the modern answer for this should be using Kotlin's no-arg compiler plugin which creates a non argument construct code for classic apies more about here

simply you have to add the plugin class path in build.gradle project level

    dependencies {
    ....

    classpath "org.jetbrains.kotlin:kotlin-noarg:1.4.10"

    ....
    }

then configure your annotation to generate the no-arg constructor

apply plugin: "kotlin-noarg"

noArg {
      annotation("your.path.to.annotaion.NoArg")
      invokeInitializers = true
}

then define your annotation file NoArg.kt

 @Target(AnnotationTarget.CLASS)
 @Retention(AnnotationRetention.SOURCE)
 annotation class NoArg

finally in any data class you can simply use your own annotation

@NoArg
data class SomeClass( val datafield:Type , ...   )

I used to create my own no-arg constructor as the accepted answer , which i got by search but then this plugin released or something and I found it way cleaner .

You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.

If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

A bit of encoding can solve this:

Client Side:

message = input("->")
clientSocket.sendto(message.encode('utf-8'), (address, port))

Server Side:

data = s.recv(1024)
modifiedMessage, serverAddress = clientSocket.recvfrom(message.decode('utf-8'))

Delete rows from dbo_MigrationHistory table or delete the table and run

update-database -verbose

It will run all the migrations in your project one by one

Based on the answer of @macetw I print the exception directly to stderr in a decorator.

Python 3

from functools import wraps
from sys import stderr
from traceback import format_exc
from typing import Callable, Collection, Any, Mapping


def force_error_output(func: Callable):
    @wraps(func)
    def forced_error_output(*args: Collection[Any], **kwargs: Mapping[str, Any]):
        nonlocal func

        try:
            func(*args, **kwargs)
        except Exception as exception:
            stderr.write(format_exc())
            stderr.write("\n")
            stderr.flush()

            raise exception

    return forced_error_output

Python 2

from functools import wraps
from sys import stderr
from traceback import format_exc


def force_error_output(func):
    @wraps(func)
    def forced_error_output(*args, **kwargs):
        try:
            func(*args, **kwargs)
        except Exception as exception:
            stderr.write(format_exc())
            stderr.write("\n")
            stderr.flush()

            raise exception

    return forced_error_output

Then in your worker just use the decorator

@force_error_output
def da_worker(arg1: int, arg2: str):
    pass

With Python3x, you need to convert your string to raw bytes. You would have to encode the string as bytes. Over the network you need to send bytes and not characters. You are right that this would work for Python 2x since in Python 2x, socket.sendto on a socket takes a "plain" string and not bytes. Try this:

print("UDP target IP:", UDP_IP)
print("UDP target port:", UDP_PORT)
print("message:", MESSAGE)

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.sendto(bytes(MESSAGE, "utf-8"), (UDP_IP, UDP_PORT))

If you are sending this through your own mail server you might need to add a "Sender" header which will contain an email address of from your own domain. Gmail will probably be spamming the email because the FROM address is a gmail address but has not been sent from their own server.

from foo import * 

adds all the names without leading underscores (or only the names defined in the modules __all__ attribute) in foo into your current module.

In the above code with from socket import * you just want to catch timeout as you've pulled timeout into your current namespace.

from socket import * pulls in the definitions of everything inside of socket but doesn't add socket itself.

try:
    # socketstuff
except timeout:
    print 'caught a timeout'

Many people consider import * problematic and try to avoid it. This is because common variable names in 2 or more modules that are imported in this way will clobber one another.

For example, consider the following three python files:

# a.py
def foo():
    print "this is a's foo function"

# b.py
def foo():
    print "this is b's foo function"

# yourcode.py
from a import *
from b import *
foo()

If you run yourcode.py you'll see just the output "this is b's foo function".

For this reason I'd suggest either importing the module and using it or importing specific names from the module:

For example, your code would look like this with explicit imports:

import socket
from socket import AF_INET, SOCK_DGRAM

def main():
    client_socket = socket.socket(AF_INET, SOCK_DGRAM)
    client_socket.settimeout(1)
    server_host = 'localhost'
    server_port = 1234
    while(True):
        client_socket.sendto('Message', (server_host, server_port))
        try:
            reply, server_address_info = client_socket.recvfrom(1024)
            print reply
        except socket.timeout:
            #more code

Just a tiny bit more typing but everything's explicit and it's pretty obvious to the reader where everything comes from.

I have developed this functionality from one Blog. There are 2 ways you can send SMS.

1. Open native SMS composer
2. write your message and send from your Android application

This is the code of 1st method.

Main.xml

<?xml version="1.0" encoding="utf-8"?>  
    <RelativeLayout  
        android:id="@+id/relativeLayout1"  
        android:layout_width="fill_parent"  
        android:layout_height="fill_parent"  
        xmlns:android="http://schemas.android.com/apk/res/android">  

            <Button  
                android:id="@+id/btnSendSMS"  
               android:layout_height="wrap_content"  
               android:layout_width="wrap_content"  
               android:text="Send SMS"  
               android:layout_centerInParent="true"  
               android:onClick="sendSMS">  
           </Button>  
   </RelativeLayout>

Activity

public class SendSMSActivity extends Activity {  
     /** Called when the activity is first created. */  
     @Override  
     public void onCreate(Bundle savedInstanceState) {  
         super.onCreate(savedInstanceState);  
         setContentView(R.layout.main);  
      }  

     public void sendSMS(View v)  
     {  
         String number = "12346556";  // The number on which you want to send SMS  
         startActivity(new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", number, null)));  
     }  
    /* or 
     public void sendSMS(View v) 
      { 
     Uri uri = Uri.parse("smsto:12346556"); 
         Intent it = new Intent(Intent.ACTION_SENDTO, uri); 
         it.putExtra("sms_body", "Here you can set the SMS text to be sent"); 
         startActivity(it); 
      } */  
 }

NOTE:- In this method, you don’t require SEND_SMS permission inside the AndroidManifest.xml file.

For 2nd method refer to this BLOG. You will find a good explanation from here.

Hope this will help you...

Also you need to check if individual record is not getting updated in the logic because with update trigger in the place causes time out error too.

So, the solution is to make sure you perform bulk update after the loop/cursor instead of one record at a time in the loop.

    public static void PrintFileToDefaultPrinter(string FilePath)
    {
        try
        {
            var file = File.ReadAllBytes(FilePath);
            var printQueue = LocalPrintServer.GetDefaultPrintQueue();

            using (var job = printQueue.AddJob())
            using (var stream = job.JobStream)
            {
                stream.Write(file, 0, file.Length);
            }
        }
        catch (Exception)
        {

            throw;
        }
    }

This can be done very straightforwardly.

Define your struct explicitly with [StructLayout(LayoutKind.Explicit)]

int size = list.GetLength(0);
IntPtr addr = Marshal.AllocHGlobal(size * sizeof(DataStruct));
DataStruct *ptrBuffer = (DataStruct*)addr;
foreach (DataStruct ds in list)
{
    *ptrBuffer = ds;
    ptrBuffer += 1;
}

This code can only be written in an unsafe context. You have to free addr when you're done with it.

Marshal.FreeHGlobal(addr);

When I had this problem, I had included the mail-api.jar in my maven pom file. That's the API specification only. The fix is to replace this:

<!-- DO NOT USE - it's just the API, not an implementation -->
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>

with the reference implementation of that api:

<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>

I know it has sun in the package name, but that's the latest version. I learned this from https://stackoverflow.com/a/28935760/1128668

Using preprocessor directives is considered evil most of the time. Ideally you want to avoid them like the Pest. Remember that making the compiler understand your code is easy, allowing other programmers to understand your code is much harder. A few dozen cases like this here and there makes it very hard to read for yourself later or for others right now.

One way might be to put your parameters together into some sort of argument class. You could then use only a subset of the variables (equivalent to your assigning 0 really) or having different specializations of that argument class for each platform. This might however not be worth it, you need to analyze whether it would fit.

If you can read impossible templates, you might find advanced tips in the "Exceptional C++" book. If the people who would read your code could get their skillset to encompass the crazy stuff taught in that book, then you would have beautiful code which can also be easily read. The compiler would also be well aware of what you are doing (instead of hiding everything by preprocessing)

I had the same issue however with doing an upload of a very large file using a python-requests client posting to a nginx+uwsgi backend.

What ended up being the cause was the the backend had a cap on the max file size for uploads lower than what the client was trying to send.

The error never showed up in our uwsgi logs since this limit was actually one imposed by nginx.

Upping the limit in nginx removed the error.

I encountered this issue, and I managed to identify a specific cause, which isn't mentioned above either in answers or the question.

I am running a full js stack, angular front end and node back end on SSL, and the API is on a different domain running on port 8081, so I am doing CORS requests and withCredentials as I am dropping a session cookie from the API

So specifically my scenario was: POST request, withCredentials to port 8081 caused the "CAUTION: provisional headers are shown" message in the inspector and also of course blocked the request all together.

My solution was to set up apache to proxy pass the request from the usual SSL port of 443 to the node SSL port of 8081 (node has to be on a higher port as it cannot be ran as root in prod). So I guess Chrome doesn't like SSL requests to unconventional SSL ports, but perhaps their error message could be more specific.

So I had the same issue, but it was because I was saving the access token but not using it. It could be because I'm super sleepy because of due dates, or maybe I just didn't think about it! But in case anyone else is in the same situation:

When I log in the user I save the access token:

$facebook = new Facebook(array(
    'appId' => <insert the app id you get from facebook here>,
    'secret' => <insert the app secret you get from facebook here>
));

$accessToken = $facebook->getAccessToken();
//save the access token for later

Now when I make requests to facebook I just do something like this:

$facebook = new Facebook(array(
    'appId' => <insert the app id you get from facebook here>,
    'secret' => <insert the app secret you get from facebook here>
));

$facebook->setAccessToken($accessToken);
$facebook->api(... insert own code here ...)

Use django-widget-tweaks, it is easy to use and works pretty well.

Otherwise this can be done using a custom template filter.

Considering you render your form this way :

<form action="/contact/" method="post">
    {{ form.non_field_errors }}
    <div class="fieldWrapper">
        {{ form.subject.errors }}
        <label for="id_subject">Email subject:</label>
        {{ form.subject }}
    </div>
</form>

form.subject is an instance of BoundField which has the as_widget method.

you can create a custom filter "addcss" in "my_app/templatetags/myfilters.py"

from django import template

register = template.Library()

@register.filter(name='addcss')
def addcss(value, arg):
    css_classes = value.field.widget.attrs.get('class', '').split(' ')
    if css_classes and arg not in css_classes:
        css_classes = '%s %s' % (css_classes, arg)
    return value.as_widget(attrs={'class': css_classes})

And then apply your filter:

{% load myfilters %}
<form action="/contact/" method="post">
    {{ form.non_field_errors }}
    <div class="fieldWrapper">
        {{ form.subject.errors }}
        <label for="id_subject">Email subject:</label>
        {{ form.subject|addcss:'MyClass' }}
    </div>
</form>

form.subjects will then be rendered with the "MyClass" css class.

Hope this help.

EDIT 1

• Update filter according to dimyG's answer

• Add django-widget-tweak link

EDIT 2

• Update filter according to Bhyd's comment

It turns out I didn't have Microsoft visual c++ installed, installing it solved the problem for me.

You can use:

dir /s

If you need the list without all the header/footer information try this:

dir /s /b

(For sure this will work for DOS 6 and later; might have worked prior to that, but I can't recall.)

Had a need for similar functionality myself, so after much hair pulling I came up with the function below

/**
 * Fetches angle relative to screen centre point
 * where 3 O'Clock is 0 and 12 O'Clock is 270 degrees
 * 
 * @param screenPoint
 * @return angle in degress from 0-360.
 */
public double getAngle(Point screenPoint) {
    double dx = screenPoint.getX() - mCentreX;
    // Minus to correct for coord re-mapping
    double dy = -(screenPoint.getY() - mCentreY);

    double inRads = Math.atan2(dy, dx);

    // We need to map to coord system when 0 degree is at 3 O'clock, 270 at 12 O'clock
    if (inRads < 0)
        inRads = Math.abs(inRads);
    else
        inRads = 2 * Math.PI - inRads;

    return Math.toDegrees(inRads);
}

Don't really know how they compare for speed, but the first one looks like the right idea for scaling to really big JSON data, since it parses only a small chunk at a time so they don't need to hold all the data in memory at once (This can be faster or slower depending on the library/use case)

I think the project you are looking for is: https://github.com/sarxos/webcam-capture (I'm the author)

There is an example working exactly as you've described - after it's run, the window appear where, after you press "Start" button, you can see live image from webcam device and save it to file after you click on "Snapshot" (source code available, please note that FPS counter in the corner can be disabled):

The project is portable (WinXP, Win7, Win8, Linux, Mac, Raspberry Pi) and does not require any additional software to be installed on the PC.

API is really nice and easy to learn. Example how to capture single image and save it to PNG file:

Webcam webcam = Webcam.getDefault();
webcam.open();
ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));

Here is my version of animated image control. You can use standard property Source for specifying image source. I further improved it. I am a russian, project is russian so comments are also in Russian. But anyway you should be able understand everything without comments. :)

The answer above didn't work for me on one of my servers, something to to with basedir, so I re-hashed it a little. The code below works on all my servers.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$a = curl_exec($ch);
curl_close( $ch ); 
// the returned headers
$headers = explode("\n",$a);
// if there is no redirection this will be the final url
$redir = $url;
// loop through the headers and check for a Location: str
$j = count($headers);
for($i = 0; $i < $j; $i++){
// if we find the Location header strip it and fill the redir var       
if(strpos($headers[$i],"Location:") !== false){
        $redir = trim(str_replace("Location:","",$headers[$i]));
        break;
    }
}
// do whatever you want with the result
echo redir;

var swap = function () {
    var divs = document.getElementsByTagName('div');
    var div1 = divs[0];
    var div2 = divs[1];
    var div3 = divs[2];

    div3.parentNode.insertBefore(div1, div3);
    div1.parentNode.insertBefore(div3, div2);
};

This function may seem strange, but it heavily relies on standards in order to function properly. In fact, it may seem to function better than the jQuery version that tvanfosson posted which seems to do the swap only twice.

What standards peculiarities does it rely on?

insertBefore Inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children. If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed.

It's a UILabel subclass so you can just drop it in, and then to change the line height:

myLabel.lineHeightMultiple = 0.85;
myLabel.leading = 2;

Use the splat operator(*)

By default, * operator prints list separated by space. Use sep operator to specify the delimiter

print(*sys.path, sep = "\n")

I have come to this question and the one below several times.

how to call scalar function in sql server 2008

Each time, I try entering the Function using the syntax shown here in SQL Server Management Studio, or SSMS, to see the results, and each time I get the errors.

For me, that is because my result set is in tabular data format. Therefore, to see the results in SSMS, I have to call it like this:

SELECT * FROM dbo.Afisho_rankimin_TABLE(5);

I understand that the author's question involved a scalar function, so this answer is only to help others who come to StackOverflow often when they have a problem with a query (like me).

I hope this helps others.

For an Ant project:

Make sure, you have servlet-api.jar in the lib folder.

For a Maven project:

Make sure, you have the dependency added in POM.xml.

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.1.0</version>
  <scope>provided</scope>
</dependency>

Another way to do it is: Update the project facets to pick up the right server.

Check this box in this location:

Project ? Properties ? Target Runtimes ? Apache Tomcat (any server)

My solution is fairly simple:

Load the environment config in ./config/index.js

var env = process.env.NODE_ENV || 'development'
  , cfg = require('./config.'+env);

module.exports = cfg;

Define some defaults in ./config/config.global.js

var config = module.exports = {};

config.env = 'development';
config.hostname = 'dev.example.com';

//mongo database
config.mongo = {};
config.mongo.uri = process.env.MONGO_URI || 'localhost';
config.mongo.db = 'example_dev';

Override the defaults in ./config/config.test.js

var config = require('./config.global');

config.env = 'test';
config.hostname = 'test.example';
config.mongo.db = 'example_test';

module.exports = config;

Using it in ./models/user.js:

var mongoose = require('mongoose')
, cfg = require('../config')
, db = mongoose.createConnection(cfg.mongo.uri, cfg.mongo.db);

Running your app in test environment:

NODE_ENV=test node ./app.js

MAKE THIS YOUR config.js file code

CKEDITOR.editorConfig = function( config ) {

   //   config.enterMode = 2; //disabled <p> completely
        config.enterMode = CKEDITOR.ENTER_BR // pressing the ENTER KEY input <br/>
        config.shiftEnterMode = CKEDITOR.ENTER_P; //pressing the SHIFT + ENTER KEYS input <p>
        config.autoParagraph = false; // stops automatic insertion of <p> on focus
    };

Try this,

$('td').click(function(){
   var row_index = $(this).parent().index();
   var col_index = $(this).index();
});

If you need the index of table contain td then you can change it to

var row_index = $(this).parent('table').index(); 

Python doesn't subscribe to the idea that exceptions should only be used for exceptional cases, in fact the idiom is 'ask for forgiveness, not permission'. This means that using exceptions as a routine part of your flow control is perfectly acceptable, and in fact, encouraged.

This is generally a good thing, as working this way helps avoid some issues (as an obvious example, race conditions are often avoided), and it tends to make code a little more readable.

Imagine you have a situation where you take some user input which needs to be processed, but have a default which is already processed. The try: ... except: ... else: ... structure makes for very readable code:

try:
   raw_value = int(input())
except ValueError:
   value = some_processed_value
else: # no error occured
   value = process_value(raw_value)

Compare to how it might work in other languages:

raw_value = input()
if valid_number(raw_value):
    value = process_value(int(raw_value))
else:
    value = some_processed_value

Note the advantages. There is no need to check the value is valid and parse it separately, they are done once. The code also follows a more logical progression, the main code path is first, followed by 'if it doesn't work, do this'.

The example is naturally a little contrived, but it shows there are cases for this structure.

In asp.net Core / MVC 6 rc2 you can set the HttpContext

var SomeController controller = new SomeController();

controller.ControllerContext = new ControllerContext();
controller.ControllerContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();

rc 1 was

var SomeController controller = new SomeController();

controller.ActionContext = new ActionContext();
controller.ActionContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();

https://stackoverflow.com/a/34022964/516748

Consider using Moq

new Mock<ISession>();

It looks like you were on the right path. Here is the one-liner you were looking for:

df.reset_index().T.drop_duplicates().T

But since there is no example data frame that produces the referenced error message Reindexing only valid with uniquely valued index objects, it is tough to say exactly what would solve the problem. if restoring the original index is important to you do this:

original_index = df.index.names
df.reset_index().T.drop_duplicates().reset_index(original_index).T

.values()

You can call the values() method on your enum.

for (Direction dir : Direction.values()) {
  // do what you want
}

This values() method is implicitly declared by the compiler. So it is not listed on Enum doc.

I found that pathlib module also supports this.

from pathlib import Path
>>> Path.home()
WindowsPath('C:/Users/XXX')

You can HashMap<MyHashObject,MyHashObject> instead of HashSet<MyHashObject>.

Calling ContainsKey() on your "reconstructed" MyHashObject will first hashCode()-check the collection, and if a duplicate hashcode is hit, finally equals()-check your "reconstructed" against the original, at which you can retrieve the original using get()

This is O(1) but the downside is you will likely have to override both equals() and hashCode() methods.

Does this work? Untested but should get the point across.

UPDATE FUNCTIONS
SET Func_TaxRef = 
(
  SELECT Min(TAX.Tax_Code) AS MinOfTax_Code
  FROM TAX, FUNCTIONS F1
  WHERE F1.Func_Pure <= [Tax_ToPrice]
    AND F1.Func_Year=[Tax_Year]
    AND F1.Func_ID = FUNCTIONS.Func_ID
  GROUP BY F1.Func_ID;
)

Basically for each row in FUNCTIONS, the subquery determines the minimum current tax code and sets FUNCTIONS.Func_TaxRef to that value. This is assuming that FUNCTIONS.Func_ID is a Primary or Unique key.

You can't do it with only Javascript. You'll need some server-side code (PHP, in your case) that serves as a proxy between the DB and the client-side code.

If you need to support IE6, use JavaScript so manage the size of the wrapper div (set the position of the element in pixels after reading the window size). If you don't want to use JavaScript, then this can't be done. There are workarounds but expect a week or two to make it work in every case and in every browser.

For other modern browsers, use this css:

position: absolute;
top: 60px;
bottom: 0px;

Try passing it directly to the ng-click function:

<div class="col-lg-1 text-center">
    <span class="glyphicon glyphicon-trash" data="{{event.id}}"
          ng-click="deleteEvent(event.id)"></span>
</div>

Then it should be available in your handler:

$scope.deleteEvent=function(idPassedFromNgClick){
    console.log(idPassedFromNgClick);
}

Here's an example

One command on the same row should always be faster than two on that same row. So the UPDATE only would be better.

EDIT set up the table:

create table YourTable
(YourName  varchar(50)  primary key
,Tag int
)

insert into YourTable values ('first value',1)

run this, which takes 1 second on my system (sql server 2005):

SET NOCOUNT ON
declare @x int
declare @y int
select @x=0,@y=0
UPDATE YourTable set YourName='new name'
while @x<10000
begin
    Set @x=@x+1
    update YourTable set YourName='new name' where YourName='new name'
    SET @y=@y+@@ROWCOUNT
end
print @y

run this, which took 2 seconds on my system:

SET NOCOUNT ON
declare @x int
declare @y int
select @x=0,@y=0
while @x<10000
begin
    Set @x=@x+1
    DELETE YourTable WHERE YourName='new name'
    insert into YourTable values ('new name',1)
    SET @y=@y+@@ROWCOUNT
end
print @y

This will capture requests for files like version, release, and README.md, etc. which should be treated either as endpoints, if defined (as in the case of /release), or as "not found."

in case it helps someone, my issue seems to be just because I was using a subfolder under my home directory, even though permissions seem correct and I don't have SELinux or anything like that. changing it to be under /var/www/something/something made it work.

(if I ever found the real cause, and remember this answer, I'll update it)

I have just experienced this issue in one of my MySQL db's and I looked at the phpMyAdmin answer here. However the best way I fixed it in phpMyAdmin was in the affected table, drop the id column and make a fresh/new id column (adding A-I -autoincrement-). This restored my table id correctly-simples! Hope that helps (no MySQL code needed-I hope to learn to use that but later!) anyone else with this problem.

If you are using ggplot2 to generate a figure, then a ggsave(file="name.eps") will also work.

For me it works a deleting "C:\ProgramData\Oracle\Java\javapath" in my system enviroment PATH variable

Edit: If you don't have that variable or it does not work you can directly delete or rename the directory "C:\ProgramData\Oracle\Java\javapath"

This worked for me by calculating size of string.
It is easy you need to echo the value you need to return and then store it like below

removechars(){
        var="some string.rtf"
        size=${#var}
        echo ${var:0:size-4}  
    }
    removechars
    var2=$?

some string

Current date is in yyyy-mm-dd format. You can convert it into yyyymmdd format using substring function:

select substr(current date,1,4)||substr(current date,6,2)||substr(currentdate,9,2)

You wrote the assignment backward: to assign a value (or an expression) to a variable you must have that variable at the left side of the assignment operator ( = in python )

subsequent_amount = invest(initial_amount,top_company(5,year,year+1))

var dateFormat = 'YYYY-DD-MM HH:mm:ss';
var testDateUtc = moment.utc('2015-01-30 10:00:00');
var localDate = testDateUtc.local();
console.log(localDate.format(dateFormat)); // 2015-30-01 02:00:00

1. Define your date format.
2. Create a moment object and set the UTC flag to true on the object.
3. Create a localized moment object converted from the original moment object.
4. Return a formatted string from the localized moment object.

See: http://momentjs.com/docs/#/manipulating/local/

Here is a more general solution:

int increment = 3;
for(int i = 0; i < theData.Length; i += increment)
{
   for(int j = 0; j < increment; j++)
   {
      if(i+j < theData.Length) {
         //theData[i + j] for the current index
      }
   }

}

Try the System.IO.DirectoryInfo class.

The sample from MSDN:

Imports System
Imports System.IO

Public Class Test
    Public Shared Sub Main()
        ' Specify the directories you want to manipulate.
        Dim di As DirectoryInfo = New DirectoryInfo("c:\MyDir")
        Try
            ' Determine whether the directory exists.
            If di.Exists Then
                ' Indicate that it already exists.
                Console.WriteLine("That path exists already.")
                Return
            End If

            ' Try to create the directory.
            di.Create()
            Console.WriteLine("The directory was created successfully.")

            ' Delete the directory.
            di.Delete()
            Console.WriteLine("The directory was deleted successfully.")

        Catch e As Exception
            Console.WriteLine("The process failed: {0}", e.ToString())
        End Try
    End Sub
End Class

As of the time of this writing, Swift natively supports comparing Dates with all comparison operators (i.e. <, <=, ==, >=, and >). You can also compare optional Dates but are limited to <, ==, and >. If you need to compare two optional dates using <= or >=, i.e.

let date1: Date? = ...
let date2: Date? = ...
if date1 >= date2 { ... }

You can overload the <= and >=operators to support optionals:

func <= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
    return lhs == rhs || lhs < rhs
}

func >= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
    return lhs == rhs || lhs > rhs
}

I had a similar issue where I couldn't connect to a database and tried the recommendations here.

At the end of the day this is what worked for me:

Used the SQL Server Configuration Manager tool to enable the TCP/IP and/or the Named Pipes protocols on the SQL Server client computer.

1. Click Start, point to All Programs, and click SQL Server Configuration Manager.
2. Click to expand SQL Server Network Configuration and then click Client Protocols.
3. Right-click the TCP/IP protocol and then click Enable.
4. Right-click the Named Pipes protocol and then click Enable.
5. Restart the SQL server service if prompted to do so.

I am still not sure why or when this was disabled.

Use getattr if you have an attribute in string form:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> param = 'name'
>>> getattr(u, param)
'John'

Otherwise use the dot .:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> u.name
'John'

An easy method, use ticks:

new DateTime((DateTime.Now - DateTime.Now.AddHours(-1.55)).Ticks).ToString("HH:mm:ss:fff")

This function will give you a date (Without Day / Month / Year)

From ?matrix: "A matrix is the special case of a two-dimensional 'array'." You can simply change the dimensions of the matrix/array.

Elts_int <- as.matrix(tmp_int)  # read.table returns a data.frame as Brandon noted
dim(Elts_int) <- (maxrow_int*maxcol_int,1)

To use alternate credentials for a single operation, use the --username and --password switches for svn.

To clear previously-saved credentials, delete ~/.subversion/auth. You'll be prompted for credentials the next time they're needed.

These settings are saved in the user's home directory, so if you're using a shared account on "this laptop", be careful - if you allow the client to save your credentials, someone can impersonate you. The first option I provided is the better way to go in this case. At least until you stop using shared accounts on computers, which you shouldn't be doing.

To change credentials you need to do:

• rm -rf ~/.subversion/auth
• svn up ( it'll ask you for new username & password )

This can be done in [N + log(N) - 2] time, which is slightly better than the loose upper bound of 2N (which can be thought of O(N) too).

The trick is to use binary recursive calls and "tennis tournament" algorithm. The winner (the largest number) will emerge after all the 'matches' (takes N-1 time), but if we record the 'players' of all the matches, and among them, group all the players that the winner has beaten, the second largest number will be the largest number in this group, i.e. the 'losers' group.

The size of this 'losers' group is log(N), and again, we can revoke the binary recursive calls to find the largest among the losers, which will take [log(N) - 1] time. Actually, we can just linearly scan the losers group to get the answer too, the time budget is the same.

Below is a sample python code:

def largest(L):
    global paris
    if len(L) == 1:
        return L[0]
    else:
        left = largest(L[:len(L)//2])
        right = largest(L[len(L)//2:])
        pairs.append((left, right))
        return max(left, right)

def second_largest(L):
    global pairs
    biggest = largest(L)
    second_L = [min(item) for item in pairs if biggest in item]

    return biggest, largest(second_L)  



if __name__ == "__main__":
    pairs = []
    # test array
    L = [2,-2,10,5,4,3,1,2,90,-98,53,45,23,56,432]    

    if len(L) == 0:
        first, second = None, None
    elif len(L) == 1:
        first, second = L[0], None
    else:
        first, second = second_largest(L)

    print('The largest number is: ' + str(first))
    print('The 2nd largest number is: ' + str(second))

The question revolves around how this keyword behaves in javascript. this behaves differently as below,

1. The value of this is usually determined by a function execution context.
2. In the global scope, this refers to the global object (the window object).
3. If strict mode is enabled for any function then the value of this will be undefined as in strict mode, global object refers to undefined in place of the window object.
4. The object that is standing before the dot is what this keyword will be bound to.
5. We can set the value of this explicitly with call(), bind(), and apply()
6. When the new keyword is used (a constructor), this is bound to the new object being created.
7. Arrow Functions don’t bind this — instead, this is bound lexically (i.e. based on the original context)

As most of the answers suggest, we can use Arrow function or bind() Method or Self var. I would quote a point about lambdas (Arrow function) from Google JavaScript Style Guide

Prefer using arrow functions over f.bind(this), and especially over goog.bind(f, this). Avoid writing const self = this. Arrow functions are particularly useful for callbacks, which sometimes pass unexpectedly additional arguments.

Google clearly recommends using lambdas rather than bind or const self = this

So the best solution would be to use lambdas as below,

function MyConstructor(data, transport) {
  this.data = data;
  transport.on('data', () => {
    alert(this.data);
  });
}

here is the answer for IE 8

AND IT WORKS for alpha to work in IE8 you have to use position atribute for that element like

position:relative or other.

http://www.codingforums.com/showthread.php?p=923730

you need javascript and some client side calculations: http://jsfiddle.net/omegaiori/NERE8/2/

you will need jquery to effectively achieve what you want. this function is very simple but very effective:

(function () {


    var heights = $("#wrapper").outerHeight(true);
    var outerHeights = $("#first").outerHeight(true);
    jQuery('#second').css('height', (heights - outerHeights) + "px");

})();

first it detects the wrapper height, as it is set to 100% it's different everytime (it depends on what screen you are landing). in the second step it gives the #second div the appropriate height subtracting from the wrapper height the #first div height. the result is the available height left in the wrapper div

Prior to Oracle 12C you cannot select from PL/SQL-defined tables, only from tables based on SQL types like this:

CREATE OR REPLACE TYPE exch_row AS OBJECT(
currency_cd VARCHAR2(9),
exch_rt_eur NUMBER,
exch_rt_usd NUMBER);


CREATE OR REPLACE TYPE exch_tbl AS TABLE OF exch_row;

In Oracle 12C it is now possible to select from PL/SQL tables that are defined in a package spec.

Try the vertical-align CSS property.

#box1 {
    width: 50px;
    height: 50px;
    background: #999;
    display: inline-block;
    vertical-align: top; /* here */
}

Apply it to #box3 too.

You could use x ** (1. / 3) to compute the (floating-point) cube root of x.

The slight subtlety here is that this works differently for negative numbers in Python 2 and 3. The following code, however, handles that:

def is_perfect_cube(x):
    x = abs(x)
    return int(round(x ** (1. / 3))) ** 3 == x

print(is_perfect_cube(63))
print(is_perfect_cube(64))
print(is_perfect_cube(65))
print(is_perfect_cube(-63))
print(is_perfect_cube(-64))
print(is_perfect_cube(-65))
print(is_perfect_cube(2146689000)) # no other currently posted solution
                                   # handles this correctly

This takes the cube root of x, rounds it to the nearest integer, raises to the third power, and finally checks whether the result equals x.

The reason to take the absolute value is to make the code work correctly for negative numbers across Python versions (Python 2 and 3 treat raising negative numbers to fractional powers differently).

2. Change your url same as your controller name.

e.g:

Your controller name is YourController

Your url must be:

http://example.com/index.php/YourController/method

Not be:

http://example.com/index.php/yourcontroller/method

I was having two .sh scripts to start and stop the digital ocean servers that I wanted to run from the Windows 10. What I did is:

• downloaded "Git for Windows" (from https://git-scm.com/download/win).
• installed Git
• to execute the .sh script just double-clicked the script file it started the execution of the script.

Now to run the script each time I just double-click the script

The way I know is easy.

var NSArray_variable = NSArray_Object[n]
var stringVarible = NSArray_variable as String

n is the inner position in the array This in SWIFT Language. It might work in Objective C

In my case none of the answers above solved my problem completely. I ended up using the (no-sandbox) mode, the connection with extended timeout period (driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capability, TimeSpan.FromMinutes(3));) and the page load timeout (driver.Manage().Timeouts().PageLoad.Add(System.TimeSpan.FromSeconds(30));) so now my code looks like this:

    public IWebDriver GetRemoteChromeDriver(string downloadPath)
    {
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.AddArguments(
            "start-maximized",
            "enable-automation",
            "--headless",
            "--no-sandbox", //this is the relevant other arguments came from solving other issues
            "--disable-infobars",
            "--disable-dev-shm-usage",
            "--disable-browser-side-navigation",
            "--disable-gpu",
            "--ignore-certificate-errors");
        capability = chromeOptions.ToCapabilities();

        SetRemoteWebDriver();
        SetImplicitlyWait();
        Thread.Sleep(TimeSpan.FromSeconds(2));
        return driver;
    }
    
    private void SetImplicitlyWait()
    {
        driver.Manage().Timeouts().PageLoad.Add(TimeSpan.FromSeconds(30));
    }


    private void SetRemoteWebDriver()
    {
        driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capability, TimeSpan.FromMinutes(3));
    }

But as I mentioned none of the above method solved my problem, I was continuously get the error, and multiple chromedriver.exe and chrome.exe processses were active (~10 of the chromedriver and ~50 of chrome).

So somewhere I read that after disposing the driver I should wait a few seconds before starting the next test, so I added the following line to dispose method:

    driver?.Quit();
    driver?.Dispose();
    Thread.Sleep(3000);

With this sleep modification I have no longer get the timeout error and there is no unnecessarily opened chromedriver.exe and chrome.exe processses.

I hope I helped someone who struggles with this issue for that long as I did.

For Windows, you can also whitelist your extension through Windows policies. The full steps are details in this answer, but there are quicker steps:

1. Create the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallWhitelist.
2. For each extension you want to whitelist, add a string value whose name should be a sequence number (starting at 1) and value is the extension ID.

For instance, in order to whitelist 2 extensions with ID aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa and bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb, create a string value with name 1 and value aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa, and a second value with name 2 and value bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb. This can be sum up by this registry file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallWhitelist]
"1"="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
"2"="bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb"

EDIT: actually, Chromium docs also indicate how to do it for other OS.

matches method performs matching of full line, i.e. it is equivalent to find() with '^abc$'. So, just use Pattern.compile("[a-zA-Z]").matcher(str).find() instead. Then fix your regex. As @user unknown mentioned your regex actually matches only one character. You probably should say [a-zA-Z]+

Your code seems right, check if you have fopen wrappers enabled (allow_url_fopen = On on php.ini)

Also, as mentioned by other answers, you should provide a properly encoded URI or encode it using urlencode() function. You should also check if there is any error fetching the XML string and if there is any parsing error, which you can output using libxml_get_errors() as follows:

<?php
if (($response_xml_data = file_get_contents($map_url))===false){
    echo "Error fetching XML\n";
} else {
   libxml_use_internal_errors(true);
   $data = simplexml_load_string($response_xml_data);
   if (!$data) {
       echo "Error loading XML\n";
       foreach(libxml_get_errors() as $error) {
           echo "\t", $error->message;
       }
   } else {
      print_r($data);
   }
}
?>

If the problem is you can't fetch the XML code maybe it's because you need to include some custom headers in your request, check how to use stream_context_create() to create a custom stream context for use when calling file_get_contents() on example 4 at http://php.net/manual/en/function.file-get-contents.php

I've been down this road and eventually opted for a hardware data scope that does non-instrusive in-line monitoring. The software solutions that I tried didn't work for me. If you had a spare PC you could probably build one, albeit rather bulky. This software data scope may work, as might this, but I haven't tried either.

F5 reloads the page from server, but it uses the browser's cache for page elements like scripts, image, CSS stylesheets, etc, etc. But Ctrl + F5, reloads the page from the server and also reloads its contents from server and doesn't use local cache at all.

So by pressing F5 on, say, the Yahoo homepage, it just reloads the main HTML frame and then loads all other elements like images from its cache. If a new element was added or changed then it gets it from the server. But Ctrl + F5 reloads everything from the server.

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

Can I recommend doing it this way, define your test like this:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
    TestPreperationExecutionListener.class
    })
@Transactional
@ActiveProfiles(profiles = "localtest")
@ContextConfiguration
public class TestContext {

  @Test
  public void testContext(){

  }

  @Configuration
  @PropertySource("classpath:/myprops.properties")
  @ImportResource({"classpath:context.xml" })
  public static class MyContextConfiguration{

  }
}

with the following content in myprops.properties file:

spring.profiles.active=localtest

With this your second properties file should get resolved:

META-INF/spring/config_${spring.profiles.active}.properties

To get a new line inside text-area, put an actual line-break there:

    <textarea cols='60' rows='8'>This is my statement one._x000D_
    This is my statement2</textarea>

Follow the steps:

1. Go psql shell
2. \c db_name
3. \i path_of_dump [eg:-C:/db_name.pgsql]

The easiest way is to add a type to the variable that is receiving the value, like this:

var value: string = (event.target as any).value;

Or you could cast the value property as well as event.target like this:

var value = ((event.target as any).value as string);

Edit:

Lastly, you can define what EventTarget.value is in a separate .d.ts file. However, the type will have to be compatible where it's used elsewhere, and you'll just end up using any again anyway.

globals.d.ts

interface EventTarget {
    value: any;
}

If you want this type of code to run in IE11 (which does not support much of ES6 at all), then you need to get a 3rd party promise library (like Bluebird), include that library and change your coding to use ES5 coding structures (no arrow functions, no let, etc...) so you can live within the limits of what older browsers support.

Or, you can use a transpiler (like Babel) to convert your ES6 code to ES5 code that will work in older browsers.

Here's a version of your code written in ES5 syntax with the Bluebird promise library:

<script src="https://cdnjs.cloudflare.com/ajax/libs/bluebird/3.3.4/bluebird.min.js"></script>

<script>

'use strict';

var promise = new Promise(function(resolve) {
    setTimeout(function() {
        resolve("result");
    }, 1000);
});

promise.then(function(result) {
    alert("Fulfilled: " + result);
}, function(error) {
    alert("Rejected: " + error);
});

</script>

The best bitmap encoder is the one you do not write yourself. The file format is a lot more involved, than one might expect. This is evidenced by the fact, that all proposed answers do not create a monochrome (1bpp) bitmap, but rather write out 24bpp files, that happen to only use 2 colors.

The following is a Windows-only solution, using the Windows Imaging Component. It doesn't rely on any external/3rd party libraries, other than what ships with Windows.

Like every C++ program, we need to include several header files. And link to Windowscodecs.lib while we're at it:

#include <Windows.h>
#include <comdef.h>
#include <comip.h>
#include <comutil.h>
#include <wincodec.h>

#include <vector>

#pragma comment(lib, "Windowscodecs.lib")

Next up, we declare our container (a vector, of vectors! Of bool!), and a few smart pointers for convenience:

using _com_util::CheckError;
using container = std::vector<std::vector<bool>>;

_COM_SMARTPTR_TYPEDEF(IWICImagingFactory, __uuidof(IWICImagingFactory));
_COM_SMARTPTR_TYPEDEF(IWICBitmapEncoder, __uuidof(IWICBitmapEncoder));
_COM_SMARTPTR_TYPEDEF(IWICBitmapFrameEncode, __uuidof(IWICBitmapFrameEncode));
_COM_SMARTPTR_TYPEDEF(IWICStream, __uuidof(IWICStream));
_COM_SMARTPTR_TYPEDEF(IWICPalette, __uuidof(IWICPalette));

With that all settled, we can jump right into the implementation. There's a bit of setup required to get a factory, an encoder, a frame, and get everything prepared:

void write_bitmap(wchar_t const* pathname, container const& data)
{
    // Create factory
    IWICImagingFactoryPtr sp_factory { nullptr };
    CheckError(sp_factory.CreateInstance(CLSID_WICImagingFactory, nullptr,
                                         CLSCTX_INPROC_SERVER));

    // Create encoder
    IWICBitmapEncoderPtr sp_encoder { nullptr };
    CheckError(sp_factory->CreateEncoder(GUID_ContainerFormatBmp, nullptr, &sp_encoder));

    // Create stream
    IWICStreamPtr sp_stream { nullptr };
    CheckError(sp_factory->CreateStream(&sp_stream));
    CheckError(sp_stream->InitializeFromFilename(pathname, GENERIC_WRITE));

    // Initialize encoder with stream
    CheckError(sp_encoder->Initialize(sp_stream, WICBitmapEncoderNoCache));

    // Create new frame
    IWICBitmapFrameEncodePtr sp_frame { nullptr };
    IPropertyBag2Ptr sp_properties { nullptr };
    CheckError(sp_encoder->CreateNewFrame(&sp_frame, &sp_properties));

    // Initialize frame with default properties
    CheckError(sp_frame->Initialize(sp_properties));

    // Set pixel format
    // SetPixelFormat() requires a pointer to non-const
    auto pf { GUID_WICPixelFormat1bppIndexed };
    CheckError(sp_frame->SetPixelFormat(&pf));
    if (!::IsEqualGUID(pf, GUID_WICPixelFormat1bppIndexed))
    {
        // Report unsupported pixel format
        CheckError(WINCODEC_ERR_UNSUPPORTEDPIXELFORMAT);
    }

    // Set size derived from data argument
    auto const width { static_cast<UINT>(data.size()) };
    auto const height { static_cast<UINT>(data[0].size()) };
    CheckError(sp_frame->SetSize(width, height));

    // Set palette on frame. This is required since we use an indexed pixel format.
    // Only GIF files support global palettes, so make sure to set it on the frame
    // rather than the encoder.
    IWICPalettePtr sp_palette { nullptr };
    CheckError(sp_factory->CreatePalette(&sp_palette));
    CheckError(sp_palette->InitializePredefined(WICBitmapPaletteTypeFixedBW, FALSE));
    CheckError(sp_frame->SetPalette(sp_palette));

At that point everything is set up, and we have a frame to dump our data into. For 1bpp files, every byte stores the information of 8 pixels. The left-most pixel is stored in the MSB, with pixels following all the way down to the right-most pixel stored in the LSB.

The code isn't entirely important; you'll be replacing that with whatever suits your needs, when you replace the data layout of your input anyway:

    // Write data to frame
    auto const stride { (width * 1 + 7) / 8 };
    auto const size { height * stride };
    std::vector<unsigned char> buffer(size, 127u);
    // Convert data to match required layout. Each byte stores 8 pixels, with the
    // MSB being the leftmost, the LSB the right-most.
    for (size_t x { 0 }; x < data.size(); ++x)
    {
        for (size_t y { 0 }; y < data[x].size(); ++y)
        {
            auto shift { x % 8 };
            auto mask { 0x80 >> shift };
            auto bit { mask * data[x][y] };
            auto& value { buffer[y * stride + x / 8] };
            value &= ~mask;
            value |= bit;
        }
    }
    CheckError(sp_frame->WritePixels(height, stride,
                                     static_cast<UINT>(buffer.size()), buffer.data()));

What's left is to commit the changes to the frame and the encoder, which will ultimately write the image file to disk:

    // Commit frame
    CheckError(sp_frame->Commit());

    // Commit image
    CheckError(sp_encoder->Commit());
}

This is a test program, writing out an image to a file passed as the first command-line argument:

#include <iostream>

int wmain(int argc, wchar_t* argv[])
try
{
    if (argc != 2)
    {
        return -1;
    }

    CheckError(::CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED));


    // Create 64x64 matrix
    container data(64, std::vector<bool>(64, false));
    // Fill with arrow pointing towards the upper left
    for (size_t i { 0 }; i < data.size(); ++i)
    {
        data[0][i] = true;
        data[i][0] = true;
        data[i][i] = true;
    }
    ::write_bitmap(argv[1], data);


    ::CoUninitialize();
}
catch (_com_error const& e)
{
    std::wcout << L"Error!\n" << L"  Message: " << e.ErrorMessage() << std::endl;
}

It produces the following image (true 1bpp, 574 bytes in size):

Follow the below steps:

1. Add to sending request header Content-Type field:

    axios.post(`/Order/`, orderId,
    {
        headers: {'Content-Type': 'application/json'}
    })
   

2. Every data (simple or complex type) sent with axios should be placed without any extra brackets (axios.post('/Order/', orderId, ...)).

WARNING! There is one exception for string type - stringify it before send (axios.post('/Order/', JSON.stringify(address), ...)).

3. Add method to controller:

   [HttpPost]
   public async Task<IActionResult> Post([FromBody]int orderId)
   {
       return Ok();
   }
   

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

For latest versions, use following steps:

1. Go to "msconfig" from Win+R
2. Go to Service tab
3. Uncheck both "Google Update Service" boxes.
4. Click OK and Restart computer to save changes.

I usually do:

git checkout .
git pull

In the project's root folder.

py2exe:

py2exe is a Python Distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation.

to read first line using bash, use read statement. eg

read -r firstline<file

firstline will be your variable (No need to assign to another)

from jQuery v1.6 use prop

to check that is checkd or not

$('input:radio').prop('checked') // will return true or false

and to make it checkd use

$("input").prop("checked", true);

I did the redistributable repair thing, but for me it worked after I installed Office365.

(for me it also was the last failing package on the list).

You can use the linux bash core utility split

split -b 1M -d  file.txt file 

Note that M or MB both are OK but size is different. MB is 1000 * 1000, M is 1024^2

If you want to separate by lines you can use -l parameter.

UPDATE

a=(`wc -l yourfile`) ; lines=`echo $(($a/12)) | bc -l` ; split -l $lines -d  file.txt file

Another solution as suggested by Kirill, you can do something like the following

split -n l/12 file.txt

Note that is l not one, split -n has a few options, like N, k/N, l/k/N, r/N, r/k/N.

I have created my own iterator to iterate over Outlook objects via python. The issue is that python tries to iterates starting with Index[0], but outlook expects for first item Index[1]... To make it more Ruby simple, there is below a helper class Oli with following methods:

.items() - yields a tuple(index, Item)...

.prop() - helping to introspect outlook object exposing available properties (methods and attributes)

from win32com.client import constants
from win32com.client.gencache import EnsureDispatch as Dispatch

outlook = Dispatch("Outlook.Application")
mapi = outlook.GetNamespace("MAPI")

class Oli():
    def __init__(self, outlook_object):
        self._obj = outlook_object

    def items(self):
        array_size = self._obj.Count
        for item_index in xrange(1,array_size+1):
            yield (item_index, self._obj[item_index])

    def prop(self):
        return sorted( self._obj._prop_map_get_.keys() )

for inx, folder in Oli(mapi.Folders).items():
    # iterate all Outlook folders (top level)
    print "-"*70
    print folder.Name

    for inx,subfolder in Oli(folder.Folders).items():
        print "(%i)" % inx, subfolder.Name,"=> ", subfolder

The usual rules should apply for how you send the request. If the request is to retrieve information (e.g. a partial search 'hint' result, or a new page to be displayed, etc...) you can use GET. If the data being sent is part of a request to change something (update a database, delete a record, etc..) then use POST.

Server-side, there's no reason to use the raw input, unless you want to grab the entire post/get data block in a single go. You can retrieve the specific information you want via the _GET/_POST arrays as usual. AJAX libraries such as MooTools/jQuery will handle the hard part of doing the actual AJAX calls and encoding form data into appropriate formats for you.

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

yes, and its quick and simple though very hidden:

binwidth=5
bin(x,width)=width*floor(x/width)

plot 'datafile' using (bin($1,binwidth)):(1.0) smooth freq with boxes

check out help smooth freq to see why the above makes a histogram

to deal with ranges just set the xrange variable.

Vertical align only works in some select cases. The easiest way to make it function is to set display: table in the parent element's CSS and display: table-cell; to the child element and then apply your vertical align attribute.

if your date filed is timestamp into database then this is the easy way to get record

$this->db->where('DATE(RecordDate) >=', date('Y-m-d',strtotime($startDate)));
$this->db->where('DATE(RecordDate) <=', date('Y-m-d',strtotime($endDate)));

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

Add the code

BasicConfigurator.configure();

in your static main class as below..

Note: add " \hadoop-2.7.1\share\hadoop\common\lib\commons-logging-1.1.3.jar & \hadoop-2.7.1\share\hadoop\common\lib\log4j-1.2.17.jar " as the external references

import org.apache.log4j.BasicConfigurator;

public class ViewCountDriver extends Configured implements Tool{

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

        BasicConfigurator.configure(); 

        int exitcode = ToolRunner.run(new ViewCountDriver(), args);
        System.exit(exitcode); 
    }
}

Based on Tim James answer and Fox32's comment, the following should check for nulls, with the assumption that two nulls are not equal.

function arrays_equal(a,b) { return !!a && !!b && !(a<b || b<a); }

> arrays_equal([1,2,3], [1,3,4])
false
> arrays_equal([1,2,3], [1,2,3])
true
> arrays_equal([1,3,4], [1,2,3])
false
> arrays_equal(null, [1,2,3])
false
> arrays_equal(null, null)
false

The above code fixed problem for most of the ppl but I still could not login. Finally I found this (line#9 in the above code needs to be changed)

$cfg['Servers'][$i]['AllowNoPassword'] = true;   <--- change this
$cfg['Servers'][$i]['AllowNoPassword'] = false;  <--- to this fixed the problem.

Note: there are other areas in localhost where you have to change the password manually. For example in "CD Collection" example. The password is hard coded there rather than picking it up from config.inc.php.

You need to be more explicit and add the start and end times as well, down to the milliseconds:

select * 
from xxx 
where dates between '2012-10-26 00:00:00.000' and '2012-10-27 23:59:59.997'

The database can very well interpret '2012-10-27' as '2012-10-27 00:00:00.000'.

This is working fine:

SELECT * FROM tablename ORDER BY position = 0, position ASC;

position
1 
2
3
0
0

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

Try to call your proc in this way:

DECLARE @UserIDout int

EXEC YOURPROC @EmailAddress = 'sdfds', @NickName = 'sdfdsfs', ..., @UserId = @UserIDout OUTPUT

SELECT @UserIDout 

A compromised solution is to fake bold with text-shadow, e.g:

text-shadow: 0 0 0.01px black;

For better comparison I created these examples:

Passing to text-shadow really low value for blur-radius will make the blurring effect not so apparent.

In general the more your repeat text-shadow the bolder your text will get but in the same time loosing original shape of the letters.

I should warn you that setting the blur-radius to fractions is not going to render the same in all browsers! Safari for example need bigger values to render it the same way Chrome will do.

• matplotlib is somewhat different from when the original answer was posted
• matplotlib.pyplot.text
• matplotlib.axes.Axes.text

import matplotlib.pyplot as plt

plt.figure(figsize=(6, 6))
plt.text(0.1, 0.9, 'text', size=15, color='purple')

# or 

fig, axe = plt.subplots(figsize=(6, 6))
axe.text(0.1, 0.9, 'text', size=15, color='purple')

Output of Both

• From matplotlib: Precise text layout
  • You can precisely layout text in data or axes coordinates.

import matplotlib.pyplot as plt

# Build a rectangle in axes coords

bottom, height = .25, .5
right = left + width
top = bottom + height
ax = plt.gca()
p = plt.Rectangle((left, bottom), width, height, fill=False)
p.set_transform(ax.transAxes)
p.set_clip_on(False)
ax.add_patch(p)


ax.text(left, bottom, 'left top',
        horizontalalignment='left',
        verticalalignment='top',

I use such kind of a Map population thanks to Java 9. In my honest opinion, this approach provides more readability to the code.

  public static void main(String[] args) {
    Map<Integer, Point2D.Double> map = Map.of(
        1, new Point2D.Double(1, 1),
        2, new Point2D.Double(2, 2),
        3, new Point2D.Double(3, 3),
        4, new Point2D.Double(4, 4));
    map.entrySet().forEach(System.out::println);
  }

XML-RPC is part of the Python standard library:

• Python 2: xmlrpclib and SimpleXMLRPCServer
• Python 3: xmlrpc (both client and server)

Amazingly now org.json now lets you put a byte[] object directly into a json and it remains readable. you can even send the resulting object over a websocket and it will be readable on the other side. but i am not sure yet if the size of the resulting object is bigger or smaller than if you were converting your byte array to base64, it would certainly be neat if it was smaller.

It seems to be incredibly hard to measure how much space such a json object takes up in java. if your json consists merely of strings it is easily achievable by simply stringifying it but with a bytearray inside it i fear it is not as straightforward.

stringifying our json in java replaces my bytearray for a 10 character string that looks like an id. doing the same in node.js replaces our byte[] for an unquoted value reading <Buffered Array: f0 ff ff ...> the length of the latter indicates a size increase of ~300% as would be expected

The solution for me was to restart the IDE. I suspect that a slow emulator was hiding from view, blocking installation on my device.

Like konsolebox suggested, the posters grep solution

grep -v -f file2 file1

actually works great (fast) if you simply add the -F option, to treat the patterns as fixed strings instead of regular expressions. I verified this on a pair of ~1000 line file lists I had to compare. With -F it took 0.031 s (real), while without it took 2.278 s (real), when redirecting grep output to wc -l.

These tests also included the -x switch, which are necessary part of the solution in order to ensure totally accuracy in cases where file2 contains lines which match part of, but not all of, one or more lines in file1.

So a solution that does not require the inputs to be sorted, is fast, flexible (case sensitivity, etc) is:

grep -F -x -v -f file2 file1

This doesn't work with all versions of grep, for example it fails in macOS, where a line in file 1 will be shown as not present in file 2, even though it is, if it matches another line that is a substring of it. Alternatively you can install GNU grep on macOS in order to use this solution.

To make a robust form, have it load in a useful state and use script to enhance its behaviour. In the following, the select has been replaced by radio buttons (makes life much easier for the user).

The "yes" option is checked by default and the select is enabled. If the user checks either radio button, the select is enabled or disabled accordingly.

<form onclick="this.mySelect1.disabled = this.becomeMember[1].checked;" ... >
  <input type="radio" name="becomeMember" checked>Yes<br>
  <input type="radio" name="becomeMember">No<br>

  <select id="mySelect1">
    <option>Dep1
    <option>Dep2
    <option>Dep3
    <option>Dep4
  </select>
  ...
</form> 

If you'd like to use dynamic mapping, and don't want to clutter up your model with attributes, this approach worked for me

Usage:

var settings = new JsonSerializerSettings();
settings.DateFormatString = "YYYY-MM-DD";
settings.ContractResolver = new CustomContractResolver();
this.DataContext = JsonConvert.DeserializeObject<CountResponse>(jsonString, settings);

Logic:

public class CustomContractResolver : DefaultContractResolver
{
    private Dictionary<string, string> PropertyMappings { get; set; }

    public CustomContractResolver()
    {
        this.PropertyMappings = new Dictionary<string, string> 
        {
            {"Meta", "meta"},
            {"LastUpdated", "last_updated"},
            {"Disclaimer", "disclaimer"},
            {"License", "license"},
            {"CountResults", "results"},
            {"Term", "term"},
            {"Count", "count"},
        };
    }

    protected override string ResolvePropertyName(string propertyName)
    {
        string resolvedName = null;
        var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
        return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
    }
}

This code is equivalent, shorter, and more readable:

int8_t strcmp (const uint8_t* s1, const uint8_t* s2)
{
    while( (*s1!='\0') && (*s1==*s2) ){
        s1++; 
        s2++;
    }

    return (int8_t)*s1 - (int8_t)*s2;
}

We only need to test for end of s1, because if we reach the end of s2 before end of s1, the loop will terminate (since *s2 != *s1).

The return expression calculates the correct value in every case, provided we are only using 7-bit (pure ASCII) characters. Careful thought is needed to produce correct code for 8-bit characters, because of the risk of integer overflow.

I needed a way to deal with all caps words, and I liked Ricky AH's solution, but I took it a step further to implement it as an extension method. This avoids the step of having to create your array of chars then call ToArray on it explicitly every time - so you can just call it on the string, like so:

usage:

string newString = oldString.ToProper();

code:

public static class StringExtensions
{
    public static string ToProper(this string s)
    {
        return new string(s.CharsToTitleCase().ToArray());
    }

    public static IEnumerable<char> CharsToTitleCase(this string s)
    {
        bool newWord = true;
        foreach (char c in s)
        {
            if (newWord) { yield return Char.ToUpper(c); newWord = false; }
            else yield return Char.ToLower(c);
            if (c == ' ') newWord = true;
        }
    }

}

Since I just learned about this cool thing(indexing into lists from within a format string) I'm adding to this old question.

s = '{x[0]} BLAH {x[1]} FOO {x[2]} BAR'
x = ['1', '2', '3']
print (s.format (x=x))

Output:

1 BLAH 2 FOO 3 BAR

However, I still haven't figured out how to do slicing(inside of the format string '"{x[2:4]}".format...,) and would love to figure it out if anyone has an idea, however I suspect that you simply cannot do that.

To learn how to make a pull request I just followed two separate help pages on Github (linked below as bullet points). The following command line commands are for Part 1. Part 2, the actual pull request, is done entirely on Github's website.

$ git clone https://github.com/tim-peterson/dwolla-php.git
$ cd dwolla-php
$ git remote add upstream https://github.com/Dwolla/dwolla-php.git
$ git fetch upstream
// make your changes to this newly cloned, local repo 
$ git add .
$ git commit -m '1st commit to dwolla'
$ git push origin master

• Part 1: fork someone's repo: https://help.github.com/articles/fork-a-repo

  1. click the 'fork' button on the repo you want to contribute to, in this case: Dwolla's PHP repo (Dwolla/dwolla-php)
  2. get the URL for your newly created fork, in this case: https://github.com/tim-peterson/dwolla-php.git (tim-peterson/dwolla-php)
  3. type the git clone->cd dwolla-php->git remote->git fetch sequence above to clone your fork somewhere in your computer (i.e., "copy/paste" it to, in this case: third_party TimPeterson$) and sync it with the master repo (Dwolla/dwolla-php)
  4. make your changes to your local repo
  5. type the git add->git commit->git push sequence above to push your changes to the remote repo, i.e., your fork on Github (tim-peterson/dwolla-php)

• Part 2: make pull-request: https://help.github.com/articles/using-pull-requests

  6. go to your fork's webpage on Github (https://github.com/tim-peterson/dwolla-php)
  7. click 'pull-request' button
  8. give pull-request a name, fill in details of what changes you made, click submit button.
  9. you're done!!

showInventory(player);     // I get the error here.

void showInventory(player& obj) {   // By Johnny :D

this means that player is an datatype and showInventory expect an referance to an variable of type player.

so the correct code will be

  void showInventory(player& obj) {   // By Johnny :D
    for(int i = 0; i < 20; i++) {
        std::cout << "\nINVENTORY:\n" + obj.getItem(i);
        i++;
        std::cout << "\t\t\t" + obj.getItem(i) + "\n";
        i++;
    }
    }

players myPlayers[10];

    std::string toDo() //BY KEATON
    {
    std::string commands[5] =   // This is the valid list of commands.
        {"help", "inv"};

    std::string ans;
    std::cout << "\nWhat do you wish to do?\n>> ";
    std::cin >> ans;

    if(ans == commands[0]) {
        helpMenu();
        return NULL;
    }
    else if(ans == commands[1]) {
        showInventory(myPlayers[0]);     // or any other index,also is not necessary to have an array
        return NULL;
    }

}

One technique, suggested by this article, would be to do this:

Here is another way to do it if you want to use ViewData:

@Html.Partial("~/PathToYourView.cshtml", null, new ViewDataDictionary { { "VariableName", "some value" } })

And to retrieve the passed in values:

@{
    string valuePassedIn = this.ViewData.ContainsKey("VariableName") ? this.ViewData["VariableName"].ToString() : string.Empty;
}

Try This Code. here we have two longitude and latitude values and selected_location.distanceTo(near_locations) function returns the distance between those places in meters.

Location selected_location = new Location("locationA");
            selected_location.setLatitude(17.372102);
            selected_location.setLongitude(78.484196);
Location near_locations = new Location("locationB");
            near_locations.setLatitude(17.375775);
            near_locations.setLongitude(78.469218);
double distance = selected_location.distanceTo(near_locations);

here "distance" is distance between locationA & locationB (in Meters)

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

Simply find all the selected <option> tags within your <select> and remove the selected attribute:

$("#my_select option:selected").removeAttr("selected");

As of jQuery 1.6, you should use .prop instead of removing the attribute:

$("#my_select option:selected").prop("selected", false);

Here is a numpy version of Sieve of Eratosthenes having both okay complexity (lower than sorting an array of length n) and vectorization.

import numpy as np 
def generate_primes(n):
    is_prime = np.ones(n+1,dtype=bool)
    is_prime[0:2] = False
    for i in range(int(n**0.5)+1):
        if is_prime[i]:
            is_prime[i*2::i]=False
    return np.where(is_prime)[0]

Timings:

import time    
for i in range(2,10):
    timer =time.time()
    generate_primes(10**i)
    print('n = 10^',i,' time =', round(time.time()-timer,6))

>> n = 10^ 2  time = 5.6e-05
>> n = 10^ 3  time = 6.4e-05
>> n = 10^ 4  time = 0.000114
>> n = 10^ 5  time = 0.000593
>> n = 10^ 6  time = 0.00467
>> n = 10^ 7  time = 0.177758
>> n = 10^ 8  time = 1.701312
>> n = 10^ 9  time = 19.322478

Try this code:

final File f = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());

replace 'MyClass' with your class containing the main method.

Alternatively you can also use

System.getProperty("java.class.path")

Above mentioned System property provides

Path used to find directories and JAR archives containing class files. Elements of the class path are separated by a platform-specific character specified in the path.separator property.

If you are searching by the fieldname1 value, try this:

var r = exitDictionary
   .Select(i => i.Value).Cast<Dictionary<string, object>>()
   .Where(d => d.ContainsKey("fieldname1"))
   .Select(d => d["fieldname1"]).Cast<List<Dictionary<string, string>>>()
   .SelectMany(d1 => 
       d1
        .Where(d => d.ContainsKey("valueTitle"))
        .Select(d => d["valueTitle"])
        .Where(v => v != null)).ToList();

If you are looking by the type of the value in the subDictionary (Dictionary<string, object> explicitly), you may do this:

var r = exitDictionary
   .Select(i => i.Value).Cast<Dictionary<string, object>>()
   .SelectMany(d=>d.Values)
   .OfType<List<Dictionary<string, string>>>()
   .SelectMany(d1 => 
       d1
        .Where(d => d.ContainsKey("valueTitle"))
        .Select(d => d["valueTitle"])
        .Where(v => v != null)).ToList();

Both alternatives will return:

title1
title2
title3
title1
title2

This works fine:

os.path.join(dir_name, base_filename + "." + filename_suffix)

Keep in mind that os.path.join() exists only because different operating systems use different path separator characters. It smooths over that difference so cross-platform code doesn't have to be cluttered with special cases for each OS. There is no need to do this for file name "extensions" (see footnote) because they are always connected to the rest of the name with a dot character, on every OS.

If using a function anyway makes you feel better (and you like needlessly complicating your code), you can do this:

os.path.join(dir_name, '.'.join((base_filename, filename_suffix)))

If you prefer to keep your code clean, simply include the dot in the suffix:

suffix = '.pdf'
os.path.join(dir_name, base_filename + suffix)

That approach also happens to be compatible with the suffix conventions in pathlib, which was introduced in python 3.4 after this question was asked. New code that doesn't require backward compatibility can do this:

suffix = '.pdf'
pathlib.PurePath(dir_name, base_filename + suffix)

You might prefer the shorter Path instead of PurePath if you're only handling paths for the local OS.

Warning: Do not use pathlib's with_suffix() for this purpose. That method will corrupt base_filename if it ever contains a dot.

Footnote: Outside of Micorsoft operating systems, there is no such thing as a file name "extension". Its presence on Windows comes from MS-DOS and FAT, which borrowed it from CP/M, which has been dead for decades. That dot-plus-three-letters that many of us are accustomed to seeing is just part of the file name on every other modern OS, where it has no built-in meaning.

This problem was solved for me by running VMware workstation as Windows administrator. From the start menu right click on the VMware workstation, then select "Run as Administrator"

I think the response of aaron can be enhanced for URL that contains variables:

var sdk = require('postman-collection');      

const testURL=pm.environment.values.substitute(pm.request.url, null, false);

const objURL=new sdk.Url(testURL);

console.log("clearing cookies for: "+testURL);

const jar = pm.cookies.jar();

jar.clear(objURL, function (error) {
  // error - <Error>
  if(error)
  console.log("Error clearing cookies: "+error);
});

The difference between a shared project and a class library is that the latter is compiled and the unit of reuse is the assembly.

Whereas with the former, the unit of reuse is the source code, and the shared code is incorporated into each assembly that references the shared project.

This can be useful when you want to create separate assemblies that target specific platforms but still have code that should be shared.

See also here:

The shared project reference shows up under the References node in the Solution Explorer, but the code and assets in the shared project are treated as if they were files linked into the main project.

In previous versions of Visual Studio¹, you could share source code between projects by Add -> Existing Item and then choosing to Link. But this was kind of clunky and each separate source file had to be selected individually. With the move to supporting multiple disparate platforms (iOS, Android, etc), they decided to make it easier to share source between projects by adding the concept of Shared Projects.

¹ This question and my answer (up until now) suggest that Shared Projects was a new feature in Visual Studio 2015. In fact, they made their debut in Visual Studio 2013 Update 2

Another option is to format your axis tick labels with commas is by using the package scales, and add

 scale_y_continuous(name="Fluorescent intensity/arbitrary units", labels = comma)

to your ggplot statement.

If you don't want to load the package, use:

scale_y_continuous(name="Fluorescent intensity/arbitrary units", labels = scales::comma)

In PowerShell 5 and PowerShell 5 ISE, it is also possible to use just Shift + Enter for multiline editing (instead of standard backticks ` at the end of each line):

PS> &"C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" # Shift+Enter
>>> -verb:sync # Shift+Enter
>>> -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" # Shift+Enter
>>> -dest:contentPath="c:\websites\xxx\wwwroot,computerName=192.168.1.1,username=administrator,password=xxx"

You can also convert your array to a list and call remove on the list. You can then convert back to your array.

int[] numbers = {1, 3, 4, 9, 2};
var numbersList = numbers.ToList();
numbersList.Remove(4);

I would like to recommend flask-empty at GitHub.

It provides an easy way to understand Blueprints, multiple views and extensions.

At the first site is a dropdown field to select the language of phpmyadmin.

In the config.inc.php you can set:

$cfg['Lang'] = '';

More details you can find in the documentation: http://www.phpmyadmin.net/documentation/

As a minor addition to this thread, in general you want to avoid using the views that begin with sys.sys* as Microsoft is only including them for backwards compatibility. For your code, you should probably use sys.server_principals. This is assuming you are using SQL 2005 or greater.

I ran into this problem when my insert value fields contained tabs and spaces that were not obvious to the naked eye. I had created my value list in Excel, copied, and pasted it to SQL, and run queries to find non-matches on my FK fields.

The match queries did not detect there were tabs and spaces in my FK field, but the INSERT did recognize them and it continued to generate the error.

I tested again by copying the content of the FK field in one record and pasting it into the insert query. When that record also failed, I looked closer at the data and finally detected the tabs/spaces.

Once I cleaned removed tabs/spaces, my issue was resolved. Hope this helps someone!

This can now be done as of docker-compose v2+ as part of the build object;

docker-compose.yml

version: '2'
services:
    my_image_name:
        build:
            context: . #current dir as build context
            args:
                var1: 1
                var2: c

See the docker compose docs.

In the above example "var1" and "var2" will be sent to the build environment.

Note: any env variables (specified by using the environment block) which have the same name as args variable(s) will override that variable.

if you have this already and use jquery this will be your answer:

$($(this)[0].selectedOptions[0]).text()

You probably need to use a TableModel (Oracle's tutorial here)

How implements your own TableModel

public class FootballClubTableModel extends AbstractTableModel {
  private List<FootballClub> clubs ;
  private String[] columns ; 

  public FootBallClubTableModel(List<FootballClub> aClubList){
    super();
    clubs = aClubList ;
    columns = new String[]{"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};
  }

  // Number of column of your table
  public int getColumnCount() {
    return columns.length ;
  }

  // Number of row of your table
  public int getRowsCount() {
    return clubs.size();
  }

  // The object to render in a cell
  public Object getValueAt(int row, int col) {
    FootballClub club = clubs.get(row);
    switch(col) {
      case 0: return club.getPosition();
      // to complete here...
      default: return null;
    }
  }

  // Optional, the name of your column
  public String getColumnName(int col) {
    return columns[col] ;
  }

}

You maybe need to override anothers methods of TableModel, depends on what you want to do, but here is the essential methods to understand and implements :)
Use it like this

List<FootballClub> clubs = getFootballClub();
TableModel model = new FootballClubTableModel(clubs);
JTable table = new JTable(model);

Hope it help !

This example uses Bash's built-in getopts command and is from the Google Shell Style Guide:

a_flag=''
b_flag=''
files=''
verbose='false'

print_usage() {
  printf "Usage: ..."
}

while getopts 'abf:v' flag; do
  case "${flag}" in
    a) a_flag='true' ;;
    b) b_flag='true' ;;
    f) files="${OPTARG}" ;;
    v) verbose='true' ;;
    *) print_usage
       exit 1 ;;
  esac
done

Note: If a character is followed by a colon (e.g. f:), that option is expected to have an argument.

Example usage: ./script -v -a -b -f filename

Using getopts has several advantages over the accepted answer:

• the while condition is a lot more readable and shows what the accepted options are
• cleaner code; no counting the number of parameters and shifting
• you can join options (e.g. -a -b -c ? -abc)

However, a big disadvantage is that it doesn't support long options, only single-character options.

Use Regular Expression to match for only letters. It's also good to have knowledge about, if you ever need to do something more complicated, like make sure it's a certain count of numbers.

function checkInp()
{
    var x=document.forms["myForm"]["age"].value;
    var regex=/^[a-zA-Z]+$/;
    if (!x.match(regex))
    {
        alert("Must input string");
        return false;
    }
}

Even better would be to deny anything but numbers:

function checkInp()
{
    var x=document.forms["myForm"]["age"].value;
    var regex=/^[0-9]+$/;
    if (x.match(regex))
    {
        alert("Must input numbers");
        return false;
    }
}

You have to make the UL inside the div behave like a block. Try adding

.navigation ul {
     display: inline-block;
}

size: PropTypes.oneOfType([
  PropTypes.string,
  PropTypes.number
]),

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

If by "current date" you are thinking about "today", then this trick may work for you:

> new Date(3600000*Math.floor(Date.now()/3600000))
2020-05-07T07:00:00.000Z

This way you are getting today Date instance with time 0:00:00.

The principle of operation is very simple: we take the current timestamp and divide it for 1 day expressed in milliseconds. We will get a fraction. By using Math.floor, we get rid of the fraction, so we get an integer. Now if we multiply it back by one day (again - in milliseconds), we get a date timestamp with the time exactly at the beginning of the day.

> now = Date.now()
1588837459929
> daysInMs = now/3600000
441343.73886916664
> justDays = Math.floor(daysInMs)
441343
> today = justDays*3600000
1588834800000
> new Date(today)
2020-05-07T07:00:00.000Z

Clean and simple.

You could also use bc

hour=8
result=$(echo "$hour + 1" | bc)
echo $result
9

Android Studio now has learned to work with GitHub fork repositories (you don't even have to add "upstream" remote repository by console command).

Open menu VCS ? Git

And pay attention to the two last popup menu items:

• Rebase my GitHub fork

• Create Pull Request

Try them. I use the first one to synchronize my local repository. Anyway the branches from the parent remote repository ("upstream") will be accessible in Android Studio after you click "Rebase my GitHub fork", and you will be able to operate with them easily.

(I use Android Studio 3.0 with "Git integration" and "GitHub" plugins.)

A Stack is a LIFO (Last In First Out) data structure. The push and pop operations are simple. Push puts something on the stack, pop takes something off. You put onto the top, and take off the top, to preserve the LIFO order.

edit -- corrected from FIFO, to LIFO. Facepalm!

to illustrate, you start with a blank stack

|

then you push 'x'

| 'x'

then you push 'y'

| 'x' 'y'

then you pop

| 'x'

See my comment above, and I believe you have to use NSInvocation when there is more than one parameter

The SQL Server password hashing algorithm:

hashBytes = 0x0100 | fourByteSalt | SHA1(utf16EncodedPassword+fourByteSalt)

For example, to hash the password "correct horse battery staple". First we generate some random salt:

fourByteSalt = 0x9A664D79;

And then hash the password (encoded in UTF-16) along with the salt:

 SHA1("correct horse battery staple" + 0x9A66D79);
=SHA1(0x63006F007200720065006300740020006200610074007400650072007900200068006F00720073006500200073007400610070006C006500 0x9A66D79)
=0x6EDB2FA35E3B8FAB4DBA2FFB62F5426B67FE54A3

The value stored in the syslogins table is the concatenation of:

[header] + [salt] + [hash]
0x0100 9A664D79 6EDB2FA35E3B8FAB4DBA2FFB62F5426B67FE54A3

Which you can see in SQL Server:

SELECT 
   name, CAST(password AS varbinary(max)) AS PasswordHash
FROM sys.syslogins
WHERE name = 'sa'

name  PasswordHash
====  ======================================================
sa    0x01009A664D796EDB2FA35E3B8FAB4DBA2FFB62F5426B67FE54A3

• Version header: 0100
• Salt (four bytes): 9A664D79
• Hash: 6EDB2FA35E3B8FAB4DBA2FFB62F5426B67FE54A3 (SHA-1 is 20 bytes; 160 bits)

Validation

You validate a password by performing the same hash:

• grab the salt from the saved PasswordHash: 0x9A664D79

and perform the hash again:

SHA1("correct horse battery staple" + 0x9A66D79);

which will come out to the same hash, and you know the password is correct.

What once was good, but now is weak

The hashing algorithm introduced with SQL Server 7, in 1999, was good for 1999.

• It is good that the password hash salted.
• It is good to append the salt to the password, rather than prepend it.

But today it is out-dated. It only runs the hash once, where it should run it a few thousand times, in order to thwart brute-force attacks.

In fact, Microsoft's Baseline Security Analyzer will, as part of it's checks, attempt to bruteforce passwords. If it guesses any, it reports the passwords as weak. And it does get some.

Brute Forcing

To help you test some passwords:

DECLARE @hash varbinary(max)
SET @hash = 0x01009A664D796EDB2FA35E3B8FAB4DBA2FFB62F5426B67FE54A3
--Header: 0x0100
--Salt:   0x9A664D79
--Hash:   0x6EDB2FA35E3B8FAB4DBA2FFB62F5426B67FE54A3

DECLARE @password nvarchar(max)
SET @password = 'password'

SELECT
    @password AS CandidatePassword,
    @hash AS PasswordHash,

    --Header
    0x0100
    +
    --Salt
    CONVERT(VARBINARY(4), SUBSTRING(CONVERT(NVARCHAR(MAX), @hash), 2, 2))
    +
    --SHA1 of Password + Salt
    HASHBYTES('SHA1', @password + SUBSTRING(CONVERT(NVARCHAR(MAX), @hash), 2, 2))

SQL Server 2012 and SHA-512

Starting with SQL Server 2012, Microsoft switched to using SHA-2 512-bit:

hashBytes = 0x0200 | fourByteSalt | SHA512(utf16EncodedPassword+fourByteSalt)

Changing the version prefix to 0x0200:

SELECT 
   name, CAST(password AS varbinary(max)) AS PasswordHash
FROM sys.syslogins

name  PasswordHash
----  --------------------------------
xkcd  0x02006A80BA229556EB280AA7818FAF63A0DA8D6B7B120C6760F0EB0CB5BB320A961B04BD0836 0C0E8CC4C326220501147D6A9ABD2A006B33DEC99FCF1A822393FC66226B7D38

• Version: 0200 (SHA-2 256-bit)
• Salt: 6A80BA22
• Hash (64 bytes): 9556EB280AA7818FAF63A0DA8D6B7B120C6760F0EB0CB5BB320A961B04BD0836 0C0E8CC4C326220501147D6A9ABD2A006B33DEC99FCF1A822393FC66226B7D38

This means we hash the UTF-16 encoded password, with the salt suffix:

• SHA512("correct horse battery staple"+6A80BA22)
• SHA512(63006f0072007200650063007400200068006f0072007300650020006200610074007400650072007900200073007400610070006c006500 + 6A80BA22)
• 9556EB280AA7818FAF63A0DA8D6B7B120C6760F0EB0CB5BB320A961B04BD0836 0C0E8CC4C326220501147D6A9ABD2A006B33DEC99FCF1A822393FC66226B7D38

import os def parent_directory(): # Create a relative path to the parent # of the current working directory path = os.getcwd() parent = os.path.dirname(path)

In android 2.2 you could do the following.

Create an xml drawable such as /res/drawable/textlines.xml and assign this as a TextView's background property.

<TextView
android:text="My text with lines above and below"
android:background="@drawable/textlines"
/>

/res/drawable/textlines.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
      <shape 
        android:shape="rectangle">
            <stroke android:width="1dp" android:color="#FF000000" />
            <solid android:color="#FFDDDDDD" />

        </shape>
   </item>

   <item android:top="1dp" android:bottom="1dp"> 
      <shape 
        android:shape="rectangle">
            <stroke android:width="1dp" android:color="#FFDDDDDD" />
            <solid android:color="#00000000" />
        </shape>
   </item>

</layer-list>

The down side to this is that you have to specify an opaque background colour, as transparencies won't work. (At least i thought they did but i was mistaken). In the above example you can see that the solid colour of the first shape #FFdddddd is copied in the 2nd shapes stroke colour.

POD is the official way to do multi line comments in Perl,

• see Multi-line comments in perl code and
• Better ways to make multi-line comments in Perl for more detail.

From faq.perl.org[perlfaq7]

• How can I comment out a large block of Perl code?

The quick-and-dirty way to comment out more than one line of Perl is to surround those lines with Pod directives. You have to put these directives at the beginning of the line and somewhere where Perl expects a new statement (so not in the middle of statements like the # comments). You end the comment with =cut, ending the Pod section:

=pod

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=cut

The quick-and-dirty method only works well when you don't plan to leave the commented code in the source. If a Pod parser comes along, your multiline comment is going to show up in the Pod translation. A better way hides it from Pod parsers as well.

The =begin directive can mark a section for a particular purpose. If the Pod parser doesn't want to handle it, it just ignores it. Label the comments with comment. End the comment using =end with the same label. You still need the =cut to go back to Perl code from the Pod comment:

=begin comment

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=end comment

=cut

Just adding to the answers already given, the solution using the string "nunique" seems much faster, tested here on ~21M rows dataframe, then grouped to ~2M

%time _=g.agg({"id": lambda x: x.nunique()})
CPU times: user 3min 3s, sys: 2.94 s, total: 3min 6s
Wall time: 3min 20s

%time _=g.agg({"id": pd.Series.nunique})
CPU times: user 3min 2s, sys: 2.44 s, total: 3min 4s
Wall time: 3min 18s

%time _=g.agg({"id": "nunique"})
CPU times: user 14 s, sys: 4.76 s, total: 18.8 s
Wall time: 24.4 s

If you're using @ConfigurationProperties with Spring Boot 2 to inject maps with keys that contain colons then you need an additional level of escaping using square brackets inside the quotes because spring only allows alphanumeric and '-' characters, stripping out the rest. Your new key would look like this:

"[8.11.32.120:8000]": GoogleMapsKeyforThisDomain

See this github issue for reference.

We have this problem with one database we don't control and it requried another solution (The ones listed here didn't work). For mine I needed:

-Djdk.tls.client.protocols="TLSv1,TLSv1.1"

I think in my case it had to do with forcing a certain order.

I'm using windows OS, I tried all solutions above and none of them work.

Finally, I install Tesseract-OCR on D drive(Where I run my python script from) instead of C drive and it works.

So, if you are using windows, run your python script in the same drive as your Tesseract-OCR.

you can use pass inside if statement.

I would put an absolutely positioned, z-index: 100; span (or spans) with the background: url("myImageWithRoundedCorners.jpg"); set on it inside the #mainWrapperDivWithBGImage .

TypeScript uses '<>' to surround casts, so the above becomes:

var script = <HTMLScriptElement>document.getElementsByName("script")[0];

However, unfortunately you cannot do:

var script = (<HTMLScriptElement[]>document.getElementsByName(id))[0];

You get the error

Cannot convert 'NodeList' to 'HTMLScriptElement[]'

But you can do :

(<HTMLScriptElement[]><any>document.getElementsByName(id))[0];

By design the body content in ASP.NET Web API is treated as forward-only stream that can be read only once.

The first read in your case is being done when Web API is binding your model, after that the Request.Content will not return anything.

You can remove the contact from your action parameters, get the content and deserialize it manually into object (for example with Json.NET):

[HttpPut]
public HttpResponseMessage Put(int accountId)
{
    HttpContent requestContent = Request.Content;
    string jsonContent = requestContent.ReadAsStringAsync().Result;
    CONTACT contact = JsonConvert.DeserializeObject<CONTACT>(jsonContent);
    ...
}

That should do the trick (assuming that accountId is URL parameter so it will not be treated as content read).

LIBRARY_PATH is used by gcc before compilation to search directories containing static and shared libraries that need to be linked to your program.

LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it has been successfully compiled and linked.

EDIT: As pointed below, your libraries can be static or shared. If it is static then the code is copied over into your program and you don't need to search for the library after your program is compiled and linked. If your library is shared then it needs to be dynamically linked to your program and that's when LD_LIBRARY_PATH comes into play.

You can use StringEx. It extends String with string-to-number conversions including toDouble().

extension String {
    func toDouble() -> Double?
}

It verifies the string and fails if it can't be converted to double.

Example:

import StringEx

let str = "123.45678"
if let num = str.toDouble() {
    println("Number: \(num)")
} else {
    println("Invalid string")
}

The emptyMap method of the Collections class.

Make the keydown even call multiple functions, with each function checking for a specific key and responding appropriately.

document.keydown = function (key) {

    checkKey("x");
    checkKey("y");
};

            this.http
            .post('/project/test/export',
                    somevalue,options)
              .subscribe(data => {

                  var mediaType = 'application/vnd.ms-excel';
                  let blob: Blob = data.blob();
                    window['saveAs'](blob, 'sample.xls');

                });

This will give you xls file format. If you want other formats change the mediatype and file name with right extension.

For me the easiest way... Create an public EditText, for Example "myEditText1"

public EditText myEditText1;

Then, connect it with the EditText which should get cleared

myEditText1 = (EditText) findViewById(R.id.numberfield);

After that, create an void which reacts to an click to the EditText an let it clear the Text inside it when its Focused, for Example

@OnClick(R.id.numberfield)
        void textGone(){
            if (myEditText1.isFocused()){
                myEditText1.setText("");

        }
    }

Hope i could help you, Have a nice Day everyone

Your best bet would be using the RFC defined mime-type audio/mpeg.

Check if any service is listening on port 5037, and kill it. You can use lsof for this:

$ lsof -i :5037
$ kill <PID Process>

Then try

$ adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

This solved my problem.

Click on the error message displaying "Unbound classpath container: 'JRE System Library[jdk1.5.0_08]", left click anyd choose quick fix. Under quick, list of possible options will get displated. Choose replace library. Choose the library you installed. Your good to go.

Defining array with multiple types in TypeScript

Use a union type (string|number)[] demo:

const foo: (string|number)[] = [ 1, "message" ];

I have an array of the form: [ 1, "message" ].

If you are sure that there are always only two elements [number, string] then you can declare it as a tuple:

const foo: [number, string] = [ 1, "message" ];

Straightforward and easy solution is:

docker build .
=> ....
=> Successfully built a3e628814c67
docker run -p 3000:3000 a3e628814c67

3000 - can be any port

a3e628814c68 - hash result given by success build command

NOTE: you should be within directory that contains Dockerfile.

As of November 2018 the package autocomplete-python offers this functionality with this key combo:

Ctrl+Alt+G

with mouse cursor on the function call.

What you need to know in one place:

• For environment variables to override any config settings, they must be prefixed with ASPNETCORE_.
• If you want to match child nodes in your JSON config, use : as a separater. If the platform doesn't allow colons in environment variable keys, use __ instead.
• You want your settings to end up in ApplicationHost.config. Using the IIS Configuration Editor will cause your inputs to be written to the application's Web.config -- and will be overwritten with the next deployment!

• For modifying ApplicationHost.config, you want to use appcmd.exe to make sure your modifications are consistent. Example: %systemroot%\system32\inetsrv\appcmd.exe set config "Default Web Site/MyVirtualDir" -section:system.webServer/aspNetCore /+"environmentVariables.[name='ASPNETCORE_AWS:Region',value='eu-central-1']" /commit:site

• Characters that are not URL-safe can be escaped as Unicode, like %u007b for left curly bracket.

• To list your current settings (combined with values from Web.config): %systemroot%\system32\inetsrv\appcmd.exe list config "Default Web Site/MyVirtualDir" -section:system.webServer/aspNetCore
• If you run the command to set a configuration key multiple times for the same key, it will be added multiple times! To remove an existing value, use something like %systemroot%\system32\inetsrv\appcmd.exe set config "Default Web Site/MyVirtualDir" -section:system.webServer/aspNetCore /-"environmentVariables.[name='ASPNETCORE_MyKey',value='value-to-be-removed']" /commit:site.

if it was an IPv6 address, have a look at this: https://code.google.com/p/android/issues/detail?id=33046

Looks like there was a bug in Android that was fixed in 4.3(?).

Dockerfile is good if you only have one docker file (per-directory). You can use whatever standard you want if you need multiple docker files in the same directory - if you have a good reason. In a recent project there were AWS docker files and local dev environment files because the environments differed enough:

Dockerfile Dockerfile.aws

Add extra columns as null for the table having less columns like

Select Col1, Col2, Col3, Col4, Col5 from Table1
Union
Select Col1, Col2, Col3, Null as Col4, Null as Col5 from Table2

This does what you want:

public static void main (String[] args) {
    String a = "\\joe\\jill\\";
    String b = a.replaceAll("\\\\$", "").replaceAll("^\\\\", "");
    System.out.println(b);
}

The $ is used to remove the sequence in the end of string. The ^ is used to remove in the beggining.

As an alternative, you can use the syntax:

String b = a.replaceAll("\\\\$|^\\\\", "");

The | means "or".

In case you want to trim other chars, just adapt the regex:

String b = a.replaceAll("y$|^x", ""); // will remove all the y from the end and x from the beggining

Very safe:

the annual risk of a given person being hit by a meteorite is estimated to be one chance in 17 billion, which means the probability is about 0.00000000006 (6 × 10^-11), equivalent to the odds of creating a few tens of trillions of UUIDs in a year and having one duplicate. In other words, only after generating 1 billion UUIDs every second for the next 100 years, the probability of creating just one duplicate would be about 50%.

Caveat:

However, these probabilities only hold when the UUIDs are generated using sufficient entropy. Otherwise, the probability of duplicates could be significantly higher, since the statistical dispersion might be lower. Where unique identifiers are required for distributed applications, so that UUIDs do not clash even when data from many devices is merged, the randomness of the seeds and generators used on every device must be reliable for the life of the application. Where this is not feasible, RFC4122 recommends using a namespace variant instead.

Also see the current section on the same subject on the same Universally unique identifier article, Collisions.

I am not clearly about it but typically one server has one database (with many users), if you create many databases mean that you create many instances, listeners, ... as well. So you can check your LISTENER to identify it.

In my testing I created 2 databases (dbtest and dbtest_1) so when I check my LISTENER status it appeared like this:

lsnrctl status

....

STATUS of the LISTENER

.....

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=10.10.20.20)(PORT=1521)))

Services Summary...

Service "dbtest" has 1 instance(s).

Instance "dbtest", status READY, has 1 handler(s) for this service...

Service "dbtest1XDB" has 1 instance(s).

Instance "dbtest1", status READY, has 1 handler(s) for this service...

Service "dbtest_1" has 1 instance(s).

Instance "dbtest1", status READY, has 1 handler(s) for this service... The command completed successfully

One common idiom is:

char* c = source;
while (*c) putchar(*c++);

A few notes:

• In C, strings are null-terminated. You iterate while the read character is not the null character.
• *c++ increments c and returns the dereferenced old value of c.
• printf("%s") prints a null-terminated string, not a char. This is the cause of your access violation.

You might find it useful to lookup the classes on oracle. Eg:

http://download.oracle.com/javase/1.4.2/docs/api/javax/swing/JFrame.html

There you can see that JFrame extends JComponent and JContainer.

JComponent is a a basic object that can be drawn, JContainer extends this so that you can add components to it. JPanel and JFrame both extend JComponent as you can add things to them. JFrame provides a window, whereas JPanel is just a panel that goes inside a window. If that makes sense.

You might include the implementation of itoa in your project.
Here's itoa modified to work with std::string: http://www.strudel.org.uk/itoa/

995 is an error reported by the IO Completion Port. The error comes since you try to continue read from the socket when it has most likely been closed.

Receiving 0 bytes from EndRecieve means that the socket has been closed, as does most exceptions that EndRecieve will throw.

You need to start dealing with those situations.

Never ever ignore exceptions, they are thrown for a reason.

Update

There is nothing that says that the server does anything wrong. A connection can be lost for a lot of reasons such as idle connection being closed by a switch/router/firewall, shaky network, bad cables etc.

What I'm saying is that you MUST handle disconnections. The proper way of doing so is to dispose the socket and try to connect a new one at certain intervals.

As for the receive callback a more proper way of handling it is something like this (semi pseudo code):

public void OnDataReceived(IAsyncResult asyn)
{
    BLCommonFunctions.WriteLogger(0, "In :- OnDataReceived", ref swReceivedLogWriter, strLogPath, 0);

    try
    {
        SocketPacket client = (SocketPacket)asyn.AsyncState;

        int bytesReceived = client.thisSocket.EndReceive(asyn); //Here error is coming
        if (bytesReceived == 0)
        {
          HandleDisconnect(client);
          return;
        }
    }
    catch (Exception err)
    {
       HandleDisconnect(client);
    }

    try
    {
        string strHEX = BLCommonFunctions.ByteArrToHex(theSockId.dataBuffer);                    

        //do your handling here
    }
    catch (Exception err)
    {
        // Your logic threw an exception. handle it accordinhly
    }

    try
    {
       client.thisSocket.BeginRecieve(.. all parameters ..);
    }
    catch (Exception err)
    {
       HandleDisconnect(client);
    }
}

the reason to why I'm using three catch blocks is simply because the logic for the middle one is different from the other two. Exceptions from BeginReceive/EndReceive usually indicates socket disconnection while exceptions from your logic should not stop the socket receiving.

Referring to answer of @Chris,

We can also go to parent directory of batch file and run commands using following

cd /d %~dp0..
<OTHER_BATCH_COMMANDS>
cmd.exe

To understand working of command cd /d %~dp0.. please refer below link

What does it mean by command cd /d %~dp0 in Windows

re (as in regular expressions) allows splitting on multiple characters at once:

$ string = "blah, lots  ,  of ,  spaces, here "
$ re.split(', ',string)
['blah', 'lots  ', ' of ', ' spaces', 'here ']

This doesn't work well for your example string, but works nicely for a comma-space separated list. For your example string, you can combine the re.split power to split on regex patterns to get a "split-on-this-or-that" effect.

$ re.split('[, ]',string)
['blah',
 '',
 'lots',
 '',
 '',
 '',
 '',
 'of',
 '',
 '',
 '',
 'spaces',
 '',
 'here',
 '']

Unfortunately, that's ugly, but a filter will do the trick:

$ filter(None, re.split('[, ]',string))
['blah', 'lots', 'of', 'spaces', 'here']

Voila!

As you've guessed, the right syntax is

del df['column_name']

It's difficult to make del df.column_name work simply as the result of syntactic limitations in Python. del df[name] gets translated to df.__delitem__(name) under the covers by Python.

C# Code:

Note:

We need to tell the compiler to not prefer a particular build platform.

Go to Visual Studio > Project Properties > Build > Uncheck "Prefer 32 bit"

Reason:

By default for most .NET Projects is "Any CPU 32-bit preferred"

When you uncheck 32 bit assembly will:

I was facing the same problem, following code worked for me:

print_r($params);

To see if a dataframe is empty, I argue that one should test for the length of a dataframe's columns index:

if len(df.columns) == 0: 1

Reason:

According to the Pandas Reference API, there is a distinction between:

• an empty dataframe with 0 rows and 0 columns
• an empty dataframe with rows containing NaN hence at least 1 column

Arguably, they are not the same. The other answers are imprecise in that df.empty, len(df), or len(df.index) make no distinction and return index is 0 and empty is True in both cases.

Examples

Example 1: An empty dataframe with 0 rows and 0 columns

In [1]: import pandas as pd
        df1 = pd.DataFrame()
        df1
Out[1]: Empty DataFrame
        Columns: []
        Index: []

In [2]: len(df1.index)  # or len(df1)
Out[2]: 0

In [3]: df1.empty
Out[3]: True

Example 2: A dataframe which is emptied to 0 rows but still retains n columns

In [4]: df2 = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
        df2
Out[4]:    AA  BB
        0   1  11
        1   2  22
        2   3  33

In [5]: df2 = df2[df2['AA'] == 5]
        df2
Out[5]: Empty DataFrame
        Columns: [AA, BB]
        Index: []

In [6]: len(df2.index)  # or len(df2)
Out[6]: 0

In [7]: df2.empty
Out[7]: True

Now, building on the previous examples, in which the index is 0 and empty is True. When reading the length of the columns index for the first loaded dataframe df1, it returns 0 columns to prove that it is indeed empty.

In [8]: len(df1.columns)
Out[8]: 0

In [9]: len(df2.columns)
Out[9]: 2

Critically, while the second dataframe df2 contains no data, it is not completely empty because it returns the amount of empty columns that persist.

Why it matters

Let's add a new column to these dataframes to understand the implications:

# As expected, the empty column displays 1 series
In [10]: df1['CC'] = [111, 222, 333]
         df1
Out[10]:    CC
         0 111
         1 222
         2 333
In [11]: len(df1.columns)
Out[11]: 1

# Note the persisting series with rows containing `NaN` values in df2
In [12]: df2['CC'] = [111, 222, 333]
         df2
Out[12]:    AA  BB   CC
         0 NaN NaN  111
         1 NaN NaN  222
         2 NaN NaN  333
In [13]: len(df2.columns)
Out[13]: 3

It is evident that the original columns in df2 have re-surfaced. Therefore, it is prudent to instead read the length of the columns index with len(pandas.core.frame.DataFrame.columns) to see if a dataframe is empty.

Practical solution

# New dataframe df
In [1]: df = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
        df
Out[1]:    AA  BB
        0   1  11
        1   2  22
        2   3  33

# This data manipulation approach results in an empty df
# because of a subset of values that are not available (`NaN`)
In [2]: df = df[df['AA'] == 5]
        df
Out[2]: Empty DataFrame
        Columns: [AA, BB]
        Index: []

# NOTE: the df is empty, BUT the columns are persistent
In [3]: len(df.columns)
Out[3]: 2

# And accordingly, the other answers on this page
In [4]: len(df.index)  # or len(df)
Out[4]: 0

In [5]: df.empty
Out[5]: True

# SOLUTION: conditionally check for empty columns
In [6]: if len(df.columns) != 0:  # <--- here
            # Do something, e.g. 
            # drop any columns containing rows with `NaN`
            # to make the df really empty
            df = df.dropna(how='all', axis=1)
        df
Out[6]: Empty DataFrame
        Columns: []
        Index: []

# Testing shows it is indeed empty now
In [7]: len(df.columns)
Out[7]: 0

Adding a new data series works as expected without the re-surfacing of empty columns (factually, without any series that were containing rows with only NaN):

In [8]: df['CC'] = [111, 222, 333]
         df
Out[8]:    CC
         0 111
         1 222
         2 333

Get rid of the escape characters before storing or manipulating the raw string:

You could change any backslashes of the path '\' to forward slashes '/' before storing them in a variable. The forward slashes don't need to be escaped:

>>> mypath = os.getcwd().replace('\\','/')  
>>> os.path.exists(mypath)  
True  
>>>   

HTC One m7 running fresh Cyanogenmod 11.

Phone is connected USB and tethering my data connection.

Then I get this surprise:

cinder@ultrabook:~/temp/htc_m7/2015-11-11$ adb shell
error: insufficient permissions for device

cinder@ultrabook:~/temp/htc_m7/2015-11-11$ adb devices
List of devices attached
????????????    no permissions

SOLUTION: Turn tethering OFF on phone.

cinder@ultrabook:~/temp/htc_m7/2015-11-11$ adb devices
List of devices attached
HT36AW908858    device

another workaround:

var myarray = [];
$("#test").click(function() {
    myarray[index]=$("#drop").val();
    alert(myarray);
});

i wanted to add all checked checkbox to array. so example, if .each is used:

var vpp = [];
var incr=0;
$('.prsn').each(function(idx) {
   if (this.checked) {
       var p=$('.pp').eq(idx).val();
       vpp[incr]=(p);
       incr++;
   }
});
//do what ever with vpp array;

Just remove activation section, I don't know why -Pdev1 doesn't override default false activation. But if you omit this:

<activation> <activeByDefault>false</activeByDefault> </activation>

then your profile will be activated only after explicit declaration as -Pdev1

If you don't want to install Non-Microsoft tools, please download STRINGS.EXE from Microsoft Sysinternals and make a procedure like this one:

@echo off
if '%1' == '' goto NOPARAM
if '%2' == '' goto NOPARAM
if not exist %1 goto NOFOLDER

echo ------------------------------------------
echo - %1 : folder
echo - %2 : string to be searched in the folder
echo - PLEASE WAIT FOR THE RESULTS ...
strings -s %1\* | findstr /i %2 > grep.txt
notepad.exe grep.txt

goto END

:NOPARAM rem - input command not correct
echo ====================================
echo Usage of GREP.CMD:
echo   Grep "SearchFolder" SearchString
echo Please specify all parameters
echo ====================================
goto END

:NOFOLDER
echo Folder %1 does not exist
goto END

:END rem - exit
