Try this condition instead:

if (string.IsNullOrWhiteSpace(MaterialTextBox.Text)) {
    // Message box
}

This will take care of some strings that only contain whitespace characters and you won't have to deal with string equality which can sometimes be tricky

Use a BindingList and set the DataPropertyName-Property of the column.

Try the following:

...
private void BindGrid()
{
    gvFilesOnServer.AutoGenerateColumns = false;

    //create the column programatically
    DataGridViewCell cell = new DataGridViewTextBoxCell();
    DataGridViewTextBoxColumn colFileName = new DataGridViewTextBoxColumn()
    {
        CellTemplate = cell, 
        Name = "Value",
        HeaderText = "File Name",
        DataPropertyName = "Value" // Tell the column which property of FileName it should use
     };

    gvFilesOnServer.Columns.Add(colFileName);

    var filelist = GetFileListOnWebServer().ToList();
    var filenamesList = new BindingList<FileName>(filelist); // <-- BindingList

    //Bind BindingList directly to the DataGrid, no need of BindingSource
    gvFilesOnServer.DataSource = filenamesList 
}

Square brackets:

jsObj['key' + i] = 'example' + 1;

In JavaScript, all arrays are objects, but not all objects are arrays. The primary difference (and one that's pretty hard to mimic with straight JavaScript and plain objects) is that array instances maintain the length property so that it reflects one plus the numeric value of the property whose name is numeric and whose value, when converted to a number, is the largest of all such properties. That sounds really weird, but it just means that given an array instance, the properties with names like "0", "5", "207", and so on, are all treated specially in that their existence determines the value of length. And, on top of that, the value of length can be set to remove such properties. Setting the length of an array to 0 effectively removes all properties whose names look like whole numbers.

OK, so that's what makes an array special. All of that, however, has nothing at all to do with how the JavaScript [ ] operator works. That operator is an object property access mechanism which works on any object. It's important to note in that regard that numeric array property names are not special as far as simple property access goes. They're just strings that happen to look like numbers, but JavaScript object property names can be any sort of string you like.

Thus, the way the [ ] operator works in a for loop iterating through an array:

for (var i = 0; i < myArray.length; ++i) {
  var value = myArray[i]; // property access
  // ...
}

is really no different from the way [ ] works when accessing a property whose name is some computed string:

var value = jsObj["key" + i];

The [ ] operator there is doing precisely the same thing in both instances. The fact that in one case the object involved happens to be an array is unimportant, in other words.

When setting property values using [ ], the story is the same except for the special behavior around maintaining the length property. If you set a property with a numeric key on an array instance:

myArray[200] = 5;

then (assuming that "200" is the biggest numeric property name) the length property will be updated to 201 as a side-effect of the property assignment. If the same thing is done to a plain object, however:

myObj[200] = 5;

there's no such side-effect. The property called "200" of both the array and the object will be set to the value 5 in otherwise the exact same way.

One might think that because that length behavior is kind-of handy, you might as well make all objects instances of the Array constructor instead of plain objects. There's nothing directly wrong about that (though it can be confusing, especially for people familiar with some other languages, for some properties to be included in the length but not others). However, if you're working with JSON serialization (a fairly common thing), understand that array instances are serialized to JSON in a way that only involves the numerically-named properties. Other properties added to the array will never appear in the serialized JSON form. So for example:

var obj = [];
obj[0] = "hello world";
obj["something"] = 5000;

var objJSON = JSON.stringify(obj);

the value of "objJSON" will be a string containing just ["hello world"]; the "something" property will be lost.

ES2015:

If you're able to use ES6 JavaScript features, you can use Computed Property Names to handle this very easily:

var key = 'DYNAMIC_KEY',
    obj = {
        [key]: 'ES6!'
    };

console.log(obj);
// > { 'DYNAMIC_KEY': 'ES6!' }

Compiling with -source 1.5 -target 1.5 (in a JDK 6 environment) will honor only language elements that were in 1.5 and prior. Great. But there were no language changes in 6 anyway. Problem with this approach (on Mac with 1.6) is that using classes that came AFTER 1.5 will still compile because they exist in the rt.jar. So one could run in a 1.5 env and get a class not found exception with no prior warning when compiling. I found this out the hard way with javax.swing.event.RowSorterEvent/Listener. Both entered "Since 1.6" but are not caught with -source 1.5

$image is in your case the value of the item and not the key. Use the following syntax to get the key too:

foreach ($images as $key => $value) {
    /* … */
}

Now you can delete the item with unset($images[$key]).

you can use tcpdump on the server to check if the client even reaches the server.

  tcpdump -i any tcp port 9100

also make sure your firewall is not blocking incoming connections.

EDIT: you can also write the dump into a file and view it with wireshark on your client if you don't want to read it on the console.

2nd Edit: you can check if you can reach the port via

 nc ip 9100 -z -v

from your local PC.

To check third version, we can use,

python3 --version

You can do it so simply by

String newMysz = mysz.replace(" ","");

A little late reply, but what I found in Notepad++ v7.8.6 is, on RMB (Right Mouse Button), on selection text, it gives an option called "Style token" where it shows "Using 1st/2nd/3rd/4th/5th style" to highlight the selected text in different pre-defined colors

Use enumerate():

>>> S = [1,30,20,30,2]
>>> for index, elem in enumerate(S):
        print(index, elem)

(0, 1)
(1, 30)
(2, 20)
(3, 30)
(4, 2)

1) paste the myapp.apk in platform-tools folder , in my case C:\Users\mazbizxam\AppData\Local\Android\android-sdk\platform-tools, this is the link in my case it may change to you people

2)open the directory in CMD CD C:\Users\mazbizxam\AppData\Local\Android\android-sdk\platform-tools

3)Now you are in platform-tools folder , just type adb install myapp.apk

please ensure that your emulator is turn on , if every thing is ok apk will install

if takes a command and checks its return value. [ is just a command.

if grep -q ...

You need To use then() function, like this

swal({
    title: "Are you sure?",
    text: "You will not be able to recover this imaginary file!",
    type: "warning",
    showCancelButton: true,
    confirmButtonColor: '#DD6B55',
    confirmButtonText: 'Yes, I am sure!',
    cancelButtonText: "No, cancel it!"
 }).then(
       function () { /*Your Code Here*/ },
       function () { return false; });

Create the hash:

hash = {:item1 => 1}

Add a new item to it:

hash[:item2] = 2

ORDER BY is always last...

However, you need to pick the fields you ACTUALLY WANT then select only those and group by them. SELECT * and GROUP BY Email will give you RANDOM VALUES for all the fields but Email. Most RDBMS will not even allow you to do this because of the issues it creates, but MySQL is the exception.

SELECT Email, COUNT(*)
FROM user_log
GROUP BY Email
HAVING COUNT(*) > 1
ORDER BY UpdateDate DESC

Use a view model that contains multiple view models:

   namespace MyProject.Web.ViewModels
   {
      public class UserViewModel
      {
          public UserDto User { get; set; }
          public ProductDto Product { get; set; }
          public AddressDto Address { get; set; }
      }
   }

In your view:

  @model MyProject.Web.ViewModels.UserViewModel

  @Html.LabelFor(model => model.User.UserName)
  @Html.LabelFor(model => model.Product.ProductName)
  @Html.LabelFor(model => model.Address.StreetName)

here is a good solution:

CREATE function [dbo].[inLineMax] (@v1 float,@v2 float,@v3 float,@v4 float)
returns float
as
begin
declare @val float
set @val = 0 
declare @TableVal table
(value float )
insert into @TableVal select @v1
insert into @TableVal select @v2
insert into @TableVal select @v3
insert into @TableVal select @v4

select @val= max(value) from @TableVal

return @val
end 

You can use Linq to XML to do this:

XDocument doc = XDocument.Load("input.xml");
var q = from node in doc.Descendants("Setting")
        let attr = node.Attribute("name")
        where attr != null && attr.Value == "File1"
        select node;
q.ToList().ForEach(x => x.Remove());
doc.Save("output.xml");

According to the Cloudera documentation - What's New in CDH 5.7.0 it includes Spark 1.6.0.

I've found that this error is also generated if the document is empty. In this case it's also because there is no root element - but the error message "Extra content and the end of the document" is misleading in this situation.

You can use the IndexOf method and the Substring method like so:

string output = input.Substring(input.IndexOf('.') + 1);

The above doesn't have error handling, so if a period doesn't exist in the input string, it will present problems.

From what I know I don't believe that Chart.JS has any functionality to help for drawing text on a pie chart. But that doesn't mean you can't do it yourself in native JavaScript. I will give you an example on how to do that, below is the code for drawing text for each segment in the pie chart:

function drawSegmentValues()
{
    for(var i=0; i<myPieChart.segments.length; i++) 
    {
        // Default properties for text (size is scaled)
        ctx.fillStyle="white";
        var textSize = canvas.width/10;
        ctx.font= textSize+"px Verdana";

        // Get needed variables
        var value = myPieChart.segments[i].value;
        var startAngle = myPieChart.segments[i].startAngle;
        var endAngle = myPieChart.segments[i].endAngle;
        var middleAngle = startAngle + ((endAngle - startAngle)/2);

        // Compute text location
        var posX = (radius/2) * Math.cos(middleAngle) + midX;
        var posY = (radius/2) * Math.sin(middleAngle) + midY;

        // Text offside to middle of text
        var w_offset = ctx.measureText(value).width/2;
        var h_offset = textSize/4;

        ctx.fillText(value, posX - w_offset, posY + h_offset);
    }
}

A Pie Chart has an array of segments stored in PieChart.segments, we can look at the startAngle and endAngle of these segments to determine the angle in between where the text would be middleAngle. Then we would move in that direction by Radius/2 to be in the middle point of the chart in radians.

In the example above some other clean-up operations are done, due to the position of text drawn in fillText() being the top right corner, we need to get some offset values to correct for that. And finally textSize is determined based on the size of the chart itself, the larger the chart the larger the text.

Fiddle Example

With some slight modification you can change the discrete number values for a dataset into the percentile numbers in a graph. To do this get the total value of the items in your dataset, call this totalValue. Then on each segment you can find the percent by doing:

Math.round(myPieChart.segments[i].value/totalValue*100)+'%';

The section here myPieChart.segments[i].value/totalValue is what calculates the percent that the segment takes up in the chart. For example if the current segment had a value of 50 and the totalValue was 200. Then the percent that the segment took up would be: 50/200 => 0.25. The rest is to make this look nice. 0.25*100 => 25, then we add a % at the end. For whole number percent tiles I rounded to the nearest integer, although can can lead to problems with accuracy. If we need more accuracy you can use .toFixed(n) to save decimal places. For example we could do this to save a single decimal place when needed:

var value = myPieChart.segments[i].value/totalValue*100;
if(Math.round(value) !== value)
    value = (myPieChart.segments[i].value/totalValue*100).toFixed(1);
value = value + '%';

You can use eval() for this purpose

>>> url = "'http address'"
>>> eval(url)
'http address'

while eval() poses risk , i think in this context it is safe.

The targetNamespace of your XML Schema does not match the namespace of the Root element (dot in Test.Namespace vs. comma in Test,Namespace)

Once you make the above agree, you have to consider that your element2 has an attribute order that is not in your XSD.

1. Go to your project root directory cd example /home/ubuntu/react-js
2. Build your project first npm run build

3. check your build directory gracefully all the files will be available in the build folder.

   asset-manifest.json

   favicon.ico

   manifest.json

   robots.txt

   static assets

   index.html

   precache-manifest.ddafca92870314adfea99542e1331500.js service-worker.js

4.copy the build folder to your apache server i.e /var/www/html

sudo cp -rf build /var/www/html

5. go to sites-available directory

   cd /etc/apache2/sites-available/

6. open 000-default.conf file

   sudo vi 000-default.conf and rechange the DocumentRoot path

   enter image description here

7. Now goto apache conf.

   cd /etc/aapche2

   sudo vi apache2.conf

   add the given snippet

<Directory /var/www/html>_x000D_

    </Directory>

8. make a file inside /var/www/html/build

   sudo vi .htaccess

Options -MultiViews_x000D_

Springboot (via Spring) now makes adding to existing resource handlers easy. See Dave Syers answer. To add to the existing static resource handlers, simply be sure to use a resource handler path that doesn't override existing paths.

The two "also" notes below are still valid.

. . .

[Edit: The approach below is no longer valid]

If you want to extend the default static resource handlers, then something like this seems to work:

@Configuration
@AutoConfigureAfter(DispatcherServletAutoConfiguration.class)
public class CustomWebMvcAutoConfig extends
                    WebMvcAutoConfiguration.WebMvcAutoConfigurationAdapter {

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    String myExternalFilePath = "file:///C:/Temp/whatever/m/";

    registry.addResourceHandler("/m/**").addResourceLocations(myExternalFilePath);

    super.addResourceHandlers(registry);
  }

}

The call to super.addResourceHandlers sets up the default handlers.

Also:

• Note the trailing slash on the external file path. (Depends on your expectation for URL mappings).
• Consider reviewing the source code of WebMvcAutoConfigurationAdapter.

I think this should work...

var query = from m in context.MyTable
            where m.MyContainerId == '1' // or what ever the foreign key name is...
            select m;

var count = query.Count();

Here's a very pragmatic idiom:

(cd $dir) || return # Is this a directory,
                    # and do we have access?

I typically wrap it in a function:

can_use_as_dir() {
    (cd ${1:?pathname expected}) || return
}

Or:

assert_dir_access() {
    (cd ${1:?pathname expected}) || exit
}

The nice thing about this approach is that I do not have to think of a good error message.

cd will give me a standard one line message to standard error already. It will also give more information than I will be able to provide. By performing the cd inside a subshell ( ... ), the command does not affect the current directory of the caller. If the directory exists, this subshell and the function are just a no-op.

Next is the argument that we pass to cd: ${1:?pathname expected}. This is a more elaborate form of parameter substitution which is explained in more detail below.

Tl;dr: If the string passed into this function is empty, we again exit from the subshell ( ... ) and return from the function with the given error message.

Quoting from the ksh93 man page:

${parameter:?word}

If parameter is set and is non-null then substitute its value; otherwise, print word and exit from the shell (if not interactive). If word is omitted then a standard message is printed.

and

If the colon : is omitted from the above expressions, then the shell only checks whether parameter is set or not.

The phrasing here is peculiar to the shell documentation, as word may refer to any reasonable string, including whitespace.

In this particular case, I know that the standard error message 1: parameter not set is not sufficient, so I zoom in on the type of value that we expect here - the pathname of a directory.

A philosophical note:

The shell is not an object oriented language, so the message says pathname, not directory. At this level, I'd rather keep it simple - the arguments to a function are just strings.

Here is a part of my code that parse JSON, it may be helpful for you:

         return this.http.get("./file.json")

I know this question is already answered but I have one solution for this same.

You can also use Object.keys() inside of *ngFor to get required result.

I have created a demo on stackblitz. I hope this will help/guide to you/others.

I recently ran into this issue for on old repo on my machine that had been pushed up using https. steps 5 and 6 solved my issue by re-setting the remote url for my repo from using the https url to the ssh url

checking the remote is using the https url

> git remote -v
origin  https://github.com/ExampleUser/ExampleRepo.git (fetch)
origin  https://github.com/ExampleUser/ExampleRepo.git (push)

then re-setting the origin to use the ssh url

> git remote set-url origin [email protected]:ExampleUser/ExampleRepo.git

verifying new remote

> git remote -v
origin  [email protected]:ExampleUser/ExampleRepo.git (fetch)
origin  [email protected]:ExampleUser/ExampleRepo.git (push)

could now successfully git push -u origin

i'm still not sure what setting i would have changed that might have caused the push to fail when the remote is https but this was the solution to my issue

Here's an example using http://www.geoplugin.net/json.gp

$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip={$ip}"));
echo $details;

XmlDocument doc = new XmlDocument();

    foreach (XmlNode item in prop)

What is happening is that Angular-translate is watching the expression with an event-based system, and just as in any other case of binding or two-way binding, an event is fired when the data is retrieved, and the value changed, which obviously doesn't work for translation. Translation data, unlike other dynamic data on the page, must, of course, show up immediately to the user. It can't pop in after the page loads.

Even if you can successfully debug this issue, the bigger problem is that the development work involved is huge. A developer has to manually extract every string on the site, put it in a .json file, manually reference it by string code (ie 'pageTitle' in this case). Most commercial sites have thousands of strings for which this needs to happen. And that is just the beginning. You now need a system of keeping the translations in synch when the underlying text changes in some of them, a system for sending the translation files out to the various translators, of reintegrating them into the build, of redeploying the site so the translators can see their changes in context, and on and on.

Also, as this is a 'binding', event-based system, an event is being fired for every single string on the page, which not only is a slower way to transform the page but can slow down all the actions on the page, if you start adding large numbers of events to it.

Anyway, using a post-processing translation platform makes more sense to me. Using GlobalizeIt for example, a translator can just go to a page on the site and start editing the text directly on the page for their language, and that's it: https://www.globalizeit.com/HowItWorks. No programming needed (though it can be programmatically extensible), it integrates easily with Angular: https://www.globalizeit.com/Translate/Angular, the transformation of the page happens in one go, and it always displays the translated text with the initial render of the page.

Full disclosure: I'm a co-founder :)

Here's one using regex just for fun:

boolean isRotation(String s1, String s2) {
   return (s1.length() == s2.length()) && (s1 + s2).matches("(.*)(.*)\\2\\1");
}

You can make it a bit simpler if you can use a special delimiter character guaranteed not to be in either strings.

boolean isRotation(String s1, String s2) {
   // neither string can contain "="
   return (s1 + "=" + s2).matches("(.*)(.*)=\\2\\1");
}

You can also use lookbehind with finite repetition instead:

boolean isRotation(String s1, String s2) {
   return (s1 + s2).matches(
      String.format("(.*)(.*)(?<=^.{%d})\\2\\1", s1.length())
   );
}

I like the versatility of jEdit (http://www.jedit.org), its got a lot of plugins, crossplatform and has also stuff like block selection which I use all the time.

The downside is, because it is written in java, it is not the fastest one.

Carbon could also be a nice way to go.

From their website:

A simple PHP API extension for DateTime. http://carbon.nesbot.com/

Example:

use Carbon\Carbon;

//...

$day1 = Carbon::createFromFormat('Y-m-d H:i:s', '2006-04-12 12:30:00');
$day2 = Carbon::createFromFormat('Y-m-d H:i:s', '2006-04-14 11:30:00');

echo $day1->diffInHours($day2); // 47

//...

Carbon extends the DateTime class to inherit methods including diff(). It adds nice sugars like diffInHours, diffInMintutes, diffInSeconds e.t.c.

I got a MD5 hash with different results for both key and certificate.

This says it all. You have a mismatch between your key and certificate.

The modulus should match. Make sure you have correct key.

You are trying to pass pointers (which you do not delete, thus leaking memory) where references are needed. You do not really need pointers here:

Complex firstComplexNumber(81, 93);
Complex secondComplexNumber(31, 19);

cout << "Numarul complex este: " << firstComplexNumber << endl;
//                                  ^^^^^^^^^^^^^^^^^^ No need to dereference now

Improving the answer https://stackoverflow.com/a/14720445/6654512 to work with Python3. That piece of code would sometimes generate numbers greater than 1 and matplotlib would throw an error.

for X,Y in data:
   scatter(X, Y, c=numpy.random.random(3))

There is an option in Postman if you download it from https://www.getpostman.com instead of the chrome store (most probably it has been introduced in the new versions and the chrome one will be updated later) not sure about the old ones.

In the settings, turn off the SSL certificate verification option

Be sure to remember to reactivate it afterwards, this is a security feature.

If you really want to use the chrome app, you could always add an exception to chrome for the url: Enter the url you would like to open in the chrome browser, you'll get a warning with a link at the bottom of the page to add an exception, which if you do, it will also allow postman to access your url. But the first option of using the postman stand-alone app is much better.

I hope this can help.

Easiest way is to just create an Item Decoration for your RecyclerView.

import android.graphics.Canvas;
import android.graphics.Rect;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;

private final SectionCallback sectionCallback;

private View     headerView;

public RecyclerSectionItemDecoration(int headerHeight, boolean sticky, @NonNull SectionCallback sectionCallback) {
    headerOffset = headerHeight;
    this.sticky = sticky;
    this.sectionCallback = sectionCallback;
}

@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
    super.getItemOffsets(outRect, view, parent, state);

    int pos = parent.getChildAdapterPosition(view);
    if (sectionCallback.isSection(pos)) {
        outRect.top = headerOffset;
    }
}

@Override

    CharSequence previousHeader = "";
    for (int i = 0; i < parent.getChildCount(); i++) {
        View child = parent.getChildAt(i);
        final int position = parent.getChildAdapterPosition(child);

        CharSequence title = sectionCallback.getSectionHeader(position);
        header.setText(title);
        if (!previousHeader.equals(title) || sectionCallback.isSection(position)) {
            drawHeader(c,

            previousHeader = title;
        }
    }
}

private void drawHeader(Canvas c, View child, View headerView) {
    c.save();
    if (sticky) {
        c.translate(0,
                    Math.max(0,
                             child.getTop() - headerView.getHeight()));
    } else {

                    child.getTop() - headerView.getHeight());
    }
    headerView.draw(c);
    c.restore();
}

private View inflateHeaderView(RecyclerView parent) {
    return LayoutInflater.from(parent.getContext())
                         .inflate(R.layout.recycler_section_header,
                                  parent,
                                  false);
}

/**

 */
private void fixLayoutSize(View view, ViewGroup parent) {
    int widthSpec = View.MeasureSpec.makeMeasureSpec(parent.getWidth(),
                                                     View.MeasureSpec.EXACTLY);
    int heightSpec = View.MeasureSpec.makeMeasureSpec(parent.getHeight(),
                                                      View.MeasureSpec.UNSPECIFIED);

    int childWidth = ViewGroup.getChildMeasureSpec(widthSpec,
                                                   parent.getPaddingLeft() + parent.getPaddingRight(),

    view.layout(0,
                0,
                view.getMeasuredWidth(),
                view.getMeasuredHeight());
}

public interface SectionCallback {

    boolean isSection(int position);

    CharSequence getSectionHeader(int position);
}

}

XML for your header in recycler_section_header.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/list_item_section_text"
    android:layout_width="match_parent"
    android:layout_height="@dimen/recycler_section_header_height"
    android:background="@android:color/black"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:textColor="@android:color/white"
    android:textSize="14sp"
/>

And finally to add the Item Decoration to your RecyclerView:

RecyclerSectionItemDecoration sectionItemDecoration =
        new RecyclerSectionItemDecoration(getResources().getDimensionPixelSize(R.dimen.recycler_section_header_height),
                                          true, // true for sticky, false for not
                                          new RecyclerSectionItemDecoration.SectionCallback() {
                                              @Override
                                              public boolean isSection(int position) {
                                                  return position == 0
                                                      || people.get(position)
                                                               .getLastName()
                                                               .charAt(0) != people.get(position - 1)
                                                                                   .getLastName()
                                                                                   .charAt(0);
                                              }

                                              @Override
                                              public CharSequence getSectionHeader(int position) {
                                                  return people.get(position)
                                                               .getLastName()
                                                               .subSequence(0,
                                                                            1);
                                              }
                                          });
    recyclerView.addItemDecoration(sectionItemDecoration);

With this Item Decoration you can either make the header pinned/sticky or not with just a boolean when creating the Item Decoration.

You can find a complete working example on github: https://github.com/paetztm/recycler_view_headers

I do like below to :

var book: MutableList<Books> = mutableListOf()

/** Returns a new [MutableList] with the given elements. */

public fun <T> mutableListOf(vararg elements: T): MutableList<T>
    = if (elements.size == 0) ArrayList() else ArrayList(ArrayAsCollection(elements, isVarargs = true))

In the model, write the below code;

public $timestamps = false;

This would work.

Explanation : By default laravel will expect created_at & updated_at column in your table. By making it to false it will override the default setting.

To be safe you don't break stuff (for example when these strings are changed in your code or further up), or crash you program (in case the returned string was literal for example like "hello I'm a literal string" and you start to edit it), make a copy of the returned string.

You could use strdup() for this, but read the small print. Or you can of course create your own version if it's not there on your platform.

It's easier to use the timestamp for this things since Tweepy gets both

import datetime
print(datetime.datetime.fromtimestamp(int(t1)).strftime('%H:%M'))

Usually I will just use the undocumented proc sp_MSForEachTable

-- disable referential integrity
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL' 
GO 

EXEC sp_MSForEachTable 'TRUNCATE TABLE ?' 
GO 

-- enable referential integrity again 
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL' 
GO

See also: Delete all data in database (when you have FKs)

You have a string representing a JSON serialized JavaScript object. You need to deserialize it back to a JavaScript object before being able to loop through its properties. Otherwise you will be looping through each individual character of this string.

var resultJSON = '{"FirstName":"John","LastName":"Doe","Email":"[email protected]","Phone":"123 dead drive"}';
var result = $.parseJSON(resultJSON);
$.each(result, function(k, v) {
    //display the key and value pair
    alert(k + ' is ' + v);
});

Live demo.

do the one of these.

   if(!statusCheck.equals("success"))
    {
        //do something
    }

      or

    if(!"success".equals(statusCheck))
    {
        //do something
    }

If you know the kernel file is installed on your machine, then problem is getting emulator.exe to find it.

My fix was based on the post by user2789389. I could launch the AVD from the AVD Manager, but not from the command line. So, using AVD Manager, I selected the avd I wanted to run and clicked "Details". That showed me the path to the avd definition file. Within a folder of the same name, next to this .avd file, I found a config.ini file. In the ini, I found the following line:

image.sysdir.1=system-images\android-19\default\armeabi-v7a\

I looked in the folder C:\Users\XXXX\android-sdks\system-images\android-19, and found that the image.sysdir.1 path was invalid. I had to remove the "default" sub folder, thus changing it to the following:

image.sysdir.1=system-images\android-19\armeabi-v7a\

I saved the ini and tried again to launch the AVD. That fixed the problem!

I know this question is resolved but, for the benefit of anyone else reading it; if you have all of the types involved as strings, you could do this as a one liner:

IYourInterface o = (Activator.CreateInstance(Type.GetType("Namespace.TaskA`1[OtherNamespace.TypeParam]") as IYourInterface);

Whenever I've done this kind of thing, I've had an interface which I wanted subsequent code to utilise, so I've casted the created instance to an interface.

You can always append the '%' by itself without any other format specifiers in the string you are appending, like so...

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [stringTest stringByAppendingString:@"%"];
NSLog(@"%@", stringTest);

For iOS7.0+

To expand the answer to other characters that might cause you conflict you may choose to use:

- (NSString *)stringByAddingPercentEncodingWithAllowedCharacters:(NSCharacterSet *)allowedCharacters

Written out step by step it looks like this:

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [[stringTest stringByAppendingString:@"%"] 
             stringByAddingPercentEncodingWithAllowedCharacters:
             [NSCharacterSet alphanumericCharacterSet]];
stringTest = [stringTest stringByRemovingPercentEncoding];

NSLog(@"percent value of test: %@", stringTest);

Or short hand:

NSLog(@"percent value of test: %@", [[[[NSString stringWithFormat:@"%d", test] 
stringByAppendingString:@"%"] stringByAddingPercentEncodingWithAllowedCharacters:
[NSCharacterSet alphanumericCharacterSet]] stringByRemovingPercentEncoding]);

Thanks to all the original contributors. Hope this helps. Cheers!

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "file/to/transfer";

    Session session = null;
    Channel channel = null;
    ChannelSftp channelSftp = null;
    System.out.println("preparing the host information for sftp.");

    try {
        JSch jsch = new JSch();
        session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
        session.setPassword(SFTPPASS);
        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        System.out.println("Host connected.");
        channel = session.openChannel("sftp");
        channel.connect();
        System.out.println("sftp channel opened and connected.");
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd(SFTPWORKINGDIR);
        File f = new File(fileName);
        channelSftp.put(new FileInputStream(f), f.getName());
        log.info("File transfered successfully to host.");
    } catch (Exception ex) {
        System.out.println("Exception found while tranfer the response.");
    } finally {
        channelSftp.exit();
        System.out.println("sftp Channel exited.");
        channel.disconnect();
        System.out.println("Channel disconnected.");
        session.disconnect();
        System.out.println("Host Session disconnected.");
    }
}   

As of version 3.0.0, you can get the current route by calling:

this.context.router.location.pathname

Sample code is below:

var NavLink = React.createClass({
    contextTypes: {
        router: React.PropTypes.object
    },

    render() {   
        return (
            <Link {...this.props}></Link>
        );
    }
});

You didn't mention if you are using Excel 2003 or 2007, but you may run into an issue with the # of rows in Excel 2003 being capped at 65,536. If you are using 2007, the limit is 1,048,576.

Also, can I ask what your end goal is for your analysis? If you need to perform many statistical calculations on your data, I would recommend moving out of the Excel environment into something that is more directly suited for data manipulation and analysis, such as R.

There are a variety of options for connecting R to Excel, including

1. RExcel
2. RODBC
3. Other options in the R manual

Regardless of what you choose to use to move data in/out of R, the code to change from wide to long format is pretty trivial. I enjoy the melt() function from the reshape package. That code would look like:

library(reshape)
#Fake data, 4 columns, 20k rows
df <- data.frame(foo = rnorm(20000)
    , bar = rlnorm(20000)
    , fee = rnorm(20000)
    , fie = rlnorm(20000)
)
#Create new object with 1 column, 80k rows
df.m <- melt(df)

From there, you can perform any number of statistical or graphing operations. If you use the RExcel plugin above, you can fire all of this up and run it within Excel itself. The R community is very active and can help address any and all questions you may encounter.

Good luck!

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

<Style TargetType="{x:Type TabItem}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabItem}">
        <Grid>
          <Border Name="Border" Margin="0,0,0,0" Background="Transparent"
                  BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
            <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
                              HorizontalAlignment="Center"
                              ContentSource="Header" Margin="12,2,12,2"
                              RecognizesAccessKey="True">

Check you routes, the update on 9/28/2014 impacted us. We had to adjust our older servers and add new routes. Here is the article http://www.rackspace.com/knowledge_center/article/updating-servicenet-routes-on-cloud-servers-created-before-june-3-2013

Here's my take on this in case anyone comes across this thread:

This helps protect against non-numerical data destroying either of your final variables that determine lat and lng.

It works by taking in all of your coordinates, parsing them into separate lat and lng elements of an array, then determining the average of each. That average should be the center (and has proven true in my test cases.)

var coords = "50.0160001,3.2840073|50.014458,3.2778274|50.0169713,3.2750587|50.0180745,3.276742|50.0204038,3.2733474|50.0217796,3.2781737|50.0293064,3.2712542|50.0319918,3.2580816|50.0243287,3.2582281|50.0281447,3.2451177|50.0307925,3.2443178|50.0278165,3.2343882|50.0326574,3.2289809|50.0288569,3.2237612|50.0260081,3.2230589|50.0269495,3.2210104|50.0212645,3.2133541|50.0165868,3.1977592|50.0150515,3.1977341|50.0147901,3.1965286|50.0171915,3.1961636|50.0130074,3.1845098|50.0113267,3.1729483|50.0177206,3.1705726|50.0210692,3.1670394|50.0182166,3.158297|50.0207314,3.150927|50.0179787,3.1485753|50.0184944,3.1470782|50.0273077,3.149845|50.024227,3.1340514|50.0244172,3.1236235|50.0270676,3.1244474|50.0260853,3.1184879|50.0344525,3.113806";

      if (isNaN(Number(centerCoordsArray[0]))) {

Quick-to-write alterantive

Even though is not the fastest choice, if performance is not an issue you can use:

sum(~np.isnan(data)).

Performance:

In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop

In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop

In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop

Question is old, but it's never too late to answer.

$(document).ready(function() {
  //prevent drag and drop
  const yourInput = document.getElementById('inputid');
  yourInput.ondrop = e => e.preventDefault();

  //prevent paste
  const Input = document.getElementById('inputid');
  Input.onpaste = e => e.preventDefault();
});

Key is df.setLenient(false);. This is more than enough for simple cases. If you are looking for a more robust (I doubt) and/or alternate libraries like joda-time then look at the answer by the user "tardate"

final static String DATE_FORMAT = "dd-MM-yyyy";

public static boolean isDateValid(String date) 
{
        try {
            DateFormat df = new SimpleDateFormat(DATE_FORMAT);
            df.setLenient(false);
            df.parse(date);
            return true;
        } catch (ParseException e) {
            return false;
        }
}

For Western Arabic numbers (0-9):

$words = preg_replace('/[0-9]+/', '', $words);

For all numerals including Western Arabic (e.g. Indian):

$words = '????';
$words = preg_replace('/\d+/u', '', $words);
var_dump($words); // string(0) ""

• \d+ matches multiple numerals.
• The modifier /u enables unicode string treatment. This modifier is important, otherwise the numerals would not match.

#!/bin/bash

read -p "Enter a directory: " BASEPATH

SUBFOLD1=${BASEPATH%%/}/subFold1
SUBFOLD2=${BASEPATH%%/}/subFold2

echo "I will create $SUBFOLD1 and $SUBFOLD2"

# mkdir -p $SUBFOLD1
# mkdir -p $SUBFOLD2

And if you want to use readline so you get completion and all that, add a -e to the call to read:

read -e -p "Enter a directory: " BASEPATH

If you are lucky enough to develop on Kotlin, just create an extension function:

fun String.toSpanned(): Spanned {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return Html.fromHtml(this, Html.FROM_HTML_MODE_LEGACY)
    } else {
        @Suppress("DEPRECATION")
        return Html.fromHtml(this)
    }
}

And then it's so sweet to use it everywhere:

yourTextView.text = anyString.toSpanned()

Had a simular issue getting the same exception. Took some time locating. In my case I had a static utility class with a constructor that threw the exception (wrapping it). So my issue was in the static constructor.

With my ASP.NET Core Angular project running in Visual Studio 2019, sometimes I get this error message in the Firefox console:

Content Security Policy: The page’s settings blocked the loading of a resource at inline (“default-src”).

In Chrome, the error message is instead:

Failed to load resource: the server responded with a status of 404 ()

In my case it had nothing to do with my Content Security Policy, but instead was simply the result of a TypeScript error on my part.

Check your IDE output window for a TypeScript error, like:

> ERROR in src/app/shared/models/person.model.ts(8,20): error TS2304: Cannot find name 'bool'.
>
> i ?wdm?: Failed to compile.

_{Note: Since this question is the first result on Google for this error message.}

This happens to me occasionally, usually it's just a simple oversight. Just pay attention to details, simple typos, etc. For example when copy/pasting import statements, like this:

I've my project in github and heroku, for upload an heroku use :

heroku git:remote -a <project>

The doc it is:

I was just wondering how the random number generator in C# works.

That's implementation-specific, but the wikipedia entry for pseudo-random number generators should give you some ideas.

I was also curious how I could make a program that generates random WHOLE INTEGER numbers from 1-100.

You can use Random.Next(int, int):

Random rng = new Random();
for (int i = 0; i < 10; i++)
{
    Console.WriteLine(rng.Next(1, 101));
}

Note that the upper bound is exclusive - which is why I've used 101 here.

You should also be aware of some of the "gotchas" associated with Random - in particular, you should not create a new instance every time you want to generate a random number, as otherwise if you generate lots of random numbers in a short space of time, you'll see a lot of repeats. See my article on this topic for more details.

JUNG is a good option for visualisation, and also has a fairly good set of available graph algorithms, including several different mechanisms for random graph creation, rewiring, etc. I've also found it to be generally fairly easy to extend and adapt where necessary.

In one line, using Java 8:

list.sort(Comparator.naturalOrder());

You can increase security in authentication process by using JWT (JSON Web Tokens) and SSL/HTTPS.

The Basic Auth / Session ID can be stolen via:

• MITM attack (Man-In-The-Middle) - without SSL/HTTPS
• An intruder gaining access to a user's computer
• XSS

By using JWT you're encrypting the user's authentication details and storing in the client, and sending it along with every request to the API, where the server/API validates the token. It can't be decrypted/read without the private key (which the server/API stores secretly) Read update.

The new (more secure) flow would be:

Login

• User logs in and sends login credentials to API (over SSL/HTTPS)
• API receives login credentials
• If valid:
  • Register a new session in the database Read update
  • Encrypt User ID, Session ID, IP address, timestamp, etc. in a JWT with a private key.
• API sends the JWT token back to the client (over SSL/HTTPS)
• Client receives the JWT token and stores in localStorage/cookie

Every request to API

• User sends a HTTP request to API (over SSL/HTTPS) with the stored JWT token in the HTTP header
• API reads HTTP header and decrypts JWT token with its private key
• API validates the JWT token, matches the IP address from the HTTP request with the one in the JWT token and checks if session has expired
• If valid:
  • Return response with requested content
• If invalid:
  • Throw exception (403 / 401)
  • Flag intrusion in the system
  • Send a warning email to the user.

Updated 30.07.15:

JWT payload/claims can actually be read without the private key (secret) and it's not secure to store it in localStorage. I'm sorry about these false statements. However they seem to be working on a JWE standard (JSON Web Encryption).

I implemented this by storing claims (userID, exp) in a JWT, signed it with a private key (secret) the API/backend only knows about and stored it as a secure HttpOnly cookie on the client. That way it cannot be read via XSS and cannot be manipulated, otherwise the JWT fails signature verification. Also by using a secure HttpOnly cookie, you're making sure that the cookie is sent only via HTTP requests (not accessible to script) and only sent via secure connection (HTTPS).

Updated 17.07.16:

JWTs are by nature stateless. That means they invalidate/expire themselves. By adding the SessionID in the token's claims you're making it stateful, because its validity doesn't now only depend on signature verification and expiry date, it also depends on the session state on the server. However the upside is you can invalidate tokens/sessions easily, which you couldn't before with stateless JWTs.

This works for me:

val personsMap = persons.foldLeft(scala.collection.mutable.Map[Int, PersonDTO]()) {
    (m, p) => m(p.id) = p; m
}

The Map has to be mutable and the Map has to be return since adding to a mutable Map does not return a map.

<button type="button" id="popover2" title="" data-content="<div id='my_popover' style='height:250px;width:300px;overflow:auto;'>Loading...Please Wait</div>" data-html="true" data-toggle="popover2" class="btn btn-primary" data-original-title="A Title">Tags</button>

$('#popover2').popover({ 
    html : true,
    title: null,
    trigger: "click",
    placement:"right"
});

$("#popover2").on('shown.bs.popover', function(){
    $('#my_popover').html("dynamic content loaded");

});

SELECT * FROM items WHERE `items.xml` LIKE '%123456%'

The % operator in LIKE means "anything can be here".

RouterModule.forRoot([
      { path: 'welcome', component: WelcomeComponent },
      { path: '', redirectTo: 'welcome', pathMatch: 'full' },
      { path: '**', component: 'pageNotFoundComponent' }
    ])

Case 1 pathMatch:'full': In this case, when app is launched on localhost:4200 (or some server) the default page will be welcome screen, since the url will be https://localhost:4200/

If https://localhost:4200/gibberish this will redirect to pageNotFound screen because of path:'**' wildcard

Case 2 pathMatch:'prefix':

If the routes have { path: '', redirectTo: 'welcome', pathMatch: 'prefix' }, now this will never reach the wildcard route since every url would match path:'' defined.

Copied and pasted from http://www.w3schools.com, there is no need for the JQuery overhead.

var person = {fname:"John", lname:"Doe", age:25};

var text = "";
var x;
for (x in person) {
    text += person[x];
}

RESULT: John Doe 25

This is called ACF(Automatic Content Filter) in ckeditor.It remove all unnessary tag's What we are using in text content.Using this command in your config.js file should be turn off this ACK.

config.allowedContent = true;

Wrapping a <a> around won't work (unless you set the <div> to display:inline-block; or display:block; to the <a>) because the div is s a block-level element and the <a> is not.

<a href="http://www.example.com" style="display:block;">
   <div>
       content
   </div>
</a>

<a href="http://www.example.com">
   <div style="display:inline-block;">
       content
   </div>
</a>

<a href="http://www.example.com">
   <span>
       content
   </span >
</a>

<a href="http://www.example.com">
   content
</a>

But maybe you should skip the <div> and choose a <span> instead, or just the plain <a>. And if you really want to make the div clickable, you could attach a javascript redirect with a onclick handler, somethign like:

document.getElementById("myId").setAttribute('onclick', 'location.href = "url"'); 

but I would recommend against that.

Below solution perfectly works for spring boot application.

Controller:

@GetMapping("user/getAllInactiveUsers")
List<User> getAllInactiveUsers(@RequestParam("date") @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date dateTime) {
    return userRepository.getAllInactiveUsers(dateTime);
}

So in the caller (in my case its a web flux), we need to pass date time in this("yyyy-MM-dd HH:mm:ss") format.

Caller Side:

public Flux<UserDto> getAllInactiveUsers(String dateTime) {
    Flux<UserDto> userDto = RegistryDBService.getDbWebClient(dbServiceUrl).get()
            .uri("/user/getAllInactiveUsers?date={dateTime}", dateTime).retrieve()
            .bodyToFlux(User.class).map(UserDto::of);
    return userDto;
}

Repository:

@Query("SELECT u from User u  where u.validLoginDate < ?1 AND u.invalidLoginDate < ?1 and u.status!='LOCKED'")
List<User> getAllInactiveUsers(Date dateTime);

Cheers!!

Another approach using Array.prototype.map() and Array.prototype.filter():

var indices = array.map((e, i) => e === value ? i : '').filter(String)

#include <ctime>

void f() {
  using namespace std;
  clock_t begin = clock();

  code_to_time();

  clock_t end = clock();
  double elapsed_secs = double(end - begin) / CLOCKS_PER_SEC;
}

The time() function is only accurate to within a second, but there are CLOCKS_PER_SEC "clocks" within a second. This is an easy, portable measurement, even though it's over-simplified.

All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)

Based on this related answer, you are looking at a list that looks like: A-Z, a-z, 0-9, -, ., _, ~, :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, %, and =. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. % can only be used in conjunction with url encoding as in %20), the RFC has all of these specifics.

If your image is stored in a ResourceDictionary, you can do it with only one line of code:

MyImage.Source = MyImage.FindResource("MyImageKeyDictionary") as ImageSource;

I often ended up doing things like this. Therefore I tried to write a simple function that 'snips' out the unwanted elements in an easy way. This turns matlab logic a bit upside down, but looks good:

b = snip(a,'0')

you can find the function file at: http://www.mathworks.co.uk/matlabcentral/fileexchange/41941-snip-m-snip-elements-out-of-vectorsmatrices

It also works with all other 'x', nan or whatever elements.

I am guessing you are using a 32 bit eclipse with 32 bit JVM. It wont allow heapsize above what you have specified.

Using a 64-bit Eclipse with a 64-bit JVM helps you to start up eclipse with much larger memory. (I am starting with -Xms1024m -Xmx4000m)

Try this,

element.style {
    background: rgba(0, 0, 0, 0) url("img/shopping_bgImg.jpg") no-repeat scroll center center / cover;
}

If you are in an async method you can do this and avoid any ambiguity.

async myMethod(promiseOrNot){
  const theValue = await promiseOrNot()
}

If the function returns promise, it will await and return with the resolved value. If the function returns a value, it will be treated as resolved.

If the function does not return a promise today, but tomorrow returns one or is declared async, you will be future-proof.

From the documentation I get the impression that in your example it would be intended to use:

@Range(min= SEQ_MIN_VALUE, max= SEQ_MAX_VALUE)

Checks whether the annotated value lies between (inclusive) the specified minimum and maximum. Supported data types:

BigDecimal, BigInteger, CharSequence, byte, short, int, long and the respective wrappers of the primitive types

Be careful, make sure you understand the IDE you're using! - Because I didn't. I was trying to import xlsxwriter using PyCharm and was returning this error.

Assuming you have already attempted the pip installation (sudo pip install xlsxwriter) via your cmd prompt, try using another IDE e.g. Geany - & import xlsxwriter.

I tried this and Geany was importing the library fine. I opened PyCharm and navigated to 'File>Settings>Project:>Project Interpreter' xlslwriter was listed though intriguingly I couldn't import it! I double clicked xlsxwriter and hit 'install Package'... And thats it! It worked!

Hope this helps...

Packages and stored procedures in Oracle execute by default using the rights of the package/procedure OWNER, not the currently logged on user.

So if you call a package that creates a user for example, its the package owner, not the calling user that needs create user privilege. The caller just needs to have execute permission on the package.

If you would prefer that the package should be run using the calling user's permissions, then when creating the package you need to specify AUTHID CURRENT_USER

Oracle documentation "Invoker Rights vs Definer Rights" has more information http://docs.oracle.com/cd/A97630_01/appdev.920/a96624/08_subs.htm#18575

Hope this helps.

I came across this solution but this does not really fit my need. So I digged a bit in the d3 source code. I personally would recommend to do it like d3.scale does.

So here you scale the domain to the range. The advantage is that you can flip signs to your target range. This is useful since the y axis on a computer screen goes top down so large values have a small y.

public class Rescale {
    private final double range0,range1,domain0,domain1;

    public Rescale(double domain0, double domain1, double range0, double range1) {
        this.range0 = range0;
        this.range1 = range1;
        this.domain0 = domain0;
        this.domain1 = domain1;
    }

    private double interpolate(double x) {
        return range0 * (1 - x) + range1 * x;
    }

    private double uninterpolate(double x) {
        double b = (domain1 - domain0) != 0 ? domain1 - domain0 : 1 / domain1;
        return (x - domain0) / b;
    }

    public double rescale(double x) {
        return interpolate(uninterpolate(x));
    }
}

And here is the test where you can see what I mean

public class RescaleTest {

    @Test
    public void testRescale() {
        Rescale r;
        r = new Rescale(5,7,0,1);
        Assert.assertTrue(r.rescale(5) == 0);
        Assert.assertTrue(r.rescale(6) == 0.5);
        Assert.assertTrue(r.rescale(7) == 1);

        r = new Rescale(5,7,1,0);
        Assert.assertTrue(r.rescale(5) == 1);
        Assert.assertTrue(r.rescale(6) == 0.5);
        Assert.assertTrue(r.rescale(7) == 0);

        r = new Rescale(-3,3,0,1);
        Assert.assertTrue(r.rescale(-3) == 0);
        Assert.assertTrue(r.rescale(0) == 0.5);
        Assert.assertTrue(r.rescale(3) == 1);

        r = new Rescale(-3,3,-1,1);
        Assert.assertTrue(r.rescale(-3) == -1);
        Assert.assertTrue(r.rescale(0) == 0);
        Assert.assertTrue(r.rescale(3) == 1);
    }
}

Note: For (PHP 7 >= 7.3.0) we can use array_key_last — Gets the last key of an array

array_key_last ( array $array ) : mixed

Many recommend that increasing recursion limit is a good solution however it is not because there will be always limit. Instead use an iterative solution.

def fib(n):
    a,b = 1,1
    for i in range(n-1):
        a,b = b,a+b
    return a
print fib(5)

I would not use .at for performance reasons.

Define a struct:

//#pragma pack(push, 2) //not useful (see comments below)
struct RGB {
    uchar blue;
    uchar green;
    uchar red;  };

And then use it like this on your cv::Mat image:

RGB& rgb = image.ptr<RGB>(y)[x];

image.ptr(y) gives you a pointer to the scanline y. And iterate through the pixels with loops of x and y

Here is what you can do: http://jsfiddle.net/n7cyE/4/

$('#here_table').append('<table></table>');
var table = $('#here_table').children();
 for(i=0;i<3;i++){
    table.append( '<tr><td>' + 'result' +  i + '</td></tr>' );
}

Best regards!

The code is valid (i.e, will compile and execute) in both cases.

One of my lecturers at Uni told us that it is not desirable to have continue, return statements in any loop - for or while. The reason for this is that when examining the code, it is not not immediately clear whether the full length of the loop will be executed or the return or continue will take effect.

See Why is continue inside a loop a bad idea? for an example.

The key point to keep in mind is that for simple scenarios like this it doesn't (IMO) matter but when you have complex logic determining the return value, the code is 'generally' more readable if you have a single return statement instead of several.

With regards to the Garbage Collection - I have no idea why this would be an issue.

My solution combines the target and before selectors for our CMS. Other techniques don't account for text in the anchor. Adjust the height and the negative margin to the offset you need...

:target::before {
    content: '';
    display: block;
    height:      180px;
    margin-top: -180px;
}

their is no need to create asset directory and under it images directory and then you put image. Better is to just create Images directory inside your project where pubspec.yaml exist and put images inside it and access that images just like as shown in tutorial/documention

Do you need to post the the form to an URL or do you only need to detect the submit-event? Because you can detect the submit-event by adding onsubmit="javascript:alert('I do also submit');"

<form action="javascript:alert('submitted');" method="post" id="testForm" onsubmit="javascript:alert('I do also submit');">...</form>

Not sure that this is what you are looking for though.

You are creating a set via set(...) call, and set needs hashable items. You can't have set of lists. Because list's arent hashable.

[[(a,b) for a in range(3)] for b in range(3)] is a list. It's not a hashable type. The __hash__ you saw in dir(...) isn't a method, it's just None.

A list comprehension returns a list, you don't need to explicitly use list there, just use:

>>> [[(a,b) for a in range(3)] for b in range(3)]
[[(0, 0), (1, 0), (2, 0)], [(0, 1), (1, 1), (2, 1)], [(0, 2), (1, 2), (2, 2)]]

Try those:

>>> a = {1, 2, 3}
>>> b= [1, 2, 3]
>>> type(a)
<class 'set'>
>>> type(b)
<class 'list'>
>>> {1, 2, []}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'
>>> print([].__hash__)
None
>>> [[],[],[]] #list of lists
[[], [], []]
>>> {[], [], []} #set of lists

this will help you but this javascript is may not work in all browsers

If you don't mind using an external library, Lodash has lots of wonderful utilities

var people = [
  {
     "f_name":"john",
     "l_name":"doe",
     "sequence":"0",
     "title":"president",
     "url":"google.com",
     "color":"333333"
  },
  {
     "f_name":"michael",
     "l_name":"goodyear",
     "sequence":"0",
     "title":"general manager",
     "url":"google.com",
     "color":"333333"
  }
];


var sorted = _.sortBy(people, "l_name")

You can also sort by multiple properties. Here's a plunk showing it in action

Another variation, i guess :P

python3 -c 'print(__import__("tensorflow").__version__)'

If you need cryptographically-secure random numbers (e.g. for encryption), and you're in a browser, you can use the DOM cryptography API:

int random() {
  final ary = new Int32Array(1);
  window.crypto.getRandomValues(ary);
  return ary[0];
}

This works in Dartium, Chrome, and Firefox, but likely not in other browsers as this is an experimental API.

If you have regular arrays and nothing fancy, this will do. Remember, using array_splice() for inserting elements really means insert before the start index. Be careful when moving elements, because moving up means $targetIndex -1, where as moving down means $targetIndex + 1.

class someArrayClass
{
    private const KEEP_EXISTING_ELEMENTS = 0;

    public function insertAfter(array $array, int $startIndex, $newElements)
    {
        return $this->insertBefore($array, $startIndex + 1, $newElements);
    }

    public function insertBefore(array $array, int $startIndex, $newElements)
    {
        return array_splice($array, $startIndex, self::KEEP_EXISTING_ELEMENTS, $newElements);
    }
}

When I ran taskkill to stop the javaw.exe process it would say it had terminated but remained running. The jqs process (java qucikstart) needs to be stopped also. Running this batch file took care of the issue.

taskkill /f /im jqs.exe
taskkill /f /im javaw.exe
taskkill /f /im java.exe

How about writing some color-based class in a global sass file, thus we don't need to care where variables are. Just like the following:

// base.scss 
@import "./_variables.scss";

.background-color{
    background: $bg-color;
}

and then, we can use the background-color class in any file. My point is that I don't need to import variable.scss in any file, just use it.

If you also have jQuery UI, you can add this:

$(document).ready(function () {
  $(document).tooltip();
});

You then need a title instead of a hidden input. RGraham already posted an answer doing this for you :P

Just to add my own opinion, in case it might be useful to someone. This is what I used.

<div th:class="${request.read ? 'mdl-color-text--grey-800 w500' : ''}"> </div>

If you can look ahead but back, you could reverse the string first and then do a lookahead. Some more work will need to be done, of course.

(Update) V5.1 & Hooks (Requires React >= 16.8)

You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .

const Child = () => {
  const location = useLocation();
  const history = useHistory();
  const match = useRouteMatch("write-the-url-you-want-to-match-here");

  return (
    <div>{location.pathname}</div>
  )
}

export default Child

(Update) V4 & V5

You can use withRouter HOC in order to inject match, history and location in your component props.

class Child extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

(Update) V3

You can use withRouter HOC in order to inject router, params, location, routes in your component props.

class Child extends React.Component {

  render() {
    const { router, params, location, routes } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

Original answer

If you don't want to use the props, you can use the context as described in React Router documentation

First, you have to set up your childContextTypes and getChildContext

class App extends React.Component{

  getChildContext() {
    return {
      location: this.props.location
    }
  }

  render() {
    return <Child/>;
  }
}

App.childContextTypes = {
    location: React.PropTypes.object
}

Then, you will be able to access to the location object in your child components using the context like this

class Child extends React.Component{

   render() {
     return (
       <div>{this.context.location.pathname}</div>
     )
   }

}

Child.contextTypes = {
    location: React.PropTypes.object
 }

This did the trick for me:

{word-break: break-all; }

Use the length property of the [String] type:

if ($dbUserName.length -gt 8) {
    Write-Output "Please enter more than 8 characters."
    $dbUserName = Read-Host "Re-enter database username"
}

Please note that you have to use -gt instead of > in your if condition. PowerShell uses the following comparison operators to compare values and test conditions:

• -eq = equals
• -ne = not equals
• -lt = less than
• -gt = greater than
• -le = less than or equals
• -ge = greater than or equals

In [5]: set(df.Col1).union(set(df.Col2))
Out[5]: {'Bill', 'Bob', 'Joe', 'Mary', 'Steve'}

Or:

set(df.Col1) | set(df.Col2)

something like this:

  public int PowerRating
    {
       get { return base.PowerRating; } // if power inherits from meter...
    }

You can do it server-side with nodejs.

Check out the popular Nodemailer package. There are plenty of transports and plugins for integrating with services like AWS SES and SendGrid!

The following example uses SES transport (Amazon SES):

let nodemailer = require("nodemailer");
let aws = require("aws-sdk");
let transporter = nodemailer.createTransport({
  SES: new aws.SES({ apiVersion: "2010-12-01" })
});

Or you could do this from NuGet Package Manager Console

 Install-Package Microsoft.AspNet.WebApi -Version 5.0.0

And then you will be able to add the reference to System.Web.Http.WebHost 5.0

Use:

docker attach <container name/id here>

The other way, albeit there is a danger to it, is to use attach, but if you Ctrl + C to exit the session, you will also stop the container. If you just want to see what is happening, use docker logs -f.

:~$ docker attach --help
Usage:  docker attach [OPTIONS] CONTAINER

Attach to a running container

Options:
      --detach-keys string   Override the key sequence for detaching a container
      --help                 Print usage
      --no-stdin             Do not attach STDIN
      --sig-proxy            Proxy all received signals to the process (default true)

In [6]: os.listdir?

Type:       builtin_function_or_method
String Form:<built-in function listdir>
Docstring:
listdir(path) -> list_of_strings
Return a list containing the names of the entries in the directory.
path: path of directory to list
The list is in **arbitrary order**.  It does not include the special
entries '.' and '..' even if they are present in the directory.

I know this is not an answer, but I'd like to contribute to this matter for what it's worth. It would be great if they could release justify-self for flexbox to make it truly flexible.

It's my belief that when there are multiple items on the axis, the most logical way for justify-self to behave is to align itself to its nearest neighbours (or edge) as demonstrated below.

I truly hope, W3C takes notice of this and will at least consider it. =)

This way you can have an item that is truly centered regardless of the size of the left and right box. When one of the boxes reaches the point of the center box it will simply push it until there is no more space to distribute.

The ease of making awesome layouts are endless, take a look at this "complex" example.

To determine if a String contains an upper case and a lower case char, you can use the following:

boolean hasUppercase = !password.equals(password.toLowerCase());
boolean hasLowercase = !password.equals(password.toUpperCase());

This allows you to check:

if(!hasUppercase)System.out.println("Must have an uppercase Character");
if(!hasLowercase)System.out.println("Must have a lowercase Character");

Essentially, this works by checking if the String is equal to its entirely lowercase, or uppercase equivalent. If this is not true, then there must be at least one character that is uppercase or lowercase.

As for your other conditions, these can be satisfied in a similar way:

boolean isAtLeast8   = password.length() >= 8;//Checks for at least 8 characters
boolean hasSpecial   = !password.matches("[A-Za-z0-9 ]*");//Checks at least one char is not alpha numeric
boolean noConditions = !(password.contains("AND") || password.contains("NOT"));//Check that it doesn't contain AND or NOT

With suitable error messages as above.

Once you've created the frame the part of the code with your conditional isn't going to get entered. To put it another way, at the time you execute the test if (btn1Clicked == true) , the button has not only not been clicked yet, it hasn't even been displayed to the user.

Lose the booleans and move the line with the btnConvertDocuments.setEnabled(false) into your actionListener. Make the buttons instance variables, do not make them static variables. (Alternatively you could keep the buttons as local variables and assign each of them their own anonymous inner class listener.)

EDIT: CodePen example

For AngularJS, I defined the following directive:

module.directive('isolateScrolling', function () {
  return {
    restrict: 'A',
      link: function (scope, element, attr) {
        element.bind('DOMMouseScroll', function (e) {
          if (e.detail > 0 && this.clientHeight + this.scrollTop == this.scrollHeight) {
            this.scrollTop = this.scrollHeight - this.clientHeight;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
          else if (e.detail < 0 && this.scrollTop <= 0) {
            this.scrollTop = 0;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
        });
        element.bind('mousewheel', function (e) {
          if (e.deltaY > 0 && this.clientHeight + this.scrollTop >= this.scrollHeight) {
            this.scrollTop = this.scrollHeight - this.clientHeight;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
          else if (e.deltaY < 0 && this.scrollTop <= 0) {
            this.scrollTop = 0;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }

          return true;
        });
      }
  };
});

And then added it to the scrollable element (the dropdown-menu ul):

<div class="dropdown">
  <button type="button" class="btn dropdown-toggle">Rename <span class="caret"></span></button>
  <ul class="dropdown-menu" isolate-scrolling>
    <li ng-repeat="s in savedSettings | objectToArray | orderBy:'name' track by s.name">
      <a ng-click="renameSettings(s.name)">{{s.name}}</a>
    </li>
  </ul>
</div>

Tested on Chrome and Firefox. Chrome's smooth scrolling defeats this hack when a large mousewheel movement is made near (but not at) the top or bottom of the scroll region.

function slugify(text){
  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(/[^\u0100-\uFFFF\w\-]/g,'-') // Remove all non-word chars ( fix for UTF-8 chars )
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '');            // Trim - from end of text
}

*based on https://gist.github.com/mathewbyrne/1280286

now you can transform this string:

Barack_Obama       ?????_????? ~!@#$%^&*()+/-+?><:";'{}[]\|`

into:

barack_obama-?????_?????

applying to your code:

$("#Restaurant_Name").keyup(function(){
    var Text = $(this).val();
    Text = slugify(Text);
    $("#Restaurant_Slug").val(Text);
});

Each controller has it's own scope(s) so that's causing your issue.

Having two controllers that want access to the same data is a classic sign that you want a service. The angular team recommends thin controllers that are just glue between views and services. And specifically- "services should hold shared state across controllers".

Happily, there's a nice 15-minute video describing exactly this (controller communication via services): video

One of the original author's of Angular, Misko Hevery, discusses this recommendation (of using services in this situation) in his talk entitled Angular Best Practices (skip to 28:08 for this topic, although I very highly recommended watching the whole talk).

You can use events, but they are designed just for communication between two parties that want to be decoupled. In the above video, Misko notes how they can make your app more fragile. "Most of the time injecting services and doing direct communication is preferred and more robust". (Check out the above link starting at 53:37 to hear him talk about this)

When an element, such as a div is floated, its parent container no longer considers its height, i.e.

<div id="main">
  <div id="child" style="float:left;height:40px;"> Hi</div>
</div>

The parent container will not be be 40 pixels tall by default. This causes a lot of weird little quirks if you're using these containers to structure layout.

So the clearfix class that various frameworks use fixes this problem by making the parent container "acknowledge" the contained elements.

Day to day, I normally just use frameworks such as 960gs, Twitter Bootstrap for laying out and not bothering with the exact mechanics.

Despite the danger of stating the obvious: With a unit test you want to test the correct behaviour of the object - and this is defined in terms of its public interface. You are not interested in how the object accomplishes this task - this is an implementation detail and not visible to the outside. This is one of the things why OO was invented: That implementation details are hidden. So there is no point in testing private members. You said you need 100% coverage. If there is a piece of code that cannot be tested by using the public interface of the object, then this piece of code is actually never called and hence not testable. Remove it.

In cases where the private method is not void and the return value is used as a parameter to an external dependency's method, you can mock the dependency and use an ArgumentCaptor to capture the return value. For example:

ArgumentCaptor<ByteArrayOutputStream> csvOutputCaptor = ArgumentCaptor.forClass(ByteArrayOutputStream.class);
//Do your thing..
verify(this.awsService).uploadFile(csvOutputCaptor.capture());
....
assertEquals(csvOutputCaptor.getValue().toString(), "blabla");

You can easily create a function to do that for you, change the length or even add it to native Array as remove() function for reuse.

Imagine you have this array:

var arr = [1, 2, 3, 4, 5]; //the array

OK, just simply run this:

arr.length = 0; //change the length

and the result is:

[] //result

easy way to empty an array...

Also using loop which is not necessary but just another way to do that:

/* could be arr.pop() or arr.splice(0)
don't need to return as main array get changed */

function remove(arr) {
  while(arr.length) {
    arr.shift(); 
  }
}

There are also tricky way which you can think about, for example something like this:

arr.splice(0, arr.length); //[]

So if arr has 5 items, it will splice 5 items from 0, which means nothing will remain in the array.

Also other ways like simply reassign the array for example:

arr = []; //[]

If you look at the Array functions, there are many other ways to do this, but the most recommended one could be changing the length.

As I said in the first place, you can also prototype remove() as it's the answer to your question. you can simply choose one of the methods above and prototype it to Array object in JavaScript, something like:

Array.prototype.remove = Array.prototype.remove || function() {
  this.splice(0, this.length);
};

and you can simply call it like this to empty any array in your javascript application:

arr.remove(); //[]

In C# you cannot define true global variables (in the sense that they don't belong to any class).

This being said, the simplest approach that I know to mimic this feature consists in using a static class, as follows:

public static class Globals
{
    public const Int32 BUFFER_SIZE = 512; // Unmodifiable
    public static String FILE_NAME = "Output.txt"; // Modifiable
    public static readonly String CODE_PREFIX = "US-"; // Unmodifiable
}

You can then retrieve the defined values anywhere in your code (provided it's part of the same namespace):

String code = Globals.CODE_PREFIX + value.ToString();

In order to deal with different namespaces, you can either:

• declare the Globals class without including it into a specific namespace (so that it will be placed in the global application namespace);
• insert the proper using directive for retrieving the variables from another namespace.

Try this, a simpler solution.

byte[] salt = "ThisIsASecretKey".getBytes();
Key key = new SecretKeySpec(salt, 0, 16, "AES");

Cipher cipher = Cipher.getInstance("AES");

You have writer.close(); in your code. So bash receives EOF on its stdin and exits. Then you get Broken pipe when trying to read from the stdoutof the defunct bash.

Download the Linux SDK from the Android website. Copy the folder to whereever you want to extract the contents. Open a terminal there, and then run:

sudo apt-get install unzip
sudo tar xvzf android-studio-ide-135.1641136-linux.zip
cd android-studio-ide-135.1641136-linux
./studio.sh

JDK 1.7 is required for Studio 1.0 onwards:

1. Download the ubuntu zip from the d.android.com and repeat the steps from above

2. Download the jdk 1.7 by executing the following commands in terminal as mentioned webupd8:
   
   

   sudo add-apt-repository ppa:webupd8team/java
   sudo apt-get update
   sudo apt-get install oracle-java7-installer
   

3. Open Android Studio and install the SDK tools.

Caveats:

1. If your system has a 32 bit processor, use Platform Tools r23.0.1. Refer to this bug for details.

Note: If you are running a 64-bit version of Ubuntu, you need to install some 32-bit libraries with the following command:

$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1

Your Money class could be represented as a subclass of Long or having a member representing the money value as a native long. Then when assigning values to your money instantiations, you will always be storing values that are actually REAL money values. You simply output your Money object (via your Money's overridden toString() method) with the appropriate formatting. e.g $1.25 in a Money object's internal representation is 125. You represent the money as cents, or pence or whatever the minimum denomination in the currency you are sealing with is ... then format it on output. No you can NEVER store an 'illegal' money value, like say $1.257.

My solution to this error was to update the typescript version with this command:

npm install -g typescript@latest as I was using Windows. However on Mac this can also be doable by sudo npm install -g typescript@latest

The general approach is to convert the data to long format (using melt() from package reshape or reshape2) or gather()/pivot_longer() from the tidyr package:

library("reshape2")
library("ggplot2")

test_data_long <- melt(test_data, id="date")  # convert to long format

ggplot(data=test_data_long,
       aes(x=date, y=value, colour=variable)) +
       geom_line()

Also see this question on reshaping data from wide to long.

Before writing this off as impossible I suggest you look at the source code of the lsof command.

There may be restrictions but lsof seems capable of determining the file descriptor and file name. This information exists in the /proc filesystem so it should be possible to get at from your program.

Write the process as a server-side script in whatever language (php/bash/perl/etc) is handy and then call it from the process control functions in your php script.

The function probably detects if standard io is used as the output stream and if it is then that will set the return value..if not then it ends

proc_close( proc_open( "./command --foo=1 &", array(), $foo ) );

I tested this quickly from the command line using "sleep 25s" as the command and it worked like a charm.

1. From your IDE, create a remote debug configuration, configure it for the default JPDA Tomcat port which is port 8000.

2. From the command line:

   Linux:

   cd apache-tomcat/bin
   export JPDA_SUSPEND=y
   ./catalina.sh jpda run
   

   Windows:

   cd apache-tomcat\bin
   set JPDA_SUSPEND=y
   catalina.bat jpda run
   

3. Execute the remote debug configuration from your IDE, and Tomcat will start running and you are now able to set breakpoints in the IDE.

Note:

The JPDA_SUSPEND=y line is optional, it is useful if you want that Apache Tomcat doesn't start its execution until step 3 is completed, useful if you want to troubleshoot application initialization issues.

I had the same error show up while creating the project but I wasn't behind a proxy and hence the above solutions did not work for me.

I found this forum. It suggested to:

1. Delete or Rename .m2 directory from your HOME directory

In Windows - C:\Users\<username>\Windows

OR

In Linux - /home/<username>

2. restart the Eclipse / STS spring tool suite (which am using)

It worked!

Use the below code

Character.isLetterOrDigit(string.charAt(index))

Here is the BSD implementation:

int
strcmp(s1, s2)
    register const char *s1, *s2;
{
    while (*s1 == *s2++)
        if (*s1++ == 0)
            return (0);
    return (*(const unsigned char *)s1 - *(const unsigned char *)(s2 - 1));
}

Once there is a mismatch between two characters, it just returns the difference between those two characters.

In Winform App(C#):

static string strFilesLoc = Path.GetFullPath(Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), @"..\..\")) + "Resources\\";
    public static string[] GetFontFamily()
            {
                var result = File.ReadAllText(strFilesLoc + "FontFamily.txt").Trim();
                string[] items = result.Split(new char[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
                return items;
            }

In-text file(FontFamily.txt):
Microsoft Sans Serif

true

If the array contains integers, the value cannot be NULL. NULL can be used if the array contains pointers.

SomeClass* myArray[2];
myArray[0] = new SomeClass();
myArray[1] = NULL;

if (myArray[0] != NULL) { // this will be executed }
if (myArray[1] != NULL) { // this will NOT be executed }

As http://en.cppreference.com/w/cpp/types/NULL states, NULL is a null pointer constant!

The easiest way to send (simulate) KeyStrokes to any window is to use the SendKeys.Send method of .NET Framework.

Checkout this very intuitive MSDN article http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx

Particularly for your case, if your browser window is in focus, sending F5 would just involve the following line of code:

SendKeys.Send("{F5}");

Here is a extension method, this allows coding like the SQL IN command.

public static bool In<T>(this T o, params T[] values)
{
    if (values == null) return false;

    return values.Contains(o);
}
public static bool In<T>(this T o, IEnumerable<T> values)
{
    if (values == null) return false;

    return values.Contains(o);
}

This allows stuff like that:

List<int> ints = new List<int>( new[] {1,5,7});
int i = 5;
bool isIn = i.In(ints);

Or:

int i = 5;
bool isIn = i.In(1,2,3,4,5);

Once you're in the directory, just run it as ./myScript.sh

Just to clarify in complete detail. This is what works with the current version of jQuery Ui

$( "#tabs" ).tabs( "option", "active", # );

where # is the index of the tab you want to make active.

In addition to the existing answer it is possible to set a default option as follows:

echo off
ECHO A current build of Test Harness exists.
set delBuild=n
set /p delBuild=Delete preexisting build [y/n] (default - %delBuild%)?:

This allows users to simply hit "Enter" if they want to enter the default.

In Bluetooth, all objects are identified by UUIDs. These include services, characteristics and many other things. Bluetooth maintains a database of assigned numbers for standard objects, and assigns sub-ranges for vendors (that have paid enough for a reservation). You can view this list here:

https://www.bluetooth.com/specifications/assigned-numbers/

If you are implementing a standard service (e.g. a serial port, keyboard, headset, etc.) then you should use that service's standard UUID - that will allow you to be interoperable with devices that you didn't develop.

If you are implementing a custom service, then you should generate unique UUIDs, in order to make sure incompatible third-party devices don't try to use your service thinking it is something else. The easiest way is to generate random ones and then hard-code the result in your application (and use the same UUIDs in the devices that will connect to your service, of course).

No need to us javascript. Boostrap modal adds .in class when it appears. Just modify this class combination with modalclassName.fade.in with flex css and you are done.

add this css to center your modal vertically and horizontally.

.modal.fade.in {
    display: flex !important;
    justify-content: center;
    align-items: center;
}
.modal.fade.in .modal-dialog {
    width: 100%;
}

You can make function getStyles that'll take an element and other arguments are properties that's values you want.

const convertRestArgsIntoStylesArr = ([...args]) => {
    return args.slice(1);
}

const getStyles = function () {
    const args = [...arguments];
    const [element] = args;

    let stylesProps = [...args][1] instanceof Array ? args[1] : convertRestArgsIntoStylesArr(args);

    const styles = window.getComputedStyle(element);
    const stylesObj = stylesProps.reduce((acc, v) => {
        acc[v] = styles.getPropertyValue(v);
        return acc;
    }, {});

    return stylesObj;
};

Now, you can use this function like this:

const styles = getStyles(document.body, "height", "width");

OR

const styles = getStyles(document.body, ["height", "width"]);

You can use a function comparator without wrapping it like so:

bool comparator(const MyType &lhs, const MyType &rhs)
{
    return [...];
}

std::set<MyType, bool(*)(const MyType&, const MyType&)> mySet(&comparator);

which is irritating to type out every time you need a set of that type, and can cause issues if you don't create all sets with the same comparator.

User order by with that field, and then do distinct.

ProductOrder.objects.order_by('category').values_list('category', flat=True).distinct()

This is another option to write a pandas dataframe directly into a matplotlib table:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots()

# hide axes
fig.patch.set_visible(False)
ax.axis('off')
ax.axis('tight')

df = pd.DataFrame(np.random.randn(10, 4), columns=list('ABCD'))

ax.table(cellText=df.values, colLabels=df.columns, loc='center')

fig.tight_layout()

plt.show()

Try this:

 Select 
    Id, 
    Salt, 
    Password, 
    BannedEndDate, 
    (Select Count(*) 
        From LoginFails 
        Where username = '" + LoginModel.Username + "' And IP = '" + Request.ServerVariables["REMOTE_ADDR"] + "')
 From Users 
 Where username = '" + LoginModel.Username + "'

And I recommend you strongly to use parameters in your query to avoid security risks with sql injection attacks!

Hope that helps!

I solved this on 12.10 by installing libssl-dev.

sudo apt-get install libssl-dev

I think you have to be sure what type of installation you have binary or source. To check what binary packages is installed: with root rights execute following command:

dpkg -l |grep apache2

result should be something like:

dpkg -l |grep apache2

ii  apache2                               2.4.10-10+deb8u8                      amd64        Apache HTTP Server
ii  apache2-bin                           2.4.10-10+deb8u8                      amd64        Apache HTTP Server (modules and other binary files)
ii  apache2-data                          2.4.10-10+deb8u8                      all          Apache HTTP Server (common files)
ii  apache2-doc                           2.4.10-10+deb8u8                      all          Apache HTTP Server (on-site documentation)

To find version you can run :

apache2ctl -V |grep -i "Server version"

result should be something like: Server version: Apache/2.4.10 (Debian)

You can use shuf. On some systems at least (doesn't appear to be in POSIX).

As jleedev pointed out: sort -R might also be an option. On some systems at least; well, you get the picture. It has been pointed out that sort -R doesn't really shuffle but instead sort items according to their hash value.

^{[Editor's note: sort -R almost shuffles, except that duplicate lines / sort keys always end up next to each other. In other words: only with unique input lines / keys is it a true shuffle. While it's true that the output order is determined by hash values, the randomness comes from choosing a random hash function - see manual.]}

TL;DR: sleep infinity actually sleeps the maximum time allowed, which is finite.

Wondering why this is not documented anywhere, I bothered to read the sources from GNU coreutils and I found it executes roughly what follows:

1. Use strtod from C stdlib on the first argument to convert 'infinity' to a double precision value. So, assuming IEEE 754 double precision the 64-bit positive infinity value is stored in the seconds variable.
2. Invoke xnanosleep(seconds) (found in gnulib), this in turn invokes dtotimespec(seconds) (also in gnulib) to convert from double to struct timespec.
3. struct timespec is just a pair of numbers: integer part (in seconds) and fractional part (in nanoseconds). Naïvely converting positive infinity to integer would result in undefined behaviour (see §6.3.1.4 from C standard), so instead it truncates to TYPE_MAXIMUM(time_t).
4. The actual value of TYPE_MAXIMUM(time_t) is not set in the standard (even sizeof(time_t) isn't); so, for the sake of example let's pick x86-64 from a recent Linux kernel.

This is TIME_T_MAX in the Linux kernel, which is defined (time.h) as:

(time_t)((1UL << ((sizeof(time_t) << 3) - 1)) - 1)

Note that time_t is __kernel_time_t and time_t is long; the LP64 data model is used, so sizeof(long) is 8 (64 bits).

Which results in: TIME_T_MAX = 9223372036854775807.

That is: sleep infinite results in an actual sleep time of 9223372036854775807 seconds (10^11 years). And for 32-bit linux systems (sizeof(long) is 4 (32 bits)): 2147483647 seconds (68 years; see also year 2038 problem).

Edit: apparently the nanoseconds function called is not directly the syscall, but an OS-dependent wrapper (also defined in gnulib).

There's an extra step as a result: for some systems where HAVE_BUG_BIG_NANOSLEEP is true the sleep is truncated to 24 days and then called in a loop. This is the case for some (or all?) Linux distros. Note that this wrapper may be not used if a configure-time test succeeds (source).

In particular, that would be 24 * 24 * 60 * 60 = 2073600 seconds (plus 999999999 nanoseconds); but this is called in a loop in order to respect the specified total sleep time. Therefore the previous conclusions remain valid.

In conclusion, the resulting sleep time is not infinite but high enough for all practical purposes, even if the resulting actual time lapse is not portable; that depends on the OS and architecture.

To answer the original question, this is obviously good enough but if for some reason (a very resource-constrained system) you really want to avoid an useless extra countdown timer, I guess the most correct alternative is to use the cat method described in other answers.

Edit: recent GNU coreutils versions will try to use the pause syscall (if available) instead of looping. The previous argument is no longer valid when targeting these newer versions in Linux (and possibly BSD).

Portability

This is an important valid concern:

• sleep infinity is a GNU coreutils extension not contemplated in POSIX. GNU's implementation also supports a "fancy" syntax for time durations, like sleep 1h 5.2s while POSIX only allows a positive integer (e.g. sleep 0.5 is not allowed).
• Some compatible implementations: GNU coreutils, FreeBSD (at least from version 8.2?), Busybox (requires to be compiled with options FANCY_SLEEP and FLOAT_DURATION).
• The strtod behaviour is C and POSIX compatible (i.e. strtod("infinity", 0) is always valid in C99-conformant implementations, see §7.20.1.3).

format: "YYYY" 

Should be capital instead of "yyyy"

Here are the ways to assign parent object in child object of Bi-directional relations ?

Suppose you have a relation say One-To-Many,then for each parent object,a set of child object exists. In bi-directional relations,each child object will have reference to its parent.

eg : Each Department will have list of Employees and each Employee is part of some department.This is called Bi directional relations.

To achieve this, one way is to assign parent in child object while persisting parent object

Parent parent = new Parent();
...
Child c1 = new Child();
...
c1.setParent(parent);

List<Child> children = new ArrayList<Child>();
children.add(c1);
parent.setChilds(children);

session.save(parent);

Other way is, you can do using hibernate Intercepter,this way helps you not to write above code for all models.

Hibernate interceptor provide apis to do your own work before perform any DB operation.Likewise onSave of object, we can assign parent object in child objects using reflection.

public class CustomEntityInterceptor extends EmptyInterceptor {

    @Override
    public boolean onSave(
            final Object entity, final Serializable id, final Object[] state, final String[] propertyNames,
            final Type[] types) {
        if (types != null) {
            for (int i = 0; i < types.length; i++) {
                if (types[i].isCollectionType()) {
                    String propertyName = propertyNames[i];
                    propertyName = propertyName.substring(0, 1).toUpperCase() + propertyName.substring(1);
                    try {
                        Method method = entity.getClass().getMethod("get" + propertyName);
                        List<Object> objectList = (List<Object>) method.invoke(entity);

                        if (objectList != null) {
                            for (Object object : objectList) {
                                String entityName = entity.getClass().getSimpleName();
                                Method eachMethod = object.getClass().getMethod("set" + entityName, entity.getClass());
                                eachMethod.invoke(object, entity);
                            }
                        }

                    } catch (NoSuchMethodException | InvocationTargetException | IllegalAccessException e) {
                        throw new RuntimeException(e);
                    }
                }
            }
        }
        return true;
    }

}

And you can register Intercepter to configuration as

new Configuration().setInterceptor( new CustomEntityInterceptor() );

If you want to get stored procedures using specific column only, you can use try this query:

SELECT DISTINCT Name
FROM sys.Procedures
WHERE object_definition(OBJECT_ID) LIKE '%CreatedDate%';

If you want to get stored procedures using specific column of table, you can use below query :

SELECT DISTINCT Name 
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%';

After converting your varchar2 date to a true date datatype, then convert back to varchar2 with the desired mask:

to_char(to_date('01/02/2012','MM/DD/YYYY'),'WW')

If you want the week number in a number datatype, you can wrap the statement in to_number():

to_number(to_char(to_date('01/02/2012','MM/DD/YYYY'),'WW'))

However, you have several week number options to consider:

WW  Week of year (1-53) where week 1 starts on the first day of the year and continues to the seventh day of the year.
W   Week of month (1-5) where week 1 starts on the first day of the month and ends on the seventh.
IW  Week of year (1-52 or 1-53) based on the ISO standard.

There are many ways to perform your task, but the most elegant are, I believe, using css. Here are basic steps

1. Listening option selection event, biding adding/removing some class to container action, which contains all divs you are interested in (for example, body)
2. Adding styles for hiding all divs except one.
3. Well done, sir.

This works pretty well if there a few divs, since more elements you want to toggle, more css rules should be written. Here is more general solution, binding action, base on following steps: 1. find all elements using some selector (usually it looks like '.menu-container .menu-item') 2. find one of found elements, which is current visible, hide it 3. make visible another element, the one you desire to be visible under new circumstances.

javascript it a rather timtoady language )

Though this post has been here for quite a while, the solutions are not pure JS. Though Jason noted that requesting permissions is not ideal, I consider it a good thing since the user can reject it explicitly. I still post this code, though (almost) the same thing can also be seen in another post by ifaour. Consider this the JS only version without too much attention to detail.

The basic code is rather simple:

FB.api("me/likes/SOME_ID", function(response) {
    if ( response.data.length === 1 ) { //there should only be a single value inside "data"
        console.log('You like it');
    } else {
        console.log("You don't like it");
    }
});

ALternatively, replace me with the proper UserID of someone else (you might need to alter the permissions below to do this, like friends_likes) As noted, you need more than the basic permission:

FB.login(function(response) {
    //do whatever you need to do after a (un)successfull login         
}, { scope: 'user_likes' });

In short, yes. But there are times when you might favor one vs. the other. Google "case switch vs. if else". There are some discussions already on SO too. Also, here is a good video that talks about it in the context of MATLAB:

http://blogs.mathworks.com/pick/2008/01/02/matlab-basics-switch-case-vs-if-elseif/

Personally, when I have 3 or more cases, I usually just go with case/switch.

One of the elements to consider as you design your interface is on what event (when A takes place, B happens...) does the new checkbox end up being added?

Let's say there is a button next to the text box. When the button is clicked the value of the textbox is turned into a new checkbox. Our markup could resemble the following...

<div id="checkboxes">
    <input type="checkbox" /> Some label<br />
    <input type="checkbox" /> Some other label<br />
</div>

<input type="text" id="newCheckText" /> <button id="addCheckbox">Add Checkbox</button>

Based on this markup your jquery could bind to the click event of the button and manipulate the DOM.

$('#addCheckbox').click(function() {
    var text = $('#newCheckText').val();
    $('#checkboxes').append('<input type="checkbox" /> ' + text + '<br />');
});

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You can read the full documentation here.

Just remove COLUMN from ADD COLUMN

ALTER TABLE Employees
  ADD EmployeeID numeric NOT NULL IDENTITY (1, 1)

ALTER TABLE Employees ADD CONSTRAINT
        PK_Employees PRIMARY KEY CLUSTERED 
        (
          EmployeeID
        ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, 
        ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

You can always use the stl:

auto min_value = *std::min_element(v.begin(),v.end());

1. As other stated, it is not needed for C, but for C++.

2. Including the cast may allow a C program or function to compile as C++.

3. In C it is unnecessary, as void * is automatically and safely promoted to any other pointer type.

4. But if you cast then, it can hide an error if you forgot to include stdlib.h. This can cause crashes (or, worse, not cause a crash until way later in some totally different part of the code).

   Because stdlib.h contains the prototype for malloc is found. In the absence of a prototype for malloc, the standard requires that the C compiler assumes malloc returns an int. If there is no cast, a warning is issued when this integer is assigned to the pointer; however, with the cast, this warning is not produced, hiding a bug.

Unfortunately max-width + max-height do not fully cover my task... So I have found another solution:

To save the Image ratio while scaling you also can use object-fit CSS3 propperty.

Useful article: Control image aspect ratios with CSS3

img {
    width: 100%; /* or any custom size */
    height: 100%; 
    object-fit: contain;
}

Bad news: IE not supported (Can I Use)

Thought I would give Sugar.js a mention. It has a truncate method that is pretty smart.

From the documentation:

Truncates a string. Unless split is true, truncate will not split words up, and instead discard the word where the truncation occurred.

Example:

'just sittin on the dock of the bay'.truncate(20)

Output:

just sitting on...

Because of your initialization wrong.

Don't do like this,

MethodName _methodName;

Do like this,

MethodName _methodName = MethodName();

A quick google pointed me to this page. It explains that from sql server 2005 onwards you can set the default schema of a user with the ALTER USER statement. Unfortunately, that means that you change it permanently, so if you need to switch between schemas, you would need to set it every time you execute a stored procedure or a batch of statements. Alternatively, you could use the technique described here.

If you are using sql server 2000 or older this page explains that users and schemas are then equivalent. If you don't prepend your table name with a schema\user, sql server will first look at the tables owned by the current user and then the ones owned by the dbo to resolve the table name. It seems that for all other tables you must prepend the schema\user.

Retrofit 2.0 solution

@Multipart
@POST(APIUtils.UPDATE_PROFILE_IMAGE_URL)
public Call<CommonResponse> requestUpdateImage(@PartMap Map<String, RequestBody> map);

and

    Map<String, RequestBody> params = new HashMap<>();

    params.put("newProfilePicture" + "\"; filename=\"" + FilenameUtils.getName(file.getAbsolutePath()), RequestBody.create(MediaType.parse("image/jpg"), file));



 Call<CommonResponse> call = request.requestUpdateImage(params);

you can use
image/jpg image/png image/gif

Controller code

myApp.controller('mainController', ['$scope', '$log', function($scope, $log) {
    $scope.person = {
        name:"sangeetha PH",
       address:"first Block"
    }
}]);

Directive Code

myApp.directive('searchResult',function(){

Normally, you do something like this:

def myFunction(a,b,c):
   if not isinstance(a, int):
      raise TypeError("Expected int, got %s" % (type(a),))
   if b <= 0 or b >= 10:
      raise ValueError("Value %d out of range" % (b,))
   if not c:
      raise ValueError("String was empty")

   # Rest of function

With Maven you can use this plugin:

If you have global environment variables defined outside Gradle,

test {
    environment "ENV_VAR",  System.getenv('ENV_VAR')
    useJUnitPlatform()
}

I use this to get the height of an element (returns float):

document.getElementById('someDiv').getBoundingClientRect().height

It also works when you use the virtual DOM. I use it in Vue like this:

this.$refs['some-ref'].getBoundingClientRect().height

For a Vue component:

this.$refs['some-ref'].$el.getBoundingClientRect().height

When using Java 7+ use the following method to download a file from the Internet and save it to some directory:

private static Path download(String sourceURL, String targetDirectory) throws IOException

In Firefox, https://bug743252.bugzilla.mozilla.org/attachment.cgi?id=714383 (view page source :: tag HTML).

In your code, replace <html> with <html moznomarginboxes mozdisallowselectionprint>.

In others browsers, I don't know, but you can view http://www.mintprintables.com/print-tips/header-footer-windows/

If your goal is to remove all the options from the select except the first one (typically the 'Please pick an item' option) you could use:

$('#mySelect').find('option:not(:first)').remove();

When working with Angular the recent update to Angular 8 introduced that a static property inside @ViewChild() is required as stated here and here. Then your code would require this small change:

@ViewChild('one') d1:ElementRef;

into

// query results available in ngOnInit
@ViewChild('one', {static: true}) foo: ElementRef;

OR

// query results available in ngAfterViewInit
@ViewChild('one', {static: false}) foo: ElementRef;

All apps will continue to work in the vertically stretched screen from what I could tell in today's presentation. They will be letterboxed or basically the extra 88 points in height would simply be black.

If you only plan to support iOS 6+, then definitely consider using Auto Layout. It removes all fixed layout handling and instead uses constraints to lay things out. Nothing will be hard-coded, and your life will become a lot simpler.

However, if you have to support older iOS's, then it really depends on your application. A majority of applications that use a standard navigation bar, and/or tab bar, could simply expand the content in the middle to use up that extra points. Set the autoresizing mask of the center content to expand in both directions.

view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

It works great out of the box for table views, however, if your app used pixel-perfect layout for displaying content, then your best bet would be to re-imagine the content so that it can accommodate varying heights.

If that's not a possibility, then the only remaining option is to have two UIs (pre iPhone 5, and iPhone 5).

If that sounds ugly, then you could go with the default letterboxed model where the extra points/pixels just show up black.

Edit

To enable your apps to work with iPhone 5, you need to add a retina version of the launcher image. It should be named [email protected]. And it has to be retina quality - there's no backward compatibility here :)

You could also select this image from within Xcode. Go to the target, and under the Summary section, look for Launch Images. The image has to be 640x1136 pixels in size. Here's a screenshot of where to find it, if that helps.
