It should be noted that it is an anti-pattern to copy properties that never change to the state (just access .props directly in that case). If you have a state variable that will change eventually but starts with a value from .props, you don't even need a constructor call - these local variables are initialized after a call to the parent's constructor:

class FirstComponent extends React.Component {
  state = {
    x: this.props.initialX,
    // You can even call functions and class methods:
    y: this.someMethod(this.props.initialY),
  };
}

This is a shorthand equivalent to the answer from @joews below. It seems to only work on more recent versions of es6 transpilers, I have had issues with it on some webpack setups. If this doesn't work for you, you can try adding the babel plugin babel-plugin-transform-class-properties, or you can use the non-shorthand version by @joews below.

In addition to previous post you can have

<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

Jsf 2.0

html

<input type="hidden" #fondovalor value="valores">
     <button (click)="getFotoFondo()">Obtener</button>

ts

@ViewChild('fondovalor') fondovalor:ElementRef;

getFotoFondo(){ 
        const valueInput = this.fondovalor.nativeElement.value
}

I tried use [disabled]="!editmode" but it not work in my case.

This is my solution [disabled]="!editmode ? 'disabled': null" , I share for whom concern.

<button [disabled]="!editmode ? 'disabled': null" 
    (click)='loadChart()'>
            <div class="btn-primary">Load Chart</div>
    </button>

You can try adding a question mark as below. This worked for me.

 componentWillReceiveProps(nextProps) {
    this.setState({
        title: nextProps?.blog?.title,
        body: nextProps?.blog?.content
     })
    }

This can be achieved via a hack, Navigate to some sample component and then navigate to the component that you want to reload.

this.router.navigateByUrl('/SampleComponent', { skipLocationChange: true });
this.router.navigate(["yourLandingComponent"]);

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

I found the answer to the second part of my questions. Yes, a class can implement an interface that is in a different class as long that the interface is declared as public.

Hello you can make use of input and output. Input let you to pass variable form parent to child. Output the same but from child to parent.

The easiest way is to pass "startdate" and "endDate" as input

<calendar [startDateInCalendar]="startDateInSearch" [endDateInCalendar]="endDateInSearch" ></calendar>

In this way you have your startdate and enddate directly in search page. Let me know if it works, or think another way. Thanks

What you need is to map your array of objects and remember that every item will be an object, so that you will use for instance dot notation to take the values of the object.

In your component

 [
    {
        name: 'Sam',
        email: '[email protected]'
    },

    {
        name: 'Ash',
        email: '[email protected]'
    }
].map((anObjectMapped, index) => {
    return (
        <p key={`${anObjectMapped.name}_{anObjectMapped.email}`}>
            {anObjectMapped.name} - {anObjectMapped.email}
        </p>
    );
})

And remember when you put an array of jsx it has a different meaning and you can not just put object in your render method as you can put an array.

Take a look at my answer at mapping an array to jsx

Well, it's too late to post an answer, but I feel my explanation will be easy to understand for beginners with Angular. The following is one of the examples that I give during my presentation.

Consider your angular Application as a building. A building can have N number of apartments in it. An apartment is considered as a module. An Apartment can then have N number of rooms which correspond to the building blocks of an Angular application named components.

Now each apartment (Module)` will have rooms (Components), lifts (Services) to enable larger movement in and out the apartments, wires (Pipes) to transform around and make it useful in the apartments.

You will also have places like swimming pool, tennis court which are being shared by all building residents. So these can be considered as components inside SharedModule.

Basically, the difference is as follows,

Follow my slides to understand the building blocks of an Angular application

Here is my session on Building Blocks of Angular for beginners

In our case we FIXED by adding changeDetection into the component and call detectChanges() in ngAfterContentChecked, code as follows

@Component({
  selector: 'app-spinner',
  templateUrl: './spinner.component.html',
  styleUrls: ['./spinner.component.scss'],
  changeDetection: ChangeDetectionStrategy.OnPush
})
export class SpinnerComponent implements OnInit, OnDestroy, AfterContentChecked {

  show = false;

  private subscription: Subscription;

  constructor(private spinnerService: SpinnerService, private changeDedectionRef: ChangeDetectorRef) { }

  ngOnInit() {
    this.subscription = this.spinnerService.spinnerState
      .subscribe((state: SpinnerState) => {
        this.show = state.show;
      });
  }

  ngAfterContentChecked(): void {
      this.changeDedectionRef.detectChanges();
  }

  ngOnDestroy() {
    this.subscription.unsubscribe();
  }

}

There is a "3 of 9" control on CodeProject: Barcode .NET Control

You can use the following methods to update the value of a reactive form control. Any of the following method will suit for your need.

Methods using setValue()

this.form.get("dept").setValue(selected.id);
this.form.controls["dept"].setValue(selected.id);

Methods using patchValue()

this.form.get("dept").patchValue(selected.id);
this.form.controls['dept'].patchValue(selected.id);
this.form.patchValue({"dept": selected.id});

Last method will loop thorough all the controls in the form so it is not preferred when updating single control

You can use any of the method inside the event handler

deptSelected(selected: { id: string; text: string }) {
     // any of the above method can be added here
}

You can update multiple controls in the form group if required using the

this.form.patchValue({"dept": selected.id, "description":"description value"});

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

If you want to allow all the fonts from a folder for a specific domain then you can use this:

  <location path="assets/font">
    <system.webServer>
      <httpProtocol>
        <customHeaders>
          <add name="Access-Control-Allow-Origin" value="http://localhost:3000" />
        </customHeaders>
      </httpProtocol>
    </system.webServer>
  </location>

where assets/font is the location where all fonts are and http://localhost:3000 is the location which you want to allow.

new File(absolutePath).getName();

I have use @Mirko N. answser using made the new Custom EditText

 public class EditViewCustom extends EditText {

    Button cancelBtn;
    RelativeLayout titleReleLayout;
    public EditViewCustom(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public EditViewCustom(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public EditViewCustom(Context context) {
        super(context);
    }

    public void setViews(Button cancelBtn,RelativeLayout titleReleLayout){
        this.cancelBtn = cancelBtn;
        this.titleReleLayout = titleReleLayout;
    }

    @Override
    public boolean onKeyPreIme(int keyCode, KeyEvent event) {
        if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
            Log.d("KEYCODE_BACK","KEYCODE_BACK");
            cancelBtn.setVisibility(View.GONE);
            this.setFocusableInTouchMode(false);
            this.setFocusable(false);
            titleReleLayout.setVisibility(View.VISIBLE);

            return super.onKeyPreIme(keyCode, event);
          }

        return super.onKeyPreIme(keyCode, event);
    }

}

Then set data from your activity

 searchEditView.setViews(cancelBtn, titleRelativeLayout);

Thank you.

a1 = c(1, 2, 3, 4, 5)
a2 = c(6, 7, 8, 9, 10)

aframe = data.frame(a1, a2, a3)
avector <- as.vector(aframe['a2'])

avector<-unlist(avector)
#this will return a vector of type "integer"

Goyuix's solution works great, but as presented it gives me this error: "The requested FTP command is not supported when using HTTP proxy."

Adding this line after $ftp.UsePassive = $true fixed the problem for me:

$ftp.Proxy = $null;

Here is the most efficient way I have come across to solve this problem, use the willDisplayCell delegate method (this takes care of the white color for the text label background as well when using cell.textLabel.text and/or cell.detailTextLabel.text):

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { ... }

When this delegate method is called the color of the cell is controlled via the cell rather than the table view, as when you use:

- (UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath { ... }

So within the body of the cell delegate method add the following code to alternate colors of cells or just use the function call to make all the cells of the table the same color.

if (indexPath.row % 2)
{
    [cell setBackgroundColor:[UIColor colorWithRed:.8 green:.8 blue:1 alpha:1]];
}
else [cell setBackgroundColor:[UIColor clearColor]];

This solution worked well in my circumstance...

For React Native version = 0.60, in your root file create a file called react-native.config.js and put the followings, then just run react-native link

module.exports = {
  assets: ["./assets/fonts"]
}

My favorite method to use would be the BorderLayout method. Here are the five examples with each position the component could go in. The example is for if the component were a button. We will add it to a JPanel, p. The button will be called b.

//To align it to the left
p.add(b, BorderLayout.WEST);

//To align it to the right
p.add(b, BorderLayout.EAST);

//To align it at the top
p.add(b, BorderLayout.NORTH);

//To align it to the bottom
p.add(b, BorderLayout.SOUTH);

//To align it to the center
p.add(b, BorderLayout.CENTER);

Don't forget to import it as well by typing:

import java.awt.BorderLayout;

There are also other methods in the BorderLayout class involving things like orientation, but you can do your own research on that if you curious about that. I hope this helped!

If you have problems with numbers (say 1, 2, 10, 12 which will be sorted 1, 10, 12, 2) you can use LINQ:

var arr = arr.OrderBy(x=>x).ToArray();

For users of SQL 2000, the actual command that will provide this information is:

select c.text
from sysobjects     o
join syscomments    c on c.id = o.id
where o.name = '<view_name_here>'
  and o.type      = 'V'

You cannot. A basic numeric constant is considered an integer (or long if followed by a "L"), so you must explicitly downcast it to a byte to pass it as a parameter. As far as I know there is no shortcut.

Okay so there might be various reasons behind Sql Server Management Studio's(SSMS) above behaviour:

1.It seems that if our SSMS hasn't been opened for quite some while, the OS puts it to sleep.The solution is to manually activate our SQL server as shown below:

• Go to Computer Management-->Services and Applications-->Services. As you see that the status of this service is currently blank which means that it has stopped.
• Double click the SQL Server option and a wizard box will popup as shown below.Set the startup type to "Automatic" and click on the start button which will start our SQL service.
• Now check the status of your SQL Server. It will display as "Running".
• Also you need to check that other associated services which are also required by our SQL Server to fully function are also up and running such as SQL Server Browser,SQL Server Agent,etc.

2.The second reason could be due to incorrect credentials entered.So enter in the correct credentials.

3.If you happen to forget your credentials then follow the below steps:

• First what you could do is sign in using "Windows Authentication" instead of "SQL Server Authentication".This will work only if you are logged in as administrator.
• Second case what if you forget your local server name? No issues simply use "." instead of your server name and it should work.

NOTE: This will only work for local server and not for remote server.To connect to a remote server you need to have an I.P. address of your remote server.

From your post, I understand that you cannot set the width to your li.

How about this?

ul {
  border:2px solid red;
  display:inline-block;
}

li {
  display:inline;
  padding:0 30%; /* try adjusting the side % to give a feel of center aligned.*/
}

<ul>
    <li>Hello</li>
    <li>Hezkdhkfskdhfkllo</li>
    <li>Hello</li>
</ul>

Here's a demo. http://codepen.io/anon/pen/HhBwx

Some hints on detaching the child process from the calling one (starting the child process in background).

Suppose you want to start a long task from a CGI script. That is, the child process should live longer than the CGI script execution process.

The classical example from the subprocess module documentation is:

import subprocess
import sys

# Some code here

pid = subprocess.Popen([sys.executable, "longtask.py"]) # Call subprocess

# Some more code here

The idea here is that you do not want to wait in the line 'call subprocess' until the longtask.py is finished. But it is not clear what happens after the line 'some more code here' from the example.

My target platform was FreeBSD, but the development was on Windows, so I faced the problem on Windows first.

On Windows (Windows XP), the parent process will not finish until the longtask.py has finished its work. It is not what you want in a CGI script. The problem is not specific to Python; in the PHP community the problems are the same.

The solution is to pass DETACHED_PROCESS Process Creation Flag to the underlying CreateProcess function in Windows API. If you happen to have installed pywin32, you can import the flag from the win32process module, otherwise you should define it yourself:

DETACHED_PROCESS = 0x00000008

pid = subprocess.Popen([sys.executable, "longtask.py"],
                       creationflags=DETACHED_PROCESS).pid

/* UPD 2015.10.27 @eryksun in a comment below notes, that the semantically correct flag is CREATE_NEW_CONSOLE (0x00000010) */

On FreeBSD we have another problem: when the parent process is finished, it finishes the child processes as well. And that is not what you want in a CGI script either. Some experiments showed that the problem seemed to be in sharing sys.stdout. And the working solution was the following:

pid = subprocess.Popen([sys.executable, "longtask.py"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)

I have not checked the code on other platforms and do not know the reasons of the behaviour on FreeBSD. If anyone knows, please share your ideas. Googling on starting background processes in Python does not shed any light yet.

EDIT: After further investigation, my original assumption that this was an anomaly (bug?) of the declare @var datatype = value syntax is incorrect.

I modified your script for 2005 since that syntax is not supported, then tried the modified version on 2008. In 2005, I get the Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. error message. In 2008, the modified script is still successful.

declare @KMsg varchar(max); set @KMsg = REPLICATE('a',1024);
declare @MMsg varchar(max); set @MMsg = REPLICATE(@KMsg,1024);
declare @GMsg varchar(max); set @GMsg = REPLICATE(@MMsg,1024);
declare @GGMMsg varchar(max); set @GGMMsg = @GMsg + @GMsg + @MMsg;
select LEN(@GGMMsg)

You can use two for loops in same line by using zip function

Code:

list1 = ['Abbas', 'Ali', 'Usman']
list2 = ['Kamran', 'Asgar', 'Hamza', 'Umer']
list3 = []
for i,j in zip(list1,list2):
    list3.append(i)
    list3.append(j)
print(list3)

Output:

['Abbas', 'Kamran', 'Ali', 'Asgar', 'Usman', 'Hamza']

So, by using zip function, we can use two for loops or we can iterate two lists in same row.

Let me add a source I just discovered, found here.

It has lots of historical stock data in csv format and was gathered by Andy Pavlo, who according to his homepage is an "Assistant Professor in the Computer Science Department at Carnegie Mellon University".

You need to read up on event bubbling and for sure remove inline event handling if you have jQuery anyway

Test the click on the div and examine the target

Live Demo

$(".expandable-panel-heading").on("click",function (e) {
    if (e.target.id =="ancherComplaint") { // or test the tag
        e.preventDefault(); // or e.stopPropagation()
        markActiveLink(e.target);
    }    
    else alert('123');
});
function markActiveLink(el) {   
    alert(el.id);
} 

In your screenshot, you didn't specify any module: try setting "libsystem_c.dylib"

I did that, and it works : breakpoint stops here (although the stacktrace often rise from some obscure system lib...)

Another difference between bool and BOOL is that they do not convert exactly to the same kind of objects, when you do key-value observing, or when you use methods like -[NSObject valueForKey:].

As everybody has said here, BOOL is char. As such, it is converted to an NSNumber holding a char. This object is indistinguishable from an NSNumber created from a regular char like 'A' or '\0'. You have totally lost the information that you originally had a BOOL.

However, bool is converted to an CFBoolean, which behaves the same as NSNumber, but which retains the boolean origin of the object.

I do not think that this is an argument in a BOOL vs. bool debate, but this may bite you one day.

Generally speaking, you should go with BOOL, since this is the type used everywhere in the Cocoa/iOS APIs (designed before C99 and its native bool type).

A moving average can also be calculated and visualized directly in a line chart by using the following code:

Example using stock price data:

import pandas_datareader.data as web
import matplotlib.pyplot as plt
import datetime
plt.style.use('ggplot')

# Input variables
start = datetime.datetime(2016, 1, 01)
end = datetime.datetime(2018, 3, 29)
stock = 'WFC'

# Extrating data
df = web.DataReader(stock,'morningstar', start, end)
df = df['Close']

print df 

plt.plot(df['WFC'],label= 'Close')
plt.plot(df['WFC'].rolling(9).mean(),label= 'MA 9 days')
plt.plot(df['WFC'].rolling(21).mean(),label= 'MA 21 days')
plt.legend(loc='best')
plt.title('Wells Fargo\nClose and Moving Averages')
plt.show()

Just a side note for anyone that stumbles onto this same inquiry... My Operating System is 64 bit - so of course I downloaded the 64 bit MySQL driver... however, my Office applications are 32 bit... Once I downloaded the 32 bit version, the error went away and I could move forward.

fig, (ax1, ax2, ax3, ax4) = plt.subplots(nrows=1, ncols=4,figsize=(11, 7))

grid = plt.GridSpec(2, 2, wspace=0.2, hspace=0.5)

ax1 = plt.subplot(grid[0, 0])
ax2 = plt.subplot(grid[0, 1:])
ax3 = plt.subplot(grid[1, :1])
ax4 = plt.subplot(grid[1, 1:])

ax1.title.set_text('First Plot')
ax2.title.set_text('Second Plot')
ax3.title.set_text('Third Plot')
ax4.title.set_text('Fourth Plot')

plt.show()

The best practice is to explicitly list the columns:

Insert Into TableName(col1, col2,col2) Values(?, ?, ?)

Otherwise, your original insert will break if you add another column to your table.

Could me multiple reason for this. But you want might forget to add as @Bean for component which you have did @Autowired.

In my case, i have forgot to decorate with @Bean which causing this issue.

@tamir; you cna do it with css3 property.

img{
-webkit-box-shadow: 0px 0px 3px 5px #f2e1f2;
-moz-box-shadow: 0px 0px 3px 5px #f2e1f2;
box-shadow: 0px 0px 3px 5px #f2e1f2; 
}

check the fiddle http://jsfiddle.net/XUC5q/1/ & your can generate from here http://css3generator.com/

If you need it to work in older versions of IE, you can use CSS3 PIE to emulate the box-shadow in those browsers & you can use filter as kyle said like this

filter:progid:DXImageTransform.Microsoft.Glow(color='red', Strength='5')

you can generate your filter from here http://samples.msdn.microsoft.com/workshop/samples/author/filter/Glow.htm

I had a similar problem, which turned out to be caused by missing double quotes off the table and schema name.

Another option I have googled, but contains several replace ...

SELECT REPLACE(REPLACE(REPLACE(CONVERT(VARCHAR(19), CONVERT(DATETIME, getdate(), 112), 126), '-', ''), 'T', ''), ':', '') 

If that's a valid date/time entry then excel simply stores it as a number (days are integers and the time is the decimal part) so you can do a simple subtraction.

I'm not sure if 7/6 is 7th June or 6th July, assuming the latter then it's a future date so you can get the difference in days with

=INT(A1-TODAY())

Make sure you format result cell as general or number (not date)

I like to use Action in place of MethodInvoker, it is shorter and looks cleaner.

Invoke((Action)(() => {
    DoSomething();
}));

// OR

Invoke((Action)delegate {
    DoSomething();
});

Eg.

// Thread-safe update on a form control
public void DisplayResult(string text){
    if (txtResult.InvokeRequired){
        txtResult.Invoke((Action)delegate {
            DisplayResult(text);
        });
        return;
    }

    txtResult.Text += text + "\r\n";
}

Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):

Sub Module for Connecting to MS SQL with Remote Host & Username/Password

Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String

'Setup the connection string for accessing MS SQL database
   'Make sure to change:
       '1: PASSWORD
       '2: USERNAME
       '3: REMOTE_IP_ADDRESS
       '4: DATABASE
    ConnectionString = "Provider=SQLOLEDB.1;Password=PASSWORD;Persist Security Info=True;User ID=USERNAME;Data Source=REMOTE_IP_ADDRESS;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=DATABASE"

    'Opens connection to the database
    cnn.Open ConnectionString
    'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
    cnn.CommandTimeout = 900

    'This is your actual MS SQL query that you need to run; you should check this query first using a more robust SQL editor (such as HeidiSQL) to ensure your query is valid
    StrQuery = "SELECT TOP 10 * FROM tbl_table"

    'Performs the actual query
    rst.Open StrQuery, cnn
    'Dumps all the results from the StrQuery into cell A2 of the first sheet in the active workbook
    Sheets(1).Range("A2").CopyFromRecordset rst
End Sub

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

http://www.coderanch.com/t/515475/JDBC/databases/sql-insert-statement-giving-sqlcode

You need to use the autoGenerate property

Your primary key annotation should be like this:

@PrimaryKey(autoGenerate = true)

Reference for PrimaryKey.

> 2020 Answer = The Easy Way using Google Apps Script (5 Mins)

We had a similar challenge to solve yesterday, and we solved it using a Google Apps Script!

Send Email From an HTML Form Without a Backend (Server) via Google!

The solution takes 5 mins to implement and I've documented with step-by-step instructions: https://github.com/nelsonic/html-form-send-email-via-google-script-without-server

Brief Overview

A. Using the sample script, deploy a Google App Script

Deploy the sample script as a Google Spreadsheet APP Script: google-script-just-email.js

remember to set the TO_ADDRESS in the script to where ever you want the emails to be sent.
and copy the APP URL so you can use it in the next step when you publish the script.

B. Create your HTML Form and Set the action to the App URL

Using the sample html file: index.html create a basic form.

remember to paste your APP URL into the form action in the HTML form.

C. Test the HTML Form in your Browser

Open the HTML Form in your Browser, Input some data & submit it!

Submit the form. You should see a confirmation that it was sent:

Open the inbox for the email address you set (above)

Done.

Everything about this is customisable, you can easily style/theme the form with your favourite CSS Library and Store the submitted data in a Google Spreadsheet for quick analysis.
The complete instructions are available on GitHub:

Since 0.14.1, you can now do nlargest and nsmallest on a groupby object:

In [23]: df.groupby('id')['value'].nlargest(2)
Out[23]: 
id   
1   2    3
    1    2
2   6    4
    5    3
3   7    1
4   8    1
dtype: int64

There's a slight weirdness that you get the original index in there as well, but this might be really useful depending on what your original index was.

If you're not interested in it, you can do .reset_index(level=1, drop=True) to get rid of it altogether.

(Note: From 0.17.1 you'll be able to do this on a DataFrameGroupBy too but for now it only works with Series and SeriesGroupBy.)

Try this:

SELECT CONVERT(date, GETDATE())

If you have access to the C++ 11 libraries, check out the std::chrono library. You can use it to get the milliseconds since the Unix Epoch like this:

#include <chrono>

// ...

using namespace std::chrono;
milliseconds ms = duration_cast< milliseconds >(
    system_clock::now().time_since_epoch()
);

git push --set-upstream origin <branch_name>_test

--set-upstream sets the association between your local branch and the remote. You only have to do it the first time. On subsequent pushes you can just do:

git push

If you don't have origin set yet, use:

git remote add origin <repository_url> then retry the above command.

You can:

input[type="text"][disabled] {
   color: red;
}

First thing first, button() is a jQuery ui function to create a button widget which has nothing to do with jQuery core, it just styles the button.
So if you want to use the widget add jQuery ui's javascript and CSS files or alternatively remove it, like this:

$("#filter").click(function(){
    alert('clicked!');
});

Another thing that might have caused you the problem is if you didn't wait for the input to be rendered and wrote the code before the input. jQuery has the ready function, or it's alias $(func) which execute the callback once the DOM is ready.
Usage:

$(function(){
    $("#filter").click(function(){
        alert('clicked!');
    });
});

So even if the order is this it will work:

$(function(){
    $("#filter").click(function(){
        alert('clicked!');
    });
});

<input type="button" id="filter" name="filter" value="Filter" />

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

I also wanted similar functionality where I have a File Input Control with display:none and a Button control where I wanted to trigger click event of File Input Control when I click on the button, below is the code to do so

<input type="button" (click)="fileInput.click()" class="btn btn-primary" value="Add From File">
<input type="file" style="display:none;" #fileInput/>

as simple as that and it's working flawlessly...

Always remember, when comparing strings, you should use === operator (strict comparison) and not == operator (loose comparison).

You are trying to return an object. Because there is no good way to represent an object as a string, the object's .toString() value is automatically set as "[object Object]".

For that single rule you have, there isn't any shorter way to do it. The child combinator is the same in CSS and in Sass/SCSS and there's no alternative to it.

However, if you had multiple rules like this:

#foo > ul > li > ul > li > a:nth-child(3n+1) {
    color: red;
}

#foo > ul > li > ul > li > a:nth-child(3n+2) {
    color: green;
}

#foo > ul > li > ul > li > a:nth-child(3n+3) {
    color: blue;
}

You could condense them to one of the following:

/* Sass */
#foo > ul > li > ul > li
    > a:nth-child(3n+1)
        color: red
    > a:nth-child(3n+2)
        color: green
    > a:nth-child(3n+3)
        color: blue

/* SCSS */
#foo > ul > li > ul > li {
    > a:nth-child(3n+1) { color: red; }
    > a:nth-child(3n+2) { color: green; }
    > a:nth-child(3n+3) { color: blue; }
}

Phuong:

Sorting 40,000 random numbers:

0.022 seconds

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Random;


public class test
{
    public static void main(String[] args)
    {
        List<Integer> nums = new ArrayList<Integer>();
        Random rand = new Random();
        for( int i = 0; i < 40000; i++ )
        {
            nums.add( rand.nextInt(Integer.MAX_VALUE) );
        }

        long start = System.nanoTime();
        Collections.sort(nums);
        long end = System.nanoTime();

        System.out.println((end-start)/1e9);
    }
}   

Since you rarely need sorting, as per your problem statement, this is probably more efficient than it needs to be.

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

Since the API you're calling is async, the Parallel.ForEach version doesn't make much sense. You shouldnt use .Wait in the WaitAll version since that would lose the parallelism Another alternative if the caller is async is using Task.WhenAll after doing Select and ToArray to generate the array of tasks. A second alternative is using Rx 2.0

Simply use this:

$user = User::whereEmail($email)->first();

Use Collections.emptyList() if you want to make sure that the returned list is never modified.

This is what is returned on calling emptyList():

/**
 * The empty list (immutable). 
 */
public static final List EMPTY_LIST = new EmptyList();

Maybe I'm missing something here, but usually calling .SingleOrDefault() is the way to go to return either the single element in the list, or a default value (null for reference or nullable types) if the list is empty. It generates an exception if the list contains more than one element.

Use FirstOrDefault() to cover the case where you could have more than one.

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

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

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

This is also a viable alternative :

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

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

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

user-scalable=0

This no longer works on iOS 10. Apple removed the feature.

There is no way yo can disable zoom website on iOS now, unless you make gross platform app.

Check if all the parameters of functions are defined before they are called. I faced this problem while practicing Kaggle.

Fastest on my tests:

conn.row_factory = lambda c, r: dict(zip([col[0] for col in c.description], r))
c = conn.cursor()

%timeit c.execute('SELECT * FROM table').fetchall()
19.8 µs ± 1.05 µs per loop (mean ± std. dev. of 7 runs, 100000 loops each)

vs:

conn.row_factory = lambda c, r: dict([(col[0], r[idx]) for idx, col in enumerate(c.description)])
c = conn.cursor()

%timeit c.execute('SELECT * FROM table').fetchall()
19.4 µs ± 75.6 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

You decide :)

I wrote an add-on to overcome this issue in Firefox (Chrome, Opera version will have soon). It works with the latest Firefox version, with beautiful UI and support JS regex: https://addons.mozilla.org/en-US/firefox/addon/cross-domain-cors

For a case like this, always use RelativeLayouts. A LinearLayout is not intended for such a usage.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/db1_root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <!-- Place your layout here -->

    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_gravity="bottom"
        android:orientation="horizontal"
        android:paddingLeft="20dp"
        android:paddingRight="20dp" >

        <Button
            android:id="@+id/setup_macroSavebtn"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Save" />

        <Button
            android:id="@+id/setup_macroCancelbtn"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Cancel" />

        </LinearLayout>

</RelativeLayout>

As mentioned above you can wait for active connections to get closed:

private static void WaitForReady() {
    WebDriverWait wait = new WebDriverWait(webDriver, waitForElement);
    wait.Until(driver => (bool)((IJavaScriptExecutor)driver).ExecuteScript("return jQuery.active == 0"));
}

My observation is this is not reliable as data transfer happens very quickly. Much more time is consumed on data processing and rendering on the page and even jQuery.active == 0 data might not be yet on the page.

Much wiser is to use an explicit wait for element to be shown on the page, see some of the answers related to this.

The best situation is if your web application have some custom loader or indication that data is being processed. In this case you can just wait for this indication to hide.

Use a CipherOutputStream or CipherInputStream with a Cipher and your FileInputStream / FileOutputStream.

I would suggest something like Cipher.getInstance("AES/CBC/PKCS5Padding") for creating the Cipher class. CBC mode is secure and does not have the vulnerabilities of ECB mode for non-random plaintexts. It should be present in any generic cryptographic library, ensuring high compatibility.

Don't forget to use a Initialization Vector (IV) generated by a secure random generator if you want to encrypt multiple files with the same key. You can prefix the plain IV at the start of the ciphertext. It is always exactly one block (16 bytes) in size.

If you want to use a password, please make sure you do use a good key derivation mechanism (look up password based encryption or password based key derivation). PBKDF2 is the most commonly used Password Based Key Derivation scheme and it is present in most Java runtimes, including Android. Note that SHA-1 is a bit outdated hash function, but it should be fine in PBKDF2, and does currently present the most compatible option.

Always specify the character encoding when encoding/decoding strings, or you'll be in trouble when the platform encoding differs from the previous one. In other words, don't use String.getBytes() but use String.getBytes(StandardCharsets.UTF_8).

To make it more secure, please add cryptographic integrity and authenticity by adding a secure checksum (MAC or HMAC) over the ciphertext and IV, preferably using a different key. Without an authentication tag the ciphertext may be changed in such a way that the change cannot be detected.

Be warned that CipherInputStream may not report BadPaddingException, this includes BadPaddingException generated for authenticated ciphers such as GCM. This would make the streams incompatible and insecure for these kind of authenticated ciphers.

Try this property of TextView in your layout file..

android:ellipsize="end"
android:maxLines="1"

This is correct. You can also do :

A[] a = new A[] { new A("args"), new A("other args"), .. };

This syntax can also be used to create and initialize an array anywhere, such as in a method argument:

someMethod( new A[] { new A("args"), new A("other args"), . . } )

I stumbled over this thread searching for answer to similar case. Basically all answers are found, but it's still hard to extract the essentials from them.

Kinds of Access

Assume a class Foo probably derived from some other class(es) with probably more classes derived from it.

Then accessing

• from static method/getter of Foo
  • some probably overridden static method/getter:
    • this.method()
    • this.property
  • some probably overridden instance method/getter:
    • impossible by design
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • impossible by design
• from instance method/getter of Foo
  • some probably overridden static method/getter:
    • this.constructor.method()
    • this.constructor.property
  • some probably overridden instance method/getter:
    • this.method()
    • this.property
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • not possible by intention unless using some workaround:
      • Foo.prototype.method.call( this )
      • Object.getOwnPropertyDescriptor( Foo.prototype,"property" ).get.call(this);

Keep in mind that using this isn't working this way when using arrow functions or invoking methods/getters explicitly bound to custom value.

Background

• When in context of an instance's method or getter
  • this is referring to current instance.
  • super is basically referring to same instance, but somewhat addressing methods and getters written in context of some class current one is extending (by using the prototype of Foo's prototype).
  • definition of instance's class used on creating it is available per this.constructor.
• When in context of a static method or getter there is no "current instance" by intention and so
  • this is available to refer to the definition of current class directly.
  • super is not referring to some instance either, but to static methods and getters written in context of some class current one is extending.

After finding package

Looks like you called it 'ant build..xml'. ant automatically choose a file build.xml in the current directory, so it is enough to call 'ant' (if a default-target is defined) or 'ant target' (the target named target will be called).

With the call 'ant -p' you get a list of targets defined in your build.xml.

Edit: In the comment is shown the call 'ant -verbose build.xml'. To be correct, this has to be called as 'ant -verbose'. The file build.xml in the current directory will be used automatically. If it is needed to explicitly specify the buildfile (because it's name isn't build.xml for example), you have to specify the buildfile with the '-f'-option: 'ant -verbose -f build.xml'. I hope this helps.

I just want to add to the already accepted answer. I was stuck on this, but I was going a different route on handling the complete event. Rather than running await, I add a completed handler to the task.

Comments.AsAsyncAction().Completed += new AsyncActionCompletedHandler(CommentLoadComplete);

Where the event handler looks like this

private void CommentLoadComplete(IAsyncAction sender, AsyncStatus status )
{
    if (status == AsyncStatus.Canceled)
    {
        return;
    }
    CommentsItemsControl.ItemsSource = Comments.Result;
    CommentScrollViewer.ScrollToVerticalOffset(0);
    CommentScrollViewer.Visibility = Visibility.Visible;
    CommentProgressRing.Visibility = Visibility.Collapsed;
}

With this route, all the handling is already done for you, when the task is cancelled it just triggers the event handler and you can see if it was cancelled there.

The other methods are great but they don't preserve any prototype functions attached to init. To get around that you can do the following (inspired by the post from Nick Craver).

(function () {
    var old_prototype = init.prototype;
    var old_init = init;
    init = function () {
        old_init.apply(this, arguments);
        // Do something extra
    };
    init.prototype = old_prototype;
}) ();

No, image/jpg is not the same as image/jpeg.

You should use image/jpeg. Only image/jpeg is recognised as the actual mime type for JPEG files.

See https://tools.ietf.org/html/rfc3745, https://www.w3.org/Graphics/JPEG/ .

Serving the incorrect Content-Type of image/jpg to IE can cause issues, see http://www.bennadel.com/blog/2609-internet-explorer-aborts-images-with-the-wrong-mime-type.htm.

In Python 3 the dict.values() method returns a dictionary view object, not a list like it does in Python 2. Dictionary views have a length, can be iterated, and support membership testing, but don't support indexing.

To make your code work in both versions, you could use either of these:

{names[i]:value for i,value in enumerate(d.values())}

    or

values = list(d.values())
{name:values[i] for i,name in enumerate(names)}

By far the simplest, fastest way to do the same thing in either version would be:

dict(zip(names, d.values()))

Note however, that all of these methods will give you results that will vary depending on the actual contents of d. To overcome that, you may be able use an OrderedDict instead, which remembers the order that keys were first inserted into it, so you can count on the order of what is returned by the values() method.

//for dynamic elements - if you want it in ng-repeat do below code

angular.forEach($scope.data, function(value, key) {
     //add new value to object
    value.new_url  = "your url";
});

 <div ng-repeat="row in data"><a ng-href="{{ row.url_content }}"></a></div>

On Windows it ended up being that the port was already in use by IIS.

Stopping IIS (Right-click, Exit), resolved the issue.

var cultureEn = "en-US";
var monthEn = CultureInfo.CreateSpecificCulture(cultureEn).DateTimeFormat.GetAbbreviatedMonthName(month);
Console.WriteLine(monthEn);

Try nslookup google.com to determine if there's a DNS issue. 192.168.1.254 is your local network address and it looks like your system is using it as a DNS server. Is this your gateway/modem router as well? What happens when you try ping google.com. Can you browse to it on a Internet web browser?

In Xamarin.Android you can use these:

SupportActionBar.SetHomeButtonEnabled(true);
SupportActionBar.SetDisplayShowHomeEnabled(true);
SupportActionBar.SetDisplayUseLogoEnabled(true);
SupportActionBar.SetIcon(Resource.Drawable.ic_launcher);
SupportActionBar.SetDisplayShowTitleEnabled(false);

using Android.Support.V7.App.AppCompatActivity is required.

The pros and cons are pretty much identical.It depends on whether you want this or not.

Be careful, if MySQL timezone differs from your system time (for instance PHP), comparing the time or printing to the user will involve some tinkering.

That's work for me.

<ProgressBar
android:id="@+id/ProgressBar01" 
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminateTint="@color/black"/>

I did try giving access to the folders but that did not help. My solution was to make the below highlighted options in red selected for the logged in user

I tried as you mentioned, but only first parameter is going through and rest all are appearing in the server as undefined. I am passing JSONWebToken as part of header.

.ajax({
    url: 'api/outletadd',
    type: 'post',
    data: { outletname:outletname , addressA:addressA , addressB:addressB, city:city , postcode:postcode , state:state , country:country , menuid:menuid },
    headers: {
        authorization: storedJWT
    },
    dataType: 'json',
    success: function (data){
        alert("Outlet Created");
    },
    error: function (data){
        alert("Outlet Creation Failed, please try again.");        
    }

    });

Best? Well. probably not, But If you don't want to design something bespoke this is the best there is...

In order to generate release key hash you need to follow some easy steps.

1) Download Openssl

2) Make a openssl folder in C drive

3) Extract Zip files into this openssl folder created in C Drive.

4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin Folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin)

5) Open command prompt and give the path of JDK Bin folder in my case (C:\Program Files\Java\jdk1.7.0_40\bin).

6) Copy the following code and hit enter

keytool -exportcert -alias abcd-keystore D:\Projects\MyAppFolder\keystore.txt | C:\openssl\bin\openssl sha1 - binary | C:\openssl\bin\openssl base64 ex - keytool -exportcert -alias (your sing apk alias name enter here like my sign apk alian name is abcd )-keystore "signed apk generated keystore apth enter here" | "openssl bin folder path enter here" sha1 - binary | "openssl bin folder path enter here" base64

7) Now you need to enter password, Password = (enter your sign keystore password here)

8) you got keystore which are used for release app key hash

You can create a simple directive like this:

angular.module('myApp',[])
    .directive('myTooltip', function(){
        return {
            restrict: 'A',
            link: function(scope, element){
                element.tooltip();
            }
        }
    });

Then, add your custom directive where is necessary:

<button my-tooltip></button>

I was not sure to write it but maybe someone save a few hours:

mvn clean

may do the job if your whole configuration is already perfect!

I made some changes for backspace

        string pass = "";
        Console.Write("Enter your password: ");
        ConsoleKeyInfo key;

        do
        {
            key = Console.ReadKey(true);

            // Backspace Should Not Work
            if (key.Key != ConsoleKey.Backspace)
            {
                pass += key.KeyChar;
                Console.Write("*");
            }
            else
            {
                pass = pass.Remove(pass.Length - 1);
                Console.Write("\b \b");
            }
        }
        // Stops Receving Keys Once Enter is Pressed
        while (key.Key != ConsoleKey.Enter);

        Console.WriteLine();
        Console.WriteLine("The Password You entered is : " + pass);

Not sure if it'll work in all circumstances, but in our case, we were trying to override the describe function in Jest so that we can parse the name and skip the whole describe block if it met some criteria.

Here's what worked for us:

function describe( name, callback ) {
  if ( name.includes( "skip" ) )
    return this.describe.skip( name, callback );
  else
    return this.describe( name, callback );
}

Two things that are critical here:

1. We don't use an arrow function () =>.

   Arrow functions change the reference to this and we need that to be the file's this.

2. The use of this.describe and this.describe.skip instead of just describe and describe.skip.

Again, not sure it's of value to anybody but we originally tried to get away with Matthew Crumley's excellent answer but needed to make our method a function and accept params in order to parse them in the conditional.

I would suggest this:

e.pageX - this.getBoundingClientRect().left

This approach worked for me using the Material Components library:

In styles.xml:

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <!-- Your styles here -->

    <item name="toolbarStyle">@style/AppTheme.Toolbar</item>
</style>

<style name="AppTheme.Toolbar" parent="Widget.MaterialComponents.Toolbar">
    <item name="titleTextColor">@android:color/white</item>
</style>

To answer your question, let's assume that you are interested in a specific angular version and NOT in a specific angular-cli version (angular-cli is just a tool after all).

A reasonnable move is to keep your angular-cli version alligned with your angular version, otherwise you risk to stumble into incompatibilities issues. So getting the correct angular-cli version will lead you to getting the desired angular version.

From that assumption, your question is not about angular-cli, but about npm.

Here is the way to go:

[STEP 0 - OPTIONAL] If you're not sure of the angular-cli version installed in your environment, uninstall it.

npm uninstall -g @angular/cli

Then, run (--force flag might be required)

npm cache clean

or, if you're using npm > 5.

npm cache verify

[STEP 1] Install an angular-cli specific version

npm install -g @angular/[email protected]

[STEP 2] Create a project

ng new you-app-name

The resulting white app will be created in the desired angular version.

NOTE: I have not found any page displaying the compatibility matrix of angular and angular-cli. So I guess the only way to know what angular-cli version should be installed is to try various versions, create a new project and checkout the package.json to see which angular version is used.

Your first CSS selector—social.h2—is looking for the "social" element in the "h2", class, e.g.:

<social class="h2">

Class selectors are proceeded with a dot (.). Also, use a space () to indicate that one element is inside of another. To find an <h2> descendant of an element in the social class, try something like:

.social h2 {
  color: pink;
  font-size: 14px;
}

To get a better understanding of CSS selectors and how they are used to reference your HTML, I suggest going through the interactive HTML and CSS tutorials from CodeAcademy. I hope that this helps point you in the right direction.

Getting the ball rolling with this community wiki answer. Feel free to edit me with your improvements.

• ws WebSocket server and client for node.js. One of the fastest libraries if not the fastest one.

• websocket-node WebSocket server and client for node.js

• websocket-driver-node WebSocket server and client protocol parser node.js - used in faye-websocket-node

• faye-websocket-node WebSocket server and client for node.js - used in faye and sockjs

• socket.io WebSocket server and client for node.js + client for browsers + (v0 has newest to oldest fallbacks, v1 of Socket.io uses engine.io) + channels - used in stack.io. Client library tries to reconnect upon disconnection.

• sockjs WebSocket server and client for node.js and others + client for browsers + newest to oldest fallbacks

• faye WebSocket server and client for node.js and others + client for browsers + fallbacks + support for other server-side languages

• deepstream.io clusterable realtime server that handles WebSockets & TCP connections and provides data-sync, pub/sub and request/response

• socketcluster WebSocket server cluster which makes use of all CPU cores on your machine. For example, if you were to use an xlarge Amazon EC2 instance with 32 cores, you would be able to handle almost 32 times the traffic on a single instance.

• primus Provides a common API for most of the libraries above for easy switching + stability improvements for all of them.

When to use:

• use the basic WebSocket servers when you want to use the native WebSocket implementations on the clientside, beware of the browser incompatabilities

• use the fallback libraries when you care about browser fallbacks

• use the full featured libraries when you care about channels

• use primus when you have no idea about what to use, are not in the mood for rewriting your application when you need to switch frameworks because of changing project requirements or need additional connection stability.

Firecamp is a GUI testing environment for SocketIO, WS and all major real-time technology. Debug the real-time events while you're developing it.

Command from top-voted answer not work for me.

It got output:

This command works fine (group for /usr/local was admin already):

sudo chown -R $USER /usr/local

You can just use return to end the method's execution

In Kotlin you can add Textview as follows.

 val textView = TextView(activity).apply {
            layoutParams = LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.WRAP_CONTENT
            ).apply {
                setMargins(0, 20, 0, 0)
                setPadding(10, 10, 0, 10)
            }
            text = "SOME TEXT"
            setBackgroundColor(ContextCompat.getColor(this@MainActivity, R.color.colorPrimary))
            setTextColor(ContextCompat.getColor(this@MainActivity, R.color.colorPrimaryDark))
            textSize = 16.0f
            typeface = Typeface.defaultFromStyle(Typeface.BOLD)
        }

Hi according to our test between 2 different servers the results are as follows:

using curl for checking 10 .png files (each about 5 mb) was on average 5.7 secs. using header check for the same thing took average of 7.8 seconds!

So in our test curl was much faster if you have to check larger files!

our curl function is:

function remote_file_exists($url){
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_NOBODY, true);
    curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    if( $httpCode == 200 ){return true;}
    return false;
}

here is our header check sample:

function UR_exists($url){
   $headers=get_headers($url);
   return stripos($headers[0],"200 OK")?true:false;
}

This should do it for you - all your files will end up called Part1-Part500.

#!/bin/bash
FILENAME=10000.csv
HDR=$(head -1 $FILENAME)   # Pick up CSV header line to apply to each file
split -l 20 $FILENAME xyz  # Split the file into chunks of 20 lines each
n=1
for f in xyz*              # Go through all newly created chunks
do
   echo $HDR > Part${n}    # Write out header to new file called "Part(n)"
   cat $f >> Part${n}      # Add in the 20 lines from the "split" command
   rm $f                   # Remove temporary file
   ((n++))                 # Increment name of output part
done

//Global Variable

private int selectedPosition = -1;

 @Override
    public void onBindViewHolder(final CustomViewHolder customViewHolder, final int i) {

        final int position = i;
        final GetProductCatalouge.details feedItem = this.postBeanses.get(i);
        customViewHolder.lly_main.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                selectedPosition = i;
                notifyDataSetChanged();
            }
        });
        if (selectedPosition == i) {

          if (customViewHolder.lly_hsn_code.getVisibility() == View.VISIBLE) {

            customViewHolder.lly_hsn_code.setVisibility(View.GONE);
            customViewHolder.lly_sole.setVisibility(View.GONE);
            customViewHolder.lly_sole_material.setVisibility(View.GONE);

        } else {

            customViewHolder.lly_hsn_code.setVisibility(View.VISIBLE);
            customViewHolder.lly_sole.setVisibility(View.VISIBLE);
            customViewHolder.lly_sole_material.setVisibility(View.VISIBLE);
        }


        } else {
            customViewHolder.lly_hsn_code.setVisibility(View.GONE);
            customViewHolder.lly_sole.setVisibility(View.GONE);
            customViewHolder.lly_sole_material.setVisibility(View.GONE);
        }
}

Both means "every item in a set of two things". The two things being "left" and "right"

Check this may be helpful. Works fine for me. Code also covered daylight savings

    TimeZone tz = TimeZone.getTimeZone("Asia/Shanghai");
    Calendar cal = Calendar.getInstance();      
    // If needed in hours rather than milliseconds
    int LocalOffSethrs = (int) ((cal.getTimeZone().getRawOffset()) *(2.77777778 /10000000));        
    int ChinaOffSethrs = (int) ((tz.getRawOffset()) *(2.77777778 /10000000));       
    int dts = cal.getTimeZone().getDSTSavings();
    System.out.println("Local Time Zone : " + cal.getTimeZone().getDisplayName());
    System.out.println("Local Day Light Time Saving : " + dts);
    System.out.println("China Time : " + tz.getRawOffset());
    System.out.println("Local Offset Time from GMT: " + LocalOffSethrs);
    System.out.println("China Offset Time from GMT: " + ChinaOffSethrs);    
    // Adjust to GMT
    cal.add(Calendar.MILLISECOND,-(cal.getTimeZone().getRawOffset()));  
    // Adjust to Daylight Savings
    cal.add(Calendar.MILLISECOND, - cal.getTimeZone().getDSTSavings());
    // Adjust to Offset
    cal.add(Calendar.MILLISECOND, tz.getRawOffset());       
    Date dt = new Date(cal.getTimeInMillis());              
    System.out.println("After adjusting offset Acctual China Time :" + dt);

The answer below is related to this deprecation warning occurring in the Fragments tutorial on the Android developer website and may not be related to the posts above.

I used this code on the tutorial lesson and it did worked.

public void onAttach(Context context){
    super.onAttach(context);

    Activity activity = getActivity();

I was worried that activity maybe null as what the documentation states.

getActivity

FragmentActivity getActivity () Return the FragmentActivity this fragment is currently associated with. May return null if the fragment is associated with a Context instead.

But the onCreate on the main_activity clearly shows that the fragment was loaded and so after this method, calling get activity from the fragment will return the main_activity class.

getSupportFragmentManager().beginTransaction() .add(R.id.fragment_container, firstFragment).commit();

I hope I am correct with this. I am an absolute newbie.

You most likely get this message when the project points to an old location of the assembly where it no longer exists. Since you were able to build it once, the assembly has already been copied into your bin\Debug / bin\Release folders so your project can still find a copy.

If you open the references node of the project in your solution explorer, there should be a yellow icon next to the reference. Remove the reference and add it again from the correct location.

If you want to know the location it was referenced from, you'd have to open the .csproj file in a text editor and look for the HintPath for that assembly - the IDE for some reason does not show this information.

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

I put together a little test here:

\documentclass[10pt,twocolumn]{article}

\title{Article Title}

}
\date{\today}

\begin{document}

\maketitle

\begin{abstract}
\ldots
\end{abstract}

\section{Introduction}
\ldots

\end{document}

Things to note, the title, author and date fields are declared before \begin{document}. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn in the document class.

This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}. Here's a more detailed article on \LaTeX font sizes:

https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont

To italicize you can use {\it First Name} or \textit{First Name}.

Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.

The FOR loop worked well, I modified it a tiny bit:

#include<iostream>
using namespace std;
int main ()
{

    int sum = 0;
    int number;
    int numberitems;


    cout << "Enter number of items: \n";
    cin >> numberitems;

    for(int i=0;i<numberitems;i++)
    {
        cout << "Enter number: \n";
        cin >> number; 

        sum=sum+number;

    }
    cout<<"sum is: "<< sum<<endl;
}

HOWEVER, the WHILE loop has got some errors on line 11 (Count was not declared in this scope). What could be the issue? Also, if you would have a solution using DO,WHILE loop it would be wonderful. Thanks

To complement the preexisting, helpful answers with guidance of when to use which approach and a performance comparison.

• Outside of a pipeline^[1], use (PSv3+):

  $objects.Name

  as demonstrated in rageandqq's answer, which is both syntactically simpler and much faster.

  • Accessing a property at the collection level to get its members' values as an array is called member enumeration and is a PSv3+ feature.

  • Alternatively, in PSv2, use the foreach statement, whose output you can also assign directly to a variable:

    $results = foreach ($obj in $objects) { $obj.Name }

  • If collecting all output from a (pipeline) command in memory first is feasible, you can also combine pipelines with member enumeration; e.g.:

     (Get-ChildItem -File | Where-Object Length -lt 1gb).Name
    

  • Tradeoffs:

    • Both the input collection and output array must fit into memory as a whole.
    • If the input collection is itself the result of a command (pipeline) (e.g., (Get-ChildItem).Name), that command must first run to completion before the resulting array's elements can be accessed.

• In a pipeline, in case you must pass the results to another command, notably if the original input doesn't fit into memory as a whole, use:

  $objects | Select-Object -ExpandProperty Name

  • The need for -ExpandProperty is explained in Scott Saad's answer (you need it to get only the property value).
  • You get the usual pipeline benefits of the pipeline's streaming behavior, i.e. one-by-one object processing, which typically produces output right away and keeps memory use constant (unless you ultimately collect the results in memory anyway).
  • Tradeoff:
    • Use of the pipeline is comparatively slow.

For small input collections (arrays), you probably won't notice the difference, and, especially on the command line, sometimes being able to type the command easily is more important.

Here is an easy-to-type alternative, which, however is the slowest approach; it uses simplified ForEach-Object syntax called an operation statement (again, PSv3+): ; e.g., the following PSv3+ solution is easy to append to an existing command:

$objects | % Name      # short for: $objects | ForEach-Object -Process { $_.Name }

The PSv4+ .ForEach() array method, more comprehensively discussed in this article, is yet another, well-performing alternative, but note that it requires collecting all input in memory first, just like member enumeration:

# By property name (string):
$objects.ForEach('Name')

# By script block (more flexibility; like ForEach-Object)
$objects.ForEach({ $_.Name })

• This approach is similar to member enumeration, with the same tradeoffs, except that pipeline logic is not applied; it is marginally slower than member enumeration, though still noticeably faster than the pipeline.

• For extracting a single property value by name (string argument), this solution is on par with member enumeration (though the latter is syntactically simpler).

• The script-block variant ({ ... }) allows arbitrary transformations; it is a faster - all-in-memory-at-once - alternative to the pipeline-based ForEach-Object cmdlet (%).

Note: The .ForEach() array method, like its .Where() sibling (the in-memory equivalent of Where-Object), always returns a collection (an instance of [System.Collections.ObjectModel.Collection[psobject]]), even if only one output object is produced.
By contrast, member enumeration, Select-Object, ForEach-Object and Where-Object return a single output object as-is, without wrapping it in a collection (array).

Comparing the performance of the various approaches

Here are sample timings for the various approaches, based on an input collection of 10,000 objects, averaged across 10 runs; the absolute numbers aren't important and vary based on many factors, but it should give you a sense of relative performance (the timings come from a single-core Windows 10 VM:

Important

• The relative performance varies based on whether the input objects are instances of regular .NET Types (e.g., as output by Get-ChildItem) or [pscustomobject] instances (e.g., as output by Convert-FromCsv).
  The reason is that [pscustomobject] properties are dynamically managed by PowerShell, and it can access them more quickly than the regular properties of a (statically defined) regular .NET type. Both scenarios are covered below.

• The tests use already-in-memory-in-full collections as input, so as to focus on the pure property extraction performance. With a streaming cmdlet / function call as the input, performance differences will generally be much less pronounced, as the time spent inside that call may account for the majority of the time spent.

• For brevity, alias % is used for the ForEach-Object cmdlet.

General conclusions, applicable to both regular .NET type and [pscustomobject] input:

• The member-enumeration ($collection.Name) and foreach ($obj in $collection) solutions are by far the fastest, by a factor of 10 or more faster than the fastest pipeline-based solution.

• Surprisingly, % Name performs much worse than % { $_.Name } - see this GitHub issue.

• PowerShell Core consistently outperforms Windows Powershell here.

Timings with regular .NET types:

Conclusions:

• In PowerShell Core, .ForEach('Name') clearly outperforms .ForEach({ $_.Name }). In Windows PowerShell, curiously, the latter is faster, albeit only marginally so.

Conclusions:

• Note how with [pscustomobject] input .ForEach('Name') by far outperforms the script-block based variant, .ForEach({ $_.Name }).

• Similarly, [pscustomobject] input makes the pipeline-based Select-Object -ExpandProperty Name faster, in Windows PowerShell virtually on par with .ForEach({ $_.Name }), but in PowerShell Core still about 50% slower.

• In short: With the odd exception of % Name, with [pscustomobject] the string-based methods of referencing the properties outperform the scriptblock-based ones.

Source code for the tests:

Note:

• Download function Time-Command from this Gist to run these tests.

  • Assuming you have looked at the linked code to ensure that it is safe (which I can personally assure you of, but you should always check), you can install it directly as follows:

• Set $useCustomObjectInput to $true to measure with [pscustomobject] instances instead.

$count = 1e4 # max. input object count == 10,000
$runs  = 10  # number of runs to average 

# Note: Using [pscustomobject] instances rather than instances of 
#       regular .NET types changes the performance characteristics.
# Set this to $true to test with [pscustomobject] instances below.
$useCustomObjectInput = $false

# Create sample input objects.
if ($useCustomObjectInput) {
  # Use [pscustomobject] instances.
  $objects = 1..$count | % { [pscustomobject] @{ Name = "$foobar_$_"; Other1 = 1; Other2 = 2; Other3 = 3; Other4 = 4 } }

You can use

@PostConstruct
public void init() {
   // ...
}

Cookies are passed as HTTP headers, both in the request (client -> server), and in the response (server -> client).

You do not specify why you think it is wrong but I can se two dangers:

BETWEEN can be implemented differently in different databases sometimes it is including the border values and sometimes excluding, resulting in that 1 and 31 of january would end up NOTHING. You should test how you database does this.

Also, if RATE_DATE contains hours also 2010-01-31 might be translated to 2010-01-31 00:00 which also would exclude any row with an hour other that 00:00.

According to this post

You need to add the !important css modifier to your height percentages.

Hope this helps.

Add this function to your helper file and simply call.

function getRawQuery($sql){
        $query = str_replace(array('?'), array('\'%s\''), $sql->toSql());
        $query = vsprintf($query, $sql->getBindings());     
        return $query;
}

Output: "select * from user where status = '1' order by id desc limit 25 offset 0"

On Windows XP the path to the .gemrc file is

c:\Documents and Settings\All Users\Application Data\gemrc 

and this file is not created by default, you should create it yourself.

I had same problem and the quick fix is:

1. Remove bundle id from General tab of Xcode
2. Go to info.plist file and put bundle id for the Bundle identifier field.

Clean and run. That's it.

Relative Path is also ok:

java -Dlog4j.configuration=file:".\log4j.properties" -jar com.your-1.0-SNAPSHOT.jar

or

java -Dlog4j.configuration=file:".\log4j.xml" -jar com.your-1.0-SNAPSHOT.jar

my issue was (master|REBASE 1/1)

this command worked for me

 git rebase --skip

you can use rowSums

rowSums(data) should give you what you want.

Here are two approaches you can read raw resources using Kotlin.

You can get it by getting the resource id. Or, you can use string identifier in which you can programmatically change the filename with incrementation.

Found an XML transform stylesheet here (wayback machine link, site itself is in german)

The stylesheet added here could be helpful:

<xsl:stylesheet version="1.0"

<xsl:output method="text" encoding="iso-8859-1"/>

<xsl:strip-space elements="*" />

Perhaps you want to remove the quotes inside the xsl:if tags so it doesn't put your values into quotes, depending on where you want to use the CSV file.

You can set border properties on a tr element, but according to the CSS 2.1 specification, such properties have no effect in the separated borders model, which tends to be the default in browsers. Ref.: 17.6.1 The separated borders model. (The initial value of border-collapse is separate according to CSS 2.1, and some browsers also set it as default value for table. The net effect anyway is that you get separated border on almost all browsers unless you explicitly specifi collapse.)

Thus, you need to use collapsing borders. Example:

<style>
table { border-collapse: collapse; }
tr:nth-child(3) { border: solid thin; }
</style>

How I would write it:

var left: Node? = null

fun show() {
     val left = left ?: return
     queue.add(left) // no error because we return if it is null
}

If you define a color in your XML and want to use it to change background color or something this API is the one your are looking for:

 ((TextView) view).setBackgroundResource(R.drawable.your_color_here);

In my sample I used it for TestView

you could try:

<a href="#/controllerone">Controller One</a>||
<a href="#/controllerTwo">Controller Two</a>||
<a href="#/controllerThree">Controller Three</a>

<div>
    <div ng-view=""></div>
</div>

Don't write tests to get full coverage of your code. Write tests that guarantee your requirements. You may discover codepaths that are unnecessary. Conversely, if they are necessary, they are there to fulfill some kind of requirement; find it what it is and test the requirement (not the path).

Keep your tests small: one test per requirement.

Later, when you need to make a change (or write new code), try writing one test first. Just one. Then you'll have taken the first step in test-driven development.

If you are running on headless CI and are installing the Android SDK through command line, make sure to include the m2repository packages in the --filter argument:

android update sdk --no-ui --filter platform-tools,build-tools-19.0.1,android-19,extra-android-support,extra-android-m2repository,extra-google-m2repository

Update

As of Android SDK Manager rev. 22.6.4 this does not work anymore. Try this instead:

android list sdk --all

You will get a list of all available SDK packages. Look up the numerical values of the components from the first command above ("Google Repository" and others you might be missing).

Install the packages using their numerical values:

android update sdk --no-ui --all --filter <num>

Update #2 (Sept 2017)

With the "new" Android SDK tools that were released earlier this year, the android command is now deprecated, and similar functionality has been moved to a new tool called sdkmanager:

List installed components:

sdkmanager --list

Update installed components:

sdkmanager --update

Install a new component (e.g. build tools version 26.0.0):

sdkmanager 'build-tools;26.0.0'

One classic root cause for this message is:

• when the repo has been initialized (git init lis4368/assignments),
• but no commit has ever been made

Ie, if you don't have added and committed at least once, there won't be a local master branch to push to.

Try first to create a commit:

• either by adding (git add .) then git commit -m "first commit"
  (assuming you have the right files in place to add to the index)
• or by create a first empty commit: git commit --allow-empty -m "Initial empty commit"

And then try git push -u origin master again.

See "Why do I need to explicitly push a new branch?" for more.

this few lines are the simple answer for this question in sql server.

WITH mycte AS
(
  SELECT CAST('2011-01-01' AS DATETIME) DateValue
  UNION ALL
  SELECT  DateValue + 1
  FROM    mycte   
  WHERE   DateValue + 1 < '2021-12-31'
)

SELECT  DateValue
FROM    mycte
OPTION (MAXRECURSION 0)

First point is- showing multiple popups is not desirable in terms of usability.

But you can achieve it by using multiple popup names

var newwindow;
function createPop(url, name)
{    
   newwindow=window.open(url,name,'width=560,height=340,toolbar=0,menubar=0,location=0');  
   if (window.focus) {newwindow.focus()}
}

Better approach will be showing both in a single page in two different iFrames or Divs.

Update:

So I will suggest to create a new tab in the test.aspx page to show the report, instead of replacing the image content and placing the pdf.

With a simple for loop:

var testimonials= $('.testimonial');
for (var i = 0; i < testimonials.length; i++) {
  // Using $() to re-wrap the element.
  $(testimonials[i]).text('a');
}

You can use string operators:

$ foo=1:2:3:4:5
$ echo ${foo##*:}
5

This trims everything from the front until a ':', greedily.

${foo  <-- from variable foo
  ##   <-- greedy front trim
  *    <-- matches anything
  :    <-- until the last ':'
 }

I prefer

(!$mentor)

Is more effective and accurate

Here goes mine, it's self contained and versatile, as well as efficient, it grows or shrinks buffers as needed in each recursion

void strreplace(char *src, char *str, char *rep)
{
    char *p = strstr(src, str);
    if (p)
    {
        int len = strlen(src)+strlen(rep)-strlen(str);
        char r[len];
        memset(r, 0, len);
        if ( p >= src ){
            strncpy(r, src, p-src);
            r[p-src]='\0';
            strncat(r, rep, strlen(rep));
            strncat(r, p+strlen(str), p+strlen(str)-src+strlen(src));
            strcpy(src, r);
            strreplace(p+strlen(rep), str, rep);
        }
    }
}

For versions of PHP prior to PHP 5.4.0:

if(session_id() == '') {
    // session isn't started
}

Though, IMHO, you should really think about refactoring your session management code if you don't know whether or not a session is started...

That said, my opinion is subjective, and there are situations (examples of which are described in the comments below) where it may not be possible to know if the session is started.

Our variable:

Map<String, List<Integer>> map = new HashMap<String, List<Integer>>();

To store:

map.put("mango", new ArrayList<Integer>(Arrays.asList(0, 4, 8, 9, 12)));

To add numbers one and one, you can do something like this:

String key = "mango";
int number = 42;
if (map.get(key) == null) {
    map.put(key, new ArrayList<Integer>());
}
map.get(key).add(number);

In Java 8 you can use putIfAbsent to add the list if it did not exist already:

map.putIfAbsent(key, new ArrayList<Integer>());
map.get(key).add(number);

Use the map.entrySet() method to iterate on:

for (Entry<String, List<Integer>> ee : map.entrySet()) {
    String key = ee.getKey();
    List<Integer> values = ee.getValue();
    // TODO: Do something.
}

You can also use functions with $filter('filter'):

var foo = $filter('filter')($scope.results.subjects, function (item) {
  return item.grade !== 'A';
});

Since I actually really needed this solution, and the typical baseline solution (focus the input - then set the value equal to itself) doesn't work cross-browser, I spent some time tweaking and editing everything to get it working. Building upon @kd7's code here's what I've come up with.

Enjoy! Works in IE6+, Firefox, Chrome, Safari, Opera

Cross-browser caret positioning technique (example: moving the cursor to the END)

// ** USEAGE ** (returns a boolean true/false if it worked or not)
// Parameters ( Id_of_element, caretPosition_you_want)

setCaretPosition('IDHERE', 10); // example

The meat and potatoes is basically @kd7's setCaretPosition, with the biggest tweak being if (el.selectionStart || el.selectionStart === 0), in firefox the selectionStart is starting at 0, which in boolean of course is turning to False, so it was breaking there.

In chrome the biggest issue was that just giving it .focus() wasn't enough (it kept selecting ALL of the text!) Hence, we set the value of itself, to itself el.value = el.value; before calling our function, and now it has a grasp & position with the input to use selectionStart.

function setCaretPosition(elemId, caretPos) {
    var el = document.getElementById(elemId);

    el.value = el.value;
    // ^ this is used to not only get "focus", but
    // to make sure we don't have it everything -selected-
    // (it causes an issue in chrome, and having it doesn't hurt any other browser)

    if (el !== null) {

        if (el.createTextRange) {
            var range = el.createTextRange();
            range.move('character', caretPos);
            range.select();
            return true;
        }

        else {
            // (el.selectionStart === 0 added for Firefox bug)
            if (el.selectionStart || el.selectionStart === 0) {
                el.focus();
                el.setSelectionRange(caretPos, caretPos);
                return true;
            }

            else  { // fail city, fortunately this never happens (as far as I've tested) :)
                el.focus();
                return false;
            }
        }
    }
}

});

(EN) On the server, you can get your data as - $_POST ['data__value']; For example, to get the first_name value on the server, write:

$test = json_decode( $_POST['data__value'] );
echo $test->first_name;

Recent updates to ggplot (0.9.2+) have overhauled the syntax for themes. Most notably, opts() is now deprecated, having been replaced by theme(). Sandy's answer will still (as of Jan '12) generates a chart, but causes R to throw a bunch of warnings.

Here's updated code reflecting current ggplot syntax:

library(ggplot2)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

#base ggplot object
p <- ggplot(df, aes(x = a, y = b))

p +
  #plots the points
  geom_point() +

  #theme with white background
  theme_bw() +

  #eliminates background, gridlines, and chart border
  theme(
    plot.background = element_blank(),
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(),
    panel.border = element_blank()
  ) +

  #draws x and y axis line
  theme(axis.line = element_line(color = 'black'))

generates:

If an expression involving the Boolean & operator is evaluated, both operands are evaluated. Then the & operator is applied to the operand.

When an expression involving the && operator is evaluated, the first operand is evaluated. If the first operand evaluates to false, the evaluation of the second operand is skipped.

If the first operand returns a value of true then the second operand is evaluated. If the second operand returns a value of true then && operator is then applied to the first and second operands.

Similar for | and ||.

In order to match the vector lenght and angle with the x,y coordinates of the plot, you can use to following options to plt.quiver:

plt.figure(figsize=(5,2), dpi=100)
plt.quiver(0,0,250,100, angles='xy', scale_units='xy', scale=1)
plt.xlim(0,250)
plt.ylim(0,100)

You could implement a onActivityResult in Class B as well and launch Class C using startActivityForResult. Once you get the result in Class B then set the result there (for Class A) based on the result from Class C. I haven't tried this out but I think this should work.

Another thing to look out for is that Activity A should not be a singleInstance activity. For startActivityForResult to work your Class B needs to be a sub activity to Activity A and that is not possible in a single instance activity, the new Activity (Class B) starts in a new task.

The printf() family of functions uses % character as a placeholder. When a % is encountered, printf reads the characters following the % to determine what to do:

%s - Take the next argument and print it as a string
%d - Take the next argument and print it as an int

See this Wikipedia article for a nice picture: printf format string

The \n at the end of the string is for a newline/carriage-return character.

The Provider piece must be Provider=Microsoft.ACE.OLEDB.12.0 if your target database is ACCDB format. Provider=Microsoft.Jet.OLEDB.4.0 only works for the older MDB format.

You shouldn't even need Access installed if you're running 32 bit Windows. Jet 4 is included as part of the operating system. If you're using 64 bit Windows, Jet 4 is not included, but you still wouldn't need Access itself installed. You can install the Microsoft Access Database Engine 2010 Redistributable. Make sure to download the matching version (AccessDatabaseEngine.exe for 32 bit Windows, or AccessDatabaseEngine_x64.exe for 64 bit).

You can avoid the issue about which ADO version reference by using late binding, which doesn't require any reference.

Dim conn As Object
Set conn = CreateObject("ADODB.Connection")

Then assign your ConnectionString property to the conn object. Here is a quick example which runs from a code module in Excel 2003 and displays a message box with the row count for MyTable. It uses late binding for the ADO connection and recordset objects, so doesn't require setting a reference.

Public Sub foo()
    Dim cn As Object
    Dim rs As Object
    Dim strSql As String
    Dim strConnection As String
    Set cn = CreateObject("ADODB.Connection")
    strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "Data Source=C:\Access\webforums\whiteboard2003.mdb"
    strSql = "SELECT Count(*) FROM MyTable;"
    cn.Open strConnection
    Set rs = cn.Execute(strSql)
    MsgBox rs.fields(0) & " rows in MyTable"
    rs.Close
    Set rs = Nothing
    cn.Close
    Set cn = Nothing
End Sub

If this answer doesn't resolve the problem, edit your question to show us the full connection string you're trying to use and the exact error message you get in response for that connection string.

I think VonC's answer is probably what you want, but here's a way to do a selective "git apply":

git show stash@{0}:MyFile.txt > MyFile.txt

Intent myIntent = new Intent(MainActivity.this, Katra_home.class);
startActivity(myIntent);

This Should the perfect one :)

Put the varible in an array and Use a for Loop to assign the same value to multiple variables.

  myArray[moveUP, moveDown, moveLeft];

    for(var i = 0; i < myArray.length; i++){

        myArray[i] = true;

    }

I followed the below Steps. It worked for me.

list_of_dicts.sort(key=operator.itemgetter('age'))

Also make sure to update your Oracle VM Virtual Box. I tried everything but later realized that the issue was due to the use of older version of Virtual Box.

From Apache Commons library:

import org.apache.commons.lang3.StringUtils

Use:

StringUtils.join(slist, ',');

Another similar question and answer here

I have also used a non-generic version, using the new keyword:

public interface IMetadata
{
    Type DataType { get; }

    object Data { get; }
}

public interface IMetadata<TData> : IMetadata
{
    new TData Data { get; }
}

Explicit interface implementation is used to allow both Data members:

public class Metadata<TData> : IMetadata<TData>
{
    public Metadata(TData data)
    {
       Data = data;
    }

    public Type DataType
    {
        get { return typeof(TData); }
    }

    object IMetadata.Data
    {
        get { return Data; }
    }

    public TData Data { get; private set; }
}

You could derive a version targeting value types:

public interface IValueTypeMetadata : IMetadata
{

}

public interface IValueTypeMetadata<TData> : IMetadata<TData>, IValueTypeMetadata where TData : struct
{

}

public class ValueTypeMetadata<TData> : Metadata<TData>, IValueTypeMetadata<TData> where TData : struct
{
    public ValueTypeMetadata(TData data) : base(data)
    {}
}

This can be extended to any kind of generic constraints.

You cannot have the WHERE clause in an INSERT statement.

insert into table1(data) VALUES(:data) where sno ='45830'

Should be

insert into table1(data) VALUES(:data)

Update: You have removed that from your code (I assume you copied the code in wrong). You want to increase your allowed packet size:

SET GLOBAL max_allowed_packet=32M

Change the 32M (32 megabytes) up/down as required. Here is a link to the MySQL documentation on the subject.

You can also use ISNULL and a select statement to get this result

SELECT
Table1.ID,
ISNULL((SELECT 'TRUE' FROM TABLE2 WHERE TABLE2.ID = TABEL1.ID),'FALSE') AS columName,
etc
FROM TABLE1

This one shows SQL that is currently "ACTIVE":-

select S.USERNAME, s.sid, s.osuser, t.sql_id, sql_text
from v$sqltext_with_newlines t,V$SESSION s
where t.address =s.sql_address
and t.hash_value = s.sql_hash_value
and s.status = 'ACTIVE'
and s.username <> 'SYSTEM'
order by s.sid,t.piece
/

This shows locks. Sometimes things are going slow, but it's because it is blocked waiting for a lock:

select
  object_name, 
  object_type, 
  session_id, 
  type,         -- Type or system/user lock
  lmode,        -- lock mode in which session holds lock
  request, 
  block, 
  ctime         -- Time since current mode was granted
from
  v$locked_object, all_objects, v$lock
where
  v$locked_object.object_id = all_objects.object_id AND
  v$lock.id1 = all_objects.object_id AND
  v$lock.sid = v$locked_object.session_id
order by
  session_id, ctime desc, object_name
/

This is a good one for finding long operations (e.g. full table scans). If it is because of lots of short operations, nothing will show up.

COLUMN percent FORMAT 999.99 

SELECT sid, to_char(start_time,'hh24:mi:ss') stime, 
message,( sofar/totalwork)* 100 percent 
FROM v$session_longops
WHERE sofar/totalwork < 1
/

From the "View" menu, select "Workspaces". You'll see all of the workspaces you've created. Select the workspaces you want to delete and click "Edit" -> "Delete Workspace", or right-click and select "Delete Workspace". If the workspace is "locked" to prevent changes, you'll get an error message.

To unlock the workspace, click "Edit" (or right-click and click "Edit Workspace") to pull up the workspace editor, uncheck the "locked" checkbox, and save your changes. You can delete the workspace once it's unlocked.

In my experience, the workspace will continue to be shown in the drop-down list until you click on it, at which point p4v will figure out you've deleted it and remove it from the list.

I think its good to keep the Label and not to use placeholder as mentioned above. Its good for UX as explain here: https://www.smashingmagazine.com/2018/03/ux-contact-forms-essentials-conversions/

Here example with Label inside Input fields: codepen.io/jdax/pen/mEBJNa

You should always do server side validaton as well.

public bool IsValidEmailAddress(string email)
{
    try
    {
        var emailChecked = new System.Net.Mail.MailAddress(email);
        return true;
    }
    catch
    {
        return false;
    }
}

UPDATE

You can also use the EmailAddressAttribute in System.ComponentModel.DataAnnotations. Then there is no need for a try-catch to it's a cleaner solution.

public bool IsValidEmailAddress(string email)
{
    if (!string.IsNullOrEmpty(email) && new EmailAddressAttribute().IsValid(email))
        return true;
    else
        return false;
}

Note that the IsNullOrEmpty check is also needed otherwise a null value will return true.

The order of the importing was the reason why I was having issues:

a.py:

############
# this is a problem
# move this to below
#############
from b import NewThing

class ProblemThing(object):
    pass

class A(object):
   ###############
   # add it here
   # from b import NewThing
   ###############
   nt = NewThing()
   pass

b.py:

from a import ProblemThing

class NewThing(ProblemThing):
    pass

Just another example of how it might look, similar to RichieHindie's answer, but with classes.

Here is the example to understand the difference

int i=10;
printf("%d %d",i++,++i);

output: 10 12/11 11 (depending on the order of evaluation of arguments to the printf function, which varies across compilers and architectures)

Explanation: i++->i is printed, and then increments. (Prints 10, but i will become 11) ++i->i value increments and prints the value. (Prints 12, and the value of i also 12)

What about:

#region Using Statements
using System;
using System.Xml;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XmlDocument doc = new XmlDocument( );

        //(1) the xml declaration is recommended, but not mandatory
        XmlDeclaration xmlDeclaration = doc.CreateXmlDeclaration( "1.0", "UTF-8", null );
        XmlElement root = doc.DocumentElement;
        doc.InsertBefore( xmlDeclaration, root );

        //(2) string.Empty makes cleaner code
        XmlElement element1 = doc.CreateElement( string.Empty, "body", string.Empty );
        doc.AppendChild( element1 );

        XmlElement element2 = doc.CreateElement( string.Empty, "level1", string.Empty );
        element1.AppendChild( element2 );

        XmlElement element3 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text1 = doc.CreateTextNode( "text" );
        element3.AppendChild( text1 );
        element2.AppendChild( element3 );

        XmlElement element4 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text2 = doc.CreateTextNode( "other text" );
        element4.AppendChild( text2 );
        element2.AppendChild( element4 );

        doc.Save( "D:\\document.xml" );
    }
}

_{(1) Does a valid XML file require an xml declaration?
(2) What is the difference between String.Empty and “” (empty string)?}

The result is:

<?xml version="1.0" encoding="UTF-8"?>
<body>
  <level1>
    <level2>text</level2>
    <level2>other text</level2>
  </level1>
</body>

But I recommend you to use LINQ to XML which is simpler and more readable like here:

#region Using Statements
using System;
using System.Xml.Linq;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XDocument doc = new XDocument( new XElement( "body", 
                                           new XElement( "level1", 
                                               new XElement( "level2", "text" ), 
                                               new XElement( "level2", "other text" ) ) ) );
        doc.Save( "D:\\document.xml" );
    }
}

Press Ctrl-a then : and then type

scrollback 10000

to get a 10000 line buffer, for example.

You can also set the default number of scrollback lines by adding

defscrollback 10000

to your ~/.screenrc file.

To scroll (if your terminal doesn't allow you to by default), press Ctrl-a ESC and then scroll (with the usual Ctrl-f for next page or Ctrl-a for previous page, or just with your mouse wheel / two-fingers). To exit the scrolling mode, just press ESC.

Another tip: Ctrl-a i shows your current buffer setting.

(I do realise the question is old, but it's among the top hits on Google.)

A common situation where you want to know the response code is in exception handling. As of C# 7, you can use pattern matching to actually only enter the catch clause if the exception matches your predicate:

catch (WebException ex) when (ex.Response is HttpWebResponse response)
{
     doSomething(response.StatusCode)
}

This can easily be extended to further levels, such as in this case where the WebException was actually the inner exception of another (and we're only interested in 404):

catch (StorageException ex) when (ex.InnerException is WebException wex && wex.Response is HttpWebResponse r && r.StatusCode == HttpStatusCode.NotFound)

Finally: note how there's no need to re-throw the exception in the catch clause when it doesn't match your criteria, since we don't enter the clause in the first place with the above solution.

The working version of your code (from the errors pointed out by BoltClock):

<?php
$date = '2011-01-01';
$timestamp = strtotime($date);
$weekday= date("l", $timestamp );
$normalized_weekday = strtolower($weekday);
echo $normalized_weekday ;
if (($normalized_weekday == "saturday") || ($normalized_weekday == "sunday")) {
    echo "true";
} else {
    echo "false";
}

?>

The stray "{" is difficult to see, especially without a decent PHP editor (in my case). So I post the corrected version here.

if you are using IIS, maybe you should try
"application pools" --> "DefaultAppPool" --> "application pools default value" --> "32-Bit-application-activ" --> set false

In simple terms,

1. static : static variables are associated with the class, rather than with any object. Every instance of the class shares a class variable, which is in one fixed location in memory

2. volatile: This keyword is applicable to both class and instance variables.

Using volatile variables reduces the risk of memory consistency errors, because any write to a volatile variable establishes a happens-before relationship with subsequent reads of that same variable. This means that changes to a volatile variable are always visible to other threads

Have a look at this article by Javin Paul to understand volatile variables in a better way.

In absence of volatile keyword, the value of variable in each thread's stack may be different. By making the variable as volatile, all threads will get same value in their working memory and memory consistency errors have been avoided.

Here the term variable can be either static (class) variable or instance (object) variable.

Regarding your query :

Anyway a static variable value is also going to be one value for all threads, then why should we go for volatile?

If I need instance variable in my application, I can't use static variable. Even in case of static variable, consistency is not guaranteed due to Thread cache as shown in the diagram.

Using volatile variables reduces the risk of memory consistency errors, because any write to a volatile variable establishes a happens-before relationship with subsequent reads of that same variable. This means that changes to a volatile variable are always visible to other threads.

What's more, it also means that when a thread reads a volatile variable, it sees not just the latest change to the volatile, but also the side effects of the code that led up the change => memory consistency errors are still possible with volatile variables. To avoid side effects, you have to use synchronized variables. But there is a better solution in java.

Using simple atomic variable access is more efficient than accessing these variables through synchronized code

Some of the classes in the java.util.concurrent package provide atomic methods that do not rely on synchronization.

Refer to this high level concurrency control article for more details.

Especially have a look at Atomic variables.

Here is a short example, the C++ way using rdbuf. I got this from the web. I can't find my original source on this:

#include <fstream>
#include <iostream>

int main () 
{
  std::ifstream f1 ("C:\\me.txt",std::fstream::binary);

  std::ofstream f2 ("C:\\me2.doc",std::fstream::trunc|std::fstream::binary);

  f2<<f1.rdbuf();

  return 0;
}

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

You can use:

<input (input)="saverange()>

Above solution does not work for me , I have tried following and it is working in all browsers.

simply made a fake ajax call, it will make a entry into referer header.

var request;
if (window.XMLHttpRequest) { // Mozilla, Safari, ...
    request = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE
    try {
        request = new ActiveXObject('Msxml2.XMLHTTP');
    } catch (e) {
        try {
            request = new ActiveXObject('Microsoft.XMLHTTP');
        } catch (e) {}
    }
}
request.open("GET", url, true);
request.send();

Instead of .* use .\{-}.

%s/style=".\{-}"//g

Use a .gitignore file. This allows you to ignore certain files. http://git-scm.com/docs/gitignore

Here's an example Eclipse one, which handles your classpath and project files: https://github.com/github/gitignore/blob/master/Global/Eclipse.gitignore

Create a new directory, and do a clone instead.

git clone (address of origin) (name of branch)

I struggled like mad, but this is actually the right answer. For what it is worth, what I missed was is this:

1. As others say, one can't create the CustomUI ribbon with VBA, however, you don't need to!
2. The idea is you create your xml Ribbon code using Excel's File > Options > Customize Ribbon, and then export the Ribbon to a .customUI file (it's just a txt file, with xml in it)
3. Now comes the trick: you can include the .customUI code in your .xlsm file using the MS tool they refer to here, by copying the code from the .customUI file
4. Once it is included in the .xlsm file, every time you open it, the ribbon you defined is added to the user's ribbon - but do use < ribbon startFromScratch="false" > or you lose the rest of the ribbon. On exit-ing the workbook, the ribbon is removed.
5. From here on it is simple, create your ribbon, copy the xml code that is specific to your ribbon from the .customUI file, and place it in a wrapper as shown above (...< tabs> your xml < /tabs...)

By the way the page that explains it on Ron's site is now at http://www.rondebruin.nl/win/s2/win002.htm

And here is his example on how you enable /disable buttons on the Ribbon http://www.rondebruin.nl/win/s2/win013.htm

For other xml examples of ribbons please also see http://msdn.microsoft.com/en-us/library/office/aa338202%28v=office.12%29.aspx

I feel like you're trying to solve the wrong problem here. Shouldn't you be trying to make the ssh daemons more stable? Try running something like monit, which will check to see if the daemon is running and restart it if it isn't (giving you time to find the root problem behind sshd shutting down on you). Or is the network service troublesome? Try looking at man ifup. Does the Whole Damn Thing just like to shut down on you? Well, that's a bigger problem ... try looking at your logs (start with syslog) to find hardware failures or services that are shutting your boxen down (maybe a temperature monitor?).

Making your scripts fault tolerant is great, but you might also want to make your boxen fault tolerant.

The max length of a varchar is subject to the max row size in MySQL, which is 64KB (not counting BLOBs):

VARCHAR(65535)

However, note that the limit is lower if you use a multi-byte character set:

VARCHAR(21844) CHARACTER SET utf8

Here are some examples:

The maximum row size is 65535, but a varchar also includes a byte or two to encode the length of a given string. So you actually can't declare a varchar of the maximum row size, even if it's the only column in the table.

mysql> CREATE TABLE foo ( v VARCHAR(65534) );
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

But if we try decreasing lengths, we find the greatest length that works:

mysql> CREATE TABLE foo ( v VARCHAR(65532) );
Query OK, 0 rows affected (0.01 sec)

Now if we try to use a multibyte charset at the table level, we find that it counts each character as multiple bytes. UTF8 strings don't necessarily use multiple bytes per string, but MySQL can't assume you'll restrict all your future inserts to single-byte characters.

mysql> CREATE TABLE foo ( v VARCHAR(65532) ) CHARSET=utf8;
ERROR 1074 (42000): Column length too big for column 'v' (max = 21845); use BLOB or TEXT instead

In spite of what the last error told us, InnoDB still doesn't like a length of 21845.

mysql> CREATE TABLE foo ( v VARCHAR(21845) ) CHARSET=utf8;
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

This makes perfect sense, if you calculate that 21845*3 = 65535, which wouldn't have worked anyway. Whereas 21844*3 = 65532, which does work.

mysql> CREATE TABLE foo ( v VARCHAR(21844) ) CHARSET=utf8;
Query OK, 0 rows affected (0.32 sec)

You can also use viewport-percentage lengths to achieve this:

5.1.2. Viewport-percentage lengths: the ‘vw’, ‘vh’, ‘vmin’, ‘vmax’ units

The viewport-percentage lengths are relative to the size of the initial containing block. When the height or width of the initial containing block is changed, they are scaled accordingly.

Where 100vh represents the height of the viewport, and likewise 100vw represents the width.

Example Here

body {_x000D_
    margin: 0;            /* Reset default margin */_x000D_
}_x000D_
iframe {_x000D_
    display: block;       /* iframes are inline by default */_x000D_
    background: #000;_x000D_
    border: none;         /* Reset default border */_x000D_
    height: 100vh;        /* Viewport-relative units */_x000D_
    width: 100vw;_x000D_
}

<iframe></iframe>

This is supported in most modern browsers - support can be found here.

I'll just leave this here for people interested in an implementation with no dependencies.

inline int
stringLength (char *String)
    {
    int Count = 0;
    while (*String ++) ++ Count;
    return Count;
    }

inline int
stringToInt (char *String)
    {
    int Integer = 0;
    int Length = stringLength(String);
    for (int Caret = Length - 1, Digit = 1; Caret >= 0; -- Caret, Digit *= 10)
        {
        if (String[Caret] == '-') return Integer * -1;
        Integer += (String[Caret] - '0') * Digit;
        }

    return Integer;
    }

Works with negative values, but can't handle non-numeric characters mixed in between (should be easy to add though). Integers only.

// Get first three characters
string sub = input.Substring(0, 3);
Console.WriteLine("Substring: {0}", sub); // Output One. 

string sub = input.Substring(6, 5);
Console.WriteLine("Substring: {0}", sub); //You'll get output: Three

Here is one way to calculate log return using .shift(). And the result is similar to but not the same as the gross return calculated by pct_change(). Can you upload a copy of your sample data (dropbox share link) to reproduce the inconsistency you saw?

import pandas as pd
import numpy as np

np.random.seed(0)
df = pd.DataFrame(100 + np.random.randn(100).cumsum(), columns=['price'])
df['pct_change'] = df.price.pct_change()
df['log_ret'] = np.log(df.price) - np.log(df.price.shift(1))

Out[56]: 
       price  pct_change  log_ret
0   101.7641         NaN      NaN

[100 rows x 3 columns]

You can only use - on the numeric entries, so you can use decreasing and negate the ones you want in increasing order:

DT[order(x,-v,decreasing=TRUE),]
      x y v
 [1,] c 1 7
 [2,] c 3 8
 [3,] c 6 9
 [4,] b 1 1
 [5,] b 3 2
 [6,] b 6 3
 [7,] a 1 4
 [8,] a 3 5
 [9,] a 6 6

You can use other ports like the following:

rails server -p 3001

Normally in your terminal you can try Ctrl + C to shutdown the server.

The other way to kill the Ruby on Rails default server (which is WEBrick) is:

kill -INT $(cat tmp/pids/server.pid)

In your terminal to find out the PID of the process:

$ lsof -wni tcp:3000

Then, use the number in the PID column to kill the process:

For example:

$ kill -9 PID

And some of the other answers i found is:

To stop the rails server while it's running, press:

CTRL-C
CTRL-Z

You will get control back to bash. Then type (without the $):

$ fg

And this will go back into the process, and then quit out of Rails s properly.

It's a little annoying, but this sure beats killing the process manually. It's not too bad and it's the best I could figure out.

Updated answer:

You can use killall -9 rails to kill all running apps with "rails" in the name.

killall -9 rails

You would do something like this to get the path "Data\ich_will.mp3" inside your application environments folder.

string fileName = "ich_will.mp3";
string path = Path.Combine(Environment.CurrentDirectory, @"Data\", fileName);

In my case it would return the following:

C:\MyProjects\Music\MusicApp\bin\Debug\Data\ich_will.mp3

I use Path.Combine and Environment.CurrentDirectory in my example. These are very useful and allows you to build a path based on the current location of your application. Path.Combine combines two or more strings to create a location, and Environment.CurrentDirectory provides you with the working directory of your application.

The working directory is not necessarily the same path as where your executable is located, but in most cases it should be, unless specified otherwise.

What exactly is the structure of your HTML?

The previous CSS will work if the HTML is as such:

CSS

.foo:nth-child(2)

HTML

<div>
 <div class="foo"></div>
 <div class="foo">Find me</div>
...
</div>

But if you have the following HTML it will not work.

<div>
 <div class="other"></div>
 <div class="foo"></div>
 <div class="foo">Find me</div>
 ...
</div>

Simple put, there is no selector for the getting the index of the matches from the rest of the selector before it.

I'm not 100% sure what your NonIntersect method is supposed to do (regarding set theory) - is it
B \ A (everything from B that does not occur in A)?
If yes, then you should be able to use the Except operation (B.Except(A)).

Here is my object inspector that is more readable. Because the code takes to long to write down here you can download it at http://etto-aa-js.googlecode.com/svn/trunk/inspector.js

Use like this :

document.write(inspect(object));

You need to uninstall it because you are using a different signature than the original. If it is not working it might be because it is still installed for another user on the device. To completely uninstall, go to Settings -> Apps -> (specific app)-> Options (the three dots on top right) -> Uninstall for all users.

I am also got this issue that time already installed ionic app(same package name) remove from my phone after that working perfectly.

You could create an extension function:

Round Float value:

fun Float.round(decimals: Int = DIGITS): Float {
    var multiplier = 1.0f
    repeat(decimals) { multiplier *= 10 }
    return round(this * multiplier) / multiplier
}

Method's usage:

(0.0f .. 1.0f).step(.1f).forEach { System.out.println("value: $it") }

Output:

value: 0.0 value: 0.1 value: 0.2 value: 0.3 value: 0.4 value: 0.5 value: 0.6 value: 0.7 value: 0.8 value: 0.9 value: 1.0

Use android:weightSum property to the parent LinearLayout and give value 3. Then in the children LinearLayout use android:layout_weight 2 and 1 respectively. Then in the First Chil LinearLayout use android:layout_gravity="center_vertical". As shown in the following code

<LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:weightSum="3"
                    android:orientation="horizontal">

                    <LinearLayout
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_weight="2"
                        android:layout_gravity="center_vertical"
                        android:orientation="horizontal">
                        <TextView
                            android:id="@+id/status_text"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:text="00"
                            android:textColor="@color/red"
                            android:textSize="@dimen/default_text_size"
                            />
                          <TextView
                            android:id="@+id/status_text"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:text="00"
                            android:textColor="@color/red"
                            android:textSize="@dimen/default_text_size"
                            />
                    </LinearLayout>
                    <LinearLayout
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_weight="1">
                        <Button
                          android:layout_width="fill_parent"
                          android:layout_height="wrap_content"
                          android:text="Delete"/>
                    </LinearLayout>
                </LinearLayout>

Maybe you can use TextFX plugins

In TextFX, go to textfx edit ? delete blank lines

Obviously '12/01/2012 13:16:32.000' doesn't match 'DD-MON-YYYY hh24:mi' format.

Update:

You need 'MM/DD/YYYY hh24:mi:ss.ff' format and to use TO_TIMESTAMP instead of TO_DATE cause dates don't hold millis in oracle.

For this scenario HTTP 404 is response code for the response from the REST API Like 400, 401, 404 , 422 unprocessable entity

use the Exception handling to check the full exception message.

try{
  // call the rest api
} catch(RestClientException e) {
     //process exception
     if(e instanceof HttpStatusCodeException){
        String responseText=((HttpStatusCodeException)e).getResponseBodyAsString();
         //now you have the response, construct json from it, and extract the errors
         System.out.println("Exception :" +responseText);
     }

}

This exception block give you the proper message thrown by the REST API
