One liner for Python based on scai's answer, but a) takes stdin, b) makes the result repeatable with seed, c) picks out only 200 of all lines.

Here is a working and efficient Fisher–Yates shuffle array function:

private static void shuffleArray(int[] array)
{
    int index;
    Random random = new Random();
    for (int i = array.length - 1; i > 0; i--)
    {
        index = random.nextInt(i + 1);
        if (index != i)
        {
            array[index] ^= array[i];
            array[i] ^= array[index];
            array[index] ^= array[i];
        }
    }
}

or

private static void shuffleArray(int[] array)
{
    int index, temp;
    Random random = new Random();
    for (int i = array.length - 1; i > 0; i--)
    {
        index = random.nextInt(i + 1);
        temp = array[index];
        array[index] = array[i];
        array[i] = temp;
    }
}

With an example, this is what I'm doing:

combo = []
for i in range(60000):
    combo.append((images[i], labels[i]))

shuffle(combo)

im = []
lab = []
for c in combo:
    im.append(c[0])
    lab.append(c[1])
images = np.asarray(im)
labels = np.asarray(lab)

//one line solution
shuffle = (array) => array.sort(() => Math.random() - 0.5);


//Demo
let arr = [1, 2, 3];
shuffle(arr);
alert(arr);

https://javascript.info/task/shuffle

Math.random() - 0.5 is a random number that may be positive or negative, so the sorting function reorders elements randomly.

from random import random
my_list = range(10)
shuffled_list = sorted(my_list, key=lambda x: random())

This alternative may be useful for some applications where you want to swap the ordering function.

shuffle the pandas data frame by taking a sample array in this case index and randomize its order then set the array as an index of data frame. Now sort the data frame according to index. Here goes your shuffled dataframe

import random
df = pd.DataFrame({"a":[1,2,3,4],"b":[5,6,7,8]})
index = [i for i in range(df.shape[0])]
random.shuffle(index)
df.set_index([index]).sort_index()

output

    a   b
0   2   6
1   1   5
2   3   7
3   4   8

Insert you data frame in the place of mine in above code .

I've always assumed this was necessary as the output from the mapper is the input for the reducer, so it was sorted based on the keyspace and then split into buckets for each reducer input. You want to ensure all the same values of a Key end up in the same bucket going to the reducer so they are reduced together. There is no point sending K1,V2 and K1,V4 to different reducers as they need to be together in order to be reduced.

Tried explaining it as simply as possible

Alternative way to do this using sklearn

from sklearn.utils import shuffle
X=[1,2,3]
y = ['one', 'two', 'three']
X, y = shuffle(X, y, random_state=0)
print(X)
print(y)

Output:

[2, 1, 3]
['two', 'one', 'three']

Advantage: You can random multiple arrays simultaneously without disrupting the mapping. And 'random_state' can control the shuffling for reproducible behavior.

I decided that most popular symbols recommended here (? and ?) are looking too bold, so on the site codepoints.net, recommended by user ADJenks, I found these symbols which are looking better for my taste: (U+1F780) (U+1F781) (U+1F782) (U+1F783)

The easiest is probably to create a PKCS#12 file using OpenSSL:

openssl pkcs12 -export -in abc.crt -inkey abc.key -out abc.p12

You should be able to use the resulting file directly using the PKCS12 keystore type.

If you really need to, you can convert it to JKS using keytool -importkeystore (available in keytool from Java 6):

keytool -importkeystore -srckeystore abc.p12 \
        -srcstoretype PKCS12 \
        -destkeystore abc.jks \
        -deststoretype JKS

For example if I had an application source code structure that looked like this:

• C:\b2b\com\steve\util\
• C:\b2b\com\steve\app\
• C:\b2b\com\steve\gui\

Then I would do:

javadoc -d "C:\docs" -sourcepath "C:\b2b" -subpackages com

And that should create javadocs for source code of the com package, and all subpackages (recursively), found inside the "C:\b2b" directory.

window.scrollBarWidth = function() {
  document.body.style.overflow = 'hidden'; 
  var width = document.body.clientWidth;
  document.body.style.overflow = 'scroll'; 
  width -= document.body.clientWidth; 
  if(!width) width = document.body.offsetWidth - document.body.clientWidth;
  document.body.style.overflow = ''; 
  return width; 
} 

According to the RFC that introduced the operator, $a <=> $b evaluates to:

• 0 if $a == $b
• -1 if $a < $b
• 1 if $a > $b

which seems to be the case in practice in every scenario I've tried, although strictly the official docs only offer the slightly weaker guarantee that $a <=> $b will return

an integer less than, equal to, or greater than zero when $a is respectively less than, equal to, or greater than $b

Regardless, why would you want such an operator? Again, the RFC addresses this - it's pretty much entirely to make it more convenient to write comparison functions for usort (and the similar uasort and uksort).

usort takes an array to sort as its first argument, and a user-defined comparison function as its second argument. It uses that comparison function to determine which of a pair of elements from the array is greater. The comparison function needs to return:

an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

The spaceship operator makes this succinct and convenient:

$things = [
    [
        'foo' => 5.5,
        'bar' => 'abc'
    ],
    [
        'foo' => 7.7,
        'bar' => 'xyz'
    ],
    [
        'foo' => 2.2,
        'bar' => 'efg'
    ]
];

// Sort $things by 'foo' property, ascending
usort($things, function ($a, $b) {
    return $a['foo'] <=> $b['foo'];
});

// Sort $things by 'bar' property, descending
usort($things, function ($a, $b) {
    return $b['bar'] <=> $a['bar'];
});

More examples of comparison functions written using the spaceship operator can be found in the Usefulness section of the RFC.

There is no right way, but you can initialize an array of literals:

char **values = (char *[]){"a", "b", "c"};

or you can allocate each and initialize it:

char **values = malloc(sizeof(char*) * s);
for(...)
{
    values[i] = malloc(sizeof(char) * l);
    //or
    values[i] = "hello";
}

There is also deltree if you're on an older version of windows.

You can learn more about it from here: SS64: DELTREE - Delete all subfolders and files.

The keypress event from jQuery is meant to do this sort of work. You can trigger the event by passing a string "keypress" to .trigger(). However to be more specific you can actually pass a jQuery.Event object (specify the type as "keypress") as well and provide any properties you want such as the keycode being the spacebar.

http://docs.jquery.com/Events/trigger#eventdata

Read the above documentation for more details.

update 2 ::slotted

::slotted is now supported by all new browsers and can be used with ViewEncapsulation.ShadowDom

https://developer.mozilla.org/en-US/docs/Web/CSS/::slotted

update 1 ::ng-deep

/deep/ was deprecated and replaced by ::ng-deep.

::ng-deep is also already marked deprecated, but there is no replacement available yet.

When ViewEncapsulation.Native is properly supported by all browsers and supports styling accross shadow DOM boundaries, ::ng-deep will probably be discontinued.

original

Angular adds all kinds of CSS classes to the HTML it adds to the DOM to emulate shadow DOM CSS encapsulation to prevent styles of bleeding in and out of components. Angular also rewrites the CSS you add to match these added classes. For HTML added using [innerHTML] these classes are not added and the rewritten CSS doesn't match.

As a workaround try

• for CSS added to the component

/* :host /deep/ mySelector { */
:host ::ng-deep mySelector { 
  background-color: blue;
}

• for CSS added to index.html

/* body /deep/ mySelector { */
body ::ng-deep mySelector {
  background-color: green;
}

>>> (and the equivalent/deep/ but /deep/ works better with SASS) and ::shadow were added in 2.0.0-beta.10. They are similar to the shadow DOM CSS combinators (which are deprecated) and only work with encapsulation: ViewEncapsulation.Emulated which is the default in Angular2. They probably also work with ViewEncapsulation.None but are then only ignored because they are not necessary. These combinators are only an intermediate solution until more advanced features for cross-component styling is supported.

Another approach is to use

@Component({
  ...
  encapsulation: ViewEncapsulation.None,
})

for all components that block your CSS (depends on where you add the CSS and where the HTML is that you want to style - might be all components in your application)

Update

Example Plunker

You can also cheat in some way by hidding a submit button on your form and triggering it when you click on your modal button.

To do this via TSQL (ssms query window or sqlcmd.exe) just run:

RESTORE DATABASE MyDatabase FROM DISK='c:\backups\MyDataBase1.bak'

To do it via GUI - open SSMS, right click on Databases and follow the steps below

Unfortunately the performance of getScaledInstance() is very poor if not problematic.

The alternative approach is to create a new BufferedImage and and draw a scaled version of the original on the new one.

BufferedImage resized = new BufferedImage(newWidth, newHeight, original.getType());
Graphics2D g = resized.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
    RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.drawImage(original, 0, 0, newWidth, newHeight, 0, 0, original.getWidth(),
    original.getHeight(), null);
g.dispose();

newWidth,newHeight indicate the new BufferedImage size and have to be properly calculated. In case of factor scaling:

int newWidth = new Double(original.getWidth() * widthFactor).intValue();
int newHeight = new Double(original.getHeight() * heightFactor).intValue();

EDIT: Found the article illustrating the performance issue: The Perils of Image.getScaledInstance()

There is the JavaScriptSerializer class you can use too. That will let you deserialize the json to a .NET object. There's a generic Deserialize<T>, though you will need the .NET object to have a similar signature as the javascript one. Additionally there is also a DeserializeObject method that just makes a plain object. You can then use reflection to get at the properties you need.

If your controller takes a FormCollection, and you didn't add anything else to the data the json should be in form[0]:

public ActionResult Save(FormCollection forms) {
  string json = forms[0];
  // do your thing here.
}

Perhaps I am very late, but as of now there's another way to use it using the jquery ui slider.

To get a char from a Scanner, you can use the findInLine method.

    Scanner sc = new Scanner("abc");
    char ch = sc.findInLine(".").charAt(0);
    System.out.println(ch); // prints "a"
    System.out.println(sc.next()); // prints "bc"

If you need a bunch of char from a Scanner, then it may be more convenient to (perhaps temporarily) change the delimiter to the empty string. This will make next() returns a length-1 string every time.

    Scanner sc = new Scanner("abc");
    sc.useDelimiter("");
    while (sc.hasNext()) {
        System.out.println(sc.next());
    } // prints "a", "b", "c"

Try this, I think it will work for you:

<input type="file" webkitdirectory directory multiple/>

You can find the demo of this at https://plus.google.com/+AddyOsmani/posts/Dk5UhZ6zfF3 , and if you need further information you can find it here.

The basic syntax of initializing pointer that points to multidimentional array is

type (*pointer)[1st dimension size][2nd dimension size][..] = &array_name

The the basic syntax for calling it is

(*pointer_name)[1st index][2nd index][...]

Here is a example:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main() {
   // The multidimentional array...
   char balance[5][100] = {
       "Subham",
       "Messi"
   };

   char (*p)[5][100] = &balance; // Pointer initialization...

   printf("%s\n",(*p)[0]); // Calling...
   printf("%s\n",(*p)[1]); // Calling...

  return 0;
}

Output is:

Subham
Messi

It worked...

I encountered difficulties with Roi-Kyi Bryant's solution when multiple add-ins tried to modify the ribbon. I also don't have admin access on my work-computer, which ruled out installing the Custom UI Editor. So, if you're in the same boat as me, here's an alternative example to customising the ribbon using only Excel. Note, my solution is derived from the Microsoft guide.

1. Create Excel file/files whose ribbons you want to customise. In my case, I've created two .xlam files, Chart Tools.xlam and Priveleged UDFs.xlam, to demonstrate how multiple add-ins can interact with the Ribbon.
2. Create a folder, with any folder name, for each file you just created.
3. Inside each of the folders you've created, add a customUI and _rels folder.
4. Inside each customUI folder, create a customUI.xml file. The customUI.xml file details how Excel files interact with the ribbon. Part 2 of the Microsoft guide covers the elements in the customUI.xml file.

My customUI.xml file for Chart Tools.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:chartToolsTab" label="Chart Tools">
        <group id="relativeChartMovementGroup" label="Relative Chart Movement" >
            <button id="moveChartWithRelativeLinksButton" label="Copy and Move" imageMso="ResultsPaneStartFindAndReplace" onAction="MoveChartWithRelativeLinksCallBack" visible="true" size="normal"/>
            <button id="moveChartToManySheetsWithRelativeLinksButton" label="Copy and Distribute" imageMso="OutlineDemoteToBodyText" onAction="MoveChartToManySheetsWithRelativeLinksCallBack" visible="true" size="normal"/>
        </group >
        <group id="chartDeletionGroup" label="Chart Deletion">
            <button id="deleteAllChartsInWorkbookSharingAnAddressButton" label="Delete Charts" imageMso="CancelRequest" onAction="DeleteAllChartsInWorkbookSharingAnAddressCallBack" visible="true" size="normal"/>
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

My customUI.xml file for Priveleged UDFs.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:privelgedUDFsTab" label="Privelged UDFs">
        <group id="privelgedUDFsGroup" label="Toggle" >
            <button id="initialisePrivelegedUDFsButton" label="Activate" imageMso="TagMarkComplete" onAction="InitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
            <button id="deInitialisePrivelegedUDFsButton" label="De-Activate" imageMso="CancelRequest" onAction="DeInitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
        </group >
      </tab>
    </tabs>
  </ribbon>
</customUI>

5. For each file you created in Step 1, suffix a .zip to their file name. In my case, I renamed Chart Tools.xlam to Chart Tools.xlam.zip, and Privelged UDFs.xlam to Priveleged UDFs.xlam.zip.
6. Open each .zip file, and navigate to the _rels folder. Copy the .rels file to the _rels folder you created in Step 3. Edit each .rels file with a text editor. From the Microsoft guide

Between the final <Relationship> element and the closing <Relationships> element, add a line that creates a relationship between the document file and the customization file. Ensure that you specify the folder and file names correctly.

<Relationship Type="http://schemas.microsoft.com/office/2006/
  relationships/ui/extensibility" Target="/customUI/customUI.xml" 
  Id="customUIRelID" />

My .rels file for Chart Tools.xlam looks like this

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="chartToolsCustomUIRel" />
    </Relationships>

My .rels file for Priveleged UDFs looks like this.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="privelegedUDFsCustomUIRel" />
    </Relationships>

7. Replace the .rels files in each .zip file with the .rels file/files you modified in the previous step.
8. Copy and paste the .customUI folder you created into the home directory of the .zip file/files.
9. Remove the .zip file extension from the Excel files you created.
10. If you've created .xlam files, back in Excel, add them to your Excel add-ins.
11. If applicable, create callbacks in each of your add-ins. In Step 4, there are onAction keywords in my buttons. The onAction keyword indicates that, when the containing element is triggered, the Excel application will trigger the sub-routine encased in quotation marks directly after the onAction keyword. This is known as a callback. In my .xlam files, I have a module called CallBacks where I've included my callback sub-routines.

My CallBacks module for Chart Tools.xlam looks like

Option Explicit

Public Sub MoveChartWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartWithRelativeLinks
End Sub

Public Sub MoveChartToManySheetsWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartToManySheetsWithRelativeLinks
End Sub

Public Sub DeleteAllChartsInWorkbookSharingAnAddressCallBack(ByRef control As IRibbonControl)
  DeleteAllChartsInWorkbookSharingAnAddress
End Sub

My CallBacks module for Priveleged UDFs.xlam looks like

Option Explicit

Public Sub InitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.InitialisePrivelegedUDFs
End Sub

Public Sub DeInitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.DeInitialisePrivelegedUDFs
End Sub

Different elements have a different callback sub-routine signature. For buttons, the required sub-routine parameter is ByRef control As IRibbonControl. If you don't conform to the required callback signature, you will receive an error while compiling your VBA project/projects. Part 3 of the Microsoft guide defines all the callback signatures.

Here's what my finished example looks like

Some closing tips

1. If you want add-ins to share Ribbon elements, use the idQ and xlmns: keyword. In my example, the Chart Tools.xlam and Priveleged UDFs.xlam both have access to the elements with idQ's equal to x:chartToolsTab and x:privelgedUDFsTab. For this to work, the x: is required, and, I've defined its namespace in the first line of my customUI.xml file, <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.
2. If you want add-ins to access Ribbon elements shipped with Excel, use the isMSO keyword. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.

These are all interesting but what if you have a version number and you don't know the size of any one segment in string from and you want to drop the last segment. Something like 20.0.1.300 and I want to end up with 20.0.1 without the 300 on the end. I have this so far:

str('20.0.1.300'.split('.')[:3])

which returns in list form as:

['20', '0', '1']

How do I get it back to into a single string separated by periods

20.0.1

I know this is old, but I thought it might be helpful to show what these functions look like in code. This really illustrates the logic, better than text or a table IMO. In reality they are implemented in C rather than pure Python, but these are equivalent.

def any(iterable):
    for item in iterable:
        if item:
            return True
    return False

def all(iterable):
    for item in iterable:
        if not item:
            return False
    return True

In particular, you can see that the result for empty iterables is just the natural result, not a special case. You can also see the short-circuiting behaviour; it would actually be more work for there not to be short-circuiting.

When Guido van Rossum (the creator of Python) first proposed adding any() and all(), he explained them by just posting exactly the above snippets of code.

I believe you want to use CHARINDEX. You can read about it here.

All of the current answers are addressing the symptom (shared memory pool exhaustion), and not the problem, which is likely not using bind variables in your sql \ JDBC queries, even when it does not seem necessary to do so. Passing queries without bind variables causes Oracle to "hard parse" the query each time, determining its plan of execution, etc.

https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::p11_question_id:528893984337

Some snippets from the above link:

"Java supports bind variables, your developers must start using prepared statements and bind inputs into it. If you want your system to ultimately scale beyond say about 3 or 4 users -- you will do this right now (fix the code). It is not something to think about, it is something you MUST do. A side effect of this - your shared pool problems will pretty much disappear. That is the root cause. "

"The way the Oracle shared pool (a very important shared memory data structure) operates is predicated on developers using bind variables."

" Bind variables are SO MASSIVELY important -- I cannot in any way shape or form OVERSTATE their importance. "

Using a request scoped bean outside of an actual web request

I was having some trouble using an Indeterminate Progress Dialog with the solution here, after some work and trial and error I got it to work.

First, create the animation you want to use for the Progress Dialog. In my case I used 5 images.

../res/anim/progress_dialog_icon_drawable_animation.xml:

<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/icon_progress_dialog_drawable_1" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_2" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_3" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_4" android:duration="150" />
    <item android:drawable="@drawable/icon_progress_dialog_drawable_5" android:duration="150" />
</animation-list>

Where you want to show a ProgressDialog:

dialog = new ProgressDialog(Context.this);
dialog.setIndeterminate(true);
dialog.setIndeterminateDrawable(getResources().getDrawable(R.anim.progress_dialog_icon_drawable_animation));
dialog.setMessage("Some Text");
dialog.show();

This solution is really simple and worked for me, you could extend ProgressDialog and make it override the drawable internally, however, this was really too complicated for what I needed so I did not do it.

This is some really cool stuff! I needed pretty much the same, but with horizontal gradient from white to transparent. And it is working just fine! Here ist my code:

.gradient{
        /* webkit example */
        background-image: -webkit-gradient(
          linear, right top, left top, from(rgba(255, 255, 255, 1.0)),
          to(rgba(255, 255, 255, 0))
        );

        /* mozilla example - FF3.6+ */
        background-image: -moz-linear-gradient(
          right center,
          rgba(255, 255, 255, 1.0) 20%, rgba(255, 255, 255, 0) 95%
        );

        /* IE 5.5 - 7 */
        filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColorStr=#FFFFFF
        );

        /* IE8 uses -ms-filter for whatever reason... */
        -ms-filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColoStr=#FFFFFF
        );
    }

The easiest way would probably be to put your web resources into the assets folder then call:

webView.loadUrl("file:///android_asset/filename.html");

For Complete Communication between Java and Webview See This

Update: The assets folder is usually the following folder: <project>/src/main/assets This can be changed in the asset folder configuration setting in your <app>.iml file as:

<option name=”ASSETS_FOLDER_RELATIVE_PATH” value=”/src/main/assets” /> See Article Where to place the assets folder in Android Studio

You can try using Scanner if you are using JDK5 or higher.

Scanner scan = new Scanner(file);  
scan.useDelimiter("\\Z");  
String content = scan.next(); 

Or you can also use Guava

String data = Files.toString(new File("path.txt"), Charsets.UTF8);

We developed a page where it loaded a number of images and then performed other functions only after the image was loaded. It was a busy site that generated a lot of traffic. It seems that the following simple script worked on practically all browsers:

$(elem).onload = function() {
    doSomething();
}

BUT THIS IS A POTENTIAL ISSUE FOR IE9!

The ONLY browser we had reported issues on is IE9. Are we not surprised? It seems that the best way to solve the issue there is to not assign a src to the image until AFTER the onload function has been defined, like so:

$(elem).onload = function() {
    doSomething();
}
$(elem).attr('src','theimage.png');

It seems that IE 9 will sometimes not throw the onload event for whatever reason. Other solutions on this page (such as the one from Evan Carroll, for example) still did not work. Logically, that checked if the load state was already successful and triggered the function and if it wasn't, then set the onload handler, but even when you do that we demonstrated in testing that the image could load between those two lines of js thereby appearing not loaded to the first line and then loading before the onload handler is set.

We found that the best way to get what you want is to not define the image's src until you have set the onload event trigger.

We only just recently stopped supporting IE8 so I can't speak for versions prior to IE9, otherwise, out of all the other browsers that were used on the site -- IE10 and 11 as well as Firefox, Chrome, Opera, Safari and whatever mobile browser people were using -- setting the src before assigning the onload handler was not even an issue.

Here are a variety of ways to do this in base R including an alternative aggregate approach. The examples below return means per month, which I think is what you requested. Although, the same approach could be used to return means per person:

Using ave:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

Rate1.mean <- with(my.data, ave(Rate1, Month, FUN = function(x) mean(x, na.rm = TRUE)))
Rate2.mean <- with(my.data, ave(Rate2, Month, FUN = function(x) mean(x, na.rm = TRUE)))

my.data <- data.frame(my.data, Rate1.mean, Rate2.mean)
my.data

Using by:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

by.month <- as.data.frame(do.call("rbind", by(my.data, my.data$Month, FUN = function(x) colMeans(x[,3:4]))))
colnames(by.month) <- c('Rate1.mean', 'Rate2.mean')
by.month <- cbind(Month = rownames(by.month), by.month)

my.data <- merge(my.data, by.month, by = 'Month')
my.data

Using lapply and split:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

ly.mean <- lapply(split(my.data, my.data$Month), function(x) c(Mean = colMeans(x[,3:4])))
ly.mean <- as.data.frame(do.call("rbind", ly.mean))
ly.mean <- cbind(Month = rownames(ly.mean), ly.mean)

my.data <- merge(my.data, ly.mean, by = 'Month')
my.data

Using sapply and split:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')
my.data

sy.mean <- t(sapply(split(my.data, my.data$Month), function(x) colMeans(x[,3:4])))
colnames(sy.mean) <- c('Rate1.mean', 'Rate2.mean')
sy.mean <- data.frame(Month = rownames(sy.mean), sy.mean, stringsAsFactors = FALSE)
my.data <- merge(my.data, sy.mean, by = 'Month')
my.data

Using aggregate:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23

     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

my.summary <- with(my.data, aggregate(list(Rate1, Rate2), by = list(Month), 
                   FUN = function(x) { mon.mean = mean(x, na.rm = TRUE) } ))

my.summary <- do.call(data.frame, my.summary)
colnames(my.summary) <- c('Month', 'Rate1.mean', 'Rate2.mean')
my.summary

my.data <- merge(my.data, my.summary, by = 'Month')
my.data

EDIT: June 28, 2020

Here I use aggregate to obtain the column means of an entire matrix by group where group is defined in an external vector:

my.group <- c(1,2,1,2,2,3,1,2,3,3)

my.data <- matrix(c(   1,    2,    3,    4,    5,
                      10,   20,   30,   40,   50,
                       2,    4,    6,    8,   10,
                      20,   30,   40,   50,   60,
                      20,   18,   16,   14,   12,
                    1000, 1100, 1200, 1300, 1400,
                       2,    3,    4,    3,    2,

                    1001, 2001, 3001, 4001, 5001,
                    1000, 2000, 3000, 4000, 5000), nrow = 10, ncol = 5, byrow = TRUE)
my.data

my.summary <- aggregate(list(my.data), by = list(my.group), FUN = function(x) { my.mean = mean(x, na.rm = TRUE) } )
my.summary

Thanks for the advice. As there is no equivalent in SQL server. I simply created a 2nd field which converted the TimeSpan to ticks and stored that in the DB. I then prevented storing the TimeSpan

public Int64 ValidityPeriodTicks { get; set; }

[NotMapped]
public TimeSpan ValidityPeriod
{
    get { return TimeSpan.FromTicks(ValidityPeriodTicks); }
    set { ValidityPeriodTicks = value.Ticks; }
}

You can detect which button (ok or cancel) pressed by user, because the onunload function called only when the user choise leaveing the page. Althoug in this funcion the possibilities is limited, because the DOM is being collapsed. You can run javascript, but the ajax POST doesn't do anything therefore you can't use this methode for automatic logout. But there is a solution for that. The window.open('logout.php') executed in the onunload funcion, so the user will logged out with a new window opening.

function onunload = (){
    window.open('logout.php');
}

This code called when user leave the page or close the active window and user logged out by 'logout.php'. The new window close immediately when logout php consist of code:

window.close();

Are you calling the web service from client script or on the server side?

You may find sending a content type header to the server will help, e.g.

'application/json; charset=utf-8'

On the client side, I use prototype client side library and there is a contentType parameter when making an Ajax call where you can specify this. I think jQuery has a getJSON method.

 <link rel="shortcut icon" type="image/x-icon" href="FolderName/favicon.ico" />

1. Your favicon.ico must be placed between head tag
2. size : 16 X 16
3. and for Internet Explorer it must be transparent (the outer white part should not visible)

You can also do something like this -

 @RequestParam(value= "i", defaultValue = "20") Optional<Integer> i

Python: You will need to add # - * - coding: UTF-8 - * - (remove the spaces around * ) to the first line of the python file. and then add the following to the text to encode: .encode('ascii', 'xmlcharrefreplace'). This will replace all the unicode characters with it's ASCII equivalent.

As of API 24, sending a file:// URI to another app will throw a FileUriExposedException. Instead, use FileProvider to send a content:// URI:

public File getFile(Context context, String fileName) {
    if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        return null;
    }

    File storageDir = context.getExternalFilesDir(null);
    return new File(storageDir, fileName);
}

public Uri getFileUri(Context context, String fileName) {
    File file = getFile(context, fileName);
    return FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
}

You must also define the FileProvider in your manifest:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mydomain.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Example file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-files-path name="name" path="path" />
</paths>

Replace "name" and "path" as appropriate.

To give the PDF viewer access to the file, you also have to add the FLAG_GRANT_READ_URI_PERMISSION flag to the intent:

private void displayPdf(String fileName) {
    Uri uri = getFileUri(this, fileName);

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(uri, "application/pdf");

    // FLAG_GRANT_READ_URI_PERMISSION is needed on API 24+ so the activity opening the file can read it
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_GRANT_READ_URI_PERMISSION);

    if (intent.resolveActivity(getPackageManager()) == null) {
        // Show an error
    } else {
        startActivity(intent);
    }
}

See the FileProvider documentation for more details.

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

Create rendertemplate.sh:

#!/usr/bin/env bash

eval "echo \"$(cat $1)\""

And template.tmpl:

Hello, ${WORLD}
Goodbye, ${CHEESE}

Render the template:

$ export WORLD=Foo
$ CHEESE=Bar ./rendertemplate.sh template.tmpl 
Hello, Foo
Goodbye, Bar

If you want to treat accented latin characters (eg. à Ñ) as normal letters (ie. avoid matching them too), you'll also need to include the appropriate Unicode range (\u00C0-\u00FF) in your regex, so it would look like this:

/[^a-zA-Z\d\s:\u00C0-\u00FF]/g

• ^ negates what follows
• a-zA-Z matches upper and lower case letters
• \d matches digits
• \s matches white space (if you only want to match spaces, replace this with a space)
• : matches a colon
• \u00C0-\u00FF matches the Unicode range for accented latin characters.

nb. Unicode range matching might not work for all regex engines, but the above certainly works in Javascript (as seen in this pen on Codepen).

nb2. If you're not bothered about matching underscores, you could replace a-zA-Z\d with \w, which matches letters, digits, and underscores.

Checkout their documentation

From the looks of it you could do the following on your docker-compose.yml

volumes:
    - ./:/app

Where ./ is the host directory, and /app is the target directory for the containers.

For the lazy – v3 / v2 / v1

Side note: Syntax remains the same for all versions as of this edit

Just an additional thought on this one for the future. Getting this bug could be the case that one simply hits the delete key or some other key randomly when they have an XML window as the active display and are not paying attention. This has happened to me before with the struts.xml file in my web application. Clumsy elbows ...

The one poit I've noticed to be "the double edged sword" is:

placing the logic in hands of non technical staff

I've seen this work great, when you have one or two multidisciplinary geniuses on the non technical side, but I've also seen the lack of technicity leading to bloat, more bugs, and in general 4x the development/maintenance cost.

Thus you need to consider your user-base seriously.

Here is the regex for what you want with a quantifier to specify at least 1 character and no more than 255 characters

[^a-zA-Z0-9 _]{1,255}

you can use below event of keypress on document load.

 $(document).keypress(function(e) {
            if(e.which == 13) {
               yourfunction();
            }
        });

Thanks

I solved it using the LOCAL option in the command:

LOAD DATA LOCAL INFILE "text.txt" INTO TABLE mytable;

You can find more info here.

If LOCAL is specified, the file is read by the client program on the client host and sent to the server. The file can be given as a full path name to specify its exact location. If given as a relative path name, the name is interpreted relative to the directory in which the client program was started.

Just thought i might add

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA] 

would be the .htaccess and be sure to edit your application/config.php variable in the following manner:

replace

$config['uri_protocol'] = “AUTO” 

with

$config['uri_protocol'] = “REQUEST_URI”

If you would want to put multiple values into the string you could make use of format

nums = [1,2,3]
plot.savefig('hanning{0}{1}{2}.pdf'.format(*nums))

Would result in the string hanning123.pdf. This can be done with any array.

What is <=> ( The 'Spaceship' Operator )

According to the RFC that introduced the operator, $a <=> $b

 -  0 if $a == $b
 - -1 if $a < $b
 -  1 if $a > $b

 - Return 0 if values on either side are equal
 - Return 1 if value on the left is greater
 - Return -1 if the value on the right is greater

Example:

//Comparing Integers

echo 1 <=> 1; //ouputs 0
echo 3 <=> 4; //outputs -1
echo 4 <=> 3; //outputs 1

//String Comparison

echo "x" <=> "x"; // 0
echo "x" <=> "y"; //-1
echo "y" <=> "x"; //1

MORE:

// Integers
echo 1 <=> 1; // 0
echo 1 <=> 2; // -1
echo 2 <=> 1; // 1

// Floats
echo 1.5 <=> 1.5; // 0
echo 1.5 <=> 2.5; // -1
echo 2.5 <=> 1.5; // 1

// Strings
echo "a" <=> "a"; // 0
echo "a" <=> "b"; // -1
echo "b" <=> "a"; // 1

echo "a" <=> "aa"; // -1
echo "zz" <=> "aa"; // 1

// Arrays
echo [] <=> []; // 0
echo [1, 2, 3] <=> [1, 2, 3]; // 0
echo [1, 2, 3] <=> []; // 1
echo [1, 2, 3] <=> [1, 2, 1]; // 1
echo [1, 2, 3] <=> [1, 2, 4]; // -1

// Objects
$a = (object) ["a" => "b"]; 
$b = (object) ["a" => "b"]; 
echo $a <=> $b; // 0

As far as I know, a browser session doesn't have an id.

If you mean the server session, that is usually stored in a cookie. The cookie that ASP.NET stores, for example, is named "ASP.NET_SessionId".

You have to declare your functions before main()

(or declare the function prototypes before main())

As it is, the compiler sees my_print (my_string); in main() as a function declaration.

Move your functions above main() in the file, or put:

void my_print (char *);
void my_print2 (char *);

Above main() in the file.

This will work fine for you

Lexeme is basically the unit of a token and it is basically sequence of characters that matches the token and helps to break the source code into tokens.

For example: If the source is x=b, then the lexemes would be x, =, b and the tokens would be <id, 0>, <=>, <id, 1>.

Among several options for shading and tinting:

• For shades, multiply each component by 1/4, 1/2, 3/4, etc., of its previous value. The smaller the factor, the darker the shade.

• For tints, calculate (255 - previous value), multiply that by 1/4, 1/2, 3/4, etc. (the greater the factor, the lighter the tint), and add that to the previous value (assuming each.component is a 8-bit integer).

Note that color manipulations (such as tints and other shading) should be done in linear RGB. However, RGB colors specified in documents or encoded in images and video are not likely to be in linear RGB, in which case a so-called inverse transfer function needs to be applied to each of the RGB color's components. This function varies with the RGB color space. For example, in the sRGB color space (which can be assumed if the RGB color space is unknown), this function is roughly equivalent to raising each sRGB color component (ranging from 0 through 1) to a power of 2.2. (Note that "linear RGB" is not an RGB color space.)

See also Violet Giraffe's comment about "gamma correction".

Another approach to this issue could be to create a self extracting executable (.exe) using something like winzip and use this as the install vector rather than the zip file. Similarly, you could use NSIS to create an executable installer and use that instead of the zip.

This should do the trick for you: put include tag inside of a block section.

page1.html:

{% extends "base1.html" %}

{% block foo %}
   {% include "commondata.html" %}
{% endblock %}

page2.html:

{% extends "base2.html" %}

{% block bar %}
   {% include "commondata.html" %}
{% endblock %}

This can be achieved with the onresize property of the GlobalEventHandlers interface in JavaScript, by assigning a function to the onresize property, like so:

window.onresize = functionRef;

The following code snippet demonstrates this, by console logging the innerWidth and innerHeight of the window whenever it's resized. (The resize event fires after the window has been resized)

function resize() {_x000D_
  console.log("height: ", window.innerHeight, "px");_x000D_
  console.log("width: ", window.innerWidth, "px");_x000D_
}_x000D_
_x000D_
window.onresize = resize;

<p>In order for this code snippet to work as intended, you will need to either shrink your browser window down to the size of this code snippet, or fullscreen this code snippet and resize from there.</p>

There is the wget command or the curl.

You can now use the file you downloaded with wget. Or you can handle a stream with curl.

Ran in to this problem a while ago. Website couldn't access video file on local PC due to security settings (understandable really) ONLY way I could get around it was to run a webserver on the local PC (server2Go) and all references to the video file from the web were to the localhost/video.mp4

<div id="videoDiv">
     <video id="video" src="http://127.0.0.1:4001/videos/<?php $videoFileName?>" width="70%" controls>
    </div>
<!--End videoDiv-->

Not an ideal solution but worked for me.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

Use Except:

var firstNotSecond = list1.Except(list2).ToList();
var secondNotFirst = list2.Except(list1).ToList();

I suspect there are approaches which would actually be marginally faster than this, but even this will be vastly faster than your O(N * M) approach.

If you want to combine these, you could create a method with the above and then a return statement:

return !firstNotSecond.Any() && !secondNotFirst.Any();

One point to note is that there is a difference in results between the original code in the question and the solution here: any duplicate elements which are only in one list will only be reported once with my code, whereas they'd be reported as many times as they occur in the original code.

For example, with lists of [1, 2, 2, 2, 3] and [1], the "elements in list1 but not list2" result in the original code would be [2, 2, 2, 3]. With my code it would just be [2, 3]. In many cases that won't be an issue, but it's worth being aware of.

There are different ways to do this some of them has given. implode(), join(), var_export(), print_r(), serialize(), json_encode()exc... You can also write your own function without these:

A For() loop is very useful. You can add your array's value to another variable like this:

<?php
    $dizi=array('mother','father','child'); //This is array

    $sayi=count($dizi);
    for ($i=0; $i<$sayi; $i++) {
        $dizin.=("'$dizi[$i]',"); //Now it is string...
    }
         echo substr($dizin,0,-1); //Write it like string :D
?>

In this code we added $dizi's values and comma to $dizin:

$dizin.=("'$dizi[$i]',");

Now

$dizin = 'mother', 'father', 'child',

It's a string, but it has an extra comma :)

And then we deleted the last comma, substr($dizin, 0, -1);

Output:

'mother','father','child'

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

.. rst2html.py README README.html
.. contents::

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

I was getting a similar error on npm install on a local installation:

npm ERR! enoent ENOENT: no such file or directory, stat '[path/to/local/installation]/node_modules/grunt-contrib-jst'

I am not sure what was causing the error, but I had recently installed a couple of new node modules locally, upgraded node with homebrew, and ran 'npm update -g'.

The only way I was able to resolve the issue was to delete the local node_modules directory entirely and run npm install again:

cd [path/to/local/installation]
npm rm -rdf node_modules
npm install

wget is capable of doing what you are asking. Just try the following:

wget -p -k http://www.example.com/

The -p will get you all the required elements to view the site correctly (css, images, etc). The -k will change all links (to include those for CSS & images) to allow you to view the page offline as it appeared online.

From the Wget docs:

‘-k’
‘--convert-links’
After the download is complete, convert the links in the document to make them
suitable for local viewing. This affects not only the visible hyperlinks, but
any part of the document that links to external content, such as embedded images,
links to style sheets, hyperlinks to non-html content, etc.

Each link will be changed in one of the two ways:

    The links to files that have been downloaded by Wget will be changed to refer
    to the file they point to as a relative link.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
    downloaded, then the link in doc.html will be modified to point to
    ‘../bar/img.gif’. This kind of transformation works reliably for arbitrary
    combinations of directories.

    The links to files that have not been downloaded by Wget will be changed to
    include host name and absolute path of the location they point to.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
    ../bar/img.gif), then the link in doc.html will be modified to point to
    http://hostname/bar/img.gif. 

Because of this, local browsing works reliably: if a linked file was downloaded,
the link will refer to its local name; if it was not downloaded, the link will
refer to its full Internet address rather than presenting a broken link. The fact
that the former links are converted to relative links ensures that you can move
the downloaded hierarchy to another directory.

Note that only at the end of the download can Wget know which links have been
downloaded. Because of that, the work done by ‘-k’ will be performed at the end
of all the downloads. 

With find and cp only:

mkdir /tmp/targetdir
cd sourcedir
find . -type f -name '*.zip' -exec cp -p --parents {} /tmp/targetdir ";"
find . -type f -name '*.txt' -exec cp -p --parents {} /tmp/targetdir ";"

Example in Swift, picturing the foundry's explanation above and the Apple's documentation:

1. Basing on the Apple's documentation and the foundry's explanation above (correcting some errors), presentViewController version using delegate design pattern:

ViewController.swift

import UIKit

protocol ViewControllerProtocol {
    func dismissViewController1AndPresentViewController2()
}

class ViewController: UIViewController, ViewControllerProtocol {

    @IBAction func goToViewController1BtnPressed(sender: UIButton) {
        let vc1: ViewController1 = self.storyboard?.instantiateViewControllerWithIdentifier("VC1") as ViewController1
        vc1.delegate = self
        vc1.modalTransitionStyle = UIModalTransitionStyle.FlipHorizontal
        self.presentViewController(vc1, animated: true, completion: nil)
    }

    func dismissViewController1AndPresentViewController2() {
        self.dismissViewControllerAnimated(false, completion: { () -> Void in
            let vc2: ViewController2 = self.storyboard?.instantiateViewControllerWithIdentifier("VC2") as ViewController2
            self.presentViewController(vc2, animated: true, completion: nil)
        })
    }

}

ViewController1.swift

import UIKit

class ViewController1: UIViewController {

    var delegate: protocol<ViewControllerProtocol>!

    @IBAction func goToViewController2(sender: UIButton) {
        self.delegate.dismissViewController1AndPresentViewController2()
    }

}

ViewController2.swift

import UIKit

class ViewController2: UIViewController {

}

2. Basing on the foundry's explanation above (correcting some errors), pushViewController version using delegate design pattern:

ViewController.swift

import UIKit

protocol ViewControllerProtocol {
    func popViewController1AndPushViewController2()
}

class ViewController: UIViewController, ViewControllerProtocol {

    @IBAction func goToViewController1BtnPressed(sender: UIButton) {
        let vc1: ViewController1 = self.storyboard?.instantiateViewControllerWithIdentifier("VC1") as ViewController1
        vc1.delegate = self
        self.navigationController?.pushViewController(vc1, animated: true)
    }

    func popViewController1AndPushViewController2() {
        self.navigationController?.popViewControllerAnimated(false)
        let vc2: ViewController2 = self.storyboard?.instantiateViewControllerWithIdentifier("VC2") as ViewController2
        self.navigationController?.pushViewController(vc2, animated: true)
    }

}

ViewController1.swift

import UIKit

class ViewController1: UIViewController {

    var delegate: protocol<ViewControllerProtocol>!

    @IBAction func goToViewController2(sender: UIButton) {
        self.delegate.popViewController1AndPushViewController2()
    }

}

ViewController2.swift

import UIKit

class ViewController2: UIViewController {

}

Your best bet is to have both repos on your local machine and use the linux diff command with the two directories as parameters:

diff -r repo-A repo-B

Note that Git 1.9/2.0 (Q1 2014) has removed that limitation.
See commit 82fba2b, from Nguy?n Thái Ng?c Duy (pclouds):

Now that git supports data transfer from or to a shallow clone, these limitations are not true anymore.

The documentation now reads:

--depth <depth>::

Create a 'shallow' clone with a history truncated to the specified number of revisions.

That stems from commits like 0d7d285, f2c681c, and c29a7b8 which support clone, send-pack /receive-pack with/from shallow clones.
smart-http now supports shallow fetch/clone too.

All the details are in "shallow.c: the 8 steps to select new commits for .git/shallow".

Update June 2015: Git 2.5 will even allow for fetching a single commit!
(Ultimate shallow case)

Update January 2016: Git 2.8 (Mach 2016) now documents officially the practice of getting a minimal history.
See commit 99487cf, commit 9cfde9e (30 Dec 2015), commit 9cfde9e (30 Dec 2015), commit bac5874 (29 Dec 2015), and commit 1de2e44 (28 Dec 2015) by Stephen P. Smith (``).
^{(Merged by Junio C Hamano -- gitster -- in commit 7e3e80a, 20 Jan 2016)}

This is "Documentation/user-manual.txt"

A <<def_shallow_clone,shallow clone>> is created by specifying the git-clone --depth switch.
The depth can later be changed with the git-fetch --depth switch, or full history restored with --unshallow.

Merging inside a <<def_shallow_clone,shallow clone>> will work as long as a merge base is in the recent history.
Otherwise, it will be like merging unrelated histories and may have to result in huge conflicts.
This limitation may make such a repository unsuitable to be used in merge based workflows.

Update 2020:

• git 2.11.1 introduced option git fetch --shallow-exclude= to prevent fetching all history
• git 2.11.1 introduced option git fetch --shallow-since= to prevent fetching old commits.

For more on the shallow clone update process, see "How to update a git shallow clone?".

As commented by Richard Michael:

to backfill history: git pull --unshallow

And Olle Härstedt adds in the comments:

To backfill part of the history: git fetch --depth=100.

charAt gets a character from a string, and you can switch on them since char is an integer type.

So to switch on the first char in the String hello,

switch (hello.charAt(0)) {
  case 'a': ... break;
}

You should be aware though that Java chars do not correspond one-to-one with code-points. See codePointAt for a way to reliably get a single Unicode codepoints.

One another way without regex:

function trimLeadingZerosSubstr(str) {
    var xLastChr = str.length - 1, xChrIdx = 0;
    while (str[xChrIdx] === "0" && xChrIdx < xLastChr) {
        xChrIdx++;
    }
    return xChrIdx > 0 ? str.substr(xChrIdx) : str;
}

With short string it will be more faster than regex (jsperf)

I know this is very old and possibly talking about an older version of Visual studio and so this might not have been an option before but anyway, my way would be when at a breakpoint use the locals window to see all current variable values ( Debug >> Windows >> Locals )

The element cannot directly inherit from <body> tag. You can try to put it in a <dir style="padding-left:0px;"></dir> tag.

I don't think that has any meaning in SQL. You might be looking at Prepared Statements in JDBC or something. In that case, the question marks are placeholders for parameters to the statement.

From "Find duplicate rows with PostgreSQL" here's smart solution:

select * from (
  SELECT id,
  ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY id asc) AS Row
  FROM tbl
) dups
where 
dups.Row > 1

$('#submit').click(function(){
   if($('#myMessage').val() == ''){
      alert('Input can not be left blank');
   }
});

Update

If you don't want whitespace also u can remove them using jQuery.trim()

Description: Remove the whitespace from the beginning and end of a string.

$('#submit').click(function(){
   if($.trim($('#myMessage').val()) == ''){
      alert('Input can not be left blank');
   }
});

In Bootstrap 3 they do not have separate classes for different styles of labels.

http://getbootstrap.com/components/

However, you can customize bootstrap classes that way. In your css file

.lb-sm {
  font-size: 12px;
}

.lb-md {
  font-size: 16px;
}

.lb-lg {
  font-size: 20px;
}

Alternatively, you can use header tags to change the sizes. For example, here is a medium sized label and a small-sized label

<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<h3>Example heading <span class="label label-default">New</span></h3>_x000D_
<h6>Example heading <span class="label label-default">New</span></h6>

They might add size classes for labels in future Bootstrap versions.

public static void main(string [] args)

public -its the access specifier means from every where we can access it; static -access modifier means we can call this method directly using a class name without creating an object of it; void- its the return type; main- method name string [] args - it accepts only string type of argument... and stores it in a string array

Based on @ooZman 's answer above, this seems to work for PostgreSQL v12 when you need to INSERT with the next value of a "sequence" (akin to auto_increment) without goofing anything up in your table(s) counter(s). (Note: I haven't tested it in more complex DB cluster configurations though...)

Psuedo Code

$insert_next_id = $return_result->query(" select (setval('"your_id_seq"', (select nextval('"your_id_seq"')) - 1, true)) +1; ")

Ideally, margins in CSS containers should collapse, so you can define a parent container which sets its margins(s) to the minimum you want, and then use the margin(s) you want for the child, and the content of the child will use the larger margins between the parent and child margin:

• if the child margin(s) are smaller than the parent margin(s)+its padding(s), then the child margins(s) will have no effect.

• if the child margin(s) are larger than the parent margin(s)+its padding(s), then the parent padding(s) should be increased to fit.

This is still frequently not working as intended in CSS: currently CSS allows margin(s) of a child to collapse into the margin(s) of the parent (extending them if necesary), only if the parent defines NO padding and NO border and no intermediate sibling content exist in the parent between the child and the begining of the content box of the parent; however there may be floatting or positioned sibling elements, which are ignored for computing margins, unless they use "clear:" to also extend the parent's content-box and compltely fit their own content vertically in it (only the parent's height of the content-box is increased for the top-to-bottom or bottom-to-top block-direction of its content box, or only the parent's width for the left-to-right or right-to-left block-direction; the inline-direction of the parent's content-box plays no role) .

So if the parent defines only 1px of padding, or only 1px of border, then this stops the child from collapsing its margin into the parent's margin. Instead the child margins will take effect from the content box of the parent (or the border box of the intermediate sibling content if there's any one). This means that any non-null border or non-null padding in the parent is treated by the child as if this was a sibling content in the same parent.

So this simple solution should work: use an additional parent without any border or padding to set the minimum margin to nest the child element in it; you can still add borders or paddings to the child (if needed) where you'll defining its own secondary margin (collapsing into the parent(s) margins) !

Note that a child element may collapse its margin(s) into several levels of parents ! This means that you can define several minimums (e.g. for the minimum between 3 values, use two levels of parents to contain the child).

Sometimes 3 or more values are needed to account for: the viewport width, the document width, the section container width, the presence or absence of external floats stealing space in the container, and the minimum width needed for the child content itself. All these widths may be variable and may depend as well on the kind of browser used (including its accessibility settings, such as text zoom, or "Hi-DPI" adjustments of sizes in renderers depending on capabilities of the target viewing device, or sometimes because there's a user-tunable choice of layouts such as personal "skins" or other user's preferences, or the set of available fonts on the final rendering host, which means that exact font sizes are hard to predict safely, to match exact sizes in "pixels" for images or borders ; as well users have a wide variety of screen sizes or paper sizes if printing, and orientations ; scrolling is also not even available or possible to compensate, and truncation of overflowing contents is most often undesirable; as well using excessive "clears" is wasting space and makes the rendered document much less accessible).

We need to save space, without packing too much info and keeping clarity fore readers, and ease of navigation : a layout is a constant tradeoff, between saving space and showing more information at once to avoid additional scrolling or navigation to other pages, and keeping the packed info displayed easy to navigate or interact with).

But HTML is often not enough flexible for all goals, and even if it offers some advanced features, they becomes difficult to author or to maintain/change the documents (or the infos they contain), or readapt the content later for other goals or presentations. Keeping things simple avoids this issue and if we use these simple tricks that have nearly no cost and are easy to understand, we should use them (this will always save lot of precious time, including for web designers).

For people that are using PDO statements

$query = $db->prepare('show tables');
$query->execute();

while($rows = $query->fetch(PDO::FETCH_ASSOC)){
     var_dump($rows);
}

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

iBeacon Profile contains 31 Bytes which includes the followings

1. Prefix - 9 Bytes - which include s the adv data and Manufacturer data
2. UUID - 16 Bytes
3. Major - 2 Bytes
4. Minor - 2 Bytes
5. TxPower - 1 Byte

One can simply use java.bean.ConstructorProperties annotation - it's much less verbose and Jackson also accepts it. For example :

  import java.beans.ConstructorProperties;

  @ConstructorProperties({"answer","closed","language","interface","operation"})
  public DialogueOutput(String answer, boolean closed, String language, String anInterface, String operation) {
    this.answer = answer;
    this.closed = closed;
    this.language = language;
    this.anInterface = anInterface;
    this.operation = operation;
  }

One possible reason for this error is: your annual subscription has been renewed. Once the subscription is renewed, all devices related to the active provision profiles will be detached.

1. The admin must reactivate the list of devices for the new subscribed year.
2. The admin must delete last year provision profiles. (all are useless).
3. The admin must regenerate new provision profiles for the new year with the list of devices of his choice.

After this, rebuild project with Xcode and the error will disappear.

Some dude has come up with a smart preprocessor idea in this post

Easy way to use variables of enum types as string in C?

Fellas, I know this is old but hey I've this solution which I think works better than all. First and foremost overcomes the Case Sensitivity that the jquery :contains() is shipped with:

var text = "text";

var search = $( "ul li label" ).filter( function ()
{
    return $( this ).text().toLowerCase().indexOf( text.toLowerCase() ) >= 0;
}).first(); // Returns the first element that matches the text. You can return the last one with .last()

Hope someone in the near future finds it helpful.

Depending on what sort of risks you will accept and how well you know and trust the data, you can use simplistic variable interpolation.

$: x="
    this
    is
       variably indented
    stuff
   "
$: echo "$x" # preserves the newlines and spacing

    this
    is
       variably indented
    stuff

$: echo $x # no quotes, stacks it "neatly" with minimal spacing
this is variably indented stuff

Topic is a bit old, but since the scripts here detect Firefox as a False Positive (EDGE v12), here is the version I use:

function isIEorEDGE(){
  if (navigator.appName == 'Microsoft Internet Explorer'){
    return true; // IE
  }
  else if(navigator.appName == "Netscape"){                       
     return navigator.userAgent.indexOf('.NET') > -1; // Only Edge uses .NET libraries
  }       

  return false;
}

which of course can be written in a more concise way:

function isIEorEDGE(){
  return navigator.appName == 'Microsoft Internet Explorer' || (navigator.appName == "Netscape" && navigator.userAgent.indexOf('.NET') > -1);
}

On Windows 10 this worked for me for VIM and VI using git bash

"Esc" + ":wq!"

or

"Esc" + ":q!"

What you are possibly looking for is map(). You can "convert" the objects in a stream to another by mapping this way:

...
 .map(userMeal -> new UserMealExceed(...))
...

ViewTreeObserver and onWindowFocusChanged() are not so necessary at all.

If you inflate the TextView as layout and/or put some content in it and set LayoutParams then you can use getMeasuredHeight() and getMeasuredWidth().

BUT you have to be careful with LinearLayouts (maybe also other ViewGroups). The issue there is, that you can get the width and height after onWindowFocusChanged() but if you try to add some views in it, then you can't get that information until everything have been drawn. I was trying to add multiple TextViews to LinearLayouts to mimic a FlowLayout (wrapping style) and so couldn't use Listeners. Once the process is started, it should continue synchronously. So in such case, you might want to keep the width in a variable to use it later, as during adding views to layout, you might need it.

You could always do echo "".

e.g.

echo "Hello"
echo ""
echo "World"

It should be:

$when(((tdata.Age == "" ) & (tdata.Survived == "0")), mean_age_0)

rake routes | grep <specific resource name>

displays resource specific routes, if it is a pretty long list of routes.

We can't reference the result of an aggregate function (for example MAX() ) in a WHERE clause of the same SELECT.

The normative pattern for solving this type of problem is to use an inline view, something like this:

SELECT t.firstName
     , t.Lastname
     , t.id
  FROM mytable t
  JOIN ( SELECT MAX(mx.id) AS max_id
           FROM mytable mx
       ) m
    ON m.max_id = t.id

This is just one way to get the specified result. There are several other approaches to get the same result, and some of those can be much less efficient than others. Other answers demonstrate this approach:

 WHERE t.id = (SELECT MAX(id) FROM ... )

Sometimes, the simplest approach is to use an ORDER BY with a LIMIT. (Note that this syntax is specific to MySQL)

SELECT t.firstName
     , t.Lastname
     , t.id
  FROM mytable t
 ORDER BY t.id DESC
 LIMIT 1

Note that this will return only one row; so if there is more than one row with the same id value, then this won't return all of them. (The first query will return ALL the rows that have the same id value.)

This approach can be extended to get more than one row, you could get the five rows that have the highest id values by changing it to LIMIT 5.

Note that performance of this approach is particularly dependent on a suitable index being available (i.e. with id as the PRIMARY KEY or as the leading column in another index.) A suitable index will improve performance of queries using all of these approaches.

Probably not the best solution, but before I came here I just made this on the fly to keep working without having a quick break from study.

def raw_input(x):
  input(x)

Then when I run raw_input('Enter your first name: ') on the script I was working on, it captures it as does input() would.

There may be a reason not to do this, that I haven't come across yet!

The name open addressing refers to the fact that the location ("address") of the element is not determined by its hash value. (This method is also called closed hashing).

In separate chaining, each bucket is independent, and has some sort of ADT (list, binary search trees, etc) of entries with the same index. In a good hash table, each bucket has zero or one entries, because we need operations of order O(1) for insert, search, etc.

This is a example of separate chaining using C++ with a simple hash function using mod operator (clearly, a bad hash function)

With pure JavaScript:

console.log(window.location.href)

Using Angular:

this.router.url

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
    template: 'The href is: {{href}}'
    /*
    Other component settings
    */
})
export class Component {
    public href: string = "";

    constructor(private router: Router) {}

    ngOnInit() {
        this.href = this.router.url;
        console.log(this.router.url);
    }
}

I've also implemented a robust, open source, easy to use and highly customizable PullToRefresh library for Android. You can replace your ListView with the PullToRefreshListView as described in the documentation on the project page.

https://github.com/erikwt/PullToRefresh-ListView

If your coloumn is text and not varchar, then you can use this:

SELECT SUBSTRING(@String, 1, NULLIF(DATALENGTH(@String)-1,-1))

Use Insert method: list.Insert(0, item);

You need use Stream to send file (archive) in a response, what is more you have to use appropriate Content-type in your response header.

There is an example function that do it:

const fs = require('fs');

// Where fileName is name of the file and response is Node.js Reponse. 
responseFile = (fileName, response) => {
  const filePath =  "/path/to/archive.rar" // or any file format

  // Check if file specified by the filePath exists 
  fs.exists(filePath, function(exists){
      if (exists) {     
        // Content-type is very interesting part that guarantee that
        // Web browser will handle response in an appropriate manner.
        response.writeHead(200, {
          "Content-Type": "application/octet-stream",
          "Content-Disposition": "attachment; filename=" + fileName
        });
        fs.createReadStream(filePath).pipe(response);
      } else {
        response.writeHead(400, {"Content-Type": "text/plain"});
        response.end("ERROR File does not exist");
      }
    });
  }
}

The purpose of the Content-Type field is to describe the data contained in the body fully enough that the receiving user agent can pick an appropriate agent or mechanism to present the data to the user, or otherwise deal with the data in an appropriate manner.

"application/octet-stream" is defined as "arbitrary binary data" in RFC 2046, purpose of this content-type is to be saved to disk - it is what you really need.

"filename=[name of file]" specifies name of file which will be downloaded.

For more information please see this stackoverflow topic.

As previously was mentioned you can use next approaches to find file location

//code
Realm.Configuration.defaultConfiguration.fileURL 

//lldb
(lldb) po Realm.Configuration.defaultConfiguration.fileURL

or you can manually find it:

//Simulator
/Users/<username>/Library/Developer/CoreSimulator/Devices/<simulator-uuid>/data/Containers/Data/Application/<application-uuid>/Documents/

//for example
/Users/alex/Library/Developer/CoreSimulator/Devices/E1D084B0-CD97-41B4-871F-E131CA33F635/data/Containers/Data/Application/373721C7-2381-4E3D-9ABC-2147F748322F/Documents/

//iPhone (download a copy)
Xcode -> Window -> Devices and Simulators -> Devices -> <select device and app> -> App container actions -> Download Container... -> <selectfolder and navigate to it (.xcappdata)> -> Right Click -> Show Package Consents -> AppData -> Documents

*Please note that if you set file name for realm and it has some other extension than .realm RealmStudio does not open it by default

Since the id of the connect button is now changed to "colab-connect-button", the following code can be used to keep clicking on the button.

function ClickConnect(){
    console.log("Clicked on connect button"); 
    document.querySelector("colab-connect-button").click()
}
setInterval(ClickConnect,60000)

If still, this doesn't work, then follow the steps given below:

1. Right-click on the connect button (on the top-right side of the colab)
2. Click on inspect
3. Get the HTML id of the button and substitute in the following code

function ClickConnect(){
    console.log("Clicked on connect button"); 
    document.querySelector("Put ID here").click() // Change id here
}
setInterval(ClickConnect,60000)

time.second helps a lot put that at the top of your python.

1. To properly purge the queue of waiting tasks you have to stop all the workers (http://celery.readthedocs.io/en/latest/faq.html#i-ve-purged-messages-but-there-are-still-messages-left-in-the-queue):

$ sudo rabbitmqctl stop

or (in case RabbitMQ/message broker is managed by Supervisor):

$ sudo supervisorctl stop all

2. ...and then purge the tasks from a specific queue:

$ cd <source_dir>
$ celery amqp queue.purge <queue name>

3. Start RabbitMQ:

$ sudo rabbitmqctl start

or (in case RabbitMQ is managed by Supervisor):

$ sudo supervisorctl start all

Java does not provide very full-featured splitting utilities, so the Guava libraries do:

Iterable<String> pieces = Splitter.fixedLength(3).split(string);

Check out the Javadoc for Splitter; it's very powerful.

Not sure if this is the most elegant solution (this is what I used), but you could scale your data to the range between 0 to 1 and then modify the colorbar:

import matplotlib as mpl
...
ax, _ = mpl.colorbar.make_axes(plt.gca(), shrink=0.5)
cbar = mpl.colorbar.ColorbarBase(ax, cmap=cm,
                       norm=mpl.colors.Normalize(vmin=-0.5, vmax=1.5))
cbar.set_clim(-2.0, 2.0)

With the two different limits you can control the range and legend of the colorbar. In this example only the range between -0.5 to 1.5 is show in the bar, while the colormap covers -2 to 2 (so this could be your data range, which you record before the scaling).

So instead of scaling the colormap you scale your data and fit the colorbar to that.

To sum it up,in object oriented programming, everything is modeled into classes and objects. Classes contain properties and methods. Public, private and protected keywords are used to specify access to these members(properties and methods) of a class from other classes or other .dlls or even other applications.

In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$"); for further information see the javadoc

catch needs to return an observable.

.catch(e => { console.log(e); return Observable.of(e); })

if you'd like to stop the pipeline after a caught error, then do this:

.catch(e => { console.log(e); return Observable.of(null); }).filter(e => !!e)

this catch transforms the error into a null val and then filter doesn't let falsey values through. This will however, stop the pipeline for ANY falsey value, so if you think those might come through and you want them to, you'll need to be more explicit / creative.

edit:

better way of stopping the pipeline is to do

.catch(e => Observable.empty())

You can't write to the HKCR (or HKLM) hives in Vista and newer versions of Windows unless you have administrative privileges. Therefore, you'll either need to be logged in as an Administrator before you run your utility, give it a manifest that says it requires Administrator level (which will prompt the user for Admin login info), or quit changing things in places that non-Administrators shouldn't be playing. :-)

The simplest and most fun way (imo) is glob

foreach (glob("*.*") as $filename) {
    echo $filename."<br />";
}

But the standard way is to use the directory functions.

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: .".$file."<br />";
        }
        closedir($dh);
    }
}

There are also the SPL DirectoryIterator methods. If you are interested

closest() only looks for parents, I'm guessing what you really want is .find()

$(this).closest('.row').children('.column').find('.inputQty').val();

For information MCRYPT_MODE_ECB doesn't use the IV (initialization vector). ECB mode divide your message into blocks and each block is encrypted separately. I really don't recommended it.

CBC mode use the IV to make each message unique. CBC is recommended and should be used instead of ECB.

Example :

<?php
$password = "myPassword_!";
$messageClear = "Secret message";

// 32 byte binary blob
$aes256Key = hash("SHA256", $password, true);

// for good entropy (for MCRYPT_RAND)
srand((double) microtime() * 1000000);
// generate random iv
$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC), MCRYPT_RAND);


$crypted = fnEncrypt($messageClear, $aes256Key);

$newClear = fnDecrypt($crypted, $aes256Key);

echo
"IV:        <code>".$iv."</code><br/>".
"Encrypred: <code>".$crypted."</code><br/>".
"Decrypred: <code>".$newClear."</code><br/>";

function fnEncrypt($sValue, $sSecretKey) {
    global $iv;
    return rtrim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $sSecretKey, $sValue, MCRYPT_MODE_CBC, $iv)), "\0\3");
}

function fnDecrypt($sValue, $sSecretKey) {
    global $iv;
    return rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $sSecretKey, base64_decode($sValue), MCRYPT_MODE_CBC, $iv), "\0\3");
}

You have to stock the IV to decode each message (IV are not secret). Each message is unique because each message has an unique IV.

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

You can get the query parameters when passed in URL using ActivatedRoute as stated below:-

url:- http:/domain.com?test=abc

import { Component } from '@angular/core';
import { ActivatedRoute }     from '@angular/router';

@Component({
  selector: 'my-home'
})
export class HomeComponent {

  constructor(private sharedServices : SharedService,private route: ActivatedRoute) { 
    route.queryParams.subscribe(
      data => console.log('queryParams', data['test']));
  }

}

I know this is an old question, but here is an alternative approach that I have found more useful in some situations. I believe the master.dbo.fn_varbintohexstr function has been available in SQL Server at least since SQL2K. Adding it here just for completeness. Some readers may also find it instructive to look at the source code of this function.

declare @source varbinary(max);
set @source = 0x21232F297A57A5A743894A0E4A801FC3;
select varbin_source = @source
,string_result = master.dbo.fn_varbintohexstr (@source)

Add a third group by adding parens around .*, then replace the subsequence with "number" + m.group(2) + "1". e.g.:

String output = m.replaceFirst("number" + m.group(2) + "1");

#include <termios.h>
#include <stdio.h>

static struct termios old, current;

/* Initialize new terminal i/o settings */
void initTermios(int echo) 
{
  tcgetattr(0, &old); /* grab old terminal i/o settings */
  current = old; /* make new settings same as old settings */
  current.c_lflag &= ~ICANON; /* disable buffered i/o */
  if (echo) {
      current.c_lflag |= ECHO; /* set echo mode */
  } else {
      current.c_lflag &= ~ECHO; /* set no echo mode */
  }
  tcsetattr(0, TCSANOW, &current); /* use these new terminal i/o settings now */
}

/* Restore old terminal i/o settings */
void resetTermios(void) 
{
  tcsetattr(0, TCSANOW, &old);
}

/* Read 1 character - echo defines echo mode */
char getch_(int echo) 
{
  char ch;
  initTermios(echo);
  ch = getchar();
  resetTermios();
  return ch;
}

/* Read 1 character without echo */
char getch(void) 
{
  return getch_(0);
}

/* Read 1 character with echo */
char getche(void) 
{
  return getch_(1);
}

/* Let's test it out */
int main(void) {
  char c;
  printf("(getche example) please type a letter: ");
  c = getche();
  printf("\nYou typed: %c\n", c);
  printf("(getch example) please type a letter...");
  c = getch();

Here is sample of raw pointer iterator.

You shouldn't use iterator class to work with raw pointers!

#include <iostream>
#include <vector>
#include <list>
#include <iterator>
#include <assert.h>

template<typename T>
class ptr_iterator
    : public std::iterator<std::forward_iterator_tag, T>
{
    typedef ptr_iterator<T>  iterator;
    pointer pos_;
public:
    ptr_iterator() : pos_(nullptr) {}
    ptr_iterator(T* v) : pos_(v) {}
    ~ptr_iterator() {}

    iterator  operator++(int) /* postfix */         { return pos_++; }
    iterator& operator++()    /* prefix */          { ++pos_; return *this; }
    reference operator* () const                    { return *pos_; }
    pointer   operator->() const                    { return pos_; }
    iterator  operator+ (difference_type v)   const { return pos_ + v; }
    bool      operator==(const iterator& rhs) const { return pos_ == rhs.pos_; }
    bool      operator!=(const iterator& rhs) const { return pos_ != rhs.pos_; }
};

template<typename T>
ptr_iterator<T> begin(T *val) { return ptr_iterator<T>(val); }


template<typename T, typename Tsize>
ptr_iterator<T> end(T *val, Tsize size) { return ptr_iterator<T>(val) + size; }

Raw pointer range based loop workaround. Please, correct me, if there is better way to make range based loop from raw pointer.

template<typename T>
class ptr_range
{
    T* begin_;
    T* end_;
public:
    ptr_range(T* ptr, size_t length) : begin_(ptr), end_(ptr + length) { assert(begin_ <= end_); }
    T* begin() const { return begin_; }
    T* end() const { return end_; }
};

template<typename T>
ptr_range<T> range(T* ptr, size_t length) { return ptr_range<T>(ptr, length); }

And simple test

void DoIteratorTest()
{
    const static size_t size = 10;
    uint8_t *data = new uint8_t[size];
    {
        // Only for iterator test
        uint8_t n = '0';
        auto first = begin(data);
        auto last = end(data, size);
        for (auto it = first; it != last; ++it)
        {
            *it = n++;
        }

        // It's prefer to use the following way:
        for (const auto& n : range(data, size))
        {
            std::cout << " char: " << static_cast<char>(n) << std::endl;
        }
    }
    {
        // Only for iterator test
        ptr_iterator<uint8_t> first(data);
        ptr_iterator<uint8_t> last(first + size);
        std::vector<uint8_t> v1(first, last);

        // It's prefer to use the following way:
        std::vector<uint8_t> v2(data, data + size);
    }
    {
        std::list<std::vector<uint8_t>> queue_;
        queue_.emplace_back(begin(data), end(data, size));
        queue_.emplace_back(data, data + size);
    }
}

I've seen a lot of inadequate answers while trying to figure this one out. General response has been "you are trying to stop something that hasn't started" or "some other program is running on the port you need".

The problem for me turned out to be my firewall. I hadn't even considered this, but port 8005 (the port used for shutdown, thanks mindas), was blocked. I changed it, and now, no more error. Good luck.

With Xiaomi Redmi note 8 pro (MIUI 10.4.4), Android 9 -

While connecting to Vysor (2.1.2) from Windows PC (via USB cable), received the error message:

"Error installing APK: Failure [INSTALL_FAILED_USER_RESTRICTED]"

even after turning "USB Debugging" On.

So the following settings were required -

• Developer options (On)
• USB debugging (On)
• Install via USB (On)

Leave the following,

• Turn on MIUI optimization (On)
• Verify apps over USB (On)

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } }

Here is a simple sample that shows how to generate random number from closed [min, max] range, while min <= max is true

You can reuse it as field in hole class, also having all Random.class methods in one place

Results example:

RandomUtils random = new RandomUtils();
random.nextInt(0, 0); // returns 0
random.nextInt(10, 10); // returns 10
random.nextInt(-10, 10); // returns numbers from -10 to 10 (-10, -9....9, 10)
random.nextInt(10, -10); // throws assert

Sources:

import junit.framework.Assert;
import java.util.Random;

public class RandomUtils extends Random {

    /**
     * @param min generated value. Can't be > then max
     * @param max generated value
     * @return values in closed range [min, max].
     */
    public int nextInt(int min, int max) {
        Assert.assertFalse("min can't be > then max; values:[" + min + ", " + max + "]", min > max);
        if (min == max) {
            return max;
        }

        return nextInt(max - min + 1) + min;
    }
}

I recorded a macro making a hiperlink. This resulted.

ActiveCell.FormulaR1C1 = "=HYPERLINK(""[Workbook.xlsx]Sheet1!A1"",""CLICK HERE"")"

UrlScan can also remove the server header by using AlternateServerName= under [options].

In your .htaccess you can add:

PHP 5.x

<IfModule mod_php5.c>
    php_value memory_limit 64M
</IfModule>

PHP 7.x

<IfModule mod_php7.c>
    php_value memory_limit 64M
</IfModule>

If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.

If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

I agree with some comments about NOLOCK hint and especially with those saying "use it when it's appropriate". If the application written poorly and is using concurrency inappropriate way – that may cause the lock escalation. Highly transactional table also are getting locked all the time due to their nature. Having good index coverage won't help with retrieving the data, but setting ISOLATION LEVEL to READ UNCOMMITTED does. Also I believe that using NOLOCK hint is safe in many cases when the nature of changes is predictable. For example – in manufacturing when jobs with travellers are going through different processes with lots of inserts of measurements, you can safely execute query against the finished job with NOLOCK hint and this way avoid collision with other sessions that put PROMOTED or EXCLUSIVE locks on the table/page. The data you access in this case is static, but it may reside in a very transactional table with hundreds of millions of records and thousands updates/inserts per minute. Cheers

Resize or Modify a MS SQL Server Table Column with Default Constraint using T-SQL Commands

the solution for such a SQL Server problem is going to be

Dropping or disabling the DEFAULT Constraint on the table column.

Modifying the table column data type and/or data size.

Re-creating or enabling the default constraint back on the sql table column.

I suppose this happens due to the max-width of a modal being set to 500px and max-width of modal-lg is 800px I suppose setting it to auto will make your modal responsive

This is a quick example

plot(rnorm(30), xlab = expression(paste("4"^"th")))

The substring method allows you to specify start and end index:

var str = "xxx_456";
var subStr = str.substring(str.length - 3, str.length);

I have Test your code, this error shows when you already have the DB imported or with some tables with the same name, also the Array error that shows is because you add in in the exec parenthesis, here is the fixed version:

$mysqlPassword ='';
$mysqlHostName ='localhost';
$mysqlImportFilename ='dbbackupmember.sql';

First we get an array of keys for this enum. Then, using the map () function, we convert the data to the desired format. id is obtained from the key, name is obtained from enum by the same key.

const converted = Object.keys(GoalProgressMeasurements).map(key => {
        return {
            id: GoalProgressMeasurements[key],
            name: key,
        };
    });

Try the following:

• Close Eclipse.
• Restart your phone.
• End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.
• Issue kill and start command in \platform-tools\
  • C:\sdk\platform-tools>adb kill-server
  • C:\sdk\platform-tools>adb start-server
• If it says something like 'started successfully', you are good.

see docs: http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.insert.html

using loc = 0 will insert at the beginning

df.insert(loc, column, value)

df = pd.DataFrame({'B': [1, 2, 3], 'C': [4, 5, 6]})

df
Out: 
   B  C
0  1  4
1  2  5
2  3  6

idx = 0
new_col = [7, 8, 9]  # can be a list, a Series, an array or a scalar   
df.insert(loc=idx, column='A', value=new_col)

df
Out: 
   A  B  C

It can be done at easily like as:

     <a id="send-thoughts" href="">Click</a>
     <textarea id="message"></textarea>

        $("a#send-thoughts").click(function() {
            var thought = $("#message").val();
            alert(thought);
        });

On Android, you can use the Uri.parse static method of the android.net.Uri class to do the heavy lifting. If you're doing anything with URIs and Intents you'll want to use it anyways.

You're population is from the server-side. Using the registerclientscript will put the script at the beginning of the form.. you'll want to use RegisterStartupScript(Block) to have the script placed at the end of the page in question.

The former tries to run the script before the text area exists in the dom, the latter will run the script after that element in the page is created.

Then you can write

 a = Counter([0,1,2,1,0])
 b = Counter([0, 1, 1])
 c = a - b
 print list(c.elements())  # [0, 2]

In ReactJS if you are rendering an array of elements you should have a unique key for each those elements. Normally those kinda situations are creating a list.

Example:

function List() {
  const numbers = [0,1,2,3];
 
  return (
    <ul>{numbers.map((n) => <li> {n} </li>)}</ul>
  );
}

 ReactDOM.render(
  <List />,
  document.getElementById('root')
);

In the above example, it creates a dynamic list using li tag, so since li tag does not have a unique key it shows an error.

After fixed:

function List() {
  const numbers = [0,1,2,3];
 
  return (
    <ul>{numbers.map((n) => <li key={n}> {n} </li>)}</ul>
  );
}

 ReactDOM.render(
  <List />,
  document.getElementById('root')
);

Alternative solution when use map when you don't have a unique key (this is not recommended by react eslint ):

function List() {
  const numbers = [0,1,2,3,4,4];
 
  return (
    <ul>{numbers.map((n,i) => <li key={i}> {n} </li>)}</ul>
  );
}

 ReactDOM.render(
  <List />,
  document.getElementById('root')
);

You can turn off Java access restrictions for reflection so that private means nothing.

The setAccessible(true) call does that.

The only restriction is that a ClassLoader may disallow you from doing that.

See Subverting Java Access Protection for Unit Testing (Ross Burton) for a way to do this in Java.

I use the below function to display a readout in firefox console log:

////        make printable string for console readout, recursively
var make_printable_object = function(ar_use)
{
////        internal arguments
var in_tab = arguments[1];
var st_return = arguments[2];
////        default vales when applicable
if (!in_tab) in_tab = 0;
if (!st_return) st_return = "";
////        add depth
var st_tab = "";
for (var i=0; i < in_tab; i++) st_tab = st_tab+"-~-~-";

////        traverse given depth and build string
for (var key in ar_use)
{
    ////        gather return type
    var st_returnType = typeof ar_use[key];
    ////        get current depth display
    var st_returnPrime = st_tab+ "["+key+"] ->"+ar_use[key]+"< is {"+st_returnType+"}";
    ////        remove linefeeds to avoid printout confusion
    st_returnPrime = st_returnPrime.replace(/(\r\n|\n|\r)/gm,"");
    ////        add line feed
    st_return = st_return+st_returnPrime+"\n";
    ////         stop at a depth of 15
    if (in_tab>15) return st_return;
    ////        if current value is an object call this function
    if ( (typeof ar_use[key] == "object") & (ar_use[key] != "null") & (ar_use[key] != null) ) st_return = make_printable_object(ar_use[key], in_tab+1, st_return);


}

////        return complete output
return st_return;

};

Example:

console.log( make_printable_object( some_object ) );

Alternatively, you can just replace:

st_return = st_return+st_returnPrime+"\n";

with

st_return = st_return+st_returnPrime+"<br/>";

to print out in a html page.

Plotly's R API might be useful for you. The graph below is here.

library(plotly)
#add username and key
p <- plotly(username="Username", key="API_KEY")
#generate data
x0 = rnorm(500)
x1 = rnorm(500)+1
#arrange your graph
data0 = list(x=x0,
         name = "Carrots",
         type='histogramx',
         opacity = 0.8)

data1 = list(x=x1,
         name = "Cukes",
         type='histogramx',
         opacity = 0.8)
#specify type as 'overlay'
layout <- list(barmode='overlay',
               plot_bgcolor = 'rgba(249,249,251,.85)')  
#format response, and use 'browseURL' to open graph tab in your browser.
response = p$plotly(data0, data1, kwargs=list(layout=layout))

url = response$url
filename = response$filename

browseURL(response$url)

You can use the for command:

FOR /F "eol=; tokens=2,3* delims=, " %i in (myfile.txt) do @echo %i %j %k

Type

for /?

at the command prompt. Also, you can parse ini files!

In Javascript you can do the following:

Object.keys(ahash)[0];

Similar to Lloyd's answer, but works with any size array.

$missing = array();
$missing[] = 'name';
$missing[] = 'zipcode';
$missing[] = 'phone';

if( is_array($missing) && count($missing) > 0 )
        {
            $result = '';
            $total = count($missing) - 1;
            for($i = 0; $i <= $total; $i++)
            { 
              if($i == $total && $total > 0)
                   $result .= "and ";

              $result .= $missing[$i];

              if($i < $total)
                $result .= ", ";
            }

            echo 'You need to provide your '.$result.'.';
            // Echos "You need to provide your name, zipcode, and phone."
        }

The key difference: NSMutableDictionary can be modified in place, NSDictionary cannot. This is true for all the other NSMutable* classes in Cocoa. NSMutableDictionary is a subclass of NSDictionary, so everything you can do with NSDictionary you can do with both. However, NSMutableDictionary also adds complementary methods to modify things in place, such as the method setObject:forKey:.

You can convert between the two like this:

NSMutableDictionary *mutable = [[dict mutableCopy] autorelease];
NSDictionary *dict = [[mutable copy] autorelease]; 

Presumably you want to store data by writing it to a file. NSDictionary has a method to do this (which also works with NSMutableDictionary):

BOOL success = [dict writeToFile:@"/file/path" atomically:YES];

To read a dictionary from a file, there's a corresponding method:

NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:@"/file/path"];

If you want to read the file as an NSMutableDictionary, simply use:

NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:@"/file/path"];

You may use a delegate to solve this issue. Here is an example that is showing how to update a textBox using diffrent thread

public delegate void UpdateTextCallback(string message);

private void TestThread()
{
    for (int i = 0; i <= 1000000000; i++)
    {
        Thread.Sleep(1000);                
        richTextBox1.Dispatcher.Invoke(
            new UpdateTextCallback(this.UpdateText),
            new object[] { i.ToString() }
        );
    }
}
private void UpdateText(string message)
{
    richTextBox1.AppendText(message + "\n");
}

private void button1_Click(object sender, RoutedEventArgs e)
{
   Thread test = new Thread(new ThreadStart(TestThread));
   test.Start();
}

TestThread method is used by thread named test to update textBox

Migration files must match the pattern *_*.php, or else they won't be found. Since users.php does not match this pattern (it has no underscore), this file will not be found by the migrator.

Ideally, you should be creating your migration files using artisan:

php artisan make:migration create_users_table

This will create the file with the appropriate name, which you can then edit to flesh out your migration. The name will also include the timestamp, to help the migrator determine the order of migrations.

You can also use the --create or --table switches to add a little bit more boilerplate to help get you started:

php artisan make:migration create_users_table --create=users

The documentation on migrations can be found here.

In my case it was my ADBLOCKER! For some reason it was enabled on my localhost and causing this error in Firefox.

Disabling it or uninstalling the plugin should fix this.

In your case, it may not be an adblocker but another Firefox plugin. Test it out in incognito first with no plugins to determine if that is the issue and then systematically disable the plugins until you find the culprit.

You can use event.preventDefault() to avoid this. Read more here: http://api.jquery.com/event.preventDefault/.

Right(A1, Len(A1)-Find("(asterisk)",Substitute(A1, "(space)","(asterisk)",Len(A1)-Len(Substitute(A1,"(space)", "(no space)")))))

Try this. Hope it works.

If you are in .NET stack with MVC with AngularJS, this is what you have to do to remove the '#' from url:

1. Set up your base href in your _Layout page: <head> <base href="/"> </head>

2. Then, add following in your angular app config : $locationProvider.html5Mode(true)

3. Above will remove '#' from url but page refresh won't work e.g. if you are in "yoursite.com/about" page refreash will give you a 404. This is because MVC does not know about angular routing and by MVC pattern it will look for a MVC page for 'about' which does not exists in MVC routing path. Workaround for this is to send all MVC page request to a single MVC view and you can do that by adding a route that catches all

url:

routes.MapRoute(
    name: "App",
    url: "{*url}",
    defaults: new {
        controller = "Home", action = "Index"
    }
);

WPF version:

public class LineSegment
{
    private readonly Vector _offset;
    private readonly Vector _vector;

    public LineSegment(Point start, Point end)
    {
        _offset = (Vector)start;
        _vector = (Vector)(end - _offset);
    }

    public double DistanceTo(Point pt)
    {
        var v = (Vector)pt - _offset;

        // first, find a projection point on the segment in parametric form (0..1)
        var p = (v * _vector) / _vector.LengthSquared;

        // and limit it so it lays inside the segment
        p = Math.Min(Math.Max(p, 0), 1);

        // now, find the distance from that point to our point
        return (_vector * p - v).Length;
    }
}

Consider the following ComplexType AuthorType used by author element

<xsd:complexType name="AuthorType">
  <!-- compositor goes here -->
  <xsd:sequence>

     <xsd:element name="phone" type="tns:Phone"/>
  </xsd:sequence>
  <xsd:attribute name="id" type="tns:AuthorId"/>
</xsd:complexType>
<xsd:element name="author" type="tns:AuthorType"/>

If elementFormDefault="unqualified"

then following XML Instance is valid

<x:author xmlns:x="http://example.org/publishing">
   <name>Aaron Skonnard</name>
   <phone>(801)390-4552</phone>
</x:author>

the authors's name attribute is allowed without specifying the namespace(unqualified). Any elements which are a part of <xsd:complexType> are considered as local to complexType.

if elementFormDefault="qualified"

then the instance should have the local elements qualified

<x:author xmlns:x="http://example.org/publishing">
   <x:name>Aaron Skonnard</name>
   <x:phone>(801)390-4552</phone>
</x:author>

You have to know the structure of your page, because if your canvas is a child of a div which in turn is a child of another div... then the story gets more complicated. Here's my code for a canvas which is inside 2 levels of div s:

canvas.addEventListener("click", function(event) {
var x = event.pageX - (this.offsetLeft + this.parentElement.offsetLeft);
var y = event.pageY - (this.offsetTop + this.parentElement.offsetTop);
console.log("relative x=" + x, "relative y" + y);

});

var data=[];
var $el=$("#my-select");
$el.find('option:selected').each(function(){
    data.push({value:$(this).val(),text:$(this).text()});
});
console.log(data)

I'll Explain how to add an image using Android studio(2.3.3). First you need to add the image into res/drawable folder in the project. Like below

Now in go to activity_main.xml (or any activity you need to add image) and select the Design view. There you can see your Palette tool box on left side. You need to drag and drop ImageView.

It will prompt you Resources dialog box. In there select Drawable under the project section you can see your image. Like below

Select the image you want press Ok you can see the image on the Design view. If you want it configure using xml it would look like below.

<ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/homepage"
        tools:layout_editor_absoluteX="55dp"
        tools:layout_editor_absoluteY="130dp" />

You need to give image location using

app:srcCompat="@drawable/imagename"

Merging and fixing answers from Serj-TM and user3359453 so that it works with both ExpandoObject and DynamicJsonObject. This works for me.

public static bool HasPropertyExist(dynamic settings, string name)
{
    if (settings is System.Dynamic.ExpandoObject)
        return ((IDictionary<string, object>)settings).ContainsKey(name);

    if (settings is System.Web.Helpers.DynamicJsonObject)
    try
    {
        return settings[name] != null;
    }
    catch (KeyNotFoundException)
    {
        return false;
    }


    return settings.GetType().GetProperty(name) != null;
}

On MySQL 5.7 and Ubuntu 16.04, edit the file mysql.cnf.

$ sudo nano /etc/mysql/conf.d/mysql.cnf

Include the sql_mode like the following and save the file.

[mysql]
sql_mode=IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Observe that, in my case, I removed the mode STRICT_TRANS_TABLES and the ONLY_FULL_GROUP_BY.

Doing this, it will save the mode configuration permanently. Differently if you just update the @@sql_mode through MySQL, because it will reset on machine/service restart.

After that, to the modified configuration take in action, restart the mysql service:

$ sudo service mysql restart

Try to access the mysql:

$ mysql -u user_name -p

If you are able to login and access MySQL console, it is ok. Great!

BUT, if like me, you face the error "unknown variable sql_mode", which indicates that sql_mode is an option for mysqld, you will have to go back, edit the file mysql.cnf again and change the [mysql] to [mysqld]. Restart the MySQL service and do a last test trying to login on MySQL console. Here it is!

If you are just storing it for reference, you can store it as a string, but if you want to do a lookup, for example, to see if the IP address is in some table, you need a "canonical representation." Converting the entire thing to a (large) number is the right thing to do. IPv4 addresses can be stored as a long int (32 bits) but you need a 128 bit number to store an IPv6 address.

For example, all these strings are really the same IP address: 127.0.0.1, 127.000.000.001, ::1, 0:0:0:0:0:0:0:1

Think of a GrantedAuthority as being a "permission" or a "right". Those "permissions" are (normally) expressed as strings (with the getAuthority() method). Those strings let you identify the permissions and let your voters decide if they grant access to something.

You can grant different GrantedAuthoritys (permissions) to users by putting them into the security context. You normally do that by implementing your own UserDetailsService that returns a UserDetails implementation that returns the needed GrantedAuthorities.

Roles (as they are used in many examples) are just "permissions" with a naming convention that says that a role is a GrantedAuthority that starts with the prefix ROLE_. There's nothing more. A role is just a GrantedAuthority - a "permission" - a "right". You see a lot of places in spring security where the role with its ROLE_ prefix is handled specially as e.g. in the RoleVoter, where the ROLE_ prefix is used as a default. This allows you to provide the role names withtout the ROLE_ prefix. Prior to Spring security 4, this special handling of "roles" has not been followed very consistently and authorities and roles were often treated the same (as you e.g. can see in the implementation of the hasAuthority() method in SecurityExpressionRoot - which simply calls hasRole()). With Spring Security 4, the treatment of roles is more consistent and code that deals with "roles" (like the RoleVoter, the hasRole expression etc.) always adds the ROLE_ prefix for you. So hasAuthority('ROLE_ADMIN') means the the same as hasRole('ADMIN') because the ROLE_ prefix gets added automatically. See the spring security 3 to 4 migration guide for futher information.

But still: a role is just an authority with a special ROLE_ prefix. So in Spring security 3 @PreAuthorize("hasRole('ROLE_XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')") and in Spring security 4 @PreAuthorize("hasRole('XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')").

Regarding your use case:

Users have roles and roles can perform certain operations.

You could end up in GrantedAuthorities for the roles a user belongs to and the operations a role can perform. The GrantedAuthorities for the roles have the prefix ROLE_ and the operations have the prefix OP_. An example for operation authorities could be OP_DELETE_ACCOUNT, OP_CREATE_USER, OP_RUN_BATCH_JOBetc. Roles can be ROLE_ADMIN, ROLE_USER, ROLE_OWNER etc.

You could end up having your entities implement GrantedAuthority like in this (pseudo-code) example:

@Entity
class Role implements GrantedAuthority {
    @Id
    private String id;

    @ManyToMany
    private final List<Operation> allowedOperations = new ArrayList<>();

    @Override
    public String getAuthority() {
        return id;
    }

    public Collection<GrantedAuthority> getAllowedOperations() {
        return allowedOperations;
    }
}

@Entity
class User {
    @Id
    private String id;

    @ManyToMany
    private final List<Role> roles = new ArrayList<>();

    public Collection<Role> getRoles() {
        return roles;
    }
}

@Entity
class Operation implements GrantedAuthority {
    @Id
    private String id;

    @Override
    public String getAuthority() {
        return id;
    }
}

The ids of the roles and operations you create in your database would be the GrantedAuthority representation, e.g. ROLE_ADMIN, OP_DELETE_ACCOUNT etc. When a user is authenticated, make sure that all GrantedAuthorities of all its roles and the corresponding operations are returned from the UserDetails.getAuthorities() method.

Example: The admin role with id ROLE_ADMIN has the operations OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB assigned to it. The user role with id ROLE_USER has the operation OP_READ_ACCOUNT.

If an admin logs in the resulting security context will have the GrantedAuthorities: ROLE_ADMIN, OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB

If a user logs it, it will have: ROLE_USER, OP_READ_ACCOUNT

The UserDetailsService would take care to collect all roles and all operations of those roles and make them available by the method getAuthorities() in the returned UserDetails instance.

Arrays.setAll() will work for most scenarios:

1. Integer List to primitive int array:

   public static int[] convert(final List<Integer> list)
   {
      final int[] out = new int[list.size()];
      Arrays.setAll(out, list::get);
      return out;
   }
   

2. Integer List (made of Strings) to primitive int array:

   public static int[] convert(final List<String> list)
   {
      final int[] out = new int[list.size()];
      Arrays.setAll(out, i -> Integer.parseInt(list.get(i)));
      return out;
   }
   

3. Integer array to primitive int array:

   public static int[] convert(final Integer[] array)
   {
      final int[] out = new int[array.length];
      Arrays.setAll(out, i -> array[i]);
      return out;
   }
   

4. Primitive int array to Integer array:

   public static Integer[] convert(final int[] array)
   {
      final Integer[] out = new Integer[array.length];
      Arrays.setAll(out, i -> array[i]);
      return out;
   }
   

str.charAt(str.length - 1)

Some browsers allow (as a non-standard extension) you to shorten this to:

str[str.length - 1];

In JavaScript it has no special significance (no more than a or Q anyway). It is just an uninformative variable name.

In jQuery the variable is assigned a copy of the jQuery function. This function is heavily overloaded and means half a dozen different things depending on what arguments it is passed. In this particular example you are passing it a string that contains a selector, so the function means "Create a jQuery object containing the element with the id Text".

For many use cases, the answer you want is:

ys = set(y)
[item for item in x if item not in ys]

This is a hybrid between aaronasterling's answer and quantumSoup's answer.

aaronasterling's version does len(y) item comparisons for each element in x, so it takes quadratic time. quantumSoup's version uses sets, so it does a single constant-time set lookup for each element in x—but, because it converts both x and y into sets, it loses the order of your elements.

By converting only y into a set, and iterating x in order, you get the best of both worlds—linear time, and order preservation.*

However, this still has a problem from quantumSoup's version: It requires your elements to be hashable. That's pretty much built into the nature of sets.** If you're trying to, e.g., subtract a list of dicts from another list of dicts, but the list to subtract is large, what do you do?

If you can decorate your values in some way that they're hashable, that solves the problem. For example, with a flat dictionary whose values are themselves hashable:

ys = {tuple(item.items()) for item in y}
[item for item in x if tuple(item.items()) not in ys]

If your types are a bit more complicated (e.g., often you're dealing with JSON-compatible values, which are hashable, or lists or dicts whose values are recursively the same type), you can still use this solution. But some types just can't be converted into anything hashable.

If your items aren't, and can't be made, hashable, but they are comparable, you can at least get log-linear time (O(N*log M), which is a lot better than the O(N*M) time of the list solution, but not as good as the O(N+M) time of the set solution) by sorting and using bisect:

ys = sorted(y)
def bisect_contains(seq, item):
    index = bisect.bisect(seq, item)
    return index < len(seq) and seq[index] == item
[item for item in x if bisect_contains(ys, item)]

If your items are neither hashable nor comparable, then you're stuck with the quadratic solution.

_{* Note that you could also do this by using a pair of OrderedSet objects, for which you can find recipes and third-party modules. But I think this is simpler.}

_{** The reason set lookups are constant time is that all it has to do is hash the value and see if there's an entry for that hash. If it can't hash the value, this won't work.}

You can't clone it, and how you are going to solve your problem depends on what the source of the data is.

One solution is to read all data from the InputStream into a byte array, and then create a ByteArrayInputStream around that byte array, and pass that input stream into your method.

Edit 1: That is, if the other method also needs to read the same data. I.e you want to "reset" the stream.

I sometimes like using the array_reduce() function to carry out the search. It's similar to array_filter() but does not affect the searched array, allowing you to carry out multiple searches on the same array of objects.

$haystack = array($obj1, $obj2, ...); //some array of objects
$needle = 'looking for me?'; //the value of the object's property we want to find

//carry out the search
$search_results_array = array_reduce(
  $haystack,

  function($result_array, $current_item) use ($needle){
      //Found the an object that meets criteria? Add it to the the result array 
      if ($current_item->someProperty == $needle){
          $result_array[] = $current_item;
      }
      return $result_array;
  },
  array() //initially the array is empty (i.e.: item not found)
);

//report whether objects found
if (count($search_results_array) > 0){
  echo "found object(s): ";
  print_r($search_results_array[0]); //sample object found
} else {
  echo "did not find object(s): ";
}

In Xcode 6.3 and later (including Xcode 7 and 8), console output appears in the Debug area at the bottom of the playground window (similar to where it appears in a project). To show it:

• Menu: View > Debug Area > Show Debug Area (??Y)

• Click the middle button of the workspace-layout widget in the toolbar

  

• Click the triangle next to the timeline at the bottom of the window

  

Anything that writes to the console, including Swift's print statement (renamed from println in Swift 2 beta) shows up there.

In earlier Xcode 6 versions (which by now you probably should be upgrading from anyway), show the Assistant editor (e.g. by clicking the little circle next to a bit in the output area). Console output appears there.

The only way I know is by creating a Windows shortcut to the batch file and then changing its properties to run minimized by default.

The following solution works well when you want to move the text closer to the bullet and even if you have multiple lines of text.

margin-right allows you to move the text closer to the bullet

text-indent ensures that multiple lines of text still line up correctly

li:before {_x000D_
  content: "";_x000D_
  margin-right: -5px; /* Adjust this to move text closer to the bullet */_x000D_
}_x000D_
_x000D_
li {_x000D_
  text-indent: 5px; /* Aligns second line of text */_x000D_
}

<ul>_x000D_
  <li> Item 1 ... </li>_x000D_
  <li> Item 2 ... this item has tons and tons of text that causes a second line! Notice how even the second line is lined up with the first!</li>_x000D_
  <li> Item 3 ... </li>_x000D_
</ul>
