1. Add an exit handler that closes all the bars.
2. __del__() gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.
3. If __init__() raises an exception then the object is assumed to be incomplete and __del__() won't be invoked.

if you are uploading binary file such as csv, use below format to upload file

curl -X POST \

I use the following in my ~/.vimrc

nnoremap <Leader><space> :noh<Enter>

This makes it very easy and quick to clear the current highlighted search. My leader key is mapped to \ so this makes the action very easy to perform with my right pinky finger and thumb.

Doesn't answer the question but this is the top google result.

If anybody comes here and wants do do it for Spring 4 (as it happened to me), you can use the annotation

@JsonInclude(Include.NON_NULL)

on the returning class.

Using the default works, but so does:

urls[url] = urls.get(url, 0) + 1

using .get, you can get a default return if it doesn't exist. By default it's None, but in the case I sent you, it would be 0.

I struggled with this from behind a proxy so I thought I should post what I did. Below one is worked for me.

-> "export HTTPS_PROXY=(yourproxy)"

If you want to keep the multi dimensional array, one should nest the array brackets. see example below where one is added to every element.

>>> a = [[1, 2], [3, 4]]

>>> [[col +1 for col in row] for row in a]
[[2, 3], [4, 5]]

>>> [col +1 for row in a for col in row]
[2, 3, 4, 5]

In Vim you can do one of the following:

• Comment all lines: :%s/^/#
• Comment lines 10 - 15: :10,15s/^/#
• Comment line 10 to current line: :10,.s/^/#
• Comment line 10 to end: :10,$s/^/#

or using visual block:

1. Select a multiple-line column after entering visual block via Ctrl+v.
2. Press r followed by # to comment out the multiple-line block replacing the selection, or Shift+i#Esc to insert comment characters before the selection.

Leaving my specific solution of this for prosperity, as it's a tricky version of this problem:

Type 'System.Linq.Enumerable+WhereSelectArrayIterator[T...] was not marked as serializable

Due to a class with an attribute IEnumerable<int> eg:

[Serializable]
class MySessionData{
    public int ID;
    public IEnumerable<int> RelatedIDs; //This can be an issue
}

Originally the problem instance of MySessionData was set from a non-serializable list:

MySessionData instance = new MySessionData(){ 
    ID = 123,
    RelatedIDs = nonSerizableList.Select<int>(item => item.ID)
};

The cause here is the concrete class that the Select<int>(...) returns, has type data that's not serializable, and you need to copy the id's to a fresh List<int> to resolve it.

RelatedIDs = nonSerizableList.Select<int>(item => item.ID).ToList();

jus do this import { shallow, mount } from "enzyme";

const store = mockStore({
  startup: { complete: false }
});

describe("==== Testing App ======", () => {
  const setUpFn = props => {
    return mount(
      <Provider store={store}>
        <App />
      </Provider>
    );
  };

  let wrapper;
  beforeEach(() => {
    wrapper = setUpFn();
  });

There are already so many good answers on this thread! I am going to post this to help anybody trying to do this automatically! To automatically remove unused imports for the whole project this article was really helpful to me.

In the article the author explains it like this:

Make a stand alone tslint file that has the following in it:

{
  "extends": ["tslint-etc"],
  "rules": {
    "no-unused-declaration": true
  }
}

Then run the following command to fix the imports:

 tslint --config tslint-imports.json --fix --project .

Consider fixing any other errors it throws. (I did)

Then check the project works by building it:

ng build

or

ng build name_of_project --configuration=production 

End: If it builds correctly, you have successfully removed imports automatically!

NOTE: This only removes unnecessary imports. It does not provide the other features that VS Code does when using one of the commands previously mentioned.

Look before you leap (LBYL):

if idx < len(array):
    array[idx]
else:
    # handle this

Easier to ask forgiveness than permission (EAFP):

try:
    array[idx]
except IndexError:
    # handle this

In Python, EAFP seems to be the popular and preferred style. It is generally more reliable, and avoids an entire class of bugs (time of check vs. time of use). All other things being equal, the try/except version is recommended - don't see it as a "last resort".

This excerpt is from the official docs linked above, endorsing using try/except for flow control:

This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements.

For everyone who is stuck with .NET 2.0, like me, try the following way (applicable to the example in the OP):

ConfigItemList.ConvertAll<string>(delegate (ConfigItemType ci) 
{ 
   return ci.Name; 
}).ToArray();

where ConfigItemList is your list variable.

For this label:

<asp:label id="myLabel" runat="server" />

In the code behind use (C#):

myLabel.Text = "my text"; 

Update (following updated question):

You do not need to use FindControl - that whole line is superfluous:

  Label myLabel = this.FindControl("myLabel") as Label;
  myLabel.Text = "my text";

Should be just:

  myLabel.Text = "my text";

The Visual Studio designer should create a file with all the server side controls already added properly to the class (in a RankPage.aspx.designer.cs file, by default).

You are talking about a RankPage.cs file - the way Visual Studio would have named it is RankPage.aspx.cs. How are you linking these files together?

There's a lot of answers here, but no-one seems to have really explained why it is that rand() always generates the same sequence given the same seed - or even what the seed is really doing. So here goes.

The rand() function maintains an internal state. Conceptually, you could think of this as a global variable of some type called rand_state. Each time you call rand(), it does two things. It uses the existing state to calculate a new state, and it uses the new state to calculate a number to return to you:

state_t rand_state = INITIAL_STATE;

state_t calculate_next_state(state_t s);
int calculate_return_value(state_t s);

int rand(void)
{
    rand_state = calculate_next_state(rand_state);
    return calculate_return_value(rand_state);
}

Now you can see that each time you call rand(), it's going to make rand_state move one step along a pre-determined path. The random values you see are just based on where you are along that path, so they're going to follow a pre-determined sequence too.

Now here's where srand() comes in. It lets you jump to a different point on the path:

state_t generate_random_state(unsigned int seed);

void srand(unsigned int seed)
{
    rand_state = generate_random_state(seed);
}

The exact details of state_t, calculate_next_state(), calculate_return_value() and generate_random_state() can vary from platform to platform, but they're usually quite simple.

You can see from this that every time your program starts, rand_state is going to start off at INITIAL_STATE (which is equivalent to generate_random_state(1)) - which is why you always get the same sequence if you don't use srand().

Another Variation can be... Be sure to close the file afterwards

import sys
file = open('output.txt', 'a')
sys.stdout = file

print("Hello stackoverflow!") 
print("I have a question.")

file.close()

If you want to import your existing mercurial repository into a 'GitHub' repository, you can now simply use GitHub Importer available here [Login required]. No more messing around with fast-export etc. (although its a very good tool)

You will get all your commits, branches and tags intact. One more cool thing is that you can change the author's email-id as well. Check out below screenshots:

Is better to use a validation to support versions pre Android N, example:

  if (Build.VERSION.SDK_INT >=  Build.VERSION_CODES.N) {
     imageUri = Uri.parse(filepath);
  } else{
     imageUri = Uri.fromFile(new File(filepath));
  }

  if (Build.VERSION.SDK_INT >=  Build.VERSION_CODES.N) {
     ImageView.setImageURI(Uri.parse(new File("/sdcard/cats.jpg").toString()));         
  } else{
     ImageView.setImageURI(Uri.fromFile(new File("/sdcard/cats.jpg")));
  }

public void start(Stage mainStage) throws Exception {

    Scene scene = new Scene(new Region());
    mainStage.setWidth(640);
    mainStage.setHeight(480);
    mainStage.setScene(scene);

    //this makes all stages close and the app exit when the main stage is closed
    mainStage.setOnCloseRequest(e -> Platform.exit());

    //add real stuff to the scene...
    //open secondary stages... etc...
}

In order to get the formula to work place the cursor inside the formula and press ctr+shift+enter and then it will work!

The UDF approach is my preference compared to brittle substr values.

The SQLite equivalent of anything this robust is a tangled weave of substr and instr calls that you should avoid.

• name attribute points to the column containing the asociation, i.e. column name of the foreign key
• referencedColumnName attribute points to the related column in asociated/referenced entity, i.e. column name of the primary key

You are not required to fill the referencedColumnName if the referenced entity has single column as PK, because there is no doubt what column it references (i.e. the Address single column ID).

@ManyToOne
@JoinColumn(name="ADDR_ID")
public Address getAddress() { return address; }

However if the referenced entity has PK that spans multiple columns the order in which you specify @JoinColumn annotations has significance. It might work without the referencedColumnName specified, but that is just by luck. So you should map it like this:

@ManyToOne
@JoinColumns({
    @JoinColumn(name="ADDR_ID", referencedColumnName="ID"),
    @JoinColumn(name="ADDR_ZIP", referencedColumnName="ZIP")
})
public Address getAddress() { return address; }

or in case of ManyToMany:

@ManyToMany
@JoinTable(
    name="CUST_ADDR",
    joinColumns=
        @JoinColumn(name="CUST_ID"),
    inverseJoinColumns={
        @JoinColumn(name="ADDR_ID", referencedColumnName="ID"),
        @JoinColumn(name="ADDR_ZIP", referencedColumnName="ZIP")
    }
)

Real life example

Two queries generated by Hibernate of the same join table mapping, both without referenced column specified. Only the order of @JoinColumn annotations were changed.

/* load collection Client.emails */ 
select 
emails0_.id_client as id1_18_1_,
emails0_.rev as rev18_1_,
emails0_.id_email as id3_1_,
email1_.id_email as id1_6_0_

from client_email emails0_ 
inner join email email1_ on emails0_.id_email=email1_.id_email 

where emails0_.id_client='2' and 
emails0_.rev='18'

/* load collection Client.emails */ 
select
emails0_.rev as rev18_1_,
emails0_.id_client as id2_18_1_,
emails0_.id_email as id3_1_, 
email1_.id_email as id1_6_0_

from client_email emails0_ 
inner join email email1_ on emails0_.id_email=email1_.id_email 

where emails0_.rev='2' and 
emails0_.id_client='18'

We are querying a join table to get client's emails. The {2, 18} is composite ID of Client. The order of column names is determined by your order of @JoinColumn annotations. The order of both integers is always the same, probably sorted by hibernate and that's why proper alignment with join table columns is required and we can't or should rely on mapping order.

The interesting thing is the order of the integers does not match the order in which they are mapped in the entity - in that case I would expect {18, 2}. So it seems the Hibernate is sorting the column names before it use them in query. If this is true and you would order your @JoinColumn in the same way you would not need referencedColumnName, but I say this only for illustration.

Properly filled referencedColumnName attributes result in exactly same query without the ambiguity, in my case the second query (rev = 2, id_client = 18).

Swift 3.0

    let image = UIImage(named:"NoConnection")!

 warningButton = UIButton(type: .system)        
    warningButton.setImage(image, for: .normal)
    warningButton.tintColor = UIColor.lightText
    warningButton.frame = CGRect(origin: CGPoint(x:-100,y:0), size: CGSize(width: 59, height: 56))

    self.addSubview(warningButton)

Since Git 2.14 (Q3 2017), you don't have to go into each submodule to do a git reset (as in git submodule foreach git reset --hard)

That is because git reset itself knows now how to recursively go into submodules.

See commit 35b96d1 (21 Apr 2017), and commit f2d4899, commit 823bab0, commit cd279e2 (18 Apr 2017) by Stefan Beller (stefanbeller).
^{(Merged by Junio C Hamano -- gitster -- in commit 5f074ca, 29 May 2017)}

builtin/reset: add --recurse-submodules switch

git-reset is yet another working tree manipulator, which should be taught about submodules.

When a user uses git-reset and requests to recurse into submodules, this will reset the submodules to the object name as recorded in the superproject, detaching the HEADs.

Warning: the difference between:

• git reset --hard --recurse-submodule and
• git submodule foreach git reset --hard

is that the former will also reset your main parent repo working tree, as the latter would only reset the submodules working tree.
So use with caution.

Out of the box, Visual Studio can compile, run and debug programs.

Out of the box, Visual Studio Code can do practically nothing but open and edit text files. It can be extended to compile, run, and debug, but you will need to install other software. It's a PITA.

If you're looking for a Notepad replacement, Visual Studio Code is your man.

If you want to develop and debug code without fiddling for days with settings and installing stuff, then Visual Studio is your man.

I had this issue, this is how i have solved it. The problem mostly is that your Angular version is not supporting your Node.js version for the build. So the best solution is to upgrade your Node.js to the most current stable one.

For a clean upgrade of Node.js, i advise using n. if you are using Mac.

npm install -g n
npm cache clean -f
sudo n stable
npm update -g

and now check that you are updated:

node -v
npm -v

For more details, check this link: here

First of all it is unclear what type name has. If it has the type std::string then instead of

string nametext;
nametext = "Your name is" << name;

you should write

std::string nametext = "Your name is " + name;

where operator + serves to concatenate strings.

If name is a character array then you may not use operator + for two character arrays (the string literal is also a character array), because character arrays in expressions are implicitly converted to pointers by the compiler. In this case you could write

std::string nametext( "Your name is " );
nametext.append( name );

or

std::string nametext( "Your name is " );
nametext += name;

Given an instance of the struct, you set the values.

    student thisStudent;
    Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");
    thisStudent.s_id = int.Parse(Console.ReadLine());
    thisStudent.s_name = Console.ReadLine();
    thisStudent.c_name = Console.ReadLine();
    thisStudent.s_dob = Console.ReadLine();

Note this code is incredibly fragile, since we aren't checking the input from the user at all. And you aren't clear to the user that you expect each data point to be entered on a separate line.

You may also use the handy replace_na function: https://tidyr.tidyverse.org/reference/replace_na.html

using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process.Start("C:\\");
    }
}

If your application needs cmd arguments, use something like this:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        LaunchCommandLineApp();
    }

    /// <summary>
    /// Launch the application with some options set.
    /// </summary>
    static void LaunchCommandLineApp()
    {
        // For the example
        const string ex1 = "C:\\";
        const string ex2 = "C:\\Dir";

        // Use ProcessStartInfo class
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "dcm2jpg.exe";
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

        try
        {
            // Start the process with the info we specified.
            // Call WaitForExit and then the using statement will close.
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
            }
        }
        catch
        {
             // Log error.
        }
    }
}

Generics can be defined using Wrapper classes only. If you don't want to define using Wrapper types, you may use the Raw definition as below

@SuppressWarnings("rawtypes")
public HashMap buildMap(String letters)
{
    HashMap checkSum = new HashMap();

    for ( int i = 0; i < letters.length(); ++i )
    {
       checkSum.put(letters.charAt(i), primes[i]);
    }
    return checkSum;
}

Or define the HashMap using wrapper types, and store the primitive types. The primitive values will be promoted to their wrapper types.

public HashMap<Character, Integer> buildMap(String letters)
{
  HashMap<Character, Integer> checkSum = new HashMap<Character, Integer>();

  for ( int i = 0; i < letters.length(); ++i )
  {
    checkSum.put(letters.charAt(i), primes[i]);
  }
  return checkSum;
}

you can try these:

document.getElementById("RootNode").onclick = function(){/*do something*/};

or

$('#RootNode').click(function(){/*do something*/});

or

$(document).on("click", "#RootNode", function(){/*do something*/});

There is a point for the first two method which is, it matters where in your page DOM, you should put them, the whole DOM should be loaded, to be able to find the, which is usually it gets solved if you wrap them in a window.onload or DOMReady event, like:

//in Vanilla JavaScript
window.addEventListener("load", function(){
     document.getElementById("RootNode").onclick = function(){/*do something*/};
});
//for jQuery
$(document).ready(function(){
    $('#RootNode').click(function(){/*do something*/});
});

I don't understand what the meaning of ordering with the same column ASC and DESC in the same ORDER BY, but this how you can do it: naam DESC, naam ASC like so:

ORDER BY `product_category_id` DESC,`naam` DESC, `naam` ASC

I actually prefer to use the html button form element and make it runat=server. The button element can hold other elements inside it. You can even add formatting inside it with span's or strong's. Here is an example:

<button id="BtnSave" runat="server"><img src="Images/save.png" />Save</button>

You didn't select post_id in the subquery. You have to select it in the subquery like this:

SELECT wp_woocommerce_order_items.order_id As No_Commande
FROM  wp_woocommerce_order_items
LEFT JOIN 
    (
        SELECT meta_value As Prenom, post_id  -- <----- this
        FROM wp_postmeta
        WHERE meta_key = '_shipping_first_name'
    ) AS a
ON wp_woocommerce_order_items.order_id = a.post_id
WHERE  wp_woocommerce_order_items.order_id =2198 

I have this sample Java Code:

import java.io.*;
import java.net.*;
import java.nio.charset.StandardCharsets;

public class TestClass {
    public static void main(String[] args) throws IOException {
        ServerSocket socket = new ServerSocket(8081);
        Socket accept = socket.accept();
        InputStream inputStream = accept.getInputStream();

        InputStreamReader inputStreamReader = new InputStreamReader(inputStream, StandardCharsets.UTF_8);
        char readChar;
        while ((readChar = (char) inputStreamReader.read()) != -1) {
            System.out.print(readChar);
        }

        inputStream.close();
        accept.close();

</body>
</html>

and finally the file I will be using for testing purposes, named a.dat has the following content:

0x39 0x69 0x65

if you interpret the bytes above as ASCII or UTF-8 characters, they will actually will be representing:

9ie

So let 's run our Java Code, open up test.html in our favorite browser, upload a.dat and submit the form and see what our server receives:

Well I am not surprised to see the characters 9ie because we told Java to print them treating them as UTF-8 characters. You may as well choose to read them as raw bytes..

here is my code:

Use below code :

TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();

In AndroidManifest.xml, give the following permission:

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

But remember, this code does not always work, since Cell phone number is dependent on the SIM Card and the Network operator / Cell phone carrier.

Also, try checking in Phone--> Settings --> About --> Phone Identity, If you are able to view the Number there, the probability of getting the phone number from above code is higher. If you are not able to view the phone number in the settings, then you won't be able to get via this code!

Suggested Workaround:

1. Get the user's phone number as manual input from the user.
2. Send a code to the user's mobile number via SMS.
3. Ask user to enter the code to confirm the phone number.
4. Save the number in sharedpreference.

Do the above 4 steps as one time activity during the app's first launch. Later on, whenever phone number is required, use the value available in shared preference.

I know this is a little off the OPs original request but I came across this while looking for a way to use Invoke-WebRequest against a site requiring basic authentication.

The difference is, I did not want to record the password in the script. Instead, I wanted to prompt the script runner for credentials for the site.

Here's how I handled it

$creds = Get-Credential

$basicCreds = [pscredential]::new($Creds.UserName,$Creds.Password)

Invoke-WebRequest -Uri $URL -Credential $basicCreds

The result is the script runner is prompted with a login dialog for the U/P then, Invoke-WebRequest is able to access the site with those credentials. This works because $Creds.Password is already an encrypted string.

I hope this helps someone looking for a similar solution to the above question but without saving the username or PW in the script

The class declaration goes into the header file. It is important that you add the #ifndef include guards, or if you are on a MS platform you also can use #pragma once. Also I have omitted the private, by default C++ class members are private.

// A2DD.h
#ifndef A2DD_H
#define A2DD_H

class A2DD
{
  int gx;
  int gy;

public:
  A2DD(int x,int y);
  int getSum();

};

#endif

and the implementation goes in the CPP file:

// A2DD.cpp
#include "A2DD.h"

A2DD::A2DD(int x,int y)
{
  gx = x;
  gy = y;
}

int A2DD::getSum()
{
  return gx + gy;
}

You can use this library in Swift for SQLite https://github.com/pmurphyjam/SQLiteDemo

SQLiteDemo

SQLite Demo using Swift with SQLDataAccess class written in Swift

Adding to Your Project

You only need three files to add to your project * SQLDataAccess.swift * DataConstants.swift * Bridging-Header.h Bridging-Header must be set in your Xcode's project 'Objective-C Bridging Header' under 'Swift Compiler - General'

Examples for Use

Just follow the code in ViewController.swift to see how to write simple SQL with SQLDataAccess.swift First you need to open the SQLite Database your dealing with

    let db = SQLDataAccess.shared
    db.setDBName(name:"SQLite.db")
    let opened = db.openConnection(copyFile:true)

If openConnection succeeded, now you can do a simple insert into Table AppInfo

    //Insert into Table AppInfo
    let status = db.executeStatement("insert into AppInfo (name,value,descrip,date) values(?,?,?,?)",
    ”SQLiteDemo","1.0.2","unencrypted",Date())
    if(status)
    {
        //Read Table AppInfo into an Array of Dictionaries
        let results = db.getRecordsForQuery("select * from AppInfo ")
        NSLog("Results = \(results)")
    }

See how simple that was!

The first term in db.executeStatement is your SQL as String, all the terms that follow are a variadic argument list of type Any, and are your parameters in an Array. All these terms are separated by commas in your list of SQL arguments. You can enter Strings, Integers, Date’s, and Blobs right after the sequel statement since all of these terms are considered to be parameters for the sequel. The variadic argument array just makes it convenient to enter all your sequel in just one executeStatement or getRecordsForQuery call. If you don’t have any parameters, don’t enter anything after your SQL.

The results array is an Array of Dictionary’s where the ‘key’ is your tables column name, and the ‘value’ is your data obtained from SQLite. You can easily iterate through this array with a for loop or print it out directly or assign these Dictionary elements to custom data object Classes that you use in your View Controllers for model consumption.

    for dic in results as! [[String:AnyObject]] {
       print(“result = \(dic)”)
    }

SQLDataAccess will store, text, double, float, blob, Date, integer and long long integers. For Blobs you can store binary, varbinary, blob.

For Text you can store char, character, clob, national varying character, native character, nchar, nvarchar, varchar, variant, varying character, text.

For Dates you can store datetime, time, timestamp, date.

For Integers you can store bigint, bit, bool, boolean, int2, int8, integer, mediumint, smallint, tinyint, int.

For Doubles you can store decimal, double precision, float, numeric, real, double. Double has the most precision.

You can even store Nulls of type Null.

In ViewController.swift a more complex example is done showing how to insert a Dictionary as a 'Blob'. In addition SQLDataAccess understands native Swift Date() so you can insert these objects with out converting, and it will convert them to text and store them, and when retrieved convert them back from text to Date.

Of course the real power of SQLite is it's Transaction capability. Here you can literally queue up 400 SQL statements with parameters and insert them all at once which is really powerful since it's so fast. ViewController.swift also shows you an example of how to do this. All you're really doing is creating an Array of Dictionaries called 'sqlAndParams', in this Array your storing Dictionaries with two keys 'SQL' for the String sequel statement or query, and 'PARAMS' which is just an Array of native objects SQLite understands for that query. Each 'sqlParams' which is an individual Dictionary of sequel query plus parameters is then stored in the 'sqlAndParams' Array. Once you've created this array, you just call.

    let status = db.executeTransaction(sqlAndParams)
    if(status)
    {
        //Read Table AppInfo into an Array of Dictionaries for the above Transactions
        let results = db.getRecordsForQuery("select * from AppInfo ")
        NSLog("Results = \(results)")
    }

In addition all executeStatement and getRecordsForQuery methods can be done with simple String for SQL query and an Array for the parameters needed by the query.

    let sql : String = "insert into AppInfo (name,value,descrip) values(?,?,?)"
    let params : Array = ["SQLiteDemo","1.0.0","unencrypted"]
    let status = db.executeStatement(sql, withParameters: params)
    if(status)
    {
        //Read Table AppInfo into an Array of Dictionaries for the above Transactions
        let results = db.getRecordsForQuery("select * from AppInfo ")
        NSLog("Results = \(results)")
    }

An Objective-C version also exists and is called the same SQLDataAccess, so now you can choose to write your sequel in Objective-C or Swift. In addition SQLDataAccess will also work with SQLCipher, the present code isn't setup yet to work with it, but it's pretty easy to do, and an example of how to do this is actually in the Objective-C version of SQLDataAccess.

SQLDataAccess is a very fast and efficient class, and can be used in place of CoreData which really just uses SQLite as it's underlying data store without all the CoreData core data integrity fault crashes that come with CoreData.

The default namespace in Python is "__main__". When you use import scipy, Python creates a separate namespace as your module name. The rule in Pyhton is: when you want to call an attribute from another namespaces you have to use the fully qualified attribute name.

Another implementation that is also working with list of objects, not just strings:

JS:

var postData = {};
postData[values] = selectedValues ;

$.ajax({
    url: "/Home/SaveList",
    type: "POST",
    data: JSON.stringify(postData),
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function(data){
        alert(data.Result);
    }
});

Assuming that 'selectedValues' is Array of Objects.

In the controller the parameter is a list of corresponding ViewModels.

public JsonResult SaveList(List<ViewModel> values)
{    
    return Json(new { 
          Result = String.Format("Fist item in list: '{0}'", values[0].Name) 
    });
}

 static void Main()
     {
             for (int i=0; i<GetNames().Length; i++)
               {
                    Console.WriteLine (GetNames()[i]);
                }
     }

  static string[] GetNames()
   {
         string[] ret = {"Answer", "by", "Anonymous", "Pakistani"};
         return ret;
   }

php_value upload_max_filesize 30M is correct.

You will have to contact your hosters -- some don't allow you to change values in php.ini

You could just pass a static value (or a variable from *ngFor or whatever)

<button (click)="toggle(1)" class="someclass">
<button (click)="toggle(2)" class="someclass">

Typically one uses an abstract class to provide some incomplete functionality that will be fleshed out by concrete subclasses. It may provide methods that are used by its subclasses; it may also represent an intermediate node in the class hierarchy, to represent a common grouping of concrete subclasses, distinguishing them in some way from other subclasses of its superclass. Since an interface can't derive from a class, this is another situation where a class (abstract or otherwise) would be necessary, versus an interface.

A good rule of thumb is that only leaf nodes of a class hierarchy should ever be instantiated. Making non-leaf nodes abstract is an easy way of ensuring that.

Don't use SELECT COUNT(*) FROM TABLENAME, since that is a resource intensive operation. One should use SQL Server Dynamic Management Views or System Catalogs to get the row count information for all tables in a database.

Your error

InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

appears because you must call setRequestHeader after calling open. Simply move your setRequestHeader line below your open line (but before send):

xmlhttp.open("POST", url);
xmlhttp.setRequestHeader("x-filename", photoId);
xmlhttp.send(formData);

A suggestion - when using cross join please take care of the duplicate scenarios. For example in your case:

• Table 1 may have >1 columns as part of primary keys(say table1_id, id2, id3, table2_id)
• Table 2 may have >1 columns as part of primary keys(say table2_id, id3, id4)

since there are common keys between these two tables (i.e. foreign keys in one/other) - we will end up with duplicate results. hence using the following form is good:

WITH data_mined_table (col1, col2, col3, etc....) AS
SELECT DISTINCT col1, col2, col3, blabla
FROM table_1 (NOLOCK), table_2(NOLOCK))
SELECT * from data_mined WHERE data_mined_table.col1 = :my_param_value

Other way to get the minor version is:

SELECT extversion
FROM pg_catalog.pg_extension
WHERE extname='postgis'

The answers above are great, but I needed a simple example to alleviate some concerns that I have had in the past. I wanted to make sure it was indeed treating each column separately. I am now reassured and can't find what example had caused me concern. All columns ARE scaled separately as described by those above.

CODE

import pandas as pd
import scipy.stats as ss
from sklearn.preprocessing import StandardScaler


data= [[1, 1, 1, 1, 1],[2, 5, 10, 50, 100],[3, 10, 20, 150, 200],[4, 15, 40, 200, 300]]

df = pd.DataFrame(data, columns=['N0', 'N1', 'N2', 'N3', 'N4']).astype('float64')

sc_X = StandardScaler()
df = sc_X.fit_transform(df)

num_cols = len(df[0,:])
for i in range(num_cols):
    col = df[:,i]
    col_stats = ss.describe(col)
    print(col_stats)

OUTPUT

NOTE:

The scipy.stats module is correctly reporting the "sample" variance, which uses (n - 1) in the denominator. The "population" variance would use n in the denominator for the calculation of variance. To understand better, please see the code below that uses scaled data from the first column of the data set above:

Code

import scipy.stats as ss

sc_Data = [[-1.34164079], [-0.4472136], [0.4472136], [1.34164079]]
col_stats = ss.describe([-1.34164079, -0.4472136, 0.4472136, 1.34164079])
print(col_stats)
print()

mean_by_hand = 0
for row in sc_Data:
    for element in row:
        mean_by_hand += element
mean_by_hand /= 4

variance_by_hand = 0
for row in sc_Data:
    for element in row:
        variance_by_hand += (mean_by_hand - element)**2
sample_variance_by_hand = variance_by_hand / 3
sample_std_dev_by_hand = sample_variance_by_hand ** 0.5

pop_variance_by_hand = variance_by_hand / 4
pop_std_dev_by_hand = pop_variance_by_hand ** 0.5

print("Sample of Population Calcs:")
print(mean_by_hand, sample_variance_by_hand, sample_std_dev_by_hand, '\n')
print("Population Calcs:")
print(mean_by_hand, pop_variance_by_hand, pop_std_dev_by_hand)

Output

Try it as below:

You can use the the Shade Plugin to create an uber jar in which you can bundle all your 3rd party dependencies.

As of "X-"-Prefix was deprecated. (see: https://tools.ietf.org/html/rfc6648)

We found the "Accept-Ranges" as being the best bet to map the pagination ranging: https://tools.ietf.org/html/rfc7233#section-2.3 As the "Range Units" may either be "bytes" or "token". Both do not represent a custom data type. (see: https://tools.ietf.org/html/rfc7233#section-4.2) Still, it is stated that

HTTP/1.1 implementations MAY ignore ranges specified using other units.

Which indicates: using custom Range Units is not against the protocol, but it MAY be ignored.

This way, we would have to set the Accept-Ranges to "members" or whatever ranged unit type, we'd expect. And in addition, also set the Content-Range to the current range. (see: https://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.12)

Either way, I would stick to the recommendation of RFC7233 (https://tools.ietf.org/html/rfc7233#page-8) to send a 206 instead of 200:

If all of the preconditions are true, the server supports the Range
header field for the target resource, and the specified range(s) are
valid and satisfiable (as defined in Section 2.1), the server SHOULD
send a 206 (Partial Content) response with a payload containing one
or more partial representations that correspond to the satisfiable
ranges requested, as defined in Section 4.

So, as a result, we would have the following HTTP header fields:

For Partial Content:

206 Partial Content
Accept-Ranges: members
Content-Range: members 0-20/100

For full Content:

200 OK
Accept-Ranges: members
Content-Range: members 0-20/20

I 2nd Chad Grant's answer and also submit this blog article [removed dead link] for your viewing pleasure.

BigInteger would only be used if you know it will not be a decimal and there is a possibility of the long data type not being large enough. BigInteger has no cap on its max size (as large as the RAM on the computer can hold).

From here.

It is implemented using an int[]:

  110       /**
  111        * The magnitude of this BigInteger, in <i>big-endian</i> order: the
  112        * zeroth element of this array is the most-significant int of the
  113        * magnitude.  The magnitude must be "minimal" in that the most-significant
  114        * int ({@code mag[0]}) must be non-zero.  This is necessary to
  115        * ensure that there is exactly one representation for each BigInteger
  116        * value.  Note that this implies that the BigInteger zero has a
  117        * zero-length mag array.
  118        */
  119       final int[] mag;

From the source

From the Wikipedia article Arbitrary-precision arithmetic:

Several modern programming languages have built-in support for bignums, and others have libraries available for arbitrary-precision integer and floating-point math. Rather than store values as a fixed number of binary bits related to the size of the processor register, these implementations typically use variable-length arrays of digits.

I found myself needing to create a dictionary of three lists (latitude, longitude, and a value), with the following doing the trick:

> lat = [45.3,56.2,23.4,60.4]
> lon = [134.6,128.7,111.9,75.8]
> val = [3,6,2,5]
> dict(zip(zip(lat,lon),val))
{(56.2, 128.7): 6, (60.4, 75.8): 5, (23.4, 111.9): 2, (45.3, 134.6): 3}

or similar to the above examples:

> list1 = [1,2,3,4]
> list2 = [1,2,3,4]
> list3 = ['a','b','c','d']
> dict(zip(zip(list1,list2),list3))
{(3, 3): 'c', (4, 4): 'd', (1, 1): 'a', (2, 2): 'b'}

Note: Dictionaries are "orderless", but if you would like to view it as "sorted", refer to THIS question if you'd like to sort by key, or THIS question if you'd like to sort by value.

To iterate through the keys of an object, use a for .. in loop:

for (var key in json_obj) {
    if (json_obj.hasOwnProperty(key)) {
        // do something with `key'
    }
}

To test all elements for empty children, you can use a recursive approach: iterate through all elements and recursively test their children too.

Removing a property of an object can be done by using the delete keyword:

var someObj = {
    "one": 123,
    "two": 345
};
var key = "one";
delete someObj[key];
console.log(someObj); // prints { "two": 345 }

I found this question when searching for You are in 'detached HEAD' state.

After analyzing what I had done to get here, as compared with what I had done in the past, I discovered that I had made a mistake.

My normal flow is:

git checkout master
git fetch
git checkout my-cool-branch
git pull

This time I did:

git checkout master
git fetch
git checkout origin/my-cool-branch
# You are in 'detached HEAD' state.

The problem is that I accidentally did:

git checkout origin/my-cool-branch

Rather than:

git checkout my-cool-branch

The fix (in my situation) was simply to run the above command and then continue the flow:

git checkout my-cool-branch
git pull

The following code allows to upload gif, png, jpg, jpeg and bmp files.

var extension = $('#your_file_id').val().split('.').pop().toLowerCase();

if($.inArray(extension, ['gif','png','jpg','jpeg','bmp']) == -1) {
    alert('Sorry, invalid extension.');
    return false;
}

I'm aware that I'm quite late for the party, but I consider that the library from Phillip Allan-Harding, it's the best one for this case and similar ones.

You only need a small piece of code like this one:

private const string LOGIN = "mamy";
private const string DOMAIN = "mongo";
private const string PASSWORD = "HelloMongo2017";

private void DBConnection()
{
    using (Impersonator user = new Impersonator(LOGIN, DOMAIN, PASSWORD, LogonType.LOGON32_LOGON_NEW_CREDENTIALS, LogonProvider.LOGON32_PROVIDER_WINNT50))
    {
    }
}

And add his class:

.NET (C#) Impersonation with Network Credentials

My example can be used if you require the impersonated logon to have network credentials, but it has more options.

The following is a nice expedient solution that works with GitHub for checking out the PR branch from another user's fork. You need to know the pull request ID (which GitHub displays along with the PR title).

Example:

Fixing your insecure code #8
alice wants to merge 1 commit into your_repo:master from her_repo:branch

git checkout -b <branch>
git pull origin pull/8/head

Substitute your remote if different from origin.
Substitute 8 with the correct pull request ID.

From the documentation:

It is necessary to keep in mind that the browsers do not know how to correctly show this error.

I suspect this is what's happening, if you inspect the HTTP to-and-fro using tools such as Firebug or Live HTTP Headers (both Firefox extensions) you'll be able to see what's really going on.

You can just specify the generic octet-stream MIME type:

public FileResult Download()
{
    byte[] fileBytes = System.IO.File.ReadAllBytes(@"c:\folder\myfile.ext");
    string fileName = "myfile.ext";
    return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
}

"When programming with C# you don’t usually need to worry about the underlying target platform. There are however a few cases when the Application and OS architecture can affect program logic, change functionality and cause unexpected exceptions."

"It is common misconception that selecting a specific target will result in the compiler generating platform specific code. This is not the case and instead it simply sets a flag in the assembly’s CLR header. This information can be easily extracted, and modified, using Microsoft’s CoreFlags tool"

    contents: { 
      1: {
        text: {$set: action.payload}
      }
    }
  });

Although I would imagine you'd probably be doing something more like this?

case 'SOME_ACTION':
  return update(state, { 
    contents: { 
      [action.id]: {
        text: {$set: action.payload}
      }
    }
  });

Depends on the platform. On Windows it is actually "\r\n".

From MSDN:

A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.

You should be checking the root directory and not the app directory.

Look in $ROOT/storage/laravel.log not app/storage/laravel.log, where root is the top directory of the project.

Your solution might be to add the original IP and/or hostname also:

ALLOWED_HOSTS = [
  'localhost',
  '127.0.0.1',
  '111.222.333.444',
  'mywebsite.com']

The condition to be satisfied is that the host header (or X-Forwarded-Host if USE_X_FORWARDED_HOST is enabled) should match one of the values in ALLOWED_HOSTS.

I wanted to comment on @Ionica Bizau, but I don't have enough reputation.
To give a reply to your question about javascript code:
What you need to do is get the parent's element height (minus any elements that take up space) and apply that to the child elements.

function wrapperHeight(){
    var height = $(window).outerHeight() - $('#header').outerHeight(true);
    $('.wrapper').css({"max-height":height+"px"});      
}

Note
window could be replaced by ".container" if that one has no floated children or has a fix to get the correct height calculated. This solution uses jQuery.

On Windows/Linux press Alt+F3.

HTML:

<form id="myform">
    <input id="email" oninvalid="InvalidMsg(this);" name="email" oninput="InvalidMsg(this);"  type="email" required="required" />
    <input type="submit" />
</form>

JAVASCRIPT :

function InvalidMsg(textbox) {
    if (textbox.value == '') {
        textbox.setCustomValidity('Required email address');
    }
    else if (textbox.validity.typeMismatch){{
        textbox.setCustomValidity('please enter a valid email address');
    }
    else {
       textbox.setCustomValidity('');
    }
    return true;

Use Arrays.copyOf my friend.

If you just want the table to auto-layout

Without using max-width, or percentage column widths, or table-layout: fixed etc.

https://jsfiddle.net/tturadqq/

How it works:

Step 1: Just let the table auto-layout do its thing.

When there's one or more columns with a lot of text, it will shrink the other columns as much as possible, then wrap the text of the long columns:

Step 2: Wrap cell contents in a div, then set that div to max-height: 1.1em

(the extra 0.1em is for characters which render a bit below the text base, like the tail of 'g' and 'y')

Step 3: Set title on the divs

This is good for accessibility, and is necessary for the little trick we'll use in a moment.

Step 4: Add a CSS ::after on the div

This is the tricky bit. We set a CSS ::after, with content: attr(title), then position that on top of the div and set text-overflow: ellipsis. I've coloured it red here to make it clear.

(Note how the long column now has a tailing ellipsis)

Step 5: Set the colour of the div text to transparent

And we're done!

Here:

def random_color():
    rgbl=[255,0,0]
    random.shuffle(rgbl)
    return tuple(rgbl)

The result is either red, green or blue. The method is not applicable to other sets of colors though, where you'd have to build a list of all the colors you want to choose from and then use random.choice to pick one at random.

For another as Latin languages for example Cyrillic you can use something like this:

FileReader fr = new FileReader("src/text.txt", StandardCharsets.UTF_8);

and be sure that your .txt file is saved with UTF-8 (but not as default ANSI) format. Cheers!

It starts working because on the base.py you have all information needed in a basic settings file. You need the line:

SECRET_KEY = '8lu*6g0lg)9z!ba+a$ehk)xt)x%rxgb$i1&022shmi1jcgihb*'

So it works and when you do from base import *, it imports SECRET_KEY into your development.py.

You should always import basic settings before doing any custom settings.

EDIT: Also, when django imports development from your package, it initializes all variables inside base since you defined from base import * inside __init__.py

sounds like you're looking for setInterval. It's as easy as this:

function FetchData() {
  // do something
}
setInterval(FetchData, 60000);

if you only want to call something once, theres setTimeout.

This works without having to use scrot or ImageMagick.

pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

You're declaring a virtual function and not defining it:

virtual void calculateCredits();

Either define it or declare it as:

virtual void calculateCredits() = 0;

Or simply:

virtual void calculateCredits() { };

Read more about vftable: http://en.wikipedia.org/wiki/Virtual_method_table

Try doing this instead:

function enable(id)
{
    var eleman = document.getElementById(id);
    eleman.removeAttribute("disabled");        
}

To enable an element you have to remove the disabled attribute. Setting it to false still means it is disabled.

a = 0.000006;
b = 6;
c = a/b;

textbox.Text = c.ToString("0.000000");

As you requested:

textbox.Text = c.ToString("0.######");

This will only display out to the 6th decimal place if there are 6 decimals to display.

In my case, I've a sampleViewController's view added as a subview, then tries to present a popover from the view of sampleViewController (here self instead a UIViewController instance):

[self.view addSubview:sampleViewController.view];

The right way should be below:

// make sure the vc has been added as a child view controller as well
[self addChildViewController:sampleViewController];
[self.view addSubview:sampleViewController.view];
[sampleViewController didMoveToParentViewController:self];

B.t.w., this also works for the case that present a popover form a tableview cell, you just need to make sure the tableview controller has been added as child view controller as well.

select field1, field2, NewField = 'example' from table1 

This works for me.

private OnClickListener mDisconnectListener;
mDisconnectListener = new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

        }
    };

...

... onCreateView(...){

mButtonDisconnect = (Button) rootView.findViewById(R.id.button_disconnect);
mButtonDisconnect.setOnClickListener(mDisconnectListener);
...
}

I figured out that this behaves like a mousedown event:

button:active:hover {}

Once I have detected Android in the user agent, this is how I differentiate between tablet and smartphone browsers (this is using Python, but is similarly simple for other programming languages):

if ("Android" in agent):
  if ("Mobile" in agent):
    deviceType = "Phone"
  else:
    deviceType = "Tablet"

UPDATED: to reflect use of Chrome on Android, as per comments below.

Here's a good guide: http://api.rubyonrails.org/classes/ActionView/Base.html

Here's a simple single threaded sleep based version that drifts, but tries to auto-correct when it detects drift.

NOTE: This will only work if the following 3 reasonable assumptions are met:

1. The time period is much larger than the execution time of the function being executed
2. The function being executed takes approximately the same amount of time on each call
3. The amount of drift between calls is less than a second

-

from datetime import timedelta
from datetime import datetime

def exec_every_n_seconds(n,f):
    first_called=datetime.now()
    f()
    num_calls=1
    drift=timedelta()
    time_period=timedelta(seconds=n)
    while 1:
        time.sleep(n-drift.microseconds/1000000.0)
        current_time = datetime.now()
        f()
        num_calls += 1
        difference = current_time - first_called
        drift = difference - time_period* num_calls
        print "drift=",drift

I think JavaScript performance (time) testing is quite enough. I found a very handy article about JavaScript performance testing here.

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)

If it is possible to change the sequence of the lines you could do:

1. sort line with Edit -> Line Operations -> Sort Lines Lexicographically ascending
2. do a Find / Replace:
   • Find What: ^(.*\r?\n)\1+
   • Replace with: (Nothing, leave empty)
   • Check Regular Expression in the lower left
   • Click Replace All

How it works: The sorting puts the duplicates behind each other. The find matches a line ^(.*\r?\n) and captures the line in \1 then it continues and tries to find \1 one or more times (+) behind the first match. Such a block of duplicates (if it exists) is replaced with nothing.

The \r?\n should deal nicely with Windows and Unix lineendings.

For others, if clearfix does not solve this for you, add margins to the non-floated sibling that is/are the same as the width(s) of the floated sibling(s).

All you need to do is to override getParams method in Request class. I had the same problem and I searched through the answers but I could not find a proper one. The problem is unlike get request, post parameters being redirected by the servers may be dropped. For instance, read this. So, don't risk your requests to be redirected by webserver. If you are targeting http://example/myapp , then mention the exact address of your service, that is http://example.com/myapp/index.php.
Volley is OK and works perfectly, the problem stems from somewhere else.

   .controller('pieChartController', ['$scope', '$http', '$httpParamSerializerJQLike', function($scope, $http, $httpParamSerializerJQLike) {
        var data = {
                TimeStamp : "2016-04-25 12:50:00"
        };
        $http({
            method: 'POST',
            url: 'serverutilizationreport',
            headers: {'Content-Type': 'application/x-www-form-urlencoded'},
            data: $httpParamSerializerJQLike(data),
        }).success(function () {});
    }
  ]);

You can indeed not define the filter execution order using @WebFilter annotation. However, to minimize the web.xml usage, it's sufficient to annotate all filters with just a filterName so that you don't need the <filter> definition, but just a <filter-mapping> definition in the desired order.

For example,

@WebFilter(filterName="filter1")
public class Filter1 implements Filter {}

@WebFilter(filterName="filter2")
public class Filter2 implements Filter {}

with in web.xml just this:

<filter-mapping>
    <filter-name>filter1</filter-name>
    <url-pattern>/url1/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>filter2</filter-name>
    <url-pattern>/url2/*</url-pattern>
</filter-mapping>

If you'd like to keep the URL pattern in @WebFilter, then you can just do like so,

@WebFilter(filterName="filter1", urlPatterns="/url1/*")
public class Filter1 implements Filter {}

@WebFilter(filterName="filter2", urlPatterns="/url2/*")
public class Filter2 implements Filter {}

but you should still keep the <url-pattern> in web.xml, because it's required as per XSD, although it can be empty:

<filter-mapping>
    <filter-name>filter1</filter-name>
    <url-pattern />
</filter-mapping>
<filter-mapping>
    <filter-name>filter2</filter-name>
    <url-pattern />
</filter-mapping>

Regardless of the approach, this all will fail in Tomcat until version 7.0.28 because it chokes on presence of <filter-mapping> without <filter>. See also Using Tomcat, @WebFilter doesn't work with <filter-mapping> inside web.xml

This works

Guid.NewGuid()

Eventually calls CoCreateGuid (a COM call to Ole32) (reference here) and the actual work is done by UuidCreate.

Guid.Empty is meant to be used to check if a Guid contains all zeroes. This could also be done via comparing the value of the Guid in question with new Guid()

So, if you need a unique identifier, the answer is Guid.NewGuid()

First off, in order to have any image "resize" to fit a picturebox, you can set the PictureBox.SizeMode = PictureBoxSizeMode.StretchImage

If you want to do clipping of the image beforehand (i.e. cut off sides or top and bottom), then you need to clearly define what behavior you want (start at top, fill the height of the pciturebox and crop the rest, or start at the bottom, fill the height of the picturebox to the top, etc), and it should be fairly simple to use the Height / Width properties of both the picturebox and the image to clip the image and get the effect you are looking for.

Mike Nereson has this to say on his blog at:

http://blog.codehangover.com/load-multiple-contexts-into-spring/

There are a couple of ways to do this.

1. web.xml contextConfigLocation

Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value>
          applicationContext1.xml
          applicationContext2.xml
      </param-value>
  </context-param>

  <listener>
      <listener-class>
          org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>

The above uses carriage returns. Alternatively, yo could just put in a space.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value> applicationContext1.xml applicationContext2.xml </param-value>
  </context-param>

  <listener>
      <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>
  </listener>

2. applicationContext.xml import resource

Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.

In applicationContext.xml you might have…

  <!-- hibernate configuration and mappings -->
  <import resource="applicationContext-hibernate.xml"/>

  <!-- ldap -->
  <import resource="applicationContext-ldap.xml"/>

  <!-- aspects -->
  <import resource="applicationContext-aspects.xml"/>

Which strategy should you use?

1. I always prefer to load up via web.xml.

Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay loosely coupled, so that in the future I can extract a package or vertical layer and move it to its own module.

2. If you are loading contexts into a non-web application, I would use the import resource.

In case you are getting 530 password incorrect

1 more step needed

in file /etc/shells

Add the following line

/bin/false

Use like ..

<div style="background-image: url(../images/test-background.gif); height: 200px; width: 400px; border: 1px solid black;">Example of a DIV element with a background image:</div>
<div style="background-image: url(../images/test-background.gif); height: 200px; width: 400px; border: 1px solid black;"> </div>

df3.set_value(1, 'B', abc) works for any dataframe. Take care of the data type of column 'B'. Eg. a list can not be inserted into a float column, at that case df['B'] = df['B'].astype(object) can help.

Ned Deily's solution works perfectly fine, provided your user is allowed to sudo.

If he's not, you can su to an admin account, then use his dscl . append /Groups/_developer GroupMembership $user, where $user is the username.

However, I mistakenly thought it did not because I wrongly typed in the user's name in the command and it silently fails.

Therefore, after entering this command, you should proof-check it. This will check if $user is in $group, where the variables represent respectively the user name and the group name.

dsmemberutil checkmembership -U $user -G $group

This command will either print the message user is not a member of the group or user is a member of the group.

I have posted this as a separate answer as it is unrelated to my existing answer.

This issue recently cropped up again for accessing a parent from an iframe referencing a subdomain and the existing fixes did not work.

This time the answer was to modify the document.domain of the parent page and the iframe to be the same. This will fool the same origin policy checks into thinking they co-exist on exactly the same domain (subdomains are considered a different host and fail the same origin policy check).

Insert the following to the <head> of the page in the iframe to match the parent domain (adjust for your doctype).

<script>
    document.domain = "mydomain.com";
</script>

Please note that this will throw an error on localhost development, so use a check like the following to avoid the error:

if (!window.location.href.match(/localhost/gi)) {
    document.domain = "mydomain.com";
} 

Any other places you use TimerEventProcessor or Counter?

Anyway, you can not rely on the Event being exactly delivered one per second. The time may vary, and the system will not make sure the average time is correct.

So instead of _Counter, you should use:

 // when starting the timer:
 DateTime _started = DateTime.UtcNow;

 // in TimerEventProcessor:
 seconds = (DateTime.UtcNow-started).TotalSeconds;
 Label.Text = seconds.ToString();

Note: this does not solve the Problem of TimerEventProcessor being called to often, or _Counter incremented to often. it merely masks it, but it is also the right way to do it.

It's possible that the modules are installed, but your PHP.ini still points to an old directory.

Check the contents of /usr/lib/php/extensions. In mine, there were two directories: no-debug-non-zts-20060613 and no-debug-non-zts-20060613. Around line 428 of your php.ini, change:

extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613"

to

extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20090626"

Then restart apache. This should resolve the issue.

Just check our own JSTL wiki page for the proper download links and crystal clear installation instructions.

Put your mouse above the [jstl] tag which you put on the question yourself until a black box shows up and click therein the info link.

Then scroll a bit down to JSTL versions information until you find download link to JSTL 1.2 (or 1.2.1).

Finally just drop exactly that file in webapp's /WEB-INF/lib.

This way the taglib declaration must not give any errors anymore and the JSTL tags and functions should just work.

Apart from the previous use cases, you can also use Docker Compose to create directories in case you want to make new dummy folders on docker-compose up:

    volumes:
  - .:/ftp/
  - /ftp/node_modules
  - /ftp/files

Here https://toddmotto.com/mastering-the-module-pattern you can find the pattern thoroughly explained. I would add that the second thing about modular JavaScript is how to structure your code in multiple files. Many folks may advice you here to go with AMD, yet I can say from experience that you will end up on some point with slow page response because of numerous HTTP requests. The way out is pre-compilation of your JavaScript modules (one per file) into a single file following CommonJS standard. Take a look at samples here http://dsheiko.github.io/cjsc/

You can create a function with the pattern ShouldSerialize{PropertyName} which tells the XmlSerializer if it should serialize the member or not.

For example, if your class property is called MyNullableInt you could have

public bool ShouldSerializeMyNullableInt() 
{
  return MyNullableInt.HasValue;
}

Here is a full sample

public class Person
{
  public string Name {get;set;}
  public int? Age {get;set;}
  public bool ShouldSerializeAge()
  {
    return Age.HasValue;
  }
}

Serialized with the following code

Person thePerson = new Person(){Name="Chris"};
XmlSerializer xs = new XmlSerializer(typeof(Person));
StringWriter sw = new StringWriter();
xs.Serialize(sw, thePerson);

Results in the followng XML - Notice there is no Age

<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Name>Chris</Name>
</Person>

file = open("myfile.txt", "r")
lines = file.readlines()
str = ''                                     #string declaration

for i in range(len(lines)):
    str += lines[i].rstrip('\n') + ' '

print str

You don't mention if this is an anonymous PL/SQL block or a declarative one ie. Package, Procedure or Function. However, in PL/SQL a COMMIT must be explicitly made to save your transaction(s) to the database. The COMMIT actually saves all unsaved transactions to the database from your current user's session.

If an error occurs the transaction implicitly does a ROLLBACK.

This is the default behaviour for PL/SQL.

• Controller will handle the navigation between the different views. Your mappings request mappings are handled with the help of controller.
• Service interacts directly with the repository where usually the business logic is performed. You can add, delete, remove etc at the service layer

var result = Regex.Replace("123- abcd33", @"[0-9\-]", string.Empty);

In my case is a cookie-related issue, I had many cookies with value extremely big, and that was causing the problem.

You can replicate this issue here on stackoverflow.com, just open the console and type this:

[ ...Array(5) ].forEach((i, idx) => {
    document.cookie = `stackoverflow_cookie${idx}=${'a'.repeat(4000)}`;
});

What is that?

I am creating 5 cookies with a string of length or value of 4000 bytes; then reload the page and you will see the same issue.

I tried it on google.com and you'll get the error but they automatically clear the cookies for you, which is a nice fallback to start fresh.

The Actual solution of this problem is changing first line in web.php

  printf("%d\n", (char)255);          // prints -1   -> 255 is cast to char where it is -1
  printf("%d\n", '\n');               // prints 10   -> Ascii newline has VALUE 10. The char 10 is integer promoted to int 10
  printf("%d\n", sizeof('\n'));       // prints 4    -> Ascii newline is char, but integer promoted to int. And sizeof(int) is 4 (on many architectures)
  printf("%d\n", sizeof((char)'\n')); // prints 1    -> Switch off integer promotion via cast!

  return 0;
}

The same as Brian, but add to this answer from tstempko:

https://sqa.stackexchange.com/questions/3481/quicker-way-to-assert-that-an-element-does-not-exist

So I tried and it works quickly:

driver.implicitly_wait(0)

if driver.find_element_by_id("show_reflist"):        
 driver.find_element_by_id("show_reflist").find_element_by_tag_name("img").click()

after this I restore my default value

driver.implicitly_wait(30)

You can also use a Subject and trigger its next() function from promise. See sample below:

Add code like below ( I used service )

class UserService {_x000D_
  private createUserSubject: Subject < any > ;_x000D_
_x000D_
  createUserWithEmailAndPassword() {_x000D_
    if (this.createUserSubject) {_x000D_
      return this.createUserSubject;_x000D_
    } else {_x000D_
      this.createUserSubject = new Subject < any > ();_x000D_
      firebase.auth().createUserWithEmailAndPassword(email,_x000D_
          password)_x000D_
        .then(function(firebaseUser) {_x000D_
          // do something to update your UI component_x000D_
          // pass user object to UI component_x000D_
          this.createUserSubject.next(firebaseUser);_x000D_
        })_x000D_
        .catch(function(error) {_x000D_
          // Handle Errors here._x000D_
          var errorCode = error.code;_x000D_
          var errorMessage = error.message;_x000D_
          this.createUserSubject.error(error);_x000D_
          // ..._x000D_
        });_x000D_
    }_x000D_
_x000D_
  }_x000D_
}

Create User From Component like below

class UserComponent {_x000D_
  constructor(private userService: UserService) {_x000D_
    this.userService.createUserWithEmailAndPassword().subscribe(user => console.log(user), error => console.log(error);_x000D_
    }_x000D_
  }

I don't know if this would work because I'm pretty sure that the keys aren't stored in the order they are added, but you could cast the KeysCollection to a List and then get the last key in the list... but it would be worth having a look.

The only other thing I can think of is to store the keys in a lookup list and add the keys to the list before you add them to the dictionary... it's not pretty tho.

Hmmm, perhaps another option would be to use something like sshfs (there an sshfs for Mac too). Once your router is mounted you can just copy the files outright. I'm not sure if that works for your particular application but it's a nice solution to keep handy.

You might need a GLOBAL TEMPORARY TABLE.

In Oracle these are created once and then when invoked the data is private to your session.

Oracle Documentation Link

Try something like this...

CREATE GLOBAL TEMPORARY TABLE temp_number
   ( number_column   NUMBER( 10, 0 )
   )
   ON COMMIT DELETE ROWS;

BEGIN 
   INSERT INTO temp_number
      ( number_column )
      ( select distinct sgbstdn_pidm 
          from sgbstdn 
         where sgbstdn_majr_code_1 = 'HS04' 
           and sgbstdn_program_1 = 'HSCOMPH' 
      ); 

    FOR pidms_rec IN ( SELECT number_column FROM temp_number )
    LOOP 
        -- Do something here
        NULL; 
    END LOOP; 
END; 
/

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

UPDATE:

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

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

The whole point of using a mapping technology like Jackson is that you can use Objects (you don't have to parse the JSON yourself).

Define a Java class that resembles the JSON you will be expecting.

e.g. this JSON:

{
"foo" : ["abc","one","two","three"],
"bar" : "true",
"baz" : "1"
}

could be mapped to this class:

public class Fizzle{
    private List<String> foo;
    private boolean bar;
    private int baz;
    // getters and setters omitted
}

Now if you have a Controller method like this:

@RequestMapping("somepath")
@ResponseBody
public Fozzle doSomeThing(@RequestBody Fizzle input){
    return new Fozzle(input);
}

and you pass in the JSON from above, Jackson will automatically create a Fizzle object for you, and it will serialize a JSON view of the returned Object out to the response with mime type application/json.

For a full working example see this previous answer of mine.

To correctly parse the string given in the question without changing it, use the following:

using System.Globalization;

string dateString = "Tue, 1 Jan 2008 00:00:00 UTC";
DateTime parsedDate = DateTime.ParseExact(dateString, "ddd, d MMM yyyy hh:mm:ss UTC", CultureInfo.CurrentCulture, DateTimeStyles.AssumeUniversal);

This implementation uses a string to specify the exact format of the date string that is being parsed. The DateTimeStyles parameter is used to specify that the given string is a coordinated universal time string.

For a list, you could use a list comp. For example, to make b a copy of a without the 3rd element:

a = range(10)[::-1]                       # [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
b = [x for i,x in enumerate(a) if i!=3]   # [9, 8, 7, 5, 4, 3, 2, 1, 0]

This is very general, and can be used with all iterables, including numpy arrays. If you replace [] with (), b will be an iterator instead of a list.

Or you could do this in-place with pop:

a = range(10)[::-1]     # a = [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
a.pop(3)                # a = [9, 8, 7, 5, 4, 3, 2, 1, 0]

In numpy you could do this with a boolean indexing:

a = np.arange(9, -1, -1)     # a = array([9, 8, 7, 6, 5, 4, 3, 2, 1, 0])
b = a[np.arange(len(a))!=3]  # b = array([9, 8, 7, 5, 4, 3, 2, 1, 0])

which will, in general, be much faster than the list comprehension listed above.

The JUnit way is to do this at run-time is org.junit.Assume.

 @Before
 public void beforeMethod() {
     org.junit.Assume.assumeTrue(someCondition());
     // rest of setup.
 }

You can do it in a @Before method or in the test itself, but not in an @After method. If you do it in the test itself, your @Before method will get run. You can also do it within @BeforeClass to prevent class initialization.

An assumption failure causes the test to be ignored.

Edit: To compare with the @RunIf annotation from junit-ext, their sample code would look like this:

@Test
public void calculateTotalSalary() {
    assumeThat(Database.connect(), is(notNull()));
    //test code below.
}

Not to mention that it is much easier to capture and use the connection from the Database.connect() method this way.

   <script type="text/JavaScript">  
function validate() 
{
if( document.form1.quali.value == "-1" )
   {
     alert( "Please select qualification!" );
     return false;
   }
}

</script>
<form name="form1" method="post" action="" onsubmit="return validate(this);">
<select name="quali" id="quali" ">
        <option value="-1" selected="selected">select</option>
        <option value="1">Graduate</option>
        <option value="2">Post Graduate</option>
      </select> 
</form>





// this code works 110% tested by me after many complex jquery method validation but it is simple javascript method plz try this if u fail in drop down required validation//

You can use the first method:

$('li').first()

http://api.jquery.com/first/

btw I agree with Nick Craver -- use document.getElementById()...

this is server configuration, set up config.addAllowedHeader("*"); in the CorsConfiguration.

You need to add the following line into your Apache config file:

AddType application/x-httpd-php .htm .html

You also need two other things:

1. Allow Overridding

   In your_site.conf file (e.g. under /etc/apache2/mods-available in my case), add the following lines:

   <Directory "<path_to_your_html_dir(in my case: /var/www/html)>">
       AllowOverride All
   </Directory>
   

2. Enable Rewrite Mod

   Run this command on your machine:

   sudo a2enmod rewrite 
   

   After any of those steps, you should restart apache:

   sudo service apache2 restart
   

Obligatory jQuery solution. Finds and sets the title attribute to foo. Note this selects a single element since I'm doing it by id, but you could easily set the same attribute on a collection by changing the selector.

$('#element').attr( 'title', 'foo' );

If I use Firefox then screen.width and screen.height works fine but in IE and Chrome they don't work properly instead it opens with the minimum size.

And yes I tried giving too large numbers too like 10000 for both height and width but not exactly the maximized effect.

For Ubuntu default version is /usr/lib/gradle/default. In case of update, you don't need to reassign link in idea/studio.

You need to use cast. I see the other answers, and they will really work, but as the tag is C++ I'd suggest you to use static_cast:

float m = static_cast< float >( a.y - b.y ) / static_cast< float >( a.x - b.x );

What you want is a SQL case statement. The form of these is either:

  select case [expression or column]
  when [value] then [result]
  when [value2] then [result2]
  else [value3] end

or:

  select case 
  when [expression or column] = [value] then [result]
  when [expression or column] = [value2] then [result2]
  else [value3] end

In your example you are after:

declare @temp as varchar(100)
set @temp='Measure'

select case @temp 
   when 'Measure' then Measure 
   else OtherMeasure end
from Measuretable

If you created the DLL using .net 4.5 , then copy and paste this command on command prompt.

 %SystemRoot%\Microsoft.NET\Framework\v4.0.30319\regasm.exe MyAssembly.dll

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8"))); //remove the parameter UTF-8 if you don't want to specify the Encoding type.

this works well for me even though the XML structure is complex.

And please make sure your xmlString is valid for XML, notice the escape character should be added "\" at the front.

The main problem might not come from the attributes.

I'm not sure what the original poster is asking exactly. Since indexOf(...) and contains(...) both probably use loops internally, perhaps he's looking to see if this is possible at all without a loop? I can think of two ways off hand, one would of course be recurrsion:

public boolean containsChar(String s, char search) {
    if (s.length() == 0)
        return false;
    else
        return s.charAt(0) == search || containsChar(s.substring(1), search);
}

The other is far less elegant, but completeness...:

/**
 * Works for strings of up to 5 characters
 */
public boolean containsChar(String s, char search) {
    if (s.length() > 5) throw IllegalArgumentException();

    try {
        if (s.charAt(0) == search) return true;
        if (s.charAt(1) == search) return true;
        if (s.charAt(2) == search) return true;
        if (s.charAt(3) == search) return true;
        if (s.charAt(4) == search) return true;
    } catch (IndexOutOfBoundsException e) {
        // this should never happen...
        return false;
    }
    return false;
}

The number of lines grow as you need to support longer and longer strings of course. But there are no loops/recurrsions at all. You can even remove the length check if you're concerned that that length() uses a loop.

The CBO builds a decision tree, estimating the costs of each possible execution path available per query. The costs are set by the CPU_cost or I/O_cost parameter set on the instance. And the CBO estimates the costs, as best it can with the existing statistics of the tables and indexes that the query will use. You should not tune your query based on cost alone. Cost allows you to understand WHY the optimizer is doing what it does. Without cost you could figure out why the optimizer chose the plan it did. Lower cost does not mean a faster query. There are cases where this is true and there will be cases where this is wrong. Cost is based on your table stats and if they are wrong the cost is going to be wrong.

When tuning your query, you should take a look at the cardinality and the number of rows of each step. Do they make sense? Is the cardinality the optimizer is assuming correct? Is the rows being return reasonable. If the information present is wrong then its very likely the optimizer doesn't have the proper information it needs to make the right decision. This could be due to stale or missing statistics on the table and index as well as cpu-stats. Its best to have stats updated when tuning a query to get the most out of the optimizer. Knowing your schema is also of great help when tuning. Knowing when the optimizer chose a really bad decision and pointing it in the correct path with a small hint can save a load of time.

One correct way to get selected value would be

var selected_value = $('#fruit_name').val()

And then you should do

if(selected_value) { ... }

You can define a variable @Result to fill your data in it

DECLARE @Result AS INT

IF EXISTS (SELECT * FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx') 
SET @Result = 1 
else
SET @Result = 2

You can do so. However, you can't assign to this. Thus the reason you state for doing this, "I want to change the view," seems very questionable. The better method, in my opinion, would be for the object that holds the view to replace that view.

Of course, you're using RAII objects and so you don't actually need to call delete at all...right?

I would suggest everytime when using global check if the variable is already define by simply check

if (!global.logger){
  global.logger = require('my_logger');
}

I've found it to have better performance

What should happen in the case of overflow? If you want it to just get to the bottom of the window, use absolute positioning:

div {
  position: absolute;
  top: 300px;
  bottom: 0px;
  left: 30px;
  right: 30px;
}

This will put the DIV 30px in from each side, 300px from the top of the screen, and flush with the bottom. Add an overflow:auto; to handle cases where the content is larger than the div.

vueObject.$forceUpdate();

why don't you use forceUpdate method?

import os.path

dirname = os.path.dirname(__file__) or '.'

It is important to understand that accessors restrict access to variable, but not their content. In ruby, like in some other OO languages, every variable is a pointer to an instance. So if you have an attribute to an Hash, for example, and you set it to be "read only" you always could change its content, but not the content of pointer. Look at this:

irb(main):024:0> class A
irb(main):025:1> attr_reader :a
irb(main):026:1> def initialize
irb(main):027:2> @a = {a:1, b:2}
irb(main):028:2> end
irb(main):029:1> end
=> :initialize
irb(main):030:0> a = A.new
=> #<A:0x007ffc5a10fe88 @a={:a=>1, :b=>2}>
irb(main):031:0> a.a
=> {:a=>1, :b=>2}
irb(main):032:0> a.a.delete(:b)
=> 2
irb(main):033:0> a.a
=> {:a=>1}
irb(main):034:0> a.a = {}
NoMethodError: undefined method `a=' for #<A:0x007ffc5a10fe88 @a={:a=>1}>
        from (irb):34
        from /usr/local/bin/irb:11:in `<main>'

As you can see is possible delete a key/value pair from the Hash @a, as add new keys, change values, eccetera. But you can't point to a new object because is a read only instance variable.

You can use openopt package and its NLP method. It has many dynamic programming algorithms to solve nonlinear algebraic equations consisting:
goldenSection, scipy_fminbound, scipy_bfgs, scipy_cg, scipy_ncg, amsg2p, scipy_lbfgsb, scipy_tnc, bobyqa, ralg, ipopt, scipy_slsqp, scipy_cobyla, lincher, algencan, which you can choose from.
Some of the latter algorithms can solve constrained nonlinear programming problem. So, you can introduce your system of equations to openopt.NLP() with a function like this:

lambda x: x[0] + x[1]**2 - 4, np.exp(x[0]) + x[0]*x[1]

I searched a lot to find out the exact version, because WSUS server shows the wrong version. The best is to get revision from UBR registry KEY.

If you don't need HTTPS and curl is not available on your system you could use fsockopen

This function opens a connection from which you can both read and write like you would do with a normal file handle.

You are setting the response headers after writing the contents of the file to the output stream. This is quite late in the response lifecycle to be setting headers. The correct sequence of operations should be to set the headers first, and then write the contents of the file to the servlet's outputstream.

Therefore, your method should be written as follows (this won't compile as it is a mere representation):

response.setContentType("application/force-download");
response.setContentLength((int)f.length());
        //response.setContentLength(-1);
response.setHeader("Content-Transfer-Encoding", "binary");
response.setHeader("Content-Disposition","attachment; filename=\"" + "xxx\"");//fileName);
...
...
File f= new File(fileName);

InputStream in = new FileInputStream(f);
BufferedInputStream bin = new BufferedInputStream(in);
DataInputStream din = new DataInputStream(bin);

while(din.available() > 0){
    out.print(din.readLine());
    out.print("\n");
}

The reason for the failure is that it is possible for the actual headers sent by the servlet would be different from what you are intending to send. After all, if the servlet container does not know what headers (which appear before the body in the HTTP response), then it may set appropriate headers to ensure that the response is valid; setting the headers after the file has been written is therefore futile and redundant as the container might have already set the headers. You could confirm this by looking at the network traffic using Wireshark or a HTTP debugging proxy like Fiddler or WebScarab.

You may also refer to the Java EE API documentation for ServletResponse.setContentType to understand this behavior:

Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/html;charset=UTF-8. The response's character encoding is only set from the given content type if this method is called before getWriter is called.

This method may be called repeatedly to change content type and character encoding. This method has no effect if called after the response has been committed.

Simply get date and convert

Declare @Date as Date =Getdate()

Select Format(@Date,'dd/MM/yyyy') as [dd/MM/yyyy] // output: 22/10/2020
Select Format(@Date,'dd-MM-yyyy') as [dd-MM-yyyy] // output: 22-10-2020

//string date
Select Format(cast('25/jun/2013' as date),'dd/MM/yyyy') as StringtoDate // output: 25/06/2013

I have set up Volley as a separate Project. That way its not tied to any project and exist independently.

I also have a Nexus server (Internal repo) setup so I can access volley as
compile 'com.mycompany.volley:volley:1.0.4' in any project I need.

Any time I update Volley project, I just need to change the version number in other projects.

I feel very comfortable with this approach.

Update

With ES6, this is possible in exactly the manner you have described; a detailed description can be found in the documentation.

Old answer

Default parameters in JavaScript can be implemented in mainly two ways:

function myfunc(a, b)
{
    // use this if you specifically want to know if b was passed
    if (b === undefined) {
        // b was not passed
    }
    // use this if you know that a truthy value comparison will be enough
    if (b) {
        // b was passed and has truthy value
    } else {
        // b was not passed or has falsy value
    }
    // use this to set b to a default value (using truthy comparison)
    b = b || "default value";
}

The expression b || "default value" evaluates the value AND existence of b and returns the value of "default value" if b either doesn't exist or is falsy.

Alternative declaration:

function myfunc(a)
{
    var b;

    // use this to determine whether b was passed or not
    if (arguments.length == 1) {
        // b was not passed
    } else {
        b = arguments[1]; // take second argument
    }
}

The special "array" arguments is available inside the function; it contains all the arguments, starting from index 0 to N - 1 (where N is the number of arguments passed).

This is typically used to support an unknown number of optional parameters (of the same type); however, stating the expected arguments is preferred!

Further considerations

Although undefined is not writable since ES5, some browsers are known to not enforce this. There are two alternatives you could use if you're worried about this:

b === void 0;
typeof b === 'undefined'; // also works for undeclared variables

Outstream is not closed ... close the stream so that response goes back to test client. Hope this helps.

The difference between pointers and references is quite simple: a pointer can be null, a reference can not.

Examine your API, if it makes sense for null to be able to be returned, possibly to indicate an error, use a pointer, otherwise use a reference. If you do use a pointer, you should add checks to see if it's null (and such checks may slow down your code).

Here it looks like references are more appropriate.

Compile means that you need the JAR for compiling and running the app. For a web application, as an example, the JAR will be placed in the WEB-INF/lib directory.

Provided means that you need the JAR for compiling, but at run time there is already a JAR provided by the environment so you don't need it packaged with your app. For a web app, this means that the JAR file will not be placed into the WEB-INF/lib directory.

For a web app, if the app server already provides the JAR (or its functionality), then use "provided" otherwise use "compile".

Here is the reference.

According to the Interview Cake question, the sequence goes 0,1,1,2,3,5,8,13,21. If this is the case, this solution works and is recursive without the use of arrays.

function fibonacci(n) {
   return n < 1 ? 0
        : n <= 2 ? 1
        : fibonacci(n - 1) + fibonacci(n - 2);
}

console.log(fibonacci(4));

Think of it like this.

   fibonacci(4)   .--------> 2 + 1 = 3
      |          /               |
      '--> fibonacci(3) + fibonacci(2)
            |    ^           
            |    '----------- 2 = 1 + 1 <----------.
1st step -> |                     ^                |
            |                     |                |
            '---->  fibonacci(2) -' + fibonacci(1)-'

Take note, this solution is not very efficient though.

When Postgres.app first starts up, it creates the $USER database, which is the default database for psql when none is specified. The default user is $USER, with no password.

Some scripts (e.g., a database backup created with pgdump on a Linux systsem) and tutorials will assume the superuser has the traditional role name of postgres.

You can make your local install look a bit more traditional and avoid these problems by doing a one time:

/Applications/Postgres.app/Contents/Versions/9.*/bin/createuser -s postgres

which will make those FATAL: role "postgres" does not exist go away.

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

PLEASE FOLLOW THE FLOW CORRECTLY WINDOWS 10x64

1. Powershell run as administrator
2. npm install -g node-gyp
3. npm install --global --production windows-build-tools

This creates a new module/app:

var myApp = angular.module('myApp',[]);

While this accesses an already created module (notice the omission of the second argument):

var myApp = angular.module('myApp');

Since you use the first approach on both scripts you are basically overriding the module you previously created.

On the second script being loaded, use var myApp = angular.module('myApp');.

You need to add a reference to System.Windows.Forms.dll, then use the System.Windows.Forms.FolderBrowserDialog class.

Adding using WinForms = System.Windows.Forms; will be helpful.

public int[] posStatus;       

public UsersInput()    
{    
    //It means postStatus will contain 9 elements from index 0 to 8. 
    this.posStatus = new int[9];   
}

int intUsersInput = 0;   

if (posStatus[intUsersInput-1] == 0) //if i input 9, it should go to 8?    
{    
    posStatus[intUsersInput-1] += 1; //set it to 1    
} 

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

Interesting, I didn't have any references to stdole in my project, but I had a user still receiving the error. I had to add the reference, then change the setting to include. Hopefully that will work.

This is another method to do it as well

package javacore;

import java.util.Scanner;

public class Main_exercise5 {
    public static void main(String[] args) {
        // Local Declaration
        boolean ispoweroftwo = false;
        int n;
        Scanner input = new Scanner (System.in);
        System.out.println("Enter a number");
        n = input.nextInt();
        ispoweroftwo = checkNumber(n);
        System.out.println(ispoweroftwo);
    }
    
    public static boolean checkNumber(int n) {
        // Function declaration
        boolean ispoweroftwo= false;
        // if not divisible by 2, means isnotpoweroftwo
        if(n%2!=0){
            ispoweroftwo=false;
            return ispoweroftwo;
        }
        else {
            for(int power=1; power>0; power=power<<1) {
                if (power==n) {
                    return true;
                }
                else if (power>n) {
                    return false;
                }
            }
        }
        return ispoweroftwo;
    }
}

Sorry this is and old thread but some people would still need this I guess,

Note: I achieved this using Animate.css library for animating the fade.

I used your code and just added .hidden class (using bootstrap's hidden class) but you can still just define .hidden { opacity: 0; }

$(document).ready(function() {

/* Every time the window is scrolled ... */

$(window).scroll( function(){

/* Check the location of each desired element */
$('.hideme').each( function(i){

    var bottom_of_object = $(this).position().top + $(this).outerHeight();
    var bottom_of_window = $(window).scrollTop() + $(window).height();


    /* If the object is completely visible in the window, fade it it */
    if( bottom_of_window > bottom_of_object ){

        $(this).removeClass('hidden');
        $(this).addClass('animated fadeInUp');
    }    else {
            $(this).addClass('hidden');
               }

}); 
}); 
});

Another Note: Applying this to containers might cause it to be glitchy.

It passes control to the next matching route. In the example you give, for instance, you might look up the user in the database if an id was given, and assign it to req.user.

Below, you could have a route like:

app.get('/users', function(req, res) {
  // check for and maybe do something with req.user
});

Since /users/123 will match the route in your example first, that will first check and find user 123; then /users can do something with the result of that.

Route middleware is a more flexible and powerful tool, though, in my opinion, since it doesn't rely on a particular URI scheme or route ordering. I'd be inclined to model the example shown like this, assuming a Users model with an async findOne():

function loadUser(req, res, next) {
  if (req.params.userId) {
    Users.findOne({ id: req.params.userId }, function(err, user) {
      if (err) {
        next(new Error("Couldn't find user: " + err));
        return;
      }

      req.user = user;
      next();
    });
  } else {
    next();
  }
}

// ...

app.get('/user/:userId', loadUser, function(req, res) {
  // do something with req.user
});

app.get('/users/:userId?', loadUser, function(req, res) {
  // if req.user was set, it's because userId was specified (and we found the user).
});

// Pretend there's a "loadItem()" which operates similarly, but with itemId.
app.get('/item/:itemId/addTo/:userId', loadItem, loadUser, function(req, res) {
  req.user.items.append(req.item.name);
});

Being able to control flow like this is pretty handy. You might want to have certain pages only be available to users with an admin flag:

/**
 * Only allows the page to be accessed if the user is an admin.
 * Requires use of `loadUser` middleware.
 */
function requireAdmin(req, res, next) {
  if (!req.user || !req.user.admin) {
    next(new Error("Permission denied."));
    return;
  }

  next();
}

app.get('/top/secret', loadUser, requireAdmin, function(req, res) {
  res.send('blahblahblah');
});

Hope this gave you some inspiration!

Of course! Just use the ALTER TABLE... syntax.

Example

ALTER TABLE YourTable
  ADD Foo INT NULL /*Adds a new int column existing rows will be 
                     given a NULL value for the new column*/

Or

ALTER TABLE YourTable
  ADD Bar INT NOT NULL DEFAULT(0) /*Adds a new int column existing rows will
                                    be given the value zero*/

In SQL Server 2008 the first one is a metadata only change. The second will update all rows.

In SQL Server 2012+ Enterprise edition the second one is a metadata only change too.

Code which disable chrome extensions for ones, who uses DesiredCapabilities to set browser flags :

desired_capabilities['chromeOptions'] = {
    "args": ["--disable-extensions"],
    "extensions": []
}
webdriver.Chrome(desired_capabilities=desired_capabilities)

A better solution for your problem might be the Charts library. It enables you to use the excellent Highcharts javascript library to make beautiful and interactive plots. Highcharts uses the HTML svg tag so all your charts are actually vector images.

Some features:

• Vector plots which you can download in .png, .jpg and .svg formats so you will never run into resolution problems
• Interactive charts (zoom, slide, hover over points, ...)
• Usable in an IPython notebook
• Explore hundreds of data structures at the same time using the asynchronous plotting capabilities.

Disclaimer: I'm the developer of the library

It all depends. Theoretically using a single column with 4 byte data type. You could store 300 000 rows. But there is probably alot of overhead in the database even before you do anything. I read some where that you could have 1.000.000 rows but again, it all depends..

You can also link databases together. Limiting yourself to only disk space.

If you are using Tomcat, check out Psi Probe, which lets you monitor internal and external memory consumption as well as a host of other areas.

Most of the answers above describe what the Y-combinator is but not what it is for.

Fixed point combinators are used to show that lambda calculus is turing complete. This is a very important result in the theory of computation and provides a theoretical foundation for functional programming.

Studying fixed point combinators has also helped me really understand functional programming. I have never found any use for them in actual programming though.

\usepackage[utf8]{inputenc} will not work for a bibliographic entry such as this:

As mentioned in duscusion: WEB-INF is not really a part of class path. If you use a common template such as maven, use src/main/resources or src/test/resources to place the app-context.xml into. Then you can use 'classpath:'.

Place your config file into src/main/resources/app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:app-context.xml")
public class PersonControllerTest {
...
}

or you can make yout test context with different configuration of beans.

Place your config file into src/test/resources/test-app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:test-app-context.xml")
public class PersonControllerTest {
...
}

I was just having the same issue...

To resolve the problem (at least in my case) ensure you have included the lib folder in your bundle classpath:

Manifest-Version: 1.0
... 
Bundle-ClassPath: lib/gson-1.6.jar,
 .
...

Or if you want to include all jar's in the folder:

Bundle-ClassPath: lib/

You will still need to place the jar files on the java build path as shown above. Then your imported jar's should appear in the folder "Referenced Libraries"

Use a CURSOR in PostgreSQL or let the JDBC-driver handle this for you.

LIMIT and OFFSET will get slow when handling large datasets.

In my case, the issue was due to WAMP using a different php.ini for CLI than Apache, so your settings made through the WAMP menu don't apply to CLI. Just modify the CLI php.ini and it works.

Both .done() and .success() are callback functions and they essentially function the same way.

Here's the documentation. The difference is that .success() is deprecated as of jQuery 1.8. You should use .done() instead.

In case you don't want to click the link:

Deprecation Notice

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

Git 1.8.2 features a new option ,--remote, that will enable exactly this behavior. Running

git submodule update --rebase --remote

will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

corrcoef returns the normalised covariance matrix.

The covariance matrix is the matrix

Cov( X, X )    Cov( X, Y )

Cov( Y, X )    Cov( Y, Y )

Normalised, this will yield the matrix:

Corr( X, X )    Corr( X, Y )

Corr( Y, X )    Corr( Y, Y )

correlation1[0, 0 ] is the correlation between Strategy1Returns and itself, which must be 1. You just want correlation1[ 0, 1 ].

pls remove the

Empty lists evaluate to False in boolean contexts (such as if some_list:).

lock_guard and unique_lock are pretty much the same thing; lock_guard is a restricted version with a limited interface.

A lock_guard always holds a lock from its construction to its destruction. A unique_lock can be created without immediately locking, can unlock at any point in its existence, and can transfer ownership of the lock from one instance to another.

So you always use lock_guard, unless you need the capabilities of unique_lock. A condition_variable needs a unique_lock.

For big zip files for deployment, I use quarter hours. No one else on this page had mentioned it before, so I'll put my small script here:

set /a "quarter_hours=%time:~0,2%*4 + %time:~3,2% / 15"
set "zip_file=release_%DATE:~-4%.%DATE:~4,2%.%DATE:~7,2%.%quarter_hours%.zip"

It doesn't zero pad quarter hours from midnight to 5am yet, but it still makes it so you can have a stamped release multiple times a day with few collisions.

Hope that helps.

I don't think this is possible just using CSS (not cross browser at least) but the jQuery plugin ImageMapster will do what you're after. You can outline, colour in or use an alternative image for hover/active states on an image map.

To add on nathan gonzalez answer, please note you need to assign the replaced object after calling replace function since it is not a mutator function:

myString = myString.replace('username1','');
