which is like this: JSON.parse({objAskGrant:"Yes",objPass:"asdfasdf",objNameSurname:"asdfasdf adfasdf",objEmail:"[email protected]",objGsm:3241234123,objAdres:"asdfasdf",objTerms:"CheckIsValid"}); That will output SyntaxError: missing " ' " instead of "{" on line...

So correctly wrap all data like this: '{"objAskGrant":"Yes","objPass":"asdfasdf","objNameSurname":"asdfasdf adfasdf","objEmail":"[email protected]","objGsm":3241234123,"objAdres":"asdfasdf","objTerms":"CheckIsValid"}' Which works perfectly well for me.

And not like this: "{"objAskGrant":"Yes","objPass":"asdfasdf","objNameSurname":"asdfasdf adfasdf","objEmail":"[email protected]","objGsm":3241234123,"objAdres":"asdfasdf","objTerms":"CheckIsValid"}" Which give the present error you are experiencing.

As the other comments suggest, you are confined to using pointers. But if it helps, here is one technique to avoid facing directly with pointers.

You can do something like the following:

vector<int*> iarray;
int default_item = 0; // for handling out-of-range exception

int& get_item_as_ref(unsigned int idx) {
   // handling out-of-range exception
   if(idx >= iarray.size()) 
      return default_item;
   return reinterpret_cast<int&>(*iarray[idx]);
}

In the configuration, you can use <compileSourceRoots>.

these are all the configurations available for 3.8.1 version of compiler plugin. Different versions have different configurations which you can find by running your code with -X after the general mvn command. Like

mvn clean install -X
mvn compiler:compile -X

and search with id or goal or plugin name This may help with other plugins too. Eclipse, intelliJ may not show all configurations as suggestions.

Two-stage authentication is not supported with IIS7 Integrated mode. Authentication is now modularized, so rather than IIS performing authentication followed by asp.net performing authentication, it all happens at the same time.

You can either:

1. Change the app domain to be in IIS6 classic mode...
2. Follow this example (old link) of how to fake two-stage authentication with IIS7 integrated mode.
3. Use Helicon Ape and mod_auth to provide basic authentication

I would highly recommend you to go the more tedious route. Especially if your file size is large.

using(var w = new StreamWriter(path))
{
    for( /* your loop */)
    {
        var first = yourFnToGetFirst();
        var second = yourFnToGetSecond();
        var line = string.Format("{0},{1}", first, second);
        w.WriteLine(line);
        w.Flush();
    }
}

File.AppendAllText() opens a new file, writes the content and then closes the file. Opening files is a much resource-heavy operation, than writing data into open stream. Opening\closing a file inside a loop will cause performance drop.

The approach suggested by Johan solves that problem by storing all the output in memory and then writing it once. However (in case of big files) you program will consume a large amount of RAM and even crash with OutOfMemoryException

Another advantage of my solution is that you can implement pausing\resuming by saving current position in input data.

upd. Placed using in the right place

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //hide status bar
    requestWindowFeature( Window.FEATURE_NO_TITLE );
    getWindow().setFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN );


    setContentView(R.layout.activity_main);
}

Swift:

@connor is the right answer, but if you want to add lines in a print statement what you are looking for is \n and/or \r, these are called Escape Sequences or Escaped Characters, this is a link to Apple documentation on the topic..

Example:

print("First line\nSecond Line\rThirdLine...")

Add the all tiles jars like(tiles-jsp,tiles-servlet,tiles-template,tiles-extras.tiles-core ) to your server lib folder and your application build path then it work if you using apache tailes with spring mvc application

Here, Something about abstract class...

1. Abstract class is an incomplete class so we can't instantiate it.
2. If methods are abstract, class must be abstract.
3. In abstract class, we use abstract and concrete method both.
4. It is illegal to define a class abstract and final both.

Real time example--

If you want to make a new car(WagonX) in which all the another car's properties are included like color,size, engine etc.and you want to add some another features like model,baseEngine in your car.Then simply you create a abstract class WagonX where you use all the predefined functionality as abstract and another functionalities are concrete, which is is defined by you.
Another sub class which extend the abstract class WagonX,By default it also access the abstract methods which is instantiated in abstract class.SubClasses also access the concrete methods by creating the subclass's object.
For reusability the code, the developers use abstract class mostly.

abstract class WagonX
{
   public abstract void model();
   public abstract void color();
   public static void baseEngine()
    {
     // your logic here
    }
   public static void size()
   {
   // logic here
   }
}
class Car extends WagonX
{
public void model()
{
// logic here
}
public void color()
{
// logic here
}
}

So you can do this

$('#textarea').attr('enable',false)

try it and give feedback

Since it's a user-facing page always use 404. It's the only code people know usually.

The accepted answer uses the Apache Commons package but this is how I did it using Java's native libraries

Java 11 and up

import java.util.Base64;

public class Base64Encoding {

    public static void main(String[] args) {
        Base64.Encoder enc = Base64.getEncoder();
        Base64.Decoder dec = Base64.getDecoder();
        String str = "77+9x6s=";

        // encode data using BASE64
        String encoded = enc.encodeToString(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data
        String decoded = new String(dec.decode(encoded));
        System.out.println("decoded value is \t" + decoded);
        System.out.println("original value is \t" + str);
    }
}

Java 6 - 10

import java.io.UnsupportedEncodingException;    
import javax.xml.bind.DatatypeConverter;

public class EncodeString64 {
    public static void main(String[] args) throws UnsupportedEncodingException {

        String str = "77+9x6s=";
        // encode data using BASE64
        String encoded = DatatypeConverter.printBase64Binary(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data 
        String decoded = new String(DatatypeConverter.parseBase64Binary(encoded));
        System.out.println("decoded value is \t" + decoded);

        System.out.println("original value is \t" + str);
    }
}

The better way would be to try/catch the encoding/decoding steps but hopefully you get the idea.

I resolved a similar issue by simply restarting Visual Studio with admin rights.

The problem was because it couldn't open one project related to Sharepoint without elevated access.

In your case, since you are only showing 3 columns:

Name    Value       Business
  or
Name    Business    Ecommerce Pro

why not set all 3 to have a width of 33.3%. since only 3 are ever shown at once, the browser should render them all a similar width.

Guava's function Maps.transformValues is what you are looking for, and it works nicely with lambda expressions:

Maps.transformValues(originalMap, val -> ...)

Dragon NaturallySpeaking seems to support MP3 input.

If you want an open source version (I think there are some Asterisk integration projects based on this one).

If you are working with elements of unknown size, and you want to use position: absolute on them or their siblings, you're inevitably going to have to deal with overlap. By setting absolute position you're removing the element from the document flow, but the behaviour you want is that your element should be be pushed around by its siblings so as not to overlap...ie it should flow! You're seeking two totally contradictory things.

You should rethink your layout.

Perhaps what you want is that the .btn element should be absolutely positioned with respect to one of its preceding siblings, rather than against their common parent? In that case, you should set position: relative on the element you'd like to position the button against, and then make the button a child of that element. Now you can use absolute positioning and control overlap.

Keyboard notifications work, but Apple's sample code for that assumes that the scroll view is the root view of the window. This is usually not the case. You have to compensate for tab bars, etc., to get the right offset.

It is easier than it sounds. Here is the code I use in a UITableViewController. It has two instance variables, hiddenRect and keyboardShown.

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification {
    if (keyboardShown)
        return;

    NSDictionary* info = [aNotification userInfo];

    // Get the frame of the keyboard.
    NSValue *centerValue = [info objectForKey:UIKeyboardCenterEndUserInfoKey];
    NSValue *boundsValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
    CGPoint keyboardCenter = [centerValue CGPointValue];
    CGRect keyboardBounds = [boundsValue CGRectValue];
    CGPoint keyboardOrigin = CGPointMake(keyboardCenter.x - keyboardBounds.size.width / 2.0,
                                         keyboardCenter.y - keyboardBounds.size.height / 2.0);
    CGRect keyboardScreenFrame = { keyboardOrigin, keyboardBounds.size };


    // Resize the scroll view.
    UIScrollView *scrollView = (UIScrollView *) self.tableView;
    CGRect viewFrame = scrollView.frame;
    CGRect keyboardFrame = [scrollView.superview convertRect:keyboardScreenFrame fromView:nil];
    hiddenRect = CGRectIntersection(viewFrame, keyboardFrame);

    CGRect remainder, slice;
    CGRectDivide(viewFrame, &slice, &remainder, CGRectGetHeight(hiddenRect), CGRectMaxYEdge);
    scrollView.frame = remainder;

    // Scroll the active text field into view.
    CGRect textFieldRect = [/* selected cell */ frame];
    [scrollView scrollRectToVisible:textFieldRect animated:YES];

    keyboardShown = YES;
}


// Called when the UIKeyboardDidHideNotification is sent
- (void)keyboardWasHidden:(NSNotification*)aNotification
{
    // Reset the height of the scroll view to its original value
    UIScrollView *scrollView = (UIScrollView *) self.tableView;
    CGRect viewFrame = [scrollView frame];
    scrollView.frame = CGRectUnion(viewFrame, hiddenRect);

    keyboardShown = NO;
}

If all you want is the optical effect that the textbox has no blue selection all over its contents, just select no text:

textBox_Log.SelectionStart = 0;
textBox_Log.SelectionLength = 0;
textBox_Log.Select();

After this, when adding content with .Text += "...", no blue selection will be shown.

Note: This answer has been updated for Swift too.

What about to have it on one line?

Extending @Christopher Rogers answer – the accepted one.

[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:[[NSBundle mainBundle] bundleIdentifier]];

and yes, sometime you may need to synchronize it,

[[NSUserDefaults standardUserDefaults] synchronize];

I've created a method to do this,

- (void) clearDefaults {
    [[NSUserDefaults standardUserDefaults] removePersistentDomainForName:[[NSBundle mainBundle] bundleIdentifier]];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

Swift?

With swift its even more easy.

extension UserDefaults {
    class func clean() {
        guard let aValidIdentifier = Bundle.main.bundleIdentifier else { return }
        standard.removePersistentDomain(forName: aValidIdentifier)
        standard.synchronize()
    }
}

And usage:

UserDefaults.clean()

If you know the number of levels in nested arrays you can simply do nested loops. Like so:

//  Scan through outer loop
foreach ($tmpArray as $innerArray) {
    //  Check type
    if (is_array($innerArray)){
        //  Scan through inner loop
        foreach ($innerArray as $value) {
            echo $value;
        }
    }else{
        // one, two, three
        echo $innerArray;
    }
}

if you do not know the depth of array you need to use recursion. See example below:

//  Multi-dementional Source Array
$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(
            7,
            8,
            array("four", 9, 10)
    ))
);

//  Output array
displayArrayRecursively($tmpArray);

/**
 * Recursive function to display members of array with indentation
 *
 * @param array $arr Array to process
 * @param string $indent indentation string
 */
function displayArrayRecursively($arr, $indent='') {
    if ($arr) {
        foreach ($arr as $value) {
            if (is_array($value)) {
                //
                displayArrayRecursively($value, $indent . '--');
            } else {
                //  Output
                echo "$indent $value \n";
            }
        }
    }
}

The code below with display only nested array with values for your specific case (3rd level only)

$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(7, 8, 9))
);

//  Scan through outer loop
foreach ($tmpArray as $inner) {

    //  Check type
    if (is_array($inner)) {
        //  Scan through inner loop
        foreach ($inner[1] as $value) {
           echo "$value \n";
        }
    }
}

I finally figured out the regex to change these all in old Python2 example scripts. Otherwise use 2to3.py.

Try it out on Regexr.com, doesn't work in NP++(?):

find:     (?<=print)( ')(.*)(')
replace: ('$2')

for variables:

(?<=print)( )(.*)(\n)
('$2')\n

for label and variable:

(?<=print)( ')(.*)(',)(.*)(\n)
('$2',$4)\n

Using RxJs, you can declare a Subject in your parent component and pass it as Observable to child component, child component just need to subscribe to this Observable.

Parent-Component

eventsSubject: Subject<void> = new Subject<void>();

emitEventToChild() {
  this.eventsSubject.next();
}

Parent-HTML

<child [events]="eventsSubject.asObservable()"> </child>    

Child-Component

private eventsSubscription: Subscription;

@Input() events: Observable<void>;

ngOnInit(){
  this.eventsSubscription = this.events.subscribe(() => doSomething());
}

ngOnDestroy() {
  this.eventsSubscription.unsubscribe();
}

As mentioned you need to use obj.getTile()

But, in this case I think you are looking to use a Property.

public class Pin
{
    private string title;

    public Pin() { }

    public setTitle(string title) {
        this.title = title;
    }

    public String Title
    {
        get { return title; }
    }
}

This will allow you to use

foreach (Pin obj in ClassListPin.pins)
{
     string t = obj.Title;
}

More detailed information are available in the platform module.

Now, I can't use DateTime?, I am using DBNull.Value for all data types. It works great.

eventCustom.DateTimeEnd = string.IsNullOrWhiteSpace(dateTimeEnd)
  ? DBNull.Value
  : DateTime.Parse(dateTimeEnd);

Without using '%'.

public int lastDigit(int no){
    int n1 = no / 10;
    n1 = no - n1 * 10;
    return n1;
}

The following is one of the simplest ways to do it, use the following code:

Dependencies

dependencies {
    ...
    compile 'de.hdodenhof:circleimageview:2.1.0'      // use this or use the latest compile version. In case u get bug.
}

XML Code

<de.hdodenhof.circleimageview.CircleImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/profile_image"
    android:layout_width="96dp"             //  here u can adjust the width 
    android:layout_height="96dp"            //  here u can adjust the height 
    android:src="@drawable/profile"         //  here u can change the image 
    app:civ_border_width="2dp"              //  here u can adjust the border of the circle.  
    app:civ_border_color="#FF000000"/>      //  here u can adjust the border color

Well try ini_set('memory_limit', '256M');

134217728 bytes = 128 MB

Or rewrite the code to consume less memory.

system

The system method calls a system program. You have to provide the command as a string argument to this method. For example:

>> system("date")
Wed Sep 4 22:03:44 CEST 2013
=> true

The invoked program will use the current STDIN, STDOUT and STDERR objects of your Ruby program. In fact, the actual return value is either true, false or nil. In the example the date was printed through the IO object of STDIN. The method will return true if the process exited with a zero status, false if the process exited with a non-zero status and nil if the execution failed.

As of Ruby 2.6, passing exception: true will raise an exception instead of returning false or nil:

>> system('invalid')
=> nil

>> system('invalid', exception: true)
Traceback (most recent call last):
...
Errno::ENOENT (No such file or directory - invalid)

Another side effect is that the global variable $? is set to a Process::Status object. This object will contain information about the call itself, including the process identifier (PID) of the invoked process and the exit status.

>> system("date")
Wed Sep 4 22:11:02 CEST 2013
=> true
>> $?
=> #<Process::Status: pid 15470 exit 0>

Backticks

Backticks (``) call a system program and return its output. As opposed to the first approach, the command is not provided through a string, but by putting it inside a backticks pair.

>> `date`
=> Wed Sep 4 22:22:51 CEST 2013   

The global variable $? is set through the backticks, too. With backticks you can also make use string interpolation.

%x()

Using %x is an alternative to the backticks style. It will return the output, too. Like its relatives %w and %q (among others), any delimiter will suffice as long as bracket-style delimiters match. This means %x(date), %x{date} and %x-date- are all synonyms. Like backticks %x can make use of string interpolation.

exec

By using Kernel#exec the current process (your Ruby script) is replaced with the process invoked through exec. The method can take a string as argument. In this case the string will be subject to shell expansion. When using more than one argument, then the first one is used to execute a program and the following are provided as arguments to the program to be invoked.

Open3.popen3

Sometimes the required information is written to standard input or standard error and you need to get control over those as well. Here Open3.popen3 comes in handy:

require 'open3'

Open3.popen3("curl http://example.com") do |stdin, stdout, stderr, thread|
   pid = thread.pid
   puts stdout.read.chomp
end

Simple like that:

date("Y-m-d", strtotime("-1 day"));

date("Y-m-d", strtotime("-1 months"))

You can use android:stopWithTask="false"in manifest as bellow, This means even if user kills app by removing it from tasklist, your service won't stop.

 <service android:name=".service.StickyService"
                  android:stopWithTask="false"/>

Dependencies.

var fs = require('fs');
var path = require('path');

Definition.

// String -> [String]
function fileList(dir) {
  return fs.readdirSync(dir).reduce(function(list, file) {
    var name = path.join(dir, file);
    var isDir = fs.statSync(name).isDirectory();
    return list.concat(isDir ? fileList(name) : [name]);
  }, []);
}

Usage.

var DIR = '/usr/local/bin';

// 1. List all files in DIR
fileList(DIR);
// => ['/usr/local/bin/babel', '/usr/local/bin/bower', ...]

// 2. List all file names in DIR
fileList(DIR).map((file) => file.split(path.sep).slice(-1)[0]);
// => ['babel', 'bower', ...]

Please note that fileList is way too optimistic. For anything serious, add some error handling.

begin   
   dbms_output.put_line( 'hello' ||chr(13) || chr(10) || 'world' );
end;

I've created a new class to handle binding RadioButtons and CheckBoxes to enums. It works for flagged enums (with multiple checkbox selections) and non-flagged enums for single-selection checkboxes or radio buttons. It also requires no ValueConverters at all.

This might look more complicated at first, however, once you copy this class into your project, it's done. It's generic so it can easily be reused for any enum.

public class EnumSelection<T> : INotifyPropertyChanged where T : struct, IComparable, IFormattable, IConvertible
{
  private T value; // stored value of the Enum
  private bool isFlagged; // Enum uses flags?
  private bool canDeselect; // Can be deselected? (Radio buttons cannot deselect, checkboxes can)
  private T blankValue; // what is considered the "blank" value if it can be deselected?

  public EnumSelection(T value) : this(value, false, default(T)) { }
  public EnumSelection(T value, bool canDeselect) : this(value, canDeselect, default(T)) { }
  public EnumSelection(T value, T blankValue) : this(value, true, blankValue) { }
  public EnumSelection(T value, bool canDeselect, T blankValue)
  {
    if (!typeof(T).IsEnum) throw new ArgumentException($"{nameof(T)} must be an enum type"); // I really wish there was a way to constrain generic types to enums...
    isFlagged = typeof(T).IsDefined(typeof(FlagsAttribute), false);

    this.value = value;
    this.canDeselect = canDeselect;
    this.blankValue = blankValue;
  }

  public T Value
  {
    get { return value; }
    set 
    {
      if (this.value.Equals(value)) return;
      this.value = value;
      OnPropertyChanged();
      OnPropertyChanged("Item[]"); // Notify that the indexer property has changed
    }
  }

  [IndexerName("Item")]
  public bool this[T key]
  {
    get
    {
      int iKey = (int)(object)key;
      return isFlagged ? ((int)(object)value & iKey) == iKey : value.Equals(key);
    }
    set
    {
      if (isFlagged)
      {
        int iValue = (int)(object)this.value;
        int iKey = (int)(object)key;

        if (((iValue & iKey) == iKey) == value) return;

        if (value)
          Value = (T)(object)(iValue | iKey);
        else
          Value = (T)(object)(iValue & ~iKey);
      }
      else
      {
        if (this.value.Equals(key) == value) return;
        if (!value && !canDeselect) return;

        Value = value ? key : blankValue;
      }
    }
  }

  public event PropertyChangedEventHandler PropertyChanged;

  private void OnPropertyChanged([CallerMemberName] string propertyName = "")
  {
    PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
  }
}

And for how to use it, let's say you have an enum for running a task manually or automatically, and can be scheduled for any days of the week, and some optional options...

public enum StartTask
{
  Manual,
  Automatic
}

[Flags()]
public enum DayOfWeek
{
  Sunday = 1 << 0,
  Monday = 1 << 1,
  Tuesday = 1 << 2,
  Wednesday = 1 << 3,
  Thursday = 1 << 4,
  Friday = 1 << 5,
  Saturday = 1 << 6
}

public enum AdditionalOptions
{
  None = 0,
  OptionA,
  OptionB
}

Now, here's how easy it is to use this class:

public class MyViewModel : ViewModelBase
{
  public MyViewModel()
  {
    StartUp = new EnumSelection<StartTask>(StartTask.Manual);
    Days = new EnumSelection<DayOfWeek>(default(DayOfWeek));
    Options = new EnumSelection<AdditionalOptions>(AdditionalOptions.None, true, AdditionalOptions.None);
  }

  public EnumSelection<StartTask> StartUp { get; private set; }
  public EnumSelection<DayOfWeek> Days { get; private set; }
  public EnumSelection<AdditionalOptions> Options { get; private set; }
}

And here's how easy it is to bind checkboxes and radio buttons with this class:

<StackPanel Orientation="Vertical">
  <StackPanel Orientation="Horizontal">
    <!-- Using RadioButtons for exactly 1 selection behavior -->
    <RadioButton IsChecked="{Binding StartUp[Manual]}">Manual</RadioButton>
    <RadioButton IsChecked="{Binding StartUp[Automatic]}">Automatic</RadioButton>
  </StackPanel>
  <StackPanel Orientation="Horizontal">
    <!-- Using CheckBoxes for 0 or Many selection behavior -->
    <CheckBox IsChecked="{Binding Days[Sunday]}">Sunday</CheckBox>
    <CheckBox IsChecked="{Binding Days[Monday]}">Monday</CheckBox>
    <CheckBox IsChecked="{Binding Days[Tuesday]}">Tuesday</CheckBox>
    <CheckBox IsChecked="{Binding Days[Wednesday]}">Wednesday</CheckBox>
    <CheckBox IsChecked="{Binding Days[Thursday]}">Thursday</CheckBox>
    <CheckBox IsChecked="{Binding Days[Friday]}">Friday</CheckBox>
    <CheckBox IsChecked="{Binding Days[Saturday]}">Saturday</CheckBox>
  </StackPanel>
  <StackPanel Orientation="Horizontal">
    <!-- Using CheckBoxes for 0 or 1 selection behavior -->
    <CheckBox IsChecked="{Binding Options[OptionA]}">Option A</CheckBox>
    <CheckBox IsChecked="{Binding Options[OptionB]}">Option B</CheckBox>
  </StackPanel>
</StackPanel>

1. When the UI loads, the "Manual" radio button will be selected and you can alter your selection between "Manual" or "Automatic" but either one of them must always be selected.
2. Every day of the week will be unchecked, but any number of them can be checked or unchecked.
3. "Option A" and "Option B" will both initially be unchecked. You can check one or the other, checking one will uncheck the other (similar to RadioButtons), but now you can also uncheck both of them (which you cannot do with WPF's RadioButton, which is why CheckBox is being used here)

In my conclusion we have this:

Soap client side:

use only Suds-jurko (updated 2016) suds is well maintained and updated.

UPDATE 06/2017: suds-jurko library is not updated and apparently abandoned,

I tested zeep library but got limitations around tokens, by now just support UsernameToken, i report a bug to create timestamp token and author update the code to fix it.

Zeep start good and has good documentation , so i recently migrated my code from suds to zeep and works fine.

Soap server side:

We have TGWS, soaplib (pysimplesoap not tested) IMHO use and help soaplib must be the choice.

Best regards,

By default it will be hidden in your home directory. Type ls -a ~ to view that.

In an ASP.NET application, I think it goes to the Output or Console window which is visible during debugging.

Adding table alias in front Set field causes this problem in my case.

Right Update Table1 Set SomeField = t2.SomeFieldValue From Table1 t1 Inner Join Table2 as t2 On t1.ID = t2.ID

Wrong Update Table1 Set t1.SomeField = t2.SomeFieldValue From Table1 t1 Inner Join Table2 as t2 On t1.ID = t2.ID

An easy way that is compatible pretty much everywhere is to set font-size: 0 on the container, provided you don't have any descendent text nodes you need to style (though it is trivial to override this where needed).

.nospace {
   font-size: 0;
}

jsFiddle.

You could also change from the default display: inline into block or inline-block. Be sure to use the workarounds required for <= IE7 (and possibly ancient Firefoxes) for inline-block to work.

I had to deal with this for my responsive website. I have many different backgrounds for the same elements to deal with different screen widths. My solution is very simple, keep all your images scoped to a css selector, like "zoinked".

The logic:

If user scrolls, then load in styles with background images associated with them. Done!

Here's what I wrote in a library I call "zoinked" I dunno why. It just happened ok?

(function(window, document, undefined) {   var Z = function() {
    this.hasScrolled = false;

    if (window.addEventListener) {
      window.addEventListener("scroll", this, false);
    } else {
      this.load();
    }   };
     Z.prototype.handleEvent = function(e) {
    if ($(window).scrollTop() > 2) {
      this.hasScrolled = true;
      window.removeEventListener("scroll", this);
      this.load();
    }   };
     Z.prototype.load = function() {
    $(document.body).addClass("zoinked");   };
     window.Zoink = Z; 
})(window, document);

For the CSS I'll have all my styles like this:

.zoinked #graphic {background-image: url(large.jpg);}

@media(max-width: 480px) {.zoinked #graphic {background-image: url(small.jpg);}}

My technique with this is to load all the images after the top ones as soon as the user starts to scroll. If you wanted more control you could make the "zoinking" more intelligent.

This following solution is the most compact I could come up with that is O(n).

public static IEnumerable<T[]> Chunk<T>(IEnumerable<T> source, int chunksize)
{
    var list = source as IList<T> ?? source.ToList();
    for (int start = 0; start < list.Count; start += chunksize)
    {
        T[] chunk = new T[Math.Min(chunksize, list.Count - start)];
        for (int i = 0; i < chunk.Length; i++)
            chunk[i] = list[start + i];

        yield return chunk;
    }
}

Express 4.x Updated Answer

Session handling is no longer built into Express. This answer refers to the standard session module: https://github.com/expressjs/session

To clear the session data, simply use:

req.session.destroy();

The documentation is a bit useless on this. It says:

Destroys the session, removing req.session, will be re-generated next request. req.session.destroy(function(err) { // cannot access session here })

This does not mean that the current session will be re-loaded on the next request. It means that a clean empty session will be created in your session store on next request. (Presumably the session ID isn't changing, but I have not tested that.)

For newer versions of Ubuntu that have PHP 7.0 you can get the php-mysql package:

sudo apt-get install php-mysql

Then restart your server:

sudo service apache2 restart

Use different format or pattern to get the information from the date

var myDate = new Date("2015-06-17 14:24:36");_x000D_
console.log(moment(myDate).format("YYYY-MM-DD HH:mm:ss"));_x000D_
console.log("Date: "+moment(myDate).format("YYYY-MM-DD"));_x000D_
console.log("Year: "+moment(myDate).format("YYYY"));_x000D_
console.log("Month: "+moment(myDate).format("MM"));_x000D_
console.log("Month: "+moment(myDate).format("MMMM"));_x000D_
console.log("Day: "+moment(myDate).format("DD"));_x000D_
console.log("Day: "+moment(myDate).format("dddd"));_x000D_
console.log("Time: "+moment(myDate).format("HH:mm")); // Time in24 hour format_x000D_
console.log("Time: "+moment(myDate).format("hh:mm A"));

<script src="https://momentjs.com/downloads/moment.js"></script>

For more info: https://momentjs.com/docs/#/parsing/string-format/

COLUMN() and ROW() won't work this way because they are applied to the cell that is calling them. In conditional formatting, you will have to be explicit instead of implicit.

For instance, if you want to use this conditional formating on a range begining on cell A1, you can try:

`COLUMN(A1)` and `ROW(A1)`

Excel will automatically adapt the conditional formating to the current cell.

The easiest way was to (prior to Java 8) use,

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

But SimpleDateFormat is not thread-safe. Neither java.util.Date. This will lead to leading to potential concurrency issues for users. And there are many problems in those existing designs. To overcome these now in Java 8 we have a separate package called java.time. This Java SE 8 Date and Time document has a good overview about it.

So in Java 8 something like below will do the trick (to format the current date/time),

LocalDateTime.now()
   .format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

And one thing to note is it was developed with the help of the popular third party library joda-time,

The project has been led jointly by the author of Joda-Time (Stephen Colebourne) and Oracle, under JSR 310, and will appear in the new Java SE 8 package java.time.

But now the joda-time is becoming deprecated and asked the users to migrate to new java.time.

Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project

Anyway having said that,

If you have a Calendar instance you can use below to convert it to the new java.time,

    Calendar calendar = Calendar.getInstance();
    long longValue = calendar.getTimeInMillis();         

    LocalDateTime date =
            LocalDateTime.ofInstant(Instant.ofEpochMilli(longValue), ZoneId.systemDefault());
    String formattedString = date.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

    System.out.println(date.toString()); // 2018-03-06T15:56:53.634
    System.out.println(formattedString); // 2018-03-06 15:56:53.634

If you had a Date object,

    Date date = new Date();
    long longValue2 = date.getTime();

    LocalDateTime dateTime =
            LocalDateTime.ofInstant(Instant.ofEpochMilli(longValue2), ZoneId.systemDefault());
    String formattedString = dateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

    System.out.println(dateTime.toString()); // 2018-03-06T15:59:30.278
    System.out.println(formattedString);     // 2018-03-06 15:59:30.278

If you just had the epoch milliseconds,

LocalDateTime date =
        LocalDateTime.ofInstant(Instant.ofEpochMilli(epochLongValue), ZoneId.systemDefault());
