Programs & Examples On #Iso8601

It seems important to exactly match the format of the ISO string for TryParseExact to work. I guess Exact is Exact and this answer is obvious to most but anyway...

In my case, Reb.Cabin's answer doesn't work as I have a slightly different input as per my "value" below.

Value: 2012-08-10T14:00:00.000Z

There are some extra 000's in there for milliseconds and there may be more.

However if I add some .fff to the format as shown below, all is fine.

Format String: @"yyyy-MM-dd\THH:mm:ss.fff\Z"

In VS2010 Immediate Window:

DateTime.TryParseExact(value,@"yyyy-MM-dd\THH:mm:ss.fff\Z", CultureInfo.InvariantCulture,DateTimeStyles.AssumeUniversal, out d);

true

You may have to use DateTimeStyles.AssumeLocal as well depending upon what zone your time is for...

Both ways:

Epoch to ISO time:

isoTime = time.strftime('%Y-%m-%dT%H:%M:%SZ', time.gmtime(epochTime))

ISO time to Epoch:

epochTime = time.mktime(time.strptime(isoTime, '%Y-%m-%dT%H:%M:%SZ'))

Option: isoformat()

Python's datetime does not support the military timezone suffixes like 'Z' suffix for UTC. The following simple string replacement does the trick:

In [1]: import datetime

In [2]: d = datetime.datetime(2014, 12, 10, 12, 0, 0)

In [3]: str(d).replace('+00:00', 'Z')
Out[3]: '2014-12-10 12:00:00Z'

str(d) is essentially the same as d.isoformat(sep=' ')

See: Datetime, Python Standard Library

Option: strftime()

Or you could use strftime to achieve the same effect:

In [4]: d.strftime('%Y-%m-%dT%H:%M:%SZ')
Out[4]: '2014-12-10 12:00:00Z'

Note: This option works only when you know the date specified is in UTC.

See: datetime.strftime()

Additional: Human Readable Timezone

Going further, you may be interested in displaying human readable timezone information, pytz with strftime %Z timezone flag:

In [5]: import pytz

In [6]: d = datetime.datetime(2014, 12, 10, 12, 0, 0, tzinfo=pytz.utc)

In [7]: d
Out[7]: datetime.datetime(2014, 12, 10, 12, 0, tzinfo=<UTC>)

In [8]: d.strftime('%Y-%m-%d %H:%M:%S %Z')
Out[8]: '2014-12-10 12:00:00 UTC'

This seemed to work best for me:

public static Date fromISO8601_( String string ) {

    try {
            return new SimpleDateFormat ( "yyyy-MM-dd'T'HH:mm:ssXXX").parse ( string );
    } catch ( ParseException e ) {
        return Exceptions.handle (Date.class, "Not a valid ISO8601", e);
    }


}

I needed to convert to/fro JavaScript date strings to Java. I found the above works with the recommendation. There were some examples using SimpleDateFormat that were close but they did not seem to be the subset as recommended by:

http://www.w3.org/TR/NOTE-datetime

and supported by PLIST and JavaScript Strings and such which is what I needed.

This seems to be the most common form of ISO8601 string out there, and a good subset.

The examples they give are:

1994-11-05T08:15:30-05:00 corresponds 
November 5, 1994, 8:15:30 am, US Eastern Standard Time.

 1994-11-05T13:15:30Z corresponds to the same instant.

I also have a fast version:

final static int SHORT_ISO_8601_TIME_LENGTH =  "1994-11-05T08:15:30Z".length ();
                                            // 01234567890123456789012
final static int LONG_ISO_8601_TIME_LENGTH = "1994-11-05T08:15:30-05:00".length ();


public static Date fromISO8601( String string ) {
    if (isISO8601 ( string )) {
        char [] charArray = Reflection.toCharArray ( string );//uses unsafe or string.toCharArray if unsafe is not available
        int year = CharScanner.parseIntFromTo ( charArray, 0, 4 );
        int month = CharScanner.parseIntFromTo ( charArray, 5, 7 );
        int day = CharScanner.parseIntFromTo ( charArray, 8, 10 );
        int hour = CharScanner.parseIntFromTo ( charArray, 11, 13 );

        int minute = CharScanner.parseIntFromTo ( charArray, 14, 16 );

        int second = CharScanner.parseIntFromTo ( charArray, 17, 19 );

        TimeZone tz ;

         if (charArray[19] == 'Z') {

             tz = TimeZone.getTimeZone ( "GMT" );
         } else {

             StringBuilder builder = new StringBuilder ( 9 );
             builder.append ( "GMT" );
             builder.append( charArray, 19, LONG_ISO_8601_TIME_LENGTH - 19);
             String tzStr = builder.toString ();
             tz = TimeZone.getTimeZone ( tzStr ) ;

         }
         return toDate ( tz, year, month, day, hour, minute, second );

    }   else {
        return null;
    }

}

...

public static int parseIntFromTo ( char[] digitChars, int offset, int to ) {
    int num = digitChars[ offset ] - '0';
    if ( ++offset < to ) {
        num = ( num * 10 ) + ( digitChars[ offset ] - '0' );
        if ( ++offset < to ) {
            num = ( num * 10 ) + ( digitChars[ offset ] - '0' );
            if ( ++offset < to ) {
                num = ( num * 10 ) + ( digitChars[ offset ] - '0' );
                if ( ++offset < to ) {
                    num = ( num * 10 ) + ( digitChars[ offset ] - '0' );
                    if ( ++offset < to ) {
                        num = ( num * 10 ) + ( digitChars[ offset ] - '0' );
                        if ( ++offset < to ) {

                                if ( ++offset < to ) {
                                    num = ( num * 10 ) + ( digitChars[ offset ] - '0' );
                                }
                            }
                        }
                    }
                }
            }
        }
    }
    return num;
}


public static boolean isISO8601( String string ) {
      boolean valid = true;

      if (string.length () == SHORT_ISO_8601_TIME_LENGTH) {
          valid &=  (string.charAt ( 19 )  == 'Z');

      } else if (string.length () == LONG_ISO_8601_TIME_LENGTH) {
          valid &=  (string.charAt ( 19 )  == '-' || string.charAt ( 19 )  == '+');
          valid &=  (string.charAt ( 22 )  == ':');

      } else {
          return false;
      }

    //  0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4
    // "1 9 9 4 - 1 1 - 0 5 T 0 8 : 1 5 : 3 0 - 0 5 : 0 0

    valid &=  (string.charAt ( 4 )  == '-') &&
                (string.charAt ( 7 )  == '-') &&
                (string.charAt ( 10 ) == 'T') &&
                (string.charAt ( 13 ) == ':') &&
                (string.charAt ( 16 ) == ':');

    return valid;
}

I have not benchmarked it, but I am guess it will be pretty fast. It seems to work. :)

@Test
public void testIsoShortDate() {
    String test =  "1994-11-05T08:15:30Z";

    Date date = Dates.fromISO8601 ( test );
    Date date2 = Dates.fromISO8601_ ( test );

    assertEquals(date2.toString (), date.toString ());

    puts (date);
}

@Test
public void testIsoLongDate() {
    String test =  "1994-11-05T08:11:22-05:00";

    Date date = Dates.fromISO8601 ( test );
    Date date2 = Dates.fromISO8601_ ( test );

    assertEquals(date2.toString (), date.toString ());

    puts (date);
}

If you just want the date portion (e.g. 2017-06-27), and you want it to work regardless of time zone and also in Arabic, here is code I wrote:

function isoDate(date) {
    if (!date) {
        return null
    }
    date = moment(date).toDate()

    // don't call toISOString because it takes the time zone into
    // account which we don't want.  Also don't call .format() because it
    // returns Arabic instead of English

    var month = 1 + date.getMonth()
    if (month < 10) {
        month = '0' + month
    }
    var day = date.getDate()
    if (day < 10) {
        day = '0' + day
    }
    return date.getFullYear() + '-' + month + '-' + day
}

Thanks acdcjunior for your solution. Here's a little optimized version for formatting and parsing :

public static final SimpleDateFormat XML_SDF = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.FRANCE)
{
    private static final long serialVersionUID = -8275126788734707527L;

    public StringBuffer format(Date date, StringBuffer toAppendTo, java.text.FieldPosition pos)
    {            
        final StringBuffer buf = super.format(date, toAppendTo, pos);
        buf.insert(buf.length() - 2, ':');
        return buf;
    };

    public Date parse(String source) throws java.text.ParseException {
        final int split = source.length() - 2;
        return super.parse(source.substring(0, split - 1) + source.substring(split)); // replace ":" du TimeZone
    };
};

Update for Java 8 and higher

You can now simply do Instant.parse("2015-04-28T14:23:38.521Z") and get the correct thing now, especially since you should be using Instant instead of the broken java.util.Date with the most recent versions of Java.

You should be using DateTimeFormatter instead of SimpleDateFormatter as well.

Original Answer:

The explanation below is still valid as as what the format represents. But it was written before Java 8 was ubiquitous so it uses the old classes that you should not be using if you are using Java 8 or higher.

This works with the input with the trailing Z as demonstrated:

In the pattern the T is escaped with ' on either side.

The pattern for the Z at the end is actually XXX as documented in the JavaDoc for SimpleDateFormat, it is just not very clear on actually how to use it since Z is the marker for the old TimeZone information as well.

Remember to set the locale to en_US_POSIX as described in Technical Q&A1480. In Swift 3:

let date = Date()
let formatter = DateFormatter()
formatter.locale = Locale(identifier: "en_US_POSIX")
formatter.timeZone = TimeZone(secondsFromGMT: 0)
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ"
print(formatter.string(from: date))

The issue is that if you're on a device which is using a non-Gregorian calendar, the year will not conform to RFC3339/ISO8601 unless you specify the locale as well as the timeZone and dateFormat string.

Or you can use ISO8601DateFormatter to get you out of the weeds of setting locale and timeZone yourself:

let date = Date()
let formatter = ISO8601DateFormatter()
formatter.formatOptions.insert(.withFractionalSeconds)  // this is only available effective iOS 11 and macOS 10.13
print(formatter.string(from: date))

For Swift 2 rendition, see previous revision of this answer.

If you don't want to use dateutil, you can try this function:

def from_utc(utcTime,fmt="%Y-%m-%dT%H:%M:%S.%fZ"):
    """
    Convert UTC time string to time.struct_time
    """
    # change datetime.datetime to time, return time.struct_time type
    return datetime.datetime.strptime(utcTime, fmt)

Test:

from_utc("2007-03-04T21:08:12.123Z")

Result:

datetime.datetime(2007, 3, 4, 21, 8, 12, 123000)

If you're developing under SharePoint 2010 or higher you can use

using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
...
string strISODate = SPUtility.CreateISO8601DateTimeFromSystemDateTime(DateTime.Now)

Looks like moment.js is the most popular and with active development:

moment("2010-01-01T05:06:07", moment.ISO_8601);

The question asked was ISO format with reduced precision. Voila:

 new Date().toISOString().slice(0, 19) + 'Z'
 // '2014-10-23T13:18:06Z'

Assuming the trailing Z is wanted, otherwise just omit.

Local to ISO 8601:

import datetime
datetime.datetime.now().isoformat()
>>> 2020-03-20T14:28:23.382748

UTC to ISO 8601:

import datetime
datetime.datetime.utcnow().isoformat()
>>> 2020-03-20T01:30:08.180856

Local to ISO 8601 without microsecond:

import datetime
datetime.datetime.now().replace(microsecond=0).isoformat()
>>> 2020-03-20T14:30:43

UTC to ISO 8601 with TimeZone information (Python 3):

import datetime
datetime.datetime.utcnow().replace(tzinfo=datetime.timezone.utc).isoformat()
>>> 2020-03-20T01:31:12.467113+00:00

UTC to ISO 8601 with Local TimeZone information without microsecond (Python 3):

import datetime
datetime.datetime.now().astimezone().replace(microsecond=0).isoformat()
>>> 2020-03-20T14:31:43+13:00

Local to ISO 8601 with TimeZone information (Python 3):

import datetime
datetime.datetime.now().astimezone().isoformat()
>>> 2020-03-20T14:32:16.458361+13:00

Notice there is a bug when using astimezone() on utc time. This gives an incorrect result:

datetime.datetime.utcnow().astimezone().isoformat() #Incorrect result

For Python 2, see and use pytz.

INNER JOIN gets all records that are common between both tables based on the supplied ON clause.

LEFT JOIN gets all records from the LEFT linked and the related record from the right table ,but if you have selected some columns from the RIGHT table, if there is no related records, these columns will contain NULL.

RIGHT JOIN is like the above but gets all records in the RIGHT table.

FULL JOIN gets all records from both tables and puts NULL in the columns where related records do not exist in the opposite table.

mtrakal's solution worked fine.

Added to gradle.build:

buildscript {
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha2'

        // NOTE: Do not place your application dependencies here; 
        // they belong in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Then it automatically upgraded to alpha2.

Invalidate the caches and restarted all is fine.

File | Invalidate Caches / Restart

choose 'Invalidate & Restart'

This should do it:

HTML

<input name="Name" value="Enter Your Name" onClick="blankDefault('Enter Your Name', this)">

JavaScript

function blankDefault(_text, _this) {
    if(_text == _this.value)
        _this.value = '';
}

There are better/less obtrusive ways though, but this will get the job done.

for n in range(6,0,-1)

This would give you 6,5,4,3,2,1

As for

for n in reversed(range(0,6))

would give you 5,4,3,2,1,0

"??".encode('utf-8')

encode converts a unicode object to a string object. But here you have invoked it on a string object (because you don't have the u). So python has to convert the string to a unicode object first. So it does the equivalent of

"??".decode().encode('utf-8')

But the decode fails because the string isn't valid ascii. That's why you get a complaint about not being able to decode.

"Valid Signing identity not found" This is because you don't have the private key for distribution certificate.

If the distribution certificate was created originally on a different Mac you may need to import this private key from that Mac. This private key is not available to download from your provisioning portal.

When you import the correct private key to your mac , XCode's organizer will recognize your already downloaded distribution profile as a "Valid profile"

However if you do not have access to the original Mac which created those profiles, the only option you have is revoking profiles.

A clearer solution, works in ASP.Net Core 2.1 / 3.1

Filter class

using Microsoft.AspNetCore.Authorization;
// For ASP.NET 2.1
using Microsoft.AspNetCore.Http.Internal;
// For ASP.NET 3.1
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc.Filters;

public class ReadableBodyStreamAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationFilterContext context)
    {
        // For ASP.NET 2.1
        // context.HttpContext.Request.EnableRewind();
        // For ASP.NET 3.1
        // context.HttpContext.Request.EnableBuffering();
    }
}

In an Controller

[HttpPost]
[ReadableBodyStream]
public string SomePostMethod()
{
    //Note: if you're late and body has already been read, you may need this next line
    //Note2: if "Note" is true and Body was read using StreamReader too, then it may be necessary to set "leaveOpen: true" for that stream.
    HttpContext.Request.Body.Seek(0, SeekOrigin.Begin);

    using (StreamReader stream = new StreamReader(HttpContext.Request.Body))
    {
        string body = stream.ReadToEnd();
        // body = "param=somevalue&param2=someothervalue"
    }
}

Haven't tested it, but that should alert the blobs data url:

var blob = event.clipboardData.items[0].getAsFile(), 
    form = new FormData(),
    request = new XMLHttpRequest();

var reader = new FileReader();
reader.onload = function(event) {
  alert(event.target.result); // <-- data url
};
reader.readAsDataURL(blob);

Alternatively you can have your class implement the InitializingBean interface to provide a callback function (afterPropertiesSet()) which the ApplicationContext will invoke when the bean is constructed.

For any dialog called myDialog, after calling myDialog.show(); you can call:

myDialog.getWindow().getDecorView().getBackground().setColorFilter(new LightingColorFilter(0xFF000000, CUSTOM_COLOR));

where CUSTOM_COLOR is in 8-digit hex format, ex. 0xFF303030. Here, FF is the alpha value and the rest is the color value in hex.

In newer versions of matplotlib, if you do not set the tick labels with a bunch of str values, they are '' by default (and when the plot is draw the labels are simply the ticks values). Knowing that, to get your desired output would require something like this:

>>> from pylab import *
>>> axes = figure().add_subplot(111)
>>> a=axes.get_xticks().tolist()
>>> a[1]='change'
>>> axes.set_xticklabels(a)
[<matplotlib.text.Text object at 0x539aa50>, <matplotlib.text.Text object at 0x53a0c90>, 
<matplotlib.text.Text object at 0x53a73d0>, <matplotlib.text.Text object at 0x53a7a50>, 
<matplotlib.text.Text object at 0x53aa110>, <matplotlib.text.Text object at 0x53aa790>]
>>> plt.show()

and the result:

and now if you check the _xticklabels, they are no longer a bunch of ''.

>>> [item.get_text() for item in axes.get_xticklabels()]
['0.0', 'change', '1.0', '1.5', '2.0']

It works in the versions from 1.1.1rc1 to the current version 2.0.

i had got the same error. Actually i tried to override the flutter Old SDK Package with new Updated Package. so that error occurred.

i opened flutter sdk directory with VS Code and cleaned the project

use this code in VSCode cmd

git clean -dxf

then use git pull

var jsonData = [{"person":"me","age":"30"},{"person":"you","age":"25"}];

for(var i in jsonData){
    var key = i;
    var val = jsonData[i];
    for(var j in val){
        var sub_key = j;
        var sub_val = val[j];
        console.log(sub_key);
    }
}

EDIT

var jsonObj = {"person":"me","age":"30"};
Object.keys(jsonObj);  // returns ["person", "age"]

Object has a property keys, returns an Array of keys from that Object

Chrome, FF & Safari supports Object.keys

I used @media \0screen {} and it works fine for me in REAL IE8.

var idList=new int[]{1, 2, 3, 4};
var friendsToUpdate = await Context.Friends.Where(f => 
    idList.Contains(f.Id).ToListAsync();

foreach(var item in previousEReceipts)
{
  item.msgSentBy = "1234";
}

You can use foreach to update each element that meets your condition.

Here is an example in a more generic way:

var itemsToUpdate = await Context.friends.Where(f => f.Id == <someCondition>).ToListAsync();

foreach(var item in itemsToUpdate)
{
   item.property = updatedValue;
}
Context.SaveChanges()

In general you will most probably use async methods with await for db queries.

See regex101.com

To read a property of an object you use .propertyName or ["propertyName"] notation.

This is no different for elements.

var name = $('#item')[0].name;
var name = $('#item')[0]["name"];

If you specifically want to use jQuery methods, then you'd use the .prop() method.

var name = $('#item').prop('name');

Please note that attributes and properties are not necessarily the same.

If you know your regional settings won't change you can do it as follows:

• if your short date format is dd/MM/yyyy:

  SET MYDATE=%DATE:~3,2%%DATE:~0,2%%DATE:~8,4%

• if your short date format is MM/dd/yyyy:

  SET MYDATE=%DATE:~0,2%%DATE:~3,2%%DATE:~8,4%

But there's no general way to do it that's independent of your regional settings.

I would not recommend relying on regional settings for anything that's going to be used in a production environment. Instead you should consider using another scripting language - PowerShell, VBScript, ...

For example, if you create a VBS file yyyymmdd.vbs in the same directory as your batch file with the following contents:

' yyyymmdd.vbs - outputs the current date in the format yyyymmdd
Function Pad(Value, PadCharacter, Length)
    Pad = Right(String(Length,PadCharacter) & Value, Length)
End Function

Dim Today
Today = Date
WScript.Echo Pad(Year(Today), "0", 4) & Pad(Month(Today), "0", 2) & Pad(Day(Today), "0", 2)

then you will be able to call it from your batch file thus:

FOR /F %%i IN ('cscript "%~dp0yyyymmdd.vbs" //Nologo') do SET MYDATE=%%i
echo %MYDATE%

Of course there will eventually come a point where rewriting your batch file in a more powerful scripting language will make more sense than mixing it with VBScript in this way.

For globally-installed modules:

The other answers give you platform-specific responses, but a generic one is this:

When you install global module with npm install -g something, npm looks up a config variable prefix to know where to install the module.

You can get that value by running npm config get prefix

To display all the global modules available in that folder use npm ls -g --depth 0 (depth 0 to not display their dependencies).

If you want to change the global modules path, use npm config edit and put prefix = /my/npm/global/modules/prefix in the file or use npm config set prefix /my/npm/global/modules/prefix.

When you use some tools like nodist, they change the platform-default installation path of global npm modules.

In your ASPX page you've got the list like this:

    <asp:CheckBoxList ID="YrChkBox" runat="server" 
        onselectedindexchanged="YrChkBox_SelectedIndexChanged"></asp:CheckBoxList>
    <asp:Button ID="button" runat="server" Text="Submit" />

In your code behind aspx.cs page, you have this:

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            // Populate the CheckBoxList items only when it's not a postback.
            YrChkBox.Items.Add(new ListItem("Item 1", "Item1"));
            YrChkBox.Items.Add(new ListItem("Item 2", "Item2"));
        }
    }

    protected void YrChkBox_SelectedIndexChanged(object sender, EventArgs e)
    {
        // Create the list to store.
        List<String> YrStrList = new List<string>();
        // Loop through each item.
        foreach (ListItem item in YrChkBox.Items)
        {
            if (item.Selected)
            {
                // If the item is selected, add the value to the list.
                YrStrList.Add(item.Value);
            }
            else
            {
                // Item is not selected, do something else.
            }
        }
        // Join the string together using the ; delimiter.
        String YrStr = String.Join(";", YrStrList.ToArray());

        // Write to the page the value.
        Response.Write(String.Concat("Selected Items: ", YrStr));
    }

Ensure you use the if (!IsPostBack) { } condition because if you load it every page refresh, it's actually destroying the data.

Breadth first search

Queue<TreeNode> queue = new LinkedList<BinaryTree.TreeNode>() ;
public void breadth(TreeNode root) {
    if (root == null)
        return;
    queue.clear();
    queue.add(root);
    while(!queue.isEmpty()){
        TreeNode node = queue.remove();
        System.out.print(node.element + " ");
        if(node.left != null) queue.add(node.left);
        if(node.right != null) queue.add(node.right);
    }

}

width, height = map(int, input().split())
def rectanglePerimeter(width, height):
   return ((width + height)*2)
print(rectanglePerimeter(width, height))

Running it like this produces:

% echo "1 2" | test.py
6

I suspect IDLE is simply passing a single string to your script. The first input() is slurping the entire string. Notice what happens if you put some print statements in after the calls to input():

width = input()
print(width)
height = input()
print(height)

Running echo "1 2" | test.py produces

1 2
Traceback (most recent call last):
  File "/home/unutbu/pybin/test.py", line 5, in <module>
    height = input()
EOFError: EOF when reading a line

Notice the first print statement prints the entire string '1 2'. The second call to input() raises the EOFError (end-of-file error).

So a simple pipe such as the one I used only allows you to pass one string. Thus you can only call input() once. You must then process this string, split it on whitespace, and convert the string fragments to ints yourself. That is what

width, height = map(int, input().split())

does.

Note, there are other ways to pass input to your program. If you had run test.py in a terminal, then you could have typed 1 and 2 separately with no problem. Or, you could have written a program with pexpect to simulate a terminal, passing 1 and 2 programmatically. Or, you could use argparse to pass arguments on the command line, allowing you to call your program with

test.py 1 2

Here is another possible solution, using the resolve attribute of the $stateProvider or the $routeProvider. Example with $stateProvider:

.config(["$stateProvider", function ($stateProvider) {

  $stateProvider

  .state("forbidden", {
    /* ... */
  })

  .state("signIn", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.isAnonymous(); }],
    }
  })

  .state("home", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.isAuthenticated(); }],
    }
  })

  .state("admin", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.hasRole("ROLE_ADMIN"); }],
    }
  });

}])

Access resolves or rejects a promise depending on the current user rights:

.factory("Access", ["$q", "UserProfile", function ($q, UserProfile) {

  var Access = {

    OK: 200,

    // "we don't know who you are, so we can't say if you're authorized to access
    // this resource or not yet, please sign in first"
    UNAUTHORIZED: 401,

    // "we know who you are, and your profile does not allow you to access this resource"
    FORBIDDEN: 403,

    hasRole: function (role) {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$hasRole(role)) {
          return Access.OK;
        } else if (userProfile.$isAnonymous()) {
          return $q.reject(Access.UNAUTHORIZED);
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    hasAnyRole: function (roles) {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$hasAnyRole(roles)) {
          return Access.OK;
        } else if (userProfile.$isAnonymous()) {
          return $q.reject(Access.UNAUTHORIZED);
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    isAnonymous: function () {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$isAnonymous()) {
          return Access.OK;
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    isAuthenticated: function () {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$isAuthenticated()) {
          return Access.OK;
        } else {
          return $q.reject(Access.UNAUTHORIZED);
        }
      });
    }

  };

  return Access;

}])

UserProfile copies the current user properties, and implement the $hasRole, $hasAnyRole, $isAnonymous and $isAuthenticated methods logic (plus a $refresh method, explained later):

.factory("UserProfile", ["Auth", function (Auth) {

  var userProfile = {};

  var clearUserProfile = function () {
    for (var prop in userProfile) {
      if (userProfile.hasOwnProperty(prop)) {
        delete userProfile[prop];
      }
    }
  };

  var fetchUserProfile = function () {
    return Auth.getProfile().then(function (response) {
      clearUserProfile();
      return angular.extend(userProfile, response.data, {

        $refresh: fetchUserProfile,

        $hasRole: function (role) {
          return userProfile.roles.indexOf(role) >= 0;
        },

        $hasAnyRole: function (roles) {
          return !!userProfile.roles.filter(function (role) {
            return roles.indexOf(role) >= 0;
          }).length;
        },

        $isAnonymous: function () {
          return userProfile.anonymous;
        },

        $isAuthenticated: function () {
          return !userProfile.anonymous;
        }

      });
    });
  };

  return fetchUserProfile();

}])

Auth is in charge of requesting the server, to know the user profile (linked to an access token attached to the request for example):

.service("Auth", ["$http", function ($http) {

  this.getProfile = function () {
    return $http.get("api/auth");
  };

}])

The server is expected to return such a JSON object when requesting GET api/auth:

{
  "name": "John Doe", // plus any other user information
  "roles": ["ROLE_ADMIN", "ROLE_USER"], // or any other role (or no role at all, i.e. an empty array)
  "anonymous": false // or true
}

Finally, when Access rejects a promise, if using ui.router, the $stateChangeError event will be fired:

.run(["$rootScope", "Access", "$state", "$log", function ($rootScope, Access, $state, $log) {

  $rootScope.$on("$stateChangeError", function (event, toState, toParams, fromState, fromParams, error) {
    switch (error) {

    case Access.UNAUTHORIZED:
      $state.go("signIn");
      break;

    case Access.FORBIDDEN:
      $state.go("forbidden");
      break;

    default:
      $log.warn("$stateChangeError event catched");
      break;

    }
  });

}])

If using ngRoute, the $routeChangeError event will be fired:

.run(["$rootScope", "Access", "$location", "$log", function ($rootScope, Access, $location, $log) {

  $rootScope.$on("$routeChangeError", function (event, current, previous, rejection) {
    switch (rejection) {

    case Access.UNAUTHORIZED:
      $location.path("/signin");
      break;

    case Access.FORBIDDEN:
      $location.path("/forbidden");
      break;

    default:
      $log.warn("$stateChangeError event catched");
      break;

    }
  });

}])

The user profile can also be accessed in the controllers:

.state("home", {
  /* ... */
  controller: "HomeController",
  resolve: {
    userProfile: "UserProfile"
  }
})

UserProfile then contains the properties returned by the server when requesting GET api/auth:

.controller("HomeController", ["$scope", "userProfile", function ($scope, userProfile) {

  $scope.title = "Hello " + userProfile.name; // "Hello John Doe" in the example

}])

UserProfile needs to be refreshed when a user signs in or out, so that Access can handle the routes with the new user profile. You can either reload the whole page, or call UserProfile.$refresh(). Example when signing in:

.service("Auth", ["$http", function ($http) {

  /* ... */

  this.signIn = function (credentials) {
    return $http.post("api/auth", credentials).then(function (response) {
      // authentication succeeded, store the response access token somewhere (if any)
    });
  };

}])

.state("signIn", {
  /* ... */
  controller: "SignInController",
  resolve: {
    /* ... */
    userProfile: "UserProfile"
  }
})

.controller("SignInController", ["$scope", "$state", "Auth", "userProfile", function ($scope, $state, Auth, userProfile) {

  $scope.signIn = function () {
    Auth.signIn($scope.credentials).then(function () {
      // user successfully authenticated, refresh UserProfile
      return userProfile.$refresh();
    }).then(function () {
      // UserProfile is refreshed, redirect user somewhere
      $state.go("home");
    });
  };

}])

For static text:

• Generate an image with all words used on your PC (For example with GIMP).
• Load this as a texture and use it as material for a plane.

For long text that needs to be updated once in a while:

• Let android draw on a bitmap canvas (JVitela's solution).
• Load this as material for a plane.
• Use different texture coordinates for each word.

For a number (formatted 00.0):

• Generate an image with all numbers and a dot.
• Load this as material for a plane.
• Use below shader.

• In your onDraw event only update the value variable sent to the shader.

  } else {

  }
  gl_FragColor = fragColor;

Above code works for a texture atlas where numbers start from 0 at the 7th column of the 2nd row of the font atlas (texture).

            else return new List<string>() { };
        }

        public IEnumerable<Students> getlist(int id, string name)

        {
            if (id == 1 && name == "kim")
                return new List<string>() { "emgili", "hindi", "pun" };
            if (id == 2 && name == "aman")
                return new List<string>() { "math" };
            else return new List<string>() { "no data" };
        }
    }
}

Use imageWithData: method, which gets translated to Swift as UIImage(data:)

let image : UIImage = UIImage(data: imageData)

Most browsers have a native JSON object these days, which includes parse and stringify methods. So just try JSON.stringify({}) and see if you get "{}". You can even pass in parameters to filter out keys or to do pretty-printing, e.g. JSON.stringify({a:1,b:2}, null, 2) puts a newline and 2 spaces in front of each key.

JSON.stringify({a:1,b:2}, null, 2)

gives

"{\n  \"a\": 1,\n  \"b\": 2\n}"

which prints as

{
  "a": 1,
  "b": 2
}

As for the messing around part of your question, use the second parameter. From http://www.javascriptkit.com/jsref/json.shtml :

The replacer parameter can either be a function or an array of String/Numbers. It steps through each member within the JSON object to let you decide what value each member should be changed to. As a function it can return:

• A number, string, or Boolean, which replaces the property's original value with the returned one.
• An object, which is serialized then returned. Object methods or functions are not allowed, and are removed instead.
• Null, which causes the property to be removed.

As an array, the values defined inside it corresponds to the names of the properties inside the JSON object that should be retained when converted into a JSON object.

The examples below refer to the following HTML snippet:

<div id="test">
   Warning: This element contains <code>code</code> and <strong>strong language</strong>.
</div>

The node will be referenced by the following JavaScript:

var x = document.getElementById('test');

element.innerHTML

Sets or gets the HTML syntax describing the element's descendants

x.innerHTML
// => "
// =>   Warning: This element contains <code>code</code> and <strong>strong language</strong>.
// => "

This is part of the W3C's DOM Parsing and Serialization Specification. Note it's a property of Element objects.

node.innerText

Sets or gets the text between the start and end tags of the object

x.innerText
// => "Warning: This element contains code and strong language."

• innerText was introduced by Microsoft and was for a while unsupported by Firefox. In August of 2016, innerText was adopted by the WHATWG and was added to Firefox in v45.
• innerText gives you a style-aware, representation of the text that tries to match what's rendered in by the browser this means:
  • innerText applies text-transform and white-space rules
  • innerText trims white space between lines and adds line breaks between items
  • innerText will not return text for invisible items
• innerText will return textContent for elements that are never rendered like <style /> and `
• Property of Node elements

node.textContent

Gets or sets the text content of a node and its descendants.

x.textContent
// => "
// =>   Warning: This element contains code and strong language.
// => "

While this is a W3C standard, it is not supported by IE < 9.

• Is not aware of styling and will therefore return content hidden by CSS
• Does not trigger a reflow (therefore more performant)
• Property of Node elements

node.value

This one depends on the element that you've targeted. For the above example, x returns an HTMLDivElement object, which does not have a value property defined.

x.value // => null

Input tags (<input />), for example, do define a value property, which refers to the "current value in the control".

<input id="example-input" type="text" value="default" />
<script>
  document.getElementById('example-input').value //=> "default"
  // User changes input to "something"
  document.getElementById('example-input').value //=> "something"
</script>

From the docs:

Note: for certain input types the returned value might not match the value the user has entered. For example, if the user enters a non-numeric value into an <input type="number">, the returned value might be an empty string instead.

Sample Script

Here's an example which shows the output for the HTML presented above:

var properties = ['innerHTML', 'innerText', 'textContent', 'value'];_x000D_
_x000D_
// Writes to textarea#output and console_x000D_
function log(obj) {_x000D_
  console.log(obj);_x000D_
  var currValue = document.getElementById('output').value;_x000D_
  document.getElementById('output').value = (currValue ? currValue + '\n' : '') + obj; _x000D_
}_x000D_
_x000D_
// Logs property as [propName]value[/propertyName]_x000D_
function logProperty(obj, property) {_x000D_
  var value = obj[property];_x000D_
  log('[' + property + ']'  +  value + '[/' + property + ']');_x000D_
}_x000D_
_x000D_
// Main_x000D_
log('=============== ' + properties.join(' ') + ' ===============');_x000D_
for (var i = 0; i < properties.length; i++) {_x000D_
  logProperty(document.getElementById('test'), properties[i]);_x000D_
}

<div id="test">_x000D_
  Warning: This element contains <code>code</code> and <strong>strong language</strong>._x000D_
</div>_x000D_
<textarea id="output" rows="12" cols="80" style="font-family: monospace;"></textarea>

just set data-trigger="focus click"

I am sure there must be a way of doing this without writing my own CSS, its crazy I have to overwrite the margin and padding, all I wanted was a 2 column grid.

.row-offset-0 {
    margin-left: 0;
    margin-right: 0;
}
.row-offset-0 > * {
    padding-left: 0;
    padding-right: 0;
}

"+" not "."

But be careful with String concatenation. Here's a link introducing some thoughts from IBM DeveloperWorks.

It is supported by Chrome. It's not supposed to be used for validation, but for type hinting the OS. If you have an accept="image/jpeg" attribute in a file upload the OS can only show files of the suggested type.

you should use action instead of actionListener:

<h:commandLink id="close" action="#{bean.close}" value="Close" immediate="true" 
                                   />

and in close method you right something like:

public String close() {
   return "index?faces-redirect=true";
}

where index is one of your pages(index.xhtml)

Of course, all this staff should be written in our original page, not in the intermediate. And inside the close() method you can use the parameters to dynamically choose where to redirect.

What about something like :

angle = angle % 360;

class Program
{
        static void Main(string[] args)
        {
            char[] originalString = "This string contains the unicode character Pi(p)".ToCharArray();
            StringBuilder asAscii = new StringBuilder(); // store final ascii string and Unicode points
            foreach (char c in originalString)
            {
                // test if char is ascii, otherwise convert to Unicode Code Point
                int cint = Convert.ToInt32(c);
                if (cint <= 127 && cint >= 0)
                    asAscii.Append(c);
                else
                    asAscii.Append(String.Format("\\u{0:x4} ", cint).Trim());
            }
            Console.WriteLine("Final string: {0}", asAscii);
            Console.ReadKey();
        }
}

All non-ASCII chars are converted to their Unicode Code Point representation and appended to the final string.

I was stuck in this issue today and found this code is working fine for me

$('#content').on('mousewheel', function(event) {
    //console.log(event.deltaX, event.deltaY, event.deltaFactor);
    if(event.deltaY > 0) {
      console.log('scroll up');
    } else {
      console.log('scroll down');
    }
});

Check the spelling, mine was 'com.android.aplication'

with pages as (
    SELECT object_id, SUM (reserved_page_count) as reserved_pages, SUM (used_page_count) as used_pages,
            SUM (case 
                    when (index_id < 2) then (in_row_data_page_count + lob_used_page_count + row_overflow_used_page_count)
                    else lob_used_page_count + row_overflow_used_page_count
                 end) as pages
    FROM sys.dm_db_partition_stats
    group by object_id

    WHERE it.internal_type IN (202,204,211,212,213,214,215,216) AND p.object_id = it.object_id
    group by p.object_id
)
SELECT object_schema_name(p.object_id) + '.' + object_name(p.object_id) as TableName, (p.reserved_pages + isnull(e.reserved_pages, 0)) * 8 as reserved_kb,
        pages * 8 as data_kb,
        (CASE WHEN p.used_pages + isnull(e.used_pages, 0) > pages THEN (p.used_pages + isnull(e.used_pages, 0) - pages) ELSE 0 END) * 8 as index_kb,
        (CASE WHEN p.reserved_pages + isnull(e.reserved_pages, 0) > p.used_pages + isnull(e.used_pages, 0) THEN (p.reserved_pages + isnull(e.reserved_pages, 0) - p.used_pages + isnull(e.used_pages, 0)) else 0 end) * 8 as unused_kb
from pages p
left outer join extra e on p.object_id = e.object_id

Takes into account internal tables, such as those used for XML storage.

Edit: If you divide the data_kb and index_kb values by 1024.0, you will get the numbers you see in the GUI.

A simple solution:

Encode the image as a jpeg and look for a substantial change in filesize.

I've implemented something similar with video thumbnails, and had a lot of success and scalability.

Here is the detailed answer to the question:

Pass data into the HTTP header from the Angular side (Please note I am using Angular4.0+ in the application).

There is more than one way we can pass data into the headers. The syntax is different but all means the same.

// Option 1 
 const httpOptions = {
   headers: new HttpHeaders({
     'Authorization': 'my-auth-token',
     'ID': emp.UserID,
   })
 };


// Option 2

let httpHeaders = new HttpHeaders();
httpHeaders = httpHeaders.append('Authorization', 'my-auth-token');
httpHeaders = httpHeaders.append('ID', '001');
httpHeaders.set('Content-Type', 'application/json');    

let options = {headers:httpHeaders};


// Option 1
   return this.http.post(this.url + 'testMethod', body,httpOptions)

// Option 2
   return this.http.post(this.url + 'testMethod', body,options)

In the call you can find the field passed as a header as shown in the image below :

Still, if you are facing the issues like.. (You may need to change the backend/WebAPI side)

• Response to preflight request doesn't pass access control check: No ''Access-Control-Allow-Origin'' header is present on the requested resource. Origin ''http://localhost:4200'' is therefore not allowed access

• Response for preflight does not have HTTP ok status.

A constant value cannot change. A static variable exists to a function, or class, rather than an instance or object.

These two concepts are not mutually exclusive, and can be used together.

What you can do is store the router IP of your user and also the forwarded IP and try to make it reliable using both the IPs [External Public and Internal Private]. But again after some days client may be assigned new internal IP from router but it will be more reliable.

There is no ArrayList in javascript.

There is however Array^{ECMA 5.1} which has similar functionality to an "ArrayList". The majority of this answer is taken verbatim from the HTML rendering of Ecma-262 Edition 5.1, The ECMAScript Language Specification.

Defined arrays have the following methods available:

• .toString ( )
• .toLocaleString ( )
• .concat ( [ item1 [ , item2 [ , … ] ] ] )

  When the concat method is called with zero or more arguments item1, item2, etc., it returns an array containing the array elements of the object followed by the array elements of each argument in order.

• .join (separator)

  The elements of the array are converted to Strings, and these Strings are then concatenated, separated by occurrences of the separator. If no separator is provided, a single comma is used as the separator.

• .pop ( )

  The last element of the array is removed from the array and returned.

• .push ( [ item1 [ , item2 [ , … ] ] ] )

  The arguments are appended to the end of the array, in the order in which they appear. The new length of the array is returned as the result of the call."

• .reverse ( )

  The elements of the array are rearranged so as to reverse their order. The object is returned as the result of the call.

• .shift ( )

  The first element of the array is removed from the array and returned."

• .slice (start, end)

  The slice method takes two arguments, start and end, and returns an array containing the elements of the array from element start up to, but not including, element end (or through the end of the array if end is undefined).

• .sort (comparefn)

  The elements of this array are sorted. The sort is not necessarily stable (that is, elements that compare equal do not necessarily remain in their original order). If comparefn is not undefined, it should be a function that accepts two arguments x and y and returns a negative value if x < y, zero if x = y, or a positive value if x > y.

• .splice (start, deleteCount [ , item1 [ , item2 [ , … ] ] ] )

  When the splice method is called with two or more arguments start, deleteCount and (optionally) item1, item2, etc., the deleteCount elements of the array starting at array index start are replaced by the arguments item1, item2, etc. An Array object containing the deleted elements (if any) is returned.

• .unshift ( [ item1 [ , item2 [ , … ] ] ] )

  The arguments are prepended to the start of the array, such that their order within the array is the same as the order in which they appear in the argument list.

• .indexOf ( searchElement [ , fromIndex ] )

  indexOf compares searchElement to the elements of the array, in ascending order, using the internal Strict Equality Comparison Algorithm (11.9.6), and if found at one or more positions, returns the index of the first such position; otherwise, -1 is returned.

• .lastIndexOf ( searchElement [ , fromIndex ] )

  lastIndexOf compares searchElement to the elements of the array in descending order using the internal Strict Equality Comparison Algorithm (11.9.6), and if found at one or more positions, returns the index of the last such position; otherwise, -1 is returned.

• .every ( callbackfn [ , thisArg ] )

  callbackfn should be a function that accepts three arguments and returns a value that is coercible to the Boolean value true or false. every calls callbackfn once for each element present in the array, in ascending order, until it finds one where callbackfn returns false. If such an element is found, every immediately returns false. Otherwise, if callbackfn returned true for all elements, every will return true.

• .some ( callbackfn [ , thisArg ] )

  callbackfn should be a function that accepts three arguments and returns a value that is coercible to the Boolean value true or false. some calls callbackfn once for each element present in the array, in ascending order, until it finds one where callbackfn returns true. If such an element is found, some immediately returns true. Otherwise, some returns false.

• .forEach ( callbackfn [ , thisArg ] )

  callbackfn should be a function that accepts three arguments. forEach calls callbackfn once for each element present in the array, in ascending order.

• .map ( callbackfn [ , thisArg ] )

  callbackfn should be a function that accepts three arguments. map calls callbackfn once for each element in the array, in ascending order, and constructs a new Array from the results.

• .filter ( callbackfn [ , thisArg ] )

  callbackfn should be a function that accepts three arguments and returns a value that is coercible to the Boolean value true or false. filter calls callbackfn once for each element in the array, in ascending order, and constructs a new array of all the values for which callbackfn returns true.

• .reduce ( callbackfn [ , initialValue ] )

  callbackfn should be a function that takes four arguments. reduce calls the callback, as a function, once for each element present in the array, in ascending order.

• .reduceRight ( callbackfn [ , initialValue ] )

  callbackfn should be a function that takes four arguments. reduceRight calls the callback, as a function, once for each element present in the array, in descending order.

and also the length property.

Try this:

/^(\/([^/]+\/)*)(.*)$/

It will leave the trailing slash on the path, though.

• Optional.map():

Takes every element and if the value exists, it is passed to the function:

Optional<T> optionalValue = ...;
Optional<Boolean> added = optionalValue.map(results::add);

Now added has one of three values: true or false wrapped into an Optional , if optionalValue was present, or an empty Optional otherwise.

If you don't need to process the result you can simply use ifPresent(), it doesn't have return value:

optionalValue.ifPresent(results::add); 

• Optional.flatMap():

Works similar to the same method of streams. Flattens out the stream of streams. With the difference that if the value is presented it is applied to function. Otherwise, an empty optional is returned.

You can use it for composing optional value functions calls.

Suppose we have methods:

public static Optional<Double> inverse(Double x) {
    return x == 0 ? Optional.empty() : Optional.of(1 / x);
}

public static Optional<Double> squareRoot(Double x) {
    return x < 0 ? Optional.empty() : Optional.of(Math.sqrt(x));
}

Then you can compute the square root of the inverse, like:

Optional<Double> result = inverse(-4.0).flatMap(MyMath::squareRoot);

or, if you prefer:

Optional<Double> result = Optional.of(-4.0).flatMap(MyMath::inverse).flatMap(MyMath::squareRoot);

If either the inverse() or the squareRoot() returns Optional.empty(), the result is empty.

    NSDate *todaysDate = [NSDate new];
NSDateFormatter *formatter = [NSDateFormatter new];
[formatter setDateFormat:@"MM-dd-yyyy HH:mm:ss"];
NSString *strDateTime = [formatter stringFromDate:todaysDate];

NSString *strFileName = [NSString stringWithFormat:@"/Users/Shared/Recording_%@.mov",strDateTime];
NSLog(@"filename:%@",strFileName);

Log will be : filename:/Users/Shared/Recording_06-28-2016 12:53:26.mov

I don't know a built-in function, but writing one like this shouldn't be too complicated.

def frange(x, y, jump):
  while x < y:
    yield x
    x += jump

As the comments mention, this could produce unpredictable results like:

>>> list(frange(0, 100, 0.1))[-1]
99.9999999999986

To get the expected result, you can use one of the other answers in this question, or as @Tadhg mentioned, you can use decimal.Decimal as the jump argument. Make sure to initialize it with a string rather than a float.

>>> import decimal
>>> list(frange(0, 100, decimal.Decimal('0.1')))[-1]
Decimal('99.9')

Or even:

import decimal

def drange(x, y, jump):
  while x < y:
    yield float(x)
    x += decimal.Decimal(jump)

And then:

>>> list(drange(0, 100, '0.1'))[-1]
99.9

Class Assertions in org.junit.jupiter.api

Use:

public static void assertArrayEquals(int[] expected,
                                     int[] actual)

An easier way to do this is using crop from ImageOps. You can feed the number of pixels you want to crop from each side.

from PIL import ImageOps

border = (0, 30, 0, 30) # left, up, right, bottom
ImageOps.crop(img, border)

You need to escape the " so that PHP doesn't recognise them as part of your PHP code. You do this by using the \ escape character.

So, your code would look like this:

echo
    "<div>
        <h3><a href=\"#\">First</a></h3>
        <div>Lorem ipsum dolor sit amet.</div>
    </div>
    <div>"

Well, this question appears on top of search results, so I believe we need code example here. Here's the Python code:

import cv2

def apply_mask(frame, mask):
    """Apply binary mask to frame, return in-place masked image."""
    return cv2.bitwise_and(frame, frame, mask=mask)

Mask and frame must be the same size, so pixels remain as-is where mask is 1 and are set to zero where mask pixel is 0.

And for C++ it's a little bit different:

cv::Mat inFrame; // Original (non-empty) image
cv::Mat mask; // Original (non-empty) mask

// ...

cv::Mat outFrame;  // Result output
inFrame.copyTo(outFrame, mask);

Petar Ivanov's answer to replace a character at a specific index in a string question

String are immutable in Java. You can't change them.

You need to create a new string with the character replaced.

String myName = "domanokz";
String newName = myName.substring(0,4)+'x'+myName.substring(5);

Or you can use a StringBuilder:

StringBuilder myName = new StringBuilder("domanokz");
myName.setCharAt(4, 'x');

System.out.println(myName);

Multiple folks have already pointed that

$ screen -ls

would list the screen sessions.

Here is another trick that may be useful to you.

If you add the following command as a last line in your .bashrc file on server xxx, then it will automatically reconnect to your screen session on login.

screen -d -r

Hope you find it useful.

Putting on my gravedigger hat...

The best way I've found to address this is at compile time. Since you're the one setting prefix anyway might as well tell the executable explicitly where to find its shared libraries. Unlike OpenSSL and other software packages, Python doesn't give you nice configure directives to handle alternate library paths (not everyone is root you know...) In the simplest case all you need is the following:

./configure --enable-shared \
            --prefix=/usr/local \
            LDFLAGS="-Wl,--rpath=/usr/local/lib"

Or if you prefer the non-linux version:

./configure --enable-shared \
            --prefix=/usr/local \
            LDFLAGS="-R/usr/local/lib"

The "rpath" flag tells python it has runtime libraries it needs in that particular path. You can take this idea further to handle dependencies installed to a different location than the standard system locations. For example, on my systems since I don't have root access and need to make almost completely self-contained Python installs, my configure line looks like this:

./configure --enable-shared \
            --with-system-ffi \
            --with-system-expat \
            --enable-unicode=ucs4 \
            --prefix=/apps/python-${PYTHON_VERSION} \
            LDFLAGS="-L/apps/python-${PYTHON_VERSION}/extlib/lib -Wl,--rpath=/apps/python-${PYTHON_VERSION}/lib -Wl,--rpath=/apps/python-${PYTHON_VERSION}/extlib/lib" \
            CPPFLAGS="-I/apps/python-${PYTHON_VERSION}/extlib/include"

In this case I am compiling the libraries that python uses (like ffi, readline, etc) into an extlib directory within the python directory tree itself. This way I can tar the python-${PYTHON_VERSION} directory and land it anywhere and it will "work" (provided you don't run into libc or libm conflicts). This also helps when trying to run multiple versions of Python on the same box, as you don't need to keep changing your LD_LIBRARY_PATH or worry about picking up the wrong version of the Python library.

Edit: Forgot to mention, the compile will complain if you don't set the PYTHONPATH environment variable to what you use as your prefix and fail to compile some modules, e.g., to extend the above example, set the PYTHONPATH to the prefix used in the above example with export PYTHONPATH=/apps/python-${PYTHON_VERSION}...

Could you use the SQLPATH environment variable to tell sqlplus where to look for the scripts you are trying to run? I believe you could use HOST to set SQLPATH in the script too.

There could potentially be problems if two scripts have the same name and both directories are in the SQLPATH.

I have this function...

var escapeURIparam = function(url) {
    if (encodeURIComponent) url = encodeURIComponent(url);
    else if (encodeURI) url = encodeURI(url);
    else url = escape(url);
    url = url.replace(/\+/g, '%2B'); // Force the replacement of "+"
    return url;
};

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

I had the same problem too. I used this code:

Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);

Using the ADM, add the images on the sdcard or anywhere.

And when you are in your vm and the selection screen shows up, browse using the top left dropdown seen in the image below.

in normal time, checkboxes return an on/off value.

you can verify it with this code:

<form action method="POST">
      <input type="checkbox" name="hello"/>
</form>

<?php
if(isset($_POST['hello'])) echo('<p>'.$_POST['hello'].'</p>');
?>

this will return

<p>off</p>

or

<p>on</p>

I have changed the four quotes to three (this is the number required for multiline quotes), added a closing bracket after "What would you like to do? " and changed input to raw_input.

You can do this: add oldvalue attribute to html element, add set oldvalue when user click. Then onchange event use oldvalue.

<input type="text" id="test" value ="ABS" onchange="onChangeTest(this)" onclick="setoldvalue(this)" oldvalue="">

<script>
function setoldvalue(element){
   element.setAttribute("oldvalue",this.value);
}

function onChangeTest(element){
   element.setAttribute("value",this.getAttribute("oldvalue"));
}
</script>

I was having problem in Windows 7 with PHP 5.4.0 in command line, using Xampp 1.8.1 server. This is what i did:

1. Rename php.ini-production to php.ini (in C:\xampp\php\ folder)
2. Edit php.ini and uncomment extension_dir=ext.
3. Also uncomment extension=php_openssl.dll.

After that it worked fine.

If we want to add custom HTTP headers to a POST request, we must pass them through a dictionary to the headers parameter.

Here is an example with a non-empty body and headers:

import requests
import json

url = 'https://somedomain.com'
body = {'name': 'Maryja'}
headers = {'content-type': 'application/json'}

r = requests.post(url, data=json.dumps(body), headers=headers)

Sometimes, patience is key.

I had the same problem with a java project with big node_modules / .m2 directories.
The indexing was very long so I paused it and it prevented me from using Run Configurations.

So I waited for the indexing to finish and only then I was able to run my main class.

If you need to know the Commit history only, So don't use much Meshed up and bulky plugins,

I will recommend you a Basic simple plugin like "Git Commits"

I use it too :

0 and 7 both stand for Sunday, you can use the one you want, so writing 0-6 or 1-7 has the same result.

Also, as suggested by @Henrik, it is possible to replace numbers by shortened name of days, such as MON, THU, etc:

0 - Sun      Sunday
1 - Mon      Monday
2 - Tue      Tuesday
3 - Wed      Wednesday
4 - Thu      Thursday
5 - Fri      Friday
6 - Sat      Saturday
7 - Sun      Sunday

Graphically:

 +---------- minute (0 - 59)
 ¦ +-------- hour (0 - 23)
 ¦ ¦ +------ day of month (1 - 31)
 ¦ ¦ ¦ +---- month (1 - 12)
 ¦ ¦ ¦ ¦ +-- day of week (0 - 6 => Sunday - Saturday, or
 ¦ ¦ ¦ ¦ ¦                1 - 7 => Monday - Sunday)
 ? ? ? ? ?
 * * * * * command to be executed

Finally, if you want to specify day by day, you can separate days with commas, for example SUN,MON,THU will exectute the command only on sundays, mondays on thursdays.

You can read further details in Wikipedia's article about Cron.

In EDIT 2:

while((line = bufferedReader.readLine()) != null)
{
  sb.append(line); //append the lines to the string
  sb.append('\n'); //append new line
} //end while

you are reading the text file, and appending a newline to it. Don't append newline, which will not show a newline in some simple-minded Windows editors like Notepad. Instead append the OS-specific line separator string using:

sb.append(System.lineSeparator()); (for Java 1.7 and 1.8) or sb.append(System.getProperty("line.separator")); (Java 1.6 and below)

Alternatively, later you can use String.replaceAll() to replace "\n" in the string built in the StringBuffer with the OS-specific newline character:

String updatedText = text.replaceAll("\n", System.lineSeparator())

but it would be more efficient to append it while you are building the string, than append '\n' and replace it later.

Finally, as a developer, if you are using notepad for viewing or editing files, you should drop it, as there are far more capable tools like Notepad++, or your favorite Java IDE.

cat /sys/class/net/ethX is by far the easiest method.

The interface has to be up though, else you will get an invalid argument error.

So first:

ifconfig ethX up

Then:

cat /sys/class/net/ethX

The rest of the job opening listing could provide context to provide a better guess at what "Advanced SQL" may encompass.

I disagree with comments and responses indicating that understanding JOIN and aggregate queries are "advanced" skills; many employers would consider this rather basic, I'm afraid. Here's a rough guess as what "Advanced" can mean.

There's been an "awful" lot of new stuff in the RDBMS domain, in the last few years!

The "Advanced SQL" requirement probably hints at knowledge and possibly proficiency in several of the new concepts such as:

• CTEs (Common Table Expressions)
• UDFs (User Defined Functions)
• Fulltext search extensions/integration
• performance tuning with new partitionning schemes, filtered indexes, sparse columns...)
• new data types (ex: GIS/spatial or hierarchical)
• XML support / integration
• LINQ
• and a few more... (BTW the above list is somewhat MSSQL-centric, but similar evolution is observed in most other DBMS platforms).

While keeping abreast of the pro (and cons) of the new features is an important task for any "advanced SQL" practitioner, the old "advanced fundamentals" are probably also considered part of the "advanced":

• triggers and stored procedures at large
• Cursors (when to use, how to avoid ...)
• design expertise: defining tables, what to index, type of indexes
• performance tuning expertise in general
• query optimization (reading query plans, knowing what's intrinsically slow etc.)
• Procedural SQL
• ...

Note: the above focuses on skills associated with programming/lead role. "Advanced SQL" could also refer to experience with administrative roles (Replication, backups, hardware layout, user management...). Come to think about it, a serious programmer should be somewhat familiar with such practices as well.

Edit: LuckyLindy posted a comment which I found quite insightful. It suggests that "Advanced" may effectively have a different purpose than implying a fair-to-expert level in most of the categories listed above...
I repeat this comment here to give it more visibility.

I think a lot of companies post Advanced SQL because they are tired of getting someone who says "I'm a SQL expert" and has trouble putting together a 3 table outer join. I post similar stuff in job postings and my expectation is simply that a candidate will not need to constantly come to me for help writing SQL. (comment by LuckyLindy)

Since you haven't initialized car yet so it has no existence in JVM(Java Virtual Machine) so you have to initialize it first.

For instance :

car = new String{"Porsche","Lamborghini"};

Now your code will run fine.

INPUT:

String car [];
car = new String{"Porsche","Lamborghini"};
System.out.println(car.length);

There is a trick to force all 3 compilers does compile time evaluation even in the debug configuration with disabled optimization:

This issue arises when your 64 bit os tries to install the Android SDK which in turns tries to install some 32 bit binaries and thus is the issue of compatibility.

Open an additional terminal and type

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6 

would help to install all the required binaries. After this, start the afresh the Android SDK installation process.

Since globals are module specific, you can add the following function to all imported modules, and then use it to:

• Add singular variables (in dictionary format) as globals for those
• Transfer your main module globals to it .

addglobals = lambda x: globals().update(x)

Then all you need to pass on current globals is:

import module

module.addglobals(globals())

<form enctype="multipart/form-data">
   <input name="file" type="file" />
   <input type="submit" value="Upload" />
</form>
<script>
$('input[type=file]').change(function(){
    var file = this.files[0];
    name = file.name;
    size = file.size;
    type = file.type;
    //your validation
});
</script>

You can also:

[UIView animateWithDuration:1.0
                 animations:^{ self.view.alpha = 1.1; /* Some fake chages */ }
                 completion:^(BOOL finished)
{
    NSLog(@"A second lapsed.");
}];

This case you have to fake some changes to some view to get the animation work. It is hacky indeed, but I love the block based stuff. Or wrap up @mcfedr answer below.

waitFor(1.0, ^
{
    NSLog(@"A second lapsed");
});

typedef void (^WaitCompletionBlock)();
void waitFor(NSTimeInterval duration, WaitCompletionBlock completion)
{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC),
                   dispatch_get_main_queue(), ^
    { completion(); });
}

For me such issue occur when I had multiple export statements in single .ts file...

I'm not sure why previous answers haven't suggested that the original poster set up a shell profile (bashrc, .tcshrc, etc.) that executed their commands automatically every time they log in on the server side.

The quest that brought me to this page for help was a bit different -- I wanted multiple PuTTY shortcuts for the same host that would execute different startup commands.

I came up with two solutions, both of which worked:

(background) I have a folder with a variety of PuTTY shortcuts, each with the "target" property in the shortcut tab looking something like:

"C:\Program Files (x86)\PuTTY\putty.exe" -load host01

with each load corresponding to a PuTTY profile I'd saved (with different hosts in the "Session" tab). (Mostly they only differ in color schemes -- I like to have each group of related tasks share a color scheme in the terminal window, with critical tasks, like logging in as root on a production system, performed only in distinctly colored windows.)

The folder's Windows properties are set to very clean and stripped down -- it functions as a small console with shortcut icons for each of my frequent remote PuTTY and RDP connections.

(solution 1) As mentioned in other answers the -m switch is used to configure a script on the Windows side to run, the -t switch is used to stay connected, but I found that it was order-sensitive if I wanted to get it to run without exiting

What I finally got to work after a lot of trial and error was:

(shortcut target field):

"C:\Program Files (x86)\PuTTY\putty.exe" -t -load "SSH Proxy" -m "C:\Users\[me]\Documents\hello-world-bash.txt"

where the file being executed looked like

echo "Hello, World!"
echo ""
export PUTTYVAR=PROXY
/usr/local/bin/bash

(no semicolons needed)

This runs the scripted command (in my case just printing "Hello, world" on the terminal) and sets a variable that my remote session can interact with.

Note for debugging: when you run PuTTY it loads the -m script, if you edit the script you need to re-launch PuTTY instead of just restarting the session.

(solution 2) This method feels a lot cleaner, as the brains are on the remote Unix side instead of the local Windows side:

From Putty master session (not "edit settings" from existing session) load a saved config and in the SSH tab set remote command to:

export PUTTYVAR=GREEN; bash -l

Then, in my .bashrc, I have a section that performs different actions based on that variable:

case ${PUTTYVAR} in
  "")
    echo "" 
    ;;
  "PROXY")
    # this is the session config with all the SSH tunnels defined in it
    echo "";
    echo "Special window just for holding tunnels open." ;
    echo "";
    PROMPT_COMMAND='echo -ne "\033]0;Proxy Session @master01\$\007"'
    alias temppass="ssh keyholder.example.com makeonetimepassword"
    alias | grep temppass
    ;;
  "GREEN")
    echo "";
    echo "It's not easy being green"
    ;;
  "GRAY")
    echo ""
    echo "The gray ghost"
    ;;
  *)
    echo "";
    echo "Unknown PUTTYVAR setting ${PUTTYVAR}"
    ;;
esac

(solution 3, untried)

It should also be possible to have bash skip my .bashrc and execute a different startup script, by putting this in the PuTTY SSH command field:

bash --rcfile .bashrc_variant -l 

Why not try to add a ScrollView to wrap whatever it is you want to scroll. Here is how I have done it, where I actually leave a header on top which does not scroll, while the dialog widgets (in particular the EditTexts) scroll when you open soft keypad.

<LinearLayout android:id="@+id/HeaderLayout" >
  <!-- Here add a header or whatever will not be scrolled. -->
</LinearLayout>
<ScrollView android:id="@+id/MainForm" >
  <!-- Here add your edittexts or whatever will scroll. -->
</ScrollView>

I would typically have a LinearLayout inside the ScrollView, but that is up to you. Also, setting Scrollbar style to outsideInset helps, at least on my devices.

And now a keys iterator for range-based for loop.

    keys_it         operator++(int               ) /* postfix */ { return it_++         ; }
    keys_it&        operator++(                  ) /*  prefix */ { ++it_; return *this  ; }
    const key_type& operator* (                  ) const         { return it_->first    ; }
    const key_type& operator->(                  ) const         { return it_->first    ; }
    keys_it         operator+ (difference_type v ) const         { return it_ + v       ; }
    bool            operator==(const keys_it& rhs) const         { return it_ == rhs.it_; }
    bool            operator!=(const keys_it& rhs) const         { return it_ != rhs.it_; }
};

template<typename C>
class keys_impl
{
    const C & c;
public:
    keys_impl(const C & container) : c(container) {}
    const keys_it<C> begin() const { return keys_it<C>(std::begin(c)); }
    const keys_it<C> end  () const { return keys_it<C>(std::end  (c)); }
};

template<typename C>
keys_impl<C> keys(const C & container) { return keys_impl<C>(container); }

Usage:

std::map<std::string,int> my_map;
// fill my_map
for (const std::string & k : keys(my_map))

Most of the answers for python 3 on this page are either outdated or incomplete.
To get the mime type of a file on python3 I normally use:

import mimetypes
mt = mimetypes.guess_type("file.ext")[0]

From Python docs:

mimetypes.guess_type(url, strict=True)

Guess the type of a file based on its filename, path or URL, given by url. URL can be a string or a path-like object.

The return value is a tuple (type, encoding) where type is None if the type can’t be guessed (missing or unknown suffix) or a string of the form 'type/subtype', usable for a MIME content-type header.

encoding is None for no encoding or the name of the program used to encode (e.g. compress or gzip). The encoding is suitable for use as a Content-Encoding header, not as a Content-Transfer-Encoding header. The mappings are table driven. Encoding suffixes are case sensitive; type suffixes are first tried case sensitively, then case insensitively.

The optional strict argument is a flag specifying whether the list of known MIME types is limited to only the official types registered with IANA. When strict is True (the default), only the IANA types are supported; when strict is False, some additional non-standard but commonly used MIME types are also recognized.

Changed in version 3.8: Added support for url being a path-like object.

That last one was pretty good. I'd just tweak it a bit:

my @arr;
my @uniqarr;

foreach my $var ( @arr ){
  if ( ! grep( /$var/, @uniqarr ) ){
     push( @uniqarr, $var );
  }
}

I think this is probably the most readable way to do it.

There is a problem with pylint, which I do not completely understood yet.

I have my scripts organized in different folders for each package I pull in from bower, plus my own script for my app. Since you are going to list the order of these scripts somewhere, why not just list them in your gulp file? For new developers on your project, it's nice that all your script end-points are listed here. You can do this with gulp-add-src:

gulpfile.js

var gulp = require('gulp'),
    less = require('gulp-less'),
    minifyCSS = require('gulp-minify-css'),
    uglify = require('gulp-uglify'),
    concat = require('gulp-concat'),
    addsrc = require('gulp-add-src'),
    sourcemaps = require('gulp-sourcemaps');

// CSS & Less
gulp.task('css', function(){
    gulp.src('less/all.less')
        .pipe(sourcemaps.init())
        .pipe(less())
        .pipe(minifyCSS())
        .pipe(sourcemaps.write('source-maps'))
        .pipe(gulp.dest('public/css'));
});

// JS
gulp.task('js', function() {
    gulp.src('resources/assets/bower/jquery/dist/jquery.js')
    .pipe(addsrc.append('resources/assets/bower/bootstrap/dist/js/bootstrap.js'))
    .pipe(addsrc.append('resources/assets/bower/blahblah/dist/js/blah.js'))
    .pipe(addsrc.append('resources/assets/js/my-script.js'))
    .pipe(sourcemaps.init())
    .pipe(concat('all.js'))
    .pipe(uglify())
    .pipe(sourcemaps.write('source-maps'))
    .pipe(gulp.dest('public/js'));
});

gulp.task('default',['css','js']);

Note: jQuery and Bootstrap added for demonstration purposes of order. Probably better to use CDNs for those since they are so widely used and browsers could have them cached from other sites already.

You have empty $_POST. If your web-server wants see data in json-format you need to read the raw input and then parse it with JSON decode.

You need something like that:

$json = file_get_contents('php://input');
$obj = json_decode($json);

Also you have wrong code for testing JSON-communication...

CURLOPT_POSTFIELDS tells curl to encode your parameters as application/x-www-form-urlencoded. You need JSON-string here.

UPDATE

Your php code for test page should be like that:

$data_string = json_encode($data);

$ch = curl_init('http://webservice.local/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);
$result = json_decode($result);
var_dump($result);

Also on your web-service page you should remove one of the lines header('Content-type: application/json');. It must be called only once.

int is an alias for System.Int32, as defined in this table: Built-In Types Table (C# Reference)

If you're trying to find the first count multiples of m, something like this would work:

def multiples(m, count):
    for i in range(count):
        print(i*m)

Alternatively, you could do this with range:

def multiples(m, count):
    for i in range(0,count*m,m):
        print(i)

Note that both of these start the multiples at 0 - if you wanted to instead start at m, you'd need to offset it by that much:

range(m,(count+1)*m,m)

How about tr {outline: thin solid black;}? Works for me on tr or tbody elements, and appears to be compatible with the most browsers, including IE 8+ but not before.

The other answers have covered the direct question well, but you may also be interested in using set -e. With that, any command that fails (outside of specific contexts like if tests) will cause the script to abort. For certain scripts, it's very useful.

Here is another construction which starts with the simplest number format and then, in a non-overlapping way, progressively adds more complex number formats:

Java regep:

(\d)|([1-9]\d+)|(\.\d+)|(\d\.\d*)|([1-9]\d+\.\d*)|([1-9]\d{0,2}(,\d{3})+(\.\d*)?)

As a Java String (note the extra \ needed to escape to \ and . since \ and . have special meaning in a regexp when on their own):

String myregexp="(\\d)|([1-9]\\d+)|(\\.\\d+)|(\\d\\.\\d*)|([1-9]\\d+\\.\\d*)|([1-9]\\d{0,2}(,\\d{3})+(\\.\\d*)?)";   

Explanation:

1. This regexp has the form A|B|C|D|E|F where A,B,C,D,E,F are themselves regexps that do not overlap. Generally, I find it easier to start with the simplest possible matches, A. If A misses matches you want, then create a B that is a minor modification of A and includes a bit more of what you want. Then, based on B, create a C that catches more, etc. I also find it easier to create regexps that don't overlap; it is easier to understand a regexp with 20 simple non-overlapping regexps connected with ORs rather than a few regexps with more complex matching. But, each to their own!

2. A is (\d) and matches exactly one of 0,1,2,3,4,5,6,7,8,9 which can't be simpler!

3. B is ([1-9]\d+) and only matches numbers with 2 or more digits, the first excluding 0 . B matches exactly one of 10,11,12,... B does not overlap A but is a small modification of A.

4. C is (.\d+) and only matches a decimal followed by one or more digits. C matches exactly one of .0 .1 .2 .3 .4 .5 .6 .7 .8 .9 .00 .01 .02 ... . .23000 ... C allows trailing eros on the right which I prefer: if this is measurement data, the number of trailing zeros indicates the level of precision. If you don't want the trailing zeros on the right, change (.\d+) to (.\d*[1-9]) but this also excludes .0 which I think should be allowed. C is also a small modification of A.

5. D is (\d.\d*) which is A plus decimals with trailing zeros on the right. D only matches a single digit, followed by a decimal, followed by zero or more digits. D matches 0. 0.0 0.1 0.2 ....0.01000...9. 9.0 9.1..0.0230000 .... 9.9999999999... If you want to exclude "0." then change D to (\d.\d+). If you want to exclude trailing zeros on the right, change D to (\d.\d*[1-9]) but this excludes 2.0 which I think should be included. D does not overlap A,B,or C.

6. E is ([1-9]\d+.\d*) which is B plus decimals with trailing zeros on the right. If you want to exclude "13.", for example, then change E to ([1-9]\d+.\d+). E does not overlap A,B,C or D. E matches 10. 10.0 10.0100 .... 99.9999999999... Trailing zeros can be handled as in 4. and 5.

7. F is ([1-9]\d{0,2}(,\d{3})+(.\d*)?) and only matches numbers with commas and possibly decimals allowing trailing zeros on the right. The first group ([1-9]\d{0,2}) matches a non-zero digit followed zero, one or two more digits. The second group (,\d{3})+ matches a 4 character group (a comma followed by exactly three digits) and this group can match one or more times (no matches means no commas!). Finally, (.\d*)? matches nothing, or matches . by itself, or matches a decimal . followed by any number of digits, possibly none. Again, to exclude things like "1,111.", change (.\d*) to (.\d+). Trailing zeros can be handled as in 4. or 5. F does not overlap A,B,C,D, or E. I couldn't think of an easier regexp for F.

Let me know if you are interested and I can edit above to handle the trailing zeros on the right as desired.

Here is what matches regexp and what does not:

To use a view, the user must have the appropriate privileges but only for the view itself, not its underlying objects. However, if access privileges for the underlying objects of the view are removed, then the user no longer has access. This behavior occurs because the security domain that is used when a user queries the view is that of the definer of the view. If the privileges on the underlying objects are revoked from the view's definer, then the view becomes invalid, and no one can use the view. Therefore, even if a user has been granted access to the view, the user may not be able to use the view if the definer's rights have been revoked from the view's underlying objects.

Pass the id and hold into a variable and pass the variable where ever you want.

var temp = $('select[name=ID Name]').val();

I had a similar problem and solved it using list...not sure if this will help or not

classes = list(unique_labels(y_true, y_pred))

You forgot to put z as an bind variable.

The following EXECUTE command runs a PL/SQL statement that references a stored procedure:

SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')

Note that the value returned by the stored procedure is being return into :Z

When you create more than one instance of MyClass , you will still only have only one instance of publicMethod in memory but in case of privilegedMethod you will end up creating lots of instances and staticMethod has no relationship with an object instance.

That's why prototypes save memory.

Also, if you change the parent object's properties, is the child's corresponding property hasn't been changed, it'll be updated.

A long rant on personal names

A personal name is either a Polynym (a name with multiple sortable components), a Mononym (a name with only one component), or a Pictonym (a name represented by a picture - this exists due to people like Prince).

A person can have multiple names, playing roles, such as LEGAL, MARITAL, MAIDEN, PREFERRED, SOBRIQUET, PSEUDONYM, etc. You might have business rules, such as "a person can only have one legal name at a time, but multiple pseudonyms at a time".

Some examples:

names: [
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"George",
    middle:"Herman",
    moniker:"Babe",
    surname:"Ruth",
    generation:"JUNIOR"
  },
  {
    type:"MONONYM",
    role:"SOBRIQUET",
    mononym:"The Bambino" /* mononyms can be more than one word, but only one component */
  },
  {
    type:"MONONYM",
    role:"SOBRIQUET",
    mononym:"The Sultan of Swat"
  }
]

or

names: [
  {
    type:"POLYNYM",
    role:"PREFERRED",
    given:"Malcolm",
    surname:"X"
  },
  {
    type:"POLYNYM",
    role:"BIRTH",
    given:"Malcolm",
    surname:"Little"
  },
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"Malik",
    surname:"El-Shabazz"
  }
]

or

names:[
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"Prince",
    middle:"Rogers",
    surname:"Nelson"
  },
  {
    type:"MONONYM",
    role:"SOBRIQUET",
    mononym:"Prince"
  },
  {
    type:"PICTONYM",
    role:"LEGAL",
    url:"http://upload.wikimedia.org/wikipedia/en/thumb/a/af/Prince_logo.svg/130px-Prince_logo.svg.png"
  }
]

or

names:[
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"Juan Pablo",
    surname:"Fernández de Calderón",
    secondarySurname:"García-Iglesias" /* hispanic people often have two surnames. it can be impolite to use the wrong one. Portuguese and Spaniards differ as to which surname is important */
  }
]

Given names, middle names, surnames can be multiple words such as "Billy Bob" Thornton, or Ralph "Vaughn Williams".

To add an image to left, right, top or bottom, you can use attributes like this:

android:drawableLeft
android:drawableRight
android:drawableTop
android:drawableBottom

The sample code is given above. You can also achieve this using relative layout.

If you can possibly help it, DO NOT USE .scrollHeight.

.scrollHeight does not yield the same kind of results in different browsers in certain circumstances (most prominently while scrolling).

For example:

<div id='outer' style='width:100px; height:350px; overflow-y:hidden;'>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
</div>

If you do

console.log($('#outer').scrollHeight);

you'll get 900px in Chrome, FireFox and Opera. That's great.

But, if you attach a wheelevent / wheel event to #outer, when you scroll it, Chrome will give you a constant value of 900px (correct) but FireFox and Opera will change their values as you scroll down (incorrect).

A very simple way to do this is like so (a bit of a cheat, really). (This example works while dynamically adding content to #outer as well):

$('#outer').css("height", "auto");
var outerContentsHeight = $('#outer').height();
$('#outer').css("height", "350px");

console.log(outerContentsHeight); //Should get 900px in these 3 browsers

The reason I pick these three browsers is because all three can disagree on the value of .scrollHeight in certain circumstances. I ran into this issue making my own scrollpanes. Hope this helps someone.

What about

string[] filesPNG = Directory.GetFiles(path, "*.png");
string[] filesJPG = Directory.GetFiles(path, "*.jpg");
string[] filesJPEG = Directory.GetFiles(path, "*.jpeg");

int totalArraySizeAll = filesPNG.Length + filesJPG.Length + filesJPEG.Length;
List<string> filesAll = new List<string>(totalArraySizeAll);
filesAll.AddRange(filesPNG);
filesAll.AddRange(filesJPG);
filesAll.AddRange(filesJPEG);

Before you return your model from the controller, set your ReturnDate property to DateTime.Now()

myModel.ReturnDate = DateTime.Now()

return View(myModel)

Your view is not the right place to set values on properties so the controller is the better place for this.

You could even have it so that the getter on ReturnDate returns the current date/time.

private DateTime _returnDate = DateTime.MinValue;
public DateTime ReturnDate{
   get{
     return (_returnDate == DateTime.MinValue)? DateTime.Now() : _returnDate;
   }
   set{_returnDate = value;}
}

If you're not too worried in accuracy after days, you can simply do the maths

function timeSince(when) { // this ignores months
    var obj = {};
    obj._milliseconds = (new Date()).valueOf() - when.valueOf();
    obj.milliseconds = obj._milliseconds % 1000;
    obj._seconds = (obj._milliseconds - obj.milliseconds) / 1000;
    obj.seconds = obj._seconds % 60;
    obj._minutes = (obj._seconds - obj.seconds) / 60;
    obj.minutes = obj._minutes % 60;
    obj._hours = (obj._minutes - obj.minutes) / 60;
    obj.hours = obj._hours % 24;
    obj._days = (obj._hours - obj.hours) / 24;
    obj.days = obj._days % 365;
    // finally
    obj.years = (obj._days - obj.days) / 365;
    return obj;
}

then timeSince(pastDate); and use the properties as you like.

Otherwise you can use .getUTC* to calculate it, but note it may be slightly slower to calculate

function timeSince(then) {
    var now = new Date(), obj = {};
    obj.milliseconds = now.getUTCMilliseconds() - then.getUTCMilliseconds();
    obj.seconds = now.getUTCSeconds() - then.getUTCSeconds();
    obj.minutes = now.getUTCMinutes() - then.getUTCMinutes();
    obj.hours = now.getUTCHours() - then.getUTCHours();
    obj.days = now.getUTCDate() - then.getUTCDate();
    obj.months = now.getUTCMonth() - then.getUTCMonth();
    obj.years = now.getUTCFullYear() - then.getUTCFullYear();
    // fix negatives
    if (obj.milliseconds < 0) --obj.seconds, obj.milliseconds = (obj.milliseconds + 1000) % 1000;
    if (obj.seconds < 0) --obj.minutes, obj.seconds = (obj.seconds + 60) % 60;
    if (obj.minutes < 0) --obj.hours, obj.minutes = (obj.minutes + 60) % 60;
    if (obj.hours < 0) --obj.days, obj.hours = (obj.hours + 24) % 24;
    if (obj.days < 0) { // months have different lengths
        --obj.months;
        now.setUTCMonth(now.getUTCMonth() + 1);
        now.setUTCDate(0);
        obj.days = (obj.days + now.getUTCDate()) % now.getUTCDate();
    }
    if (obj.months < 0)  --obj.years, obj.months = (obj.months + 12) % 12;
    return obj;
}

You really want to do this

flog.write("\nCompany Name: "+ pCompanyName.encode('utf-8'))

This is the "encode late" strategy described in this unicode presentation (slides 32 through 35).

Python 3:

user225312's answer is correct:

A. To count number of characters in str object, you can use len() function:

>>> print(len('please anwser my question'))
25

B. To get memory size in bytes allocated to store str object, you can use sys.getsizeof() function

>>> from sys import getsizeof
>>> print(getsizeof('please anwser my question'))
50

Python 2:

It gets complicated for Python 2.

A. The len() function in Python 2 returns count of bytes allocated to store encoded characters in a str object.

Sometimes it will be equal to character count:

>>> print(len('abc'))
3

But sometimes, it won't:

>>> print(len('???'))  # String contains Cyrillic symbols
6

That's because str can use variable-length encoding internally. So, to count characters in str you should know which encoding your str object is using. Then you can convert it to unicode object and get character count:

>>> print(len('???'.decode('utf8'))) #String contains Cyrillic symbols 
3

B. The sys.getsizeof() function does the same thing as in Python 3 - it returns count of bytes allocated to store the whole string object

>>> print(getsizeof('???'))
27
>>> print(getsizeof('???'.decode('utf8')))
32

what I'd call a hack, but given that you're only processing hour values, you can do

 hour=08
 echo $(( ${hour#0} +1 ))
 9
 hour=10 
 echo $(( ${hour#0} +1))
 11

with little risk.

IHTH.

This topic is well covered already but I wanted to add something more specific : I wanted to be sure that a certain value would be mapped to that color (not to any color).

It is not complicated but as it took me some time, it might help others not lossing as much time as I did :)

You can also look at the Date.getTime() API. That gives a long to which you can add your increment. Then create a new Date.

List<Date> dates = new ArrayList<Date>();
long interval = 1000 * 60 * 60; // 1 hour in millis
long endtime = ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
  dates.add(new Date(curTime));
  curTime += interval;
}

and maybe apache commons has something like this in DateUtils, or perhaps they have a CalendarUtils too :)

EDIT

including the start and enddate may not be possible if your interval is not perfect :)

To go up a directory in a link, use ... This means "go up one directory", so your link will look something like this:

<a href="../index.html">Home</a>

<html>
    <body>
        <input id="check1" type="checkbox" checked="" name="copyNewAddrToBilling">
    </body>
    <script language="javascript">
        document.getElementById("check1").checked = true;
        document.getElementById("check1").checked = false;
    </script>
</html>

I have added the language attribute to the script element, but it is unnecessary because all browsers use this as a default, but it leaves no doubt what this example is showing.

If you want to use javascript to access elements, it has a very limited set of GetElement* functions. So you are going to need to get into the habit of giving every element a UNIQUE id attribute.

for /d %%a in (*) do (ECHO zip -r -p "%%~na.zip" ".\%%a\*")

should work from within a batch.

Note that I've included an ECHO to simply SHOW the command that is proposed. You'd need to remove the ECHO keywor to EXECUTE the commands.

The limit of requests in .Net can be configured from two properties together:

First

• Web.Config/system.web/httpRuntime/maxRequestLength
• Unit of measurement: kilobytes
• Default value 4096 KB (4 MB)

Second

• Web.Config/system.webServer/security/requestFiltering/requestLimits/maxAllowedContentLength (in bytes)
• Unit of measurement: bytes
• Default value 30000000 bytes (28.6 MB)

If you're interested in preserving aspect ratios and doing so in pure CSS (given the aspect ratio) you can do something like below. The key is the padding-bottom on the ::content element that sizes the container element. This is sized relative to its parent's width, which is 100% by default. The ratio specified here has to match up with the ratio of the sizes on the canvas element.

As per W3C: DOM permits programs and scripts to dynamically access and update the content, structure and style of XML or HTML documents.

DOM is composed of:

• set of objects/elements
• a structure of how these objects/elements can be combined
• and an interface to access and modify them

You can mock datetime using this:

In the module sources.py:

import datetime


class ShowTime:
    def current_date():
        return datetime.date.today().strftime('%Y-%m-%d')

In your tests.py:

from unittest import TestCase, mock
import datetime


class TestShowTime(TestCase):
    def setUp(self) -> None:
        self.st = sources.ShowTime()
        super().setUp()

    @mock.patch('sources.datetime.date')
    def test_current_date(self, date_mock):
        date_mock.today.return_value = datetime.datetime(year=2019, month=10, day=1)
        current_date = self.st.current_date()
        self.assertEqual(current_date, '2019-10-01')

I also had this problem. I used information from link, mentioned above, and found quick solution. If you have different schema, lets say test, and create user utest, owner of schema test and among views in schema test you have view vTestView, based on tables from schema dbo, while selecting from it you'll get error mentioned above - no access to base objects. It was enough for me to execute statement

ALTER AUTHORIZATION ON test.vTestView TO dbo;

which means that I change an ownership of vTextView from schema it belongs to (test) to database user dbo, owner of schema dbo. After that without any other permissions required user utest will be able to access data from test.vTestView

For eg: you are using two activity, if you want to switch over from Activity A to Activity B

Simply give like this.

          Intent intent = new Intent(A.this, B.class);
         startActivity(intent);
         finish();

try to add this :

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSAllowsArbitraryLoadsInWebContent</key>
    <true/>
    <key>NSAllowsLocalNetworking</key>
    <true/>
</dict>

Since a factorial is simply degenerative multiplication from the number given down to 1, it would indeed be easier to just loop through the multiplication:

Math.factorial = function(n) {

  if (n === 0||n === 1) {

    return 1;

  } else {

    for(var i = n; i > 0; --i) { //always make sure to decrement the value BEFORE it's tacked onto the original as a product
      n *= i;
    }

    return n;

  }

}

From verify documentation:

If a certificate is found which is its own issuer it is assumed to be the root CA.

In other words, root CA needs to self signed for verify to work. This is why your second command didn't work. Try this instead:

openssl verify -CAfile RootCert.pem -untrusted Intermediate.pem UserCert.pem

It will verify your entire chain in a single command.

<script type="text/javascript">
window.setTimeout("location=('timeout_session.htm');",900000);

In the header of every page has been working for me during site tests(the site is not yet in production). The HTML page it falls to ends the session and just informs the user of the need to log in again. This seems an easier way than playing with PHP logic. I'd love some comments on the idea. Any traps I havent seen in it ?

Check out pyftpdlib from Giampaolo Rodola. It is one of the very best ftp servers out there for python. It's used in google's chromium (their browser) and bazaar (a version control system). It is the most complete implementation on Python for RFC-959 (aka: FTP server implementation spec).

To install:

pip3 install pyftpdlib

From the commandline:

python3 -m pyftpdlib

Alternatively 'my_server.py':

#!/usr/bin/env python3

from pyftpdlib import servers
from pyftpdlib.handlers import FTPHandler
address = ("0.0.0.0", 21)  # listen on every IP on my machine on port 21
server = servers.FTPServer(address, FTPHandler)
server.serve_forever()

There's more examples on the website if you want something more complicated.

To get a list of command line options:

python3 -m pyftpdlib --help

Note, if you want to override or use a standard ftp port, you'll need admin privileges (e.g. sudo).

may be not the best python, but for string lists like ['1','1.0','2.0','2', '1.1', '1.10', '1.11', '1.2','7','3','5']with the expected target ['1', '1.0', '1.1', '1.2', '1.10', '1.11', '2', '2.0', '3', '5', '7'] helped me...

unsortedList = ['1','1.0','2.0','2', '1.1', '1.10', '1.11', '1.2','7','3','5']
sortedList = []
sortDict = {}
sortVal = []
#set zero correct (integer): examp: 1.000 will be 1 and breaks the order
zero = "000"
for i in sorted(unsortedList):
  x = i.split(".")
  if x[0] in sortDict:
    if len(x) > 1:
        sortVal.append(x[1])
    else:
        sortVal.append(zero)
    sortDict[x[0]] = sorted(sortVal, key = int)
  else:
    sortVal = []
    if len(x) > 1:
        sortVal.append(x[1])
    else:
        sortVal.append(zero)
    sortDict[x[0]] = sortVal
for key in sortDict:
  for val in sortDict[key]:
    if val == zero:
       sortedList.append(str(key))
    else:
       sortedList.append(str(key) + "." + str(val))
print(sortedList)

I've used this in the past, since we typically use razor syntax for coding

@using (Html.BeginForm("actionName", "controllerName", FormMethod.Post, new { target = "_blank" }))

{

// add hidden and form filed here

}

$("a.save, #country") 

will select both "a.save" class and "country" id.

In a batch file (Windows 7 and above) I found this method most reliable

Call :logging >"C:\Temp\NAME_Your_Log_File.txt" 2>&1
:logging
TITLE "Logging Commands"
ECHO "Read this output in your log file"
ECHO ..
Prompt $_
COLOR 0F

Obviously, use whatever commands you want and the output will be directed to the text file. Using this method is reliable HOWEVER there is NO output on the screen.

The following is needed:

• MS Online Services Assistant needs to be downloaded and installed.

Making more general the @showdev answer.

var getObjectByValue = function (array, key, value) {
    return array.filter(function (object) {
        return object[key] === value;
    });
};

Example:

getObjectByValue(data, "code", "DZ" );

I'm assuming you figured this out already but:

Technical Reference for Log Files in Configuration Manager

That's a list of client-side logs and what they do. They are located in Windows\CCM\Logs

AppEnforce.log will show you the actual command-line executed and the resulting exit code for each Deployment Type (only for the new style ConfigMgr Applications)

This is my go-to for troubleshooting apps. Haven't really found any other logs that are exceedingly useful.

Make first char of string spannable while searching for char in list/recycler like

ravi and ajay

previously highlighting like this but i wanted to be like below

ravi and ajay OR ravi and ajay

for this I searched for word length if it is equal to 1 ,I separated main string into words and calculated word start position then I searched word starting with char.

 public static SpannableString colorString(int color, String text, String... wordsToColor) {
    SpannableString coloredString = new SpannableString(text);

    for (String word : wordsToColor) {

        Log.e("tokentoken", "-wrd len-" + word.length());
        if (word.length() !=1) {
            int startColorIndex = text.toLowerCase().indexOf(word.toLowerCase());
            int endColorIndex = startColorIndex + word.length();
            try {
                coloredString.setSpan(new ForegroundColorSpan(color), startColorIndex, endColorIndex,
                        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

            } catch (Exception e) {
                e.getMessage();
            }
        } else {
            int start = 0;

            for (String token : text.split("[\u00A0 \n]")) {
                if (token.length() > 0) {
                    start = text.indexOf(token, start);
                   // Log.e("tokentoken", "-token-" + token + "   --start--" + start);
                    char x = token.toLowerCase().charAt(0);
                    char w = word.toLowerCase().charAt(0);
                   // Log.e("tokentoken", "-w-" + w + "   --x--" + x);

                    if (x == w) {
                        // int startColorIndex = text.toLowerCase().indexOf(word.toLowerCase());
                        int endColorIndex = start + word.length();
                        try {
                            coloredString.setSpan(new ForegroundColorSpan(color), start, endColorIndex,
                                    Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

                        } catch (Exception e) {
                            e.getMessage();
                        }
                    }
                }
            }

        }

    }

    return coloredString;
}

Like @amalBit's answer, register a listener to global layout and calculate the difference of dectorView's visible bottom and its proposed bottom, if the difference is bigger than some value(guessed IME's height), we think IME is up:

    final EditText edit = (EditText) findViewById(R.id.edittext);
    edit.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            if (keyboardShown(edit.getRootView())) {
                Log.d("keyboard", "keyboard UP");
            } else {
                Log.d("keyboard", "keyboard Down");
            }
        }
    });

private boolean keyboardShown(View rootView) {

    final int softKeyboardHeight = 100;
    Rect r = new Rect();
    rootView.getWindowVisibleDisplayFrame(r);
    DisplayMetrics dm = rootView.getResources().getDisplayMetrics();
    int heightDiff = rootView.getBottom() - r.bottom;
    return heightDiff > softKeyboardHeight * dm.density;
}

the height threshold 100 is the guessed minimum height of IME.

This works for both adjustPan and adjustResize.

I believe you are looking for:

gethostbyaddress

Just pass it the localhost IP.

There is also a gethostbyname function, that is also usefull.

Here I got the error: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

Because you didn't pass a base64-encoded string. Look at your functions: both download and dataURItoBlob do expect a data URI for some reason; you however are passing a plain html markup string to download in your example.

Not only is HTML invalid as base64, you are calling .split(',')[1] on it which will yield undefined - and "undefined" is not a valid base64-encoded string either.

I don't know, but I read that I need to encode my string to base64

That doesn't make much sense to me. You want to encode it somehow, only to decode it then?

What should I call and how?

Change the interface of your download function back to where it received the filename and text arguments.

Notice that the BlobBuilder does not only support appending whole strings (so you don't need to create those ArrayBuffer things), but also is deprecated in favor of the Blob constructor.

Can I put a name on my saved file?

Yes. Don't use the Blob constructor, but the File constructor.

function download(filename, text) {
    try {
        var file = new File([text], filename, {type:"text/plain"});
    } catch(e) {
        // when File constructor is not supported
        file = new Blob([text], {type:"text/plain"});
    }
    var url  = window.URL.createObjectURL(file);
    …
}

download('test.html', "<html>" + document.documentElement.innerHTML + "</html>");

See JavaScript blob filename without link on what to do with that object url, just setting the current location to it doesn't work.

Minimal reproduction example with disassembly analysis

main.c

void myfunc(char *const src, int len) {
    int i;
    for (i = 0; i < len; ++i) {
        src[i] = 42;
    }
}

int main(void) {
    char arr[] = {'a', 'b', 'c', 'd'};
    int len = sizeof(arr);
    myfunc(arr, len + 1);
    return 0;
}

GitHub upstream.

Compile and run:

gcc -fstack-protector-all -g -O0 -std=c99 main.c
ulimit -c unlimited && rm -f core
./a.out

fails as desired:

*** stack smashing detected ***: terminated
Aborted (core dumped)

Tested on Ubuntu 20.04, GCC 10.2.0.

On Ubuntu 16.04, GCC 6.4.0, I could reproduce with -fstack-protector instead of -fstack-protector-all, but it stopped blowing up when I tested on GCC 10.2.0 as per Geng Jiawen's comment. man gcc clarifies that as suggested by the option name, the -all version adds checks more aggressively, and therefore presumably incurs a larger performance loss:

-fstack-protector

Emit extra code to check for buffer overflows, such as stack smashing attacks. This is done by adding a guard variable to functions with vulnerable objects. This includes functions that call "alloca", and functions with buffers larger than or equal to 8 bytes. The guards are initialized when a function is entered and then checked when the function exits. If a guard check fails, an error message is printed and the program exits. Only variables that are actually allocated on the stack are considered, optimized away variables or variables allocated in registers don't count.

-fstack-protector-all

Like -fstack-protector except that all functions are protected.

Disassembly

Now we look at the disassembly:

objdump -D a.out

Notice the handy comments automatically added by objdump's artificial intelligence module.

If you run this program multiple times through GDB, you will see that:

• the canary gets a different random value every time
• the last loop of myfunc is exactly what modifies the address of the canary

The canary randomized by setting it with %fs:0x28, which contains a random value as explained at:

• https://unix.stackexchange.com/questions/453749/what-sets-fs0x28-stack-canary
• Why does this memory address %fs:0x28 ( fs[0x28] ) have a random value?

Debug attempts

From now on, we modify the code:

    myfunc(arr, len + 1);

to be instead:

    myfunc(arr, len);
    myfunc(arr, len + 1); /* line 12 */
    myfunc(arr, len);

to be more interesting.

We will then try to see if we can pinpoint the culprit + 1 call with a method more automated than just reading and understanding the entire source code.

gcc -fsanitize=address to enable Google's Address Sanitizer (ASan)

If you recompile with this flag and run the program, it outputs:

#0 0x4008bf in myfunc /home/ciro/test/main.c:4
#1 0x40099b in main /home/ciro/test/main.c:12
#2 0x7fcd2e13d82f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x2082f)
#3 0x400798 in _start (/home/ciro/test/a.out+0x40079

followed by some more colored output.

This clearly pinpoints the problematic line 12.

The source code for this is at: https://github.com/google/sanitizers but as we saw from the example it is already upstreamed into GCC.

ASan can also detect other memory problems such as memory leaks: How to find memory leak in a C++ code/project?

Valgrind SGCheck

As mentioned by others, Valgrind is not good at solving this kind of problem.

It does have an experimental tool called SGCheck:

SGCheck is a tool for finding overruns of stack and global arrays. It works by using a heuristic approach derived from an observation about the likely forms of stack and global array accesses.

So I was not very surprised when it did not find the error:

valgrind --tool=exp-sgcheck ./a.out

The error message should look like this apparently: Valgrind missing error

GDB

An important observation is that if you run the program through GDB, or examine the core file after the fact:

gdb -nh -q a.out core

then, as we saw on the assembly, GDB should point you to the end of the function that did the canary check:

(gdb) bt
#0  0x00007f0f66e20428 in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:54
#1  0x00007f0f66e2202a in __GI_abort () at abort.c:89
#2  0x00007f0f66e627ea in __libc_message (do_abort=do_abort@entry=1, fmt=fmt@entry=0x7f0f66f7a49f "*** %s ***: %s terminated\n") at ../sysdeps/posix/libc_fatal.c:175
#3  0x00007f0f66f0415c in __GI___fortify_fail (msg=<optimized out>, msg@entry=0x7f0f66f7a481 "stack smashing detected") at fortify_fail.c:37
#4  0x00007f0f66f04100 in __stack_chk_fail () at stack_chk_fail.c:28
#5  0x00000000004005f6 in main () at main.c:15
(gdb) f 5
#5  0x00000000004005f6 in main () at main.c:15
15      }
(gdb)

And therefore the problem is likely in one of the calls that this function made.

Next we try to pinpoint the exact failing call by first single stepping up just after the canary is set:

  400581:       64 48 8b 04 25 28 00    mov    %fs:0x28,%rax
  400588:       00 00 
  40058a:       48 89 45 f8             mov    %rax,-0x8(%rbp)

and watching the address:

(gdb) p $rbp - 0x8
$1 = (void *) 0x7fffffffcf18
(gdb) watch 0x7fffffffcf18
Hardware watchpoint 2: *0x7fffffffcf18
(gdb) c
Continuing.

Hardware watchpoint 2: *0x7fffffffcf18

Old value = 1800814336
New value = 1800814378
myfunc (src=0x7fffffffcf14 "*****?Vk\266", <incomplete sequence \355\216>, len=5) at main.c:3
3           for (i = 0; i < len; ++i) {
(gdb) p len
$2 = 5
(gdb) p i
$3 = 4
(gdb) bt
#0  myfunc (src=0x7fffffffcf14 "*****?Vk\266", <incomplete sequence \355\216>, len=5) at main.c:3
#1  0x00000000004005cc in main () at main.c:12

Now, this does leaves us at the right offending instruction: len = 5 and i = 4, and in this particular case, did point us to the culprit line 12.

However, the backtrace is corrupted, and contains some trash. A correct backtrace would look like:

#0  myfunc (src=0x7fffffffcf14 "abcd", len=4) at main.c:3
#1  0x00000000004005b8 in main () at main.c:11

so maybe this could corrupt the stack and prevent you from seeing the trace.

Also, this method requires knowing what is the last call of the canary checking function otherwise you will have false positives, which will not always be feasible, unless you use reverse debugging.

Here's a very simple free open-source CsvExport class for C#. There's an ASP.NET MVC example at the bottom.

I struggled for half a day to get JSCH to work without using the System.in as the input stream to no avail. I tried Ganymed http://www.ganymed.ethz.ch/ssh2/ and had it going in 5 minutes. All the examples seem to be aimed at one usage of the app and none of the examples showed what i needed. Ganymed's example Basic.java Baaaboof Has everything i need.

On localhost you should consider context path.

function wsURL(path) {
    var protocol = (location.protocol === 'https:') ? 'wss://' : 'ws://';
    var url = protocol + location.host;
    if(location.hostname === 'localhost') {
        url += '/' + location.pathname.split('/')[1]; // add context path
    }
    return url + path;
}

this is the DOM element on which the event was hooked. this.id is its ID. No need to wrap it in a jQuery instance to get it, the id property reflects the attribute reliably on all browsers.

$("select").change(function() {    
    alert("Changed: " + this.id);
}

Live example

You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event object's target property:

$("#container").change(function(event) {
    alert("Field " + event.target.id + " changed");
});

Live example

(jQuery ensures that the change event bubbles, even on IE where it doesn't natively.)

You have to return a promise instead of a variable. So in your function just return:

return relationsManagerResource.GetParentId(nodeId)

And later resolve the returned promise. Or you can make another deferred and resolve theParentId with it.

To prevent text selection ONLY after a double click:

You could use MouseEvent#detail property. For mousedown or mouseup events, it is 1 plus the current click count.

document.addEventListener('mousedown', function (event) {
  if (event.detail > 1) {
    event.preventDefault();
    // of course, you still do not know what you prevent here...
    // You could also check event.ctrlKey/event.shiftKey/event.altKey
    // to not prevent something useful.
  }
}, false);

See https://developer.mozilla.org/en-US/docs/Web/API/UIEvent/detail

I had the same issue, luckily I found the below code

This is the command that you need to execute on the mirror:

git remote update

This is a useful article which graphically shows the explanation of the reset command.

https://git-scm.com/docs/git-reset

Reset --hard can be quite dangerous as it overwrites your working copy without checking, so if you haven't commited the file at all, it is gone.

As for Source tree, there is no way I know of to undo commits. It would most likely use reset under the covers anyway

Import datetime and timedelta:

>>> from datetime import datetime, timedelta
>>> str(datetime.now() + timedelta(hours=9))[11:19]
'01:41:44'

But the better way is:

>>> (datetime.now() + timedelta(hours=9)).strftime('%H:%M:%S')
'01:42:05'

You can refer strptime and strftime behavior to better understand how python processes dates and time field

Try this in your css:

.a {

}

This is likely caused by your application's connection pool; not an Oracle DBMS issue. Most connection pools have a validate statement that can execute before giving you the connection. In oracle you would want "Select 1 from dual".

The reason it started occurring after you restarted the server is that the connection pool was probably added without a restart and you are just now experiencing the use of the connection pool for the first time. What is the modification dates on your resource files that deal with database connections?

Validate Query example:

 <Resource name="jdbc/EmployeeDB" auth="Container" 
            validationQuery="Select 1 from dual" type="javax.sql.DataSource" username="dbusername" password="dbpassword"
            driverClassName="org.hsql.jdbcDriver" url="jdbc:HypersonicSQL:database"
            maxActive="8" maxIdle="4"/>

EDIT: In the case of Grails, there are similar configuration options for the grails pool. Example for Grails 1.2 (see release notes for Grails 1.2)

dataSource {
    pooled = true
    dbCreate = "update"
    url = "jdbc:mysql://localhost/yourDB"
    driverClassName = "com.mysql.jdbc.Driver"
    username = "yourUser"
    password = "yourPassword"
    properties {
        maxActive = 50
        maxIdle = 25
        minIdle = 5
        initialSize = 5
        minEvictableIdleTimeMillis = 60000
        timeBetweenEvictionRunsMillis = 60000
        maxWait = 10000     
    }   
}

There are several ways to do this:

InStr

You can use the InStr build-in function to test if a String contains a substring. InStr will either return the index of the first match, or 0. So you can test if a String begins with a substring by doing the following:

If InStr(1, "Hello World", "Hello W") = 1 Then
    MsgBox "Yep, this string begins with Hello W!"
End If

If InStr returns 1, then the String ("Hello World"), begins with the substring ("Hello W").

Like

You can also use the like comparison operator along with some basic pattern matching:

If "Hello World" Like "Hello W*" Then
    MsgBox "Yep, this string begins with Hello W!"
End If

In this, we use an asterisk (*) to test if the String begins with our substring.

I had the same problem and resolved it by changing the character set of the column. Even though your database has a default character set of utf-8 I think it's possible for database columns to have a different character set in MySQL. Here's the SQL QUERY I used:

    ALTER TABLE database.table MODIFY COLUMN col VARCHAR(255)
    CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;

Actually the best way to accomplish this is to write the javascript in a .php and use jquery in a separate file to use the Jquery get script file or jquery load use php include function in the doc where the javascript will live. Essentially this is how it will look.

Dynamic Javascript File in a .php file extension - Contains a mixture of php variables pre processed by the server and the javascript that needs these variables in scripts.

Static Js File - Using http://api.jquery.com/jquery.getscript/ or http://api.jquery.com/load/

In the main html page call the static file as a regular js file. Calling the static js file will force load the dynamic data from the server.

some file.php 1:

<?php
$somevar = "Some Dynamic Data";
?>

$('input').val(<?php echo $somevar?>);

or simply echo the script such as

echo "$('input').val(".$somevar.");";

File 2:somejsfile.js:

$("#result").load( "file.php" );

File 3 myhtml.html:

<script src="somejsfile.js"></script>

I believe this answer the question for many people looking to mix php and javascript. It would be nice to have that data process in the background then have the user have delays waiting for data. You could also bypass the second file and simply use php's include on the main html page, you would just have your javascript exposed on the main page. For performance that is up to you and how you want to handle all of that.

I"m guessing i'm getting this error because the string is trying to substring a Null value. But wouldn't the ".length() > 0" part eliminate that issue?

No, calling itemdescription.length() when itemdescription is null would not generate a StringIndexOutOfBoundsException, but rather a NullPointerException since you would essentially be trying to call a method on null.

As others have indicated, StringIndexOutOfBoundsException indicates that itemdescription is not at least 38 characters long. You probably want to handle both conditions (I assuming you want to truncate):

final String value;
if (itemdescription == null || itemdescription.length() <= 0) {
    value = "_";
} else if (itemdescription.length() <= 38) {
    value = itemdescription;
} else { 
    value = itemdescription.substring(0, 38);
}
pstmt2.setString(3, value);

Might be a good place for a utility function if you do that a lot...

FYI, I've got the same error from Chrome console. I thought my AJAX function causing it, but I uncommented my minified script from /javascripts/ajax-vanilla.min.js to /javascripts/ajax-vanilla.js. But in reality the source file was at /javascripts/src/ajax-vanilla.js. So in Chrome you getting bad MIME type error even if the file cannot be found. In this case, the error message is described as text/plain bad MIME type.

Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)

Basic squid conf

/etc/squid3/squid.conf instead of the super bloated default config file

auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

# Choose the port you want. Below we set it to default 3128.
http_port 3128

Please note the basic_ncsa_auth program instead of the old ncsa_auth

squid 2.x

For squid 2.x you need to edit /etc/squid/squid.conf file and place:

auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Setting up a user

sudo htpasswd -c /etc/squid3/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid3 restart

squid 2.x

sudo htpasswd -c /etc/squid/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid restart

htdigest vs htpasswd

For the many people that asked me: the 2 tools produce different file formats:

• htdigest stores the password in plain text.
• htpasswd stores the password hashed (various hashing algos are available)

Despite this difference in format basic_ncsa_auth will still be able to parse a password file generated with htdigest. Hence you can alternatively use:

sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like

Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.

On Ubuntu 14.04 htdigest and htpasswd are both available in the [apache2-utils][1] package.

MacOS

Similar as above applies, but file paths are different.

Install squid

brew install squid

Start squid service

brew services start squid

Squid config file is stored at /usr/local/etc/squid.conf.

Comment or remove following line:

http_access allow localnet

Then similar to linux config (but with updated paths) add this:

auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Note that path to basic_ncsa_auth may be different since it depends on installed version when using brew, you can verify this with ls /usr/local/Cellar/squid/. Also note that you should add the above just bellow the following section:

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

Now generate yourself a user:password basic auth credential (note: htpasswd and htdigest are also both available on MacOS)

htpasswd -c /usr/local/etc/squid_passwords username_you_like

Restart the squid service

brew services restart squid

Here is what I do. All of these instructions are based on my minimal experiences with working PACs, so YMMV.

Download your pac file via your pac URL. It's plain text and should be easy to open in a text editor.

Near the bottom, there's probably a section that says something like: return "PROXY w.x.y.z:a" where "w.x.y.z" is an ip address or username and "a" is a port number.

Write these down.

In a recent version of eclipse :

• Go to Window -> Preferences -> General -> Network Connections=
• Change the provider to "Manual"
• Select the "HTTP" line and click the edit button
• Add the IP address and port number above to the http line
• If you have to authenticate to use the proxy,
  • select "Requires Authentication"
  • type in your username. Note that if your authentication is on a Windows domain, you might have to prepend the domain name and a backslash (\) like: MYDOMAIN\MYUSERID
  • Type in your password
• Click OK
• Click Apply
• Click OK

At this point, you should be able to browse using the internal web browser (at least on http URLs).

Good luck.

Edit: Just so you know, it's WAY easier to use Nexus, one set of <mirror> tags and a single proxy setup (inside Nexus) to manage the proxy issues of Maven inside a firewall.

The dash is a special character in Bash as noted at http://tldp.org/LDP/abs/html/special-chars.html#DASHREF. So escaping this once just gets you past Bash, but Grep still has it's own meaning to dashes (by providing options).

So you really need to escape it twice (if you prefer not to use the other mentioned answers). The following will/should work

grep \\-X
grep '\-X'
grep "\-X"

One way to try out how Bash passes arguments to a script/program is to create a .sh script that just echos all the arguments. I use a script called echo-args.sh to play with from time to time, all it contains is:

echo $*

I invoke it as:

bash echo-args.sh \-X
bash echo-args.sh \\-X
bash echo-args.sh "\-X"

You get the idea.

What you want to do is get the absolute path of the script (available via ${BASH_SOURCE[0]}) and then use this to get the parent directory and cd to it at the beginning of the script.

#!/bin/bash
parent_path=$( cd "$(dirname "${BASH_SOURCE[0]}")" ; pwd -P )

cd "$parent_path"
cat ../some.text

This will make your shell script work independent of where you invoke it from. Each time you run it, it will be as if you were running ./cat.sh inside dir.

Note that this script only works if you're invoking the script directly (i.e. not via a symlink), otherwise the finding the current location of the script gets a little more tricky)

This examples shows how to realize the confirmed window close operation.

The window has a Window adapter which switches the default close operation to EXIT_ON_CLOSEor DO_NOTHING_ON_CLOSE dependent on your answer in the OptionDialog.

The method closeWindow of the ConfirmedCloseWindow fires a close window event and can be used anywhere i.e. as an action of an menu item

public class WindowConfirmedCloseAdapter extends WindowAdapter {

    public void windowClosing(WindowEvent e) {

        Object options[] = {"Yes", "No"};

        int close = JOptionPane.showOptionDialog(e.getComponent(),
                "Really want to close this application?\n", "Attention",
                JOptionPane.YES_NO_OPTION,
                JOptionPane.INFORMATION_MESSAGE,
                null,
                options,
                null);

        if(close == JOptionPane.YES_OPTION) {
           ((JFrame)e.getSource()).setDefaultCloseOperation(
                   JFrame.EXIT_ON_CLOSE);
        } else {
           ((JFrame)e.getSource()).setDefaultCloseOperation(
                   JFrame.DO_NOTHING_ON_CLOSE);
        }
    }
}

public class ConfirmedCloseWindow extends JFrame {

    public ConfirmedCloseWindow() {

        addWindowListener(new WindowConfirmedCloseAdapter());
    }

    private void closeWindow() {
        processWindowEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));
    }
}

1. Right-click on project
2. Go to properties => project factes
3. Click on runtime tab
4. Check the box of the server
5. Then ok

Close the eclipse and start the server you will able to see and run the project.

WinSCP works fine on Linux under Wine. I installed Wine and WinSCP and had no problems.

I discovered this after a lot of experimentation.

In the initialisation of your activity:

setOnLongClickListener(new View.OnLongClickListener() {
  public boolean onLongClick(View view) {
    activity.openContextMenu(view);  
    return true;  // avoid extra click events
  }
});
setOnTouch(new View.OnTouchListener(){
  public boolean onTouch(View v, MotionEvent e){
    switch(e.getAction & MotionEvent.ACTION_MASK){
      // do drag/gesture processing. 
    }
    // you MUST return false for ACTION_DOWN and ACTION_UP, for long click to work
    // you can return true for ACTION_MOVEs that you consume. 
    // DOWN/UP are needed by the long click timer.
    // if you want, you can consume the UP if you have made a drag - so that after 
    // a long drag, no long-click is generated.
    return false;
  }
});
setLongClickable(true);

Not to say other answers are not great for certain circumstances, but this is one snippet I always user from Google:

- (void)runSigninThenInvokeSelector:(SEL)signInDoneSel {


    if (signInDoneSel) {
        [self performSelector:signInDoneSel];
    }

}

set ViewController's Extended Edges in storyboard so that underTopBar property is unchecked.

My very simple solution (assuming you have only vertical orientation supported) is to redefine application window bounds for iOS versions below 7, in App delegate didFinishLaunchingWithOptions method:

CGRect screenBounds = [[UIScreen mainScreen] bounds];
if ([HMService getIOSVersion] < 7) {
    // handling statusBar (iOS6) by leaving top 20px for statusbar.
    screenBounds.origin.y = 20;
    self.window = [[UIWindow alloc] initWithFrame:screenBounds];
}
else {
    self.window = [[UIWindow alloc] initWithFrame:screenBounds];
}

Since ID is auto increment, you can also specify ID=NULL as,

LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename SET ID=NULL;

In general, if you are using white-space: nowrap; it is probably because you know which columns are going to contain content which wraps (or stretches the cell). For those columns, I generally wrap the cell's contents in a span with a specific class attribute and apply a specific width.

Example:

HTML:

<td><span class="description">My really long description</span></td>

CSS:

span.description {
    display: inline-block;
    overflow: hidden;
    white-space: nowrap;
    width: 150px;
}

<?php 
$dateTime = new DateTime('now', new DateTimeZone('Asia/Kolkata')); 
echo $dateTime->format("d/m/y  H:i A"); 
?>

You can use this to display the date like this

22/06/15 10:46 AM

At the moment you're calling ToUniversalTime() - just get rid of that:

private long ConvertToTimestamp(DateTime value)
{
    long epoch = (value.Ticks - 621355968000000000) / 10000000;
    return epoch;
}

Alternatively, and rather more readably IMO:

private static readonly DateTime Epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
...

private static long ConvertToTimestamp(DateTime value)
{
    TimeSpan elapsedTime = value - Epoch;
    return (long) elapsedTime.TotalSeconds;
}

EDIT: As noted in the comments, the Kind of the DateTime you pass in isn't taken into account when you perform subtraction. You should really pass in a value with a Kind of Utc for this to work. Unfortunately, DateTime is a bit broken in this respect - see my blog post (a rant about DateTime) for more details.

You might want to use my Noda Time date/time API instead which makes everything rather clearer, IMO.

SELECT DATEADD(day,-30,date) AS before30d 
FROM...

But it is strongly recommended to keep date in datetime column, not varchar.

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

    $headers = get_headers((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://" . $_SERVER[HTTP_HOST] . '/uploads/' . $MAIN['id'] . '.pdf');
    $fileExist = (stripos($headers[0], "200 OK") ? true : false);
    if ($fileExist) {
    ?>
    <a class="button" href="/uploads/<?= $MAIN['id'] ?>.pdf" download>???????</a> 
    <? }
    ?>

You could do this but it is hacky

.application-title {
   background:url("/path/to/image.png");
   /* set these dims according to your image size */
   width:500px;
   height:500px;
}

.application-title img {
   display:none;
}

Here is a working example:

That's exactly the difference between onPause and onStop events of the activity as described in the Activity class documentation.

If I understand you correctly, what you want to do is call finish() from your activity onStop to terminate it. See the attached image of the Activity Lifecycle Demo App. This is how it looks like when Activity B is launched from Activity A. The order of events is from bottom to top so you can see that Activity A onStop is called after Activity B onResume was already called.

In case a dialog is shown your activity is dimmed in the background and only onPause is called.

I had similar problem as Pietro,

I am on Window 10 and using "Git Bash". I tried to execute >>cmake -G "MinGW Makefiles", but I got the same error as Pietro.

Then, I tried >>cmake -G "MSYS Makefiles", but realized that I need to set my environment correctly.

Make sure set a path to C:\MinGW\msys\1.0\bin and check if you have gcc.exe there. If gcc.exe is not there then you have to run C:/MinGW/bin/mingw-get.exe and install gcc from MSYS.

After that it works fine for me

$("input[name='mygroup'][value='5']").attr("checked", true);

In JavaScript you can use template literals:

let value = 100;
console.log(`The size is ${ value }`);

Although many year ago, clsocket seems a really nice small cross-platform (Windows, Linux, Mac OSX): https://github.com/DFHack/clsocket

    // prepare json data
    let mapDict = [ "1":"First", "2":"Second"]

    let json = [ "title":"ABC" , "dict": mapDict ] as [String : Any]
    let jsonData : NSData = NSKeyedArchiver.archivedData(withRootObject: json) as NSData

    // create post request
    let url = NSURL(string: "http://httpbin.org/post")!
    let request = NSMutableURLRequest(url: url as URL)
    request.httpMethod = "POST"

    // insert json data to the request
    request.httpBody = jsonData as Data


    let task = URLSession.shared.dataTask(with: request as URLRequest){ data,response,error in
        if error != nil{
            return
        }
        do {
            let result = try JSONSerialization.jsonObject(with: data!, options: []) as? [String:AnyObject]

            print("Result",result!)

        } catch {
            print("Error -> \(error)")
        }
    }

    task.resume()

Open Terminal

cd to/the/program/location
ruby program.rb

or add #!/usr/bin/env ruby in the first of your program (script tell that this is executed using Ruby Interpreter)

Open Terminal

cd to/the/program/location
chmod 777 program.rb
./program.rb

Argh :D not the fastest

Process.Start("notepad C:\test.txt");

This can be done with setjmp/longjmp in C. P99 has a quite comfortable toolset for this that also is consistent with the new thread model of C11.

There is a secret pilot program which WhatsApp is working on with selected businesses

For some of my technical experiments, I was trying to figure out how beneficial and feasible it is to implement bots for different chat platforms in terms of market share and so possibilities of adaptation. Especially when you have bankruptly failed twice, it's important to validate ideas and fail more faster.

Popular chat platforms like Messenger, Slack, Skype etc. have happily (in the sense officially) provided APIs for bots to interact with, but WhatsApp has not yet provided any API.

However, since many years, a lot of activities has happened around this - struggle towards automated interaction with WhatsApp platform:

1. Bots App Bots App is interesting because it shows that something is really tried and tested.

2. Yowsup A project still actively developed to interact with WhatsApp platform.

3. Yallagenie Yallagenie claim that there is a demo bot which can be interacted with at +971 56 112 6652

4. Hubtype Hubtype is working towards having a bot platform for WhatsApp for business.

5. Fred Fred's task was to automate WhatsApp conversations, however since it was not officially supported by WhatsApp - it was shut down.

6. Oye Gennie A bot blocked by WhatsApp.

7. App/Website to WhatsApp We can use custom URL schemes and Android intent system to interact with WhatsApp but still NOT WhatsApp API.

8. Chat API daemon Probably created by inspecting the API calls in WhatsApp web version. NOT affiliated with WhatsApp.

9. WhatsBot Deactivated WhatsApp bot. Created during a hackathon.

10. No API claim WhatsApp co-founder clearly stated this in a conference that they did not had any plans for APIs for WhatsApp.

11. Bot Ware They probably are expecting WhatsApp to release their APIs for chat bot platforms.

12. Vixi They seems to be talking about how some platform which probably would work for WhatsApp. There is no clarity as such.

13. Unofficial API This API can shut off any time.

    And the number goes on...

Here's a function that'll do it:

def totuple(a):
    try:
        return tuple(totuple(i) for i in a)
    except TypeError:
        return a

And an example:

>>> array = numpy.array(((2,2),(2,-2)))
>>> totuple(array)
((2, 2), (2, -2))

The main issue is that you haven't supplied the first grep with any input. You will need to reorder your command something like

grep "word1" logs | grep "word2"

If you want to count the occurences, then put a '-c' on the second grep.

should avoid using unstable npm version.

I observed one thing that is npm version based issue, npm version 4.6.1 is the stable one but 5.x is unstable because package.json will be configured perfectly while creating with default template if it's a stable version and so we manually don't need to add that scripts.

I got the below issue on the npm 5 so I downgraded to npm 4.6.1 then its worked for me,

ERROR: npm 5 is not supported yet

It looks like you're using npm 5 which was recently released.

Create React Native App doesn't work with npm 5 yet, unfortunately. We recommend using npm 4 or yarn until some bugs are resolved.

You can follow the known issues with npm 5 at: https://github.com/npm/npm/issues/16991

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

Bass can do just this. Play from Byte[] in memory or a through file delegates where you return the data, so with that you can play as soon as you have enough data to start the playback..

static mySingleton *obj=nil;

@implementation mySingleton

-(id) init {
    if(obj != nil){     
        [self release];
        return obj;
    } else if(self = [super init]) {
        obj = self;
    }   
    return obj;
}

+(mySingleton*) getSharedInstance {
    @synchronized(self){
        if(obj == nil) {
            obj = [[mySingleton alloc] init];
        }
    }
    return obj;
}

- (id)retain {
    return self;
}

- (id)copy {
    return self;
}

- (unsigned)retainCount {
    return UINT_MAX;  // denotes an object that cannot be released
}

- (void)release {
    if(obj != self){
        [super release];
    }
    //do nothing
}

- (id)autorelease {
    return self;
}

-(void) dealloc {
    [super dealloc];
}
@end

You can use this code for generating has code for a given string.

int hash = 7;
for (int i = 0; i < strlen; i++) {
    hash = hash*31 + charAt(i);
}

I know that this isn't what you asked for but LINQPad is a really great tool to teach yourself LINQ (and it's free :o).

When time isn't critical, I have been using it for the last week or so instead or a query window in SQL Server and my LINQ skills are getting better and better.

It's also a nice little code snippet tool. Its only downside is that the free version doesn't have IntelliSense.
