You can try yourself:

>>> import pandas as pd
>>> from StringIO import StringIO
>>> s = """1, 2
... 3, 4
... 5, 6"""
>>> pd.read_csv(StringIO(s), skiprows=[1], header=None)
   0  1
0  1  2
1  5  6
>>> pd.read_csv(StringIO(s), skiprows=1, header=None)
   0  1
0  3  4
1  5  6

With ASP.NET 5 there is no Request variable available anymore. You can access it now with Context.Request

Also there is no IsAjaxRequest() Method anymore, you have to write it by yourself, for example in Extensions\HttpRequestExtensions.cs

using System;
using Microsoft.AspNetCore.Http;

namespace Microsoft.AspNetCore.Mvc
{
    public static class HttpRequestExtensions
    {
        public static bool IsAjaxRequest(this HttpRequest request)
        {
            if (request == null)
            {
                throw new ArgumentNullException(nameof(request));
            }

            return (request.Headers != null) && (request.Headers["X-Requested-With"] == "XMLHttpRequest");
        }
    }
}

I searched for a while now on this and hope that will help some others too ;)

Following this doc you can do this that way:

{{ p.User['first_name']|default('NONE') }}

I agree with the "simple" solution of listing all the columns, but this can be burdensome, and typos can cause lots of wasted time. I use a function "getTableColumns" to retrieve the names of my columns suitable for pasting into a query. Then all I need to do is to delete those I don't want.

CREATE FUNCTION `getTableColumns`(tablename varchar(100)) 
          RETURNS varchar(5000) CHARSET latin1
BEGIN
  DECLARE done INT DEFAULT 0;
  DECLARE res  VARCHAR(5000) DEFAULT "";

  DECLARE col  VARCHAR(200);
  DECLARE cur1 CURSOR FOR 
    select COLUMN_NAME from information_schema.columns 
    where TABLE_NAME=@table AND TABLE_SCHEMA="yourdatabase" ORDER BY ORDINAL_POSITION;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
  OPEN cur1;
  REPEAT
       FETCH cur1 INTO col;
       IF NOT done THEN 
          set res = CONCAT(res,IF(LENGTH(res)>0,",",""),col);
       END IF;
    UNTIL done END REPEAT;
  CLOSE cur1;
  RETURN res;

Your result returns a comma delimited string, for example...

col1,col2,col3,col4,...col53

This CORS issue wasn't further elaborated (for other causes).

I'm having this issue currently under different reason. My front end is returning 'Access-Control-Allow-Origin' header error as well.

Just that I've pointed the wrong URL so this header wasn't reflected properly (in which i kept presume it did). localhost (front end) -> call to non secured http (supposed to be https), make sure the API end point from front end is pointing to the correct protocol.

The reason you cannot cast List<String> to List<Object> is that it would allow you to violate the constraints of the List<String>.

Think about the following scenario: If I have a List<String>, it is supposed to only contain objects of type String. (Which is a final class)

If I can cast that to a List<Object>, then that allows me to add Object to that list, thus violating the original contract of List<String>.

Thus, in general, if class C inherits from class P, you cannot say that GenericType<C> also inherits from GenericType<P>.

N.B. I already commented on this in a previous answer but wanted to expand on it.

In continuation of the comments by Péter and duncan, I normally use a quick padding method, something like -

public String rpad(String inStr, int finalLength)
{
    return (inStr + "                          " // typically a sufficient length spaces string.
        ).substring(0, finalLength);
}

similarly you can have a lpad() as well

Don't use SSL on port 465, it's been deprecated since 1998 and is only used by Microsoft products that didn't get the memo; use TLS on port 587 instead: So, the code below should work very well for you.

mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "smtp.gmail.com"; // SMTP server

$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "tls";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 587;                   // set the SMTP port for the 

Use DATE() function:

select * from follow_queue group by DATE(follow_date)

TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:
https://git-scm.com/book/en/v2/Git-Branching-Rebasing
(the difference between altering the way version history is recorded)

What's wrong with just invoking the commands?

foo:
       echo line1
       echo line2
       ....

And for your second question, you need to escape the $ by using $$ instead, i.e. bash -c '... echo $$a ...'.

EDIT: Your example could be rewritten to a single line script like this:

gcc $(for i in `find`; do echo $i; done)

There is actually a python library called dataframe_image Just do a

pip install dataframe_image

Do the imports

import pandas as pd
import numpy as np
import dataframe_image as dfi
df = pd.DataFrame(np.random.randn(6, 6), columns=list('ABCDEF'))

and style your table if you want by:

df_styled = df.style.background_gradient() #adding a gradient based on values in cell

and finally:

dfi.export(df_styled,"mytable.png")

I was running into a similar error in pywikipediabot. The .decode method is a step in the right direction but for me it didn't work without adding 'ignore':

ignore_encoding = lambda s: s.decode('utf8', 'ignore')

Ignoring encoding errors can lead to data loss or produce incorrect output. But if you just want to get it done and the details aren't very important this can be a good way to move faster.

Modify onClick() as follows:

@Override
public void onClick(View v) {
    if(v == btn) {
        canvas=sv.getHolder().lockCanvas();
        if(canvas!=null) {
            canvas.drawBitmap(bitmap, 100, 100, null);
            sv.getHolder().unlockCanvasAndPost(canvas);
        }
    } else if(v == btn1) {
        saveBitmapToInternalStorage(bitmap);
    }
}

There are several ways to enforce that btn must be pressed before btn1 so that the bitmap is painted before you attempt to save it.

I suggest that you initially disable btn1, and that you enable it when btn is clicked, like this:

if(v == btn) {
    ...
    btn1.setEnabled(true);
}

the problem is when you do

def __init__(self, user, *args, **kwargs):
    super(waypointForm, self).__init__(*args, **kwargs)
    self.fields['waypoints'] = forms.ChoiceField(choices=[ (o.id, str(o)) for o in Waypoint.objects.filter(user=user)])

in a update request, the previous value will lost!

If it's not working why don't you try using jQuery's scrollTop method?

$("#id").scrollTop($("#id").scrollTop() + 100);

If you're looking to scroll smoothly you could use basic javascript setTimeout/setInterval function to make it scroll in increments of 1px over a set length of time.

This discussion apply both to constructors, but also methods and functions.

Using default parameters?

The good thing is that you won't need to overload constructors/methods/functions for each case:

// Header
void doSomething(int i = 25) ;

// Source
void doSomething(int i)
{
   // Do something with i
}

The bad thing is that you must declare your default in the header, so you have an hidden dependancy: Like when you change the code of an inlined function, if you change the default value in your header, you'll need to recompile all sources using this header to be sure they will use the new default.

If you don't, the sources will still use the old default value.

using overloaded constructors/methods/functions?

The good thing is that if your functions are not inlined, you then control the default value in the source by choosing how one function will behave. For example:

// Header
void doSomething() ;
void doSomething(int i) ;

// Source

void doSomething()
{
   doSomething(25) ;
}

void doSomething(int i)
{
   // Do something with i
}

The problem is that you have to maintain multiple constructors/methods/functions, and their forwardings.

Then click Check SQL server Network Configuration for TCP/IP Enabled

then restart the sql server management studio (SSMS) and connect your local database engine

JSON.NET to the rescue.

You serialize it to JSON to persist in the Database and Deserialize it to reconstitute the .NET collection. This seems to perform better than I expected it to with Entity Framework 6 & SQLite. I know you asked for List<string> but here's an example of an even more complex collection that works just fine.

I tagged the persisted property with [Obsolete] so it would be very obvious to me that "this is not the property you are looking for" in the normal course of coding. The "real" property is tagged with [NotMapped] so Entity framework ignores it.

(unrelated tangent): You could do the same with more complex types but you need to ask yourself did you just make querying that object's properties too hard for yourself? (yes, in my case).

using Newtonsoft.Json;
....
[NotMapped]
public Dictionary<string, string> MetaData { get; set; } = new Dictionary<string, string>();

/// <summary> <see cref="MetaData"/> for database persistence. </summary>
[Obsolete("Only for Persistence by EntityFramework")]
public string MetaDataJsonForDb
{
    get
    {
        return MetaData == null || !MetaData.Any()
                   ? null
                   : JsonConvert.SerializeObject(MetaData);
    }

    set
    {
        if (string.IsNullOrWhiteSpace(value))
           MetaData.Clear();
        else
           MetaData = JsonConvert.DeserializeObject<Dictionary<string, string>>(value);
    }
}

int num = 10;
string str = Convert.ToString(num);

new(): Specifying the new() constraint means type T must use a parameterless constructor, so an object can be instantiated from it - see Default constructors.

class: Means T must be a reference type so it can't be an int, float, double, DateTime or other struct (value type).

public void MakeCars()
{
    //This won't compile as researchEngine doesn't have a public constructor and so can't be instantiated.
    CarFactory<ResearchEngine> researchLine = new CarFactory<ResearchEngine>();
    var researchEngine = researchLine.MakeEngine();

    //Can instantiate new object of class with default public constructor
    CarFactory<ProductionEngine> productionLine = new CarFactory<ProductionEngine>();
    var productionEngine = productionLine.MakeEngine();
}

public class ProductionEngine { }
public class ResearchEngine
{
    private ResearchEngine() { }
}

public class CarFactory<TEngine> where TEngine : class, new()
{
    public TEngine MakeEngine()
    {
        return new TEngine();
    }
}

Try this.

<%@page language="java" session="true" %>

You can add this to your _Layout.cshtml:

@using MyProj.ViewModels;
...
    @if (TempData["UserMessage"] != null)
    {
        var message = (MessageViewModel)TempData["UserMessage"];
        <div class="alert @message.CssClassName" role="alert">
            <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <strong>@message.Title</strong>
            @message.Message
        </div>
    }

Then if you want to throw an error message in your controller:

    TempData["UserMessage"] = new MessageViewModel() { CssClassName = "alert-danger  alert-dismissible", Title = "Error", Message = "This is an error message" };

MessageViewModel.cs:

public class MessageViewModel
    {
        public string CssClassName { get; set; }
        public string Title { get; set; }
        public string Message { get; set; }
    }

A Bcrypt hash can be stored in a BINARY(40) column.

BINARY(60), as the other answers suggest, is the easiest and most natural choice, but if you want to maximize storage efficiency, you can save 20 bytes by losslessly deconstructing the hash. I've documented this more thoroughly on GitHub: https://github.com/ademarre/binary-mcf

Bcrypt hashes follow a structure referred to as modular crypt format (MCF). Binary MCF (BMCF) decodes these textual hash representations to a more compact binary structure. In the case of Bcrypt, the resulting binary hash is 40 bytes.

Gumbo did a nice job of explaining the four components of a Bcrypt MCF hash:

$<id>$<cost>$<salt><digest>

Decoding to BMCF goes like this:

1. $<id>$ can be represented in 3 bits.
2. <cost>$, 04-31, can be represented in 5 bits. Put these together for 1 byte.
3. The 22-character salt is a (non-standard) base-64 representation of 128 bits. Base-64 decoding yields 16 bytes.
4. The 31-character hash digest can be base-64 decoded to 23 bytes.
5. Put it all together for 40 bytes: 1 + 16 + 23

You can read more at the link above, or examine my PHP implementation, also on GitHub.

Here is another solution which uses any/2

map(select(any(.Names[]; contains("data"))|not)|.Id)[]

with the sample data and the -r option it produces

Note: To avoid conflicts between parallel Python 2 and Python 3 installations, only the versioned pip3 and pip3.4 commands are bootstrapped by default when ensurepip is invoked directly - the --default-pip option is needed to also request the unversioned pip command. pyvenv and the Windows installer ensure that the unqualified pip command is made available in those environments, and pip can always be invoked via the -m switch rather than directly to avoid ambiguity on systems with multiple Python installations.

So try pip3 or pip3.4 in Command Prompt.

Also, ensure that environment variable are set for pip command, if you missed to opt-in for automatic PATH configuration.

Since you don't call Num.__init__ , the field "n1" never gets created. Call it and then it will be there.

Another Option that has worked well for me is using the synchronize module . Then remove the original directory using the file module.

Here is an example from the docs:

- synchronize:
    src: /first/absolute/path
    dest: /second/absolute/path
    archive: yes
  delegate_to: "{{ inventory_hostname }}"

I think you need to add some context to your question. However, basic information about these things can be found here:

window.opener https://developer.mozilla.org/en-US/docs/Web/API/Window.opener

I've used window.opener mostly when opening a new window that acted as a dialog which required user input, and needed to pass information back to the main window. However this is restricted by origin policy, so you need to ensure both the content from the dialog and the opener window are loaded from the same origin.

window.parent https://developer.mozilla.org/en-US/docs/Web/API/Window.parent

I've used this mostly when working with IFrames that need to communicate with the window object that contains them.

window.top https://developer.mozilla.org/en-US/docs/Web/API/Window.top

This is useful for ensuring you are interacting with the top level browser window. You can use it for preventing another site from iframing your website, among other things.

If you add some more detail to your question, I can supply other more relevant examples.

UPDATE: There are a few ways you can handle your situation.
You have the following structure:

• Main Window
  • Dialog 1
    • Dialog 2 Opened By Dialog 1

When Dialog 1 runs the code to open Dialog 2, after creating Dialog 2, have dialog 1 set a property on Dialog 2 that references the Dialog1 opener.

So if "childwindow" is you variable for the dialog 2 window object, and "window" is the variable for the Dialog 1 window object. After opening dialog 2, but before closing dialog 1 make an assignment similar to this:

childwindow.appMainWindow = window.opener

After making the assignment above, close dialog 1. Then from the code running inside dialog2, you should be able to use window.appMainWindow to reference the main window, window object.

Hope this helps.

You have to move the css folder into your web folder. It seems that your web folder on the hard drive equals the /ServletApp folder as seen from the www. Other content than inside your web folder cannot be accessed from the browsers.

The url of the CSS link is then

 <link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>

Full description how to use resources: WPF Application Resource, Content, and Data Files

And how to reference them, read "Pack URIs in WPF".

In short, there is even means to reference resources from referenced/referencing assemblies.

So, with customer we create this crazy regex:

(^$)|(^([^\-!#\$%&\(\)\*,\./:;\?@\[\\\]_\{\|\}¨?“”€\+<=>§°\d\s¤®™©]| )+$)

Different Idea:

(1) You save the original file as a variable.

(2) You overwrite the original file with new information.

(3) You append the original file in the data below the new information.

Code:

with open(<filename>,'r') as contents:
      save = contents.read()
with open(<filename>,'w') as contents:
      contents.write(< New Information >)
with open(<filename>,'a') as contents:
      contents.write(save)

Visual Leak Detector (VLD) is a free, robust, open-source memory leak detection system for Visual C++.

When you run your program under the Visual Studio debugger, Visual Leak Detector will output a memory leak report at the end of your debugging session. The leak report includes the full call stack showing how any leaked memory blocks were allocated. Double-click on a line in the call stack to jump to that file and line in the editor window.

If you only have crash dumps, you can use the Windbg !heap -l command, it will detect leaked heap blocks. Better open the gflags option: “Create user mode stack trace database”, then you will see the memory allocation call stack.

For Dense Layers:

output_size * (input_size + 1) == number_parameters 

For Conv Layers:

output_channels * (input_channels * window_size + 1) == number_parameters

Consider following example,

Conv2D(32, (3, 3), activation='relu', input_shape=input_shape),
Conv2D(64, (3, 3), activation='relu'),
Conv2D(128, (3, 3), activation='relu'),
Dense(num_classes, activation='softmax')

So before MySQL 8.0 there is no ROW_NUMBER() function. Accpted answer rewritten to support older versions of MySQL:

SET @row_number = 0;
SELECT t.A, t.B, t.C, (@row_number:=@row_number + 1) AS number
FROM dbo.tableZ AS t ORDER BY t.A;

Your code is doing a log of a number that is less than or equal to zero. That's mathematically undefined, so Python's log function raises an exception. Here's an example:

>>> from math import log
>>> log(-1)
Traceback (most recent call last):
  File "<pyshell#59>", line 1, in <module>
    log(-1)
ValueError: math domain error

Without knowing what your newtonRaphson2 function does, I'm not sure I can guess where the invalid x[2] value is coming from, but hopefully this will lead you on the right track.

You can just compare the boolean array. For example

X = [True, False, True]

then

Y = X == False

would give you

Y = [False, True, False]

Java documentation is helpful to know the root cause of a particular IOException.

Just have a look at the direct known sub-interfaces of IOException from the documentation page:

ChangedCharSetException, CharacterCodingException, CharConversionException, ClosedChannelException, EOFException, FileLockInterruptionException, FileNotFoundException, FilerException, FileSystemException, HttpRetryException, IIOException, InterruptedByTimeoutException, InterruptedIOException, InvalidPropertiesFormatException, JMXProviderException, JMXServerErrorException, MalformedURLException, ObjectStreamException, ProtocolException, RemoteException, SaslException, SocketException, SSLException, SyncFailedException, UnknownHostException, UnknownServiceException, UnsupportedDataTypeException, UnsupportedEncodingException, UserPrincipalNotFoundException, UTFDataFormatException, ZipException

Most of these exceptions are self-explanatory.

A few IOExceptions with root causes:

EOFException: Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal the end of the stream.

SocketException: Thrown to indicate that there is an error creating or accessing a Socket.

RemoteException: A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.

UnknownHostException: Thrown to indicate that the IP address of a host could not be determined (you may not be connected to Internet).

MalformedURLException: Thrown to indicate that a malformed URL has occurred. Either no legal protocol could be found in a specification string or the string could not be parsed.

Closing IIS Express

By default Visual Studio places the IISExpress icon in your system tray at the lower right hand side of your screen, by the clock. You can right click it and choose exit. If you don't see the icon, try clicking the small arrow to view the full list of icons in the system tray.

then right click and choose Exit:

Changing the Port

Another option is to change the port by modifying the project properties. You'll need to do this for each web project in your solution.

1. Visual Studio > Solution Explorer
2. Right click the web project and choose Properties
3. Go to the Web tab
4. In the 'Servers' section, change the port in the Project URL box
5. Repeat for each web project in the solution

If All Else Fails

If that doesn't work, you can try to bring up Task Manager and close the IIS Express System Tray (32 bit) process and IIS Express Worker Process (32 bit).

If it still doesn't work, as ni5ni6 pointed out, there is a 'Web Deployment Agent Service' running on the port 80. Use this article to track down which process uses it, and turn it off:

https://sites.google.com/site/anashkb/port-80-in-use

Question might be a little dated, but you could simply use AbstractMap.SimpleEntry<> as follows:

private Map<String, AttributeType> mapConfig(
    Map<String, String> input, String prefix) {
       int subLength = prefix.length();
       return input.entrySet()
          .stream()
          .map(e -> new AbstractMap.SimpleEntry<>(
               e.getKey().substring(subLength),
               AttributeType.GetByName(e.getValue()))
          .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));

any other Pair-like value object would work too (ie. ApacheCommons Pair tuple).

Once you have markers on the map, you can retrieve the Lat/Long coordinates through the API and use this to set the map's center. You'll first just need to determine which marker you wish to center on - I'll leave that up to you.

// "marker" refers to the Marker object you wish to center on

var latLng = marker.getPosition(); // returns LatLng object
map.setCenter(latLng); // setCenter takes a LatLng object

Info windows are separate objects which are typically bound to a marker, so to open the info window you might do something like this (however it will depend on your code):

var infoWindow = marker.infoWindow; // retrieve the InfoWindow object
infoWindow.open(map); // Trigger the "open()" method

Hope this helps.

what does this error mean? Object reference not set to an instance of an object.

exactly what it says, you are trying to use a null object as if it was a properly referenced object.

The functions^* quit(), exit(), and sys.exit() function in the same way: they raise the SystemExit exception. So there is no real difference, except that sys.exit() is always available but exit() and quit() are only available if the site module is imported.

The os._exit() function is special, it exits immediately without calling any cleanup functions (it doesn't flush buffers, for example). This is designed for highly specialized use cases... basically, only in the child after an os.fork() call.

Conclusion

• Use exit() or quit() in the REPL.

• Use sys.exit() in scripts, or raise SystemExit() if you prefer.

• Use os._exit() for child processes to exit after a call to os.fork().

All of these can be called without arguments, or you can specify the exit status, e.g., exit(1) or raise SystemExit(1) to exit with status 1. Note that portable programs are limited to exit status codes in the range 0-255, if you raise SystemExit(256) on many systems this will get truncated and your process will actually exit with status 0.

Footnotes

^* Actually, quit() and exit() are callable instance objects, but I think it's okay to call them functions.

Old question, but %l (lower-case L) worked for me in strftime: this may not work for everyone, though, as it's not listed in the Python documentation I found

For me, the error message said I had too many simulator files open to build Swift. When I quit the simulator and built again, everything worked.

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
    startActivity(intent);

A filter argument with a trailing * can be evaluated almost instantaneously via an index lookup. A leading * implies a sequential search through the index, so it is O(N). It will take ages.

I suggest you reconsider the requirement.

Although JS implementations might keep track of such a value internally, there's no standard way to get it.

In the past, Mozilla's Javascript variant exposed the non-standard __count__, but it has been removed with version 1.8.5.

For cross-browser scripting you're stuck with explicitly iterating over the properties and checking hasOwnProperty():

function countProperties(obj) {
    var count = 0;

    for(var prop in obj) {
        if(obj.hasOwnProperty(prop))
            ++count;
    }

    return count;
}

In case of ECMAScript 5 capable implementations, this can also be written as (Kudos to Avi Flax)

function countProperties(obj) {
    return Object.keys(obj).length;
}

Keep in mind that you'll also miss properties which aren't enumerable (eg an array's length).

If you're using a framework like jQuery, Prototype, Mootools, $whatever-the-newest-hype, check if they come with their own collections API, which might be a better solution to your problem than using native JS objects.

Probably because the original version of Python (CPython) was written in C, not C++.

The idea that a list is formed by pushing things onto the back of something is probably not as well-known as the thought of appending them.

You can open the file using the ios::ate flag (and ios::binary flag), so the tellg() function will give you directly the file size:

ifstream file( "example.txt", ios::binary | ios::ate);
return file.tellg();

You can also define case insensitive during the pattern compile:

pattern = re.compile('FIle:/+(.*)', re.IGNORECASE)

At first generate Plain Old Java Objects from JSON http://www.jsonschema2pojo.org/

Main method

void createDb(String dbName, String tableName, List dataList, Field[] fields){ ...

Fields name will create dynamically

1. User.destroy

User.destroy(1) will delete user with id == 1 and :before_destroy and :after_destroy callbacks occur. For example if you have associated records

has_many :addresses, :dependent => :destroy

After user is destroyed his addresses will be destroyed too. If you use delete action instead, callbacks will not occur.

2. User.destroy, User.delete

3. User.destroy_all(<conditions>) or User.delete_all(<conditions>)

Notice: User is a class and user is an instance object

From - JQuery_Core_Style_Guidelines

• Global Variables:
  typeof variable === "undefined"

• Local Variables:
  variable === undefined

• Properties:
  object.prop === undefined

A simple semantic name would be last. This would allow code always positive code like:

if (item.last)
    ...

do {
   ...
} until (item.last);

If you happen to be using a mac keyboard on linux (ubuntu), Insert is actually fn + return. You can also click on the zero of the number pad to switch between the cursor types.

Took me a while to figure that out. :-P

I solved the issue in Ubuntu 20.0.4 by

sudo chmod 666 /var/run/docker.sock

and then

sudo service docker start && docker-compose up -d

Hint: actively refused sounds like somewhat deeper technical trouble, but...

...actually, this response (and also specifically errno:10061) is also given, if one calls the bin/mongo executable and the mongodb service is simply not running on the target machine. This even applies to local machine instances (all happening on localhost).

You can simply go Netbeans, in the design view, go to JFrame property, choose icon image property, Choose Set Form's iconImage property using: "Custom code" and then in the Form.SetIconImage() function put the following code:

Toolkit.getDefaultToolkit().getImage(name_of_your_JFrame.class.getResource("image.png"))

Do not forget to import:

import java.awt.Toolkit;

in the source code!

Like

.classname

 opacity: 0.5;
}

You can change axis text and label size with arguments axis.text= and axis.title= in function theme(). If you need, for example, change only x axis title size, then use axis.title.x=.

g+theme(axis.text=element_text(size=12),
        axis.title=element_text(size=14,face="bold"))

There is good examples about setting of different theme() parameters in ggplot2 page.

I exactly agree with @deceze but I want to develop this "I get an error from the service" part of the question,

We getting this kind of errors as http 415

Http 415 Unsupported Media type error

The HTTP 415 Unsupported Media Type client error response code indicates that the server refuses to accept the request because the payload format is in an unsupported format.

The format problem might be due to the request's indicated Content-Type or Content-Encoding, or as a result of inspecting the data directly.

In other words, such is seen in this example.

• We have to set the correct content type and we have to accept the right content type as seen Add Content-Type: application/json and Accept: application/json. Otherwise, it will assume the default

<body>
    <input type="button" value="Increase" id="inc" onclick="incNumber()"/>
    <input type="button" value="Decrease" id="dec" onclick="decNumber()"/>

    <label id="display"></label>

    <script type="text/javascript">

    var i = 0;

    function incNumber() {
        if (i < 10) {
            i++;
        } else if (i = 10) {
            i = 0;
        }
        document.getElementById("display").innerHTML = i;
    }

    function decNumber() {
        if (i > 0) {
            --i;
        } else if (i = 0) {
            i = 10;
        }
        document.getElementById("display").innerHTML = i;
    }
    </script>
</body>

You can use below concept to implement AutoComplete='false' for chrome as well as others browser.

I think there are problems with most of these, including the accepted answer, because they don't work well with Linq over IQueryable either due to doing too many server round trips and too much data returns, or doing too much client execution.

For IEnumerable I don't like Sehe's answer or similar because it has excessive memory use (a simple 10000000 two list test ran Linqpad out of memory on my 32GB machine).

Also, most of the others don't actually implement a proper Full Outer Join because they are using a Union with a Right Join instead of Concat with a Right Anti Semi Join, which not only eliminates the duplicate inner join rows from the result, but any proper duplicates that existed originally in the left or right data.

So here are my extensions that handle all of these issues, generate SQL as well as implementing the join in LINQ to SQL directly, executing on the server, and is faster and with less memory than others on Enumerables:

The difference between a Right Anti-Semi-Join is mostly moot with Linq to Objects or in the source, but makes a difference on the server (SQL) side in the final answer, removing an unnecessary JOIN.

The hand coding of Expression to handle merging an Expression<Func<>> into a lambda could be improved with LinqKit, but it would be nice if the language/compiler had added some help for that. The FullOuterJoinDistinct and RightOuterJoin functions are included for completeness, but I did not re-implement FullOuterGroupJoin yet.

I wrote another version of a full outer join for IEnumerable for cases where the key is orderable, which is about 50% faster than combining the left outer join with the right anti semi join, at least on small collections. It goes through each collection after sorting just once.

I also added another answer for a version that works with EF by replacing the Invoke with a custom expansion.

Adding to the other answers, in a Series there are also map and apply.

Apply can make a DataFrame out of a series; however, map will just put a series in every cell of another series, which is probably not what you want.

In [40]: p=pd.Series([1,2,3])
In [41]: p
Out[31]:
0    1
1    2
2    3
dtype: int64

In [42]: p.apply(lambda x: pd.Series([x, x]))
Out[42]: 
   0  1
0  1  1
1  2  2
2  3  3

In [43]: p.map(lambda x: pd.Series([x, x]))
Out[43]: 
0    0    1
1    1
dtype: int64
1    0    2
1    2
dtype: int64
2    0    3
1    3
dtype: int64
dtype: object

Also if I had a function with side effects, such as "connect to a web server", I'd probably use apply just for the sake of clarity.

series.apply(download_file_for_every_element) 

Map can use not only a function, but also a dictionary or another series. Let's say you want to manipulate permutations.

Take

1 2 3 4 5
2 1 4 5 3

The square of this permutation is

1 2 3 4 5
1 2 5 3 4

You can compute it using map. Not sure if self-application is documented, but it works in 0.15.1.

In [39]: p=pd.Series([1,0,3,4,2])

In [40]: p.map(p)
Out[40]: 
0    0
1    1
2    4
3    2
4    3
dtype: int64

npm install bootstrap --save

and add relevent files into angular.json file under the style property for css files and under scripts for JS files.

 "styles": [
  "../node_modules/bootstrap/dist/css/bootstrap.min.css",
   ....
]

OK, so I don't really know what the problem was, but I simply fixed it by navigating to here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and installing 8u74 instead of 8u73 which is what I was prompted to do when I would go to "download latest version" in Java. So changing the versions is what did it in the end. Eclipse launched fine, now. Thanks for everyone's help!

edit: Apr 2018- Now is 8u161 and 8u162 (Just need one, I used 8u162 and it worked.)

I wrote more universal solution based on @Fer answer.

It also should work with flavor and build type based configuration of applicationId, versionName, versionCode.

In the build.gradle:

android {
    ...
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            def appId = variant.applicationId
            def versionName = variant.versionName
            def versionCode = variant.versionCode
            def flavorName = variant.flavorName // e. g. free
            def buildType = variant.buildType // e. g. debug
            def variantName = variant.name // e. g. freeDebug

            def apkName = appId + '_' + variantName + '_' + versionName + '_' + versionCode + '.apk';
            output.outputFile = new File(output.outputFile.parentFile, apkName)
        }
    }
}

Example apk name: com.example.app_freeDebug_1.0_1.apk

For more information about variant variable see ApkVariant and BaseVariant interfaces definition.

EDIT: URIUtil is no longer available in more recent versions, better answer at Java - encode URL or by Mr. Sindi in this thread.

URIUtil of Apache httpclient is really useful, although there are some alternatives

URIUtil.encodeQuery(url);

For example, it encodes space as "+" instead of "%20"

Both are perfectly valid in the right context. Although if you really preferred you could issue a string replace.

Timothy Pirez answer was very correct but if you need to replace the numbers with commas Immediately as user types in textfield, u might want to use the Keyup function.

      $('#textfield').live('keyup', function (event) {
        var value=$('#textfield').val();

      if(event.which >= 37 && event.which <= 40){
          event.preventDefault();
      }
      var newvalue=value.replace(/,/g, '');   
      var valuewithcomma=Number(newvalue).toLocaleString('en');   
      $('#textfield').val(valuewithcomma); 

      });

    <form><input type="text" id="textfield" ></form>

I am not 100% certain, but I think this does what you want using prop.table. See mostly the last 3 lines. The rest of the code is just creating fake data.

set.seed(1234)

total_bill <- rnorm(50, 25, 3)
tip <- 0.15 * total_bill + rnorm(50, 0, 1)
sex <- rbinom(50, 1, 0.5)
smoker <- rbinom(50, 1, 0.3)
day <- ceiling(runif(50, 0,7))
time <- ceiling(runif(50, 0,3))
size <- 1 + rpois(50, 2)
my.data <- as.data.frame(cbind(total_bill, tip, sex, smoker, day, time, size))
my.data

my.table <- table(my.data$smoker)

my.prop <- prop.table(my.table)

cbind(my.table, my.prop)

To see how much space each container's log is taking up, use this:

docker ps -qa | xargs docker inspect --format='{{.LogPath}}' | xargs ls -hl

(you might need a sudo before ls).

For anyone attempting to compile code from an external source that uses an automated build utility such as Make, to avoid having to track down the explicit gcc compilation calls you can set an environment variable. Enter on command prompt or put in .bashrc (or .bash_profile on Mac):

export CFLAGS="-std=c99"

Note that a similar solution applies if you run into a similar scenario with C++ compilation that requires C++ 11, you can use:

export CXXFLAGS="-std=c++11"

In Python 2:

data = raw_input('Enter something: ')
print data

In Python 3:

data = input('Enter something: ')
print(data)

I have the same question as the original poster, Michael.

However I have tried to apply the answers submitted for the original code without success

After some trial and error, here is my version of the code that works (or at least works for me!). And if you look closely, you will note that it is different to the earlier solutions posted.

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

struct arg_struct
{
   int arg1;
   int arg2;
} *args;

void *print_the_arguments(void *arguments)
{
   struct arg_struct *args = arguments;
   printf("Thread\n");
   printf("%d\n", args->arg1);
   printf("%d\n", args->arg2);
   pthread_exit(NULL);
   return NULL;
}

int main()
{
   pthread_t some_thread;
   args = malloc(sizeof(struct arg_struct) * 1);

   args->arg1 = 5;
   args->arg2 = 7;

   printf("Before\n");
   printf("%d\n", args->arg1);
   printf("%d\n", args->arg2);
   printf("\n");


   if (pthread_create(&some_thread, NULL, &print_the_arguments, args) != 0)
   {
      printf("Uh-oh!\n");
      return -1;
   }

   return pthread_join(some_thread, NULL); /* Wait until thread is finished */
}

Pandas DataFrame object should be thought of as a Series of Series. In other words, you should think of it in terms of columns. The reason why this is important is because when you use pd.DataFrame.iterrows you are iterating through rows as Series. But these are not the Series that the data frame is storing and so they are new Series that are created for you while you iterate. That implies that when you attempt to assign tho them, those edits won't end up reflected in the original data frame.

Ok, now that that is out of the way: What do we do?

Suggestions prior to this post include:

1. pd.DataFrame.set_value is deprecated as of Pandas version 0.21
2. pd.DataFrame.ix is deprecated
3. pd.DataFrame.loc is fine but can work on array indexers and you can do better

My recommendation
Use pd.DataFrame.at

for i in df.index:
    if <something>:
        df.at[i, 'ifor'] = x
    else:
        df.at[i, 'ifor'] = y

You can even change this to:

for i in df.index:
    df.at[i, 'ifor'] = x if <something> else y

Response to comment

and what if I need to use the value of the previous row for the if condition?

for i in range(1, len(df) + 1):
    j = df.columns.get_loc('ifor')
    if <something>:
        df.iat[i - 1, j] = x
    else:
        df.iat[i - 1, j] = y

You should be able to simply let PIL get the filetype from extension, i.e. use:

j.save("C:/Users/User/Desktop/mesh_trans.bmp")

This can be caused when upstream rewrites history.

When this happens, I toss all affected repos, clone them fresh from upstream, and use 'git format-patch' / 'git am' to ferry any work in progress from old world to new.

There is this possibility like Aman Virk mentioned:

var options = {
    chartArea:{left:10,top:20,width:"100%",height:"100%"}
};

But keep in mind that the padding and margin aren't there to bother you. If you have the possibility to switch between different types of charts like a ColumnChart and the one with vertical columns then you need some margin for displaying the labels of those lines.

If you take away that margin then you will end up showing only a part of the labels or no labels at all.

So if you just have one chart type then you can change the margin and padding like Arman said. But if it's possible to switch don't change them.

My grep-a-like program ack has a -1 option that stops at the first match found anywhere. It supports the -m 1 that @mvp refers to as well. I put it in there because if I'm searching a big tree of source code to find something that I know exists in only one file, it's unnecessary to find it and have to hit Ctrl-C.

In python3 with virtualenv on a Ubuntu Bionic machine the following commands worked for me:

sudo apt install build-essential python-dev libmysqlclient-dev
sudo apt-get install libssl-dev
pip install mysqlclient

Regex regex = new Regex("%download#(\\d+?)%", RegexOptions.SingleLine);
Matches m = regex.Matches(input);

I think will do the trick (not tested).

As an alternative, you might use a 9 patch image as the background for your layout, allowing for more "natural" shadows:

Result:

Put the image in your /res/drawable folder.
Make sure the file extension is .9.png, not .png

By the way, this is a modified (reduced to the minimum square size) of an existing resource found in the API 19 sdk resources folder.
I left the red markers, since they don't seem to be harmful, as shown in the draw9patch tool.

[EDIT]

About 9 patches, in case you never had anything to do with them.

Simply add it as the background of your View.

The black-marked areas (left and top) will stretch (vertically, horizontally).
The black-marked areas (right, bottom) define the "content area" (where it's possible to add text or Views - you can call the unmarked regions "padding", if you like to).

Tutorial: http://radleymarx.com/blog/simple-guide-to-9-patch/

A new byte array will automatically be initialized with all zeroes. You don't have to do anything.

The more general approach to initializing with other values, is to use the Arrays class.

import java.util.Arrays;

byte[] bytes = new byte[100];
Arrays.fill( bytes, (byte) 1 );

A better JQuery answer would be:

$('#ParentContainer').scroll(function() { 
    $('#FixedDiv').animate({top:$(this).scrollTop()});
});

You can also add a number after scrollTop i.e .scrollTop() + 5 to give it buff.

A good suggestion would also to limit the duration to 100 and go from default swing to linear easing.

$('#ParentContainer').scroll(function() { 
    $('#FixedDiv').animate({top:$(this).scrollTop()},100,"linear");
})

function toggling_fields_contact_bank(class_name) {
    jQuery("." + class_name).animate({
        height: 'toggle'
    });
}

If you have cloned your project from git or somewhere then first, you should type npm install.

Telerik also has a combo box control. Essentially, it's a textbox with images that when you click on them reveal a panel with a list of predefined options.

http://demos.telerik.com/aspnet-ajax/combobox/examples/overview/defaultcs.aspx

But this is AJAX, so it may have a larger footprint than you want on your website (since you say it's "HTML").

Here are the functions I used for this end:

function localToGMTStingTime(localTime = null) {
    var date = localTime ? new Date(localTime) : new Date();
    return new Date(date.getTime() + (date.getTimezoneOffset() * 60000)).toISOString();
};

function GMTToLocalStingTime(GMTTime = null) {
    var date = GMTTime ? new Date(GMTTime) : new Date();;
    return new Date(date.getTime() - (date.getTimezoneOffset() * 60000)).toISOString();
};

You should need to convert your PHP array to javascript array using PHP syntax json_encode. json_encode convert PHP array to JSON string

Single Dimension PHP array to javascript array

<?php
var $itemsarray= array("Apple", "Bear", "Cat", "Dog");
?>
<script>
var items= <?php echo json_encode($itemsarray); ?>;
console.log(items[2]); // Output: Bear
// OR
alert(items[0]); // Output: Apple
</script>

Multi Dimension PHP array to javascript array

<?php
var $itemsarray= array( 
               array('name'='Apple', 'price'=>'12345'),
               array('name'='Bear', 'price'=>'13344'),
               array('name'='Potato', 'price'=>'00440')
             );
?>


<script>
var items= <?php echo json_encode($itemsarray); ?>;
console.log(items[1][name]); // Output: Bear
// OR
alert(items[0][price]); // Output: Apple
</script>

For more detail, you can also check php array to javascript array

I just had this same problem, and I ended up finding the simplest solution which works for my needs. In the table properties, I set the default value to 0 for the fields that I don't want to show nulls. Super easy.

I got this error when I was trying to write a javascript bookmarklet. I couldn't figure out what was causing it. But eventually I tried URL encoding the bookmarklet, via the following website: http://mrcoles.com/bookmarklet/ and then the error went away, so it must have been a problem with certain characters in the javascript code being interpreted as special URL control characters.

very simple just add this to your bound field DataFormatString="{0: yyyy/MM/dd}"

The most common reasons for me are so that:

1. The layout can have a fixed width (yes, I know, I do a lot of work for designers who love fixed widths), and
2. So the layout can be centered by applying text-align: center to the body and then margin: auto to the left and right of the container div.

Default behavior in numpy is add componentwise

import numpy as np
np.add(first, second)

which outputs

array([7,9,11,13,15])

It is kind of a workaround but works like a charm. Just add <option value="" style="display: none"></option> as a filler. Like in:

<select size="4" ng-model="feed.config" ng-options="template.value as template.name for template in feed.configs">
       <option value="" style="display: none"></option>
</select>

After messing with this for days, my final fix for our issues required two things;

1) We added this line of code to all of our .Net libraries that make out bound api calls to other vendors that had also disabled their SSL v3.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls; // (.Net 4 and below)

2) This is the final and FULL registry changes you will need when you are running ASP.Net 4.0 sites and will need to be slightly changed after you upgrade to ASP.Net 4.5.

After we rebooted the servers - all problems went away after this.

    with open(csv_filename) as file:
        data = file.read()

    with open(xl_file_name, 'w') as file:
        file.write(data)

You can turn CSV to excel like above with inbuilt packages. CSV can be handled with an inbuilt package of dictreader and dictwriter which will work the same way as python dictionary works. which makes it a ton easy I am currently unaware of any inbuilt packages for excel but I had come across openpyxl. It was also pretty straight forward and simple You can see the code snippet below hope this helps

    import openpyxl
    book = openpyxl.load_workbook(filename)
    sheet = book.active 
    result =sheet['AP2']
    print(result.value)

Complete example below. I just love the copy/paste :)

The following (C# implementation, but similar in Java) allows you to determine if there is an alert without exceptions and without creating the WebDriverWait object.

boolean isDialogPresent(WebDriver driver) {
    IAlert alert = ExpectedConditions.AlertIsPresent().Invoke(driver);
    return (alert != null);
}

To first force HTTPS, you must check the correct environment variable %{HTTPS} off, but your rule above then prepends the www. Since you have a second rule to enforce www., don't use it in the first rule.

RewriteEngine On
RewriteCond %{HTTPS} off
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
# [NC] is a case-insensitive match
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

About proxying

When behind some forms of proxying, whereby the client is connecting via HTTPS to a proxy, load balancer, Passenger application, etc., the %{HTTPS} variable may never be on and cause a rewrite loop. This is because your application is actually receiving plain HTTP traffic even though the client and the proxy/load balancer are using HTTPS. In these cases, check the X-Forwarded-Proto header instead of the %{HTTPS} variable. This answer shows the appropriate process

Try this snippet of code:

String timeSettings = android.provider.Settings.System.getString(
                this.getContentResolver(),
                android.provider.Settings.System.AUTO_TIME);
        if (timeSettings.contentEquals("0")) {
            android.provider.Settings.System.putString(
                    this.getContentResolver(),
                    android.provider.Settings.System.AUTO_TIME, "1");
        }
        Date now = new Date(System.currentTimeMillis());
        Log.d("Date", now.toString());

Make sure to add permission in Manifest

<uses-permission android:name="android.permission.WRITE_SETTINGS"/>

I don't like my switch statements to fall through - it's far too error prone and hard to read. The only exception is when multiple case statements all do exactly the same thing.

If there is some common code that multiple branches of a switch statement want to use, I extract that into a separate common function that can be called in any branch.

UPDATE NGRX4

If you are migrating to NGRX 4, you may have noticed from the migration guide that the rootreducer method for combining your reducers has been replaced with ActionReducerMap method. At first, this new way of doing things might make resetting state a challenge. It is actually straight-forward, yet the way of doing this has changed.

This solution is inspired by the meta-reducers API section of the NGRX4 Github docs.

First, lets say your are combining your reducers like this using NGRX's new ActionReducerMap option:

//index.reducer.ts
export const reducers: ActionReducerMap<State> = {
    auth: fromAuth.reducer,
    layout: fromLayout.reducer,
    users: fromUsers.reducer,
    networks: fromNetworks.reducer,
    routingDisplay: fromRoutingDisplay.reducer,
    routing: fromRouting.reducer,
    routes: fromRoutes.reducer,
    routesFilter: fromRoutesFilter.reducer,
    params: fromParams.reducer
}

Now, lets say you want to reset state from within app.module `

//app.module.ts
import { IndexReducer } from './index.reducer';
import { StoreModule, ActionReducer, MetaReducer } from '@ngrx/store';
...
export function debug(reducer: ActionReducer<any>): ActionReducer<any> {
    return function(state, action) {

      switch (action.type) {
          case fromAuth.LOGOUT:
            console.log("logout action");
            state = undefined;
      }

      return reducer(state, action);
    }
  }

  export const metaReducers: MetaReducer<any>[] = [debug];

  @NgModule({
    imports: [
        ...
        StoreModule.forRoot(reducers, { metaReducers}),
        ...
    ]
})

export class AppModule { }

`

And that is basically one way to achieve the same affect with NGRX 4.

If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:

var data = context.MyEntities.AsNoTracking().Where(...).ToList();

As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.

Just for information, the below

window.open("data:application/pdf," + encodeURI(pdfString)); 

does not work anymore in Chrome. Yesterday, I came across with the same issue and tried this solution, but did not work (it is 'Not allowed to navigate top frame to data URL'). You cannot open the data URL directly in a new window anymore. But, you can wrap it in iframe and make it open in a new window like below. =)

let pdfWindow = window.open("")
pdfWindow.document.write(
    "<iframe width='100%' height='100%' src='data:application/pdf;base64, " +
    encodeURI(yourDocumentBase64VarHere) + "'></iframe>"
)

in addition to the options shown in your question, there is the possibility of implementing the action directly in your xml file from the menu, for example:

<item
   android:id="@+id/OK_MENU_ITEM"
   android:onClick="showMsgDirectMenuXml" />

And for your Java (Activity) file, you need to implement a public method with a single parameter of type MenuItem, for example:

 private void showMsgDirectMenuXml(MenuItem item) {
    Toast toast = Toast.makeText(this, "OK", Toast.LENGTH_LONG);
    toast.show();
  }

NOTE: This method will have behavior similar to the onOptionsItemSelected (MenuItem item)

You can call setScale(newScale, roundingMode) method three times with changing the newScale value from 4 to 3 to 2 like

First case

    BigDecimal a = new BigDecimal("10.12345");

    a = a.setScale(4, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.1235
    a = a.setScale(3, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.124
    a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println("" + a); //10.12

Second case

    BigDecimal a = new BigDecimal("10.12556");

    a = a.setScale(4, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.1256
    a = a.setScale(3, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.126
    a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println("" + a); //10.13

I wrote this snippet, that I've been using for handling this exact case.

It's in plain javascript, making it also suitable in cases like with bootsrap5 without jQuery.

<script type='text/javascript'>
    window.onhashchange=hashTriggerTab;
    window.onload=hashTriggerTab;
    
    function hashTriggerTab(){
        var current_hash=window.location.hash;
        if(current_hash.substring(0,1)=='#')current_hash=current_hash.substring(1);
        if(current_hash!=''){
            var trigger=document.querySelector('.nav-tabs a[href="#'+current_hash+'"]');
            if(trigger)trigger.click();
        }
    }
</script>

With that in place, you could link both on the same page, like:

<a href='#tabId'>Link Any Tab</a>

Or from external page like:

<a href='newpage.php#tabId'>Link From External</a>

You can get the user's WindowsIdentity object under Windows Authentication by:

WindowsIdentity identity = HttpContext.Current.Request.LogonUserIdentity;

and then you can get the information about the user like identity.Name.

Please note you need to have HttpContext for these code.

Date.parse supports the format mm/dd/yyyy not dd/mm/yyyy. For the latter, either use a library like moment.js or do something as shown below

var dateFrom = "02/05/2013";
var dateTo = "02/09/2013";
var dateCheck = "02/07/2013";

var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");

var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]);  // -1 because months are from 0 to 11
var to   = new Date(d2[2], parseInt(d2[1])-1, d2[0]);
var check = new Date(c[2], parseInt(c[1])-1, c[0]);

console.log(check > from && check < to)

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

This looks like a homework question, so I'll just give you a few pointers:

Try to give good distinctive variable names. Here you used "fileName" first for the directory, and then for the file. That is confusing, and won't help you solve the problem. Use different names for different things.

You're not using Scanner for anything, and it's not needed here, get rid of it.

Furthermore, the accept method should return a boolean value. Right now, you are trying to return a String. Boolean means that it should either return true or false. For example return a > 0; may return true or false, depending on the value of a. But return fileName; will just return the value of fileName, which is a String.

It's simple enough with the powerful urllib3 library.

Import it like this:

import urllib3

http = urllib3.PoolManager()

And make a request like this:

response = http.request('GET', 'https://example.com')

print(response.data) # Raw data.
print(response.data.decode('utf-8')) # Text.
print(response.status) # Status code.
print(response.headers['Content-Type']) # Content type.

You can add headers too:

response = http.request('GET', 'https://example.com', headers={
    'key1': 'value1',
    'key2': 'value2'
})

More info can be found on the urllib3 documentation.

urllib3 is much safer and easier to use than the builtin urllib.request or http modules and is stable.

It's actually pretty easy. (If you're using Angular 2+ anyway.)

Simply add

declare var myGlobalVarName;

Somewhere in the top of your component file (such as after the "import" statements), and you'll be able to access "myGlobalVarName" anywhere inside your component.

Specifically for Windows users, using curl-7.57.0-win64-mingw or similar version.

This is a bit late, and the existing answers are correct. But I still had to struggle a bit to get it working on my Windows machine, though the process is actually pretty straight forward. So, sharing the step-by-step process.

This error basically means, curl is failing to verify the certificate of the target URI. If you trust the issuer of the certificate (CA), you can add that to the list of trusted certificates.

For that, browse the URI (e.g. on Chrome) and follow the steps

1. Right click on the secure padlock icon
2. Click on certificate, it'll open a window with the certificate details
3. Go to 'Certification Path' tab
4. Click the ROOT certificate
5. Click View Certificate, it'll open another certificate window
6. Go to Details tab
7. Click Copy to File, it'll open the export wizard
8. Click Next
9. Select 'Base-64 encoded X.509 (.CER)'
10. Click Next
11. Give a friendly name e.g. 'MyDomainX.cer' (browse to desired directory)
12. Click Next
13. Click Finish, it'll save the certificate file
14. Now open this .cer file and copy the contents (including -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----)
15. Now go to the directory where curl.exe is saved e.g. C:\SomeFolder\curl-7.57.0-win64-mingw\bin
16. Open the curl-ca-bundle.crt file with a text editor
17. Append the copied certificate text to the end of the file. Save

Now your command should execute fine in curl.

 var myEle = document.getElementById("myElement");
    if(myEle){
        var myEleValue= myEle.value;
    }

the return of getElementById is null if an element is not actually present inside the dom, so your if statement will fail, because null is considered a false value

First note that

Mage::getBaseDir('skin')

returns only path to skin directory of your Magento install (/your/magento/dir/skin).

You can access absolute path to currently used skin directory using:

Mage::getDesign()->getSkinBaseDir()

This method accepts an associative array as optional parameter to modify result.

Following keys are recognized:

• _area frontend (default) or adminhtml
• _package your package
• _theme your theme
• _relative when this is set (as an key) path relative to Mage::getBaseDir('skin') is returned.

So in your case correct answer would be:

require(Mage::getDesign()->getSkinBaseDir().DS.'myfunc.php');

There is another preety interesting site with tts engines that can be used in this manner.

@Steve Farthing's answer is absolutely right.

But if you rotate more than 4 times then the image will get cropped from both the side. For that you need to do like this.

$("#clockwise").click(function(){ 
    angleInDegrees+=90 % 360;
    drawRotated(angleInDegrees);
    if(angleInDegrees == 360){  // add this lines
        angleInDegrees = 0
    }
});

Then you will get the desired result. Thanks. Hope this will help someone :)

git reset

If all you want is to undo an overzealous "git add" run:

git reset

Your changes will be unstaged and ready for you to re-add as you please.

DO NOT RUN git reset --hard.

It will not only unstage your added files, but will revert any changes you made in your working directory. If you created any new files in working directory, it will not delete them though.

There's a much easier approach using PrintWriter (see here)

Basically all you need is:

// set up URL connection
URL urlToRequest = new URL(urlStr);
HttpURLConnection urlConnection = (HttpURLConnection)urlToRequest.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

// write out form parameters
String postParamaters = "param1=value1&param2=value2"
urlConnection.setFixedLengthStreamingMode(postParameters.getBytes().length);
PrintWriter out = new PrintWriter(urlConnection.getOutputStream());
out.print(postParameters);
out.close();

// connect
urlConnection.connect();

include the xslx.js , xlsx.full.min.js , jszip.js

add a onchange event handler to the file input

function showDataExcel(event)
{
            var file = event.target.files[0];
            var reader = new FileReader();
            var excelData = [];
            reader.onload = function (event) {
                var data = event.target.result;
                var workbook = XLSX.read(data, {
                    type: 'binary'
                });

                workbook.SheetNames.forEach(function (sheetName) {
                    // Here is your object
                    var XL_row_object = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);

                    for (var i = 0; i < XL_row_object.length; i++)
                    {
                        excelData.push(XL_row_object[i]["your column name"]);

                    }

                    var json_object = JSON.stringify(XL_row_object);
                    console.log(json_object);
                    alert(excelData);
                })

            };

            reader.onerror = function (ex) {
                console.log(ex);
            };

            reader.readAsBinaryString(file);

}

I use printf, is shorter as it doesn't need flags to do the work:

printf "\rMy static $myvars composed text"

If optimizing for dev + production, you could try something like this in your config:

const dev = process.env.NODE_ENV !== 'production'

// in config

{
  devtool: dev ? 'eval-cheap-module-source-map' : 'source-map',
}

From the docs:

• devtool: "eval-cheap-module-source-map" offers SourceMaps that only maps lines (no column mappings) and are much faster
• devtool: "source-map" cannot cache SourceMaps for modules and need to regenerate complete SourceMap for the chunk. It’s something for production.

I am using webpack 2.1.0-beta.19

The Resource Override extension allows you to do exactly that:

• create a file rule for the url you want to replace
• edit the js/css/etc in the extension
• reload as often as you want :)

Someone commented about this apparently new functionality in Visual Studio 2013. I wasn't sure what he meant at first, but now that I do, I think it deserves its own answer.

We can use Console.WriteLine normally and the output is displayed, just not in the Output window, but in a new window after we click "Output" in the test details.

For updating a record:

 UPDATE Employees SET [Photo] = (SELECT
 MyImage.* from Openrowset(Bulk
 'C:\photo.bmp', Single_Blob) MyImage)
 where Id = 10

Notes:

• Make sure to add the 'BULKADMIN' Role Permissions for the login you are using.
• Paths are not pointing to your computer when using SQL Server Management Studio. If you start SSMS on your local machine and connect to a SQL Server instance on server X, the file C:\photo.bmp will point to hard drive C: on server X, not your machine!

I don't think IE supports the use of auto for setting height / width, so you could try giving this a numeric value (like Jarett suggests).

Also, it doesn't look like you are clearing your floats properly. Try adding this to your CSS for #container:

#container {
    height:100%;
    width:100%;
    overflow:hidden;
    /* for IE */
    zoom:1;
}

You can use itertools.repeat with operator.methodcaller to call the __call__ method of the function N times. Here is an example of a generator function doing it:

from itertools import repeat
from operator import methodcaller


def call_n_times(function, n):
    yield from map(methodcaller('__call__'), repeat(function, n))

Example of usage:

import random
from functools import partial

throw_dice = partial(random.randint, 1, 6)
result = call_n_times(throw_dice, 10)
print(list(result))
# [6, 3, 1, 2, 4, 6, 4, 1, 4, 6]

If you are using VB as code behind, you have to use bracket "()" instead of square bracket "[]".

Example for VB:

<script type="text/javascript">
var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>';
</script>  

I'll try a standard "Why are you doing it this way?" answer... Do you know about java.net.URL?

URL url = new URL(stringURL);

The above will throw a MalformedURLException if it can't parse the URL.

You can use LABJS or RequreJS

Script loaders like LABJS, RequireJS will improve the speed and quality of your code.

I tried several techniques, but settled on a slightly revised version of checking the Build.PRODUCT as below. This seems to vary quite a bit from emulator to emulator, that's why I have the 3 checks I currently have. I guess I could have just checked if product.contains("sdk") but thought the check below was a bit safer.

public static boolean isAndroidEmulator() {
    String model = Build.MODEL;
    Log.d(TAG, "model=" + model);
    String product = Build.PRODUCT;
    Log.d(TAG, "product=" + product);
    boolean isEmulator = false;
    if (product != null) {
        isEmulator = product.equals("sdk") || product.contains("_sdk") || product.contains("sdk_");
    }
    Log.d(TAG, "isEmulator=" + isEmulator);
    return isEmulator;
}

FYI - I found that my Kindle Fire had Build.BRAND = "generic", and some of the emulators didn't have "Android" for the network operator.

None of the above solutions address the generic intention of the original request. What if we don't know the id of the anchor? What if it doesn't have an id? What if it doesn't even have an href parameter (e.g. prev/next icon in a carousel)? What if we want to apply the action to multiple anchors with different models in an agnostic fashion? Here's an example that does something instead of a click, then later simulates the click (for any anchor or other tag):

var clicker = null;
$('a').click(function(e){ 
    clicker=$(this); // capture the clicked dom object
    /* ... do something ... */
    e.preventDefault(); // prevent original click action
});
clicker[0].click(); // this repeats the original click. [0] is necessary.

just use SQL :

disconnect; 

conn tiger/scott as sysdba;

Try this: add white-space: normal; to the style definition of the Bootstrap Button or you can replace the code you displayed with the one below

<div class="col-lg-3"> <!-- FIRST COL -->
  <div class="panel panel-default">
    <div class="panel-body"> 
    <h4>Posted on</h4>
    <p>22nd September 2013</p>
    <h4>Tags</h4>
    <a href="#" class="btn btn-primary btn-xs col-lg-12" style="margin-bottom:4px;white-space: normal;">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>
   <a href="#" class="btn btn-primary btn-xs col-lg-12" style="margin-bottom:4px;white-space: normal;">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>
   <a href="#" class="btn btn-primary btn-xs col-lg-12" style="margin-bottom:4px;white-space: normal;">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>
           </div>
  </div>
</div>

I have updated your fiddle here to show how it comes out.

Crossplatform solution for Linux, MacOS, Windows:

CORES=$(grep -c ^processor /proc/cpuinfo 2>/dev/null || sysctl -n hw.ncpu || echo "$NUMBER_OF_PROCESSORS")

final AlertDialog.Builder alert = new AlertDialog.Builder(mcontext);
alert.setTitle(title);
alert.setMessage(description);
alert.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
  @Override                                 
  public void onClick(DialogInterface dialog,int which) {
        cancelDialog(); //Implement method for canceling dialog
         }
   });
alert.show();
void cancelDialog()
{
   //Now you can either use  
   dialog.cancel();
    //or dialog.dismiss();
}

python3.6 -m pip install opencv-python

will install cv2 in linux in branch python3.6

I face this problem but resolution is very simple. I am writing the 1 MB file in 1024 Byte Buffer causing this issue. To Understand refer code before and After Fix.

Code with Excepion

DataOutputStream dos = new DataOutputStream(s.getOutputStream());
        FileInputStream fis = new FileInputStream(file);
        byte[] buffer = new byte[1024];
        
        while (fis.read(buffer) > 0) {
            dos.write(buffer);
        }
    

After Fixes:

DataOutputStream dos = new DataOutputStream(s.getOutputStream());
        FileInputStream fis = new FileInputStream(file);
        byte[] buffer = new byte[102400];
        
        while (fis.read(buffer) > 0) {
            dos.write(buffer);
        }

    

try this

webviewlayout.xml:

<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/help_webview"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:scrollbars="none"
/>

In your Activity:

WebView webView;
setContentView(R.layout.webviewlayout);
webView = (WebView)findViewById(R.id.help_webview);
webView.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.com");

Update

Add webView.setWebViewClient(new WebViewController()); to your Activity.

WebViewController class:

public class WebViewController extends WebViewClient {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}

You can only import a library which has been installed in your environment.

If you have created a new environment, e.g. to run an older version of Python, maybe you lack 'pandas' package, which is in the 'base' environment of Anaconda by default.

Fix through GUI

To add it to your environment, from the GUI, select your environment, select "All" in the dropdown list, type pandas in the text field, select the pandas package and Apply.

Afterwards, select 'Installed' to verify that the package has been correctly installed.

If you're using sqlplus in a shell, like bash you can run the shell's clear command from sqlplus:

SQL> host clear

you can abbreviate of course:

SQL> ho clear

.aspx uses a full lifecycle (Init, Load, PreRender) and can respond to button clicks etc.
An .ashx has just a single ProcessRequest method.

getElementById("id").removeAttribute("style");

if you are using jQuery then

$("#id").removeClass("classname");

Anyone getting this error with Azure build pipelines, try the below step to change environment variable of build agent

Add an Azure build pipeline task -> Azure powershell script:Inlinescript before Compile with below settings

- task: AzurePowerShell@3
  displayName: 'Azure PowerShell script: InlineScript'

You can use case in update and SWAP as many as you want

update Table SET column=(case when is_row_1 then value_2 else value_1 end) where rule_to_match_swap_columns

Here is a dplyr/tidyverse solution using the na_if() function:

dat %>% mutate_if(is.numeric, list(~na_if(., Inf)))

Note that this only replaces positive infinity with NA. Need to repeat if negative infinity values also need to be replaced.

dat %>% mutate_if(is.numeric, list(~na_if(., Inf))) %>% 
  mutate_if(is.numeric, list(~na_if(., -Inf)))

If you do not have to sign the app, right click on your project

Project Properties -> Signing -> uncheck "Sign the ClickOnce Manifest"

Also as this MS article suggests,

If you are using Visual Studio 2008 and are targeting .NET 3.5 and using automatic updates, you can just change the certificate and deploy a new version,

grep -Fxvf file1 file2

What the flags mean:

-F, --fixed-strings
              Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.    
-x, --line-regexp
              Select only those matches that exactly match the whole line.
-v, --invert-match
              Invert the sense of matching, to select non-matching lines.
-f FILE, --file=FILE
              Obtain patterns from FILE, one per line.  The empty file contains zero patterns, and therefore matches nothing.

The selected answer makes it sound slightly more complex than it is, the following is what you need (install npm first on your system).

npm install -g elasticdump
elasticdump --input=http://mysrc.com:9200/my_index --output=http://mydest.com:9200/my_index --type=mapping
elasticdump --input=http://mysrc.com:9200/my_index --output=http://mydest.com:9200/my_index --type=data

You can skip the first elasticdump command for subsequent copies if the mappings remain constant.

I have just done a migration from AWS to Qbox.io with the above without any problems.

                    leveraging Bulk API copying data inside the same
                    elasticsearch instance.
                    (default: false)
--timeout
                    Integer containing the number of milliseconds to wait for
                    a request to respond before aborting the request. Passed
                    directly to the request library. If used in bulk writing,
                    it will result in the entire batch not being written.
                    Mostly used when you don't care too much if you lose some
                    data when importing but rather have speed.
--skip
                    Integer containing the number of rows you wish to skip
                    ahead from the input transport.  When importing a large
                    index, things can go wrong, be it connectivity, crashes,
                    someone forgetting to `screen`, etc.  This allows you
                    to start the dump again from the last known line written
                    (as logged by the `offset` in the output).  Please be
                    advised that since no sorting is specified when the
                    dump is initially created, there's no real way to
                    guarantee that the skipped rows have already been
                    written/parsed.  This is more of an option for when
                    you want to get most data as possible in the index
                    without concern for losing some rows in the process,
                    similar to the `timeout` option.
--inputTransport
                    Provide a custom js file to us as the input transport
--outputTransport
                    Provide a custom js file to us as the output transport
--toLog
                    When using a custom outputTransport, should log lines
                    be appended to the output stream?

The answer is quite simple:

DateTime Today = DateTime.Today;
string zeroBased = Today.ToString("yy-MM-dd");

Update: For Python 3, check Ben's answer

To attach a message to the current exception and re-raise it: (the outer try/except is just to show the effect)

For python 2.x where x>=6:

try:
    try:
      raise ValueError  # something bad...
    except ValueError as err:
      err.message=err.message+" hello"
      raise              # re-raise current exception
except ValueError as e:
    print(" got error of type "+ str(type(e))+" with message " +e.message)

This will also do the right thing if err is derived from ValueError. For example UnicodeDecodeError.

Note that you can add whatever you like to err. For example err.problematic_array=[1,2,3].

Edit: @Ducan points in a comment the above does not work with python 3 since .message is not a member of ValueError. Instead you could use this (valid python 2.6 or later or 3.x):

try:
    try:
      raise ValueError
    except ValueError as err:
       if not err.args: 
           err.args=('',)
       err.args = err.args + ("hello",)
       raise 
except ValueError as e:
    print(" error was "+ str(type(e))+str(e.args))

Edit2:

Depending on what the purpose is, you can also opt for adding the extra information under your own variable name. For both python2 and python3:

try:
    try:
      raise ValueError
    except ValueError as err:
       err.extra_info = "hello"
       raise 
except ValueError as e:
    print(" error was "+ str(type(e))+str(e))
    if 'extra_info' in dir(e):
       print e.extra_info

The other answers don't work for me. I'm trying to get the command line working in Jenkins. All you need are the following command line arguments:

--non-interactive

--trust-server-cert

Try this:

var options = {
    url:  'http://url',
    timeout: 120000
}

request(options, function(err, resp, body) {});

Refer to request's documentation for other options.

Alternatively, if the method on Child is truly static (not a product of current props, state) you can define it on statics and then access it as you would a static class method. For example:

var Child = React.createClass({
  statics: {
    someMethod: function() {
      return 'bar';
    }
  },
  // ...
});

console.log(Child.someMethod()) // bar

For individual variables you want to make available on a one off basis you can make it part of the command.

sudo http_proxy=$http_proxy wget "http://stackoverflow.com"

I had this problem when creating a new table. It turns out the Foreign Key name I gave was already in use. Renaming the key fixed it.

Reasons have been given in other answers; here is another.

std::map (balanced binary tree) operations are amortized O(log n) and worst case O(log n). std::unordered_map (hash table) operations are amortized O(1) and worst case O(n).

How this plays out in practice is that the hash table "hiccups" every once in a while with an O(n) operation, which may or may not be something your application can tolerate. If it can't tolerate it, you'd prefer std::map over std::unordered_map.

Passsing bitmap as parceable in bundle between activity is not a good idea because of size limitation of Parceable(1mb). You can store the bitmap in a file in internal storage and retrieve the stored bitmap in several activities. Here's some sample code.

To store bitmap in a file myImage in internal storage:

public String createImageFromBitmap(Bitmap bitmap) {
    String fileName = "myImage";//no .png or .jpg needed
    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
        fo.write(bytes.toByteArray());
        // remember close file output
        fo.close();
    } catch (Exception e) {
        e.printStackTrace();
        fileName = null;
    }
    return fileName;
}

Then in the next activity you can decode this file myImage to a bitmap using following code:

//here context can be anything like getActivity() for fragment, this or MainActivity.this
Bitmap bitmap = BitmapFactory.decodeStream(context.openFileInput("myImage"));

Note A lot of checking for null and scaling bitmap's is ommited.

To check for the NULL data for column1 and consider your datatype of it is String, you could use below command :

select * from tbl_name where column1 is null or column1 <> '';

To declare a string literal as an output column, leave the Table off and just use Test. It doesn't need to be associated with a table among your joins, since it will be accessed only by its column alias. When using a metadata function like getColumnMeta(), the table name will be an empty string because it isn't associated with a table.

SELECT
  `field1`, 
  `field2`, 
  'Test' AS `field3` 
FROM `Test`;

Note: I'm using single quotes above. MySQL is usually configured to honor double quotes for strings, but single quotes are more widely portable among RDBMS.

If you must have a table alias name with the literal value, you need to wrap it in a subquery with the same name as the table you want to use:

SELECT
  field1,
  field2,
  field3
FROM 
  /* subquery wraps all fields to put the literal inside a table */
  (SELECT field1, field2, 'Test' AS field3 FROM Test) AS Test

Now field3 will come in the output as Test.field3.

On the above example I kept losing the values, I think that delaying the Validation will allow the new data types to be saved as part of the meta data.

On the connection Manager for 'Excel Connection Manager' set the Delay Validation to False from the Properties.

Then on the data flow Destination task for Excel set the ValidationExternalMetaData to False, again from the properties.

This will now allow you to right click on the Excel Destination Task and go to Advanced Editor for Excel Destination --> far right tab - Input and Output Properties. In the External Columns folder section you will be able to now change the Data Types and Length values of the problematic columns and this can now be saved.

Good Luck!

Attention, wrong answer coming! But anyone without apache libraries or so might find

compileSdkVersion 23
buildToolsVersion "23.0.0"



//...


dependencies {
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:design:23.0.0'    

}

helpful, it did the trick for me.

^[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,7}$

[domain - lower case letters and 0-9 only] [can have a hyphen] + [TLD - lower case only, must be beween 2 and 7 letters long]
http://rubular.com/ is brilliant for testing regular expressions!
Edit: Updated TLD maximum to 7 characters for '.rentals' as Dan Caddigan pointed out.

Double click the file.txt, then save it, command + s, that worked in my case. Also, make sure the file.txt is saved in the project folder. If that does not work.

PrintWriter pw = new PrintWriter(new File("file.txt"));
pw.println("hello world"); // to test if it works.

You can use the undocumented function _get_numeric_data() to filter only numeric columns:

df._get_numeric_data()

Example:

In [32]: data
Out[32]:
   A  B
0  1  s
1  2  s
2  3  s
3  4  s

In [33]: data._get_numeric_data()
Out[33]:
   A
0  1
1  2
2  3
3  4

Note that this is a "private method" (i.e., an implementation detail) and is subject to change or total removal in the future. Use with caution.

In SQL Server you can combine TABLESAMPLE with NEWID() to get pretty good randomness and still have speed. This is especially useful if you really only want 1, or a small number, of rows.

SELECT TOP 1 * FROM [table] 
TABLESAMPLE (500 ROWS) 
ORDER BY NEWID()

In order to show the DataFrame in Jupyter Notebook just type:

   display(Name_of_the_DataFrame)

for example:

  display(df)

sp_who2 will actually provide a list of connections for the database server, not a database. To view connections for a single database (YourDatabaseName in this example), you can use

DECLARE @AllConnections TABLE(
    SPID INT,
    Status VARCHAR(MAX),
    LOGIN VARCHAR(MAX),
    HostName VARCHAR(MAX),
    BlkBy VARCHAR(MAX),
    DBName VARCHAR(MAX),
    Command VARCHAR(MAX),
    CPUTime INT,
    DiskIO INT,
    LastBatch VARCHAR(MAX),
    ProgramName VARCHAR(MAX),
    SPID_1 INT,
    REQUESTID INT
)

INSERT INTO @AllConnections EXEC sp_who2

SELECT * FROM @AllConnections WHERE DBName = 'YourDatabaseName'

(Adapted from SQL Server: Filter output of sp_who2.)

You don't need the jsp:useBean to set the model if you already have a controller which prepared the model.

Just access it plain by EL:

<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>

or by JSTL <c:out> tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:

<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>

See also:

• Our Servlets wiki page

Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.

session.setAttribute("questions", questions);

and alter EL accordingly to use ${questions}.

Also note that you don't have any JSTL tag in your code. It's all plain JSP.

I'm using version 4.4.2 and none of the other answers worked for me. But adding useMongoClient to the options and putting it into a variable that you call close on seemed to work.

var db = mongoose.connect('mongodb://localhost:27017/somedb', { useMongoClient: true })

//do stuff

db.close()

I also come here for the same problem, The solution I found is to install npm and then restart the Visual Studio Code

You need to set ulimit -c. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited and check if everything is correct ulimit -a. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>.

@AnandaMahto has addressed why you're getting these results and provided the clearest way to get what you want. But another option would be to use identical instead of ==.

test$ID <- ifelse(is.na(test$time) | sapply(as.character(test$type), identical, "A"), NA, "1")

Or use isTRUE:

test$ID <- ifelse(is.na(test$time) | Vectorize(isTRUE)(test$type == "A"), NA, "1")

You can use max(value, run)

The function max takes any number of arguments, or (alternatively) an iterable, and returns the maximum value.

Yes. Recent versions of IE (IE8 or above) let you adjust that. Here's how:

• Fire up Internet Explorer.
• Click the 'Tools' menu, then click 'Developer Tools'. Alternatively, just press F12.

That should open the Developer Tools window. That window has two menu items that are of interest:

• Browser Mode. This setting determines the value of the user-agent header sent for every request.
• Document Mode. This setting determines how the rendering engine renders the page.

More at http://blogs.msdn.com/b/ie/archive/2010/06/16/ie-s-compatibility-features-for-site-developers.aspx

The option that I tend to use, mostly because it's simple and I don't have to think, is using Write-Output as below. Write-Output will put an EOL marker in the string for you and you can simply output the finished string.

Write-Output $stringThatNeedsEOLMarker | Out-File -FilePath PathToFile -Append

Alternatively, you could also just build the entire string using Write-Output and then push the finished string into Out-File.

You need to add an instance of the class:

lstemail.Add(new EmailData { FirstName = "John", LastName = "Smith", Location = "Los Angeles"});

I would recommend adding a constructor to your class, however:

public class EmailData
{
    public EmailData(string firstName, string lastName, string location)
    {
        this.FirstName = firstName;
        this.LastName = lastName;
        this.Location = location;
    }
    public string FirstName{ set; get; }
    public string LastName { set; get; }
    public string Location{ set; get; }
}

This would allow you to write the addition to your list using the constructor:

lstemail.Add(new EmailData("John", "Smith", "Los Angeles"));

Like this?

 System.out.println(Name + " " + Income);

You have to add reference to

Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll 

It can be found at C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies\ directory (for VS2010 professional or above; .NET Framework 4.0).

or right click on your project and select: Add Reference... > .NET:

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

In my case, it was just because there were no source file in the target. All of my library was template with source code in the header. Adding an empty file.cpp solved the problem.

You could use this query to display Foreign key constaraints:

SELECT
K_Table = FK.TABLE_NAME,
FK_Column = CU.COLUMN_NAME,
PK_Table = PK.TABLE_NAME,
PK_Column = PT.COLUMN_NAME,
Constraint_Name = C.CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS C
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS FK ON C.CONSTRAINT_NAME = FK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS PK ON C.UNIQUE_CONSTRAINT_NAME = PK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE CU ON C.CONSTRAINT_NAME = CU.CONSTRAINT_NAME
INNER JOIN (
SELECT i1.TABLE_NAME, i2.COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS i1
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE i2 ON i1.CONSTRAINT_NAME = i2.CONSTRAINT_NAME
WHERE i1.CONSTRAINT_TYPE = 'PRIMARY KEY'
) PT ON PT.TABLE_NAME = PK.TABLE_NAME
---- optional:
ORDER BY
1,2,3,4
WHERE PK.TABLE_NAME='YourTable'

1. Start -> Run -> perfmon
2. Look at the zillions of counters that SQL Server installs

The first method if (isset($arr['1'])) will not work on an associative array.

For example, the following code displays "Nope, not more than one."

$arr = array(
    'a' => 'apple',
    'b' => 'banana',
);

if (isset($arr['1'])) {
    echo "Yup, more than one.";
} else {
    echo "Nope, not more than one.";
}

No, because the commit message is related with the commit SHA / hash, and if we change it the commit SHA is also changed. The way I used is to create a comment on that commit. I can't think the other way.

If you aren't actually restricted to keeping all of these elements as sibling nodes you can wrap the ones that go together in another default flex box, and have the container of both use space-between.

.space-between {_x000D_
  border: 1px solid red;_x000D_
  display: flex;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
.default-flex {_x000D_
  border: 1px solid blue;_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid;_x000D_
}

<div class="space-between">_x000D_
  <div class="child">1</div>_x000D_
  <div class="default-flex">_x000D_
    <div class="child">2</div>_x000D_
    <div class="child">3</div>_x000D_
    <div class="child">4</div>_x000D_
    <div class="child">5</div>_x000D_
  </div>_x000D_
</div>

Or if you were doing the same thing with flex-start and flex-end reversed you just swap the order of the default-flex container and lone child.

This doesn't use string formatting, but you should be able to do:

print 'this is a tuple ', (1, 2, 3)

If you really want to use string formatting:

print 'this is a tuple %s' % str((1, 2, 3))
# or
print 'this is a tuple %s' % ((1, 2, 3),)

Note, this assumes you are using a Python version earlier than 3.0.

window.oncontextmenu = function () {
return false;
}

might help you.

I know the answer given and asked for is assumed for Scala, so I am just providing a little snippet of Python code in case a PySpark user is curious. The syntax is similar to the given answer, but to properly pop the list out I actually have to reference the column name a second time in the mapping function and I do not need the select statement.

i.e. A DataFrame, containing a column named "Raw"

To get each row value in "Raw" combined as a list where each entry is a row value from "Raw" I simply use:

MyDataFrame.rdd.map(lambda x: x.Raw).collect()

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

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

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

var bgPositionTimer = setBgPosition();

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

clearInterval(bgPositionTimer);

An example use case would be:

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

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

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

If you really want it to look more semantic like having the <body> in the middle you can use the <main> element. With all the recent advances the <body>element is not as semantic as it once was but you just have to think of it as a wrapper in which the view port sees.

<html>
    <head>
    </head>
    <body>
        <header>
        </header>
        <main>
            <section></section>
            <article></article>
        </main>
        <footer>
        </footer>
    <body>
</html>

I added the file to the index:

git add file_name

and then ran:

git diff --cached file_name
