My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/

IN this answer when i say a file i mean the location in memory

All the data that is saved is stored in memory using a data structure called inodes Every inode has a inodenumber.The inode number is used to access the inode.All the hard links to a file may have different names but share the same inode number.Since all the hard links have the same inodenumber(which inturn access the same inode),all of them point to the same physical memory.

A symbolic link is a special kind of file.Since it is also a file it will have a file name and an inode number.As said above the inode number acceses an inode which points to data.Now what makes a symbolic link special is that the inodenumbers in symbolic links access those inodes which point to "a path" to another file.More specifically the inode number in symbolic link acceses those inodes who point to another hard link.

when we are moving,copying,deleting a file in GUI we are playing with the hardlinks of the file not the physical memory.when we delete a file we are deleting the hardlink of the file. we are not wiping out the physical memory.If all the hardlinks to file are deleted then it will not be possible to access the data stored although it may still be present in memory

Not an equivalent, but you can use a Scanner and a pattern to parse lines with three non-negative numbers separated by spaces, for example:

71 5796 2489
88 1136 5298
42 420 842

Here's the code using findAll:

new Scanner(System.in).findAll("(\\d+) (\\d+) (\\d+)")
        .forEach(result -> {
            int fst = Integer.parseInt(result.group(1));
            int snd = Integer.parseInt(result.group(2));
            int third = Integer.parseInt(result.group(3));
            int sum = fst + snd + third;
            System.out.printf("%d + %d + %d = %d", fst, snd, third, sum);
        });

Solution

1. Create new UNIQUE key that is identical to your current PRIMARY key
2. Add new column id is unsigned integer, auto_increment
3. Create primary key on new id column

Bam, immediate 10x+ insert improvement.

Using styling from CSS, you can define how something is positioned. If you define the element as fixed, it will always remain in the same position on the screen at all times.

div
{
    position:fixed;
    top:20px;
}

Per the comments to the original post, merges / joins are well-suited for this problem. In particular, an inner join will return only values that are present in both dataframes, making thesetdiff statement unnecessary.

Using the data from Dinre's example:

In base R:

cleanedA <- merge(data_A, data_B[, "index"], by = 1, sort = FALSE)
cleanedB <- merge(data_B, data_A[, "index"], by = 1, sort = FALSE)

Using the dplyr package:

library(dplyr)
cleanedA <- inner_join(data_A, data_B %>% select(index))
cleanedB <- inner_join(data_B, data_A %>% select(index))

To keep the data as two separate tables, each containing only its own variables, this subsets the unwanted table to only its index variable before joining. Then no new variables are added to the resulting table.

Python 3

• class MyClass(object): = New-style class
• class MyClass: = New-style class (implicitly inherits from object)

Python 2

• class MyClass(object): = New-style class
• class MyClass: = OLD-STYLE CLASS

Explanation:

When defining base classes in Python 3.x, you’re allowed to drop the object from the definition. However, this can open the door for a seriously hard to track problem…

Python introduced new-style classes back in Python 2.2, and by now old-style classes are really quite old. Discussion of old-style classes is buried in the 2.x docs, and non-existent in the 3.x docs.

The problem is, the syntax for old-style classes in Python 2.x is the same as the alternative syntax for new-style classes in Python 3.x. Python 2.x is still very widely used (e.g. GAE, Web2Py), and any code (or coder) unwittingly bringing 3.x-style class definitions into 2.x code is going to end up with some seriously outdated base objects. And because old-style classes aren’t on anyone’s radar, they likely won’t know what hit them.

So just spell it out the long way and save some 2.x developer the tears.

Use dispatch group

dispatchGroup.enter()
FirstOperation(completion: { _ in
    dispatchGroup.leave()
})
dispatchGroup.enter()
SecondOperation(completion: { _ in
    dispatchGroup.leave()
})
dispatchGroup.wait() // Waits here on this thread until the two operations complete executing.

In the Case of Apache HTTP client deprecation (From Google ) : With Android 6.0, we removed support for the Apache HTTP client. Beginning with Android 9, that library is removed from the bootclasspath and is not available to apps by default. To continue using the Apache HTTP client, apps that target Android 9 and above can add the following to their AndroidManifest.xml:

ctrl+c and kill -INT <pid> are not exactly the same, to emulate ctrl+c we need to first understand the difference.

kill -INT <pid> will send the INT signal to a given process (found with its pid).

ctrl+c is mapped to the intr special character which when received by the terminal should send INT to the foreground process group of that terminal. You can emulate that by targetting the group of your given <pid>. It can be done by prepending a - before the signal in the kill command. Hence the command you want is:

kill -INT -<pid>

You can test it pretty easily with a script:

#!/usr/bin/env ruby

fork {
    trap(:INT) {
        puts 'signal received in child!'
        exit
    }
    sleep 1_000
}

puts "run `kill -INT -#{Process.pid}` in any other terminal window."
Process.wait

You need to use arguments unpacking..

def wrapper(func, *args):
    func(*args)

def func1(x):
    print(x)

def func2(x, y, z):
    print x+y+z

wrapper(func1, 1)
wrapper(func2, 1, 2, 3)

For DB2, the syntax is:

ALTER TABLE one ADD two_id INTEGER FOREIGN KEY (two_id) REFERENCES two (id);

If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:

• Start your intellij from terminal /Applications/IntelliJ IDEA 14.app/Contents/MacOS (this will pick your bash env variables)
• Add login env variable by executing: launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"

To directly answer your question, you can add launchctl line in your ~/.bash_profile

As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.

just came across while browsing, might help you javascript-getting-and-setting-caret-position-in-textarea. You can use it for textbox also.

Turns out there's no good way of doing this. The closest I came is adding "overflow:hidden;" to the div around the table and losing the text. The real solution seems to be to ditch table though. Using divs and relative positioning I was able to achieve the same effect, minus the legacy of <table>

2015 UPDATE: This is for those like me who want this answer. After 6 years, this works, thanks to all the contributors.

* { // this works for all but td
  word-wrap:break-word;
}

table { // this somehow makes it work for td
  table-layout:fixed;
  width:100%;
}

I had the same problem and wanted to change the product key to another. Unfortunate it's not as easy as it was on VS2010.

The following steps work:

• Remove the registry key containing the license information: HKEY_CLASSES_ROOT\Licenses\77550D6B-6352-4E77-9DA3-537419DF564B

• If you can't find the key, use sysinternals ProcessMonitor to check the registry access of VS2012 to locate the correct key which is always in HKEY_CLASSES_ROOT\Licenses

• After you remove this key, VS2012 will tell you that it's license information is incorrect. Go to "Programs and features" and repair VS2012.

• After the repair, VS2012 is reverted to a 30 day trial and you can enter a new product key. This could also be used to stay in a trial version loop and never enter a producy key.

As the error message states, jQuery does not include a :unchecked selector.
Instead, you need to invert the :checked selector:

$("input:checkbox:not(:checked)")

If you need your SVGs to be fully styleable with CSS they have to be inline in the DOM. This can be achieved through SVG injection, which uses Javascript to replace a HTML element (usually an <img> element) with the contents of an SVG file after the page has loaded.

Here is a minimal example using SVGInject:

<html>
<head>
  <script src="svg-inject.min.js"></script>
</head>
<body>
  <img src="image.svg" onload="SVGInject(this)" />
</body>
</html>

After the image is loaded the onload="SVGInject(this) will trigger the injection and the <img> element will be replaced by the contents of the file provided in the src attribute. This works with all browsers that support SVG.

Disclaimer: I am the co-author of SVGInject

IT happens with me when I rename my project/solution. Go to the folder of project in windows explorer (get out of VS). Find and open the file Global (maybe you'll find 2 files, open that dont have ".asax.cs" extension), and edit the line of error with correct path. Good luck!

dict((el,0) for el in a) will work well.

Python 2.7 and above also support dict comprehensions. That syntax is {el:0 for el in a}.

As stated before I even saw this question placeholder is the answer. HTML5 for the win! But for those poor unfortunate souls that cannot rely on that functionality take a look at the jquery plugin as an augmentation as well. HTML5 Placeholder jQuery Plugin

<input name="Name" placeholder="Enter Your Name">

After looking at all the suggestions here, I've discovered a few things which I hope will be useful to others in my position:

1. hop is right to point me back at /etc/init.d/functions: the daemon function already allows you to set an alternate user:

   daemon --user=my_user my_cmd &>/dev/null &
   

   This is implemented by wrapping the process invocation with runuser - more on this later.

2. Jonathan Leffler is right: there is setuid in Python:

   import os
   os.setuid(501) # UID of my_user is 501
   

   I still don't think you can setuid from inside a JVM, however.

3. Neither su nor runuser gracefully handle the case where you ask to run a command as the user you already are. E.g.:

   [my_user@my_host]$ id
   uid=500(my_user) gid=500(my_user) groups=500(my_user)
   [my_user@my_host]$ su my_user -c "id"
   Password: # don't want to be prompted!
   uid=500(my_user) gid=500(my_user) groups=500(my_user)
   

To workaround that behaviour of su and runuser, I've changed my init script to something like:

if [[ "$USER" == "my_user" ]]
then
    daemon my_cmd &>/dev/null &
else
    daemon --user=my_user my_cmd &>/dev/null &
fi

Thanks all for your help!

Setting an Initial Catalog allows you to set the database that queries run on that connection will use by default. If you do not set this for a connection to a server in which multiple databases are present, in many cases you will be required to have a USE statement in every query in order to explicitly declare which database you are trying to run the query on. The Initial Catalog setting is a good way of explicitly declaring a default database.

As well as find listed in other answers, better shells allow both recurvsive globs and filtering of glob matches, so in zsh for example...

ls -lad **/*(/)

...lists all directories while keeping all the "-l" details that you want, which you'd otherwise need to recreate using something like...

find . -type d -exec ls -ld {} \;

(not quite as easy as the other answers suggest)

The benefit of find is that it's more independent of the shell - more portable, even for system() calls from within a C/C++ program etc..

Your problem is in your php file. When you use jquery serialize() method you are sending a string, so you can not treat it like an array. Make a var_dump($_post) and you will see what I am talking about.

UPDATE mytbl
SET a = ABS(a)
where a < 0

I saw it's solved, but I still want to share a solution which worked for me.

.env file:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=[your database name]
DB_USERNAME=[your MySQL username]
DB_PASSWORD=[your MySQL password]

MySQL admin:

 SELECT user, host FROM mysql.user

Thank you, spencer7593

Console:

php artisan cache:clear
php artisan config:cache

Now it works for me.

title is a local variable. They only exists within its scope (current block)

@title is an instance variable - and is available to all methods within the class.

You can read more here: http://strugglingwithruby.blogspot.dk/2010/03/variables.html

In Ruby on Rails - declaring your variables in your controller as instance variables (@title) makes them available to your view.

Protected Member

Protected Member of a class in only available in the contained class (in which it has been declared) and in the derived class within the assembly and also outside the assembly.

Means if a class that resides outside the assembly can use the protected member of the other assembly by inherited that class only.

We can exposed the Protected member outside the assembly by inherited that class and use it in the derived class only.

Note: Protected members are not accessible using the object in the derived class.

Internal Member

Internal Member of a class is available or access within the assembly either creating object or in a derived class or you can say it is accessible across all the classes within the assembly.

Note: Internal members not accessible outside the assembly either using object creating or in a derived class.

Protected Internal

Protected Internal access modifier is combination Protected or Internal.

Protected Internal Member can be available within the entire assembly in which it declared either creating object or by inherited that class. And can be accessible outside the assembly in a derived class only.

Note: Protected Internal member works as Internal within the same assembly and works as Protected for outside the assembly.

If you don't want to put @SuppressWarning("unchecked") on each sf.getEntries() call, you can always make a wrapper that will return List.

You can now use the CSS filter property in most modern browsers (including Edge, but not IE11). It works on SVG images as well as other elements. You can use hue-rotate or invert to modify colors, although they don't let you modify different colors independently. I use the following CSS class to show a "disabled" version of an icon (where the original is an SVG picture with saturated color):

.disabled {
    opacity: 0.4;
    filter: grayscale(100%);
    -webkit-filter: grayscale(100%);
}

This makes it light grey in most browsers. In IE (and probably Opera Mini, which I haven't tested) it is noticeably faded by the opacity property, which still looks pretty good, although it's not grey.

Here's an example with four different CSS classes for the Twemoji bell icon: original (yellow), the above "disabled" class, hue-rotate (green), and invert (blue).

.twa-bell {_x000D_
  background-image: url("https://twemoji.maxcdn.com/svg/1f514.svg");_x000D_

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

This will also work fine with double quotes. To echo any html_tag with double quotes we just need to remember one thing, Do not use any other double quotes(") in the middle.

<?php
    echo "
    <div>
        <h3><a href='https://stackoverflow.com/questions/3931351/how-to-echo-in-php-html-tags'>First</a></h3>
        <div>Lorem ipsum dolor sit amet.</div>
        </div>
    <div>";
?>

Notice here the link inside the PHP echo is enclosed within the single quotes. This is the precaution you should take while using the double quotes for this purpose.

Let's say your primary key is an Integer and the object you save is "ticket", then you can get it like this. When you save the object, a Serializable id is always returned

Integer id = (Integer)session.save(ticket);

class Array
  def sum 
    inject( nil ) { |sum,x| sum ? sum+x : x }
  end

  def mean 
    sum.to_f / size.to_f
  end
end

[0,4,8,2,5,0,2,6].mean

To do this we need the "Facebook page id", you can get it :

• from the page go to "About".
• go to "More Info" section.

To opening facebook app on specified profile page,

you can do this:

 String facebookId = "fb://page/<Facebook Page ID>";
  startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId)));

Or you can validate when the facebook app is not installed, then open the facebook web page.

String facebookId = "fb://page/<Facebook Page ID>";
String urlPage = "http://www.facebook.com/mypage";

     try {
          startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId )));
        } catch (Exception e) {
         Log.e(TAG, "Application not intalled.");
         //Open url web page.
         startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(urlPage)));
        }

You can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

# HTTP POST variables
request.POST['section'] # => [39]
request.POST['MAINS'] # => [137]

# HTTP GET variables
request.GET['section'] # => [39]
request.GET['MAINS'] # => [137]

# HTTP POST and HTTP GET variables (Deprecated since Django 1.7)
request.REQUEST['section'] # => [39]
request.REQUEST['MAINS'] # => [137]

As previous answers, there is no standard API in Java for this.

You can add groovy jar files to your path and groovy.util.Eval.me("4*5") gets your job done.

This should do it, all of this is in the documentation, which has a very similar example to this:

$("input[type='radio'][name='theme']").click(function() {
    var value = $(this).val();
});

I should also note you have multiple identical IDs in that snippet. This is invalid HTML. Use classes to group set of elements, not IDs, as they should be unique.

log simply takes the logarithm (base e, by default) of each element of the vector.
scale, with default settings, will calculate the mean and standard deviation of the entire vector, then "scale" each element by those values by subtracting the mean and dividing by the sd. (If you use scale(x, scale=FALSE), it will only subtract the mean but not divide by the std deviation.)

Note that this will give you the same values

   set.seed(1)
   x <- runif(7)

   # Manually scaling
   (x - mean(x)) / sd(x)

   scale(x)

From MSDN
$0 - "Substitutes the last substring matched by group number number (decimal)."

In .NET Regular expressions group 0 is always the entire match. For a literal $ you need to

string value = Regex.Replace("%PolicyAmount%", "%PolicyAmount%", @"$$0", RegexOptions.IgnoreCase);

Just use:

$('#selectedDueDate').val(dateText).trigger('input');

instead of:

$('#selectedDueDate').val(dateText);

I met the problem in another reason.

I was building app in Android Studio, and I had a app module and another module. App module depended on the other module.

But part of build.gradle of app module is :

<application
    android:allowBackup="false"
    android:label="@string/app_name"
    android:supportsRtl="true">

    ...

</application>

while the other module's build.gradle part is:

<application
    android:allowBackup="true"
    android:label="Android Lua"
    android:supportsRtl="true">

</application>

So, I change the module's build.gradle part to:

<application
    android:allowBackup="false"
    android:label="@string/app_name"
    android:supportsRtl="true">

</application>

Problem solved.

Please forgive me

But I think a public open-source repository is a better way to share code and make contributions, and corrections, and additions like "I fixed this, I fixed that"

So I made a simple git-repository out of the topic-starter's code and all the additions:

https://github.com/jitbit/CsvExport

I also added a couple of useful fixes myself. Everyone could add suggestions, fork it to contribute etc. etc. etc. Send me your forks so I merge them back into the repo.

PS. I posted all copyright notices for Chris. @Chris if you're against this idea - let me know, I'll kill it.

I allways use UPPER(text) like UPPER('%blah%')

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

Use innerHTML instead

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

For multiline text this answer is not working correctly. You can build a different String extension by using UILabel

extension String {
func height(constraintedWidth width: CGFloat, font: UIFont) -> CGFloat {
    let label =  UILabel(frame: CGRect(x: 0, y: 0, width: width, height: .greatestFiniteMagnitude))
    label.numberOfLines = 0
    label.text = self
    label.font = font
    label.sizeToFit()

    return label.frame.height
 }
}

The UILabel gets a fixed width and the .numberOfLines is set to 0. By adding the text and calling .sizeToFit() it automatically adjusts to the correct height.

Code is written in Swift 3

To populate a List of String, you need not use custom row mapper. Implement it using queryForList.

List<String>data=jdbcTemplate.queryForList(query,String.class)

To complete the answer :

1. The Java File

   TheJavaFile.java
   

2. Compile the Java File to a *.class file

   javac TheJavaFile.java
   

   • This will create a TheJavaFile.class file

3. Execution of the Java File

   java TheJavaFile
   

4. Creation of an executable *.jar file

   • You've got two options here -

     1. With an external manifest file :

        • Create the manifest file say - MANIFEST.mf

        • The MANIFEST file is nothing but an explicit entry of the Main Class

        • jar -cvfm TheJavaFile.jar MANIFEST.mf TheJavaFile.class

     2. Executable by Entry Point:

        • jar -cvfe TheJavaFile.jar <MainClass> TheJavaFile.class

5. To run the Jar File

   java -jar TheJavaFile.jar
   

If you start mysql as "mysql -u -p --local-infile ", it will work fine

I somehow achieved this by knowing the status of the soft keyboard on the device. i move the layout to y position when the keyboard is shown and moved back to its original position when not shown. this works fine, followed this guidelines.

If the user should select only one option at once, just remove the "multiple" - make a normal select:

  <select name="mySelect" size="3">
     <option>Foo</option>
     <option>Bar</option>
     <option>Foo Bar</option>
     <option>Bar Foo</option>
  </select>

Fiddle

if name in ("Jesse", "jesse"):

would be the correct way to do it.

Although, if you want to use or, the statement would be

if name == 'Jesse' or name == 'jesse':

>>> ("Jesse" or "jesse")
'Jesse'

evaluates to 'Jesse', so you're essentially not testing for 'jesse' when you do if name == ("Jesse" or "jesse"), since it only tests for equality to 'Jesse' and does not test for 'jesse', as you observed.

understanding the context of SDLC will help understand the difference between snapshot and the release. During the dev process developers all contribute their features to a baseline branch. At some point the lead thinks enough features have accumulated then he will cut a release branch from the baseline branch. Any builds prior to this time point are snapshots. Builds post to this point are releases. Be noted, release builds could change too before going to production if any defect spot during the release testing.

If you just want to see the values of an array without brackets, you can use a combination of fmt.Sprint() and strings.Trim()

a := []string{"a", "b"}
fmt.Print(strings.Trim(fmt.Sprint(a), "[]"))
fmt.Print(a)

Returns:

a b
[a b]

Be aware though that with this solution any leading brackets will be lost from the first value and any trailing brackets will be lost from the last value

a := []string{"[a]", "[b]"}
fmt.Print(strings.Trim(fmt.Sprint(a), "[]")
fmt.Print(a)

Returns:

a] [b
[[a] [b]]

For more info see the documentation for strings.Trim()

If you know the (maximum) number of rows and columns beforehand, you can use resize() to initialize a vector of vectors and then modify (and access) elements with operator[]. Example:

int no_of_cols = 5;
int no_of_rows = 10;
int initial_value = 0;

std::vector<std::vector<int>> matrix;
matrix.resize(no_of_rows, std::vector<int>(no_of_cols, initial_value));

// Read from matrix.
int value = matrix[1][2];

// Save to matrix.
matrix[3][1] = 5;

Another possibility is to use just one vector and split the id in several variables, access like vector[(row * columns) + column].

After the C# 6.0 (including) you can use nameof expression:

using Stuff = Some.Cool.Functionality  
class C {  
    static int Method1 (string x, int y) {}  
    static int Method1 (string x, string y) {}  
    int Method2 (int z) {}  
    string f<T>() => nameof(T);  
}  

var c = new C()  

nameof(C) -> "C"  
nameof(C.Method1) -> "Method1"   
nameof(C.Method2) -> "Method2"  
nameof(c.Method1) -> "Method1"   
nameof(c.Method2) -> "Method2"  
nameof(z) -> "z" // inside of Method2 ok, inside Method1 is a compiler error  
nameof(Stuff) = "Stuff"  
nameof(T) -> "T" // works inside of method but not in attributes on the method  
nameof(f) -> “f”  
nameof(f<T>) -> syntax error  
nameof(f<>) -> syntax error  
nameof(Method2()) -> error “This expression does not have a name”  

Note! nameof not get the underlying object's runtime Type, it is just the compile-time argument. If a method accepts an IEnumerable then nameof simply returns "IEnumerable", whereas the actual object could be "List".

Code Behind :

       private IEnumerable<DataGridRow> GetDataGridRowsForButtons(DataGrid grid)
{ //IQueryable 
    var itemsSource = grid.ItemsSource as IEnumerable;
    if (null == itemsSource) yield return null;
    foreach (var item in itemsSource)
    {
        var row = grid.ItemContainerGenerator.ContainerFromItem(item) as DataGridRow;
        if (null != row & row.IsSelected) yield return row;
    }
}

void Button_Click_dgvs(object sender, RoutedEventArgs e)
{

    for (var vis = sender as Visual; vis != null; vis = VisualTreeHelper.GetParent(vis) as Visual)
        if (vis is DataGridRow)
        {
           // var row = (DataGrid)vis;

            var rows = GetDataGridRowsForButtons(dgv_Students);
            string id;
            foreach (DataGridRow dr in rows)
            {
                id = (dr.Item as tbl_student).Identification_code;
                MessageBox.Show(id);
                 break;
            }
            break;
        }
}

After clicking on the Button, the ID of that row is returned to you and you can use it for your Button name.

Simple solution

{{ orderTotal | number : '1.2-2'}}

//output like this

// public orderTotal = 220.45892221

//   {{ orderTotal | number : '1.2-2'}} 

// final Output
//  220.45

String output = "";
    HashMap<Character,Boolean> map = new HashMap<>();
    for(int i=0;i<str.length();i++){
        char ch = str.charAt(i);
        if (!map.containsKey(ch)){
            output += ch;
            map.put(ch,true);
        }
    }
    return output;

This is the simple approach using HashMap in Java in one pass .

The problem is not with the import statement. The problem is that the control flow statements don't work inlined in a python command. Replace that import statement with any other statement and you'll see the same problem.

Think about it: python can't possibly inline everything. It uses indentation to group control-flow.

I have created two Dockerfiles in same directory,

# vi one.Dockerfile
# vi two.Dockerfile

to build both Dockerfiles use,

# docker build . -f one.Dockerfile
# docker build . -f two.Dockerfile

Note: you should be in present working directory..

Even better:

student_tuples = [
    ('john', 'A', 15),
    ('jane', 'B', 12),
    ('dave', 'B', 10),
]

sorted(student_tuples, key=lambda student: student[2])   # sort by age
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]

I see steps are scattered in different answers. Based on my recent experience with this pytesseract error on Windows, writing different steps in sequence to make it easier to resolve the error:

1. Install tesseract using windows installer available at: https://github.com/UB-Mannheim/tesseract/wiki

2. Note the tesseract path from the installation. Default installation path at the time of this edit was: C:\Users\USER\AppData\Local\Tesseract-OCR. It may change so please check the installation path.

3. pip install pytesseract

4. Set the tesseract path in the script before calling image_to_string:

pytesseract.pytesseract.tesseract_cmd = r'C:\Users\USER\AppData\Local\Tesseract-OCR\tesseract.exe'

When it is the case that you want to use any kind of external file, there is certainly a way to put them in a folder within your project, but not as valid as getting them from resources. In a regular Visual Studio project, you should have a Resources.resx file under the Properties section, if not, you can easily add your own Resource.resx file. And add any kind of file in it, you can reach the walkthrough for adding resource files to your project here.

After having resource files in your project, calling them is easy as this:

var myIcon = Resources.MyIconFile;

Of course you should add the using Properties statement like this:

using <namespace>.Properties;

This can be done by cloning to a new directory, then moving the .git directory into your existing directory.

If your existing directory is named "code".

git clone https://myrepo.com/git.git temp
mv temp/.git code/.git
rm -rf temp

This can also be done without doing a checkout during the clone command; more information can be found here.

Another alternative with data.table.

EXAMPLE DATA

dt1 <- data.table(df1)

for /r %%v in (*.xls) do ssconvert "%%v" "%%vx"

a couple have people have asked me to explain this, so:

Part 1: for /r %%v in (*.xls)

This part returns an array of files in the current directory that have the xls extension. The %% may look a little curious. This is basically the special % character from command line as used in %PATH% or %TEMP%. To use it in a batch file we need to escape it like so: %%PATH%% or %%TEMP%%. In this case we are simply escaping the temporary variable v, which will hold our array of filenames.

We are using the /r switch to search for files recursively, so any matching files in child folders will also be located.

Part 2: do ssconvert "%%v" "%%vx"

This second part is what will get executed once per matching filename, so if the following files were present in the current folder:

c:\temp\mySheet.xls, c:\temp\mySheet_yesterday.xls, c:\temp\mySheet_20160902.xls

the following commands would be executed:

ssconvert "c:\temp\mySheet.xls" "c:\temp\mySheet.xlsx" ssconvert "c:\temp\mySheet_yesterday.xls" "c:\temp\mySheet_yesterday.xlsx" ssconvert "c:\temp\mySheet_20160902.xls" "c:\temp\mySheet_20160902.xlsx"

@Eevee: As the browser becomes the home for richer and richer functionality and starts to replace desktop apps, it's just not going to be an option to forgo the use of keyboard shortcuts. Gmail's rich and intuitive set of keyboard commands was instrumental in my willingness to abandon Outlook. The keyboard shortcuts in Todoist, Google Reader, and Google Calendar all make my life much, much easier on a daily basis.

Developers should definitely be careful not to override keystrokes that already have a meaning in the browser. For example, the WMD textbox I'm typing into inexplicably interprets Ctrl+Del as "Blockquote" rather than "delete word forward". I'm curious if there's a standard list somewhere of "browser-safe" shortcuts that site developers can use and that browsers will commit to staying away from in future versions.

Depending on a number of factors, it may actually be faster to copy the list to an array and then use a Quicksort.

The reason this might be faster is that an array has much better cache performance than a linked list. If the nodes in the list are dispersed in memory, you may be generating cache misses all over the place. Then again, if the array is large you will get cache misses anyway.

Mergesort parallelises better, so it may be a better choice if that is what you want. It is also much faster if you perform it directly on the linked list.

Since both algorithms run in O(n * log n), making an informed decision would involve profiling them both on the machine you would like to run them on.

--- EDIT

I decided to test my hypothesis and wrote a C-program which measured the time (using clock()) taken to sort a linked list of ints. I tried with a linked list where each node was allocated with malloc() and a linked list where the nodes were laid out linearly in an array, so the cache performance would be better. I compared these with the built-in qsort, which included copying everything from a fragmented list to an array and copying the result back again. Each algorithm was run on the same 10 data sets and the results were averaged.

These are the results:

N = 1000:

Fragmented list with merge sort: 0.000000 seconds

Array with qsort: 0.000000 seconds

Packed list with merge sort: 0.000000 seconds

N = 100000:

Fragmented list with merge sort: 0.039000 seconds

Array with qsort: 0.025000 seconds

Packed list with merge sort: 0.009000 seconds

N = 1000000:

Fragmented list with merge sort: 1.162000 seconds

Array with qsort: 0.420000 seconds

Packed list with merge sort: 0.112000 seconds

N = 100000000:

Fragmented list with merge sort: 364.797000 seconds

Array with qsort: 61.166000 seconds

Packed list with merge sort: 16.525000 seconds

Conclusion:

At least on my machine, copying into an array is well worth it to improve the cache performance, since you rarely have a completely packed linked list in real life. It should be noted that my machine has a 2.8GHz Phenom II, but only 0.6GHz RAM, so the cache is very important.

I believe all the other answers should clear your doubts. Nevertheless, I just wanted to add that observables are based on functional programming, and I find very useful the functions that come with it like map, flatmap, reduce, zip. The consistency the web achieves especially when it depends on API requests is a brutal improvement.

I strongly recommend this documentation, since it's the official documentation of reactiveX and I find it to be the most clear out there.

If you want to get into observables, I would suggest this 3-part post: http://blog.danlew.net/2014/09/15/grokking-rxjava-part-1/

Although it's meant for RxJava, the concepts are the same, and it's really well explained. In reactiveX documentation, you have the equivalences for each function. You must look for RxJS.

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

1. Undo the local commit. This will just undo the commit and preserves the changes in working copy

git reset --soft HEAD~1

2. Pull the latest changes

git pull

3. Now you can commit your changes on top of latest code

Elements are added to list using append():

>>> data = {'list': [{'a':'1'}]}
>>> data['list'].append({'b':'2'})
>>> data
{'list': [{'a': '1'}, {'b': '2'}]}

If you want to add element to a specific place in a list (i.e. to the beginning), use insert() instead:

>>> data['list'].insert(0, {'b':'2'})
>>> data
{'list': [{'b': '2'}, {'a': '1'}]}

After doing that, you can assemble JSON again from dictionary you modified:

>>> json.dumps(data)
'{"list": [{"b": "2"}, {"a": "1"}]}'

Way1 :

@Entity

@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames = "column1"),@UniqueConstraint(columnNames = "column2")})

-- Here both Column1 and Column2 acts as unique constraints separately. Ex : if any time either the value of column1 or column2 value matches then you will get UNIQUE_CONSTRAINT Error.

Way2 :

@Entity

@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames ={"column1","column2"})})

-- Here both column1 and column2 combined values acts as unique constraints

So there 2 ways to create a dict :

1. my_dict = dict()

2. my_dict = {}

But out of these two options {} is more efficient than dict() plus its readable. CHECK HERE

Using c-promise2 lib the cancellable fetch with timeout might look like this one (Live jsfiddle demo):

import CPromise from "c-promise2"; // npm package

function fetchWithTimeout(url, {timeout, ...fetchOptions}= {}) {
    return new CPromise((resolve, reject, {signal}) => {
        fetch(url, {...fetchOptions, signal}).then(resolve, reject)
    }, timeout)
}
        
const chain = fetchWithTimeout("https://run.mocky.io/v3/753aa609-65ae-4109-8f83-9cfe365290f0?mocky-delay=10s", {timeout: 5000})
    .then(request=> console.log('done'));
    
// chain.cancel(); - to abort the request before the timeout

This code as a npm package cp-fetch

The method argument specifies the parameter of the smooth statistic. You can see stat_smooth for the list of all possible arguments to the method argument.

How about:

00 00  *  *   * every 3 days && echo test

Where every is a script:

#!/bin/sh

case $2 in
    days)
        expr `date +%j` % $1 = 0 > /dev/null
        ;;

    weeks)
        expr `date +%V` % $1 = 0 > /dev/null
        ;;

    months)
        expr `date +%m` % $1 = 0 > /dev/null
        ;;
esac

So it runs every day.

Using */3 runs on the 3rd, 6th, ... 27th, 30th of the month, but is then wrong after a month has a 31st day. The every script is only wrong after the end of the year.

I think that if your "item_manuf_id" is the primary key of the DataTable you could use the Find method ...

string s = "stringValue";
DataRow foundRow = dtPs.Rows.Find(s);
if(foundRow != null) {
 //You have it ...
 }

This worked for me (on Windows 10):

1. Add the following lines into your scripts in the package.json file:

   "dev": "npm run development",
   "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
   "watch": "npm run development -- --watch",
   "watch-poll": "npm run watch -- --watch-poll",
   "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
   "prod": "npm run production",
   "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
   

2. Make your devDependencies looks something like this:

   "devDependencies": {
       "axios": "^0.18",
       "bootstrap": "^4.0.0",
       "popper.js": "^1.12",
       "cross-env": "^5.1",
       "jquery": "^3.2",
       "laravel-mix": "^2.0",
       "lodash": "^4.17.4",
       "vue": "^2.5.7"
   }
   

3. Remove node_modules folder

4. Run npm install
5. Run npm run dev

A couple of issues arise when trying to reload/source ~/.profile file. [This refers to Ubuntu linux - in some cases the details of the commands will be different]

1. Are you running this directly in terminal or in a script?
2. How do you run this in a script?

Ad. 1)

Running this directly in terminal means that there will be no subshell created. So you can use either two commands:

source ~/.bash_profile

or

. ~/.bash_profile

In both cases this will update the environment with the contents of .profile file.

Ad 2) You can start any bash script either by calling

sh myscript.sh 

or

. myscript.sh

In the first case this will create a subshell that will not affect the environment variables of your system and they will be visible only to the subshell process. After finishing the subshell command none of the exports etc. will not be applied. THIS IS A COMMON MISTAKE AND CAUSES A LOT OF DEVELOPERS TO LOSE A LOT OF TIME.

In order for your changes applied in your script to have effect for the global environment the script has to be run with

.myscript.sh

command.

In order to make sure that you script is not runned in a subshel you can use this function. (Again example is for Ubuntu shell)

#/bin/bash

preventSubshell(){
  if [[ $_ != $0 ]]
  then
    echo "Script is being sourced"
  else
    echo "Script is a subshell - please run the script by invoking . script.sh command";
    exit 1;
  fi
}

I hope this clears some of the common misunderstandings! :D Good Luck!

To add to the answers of Ryley and atonyc, you don't actually have to use a real CSS property, like text-index or border-spacing, but instead you can specify a fake CSS property, like rotation or my-awesome-property. It might be a good idea to use something that does not risk becoming an actual CSS property in the future.

Also, somebody asked how to animate other things at the same time. This can be done as usual, but remember that the step function is called for every animated property, so you'll have to check for your property, like so:

$('#foo').animate(
    {
        opacity: 0.5,
        width: "100px",
        height: "100px",
        myRotationProperty: 45
    },
    {
        step: function(now, tween) {
            if (tween.prop === "myRotationProperty") {
                $(this).css('-webkit-transform','rotate('+now+'deg)');
                $(this).css('-moz-transform','rotate('+now+'deg)'); 
                // add Opera, MS etc. variants
                $(this).css('transform','rotate('+now+'deg)');  
            }
        }
    });

(Note: I can't find the documentation for the "Tween" object in the jQuery documentation; from the animate documentation page there is a link to http://api.jquery.com/Types#Tween which is a section that doesn't appear to exist. You can find the code for the Tween prototype on Github here).

add the line to your .bashrc or .profile. The variables set in $HOME/.profile are active for the current user, the ones in /etc/profile are global. The .bashrc is pulled on each bash session start.

I resolved the same issue by adding this property to hdfs-site.xml

<property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:9000</value>
  </property>

Especially for parent divs with relative (unknown) height, the centering in the unknown solution works great for me. There are some really nice code examples in the article.

It was tested in Chrome, Firefox, Opera, and Internet Explorer.

/* This parent can be any width and height */_x000D_
.block {_x000D_
  text-align: center;_x000D_
}_x000D_
_x000D_
/* The ghost, nudged to maintain perfect centering */_x000D_
.block:before {_x000D_
  content: '';_x000D_
  display: inline-block;_x000D_
  height: 100%;_x000D_
  vertical-align: middle;_x000D_
  margin-right: -0.25em; /* Adjusts for spacing */_x000D_
}_x000D_
_x000D_
/* The element to be centered, can_x000D_
   also be of any width and height */ _x000D_
.centered {_x000D_
  display: inline-block;_x000D_
  vertical-align: middle;_x000D_
  width: 300px;_x000D_
}

<div style="width: 400px; height: 200px;">_x000D_
   <div class="block" style="height: 90%; width: 100%">_x000D_
  <div class="centered">_x000D_
  <h1>Some text</h1>_x000D_
  <p>Any other text..."</p>_x000D_
  </div> _x000D_
   </div>_x000D_
</div>

You can't use a function to insert data into a base table. Functions return data. This is listed as the very first limitation in the documentation:

User-defined functions cannot be used to perform actions that modify the database state.

"Modify the database state" includes changing any data in the database (though a table variable is an obvious exception the OP wouldn't have cared about 3 years ago - this table variable only lives for the duration of the function call and does not affect the underlying tables in any way).

You should be using a stored procedure, not a function.

I have made a script in ASP code to detect browser, browser version, OS and OS version. The reason for me to do this in ASP was because i want to store the data in a log-database. So I had to detect the browser serverside.

Here is the code:

'Use the variables here for whatever you need........

it seems as if it comes when u have an previous compiled version of your program running

It seems like it exists a bug in jQuery reported here : http://bugs.jquery.com/ticket/13183 that breaks the Fancybox script.

Also check https://github.com/fancyapps/fancyBox/issues/485 for further reference.

As a workaround, rollback to jQuery v1.8.3 while either the jQuery bug is fixed or Fancybox is patched.

UPDATE (Jan 16, 2013): Fancybox v2.1.4 has been released and now it works fine with jQuery v1.9.0.

For fancybox v1.3.4- you still need to rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.

UPDATE (Jan 17, 2013): Workaround for users of Fancybox v1.3.4 :

Patch the fancybox js file to make it work with jQuery v1.9.0 as follow :

1. Open the jquery.fancybox-1.3.4.js file (full version, not pack version) with a text/html editor.

2. Find around the line 29 where it says :

   isIE6 = $.browser.msie && $.browser.version < 7 && !window.XMLHttpRequest,
   

   and replace it by (EDITED March 19, 2013: more accurate filter):

   isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,
   

   UPDATE (March 19, 2013): Also replace $.browser.msie by navigator.userAgent.match(/msie [6]/i) around line 615 (and/or replace all $.browser.msie instances, if any), thanks joofow ... that's it!

Or download the already patched version from HERE (UPDATED March 19, 2013 ... thanks fairylee for pointing out the extra closing bracket)

NOTE: this is an unofficial patch and is unsupported by Fancybox's author, however it works as is. You may use it at your own risk ;)

Optionally, you may rather rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.

<%= link_to "http://www.facebook.com/sharer.php?u=" + article_url(article, :text => article.title), :class => "btn btn-primary" do %>   <i class="fa fa-facebook">     Facebook Share    </i> <%end%> 

I am assuming that current_article_url is http://0.0.0.0:4567/link_to_title

The quotes you use are the issue:

<meta http-equiv=”refresh” content=”5" >

You should use the "

<meta http-equiv="refresh" content="5">

Since everything is an expression, and thus results in a value, you can just use if/else.

a = if true then 5 else 10
a = if false then 5 else 10

You can see more about expression examples here.

Easiest way ever.

1. Catch a Breakpoint somewhere.

2. Enter po NSHomeDirectory() in console window

Result:

(lldb) po NSHomeDirectory() /Users/usernam/Library/Developer/CoreSimulator/Devices/4734F8C7-B90F-4566-8E89-5060505E387F/data/Containers/Data/Application/395818BB-6D0F-499F-AAFE-068A783D9753

What I do is take common tasks like centering or floating and make CSS classes out of them. When I do that I can use them throughout any of the pages. I can also call as many as I want on the same element.

.text_center {text-align: center;}
.center {margin: auto 0px;}
.float_left {float: left;}

Now I can use them in my HTML code to perform simple tasks.

<p class="text_center">Some Text</p>

When putting resource files in another location is not the best solution you can use:

<build>
  <resources>
    <resource>
      <directory>src/main/java</directory>
      <excludes>
        <exclude>**/*.java</exclude>
      </excludes>
    </resource>
  </resources>
<build>

For example when resources files (e.g. jaxb.properties) goes deep inside packages along with Java classes.

Press Ctrl+,

Then you will see a docked window under name of "Go to all"

This a picture of the "Go to all" in my IDE

If you want more than one style this is the correct full answer. This is div with class and style:

<div className="class-example" style={{width: '300px', height: '150px'}}></div>

C isn't as high-level as the scripting language you mention. But if you want to stay away from socket-based programming, try Curl. Curl is a great C library and has many features. I have used it for years and always recommend it. It also includes some stand alone programs for testing or shell use.

ng-bind has its problems too.When you try to use angular filters, limit or something else, you maybe can have problem if you use ng-bind. But in other case, ng-bind is better in UX side.when user opens a page, he/she will see (10ms-100ms) that print symbols ( {{ ... }} ), that's why ng-bind is better.

@QueryMap worked for me instead of FieldMap

If you have a bunch of GET params, another way to pass them into your url is a HashMap.

class YourActivity extends Activity {

private static final String BASEPATH = "http://www.example.com";

private interface API {
    @GET("/thing")
    void getMyThing(@QueryMap Map<String, String> params, new Callback<String> callback);
}

public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.your_layout);

   RestAdapter rest = new RestAdapter.Builder().setEndpoint(BASEPATH).build();
   API service = rest.create(API.class);

   Map<String, String> params = new HashMap<String, String>();
   params.put("key1", "val1");
   params.put("key2", "val2");
   // ... as much as you need.

   service.getMyThing(params, new Callback<String>() {
       // ... do some stuff here.
   });
}
}

The URL called will be http://www.example.com/thing/?key1=val1&key2=val2

div.style.removeProperty('zoom');

As noted by CommonsWare in this question https://stackoverflow.com/a/16064418/1319061, this error can also occur if you are creating an anonymous subclass of a Fragment, since anonymous classes cannot have constructors.

Don't make anonymous subclasses of Fragment :-)

I would bind two different getters/setters pair to one variable:

class Coordinates{
    int red;

    @JsonProperty("red")
    public byte getRed() {
      return red;
    }

    public void setRed(byte red) {
      this.red = red;
    }

    @JsonProperty("r")
    public byte getR() {
      return red;
    }

    public void setR(byte red) {
      this.red = red;
    }
}

Most simple way (assumed you want to remove the element)

<span id='close' onclick='this.parentNode.parentNode.parentNode.removeChild(this.parentNode.parentNode); return false;'>x</span>

Add this inside your div, an example here.

You may also use something like this

window.onload = function(){
    document.getElementById('close').onclick = function(){
        this.parentNode.parentNode.parentNode
        .removeChild(this.parentNode.parentNode);
        return false;
    };
};

An Example Here.

Css for close button

#close {
    float:right;
    display:inline-block;
    padding:2px 5px;
    background:#ccc;
}

You may add a hover effect like

#close:hover {
    float:right;
    display:inline-block;
    padding:2px 5px;
    background:#ccc;
    color:#fff;
}

Something like this one.

Just did the test and it works with toEqual

please find my test:

http://jsfiddle.net/7q9N7/3/

describe('toEqual', function() {
    it('passes if arrays are equal', function() {
        var arr = [1, 2, 3];
        expect(arr).toEqual([1, 2, 3]);
    });
});

Just for information:

toBe() versus toEqual(): toEqual() checks equivalence. toBe(), on the other hand, makes sure that they're the exact same object.

Thanks Kip, for those who may be looking to achieve the same using $(this) whilst iterating or associating within a function:

$("label[for="+$(this).attr("id")+"]").addClass( "orienSel" );

I looked for a while whilst working this project but couldn't find a good example so I hope this helps others who may be looking to resolve the same issue.

In the example above, my objective was to hide the radio inputs and style the labels to provide a slicker user experience (changing the orientation of the flowchart).

You can see an example here

If you like the example, here is the css:

.orientation {      position: absolute; top: -9999px;   left: -9999px;}
    .orienlabel{background:#1a97d4 url('http://www.ifreight.solutions/process.html/images/icons/flowChart.png') no-repeat 2px 5px; background-size: 40px auto;color:#fff; width:50px;height:50px;display:inline-block; border-radius:50%;color:transparent;cursor:pointer;}
    .orR{   background-position: 9px -57px;}
    .orT{   background-position: 2px -120px;}
    .orB{   background-position: 6px -177px;}

    .orienSel {background-color:#323232;}

and the relevant part of the JavaScript:

function changeHandler() {
    $(".orienSel").removeClass( "orienSel" );
    if(this.checked) {
        $("label[for="+$(this).attr("id")+"]").addClass( "orienSel" );
    }
};

An alternate root to the original question, given the label follows the input, you could go with a pure css solution and avoid using JavaScript altogether...:

input[type=checkbox]:checked+label {}

Edit /var/lib/logrotate.status (or /var/lib/loglogrotate/logrotate.status) to reset the 'last rotated' date on the log file you want to test.

Then run logrotate YOUR_CONFIG_FILE.

Or you can use the --force flag, but editing logrotate.status gives you more precision over what does and doesn't get rotated.

Check this:

  let cloned = source.map(x => Object.assign({}, x));

It's really hard to tell, but one of the 9001 ads on the page may be clobbering the $ object.

jQuery provides the global jQuery object (which is present on your page). You can do the following to "get" $ back:

jQuery(document).ready(function ($) {
    // Your code here
});

If you think you're having jQuery problems, please use the debug (non-production) versions of the library.

Also, it's probably not best to be editing a live site like that ...

LINQ:

Enumerable.Range(0, 1 + end.Subtract(start).Days)
          .Select(offset => start.AddDays(offset))
          .ToArray(); 

For loop:

var dates = new List<DateTime>();

for (var dt = start; dt <= end; dt = dt.AddDays(1))
{
   dates.Add(dt);
}

EDIT: As for padding values with defaults in a time-series, you could enumerate all the dates in the full date-range, and pick the value for a date directly from the series if it exists, or the default otherwise. For example:

var paddedSeries = fullDates.ToDictionary(date => date, date => timeSeries.ContainsDate(date) 
                                               ? timeSeries[date] : defaultValue);

Also, you can copy an item from the finder using command-C, jump into the Terminal (e.g. using Spotlight or QuickSilver) type 'cd ' and simply paste with command-v

from __future__ import with_statement
with open('file.txt','r+') as f:
    counter = str(int(f.read().strip())+1)
    f.seek(0)
    f.write(counter)

Add the css styling text-align: center to the control.

Ideally you would do this through a css class assigned to the control, but if you must do it directly, here is an example:

<asp:TextBox ID="myTextBox" runat="server" style="text-align: center"></asp:TextBox>

There may simply not be such a guide. If so, you may not have much luck convincing anybody to write one, because it would be a lot of work.

I would recommend either of two things. The easier one is to follow the guide you have slavishly, which means forgetting about msysgit.

The harder one is to put up a Linux server - perhaps as a guest under Windows using VirtualBox (free) or VMWare or Parallels (pay), and then follow one of the many sets of instructions Google will lead you to. But you will probably find those instructions are insufficient - they usually assume you've already set up an ssh server, for example, so you have to get that info elsewhere. I've done that twice, and can say that unless you're already something of a Linux guru, it will be a struggle.

you can use online library

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

or else download library and add css in css folder and jquery in js folder.both folder you keep in laravel public folder then you can link like below

<link rel="stylesheet" href="{{asset('css/bootstrap-theme.min.css')}}">
<script src="{{asset('js/jquery.min.js')}}"></script>

or else

{{ HTML::style('css/style.css') }}
{{ HTML::script('js/functions.js') }}

Sounds like we need to assume that your textbox name and ID are both set to "Tue." If that's the case, try using a lower-case V on .value.

There is an article available in which explains how to perform multiple deletion paths using triggers. Maybe this is useful for complex scenarios.

I too have been through this pain - if the query is dynamically generated (e.g. Hibernate Criteria) then I couldn't find a practical way to do it.

The good news for me was that I was only investigating union to solve a performance problem when using an 'or' in an Oracle database.

The solution Patrick posted (combining the results programmatically using a set) while ugly (especially since I wanted to do results paging as well) was adequate for me.

Since C++14 you can use two real string literals:

const string hello = "Hello"s;

const string message = hello + ",world"s + "!"s;

or

const string exclam = "!"s;

const string message = "Hello"s + ",world"s + exclam;

I just wanted something really basic to move some files out of the main folder, like user2889485's reply, but his specific answer didnt work for me. I didnt care if they were in the same package or not.

My GOPATH workspace is c:\work\go and under that I have

/src/pg/main.go      (package main)
/src/pg/dbtypes.go   (pakage dbtypes)

in main.go I import "/pg/dbtypes"

"The OPN [Debug] target overrides the OTHER_LDFLAGS build setting". This was the main issue. After adding $(inherited) in new line in other linker flags solved my issue.

If you use auto-layout.

button.titleLabel?.adjustsFontSizeToFitWidth = true
button.titleLabel?.numberOfLines = 2

IOError: [Errno 13] Permission denied: 'juliodantas2015.json'

tells you everything you need to know: though you successfully made your python program executable with your chmod, python can't open that juliodantas2015.json' file for writing. You probably don't have the rights to create new files in the folder you're currently in.

I think you can always try the Ctrl + Shift + A to find the action/command you need.
Here you can try to press Ctrl + Shift + A and input «test» to find the command.

Prevent Activity to recreated Most common solution to dealing with orientation changes by setting the android:configChanges flag on your Activity in AndroidManifest.xml. Using this attribute your Activities won’t be recreated and all your views and data will still be there after orientation change.

<activity
    android:name="com.example.test.activity.MainActivity"
    android:configChanges="orientation|screenSize|keyboardHidden"/>

this is work for me

Depending on your needs, you may also want to check out the classes CountDownLatch and CyclicBarrier in the java.util.concurrent package. They can be useful if you want your threads to wait for each other, or if you want more fine-grained control over the way your threads execute (e.g., waiting in their internal execution for another thread to set some state). You could also use a CountDownLatch to signal all of your threads to start at the same time, instead of starting them one by one as you iterate through your loop. The standard API docs have an example of this, plus using another CountDownLatch to wait for all threads to complete their execution.

When converting an ASP.Net webform prototype to a MVC site I got these errors:

TypeError: $(...).accordion is not a function
$("#accordion").accordion(

$('#dialog').dialog({
TypeError: $(...).dialog is not a function

It worked fine in the webforms. The problem/solution was this line in the _Layout.cshtml

@Scripts.Render("~/bundles/jquery")

Comment it out to see if the errors go away. Then fix it in the BundlesConfig:

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));

Or you can try this:

(From p In context.Persons Select p Order By age Descending).FirstOrDefault

You can't set the field having data-type "text". Only because of that thing you are getting this error. Try to change the data-type with int

Two and a half years late is better than never, right?

int System.in.read() reads the next byte of data from the input stream. But I am sure you already knew that, because it is trivial to look up. So, what you are probably asking is:

• Why is it declared to return an int when the documentation says that it reads a byte?

• and why does it appear to return garbage? (I type '9', but it returns 57.)

It returns an int because besides all the possible values of a byte, it also needs to be able to return an extra value to indicate end-of-stream. So, it has to return a type which can express more values than a byte can.

^{Note: They could have made it a short, but they opted for int instead, possibly as a tip of the hat of historical significance to C, whose getc() function also returns an int, but more importantly because short is a bit cumbersome to work with, (the language offers no means of specifying a short literal, so you have to specify an int literal and cast it to short,) plus on certain architectures int has better performance than short.}

It appears to return garbage because when you view a character as an integer, what you are looking at is the ASCII^(*) value of that character. So, a '9' appears as a 57. But if you cast it to a character, you get '9', so all is well.

^{Think of it this way: if you typed the character '9' it is nonsensical to expect System.in.read() to return the number 9, because then what number would you expect it to return if you had typed an 'a'? Obviously, characters must be mapped to numbers. ASCII(*) is a system of mapping characters to numbers. And in this system, character '9' maps to number 57, not number 9.}

(*) Not necessarily ASCII; it may be some other encoding, like UTF-16; but in the vast majority of encodings, and certainly in all popular encodings, the first 127 values are the same as ASCII. And this includes all english alphanumeric characters and popular symbols.

You can try a simple kernel and the filter2D function, e.g. in Python:

kernel = np.array([[-1,-1,-1], [-1,9,-1], [-1,-1,-1]])
im = cv2.filter2D(im, -1, kernel)

Wikipedia has a good overview of kernels with some more examples here - https://en.wikipedia.org/wiki/Kernel_(image_processing)

In image processing, a kernel, convolution matrix, or mask is a small matrix. It is used for blurring, sharpening, embossing, edge detection, and more. This is accomplished by doing a convolution between a kernel and an image.

There are several possible answers here. You want to return something that might exist. Here are some options, ranging from my least preferred to most preferred:

• Return by reference, and signal can-not-find by exception.

  Attr& getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return attributes[i];
     //if not found
          throw no_such_attribute_error;
  }

It's likely that not finding attributes is a normal part of execution, and hence not very exceptional. The handling for this would be noisy. A null value cannot be returned because it's undefined behaviour to have null references.

• Return by pointer

  Attr* getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return &attributes[i];
     //if not found
          return nullptr;
  }

It's easy to forget to check whether a result from getAttribute would be a non-NULL pointer, and is an easy source of bugs.

• Use Boost.Optional

  boost::optional<Attr&> getAttribute(const string& attribute_name) const 
  {
     //search collection
     //if found at i
          return attributes[i];
     //if not found
          return boost::optional<Attr&>();
  }

A boost::optional signifies exactly what is going on here, and has easy methods for inspecting whether such an attribute was found.

Side note: std::optional was recently voted into C++17, so this will be a "standard" thing in the near future.

Option(getObject) foreach (QueueManager add)

I am using MariaDB and have the similar problem.

From MariaDB site, it is recommended to fix it by

1. Switch to using the mysqlnd driver in PHP (Recommended solution).

2. Run with a lower error reporting level:

   $err_level = error_reporting(0);  
   $conn = mysql_connect('params');  
   error_reporting($err_level); 
   

3. Recompile PHP with the MariaDB client libraries.
4. Use your original MySQL client library with the MariaDB.

My problem fixed by using the mysqlnd driver in Ubuntu:

sudo apt-get install php5-mysqlnd

Cheers!

[update: extra information] Installing this driver also resolve PDO problem that returns integer value as a string. To keep the type as integer, after installing mysqlInd, do this

$db = new PDO('mysql:host='.$host.';dbname='.$db_name, $user, $pass, 
          array( PDO::ATTR_PERSISTENT => true));
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$db->setAttribute(PDO::ATTR_STRINGIFY_FETCHES, false);

The Path is the only thing you really have to worry about if you are really new to Java. You need to drag your image into the main project file, and it will show up at the very bottom of the list.

Then the file path is pretty straight forward. This code goes into the constructor for the class.

    img = Toolkit.getDefaultToolkit().createImage("/home/ben/workspace/CS2/Background.jpg");

CS2 is the name of my project, and everything before that is leading to the workspace.

FYI...if you use TortoiseSVN and you want to create a simple batch file to xcopy (or directory mirror) entire repositories into a "safe" location on a periodic basis, then this is the specific code that you might want to use. It copies over the hidden directories/files, maintains read-only attributes, and all subdirectories and best of all, doesn't prompt for input. Just make sure that you assign folder1 (safe repo) and folder2 (usable repo) correctly.

@echo off
echo "Setting variables..."
set folder1="Z:\Path\To\Backup\Repo\Directory"
set folder2="\\Path\To\Usable\Repo\Directory"
echo "Removing sandbox version..."
IF EXIST %folder1% (
    rmdir %folder1% /s /q
)
echo "Copying official repository into backup location..."
xcopy /e /i /v /h /k %folder2% %folder1%

And, that's it folks!

Add to your scheduled tasks and never look back.

I like assylias' answer, however I would refactor it as follows:

Sub test()

Dim origNum As String
Dim creditOrDebit As String

origNum = "30062600006"
creditOrDebit = "D"

If creditOrDebit = "D" Then
  If origNum = "006260006" Then
    MsgBox "OK"
  ElseIf origNum = "30062600006" Then
    MsgBox "OK"
  End If
End If

End Sub

This might save you some CPU cycles since if creditOrDebit is <> "D" there is no point in checking the value of origNum.

Update:

I used the following procedure to test my theory that my procedure is faster:

Public Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub DoTests2()

  Dim startTime1 As Long
  Dim endTime1 As Long
  Dim startTime2 As Long
  Dim endTime2 As Long
  Dim i As Long
  Dim msg As String

  Const numberOfLoops As Long = 10000
  Const origNum As String = "006260006"
  Const creditOrDebit As String = "D"

  startTime1 = timeGetTime
  For i = 1 To numberOfLoops
    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        ' do something here
        Debug.Print "OK"
      ElseIf origNum = "30062600006" Then
        ' do something here
        Debug.Print "OK"
      End If
    End If
  Next i
  endTime1 = timeGetTime

  startTime2 = timeGetTime
  For i = 1 To numberOfLoops
    If (origNum = "006260006" Or origNum = "30062600006") And _
      creditOrDebit = "D" Then
      ' do something here
      Debug.Print "OK"
    End If
  Next i
  endTime2 = timeGetTime

  msg = "number of iterations: " & numberOfLoops & vbNewLine
  msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
       " ms" & vbNewLine
  msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
       " ms"

  MsgBox msg

End Sub

I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)

After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit is <>"D", my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.

And that is why I refactored it - to short-circuit the logic so that origNum doesn't need to be evaluated when creditOrDebit <> "D".

At this point, the rest depends on the OP's spreadsheet. If creditOrDebit is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit has a wide range of possible values, and D is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.

First off, Xvfb doesn't read configuration from xorg.conf. Xvfb is a variant of the KDrive X servers and like all members of that family gets its configuration from the command line.

It is true that XRandR and Xinerama are mutually exclusive, but in the case of Xvfb there's no Xinerama in the first place. You can enable the XRandR extension by starting Xvfb using at least the following command line options

Xvfb +extension RANDR [further options]

After looking more, the root element has to be associated with a schema-namespace as Blaise is noting. Yet, I didnt have a package-info java. So without using the @XMLSchema annotation, I was able to correct this issue by using

@XmlRootElement (name="RetrieveMultipleSetsResponse", namespace = XMLCodeTable.NS1)
@XmlType(name = "ns0", namespace = XMLCodeTable.NS1)
@XmlAccessorType(XmlAccessType.NONE)
public class RetrieveMultipleSetsResponse {//...}

Hope this helps!

Update for .NET 4.5.1

Now that .NET 4.5.1 is available the actual value of the key named Release in the registry needs to be checked, not just its existence. A value of 378758 means that .NET Framework 4.5.1 is installed. However, as described here this value is 378675 on Windows 8.1.

You should use html():

SEE DEMO

$(document).ready(function(){
    $("#date").html('<span>'+$("#date").text().substring(0, 2) + '</span><br />'+$("#date").text().substring(3));     
});

I've added to /etc/sysconfig/jenkins (CentOS):

# Options to pass to java when running Jenkins.
#
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Xmx1024m -XX:MaxPermSize=512m"

For ubuntu the same config should be located in /etc/default

use this code for set value in input tag by another id.

$(".formdata").val(document.getElementById("fsd").innerHTML);

or use this code for set value in input tag using classname="formdata"

$(".formdata").val("hello");

I don't know the answer for XP, but for latter:

%USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low and %USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5 - these are cache locations. Other mentioned %USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files but this not a cache in this directory there are just a reflection of files that are stored somewhere else.

But you can enum %USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files and get all files you need, but you should be frustrated that file walker do not detect everything that explorer shows.

Also if you use links I gave you may need ExpandEnvironmentStrings from WinAPI.

to ckeck the status use the below command, which worked on debian....

/etc/init.d/mysql status

to start my sql server use the below command

/etc/init.d/mysql start

to stop the server use the below command

/etc/init.d/mysql stop

For Web API 2 my methods consistently return IHttpActionResult so I use...

public IHttpActionResult Save(MyEntity entity)
{
  ....

    return ResponseMessage(
        Request.CreateResponse(
            HttpStatusCode.BadRequest, 
            validationErrors));
}

This is by far the best SQLite library that I've used in Swift: https://github.com/stephencelis/SQLite.swift

Look at the code examples. So much cleaner than the C API:

import SQLite

let db = try Connection("path/to/db.sqlite3")

let users = Table("users")
let id = Expression<Int64>("id")
let name = Expression<String?>("name")
let email = Expression<String>("email")

try db.run(users.create { t in
    t.column(id, primaryKey: true)
    t.column(name)
    t.column(email, unique: true)
})
// CREATE TABLE "users" (
//     "id" INTEGER PRIMARY KEY NOT NULL,
//     "name" TEXT,
//     "email" TEXT NOT NULL UNIQUE
// )

let insert = users.insert(name <- "Alice", email <- "[email protected]")
let rowid = try db.run(insert)
// INSERT INTO "users" ("name", "email") VALUES ('Alice', '[email protected]')

for user in try db.prepare(users) {
    print("id: \(user[id]), name: \(user[name]), email: \(user[email])")
    // id: 1, name: Optional("Alice"), email: [email protected]
}
// SELECT * FROM "users"

let alice = users.filter(id == rowid)

try db.run(alice.update(email <- email.replace("mac.com", with: "me.com")))
// UPDATE "users" SET "email" = replace("email", 'mac.com', 'me.com')
// WHERE ("id" = 1)

try db.run(alice.delete())
// DELETE FROM "users" WHERE ("id" = 1)

try db.scalar(users.count) // 0
// SELECT count(*) FROM "users"

The documentation also says that "SQLite.swift also works as a lightweight, Swift-friendly wrapper over the C API," and follows with some examples of that.

Unwind segues are used to "go back" to some view controller from which, through a number of segues, you got to the "current" view controller.

Imagine you have something a MyNavController with A as its root view controller. Now you use a push segue to B. Now the navigation controller has A and B in its viewControllers array, and B is visible. Now you present C modally.

With unwind segues, you could now unwind "back" from C to B (i.e. dismissing the modally presented view controller), basically "undoing" the modal segue. You could even unwind all the way back to the root view controller A, undoing both the modal segue and the push segue.

Unwind segues make it easy to backtrack. For example, before iOS 6, the best practice for dismissing presented view controllers was to set the presenting view controller as the presented view controller’s delegate, then call your custom delegate method, which then dismisses the presentedViewController. Sound cumbersome and complicated? It was. That’s why unwind segues are nice.

This is not only a 'newbie' scenario. I just ran across this compiler message (GCC 5.4) when refactoring a class to remove some constructor parameters. I forgot to update both the declaration and definition, and the compiler spit out this unintuitive error.

The bottom line seems to be this: If the compiler can't match the definition's signature to the declaration's signature it thinks the definition is not a constructor and then doesn't know how to parse the code and displays this error. Which is also what happened for the OP: std::string is not the same type as string so the declaration's signature differed from the definition's and this message was spit out.

As a side note, it would be nice if the compiler looked for almost-matching constructor signatures and upon finding one suggested that the parameters didn't match rather than giving this message.

I found very nice solution. Microsoft released a beta version of Entity Framework Power Tools: Entity Framework Power Tools Beta 2

There you can generate POCO classes, derived DbContext and Code First mapping for an existing database in some clicks. It is very nice!

After installation some context menu options would be added to your Visual Studio.

Right-click on a C# project. Choose Entity Framework-> Reverse Engineer Code First (Generates POCO classes, derived DbContext and Code First mapping for an existing database):

Then choose your database and click OK. That's all! It is very easy.

If you are using Eclipse, for an existing project (which has a build.gradle file) you can simply type gradle eclipse which will create all the Eclipse files and folders for this project.

It takes care of all the dependencies for you and adds them to the project resource path in Eclipse as well.

For those doing video I cobbled the following based on @tsh :

import cv2 as cv
import numpy as np

def nothing(x):pass

cap = cv.VideoCapture(0)
cv.namedWindow('videoUI', cv.WINDOW_NORMAL)
cv.createTrackbar('T','videoUI',0,255,nothing)

while(True):
    ret, frame = cap.read()
    vid_gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY)
    thresh = cv.getTrackbarPos('T','videoUI');
    vid_bw = cv.threshold(vid_gray, thresh, 255, cv.THRESH_BINARY)[1]

    cv.imshow('videoUI',cv.flip(vid_bw,1))

    if cv.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv.destroyAllWindows()

Results in:

If you have anything in particular you want to hide (like a proprietary algorithm), put that on the server, or put it in a Flash movie and call it with JavaScript. Writing ActionScript is very similar to writing JavaScript, and you can communicate between JavaScript and ActionScript. You can do the same with Silverlight, but Silverlight doesn't have the penetration Flash does.

However, remember that any mobile phones can run your JavaScript, but not Silverlight or Flash, so you're crippling your mobile users if you go with Flash or Silverlight.

The correct answer is

Options -Indexes

You must have been thinking of

AllowOverride All

https://httpd.apache.org/docs/2.2/howto/htaccess.html

.htaccess files (or "distributed configuration files") provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

This is JQuery behavior. I'm not sure why it works this way, it only triggers the onClick function on the link.

Try:

jQuery(document).ready(function() {
    jQuery('#foo').on('click', function() {
        jQuery('#bar')[0].click();
    });
});

I just reloaded, clean and rebuilt works for me.

Use count(d.ertek) or count(d.id) instead of count(d). This can be happen when you have composite primary key at your entity.

Actually, the problem is that either /sys/kernel/debug is not mounted, or that the running kernel has no ftrace tracers compiled in so that /sys/kernel/debug/tracing is unavailable. This is the code throwing the error (platform_frameworks_native/libs/utils/Trace.cpp):

void Tracer::init() {
    Mutex::Autolock lock(sMutex);

    if (!sIsReady) {
        add_sysprop_change_callback(changeCallback, 0);

        const char* const traceFileName =
                "/sys/kernel/debug/tracing/trace_marker";
        sTraceFD = open(traceFileName, O_WRONLY);
        if (sTraceFD == -1) {
            ALOGE("error opening trace file: %s (%d)", strerror(errno), errno);
            sEnabledTags = 0;   // no tracing can occur
        } else {
            loadSystemProperty();
        }

        android_atomic_release_store(1, &sIsReady);
    }
}

The log message could definitely be a bit more informative.

I Found this the most useful and easy to use https://wiki.python.org/moin/ConfigParserExamples

You can use explode also

Erik Allik already gave very good reasons, why you will most likely not want to collect elements of a stream into an existing List.

Anyway, you can use the following one-liner, if you really need this functionality.

But as Stuart Marks explains in his answer, you should never do this, if the streams might be parallel streams - use at your own risk...

list.stream().collect(Collectors.toCollection(() -> myExistingList));

You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.

There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).

Scope in python follows this order:

• Search the local scope

• Search the scope of any enclosing functions

• Search the global scope

• Search the built-ins

(source)

Notice that if and other looping/branching constructs are not listed - only classes, functions, and modules provide scope in Python, so anything declared in an if block has the same scope as anything decleared outside the block. Variables aren't checked at compile time, which is why other languages throw an exception. In python, so long as the variable exists at the time you require it, no exception will be thrown.

Yes, you can.

@supports (-webkit-touch-callout: none) {
  /* CSS specific to iOS devices */ 
}

@supports not (-webkit-touch-callout: none) {
  /* CSS for other than iOS devices */ 
}

YMMV.

It works because only Safari Mobile implements -webkit-touch-callout: https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-touch-callout

Please note that @supports does not work in IE. IE will skip both of the above @support blocks above. To find out more see https://hacks.mozilla.org/2016/08/using-feature-queries-in-css/. It is recommended to not use @supports not because of this.

What about Chrome or Firefox on iOS? The reality is these are just skins over the WebKit rendering engine. Hence the above works everywhere on iOS as long as iOS policy does not change. See 2.5.6 in App Store Review Guidelines.

Warning: iOS may remove support for this in any new iOS release in the coming years. You SHOULD try a bit harder to not need the above CSS. An earlier version of this answer used -webkit-overflow-scrolling but a new iOS version removed it. As a commenter pointed out, there are other options to choose from: Go to Supported CSS Properties and search for "Safari on iOS".

I have used facebook sdk 4.10.0 to integrate login in my android app. Tutorial I followed is :

facebook login android studio

You will be able to get first name, last name, email, gender , facebook id and birth date from facebbok.

Above tutorial also explains how to create app in facebook developer console through video.

add below in build.gradle(Module:app) file:

repositories {
        mavenCentral()
    }

and

 compile 'com.facebook.android:facebook-android-sdk:4.10.0'

now add below in AndroidManifest.xml file :

 <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="your app id from facebook developer console"/>

     <activity android:name="com.facebook.FacebookActivity"
               android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
               android:theme="@android:style/Theme.Translucent.NoTitleBar"
               android:label="@string/app_name" />

add following in activity_main.xml file :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.demonuts.fblogin.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#000"
        android:layout_marginLeft="10dp"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:id="@+id/text"/>

    <com.facebook.login.widget.LoginButton
        android:id="@+id/btnfb"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

The GNU site suggests this nice awk script, which prints both the words and their frequency.

Possible changes:

• You can pipe through sort -nr (and reverse word and freq[word]) to see the result in descending order.
• If you want a specific column, you can omit the for loop and simply write freq[3]++ - replace 3 with the column number.

Here goes:

 # wordfreq.awk --- print list of word frequencies

 {
     $0 = tolower($0)    # remove case distinctions
     # remove punctuation
     gsub(/[^[:alnum:]_[:blank:]]/, "", $0)
     for (i = 1; i <= NF; i++)
         freq[$i]++
 }

 END {
     for (word in freq)
         printf "%s\t%d\n", word, freq[word]
 }

is is generally preferred when comparing arbitrary objects to singletons like None because it is faster and more predictable. is always compares by object identity, whereas what == will do depends on the exact type of the operands and even on their ordering.

This recommendation is supported by PEP 8, which explicitly states that "comparisons to singletons like None should always be done with is or is not, never the equality operators."

here is a jsfiddle with an example of showing/hiding div's via a select.

HTML:

<div id="option1" class="group">asdf</div>
<div id="option2" class="group">kljh</div>
<div id="option3" class="group">zxcv</div>
<div id="option4" class="group">qwerty</div>
<select id="selectMe">
  <option value="option1">option1</option>
  <option value="option2">option2</option>
  <option value="option3">option3</option>
  <option value="option4">option4</option>
</select>

jQuery:

$(document).ready(function () {
  $('.group').hide();
  $('#option1').show();
  $('#selectMe').change(function () {
    $('.group').hide();
    $('#'+$(this).val()).show();
  })
});

Install 'spread_sheet' node module,it will both add and fetch row from local spreadsheet

If the above solution didn't work and you got any unhandled promise rejection then try to follow steps :

1. Clean the Cordova project

   cordova clean

   2. Remove platform

cordova platform remove android/ios

3. Then remove plugin

cordova plugin remove

4. add platforms and run the project It worked for me.

A dangling pointer points to memory that has already been freed. The storage is no longer allocated. Trying to access it might cause a Segmentation fault.

Common way to end up with a dangling pointer:

char *func()
{
   char str[10];
   strcpy(str, "Hello!");
   return str; 
}
//returned pointer points to str which has gone out of scope. 

You are returning an address which was a local variable, which would have gone out of scope by the time control was returned to the calling function. (Undefined behaviour)

Another common dangling pointer example is an access of a memory location via pointer, after free has been explicitly called on that memory.

int *c = malloc(sizeof(int));
free(c);
*c = 3; //writing to freed location!

A memory leak is memory which hasn't been freed, there is no way to access (or free it) now, as there are no ways to get to it anymore. (E.g. a pointer which was the only reference to a memory location dynamically allocated (and not freed) which points somewhere else now.)

void func(){
    char *ch = malloc(10);
}
//ch not valid outside, no way to access malloc-ed memory

Char-ptr ch is a local variable that goes out of scope at the end of the function, leaking the dynamically allocated 10 bytes.

I know this is a long cold question, but it comes up every time there is a new or recent major Java release. Now this would easily apply to 6 and 7 swapping.

I have done this in the past with update-java-alternatives: http://manpages.ubuntu.com/manpages/hardy/man8/update-java-alternatives.8.html

Since id is an attribute don't create an id element, just do this:

myPara.setAttribute("id", "id_you_like");

The simplest way to delete rows and columns from arrays is the numpy.delete method.

Suppose I have the following array x:

x = array([[1,2,3],
        [4,5,6],
        [7,8,9]])

To delete the first row, do this:

x = numpy.delete(x, (0), axis=0)

To delete the third column, do this:

x = numpy.delete(x,(2), axis=1)

So you could find the indices of the rows which have a 0 in them, put them in a list or a tuple and pass this as the second argument of the function.

I think you've just made up shorthand syntax for the border: property there =)

Try simply:

border-right: 1px solid #000;
border-left: 1px solid #000;

I resolve my problem doing this. [IMPORTANT NOTE: It allows escalated (expanded) privileges to the particular account, possibly more than are needed for individual scenario].

1. Go to 'Object Explorer' of SQL Management Studio.
2. Expand Security, then Login.
3. Select the user you are working with, then right click and select Properties Windows.
4. In Select a Page, Go to Server Roles
5. Click on sysadmin and save.

The task is fairly simple as the base filename is just the part of the string starting at the last delimeter for folders:

std::string base_filename = path.substr(path.find_last_of("/\\") + 1)

If the extension is to be removed as well the only thing to do is find the last . and take a substr to this point

std::string::size_type const p(base_filename.find_last_of('.'));
std::string file_without_extension = base_filename.substr(0, p);

Perhaps there should be a check to cope with files solely consisting of extensions (ie .bashrc...)

If you split this up into seperate functions you're flexible to reuse the single tasks:

template<class T>
T base_name(T const & path, T const & delims = "/\\")
{
  return path.substr(path.find_last_of(delims) + 1);
}
template<class T>
T remove_extension(T const & filename)
{
  typename T::size_type const p(filename.find_last_of('.'));
  return p > 0 && p != T::npos ? filename.substr(0, p) : filename;
}

The code is templated to be able to use it with different std::basic_string instances (i.e. std::string & std::wstring...)

The downside of the templation is the requirement to specify the template parameter if a const char * is passed to the functions.

So you could either:

A) Use only std::string instead of templating the code

std::string base_name(std::string const & path)
{
  return path.substr(path.find_last_of("/\\") + 1);
}

B) Provide wrapping function using std::string (as intermediates which will likely be inlined / optimized away)

inline std::string string_base_name(std::string const & path)
{
  return base_name(path);
}

C) Specify the template parameter when calling with const char *.

std::string base = base_name<std::string>("some/path/file.ext");

Result

std::string filepath = "C:\\MyDirectory\\MyFile.bat";
std::cout << remove_extension(base_name(filepath)) << std::endl;

Prints

MyFile

The Content-Length entity-header field indicates the size of the entity-body, in decimal number of OCTETs, sent to the recipient or, in the case of the HEAD method, the size of the entity-body that would have been sent had the request been a GET.

It doesn't matter what the content-type is.

Linux Mint 20 Ulyana users need to change "ulyana" to "bionic" in

/etc/apt/sources.list.d/additional-repositories.list

like so:

deb [arch=amd64] https://download.docker.com/linux/ubuntu    bionic    stable

For your purpose, I'd prefer using position instead of floating:

http://jsfiddle.net/aas7w0tw/1/

Use a parent with relative position:

position: relative;

And children in absolute position:

position: absolute;

In bonus, you can better drive the dimensions of your components.

1. Connect to a server you want to store your DB
2. Right-click Database
3. Click Restore
4. Choose the Device radio button under the source section
5. Click Add.
6. Navigate to the path where your .bak file is stored, select it and click OK
7. Enter the destination of your DB
8. Enter the name by which you want to store your DB
9. Click OK

Done

On Windows: if you use %>% inside a %dopar% loop, you have to add a reference to load package dplyr (or magrittr, which dplyr loads).

Example:

plots <- foreach(myInput=iterators::iter(plotCount), .packages=c("RODBC", "dplyr")) %dopar%
{
    return(getPlot(myInput))
}

If you omit the .packages command, and use %do% instead to make it all run in a single process, then works fine. The reason is that it all runs in one process, so it doesn't need to specifically load new packages.

It's a formal way of specifying a correlation name for an entity so that you can address it easily in another part of the query.

ES2017: You can wrap the async code inside a function(say XHRPost) returning a promise( Async code inside the promise).

One option would be to set up a windows service and get that to call your scheduled task.

In winforms I've used Timers put don't think this would work well in ASP.NET

I will answer the question even though it has been a long time since it was thrown, just in case someone else get to it.

Tested on Android Studio ONLY (but I guess it could work for Eclipse as well) :

Check your build/source/r folder. In there, you should find some directories labelled under the name of your gradle build name (default : debug). Verify that the name of the package associated with R is the one you want.

I know this trick solves the problem of switching namespace, because Android Studio (or Gradle I don't know who is responsible for that) seems not to regenerate it in that case.

I haven't tried it when importing a project from Eclipse though.

var list = arr.Select(i => Int32.Parse(i));

You can checking if emails is valid or no by using this libreries, and of course you can add array for this folowing project.

import org.apache.commons.validator.routines.EmailValidator;

public class Email{
    public static void main(String[] args){
        EmailValidator email = EmailVlidator.getInstance();
        boolean val = email.isValid("[email protected]");
        System.out.println("Mail is: "+val);
        val = email.isValid("hans.riguer.hotmsil.com");
        System.out.print("Mail is: "+val");
    }
}

output :

Mail is: true

Mail is : false
