The answer you selected is fine, and it works, but it isn't the correct way to do it, because:

grep -nr yourString* .

This actually searches the string "yourStrin" and "g" 0 or many times.

So the proper way to do it is:

grep -nr \w*yourString\w* .

This command searches the string with any character before and after on the current folder.

I don't think you need/want the timeout.

onhover (hover) would be defined as the time period while "over" something. IMHO

onmouseover = start...

onmouseout = ...end

For the record I've done some stuff with this to "fake" the hover event in IE6. It was rather expensive and in the end I ditched it in favor of performance.

dataGridView1.Rows[i].Cells[7].Style.BackColor = Color.LightGreen;

The only real difference is that a synchronized block can choose which object it synchronizes on. A synchronized method can only use 'this' (or the corresponding Class instance for a synchronized class method). For example, these are semantically equivalent:

synchronized void foo() {
  ...
}

void foo() {
    synchronized (this) {
      ...
    }
}

The latter is more flexible since it can compete for the associated lock of any object, often a member variable. It's also more granular because you could have concurrent code executing before and after the block but still within the method. Of course, you could just as easily use a synchronized method by refactoring the concurrent code into separate non-synchronized methods. Use whichever makes the code more comprehensible.

try this one out resizeable button

<button type="submit me" style="height: 25px; width: 100px">submit me</button>

A slight more difficult answer that uses ControlTemplate and has an animation effect (adapted from https://docs.microsoft.com/en-us/dotnet/framework/wpf/controls/customizing-the-appearance-of-an-existing-control)

In your resource dictionary define a control template for your button like this one:

<ControlTemplate TargetType="Button" x:Key="testButtonTemplate2">
    <Border Name="RootElement">
        <Border.Background>
            <SolidColorBrush x:Name="BorderBrush" Color="Black"/>
        </Border.Background>

        <Grid Margin="4" >
            <Grid.Background>
                <SolidColorBrush x:Name="ButtonBackground" Color="Aquamarine"/>
            </Grid.Background>
            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="4,5,4,4"/>
        </Grid>
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="CommonStates">
                <VisualState x:Name="Normal"/>
                <VisualState x:Name="MouseOver">
                    <Storyboard>
                        <ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
                    </Storyboard>
                </VisualState>
                <VisualState x:Name="Pressed">
                    <Storyboard>
                        <ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
                    </Storyboard>
                </VisualState>
            </VisualStateGroup>
        </VisualStateManager.VisualStateGroups>
    </Border>
</ControlTemplate>

in your XAML you can use the template above for your button as below:

Define your button

<Button Template="{StaticResource testButtonTemplate2}" 
HorizontalAlignment="Center" VerticalAlignment="Center" 
Foreground="White">My button</Button>

Hope it helps

Unfortunately Java does not make String implement Iterable<Character>. This could easily be done. There is StringCharacterIterator but that doesn't even implement Iterator... So make your own:

public class CharSequenceCharacterIterable implements Iterable<Character> {
    private CharSequence cs;

    public CharSequenceCharacterIterable(CharSequence cs) {
        this.cs = cs;
    }

    @Override
    public Iterator<Character> iterator() {
        return new Iterator<Character>() {
            private int index = 0;

            @Override
            public boolean hasNext() {
                return index < cs.length();
            }

            @Override
            public Character next() {
                return cs.charAt(index++);
            }
        };
    }
}

Now you can (somewhat) easily run for (char c : new CharSequenceCharacterIterable("xyz"))...

can use this to redirect

echo '<meta http-equiv="refresh" content="1; URL=index.php" />';

the content=1 can be change to different value to increase the delay before redirection

Following code gives intended results.

string text="some interesting text\nsome text that should be in the same line\r\nsome 
text should be in another line"
var results = text.Split(new[] {"\n","\r\n"}, StringSplitOptions.None);

Here's two simple examples

> x <- letters[1:4]
> replace(x, 3, 'Z') #replacing 'c' by 'Z'
[1] "a" "b" "Z" "d"
> 
> y <- 1:10
> replace(y, c(4,5), c(20,30)) # replacing 4th and 5th elements by 20 and 30
 [1]  1  2  3 20 30  6  7  8  9 10

Your regex seems a bit too complex in my opinion. Also, remember that the dot is a special character meaning "any character". The following regex should work (note the escaped dots):

^.*\.(jpg|JPG|gif|GIF|doc|DOC|pdf|PDF)$

You can use a tool like Expresso to test your regular expressions.

Here is how you do in Eloquent

$users = User::whereIn('id', array(1, 2, 3))->get();

And if you are using Query builder then :

$users = DB::table('users')->whereIn('id', array(1, 2, 3))->get();

You can accomplish this using the function FILL to create filled polygons under the sections of your plots. You will want to plot the lines and polygons in the order you want them to be stacked on the screen, starting with the bottom-most one. Here's an example with some sample data:

x = 1:100;             %# X range
y1 = rand(1,100)+1.5;  %# One set of data ranging from 1.5 to 2.5
y2 = rand(1,100)+0.5;  %# Another set of data ranging from 0.5 to 1.5
baseLine = 0.2;        %# Baseline value for filling under the curves
index = 30:70;         %# Indices of points to fill under

plot(x,y1,'b');                              %# Plot the first line
hold on;                                     %# Add to the plot
h1 = fill(x(index([1 1:end end])),...        %# Plot the first filled polygon
          [baseLine y1(index) baseLine],...
          'b','EdgeColor','none');
plot(x,y2,'g');                              %# Plot the second line
h2 = fill(x(index([1 1:end end])),...        %# Plot the second filled polygon
          [baseLine y2(index) baseLine],...
          'g','EdgeColor','none');
plot(x(index),baseLine.*ones(size(index)),'r');  %# Plot the red line

And here's the resulting figure:

You can also change the stacking order of the objects in the figure after you've plotted them by modifying the order of handles in the 'Children' property of the axes object. For example, this code reverses the stacking order, hiding the green polygon behind the blue polygon:

kids = get(gca,'Children');        %# Get the child object handles
set(gca,'Children',flipud(kids));  %# Set them to the reverse order

Finally, if you don't know exactly what order you want to stack your polygons ahead of time (i.e. either one could be the smaller polygon, which you probably want on top), then you could adjust the 'FaceAlpha' property so that one or both polygons will appear partially transparent and show the other beneath it. For example, the following will make the green polygon partially transparent:

set(h2,'FaceAlpha',0.5);

Children inherit opacity. It'd be weird and inconvenient if they didn't.

You can use a translucent PNG file for your background image, or use an RGBa (a for alpha) color for your background color.

Example, 50% faded black background:

<div style="background-color:rgba(0, 0, 0, 0.5);">_x000D_
   <div>_x000D_
      Text added._x000D_
   </div>_x000D_
</div>

You said you didn't want to use a translucent Activity, but that seems to be the best way to do this:

1. In your Manifest, set the Activity theme to Theme.Translucent.NoTitleBar.
2. Don't bother with a layout for your Activity, and don't call setContentView().
3. In your Activity's onCreate(), start your Service with startService().
4. Exit the Activity with finish() once you've started the Service.

In other words, your Activity doesn't have to be visible; it can simply make sure your Service is running and then exit, which sounds like what you want.

I would highly recommend showing at least a Toast notification indicating to the user that you are launching the Service, or that it is already running. It is very bad user experience to have a launcher icon that appears to do nothing when you press it.

If these are folders you want to ignore in a certain workspace, you can go to:

AppMenu > Preferences > Workspace Settings

Otherwise, if you want these folders to be ignored in all your workspaces, go to:

AppMenu > Preferences > User Settings

and add the following to your configuration:

//-------- Search configuration --------

// The folders to exclude when doing a full text search in the workspace.
"search.excludeFolders": [
    ".git",
    "node_modules",
    "bower_components",
    "path/to/other/folder/to/exclude"
],

The difference between workspace and user settings is explained in the customization docs

for bootstrap 4 documentation

  <div class="row justify-content-end">
    <div class="col-4">
      Start of the row
    </div>
    <div class="col-4">
      End of the row
    </div>
  </div>

This answer is very late but what I do is set a class that holds Booleans, arrays, and integer-initial values as global scope static variables. Any constant strings are defined as such.

define("myconstant", "value"); 

class globalVars {

    static $a = false;

    static $b = 0;

    static $c = array('first' => 2, 'second' => 5);

}


function test($num) {

    if (!globalVars::$a) {

        $returnVal = 'The ' . myconstant . ' of ' . $num . ' plus ' . globalVars::$b . ' plus ' . globalVars::$c['second'] . ' is ' . ($num + globalVars::$b + globalVars::$c['second']) . '.';

        globalVars::$a = true;

    } else {

        $returnVal = 'I forgot';

    }

    return $returnVal;

}

echo test(9); ---> The value of 9 + 0 + 5 is 14.

echo "<br>";

echo globalVars::$a; ----> 1

The static keywords must be present in the class else the vars $a, $b, and $c will not be globally scoped.

The SSL certificates are going to be bound to hostname rather than IP if they are setup in the standard way. Hence why it works at one site rather than the other.

Even if the servers share the same hostname they may well have two different certificates and hence WebSphere will have a certificate trust issue as it won't be able to recognise the certificate on the second server as it is different to the first.

As this is tagged with the extjs tag it may be worth looking at the extjs method: http://docs.sencha.com/extjs/6.2.0/classic/Ext.Function.html#method-interval

This works much like setInterval, but also takes care of the scope, and allows arguments to be passed too:

function setBgPosition() {
    var c = 0;
    var numbers = [0, -120, -240, -360, -480, -600, -720];
    function run() {
       Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
        if (c<numbers.length){
            c=0;
        }
    }
    return Ext.Function.interval(run,200);
}

var bgPositionTimer = setBgPosition();

when you want to stop you can use clearInterval to stop it

clearInterval(bgPositionTimer);

An example use case would be:

Ext.Ajax.request({
    url: 'example.json',

    success: function(response, opts) {
        clearInterval(bgPositionTimer);
    },

    failure: function(response, opts) {
        console.log('server-side failure with status code ' + response.status);
        clearInterval(bgPositionTimer);
    }
});

Hi I add key and value to each object

let persons = [_x000D_
  {_x000D_
    name : "John Doe Sr",_x000D_
    age: 30_x000D_
  },{_x000D_
    name: "John Doe Jr",_x000D_
    age : 5_x000D_
  }_x000D_
]_x000D_
_x000D_
function addKeyValue(obj, key, data){_x000D_
  obj[key] = data;_x000D_
}_x000D_
 _x000D_
_x000D_
let newinfo = persons.map(function(person) {_x000D_
  return addKeyValue(person, 'newKey', 'newValue');_x000D_
});_x000D_
_x000D_
console.log(persons);

I finally got it:

ObjectMapper objectMapper = new ObjectMapper();
TypeFactory typeFactory = objectMapper.getTypeFactory();
List<SomeClass> someClassList = objectMapper.readValue(jsonString, typeFactory.constructCollectionType(List.class, SomeClass.class));

I use this to get the Parent, similarly for child

$( this ).children( 'li.target' ).css("border", "3px double red");

Good Luck

I would use these polyfill https://github.com/WebReflection/ie8

I was having a similar problem to @Batman. However, because I was running this under /usr/local/src/projectname, running without sudo was not an option.

Just add the -E flag to preseve the environment (your ~/.ssh/ path).

$ sudo -E git clone git@your_repo

From man sudo:

-E, --preserve-env Indicates to the security policy that the user wishes to pre- serve their existing environment variables. The security policy may return an error if the user does not have permis- sion to preserve the environment.

You could also have a union of the blank select with the select that has content:

select '' value, '' name
union
select value, name from mytable

I created a JsFiddle here based on the answer given by Zachary. It provides a more accessible user interface and also escapes double quotes within strings properly.

I created a single node k8s cluster using kubeadm. When i tried PortForward and kubectl proxy, it showed external IP as pending.

$ kubectl get svc -n argocd argocd-server
NAME            TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                      AGE
argocd-server   LoadBalancer   10.107.37.153   <pending>     80:30047/TCP,443:31307/TCP   110s

In my case I've patched the service like this:

kubectl patch svc <svc-name> -n <namespace> -p '{"spec": {"type": "LoadBalancer", "externalIPs":["172.31.71.218"]}}'

After this, it started serving over the public IP

$ kubectl get svc argo-ui -n argo
NAME      TYPE           CLUSTER-IP     EXTERNAL-IP     PORT(S)        AGE
argo-ui   LoadBalancer   10.103.219.8   172.31.71.218   80:30981/TCP   7m50s

This worked for me.

Locate config.sample.inc.php

Change

$cfg['Servers'][$i]['host'] = 'localhost';

into

$cfg['Servers'][$i]['host'] = '127.0.0.1';

Save.

Then rename the file and remove sample from the name.

Note: please update the date format accordingly.

Format Date

   __formatDate: function(myDate){
      var ts = moment.utc(myDate);
      return ts.local().format('D-MMM-Y');
   }

Format Time

  __formatTime: function(myDate){
      var ts = moment.utc(myDate);
      return ts.local().format('HH:mm');
  },

You could also use negative margins:

.column {_x000D_
  float: left;_x000D_
  overflow: hidden;_x000D_
  width: 120px;_x000D_
}_x000D_
.cell {_x000D_
  border: 1px solid red;_x000D_
  width: 120px;_x000D_
  height: 20px;_x000D_
  box-sizing: border-box;_x000D_
}_x000D_
.cell:not(:first-child) {_x000D_
  margin-top: -1px;_x000D_
}_x000D_
.column:not(:first-child) > .cell {_x000D_
  margin-left: -1px;_x000D_
}

<div class="container">_x000D_
  <div class="column">_x000D_
    <div class="cell"></div>_x000D_
    <div class="cell"></div>_x000D_
    <div class="cell"></div>_x000D_

You can actually have all the code in the aspx page. As explained here.

Sample from here:

<%@ Language=C# %>
<HTML>
   <script runat="server" language="C#">
   void MyButton_OnClick(Object sender, EventArgs e)
   {
      MyLabel.Text = MyTextbox.Text.ToString();
   }
   </script>
   <body>
      <form id="MyForm" runat="server">
         <asp:textbox id="MyTextbox" text="Hello World" runat="server"></asp:textbox>
         <asp:button id="MyButton" text="Echo Input" OnClick="MyButton_OnClick" runat="server"></asp:button>
         <asp:label id="MyLabel" runat="server"></asp:label>
      </form>

If you want to build a different configuration without regenerating if using you can also run cmake --build {$PWD} --config <cfg> For multi-configuration tools, choose <cfg> ex. Debug, Release, MinSizeRel, RelWithDebInfo

I got this issue because of a rather silly mistake. I had forgotten to hook my service configuration procedure to discover controllers automatically in the ASP.NET Core application.

Adding this method solved it:

// Add framework services.
            services.AddMvc()
                    .AddControllersAsServices();      // <---- Super important

Here is a working example with Angular version 2.3. Just call the constructor of the service the stand way like this constructor(private _userService:UserService) . And it will create a singleton for the app.

user.service.ts

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Rx';
import { Subject }    from 'rxjs/Subject';
import { User } from '../object/user';


@Injectable()
export class UserService {
    private userChangedSource;
    public observableEvents;
    loggedUser:User;

    constructor() {
       this.userChangedSource = new Subject<any>();
       this.observableEvents = this.userChangedSource.asObservable();
    }

    userLoggedIn(user:User) {
        this.loggedUser = user;
        this.userChangedSource.next(user);
    }

    ...
}

app.component.ts

import { Component } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { UserService } from '../service/user.service';
import { User } from '../object/user';

@Component({
    selector: 'myApp',
    templateUrl: './app.component.html'
})
export class AppComponent implements OnInit {
    loggedUser:User;

    constructor(private _userService:UserService) { 
        this._userService.observableEvents.subscribe(user => {
                this.loggedUser = user;
                console.log("event triggered");
        });
    }
    ...
}

Try this its working..

    <script>
      $(function () {
          $('form').on('submit', function (e) {
              e.preventDefault();
              $.ajax({
                  type: 'post',
                  url: '<?php echo base_url();?>student_ajax/insert',
                  data: $('form').serialize(),
                  success: function (response) {
                      alert('form was submitted');
                  }
                  error:function() {
                      alert('fail');
                  }
              });
          });
      });
    </script>

using System.Windows.Forms;
...
MessageBox.Show("Hello World!");

You have to loop through every cell in the range "D3:D6" and construct your To string. Simply assigning it to a variant will not solve the purpose. EmailTo becomes an array if you assign the range directly to it. You can do this as well but then you will have to loop through the array to create your To string

Is this what you are trying? (TRIED AND TESTED)

Open ES explorer -> push Menu button at the left upper corner (three horizontal stripes) -> in the Libraries section choose APPs.

Thus, you get the list of all the user apps. Find your app and select it with long pushing on it. Then press "More" in the right low corner and choose "Send". Then you can use different options, e.g. you can choose "ES Save To" in order to save the .apk file to your home directory or anywhere else.

You mentioned that you want the regex to match each of those strings, yet you previously mention that the is 1-2 digits before the decimal?

This will match 1-2 digits followed by a possible decimal, followed by another 1-2 digits but FAIL on your example of .33

\d{1,2}\.?\d{1,2}

This will match 0-2 digits followed by a possible deciaml, followed by another 1-2 digits and match on your example of .33

\d{0,2}\.?\d{1,2}

Not sure exactly which one you're looking for.

select just changes cardinality of the result table but project does change both degree of relation and cardinality.

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

Really a PITA this is not part of standard Javascript.

/**
 * Iterates the keys and values of an object.  Object.keys is used to extract the keys.
 * @param object The object to iterate
 * @param fn (value,key)=>{}
 */
function objectForEach(object, fn) {
    Object.keys(object).forEach(key => {
        fn(object[key],key, object)
    })
}

Note: I switched the callback parameters to (value,key) and added a third object to make the API consistent other APIs.

Use it like this

const o = {a:1, b:true};
objectForEach(o, (value, key, obj)=>{
    // do something
});

You can use window.open to open a new window/tab(according to browser setting) in javascript.

By using document.write you can write HTML content to the opened window.

EDIT: I'm getting a lot of downvotes on this recently...so I thought I'd just add a note that this answer was written before the question underwent it's most recent edit, where returning null was highlighted as an option...which seems very acceptable. Some of my answer was addressed to concerns like that of Edwardo, in the comments, who seemed to be advocating returning a 0. This is the case I was railing against.

ANSWER: I think there's an underlying issue here, which is that division by 0 is not legal. It's an indication that something is fundementally wrong. If you're dividing by zero, you're trying to do something that doesn't make sense mathematically, so no numeric answer you can get will be valid. (Use of null in this case is reasonable, as it is not a value that will be used in later mathematical calculations).

So Edwardo asks in the comments "what if the user puts in a 0?", and he advocates that it should be okay to get a 0 in return. If the user puts zero in the amount, and you want 0 returned when they do that, then you should put in code at the business rules level to catch that value and return 0...not have some special case where division by 0 = 0.

That's a subtle difference, but it's important...because the next time someone calls your function and expects it to do the right thing, and it does something funky that isn't mathematically correct, but just handles the particular edge case it's got a good chance of biting someone later. You're not really dividing by 0...you're just returning an bad answer to a bad question.

Imagine I'm coding something, and I screw it up. I should be reading in a radiation measurement scaling value, but in a strange edge case I didn't anticipate, I read in 0. I then drop my value into your function...you return me a 0! Hurray, no radiation! Except it's really there and it's just that I was passing in a bad value...but I have no idea. I want division to throw the error because it's the flag that something is wrong.

this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.

for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.

PS: but like I said, this might be totally unrelated to your query :)

I was facing this issue, then I put my dropdown in nav tag. Worked for me that way.

Actually the _var convention comes from VB not C# or C++ (m_,... is another thing).

This came to overcome the case insensitivity of VB when declaring Properties.

For example, such code isn't possible in VB because it considers user and User as the same identifier

Private user As String

Public Property User As String
  Get
    Return user
  End Get
  Set(ByVal Value As String)
    user = value
  End Set
End Property

So to overcome this, some used a convention to add '_' to the private field to come like this

Private _user As String

Public Property User As String
  Get
    Return _user
  End Get
  Set(ByVal Value As String)
    _user = value
  End Set
End Property

Since many conventions are for .Net and to keep some uniformity between C# et VB.NET convention, they are using the same one.

I found the reference for what I was saying : http://10rem.net/articles/net-naming-conventions-and-programming-standards---best-practices

Camel Case with Leading Underscore. In VB.NET, always indicate "Protected" or "Private", do not use "Dim". Use of "m_" is discouraged, as is use of a variable name that differs from the property by only case, especially with protected variables as that violates compliance, and will make your life a pain if you program in VB.NET, as you would have to name your members something different from the accessor/mutator properties. Of all the items here, the leading underscore is really the only controversial one. I personally prefer it over straight underscore-less camel case for my private variables so that I don't have to qualify variable names with "this." to distinguish from parameters in constructors or elsewhere where I likely will have a naming collision. With VB.NET's case insensitivity, this is even more important as your accessor properties will usually have the same name as your private member variables except for the underscore. As far as m_ goes, it is really just about aesthetics. I (and many others) find m_ ugly, as it looks like there is a hole in the variable name. It's almost offensive. I used to use it in VB6 all the time, but that was only because variables could not have a leading underscore. I couldn't be happier to see it go away. Microsoft recommends against the m_ (and the straight _) even though they did both in their code. Also, prefixing with a straight "m" is right out. Of course, since they code mainly in C#, they can have private members that differ only in case from the properties. VB folks have to do something else. Rather than try and come up with language-by-language special cases, I recommend the leading underscore for all languages that will support it. If I want my class to be fully CLS-compliant, I could leave off the prefix on any C# protected member variables. In practice, however, I never worry about this as I keep all potentially protected member variables private, and supply protected accessors and mutators instead. Why: In a nutshell, this convention is simple (one character), easy to read (your eye is not distracted by other leading characters), and successfully avoids naming collisions with procedure-level variables and class-level properties.class-level properties.

In web.config under

<system.webServer>

replace (or add) the line

<httpErrors errorMode="Detailed"></httpErrors>

with

<httpErrors existingResponse="PassThrough" errorMode="Detailed"></httpErrors>

This is because by default IIS7 intercepts HTTP status codes such as 4xx and 5xx generated by applications further up the pipeline.

Next, enable "Send Errors to Browser" under the "ASP" section, and under "Error Pages / Edit Feature Settings", select "Detailed errors".

Also, give Write permissions on the website folder to the IIS_IUSRS builtin group.

if ( $('#myfav').children().length > 0 ) {
     // do something
}

This should work. The children() function returns a JQuery object that contains the children. So you just need to check the size and see if it has at least one child.

just make it function,

<script type="text/javascript">
function AlertIt() {
var answer = confirm ("Please click on OK to continue.")
if (answer)
window.location="http://www.continue.com";
}
</script>

<a href="javascript:AlertIt();">click me</a>

Few answers that may be useful, especially if you have dynamic content.

$('#dialogueForm').live("dialogclose", function(){
   //your code to run on dialog close
});

Or, when opening the modal, have a callback.

$( "#dialogueForm" ).dialog({
              autoOpen: false,
              height: "auto",
              width: "auto",
              modal: true,
                my: "center",
                at: "center",
                of: window,
              close : function(){
                  // functionality goes here
              }  
              });

Here is a nice plugin for jQuery that submits forms via ajax:

http://malsup.com/jquery/form/

its as simple as:

<script src="http://malsup.github.com/jquery.form.js"></script> 
<script> 
    $(document).ready(function() { 
        $('#myForm').ajaxForm(function() { 
           alert('form was submitted');
        }); 
    }); 
</script> 

It uses the forms action for the post location. Not that you can't achieve this with your own code but this plugin has worked very nicely for me!

You can, in Java 10, but only for Local variables, meaning,

You can,

var anum = 10; var aString = "Var";

But can't,

var anull = null; // Since the type can't be inferred in this case

Check out the spec for more info.

Note that if there are ties in top 10 values, you will only get the top 10 rows, not the top 10 values with the answers provided. Ex: if the top 5 values are 10, 11, 12, 13, 14, 15 but your data contains 10, 10, 11, 12, 13, 14, 15 you will only get 10, 10, 11, 12, 13, 14 as your top 5 with a LIMIT

Here is a solution which will return more than 10 rows if there are ties but you will get all the rows where some_value_column is technically in the top 10.

select
  *
from
  (select
     *,
     rank() over (order by some_value_column desc) as my_rank
  from mytable) subquery

Since ViewPager is tending to be replaced by ViewPager2 and we will need to migrate to it.

A quick work around using Java would be something like this:

    final List<String> colors = new ArrayList<String>(){
        {
            add("#FF0000");
            add("#800000");
            add("#FFFF00");
        }
    };

    
    ViewPager2 viewPager = findViewById(R.id.viewPager);
    ViewPagerAdapter adapter = new ViewPagerAdapter(your_data_structure);
    viewPager.setAdapter(adapter);

    final TabLayout tabs = findViewById(R.id.tabs);

    tabs.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            tab.view.setAlpha((float) 0.5);
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
            tab.view.setAlpha(1);
        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });

    TabLayoutMediator mediator = new TabLayoutMediator(tabs, viewPager, new TabLayoutMediator.TabConfigurationStrategy() {
        @Override
        public void onConfigureTab(@NonNull TabLayout.Tab tab, int position) {
            tab.setText("Tab" + position);
            
            /* 
            *  With this feature the TabIndicator color is ignored 
            *  or covered by the new color ex.(if alpha channel is changed the indicator can be seen through)
            */
            tab.view.setBackgroundColor(Color.parseColor(colors.get(position))); //You can use your HEX string color
        }
    });

    mediator.attach();

AutoHotKey is perfect for this kind of tasks (keyboard automation / remapping)

Just in case anybody else lands here from Google, I was bitten by this error message when using XDocument.Load(Stream) method.

XDocument xDoc = XDocument.Load(xmlStream);  

Make sure the stream position is set to 0 (zero) before you try and load the Stream, its an easy mistake I always overlook!

if (xmlStream.Position > 0)
{
    xmlStream.Position = 0;
}
XDocument xDoc = XDocument.Load(xmlStream); 

If your file is a model field within a model, you can also use ".url" in your template tag to get the image.

For example.

If this is your model:

class Foo(models.Model):
    foo = models.TextField()
    bar = models.FileField(upload_to="foo-pictures", blank = True)  

Pass the model in context in your views.

return render (request, "whatever.html", {'foo':Foo.objects.get(pk = 1)})

In your template you could have:

<img src = "{{foo.bar.url}}">

To hide static cells in UITable:

1. Add this method:

In your UITableView controller delegate class:

Objective-C:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell* cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];

    if(cell == self.cellYouWantToHide)
        return 0; //set the hidden cell's height to 0

    return [super tableView:tableView heightForRowAtIndexPath:indexPath];
}

Swift:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    var cell = super.tableView(tableView, cellForRowAtIndexPath: indexPath)

    if cell == self.cellYouWantToHide {
        return 0
    }

    return super.tableView(tableView, heightForRowAtIndexPath: indexPath)
}

This method will get called for each cell in the UITable. Once it calls it for the cell you want to hide, we set its height to 0. We identify the target cell by creating an outlet for it:

2. In the designer, create an outlet for the cell(s) you want to hide. The outlet for one such cell is called "cellYouWantToHide" above.
3. Check "Clip Subviews" in the IB for the cells you want to hide. The cells you are hiding need to have ClipToBounds = YES. Otherwise the text will pile up in the UITableView.

I'm guessing the reason you're asking is performance? There's the instr function. But that's likely to work pretty much the same behind the scenes.

Maybe you could look into full text search.

As last resorts you'd be looking at caching or precomputed columns/an indexed view.

In Chrome on the Mac, alt-tab inserts a tab character into a <textarea> field.

Here’s one: . Wee!

Both the Perl and Python solutions in this post helped me solve this problem on Mac OS X:

How to list files sorted by modification date recursively (no stat command available!)

Quoting from the post:

Perl:

find . -type f -print |
perl -l -ne '
    $_{$_} = -M;  # store file age (mtime - now)
    END {
        $,="\n";
        print sort {$_{$b} <=> $_{$a}} keys %_;  # print by decreasing age
    }'

Python:

find . -type f -print |
python -c 'import os, sys; times = {}
for f in sys.stdin.readlines(): f = f[0:-1]; times[f] = os.stat(f).st_mtime
for f in sorted(times.iterkeys(), key=lambda f:times[f]): print f'

You can use open(name, 'a')

However, when you enter filename, use inverted commas on both sides, otherwise ".txt"cannot be added to filename

Or, you could try changing the parameter type to string, then convert the string to an integer in the method. I am new to MVC, but I believe you need nullable objects in your parameter list, how else will the controller indicate that no such parameter was provided? So...

public ActionResult ViewNextItem(string id)...

Indeed, there are some beautiful inbuilt abstractions for you to accomplish your concatenation without the need to implement a custom function. Since you mentioned Spark SQL, so I am guessing you are trying to pass it as a declarative command through spark.sql(). If so, you can accomplish in a straight forward manner passing SQL command like: SELECT CONCAT(col1, '<delimiter>', col2, ...) AS concat_column_name FROM <table_name>;

Also, from Spark 2.3.0, you can use commands in lines with: SELECT col1 || col2 AS concat_column_name FROM <table_name>;

Wherein, is your preferred delimiter (can be empty space as well) and is the temporary or permanent table you are trying to read from.

It depends on how the class is constructed

Answering this question comes understanding a huge switch case statement in the C++ language standard, and one which is hard for mere mortals to get intuition about.

As a simple example of how difficult thing are:

main.cpp

#include <cassert>

int main() {
    struct C { int i; };

    // This syntax is called "default initialization"
    C a;
    // i undefined

    // This syntax is called "value initialization"
    C b{};
    assert(b.i == 0);
}

In default initialization you would start from: https://en.cppreference.com/w/cpp/language/default_initialization we go to the part "The effects of default initialization are" and start the case statement:

• "if T is a non-POD": no (the definition of POD is in itself a huge switch statement)
• "if T is an array type": no
• "otherwise, nothing is done": therefore it is left with an undefined value

Then, if someone decides to value initialize we go to https://en.cppreference.com/w/cpp/language/value_initialization "The effects of value initialization are" and start the case statement:

• "if T is a class type with no default constructor or with a user-provided or deleted default constructor": not the case. You will now spend 20 minutes Googling those terms:
  • we have an implicitly defined default constructor (in particular because no other constructor was defined)
  • it is not user-provided (implicitly defined)
  • it is not deleted (= delete)
• "if T is a class type with a default constructor that is neither user-provided nor deleted": yes
  • "the object is zero-initialized and then it is default-initialized if it has a non-trivial default constructor": no non-trivial constructor, just zero-initialize. The definition of "zero-initialize" at least is simple and does what you expect: https://en.cppreference.com/w/cpp/language/zero_initialization

This is why I strongly recommend that you just never rely on "implicit" zero initialization. Unless there are strong performance reasons, explicitly initialize everything, either on the constructor if you defined one, or using aggregate initialization. Otherwise you make things very very risky for future developers.

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

Use Tkinter there are a ton of tutorials online for this. basically, you can create events. Here is a link to a great site! This makes it easy to capture clicks. Also, if you are trying to make a game, Tkinter also has a GUI. Although, I wouldn't recommend Python for games at all, it could be a fun experiment. Good Luck!

I believe to check if a key exists in a hash you just do

if (exists $strings{$string}) {
    ...
} else {
    ...
}

The package broom comes in handy here (it uses the "tidy" format).

tidy(mg) will give a nicely formated data.frame with coefficients, t statistics etc. Works also for other models (e.g. plm, ...).

Example from broom's github repo:

lmfit <- lm(mpg ~ wt, mtcars)
require(broom)    
tidy(lmfit)

      term estimate std.error statistic   p.value
1 (Intercept)   37.285   1.8776    19.858 8.242e-19

For me its start working after putting ,: in the starting of the system variable path :--

Wherever possible, please don't use SCREEN_ORIENTATION_LANDSCAPE or SCREEN_ORIENTATION_PORTRAIT. Instead use:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

These allow the user to orient the device to either landscape orientation, or either portrait orientation, respectively. If you've ever had to play a game with a charging cable being driven into your stomach, then you know exactly why having both orientations available is important to the user.

Note: For phones, at least several that I've checked, it only allows the "right side up" portrait mode, however, SENSOR_PORTRAIT works properly on tablets.

Note: this feature was introduced in API Level 9, so if you must support 8 or lower (not likely at this point), then instead use:

setRequestedOrientation(Build.VERSION.SDK_INT < 9 ?
                        ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE :
                        ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(Build.VERSION.SDK_INT < 9 ?
                        ActivityInfo.SCREEN_ORIENTATION_PORTRAIT :
                        ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

You say that your module-info.java contains

module myModule {}

That means it declares a module called myModule, not com.pantech.myModule. Pointing this from the command format:

 -m <module-name>/<main-class>

In sibling case

<a class="uibutton confirm addClient" href="javascript:void(0);">ADD Client</a>
<input type="text" placeholder="Enter client name" style="margin: 5px;float: right" class="clientsearch large" />
<select class="mychzn-select clientList">
  <option value="">Select Client name....</option>
  <option value="1">abc</option>
</select>


 /*jQuery*/
 $(this).siblings('select').children(':selected').text()

This are special characters in html. Why dont you encode it? Check it out: http://www.degraeve.com/reference/specialcharacters.php

You could also try,

OIFS=$IFS;
IFS="\t";

animals=`cat animals.txt`
animalArray=$animals;

for animal in $animalArray
do
    echo $animal
done

IFS=$OIFS;

The ViewPager doesn't remove your fragments with the code above because it loads several views (or fragments in your case) into memory. In addition to the visible view, it also loads the view to either side of the visible one. This provides the smooth scrolling from view to view that makes the ViewPager so cool.

To achieve the effect you want, you need to do a couple of things.

1. Change the FragmentPagerAdapter to a FragmentStatePagerAdapter. The reason for this is that the FragmentPagerAdapter will keep all the views that it loads into memory forever. Where the FragmentStatePagerAdapter disposes of views that fall outside the current and traversable views.

2. Override the adapter method getItemPosition (shown below). When we call mAdapter.notifyDataSetChanged(); the ViewPager interrogates the adapter to determine what has changed in terms of positioning. We use this method to say that everything has changed so reprocess all your view positioning.

And here's the code...

private class MyPagerAdapter extends FragmentStatePagerAdapter {

    //... your existing code

    @Override
    public int getItemPosition(Object object){
        return PagerAdapter.POSITION_NONE;
    }

}

Try this to reload your current shell:

source ~/.profile

you can read /proc/meminfo to get used memory

file1 = open('/proc/meminfo', 'r') 

for line in file1: 
    if 'MemTotal' in line: 
        x = line.split()
        memTotal = int(x[1])
        
    if 'Buffers' in line: 
        x = line.split()
        buffers = int(x[1])
        
    if 'Cached' in line and 'SwapCached' not in line: 
        x = line.split()
        cached = int(x[1])
    
    if 'MemFree' in line: 
        x = line.split()
        memFree = int(x[1])

file1.close()

percentage_used = int ( ( memTotal - (buffers + cached + memFree) ) / memTotal * 100 )
print(percentage_used)

In case you use yarn:

yarn config set strict-ssl false

Simple Solution will be to match local master branch HEAD to origin/master branch HEAD

git reset --hard origin/master

PS: origin/master - is remote pointer to master branch. You can replace master with any branch name

simple is the best and works in every version.

if a>10: 
    value="b"
else: 
    value="c"

You can build the Dockerfile from the parent directory:

docker build -t <some tag> -f <dir/dir/Dockerfile> .

UPDATE - I do not have Total DNS enabled at GoDaddy because the domain is hosted at DiscountASP. As such, I could not add an A Record and that is why GoDaddy was only offering to forward my subdomain to a different site. I finally realized that I had to go to DiscountASP to add the A Record to point to DreamHost. Now waiting to see if it all works!

Of course, use the stinkin' IP! I'm not sure why that wasn't registering for me. I guess their helper text example of pointing to another url was throwing me off.

Thanks for both of the replies. I 'got it' as soon as I read Bryant's response which was first but Saif kicked it up a notch and added a little more detail.

Thanks!

This is how I write my AsyncTask

This is similar to hansen_j's solution except that it uses url namespaces, admin: being the admin's default application namespace.

Just to make things even worse, in some situations, no-cache can't be used, but no-store can:

http://faindu.wordpress.com/2008/04/18/ie7-ssl-xml-flex-error-2032-stream-error/

SELECT *
FROM ecs_table
WHERE (start_date, end_date) OVERLAPS ('2012-01-01'::DATE, '2012-04-12'::DATE + interval '1');

YES you can!! The solution should be easy, safe, and performant...

I'm new to postgresql, but it seems you can create computed columns by using an expression index, paired with a view (the view is optional, but makes makes life a bit easier).

Suppose my computation is md5(some_string_field), then I create the index as:

CREATE INDEX some_string_field_md5_index ON some_table(MD5(some_string_field));

Now, any queries that act on MD5(some_string_field) will use the index rather than computing it from scratch. For example:

SELECT MAX(some_field) FROM some_table GROUP BY MD5(some_string_field);

You can check this with explain.

However at this point you are relying on users of the table knowing exactly how to construct the column. To make life easier, you can create a VIEW onto an augmented version of the original table, adding in the computed value as a new column:

CREATE VIEW some_table_augmented AS 
   SELECT *, MD5(some_string_field) as some_string_field_md5 from some_table;

Now any queries using some_table_augmented will be able to use some_string_field_md5 without worrying about how it works..they just get good performance. The view doesn't copy any data from the original table, so it is good memory-wise as well as performance-wise. Note however that you can't update/insert into a view, only into the source table, but if you really want, I believe you can redirect inserts and updates to the source table using rules (I could be wrong on that last point as I've never tried it myself).

Edit: it seems if the query involves competing indices, the planner engine may sometimes not use the expression-index at all. The choice seems to be data dependant.

A Function will not work, nor is it necessary:

Sub OpenWorkbook()
    Dim r1 As Range, r2 As Range, o As Workbook
    Set r1 = ThisWorkbook.Sheets("Sheet1").Range("A1")
    Set o = Workbooks.Open(Filename:="C:\TestFolder\ABC.xlsx")
    Set r2 = ActiveWorkbook.Sheets("Sheet1").Range("B2")
    [r1] = [r2]
    o.Close
End Sub

You can sandwich statements between objc_sync_enter(obj: AnyObject?) and objc_sync_exit(obj: AnyObject?). The @synchronized keyword is using those methods under the covers. i.e.

objc_sync_enter(self)
... synchronized code ...
objc_sync_exit(self)

The Solution to this problem, tends to differ slightly from case to case. The general way to solve it is to
1.) right-click the bootstrap pill and select inspect or inspect element if firefox
2.) copy the css selector for the rule that changes the color
3.) modify it in your custom css file like so...

.TheCssSelectorYouJustCopied{
    background-color: #ff0000!important;//or any other color
}

I'd start with something like this (and if there is something wrong with my code, I'd of course appreciate any comment):

public class ItemsList extends ListActivity {

private ItemsAdapter adapter;

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

    setContentView(R.layout.items_list);

    this.adapter = new ItemsAdapter(this, R.layout.items_list_item, ItemManager.getLoadedItems());
    setListAdapter(this.adapter);
}

private class ItemsAdapter extends ArrayAdapter<Item> {

    private Item[] items;

    public ItemsAdapter(Context context, int textViewResourceId, Item[] items) {
        super(context, textViewResourceId, items);
        this.items = items;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        if (v == null) {
            LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.items_list_item, null);
        }

        Item it = items[position];
        if (it != null) {
            ImageView iv = (ImageView) v.findViewById(R.id.list_item_image);
            if (iv != null) {
                iv.setImageDrawable(it.getImage());
            }
        }

        return v;
    }
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    this.adapter.getItem(position).click(this.getApplicationContext());
}
}

E.g. extending ArrayAdapter with own type of Items (holding information about your pictures) and overriden getView() method, that prepares view for items within list. There is also method add() on ArrayAdapter to add items to the end of the list.

R.layout.items_list is simple layout with ListView

R.layout.items_list_item is layout representing one item in list

^(\(?[0-9]{3}\)?)((\s|\-){1})?[0-9]{3}((\s|\-){1})?[0-9]{4}$

Assuming you are validating US phone numbers, this will do the trick.

First, we allow 0 or 1 open parentheses to start \(?

Then, we allow 3 consecutive digits between 0-9 [0-9]{3}

After, we repeat the first step and allow 0 or 1 closing parentheses \)?

For the second grouping, we start by allowing a space or a hyphen 0 or 1 times ((\s|\-){1})?

This is repeated between the second and third grouping of numbers, and we check for 3 consecutive digits then four consecutive digits to end it. For US phone numbers I think this covers the bases for a lot of different ways that people might format the number, but is restrictive enough that they can't pass an unreasonable string.

This works on SQL Server 2005 (edited to reflect your clarification):

select *
from Things t
where t.ThingID in (
    select top 10 ThingID
    from Things tt
    where tt.Section = t.Section and tt.ThingDate = @Date
    order by tt.DateEntered desc
    )
    and t.ThingDate = @Date
order by Section, DateEntered desc

I would use something along these lines...

 netstat -rn | grep "default" | awk '{print $2}'

Elements with the disabled attribute are not submitted or you can say their values are not posted (see the second bullet point under Step 3 in the HTML 5 spec for building the form data set).

I.e.,

<input type="textbox" name="Percentage" value="100" disabled="disabled" /> 

FYI, per 17.12.1 in the HTML 4 spec:

1. Disabled controls do not receive focus.
2. Disabled controls are skipped in tabbing navigation.
3. Disabled controls cannot be successfully posted.

You can use readonly attribute in your case, by doing this you will be able to post your field's data.

I.e.,

<input type="textbox" name="Percentage" value="100" readonly="readonly" />

FYI, per 17.12.2 in the HTML 4 spec:

1. Read-only elements receive focus but cannot be modified by the user.
2. Read-only elements are included in tabbing navigation.
3. Read-only elements are successfully posted.

You can use negated character classes to exclude certain characters: for example [^abcde] will match anything but a,b,c,d,e characters.

Instead of specifying all the characters literally, you can use shorthands inside character classes: [\w] (lowercase) will match any "word character" (letter, numbers and underscore), [\W] (uppercase) will match anything but word characters; similarly, [\d] will match the 0-9 digits while [\D] matches anything but the 0-9 digits, and so on.

If you use PHP you can take a look at the regex character classes documentation.

I just finished writing my own optimised implementation of normalized cross-correlation for N-dimensional arrays. You can get it from here.

It will calculate cross-correlation either directly, using scipy.ndimage.correlate, or in the frequency domain, using scipy.fftpack.fftn/ifftn depending on whichever will be quickest.

There are two ways:

1. Call the non-static method from an instance within the static method. See fabien's answer for an oneliner sample... although I would strongly recommend against it. With his example he creates an instance of the class and only uses it for one method, only to have it dispose of it later. I don't recommend it because it treats an instance like a static function.
2. Change the static method to a non-static.

General differences

There are several classes which implement the CharSequence interface besides String. Among these are

• StringBuilder for variable-length character sequences which can be modified
• CharBuffer for fixed-length low-level character sequences which can be modified

Any method which accepts a CharSequence can operate on all of these equally well. Any method which only accepts a String will require conversion. So using CharSequence as an argument type in all the places where you don't care about the internals is prudent. However you should use String as a return type if you actually return a String, because that avoids possible conversions of returned values if the calling method actually does require a String.

Also note that maps should use String as key type, not CharSequence, as map keys must not change. In other words, sometimes the immutable nature of String is essential.

Specific code snippet

As for the code you pasted: simply compile that, and have a look at the JVM bytecode using javap -v. There you will notice that both obj and str are references to the same constant object. As a String is immutable, this kind of sharing is all right.

The + operator of String is compiled as invocations of various StringBuilder.append calls. So it is equivalent to

System.out.println(
  (new StringBuilder())
  .append("output is : ")
  .append((Object)obj)
  .append(" ")
  .append(str)
  .toString()
)

I must confess I'm a bit surprised that my compiler javac 1.6.0_33 compiles the + obj using StringBuilder.append(Object) instead of StringBuilder.append(CharSequence). The former probably involves a call to the toString() method of the object, whereas the latter should be possible in a more efficient way. On the other hand, String.toString() simply returns the String itself, so there is little penalty there. So StringBuilder.append(String) might be more efficient by about one method invocation.

You should join T1 and T2 tables using sql joins in order to analyze from two tables. Link for learn joins : https://www.w3schools.com/sql/sql_join.asp

It's easier and cleaner to do it with CSS.

HTML:

<div ng-repeat="file in files" class="file">
  {{ file.name }}
</div>

CSS:

.file:last-of-type {
    color: #800;
}

The :last-of-type selector is currently supported by 98% of browsers

This fixed me

var width = window.innerWidth;
var height = window.innerHeight;

You can use the below simple method of sorting:

datatable.DefaultView.Sort = "Col2 ASC,Col3 ASC,Col4 ASC";

By the above method, you will be able to sort N number of columns.

adding a br tag between the divs worked. add br tag between two divs that are display:table-row in a parent with display:table

sysv-rc-conf is an alternate option for Ubuntu.

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

Dijkstra's Algorithm assumes that all edges are positive weighted and this assumption helps the algorithm run faster ( O(V^2) ) than others which take into account the possibility of negative edges (e.g bellman ford's algorithm with complexity of O(V^3)).

This algorithm wont give the correct result in the following case where A is the source vertex:

Also, Dijkstra's Algorithm may sometimes give correct solution even if there are negative edges. Following is an example of such a case:

It will never detect a negative cycle and always produce a result which will always be incorrect if a negative weight cycle is reachable from the source, as in such a case there exists no shortest path in the graph from the source vertex.

_{Note: This is not a duplicate, because the OP is aware that the image from cv2.imread is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)}

To illustrate, I've opened up this same color JPEG image:

once using the conversion

img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

and another by loading it in gray scale mode

img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom

I've summed up the diff too to see

import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image

I tried all cv2.imread() modes

Among all the IMREAD_ modes for cv2.imread(), only IMREAD_COLOR and IMREAD_ANYCOLOR can be converted using COLOR_BGR2GRAY, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE

The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)

Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.

In brief, let's not mix the versions and types in the processing pipeline.

So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Using current browsers you can use it like this:

img {
  -webkit-filter: grayscale(100%); /* Chrome, Safari, Opera */
  filter: grayscale(100%);
}

and to remedy it:

img:hover{
   -webkit-filter: grayscale(0%); /* Chrome, Safari, Opera */
   filter: grayscale(0%);
}

worked with me and is much shorter. There is even more one can do within the CSS:

filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() |
        hue-rotate() | invert() | opacity() | saturate() | sepia() | url();

For more information and supporting browsers see this: http://www.w3schools.com/cssref/css3_pr_filter.asp

In ONLINE mode the new index is built while the old index is accessible to reads and writes. any update on the old index will also get applied to the new index. An antimatter column is used to track possible conflicts between the updates and the rebuild (ie. delete of a row which was not yet copied). See Online Index Operations. When the process is completed the table is locked for a brief period and the new index replaces the old index. If the index contains LOB columns, ONLINE operations are not supported in SQL Server 2005/2008/R2.

In OFFLINE mode the table is locked upfront for any read or write, and then the new index gets built from the old index, while holding a lock on the table. No read or write operation is permitted on the table while the index is being rebuilt. Only when the operation is done is the lock on the table released and reads and writes are allowed again.

Note that in SQL Server 2012 the restriction on LOBs was lifted, see Online Index Operations for indexes containing LOB columns.

I get this error when my project .net framework version does not match the framework version of the DLL I am linking to. In my case, I was getting:

"The type or namespace name 'UserVoice' could not be found (are you missing a using directive or an assembly reference?).

UserVoice was .Net 4.0, and my project properties were set to ".Net 4.0 Client Profile". Changing to .Net 4.0 on the project cleared the error. I hope this helps someone.

this refactored code will do it

let toTimestamp = strDate => Date.parse(strDate)

this works on all modern browsers except ie8-

I also faced the same issue. The solution which helped me was I downloaded and installed 64 bit JDK from this link and set the "java_home" variable to the new JDK installed path like C:\Program Files\Java\jdk1.7.0_45. Hope this helps.

This line

For me actually the problem is the File object's class path is from <project folder path> or ./src, so use File file = new File("./src/xxx.txt"); solved my problem

Meteor is a framework built ontop of node.js. It uses node.js to deploy but has several differences.

The key being it uses its own packaging system instead of node's module based system. It makes it easy to make web applications using Node. Node can be used for a variety of things and on its own is terrible at serving up dynamic web content. Meteor's libraries make all of this easy.

This works smoothly. Try this.

Following is the JS coding.

 <script>

        $(document).ready(function () {
            $('#completionDate').datepicker({
                dateFormat: 'yy-mm-dd', // enter date format you prefer (e.g. 2018-10-09)
                changeMonth: true,
                changeYear: true,
                yearRange: "-50:+10",
                clickInput: true,

                onSelect: function (date) {
                    loadMusterChit();
                }

            });
        });

    </script>

There is always this of course:

(async () => {
    await ...

    // all of the script.... 

})();
// nothing else

This makes a quick function with async where you can use await. It saves you the need to make an async function which is great! //credits Silve2611

This worked for me:

Step 1 : echo ps aux | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{ print $2 }'

This above command return "process_id"

Step 2: kill -9 process_id
// This process_id same as Step 1: output

A property that has only a getter is said to be readonly. Cause no setter is provided, to change the value of the property (from outside).

C# has has a keyword readonly, that can be used on fields (not properties). A field that is marked as "readonly", can only be set once during the construction of an object (in the constructor).

private string _name = "Foo"; // field for property Name;
private bool _enabled = false; // field for property Enabled;

public string Name{ // This is a readonly property.
  get {
    return _name;  
  }
}

public bool Enabled{ // This is a read- and writeable property.
  get{
    return _enabled;
  }
  set{
    _enabled = value;
  }
} 

Further to meteore's answer, I found the code

df.index = df.index.astype('i8')

doesn't work for me. So I put my code here for the convenience of others stuck with this issue.

city_cluster_df = pd.read_csv(text_filepath, encoding='utf-8')
# the field 'city_en' is a string, when converted to Numpy array, it will be an object
city_cluster_arr = city_cluster_df[['city_en','lat','lon','cluster','cluster_filtered']].to_records()
descr=city_cluster_arr.dtype.descr
# change the field 'city_en' to string type (the index for 'city_en' here is 1 because before the field is the row index of dataframe)
descr[1]=(descr[1][0], "S20")
newArr=city_cluster_arr.astype(np.dtype(descr))

Be careful using SelectedItem.Text... If there is no item selected, then SelectedItem will be null and SelectedItem.Text will generate a null-value exception.

.NET should have provided a SelectedText property like the SelectedValue property that returns String.Empty when there is no selected item.

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

There is no b['body'] in python. You have to use get_payload.

if isinstance(mailEntity.get_payload(), list):
    for eachPayload in mailEntity.get_payload():
        ...do things you want...
        ...real mail body is in eachPayload.get_payload()...
else:
    ...means there is only text/plain part....
    ...use mailEntity.get_payload() to get the body...

Good Luck.

Replacing server=localhost with server=.\SQLEXPRESS might do the job.

There's many different ways to go about this, but I'm partial to describeBy in the psych package:

describeBy(df$dt, df$group, mat = TRUE) 

You can save object in preferences without using any library, first of all your object class must implement Serializable:

public class callModel implements Serializable {

private long pointTime;
private boolean callisConnected;

public callModel(boolean callisConnected,  long pointTime) {
    this.callisConnected = callisConnected;
    this.pointTime = pointTime;
}
public boolean isCallisConnected() {
    return callisConnected;
}
public long getPointTime() {
    return pointTime;
}

}

Then you can easily use these two method to convert object to string and string to object:

 public static <T extends Serializable> T stringToObjectS(String string) {
    byte[] bytes = Base64.decode(string, 0);
    T object = null;
    try {
        ObjectInputStream objectInputStream = new ObjectInputStream(new ByteArrayInputStream(bytes));
        object = (T) objectInputStream.readObject();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return object;
}

 public static String objectToString(Parcelable object) {
    String encoded = null;
    try {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
        objectOutputStream.writeObject(object);
        objectOutputStream.close();
        encoded = new String(Base64.encodeToString(byteArrayOutputStream.toByteArray(), 0));
    } catch (IOException e) {
        e.printStackTrace();
    }
    return encoded;
}

To save:

SharedPreferences  mPrefs = getPreferences(MODE_PRIVATE);
Editor prefsEditor = mPrefs.edit();
prefsEditor.putString("MyObject", objectToString(callModelObject));
prefsEditor.commit();

To read

String value= mPrefs.getString("MyObject", "");
MyObject obj = stringToObjectS(value);

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

This is most likely not an answer to the issue itself but this question pops up as first result when searching for Sql declare scalar variable hence i share a possible solution to this error.

In my case this error was caused by the use of ; after a SQL statement. Just remove it and the error will be gone.

I guess the cause is the same as @IronSean already posted in an comment above:

it's worth noting that using GO (or in this case ;) causes a new branch where declared variables aren't visible past the statement.

For example:

DECLARE @id int
SET @id = 78

SELECT * FROM MyTable WHERE Id = @var; <-- remove this character to avoid the error message
SELECT * FROM AnotherTable WHERE MyTableId = @var

Note: the commit 5e1361c from brian m. carlson (bk2204) (for git 1.9/2.0 Q1 2014) deals with a special case in term of log decoration with tags:

log: properly handle decorations with chained tags

git log did not correctly handle decorations when a tag object referenced another tag object that was no longer a ref, such as when the second tag was deleted.
The commit would not be decorated correctly because parse_object had not been called on the second tag and therefore its tagged field had not been filled in, resulting in none of the tags being associated with the relevant commit.

Call parse_object to fill in this field if it is absent so that the chain of tags can be dereferenced and the commit can be properly decorated.
Include tests as well to prevent future regressions.

Example:

git tag -a tag1 -m tag1 &&
git tag -a tag2 -m tag2 tag1 &&
git tag -d tag1 &&
git commit --amend -m shorter &&
git log --no-walk --tags --pretty="%H %d" --decorate=full

If you're developing an application that transfers data using AMF (fairly common in a particular set of GIS web APIs I use regularly), Fiddler does not currently provide an AMF decoder that will allow you to easily view the binary data in an easily-readable format. Charles provides this functionality.

You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.

This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.

This also works if you are looping over an object.

unset($object->$key);

No need to use brackets.

Another useful variant is pipe to tr:

echo "${my_array[@]}" | tr ' ' '\n'

This looks simple and compact

I was having the same problem, but using Long type. I changed for INT and it worked for me.

CREATE TABLE lists (
 id INT NOT NULL AUTO_INCREMENT,
 desc varchar(30),
 owner varchar(20),
 visibility boolean,
 PRIMARY KEY (id)
 );

I'd like to add a little CoffeeScript code (not field tested):

$ ->
    $(window).bind 'keypress', (event) ->
        if event.keyCode == 13
            unless {'TEXTAREA', 'SELECT'}[event.originalEvent.srcElement.tagName]
                event.preventDefault()

(I hope you like the nice trick in the unless clause.)

NW.js

(Previously known as node-webkit)

I would suggest NW.js if you are familiar with Node or experienced with JavaScript.

NW.js is an app runtime based on Chromium and node.js.

Features

• Apps written in modern HTML5, CSS3, JS and WebGL
• Complete support for Node.js APIs and all its third party modules.
• Good performance: Node and WebKit run in the same thread: Function calls are made straightforward; objects are in the same heap and can just reference each other
• Easy to package and distribute apps
• Available on Linux, Mac OS X and Windows

You can find the NW.js repo here, and a good introduction to NW.js here. If you fancy learning Node.js I would recommend this SO post with a lot of good links.

# file? will only return true for files
File.file?(filename)

and

# Will also return true for directories - watch out!
File.exist?(filename)

In ES2015, using the shorthand property declaration syntax for object literals, you can log objects while also concisely preserving your variable names:

console.log("bwib:", bwib, "bwab:", bwab, "bwob": bwob) // old way A
console.log({bwib: bwib, bwab: bwab, bwob: bwob})       // old way B

console.log({bwib, bwab, bwob})                         // ES2015+ way

I make this in iOS 9 and Swift 2.0 if I use UINavigationController

self.navigationController?.navigationBar.barStyle = UIBarStyle.Black

And I make this if I use modal segue

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .LightContent
}

I use sweetalert2 library. It's really simple, a lot of customization, modern, animated windows, eye-catching, and also nice design.

Swal.fire({
  icon: 'error',
  title: 'Oops...',
  text: 'Something went wrong!',
  footer: '<a href>Why do I have this issue?</a>'
})

Check this link

You can try this:

CommandArgument='<%# "scrapid=" + Eval("ScrapId")+"&"+"UserId="+ Eval("UserId")%>'

The answer to this question is, perhaps surprisingly, never, or more realistically, only when you are forced to for interoperability with legacy code. This is the recommendation in Effective Java, 3rd Edition by Joshua Bloch:

There is no reason to use Java serialization in any new system you write

Oracle's chief architect, Mark Reinhold, is on record as saying removing the current Java serialization mechanism is a long-term goal.

Why Java serialization is flawed

Java provides as part of the language a serialization scheme you can opt in to, by using the Serializable interface. This scheme however has several intractable flaws and should be treated as a failed experiment by the Java language designers.

• It fundamentally pretends that one can talk about the serialized form of an object. But there are infinitely many serialization schemes, resulting in infinitely many serialized forms. By imposing one scheme, without any way of changing the scheme, applications can not use a scheme most appropriate for them.
• It is implemented as an additional means of constructing objects, which bypasses any precondition checks your constructors or factory methods perform. Unless tricky, error prone, and difficult to test extra deserialization code is written, your code probably has a gaping security weakness.
• Testing interoperability of different versions of the serialized form is very difficult.
• Handling of immutable objects is troublesome.

What to do instead

Instead, use a serialization scheme that you can explicitly control. Such as Protocol Buffers, JSON, XML, or your own custom scheme.

My Attempt ( JsFiddle)

Javascript

$(document).ready(function () {
    $('#buttons input[type=button]').on('click', function () {
        var qty = $(this).data('quantity');
        var price = $('#totalPrice').text(); 
        $('#count').val(price * qty);
    });
});

Html

  Product price:$500
<br>Total price: $<span id='totalPrice'>500</span>
<br>
<div id='buttons'>
    <input id='qty2' type="button" data-quantity='2' value="2&#x00A;Qty">
    <input id='qty2' type="button" class="mnozstvi_sleva" data-quantity='4' value="4&#x00A;Qty">
</div>
<br>Total
<input type="text" id="count" value="1">

I have created some simple function you can use to convert time to any timezone :

function convertTimeToLocal($datetime,$timezone='Europe/Dublin') {
        $given = new DateTime($datetime, new DateTimeZone("UTC"));
        $given->setTimezone(new DateTimeZone($timezone));
        $output = $given->format("Y-m-d"); //can change as per your requirement
        return $output;
}

This is a possible solution for you:

a = [15, 12, 10]
b = sorted(a)
print b # --> b = [10, 12, 15]
c = 13
for i in range(len(b)):
    if b[i] > c:
        break
d = b[:i] + [c] + b[i:]
print d # --> d = [10, 12, 13, 15]

Using the "Replace all" functionality, you can delete a line directly by ending your pattern with:

• If your file have linux (LF) line ending : $\n?
• If your file have windows (CRLF) line ending : $(\r\n)?

For instance, in your case :

.*#RedirectMatch Permanent.*$\n?

You are trying to group code according to struct. C grouping is by file. You put all the functions and internal variables in a header or a header and a object ".o" file compiled from a c source file.

It is not necessary to reinvent object-orientation from scratch for a C program, which is not an object oriented language.

I have seen this before. It is a strange thing. Coders, some of them, have an aversion to passing an object they want to change into a function to change it, even though that is the standard way to do so.

I blame C++, because it hid the fact that the class object is always the first parameter in a member function, but it is hidden. So it looks like it is not passing the object into the function, even though it is.

Client.addClient(Client& c); // addClient first parameter is actually 
                             // "this", a pointer to the Client object.

C is flexible and can take passing things by reference.

A C function often returns only a status byte or int and that is often ignored. In your case a proper form might be

 err = addClient( container_t  cnt, client_t c);
 if ( err != 0 )
   { fprintf(stderr, "could not add client (%d) \n", err ); 

addClient would be in Client.h or Client.c

The Github API does not provide the needed information anymore. Take a look at the releases page, mentioned in Stan Towianski's answer. As we discussed in the comments to that answer, the Github API only reports the downloads of 1 of the three files he offers per release.

I have checked the solutions, provided in some other answers to this questions. Vonc's answer presents the essential part of Michele Milidoni's solution. I installed his gdc script with the following result

# ./gdc stant
mdcsvimporter.mxt: 37 downloads
mdcsvimporter.mxt: 80 downloads
How-to-use-mdcsvimporter-beta-16.zip: 12 downloads

As you can clearly see, gdc does not report the download count of the tar.gz and zip files.

If you want to check without installing anything, try the web page where Somsubhra has installed the solution, mentioned in his answer. Fill in 'stant' as Github username and 'mdcsvimporter2015' as Repository name and you will see things like:

Download Info:
mdcsvimporter.mxt(0.20MB) - Downloaded 37 times.
Last updated on 2015-03-26

Alas, once again only a report without the downloads of the tar.gz and zip files. I have carefully examined the information that Github's API returns, but it is not provided anywhere. The download_count that the API does return is far from complete nowadays.

Try mapping the sharepoint library to a drive letter in windows. Then select the drive and path in your code.

If you want to modify this I'd go with either of the following:

List<string[]> results;

-- or --

List<List<string>> results;

depending on your needs...

As correct as the other answers may be, in the context that the quote was in, hashing is a tool that may be used in securing information, encryption is a process that takes information and makes it very difficult for unauthorized people to read/use.

There are three methods you can pass values in the function

1. Pass by value

   void f(int n){
       n = n + 10;
   }
   
   int main(){
       int x = 3;
       f(x);
       cout << x << endl;
   }
   

   Output: 3. Disadvantage: When parameter x pass through f function then compiler creates a copy in memory in of x. So wastage of memory.

2. Pass by reference

   void f(int& n){
       n = n + 10;
   }
   
   int main(){
       int x = 3;
       f(x);
       cout << x << endl;
   }
   

   Output: 13. It eliminate pass by value disadvantage, but if programmer do not want to change the value then use constant reference

3. Constant reference

   void f(const int& n){
       n = n + 10; // Error: assignment of read-only reference  ‘n’
   }
   
   int main(){
       int x = 3;
       f(x);
       cout << x << endl;
   }
   

   Output: Throw error at n = n + 10 because when we pass const reference parameter argument then it is read-only parameter, you cannot change value of n.

You need to seek to the end of the file and then ask for the position:

fseek(fp, 0L, SEEK_END);
sz = ftell(fp);

You can then seek back, e.g.:

fseek(fp, 0L, SEEK_SET);

or (if seeking to go to the beginning)

rewind(fp);

Execute the workbench.action.reloadWindow command.

There are some ways to do so:

1. Open the command palette (Ctrl + Shift + P) and execute the command:

   >Reload Window    
   

2. Define a keybinding for the command (for example CTRL+F5) in keybindings.json:

   [
     {
       "key": "ctrl+f5",
       "command": "workbench.action.reloadWindow",
       "when": "editorTextFocus"
     }
   ]
   

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

UPDATED 2020 August: MacOs Cataline

Install homebrew

https://docs.brew.sh/Installation

mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

Add the path:

sudo nano  ~/.bash_profile

Add this line:
export PATH="$HOME/homebrew/bin:$PATH"

Install python3:

brew install python

This python (v3) install pip3, in order to use only 'pip' , add an alias:

sudo nano  ~/.bash_profile
Add this line:
alias pip=pip3

UPDATED 2019 October: MacOs Mojave

MacOS comes with python2, but not with pip. Anyway, it's better to manage it with homebrew, you must install it before:

https://docs.brew.sh/Installation

Install python2:

brew install python

WARNING: for a modern macOS (2019) this can install python3, and for python2 you really need to do: brew install python@2

Install python3:

brew install python3

UPDATE: Python 3

If you install python3, pip will be installed automatically.

brew install python3

NEW 2019: now to use pip version 3, use pip3 , or you can execute: python3, to use version 3. When you install packages with pip3 they will be separated from python2.

OLD: You need only to upgrade pip, but before that you need create a virtual environment to work with Python 3. You can use a project folder or any folder:

python3 -m venv venv
source venv/bin/activate
pip install --upgrade pip

Check the versions:

pip -V
python --version

NEW 2019:
pip3 -V
python3 --version

To deactivate the environment:

$ deactivate

Being a programmer made this 10-minute Winform project. It's been useful for me. Making this app to a context menu for file explorer would save more clicks.

Use COALESCE() instead:

SELECT COALESCE(Field,'Empty') from Table;

It functions much like ISNULL, although provides more functionality. Coalesce will return the first non null value in the list. Thus:

SELECT COALESCE(null, null, 5); 

returns 5, while

SELECT COALESCE(null, 2, 5);

returns 2

Coalesce will take a large number of arguments. There is no documented maximum. I tested it will 100 arguments and it succeeded. This should be plenty for the vast majority of situations.

Brew already provide a command to uninstall itself (this will remove everything you installed with Homebrew):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

If you failed to run this command due to permission (like run as second user), run again with sudo

Then you can install again:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

The -std=c++14 flag is not supported on GCC 4.8. If you want to use C++14 features you need to compile with -std=c++1y. Using godbolt.org it appears that the earilest version to support -std=c++14 is GCC 4.9.0 or Clang 3.5.0

The m2e plugin uses it's own distribution of Maven, packaged with the plugin.

In order to use Maven from command line, you need to have it installed as a standalone application. Here is an instruction explaining how to do it in Windows

Once Maven is properly installed (i.e. be sure that MAVEN_HOME, JAVA_HOME and PATH variables are set correctly): you must run mvn eclipse:eclipse from the directory containing the pom.xml.

You can't set a favicon from CSS - if you want to do this explicitly you have to do it in the markup as you described.

Most browsers will, however, look for a favicon.ico file on the root of the web site - so if you access http://example.com most browsers will look for http://example.com/favicon.ico automatically.

In your UITableViewCell's XIB in Attribute Inspector set value of Selection to None.

These days something like the following will suffice:

HttpHeaders headers = new HttpHeaders();
headers.setBearerAuth(accessToken);
restTemplate.exchange(RequestEntity.get(new URI(url)).headers(headers).build(), returnType);

You must analyse the actual HTML output, for the hint.

By giving the path like this means "from current location", on the other hand if you start with a / that would mean "from the context".

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

Actually I do this myself. I have a table called 'Comments' which contains comments for records in 3 other tables. Neither solution actually handles everything you probably want it to. In your case, you would do this:

Solution 1:

1. Add a tinyint field to employees_ce and employees_sn that has a default value which is different in each table (This field represents a 'table identifier', so we'll call them tid_ce & tid_sn)

2. Create a Unique Index on each table using the table's PK and the table id field.

3. Add a tinyint field to your 'Deductions' table to store the second half of the foreign key (the Table ID)

4. Create 2 foreign keys in your 'Deductions' table (You can't enforce referential integrity, because either one key will be valid or the other...but never both:

   ALTER TABLE [dbo].[Deductions]  WITH NOCHECK ADD  CONSTRAINT [FK_Deductions_employees_ce] FOREIGN KEY([id], [fk_tid])
   REFERENCES [dbo].[employees_ce] ([empid], [tid])
   NOT FOR REPLICATION 
   GO
   ALTER TABLE [dbo].[Deductions] NOCHECK CONSTRAINT [FK_600_WorkComments_employees_ce]
   GO
   ALTER TABLE [dbo].[Deductions]  WITH NOCHECK ADD  CONSTRAINT [FK_Deductions_employees_sn] FOREIGN KEY([id], [fk_tid])
   REFERENCES [dbo].[employees_sn] ([empid], [tid])
   NOT FOR REPLICATION 
   GO
   ALTER TABLE [dbo].[Deductions] NOCHECK CONSTRAINT [FK_600_WorkComments_employees_sn]
   GO
   
   employees_ce
   --------------
   empid    name     tid
   khce1   prince    1
   
   employees_sn
   ----------------
   empid    name     tid 
   khsn1   princess  2
   
   deductions
   ----------------------
   id      tid       name  
   khce1   1         gold
   khsn1   2         silver         
   ** id + tid creates a unique index **
   

Solution 2: This solution allows referential integrity to be maintained: 1. Create a second foreign key field in 'Deductions' table , allow Null values in both foreign keys, and create normal foreign keys:

    employees_ce
    --------------
    empid   name
    khce1   prince 

    employees_sn
    ----------------
    empid   name     
    khsn1   princess 

    deductions
    ----------------------
    idce    idsn      name  
    khce1   *NULL*    gold
    *NULL*  khsn1     silver         

Integrity is only checked if the column is not null, so you can maintain referential integrity.

Investigating the Cause of SQL Server High CPU

For me this helped a lot:

SELECT s.session_id,
    r.status,
    r.blocking_session_id 'Blk by',
    r.wait_type,
    wait_resource,
    r.wait_time / (1000 * 60) 'Wait M',
    r.cpu_time,
    r.logical_reads,
    r.reads,
    r.writes,
    r.total_elapsed_time / (1000 * 60) 'Elaps M',
    Substring(st.TEXT,(r.statement_start_offset / 2) + 1,
    ((CASE r.statement_end_offset
WHEN -1
THEN Datalength(st.TEXT)
ELSE r.statement_end_offset
END - r.statement_start_offset) / 2) + 1) AS statement_text,
    Coalesce(Quotename(Db_name(st.dbid)) + N'.' + Quotename(Object_schema_name(st.objectid, st.dbid)) + N'.' +
    Quotename(Object_name(st.objectid, st.dbid)), '') AS command_text,
    r.command,
    s.login_name,
    s.host_name,
    s.program_name,
    s.last_request_end_time,
    s.login_time,
    r.open_transaction_count
FROM sys.dm_exec_sessions AS s
    JOIN sys.dm_exec_requests AS r
ON r.session_id = s.session_id
    CROSS APPLY sys.Dm_exec_sql_text(r.sql_handle) AS st
WHERE r.session_id != @@SPID
ORDER BY r.cpu_time desc

In the fields of status, wait_type and cpu_time you can find the most cpu consuming task that is running right now.

For me the resource folder was getting excluded on a maven update/build. I went to Build Path>Source and found that src/main/resources have "Excluded **". I removed that entry (Clicked on Excluded **>Remove>Apply and Close).

Then it worked fine.

You say your website is in http://localhost/mywebsite, and let's say that your image is inside a subfolder named pictures/:

Absolute path

If you use an absolute path, / would point to the root of the site, not the root of the document: localhost in your case. That's why you need to specify your document's folder in order to access the pictures folder:

"/mywebsite/pictures/picture.png"

And it would be the same as:

"http://localhost/mywebsite/pictures/picture.png"

Relative path

A relative path is always relative to the root of the document, so if your html is at the same level of the directory, you'd need to start the path directly with your picture's directory name:

"pictures/picture.png"

But there are other perks with relative paths:

dot-slash (./)

Dot (.) points to the same directory and the slash (/) gives access to it:

So this:

"pictures/picture.png"

Would be the same as this:

"./pictures/picture.png"

Double-dot-slash (../)

In this case, a double dot (..) points to the upper directory and likewise, the slash (/) gives you access to it. So if you wanted to access a picture that is on a directory one level above of the current directory your document is, your URL would look like this:

"../picture.png"

You can play around with them as much as you want, a little example would be this:

Let's say you're on directory A, and you want to access directory X.

- root
   |- a
      |- A
   |- b
   |- x
      |- X

Your URL would look either:

Absolute path

"/x/X/picture.png"

Or:

Relative path

"./../x/X/picture.png"

See this. Its also similar problem. Working i tried.

Since the OP mentioned in a comment that he's using Microsoft.Xna.Framework.Graphics.Color rather than System.Drawing.Color you can first create a System.Drawing.Color then convert it to a Microsoft.Xna.Framework.Graphics.Color

public static Color FromName(string colorName)
{
    System.Drawing.Color systemColor = System.Drawing.Color.FromName(colorName);   
    return new Color(systemColor.R, systemColor.G, systemColor.B, systemColor.A); //Here Color is Microsoft.Xna.Framework.Graphics.Color
}

I know you said that you couldn't install any software, but I'm not sure how tight that restriction is. Anyway, I had the same issue (trying to concatenate two files with presumably the same headers) and I thought I'd provide an alternative answer for others who arrive at this page, since it worked just great for me.

After trying a whole bunch of commands in windows and being severely frustrated, and also trying all sorts of graphical editors that promised to be able to open large files, but then couldn't, I finally got back to my Linux roots and opened my Cygwin prompt. Two commands:

cp file1.csv out.csv
tail -n+2 file2.csv >> out.csv

For file1.csv 800MB and file2.csv 400MB, those two commands took under 5 seconds on my machine. In a Cygwin prompt, no less. I thought Linux commands were supposed to be slow in Cygwin but that approach took far less effort and was way easier than any windows approach I could find.

if you want same string output then try below else use without double quotes for proper output

$str = '20130814';
  echo date('"F Y"', strtotime($str));

//output  : "August 2013" 

Extending adam-rosenfield's solution, i think the following will work for multithreaded single producer - single consumer scenario.

int cb_push_back(circular_buffer *cb, const void *item)
{
  void *new_head = (char *)cb->head + cb->sz;
  if (new_head == cb>buffer_end) {
      new_head = cb->buffer;
  }
  if (new_head == cb->tail) {
    return 1;
  }
  memcpy(cb->head, item, cb->sz);
  cb->head = new_head;
  return 0;
}

int cb_pop_front(circular_buffer *cb, void *item)
{
  void *new_tail = cb->tail + cb->sz;
  if (cb->head == cb->tail) {
    return 1;
  }
  memcpy(item, cb->tail, cb->sz);
  if (new_tail == cb->buffer_end) {
    new_tail = cb->buffer;
  }
  cb->tail = new_tail;
  return 0;
}

If you want your user to press enter, then the raw_input() will return "", so compare the User with "":

User = raw_input('Press enter to exit...')
running = 1
while running == 1:
    Run your program
if User == "":
    break
else
    running == 1

In Year 2019, we can use Javascript's ES6 Spread syntax to do it concisely and efficiently

data = [...data, {"label": 2, "value": 13}]

Examples

var data = [_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
    ];_x000D_
    _x000D_
data = [...data, {"label" : "2", "value" : 14}] _x000D_
console.log(data)

For your case (i know it was in 2011), we can do it with map() & forEach() like below

var lab = ["1","2","3","4"];_x000D_
var val = [42,55,51,22];_x000D_
_x000D_
//Using forEach()_x000D_
var data = [];_x000D_
val.forEach((v,i) => _x000D_
   data= [...data, {"label": lab[i], "value":v}]_x000D_
)_x000D_
_x000D_
//Using map()_x000D_
var dataMap = val.map((v,i) => _x000D_
 ({"label": lab[i], "value":v})_x000D_
)_x000D_
_x000D_
console.log('data: ', data);_x000D_
console.log('dataMap : ', dataMap);

Here are some easy way to get you up and running with the XlsxWriter module.The first step is to install the XlsxWriter module.The pip installer is the preferred method for installing Python modules from PyPI, the Python Package Index:

sudo pip install xlsxwriter

Note

Windows users can omit sudo at the start of the command.

Here is a nice and simple way to do it (but on CENTOS), without braking the operating system.

yum install scl-utils

next

yum install centos-release-scl-rh

And lastly you install the version that you want, lets say python3.5

yum install rh-python35

And lastly:

scl enable rh-python35 bash

Since MAC-OS is a unix operating system, the way to do it it should be quite similar.

You can use lodash.js

_.pull(arrayName,valueToBeRemove);

In your case :- _.pull(id_tag,90);

add [] in the name of the attributes in the input tag

 <form action="" name="frm" method="post">
<input type="checkbox" name="hobby[]" value="coding">  coding &nbsp
<input type="checkbox" name="hobby[]" value="database">  database &nbsp
<input type="checkbox" name="hobby[]" value="software engineer">  soft Engineering <br>
<input type="submit" name="submit" value="submit"> 
</form>

for PHP Code :

<?php
 if(isset($_POST['submit']){
   $hobby = $_POST['hobby'];

   foreach ($hobby as $hobys=>$value) {
             echo "Hobby : ".$value."<br />";
        }
}
?>

git reset --hard origin/master

to reset it to whatever the origin was at.
