Programs & Examples On #Enumset

private ComboBox gender;
private enum Selgender{Male,Famle};
ObservableList<Object> observableList  =FXCollections.observableArrayList(Selgender.values());

It looks OK apart from the space in your ID attribute, which is not valid, and the fact that you're replacing the value of your input before checking the selection.

function textbox()_x000D_
{_x000D_
        var ctl = document.getElementById('Javascript_example');_x000D_
        var startPos = ctl.selectionStart;_x000D_
        var endPos = ctl.selectionEnd;_x000D_
        alert(startPos + ", " + endPos);_x000D_
}

<input id="Javascript_example" name="one" type="text" value="Javascript example" onclick="textbox()">

Also, if you're supporting IE <= 8 you need to be aware that those browsers do not support selectionStart and selectionEnd.

You can get the context using getActivity().getApplicationContext();

I've seen many answers regarding the bootstrap events such as hide.bs.modal which triggers when the modal closes.

There's a problem with those events: any popups in the modal (popovers, tooltips, etc) will trigger that event.

There is another way to catch the event when a modal closes.

$(document).on('hidden','#modal:not(.in)', function(){} );

Bootstrap uses the in class when the modal is open. It is very important to use the hidden event since the class in is still defined when the event hideis triggered.

This solution will not work in IE8 since IE8 does not support the Jquery :not() selector.

If the URL is using https instead of http, you need to add the following line:

parsed_url = URI.parse(url)
http = Net::HTTP.new(parsed_url.host, parsed_url.port)
http.use_ssl = true

Note the additional http.use_ssl = true.

And the more appropriate code which would handle both http and https will be similar to the following one.

url = URI.parse(domain)
req = Net::HTTP::Post.new(url.request_uri)
req.set_form_data({'name'=>'Sur Max', 'email'=>'[email protected]'})
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = (url.scheme == "https")
response = http.request(req)

See more in my blog: EOFError: end of file reached issue when post a form with Net::HTTP.

You can take a look at the Rails documentation . Anyways , in your form :

  <%= f.collection_select :provider_id, Provider.order(:name),:id,:name, include_blank: true %>

As you can guess , you should predefine email-providers in another model -Provider , to have where to select them from .

This is working

<form name="myform" ng-submit="create()">
    <input type="number"
           name="price_field"
           ng-model="price"
           require
           ng-pattern="/^\d{0,9}(\.\d{1,9})?$/">
    <span  ng-show="myform.price_field.$error.pattern">Not valid number!</span>
    <input type="submit" class="btn">

Just define a helper in application helper directory then call from your controller just function name like

helper name = new_helper.php
function test_method($data){
 return $data
}   

in controller load the helper

$this->load->new_helper();
$result =  test_method('Hello world!');
if($result){
 echo $result
}

output will be

Hello World!

today I found a problem, the profile images was returning the default profile picture because a new requirement from Facebook to all the UID based queries, so just add &access_token=[apptoken] to the url, you can obtain your app token from here

Make sure the integer value is ASCII value of an alphabet/character.

If not then make it.

for e.g. if int i=1

then add 64 to it so that it becomes 65 = ASCII value of 'A' Then use

char x = (char)i;

print x

// 'A' will be printed 

Maybe it can be useful for someone:

// Printing the SQL with real values
$vals = $query->getFlattenedParams();
foreach(explode('?', $query->getSqlQuery()) as $i => $part) {
    $sql = (isset($sql) ? $sql : null) . $part;
    if (isset($vals[$i])) $sql .= $vals[$i];
}

echo $sql;

There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:

split(string str, string pat)
   Split str around pat (pat is a regular expression) 

In your case, the delimiter "|" has a special meaning as a regular expression, so it should be referred to as "\\|".

The top answer is the best! However, it was not triggering mouse events for me in Firefox when etype = 'click'.

So, I changed the document.createEvent to 'MouseEvents' and that fixed the problem. The extra code is to test whether or not another bit of code was interfering with the event, and if it was cancelled I would log that to console.

function eventFire(el, etype){
  if (el.fireEvent) {
    el.fireEvent('on' + etype);
  } else {
    var evObj = document.createEvent('MouseEvents');
    evObj.initEvent(etype, true, false);
    var canceled = !el.dispatchEvent(evObj);
    if (canceled) {
      // A handler called preventDefault.
      console.log("automatic click canceled");
    } else {
      // None of the handlers called preventDefault.
    } 
  }
}

what about this simple inArray function:

Function isInArray(ByRef stringToBeFound As String, ByRef arr As Variant) As Boolean
For Each element In arr
    If element = stringToBeFound Then
        isInArray = True
        Exit Function
    End If
Next element
End Function

I know this is a very old question but feel this adds a valuable alternative of how to deal with the console issue. Place the following code before any call to console.* (so your very first script).

// Avoid `console` errors in browsers that lack a console.
(function() {
    var method;
    var noop = function () {};
    var methods = [
        'assert', 'clear', 'count', 'debug', 'dir', 'dirxml', 'error',
        'exception', 'group', 'groupCollapsed', 'groupEnd', 'info', 'log',
        'markTimeline', 'profile', 'profileEnd', 'table', 'time', 'timeEnd',
        'timeStamp', 'trace', 'warn'
    ];
    var length = methods.length;
    var console = (window.console = window.console || {});

    while (length--) {
        method = methods[length];

        // Only stub undefined methods.
        if (!console[method]) {
            console[method] = noop;
        }
    }
}());

Use a function like this:

    public static string FlattenException(Exception exception)
    {
        var stringBuilder = new StringBuilder();

        while (exception != null)
        {
            stringBuilder.AppendLine(exception.Message);
            stringBuilder.AppendLine(exception.StackTrace);

            exception = exception.InnerException;
        }

        return stringBuilder.ToString();
    }

Then you can call it like this:

try
{
    // invoke code above
}
catch(MyCustomException we)
{
    Debug.Writeline(FlattenException(we));
}

To do this without relying on any GNUisms such as -i without a parameter or c without a linebreak:

sed '/TEXT_TO_BE_REPLACED/c\
This line is removed by the admin.
' infile > tmpfile && mv tmpfile infile

In this (POSIX compliant) form of the command

c\
text

text can consist of one or multiple lines, and linebreaks that should become part of the replacement have to be escaped:

c\
line1\
line2
s/x/y/

where s/x/y/ is a new sed command after the pattern space has been replaced by the two lines

line1
line2

You can add 'debugger' in your code and reload the app, which puts the breakpoint there and you can 'step over' , or run.

var service = {
user_id: null,
getCurrentUser: function() {
  debugger; // Set the debugger inside 
            // this function
  return service.user_id;
}

The concept of POD and the type trait std::is_pod will be deprecated in C++20. See this question for further information.

foreach (DataRow dr in ds.Tables[0].Rows)
{
    //your code here
}

Modules go in site-packages and executables go in your system's executable path. For your environment, this path is /usr/local/bin/.

To avoid having to deal with this, simply use easy_install, distribute or pip. These tools know which files need to go where.

When doing a clean HTML Structure, you can use this.

//Jquery Code_x000D_
$('a#link_1').click(function(e){_x000D_
  e . preventDefault () ;_x000D_
  var a = e . target ;_x000D_
  window . open ( '_top' , a . getAttribute ('href') ) ;_x000D_
});_x000D_
_x000D_
//Normal Code_x000D_
element = document . getElementById ( 'link_1' ) ;_x000D_
element . onClick = function (e) {_x000D_
  e . preventDefault () ;_x000D_
  _x000D_
  window . open ( '_top' , element . getAttribute ('href') ) ;_x000D_
} ;

<a href="#Foo" id="link_1">Do it!</a>

If your string is all caps then below method will work

labelTitle.text = remarks?.lowercased().firstUppercased

This extension will helps you

extension StringProtocol {
    var firstUppercased: String {
        guard let first = first else { return "" }
        return String(first).uppercased() + dropFirst()
    }
}

import regex
text = 'ask her to call Mary back when she comes back'                           
p = r'(?i)(?s)call(.*?)back'
for match in regex.finditer(p, str(text)):
    print (match.group(1))

Output: Mary

After valueTuples, what's the use of ExpandoObject class? this 6 lines code with ExpandoObject:

dynamic T = new ExpandoObject();
T.x = 1;
T.y = 2;
T.z = new ExpandoObject();
T.z.a = 3;
T.b= 4;

can be written in one line with tuples:

var T = (x: 1, y: 2, z: (a: 3, b: 4));

besides with tuple syntax you have strong type inference and intlisense support

I had a similar issue. I needed to keep the legacy encrypted passwords (Base64/SHA-1/Random salt Encoded) as users will not want to change their passwords or re-register. However I wanted to use the BCrypt encoder moving forward too.

My solution was to write a bespoke decoder that checks to see which encryption method was used first before matching (BCrypted ones start with $).

To get around the salt issue, I pass into the decoder a concatenated String of salt + encrypted password via my modified user object.

Decoder

@Component
public class LegacyEncoder implements PasswordEncoder {

    private static final String BCRYP_TYPE = "$";
    private static final PasswordEncoder BCRYPT = new BCryptPasswordEncoder();

    @Override
    public String encode(CharSequence rawPassword) {

    return BCRYPT.encode(rawPassword);
    }

    @Override
    public boolean matches(CharSequence rawPassword, String encodedPassword) {

    if (encodedPassword.startsWith(BCRYP_TYPE)) {
        return BCRYPT.matches(rawPassword, encodedPassword);
    }

    return sha1SaltMatch(rawPassword, encodedPassword);
    }

    @SneakyThrows
    private boolean sha1SaltMatch(CharSequence rawPassword, String encodedPassword) {

    String[] saltHash = encodedPassword.split(User.SPLIT_CHAR);

    // Legacy code from old system   
    byte[] b64salt = Base64.getDecoder().decode(saltHash[0].getBytes());
    byte[] validHash = Base64.getDecoder().decode(saltHash[1]);
    byte[] checkHash = Utility.getHash(5, rawPassword.toString(), b64salt);

    return Arrays.equals(checkHash, validHash);
    }

}

User Object

public class User implements UserDetails {

    public static final String SPLIT_CHAR = ":";

    @Id
    @Column(name = "user_id", nullable = false)
    private Integer userId;

    @Column(nullable = false, length = 60)
    private String password;

    @Column(nullable = true, length = 32)
    private String salt;

.
.

    @PostLoad
    private void init() {

    username = emailAddress; //To comply with UserDetails
    password = salt == null ? password : salt + SPLIT_CHAR + password;
    }        

You can also add a hook to re-encode the password in the new BCrypt format and replace it. Thus phasing out the old method.

for me it was a path issue when saving the image.

int count = Directory.EnumerateFiles(System.Web.HttpContext.Current.Server.MapPath("~/images/savedimages"), "*").Count();

var img = Base64ToImage(imgRaw);

string path = "images/savedimages/upImages" + (count + 1) + ".png";

img.Save(Path.Combine(System.Web.HttpContext.Current.Server.MapPath(path)));

return path;

So I fixed it by adding the following forward slash

String path = "images/savedimages....

should be

String path = "/images/savedimages....

Hope that helps anyone stuck!

Better late than never:) The previous answer with paginator is really good. However it is recursive, and you might end up hitting Python's recursion limits. Here's an alternate approach, with a couple of extra checks.

import os
import errno
import boto3


def assert_dir_exists(path):
    """
    Checks if directory tree in path exists. If not it created them.
    :param path: the path to check if it exists
    """
    try:
        os.makedirs(path)
    except OSError as e:
        if e.errno != errno.EEXIST:
            raise


def download_dir(client, bucket, path, target):
    """
    Downloads recursively the given S3 path to the target directory.
    :param client: S3 client to use.
    :param bucket: the name of the bucket to download from
    :param path: The S3 directory to download.
    :param target: the local directory to download the files to.
    """

    # Handle missing / at end of prefix
    if not path.endswith('/'):
        path += '/'

    paginator = client.get_paginator('list_objects_v2')
    for result in paginator.paginate(Bucket=bucket, Prefix=path):
        # Download each file individually
        for key in result['Contents']:
            # Calculate relative path
            rel_path = key['Key'][len(path):]
            # Skip paths ending in /
            if not key['Key'].endswith('/'):
                local_file_path = os.path.join(target, rel_path)
                # Make sure directories exist
                local_file_dir = os.path.dirname(local_file_path)
                assert_dir_exists(local_file_dir)
                client.download_file(bucket, key['Key'], local_file_path)


client = boto3.client('s3')

download_dir(client, 'bucket-name', 'path/to/data', 'downloads')

As documented in ?legend you do this like so:

plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)

Line breaks are achieved with the new line character \n. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.

Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).

ssh-keygen isn't a windows executable.
You can use PuttyGen (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) for example to create a key

Pulling data type from information_schema is possible, but not convenient (requires joining several columns with a case statement). Alternatively one can use format_type built-in function to do that, but it works on internal type identifiers that are visible in pg_attribute but not in information_schema. Example

SELECT a.attname as column_name, format_type(a.atttypid, a.atttypmod) AS data_type
FROM pg_attribute a JOIN pg_class b ON a.attrelid = b.relfilenode
WHERE a.attnum > 0 -- hide internal columns
AND NOT a.attisdropped -- hide deleted columns
AND b.oid = 'my_table'::regclass::oid; -- example way to find pg_class entry for a table

In Maven project, You can build jar automatically using Maven War plugin by setting archiveClasses to true. Example below.

<plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-war-plugin</artifactId>
       <configuration>
        <archiveClasses>true</archiveClasses>
       </configuration>
</plugin>

So apparently there is nothing similar for vector-wise comparison. An obvious Python way to do so would be:

names = ['bob', 'john', 'mike']
any(st in 'bob and john' for st in names) 
>> True

any(st in 'mary and jane' for st in names) 
>> False

Ian Kemp has the answer (have some points btw..), this is to simply add some meat to one of his steps.

The reason I ended up here was that dev's machines were building fine, but the build server simply wasn't pulling down the packages required (empty packages folder) and therefore the build was failing. Logging onto the build server and manually building the solution worked, however.

To fulfil the second of Ians 3 point steps (running nuget restore), you can create an MSBuild target running the exec command to run the nuget restore command, as below (in this case nuget.exe is in the .nuget folder, rather than on the path), which can then be run in a TeamCity build step (other CI available...) immediately prior to building the solution

<Target Name="BeforeBuild">
  <Exec Command="..\.nuget\nuget restore ..\MySolution.sln"/>
</Target>

For the record I'd already tried the "nuget installer" runner type but this step was hanging on web projects (worked for DLL's and Windows projects)

one = [1, 2, 3]
two = [9, 8, 5, 3, 2, 1]

all(x in two for x in one)

Explanation: Generator creating booleans by looping through list one checking if that item is in list two. all() returns True if every item is truthy, else False.

There is also an advantage that all return False on the first instance of a missing element rather than having to process every item.

Well; this works as well:

home = "$System.env.HOME"

It's not clear what you're aiming for.

It does work by just taking the argument 'rb' read binary instead of 'r' read

I had this issue when accessing actuator. Putting following configuration class solved the issue:

@Configuration
@EnableWebMvc
public class MediaConverterConfiguration implements WebMvcConfigurer {
    @Bean
    public MappingJackson2HttpMessageConverter jacksonConverter() {
        MappingJackson2HttpMessageConverter mc =
                new MappingJackson2HttpMessageConverter();
        List<MediaType> supportedMediaTypes =
                new ArrayList<>(mc.getSupportedMediaTypes());
        supportedMediaTypes
                .add(MediaType.valueOf(MediaType.APPLICATION_JSON_VALUE));
        supportedMediaTypes.add(
            MediaType.valueOf("application/vnd.spring-boot.actuator.v2+json"));
        mc.setSupportedMediaTypes(supportedMediaTypes);
        return mc;
    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(jacksonConverter());

The official link no longer offers the original source code. The official link and casual google searches will land you with open jdk. Open jdk causes problems with android build unless the build script files are modified. The original package can be found here:

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

Replace the comma with a dot.

This will only return 554:

var value = parseFloat("554,20")

This will return 554.20:

var value = parseFloat("554.20")

So in the end, you can simply use:

var fValue = parseFloat(document.getElementById("textfield").value.replace(",","."))

Don't forget that parseInt() should only be used to parse integers (no floating points). In your case it will only return 554. Additionally, calling parseInt() on a float will not round the number: it will take its floor (closest lower integer).

Extended example to answer Pedro Ferreira's question from the comments:

If the textfield contains thousands separator dots like in 1.234.567,99 those could be eliminated beforehand with another replace:

var fValue = parseFloat(document.getElementById("textfield").value.replace(/\./g,"").replace(",","."))

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

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

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

Bundles can be used to send arbitrary data from one activity to another by way of Intents. When you broadcast an Intent, interested Activities (and other BroadcastRecievers) will be notified of this. An intent can contain a Bundle so that you can send extra data along with the Intent.

Bundles are key-value mappings, so in a way they are like a Hash, but they are not strictly limited to a single String / Foo object mapping. Note that only certain data types are considered "Parcelable" and they are explicitly spelled out in the Bundle API.

if you want the label to take dynamic lines you may use this

label.numberOfLines = 0; // allows label to have as many lines as needed
label.text = @"some long text ";
[label sizeToFit];
NSLog(@"Label's frame is: %@", NSStringFromCGRect(label.frame));

If you don't have permission to link servers, here are the steps to import a table from one server to another using Sql Server Import/Export Wizard:

• Right click on the source database you want to copy from.
• Select Tasks - Export Data.
• Select Sql Server Native Client in the data source.
• Select your authentication type (Sql Server or Windows authentication).
• Select the source database.
• Next, choose the Destination: Sql Server Native Client
• Type in your Server Name (the server you want to copy the table to).
• Select your authentication type (Sql Server or Windows authentication).
• Select the destination database.
• Select Copy data.
• Select your table from the list.
• Hit Next, Select Run immediately, or optionally, you can also save the package to a file or Sql Server if you want to run it later.
• Finish

SELECT * FROM table
ORDER BY NEWID()

[Linqer] is a SQL to LINQ converter tool. It helps you to learn LINQ and convert your existing SQL statements.

Not every SQL statement can be converted to LINQ, but Linqer covers many different types of SQL expressions. Linqer supports both .NET languages - C# and Visual Basic.

The new build system in Android Studio creates a build folder. The code inspection barfs on this folder as well as the gradle folder. These folders should proably be ignored when running code inspection.

I have raised an issue with the Android Studio team at:

https://code.google.com/p/android/issues/detail?id=56415

For the same issue, I used an easy solution : put a padding-top of 40px on each anchor.

when use @Value, you should add @PropertySource annotation on Class, or specify properties holder in spring's xml file. eg.

@Component
@PropertySource("classpath:config.properties")
public class BusinessClass{
   @Value("${user.name}")
   private String name;
   @Value("${user.age}")
   private int age;
   @Value("${user.registed:false}")
   private boolean registed;
}

config.properties

user.name=test
user.age=20
user.registed=true

this works!

Of course, you can use placeholder xml configuration instead of annotation. spring.xml

<context:property-placeholder location="classpath:config.properties"/>

    Matcher matcherDot = patternWithDot.matcher(s);
    Matcher matcherComa = patternWithComma.matcher(s);

    return matcherDot.matches() || matcherComa.matches();

Usage:

myTextEdit.addTextChangedListener(new DecimalInputTextWatcher(myTextEdit, 2));

Both Google and Python's style guide is the best practice:

if x is not None:
    # Do something about x

Using not x can cause unwanted results.

See below:

>>> x = 1
>>> not x
False
>>> x = [1]
>>> not x
False
>>> x = 0
>>> not x
True
>>> x = [0]         # You don't want to fall in this one.
>>> not x
False

You may be interested to see what literals are evaluated to True or False in Python:

• Truth Value Testing

Edit for comment below:

I just did some more testing. not x is None doesn't negate x first and then compared to None. In fact, it seems the is operator has a higher precedence when used that way:

>>> x
[0]
>>> not x is None
True
>>> not (x is None)
True
>>> (not x) is None
False

Therefore, not x is None is just, in my honest opinion, best avoided.

More edit:

I just did more testing and can confirm that bukzor's comment is correct. (At least, I wasn't able to prove it otherwise.)

This means if x is not None has the exact result as if not x is None. I stand corrected. Thanks bukzor.

However, my answer still stands: Use the conventional if x is not None. :]

This bug still exists in 0.8+/1.10

With Jackson

compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-csv:2.2.2'

I had to include as well as the above suggestion before it would compile

exclude 'META-INF/services/com.fasterxml.jackson.core.JsonFactory'

If i say without loop, i can use GOTO statement for delete large amount of records using sql server. exa.

 IsRepeat:
    DELETE TOP (10000)
    FROM <TableName>
    IF @@ROWCOUNT > 0
         GOTO IsRepeat

like this way you can delete large amount of data with smaller size of delete.

let me know if requires more information.

You don't need arrays for this. Try something like:

ActiveSheet.Range("$A$1:$A$" & LastRow).RemoveDuplicates Columns:=1, Header:=xlYes

If there's no header, change accordingly.

EDIT: Here's the traditional method, which takes advantage of the fact that each item in a Collection must have a unique key:

Sub test()
Dim ws As Excel.Worksheet
Dim LastRow As Long
Dim coll As Collection
Dim cell As Excel.Range
Dim arr() As String
Dim i As Long

Set ws = ActiveSheet
With ws
    LastRow = .Range("C" & .Rows.Count).End(xlUp).Row
    Set coll = New Collection
    For Each cell In .Range("C4:C" & LastRow)
        On Error Resume Next
        coll.Add cell.Value, CStr(cell.Value)
        On Error GoTo 0
    Next cell
    ReDim arr(1 To coll.Count)
    For i = LBound(arr) To UBound(arr)
        arr(i) = coll(i)
        'to show in Immediate Window
        Debug.Print arr(i)
    Next i
End With
End Sub

Determining the index from the boolean as described above e.g.

df[df['column'].isin(values)].index

can be more memory intensive than determining the index using this method

pd.Index(np.where(df['column'].isin(values))[0])

applied like so

df.drop(pd.Index(np.where(df['column'].isin(values))[0]), inplace = True)

This method is useful when dealing with large dataframes and limited memory.

The .NET garbage collector takes care of all this for you.

It is able to determine when objects are no longer referenced and will (eventually) free the memory that had been allocated to them.

What I ended up doing is something like this:

In the controller:

link: function($scope, $element, $attr) {
  $scope.scope = $scope;  // or $scope.$parent, as needed
  $scope.field = $attr.field = '_suffix';
  $scope.subfield = $attr.sub_node;
  ...

so in the templates I could use totally dynamic names, and not just under a certain hard-coded element (like in your "Answers" case):

<textarea ng-model="scope[field][subfield]"></textarea>

Hope this helps.

? Splitting line in Python:

Have you tried using str.splitlines() method?:

• Python 2.X documentation here.
• Python 3.X documentation here.

From the docs:

str.splitlines([keepends])

Return a list of the lines in the string, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true.

For example:

>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()
['Line 1', '', 'Line 3', 'Line 4']

>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines(True)
['Line 1\n', '\n', 'Line 3\r', 'Line 4\r\n']

Which delimiters are considered?

This method uses the universal newlines approach to splitting lines.

The main difference between Python 2.X and Python 3.X is that the former uses the universal newlines approach to splitting lines, so "\r", "\n", and "\r\n" are considered line boundaries for 8-bit strings, while the latter uses a superset of it that also includes:

• \v or \x0b: Line Tabulation (added in Python 3.2).
• \f or \x0c: Form Feed (added in Python 3.2).
• \x1c: File Separator.
• \x1d: Group Separator.
• \x1e: Record Separator.
• \x85: Next Line (C1 Control Code).
• \u2028: Line Separator.
• \u2029: Paragraph Separator.

splitlines VS split:

Unlike str.split() when a delimiter string sep is given, this method returns an empty list for the empty string, and a terminal line break does not result in an extra line:

>>> ''.splitlines()
[]

>>> 'Line 1\n'.splitlines()
['Line 1']

While str.split('\n') returns:

>>> ''.split('\n')
['']

>>> 'Line 1\n'.split('\n')
['Line 1', '']

?? Removing additional whitespace:

If you also need to remove additional leading or trailing whitespace, like spaces, that are ignored by str.splitlines(), you could use str.splitlines() together with str.strip():

>>> [str.strip() for str in 'Line 1  \n  \nLine 3 \rLine 4 \r\n'.splitlines()]
['Line 1', '', 'Line 3', 'Line 4']

? Removing empty strings (''):

Lastly, if you want to filter out the empty strings from the resulting list, you could use filter():

>>> # Python 2.X:
>>> filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines())
['Line 1', 'Line 3', 'Line 4']

>>> # Python 3.X:
>>> list(filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()))
['Line 1', 'Line 3', 'Line 4']

Additional comment regarding the original question:

As the error you posted indicates and Burhan suggested, the problem is from the print. There's a related question about that could be useful to you: UnicodeEncodeError: 'charmap' codec can't encode - character maps to <undefined>, print function

In order to populate referenced subdocuments, you need to explicitly define the document collection to which the ID references to (like created_by: { type: Schema.Types.ObjectId, ref: 'User' }).

Given this reference is defined and your schema is otherwise well defined as well, you can now just call populate as usual (e.g. populate('comments.created_by'))

Proof of concept code:

// Schema
var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var UserSchema = new Schema({
  name: String
});

var CommentSchema = new Schema({
  text: String,
  created_by: { type: Schema.Types.ObjectId, ref: 'User' }
});

var ItemSchema = new Schema({
   comments: [CommentSchema]
});

// Connect to DB and instantiate models    
var db = mongoose.connect('enter your database here');
var User = db.model('User', UserSchema);
var Comment = db.model('Comment', CommentSchema);
var Item = db.model('Item', ItemSchema);

// Find and populate
Item.find({}).populate('comments.created_by').exec(function(err, items) {
    console.log(items[0].comments[0].created_by.name);
});

Finally note that populate works only for queries so you need to first pass your item into a query and then call it:

item.save(function(err, item) {
    Item.findOne(item).populate('comments.created_by').exec(function (err, item) {
        res.json({
            status: 'success',
            message: "You have commented on this item",
            comment: item.comments.id(comment._id)
        });
    });
});

In order to create an array of objects, the objects need a constructor that doesn't take any paramters (that creates a default form of the object, eg. with both strings empty). This is what the error message means. The compiler automatically generates a constructor which creates an empty object unless there are any other constructors.

If it makes sense for the array elements to be created empty (in which case the members acquire their default values, in this case, empty strings), you should:

-Write an empty constructor:

class name {
  public:
    string first;
    string last;

  name() { }
  name(string a, string b){
    first = a;
    last = b;
  }
};

-Or, if you don't need it, remove the existing constructor.

If an "empty" version of your class makes no sense, there is no good solution to provide initialisation paramters to all the elements of the array at compile time. You can:

• Have a constructor create an empty version of the class anyway, and an init() function which does the real initialisation
• Use a vector, and on initialisation create the objects and insert them into the vector, either using vector::insert or a loop, and trust that not doing it at compile time doesn't matter.
• If the object can't be copied either, you can use an array/vector of smart pointers to the object and allocate them on initialisation.
• If you can use C++11 I think (?) you can use initialiser lists to initialise a vector and intialise it (I'm not sure if that works with any contructor or only if the object is created from a single value of another type). Eg: .

 std::vector<std::string> v = { "xyzzy", "plugh", "abracadabra" };

`

According to the below scenario ,

Let's say that someone makes a request to your server with data that is in the correct format, but is simply not "good" data. So for example, imagine that someone posted a String value to an API endpoint that expected a String value; but, the value of the string contained data that was blacklisted (ex. preventing people from using "password" as their password). then the status code could be either 400 or 422 ?

Until now, I would have returned a "400 Bad Request", which, according to the w3.org, means:

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

This description doesn't quite fit the circumstance; but, if you go by the list of core HTTP status codes defined in the HTTP/1.1 protocol, it's probably your best bet.

Recently, however, Someone from my Dev team pointed out [to me] that popular APIs are starting to use HTTP extensions to get more granular with their error reporting. Specifically, many APIs, like Twitter and Recurly, are using the status code "422 Unprocessable Entity" as defined in the HTTP extension for WebDAV. HTTP status code 422 states:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

Going back to our password example from above, this 422 status code feels much more appropriate. The server understands what you're trying to do; and it understands the data that you're submitting; it simply won't let that data be processed.

If you are looking for empty string in addition to whitespace you meed to use * rather than +

var regex = /^\s*$/ ;
                ^

getline, as it name states, read a whole line, or at least till a delimiter that can be specified.

So the answer is "no", getlinedoes not match your need.

But you can do something like:

inFile >> first_name >> last_name >> age;
name = first_name + " " + last_name;

The real question is why does it generate a 500 error. If it is related to any input parameters, then I would argue that it should be handled internally and returned as a 400 series error. Generally a 400, 404 or 406 would be appropriate to reflect bad input since the general convention is that a RESTful resource is uniquely identified by the URL and a URL that cannot generate a valid response is a bad request (400) or similar.

If the error is caused by anything other than the inputs explicitly or implicitly supplied by the request, then I would say a 500 error is likely appropriate. So a failed database connection or other unpredictable error is accurately represented by a 500 series error.

Public Function TestError() As String()
     Return {"foo", "bar"}
End Function

Works fine for me and should work for you, but you may need allow using implicit declarations in your project. I believe this is turning off Options strict in the Compile section of the program settings.

Since you are using VS 2008 (VB.NET 9.0) you have to declare create the new instance

New String() {"foo", "Bar"}

If you did a custom installation you need to add Microsoft Sql Server Data Tools. After that you can add Reportviwer to your webform.

I follow this simple way:

• Double click (Highlight) single tab (ie: \t).
• Press ctrl + F (Find/repace).
• You may not see \t or single tab area on Find What: field. But don't worry.
• Enter a space in Replace With: field.
• Click Replce All .

Done! :)

See:

Note: This method applies to reverse (Replace a space by a tab) case too.

I saw next comment about this

It's also helpful to place the badge inline if you want to apply your own CSS to it. But do remember that you agreed to show Google's Terms and conditions when you registered for an API key - so don't hide it, please. And while it is possible to make the badge disappear completely with CSS, we wouldn't recommend it.

Use function itoa() to convert an integer to a string

For example:

char msg[30];
int num = 10;
itoa(num,msg,10);

You can use the flip commands numpy.flipud() or numpy.fliplr() to get the indexes in descending order after sorting using the argsort command. Thats what I usually do.

I wrote a function in PHP to let me to this, I hope its useful to someone. The path to the thumbnail is contained within a link tag on the video page. This seems to do the trick for me.

    $video_url = "http://vimeo.com/7811853"  
    $file = fopen($video_url, "r");
    $filedata = stream_get_contents($file);
    $html_content = strpos($filedata,"<link rel=\"videothumbnail");
    $link_string = substr($filedata, $html_content, 128);
    $video_id_array = explode("\"", $link_string);
    $thumbnail_url = $video_id_array[3];
    echo $thumbnail_url;

Hope it helps anyone.

Foggson

both your conditions are the same:

if(s < f) {     calc = f - s;     n = s; }else if(f > s){     calc =  s - f;     n = f;  } 

so

if(s < f)   

and

}else if(f > s){ 

are the same

change to

}else if(f < s){ 

You can use the below query to remove all the rows from the table, also you should keep it in mind that it will reset the Identity too.

TRUNCATE TABLE table_name

The following is a regular expression matching a multiline block of text:

import re
result = re.findall('(startText)(.+)((?:\n.+)+)(endText)',input)

There are many reasons to discourage including a .cpp file, but it isn't strictly disallowed. Your example should compile fine.

The problem is probably that you're compiling both main.cpp and foop.cpp, which means two copies of foop.cpp are being linked together. The linker is complaining about the duplication.

In *nix systems, use the WHICH command to show the location of the mysqldump, try this :

<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'password';
$dbname = 'test';
$mysqldump=exec('which mysqldump');


$command = "$mysqldump --opt -h $dbhost -u $dbuser -p $dbpass $dbname > $dbname.sql";

exec($command);
?>

In my case I had previously initialized a git directory where I was trying to create a new one. I just deleted all the old files and started from scratch.

Java provides two interesting Boolean operators not found in most other computer languages. These secondary versions of AND and OR are known as short-circuit logical operators. As you can see from the preceding table, the OR operator results in true when A is true, no matter what B is.

Similarly, the AND operator results in false when A is false, no matter what B is. If you use the || and && forms, rather than the | and & forms of these operators, Java will not bother to evaluate the right-hand operand alone. This is very useful when the right-hand operand depends on the left one being true or false in order to function properly.

For example, the following code fragment shows how you can take advantage of short-circuit logical evaluation to be sure that a division operation will be valid before evaluating it:

if ( denom != 0 && num / denom >10)

Since the short-circuit form of AND (&&) is used, there is no risk of causing a run-time exception from dividing by zero. If this line of code were written using the single & version of AND, both sides would have to be evaluated, causing a run-time exception when denom is zero.

It is standard practice to use the short-circuit forms of AND and OR in cases involving Boolean logic, leaving the single-character versions exclusively for bitwise operations. However, there are exceptions to this rule. For example, consider the following statement:

 if ( c==1 & e++ < 100 ) d = 100;

Here, using a single & ensures that the increment operation will be applied to e whether c is equal to 1 or not.

Well, if you had already created the log4j.properties you would add its path to the classpath so it would be found during execution.
Yes, the thingy will search for this file in the classpath.
Since you said you looked into axis and didnt find one, I am assuming you dont have a log4j.properties, so here's a crude but complete example.
Create it somewhere and add to your classpath. Put it for example, in c:/proj/resources/log4j.properties

In your classpath you simple add .......;c:/proj/resources

# Root logger option
log4j.rootLogger=DEBUG, stdout, file

# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=c:/project/resources/t-output/log4j-application.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

I use the blow function in my GeneralUtils class, check it may be useful

    public String getFieldType(Object o) {
    if (o == null) {
        return "Unable to identify the class name";
    }
    return o.getClass().getName();
}

from file2 import * is making copies. You want to do this:

import file2
print file2.foo
print file2.SomeClass()

A very typical approach to this type of problem is to use row_number():

select t.*
from (select t.*,
             row_number() over (partition by number order by id) as seqnum
      from t
     ) t
where seqnum = 1;

This is more generalizable than using a comparison to the minimum id. For instance, you can get a random row by using order by newid(). You can select 2 rows by using where seqnum <= 2.

I have come up with the same issue, instead of storing images, that eventually overflow the local storage, you can just store the path to the image. something like:

let imagen = ev.target.getAttribute('src');
arrayImagenes.push(imagen);

I’ve made a small gem that can alleviate the need to manually delete associated records in some circumstances.

This gem adds a new option for ActiveRecord associations:

dependent: :delete_recursively

When you destroy a record, all records that are associated using this option will be deleted recursively (i.e. across models), without instantiating any of them.

Note that, just like dependent: :delete or dependent: :delete_all, this new option does not trigger the around/before/after_destroy callbacks of the dependent records.

However, it is possible to have dependent: :destroy associations anywhere within a chain of models that are otherwise associated with dependent: :delete_recursively. The :destroy option will work normally anywhere up or down the line, instantiating and destroying all relevant records and thus also triggering their callbacks.

The script in How to get rid of the white margin in MATLAB's saveas or print outputs does what you want.

Make your figure boundaries tight:

ti = get(gca,'TightInset')
set(gca,'Position',[ti(1) ti(2) 1-ti(3)-ti(1) 1-ti(4)-ti(2)]);

... if you directly do saveas (or print), MATLAB will still add the annoying white space. To get rid of them, we need to adjust the ``paper size":

set(gca,'units','centimeters')
pos = get(gca,'Position');
ti = get(gca,'TightInset');

set(gcf, 'PaperUnits','centimeters');
set(gcf, 'PaperSize', [pos(3)+ti(1)+ti(3) pos(4)+ti(2)+ti(4)]);
set(gcf, 'PaperPositionMode', 'manual');
set(gcf, 'PaperPosition',[0 0 pos(3)+ti(1)+ti(3) pos(4)+ti(2)+ti(4)]);

For those wondering why ipairs doesn't print all the values of the table all the time, here's why (I would comment this, but I don't have enough good boy points).

The function ipairs only works on tables which have an element with the key 1. If there is an element with the key 1, ipairs will try to go as far as it can in a sequential order, 1 -> 2 -> 3 -> 4 etc until it cant find an element with a key that is the next in the sequence. The order of the elements does not matter.

Tables that do not meet those requirements will not work with ipairs, use pairs instead.

Examples:

ipairsCompatable = {"AAA", "BBB", "CCC"}
ipairsCompatable2 = {[1] = "DDD", [2] = "EEE", [3] = "FFF"}
ipairsCompatable3 = {[3] = "work", [2] = "does", [1] = "this"}

notIpairsCompatable = {[2] = "this", [3] = "does", [4] = "not"}
notIpairsCompatable2 = {[2] = "this", [5] = "doesn't", [24] = "either"}

ipairs will go as far as it can with it's iterations but won't iterate over any other element in the table.

kindofIpairsCompatable = {[2] = 2, ["cool"] = "bro", [1] = 1, [3] = 3, [5] = 5 }

When printing these tables, these are the outputs. I've also included pairs outputs for comparison.

ipairs + ipairsCompatable
1       AAA
2       BBB
3       CCC

ipairs + ipairsCompatable2
1       DDD
2       EEE
3       FFF

ipairs + ipairsCompatable3
1       this
2       does
3       work

ipairs + notIpairsCompatable

pairs + notIpairsCompatable
2       this
3       does
4       not

ipairs + notIpairsCompatable2

pairs + notIpairsCompatable2
2       this
5       doesnt
24      either

ipairs + kindofIpairsCompatable
1       1
2       2
3       3

pairs + kindofIpairsCompatable
1       1
2       2
3       3
5       5

const a = {
  foods: {
    dinner: 'Pasta'
  }
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta

Using JSON.stringify and JSON.parse is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.

None of these answers worked for me so Im leaving the code that did work. In my case even after killing the process with .kill() and getting a .poll() return code the process didn't terminate.

Following the subprocess.Popen documentation:

"...in order to cleanup properly a well-behaved application should kill the child process and finish communication..."

proc = subprocess.Popen(...)
try:
    outs, errs = proc.communicate(timeout=15)
except TimeoutExpired:
    proc.kill()
    outs, errs = proc.communicate()

In my case I was missing the proc.communicate() after calling proc.kill(). This cleans the process stdin, stdout ... and does terminate the process.

To catch all possible exceptions, catch BaseException. It's on top of the Exception hierarchy:

Python 3: https://docs.python.org/3.9/library/exceptions.html#exception-hierarchy

Python 2.7: https://docs.python.org/2.7/library/exceptions.html#exception-hierarchy

try:
    something()
except BaseException as error:
    print('An exception occurred: {}'.format(error))

But as other people mentioned, you would usually not need this, only for specific cases.

As pointed out already, most standard implementations of List are serializable. However you have to ensure that the objects referenced/contained within the list are also serializable.

With ECMAScript 6 there is a better way.

You can use computed property names in object property definitions, for example:

var name1 = 'John'; 
var value1 = '42'; 
var name2 = 'Sarah'; 
var value2 = '35';

var ipID = { 
             [name1] : value1, 
             [name2] : value2 
           }

This is equivalent to the following, where you have variables for the property names.

var ipID = { 
             John: '42', 
             Sarah: '35' 
           }

From: jQuery text truncation (read more style)

Try this:

var title = "This is your title";

var shortText = jQuery.trim(title).substring(0, 10)
    .split(" ").slice(0, -1).join(" ") + "...";

• Tested here

And you can also use a plugin:

• jQuery Expander Plugin

As a extension of String

String.prototype.trimToLength = function(m) {
  return (this.length > m) 
    ? jQuery.trim(this).substring(0, m).split(" ").slice(0, -1).join(" ") + "..."
    : this;
};

Use as

"This is your title".trimToLength(10);

While jball's answer is an excellent description of content insets, it doesn't answer the question of when to use it. I'll borrow from his diagrams:

  _|?_cW_?_|_?_
   |       | 
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
   |content|    
-------------?-

That's what you get when you do it, but the usefulness of it only shows when you scroll:

  _|?_cW_?_|_?_
   |content| ? content is still visible
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
  _|_______|___ 
             ?

That top row of content will still be visible because it's still inside the frame of the scroll view. One way to think of the top offset is "how much to shift the content down the scroll view when we're scrolled all the way to the top"

To see a place where this is actually used, look at the build-in Photos app on the iphone. The Navigation bar and status bar are transparent, and the contents of the scroll view are visible underneath. That's because the scroll view's frame extends out that far. But if it wasn't for the content inset, you would never be able to have the top of the content clear that transparent navigation bar when you go all the way to the top.

This is not exactly the answer to the question, but I end up here every time I want to find out how to get my batch file to exit with and error code when a process returns an nonzero code.

So here is the answer to that:

if %ERRORLEVEL% NEQ 0 exit %ERRORLEVEL%

You can use this in settings.json

"javascript.preferences.quoteStyle": "single"

This is similar to aSeptik's answer, but what about this approach? Wrap the CSS code which you want to disable using JavaScript in <noscript> tags. That way if javaScript is off, the CSS :hover will be used, otherwise the JavaScript effect will be used.

Example:

<noscript>
<style type="text/css">
ul#mainFilter a:hover {
  /* some CSS attributes here */
}
</style>
</noscript>
<script type="text/javascript">
$("ul#mainFilter a").hover(
     function(o){ /* ...do your stuff... */ }, 
     function(o){ /* ...do your stuff... */ });
</script>

Expanding on Tony's answer, and also answering Dhaval Ptl's question, to get the true accordion effect and only allow one row to be expanded at a time, an event handler for show.bs.collapse can be added like so:

$('.collapse').on('show.bs.collapse', function () {
    $('.collapse.in').collapse('hide');
});

I modified his example to do this here: http://jsfiddle.net/QLfMU/116/

You need to add the hamcrest-core JAR to the classpath as described here: https://github.com/junit-team/junit4/wiki/Download-and-Install

Here is another way by using UIBezierPath (maybe it's too late ^^) Create a circle and mask UIView with it, as follows:

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
view.backgroundColor = [UIColor blueColor];

CAShapeLayer *shape = [CAShapeLayer layer];
UIBezierPath *path = [UIBezierPath bezierPathWithArcCenter:view.center radius:(view.bounds.size.width / 2) startAngle:0 endAngle:(2 * M_PI) clockwise:YES];
shape.path = path.CGPath;
view.layer.mask = shape;

Using iReport designer 5.6.0, if you wish to compile multiple jrxml files without previewing - go to Tools -> Massive Processing Tool. Select Elaboration Type as "Compile Files", select the folder where all your jrxml reports are stored, and compile them in a batch.

CHARINDEX() searches for a substring within a larger string, and returns the position of the match, or 0 if no match is found

if CHARINDEX('ME',@mainString) > 0
begin
    --do something
end

Edit or from daniels answer, if you're wanting to find a word (and not subcomponents of words), your CHARINDEX call would look like:

CHARINDEX(' ME ',' ' + REPLACE(REPLACE(@mainString,',',' '),'.',' ') + ' ')

(Add more recursive REPLACE() calls for any other punctuation that may occur)

This program in java returns "true" if number is a power of 2 and returns "false" if its not a power of 2

// To check if the given number is power of 2

import java.util.Scanner;

    void solve() {
        while(true) {
//          To eleminate the odd numbers
            if((n%2)!= 0){
                System.out.println("false");
                break;
            }
//  Tracing the number back till 2
            n = n/2;
//  2/2 gives one so condition should be 1
            if(n == 1) {
                System.out.println("true");
                break;
            }
        }

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner in = new Scanner(System.in);
        PowerOfTwo obj = new PowerOfTwo();
        obj.n = in.nextInt();
        obj.solve();

Is it essential that you need a NumPy array? Otherwise you could speed things up by loading the data as a nested list.

def load(fname):
    ''' Load the file using std open'''
    f = open(fname,'r')

    data = []
    for line in f.readlines():
        data.append(line.replace('\n','').split(' '))

    f.close()

    return data

For a text file with 4000x4000 words this is about 10 times faster than loadtxt.

<?php header('Location: /login.php'); ?>

The above php script redirects the user to login.php within the same site

you can do:

adb pull /storage/emulated/0/Android/data//

jQuery serialize gets the value attribute of inputs.

Now how to get checkbox and radio button to work? If you set the click event of the checkbox or radio-button 0 or 1 you will be able to see the changes.

$( "#myform input[type='checkbox']" ).on( "click", function(){
     if ($(this).prop('checked')){
          $(this).attr('value', 1);
     } else {
          $(this).attr('value', 0);
     }
 }); 

 values = $("#myform").serializeArray();

and also when ever you want to set the checkbox with checked status e.g. php

<input type='checkbox' value="<?php echo $product['check']; ?>" checked="<?php echo $product['check']; ?>" />

Roland Bouman's answer is the best, simple Vanilla way. I noticed some attempts at jQ plugs, but they just didn't seem "full" enough to me, so I made my own. The only setback so far has been inability to access dynamically added attrs without directly calling elm.attr('dynamicAttr'). However, this will return all natural attributes of a jQuery element object.

Plugin uses simple jQuery style calling:

$(elm).getAttrs();
// OR
$.getAttrs(elm);

You can also add a second string param for getting just one specific attr. This isn't really needed for one element selection, as jQuery already provides $(elm).attr('name'), however, my version of a plugin allows for multiple returns. So, for instance, a call like

$.getAttrs('*', 'class');

Will result in an array [] return of objects {}. Each object will look like:

{ class: 'classes names', elm: $(elm), index: i } // index is $(elm).index()

<p>Roland Bouman's answer is the best, simple Vanilla way. I noticed some attempts at jQ plugs, but they just didn't seem "full" enough to me, so I made my own. The only setback so far has been inability to access dynamically added attrs without directly calling <code>elm.attr('dynamicAttr')</code>. However, this will return all natural attributes of a jQuery element object.</p>_x000D_
_x000D_
<p>Plugin uses simple jQuery style calling:</p>_x000D_
_x000D_
<pre class="default prettyprint prettyprinted"><code><span class="pln">$</span><span class="pun">(</span><span class="pln">elm</span><span class="pun">).</span><span class="pln">getAttrs</span><span class="pun">();</span><span class="pln">_x000D_

$</span><span class="pun">.</span><span class="pln">getAttrs</span><span class="pun">(</span><span class="pln">elm</span><span class="pun">);</span></code></pre>_x000D_
_x000D_
<p>You can also add a second string param for getting just one specific attr. This isn't really needed for one element selection, as jQuery already provides <code>$(elm).attr('name')</code>, however, my version of a plugin allows for multiple returns. So, for instance, a call like</p>_x000D_
_x000D_
<pre class="default prettyprint prettyprinted"><code><span class="pln">$</span><span class="pun">.</span><span class="pln">getAttrs</span><span class="pun">(</span><span class="str">'*'</span><span class="pun">,</span><span class="pln"> </span><span class="str">'class'</span><span class="pun">);</span></code></pre>_x000D_
_x000D_
<p>Will result in an array <code>[]</code> return of objects <code>{}</code>. Each object will look like:</p>_x000D_

I will show visually the problem, using the great example from James answer and adding the alternative solution.

When you do the follow query, without the FETCH:

Select e from Employee e 
join e.phones p 
where p.areaCode = '613'

You will have the follow results from Employee as you expected:

But when you add the FETCH word on JOIN, this is what happens:

The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416 register when you use WHERE on the FETCH join.

So, to bring all phones and apply the WHERE correctly, you need to have two JOINs: one for the WHERE and another for the FETCH. Like:

Select e from Employee e 
join e.phones p 
join fetch e.phones      //no alias, to not commit the mistake
where p.areaCode = '613'

You dbcontext is in Toombu.DataAccess So you should enable migrations in Toombu.DataAccess.

I know this is an older subject, however Mocking a MVC application for unit tests is something we do on very regular basis.

I just wanted to add my experiences Mocking a MVC 3 application using Moq 4 after upgrading to Visual Studio 2013. None of the unit tests were working in debug mode and the HttpContext was showing "could not evaluate expression" when trying to peek at the variables.

Turns out visual studio 2013 has issues evaluating some objects. To get debugging mocked web applications working again, I had to check the "Use Managed Compatibility Mode" in Tools=>Options=>Debugging=>General settings.

I generally do something like this:

public static class FakeHttpContext
{
    public static void SetFakeContext(this Controller controller)
    {

        var httpContext = MakeFakeContext();
        ControllerContext context =
        new ControllerContext(
        new RequestContext(httpContext,
        new RouteData()), controller);
        controller.ControllerContext = context;
    }


    private static HttpContextBase MakeFakeContext()
    {
        var context = new Mock<HttpContextBase>();
        var request = new Mock<HttpRequestBase>();
        var response = new Mock<HttpResponseBase>();
        var session = new Mock<HttpSessionStateBase>();
        var server = new Mock<HttpServerUtilityBase>();
        var user = new Mock<IPrincipal>();
        var identity = new Mock<IIdentity>();

        context.Setup(c=> c.Request).Returns(request.Object);
        context.Setup(c=> c.Response).Returns(response.Object);
        context.Setup(c=> c.Session).Returns(session.Object);
        context.Setup(c=> c.Server).Returns(server.Object);
        context.Setup(c=> c.User).Returns(user.Object);
        user.Setup(c=> c.Identity).Returns(identity.Object);
        identity.Setup(i => i.IsAuthenticated).Returns(true);
        identity.Setup(i => i.Name).Returns("admin");

        return context.Object;
    }


}

And initiating the context like this

FakeHttpContext.SetFakeContext(moController);

And calling the Method in the controller straight forward

long lReportStatusID = -1;
var result = moController.CancelReport(lReportStatusID);

I am try to convert Object type variable into string using this line of code

try this to convert object value to string:

Java Code

 Object dataobject=value;
    //convert object into String  
     String convert= String.valueOf(dataobject);

I am using following:

    using System.Web.Script.Serialization;       

    ...

    public static T ParseResponse<T>(string data)
    {
        return new JavaScriptSerializer().Deserialize<T>(data);
    }

A return value of the previously executed process.

10.4 Getting the return value of a program

In bash, the return value of a program is stored in a special variable called $?.

This illustrates how to capture the return value of a program, I assume that the directory dada does not exist. (This was also suggested by mike)

        #!/bin/bash
        cd /dada &> /dev/null
        echo rv: $?
        cd $(pwd) &> /dev/null
        echo rv: $?

See Bash Programming Manual for more details.

I found a way around it using tuckey's urlrewritefilter. Please feel free to give a better answer if you have one!

In web.xml:

<filter>
    <filter-name>UrlRewriteFilter</filter-name>
    <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>UrlRewriteFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

  <servlet>
    <servlet-name>app</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>app</servlet-name>
    <url-pattern>/app/*</url-pattern>
  </servlet-mapping>

In urlrewrite.xml:

<urlrewrite default-match-type="wildcard">
<rule>
    <from>/</from>
    <to>/app/</to>
</rule>
<rule match-type="regex">
    <from>^([^\.]+)$</from>
    <to>/app/$1</to>
</rule>
<outbound-rule>
    <from>/app/**</from>
    <to>/$1</to>
</outbound-rule>    

This means that any uri with a '.' in it (like style.css for example) won't be re-written.

For us, everything was fine, emails are very small and not a lot of them are sent and sudently it gave this error. It appeared that a technicien installed ASTARO which was preventing email to be sent. and we were getting this error so yes the error is a bit cryptic but I hope this could help others.

Additionally, return values are compatible with asynchronous design paradigms.

You cannot designate a function "async" if it uses ref or out parameters.

In summary, Return Values allow method chaining, cleaner syntax (by eliminating the necessity for the caller to declare additional variables), and allow for asynchronous designs without the need for substantial modification in the future.

It was particular for me. I am sending a header named 'SESSIONHASH'. No problem for Chrome and Opera, but Firefox also wants this header in the list "Access-Control-Allow-Headers". Otherwise, Firefox will throw the CORS error.

After testing and a few days wait for feedback, I'll svn-commit the following whole new function in xlrd's xldate module ... note that it won't be available to the diehards still running Python 2.1 or 2.2.

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

Doing a 302 will typically cause clients to convert a POST to a GET request.

Seemed to be a no brainer; the WCF service should be enabled using Programs and Features -> Turn Windows features on or off in the Control Panel. Go to .NET Framework Advanced Services -> WCF Services and enable HTTP Activation as described in this blog post on mdsn.

From the command prompt (as admin), you can run:

C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation
C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation45

If you get an error then use the below

C:\> DISM /Online /Enable-Feature /all /FeatureName:WCF-HTTP-Activation
C:\> DISM /Online /Enable-Feature /all /FeatureName:WCF-HTTP-Activation45

Dateadd(datepart,number,date)

You should use it like this:

select DATEADD(day,360,getdate())

Then you will find the same date but different year.

It does have to be wrapped in an <xsl:choose> since it's a when. And lowercase the "and".

<xsl:choose>
   <xsl:when test="4 &lt; 5 and 1 &lt; 2" >
   <!-- do something -->
   </xsl:when>
   <xsl:otherwise>
   <!-- do something else -->
   </xsl:otherwise>
</xsl:choose>

using C++ 14:

#include <string>
#include <vector>


std::vector<std::string> listbox;
...
std::vector<std::string> strarr {"ram","mohan","sita"};    
for (const auto &str : strarr)
{
    listbox.push_back(str);
}

In market client on phones at least featured apps with high ratings get to display the promotional graphic.

This is the one that shows up on top even before you start searching the market for a specific app.

See this answer from Android market forum.

Edited: One of the google employee gives some clarifications here

Update: Both links above are now broken but the detailed information can be found here

Selected applications have the ability to be featured atop their respective categories. This is not a guaranteed feature, but uploading promotional graphics is something that we recommend.

From http://pmob.co.uk/pob/centred-float.htm:

The premise is simple and basically just involves a widthless float wrapper that is floated to the left and then shifted off screen to the left width position:relative; left:-50%. Next the nested inner element is reversed and a relative position of +50% is applied. This has the effect of placing the element dead in the center. Relative positioning maintains the flow and allows other content to flow underneath.

Code

#buttons{
    float:right;
    position:relative;
    left:-50%;
    text-align:left;
}
#buttons ul{
    list-style:none;
    position:relative;
    left:50%;
}

#buttons li{float:left;position:relative;}/* ie needs position:relative here*/

#buttons a{
    text-decoration:none;
    margin:10px;
    background:red;
    float:left;
    border:2px outset blue;
    color:#fff;
    padding:2px 5px;
    text-align:center;
    white-space:nowrap;
}
#buttons a:hover{ border:2px inset blue;color:red;background:#f2f2f2;}
#content{overflow:hidden}/* hide horizontal scrollbar*/

<div id="buttons">
    <ul>
        <li><a href="#">Button 1</a></li>
        <li><a href="#">Button 2's a bit longer</a></li>
        <li><a href="#">Butt 3</a></li>
        <li><a href="#">Button 4</a></li>
    </ul>
</div>

Note need root than:

• adb root
• adb pull /data/data/com.google.android.apps.nexuslauncher/databases/launcher.db launcher.db

If you load the document in Chrome, the Developer|Elements view will show you the HTML as fiddled by your JS code. It's not directly HTML text and you have to open (unfold) any elements of interest, but you effectively get to inspect the generated HTML.

To escape backslashes that cause problems for JSON data I use this function.

//escape backslash to avoid errors
var escapeJSON = function(str) {
    return str.replace(/\\/g,'\\');
};

I'm afraid it's the best solution that I can think of. But you can use reserve() to pre-allocate the minimum required memory in advance to speed up things a bit. You'll end up with a new string that will probably be shorter but that takes up the same amount of memory, but you'll avoid reallocations.

EDIT: Depending on your situation, this may incur less overhead than jumbling characters around.

You should try different approaches and see what is best for you: you might not have any performance issues at all.

I think there are applications where "hash" is faster than comparing byte by byte. If you need to compare a file with others or have a thumbnail of a photo that can change. It depends on where and how it is using.

private bool CompareFilesByte(string file1, string file2)
{
    using (var fs1 = new FileStream(file1, FileMode.Open))
    using (var fs2 = new FileStream(file2, FileMode.Open))
    {
        if (fs1.Length != fs2.Length) return false;
        int b1, b2;
        do
        {
            b1 = fs1.ReadByte();
            b2 = fs2.ReadByte();
            if (b1 != b2 || b1 < 0) return false;
        }
        while (b1 >= 0);
    }
    return true;
}

private string HashFile(string file)
{
    using (var fs = new FileStream(file, FileMode.Open))
    using (var reader = new BinaryReader(fs))
    {
        var hash = new SHA512CryptoServiceProvider();
        hash.ComputeHash(reader.ReadBytes((int)file.Length));
        return Convert.ToBase64String(hash.Hash);
    }
}

private bool CompareFilesWithHash(string file1, string file2)
{
    var str1 = HashFile(file1);
    var str2 = HashFile(file2);
    return str1 == str2;
}

Here, you can get what is the fastest.

var sw = new Stopwatch();
sw.Start();
var compare1 = CompareFilesWithHash(receiveLogPath, logPath);
sw.Stop();
Debug.WriteLine(string.Format("Compare using Hash {0}", sw.ElapsedTicks));
sw.Reset();
sw.Start();
var compare2 = CompareFilesByte(receiveLogPath, logPath);
sw.Stop();
Debug.WriteLine(string.Format("Compare byte-byte {0}", sw.ElapsedTicks));

Optionally, we can save the hash in a database.

Hope this can help

Well i had the same problem what when i added the following code within the tag my problem fixed :

I hope this can help you guys!

NSDate and the timeIntervalSince* methods will return a NSTimeInterval which is a double with sub-millisecond accuracy. NSTimeInterval is in seconds, but it uses the double to give you greater precision.

In order to calculate millisecond time accuracy, you can do:

// Get a current time for where you want to start measuring from
NSDate *date = [NSDate date];

// do work...

// Find elapsed time and convert to milliseconds
// Use (-) modifier to conversion since receiver is earlier than now
double timePassed_ms = [date timeIntervalSinceNow] * -1000.0;

Documentation on timeIntervalSinceNow.

There are many other ways to calculate this interval using NSDate, and I would recommend looking at the class documentation for NSDate which is found in NSDate Class Reference.

Normally you are going to do this in your template with FormGroup, Reactive Forms, etc...

    this.myForm = this.fb.group({
      title: ['', Validators.required],
      description: ['', Validators.required],
      isPublished: ['false',Validators.required]
    });

You'll need to check menuItem.getItemId() against android.R.id.home in the onOptionsItemSelected method

Because os.path.abspath = os.path.dirname + os.path.basename does not hold. we rather have

os.path.dirname(filename) + os.path.basename(filename) == filename

Both dirname() and basename() only split the passed filename into components without taking into account the current directory. If you want to also consider the current directory, you have to do so explicitly.

To get the dirname of the absolute path, use

os.path.dirname(os.path.abspath(__file__))

Since nobody did cover this question of the OP yet:

What I wanted to do:

Make a python module install-able with "pip install ..."

Here is an absolute minimal example, showing the basic steps of preparing and uploading your package to PyPI using setuptools and twine.

This is by no means a substitute for reading at least the tutorial, there is much more to it than covered in this very basic example.

Creating the package itself is already covered by other answers here, so let us assume we have that step covered and our project structure like this:

.
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

In order to use setuptools for packaging, we need to add a file setup.py, this goes into the root folder of our project:

.
+-- setup.py
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

At the minimum, we specify the metadata for our package, our setup.py would look like this:

from setuptools import setup

setup(
    name='hellostackoverflow',
    version='0.0.1',
    description='a pip-installable package example',
    license='MIT',
    packages=['hellostackoverflow'],
    author='Benjamin Gerfelder',
    author_email='[email protected]',
    keywords=['example'],
    url='https://github.com/bgse/hellostackoverflow'
)

Since we have set license='MIT', we include a copy in our project as LICENCE.txt, alongside a readme file in reStructuredText as README.rst:

.
+-- LICENCE.txt
+-- README.rst
+-- setup.py
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

At this point, we are ready to go to start packaging using setuptools, if we do not have it already installed, we can install it with pip:

pip install setuptools

In order to do that and create a source distribution, at our project root folder we call our setup.py from the command line, specifying we want sdist:

python setup.py sdist

This will create our distribution package and egg-info, and result in a folder structure like this, with our package in dist:

.
+-- dist/
+-- hellostackoverflow.egg-info/
+-- LICENCE.txt
+-- README.rst
+-- setup.py
+-- hellostackoverflow/
    +-- __init__.py
    +-- hellostackoverflow.py

At this point, we have a package we can install using pip, so from our project root (assuming you have all the naming like in this example):

pip install ./dist/hellostackoverflow-0.0.1.tar.gz

If all goes well, we can now open a Python interpreter, I would say somewhere outside our project directory to avoid any confusion, and try to use our shiny new package:

Python 3.5.2 (default, Sep 14 2017, 22:51:06) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from hellostackoverflow import hellostackoverflow
>>> hellostackoverflow.greeting()
'Hello Stack Overflow!'

Now that we have confirmed the package installs and works, we can upload it to PyPI.

Since we do not want to pollute the live repository with our experiments, we create an account for the testing repository, and install twine for the upload process:

pip install twine

Now we're almost there, with our account created we simply tell twine to upload our package, it will ask for our credentials and upload our package to the specified repository:

twine upload --repository-url https://test.pypi.org/legacy/ dist/*

We can now log into our account on the PyPI test repository and marvel at our freshly uploaded package for a while, and then grab it using pip:

pip install --index-url https://test.pypi.org/simple/ hellostackoverflow

As we can see, the basic process is not very complicated. As I said earlier, there is a lot more to it than covered here, so go ahead and read the tutorial for more in-depth explanation.

You can just go for String replace method.-

line1 = line1.replace("\"", "");

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

On Ubuntu none of the keys (Ctrl+F11/F12 or numpad 7/numpad 9) worked for me. But I can rotate the emulator sending the keys with xdotool.

For example for a VM named "Galaxy_Nexus" I can rotate the emulator with:

xdotool search --name "Galaxy" key "ctrl_L+F11"

A small correction to the original answer - delete also generates significant amounts of redo (as undo is itself protected by redo). This can be seen from autotrace output:

1. Using the x509 module
openssl x509 ...
...

2 Using the ca module
openssl ca ...
...

You are missing the prelude to those commands.

This is a two-step process. First you set up your CA, and then you sign an end entity certificate (a.k.a server or user). Both of the two commands elide the two steps into one. And both assume you have a an OpenSSL configuration file already setup for both CAs and Server (end entity) certificates.

First, create a basic configuration file:

$ touch openssl-ca.cnf

Then, add the following to it:

HOME            = .
RANDFILE        = $ENV::HOME/.rnd

subjectKeyIdentifier   = hash

keyUsage               = keyCertSign, cRLSign

The fields above are taken from a more complex openssl.cnf (you can find it in /usr/lib/openssl.cnf), but I think they are the essentials for creating the CA certificate and private key.

Tweak the fields above to suit your taste. The defaults save you the time from entering the same information while experimenting with configuration file and command options.

I omitted the CRL-relevant stuff, but your CA operations should have them. See openssl.cnf and the related crl_ext section.

Then, execute the following. The -nodes omits the password or passphrase so you can examine the certificate. It's a really bad idea to omit the password or passphrase.

$ openssl req -x509 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

After the command executes, cacert.pem will be your certificate for CA operations, and cakey.pem will be the private key. Recall the private key does not have a password or passphrase.

You can dump the certificate with the following.

$ openssl x509 -in cacert.pem -text -noout

For part two, I'm going to create another configuration file that's easily digestible. First, touch the openssl-server.cnf (you can make one of these for user certificates also).

$ touch openssl-server.cnf

Then open it, and add the following.

HOME            = .
RANDFILE        = $ENV::HOME/.rnd

####################################################################
[ req ]
default_bits       = 2048

string_mask        = utf8only

####################################################################

countryName         = Country Name (2 letter code)
countryName_default = US

stateOrProvinceName         = State or Province Name (full name)
stateOrProvinceName_default = MD

localityName         = Locality Name (eg, city)
localityName_default = Baltimore

organizationName            = Organization Name (eg, company)
organizationName_default    = Test Server, Limited

commonName           = Common Name (e.g. server FQDN or YOUR name)
commonName_default   = Test Server

emailAddress         = Email Address
emailAddress_default = [email protected]

####################################################################
[ server_req_extensions ]

subjectKeyIdentifier = hash
basicConstraints     = CA:FALSE
keyUsage             = digitalSignature, keyEncipherment
subjectAltName       = @alternate_names
nsComment            = "OpenSSL Generated Certificate"

####################################################################
[ alternate_names ]

DNS.2  = www.example.com
DNS.3  = mail.example.com
DNS.4  = ftp.example.com

If you are developing and need to use your workstation as a server, then you may need to do the following for Chrome. Otherwise Chrome may complain a Common Name is invalid (ERR_CERT_COMMON_NAME_INVALID). I'm not sure what the relationship is between an IP address in the SAN and a CN in this instance.

# IPv4 localhost
IP.1     = 127.0.0.1

# IPv6 localhost
IP.2     = ::1

Then, create the server certificate request. Be sure to omit -x509*. Adding -x509 will create a certificate, and not a request.

$ openssl req -config openssl-server.cnf -newkey rsa:2048 -sha256 -nodes -out servercert.csr -outform PEM

After this command executes, you will have a request in servercert.csr and a private key in serverkey.pem.

And you can inspect it again.

$ openssl req -text -noout -verify -in servercert.csr

Next, you have to sign it with your CA.

You are almost ready to sign the server's certificate by your CA. The CA's openssl-ca.cnf needs two more sections before issuing the command.

First, open openssl-ca.cnf and add the following two sections.

####################################################################
[ signing_policy ]
countryName            = optional
stateOrProvinceName    = optional
localityName           = optional
organizationName       = optional
organizationalUnitName = optional
commonName             = supplied
emailAddress           = optional

####################################################################
[ signing_req ]
subjectKeyIdentifier   = hash
authorityKeyIdentifier = keyid,issuer
basicConstraints       = CA:FALSE
keyUsage               = digitalSignature, keyEncipherment

Second, add the following to the [ CA_default ] section of openssl-ca.cnf. I left them out earlier, because they can complicate things (they were unused at the time). Now you'll see how they are used, so hopefully they will make sense.

base_dir      = .
certificate   = $base_dir/cacert.pem   # The CA certifcate
private_key   = $base_dir/cakey.pem    # The CA private key
new_certs_dir = $base_dir              # Location for new certs after signing
database      = $base_dir/index.txt    # Database index file
serial        = $base_dir/serial.txt   # The current serial number

unique_subject = no  # Set to 'no' to allow creation of
                     # several certificates with same subject.

Third, touch index.txt and serial.txt:

$ touch index.txt
$ echo '01' > serial.txt

Then, perform the following:

$ openssl ca -config openssl-ca.cnf -policy signing_policy -extensions signing_req -out servercert.pem -infiles servercert.csr

You should see similar to the following:

Using configuration from openssl-ca.cnf
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName           :PRINTABLE:'US'
stateOrProvinceName   :ASN.1 12:'MD'
localityName          :ASN.1 12:'Baltimore'
commonName            :ASN.1 12:'Test CA'
emailAddress          :IA5STRING:'[email protected]'
Certificate is to be certified until Oct 20 16:12:39 2016 GMT (1000 days)
Sign the certificate? [y/n]:Y

1 out of 1 certificate requests certified, commit? [y/n]Y
Write out database with 1 new entries
Data Base Updated

After the command executes, you will have a freshly minted server certificate in servercert.pem. The private key was created earlier and is available in serverkey.pem.

Finally, you can inspect your freshly minted certificate with the following:

$ openssl x509 -in servercert.pem -text -noout

Earlier, you added the following to CA_default: copy_extensions = copy. This copies extension provided by the person making the request.

If you omit copy_extensions = copy, then your server certificate will lack the Subject Alternate Names (SANs) like www.example.com and mail.example.com.

If you use copy_extensions = copy, but don't look over the request, then the requester might be able to trick you into signing something like a subordinate root (rather than a server or user certificate). Which means he/she will be able to mint certificates that chain back to your trusted root. Be sure to verify the request with openssl req -verify before signing.

If you omit unique_subject or set it to yes, then you will only be allowed to create one certificate under the subject's distinguished name.

unique_subject = yes            # Set to 'no' to allow creation of
                                # several ctificates with same subject.

Trying to create a second certificate while experimenting will result in the following when signing your server's certificate with the CA's private key:

Sign the certificate? [y/n]:Y
failed to update database
TXT_DB error number 2

So unique_subject = no is perfect for testing.

If you want to ensure the Organizational Name is consistent between self-signed CAs, Subordinate CA and End-Entity certificates, then add the following to your CA configuration files:

[ policy_match ]
organizationName = match

If you want to allow the Organizational Name to change, then use:

[ policy_match ]
organizationName = supplied

There are other rules concerning the handling of DNS names in X.509/PKIX certificates. Refer to these documents for the rules:

• RFC 5280, Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile
• RFC 6125, Representation and Verification of Domain-Based Application Service Identity within Internet Public Key Infrastructure Using X.509 (PKIX) Certificates in the Context of Transport Layer Security (TLS)
• RFC 6797, Appendix A, HTTP Strict Transport Security (HSTS)
• RFC 7469, Public Key Pinning Extension for HTTP
• CA/Browser Forum Baseline Requirements
• CA/Browser Forum Extended Validation Guidelines

RFC 6797 and RFC 7469 are listed, because they are more restrictive than the other RFCs and CA/B documents. RFC's 6797 and 7469 do not allow an IP address, either.

if you have two divs, you can use this to align the divs next to each other in the same row:

#keyword {_x000D_
    float:left;_x000D_
    margin-left:250px;_x000D_
    position:absolute;_x000D_
}_x000D_
_x000D_
#bar {_x000D_
    text-align:center;_x000D_
}

<div id="keyword">_x000D_
Keywords:_x000D_
</div>_x000D_
<div id="bar">_x000D_
    <input type = textbox   name ="keywords" value="" onSubmit="search()" maxlength=40>_x000D_
    <input type = button   name="go" Value="Go ahead and find" onClick="search()">_x000D_
</div>

Below code may help you to achieve session attribution inside java script:

var name = '<%= session.getAttribute("username") %>';

I lost some days with this problem.... until I found that in some file I was importing one static file, a built file. It make the build to never end. Something like:

import PropTypes from "../static/build/prop-types"; 

Fixing to the real source solved all the problem.

Sharing my solution. :)

If we need to move from one component to another service then we have to define that service into app.module providers array.

Put the URLs into an HTML table, load the HTML page into a browser, copy the contents of that page, paste into Excel. At this point the URLs are preserved as active links.

Solution was proposed on http://answers.microsoft.com/en-us/mac/forum/macoffice2008-macexcel/how-to-copy-and-paste-to-mac-excel-2008-a-list-of/c5fa2890-acf5-461d-adb5-32480855e11e by (Jim Gordon Mac MVP)[http://answers.microsoft.com/en-us/profile/75a2b744-a259-49bb-8eb1-7db61dae9e78]

I found that it worked.

I had these URLs:

I put them into an HTML file (links.html) like this:

Many answer above are correct but same time convoluted with other aspects of authN/authZ. What actually resolves the exception in question is this line:

services.AddScheme<YourAuthenticationOptions, YourAuthenticationHandler>(YourAuthenticationSchemeName, options =>
    {
        options.YourProperty = yourValue;
    })

Reading the Spark documentation I found an easier solution.

Since version 1.4 of spark there is a function drop(col) which can be used in pyspark on a dataframe.

You can use it in two ways

1. df.drop('age').collect()
2. df.drop(df.age).collect()

A SimpleDateFormat, as its name indicates, formats Dates. Not a Calendar. So, if you want to format a GregorianCalendar using a SimpleDateFormat, you must convert the Calendar to a Date first:

dateFormat.format(calendar.getTime());

And what you see printed is the toString() representation of the calendar. It's intended usage is debugging. It's not intended to be used to display a date in a GUI. For that, use a (Simple)DateFormat.

Finally, to convert from a String to a Date, you should also use a (Simple)DateFormat (its parse() method), rather than splitting the String as you're doing. This will give you a Date object, and you can create a Calendar from the Date by instanciating it (Calendar.getInstance()) and setting its time (calendar.setTime()).

My advice would be: Googling is not the solution here. Reading the API documentation is what you need to do.

Center x = x + 1/2 of width

Center y = y + 1/2 of height 

If you know the width and height already then you only need one set of coordinates.

Cocoa has couple of methods for this:

in NSDate

– isEqualToDate:  
– earlierDate:  
– laterDate:  
– compare:

When you use - (NSComparisonResult)compare:(NSDate *)anotherDate ,you get back one of these:

The receiver and anotherDate are exactly equal to each other, NSOrderedSame
The receiver is later in time than anotherDate, NSOrderedDescending
The receiver is earlier in time than anotherDate, NSOrderedAscending.

example:

NSDate * now = [NSDate date];
NSDate * mile = [[NSDate alloc] initWithString:@"2001-03-24 10:45:32 +0600"];
NSComparisonResult result = [now compare:mile];

NSLog(@"%@", now);
NSLog(@"%@", mile);

switch (result)
{
    case NSOrderedAscending: NSLog(@"%@ is in future from %@", mile, now); break;
    case NSOrderedDescending: NSLog(@"%@ is in past from %@", mile, now); break;
    case NSOrderedSame: NSLog(@"%@ is the same as %@", mile, now); break;
    default: NSLog(@"erorr dates %@, %@", mile, now); break;
}

[mile release];

I had the same issue, but I found a good solution here: Stop caching for PHP 5.5.3 in MAMP

Basically find the php.ini file and comment out the OPCache lines. I hope this alternative answer helps others else out as well.

The cleanest solution is to use the django-model-utils library:

from model_utils import Choices

class Article(models.Model):
    STATUS = Choices('draft', 'published')
    status = models.CharField(choices=STATUS, default=STATUS.draft, max_length=20)

Here's something that might be interesting for developers hacking (minified or obfuscated) JavaScript more frequently.

You can build your own CLI JavaScript beautifier in under 5 mins and have it handy on the command-line. You'll need Mozilla Rhino, JavaScript file of some of the JS beautifiers available online, small hack and a script file to wrap it all up.

I wrote an article explaining the procedure: Command-line JavaScript beautifier implemented in JavaScript.

This will help you add the divider height.

 getListView().setDividerHeight(10)

If you want to add a custom view, you can add a small view in the listView item layout itself.

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

var str = "This is a single quote: ' and so is this: '";
console.log(str);

var replaced = str.replace(/'/g, "\\'");
console.log(replaced);

Gives you:

This is a single quote: ' and so is this: '
This is a single quote: \' and so is this: \'

I think the simplest way would be

 return new Friend[0];

The requirements of the return are merely that the method return an object which implements IEnumerable<Friend>. The fact that under different circumstances you return two different kinds of objects is irrelevant, as long as both implement IEnumerable.

Check if have a python interpreter alive in any of the terminal windows. If so kill it and try sudo pip which worked for me.

You're missing a GROUP BY clause:

SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.

You can use property dangerouslySetInnerHTML, like this

const Component = React.createClass({_x000D_
  iframe: function () {_x000D_
    return {_x000D_
      __html: this.props.iframe_x000D_
    }_x000D_
  },_x000D_
_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <div dangerouslySetInnerHTML={ this.iframe() } />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_
  <Component iframe={iframe} />,_x000D_
  document.getElementById('container')_x000D_
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="container"></div>

also, you can copy all attributes from the string(based on the question, you get iframe as a string from a server) which contains <iframe> tag and pass it to new <iframe> tag, like that

/**_x000D_
 * getAttrs_x000D_
 * returns all attributes from TAG string_x000D_
 * @return Object_x000D_
 */_x000D_
const getAttrs = (iframeTag) => {_x000D_
  var doc = document.createElement('div');_x000D_
  doc.innerHTML = iframeTag;_x000D_
_x000D_
  const iframe = doc.getElementsByTagName('iframe')[0];_x000D_
  return [].slice_x000D_
    .call(iframe.attributes)_x000D_
    .reduce((attrs, element) => {_x000D_
      attrs[element.name] = element.value;_x000D_
      return attrs;_x000D_
    }, {});_x000D_
}_x000D_
_x000D_
const Component = React.createClass({_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <iframe {...getAttrs(this.props.iframe) } />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_

In android ,if you are working with hex, you can try okio.

simple usage:

byte[] bytes = ByteString.decodeHex("c000060000").toByteArray();

and result will be

[-64, 0, 6, 0, 0]

Roughly:-

var accounts = new Dictionary<string, double>();

// Initialise to zero...

accounts["Fred"] = 0;
accounts["George"] = 0;
accounts["Fred"] = 0;

// Add cash.
accounts["Fred"] += 4.56;
accounts["George"] += 1.00;
accounts["Fred"] += 1.00;

Console.WriteLine("Fred owes me ${0}", accounts["Fred"]);

I have just tried that if you use SoapUI (5.4.x) and use Apache CXF tool to generate java code, put javax.xml.accessExternalSchema = all in YOUR_JDK/jre/lib/jaxp.properties file also works.

[[UINavigationBar appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];

It is all dependent on how you commit.

For example:

git commit -am "Some message"

will use your ~\.gitconfig username. In other words, if you open that file you should see a line that looks like this:

[user]
    email = [email protected]

That would be the email you want to change. If your doing a pull request through Bitbucket or Github etc. you would be whoever you're logged in as.

You can use WEBRTC but unfortunately it is not supported by all web browsers. BELOW IS THE LINK TO SHOW WHICH BROWSERS supports it http://caniuse.com/stream

And this link gives you an idea of how you can access it(sample code). http://www.html5rocks.com/en/tutorials/getusermedia/intro/

TypeScript does something similar to what less or sass does for CSS. They are super sets of it, which means that every JS code you write is valid TypeScript code. Plus you can use the other goodies that it adds to the language, and the transpiled code will be valid js. You can even set the JS version that you want your resulting code on.

Currently TypeScript is a super set of ES2015, so might be a good choice to start learning the new js features and transpile to the needed standard for your project.

You can't wait() on an object unless the current thread owns that object's monitor. To do that, you must synchronize on it:

class Runner implements Runnable
{
  public void run()
  {
    try
    {
      synchronized(Main.main) {
        Main.main.wait();
      }
    } catch (InterruptedException e) {}
    System.out.println("Runner away!");
  }
}

The same rule applies to notify()/notifyAll() as well.

The Javadocs for wait() mention this:

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Throws:

IllegalMonitorStateException – if the current thread is not the owner of this object's monitor.

And from notify():

A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

ast.literal_eval (located in ast.py) parses the tree with ast.parse first, then it evaluates the code with quite an ugly recursive function, interpreting the parse tree elements and replacing them with their literal equivalents. Unfortunately the code is not at all expandable, so to add Decimal to the code you need to copy all the code and start over.

For a slightly easier approach, you can use ast.parse module to parse the expression, and then the ast.NodeVisitor or ast.NodeTransformer to ensure that there is no unwanted syntax or unwanted variable accesses. Then compile with compile and eval to get the result.

The code is a bit different from literal_eval in that this code actually uses eval, but in my opinion is simpler to understand and one does not need to dig too deep into AST trees. It specifically only allows some syntax, explicitly forbidding for example lambdas, attribute accesses (foo.__dict__ is very evil), or accesses to any names that are not deemed safe. It parses your expression fine, and as an extra I also added Num (float and integer), list and dictionary literals.

Also, works the same on 2.7 and 3.3

import ast
import decimal

source = "(Decimal('11.66985'), Decimal('1e-8'),"\
    "(1,), (1,2,3), 1.2, [1,2,3], {1:2})"

tree = ast.parse(source, mode='eval')

# using the NodeTransformer, you can also modify the nodes in the tree,
# however in this example NodeVisitor could do as we are raising exceptions
# only.
class Transformer(ast.NodeTransformer):
    ALLOWED_NAMES = set(['Decimal', 'None', 'False', 'True'])
    ALLOWED_NODE_TYPES = set([
        'Expression', # a top node for an expression
        'Tuple',      # makes a tuple
        'Call',       # a function call (hint, Decimal())
        'Name',       # an identifier...
        'Load',       # loads a value of a variable with given identifier
        'Str',        # a string literal

        'Num',        # allow numbers too
        'List',       # and list literals
        'Dict',       # and dicts...
    ])

    def visit_Name(self, node):
        if not node.id in self.ALLOWED_NAMES:
            raise RuntimeError("Name access to %s is not allowed" % node.id)

        # traverse to child nodes
        return self.generic_visit(node)

    def generic_visit(self, node):
        nodetype = type(node).__name__
        if nodetype not in self.ALLOWED_NODE_TYPES:
            raise RuntimeError("Invalid expression: %s not allowed" % nodetype)

        return ast.NodeTransformer.generic_visit(self, node)


transformer = Transformer()

# raises RuntimeError on invalid code
transformer.visit(tree)

# compile the ast into a code object
clause = compile(tree, '<AST>', 'eval')

# make the globals contain only the Decimal class,
# and eval the compiled object
result = eval(clause, dict(Decimal=decimal.Decimal))

print(result)

It tells the browser to read the css file as UTF-8. This is handy if your CSS contains unicode characters and not only ASCII.

Using it in the meta tag is fine, but only for pages that include that meta tag.

Read about the rules for character set resolution of CSS files at the w3c spec for CSS 2.

The original code is mostly there, but you need btn-groups around each button. In Bootstrap 3 you can use a btn-toolbar and a btn-group to get the job done; I haven't done BS4 but it has similar constructs.

<div class="btn-toolbar" role="toolbar">
  <div class="btn-group" role="group">
    <button class="btn btn-default">Button 1</button>
  </div>
  <div class="btn-group" role="group">
    <button class="btn btn-default">Button 2</button>
  </div>
</div>

This will work!

$(document).ready(function ()
    {
        $.ajax(
            {
            type: 'POST',
            url: "/Home/MethodName",
            success: function (data) {
                //data is the string that the method returns in a json format, but in string
                var jsonData = JSON.parse(data); //This converts the string to json

                for (var i = 0; i < jsonData.length; i++) //The json object has lenght
                {
                    var object = jsonData[i]; //You are in the current object
                    $('#olListId').append('<li class="someclass>' + object.Atributte  + '</li>'); //now you access the property.

                }

                /* JSON EXAMPLE
                [{ "Atributte": "value" }, 
                { "Atributte": "value" }, 
                { "Atributte": "value" }]
                */
            }
        });
    });

The main thing about this is using the property exactly the same as the attribute of the JSON key-value pair.

Given the fact that you can switch to origin/master (though in detached state) while having your network cable unplugged, it must be a local representation of the master branch at origin.

In order to use nslookup, host or gethostbyname() then the target's name will need to be registered with DNS or statically defined in the hosts file on the machine running your program. Yes, you could connect to the target with SSH or some other application and query it directly, but for a generic solution you'll need some sort of DNS entry for it.

Really, I tested saving values like 'é' and 'e' in column with unique index and they cause duplicate error on both 'utf8_unicode_ci' and 'utf8_general_ci'. You can save them only in 'utf8_bin' collated column.

And mysql docs (in http://dev.mysql.com/doc/refman/5.7/en/charset-applications.html) suggest into its examples set 'utf8_general_ci' collation.

[mysqld]

    echo "Found matches:<br />";
    echo implode("<br />", $matches[0]);
} else {
    echo "No matches found";

It has been almost 8 years since the question was asked, but I will venture an answer not previously given. The OP said this doesn't work:

action="javascript:simpleCart.checkout()"

And the OP said that this code continued to fail despite trying all the good advice he got. So I will venture a guess. The action is calling checkout() as a static method of the simpleCart class; but maybe checkout() is actually an instance member, and not static. It depends how he defined checkout().

By the way, simpleCart is presumably a class name, and by convention class names have an initial capital letter, so let's use that convention, here. Let's use the name SimpleCart.

Here is some sample code that illustrates defining checkout() as an instance member. This was the correct way to do it, prior to ECMA-6:

function SimpleCart() {
    ...
}
SimpleCart.prototype.checkout = function() { ... };

Many people have used a different technique, as illustrated in the following. This was popular, and it worked, but I advocate against it, because instances are supposed to be defined on the prototype, just once, while the following technique defines the member on this and does so repeatedly, with every instantiation.

function SimpleCart() {
    ...
    this.checkout = function() { ... };
}

And here is an instance definition in ECMA-6, using an official class:

class SimpleCart {
    constructor() { ... }
    ...
    checkout()    { ... }
}

Compare to a static definition in ECMA-6. The difference is just one word:

class SimpleCart {
    constructor() { ... }
    ...
    static checkout()    { ... }
}

And here is a static definition the old way, pre-ECMA-6. Note that the checkout() method is defined outside of the function. It is a member of the function object, not the prototype object, and that's what makes it static.

function SimpleCart() {
    ...
}
SimpleCart.checkout = function() { ... };

Because of the way it is defined, a static function will have a different concept of what the keyword this references. Note that instance member functions are called using the this keyword:

this.checkout();

Static member functions are called using the class name:

SimpleCart.checkout();

The problem is that the OP wants to put the call into HTML, where it will be in global scope. He can't use the keyword this because this would refer to the global scope (which is window).

action="javascript:this.checkout()" // not as intended
action="javascript:window.checkout()" // same thing

There is no easy way to use an instance member function in HTML. You can do stuff in combination with JavaScript, creating a registry in the static scope of the Class, and then calling a surrogate static method, while passing an argument to that surrogate that gives the index into the registry of your instance, and then having the surrogate call the actual instance member function. Something like this:

// In Javascript:
SimpleCart.registry[1234] = new SimpleCart();

// In HTML
action="javascript:SimpleCart.checkout(1234);"

// In Javascript
SimpleCart.checkout = function(myIndex) {
    var myThis = SimpleCart.registry[myIndex];
    myThis.checkout();
}

You could also store the index as an attribute on the element.

But usually it is easier to just do nothing in HTML and do everything in JavaScript with .addEventListener() and use the .bind() capability.

Using my approach, you can write the button click event handler in the 'classical way', just like how you did it in VB or MFC ;)

Suppose we have a class for a frame window which contains 2 buttons:

class MainWindow {
    Jbutton searchButton;
    Jbutton filterButton;
}

You can use my 'router' class to route the event back to your MainWindow class:

class MainWindow {
    JButton searchButton;
    Jbutton filterButton;
    ButtonClickRouter buttonRouter = new ButtonClickRouter(this);
    
    void initWindowContent() {
        // create your components here...
        
        // setup button listeners
        searchButton.addActionListener(buttonRouter);
        filterButton.addActionListener(buttonRouter);
    }

    void on_searchButton() {
        // TODO your handler goes here...
    }
    
    void on_filterButton() {
        // TODO your handler goes here...
    }
}

Do you like it? :)

If you like this way and hate the Java's anonymous subclass way, then you are as old as I am. The problem of 'addActionListener(new ActionListener {...})' is that it squeezes all button handlers into one outer method which makes the programme look wired. (in case you have a number of buttons in one window)

Finally, the router class is at below. You can copy it into your programme without the need for any update.

Just one thing to mention: the button fields and the event handler methods must be accessible to this router class! To simply put, if you copy this router class in the same package of your programme, your button fields and methods must be package-accessible. Otherwise, they must be public.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public class ButtonClickRouter implements ActionListener {
    private Object target;

    ButtonClickRouter(Object target) {
        this.target = target;
    }

    @Override
    public void actionPerformed(ActionEvent actionEvent) {
        // get source button
        Object sourceButton = actionEvent.getSource();

        // find the corresponding field of the button in the host class
        Field fieldOfSourceButton = null;
        for (Field field : target.getClass().getDeclaredFields()) {
            try {
                if (field.get(target).equals(sourceButton)) {
                    fieldOfSourceButton = field;
                    break;
                }
            } catch (IllegalAccessException e) {
            }
        }

        if (fieldOfSourceButton == null)
            return;

        // make the expected method name for the source button
        // rule: suppose the button field is 'searchButton', then the method
        // is expected to be 'void on_searchButton()'
        String methodName = "on_" + fieldOfSourceButton.getName();

        // find such a method
        Method expectedHanderMethod = null;
        for (Method method : target.getClass().getDeclaredMethods()) {
            if (method.getName().equals(methodName)) {
                expectedHanderMethod = method;
                break;
            }
        }

        if (expectedHanderMethod == null)
            return;

        // fire
        try {
            expectedHanderMethod.invoke(target);
        } catch (IllegalAccessException | InvocationTargetException e) { }
    }
}

            }
        }

        System.out.println("String: " + newStr);
        System.out.println("Int: " + i);
        System.out.println("Double: " + d);

This code works fine

If I understand correctly, you want to know how to convert bytes encoded as a hex string to its form as an ASCII text, like "537461636B" would be converted to "Stack", in such case then the following code should solve your problem.

Have not run any benchmarks but I assume it is not the peak of efficiency.

static char ByteToAscii(const char *input) {
  char singleChar, out;
  memcpy(&singleChar, input, 2);
  sprintf(&out, "%c", (int)strtol(&singleChar, NULL, 16));
  return out;
}

int HexStringToAscii(const char *input, unsigned int length,
                            char **output) {
  int mIndex, sIndex = 0;
  char buffer[length];
  for (mIndex = 0; mIndex < length; mIndex++) {
    sIndex = mIndex * 2;
    char b = ByteToAscii(&input[sIndex]);
    memcpy(&buffer[mIndex], &b, 1);
  }
  *output = strdup(buffer);
  return 0;
}

I hate foo and bar .. who dreamed up these non descriptive terms in programming anyway?

my $oldstring = "replace donotreplace replace donotreplace replace donotreplace";

my $newstring = $oldstring;
$newstring =~ s/replace/newword/g; # inplace replacement

print $newstring;
%: newword donotreplace newword donotreplace newword donotreplace

Use the correct doc type; it will solve the problem. Add the below line to the top of your HTML file:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

The best way for you to do this is to add a proper property that is non-enumerable using Object.defineProperty.

This way you will still be able to iterate over your objects properties without having the newly created "extend" that you would get if you were to create the property with Object.prototype.extend.

Hopefully this helps:

Object.defineProperty(Object.prototype, "extend", {
    enumerable: false,
    value: function(from) {
        var props = Object.getOwnPropertyNames(from);
        var dest = this;
        props.forEach(function(name) {
            if (name in dest) {
                var destination = Object.getOwnPropertyDescriptor(from, name);
                Object.defineProperty(dest, name, destination);
            }
        });
        return this;
    }
});

Once you have that working, you can do:

var obj = {
    name: 'stack',
    finish: 'overflow'
}
var replacement = {
    name: 'stock'
};

obj.extend(replacement);

I just wrote a blog post about it here: http://onemoredigit.com/post/1527191998/extending-objects-in-node-js
