This is how you should setup Eclipse Debugger for remote debugging:

Eclipse Settings:

1.Click the Run Button
2.Select the Debug Configurations
3.Select the “Remote Java Application”
4.New Configuration

• Name : GatewayPortalProject
• Project : GatewayPortal-portlet
• Connection Type: Socket Attach
• Connection Properties: i) localhost ii) 8787

For JBoss:

1.Change the /path/toJboss/jboss-eap-6.1/bin/standalone.conf in your vm as follows: Uncomment the following line by removing the #:

JAVA_OPTS="$JAVA_OPTS -agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n"

For Tomcat :

In catalina.bat file :

Step 1:

CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"

Step 2:

JPDA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"

Step 3: Run Tomcat from command prompt like below:

catalina.sh jpda start

Then you need to set breakpoints in the Java classes you desire to debug.

I encountered some weird behaviour that did not reflect the actual code base so after some time trying several solutions, my problem was solved by manually deleting everything under /var/cache/tomcat8/

We put the default values in the database through migrations (by specifying the :default option on each column definition) and let Active Record use these values to set the default for each attribute.

IMHO, this approach is aligned with the principles of AR : convention over configuration, DRY, the table definition drives the model, not the other way around.

Note that the defaults are still in the application (Ruby) code, though not in the model but in the migration(s).

If you are ok with using Lodash, you can do the thing you wanted in one line using _.set():

_.set(object, path, value) Sets the property value of path on object. If a portion of path does not exist it’s created.

https://lodash.com/docs#set

So your example would simply be: _.set($scope, the_string, something);

First of all, like Steven Rumbalski said, "PEP8 doesn't address this question", so it is a matter of personal preference.

I would use a similar but not identical format as your format 3. Here is mine, and why.

my_dictionary = { # Don't think dict(...) notation has more readability
    "key1": 1, # Indent by one press of TAB (i.e. 4 spaces)
    "key2": 2, # Same indentation scale as above
    "key3": 3, # Keep this final comma, so that future addition won't show up as 2-lines change in code diff
    } # My favorite: SAME indentation AS ABOVE, to emphasize this bracket is still part of the above code block!
the_next_line_of_code() # Otherwise the previous line would look like the begin of this part of code

bad_example = {
               "foo": "bar", # Don't do this. Unnecessary indentation wastes screen space
               "hello": "world" # Don't do this. Omitting the comma is not good.
} # You see? This line visually "joins" the next line when in a glance
the_next_line_of_code()

btw_this_is_a_function_with_long_name_or_with_lots_of_parameters(
    foo='hello world',  # So I put one parameter per line
    bar=123,  # And yeah, this extra comma here is harmless too;
              # I bet not many people knew/tried this.
              # Oh did I just show you how to write
              # multiple-line inline comment here?
              # Basically, same indentation forms a natural paragraph.
    ) # Indentation here. Same idea as the long dict case.
the_next_line_of_code()

# By the way, now you see how I prefer inline comment to document the very line.
# I think this inline style is more compact.
# Otherwise you will need extra blank line to split the comment and its code from others.

some_normal_code()

# hi this function is blah blah
some_code_need_extra_explanation()

some_normal_code()

The solution given didn't work for me on the desktop, it just showed both divs, although the mobile only showed the mobile div. So I did a little search and found the min-width option. I updated my code to the following and it works fine now :)

CSS:

    @media all and (min-width: 480px) {
    .deskContent {display:block;}
    .phoneContent {display:none;}
}

@media all and (max-width: 479px) {
    .deskContent {display:none;}
    .phoneContent {display:block;}
}

HTML:

<div class="deskContent">Content for desktop</div>
<div class="phoneContent">Content for mobile</div>

Here you can download visual studio 2017 initial installer:

https://docs.microsoft.com/en-us/visualstudio/install/create-an-offline-installation-of-visual-studio?view=vs-2017

Run it and after few minutes it will ask what components do you want to install and in the right bottom there will be two option
"Install while downloading"
"Download all, then install"

Select any option and click install.

You can use CreateTextFile or OpenTextFile method, both have an attribute "unicode" usefull for encoding settings.

object.CreateTextFile(filename[, overwrite[, unicode]])        
object.OpenTextFile(filename[, iomode[, create[, format]]])

Example: Overwrite:

CreateTextFile:
 fileName = "filename"
 Set fso = CreateObject("Scripting.FileSystemObject")
 Set out = fso.CreateTextFile(fileName, True, True)
 out.WriteLine ("Hello world!")
 ...
 out.close

Example: Append:

 OpenTextFile Set fso = CreateObject("Scripting.FileSystemObject")
 Set out = fso.OpenTextFile("filename", ForAppending, True, 1)
 out.Write "Hello world!"
 ...
 out.Close

See more on MSDN docs

Here's the trick:

First, set your Vi(m) session to allow pattern matching with special characters (i.e.: newline). It's probably worth putting this line in your .vimrc or .exrc file:

:set magic

Next, do:

:s/,/,^M/g

To get the ^M character, type Ctrl + V and hit Enter. Under Windows, do Ctrl + Q, Enter. The only way I can remember these is by remembering how little sense they make:

A: What would be the worst control-character to use to represent a newline?

B: Either q (because it usually means "Quit") or v because it would be so easy to type Ctrl + C by mistake and kill the editor.

A: Make it so.

Union type is in my mind best option in this case:

interface Employee{
   id: number;
   name: string;
   salary: number | null;
}

// Both cases are valid
let employe1: Employee = { id: 1, name: 'John', salary: 100 };
let employe2: Employee = { id: 1, name: 'John', salary: null };

EDIT : For this to work as expected, you should enable the strictNullChecks in tsconfig.

For rounding, you should probably use the C functions defined in math.h.

int roundedX = round(x);

Hold down Option and double click on round in Xcode and it will show you the man page with various functions for rounding different types.

Reading the remark of Kleopatra (her 2nd time she suggested to have a look at javax.swing.JXTable, and now I Am sorry I didn't have a look the first time :) ) I suggest you follow the link

I had this solution for the same problem: (but I suggest you follow the link above) On resize the table, scale the table column widths to the current table total width. to do this I use a global array of ints for the (relative) column widths):

private int[] columnWidths=null;

I use this function to set the table column widths:

public void setColumnWidths(int[] widths){
    int nrCols=table.getModel().getColumnCount();
    if(nrCols==0||widths==null){
        return;
    }
    this.columnWidths=widths.clone();

    //current width of the table:
    int totalWidth=table.getWidth();
    
    int totalWidthRequested=0;
    int nrRequestedWidths=columnWidths.length;
    int defaultWidth=(int)Math.floor((double)totalWidth/(double)nrCols);

    for(int col=0;col<nrCols;col++){
        int width = 0;
        if(columnWidths.length>col){
            width=columnWidths[col];
        }
        totalWidthRequested+=width;
    }
    //Note: for the not defined columns: use the defaultWidth
    if(nrRequestedWidths<nrCols){
        log.fine("Setting column widths: nr of columns do not match column widths requested");
        totalWidthRequested+=((nrCols-nrRequestedWidths)*defaultWidth);
    }
    //calculate the scale for the column width
    double factor=(double)totalWidth/(double)totalWidthRequested;

    for(int col=0;col<nrCols;col++){
        int width = defaultWidth;
        if(columnWidths.length>col){
            //scale the requested width to the current table width
            width=(int)Math.floor(factor*(double)columnWidths[col]);
        }
        table.getColumnModel().getColumn(col).setPreferredWidth(width);
        table.getColumnModel().getColumn(col).setWidth(width);
    }
    
}

When setting the data I call:

    setColumnWidths(this.columnWidths);

and on changing I call the ComponentListener set to the parent of the table (in my case the JScrollPane that is the container of my table):

public void componentResized(ComponentEvent componentEvent) {
    this.setColumnWidths(this.columnWidths);
}

note that the JTable table is also global:

private JTable table;

And here I set the listener:

    scrollPane=new JScrollPane(table);
    scrollPane.addComponentListener(this);

You need to deal with the optional Rank parameter of UBound.

Dim arr(1 To 4, 1 To 3) As Variant
Debug.Print UBound(arr, 1)  '? returns 4
Debug.Print UBound(arr, 2)  '? returns 3

More at: UBound Function (Visual Basic)

In my case I was getting this error because the option (HttpActivation) was not enabled.

How will the browser know when to run the code inside script tag? So, to make the code run after the window is loaded completely,

window.onload = doStuff;

function doStuff() {
    var e = document.getElementById("db_info");
    e.innerHTML='Found you';
}

The other alternative is to keep your <script...</script> just before the closing </body> tag.

A basic implementation would be something like this:

public class Test {
    public static void main(String[] args) {
        int[] input = new int[] { 0x1234, 0x5678, 0x9abc };
        byte[] output = new byte[input.length * 2];

        for (int i = 0, j = 0; i < input.length; i++, j+=2) {
            output[j] = (byte)(input[i] & 0xff);
            output[j+1] = (byte)((input[i] >> 8) & 0xff);
        }

        for (int i = 0; i < output.length; i++)
            System.out.format("%02x\n",output[i]);
    }
}

In order to understand things you can read this WP article: http://en.wikipedia.org/wiki/Endianness

The above source code will output 34 12 78 56 bc 9a. The first 2 bytes (34 12) represent the first integer, etc. The above source code encodes integers in little endian format.

I suspect ^ doesn't work the way you think it does outside of a character class.

What you're telling it to do is replace everything that isn't an alphanumeric with an empty string, OR any leading space. I think what you mean to say is that spaces are ok to not replace - try moving the \s into the [] class.

This problem has bothered me for 15 years, and all the solutions supplied weren't satisfactory for me. How do you create a dynamic multidimensional array contiguously in memory? Today I finally found the answer. Using the following code, you can do just that:

#include <iostream>

int main(int argc, char** argv)
{
    if (argc != 3)
    {
        std::cerr << "You have to specify the two array dimensions" << std::endl;
        return -1;
    }

    int sizeX, sizeY;

    sizeX = std::stoi(argv[1]);
    sizeY = std::stoi(argv[2]);

    if (sizeX <= 0)
    {
        std::cerr << "Invalid dimension x" << std::endl;
        return -1;
    }
    if (sizeY <= 0)
    {
        std::cerr << "Invalid dimension y" << std::endl;
        return -1;
    }

    /******** Create a two dimensional dynamic array in continuous memory ******
     *
     * - Define the pointer holding the array
     * - Allocate memory for the array (linear)
     * - Allocate memory for the pointers inside the array
     * - Assign the pointers inside the array the corresponding addresses
     *   in the linear array
     **************************************************************************/

    // The resulting array
    unsigned int** array2d;

    // Linear memory allocation
    unsigned int* temp = new unsigned int[sizeX * sizeY];

    // These are the important steps:
    // Allocate the pointers inside the array,
    // which will be used to index the linear memory
    array2d = new unsigned int*[sizeY];

    // Let the pointers inside the array point to the correct memory addresses
    for (int i = 0; i < sizeY; ++i)
    {
        array2d[i] = (temp + i * sizeX);
    }



    // Fill the array with ascending numbers
    for (int y = 0; y < sizeY; ++y)
    {
        for (int x = 0; x < sizeX; ++x)
        {
            array2d[y][x] = x + y * sizeX;
        }
    }



    // Code for testing
    // Print the addresses
    for (int y = 0; y < sizeY; ++y)
    {
        for (int x = 0; x < sizeX; ++x)
        {
            std::cout << std::hex << &(array2d[y][x]) << ' ';
        }
    }
    std::cout << "\n\n";

    // Print the array
    for (int y = 0; y < sizeY; ++y)
    {
        std::cout << std::hex << &(array2d[y][0]) << std::dec;
        std::cout << ": ";
        for (int x = 0; x < sizeX; ++x)
        {
            std::cout << array2d[y][x] << ' ';
        }
        std::cout << std::endl;
    }



    // Free memory
    delete[] array2d[0];
    delete[] array2d;
    array2d = nullptr;

    return 0;
}

When you invoke the program with the values sizeX=20 and sizeY=15, the output will be the following:

As you can see, the multidimensional array lies contiguously in memory, and no two memory addresses are overlapping. Even the routine for freeing the array is simpler than the standard way of dynamically allocating memory for every single column (or row, depending on how you view the array). Since the array basically consists of two linear arrays, only these two have to be (and can be) freed.

This method can be extended for more than two dimensions with the same concept. I won't do it here, but when you get the idea behind it, it is a simple task.

I hope this code will help you as much as it helped me.

Regarding your updated question about the missing cygwin1.dll.

From the Cygwin terminal check,

ls /usr/bin/cygwin1.dll

If it is not present (I doubt that), your installation is not properly done.

Then, check your path with,

echo $PATH

This will give : separated list of paths. It MUST contain /usr/bin. If you find that missing add it with,

export PATH=/usr/bin:$PATH

Finally,

• I hope you are using Cygwin from the cygwin terminal (the little green+black icon installed with Cygwin), or MinTTY (if you installed that).
• And, you have not moved the compiled EXE to a different machine which does not have Cygwin installed (if you do that, you will need to carry the cygwin1.dll to that machine -- keep it in the same folder as the compiled EXE).

"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur. (From other SO answer)

So you can't do anything about it, it is the issue of the server.

But you could use try .. except block to handle that exception:

from socket import error as SocketError
import errno

try:
    response = urllib2.urlopen(request).read()
except SocketError as e:
    if e.errno != errno.ECONNRESET:
        raise # Not error we are looking for
    pass # Handle error here.

For me it only started working after I rebooted device (Motorola-Nexus-6).

(I also tried to clean, disable "instant run", reopen Android Studio, verified installed applications to be sure there are no clashes, disable and reenable Debug mode in phone, reconnect USB cable)

Check to see if the key-value pair is actually showing up in the request:

In Chrome, found somewhere like: F12: Developer Tools > Network Tab > Whatever request you have sent > "view source" under Response Headers

Depending on your testing workflow, if whatever pair you added isn't there, you may just need to clear your browser cache. To verify that your browser is using your most up-to-date code, you can check the page's sources, in Chrome this is found somewhere like: F12: Developer Tools > Sources Tab > YourJavascriptSrc.js and check your code.

But as other answers have said:

xhttp.setRequestHeader(key, value);

should add a key-value pair to your request header, just make sure to place it after your open() and before your send()

Not Found Exceptions

Sometimes you may wish to throw an exception if a model is not found. This is particularly useful in routes or controllers. The findOrFail and firstOrFail methods will retrieve the first result of the query. However, if no result is found, a Illuminate\Database\Eloquent\ModelNotFoundException will be thrown:

$model = App\Flight::findOrFail(1);

$model = App\Flight::where('legs', '>', 100)->firstOrFail();

If the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these methods:

Route::get('/api/flights/{id}', function ($id) {
    return App\Flight::findOrFail($id);
});

i resolved by doing below 2 easy steps :

step 1: git reset Head step 2: git add .

Set the ValueMember/DisplayMember properties to the name of the properties of your Language objects.

class Language
{
    string text;
    string value;

    public string Text
    {
        get 
        {
            return text;
        }
    }

    public string Value
    {
        get
        {
            return value;
        }
    }

    public Language(string text, string value)
    {
        this.text = text;
        this.value = value;
    }
}

...

combo.DisplayMember= "Text";
combo.ValueMember = "Value";
combo.Items.Add(new Language("English", "en"));

It accepts only a string value of "true" to represent boolean true. Best what you can do is

boolean uses_votes = "1".equals(o.get("uses_votes"));

Or if the Map actually represents an "entitiy", I think a Javabean is way much better. Or if it represents configuration settings, you may want to take a look into Apache Commons Configuration.

In addition to the accepted answer, it is useful to know the following ...

Each of those functions should have manual pages associated with them.

If you run man -k syslog (a keyword search of man pages) you will get a list of man pages that refer to, or are about syslog

$ man -k syslog
logger (1)           - a shell command interface to the syslog(3) system l...
rsyslog.conf (5)     - rsyslogd(8) configuration file
rsyslogd (8)         - reliable and extended syslogd
syslog (2)           - read and/or clear kernel message ring buffer; set c...
syslog (3)           - send messages to the system logger
vsyslog (3)          - send messages to the system logger

You need to understand the manual sections in order to delve further.

Here's an excerpt from the man page for man, that explains man page sections :

The table below shows the section numbers of the manual followed  by
the types of pages they contain.

   1   Executable programs or shell commands
   2   System calls (functions provided by the kernel)
   3   Library calls (functions within program libraries)
   4   Special files (usually found in /dev)
   5   File formats and conventions eg /etc/passwd
   6   Games
   7   Miscellaneous  (including  macro  packages and conven-
       tions), e.g. man(7), groff(7)
   8   System administration commands (usually only for root)
   9   Kernel routines [Non standard]

To read the above run

$man man 

So, if you run man 3 syslog you get a full manual page for the syslog function that you called in your code.

SYSLOG(3)                Linux Programmer's Manual                SYSLOG(3)

NAME
   closelog,  openlog,  syslog,  vsyslog  - send messages to the system
   logger

SYNOPSIS
   #include <syslog.h>

   void openlog(const char *ident, int option, int facility);
   void syslog(int priority, const char *format, ...);
   void closelog(void);

   #include <stdarg.h>

   void vsyslog(int priority, const char *format, va_list ap);

Not a direct answer but hopefully you will find this useful.

Code & detects ctrl+z

document.onkeyup = function(e) {
  if(e.ctrlKey && e.keyCode == 90) {
    // ctrl+z pressed
  }
}

I was able to find a definitive answer in JavaScript: The Definitive Guide, 6th Edition by O'Reilly, p. 391:

This solution works even in Quirks mode, while ryanve and ScottEvernden's current solution do not.

function getViewportSize(w) {

    // Use the specified window or the current window if no argument
    w = w || window;

    // This works for all browsers except IE8 and before
    if (w.innerWidth != null) return { w: w.innerWidth, h: w.innerHeight };

    // For IE (or any browser) in Standards mode
    var d = w.document;
    if (document.compatMode == "CSS1Compat")
        return { w: d.documentElement.clientWidth,
           h: d.documentElement.clientHeight };

    // For browsers in Quirks mode
    return { w: d.body.clientWidth, h: d.body.clientHeight };

}

except for the fact that I wonder why the line if (document.compatMode == "CSS1Compat") is not if (d.compatMode == "CSS1Compat"), everything looks good.

This doesn't seem to be any "easy" support for changing test directory.
However, maybe you should take a look at this issue, relative to your question.

Also this is an example of how to print List of List using advanced for loop:

public static void main(String[] args){
        int[] a={1,3, 7, 8, 3, 9, 2, 4, 10};
        List<List<Integer>> triplets;
        triplets=sumOfThreeNaive(a, 13);
        for (List<Integer> list : triplets){
            for (int triplet: list){
                System.out.print(triplet+" ");
            }
            System.out.println();
        }
    }

None of these answers solved my problem, which was that the items weren't the same width in my makeshift flexbox table when it was shrunk to a width too small.

The solution for me was simply to put overflow: hidden; on the flex-grow: 1; cells.

ES6

const [first] = Object.keys(obj)

another solution will be to grab the text inside the title tag & then use .html() method of jQuery to construct the content of the tooltip.

$(function() {
  $(document).tooltip({
    position: {
      using: function(position, feedback) {
        $(this).css(position);
        var txt = $(this).text();
        $(this).html(txt);
        $("<div>")
          .addClass("arrow")
          .addClass(feedback.vertical)
          .addClass(feedback.horizontal)
          .appendTo(this);
      }
    }
  });
});

I hope it also useful

window.addEventListener("load", function()

    window.addEventListener("orientationchange", hideAddressBar);

According to my research there is no way to do this exactly the way you want. You can manually re-create the table and copy the data, or SSMS can (and will) do this for you (when you drag and drop a column to a different order, it does this). In fact it souldn't matter what order the columns are... As an alternative solution you can select the data you want in the order you desired. For example, instead of using asterisk (*) in select, specify the column names in some order... Lets say MyTable has col1, col2, col3, colNew columns.

Instead of:

SELECT * FROM MyTable

You can use:

SELECT col1, colNew, col2, col3 FROM MyTable

Set the second function parameter to true if you require an associative array

Some versions of php require a 2nd paramter of true if you require an associative array

$json  = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$array = json_decode( $json, true );

Here is the proper solution. You should use jquery datepicker everywhere

  <script>
  $( function() {
    $( ".simple_date" ).datepicker();
  } );
  </script>

Assuming you have python 2.7 64bit on your computer and have downloaded numpy from here, follow the steps below (changing numpy-1.9.2+mkl-cp27-none-win_amd64.whl as appropriate).

1. Download (by right click and "save target") get-pip to local drive.
   
   

2. At the command prompt, navigate to the directory containing get-pip.py and run
   
   python get-pip.py
   
   which creates files in C:\Python27\Scripts, including pip2, pip2.7 and pip.
   
   

3. Copy the downloaded numpy-1.9.2+mkl-cp27-none-win_amd64.whl into the above directory (C:\Python27\Scripts)
   
   

4. Still at the command prompt, navigate to the above directory and run:
   
   pip2.7.exe install "numpy-1.9.2+mkl-cp27-none-win_amd64.whl"

If you have desired permissions saved to string then do

s = '660'
os.chmod(file_path, int(s, base=8))

The data containing the date column can be read by using the below code:

data = pd.csv(file_path,parse_dates=[date_column])

Once the data is read by using the above line of code, the column containing the information about the date can be accessed using pd.date_time() like:

pd.date_time(data[date_column], format = '%d/%m/%y')

to change the format of date as per the requirement.

You can use DatePipe for formatting Date in Angular.

In ts if you want to format date then you can inject DatePipe as Service in constructor like this

import { DatePipe } from '@angular/common';

@Component({
    templateUrl: './name.component.html',
    styleUrls: ['./name.component.scss'],
    providers: [DatePipe]
})

myDate = new Date();
constructor(private datePipe: DatePipe){
    this.myDate = this.datePipe.transform(this.myDate, 'yyyy-MM-dd');
}

And if you want to format in html file, 'Shortdate' will return date of type MM/DD/YY

{{myDate | date: 'shortDate' }}

As of Angular 6, this also works,

import {formatDate} from '@angular/common';

formatDate(new Date(), 'yyyy/MM/dd', 'en');

Just wanted to contribute my version, using regex:

private static final String UNICODE_REGEX = "\\\\u([0-9a-f]{4})";
private static final Pattern UNICODE_PATTERN = Pattern.compile(UNICODE_REGEX);
...
String message = "\u0048\u0065\u006C\u006C\u006F World";
Matcher matcher = UNICODE_PATTERN.matcher(message);
StringBuffer decodedMessage = new StringBuffer();
while (matcher.find()) {
  matcher.appendReplacement(
      decodedMessage, String.valueOf((char) Integer.parseInt(matcher.group(1), 16)));
}
matcher.appendTail(decodedMessage);
System.out.println(decodedMessage.toString());

The backslash operator is not reliable. Try pasting this function in your browser console:

function printString (){
  const s = "someLongLineOfText\
  ThatShouldNotBeBroken";
  console.log(s);
}

and then run it. Because of the conventional (and correct) indentation within the function, two extra spaces will be included, resulting in someLongLineOfText ThatShouldNotBeBroken.

Even using backticks will not help in this case. Always use the concatenation "+" operator to prevent this type of issue.

You need to set the height of every parent element of the one you want the height defined.

Without resorting gridspec entirely, the following might also be used to remove the gaps by setting wspace and hspace to zero:

import matplotlib.pyplot as plt

plt.clf()
f, axarr = plt.subplots(4, 4, gridspec_kw = {'wspace':0, 'hspace':0})

for i, ax in enumerate(f.axes):
    ax.grid('on', linestyle='--')
    ax.set_xticklabels([])
    ax.set_yticklabels([])

plt.show()
plt.close()

I recommend you to use JSON.NET. it is an open source library to serialize and deserialize your c# objects into json and Json objects into .net objects ...

Serialization Example:

Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };

string json = JsonConvert.SerializeObject(product);
//{
//  "Name": "Apple",
//  "Expiry": new Date(1230422400000),
//  "Price": 3.99,
//  "Sizes": [
//    "Small",
//    "Medium",
//    "Large"
//  ]
//}

Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);

Performance Comparison To Other JSON serializiation Techniques

The correct way to do this is:

String[] stockArr = stock_list.toArray(new String[stock_list.size()]);

I'd like to add to the other great answers here and explain how you could have used the Javadocs to answer your question.

The Javadoc for toArray() (no arguments) is here. As you can see, this method returns an Object[] and not String[] which is an array of the runtime type of your list:

public Object[] toArray()

Returns an array containing all of the elements in this collection. If the collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. The returned array will be "safe" in that no references to it are maintained by the collection. (In other words, this method must allocate a new array even if the collection is backed by an Array). The caller is thus free to modify the returned array.

Right below that method, though, is the Javadoc for toArray(T[] a). As you can see, this method returns a T[] where T is the type of the array you pass in. At first this seems like what you're looking for, but it's unclear exactly why you're passing in an array (are you adding to it, using it for just the type, etc). The documentation makes it clear that the purpose of the passed array is essentially to define the type of array to return (which is exactly your use case):

public <T> T[] toArray(T[] a)

Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array. If the collection fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this collection. If the collection fits in the specified array with room to spare (i.e., the array has more elements than the collection), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the collection only if the caller knows that the collection does not contain any null elements.)

If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

This implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). Then, it iterates over the collection, storing each object reference in the next consecutive element of the array, starting with element 0. If the array is larger than the collection, a null is stored in the first location after the end of the collection.

Of course, an understanding of generics (as described in the other answers) is required to really understand the difference between these two methods. Nevertheless, if you first go to the Javadocs, you will usually find your answer and then see for yourself what else you need to learn (if you really do).

Also note that reading the Javadocs here helps you to understand what the structure of the array you pass in should be. Though it may not really practically matter, you should not pass in an empty array like this:

String [] stockArr = stockList.toArray(new String[0]);  

Because, from the doc, this implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). There's no need for the extra overhead in creating a new array when you could easily pass in the size.

As is usually the case, the Javadocs provide you with a wealth of information and direction.

Hey wait a minute, what's reflection?

I'd like to share my experience of using Ant in building projects, *.properties files should be copied explicitly. This is because Ant will not compile *.properties files into the build working directory by default (javac just ignore *.properties). For example:

<target name="compile" depends="init">
    <javac destdir="${dst}" srcdir="${src}" debug="on" encoding="utf-8" includeantruntime="false">
        <include name="com/example/**" />
        <classpath refid="libs" />
    </javac>
    <copy todir="${dst}">
        <fileset dir="${src}" includes="**/*.properties" />
    </copy>
</target>

<target name="jars" depends="compile">
    <jar jarfile="${app_jar}" basedir="${dst}" includes="com/example/**/*.*" />
</target>

Please notice that 'copy' section under the 'compile' target, it will replicate *.properties files into the build working directory. Without the 'copy' section the jar file will not contain the properties files, then you may encounter the java.util.MissingResourceException.

Might be lately posted but hopefully this will help someone to see primary key list in sql server by using this t-sql query:

SELECT  schema_name(t.schema_id) AS [schema_name], t.name AS TableName,        
    COL_NAME(ic.OBJECT_ID,ic.column_id) AS PrimaryKeyColumnName,
    i.name AS PrimaryKeyConstraintName
FROM    sys.tables t 
INNER JOIN sys.indexes AS i  on t.object_id=i.object_id 
INNER JOIN  sys.index_columns AS ic ON  i.OBJECT_ID = ic.OBJECT_ID
                            AND i.index_id = ic.index_id 
WHERE OBJECT_NAME(ic.OBJECT_ID) = 'YourTableNameHere'

You can see the list of all foreign keys by using this query if you may want:

SELECT
f.name as ForeignKeyConstraintName
,OBJECT_NAME(f.parent_object_id) AS ReferencingTableName
,COL_NAME(fc.parent_object_id, fc.parent_column_id) AS ReferencingColumnName
,OBJECT_NAME (f.referenced_object_id) AS ReferencedTableName
,COL_NAME(fc.referenced_object_id, fc.referenced_column_id) AS 
 ReferencedColumnName  ,delete_referential_action_desc AS 
DeleteReferentialActionDesc ,update_referential_action_desc AS 
UpdateReferentialActionDesc
FROM sys.foreign_keys AS f
INNER JOIN sys.foreign_key_columns AS fc
ON f.object_id = fc.constraint_object_id
 --WHERE OBJECT_NAME(f.parent_object_id) = 'YourTableNameHere' 
 --If you want to know referecing table details 
 WHERE OBJECT_NAME(f.referenced_object_id) = 'YourTableNameHere' 
 --If you want to know refereced table details 
ORDER BY f.name

Yes you should change the name of your function. Javascript has reserved methods and onclick = >>>> click() <<<< is one of them so just rename it, add an 's' to the end of it or something. strong text`

if(a<b && a<c){

In the newest versions (from the 3.5.1315.0 beta), you can use the MajorUpgrade element instead of using your own.

For example, we use this code to do automatic upgrades. It prevents downgrades, giving a localised error message, and also prevents upgrading an already existing identical version (i.e. only lower versions are upgraded):

<MajorUpgrade
    AllowDowngrades="no" DowngradeErrorMessage="!(loc.NewerVersionInstalled)"
    AllowSameVersionUpgrades="no"
    />

Verify that you have the latest version of Node installed (or, at least 13.2.0+). Then do one of the following, as described in the documentation:

Option 1

In the nearest parent package.json file, add the top-level "type" field with a value of "module". This will ensure that all .js and .mjs files are interpreted as ES modules. You can interpret individual files as CommonJS by using the .cjs extension.

// package.json
{
  "type": "module"
}

Option 2

Explicitly name files with the .mjs extension. All other files, such as .js will be interpreted as CommonJS, which is the default if type is not defined in package.json.

With Java 8, the new java.time package should be used.

mail() returns TRUE if the mail was successfully accepted for delivery, FALSE otherwise.

It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.

If you need to suppress warnings, you can use:

if (!@mail(...))

Be careful though about using the @ operator without appropriate checks as to whether something succeed or not.

If mail() errors are not suppressible (weird, but can't test it right now), you could:

a) turn off errors temporarily:

$errLevel = error_reporting(E_ALL ^ E_NOTICE);  // suppress NOTICEs
mail(...);
error_reporting($errLevel);  // restore old error levels

b) use a different mailer, as suggested by fire and Mike.

If mail() turns out to be too flaky and inflexible, I'd look into b). Turning off errors is making debugging harder and is generally ungood.

From cron manual http://man7.org/linux/man-pages/man5/crontab.5.html:

Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9", "0-4,8-12".

So in this case it would be:

30 10,14 * * *

All the answers here suggest to use ipairs but beware, it does not work all the time.

t = {[2] = 44, [4]=77, [6]=88}

--This for loop prints the table
for key,value in next,t,nil do 
  print(key,value) 
end

--This one does not print the table
for key,value in ipairs(t) do 
  print(key,value) 
end

"This is my string with date in specified format $($theDate.ToString('u'))"

or

"This is my string with date in specified format $(Get-Date -format 'u')"

The sub-expression ($(...)) can include arbitrary expressions calls.

MSDN Documents both standard and custom DateTime format strings.

The JVM is caching Integer values. Hence the comparison with == only works for numbers between -128 and 127.

Thanks to the Stack Overflow community ... and a little research I was able to get my favorite editor, EditPad Pro, to work as the core editor with msysgit 1.7.5.GIT and TortoiseGit v1.7.3.0 over Windows XP SP3...

Following the advice above, I added the path to a Bash script for the code editor...

git config --global core.editor c:/msysgit/cmd/epp.sh

However, after several failed attempts at the above mentioned solutions ... I was finally able to get this working. Per EditPad Pro's documentation, adding the '/newinstance' flag would allow the shell to wait for the editor input...

The '/newinstance' flag was the key in my case...

#!/bin/sh
"C:/Program Files/JGsoft/EditPadPro6/EditPadPro.exe" //newinstance "$*"

I am updating a simple solution. First add an id to your segue which presents modal. Than in properties change it's presentation style to "Over Current Context". Than add this code in presenting view controller (The controller which is presenting modal).

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let Device = UIDevice.currentDevice()

    let iosVersion = NSString(string: Device.systemVersion).doubleValue

    let iOS8 = iosVersion >= 8
    let iOS7 = iosVersion >= 7 && iosVersion < 8
    if((segue.identifier == "chatTable")){

    if (iOS8){


          }
        else {

            self.navigationController?.modalPresentationStyle = UIModalPresentationStyle.CurrentContext


        }
    }
}

Make sure you change segue.identifier to your own id ;)

Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.

The trick is that the DOM Element.children attribute is not an array but an array-like collection which has length and can be indexed like an array, but it is not an array:

var children = tableFields.children;
for (var i = 0; i < children.length; i++) {
  var tableChild = children[i];
  // Do stuff
}

Incidentally, in general it is a better practice to iterate over an array using a basic for-loop instead of a for-in-loop.

Any of the following will work:

s = "true"

(s == 'true').real
1

(s == 'false').real
0

(s == 'true').conjugate()    
1

(s == '').conjugate()
0

(s == 'true').__int__()
1

(s == 'opal').__int__()    
0


def as_int(s):
    return (s == 'true').__int__()

>>>> as_int('false')
0
>>>> as_int('true')
1

Abstract classes can contain methods that are not abstract, whereas in interfaces all your methods are abstract and have to be implemented.

You should use interfaces instead when you know you will always implement those certain methods. Also you can inherit from multiple interfaces, it is java's way of dealing with multiple inheritance

If you are currently not on branch master, that's super easy:

git branch -f master 1258f0d0aae

This does exactly what you want: It points master at the given commit, and does nothing else.

If you are currently on master, you need to get into detached head state first. I'd recommend the following two command sequence:

git checkout 1258f0d0aae    #detach from master
git branch -f master HEAD   #exactly as above

#optionally reattach to master
git checkout master

Be aware, though, that any explicit manipulation of where a branch points has the potential to leave behind commits that are no longer reachable by any branches, and thus become object to garbage collection. So, think before you type git branch -f!

This method is better than the git reset --hard approach, as it does not destroy anything in the index or working directory.

REST APIs must be hypertext-driven

From Roy Fielding's blog here's a set of ways to check if you're building a HTTP API or a REST API:

API designers, please note the following rules before calling your creation a REST API:

• A REST API should not be dependent on any single communication protocol, though its successful mapping to a given protocol may be dependent on the availability of metadata, choice of methods, etc. In general, any protocol element that uses a URI for identification must allow any URI scheme to be used for the sake of that identification. [Failure here implies that identification is not separated from interaction.]
• A REST API should not contain any changes to the communication protocols aside from filling-out or fixing the details of underspecified bits of standard protocols, such as HTTP’s PATCH method or Link header field. Workarounds for broken implementations (such as those browsers stupid enough to believe that HTML defines HTTP’s method set) should be defined separately, or at least in appendices, with an expectation that the workaround will eventually be obsolete. [Failure here implies that the resource interfaces are object-specific, not generic.]
• A REST API should spend almost all of its descriptive effort in defining the media type(s) used for representing resources and driving application state, or in defining extended relation names and/or hypertext-enabled mark-up for existing standard media types. Any effort spent describing what methods to use on what URIs of interest should be entirely defined within the scope of the processing rules for a media type (and, in most cases, already defined by existing media types). [Failure here implies that out-of-band information is driving interaction instead of hypertext.]
• A REST API must not define fixed resource names or hierarchies (an obvious coupling of client and server). Servers must have the freedom to control their own namespace. Instead, allow servers to instruct clients on how to construct appropriate URIs, such as is done in HTML forms and URI templates, by defining those instructions within media types and link relations. [Failure here implies that clients are assuming a resource structure due to out-of band information, such as a domain-specific standard, which is the data-oriented equivalent to RPC’s functional coupling].
• A REST API should never have “typed” resources that are significant to the client. Specification authors may use resource types for describing server implementation behind the interface, but those types must be irrelevant and invisible to the client. The only types that are significant to a client are the current representation’s media type and standardized relation names. [ditto]
• A REST API should be entered with no prior knowledge beyond the initial URI (bookmark) and set of standardized media types that are appropriate for the intended audience (i.e., expected to be understood by any client that might use the API). From that point on, all application state transitions must be driven by client selection of server-provided choices that are present in the received representations or implied by the user’s manipulation of those representations. The transitions may be determined (or limited by) the client’s knowledge of media types and resource communication mechanisms, both of which may be improved on-the-fly (e.g., code-on-demand). [Failure here implies that out-of-band information is driving interaction instead of hypertext.]

Just to add to how to use map files. I use chrome for ubuntu and if I go to sources and click on a file, if there is a map file a message comes up telling me that I can view the original file and how to do it.

For the Angular files that I worked with today I click

Ctrl-P and a list of original files comes up in a small window.

I can then browse through the list to view the file that I would like to inspect and check where the issue might be.

// 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

I've come across this "deep object copy" function that I've found handy for duplicating objects by value. It doesn't use jQuery, but it certainly is deep.

http://www.overset.com/2007/07/11/javascript-recursive-object-copy-deep-object-copy-pass-by-value/

You can try this:

import * as _Window from "jsdom/lib/jsdom/browser/Window";

window.open = jest.fn().mockImplementationOnce(() => {
    return new _Window({ parsingMode: "html" });
});

it("correct url is called", () => {
    statementService.openStatementsReport(111);
    expect(window.open).toHaveBeenCalled();
});

Apologies in advance for this lo-tech suggestion, but another option, which finally worked for me after battling NuGet for several hours, is to re-create a new empty project, Web API in my case, and just copy the guts of your old, now-broken project into the new one. Took me about 15 minutes.

Here is a simple function which does exactly this :

#include <windows.h>
#include <string>

bool dirExists(const std::string& dirName_in)
{
  DWORD ftyp = GetFileAttributesA(dirName_in.c_str());
  if (ftyp == INVALID_FILE_ATTRIBUTES)
    return false;  //something is wrong with your path!

  if (ftyp & FILE_ATTRIBUTE_DIRECTORY)
    return true;   // this is a directory!

  return false;    // this is not a directory!
}

A little anecdote to illustrate the use of array_key_exists.

// A programmer walked through the parking lot in search of his car
// When he neared it, he reached for his pocket to grab his array of keys
$keyChain = array(
    'office-door' => unlockOffice(),
    'home-key' => unlockSmallApartment(),
    'wifes-mercedes' => unusedKeyAfterDivorce(),
    'safety-deposit-box' => uselessKeyForEmptyBox(),
    'rusto-old-car' => unlockOldBarrel(),
);

// He tried and tried but couldn't find the right key for his car
// And so he wondered if he had the right key with him.
// To determine this he used array_key_exists
if (array_key_exists('rusty-old-car', $keyChain)) {
    print('Its on the chain.');
}

For List<List<List<x>>> and so on, use

list.SelectMany(x => x.SelectMany(y => y)).ToList();

This has been posted in a comment, but it does deserves a separate reply in my opinion.

Enum serves as a type of fixed number of constants and can be used at least for two things

constant

public enum Month {
    JANUARY, FEBRUARY, ...
}

This is much better than creating a bunch of integer constants.

creating a singleton

public enum Singleton {
    INSTANCE

   // init
};

You can do quite interesting things with enums, look at here

Also look at the official documentation

there is also git stash - which "stashes" your local changes and can be reapplied at a later time or dropped if is no longer required

more info on stashing

One of the way is Using below sql queries

--Size of All Table Space

--1. Used Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "USED SPACE(IN GB)" FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME
--2. Free Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "FREE SPACE(IN GB)" FROM   USER_FREE_SPACE GROUP BY TABLESPACE_NAME

--3. Both Free & Used
SELECT USED.TABLESPACE_NAME, USED.USED_BYTES AS "USED SPACE(IN GB)",  FREE.FREE_BYTES AS "FREE SPACE(IN GB)"
FROM
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS USED_BYTES FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME) USED
INNER JOIN
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS FREE_BYTES FROM  USER_FREE_SPACE GROUP BY TABLESPACE_NAME) FREE
ON (USED.TABLESPACE_NAME = FREE.TABLESPACE_NAME);

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

You can also use array_reduce() if you prefer a more functional approach

For instance:

$userNames = array_reduce($users, function ($carry, $user) {
    array_push($carry, $user['name']);
    return $carry;
}, []);

Or if you like to be fancy,

$userNames = [];
array_map(function ($user) use (&$userNames){
    $userNames[]=$user['name'];
}, $users);

This and all the methods above do loop behind the scenes though ;)

This is my working solution:

vbFILEOPEN = "your_utf8_file.csv"
Workbooks.OpenText Filename:=vbFILEOPEN, DataType:=xlDelimited, Semicolon:=True, Local:=True, Origin:=65001

The key is Origin:=65001

Now in Python >= 3.3 you can just call the timestamp() method to get the timestamp as a float.

import datetime
current_time = datetime.datetime.now(datetime.timezone.utc)
unix_timestamp = current_time.timestamp() # works if Python >= 3.3

unix_timestamp_plus_5_min = unix_timestamp + (5 * 60)  # 5 min * 60 seconds

aggregate(speed~dive,data=df,FUN=mean)
   dive     speed
1 dive1 0.7059729
2 dive2 0.5473777

Input doesn't support multiple lines. You need to use a textarea to achieve that feature.

<textarea name="Text1"></textarea>

Remeber that the <textarea> have the value inside the tag, not in attribute:

<textarea>INITIAL VALUE GOES HERE</textarea>

It cannot be self closed as: <textarea/>

For more information, take a look to this.

Why does it give me that error?

Because your first parameter you pass to the loop function is None but your function is expecting an callable object, which None object isn't.

Therefore you have to pass the callable-object which is in your case the hi function object.

def hi():     
  print 'hi'

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)

1 day = 86400000 milliseconds.

DecodeTime(milliseconds/86400000,hr,min,sec,msec)

Ups! I was thinking in delphi, there must be something similar in all languages.

--- UPDATE 3 --- (does not conflict with UPDATE 2)

Considering the case that windows users prefer working on CRLF and linux/mac users prefer working on LF on text files. Providing the answer from the perspective of a repository maintainer:

For me the best strategy(less problems to solve) is: keep all text files with LF inside git repo even if you are working on a windows-only project. Then give the freedom to clients to work on the line-ending style of their preference, provided that they pick a core.autocrlf property value that will respect your strategy (LF on repo) while staging files for commit.

Staging is what many people confuse when trying to understand how newline strategies work. It is essential to undestand the following points before picking the correct value for core.autocrlf property:

• Adding a text file for commit (staging it) is like copying the file to another place inside .git/ sub-directory with converted line-endings (depending on core.autocrlf value on your client config). All this is done locally.
• setting core.autocrlf is like providing an answer to the question (exact same question on all OS):
  • "Should git-client a. convert LF-to-CRLF when checking-out (pulling) the repo changes from the remote or b. convert CRLF-to-LF when adding a file for commit?" and the possible answers (values) are:
  • false: "do none of the above",
  • input: "do only b"
  • true: "do a and and b"
  • note that there is NO "do only a"

Fortunately

• git client defaults (windows: core.autocrlf: true, linux/mac: core.autocrlf: false) will be compatible with LF-only-repo strategy.
  Meaning: windows clients will by default convert to CRLF when checking-out the repository and convert to LF when adding for commit. And linux clients will by default not do any conversions. This theoretically keeps your repo lf-only.

Unfortunately:

• There might be GUI clients that do not respect the git core.autocrlf value
• There might be people that don't use a value to respect your lf-repo strategy. E.g. they use core.autocrlf=false and add a file with CRLF for commit.

To detect ASAP non-lf text files committed by the above clients you can follow what is described on --- update 2 ---: (git grep -I --files-with-matches --perl-regexp '\r' HEAD, on a client compiled using: --with-libpcre flag)

And here is the catch:. I as a repo maintainer keep a git.autocrlf=input so that I can fix any wrongly committed files just by adding them again for commit. And I provide a commit text: "Fixing wrongly committed files".

As far as .gitattributes is concearned. I do not count on it, because there are more ui clients that do not understand it. I only use it to provide hints for text and binary files, and maybe flag some exceptional files that should everywhere keep the same line-endings:

*.java          text !eol # Don't do auto-detection. Treat as text (don't set any eol rule. use client's)
*.jpg           -text     # Don't do auto-detection. Treat as binary
*.sh            text eol=lf # Don't do auto-detection. Treat as text. Checkout and add with eol=lf
*.bat           text eol=crlf # Treat as text. Checkout and add with eol=crlf

Question: But why are we interested at all in newline handling strategy?

Answer: To avoid a single letter change commit, appear as a 5000-line change, just because the client that performed the change auto-converted the full file from crlf to lf (or the opposite) before adding it for commit. This can be rather painful when there is a conflict resolution involved. Or it could in some cases be the cause of unreasonable conflicts.

--- UPDATE 2 ---

The dafaults of git client will work in most cases. Even if you only have windows only clients, linux only clients or both. These are:

• windows: core.autocrlf=true means convert lines to CRLF on checkout and convert lines to LF when adding files.
• linux: core.autocrlf=input means don't convert lines on checkout (no need to since files are expected to be committed with LF) and convert lines to LF (if needed) when adding files. (-- update3 -- : Seems that this is false by default, but again it is fine)

The property can be set in different scopes. I would suggest explicitly setting in the --global scope, to avoid some IDE issues described at the end.

git config core.autocrlf
git config --global core.autocrlf
git config --system core.autocrlf
git config --local core.autocrlf
git config --show-origin core.autocrlf

Also I would strongly discourage using on windows git config --global core.autocrlf false (in case you have windows only clients) in contrast to what is proposed to git documentation. Setting to false will commit files with CRLF in the repo. But there is really no reason. You never know whether you will need to share the project with linux users. Plus it's one extra step for each client that joins the project instead of using defaults.

Now for some special cases of files (e.g. *.bat *.sh) which you want them to be checked-out with LF or with CRLF you can use .gitattributes

To sum-up for me the best practice is:

• Make sure that every non-binary file is committed with LF on git repo (default behaviour).
• Use this command to make sure that no files are committed with CRLF: git grep -I --files-with-matches --perl-regexp '\r' HEAD (Note: on windows clients works only through git-bash and on linux clients only if compiled using --with-libpcre in ./configure).
• If you find any such files by executing the above command, correct them. This in involves (at least on linux):
  • set core.autocrlf=input (--- update 3 --)
  • change the file
  • revert the change(file is still shown as changed)
  • commit it
• Use only the bare minimum .gitattributes
• Instruct the users to set the core.autocrlf described above to its default values.
• Do not count 100% on the presence of .gitattributes. git-clients of IDEs may ignore them or treat them differrently.

As said some things can be added in git attributes:

# Always checkout with LF
*.sh            text eol=lf
# Always checkout with CRLF
*.bat           text eol=crlf

I think some other safe options for .gitattributes instead of using auto-detection for binary files:

• -text (e.g for *.zip or *.jpg files: Will not be treated as text. Thus no line-ending conversions will be attempted. Diff might be possible through conversion programs)
• text !eol (e.g. for *.java,*.html: Treated as text, but eol style preference is not set. So client setting is used.)
• -text -diff -merge (e.g for *.hugefile: Not treated as text. No diff/merge possible)

--- PREVIOUS UPDATE ---

One painful example of a client that will commit files wrongly:

netbeans 8.2 (on windows), will wrongly commit all text files with CRLFs, unless you have explicitly set core.autocrlf as global. This contradicts to the standard git client behaviour, and causes lots of problems later, while updating/merging. This is what makes some files appear different (although they are not) even when you revert.
The same behaviour in netbeans happens even if you have added correct .gitattributes to your project.

Using the following command after a commit, will at least help you detect early whether your git repo has line ending issues: git grep -I --files-with-matches --perl-regexp '\r' HEAD

I have spent hours to come up with the best possible use of .gitattributes, to finally realize, that I cannot count on it.
Unfortunately, as long as JGit-based editors exist (which cannot handle .gitattributes correctly), the safe solution is to force LF everywhere even on editor-level.

I combined the efficiency of Mark's solution - so I do not have to .Clone the entire DataTable - with generics and extensibility, so I can define my own conversion function. This is what I ended up with:

/// <summary>
///     Converts a column in a DataTable to another type using a user-defined converter function.
/// </summary>
/// <param name="dt">The source table.</param>
/// <param name="columnName">The name of the column to convert.</param>
/// <param name="valueConverter">Converter function that converts existing values to the new type.</param>
/// <typeparam name="TTargetType">The target column type.</typeparam>
public static void ConvertColumnTypeTo<TTargetType>(this DataTable dt, string columnName, Func<object, TTargetType> valueConverter)
{
    var newType = typeof(TTargetType);

    DataColumn dc = new DataColumn(columnName + "_new", newType);

    // Add the new column which has the new type, and move it to the ordinal of the old column
    int ordinal = dt.Columns[columnName].Ordinal;
    dt.Columns.Add(dc);
    dc.SetOrdinal(ordinal);

    // Get and convert the values of the old column, and insert them into the new
    foreach (DataRow dr in dt.Rows)
    {
        dr[dc.ColumnName] = valueConverter(dr[columnName]);
    }

    // Remove the old column
    dt.Columns.Remove(columnName);

    // Give the new column the old column's name
    dc.ColumnName = columnName;
}

This way, usage is a lot more straightforward, while also customizable:

DataTable someDt = CreateSomeDataTable();
// Assume ColumnName is an int column which we want to convert to a string one.
someDt.ConvertColumnTypeTo<string>('ColumnName', raw => raw.ToString());

Considering there might be several img tags I would recommend re.findall:

import re

with open("sample.txt", 'r') as f_in, open('writetest.txt', 'w') as f_out:
    for line in f_in:
        for img in re.findall('<img[^>]+>', line):
            print >> f_out, "yo it's a {}".format(img)

I also found this format online, and used it. Seems to work with or without dashes. I have verified it works on my Mac (tries to call the number in FaceTime), and on my iPhone:

<!-- Cross-platform compatible (Android + iPhone) -->
<a href="tel://1-555-555-5555">+1 (555) 555-5555</a>

You need to use MM as mm stands for minutes.

There are two ways of producing month pattern.

SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy"); //outputs month in numeric way, 2013-02-01

SimpleDateFormat sdf2 = new SimpleDateFormat("dd-MMM-yyyy"); // Outputs months as follows, 2013-Feb-01

Full coding snippet:

        String startDate="01-Feb-2013"; // Input String
        SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy"); // New Pattern
        java.util.Date date = sdf1.parse(startDate); // Returns a Date format object with the pattern
        java.sql.Date sqlStartDate = new java.sql.Date(date.getTime());
        System.out.println(sqlStartDate); // Outputs : 2013-02-01

In Python3.6, the StringIO and cStringIO modules are gone, you should use io.StringIO instead.So you should do this like the first answer:

import sys
from io import StringIO

old_stdout = sys.stdout
old_stderr = sys.stderr
my_stdout = sys.stdout = StringIO()
my_stderr = sys.stderr = StringIO()

# blah blah lots of code ...

sys.stdout = self.old_stdout
sys.stderr = self.old_stderr

// if you want to see the value of redirect output, be sure the std output is turn back
print(my_stdout.getvalue())
print(my_stderr.getvalue())

my_stdout.close()
my_stderr.close()

Remove the comma

... Gender,Contact, " + ") VALUES ...
                  ^-----------------here

if you use 'Month' in to_char it right pads to 9 characters; you have to use the abbreviated 'MON', or to_char then trim and concatenate it to avoid this. See, http://www.techonthenet.com/oracle/functions/to_char.php

select trim(to_char(date_field, 'month')) || ' ' || to_char(date_field,'dd, yyyy')
  from ...

or

select to_char(date_field,'mon dd, yyyy')
  from ...  

You can also get the value of an item in the jObject like this:

JToken value;
if (json.TryGetValue(key, out value))
{
   DoSomething(value);
}

public class InitHelloWorld implements BeanPostProcessor {

   public Object postProcessBeforeInitialization(Object bean,
             String beanName) throws BeansException {
       System.out.println("BeforeInitialization : " + beanName);
       return bean;  // you can return any other object as well
   }

   public Object postProcessAfterInitialization(Object bean,
             String beanName) throws BeansException {
       System.out.println("AfterInitialization : " + beanName);
       return bean;  // you can return any other object as well
   }

}

input.Replace("\r\n", "\n").Replace("\r", "\n").Replace("\n", "\r\n")

This will work if the input contains only one type of line breaks - either CR, or LF, or CR+LF.

Its all about data which you pass; has to properly formatted string. If you are passing empty data then data: {} will work. However with multiple parameters it has to be properly formatted e.g.

var dataParam = '{' + '"data1Variable": "' + data1Value+ '", "data2Variable": "' + data2Value+ '"' +  '}';

....

data : dataParam

...

Best way to understand is have error handler with proper message parameter, so as to know the detailed errors.

If you don't want to mess with your display options and you just want to see this one particular list of columns without expanding out every dataframe you view, you could try:

df.columns.values

Quoting Conventions for Web Developers

The Short Answer

In HTML the use of single quotes (') and double quotes (") are interchangeable, there is no difference.

But consistency is recommended, therefore we must pick a syntax convention and use it regularly.

The Long Answer

Web Development often consists of many programming languages. HTML, JS, CSS, PHP, ASP, RoR, Python, ect. Because of this we have many syntax conventions for different programing languages. Often habbits from one language will follow us to other languages, even if it is not considered "proper" i.e. commenting conventions. Quoting conventions also falls into this category for me.

But I tend to use HTML tightly in conjunction with PHP. And in PHP there is a major difference between single quotes and double quotes. In PHP with double quotes "you can insert variables directly within the text of the string". (scriptingok.com) And when using single quotes "the text appears as it is". (scriptingok.com)

PHP takes longer to process double quoted strings. Since the PHP parser has to read the whole string in advance to detect any variable inside—and concatenate it—it takes longer to process than a single quoted string. (scriptingok.com)

Single quotes are easier on the server. Since PHP does not need to read the whole string in advance, the server can work faster and happier. (scriptingok.com)

Other things to consider

1. Frequency of double quotes within string. I find that I need to use double quotes (") within my strings more often than I need to use single quotes (') within strings. To reduce the number of character escapes needed I favor single quote delimiters.
2. It's easier to make a single quote. This is fairly self explanatory but to clarify, why press the SHIFT key more times then you have to.

My Convention

With this understanding of PHP I have set the convention (for myself and the rest of my company) that strings are to be represented as single quotes by default for server optimization. Double quotes are used within the string if a quotes are required such as JavaScript within an attribute, for example:

<button onClick='func("param");'>Press Me</button>

Of course if we are in PHP and want the parser to handle PHP variables within the string we should intentionally use double quotes. $a='Awesome'; $b = "Not $a";

You do not need as.vector(), but you do need correct indexing: avector <- aframe[ , "a2"]

The one other thing to be aware of is the drop=FALSE option to [:

A much simpler solution would be to download the file using Chrome. In this manner you don't have to manually click on the save button.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
    class MyProcess
    {
        public static void Main()
        {
            Process myProcess = new Process();
            myProcess.Start("chrome.exe","http://www.com/newfile.zip");
        }
    }
}

Faced the same error. In my case , what i did wrong was that i injected the service(named DataService in my case) inside the constructor within the Component but I simply forgot to import it within the component.

 constructor(private dataService:DataService ) {
    console.log("constructor called");
  }

I missed the below import code.

import { DataService } from '../../services/data.service';

Bear in mind that using WaitForSingleObject can get you into trouble in this scenario. The following is snipped from a tip on my website:

The problem arises because your application has a window but isn't pumping messages. If the spawned application invokes SendMessage with one of the broadcast targets (HWND_BROADCAST or HWND_TOPMOST), then the SendMessage won't return to the new application until all applications have handled the message - but your app can't handle the message because it isn't pumping messages.... so the new app locks up, so your wait never succeeds.... DEADLOCK.

If you have absolute control over the spawned application, then there are measures you can take, such as using SendMessageTimeout rather than SendMessage (e.g. for DDE initiations, if anybody is still using that). But there are situations which cause implicit SendMessage broadcasts over which you have no control, such as using the SetSysColors API for instance.

The only safe ways round this are:

1. split off the Wait into a separate thread, or
2. use a timeout on the Wait and use PeekMessage in your Wait loop to ensure that you pump messages, or
3. use the MsgWaitForMultipleObjects API.

It seems like you have it worked out, but for others looking for this answer, an easy way to do this is by printing to stderr. You can do that like this:

from __future__ import print_function # In python 2.7
import sys

@app.route('/button/')
def button_clicked():
    print('Hello world!', file=sys.stderr)
    return redirect('/')

Flask will display things printed to stderr in the console. For other ways of printing to stderr, see this stackoverflow post

MyClass obj = new MyClass();
ArrayList<Integer> numbers = obj.myNumbers();

It is worth noting that you can build upon Gavin Toweys answer by using multiple fields from across your query such as

SUM(table.field = 1 AND table2.field = 2)

You can also use this syntax for COUNT and I am sure other functions as well.

If you want to match the two words in either order, use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)|(Failed.*VendorEnquiry)'

If Failed always comes after VendorEnquiry on the line, just use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)'

I did so:

using System.Linq.Expressions;

namespace System.Linq
{
    public static class LinqExtensions
    {

        public static IOrderedQueryable<TSource> OrderBy<TSource>(this IQueryable<TSource> source, string field, string dir = "asc")
        {
            // parametro => expressão
            var parametro = Expression.Parameter(typeof(TSource), "r");
            var expressao = Expression.Property(parametro, field);
            var lambda = Expression.Lambda(expressao, parametro); // r => r.AlgumaCoisa
            var tipo = typeof(TSource).GetProperty(field).PropertyType;

            var nome = "OrderBy";
            if (string.Equals(dir, "desc", StringComparison.InvariantCultureIgnoreCase))
            {
                nome = "OrderByDescending";
            }
            var metodo = typeof(Queryable).GetMethods().First(m => m.Name == nome && m.GetParameters().Length == 2);
            var metodoGenerico = metodo.MakeGenericMethod(new[] { typeof(TSource), tipo });
            return metodoGenerico.Invoke(source, new object[] { source, lambda }) as IOrderedQueryable<TSource>;

        }

        public static IOrderedQueryable<TSource> ThenBy<TSource>(this IOrderedQueryable<TSource> source, string field, string dir = "asc")
        {
            var parametro = Expression.Parameter(typeof(TSource), "r");
            var expressao = Expression.Property(parametro, field);
            var lambda = Expression.Lambda<Func<TSource, string>>(expressao, parametro); // r => r.AlgumaCoisa
            var tipo = typeof(TSource).GetProperty(field).PropertyType;

            var nome = "ThenBy";
            if (string.Equals(dir, "desc", StringComparison.InvariantCultureIgnoreCase))
            {
                nome = "ThenByDescending";
            }

            var metodo = typeof(Queryable).GetMethods().First(m => m.Name == nome && m.GetParameters().Length == 2);
            var metodoGenerico = metodo.MakeGenericMethod(new[] { typeof(TSource), tipo });
            return metodoGenerico.Invoke(source, new object[] { source, lambda }) as IOrderedQueryable<TSource>;
        }

    }
}

Use :

example.OrderBy("Nome", "desc").ThenBy("other")

Work like:

example.OrderByDescending(r => r.Nome).ThenBy(r => r.other)

A process has code, data, heap and stack segments. Now, the Instruction Pointer (IP) of a thread OR threads points to the code segment of the process. The data and heap segments are shared by all the threads. Now what about the stack area? What is actually the stack area? Its an area created by the process just for its thread to use... because stacks can be used in a much faster way than heaps etc. The stack area of the process is divided among threads, i.e. if there are 3 threads, then the stack area of the process is divided into 3 parts and each is given to the 3 threads. In other words, when we say that each thread has its own stack, that stack is actually a part of the process stack area allocated to each thread. When a thread finishes its execution, the stack of the thread is reclaimed by the process. In fact, not only the stack of a process is divided among threads, but all the set of registers that a thread uses like SP, PC and state registers are the registers of the process. So when it comes to sharing, the code, data and heap areas are shared, while the stack area is just divided among threads.

As mentioned in comments above, the general case is a pain. It is fairly easy if all items are hashable or all items are sortable. However I have recently had to try solve the general case. Here is my solution. I realised after posting that this is a duplicate to a solution above that I missed on the first pass. Anyway, if you use slices rather than list.remove() you can compare immutable sequences.

def sequences_contain_same_items(a, b):
    for item in a:
        try:
            i = b.index(item)
        except ValueError:
            return False
        b = b[:i] + b[i+1:]
    return not b

Try something like this

jQuery

$('#toggle_icon').toggle(function() {

    $('#toggle_icon').text('-');
    $('#toggle_text').slideToggle();

}, function() {

    $('#toggle_icon').text('+');
    $('#toggle_text').slideToggle();

});

HTML

<a href="#" id="toggle_icon">+</a>

<div id="toggle_text" style="display: none">
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s
</div>

Epsilon is the value that the 2 numbers can be off by. So it will assert to true as long as Math.abs(expected - actual) < epsilon

Deleting a function is a C++11 feature:

The common idiom of "prohibiting copying" can now be expressed directly:

class X {
    // ...
    X& operator=(const X&) = delete;  // Disallow copying
    X(const X&) = delete;
};

[...]

The "delete" mechanism can be used for any function. For example, we can eliminate an undesired conversion like this:

struct Z {
    // ...

    Z(long long);     // can initialize with an long long         
    Z(long) = delete; // but not anything less
};

I was making a mistake like this, maybe it will help someone :)

If you use recyclerView.setAdapter every time new data come, it calls the adapter clear() method every time you use it, which causes the recyclerview to refresh and start over. To get rid of this, you need to use adapter.notiftyDatasetChanced().

An inner class cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?".

as u said here inner class cannot be static... i found the below code which is being given static....reason? or which is correct....

Yes, there is nothing in the semantics of a static nested type that would stop you from doing that. This snippet runs fine.

    public class MultipleInner {
        static class Inner {
        }   
    public static void main(String[] args) {
        for (int i = 0; i < 100; i++) {
            new Inner();
        }
    }
}

this is a code posted in this website...

for the question---> Can a Static Nested Class be Instantiated Multiple Times?

answer was--->

Now, of course the nested type can do its own instance control (e.g. private constructors, singleton pattern, etc) but that has nothing to do with the fact that it's a nested type. Also, if the nested type is a static enum, of course you can't instantiate it at all.

But in general, yes, a static nested type can be instantiated multiple times.

Note that technically, a static nested type is not an "inner" type.

There is already a correct answer from Adam, but you have another option to refactor your code:

if (Age.GetValueOrDefault() == 0)
{
    // it's null or 0
}

This would give you midnight on the first Sunday of the week:

DateTime t = DateTime.Now;
t -= new TimeSpan ((int) t.DayOfWeek, t.Hour, t.Minute, t.Second);

This gives you the first Monday at midnight:

DateTime t = DateTime.Now;
t -= new TimeSpan ((int) t.DayOfWeek - 1, t.Hour, t.Minute, t.Second);

Have you tried the import text function.

There is a way by which you can apply custom scrollbars to custom div elements in your HTML documents. Here is a an example which helps. https://codepen.io/adeelibr/pen/dKqZNb But as a gist of it. You can do something like this.

<div class="scrollbar" id="style-1">
  <div class="force-overflow"></div>
</div>

CSS file looks like this.

.scrollbar
{
  margin-left: 30px;
  float: left;
  height: 300px;
  width: 65px;
  background: #F5F5F5;
  overflow-y: scroll;
  margin-bottom: 25px;
}

.force-overflow
{
  min-height: 450px;
}

#style-1::-webkit-scrollbar-track
{
  -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
  border-radius: 10px;
  background-color: #F5F5F5;
}

#style-1::-webkit-scrollbar
{
  width: 12px;
  background-color: #F5F5F5;
}

#style-1::-webkit-scrollbar-thumb
{
  border-radius: 10px;
  -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
  background-color: #555;
}

See the (quite) recent answer on the matplotlib repository, in which the following solution is suggested:

• If you want to set the xticklabels:

  ax.set_xticks([1,4,5]) 
  ax.set_xticklabels([1,4,5], fontsize=12)
  

• If you want to only increase the fontsize of the xticklabels, using the default values and locations (which is something I personally often need and find very handy):

  ax.tick_params(axis="x", labelsize=12) 
  

• To do it all at once:

  plt.setp(ax.get_xticklabels(), fontsize=12, fontweight="bold", 
           horizontalalignment="left")`
  

In addition to what people wrote years ago:

• you might get this error on gcc/mingw:

main.c:30:3: warning: unknown conversion type character 'l' in format [-Wformat=]

printf("%llu\n", k);

Then your version of mingw does not default to c99. Add this compiler flag: -std=c99.

SimpleDateFormat sdf = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss" );

Using table aliases in the join condition:

update addresses a
set cid = b.id 
from customers b 
where a.id = b.id

list( myBigList[i] for i in [87, 342, 217, 998, 500] )

I compared the answers with python 2.5.2:

• 19.7 usec: [ myBigList[i] for i in [87, 342, 217, 998, 500] ]

• 20.6 usec: map(myBigList.__getitem__, (87, 342, 217, 998, 500))

• 22.7 usec: itemgetter(87, 342, 217, 998, 500)(myBigList)

• 24.6 usec: list( myBigList[i] for i in [87, 342, 217, 998, 500] )

Note that in Python 3, the 1st was changed to be the same as the 4th.

Another option would be to start out with a numpy.array which allows indexing via a list or a numpy.array:

>>> import numpy
>>> myBigList = numpy.array(range(1000))
>>> myBigList[(87, 342, 217, 998, 500)]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: invalid index
>>> myBigList[[87, 342, 217, 998, 500]]
array([ 87, 342, 217, 998, 500])
>>> myBigList[numpy.array([87, 342, 217, 998, 500])]
array([ 87, 342, 217, 998, 500])

The tuple doesn't work the same way as those are slices.

You need to specify the width and height in px:

width: 10px; height: 10px;

In addition, you can use overflow: auto; to prevent the horizontal scrollbar from showing.

Therefore, you may want to try the following:

<div style="width:100px; height:100px; overflow: auto;" >
  text text text text text text text text text
  text text text text text text text text text
  text text text text text text text text text
  text text text text text text text text text
  text text text text text text text text text
  text text text text text text text text text
  text text text text text text text text text
  text text text text text text text text text
</div>

Here is an update to the solution provided by @user235218 that allows you to specify number of milliseconds you require.

Note: The -n option is the number of retries and the -w is the timeout in milliseconds for ping. I chose the 127.255.255.254 address because it is in the loopback range and ms windows doesn’t respond to it.

I also doubt this will provide millisecond accuracy but on another note i tried it in an application using the ms script control and whilst the built in sleep function locked up the interface this method didn't.

If somebody can provide an explanation for why this method didn't lock up the interface we could make this answer more complete. Both sleep functions where run in the user thread.

Const WshHide = 0
Const WAIT_ON_RETURN = True

Sub Sleep(ByVal ms)

   Dim shell 'As WScript.Shell

   If Not IsNumeric(ms) Then _
       Exit Sub

   Set shell = CreateObject("WScript.Shell")

   Call shell.Run("%COMSPEC% /c ping -n 1 -w " & ms & " 127.255.255.254 > nul", WshHide, WAIT_ON_RETURN)

End Sub

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

Basically, I want to check if a particular string contains AT LEAST day(1 through 31 or 01 through 31),month(1 through 12 or 01 through 12) and year(yyyy or yy) in any order, with any date separator , what will be the solution? So, if the value includes any parts of time, it should return true too. I could NOT be able to define a array of format.

When I was in a similar situation, here is what I did:

1. Gather all the formats my system is expected to support.
2. Looked at what is common or can be generalize.
3. Learned to create REGEX (It is an investment of time initially but pays off once you create one or two on your own). Also do not try to build REGEX for all formats in one go, follow incremental process.
4. I created REGEX to cover as many format as possible.
5. For few cases, not to make REGEX extra complex, I covered it through DateTime.Parse() method.
6. With the combination of both Parse as well as REGEX i was able to validate the input is correct/as expected.

This http://www.codeproject.com/Articles/13255/Validation-with-Regular-Expressions-Made-Simple was really helpful both for understanding as well as validation the syntax for each format.

My 2 cents if it helps....

Just put a unicode newline character within the before pseudo element:

#restart:before { content: '\00000A'; }

Not in Linux at the moment, so can't double check, but I think it's:

rpm -ql ffmpeg

That should list all the files installed as part of the ffmpeg package.

I'm answering this question
What would be the equivalent for \p{Lu} or \p{Ll} in regExp for js?
since it was marked as an exact duplicate of the current old question.

Querying the UCD Database of Unicode 12, \p{Lu} generates 1,788 code points.

Converting to UTF-16 yields the class construct equivalency.
It's only a 4k character string and is easily doable in any regex engines.

Note that a regex implementation of \p{Lu} or \p{Pl} actually calls a
non standard function to test the value.

The character classes shown here are done differently and are linear, standard
and pretty slow, when jammed into mostly a single class.

Some insight on how a Regex engine (in general) implements Unicode Property Classes:

Examine these performance characteristics between the property
and the class block (like above)

Regex1:  LONG CLASS 
< none >
Completed iterations:   50  /  50     ( x 1 )
Matches found per iteration:   1788
Elapsed Time:    0.73 s,   727.58 ms,   727584 µs
Matches per sec:   122,872


Regex2:   \p{Lu}
Options:  < ICU - none >
Completed iterations:   50  /  50     ( x 1 )
Matches found per iteration:   1788
Elapsed Time:    0.07 s,   65.32 ms,   65323 µs
Matches per sec:   1,368,583

Wow what a difference !!

Lets see how Properties might be implemented

Array of Pointers [ 10FFFF ] where each index is is a Code Point

• Each pointer in the Array is to a structure of classification.

  • A Classification structure contains fixed field elemets.
    Some are NULL and do not pertain.
    Some contain category classifications.

    Example : General Category
    This is a bitmapped element that uses 17 out of 64 bits.
    Whatever this Code Point supports has bit(s) set as a mask.

    -Close_Punctuation
    -Connector_Punctuation
    -Control
    -Currency_Symbol
    -Dash_Punctuation
    -Decimal_Number
    -Enclosing_Mark
    -Final_Punctuation
    -Format
    -Initial_Punctuation
    -Letter_Number
    -Line_Separator
    -Lowercase_Letter
    -Math_Symbol
    -Modifier_Letter
    -Modifier_Symbol
    -Nonspacing_Mark
    -Open_Punctuation
    -Other_Letter
    -Other_Number
    -Other_Punctuation
    -Other_Symbol
    -Paragraph_Separator
    -Private_Use
    -Space_Separator
    -Spacing_Mark
    -Surrogate
    -Titlecase_Letter
    -Unassigned
    -Uppercase_Letter

When a regex is parsed with something like this \p{Lu} it
is translated directly into

• Classification Structure element offset : General Category
• A check of that element for bit item : Uppercase_Letter

Another example, when a regex is parsed with punctuation property \p{P} it
is translated into

• Classification Structure element offset : General Category

• A check of that element for any of these items bits, which are joined into a mask :

  -Close_Punctuation
  -Connector_Punctuation
  -Dash_Punctuation
  -Final_Punctuation
  -Initial_Punctuation
  -Open_Punctuation
  -Other_Punctuation

The offset and bit or bit(mask) are stored as a regex step for that property.

The lookup table is created once for all Unicode Code Points using this array.

When a character is checked, it is as simple as using the CP as an index into this array and checking the Classification Structure's specific element for that bit(mask).

This structure is expandable and indirect to provide much more complex look ups. This is just a simple example.

Compare that direct lookup with a character class search :

All classes are a linear list of items searched from left to right.
In this comparison, given our target string contains only the complete Upper Case Unicode Letters only, the law of averages would predict that half of the items in the class would have to be ranged checked to find a match.

This is a huge disadvantage in performance.

However, if the lookup tables are not there or are not up to date with the latest Unicode release (12 as of this date)
then this would be the only way.

In fact, it is mostly the only way to get the complete Emoji
characters as there is no specific property (or reasoning) to their assignment.

Using jQuery you can do:

$(window).width()
$(window).height()

I searched for the error in the web and came to this page. I am using Visual Studio 2015 and this is my first MVC project.

If you miss the @ symbol before the render section you will get the same error. I would like to share this for future beginners.

 @RenderSection("headscripts", required: false)

Note that this will not work:

header('Location: $url');

You need to do this (for variable expansion):

header("Location: $url");

Another solution is to implement your own custom popup/form/user control that will be universally interpreted across all browsers.

Granted this will not leverage the "mailto" out of the box capabilities. It all depends on what availability adherence you are working against. Unfortunately for myself - the mailto needed to be available to everyone by default without "inconveniencing the client".

Your decision ultimately.

Build a Python list and convert that to a Numpy array. That takes amortized O(1) time per append + O(n) for the conversion to array, for a total of O(n).

    a = []
    for x in y:
        a.append(x)
    a = np.array(a)

Personally I see an interface like a template. If a interface contains the definition for the methods foo() and bar(), then you know every class which uses this interface has the methods foo() and bar().

Your makefile should ideally be named makefile, not make. Note that you can call your makefile anything you like, but as you found, you then need the -f option with make to specify the name of the makefile. Using the default name of makefile just makes life easier.

This will leave the key as a string:

with open('infile.txt') as f:
  d = dict(x.rstrip().split(None, 1) for x in f)

I actually use a makefile to build any dependencies needed before invoking devenv to build a particular project as in the following:

debug: coratools_debug
    devenv coralib.vcproj /build debug

coratools_debug: nothing
    cd ../coratools
    nmake debug
    cd $(MAKEDIR)

You can also use the msbuild tool to do the same thing:

debug: coratools_debug
    msbuild coralib.vcxproj /p:Configuration=debug

coratools_debug: nothing
    cd ../coratools
    nmake debug
    cd $(MAKEDIR)

In my opinion, this is much easier than trying to figure out the overly complicated visual studio project management scheme.

It's a limitation of the language. In section 6.7.8/4:

All the expressions in an initializer for an object that has static storage duration shall be constant expressions or string literals.

In section 6.6, the spec defines what must considered a constant expression. No where does it state that a const variable must be considered a constant expression. It is legal for a compiler to extend this (6.6/10 - An implementation may accept other forms of constant expressions) but that would limit portability.

If you can change my_foo so it does not have static storage, you would be okay:

int main()
{
    foo_t my_foo = foo_init;
    return 0;
}

I have been experiencing this issue when debugging using NetBeans, even executing the actual jar file. Antivirus would block sending email. You should temporarily disable your antivirus during debugging or exclude NetBeans and the actual jar file from being scanned. In my case, I'm using Avast.

See this link on how to Exclude : How to Add File/Website Exception into avast! Antivirus 2014

It works for me.

A bit simpler one-liner:

import os
from itertools import product, chain

chain.from_iterable([[os.sep.join(w) for w in product([i[0]], i[2])] for i in os.walk(dir)])

For some others coming here:

In my case I had copied a .csproj from a sample project which included <EnableDefaultCompileItems>false</EnableDefaultCompileItems> without including the Program.cs file. Fix was to either remove EnableDefaultCompileItems or include Program.cs in the compile explicitly

My solution is very silly. I had tried all the solutions above and wasted so many hours. Then I found out the solution when I browsed developer options. I didn't check mark the "USB debugging" option. The silly me assumed turns on developer options mean turns on USB debugging, but I was wrong.

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

I came here with the same problem. For me (injecting hidden elements as needed - i.e. education in a job app) had the required flags.

What I realized was that the validator was firing on the injected faster than the document was ready, thus it complained.

My original ng-required tag was using the visibility tag (vm.flags.hasHighSchool).

I resolved by creating a dedicated flag to set required ng-required="vm.flags.highSchoolRequired == true"

I added a 10ms callback on setting that flag and the problem was solved.

 vm.hasHighSchool = function (attended) {

        vm.flags.hasHighSchool = attended;
        applicationSvc.hasHighSchool(attended, vm.application);
        setTimeout(function () {
            vm.flags.highSchoolRequired = true;;
        }, 10);
    }

Html:

<input type="text" name="vm.application.highSchool.name" data-ng-model="vm.application.highSchool.name" class="form-control" placeholder="Name *" ng-required="vm.flags.highSchoolRequired == true" /></div>

It does not work because your script in JSFiddle is running inside it's own scope (see the "OnLoad" drop down on the left?).

One way around this is to bind your event handler in javascript (where it should be):

document.getElementById('optionID').onchange = function () {
    document.getElementById("message").innerHTML = "Having a Baby!!";
};

Another way is to modify your code for the fiddle environment and explicitly declare your function as global so it can be found by your inline event handler:

window.changeMessage() {
    document.getElementById("message").innerHTML = "Having a Baby!!";
};

?

VC++ is not actually a language but is commonly referred to like one. When VC++ is referred to as a language, it usually means Microsoft's implementation of C++, which contains various knacks that do not exist in regular C++, such as the __super keyword. It is similar to the various GNU extensions to the C language that are implemented in GCC.

I shall try the solution with jQuery, for sure it should give a nice result. Of course you have to load jQuery ... What about a pop-up with something like this? Of course this is dependant on the user authorizing pop-ups.

<html>
    <head>
    <script language="javascript">
    var ret;
    function returnfunction()
    {
        alert(ret);
    }
    </script>
</head>
    <body>
        <form>
            <label id="QuestionToAsk" name="QuestionToAsk">Here is talked.</label><br />
            <input type="button" value="Yes" name="yes" onClick="ret=true;returnfunction()" />
            <input type="button" value="No" onClick="ret=false;returnfunction()" />
        </form>
    </body>
</html>

To serialize an object, do:

 using (StreamWriter myWriter = new StreamWriter(path, false))
 {
     XmlSerializer mySerializer = new XmlSerializer(typeof(your_object_type));
     mySerializer.Serialize(myWriter, objectToSerialize);
 }

Also remember that for XmlSerializer to work, you need a parameterless constructor.

The best bet with these types of questions is to see exactly what python does. The dis module is incredibly informative:

>>> import dis
>>> dis.dis("val != None")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               3 (!=)
              6 RETURN_VALUE
>>> dis.dis("not (val is None)")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               9 (is not)
              6 RETURN_VALUE

              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               9 (is not)
              6 RETURN_VALUE

Notice that the last two cases reduce to the same sequence of operations, Python reads not (val is None) and uses the is not operator. The first uses the != operator when comparing with None.

As pointed out by other answers, using != when comparing with None is a bad idea.

You CAN include a modal within a form. In the Bootstrap documentation it recommends the modal to be a "top level" element, but it still works within a form.

You create a form, and then the modal "save" button will be a button of type="submit" to submit the form from within the modal.

<form asp-action="AddUsersToRole" method="POST" class="mb-3">

    @await Html.PartialAsync("~/Views/Users/_SelectList.cshtml", Model.Users)

    <div class="modal fade" id="role-select-modal" tabindex="-1" role="dialog" aria-labelledby="role-select-modal" aria-hidden="true">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h5 class="modal-title" id="exampleModalLabel">Select a Role</h5>
                </div>
                <div class="modal-body">
                    ...
                </div>
                <div class="modal-footer">
                    <button type="submit" class="btn btn-primary">Add Users to Role</button>
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
                </div>
            </div>
        </div>
    </div>

</form>

You can post (or GET) your form data to any URL. By default it is the serving page URL, but you can change it by setting the form action. You do not have to use ajax.

Mozilla documentation on form action

The cc and cxx is located inside /Applications/Xcode.app. This should find the right paths

export CXX=`xcrun -find c++`
export CC=`xcrun -find cc`

You should be able to access the document in the IFRAME using the following code:

document.getElementById('myframe').contentWindow.document

However, you will not be able to do this if the page in the frame is loaded from a different domain (such as google.com). THis is because of the browser's Same Origin Policy.

firstly, in your main page use a loading icon

then, delete your </body> and </HTML> from your main page and replace it by

<?php include('footer.php');?>

in the footer.php file type :

<?php
    $iconPath="myIcon.ico" // myIcon is the final icon
    echo '<script>changeIcon($iconPath)</script>'; // where changeIcon is a javascript function whiwh change your icon.
    echo '</body>';
    echo '</HTML>';
?>

If you're in VB 9 (VS2008), a predicate can be a complex function:

Dim list As New List(Of Integer)(New Integer() {1, 2, 3})
Dim newList = list.FindAll(AddressOf GreaterThanTwo)
...
Function GreaterThanTwo(ByVal item As Integer) As Boolean
    'do some work'
    Return item > 2
End Function

Or you can write your predicate as a lambda, as long as it's only one expression:

Dim list As New List(Of Integer)(New Integer() {1, 2, 3})
Dim newList = list.FindAll(Function(item) item > 2)

what you proposed with a change at the parenthesis at the Run command worked fine with VBA for me

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
Dim errorCode As Integer
wsh.Run "C:\folder\runbat.bat", windowStyle, waitOnReturn

An alternative is Joda-Time.

Use DateTime

DateTime date = new DateTime(new Date());
date.isBeforeNow();
or
date.isAfterNow();

Place the wkhtmltopdf executable on the server and chmod it +x.

Create an executable shell script wrap.sh containing:

#!/bin/sh
export HOME="$PWD"
export LD_LIBRARY_PATH="$PWD/lib/"
exec $@ 2>/dev/null
#exec $@ 2>&1 # debug mode

Download needed shared objects for that architecture and place them an a folder named "lib":

• lib/libfontconfig.so.1
• lib/libfontconfig.so.1.3.0
• lib/libfreetype.so.6
• lib/libfreetype.so.6.3.18
• lib/libX11.so.6 lib/libX11.so.6.2.0
• lib/libXau.so.6 lib/libXau.so.6.0.0
• lib/libxcb.so.1 lib/libxcb.so.1.0.0
• lib/libxcb-xlib.so.0
• lib/libxcb-xlib.so.0.0.0
• lib/libXdmcp.so.6
• lib/libXdmcp.so.6.0.0
• lib/libXext.so.6 lib/libXext.so.6.4.0

(some of them are symlinks)

… and you're ready to go:

./wrap.sh ./wkhtmltopdf-amd64 --page-size A4 --disable-internal-links --disable-external-links "http://www.example.site/" out.pdf

If you experience font problems like squares for all the characters, define TrueType fonts explicitly:

@font-face {
  font-family:Trebuchet MS;
  font-style:normal;
  font-weight:normal;
  src:url("http://www.yourserver.tld/fonts/Trebuchet_MS.ttf");
  format(TrueType);
}

Send a Location header to redirect. Keep in mind this only works before any other output is sent.

header('Location: index.php'); // redirect to index.php

Get private variable's value using Reflection:

var _barVariable = typeof(Foo).GetField("_bar", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(objectForFooClass);

Set value for private variable using Reflection:

typeof(Foo).GetField("_bar", BindingFlags.NonPublic | BindingFlags.Instance).SetValue(objectForFoocClass, "newValue");

Where objectForFooClass is a non null instance for the class type Foo.

Just use a two color background image:

<div style="width:100%; background:url('images/bkgmid.png');
       background-size: cover;">
content
</div>

Here are the steps you need. Step5 is important if you want the data. Step 2 is where you can select individual tables.

EDIT stack's version isn't quite readable... here's a full-size image http://i.imgur.com/y6ZCL.jpg

You should check out scipy.sparse. You can apply operations on those sparse matrices just like how you use a normal matrix.

Different Idea:

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

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

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

Code:

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

I've got the same exception and in my case the problem was in a renegotiation procecess. In fact my client closed a connection when the server tried to change a cipher suite. After digging it appears that in the jdk 1.6 update 22 renegotiation process is disabled by default. If your security constraints can effort this, try to enable the unsecure renegotiation by setting the sun.security.ssl.allowUnsafeRenegotiation system property to true. Here is some information about the process:

Session renegotiation is a mechanism within the SSL protocol that allows the client or the server to trigger a new SSL handshake during an ongoing SSL communication. Renegotiation was initially designed as a mechanism to increase the security of an ongoing SSL channel, by triggering the renewal of the crypto keys used to secure that channel. However, this security measure isn't needed with modern cryptographic algorithms. Additionally, renegotiation can be used by a server to request a client certificate (in order to perform client authentication) when the client tries to access specific, protected resources on the server.

Additionally there is the excellent post about this issue in details and written in (IMHO) understandable language.

The '\r' stands for "Carriage Return" - it's a holdover from the days of typewriters and really old printers. The best example is in Windows and other DOSsy OSes, where a newline is given as "\r\n". These are the instructions sent to an old printer to start a new line: first move the print head back to the beginning, then go down one.

Different OSes will use other newline sequences. Linux and OSX just use '\n'. Older Mac OSes just use '\r'. Wikipedia has a more complete list, but those are the important ones.

Hope this helps!

PS: As for why you get that weird output... Perhaps the console is moving the "cursor" back to the beginning of the line, and then overwriting the first bit with spaces or summat.

Ensure your libcurl.so module is in the system library path, which is distinct and separate from the python library path.

A "quick fix" is to add this path to a LD_LIBRARY_PATH variable. However, setting that system wide (or even account wide) is a BAD IDEA, as it is possible to set it in such a way that some programs will find a library it shouldn't, or even worse, open up security holes.

If your "locally installed libraries" are installed in, for example, /usr/local/lib, add this directory to /etc/ld.so.conf (it's a text file) and run "ldconfig"

The command will run a caching utility, but will also create all the necessary "symbolic links" required for the loader system to function. It is surprising that the "make install" for libcurl did not do this already, but it's possible it could not if /usr/local/lib is not in /etc/ld.so.conf already.

PS: it's possible that your /etc/ld.so.conf contains nothing but "include ld.so.conf.d/*.conf". You can still add a directory path after it, or just create a new file inside the directory it's being included from. Dont forget to run "ldconfig" after it.

Be careful. Getting this wrong can screw up your system.

Additionally: make sure your python module is compiled against THAT version of libcurl. If you just copied some files over from another system, this wont always work. If in doubt, compile your modules on the system you intend to run them on.

Try this

 <input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden">

select * from pg_tables where schemaname = 'information_schema'

In generall pg* tables allow you to see everything in the db, not constrained to your permissions (if you have access to the tables of course).

mapStateToProps() is a utility which helps your component get updated state(which is updated by some other components),
mapDispatchToProps() is a utility which will help your component to fire an action event (dispatching action which may cause change of application state)

There is a bug in Chrome (not in Safari at the time we checked) that gives unexpected results in Javascript's various width and height measurements when opening tabs in the background (bug details here) - we logged the bug in June and it's remained unresolved since.

It's possible you've encountered the bug in what you're attempting to do.

Ruby has two other loop/iteration control keywords: redo and retry. Read more about them, and the difference between them, at Ruby QuickTips.

Just remove the comma like this:

I've implemented a cache which helped to reduce number of recursions. This cache will avoid scanning of letters that it had already done for previous combinations. For one instance it was going for 120k loops, after cache implementation it got reduced to 40k.

private List<String> generateWords(String phoneNumber) {

    List<String> words = new LinkedList<String>();
    List<String> wordsCache = new LinkedList<String>();

    this.generatePossibleWords("", phoneNumber, words, wordsCache);

    return words;
}

private void generatePossibleWords(String prefix, String remainder,

    int index = Integer.parseInt(remainder.substring(0, 1));

    for (int i = 0; i < phoneKeyMapper.get(index).size(); i++) {

        String mappedChar = phoneKeyMapper.get(index).get(i);

        if (prefix.equals("") && !wordsCache.isEmpty()) {

            for (String word : wordsCache) {
                words.add(mappedChar + word);
            }
        } else {

            if (remainder.length() == 1) {
                String stringToBeAdded = prefix + mappedChar;
                words.add(stringToBeAdded);
                wordsCache.add(stringToBeAdded.substring(1));
                LOGGER.finest("adding stringToBeAdded = " + stringToBeAdded.substring(1));

            } else {
                generatePossibleWords(prefix + mappedChar,
                remainder.substring(1), words, wordsCache);
            }
        }
    }
}

Pipe the output through less or other pager:

svn log | less

for (var key in myMap) {
    if (myMap.hasOwnProperty(key)) {
        console.log("key =" + key);
        console.log("value =" + myMap[key]);
    }
}

In javascript, every object has a bunch of built-in key-value pairs that have meta-information. When you loop through all the key-value pairs for an object you're looping through them too. The use of hasOwnProperty() filters these out.

I found it short and simple, and can be tested in Dev Tool console itself.

$('#id option').each( (index,element)=>console.log( index : ${index}, value : ${element.value}, text : ${element.text}) )

Your file has syntax error, so your file was not interpreted, so settings was not changed and you have blank page.

You can separate your file to two.

index.php

<?php
ini_set("display_errors", "1");
error_reporting(E_ALL);
include 'error.php';

error.php

<?
echo('catch this -> ' ;. $thisdoesnotexist);

I had a similar problem today and found refactoring the conditional logic into a separate function to help.

I find it more readable than the labels and people are more comfortable with return than break. Inline functions are similar but the indentation can get a bit confusing.

In your case it would look like this.

function doThing() {
  checkConditions();

  // Rest of the code here
}

function checkConditions() {
  if (c1) {
    if (c2) {
      return do1();
    else {
      return;
    }
  } else {
    return do3();
  }
}

What about this?
