Just use in OOP manner a class like this:

class div
{
    public int remainder;

    public int quotient(int dividend, int divisor)
    {
        remainder = ...;
        return ...;
    }
}

The function member returns the quotient which most callers are primarily interested in. Additionally it stores the remainder as a data member, which is easily accessible by the caller afterwards.

This way you can have many additional "return values", very useful if you implement database or networking calls, where lots of error messages may be needed but only in case an error occurs.

I entered this solution also in the C++ question that OP is referring to.

In languages like Python, I would usually use a dictionary as it involves less overhead than creating a new class.

However, if I find myself constantly returning the same set of variables, then that probably involves a new class that I'll factor out.

I would suggest doing this in a more functional style :P

function CreateMessageboard(BoardMessages) {
  var htmlMessageboardString = BoardMessages
   .map(function(BoardMessage) {
     return MessageToHTMLString(BoardMessage);
   })
   .join('');
}

Try this

For those who have no errors in Debug mode, but do have the specified error in Release mode (and yet the project runs fine), here is something simple to try:

1. Open the XAML file corresponding to the offending xaml.cs file.
2. Make an edit--any edit, like add a space somewhere
3. Save the file and close it

This method worked for me in VS 2015, and according to other users, also 2017 and 2019

Because equal is a function derived from Object class, this function compares items of the class. if you use it with null it will return false cause cause class content is not null. In addition == compares reference to an object.

Using lodash and not pure javascript

This is actually quite simple using lodash and very easy to add/modify filters.

import _ from 'lodash';

async getUsersWithFilter(filters) {
     const users = yourArrayOfSomethingReally();

    // Some properties of the 'filters' object can be null or undefined, so create a new object without those undefined properties and filter by those who are defined
    const filtersWithoutUndefinedValuesObject = _.omitBy(
      filters,
      _.isNil,
    );

    return _.filter(users, { ...filtersWithoutUndefinedValuesObject });
}

1. The omitBy function checks your filters object and removes any value that is null or undefined (if you take it out, the lodash.filter function wont return any result.

2. The filter function will filter out all the objects who's values don't match with the object you pass as a second argument to the function (which in this case, is your filters object.)

Why use this?

Well, assume you have this object:

const myFiltersObj = {

   name: "Java",
   age: 50

};

If you want to add another filter, just add a new property to the myFilterObj, like this:

const myFiltersObj = {

   name: "Java",
   email: 50,
   country: "HND"

};

Call the getUsersWithFilter function, and it will work just fine. If you skip, let's say the name property in the object, the getUsersWithFilter function will filter by the email and country just fine.

You could also do something like this:

SELECT tb1.* FROM Table tb1 WHERE id = (SELECT MAX(tb2.id) FROM Table tb2);

Its useful when you want to make some joins.

You can do this very easily in Swift using the code:

let string = "hello Swift";
let subString = (string as NSString).containsString("Swift")
if(subString){println("Exist")}

You can't run two SQL statements into one like you are doing.

You can't "execute" a select query.

db is an object and you haven't set it to anything: (e.g. set db = currentdb)

In VBA integer types can hold up to max of 32767 - I would be tempted to use Long.

You might want to be a bit more specific about the date you are inserting:

INSERT INTO Test (Start_Date) VALUES ('#" & format(InDate, "mm/dd/yyyy") & "#' );"

To get the percentage of a number, we need to multiply the desired percentage percent by that number. In practice we will have:

function percentage(percent, total) {
    return ((percent/ 100) * total).toFixed(2)
}

Example of usage:

const percentResult = percentage(10, 100);
// print 10.00

.toFixed() is optional for monetary formats.

Normally updating certifi and/or the certifi cacert.pem file would work. I also had to update my version of python. Vs. 2.7.5 wasn't working because of how it handles SNI requests.

Once you have an up to date pem file you can make your http request using:

requests.get(url, verify='/path/to/cacert.pem')

/** SUBTRACT ARRAYS **/

function subtractarrays(array1, array2){
    var difference = [];
    for( var i = 0; i < array1.length; i++ ) {
        if( $.inArray( array1[i], array2 ) == -1 ) {
                difference.push(array1[i]);
        }
    }
return difference;
}  

You can then call the function anywhere in your code.

var I_like    = ["love", "sex", "food"];
var she_likes = ["love", "food"];

alert( "what I like and she does't like is: " + subtractarrays( I_like, she_likes ) ); //returns "Naughty :P"!

This works in all cases and avoids the problems in the methods above. Hope that helps!

Data can be transferred in SOAP header (JaxWS) by using @WebParam(header = true):

@WebMethod(operationName = "SendRequest", action = "http://abcd.ru/")
@Oneway
public void sendRequest(
    @WebParam(name = "Message", targetNamespace = "http://abcd.ru/", partName = "Message")
    Data message,
    @WebParam(name = "ServiceHeader", targetNamespace = "http://abcd.ru/", header = true, partName = "ServiceHeader")
    Header serviceHeader);

If you want to generate a client with SOAP Headers, you need to use -XadditionalHeaders:

wsimport -keep -Xnocompile -XadditionalHeaders -Xdebug http://12.34.56.78:8080/TestHeaders/somewsdl?wsdl -d /home/evgeny/DEVELOPMENT/JAVA/gen

If don't need @Oneway web service, you can use Holder:

@WebMethod(operationName = "SendRequest", action = "http://abcd.ru/")
public void sendRequest(
    @WebParam(name = "Message", targetNamespace = "http://abcd.ru/", partName = "Message")
    Data message,
    @WebParam(name = "ServiceHeader", targetNamespace = "http://abcd.ru/", header = true, partName = "ServiceHeader")
    Holder<Header> serviceHeader);

Call the pd.DataFrame constructor directly:

df = pd.DataFrame(table, columns=headers)
df

   Heading1  Heading2
0         1         2
1         3         4

Android has build-in Java API. Check out java.util.zip package.

The class ZipInputStream is what you should look into. Read ZipEntry from the ZipInputStream and dump it into filesystem/folder. Check similar example to compress into zip file.

You can try these snippets.

In [16]:mydata = {'x' : [10, 50, 18, 32, 47, 20], 'y' : ['12', '11', 'N/A', '13', '15', 'N/A']}
In [17]:df=pd.DataFrame(mydata)

In [18]:df.y[df.y=="N/A"]=np.nan

Out[19]:df 
    x    y
0  10   12
1  50   11
2  18  NaN
3  32   13
4  47   15
5  20  NaN

I would reach for autopep8 to do this:

$ # see what changes it would make
$ autopep8 path/to/file.py --select=E101,E121 --diff

$ # make these changes
$ autopep8 path/to/file.py --select=E101,E121 --in-place

Note: E101 and E121 are pep8 indentation (I think you can simply pass --select=E1 to fix all indentation related issues - those starting with E1).

You can apply this to your entire project using recursive flag:

$ autopep8 package_dir --recursive --select=E101,E121 --in-place

See also Tool to convert Python code to be PEP8 compliant.

sp_change_users_login is deprecated.

Much easier is:

ALTER USER usr1 WITH LOGIN = login1;

This sentence is a UDP joke, but I'm not sure that you'll get it. The below conversation is a TCP/IP joke:

A: Do you want to hear a TCP/IP joke?
B: Yes, I want to hear a TCP/IP joke.
A: Ok, are you ready to hear a TCP/IP joke?
B: Yes, I'm ready to hear a TCP/IP joke.
A: Well, here is the TCP/IP joke.
A: Did you receive a TCP/IP joke?
B: Yes, I **did** receive a TCP/IP joke.

<input name="submitBnt" type="submit" value="like"/>

name is useful when using $_POST in php and also in javascript as document.getElementByName('submitBnt'). Also you can use name as a CS selector like input[name="submitBnt"]; Hope this helps

A solution in C# would be:

Helper class:

internal class DriverHelper
{

    private IWebDriver Driver { get; set; }
    private WebDriverWait Wait { get; set; }

    public DriverHelper(string driverUrl, int timeoutInSeconds)
    {
        Driver = new ChromeDriver();
        Driver.Url = driverUrl;
        Wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(timeoutInSeconds));
    }

    internal bool ClickElement(string cssSelector)
    {
        //Find the element
        IWebElement element = Wait.Until(d=>ExpectedConditions.ElementIsVisible(By.CssSelector(cssSelector)))(Driver);
        return Wait.Until(c => ClickElement(element, cssSelector));
    }

    private bool ClickElement(IWebElement element, string cssSelector)
    {
        try
        {
            //Check if element is still included in the dom
            //If the element has changed a the OpenQA.Selenium.StaleElementReferenceException is thrown.
            bool isDisplayed = element.Displayed;

            element.Click();
            return true;
        }
        catch (StaleElementReferenceException)
        {
            //wait until the element is visible again
            element = Wait.Until(d => ExpectedConditions.ElementIsVisible(By.CssSelector(cssSelector)))(Driver);
            return ClickElement(element, cssSelector);
        }
        catch (Exception)
        {
            return false;
        }
    }
}

Invocation:

        DriverHelper driverHelper = new DriverHelper("http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp", 10);
        driverHelper.ClickElement("input[value='csharp']:first-child");

Similarly can be used for Java.

<!doctype html>_x000D_

    lfckv = document.getElementsByClassName("lifecheck");_x000D_
    if (true === lfckv[0].checked) {_x000D_
      alert('the checkbox is checked');_x000D_

so after you can add event in javascript to have dynamical event affected with the checkbox .

If you're using Eclipse, make sure you use debug and not run. Make sure you are in the debug perspective (top right) You may have to hit 'Resume' (F8) a few times for the log to print. The crash log will be in the Logcat window at the bottom- double click for fullscreen and make sure you scroll to the bottom. You'll see red text for errors, the crash trace will be something like

I just had this error when I opened a (quite) old project, created in Xcode 4~ish, in Xcode 6.4. While the linked Frameworks were visible in the Project sidebar, I overlooked that there were no linked libraries in the Target Build Phases tab. Once I fixed that, it compiled fine.

Just to be complete, I'll build build off of Robocide and point out that typeid can be used alone without using name():

#include <typeinfo>
#include <iostream>

using namespace std;

class A {
public:
    virtual ~A() = default; // We're not polymorphic unless we
                            // have a virtual function.
};
class B : public A { } ;
class C : public A { } ;

int
main(int argc, char* argv[])
{
    B b;
    A& a = b;

    cout << "a is B: " << boolalpha << (typeid(a) == typeid(B)) << endl;
    cout << "a is C: " << boolalpha << (typeid(a) == typeid(C)) << endl;
    cout << "b is B: " << boolalpha << (typeid(b) == typeid(B)) << endl;
    cout << "b is A: " << boolalpha << (typeid(b) == typeid(A)) << endl;
    cout << "b is C: " << boolalpha << (typeid(b) == typeid(C)) << endl;
}

Output:

a is B: true
a is C: false
b is B: true
b is A: false
b is C: false

You can use assign_attributes or attributes= (they're the same)

Update methods cheat sheet (for Rails 6):

• update = assign_attributes + save
• attributes= = alias of assign_attributes
• update_attributes = deprecated, alias of update

You can do something like

MyClass[] arr = myList.toArray(new MyClass[myList.size()]);

Here's the complete solution if you want to implement the wifi hotspot feature programmatically in your android app.

SOLUTION FOR API < 26:

For devices < API 26. There is no public API by Android for this purpose. So, in order to work with those APIs you've to access private APIs through reflection. It is not recommended but if you've no other options left, then here's a trick.

First of all, you need to have this permission in your manifest,

  <uses-permission  
  android:name="android.permission.WRITE_SETTINGS"  
  tools:ignore="ProtectedPermissions"/>

  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
  <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
  <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Here's how you can ask it on run-time:

 private boolean showWritePermissionSettings() {    
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M  
    && Build.VERSION.SDK_INT < Build.VERSION_CODES.O) { 
  if (!Settings.System.canWrite(this)) {    
    Log.v("DANG", " " + !Settings.System.canWrite(this));   
    Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS); 
    intent.setData(Uri.parse("package:" + this.getPackageName()));  
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
    this.startActivity(intent); 
    return false;   
  } 
}   
return true; //Permission already given 
}

You can then access the setWifiEnabled method through reflection. This returns true if the action you asked for is being process correctly i.e. enabling/disabling hotspot.

     public boolean setWifiEnabled(WifiConfiguration wifiConfig, boolean enabled) { 
 WifiManager wifiManager;
try {   
  if (enabled) { //disables wifi hotspot if it's already enabled    
    wifiManager.setWifiEnabled(false);  
  } 

   Method method = wifiManager.getClass()   
      .getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);   
  return (Boolean) method.invoke(wifiManager, wifiConfig, enabled); 
} catch (Exception e) { 
  Log.e(this.getClass().toString(), "", e); 
  return false; 
}   
}

You can also get the wificonfiguration of your hotspot through reflection. I've answered that method for this question on StackOverflow.

P.S: If you don't want to turn on hotspot programmatically, you can start this intent and open the wifi settings screen for user to turn it on manually.

SOLUTION FOR API >= 26:

Finally, android released an official API for versions >= Oreo. You can just use the public exposed API by android i.e. startLocalOnlyHotspot

It turns on a local hotspot without internet access. Which thus can be used to host a server or transfer files.

It requires Manifest.permission.CHANGE_WIFI_STATE and ACCESS_FINE_LOCATION permissions.

Here's a simple example of how you can turn on hotspot using this API.

private WifiManager wifiManager;
WifiConfiguration currentConfig;
WifiManager.LocalOnlyHotspotReservation hotspotReservation;

The method to turn on hotspot:

@RequiresApi(api = Build.VERSION_CODES.O)
public void turnOnHotspot() {

      wifiManager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {

        @Override
        public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
          super.onStarted(reservation);
          hotspotReservation = reservation;
          currentConfig = hotspotReservation.getWifiConfiguration();

          Log.v("DANG", "THE PASSWORD IS: "
              + currentConfig.preSharedKey
              + " \n SSID is : "
              + currentConfig.SSID);

          hotspotDetailsDialog();

        }

        @Override
        public void onStopped() {
          super.onStopped();
          Log.v("DANG", "Local Hotspot Stopped");
        }

        @Override
        public void onFailed(int reason) {
          super.onFailed(reason);
          Log.v("DANG", "Local Hotspot failed to start");
        }
      }, new Handler());
    }
`

Here's how you can get details of the locally created hotspot

private void hotspotDetaisDialog()
{

    Log.v(TAG, context.getString(R.string.hotspot_details_message) + "\n" + context.getString(
              R.string.hotspot_ssid_label) + " " + currentConfig.SSID + "\n" + context.getString(
              R.string.hotspot_pass_label) + " " + currentConfig.preSharedKey);

}

If it throws, a security exception even after giving the required permissions then you should try enabling your location using GPS. Here's the solution.

Recently, I've developed a demo app called Spotserve. That turns on wifi hotspot for all devices with API>=15 and hosts a demo server on that hotspot. You can check that for more details. Hope this helps!

This is because of implicit conversion. The variables b, c, d are of float type. But the / operator sees two integers it has to divide and hence returns an integer in the result which gets implicitly converted to a float by the addition of a decimal point. If you want float divisions, try making the two operands to the / floats. Like follows.

#include <stdio.h>

int main() {
    int a;
    float b, c, d;
    a = 750;
    b = a / 350.0f;
    c = 750;
    d = c / 350;
    printf("%.2f %.2f", b, d);
    // output: 2.14 2.14
    return 0;
}

Say you're using CRTP to provide an "interface" for a set of child templates; and both the parent and the child are parametric in other template argument(s):

template <typename DERIVED, typename VALUE> class interface {
    void do_something(VALUE v) {
        static_cast<DERIVED*>(this)->do_something(v);
    }
};

template <typename VALUE> class derived : public interface<derived, VALUE> {
    void do_something(VALUE v) { ... }
};

typedef interface<derived<int>, int> derived_t;

Note the duplication of 'int', which is actually the same type parameter specified to both templates. You can use a template template for DERIVED to avoid this duplication:

template <template <typename> class DERIVED, typename VALUE> class interface {
    void do_something(VALUE v) {
        static_cast<DERIVED<VALUE>*>(this)->do_something(v);
    }
};

template <typename VALUE> class derived : public interface<derived, VALUE> {
    void do_something(VALUE v) { ... }
};

typedef interface<derived, int> derived_t;

Note that you are eliminating directly providing the other template parameter(s) to the derived template; the "interface" still receives them.

This also lets you build up typedefs in the "interface" that depend on the type parameters, which will be accessible from the derived template.

The above typedef doesn't work because you can't typedef to an unspecified template. This works, however (and C++11 has native support for template typedefs):

template <typename VALUE>
struct derived_interface_type {
    typedef typename interface<derived, VALUE> type;
};

typedef typename derived_interface_type<int>::type derived_t;

You need one derived_interface_type for each instantiation of the derived template unfortunately, unless there's another trick I haven't learned yet.

The page you linked states

If an explicit array size is specified, but an shorter initiliazation list is specified, the unspecified elements are set to zero.

Speed issue: Any differences would be negligible for arrays this small. If you work with large arrays and speed is much more important than size, you can have a const array of the default values (initialized at compile time) and then memcpy them to the modifiable array.

I faced with the same issue when I tried to send bitmap via Intent and at the same time when it happens I folded the application.

How it described in this article enter link description here it happens when an Activity is in the process of stopping, that means that the Activity was trying to send its saved state Bundles to the system OS for safe keeping for restoration later (after a config change or process death) but that one or more of the Bundles it sent were too large.

I solved it via hack by overriding onSaveInstanceState in my Activity:

@Override
protected void onSaveInstanceState(Bundle outState) {
    // super.onSaveInstanceState(outState);
}

and comment call super. It is a dirty hack but it is working perfectly. Bitmap was successfully sent without crashes. Hope this will help someone.

Maybe using cookielib.CookieJar can help you. For instance when posting to a page containing a form:

import urllib2
import urllib
from cookielib import CookieJar

cj = CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
# input-type values from the html form
formdata = { "username" : username, "password": password, "form-id" : "1234" }
data_encoded = urllib.urlencode(formdata)
response = opener.open("https://page.com/login.php", data_encoded)
content = response.read()

EDIT:

After Piotr's comment I'll elaborate a bit. From the docs:

The CookieJar class stores HTTP cookies. It extracts cookies from HTTP requests, and returns them in HTTP responses. CookieJar instances automatically expire contained cookies when necessary. Subclasses are also responsible for storing and retrieving cookies from a file or database.

So whatever requests you make with your CookieJar instance, all cookies will be handled automagically. Kinda like your browser does :)

I can only speak from my own experience and my 99% use-case for cookies is to receive a cookie and then need to send it with all subsequent requests in that session. The code above handles just that, and it does so transparently.

Good question.

• @@IDENTITY: returns the last identity value generated on your SQL connection (SPID). Most of the time it will be what you want, but sometimes it isn't (like when a trigger is fired in response to an INSERT, and the trigger executes another INSERT statement).

• SCOPE_IDENTITY(): returns the last identity value generated in the current scope (i.e. stored procedure, trigger, function, etc).

• IDENT_CURRENT(): returns the last identity value for a specific table. Don't use this to get the identity value from an INSERT, it's subject to race conditions (i.e. multiple connections inserting rows on the same table).

• IDENTITY(): used when declaring a column in a table as an identity column.

For more reference, see: http://msdn.microsoft.com/en-us/library/ms187342.aspx.

To summarize: if you are inserting rows, and you want to know the value of the identity column for the row you just inserted, always use SCOPE_IDENTITY().

A temporary table can have 3 kinds, the # is the most used. This is a temp table that only exists in the current session. An equivalent of this is @, a declared table variable. This has a little less "functions" (like indexes etc) and is also only used for the current session. The ## is one that is the same as the #, however, the scope is wider, so you can use it within the same session, within other stored procedures.

You can create a temp table in various ways:

declare @table table (id int)
create table #table (id int)
create table ##table (id int)
select * into #table from xyz

i want to mention some important point to bare in mind while implementing class binding.

    [ngClass] = "{
    'badge-secondary': somevariable  === value1,
    'badge-danger': somevariable  === value1,
    'badge-warning': somevariable  === value1,
    'badge-warning': somevariable  === value1,
    'badge-success': somevariable  === value1 }" 

class here is not binding correctly because one condition is to be met, whereas you have two identical classes 'badge-warning' that may have two different condition. To correct this

 [ngClass] = "{
    'badge-secondary': somevariable === value1,
    'badge-danger': somevariable  === value1,
    'badge-warning': somevariable  === value1 || somevariable  === value1, 
    'badge-success': somevariable  === value1 }" 

There is a case I often use. I have a IdUtil class with static methods to work with objects implementing a very simple Identifiable interface:

public interface Identifiable<K> {
    K getId();
}


public abstract class IdUtil {

    public static <T extends Enum<T> & Identifiable<S>, S> T get(Class<T> type, S id) {
        for (T t : type.getEnumConstants()) {
            if (Util.equals(t.getId(), id)) {
                return t;
            }
        }
        return null;
    }

    public static <T extends Enum<T> & Identifiable<S>, S extends Comparable<? super S>> List<T> getLower(T en) {
        List<T> list = new ArrayList<>();
        for (T t : en.getDeclaringClass().getEnumConstants()) {
             if (t.getId().compareTo(en.getId()) < 0) {
                 list.add(t);
            }
        }
        return list;
    }
}

If I create an Identifiable enum:

    public enum MyEnum implements Identifiable<Integer> {

        FIRST(1), SECOND(2);

        private int id;

        private MyEnum(int id) {
            this.id = id;
        }

        public Integer getId() {
            return id;
        }

    }

Then I can get it by its id this way:

MyEnum e = IdUtil.get(MyEnum.class, 1);

I was getting a similar problem in Eclipse STS when trying to run a Maven install on a project. I had changed some versions in the dependencies of my pom.xml file for that project and the projects that those dependencies pointed to. I solved it by running a Maven install on all the projects I changed and then running install on the original one again.

As Kintaro already says, person is a method (because of def) and always returns a new Person instance. As you found out it would work if you change the method to a var or val:

val person = new Person("Kumar",12)

Another possibility would be:

def person = new Person("Kumar",12)
val p = person
p.age=20
println(p.age)

However, person.age=20 in your code is allowed, as you get back a Person instance from the person method, and on this instance you are allowed to change the value of a var. The problem is, that after that line you have no more reference to that instance (as every call to person will produce a new instance).

This is nothing special, you would have exactly the same behavior in Java:

class Person{ 
   public int age; 
   private String name;
   public Person(String name; int age) {
      this.name = name;  
      this.age = age;
   }
   public String name(){ return name; }
}

public Person person() { 
  return new Person("Kumar", 12); 
}

person().age = 20;
System.out.println(person().age); //--> 12

First of all, you need not do var r = this; as this in if statement refers to the context of the callback itself which since you are using arrow function refers to the React component context.

According to the docs:

history objects typically have the following properties and methods:

• length - (number) The number of entries in the history stack
• action - (string) The current action (PUSH, REPLACE, or POP)

• location - (object) The current location. May have the following properties:

  • pathname - (string) The path of the URL
  • search - (string) The URL query string
  • hash - (string) The URL hash fragment
  • state - (string) location-specific state that was provided to e.g. push(path, state) when this location was pushed onto the stack. Only available in browser and memory history.
• push(path, [state]) - (function) Pushes a new entry onto the history stack
• replace(path, [state]) - (function) Replaces the current entry on the history stack
• go(n) - (function) Moves the pointer in the history stack by n entries
• goBack() - (function) Equivalent to go(-1)
• goForward() - (function) Equivalent to go(1)
• block(prompt) - (function) Prevents navigation

So while navigating you can pass props to the history object like

this.props.history.push({
  pathname: '/template',
  search: '?query=abc',
  state: { detail: response.data }
})

or similarly for the Link component or the Redirect component

<Link to={{
      pathname: '/template',
      search: '?query=abc',
      state: { detail: response.data }
    }}> My Link </Link>

and then in the component which is rendered with /template route, you can access the props passed like

this.props.location.state.detail

Also keep in mind that, when using history or location objects from props you need to connect the component with withRouter.

As per the Docs:

withRouter

You can get access to the history object’s properties and the closest <Route>'s match via the withRouter higher-order component. withRouter will re-render its component every time the route changes with the same props as <Route> render props: { match, location, history }.

The strategy from Wikipedia for playing a perfect game (win or tie every time) seems like straightforward pseudo-code:

Quote from Wikipedia (Tic Tac Toe#Strategy)

A player can play a perfect game of Tic-tac-toe (to win or, at least, draw) if they choose the first available move from the following list, each turn, as used in Newell and Simon's 1972 tic-tac-toe program.[6]

1. Win: If you have two in a row, play the third to get three in a row.

2. Block: If the opponent has two in a row, play the third to block them.

3. Fork: Create an opportunity where you can win in two ways.

4. Block Opponent's Fork:

   Option 1: Create two in a row to force the opponent into defending, as long as it doesn't result in them creating a fork or winning. For example, if "X" has a corner, "O" has the center, and "X" has the opposite corner as well, "O" must not play a corner in order to win. (Playing a corner in this scenario creates a fork for "X" to win.)

   Option 2: If there is a configuration where the opponent can fork, block that fork.

5. Center: Play the center.

6. Opposite Corner: If the opponent is in the corner, play the opposite corner.

7. Empty Corner: Play an empty corner.

8. Empty Side: Play an empty side.

Recognizing what a "fork" situation looks like could be done in a brute-force manner as suggested.

Note: A "perfect" opponent is a nice exercise but ultimately not worth 'playing' against. You could, however, alter the priorities above to give characteristic weaknesses to opponent personalities.

If #restart is an inline element (eg <span>, <em> etc) then you can turn it into a block element using:

#restart { display: block; }

This will have the effect of ensuring a line break both before and after the element.

There is not a way to have CSS insert something that acts like a line break only before an element and not after. You could perhaps cause a line-break before as a side-effect of other changes, for example float: left, or clear: left after a floated element, or even something crazy like #restart:before { content: 'a load of non-breaking spaces'; } but this probably isn't a good idea in the general case.

Doing what the original question asked—to get the old Twitter's Nav Bar look, blue background with white text—is very easy to do just using the Interface Builder in Xcode.

• Using the Document Outline, select your Navigation Bar.
• In the Attributes Inspector, in the Navigation Bar group, change the Style from Default to Black. This changes the background colour of the Navigation and Status bars to black, and their text to white. So the battery and other icons and text in the status bar will look white when the app is running.
• In the same Navigation Bar group, change the Bar Tint to the colour of your liking.
• If you have Bar Button items in your Navigation Bar, those will still show their text in the default blue colour, so in the Attributes Inspector, View group, change the Tint to White Colour.

That should get you what you want. Here is a screenshot that would make it easier to see where to make the changes.

Note that changing only the Bar Tint doesn't change the text colour in the Navigation Bar or the Status Bar. The Style also needs to be changed.

These answers are a bit too long and focused on interactive use. The important differences for scripting are:

• .cmd prevents inadvertent execution on non-NT systems.
• .cmd enables built-in commands to change Errorlevel to 0 on success.

Not that exciting, eh?

There used to be a number of additional features enabled in .cmd files, called Command Extensions. However, they are now enabled by default for both .bat and .cmd files under Windows 2000 and later.

Bottom line: in 2012 and beyond, I recommend using .cmd exclusively.

It indicates that the servlet won't be started until a request tries to access it.

If load-on-startup is greater than or equal to zero then when the container starts it will start that servlet in ascending order of the load on startup value you put there (ie 0, 1 then 2 then 5 then 10 and so on).

More recent pandas versions have the pd.DataFrame.multiply function.

iOS 14

For me, view.window is null on iOS 14.

extension UIViewController {
    var topBarHeight: CGFloat {
        var top = self.navigationController?.navigationBar.frame.height ?? 0.0
        if #available(iOS 13.0, *) {
            top += UIApplication.shared.windows.first?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
        } else {
            top += UIApplication.shared.statusBarFrame.height
        }
        return top
    }
}

Put sleep. It will work. I have tried. The reason is that the page wasn't loaded yet. Check this question to know how to wait for load - Wait for page load in Selenium

To pull from the default branch, new repositories should use the command:

git pull origin main

Github changed naming convention of default branch from master to main in 2020. https://github.com/github/renaming

String.Format also works in Razor:

String.Format("{0} - {1}", Model.address, Model.city)

to stop a docker process and release the ports, first use ctrl-c to leave the exit the container then use docker ps to find the list of running containers. Then you can use the docker container stop to stop that process and release its ports. The container name you can find from the docker ps command which gives the name in the name column. Hope this solves your queries....

To expand on John's answer you can also use the Dockerfile CMD command as following (in case you want it to self start without additional args)

CMD ["nginx", "-g", "daemon off;"]

The best way is to use the ng-options directive on the select element.

Controller

function Ctrl($scope) {
  // sort options
  $scope.products = [{
    value: 'prod_1',
    label: 'Product 1'
  }, {
    value: 'prod_2',
    label: 'Product 2'
  }];   
}

HTML

<select ng-model="selected_product" 
        ng-options="product as product.label for product in products">           
</select>

This will bind the selected product object to the ng-model property - selected_product. After that you can use this:

<p>Ordered by: {{selected_product.label}}</p>

This line:

eventCustom.DateTimeEnd = dateTimeEndResult = true ? (DateTime?)null : dateTimeEndResult;

is same as:

eventCustom.DateTimeEnd = dateTimeEndResult = (true ? (DateTime?)null : dateTimeEndResult);

because the conditional operator ? has a higher precedence than the assignment operator =. That's why you always get null for eventCustom.DateTimeEnd. (MSDN Ref)

Just make sure semver is installed: npm install -g semver

The agg function will do this for you. Pass the columns and function as a dict with column, output:

df.groupby(['Country', 'Item_Code']).agg({'Y1961': np.sum, 'Y1962': [np.sum, np.mean]})  # Added example for two output columns from a single input column

This will display only the group by columns, and the specified aggregate columns. In this example I included two agg functions applied to 'Y1962'.

To get exactly what you hoped to see, included the other columns in the group by, and apply sums to the Y variables in the frame:

df.groupby(['Code', 'Country', 'Item_Code', 'Item', 'Ele_Code', 'Unit']).agg({'Y1961': np.sum, 'Y1962': np.sum, 'Y1963': np.sum})

You can also "prepend" the environment variable setting by using 'environment' command:

run.doFirst { environment 'SPARK_LOCAL_IP', 'localhost' }

In Java doc of Var-Args it is quite clear the usage of var args:

http://docs.oracle.com/javase/1.5.0/docs/guide/language/varargs.html

about usage it says:

"So when should you use varargs? As a client, you should take advantage of them whenever the API offers them. Important uses in core APIs include reflection, message formatting, and the new printf facility. As an API designer, you should use them sparingly, only when the benefit is truly compelling. Generally speaking, you should not overload a varargs method, or it will be difficult for programmers to figure out which overloading gets called. "

private ViewPager viewPager;
viewPager = (ViewPager) findViewById(R.id.pager);
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        @Override
        public void onPageSelected(int position) {
            // on changing the page
            // make respected tab selected
            actionBar.setSelectedNavigationItem(position);
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {

An alternative to fsolve is root:

import numpy as np
from scipy.optimize import root    

def your_funcs(X):

    x, y = X
    # all RHS have to be 0
    f = [x + y**2 - 4,
         np.exp(x) + x * y - 3]

    return f

sol = root(your_funcs, [1.0, 1.0])
print(sol.x)

This will print

[0.62034452 1.83838393]

If you then check

print(your_funcs(sol.x))

you obtain

[4.4508396968012676e-11, -1.0512035686360832e-11]

confirming that the solution is correct.

You could move the div when the table is drawn using the fnDrawCallback function.

    $("#myTable").dataTable({
    "fnDrawCallback": function (oSettings) {
        $(".dataTables_filter").each(function () {
            $(this).appendTo($(this).parent().siblings(".panel-body"));
        });
    }
});

As posted above by blackjar, the below lines worked for me

pip --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org install xxx

You need to give all three --trusted-host options. I was trying with only the first one after looking at the answers but it didn't work for me like that.

To make this easier to use, I wrote a generic extension:

public static string ToDescription<TEnum>(this TEnum EnumValue) where TEnum : struct
{
    return Enumerations.GetEnumDescription((Enum)(object)((TEnum)EnumValue));
}

now I can write:

        MyEnum my = MyEnum.HereIsAnother;
        string description = my.ToDescription();
        System.Diagnostics.Debug.Print(description);

Note: replace "Enumerations" above with your class name

It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)

Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.

The xcodebuild tool can build and export archive products with the -exportArchive flag (as of Xcode 5). The export step was previously only possible via the Xcode Organizer UI.

First archive your app:

xcodebuild -scheme <scheme name> archive

Given $ARCHIVE_PATH (the path to the .xcarchive file), export the app from the archive with one of the following:

iOS .ipa file:

xcodebuild -exportArchive -exportFormat ipa -archivePath "$ARCHIVE_PATH" -exportPath "myApp.ipa" -exportProvisioningProfile "My App Provisioning profile"

Mac .app file:

xcodebuild -exportArchive -exportFormat app -archivePath "$ARCHIVE_PATH" -exportPath "myApp.app" -exportSigningIdentity "Developer ID Application: My Software Company"

In both commands the -exportProvisioningProfile and -exportSigningIdentity arguments are optional. man xcodebuild for details on the semantics. In these examples, the provisioning profile for the iOS build specified an AdHoc distribution provisioning profile, and the signing identity for the Mac app specified a Developer ID for export as a 3rd party application (i.e. not distributed via the Mac App Store).

With Java 8 lambda expression you can do something like

cats.stream()
    .filter( c -> c.getAge() == 3 && c.getFavoriteFood() == WHISKAS )
    .collect(Collectors.toList());

Conceptually the same as the Guava Predicate approach, but it looks much cleaner with lambda

Probably not a valid answer for OP but worth to note for people with similar need. :)

Your error message is pretty explicit about what is going wrong:

laravel/framework v5.2.9 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

Do you have mbstring installed on your server and is it enabled?

You can install mbstring as part of the libapache2-mod-php5 package:

sudo apt-get install libapache2-mod-php5

Or standalone with:

sudo apt-get install php-mbstring

Installing it will also enable it, however you can also enable it by editing your php.ini file and remove the ; that is commenting it out if it is already installed.

If this is on your local machine, then follow the appropriate steps to install this on your environment.

Just do a simple .keys()

>>> dct = {
...     "1": "a", 
...     "3": "b", 
...     "8": {
...         "12": "c", 
...         "25": "d"
...     }
... }
>>> 
>>> dct.keys()
['1', '8', '3']
>>> for key in dct.keys(): print key
...
1
8
3
>>>

If you need a sorted list:

keylist = dct.keys()
keylist.sort()

You can optimize the query using Dense_rank() function.

for Example :

select distinct salary from ( select salary ,dense_rank() over (order by salary desc) ranking from Employee ) where ranking = 6

Note: ranking 6 is the number of nth order.

Note that on OS X you might get strange errors like "invalid command code" or other strange errors when running this command. To fix this issue try

sed -i '' -e "s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g" <file>

This is because on the OSX version of sed, the -i option expects an extension argument so your command is actually parsed as the extension argument and the file path is interpreted as the command code. Source: https://stackoverflow.com/a/19457213

I think the beginning to the resolution to this issue is the fact that the use of the for loop or any other function or action can not be done in the class definition but needs to be included in a method/constructor/block definition inside of a class.

If using AngularJS 1.2 you can use 'track by' to tell Angular how to compare objects.

    ng-options="choice.Name for choice in Choice.Options track by choice.ID">

A nice Java 7+ answer from Benoit Blanchon can be found here:

With Java 7, you can use Files.createDirectories().

For instance:

Files.createDirectories(Paths.get("/path/to/directory"));

For me to get rid of this error, I needed to delete the Pods directory and delete the Podfile.lock file.

I got the same error.

On my view I was overriding get_form_kwargs() like this:

def get_form_kwargs(self):
    kwargs = super(UserAccountView, self).get_form_kwargs()
    kwargs.update({'user': self.request.user})
    return kwargs

But on my form I failed to override the init() method. Once I did it. Problem solved

class UserAccountForm(forms.Form):
    first_name = forms.CharField(label='Your first name', max_length=30)
    last_name = forms.CharField(label='Your last name', max_length=30)
    email = forms.EmailField(max_length=75)

    def __init__(self, *args, **kwargs):
        user = kwargs.pop('user')
        super(UserAccountForm, self).__init__(*args, **kwargs)

Use UNION:

SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks
UNION
SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks

Or UNION ALL if you want duplicates:

SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks
UNION ALL
SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks

if you dont have a database, you will have to hardcode the login details in your code, or read it from a flat file on disk.

setRetaininstance is only useful when your activity is destroyed and recreated due to a configuration change because the instances are saved during a call to onRetainNonConfigurationInstance. That is, if you rotate the device, the retained fragments will remain there(they're not destroyed and recreated.) but when the runtime kills the activity to reclaim resources, nothing is left. When you press back button and exit the activity, everything is destroyed.

Usually I use this function to saved orientation changing Time.Say I have download a bunch of Bitmaps from server and each one is 1MB, when the user accidentally rotate his device, I certainly don't want to do all the download work again.So I create a Fragment holding my bitmaps and add it to the manager and call setRetainInstance,all the Bitmaps are still there even if the screen orientation changes.

There is solution for you :)

You must run your script after window loaded

if you use jQuery, you can use simple way:

<div id="fb-root"></div>

Either run in SQL:

ALTER TABLE tableName
  ADD PRIMARY KEY (id)           ---or Drugid, whichever you want it to be PK

or use the PHPMyAdmin interface (Table Structure)

You do say that the comparison is for sorting purposes. Then I suggest instead:

"a".localeCompare("b");

It returns -1 since "a" < "b", 1 or 0 otherwise, like you need for Array.prototype.sort()

Keep in mind that sorting is locale dependent. E.g. in German, ä is a variant of a, so "ä".localeCompare("b", "de-DE") returns -1. In Swedish, ä is one of the last letters in the alphabet, so "ä".localeCompare("b", "se-SE") returns 1.

Without the second parameter to localeCompare, the browser's locale is used. Which in my experience is never what I want, because then it'll sort differently than the server, which has a fixed locale for all users.

more.exe exists on Windows, ports of less are easily found (and the PowerShell Community Extensions, PSCX, includes one).

PowerShell doesn't really provide any alternative to separate programs for either, but for structured data Out-Grid can be helpful.

Head and Tail can both be emulated with Select-Object using the -First and -Last parameters respectively.

Sed functions are all available but structured rather differently. The filtering options are available in Where-Object (or via Foreach-Object and some state for ranges). Other, transforming, operations can be done with Select-Object and Foreach-Object.

However as PowerShell passes (.NET) objects – with all their typed structure, eg. dates remain DateTime instances – rather than just strings, which each command needs to parse itself, much of sed and other such programs are redundant.

How about using direct axios API?

axios({
  method: 'post',
  url: baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan,
  headers: {}, 
  data: {
    foo: 'bar', // This is the body part
  }
});

There are (at least) two types of package dependencies you can indicate in your package.json files:

1. Those packages that are required in order to use your module are listed under the "dependencies" property. Using npm you can add those dependencies to your package.json file this way:

   npm install --save packageName
   

2. Those packages required in order to help develop your module are listed under the "devDependencies" property. These packages are not necessary for others to use the module, but if they want to help develop the module, these packages will be needed. Using npm you can add those devDependencies to your package.json file this way:

   npm install --save-dev packageName
   

Bash is a Command Line Interface that was created over twenty-seven years ago by Brian Fox as a free software replacement for the Bourne Shell. A shell is a specific kind of Command Line Interface. Bash is "open source" which means that anyone can read the code and suggest changes. Since its beginning, it has been supported by a large community of engineers who have worked to make it an incredible tool. Bash is the default shell for Linux and Mac. For these reasons, Bash is the most used and widely distributed shell.

Windows has a different Command Line Interface, called Command Prompt. While this has many of the same features as Bash, Bash is much more popular. Because of the strength of the open source community and the tools they provide, mastering Bash is a better investment than mastering Command Prompt.

To use Bash on a Windows computer, we need to download and install a program called Git Bash. Git Bash (Is the Bash for windows) allows us to easily access Bash as well as another tool called Git, inside the Windows environment.

Try as follows the return must be d, not d.data

 ajax: {
      "url": "xx/xxx/xxx",
      "type": "GET",
      "error": function (e) {
      },
      "dataSrc": function (d) {
         return d
      }
      },

The way you can exclude a destination directory while using the /mir is by making sure the destination directory also exists on the source. I went into my source drive and created blank directories with the same name as on the destination, and then added that directory name to the /xd. It successfully mirrored everything while excluding the directory on the source, thereby leaving the directory on the destination intact.

There is a simpler way in Android

 DateFormat.getInstance().format(currentTimeMillis);

Moreover, Date is deprecated, so use DateFormat class.

   DateFormat.getDateInstance().format(new Date(0));  
   DateFormat.getDateTimeInstance().format(new Date(0));  
   DateFormat.getTimeInstance().format(new Date(0));  

The above three lines will give:

Dec 31, 1969  
Dec 31, 1969 4:00:00 PM  
4:00:00 PM  12:00:00 AM

/* Current time */
 select now(); 

/* Epoch from current time;
   Epoch is number of seconds since 1970-01-01 00:00:00+00 */
 select extract(epoch from now()); 

/* Get back time from epoch */
 -- Option 1 - use to_timestamp function
 select to_timestamp( extract(epoch from now()));
 -- Option 2 - add seconds to 'epoch'
 select timestamp with time zone 'epoch' 
         + extract(epoch from now()) * interval '1 second';

/* Cast timestamp to date */
 -- Based on Option 1
 select to_timestamp(extract(epoch from now()))::date;
 -- Based on Option 2
 select (timestamp with time zone 'epoch' 
          + extract(epoch from now()) * interval '1 second')::date; 

 /* For column epoch_ms */
 select to_timestamp(extract(epoch epoch_ms))::date;

What about constructing the element using jQuery? e.g.

$("<div></div>")

creates a new div element, ready to be added to the page. Can be shortened further to

$("<div>")

then you can chain on commands that you need, set up event handlers and append it to the DOM. For example

$('<div id="myid">Div Content</div>')
    .bind('click', function(e) { /* event handler here */ })
    .appendTo('#myOtherDiv');

You can take a look at stagemonitor. It is a open source java (web) application performance monitor. It captures response time metrics, JVM metrics, request details (including a call stack captured by the request profiler) and more. The overhead is very low.

Optionally, you can use the great timeseries database graphite with it to store a long history of datapoints that you can look at with fancy dashboards.

Example:

Take a look at the project website to see screenshots, feature descriptions and documentation.

Note: I am the developer of stagemonitor

On the topic of cleaning up remote branches

git branch -r | xargs -t -n 1 git branch -r --contains

This lists each remote branch followed by which remote branches their latest SHAs are within.

This is useful to discern which remote branches have been merged but not deleted, and which haven't been merged and thus are decaying.

If you're using 'tig' (its like gitk but terminal based) then you can

tig origin/feature/someones-decaying-feature

to see a branch's commit history without having to git checkout

Almost 5 years later, I think my answer can reduce a little bit the hard work of many people.

Update an element in the DOM with the HTML from the one from the ajax call can be achieved that way

$('#submitform').click(function() {
     $.ajax({
     url: "getinfo.asp",
     data: {
         txtsearch: $('#appendedInputButton').val()
     },
     type: "GET",
     dataType : "html",
     success: function (data){
         $('#showresults').html($('#showresults',data).html());
         // similar to $(data).find('#showresults')
     },
});

or with replaceWith()

// codes

success: function (data){
   $('#showresults').replaceWith($('#showresults',data));
},

The best way to align a div in center both horizontally and vertically will be

HTML

<div></div>

CSS:

div {
    position: absolute;
    top:0;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
    width: 100px;
    height: 100px;
    background-color: blue;
}

The Safe Area Layout Guide helps avoid underlapping System UI elements when positioning content and controls.

The Safe Area is the area in between System UI elements which are Status Bar, Navigation Bar and Tool Bar or Tab Bar. So when you add a Status bar to your app, the Safe Area shrink. When you add a Navigation Bar to your app, the Safe Area shrinks again.

On the iPhone X, the Safe Area provides additional inset from the top and bottom screen edges in portrait even when no bar is shown. In landscape, the Safe Area is inset from the sides of the screens and the home indicator.

This is taken from Apple's video Designing for iPhone X where they also visualize how different elements affect the Safe Area.

Please incre max_iter to 10000 as default value is 1000. Possibly, increasing no. of iterations will help algorithm to converge. For me it converged and solver was -'lbfgs'

log_reg = LogisticRegression(solver='lbfgs',class_weight='balanced', max_iter=10000)

You can use the name property for that particular element. For example to set a border of 2px around an input element with name xyz, you can use;

$(function() {
    $("input[name = 'xyz']").css("border","2px solid red");
})

Normal Dict.values()

will return something like this

dict_values(['value1'])

dict_values(['value2'])

If you want only Values use

• Use this

list(Dict.values())[0] # Under the List

Paint your two canvases onto a third canvas.

I had this same problem and none of the solutions here solved my problem. I had one opaque canvas with another transparent canvas above it. The opaque canvas was completely invisible but the background of the page body was visible. The drawings from the transparent canvas on top were visible while the opaque canvas below it was not.

What you want is known in statistics as mode, and Python of course has a built-in function to do exactly that for you:

>>> from statistics import mode
>>> mode([1, 2, 2, 3, 3, 3, 3, 3, 4, 5, 6, 6, 6])
3

Note that if there is no "most common element" such as cases where the top two are tied, this will raise StatisticsError, because statistically speaking, there is no mode in this case.

One reason to use the body in a delete request is for optimistic concurrency control.

You read version 1 of a record.

GET /some-resource/1
200 OK { id:1, status:"unimportant", version:1 }

Your colleague reads version 1 of the record.

GET /some-resource/1
200 OK { id:1, status:"unimportant", version:1 }

Your colleague changes the record and updates the database, which updates the version to 2:

PUT /some-resource/1 { id:1, status:"important", version:1 }
200 OK { id:1, status:"important", version:2 }

You try to delete the record:

DELETE /some-resource/1 { id:1, version:1 }
409 Conflict

You should get an optimistic lock exception. Re-read the record, see that it's important, and maybe not delete it.

Another reason to use it is to delete multiple records at a time (for example, a grid with row-selection check-boxes).

DELETE /messages
[{id:1, version:2},
{id:99, version:3}]
204 No Content

Notice that each message has its own version. Maybe you can specify multiple versions using multiple headers, but by George, this is simpler and much more convenient.

This works in Tomcat (7.0.52) and Spring MVC (4.05), possibly w earlier versions too:

@RestController
public class TestController {

    @RequestMapping(value="/echo-delete", method = RequestMethod.DELETE)
    SomeBean echoDelete(@RequestBody SomeBean someBean) {
        return someBean;
    }
}

I think it may be the sudo has no access to get ORACLE_HOME.You can do like this.

sudo visudo

modify the text add

Defaults env_keep += "ORACLE_HOME"

then

sudo python setup.py build install

Personally I go with the WebDAV extension 422 Unprocessable Entity.

According to RFC 4918

The 422 Unprocessable Entity status code means the server understands the content type of the request entity (hence a 415 Unsupported Media Type status code is inappropriate), and the syntax of the request entity is correct (thus a 400 Bad Request status code is inappropriate) but was unable to process the contained instructions.

You can return an object of a Class in Java.

If you are returning more than 1 value that are related, then it makes sense to encapsulate them into a class and then return an object of that class.

If you want to return unrelated values, then you can use Java's built-in container classes like Map, List, Set etc. Check the java.util package's JavaDoc for more details.

Both the data import function (here: read.csv()) as well as a global option offer you to say stringsAsFactors=FALSE which should fix this.

Yes, I believe you are creating thousands of objects. If you're looking for an easy way to delete a bunch of them at once, use canvas tags described here. This lets you perform the same operation (such as deletion) on a large number of objects.

For generate Model , controller with resources and migration best command is:

php artisan make:model ModelName -m -cr 

If the web service being invoked uses windows integrated security, creating a NetworkCredential from the current WindowsIdentity should be sufficient to allow the web service to use the current users windows login. However, if the web service uses a different security model, there isn't any way to extract a users password from the current identity ... that in and of itself would be insecure, allowing you, the developer, to steal your users passwords. You will likely need to provide some way for your user to provide their password, and keep it in some secure cache if you don't want them to have to repeatedly provide it.

Edit: To get the credentials for the current identity, use the following:

Uri uri = new Uri("http://tempuri.org/");
ICredentials credentials = CredentialCache.DefaultCredentials;
NetworkCredential credential = credentials.GetCredential(uri, "Basic");

• To undo once: C-/
• To undo twice: C-/ C-/

• To redo once, immediately after undoing: C-g C-/
• To redo twice, immediately after undoing: C-g C-/ C-/. Note that C-g is not repeated.

• To undo immediately again, once: C-g C-/
• To undo immediately again, twice: C-g C-/ C-/

• To redo again, the same…

If you have pressed any keys (whether typing characters or just moving the cursor) since your last undo command, there is no need to type C-g before your next undo/redo. C-g is just a safe key to hit that does nothing on its own, but counts as a non-undo key to signal the end of your undo sequence. Pressing another command such as C-f would work too; it’s just that it would move the cursor from where you had it.

If you hit C-g or another command when you didn’t mean to, and you are now undoing in the wrong direction, simply hit C-g to reverse your direction again. You will have to undo all the way through your accidental redos and undos before you get to the undos you want, but if you just keep hitting C-/, you will eventually reach the state you want. In fact, every state the buffer has ever been in is reachable, if you hit C-g once and then press C-/ enough times.

Alternative shortcuts for undo, other than C-/, are C-_, C-x u, and M-x undo.

See Undo in the Emacs Manual for more details on Emacs’s undo system.

You can also use nuget: https://www.nuget.org/packages/System.Management.Automation/ It is maybe a better option.

I assume you used splice something like this?

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) !== -1) {
        arrayOfObjects.splice(i, 1);
    }
}

All you need to do to fix the bug is decrement i for the next time around, then (and looping backwards is also an option):

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) !== -1) {
        arrayOfObjects.splice(i, 1);
        i--;
    }
}

To avoid linear-time deletions, you can write array elements you want to keep over the array:

var end = 0;

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) === -1) {
        arrayOfObjects[end++] = obj;
    }
}

arrayOfObjects.length = end;

and to avoid linear-time lookups in a modern runtime, you can use a hash set:

const setToDelete = new Set(listToDelete);
let end = 0;

for (let i = 0; i < arrayOfObjects.length; i++) {
    const obj = arrayOfObjects[i];

    if (setToDelete.has(obj.id)) {
        arrayOfObjects[end++] = obj;
    }
}

arrayOfObjects.length = end;

which can be wrapped up in a nice function:

const filterInPlace = (array, predicate) => {_x000D_
    let end = 0;_x000D_
_x000D_
    for (let i = 0; i < array.length; i++) {_x000D_
        const obj = array[i];_x000D_
_x000D_
        if (predicate(obj)) {_x000D_
            array[end++] = obj;_x000D_
        }_x000D_
    }_x000D_
_x000D_
    array.length = end;_x000D_
};_x000D_
_x000D_
const toDelete = new Set(['abc', 'efg']);_x000D_
_x000D_
const arrayOfObjects = [{id: 'abc', name: 'oh'},_x000D_
                        {id: 'efg', name: 'em'},_x000D_
                        {id: 'hij', name: 'ge'}];_x000D_
_x000D_
filterInPlace(arrayOfObjects, obj => !toDelete.has(obj.id));_x000D_
console.log(arrayOfObjects);

If you don’t need to do it in place, that’s Array#filter:

const toDelete = new Set(['abc', 'efg']);
const newArray = arrayOfObjects.filter(obj => !toDelete.has(obj.id));

If the machine you are on is part of the AD domain, it should have its name servers set to the AD name servers (or hopefully use a DNS server path that will eventually resolve your AD domains). Using your example of dc=domain,dc=com, if you look up domain.com in the AD name servers it will return a list of the IPs of each AD Controller. Example from my company (w/ the domain name changed, but otherwise it's a real example):

    mokey 0 /home/jj33 > nslookup example.ad
    Server:         172.16.2.10
    Address:        172.16.2.10#53

    Non-authoritative answer:
    Name:   example.ad
    Address: 172.16.6.2
    Name:   example.ad
    Address: 172.16.141.160
    Name:   example.ad
    Address: 172.16.7.9
    Name:   example.ad
    Address: 172.19.1.14
    Name:   example.ad
    Address: 172.19.1.3
    Name:   example.ad
    Address: 172.19.1.11
    Name:   example.ad
    Address: 172.16.3.2

Note I'm actually making the query from a non-AD machine, but our unix name servers know to send queries for our AD domain (example.ad) over to the AD DNS servers.

I'm sure there's a super-slick windowsy way to do this, but I like using the DNS method when I need to find the LDAP servers from a non-windows server.

Simply You can do it

import time

close_time=time.time()+delay
while True:
      ##bla bla
      ###bla bla
     if time.time()>close_time
         break

Go into settings in Package Center and add http://packages.synocommunity.com/ as a package source. Then you should be able to add it easily via Package Center.

 $(this).attr("name") 

means the name of the select tag not option name.

To get option name

 $("#band_type_choices option:selected").attr('name');

An alternative approach is resample, which can handle duplicate dates in addition to missing dates. For example:

df.resample('D').mean()

resample is a deferred operation like groupby so you need to follow it with another operation. In this case mean works well, but you can also use many other pandas methods like max, sum, etc.

Here is the original data, but with an extra entry for '2013-09-03':

             val
date           
2013-09-02     2
2013-09-03    10
2013-09-03    20    <- duplicate date added to OP's data
2013-09-06     5
2013-09-07     1

And here are the results:

             val
date            
2013-09-02   2.0
2013-09-03  15.0    <- mean of original values for 2013-09-03
2013-09-04   NaN    <- NaN b/c date not present in orig
2013-09-05   NaN    <- NaN b/c date not present in orig
2013-09-06   5.0
2013-09-07   1.0

I left the missing dates as NaNs to make it clear how this works, but you can add fillna(0) to replace NaNs with zeroes as requested by the OP or alternatively use something like interpolate() to fill with non-zero values based on the neighboring rows.

Make your own console in html .... ;-) This can be imprved but you can start with :

if (typeof console == "undefined" || typeof console.log === "undefined") {
    var oDiv=document.createElement("div");
    var attr = document.createAttribute('id'); attr.value = 'html-console';
    oDiv.setAttributeNode(attr);


    var style= document.createAttribute('style');
    style.value = "overflow: auto; color: red; position: fixed; bottom:0; background-color: black; height: 200px; width: 100%; filter: alpha(opacity=80);";
    oDiv.setAttributeNode(style);

    var t = document.createElement("h3");
    var tcontent = document.createTextNode('console');
    t.appendChild(tcontent);
    oDiv.appendChild(t);

    document.body.appendChild(oDiv);
    var htmlConsole = document.getElementById('html-console');
    window.console = {
        log: function(message) {
            var p = document.createElement("p");
            var content = document.createTextNode(message.toString());
            p.appendChild(content);
            htmlConsole.appendChild(p);
        }
    };
}

You could create a user form:

http://www.excel-vba-easy.com/vba-userform-excel-vba.html

You cannot use the VB line-continuation character inside of a string.

SqlQueryString = "Insert into Employee values(" & txtEmployeeNo.Value & _
"','" & txtContractStartDate.Value &  _
"','" & txtSeatNo.Value & _
"','" & txtFloor.Value & "','" & txtLeaves.Value & "')"

If you get this error from within a docker container, e.g. when running npm install inside of an alpine container, the cause could be that the network changed since the container was started.

To solve this, just stop and restart the container

When using with a reactive bootstrap table, i did not find that the

table.classname td {

syntax worked as there was no <table> tag at all. Often modules like this don't use the outer tag but just dive right in maybe using <thead> and <tbody> for grouping at most.

Simply specifying like this worked great though

td.classname {
    max-width: 500px;
    text-overflow: initial;
    white-space: wrap;
    word-wrap: break-word;
}

as it directly overrides the <td> and can be used only on the elements you want to change. Maybe in your case use

thead.medium td {
  font-size: 40px; 
}
tbody.small td {
  font-size:25px;
}

for consistent font sizing with a bigger header.

for %f in (filenamewildcard0, filenamewildcard1, ...) do echo %f >> newtargetfilename_with_path

Same idea as Mike T; might work better under MessyDog's 127 character command line limit

You should use LoadXml method, not Load:

xmlDoc.LoadXml(myXML); 

Load method is trying to load xml from a file and LoadXml from a string. You could also use XPath:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xml);

string xpath = "myDataz/listS/sog";
var nodes = xmlDoc.SelectNodes(xpath);

foreach (XmlNode childrenNode in nodes)
{
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("//field1").Value);
} 

In addition to the other answers, note that a multidimensional array is allocated as one big chunky object on the heap. This has some implications:

1. Some multidimensional arrays will get allocated on the Large Object Heap (LOH) where their equivalent jagged array counterparts would otherwise not have.
2. The GC will need to find a single contiguous free block of memory to allocate a multidimensional array, whereas a jagged array might be able to fill in gaps caused by heap fragmentation... this isn't usually an issue in .NET because of compaction, but the LOH doesn't get compacted by default (you have to ask for it, and you have to ask every time you want it).
3. You'll want to look into <gcAllowVeryLargeObjects> for multidimensional arrays way before the issue will ever come up if you only ever use jagged arrays.

1. Create a manual segue (ctrl-drag from File’s Owner to Exit),
2. Choose it in the Left Controller Menu below green EXIT button.

This alternative example stores the local time as Integer to save the 20 bytes. The work is done in the field default, Update-trigger, and View. strftime must use '%s' (single-quotes) because "%s" (double-quotes) threw a 'Not Constant' error on me.

Create Table Demo (
   idDemo    Integer    Not Null Primary Key AutoIncrement
  ,DemoValue Text       Not Null Unique
  ,DatTimIns Integer(4) Not Null Default (strftime('%s', DateTime('Now', 'localtime'))) -- get Now/UTC, convert to local, convert to string/Unix Time, store as Integer(4)
  ,DatTimUpd Integer(4)     Null
);

Create Trigger trgDemoUpd After Update On Demo Begin
  Update Demo Set
    DatTimUpd  =                          strftime('%s', DateTime('Now', 'localtime'))  -- same as DatTimIns
  Where idDemo = new.idDemo;
End;

Create View If Not Exists vewDemo As Select -- convert Unix-Times to DateTimes so not every single query needs to do so
   idDemo
  ,DemoValue
  ,DateTime(DatTimIns, 'unixepoch') As DatTimIns -- convert Integer(4) (treating it as Unix-Time)
  ,DateTime(DatTimUpd, 'unixepoch') As DatTimUpd --   to YYYY-MM-DD HH:MM:SS
From Demo;

Insert Into Demo (DemoValue) Values ('One');                      -- activate the field Default
-- WAIT a few seconds --    
Insert Into Demo (DemoValue) Values ('Two');                      -- same thing but with
Insert Into Demo (DemoValue) Values ('Thr');                      --   later time values

Update Demo Set DemoValue = DemoValue || ' Upd' Where idDemo = 1; -- activate the Update-trigger

Make sure you have a getter in House address class and then use:

for(int i = 0; i < houseAddress.size(); i++) {   
    System.out.print(houseAddress.get(i)**.getAddress()**);
}

i have same this because in httpd.conf in apache PHPIniDir D:/wamp/bin/php/php5.5.12 that was incorrect

An object is defined by an OBJECT_ID, which is unique. If A and B are objects and A == B is true, then they are the very same object, they have the same data and methods, but, this is also true:

A.OBJECT_ID == B.OBJECT_ID

if A.Equals(B) is true, that means that the two objects are in the same state, but this doesn't mean that A is the very same as B.

Strings are objects.

Note that the == and Equals operators are reflexive, simetric, tranzitive, so they are equivalentic relations (to use relational algebraic terms)

What this means: If A, B and C are objects, then:

(1) A == A is always true; A.Equals(A) is always true (reflexivity)

(2) if A == B then B == A; If A.Equals(B) then B.Equals(A) (simetry)

(3) if A == B and B == C, then A == C; if A.Equals(B) and B.Equals(C) then A.Equals(C) (tranzitivity)

Also, you can note that this is also true:

(A == B) => (A.Equals(B)), but the inverse is not true.

A B =>
0 0 1
0 1 1
1 0 0
1 1 1

Example of real life: Two Hamburgers of the same type have the same properties: they are objects of the Hamburger class, their properties are exactly the same, but they are different entities. If you buy these two Hamburgers and eat one, the other one won't be eaten. So, the difference between Equals and ==: You have hamburger1 and hamburger2. They are exactly in the same state (the same weight, the same temperature, the same taste), so hamburger1.Equals(hamburger2) is true. But hamburger1 == hamburger2 is false, because if the state of hamburger1 changes, the state of hamburger2 not necessarily change and vice versa.

If you and a friend get a Hamburger, which is yours and his in the same time, then you must decide to split the Hamburger into two parts, because you.getHamburger() == friend.getHamburger() is true and if this happens: friend.eatHamburger(), then your Hamburger will be eaten too.

I could write other nuances about Equals and ==, but I'm getting hungry, so I have to go.

To deserialize the response need to use HashMap:

String resp = ...//String output from your source

Gson gson = new GsonBuilder().create();
gson.fromJson(resp,TheResponse.class);

class TheResponse{
 HashMap<String,Song> songs;
}

class Song{
  String id;
  String pos;
}

Use a shell script:

#!/bin/bash
# myscript
FOO=bar
somecommand someargs | somecommand2

> ./myscript

To reference a commit, simply write its SHA-hash, and it'll automatically get turned into a link.

This is the benchmark I have run after finding some articles around the net.

With 2.4.0 the winner is re.match?(str) (as suggested by @wiktor-stribizew), on previous versions, re =~ str seems to be fastest, although str =~ re is almost as fast.

#!/usr/bin/env ruby
require 'benchmark'

str = "aacaabc"
re = Regexp.new('a+b').freeze

N = 4_000_000

Benchmark.bm do |b|
    b.report("str.match re\t") { N.times { str.match re } }
    b.report("str =~ re\t")    { N.times { str =~ re } }
    b.report("str[re]  \t")    { N.times { str[re] } }
    b.report("re =~ str\t")    { N.times { re =~ str } }
    b.report("re.match str\t") { N.times { re.match str } }
    if re.respond_to?(:match?)
        b.report("re.match? str\t") { N.times { re.match? str } }
    end
end

C++03 3.10/1 says: "Every expression is either an lvalue or an rvalue." It's important to remember that lvalueness versus rvalueness is a property of expressions, not of objects.

Lvalues name objects that persist beyond a single expression. For example, obj , *ptr , ptr[index] , and ++x are all lvalues.

Rvalues are temporaries that evaporate at the end of the full-expression in which they live ("at the semicolon"). For example, 1729 , x + y , std::string("meow") , and x++ are all rvalues.

The address-of operator requires that its "operand shall be an lvalue". if we could take the address of one expression, the expression is an lvalue, otherwise it's an rvalue.

 &obj; //  valid
 &12;  //invalid

With VLC i'm able to transcode a live RTSP stream (mpeg4) to an HTTP stream in a OGG format (Vorbis/Theora). The quality is poor but the video work in Chrome 9. I have also tested with a trancoding in WEBM (VP8) but it's don't seem to work (VLC have the option but i don't know if it's really implemented for now..)

The first to have a doc on this should notify us ;)

If you are still interested, Chris Wolf made a prototype implementation of SQLite with Stored Procedures. You can find the details at his blog post: Adding Stored Procedures to SQLite

In case you want to change the status code because of an exception, with JAX-RS 2.0 you can implement an ExceptionMapper like this. This handles this kind of exception for the whole app.

@Provider
public class UnauthorizedExceptionMapper implements ExceptionMapper<EJBAccessException> {

    @Override
    public Response toResponse(EJBAccessException exception) {
        return Response.status(Response.Status.UNAUTHORIZED.getStatusCode()).build();
    }

    static Point rotate_point(double cx, double cy, double angle, Point p)
    {
        double s = Math.Sin(angle);
        double c = Math.Cos(angle);
        // translate point back to origin:

        // rotate point
        double Xnew = p.X * c - p.Y * s;
        double Ynew = p.X * s + p.Y * c;

Someone pointed me to args4j lately which is annotation based. I really like it!

I have my own api back end with laravel, so I usually just the following:

$(document).ready( function() {

    $.getJSON( "http://api.whoisdoma.com/v1/ip/visitor?api_key=key",
        function(data){
          alert( data.ip);
        }
    );

});

For extra security, I provide an api key which is required to get results.

You can use this, just think Job is the name of the model to which you are adding index cader_id:

class AddCaderIdToJob < ActiveRecord::Migration[5.2]
  def change
    change_table :jobs do |t|
      t.integer :cader_id
      t.index :cader_id
    end
  end
end

If you're still getting this error message while using the WCF Test Client, it's because the client has a separate MaxBufferSize setting.

To correct the issue:

1. Right-Click on the Config File node at the bottom of the tree
2. Select Edit with SvcConfigEditor

A list of editable settings will appear, including MaxBufferSize.

Note: Auto-generated proxy clients also set MaxBufferSize to 65536 by default.

This question's bit old, but, there's a tricky scenario which also leads to this error:

In controller:

ViewBag.id = //id from querystring
List<string> = GrabDataFromDBByID(ViewBag.id).Select(a=>a.ToString());

The above code will lead to an error in this part: .Select(a=>a.ToString()) because of the below reason: You're passing a ViewBag.id to a method which in compiler, it doesn't know the type, so there might be several methods with the same name and different parameters let's say:

GrabDataFromDBByID(string)
GrabDataFromDBByID(int)
GrabDataFromDBByID(whateverType)

So to prevent this case, either explicitly cast the ViewBag or create another variable storing it.

import java.io.*;


public class FileRead {


    public static void main(String[] args) throws IOException {


        File f=new File("C:\\Documents and Settings\\abc\\Desktop\\abc.pdf");

        OutputStream oos = new FileOutputStream("test.pdf");

        byte[] buf = new byte[8192];

        InputStream is = new FileInputStream(f);

        int c = 0;

        while ((c = is.read(buf, 0, buf.length)) > 0) {
            oos.write(buf, 0, c);
            oos.flush();
        }

        oos.close();
        System.out.println("stop");
        is.close();

    }

}

The easiest way so far. Hope this helps.

without using the System.arraycopy method you can delete an element from an array with the following

    int i = 0;
    int x = 0;
    while(i < oldArray.length){
        if(oldArray[i] == 3)i++;

        intArray[x] = oldArray[i];
        i++;
        x++;
    }

where 3 is the value you want to remove.

IIRC @Valid isn't a Spring annotation but a JSR-303 annotation (which is the Bean Validation standard). What it does is it basically checks if the data that you send to the method is valid or not (it will validate the scriptFile for you).

Example using std::string find method:

#include <iostream>
#include <string>

int main (){
    std::string str ("There are two needles in this haystack with needles.");
    std::string str2 ("needle");

    size_t found = str.find(str2);
    if(found!=std::string::npos){ 
        std::cout << "first 'needle' found at: " << found << '\n';
    }

    return 0;
}

Result:

first 'needle' found at: 14.

I found problems with the two common ways of doing this:

1. Doing this with custom headers (<customHeaders>) in web.config allows different deployments of the same application to have this set differently. I see this as one more thing that can go wrong, so I think it's better if the application specifies this in code. Also, IIS6 doesn't support this.

2. Including an HTML <meta> tag in a Web Forms Master Page or MVC Layout Page seems better than the above. However, if some pages don't inherit from these then the tag needs to be duplicated, so there's a potential maintainability and reliability problem.

3. Network traffic could be reduced by only sending the X-UA-Compatible header to Internet Explorer clients.

Well-Structured Applications

If your application is structured in a way that causes all pages to ultimately inherit from a single root page, include the <meta> tag as shown in the other answers.

Legacy Applications

Otherwise, I think the best way to do this is to automatically add the HTTP header to all HTML responses. One way to do this is using an IHttpModule:

public class IeCompatibilityModeDisabler : IHttpModule
{
    public void Init(HttpApplication context)
    {
        context.PreSendRequestHeaders += (sender, e) => DisableCompatibilityModeIfApplicable();
    }

    private void DisableCompatibilityModeIfApplicable()
    {
        if (IsIe && IsPage)
            DisableCompatibilityMode();
    }

    private void DisableCompatibilityMode()
    {
        var response = Context.Response;
        response.AddHeader("X-UA-Compatible", "IE=edge");
    }

    private bool IsIe { get { return Context.Request.Browser.IsBrowser("IE"); } }

    private bool IsPage { get { return Context.Handler is Page; } }

    private HttpContext Context { get { return HttpContext.Current; } }

    public void Dispose() { }
}

IE=edge indicates that IE should use its latest rendering engine (rather than compatibility mode) to render the page.

It seems that HTTP modules are often registered in the web.config file, but this brings us back to the first problem. However, you can register them programmatically in Global.asax like this:

public class Global : HttpApplication
{
    private static IeCompatibilityModeDisabler module;

    void Application_Start(object sender, EventArgs e)
    {
        module = new IeCompatibilityModeDisabler();
    }

    public override void Init()
    {
        base.Init();
        module.Init(this);
    }
}

Note that it is important that the module is static and not instantiated in Init so that there is only one instance per application. Of course, in a real-world application an IoC container should probably be managing this.

Advantages

• Overcomes the problems outlined at the start of this answer.

Disadvantages

• Website admins don't have control over the header value. This could be a problem if a new version of Internet Explorer comes out and adversely affects the rendering of the website. However, this could be overcome by having the module read the header value from the application's configuration file instead of using a hard-coded value.
• This may require modification to work with ASP.NET MVC.
• This doesn't work for static HTML pages.
• The PreSendRequestHeaders event in the above code doesn't seem to fire in IIS6. I haven't figured out how to resolve this bug yet.

Searching multiple fields at once can be done like so...

function search($search)
{
    $sql = "SELECT * FROM some_table
    WHERE UPPER(a_name) LIKE ?
    OR
    UPPER(a_full_name) LIKE ?
    OR
    UPPER(a_city) LIKE ?
    OR
    UPPER(a_code) LIKE ?
    ";
    $arr = array_map(array($this,"wrapLIKE"),array($search, $search, $search, $search));
    $r = $this->db->query($sql, $arr);
    return $r;
}

function wrapLIKE($string)
{
    return strtoupper("%$string%");
}

The simplest method is:

int[] ints = new [] { 10, 20, 10, 34, 113 };

List<int> lst = ints.ToList();

or

List<int> lst = new List<int>();
lst.AddRange(ints);

It's not unique to WP7--it's present on all .Net objects. It sort of does what you describe, but I would not recommend it as a unique identifier in your apps, as it is not guaranteed to be unique.

Object.GetHashCode Method

I hope it helps someone.

You're thinking it wrong.

What you are trying to do:

If stdin exists use it, else check whether the user supplied a filename.

What you should be doing instead:

If the user supplies a filename, then use the filename. Else use stdin.

You cannot know the total length of an incoming stream unless you read it all and keep it buffered. You just cannot seek backwards into pipes. This is a limitation of how pipes work. Pipes are not suitable for all tasks and sometimes intermediate files are required.

I used the CSS in the accepted answer here for my responsive YouTube videos - worked great right up until YouTube updated their system around the start of August 2015. The videos on YouTube are the same dimensions but for whatever reason the CSS in the accepted answer now letterboxes all our videos. Black bands across top and bottom.

I've tickered around with the sizes and settled on getting rid of the top padding and changing the bottom padding to 56.45%. Seems to look good.

.videowrapper {
    position: relative;
    padding-bottom: 56.45%;
    height: 0;
}

var a;
scanf("%s\n", n);

I tested this out in ObjC, and maybe this will be useful.

In Targets -> Build Phases

Make sure the .xib is added to Copy Bundle Resources, if it is not present then add .xib file.

Use basic programming composition: create a method and pass the same function to click and hover as a callback.

var hoverOrClick = function () {
    // do something common
}
$('#target').click(hoverOrClick).hover(hoverOrClick);

Second way: use bindon:

$('#target').on('click mouseover', function () {
    // Do something for both
});

jQuery('#target').bind('click mouseover', function () {
    // Do something for both
});

     <item name="android:textColorSecondary">@color/mediumGray</item>
     <item name="colorControlNormal">@color/red</item>
 </style>

In layout use theme:

<RadioButton
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:theme="@style/RadioButton" />

For API 21 and more

Just use buttonTint

 <RadioButton
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:buttonTint="@color/green" />

When I checked out a new project from the repository, I did not see the icon overlays.

I started looking for solutions and came to this question.

While reading answers, I noticed the icon overlays appeared on my checkout project.

I guess it just took a few minutes for the icons to appear.

I thought this might be useful before people panic quickly and start editing the registry.

You can use howfat which also displays dependency statistics:

npx howfat -r tree jasmine

The answer of Pascal Thivent helped me out, too. But if you manage your plugins within the <pluginManagement>element, you have to define the assembly again outside of the plugin management, or else the dependencies are not packed in the jar if you run mvn install.

This question is really old, but I came across this page when I was looking for the easiest and quickest way to do this. Using Webpack is much simpler:

install webpack-dev-server

npm i -g webpack-dev-server

start webpack-dev-server with https

webpack-dev-server --https

In Scala,

val ticks = "'([^']*)'".r

ticks findFirstIn mydata match {
    case Some(ticks(inside)) => println(inside)
    case _ => println("nothing")
}

for (ticks(inside) <- ticks findAllIn mydata) println(inside) // multiple matches

val Some(ticks(inside)) = ticks findFirstIn mydata // may throw exception

val ticks = ".*'([^']*)'.*".r    
val ticks(inside) = mydata // safe, shorter, only gets the first set of ticks

Simple line below works just fine:

header("Location: ?");

Project Files Services Tabls

go files tabs

drag drop file to libs files hover.

return project tabs and what are you see :)

It's also good note that outline: none can be applied to both <button> tags and input[type=button] to remove the browser-applied border on click.

A lot of correct answers, but I haven't found this one: Collections cannot be sorted, you can only iterate through them.

Now you can iterate over them and create a new sorted something. Follow the answers here for that.

To add some explanation to all said before me, I should give you some examples to understand logical concepts.

var name = false || "Mohsen"; # name equals to Mohsen
var family = true || "Alizadeh" # family equals to true

It means if the left side evaluated as a true statement it will be finished and the left side will be returned and assigned to the variable. in other cases the right side will be returned and assigned.

And operator have the opposite structure like below.

var name = false && "Mohsen" # name equals to false
var family = true && "Alizadeh" # family equals to Alizadeh

A common mistake is

mainWB.Sheets.Add(After:=Sheets.Count)

which leads to Error 1004. Although it is not clear at all from the official documentation, it turns out that the 'After' parameter cannot be an integer, it must be a reference to a sheet in the same workbook.

The default behavior of os.walk() is to walk from root to leaf. Set topdown=False in os.walk() to walk from leaf to root.

No need to add extra elements. While flexbox uses very non-intuitive property names if you know what it can do you'll find yourself using it quite often.

<div style="display: flex; justify-content: space-between;">
<span>Item Left</span>
<span>Item Right</span>
</div>

Plan on needing this often?

.align_between {display: flex; justify-content: space-between;}

I see other people using secondary words in the primary position which makes a mess of information hierarchy. If align is the primary task and right, left, and/or between are the secondary the class should be .align_outer, not .outer_align as it will make sense as you vertically scan your code:

.align_between {}
.align_left {}
.align_outer {}
.align_right {}

Good habits over time will allow you to get to bed sooner than later.

You have to use Javascript submit function on your form object. Take a look in other functions.

<form action="showMessage.jsp" method="post">
    <a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
    <input type="hidden" name="mess" value=<%=n%>/>
</form>

From R..'s answer:

However, this is probably a very bad idea, because the resulting type is an array type, but users of it won't see that it's an array type. If used as a function argument, it will be passed by reference, not by value, and the sizeof for it will then be wrong.

Users who don't see that it's an array will most likely write something like this (which fails):

#include <stdio.h>

typedef int twoInts[2];

void print(twoInts *twoIntsPtr);
void intermediate (twoInts twoIntsAppearsByValue);

int main () {
    twoInts a;
    a[0] = 0;
    a[1] = 1;
    print(&a);
    intermediate(a);
    return 0;
}
void intermediate(twoInts b) {
    print(&b);
}

void print(twoInts *c){
    printf("%d\n%d\n", (*c)[0], (*c)[1]);
}

It will compile with the following warnings:

In function ‘intermediate’:
warning: passing argument 1 of ‘print’ from incompatible pointer type [enabled by default]
    print(&b);
     ^
note: expected ‘int (*)[2]’ but argument is of type ‘int **’
    void print(twoInts *twoIntsPtr);
         ^

And produces the following output:

0
1
-453308976
32767

Found this post and I realize it's a bit old, but I think I might have an answer. This handles the click on the cross, backspacing and hitting the ESC key. I am sure it could probably be written better - I'm still relatively new to javascript. Here is what I ended up doing - I am using jQuery (v1.6.4):

var searchVal = ""; //create a global var to capture the value in the search box, for comparison later
$(document).ready(function() {
  $("input[type=search]").keyup(function(e) {
    if (e.which == 27) {  // catch ESC key and clear input
      $(this).val('');
    }
    if (($(this).val() === "" && searchVal != "") || e.which == 27) {
      // do something
      searchVal = "";
    }
    searchVal = $(this).val();
  });
  $("input[type=search]").click(function() {
    if ($(this).val() != filterVal) {
      // do something
      searchVal = "";
    }
  });
});

Using begin and end seemed to work for me to select a range of elements. This gives me three separate lists. The first list with items 1-9, second list with items 10-18, and the last list with items 11-25.

                    <ul>
                        <c:forEach items="${actionBean.top25Teams}" begin="0" end="8" var="team" varStatus="counter">
                            <li>${team.name}</li>                               
                        </c:forEach> 
                    </ul>

                    <ul>
                        <c:forEach items="${actionBean.top25Teams}" begin="9" end="17" var="team" varStatus="counter">
                            <li>${team.name}</li>                               
                        </c:forEach> 
                    </ul>

                    <ul>
                        <c:forEach items="${actionBean.top25Teams}" begin="18" end="25" var="team" varStatus="counter">
                            <li>${team.name}</li>                               
                        </c:forEach> 
                    </ul>

During the download of wamp server from wampserver website you get a warning..

WARNING : Vous devez avoir installé Visual Studio 2012 : VC 11 vcredist_x64/86.exe Visual Studio 2012 VC 11 vcredist_x64/86.exe : http://www.microsoft.com/en-us/download/details.aspx?id=30679

So if you install the vcredist_xxx.exe it will be ok

If you are posting JSON to Django, I think you want request.body (request.raw_post_data on Django < 1.4). This will give you the raw JSON data sent via the post. From there you can process it further.

Here is an example using JavaScript, jQuery, jquery-json and Django.

JavaScript:

var myEvent = {id: calEvent.id, start: calEvent.start, end: calEvent.end,
               allDay: calEvent.allDay };
$.ajax({
    url: '/event/save-json/',
    type: 'POST',
    contentType: 'application/json; charset=utf-8',
    data: $.toJSON(myEvent),
    dataType: 'text',
    success: function(result) {
        alert(result.Result);
    }
});

Django:

def save_events_json(request):
    if request.is_ajax():
        if request.method == 'POST':
            print 'Raw Data: "%s"' % request.body   
    return HttpResponse("OK")

Django < 1.4:

  def save_events_json(request):
    if request.is_ajax():
        if request.method == 'POST':
            print 'Raw Data: "%s"' % request.raw_post_data
    return HttpResponse("OK")

To checks for all 'empties' like null, undefined, '', ' ', {}, [].

var isEmpty = function(data) {
    if(typeof(data) === 'object'){
        if(JSON.stringify(data) === '{}' || JSON.stringify(data) === '[]'){
            return true;
        }else if(!data){
            return true;
        }
        return false;
    }else if(typeof(data) === 'string'){
        if(!data.trim()){
            return true;
        }
        return false;
    }else if(typeof(data) === 'undefined'){
        return true;
    }else{
        return false;
    }
}

Use cases and results.

console.log(isEmpty()); // true
console.log(isEmpty(null)); // true
console.log(isEmpty('')); // true
console.log(isEmpty('  ')); // true
console.log(isEmpty(undefined)); // true
console.log(isEmpty({})); // true
console.log(isEmpty([])); // true
console.log(isEmpty(0)); // false
console.log(isEmpty('Hey')); // false

Just create a new branch:

git checkout -b newBranch

And if you do git status you'll see that the state of the code hasn't changed and you can commit it to the new branch.

JSON.stringify(j, null, 4) would give you beautified JSON in case you need beautification also

The second parameter is replacer. It can be used as Filter where you can filter out certain key values when stringifying. If set to null it will return all key value pairs

A default constructor is a constructor that either has no parameters, or if it has parameters, all the parameters have default values.

string[] lines = text.Split(
  Environment.NewLine.ToCharArray(), 
  StringSplitOptions.RemoveEmptyStrings);

The RemoveEmptyStrings option will make sure you don't have empty entries due to \n following a \r

(Edit to reflect comments:) Note that it will also discard genuine empty lines in the text. This is usually what I want but it might not be your requirement.

Your problem is that your phones object doesn't have a length property (unless you define it somewhere in the JSON that you return) as objects aren't the same as arrays, even when used as associative arrays. If the phones object was an array it would have a length. You have two options (maybe more).

1. Change your JSON structure (assuming this is possible) so that 'phones' becomes

   "phones":[{"number":"XXXXXXXXXX","type":"mobile"},{"number":"XXXXXXXXXX","type":"mobile"}]
   

   (note there is no word-numbered identifier for each phone as they are returned in a 0-indexed array). In this response phones.length will be valid.

2. Iterate through the objects contained within your phones object and count them as you go, e.g.

   var key, count = 0;
   for(key in data.phones) {
     if(data.phones.hasOwnProperty(key)) {
       count++;
     }
   }
   

If you're only targeting new browsers option 2 could look like this

The simplest way to convert from the old style to the new (Express 3.x) style is like this:

var server = app.listen(8080);
console.log('Listening on port: ' + server.address().port);

Pre 3.x it works like this:

/* This no longer works */
app.listen(8080);
console.log('Listening on port: ' + app.address().port);

Use

__DIR__

to get the current path of the script and this should fix your problem.

So:

require_once(__DIR__.'/../class/user.php');

This will prevent cases where you can run a PHP script from a different folder and therefore the relatives paths will not work.

Edit: slash problem fixed

1. Serializable

@see http://docs.oracle.com/javase/7/docs/api/java/io/Serializable.html

Interface of what?

• is a standard Java interface

Speed

• slower than Parcelable

2. Parcelable

@see http://developer.android.com/reference/android/os/Parcelable.html

Interface of what?

• is android.os interface
  • which means Google developped Parcelable for better performance on android

Speed

• faster ( because it is optimized for usage on android development)

> In Conclusion

Be aware that Serializable is a standard Java interface, and Parcelable is for Android Development

Mr. Alien's answer is perfect, but anyway I don't recommend to use <div class="clear"></div> because it just a hack which makes your markup dirty. This is useless empty div in terms of bad structure and semantic, this also makes your code not flexible. In some browsers this div causes additional height and you have to add height: 0; which even worse. But real troubles begin when you want to add background or border around your floated elements - it just will collapse because web was designed badly. I do recommend to wrap floated elements into container which has clearfix CSS rule. This is hack as well, but beautiful, more flexible to use and readable for human and SEO robots.
