I used inbuilt function dropDuplicates(). Scala code given below

val data = sc.parallelize(List(("Foo",41,"US",3),
("Foo",39,"UK",1),
("Bar",57,"CA",2),
("Bar",72,"CA",2),
("Baz",22,"US",6),
("Baz",36,"US",6))).toDF("x","y","z","count")

data.dropDuplicates(Array("x","count")).show()

Output :

+---+---+---+-----+
|  x|  y|  z|count|
+---+---+---+-----+
|Baz| 22| US|    6|
|Foo| 39| UK|    1|
|Foo| 41| US|    3|
|Bar| 57| CA|    2|
+---+---+---+-----+

Yes, it is possible to add metatags with Javascript. I did in my example

Android not respecting metatag removal?

But, I dont know how to change it other then removing it. Btw, in my example.. when you click the 'ADD' button it adds the tag and the viewport changes respectively but I dont know how to revert it back (remove it, in Android).. I wish there was firebug for Android so I saw what was happening. Firefox does remove the tag. if anybody has any ideas on this please note so in my question.

Try this JS solution that toggles webkitOverflowScrolling style. The trick here is that this style is off, mobile Safari goes to ordinary scrolling and prevents over-bounce — alas, it is not able to cancel ongoing drag. This complex solution also tracks onscroll as bounce over the top makes scrollTop negative that may be tracked. This solution was tested on iOS 12.1.1 and has single drawback: while accelerating the scroll single over-bounce still happens as resetting the style may not cancel it immediately.

function preventScrollVerticalBounceEffect(container) {
  setTouchScroll(true) //!: enable before the first scroll attempt

  container.addEventListener("touchstart", onTouchStart)
  container.addEventListener("touchmove", onTouch, { passive: false })
  container.addEventListener("touchend", onTouchEnd)
  container.addEventListener("scroll", onScroll)

  function isTouchScroll() {
    return !!container.style.webkitOverflowScrolling
  }

  let prevScrollTop = 0, prevTouchY, opid = 0

  function setTouchScroll(on) {
    container.style.webkitOverflowScrolling = on ? "touch" : null

    //Hint: auto-enabling after a small pause makes the start
    // smoothly accelerated as required. After the pause the
    // scroll position is settled, and there is no delta to
    // make over-bounce by dragging the finger. But still,
    // accelerated content makes short single over-bounce
    // as acceleration may not be off instantly.

    const xopid = ++opid
    !on && setTimeout(() => (xopid === opid) && setTouchScroll(true), 250)

    if(!on && container.scrollTop < 16)
      container.scrollTop = 0
    prevScrollTop = container.scrollTop
  }

  function isBounceOverTop() {
    const dY = container.scrollTop - prevScrollTop
    return dY < 0 && container.scrollTop < 16
  }

  function isBounceOverBottom(touchY) {
    const dY = touchY - prevTouchY

    //Hint: trying to bounce over the bottom, the finger moves
    // up the screen, thus Y becomes smaller. We prevent this.

    return dY < 0 && container.scrollHeight - 16 <=
      container.scrollTop + container.offsetHeight
  }

  function onTouchStart(e) {
    prevTouchY = e.touches[0].pageY
  }

  function onTouch(e) {
    const touchY = e.touches[0].pageY

    if(isBounceOverBottom(touchY)) {
      if(isTouchScroll())
        setTouchScroll(false)
      e.preventDefault()
    }

    prevTouchY = touchY
  }

  function onTouchEnd() {
    prevTouchY = undefined
  }

  function onScroll() {
    if(isTouchScroll() && isBounceOverTop()) {
      setTouchScroll(false)
    }
  }
}

Coming back to this a few years later, this problem is more than likely related to the Windows maximum path limit:

Naming Files, Paths, and Namespaces, Maximum Path Length Limitation

What you are looking for is a simple directive like:

location ~* \.(?:manifest|appcache|html?|xml|json)$ {
    expires -1;
}

The above will not cache the extensions within the (). You can configure different directives for different file types.

From the code you showed us, the only thing we can tell is that you are trying to create an array from a list that isn't shaped like a multi-dimensional array. For example

numpy.array([[1,2], [2, 3, 4]])

or

numpy.array([[1,2], [2, [3, 4]]])

will yield this error message, because the shape of the input list isn't a (generalised) "box" that can be turned into a multidimensional array. So probably UnFilteredDuringExSummaryOfMeansArray contains sequences of different lengths.

Edit: Another possible cause for this error message is trying to use a string as an element in an array of type float:

numpy.array([1.2, "abc"], dtype=float)

That is what you are trying according to your edit. If you really want to have a NumPy array containing both strings and floats, you could use the dtype object, which enables the array to hold arbitrary Python objects:

numpy.array([1.2, "abc"], dtype=object)

Without knowing what your code shall accomplish, I can't judge if this is what you want.

Laravel has a built-in method to shuffle the order of the results.

Here is a quote from the documentation:

shuffle()

The shuffle method randomly shuffles the items in the collection:

$collection = collect([1, 2, 3, 4, 5]);

$shuffled = $collection->shuffle();

$shuffled->all();

// [3, 2, 5, 1, 4] - (generated randomly)

You can see the documentation here.

You shouldn't overload the templates with complex logic, it's a bad practice. Remember to always keep it simple!

The better approach would be to extract this logic into reusable function on your $rootScope:

.run(function ($rootScope) {
  $rootScope.inArray = function (item, array) {
    return (-1 !== array.indexOf(item));
  };
})

Then, use it in your template:

<li ng-class="{approved: inArray(jobSet, selectedForApproval)}"></li>

I think everyone will agree that this example is much more readable and maintainable.

So after asking another question, someone helped me figure out that under File > Project Structure > Modules, there's supposed to be stuff there. If it's empty (says "Nothing to show"), do the following:

1. In File > Project Structure > Modules, click the "+" button,
2. Press Enter (because weirdly it won't let me click on "New Module")
3. In the window that pops up, click on the "..." next button which takes you to the Content root. Find your root folder and select it
4. Click the "ok" button
5. Ignore any warning that says the name is already in use

The best way for converting to Numpy Array is using '.to_numpy(self, dtype=None, copy=False)'. It is new in version 0.24.0.Refrence

You can also use '.array'.Refrence

Pandas .as_matrix deprecated since version 0.23.0.

if you are working on dynamic permissions and any permission like ACCESS_FINE_LOCATION,ACCESS_COARSE_LOCATION giving error "cannot resolve method PERMISSION_NAME" in this case write you code with permission name and then rebuild your project this will regenerate the manifest(Manifest.permission) file.

Simplest left to right swipe detector:

In your activity class add following attributes:

private float x1,x2;
static final int MIN_DISTANCE = 150;

and override onTouchEvent() method:

@Override
public boolean onTouchEvent(MotionEvent event)
{     
    switch(event.getAction())
    {
      case MotionEvent.ACTION_DOWN:
          x1 = event.getX();                          
      break;          
      case MotionEvent.ACTION_UP:
          x2 = event.getX();
          float deltaX = x2 - x1;
          if (Math.abs(deltaX) > MIN_DISTANCE)
          {
              Toast.makeText(this, "left2right swipe", Toast.LENGTH_SHORT).show ();
          }
          else
          {
              // consider as something else - a screen tap for example
          }                       
      break;    
    }            
    return super.onTouchEvent(event);        
}

For me it was tls12:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

In order to prevent 'Access Denied' error:

Start -> search 'Services' -> right click -> Run as admistrator

Try this (apply to a class you image is in (not img itself), e.g.

.myimage {
  background: transparent url("yourimage.png") no-repeat top center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: 100%;
  height: 500px;
}

I wanted something similar - a function that parses a string that can be passed as a parameter or piped.

I came up with a solution as below (works as #!/bin/sh and as #!/bin/bash)

#!/bin/sh

set -eu

my_func() {
    local content=""
    
    # if the first param is an empty string or is not set
    if [ -z ${1+x} ]; then
 
        # read content from a pipe if passed or from a user input if not passed
        while read line; do content="${content}$line"; done < /dev/stdin

    # first param was set (it may be an empty string)
    else
        content="$1"
    fi

    echo "Content: '$content'"; 
}


printf "0. $(my_func "")\n"
printf "1. $(my_func "one")\n"
printf "2. $(echo "two" | my_func)\n"
printf "3. $(my_func)\n"
printf "End\n"

Outputs:

0. Content: ''
1. Content: 'one'
2. Content: 'two'
typed text
3. Content: 'typed text'
End

For the last case (3.) you need to type, hit enter and CTRL+D to end the input.

For future reference, deleting nodes with SimpleXML can be a pain sometimes, especially if you don't know the exact structure of the document. That's why I have written SimpleDOM, a class that extends SimpleXMLElement to add a few convenience methods.

For instance, deleteNodes() will delete all nodes matching a XPath expression. And if you want to delete all nodes with the attribute "id" equal to "A5", all you have to do is:

// don't forget to include SimpleDOM.php
include 'SimpleDOM.php';

// use simpledom_load_string() instead of simplexml_load_string()
$data = simpledom_load_string(
    '<data>
        <seg id="A1"/>
        <seg id="A5"/>
        <seg id="A12"/>
        <seg id="A29"/>
        <seg id="A30"/>
    </data>'
);

// and there the magic happens
$data->deleteNodes('//seg[@id="A5"]');

You can use xpath for for identifying that element.

Use "\n" instead of '\n'

There are solutions here that do it in O(l1+l2) that don't count repeating items, and slow solutions (at least O(l1*l2), but probably more expensive) that do consider repeating items.

So I figured I should add an O(l1log(l1)+l2(log(l2)) solution. This is particularly useful if the lists are already sorted.

def common_elems_with_repeats(first_list, second_list):
    first_list = sorted(first_list)
    second_list = sorted(second_list)
    marker_first = 0
    marker_second = 0
    common = []
    while marker_first < len(first_list) and marker_second < len(second_list):
        if(first_list[marker_first] == second_list[marker_second]):
            common.append(first_list[marker_first])
            marker_first +=1
            marker_second +=1
        elif first_list[marker_first] > second_list[marker_second]:
            marker_second += 1
        else:
            marker_first += 1
    return common

Another faster solution would include making a item->count map from list1, and iterating through list2, while updating the map and counting dups. Wouldn't require sorting. Would require extra a bit extra memory but it's technically O(l1+l2).

After spending half a day with nothing working. Using a header check service though everything was working. The firewall at work was stripping them

This is the mathematical way:

For year, month (1 to 12):

int daysInMonth = month !== 2 ? 
  31 - (((month - 1) % 7) % 2) : 
  28 + (year % 4 == 0 ? 1 : 0) - (year % 100 == 0 ? 1 : 0) + (year % 400 == 0 ? 1 : 0)

Sorry for replying on an older question, but I would like to clarify the last question.

You use a "get" method for your form. When the name of your input-field is "g", it will make a URL like this:

https://www.google.com/search?g=[value from input-field]

But when you search with google, you notice the following URL:

https://www.google.nl/search?q=google+search+bar

Google uses the "q" Querystring variable as it's search-query. Therefor, renaming your field from "g" to "q" solved the problem.

Simply, type the command:

~$ whereis "program name"

It's ugly, but you can use the setfacl command to achieve exactly what you want.

On a Solaris machine, I have a file that contains the acls for users and groups. Unfortunately, you have to list all of the users (at least I couldn't find a way to make this work otherwise):

user::rwx
user:user_a:rwx
user:user_b:rwx
...
group::rwx
mask:rwx
other:r-x
default:user:user_a:rwx
default:user:user_b:rwx
....
default:group::rwx
default:user::rwx
default:mask:rwx
default:other:r-x

Name the file acl.lst and fill in your real user names instead of user_X.

You can now set those acls on your directory by issuing the following command:

setfacl -f acl.lst /your/dir/here

You can use either of the following:

include "class.twitter.php";

or

require "class.twitter.php";

Using require (or require_once if you want to ensure the class is only loaded once during execution) will cause a fatal error to be raised if the file doesn't exist, whereas include will only raise a warning. See http://php.net/require and http://php.net/include for more details

I realize this is a very old post, but I encountered a similar issue in which my displayed image always had a border around it. I was trying to fill the browser window with a single image. Adding styles like border:none; did not remove the border and neither did margin:0; or padding:0; or any combination of the three.

However, adding position:absolute;top:0;left:0; fixed the problem.

The original post above has position:absolute; but does not have top:0;left:0; and this was adding a default border on my page.

To illustrate the solution, this has a white border (to be precise, it has a top and left offset):

<img src="filename.jpg"
style="width:100%;height:100%;position:absolute;">

This does not have a border:

<img src="filename.jpg"
style="width:100%;height:100%;position:absolute;top:0;left:0;">

Hopefully this helps someone finding this post looking to resolve a similar problem.

Multiple ways to do this :

var str1:String="\(23)"
var str2:String=String(format:"%d",234)

You can create your own extension method to do this:

public static bool Contains(this string source, string toCheck, StringComparison comp)
  {
    return source != null && toCheck != null && source.IndexOf(toCheck, comp) >= 0;
  }

And then call:

 mystring.Contains(myStringToCheck, StringComparison.OrdinalIgnoreCase);

Alternatively, you can use Inner Queries to do so.

SQL> INSERT INTO <NEW_TABLE> SELECT * FROM CUSTOMERS WHERE ID IN (SELECT ID FROM <OLD_TABLE>);

Hope this helps!

import time  
current = time.time()

...job...
end = time.time()
diff = end - current

would that work for you?

There are several problems here:

1. The newdata argument of predict() needs a predictor variable. You should thus pass it values for Coupon, instead of Total, which is the response variable in your model.

2. The predictor variable needs to be passed in as a named column in a data frame, so that predict() knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).

3. For this to work, your original call should pass df in through the data argument, rather than using it directly in your formula. (This way, the name of the column in newdata will be able to match the name on the RHS of the formula).

With those changes incorporated, this will work:

model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")

make sure """ comments are only a tab away and not 5 spaces

You can use .resize() to get every time the width/height actually changes, like this:

$(window).resize(function() {
  //resize just happened, pixels changed
});

You can view a working demo here, it takes the new height/width values and updates them in the page for you to see. Remember the event doesn't really start or end, it just "happens" when a resize occurs...there's nothing to say another one won't happen.

Edit: By comments it seems you want something like a "on-end" event, the solution you found does this, with a few exceptions (you can't distinguish between a mouse-up and a pause in a cross-browser way, the same for an end vs a pause). You can create that event though, to make it a bit cleaner, like this:

$(window).resize(function() {
    if(this.resizeTO) clearTimeout(this.resizeTO);
    this.resizeTO = setTimeout(function() {
        $(this).trigger('resizeEnd');
    }, 500);
});

You could have this is a base file somewhere, whatever you want to do...then you can bind to that new resizeEnd event you're triggering, like this:

$(window).bind('resizeEnd', function() {
    //do something, window hasn't changed size in 500ms
});

You can see a working demo of this approach here ?

The reason may be that watcher is declared as local variable to a method and it is garbage collected when the method finishes. You should declare it as a class member. Try the following:

FileSystemWatcher watcher;

private void watch()
{
  watcher = new FileSystemWatcher();
  watcher.Path = path;
  watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
                         | NotifyFilters.FileName | NotifyFilters.DirectoryName;
  watcher.Filter = "*.*";
  watcher.Changed += new FileSystemEventHandler(OnChanged);
  watcher.EnableRaisingEvents = true;
}

private void OnChanged(object source, FileSystemEventArgs e)
{
  //Copies file to another directory.
}

Here's my spin on how to get the difference in days between two dates with PHP. Note the use of '!' in the format to discard the time part of the dates, thanks to info from DateTime createFromFormat without time.

$today = DateTime::createFromFormat('!Y-m-d', date('Y-m-d'));
$wanted = DateTime::createFromFormat('!d-m-Y', $row["WANTED_DELIVERY_DATE"]);
$diff = $today->diff($wanted);
$days = $diff->days;
if (($diff->invert) != 0) $days = -1 * $days;
$overdue = (($days < 0) ? true : false);
print "<!-- (".(($days > 0) ? '+' : '').($days).") -->\n";

I came across a situation in which I had to send a long message as part of a command argument and had to adhere to the line length limitation. The commands looks something like this:

somecommand --message="I am a long message" args

The way I solved this is to move the message out as a here document (like @tripleee suggested). But a here document becomes a stdin, so it needs to be read back in, I went with the below approach:

message=$(
    tr "\n" " " <<- END
        This is a
        long message
END
)
somecommand --message="$message" args

This has the advantage that $message can be used exactly as the string constant with no extra whitespace or line breaks.

Note that the actual message lines above are prefixed with a tab character each, which is stripped by here document itself (because of the use of <<-). There are still line breaks at the end, which are then replaced by dd with spaces.

Note also that if you don't remove newlines, they will appear as is when "$message" is expanded. In some cases, you may be able to workaround by removing the double-quotes around $message, but the message will no longer be a single argument.

This counts the rows of the inner query:

select count(*) from (
    select count(SID) 
    from Test 
    where Date = '2012-12-10' 
    group by SID
) t

However, in this case the effect of that is the same as this:

select count(distinct SID) from Test where Date = '2012-12-10'

I would add this as a comment to the other good answers, but I need more reputation to do so. Be sure to allow for scientific notation if necessary, i.e. 3e4 = 30000. This is default behavior in many languages. I found the following regex to work:

/^[-+]?\d+([Ee][+-]?\d+)?$/;
//          ^^              If 'e' is present to denote exp notation, get it
//             ^^^^^          along with optional sign of exponent
//                  ^^^       and the exponent itself
//        ^            ^^     The entire exponent expression is optional

This is what I did:

EF:

using (var context = new SomeDBContext())
{
    foreach (var item in model.ShopItems)  // ShopItems is a posted list with values 
    {    
        var feature = context.Shop
                             .Where(h => h.ShopID == 123 && h.Type == item.Type).ToList();

        feature.ForEach(a => a.SortOrder = item.SortOrder);

# Let us consider the following typical mysql backup script:
mysqldump --routines --no-data -h $mysqlHost -P $mysqlPort -u $mysqlUser -p$mysqlPassword $database

# It succeeds but stderr will get:
# Warning: Using a password on the command line interface can be insecure.
# You can fix this with the below hack:
credentialsFile=/mysql-credentials.cnf
echo "[client]" > $credentialsFile
echo "user=$mysqlUser" >> $credentialsFile
echo "password=$mysqlPassword" >> $credentialsFile

I found an example from @progress/kendo-data-query in file filter-descriptor.interface.d.ts

Checker

declare const isCompositeFilterDescriptor: (source: FilterDescriptor | CompositeFilterDescriptor) => source is CompositeFilterDescriptor;

Example usage

const filters: Array<FilterDescriptor | CompositeFilterDescriptor> = filter.filters;

filters.forEach((element: FilterDescriptor | CompositeFilterDescriptor) => {
    if (isCompositeFilterDescriptor(element)) {
        // element type is CompositeFilterDescriptor
    } else {
        // element type is FilterDescriptor
    }
});

You can also encode bytes to Base64. How to get this from a stream see here: How to convert an Stream into a byte[] in C#?

Or I think it should be also possible to use the .ToString() method and encode this.

This cross-browser lib seems safer - just zoom and moz-transform won't cover as many browsers as jquery.transform2d's scale().

http://louisremi.github.io/jquery.transform.js/

For example

$('#div').css({ transform: 'scale(.5)' });

Update

OK - I see people are voting this down without an explanation. The other answer here won't work in old Safari (people running Tiger), and it won't work consistently in some older browsers - that is, it does scale things but it does so in a way that's either very pixellated or shifts the position of the element in a way that doesn't match other browsers.

Or just look at this question, which this one is likely just a dupe of:

Here's my one liner for positive integers, based on this answer:

usage:

(-7).Mod(3); // returns 2

implementation:

static int Mod(this int a, int n) => (((a %= n) < 0) ? n : 0) + a;

I am using Tortoise SVN client. You can alternativley check out the required project from SVN in some folder. You can see a .SVN folder inside the project. Copy the .SVN folder into the workspace folder. Now remove the project from eclipse and import the same again into eclipse. You can see now the project is now associated with svn

The difference between them is, that a val is executed when it is defined whereas a lazy val is executed when it is accessed the first time.

scala> val x = { println("x"); 15 }
x
x: Int = 15

scala> lazy val y = { println("y"); 13 }
y: Int = <lazy>

scala> x
res2: Int = 15

scala> y
y
res3: Int = 13

scala> y
res4: Int = 13

In contrast to a method (defined with def) a lazy val is executed once and then never again. This can be useful when an operation takes long time to complete and when it is not sure if it is later used.

scala> class X { val x = { Thread.sleep(2000); 15 } }
defined class X

scala> class Y { lazy val y = { Thread.sleep(2000); 13 } }
defined class Y

scala> new X
res5: X = X@262505b7 // we have to wait two seconds to the result

scala> new Y
res6: Y = Y@1555bd22 // this appears immediately

Here, when the values x and y are never used, only x unnecessarily wasting resources. If we suppose that y has no side effects and that we do not know how often it is accessed (never, once, thousands of times) it is useless to declare it as def since we don't want to execute it several times.

If you want to know how lazy vals are implemented, see this question.

This gets part way there. There is no ActualFontSize property but there is an ActualHeight and that would relate to the FontSize. Right now this only sizes for the original render. I could not figure out how to register the Converter as resize event. Actually maybe need to register the FontSize as a resize event. Please don't mark me down for an incomplete answer. I could not put code sample in a comment.

You should use Comparable instead of a Comparator if a default sort is what your looking for.

See here, this may be of some help - When should a class be Comparable and/or Comparator?

Try this -

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class TestSort {

    public static void main(String args[]){

        ToSort toSort1 = new ToSort(new Float(3), "3");
        ToSort toSort2 = new ToSort(new Float(6), "6");
        ToSort toSort3 = new ToSort(new Float(9), "9");
        ToSort toSort4 = new ToSort(new Float(1), "1");
        ToSort toSort5 = new ToSort(new Float(5), "5");
        ToSort toSort6 = new ToSort(new Float(0), "0");
        ToSort toSort7 = new ToSort(new Float(3), "3");
        ToSort toSort8 = new ToSort(new Float(-3), "-3");

        List<ToSort> sortList = new ArrayList<ToSort>();
        sortList.add(toSort1);
        sortList.add(toSort2);
        sortList.add(toSort3);
        sortList.add(toSort4);
        sortList.add(toSort5);
        sortList.add(toSort6);
        sortList.add(toSort7);
        sortList.add(toSort8);

        Collections.sort(sortList);

        for(ToSort toSort : sortList){
            System.out.println(toSort.toString());
        }
    }

}

public class ToSort implements Comparable<ToSort> {

    private Float val;
    private String id;

    public ToSort(Float val, String id){
        this.val = val;
        this.id = id;
    }

    @Override
    public int compareTo(ToSort f) {

        if (val.floatValue() > f.val.floatValue()) {
            return 1;
        }
        else if (val.floatValue() <  f.val.floatValue()) {
            return -1;
        }
        else {
            return 0;
        }

    }

    @Override
    public String toString(){
        return this.id;
    }
}

You can use the following to parse a string to an integer:

int value=Integer.parseInt(textView.getText().toString());

(1) input: 12 then it will work.. because textview has taken this 12 number as "12" string.

(2) input: "abdul" then it will throw an exception that is NumberFormatException. So to solve this we need to use try catch as I have mention below:

  int tax_amount=20;
  EditText edit=(EditText)findViewById(R.id.editText1);
     try
       {

        int value=Integer.parseInt(edit.getText().toString());
        value=value+tax_amount;
        edit.setText(String.valueOf(value));// to convert integer to string 

       }catch(NumberFormatException ee){
       Log.e(ee.toString());
       }

seems like opening a new session is the key.

see this answer.

and here is an awesome explanation about this error

next() does not work in your case because you first call readlines() which basically sets the file iterator to point to the end of file.

Since you are reading in all the lines anyway you can refer to the next line using an index:

filne = "in"
with open(filne, 'r+') as f:
    lines = f.readlines()
    for i in range(0, len(lines)):
        line = lines[i]
        print line
        if line[:5] == "anim ":
            ne = lines[i + 1] # you may want to check that i < len(lines)
            print ' ne ',ne,'\n'
            break

I had the same sittuation , I had many buttongroup insite my item on listview and I was changing some boolean values inside my item like holder.rbVar.setOnclik...

my problem occured because I was calling a method inside getView(); and was saving an object inside sharepreference, so I had same error above

How I solved it; I removed my method inside getView() to notifyDataSetInvalidated() and problem gone

   @Override
    public void notifyDataSetChanged() {
        saveCurrentTalebeOnShare(currentTalebe);
        super.notifyDataSetChanged();
    }

Just want to point out you do not need to specify all dimensions of the array.

The leftmost dimension can be 'guessed' by the compiler.

#include <stdio.h>
int main(void) {
  int arr[][5] = {{1,2,3,4,5}, {5,6,7,8,9}, {6,5,4,3,2}};
  printf("sizeof arr is %d bytes\n", (int)sizeof arr);
  printf("number of elements: %d\n", (int)(sizeof arr/sizeof arr[0]));
  return 0;
}

What I do is I want the page to stay after submit when there are errors...So I want the page to be reloaded :

($_SERVER["PHP_SELF"])

While I include the sript from a seperate file e.g

include_once "test.php";

I also read somewhere that

if(isset($_POST['submit']))

Is a beginners old fasion way of posting a form, and

if ($_SERVER['REQUEST_METHOD'] == 'POST')

Should be used (Not my words, read it somewhere)

If you have access to a compiler that supports variadic templates, you can use this:

#include <iostream>
#include <string>
#include <algorithm>

template<char ... CharacterList>
inline bool check_characters(char c) {
    char match_characters[sizeof...(CharacterList)] = { CharacterList... };
    for(int i = 0; i < sizeof...(CharacterList); ++i) {
        if(c == match_characters[i]) {
            return true;
        }
    }
    return false;
}

template<char ... CharacterList>
inline void strip_characters(std::string & str) {
    str.erase(std::remove_if(str.begin(), str.end(), &check_characters<CharacterList...>), str.end());
}

int main()
{
    std::string str("(555) 555-5555");
    strip_characters< '(',')','-' >(str);
    std::cout << str << std::endl;
}

Similar to Ray's answer above, Hive View 2.0 in Hortonworks Data Platform also allows you to run a Hive query and then save the output as csv.

assuming both elements have 50% width, here is what i used:

css:

  .parent {
    width: 100%;
    display: flex;
  }  
  .child-1 {
    width: 50%;
    margin-right: -50%;
    margin-left: 50%;
    background: #ff0;
  }
  .child-2 {
    width: 50%;
    margin-right: 50%;
    margin-left: -50%;
    background: #0f0;
  }

html:

<div class="parent">
  <div class="child-1">child1</div>
  <div class="child-2">child2</div>
</div>

example: https://jsfiddle.net/gzveri/o6umhj53/

btw, this approach works for any 2 nearby elements in a long list of elements. For example I have a long list of elements with 2 items per row and I want each 3-rd and 4-th element in the list to be swapped, so that it renders elements in a chess style, then I use these rules:

  .parent > div:nth-child(4n+3) {
    margin-right: -50%;
    margin-left: 50%;
  }
  .parent > div:nth-child(4n+4) {
    margin-right: 50%;
    margin-left: -50%;
  }

The query component is indicated by the first ? in a URI. "Query string" might be a synonym (this term is not used in the URI standard).

Some examples for HTTP URIs with query components:

http://example.com/foo?bar
http://example.com/foo/foo/foo?bar/bar/bar
http://example.com/?bar
http://example.com/?@bar._=???/1:
http://example.com/?bar1=a&bar2=b

(list of allowed characters in the query component)

The "format" of the query component is up to the URI authors. A common convention (but nothing more than a convention, as far as the URI standard is concerned¹) is to use the query component for key-value pairs, aka. parameters, like in the last example above: bar1=a&bar2=b.

Such parameters could also appear in the other URI components, i.e., the path² and the fragment. As far as the URI standard is concerned, it’s up to you which component and which format to use.

Example URI with parameters in the path, the query, and the fragment:

http://example.com/foo;key1=value1?key2=value2#key3=value3

¹ The URI standard says about the query component:

[…] query components are often used to carry identifying information in the form of "key=value" pairs […]

² The URI standard says about the path component:

[…] the semicolon (";") and equals ("=") reserved characters are often used to delimit parameters and parameter values applicable to that segment. The comma (",") reserved character is often used for similar purposes.

That's an easy one:

[aView convertPoint:localPosition toView:nil];

... converts a point in local coordinate space to window coordinates. You can use this method to calculate a view's origin in window space like this:

[aView.superview convertPoint:aView.frame.origin toView:nil];

2014 Edit: Looking at the popularity of Matt__C's comment it seems reasonable to point out that the coordinates...

1. don't change when rotating the device.
2. always have their origin in the top left corner of the unrotated screen.
3. are window coordinates: The coordinate system ist defined by the bounds of the window. The screen's and device coordinate systems are different and should not be mixed up with window coordinates.

Be aware that classes that descend from NumberFormat (and most other Format descendants) are not synchronized. It is a common (but dangerous) practice to create format objects and store them in static variables in a util class. In practice, it will pretty much always work until it starts experiencing significant load.

Just want to point out that in case you have a MemoryStream you already have memorystream.ToArray() for that.

Also, if you are dealing with streams of unknown or different subtypes and you can receive a MemoryStream, you can relay on said method for those cases and still use the accepted answer for the others, like this:

public static byte[] StreamToByteArray(Stream stream)
{
    if (stream is MemoryStream)
    {
        return ((MemoryStream)stream).ToArray();                
    }
    else
    {
        // Jon Skeet's accepted answer 
        return ReadFully(stream);
    }
}

function stringToDate(_date,_format,_delimiter)
{
            var formatLowerCase=_format.toLowerCase();
            var formatItems=formatLowerCase.split(_delimiter);
            var dateItems=_date.split(_delimiter);
            var monthIndex=formatItems.indexOf("mm");
            var dayIndex=formatItems.indexOf("dd");
            var yearIndex=formatItems.indexOf("yyyy");
            var month=parseInt(dateItems[monthIndex]);
            month-=1;
            var formatedDate = new Date(dateItems[yearIndex],month,dateItems[dayIndex]);
            return formatedDate;
}

stringToDate("17/9/2014","dd/MM/yyyy","/");
stringToDate("9/17/2014","mm/dd/yyyy","/")
stringToDate("9-17-2014","mm-dd-yyyy","-")

JQuery 1.5 introduces promises, and here's the simplest implementation I've seen to control order of execution. Full documentation at http://api.jquery.com/jquery.when/

$.when( $('#myDiv').css('background-color', 'red') )
 .then( alert('hi!') )
 .then( myClickFunction( $('#myID') ) )
 .then( myThingToRunAfterClick() );

The solution that i believe is best and optimized is:

try:
   #your code
except "ModelName".DoesNotExist:
   #your code

or an ORACLE version:

delete
  from table_name
 where trunc(table_name.date) > to_date('01/01/2009','mm/dd/yyyy') 

if you have error in Sqlite built in python you can use Conda to solve this conflict

In my case it was best to calculate this in SQL Server, since i wanted to take current location and then search for all zip codes within a certain distance from current location. I also had a DB which contained a list of zip codes and their lat longs. Cheers

It may be that it's not loading the template you expect. I added a new class that inherited from UpdateView - I thought it would automatically pick the template from what I named my class, but it actually loaded it based on the model property on the class, which resulted in another (wrong) template being loaded. Once I explicitly set template_name for the new class, it worked fine.

If you are a windows user and try to start py-script in cmd - don't forget to type python before filename.

I have "No module named google" error if forget to type it.

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

public void swapnumber(int a,int b){
    a = a+b-(b=a);
    System.out.println("a = "+a +" b= "+b);
}

In case you need it as a Class, you can extend it with dict and use update method:

Class a(dict):
  # some stuff
  self.update(b)

Please use json.Decoder instead of json.Unmarshal.

func test(rw http.ResponseWriter, req *http.Request) {
    decoder := json.NewDecoder(req.Body)
    var t test_struct
    err := decoder.Decode(&t)
    if err != nil {
        panic(err)
    }
    log.Println(t.Test)
}

This is an exact fix to your problem, but I would advise against initializing the matrix with a default value that represents '0' or 'undefined', as Arrays in javascript are just regular objects, so you wind up wasting effort. If you want to default the cells to some meaningful value, then this snippet will work well, but if you want an uninitialized matrix, don't use this version:

/**
* Generates a matrix (ie: 2-D Array) with: 
* 'm' columns, 
* 'n' rows, 
* every cell defaulting to 'd';
*/
function Matrix(m, n, d){
    var mat = Array.apply(null, new Array(m)).map(
        Array.prototype.valueOf,
        Array.apply(null, new Array(n)).map(
            function() {
               return d;
            }
        )
    );
    return mat;
}

Usage:

< Matrix(3,2,'dobon');
> Array [ Array['dobon', 'dobon'], Array['dobon', 'dobon'], Array['dobon', 'dobon'] ]

If you would rather just create an uninitialized 2-D Array, then this will be more efficient than unnecessarily initializing every entry:

/**
* Generates a matrix (ie: 2-D Array) with: 
* 'm' columns, 
* 'n' rows, 
* every cell remains 'undefined';
*/
function Matrix(m, n){
    var mat = Array.apply(null, new Array(m)).map(
        Array.prototype.valueOf,
        new Array(n)
    );
    return mat;
}

Usage:

< Matrix(3,2);
> Array [ Array[2], Array[2], Array[2] ]

Make JAVA_HOME variable point to a jdk installation, not jre.

You are referencing the runtime environment, not the development kit - it can't find the compiler because its not there.

From the line you posted, which states you have open-jdk you can just remove the jre at end:

export JAVA_HOME='/usr/lib/jvm/java-6-openjdk/'

You need to use quote marks.

font-family: "Comic Sans MS", cursive, sans-serif;

Although you really really shouldn't use comic sans. The font has massive stigma attached to it's use; it's not seen as professional at all.

The variable '$$' contains the PID.

I had the same problem and resolved by pressing Ctrl + R , Ctrl + W.

First Question: Difference between parseInt and valueOf in java?

Second Question:

NumberFormat format = NumberFormat.getInstance(Locale.FRANCE);
Number number = format.parse("1,234");
double d = number.doubleValue();

Third Question:

DecimalFormat df = new DecimalFormat();
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setDecimalSeparator('.');
symbols.setGroupingSeparator(',');
df.setDecimalFormatSymbols(symbols);
df.parse(p);

I also wanted to know why 2 GAC and found the following explanation by Mark Miller in the comments section of .NET 4.0 has 2 Global Assembly Cache (GAC):

Mark Miller said... June 28, 2010 12:13 PM

Thanks for the post. "Interference issues" was intentionally vague. At the time of writing, the issues were still being investigated, but it was clear there were several broken scenarios.

For instance, some applications use Assemby.LoadWithPartialName to load the highest version of an assembly. If the highest version was compiled with v4, then a v2 (3.0 or 3.5) app could not load it, and the app would crash, even if there were a version that would have worked. Originally, we partitioned the GAC under it's original location, but that caused some problems with windows upgrade scenarios. Both of these involved code that had already shipped, so we moved our (version-partitioned GAC to another place.

This shouldn't have any impact to most applications, and doesn't add any maintenance burden. Both locations should only be accessed or modified using the native GAC APIs, which deal with the partitioning as expected. The places where this does surface are through APIs that expose the paths of the GAC such as GetCachePath, or examining the path of mscorlib loaded into managed code.

It's worth noting that we modified GAC locations when we released v2 as well when we introduced architecture as part of the assembly identity. Those added GAC_MSIL, GAC_32, and GAC_64, although all still under %windir%\assembly. Unfortunately, that wasn't an option for this release.

Hope it helps future readers.

You can change your code to this:

$where_au = "(library.available_until >= '{date('Y-m-d H:i:s)}' OR library.available_until = '00-00-00 00:00:00')";
$this->db
    ->select('*')
    ->from('library')
    ->where('library.rating >=', $form['slider'])
    ->where('library.votes >=', '1000')
    ->where('library.language !=', 'German')
    ->where($where_au)
    ->where('library.release_year >=', $year_start)
    ->where('library.release_year <=', $year_end)
    ->join('rating_repo', 'library.id = rating_repo.id');

Tip: to watch the generated query you can use

echo $this->db->last_query(); die();

The documentation you linked actually has the answer in the link associated with the "Java class located out of the source root." Configure your source and test roots and it should work.

https://www.jetbrains.com/idea/webhelp/configuring-content-roots.html

Since you stated that these are tests you should probably go with them marked as Test Source Root instead of Source Root.

For Python 3

Remove the rb argument and use either r or don't pass argument (default read mode).

with open( <path-to-file>, 'r' ) as theFile:
    reader = csv.DictReader(theFile)
    for line in reader:
        # line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
        # e.g. print( line[ 'workers' ] ) yields 'w0'
        print(line)

For Python 2

import csv
with open( <path-to-file>, "rb" ) as theFile:
    reader = csv.DictReader( theFile )
    for line in reader:
        # line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
        # e.g. print( line[ 'workers' ] ) yields 'w0'

Python has a powerful built-in CSV handler. In fact, most things are already built in to the standard library.

On Windows, there are two differences between mutexes and binary semaphores:

1. A mutex can only be released by the thread which has ownership, i.e. the thread which previously called the Wait function, (or which took ownership when creating it). A semaphore can be released by any thread.

2. A thread can call a wait function repeatedly on a mutex without blocking. However, if you call a wait function twice on a binary semaphore without releasing the semaphore in between, the thread will block.

Fixed version of java's Integer.parseInt(text) to work with negative numbers:

public static int parseInt(String binary) {
    if (binary.length() < Integer.SIZE) return Integer.parseInt(binary, 2);

    int result = 0;
    byte[] bytes = binary.getBytes();

    for (int i = 0; i < bytes.length; i++) {
        if (bytes[i] == 49) {
            result = result | (1 << (bytes.length - 1 - i));
        }
    }

    return result;
}

Pass param rot=0 to rotate the xticks:

import matplotlib
matplotlib.style.use('ggplot')
import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ 'celltype':["foo","bar","qux","woz"], 's1':[5,9,1,7], 's2':[12,90,13,87]})
df = df[["celltype","s1","s2"]]
df.set_index(["celltype"],inplace=True)
df.plot(kind='bar',alpha=0.75, rot=0)
plt.xlabel("")
plt.show()

yields plot:

I have found the mistake what I did. We need to get the activity instance from the override method OnAttach() For example,

public MainActivity activity;

@Override
public void onAttach(Activity activity){
    this.activity = activity;
}

Then pass the activity as context as following.

Intent mIntent = new Intent(activity, MusicHome.class);

It's possible to utilize custom command line options in Gradle to end up with something like:

./gradlew printPet --pet="puppies!"

However, custom command line options in Gradle are an incubating feature.

Java solution

To end up with something like this follow the instructions here:

import org.gradle.api.tasks.options.Option;

public class PrintPet extends DefaultTask {
    private String pet;

    @Option(option = "pet", description = "Name of the cute pet you would like to print out!")
    public void setPet(String pet) {
        this.pet = pet;
    }

    @Input
    public String getPet() {
        return pet;
    }

    @TaskAction
    public void print() {
        getLogger().quiet("'{}' are awesome!", pet);
    }
}

Then register it:

task printPet(type: PrintPet)

Now you can do:

./gradlew printPet --pet="puppies"

output:

Puppies! are awesome!

Kotlin solution

open class PrintPet : DefaultTask() {

    @Suppress("UnstableApiUsage")
    @set:Option(option = "pet", description = "The cute pet you would like to print out")
    @get:Input
    var pet: String = ""

    @TaskAction
    fun print() {    
        println("$pet are awesome!")
    }
}

then register the task with:

tasks.register<PrintPet>("printPet")

onNewIntent() is meant as entry point for singleTop activities which already run somewhere else in the stack and therefore can't call onCreate(). From activities lifecycle point of view it's therefore needed to call onPause() before onNewIntent(). I suggest you to rewrite your activity to not use these listeners inside of onNewIntent(). For example most of the time my onNewIntent() methods simply looks like this:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // getIntent() should always return the most recent
    setIntent(intent);
}

With all setup logic happening in onResume() by utilizing getIntent().

Give this solution a try

Works best in most of the cases

you may have to use div instead of li for that

.DivParent {_x000D_
    height: 100px;_x000D_
    border: 1px solid lime;_x000D_
    white-space: nowrap;_x000D_
}_x000D_
.verticallyAlignedDiv {_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
    white-space: normal;_x000D_
}_x000D_
.DivHelper {_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
    height:100%;_x000D_
}

<div class="DivParent">_x000D_
    <div class="verticallyAlignedDiv">_x000D_
        <p>Isnt it good!</p>_x000D_
     _x000D_
    </div><div class="DivHelper"></div>_x000D_
</div>

You just add following lines of code in style.xml file

<style name="AppTheme.NoTitleBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>

change apptheme in AndroidManifest.xml file

android:theme="@style/AppTheme.NoTitleBar"

You forgot to declare double as a return type

public double diameter()
{
    double d = radius * 2;
    return d;
}

You have to validate the connection.

If you use Oracle it is likely that you use Oracle´s Universal Connection Pool. The following assumes that you do so.

The easiest way to validate the connection is to tell Oracle that the connection must be validated while borrowing it. This can be done with

pool.setValidateConnectionOnBorrow(true);

But it works only if you hold the connection for a short period. If you borrow the connection for a longer time, it is likely that the connection gets broken while you hold it. In that case you have to validate the connection explicitly with

if (connection == null || !((ValidConnection) connection).isValid())

See the Oracle documentation for further details.

Need to make sure once switched into a frame, need to switch back to default content for accessing webelements in another frames. As Webdriver tend to find the new frame inside the current frame.

driver.switchTo().defaultContent()

It's impossible if the method is declared in the derived class as overrides. to do that, the method in the derived class should be declared as new:

public class Base {

    public virtual string X() {
        return "Base";
    }
}
public class Derived1 : Base
{
    public new string X()
    {
        return "Derived 1";
    }
}

public class Derived2 : Base 
{
    public override string X() {
        return "Derived 2";
    }
}

Derived1 a = new Derived1();
Base b = new Derived1();
Base c = new Derived2();
a.X(); // returns Derived 1
b.X(); // returns Base
c.X(); // returns Derived 2

See fiddle here

How about select cast(cast my_datetime_field as date) as datetime)? This results in the same date, with the time set to 00:00, but avoids any conversion to text and also avoids any explicit numeric rounding.

Problem is when you already have an outline. Chrome still changes something and it's a real pain. I cannot find what to change :

.search input {
  outline: .5em solid black;
  width:41%;
  background-color:white;
  border:none;
  font-size:1.4em;
  padding: 0 0.5em 0 0.5em;
  border-radius:3px;
  margin:0;
  height:2em;
}

.search input:focus, .search input:hover {
  outline: .5em solid black !important;
  box-shadow:none;
  border-color:transparent;;
 }

.search button {
  border:none;
  outline: .5em solid black;
  color:white;
  font-size:1.4em;
  padding: 0 0.9em 0 0.9em;
  border-radius: 3px;
  margin:0;
  height:2em;
  background: -webkit-gradient(linear, left top, left bottom, from(#4EB4F8), to(#4198DE));
  background: -webkit-linear-gradient(#4EB4F8, #4198DE);
  background: -moz-linear-gradient(top, #4EB4F8, #4198DE);
  background: -ms-linear-gradient(#4EB4F8, #4198DE);
  background: -o-linear-gradient(#4EB4F8, #4198DE);
  background: linear-gradient(#4EB4F8, #4198DE);
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#4EB4F8', endColorstr='#4198DE');
  zoom: 1;
}

For those who can't (or don't want to) setup a debugger to track down the original exception which was causing the rollback-flag to get set, you can just add a bunch of debug statements throughout your code to find the lines of code which trigger the rollback-only flag:

logger.debug("Is rollbackOnly: " + TransactionAspectSupport.currentTransactionStatus().isRollbackOnly());

Adding this throughout the code allowed me to narrow down the root cause, by numbering the debug statements and looking to see where the above method goes from returning "false" to "true".

Swift 5 Solution

You can try out this implementation for running Swift 5 on XCode 11

class CustomView: UIView {

    var customParam: customType
    
    var container = UIView()
    
    required init(customParamArg: customType) {
        self.customParam = customParamArg
        super.init(frame: .zero)
        // Setting up the view can be done here
        setupView()
    }

    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    

    func setupView() {
        // Can do the setup of the view, including adding subviews

        setupConstraints()
    }
    
    func setupConstraints() {
        // setup custom constraints as you wish
    }
    
    
}

Based on Daren's excellent answer, note that this code can be shortened significantly by using the appropriate XslCompiledTransform.Transform overload:

var myXslTrans = new XslCompiledTransform(); 
myXslTrans.Load("stylesheet.xsl"); 
myXslTrans.Transform("source.xml", "result.html"); 

(Sorry for posing this as an answer, but the code block support in comments is rather limited.)

In VB.NET, you don't even need a variable:

With New XslCompiledTransform()
    .Load("stylesheet.xsl")
    .Transform("source.xml", "result.html")
End With

Just in case someone else comes across this, to clarify the answer `n is grave accent n, not single tick n

The override keyword serves two purposes:

1. It shows the reader of the code that "this is a virtual method, that is overriding a virtual method of the base class."
2. The compiler also knows that it's an override, so it can "check" that you are not altering/adding new methods that you think are overrides.

To explain the latter:

class base
{
  public:
    virtual int foo(float x) = 0; 
};


class derived: public base
{
   public:
     int foo(float x) override { ... } // OK
}

class derived2: public base
{
   public:
     int foo(int x) override { ... } // ERROR
};

In derived2 the compiler will issue an error for "changing the type". Without override, at most the compiler would give a warning for "you are hiding virtual method by same name".

You could whip up a little helper function to do this:

/**
 * Determines if $number is between $min and $max
 *
 * @param  integer  $number     The number to test
 * @param  integer  $min        The minimum value in the range
 * @param  integer  $max        The maximum value in the range
 * @param  boolean  $inclusive  Whether the range should be inclusive or not
 * @return boolean              Whether the number was in the range
 */
function in_range($number, $min, $max, $inclusive = FALSE)
{
    if (is_int($number) && is_int($min) && is_int($max))
    {
        return $inclusive
            ? ($number >= $min && $number <= $max)
            : ($number > $min && $number < $max) ;
    }

    return FALSE;
}

And you would use it like so:

var_dump(in_range(5, 0, 10));        // TRUE
var_dump(in_range(1, 0, 1));         // FALSE
var_dump(in_range(1, 0, 1, TRUE));   // TRUE
var_dump(in_range(11, 0, 10, TRUE)); // FALSE

// etc...

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

you can use BehaviourSubject as described above or there is one more way:

you can handle EventEmitter like this: first add a selector

import {Component, Output, EventEmitter} from 'angular2/core';

@Component({
// other properties left out for brevity
selector: 'app-nav-component', //declaring selector
template:`
  <div class="nav-item" (click)="selectedNavItem(1)"></div>
`
 })

 export class Navigation {

@Output() navchange: EventEmitter<number> = new EventEmitter();

selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navchange.emit(item)
}

}

Now you can handle this event like let us suppose observer.component.html is the view of Observer component

<app-nav-component (navchange)="recieveIdFromNav($event)"></app-nav-component>

then in the ObservingComponent.ts

export class ObservingComponent {

 //method to recieve the value from nav component

 public recieveIdFromNav(id: number) {
   console.log('here is the id sent from nav component ', id);
 }

 }

Well, you're going to have to check for null somewhere. You could do something like this:

from item in db.vw_Dropship_OrderItems
         where (listStatus == null || listStatus.Contains(item.StatusCode)) 
            && (listMerchants == null || listMerchants.Contains(item.MerchantId))
         select item;

I didn't find an answer that satisfied me, so I wrote one myself, I think it is easy to understand and implement and suitable for all situations.

    transposeArray: function (mat) {
        let newMat = [];
        for (let j = 0; j < mat[0].length; j++) {  // j are columns
            let temp = [];
            for (let i = 0; i < mat.length; i++) {  // i are rows
                temp.push(mat[i][j]);  // so temp will be the j(th) column in mat
            }
            newMat.push(temp);  // then just push every column in newMat
        }
        return newMat;
    }

You can loop through the columns collection of the datatable.

VB

Dim dt As New DataTable()
For Each column As DataColumn In dt.Columns
    Console.WriteLine(column.ColumnName)
Next

C#

DataTable dt = new DataTable();
foreach (DataColumn column in dt.Columns)
{
Console.WriteLine(column.ColumnName);
}

Hope this helps!

Use:

Target= "_blank" property of anchor tag

JDBC is the predecessor of JPA.

JDBC is a bridge between the Java world and the databases world. In JDBC you need to expose all dirty details needed for CRUD operations, such as table names, column names, while in JPA (which is using JDBC underneath), you also specify those details of database metadata, but with the use of Java annotations.

So JPA creates update queries for you and manages the entities that you looked up or created/updated (it does more as well).

If you want to do JPA without a Java EE container, then Spring and its libraries may be used with the very same Java annotations.

Keep the viewport untouched: <meta name="viewport" content="width=device-width, initial-scale=1.0">

Assuming you would like to achieve the effect of a continuous black bar to the right side: #menubar shouldn't exceed 100%, adjust the border radius such that the right side is squared and adjust the padding so that it extends a little more to the right. Modify the following to your #menubar:

border-radius: 30px 0px 0px 30px;
width: 100%; /*setting to 100% would leave a little space to the right */
padding: 0px 0px 0px 10px; /*fills the little gap*/

Adjusting the padding to 10px of course leaves the left menu to the edge of the bar, you can put the remaining 40px to each of the li, 20px on each side left and right:

.menuitem {
display: block;
padding: 0px 20px;
}

When you resize the browser smaller, you would find still the white background: place your background texture instead from your div to body. Or alternatively, adjust the navigation menu width from 100% to lower value using media queries. There are a lot of adjustments to be made to your code to create a proper layout, I'm not sure what you intend to do but the above code will somehow fix your overflowing bar.

A DataFrame is an RDD that has a schema. You can think of it as a relational database table, in that each column has a name and a known type. The power of DataFrames comes from the fact that, when you create a DataFrame from a structured dataset (Json, Parquet..), Spark is able to infer a schema by making a pass over the entire (Json, Parquet..) dataset that's being loaded. Then, when calculating the execution plan, Spark, can use the schema and do substantially better computation optimizations. Note that DataFrame was called SchemaRDD before Spark v1.3.0

@echo off 
    setlocal enableextensions disabledelayedexpansion

    set "search=%1"
    set "replace=%2"

    set "textFile=Input.txt"

    for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
        set "line=%%i"
        setlocal enabledelayedexpansion
        >>"%textFile%" echo(!line:%search%=%replace%!
        endlocal
    )

for /f will read all the data (generated by the type comamnd) before starting to process it. In the subprocess started to execute the type, we include a redirection overwritting the file (so it is emptied). Once the do clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.

You'll want something like this, taken from http://www.howtocreate.co.uk/tutorials/javascript/browserwindow

function alertSize() {
  var myWidth = 0, myHeight = 0;
  if( typeof( window.innerWidth ) == 'number' ) {
    //Non-IE
    myWidth = window.innerWidth;
    myHeight = window.innerHeight;
  } else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
    //IE 6+ in 'standards compliant mode'
    myWidth = document.documentElement.clientWidth;
    myHeight = document.documentElement.clientHeight;
  } else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
    //IE 4 compatible
    myWidth = document.body.clientWidth;
    myHeight = document.body.clientHeight;
  }
  window.alert( 'Width = ' + myWidth );
  window.alert( 'Height = ' + myHeight );
}

So that's innerHeight for modern browsers, documentElement.clientHeight for IE, body.clientHeight for deprecated/quirks.

I've put this answer on a similar question that was marked as a duplicate of this question. The answer has helped a decent amount of people so I thought I'd add it here too in just in case.

This doesn't exactly answer the question but for anyone using AngularJS trying to achieve this, the answer is slightly different. And actually the normal answer won't work (at least it didn't for me).

Your html will look pretty similar to the normal radio button:

<input type='radio' name='group' ng-model='mValue' value='first' />First
<input type='radio' name='group' ng-model='mValue' value='second' /> Second

In your controller you'll have declared the mValue that is associated with the radio buttons. To have one of these radio buttons preselected, assign the $scope variable associated with the group to the desired input's value:

$scope.mValue="second"

This makes the "second" radio button selected on loading the page.

Null refers to an absence of data. Null is formally defined as a value that is unavailable, unassigned, unknown or inapplicable (OCA Oracle Database 12c, SQL Fundamentals I Exam Guide, p87). So, you may not see records with columns containing null values when said columns are restricted using an "in" or "not in" clauses.

You need to take out a float: left; property... because when you use float the parent div do not grub the height of it's children... If you want the parent dive to get the children height you need to give to the parent div a css property overflow:hidden; But to solve your problem you can use display: table-cell; instead of float... it will automatically scale the div height to its parent height...

Starting from Scala 3, there is now enum keyword which can represent a set of constants (and other use cases)

enum Color:
   case Red, Green, Blue

scala> val red = Color.Red
val red: Color = Red
scala> red.ordinal
val res0: Int = 0

Try accessing the placeholder attribute of the input and change its value like the following:

$('#some_input_id').attr('placeholder','New Text Here');

Can also clear the placeholder if required like:

$('#some_input_id').attr('placeholder','');

When we use CommandObj.Parameter.Add() it takes 2 parameters, the first is procedure parameter and the second is its data type, while .AddWithValue() takes 2 parameters, the first is procedure parameter and the second is the data variable

CommandObj.Parameter.Add("@ID",SqlDbType.Int).Value=textBox1.Text;

for .AddWithValue

CommandObj.Parameter.AddWitheValue("@ID",textBox1.Text);

where ID is the parameter of stored procedure which data type is Int

You can pass an InputStream to the Property, so your file can pretty much be anywhere, and called anything.

Properties properties = new Properties();
try {
  properties.load(new FileInputStream("path/filename"));
} catch (IOException e) {
  ...
}

Iterate as:

for(String key : properties.stringPropertyNames()) {
  String value = properties.getProperty(key);
  System.out.println(key + " => " + value);
}

You should stick to the NSInteger data types when possible. So you'd create the number like that:

NSInteger myValue = 1;
NSNumber *number = [NSNumber numberWithInteger: myValue];

Decoding works with the integerValue method then:

NSInteger value = [number integerValue];

The usual command line ping tool uses ICMP Echo, but it's true that other protocols can also be used, and they're useful in debugging different kinds of network problems.

I can remember at least arping (for testing ARP requests) and tcping (which tries to establish a TCP connection and immediately closes it, it can be used to check if traffic reaches a certain port on a host) off the top of my head, but I'm sure there are others aswell.

As replacing "\n" with "" doesn't give you the result that you want, that means that what you should replace is actually not "\n", but some other character combination.

One possibility is that what you should replace is the "\r\n" character combination, which is the newline code in a Windows system. If you replace only the "\n" (line feed) character it will leave the "\r" (carriage return) character, which still may be interpreted as a line break, depending on how you display the string.

If the source of the string is system specific you should use that specific string, otherwise you should use Environment.NewLine to get the newline character combination for the current system.

string temp = mystring.Replace("\r\n", string.Empty);

or:

string temp = mystring.Replace(Environment.NewLine, string.Empty);

It's called a middle dot: ·

In short:

• OpenJDK has multiple meanings and can refer to:
  • free and open source implementation of the Java Platform, Standard Edition (Java SE)
  • open source repository — the Java source code aka OpenJDK project
  • prebuilt OpenJDK binaries maintained by Oracle
  • prebuilt OpenJDK binaries maintained by the OpenJDK community
• AdoptOpenJDK — prebuilt OpenJDK binaries maintained by community (open source licensed)

Explanation:

Prebuilt OpenJDK (or distribution) — binaries, built from http://hg.openjdk.java.net/, provided as an archive or installer, offered for various platforms, with a possible support contract.

OpenJDK, the source repository (also called OpenJDK project) - is a Mercurial-based open source repository, hosted at http://hg.openjdk.java.net. The Java source code. The vast majority of Java features (from the VM and the core libraries to the compiler) are based solely on this source repository. Oracle have an alternate fork of this.

OpenJDK, the distribution (see the list of providers below) - is free as in beer and kind of free as in speech, but, you do not get to call Oracle if you have problems with it. There is no support contract. Furthermore, Oracle will only release updates to any OpenJDK (the distribution) version if that release is the most recent Java release, including LTS (long-term support) releases. The day Oracle releases OpenJDK (the distribution) version 12.0, even if there's a security issue with OpenJDK (the distribution) version 11.0, Oracle will not release an update for 11.0. Maintained solely by Oracle.

Some OpenJDK projects - such as OpenJDK 8 and OpenJDK 11 - are maintained by the OpenJDK community and provide releases for some OpenJDK versions for some platforms. The community members have taken responsibility for releasing fixes for security vulnerabilities in these OpenJDK versions.

AdoptOpenJDK, the distribution is very similar to Oracle's OpenJDK distribution (in that it is free, and it is a build produced by compiling the sources from the OpenJDK source repository). AdoptOpenJDK as an entity will not be backporting patches, i.e. there won't be an AdoptOpenJDK 'fork/version' that is materially different from upstream (except for some build script patches for things like Win32 support). Meaning, if members of the community (Oracle or others, but not AdoptOpenJDK as an entity) backport security fixes to updates of OpenJDK LTS versions, then AdoptOpenJDK will provide builds for those. Maintained by OpenJDK community.

OracleJDK - is yet another distribution. Starting with JDK12 there will be no free version of OracleJDK. Oracle's JDK distribution offering is intended for commercial support. You pay for this, but then you get to rely on Oracle for support. Unlike Oracle's OpenJDK offering, OracleJDK comes with longer support for LTS versions. As a developer you can get a free license for personal/development use only of this particular JDK, but that's mostly a red herring, as 'just the binary' is basically the same as the OpenJDK binary. I guess it means you can download security-patched versions of LTS JDKs from Oracle's websites as long as you promise not to use them commercially.

Note. It may be best to call the OpenJDK builds by Oracle the "Oracle OpenJDK builds".

Donald Smith, Java product manager at Oracle writes:

Ideally, we would simply refer to all Oracle JDK builds as the "Oracle JDK", either under the GPL or the commercial license, depending on your situation. However, for historical reasons, while the small remaining differences exist, we will refer to them separately as Oracle’s OpenJDK builds and the Oracle JDK.

_{Free Builds from Source - the distribution source code is publicly available and one can assemble its own build}

_{Free Binary Distributions - the distribution binaries are publicly available for download and usage}

_{Extended Updates - aka LTS (long-term support) - Public Updates beyond the 6-month release lifecycle}

_{Commercial Support - some providers offer extended updates and customer support to paying customers, e.g. Oracle JDK (support details)}

_{Permissive License - the distribution license is non-protective, e.g. Apache 2.0}

Which Java Distribution Should I Use?

In the Sun/Oracle days, it was usually Sun/Oracle producing the proprietary downstream JDK distributions based on OpenJDK sources. Recently, Oracle had decided to do their own proprietary builds only with the commercial support attached. They graciously publish the OpenJDK builds as well on their https://jdk.java.net/ site.

What is happening starting JDK 11 is the shift from single-vendor (Oracle) mindset to the mindset where you select a provider that gives you a distribution for the product, under the conditions you like: platforms they build for, frequency and promptness of releases, how support is structured, etc. If you don't trust any of existing vendors, you can even build OpenJDK yourself.

Each build of OpenJDK is usually made from the same original upstream source repository (OpenJDK “the project”). However each build is quite unique - $free or commercial, branded or unbranded, pure or bundled (e.g., BellSoft Liberica JDK offers bundled JavaFX, which was removed from Oracle builds starting JDK 11).

If no environment (e.g., Linux) and/or license requirement defines specific distribution and if you want the most standard JDK build, then probably the best option is to use OpenJDK by Oracle or AdoptOpenJDK.

For 32 bit OS you must add a registry entry to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

*******OR*******

For 64 bit OS you must add a registry entry to:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

This entry must be a DWORD, with the name being the name of your executable, that hosts the Webbrowser control; i.e.:

myappname.exe (DON'T USE "Contoso.exe" as in the MSDN web page...it's just a placeholder name)

Then give it a DWORD value, according to the table on:

http://msdn.microsoft.com/en-us/library/ee330730(v=vs.85).aspx#browser_emulation

I changed to 11001 decimal or 0x2AF9 hex --- (IE 11 EMULATION) since that isn't the DEFAULT value (if you have IE 11 installed -- or whatever version).

That MSDN article contains notes on several other Registry changes that affects Internet Explorer web browser behavior.

If you don't mind including the underscore as an allowed character, you could try simply:

result = subject.replace(/\W+/g, "");

If the underscore must be excluded also, then

result = subject.replace(/[^A-Z0-9]+/ig, "");

(Note the case insensitive flag)

The brief difference in layman's term is:

• If you are working on an interface or module that provides support to other modules by exposing the members of the stated dependency you should be using 'api'.
• If you are making an application or module that is going to implement or use the stated dependency internally, use 'implementation'.
• 'compile' worked same as 'api', however, if you are only implementing or using any library, 'implementation' will work better and save you resources.

read the answer by @aldok for a comprehensive example.

This might be helpful for whoever else faces this problem. I finally figured out a solution. Turns out, even if we use the inline for "content-disposition" and specify a file name, the browsers still do not use the file name. Instead browsers try and interpret the file name based on the Path/URL.

You can read further on this URL: Securly download file inside browser with correct filename

This gave me an idea, I just created my URL route that would convert the URL and end it with the name of the file I wanted to give the file. So for e.g. my original controller call just consisted of passing the Order Id of the Order being printed. I was expecting the file name to be of the format Order{0}.pdf where {0} is the Order Id. Similarly for quotes, I wanted Quote{0}.pdf.

In my controller, I just went ahead and added an additional parameter to accept the file name. I passed the filename as a parameter in the URL.Action method.

I then created a new route that would map that URL to the format: http://localhost/ShoppingCart/PrintQuote/1054/Quote1054.pdf

routes.MapRoute("", "{controller}/{action}/{orderId}/{fileName}",
                new { controller = "ShoppingCart", action = "PrintQuote" }
                , new string[] { "x.x.x.Controllers" }
            );

This pretty much solved my issue. Hoping this helps someone!

Also, instead of inner classes, you can use your 2 or more classes as fields.

For example:

Class Man{
private Phone ownPhone;
private DeviceInfo info;
//sets; gets
}
Class Phone{
private String phoneType;
private Long phoneNumber;
//sets; gets
}

Class DeviceInfo{

String phoneModel;
String cellPhoneOs;
String osVersion;
String phoneRam;
//sets; gets

}

So, here you have a man who can have some Phone with its number and type, also you have DeviceInfo for that Phone.

Also, it's possible is better to use DeviceInfo as a field into Phone class, like

class Phone {
DeviceInfo info;
String phoneNumber;
Stryng phoneType;
//sets; gets
}

Add xmlns context with http as shown below

xmlns:context="http://www.springframework.org/schema/context"

The maximum SqlDbType.VarChar size is 2147483647.

If you would use a generic oledb connection instead of sql, I found here there is also a LongVarChar datatype. Its max size is 2147483647.

cmd.Parameters.Add("@blah", OleDbType.LongVarChar, -1).Value = "very big string";

I don't know the best way, but the easiest way if you want to define a global variable inside of a component is to use window variable to write like this:

window.GlobalVariable = "what ever!"

you don't need to pass it to bootstrap or import it other places, and it is globally accessibly to all JS (not only angular 2 components).

copy *.txt all.txt

This will concatenate all text files of the folder to one text file all.txt

If you have any other type of files, like sql files

copy *.sql all.sql

A simple solution but it gets the job done, assigns a known length and precision and avoids the chance of going exponential format (which is a risk when you use %g):

// Since we are only interested in 3 decimal places, this function
// can avoid any potential miniscule floating point differences
// which can return false when using "=="
int DoubleEquals(double i, double j)
{
    return (fabs(i - j) < 0.000001);
}

void PrintMaxThreeDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%.1f", d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%.2f", d);
    else
        printf("%.3f", d);
}

Add or remove "elses" if you want a max of 2 decimals; 4 decimals; etc.

For example if you wanted 2 decimals:

void PrintMaxTwoDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%.1f", d);
    else
        printf("%.2f", d);
}

If you want to specify the minimum width to keep fields aligned, increment as necessary, for example:

void PrintAlignedMaxThreeDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%7.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%9.1f", d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%10.2f", d);
    else
        printf("%11.3f", d);
}

You could also convert that to a function where you pass the desired width of the field:

void PrintAlignedWidthMaxThreeDecimal(int w, double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%*.0f", w-4, d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%*.1f", w-2, d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%*.2f", w-1, d);
    else
        printf("%*.3f", w, d);
}

Error-Handling with SQL Stored Procedures

TRY/CATCH error handling can take place either within or outside of a procedure (or both). The examples below demonstrate error handling in both cases.

If you want to experiment further, you can fork the query on Stack Exchange Data Explorer.

_{(This uses a temporary stored procedure... we can't create regular SP's on SEDE, but the functionality is the same.)}

--our Stored Procedure
create procedure #myProc as --we can only create #temporary stored procedures on SEDE. 
  begin
    BEGIN TRY
      print 'This is our Stored Procedure.'
      print 1/0                          --<-- generate a "Divide By Zero" error.
      print 'We are not going to make it to this line.'
    END TRY

    BEGIN CATCH
      print 'This is the CATCH block within our Stored Procedure:'
          + ' Error Line #'+convert(varchar,ERROR_LINE())
          + ' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
      --print 1/0                        --<-- generate another "Divide By Zero" error.
        -- uncomment the line above to cause error within the CATCH ¹ 
    END CATCH
  end
go

--our MAIN code block:
BEGIN TRY
  print 'This is our MAIN Procedure.'
  execute #myProc  --execute the Stored Procedure
      --print 1/0                        --<-- generate another "Divide By Zero" error.
        -- uncomment the line above to cause error within the MAIN Procedure ²
  print 'Now our MAIN sql code block continues.'
END TRY

BEGIN CATCH
  print 'This is the CATCH block for our MAIN sql code block:'
          + ' Error Line #'+convert(varchar,ERROR_LINE())
          + ' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
END CATCH

Here's the result of running the above sql as-is:

This is our MAIN Procedure.
This is our Stored Procedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
Now our MAIN sql code block continues.

¹ Uncommenting the "additional error line" from the Stored Procedure's CATCH block will produce:

This is our MAIN procedure.
This is our Stored Procedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
This is the CATCH block for our MAIN sql code block: Error Line #13 of procedure #myProc

² Uncommenting the "additional error line" from the MAIN procedure will produce:

This is our MAIN Procedure.
This is our Stored Pprocedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
This is the CATCH block for our MAIN sql code block: Error Line #4 of procedure (Main)

Use a single procedure for error handling

On topic of stored procedures and error handling, it can be helpful (and tidier) to use a single, dynamic, stored procedure to handle errors for multiple other procedures or code sections.

Here's an example:

--our error handling procedure
create procedure #myErrorHandling as
  begin
    print ' Error #'+convert(varchar,ERROR_NUMBER())+': '+ERROR_MESSAGE()  
    print ' occurred on line #'+convert(varchar,ERROR_LINE())
         +' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
    if ERROR_PROCEDURE() is null       --check if error was in MAIN Procedure
      print '*Execution cannot continue after an error in the MAIN Procedure.'
  end
go

create procedure #myProc as     --our test Stored Procedure
  begin
    BEGIN TRY
      print 'This is our Stored Procedure.'
      print 1/0                       --generate a "Divide By Zero" error.
      print 'We will not make it to this line.'
    END TRY
    BEGIN CATCH
     execute #myErrorHandling
    END CATCH

Documentation:

In the scope of a TRY/CATCH block, the following system functions can be used to obtain information about the error that caused the CATCH block to be executed:

• ERROR_NUMBER() returns the number of the error.
• ERROR_SEVERITY() returns the severity.
• ERROR_STATE() returns the error state number.
• ERROR_PROCEDURE() returns the name of the stored procedure or trigger where the error occurred.
• ERROR_LINE() returns the line number inside the routine that caused the error.
• ERROR_MESSAGE() returns the complete text of the error message. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times.

Note that there are two types of SQL errors: Terminal and Catchable. TRY/CATCH will [obviously] only catch the "Catchable" errors. This is one of a number of ways of learning more about your SQL errors, but it probably the most useful.

It's "better to fail now" (during development) compared to later because, as Homer says . . .

Using case

#!/bin/bash

fun1 () {
    echo "run function1"
    [[ "$@" ]] && echo "options: $@"
}

fun2 () {
    echo "run function2"
    [[ "$@" ]] && echo "options: $@"
}

case $1 in
    fun1) "$@"; exit;;
    fun2) "$@"; exit;;
esac

fun1
fun2

This script will run functions fun1 and fun2 but if you start it with option fun1 or fun2 it'll only run given function with args(if provided) and exit. Usage

$ ./test 
run function1
run function2

$ ./test fun2 a b c
run function2
options: a b c

If you know in advance where the loop will have to stop, it will probably improve code readability to state the condition in the for, while, or `do-while loop.

Otherwise, that's the exact use case for break.

Your question was already answered by the other posters, I'd just like to point out that

 delete from table where id <> 2

(or variants thereof, not id = 2 etc) will not delete rows where id is NULL.

If you also want to delete rows with id = NULL:

delete from table where id <> 2 or id is NULL

This will work too

my_country_code="green"
x="country"

eval z='$'my_"$x"_code
echo $z                 ## o/p: green

In your case

eval final_val='$'magic_way_to_define_magic_variable_"$1"
echo $final_val

select date_format(str_to_date('31/12/2010', '%d/%m/%Y'), '%Y%m'); 

or

select date_format(str_to_date('12/31/2011', '%m/%d/%Y'), '%Y%m'); 

hard to tell from your example

Here's a polyfill for the Number predicate functions:

"use strict";

Number.isNaN = Number.isNaN ||
    n => n !== n; // only NaN

Number.isNumeric = Number.isNumeric ||
    n => n === +n; // all numbers excluding NaN

Number.isFinite = Number.isFinite ||
    n => n === +n               // all numbers excluding NaN
      && n >= Number.MIN_VALUE  // and -Infinity
      && n <= Number.MAX_VALUE; // and +Infinity

Number.isInteger = Number.isInteger ||
    n => n === +n              // all numbers excluding NaN
      && n >= Number.MIN_VALUE // and -Infinity
      && n <= Number.MAX_VALUE // and +Infinity
      && !(n % 1);             // and non-whole numbers

Number.isSafeInteger = Number.isSafeInteger ||
    n => n === +n                     // all numbers excluding NaN
      && n >= Number.MIN_SAFE_INTEGER // and small unsafe numbers
      && n <= Number.MAX_SAFE_INTEGER // and big unsafe numbers
      && !(n % 1);                    // and non-whole numbers

All major browsers support these functions, except isNumeric, which is not in the specification because I made it up. Hence, you can reduce the size of this polyfill:

"use strict";

Number.isNumeric = Number.isNumeric ||
    n => n === +n; // all numbers excluding NaN

Alternatively, just inline the expression n === +n manually.

Check this post under FileUpload Control

Additionally, the “Include local directory path when uploading files” URLAction has been set to "Disable" for the Internet Zone. This change prevents leakage of potentially sensitive local file-system information to the Internet. For instance, rather than submitting the full path C:\users\ericlaw\documents\secret\image.png, Internet Explorer 8 will now submit only the filename image.png.

Its an option under Internet security that can be enabled

Might want to try

keytool -import -trustcacerts -noprompt -keystore <full path to cacerts> -storepass changeit -alias $REMHOST -file $REMHOST.pem

i honestly have no idea where it puts your certificate if you just write cacerts just give it a full path

Check out Apache Commons FileUtils (listFiles, iterateFiles, etc.). Nice convenience methods for doing what you want and also applying filters.

http://commons.apache.org/io/api-1.4/org/apache/commons/io/FileUtils.html

In my case a background Java Virtual Machine instance was running, killing which cleanup was successful.

If you are using SQL Server 2012 and above, you can use FORMATMESSAGE. eg.

DECLARE @s NVARCHAR(50) = 'World';
DECLARE @d INT = 123;
SELECT FORMATMESSAGE('Hello %s, %d', @s, @d)
-- RETURNS 'Hello World, 123'

More examples from MSDN: FORMATMESSAGE

SELECT FORMATMESSAGE('Signed int %i, %d %i, %d, %+i, %+d, %+i, %+d', 5, -5, 50, -50, -11, -11, 11, 11);
SELECT FORMATMESSAGE('Signed int with leading zero %020i', 5);
SELECT FORMATMESSAGE('Signed int with leading zero 0 %020i', -55);
SELECT FORMATMESSAGE('Unsigned int %u, %u', 50, -50);
SELECT FORMATMESSAGE('Unsigned octal %o, %o', 50, -50);
SELECT FORMATMESSAGE('Unsigned hexadecimal %x, %X, %X, %X, %x', 11, 11, -11, 50, -50);
SELECT FORMATMESSAGE('Unsigned octal with prefix: %#o, %#o', 50, -50);
SELECT FORMATMESSAGE('Unsigned hexadecimal with prefix: %#x, %#X, %#X, %X, %x', 11, 11, -11, 50, -50);
SELECT FORMATMESSAGE('Hello %s!', 'TEST');
SELECT FORMATMESSAGE('Hello %20s!', 'TEST');
SELECT FORMATMESSAGE('Hello %-20s!', 'TEST');
SELECT FORMATMESSAGE('Hello %20s!', 'TEST');

NOTES:

• Undocumented in 2012
• Limited to 2044 characters
• To escape the % sign, you need to double it.
• If you are logging errors in extended events, calling FORMATMESSAGE comes up as a (harmless) error

Exclamation mark makes any function always return a boolean.
The final value is the negation of the value returned by the function.

!function bool() { return false; }() // true
!function bool() { return true; }() // false

Omitting ! in the above examples would be a SyntaxError.

function bool() { return true; }() // SyntaxError

However, a better way to achieve this would be:

(function bool() { return true; })() // true

You need to convert the string to date using the to_date() function

SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31-Dec-2014','DD-MON-YYYY');

OR

SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014','DD MON YYYY');

OR

SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('2014-12-31','yyyy-MM-dd');

This will work only if OrderDate is stored in Date format. If it is Varchar you should apply to_date() func on that column also like

 SELECT * FROM OrderArchive
    WHERE to_date(OrderDate,'yyyy-Mm-dd') <= to_date('2014-12-31','yyyy-MM-dd');

I think introduction to Algorithms is the reference books, and a must have for any serious programmer.

Other fun book is The algorithm design manual http://www.algorist.com/. It covers more sophisticated algorithms.

I can't not mention The art of computer programming of Knuth http://www-cs-faculty.stanford.edu/~knuth/taocp.html

Make sure "Use: Regular expressions" is selected in the Find and Replace dialog:

Note that for Visual Studio 2010, this doesn't work in the Visual Studio Productivity Power Tools' "Quick Find" extension (as of the July 2011 update); instead, you'll need to use the full Find and Replace dialog (use Ctrl+Shift+H, or Edit --> Find and Replace --> Replace in Files), and change the scope to "Current Document".

Changing my header to the following solve the problem:

You don't have JSON. You have a JavaScript data structure consisting of objects, an array, some strings and some numbers.

Use JSON.stringify(object) to turn it into (a string of) JSON text.

Using data.frame instead of cbind should be helpful

x <- data.frame(col1=c(10, 20), col2=c("[]", "[]"), col3=c("[[1,2]]","[[1,3]]"))
x
  col1 col2    col3
1   10   [] [[1,2]]
2   20   [] [[1,3]]

sapply(x, class) # looking into x to see the class of each element
     col1      col2      col3 
"numeric"  "factor"  "factor" 

As you can see elements from col1 are numeric as you wish.

data.frame can have variables of different class: numeric, factor and character but matrix doesn't, once you put a character element into a matrix all the other will become into this class no matter what clase they were before.

Even though this is much later than the request, it might help others. Docmosis provides a Java API for creating documents in doc,pdf,odt format using documents as templates. It uses OpenOffice as the engine to perform the format conversions. Document manipulation and population is performed by Docmosis itself.

Note: You can play back the audio data only to the standard output device.
Currently, that is the mobile device speaker or a Bluetooth headset. You

The following is applicable for docker-compose 3.x Set environment variables inside the container

method - 1 Straight method

web:
  environment:
    - DEBUG=1
      POSTGRES_PASSWORD: 'postgres'
      POSTGRES_USER: 'postgres'

method - 2 The “.env” file

Create a .env file in the same location as the docker-compose.yml

$ cat .env
TAG=v1.5
POSTGRES_PASSWORD: 'postgres'

and your compose file will be like

$ cat docker-compose.yml
version: '3'
services:
  web:
    image: "webapp:${TAG}"
    postgres_password: "${POSTGRES_PASSWORD}"

I think it's important to add a thing, if you use the layout inflation that constructor in the drawview is not correct, add these constructors in the class:

public DrawingView(Context c, AttributeSet attrs) {
    super(c, attrs);
    ...
}

public DrawingView(Context c, AttributeSet attrs, int defStyle) {
    super(c, attrs, defStyle);
    ...
}

or the android system fails to inflate the layout file. I hope this could to help.

I was looking for the TOTAL size of the column and hit this article, my solution is based off of MarcE's.

SELECT sum(DATALENGTH(your_field)) AS FIELDSIZE FROM your_table

Create and save a java.awt.image.bufferedImage to file:

import java.io.*;
import java.awt.image.*;
import javax.imageio.*;
public class Main{
    public static void main(String args[]){
        try{
            BufferedImage img = new BufferedImage( 
                500, 500, BufferedImage.TYPE_INT_RGB );

            File f = new File("MyFile.png");
            int r = 5;
            int g = 25;
            int b = 255;
            int col = (r << 16) | (g << 8) | b;
            for(int x = 0; x < 500; x++){
                for(int y = 20; y < 300; y++){
                    img.setRGB(x, y, col);
                }
            }
            ImageIO.write(img, "PNG", f);
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}

Notes:

1. Creates a file called MyFile.png.
2. Image is 500 by 500 pixels.
3. Overwrites the existing file.
4. The color of the image is black with a blue stripe across the top.

I have to assume you meant to say that you wanted a mean of 0 and a standard deviation of 1. If your data is in a dataframe and all the columns are numeric you can simply call the scale function on the data to do what you want.

dat <- data.frame(x = rnorm(10, 30, .2), y = runif(10, 3, 5))
scaled.dat <- scale(dat)

# check that we get mean of 0 and sd of 1
colMeans(scaled.dat)  # faster version of apply(scaled.dat, 2, mean)
apply(scaled.dat, 2, sd)

Using built in functions is classy. Like this cat:

Select both the column you are sorting, and the column that the picture is in (I am assuming the picture is small compared to the cell, i.e. it is "in" the cell). Make sure that the object positioning property is set as "move but don't size with cells". Now if you do a sort, the pictures will move with the list being sorted.

Note - you must include the column with the picture in your range when you sort, and the picture must fit inside the cell.

The following VBA snippet will make sure all pictures in your spreadsheet have their "move and size" property set:

Sub moveAndSize()
Dim s As Shape
For Each s In ActiveSheet.Shapes
  If s.Type = msoPicture Or s.Type = msoLinkedPicture Or s.Type = msoPlaceholder Then
    s.Placement = xlMove
  End If
Next
End Sub

If you want to make sure the picture continues to fit after you move it, you can use xlMoveAndSize instead of xlMove.

Depending on the AWK implementation are you using == is ok or not.

Have you tried ~?. For example, if you want $1 to be "hello":

awk '$1 ~ /^hello$/{ print $3; }' <infile>

^ means $1 start, and $ is $1 end.

Spring abstracts you from the very very very large list of http status code. That is the idea of the exceptions. Take a look into org.springframework.web.client.RestClientException hierarchy:

You have a bunch of classes to map the most common situations when dealing with http responses. The http codes list is really large, you won't want write code to handle each situation. But for example, take a look into the HttpClientErrorException sub-hierarchy. You have a single exception to map any 4xx kind of error. If you need to go deep, then you can. But with just catching HttpClientErrorException, you can handle any situation where bad data was provided to the service.

The DefaultResponseErrorHandler is really simple and solid. If the response status code is not from the family of 2xx, it just returns true for the hasError method.

Because GFW forbidden you to access golang.org ! And when i use the proxy , it can work well.

you can look at the information using command go get -v -u golang.org/x/oauth2

When the UI component that registers the BR is destroyed, so is the BR. Therefore when the code gets to unregistering, the BR may have already been destroyed.

An approach using the standard URL:

/**
 * @param {string} path - A path starting with "/"
 * @return {string}
 */
function getPathname(path) {
  return new URL(`http://_${path}`).pathname
}

getPathname('/foo/bar?cat=5') // /foo/bar

I'm using Node worker to run processes in a simple way from my main process. Seems to be working great while we wait for the official way to come around.

Here's an alternative approach using an interface to describe the shape of an options object to be passed via the pipe in the markup.

@Pipe({
  name: 'textContentTruncate'
})
export class TextContentTruncatePipe implements PipeTransform {

  transform(textContent: string, options: TextTruncateOptions): string {
    if (textContent.length >= options.sliceEnd) {
      let truncatedText = textContent.slice(options.sliceStart, options.sliceEnd);
      if (options.prepend) { truncatedText = `${options.prepend}${truncatedText}`; }
      if (options.append) { truncatedText = `${truncatedText}${options.append}`; }
      return truncatedText;
    }
    return textContent;
  }

}

interface TextTruncateOptions {
  sliceStart: number;
  sliceEnd: number;
  prepend?: string;
  append?: string;
}

Then in your markup:

{{someText | textContentTruncate:{sliceStart: 0, sliceEnd: 50, append: '...'} }}

Assuming we are using Jupyter Notebook (if using Terminal, drop the exclamation marks):

1) if the package (e.g. xgboost) was installed with pip:

!pip show xgboost
!pip freeze | grep xgboost
!pip list | grep xgboost

2) if the package (e.g. caffe) was installed with conda:

!conda list caffe

First check out config files for syntax errors with apachectl configtest and then look into apache error logs.

<input type="text" id="input_id" />    

$('#input_id').keydown(function (event) {
    if (event.keyCode == 13) { 
         // Call your function here or add code here
    }
});

The abort function does this. For example:

abort("Message goes here")

Note: the abort message will be written to STDERR as opposed to puts which will write to STDOUT.

Couple of points:

• I believe git stash + git stash drop could be replaced with git reset --hard

• ... or, even shorter, add -f to checkout command:

  git checkout -f -b $branch
  

  That will discard any local changes, just as if git reset --hard was used prior to checkout.

As for the main question: instead of pulling in the last step, you could just merge the appropriate branch from the remote into your local branch: git merge $branch origin/$branch, I believe it does not hit the remote. If that is the case, it removes the need for credensials and hence, addresses your biggest concern.

I want to stress on using

SET XACT_ABORT ON;

for the MSSQL transaction with multiple sql statements.

See: https://msdn.microsoft.com/en-us/library/ms188792.aspx They provide a very good example.

So, the final code should look like the following:

SET XACT_ABORT ON;

BEGIN TRANSACTION
   DECLARE @DataID int;
   INSERT INTO DataTable (Column1 ...) VALUES (....);
   SELECT @DataID = scope_identity();
   INSERT INTO LinkTable VALUES (@ObjectID, @DataID);
