You can use

//noinspection deprecation
return Html.fromHtml(source);

to suppress inspection just for single statement but not the whole method.

I've had the same issue. When I was clicking on item's toggle button in my recyclerView checked Toggle button appeared in every 10th item (for example if it was clicked in item with 0 index, items with 9, 18, 27 indexes were getting clicked too). Firstly, my code in onBindViewHolder was:

if (newsItems.get(position).getBookmark() == 1) {
            holder.getToggleButtonBookmark().setChecked(true);
        }

But then I added Else statement

if (newsItems.get(position).getBookmark() == 1) {
            holder.getToggleButtonBookmark().setChecked(true);
//else statement prevents auto toggling
        } else{
            holder.getToggleButtonBookmark().setChecked(false);
        }

And the problem was solved

This bug is still not fixed in 23.1.1, but a common workaround would be to catch the exception.

Slight change to @rejesh-yadav wonderful answer.

html2canvas now returns a promise.

html2canvas(document.body).then(function (canvas) {
    var img = canvas.toDataURL("image/png");
    var doc = new jsPDF();
    doc.addImage(img, 'JPEG', 10, 10);
    doc.save('test.pdf');        
});

Hope this helps some!

You can also use the jsPDF-AutoTable plugin. You can check out a demo here that uses the following code.

var doc = new jsPDF('p', 'pt');
var elem = document.getElementById("basic-table");
var res = doc.autoTableHtmlToJson(elem);
doc.autoTable(res.columns, res.data);
doc.save("table.pdf");

Try to put

doc.fromHTML($('#target').get(0), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

instead of

doc.fromHTML($('#target').html(), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

I found the solution on this page: https://github.com/MrRio/jsPDF/issues/434 From the user: wangzhixuan

I copy the solution here: // suppose your picture is already in a canvas

      var imgData = canvas.toDataURL('image/png');

      /*
      Here are the numbers (paper width and height) that I found to work. 
      It still creates a little overlap part between the pages, but good enough for me.
      if you can find an official number from jsPDF, use them.
      */
      var imgWidth = 210; 
      var pageHeight = 295;  
      var imgHeight = canvas.height * imgWidth / canvas.width;
      var heightLeft = imgHeight;

      var doc = new jsPDF('p', 'mm');
      var position = 0;

      doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
      heightLeft -= pageHeight;

      while (heightLeft >= 0) {
        position = heightLeft - imgHeight;
        doc.addPage();
        doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
        heightLeft -= pageHeight;
      }
      doc.save( 'file.pdf');?

how about in vuejs how is it applicable?

function onClick() {_x000D_
  var pdf = new jsPDF('p', 'pt', 'letter');_x000D_
  pdf.canvas.height = 72 * 11;_x000D_
  pdf.canvas.width = 72 * 8.5;_x000D_
_x000D_
  pdf.fromHTML(document.body);_x000D_
_x000D_
  pdf.save('test.pdf');_x000D_
};_x000D_
_x000D_
var element = document.getElementById("clickbind");_x000D_
element.addEventListener("click", onClick);

<h1>Dsdas</h1>_x000D_
_x000D_
<a id="clickbind" href="#">Click</a>_x000D_

For Kotlin on fragment just do this

activity?.runOnUiThread(Runnable {
        //on main thread
    })

Instead of using divider in dialog, use the view in the custom layout and set the layout as custom layout in dialog.

custom_popup.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">

    <com.divago.view.TextViewMedium
        android:id="@+id/txtTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:paddingBottom="10dp"
        android:paddingTop="10dp"
        android:text="AlertDialog"
        android:textColor="@android:color/black"
        android:textSize="20sp" />

    <View
        android:id="@+id/border"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_below="@id/txtTitle"
        android:background="@color/txt_dark_grey" />

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/border"
        android:scrollbars="vertical">

        <com.divago.view.TextViewRegular
            android:id="@+id/txtPopup"
            android:layout_margin="15dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </ScrollView>
</RelativeLayout>

activity.java:

public void showPopUp(String title, String text) {

    LayoutInflater inflater = getLayoutInflater();
    View alertLayout = inflater.inflate(R.layout.custom_popup, null);

    TextView txtContent = alertLayout.findViewById(R.id.txtPopup);
    txtContent.setText(text);

    TextView txtTitle = alertLayout.findViewById(R.id.txtTitle);
    txtTitle.setText(title);

    AlertDialog.Builder alert = new AlertDialog.Builder(this);
    alert.setView(alertLayout);
    alert.setCancelable(true);

    alert.setPositiveButton("Done", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });

    AlertDialog dialog = alert.create();
    dialog.show();
}

simply add + "<br />" + is enough for a line break

In the CSS write:

.exampleclass {
    background:#000000;
    opacity: 10; /* you can always adjust this */
}

Simple and easy way to display underline in TextView is:

yourTextView.getPaint().setUnderlineText(true);

And if you want to remove underlining for that view, you can write below code:

yourTextView.getPaint().setUnderlineText(false);

It will work even though you set android:textAllCaps="true"

I found another method: Is necessary to add the "android:maxWidth="40dp"" attribute. Of course, it may not work perfectly, but it gives a line break.

Use Jquery for append the value for creating dynamically

eg:

var user_image1='<img src="{@user_image}" class="img-thumbnail" alt="Thumbnail Image" 
style="width:125px; height:125px">';

$("#userphoto").append(user_image1.replace("{@user_image}","http://127.0.0.1:50075/webhdfs/v1/PATH/"+user_image+"?op=OPEN")); 

HTML :

<div id="userphoto">

Latest update:

Html.fromHtml(string);//deprecated after Android N versions..

Following code give support to android N and above versions...

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
textView.setText(Html.fromHtml(yourHtmlString,Html.FROM_HTML_MODE_LEGACY));
}

else 
{
textView.setText(Html.fromHtml(yourHtmlString));
}

You could also write your own parser to pull the URL of all the images and then dynamically create new imageviews and pass in the urls.

First Convert your string into HTML then convert it into spannable. do as suggest the following codes.

 Spannable spannable = new SpannableString(Html.fromHtml(labelText));
                    
spannable.setSpan(new ForegroundColorSpan(Color.parseColor(color)), spannable.toString().indexOf("•"), spannable.toString().lastIndexOf("•") + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            

Solution

I have implemented a small class with the help of which you can handle long clicks on TextView itself and Taps on the links in the TextView.

Layout

TextView android:id="@+id/text"
                android:layout_width="wrap_content"

Hope this helps! You can find code here.

A lock should be considered to use, such as threading.Lock. See lock-objects for more info.

The accepted answer CAN print 10 by thread1, which is not what you want. You can run the following code to understand the bug more easily.

def thread1(threadname):
    while True:
      if a % 2 and not a % 2:
          print "unreachable."

def thread2(threadname):
    global a
    while True:
        a += 1

Using a lock can forbid changing of a while reading more than one time:

def thread1(threadname):
    while True:
      lock_a.acquire()
      if a % 2 and not a % 2:
          print "unreachable."
      lock_a.release()

def thread2(threadname):
    global a
    while True:
        lock_a.acquire()
        a += 1
        lock_a.release()

If thread using the variable for long time, coping it to a local variable first is a good choice.

There's another method shown at this Google Groups post. In short, you could try detecting whether the extension icon loads successfully. This may be helpful if the extension you're checking for isn't your own.

You can return FileResult with this methods:

1: Return FileStreamResult

    [HttpGet("get-file-stream/{id}"]
    public async Task<FileStreamResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var stream = await GetFileStreamById(id);

        return new FileStreamResult(stream, mimeType)
        {
            FileDownloadName = fileName
        };
    }

2: Return FileContentResult

    [HttpGet("get-file-content/{id}"]
    public async Task<FileContentResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var fileBytes = await GetFileBytesById(id);

        return new FileContentResult(fileBytes, mimeType)
        {
            FileDownloadName = fileName
        };
    }

I was using salesforce apex classes with Eclipse Neon 3.3 for Java.
I found an option "define folding region" on right click in the editor, I selected the block of code i wanted to collapse and selected this property for that code. Now I am seeing + and - symbol to expand and collapse that block of code

Colin Pickard has an excellent answer, but there is one 'watch out' with this. There are instances (I haven't figured out the cause yet) where the total length of the "CMG=........GC=...." entry in the file is different from one excel file to the next. In some cases, this entry will be 137 bytes, and in others it will be 143 bytes. The 137 byte length is the odd one, and if this happens when you create your file with the '1234' password, just create another file, and it should jump to the 143 byte length.

If you try to paste the wrong number of bytes into the file, you will lose your VBA project when you try to open the file with Excel.

EDIT

This is not valid for Excel 2007/2010 files. The standard .xlsx file format is actually a .zip file containing numerous sub-folders with the formatting, layout, content, etc, stored as xml data. For an unprotected Excel 2007 file, you can just change the .xlsx extension to .zip, then open the zip file and look through all the xml data. It's very straightforward.

However, when you password protect an Excel 2007 file, the entire .zip (.xlsx) file is actually encrypted using RSA encryption. It is no longer possible to change the extension to .zip and browse the file contents.

I have included an example here which demonstrates how you might store the mask in a database column as an int, and how you would reinstate the mask later on:

public enum DaysBitMask { Mon=0, Tues=1, Wed=2, Thu = 4, Fri = 8, Sat = 16, Sun = 32 }


DaysBitMask mask = DaysBitMask.Sat | DaysBitMask.Thu;
bool test;
if ((mask & DaysBitMask.Sat) == DaysBitMask.Sat)
    test = true;
if ((mask & DaysBitMask.Thu) == DaysBitMask.Thu)
    test = true;
if ((mask & DaysBitMask.Wed) != DaysBitMask.Wed)
    test = true;

// Store the value
int storedVal = (int)mask;

// Reinstate the mask and re-test
DaysBitMask reHydratedMask = (DaysBitMask)storedVal;

if ((reHydratedMask & DaysBitMask.Sat) == DaysBitMask.Sat)
    test = true;
if ((reHydratedMask & DaysBitMask.Thu) == DaysBitMask.Thu)
    test = true;
if ((reHydratedMask & DaysBitMask.Wed) != DaysBitMask.Wed)
    test = true;

you please open the Navigator view and following step

1. (Window > Show View > Other > General) and find that there is a .settings folder under your project, expand it and then open the file "org.eclipse.wst.common.project.facet.core.xml", make the below changes and save the file.
2. Change the dynamic web module version in this line to 2.5 -
3. Change the Java version in this line to 1.5 or higher - .

depending on who is going to be using your database, for example African names will do with varchar(20) for last name and first name separated. however it is different from nation to nation but for the sake saving your database resources and memory, separate last name and first name fields and use varchar(30) think that will work.

Here is an easier way that can work in some cases. The principle is to add a not visible TextVview in your xml layout and to get its typeFace in the java code.

The layout in the xml file:

 <TextView
        android:text="The classic bread is made of flour hot and salty. The classic bread is made of flour hot and salty. The classic bread is made of flour hot and salty."
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:fontFamily="sans-serif-thin"
        android:id="@+id/textViewDescription"/>

And the java code:

myText.setTypeface(textViewSelectedDescription.getTypeface());

It has worked for me (within a TextSwitcher for example).

In addition to the answer of "dasblinkenlight" I think an example could help. I will only use 8 bits for a better understanding.

x & 1 produces a value that is either 1 or 0, depending on the least significant bit of x: if the last bit is 1, the result of x & 1 is 1; otherwise, it is 0. This is a bitwise AND operation.

This is because 1 will be represented in bits as 00000001. Only the last bit is set to 1. Let's assume x is 185 which will be represented in bits as 10111001. If you apply a bitwise AND operation on x with 1 this will be the result:

00000001
10111001
--------
00000001

The first seven bits of the operation result will be 0 after the operation and will carry no information in this case (see Logical AND operation). Because whatever the first seven bits of the operand x were before, after the operation they will be 0. But the last bit of the operand 1 is 1 and it will reveal if the last bit of operand x was 0 or 1. So in this example the result of the bitwise AND operation will be 1 because our last bit of x is 1. If the last bit would have been 0, then the result would have been also 0, indicating that the last bit of operand x is 0:

00000001
10111000
--------
00000000

x >>= 1 means "set x to itself shifted by one bit to the right". The expression evaluates to the new value of x after the shift

Let's pick the example from above. For x >>= 1 this would be:

10111001
--------
01011100

And for left shift x <<= 1 it would be:

10111001
--------
01110010

Please pay attention to the note of user "dasblinkenlight" in regard to shifts.

Well, take a look, this works, If you have problems please tell me:

No offense folks, but for such a simple problem, you are making things way too complicated. There are a lot of reasons to use Boost. But for something this simple, it's like hitting a fly with a 20# sledge.

void
split( vector<string> & theStringVector,  /* Altered/returned value */
       const  string  & theString,
       const  string  & theDelimiter)
{
    UASSERT( theDelimiter.size(), >, 0); // My own ASSERT macro.

    size_t  start = 0, end = 0;

    while ( end != string::npos)
    {
        end = theString.find( theDelimiter, start);

        // If at end, use length=maxLength.  Else use length=end-start.
        theStringVector.push_back( theString.substr( start,
                       (end == string::npos) ? string::npos : end - start));

        // If at end, use start=maxSize.  Else use start=end+delimiter.
        start = (   ( end > (string::npos - theDelimiter.size()) )
                  ?  string::npos  :  end + theDelimiter.size());
    }
}

For example (for Doug's case),

#define SHOW(I,X)   cout << "[" << (I) << "]\t " # X " = \"" << (X) << "\"" << endl

int
main()
{
    vector<string> v;

    split( v, "A:PEP:909:Inventory Item", ":" );

    for (unsigned int i = 0;  i < v.size();   i++)
        SHOW( i, v[i] );
}

And yes, we could have split() return a new vector rather than passing one in. It's trivial to wrap and overload. But depending on what I'm doing, I often find it better to re-use pre-existing objects rather than always creating new ones. (Just as long as I don't forget to empty the vector in between!)

Reference: http://www.cplusplus.com/reference/string/string/.

(I was originally writing a response to Doug's question: C++ Strings Modifying and Extracting based on Separators (closed). But since Martin York closed that question with a pointer over here... I'll just generalize my code.)

For those working with ant, I use this to indicate a pause of 5 seconds:

<tr>
    <td>pause</td>
    <td>5000</td>
    <td></td>
</tr>

That is, target: 5000 and value empty. As the reference indicates:

pause(waitTime)

Arguments:

• waitTime - the amount of time to sleep (in milliseconds)

Wait for the specified amount of time (in milliseconds)

There are a lot of ways you can call a shell command from a Perl script, such as:

1. back tick ls which captures the output and gives back to you.
2. system system('ls');
3. open

There are 3 location providers in Android.

They are:

gps –> (GPS, AGPS): Name of the GPS location provider. This provider determines location using satellites. Depending on conditions, this provider may take a while to return a location fix. Requires the permission android.permission.ACCESS_FINE_LOCATION.

network –> (AGPS, CellID, WiFi MACID): Name of the network location provider. This provider determines location based on availability of cell tower and WiFi access points. Results are retrieved by means of a network lookup. Requires either of the permissions android.permission.ACCESS_COARSE_LOCATION or android.permission.ACCESS_FINE_LOCATION.

passive –> (CellID, WiFi MACID): A special location provider for receiving locations without actually initiating a location fix. This provider can be used to passively receive location updates when other applications or services request them without actually requesting the locations yourself. This provider will return locations generated by other providers. Requires the permission android.permission.ACCESS_FINE_LOCATION, although if the GPS is not enabled this provider might only return coarse fixes. This is what Android calls these location providers, however, the underlying technologies to make this stuff work is mapped to the specific set of hardware and telco provided capabilities (network service).

The best way is to use the “network” or “passive” provider first, and then fallback on “gps”, and depending on the task, switch between providers. This covers all cases, and provides a lowest common denominator service (in the worst case) and great service (in the best case).

-----------------------Update-----------------------

Now Android have Fused location provider

The Fused Location Provider intelligently manages the underlying location technology and gives you the best location according to your needs. It simplifies ways for apps to get the user’s current location with improved accuracy and lower power usage

Fused location provider provide three ways to fetch location

1. Last Location: Use when you want to know current location once.
2. Request Location using Listener: Use when application is on screen / frontend and require continues location.
3. Request Location using Pending Intent: Use when application in background and require continues location.

--------------------------------------------------------

The Web Storage API provides mechanisms by which browsers can securely store key/value pairs, in a much more intuitive fashion than using cookies. The Web Storage API extends the Window object with two new properties — Window.sessionStorage and Window.localStorage. — invoking one of these will create an instance of the Storage object, through which data items can be set, retrieved, and removed. A different Storage object is used for the sessionStorage and localStorage for each origin (domain).

Storage objects are simple key-value stores, similar to objects, but they stay intact through page loads.

localStorage.colorSetting = '#a4509b';
localStorage['colorSetting'] = '#a4509b';
localStorage.setItem('colorSetting', '#a4509b');

The keys and the values are always strings. To store any type convert it to String and then store it. It's always recommended to use Storage interface methods.

var testObject = { 'one': 1, 'two': 2, 'three': 3 };
// Put the object into storage
localStorage.setItem('testObject', JSON.stringify(testObject));
// Retrieve the object from storage
var retrievedObject = localStorage.getItem('testObject');
console.log('Converting String to Object: ', JSON.parse(retrievedObject));

The two mechanisms within Web Storage are as follows:

• sessionStorage maintains a separate storage area for each given origin^{Same-origin policy} that's available for the duration of the page session (as long as the browser is open, including page reloads and restores).
• localStorage does the same thing, but persists even when the browser is closed and reopened.

Storage « Local storage writes the data to the disk, while session storage writes the data to the memory only. Any data written to the session storage is purged when your app exits.

The maximum storage available is different per browser, but most browsers have implemented at least the w3c recommended maximum storage limit of 5MB.

+----------------+--------+---------+-----------+--------+
|                | Chrome | Firefox | Safari    |  IE    |
+----------------+--------+---------+-----------+--------+
| LocalStorage   | 10MB   | 10MB    | 5MB       | 10MB   |
+----------------+--------+---------+-----------+--------+
| SessionStorage | 10MB   | 10MB    | Unlimited | 10MB   |
+----------------+--------+---------+-----------+--------+

Always catch LocalStorage security and quota exceeded errors

• QuotaExceededError: When storage limits exceeds on this function window.sessionStorage.setItem(key, value);, it throws a "QuotaExceededError" DOMException exception if the new value couldn't be set. (Setting could fail if, e.g., the user has disabled storage for the site, or if the quota has been exceeded.)

  DOMException.QUOTA_EXCEEDED_ERR is 22, example fiddle.

• SecurityError : Uncaught SecurityError: Access to 'localStorage' is denied for this document.

   CHROME:-Privacy and security « Content settings « Cookies « Block third-party cookies.
  

StorageEvent « The storage event is fired on a document's Window object when a storage area changes. When a user agent is to send a storage notification for a Document, the user agent must queue a task to fire an event named storage at the Document object's Window object, using StorageEvent.

Note: For a real world example, see Web Storage Demo. ^{check out the source code}

Listen to the storage event on dom/Window to catch changes in the storage. fiddle.

Cookies (web cookie, browser cookie) Cookies are data, stored in small text files as name-value pairs, on your computer.

JavaScript access using Document.cookie

New cookies can also be created via JavaScript using the Document.cookie property, and if the HttpOnly flag is not set, existing cookies can be accessed from JavaScript as well.

document.cookie = "yummy_cookie=choco"; 
document.cookie = "tasty_cookie=strawberry"; 
console.log(document.cookie); 
// logs "yummy_cookie=choco; tasty_cookie=strawberry"

Secure and HttpOnly cookies ^{HTTP State Management Mechanism}

Cookies are often used in web application to identify a user and their authenticated session

When receiving an HTTP request, a server can send a Set-Cookie header with the response. The cookie is usually stored by the browser, and then the cookie is sent with requests made to the same server inside a Cookie HTTP header.

Set-Cookie: <cookie-name>=<cookie-value> 
Set-Cookie: <cookie-name>=<cookie-value>; Expires=<date>

Session cookies will get removed when the client is shut down. They don't specify the Expires or Max-Age directives.

Set-Cookie: sessionid=38afes7a8; HttpOnly; Path=/

Permanent cookies expire at a specific date (Expires) or after a specific length of time (Max-Age).

Set-Cookie: id=a3fWa; Expires=Wed, 21 Oct 2015 07:28:00 GMT; Secure; HttpOnly

The Cookie HTTP request header contains stored HTTP cookies previously sent by the server with the Set-Cookie header. HTTP-only cookies aren't accessible via JavaScript through the Document.cookie property, the XMLHttpRequest and Request APIs to mitigate attacks against cross-site scripting (XSS).

Cookies are mainly used for three purposes:

• Session management « Logins, shopping carts, game scores, or anything else the server should remember
• Personalization « User preferences, themes, and other settings
• Tracking (Recording and analyzing user behavior) « Cookies have a domain associated to them. If this domain is the same as the domain of the page you are on, the cookies is said to be a first-party cookie. If the domain is different, it is said to be a third-party cookie. While first-party cookies are sent only to the server setting them, a web page may contain images or other components stored on servers in other domains (like ad banners). Cookies that are sent through these third-party components are called third-party cookies and are mainly used for advertising and tracking across the web.

Cookies were invented to solve the problem "how to remember information about the user":

• When a user visits a web page, his name can be stored in a cookie.
• Next time the user visits the page, cookies belonging to the page is added to the request. This way the server gets the necessary data to "remember" information about users.

GitHubGist Example

As summary,

• localStorage persists over different tabs or windows, and even if we close the browser, accordingly with the domain security policy and user choices about quota limit.
• sessionStorage object does not persist if we close the tab (top-level browsing context) as it does not exists if we surf via another tab or window.
• Web Storage (session, local) allows us to save a large amount of key/value pairs and lots of text, something impossible to do via cookie.
• Cookies that are used for sensitive actions should have a short lifetime only.
• Cookies mainly used for advertising and tracking across the web. See for example the types of cookies used by Google.
• Cookies are sent with every request, so they can worsen performance (especially for mobile data connections). Modern APIs for client storage are the Web storage API (localStorage and sessionStorage) and IndexedDB.

I also wanted this and came up with this solution (I'm only using the date part - a default time makes no sense as a PropertyGrid default):

public class DefaultDateAttribute : DefaultValueAttribute {
  public DefaultDateAttribute(short yearoffset)
    : base(DateTime.Now.AddYears(yearoffset).Date) {
  }
}

This just creates a new attribute that you can add to your DateTime property. E.g. if it defaults to DateTime.Now.Date:

[DefaultDate(0)]

GRANTs on different objects are separate. GRANTing on a database doesn't GRANT rights to the schema within. Similiarly, GRANTing on a schema doesn't grant rights on the tables within.

If you have rights to SELECT from a table, but not the right to see it in the schema that contains it then you can't access the table.

The rights tests are done in order:

Do you have `USAGE` on the schema? 
    No:  Reject access. 
    Yes: Do you also have the appropriate rights on the table? 
        No:  Reject access. 
        Yes: Check column privileges.

Your confusion may arise from the fact that the public schema has a default GRANT of all rights to the role public, which every user/group is a member of. So everyone already has usage on that schema.

The phrase:

(assuming that the objects' own privilege requirements are also met)

Is saying that you must have USAGE on a schema to use objects within it, but having USAGE on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.

It's like a directory tree. If you create a directory somedir with file somefile within it then set it so that only your own user can access the directory or the file (mode rwx------ on the dir, mode rw------- on the file) then nobody else can list the directory to see that the file exists.

If you were to grant world-read rights on the file (mode rw-r--r--) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.

If you instead set rwx-r-xr-x on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.

You need to set both permissions for people to actually be able to view the file.

Same thing in Pg. You need both schema USAGE rights and object rights to perform an action on an object, like SELECT from a table.

(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECTing from pg_class directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)

You're trying to concatenate a string and an integer, which is incorrect.

Change print(numlist.pop(2)+" has been removed") to any of these:

Explicit int to str conversion:

print(str(numlist.pop(2)) + " has been removed")

Use , instead of +:

print(numlist.pop(2), "has been removed")

String formatting:

print("{} has been removed".format(numlist.pop(2)))

Here is another modification of the most popular answer, but with handling of variable length of text in the first column labels: http://jsfiddle.net/ozx56n41/

Basically, I'm using the second column for creating row height, like was mentioned. But my fiddle actually works unlike most mentioned above.

public abstract class SingleFragmentActivity extends Activity {

    public static final String FRAGMENT_TAG = "single";
    private Fragment fragment;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
        if (savedInstanceState == null) {
            fragment = onCreateFragment();
           getFragmentManager().beginTransaction()
                   .add(android.R.id.content, fragment, FRAGMENT_TAG)
                   .commit();
       } else {
           fragment = getFragmentManager().findFragmentByTag(FRAGMENT_TAG);
       }
   }

   public abstract Fragment onCreateFragment();

   public Fragment getFragment() {
       return fragment;
   }

use

public class ViewCatalogItemActivity extends SingleFragmentActivity {
    @Override
    public Fragment onCreateFragment() {
        return new FragmentWorkShops();
    }

}

See this. Your code would be something like the following:

from django.db.models import Max
# Generates a "SELECT MAX..." query
Argument.objects.aggregate(Max('rating')) # {'rating__max': 5}

You can also use this on existing querysets:

from django.db.models import Max
args = Argument.objects.filter(name='foo') # or whatever arbitrary queryset
args.aggregate(Max('rating')) # {'rating__max': 5}

If you need the model instance that contains this max value, then the code you posted is probably the best way to do it:

arg = args.order_by('-rating')[0]

Note that this will error if the queryset is empty, i.e. if no arguments match the query (because the [0] part will raise an IndexError). If you want to avoid that behavior and instead simply return None in that case, use .first():

arg = args.order_by('-rating').first() # may return None

Just use <c:url>-tag with an application context relative path.

When the value parameter starts with an /, then the tag will treat it as an application relative url, and will add the application-name to the url. Example:

jsp:

<c:url value="/templates/style/main.css" var="mainCssUrl" />`
<link rel="stylesheet" href="${mainCssUrl}" />
...
<c:url value="/home" var="homeUrl" />`
<a href="${homeUrl}">home link</a>

will become this html, with an domain relative url:

<link rel="stylesheet" href="/AppName/templates/style/main.css" />
...
<a href="/AppName/home">home link</a>

The XPath spec. defines the string value of an element as the concatenation (in document order) of all of its text-node descendents.

This explains the "strange results".

"Better" results can be obtained using the expressions below:

//*[text() = 'qwerty']

The above selects every element in the document that has at least one text-node child with value 'qwerty'.

//*[text() = 'qwerty' and not(text()[2])]

The above selects every element in the document that has only one text-node child and its value is: 'qwerty'.

python -m pip install opencv-python

which will install opencv based on your current python

To explain it clear:

If you don't like it like this:

add %matplotlib inline

and there you have it in your jupyter notebook.

A simple answer:

objArray.sort(function(obj1, obj2) {
   return obj1.DepartmentName > obj2.DepartmentName;
});

ES6 way:

objArray.sort((obj1, obj2) => {return obj1.DepartmentName > obj2.DepartmentName};

If you need to make it lowercase/uppercase etc, just do that and store that result in a variable than compare that variable. Example:

objArray.sort((obj1, obj2) => {
   var firstObj = obj1.toLowerCase();
   var secondObj = obj2.toLowerCase();
   return firstObj.DepartmentName > secondObj.DepartmentName;
});

To get this to work with pyenv on Ubuntu 16.04, I had to:

$ sudo apt-get install python-tk python3-tk tk-dev

Then install the version of Python I wanted via pyenv:

$ pyenv install 3.6.2

Then I could import tkinter just fine:

import tkinter

Here is how you set the date and time:

update user set expiry_date=TO_DATE('31/DEC/2017 12:59:59', 'dd/mm/yyyy hh24:mi:ss') where id=123;

In powershell 2.0

split-path $pwd

I've never seen any practical use of this, but you should probably consider DOM stylesheets. However, I honestly think that's overkill.

If you simply want to get the width and height of an element, irrespective of where the dimensions are being applied from, just use element.offsetWidth and element.offsetHeight.

A more proper way of doing this with requests would be:

import requests

payload = {'username': 'bob', 'email': '[email protected]'}

try:
    response = requests.put(url="http://somedomain.org/endpoint", data=payload)
    response.raise_for_status()
except requests.exceptions.RequestException as e:
    print(e)
    raise

This raises an exception if there is an error in the HTTP PUT request.

Yes! You can use the new Visual Studio for Mac, which Microsoft launched in November.

I noted that you asked for a solution that does not rely on finish(), but I wonder if this may help nonetheless.

I tracked whether an exit flag is raised with a static class variable, which survives the entire app lifespan. In each relevant activity's onResume(), use

@Override
public void onResume() {
    super.onResume();
    if (ExitHelper.isExitFlagRaised) {
        this.finish();
    }
}

The ExitHelper class

public class ExitHelper {
    public static boolean isExitFlagRaised = false;
}

Let's say in mainActivity, a user presses a button to exit - you can set ExitHelper.isExitFlagRaised = true; and then finish(). Thereafter, other relevant activities that are resumed automatically will be finished as well.

You can write a generic filterByIndex() function and make use of type inference in TS to save the hassle with the callback function:

let's say you have your array [1,2,3,4] that you want to filter() with the indices specified in the [2,4] array.

var filtered = [1,2,3,4,].filter(byIndex(element => element, [2,4]))

the byIndex function expects the element function and an array and looks like this:

byIndex = (getter: (e:number) => number, arr: number[]) => (x: number) => {
    var i = getter(x);
    return arr.indexOf(i); 
}

result is then

filtered = [1,3]

How about this... It only requires one iteration over the string (doesn't use strlen, which iterates over the string). When the function returns you get a pointer to the start of the trimmed string which is null terminated. The string is trimmed of spaces from the left (until the first character is found). The string is also trimmed of all trailing spaces after the last nonspace character.

char* trim(char* input) {
    char* start = input;
    while (isSpace(*start)) { //trim left
        start++;
    }

    char* ptr = start;
    char* end = start;
    while (*ptr++ != '\0') { //trim right
        if (!isSpace(*ptr)) { //only move end pointer if char isn't a space
            end = ptr;
        }
    }

    *end = '\0'; //terminate the trimmed string with a null
    return start;
}

bool isSpace(char c) {
    switch (c) {
        case ' ':
        case '\n':
        case '\t':
        case '\f':
        case '\r':
            return true;
            break;
        default:
            return false;
            break;
    }
}

I get the following when I try it:

>> Date.today.to_time.to_i
=> 1259244000
>> Time.now.to_i
=> 1259275709

The difference between these two numbers is due to the fact that Date does not store the hours, minutes or seconds of the current time. Converting a Date to a Time will result in that day, midnight.

just return true inside your if statement

var myArr = [1,2,3,4];

myArr.forEach(function(elem){
  if (elem === 3) {

      return true;

    // Go to "next" iteration. Or "continue" to next iteration...
  }

  console.log(elem);
});

I usually use numpy sum over the logical condition column:

>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame({'Age' : [20,24,18,5,78]})
>>> np.sum(df['Age'] > 20)
2

This seems to me slightly shorter than the solution presented above

You are trying to link objects compiled by different versions of the compiler. That's not supported in modern versions of VS, at least not if you are using the C++ standard library. Different versions of the standard library are binary incompatible and so you need all the inputs to the linker to be compiled with the same version. Make sure you re-compile all the objects that are to be linked.

The compiler error names the objects involved so the information the the question already has the answer you are looking for. Specifically it seems that the static library that you are linking needs to be re-compiled.

So the solution is to recompile Projectname1.lib with VS2012.

What i use to do, is put those multiple values in an array like

var options = [foo, bar];

and then, use indexOf()

if(options.indexOf(foobar) > -1){
   //do something
}

for prettiness:

if([foo, bar].indexOf(foobar) +1){
   //you can't get any more pretty than this :)
}

and for the older browsers:
( https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/IndexOf )

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function (searchElement /*, fromIndex */ ) {
        "use strict";
        if (this == null) {
            throw new TypeError();
        }
        var t = Object(this);
        var len = t.length >>> 0;
        if (len === 0) {
            return -1;
        }
        var n = 0;
        if (arguments.length > 0) {
            n = Number(arguments[1]);
            if (n != n) { // shortcut for verifying if it's NaN
                n = 0;
            } else if (n != 0 && n != Infinity && n != -Infinity) {
                n = (n > 0 || -1) * Math.floor(Math.abs(n));
            }
        }
        if (n >= len) {
            return -1;
        }
        var k = n >= 0 ? n : Math.max(len - Math.abs(n), 0);
        for (; k < len; k++) {
            if (k in t && t[k] === searchElement) {
                return k;
            }
        }
        return -1;
    }
}

Import this in to app.module.ts

import {HttpClientModule} from '@angular/common/http';

and add this one in imports

HttpClientModule

I think this is what your looking for:

    var objs= (from c in List_Objects 
orderby c.TypeID  select c).GroupBy(g=>g.TypeID).Select(x=>x.FirstOrDefault());

Looking more closely at my web.config set up, one of the comments in this post is very helpful

in asp.net 3.5 sp1 there is a new parameter redirectMode

So we can amend customErrors to add this parameter:

<customErrors mode="RemoteOnly" defaultRedirect="~/errors/GeneralError.aspx" redirectMode="ResponseRewrite" />

the ResponseRewrite mode allows us to load the «Error Page» without redirecting the browser, so the URL stays the same, and importantly for me, exception information is not lost.

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

The simplest way is to use the Common Table Expression (CTE) introduced in SQL 2005

with cte as
(select u.assid col1 ,s.assid col2 from ud u inner join sale s on u.id = s.udid)
update cte set col1=col2

do you want to try the below code I found on the internet somewhere many moons ago and used.

It uses the Export function of the Chart object along with the CopyPicture method of the Range object.

References:

• MSDN - Export method as it applies to the Chart object. to save the clipboard as an Image

• MSDN - CopyPicture method as it applies to the Range object to copy the range as a picture

  dim sSheetName as string
  dim oRangeToCopy as range
  Dim oCht As Chart
  
  sSheetName ="Sheet1" ' worksheet to work on
  set  oRangeToCopy =Range("B2:H8") ' range to be copied
  
  Worksheets(sSheetName).Range(oRangeToCopy).CopyPicture xlScreen, xlBitmap
  set oCht =charts.add
  
  with oCht
      .paste
      .Export FileName:="C:\SavedRange.jpg", Filtername:="JPG"
  end with
  

You can avoid making a copy of the object using Wen's solution and inplace=True:

df.fillna({'a':0, 'b':0}, inplace=True)
print(df)

Which yields:

     a    b    c
0  1.0  4.0  NaN
1  2.0  5.0  NaN
2  3.0  0.0  7.0
3  0.0  6.0  8.0

The following steps are to reset the password for a user in case you forgot, this would also solve your mentioned error.

First, stop your MySQL:

sudo /etc/init.d/mysql stop

Now start up MySQL in safe mode and skip the privileges table:

sudo mysqld_safe --skip-grant-tables &

Login with root:

mysql -uroot

And assign the DB that needs to be used:

use mysql;

Now all you have to do is reset your root password of the MySQL user and restart the MySQL service:

update user set password=PASSWORD("YOURPASSWORDHERE") where User='root';

flush privileges;

quit and restart MySQL:

quit

sudo /etc/init.d/mysql stop sudo /etc/init.d/mysql start Now your root password should be working with the one you just set, check it with:

mysql -u root -p

To add to Blender's answer, you can disable SSL certificate validation for all requests using Session.verify = False

import requests

session = requests.Session()
session.verify = False
session.post(url='https://example.com', data={'bar':'baz'})

Note that urllib3, (which Requests uses), strongly discourages making unverified HTTPS requests and will raise an InsecureRequestWarning.

When I was started with express always wanted a solution to use import instead require

const express = require("express");
// to 
import express from "express"

Many time go through this line:- Unfortunately, Node.js doesn't support ES6's import yet.

Now to help other I create new two solutions here

1) esm:-

The brilliantly simple, babel-less, bundle-less ECMAScript module loader. let's make it work

  yarn add esm / npm install esm

create start.js or use your namespace

 require = require("esm")(module/*, options*/)
 // Import the rest of our application.
 module.exports = require('./src/server.js')
 // where server.js is express server start file

Change in your package.josn pass path of start.js

  "scripts": {
    "start": "node start.js",
    "start:dev": "nodemon start.js",
  },
  "dependencies": {
+    "esm": "^3.2.25",
  },
  "devDependencies": {
+   "nodemon": "^1.19.2"
  }

2) Babel js:-

This can be divide into 2 part

a) Solution 1 thanks to timonweb.com

b) Solution 2

use Babel 6 (older version of babel-preset-stage-3 ^6.0) create .babelrc file at your root folder

{
    "presets": ["env", "stage-3"]
}

Install babel-preset-stage-3

yarn add babel-cli babel-polyfill babel-preset-env bable-preset-stage-3 nodemon --dev

Change in package.json

"scripts": {
+   "start:dev": "nodemon --exec babel-node -- ./src/index.js",
+   "start": "npm run build && node ./build/index.js",
+   "build": "npm run clean && babel src -d build -s --source-maps --copy-files",
+   "clean": "rm -rf build && mkdir build"
},
"devDependencies": {
+    "babel-cli": "^6.26.0",
+    "babel-polyfill": "^6.26.0",
+    "babel-preset-env": "^1.7.0",
+    "babel-preset-stage-3": "^6.24.1",
+    "nodemon": "^1.19.4"
},

Start your server

yarn start / npm start

Oooh no we create new problem

regeneratorRuntime.mark(function _callee(email, password) {
^
ReferenceError: regeneratorRuntime is not defined

This error only come when you use async/await in your code. Then use polyfill that includes a custom regenerator runtime and core-js. add on top of index.js

import "babel-polyfill"

This allow you to use async/await

use Babel 7

Need to upto date every thing in your project let start with babel 7 .babelrc

{
  "presets": ["@babel/preset-env"]
}

Some change in package.json

"scripts": {
+  "start:dev": "nodemon --exec babel-node -- ./src/index.js",
+  "start": "npm run build && node ./build/index.js",
+  "build": "npm run clean && babel src -d build -s --source-maps --copy-files",
+  "clean": "rm -rf build && mkdir build",
    ....
}
"devDependencies": {
+   "@babel/cli": "^7.0.0",
+   "@babel/core": "^7.6.4",
+   "@babel/node": "^7.0.0",
+   "@babel/polyfill": "^7.0.0",
+   "@babel/preset-env": "^7.0.0",
+   "nodemon": "^1.19.4"
....
}

and use import "@babel/polyfill" on start point

import "@babel/polyfill"
import express from 'express'
const app = express()

//GET request
app.get('/', async (req, res) {
  // await operation
  res.send('hello world')
})
app.listen(4000, () => console.log(' Server listening on port 400!'))

Are you thinking why start:dev

Seriously. It is good question if you are new. Every change you are boar with start server every time then use yarn start:dev as development server every change restart server automatically for more on nodemon

If you are using PHP you can use this, and I'm sure it's almost similar in other languages as well

$WebsiteURL = "https://api.telegram.org/bot".$BotToken;
$text = "<b>This</b> <i>is some Text</i>";
$Update = file_get_contents($WebsiteURL."/sendMessage?chat_id=$chat_id&text=$text&parse_mode=html);

echo $Update;

Here is the list of all tags that you can use

<b>bold</b>, <strong>bold</strong>
<i>italic</i>, <em>italic</em>
<a href="http://www.example.com/">inline URL</a>
<code>inline fixed-width code</code>
<pre>pre-formatted fixed-width code block</pre>

http://keycodes.atjayjo.com/

This app is just awesome. It is essentially a virtual keyboard that immediately shows you the keycode pressed on a standard US keyboard.

Actually, you can achieve this pretty easy. Simply specify the line height as a number:

<p style="line-height:1.5">
    <span style="font-size:12pt">The quick brown fox jumps over the lazy dog.</span><br />
    <span style="font-size:24pt">The quick brown fox jumps over the lazy dog.</span>
</p>

The difference between number and percentage in the context of the line-height CSS property is that the number value is inherited by the descendant elements, but the percentage value is first computed for the current element using its font size and then this computed value is inherited by the descendant elements.

For more information about the line-height property, which indeed is far more complex than it looks like at first glance, I recommend you take a look at this online presentation.

If you are referring to the System.Net.HttpClient in .NET 4.5, you can get the content returned by GetAsync using the HttpResponseMessage.Content property as an HttpContent-derived object. You can then read the contents to a string using the HttpContent.ReadAsStringAsync method or as a stream using the ReadAsStreamAsync method.

The HttpClient class documentation includes this example:

  HttpClient client = new HttpClient();
  HttpResponseMessage response = await client.GetAsync("http://www.contoso.com/");
  response.EnsureSuccessStatusCode();
  string responseBody = await response.Content.ReadAsStringAsync();

To remove spaces... please use LTRIM/RTRIM

 LTRIM(String)
 RTRIM(String)

The String parameter that is passed to the functions can be a column name, a variable, a literal string or the output of a user defined function or scalar query.

SELECT LTRIM(' spaces at start')
SELECT RTRIM(FirstName) FROM Customers

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

The accepted answer did not take into account single digit returned hexadecimal codes. This is easily adjusted by:

function numHex(s)
{
    var a = s.toString(16);
    if ((a.length % 2) > 0) {
        a = "0" + a;
    }
    return a;
}

and

function strHex(s)
{
    var a = "";
    for (var i=0; i<s.length; i++) {
        a = a + numHex(s.charCodeAt(i));
    }

    return a;
}

I believe the above answers have been posted numerous times by others in one form or another. I wrap these in a toHex() function like so:

function toHex(s)
{
    var re = new RegExp(/^\s*(\+|-)?((\d+(\.\d+)?)|(\.\d+))\s*$/);

    if (re.test(s)) {
        return '#' + strHex( s.toString());
    }
    else {
        return 'A' + strHex(s);
    }
}

Note that the numeric regular expression came from 10+ Useful JavaScript Regular Expression Functions to improve your web applications efficiency.

Update: After testing this thing several times I found an error (double quotes in the RegExp), so I fixed that. HOWEVER! After quite a bit of testing and having read the post by almaz - I realized I could not get negative numbers to work.

Further - I did some reading up on this and since all JavaScript numbers are stored as 64 bit words no matter what - I tried modifying the numHex code to get the 64 bit word. But it turns out you can not do that. If you put "3.14159265" AS A NUMBER into a variable - all you will be able to get is the "3", because the fractional portion is only accessible by multiplying the number by ten(IE:10.0) repeatedly. Or to put that another way - the hexadecimal value of 0xF causes the floating point value to be translated into an integer before it is ANDed which removes everything behind the period. Rather than taking the value as a whole (i.e.: 3.14159265) and ANDing the floating point value against the 0xF value.

So the best thing to do, in this case, is to convert the 3.14159265 into a string and then just convert the string. Because of the above, it also makes it easy to convert negative numbers because the minus sign just becomes 0x26 on the front of the value.

So what I did was on determining that the variable contains a number - just convert it to a string and convert the string. This means to everyone that on the server side you will need to unhex the incoming string and then to determine the incoming information is numeric. You can do that easily by just adding a "#" to the front of numbers and "A" to the front of a character string coming back. See the toHex() function.

Have fun!

After another year and a lot of thinking, I decided that the "toHex" function (and I also have a "fromHex" function) really needed to be revamped. The whole question was "How can I do this more efficiently?" I decided that a to/from hexadecimal function should not care if something is a fractional part but at the same time it should ensure that fractional parts are included in the string.

So then the question became, "How do you know you are working with a hexadecimal string?". The answer is simple. Use the standard pre-string information that is already recognized around the world.

In other words - use "0x". So now my toHex function looks to see if that is already there and if it is - it just returns the string that was sent to it. Otherwise, it converts the string, number, whatever. Here is the revised toHex function:

/////////////////////////////////////////////////////////////////////////////
//  toHex().  Convert an ASCII string to hexadecimal.
/////////////////////////////////////////////////////////////////////////////
toHex(s)
{
    if (s.substr(0,2).toLowerCase() == "0x") {
        return s;
    }

    var l = "0123456789ABCDEF";
    var o = "";

    if (typeof s != "string") {
        s = s.toString();
    }
    for (var i=0; i<s.length; i++) {
        var c = s.charCodeAt(i);

        o = o + l.substr((c>>4),1) + l.substr((c & 0x0f),1);
    }

    return "0x" + o;
}

This is a very fast function that takes into account single digits, floating point numbers, and even checks to see if the person is sending a hex value over to be hexed again. It only uses four function calls and only two of those are in the loop. To un-hex the values you use:

/////////////////////////////////////////////////////////////////////////////
//  fromHex().  Convert a hex string to ASCII text.
/////////////////////////////////////////////////////////////////////////////
fromHex(s)
{
    var start = 0;
    var o = "";

    if (s.substr(0,2).toLowerCase() == "0x") {
        start = 2;
    }

    if (typeof s != "string") {
        s = s.toString();
    }
    for (var i=start; i<s.length; i+=2) {
        var c = s.substr(i, 2);

        o = o + String.fromCharCode(parseInt(c, 16));
    }

    return o;
}

Like the toHex() function, the fromHex() function first looks for the "0x" and then it translates the incoming information into a string if it isn't already a string. I don't know how it wouldn't be a string - but just in case - I check. The function then goes through, grabbing two characters and translating those in to ASCII characters. If you want it to translate Unicode, you will need to change the loop to going by four(4) characters at a time. But then you also need to ensure that the string is NOT divisible by four. If it is - then it is a standard hexadecimal string. (Remember the string has "0x" on the front of it.)

A simple test script to show that -3.14159265, when converted to a string, is still -3.14159265.

<?php

    echo <<<EOD
<html>
    <head><title>Test</title>
        <script>
            var a = -3.14159265;
            alert( "A = " + a );
            var b = a.toString();
            alert( "B = " + b );
        </script>
    </head>
    <body>
    </body>
</html>
EOD;

?>

Because of how JavaScript works in respect to the toString() function, all of those problems can be eliminated which before were causing problems. Now all strings and numbers can be converted easily. Further, such things as objects will cause an error to be generated by JavaScript itself. I believe this is about as good as it gets. The only improvement left is for W3C to just include a toHex() and fromHex() function in JavaScript.

Use

// aspect-type.js
class AspectType {

}

export default AspectType;

Then to import it

// some-other-file.js
import AspectType from './aspect-type';

Read http://babeljs.io/docs/learn-es2015/#modules for more details

Your concatenation syntax is correct.

Most likely the callback function isn't even being called. You can test that by putting an alert(), console.log() or debugger line in that function.

If it isn't being called, most likely there's an AJAX error. Look at chaining a .fail() handler after $.post() to find out what the error is, e.g.:

$.post('ajaxskeleton.php', {
    red: text       
}, function(){
    $('#part' + number).html(text);
}).fail(function(jqXHR, textStatus, errorThrown) {
    console.log(arguments);
});

I've found this to work very well. It uses the .range property of the .autofilter object, which seems to be a rather obscure, but very handy, feature:

Sub copyfiltered()
    ' Copies the visible columns
    ' and the selected rows in an autofilter
    '
    ' Assumes that the filter was previously applied
    '
    Dim wsIn As Worksheet
    Dim wsOut As Worksheet

    Set wsIn = Worksheets("Sheet1")
    Set wsOut = Worksheets("Sheet2")

    ' Hide the columns you don't want to copy
    wsIn.Range("B:B,D:D").EntireColumn.Hidden = True

    'Copy the filtered rows from wsIn and and paste in wsOut
    wsIn.AutoFilter.Range.Copy Destination:=wsOut.Range("A1")
End Sub

Import paths are relative to your $GOPATH and $GOROOT environment variables. For example, with the following $GOPATH:

GOPATH=/home/me/go

Packages located in /home/me/go/src/lib/common and /home/me/go/src/lib/routers are imported respectively as:

import (
    "lib/common"
    "lib/routers"
)

Thanks to AddRange:

Example:

public class Person
{ 
    private string Name;
    private string FirstName;

    public Person(string name, string firstname) => (Name, FirstName) = (name, firstname);
}

To add multiple Person to a List<>:

List<Person> listofPersons = new List<Person>();
listofPersons.AddRange(new List<Person>
{
    new Person("John1", "Doe" ),
    new Person("John2", "Doe" ),
    new Person("John3", "Doe" ),
 });

To create a patch with both modified & new files (staged) you can run:

git diff HEAD > file_name.patch

I got this from using the Anaconda default environment instead of my custom one with pandas installed.

Changing to the right environment and reopening the Jupyter notebooks did not fix this for me (python 3.7, pandas 0.23.0). Restarting Anaconda did.

border-style:solid; will override the inset style. Which is what you asked.

border:none will remove the border all together.

border-width:1px will set it up to be kind of like before the background change.

border:1px solid #cccccc is more specific and applies all three, width, style and color.

Example: https://jsbin.com/quleh/2/edit?html,output

There is a typo error :

$('#activelist :checkbox')...

Should be :

$('#inactivelist:checkbox')...

This is a simple way to do it without any triggers or sequences:

insert into WORKQUEUE (ID, facilitycode, workaction, description)
  values ((select max(ID)+1 from WORKQUEUE), 'J', 'II', 'TESTVALUES')

It worked for me but would not work with an empty table, I guess.

Month start from 0. 0 = January, 1 = February, 2 = March, ..., 11 = December.

There is a CocoaPods to facilitate the observation on NSNotificationCentr for the keyboard's visibility here: https://github.com/levantAJ/Keyhi

pod 'Keyhi'

If you really need this you can achieve your goal with help of separate table for sequencing (if you don't mind) and a trigger.

Tables

CREATE TABLE table1_seq
(
  id INT NOT NULL AUTO_INCREMENT PRIMARY KEY
);
CREATE TABLE table1
(
  id VARCHAR(7) NOT NULL PRIMARY KEY DEFAULT '0', name VARCHAR(30)
);

Now the trigger

DELIMITER $$
CREATE TRIGGER tg_table1_insert
BEFORE INSERT ON table1
FOR EACH ROW
BEGIN
  INSERT INTO table1_seq VALUES (NULL);
  SET NEW.id = CONCAT('LHPL', LPAD(LAST_INSERT_ID(), 3, '0'));
END$$
DELIMITER ;

Then you just insert rows to table1

INSERT INTO Table1 (name) 
VALUES ('Jhon'), ('Mark');

And you'll have

|      ID | NAME |
------------------
| LHPL001 | Jhon |

I have used transform to correct the offset. It works great with round icons like the life ring.

<span class="fa fa-life-ring"></span>

.fa {
    transform: translateY(-4%);
}

If you organize your test cases, that is, follow the same organization like the actual code and also use relative imports for modules in the same package, you can also use the following command format:

python -m unittest mypkg.tests.test_module.TestClass.test_method

# In your case, this would be:
python -m unittest testMyCase.MyCase.testItIsHot

Python 3 documentation for this: Command-Line Interface

If you just want to see if it's present, try turning the list into a dict:

# Generate a list
l = [n*n for n in range(1000)]

# Convert to dict - doesn't matter what you map values to
d = dict((x, 1) for x in l)

count = 0
for n in range(1000000):
    # Compare with "if n in l"
    if n in d:
        count += 1

On my machine, "if n in l" took 37 seconds, while "if n in d" took 0.4 seconds.

I create a simple function with typescript

const diffDuration: moment.Duration = moment.duration(moment('2017-09-04 12:55').diff(moment('2017-09-02 13:26')));
setDiffTimeString(diffDuration);

function setDiffTimeString(diffDuration: moment.Duration) {
  const str = [];
  diffDuration.years() > 0 ? str.push(`${diffDuration.years()} year(s)`) : null;
  diffDuration.months() > 0 ? str.push(`${diffDuration.months()} month(s)`) : null;
  diffDuration.days() > 0 ? str.push(`${diffDuration.days()} day(s)`) : null;
  diffDuration.hours() > 0 ? str.push(`${diffDuration.hours()} hour(s)`) : null;
  diffDuration.minutes() > 0 ? str.push(`${diffDuration.minutes()} minute(s)`) : null;
  console.log(str.join(', '));
} 
// output: 1 day(s), 23 hour(s), 29 minute(s)

for generate javascript https://www.typescriptlang.org/play/index.html

e= StringVar()
def fileDialog():
    filename = filedialog.askopenfilename(initialdir = "/",title = "Select A 
    File",filetype = (("jpeg","*.jpg"),("png","*.png"),("All Files","*.*")))
    e.set(filename)
la = Entry(self,textvariable = e,width = 30).place(x=230,y=330)
butt=Button(self,text="Browse",width=7,command=fileDialog).place(x=430,y=328)

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

In my opinion the best option is to use react-native-config. It supports 12 factor.

I found this package extremely useful. You can set multiple environments, e.g. development, staging, production.

In case of Android, variables are available also in Java classes, gradle, AndroidManifest.xml etc. In case of iOS, variables are available also in Obj-C classes, Info.plist.

You just create files like

• .env.development
• .env.staging
• .env.production

You fill these files with key, values like

API_URL=https://myapi.com
GOOGLE_MAPS_API_KEY=abcdefgh

and then just use it:

import Config from 'react-native-config'

Config.API_URL  // 'https://myapi.com'
Config.GOOGLE_MAPS_API_KEY  // 'abcdefgh'

If you want to use different environments, you basically set ENVFILE variable like this:

ENVFILE=.env.staging react-native run-android

or for assembling app for production (android in my case):

cd android && ENVFILE=.env.production ./gradlew assembleRelease

Now it's pretty easy to implement for RecyclerView with ItemTouchHelper. Just override onMove method from ItemTouchHelper.Callback:

 @Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
    mMovieAdapter.swap(viewHolder.getAdapterPosition(), target.getAdapterPosition());
    return true;
}

Pretty good tutorial on this can be found at medium.com : Drag and Swipe with RecyclerView

Holla/Hello, I got it! You can easily get the file name,tmp_name,file_size etc.So I will show you how to get file name with a line of code.

for ($i = 0 ; $i < count($files['name']); $i++) {
    echo $files['name'][$i].'<br/>';
}

It is tested on my PC.

Test it

import java.util.Scanner;
public class BinaryToDecimal{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);
    int binaryNumber = 0;
    int counter = 0;
    int number = 0;


    System.out.print("Input binary number: ");
    binaryNumber = input.nextInt();

    //it's going to stop when the binaryNumber/10 is less than 0
    //example:
    //binaryNumber = 11/10. The result value is 1 when you do the next
    //operation 1/10 . The result value is 0     

    while(binaryNumber != 0)
    {
        //Obtaining the remainder of the division and multiplying it 
        //with the number raised to two

        //adding it up with the previous result

        number += ((binaryNumber % 10)) * Math.pow(2,counter);

        binaryNumber /= 10;  //removing one digit from the binary number

        //Increasing counter 2^0, 2^1, 2^2, 2^3.....
        counter++;

    }
    System.out.println("Decimal number : " + number);


}

}

Another option is to check if it's busy with a timer:

Set the timer as disabled by default. Then whenever navigating, enable it. i.e.:

WebBrowser1.Navigate("https://www.somesite.com")
tmrBusy.Enabled = True

And the timer:

    Private Sub tmrBusy_Tick(sender As Object, e As EventArgs) Handles tmrBusy.Tick

        If WebBrowser1.IsBusy = True Then

            Debug.WriteLine("WB Busy ...")

        Else

            Debug.WriteLine("WB Done.")
            tmrBusy.Enabled = False

        End If

    End Sub

WTF?! My cronjob doesn't run?!

Here's a checklist guide to debug not running cronjobs:

1. Is the Cron daemon running?

• Run ps ax | grep cron and look for cron.
• Debian: service cron start or service cron restart

2. Is cron working?

• * * * * * /bin/echo "cron works" >> /tmp/file
• Syntax correct? See below.
• You obviously need to have write access to the file you are redirecting the output to. A unique file name in /tmp which does not currently exist should always be writable.
• Probably also add 2>&1 to include standard error as well as standard output, or separately output standard error to another file with 2>>/tmp/errors

3. Is the command working standalone?

• Check if the script has an error, by doing a dry run on the CLI
• When testing your command, test as the user whose crontab you are editing, which might not be your login or root

4. Can cron run your job?

• Check /var/log/cron.log or /var/log/messages for errors.
• Ubuntu: grep CRON /var/log/syslog
• Redhat: /var/log/cron

5. Check permissions

• Set executable flag on the command: chmod +x /var/www/app/cron/do-stuff.php
• If you redirect the output of your command to a file, verify you have permission to write to that file/directory

6. Check paths

• check she-bangs / hashbangs line
• do not rely on environment variables like PATH, as their value will likely not be the same under cron as under an interactive session

7. Don't suppress output while debugging

• Commonly used is this suppression: 30 1 * * * command > /dev/null 2>&1
• Re-enable the standard output or standard error message output by removing >/dev/null 2>&1 altogether; or perhaps redirect to a file in a location where you have write access: >>cron.out 2>&1 will append standard output and standard error to cron.out in the invoking user's home directory.
• If you are trying to figure out why something failed, the error messages will be visible in this file. Read it and understand it.

Still not working? Yikes!

1. Raise the cron debug level

• Debian
  • in /etc/default/cron
  • set EXTRA_OPTS="-L 2"
  • service cron restart
  • tail -f /var/log/syslog to see the scripts executed
• Ubuntu
  • in /etc/rsyslog.d/50-default.conf
  • add or comment out line cron.crit /var/log/cron.log
  • reload logger sudo /etc/init.d/rsyslog reload
  • re-run cron
  • open /var/log/cron.log and look for detailed error output
• Reminder: deactivate log level, when you are done with debugging

2. Run cron and check log files again

Cronjob Syntax

# Minute  Hour  Day of Month      Month         Day of Week    User Command    
# (0-59) (0-23)   (1-31)    (1-12 or Jan-Dec) (0-6 or Sun-Sat)  
         
    0       2       *             *                *          root /usr/bin/find

This syntax is only correct for the root user. Regular user crontab syntax doesn't have the User field (regular users aren't allowed to run code as any other user);

# Minute  Hour  Day of Month      Month         Day of Week    Command    
# (0-59) (0-23)   (1-31)    (1-12 or Jan-Dec) (0-6 or Sun-Sat)  
         
    0       2       *             *                *          /usr/bin/find

Crontab Commands

1. crontab -l
   • Lists all the user's cron tasks.
2. crontab -e, for a specific user: crontab -e -u agentsmith
   • Starts edit session of your crontab file.
   • When you exit the editor, the modified crontab is installed automatically.
3. crontab -r
   • Removes your crontab entry from the cron spooler, but not from crontab file.

When using Netbean, go under project tab and click the dropdown button there to select Libraries folder. Right Click on d Library folder and select 'Add JAR/Folder'. Locate the mysql-connectore-java.*.jar file where u have it on ur system. This worked for me and I hope it does for u too. Revert if u encounter any problem

In TSQL, the modulo is done with a percent sign.

SELECT 38 % 5 would give you the modulo 3

Boostrap 3 has a component for exactly this. It's:

<span class="badge">100</span>

Another solution

Here is a new solution based on Bennett McElwee answer in the same question as mentioned below.

Tested with IE 9 & 10, Opera 12.01, Google Chrome 22 and Firefox 15.0.
jsFiddle example

1.) Add this CSS to your site:

@media screen {
  #printSection {
      display: none;
  }
}

@media print {
  body * {
    visibility:hidden;
  }
  #printSection, #printSection * {
    visibility:visible;
  }
  #printSection {
    position:absolute;
    left:0;
    top:0;
  }
}

2.) Add my JavaScript function

function printElement(elem, append, delimiter) {
    var domClone = elem.cloneNode(true);

    var $printSection = document.getElementById("printSection");

    if (!$printSection) {
        $printSection = document.createElement("div");
        $printSection.id = "printSection";
        document.body.appendChild($printSection);
    }

    if (append !== true) {
        $printSection.innerHTML = "";
    }

    else if (append === true) {
        if (typeof (delimiter) === "string") {
            $printSection.innerHTML += delimiter;
        }
        else if (typeof (delimiter) === "object") {
            $printSection.appendChild(delimiter);
        }
    }

    $printSection.appendChild(domClone);
}?

You're ready to print any element on your site!
Just call printElement() with your element(s) and execute window.print() when you're finished.

Note: If you want to modify the content before it is printed (and only in the print version), checkout this example (provided by waspina in the comments): http://jsfiddle.net/95ezN/121/

One could also use CSS in order to show the additional content in the print version (and only there).

Former solution

I think, you have to hide all other parts of the site via CSS.

It would be the best, to move all non-printable content into a separate DIV:

<body>
  <div class="non-printable">
    <!-- ... -->
  </div>

  <div class="printable">
    <!-- Modal dialog comes here -->
  </div>
</body>

And then in your CSS:

.printable { display: none; }

@media print
{
    .non-printable { display: none; }
    .printable { display: block; }
}

Credits go to Greg who has already answered a similar question: Print <div id="printarea"></div> only?

There is one problem in using JavaScript: the user cannot see a preview - at least in Internet Explorer!

I had a similar problem and after going over a lot on stack overflow and spending time on the jar dependencies, I figured out that in my case, I had two sets of asm.jar. I removed one of them and it worked fine...

Use this CSS:

background: url('img.png') no-repeat; 
background-size: 100%;

In ES6, use Array.from:

function foo()
  {
  foo.bar = Array.from(arguments);
  foo.baz = foo.bar.join();
  }

foo(1,2,3,4,5,6,7);
foo.bar // Array [1, 2, 3, 4, 5, 6, 7]
foo.baz // "1,2,3,4,5,6,7"

function foo()
  {
  foo.bar = JSON.stringify(arguments); 
  foo.baz = JSON.parse(foo.bar); 
  }

/* Atomic Data */
foo(1,2,3,4,5,6,7);
foo.bar // "{"0":1,"1":2,"2":3,"3":4,"4":5,"5":6,"6":7}"
foo.baz // [object Object]

/* Structured Data */
foo({1:2},[3,4],/5,6/,Date())
foo.bar //"{"0":{"1":2},"1":[3,4],"2":{},"3":"Tue Dec 17 2013 16:25:44 GMT-0800 (Pacific Standard Time)"}"
foo.baz // [object Object]

If preservation is needed instead of stringification, use the internal structured cloning algorithm.

If DOM nodes are passed, use XMLSerializer as in an unrelated question.

with (new XMLSerializer()) {serializeToString(document.documentElement) }

If running as a bookmarklet, you may need to wrap the each structured data argument in an Error constructor for JSON.stringify to work properly.

EDIT: This was written in 2014. You probably don't care about IE8 anymore and can forget about using innerText. Just use textContent and be done with it, hooray.

If you are the one supplying the text and no part of the text is supplied by the user (or some other source that you don't control), then setting innerHTML might be acceptable:

// * Fine for hardcoded text strings like this one or strings you otherwise 
//   control.
// * Not OK for user-supplied input or strings you don't control unless
//   you know what you are doing and have sanitized the string first.
document.getElementById('myspan').innerHTML = 'newtext';

However, as others note, if you are not the source for any part of the text string, using innerHTML can subject you to content injection attacks like XSS if you're not careful to properly sanitize the text first.

If you are using input from the user, here is one way to do it securely while also maintaining cross-browser compatibility:

var span = document.getElementById('myspan');
span.innerText = span.textContent = 'newtext';

Firefox doesn't support innerText and IE8 doesn't support textContent so you need to use both if you want to maintain cross-browser compatibility.

And if you want to avoid reflows (caused by innerText) where possible:

var span = document.getElementById('myspan');
if ('textContent' in span) {
    span.textContent = 'newtext';
} else {
    span.innerText = 'newtext';
}

If you would migrate your project to Spring Boot 1.4, you could use new annotation @MockBean for faking MyDependentObject. With that feature you could remove Mockito's @Mock and @InjectMocks annotations from your test.

I created this a few months ago for a project.

 ".+?"|[^"]+?(?=,)|(?<=,)[^"]+

It works in C# and the Debuggex was happy when I selected Python and PCRE. Javascript doesn't recognize this form of Proceeded By ?<=....

For your values, it will create matches on

123
,2.99
,AMO024
,Title
"Description, more info"
,
,123987564

Note that anything in quotes doesn't have a leading comma, but attempting to match with a leading comma was required for the empty value use case. Once done, trim values as necessary.

I use RegexHero.Net to test my Regex.

 var svg; // if you have variable declared and not assigned value.
 // then you make a mistake by appending elements to that before creating element    
 svg.appendChild(document.createElement("g"));
 // at some point you assign to svg
 svg = document.createElementNS('http://www.w3.org/2000/svg', "svg")
 // then you put it in DOM
 document.getElementById("myDiv").appendChild(svg)
 // it wont render unless you manually change myDiv DOM with DevTools

// to fix assign before you append
var svg = createElement("svg", [
    ["version", "1.2"],
    ["xmlns:xlink", "http://www.w3.org/1999/xlink"],
    ["aria-labelledby", "title"],
    ["role", "img"],
    ["class", "graph"]
]);
function createElement(tag, attributeArr) {
      // .createElementNS  NS is must! Does not draw without
      let elem = document.createElementNS('http://www.w3.org/2000/svg', tag);             
      attributeArr.forEach(element => elem.setAttribute(element[0], element[1]));
      return elem;
}
// extra: <circle> for example requires attributes to render. Check if missing.

Another way is to use FIXED function, you can specify the number of decimal places but it defaults to 2 if the places aren't specified, i.e.

=FIXED(E5,2)

or just

=FIXED(E5)

if the variable is a string

bool result = string.IsNullOrEmpty(variableToTest);

if you only have an object which may or may not contain a string then

bool result = string.IsNullOrEmpty(variableToTest as string);

You don't need to give local path. just give cdn link of bootstrap datetimepicker. and it works.

If you place your buttons inside a div with class "btn-group" the buttons inside will stretch to the same size as the largest button.

eg:

<div class="btn-group">
  <button type="button" class="btn btn-default">Left</button>
  <button type="button" class="btn btn-default">Middle</button>
  <button type="button" class="btn btn-default">Right</button>
</div> 

Bootstrap Button Groups

You can set display attribute as none to hide a label.

<label id="excel-data-div" style="display: none;"></label>

Recommended (reduce with default value)

Array.prototype.reduce can be used to iterate through the array, adding the current element value to the sum of the previous element values.

console.log(_x000D_
  [1, 2, 3, 4].reduce((a, b) => a + b, 0)_x000D_
)_x000D_
console.log(_x000D_
  [].reduce((a, b) => a + b, 0)_x000D_
)

Without default value

You get a TypeError

console.log(_x000D_
  [].reduce((a, b) => a + b)_x000D_
)

Prior to ES6's arrow functions

console.log(_x000D_
  [1,2,3].reduce(function(acc, val) { return acc + val; }, 0)_x000D_
)_x000D_
_x000D_
console.log(_x000D_
  [].reduce(function(acc, val) { return acc + val; }, 0)_x000D_
)

Non-number inputs

If non-numbers are possible inputs, you may want to handle that?

console.log(_x000D_
  ["hi", 1, 2, "frog"].reduce((a, b) => a + b)_x000D_
)_x000D_
_x000D_
let numOr0 = n => isNaN(n) ? 0 : n_x000D_
_x000D_
console.log(_x000D_
  ["hi", 1, 2, "frog"].reduce((a, b) => _x000D_
    numOr0(a) + numOr0(b))_x000D_
)

Non-recommended dangerous eval use

We can use eval to execute a string representation of JavaScript code. Using the Array.prototype.join function to convert the array to a string, we change [1,2,3] into "1+2+3", which evaluates to 6.

console.log(_x000D_
  eval([1,2,3].join('+'))_x000D_
)_x000D_
_x000D_
//This way is dangerous if the array is built_x000D_
// from user input as it may be exploited eg: _x000D_
_x000D_
eval([1,"2;alert('Malicious code!')"].join('+'))

Of course displaying an alert isn't the worst thing that could happen. The only reason I have included this is as an answer Ortund's question as I do not think it was clarified.

I prefer python -m json.tool which seems to be available per default on most *nix operating systems per default.

$ echo '{"foo":1, "bar":2}' | python -m json.tool
{
    "bar": 2, 
    "foo": 1
}

Note: Depending on your version of python, all keys might get sorted alphabetically, which can or can not be a good thing. With python 2 it was the default to sort the keys, while in python 3.5+ they are no longer sorted automatically, but you have the option to sort by key explicitly:

$ echo '{"foo":1, "bar":2}' | python3 -m json.tool --sort-keys
{
    "bar": 2, 
    "foo": 1
}

Keep your scripts right before </body>. Async can be used with scripts located there in a few circumstances (see discussion below). Defer won't make much of a difference for scripts located there because the DOM parsing work has pretty much already been done anyway.

Here's an article that explains the difference between async and defer: http://peter.sh/experiments/asynchronous-and-deferred-javascript-execution-explained/.

Your HTML will display quicker in older browsers if you keep the scripts at the end of the body right before </body>. So, to preserve the load speed in older browsers, you don't want to put them anywhere else.

If your second script depends upon the first script (e.g. your second script uses the jQuery loaded in the first script), then you can't make them async without additional code to control execution order, but you can make them defer because defer scripts will still be executed in order, just not until after the document has been parsed. If you have that code and you don't need the scripts to run right away, you can make them async or defer.

You could put the scripts in the <head> tag and set them to defer and the loading of the scripts will be deferred until the DOM has been parsed and that will get fast page display in new browsers that support defer, but it won't help you at all in older browsers and it isn't really any faster than just putting the scripts right before </body> which works in all browsers. So, you can see why it's just best to put them right before </body>.

Async is more useful when you really don't care when the script loads and nothing else that is user dependent depends upon that script loading. The most often cited example for using async is an analytics script like Google Analytics that you don't want anything to wait for and it's not urgent to run soon and it stands alone so nothing else depends upon it.

Usually the jQuery library is not a good candidate for async because other scripts depend upon it and you want to install event handlers so your page can start responding to user events and you may need to run some jQuery-based initialization code to establish the initial state of the page. It can be used async, but other scripts will have to be coded to not execute until jQuery is loaded.

This is what I did and it works so far in a MVC 5 application.

Controller's return type is ContentResult.

public ContentResult DoSomething()
{
    if(somethingIsTrue)
    {
        Response.StatusCode = 500 //Anything other than 2XX HTTP status codes should work
        Response.Write("My Message");
        return new ContentResult();
    }

    //Do something in here//
    string json = "whatever json goes here";

    return new ContentResult{Content = json, ContentType = "application/json"};
}

And on client side this is what ajax function looks like

$.ajax({
    type: "POST",
    url: URL,
    data: DATA,
    dataType: "json",
    success: function (json) {
        //Do something with the returned json object.
    },
    error: function (xhr, status, errorThrown) {
        //Here the status code can be retrieved like;
        xhr.status;

        //The message added to Response object in Controller can be retrieved as following.
        xhr.responseText;
    }
});

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

There are some problems implementing this which the original accepted answer does not answer:

1. The onscroll event of the window is firing very often. This implies that you either have to use a very performant listener, or you have to delay the listener somehow. jQuery Creator John Resig states here how a delayed mechanism can be implemented, and the reasons why you should do it. In my opinion, given todays browsers and environments, a performant listener will do as well. Here is an implementation of the pattern suggested by John Resig
2. The way position:fixed works in css, if you scroll down the page and move an element from position:static to position: fixed, the page will "jump" a little because the document "looses" the height of the element. You can get rid of that by adding the height to the scrollTop and replace the lost height in the document body with another object. You can also use that object to determine if the sticky item has already been moved to position: fixed and reduce the calls to the code reverting position: fixed to the original state: Look at the fiddle here
3. Now, the only expensive thing in terms of performance the handler is really doing is calling scrollTop on every call. Since the interval bound handler has also its drawbacks, I'll go as far as to argue here that you can reattach the event listener to the original scroll Event to make it feel snappier without many worries. You'll have to profile it though, on every browser you target / support. See it working here

Here's the code:

JS

/* Initialize sticky outside the event listener as a cached selector.
 * Also, initialize any needed variables outside the listener for 
 * performance reasons - no variable instantiation is happening inside the listener.
 */
var sticky = $('#sticky'),
    stickyClone,
    stickyTop = sticky.offset().top,
    scrollTop,
    scrolled = false,
    $window = $(window);

/* Bind the scroll Event */
$window.on('scroll', function (e) {
    scrollTop = $window.scrollTop();

    if (scrollTop >= stickyTop && !stickyClone) {
        /* Attach a clone to replace the "missing" body height */
        stickyClone = sticky.clone().prop('id', sticky.prop('id') + '-clone')
        stickyClone = stickyClone.insertBefore(sticky);
        sticky.addClass('fixed');
    } else if (scrollTop < stickyTop && stickyClone) {
        /* Since sticky is in the viewport again, we can remove the clone and the class */
        stickyClone.remove();
        stickyClone = null;
        sticky.removeClass('fixed');
    }
});

CSS

body {
    margin: 0
}
.sticky {
    padding: 1em;
    background: black;
    color: white;
    width: 100%
}
.sticky.fixed {
    position: fixed;
    top: 0;
    left: 0;
}
.content {
    padding: 1em
}

HTML

<div class="container">
  <div id="page-above" class="content">
    <h2>Some Content above sticky</h2>
    ...some long text...
  </div>
  <div id="sticky" class="sticky">This is sticky</div>
  <div id="page-content" class="content">
    <h2>Some Random Page Content</h2>...some really long text...
  </div>
</div>

There are lots of way we can do that and simply you can try following.

ls /home/user/new | tr '\n' '\n' | grep .txt

Another method:

cd /home/user/new && ls *.txt

use binary search

public class FindSqrt {

    public static void main(String[] strings) {

        int num = 10000;
        System.out.println(sqrt(num, 0, num));
    }

    private static int sqrt(int num, int min, int max) {
        int middle = (min + max) / 2;
        int x = middle * middle;
        if (x == num) {
            return middle;
        } else if (x < num) {
            return sqrt(num, middle, max);
        } else {
            return sqrt(num, min, middle);
        }
    }
}

If you want to be sure to not have to deal with quotes for the syntax stash@{x}, use Git 2.11 (Q4 2016)

See commit a56c8f5 (24 Oct 2016) by Aaron M Watson (watsona4).
^{(Merged by Junio C Hamano -- gitster -- in commit 9fa1f90, 31 Oct 2016)}

stash: allow stashes to be referenced by index only

Instead of referencing "stash@{n}" explicitly, make it possible to simply reference as "n".
Most users only reference stashes by their position in the stash stack (what I refer to as the "index" here).

The syntax for the typical stash (stash@{n}) is slightly annoying and easy to forget, and sometimes difficult to escape properly in a script.

Because of this the capability to do things with the stash by simply referencing the index is desirable.

So:

git stash drop 1
git stash pop 1
git stash apply 1
git stash show 1

Something that I saw people using is stringexpression > ''. This may be not the fastest one, but happens to be one of the shortest.

Tried it on MS SQL as well as on PostgreSQL.

I've faced with the same problem, have struggled a couple of day with it and should say that the most easiest way to overcome I found this is to use fragment.hide() / fragment.show() when tab is selected/unselected().

public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft)
{
    if (mFragment != null)
        ft.hide(mFragment);
}

When screen rotation occurs all parent and child fragments get correctly destroyed.

This approach has also one additional advantage - using hide()/show() does not cause fragment views to loose their state, so there is no need to restore the previous scroll position for ScrollViews for example.

The problem is that I don't know whether it is correct to not detach fragments when they are not visible. I think the official example of TabListener is designed with a thought in mind that fragments are reusable and you should not pollute with them memory, however, I think if you have just a few tabs and you know that users will be switching between them frequently it will be appropriate to keep them attached to the current activity.

I would like to hear comments from more experienced developers.

As of release 1.7 Dashboard supports user authentication based on:

• Authorization: Bearer <token> header passed in every request to Dashboard. Supported from release 1.6. Has the highest priority. If present, login view will not be shown.
• Bearer Token that can be used on Dashboard login view.
• Username/password that can be used on Dashboard login view.
• Kubeconfig file that can be used on Dashboard login view.

— Dashboard on Github

Token

Here Token can be Static Token, Service Account Token, OpenID Connect Token from Kubernetes Authenticating, but not the kubeadm Bootstrap Token.

With kubectl, we can get an service account (eg. deployment controller) created in kubernetes by default.

$ kubectl -n kube-system get secret
# All secrets with type 'kubernetes.io/service-account-token' will allow to log in.
# Note that they have different privileges.
NAME                                     TYPE                                  DATA      AGE

Kubeconfig

The dashboard needs the user in the kubeconfig file to have either username & password or token, but admin.conf only has client-certificate. You can edit the config file to add the token that was extracted using the method above.

$ kubectl config set-credentials cluster-admin --token=bearer_token

Alternative (Not recommended for Production)

Here are two ways to bypass the authentication, but use for caution.

Deploy dashboard with HTTP

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/alternative/kubernetes-dashboard.yaml

Dashboard can be loaded at http://localhost:8001/ui with kubectl proxy.

Granting admin privileges to Dashboard's Service Account

$ cat <<EOF | kubectl create -f -
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: kubernetes-dashboard
  labels:
    k8s-app: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard
  namespace: kube-system
EOF

Afterwards you can use Skip option on login page to access Dashboard.

If you are using dashboard version v1.10.1 or later, you must also add --enable-skip-login to the deployment's command line arguments. You can do so by adding it to the args in kubectl edit deployment/kubernetes-dashboard --namespace=kube-system.

Example:

      containers:
      - args:
        - --auto-generate-certificates
        - --enable-skip-login            # <-- add this line
        image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1

From Windows 10 version 1607, the limitation has been removed by setting a registry key

Roughly, partial does something like this (apart from keyword args support etc):

def partial(func, *part_args):
    def wrapper(*extra_args):
        args = list(part_args)
        args.extend(extra_args)
        return func(*args)

    return wrapper

So, by calling partial(sum2, 4) you create a new function (a callable, to be precise) that behaves like sum2, but has one positional argument less. That missing argument is always substituted by 4, so that partial(sum2, 4)(2) == sum2(4, 2)

As for why it's needed, there's a variety of cases. Just for one, suppose you have to pass a function somewhere where it's expected to have 2 arguments:

class EventNotifier(object):
    def __init__(self):
        self._listeners = []

    def add_listener(self, callback):
        ''' callback should accept two positional arguments, event and params '''
        self._listeners.append(callback)
        # ...

    def notify(self, event, *params):
        for f in self._listeners:
            f(event, params)

But a function you already have needs access to some third context object to do its job:

def log_event(context, event, params):
    context.log_event("Something happened %s, %s", event, params)

So, there are several solutions:

A custom object:

class Listener(object):
   def __init__(self, context):
       self._context = context

   def __call__(self, event, params):
       self._context.log_event("Something happened %s, %s", event, params)


 notifier.add_listener(Listener(context))

Lambda:

log_listener = lambda event, params: log_event(context, event, params)
notifier.add_listener(log_listener)

With partials:

context = get_context()  # whatever
notifier.add_listener(partial(log_event, context))

Of those three, partial is the shortest and the fastest. (For a more complex case you might want a custom object though).

Say:

sed "s|\$ROOT|${HOME}|" abc.sh

Note:

• Use double quotes so that the shell would expand variables.
• Use a separator different than / since the replacement contains /
• Escape the $ in the pattern since you don't want to expand it.

EDIT: In order to replace all occurrences of $ROOT, say

sed "s|\$ROOT|${HOME}|g" abc.sh

Per Byron's answer, you can't set networkaddress.cache.ttl or networkaddress.cache.negative.ttl as System Properties by using the -D flag or calling System.setProperty because these are not System properties - they are Security properties.

If you want to use a System property to trigger this behavior (so you can use the -D flag or call System.setProperty), you will want to set the following System property:

-Dsun.net.inetaddr.ttl=0

This system property will enable the desired effect.

But be aware: if you don't use the -D flag when starting the JVM process and elect to call this from code instead:

java.security.Security.setProperty("networkaddress.cache.ttl" , "0")

This code must execute before any other code in the JVM attempts to perform networking operations.

This is important because, for example, if you called Security.setProperty in a .war file and deployed that .war to Tomcat, this wouldn't work: Tomcat uses the Java networking stack to initialize itself much earlier than your .war's code is executed. Because of this 'race condition', it is usually more convenient to use the -D flag when starting the JVM process.

If you don't use -Dsun.net.inetaddr.ttl=0 or call Security.setProperty, you will need to edit $JRE_HOME/lib/security/java.security and set those security properties in that file, e.g.

networkaddress.cache.ttl = 0
networkaddress.cache.negative.ttl = 0

But pay attention to the security warnings in the comments surrounding those properties. Only do this if you are reasonably confident that you are not susceptible to DNS spoofing attacks.

In C++11, you can use std::any_of instead.

An example to find if there is any zero in the array:

std::array<int,3> foo = {0,1,-1};
if ( std::any_of(foo.begin(), foo.end(), [](int i){return i==0;}) )
std::cout << "zero found...";

Try this :

import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;


public class Test {

    public static void main(String[] args) {
        JFrame f = new JFrame();
        try {
            f.setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("test.jpg")))));
        } catch (IOException e) {
            e.printStackTrace();
        }
        f.pack();
        f.setVisible(true);
    }

}

By the way, this will result in the content pane not being a container. If you want to add things to it you have to subclass a JPanel and override the paintComponent method.

Try giving your Button in your main.xml a more descriptive name such as:

<Button
                android:id="@+id/buttonXYZ"

(use lowercase in your xml files, at least, the first letter)

And then in your MainActivity class, declare it as:

Button buttonXYZ;

In your onCreate(Bundle savedInstanceState) method, define it as:

buttonXYZ = (Button) findViewById(R.id.buttonXYZ);

Also, move the Buttons/TextViews outside and place them before the .setOnClickListener - it makes the code cleaner.

Username = (EditText)findViewById(R.id.Username);
CompanyID = (EditText)findViewById(R.id.CompanyID);

Use the <text> pseudo-element, as described here, to force the Razor compiler back into content mode:

<script type="text/javascript">

    // Some JavaScript code here to display map, etc.


    // Now add markers
    @foreach (var item in Model) {
        <text>
            var markerlatLng = new google.maps.LatLng(@(Model.Latitude), @(Model.Longitude));
            var title = '@(Model.Title)';
            var description = '@(Model.Description)';
            var contentString = '<h3>' + title + '</h3>' + '<p>' + description + '</p>'

            var infowindow = new google.maps.InfoWindow({
                content: contentString
            });

            var marker = new google.maps.Marker({
                position: latLng,
                title: title,
                map: map,
                draggable: false
            });

            google.maps.event.addListener(marker, 'click', function () {
                infowindow.open(map, marker);
            });
        </text>
    }
</script>

Update:

Scott Guthrie recently posted about @: syntax in Razor, which is slightly less clunky than the <text> tag if you just have one or two lines of JavaScript code to add. The following approach would probably be preferable, because it reduces the size of the generated HTML. (You could even move the addMarker function to a static, cached JavaScript file to further reduce the size):

<script type="text/javascript">

    // Some JavaScript code here to display map, etc.
    ...
    // Declare addMarker function
    function addMarker(latitude, longitude, title, description, map)
    {
        var latLng = new google.maps.LatLng(latitude, longitude);
        var contentString = '<h3>' + title + '</h3>' + '<p>' + description + '</p>';

        var infowindow = new google.maps.InfoWindow({
            content: contentString
        });

        var marker = new google.maps.Marker({
            position: latLng,
            title: title,
            map: map,
            draggable: false
        });

        google.maps.event.addListener(marker, 'click', function () {
            infowindow.open(map, marker);
        });
    }

    // Now add markers
    @foreach (var item in Model) {
        @:addMarker(@item.Latitude, @item.Longitude, '@item.Title', '@item.Description', map);
    }
</script>

Updated the above code to make the call to addMarker more correct.

To clarify, the @: forces Razor back into text mode, even though addMarker call looks a lot like C# code. Razor then picks up the @item.Property syntax to say that it should directly output the contents of those properties.

Update 2

It's worth noting that View code really isn't a good place to put JavaScript code. JavaScript code should be placed in a static .js file, and then it should get the data that it needs either from an Ajax call or by scanning data- attributes from the HTML. Besides making it possible to cache your JavaScript code, this also avoids issues with encoding, since Razor is designed to encode for HTML, but not JavaScript.

View Code

@foreach(var item in Model)
{
    <div data-marker="@Json.Encode(item)"></div>
}

JavaScript code

$('[data-marker]').each(function() {
    var markerData = $(this).data('marker');
    addMarker(markerData.Latitude, markerData.Longitude,
              markerData.Description, markerData.Title);
});

I would do it this way

 $("#idElement").val('optionValue').trigger('change');

A rather nice addition to @MartijnPieters answer is to get back a dictionary sorted by occurrence since Collections.most_common only returns a tuple. I often couple this with a json output for handy log files:

from collections import Counter, OrderedDict

x = Counter({'a':5, 'b':3, 'c':7})
y = OrderedDict(x.most_common())

With the output:

OrderedDict([('c', 7), ('a', 5), ('b', 3)])
{
  "c": 7, 
  "a": 5, 
  "b": 3
}

I think Amarghosh answered correctly. If you want to Initialize an empty string(without knowing the size) the best way is:

//this will create an empty string without no memory allocation. 
char str[]="";// it is look like {0}

But if you want initialize a string with a fixed memory allocation you can do:

// this is better if you know your string size.    
char str[5]=""; // it is look like {0, 0, 0, 0, 0} 

The -HideTableHeaders parameter unfortunately still causes the empty lines to be printed (and table headers appearently are still considered for column width). The only way I know that could reliably work here would be to format the output yourself:

| % { '{0,10} {1,20} {2,20}' -f $_.Operation,$_.AttributeName,$_.AttributeValue }

If you are using a set Animation like me you should add the interpolation inside the set tag:

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator">

 <rotate
    android:duration="5000"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:startOffset="0"
    android:toDegrees="360" />

 <alpha
    android:duration="200"
    android:fromAlpha="0.7"
    android:repeatCount="infinite"
    android:repeatMode="reverse"
    android:toAlpha="1.0" />

</set>

That Worked for me.

The DATE_ADD() function will do the trick. (You can also use the ADDTIME() function if you're running at least v4.1.1.)

For your query, this would be:

SELECT * 
FROM courses 
WHERE DATE_ADD(now(), INTERVAL 2 HOUR) > start_time

Or,

SELECT * 
FROM courses 
WHERE ADDTIME(now(), '02:00:00') > start_time

Something like this:

 DataTable dt = new DataTable();

 // For each row, print the values of each column.
    foreach(DataRow row in dt .Rows)
    {
        foreach(DataColumn column in dt .Columns)

You may have this issue as well if you have environment variable GCC_ROOT pointing to a wrong location. Probably simplest fix could be (on *nix like system):

unset GCC_ROOT

in more complicated cases you may need to repoint it to proper location

First of all, Thank you DTing for awesome answer. It's pretty much perfect.

For those who are suffering from not having GCC access in shared hosting, Go for ActivePython instead of normal python like Scott Stafford mentioned. Here are the commands for that.

wget http://downloads.activestate.com/ActivePython/releases/2.7.13.2713/ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785.tar.gz

tar -zxvf ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785.tar.gz

cd ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785

./install.sh

It will ask you path to python directory. Enter

../../.localpython

Just replace above as Step 1 in DTing's answer and go ahead with Step 2 after that. Please note that ActivePython package URL may change with new release. You can always get new URL from here : http://www.activestate.com/activepython/downloads

Based on URL you need to change the name of tar and cd command based on file received.

1. Ctrl + 5

2. Delete the relevant workspace

closest() selects the first element that matches the selector, up from the DOM tree. Begins from the current element and travels up.

parent() selects one element up (single level up) the DOM tree.

parents() method is similar to parent() but selects all the matching elements up the DOM tree. Begins from the parent element and travels up.

You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.

When using storageClass Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.

To solve your issue:

• Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi)
• Remove the storageClass-line from the PersistentVolumeClaim
• Remove the StorageClass from your cluster

How do these pieces play together?

At creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.

The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.

The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.

A PersistentVolume without StorageClass is considered to be static.

"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.

Example PersistentVolume

In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ckan-pv-home
  labels:
    type: local
spec:
  capacity:
    storage: 100Mi
  hostPath:
    path: "/mnt/data/ckan"

The PersistentVolumeSpec allows us to define multiple attributes. I chose a hostPath volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.

Additional Resources:

• Configure PersistentVolume Guide

There is an function, but it's extra: http://docs.jquery.com/Cookbook/wait

This little snippet allows you to wait:

$.fn.wait = function(time, type) {
    time = time || 1000;
    type = type || "fx";
    return this.queue(type, function() {
        var self = this;
        setTimeout(function() {
            $(self).dequeue();
        }, time);
    });
};

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

You can accomplish this (if I understand what you are trying to do) using dynamic SQL.

The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.

So you can use something like this approach:

SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue 
    + ' AS fld1 FROM tbl' + @KeyValue

EXEC (@stmt)

First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:

'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'

At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE (or EXEC for short).

The old-school sp_executesql procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.

FOLLOWUP

EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.

Consider what would happen if @KeyValue contained the string:

'1 AS foo; DROP TABLE students; -- '

The string we would produce as a SQL statement would be:

'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'

When we EXECUTE that string as a SQL statement:

INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...

And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)

One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'. If an illegal character is found, then reject the value, and exit without executing any SQL.

In Bash, you can use pseudo-device files which can open a TCP connection to the associated socket. The syntax is /dev/$tcp_udp/$host_ip/$port.

Here is simple example to test whether Memcached is running:

</dev/tcp/localhost/11211 && echo Port open || echo Port closed

Here is another test to see if specific website is accessible:

$ echo "HEAD / HTTP/1.0" > /dev/tcp/example.com/80 && echo Connection successful.
Connection successful.

For more info, check: Advanced Bash-Scripting Guide: Chapter 29. /dev and /proc.

Related: Test if a port on a remote system is reachable (without telnet) at SuperUser.

For more examples, see: How to open a TCP/UDP socket in a bash shell (article).

 a=input()
 print(a[::-1])

The above code recieves the input from the user and prints an output that is equal to the reverse of the input by adding [::-1].

OUTPUT:

>>> Happy 
>>> yppaH

But when it comes to the case of sentences, view the code output below:

>>> Have a happy day
>>> yad yppah a evaH

But if you want only the characters of the string to be reversed and not the sequence of string, try this:

a=input().split() #Splits the input on the basis of space (" ")
for b in a: #declares that var (b) is any value in the list (a)
    print(b[::-1], end=" ") #End declares to print the character in its quotes (" ") without a new line.

In the above code in line 2 in I said that ** variable b is any value in the list (a)** I said var a to be a list because when you use split in an input the variable of the input becomes a list. Also remember that split can't be used in the case of int(input())

OUTPUT:

>>> Have a happy day
>>> evaH a yppah yad

If we don't add end(" ") in the above code then it will print like the following:

>>> Have a happy day
>>> evaH
>>> a
>>> yppah
>>> yad

Below is an example to understand end():

CODE:

for i in range(1,6):
     print(i) #Without end()

OUTPUT:

>>> 1
>>> 2
>>> 3
>>> 4
>>> 5

Now code with end():

for i in range(1,6):
    print(i, end=" || ")

OUTPUT:

>>> 1 || 2 || 3 || 4 || 5 ||

XMLStarlet or another XPath engine is the correct tool for this job.

For instance, with data.xml containing the following:

<root>
  <item> 
    <title>15:54:57 - George:</title>
    <description>Diane DeConn? You saw Diane DeConn!</description> 
  </item> 
  <item> 
    <title>15:55:17 - Jerry:</title> 
    <description>Something huh?</description>
  </item>
</root>

...you can extract only the first title with the following:

xmlstarlet sel -t -m '//title[1]' -v . -n <data.xml

Trying to use sed for this job is troublesome. For instance, the regex-based approaches won't work if the title has attributes; won't handle CDATA sections; won't correctly recognize namespace mappings; can't determine whether a portion of the XML documented is commented out; won't unescape attribute references (such as changing Brewster & Jobs to Brewster & Jobs), and so forth.

echo "echo "we are now going to work with ${ser}" " >> $servfile

Escape all " within quotes with \. Do this with variables like \$servicetest too:

echo "echo \"we are now going to work with \${ser}\" " >> $servfile    
echo "read -p \"Please enter a service: \" ser " >> $servfile
echo "if [ \$servicetest > /dev/null ];then " >> $servfile

Moreover, Swift 2 has debugPrint() (and CustomDebugStringConvertible protocol)!

Don't forget about debugPrint() which works like print() but most suitable for debugging.

Examples:

• Strings
  • print("Hello World!") becomes Hello World
  • debugPrint("Hello World!") becomes "Hello World" (Quotes!)
• Ranges
  • print(1..<6) becomes 1..<6
  • debugPrint(1..<6) becomes Range(1..<6)

Any class can customize their debug string representation via CustomDebugStringConvertible protocol.

For Ionic (Typescript) you have to double slash in order to scape the characters. For example (this is to match some special characters):

"^(?=.*[\\]\\[!¡\'=ªº\\-\\_ç@#$%^&*(),;\\.?\":{}|<>\+\\/])"

Pay attention to this ] [ - _ . / characters. They have to be double slashed. If you don't do that, you are going to have a type error in your code.

You could also supply variables on the command line with -PmavenUser=user -PmavenPassword=password.

This might be useful you can't use a gradle.properties file for some reason. E.g. on a build server we're using Gradle with the -g option so that each build plan has it's own GRADLE_HOME.

This issue for me was caused by having apowermirror running at the same time, from what I can tell any software that could use a different version of adb could cause these issues as others mention in this thread this can include Genymotion or from other threads unreal studio was the problem.

A race condition is an undesirable situation that occurs when a device or system attempts to perform two or more operations at the same time, but because of the nature of the device or system, the operations must be done in the proper sequence in order to be done correctly.

In computer memory or storage, a race condition may occur if commands to read and write a large amount of data are received at almost the same instant, and the machine attempts to overwrite some or all of the old data while that old data is still being read. The result may be one or more of the following: a computer crash, an "illegal operation," notification and shutdown of the program, errors reading the old data, or errors writing the new data.

On centOS7 I changed the file /etc/httpd/conf/httpd.conf

from AllowOverride None to AllowOverride All

A jQuery solution would be something like:

$(function () {
    $('input').blur();
});

Another way to get the EF version you are using is to open the Package Manager Console (PMC) in Visual Studio and type Get-Package at the prompt. The first line with be for EntityFramework and list the version the project has installed.

PM> Get-Package

It displays much more and you may have to scroll back up to find the EF line, but this is the easiest way I know of to find out.

While editing the code (because mild OCD), I noticed that weather is also a list. You should probably consider something like

echo $data[0]->weather[0]->weatherIconUrl[0]->value;

to make sure you are using the weatherIconUrl for the correct date instance.

This is an old question but still answering it in present-day context as many of the above answers may not work now.

The problem is that the Path is still pointing to the old version. Two solutions can be provided for resolution :

1. Uninstall old version of openssl package brew uninstall openssl and then reinstall the new version : brew install openssl
2. point the PATH to the new version of openssl.First install the new version and now(or if) you have installed the latest version, point the path to it: echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

I fixed this (for development) with a simple nginx proxy...

# /etc/nginx/sites-enabled/default
server {
  listen 80;
  root /path/to/Development/dir;
  index index.html;

  # from your example
  location /search {
    proxy_pass http://api.master18.tiket.com;
  }
}

Lets take an example where you want to print numbers from 0 to n in the same line. You can do this with the help of following code.

n=int(raw_input())
i=0
while(i<n):
    print i,
    i = i+1

At input, n = 5

Output : 0 1 2 3 4 

Actually you can fix it with following steps -

1. Do cls.__dict__
2. This will give you dictionary format output which will contain {'isFilled':True} or {'isFilled':False} depending upon what you have set.
3. Delete this entry - del cls.__dict__['isFilled']
4. You will be able to call the method now.

In this case, we delete the entry which overrides the method as mentioned by BrenBarn.

I have built an module for this if you want to add styles based on a condition like this:

maybe whole database + tables + fields should have the same charset??!

i.e.

  `ID` int(11) NOT NULL AUTO_INCREMENT,
  `Nombre` varchar(250) CHARACTER SET utf8 NOT NULL,
  -------------------------------------^here!!!!!!!!!!!
  PRIMARY KEY (`ID`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
  -------------------------------------------------^here!!!!!!!!!

have you tried doing it without the JSON object and just passed two basicnamevaluepairs? also, it might have something to do with your serversettings

Update: this is a piece of code I use:

InputStream is = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate)); 

try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(connection);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        Log.d("HTTP", "HTTP: OK");
    } catch (Exception e) {
        Log.e("HTTP", "Error in http connection " + e.toString());
    }

I think there's proper solution. Configure the yii\data\Sort object:

 $dataProvider = new ActiveDataProvider([
     'query' => $query,
     'sort'=> ['defaultOrder' => ['topic_order' => SORT_ASC]],
 ]);

I had a similar issue and i solved it by just rebuilding the virtual environment with virtualenv .

For me building a MacOS command line Swift app that depended on 3rd party Swift libs (e.g. SQLite) none of the above solutions seemed to work. What did work was directly adding the following path to my Runpath Search Paths in the Build Settings:

/Applications/Xcode.app/Contents//Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/

Doing that did give a warning at runtime saying that Xcode had found 2 versions of libswiftCore - which makes sense. Except that not including that line resulted in Xcode not finding any versions of libswiftCore.

Anyway, that'll do for me even if it doesn't seem right - my app is just a utility that I'm not intending to distribute and at least it runs now!

This may help

If there is not substantial history on one end (aka if it is just a single readme commit on the github end), I often find it easier to manually copy the readme to my local repo and do a git push -f to make my version the new root commit.

I find it is slightly less complicated, doesn't require remembering an obscure flag, and keeps the history a bit cleaner.

Read SVNBook | Client Credentials.

With modern SVN you can just run svn auth to display the list of cached credentials. Don't forget to make sure that you run up-to-date SVN client version because svn auth was introduced in version 1.9. The last line will specify the path to credential store which by default is %APPDATA%\Subversion\auth on Windows and ~/.subversion/auth/ on Unix-like systems.

PS C:\Users\MyUser> svn auth
------------------------------------------------------------------------
Credential kind: svn.simple

Credentials cache in 'C:\Users\MyUser\AppData\Roaming\Subversion' contains 5 credentials

No need for pipes, xargs, exec, or anything:

find . -name .svn -delete

Edit: Just kidding, evidently -delete calls unlinkat() under the hood, so it behaves like unlink or rmdir and will refuse to operate on directories containing files.

Actually, above codes can be:

>>> sorted(['Some','words','sort','differently'],key=str.lower)

According to https://docs.python.org/2/library/functions.html?highlight=sorted#sorted, key specifies a function of one argument that is used to extract a comparison key from each list element: key=str.lower. The default value is None (compare the elements directly).

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

I had a similar problem, but in my case there were no files missing, there was an error in how the pdb output file was defined: I forgot the suffix .pdb (I found out with the debug logging trick).

strToLower should return a char * instead of a char. Something like this would do.

char *strToLower(char *cString)

for /l %%a in (254, -1, 1) do ( 
    for /l %%b in (1, 1, 254) do (
        for %%c in (20, 168) do (
            for %%e in (172, 192) do (
                ping /n 1 %%e.%%c.%%b.%%a>>ping.txt
            )
        )
    )
)

Some googling led me to the following post:

http://www.developerweb.net/forum/showthread.php?t=3434

The code provided in the post is in C, but it shouldn't be too hard to rewrite it to Java.

Insert the following into decompile.jar.sh

# Usage: decompile.jar.sh some.jar [-d]

# clean target folders
function clean_target {
  rm -rf $unjar $src $jad_log
}

# clean all debug stuff
function clean_stuff {
  rm -rf $unjar $jad_log
}

# the main function
function work {
  jar=$1
  unjar=`basename $jar.unjar`
  src=`basename $jar.src`
  jad_log=jad.log

  clean_target

  unzip -q $jar -d $unjar
  jad -d $src -ff -r -lnc -o -s java $unjar/**/*.class > $jad_log 2>&1

  if [ ! $debug ]; then
    clean_stuff
  fi

  if [ -d $src ] 
    then
      echo "$jar has been decompiled to $src"
    else
      echo "Got some problems check output or run in debug mode"
  fi
}

function usage {
  echo "This script extract and decompile JAR file"
  echo "Usage: $0 some.jar [-d]"
  echo "    where: some.jar is the target to decompile"
  echo "    use -d for debug mode"
}

# check params
if [ -n "$1" ]
  then
    if [ "$2" == "-d" ]; then
      debug=true
      set -x
    fi
    work $1
  else
    usage
fi

• chmod +x decomplie.jar.sh //executable
• ln -s ./decomplie.jar.s /usr/bin/dj

Ready to use, just type dj your.jar and you will get your.jar.src folder with sources. Use -d option for debug mode.

In our case (next to trying Dependency Walker) it was a faulty manifest file, mixing 64 bits and 32 bits. We use two extra files while running in Debug mode: dbghelp.dll and Microsoft.DTfW.DHL.manifest. The manifest file looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- $Id -->
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
    <noInheritable />
    <assemblyIdentity type="win32" name="Microsoft.DTfW.DHL" version="6.11.1.404" processorArchitecture="x86" />
    <file name="dbghelp.dll" />
</assembly>

Notice the 'processorArchitecture' field. It was set to "amd64" instead of "x86". It's probably not always the cause, but in our case it was the root cause, so it may be helpful to some. For 64-bit runs, you'll want "amd64" in there.

Solved.

I was running into the exact same error message when trying to execute the following script (partial) against a remote VM that was configured to be in the WORKGROUP.

Restart-Computer -ComputerName MyComputer -Authentication Default -Credential $cred -force

I noticed I could run the script from another VM in the same WORKGROUP when I disabled the firewall but still couldn't do it from a machine on the domain. Those two things along with Stackflow suggestions is what brought me to the following solution:

Note: Change these settings at your own risk. You should understand the security implications of these changes before applying them.

On the remote machine:

• Make sure you re-enable your Firewall if you've disabled it during testing.
• Run Enable-PSRemoting from PowerShell with success
• Go into wf.msc (Windows Firewall with Advanced Security)
• Confirm the Private/Public inbound 'Windows Management Instrumentation (DCOM-In)' rule is enabled AND make sure the 'Remote Address' property is 'Any' or something more secure.
• Confirm the Private/Public inbound 'Windows Management Instrumentation (WMI-In)' rule is enabled AND make sure the 'Remote Address' property is 'Any' or something more secure.

Optional: You may also need to perform the following if you want to run commands like 'Enter-PSSession'.

• Confirm the Private/Public inbound 'Windows Management Instrumentation (ASync-In)' rule is enabled AND make sure the 'Remote Address' property is 'Any' or something more secure.
• Open up an Inbound TCP port to 5985

IMPORTANT! - It's taking my remote VM about 2 minutes or so after it reboots to respond to the 'Enter-PSSession' command even though other networking services are starting up without problems. Give it a couple minutes and then try.

Side Note: Before I changed the 'Remote Address' property to 'Any', both of the rules were set to 'Local subnet'.

When you have 'NA' values in the column, then

sum(as.numeric(JuneData1$Account.Balance), na.rm = TRUE)

Use css:

<style>
input[name=btnsubmit]:active {
color: green;
}
</style>

#header.overlay {
    background-color: SlateGray;
    position:relative;
    width: 100%;
    height: 100%;
    opacity: 0.20;
    -moz-opacity: 20%;
    -webkit-opacity: 20%;
    z-index: 2;
}

Something like this. Just add the overlay class to the header, obviously.

git reset --hard 1258f0d0aae

But be careful, if the descendant commits between 1258f0d0aae and HEAD are not referenced in other branches it'll be tedious (but not impossible) to recover them, so you'd better to create a "backup" branch at current HEAD, checkout master, and reset to the commit you want.

Also, be sure that you don't have uncommitted changes before a reset --hard, they will be truly lost (no way to recover).

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

You can use the IPython.display.clear_output to clear the output as mentioned in cel's answer. I would add that for me the best solution was to use this combination of parameters to print without any "shakiness" of the notebook:

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print(i, flush=True)

Django 2.0 removes the django.core.urlresolvers module, which was moved to django.urls in version 1.10. You should change any import to use django.urls instead, like this:

from django.urls import reverse

Note that Django 2.0 removes some features that previously were in django.core.urlresolvers, so you might have to make some more changes before your code works. See the features deprecated in 1.9 for details on those additional changes.

Use the rawurlencode function instead.

To me, this is the biggest mistake in Sublime. Alt+F3 is hard to reach/remember, and Ctrl+Shift+G makes no sense considering Ctrl+D is "add next instance to selection".

Add this to your User Key Bindings (Preferences > Key Bindings):

{ "keys": ["ctrl+shift+d"], "command": "find_all_under" },

Now you can highlight something, press Ctrl+Shift+D, and it will add every other instance in the file to the selection.

Unfortunately there is no such a thing as Lock/Unlock. What you have to do is:

1. Click on "Filter Current Log..."
2. Select the XML tab and click on "Edit query manually"

3. Enter the below query:

   <QueryList>
     <Query Id="0" Path="Security">
       <Select Path="Security">
       *[EventData[Data[@Name='LogonType']='7']
        and
        (System[(EventID='4634')] or System[(EventID='4624')])
        ]</Select>
     </Query>
   </QueryList>
   

That's it

As I just figured, in case you have a model fitted on multiple linear regression, the above mentioned solution won't work.

You have to create your line manually as a dataframe that contains predicted values for your original dataframe (in your case data).

It would look like this:

# read dataset
df = mtcars

# create multiple linear model
lm_fit <- lm(mpg ~ cyl + hp, data=df)
summary(lm_fit)

# save predictions of the model in the new data frame 
# together with variable you want to plot against
predicted_df <- data.frame(mpg_pred = predict(lm_fit, df), hp=df$hp)

# this is the predicted line of multiple linear regression
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_line(color='red',data = predicted_df, aes(x=mpg_pred, y=hp))

# this is predicted line comparing only chosen variables
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_smooth(method = "lm", se = FALSE)

Management studio creates scripts like:

insert table1 (foodate) values(CAST(N'2012-06-18 10:34:09.000' AS DateTime))

On Windows and Linux, press Ctrl+K, then release the keys and press O (the letter O, not Zero).

On macOS, press command+K, then O (without holding command).

This will open the active file tab in a new window/instance.
