You need geopy

pip install geopy

and then:

from geopy.geocoders import Nominatim
geolocator = Nominatim()
location = geolocator.reverse("48.8588443, 2.2943506")

print(location.address)

to get more information:

print (location.raw)

In python3.x it can be done using :

# Converting lat/long to cartesian
import numpy as np

def get_cartesian(lat=None,lon=None):
    lat, lon = np.deg2rad(lat), np.deg2rad(lon)
    R = 6371 # radius of the earth
    x = R * np.cos(lat) * np.cos(lon)
    y = R * np.cos(lat) * np.sin(lon)
    z = R *np.sin(lat)
    return x,y,z

SELECT latitude, longitude, SQRT(
    POW(69.1 * (latitude - [startlat]), 2) +
    POW(69.1 * ([startlng] - longitude) * COS(latitude / 57.3), 2)) AS distance
FROM TableName HAVING distance < 25 ORDER BY distance;

where [starlat] and [startlng] is the position where to start measuring the distance.

This is what you need : ternary operator, please take a look at this

here is the code to print only the headers or columns of the csv file.

import csv
HEADERS = next(csv.reader(open('filepath.csv')))
print (HEADERS)

Another method with pandas

import pandas as pd
HEADERS = list(pd.read_csv('filepath.csv').head(0))
print (HEADERS)

I think the $_SERVER superglobal has the information you're looking for. It might be something like this:

echo $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']

You can see the relevant PHP documentation here.

Difference between Paint() and Repaint() method

Paint():

This method holds instructions to paint this component. Actually, in Swing, you should change paintComponent() instead of paint(), as paint calls paintBorder(), paintComponent() and paintChildren(). You shouldn't call this method directly, you should call repaint() instead.

Repaint():

This method can't be overridden. It controls the update() -> paint() cycle. You should call this method to get a component to repaint itself. If you have done anything to change the look of the component, but not its size ( like changing color, animating, etc. ) then call this method.

All other answers show how to calculate the new image height in function of the new image width or vice-versa and how to resize the image using Java Image API. For those people who are looking for a straightforward solution I recommend any java image processing framework that can do this in a single line.

The exemple below uses Marvin Framework:

// 300 is the new width. The height is calculated to maintain aspect.
scale(image.clone(), image, 300);

Necessary import:

import static marvin.MarvinPluginCollection.*

If you are not root user then, use following commands:

There are two ways to do it -

1.

sudo vi path_to_file/file_name

Press Esc and then type below respectively

:wq //save and exit
:q! //exit without saving

2. sudo nano path_to_file/file_name

When using nano: after you finish editing press ctrl+x then it will ask save Y/N.
If you want to save press Y, if not press N. And press enter to exit the editor.

In this example of a rc.local script I use io redirection at the very first line of execution to my own log file:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exec 2> /tmp/rc.local.log  # send stderr from rc.local to a log file
exec 1>&2                      # send stdout to the same log file
set -x                         # tell sh to display commands before execution

/opt/stuff/somefancy.error.script.sh

exit 0

They are signals that application developers use. The kernel shouldn't ever send these to a process. You can send them using kill(2) or using the utility kill(1).

If you intend to use signals for synchronization you might want to check real-time signals (there's more of them, they are queued, their delivery order is guaranteed etc).

This works in IE9 (Compatibility View and Normal Mode), Firefox 17, and Chrome 23:

<table>
    <tr>
        <td style="background-image:url(untitled.png); background-position:right 0px; background-repeat:no-repeat;">
            Hello World
        </td>
    </tr>
</table>

Another way you can achieve the desired effect is to use this Material Search View library. It handles search history automatically and it's possible to provide search suggestions to the view as well.

Sample: (It's shown in Portuguese, but it also works in english and italian).

Setup

Before you can use this lib, you have to implement a class named MsvAuthority inside the br.com.mauker package on your app module, and it should have a public static String variable called CONTENT_AUTHORITY. Give it the value you want and don't forget to add the same name on your manifest file. The lib will use this file to set the Content Provider authority.

Example:

MsvAuthority.java

package br.com.mauker;

public class MsvAuthority {
    public static final String CONTENT_AUTHORITY = "br.com.mauker.materialsearchview.searchhistorydatabase";
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>

    <application ... >
        <provider
        android:name="br.com.mauker.materialsearchview.db.HistoryProvider"
        android:authorities="br.com.mauker.materialsearchview.searchhistorydatabase"
        android:exported="false"
        android:protectionLevel="signature"
        android:syncable="true"/>
    </application>

</manifest>

Usage

To use it, add the dependency:

compile 'br.com.mauker.materialsearchview:materialsearchview:1.2.0'

And then, on your Activity layout file, add the following:

<br.com.mauker.materialsearchview.MaterialSearchView
    android:id="@+id/search_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

After that, you'll just need to get the MaterialSearchView reference by using getViewById(), and open it up or close it using MaterialSearchView#openSearch() and MaterialSearchView#closeSearch().

P.S.: It's possible to open and close the view not only from the Toolbar. You can use the openSearch() method from basically any Button, such as a Floating Action Button.

// Inside onCreate()
MaterialSearchView searchView = (MaterialSearchView) findViewById(R.id.search_view);
Button bt = (Button) findViewById(R.id.button);

bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            searchView.openSearch();
        }
    });

You can also close the view using the back button, doing the following:

@Override
public void onBackPressed() {
    if (searchView.isOpen()) {
        // Close the search on the back button press.
        searchView.closeSearch();
    } else {
        super.onBackPressed();
    }
}

For more information on how to use the lib, check the github page.

Just changed Amber's COUNT(*) to COUNT(1) for the better performance.

SELECT name, COUNT(1) as count 
FROM tablename 
GROUP BY name 
ORDER BY count DESC;

Have you taken a look at Response.js? It's designed for this kind of thing. Combine Response.band and Response.resize.

http://responsejs.com/

Response.resize(function() {
    if ( Response.band(1200) )
    {
       // 1200+
    }    
    else if ( Response.band(992) )
    {
        // 992+
    }
    else if ( Response.band(768) )
    {
        // 768+
    }
    else 
    {
        // 0->768
    }
});

SELECT (SELECT COUNT(*) FROM table1) + (SELECT COUNT(*) FROM table2) FROM dual;

The trick is to use "DateTime" to manipulate dates; only use integers and strings when you need a "final result" from the date.

For example (pseudo code):

1. Get "DateTime tomorrow = Now + 1"

2. Determine date, day of week, day of month - whatever you want - of the resulting date.

In [56]: df = pd.DataFrame(np.abs(randn(3, 4)), index=[1,2,3], columns=['A','B','C','D'])

In [57]: df.divide(df.sum(axis=1), axis=0)
Out[57]: 
          A         B         C         D
1  0.319124  0.296653  0.138206  0.246017
2  0.376994  0.326481  0.230464  0.066062
3  0.036134  0.192954  0.430341  0.340571

d = {0: 'zero', '0': 'ZERO', 1: 'one', '1': 'ONE'}

print("List of enumerated d= ", list(enumerate(d.items())))

output:

List of enumerated d=  [(0, (0, 'zero')), (1, ('0', 'ZERO')), (2, (1, 'one')), (3, ('1', 'ONE'))]

Reloading existing classes with existing data is likely to break things.

You can load new code into new class loaders relatively easily:

ClassLoader loader = URLClassLoader.newInstance(
    new URL[] { yourURL },
    getClass().getClassLoader()
);
Class<?> clazz = Class.forName("mypackage.MyClass", true, loader);
Class<? extends Runnable> runClass = clazz.asSubclass(Runnable.class);
// Avoid Class.newInstance, for it is evil.
Constructor<? extends Runnable> ctor = runClass.getConstructor();
Runnable doRun = ctor.newInstance();
doRun.run();

Class loaders no longer used can be garbage collected (unless there is a memory leak, as is often the case with using ThreadLocal, JDBC drivers, java.beans, etc).

If you want to keep the object data, then I suggest a persistence mechanism such as Serialisation, or whatever you are used to.

Of course debugging systems can do fancier things, but are more hacky and less reliable.

It is possible to add new classes into a class loader. For instance, using URLClassLoader.addURL. However, if a class fails to load (because, say, you haven't added it), then it will never load in that class loader instance.

Update pandas 0.17.0

@7stud's answer for the newest pandas version would require to just call

s.plot( 
    kind='bar', 
    color=my_colors,
)

instead of

pd.Series.plot(
    s, 
    kind='bar', 
    color=my_colors,
)

The plotting functions have become members of the Series, DataFrame objects and in fact calling pd.Series.plot with a color argument gives an error

Technically, you can use StackTrace, but this is very slow and will not give you the answers you expect a lot of the time. This is because during release builds optimizations can occur that will remove certain method calls. Hence you can't be sure in release whether stacktrace is "correct" or not.

Really, there isn't any foolproof or fast way of doing this in C#. You should really be asking yourself why you need this and how you can architect your application, so you can do what you want without knowing which method called it.

There is a step by step explanation (with pictures) available @ Restore DataBase

1. Click Start, select All Programs, click Microsoft SQL Server 2008 and select SQL Server Management Studio.
   This will bring up the Connect to Server dialog box.
   Ensure that the Server name YourServerName and that Authentication is set to Windows Authentication.
   Click Connect.

2. On the right, right-click Databases and select Restore Database.
   This will bring up the Restore Database window.

3. On the Restore Database screen, select the From Device radio button and click the "..." box.
   This will bring up the Specify Backup screen.

4. On the Specify Backup screen, click Add.
   This will bring up the Locate Backup File.

5. Select the DBBackup folder and chose your BackUp File(s).

6. On the Restore Database screen, under Select the backup sets to restore: place a check in the Restore box, next to your data and in the drop-down next to To database: select DbName.

7. You're done.

For the list example, use a comprehension:

>>> l = ['ll', 'xx', 'll']
>>> print [n for (n, e) in enumerate(l) if e == 'll']
[0, 2]

Similarly for strings:

>>> text = "Allowed Hello Hollow"
>>> print [n for n in xrange(len(text)) if text.find('ll', n) == n]
[1, 10, 16]

this will list adjacent runs of "ll', which may or may not be what you want:

>>> text = 'Alllowed Hello Holllow'
>>> print [n for n in xrange(len(text)) if text.find('ll', n) == n]
[1, 2, 11, 17, 18]

Configure After pushing the code when you get a rejected message, click on configure and click Add spec as shown in this picture

Drop down and click on the ref/heads/yourbranchname and click on Add Spec again

Finally save and push the code to the repo

BEGIN-END blocks are the building blocks of PL/SQL, and each PL/SQL unit is contained within at least one such block. Nesting BEGIN-END blocks within PL/SQL blocks is usually done to trap certain exceptions and handle that special exception and then raise unrelated exceptions. Nevertheless, in PL/SQL you (the client) must always issue a commit or rollback for the transaction.

If you wish to have atomic transactions within a PL/SQL containing transaction, you need to declare a PRAGMA AUTONOMOUS_TRANSACTION in the declaration block. This will ensure that any DML within that block can be committed or rolledback independently of the containing transaction.

However, you cannot declare this pragma for nested blocks. You can only declare this for:

• Top-level (not nested) anonymous PL/SQL blocks
• List item
• Local, standalone, and packaged functions and procedures
• Methods of a SQL object type
• Database triggers

HTTP Authorization header problem can be addressed with the following:

var ws = new WebSocket("ws://username:[email protected]/service");

Then, a proper Basic Authorization HTTP header will be set with the provided username and password. If you need Basic Authorization, then you're all set.

I want to use Bearer however, and I resorted to the following trick: I connect to the server as follows:

var ws = new WebSocket("ws://[email protected]/service");

And when my code at the server side receives Basic Authorization header with non-empty username and empty password, then it interprets the username as a token.

In order to build your repo after new commits, use Bitbucket Plugin.

There is just one thing to notice: When creating a POST Hook (notice that it is POST hook, not Jenkins hook), the URL works when it has a "/" in the end. Like:

URL: JENKINS_URL/bitbucket-hook/
e.g. someAddress:8080/bitbucket-hook/

Do not forget to check "Build when a change is pushed to Bitbucket" in your job configuration.

As from Android developer guide :

"orientation" The screen orientation has changed — the user has rotated the device. Note: If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.

"screenSize" The current available screen size has changed. This represents a change in the currently available size, relative to the current aspect ratio, so will change when the user switches between landscape and portrait. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device). Added in API level 13.

So, in the AndroidManifest.xml file, we can put:

<activity
            android:name=".activities.role_activity.GeneralViewPagerActivity"
            android:label="@string/title_activity_general_view_pager"
            android:screenOrientation="portrait"
            android:configChanges="orientation|keyboardHidden|screenSize"
            >
        </activity> 

Instead of writing the code from the scratch you can use jquery plug in. Such plug in can provide many configuration option as well.

Here is the one I most liked.

Also possible to use reduce in Java 8 to solve this problem:

int res = "abdsd3$asda$asasdd$sadas".chars().reduce(0, (a, c) -> a + (c == '$' ? 1 : 0));
System.out.println(res);

Output:

The simplest way is to use the following pattern:

http://[server]/[site]/[ListName]/[Folder]/[SubFolder]

To place a shortcut to a document library:

1. Upload it as *.url file. However, by default, this file type is not allowed.
2. Go to you Document Library settings > Advanced Settings > Allow management of content types. Add the "Link to document" content type to a document library and paste the link

Neither dynamic, nor JObject.FromObject solution works when you have JSON properties that are not valid C# variable names e.g. "@odata.etag". I prefer the indexer initializer syntax in my test cases:

JObject jsonObject = new JObject
{
    ["Date"] = DateTime.Now,
    ["Album"] = "Me Against The World",
    ["Year"] = 1995,
    ["Artist"] = "2Pac"
};

Having separate set of enclosing symbols for initializing JObject and for adding properties to it makes the index initializers more readable than classic object initializers, especially in case of compound JSON objects as below:

JObject jsonObject = new JObject
{
    ["Date"] = DateTime.Now,
    ["Album"] = "Me Against The World",
    ["Year"] = 1995,
    ["Artist"] = new JObject
    {
        ["Name"] = "2Pac",
        ["Age"] = 28
    }
};

With object initializer syntax, the above initialization would be:

JObject jsonObject = new JObject
{
    { "Date", DateTime.Now },
    { "Album", "Me Against The World" },
    { "Year", 1995 }, 
    { "Artist", new JObject
        {
            { "Name", "2Pac" },
            { "Age", 28 }
        }
    }
};

For simple animations you can use an animated gif. I'm using one in this README file for instance.

As per the DOM structure you can use below code:

var x = document.getElementById('mySelect');
     var txt = "";
     var val = "";
     for (var i = 0; i < x.length; i++) {
         txt +=x[i].text + ",";
         val +=x[i].value + ",";
      }

Developers also take care about accessibility.

Do not use onClick on images without defining the ARIA role.

Non-interactive HTML elements and non-interactive ARIA roles indicate content and containers in the user interface. A non-interactive element does not support event handlers (mouse and key handlers).

The developer and designers are responsible for providing the expected behavior of an element that the role suggests it would have: focusability and key press support. More info see WAI-ARIA Authoring Practices Guide - Design Patterns and Widgets.

tldr; this is how it should be done:

    src="pond1.jpg"
    alt="pic id code"
    onClick="window.open(this.src)"
    role="button"
    tabIndex="0"
  />

Try the following:

boolean isDebuggable =  ( 0 != ( getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE ) );

Kotlin:

val isDebuggable = 0 != applicationInfo.flags and ApplicationInfo.FLAG_DEBUGGABLE

It is taken from bundells post from here

This flexbox principle also works horizontally

During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Setting an automatic left margin for the Last Item will do the work.

.last-item {
  margin-left: auto;
}

Code Example:

.container {_x000D_
  display: flex;_x000D_
  width: 400px;_x000D_
  outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
  margin: 5px;_x000D_
  background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
  margin-left: auto;_x000D_
}

<div class="container">_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p class="last-item"></p>_x000D_
</div>

I faced same issue, I have installed two java version hence it caused this issue. to confirm this go and click java icon in control panel if doesnt open then issue is same, just go and uninstall one version. piece of cake. thanks.

This solution will work regardless of the number of char variables you have:

char c1 = 'z';
char c2 = 'w';
std::string s1{c1};
std::string s12{c1, c2};

Just adding that using the first approach it can be done as -

pd.DataFrame(list(map(list, zip(lst1,lst2,lst3))))

Plase check application pool. if it is stoped. restart it.

you can use the command reset

git reset --soft HEAD^1

then:

git reset <files>
git commit --amend

and

git push -f

I have always tested the number of open workbooks in Workbook_Open(). If it is 1, then the workbook was opened by the command line (or the user closed all the workbooks, then opened this one).

If Workbooks.Count = 1 Then

    ' execute the macro or call another procedure - I always do the latter  
    PublishReport

    ThisWorkbook.Save

    Application.Quit

End If

-Wall and -Werror compiler options can cause it, please check if those are used in compiler settings.

Here is the best option scroll to bottom for table grid, it will be scroll to the last row of the table grid :

 $('.add-row-btn').click(function () {
     var tempheight = $('#PtsGrid > table').height();
     $('#PtsGrid').animate({
         scrollTop: tempheight
         //scrollTop: $(".scroll-bottom").offset().top
     }, 'slow');
 });

Use string concatenation:

href={'/posts/' + post.id}

The JSX syntax allows either to use strings or expressions ({...}) as values. You cannot mix both. Inside an expression you can, as the name suggests, use any JavaScript expression to compute the value.

1. You need to create a class that holds the user values, just like the response class User.

2. Add a property to the Response class 'user' with the type of the new class for the user values User.

   public class Response {
   
       public string id { get; set; }
       public string text { get; set; }
       public string url { get; set; }
       public string width { get; set; }
       public string height { get; set; }
       public string size { get; set; }
       public string type { get; set; }
       public string timestamp { get; set; }
       public User user { get; set; }
   
   }
   
   public class User {
   
       public int id { get; set; }
       public string screen_name { get; set; }
   
   }
   

In general you should make sure the property types of the json and your CLR classes match up. It seems that the structure that you're trying to deserialize contains multiple number values (most likely int). I'm not sure if the JavaScriptSerializer is able to deserialize numbers into string fields automatically, but you should try to match your CLR type as close to the actual data as possible anyway.

With log4j 1.x I find the best way is to use a DOMConfigurator to submit one of a predefined set of XML log configurations (say, one for normal use and one for debugging).

Making use of these can be done with something like this:

  public static void reconfigurePredefined(String newLoggerConfigName) {
    String name = newLoggerConfigName.toLowerCase();
    if ("default".equals(name)) {
      name = "log4j.xml";
    } else {
      name = "log4j-" + name + ".xml";
    }

    if (Log4jReconfigurator.class.getResource("/" + name) != null) {
      String logConfigPath = Log4jReconfigurator.class.getResource("/" + name).getPath();
      logger.warn("Using log4j configuration: " + logConfigPath);
      try (InputStream defaultIs = Log4jReconfigurator.class.getResourceAsStream("/" + name)) {
        new DOMConfigurator().doConfigure(defaultIs, LogManager.getLoggerRepository());
      } catch (IOException e) {
        logger.error("Failed to reconfigure log4j configuration, could not find file " + logConfigPath + " on the classpath", e);
      } catch (FactoryConfigurationError e) {
        logger.error("Failed to reconfigure log4j configuration, could not load file " + logConfigPath, e);
      }
    } else {
      logger.error("Could not find log4j configuration file " + name + ".xml on classpath");
    }
  }

Just call this with the appropriate config name, and make sure that you put the templates on the classpath.

Try to just use isNotNull function.

df.filter(df.dt_mvmt.isNotNull()).count()

Well, you are using both frame.setSize() and frame.pack().

You should use one of them at one time.

Using setSize() you can give the size of frame you want but if you use pack(), it will automatically change the size of the frames according to the size of components in it. It will not consider the size you have mentioned earlier.

Try removing frame.pack() from your code or putting it before setting size and then run it.

In addition to the points in other answers: one thing to note if you are using quotes in Excel is the placement of your spaces. If you have a line of code like this:

print '%s, "%s", "%s", "%s"' % (value_1, value_2, value_3, value_4)

Excel will treat the initial quote as a literal quote instead of using it to escape commas. Your code will need to change to

print '%s,"%s","%s","%s"' % (value_1, value_2, value_3, value_4)

It was this subtlety that brought me here.

Have modified @user919216 code .. and made it compatible with WebView

You can get a JSON file that maps country codes to phone codes from http://country.io/phone.json:

...
BD: "880",
BE: "32",
BF: "226",
BG: "359",
BA: "387",
...

If you want country names then http://country.io/names.json will give you that:

...
"AL": "Albania",
"AM": "Armenia",
"AO": "Angola",
"AQ": "Antarctica",
"AR": "Argentina",
...

See http://country.io/data for more details.

[MySQL]

In these (very rare) cases:

• two tables that really need different collation types

• values not coming from a table, but from an explicit enumeration, for instance:

  SELECT 1 AS numbers UNION ALL SELECT 2 UNION ALL SELECT 3

you can compare the values between the different tables by using CAST or CONVERT:

CAST('my text' AS CHAR CHARACTER SET utf8)

CONVERT('my text' USING utf8)

See CONVERT and CAST documentation on MySQL website.

Ram Narasimhan explained the concept very nicely here below is an alternative explanation through the code example of Naive Bayes in action
It uses an example problem from this book on page 351
This is the data set that we will be using

In the above dataset if we give the hypothesis = {"Age":'<=30', "Income":"medium", "Student":'yes' , "Creadit_Rating":'fair'} then what is the probability that he will buy or will not buy a computer.
The code below exactly answers that question.
Just create a file called named new_dataset.csv and paste the following content.

Age,Income,Student,Creadit_Rating,Buys_Computer
<=30,high,no,fair,no
<=30,high,no,excellent,no
31-40,high,no,fair,yes
>40,medium,no,fair,yes
>40,low,yes,fair,yes
>40,low,yes,excellent,no
31-40,low,yes,excellent,yes
<=30,medium,no,fair,no
<=30,low,yes,fair,yes
>40,medium,yes,fair,yes
<=30,medium,yes,excellent,yes
31-40,medium,no,excellent,yes
31-40,high,yes,fair,yes

The recommended way to style the Toolbar for a Light.DarkActionBar clone would be to use Theme.AppCompat.Light.DarkActionbar as parent/app theme and add the following attributes to the style to hide the default ActionBar:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

Then use the following as your Toolbar:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>

For further modifications, you would create styles extending ThemeOverlay.AppCompat.Dark.ActionBar and ThemeOverlay.AppCompat.Light replacing the ones within AppBarLayout->android:theme and Toolbar->app:popupTheme. Also note that this will pick up your ?attr/colorPrimary if you have set it in your main style so you might get a different background color.

You will find a good example of this is in the current project template with an Empty Activity of Android Studio (1.4+).

Standard xargs has no good way to do it; you're better off using find -exec as someone else suggested, or wrap the sed in a script which does nothing if there are no arguments. GNU xargs has the --no-run-if-empty option, and BSD / OS X xargs has the -L option which looks like it should do something similar.

It's Tomcat bug.

Today 12/02/2017 newest official version from Debian repositories is Tomcat 8.0.14

Solution is to download from official site and install newest package of Tomcat 8, 8.5, 9 or upgrade to newest version(8.5.x) from jessie-backports

Debian 8

Add to /etc/apt/sources.list

deb http://ftp.debian.org/debian jessie-backports main

Then update and install Tomcat from jessie-backports

sudo apt-get update && sudo apt-get -t jessie-backports install tomcat8

You can always use this, taken from Microsofts website.

static void Main()
{
    // Copy from the current directory, include subdirectories.
    DirectoryCopy(".", @".\temp", true);
}

private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
    // Get the subdirectories for the specified directory.
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);

    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    DirectoryInfo[] dirs = dir.GetDirectories();
    // If the destination directory doesn't exist, create it.
    if (!Directory.Exists(destDirName))
    {
        Directory.CreateDirectory(destDirName);
    }

    // Get the files in the directory and copy them to the new location.
    FileInfo[] files = dir.GetFiles();
    foreach (FileInfo file in files)
    {
        string temppath = Path.Combine(destDirName, file.Name);
        file.CopyTo(temppath, false);
    }

    // If copying subdirectories, copy them and their contents to new location.
    if (copySubDirs)
    {
        foreach (DirectoryInfo subdir in dirs)
        {
            string temppath = Path.Combine(destDirName, subdir.Name);
            DirectoryCopy(subdir.FullName, temppath, copySubDirs);
        }
    }

You can get accurate Carousel effect using iCarousel SDK.

You can get an instant Cover Flow effect on iOS by using the marvelous and free iCarousel library. You can download it from https://github.com/nicklockwood/iCarousel and drop it into your Xcode project fairly easily by adding a bridging header (it's written in Objective-C).

If you haven't added Objective-C code to a Swift project before, follow these steps:

• Download iCarousel and unzip it
• Go into the folder you unzipped, open its iCarousel subfolder, then select iCarousel.h and iCarousel.m and drag them into your project navigation – that's the left pane in Xcode. Just below Info.plist is fine.
• Check "Copy items if needed" then click Finish.
• Xcode will prompt you with the message "Would you like to configure an Objective-C bridging header?" Click "Create Bridging Header" You should see a new file in your project, named YourProjectName-Bridging-Header.h.
• Add this line to the file: #import "iCarousel.h"
• Once you've added iCarousel to your project you can start using it.
• Make sure you conform to both the iCarouselDelegate and iCarouselDataSource protocols.

Swift 3 Sample Code:

    override func viewDidLoad() {
      super.viewDidLoad()
      let carousel = iCarousel(frame: CGRect(x: 0, y: 0, width: 300, height: 200))
      carousel.dataSource = self
      carousel.type = .coverFlow
      view.addSubview(carousel) 
    }

   func numberOfItems(in carousel: iCarousel) -> Int {
        return 10
    }

    func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
        let imageView: UIImageView

        if view != nil {
            imageView = view as! UIImageView
        } else {
            imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 128, height: 128))
        }

        imageView.image = UIImage(named: "example")

        return imageView
    }

You don't have to do this locally either. You can do it through a remote repository, for example:

svn export http://<repo>/process/test.txt /path/to/code/

In Sublime Text, after you select multiple regions of text, a click is considered a way to exit the multi-select mode. Move the cursor with the keyboard keys (arrows, Ctrl+arrows, etc.) instead, and you'll be fine

for SQL > odd:

select * from id in(select id from employee where id%2=1)

for SQL > Even:

select * from id in(select id from employee where id%2=0).....f5

It is actually a 3 step process to connect to a PostgreSQL server remotely through pgAdmin3.

Note: I use Ubuntu 11.04 and PostgreSQL 8.4.

1. You have to make PostgreSQL listening for remote incoming TCP connections because the default settings allow to listen only for connections on the loopback interface. To be able to reach the server remotely you have to add the following line into the file /etc/postgresql/8.4/main/postgresql.conf:

   listen_addresses = '*'

2. PostgreSQL by default refuses all connections it receives from any remote address, you have to relax these rules by adding this line to /etc/postgresql/8.4/main/pg_hba.conf:

   host all all 0.0.0.0/0 md5

   This is an access control rule that let anybody login in from any address if he can provide a valid password (the md5 keyword). You can use needed network/mask instead of 0.0.0.0/0 .

3. When you have applied these modifications to your configuration files you need to restart PostgreSQL server. Now it is possible to login to your server remotely, using the username and password.

All of the answers here now contain the old behavior of maps. In Go 1.12+, you can just print a map value and it will be sorted by key automatically. This has been added because it allows the testing of map values easily.

func main() {
    m := map[int]int{3: 5, 2: 4, 1: 3}
    fmt.Println(m)

    // In Go 1.12+
    // Output: map[1:3 2:4 3:5]

    // Before Go 1.12 (the order was undefined)
    // map[3:5 2:4 1:3]
}

Maps are now printed in key-sorted order to ease testing. The ordering rules are:

• When applicable, nil compares low
• ints, floats, and strings order by <
• NaN compares less than non-NaN floats
• bool compares false before true
• Complex compares real, then imaginary
• Pointers compare by machine address
• Channel values compare by machine address
• Structs compare each field in turn
• Arrays compare each element in turn
• Interface values compare first by reflect.Type describing the concrete type and then by concrete value as described in the previous rules.

When printing maps, non-reflexive key values like NaN were previously displayed as <nil>. As of this release, the correct values are printed.

Two problems:

1 - You never told Git to start tracking any file

You write that you ran

git init
git commit -m "first commit"

and that, at that stage, you got

nothing added to commit but untracked files present (use "git add" to track).

Git is telling you that you never told it to start tracking any files in the first place, and it has nothing to take a snapshot of. Therefore, Git creates no commit. Before attempting to commit, you should tell Git (for instance):

Hey Git, you see that README.md file idly sitting in my working directory, there? Could you put it under version control for me? I'd like it to go in my first commit/snapshot/revision...

For that you need to stage the files of interest, using

git add README.md

before running

git commit -m "some descriptive message"

2 - You haven't set up the remote repository

You then ran

git remote add origin https://github.com/VijayNew/NewExample.git

After that, your local repository should be able to communicate with the remote repository that resides at the specified URL (https://github.com/VijayNew/NewExample.git)... provided that remote repo actually exists! However, it seems that you never created that remote repo on GitHub in the first place: at the time of writing this answer, if I try to visit the correponding URL, I get

Before attempting to push to that remote repository, you need to make sure that the latter actually exists. So go to GitHub and create the remote repo in question. Then and only then will you be able to successfully push with

git push -u origin master

In your R script, called test.R:

args <- commandArgs(trailingOnly = F)
myargument <- args[length(args)]
myargument <- sub("-","",myargument)
print(myargument)
q(save="no")

From the command line run:

R CMD BATCH -4 test.R

Your output file, test.Rout, will show that the argument 4 has been successfully passed to R:

cat test.Rout

> args <- commandArgs(trailingOnly = F)
> myargument <- args[length(args)]
> myargument <- sub("-","",myargument)
> print(myargument)
[1] "4"
> q(save="no")
> proc.time()
user  system elapsed 
0.222   0.022   0.236 

Try using

window.parent.window.location.href = 'http://google.com'

x(end+1) = newElem is a bit more robust.

x = [x newElem] will only work if x is a row-vector, if it is a column vector x = [x; newElem] should be used. x(end+1) = newElem, however, works for both row- and column-vectors.

In general though, growing vectors should be avoided. If you do this a lot, it might bring your code down to a crawl. Think about it: growing an array involves allocating new space, copying everything over, adding the new element, and cleaning up the old mess...Quite a waste of time if you knew the correct size beforehand :)

What you need are character classes. In that, you've only to worry about the ], \ and - characters (and ^ if you're placing it straight after the beginning of the character class "[" ).

Syntax: [characters] where characters is a list with characters.

Example:

var cleanString = dirtyString.replace(/[|&;$%@"<>()+,]/g, "");

You are really asking a couple of questions here:

1) Why does the price of SSL certificates vary so much

2) Where can I get good, cheap SSL certificates?

The first question is a good one. For example, the type of SSL certificate you buy is important. Many SSL certificates are domain verified only - that is, the company issuing the certificate only validate that you own the domain. They don't validate your identity, so people visiting your site might know that the domain has a SSL certificate, but that doesn't mean the person behing the website isn't a scammer or phisher, for example. This is why the Verisign solution is much more expensive - you are getting a cert that not only secures your site, but validates the identity of the owner of the site (well, that's the claim).

You can read more on this subject here

For your second question, I can personally recommend RapidSSL. I've bought several certificates from them in the past and they are, well, rapid. However, you should always do your research first. A company based in France might be better for you to deal with as you can get support in your local hours, etc.

A little intro to dictionary

d={'a':'apple','b':'ball'}
d.keys()  # displays all keys in list
['a','b']
d.values() # displays your values in list
['apple','ball']
d.items() # displays your pair tuple of key and value
[('a','apple'),('b','ball')

Print keys,values method one

for x in d.keys():
    print x +" => " + d[x]

Another method

for key,value in d.items():
    print key + " => " + value

You can get keys using iter

>>> list(iter(d))
['a', 'b']

You can get value of key of dictionary using get(key, [value]):

d.get('a')
'apple'

If key is not present in dictionary,when default value given, will return value.

d.get('c', 'Cat')
'Cat'

The pack syntax you are using here is for an image that is contained as a Resource within your application, not for a loose file in the file system.

You simply want to pass the actual path to the UriSource:

logo.UriSource = new Uri(@"\\myserver\folder1\Customer Data\sample.png");

Label myLabel = new Label (); myLabel.Content = "Hello World!";

Most of the suggested solutions can cause a 1 day error depending on the time associated with each date. If you are looking for an integer number of calendar days between to dates, regardless of the time associated with each date, I have found that this works well:

return (dateOne.Value.Date - dateTwo.Value.Date).Days;

The Lazy<T> version:

public sealed class Singleton
{
    private static readonly Lazy<Singleton> lazy
        = new Lazy<Singleton>(() => new Singleton());

    public static Singleton Instance
        => lazy.Value;

    private Singleton() { }
}

Requires .NET 4 and C# 6.0 (VS2015) or newer.

Safer and faster (doubling capacity) version:

char *readline(char *prompt) {
  size_t size = 80;
  char *str = malloc(sizeof(char) * size);
  int c;
  size_t len = 0;
  printf("%s", prompt);
  while (EOF != (c = getchar()) && c != '\r' && c != '\n') {
    str[len++] = c;
    if(len == size) str = realloc(str, sizeof(char) * (size *= 2));
  }
  str[len++]='\0';
  return realloc(str, sizeof(char) * len);
}

RDP will not do that natively.

As other answers have said -- you'll need to do some scripting and make policy changes as a kludge to make it hard for RDP logins to run anything but the intended application.

However, as of 2008, Microsoft has released application virtualization technology via Terminal Services that will allow you to do this seamlessly.

If you have a built-in command of GridView like insert, update or delete, on row command you can use the following code to get the index:

int index = Convert.ToInt32(e.CommandArgument);

In a custom command, you can set the command argument to yourRow.RowIndex.ToString() and then get it back in the RowCommand event handler. Unless, of course, you need the command argument for another purpose.

Given the following question :

Write code to remove the duplicate characters in a string without using any additional buffer. NOTE: One or two additional variables are fine. An extra copy of the array is not.

Since one or two additional variables are fine but no buffer is allowed, you can simulate the behaviour of a hashmap by using an integer to store bits instead. This simple solution runs at O(n), which is faster than yours. Also, it isn't conceptually complicated and in-place :

    public static void removeDuplicates(char[] str) {
        int map = 0;
        for (int i = 0; i < str.length; i++) {
            if ((map & (1 << (str[i] - 'a'))) > 0) // duplicate detected
                str[i] = 0;
            else // add unique char as a bit '1' to the map
                map |= 1 << (str[i] - 'a');
        }
    }

The drawback is that the duplicates (which are replaced with 0's) will not be placed at the end of the str[] array. However, this can easily be fixed by looping through the array one last time. Also, an integer has the capacity for only regular letters.

You can use a heredoc. e.g. from a prompt:

$ sqlplus -s username/password@oracle_instance <<EOF
set feed off
set pages 0
select count(*) from table;
exit
EOF

so sqlplus will consume everything up to the EOF marker as stdin.

This may be an option. Hope there is a better way to start from last element than to while loop to the end.

public static void main(String[] args) {        
    List<String> a = new ArrayList<String>();
    a.add("1");a.add("2");a.add("3");a.add("4");a.add("5");

    ListIterator<String> aIter=a.listIterator();        
    while(aIter.hasNext()) aIter.next();

    for (;aIter.hasPrevious();)
    {
        String aVal = aIter.previous();
        System.out.println(aVal);           
    }
}

Based on @AdilSoomro's great answer. I have come up with this:

@interface MKMapView (ZoomLevel)
- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
                  zoomLevel:(NSUInteger)zoomLevel
                   animated:(BOOL)animated;

-(double) getZoomLevel;
@end



@implementation MKMapView (ZoomLevel)

- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
                  zoomLevel:(NSUInteger)zoomLevel animated:(BOOL)animated {
    MKCoordinateSpan span = MKCoordinateSpanMake(0, 360/pow(2, zoomLevel)*self.frame.size.width/256);
    [self setRegion:MKCoordinateRegionMake(centerCoordinate, span) animated:animated];
}


-(double) getZoomLevel {
    return log2(360 * ((self.frame.size.width/256) / self.region.span.longitudeDelta));
}

@end

Update for intellij idea 2017 3.2

First thing I wann ans to this imp question: "Why we require PATH To be set?"

Answer : You need to set PATH to compile Java source code, create JAVA CLASS FILES and allow Operating System to load classes at runtime.

Now you will understand why after setting "javac" you can manually compile by just saying "Class_name.java"

Modify the PATH of Windows Environmental Variable by appending the location till bin directory where all exe file(for eg. java,javac) are present.

Example : ;C:\Program Files\Java\jre7\bin.

If you want to see a more detailed discussion of differences for the commands, see the Details about Differences section, below.

From the LeMoDa.net website¹ (archived), specifically the Windows and Unix command line equivalents page (archived), I found the following². There's a better/more complete table in the next edit.

Windows command     Unix command
rmdir               rmdir
rmdir /s            rm -r
move                mv

I'm interested to hear from @Dave and @javadba to hear how equivalent the commands are - how the "behavior and capabilities" compare, whether quite similar or "woefully NOT equivalent".

All I found out was that when I used it to try and recursively remove a directory and its constituent files and subdirectories, e.g.

(Windows cmd)>rmdir /s C:\my\dirwithsubdirs\

gave me a standard Windows-knows-better-than-you-do-are-you-sure message and prompt

dirwithsubdirs, Are you sure (Y/N)?

and that when I typed Y, the result was that my top directory and its constituent files and subdirectories went away.

Edit

I'm looking back at this after finding this answer. I retried each of the commands, and I'd change the table a little bit.

Windows command     Unix command
rmdir               rmdir
rmdir /s /q         rm -r
rmdir /s /q         rm -rf
rmdir /s            rm -ri
move                mv
del <file>          rm <file>

If you want the equivalent for

rm -rf

you can use

rmdir /s /q

or, as the author of the answer I sourced described,

But there is another "old school" way to do it that was used back in the day when commands did not have options to suppress confirmation messages. Simply ECHO the needed response and pipe the value into the command.

echo y | rmdir /s

Details about Differences

I tested each of the commands using Windows CMD and Cygwin (with its bash).

Before each test, I made the following setup.

Windows CMD

>mkdir this_directory
>echo some text stuff > this_directory/some.txt
>mkdir this_empty_directory

Cygwin bash

$ mkdir this_directory
$ echo "some text stuff" > this_directory/some.txt
$ mkdir this_empty_directory

That resulted in the following file structure for both.

base
|-- this_directory
|   `-- some.txt
`-- this_empty_directory

Here are the results. Note that I'll not mark each as CMD or bash; the CMD will have a > in front, and the bash will have a $ in front.

RMDIR

>rmdir this_directory
The directory is not empty.

>tree /a /f .

> rmdir this_empty_directory

>tree /a /f .
base
\---this_directory
        some.txt

$ rmdir this_directory
rmdir: failed to remove 'this_directory': Directory not empty

$ tree --charset=ascii
base

`-- this_empty_directory

2 directories, 1 file

$ rmdir this_empty_directory

$ tree --charset=ascii
base
`-- this_directory
    `-- some.txt

RMDIR /S /Q and RM -R ; RM -RF

>rmdir /s /q this_directory

>tree /a /f
base
\---this_empty_directory

>rmdir /s /q this_empty_directory

>tree /a /f
base
No subfolders exist

$ rm -r this_directory

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -r this_empty_directory

$ tree --charset=ascii
base
0 directories, 0 files

$ rm -rf this_directory

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -rf this_empty_directory

$ tree --charset=ascii
base
0 directories, 0 files

RMDIR /S AND RM -RI Here, we have a bit of a difference, but they're pretty close.

>rmdir /s this_directory
this_directory, Are you sure (Y/N)? y

>tree /a /f
base
\---this_empty_directory

>rmdir /s this_empty_directory
this_empty_directory, Are you sure (Y/N)? y

>tree /a /f
base
No subfolders exist

$ rm -ri this_directory
rm: descend into directory 'this_directory'? y
rm: remove regular file 'this_directory/some.txt'? y
rm: remove directory 'this_directory'? y

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -ri this_empty_directory
rm: remove directory 'this_empty_directory'? y

$ tree --charset=ascii
base
0 directories, 0 files

I'M HOPING TO GET A MORE THOROUGH MOVE AND MV TEST

Notes

1. I know almost nothing about the LeMoDa website, other than the fact that the info is

(archived copyright notice)

and that there seem to be a bunch of useful programming tips along with some humour (yes, the British spelling) and information on how to fix Japanese toilets. I also found some stuff talking about the "Ibaraki Report", but I don't know if that is the website.

I think I shall go there more often; it's quite useful. Props to Ben Bullock, whose email is on his page. If he wants me to remove this info, I will.

2. Actually, I found the information with a Google search for "cmd equivalent of rm"

https://www.google.com/search?q=cmd+equivalent+of+rm

The information I'm sharing came up first.

del statement does not delete an instance, it merely deletes a name.

When you do del i, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.

If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.

If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.

>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst     # memory is released

If you created some variables, you have to delete them all.

>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst     # memory release now

Maybe you can build a function / static class Method that does exactly that. I use Kohana which has a nice function called:

Kohana::Debug

That will do what you want. That's reduces it to only one line. A simple function will look like

function debug($input) {
    echo "<pre>";
    print_r($input);
    echo "</pre>";
}

SELECT
    IF city='C7'
    THEN city
    ELSE 'somethingelse'
    END as `city`
FROM `table` WHERE `city` = 'c7'

I do so.

List<Object> list = new List<Object>();

if(list.Count>0){
  Object obj = list[0];
}

The answer is given in @dku-rajkumar post.

ArrayList commonList = CollectionUtils.retainAll(list1,list2);

There are situations where you can't use the (quite convincing) with... for... structure. In that case, do the following:

line = self.fo.readline()
if len(line) != 0:
     if 'str' in line:
         break

This will work because the the readline() leaves a trailing newline character, where as EOF is just an empty string.

Here is a way to do it that works, but may not be best practise for any language really:

var x,y;
x='something';
y=1;
undefined === y || (x = y);

alternatively

undefined !== y && (x = y);

This also helps when you have previous stack activity stored in stack.

I had this issue in Android Studio 3.1 :

I only have on board graphics. Went to Tools -> AVD Manager -> (Edit this AVD) under Actions -> Emulated Performance (Graphics): select "Software GLES 2.0".

I've been struggling all morning to get ONLY landscape left/right supported properly. I discovered something really annoying; although the "General" tab allows you to deselect "Portrait" for device orientation, you have to edit the plist itself to disable Portrait and PortraitUpsideDown INTERFACE orientations - it's the last key in the plist: "Supported Interface Orientations".

The other thing is that it seems you must use the "mask" versions of the enums (e.g., UIInterfaceOrientationMask.LandscapeLeft), not just the orientation one. The code that got it working for me (in my main viewController):

override func shouldAutorotate() -> Bool {
    return true
}

override func supportedInterfaceOrientations() -> Int {
    return Int(UIInterfaceOrientationMask.LandscapeLeft.rawValue) | Int(UIInterfaceOrientationMask.LandscapeRight.rawValue)
}

Making this combination of plist changes and code is the only way I've been able to get it working properly.

On your asp.net page add the gridview

<asp:GridView ID="GridView1" onrowdatabound="GridView1_RowDataBound" >
</asp:GridView>

Create a method protected void method in your c# class called GridView1_RowDataBound

as

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        e.Row.Cells[0].Text = "HeaderText";
    }
}

Everything should be working fine.

One can also receive this error if using the new (so far webkit only) notification feature before getting permission.

First run:

<!-- Get permission -->
<button onclick="webkitNotifications.requestPermission();">Enable Notifications</button>

Later run:

// Display Notification:
window.webkitNotifications.createNotification('image', 'Title', 'Body').show();

The request permission functions needs to be triggered from an event caused by the user, otherwise it won't be displayed.

Using update directly is more efficient and could also prevent integrity problems.

From the official documentation https://docs.djangoproject.com/en/3.0/ref/models/querysets/#django.db.models.query.QuerySet.update

If you’re just updating a record and don’t need to do anything with the model object, the most efficient approach is to call update(), rather than loading the model object into memory. For example, instead of doing this:

e = Entry.objects.get(id=10)
e.comments_on = False
e.save()

…do this:

Entry.objects.filter(id=10).update(comments_on=False)

Using update() also prevents a race condition wherein something might change in your database in the short period of time between loading the object and calling save().

SELECT * FROM users WHERE created >= now()

When you write .class after a class name, it references the class literal - java.lang.Class object that represents information about given class.

For example, if your class is Print, then Print.class is an object that represents the class Print on runtime. It is the same object that is returned by the getClass() method of any (direct) instance of Print.

Print myPrint = new Print();
System.out.println(Print.class.getName());
System.out.println(myPrint.getClass().getName());

You could write a script to update the FK's for you.. check out this blog: http://multunus.com/2011/03/how-to-easily-merge-two-identical-mysql-databases/

They have a clever script to use the information_schema tables to get the "id" columns:

SET @db:='id_new'; 

select @max_id:=max(AUTO_INCREMENT) from information_schema.tables;

select concat('update ',table_name,' set ', column_name,' = ',column_name,'+',@max_id,' ; ') from information_schema.columns where table_schema=@db and column_name like '%id' into outfile 'update_ids.sql';

use id_new
source update_ids.sql;

You can work around this known bug in OpenJDK with this:

Map<Integer, Boolean> collect = list.stream()
        .collect(HashMap::new, (m,v)->m.put(v.getId(), v.getAnswer()), HashMap::putAll);

It is not that much pretty, but it works. Result:

1: true
2: true
3: null

(this tutorial helped me the most.)

EDIT:

Unlike Collectors.toMap, this will silently replace values if you have the same key multiple times, as @mmdemirbas pointed out in the comments. If you don't want this, look at the link in the comment.

There is a finishAffinity() method in Activity that will finish the current activity and all parent activities, but it works only in Android 4.1 or higher.

For API 16+, use

finishAffinity();

For lower (Android 4.1 lower), use

ActivityCompat.finishAffinity(YourActivity.this);

I know this thread is a year old, but the real problem is in your working directory.

I believe that the working directory is C:\Users\Administrator\Documents\Mibot\oops\. Please check for the file named socket.py in this directory. Once you find it, rename or move it. When you import socket, socket.py from the current directory is used instead of the socket.py from Python's directory. Hope this helped. :)

Note: Never use the file names from Python's directory to save your program's file name; it will conflict with your program(s).

Install virtual env with

It looks like you're comparing strings incorrectly. To compare a string to another, use the std::string::compare function.

Example

Output (same for all):

Use .splice to remove item from array. Using delete, indexes of the array will not be altered but the value of specific index will be undefined

The splice() method changes the content of an array by removing existing elements and/or adding new elements.

Syntax: array.splice(start, deleteCount[, item1[, item2[, ...]]])

var people = ["Bob", "Sally", "Jack"]_x000D_
var toRemove = 'Bob';_x000D_
var index = people.indexOf(toRemove);_x000D_
if (index > -1) { //Make sure item is present in the array, without if condition, -n indexes will be considered from the end of the array._x000D_
  people.splice(index, 1);_x000D_
}_x000D_
console.log(people);

Edit:

As pointed out by justin-grant, As a rule of thumb, Never mutate this.state directly, as calling setState() afterward may replace the mutation you made. Treat this.state as if it were immutable.

The alternative is, create copies of the objects in this.state and manipulate the copies, assigning them back using setState(). Array#map, Array#filter etc. could be used.

this.setState({people: this.state.people.filter(item => item !== e.target.value);});

I experienced that the javascript: hrefs did not work when the page was embedded in Outlook's webpage feature where a mail folder is set to instead show an url

Filezilla is great and it can support command line arguments.

awk -F"|" '{gsub(/\"/,"|");print "\""$2"\""}' your_file

I had the same problem. Most posted solutions would not work. I ran sfc /scannow and it reported that some errors could not be fixed. To address that problem I ran the command

Dism /Online /Cleanup-Image /RestoreHealth

Ironically, I later found the WAN errors had gone away, the 720 VPN error went away and my VPN worked.

Hard to believe that the WAN errors were corrected by this rather esoteric command, but it's worth a try.

If Windows fails to enumerate the device which is reported in Device Manager as error code 43:

• Install this Compatibility update from Windows.
• If you already have this update but you get this error, restart your PC (unfortunately, it happened to me, I tried everything until I thought what if I restart...).

If the device is listed in Device Manager as Other devices -> Android but reports an error code 28:

• Google USB Driver didn't work for me. You could try your corresponding OEM USB Drivers, but in my case my device is not listed there.
• So, install the latest Samsung drivers: SAMSUNG USB Driver v1.7.23.0
• Restart the computer (very important)
• Go to Device Manager, find the Android device, and select Update Driver Software.
• Select Browse my computer for driver software
• Select Let me pick from a list of device drivers on my computer
• Select ADB Interface from the list
• Select SAMSUNG Android ADB Interface (this is a signed driver). If you get a warning, select Yes to continue.
• Done!

By doing this I was able to use my tablet for development under Windows 8.1.

Note: This solution uses Samsung drivers but works for other devices.

With C++17 you can use a structured binding inside a range-based for loop (adapting John H.'s answer accordingly):

#include <iostream>
#include <map>

int main() {
    std::map<std::string, int> myMap;

    myMap["one"] = 1;
    myMap["two"] = 2;
    myMap["three"] = 3;

    for ( const auto &[key, value]: myMap ) {
        std::cout << key << '\n';
    }
}

Unfortunately the C++17 standard requires you to declare the value variable, even though you're not using it (std::ignore as one would use for std::tie(..) does not work, see this discussion).

Some compilers may therefore warn you about the unused value variable! Compile-time warnings regarding unused variables are a no-go for any production code in my mind. So, this may not be applicable for certain compiler versions.

The way I do it is the following (better than type assertion imho):

onFieldUpdate(event: { target: HTMLInputElement }) {
  this.$emit('onFieldUpdate', event.target.value);
}

This assumes you are only interested in the target property, which is the most common case. If you need to access the other properties of event, a more comprehensive solution involves using the & type intersection operator:

event: Event & { target: HTMLInputElement }

This is a Vue.js version but the concept applies to all frameworks. Obviously you can go more specific and instead of using a general HTMLInputElement you can use e.g. HTMLTextAreaElement for textareas.

android:editable="false" should work, but it is deprecated, you should be using android:inputType="none" instead.

Alternatively, if you want to do it in the code you could do this :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);

This is also a viable alternative :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);

If you're going to make your EditText non-editable, may I suggest using the TextView widget instead of the EditText, since using a EditText seems kind of pointless in that case.

EDIT: Altered some information since I've found that android:editable is deprecated, and you should use android:inputType="none", but there is a bug about it on android code; So please check this.

I just thought I'd chip in on this one. It's been answered perfectly well by others though.

The full main method declaration should be :

 public static void main(final String[] args) throws Exception {

 }

The args are declared final because technically they should not be altered. They are console parameters given by the user.

You should usually specify that main throws Exception so that stack traces can be echoed to console easily without needing to do e.printStackTrace() etc.

As for Array Syntax. I prefer it this way. I suppose that it's a little bit like the difference between french and english. In English it's "a black car", in french it's "a car black". Which is the important noun, car, or black?

I don't like this sort of thing :

String blah[] = {};

What's important here is that it's a String array, so it should be

String[] blah = {};

blah is just a name. I personally think it's a bit of a mistake in Java that arrays can sometimes be declared in that manner.

<ul class="col col-double clearfix">
 <li class="col__item" ng-repeat="location in searchLocations">
   <label>
    <input type="checkbox" ng-click="onLocationSelectionClicked($event)" checklist-model="selectedAuctions.locations" checklist-value="location.code" checklist-change="auctionSelectionChanged()" id="{{location.code}}"> {{location.displayName}}
   </label>



$scope.onLocationSelectionClicked = function($event) {
      if($scope.limitSelectionCountTo &&         $scope.selectedAuctions.locations.length == $scope.limitSelectionCountTo) {
         $event.currentTarget.checked=false;
      }
   };

I can also use

show errors;

In sql worksheet.

This should get you started:

log4j.rootLogger=QuietAppender, LoudAppender, TRACE
# setup A1
log4j.appender.QuietAppender=org.apache.log4j.RollingFileAppender
log4j.appender.QuietAppender.Threshold=INFO
log4j.appender.QuietAppender.File=quiet.log
...


# setup A2
log4j.appender.LoudAppender=org.apache.log4j.RollingFileAppender
log4j.appender.LoudAppender.Threshold=DEBUG

$dateValue = '2012-01-05';
$yeararray = explode("-", $dateValue);

echo "Year : ". $yeararray[0];
echo "Month : ". date( 'F', mktime(0, 0, 0, $yeararray[1]));

Usiong explode() this can be done.

It looks like you want:

public static string GetRandomBits()

Without static, you would need an object before you can call the GetRandomBits() method. However, since the implementation of GetRandomBits() does not depend on the state of any Program object, it's best to declare it static.

Here is another choice: Chaosreader

So I need to debug an application which posts xml to a 3rd party application. I found a brilliant little perl script which does all the hard work – you just chuck it a tcpdump output file, and it does all the manipulation and outputs everything you need...

The script is called chaosreader0.94. See http://www.darknet.org.uk/2007/11/chaosreader-trace-tcpudp-sessions-from-tcpdump/

It worked like a treat, I did the following:

tcpdump host www.blah.com -s 9000 -w outputfile; perl chaosreader0.94 outputfile

I frequently use this, and put everything into a single copy command. The following copies example.txt as example_YYYYMMDD_HHMMSS.txt and of course you can modify it to suit your preferred format. The quotes are only necessary if there are any spaces in the filespec. If you want to reuse the exact same date/timestamp, you'd need to store it in a variable.

copy "{path}\example.txt" "{path}\_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt"

I hit the same problem with "Visual Studio 2013".

LNK1104: cannot open file 'debug\****.exe

It resolved after closing and re-starting Visual studio.

Sometimes if the update application is abruptly stopped, then the lock remains stuck.

Then running

UPDATE DATABASECHANGELOGLOCK SET LOCKED=0, LOCKGRANTED=null, LOCKEDBY=null where ID=1;

against the database helps.

You may also need to replace LOCKED=0 with LOCKED=FALSE.

Or you can simply drop the DATABASECHANGELOGLOCK table, it will be recreated.

If it's giving you errors with gtk, try qt.

sudo apt-get install libqt4-dev
cmake -D WITH_QT=ON ..
make
sudo make install

If this doesn't work, there's an easy way out.

sudo apt-get install libopencv-*

This will download all the required dependencies(although it seems that you have all the required libraries installed, but still you could try it once). This will probably install OpenCV 2.3.1 (Ubuntu 12.04). But since you have OpenCV 2.4.3 in /usr/local/lib include this path in /etc/ld.so.conf and do ldconfig. So now whenever you use OpenCV, you'd use the latest version. This is not the best way to do it but if you're still having problems with qt or gtk, try this once. This should work.

Update - 18th Jun 2019

I got this error on my Ubuntu(18.04.1 LTS) system for openCV 3.4.2, as the method call to cv2.imshow was failing (e.g., at the line of cv2.namedWindow(name) with error: cv2.error: OpenCV(3.4.2). The function is not implemented.). I am using anaconda. Just the below 2 steps helped me resolve:

conda remove opencv
conda install -c conda-forge opencv=4.1.0

If you are using pip, you can try

pip install opencv-contrib-python

If the maximum number of digits in the counter is known (e.g., n = 3 for counters 1..876), you can do

str = "file_" + i.to_s.rjust(n, "0")

let url = URL(string: "URLSTRING HERE")
let anyvar =  String(describing: url)

Use jFeed - a jQuery RSS/Atom plugin. According to the docs, it's as simple as:

jQuery.getFeed({
   url: 'rss.xml',
   success: function(feed) {
      alert(feed.title);
   }
});

For those like @sha1 wondering why the OP's code doesn't work -

OP's logic for deleting player at server side is in the handler for DelPlayer event, and the code that emits this event (DelPlayer) is in inside disconnected event callback of client.

The server side code that emits this disconnected event is inside the disconnect event callback which is fired when the socket loses connection. Since the socket already lost connection, disconnected event doesn't reach the client.

Accepted solution executes the logic on disconnect event at server side, which is fired when the socket disconnects, hence works.

I had the same problem. I already had the '&' and still it was giving the same warning. I'm using PHP 5.3 with WAMP and all i did was REMOVE '&' sign and the warning was gone.

$obj= new stdClass();  //Without '&' sign.

So here's what I found out.

Flush would not work under Apache's mod_gzip or Nginx's gzip because, logically, it is gzipping the content, and to do that it must buffer content to gzip it. Any sort of web server gzipping would affect this. In short, at the server side we need to disable gzip and decrease the fastcgi buffer size. So:

• In php.ini:

  output_buffering = Off
  
  zlib.output_compression = Off
  

• In nginx.conf:

  gzip  off;
  
  proxy_buffering  off;
  

Also have these lines at hand, especially if you don't have access to php.ini:

@ini_set('zlib.output_compression',0);

@ini_set('implicit_flush',1);

@ob_end_clean();

set_time_limit(0);

Last, if you have it, comment the code bellow:

ob_start('ob_gzhandler');

ob_flush();

PHP test code:

ob_implicit_flush(1);

for ($i=0; $i<10; $i++) {
    echo $i;

    // this is to make the buffer achieve the minimum size in order to flush data
    echo str_repeat(' ',1024*64);

    sleep(1);
}

A clustered index actually describes the order in which records are physically stored on the disk, hence the reason you can only have one.

A Non-Clustered Index defines a logical order that does not match the physical order on disk.

Here are two options to emulate the needed behavior. Not a general solution, but may help in some cases. The vertical spacing here is calculated on the basis of the size of the outer element, not its parent, but this size itself can be relative to the parent and this way the spacing will be relative too.

<div id="outer">
    <div id="inner">
        content
    </div>
</div>

First option: use pseudo-elements, here vertical and horizontal spacing are relative to the outer. Demo

#outer::before, #outer::after {
    display: block;
    content: "";
    height: 10%;
}
#inner {
    height: 80%;
    margin-left: 10%;
    margin-right: 10%;
}

Moving the horizontal spacing to the outer element makes it relative to the parent of the outer. Demo

#outer {
    padding-left: 10%;
    padding-right: 10%;
}

Second option: use absolute positioning. Demo

#outer {
    position: relative;
}
#inner {
    position: absolute;
    left: 10%;
    right: 10%;
    top: 10%;
    bottom: 10%;
}

Hopefully, it will work for you.

startActivityForResult( intent, 1 , ActivityOptions.makeCustomAnimation(getActivity(),R.anim.slide_out_bottom,R.anim.slide_in_bottom).toBundle());

I have used this simple and clever way for creating random color in Java,

Random random = new Random();
        System.out.println(String.format("#%06x", random.nextInt(256*256*256)));

Where #%06x gives you zero-padded hex (always 6 characters long).

If you're working on the heroku remote (default):

heroku git:remote -a [app name]

If you want to specify a different remote, use the -r argument:

heroku git:remote -a [app name] -r [remote] 

EDIT: thanks to ??????? ???????? For pointing it out that there's no need to delete the old remote.

I need a list of files that had changed content between two commits (only added or modified), so I used:

git diff --name-only --diff-filter=AM <commit hash #1> <commit hash #2>

The different diff-filter options from the git diff documentation:

diff-filter=[(A|C|D|M|R|T|U|X|B)…?[*]]

Select only files that are Added (A), Copied (C), Deleted (D), Modified (M), Renamed (R), have their type (i.e. regular file, symlink, submodule, …?) changed (T), are Unmerged (U), are Unknown (X), or have had their pairing Broken (B). Any combination of the filter characters (including none) can be used. When * (All-or-none) is added to the combination, all paths are selected if there is any file that matches other criteria in the comparison; if there is no file that matches other criteria, nothing is selected.

Also, these upper-case letters can be downcased to exclude. E.g. --diff-filter=ad excludes added and deleted paths.

If you want to list the status as well (e.g. A / M), change --name-only to --name-status.

Date has before and after methods and can be compared to each other as follows:

if(todayDate.after(historyDate) && todayDate.before(futureDate)) {
    // In between
}

For an inclusive comparison:

if(!historyDate.after(todayDate) && !futureDate.before(todayDate)) {
    /* historyDate <= todayDate <= futureDate */ 
}

You could also give Joda-Time a go, but note that:

Joda-Time is the de facto standard date and time library for Java prior to Java SE 8. Users are now asked to migrate to java.time (JSR-310).

Back-ports are available for Java 6 and 7 as well as Android.

In SQL Developer, from the top menu choose Tools > Data Export. This launches the Data Export wizard. It's pretty straightforward from there.

I've made a library that implements incremental md5 in order to hash large files efficiently. Basically you read a file in chunks (to keep memory low) and hash it incrementally. You got basic usage and examples in the readme.

Be aware that you need HTML5 FileAPI, so be sure to check for it. There is a full example in the test folder.

Other answers here address the general question of what the proper Content-Type for an XML response is, and conclude (as with What's the difference between text/xml vs application/xml for webservice response) that both text/xml and application/xml are permissible. However, none address whether there are any rules specific to sitemaps.

Answer: there aren't. The sitemap spec is https://www.sitemaps.org, and using Google site: searches you can confirm that it does not contain the words or phrases mime, mimetype, content-type, application/xml, or text/xml anywhere. In other words, it is entirely silent on the topic of what Content-Type should be used for serving sitemaps.

In the absence of any commentary in the sitemap spec directly addressing this question, we can safely assume that the same rules apply as when choosing the Content-Type of any other XML document - i.e. that it may be either text/xml or application/xml.

You can call a JavaScript function and use window.location = 'url';:

std::string is the C++ equivalent: It's mutable.

The event.which property normalizes event.keyCode and event.charCode. It is recommended to watch event.which for keyboard key input.

Craigslist does have a "bulk posting interface" which allows for multiple posts to happen at once through HTTPS POST. See:

http://www.craigslist.org/about/bulk_posting_interface

A carriage return (\r) makes the cursor jump to the first column (begin of the line) while the newline (\n) jumps to the next line and eventually to the beginning of that line. So to be sure to be at the first position within the next line one uses both.

<a onclick="window.open(this.href,'_blank');return false;" href="http://www.foracure.org.au">Some Other Site</a>

It makes sense to me.

There's a WebKit-Sharp component on Mono's Subversion Server. I can't find any web-viewable documentation on it, and I'm not even sure if it's WinForms or GTK# (can't grab the source from here to check at the moment), but it's probably your best bet, either way.

I think this component is CLI wrapper around webkit for Ubuntu. So this wrapper most likely could be not working on win32

Try check another variant - project awesomium - wrapper around google project "Chromium" that use webkit. Also awesomium has features like to should interavtive web pages on 3D objects under WPF

An alternative to System.Diagnostics.StackTrace is to use System.Environment.StackTrace which returns a string-representation of the stacktrace.

Another useful option is to use the $CALLER and $CALLSTACK debugging variables in Visual Studio since this can be enabled run-time without rebuilding the application.

Using Node.js you can export the variable via module.

//first.js
const colorCode = {
    black: "#000",
    white: "#fff"
};
module.exports = { colorCode };

Then, import the module/variable in second file using require.

//second.js
const { colorCode } = require('./first.js')

You can use the import and export aproach from ES6 using Webpack/Babel, but in Node.js you need to enable a flag, and uses the .mjs extension.

Yes, it is correct. Its just a helper function to have a simpler way to access your state properties

Imagine you have a posts key in your App state.posts

state.posts //
/*    
{
  currentPostId: "",
  isFetching: false,
  allPosts: {}
}
*/

And component Posts

By default connect()(Posts) will make all state props available for the connected Component

const Posts = ({posts}) => (
  <div>
    {/* access posts.isFetching, access posts.allPosts */}
  </div> 
)

Now when you map the state.posts to your component it gets a bit nicer

const Posts = ({isFetching, allPosts}) => (
  <div>
    {/* access isFetching, allPosts directly */}
  </div> 
)

connect(
  state => state.posts
)(Posts)

mapDispatchToProps

normally you have to write dispatch(anActionCreator())

with bindActionCreators you can do it also more easily like

connect(
  state => state.posts,
  dispatch => bindActionCreators({fetchPosts, deletePost}, dispatch)
)(Posts)

Now you can use it in your Component

const Posts = ({isFetching, allPosts, fetchPosts, deletePost }) => (
  <div>
    <button onClick={() => fetchPosts()} />Fetch posts</button>
    {/* access isFetching, allPosts directly */}
  </div> 
)

Update on actionCreators..

An example of an actionCreator: deletePost

const deletePostAction = (id) => ({
  action: 'DELETE_POST',
  payload: { id },
})

So, bindActionCreators will just take your actions, wrap them into dispatch call. (I didn't read the source code of redux, but the implementation might look something like this:

const bindActionCreators = (actions, dispatch) => {
  return Object.keys(actions).reduce(actionsMap, actionNameInProps => {
    actionsMap[actionNameInProps] = (...args) => dispatch(actions[actionNameInProps].call(null, ...args))
    return actionsMap;
  }, {})
}

You need to write SSIS to copy the table and its data, constraints and triggers. We have in our organization a software called Kal Admin by kalrom Systems that has a free version for downloading (I think that the copy tables feature is optional)

position: absolute will position the element by coordinates, relative to the closest positioned ancestor, i.e. the closest parent which isn't position: static.

Have your four divs nested inside the target div, give the target div position: relative, and use position: absolute on the others.

Structure your HTML similar to this:

<div id="container">
  <div class="top left"></div>
  <div class="top right"></div>
  <div class="bottom left"></div>
  <div class="bottom right"></div>
</div>

And this CSS should work:

#container {
  position: relative;
}

#container > * {
  position: absolute;
}

.left {
  left: 0;
}

.right {
  right: 0;
}

.top {
  top: 0;
}

.bottom {
  bottom: 0;
}

...

Just a word of warnings. I finally got around the problem with Firefox and CORS.

The solution for me was this post

Setting CORS (cross-origin resource sharing) on Apache with correct response headers allowing everything through | Benjamin Horn

However Firefox was behaving really, really strange after setting those headers on the Apache server (in the folder .htaccess).

I added a lot of console.log("Hi FF, you are here A") etc to see what was going on.

At first it looked like it hanged on xhr.send(). But then I discovered it did not get to the this statement. I placed another console.log right before it and did not get there - even though there was nothing between the last console.log and the new one. It just stopped between two console.log.

Reordering lines, deleting, to see if there was any strange character in the file. I found nothing.

Restarting Firefox fixed the trouble.

Yes, I should file a bug. It is just that it is so strange so don't know how to reproduce it.

NOTICE: And, oh, I just did the Header always set parts, not the Rewrite* part!

If you want make a border in a shape xml. You need to use:

For the external border,you need to use:

<stroke/>

For the internal background,you need to use:

<solid/>

If you want to set corners,you need to use:

<corners/>

If you want a padding betwen border and the internal elements,you need to use:

<padding/>

Here is a shape xml example using the above items. It works for me

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="2dp" android:color="#D0CFCC" /> 
  <solid android:color="#F8F7F5" /> 
  <corners android:radius="10dp" />
  <padding android:left="2dp" android:top="2dp" android:right="2dp" android:bottom="2dp" />
</shape>

What is it?

Javascript is a prototypal language which means it uses prototypes for 'inheritance'. the instanceof operator tests if a constructor function's prototype propertype is present in the __proto__ chain of an object. This means that it will do the following (assuming that testObj is a function object):

obj instanceof testObj;

1. Check if prototype of the object is equal to the prototype of the constructor: obj.__proto__ === testObj.prototype >> if this is true instanceof will return true.
2. Will climb up the prototype chain. For example: obj.__proto__.__proto__ === testObj.prototype >> if this is true instanceof will return true.
3. Will repeat step 2 until the full prototype of object is inspected. If nowhere on the prototype chain of the object is matched with testObj.prototype then instanceof operator will return false.

Example:

function Person(name) {_x000D_
  this.name = name;_x000D_
}_x000D_
var me = new Person('Willem');_x000D_
_x000D_
console.log(me instanceof Person); // true_x000D_
// because:  me.__proto__ === Person.prototype  // evaluates true_x000D_
_x000D_
console.log(me instanceof Object); // true_x000D_
// because:  me.__proto__.__proto__ === Object.prototype  // evaluates true_x000D_
_x000D_
console.log(me instanceof Array);  // false_x000D_
// because: Array is nowhere on the prototype chain

What problems does it solve?

It solved the problem of conveniently checking if an object derives from a certain prototype. For example, when a function recieves an object which can have various prototypes. Then, before using methods from the prototype chain, we can use the instanceof operator to check whether the these methods are on the object.

Example:

function Person1 (name) {_x000D_
  this.name = name;_x000D_
}_x000D_
_x000D_
function Person2 (name) {_x000D_
  this.name = name;_x000D_
}_x000D_
_x000D_
Person1.prototype.talkP1 = function () {_x000D_
  console.log('Person 1 talking');_x000D_
}_x000D_
_x000D_
Person2.prototype.talkP2 = function () {_x000D_
  console.log('Person 2 talking');_x000D_
}_x000D_
_x000D_
_x000D_
function talk (person) {_x000D_
  if (person instanceof Person1) {_x000D_
    person.talkP1();_x000D_
  }_x000D_
  _x000D_
  if (person instanceof Person2) {_x000D_
    person.talkP2();_x000D_
  }_x000D_
  _x000D_
  _x000D_
}_x000D_
_x000D_
const pers1 = new Person1 ('p1');_x000D_
const pers2 = new Person2 ('p2');_x000D_
_x000D_
talk(pers1);_x000D_
talk(pers2);

Here in the talk() function first is checked if the prototype is located on the object. After this the appropriate method is picked to execute. Not doing this check could result in executing a method which doesn't exist and thus a reference error.

When is it appropriate and when not?

We kind of already went over this. Use it when you are in need of checking the prototype of an object before doing something with it.

A simple case that generates this error message:

In [8]: [1,2,3,4,5][np.array([1])]
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-8-55def8e1923d> in <module>()
----> 1 [1,2,3,4,5][np.array([1])]

TypeError: only integer scalar arrays can be converted to a scalar index

Some variations that work:

In [9]: [1,2,3,4,5][np.array(1)]     # this is a 0d array index
Out[9]: 2
In [10]: [1,2,3,4,5][np.array([1]).item()]    
Out[10]: 2
In [11]: np.array([1,2,3,4,5])[np.array([1])]
Out[11]: array([2])

Basic python list indexing is more restrictive than numpy's:

In [12]: [1,2,3,4,5][[1]]
....
TypeError: list indices must be integers or slices, not list

edit

Looking again at

indices = np.random.choice(range(len(X_train)), replace=False, size=50000, p=train_probs)

indices is a 1d array of integers - but it certainly isn't scalar. It's an array of 50000 integers. List's cannot be indexed with multiple indices at once, regardless of whether they are in a list or array.

Here's my vb.net port of Matt Johnson's answer. I added an enum for the logon types. LOGON32_LOGON_INTERACTIVE was the first enum value that worked for sql server. My connection string was just trusted. No user name / password in the connection string.

You need to Use with a Using statement to contain some code to run impersonated.

If you don't want to hardcode the domain name, you can use this redirect block. The domain without the leading www is saved as variable $domain which can be reused in the redirect statement.

server {
    ...
    # Redirect www to non-www
    if ( $host ~ ^www\.(?<domain>.+) ) {
       rewrite ^/(.*)$ $scheme://$domain/$1;
    }
}

Use the credential that you use to login to PC. Username can be searched by Clicking in sequence

Advanced -> Find -> Choose your Username -> (e.g. JOHNSMITH_HP/John)

Password must be same as your windows login password

There you go !!

You can use a regex like this to extract normal url patterns.

(https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\.[^\s]{2,}|www\.[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\.[^\s]{2,}|https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9]+\.[^\s]{2,}|www\.[a-zA-Z0-9]+\.[^\s]{2,})

If you need more sophisticated patterns, use a library like this.

https://www.npmjs.com/package/pattern-dreamer

/^[-\w\s]+$/

\w matches letters, digits, and underscores

\s matches spaces, tabs, and line breaks

- matches the hyphen (if you have hyphen in your character set example [a-z], be sure to place the hyphen at the beginning like so [-a-z])

I used pekka's pattern. I think yet another pattern.

<script src="<% = Url.Content("~/Site/Scripts/myjsfile.js") %>?root=<% = Page.ResolveUrl("~/Site/images") %>">

Annoying error. I solved it by plugging the cable directly into the iPad. For some reason the process would never finish if I had the iPad in Apple's pass-through stand.

I'm not sure that the method that you give is really inefficient, but an alternate way, as long as it doesn't have to be flexible in the length or padding character, would be (assuming that you want to pad it with "0" to 10 characters:

DECLARE
   @pad_characters VARCHAR(10)

SET @pad_characters = '0000000000'

SELECT RIGHT(@pad_characters + @str, 10)

If you want to allow 1 and 1.2:

(?<=^| )\d+(\.\d+)?(?=$| )

If you want to allow 1, 1.2 and .1:

(?<=^| )\d+(\.\d+)?(?=$| )|(?<=^| )\.\d+(?=$| )

If you want to only allow 1.2 (only floats):

(?<=^| )\d+\.\d+(?=$| )

\d allows digits (while \D allows anything but digits).

(?<=^| ) checks that the number is preceded by either a space or the beginning of the string. (?=$| ) makes sure the string is followed by a space or the end of the string. This makes sure the number isn't part of another number or in the middle of words or anything.

Edit: added more options, improved the regexes by adding lookahead- and behinds for making sure the numbers are standalone (i.e. aren't in the middle of words or other numbers.

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

Please check "top" command then if your script or any are running please note 'PID'

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

I created a PowerShell advanced function (script cmdlet) a while back that allows you to query multiple computers.

The code for the function is a little over 100 lines long, so you can find it here: PowerShell version of the df command

Check out the Usage section for examples. The following usage example queries a set of remote computers (input from the PowerShell pipeline) and displays the output in a table format with numeric values in human-readable form:

PS> $cred = Get-Credential -Credential 'example\administrator'
PS> 'db01','dc01','sp01' | Get-DiskFree -Credential $cred -Format | Format-Table -GroupBy Name -AutoSize

It's because it's already null or undefined. Null or undefined does not have any type. You can check if it's is undefined first. In typescript (null == undefined) is true.

  if (uemail == undefined) {
      alert('undefined');
  } else {
      alert('defined');
  }

or

  if (uemail == null) {
      alert('undefined');
  } else {
      alert('defined');
  }

I was asking myself this question too, then I came Express 4.x guide page to see this sample:

var server = app.listen(3000, function() {
   console.log('Listening on port %d', server.address().port);
});

Thanks HansUp for your answer, it is very helpful and it works!

I found three patterns working in Access, yours is the best, because it works in all cases.

• INNER JOIN, your variant. I will call it "closed set pattern". It is possible to join more than two tables to the same table with good performance only with this pattern.

  SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
  FROM
       ((class
         INNER JOIN person AS cr 
         ON class.C_P_ClassRep=cr.P_Nr
       )
       INNER JOIN person AS cr2
       ON class.C_P_ClassRep2nd=cr2.P_Nr
    )
  

  ;

• INNER JOIN "chained-set pattern"

  SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
  FROM person AS cr
  INNER JOIN ( class 
     INNER JOIN ( person AS cr2
     ) ON class.C_P_ClassRep2nd=cr2.P_Nr
  ) ON class.C_P_ClassRep=cr.P_Nr
  ;
  

• CROSS JOIN with WHERE

  SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
  FROM class, person AS cr, person AS cr2
  WHERE class.C_P_ClassRep=cr.P_Nr AND class.C_P_ClassRep2nd=cr2.P_Nr
  ;
  

The difference is in the arguments. It's very common to generate a random number from a uniform distribution in the range [0.0, 1.0), so random.random() just does this. Use random.uniform(a, b) to specify a different range.

This is me combining/modifying previous posts to achieve my desired result:

        // Override built-in date validator
        $.validator.addMethod(
            "date",
            function (value, element) {
                //Return            NB: isRequired is not checked at this stage
                return (value=="")? true : isDate(value);
            },
            "* invalid"
        );

Add Date validation after your validation config. I.e. after calling the $(form).validate({ ... }) method.

        //Add date validation (if applicable)
        $('.date', $(frmPanelBtnId)).each(function () {
            $(this).rules('add', {
                date: true
            });
        });

Finally, the main isDate Javascript function modified for UK Date Format

//Validates a date input -- http://jquerybyexample.blogspot.com/2011/12/validate-date-    using-jquery.html
function isDate(txtDate) {
    var currVal = txtDate;
    if (currVal == '')
       return false;

  //Declare Regex  
  var rxDatePattern = /^(\d{1,2})(\/|-)(\d{1,2})(\/|-)(\d{4})$/;
  var dtArray = currVal.match(rxDatePattern); // is format OK?

  if (dtArray == null)
      return false;

   //Checks for dd/mm/yyyy format.
   var dtDay = dtArray[1];
   var dtMonth = dtArray[3];
   var dtYear = dtArray[5];

  if (dtMonth < 1 || dtMonth > 12)
      return false;
  else if (dtDay < 1 || dtDay > 31)
      return false;
  else if ((dtMonth == 4 || dtMonth == 6 || dtMonth == 9 || dtMonth == 11) && dtDay == 31)
      return false;
  else if (dtMonth == 2) {
      var isleap = (dtYear % 4 == 0 && (dtYear % 100 != 0 || dtYear % 400 == 0));
      if (dtDay > 29 || (dtDay == 29 && !isleap))
          return false;
  }

  return true;
}

Html code

<div id="coloredBy">
    Colored By Santa
</div>

javascript code

document.getElementById("coloredBy").style.color = colorCode; // red or #ffffff

I think this is very easy to use

Simply add reference to P1 from P2

The Placeholder does not render any tags for itself, so it is great for grouping content without the overhead of outer HTML tags.

The Panel does have outer HTML tags but does have some cool extra properties.

• BackImageUrl: Gets/Sets the background image's URL for the panel

• HorizontalAlign: Gets/Sets the
  horizontal alignment of the parent's contents

• Wrap: Gets/Sets whether the
  panel's content wraps

There is a good article at startvbnet here.

The answer of @alexandre with base64 does the trick.

The explanation why that works for IE is here

https://en.m.wikipedia.org/wiki/Data_URI_scheme

Under header 'format' where it says

Some browsers (Chrome, Opera, Safari, Firefox) accept a non-standard ordering if both ;base64 and ;charset are supplied, while Internet Explorer requires that the charset's specification must precede the base64 token.

For me, I usually use DataContext together in order to bind two-depth property such as this question.

<TextBlock DataContext="{Binding SelectedRule}" Text="{Binding Name}" />

Or, I prefer to use ElementName because it achieves bindings only with view controls.

<TextBlock DataContext="{Binding ElementName=lbRules, Path=SelectedItem}" Text="{Binding Name}" />

Between Activity: Worked for me

ArrayList<Object> object = new ArrayList<Object>();
Intent intent = new Intent(Current.class, Transfer.class);
Bundle args = new Bundle();
args.putSerializable("ARRAYLIST",(Serializable)object);
intent.putExtra("BUNDLE",args);
startActivity(intent);

In the Transfer.class

Intent intent = getIntent();
Bundle args = intent.getBundleExtra("BUNDLE");
ArrayList<Object> object = (ArrayList<Object>) args.getSerializable("ARRAYLIST");

Hope this help's someone.

Using Parcelable to pass data between Activity

This usually works when you have created DataModel

e.g. Suppose we have a json of type

{
    "bird": [{
        "id": 1,
        "name": "Chicken"
    }, {
        "id": 2,
        "name": "Eagle"
    }]
}

Here bird is a List and it contains two elements so

we will create the models using jsonschema2pojo

Now we have the model class Name BirdModel and Bird BirdModel consist of List of Bird and Bird contains name and id

Go to the bird class and add interface "implements Parcelable"

add implemets method in android studio by Alt+Enter

Note: A dialog box will appear saying Add implements method press Enter

The add Parcelable implementation by pressing the Alt + Enter

Note: A dialog box will appear saying Add Parcelable implementation and Enter again

Now to pass it to the intent.

List<Bird> birds = birdModel.getBird();
Intent intent = new Intent(Current.this, Transfer.class);
Bundle bundle = new Bundle();
bundle.putParcelableArrayList("Birds", birds);
intent.putExtras(bundle);
startActivity(intent);

And on Transfer Activity onCreate

List<Bird> challenge = this.getIntent().getExtras().getParcelableArrayList("Birds");

Thanks

If there is any problem please let me know.
