The solution that worked for me was to right click on the project --> Maven --> Update Project then click OK.

In IIS7 with integrated mode, Current is not available in Application_Start. There is a similar thread here.

Instead of using the "c" tags, you could also do the following:

<h:outputLink value="Images/thumb_02.jpg" target="_blank" rendered="#{not empty user or user.userId eq 0}" />
<h:graphicImage value="Images/thumb_02.jpg" rendered="#{not empty user or user.userId eq 0}" />

<h:outputLink value="/DisplayBlobExample?userId=#{user.userId}" target="_blank" rendered="#{not empty user and user.userId neq 0}" />
<h:graphicImage value="/DisplayBlobExample?userId=#{user.userId}" rendered="#{not empty user and user.userId neq 0}"/>

I think that's a little more readable alternative to skuntsel's alternative answer and is utilizing the JSF rendered attribute instead of nesting a ternary operator. And off the answer, did you possibly mean to put your image in between the anchor tags so the image is clickable?

Make sure your

AutowiringSpringBeanJobFactory extends SpringBeanJobFactory 

dependency is pulled from

    "org.springframework:spring-context-support:4..."

and NOT from

    "org.springframework:spring-support:2..."

It wanted me to use

@Override
public Job newJob(TriggerFiredBundle bundle, Scheduler scheduler)

instead of

@Override
protected Object createJobInstance(final TriggerFiredBundle bundle)

so was failing to autowire job instance.

In the package explorer, right-click on the package and select New -> File, then enter the filename including the ".properties" suffix.

Say you have the following DataFrame:

>>> df = pd.DataFrame([['hello', 'hello world'], ['abcd', 'defg']], columns=['a','b'])
>>> df
       a            b
0  hello  hello world
1   abcd         defg

You can always use the in operator in a lambda expression to create your filter.

>>> df.apply(lambda x: x['a'] in x['b'], axis=1)
0     True
1    False
dtype: bool

The trick here is to use the axis=1 option in the apply to pass elements to the lambda function row by row, as opposed to column by column.

I think that really depends on the use case. In many cases it might be more beneficial to use a proper object model (instead of rendering the date to a string), like so:

{
"person" :
      {
 "name" : {
   "first": "Tom",
   "middle": "M",
  ...
}
 "dob" :  {
         "year": 2012,
         "month": 4,
         "day": 23,
         "hour": 18,
         "minute": 25,
         "second": 43,
         "timeZone": "America/New_York"
    }   
   }
}

Admittedly this is more verbose than RFC 3339 but:

• it's human readable as well
• it implements a proper object model (as in OOP, as far as JSON permits it)
• it supports time zones (not just the UTC offset at the given date and time)
• it can support smaller units like milliseconds, nanoseconds, ... or simply fractional seconds
• it doesn't require a separate parsing step (to parse the date-time string), the JSON parser will do everything for you
• easy creation with any date-time framework or implementation in any language
• can easily be extended to support other calendar scales (Hebrew, Chinese, Islamic ...) and eras (AD, BC, ...)
• it's year 10000 safe ;-) (RFC 3339 isn't)
• supports all-day dates and floating times (Javascript's Date.toJSON() doesn't)

I don't think that correct sorting (as noted by funroll for RFC 3339) is a feature that's really needed when serializing a date to JSON. Also that's only true for date-times having the same time zone offset.

Update! You can access the Android filesystem via Android Device Monitor. In Android Studio go to Tools >> Android >> Android Device Monitor.

Note that you can run your app in the simulator while using the Android Device Monitor. But you cannot debug you app while using the Android Device Monitor.

On technologies with message loops (not sure if ASP is one of them), you can block the loop and process messages until the task is over, and use ContinueWith to unblock the code:

public void WaitForTask(Task task)
{
    DispatcherFrame frame = new DispatcherFrame();
    task.ContinueWith(t => frame.Continue = false));
    Dispatcher.PushFrame(frame);
}

This approach is similar to blocking on ShowDialog and still keeping the UI responsive.

The easiest way to do this is to format a cell the way you want it, then use the "cell format ..." contextual menu to get to the fill and format colours, use the "more colors ..." button to get to the hexagon colour selector, select the custom tab.

The RGB colours are as in the table at the bottom of the pane. If you prefer HSL values change the color model from RGB to HSL. I have used this to change the saturation on my bad cells. A higher luminosity gives a worse results and the shade of all the cells is the same just the deepness of the colour is modified.

There is one another technique to identify your class You can store ref to your class in instance like bellow.

class MyClass {
    static myStaticProperty = 'default';
    constructor() {
        this.__class__ = new.target;
        this.showStaticProperty = function() {
            console.log(this.__class__.myStaticProperty);
        }
    }
}

class MyChildClass extends MyClass {
    static myStaticProperty = 'custom';
}

let myClass = new MyClass();
let child = new MyChildClass();

myClass.showStaticProperty(); // default
child.showStaticProperty(); // custom

myClass.__class__ === MyClass; // true
child.__class__ === MyClass; // false
child.__class__ === MyChildClass; // true

Adding my own experience for those who are experiencing this in the future. My specific error was

Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known'

It turns out that this was actually because I had reach the maximum number of open files on my system. It had nothing to do with failed connections, or even a DNS error as indicated.

thisReader.GetString(int columnIndex)

From the mysql console:

mysql> use DATABASE_NAME;

mysql> source path/to/file.sql;

make sure there is no slash before path if you are referring to a relative path... it took me a while to realize that! lol

You need a click listener which calls addActivityItem if less than 2 options exist:

var activities = document.getElementById("activitySelector");

activities.addEventListener("click", function() {
    var options = activities.querySelectorAll("option");
    var count = options.length;
    if(typeof(count) === "undefined" || count < 2)
    {
        addActivityItem();
    }
});

activities.addEventListener("change", function() {
    if(activities.value == "addNew")
    {
        addActivityItem();
    }
});

function addActivityItem() {
    // ... Code to add item here
}

A live demo is here on JSfiddle.

In a BST, all values descending on the left side of a node are less than (or equal to, see later) the node itself. Similarly, all values descending on the right side of a node are greater than (or equal to) that node value^(a).

Some BSTs may choose to allow duplicate values, hence the "or equal to" qualifiers above. The following example may clarify:

     14
    /  \
  13    22
 /     /  \
1    16    29
          /  \
        28    29

This shows a BST that allows duplicates^(b) - you can see that to find a value, you start at the root node and go down the left or right subtree depending on whether your search value is less than or greater than the node value.

This can be done recursively with something like:

def hasVal (node, srchval):
    if node == NULL:
         return false
    if node.val == srchval:
        return true
    if node.val > srchval:
        return hasVal (node.left, srchval)
    return hasVal (node.right, srchval)

and calling it with:

foundIt = hasVal (rootNode, valToLookFor)

Duplicates add a little complexity since you may need to keep searching once you've found your value, for other nodes of the same value. Obviously that doesn't matter for hasVal since it doesn't matter how many there are, just whether at least one exists. It will however matter for things like countVal, since it needs to know how many there are.

^(a) You could actually sort them in the opposite direction should you so wish provided you adjust how you search for a specific key. A BST need only maintain some sorted order, whether that's ascending or descending (or even some weird multi-layer-sort method like all odd numbers ascending, then all even numbers descending) is not relevant.

^(b) Interestingly, if your sorting key uses the entire value stored at a node (so that nodes containing the same key have no other extra information to distinguish them), there can be performance gains from adding a count to each node, rather than allowing duplicate nodes.

The main benefit is that adding or removing a duplicate will simply modify the count rather than inserting or deleting a new node (an action that may require re-balancing the tree).

So, to add an item, you first check if it already exists. If so, just increment the count and exit. If not, you need to insert a new node with a count of one then rebalance.

To remove an item, you find it then decrement the count - only if the resultant count is zero do you then remove the actual node from the tree and rebalance.

Searches are also quicker given there are fewer nodes but that may not be a large impact.

For example, the following two trees (non-counting on the left, and counting on the right) would be equivalent (in the counting tree, i.c means c copies of item i):

     __14__                    ___22.2___
    /      \                  /          \
  14        22             7.1            29.1
 /  \      /  \           /   \          /    \
1    14  22    29      1.1     14.3  28.1      30.1
 \            /  \
  7         28    30

Removing the leaf-node 22 from the left tree would involve rebalancing (since it now has a height differential of two) the resulting 22-29-28-30 subtree such as below (this is one option, there are others that also satisfy the "height differential must be zero or one" rule):

\                      \
 22                     29
   \                   /  \
    29      -->      28    30
   /  \             /
 28    30         22

Doing the same operation on the right tree is a simple modification of the root node from 22.2 to 22.1 (with no rebalancing required).

Try this :

   $i = 0;    
    while($row = mysqli_fetch_array($result)) {  

            $posts['post_id'] = $row[$i]['post_id'];
            $posts['post_title'] = $row[$i]['post_title'];
            $posts['type'] = $row[$i]['type'];
            $posts['author'] = $row[$i]['author'];  

        }   
    $i++;
    }

print_r($posts);

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

Try this instead:

$journalName = str_replace(' ', '_', $journalName);

to remove white space

You may also want to check whether the double is higher than the max Int value before trying to convert the value to an Int.

let number = Double.infinity
if number >= Double(integerLiteral: Int64.max) {
  let rounded = Int.max
} else {
  let rounded = Int(number.rounded())
}

Simple and Efficient Solution : use Volley

 StringRequest stringRequest = new StringRequest(Request.Method.GET, finalUrl ,
           new Response.Listener<String>() {
                    @Override
                    public void onResponse(String){
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            HashMap<String, Object> responseHashMap = new HashMap<>(Utility.toMap(jsonObject)) ;
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d("api", error.getMessage().toString());
            }
        });

        RequestQueue queue = Volley.newRequestQueue(context) ;
        queue.add(stringRequest) ;

keytool -import -v -alias cacerts -keystore cacerts.jks -storepass changeit -file C:\cacerts.cer

You can grant system privileges with or without the admin option. The default being without admin option.

GRANT CREATE SESSION TO username

or with admin option:

GRANT CREATE SESSION TO username WITH ADMIN OPTION

The Grantee with the ADMIN OPTION can grant and revoke privileges to other users

I have a simple workaround.

Suppose your URI has a string stringdata that is too long. You can simply break it into a number of parts depending on the limits of your server. Then submit the first one, in my case to write a file. Then submit the next ones to append to previously added data.

Have you tried using the fb:// protocol?

To have them like your page when they scan the qr code, it goes like this:

fb://page/(pageID)/addfan

If you need to get the pageID, replace "www" with "graph" in the Facebook url when you visit your page in a desktop browser and it will display the ID and other data.

Not only does this add them automatically, but it opens up the page in the FB app instead of the mobile browser.

As far as legality, I would assume as long as you put something like "Scan to like our page", you're in the clear. They know what they're getting into.

Thanks @Kit Ho for your answer. I used your code and found that I kept running into errors where my InputStream was always null and ClassNotFound exceptions when the JSONObject was being created. Here's my version of your code which does the trick for me:

import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import org.apache.commons.io.IOUtils;

import org.json.JSONObject;
public class JSONParsing {
    public static void main(String[] args) throws Exception {
        File f = new File("file.json");
        if (f.exists()){
            InputStream is = new FileInputStream("file.json");
            String jsonTxt = IOUtils.toString(is, "UTF-8");
            System.out.println(jsonTxt);
            JSONObject json = new JSONObject(jsonTxt);       
            String a = json.getString("1000");
            System.out.println(a);   
        }
    }
}

I found this answer to be enlightening about the difference between FileInputStream and getResourceAsStream. Hope this helps someone else too.

Can you use default android Crop functionality?

Here is my code

private void performCrop(Uri picUri) {
    try {
        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        // indicate image type and Uri
        cropIntent.setDataAndType(picUri, "image/*");
        // set crop properties here
        cropIntent.putExtra("crop", true);
        // indicate aspect of desired crop
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        // indicate output X and Y
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);
        // retrieve data on return
        cropIntent.putExtra("return-data", true);
        // start the activity - we handle returning in onActivityResult
        startActivityForResult(cropIntent, PIC_CROP);
    }
    // respond to users whose devices do not support the crop action
    catch (ActivityNotFoundException anfe) {
        // display an error message
        String errorMessage = "Whoops - your device doesn't support the crop action!";
        Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
        toast.show();
    }
}

declare:

final int PIC_CROP = 1;

at top.

In onActivity result method, writ following code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PIC_CROP) {
        if (data != null) {
            // get the returned data
            Bundle extras = data.getExtras();
            // get the cropped bitmap
            Bitmap selectedBitmap = extras.getParcelable("data");

            imgView.setImageBitmap(selectedBitmap);
        }
    }
}

It is pretty easy for me to implement and also shows darken areas.

Well, I am still stumped. So here is more code.

Before I leave my map, I call SaveLocation(myMapView,myMapController); This is what ends up calling my geocoding information.

But since getFromLocation can throw an IOException, I had to do the following to call SaveLocation

try
{
    SaveLocation(myMapView,myMapController);
}
catch (IOException e) 
{
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Then I have to change SaveLocation by saying it throws IOExceptions :

 public void SaveLocation(MapView mv, MapController mc) throws IOException{
    //I do this : 
    Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());   
    List myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
//...
    }

And it crashes every time.

With PYTHONPATH set as in your example, you should be able to do

python -m gmbx

-m option will make Python search for your module in paths Python usually searches modules in, including what you added to PYTHONPATH. When you run interpreter like python gmbx.py, it looks for particular file and PYTHONPATH does not apply.

Not as complicated as they say, check this you will not regret.

String sentence = "Check this answer and you can find the keyword with this code";
String search  = "keyword";

if ( sentence.toLowerCase().indexOf(search.toLowerCase()) != -1 ) {

   System.out.println("I found the keyword");

} else {

   System.out.println("not found");

}

You can change the toLowerCase() if you want.

As others have said, both == and .equals() work in most cases. The compile time certainty that you're not comparing completely different types of Objects that others have pointed out is valid and beneficial, however the particular kind of bug of comparing objects of two different compile time types would also be found by FindBugs (and probably by Eclipse/IntelliJ compile time inspections), so the Java compiler finding it doesn't add that much extra safety.

However:

1. The fact that == never throws NPE in my mind is a disadvantage of ==. There should hardly ever be a need for enum types to be null, since any extra state that you may want to express via null can just be added to the enum as an additional instance. If it is unexpectedly null, I'd rather have a NPE than == silently evaluating to false. Therefore I disagree with the it's safer at run-time opinion; it's better to get into the habit never to let enum values be @Nullable.
2. The argument that == is faster is also bogus. In most cases you'll call .equals() on a variable whose compile time type is the enum class, and in those cases the compiler can know that this is the same as == (because an enum's equals() method can not be overridden) and can optimize the function call away. I'm not sure if the compiler currently does this, but if it doesn't, and turns out to be a performance problem in Java overall, then I'd rather fix the compiler than have 100,000 Java programmers change their programming style to suit a particular compiler version's performance characteristics.
3. enums are Objects. For all other Object types the standard comparison is .equals(), not ==. I think it's dangerous to make an exception for enums because you might end up accidentally comparing Objects with == instead of equals(), especially if you refactor an enum into a non-enum class. In case of such a refactoring, the It works point from above is wrong. To convince yourself that a use of == is correct, you need to check whether value in question is either an enum or a primitive; if it was a non-enum class, it'd be wrong but easy to miss because the code would still compile. The only case when a use of .equals() would be wrong is if the values in question were primitives; in that case, the code wouldn't compile so it's much harder to miss. Hence, .equals() is much easier to identify as correct, and is safer against future refactorings.

I actually think that the Java language should have defined == on Objects to call .equals() on the left hand value, and introduce a separate operator for object identity, but that's not how Java was defined.

In summary, I still think the arguments are in favor of using .equals() for enum types.

I got the same error. In my case, I tried all of the above, but I couldn't get the result.

I finally realized that in my case, the reason for the error was that the certificate password was not entered or entered incorrectly. The error disappeared when I entered the password dynamically correctly. successful

The Good News is:

It's 100% working.

Just add something inside the script tag such as alert('voila!');. The right question you might want to ask perhaps, "Why didn't I see it in the DOM?".

Karl Swedberg has made a nice explanation to visitor's comment in jQuery API site. I don't want to repeat all his words, you can read directly there here (I found it hard to navigate through the comments there).

All of jQuery's insertion methods use a domManip function internally to clean/process elements before and after they are inserted into the DOM. One of the things the domManip function does is pull out any script elements about to be inserted and run them through an "evalScript routine" rather than inject them with the rest of the DOM fragment. It inserts the scripts separately, evaluates them, and then removes them from the DOM.

I believe that one of the reasons jQuery does this is to avoid "Permission Denied" errors that can occur in Internet Explorer when inserting scripts under certain circumstances. It also avoids repeatedly inserting/evaluating the same script (which could potentially cause problems) if it is within a containing element that you are inserting and then moving around the DOM.

The next thing is, I'll summarize what's the bad news by using .append() function to add a script.

And The Bad News is..

You can't debug your code.

I'm not joking, even if you add debugger; keyword between the line you want to set as breakpoint, you'll be end up getting only the call stack of the object without seeing the breakpoint on the source code, (not to mention that this keyword only works in webkit browser, all other major browsers seems to omit this keyword).

If you fully understand what your code does, than this will be a minor drawback. But if you don't, you will end up adding a debugger; keyword all over the place just to find out what's wrong with your (or my) code. Anyway, there's an alternative, don't forget that javascript can natively manipulate HTML DOM.

Workaround.

Use javascript (not jQuery) to manipulate HTML DOM

If you don't want to lose debugging capability, than you can use javascript native HTML DOM manipulation. Consider this example:

var script   = document.createElement("script");
script.type  = "text/javascript";
script.src   = "path/to/your/javascript.js";    // use this for linked script
script.text  = "alert('voila!');"               // use this for inline script
document.body.appendChild(script);

There it is, just like the old days isn't it. And don't forget to clean things up whether in the DOM or in the memory for all object that's referenced and not needed anymore to prevent memory leaks. You can consider this code to clean things up:

document.body.removechild(document.body.lastChild);
delete UnusedReferencedObjects; // replace UnusedReferencedObject with any object you created in the script you load.

The drawback from this workaround is that you may accidentally add a duplicate script, and that's bad. From here you can slightly mimic .append() function by adding an object verification before adding, and removing the script from the DOM right after it was added. Consider this example:

function AddScript(url, object){
    if (object != null){
        // add script
        var script   = document.createElement("script");
        script.type  = "text/javascript";
        script.src   = "path/to/your/javascript.js";
        document.body.appendChild(script);

        // remove from the dom
        document.body.removeChild(document.body.lastChild);
        return true;
    } else {
        return false;
    };
};

function DeleteObject(UnusedReferencedObjects) {
    delete UnusedReferencedObjects;
}

This way, you can add script with debugging capability while safe from script duplicity. This is just a prototype, you can expand for whatever you want it to be. I have been using this approach and quite satisfied with this. Sure enough I will never use jQuery .append() to add a script.

I noted that the accepted answer keeps adding int to the list and keeps checking them with if (!randomList.Contains(MyNumber)) and I think this doesn't scale well, especially if you keep asking for new numbers.

I would do the opposite.

1. Generate the list at startup, linearly
2. Get a random index from the list
3. Remove the found int from the list

This would require a slightly bit more time at startup, but will scale much much better.

public class RandomIntGenerator
{
    public Random a = new Random();
    private List<int> _validNumbers;

    private RandomIntGenerator(int desiredAmount, int start = 0)
    {
        _validNumbers = new List<int>();
        for (int i = 0; i < desiredAmount; i++)
            _validNumbers.Add(i + start);
    }

    private int GetRandomInt()
    {
        if (_validNumbers.Count == 0)
        {
            //you could throw an exception here
            return -1;
        }
        else
        {
            var nextIndex = a.Next(0, _validNumbers.Count - 1);
            var number    = _validNumbers[nextIndex];
            _validNumbers.RemoveAt(nextIndex);
            return number;
        }
    }
}

Try this using list comprehension:

import pandas as pd

df = pd.DataFrame(
    [p, p.team, p.passing_att, p.passer_rating()] for p in game.players.passing()
)

Custom Layout ( Slice ) :

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Paint.Style;
import android.graphics.Path;
import android.graphics.Point;

public class Slice extends View {

    Paint mPaint;

    Path mPath;

    public enum Direction {
        NORTH, SOUTH, EAST, WEST
    }

    public Slice(Context context) {
        super(context);

    }

    public Slice(Context context, AttributeSet attrs) {
        super(context, attrs);
        create();

    public void setColor(int color) {
        mPaint.setColor(color);
        invalidate();
    }

    private void create() {
        mPaint = new Paint();
        mPaint.setStyle(Style.FILL);
        mPaint.setColor(Color.RED);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        mPath = calculate(Direction.SOUTH);
        canvas.drawPath(mPath, mPaint);
    }

    private Path calculate(Direction direction) {
        Point p1 = new Point();
        p1.x = 0;
        p1.y = 0;

        Point p2 = null, p3 = null;

        int width = getWidth();

        if (direction == Direction.NORTH) {
            p2 = new Point(p1.x + width, p1.y);
            p3 = new Point(p1.x + (width / 2), p1.y - width);
        } else if (direction == Direction.SOUTH) {
            p2 = new Point(p1.x + width, p1.y);
            p3 = new Point(p1.x + (width / 2), p1.y + width);
        } else if (direction == Direction.EAST) {
            p2 = new Point(p1.x, p1.y + width);
            p3 = new Point(p1.x - width, p1.y + (width / 2));
        } else if (direction == Direction.WEST) {
            p2 = new Point(p1.x, p1.y + width);
            p3 = new Point(p1.x + width, p1.y + (width / 2));
        }

        Path path = new Path();
        path.moveTo(p1.x, p1.y);
        path.lineTo(p2.x, p2.y);
        path.lineTo(p3.x, p3.y);

        return path;
    }
}

Your Activity ( Example ) :

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;

public class Layout extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Slice mySlice = new Slice(getApplicationContext());
        mySlice.setBackgroundColor(Color.WHITE);
        setContentView(mySlice, new LinearLayout.LayoutParams(
                LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    }
}

Working Example :

Another absolutely simple Calculate function you may interested in ..

private Path Calculate(Point A, Point B, Point C) {
    Path Pencil = new Path();
    Pencil.moveTo(A.x, A.y);
    Pencil.lineTo(B.x, B.y);
    Pencil.lineTo(C.x, C.y);
    return Pencil;
}

raw_input is your helper here. From documentation -

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

So your code will basically look like this.

num_array = list()
num = raw_input("Enter how many elements you want:")
print 'Enter numbers in array: '
for i in range(int(num)):
    n = raw_input("num :")
    num_array.append(int(n))
print 'ARRAY: ',num_array

P.S: I have typed all this free hand. Syntax might be wrong but the methodology is correct. Also one thing to note is that, raw_input does not do any type checking, so you need to be careful...

For strings in general, is it always a good idea to use the copy attribute instead of retain?

Yes - in general always use the copy attribute.

This is because your NSString property can be passed an NSString instance or an NSMutableString instance, and therefore we can not really determine if the value being passed is an immutable or mutable object.

Is a "copied" property in any way less efficient than such a "retain-ed" property?

• If your property is being passed an NSString instance, the answer is "No" - copying is not less efficient than retain.
  (It's not less efficient because the NSString is smart enough to not actually perform a copy.)

• If your property is passed an NSMutableString instance then the answer is "Yes" - copying is less efficient than retain.
  (It's less efficient because an actual memory allocation and copy must occur, but this is probably a desirable thing.)

• Generally speaking a "copied" property has the potential to be less efficient - however through the use of the NSCopying protocol, it's possible to implement a class which is "just as efficient" to copy as it is to retain. NSString instances are an example of this.

Generally (not just for NSString), when should I use "copy" instead of "retain"?

You should always use copy when you don't want the internal state of the property changing without warning. Even for immutable objects - properly written immutable objects will handle copy efficiently (see next section regarding immutability and NSCopying).

There may be performance reasons to retain objects, but it comes with a maintenance overhead - you must manage the possibility of the internal state changing outside your code. As they say - optimize last.

But, I wrote my class to be immutable - can't I just "retain" it?

No - use copy. If your class is really immutable then it's best practice to implement the NSCopying protocol to make your class return itself when copy is used. If you do this:

• Other users of your class will gain the performance benefits when they use copy.
• The copy annotation makes your own code more maintainable - the copy annotation indicates that you really don't need to worry about this object changing state elsewhere.

SmtpClient MyMail = new SmtpClient();
MailMessage MyMsg = new MailMessage();
MyMail.Host = "mail.eraygan.com";
MyMsg.Priority = MailPriority.High;
MyMsg.To.Add(new MailAddress(Mail));
MyMsg.Subject = Subject;
MyMsg.SubjectEncoding = Encoding.UTF8;
MyMsg.IsBodyHtml = true;
MyMsg.From = new MailAddress("username", "displayname");
MyMsg.BodyEncoding = Encoding.UTF8;
MyMsg.Body = Body;
MyMail.UseDefaultCredentials = false;
NetworkCredential MyCredentials = new NetworkCredential("username", "password");
MyMail.Credentials = MyCredentials;
MyMail.Send(MyMsg);

If you're like me and tried a few of these methods and are stuck at the point that you have the control in the toolbox and can draw it on the form but it disappears from the form and puts it down in the components, then simply edit the designer and add the following in the appropriate area of InitializeComponent() to make it visible:

this.Controls.Add(this.reportViewer1);

or

[ContainerControl].Controls.Add(this.reportViewer1);

You'll also need to make adjustments to the location and size manually after you've added the control.

Not a great answer for sure, but if you're stuck and just need to get work done for now until you have more time to figure it out, it should help.

This works for Swift 5:

self.navigationItem.backBarButtonItem?.title = ""

Please note it will be effective for the next pushed view controller not the current one on the display, that's why it's very confusing!

Also, check the storyboard and select the navigation item of the previous view controller then type something in the Back Button (Inspector).

You can transition background-image. Use the CSS below on the img element:

-webkit-transition: background-image 0.2s ease-in-out;
transition: background-image 0.2s ease-in-out;

This is supported natively by Chrome, Opera and Safari. Firefox hasn't implemented it yet (bugzil.la). Not sure about IE.

$('div#someID').datepicker({
   onSelect: function(dateText, inst) { alert(dateText); }
});

you must bind it to input element only

A lot of these answers are pretty old, so I thought I would update with a solution that I think is helpful.

Our issue was similar to OP's, we upgraded 32 bit XP machines to 64 bit windows 7 and our application software that uses a 32 bit ODBC driver stopped being able to write to our database.

Turns out, there are two ODBC Data Source Managers, one for 32 bit and one for 64 bit. So I had to run the 32 bit version which is found in C:\Windows\SysWOW64\odbcad32.exe. Inside the ODBC Data Source Manager, I was able to go to the System DSN tab and Add my driver to the list using the Add button. (You can check the Drivers tab to see a list of the drivers you can add, if your driver isn't in this list then you may need to install it).

The next issue was the software that we ran was compiled to use 'Any CPU'. This would see the operating system was 64 bit, so it would look at the 64 bit ODBC Data Sources. So I had to force the program to compile as an x86 program, which then tells it to look at the 32 bit ODBC Data Sources. To set your program to x86, in Visual Studio go to your project properties and under the build tab at the top there is a platform drop down list, and choose x86. If you don't have the source code and can't compile the program as x86, you might be able to right click the program .exe and go to the compatibility tab and choose a compatibility that works for you.

Once I had the drivers added and the program pointing to the right drivers, everything worked like it use to. Hopefully this helps anyone working with older software.

I tried use [disabled]="!editmode" but it not work in my case.

This is my solution [disabled]="!editmode ? 'disabled': null" , I share for whom concern.

<button [disabled]="!editmode ? 'disabled': null" 
    (click)='loadChart()'>
            <div class="btn-primary">Load Chart</div>
    </button>

Offering a quick answer for people using Ionic. I need to show a tooltip only once so I used the $localStorage to achieve this. This is for playing a track, so when they push play, it shows the tooltip once.

$scope.storage = $localStorage; //connects an object to $localstorage

$scope.storage.hasSeenPopup = "false";  // they haven't seen it


$scope.showPopup = function() {  // popup to tell people to turn sound on

    $scope.data = {}
    // An elaborate, custom popup
    var myPopup = $ionicPopup.show({
        template: '<p class="popuptext">Turn Sound On!</p>',
        cssClass: 'popup'

    });        
    $timeout(function() {
        myPopup.close(); //close the popup after 3 seconds for some reason
    }, 2000);
    $scope.storage.hasSeenPopup = "true"; // they've now seen it

};

$scope.playStream = function(show) {
    PlayerService.play(show);

    $scope.audioObject = audioObject; // this allow for styling the play/pause icons

    if ($scope.storage.hasSeenPopup === "false"){ //only show if they haven't seen it.
        $scope.showPopup();
    }
}

By default, Windows makes the root of each drive available (provided you've got Administrator privileges) as (e.g.) \\server\c$. These are known as Administrative Shares.

This works in MAC for me

sed -i.bak -e 's/regex/xregex/g' input.txt sed -i.bak -e 's/qregex/\'$'\nregex/g' input.txt

Dono whether its perfect one...

With the arrival of the HTTPClient API, not only was the Http API replaced, but a new one was added, the HttpInterceptor API.

AFAIK one of its goals is to add default behavior to all the HTTP outgoing requests and incoming responses.

So assumming that you want to add a default error handling behavior, adding .catch() to all of your possible http.get/post/etc methods is ridiculously hard to maintain.

This could be done in the following way as example using a HttpInterceptor:

import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest, HttpErrorResponse, HTTP_INTERCEPTORS } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { _throw } from 'rxjs/observable/throw';
import 'rxjs/add/operator/catch';

/**
 * Intercepts the HTTP responses, and in case that an error/exception is thrown, handles it
 * and extract the relevant information of it.
 */
@Injectable()
export class ErrorInterceptor implements HttpInterceptor {
    /**
     * Intercepts an outgoing HTTP request, executes it and handles any error that could be triggered in execution.
     * @see HttpInterceptor
     * @param req the outgoing HTTP request
     * @param next a HTTP request handler
     */
    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        return next.handle(req)
            .catch(errorResponse => {
                let errMsg: string;
                if (errorResponse instanceof HttpErrorResponse) {
                    const err = errorResponse.message || JSON.stringify(errorResponse.error);
                    errMsg = `${errorResponse.status} - ${errorResponse.statusText || ''} Details: ${err}`;
                } else {
                    errMsg = errorResponse.message ? errorResponse.message : errorResponse.toString();
                }
                return _throw(errMsg);
            });
    }
}

/**
 * Provider POJO for the interceptor
 */
export const ErrorInterceptorProvider = {
    provide: HTTP_INTERCEPTORS,
    useClass: ErrorInterceptor,
    multi: true,
};

// app.module.ts

import { ErrorInterceptorProvider } from 'somewhere/in/your/src/folder';

@NgModule({
   ...
   providers: [
    ...
    ErrorInterceptorProvider,
    ....
   ],
   ...
})
export class AppModule {}

Some extra info for OP: Calling http.get/post/etc without a strong type isn't an optimal use of the API. Your service should look like this:

// These interfaces could be somewhere else in your src folder, not necessarily in your service file
export interface FooPost {
 // Define the form of the object in JSON format that your 
 // expect from the backend on post
}

export interface FooPatch {
 // Define the form of the object in JSON format that your 
 // expect from the backend on patch
}

export interface FooGet {
 // Define the form of the object in JSON format that your 
 // expect from the backend on get
}

@Injectable()
export class DataService {
    baseUrl = 'http://localhost'
    constructor(
        private http: HttpClient) {
    }

    get(url, params): Observable<FooGet> {

        return this.http.get<FooGet>(this.baseUrl + url, params);
    }

    post(url, body): Observable<FooPost> {
        return this.http.post<FooPost>(this.baseUrl + url, body);
    }

    patch(url, body): Observable<FooPatch> {
        return this.http.patch<FooPatch>(this.baseUrl + url, body);
    }
}

Returning Promises from your service methods instead of Observables is another bad decision.

And an extra piece of advice: if you are using TYPEscript, then start using the type part of it. You lose one of the biggest advantages of the language: to know the type of the value that you are dealing with.

If you want a, in my opinion, good example of an angular service, take a look at the following gist.

You have to create either another page or generic handler with the code to generate your pdf. Then that event gets triggered and the person is redirected to that page.

Assuming you can use integrated security, you can remove the user id and pass:

$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True;"

Commenting here as this seems to be the most popular answer on the subject for searching for files whilst excluding certain directories in powershell.

To avoid issues with post filtering of results (i.e. avoiding permission issues etc), I only needed to filter out top level directories and that is all this example is based on, so whilst this example doesn't filter child directory names, it could very easily be made recursive to support this, if you were so inclined.

Quick breakdown of how the snippet works

$folders << Uses Get-Childitem to query the file system and perform folder exclusion

$file << The pattern of the file I am looking for

foreach << Iterates the $folders variable performing a recursive search using the Get-Childitem command

$folders = Get-ChildItem -Path C:\ -Directory -Name -Exclude Folder1,"Folder 2"
$file = "*filenametosearchfor*.extension"

foreach ($folder in $folders) {
   Get-Childitem -Path "C:/$folder" -Recurse -Filter $file | ForEach-Object { Write-Output $_.FullName }
}

I came across this issue yesterday, but none of the solutions here worked exactly, however they did point me in the right direction.

Our application is a workflow tool written in C# and, overly simplified, has several stored procedures on the database, as well as a table of metadata about each parameter used by each stored procedure (name, order, data type, size, etc), allowing us to create as many new stored procedures as we need without having to change the C#.

Analysis of the problem showed that our code was setting all the correct parameters on the SqlCommand object, however once it was executed, it threw the same error as the OP got.

Further analysis revealed that some parameters had a value of null. I therefore must draw the conclusion that SqlCommand objects ignore any SqlParameter object in their .Parameters collection with a value of null.

There are two solutions to this problem that I found.

1. In our stored procedures, give a default value to each parameter, so from @Parameter int to @Parameter int = NULL (or some other default value as required).

2. In our code that generates the individual SqlParameter objects, assigning DBNull.Value instead of null where the intended value is a SQL NULL does the trick.

The original coder has moved on and the code was originally written with Solution 1 in mind, and having weighed up the benefits of both, I think I'll stick with Solution 1. It's much easier to specify a default value for a specific stored procedure when writing it, rather than it always being NULL as defined in the code.

Hope that helps someone.

Update (using renderer):

Note that the original Renderer service has now been deprecated in favor of Renderer2

as on Renderer2 official doc.

Furthermore, as pointed out by @GünterZöchbauer:

Actually using ElementRef is just fine. Also using ElementRef.nativeElement with Renderer2 is fine. What is discouraged is accessing properties of ElementRef.nativeElement.xxx directly.

You can achieve this by using elementRef as well as by ViewChild. however it's not recommendable to use elementRef due to:

• security issue
• tight coupling

as pointed out by official ng2 documentation.

1. Using elementRef (Direct Access):

export class MyComponent {    
constructor (private _elementRef : ElementRef) {
 this._elementRef.nativeElement.querySelector('textarea').focus();
 }
}

2. Using ViewChild (better approach):

<textarea  #tasknote name="tasknote" [(ngModel)]="taskNote" placeholder="{{ notePlaceholder }}" 
style="background-color: pink" (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} </textarea> // <-- changes id to local var


export class MyComponent implements AfterViewInit {
  @ViewChild('tasknote') input: ElementRef;

   ngAfterViewInit() {
    this.input.nativeElement.focus();

  }
}

3. Using renderer:

export class MyComponent implements AfterViewInit {
      @ViewChild('tasknote') input: ElementRef;
         constructor(private renderer: Renderer2){           
          }

       ngAfterViewInit() {
       //using selectRootElement instead of depreaced invokeElementMethod
       this.renderer.selectRootElement(this.input["nativeElement"]).focus();
      }

    }

It's not impossible without CSS. For example as a list item:

<li style="border-bottom: 1px dashed"><!--content --></li>

In my humble opinion, I understand this question in this way:

[CASE 1] When you start an absolute-import like

python -m test_A.test

or

import test_A.test

or

from test_A import test

you're actually setting the import-anchor to be test_A, in other word, top-level package is test_A . So, when we have test.py do from ..A import xxx, you are escaping from the anchor, and Python does not allow this.

[CASE 2] When you do

python -m package.test_A.test

or

from package.test_A import test

your anchor becomes package, so package/test_A/test.py doing from ..A import xxx does not escape the anchor(still inside package folder), and Python happily accepts this.

In short:

• Absolute-import changes current anchor (=redefines what is the top-level package);
• Relative-import does not change the anchor but confines to it.

Furthermore, we can use full-qualified module name(FQMN) to inspect this problem.

Check FQMN in each case:

• [CASE2] test.__name__ = package.test_A.test
• [CASE1] test.__name__ = test_A.test

So, for CASE2, an from .. import xxx will result in a new module with FQMN=package.xxx, which is acceptable.

While for CASE1, the .. from within from .. import xxx will jump out of the starting node(anchor) of test_A, and this is NOT allowed by Python.

The following approach worked in Angular 5 CLI.

For sake of simplicity, I used similar d3gauge.js demo created and provided by oliverbinns - which you may easily find on Github.

So first, I simply created a new folder named externalJS on same level as the assets folder. I then copied the 2 following .js files.

• d3.v3.min.js
• d3gauge.js

I then made sure to declare both linked directives in main index.html

<script src="./externalJS/d3.v3.min.js"></script>
<script src="./externalJS/d3gauge.js"></script>

I then added a similar code in a gauge.component.ts component as followed:

import { Component, OnInit } from '@angular/core';

declare var d3gauge:any; <----- !
declare var drawGauge: any; <-----!

@Component({
  selector: 'app-gauge',
  templateUrl: './gauge.component.html'
})

export class GaugeComponent implements OnInit {
   constructor() { }

   ngOnInit() {
      this.createD3Gauge();
   }

   createD3Gauge() { 
      let gauges = []
      document.addEventListener("DOMContentLoaded", function (event) {      
      let opt = {
         gaugeRadius: 160,
         minVal: 0,
         maxVal: 100,
         needleVal: Math.round(30),
         tickSpaceMinVal: 1,
         tickSpaceMajVal: 10,
         divID: "gaugeBox",
         gaugeUnits: "%"
    } 

    gauges[0] = new drawGauge(opt);
    });
 }

}

and finally, I simply added a div in corresponding gauge.component.html

<div id="gaugeBox"></div>

et voilà ! :)

Probably something like this? (UNTESTED)

Sub Sample()
    Dim strWB4, strMyMacro
    strMyMacro = "Sheet1.my_macro_name"

    '
    '~~> Rest of Code
    '

    'loop through the folder and get the file names
    For Each Fil In FLD.Files
        Set x4WB = x1.Workbooks.Open(Fil)
        x4WB.Application.Visible = True

        x1.Run strMyMacro

        x4WB.Close

        Do Until IsWorkBookOpen(Fil) = False
            DoEvents
        Loop
    Next

    '
    '~~> Rest of Code
    '
End Sub

'~~> Function to check if the file is open
Function IsWorkBookOpen(FileName As String)
    Dim ff As Long, ErrNo As Long

    On Error Resume Next
    ff = FreeFile()
    Open FileName For Input Lock Read As #ff
    Close ff
    ErrNo = Err
    On Error GoTo 0

    Select Case ErrNo
    Case 0:    IsWorkBookOpen = False
    Case 70:   IsWorkBookOpen = True
    Case Else: Error ErrNo
    End Select
End Function

I ran into the same problem and then remembered something wonky about a legacy project I was working on and how they handled this issue. I didn't understand it at the time and didn't really care until I ran into the problem myself

var date = '2014-01-02T00:00:00.000Z'
date = date.substring(0,10).split('-')
date = date[1] + '-' + date[2] + '-' + date[0]

new Date(date) #Thu Jan 02 2014 00:00:00 GMT-0600

For whatever reason passing the date in as '01-02-2014' sets the timezone to zero and ignores the user's timezone. This may be a fluke in the Date class but it existed some time ago and exists today. And it seems to work cross-browser. Try it for yourself.

This code is implemented in a global project where timezones matter a lot but the person looking at the date did not care about the exact moment it was introduced.

var a=[];
a.push({
 name_a:"abc",
 b:[]
});

a.b.push({

No need to update gradle for making release application in Android studio.If you were eclipse user then it will be so easy for you. If you are new then follow the steps

1: Go to the "Build" at the toolbar section. 2: Choose "Generate Signed APK..." option.

3:fill opened form and go next 4 :if you already have .keystore or .jks then choose that file enter your password and alias name and respective password. 5: Or don't have .keystore or .jks file then click on Create new... button as shown on pic 1 then fill the form.

Above process was to make build manually. If You want android studio to automatically Signing Your App

In Android Studio, you can configure your project to sign your release APK automatically during the build process:

On the project browser, right click on your app and select Open Module Settings. On the Project Structure window, select your app's module under Modules. Click on the Signing tab. Select your keystore file, enter a name for this signing configuration (as you may create more than one), and enter the required information. Figure 4. Create a signing configuration in Android Studio.

Click on the Build Types tab. Select the release build. Under Signing Config, select the signing configuration you just created. Figure 5. Select a signing configuration in Android Studio.

String x = JComboBox.getSelectedItem().toString();

will convert any value weather it is Integer, Double, Long, Short into text on the other hand,

String x = String.valueOf(JComboBox.getSelectedItem());

will avoid null values, and convert the selected item from object to string

Please use this

window.open("url","_self"); 

• The first parameter "url" is full path of which page you want to open.
• The second parameter "_self", It's used for open page in same tab. You want open the page in another tab please use "_blank".

I've written a post about this once: Resolving circular dependencies in c++

The basic technique is to decouple the classes using interfaces. So in your case:

//Printer.h
class Printer {
public:
    virtual Print() = 0;
}

//A.h
#include "Printer.h"
class A: public Printer
{
    int _val;
    Printer *_b;
public:

    A(int val)
        :_val(val)
    {
    }

    void SetB(Printer *b)
    {
        _b = b;
        _b->Print();
    }

    void Print()
    {
        cout<<"Type:A val="<<_val<<endl;
    }
};

//B.h
#include "Printer.h"
class B: public Printer
{
    double _val;
    Printer* _a;
public:

    B(double val)
        :_val(val)
    {
    }

    void SetA(Printer *a)
    {
        _a = a;
        _a->Print();
    }

    void Print()
    {
        cout<<"Type:B val="<<_val<<endl;
    }
};

//main.cpp
#include <iostream>
#include "A.h"
#include "B.h"

int main(int argc, char* argv[])
{
    A a(10);
    B b(3.14);
    a.Print();
    a.SetB(&b);
    b.Print();
    b.SetA(&a);
    return 0;
}

Due to this question is old. First, I'm sorry about this.

The question is about number xxx.xx but in case that it is x,xxx.xxxxx or difference decimal separator such as xxxx,xxxx this can be harder to find and remove zero digits from decimal value.

/**
 * Remove zero digits from decimal value.
 * 
 * @param string|int|float $number The number can be any format, any where use in the world such as 123, 1,234.56, 1234.56789, 12.345,67, -98,765.43
 * @param string The decimal separator. You have to set this parameter to exactly what it is. For example: in Europe it is mostly use "," instead of ".".
 * @return string Return removed zero digits from decimal value.
 */
function removeZeroDigitsFromDecimal($number, $decimal_sep = '.')
{
    $explode_num = explode($decimal_sep, $number);
    if (is_array($explode_num) && isset($explode_num[count($explode_num)-1]) && intval($explode_num[count($explode_num)-1]) === 0) {
        unset($explode_num[count($explode_num)-1]);
        $number = implode($decimal_sep, $explode_num);
    }
    unset($explode_num);
    return (string) $number;
}

And here is the code for test.

$numbers = [
    1234,// 1234
    -1234,// -1234
    '12,345.67890',// 12,345.67890

    '-12345.000000',// -12345
    '12,345.000000',// 12,345
    '-12,345.000000000',// -12,345
];
foreach ($numbers as $number) {
    var_dump(removeZeroDigitsFromDecimal($number));
}


echo '<hr>'."\n\n\n";


$numbers = [
    1234,// 12324

    '12345,000000',// 12345
    '-12345,000000',// -12345
    '12.345,000000',// 12.345
    '-12.345,000000000',// -12.345
    '-12.345,000000,000',// -12.345,000000 STRANGE!! but also work.
];
foreach ($numbers as $number) {
    var_dump(removeZeroDigitsFromDecimal($number, ','));
}

You simply want the File.GetLastWriteTime static method.

Example:

var lastModified = System.IO.File.GetLastWriteTime("C:\foo.bar");

Console.WriteLine(lastModified.ToString("dd/MM/yy HH:mm:ss"));

Note however that in the rare case the last-modified time is not updated by the system when writing to the file (this can happen intentionally as an optimisation for high-frequency writing, e.g. logging, or as a bug), then this approach will fail, and you will instead need to subscribe to file write notifications from the system, constantly listening.

I have a slightly different perspective on the difference between a DATETIME and a TIMESTAMP. A DATETIME stores a literal value of a date and time with no reference to any particular timezone. So, I can set a DATETIME column to a value such as '2019-01-16 12:15:00' to indicate precisely when my last birthday occurred. Was this Eastern Standard Time? Pacific Standard Time? Who knows? Where the current session time zone of the server comes into play occurs when you set a DATETIME column to some value such as NOW(). The value stored will be the current date and time using the current session time zone in effect. But once a DATETIME column has been set, it will display the same regardless of what the current session time zone is.

A TIMESTAMP column on the other hand takes the '2019-01-16 12:15:00' value you are setting into it and interprets it in the current session time zone to compute an internal representation relative to 1/1/1970 00:00:00 UTC. When the column is displayed, it will be converted back for display based on whatever the current session time zone is. It's a useful fiction to think of a TIMESTAMP as taking the value you are setting and converting it from the current session time zone to UTC for storing and then converting it back to the current session time zone for displaying.

If my server is in San Francisco but I am running an event in New York that starts on 9/1/1029 at 20:00, I would use a TIMESTAMP column for holding the start time, set the session time zone to 'America/New York' and set the start time to '2009-09-01 20:00:00'. If I want to know whether the event has occurred or not, regardless of the current session time zone setting I can compare the start time with NOW(). Of course, for displaying in a meaningful way to a perspective customer, I would need to set the correct session time zone. If I did not need to do time comparisons, then I would probably be better off just using a DATETIME column, which will display correctly (with an implied EST time zone) regardless of what the current session time zone is.

TIMESTAMP LIMITATION

The TIMESTAMP type has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC and so it may not usable for your particular application. In that case you will have to use a DATETIME type. You will, of course, always have to be concerned that the current session time zone is set properly whenever you are using this type with date functions such as NOW().

df = pd.read_csv('somefile.csv', low_memory=False)

This should solve the issue. I got exactly the same error, when reading 1.8M rows from a CSV.

I was having a similar problem. (No problems training with GradientDescent optimizer, but error raised when using to Adam Optimizer, or any other optimizer with its own variables)

Changing to an interactive session solved this problem for me.

sess = tf.Session()

into

sess = tf.InteractiveSession()

[Update: as of Go 1.8, GOPATH defaults to $HOME/go, but you may still find this useful if you want to understand the GOPATH layout, customize it, etc.]

The official Go site discusses GOPATH and how to lay out a workspace directory.

export GOPATH="$HOME/your-workspace-dir/" -- run it in your shell, then add it to ~/.bashrc or equivalent so it will be set for you in the future. Go will install packages under src/, bin/, and pkg/, subdirectories there. You'll want to put your own packages somewhere under $GOPATH/src, like $GOPATH/src/github.com/myusername/ if you want to publish to GitHub. You'll also probably want export PATH=$PATH:$GOPATH/bin in your .bashrc so you can run compiled programs under $GOPATH.

Optionally, via Rob Pike, you can also set CDPATH so it's faster to cd to package dirs in bash: export CDPATH=.:$GOPATH/src/github.com:$GOPATH/src/golang.org/x means you can just type cd net/html instead of cd $GOPATH/src/golang.org/x/net/html.

Keith Rarick notes you can set GOPATH=$HOME to put Go's src/, pkg/ and bin/ directories right under your homedir. That can be nice (for instance, you might already have $HOME/bin in your path) but of course some folks use multiple workspaces, etc.

According to PEP8, long lines should be placed in parentheses. When using parentheses, the lines can be broken up without using backslashes. You should also try to put the line break after boolean operators.

Further to this, if you're using a code style check such as pycodestyle, the next logical line needs to have different indentation to your code block.

For example:

if (abcdefghijklmnopqrstuvwxyz > some_other_long_identifier and
        here_is_another_long_identifier != and_finally_another_long_name):
    # ... your code here ...
    pass

In addition to the pure javascript answers above, You can use jQuery text method as following:

$('#myspan').text('newtext');

If you need to extend the answer to get/change html content of a span or div elements, you can do this:

$('#mydiv').html('<strong>new text</strong>');

Am going to try and add value to this very good question and to build on @BrittonKerin's question in one of the comments under @David Wolever's fantastic answer. Wanted to share here because I had the same challenge as @BrittonKerin and I got something working (i.e. just want to run a piece of code only IF the table doesn't exist).

        # for completeness lets do the routine thing of connections and cursors
        conn = sqlite3.connect(db_file, timeout=1000) 

        cursor = conn.cursor() 

        # get the count of tables with the name  
        tablename = 'KABOOM' 
        cursor.execute("SELECT count(name) FROM sqlite_master WHERE type='table' AND name=? ", (tablename, ))

        print(cursor.fetchone()) # this SHOULD BE in a tuple containing count(name) integer.

        # check if the db has existing table named KABOOM
        # if the count is 1, then table exists 
        if cursor.fetchone()[0] ==1 : 
            print('Table exists. I can do my custom stuff here now.... ')
            pass
        else: 
           # then table doesn't exist. 
           custRET = myCustFunc(foo,bar) # replace this with your custom logic

Download Notepad++ (notepad-plus-plus.org) it opens nearly any file format and recognizes breaks, comments and does all the same color coding as the original language formatting.

This answer goes over the exact same thing (although for angular) -- it is a CORS issue.

One quick fix is to modify each POST request by specifying one of the 'Content-Type' header values which will not trigger a "preflight". These types are:

• application/x-www-form-urlencoded
• multipart/form-data
• text/plain

ANYTHING ELSE triggers a preflight.

For example:

$.ajax({
   url: 'http://api.example.com/users/get',
   type: 'POST',
   headers: {
      'name-api-key':'ewf45r4435trge',
      'Content-Type':'application/x-www-form-urlencoded'
   },
   data: {
      'uid':36,
   },
   success: function(data) {
      console.log(data);
   }
});

I'm using Ubuntu

after reading many of answers, none of them can solve the problem, even if I already added SSH key to my git account, and try test it using ssh -T [email protected] and it said Welcome <my username>, but it still kept telling me that I don't have access rights. Then I found the reason:

Normally if you're not root user, it will require you to run with sudo for every git command.

when running sudo git clone <SSH....> (for example). it will be executed under root permission, but accidentally when create SSH key I run it as normal user and I save the key in ~/.ssh/id_rsa, it resolves the absolute path /home/username/.ssh/id_rsa. And when doing sudo git clone ... it looks for SSH key in /root/.ssh/id_rsa

Why I can sure about this. To see where git looks for your SSH key. Run this command: sudo GIT_TRACE=1 GIT_SSH_COMMAND="ssh -vvv" git clone <your repository in SSH>. It will show you where it looks for your SSH key.

So the SOLUTION I suggest is:

Re-creating your SSH key (follow this instruction), BUT run sudo su at the very first step, then you'll should be fine.

Use standard Java I/O. Use Environment.getExternalStorageDirectory() to get to the root of external storage (which, on some devices, is an SD card).

cond? statementA: statementB

Equals to:

if (cond)
    statementA
else
    statementB

For your case, you may just delete all "if". If you totally use if-else instead of ?:. Don't mix them together.

At the risk of irritating you;

You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.

Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.

What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.

It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.

In short, it's just unnecessarily conflating the matter when there is no need to.

Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().

Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)

adding to above comment, in which people are suggesting to prune system like clear dangling volumes, images, exit containers etc., Sometime your app become culprit, it generated too much logs in a small time and if you using empty directy volume (local volumes) this fill the /var partitions. In that case I found below command very interesting to figure out, what is consuming space on my /var partition disk.

du -ahx /var/lib | sort -rh | head -n 30

This command will list top 30, which is consuming most space on a single disk. Means if you are using external storage with your containers, it consumes a lot of time to run du command. This command will not count mount volumes. And is much faster. You will get the exact directories/files which are consuming space. Then you can go to those directories and check which files are useful or not. if these files are required then you can move them to some persistent storage by making change in app to use persistent storage for that location or change location of that files. And for rest you can clear them.

Answer: 09 December 2015

Personally, I found the accepted answer both concise (good) and terse (bad). Appreciate this statement might be subjective, so please read this answer and see if you agree or disagree

The example given in the question was something like Ruby's:

x.times do |i|
  do_stuff(i)
end

Expressing this in JS using below would permit:

times(x)(doStuff(i));

Here is the code:

let times = (n) => {
  return (f) => {
    Array(n).fill().map((_, i) => f(i));
  };
};

That's it!

Simple example usage:

let cheer = () => console.log('Hip hip hooray!');

times(3)(cheer);

//Hip hip hooray!
//Hip hip hooray!
//Hip hip hooray!

Alternatively, following the examples of the accepted answer:

let doStuff = (i) => console.log(i, ' hi'),
  once = times(1),
  twice = times(2),
  thrice = times(3);

once(doStuff);
//0 ' hi'

twice(doStuff);
//0 ' hi'
//1 ' hi'

thrice(doStuff);
//0 ' hi'
//1 ' hi'
//2 ' hi'

Side note - Defining a range function

A similar / related question, that uses fundamentally very similar code constructs, might be is there a convenient Range function in (core) JavaScript, something similar to underscore's range function.

Create an array with n numbers, starting from x

Underscore

_.range(x, x + n)

ES2015

Couple of alternatives:

Array(n).fill().map((_, i) => x + i)

Array.from(Array(n), (_, i) => x + i)

Demo using n = 10, x = 1:

> Array(10).fill().map((_, i) => i + 1)
// [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]

> Array.from(Array(10), (_, i) => i + 1)
// [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]

In a quick test I ran, with each of the above running a million times each using our solution and doStuff function, the former approach (Array(n).fill()) proved slightly faster.

Sub Button167_Click()
 If ThisWorkbook.Worksheets(1).Shapes("Check Box 1").OLEFormat.Object.Value = 1 Then
 Range("Y12").Value = 1
 Else
 Range("Y12").Value = 0
 End If
End Sub

1 is checked, -4146 is unchecked, 2 is mixed (grey box)

When you use VARIABLE = value, if value is actually a reference to another variable, then the value is only determined when VARIABLE is used. This is best illustrated with an example:

VAL = foo
VARIABLE = $(VAL)
VAL = bar

# VARIABLE and VAL will both evaluate to "bar"

When you use VARIABLE := value, you get the value of value as it is now. For example:

VAL = foo
VARIABLE := $(VAL)
VAL = bar

# VAL will evaluate to "bar", but VARIABLE will evaluate to "foo"

Using VARIABLE ?= val means that you only set the value of VARIABLE if VARIABLE is not set already. If it's not set already, the setting of the value is deferred until VARIABLE is used (as in example 1).

VARIABLE += value just appends value to VARIABLE. The actual value of value is determined as it was when it was initially set, using either = or :=.

Note that the bb.array() doesn't honor the byte-buffers position, and might be even worse if the bytebuffer you are working on is a slice of some other buffer.

I.e.

byte[] test = "Hello World".getBytes("Latin1");
ByteBuffer b1 = ByteBuffer.wrap(test);
byte[] hello = new byte[6];
b1.get(hello); // "Hello "
ByteBuffer b2 = b1.slice(); // position = 0, string = "World"
byte[] tooLong = b2.array(); // Will NOT be "World", but will be "Hello World".
byte[] world = new byte[5];
b2.get(world); // world = "World"

Which might not be what you intend to do.

If you really do not want to copy the byte-array, a work-around could be to use the byte-buffer's arrayOffset() + remaining(), but this only works if the application supports index+length of the byte-buffers it needs.

I'm with a similar problem, but, in filenames of a file I'm compressing with apache commons. So, i resolved it with this command:

convmv --notest -f cp1252 -t utf8 * -r

it works very well for me. Hope it help anyone ;)

This is how I calculated the real dimensions for the first letter (you can change the method header to suit your needs, i.e. instead of char[] use String):

private void calculateTextSize(char[] text, PointF outSize) {
    // use measureText to calculate width
    float width = mPaint.measureText(text, 0, 1);

    // use height from getTextBounds()
    Rect textBounds = new Rect();
    mPaint.getTextBounds(text, 0, 1, textBounds);
    float height = textBounds.height();
    outSize.x = width;
    outSize.y = height;
}

Note that I'm using TextPaint instead of the original Paint class.

If I first install BLAS, LAPACK and GCC Fortran as system packages (I'm using Arch Linux), I can get SciPy installed with:

pip install scipy

Here's the working version of the code in question (requires at least version Matplotlib 1.1.0 from 2011-11-14):

import numpy as np
import matplotlib.pyplot as plt

plt.axis([0, 10, 0, 1])

for i in range(10):
    y = np.random.random()
    plt.scatter(i, y)
    plt.pause(0.05)

plt.show()

Note some of the changes:

1. Call plt.pause(0.05) to both draw the new data and it runs the GUI's event loop (allowing for mouse interaction).

I am guessing that you want to prettify the JSON output. That could be achieved using python:

curl http://localhost:8880/test.json | python -mjson.tool > out.json

While looking at the same problem, I found an example

<style type="text/css">
#topright {
    position: absolute;
    right: 0;
    top: 0;
    display: block;
    height: 125px;
    width: 125px;
    background: url(TRbanner.gif) no-repeat;
    text-indent: -999em;
    text-decoration: none;
}
</style>

<a id="topright" href="#" title="TopRight">Top Right Link Text</a>

The trick here is to create a small, (I used GIMP) a PNG (or GIF) that has a transparent background, (and then just delete the opposite bottom corner.)

you can do:

for k in ax.get_xmajorticklabels():
    if some-condition:
        k.set_color(any_colour_you_like)

draw()

The percent symbol means: any host, including remote and local connections.

The localhost allows only local connections.

(so to start off, if you don't need remote connections to your database, you can get rid of the appuser@'%' user right away)

So, yes, they are overlapping, but...

...there is a reason for setting both types of accounts, this is explained in the mysql docs: http://dev.mysql.com/doc/refman/5.7/en/adding-users.html.

If you have an have an anonymous user on your localhost, which you can spot with:

select Host from mysql.user where User='' and Host='localhost';

and if you just create the user appuser@'%' (and you not the appuser@'localhost'), then when the appuser mysql user connects from the local host, the anonymous user account is used (it has precedence over your appuser@'%' user).

And the fix for this is (as one can guess) to create the appuser@'localhost' (which is more specific that the local host anonymous user and will be used if your appuser connects from the localhost).

Definitely use Pyglet for this. It's kind of a large package, but it is pure python with no extension modules. That will definitely be the easiest for deployment. It's also got great format and codec support.

You can build your HttpContent using the combination of JObject to avoid and JProperty and then call ToString() on it when building the StringContent:

        /*{
          "agent": {                             
            "name": "Agent Name",                
            "version": 1                                                          
          },
          "username": "Username",                                   
          "password": "User Password",
          "token": "xxxxxx"
        }*/

        JObject payLoad = new JObject(
            new JProperty("agent", 
                new JObject(
                    new JProperty("name", "Agent Name"),
                    new JProperty("version", 1)
                    ),
                new JProperty("username", "Username"),
                new JProperty("password", "User Password"),
                new JProperty("token", "xxxxxx")    
                )
            );

        using (HttpClient client = new HttpClient())
        {
            var httpContent = new StringContent(payLoad.ToString(), Encoding.UTF8, "application/json");

            using (HttpResponseMessage response = await client.PostAsync(requestUri, httpContent))
            {
                response.EnsureSuccessStatusCode();
                string responseBody = await response.Content.ReadAsStringAsync();
                return JObject.Parse(responseBody);
            }
        }

This is on mysql workbench -- give the image file path:

INSERT INTO XX_SAMPLE(id,image) VALUES(3,'/home/ganesan-pc/Documents/aios_database/confe.jpg');

in your setChilds, you might want to try looping thru the list and doing something like

child.parent = this;

you also should set up the cascade on the parent to the appropriate values.

this is a rehash of teoman shipahi's answer with a slightly less ambiguous name, and following the design priciple of defining code before you attempt to call it. (Whilst node allows you to do otherwise, it's not good a practice to put the cart before the horse.)

function rename_or_copy_and_delete (oldPath, newPath, callback) {

    function copy_and_delete () {
        var readStream = fs.createReadStream(oldPath);
        var writeStream = fs.createWriteStream(newPath);

        readStream.on('error', callback);
        writeStream.on('error', callback);
        readStream.on('close', 
              function () {
                fs.unlink(oldPath, callback);
              }
        );

        readStream.pipe(writeStream);
    }

    fs.rename(oldPath, newPath, 
        function (err) {
          if (err) {
              if (err.code === 'EXDEV') {
                  copy_and_delete();
              } else {
                  callback(err);
              }
              return;// << both cases (err/copy_and_delete)
          }
          callback();
        }
    );
}

To create a new helper you can follow the instructions from The Pixel Developer, but my advice is not to create a helper just for the logic required by a particular part of a particular application. Instead, use that logic in the controller to set the arrays to their final intended values. Once you got that, you pass them to the view using the Template Parser Class and (hopefully) you can keep the view clean from anything that looks like PHP using simple variables or variable tag pairs instead of echos and foreachs. i.e:

{blog_entries}
<h5>{title}</h5>
<p>{body}</p>
{/blog_entries}

instead of

<?php foreach ($blog_entries as $blog_entry): ?>
<h5><?php echo $blog_entry['title']; ?></h5>
<p><?php echo $blog_entry['body']; ?></p>
<?php endforeach; ?>

Another benefit from this approach is that you don't have to worry about adding the CI instance as you would if you use custom helpers to do all the work.

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

If it had been in PostgreSQL, use double quotes around the name, like:

select "from" from "table";

Note: Internally PostgreSQL automatically converts all unquoted commands and parameters to lower case. That have the effect that commands and identifiers aren't case sensitive. sEleCt * from tAblE; is interpreted as select * from table;. However, parameters inside double quotes are used as is, and therefore ARE case sensitive: select * from "table"; and select * from "Table"; gets the result from two different tables.

public class Application {

    private static List<HttpMessageConverter<?>> getMessageConverters() {
        List<HttpMessageConverter<?>> converters = new ArrayList<HttpMessageConverter<?>>();
        converters.add(new MappingJacksonHttpMessageConverter());
        return converters;
    }   

    public static void main(String[] args) {
        RestTemplate restTemplate = new RestTemplate();

        restTemplate.setMessageConverters(getMessageConverters());
        HttpHeaders headers = new HttpHeaders();
        headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
        HttpEntity<String> entity = new HttpEntity<String>(headers);
        //Page page = restTemplate.getForObject("http://graph.facebook.com/pivotalsoftware", Page.class);

        ResponseEntity<Page> response = 
                  restTemplate.exchange("http://graph.facebook.com/skbh86", HttpMethod.GET, entity, Page.class, "1");
        Page page = response.getBody();
        System.out.println("Name:    " + page.getId());
        System.out.println("About:   " + page.getFirst_name());
        System.out.println("Phone:   " + page.getLast_name());
        System.out.println("Website: " + page.getMiddle_name());
        System.out.println("Website: " + page.getName());
    }
}

You see the behavior when your target element contains child elements:

http://jsfiddle.net/ZCWvJ/7/

Each time your mouse enters or leaves a child element, mouseover is triggered, but not mouseenter.

$('#my_div').bind("mouseover mouseenter", function(e) {_x000D_
  var el = $("#" + e.type);_x000D_
  var n = +el.text();_x000D_
  el.text(++n);_x000D_
});

#my_div {_x000D_
  padding: 0 20px 20px 0;_x000D_
  background-color: #eee;_x000D_
  margin-bottom: 10px;_x000D_
  width: 90px;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
#my_div>div {_x000D_

I'm using 2.5, 2.6, and 3.0 from the shell with one line batch scripts of the form:

:: The @ symbol at the start turns off the prompt from displaying the command.
:: The % represents an argument, while the * means all of them.
@c:\programs\pythonX.Y\python.exe %*

Name them pythonX.Y.bat and put them somewhere in your PATH. Copy the file for the preferred minor version (i.e. the latest) to pythonX.bat. (E.g. copy python2.6.bat python2.bat.) Then you can use python2 file.py from anywhere.

However, this doesn't help or even affect the Windows file association situation. For that you'll need a launcher program that reads the #! line, and then associate that with .py and .pyw files.

We came across many situation where we need to check error and error logs to figure out issue we are facing we can check by possibly following method:

1.) On blank screen Some time we got nothing but blank screen instead of our site or message written The website encountered an unexpected error. Please try again later , so we can Print Errors to the Screen by adding

error_reporting(E_ALL);

ini_set('display_errors', TRUE); 

ini_set('display_startup_errors', TRUE); 

in index.php at top.;

2.) We should enable optional core module for Database Logging at /admin/build/modules, and then we can check logs your_domain_name/admin/reports/dblog

3.) We can use drush command also to check logs drush watchdog-show it will show recent ten message

or if we want to continue showing logs with more information we can user
drush watchdog-show --tail --full.

4.) Also we can enable core Syslog module this module logs events of operating system of any web server.

Use:

s.erase(std::remove_if(s.begin(), s.end(), my_predicate), s.end());

bool my_predicate(char c)
{
 return !(isalpha(c) || c=='_' || c==' '); // depending on you definition of special characters
}

And you'll get a clean string s.

erase() will strip it of all the special characters and is highly customisable with the my_predicate() function.

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

Assign the second variable for the $.each function() as well, makes it lot easier as it'll provide you the data (so you won't have to work with the indicies).

$.each(json, function(arrayID,group) {
            console.log('<a href="'+group.GROUP_ID+'">');
    $.each(group.EVENTS, function(eventID,eventData) {
            console.log('<p>'+eventData.SHORT_DESC+'</p>');
     });
});

Should print out everything you were trying in your question.

http://jsfiddle.net/niklasvh/hZsQS/

edit renamed the variables to make it bit easier to understand what is what.

To check Clustered Index exist on particular table or not:

SELECT * FROM SYS.indexes 
WHERE index_id = 1 AND name IN (SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE TABLE_NAME = 'Table_Name')

I guess you have installed the 2.7 version manually, while 2.6 comes from a package?

The simple answer is: uninstall python package.

The more complex one is: do not install manually in /usr/local. Build a package with 2.7 version and then upgrade.

Package handling depends on what distribution you use.

Another reason why you might get errors like "relation already exists" is if the DROP command did not execute correctly.

One reason this can happen is if there are other sessions connected to the database which you need to close first.

Do the build job on Jenkins first without Sonar configured. Then add Sonar, and run a build job again. Should fix the problem

It's often clearer to separate the two actions git pull does. The first thing it does is update the local tracking branc that corresponds to the remote branch. This can be done with git fetch. The second is that it then merges in changes, which can of course be done with git merge, though other options such as git rebase are occasionally useful.

I was porting one application from Visual C to gcc over Linux and I had the same problem with

malloc.c:3096: sYSMALLOc: Assertion using gcc on UBUNTU 11.

I moved the same code to a Suse distribution (on other computer ) and I don't have any problem.

I suspect that the problems are not in our programs but in the own libc.

For anyone that's coming to this and none of the other solutions helped, in my case this manifested on a route that handled image uploading but didn't handle timeouts, and thus if the upload took too long and timed out, when the callback was fired after the timeout response had been sent, calling res.send() resulted in the crash as the headers were already set to account for the timeout.

This was easily reproduced by setting a very short timeout and hitting the route with a decently-large image, the crash was reproduced every time.

What you need is overflow-y: scroll;

Demo

    textarea {_x000D_
        overflow-y: scroll;_x000D_
        height: 100px;_x000D_
        resize: none; /* Remove this if you want the user to resize the textarea */_x000D_
    }

<textarea></textarea>

Here I am giving you a proper example of one callback method . so suppose we have a method like method login() :

 public void login() {
    loginService = new LoginService();
    loginService.login(loginProvider, new LoginListener() {
        @Override
        public void onLoginSuccess() {
            loginService.getresult(true);
        }

        @Override
        public void onLoginFaliure() {
            loginService.getresult(false);

        }
    });
    System.out.print("@@##### get called");
}

I also put all the helper class here to make the example more clear: loginService class

public class LoginService implements Login.getresult{
public void login(LoginProvider loginProvider,LoginListener callback){

    String username  = loginProvider.getUsername();
    String pwd  = loginProvider.getPassword();
    if(username != null && pwd != null){
        callback.onLoginSuccess();
    }else{
        callback.onLoginFaliure();
    }

}

@Override
public void getresult(boolean value) {
    System.out.print("login success"+value);
}}

and we have listener LoginListener as :

interface LoginListener {
void onLoginSuccess();

void onLoginFaliure();

}

now I just wanted to test the method login() of class Login

 @Test
public void loginTest() throws Exception {
    LoginService service = mock(LoginService.class);
    LoginProvider provider = mock(LoginProvider.class);
    whenNew(LoginProvider.class).withNoArguments().thenReturn(provider);
    whenNew(LoginService.class).withNoArguments().thenReturn(service);
    when(provider.getPassword()).thenReturn("pwd");
    when(provider.getUsername()).thenReturn("username");
    login.getLoginDetail("username","password");

    verify(provider).setPassword("password");
    verify(provider).setUsername("username");

    verify(service).login(eq(provider),captor.capture());

    LoginListener listener = captor.getValue();

    listener.onLoginSuccess();

    verify(service).getresult(true);

also dont forget to add annotation above the test class as

@RunWith(PowerMockRunner.class)
@PrepareForTest(Login.class)

Here is an Alternative that worked for me:

yourFrame.setIconImage(Toolkit.getDefaultToolkit().getImage(getClass().getResource(Filepath)));

It's very similar to the accepted Answer.

Alright so after trying every solution out there to solve this exact issues on a wordpress blog, I might have done something either really stupid or genius... With no idea why there's an increase in Mysql connections, I used the php script below in my header to kill all sleeping processes..

So every visitor to my site helps in killing the sleeping processes..

<?php
$result = mysql_query("SHOW processlist");
while ($myrow = mysql_fetch_assoc($result)) {
if ($myrow['Command'] == "Sleep") {
mysql_query("KILL {$myrow['Id']}");}
}

I have written a C++ class which can be used to set the foreground and background color of output. This sample program serves as an example of printing This ->word<- is red. and formatting it so that the foreground color of word is red.

#include "colormod.h" // namespace Color
#include <iostream>
using namespace std;
int main() {
    Color::Modifier red(Color::FG_RED);
    Color::Modifier def(Color::FG_DEFAULT);
    cout << "This ->" << red << "word" << def << "<- is red." << endl;
}

Source

#include <ostream>
namespace Color {
    enum Code {
        FG_RED      = 31,
        FG_GREEN    = 32,
        FG_BLUE     = 34,
        FG_DEFAULT  = 39,
        BG_RED      = 41,
        BG_GREEN    = 42,
        BG_BLUE     = 44,
        BG_DEFAULT  = 49
    };
    class Modifier {
        Code code;
    public:
        Modifier(Code pCode) : code(pCode) {}
        friend std::ostream&
        operator<<(std::ostream& os, const Modifier& mod) {
            return os << "\033[" << mod.code << "m";
        }
    };
}

Advanced

You may want to add additional features to the class. It is, for example, possible to add the color magenta and even styles like boldface. To do this, just an another entry to the Code enumeration. This is a good reference.

If a parameter is passed as Any to your function, you can test on a special type like so :

   func isADate ( aValue : Any?) -> Bool{
        if (aValue as? Date) != nil {
            print ("a Date")
            return true
        }
        else {
            print ("This is not a date ")
            return false
        }
    }

Use nanosleep(2). It uses structure timespec that is used to specify intervals of time with nanosecond precision.

struct timespec {
           time_t tv_sec;        /* seconds */
           long   tv_nsec;       /* nanoseconds */
       };

SELECT * 
FROM tbl 
WHERE myDate BETWEEN #date one# AND #date two#;

Take a look at ToolTipster

• easy to use
• flexible
• pretty lightweight, compared to some other tooltip plugins (39kB)
• looks better, without additional styling
• has a good set of predefined themes

Store the previous scroll location, then see if the new one is greater than or less than that.

Here's a way to avoid any global variables (fiddle available here):

(function () {
    var previousScroll = 0;

    $(window).scroll(function(){
       var currentScroll = $(this).scrollTop();
       if (currentScroll > previousScroll){
           alert('down');
       } else {
          alert('up');
       }
       previousScroll = currentScroll;
    });
}()); //run this anonymous function immediately

If you are using swift4 and Alamofire v4.0 then the accepted code would look like this :

            let parameters: Parameters = [ "username" : email.text!, "password" : password.text! ]
            let urlString = "https://api.harridev.com/api/v1/login"
            let url = URL.init(string: urlString)
            Alamofire.request(url!, method: .put, parameters: parameters, encoding: JSONEncoding.default, headers: nil).responseJSON { response in
                 switch response.result
                {
                case .success(let json):
                    let jsonData = json as! Any
                    print(jsonData)
                case .failure(let error):
                    self.errorFailer(error: error)
                }
            }

You can bind to all of the radio buttons at once by name:

$('input[name=someRadioGroup]:radio').change(...);

Working example here: http://jsfiddle.net/Ey4fa/

The JAVA Documentation says:

java [ options ] -jar file.jar [ argument ... ]

and

... Non-option arguments after the class name or JAR file name are passed to the main function...

Maybe you have to put the arguments in single quotes.

I had a similar issue with zsh and nvm on Linux, I fixed it by adding nvm initialization script in ~/.profile and restart login session like this

export NVM_DIR="$HOME/.nvm" 
 [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm 
 [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

From this forum post

persist() is well defined. It makes a transient instance persistent. However, it doesn't guarantee that the identifier value will be assigned to the persistent instance immediately, the assignment might happen at flush time. The spec doesn't say that, which is the problem I have with persist().

persist() also guarantees that it will not execute an INSERT statement if it is called outside of transaction boundaries. This is useful in long-running conversations with an extended Session/persistence context.

A method like persist() is required.

save() does not guarantee the same, it returns an identifier, and if an INSERT has to be executed to get the identifier (e.g. "identity" generator, not "sequence"), this INSERT happens immediately, no matter if you are inside or outside of a transaction. This is not good in a long-running conversation with an extended Session/persistence context.

Does anybody have any experience to share?

There are 2^122 possible values for a type-4 UUID. (The spec says that you lose 2 bits for the type, and a further 4 bits for a version number.)

Assuming that you were to generate 1 million random UUIDs a second, the chances of a duplicate occurring in your lifetime would be vanishingly small. And to detect the duplicate, you'd have to solve the problem of comparing 1 million new UUIDs per second against all of the UUIDs you have previously generated¹!

The chances that anyone has experienced (i.e. actually noticed) a duplicate in real life are even smaller than vanishingly small ... because of the practical difficulty of looking for collisions.

Now of course, you will typically be using a pseudo-random number generator, not a source of truly random numbers. But I think we can be confident that if you are using a creditable provider for your cryptographic strength random numbers, then it will be cryptographic strength, and the probability of repeats will be the same as for an ideal (non-biased) random number generator.

However, if you were to use a JVM with a "broken" crypto- random number generator, all bets are off. (And that might include some of the workarounds for "shortage of entropy" problems on some systems. Or the possibility that someone has tinkered with your JRE, either on your system or upstream.)

^{1 - Assuming that you used "some kind of binary btree" as proposed by an anonymous commenter, each UUID is going to need O(NlogN) bits of RAM memory to represent N distinct UUIDs assuming low density and random distribution of the bits. Now multiply that by 1,000,000 and the number of seconds that you are going to run the experiment for. I don't think that is practical for the length of time needed to test for collisions of a high quality RNG. Not even with (hypothetical) clever representations.}

The keyword simply pops a frame from the call stack returning the control to the line following the function call.

Since every example here is just using walk (with join), i'd like to show a nice example and comparison with listdir:

import os, time

def listFiles1(root): # listdir
    allFiles = []; walk = [root]
    while walk:
        folder = walk.pop(0)+"/"; items = os.listdir(folder) # items = folders + files
        for i in items: i=folder+i; (walk if os.path.isdir(i) else allFiles).append(i)
    return allFiles

def listFiles2(root): # listdir/join (takes ~1.4x as long) (and uses '\\' instead)
    allFiles = []; walk = [root]
    while walk:
        folder = walk.pop(0); items = os.listdir(folder) # items = folders + files
        for i in items: i=os.path.join(folder,i); (walk if os.path.isdir(i) else allFiles).append(i)
    return allFiles

def listFiles3(root): # walk (takes ~1.5x as long)
    allFiles = []
    for folder, folders, files in os.walk(root):
        for file in files: allFiles+=[folder.replace("\\","/")+"/"+file] # folder+"\\"+file still ~1.5x
    return allFiles

def listFiles4(root): # walk/join (takes ~1.6x as long) (and uses '\\' instead)
    allFiles = []
    for folder, folders, files in os.walk(root):
        for file in files: allFiles+=[os.path.join(folder,file)]
    return allFiles


for i in range(100): files = listFiles1("src") # warm up

start = time.time()
for i in range(100): files = listFiles1("src") # listdir
print("Time taken: %.2fs"%(time.time()-start)) # 0.28s

start = time.time()
for i in range(100): files = listFiles2("src") # listdir and join
print("Time taken: %.2fs"%(time.time()-start)) # 0.38s

start = time.time()
for i in range(100): files = listFiles3("src") # walk
print("Time taken: %.2fs"%(time.time()-start)) # 0.42s

start = time.time()
for i in range(100): files = listFiles4("src") # walk and join
print("Time taken: %.2fs"%(time.time()-start)) # 0.47s

So as you can see for yourself, the listdir version is much more efficient. (and that join is slow)

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

This seems to do what you want (I found it on http://huddledmasses.org/powershell-find-path/):

Function Find-Path($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
## You could comment out the function stuff and use it as a script instead, with this line:
#param($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
   if($(Test-Path $Path -Type $type)) {
      return $path
   } else {
      [string[]]$paths = @($pwd);
      $paths += "$pwd;$env:path".split(";")

      $paths = Join-Path $paths $(Split-Path $Path -leaf) | ? { Test-Path $_ -Type $type }
      if($paths.Length -gt 0) {
         if($All) {
            return $paths;
         } else {
            return $paths[0]
         }
      }
   }
   throw "Couldn't find a matching path of type $type"
}
Set-Alias find Find-Path

You can use <LinearLayout> to group elements horizontaly. Also you should use style to set margins, background and other properties. This will allow you not to repeat code for every label you use. Here is an example:

<LinearLayout
                    style="@style/FormItem"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="horizontal">
                <TextView
                        style="@style/FormLabel"
                        android:layout_width="wrap_content"
                        android:layout_height="@dimen/default_element_height"
                        android:text="@string/name_label"
                        />

                <EditText
                        style="@style/FormText.Editable"
                        android:id="@+id/cardholderName"
                        android:layout_width="wrap_content"
                        android:layout_height="@dimen/default_element_height"
                        android:layout_weight="1"
                        android:gravity="right|center_vertical"
                        android:hint="@string/card_name_hint"
                        android:imeOptions="actionNext"
                        android:singleLine="true"
                        />
            </LinearLayout>

Also you can create a custom view base on the layout above. Have you looked at Creating custom view ?

No, it probably is actually working. It's just not readily visible. Instead of just using the header call, try doing that, then including 404.php, and then calling die.

You can test the fact that the HTTP/1.0 404 Not Found works by creating a PHP file named, say, test.php with this content:

<?php

header("HTTP/1.0 404 Not Found");
echo "PHP continues.\n";
die();
echo "Not after a die, however.\n";

Then viewing the result with curl -D /dev/stdout reveals:

HTTP/1.0 404 Not Found
Date: Mon, 04 Apr 2011 03:39:06 GMT
Server: Apache
X-Powered-By: PHP/5.3.2
Content-Length: 14
Connection: close
Content-Type: text/html

PHP continues.

for (var key in data) {
    alert("User " + data[key] + " is #" + key); // "User john is #234"
}

CASE 1 : SQLite 3.25.0+

Only the Version 3.25.0 of SQLite supports renaming columns. If your device is meeting this requirement, things are quite simple. The below query would solve your problem:

ALTER TABLE "MyTable" RENAME COLUMN "OldColumn" TO "NewColumn";

CASE 2 : SQLite Older Versions

You have to follow a different Approach to get the result which might be a little tricky

For example, if you have a table like this:

CREATE TABLE student(Name TEXT, Department TEXT, Location TEXT)

And if you wish to change the name of the column Location

Step 1: Rename the original table:

ALTER TABLE student RENAME TO student_temp;

Step 2: Now create a new table student with correct column name:

CREATE TABLE student(Name TEXT, Department TEXT, Address TEXT)

Step 3: Copy the data from the original table to the new table:

INSERT INTO student(Name, Department, Address) SELECT Name, Department, Location FROM student_temp;

Note: The above command should be all one line.

Step 4: Drop the original table:

DROP TABLE student_temp;

With these four steps you can manually change any SQLite table. Keep in mind that you will also need to recreate any indexes, viewers or triggers on the new table as well.

Yes, constructors can throw exceptions. Usually this means that the new object is immediately eligible for garbage collection (although it may not be collected for some time, of course). It's possible for the "half-constructed" object to stick around though, if it's made itself visible earlier in the constructor (e.g. by assigning a static field, or adding itself to a collection).

One thing to be careful of about throwing exceptions in the constructor: because the caller (usually) will have no way of using the new object, the constructor ought to be careful to avoid acquiring unmanaged resources (file handles etc) and then throwing an exception without releasing them. For example, if the constructor tries to open a FileInputStream and a FileOutputStream, and the first succeeds but the second fails, you should try to close the first stream. This becomes harder if it's a subclass constructor which throws the exception, of course... it all becomes a bit tricky. It's not a problem very often, but it's worth considering.

I had the same issue and solved it by closing the response at the end of the method:

try {
    // make the request and get the entity 
} catch(final Exception e) {
    // handle the exception
} finally {
    if(response != null) {
        response.close();
    }
}

You can access the delegate like this:

MainClass *appDelegate = (MainClass *)[[UIApplication sharedApplication] delegate];

Replace MainClass with the name of your application class.

Then, provided you have a property for the other view controller, you can call something like:

[appDelegate.viewController someMethod];

/* Function to remove white spaces on both sides of a string i.e trim */

void trim (char *s)
{
    int i;

    while (isspace (*s)) s++;   // skip left side white spaces
    for (i = strlen (s) - 1; (isspace (s[i])); i--) ;   // skip right side white spaces
    s[i + 1] = '\0';
    printf ("%s\n", s);
}

test is a non-destructive and, it doesn't return the result of the operation but it sets the flags register accordingly. To know what it really tests for you need to check the following instruction(s). Often out is used to check a register against 0, possibly coupled with a jz conditional jump.

Couldn't you just add it as an environment variable in Jenkins settings:

Manage Jenkins -> Global properties > Environment variables: And then click "Add" to add a property PATH and its value to what you need.

Try updating the line to:

ocr.Init(@"C:\", "eng", false); // the path here should be the parent folder of tessdata

#include <typeinfo>

...
string s = typeid(YourClass).name()

There are two ways to do it: creating filter condition 1) Manually 2) Dynamically.

Sample DataFrame:

val df = spark.createDataFrame(Seq(
  (0, "a1", "b1", "c1", "d1"),
  (1, "a2", "b2", "c2", "d2"),
  (2, "a3", "b3", null, "d3"),
  (3, "a4", null, "c4", "d4"),
  (4, null, "b5", "c5", "d5")
)).toDF("id", "col1", "col2", "col3", "col4")

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
|  2|  a3|  b3|null|  d3|
|  3|  a4|null|  c4|  d4|
|  4|null|  b5|  c5|  d5|
+---+----+----+----+----+

1) Creating filter condition manually i.e. using DataFrame where or filter function

df.filter(col("col1").isNotNull && col("col2").isNotNull).show

or

df.where("col1 is not null and col2 is not null").show

Result:

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
|  2|  a3|  b3|null|  d3|
+---+----+----+----+----+

2) Creating filter condition dynamically: This is useful when we don't want any column to have null value and there are large number of columns, which is mostly the case.

To create the filter condition manually in these cases will waste a lot of time. In below code we are including all columns dynamically using map and reduce function on DataFrame columns:

val filterCond = df.columns.map(x=>col(x).isNotNull).reduce(_ && _)

How filterCond looks:

filterCond: org.apache.spark.sql.Column = (((((id IS NOT NULL) AND (col1 IS NOT NULL)) AND (col2 IS NOT NULL)) AND (col3 IS NOT NULL)) AND (col4 IS NOT NULL))

Filtering:

val filteredDf = df.filter(filterCond)

Result:

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
+---+----+----+----+----+

As described here, you need to edit (as root) the file /etc/apt/sources.list (the easiest way to do this is to type sudo gedit /etc/apt/sources.list). On the line that mentions http://packages.ros.org/ros/ubuntu you need to add [trusted=yes] after the word deb (you might need to add it as a separate word). Then save the file and try again.

Since at the time of installing of any module it mainly put corresponding .pm files in respective directories. So if you want to remove module only for some testing purpose or temporarily best is to find the path where module is stored using perldoc -l <MODULE> and then simply move the module from there to some other location. This approach can also be tried as a more permanent solution but i am not aware of any negative consequences as i do it mainly for testing.

This Works fine for me

var osvar = process.platform;

if (osvar == 'darwin') {
    console.log("you are on a mac os");
}else if(osvar == 'win32'){
    console.log("you are on a windows os")
}else{
    console.log("unknown os")
}

I Changed Sid Value to orcl, it works fine and connection established

If you want to do some high-powered debugging, you can subscribe to every change of the state and pause the app to see what's going on in detail as follows.

store.subscribe( () => {
  console.log('state\n', store.getState());
  debugger;
});

Place that in the file where you do createStore.

To copy the state object from the console to the clipboard, follow these steps:

1. Right-click an object in Chrome's console and select Store as Global Variable from the context menu. It will return something like temp1 as the variable name.

2. Chrome also has a copy() method, so copy(temp1) in the console should copy that object to your clipboard.

You can view the object in a json viewer like this one: http://jsonviewer.stack.hu/

You can compare two json objects here: http://www.jsondiff.com/

For this problem, I have finally put a new <i> tag to refresh the select instead. Don't try to trigger an event if the selected option is the same that the one already selected.

If user click on the "refresh" button, I trigger the onchange event of my select with :

const refreshEquipeEl = document.getElementById("refreshEquipe1");

function onClickRefreshEquipe(event){
    let event2 = new Event('change');
    equipesSelectEl.dispatchEvent(event2);
}
refreshEquipeEl.onclick = onClickRefreshEquipe;

This way, I don't need to try select the same option in my select.

You can also use npmlog by issacs, recommended in https://npmjs.org/doc/coding-style.html.

You can find this module here https://github.com/isaacs/npmlog

Console.WriteLine(decimal.Round(pay,2));

In Swift:

var uuid: String = NSUUID().UUIDString
println("uuid: \(uuid)")

SELECT DISTINCT Category FROM MonitoringJob ORDER BY Category ASC

Place AddDefaultCharset UTF-8 into /etc/apache2/conf.d/charset. In fact, it's already there. You just have to uncomment it by removing the preceding #.

Your data.frame mat is rectangular (n_rows!= n_cols).

Therefore, you cannot make a data.frame out of the column- and rownames, because each column in a data.frame must be the same length.

Maybe this suffices your needs:

require(reshape2)
mat$id <- rownames(mat) 
melt(mat)

Some benefits of using getters and setters (known as encapsulation or data-hiding):

(originally answered here)

1. The fields of a class can be made read-only (by only providing the getter) or write-only (by only providing the setter). This gives the class a total control of who gets to access/modify its fields.

Example:

class EncapsulationExample {
    private int readOnly = -1;  // this value can only be read, not altered
    private int writeOnly = 0;    // this value can only be changed, not viewed
    public int getReadOnly() {
        return readOnly;
    }
    public int setWriteOnly(int w) {
        writeOnly = w;
    }
}

2. The users of a class do not need to know how the class actually stores the data. This means data is separated and exists independently from the users thus allowing the code to be more easily modified and maintained. This allows the maintainers to make frequent changes like bug fixes, design and performance enhancements, all while not impacting users.

Furthermore, encapsulated resources are uniformly accessible to each user and have identical behavior independent of the user since this behavior is internally defined in the class.

Example (getting a value):

class EncapsulationExample {
    private int value;
    public int getValue() {     
        return value; // return the value
    }
}

Now what if I wanted to return twice the value instead? I can just alter my getter and all the code that is using my example doesn't need to change and will get twice the value:

class EncapsulationExample {
    private int value;
    public int getValue() {
        return value*2; // return twice the value
    }
}

3. Makes the code cleaner, more readable and easier to comprehend.

Here is an example:

No encapsulation:

class Box {
    int widthS; // width of the side
    int widthT; // width of the top
    // other stuff
}

// ...
Box b = new Box();
int w1 = b.widthS;  // Hm... what is widthS again? 
int w2 = b.widthT;  // Don't mistake the names. I should make sure I use the proper variable here!

With encapsulation:

class Box {
    private int widthS; // width of the side
    private int widthT; // width of the top
    public int getSideWidth() {
        return widthS;
    }
    public int getTopWIdth() {
        return widthT;
    }
    // other stuff
}

// ...
Box b = new Box();
int w1 = b.getSideWidth(); // Ok, this one gives me the width of the side
int w2 = b.getTopWidth(); // and this one gives me the width of the top. No confusion, whew!

Look how much more control you have on which information you are getting and how much clearer this is in the second example. Mind you, this example is trivial and in real-life the classes you would be dealing with a lot of resources being accessed by many different components. Thus, encapsulating the resources makes it clearer which ones we are accessing and in what way (getting or setting).

Here is good SO thread on this topic.

Here is good read on data encapsulation.

Yes, the constant CI_VERSION will give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.php As of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php

For example,

echo CI_VERSION; // echoes something like 1.7.1

In the HTML page you have to to put your css code between the tags, while in the body a div which has as id rectangle. Here the code:

<!doctype>
<html>
<head>
<style>
#rectangle 
{
   all your css code
}
</style>
</head>
<body>
<div id="rectangle"></div>
</body>
</html>

I use abline() with extremely wide vertical lines to fill the plot space:

abline(v = xpoints, col = "grey90", lwd = 80)

You have to create the frame, then the ablines, and then plot the points so they are visible on top. You can even use a second abline() statement to put thin white or black lines over the grey, if desired.

Example:

xpoints = 1:20
y = rnorm(20)
plot(NULL,ylim=c(-3,3),xlim=xpoints)
abline(v=xpoints,col="gray90",lwd=80)
abline(v=xpoints,col="white")
abline(h = 0, lty = 2) 
points(xpoints, y, pch = 16, cex = 1.2, col = "red")

Presumably you could kick off a setTimeout call in mousedown, and then cancel it in mouseup (if mouseup happens before your timeout completes).

However, looks like there is a plugin: longclick.

Use the isSelected method.

You can also use an ItemListener so you'll be notified when it's checked or unchecked.

To check for the NULL data for column1 and consider your datatype of it is String, you could use below command :

select * from tbl_name where column1 is null or column1 <> '';

In some cases, it's possible to automatically parallelize loops using Numba, though it only works with a small subset of Python:

from numba import njit, prange

@njit(parallel=True)
def prange_test(A):
    s = 0
    # Without "parallel=True" in the jit-decorator
    # the prange statement is equivalent to range
    for i in prange(A.shape[0]):
        s += A[i]
    return s

Unfortunately, it seems that Numba only works with Numpy arrays, but not with other Python objects. In theory, it might also be possible to compile Python to C++ and then automatically parallelize it using the Intel C++ compiler, though I haven't tried this yet.

The techniques "eval()" and "JSON.parse()" use mutually exclusive formats.

• With "eval()" parenthesis are required.
• With "JSON.parse()" parenthesis are forbidden.

Beware, there are "stringify()" functions that produce "eval" format. For ajax, you should use only the JSON format.

While "eval" incorporates the entire JavaScript language, JSON uses only a tiny subset of the language. Among the constructs in the JavaScript language that "eval" must recognize is the "Block statement" (a.k.a. "compound statement"); which is a pair or curly braces "{}" with some statements inside. But curly braces are also used in the syntax of object literals. The interpretation is differentiated by the context in which the code appears. Something might look like an object literal to you, but "eval" will see it as a compound statement.

In the JavaScript language, object literals occur to the right of an assignment.

var myObj = { ...some..code..here... };

Object literals don't occur on their own.

{ ...some..code..here... }   // this looks like a compound statement

Going back to the OP's original question, asked in 2008, he inquired why the following fails in "eval()":

{ title: "One", key: "1" }

The answer is that it looks like a compound statement. To convert it into an object, you must put it into a context where a compound statement is impossible. That is done by putting parenthesis around it

( { title: "One", key: "1" } )    // not a compound statment, so must be object literal

The OP also asked why a similar statement did successfully eval:

[ { title: "One", key: "1" }, { title: "Two", key: "2" } ]

The same answer applies -- the curly braces are in a context where a compound statement is impossible. This is an array context, "[...]", and arrays can contain objects, but they cannot contain statements.

Unlike "eval()", JSON is very limited in its capabilities. The limitation is intentional. The designer of JSON intended a minimalist subset of JavaScript, using only syntax that could appear on the right hand side of an assignment. So if you have some code that correctly parses in JSON...

var myVar = JSON.parse("...some...code...here...");

...that implies it will also legally parse on the right hand side of an assignment, like this..

var myVar = ...some..code..here... ;

But that is not the only restriction on JSON. The BNF language specification for JSON is very simple. For example, it does not allow for the use of single quotes to indicate strings (like JavaScript and Perl do) and it does not have a way to express a single character as a byte (like 'C' does). Unfortunately, it also does not allow comments (which would be really nice when creating configuration files). The upside of all those limitations is that parsing JSON is fast and offers no opportunity for code injection (a security threat).

Because of these limitations, JSON has no use for parenthesis. Consequently, a parenthesis in a JSON string is an illegal character.

Always use JSON format with ajax, for the following reasons:

• A typical ajax pipeline will be configured for JSON.
• The use of "eval()" will be criticised as a security risk.

As an example of an ajax pipeline, consider a program that involves a Node server and a jQuery client. The client program uses a jQuery call having the form $.ajax({dataType:'json',...etc.});. JQuery creates a jqXHR object for later use, then packages and sends the associated request. The server accepts the request, processes it, and then is ready to respond. The server program will call the method res.json(data) to package and send the response. Back at the client side, jQuery accepts the response, consults the associated jqXHR object, and processes the JSON formatted data. This all works without any need for manual data conversion. The response involves no explicit call to JSON.stringify() on the Node server, and no explicit call to JSON.parse() on the client; that's all handled for you.

The use of "eval" is associated with code injection security risks. You might think there is no way that can happen, but hackers can get quite creative. Also, "eval" is problematic for Javascript optimization.

If you do find yourself using a using a "stringify()" function, be aware that some functions with that name will create strings that are compatible with "eval" and not with JSON. For example, in Node, the following gives you function that creates strings in "eval" compatible format:

var stringify = require('node-stringify'); // generates eval() format

This can be useful, but unless you have a specific need, it's probably not what you want.

import datetime
def today_date():
    '''
    utils:
    get the datetime of today
    '''
    date=datetime.datetime.now().date()
    date=pd.to_datetime(date)
    return date
Df['Date'] = today_date()

this could be safely used in pandas dataframes.

All markers in Google Android Maps Api v2 are clickable. You don't need to set any additional properties to your marker. What you need to do - is to register marker click callback to your googleMap and handle click within callback:

public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity
    implements OnMarkerClickListener
{
    private Marker myMarker;    

    private void setUpMap()
    {
        .......
        googleMap.setOnMarkerClickListener(this);

        myMarker = googleMap.addMarker(new MarkerOptions()
                    .position(latLng)
                    .title("My Spot")
                    .snippet("This is my spot!")
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
        ......
    }

    @Override
    public boolean onMarkerClick(final Marker marker) {

        if (marker.equals(myMarker)) 
        {
            //handle click here
        }
    }
}

here is a good guide on google about marker customization

You have to create two triggers, but you can move the common code into a procedure and have them both call the procedure.

This structure I am using to check if my app has permission and than request if it does not have permission. So in my main code from where i want to check write following :

int MyVersion = Build.VERSION.SDK_INT;
if (MyVersion > Build.VERSION_CODES.LOLLIPOP_MR1) {
                if (!checkIfAlreadyhavePermission()) {
                    requestForSpecificPermission();
                }
}

Module checkIfAlreadyhavePermission() is implemented as :

private boolean checkIfAlreadyhavePermission() {
    int result = ContextCompat.checkSelfPermission(this, Manifest.permission.GET_ACCOUNTS);
    if (result == PackageManager.PERMISSION_GRANTED) {
        return true;
    } else {
        return false;
    }
}

Module requestForSpecificPermission() is implemented as :

private void requestForSpecificPermission() {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.GET_ACCOUNTS, Manifest.permission.RECEIVE_SMS, Manifest.permission.READ_SMS, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 101);
}

and Override in Activity :

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case 101:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //granted
            } else {
                //not granted
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

Sometimes, we need to create a new instance of an inner class that can't be static because it depends on some global variables of the parent class. In that situation, if you try to create the instance of an inner class that is not static, a not an enclosing class error is thrown.

Taking the example of the question, what if ZShape can't be static because it need global variable of Shape class?

How can you create new instance of ZShape? This is how:

Add a getter in the parent class:

public ZShape getNewZShape() {
    return new ZShape();
}

Access it like this:

Shape ss = new Shape();
ZShape s = ss.getNewZShape();

I think your date format does not make sense. There is no 13:00 PM. Remove the "aaa" at the end of your format or turn the HH into hh.

Nevertheless, this works fine for me:

String testDate = "29-Apr-2010,13:00:14 PM";
DateFormat formatter = new SimpleDateFormat("d-MMM-yyyy,HH:mm:ss aaa");
Date date = formatter.parse(testDate);
System.out.println(date);

It prints "Thu Apr 29 13:00:14 CEST 2010".

The reason that does not work is because this has no specific meaning inside of an if statement, you will have to go back to a level of scope where this is defined (a function).

For example:

$('#element1').click(function() {
    console.log($(this).attr('id')); // logs "element1"

    if ($('#element2').hasClass('class')) {
        console.log($(this).attr('id')); // still logs "element1"
    }
});

you could use a recursive method like below:

public static String getAllNumbersFromString(String input) {
        if (input == null || input.length() == 0) {
            return "";
        }
        char c = input.charAt(input.length() - 1);
        String newinput = input.substring(0, input.length() - 1);

            if (c >= '0' && c<= '9') {
            return getAllNumbersFromString(newinput) + c;

        } else {
            return getAllNumbersFromString(newinput);
        }

To find the AWS_SECRET_ACCESS_KEY Its better to create new create "IAM" user Here is the steps https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_create.html 1. Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com/iam/.

2. In the navigation pane, choose Users and then choose Add user.

You could do something this way:

$(document.body).find('*').each(function() {
    if($(this).hasClass('lollypops')){ //class replacing..many ways to do this :)
        $(this).removeClass('lollypops');
        $(this).addClass('marshmellows');
    }
    var tmp = $(this).children().remove(); //removing and saving children to a tmp obj
    var text = $(this).text(); //getting just current node text
    text = text.replace(/lollypops/g, "marshmellows"); //replacing every lollypops occurence with marshmellows
    $(this).text(text); //setting text
    $(this).append(tmp); //re-append 'foundlings'
});

I had a very similar requirement (importing a base64 encoded image from an external xml import file. After using xml2json-light library to convert to a json object, I was able to leverage insight from cuixiping's answer above to convert the incoming b64 encoded image to a file object.

const imgName = incomingImage['FileName'];
const imgExt = imgName.split('.').pop();
let mimeType = 'image/png';
if (imgExt.toLowerCase() !== 'png') {
    mimeType = 'image/jpeg';
}
const imgB64 = incomingImage['_@ttribute'];
const bstr = atob(imgB64);
let n = bstr.length;
const u8arr = new Uint8Array(n);
while (n--) {
  u8arr[n] = bstr.charCodeAt(n);
}
const file = new File([u8arr], imgName, {type: mimeType});

My incoming json object had two properties after conversion by xml2json-light: FileName and _@ttribute (which was b64 image data contained in the body of the incoming element.) I needed to generate the mime-type based on the incoming FileName extension. Once I had all the pieces extracted/referenced from the json object, it was a simple task (using cuixiping's supplied code reference) to generate the new File object which was completely compatible with my existing classes that expected a file object generated from the browser element.

Hope this helps connects the dots for others.

Notice that instance methods are also attributes (of the class) and that you could set them at the class or instance level if you really wanted to be a badass. Or that you may set a class variable (which is also an attribute of the class), where handy readonly properties won't work neatly out of the box. What I'm trying to say is that the "readonly attribute" problem is in fact more general than it's usually perceived to be. Fortunately there are conventional expectations at work that are so strong as to blind us wrt these other cases (after all, almost everything is an attribute of some sort in python).

Building upon these expectations I think the most general and lightweight approach is to adopt the convention that "public" (no leading underscore) attributes are readonly except when explicitly documented as writeable. This subsumes the usual expectation that methods won't be patched and class variables indicating instance defaults are better let alone. If you feel really paranoid about some special attribute, use a readonly descriptor as a last resource measure.

I really like AVee's solution with the lowest IP connection metric! But if a second nic with the same metric is installed, the MAC comparison could fail...

Better you store the description of the interface with the MAC. In later comparisons you can identify the right nic by this string. Here is a sample code:

   public static string GetMacAndDescription()
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled=true");
        IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
        string mac = (from o in objects orderby o["IPConnectionMetric"] select o["MACAddress"].ToString()).FirstOrDefault();
        string description = (from o in objects orderby o["IPConnectionMetric"] select o["Description"].ToString()).FirstOrDefault();
        return mac + ";" + description;
    }

    public static string GetMacByDescription( string description)
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled=true");
        IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
        string mac = (from o in objects where o["Description"].ToString() == description select o["MACAddress"].ToString()).FirstOrDefault();
        return mac;
    }

I had this same problem and stumbled upon the following simple solution. Just add a bit of padding to the image and it resizes itself to fit within the div.

<div class="col-sm-3">
  <img src="xxx.png" class="img-responsive" style="padding-top: 5px">
</div>

Unfortunatelly, for IIS installed on Windows 7/8 machines, there is no option to create users only for IIS authentification. For Windows Server there is that option where you can add users from IIS Manager UI. These users have roles only on IIS, but not for the rest of the system. In this article it shows how you add users, but it is incorrect stating that is also appliable to standard OS, it only applies to server versions.

For those who didn't know what next, just add new module file and put @jor code (with my little hacked, supporting 'nothing' array) below.

Module ArrayExtension
    <Extension()> _
    Public Sub Add(Of T)(ByRef arr As T(), item As T)
        If arr IsNot Nothing Then
            Array.Resize(arr, arr.Length + 1)
            arr(arr.Length - 1) = item
        Else
            ReDim arr(0)
            arr(0) = item
        End If

    End Sub
End Module

Try adding 'autoReconnect=true' to the jdbc connection string

sudo dscl . -create /Users/joeadmin

sudo dscl . -append /Groups/admin GroupMembership joeadmin

press enter after every sentence

Then do a:

sudo reboot

Change joeadmin to whatever you want, but it has to be the same all the way through. You can also put a password of your choice after password.

Try this it works for me:

In jquery, u can delcare variable two styles.

One is,

$.name = 'anirudha';
alert($.name);
