from http://www.vmware.com/products/player/faqs.html:

How does VMware Player compare to VMware Workstation? VMware Player enables you to quickly and easily create and run virtual machines. However, VMware Player lacks many powerful features, remote connections to vSphere, drag and drop upload to vSphere, multiple Snapshots and Clones, and much more.

Not being able to revert snapshots it's a big no for me.

For razor you can use: culture, value

@String.Format(new CultureInfo("sv-SE"), @Model.value)

You can use %%~nf to get the filename only as described in the reference for for:

@echo off
    for /R "C:\Users\Admin\Ordner" %%f in (*.flv) do (
    echo %%~nf
)
pause

The following options are available:

Variable with modifier  Description

%~I                     Expands %I which removes any surrounding 
                        quotation marks ("").
%~fI                    Expands %I to a fully qualified path name.
%~dI                    Expands %I to a drive letter only.
%~pI                    Expands %I to a path only.
%~nI                    Expands %I to a file name only.
%~xI                    Expands %I to a file extension only.
%~sI                    Expands path to contain short names only.
%~aI                    Expands %I to the file attributes of file.
%~tI                    Expands %I to the date and time of file.
%~zI                    Expands %I to the size of file.
%~$PATH:I               Searches the directories listed in the PATH environment 
                        variable and expands %I to the fully qualified name of 
                        the first one found. If the environment variable name is 
                        not defined or the file is not found by the search,
                        this modifier expands to the empty string.    

We can do that with two way:
1- First create a new object and replicate the structure of the existing one by iterating 
 over its properties and copying them on the primitive level.

let user = {
     name: "John",
     age: 30
    };

    let clone = {}; // the new empty object

    // let's copy all user properties into it
    for (let key in user) {
      clone[key] = user[key];
    }

    // now clone is a fully independant clone
    clone.name = "Pete"; // changed the data in it

    alert( user.name ); // still John in the original object

2- Second we can use the method Object.assign for that 
    let user = { name: "John" };
    let permissions1 = { canView: true };
    let permissions2 = { canEdit: true };

    // copies all properties from permissions1 and permissions2 into user
    Object.assign(user, permissions1, permissions2);

  -Another example

    let user = {
      name: "John",
      age: 30
    };

    let clone = Object.assign({}, user);
It copies all properties of user into the empty object and returns it. Actually, the same as the loop, but shorter.

But Object.assign() not create a deep clone

let user = {
  name: "John",
  sizes: {
    height: 182,
    width: 50
  }
};

let clone = Object.assign({}, user);

alert( user.sizes === clone.sizes ); // true, same object

// user and clone share sizes
user.sizes.width++;       // change a property from one place
alert(clone.sizes.width); // 51, see the result from the other one

To fix that, we should use the cloning loop that examines each value of user[key] and, if it’s an object, then replicate its structure as well. That is called a “deep cloning”.

There’s a standard algorithm for deep cloning that handles the case above and more complex cases, called the Structured cloning algorithm. In order not to reinvent the wheel, we can use a working implementation of it from the JavaScript library lodash the method is called _.cloneDeep(obj).

You can use this simple method

function reloadFrame(iFrame) {

    iFrame.parentNode.replaceChild(iFrame.cloneNode(), iFrame);

}

There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal or you can just pump up number of lines that you want to have in history in the same place.

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

To set flashdata you need to redirect controller function

$this->session->set_flashdata('message_name', 'This is test message');

//redirect to some function
redirect("controller/function_name");

//echo in view or controller
$this->session->flashdata('message_name');

How about this one ? Simple and straightforward.

def is_list_sorted(al):

    llength =len(al)


    for i in range (llength):
        if (al[i-1] > al[i]):
            print(al[i])
            print(al[i+1])
            print('Not sorted')
            return -1

    else :
        print('sorted')
        return  true

I agree with Justin, and the WhiteSpace CHAR can be referenced using ASCII codes here Character number 32 represents a white space, Therefore:

string.Empty.PadRight(totalLength, (char)32);

An alternative approach: Create all spaces manually within a custom method and call it:

private static string GetSpaces(int totalLength)
    {
        string result = string.Empty;
        for (int i = 0; i < totalLength; i++)
        {
            result += " ";
        }
        return result;
    }

And call it in your code to create white spaces: GetSpaces(14);

Authentication is the process of verifying the proclaimed identity.

• e.g. username/password

Usually followed by authorization, which is the approval that you can do this and that.

• e.g. permissions

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.

A credit card number is not a bunch of random numbers. There is a formula for checking if it is correct.

After a quick Google search I found this JavaScript which will check a credit card number to be valid.

    Basically, the algorithm takes each digit, from right to left and muliplies each second
    digit by two. If the multiple is two-digits long (i.e.: 6 * 2 = 12) the two digits of
    the multiple are then added together for a new number (1 + 2 = 3). You then add up the
    string of numbers, both unaltered and new values and get a total sum. This sum is then
    divided by 10 and the remainder should be zero if it is a valid credit card. Hense the
    name Mod 10 or Modulus 10.

it clears stdin buffer before reading. From the man page:

For output streams, fflush() forces a write of all user-space buffered data for the given output or update stream via the stream's underlying write function. For input streams, fflush() discards any buffered data that has been fetched from the underlying file, but has not been consumed by the application.

Note: This is Linux-specific, using fflush() on input streams is undefined by the standard, however, most implementations behave the same as in Linux.

If you have problems with accessing to the path, maybe you need to put this:

$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/cv/"; 

// Open the folder
 $dir_handle = @opendir($root . $path) or die("Unable to open $path");

If you are using PHP version 5.3 or higher you can do the following:

$host= gethostname();
$ip = gethostbyname($host);

This works well when you are running a stand-alone script, not running through the web server.

This is an old question, anyway today the best practice is by using Object.defineProperty

const object1 = {};

Object.defineProperty(object1, 'property1', {
  value: 42,
  writable: false
});

object1.property1 = 77;
// throws an error in strict mode

console.log(object1.property1);
// expected output: 42

The org.apache.commons.text.StringSubstitutor helper class from Apache Commons Text provides named variable substitution

Map<String, String> valuesMap = new HashMap<>();
valuesMap.put("animal", "quick brown fox");
valuesMap.put("target", "lazy dog");
String resolved = new StringSubstitutor(valuesMap).replace("The ${animal} jumped over the ${target}.");
System.out.println(resolved); // The quick brown fox jumped over the lazy dog.

In our codebase; we typically declare enums in the class that they belong to.

So for your Fruit example, We would have a Fruit class, and inside that an Enum called Fruits.

Referencing it in the code looks like this: Fruit.Fruits.Apple, Fruit.Fruits.Pear, etc.

Constants follow along the same line, where they either get defined in the class to which they're relevant (so something like Fruit.ORANGE_BUSHEL_SIZE); or if they apply system-wide (i.e. an equivalent "null value" for ints) in a class named "ConstantManager" (or equivalent; like ConstantManager.NULL_INT). (side note; all our constants are in upper case)

As always, your coding standards probably differ from mine; so YMMV.

tl;dr

Can you make and edit a collection of objects from an enum? Yes.

If you do not care about the order, use EnumSet, an implementation of Set.

enum Animal{ DOG , CAT , BIRD , BAT ; }

Set<Animal> flyingAnimals = EnumSet.of( BIRD , BAT );

Set<Animal> featheredFlyingAnimals = flyingAnimals.clone().remove( BAT ) ;

If you care about order, use a List implementation such as ArrayList. For example, we can create a list of a person’s preference in choosing a pet, in the order of their most preferred.

List< Animal > favoritePets = new ArrayList<>() ;
favoritePets.add( CAT ) ;  // This person prefers cats over dogs…
favoritePets.add( DOG ) ;  // …but would accept either.
                           // This person would not accept a bird nor a bat.

For a non-modifiable ordered list, use List.of.

List< Animal > favoritePets = List.of( CAT , DOG ) ;  // This person prefers cats over dogs, but would accept either. This person would not accept a bird nor a bat. 

Details

The Answer (EnumSet) by Amit Deshpande and the Answer (.values) by Marko Topolnik are both correct. Here is a bit more info.

Enum.values

The .values() method is an implicitly declared method on Enum, added by the compiler. It produces a crude array rather than a Collection. Certainly usable.

Special note about documentation: Being unusual as an implicitly declared method, the .values() method is not listed among the methods on the Enum class. The method is defined in the Java Language Specification, and is mentioned in the doc for Enum.valueOf.

EnumSet – Fast & Small

The upsides to EnumSet include:

• Extreme speed.
• Compact use of memory.

To quote the class doc:

Enum sets are represented internally as bit vectors. This representation is extremely compact and efficient. The space and time performance of this class should be good enough to allow its use as a high-quality, typesafe alternative to traditional int-based "bit flags." Even bulk operations (such as containsAll and retainAll) should run very quickly if their argument is also an enum set.

Given this enum:

enum Animal
{
    DOG , CAT , BIRD , BAT ;
}

Make an EnumSet in one line.

Set<Animal> allAnimals = EnumSet.allOf( Animal.class );

Dump to console.

System.out.println( "allAnimals : " + allAnimals );

allAnimals : [DOG, CAT, BIRD, BAT]

Make a set from a subset of the enum objects.

Set<Animal> flyingAnimals = EnumSet.of( BIRD , BAT );

Look at the class doc to see many ways to manipulate the collection including adding or removing elements.

Set<Animal> featheredFlyingAnimals = 
    EnumSet.copyOf( flyingAnimals ).remove( BAT );

Natural Order

The doc promises the Iterator for EnumSet is in natural order, the order in which the values of the enum were originally declared.

To quote the class doc:

The iterator returned by the iterator method traverses the elements in their natural order (the order in which the enum constants are declared).

Frankly, given this promise, I'm confused why this is not a SortedSet. But, oh well, good enough. We can create a List from the Set if desired. Pass any Collection to constructor of ArrayList and that collection’s Iterator is automatically called on your behalf.

List<Animal> list = new ArrayList<>( allAnimals );

Dump to console.

System.out.println("list : " + list );

When run.

list : [DOG, CAT, BIRD, BAT]

In Java 10 and later, you can conveniently create a non-modifiable List by passing the EnumSet. The order of the new list will be in the iterator order of the EnumSet. The iterator order of an EnumSet is the order in which the element objects of the enum were defined on that enum.

List< Animal > nonModList = List.copyOf( allAnimals ) ;  // Or pass Animals.values() 

Investigate what is your EOL, \n or \r\n. Then replace .*#region.*\r\n with nothing in regexpr mode.

It's been more than 10 years and not sure if anyone still finding this question or answer relevant.

But a quick workaround is just to wrap the asp control within a html container

<div id="myElement" style="display: inline-block">
   <asp:TextBox ID="textBox1" runat="server"></asp:TextBox>
</div>

Whenever the Javascript Event is triggered, if it needs to be an event by the asp control, just wrap the asp control around the div container.

<div id="testG">  
   <asp:Button ID="Button2" runat="server" CssClass="btn" Text="Activate" />
</div>

The jQuery Code is below:

$(document).ready(function () {
    $("#testG").click(function () {
                $("#myElement").css("display", "none");
     });
});

You can use the u button to undo the last modification. (And Ctrl+R to redo it).

If you are still getting that error after installing the 64 bit JRE, it means that the JVM running Gurobi package is still using the 32 bit JRE.

Check that you have updated the PATH and JAVA_HOME globally and in the command shell that you are using. (Maybe you just need to exit and restart it.)

Check that your command shell runs the right version of Java by running "java -version" and checking that it says it is a 64bit JRE.

If you are launching the example via a wrapper script / batch file, make sure that the script is using the right JRE. Modify as required ...

Here is another solution (only relevant declarations listed):

.text span {
   display:inline-block;
   margin-right:100%;
}

When the margin is expressed in percentage, that percentage is taken from the width of the parent node, so 100% means as wide as the parent, which results in the next element getting "pushed" to a new line.

Thank you drifty0pine!

The first solution, it´s works!

[a relative link](../../some/dir/filename.md)
[Link to file in another dir on same drive](/another/dir/filename.md)
[Link to file in another dir on a different drive](/D:/dir/filename.md)

but I had need put more ../ until the folder where was my file, like this:

[FileToOpen](../../../../folderW/folderX/folderY/folderZ/FileToOpen.txt)

I just started yesterday on Windows 7 and was facing the same problem. The easiest solution, I found and is working for me is to use the low config device in the emulator. I used Nexus One instead of Nexus 7 and select the snapshot for the device in Android Virtual Device.

And, also important is to leave open the emulator. It works both in Eclipse and Android Studio.

In a window, it says snapshot does not generally work when RAM is more than ~700. So, selecting a lower configured one easily help to test Hello World and then for developing your application. Later, we can test on a high-end device.

For me, virtualization support does not work as my hardware does not support it.

@media (max-width: @iphone-screen) {
  background-attachment:inherit;    
  background-size:cover;
  -webkit-background-size:cover;
}

override func viewWillAppear(animated: Bool) {
    self.tableView.tableFooterView = UIView(frame: CGRect.zeroRect)

/// OR 

    self.tableView.tableFooterView = UIView()
}

If you want to add SSL in your test environment, then you can use mkcert. Below I mentioned the GitHub URL.
https://github.com/FiloSottile/mkcert
And also below I mentioned sample nginx configuration for reverse proxy.

server {
        listen 80;
        server_name test.local;
        return 301 https://test.local$request_uri;
}
server {
  listen 443 ssl;
  server_name test.local;
  ssl_certificate /etc/nginx/ssl/test.local.pem;
  ssl_certificate_key /etc/nginx/ssl/test.local-key.pem;

   location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $remote_addr;
      proxy_set_header X-Client-Verify SUCCESS;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
      proxy_pass http://localhost:3000;
      proxy_redirect off;
      proxy_buffering off;
    }
}

Note: I know this is a hack, but it was useful for Angular 1.2 and earlier that didn't provide a simple mechanism.

The validation kicks in on the change event, so some things like changing the values programmatically won't trigger it. But triggering the change event will trigger the validation. For example, with jQuery:

$('#formField1, #formField2').trigger('change');

to make it as globally reuse function using jquery

HTML

<select class="select_location">
   <option value="http://localhost.com/app/page1.html">Page 1</option>
   <option value="http://localhost.com/app/page2.html">Page 2</option>
   <option value="http://localhost.com/app/page3.html">Page 3</option>
</select>

Javascript using jquery

$('.select_location').on('change', function(){
   window.location = $(this).val();
});

now you will able to reuse this function by adding .select_location class to any Select element class

I realize this question was asked nearly 7 years ago but it's still a top Google search result for certain keywords regarding importing excel data with C#, so I wanted to provide an alternative based on some recent tech developments.

Importing Excel data has become such a common task to my everyday duties, that I've streamlined the process and documented the method on my blog: best way to read excel file in c#.

I use NPOI because it can read/write Excel files without Microsoft Office installed and it doesn't use COM+ or any interops. That means it can work in the cloud!

But the real magic comes from pairing up with NPOI Mapper from Donny Tian because it allows me to map the Excel columns to properties in my C# classes without writing any code. It's beautiful.

Here is the basic idea:

I create a .net class that matches/maps the Excel columns I'm interested in:

        class CustomExcelFormat
        {
            [Column("District")]
            public int District { get; set; }

            [Column("DM")]
            public string FullName { get; set; }

            [Column("Email Address")]
            public string EmailAddress { get; set; }

            [Column("Username")]
            public string Username { get; set; }

            public string FirstName
            {
                get
                {
                    return Username.Split('.')[0];
                }
            }

            public string LastName
            {
                get
                {
                    return Username.Split('.')[1];
                }
            }
        }

Notice, it allows me to map based on column name if I want to!

Then when I process the excel file all I need to do is something like this:

        public void Execute(string localPath, int sheetIndex)
        {
            IWorkbook workbook;
            using (FileStream file = new FileStream(localPath, FileMode.Open, FileAccess.Read))
            {
                workbook = WorkbookFactory.Create(file);
            }

            var importer = new Mapper(workbook);
            var items = importer.Take<CustomExcelFormat>(sheetIndex);
            foreach(var item in items)
            {
                var row = item.Value;
                if (string.IsNullOrEmpty(row.EmailAddress))
                    continue;

                UpdateUser(row);
            }

            DataContext.SaveChanges();
        }

Now, admittedly, my code does not modify the Excel file itself. I am instead saving the data to a database using Entity Framework (that's why you see "UpdateUser" and "SaveChanges" in my example). But there is already a good discussion on SO about how to save/modify a file using NPOI.

Untested. Modify to suit:

$form = $('#my-form');

$rows = $form.find('.person-input-row');

$('button#add-new').click(function() {

    $rows.find(':first').clone().insertAfter($rows.find(':last'));

    $justInserted = $rows.find(':last');
    $justInserted.hide();
    $justInserted.find('input').val(''); // it may copy values from first one
    $justInserted.slideDown(500);


});

This is better than copying innerHTML because you will lose all attached events etc.

The best way to do it is:

return this.StatusCode(StatusCodes.Status418ImATeapot, "Error message");

'StatusCodes' has every kind of return status and you can see all of them in this link https://httpstatuses.com/

Once you choose your StatusCode, return it with a message.

In the code of the button that saves the changes to the database eg the update button, add the following lines of code:

MyDataGridView.DataSource = MyTableBindingSource

MyDataGridView.Update()

MyDataGridView.RefreshEdit()

public static boolean isNumeric(String string) {
    if (string == null || string.isEmpty()) {
        return false;
    }
    int i = 0;
    int stringLength = string.length();
    if (string.charAt(0) == '-') {
        if (stringLength > 1) {
            i++;
        } else {
            return false;
        }
    }
    if (!Character.isDigit(string.charAt(i))
            || !Character.isDigit(string.charAt(stringLength - 1))) {
        return false;
    }
    i++;
    stringLength--;
    if (i >= stringLength) {
        return true;
    }
    for (; i < stringLength; i++) {
        if (!Character.isDigit(string.charAt(i))
                && string.charAt(i) != '.') {
            return false;
        }
    }
    return true;
}

Via the page Git Submodule Tutorial:

To remove a submodule you need to:

1. Delete the relevant section from the .gitmodules file.
2. Stage the .gitmodules changes:
   git add .gitmodules
3. Delete the relevant section from .git/config.
4. Remove the submodule files from the working tree and index:
   git rm --cached path_to_submodule (no trailing slash).
5. Remove the submodule's .git directory:
   rm -rf .git/modules/path_to_submodule
6. Commit the changes:
   git commit -m "Removed submodule <name>"
7. Delete the now untracked submodule files:
   rm -rf path_to_submodule

Should do it. Assuming you don't need it to flow.

If you are using pdo, it will look like

$sql = "UPDATE users SET firstname = :firstname, lastname = :lastname WHERE id= :id";
$query = $this->pdo->prepare($sql);
$result = $query->execute(array(':firstname' => $firstname, ':lastname' => $lastname, ':id' => $id));

For this purpose you need to match the location in your apache or any other service you are using

If you are using apache then in httpd.conf file.

  <LocationMatch "/your_relative_path">
      ProxyPass absolute_path_of_your_application/your_relative_path
      ProxyPassReverse absolute_path_of_your_application/your_relative_path
   </LocationMatch>

Go to Xcode -> Project Settings

You can find the way to go to derived Data

If you need the result to be timezone-aware, you can use the replace() method of datetime objects. This preserves timezone, so you can do

>>> from django.utils import timezone
>>> now = timezone.now()
>>> now
datetime.datetime(2018, 8, 30, 14, 15, 43, 726252, tzinfo=<UTC>)
>>> now.replace(hour=0, minute=0, second=0, microsecond=0)
datetime.datetime(2018, 8, 30, 0, 0, tzinfo=<UTC>)

Note that this returns a new datetime object -- now remains unchanged.

You should not map score to player. You should map player (or his name) to score:

Map<Player, Integer> player2score = new HashMap<Player, Integer>();

Then add players to map: int score = .... Player player = new Player(); player.setName("John"); // etc. player2score.put(player, score);

In this case the task is trivial:

int score = player2score.get(player);

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

Go to File -> Settings -> Editor -> Auto Import -> Java and make the below things:

Select Insert imports on paste value to All

Do tick mark on Add unambigious imports on the fly option and "Optimize imports on the fly*

if anyone want to add a value inside loop then you can use this its working 100%

{% set ftotal= {'total': 0} %} 
{%- for pe in payment_entry -%}
    {% if ftotal.update({'total': ftotal.total + 5}) %}{% endif %} 
{%- endfor -%}

{{ftotal.total}}

output = 5

This method Appends the specified element to the end of this list.

add(E e) //append element to the end of the arraylist.

This method Inserts the specified element at the specified position in this list.

void add(int index, E element) //inserts element at the given position in the array list.

This method Replaces the element at the specified position in this list with the specified element.

set(int index, E element) //Replaces the element at the specified position in this list with the specified element.
      

      

Edit 2018: Please look into Object getters and setters and Proxies. Old answer below:

a quick and easy solution goes like this:

var something=999;
var something_cachedValue=something;

function doStuff() {
    if(something===something_cachedValue) {//we want it to match
        setTimeout(doStuff, 50);//wait 50 millisecnds then recheck
        return;
    }
    something_cachedValue=something;
    //real action
}

doStuff();

Specify the maxrecursion option at the end of the query:

...
from EmployeeTree
option (maxrecursion 0)

That allows you to specify how often the CTE can recurse before generating an error. Maxrecursion 0 allows infinite recursion.

With Named arguments:

@Html.ActionLink(linkText: "TestTab", actionName: "TestAction", controllerName: "TestController", routeValues: null, htmlAttributes: new { target = "_blank"})

1. Download the latest build from https://github.com/macvim-dev/macvim/releases

2. Expand the archive.

3. Put MacVim.app into /Applications/.

Done.

I believe that you will have to drop the foreign key constraints first. Then update all of the appropriate tables and remap them as they were.

ALTER TABLE [dbo.Details_tbl] DROP CONSTRAINT [FK_Details_tbl_User_tbl];
-- Perform more appropriate alters
ALTER TABLE [dbo.Details_tbl] ADD FOREIGN KEY (FK_Details_tbl_User_tbl) 
    REFERENCES User_tbl(appId);
-- Perform all appropriate alters to bring the key constraints back

However, unless memory is a really big issue, I would keep the identity as an INT. Unless you are 100% positive that your keys will never grow past the TINYINT restraints. Just a word of caution :)

View view = this.getCurrentFocus();
if (view != null) {  
    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

Try this so you don't need to worry about where your logs are:

dmesg -T | egrep -i 'killed process'

-T - readable timestamps

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

To receive arbitrary Json in Spring-Boot, you can simply use Jackson's JsonNode. The appropriate converter is automatically configured.

    @PostMapping(value="/process")
    public void process(@RequestBody com.fasterxml.jackson.databind.JsonNode payload) {
        System.out.println(payload);
    }

These samples work well. You can check section and then return a height to show or hide section. Don't forget to extend your viewcontroller from UITableViewDelegate.

Objective-C

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    if (section == 0)
    {
        // to hide footer for section 0 
        return 0.0;
    }
    else
    {
        // show footer for every section except section 0 
        return HEIGHT_YOU_WANT;
    }
}

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    UIView *footerView = [[UIView alloc] init];
    footerView.backgroundColor = [UIColor blackColor];
    return footerView;
}

Swift

func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
    let footerView = UIView()
    footerView.backgroundColor = UIColor.black
    return footerView
}

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    if section == 0 {
        // to hide footer for section 0
        return 0.0
    } else {
        // show footer for every section except section 0
        return HEIGHT_YOU_WANT
    }
}

Using a jquery plugin I have adapted it to my needs adding customized options and creating a new plugin. You can find it here: https://github.com/david-dlc-cerezo/jquery-clearField

An example of a simple usage:

<script src='http://code.jquery.com/jquery-1.9.1.js'></script>
<script src='http://code.jquery.com/ui/1.10.3/jquery-ui.js'></script>
<script src='src/jquery.clearField.js'></script>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
<link rel="stylesheet" href="css/jquery.clearField.css">

<table>
    <tr>
        <td><input name="test1" id="test1" clas="test" type='text'></td>
        <td>Empty</td>
    </tr>
    <tr>
        <td><input name="test2" id="test2" clas="test" type='text' value='abc'></td>
        <td>Not empty</td>
    </tr>
</table>

<script>
    $('.test').clearField();
</script>

Obtaining something like this:

You can access the namespace's dictionary with vars():

>>> import argparse
>>> args = argparse.Namespace()
>>> args.foo = 1
>>> args.bar = [1,2,3]
>>> d = vars(args)
>>> d
{'foo': 1, 'bar': [1, 2, 3]}

You can modify the dictionary directly if you wish:

>>> d['baz'] = 'store me'
>>> args.baz
'store me'

Yes, it is okay to access the __dict__ attribute. It is a well-defined, tested, and guaranteed behavior.

I'm sure this isn't a great answer, since it modifies the string it's looping over, but it seems to work alright:

import string
for chr in your_string:
 if chr == ' ':
   your_string = your_string.replace(' ', '_')
 elif chr not in string.ascii_letters or chr not in string.digits:
    your_string = your_string.replace(chr, '')

TL;DR:
SOLUTION (1)

import numpy as np
main_list = np.setdiff1d(list_2,list_1)
# yields the elements in `list_2` that are NOT in `list_1`

SOLUTION (2) You want a sorted list

def setdiff_sorted(array1,array2,assume_unique=False):
    ans = np.setdiff1d(array1,array2,assume_unique).tolist()
    if assume_unique:
        return sorted(ans)
    return ans
main_list = setdiff_sorted(list_2,list_1)

EXPLANATIONS:
(1) You can use NumPy's setdiff1d (array1,array2,assume_unique=False).

assume_unique asks the user IF the arrays ARE ALREADY UNIQUE.
If False, then the unique elements are determined first.
If True, the function will assume that the elements are already unique AND function will skip determining the unique elements.

This yields the unique values in array1 that are not in array2. assume_unique is False by default.

If you are concerned with the unique elements (based on the response of Chinny84), then simply use (where assume_unique=False => the default value):

import numpy as np
list_1 = ["a", "b", "c", "d", "e"]
list_2 = ["a", "f", "c", "m"] 
main_list = np.setdiff1d(list_2,list_1)
# yields the elements in `list_2` that are NOT in `list_1`

(2) For those who want answers to be sorted, I've made a custom function:

import numpy as np
def setdiff_sorted(array1,array2,assume_unique=False):
    ans = np.setdiff1d(array1,array2,assume_unique).tolist()
    if assume_unique:
        return sorted(ans)
    return ans

To get the answer, run:

main_list = setdiff_sorted(list_2,list_1)

SIDE NOTES:
(a) Solution 2 (custom function setdiff_sorted) returns a list (compared to an array in solution 1).

(b) If you aren't sure if the elements are unique, just use the default setting of NumPy's setdiff1d in both solutions A and B. What can be an example of a complication? See note (c).

(c) Things will be different if either of the two lists is not unique.
Say list_2 is not unique: list2 = ["a", "f", "c", "m", "m"]. Keep list1 as is: list_1 = ["a", "b", "c", "d", "e"]
Setting the default value of assume_unique yields ["f", "m"] (in both solutions). HOWEVER, if you set assume_unique=True, both solutions give ["f", "m", "m"]. Why? This is because the user ASSUMED that the elements are unique). Hence, IT IS BETTER TO KEEP assume_unique to its default value. Note that both answers are sorted.

I use superagent, which is simliar to jQuery.

Here is the docs

And the demo like:

var sa = require('superagent');
sa.post('url')
  .send({key: value})
  .end(function(err, res) {
    //TODO
  });

Try this to see how you can create a object from strings.

var firstName = "xx";
var lastName  = "xy";
var phone     = "xz";
var adress    = "x1";
var obj = {"firstName":firstName, "lastName":lastName, "phone":phone, "address":adress};
console.log(obj);

Make sure you are not using the same element Id / class elsewhere, for an element unrelated to the modal component.

That is.. if you are identifying your buttons which trigger the modal popups using the class name 'myModal', ensure that there are no unrelated elements having that same class name.

As we don't know what are the names of your activities classes, let's call your current activity Activity1, and the one you wish to open - Activity2 (these are the names of the classes)

First you need to define an intent that will be sent to Activity2:

Intent launchActivity2 = new Intent(Activity1.this, Activity2.class);

Then, you can simply launch the activity by running:
startActivity(launchActivity2 );

The documentation for Gerrit, in particular the "Push changes" section, explains that you push to the "magical refs/for/'branch' ref using any Git client tool".

The following image is taken from the Intro to Gerrit. When you push to Gerrit, you do git push gerrit HEAD:refs/for/<BRANCH>. This pushes your changes to the staging area (in the diagram, "Pending Changes"). Gerrit doesn't actually have a branch called <BRANCH>; it lies to the git client.

Internally, Gerrit has its own implementation for the Git and SSH stacks. This allows it to provide the "magical" refs/for/<BRANCH> refs.

When a push request is received to create a ref in one of these namespaces Gerrit performs its own logic to update the database, and then lies to the client about the result of the operation. A successful result causes the client to believe that Gerrit has created the ref, but in reality Gerrit hasn’t created the ref at all. [Link - Gerrit, "Gritty Details"].

After a successful patch (i.e, the patch has been pushed to Gerrit, [putting it into the "Pending Changes" staging area], reviewed, and the review has passed), Gerrit pushes the change from the "Pending Changes" into the "Authoritative Repository", calculating which branch to push it into based on the magic it did when you pushed to refs/for/<BRANCH>. This way, successfully reviewed patches can be pulled directly from the correct branches of the Authoritative Repository.

I think you may be overthinking this.

My approach is simple.

Enclose you page with a div tag:

<div id="mydiv">
<!-- you page here -->
</div>

In your javascript:

var html=document.getElementById('mydiv').innerHTML;
html = html.replace(/this/g,"that");
document.getElementById('mydiv').innerHTML=html;

You should be able to find your command with a ps variant like:

ps -ef
ps -fubob # if your job's user ID is bob.

Then, once located, it should be a simple matter to use kill to kill the process (permissions permitting).

If you're talking about getting rid of jobs in the at queue (that aren't running yet), you can use atq to list them and atrm to get rid of them.

Update

If your popover is going to have a selector that is consistent then you can make use of selector property of popover constructor.

var popOverSettings = {
    placement: 'bottom',
    container: 'body',
    html: true,
    selector: '[rel="popover"]', //Sepcify the selector here
    content: function () {
        return $('#popover-content').html();
    }
}

$('body').popover(popOverSettings);

Demo

Other ways:

1. (Standard Way) Bind the popover again to the new items being inserted. Save the popoversettings in an external variable.
2. Use Mutation Event/Mutation Observer to identify if a particular element has been inserted on to the ul or an element.

Source

var popOverSettings = { //Save the setting for later use as well
    placement: 'bottom',
    container: 'body',
    html: true,
    //content:" <div style='color:red'>This is your div content</div>"
    content: function () {
        return $('#popover-content').html();
    }

}

$('ul').on('DOMNodeInserted', function () { //listed for new items inserted onto ul
    $(event.target).popover(popOverSettings);
});

$("button[rel=popover]").popover(popOverSettings);
$('.pop-Add').click(function () {
    $('ul').append("<li class='project-name'>     <a>project name 2        <button class='pop-function' rel='popover'></button>     </a>   </li>");
});

But it is not recommended to use DOMNodeInserted Mutation Event for performance issues as well as support. This has been deprecated as well. So your best bet would be to save the setting and bind after you update with new element.

Demo

Another recommended way is to use MutationObserver instead of MutationEvent according to MDN, but again support in some browsers are unknown and performance a concern.

MutationObserver = window.MutationObserver || window.WebKitMutationObserver;
// create an observer instance
var observer = new MutationObserver(function (mutations) {
    mutations.forEach(function (mutation) {
        $(mutation.addedNodes).popover(popOverSettings);
    });
});

// configuration of the observer:
var config = {
     attributes: true, 
     childList: true, 
     characterData: true
};

// pass in the target node, as well as the observer options
observer.observe($('ul')[0], config);

Demo

This should work. I converted the date to unix time via strtotime.

  foreach ($originalArray as $key => $part) {
       $sort[$key] = strtotime($part['datetime']);
  }
  array_multisort($sort, SORT_DESC, $originalArray);

One-liner version would be using multiple array methods:

array_multisort(array_map('strtotime',array_column($originalArray,'datetime')),
                SORT_DESC, 
                $originalArray);

Here is a YUI compressor script (Byuic) that finds all the js and css down a path and compresses /(optionally) obfuscates them. Nice to integrate into a build process.

Delete .android folder cache files, Also delete the build folder manually from a directory and open android studio and run again.

Referencing the Rails documents we see that there are a few ways to link to images from css. Just go to section 2.3.2.

First, make sure your css file has the .scss extension if it's a sass file.

Next, you can use the ruby method, which is really ugly:

#logo { background: url(<%= asset_data_uri 'logo.png' %>) }

Or you can use the specific form that is nicer:

image-url("rails.png") returns url(/assets/rails.png)
image-path("rails.png") returns "/assets/rails.png"

Lastly, you can use the general form:

asset-url("rails.png") returns url(/assets/rails.png)
asset-path("rails.png") returns "/assets/rails.png"

The error is happening because you (or whoever designed this table) have a bunch of dates in VARCHAR. Why are you (or whoever designed this table) storing dates as strings? Do you (or whoever designed this table) also store salary and prices and distances as strings?

To find the values that are causing issues (so you (or whoever designed this table) can fix them):

SELECT GRADUATION_DATE FROM mydb
  WHERE ISDATE(GRADUATION_DATE) = 0;

Bet you have at least one row. Fix those values, and then FIX THE TABLE. Or ask whoever designed the table to FIX THE TABLE. Really nicely.

ALTER TABLE mydb ALTER COLUMN GRADUATION_DATE DATE;

Now you don't have to worry about the formatting - you can always format as YYYYMMDD or YYYY-MM-DD on the client, or using CONVERT in SQL. When you have a valid date as a string literal, you can use:

SELECT CONVERT(CHAR(10), '20120101', 120);

...but this is better done on the client (if at all).

There's a popular term - garbage in, garbage out. You're never going to be able to convert to a date (never mind convert to a string in a specific format) if your data type choice (or the data type choice of whoever designed the table) inherently allows garbage into your table. Please fix it. Or ask whoever designed the table (again, really nicely) to fix it.

when we run application in eclipse apk generate is sign by default Keystore which is provided by android .

But if you want to upload your application on play store you need to create your own keystore. Eclipse already provides GUI interface to create new keystore. And you also can create keystore through command line.

default alias is

androiddebugkey

You have to pass the -np/--no-parent option to wget (in addition to -r/--recursive, of course), otherwise it will follow the link in the directory index on my site to the parent directory. So the command would look like this:

wget --recursive --no-parent http://example.com/configs/.vim/

To avoid downloading the auto-generated index.html files, use the -R/--reject option:

wget -r -np -R "index.html*" http://example.com/configs/.vim/

In my case, my array was multidimensional, potentially with arrays as values. So I created this recursive function to blow apart the array completely:

function array2csv($array, &$title, &$data) {
    foreach($array as $key => $value) {      
        if(is_array($value)) {
            $title .= $key . ",";
            $data .= "" . ",";
            array2csv($value, $title, $data);
        } else {
            $title .= $key . ",";
            $data .= '"' . $value . '",';
        }
    }
}

Since the various levels of my array didn't lend themselves well to a the flat CSV format, I created a blank column with the sub-array's key to serve as a descriptive "intro" to the next level of data. Sample output:

agentid     fname           lname      empid    totals  sales   leads   dish    dishnet top200_plus top120  latino  base_packages
G-adriana   ADRIANA EUGENIA PALOMO PAIZ 886                0    19              0         0         0         0      0

You could easily remove that "intro" (descriptive) column, but in my case I had repeating column headers, i.e. inbound_leads, in each sub-array, so that gave me a break/title preceding the next section. Remove:

$title .= $key . ",";
$data .= "" . ",";

after the is_array() to compact the code further and remove the extra column.

Since I wanted both a title row and data row, I pass two variables into the function and upon completion of the call to the function, terminate both with PHP_EOL:

$title .= PHP_EOL;
$data .= PHP_EOL;

Yes, I know I leave an extra comma, but for the sake of brevity, I didn't handle it here.

People say you can't and I understand you may be frustrated when asking a question and getting such an answer.

If you really want it to show in UTF-8 instead of US ASCII then you need to do it in two steps.

First:

iconv -f us-ascii -t utf-16 yourfile > youfileinutf16.*

Second:

iconv -f utf-16le -t utf-8 yourfileinutf16 > yourfileinutf8.*

Then if you do a file -i, you'll see the new character set is UTF-8.

In order to get around the Enable Macro prompt I suggest

Application.AutomationSecurity = msoAutomationSecurityForceDisable

Be sure to return it to default when you are done

Application.AutomationSecurity = msoAutomationSecurityLow

A reminder that the .SaveAs function contains all optional arguments.I recommend removing CreatBackup:= False as it is not necessary.

The most interesting way I think is to create an object of the workbook and access the .SaveAs property that way. I have not tested it but you are never using Workbooks.Open rendering Application.AutomationSecurity inapplicable. Possibly saving resources and time as well.

That said I was able to execute the following without any notifications on Excel 2013 windows 10.

    Option Explicit

    "F:\VBA Macros\Stack Overflow Questions\When changing type xlsm to xlsx_ 
    stop popup\Book1.xlsx" _
    , FileFormat:=xlOpenXMLWorkbook

    ActiveWorkbook.Close

    Application.AutomationSecurity = msoAutomationSecurityLow 
    'make sure you set this up when done

    Kill ("F:\VBA Macros\Stack Overflow Questions\When changing type xlsm_

Here was an answer baked into the default ASP.NET MVC 5 project I believe that accomplishes my styling goals nicely in the UI. Form submit using pure javascript to some containing form.

@using (Html.BeginForm("Logout", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
{
   <a href="javascript:document.getElementById('logoutForm').submit()">
      <span>Sign out</span>
   </a>
}

The fully shown use case is a logout dropdown in the navigation bar of a web app.

@using (Html.BeginForm("Logout", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
{
    @Html.AntiForgeryToken()

    <div class="dropdown">
        <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
            <span class="ma-nav-text ma-account-name">@User.Identity.Name</span>
            <i class="material-icons md-36 text-inverse">person</i>
        </button>

        <ul class="dropdown-menu dropdown-menu-right ma-dropdown-tray">
            <li>
                <a href="javascript:document.getElementById('logoutForm').submit()">
                    <i class="material-icons">system_update_alt</i>
                    <span>Sign out</span>
                </a>
            </li>
        </ul>
    </div>
}

As many have stated more or less correctly what reference and primitive types are, one might be interested that we have some more relevant types in Java. Here is the complete lists of types in java (as far as I am aware of (JDK 11)).

Primitive Type

Describes a value (and not a type).

11

Reference Type

Describes a concrete type which instances extend Object (interface, class, enum, array). Furthermore TypeParameter is actually a reference type!

Integer

Note: The difference between primitive and reference type makes it necessary to rely on boxing to convert primitives in Object instances and vise versa.

Note2: A type parameter describes a type having an optional lower or upper bound and can be referenced by name within its context (in contrast to the wild card type). A type parameter typically can be applied to parameterized types (classes/interfaces) and methods. The parameter type defines a type identifier.

Wildcard Type

Expresses an unknown type (like any in TypeScript) that can have a lower or upper bound by using super or extend.

? extends List<String>
? super ArrayList<String>

Void Type

Nothingness. No value/instance possible.

void method();

Null Type

The only representation is 'null'. It is used especially during type interference computations. Null is a special case logically belonging to any type (can be assigned to any variable of any type) but is actual not considered an instance of any type (e.g. (null instanceof Object) == false).

null

Union Type

A union type is a type that is actual a set of alternative types. Sadly in Java it only exists for the multi catch statement.

catch(IllegalStateException | IOException e) {}

Interference Type

A type that is compatibile to multiple types. Since in Java a class has at most one super class (Object has none), interference types allow only the first type to be a class and every other type must be an interface type.

void method(List<? extends List<?> & Comparable> comparableList) {}

Unknown Type

The type is unknown. That is the case for certain Lambda definitions (not enclosed in brackets, single parameter).

list.forEach(element -> System.out.println(element.toString)); //element is of unknown type

Var Type

Unknown type introduced by a variable declaration spotting the 'var' keyword.

var variable = list.get(0);

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.

install RVM:

\curl -L https://get.rvm.io | 
  bash -s stable --ruby --autolibs=enable --auto-dotfiles

If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanation.

If you want to match the two words in either order, use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)|(Failed.*VendorEnquiry)'

If Failed always comes after VendorEnquiry on the line, just use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)'

l=[[0]*(L) for _ in range(W)]

Will be faster than:

l = [[0 for x in range(L)] for y in range(W)] 

Use character classes: [ \t]

If you right click on any result of "Edit Top 200 Rows" query in SSMS you will see the option "Pane -> SQL". It then shows the SQL Query that was run, which you can edit as you wish.

In SMSS 2012 and 2008, you can use Ctrl+3 to quickly get there.

Something like this?

public static T ConvertValue<T>(string value)
{
    return (T)Convert.ChangeType(value, typeof(T));
}

You can then use it like this:

int val = ConvertValue<int>("42");

Edit:

You can even do this more generic and not rely on a string parameter provided the type U implements IConvertible - this means you have to specify two type parameters though:

public static T ConvertValue<T,U>(U value) where U : IConvertible
{
    return (T)Convert.ChangeType(value, typeof(T));
}

I considered catching the InvalidCastException exception that might be raised by Convert.ChangeType() - but what would you return in this case? default(T)? It seems more appropriate having the caller deal with the exception.

You can do it with IE 'sometimes' as I have done this for an internal application on an intranet which is IE only. Try the following:

function GetComputerName() {
    try {
        var network = new ActiveXObject('WScript.Network');
        // Show a pop up if it works
        alert(network.computerName);
    }
    catch (e) { }
}

It may or may not require some specific security setting setup in IE as well to allow the browser to access the ActiveX object.

Here is a link to some more info on WScript: More Information

element.remove()

The DOM is organized in a tree of nodes, where each node has a value, along with a list of references to its child nodes. So element.parentNode.removeChild(element) mimics exactly what is happening internally: First you go the parent node, then remove the reference to the child node.

As of DOM4, a helper function is provided to do the same thing: element.remove(). This works in 96% of browsers (as of 2020), but not IE 11. If you need to support older browsers, you can:

• Remove elements via the parent node, as in the question,
• modify the native DOM functions, as in Johan Dettmar's answer, or
• use a DOM4 polyfill.

int countRow = dt.Rows.Count;
int countCol = dt.Columns.Count;

for (int iCol = 0; iCol < countCol; iCol++)
{
     DataColumn col = dt.Columns[iCol];

     for (int iRow = 0; iRow < countRow; iRow++)
     {
         object cell = dt.Rows[iRow].ItemArray[iCol];

     }
}

npm ws was the answer for me. I found it less intrusive and more straight forward. With it was also trivial to mix websockets with rest services. Shared simple code on this post.

var WebSocketServer = require("ws").Server;
var http = require("http");
var express = require("express");
var port = process.env.PORT || 5000;

var app = express();
    app.use(express.static(__dirname+ "/../"));
    app.get('/someGetRequest', function(req, res, next) {
       console.log('receiving get request');
    });
    app.post('/somePostRequest', function(req, res, next) {
       console.log('receiving post request');
    });
    app.listen(80); //port 80 need to run as root

    console.log("app listening on %d ", 80);

var server = http.createServer(app);
    server.listen(port);

console.log("http server listening on %d", port);

var userId;
var wss = new WebSocketServer({server: server});
    wss.on("connection", function (ws) {

    console.info("websocket connection open");

    var timestamp = new Date().getTime();
    userId = timestamp;

    ws.send(JSON.stringify({msgType:"onOpenConnection", msg:{connectionId:timestamp}}));


    ws.on("message", function (data, flags) {
        console.log("websocket received a message");
        var clientMsg = data;

        ws.send(JSON.stringify({msg:{connectionId:userId}}));


    });

    ws.on("close", function () {
        console.log("websocket connection close");
    });
});
console.log("websocket server created");

I've just checked and i have the same code as you and it works perferctly. The only difference is how i fill my List for the params :

I use a : ArrayList<BasicNameValuePair> params

and fill it this way :

 params.add(new BasicNameValuePair("apikey", apikey);

I do not use any JSONObject to send params to the webservices.

Are you obliged to use the JSONObject ?

Every time you call itr2.next() you are getting a distinct value. Not the same value. You should only call this once in the loop.

Iterator<String> itr2 = keys.iterator();
    while(itr2.hasNext()){
        String v = itr2.next();
        System.out.println("Key: "+v+" ,value: "+m.get(v));
    }

Check to make sure there is a film release date; if the date is missing you will not be able to format on a non-object.

if ($info['Film_Release']){ //check if the date exists
   $dateFromDB = $info['Film_Release'];
   $newDate = DateTime::createFromFormat("l dS F Y", $dateFromDB);
   $newDate = $newDate->format('d/m/Y'); 
} else {
   $newDate = "none"; 
}

or

 $newDate = ($info['Film_Release']) ? DateTime::createFromFormat("l dS F Y", $info['Film_Release'])->format('d/m/Y'): "none" 

I believe that if you download the offline ISO image file, and use that to install Visual Studio Express, you won't have to register.

Go here and find the link that says "All - Offline Install ISO image file". Click on it to expand it, select your language, and then click "Download".

Otherwise, it's possible that online registration is simply down for a while, as the error message indicates. You have 30 days before it expires, so give it a few days before starting to panic.

Try this simpler one,

cp /home/ankur/folder/file{1,2} /home/ankur/dest

If you want to copy all the 10 files then run this command,

 cp ~/Desktop/{xyz,file{1,2},next,files,which,are,not,similer} foo-bar

Not only is the boolean datatype missing in Oracle's SQL (not PL/SQL), but they also have no clear recommendation about what to use instead. See this thread on asktom. From recommending CHAR(1) 'Y'/'N' they switch to NUMBER(1) 0/1 when someone points out that 'Y'/'N' depends on the English language, while e.g. German programmers might use 'J'/'N' instead.

The worst thing is that they defend this stupid decision just like they defend the ''=NULL stupidity.

I have used the extremely handy app_offline.htm trick to shut down/update sites in the past without any issues.

Be sure that you are actually placing the "app_offline.htm" file in the "root" of the website that you have configured within IIS.

Also ensure that the file is named exactly as it should be: app_offline.htm

Other than that, there should be no other changes to IIS that you should need to make since the processing of this file (with this specific name) is handled by the ASP.NET runtime rather than IIS itself (for IIS v6).

Be aware, however, that although placing this file in the root of your site will force the application to "shut down" and display the content of the "app_offline.htm" file itself, any existing requests will still get the real website served up to them. Only new requests will get the app_offline.htm content.

If you're still having issues, try the following links for further info:

Scott Gu's App_Offline.htm

App_Offline.htm and working around the "IE Friendly Errors" feature

Will app_offline.htm stop current requests or just new requests?

            List<Messages> result1 = MsgList.Where(o => !sentMsgIDs.Contains(o.MsgID)).ToList<Messages>();

Hope it should help.

canvas.toDataURL is not working if the original image URL (either relative or absolute) does not belong to the same domain as the web page. Tested from a bookmarklet and a simple javascript in the web page containing the images. Have a look to David Walsh working example. Put the html and images on your own web server, switch original image to relative or absolute URL, change to an external image URL. Only the first two cases are working.

From JQuery Documentation

The jqXHR objects returned by $.ajax() as of jQuery 1.5 implement the Promise interface, giving them all the properties, methods, and behavior of a Promise (see Deferred object for more information). These methods take one or more function arguments that are called when the $.ajax() request terminates. This allows you to assign multiple callbacks on a single request, and even to assign callbacks after the request may have completed. (If the request is already complete, the callback is fired immediately.) Available Promise methods of the jqXHR object include:

jqXHR.done(function( data, textStatus, jqXHR ) {});

An alternative construct to the success callback option, refer to deferred.done() for implementation details.

jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {});

An alternative construct to the error callback option, the .fail() method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.

jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { }); 

(added in jQuery 1.6) An alternative construct to the complete callback option, the .always() method replaces the deprecated .complete() method.

In response to a successful request, the function's arguments are the same as those of .done(): data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail(): the jqXHR object, textStatus, and errorThrown. Refer to deferred.always() for implementation details.

jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {});

Incorporates the functionality of the .done() and .fail() methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then() for implementation details.

Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

In Python 3, / is float division

In Python 2, / is integer division (assuming int inputs)

In both 2 and 3, // is integer division

(To get float division in Python 2 requires either of the operands be a float, either as 20. or float(20))

Scikit learn introduced a delicious new method called export_text in version 0.21 (May 2019) to extract the rules from a tree. Documentation here. It's no longer necessary to create a custom function.

Once you've fit your model, you just need two lines of code. First, import export_text:

from sklearn.tree import export_text

Second, create an object that will contain your rules. To make the rules look more readable, use the feature_names argument and pass a list of your feature names. For example, if your model is called model and your features are named in a dataframe called X_train, you could create an object called tree_rules:

tree_rules = export_text(model, feature_names=list(X_train.columns))

Then just print or save tree_rules. Your output will look like this:

|--- Age <= 0.63
|   |--- EstimatedSalary <= 0.61
|   |   |--- Age <= -0.16
|   |   |   |--- class: 0
|   |   |--- Age >  -0.16
|   |   |   |--- EstimatedSalary <= -0.06
|   |   |   |   |--- class: 0
|   |   |   |--- EstimatedSalary >  -0.06
|   |   |   |   |--- EstimatedSalary <= 0.40
|   |   |   |   |   |--- EstimatedSalary <= 0.03
|   |   |   |   |   |   |--- class: 1

In batch you could do it like this:

@echo off

setlocal EnableDelayedExpansion

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do (
  set "var=%%sxyz"
  svn co "!var!"
)

If you don't need the variable !var! elsewhere in the loop, you could simplify that to

@echo off

setlocal

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do svn co "%%sxyz"

However, like C.B. I'd prefer PowerShell if at all possible:

$string_list = 'str1', 'str2', 'str3', ... 'str10'

$string_list | ForEach-Object {
  $var = "${_}xyz"   # alternatively: $var = $_ + 'xyz'
  svn co $var
}

Again, this could be simplified if you don't need $var elsewhere in the loop:

$string_list = 'str1', 'str2', 'str3', ... 'str10'
$string_list | ForEach-Object { svn co "${_}xyz" }

If you are a Photoshop guy, you can also use:

 #some-element {
  background-color: hsla(170, 50%, 45%, 0.9); // **0.9 is the opacity range from 0 - 1**
 }

Or:

#some-element {
  background-color: rgba(170, 190, 45, 0.9); // **0.9 is the opacity range from 0 - 1**
}

Declare the variable as a string.

example :

public string dateOfBirth ;

then assign a value like :

dateOfBirth = ((DateTime)(datetimevaluefromDB)).ToShortDateString();

$scope.actions.data.concat is not a function 

same problem with me but i solve the problem by

 $scope.actions.data = [].concat($scope.actions.data , data)

First you need to know the exact name of the INDEX (Unique key in this case) to delete or update it.
INDEX names are usually same as column names. In case of more than one INDEX applied on a column, MySQL automatically suffixes numbering to the column names to create unique INDEX names.

For example if 2 indexes are applied on a column named customer_id

1. The first index will be named as customer_id itself.
2. The second index will be names as customer_id_2 and so on.

To know the name of the index you want to delete or update

SHOW INDEX FROM <table_name>

as suggested by @Amr

To delete an index

ALTER TABLE <table_name> DROP INDEX <index_name>;

The basic one, ask tasklist to filter its output and only show the indicated process id information

tasklist /fi "pid eq 4444" 

To only get the process name, the line must be splitted

for /f "delims=," %%a in ('
    tasklist /fi "pid eq 4444" /nh /fo:csv
') do echo %%~a

In this case, the list of processes is retrieved without headers (/nh) in csv format (/fo:csv). The commas are used as token delimiters and the first token in the line is the image name

note: In some windows versions (one of them, my case, is the spanish windows xp version), the pid filter in the tasklist does not work. In this case, the filter over the list of processes must be done out of the command

for /f "delims=," %%a in ('
    tasklist /fo:csv /nh ^| findstr /b /r /c:"[^,]*,\"4444\","

This will generate the task list and filter it searching for the process id in the second column of the csv output.

Rather than abusing plot or annotate, which will be inefficient for many lines, you can use matplotlib.collections.LineCollection:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.collections import LineCollection

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")

# Takes list of lines, where each line is a sequence of coordinates
l1 = [(70, 100), (70, 250)]
l2 = [(70, 90), (90, 200)]
lc = LineCollection([l1, l2], color=["k","blue"], lw=2)

plt.gca().add_collection(lc)

plt.show()

It takes a list of lines [l1, l2, ...], where each line is a sequence of N coordinates (N can be more than two).

The standard formatting keywords are available, accepting either a single value, in which case the value applies to every line, or a sequence of M values, in which case the value for the ith line is values[i % M].

try this:

ren "File 1-1" "File 1 - %date:/=-% %time::=-%"

Dim pos, arr, val

arr=Array(1,2,4,5)
val = 4

pos=Application.Match(val, arr, False)

if not iserror(pos) then
   Msgbox val & " is at position " & pos
else
   Msgbox val & " not found!"
end if

Updated to show using Match (with .Index) to find a value in a dimension of a two-dimensional array:

Dim arr(1 To 10, 1 To 2)
Dim x

For x = 1 To 10
    arr(x, 1) = x
    arr(x, 2) = 11 - x
Next x

Debug.Print Application.Match(3, Application.Index(arr, 0, 1), 0)
Debug.Print Application.Match(3, Application.Index(arr, 0, 2), 0)

EDIT: it's worth illustrating here what @ARich pointed out in the comments - that using Index() to slice an array has horrible performance if you're doing it in a loop.

In testing (code below) the Index() approach is almost 2000-fold slower than using a nested loop.

Sub PerfTest()

    Const VAL_TO_FIND As String = "R1800:C8"
    Dim a(1 To 2000, 1 To 10)
    Dim r As Long, c As Long, t

    For r = 1 To 2000
        For c = 1 To 10
            a(r, c) = "R" & r & ":C" & c
        Next c
    Next r

    t = Timer
    Debug.Print FindLoop(a, VAL_TO_FIND), Timer - t
    ' >> 0.00781 sec

     t = Timer
    Debug.Print FindIndex(a, VAL_TO_FIND), Timer - t
    ' >> 14.18 sec

End Sub

Function FindLoop(arr, val) As Boolean
    Dim r As Long, c As Long
    For r = 1 To UBound(arr, 1)
    For c = 1 To UBound(arr, 2)
        If arr(r, c) = val Then
            FindLoop = True
            Exit Function
        End If
    Next c
    Next r
End Function

Function FindIndex(arr, val)
    Dim r As Long
    For r = 1 To UBound(arr, 1)
        If Not IsError(Application.Match(val, Application.Index(arr, r, 0), 0)) Then
            FindIndex = True
            Exit Function
        End If
    Next r
End Function

keep it simple. Most modern browsers support a maxlength attribute on a text area (IE included), so simply add that attribute in code-behind. No JS, no Jquery, no inheritance, custom code, no fuss, no muss.

VB.Net:

fld_description.attributes("maxlength") = 255

C#

fld_description.Attributes["maxlength"] = 255

The Date object is used to work with dates and times.

Date objects are created with new Date().

var date= new Date();

 function myFunction() {
        var currentTime = new Date();
        Logger.log(currentTime);
    }

Not with the HTML file control, no. A flash file uploader can do that for you though. You could use some client-side code to check for the PDF extension after they select, but you cannot directly control what they can select.

1. Create a UNIQUE constraint on your subs_email column, if one does not already exist:

   ALTER TABLE subs ADD UNIQUE (subs_email)
   

2. Use INSERT ... ON DUPLICATE KEY UPDATE:

   INSERT INTO subs
     (subs_name, subs_email, subs_birthday)
   VALUES
     (?, ?, ?)
   ON DUPLICATE KEY UPDATE
     subs_name     = VALUES(subs_name),
     subs_birthday = VALUES(subs_birthday)
   

You can use the VALUES(col_name) function in the UPDATE clause to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE - dev.mysql.com

3. Note that I have used parameter placeholders in the place of string literals, as one really should be using parameterised statements to defend against SQL injection attacks.

If you do not have an LDF file then:

1) put the MDF in the C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\

2) In ssms, go to Databases -> Attach and add the MDF file. It will not let you add it this way but it will tell you the database name contained within.

3) Make sure the user you are running ssms.exe as has acccess to this MDF file.

4) Now that you know the DbName, run

EXEC sp_attach_single_file_db @dbname = 'DbName', 
@physname = N'C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\yourfile.mdf';

If you're removing the path for Python 3 specifically, I found it in ~/.zprofile and ~/.zshrc.

Xcode 8 beta 2 • Swift 3

let myString = "Hello World"
let myRange = myString.startIndex..<myString.index(myString.startIndex, offsetBy: 5)
let mySubString = myString.substring(with: myRange)   // Hello

Xcode 7 • Swift 2.0

let myString = "Hello World"
let myRange = Range<String.Index>(start: myString.startIndex, end: myString.startIndex.advancedBy(5))

let mySubString = myString.substringWithRange(myRange)   // Hello

or simply

let myString = "Hello World"
let myRange = myString.startIndex..<myString.startIndex.advancedBy(5)
let mySubString = myString.substringWithRange(myRange)   // Hello

How about:

String numbers = text.substring(text.length() - 7);

That assumes that there are 7 characters at the end, of course. It will throw an exception if you pass it "12345". You could address that this way:

String numbers = text.substring(Math.max(0, text.length() - 7));

or

String numbers = text.length() <= 7 ? text : text.substring(text.length() - 7);

Note that this still isn't doing any validation that the resulting string contains numbers - and it will still throw an exception if text is null.

Pass your Image URL: Try this:

private Bitmap getBitmap(String url) 
    {
        File file=fileCache.getFile(url);
        Bitmap bm = decodeFile(file);
        if(bm!=null) 
            return bm;
        try {
            Bitmap bitmap=null;
            URL ImageUrl = new URL(url);
            HttpURLConnection conn = (HttpURLConnection)ImageUrl.openConnection();
            conn.setConnectTimeout(50000);
            conn.setReadTimeout(50000);
            conn.setInstanceFollowRedirects(true);
            InputStream is = conn.getInputStream();
            OutputStream os = new FileOutputStream(file);
            Utils.CopyStream(is, os);
            os.close();
            bitmap = decodeFile(file);
            return bitmap;
        } catch (Exception ex){
           ex.printStackTrace();
           return null;
        }
    }
    private Bitmap decodeFile(File file){
        try {
            BitmapFactory.Options opt = new BitmapFactory.Options();
            opt.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(new FileInputStream(file),null,opt);
            final int REQUIRED_SIZE=70;
            int width_tmp=opt.outWidth, height_tmp=opt.outHeight;
            int scale=1;
            while(true){
                if(width_tmp/2<REQUIRED_SIZE || height_tmp/2<REQUIRED_SIZE)
                    break;
                width_tmp/=2;
                height_tmp/=2;
                scale*=2;
            }
            BitmapFactory.Options opte = new BitmapFactory.Options();
            opte.inSampleSize=scale;
            return BitmapFactory.decodeStream(new FileInputStream(file), null, opte);
        } catch (FileNotFoundException e) {}
        return null;
    }

Create Class Utils:

public class Utils {
    public static void CopyStream(InputStream is, OutputStream os)
    {
        final int buffer_size=1024;
        try
        {
            byte[] bytes=new byte[buffer_size];
            for(;;)
            {
              int count=is.read(bytes, 0, buffer_size);
              if(count==-1)
                  break;
              os.write(bytes, 0, count);
            }
        }
        catch(Exception ex){}
    }
}

A fixed number can't be set for port, heroku assigns it dynamically using process.env.PORT. But you can add them both, like this process.env.PORT || 5000. Heroku will use the first one, and your localhost will use the second one.

You can even add your call back function. Look at the code below

app.listen(process.env.PORT || 5000, function() {
    console.log("Server started.......");
});

on my quest to do this with entitie, i stumbled over here, just hitting back to post what i've found out...

when using EF4, "a sql's" datetime column can be filled from .NET's DateTime using BitConverter.

EntitieObj.thetime = BitConverter.GetBytes(DateTime.Now.ToBinary());

also Fakrudeen's link brought me further... thank you.

To replace from the right:

def replace_right(source, target, replacement, replacements=None):
    return replacement.join(source.rsplit(target, replacements))

In use:

>>> replace_right("asd.asd.asd.", ".", ". -", 1)
'asd.asd.asd. -'

You can use LambdaEqualityComparer:

var distinctValues
    = myCustomerList.Distinct(new LambdaEqualityComparer<OurType>((c1, c2) => c1.CustomerId == c2.CustomerId));


public class LambdaEqualityComparer<T> : IEqualityComparer<T>
    {
        public LambdaEqualityComparer(Func<T, T, bool> equalsFunction)
        {
            _equalsFunction = equalsFunction;
        }

        public bool Equals(T x, T y)
        {
            return _equalsFunction(x, y);
        }

        public int GetHashCode(T obj)
        {
            return obj.GetHashCode();
        }

        private readonly Func<T, T, bool> _equalsFunction;
    }

If you are using SQL Express (which you are), then your login credentials are .\SQLEXPRESS

Here is the connectionString in the web config file which you can add:

<connectionStrings>
<add connectionString="Server=localhost\SQLEXPRESS;Database=yourDBName;Initial Catalog= yourDBName;Integrated Security=true" name="nametoCallBy" providerName="System.Data.SqlClient"/>
</connectionStrings>

Place is just above the system.web tag.

Then you can call it by:

connString = ConfigurationManager.ConnectionStrings["nametoCallBy"].ConnectionString;

Python lists are mutable objects and here:

plot_data = [[]] * len(positions) 

you are repeating the same list len(positions) times.

>>> plot_data = [[]] * 3
>>> plot_data
[[], [], []]
>>> plot_data[0].append(1)
>>> plot_data
[[1], [1], [1]]
>>> 

Each list in your list is a reference to the same object. You modify one, you see the modification in all of them.

If you want different lists, you can do this way:

plot_data = [[] for _ in positions]

for example:

>>> pd = [[] for _ in range(3)]
>>> pd
[[], [], []]
>>> pd[0].append(1)
>>> pd
[[1], [], []]

Applying the full_extent() function in an answer by @Joe 3 years later from here, you can get exactly what the OP was looking for. Alternatively, you can use Axes.get_tightbbox() which gives a little tighter bounding box

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
from matplotlib.transforms import Bbox

def full_extent(ax, pad=0.0):
    """Get the full extent of an axes, including axes labels, tick labels, and
    titles."""
    # For text objects, we need to draw the figure first, otherwise the extents
    # are undefined.
    ax.figure.canvas.draw()
    items = ax.get_xticklabels() + ax.get_yticklabels() 
#    items += [ax, ax.title, ax.xaxis.label, ax.yaxis.label]
    items += [ax, ax.title]
    bbox = Bbox.union([item.get_window_extent() for item in items])

    return bbox.expanded(1.0 + pad, 1.0 + pad)

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = full_extent(ax2).transformed(fig.dpi_scale_trans.inverted())
# Alternatively,
# extent = ax.get_tightbbox(fig.canvas.renderer).transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

ADD following -

• look up for: # The MySQL server [mysqld]
• add this right below it: lower_case_table_names = 1 In file - /etc/mysql/mysql.conf.d/mysqld.cnf

It's works for me.

You need to use the library project located at: ANDROID-SDK-DIRECTORY/extras/google/google_play_services/libproject

This will fix your first issue.

I'm not sure about your second, but it may be a side effect of the first. I am still trying to get the map working in my own app :)

You can't have multiple actions with the same name. You could add a parameter to one method and that would be valid. For example:

    public ActionResult Index(int i)
    {
        Some Code--Some Code---Some Code
        return View();
    }

There are a few ways to do to have actions that differ only by request verb. My favorite and, I think, the easiest to implement is to use the AttributeRouting package. Once installed simply add an attribute to your method as follows:

  [GET("Resources")]
  public ActionResult Index()
  {
      return View();
  }

  [POST("Resources")]
  public ActionResult Create()
  {
      return RedirectToAction("Index");
  }

In the above example the methods have different names but the action name in both cases is "Resources". The only difference is the request verb.

The package can be installed using NuGet like this:

PM> Install-Package AttributeRouting

If you don't want the dependency on the AttributeRouting packages you could do this by writing a custom action selector attribute.

TO answer your question: no, MySQL does not support Table-typed variables in the same manner that SQL Server (http://msdn.microsoft.com/en-us/library/ms188927.aspx) provides. Oracle provides similar functionality but calls them Cursor types instead of table types (http://docs.oracle.com/cd/B12037_01/appdev.101/b10807/13_elems012.htm).

Depending your needs you can simulate table/cursor-typed variables in MySQL using temporary tables in a manner similar to what is provided by both Oracle and SQL Server.

However, there is an important difference between the temporary table approach and the table/cursor-typed variable approach and it has a lot of performance implications (this is the reason why Oracle and SQL Server provide this functionality over and above what is provided with temporary tables).

Specifically: table/cursor-typed variables allow the client to collate multiple rows of data on the client side and send them up to the server as input to a stored procedure or prepared statement. What this eliminates is the overhead of sending up each individual row and instead pay that overhead once for a batch of rows. This can have a significant impact on overall performance when you are trying to import larger quantities of data.

A possible work-around:

What you may want to try is creating a temporary table and then using a LOAD DATA (http://dev.mysql.com/doc/refman/5.1/en/load-data.html) command to stream the data into the temporary table. You could then pass them name of the temporary table into your stored procedure. This will still result in two calls to the database server, but if you are moving enough rows there may be a savings there. Of course, this is really only beneficial if you are doing some kind of logic inside the stored procedure as you update the target table. If not, you may just want to LOAD DATA directly into the target table.

For those of you trying to figure out how to actually remove the styling from the element only, without removing the css from the files, this solution works with jquery:

$('.selector').removeAttr('style');

If you are using two DateTime objects, one to store the date the other the time, you could do the following:

var date = new DateTime(2016,6,28);

var time = new DateTime(1,1,1,13,13,13);

var combinedDateTime = date.AddTicks(time.TimeOfDay.Ticks);

An example of this can be found here

[x+1 if x >= 45 else x+5 for x in l]

And for a reward, here is the comment, I wrote to remember this the first time I did this error:

Python's conditional expression is a if C else b and can't be used as:

[a for i in items if C else b]

The right form is:

[a if C else b for i in items]

Even though there is a valid form:

[a for i in items if C]

But that isn't the same as that is how you filter by C, but they can be combined:

[a if tC else b for i in items if fC]

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

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

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

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

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

It works well - you must put unchecked in the checkbox "Enable Just My Code" as highlighted in below image:

You simply need to enclose your SELECT statements in parentheses to indicate that they are subqueries:

SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);

Alternatively, you can use MySQL's SELECT ... INTO syntax. One advantage of this approach is that both cityLat and cityLng can be assigned from a single table-access:

SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;

However, the entire procedure can be replaced with a single self-joined SELECT statement:

SELECT   b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM     cities AS a, cities AS b
WHERE    a.id = cityID
ORDER BY dist
LIMIT    10;

You can hit the key q (for quit) and it should take you to the prompt.

Thanks for @bkurzius's answer and this update is for Charles 3.10+. (The reason is here)

1. Open Charles
2. Go to Proxy > SSL Proxy Settings...
3. Check “Enable SSL Proxying”
4. Select “Add location” and enter the host name and port (if needed)
5. Click ok and make sure the option is checked
6. Go to Help > SSL Proxying > Install Charles Root Certificate on a Mobile Device or Remote Browser..., and just follow the instruction. (use the Android's browser to download and install the certificate.)
7. In “Name the certificate” enter whatever you want
8. Click OK and you should get a message that the certificate was installed

A couple of quick extensions on what has already been said...

An id must be unique, but you can use the same id to make different styles more specific.

For example, given this HTML extract:

<div id="sidebar">
    <h2>Heading</h2>
    <ul class="menu">
        ...
    </ul>
</div>
<div id="content">
    <h2>Heading</h2>
    ...
</div>
<div id="footer">
    <ul class="menu">
        ...
    </ul>
</div>

You could apply different styles with these:

#sidebar h2
{ ... }

#sidebar .menu
{ ... }

#content h2
{ ... }

#footer .menu
{ ... }

Another useful thing to know: you can have multiple classes on an element, by space-delimiting them...

<ul class="main menu">...</ul>
<ul class="other menu">...</ul>

Which allows you to have common styling in .menu with specific styles using .main.menu and .sub.menu

.menu
{ ... }

.main.menu
{ ... }

.other.menu
{ ... }

The format specifers matter: "%s" says that the next string is a narrow string ("ascii" and typically 8 bits per character). "%S" means wide char string. Mixing the two will give "undefined behaviour", which includes printing garbage, just one character or nothing.

One character is printed because wide chars are, for example, 16 bits wide, and the first byte is non-zero, followed by a zero byte -> end of string in narrow strings. This depends on byte-order, in a "big endian" machine, you'd get no string at all, because the first byte is zero, and the next byte contains a non-zero value.

There's many forms of timeout, are you after the connection timeout, request timeout or time to live (time before TCP connection stops).

The default TimeToLive on Firefox is 115s (network.http.keep-alive.timeout)

The default connection timeout on Firefox is 250s (network.http.connection-retry-timeout)

The default request timeout for Firefox is 30s (network.http.pipelining.read-timeout).

The time it takes to do an HttpRequest depends on if a connection has been made this has to be within 250s which I'm guessing you're not after. You're probably after the request timeout which I think is 30,000ms (30s) so to conclude I'd say it's timing out with a connection time out that's why you got a response back after ~150s though I haven't really tested this.

For Mac OS X, save your CSV file in "Windows Comma Separated (.csv)" format.

You are looking for -H option in gnu grep.

find . -name '*bills*' -exec grep -H "put" {} \;

Here is the explanation

    -H, --with-filename
      Print the filename for each match.

.compare() returns an integer, which is a measure of the difference between the two strings.

• A return value of 0 indicates that the two strings compare as equal.
• A positive value means that the compared string is longer, or the first non-matching character is greater.
• A negative value means that the compared string is shorter, or the first non-matching character is lower.

operator== simply returns a boolean, indicating whether the strings are equal or not.

If you don't need the extra detail, you may as well just use ==.

The function takes a pointer to an arbitrary type and returns one such.

You can call a stored procedure using SqlQuery (See here)

// Prepare the query
var query = context.Functions.SqlQuery(
    "EXEC [dbo].[GetFunctionByID] @p1", 
    new SqlParameter("p1", 200));

// add NoTracking() if required

// Fetch the results
var result = query.ToList();

You could use a little javascript to calculate the darker and lighter color using the rgb().

Fiddle : Not really nice, but it is just for illustration.

What it essentially does is sets a color and selects 20 colors with the same amount (compared to one another) of rgb only with 10 apart.

for (var i=-10; i < $('.row:eq(0) .block').length/2 ; i++) {
 var r = 91;
 var g = 192;
 var b = 222;
 $('.row:eq(1) .block:eq('+(i+10)+')').css('background' , color(r+(i*10),g+(i*10),b+   (i*10))      );
};

Now you can do df['column'].dt.date

Note that for datetime objects, if you don't see the hour when they're all 00:00:00, that's not pandas. That's iPython notebook trying to make things look pretty.

These are class stereotypes used in analysis.

• boundary classes are ones at the boundary of the system - the classes that you or other systems interact with

• entity classes classes are your typical business entities like "person" and "bank account"

• control classes implement some business logic or other

Using union will help in this case.

You can also use join on a condition that always returns true and is not related to data in these tables.See below

select tmd .name,tbc.goals from tblMadrid tmd join tblBarcelona tbc on 1=1;

You may want to also look into using Task instead of background workers.

The easiest way to do this is in your example is Task.Run(InitializationThread);.

There are several benefits to using tasks instead of background workers. For example, the new async/await features in .net 4.5 use Task for threading. Here is some documentation about Task https://docs.microsoft.com/en-us/dotnet/api/system.threading.tasks.task

You should check the EOF after reading from file.

fscanf_s                   // read from file
while(condition)           // check EOF
{
   fscanf_s               // read from file
}

i don't see any for loop to initalize the variables.you can do something like this.

for(i=0;i<50;i++){
 /* Code which is necessary with a simple if statement*/

   }

Perfectly described here https://www.smashingmagazine.com/2014/05/moving-git-repository-new-server/

First, we have to fetch all of the remote branches and tags from the existing repository to our local index:

git fetch origin

We can check for any missing branches that we need to create a local copy of:

git branch -a

Let’s use the SSH-cloned URL of our new repository to create a new remote in our existing local repository:

git remote add new-origin [email protected]:manakor/manascope.git

Now we are ready to push all local branches and tags to the new remote named new-origin:

git push --all new-origin 
git push --tags new-origin

Let’s make new-origin the default remote:

git remote rm origin

Rename new-origin to just origin, so that it becomes the default remote:

git remote rename new-origin origin

Would I just override the drawRect method?

Yes:

- (void)drawRect:(CGRect)rect
{
    CGContextRef ctx = UIGraphicsGetCurrentContext();
    CGContextAddEllipseInRect(ctx, rect);
    CGContextSetFillColor(ctx, CGColorGetComponents([[UIColor blueColor] CGColor]));
    CGContextFillPath(ctx);
}

Also, would it be okay to change the frame of that view within the class itself?

Ideally not, but you could.

Or do I need to change the frame from a different class?

I'd let the parent control that.

For those who still can't make this work, make sure that the overflowed element is displayed before using the jQuery function.

Example:

$('#elem').show();
$('#elem').scrollTop(0);

In case you want to hide and show an element, depending on whether it is already visible or not, you can use toggle instead of .hide() and .show()

$('elem').toggle();

If your array is not guaranteed to be populated from index zero, you can use Array.prototype.find():

var elements = []
elements[1] = 'foo'
elements[2] = 'bar'

var first = function(element) { return !!element }    
var gotcha = elements.find(first)

console.log(a[0]) // undefined
console.log(gotcha) // 'foo'

Maybe your solutions works with ints, but It Doesnt work for me with dictionarys.

In one hand, remove() has not worked for me. But maybe it works with basic Types. I guess the code bellow is also the way to remove items from objects list.

In the other hand, 'del' has not worked properly either. In my case, using python 3.6: when I try to delete an element from a list in a 'for' bucle with 'del' command, python changes the index in the process and bucle stops prematurely before time. It only works if You delete element by element in reversed order. In this way you dont change the pending elements array index when you are going through it

Then, Im used:

c = len(list)-1
for element in (reversed(list)):
    if condition(element):
        del list[c]
    c -= 1
print(list)

where 'list' is like [{'key1':value1'},{'key2':value2}, {'key3':value3}, ...]

Also You can do more pythonic using enumerate:

for i, element in enumerate(reversed(list)):
    if condition(element):
        del list[(i+1)*-1]
print(list)

A simple solution is to do this formula:

A1*7+DATE(A2,1,1)

If it returns a Wednesday, simply change the formula to:

(A1*7+DATE(A2,1,1))-2

This will only work for dates within one calendar year.

Pscp.exe is painfully slow.

Uploading files using WinSCP is like 10 times faster.

So, to do that from command line, first you got to add the winscp.com file to your %PATH%. It's not a top-level domain, but an executable .com file, which is located in your WinSCP installation directory.

Then just issue a simple command and your file will be uploaded much faster putty ever could:

WinSCP.com /command "open sftp://username:[email protected]:22" "put your_large_file.zip /var/www/somedirectory/" "exit"

And make sure your check the synchronize folders feature, which is basically what rsync does, so you won't ever want to use pscp.exe again.

WinSCP.com /command "help synchronize"

Read this for detail :

// 1 define a function pointer and initialize to NULL

int (TMyClass::*pt2ConstMember)(float, char, char) const = NULL;

// C++

class TMyClass
{
public:
   int DoIt(float a, char b, char c){ cout << "TMyClass::DoIt"<< endl; return a+b+c;};
   int DoMore(float a, char b, char c) const
         { cout << "TMyClass::DoMore" << endl; return a-b+c; };

   /* more of TMyClass */
};
pt2ConstMember = &TMyClass::DoIt; // note: <pt2Member> may also legally point to &DoMore

// Calling Function using Function Pointer

(*this.*pt2ConstMember)(12, 'a', 'b');

As funny as it may seem, the easiest way I found to save my 180MB spreadsheet into a UTF8 CSV file was to select the cells into Excel, copy them and to paste the content of the clipboard into SublimeText.

The problem is that for reasons of optimization the switch statement in C++ does not work on anything but primitive types, and you can only compare them with compile time constants.

Presumably the reason for the restriction is that the compiler is able to apply some form of optimization compiling the code down to one cmp instruction and a goto where the address is computed based on the value of the argument at runtime. Since branching and and loops don't play nicely with modern CPUs, this can be an important optimization.

To go around this, I am afraid you will have to resort to if statements.

We can use ng-src but when ng-src's value became null, '' or undefined, ng-src will not work. So just use ng-if for this case:

http://jsfiddle.net/Hx7B9/299/

<div ng-app>
    <div ng-controller="AppCtrl"> 
        <a href='#'><img ng-src="{{link}}" ng-if="!!link"/></a>
        <button ng-click="changeLink()">Change Image</button>
    </div>
</div>

This is a little faster (and looks nicer)

np.argmax(aa>5)

Since argmax will stop at the first True ("In case of multiple occurrences of the maximum values, the indices corresponding to the first occurrence are returned.") and doesn't save another list.

In [2]: N = 10000

In [3]: aa = np.arange(-N,N)

In [4]: timeit np.argmax(aa>N/2)
100000 loops, best of 3: 52.3 us per loop

In [5]: timeit np.where(aa>N/2)[0][0]
10000 loops, best of 3: 141 us per loop

In [6]: timeit np.nonzero(aa>N/2)[0][0]
10000 loops, best of 3: 142 us per loop

If you are using Matplotlib and are trying to get good figures in a LaTeX document, save as an EPS. Specifically, try something like this after running the commands to plot the image:

plt.savefig('destination_path.eps', format='eps')

I have found that EPS files work best and the dpi parameter is what really makes them look good in a document.

To specify the orientation of the figure before saving, simply call the following before the plt.savefig call, but after creating the plot (assuming you have plotted using an axes with the name ax):

ax.view_init(elev=elevation_angle, azim=azimuthal_angle)

Where elevation_angle is a number (in degrees) specifying the polar angle (down from vertical z axis) and the azimuthal_angle specifies the azimuthal angle (around the z axis).

I find that it is easiest to determine these values by first plotting the image and then rotating it and watching the current values of the angles appear towards the bottom of the window just below the actual plot. Keep in mind that the x, y, z, positions appear by default, but they are replaced with the two angles when you start to click+drag+rotate the image.

If you are using a third party library called apache commons-lang, the following solution can be useful:

Use StringUtils class of apache commons-lang :

int i = 5;
StringUtils.leftPad(String.valueOf(i), 3, "0"); // --> "005"

As StringUtils.leftPad() is faster than String.format()

What Arne said - you can't reliably style select boxes and have them look anything like consistent across browsers.

Uniform: https://github.com/pixelmatrix/uniform is a javascript solution which gives you good graphic control over your form elements - it's still Javascript, but it's about as nice as javascript gets for solving this problem.

It means you're passing the variable by reference.

In fact, in a declaration of a type, it means reference, just like:

int x = 42;
int& y = x;

declares a reference to x, called y.

There are 3 ways to pass data from Parent to Children

1. Through shareable service : you should store into a service the data you would like to share with the children

2. Through Children Router Resolver if you have to receive different data

   this.data = this.route.snaphsot.data['dataFromResolver'];
   

3. Through Parent Router Resolver if your have to receive the same data from parent

   this.data = this.route.parent.snaphsot.data['dataFromResolver'];
   

Note1: You can read about resolver here. There is also an example of resolver and how to register the resolver into the module and then retrieve data from resolver into the component. The resolver registration is the same on the parent and child.

Note2: You can read about ActivatedRoute here to be able to get data from router

Deadlock is a common problem in multiprocessing/multiprogramming problems in OS. Say there are two processes P1, P2 and two globally shareable resource R1, R2 and in critical section both resources need to be accessed

Initially, the OS assigns R1 to process P1 and R2 to process P2. As both processes are running concurrently they may start executing their code but the PROBLEM arises when a process hits the critical section. So process R1 will wait for process P2 to release R2 and vice versa... So they will wait for forever (DEADLOCK CONDITION).

A small ANALOGY...

Your Mother(OS),
You(P1),
Your brother(P2),
Apple(R1),
Knife(R2),
critical section(cutting apple with knife).

Your mother gives you the apple and the knife to your brother in the beginning.
Both are happy and playing(Executing their codes).
Anyone of you wants to cut the apple(critical section) at some point.
You don't want to give the apple to your brother.
Your brother doesn't want to give the knife to you.
So both of you are going to wait for a long very long time :)

I use a trigger as a workaround to set a datetime field to NOW() for new inserts:

CREATE TRIGGER `triggername` BEFORE INSERT ON  `tablename` 
FOR EACH ROW 
SET NEW.datetimefield = NOW()

it should work for updates too

Answers by Johan & Leonardo involve converting to a timestamp field. Although this is probably ok for the use case presented in the question (storing RegisterDate and LastVisitDate), it is not a universal solution. See datetime vs timestamp question.

RewriteCond %{HTTP_HOST} ^!example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

This starts with the HTTP_HOST variable, which contains just the domain name portion of the incoming URL (example.com). Assuming the domain name does not contain a www. and matches your domain name exactly, then the RewriteRule comes into play. The pattern ^(.*)$ will match everything in the REQUEST_URI, which is the resource requested in the HTTP request (foo/blah/index.html). It stores this in a back reference, which is then used to rewrite the URL with the new domain name (one that starts with www).

[NC] indicates case-insensitive pattern matching, [R=301] indicates an external redirect using code 301 (resource moved permanently), and [L] stops all further rewriting, and redirects immediately.

Best settings for Sublime Text 3 as your Git editor (Windows & Linux instructions):

To follow these instructions in Windows make sure you have installed Git for Windows. In Windows, I like to use Git Bash so that it feels more like Linux.

First, we want to create a special Sublime Text project so that we can specify special project settings we want set whenever Git calls the editor, to make things easier when editing in Git. For example, I normally set my ruler to 120 chars in most projects, but for Git commit messages I want it to be 72 characters so that it fits nicely in a terminal when you call git log or git lg.

1. Create a Sublime Text project with settings we want to use to edit Git commit messages

Open Sublime Text and go to menu "File" ? "New Window" to create a new anonymous project. Go to menu "Project" ? "Save Project As..." and choose a place to save it. In Linux I saved it in my Linux home directory with the file name .gitconfig.sublime-project. Its path is therefore: ~/.gitconfig.sublime-project. In Windows also save it in your home directory, for example: C:\Users\MY_USER_NAME\.gitconfig.sublime-project Now go to menu "Project" ? "Edit Project" to edit the project settings. Paste the following and save the settings. Make any further edits for your project settings if desired.

{
    // For folder settings help see here: https://www.sublimetext.com/docs/3/projects.html

    "folders":
    [

    ],

    "settings":
    {

        // Disables horizontal scrolling if enabled.
        // May be set to true, false, or "auto", where it will be disabled for
        // source code, and otherwise enabled.
        "word_wrap": false,

        // Set to a value other than 0 to force wrapping at that column rather than the
        // window width
        "wrap_width": 0,

        // Columns in which to display vertical rulers
        "rulers": [72, 50], //72 is recommended by git for commit message content, and 50 for commit titles

        // The number of spaces a tab is considered equal to
        "tab_size": 4,

        // Set to true to insert spaces when tab is pressed
        "translate_tabs_to_spaces": true,
    },

    "build_systems":
    [

    ]

}

2. Set the editor to be used by Git

Now we need to set the editor to be used by Git, by editing the .gitconfig file.

For Linux:

Your user copy of this will be located in ~/.gitconfig. Open this file and add the following lines. Be sure to use the proper path name to the Git project you just created above! I'm using ~/.gitconfig.sublime-project.

[core]
    editor = subl --project ~/.gitconfig.sublime-project --wait

The --wait is important, as it forces Git to wait until you close the file before it continues on. The --project line is important to tell Sublime Text which project you want opened whenever Git opens Sublime Text.

Per @digitaldreamer's answer above (https://stackoverflow.com/a/2596835/4561887), "subl can be replaced by the full path of the executable but [the alias subl] is usually available when [Sublime is] correctly installed."

For Windows:

For Windows, first read the Linux instructions for background information. Now we will do something almost identical.

(OPTIONAL: create a subl alias for use in Git Bash):

Open up a text editor (for example, Notepad, Notepad++, Sublime Text, Geany, etc.), and create a file called ".bash_profile" in your home directory. Its path will therefore be: C:\Users\MY_USER_NAME\.bash_profile. Save the following into it:

alias subl="/c/Program\ Files/Sublime\ Text\ 3/subl.exe"

This creates a Git Bash alias called subl that we can now use in Git Bash for Windows, to easily open Sublime Text. This step isn't required, but it's useful for general Git Bash use. Now you can call subl ., for instance, in Git Bash to open up a new Sublime Text project in your current directory.

(MANDATORY):

Edit the .gitconfig file found in your home directory: C:\Users\MY_USER_NAME\.gitconfig, by adding the following to it. Notice the subtle changes from the Linux instructions above:

[core]
  editor = 'C:/Program Files/Sublime Text 3/subl.exe' --project ~/.gitconfig.sublime-project --wait

• Notice that you must specify the full path to the Sublime Text executable. Note the direction of the slashes! Use / NOT \ to separate folders in the path name! (Thanks VonC for helping me see this).
• Our subl alias we made for Git Bash above doesn't work here, so you can't use it like we did in the Linux example, instead you must specify the whole path as shown above.
• The ~ symbol, however, does still work here to get to your Windows home directory.

2.5. (Optional) Install the "Git" package into Sublime Text 3.

This gives you syntax highlighting for git commit messages, as well as access to other Git commands such as git blame (which I use frequently in Sublime Text) or git commit (which I don't use in Sublime Text since I'd prefer the command-line for general Git flow, as I've mentioned in my comments below this answer).

To install a package: First, ensure “Package Control” is installed. Next, press Ctrl + Shift + P (same as Tools ? Command Palette) and type all or part of “Package Control: Install Package”, then press Enter. In the search box that comes up, search for the package "Git" and hit Enter on it, or click on it, to automatically install it.

Once installed, Ctrl + Shift + P then searching for "git" will bring up Git commands you can use internally inside Sublime Text now, such as git blame.

3. Use it

Now when you call git commit, for instance, as normal from the command-line, Sublime Text will open up into the .gitconfig.sublime-project we created above, with that project's settings! As you type a paragraph you'll notice it extends past the ruler we set since soft word-wrap is off. To force hard wrap via auto-inserted hard-returns at the end of each line, put your cursor on the long line you want auto-wrapped and press Alt + Q. It will now hard-wrap/hard-fold at 72 characters, which is what we set in the project settings' "rulers" parameter above.

Now, save your commit message with Ctrl + S, and exit (to complete your git commit) with Ctrl + Shift + W.

Done!

Not yet, but the New NIO (JSR 203) will have support for these common operations.

In the meantime, there are a few things to keep in mind.

File.renameTo generally works only on the same file system volume. I think of this as the equivalent to a "mv" command. Use it if you can, but for general copy and move support, you'll need to have a fallback.

When a rename doesn't work you will need to actually copy the file (deleting the original with File.delete if it's a "move" operation). To do this with the greatest efficiency, use the FileChannel.transferTo or FileChannel.transferFrom methods. The implementation is platform specific, but in general, when copying from one file to another, implementations avoid transporting data back and forth between kernel and user space, yielding a big boost in efficiency.

If you're on a page and this does not work:

$page_object = get_queried_object();
$page_id     = get_queried_object_id();

you can try to build the permalink manually with PHP so you can lookup the post ID:

// get or make permalink
$url = !empty(get_the_permalink()) ? get_the_permalink() : (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$permalink = strtok($url, '?');

// get post_id using url/permalink
$post_id = url_to_postid($url);

// want the post or postmeta? use get_post() or get_post_meta()
$post = get_post($post_id);
$postmeta = get_post_meta($post_id);

It may not catch every possible permalink (especially since I'm stripping out the query string), but you can modify it to fit your use case.

That is okay for removing of data connections by using VBA as follows:

Sub deleteConn()
    Dim xlBook As Workbook
    Dim Cn As WorkbookConnection
    Dim xlSheet As Worksheet
    Dim Qt As QueryTable
    Set xlBook = ActiveWorkbook
    For Each Cn In xlBook.Connections
        Debug.Print VarType(Cn)
        Cn.Delete
    Next Cn
    For Each xlSheet In xlBook.Worksheets
        For Each Qt In xlSheet.QueryTables
            Debug.Print Qt.Name
            Qt.Delete
        Next Qt
    Next xlSheet
End Sub

The preferred approach should be:

Double.valueOf(d).longValue()

From the Double (Java Platform SE 7) documentation:

Double.valueOf(d)

Returns a Double instance representing the specified double value. If a new Double instance is not required, this method should generally be used in preference to the constructor Double(double), as this method is likely to yield significantly better space and time performance by caching frequently requested values.

public IList<Splitting> get(Guid companyId, long customrId) {    
    var res=from c in Customers_data_source
            where c.CustomerId = customrId && c.CompanyID == companyId
            from s in Splittings_data_srouce
            where s.CustomerID = c.CustomerID
            select s;

    return res.ToList();
}

So, when using gcc, I like:

#define DBGI(expr) ({int g2rE3=expr; fprintf(stderr, "%s:%d:%s(): ""%s->%i\n", __FILE__,  __LINE__, __func__, #expr, g2rE3); g2rE3;})

Because it can be inserted into code.

Suppose you're trying to debug

printf("%i\n", (1*2*3*4*5*6));

720

Then you can change it to:

printf("%i\n", DBGI(1*2*3*4*5*6));

hello.c:86:main(): 1*2*3*4*5*6->720
720

And you can get an analysis of what expression was evaluated to what.

It's protected against the double-evaluation problem, but the absence of gensyms does leave it open to name-collisions.

However it does nest:

DBGI(printf("%i\n", DBGI(1*2*3*4*5*6)));

hello.c:86:main(): 1*2*3*4*5*6->720
720
hello.c:86:main(): printf("%i\n", DBGI(1*2*3*4*5*6))->4

So I think that as long as you avoid using g2rE3 as a variable name, you'll be OK.

Certainly I've found it (and allied versions for strings, and versions for debug levels etc) invaluable.
