There is now an import functionality on Android ICS 4.0.4.

First you must save your .vcf file on a storage (USB storage, or SDcard). Android will scan the selected storage to detect any .vcf file and will import it on the selected address book. The functionality is in the option menu of your contact list.

!Note: Be careful while doing this! Android will import EVERYTHING that is a .vcf in your storage. It's all or nothing, and the consequence can be trashing your address book.

Post.find().sort({date:-1}, function(err, posts){
});

Should work as well

EDIT:

You can also try using this if you get the error sort() only takes 1 Argument :

Post.find({}, {
    '_id': 0,    // select keys to return here
}, {sort: '-date'}, function(err, posts) {
    // use it here
});

An INNER JOIN can return data from the columns from both tables, and can duplicate values of records on either side have more than one match. A LEFT SEMI JOIN can only return columns from the left-hand table, and yields one of each record from the left-hand table where there is one or more matches in the right-hand table (regardless of the number of matches). It's equivalent to (in standard SQL):

SELECT name
FROM table_1 a
WHERE EXISTS(
    SELECT * FROM table_2 b WHERE (a.name=b.name))

If there are multiple matching rows in the right-hand column, an INNER JOIN will return one row for each match on the right table, while a LEFT SEMI JOIN only returns the rows from the left table, regardless of the number of matching rows on the right side. That's why you're seeing a different number of rows in your result.

I am trying to get the names within table_1 that only appear in table_2.

Then a LEFT SEMI JOIN is the appropriate query to use.

The syntax is:

=GOOGLEFINANCE(ticker, [attribute], [start_date], [num_days|end_date], [interval])

Sample usage:

=GOOGLEFINANCE("GOOG", "price", DATE(2014,1,1), DATE(2014,12,31), "DAILY")
=GOOGLEFINANCE("GOOG","price",TODAY()-30,TODAY())
=GOOGLEFINANCE(A2,A3)
=117.80*Index(GOOGLEFINANCE("CURRENCY:EURGBP", "close", DATE(2014,1,1)), 2, 2)

For instance if you'd like to convert the rate on specific date, here is some more advanced example:

=IF($C2 = "GBP", "", Index(GoogleFinance(CONCATENATE("CURRENCY:", C2, "GBP"), "close", DATE(year($A2), month($A2), day($A2)), DATE(year($A2), month($A2), day($A2)+1), "DAILY"), 2))

where $A2 is your date (e.g. 01/01/2015) and C2 is your currency (e.g. EUR).

See more samples at Docs editors Help at Google.

It's because the name column on the bar table does not have the UNIQUE constraint.

So imagine you have 2 rows on the bar table that contain the name 'ams' and you insert a row on baz with 'ams' on bar_fk, which row on bar would it be referring since there are two rows matching?

a for loop is a construct that says "perform this operation n. times".

a foreach loop is a construct that says "perform this operation against each value/object in this IEnumerable"

If you ensure that every place holder, in each of the contexts involved, is ignoring unresolvable keys then both of these approaches work. For example:

<context:property-placeholder
location="classpath:dao.properties,
          classpath:services.properties,
          classpath:user.properties"
ignore-unresolvable="true"/>

or

    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:dao.properties</value>
                <value>classpath:services.properties</value>
                <value>classpath:user.properties</value>
            </list>
        </property> 
        <property name="ignoreUnresolvablePlaceholders" value="true"/>
    </bean>

If your array is static or global it's initialized to zero before main() starts. That would be the most efficient option.

Well any Javascript object functions sort-of like a "map"

randomObject['hello'] = 'world';

Typically people build simple objects for the purpose:

var myMap = {};

// ...

myMap[newKey] = newValue;

edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do.

13 Feb 2014 — modern JavaScript has facilities for creating object properties that aren't enumerable, and it's pretty easy to do. However, it's still the case that a "put" property, enumerable or not, would claim the property name "put" and make it unavailable. That is, there's still only one namespace per object.

This worked for me:

1. Open control panel
2. click System
3. Then go to Change Environment Variables
4. Then click create a new environment variables
5. Create a new variable named ANDROID_HOME path C:\Android\sdk

Use This Within button on Click option or your needs:

final ProgressDialog progressDialog;
progressDialog = new ProgressDialog(getApplicationContext());
progressDialog.setMessage("Loading..."); // Setting Message
progressDialog.setTitle("ProgressDialog"); // Setting Title
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); // Progress Dialog Style Spinner
progressDialog.show(); // Display Progress Dialog
progressDialog.setCancelable(false);
new Thread(new Runnable() {
    public void run() {
        try {
            Thread.sleep(5000);
        } catch (Exception e) {
            e.printStackTrace();
        }
        progressDialog.dismiss();
    }
}).start();

Just run ADB and use the following command:

adb shell pm uninstall -k --user 0 <package name>

And you should get this return:

successful

In my case, the website just can use TLSv1.2. and i use apache httpclient 4.5.6, i use this code and install jce to solve this (JDK1.7):

jce

jdk7 http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

jdk 8 http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

code:

SSLContext sslContext = SSLContext.getDefault();

  SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(
      sslContext,
      new String[]{"TLSv1.2"}, // important
      null,
      NoopHostnameVerifier.INSTANCE);

  Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
      .register("https", sslConnectionFactory)
      .register("http", PlainConnectionSocketFactory.INSTANCE)
      .build();

  HttpClientConnectionManager ccm = new BasicHttpClientConnectionManager(registry);
  httpclient = HttpClientBuilder.create().
      .setSSLSocketFactory(sslConnectionFactory)
      .setConnectionManager(ccm)
      .build();

Correct ways in jQuery are -

• $('#test').prop('scrollHeight') OR
• $('#test')[0].scrollHeight OR
• $('#test').get(0).scrollHeight

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

Ajax.BeginForm looks to be a fail.

Using a regular Html.Begin for, this does the trick just nicely:

$('#detailsform').submit(function(e) {
    e.preventDefault();
    $.post($(this).attr("action"), $(this).serialize(), function(r) {
        $("#edit").html(r);
    });
}); 

Reflection allows instantiation of new objects, invocation of methods, and get/set operations on class variables dynamically at run time without having prior knowledge of its implementation.

Class myObjectClass = MyObject.class;
Method[] method = myObjectClass.getMethods();

//Here the method takes a string parameter if there is no param, put null.
Method method = aClass.getMethod("method_name", String.class); 

Object returnValue = method.invoke(null, "parameter-value1");

In above example the null parameter is the object you want to invoke the method on. If the method is static you supply null. If the method is not static, then while invoking you need to supply a valid MyObject instance instead of null.

Reflection also allows you to access private member/methods of a class:

public class A{

  private String str= null;

  public A(String str) {
  this.str= str;
  }
}

.

A obj= new A("Some value");

Field privateStringField = A.class.getDeclaredField("privateString");

//Turn off access check for this field
privateStringField.setAccessible(true);

String fieldValue = (String) privateStringField.get(obj);
System.out.println("fieldValue = " + fieldValue);

• For inspection of classes (also know as introspection) you don't need to import the reflection package (java.lang.reflect). Class metadata can be accessed through java.lang.Class.

Reflection is a very powerful API but it may slow down the application if used in excess, as it resolves all the types at runtime.

777 is a permission in Unix based system with full read/write/execute permission to owner, group and everyone.. in general we give this permission to assets which are not much needed to be hidden from public on a web server, for example images..

You said I am using windows 7. if that means that your web server is Windows based then you should login to that and right click the folder and set permissions to everyone and if you are on a windows client and server is unix/linux based then use some ftp software and in the parent directory right click and change the permission for the folder.

If you want permission to be set on sub-directories too then usually their is option to set permission recursively use that.

And, if you feel like doing it from command line the use putty and login to server and go to the parent directory includes and write the following command

chmod 0777 module_installation/

for recursive

chmod -R 0777 module_installation/

Hope this will help you

I see in your Update 2 that you have use sAutoWidth, but I think you mistyped bAutoWidth. Try to change this.

You can also add a CSS rule to .table if the problem persists.

You should also be careful when the width of the content is greater than the header of the column.

So something like the combination of the 1 & 2:

$('.table').dataTable({
  bAutoWidth: false, 
  aoColumns : [
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '15%' },
    { sWidth: '10%' }
  ]
});

You can initialize an array by writing actual values it holds in curly braces on the right hand side like:

String[] strArr = { "one", "two", "three"};
int[] numArr = { 1, 2, 3};

In the same manner two-dimensional array or array-of-arrays holds an array as a value, so:

String strArrayOfArrays = { {"a", "b", "c"}, {"one", "two", "three"} };

Your example shows exactly that

double m[][] = {
    {0*0,1*0,2*0,3*0},
    {0*1,1*1,2*1,3*1},
    {0*2,1*2,2*2,3*2},
    {0*3,1*3,2*3,3*3}
};

But also the multiplication of number will also be performed and its the same as:

double m[][] = { {0, 0, 0, 0}, {0, 1, 2, 3}, {0, 2, 4, 6}, {0, 3, 6, 9} };

I know it's an old thread, but I'd like to point the possible version issue of DotNetCompilerPlatform.dll, f. ex. after an update. Please check, if the new generated Web.config file is different as your released web.config, in particular the system.codedom part. In my case it was the version change from 1.0.7 to 1.0.8. The new dll had been already copied to the server, but I didn't change the old web.config (with some server special settings):

<pre>
  <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.8.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:default /nowarn:1659;1699;1701" />
      <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.8.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:default /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
    </compilers>
  </system.codedom>
</pre>

After I update the two lines, the error disappeared.

This is the best answer for the way I think, but it would have been nicer in a table:

Why is \r a newline for Vim?

So, rewording:

You need to use \r to use a line feed (ASCII 0x0A, the Unix newline) in a regex replacement, but that is peculiar to the replacement - you should normally continue to expect to use \n for line feed and \r for carriage return.

This is because Vim used \n in a replacement to mean the NIL character (ASCII 0x00). You might have expected NIL to have been \0 instead, freeing \n for its usual use for line feed, but \0 already has a meaning in regex replacements, so it was shifted to \n. Hence then going further to also shift the newline from \n to \r (which in a regex pattern is the carriage return character, ASCII 0x0D).

Character                | ASCII code | C representation | Regex match | Regex replacement
-------------------------+------------+------------------+-------------+------------------------
nil                      | 0x00       | \0               | \0          | \n
line feed (Unix newline) | 0x0a       | \n               | \n          | \r
carriage return          | 0x0d       | \r               | \r          | <unknown>

NB: ^M (Ctrl + V Ctrl + M on Linux) inserts a newline when used in a regex replacement rather than a carriage return as others have advised (I just tried it).

Also note that Vim will translate the line feed character when it saves to file based on its file format settings and that might confuse matters.

Maybe too late, but I'd cast 0/1 as bit to make the datatype eventually becomes True/False when consumed by .NET framework:

SELECT   EntityId, 
         EntityName, 
         CASE 
            WHEN EntityProfileIs IS NULL 
            THEN CAST(0 as bit) 
            ELSE CAST(1 as bit) END AS HasProfile
FROM      Entities
LEFT JOIN EntityProfiles ON EntityProfiles.EntityId = Entities.EntityId`

I know this is an old question. The way I solved it - after failing by increasing the length or even changing to data type text - was creating an XLSX file and importing. It accurately detected the data type instead of setting all columns as varchar(50). Turns out nvarchar(255) for that column would have done it too.

For some reason, neither %autoreload, nor dreload seem to work for the situation when you import code from one notebook to another. Only plain Python reload works:

reload(module)

Based on [1].

setCustomValidity's purpose is not just to set the validation message, it itself marks the field as invalid. It allows you to write custom validation checks which aren't natively supported.

You have two possible ways to set a custom message, an easy one that does not involve Javascript and one that does.

The easiest way is to simply use the title attribute on the input element - its content is displayed together with the standard browser message.

<input type="text" required title="Lütfen isaretli yerleri doldurunuz" />

If you want only your custom message to be displayed, a bit of Javascript is required. I have provided both examples for you in this fiddle.

An alternative to AtomicInteger is to use an array (or any other object able to store a value):

final int ordinal[] = new int[] { 0 };
list.forEach ( s -> s.setOrdinal ( ordinal[ 0 ]++ ) );

But see the Stuart's answer: there might be a better way to deal with your case.

On Excel 2010 try this:

1. select the cell you want to check if is used somewhere in a formula;
2. Formulas -> Trace Dependents (on Formula Auditing menu)

Here's a way with gsub:

cs <- c("foo_bar","bar_foo","apple","beer")
gsub('.{3}$', '', cs)
# [1] "foo_" "bar_" "ap"   "b"

If you want to get a class name from inside a class method, class.name or self.class.name won't work. These will just output Class, since the class of a class is Class. Instead, you can just use name:

module Foo
  class Bar
    def self.say_name
      puts "I'm a #{name}!"
    end
  end
end

Foo::Bar.say_name

output:

I'm a Foo::Bar!

Try this code its working Firefox, Chrome, IE

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
<option value="" selected>---Select---</option>
<option value="https://www.google.com">Google</option>
<option value="https://www.google.com">Google</option>
<option value="https://www.google.com">Google</option>
<option value="https://www.google.com">Google</option>

You should use the csv module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows([row[2:4] for _ in range(count)])

or, using the itertools module to do the repeating with itertools.repeat():

from itertools import repeat
import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows(repeat(row[2:4], count))

I ended on this:

function sort_array_of_array(&$array, $subfield)
{
    $sortarray = array();
    foreach ($array as $key => $row)
    {
        $sortarray[$key] = $row[$subfield];
    }

    array_multisort($sortarray, SORT_ASC, $array);
}

Just call the function, passing the array and the name of the field of the second level array. Like:

sort_array_of_array($inventory, 'price');

If order is preserved between files you might also prefer difflib. Although Rob?'s result is the bona-fide standard for intersections you might actually be looking for a rough diff-like:

from difflib import Differ

with open('cfg1.txt') as f1, open('cfg2.txt') as f2:
    differ = Differ()

    for line in differ.compare(f1.readlines(), f2.readlines()):
        if line.startswith(" "):
            print(line[2:], end="")

That said, this has a different behaviour to what you asked for (order is important) even though in this instance the same output is produced.

I think this will handle it better:

my_dict = {0: "c", 1: "d", 2: "e", 3: "f"}

def validate(x, y, z):
    for ele in [x, y, z]:
        if ele in my_dict.keys():
            return my_dict[ele]

Output:

print validate(0, 8, 9)
c
print validate(9, 8, 9)
None
print validate(9, 8, 2)
e

I just stumbled on this old post, and while I'm sure user01 has long since found his answer, I found the current answers don't quite work. After playing around for a little bit using info provided by the others, I found a solution that worked in IE, Firefox, and Chrome. In CSS:

html, body {
    height: 100%;
}

html {
    display: table;
    margin: auto;
}

body {
    display: table-cell;
    vertical-align: middle;
}

This is almost identical to abernier's answer, but I found that including width would break the centering, as would omitting the auto margin. I hope anyone else who stumbles on this thread will find my answer helpful.

Note: Omit html, body { height: 100%; } to only center horizontally.

I finally found here how to do it. To fix it, I needed another dependency:

compile("com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.4.0")

By including this dependency, Spring will automatically register a converter for it, as described here. After that, you need to add the following to application.properties:

spring.jackson.serialization.write_dates_as_timestamps=false

This will ensure that a correct converter is used, and dates will be printed in the format of 2016-03-16T13:56:39.492

Annotations are only needed in case you want to change the date format.

Using tail -f output should work.

public class CloseAppActivity extends AppCompatActivity
{
    public static final void closeApp(Activity activity)
    {
        Intent intent = new Intent(activity, CloseAppActivity.class);
        intent.addCategory(Intent.CATEGORY_HOME);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
                IntentCompat.FLAG_ACTIVITY_CLEAR_TASK);
        activity.startActivity(intent);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        finish();
    }
}

and in manifest:

<activity
     android:name=".presenter.activity.CloseAppActivity"
     android:noHistory="true"
     android:clearTaskOnLaunch="true"/>

Then you can call CloseAppActivity.closeApp(fromActivity) and application will be closed.

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

@paweloque For Comparing two Map Objects in java, you can add the keys of a map to list and with those 2 lists you can use the methods retainAll() and removeAll() and add them to another common keys list and different keys list. Using the keys of the common list and different list you can iterate through map, using equals you can compare the maps.

The below code will give output like this: Before {zoo=barbar, foo=barbar} After {zoo=barbar, foo=barbar} Equal: Before- barbar After- barbar Equal: Before- barbar After- barbar

Had a problem in Angular2, I was using the local storage to save something and it would not let me.

Solutions:

I had localStorage.city -> error -> Property 'city' does not exist on type 'Storage'.

How to fix it:

localStorage['city']

(localStorage).city

(localStorage as any).city

I prefer to use a looping variable, as it tends to read a bit nicer than just "while 1:", and no ugly-looking break statement:

finished = False
while not finished:
    ... do something...
    finished = evaluate_end_condition()

.service-small option {
    font-size: 14px;
    padding: 5px;
    background: #5c5c5c;
}

I think it because you used .styled-select in start of the class code.

Check out all their awesome documentation!

Here is where they discuss the Warning Message.

String + Format

Warning: Browser support for parsing strings is inconsistent. Because there is no specification on which formats should be supported, what works in some browsers will not work in other browsers.

For consistent results parsing anything other than ISO 8601 strings, you should use String + Format.

moment("12-25-1995", "MM-DD-YYYY");

String + Formats (multiple formats)

If you have more than one format, check out their String + Formats (with an 's').

If you don't know the exact format of an input string, but know it could be one of many, you can use an array of formats.

moment("12-25-1995", ["MM-DD-YYYY", "YYYY-MM-DD"]);

Please checkout the documentation for anything more specific.

Timezone

Checkout Parsing in Zone, the equivalent documentation for timezones.

The moment.tz constructor takes all the same arguments as the moment constructor, but uses the last argument as a time zone identifier.

var b = moment.tz("May 12th 2014 8PM", "MMM Do YYYY hA", "America/Toronto");

EDIT

//...
var dateFormat = "YYYY-M-D H:m"; //<-------- This part will get rid of the warning.
var aus1_s, aus2_s, aus3_s, aus4_s, aus5_s, aus6_s, aus6_e;
if ($("#custom1 :selected").val() == "AU" ) {
    var region = 'Australia/Sydney';

    aus1_s = moment.tz('2016-9-26 19:30', dateFormat, region);              
    aus2_s = moment.tz('2016-10-2 19:30', dateFormat, region);              
    aus3_s = moment.tz('2016-10-9 19:30', dateFormat, region);                  
    aus4_s = moment.tz('2016-10-16 19:30', dateFormat, region);                 
    aus5_s = moment.tz('2016-10-23 19:30', dateFormat, region);
    aus6_s = moment.tz('2016-10-30 19:30', dateFormat, region);
    aus6_e = moment.tz('2016-11-5 19:30', dateFormat, region);
} else if ($("#custom1 :selected").val() == "NZ" ) {
    var region = 'Pacific/Auckland';

    aus1_s =  moment.tz('2016-9-28 20:30', dateFormat, region);

you can test if have exactly some values, by example:

for(MyBoolean b : MyBoolean.values()) {
    switch(b) {
    case TRUE:
        break;
    case FALSE:
        break;
    default:
        throw new IllegalArgumentException(b.toString());
}

for(String s : new String[]{"TRUE", "FALSE" }) {
    MyBoolean.valueOf(s);
}

If someone removes or adds a value, some of test fails.

This is my solution:

1. Copy&paste $ANDROID_SDK/extras/android/support/v7/appcompat to your project ROOT

2. Open "Project Structure" on Intellij, click "Modules" on "Project Settings", then click "appcompat"->"android', make sure "Library Module" checkbox is checked.

3. click "YOUR-PROJECT_NAME" under "appcompat", remove "android-support-v4" and "android-support-v7-compat"; ensure the checkbox before "appcompat" is checked. And, click "ok" to close "Project Structure" dialogue.

4. back to the mainwindow, click "appcompat"->"libs" on the top-left project area. Right-click on "android-support-v4", select menuitem "Add as library", change "Add to Module" to "Your-project". Same with "android-support-v7-compat".

After doing above, intellij should be able to correctly find the android-support-XXXX modules.

Good Luck!

string literals are non-modifiable in C

On Mac OS X, I have used BBEdit since the early 1990's, so I use that as my reference for all other editors. I sometimes use BBEdit to edit files on a Linux box using ftp mode, and that works very well if you have a fast network connection to the Linux box.

I learned emacs two years ago because the rest of the programming team I joined uses it. I find emacs powerful but annoyingly old-fashioned in many ways, but once you have learned emacs, you can use it on any platform (Linux, OS X, Windows). This is the editor I use almost exclusively at work now. It is going to take me years to master all its features, though.

I have also used gedit on Linux and found it very usable, but I haven't tried to use it as my primary editor for any project.

I have a colleague at work who uses Komodo Edit 4.4 (free from activestate.com), running it on a Windows computer but using it in ftp mode so she can edit files on our Linux server. Komodo Edit has many nice features, but it takes a looonnnggg time to launch the first time.

If you want to edit some complex javascript I suggest you use JsFiddle. Alternatively, for smaller pieces of javascript you can just run it through your browser URL bar, here's an example:

javascript:alert("hello world");

And, as it was already suggested both Firebug and Chrome developer tools have Javascript console, in which you can type in your javascript to execute. So do Internet Explorer 8+, Opera, Safari and potentially other modern browsers.

You can do

my_set = set(my_list)

or, in Python 3,

my_set = {*my_list}

to create a set from a list. Conversely, you can also do

my_list = list(my_set)

or, in Python 3,

my_list = [*my_set]

to create a list from a set.

Just note that the order of the elements in a list is generally lost when converting the list to a set since a set is inherently unordered. (One exception in CPython, though, seems to be if the list consists only of non-negative integers, but I assume this is a consequence of the implementation of sets in CPython and that this behavior can vary between different Python implementations.)

If you are in Mac OS, you need to open the /usr/local/etc/rabbitmq/rabbitmq-env.conf and set NODE_IP_ADDRESS=, it used to be 127.0.0.1. Then add another user as the accepted answer suggested. After that, restart rabbitMQ, brew services restart rabbitmq

As complement to Mark's answer, the compile function does not have access to scope, but the link function does.

I really recommend this video; Writing Directives by Misko Hevery (the father of AngularJS), where he describes differences and some techniques. (Difference between compile function and link function at 14:41 mark in the video).

// Parent layout
LinearLayout parentLayout = (LinearLayout)findViewById(R.id.layout);

// Layout inflater
LayoutInflater layoutInflater = getLayoutInflater();
View view;

for (int i = 1; i < 101; i++){
    // Add the text layout to the parent layout
    view = layoutInflater.inflate(R.layout.text_layout, parentLayout, false);

    // In order to get the view we have to use the new view with text_layout in it
    TextView textView = (TextView)view.findViewById(R.id.text);
    textView.setText("Row " + i);

    // Add the text view to the parent layout
    parentLayout.addView(textView);
}

I realize that this is an old question, but here's a plugin to address this issue that someone might find useful.

https://github.com/madbook/jquery.wait

lets you do this:

$('#myElement').addClass('load').wait(5000).addClass('done');

The reason why you should use .wait instead of .delay is because not all jquery functions are supported by .delay and that .delay only works with animation functions. For example delay does not support .addClass and .removeClass

Or you can use this function instead.

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

sleep(5000);

t = datetime.strptime('Jul 9, 2009 @ 20:02:58 UTC',"%b %d, %Y @ %H:%M:%S %Z")

Use [[:digit:]] (note the double brackets) as the pattern:

$ hello=ho02123ware38384you443d34o3434ingtod38384day
$ echo ${hello//[[:digit:]]/}
howareyoudoingtodday

Just wanted to summarize the answers (especially @nickl-'s https://stackoverflow.com/a/22261334/2916086).

My two suggestions:

1. Chrome's Postman plugin + the Postman Interceptor Plugin. More Info: Postman Capturing Requests Docs

2. If you're on Windows then Telerik's Fiddler is an option. It has a composer option to replay http requests, and it's free.

It seems you now do not need to reverse geocode and now get the address directly from ClientLocation:

google.loader.ClientLocation.address.city

For something quick:

//$db = new PDO(...);
//$ids = array(...);

$qMarks = str_repeat('?,', count($ids) - 1) . '?';
$sth = $db->prepare("SELECT * FROM myTable WHERE id IN ($qMarks)");
$sth->execute($ids);

You actually can use an inet function. Observe.

main.c:

#include <arpa/inet.h>

main() {
    uint32_t ip = 2110443574;
    struct in_addr ip_addr;
    ip_addr.s_addr = ip;
    printf("The IP address is %s\n", inet_ntoa(ip_addr));
}

The results of gcc main.c -ansi; ./a.out is

The IP address is 54.208.202.125

Note that a commenter said this does not work on Windows.

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

Everything in Java is passed by value .

In the case of the array the reference is copied into a new reference, but remember that everything in Java is passed by value .

Take a look at this interesting article for further information ...

In Java, single quotes can only take one character, with escape if necessary. You need to use full quotation marks as follows for strings:

y = "hello";

You also used

System.out.println(g);

which I assume should be

System.out.println(y);

Note: When making char values (you'll likely use them later) you need single quotes. For example:

char foo='m';

using (StreamWriter writer = new StreamWriter(File.Open(@"E:\Sample.txt", FileMode.Append), Encoding.GetEncoding(1250)))  ////File.Create(path)
        {
            writer.Write("Sample Text");
        }

Parameter Options FollowSymLinks enables you to have a symlink in your webroot pointing to some other file/dir. With this disabled, Apache will refuse to follow such symlink. More secure Options SymLinksIfOwnerMatch can be used instead - this will allow you to link only to other files which you do own.

If you use Options directive in .htaccess with parameter which has been forbidden in main Apache config, server will return HTTP 500 error code.

Allowed .htaccess options are defined by directive AllowOverride in the main Apache config file. To allow symlinks, this directive need to be set to All or Options.

Besides allowing use of symlinks, this directive is also needed to enable mod_rewrite in .htaccess context. But for this, also the more secure SymLinksIfOwnerMatch option can be used.

Here is something:

char const hex_chars[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };

for( int i = data; i < data_length; ++i )
{
    char const byte = data[i];

    string += hex_chars[ ( byte & 0xF0 ) >> 4 ];
    string += hex_chars[ ( byte & 0x0F ) >> 0 ];
}

I came to this topic looking for something similar, but a bit different from the problem posed by lolo. I wanted to construct an HTML page holding an alphabetical menu of links to other pages, and each of the other pages might or might not exist, and the order in which they were created might not be alphabetical (nor even numerical). Also, like Tafkadasoh, I did not want to bloat the web page with jQuery. After researching the problem and experimenting for several hours, here is what worked for me, with relevant remarks added:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

  <title>Menu</title>

<script type="text/javascript">
<!--
var F000, F001, F002, F003, F004, F005, F006, F007, F008, F009,
    F010, F011, F012, F013, F014, F015, F016, F017, F018, F019;
var dat = new Array();
var form, script, write, str, tmp, dtno, indx, unde;

/*
The "F000" and similar variables need to exist/be-declared.
Each one will be associated with a different menu item,
so decide on how many items maximum you are likely to need,
when constructing that listing of them.  Here, there are 20.
*/


function initialize()
{ window.name="Menu";
  form = document.getElementById('MENU');
  for(indx=0; indx<20; indx++)
  { str = "00" + indx;
    tmp = str.length - 3;
    str = str.substr(tmp);
    script = document.createElement('script');
    script.type = 'text/javascript';
    script.src = str + ".js";
    form.appendChild(script);
  }

/*
The for() loop constructs some <script> objects
and associates each one with a different simple file name,
starting with "000.js" and, here, going up to "019.js".
It won't matter which of those files exist or not.
However, for each menu item you want to display on this
page, you will need to ensure that its .js file does exist.

The short function below (inside HTML comment-block) is,
generically, what the content of each one of the .js files looks like:
<!--
function F000()
{ return ["Menu Item Name", "./URLofFile.htm", "Description string"];
}
-->

(Continuing the remarks in the main menu.htm file)
It happens that each call of the form.appendChild() function
will cause the specified .js script-file to be loaded at that time.
However, it takes a bit of time for the JavaScript in the file
to be fully integrated into the web page, so one thing that I tried,
but it didn't work, was to write an "onload" event handler.
The handler was apparently being called before the just-loaded
JavaScript had actually become accessible.

Note that the name of the function in the .js file is the same as one
of the pre-defined variables like "F000".  When I tried to access
that function without declaring the variable, attempting to use an
"onload" event handler, the JavaScript debugger claimed that the item
was "not available".  This is not something that can be tested-for!
However, "undefined" IS something that CAN be tested-for.  Simply
declaring them to exist automatically makes all of them "undefined".
When the system finishes integrating a just-loaded .js script file,
the appropriate variable, like "F000", will become something other
than "undefined".  Thus it doesn't matter which .js files exist or
not, because we can simply test all the "F000"-type variables, and
ignore the ones that are "undefined".  More on that later.

The line below specifies a delay of 2 seconds, before any attempt
is made to access the scripts that were loaded.  That DOES give the
system enough time to fully integrate them into the web page.
(If you have a really long list of menu items, or expect the page
to be loaded by an old/slow computer, a longer delay may be needed.)
*/

  window.setTimeout("BuildMenu();", 2000);
  return;
}


//So here is the function that gets called after the 2-second delay  
function BuildMenu()
{ dtno = 0;    //index-counter for the "dat" array
  for(indx=0; indx<20; indx++)
  { str = "00" + indx;
    tmp = str.length - 3;
    str = "F" + str.substr(tmp);
    tmp = eval(str);
    if(tmp != unde) // "unde" is deliberately undefined, for this test
      dat[dtno++] = eval(str + "()");
  }

/*
The loop above simply tests each one of the "F000"-type variables, to
see if it is "undefined" or not.  Any actually-defined variable holds
a short function (from the ".js" script-file as previously indicated).
We call the function to get some data for one menu item, and put that
data into an array named "dat".

Below, the array is sorted alphabetically (the default), and the
"dtno" variable lets us know exactly how many menu items we will
be working with.  The loop that follows creates some "<span>" tags,
and the the "innerHTML" property of each one is set to become an
"anchor" or "<a>" tag, for a link to some other web page.  A description
and a "<br />" tag gets included for each link.  Finally, each new
<span> object is appended to the menu-page's "form" object, and thereby
ends up being inserted into the middle of the overall text on the page.
(For finer control of where you want to put text in a page, consider
placing something like this in the web page at an appropriate place,
as preparation:
<div id="InsertHere"></div>
You could then use document.getElementById("InsertHere") to get it into
a variable, for appending of <span> elements, the way a variable named
"form" was used in this example menu page.

Note: You don't have to specify the link in the same way I did
(the type of link specified here only works if JavaScript is enabled).
You are free to use the more-standard "<a>" tag with the "href"
property defined, if you wish.  But whichever way you go,
you need to make sure that any pages being linked actually exist!
*/

  dat.sort();
  for(indx=0; indx<dtno; indx++)

If you want to search deleted record (Soft Deleted Record), do't user Eloquent Model Query. Instead use Db::table query e.g Instead of using Below:

$stu = Student::where('rollNum', '=', $rollNum . '-' . $nursery)->first();

Use:

$stu = DB::table('students')->where('rollNum', '=', $newRollNo)->first();

To answer your first question: yes, if the file is not there Python will create it.

Secondly, the user (yourself) running the python script doesn't have write privileges to create a file in the directory.

And now a keys iterator for range-based for loop.

template<typename C>
class keys_it
{
    typename C::const_iterator it_;
public:
    using key_type        = typename C::key_type;
    using pointer         = typename C::key_type*;
    using difference_type = std::ptrdiff_t;

    keys_it(const typename C::const_iterator & it) : it_(it) {}

    keys_it         operator++(int               ) /* postfix */ { return it_++         ; }
    keys_it&        operator++(                  ) /*  prefix */ { ++it_; return *this  ; }
    const key_type& operator* (                  ) const         { return it_->first    ; }
    const key_type& operator->(                  ) const         { return it_->first    ; }
    keys_it         operator+ (difference_type v ) const         { return it_ + v       ; }
    bool            operator==(const keys_it& rhs) const         { return it_ == rhs.it_; }
    bool            operator!=(const keys_it& rhs) const         { return it_ != rhs.it_; }
};

template<typename C>
class keys_impl
{
    const C & c;
public:
    keys_impl(const C & container) : c(container) {}
    const keys_it<C> begin() const { return keys_it<C>(std::begin(c)); }
    const keys_it<C> end  () const { return keys_it<C>(std::end  (c)); }
};

template<typename C>
keys_impl<C> keys(const C & container) { return keys_impl<C>(container); }

Usage:

std::map<std::string,int> my_map;
// fill my_map
for (const std::string & k : keys(my_map))
{
    // do things
}

That's what i was looking for. But nobody had it, it seems.

You get my OCD code alignment as a bonus.

As an exercise, write your own for values(my_map)

start "" AcroRd32.exe /A "page=207" "C:\Users\abc\Desktop\abc xyz def\abc def xyz 2015.pdf"

You may try this, I did it finally, it works!

The way I use these operators:

||, && are for boolean logic. or, and are for control flow. E.g.

do_smth if may_be || may_be -- we evaluate the condition here

do_smth or do_smth_else -- we define the workflow, which is equivalent to do_smth_else unless do_smth

to give a simple example:

> puts "a" && "b"
b

> puts 'a' and 'b'
a

A well-known idiom in Rails is render and return. It's a shortcut for saying return if render, while render && return won't work. See "Avoiding Double Render Errors" in the Rails documentation for more information.

You can use this;

QString data;
data.toStdString().c_str();

FWIW, htpasswd -n username will output the result directly to stdout, and avoid touching files altogether.

Check out TTTAttributedLabel. It's a drop-in replacement for UILabel that allows you to have mixed font and colors in a single label by setting an NSAttributedString as the text for that label.

Here is a component that incorporates much of this by lovasoa: https://github.com/lovasoa/react-contenteditable/blob/master/index.js

He shims the event in the emitChange

emitChange: function(evt){
    var html = this.getDOMNode().innerHTML;
    if (this.props.onChange && html !== this.lastHtml) {
        evt.target = { value: html };
        this.props.onChange(evt);
    }
    this.lastHtml = html;
}

You need to define the button text and have valid HTML for the button. I would also suggest using .on for the click handler of the button

$(function () {_x000D_
  $('#Add').on('click', function () {_x000D_
    $('<p>Text</p>').appendTo('#Content');_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div id="Content">_x000D_
    <button id="Add">Add Text</button>_x000D_
</div>

Also I would make sure the jquery is at the bottom of the page just before the closing </body> tag. Doing so will make it so you do not have to have the whole thing wrapped in $(function but I would still do that. Having your javascript load at the end of the page makes it so the rest of the page loads incase there is a slow down in your javascript somewhere.

I ran into this issue on a simple console app project and my quick solution is to convert any possible datetime2 dates to a nullable datetime by running this method:

static DateTime? ParseDateTime2(DateTime? date)
    {
        if (date == null || date.ToString() == "1/1/0001 12:00:00 AM")
        {
            return null;
        }
        else
        {
            return date;
        }
    }

This is certainly not a completely comprehensive method, but it worked for my needs and maybe it'll help others!

Aside from the ternary operator, you can also use Builder widget if you have operation needs to be performed before the condition statement.

Container(
  child: Builder(builder: (context) {
     /// some operation here ...
     if(someCondition) {
       return Text('A');
     }
     else return Text('B');
    })
 )

parameter?: type is a shorthand for parameter: type | undefined

import java.util.ArrayList;

public class TestClass {

public static void main(String[] args) {

    ArrayList<ArrayList<String>> listOLists = new ArrayList<ArrayList<String>>();
    ArrayList<String> List_1 = new ArrayList<String>();
    List_1.add("1");
    List_1.add("2");
    listOLists.add(List_1);

    ArrayList<String> List_2 = new ArrayList<String>();
    List_2.add("4");
    List_2.add("5");
    List_2.add("10");
    List_2.add("11");
    listOLists.add(List_2);
    for (int i = 0; i < listOLists.size(); i++) {
        System.out.print("list " + i + " :");
        for (int j = 0; j < listOLists.get(i).size(); j++) {
            System.out.print(listOLists.get(i).get(j) + " ;");
        }
        System.out.println();
    }

}

}

I hope this solution gives a better picture of list if lists

You can't. The array doesn't have a name.

You just have two references to the array, one in the variable and another in the third array.

There is no way to find all the references that exist for a given object.

If the name is important, then store it with the data.

var size = { data: ["S", "M", "L", "XL", "XXL"], name: 'size' };
var color = { data: ["Red", "Blue", "Green", "White", "Black"], name: 'color' };
var options = [size, color];

Obviously you'll have to modify the existing code which accesses the data (since you now have options[0].data[0] instead of options[0][0] but you also have options[0].name).

Please note that this works with java.lang.SuppressWarningsso no need to use a separate annotation.

@SuppressWarnings on a field only suppresses findbugs warnings reported for that field declaration, not every warning associated with that field.

For example, this suppresses the "Field only ever set to null" warning:

@SuppressWarnings("UWF_NULL_FIELD") String s = null; I think the best you can do is isolate the code with the warning into the smallest method you can, then suppress the warning on the whole method.

In my case it was simply that I had a variable named the same as a function.

Example:

def cleanCache = functionReturningABoolean()

if( cleanCache ){
    echo "Clean cache option is true, do not uninstall previous features / urls"
    uninstallCmd = ""
    
    // and we call the cleanCache method
    cleanCache(userId, serverName)
}
...

and later in my code I have the function:

def cleanCache(user, server){

 //some operations to the server

}

Apparently the Groovy language does not support this (but other languages like Java does). I just renamed my function to executeCleanCache and it works perfectly (or you can also rename your variable whatever option you prefer).

My solution, using a SwitchCompat and Kotlin. In my situation, i needed to react to a change only if the user triggered it through the UI. In fact, my switch reacts to a LiveData, and this made both setOnClickListener and setOnCheckedChangeListener unusable. setOnClickListener in fact reacts correctly to user interaction, but it's not triggered if the user drags the thumb across the switch. setOnCheckedChangeListener on the other end is triggered also if the switch is toggled programmatically (for example by an observer). Now in my case the switch was present on two fragments, and so onRestoreInstanceState would trigger in some cases the switch with an old value overwriting the correct value.

So, i looked at the code of SwitchCompat, and was able to mimic it's behaviour successfully in distinguishing click and drag and used that to build a custom touchlistener that works as it should. Here we go:

/**
 * This function calls the lambda function passed with the right value of isChecked
 * when the switch is tapped with single click isChecked is relative to the current position so we pass !isChecked
 * when the switch is dragged instead, the position of the thumb centre where the user leaves the
 * thumb is compared to the middle of the switch, and we assume that left means false, right means true
 * (there is no rtl or vertical switch management)
 * The behaviour is extrapolated from the SwitchCompat source code
 */
class SwitchCompatTouchListener(private val v: SwitchCompat, private val lambda: (Boolean)->Unit) :  View.OnTouchListener {
    companion object {
        private const val TOUCH_MODE_IDLE = 0
        private const val TOUCH_MODE_DOWN = 1
        private const val TOUCH_MODE_DRAGGING = 2
    }

    private val vc = ViewConfiguration.get(v.context)
    private val mScaledTouchSlop = vc.scaledTouchSlop
    private var mTouchMode = 0
    private var mTouchX = 0f
    private var mTouchY = 0f

    /**
     * @return true if (x, y) is within the target area of the switch thumb
     * x,y and rect are in view coordinates, 0,0 is top left of the view
     */
    private fun hitThumb(x: Float, y: Float): Boolean {
        val rect = v.thumbDrawable.bounds
        return x >= rect.left && x <= rect.right && y >= rect.top && y <= rect.bottom
    }

    override fun onTouch(view: View, event: MotionEvent): Boolean {
        if (view == v) {

                MotionEvent.ACTION_DOWN -> {

                    val y = event.y
                    if (v.isEnabled && hitThumb(x, y)) {
                        mTouchMode = TOUCH_MODE_DOWN;
                        mTouchX = x;
                        mTouchY = y;
                    }
                }
                MotionEvent.ACTION_MOVE -> {

                    if (mTouchMode == TOUCH_MODE_DOWN &&
                        (abs(x - mTouchX) > mScaledTouchSlop || abs(y - mTouchY) > mScaledTouchSlop)
                    )
                        mTouchMode = TOUCH_MODE_DRAGGING;
                }
                MotionEvent.ACTION_UP,
                MotionEvent.ACTION_CANCEL -> {
                    if (mTouchMode == TOUCH_MODE_DRAGGING) {
                        val r = v.thumbDrawable.bounds
                        if (r.left + r.right < v.width) lambda(false)
                        else lambda(true)
                    } else lambda(!v.isChecked)
                    mTouchMode = TOUCH_MODE_IDLE;
                }
            }
        }
        return v.onTouchEvent(event)
    }
}

How to use it:

the actual touch listener that accepts a lambda with the code to execute:

myswitch.setOnTouchListener(
    SwitchCompatTouchListener(myswitch) {
        // here goes all the code for your callback, in my case
        // i called a service which, when successful, in turn would 
        // update my liveData 
        viewModel.sendCommandToMyService(it) 
    }
)

For the sake of completeness, this is how the observer for the state switchstate (if you have it) looked like:

switchstate.observe(this, Observer {
    myswitch.isChecked = it
})

a = ['it']
b = ['was']
c = ['annoying']

a.extend(b)
a.extend(c)

# a now equals ['it', 'was', 'annoying']

YAML version :

overrides:
  - files: *-tests.js
    rules:
      no-param-reassign: 0

Example of specific rules for mocha tests :

You can also set a specific env for a folder, like this :

overrides:
  - files: test/*-tests.js
    env:
      mocha: true

This configuration will fix error message about describe and it not defined, only for your test folder:

/myproject/test/init-tests.js
6:1 error 'describe' is not defined no-undef
9:3 error 'it' is not defined no-undef

<uses-sdk tools:node="replace" />

No longer works.

change uses-sdk to

<uses-sdk tools:overrideLibrary="com.packagename.of.libary.with.conflict" />

and add
xmlns:tools="http://schemas.android.com/tools" in the AndroidManifest.xml file

There is not a program but you can make a batch file and run a command like that :

Tested Answer By me:

form.html

<input type="text" (keypress)="restrictNumeric($event)">

form.component.ts:

public restrictNumeric(e) {
  let input;
  if (e.metaKey || e.ctrlKey) {
    return true;
  }
  if (e.which === 32) {
   return false;
  }
  if (e.which === 0) {
   return true;
  }
  if (e.which < 33) {
    return true;
  }
  input = String.fromCharCode(e.which);
  return !!/[\d\s]/.test(input);
 }

Use the date_trunc method to truncate off the day (or whatever else you want, e.g., week, year, day, etc..)

Example of grouping sales from orders by month:

select
  SUM(amount) as sales,
  date_trunc('month', created_at) as date
from orders
group by date
order by date DESC;

Note that connection strings are specific to what and how you are connecting to data. These are connecting to the same database but the first is using .NET Framework Data Provider for SQL Server. Integrated Security=True will not work for OleDb.

• Data Source=.;Initial Catalog=aspnetdb;Integrated Security=True
• Provider=SQLOLEDB;Data Source=.;Integrated Security=SSPI;Initial Catalog=aspnetdb

When in doubt use the Visual Studio Server Explorer Data Connections.

• What is sspi?
• Connection Strings Syntax

To summarize what was mentioned by Breno above

Say you have a variable with a path to a file

path = '/home/User/Desktop/myfile.py'

os.path.basename(path) returns the string 'myfile.py'

and

os.path.dirname(path) returns the string '/home/User/Desktop' (without a trailing slash '/')

These functions are used when you have to get the filename/directory name given a full path name.

In case the file path is just the file name (e.g. instead of path = '/home/User/Desktop/myfile.py' you just have myfile.py), os.path.dirname(path) returns an empty string.

mingw32 exists as a package for Linux. You can cross-compile and -link Windows applications with it. There's a tutorial here at the Code::Blocks forum. Mind that the command changes to x86_64-w64-mingw32-gcc-win32, for example.

Ubuntu, for example, has MinGW in its repositories:

$ apt-cache search mingw
[...]
g++-mingw-w64 - GNU C++ compiler for MinGW-w64
gcc-mingw-w64 - GNU C compiler for MinGW-w64
mingw-w64 - Development environment targeting 32- and 64-bit Windows

On the Admin Panel Dashboard, you can find a box called "Right Now". There you can see the version of the WordPress installation. I have seen this result in WordPress 3.2.1. You can also see this in version 3.7.1

UPDATE:

In WP Version 3.8.3

In WP Version 3.9.1 Admin Side, You can see the version by clicking the WP logo which is located at the left-top position.

You can use yoursitename/readme.html

In the WordPress Admin Footer at the Right side, you will see the version info(Version 3.9.1).

You can get the WordPress version using the following code:

<?php bloginfo('version'); ?>

The below file is having all version details

wp-includes/version.php   

Update for WP 4.1.5

In WP 4.1.5, If it was the latest WP version in the footer right part, it will show the version as it is. If not, it will show the latest WP version with the link to update.

Check the below screenshot.

If I may suggest a safer approach:

Declare a buffer big enough to hold the string:

char user_input[255];

Get the user input in a safe way:

fgets(user_input, 255, stdin);

A safe way to get the input, the first argument being a pointer to a buffer where the input will be stored, the second the maximum input the function should read and the third is a pointer to the standard input - i.e. where the user input comes from.

Safety in particular comes from the second argument limiting how much will be read which prevents buffer overruns. Also, fgets takes care of null-terminating the processed string.

More info on that function here.

EDIT: If you need to do any formatting (e.g. convert a string to a number), you can use atoi once you have the input.

For systemd style init scripts it's really easy. You just add a User= in the [Service] section.

Here is an init script I use for qbittorrent-nox on CentOS 7:

[Unit]
Description=qbittorrent torrent server

[Service]
User=<username>
ExecStart=/usr/bin/qbittorrent-nox
Restart=on-abort

[Install]
WantedBy=multi-user.target

The best method, in my opinion, is to use what's gone before.

There are lists of the first N primes on the internet with N stretching up to at least fifty million. Download the files and use them, it's likely to be much faster than any other method you'll come up with.

If you want an actual algorithm for making your own primes, Wikipedia has all sorts of good stuff on primes here, including links to the various methods for doing it, and prime testing here, both probability-based and fast-deterministic methods.

There should be a concerted effort to find the first billion (or even more) primes and get them published on the net somewhere so people can stop doing this same job over and over and over and ... :-)

Can't find the libpq-fe.h header

i had success on CentOS 7.0.1406 running the following commands:

~ % psql --version # => psql (PostgreSQL) 9.4.1
yum install libpqxx-devel
gem install pg -- --with-pg-config=/usr/pgsql-9.4/bin/pg_config

Alternatively, you can configure bundler to always install pg with these options (helpful for running bundler in deploy environments),

• bundle config build.pg --with-pg-config=/usr/pgsql-9.4/bin/pg_config

The latest version of MAMP (Version 5+) offers an easy way to make the MAMP PHP version available to the command line. Just select "PHP" in the the side bar menu and check "Make this version available on the command line". Easy peasy! See attached screenshot:)

I've been playing around with this, as I love my enums. =)

Using Object.defineProperty I think I came up with a somewhat viable solution.

Here's a jsfiddle: http://jsfiddle.net/ZV4A6/

Using this method.. you should (in theory) be able to call and define enum values for any object, without affecting other attributes of that object.

Object.defineProperty(Object.prototype,'Enum', {
    value: function() {
        for(i in arguments) {
            Object.defineProperty(this,arguments[i], {
                value:parseInt(i),
                writable:false,
                enumerable:true,
                configurable:true
            });
        }
        return this;
    },
    writable:false,
    enumerable:false,
    configurable:false
}); 

Because of the attribute writable:false this should make it type safe.

So you should be able to create a custom object, then call Enum() on it. The values assigned start at 0 and increment per item.

var EnumColors={};
EnumColors.Enum('RED','BLUE','GREEN','YELLOW');
EnumColors.RED;    // == 0
EnumColors.BLUE;   // == 1
EnumColors.GREEN;  // == 2
EnumColors.YELLOW; // == 3

My solution:

#ifdef WIN32
    #include <Windows.h>
    #include <tchar.h>
#else
    #include <unistd.h>
#endif

void GetMachineName(char machineName[150])
{
    char Name[150];
    int i=0;

    #ifdef WIN32
        TCHAR infoBuf[150];
        DWORD bufCharCount = 150;
        memset(Name, 0, 150);
        if( GetComputerName( infoBuf, &bufCharCount ) )
        {
            for(i=0; i<150; i++)
            {
                Name[i] = infoBuf[i];
            }
        }
        else
        {
            strcpy(Name, "Unknown_Host_Name");
        }
    #else
        memset(Name, 0, 150);
        gethostname(Name, 150);
    #endif
    strncpy(machineName,Name, 150);
}

npm --depth 9999 update fixed the issue for me--apparently because package-lock.json was insisting on the outdated versions.

In Excel 2013 and resent versions, you can use F2 and F4 to speed things up when you want to toggle the lock.

About the keys:

• F2 - With a cell selected, it places the cell in formula edit mode.

• F4 - Toggles the cell reference lock (the $ signs).

• Example scenario with 'A4'.

  • Pressing F4 will convert 'A4' into '$A$4'
  • Pressing F4 again converts '$A$4' into 'A$4'
  • Pressing F4 again converts 'A$4' into '$A4'
  • Pressing F4 again converts '$A4' back to the original 'A4'

How To:

• In Excel, select a cell with a formula and hit F2 to enter formula edit mode. You can also perform these next steps directly in the Formula bar. (Issue with F2 ? Double check that 'F Lock' is on)

  • If the formula has one cell reference;
    • Hit F4 as needed and the single cell reference will toggle.
  • If the forumla has more than one cell reference, hitting F4 (without highlighting anything) will toggle the last cell reference in the formula.
  • If the formula has more than one cell reference and you want to change them all;
    • You can use your mouse to highlight the entire formula or you can use the following keyboard shortcuts;
    • Hit End key (If needed. Cursor is at end by default)
    • Hit Ctrl + Shift + Home keys to highlight the entire formula
    • Hit F4 as needed
  • If the formula has more than one cell reference and you only want to edit specific ones;
    • Highlight the specific values with your mouse or keyboard ( Shift and arrow keys) and then hit F4 as needed.

Notes:

• These notes are based on my observations while I was looking into this for one of my own projects.
• It only works on one cell formula at a time.
• Hitting F4 without selecting anything will update the locking on the last cell reference in the formula.
• Hitting F4 when you have mixed locking in the formula will convert everything to the same thing. Example two different cell references like '$A4' and 'A$4' will both become 'A4'. This is nice because it can prevent a lot of second guessing and cleanup.
• Ctrl+A does not work in the formula editor but you can hit the End key and then Ctrl + Shift + Home to highlight the entire formula. Hitting Home and then Ctrl + Shift + End.
• OS and Hardware manufactures have many different keyboard bindings for the Function (F Lock) keys so F2 and F4 may do different things. As an example, some users may have to hold down you 'F Lock' key on some laptops.
• 'DrStrangepork' commented about F4 actually closes Excel which can be true but it depends on what you last selected. Excel changes the behavior of F4 depending on the current state of Excel. If you have the cell selected and are in formula edit mode (F2), F4 will toggle cell reference locking as Alexandre had originally suggested. While playing with this, I've had F4 do at least 5 different things. I view F4 in Excel as an all purpose function key that behaves something like this; "As an Excel user, given my last action, automate or repeat logical next step for me".

Try this, it's working for me.

Sender:

byte[] message = ...
Socket socket = ...
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

dOut.writeInt(message.length); // write length of the message
dOut.write(message);           // write the message

Receiver:

Socket socket = ...
DataInputStream dIn = new DataInputStream(socket.getInputStream());

int length = dIn.readInt();                    // read length of incoming message
if(length>0) {
    byte[] message = new byte[length];
    dIn.readFully(message, 0, message.length); // read the message
}

I just went to the file system and deleted the file directly, then continued with git checkout and it worked.

I've had the problem occur several times and it may be related to developers doing delete, push, re-add, push or some such thing.

No mention of Merge?

DataSet newdataset = new DataSet();

newdataset.Merge( olddataset.Tables[0].Select( filterstring, sortstring ));

What you want to do is called "serialization". There are several ways of doing it, but if you don't need anything fancy I think using the standard Java object serialization would do just fine.

Perhaps you could use something like this?

package com.example;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class Serializer {

    public static byte[] serialize(Object obj) throws IOException {
        try(ByteArrayOutputStream b = new ByteArrayOutputStream()){
            try(ObjectOutputStream o = new ObjectOutputStream(b)){
                o.writeObject(obj);
            }
            return b.toByteArray();
        }
    }

    public static Object deserialize(byte[] bytes) throws IOException, ClassNotFoundException {
        try(ByteArrayInputStream b = new ByteArrayInputStream(bytes)){
            try(ObjectInputStream o = new ObjectInputStream(b)){
                return o.readObject();
            }
        }
    }

}

There are several improvements to this that can be done. Not in the least the fact that you can only read/write one object per byte array, which might or might not be what you want.

Note that "Only objects that support the java.io.Serializable interface can be written to streams" (see java.io.ObjectOutputStream).

Since you might run into it, the continuous allocation and resizing of the java.io.ByteArrayOutputStream might turn out to be quite the bottle neck. Depending on your threading model you might want to consider reusing some of the objects.

For serialization of objects that do not implement the Serializable interface you either need to write your own serializer, for example using the read*/write* methods of java.io.DataOutputStream and the get*/put* methods of java.nio.ByteBuffer perhaps together with reflection, or pull in a third party dependency.

This site has a list and performance comparison of some serialization frameworks. Looking at the APIs it seems Kryo might fit what you need.

I got similar error after deleting a subproject, removed

"*compile project(path: ':MySubProject', configuration: 'android-endpoints')*"

in build.gradle (dependencies) under Gradle Scripts

What I have found is that sometimes the library that the linker complains about is not the one causing the problem. Possibly there is a clever way to work out where the problem is but this is what I do:

• Comment out all the linked libraries in the link command.
• Clean out all .o's, .so's etc (Usually make clean is enough, but you may want to run a recursive find + rm, or something similar).
• Uncomment the libraries in the link command one at a time and re-arrange the order as necessary.

@peter karasev: I have come across the same problem with a gcc 4.8.2 cmake project on CentOS7. The order of the libraries in "target_link_libraries" section is important. I guess cmake just passes the list on to the linker as-is, i.e. it doesn't try and work out the correct order. This is reasonable - when you think about it cmake can't know what the correct order is until the linking is successfully completed.

I feel most people have pip installed already with Python. On Windows, one way to check for pip is to open Command Prompt and typing in:

python -m pip

If you get Usage and Commands instructions then you have it installed. If python was not found though, then it needs to be added to the path. Alternatively you can run the same command from within the installation directory of python.

If all is good, then this command will install BeautifulSoup easily:

python -m pip install BeautifulSoup4

Screenshot:

N' now I see I need to upgrade my pip, which I just did :)

If you mean you want to sort by date first then by names

SELECT id, name, form_id, DATE(updated_at) as date
  FROM wp_frm_items
  WHERE user_id = 11 && form_id=9
  ORDER BY updated_at DESC,name ASC

This will sort the records by date first, then by names

The easiest option is to start a windows forms project, then change the output-type to Console Application. Alternatively, just add a reference to System.Windows.Forms.dll, and start coding:

using System.Windows.Forms;

[STAThread]
static void Main() {
    Application.EnableVisualStyles();
    Application.Run(new Form()); // or whatever
}

The important bit is the [STAThread] on your Main() method, required for full COM support.

The simpler version which I've came across is as following. For education purposes, it is best, because it does not use any abstract libraries.

var http = require('http'),
url = require('url'),
path = require('path'),
fs = require('fs');

var mimeTypes = {
  "html": "text/html",
  "mp3":"audio/mpeg",
  "mp4":"video/mp4",
  "jpeg": "image/jpeg",
  "jpg": "image/jpeg",
  "png": "image/png",
  "js": "text/javascript",
  "css": "text/css"};

http.createServer(function(req, res) {
    var uri = url.parse(req.url).pathname;
    var filename = path.join(process.cwd(), uri);
    fs.exists(filename, function(exists) {
        if(!exists) {
            console.log("not exists: " + filename);
            res.writeHead(200, {'Content-Type': 'text/plain'});
            res.write('404 Not Found\n');
            res.end();
            return;
        }
        var mimeType = mimeTypes[path.extname(filename).split(".")[1]];
        res.writeHead(200, {'Content-Type':mimeType});

        var fileStream = fs.createReadStream(filename);
        fileStream.pipe(res);

    }); //end path.exists
}).listen(1337);

Now go to browser and open following:

http://127.0.0.1/image.jpg

Here image.jpg should be in same directory as this file. Hope this helps someone :)

It took me months of googling to find a solution for this issue. You don't need to install a virtual environment running a 32-bit version of Windows to run a program with a 16-bit installer on 64-bit Windows. If the program itself is 32-bit, and just the installer is 16-bit, here's your answer.

There are ways to modify a 16-bit installation program to make it 32-bit so it will install on 64-bit Windows 7. I found the solution on this site:

http://www.reactos.org/forum/viewtopic.php?f=22&t=10988

In my case, the installation program was InstallShield 5.X. The issue was that the setup.exe program used by InstallShield 5.X is 16-bit. First I extracted the installation program contents (changed the extension from .exe to .zip, opened it and extracted). I then replaced the original 16-bit setup.exe, located in the disk1 folder, with InstallShield's 32-bit version of setup.exe (download this file from the site referenced in the above link). Then I just ran the new 32-bit setup.exe in disk1 to start the installation and my program installed and runs perfectly on 64-bit Windows.

You can also repackage this modified installation, so it can be distributed as an installation program, using a free program like Inno Setup 5.

The ISO 7000 / IEC 60417 Symbol for Pause; Interruption is #5111B. See Media_Controls

private boolean negate(boolean val) {
    return !val;
}

I think that is what you are asking for??

ugh, just to iterate over my own case, which gave out approximately the same error - in the Resource declaration (server.xml) make sure to NOT omit driverClassName, and that e.g. for Oracle it is "oracle.jdbc.OracleDriver", and that the right JAR file (e.g. ojdbc14.jar) exists in %CATALINA_HOME%/lib

check for scipy.stats module:

 scipy.stats.scoreatpercentile

dgg

will delete everything from your current line to the top of the file.

d is the deletion command, and gg is a movement command that says go to the top of the file, so when used together, it means delete from my current position to the top of the file.

Also

dG

will delete all lines at or below the current one

Instead of passing the ID, you can just pass the element itself:

<link onclick="doWithThisElement(this)" />

Or, if you insist on passing the ID:

<link id="foo" onclick="doWithThisElement(this.id)" />

Here's the JSFiddle Demo: http://jsfiddle.net/dRkuv/

You'll find that in javascript, there are usually many different ways to do the same thing or find the same information. In your example, you are looking for some element that is guaranteed to always exist. window and document both fit the bill (with just a few differences).

From mozilla dev network:

addEventListener() registers a single event listener on a single target. The event target may be a single element in a document, the document itself, a window, or an XMLHttpRequest.

So as long as you can count on your "target" always being there, the only difference is what events you're listening for, so just use your favorite.

try

npm install --force
npm install --legacy-peer-deps

Don't look any further:

0 3 * * * /usr/bin/env bash -c 'cd /home/user/project && source /home/user/project/env/bin/activate && ./manage.py command arg' > /dev/null 2>&1

Generic approach:

* * * * * /usr/bin/env bash -c 'YOUR_COMMAND_HERE' > /dev/null 2>&1

The beauty about this is you DO NOT need to change the SHELL variable for crontab from sh to bash

I would recommend following Matt Hamsmith's solution. If it's an issue to implement, then why not create an extension method that implements this in the background on the AppSettings class?

Something like:

    public static string GetValue(this NameValueCollection settings, string key)
    {

    }

Inside the method you search through the DictionaryInfoConfigSection using Linq and return the value with the matching key. You'll need to update the config file though, to something along these lines:

<appSettings>
  <DirectoryMappings>
    <DirectoryMap key="MyBaseDir" value="C:\MyBase" />
    <DirectoryMap key="Dir1" value="[MyBaseDir]\Dir1"/>
    <DirectoryMap key="Dir2" value="[MyBaseDir]\Dir2"/>
  </DirectoryMappings>
</appSettings>

You can see a complete example using java 8, recursion and streams -> Dijkstra algorithm with java

Android Studio takes source version equal to Target Version in your application. Compilation performed with source version equal to above mentioned Compile Version. So, take care that in your project Compile Version == Target Version (adjust module's build.gradle file).

Until fix is not merged into master branch, to get host IP just run from inside of the container:

ip -4 route list match 0/0 | cut -d' ' -f3

(as suggested by @Mahoney here).

As Marc says, you run it exactly like you would from the command line. See Creating SQL Server Agent Jobs on MSDN.

I would like to augment to Stephen C's answer, my case was on the first dot. So since we have DHCP to allocate IP addresses in the company, DHCP changed my machine's address without of course asking neither me nor Oracle. So out of the blue oracle refused to do anything and gave the minus one dreaded exception. So if you want to workaround this once and for ever, and since TCP.INVITED_NODES of SQLNET.ora file does not accept wildcards as stated here, you can add you machine's hostname instead of the IP address.

Exported variables such as $HOME and $PATH are available to (inherited by) other programs run by the shell that exports them (and the programs run by those other programs, and so on) as environment variables. Regular (non-exported) variables are not available to other programs.

$ env | grep '^variable='
$                                 # No environment variable called variable
$ variable=Hello                  # Create local (non-exported) variable with value
$ env | grep '^variable='
$                                 # Still no environment variable called variable
$ export variable                 # Mark variable for export to child processes
$ env | grep '^variable='
variable=Hello
$
$ export other_variable=Goodbye   # create and initialize exported variable
$ env | grep '^other_variable='
other_variable=Goodbye
$

For more information, see the entry for the export builtin in the GNU Bash manual, and also the sections on command execution environment and environment.

Note that non-exported variables will be available to subshells run via ( ... ) and similar notations because those subshells are direct clones of the main shell:

$ othervar=present
$ (echo $othervar; echo $variable; variable=elephant; echo $variable)
present
Hello
elephant
$ echo $variable
Hello
$

The subshell can change its own copy of any variable, exported or not, and may affect the values seen by the processes it runs, but the subshell's changes cannot affect the variable in the parent shell, of course.

Some information about subshells can be found under command grouping and command execution environment in the Bash manual.

Just to answer your question and not to continue any discussions. The Apache Harmony JDK implementation seems to use a different algorithm, at least it looks totally different:

Sun JDK

public int hashCode() {
    int h = hash;
    if (h == 0) {
        int off = offset;
        char val[] = value;
        int len = count;

        for (int i = 0; i < len; i++) {
            h = 31*h + val[off++];
        }
        hash = h;
    }
    return h;
}

Apache Harmony

public int hashCode() {
    if (hashCode == 0) {
        int hash = 0, multiplier = 1;
        for (int i = offset + count - 1; i >= offset; i--) {
            hash += value[i] * multiplier;
            int shifted = multiplier << 5;
            multiplier = shifted - multiplier;
        }
        hashCode = hash;
    }
    return hashCode;
}

This code simulates a click on the burguer button to close the navbar by clicking on a link in the menu, keeping the fade out effect. Solution with typescript for angular 7. Avoid routerLink problems.

ToggleNavBar () {
    let element: HTMLElement = document.getElementsByClassName( 'navbar-toggler' )[ 0 ] as HTMLElement;
    if ( element.getAttribute( 'aria-expanded' ) == 'true' ) {
        element.click();
    }
}

<li class="nav-item" [routerLinkActive]="['active']">
    <a class="nav-link" [routerLink]="['link1']" title="link1" (click)="ToggleNavBar()">link1</a>
</li>

Are you refering to the toggle outlining?

You can do: Control + M then Control + L to toggle all outlining

iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.

If you have issues deleting the topics, try to delete the topic using:

$KAFKA_HOME/bin/kafka-topics.sh --delete --zookeeper localhost:2181 --topic your_topic_name

command. Then in order to verify the deletion process, go to the kafka logs directory which normally is placed under /tmp/kafka-logs/, then delete the your_topic_name file via rm -rf your_topic_name command.

Remember to monitor the whole process via a kafka management tool like Kafka Tool.

The mentioned process above will remove the topics without kafka server restart.

The code which works fine for me is :-

  final int MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE = 102;
  if ((ContextCompat.checkSelfPermission(getActivity(),Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)) {

                requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                        MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE);
            } else {
        // user already provided permission
                // perform function for what you want to achieve
     }

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {

    boolean canUseExternalStorage = false;

    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE: {
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                canUseExternalStorage = true;
            }

            if (!canUseExternalStorage) {
                Toast.makeText(getActivity(), "Cannot use this feature without requested permission", Toast.LENGTH_SHORT).show();
            } else {
                // user now provided permission
                // perform function for what you want to achieve
            }
        }
      }
 }

console.log is only defined when the console is open. If you want to check for it in your code make sure you check for for it within the window property

if (window.console)
    console.log(msg)

this throws an exception in IE9 and will not work correctly. Do not do this

if (console) 
    console.log(msg)

I recommend Logo (aka the turtle) to get the basic concepts down. It provides a good sandbox with immediate graphical feedback, and you can demostrate loops, variables, functions, conditionals, etc. This page provides an excellent tutorial.

After Logo, move to Python or Ruby. I recommend Python, as it's based on ABC, which was invented for the purpose of teaching programming.

When teaching programming, I must second EHaskins's suggestion of simple projects and then complex projects. The best way to learn is to start with a definite outcome and a measurable milestone. It keeps the lessons focused, allows the student to build skills and then build on those skills, and gives the student something to show off to friends. Don't underestimate the power of having something to show for one's work.

Theoretically, you can stick with Python, as Python can do almost anything. It's a good vehicle to teach object-oriented programming and (most) algorithms. You can run Python in interactive mode like a command line to get a feel for how it works, or run whole scripts at once. You can run your scripts interpreted on the fly, or compile them into binaries. There are thousands of modules to extend the functionality. You can make a graphical calculator like the one bundled with Windows, or you can make an IRC client, or anything else.

XKCD describes Python's power a little better:

You can move to C# or Java after that, though they don't offer much that Python doesn't already have. The benefit of these is that they use C-style syntax, which many (dare I say most?) languages use. You don't need to worry about memory management yet, but you can get used to having a bit more freedom and less handholding from the language interpreter. Python enforces whitespace and indenting, which is nice most of the time but not always. C# and Java let you manage your own whitespace while remaining strongly-typed.

From there, the standard is C or C++. The freedom in these languages is almost existential. You are now in charge of your own memory management. There is no garbage collection to help you. This is where you teach the really advanced algorithms (like mergesort and quicksort). This is where you learn why "segmentation fault" is a curse word. This is where you download the source code of the Linux kernel and gaze into the Abyss. Start by writing a circular buffer and a stack for string manipulation. Then work your way up.

Starting from Swift 3.0 you can

var str = String(describing: Audience.friends)

Hope this will help little more :-

var string = "123456789"

If you want a substring after some particular index.

var indexStart  =  string.index(after: string.startIndex )// you can use any index in place of startIndex
var strIndexStart   = String (string[indexStart...])//23456789

If you want a substring after removing some string at the end.

var indexEnd  =  string.index(before: string.endIndex)
var strIndexEnd   = String (string[..<indexEnd])//12345678

you can also create indexes with the following code :-

var  indexWithOffset =  string.index(string.startIndex, offsetBy: 4)

w3wp.exe is a process associated with the application pool in IIS. If you have more than one application pool, you will have more than one instance of w3wp.exe running. This process usually allocates large amounts of resources. It is important for the stable and secure running of your computer and should not be terminated.

You can get more information on w3wp.exe here

http://www.processlibrary.com/en/directory/files/w3wp/25761/

I discovered you can run the installer in Wine. This works:

WINEPREFIX=/home/jason/java wine jre-7u11-windows-i586.exe

Then once it is finished you can just zip up the /home/jason/java/drive_c/Program\ Files\ \(x86\)/Java/jre7/

This should work for jdk as well

It's a ternary operator, or the short form for if..else.

condition ? value if true : value if false

See Microsoft Docs | ?: operator (C# reference).

Your '/0' should be '\0' .. you got the slash reversed/leaning the wrong way. Your while should look like:

while (*(forward++)!='\0') 

though the != '\0' part of your expression is optional here since the loop will continue as long as it evaluates to non-zero (null is considered zero and will terminate the loop).

All "special" characters (i.e., escape sequences for non-printable characters) use a backward slash, such as tab '\t', or newline '\n', and the same for null '\0' so it's easy to remember.

Parsing and code generation are actually rather fast. The real problem is opening and closing files. Remember, even with include guards, the compiler still have open the .H file, and read each line (and then ignore it).

A friend once (while bored at work), took his company's application and put everything -- all source and header files-- into one big file. Compile time dropped from 3 hours to 7 minutes.

I have had LOTS of issues with the spinner firing of when I didn't want to, and all the answers here are unreliable. They work - but only sometimes. You will eventually run into scenarios where they will fail and introduce bugs into your code.

What worked for me was to store the last selected index in a variable and evaluate it in the listener. If it is the same as the new selected index do nothing and return, else continue with the listener. Do this:

//Declare a int member variable and initialize to 0 (at the top of your class)
private int mLastSpinnerPosition = 0;

//then evaluate it in your listener
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {

  if(mLastSpinnerPosition == i){
        return; //do nothing
  }

  mLastSpinnerPosition = i;
  //do the rest of your code now

}

Trust me when I say this, this is by far the most reliable solution. A hack, but it works!

It is my solution for that:

onDelete(id: number) {
    this.service.delete(id).then(() => {
        let index = this.documents.findIndex(d => d.id === id); //find index in your array
        this.documents.splice(index, 1);//remove element from array
    });

    event.stopPropagation();
}

One line below should be what you looking for

if your file is in repository

![ScreenShot](https://raw.github.com/{username}/{repository}/{branch}/{path})

if your file is in other external url

![ScreenShot](https://{url})

There's Bash regular expressions. Or there's 'expr':

 if expr "$link" : '/.*' > /dev/null; then
    PRG="$link"
  else
    PRG=`dirname "$PRG"`/"$link"
  fi

The best answer is...

Don't use a regex

The expression in the accepted answer misses many cases. Among other things, URLs can have unicode characters in them. The regex you want is here, and after looking at it, you may conclude that you don't really want it after all. The most correct version is ten-thousand characters long.

Admittedly, if you were starting with plain, unstructured text with a bunch of URLs in it, then you might need that ten-thousand-character-long regex. But if your input is structured, use the structure. Your stated aim is to "extract the url, inside the anchor tag's href." Why use a ten-thousand-character-long regex when you can do something much simpler?

Parse the HTML instead

For many tasks, using Beautiful Soup will be far faster and easier to use:

>>> from bs4 import BeautifulSoup as Soup
>>> html = Soup(s, 'html.parser')           # Soup(s, 'lxml') if lxml is installed
>>> [a['href'] for a in html.find_all('a')]
['http://example.com', 'http://example2.com']

If you prefer not to use external tools, you can also directly use Python's own built-in HTML parsing library. Here's a really simple subclass of HTMLParser that does exactly what you want:

from html.parser import HTMLParser

class MyParser(HTMLParser):
    def __init__(self, output_list=None):
        HTMLParser.__init__(self)
        if output_list is None:
            self.output_list = []
        else:
            self.output_list = output_list
    def handle_starttag(self, tag, attrs):
        if tag == 'a':
            self.output_list.append(dict(attrs).get('href'))

Test:

>>> p = MyParser()
>>> p.feed(s)
>>> p.output_list
['http://example.com', 'http://example2.com']

You could even create a new method that accepts a string, calls feed, and returns output_list. This is a vastly more powerful and extensible way than regular expressions to extract information from html.

An expression of non-boolean type specified in a context where a condition is expected

I also got this error when I forgot to add ON condition when specifying my join clause.

Just an update to the answer of @rafa.pereira. Since ggplot2 is part of tidyverse, it makes sense to use the convenient tidyverse functions to get rid of NAs.

library(tidyverse)
airquality %>% 
        drop_na(Ozone) %>%
        ggplot(aes(x = Ozone))+
        geom_bar(stat="bin")

Note that you can also use drop_na() without columns specification; then all the rows with NAs in any column will be removed.

Our resident maestro Jon Skeet has a great Range Class that can do this for DateTimes and other types.

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

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

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

Java does not have a datatype for unsigned integers.

You can define a long instead of an int if you need to store large values.

You can also use a signed integer as if it were unsigned. The benefit of two's complement representation is that most operations (such as addition, subtraction, multiplication, and left shift) are identical on a binary level for signed and unsigned integers. A few operations (division, right shift, comparison, and casting), however, are different. As of Java SE 8, new methods in the Integer class allow you to fully use the int data type to perform unsigned arithmetic:

In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 2^32-1. Use the Integer class to use int data type as an unsigned integer. Static methods like compareUnsigned, divideUnsigned etc have been added to the Integer class to support the arithmetic operations for unsigned integers.

Note that int variables are still signed when declared but unsigned arithmetic is now possible by using those methods in the Integer class.

There is a free library called barcode4j

def myfunc(a,b):
    c = a.intersection(b)
    return bool(c)

bool() will do something similar to not not, but more ideomatic and clear.

If you don't mind the boolean being converted to a number (that is either 0 or 1), you can use the Bitwise XOR Assignment Operator. Like so:

bool ^= true;   //- toggle value.

This is especially good if you use long, descriptive boolean names, EG:

var inDynamicEditMode   = true;     // Value is: true (boolean)
inDynamicEditMode      ^= true;     // Value is: 0 (number)
inDynamicEditMode      ^= true;     // Value is: 1 (number)
inDynamicEditMode      ^= true;     // Value is: 0 (number)

This is easier for me to scan than repeating the variable in each line.

This method works in all (major) browsers (and most programming languages).

In core-site.xml:

    <configuration>
       <property>
          <name>fs.defaultFS</name>
          <value>hdfs://localhost:9000</value>
       </property>
       <property>
          <name>hadoop.tmp.dir</name>
          <value>/home/yourusername/hadoop/tmp/hadoop-${user.name}
         </value>
  </property>
</configuration>

and format of namenode with :

hdfs namenode -format

If you need to create a user_id then it would be a reasonable assumption that you are referencing a user table. In which case the migration shall be:

rails generate migration AddUserRefToProducts user:references

This command will generate the following migration:

class AddUserRefToProducts < ActiveRecord::Migration
  def change
    add_reference :user, :product, index: true
  end
end

After running rake db:migrate both a user_id column and an index will be added to the products table.

In case you just need to add an index to an existing column, e.g. name of a user table, the following technique may be helpful:

rails generate migration AddIndexToUsers name:string:index will generate the following migration:

class AddIndexToUsers < ActiveRecord::Migration
  def change
    add_column :users, :name, :string
    add_index :users, :name
  end
end

Delete add_column line and run the migration.

In the case described you could have issued rails generate migration AddIndexIdToTable index_id:integer:index command and then delete add_column line from the generated migration. But I'd rather recommended to undo the initial migration and add reference instead:

rails generate migration RemoveUserIdFromProducts user_id:integer
rails generate migration AddUserRefToProducts user:references

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

I find that document.getElementById('textbox-id').readOnly=true sometimes doesn't work reliably.

Instead, try:

document.getElementById('textbox-id').setAttribute('readonly', 'readonly') and document.getElementById('textbox-id').removeAttribute('readonly').

A little verbose but it seems to be dependable.

I use them sometimes as a syntax hack for Map instantiation:

Map map = new HashMap() {{
   put("key", "value");
}};

vs

Map map = new HashMap();
map.put("key", "value");

It saves some redundancy when doing a lot of put statements. However, I have also run into problems doing this when the outer class needs to be serialized via remoting.

Do you know pit?

https://pypi.python.org/pypi/pit (py2 only (version 0.3))

https://github.com/yoshiori/pit (it will work on py3 (current version 0.4))

test.py

from pit import Pit

config = Pit.get('section-name', {'require': {
    'username': 'DEFAULT STRING',
    'password': 'DEFAULT STRING',
    }})
print(config)

Run:

$ python test.py
{'password': 'my-password', 'username': 'my-name'}

~/.pit/default.yml:

section-name:
  password: my-password
  username: my-name

Just for completeness. There is another situation causing this error:

missing META-INF/services/javax.persistence.spi.PersistenceProvider file.

For Hibernate, it's located in hibernate-entitymanager-XXX.jar, so, if hibernate-entitymanager-XXX.jar is not in your classpath, you will got this error too.

This error message is so misleading, and it costs me hours to get it correct.

See JPA 2.0 using Hibernate as provider - Exception: No Persistence provider for EntityManager.

Select your required commit, and check it by

git show HEAD
git show HEAD~1
git show HEAD~2 

till you get the required commit. To make the HEAD point to that, do

git reset --hard HEAD~1

or git reset --hard HEAD~2 or whatever.

You can do it with PhantomJSDriver.

PhantomJSDriver pd = ((PhantomJSDriver) ((WebDriverFacade) getDriver()).getProxiedDriver());
pd.executePhantomJS(
            "this.onResourceRequested = function(request, net) {" +
            "   net.setHeader('header-name', 'header-value')" +
            "};");

Using the request object, you can filter also so the header won't be set for every request.

add this to your css:

.carousel-inner > .item > img, .carousel-inner > .item > a > img {
    width: 100%;
}

You can use the deprecated AppDomain.GetCurrentThreadId to get the ID of the currently running thread. This method uses a PInvoke to the Win32 API method GetCurrentThreadID, and will return the Windows thread ID.

This method is marked as deprecated because the .NET Thread object does not correspond to a single Windows thread, and as such there is no stable ID which can be returned by Windows for a given .NET thread.

See configurator's answer for more reasons why this is the case.

I found 'running steps' (win32) software doing exactly what I was looking for: http://www.steppingsoftware.com/

You can load a bat file, place breakpoints / start stepping through it while seeing the output and environment variables.

The evaluation version only allows to step through 50 lines... Does anyone have a free alternative with similar functionality?

Real-time is the highest priority class available to a process. Therefore, it is different from 'High' in that it's one step greater, and 'Above Normal' in that it's two steps greater.

Similarly, real-time is also a thread priority level.

The process priority class raises or lowers all effective thread priorities in the process and is therefore considered the 'base priority'.

So, a process has a:

1. Base process priority class.
2. Individual thread priorities, offsets of the base priority class.

Since real-time is supposed to be reserved for applications that absolutely must pre-empt other running processes, there is a special security privilege to protect against haphazard use of it. This is defined by the security policy.

In NT6+ (Vista+), use of the Vista Multimedia Class Scheduler is the proper way to achieve real-time operations in what is not a real-time OS. It works, for the most part, though is not perfect since the OS isn't designed for real-time operations.

Microsoft considers this priority very dangerous, rightly so. No application should use it except in very specialized circumstances, and even then try to limit its use to temporary needs.

A simple example:

const strArr = ["red", "green", "blue", "black"];

const strGen = function*() {
    for(let str of strArr) {
        yield str;
    }
};

let gen = strGen();

for (let i = 0; i < 5; i++) {
    console.log(gen.next())
}

//prints: {value: "red", done: false} -> 5 times with different colors, if you try it again as below:

console.log(gen.next());

//prints: {value: undefined, done: true}

Your E class doesn't have a member of type struct X, you've just defined a nested struct X in there (i.e. you've defined a new type).

Try:

#include <iostream>

class E
{
    public: 
    struct X { int v; };
    X x; // an instance of `struct X`
};

int main(){

    E object;
    object.x.v = 1;

    return 0;
}

I agree that using the global/GLOBAL namespace for setting anything global is bad practice and don't use it at all in theory (in theory being the operative word). However (yes, the operative) I do use it for setting custom Error classes:

// Some global/configuration file that gets called in initialisation

global.MyError = [Function of MyError];

Yes, it is taboo here, but if your site/project uses custom errors throughout the place, you would basically need to define it everywhere, or at least somewhere to:

1. Define the Error class in the first place
2. In the script where you're throwing it
3. In the script where you're catching it

Defining my custom errors in the global namespace saves me the hassle of require'ing my customer error library. Imaging throwing a custom error where that custom error is undefined.

In a previous project I found that changing from *-imports to specific imports reduced compilation time by half (from about 10 minutes to about 5 minutes). The *-import makes the compiler search each of the packages listed for a class matching the one you used. While this time can be small, it adds up for large projects.

A side affect of the *-import was that developers would copy and paste common import lines rather than think about what they needed.

os.path.isfile("bob.txt") # Does bob.txt exist?  Is it a file, or a directory?
os.path.isdir("bob")

Vue allows for you to specify a default prop value and type directly, by making props an object (see: https://vuejs.org/guide/components.html#Prop-Validation):

props: {
  year: {
    default: 2016,
    type: Number
  }
}

If the wrong type is passed then it throws an error and logs it in the console, here's the fiddle:

https://jsfiddle.net/cexbqe2q/

How about just multiplying by one like this?

var x = 1.234000*1; // becomes 1.234

var y = 1.234001*1; // stays as 1.234001

For me shutil.copy is the best:

import shutil

#make a copy of the invoice to work with
src="invoice.pdf"
dst="copied_invoice.pdf"
shutil.copy(src,dst)

You can change the path of the files as you want.

All the hidden fields in your fieldset are using the same id, so jquery is only returning the first one. One way to fix this is to create a counter variable and concatenate it to each hidden field id.

In case anyone is interested in a general one-liner, simply get the current ticks and use it to set the new ticks by sampling every other tick.

ax.set_xticks(ax.get_xticks()[::2])

>>> print then.date(), type(then.date())
2013-05-07 <type 'datetime.date'>

I just wanted to hop in here and correct (suggest alternative) to the previous answer....

You can actually use compact in the same way, however a lot neater for example...

return View::make('gameworlds.mygame', compact(array('fixtures', 'teams', 'selections')));

Or if you are using PHP > 5.4

return View::make('gameworlds.mygame', compact(['fixtures', 'teams', 'selections']));

This is far neater, and still allows for readability when reviewing what the application does ;)
