You can also simply set your pandas column as list of id values with length same as of dataframe.

df['New_ID'] = range(880, 880+len(df))

I arrived at this question due to a problem with command line build for simulator in Xcode 7.2. In case anyone else gets here with the same issue, I will share the solution I found:

Apparently there is a bug in Xcode 7.2 that causes xcodebuild to fail when trying to build for simulator. The solution is to specify the option "-destination", e.g:

xcodebuild -project TestBuildCmd.xcodeproj -scheme TestBuildCmd -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6' build

Update

The above example command will build a binary including the graphics for iPhone 6 only. If the binary is run on other simulators, the iPhone 6 graphics is scaled to the platform. A better workaround which contains all graphics for all platforms is to specify the parameter PLATFORM_NAME=iphonesimulator, for example:

xcodebuild -project TestBuildCmd.xcodeproj -scheme TestBuildCmd -sdk iphonesimulator -arch i386 PLATFORM_NAME=iphonesimulator build

I have a similar situation, but I use the key and the certificate in different files.

in my case you can check the matching of the key and the lock by comparing the hashes (see https://michaelheap.com/curl-58-unable-to-set-private-key-file-server-key-type-pem/). This helped me to identify inconsistencies.

For Devs getting this error in Web API Project -

The GetOwinContext extension method is defined in System.Web.Http.Owin dll and one more package will be needed i.e. Microsoft.Owin.Host.SystemWeb. This package needs to be installed in your project from nuget.

I got this error while moving my code from my one project to another.

There are many ways of doing it, I'm listing a few here:

1. Use SizedBox if you want to set some specific space

   Row(
     children: <Widget>[
       Text("1"),
       SizedBox(width: 50), // give it width
       Text("2"),
     ],
   )
   

   

2. Use Spacer if you want both to be as far apart as possible.

   Row(
     children: <Widget>[
       Text("1"),
       Spacer(), // use Spacer
       Text("2"),
     ],
   )
   

   

3. Use mainAxisAlignment according to your needs:

   Row(
     mainAxisAlignment: MainAxisAlignment.spaceEvenly, // use whichever suits your need
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

4. Use Wrap instead of Row and give some spacing

   Wrap(
     spacing: 100, // set spacing here
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

5. Use Wrap instead of Row and give it alignment

   Wrap(
     alignment: WrapAlignment.spaceAround, // set your alignment
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

Run the following command on the terminal:

sudo apt-get autoremove ruby

You can simply use datetime diff and format for calculating difference.

<?php
$datetime1 = new DateTime('2009-10-11 12:12:00');
$datetime2 = new DateTime('2009-10-13 10:12:00');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%Y-%m-%d %H:%i:%s');
?>

For more information OF DATETIME format, refer: here
You can change the interval format in the way,you want.

Here is the working example

P.S. These features( diff() and format()) work with >=PHP 5.3.0 only

Addition to BeNdErR's answer:
The "other TEXT" element should have float:none, like:

    <div style="width:100%;">_x000D_
        <div style="float:left;width:30%; background:red;">...something something something  random text</div>_x000D_
        <div style="float:none; background:yellow;"> text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text  </div>_x000D_
    </div>

If you're having an issue where the Resources added are images and are not getting copied to your build folder on compiling. You need to change the "Build Action" to None from Resource ( which is the default) and change the Copy to "If Newer" or "Always" as shown below :

This worked for me to add an array within an array

this.setState(prevState => ({
    component: prevState.component.concat(new Array(['new', 'new']))
}));

There are two obvious issues with the set literal syntax:

my_set = {'foo', 'bar', 'baz'}

1. It's not available before Python 2.7

2. There's no way to express an empty set using that syntax (using {} creates an empty dict)

Those may or may not be important to you.

The section of the docs outlining this syntax is here.

android:inputType="textMultiLine"

This code line work for me. Add this code you edittext in your xml file.

O(n^2) is polynomial time. The polynomial is f(n) = n^2. On the other hand, O(2^n) is exponential time, where the exponential function implied is f(n) = 2^n. The difference is whether the function of n places n in the base of an exponentiation, or in the exponent itself.

Any exponential growth function will grow significantly faster (long term) than any polynomial function, so the distinction is relevant to the efficiency of an algorithm, especially for large values of n.

Ted Hopp answered this quite nicely. I have been using res/raw for my opengl texture and shader files. I was thinking about moving them to an assets directory to provide a hierarchical organization.

This thread convinced me not to. First, because I like the use of a unique resource id. Second because it's very simple to use InputStream/openRawResource or BitmapFactory to read in the file. Third because it's very useful to be able to use in a portable library.

if the possible values are integers you can bunch up cases. Otherwise, use ifs.

var api, tem;

switch(liCount){
    case 0:
    tem= 'start';
    break;
    case 1: case 2: case 3: case 4: case 5:
    tem= 'upload1Row';
    break;
    case 6: case 7: case 8: case 9: case 10:
    tem= 'upload2Rows';
    break;
    default:
    break;
}
if(tem) setLayoutState((tem);
api= $('#UploadList').data('jsp');
api.reinitialise();

I had the same problem on Samsung Galaxy Note 3, running CM 12.1. The issue for me was that i had

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="18"/>

and had to use it to take and store user photos. When I tried to load those same photos in ImageLoader i got the (Permission denied) error. The solution was to explicitly add

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

since the above permission only limits the write permission up to API version 18, and with it the read permission.

Mac OSX 10.7.5: I tried setting my proxy in the settings.xml file (as mentioned by posters above) in the /conf directory and also in the ~/.m2 directory, but still I got this error. I downloaded the latest version of Maven (3.1.1), and set my PATH variable to reflect the latest install, and it worked for me right off the shelf without any error.

you should you use following code

$configValue = Mage::getStoreConfig(
                   'sectionName/groupName/fieldName',
                   Mage::app()->getStore()
               ); 

Mage::app()->getStore() this will add store code in fetch values so that you can get correct configuration values for current store this will avoid incorrect store's values because magento is also use for multiple store/views so must add store code to fetch anything in magento.

if we have more then one store or multiple views configured then this will insure that we are getting values for current store

You can manage it with a double cast :

@SuppressWarnings("unchecked") Class<List<Foo>> cls = (Class<List<Foo>>)(Object)List.class

The port 8005 is used as service port. You can send a shutdown command (a configurable password) to that port. It will not "speak" HTTP, so you cannot use your browser to connect.

The default port for delivering web-content is 8080.

But there may be other applications listen to that port. So your tomcat may not start, if the port is not available.

You asked "How do you know, if tomcat server is installed on your PC?". The answer to that question is: You can't

You can't determine, if it is installed, because it may be only extracted from a ZIP archive or packaged within another application (Like JBoss AS (I think)).

It is an old article, but i want to warn people who will find it. Be careful with disabled attribute with got element by name. Strange but it seems not too work.

this do not work:

<script language="JavaScript">
function onChangeFullpageCheckbox() {    
$('name=img_size').attr("disabled",$("#fullpage").attr("checked"));
</script>

this work:

<script language="JavaScript">
function onChangeFullpageCheckbox() {    
$('#img_size').attr("disabled",$("#fullpage").attr("checked"));
</script>

Yes, i know that i better should use prop and not attr, but at least now prop will not work because of old version of jquery, and now i cant update it, dont ask why... html difference is only added id: ...

<select name="img_size" class="dropDown" id="img_size">
<option value="200">200px
</option><option value="300">300px
</option><option value="400">400px
</option><option value="500">500px
</option><option value="600" selected="">600px
</option><option value="800">800px
</option><option value="900">900px
</option><option value="1024">1024px
</option></select>

<input type="checkbox" name="fullpage" id="fullpage" onChange="onChangeFullpageCheckbox()" />

...

I have not found any mistakes in the script, and in the version with name, there was no errors in console. But ofcourse it can be my mistake in code

Seen on: Chrome 26 on Win 7 Pro

Sorry for bad grammar.

Or you can use JQuery - just add your input field to the class "phone" and put this in your script section:

$(".phone").keyup(function () {
        $(this).val($(this).val().replace(/^(\d{3})(\d{3})(\d)+$/, "($1)$2-$3"));

There is no error message but you can see that the phone number is not correctly formatted until you have entered all ten digits.

Assuming that you have a DHCP server running at your router I would use:

# /etc/network/interfaces
auto lo eth0
iface lo inet loopback

iface eth0 inet dhcp

After changing the file issue (as root):

/etc/init.d/networking restart

When using +, the speed decreases as the string's length increases, but when using concat, the speed is more stable, and the best option is using the StringBuilder class which has stable speed in order to do that.

I guess you can understand why. But the totally best way for creating long strings is using StringBuilder() and append(), either speed will be unacceptable.

Karl answered your search-path question, but as far as the "source of the files" goes, one thing to be aware of is that if you install the libfoo package and want to do some development with it (i.e., use its headers), you will also need to install libfoo-dev. The standard library header files are already in /usr/include, as you saw.

Note that some libraries with a lot of headers will install them to a subdirectory, e.g., /usr/include/openssl. To include one of those, just provide the path without the /usr/include part, for example:

#include <openssl/aes.h>

I'm going to improve the answer by supporting partitioned tables:

find partition scheme and partition key using below scritps:

declare @partition_scheme varchar(100) = (
select distinct ps.Name AS PartitionScheme
from sys.indexes i  
join sys.partitions p ON i.object_id=p.object_id AND i.index_id=p.index_id  
join sys.partition_schemes ps on ps.data_space_id = i.data_space_id  
where i.object_id = object_id('your table name')
)
print @partition_scheme

declare @partition_column varchar(100) = (
select c.name 
from  sys.tables          t
join  sys.indexes         i 
      on(i.object_id = t.object_id 
  and i.index_id < 2)
join  sys.index_columns  ic 
  on(ic.partition_ordinal > 0 
  and ic.index_id = i.index_id and ic.object_id = t.object_id)
join  sys.columns         c 
  on(c.object_id = ic.object_id 
  and c.column_id = ic.column_id)
where t.object_id  = object_id('your table name')
)
print @partition_column

then change the generation query by adding below line at the right place:

+ IIF(@partition_scheme is null, '', 'ON [' + @partition_scheme + ']([' + @partition_column + '])')

My objective was to create a new Django project from the command line in Ubuntu, like so:

django-admin.py startproject mysite

I have python2.7.5 installed. I got this error:

ImportError: No module named zlib

For hours I could not find a solution, until now!

Here is a link to the solution -

http://doc.biblissima-condorcet.fr/loris-setup-guide-ubuntu-debian

I followed and executed instruction in Section 1.1 and it is working perfectly! It is an easy solution.

var array: Int[][] = [[1,2,3],[4,5,6],[7,8,9]]

for first in array {
    for second in first {
        println("value \(second)")
    }
}

To achieve what you're looking for you need to initialize the array to the correct template and then loop to add the row and column arrays:

var NumColumns = 27
var NumRows = 52
var array = Array<Array<Int>>()
var value = 1

for column in 0..NumColumns {
    var columnArray = Array<Int>()
    for row in 0..NumRows {
        columnArray.append(value++)
    }
    array.append(columnArray)
}

println("array \(array)")

{!! Form::text('firstname', null !!}

@if($errors->has('firstname')) 
    {{ $errors->first('firstname') }} 
@endif

If you changed my.ini and restarted mysql and you still get this error please check your file path and replace "\" to "/". I solved my proplem after replacing.

Try this way:

This option was introduced in order to remove the need to deploy very large PIAs (Primary Interop Assemblies) for interop.

It simply embeds the managed bridging code used that allows you to talk to unmanaged assemblies, but instead of embedding it all it only creates the stuff you actually use in code.

Read more in Scott Hanselman's blog post about it and other VS improvements here.

As for whether it is advised or not, I'm not sure as I don't need to use this feature. A quick web search yields a few leads:

• Check your Embed Interop Types flag when doing Visual Studio extensibility work
• The Pain of deploying Primary Interop Assemblies

The only risk of turning them all to false is more deployment concerns with PIA files and a larger deployment if some of those files are large.

The SQL standard way to implement recursive queries, as implemented e.g. by IBM DB2 and SQL Server, is the WITH clause. See this article for one example of translating a CONNECT BY into a WITH (technically a recursive CTE) -- the example is for DB2 but I believe it will work on SQL Server as well.

Edit: apparently the original querant requires a specific example, here's one from the IBM site whose URL I already gave. Given a table:

CREATE TABLE emp(empid  INTEGER NOT NULL PRIMARY KEY,
                 name   VARCHAR(10),
                 salary DECIMAL(9, 2),
                 mgrid  INTEGER);

where mgrid references an employee's manager's empid, the task is, get the names of everybody who reports directly or indirectly to Joan. In Oracle, that's a simple CONNECT:

SELECT name 
  FROM emp
  START WITH name = 'Joan'
  CONNECT BY PRIOR empid = mgrid

In SQL Server, IBM DB2, or PostgreSQL 8.4 (as well as in the SQL standard, for what that's worth;-), the perfectly equivalent solution is instead a recursive query (more complex syntax, but, actually, even more power and flexibility):

WITH n(empid, name) AS 
   (SELECT empid, name 
    FROM emp
    WHERE name = 'Joan'
        UNION ALL
    SELECT nplus1.empid, nplus1.name 
    FROM emp as nplus1, n
    WHERE n.empid = nplus1.mgrid)
SELECT name FROM n

Oracle's START WITH clause becomes the first nested SELECT, the base case of the recursion, to be UNIONed with the recursive part which is just another SELECT.

SQL Server's specific flavor of WITH is of course documented on MSDN, which also gives guidelines and limitations for using this keyword, as well as several examples.

The obvious reason that people wanted assertNotEquals() was to compare builtins without having to convert them to full blown objects first:

Verbose example:

....
assertThat(1, not(equalTo(Integer.valueOf(winningBidderId))));
....

vs.

assertNotEqual(1, winningBidderId);

Sadly since Eclipse doesn't include JUnit 4.11 by default you must be verbose.

Caveat I don't think the '1' needs to be wrapped in an Integer.valueOf() but since I'm newly returned from .NET don't count on my correctness.

You can use the EXACT Function for exact string comparisons.

=IF(EXACT(A1, "ENG"), 1, 0)

Question: How can I open the href in the new window or tab with jQuery?

var url = $(this).attr('href').attr('target','_blank');

The problem was that you needed to add " ' ;" at the end.

As suggested earlier too, you can look at launch4j to create the executable for your JAR file. Also, there is something called "JExePack" that can put an .exe wrapper around your jar file so that you can redistribute it (note: the client would anyways need a JRE to run the program on his pc) Exes created with GCJ will not have this dependency but the process is a little more involved.

An important rule with respect to default parameter usage:
Default parameters should be specified at right most end, once you specify a default value parameter you cannot specify non default parameter again. ex:

int DoSomething(int x, int y = 10, int z) -----------> Not Allowed

int DoSomething(int x, int z, int y = 10) -----------> Allowed 

as of Jan 2017, unfortunately @Adi's answer, while it seems like it should work, does not. (Google's API key process is buggy)

you'll need to click "get a key" from this link: https://developers.google.com/maps/documentation/javascript/get-api-key

also I strongly recommend you don't ever choose "secure key" until you are ready to switch to production. I did http referrer restrictions on a key and afterwards was unable to get it working with localhost, even after disabling security for the key. I had to create a new key for it to work again.

Use the time.Now() and time.Format() functions (as time.LocalTime() doesn't exist anymore as of Go 1.0.3)

t := time.Now()
fmt.Println(t.Format("20060102150405"))

Online demo (with date fixed in the past in the playground, never mind)

From the documentation:

It is necessary to keep in mind that the browsers do not know how to correctly show this error.

I suspect this is what's happening, if you inspect the HTTP to-and-fro using tools such as Firebug or Live HTTP Headers (both Firefox extensions) you'll be able to see what's really going on.

Most debugger consoles support displaying objects directly. Just use

console.log(obj);

Depending on your debugger this most likely will display the object in the console as a collapsed tree. You can open the tree and inspect the object.

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f3" action="#" >
                <input id="edit3" type="submit" name="edit" value="Edit">
               </form>

   </tbody>

getJSON() will also parse the JSON for you after fetching, so from then on, you are working with a simple Javascript array ([] marks an array in JSON). The documentation also has examples on how to handle the fetched data.

You can get all the values in an array using a for loop:

$.getJSON("url_with_json_here", function(data){
    for (var i = 0, len = data.length; i < len; i++) {
        console.log(data[i]);
    }
});

Check your console to see the output (Chrome, Firefox/Firebug, IE).

jQuery also provides $.each() for iterations, so you could also do this:

$.getJSON("url_with_json_here", function(data){
    $.each(data, function (index, value) {
        console.log(value);
    });
});

I ran into the 'Expecting: ANY PRIVATE KEY' error when using openssl on Windows (Ubuntu Bash and Git Bash had the same issue).

The cause of the problem was that I'd saved the key and certificate files in Notepad using UTF8. Resaving both files in ANSI format solved the problem.

You can use:

SELECT COUNT(1) FROM MyTable WHERE ... 

or

WHERE [NOT] EXISTS 
( SELECT 1 FROM MyTable WHERE ... )

This will be more efficient than SELECT * since you're simply selecting the value 1 for each row, rather than all the fields.

There's also a subtle difference between COUNT(*) and COUNT(column name):

• COUNT(*) will count all rows, including nulls
• COUNT(column name) will only count non null occurrences of column name

You can skip the var declaration and the stringify. Otherwise, that will work just fine.

$.ajax({
    url: '/home/check',
    type: 'POST',
    data: {
        Address1: "423 Judy Road",
        Address2: "1001",
        City: "New York",
        State: "NY",
        ZipCode: "10301",
        Country: "USA"
    },
    contentType: 'application/json; charset=utf-8',
    success: function (data) {
        alert(data.success);
    },
    error: function () {
        alert("error");
    }
});

Not saying this is better, just another way:

$("#elem")[0].style.fontSize="20px";

As it happens I was just reading about this this morning on my way to work in Java Concurrency In Practice by Brian Goetz. Basically he says you should do one of three things

1. Propagate the InterruptedException - Declare your method to throw the checked InterruptedException so that your caller has to deal with it.

2. Restore the Interrupt - Sometimes you cannot throw InterruptedException. In these cases you should catch the InterruptedException and restore the interrupt status by calling the interrupt() method on the currentThread so the code higher up the call stack can see that an interrupt was issued, and quickly return from the method. Note: this is only applicable when your method has "try" or "best effort" semantics, i. e. nothing critical would happen if the method doesn't accomplish its goal. For example, log() or sendMetric() may be such method, or boolean tryTransferMoney(), but not void transferMoney(). See here for more details.

3. Ignore the interruption within method, but restore the status upon exit - e. g. via Guava's Uninterruptibles. Uninterruptibles take over the boilerplate code like in the Noncancelable Task example in JCIP § 7.1.3.

If you are using Grunt configuration, You need to do the following steps

Warning message in Jshint:

Solution:

1. Set the jshint options and map the .jshintrc.js file

2. Create the .jshintrc.js file in that file add the following code

{  
  "esversion": 6  
} 

After configured this, Run again It will skip the warning,

This one is much easie.

Threading.Thread.Sleep(3000)

Take your pick here.

Tkinter is in the Python stdlib.

In Java version prior to 1.7 you cannot cast object to primitive type

double d = (double) obj;

You can cast an Object to a Double just fine

Double d = (Double) obj;

Beware, it can throw a ClassCastException if your object isn't a Double

Getting image resouse as InputStream without context:

Class<? extends MyClass> aClass = MyClass.class;
URL r = aClass.getResource("/res/raw/test.png");
URLConnection urlConnection = r.openConnection();
return new BufferedInputStream(urlConnection.getInputStream());

If you need derectory tree for your files, it will also works (assets supports sub-dirs):

URL r = aClass.getResource("/assets/images/base/2.png");

When you include a string literal in a query, you can enclose the string in either single or double quotes; Access' database engine will accept either. So double quotes will avoid the problem with a string which contains a single quote.

SELECT * FROM tblStudents WHERE [name] Like "Daniel O'Neal";

If you want to keep the single quotes around your string, you can double up the single quote within it, as mentioned in other answers.

SELECT * FROM tblStudents WHERE [name] Like 'Daniel O''Neal';

Notice the square brackets surrounding name. I used the brackets to lessen the chance of confusing the database engine because name is a reserved word.

It's not clear why you're using the Like comparison in your query. Based on what you've shown, this should work instead.

SELECT * FROM tblStudents WHERE [name] = "Daniel O'Neal";

There are a few places you can do versioning in a REST API:

1. As noted, in the URI. This can be tractable and even esthetically pleasing if redirects and the like are used well.

2. In the Accepts: header, so the version is in the filetype. Like 'mp3' vs 'mp4'. This will also work, though IMO it works a bit less nicely than...

3. In the resource itself. Many file formats have their version numbers embedded in them, typically in the header; this allows newer software to 'just work' by understanding all existing versions of the filetype while older software can punt if an unsupported (newer) version is specified. In the context of a REST API, it means that your URIs never have to change, just your response to the particular version of data you were handed.

I can see reasons to use all three approaches:

1. if you like doing 'clean sweep' new APIs, or for major version changes where you want such an approach.
2. if you want the client to know before it does a PUT/POST whether it's going to work or not.
3. if it's okay if the client has to do its PUT/POST to find out if it's going to work.

It's not as simple as just omitting the return keyword. In Scala, if there is no return then the last expression is taken to be the return value. So, if the last expression is what you want to return, then you can omit the return keyword. But if what you want to return is not the last expression, then Scala will not know that you wanted to return it.

An example:

def f() = {
  if (something)
    "A"
  else
    "B"
}

Here the last expression of the function f is an if/else expression that evaluates to a String. Since there is no explicit return marked, Scala will infer that you wanted to return the result of this if/else expression: a String.

Now, if we add something after the if/else expression:

def f() = {
  if (something)
    "A"
  else
    "B"

  if (somethingElse)
    1
  else
    2
}

Now the last expression is an if/else expression that evaluates to an Int. So the return type of f will be Int. If we really wanted it to return the String, then we're in trouble because Scala has no idea that that's what we intended. Thus, we have to fix it by either storing the String to a variable and returning it after the second if/else expression, or by changing the order so that the String part happens last.

Finally, we can avoid the return keyword even with a nested if-else expression like yours:

def f() = {
  if(somethingFirst) {
    if (something)      // Last expression of `if` returns a String
     "A"
    else
     "B"
  }
  else {
    if (somethingElse)
      1
    else
      2

    "C"                // Last expression of `else` returns a String
  }

}

Deny takes precedence over Allow. Local rules take precedence over inherited rules. I have seen many solutions (including some answers shown here), but none of them takes into account whether rules are inherited or not. Therefore I suggest the following approach that considers rule inheritance (neatly wrapped into a class):

public class CurrentUserSecurity
{
    WindowsIdentity _currentUser;
    WindowsPrincipal _currentPrincipal;

    public CurrentUserSecurity()
    {
        _currentUser = WindowsIdentity.GetCurrent();
        _currentPrincipal = new WindowsPrincipal(_currentUser);
    }

    public bool HasAccess(DirectoryInfo directory, FileSystemRights right)
    {
        // Get the collection of authorization rules that apply to the directory.
        AuthorizationRuleCollection acl = directory.GetAccessControl()
            .GetAccessRules(true, true, typeof(SecurityIdentifier));
        return HasFileOrDirectoryAccess(right, acl);
    }

    public bool HasAccess(FileInfo file, FileSystemRights right)
    {
        // Get the collection of authorization rules that apply to the file.
        AuthorizationRuleCollection acl = file.GetAccessControl()
            .GetAccessRules(true, true, typeof(SecurityIdentifier));
        return HasFileOrDirectoryAccess(right, acl);
    }

    private bool HasFileOrDirectoryAccess(FileSystemRights right,
                                          AuthorizationRuleCollection acl)
    {
        bool allow = false;
        bool inheritedAllow = false;
        bool inheritedDeny = false;

        for (int i = 0; i < acl.Count; i++) {
            var currentRule = (FileSystemAccessRule)acl[i];
            // If the current rule applies to the current user.
            if (_currentUser.User.Equals(currentRule.IdentityReference) ||
                _currentPrincipal.IsInRole(
                                (SecurityIdentifier)currentRule.IdentityReference)) {

                if (currentRule.AccessControlType.Equals(AccessControlType.Deny)) {
                    if ((currentRule.FileSystemRights & right) == right) {
                        if (currentRule.IsInherited) {
                            inheritedDeny = true;
                        } else { // Non inherited "deny" takes overall precedence.
                            return false;
                        }
                    }
                } else if (currentRule.AccessControlType
                                                  .Equals(AccessControlType.Allow)) {
                    if ((currentRule.FileSystemRights & right) == right) {
                        if (currentRule.IsInherited) {
                            inheritedAllow = true;
                        } else {
                            allow = true;
                        }
                    }
                }
            }
        }

        if (allow) { // Non inherited "allow" takes precedence over inherited rules.
            return true;
        }
        return inheritedAllow && !inheritedDeny;
    }
}

However, I made the experience that this does not always work on remote computers as you will not always have the right to query the file access rights there. The solution in that case is to try; possibly even by just trying to create a temporary file, if you need to know the access right before working with the "real" files.

Ólafur forgot the surrogate key:

A surrogate key in a database is a unique identifier for either an entity in the modeled world or an object in the database. The surrogate key is not derived from application data.

Might be worth checking online for the errata section for your book.

There's an example of handling this exception here http://www.dba-oracle.com/sf_ora_01403_no_data_found.htm

const url = "http://www.example.com/1234"
const id = url.split('/').pop();

Try this, it is much easier

The output gives 1234

I'd like to add another use case for an internal struct/class and its usability. An inner struct is often used to declare a data only member of a class that packs together relevant information and as such we can enclose it all in a struct instead of loose data members lying around.

The inner struct/class is but a data only compartment, ie it has no functions (except maybe constructors).

#include <iostream>

class E
{
    // E functions..
public:
    struct X
    {
        int v;
        // X variables..
    } x;
    // E variables..
};

int main()
{
    E e;
    e.x.v = 9;
    std::cout << e.x.v << '\n';
    
    E e2{5};
    std::cout << e2.x.v << '\n';

    // You can instantiate an X outside E like so:
    //E::X xOut{24};
    //std::cout << xOut.v << '\n';
    // But you shouldn't want to in this scenario.
    // X is only a data member (containing other data members)
    // for use only inside the internal operations of E
    // just like the other E's data members
}

This practice is widely used in graphics, where the inner struct will be sent as a Constant Buffer to HLSL. But I find it neat and useful in many cases.

The -i flag probably doesn't work for you, because you followed an example for GNU sed while macOS uses BSD sed and they have a slightly different syntax.

All the other answers tell you how to correct the syntax to work with BSD sed. The alternative is to install GNU sed on your macOS with:

brew install gsed

and then use it instead of the sed version shipped with macOS (note the g prefix), e.g:

gsed -i 's/oldword/newword/' file1.txt

If you want GNU sed commands to be always portable to your macOS, you could prepend "gnubin" directory to your path, by adding something like this to your .bashrc/.zshrc file (run brew info gsed to see what exactly you need to do):

export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"

and from then on the GNU sed becomes your default sed and you can simply run:

sed -i 's/oldword/newword/' file1.txt

On Visual Studio 2017, the shortcut is: Ctrl+´,S.

This can works on most powershell versions:

(& { $MyInvocation.ScriptName; })

This can work for Scheduled Job

Get-ScheduledJob |? Name -Match 'JOBNAMETAG' |% Command

Have a look at the system.web.script.serialization namespace (i think you will need .Net 3.5)

This article clarifies the question for me and discusses other types of load balancer persistence.

Dave's Thoughts: Load balancer persistence (sticky sessions)

Minor note: Please consider that when you import from a default export, the naming is completely independent. This actually has an impact on refactorings.

Let's say you have a class Foo like this with a corresponding import:

export default class Foo { }

// The name 'Foo' could be anything, since it's just an
// Identifier for the default export
import Foo from './Foo'

Now if you refactor your Foo class to be Bar and also rename the file, most IDEs will NOT touch your import. So you will end up with this:

export default class Bar { }

// The name 'Foo' could be anything, since it's just an
// Identifier for the default export.
import Foo from './Bar'

Especially in TypeScript, I really appreciate named exports and the more reliable refactoring. The difference is just the lack of the default keyword and the curly braces. This btw also prevents you from making a typo in your import since you have type checking now.

export class Foo { }

//'Foo' needs to be the class name. The import will be refactored
//in case of a rename!
import { Foo } from './Foo'

The accepted answer works for me, but only after I realized I had to execute my code after the page was finished loading. In this situation inline script didn't work, I guess because #my_form wasn't done loading yet.

$(document).ready(function() {
  $("#my_form textarea").val('');
});

Numpy approach and timings against a list/array with 1.000.000 elements:

Timings:

In [10]: a.shape
Out[10]: (1000000,)

In [13]: len(lst)
Out[13]: 1000000

In [18]: %timeit a[a != 2]
100 loops, best of 3: 2.94 ms per loop

In [19]: %timeit [x for x in lst if x != 2]
10 loops, best of 3: 79.7 ms per loop

Conclusion: numpy is 27 times faster (on my notebook) compared to list comprehension approach

PS if you want to convert your regular Python list lst to numpy array:

arr = np.array(lst)

Setup:

import numpy as np
a = np.random.randint(0, 1000, 10**6)

In [10]: a.shape
Out[10]: (1000000,)

In [12]: lst = a.tolist()

In [13]: len(lst)
Out[13]: 1000000

Check:

In [14]: a[a != 2].shape
Out[14]: (998949,)

In [15]: len([x for x in lst if x != 2])
Out[15]: 998949

var Test = (from row in Dataset1.Tables[0].AsEnumerable()
            select row.Field<string>("attribute1_name") + row.Field<int>("attribute2_name")).Distinct();

A variable referencing an array is basically a pointer to its first element, so yes, you can legitimately return a pointer to an array, because thery're essentially the same thing. Check this out yourself:

#include <assert.h>

int main() {
  int a[] = {1, 2, 3, 4, 5}; 

  int* pArr = a;
  int* pFirstElem = &(a[0]);

  assert(a == pArr);
  assert(a == pFirstElem);

  return 0;
}

This also means that passing an array to a function should be done via pointer (and not via int in[5]), and possibly along with the length of the array:

int* test(int* in, int len) {
    int* out = in;
    return out;
}

That said, you're right that using pointers (without fully understanding them) is pretty dangerous. For example, referencing an array that was allocated on the stack and went out of scope yields undefined behavior:

#include <iostream>

using namespace std;

int main() {
  int* pArr = 0;
  {
    int a[] = {1, 2, 3, 4, 5};
    pArr = a; // or test(a) if you wish
  }
  // a[] went out of scope here, but pArr holds a pointer to it

  // all bets are off, this can output "1", output 1st chapter
  // of "Romeo and Juliet", crash the program or destroy the
  // universe
  cout << pArr[0] << endl; // WRONG!

  return 0;
}

So if you don't feel competent enough, just use std::vector.

[answer to the updated question]

The correct way to write your test function is either this:

void test(int* a, int* b, int* c, int len) {
  for (int i = 0; i < len; ++i) c[i] = a[i] + b[i];
}
...
int main() {
   int a[5] = {...}, b[5] = {...}, c[5] = {};
   test(a, b, c, 5);
   // c now holds the result
}

Or this (using std::vector):

#include <vector>

vector<int> test(const vector<int>& a, const vector<int>& b) {
  vector<int> result(a.size());
  for (int i = 0; i < a.size(); ++i) {
    result[i] = a[i] + b[i];
  }
  return result; // copy will be elided
}

You can use getComputedStyle().

var element = document.getElementById('image_1'),
    style = window.getComputedStyle(element),
    top = style.getPropertyValue('top');

jsFiddle.

From Django 2.0 on_delete is required:

user = models.OneToOneField(User, on_delete=models.CASCADE)

It will delete the child table data if the User is deleted. For more details check the Django documentation.

In case it helps someone, if your variables have hyphens in them, you may see this error since hyphens are not allowed in variable names in Python and are used as subtraction operators.

Example:

my-variable = 5   # would result in 'SyntaxError: can't assign to operator'

Please refer to this for the example .The main point is to use the groupProperty() , and the related aggregate functions provided by the Projections class.

For example :

SELECT column_name, max(column_name) , min (column_name) , count(column_name)
FROM table_name
WHERE column_name > xxxxx
GROUP BY column_name

Its equivalent criteria object is :

List result = session.createCriteria(SomeTable.class)       
                    .add(Restrictions.ge("someColumn", xxxxx))      
                    .setProjection(Projections.projectionList()
                            .add(Projections.groupProperty("someColumn"))
                            .add(Projections.max("someColumn"))
                            .add(Projections.min("someColumn"))
                            .add(Projections.count("someColumn"))           
                    ).list();

To Change Button title:

[mybtn setTitle:@"My Button" forState:UIControlStateNormal];
[mybtn setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];

For Disable:

[mybtn setEnabled:NO];

var bottom = $('#bottom').position().top + $('#bottom').height();

As you mentioned, prompt works for browsers all the way back to IE:

var answer = prompt('question', 'defaultAnswer');

For Node.js > v7.6, you can use console-read-write, which is a wrapper around the low-level readline module:

const io = require('console-read-write');

async function main() {
  // Simple readline scenario
  io.write('I will echo whatever you write!');
  io.write(await io.read());

  // Simple question scenario
  io.write(`hello ${await io.ask('Who are you?')}!`);

  // Since you are not blocking the IO, you can go wild with while loops!
  let saidHi = false;
  while (!saidHi) {
    io.write('Say hi or I will repeat...');
    saidHi = await io.read() === 'hi';
  }

  io.write('Thanks! Now you may leave.');
}

main();
// I will echo whatever you write!
// > ok
// ok
// Who are you? someone
// hello someone!
// Say hi or I will repeat...
// > no
// Say hi or I will repeat...
// > ok
// Say hi or I will repeat...
// > hi
// Thanks! Now you may leave.

I doubt we'd ever use the word "ECMAScript" if not for the fact that the name "JavaScript" is owned by Sun. For all intents and purposes, the language is JavaScript. You don't go to the bookstore looking for ECMAScript books, do you?

It's a bit too simple to say that "JavaScript" is the implementation. JScript is Microsoft's implementation.

Do you have xml_grep installed? It's a perl based utility standard on some distributions (it came pre-installed on my CentOS system). Rather than giving it a regular expression, you give it an xpath expression.

If you can't hold all the items in memory at once, this problem becomes much harder. The heap solution requires you to hold all the elements in memory at once. This is not possible in most real world applications of this problem.

Instead, as you see numbers, keep track of the count of the number of times you see each integer. Assuming 4 byte integers, that's 2^32 buckets, or at most 2^33 integers (key and count for each int), which is 2^35 bytes or 32GB. It will likely be much less than this because you don't need to store the key or count for those entries that are 0 (ie. like a defaultdict in python). This takes constant time to insert each new integer.

Then at any point, to find the median, just use the counts to determine which integer is the middle element. This takes constant time (albeit a large constant, but constant nonetheless).

Since Python is interpreted and run in C, it is possible to set colors without a module.

You can define a class for colors like this:

class color:
   PURPLE = '\033[1;35;48m'
   CYAN = '\033[1;36;48m'
   BOLD = '\033[1;37;48m'
   BLUE = '\033[1;34;48m'
   GREEN = '\033[1;32;48m'
   YELLOW = '\033[1;33;48m'
   RED = '\033[1;31;48m'
   BLACK = '\033[1;30;48m'
   UNDERLINE = '\033[4;37;48m'
   END = '\033[1;37;0m'

When writing code, you can simply write:

print(color.BLUE + "hello friends" + color.END)

Note that the color you choose will have to be capitalized like your class definition, and that these are color choices that I personally find satisfying. For a fuller array of color choices and, indeed, background choices as well, please see: https://gist.github.com/RabaDabaDoba/145049536f815903c79944599c6f952a.

This is code for C, but can easily be adapted to Python once you realize how the code is written.

Take BLUE for example, since that is what you are wanting to display.

BLUE = '033[1;37;48m'

\033 tells Python to break and pay attention to the following formatting.

1 informs the code to be bold. (I prefer 1 to 0 because it pops more.)

34 is the actual color code. It chooses blue.

48m is the background color. 48m is the same shade as the console window, so it seems there is no background.

This little bit different idea. But it will useful to you. I have used sub query to inside the linq main query.

Problem:

Let say we have document table. Schema as follows schema : document(name,version,auther,modifieddate) composite Keys : name,version

So we need to get latest versions of all documents.

soloution

 var result = (from t in Context.document
                          where ((from tt in Context.document where t.Name == tt.Name
                                orderby tt.Version descending select new {Vesion=tt.Version}).FirstOrDefault()).Vesion.Contains(t.Version)
                          select t).ToList();

You will need to create custom form controls (as directives) for the phone number and the credit card. See section "Implementing custom form control (using ngModel)" on the forms page.

As Narretz already mentioned, Angular-ui's Mask directive should help get you started.

I make some examples for your reference.

  DEFINE: &id_define !ref [*id_SUNG]  # you can use config['CREATE_FONT_PICTURE']['DEFINE'][name, work_dir, ... font_pixel]
  AUTO_INIT:
    basename_suffix: !dict_ref [*id_define, name, !product [5, 3, 2]]  # SUNG30

# ? This is not correct.
# basename_suffix: !dict_ref [*id_define, name, !product [5, 3, 2]]  # It will build by Deep-level. id_define is Deep-level: 2. So you must put it after 2. otherwise, it can't refer to the correct value.

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.

Design patterns aren't trivially reusable solutions.

Design patterns are reusable, by definition. They're patterns you detect in other good solutions.

A pattern is not trivially reusable. You can implement your down design following the pattern however.

Relational design patters include things like:

1. One-to-Many relationships (master-detail, parent-child) relationships using a foreign key.

2. Many-to-Many relationships with a bridge table.

3. Optional one-to-one relationships managed with NULLs in the FK column.

4. Star-Schema: Dimension and Fact, OLAP design.

5. Fully normalized OLTP design.

6. Multiple indexed search columns in a dimension.

7. "Lookup table" that contains PK, description and code value(s) used by one or more applications. Why have code? I don't know, but when they have to be used, this is a way to manage the codes.

8. Uni-table. [Some call this an anti-pattern; it's a pattern, sometimes it's bad, sometimes it's good.] This is a table with lots of pre-joined stuff that violates second and third normal form.

9. Array table. This is a table that violates first normal form by having an array or sequence of values in the columns.

10. Mixed-use database. This is a database normalized for transaction processing but with lots of extra indexes for reporting and analysis. It's an anti-pattern -- don't do this. People do it anyway, so it's still a pattern.

Most folks who design databases can easily rattle off a half-dozen "It's another one of those"; these are design patterns that they use on a regular basis.

And this doesn't include administrative and operational patterns of use and management.

you have to iterate gridview Rows

for (int count = 0; count < grd.Rows.Count; count++)
{
    if (((CheckBox)grd.Rows[count].FindControl("yourCheckboxID")).Checked)
    {     
      ((Label)grd.Rows[count].FindControl("labelID")).Text
    }
}

I used the solution below and it worked for me (mixing traditional javascript with jQuery)

$("#myformId").submit(function() {
    comand="window.document."+$(this).attr('name')+".reset()";
    setTimeout("eval(comando)",4000);
})

You need to do this:

var scope = {
     splitterStyle: {
         height: 100
     }
};

And then apply this styling to the required elements:

<div id="horizontal" style={splitterStyle}>

In your code you are doing this (which is incorrect):

<div id="horizontal" style={height}>

Where height = 100.

If you want to change your 'sa' password with SQL Server Management Studio, here are the steps:

1. Login using Windows Authentication and ".\SQLExpress" as Server Name

2. Change server authentication mode - Right click on root, choose Properties, from Security tab select "SQL Server and Windows Authentication mode", click OK

3. Set sa password - Navigate to Security > Logins > sa, right click on it, choose Properties, from General tab set the Password (don't close the window)

4. Grant permission - Go to Status tab, make sure the Grant and Enabled radiobuttons are chosen, click OK

5. Restart SQLEXPRESS service from your local services (Window+R > services.msc)

In my case my column was a datetime it kept giving me all records. What I did is to include time, see below example

SELECT * FROM my_table where start_date > '2011-01-01 01:01:01';

For any Single File Component users, here is how I set up global variable(s)

1. Assuming you are using Vue-Cli's webpack template

2. Declare your variable(s) in somewhere variable.js

   const shallWeUseVuex = false;
   

3. Export it in variable.js

   module.exports = { shallWeUseVuex : shallWeUseVuex };
   

4. Require and assign it in your vue file

   export default {
       data() {
           return {
               shallWeUseVuex: require('../../variable.js')
           };
       }
   }

When you're doing this

var model = @Html.Raw(Json.Encode(Model));

You're probably getting a JSON string, and not a JavaScript object.

You need to parse it in to an object:

var model = JSON.parse(model); //or $.parseJSON() since if jQuery is included
console.log(model.Sections);

cin.clear();
fflush(stdin);

This was the only thing that worked for me when reading from console. In every other case it would either read indefinitely due to lack of \n, or something would remain in the buffer.

EDIT: I found out that the previous solution made things worse. THIS one however, works:

cin.getline(temp, STRLEN);
if (cin.fail()) {
    cin.clear();
    cin.ignore(numeric_limits<streamsize>::max(), '\n');
}

You can also set up a mime type for application/JavaScript to run as PHP, .NET, Java, or whatever language you're using. I've done this for dynamic CSS files in the past.

Perhaps the most beginner-friendly way to compile a JAR from your Java code is to use an IDE (integrated development environment; essentially just user-friendly software for development) like Netbeans or Eclipse.

• Install and set-up an IDE. Here is the latest version of Eclipse.
• Create a project in your IDE and put your Java files inside of the project folder.
• Select the project in the IDE and export the project as a JAR. Double check that the appropriate java files are selected when exporting.

You can always do this all very easily with the command line. Make sure that you are in the same directory as the files targeted before executing a command such as this:

javac YourApp.java
jar -cf YourJar.jar YourApp.class

...changing "YourApp" and "YourJar" to the proper names of your files, respectively.

for logical && both the parameters must be true , then it ll be entered in if {} clock otherwise it ll execute else {}. for logical || one of parameter or condition is true is sufficient to execute if {}.

if( (A) && (B) ){
     //if A and B both are true
}else{
}
if( (A) ||(B) ){
     //if A or B is true 
}else{
}

If you want to redirect on url instead of activity from your adapter class then pass context of with startactivity.

btnInstall.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(Intent.ACTION_VIEW, Uri.parse(link));
                intent.setData(Uri.parse(link));
                context.startActivity(intent);
            }
        });

Try this one:

if(FALSE !== ($key = array_search($_GET['name'],$_SESSION['name'])))
{
    unset($_SESSION['name'][$key]);
}

Due to this article is a good SEO site, so I suggest to use build-in function "mb_convert_variables" to solve this problem. It works with simple syntax.

mb_convert_variables('utf-8', 'original encode', array/object)

If you want to use straight PowerShell check out the below code.

$content = Get-Content C:\Users\You\Documents\test.txt
foreach ($line in $content)
{
    Write-Host $line
}

Functionality is supposed to be broken in jQuery 1.5.

Since jQuery 1.5.1 you should use xhrFields param.

$.ajaxSetup({
    type: "POST",
    data: {},
    dataType: 'json',
    xhrFields: {
       withCredentials: true
    },
    crossDomain: true
});

Docs: http://api.jquery.com/jQuery.ajax/

Reported bug: http://bugs.jquery.com/ticket/8146

You use separator when you are building a file path. So in unix the separator is /. So if you wanted to build the unix path /var/temp you would do it like this:

String path = File.separator + "var"+ File.separator + "temp"

You use the pathSeparator when you are dealing with a list of files like in a classpath. For example, if your app took a list of jars as argument the standard way to format that list on unix is: /path/to/jar1.jar:/path/to/jar2.jar:/path/to/jar3.jar

So given a list of files you would do something like this:

String listOfFiles = ...
String[] filePaths = listOfFiles.split(File.pathSeparator);

I resolved it like this:

<% @user.errors.each do |attr, msg| %>
  <li>
    <%= @user.errors.full_messages_for(attr).first if @user.errors[attr].first == msg %>
  </li>
<% end %>

This way you are using the locales for the error messages.

Personally more than anything I would change the logic, or look at the business rules to see if they dictate any potential naming.

Since, the actual condition that toggles the boolean is actually the act of being "last". I would say that switching the logic, and naming it "IsLastItem" or similar would be a more preferred method.

Try to edit your my.cf and comment the original sql_mode and add sql_mode = "".

vi /etc/mysql/my.cnf

sql_mode = ""

save and quit...

service mysql restart

This issue could be because adb incompatibility with the newest version of the platform SDK.

Try the following:

1. If you are using Genymotion, manually set the Android SDK within Genymotion settings to your sdk path. Go to Genymotion -> settings -> ADB -> Use custom SDK Tools -> Browse and ender your local SDK path.

2. If you haverecently updated your platform-tools plugin version, revert back to 23.0.1.

Its a bug within ADB, one of the above must most likely be your solution.

For a project this size, you should stop writing pure JavaScript and turn to some of the libraries available. I'd recommend jQuery (http://jquery.com/), which allows you to select elements by css-selectors, which I recon should speed up your development quite a bit.

Example of your code then becomes;

function AddtoCart() {
  var len = $("#Items tr").length, $row, $inp1, $inp2, $cells;

  $row = $("#Items td:first").clone(true);
  $cells = $row.find("td");

  $cells.get(0).html( len );

  $inp1 = $cells.get(1).find("input:first");
  $inp1.attr("id", $inp1.attr("id") + len).val("");

  $inp2 = $cells.get(2).find("input:first");
  $inp2.attr("id", $inp2.attr("id") + len).val("");

  $("#Items").append($row);
    }

I can see that you might not understand that code yet, but take a look at jQuery, it's easy to learn and will make this development way faster.

I would use the libraries already created specifically for js shopping carts if I were you though.

To your problem; If i look at your jsFiddle, it doesn't even seem like you have defined a table with the id Items? Maybe that's why it doesn't work?

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

You could use SwiftString (https://github.com/amayne/SwiftString) to do this.

"".join(["string1", "string2", "string3"]) // "string1string2string"
" ".join(["hello", "world"]) // "hello world"

The simplest and the most efficient way is to use an uber plugin like this:

          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <finalName>uber-${project.artifactId}-${project.version}</finalName>
            </configuration>
        </plugin>

You will have de-normalized all in one JAR file.

There is an onpaste event that works in modern day browsers. You can access the pasted data using the getData function on the clipboardData object.

$("#textareaid").bind("paste", function(e){
    // access the clipboard using the api
    var pastedData = e.originalEvent.clipboardData.getData('text');
    alert(pastedData);
} );

Note that bind and unbind are deprecated as of jQuery 3. The preferred call is to on.

All modern day browsers support the Clipboard API.

See also: In Jquery How to handle paste?

You can compare the returned value of fp.tell() before and after calling the read method. If they return the same value, fp is at eof.

Furthermore, I don't think your example code actually works. The read method to my knowledge never returns None, but it does return an empty string on eof.

try this:

HTML:

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
  <div class="item">5</div>
</div>

CSS:

.container {
  width: 200px;
  height: 100px;
  display: flex;
  overflow-x: auto;
}

.item {
  width: 100px;
  flex-shrink: 0;
  height: 100px;
}

The white-space: nowrap; property dont let you wrap text. Just see here for an example: https://codepen.io/oezkany/pen/YoVgYK

You can try VbsEdit. Get the latest version from Adersoft's VbsEdit http://www.vbsedit.com its a small download but it is a powerful tool to create and edit vbs files and convert them into executables without unpacking to temporary folder. (unless you get an old version like version 4.x.x.x) I've been using this program since 2008, and it's free to evaluate forever but comes with a reminder to activate and each time you Start your script from the vbsedit window you will have to wait a few seconds, Or you could purchase it for $60 to remove those minor annoyances.
Unlike ScriptCryptor, the converted exe won't have any limitations if you are still evaluating, it will run without any unwanted additional windows.

Or create a function that creates an element including attributes from parameters

function elemCreate(elType){
  var element = document.createElement(elType);
  if (arguments.length>1){
    var props = [].slice.call(arguments,1), key = props.shift();
    while (key){ 
      element.setAttribute(key,props.shift());
      key = props.shift();
    }
  }
  return element;
}
// usage
var img = elemCreate('img',
            'width','100',
            'height','100',
            'src','http://example.com/something.jpeg');

FYI: height/width='100%' would not work using attributes. For a height/width of 100% you need the elements style.height/style.width

Only to supplement:

1. dir() is the most powerful/fundamental tool. (Most recommended)

2. Solutions other than dir() merely provide their way of dealing the output of dir().

   Listing 2nd level attributes or not, it is important to do the sifting by yourself, because sometimes you may want to sift out internal vars with leading underscores __, but sometimes you may well need the __doc__ doc-string.

3. __dir__() and dir() returns identical content.
4. __dict__ and dir() are different. __dict__ returns incomplete content.

5. IMPORTANT: __dir__() can be sometimes overwritten with a function, value or type, by the author for whatever purpose.

   Here is an example:

It will have already gone back before it executes the reload.

You would be better off to replace:

window.history.back();
location.reload(); 

with:

window.location.replace("pagehere.html");

I would not recomend you to use document.write as others suggest, because if you will open such window twice your HTML will be duplicated 2 times (or more).

Use innerHTML instead

var win = window.open("", "Title", "toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=780,height=200,top="+(screen.height-400)+",left="+(screen.width-840));
win.document.body.innerHTML = "HTML";

You just need to create your own class inherited from parent. Place an ImageView on that, and on the mousedown and mouse up events just change the images of the ImageView.

public class ImageButton extends Parent {

    private static final Image NORMAL_IMAGE = ...;
    private static final Image PRESSED_IMAGE = ...;

    private final ImageView iv;

    public ImageButton() {
        this.iv = new ImageView(NORMAL_IMAGE);
        this.getChildren().add(this.iv);

        this.iv.setOnMousePressed(new EventHandler<MouseEvent>() {

            public void handle(MouseEvent evt) {
                iv.setImage(PRESSED_IMAGE);
            }

        });

        // TODO other event handlers like mouse up

    } 

}

You could use a Bat to Exe converter from here:

http://www.f2ko.de/en/b2e.php

This will convert your batch file to an executable, then you can set the icon for the converted file.

The new line character is \n, like so:

echo __("Thanks for your email.\n<br />\n<br />Your order's details are below:", 'jigoshop');

All this is about cultures. If you have any other culture than "US English" (and also as good manners of development), you should use something like this:

var d = Convert.ToDecimal("1.2345", new CultureInfo("en-US"));
// (or 1,2345 with your local culture, for instance)

(obviously, you should replace the "en-US" with the culture of your number local culture)

the same way, if you want to do ToString()

d.ToString(new CultureInfo("en-US"));

If what you really want is to avoid multiple form submissions, and not just prevent double click, using jQuery one() on a button's click event can be problematic if there's client-side validation (such as text fields marked as required). That's because click triggers client-side validation, and if the validation fails you cannot use the button again. To avoid this, one() can still be used directly on the form's submit event. This is the cleanest jQuery-based solution I found for that:

<script type="text/javascript">
$("#my-signup-form").one("submit", function() {
    // Just disable the button.
    // There will be only one form submission.
    $("#my-signup-btn").prop("disabled", true);
});
</script>

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

For me, I always choose non-thread safe version because I always use nginx, or run PHP from the command line.

The non-thread safe version should be used if you install PHP as a CGI binary, command line interface or other environment where only a single thread is used.

A thread-safe version should be used if you install PHP as an Apache module in a worker MPM (multi-processing model) or other environment where multiple PHP threads run concurrently.

Setting my RequestOperationManager Response Serializer to HTTPResponseSerializer fixed the issue.

Objective-C

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

Swift

manager.responseSerializer = AFHTTPResponseSerializer()

Making this change means I don't need to add acceptableContentTypes to every request I make.

I would go with

i = np.min(np.where(V >= x))

where V is vector (1d array), x is the value and i is the resulting index.

My solution with Angular 4.0.1: Just showing the UI for required CVC input - where the CVC must be exactly 3 digits:

    <form #paymentCardForm="ngForm">         
...
        <md-input-container align="start">
            <input #cvc2="ngModel" mdInput type="text" id="cvc2" name="cvc2" minlength="3" maxlength="3" placeholder="CVC" [(ngModel)]="paymentCard.cvc2" [disabled]="isBusy" pattern="\d{3}" required />
            <md-hint *ngIf="cvc2.errors && (cvc2.touched || submitted)" class="validation-result">
                <span [hidden]="!cvc2.errors.required && cvc2.dirty">
                    CVC is required.
                </span>
                <span [hidden]="!cvc2.errors.minlength && !cvc2.errors.maxlength && !cvc2.errors.pattern">
                    CVC must be 3 numbers.
                </span>
            </md-hint>
        </md-input-container>
...
<button type="submit" md-raised-button color="primary" (click)="confirm($event, paymentCardForm.value)" [disabled]="isBusy || !paymentCardForm.valid">Confirm</button>
</form>

Edit: Solution for L5.2+

There's a better and more straightforward solution.

Use Storage::url($filename) to get the full path/URL of a given file. Note that you need to set S3 as your storage filesystem in config/filesystems.php: 'default' => 's3'

Of course, you can also do Storage::disk('s3')->url($filename) in the same way.

As you can see in config/filesystems.php there's also a parameter 'cloud' => 's3' defined, that refers to the Cloud filesystem. In case you want to mantain the storage folder in the local server but retrieve/store some files in the cloud use Storage::cloud(), which also has the same filesystem methods, i.e. Storage::cloud()->url($filename).

The Laravel documentation doesn't mention this method, but if you want to know more about it you can check its source code here.

You shouldn't search through that array, but use database capabilities for this
Suppose you're passing username through GET form:

if (isset($_GET['search'])) {
  $search = mysql_real_escape_string($_GET['search']);
  $sql = "SELECT * FROM users WHERE username = '$search'";
  $res = mysql_query($sql) or trigger_error(mysql_error().$sql);
  $row = mysql_fetch_assoc($res);
  if ($row){
    print_r($row); //do whatever you want with found info
  }
}

Try this:

jquery

    $('#save-source').click(function (e) {
        e.preventDefault();
        var source = {
            'ID': 0,
            //'ProductID': $('#ID').val(),
            'PartNumber': $('#part-number').val(),
            //'VendorID': $('#Vendors').val()
        }
        $.ajax({
            type: "POST",
            dataType: "json",
            url: "/api/PartSourceAPI",
            data: source,
            success: function (data) {
                alert(data);
            },
            error: function (error) {
                jsonValue = jQuery.parseJSON(error.responseText);
                //jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
            }
        });
    });

Controller

    public string Post(PartSourceModel model)
    {
        return model.PartNumber;
    }

View

<label>Part Number</label>
<input type="text" id="part-number" name="part-number" />

<input type="submit" id="save-source" name="save-source" value="Add" />

Now when you click 'Add' after you fill out the text box, the controller will spit back out what you wrote in the PartNumber box in an alert.

Try with below code:

$('.close').click(function(){
var checkstr =  confirm('are you sure you want to delete this?');
if(checkstr == true){
  // do your code
}else{
return false;
}
});

OR

function deleteItem(){
    var checkstr =  confirm('are you sure you want to delete this?');
    if(checkstr == true){
      // do your code
    }else{
    return false;
    }
  }

This may work for you..

Thanks.

First this solution is applicable to those who are facing the same issue during deployment on heroku server, I was facing same issue.

To deploy, there is a mandatory step which is to add django_heroku.settings(locals()) in settings.py file.

Changes: When I changed the above line to django_heroku.settings(locals(), databases=False), it worked flawlessly.

As Python 3.0 and 3.1 are EOL'ed and no one uses them, you can and should use str.format_map(mapping) (Python 3.2+):

Similar to str.format(**mapping), except that mapping is used directly and not copied to a dict. This is useful if for example mapping is a dict subclass.

What this means is that you can use for example a defaultdict that would set (and return) a default value for keys that are missing:

>>> from collections import defaultdict
>>> vals = defaultdict(lambda: '<unset>', {'bar': 'baz'})
>>> 'foo is {foo} and bar is {bar}'.format_map(vals)
'foo is <unset> and bar is baz'

Even if the mapping provided is a dict, not a subclass, this would probably still be slightly faster.

The difference is not big though, given

>>> d = dict(foo='x', bar='y', baz='z')

then

>>> 'foo is {foo}, bar is {bar} and baz is {baz}'.format_map(d)

is about 10 ns (2 %) faster than

>>> 'foo is {foo}, bar is {bar} and baz is {baz}'.format(**d)

on my Python 3.4.3. The difference would probably be larger as more keys are in the dictionary, and

Note that the format language is much more flexible than that though; they can contain indexed expressions, attribute accesses and so on, so you can format a whole object, or 2 of them:

>>> p1 = {'latitude':41.123,'longitude':71.091}
>>> p2 = {'latitude':56.456,'longitude':23.456}
>>> '{0[latitude]} {0[longitude]} - {1[latitude]} {1[longitude]}'.format(p1, p2)
'41.123 71.091 - 56.456 23.456'

Starting from 3.6 you can use the interpolated strings too:

>>> f'lat:{p1["latitude"]} lng:{p1["longitude"]}'
'lat:41.123 lng:71.091'

You just need to remember to use the other quote characters within the nested quotes. Another upside of this approach is that it is much faster than calling a formatting method.

If you want one line:

list_of_dict = [{} for i in range(list_len)]

From http://api.jquery.com/jQuery/

Selector Context By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function. For example, to do a search within an event handler, the search can be restricted like so:

$( "div.foo" ).click(function() { 
   $( "span", this ).addClass( "bar" );
});

When the search for the span selector is restricted to the context of this, only spans within the clicked element will get the additional class.

So for your example I would suggest something like:

$("div", ".container").each(function(){
     //do whatever
 });

All you need to do is just to add:

width: '65%',

Use React Native Hyperlink (Native <A> tag):

Install:

npm i react-native-a

import:

import A from 'react-native-a'

Usage:

1. <A>Example.com</A>
2. <A href="example.com">Example</A>
3. <A href="https://example.com">Example</A>
4. <A href="example.com" style={{fontWeight: 'bold'}}>Example</A>

JUnit since 5.5 allows @TestMethodOrder(OrderAnnotation.class) on class and @Order(1) on test-methods.

JUnit old versions allow test methods run ordering using class annotations:

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
@FixMethodOrder(MethodSorters.JVM)
@FixMethodOrder(MethodSorters.DEFAULT)

By default test methods are run in alphabetical order. So, to set specific methods order you can name them like:

a_TestWorkUnit_WithCertainState_ShouldDoSomething b_TestWorkUnit_WithCertainState_ShouldDoSomething c_TestWorkUnit_WithCertainState_ShouldDoSomething

Or

_1_TestWorkUnit_WithCertainState_ShouldDoSomething _2_TestWorkUnit_WithCertainState_ShouldDoSomething _3_TestWorkUnit_WithCertainState_ShouldDoSomething

You can find examples here.

When installing a tool globally it's to be used by a user as a command line utility anywhere, including outside of node projects. Global installs for a node project are bad because they make deployment more difficult.

npm 5.2+

The npx utility bundled with npm 5.2 solves this problem. With it you can invoke locally installed utilities like globally installed utilities (but you must begin the command with npx). For example, if you want to invoke a locally installed eslint, you can do:

npx eslint .

npm < 5.2

When used in a script field of your package.json, npm searches node_modules for the tool as well as globally installed modules, so the local install is sufficient.

So, if you are happy with (in your package.json):

"devDependencies": {
    "gulp": "3.5.2"
}
"scripts": {
    "test": "gulp test"
}

etc. and running with npm run test then you shouldn't need the global install at all.

Both methods are useful for getting people set up with your project since sudo isn't needed. It also means that gulp will be updated when the version is bumped in the package.json, so everyone will be using the same version of gulp when developing with your project.

Addendum:

It appears that gulp has some unusual behaviour when used globally. When used as a global install, gulp looks for a locally installed gulp to pass control to. Therefore a gulp global install requires a gulp local install to work. The answer above still stands though. Local installs are always preferable to global installs.

basically i use this in one of our apps: we want to overlay a playicon over a frame of a video:

Image playbutton;
try
{
    playbutton = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

Image frame;
try
{
    frame = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

using (frame)
{
    using (var bitmap = new Bitmap(width, height))
    {
        using (var canvas = Graphics.FromImage(bitmap))
        {
            canvas.InterpolationMode = InterpolationMode.HighQualityBicubic;
            canvas.DrawImage(frame,
                             new Rectangle(0,
                                           0,
                                           width,
                                           height),
                             new Rectangle(0,
                                           0,
                                           frame.Width,
                                           frame.Height),
                             GraphicsUnit.Pixel);
            canvas.DrawImage(playbutton,
                             (bitmap.Width / 2) - (playbutton.Width / 2),
                             (bitmap.Height / 2) - (playbutton.Height / 2));
            canvas.Save();
        }
        try
        {
            bitmap.Save(/*somekindofpath*/,
                        System.Drawing.Imaging.ImageFormat.Jpeg);
        }
        catch (Exception ex) { }
    }
}

I agree with pjco. The best way is the official method explained in Support Library Setup in the tutorial at developer.android.com.

Then, in the Eclipse "package explorer", expand your main project and delete android-support-v4.jar from the "libs" folder (as Pratik Butani suggested).

This worked for me.

I use this command:

ls -1 | xargs readlink -f

If you use Maven:

poi => poi-ooxml in artifactId

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.12</version>
    </dependency>

Copied from MSDN:

At compile time, verbatim strings are converted to ordinary strings with all the same escape sequences. Therefore, if you view a verbatim string in the debugger watch window, you will see the escape characters that were added by the compiler, not the verbatim version from your source code. For example, the verbatim string @"C:\files.txt" will appear in the watch window as "C:\\files.txt".

I am very surprised that no one mentioned the infamous "lost wakeup" problem (google it).

Basically:

1. if you have multiple threads waiting on a same condition and,
2. multiple threads that can make you transition from state A to state B and,
3. multiple threads that can make you transition from state B to state A (usually the same threads as in 1.) and,
4. transitioning from state A to B should notify threads in 1.

THEN you should use notifyAll unless you have provable guarantees that lost wakeups are impossible.

A common example is a concurrent FIFO queue where: multiple enqueuers (1. and 3. above) can transition your queue from empty to non-empty multiple dequeuers (2. above) can wait for the condition "the queue is not empty" empty -> non-empty should notify dequeuers

You can easily write an interleaving of operations in which, starting from an empty queue, 2 enqueuers and 2 dequeuers interact and 1 enqueuer will remain sleeping.

This is a problem arguably comparable with the deadlock problem.

There is no automatic addition of app.config file when you add a class library project to your solution.

To my knowledge, there is no counter indication about doing so manualy. I think this is a common usage.

About log4Net config, you don't have to put the config into app.config, you can have a dedicated conf file in your project as well as an app.config file at the same time.

this link http://logging.apache.org/log4net/release/manual/configuration.html will give you examples about both ways (section in app.config and standalone log4net conf file)

Canvas does not using .png file as background image. changing to other file extensions like gif or jpg works fine.

I suggest using a combination of StringReader and my LineReader class, which is part of MiscUtil but also available in this StackOverflow answer - you can easily copy just that class into your own utility project. You'd use it like this:

string text = @"First line
second line
third line";

foreach (string line in new LineReader(() => new StringReader(text)))
{
    Console.WriteLine(line);
}

Looping over all the lines in a body of string data (whether that's a file or whatever) is so common that it shouldn't require the calling code to be testing for null etc :) Having said that, if you do want to do a manual loop, this is the form that I typically prefer over Fredrik's:

using (StringReader reader = new StringReader(input))
{
    string line;
    while ((line = reader.ReadLine()) != null)
    {
        // Do something with the line
    }
}

This way you only have to test for nullity once, and you don't have to think about a do/while loop either (which for some reason always takes me more effort to read than a straight while loop).

You'll need to use a different SimpleDateFormat object for each different pattern. That said, you don't need that many different ones, thanks to this:

Number: For formatting, the number of pattern letters is the minimum number of digits, and shorter numbers are zero-padded to this amount. For parsing, the number of pattern letters is ignored unless it's needed to separate two adjacent fields.

So, you'll need these formats:

• "M/y" (that covers 9/09, 9/2009, and 09/2009)
• "M/d/y" (that covers 9/1/2009)
• "M-d-y" (that covers 9-1-2009)

So, my advice would be to write a method that works something like this (untested):

// ...
List<String> formatStrings = Arrays.asList("M/y", "M/d/y", "M-d-y");
// ...

Date tryParse(String dateString)
{
    for (String formatString : formatStrings)
    {
        try
        {
            return new SimpleDateFormat(formatString).parse(dateString);
        }
        catch (ParseException e) {}
    }

    return null;
}

When attempting to export data using the accepted answer I got an error:

ERROR 1235 (42000) at line 3367: This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table'

As mentioned above:

mysqldump --no-create-info

Will export the data but it will also export the create trigger statements. If like me your outputting database structure (which also includes triggers) with one command and then using the above command to get the data you should also use '--skip-triggers'.

So if you want JUST the data:

mysqldump --no-create-info --skip-triggers

First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).

If your data is not large, you can do

SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'

using OR if you have multiple keywords.

Put the UNIQUE declaration within the column definition section; working example:

CREATE TABLE a (
    i INT,
    j INT,
    UNIQUE(i, j) ON CONFLICT REPLACE
);

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

pool.setValidateConnectionOnBorrow(true);

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

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

See the Oracle documentation for further details.

import base64
from PIL import Image
from io import BytesIO

with open("image.jpg", "rb") as image_file:
    data = base64.b64encode(image_file.read())

im = Image.open(BytesIO(base64.b64decode(data)))
im.save('image1.png', 'PNG')

Agreed with the answer from sll, but experienced another hurdle which was having specified a namespace in the attributes, when receiving the return xml that namespace wasn't included and thus failed finding the class.

i had to find a workaround to specifying the namespace in the attribute and it worked.

ie.

[Serializable()]
    [XmlRoot("Patient", Namespace = "http://www.xxxx.org/TargetNamespace")]
    public class Patient

generated

<Patient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.xxxx.org/TargetNamespace">

but I had to change it to

[Serializable()]
[XmlRoot("Patient")]
public class Patient

which generated to

<Patient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

This solved my problem, hope it helps someone else.

I have found one another simple way to store the data into the database

models.py

class LinkModel(models.Model):
    link = models.CharField(max_length=500)
    shortLink = models.CharField(max_length=30,unique=True)

In database I have only 2 variables

views.py

class HomeView(TemplateView):
    def post(self,request, *args, **kwargs):
        form = LinkForm(request.POST)

        if form.is_valid():
            text = form.cleaned_data['link'] # text for link

        dbobj = LinkModel()
        dbobj.link = text
        self.no = self.gen.generateShortLink() # no for shortLink
        dbobj.shortLink = str(self.no)
        dbobj.save()         # Saving from views.py

In this I have created the instance of model in views.py only and putting/saving data into 2 variables from views only.

Before get permission you can check api version,

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
  {
      if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {

      } 
      else
      {
         ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 401);
      }
  }
  else
  {
    // if version is below m then write code here,          
  }

Get the Result of the permission dialog,

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == 401) {
        if (grantResults.length == 0 || grantResults == null) {

        } else if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            openGallery();
        } else if (grantResults[0] == PackageManager.PERMISSION_DENIED) {
        }
    } else if (requestCode == 402) {
        if (grantResults.length == 0 || grantResults == null) {

        } else if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

        } else if (grantResults[0] == PackageManager.PERMISSION_DENIED) {
        }
    }
} 

There is no way to do this in single query. You have to search the document in first query:

If document exists:

db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Else

db.bar.update( {user_id : 123456 } , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

No need to add condition {$ne : "my_item_two" }.

Also in multithreaded enviourment you have to be careful that only one thread can execute the second (insert case, if document did not found) at a time, otherwise duplicate embed documents will be inserted.

var jsonIssues = [
 {ID:'1',Name:'Some name',Notes:'NOTES'},
 {ID:'2',Name:'Some name 2',Notes:'NOTES 2'}
];

If you want to add to the array then you can do this

jsonIssues[jsonIssues.length] = {ID:'3',Name:'Some name 3',Notes:'NOTES 3'};

Or you can use the push technique that the other guy posted, which is also good.

Thanks to unutbu for the explanation. By default numpy.cov calculates the sample covariance. To obtain the population covariance you can specify normalisation by the total N samples like this:

Covariance = numpy.cov(a, b, bias=True)[0][1]
print(Covariance)

or like this:

Covariance = numpy.cov(a, b, ddof=0)[0][1]
print(Covariance)

In my opinion using a BroadcastReceiver is a cleaner way to cancel a Notification:

In AndroidManifest.xml:

<receiver 
    android:name=.NotificationCancelReceiver" >
    <intent-filter android:priority="999" >
         <action android:name="com.example.cancel" />
    </intent-filter>
</receiver>

In java File:

Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);

NotificationCompat.Action actions[] = new NotificationCompat.Action[1];

NotificationCancelReceiver

public class NotificationCancelReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //Cancel your ongoing Notification
    };
}

       //get the main handle and remove it
       //whatever remains is the child pop up window handle

       String mainHandle = driver.getWindowHandle();
       Set<String> allHandles = driver.getWindowHandles();
       Iterator<String> iter = allHandles.iterator();
       allHandles.remove(mainHandle);
       String childHandle=iter.next();

Denis's answer made me think to another solution using JsonObjects,

a header property checker:

Predicate<object> hasHeader = jsonObject =>
                                 ((JObject)jsonObject).OfType<JProperty>()
                                     .Any(prop => prop.Name == "header");

or maybe better:

Predicate<object> hasHeader = jsonObject =>
                                 ((JObject)jsonObject).Property("header") != null;

for example:

dynamic json = JsonConvert.DeserializeObject(data);
string header = hasHeader(json) ? json.header : null;

function Map() {
    this.keys = new Array();
    this.data = new Object();

    this.put = function (key, value) {
        if (this.data[key] == null) {
            this.keys.push(key);
        }
        this.data[key] = value;
    };

    this.get = function (key) {
        return this.data[key];
    };

    this.remove = function (key) {
        this.keys.remove(key);
        this.data[key] = null;
    };

    this.each = function (fn) {
        if (typeof fn != 'function') {
            return;
        }
        var len = this.keys.length;
        for (var i = 0; i < len; i++) {
            var k = this.keys[i];
            fn(k, this.data[k], i);
        }
    };

    this.entrys = function () {
        var len = this.keys.length;
        var entrys = new Array(len);
        for (var i = 0; i < len; i++) {
            entrys[i] = {
                key: this.keys[i],
                value: this.data[i]
            };
        }
        return entrys;
    };

    this.isEmpty = function () {
        return this.keys.length == 0;
    };

    this.size = function () {
        return this.keys.length;
    };
}

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override

                        return String.class;
                    case 1:
                        return String.class;
                    case 2:
                        return Integer.class;
                    case 3:
                        return Double.class;

                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}

• Always use -r with read.
• There is no need to use cut, you can stick with pure bash solutions.
  • In this case passing read a 2nd var (_) to catch the additional "fields"
• Prefer [[ ]] over [ ].
• Use arithmetic expressions.
• Do not forget to quote variables! Link includes other pitfalls as well

while read -r country _; do
  if [[ $country = 'US' ]]; then
    ((USCOUNTER++))
    echo "US counter $USCOUNTER"
  fi
done < "$FILE"

You cannot do that with the native confirm() as it is the browser’s method.

You have to create a plugin for a confirm box (or try one created by someone else). And they often look better, too.

Additional Tip: Change your English sentence to something like

Hi please check the below link

https://www.postgresql.org/docs/current/xfunc-sql.html

Answering the OP questions

A) What do I not understand about how the Google Apps Script console works with respect to printing so that I can see if my code is accomplishing what I'd like?

The code on .gs files of a Google Apps Script project run on the server rather than on the web browser. The way to log messages was to use the Class Logger.

B) Is it a problem with the code?

As the error message said, the problem was that console was not defined but nowadays the same code will throw other error:

ReferenceError: "playerArray" is not defined. (line 12, file "Code")

That is because the playerArray is defined as local variable. Moving the line out of the function will solve this.

var playerArray = [];

function addplayerstoArray(numplayers) {
  for (i=0; i<numplayers; i++) {
    playerArray.push(i);
  }
}  

addplayerstoArray(7);

console.log(playerArray[3])

Now that the code executes without throwing errors, instead to look at the browser console we should look at the Stackdriver Logging. From the Google Apps Script editor UI click on View > Stackdriver Logging.

Addendum

On 2017 Google released to all scripts Stackdriver Logging and added the Class Console, so including something like console.log('Hello world!') will not throw an error but the log will be on Google Cloud Platform Stackdriver Logging Service instead of the browser console.

From Google Apps Script Release Notes 2017

June 23, 2017

Stackdriver Logging has been moved out of Early Access. All scripts now have access to Stackdriver logging.

From Logging > Stackdriver logging

The following example shows how to use the console service to log information in Stackdriver.

function measuringExecutionTime() {
  // A simple INFO log message, using sprintf() formatting.
  console.info('Timing the %s function (%d arguments)', 'myFunction', 1);

  // Log a JSON object at a DEBUG level. The log is labeled
  // with the message string in the log viewer, and the JSON content
  // is displayed in the expanded log structure under "structPayload".
  var parameters = {
      isValid: true,
      content: 'some string',
      timestamp: new Date()
  };
  console.log({message: 'Function Input', initialData: parameters});

  var label = 'myFunction() time';  // Labels the timing log entry.
  console.time(label);              // Starts the timer.
  try {
    myFunction(parameters);         // Function to time.
  } catch (e) {
    // Logs an ERROR message.
    console.error('myFunction() yielded an error: ' + e);
  }
  console.timeEnd(label);      // Stops the timer, logs execution duration.
}

You are exceeding the length of int datatype. You can use UNSIGNED attribute to support that value.

SIGNED INT can support till 2147483647 and with UNSIGNED INT allows double than this. After this you still want to save data than use CHAR or VARCHAR with length 10

I can think of different method to achieve the same

IList<SelectableEnumItem> result= array;

or (i had some situation that this one didn't work well)

var result = (List<SelectableEnumItem>) array;

or use linq extension

var result = array.CastTo<List<SelectableEnumItem>>();

or

var result= array.Select(x=> x).ToArray<SelectableEnumItem>();

or more explictly

var result= array.Select(x=> new SelectableEnumItem{FirstName= x.Name, Selected = bool.Parse(x.selected) });

please pay attention in above solution I used dynamic Object

I can think of some more solutions that are combinations of above solutions. but I think it covers almost all available methods out there.

Myself I use the first one

I know it's very late for this one... But here is a (not so simple) oneliner to get what you were looking for:

git show-branch --all 2>/dev/null | grep -E "\[$(git branch | grep -E '^\*' | awk '{ printf $2 }')" | tail -n+2 | sed -E "s/^[^\[]*?\[/[/"

• We are listing commits with branch name and relative positions to actual branch states with git show-branch (sending the warnings to /dev/null).
• Then we only keep those with our branch name inside the bracket with grep -E "\[$BRANCH_NAME".
• Where actual $BRANCH_NAME is obtained with git branch | grep -E '^\*' | awk '{ printf $2 }' (the branch with a star, echoed without that star).
• From our results, we remove the redundant line at the beginning with tail -n+2.
• And then, we fianlly clean up the output by removing everything preceding [$BRANCH_NAME] with sed -E "s/^[^\[]*?\[/[/".

The heap part gets worse, my friends. UTF-16 isn't guaranteed to be limited to 16 bits and can expand to 32

After reading the documentation of VideoCapture. I figured out that you can tell VideoCapture, which frame to process next time we call VideoCapture.read() (or VideoCapture.grab()).

The problem is that when you want to read() a frame which is not ready, the VideoCapture object stuck on that frame and never proceed. So you have to force it to start again from the previous frame.

Here is the code

import cv2

cap = cv2.VideoCapture("./out.mp4")
while not cap.isOpened():
    cap = cv2.VideoCapture("./out.mp4")
    cv2.waitKey(1000)
    print "Wait for the header"

pos_frame = cap.get(cv2.cv.CV_CAP_PROP_POS_FRAMES)
while True:
    flag, frame = cap.read()
    if flag:
        # The frame is ready and already captured
        cv2.imshow('video', frame)
        pos_frame = cap.get(cv2.cv.CV_CAP_PROP_POS_FRAMES)
        print str(pos_frame)+" frames"
    else:
        # The next frame is not ready, so we try to read it again
        cap.set(cv2.cv.CV_CAP_PROP_POS_FRAMES, pos_frame-1)
        print "frame is not ready"
        # It is better to wait for a while for the next frame to be ready
        cv2.waitKey(1000)

    if cv2.waitKey(10) == 27:
        break
    if cap.get(cv2.cv.CV_CAP_PROP_POS_FRAMES) == cap.get(cv2.cv.CV_CAP_PROP_FRAME_COUNT):
        # If the number of captured frames is equal to the total number of frames,
        # we stop
        break

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

McGarnagle has a great answer, and you'll want to be accepting his, but I thought I'd mention (since you asked) how databinding works.

It's generally implemented by firing events whenever a change is made to the data, which then causes listeners (e.g. the UI) to be updated.

Two-way binding works by doing this twice, with a bit of care taken to ensure that you don't wind up stuck in an event loop (where the update from the event causes another event to be fired).

I was gonna put this in a comment, but it was getting pretty long...

A very easy solution worked for me:

  if (62 % 50 != 0) {
      var number = 62 / 50 + 1 // adding 1 is doing the actual "round up"
  }

number contains value 2

In your destination field you want to use VLOOKUP like so:

=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)

VLOOKUP Arguments:

1. The set fields you want to lookup.
2. The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
3. This defines what field you want to display upon a match.
4. FALSE tells VLOOKUP to do an exact match.

This will work like a charm.

Simple Find Write Code in On Location Method

public void onLocationChanged(Location location) {
    if (mCurrLocationMarker != null) {
        mCurrLocationMarker.remove();
    }


    //Place current location marker
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    MarkerOptions markerOptions = new MarkerOptions();
    markerOptions.position(latLng);
    markerOptions.title("Current Position");
    markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));
    mCurrLocationMarker = mMap.addMarker(markerOptions);

    //move map camera
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mMap.animateCamera(CameraUpdateFactory.zoomTo(18));

    PolylineOptions pOptions = new PolylineOptions()
            .width(5)
            .color(Color.GREEN)
            .geodesic(true);
    for (int z = 0; z < routePoints.size(); z++) {
        LatLng point = routePoints.get(z);
        pOptions.add(point);
    }
    line = mMap.addPolyline(pOptions);
    routePoints.add(latLng);
}

You could simply look in the Active Record Rake tasks as that is where I believe they live as in this file. https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/lib/active_record/tasks/database_tasks.rb

What they do is your question right?

That depends on where they come from and this is just and example to show that they vary depending upon the task. Here we have a different file full of tasks.

https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/Rakefile

which has these tasks.

namespace :db do
  task create: ["db:mysql:build", "db:postgresql:build"]
  task drop: ["db:mysql:drop", "db:postgresql:drop"]
end

This may not answer your question but could give you some insight into go ahead and look the source over especially the rake files and tasks. As they do a pretty good job of helping you use rails they don't always document the code that well. We could all help there if we know what it is supposed to do.

@vj9 thx. I update to xcode 7 . It show me the same error. Build well after set "NO"

set "NO" it works well.

To do anything other than declare a pointer to an object, you need the full definition.

The best solution is to move the implementation in a separate file.

If you must keep this in a header, move the definition after both declarations:

class tile_tree_apple;

class tile_tree : public tile
{
  public:
      tile onDestroy();
      tile tick();
      void onCreate();        
};

class tile_tree_apple : public tile
{
  public:
      tile onDestroy();
      tile tick();
      void onCreate(); 
      tile onUse();       
};

tile tile_tree::onDestroy() {return *new tile_grass;};
tile tile_tree::tick() {if (rand()%20==0) return *new tile_tree_apple;};
void tile_tree::onCreate() {health=rand()%5+4; type=TILET_TREE;};        

tile tile_tree_apple::onDestroy() {return *new tile_grass;};
tile tile_tree_apple::tick() {if (rand()%20==0) return *new tile_tree;};
void tile_tree_apple::onCreate() {health=rand()%5+4; type=TILET_TREE_APPLE;}; 
tile tile_tree_apple::onUse() {return *new tile_tree;};       

Important

You have memory leaks:

tile tile_tree::onDestroy() {return *new tile_grass;};

will create an object on the heap, which you can't destroy afterwards, unless you do some ugly hacking. Also, your object will be sliced. Don't do this, return a pointer.
