Basically regular grammar is a subset of context free grammar,but we can not say Every Context free grammar is a regular grammar. Mainly context free grammar is ambiguous and regular grammar may be ambiguous.

Another way you can achieve a pause between animations is to apply a second animation that hides the element for the amount of delay you want. This has the benefit of allowing you to use a CSS easing function like you would normally.

.star {
  animation: shooting-star 1000ms ease-in-out infinite,
    delay-animation 2000ms linear infinite;
}

@keyframes shooting-star {
  0% {
    transform: translate(0, 0) rotate(45deg);
  }

  100% {
    transform: translate(300px, 300px) rotate(45deg);
  }
}

@keyframes delay-animation {
  0% {
    opacity: 1;
  }
  50% {
    opacity: 1;
  }
  50.01% {
    opacity: 0;
  }
  100% {
    opacity: 0;
  }
}

This only works if you want the delay to be a multiple of the animation duration. I used this to make a shower of shooting stars appear more random: https://codepen.io/ericdjohnson/pen/GRpOgVO

Use flock. It's new. It's better.

Now you don't have to write the code yourself. Check out more reasons here: https://serverfault.com/a/82863

Global variables that are defined outside of any method or closure can be scope restricted by using the private keyword.

import UIKit

// MARK: Local Constants

private let changeSegueId = "MasterToChange"
private let bookSegueId   = "MasterToBook"

setprecision(n) applies to the entire number, not the fractional part. You need to use the fixed-point format to make it apply to the fractional part: setiosflags(ios::fixed)

Kotlin?

  val dialogBuilder = AlertDialog.Builder(this.context)
  dialogBuilder.setTitle("Alert")
               .setMessage(message)
               .setPositiveButton("OK", null)
               .create()
               .show()

The datepicker('setDate') sets the date in the datepicket not in the input.

You should add the date and set it in the input.

var date2 = $('.pickupDate').datepicker('getDate');
var nextDayDate = new Date();
nextDayDate.setDate(date2.getDate() + 1);
$('input').val(nextDayDate);

I've created an angular directive for xCharts which is a nice js chart library http://tenxer.github.io/xcharts/. You can install it using bower, quite easy: https://github.com/radu-cigmaian/ng-xCharts

Highcharts is also a solution, but it is not free for comercial use.

Just chain them together:

.a.b {
  color: #666;
}

I decided to download the assigned port numbers from IANA, filter out the used ports, and sort each "Unassigned" range in order of most ports available, descending. This did not work, since the csv file has ranges marked as "Unassigned" that overlap other port number reservations. I manually expanded the ranges of assigned port numbers, leaving me with a list of all assigned port numbers. I then sorted that list and generated my own list of unassigned ranges.

Since this stackoverflow.com page ranked very high in my search about the topic, I figured I'd post the largest ranges here for anyone else who is interested. These are for both TCP and UDP where the number of ports in the range is at least 500.

Date is not an Integer in VB(A), it is a Double.

You can get a Date's value by passing it to CDbl().

CDbl(Now())      ' 40877.8052662037 

From the documentation:

The 1900 Date System

In the 1900 date system, the first day that is supported is January 1, 1900. When you enter a date, the date is converted into a serial number that represents the number of elapsed days starting with 1 for January 1, 1900. For example, if you enter July 5, 1998, Excel converts the date to the serial number 35981.

So in the 1900 system, 40877.805... represents 40,876 days after January 1, 1900 (29 November 2011), and ~80.5% of one day (~19:19h). There is a setting for 1904-based system in Excel, numbers will be off when this is in use (that's a per-workbook setting).

To get the integer part, use

Int(CDbl(Now())) ' 40877

which would return a LongDouble with no decimal places (i.e. what Floor() would do in other languages).

Using CLng() or Round() would result in rounding, which will return a "day in the future" when called after 12:00 noon, so don't do that.

I tried this script and got the answer

ISNUMERIC(Replace(Replace([enter_your_number],'+','A'),'-','A') + '.0e0')

for example for up question this is answer:

SELECT @MY_VAR = CAST(MY_FIELD AS INT)
FROM MY_TABLE
WHERE MY_OTHER_FIELD = 'MY_FILTER' and ISNUMERIC(Replace(Replace(MY_FIELD,'+','A'),'-','A') + '.0e0') = 1

On CentOS/RHEL:

yum install cronie

f(a, b) = s(a+b) + a, where s(n) = n*(n+1)/2

• This is a function -- it is deterministic.
• It is also injective -- f maps different values for different (a,b) pairs. You can prove this using the fact: s(a+b+1)-s(a+b) = a+b+1 < a.
• It returns quite small values -- good if your are going to use it for array indexing, as the array does not have to be big.
• It is cache-friendly -- if two (a, b) pairs are close to each other, then f maps numbers to them which are close to each other (compared to other methods).

I did not understand what You mean by:

should always yield an integer on either the positive or the negative side of integers

How can I write (greater than), (less than) characters in this forum?

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

Also have a look at:

disabling PHP-FPM fixed my issue.

jmh is a recent addition to OpenJDK and has been written by some performance engineers from Oracle. Certainly worth a look.

The jmh is a Java harness for building, running, and analysing nano/micro/macro benchmarks written in Java and other languages targetting the JVM.

Very interesting pieces of information buried in the sample tests comments.

See also:

• Avoiding Benchmarking Pitfalls on the JVM
• Discussion on the main strengths of jmh.

Set your editor to point to this program:

/Applications/TextEdit.app/Contents/MacOS/TextEdit

With SVN, you should set SVN_EDITOR environment variable to:

$ export SVN_EDITOR=/Applications/TextEdit.app/Contents/MacOS/TextEdit

And then, when you try committing something, TextEdit will launch.

It don't create normally; you need to add it by yourself.

After adding Global.asax by

• Right clicking your website -> Add New Item -> Global Application Class -> Add

You need to add a class

• Right clicking App_Code -> Add New Item -> Class -> name it Global.cs -> Add

Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.

Your Global.asax will look like this: -

<%@ Application Language="C#" Inherits="Global" %>

Your Global.cs in App_Code will look like this: -

public class Global : System.Web.HttpApplication
{
    public Global()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
    /// Many other events like begin request...e.t.c, e.t.c
}

A useful hack for me is to set the (selects) display to inline-flex. Cuts the arrow right out of my select button. Without all of the added code.

• For Fx only. -webkit appearance still needed for Chrome, etc...

File -> Export -> Web -> WAR file

OR in Kepler follow as shown below :

You can also use the special word like:

Public Sub Search()
  If "My Big String with, in the middle" Like "*,*" Then
    Debug.Print ("Found ','")
  End If
End Sub

What no-one seems to realize is that none of the System.Uri constructors correctly handles certain paths with percent signs in them.

new Uri(@"C:\%51.txt").AbsoluteUri;

This gives you "file:///C:/Q.txt" instead of "file:///C:/%2551.txt".

Neither values of the deprecated dontEscape argument makes any difference, and specifying the UriKind gives the same result too. Trying with the UriBuilder doesn't help either:

new UriBuilder() { Scheme = Uri.UriSchemeFile, Host = "", Path = @"C:\%51.txt" }.Uri.AbsoluteUri

This returns "file:///C:/Q.txt" as well.

As far as I can tell the framework is actually lacking any way of doing this correctly.

We can try to it by replacing the backslashes with forward slashes and feed the path to Uri.EscapeUriString - i.e.

new Uri(Uri.EscapeUriString(filePath.Replace(Path.DirectorySeparatorChar, '/'))).AbsoluteUri

This seems to work at first, but if you give it the path C:\a b.txt then you end up with file:///C:/a%2520b.txt instead of file:///C:/a%20b.txt - somehow it decides that some sequences should be decoded but not others. Now we could just prefix with "file:///" ourselves, however this fails to take UNC paths like \\remote\share\foo.txt into account - what seems to be generally accepted on Windows is to turn them into pseudo-urls of the form file://remote/share/foo.txt, so we should take that into account as well.

EscapeUriString also has the problem that it does not escape the '#' character. It would seem at this point that we have no other choice but making our own method from scratch. So this is what I suggest:

public static string FilePathToFileUrl(string filePath)
{
  StringBuilder uri = new StringBuilder();
  foreach (char v in filePath)
  {
    if ((v >= 'a' && v <= 'z') || (v >= 'A' && v <= 'Z') || (v >= '0' && v <= '9') ||
      v == '+' || v == '/' || v == ':' || v == '.' || v == '-' || v == '_' || v == '~' ||
      v > '\xFF')
    {
      uri.Append(v);
    }
    else if (v == Path.DirectorySeparatorChar || v == Path.AltDirectorySeparatorChar)
    {
      uri.Append('/');
    }
    else
    {
      uri.Append(String.Format("%{0:X2}", (int)v));
    }
  }
  if (uri.Length >= 2 && uri[0] == '/' && uri[1] == '/') // UNC path
    uri.Insert(0, "file:");
  else
    uri.Insert(0, "file:///");
  return uri.ToString();
}

This intentionally leaves + and : unencoded as that seems to be how it's usually done on Windows. It also only encodes latin1 as Internet Explorer can't understand unicode characters in file urls if they are encoded.

I assume the reason you don't want it to close in Debug mode, is because you want to look at the values of variables etc. So it's probably best to just insert a break-point on the closing "}" of the main function. If you don't need to debug, then Ctrl-F5 is the best option.

I figured it out! The page was rendering using IE8 mode... had

<meta http-equiv="X-UA-Compatible" content="IE=8">

in the header... changed it to

<meta http-equiv="X-UA-Compatible" content="IE=9">

9 and it worked!

If you serialize the object that you have, you can do something like this by using "System.Xml.Serialization.XmlAttributeAttribute" on every property that you want to be specified as an attribute in your model, which in my opinion is a lot easier:

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public class UserNode
{
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string userName { get; set; }

    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string passWord { get; set; }

    public int Age { get; set; }
    public string Name { get; set; }         
 }

 public class LoginNode 
 {
    public UserNode id { get; set; }
 }

Then you just serialize to XML an instance of LoginNode called "Login", and that's it!

Here you have a few examples to serialize and object to XML, but I would suggest to create an extension method in order to be reusable for other objects.

The following works for me:

composer update --no-scripts

Attach your variable to the req object, not res.

Instead of

res.somevariable = variable1;

Have:

req.somevariable = variable1;

As others have pointed out, res.locals is the recommended way of passing data through middleware.

Uncheck this in Windows Explorer.

"Hide file type extensions for known types"

Assuming they are all defined in the same assembly, you can do:

IEnumerable<AbstractDataExport> exporters = typeof(AbstractDataExport)
    .Assembly.GetTypes()
    .Where(t => t.IsSubclassOf(typeof(AbstractDataExport)) && !t.IsAbstract)
    .Select(t => (AbstractDataExport)Activator.CreateInstance(t));

In Java 6, there is a method doing exactly what you want:

private static final byte[] CDRIVES = javax.xml.bind.DatatypeConverter.parseHexBinary("e04fd020ea3a6910a2d808002b30309d")

Alternatively you could use Google Guava:

import com.google.common.io.BaseEncoding;
private static final byte[] CDRIVES = BaseEncoding.base16().lowerCase().decode("E04FD020ea3a6910a2d808002b30309d".toLowerCase());

The Guava method is overkill, when you are using small arrays. But Guava has also versions that can parse input streams. This is a nice feature when dealing with big hexadecimal inputs.

Sqlite helper class helps us to manage database creation and version management. SQLiteOpenHelper takes care of all database management activities. To use it,
1.Override onCreate(), onUpgrade() methods of SQLiteOpenHelper. Optionally override onOpen() method.
2.Use this subclass to create either a readable or writable database and use the SQLiteDatabase's four API methods insert(), execSQL(), update(), delete() to create, read, update and delete rows of your table.

Example to create a MyEmployees table and to select and insert records:

public class MyDatabaseHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "DBName";

    private static final int DATABASE_VERSION = 2;

    // Database creation sql statement
    private static final String DATABASE_CREATE = "create table MyEmployees
                                 ( _id integer primary key,name text not null);";

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Method is called during creation of the database
    @Override
    public void onCreate(SQLiteDatabase database) {
        database.execSQL(DATABASE_CREATE);
    }

    // Method is called during an upgrade of the database,
    @Override
    public void onUpgrade(SQLiteDatabase database,int oldVersion,int newVersion){
        Log.w(MyDatabaseHelper.class.getName(),
                         "Upgrading database from version " + oldVersion + " to "
                         + newVersion + ", which will destroy all old data");
        database.execSQL("DROP TABLE IF EXISTS MyEmployees");
        onCreate(database);
    }
}

Now you can use this class as below,

public class MyDB{  

    private MyDatabaseHelper dbHelper;  

    private SQLiteDatabase database;  

    public final static String EMP_TABLE="MyEmployees"; // name of table 

    public final static String EMP_ID="_id"; // id value for employee
    public final static String EMP_NAME="name";  // name of employee

    /** 
     * 
     * @param context 
     */  
    public MyDB(Context context){  
        dbHelper = new MyDatabaseHelper(context);  
        database = dbHelper.getWritableDatabase();  
    }


    public long createRecords(String id, String name){  
        ContentValues values = new ContentValues();  
        values.put(EMP_ID, id);  
        values.put(EMP_NAME, name);  
        return database.insert(EMP_TABLE, null, values);  
    }    

    public Cursor selectRecords() {
        String[] cols = new String[] {EMP_ID, EMP_NAME};  
        Cursor mCursor = database.query(true, EMP_TABLE,cols,null  
            , null, null, null, null, null);  
        if (mCursor != null) {  
            mCursor.moveToFirst();  
        }  
        return mCursor; // iterate to get each value.
    }
}

Now you can use MyDB class in you activity to have all the database operations. The create records will help you to insert the values similarly you can have your own functions for update and delete.

in my case it didn't work like following

@Query("select count(e)>0 from MyEntity e where ...")

You can return it as boolean value with following

@Query(value = "SELECT CASE  WHEN count(pl)> 0 THEN true ELSE false END FROM PostboxLabel pl ...")

For my Android projects I've used the Base64 library from here:

http://iharder.net/base64

It's a very extensive library and so far I've had no problems with it.

That's the HTML data attribute. See this for more detail: http://html5doctor.com/html5-custom-data-attributes/

Basically it's just a container of your custom data while still making the HTML valid. It's data- plus some unique identifier.

For me flex-box worked perfect to center the image.

this is my html-code:

<div class="img-wrapper">
  <img src="..." >
</div>

and this i used for css: I wanted the Image same wide as the wrapper-element, but if the height is greater than the height of the wrapper-element it should be "cropped"/not displayed.

.img-wrapper{
  width: 100%;
  height: 50%;
  overflow: hidden;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center; 
}
img {
  height: auto;
  width: 100%;
}

The installation of these tools may vary on different OS.

Under Windows, node-sass currently supports VS2015 by default, if you only have VS2013 in your box and meet any error while running the command, you can define the version of VS by adding: --msvs_version=2013. This is noted on the node-sass npm page.

So, the safe command line that works on Windows with VS2013 is: npm install --msvs_version=2013 gulp node-sass gulp-sass

You can use the flatCollect() pattern from Eclipse Collections.

MutableList<List<Object>> list = Lists.mutable.empty();
MutableList<Object> flat = list.flatCollect(each -> each);

If you can't change list from List:

List<List<Object>> list = new ArrayList<>();
List<Object> flat = ListAdapter.adapt(list).flatCollect(each -> each);

Note: I am a contributor to Eclipse Collections.

If I invoke clone() method on array of Objects of type A, how will it clone its elements?

The elements of the array will not be cloned.

Will the copy be referencing to the same objects?

Yes.

Or will it call (element of type A).clone() for each of them?

No, it will not call clone() on any of the elements.

Using jQuery UI dialog:

                            $(this).dialog("close");
                        }
                    }
                });

You can create a getter and then override that getter. It's particularly useful if the variable you are overriding is a sub-class of itself. Imagine your super class has an Object member but in your sub-class this is now more defined to be an Integer.

class Dad
{
        private static final String me = "dad";

        protected String getMe() {
            return me;
        }

        public void printMe()
        {
                System.out.println(getMe());
        }
}

class Son extends Dad
{
        private static final String me = "son";

        @Override
        protected String getMe() {
            return me;
        }
}

public void doIt()
{
        new Son().printMe(); //Prints "son"
}

__init__ is a special method in Python classes, it is the constructor method for a class. It is called whenever an object of the class is constructed or we can say it initialises a new object. Example:

    In [4]: class A:
   ...:     def __init__(self, a):
   ...:         print(a)
   ...:
   ...: a = A(10) # An argument is necessary
10

If we use A(), it will give an error TypeError: __init__() missing 1 required positional argument: 'a' as it requires 1 argument a because of __init__ .

........

__call__ when implemented in the Class helps us invoke the Class instance as a function call.

Example:

In [6]: class B:
   ...:     def __call__(self,b):
   ...:         print(b)
   ...:
   ...: b = B() # Note we didn't pass any arguments here
   ...: b(20)   # Argument passed when the object is called
   ...:
20

Here if we use B(), it runs just fine because it doesn't have an __init__ function here.

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

This might work for you:

cat <<\! >names.txt
> alison
> barb
> charlie
> david
> !
OIFS=$IFS; IFS=$'\n'; NAMES=($(<names.txt)); IFS=$OIFS
echo "${NAMES[@]}"
alison barb charlie david
echo "${NAMES[0]}"
alison
for NAME in "${NAMES[@]}";do echo $NAME;done
alison
barb
charlie
david

you can also use this to read all the lines in the file one by one then print i

#include <iostream>
#include <fstream>

using namespace std;



bool check_file_is_empty ( ifstream& file){
    return file.peek() == EOF ;
}

int main (){


    string text[256];
    int lineno ;
    ifstream file("text.txt");
    int num = 0;

    while (!check_file_is_empty(file))
    {    
        getline(file , text[num]);
        num++;
    }
    for (int i = 0; i < num ; i++)
    {
        cout << "\nthis is the text in " <<  "line " << i+1 << " :: " << text[i] << endl ;


    }
    
    system("pause");

    return 0;
}

hope this could help you :)

I got solution after working whole day on it. It is little hacky solution Added span inside td tag

Date format which Im using is dd/MM/YYYY. Tested in Datatables1.9.0

None of the suggestions worked on their own.

Here is what worked for me: chmod -R 777 $ANDROID_HOME

Then try to install it via android studio -> sdk manager. If its not there, reinstall latest version of Android studio over your current installation. HAXM will show up in SDK manager after that.

If you do not have ANDROID_HOME set, then YOU are part of the problem. The value of it can be found inside Android Studio project structure. On MAC, just type CMD ; and look at SDK Location on left.

Simply run chmod -R 775

You may also use this.Resources["mykey"]. I guess that is not much better than your own suggestion.

The following should work, but you may need to change the format:

echo date('l F jS, Y (m-d-Y)', strtotime('+3 months', strtotime($DateToAdjust)));

This is the way I would do it : saying that "list" is a <List<t>> where t is a class with a Name and a Value field; but of course you can do it with any other class type.

    list = list.Where(c=>c.Name == "height")
        .Select( new t(){Name = c.Name, Value = 30})
        .Union(list.Where(c=> c.Name != "height"))
        .ToList();

This works perfectly ! It's a simple linq expression without any loop logic. The only thing you should be aware is that the order of the lines in the result dataset will be different from the order you had in the source dataset. So if sorting is important to you, just reproduce the same order by clauses in the final linq query.

Use ChartNew.js instead of Chart.js

...

So, I have re-worked Chart.js. Most of the changes, are associated to requests in "GitHub" issues of Chart.js.

And here is a sample http://jsbin.com/lakiyu/2/edit

var newopts = {
    inGraphDataShow: true,
    inGraphDataRadiusPosition: 2,
    inGraphDataFontColor: 'white'
}
var pieData = [
    {
        value: 30,
        color: "#F38630",
    },
    {
       value: 30,
       color: "#F34353",
    },
    {
        value: 30,
        color: "#F34353",
    }
]
var pieCtx = document.getElementById('pieChart').getContext('2d');
new Chart(pieCtx).Pie(pieData, newopts);

It even provides a GUI editor http://charts.livegap.com/

So sweet.

I also found this to be useful when i wanted to place an icon with absolute positioning inside a link <a> tag.

I thought about the <img> tag first, but default styling of those tags inside links typically have border styling and/or shadow effects. Plus, it feels wrong to use an <img> tag without defining an "src" attribute whereas i'm using a background-image style sheet declaration so that the image doesn't ghost and drag.

At this point you're thinking of tags like <span> or <i> - in which case <i> makes so much sense as this type of icon.

All in all i think its benefit besides being intuitive is that it requires minimal style sheet adjustments to make this tag work as an icon.

string connectionString= ServerName + DatabaseName + SecurityType;
using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection)) {
    connection.Open();
    bulkCopy.DestinationTableName = "TableName";
    try {
        bulkCopy.WriteToServer(dataTableName);
    } catch (Exception e) {
        Console.Write(e.Message);
    }
}

Please note that the structure of the database table and the table name should be the same or it will throw an exception.

This is essentially the same thing. Use whatever you find more convenient.

Old versions of JavaScript (< ES5) require using a for..in loop:

for (var key in data) {
  if (data.hasOwnProperty(key)) {
    // do something with key
  }
}

ES5 introduces Object.keys and Array#forEach which makes this a little easier:

var data = { foo: 'bar', baz: 'quux' };

Object.keys(data); // ['foo', 'baz']
Object.keys(data).map(function(key){ return data[key] }) // ['bar', 'quux']
Object.keys(data).forEach(function (key) {
  // do something with data[key]
});

ES2017 introduces Object.values and Object.entries.

Object.values(data) // ['bar', 'quux']
Object.entries(data) // [['foo', 'bar'], ['baz', 'quux']]

You could convert your integer into a string. As the minus sign will not match the digits, you will have no negative years.

This works for me :

$scope.array1 = $scope.array1.concat(array2)

In your case it would be :

$scope.actions.data = $scope.actions.data.concat(data)

A man-in-the-middle proxy, like suggested by other answers, is a good solution if you only want to see HTTP/HTTPS traffic. Burp Suite is pretty good. It may be a pain to configure though. I'm not sure how you would convince the simulator to talk to it. You might have to set the proxy on your local Mac to your instance of a proxy server in order for it to intercept, since the simulator will make use of your local Mac's environment.

The best solution for packet sniffing (though it only works for actual iOS devices, not the simulator) I've found is to use rvictl. This blog post has a nice writeup. Basically you do:

rvictl -s <iphone-uid-from-xcode-organizer>

Then you sniff the interface it creates with with Wireshark (or your favorite tool), and when you're done shut down the interface with:

rvictl -x <iphone-uid-from-xcode-organizer>

This is nice because if you want to packet sniff the simulator, you're having to wade through traffic to your local Mac as well, but rvictl creates a virtual interface that just shows you the traffic from the iOS device you've plugged into your USB port.

Here it is:

.background {
    background:url('../img/bg/diagonalnoise.png');
    position: relative;
}

.layer {
    background-color: rgba(248, 247, 216, 0.7);
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

HTML for this:

<div class="background">
    <div class="layer">
    </div>
</div>

Of course you need to define a width and height to the .background class, if there are no other elements inside of it

I'm the author of modular-spring-contexts.

This is a small utility library to allow a more modular organization of spring contexts than is achieved by using Composing XML-based configuration metadata. modular-spring-contexts works by defining modules, which are basically stand alone application contexts and allowing modules to import beans from other modules, which are exported ín their originating module.

The key points then are

• control over dependencies between modules
• control over which beans are exported and where they are used
• reduced possibility of naming collisions of beans

A simple example would look like this:

File moduleDefinitions.xml:

<?xml version="1.0" encoding="UTF-8"?>

First, make sure you have Tkinter module installed.

sudo apt-get install python-tk

In python 2 the package name is Tkinter not tkinter.

from Tkinter import *

ref: http://www.techinfected.net/2015/09/how-to-install-and-use-tkinter-in-ubuntu-debian-linux-mint.html

For those like me who come to this page with this problem after updating Xcode but don't have an issue with the location setting, restarting my computer did the trick.

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

Why don't you just type:

seachstr

In the terminal.

The shell will say somehing like

seacrhstr: command not found 

EDIT:

Ok, I take the downvote, because the answer is stupid, I just want to know: What's wrong with this answer!!! The asker said:

and see if a command is available.

Typing the command will tell you if it is available!.

Probably he/she meant "with out executing the command" or "to include it in a script" but I cannot read his mind ( is not that I can't regularly it is just that he's wearing a mind reading deflector )

The easiest way is:

s = '"sajdkasjdsaasdasdasds"' 
import json
s = json.loads(s)

No difference here, but it matters when you have a type that has a constructor.

struct S {
    constexpr S(int);
};

const S s0(0);
constexpr S s1(1);

s0 is a constant, but it does not promise to be initialized at compile-time. s1 is marked constexpr, so it is a constant and, because S's constructor is also marked constexpr, it will be initialized at compile-time.

Mostly this matters when initialization at runtime would be time-consuming and you want to push that work off onto the compiler, where it's also time-consuming, but doesn't slow down execution time of the compiled program

You need to change Builder class to static class Builder. Then it will work fine.

I'll add this here b/c there seem to be a number of different reasons why this very frustrating error can appear. In my case, it was a question of syntax in my import statement. I had

import DataTable from '@/components/data-table/DataTable';

when I should have had

import DataTable from '@/components/data-table/';

Your project setup and configuration may vary but if you're getting this error I suggest that you check that the import syntax for your component is as expected for your project.

new String(myobj)

If you want to serialize the whole object to string, use JSON.

Oracle have announced a "statement of direction" for ODP.net and the Entity Framework:

In summary, ODP.Net beta around the end of 2010, production sometime in 2011.

The line reader.Read() is missing in your code. You should add it. It is the function which actually reads data from the database:

string conString = "Data Source=localhost;Initial Catalog=LoginScreen;Integrated Security=True";
SqlConnection con = new SqlConnection(conString);

string selectSql = "select * from Pending_Tasks";
SqlCommand com = new SqlCommand(selectSql, con);

try
{
    con.Open();

    using (SqlDataReader read = cmd.ExecuteReader())
    {
        while(reader.Read())
        {
            CustID.Text = (read["Customer_ID"].ToString());
            CustName.Text = (read["Customer_Name"].ToString());
            Add1.Text = (read["Address_1"].ToString());
            Add2.Text = (read["Address_2"].ToString());
            PostBox.Text = (read["Postcode"].ToString());
            PassBox.Text = (read["Password"].ToString());
            DatBox.Text = (read["Data_Important"].ToString());
            LanNumb.Text = (read["Landline"].ToString());
            MobNumber.Text = (read["Mobile"].ToString());
            FaultRep.Text = (read["Fault_Report"].ToString());
        }
    }
}
finally
{
    con.Close();
}

EDIT : This code works supposing you want to write the last record to your textboxes. If you want to apply a different scenario, like for example to read all the records from database and to change data in the texboxes when you click the Next button, you should create and use your own Model, or you can store data in the DataTable and refer to them later if you wish.

The accepted answer gave two locations:

here

C:\Documents and Settings\Administrator\Local Settings\Temp\VWDWebCache

and possibly here

C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\WebsiteCache

Did you try those?

Edited to add

On my Windows Vista machine, it's located in

%Temp%\VWDWebCache

and in

%LocalAppData%\Microsoft\WebsiteCache

From your additional information (regarding team edition) this comes from Clear Client TFS Cache:

Clear Client TFS Cache

Visual Studio and Team Explorer provide a caching mechanism which can get out of sync. If I have multiple instances of a single TFS which can be connected to from a single Visual Studio client, that client can become confused.

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

Many good answers here already, although you also need to keep in mind that if you are doing long-running processing on the UI thread (generally a bad idea), then you won't see the marquee moving either.

Use the below:

var regEx = new RegExp(pattern1+'|'+pattern2, 'gi');

str.match(regEx);

Use a Queue

Queue<String> qe=new LinkedList<String>();

qe.add("a");
qe.add("b");
qe.add("c");
qe.add("d");

System.out.println(qe.poll()); //returns a
System.out.println(qe.poll()); //returns b
System.out.println(qe.poll()); //returns c
System.out.println(qe.poll()); //returns d

There's five simple methods of a Queue

• element() -- Retrieves, but does not remove, the head of this queue.

• offer(E o) -- Inserts the specified element into this queue, if
  possible.

• peek() -- Retrieves, but does not remove, the head of this queue, returning null if this queue is empty.

• poll() -- Retrieves and removes the head of this queue, or null if this queue is empty.

• remove() -- Retrieves and removes the head of this queue.

If you are looking for single characters, you can use String.IndexOfAny().

If you want arbitrary strings, then I'm not aware of a .NET method to achieve that "directly", although a regular expression would work.

It's working better. Try it.

let value = $("select#yourId option").filter(":selected").val();

Mr @Scott Stanchfield wrote an excellent answer. Here is the class that would you to verify exactly what he meant:

public class Dog {

    String dog ;
    static int x_static;
    int y_not_static;

    public String getName()
    {
        return this.dog;
    }

    public Dog(String dog)
    {
        this.dog = dog;
    }

    public void setName(String name)
    {
        this.dog = name;
    }

    public static void foo(Dog someDog)
    {
        x_static = 1;
        // y_not_static = 2;  // not possible !!
        someDog.setName("Max");     // AAA
        someDog = new Dog("Fifi");  // BBB
        someDog.setName("Rowlf");   // CCC
    }

    public static void main(String args[])
    {
        Dog myDog = new Dog("Rover");
        foo(myDog);
        System.out.println(myDog.getName());
    }
}

So, we pass from main() a dog called Rover, then we assign a new address to the pointer that we passed, but at the end, the name of the dog is not Rover, and not Fifi, and certainly not Rowlf, but Max.

You shouldn't have to worry about the stack leaking memory (it is highly uncommon). The only time you can have the stack get out of control is with infinite (or really deep) recursion.

This is just the heap. Sorry, didn't read your question fully at first.

You need to run the JVM with the following command line argument.

-Xmx<ammount of memory>

Example:

-Xmx1024m

That will allow a max of 1GB of memory for the JVM.

PHP 8 update

PHP 8 includes new str_starts_with and str_ends_with functions that finally provide a performant and convenient solution to this problem:

$str = "beginningMiddleEnd";
if (str_starts_with($str, "beg")) echo "printed\n";
if (str_starts_with($str, "Beg")) echo "not printed\n";
if (str_ends_with($str, "End")) echo "printed\n";
if (str_ends_with($str, "end")) echo "not printed\n";

The RFC for this feature provides more information, and also a discussion of the merits and problems of obvious (and not-so-obvious) userland implementations.

For...in loop

The for...in loop improves upon the weaknesses of the for loop by eliminating the counting logic and exit condition.

Example:

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const index in digits) {
  console.log(digits[index]);
}

But, you still have to deal with the issue of using an index to access the values of the array, and that stinks; it almost makes it more confusing than before.

Also, the for...in loop can get you into big trouble when you need to add an extra method to an array (or another object). Because for...in loops loop over all enumerable properties, this means if you add any additional properties to the array's prototype, then those properties will also appear in the loop.

Array.prototype.decimalfy = function() {
  for (let i = 0; i < this.length; i++) {
    this[i] = this[i].toFixed(2);
  }
};

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const index in digits) {
  console.log(digits[index]);
}

Prints:

0

1

2

3

4

5

6

7

8

9

function() { for (let i = 0; i < this.length; i++) { this[i] = this[i].toFixed(2); } }

This is why for...in loops are discouraged when looping over arrays.

NOTE: The forEach loop is another type of for loop in JavaScript. However, forEach() is actually an array method, so it can only be used exclusively with arrays. There is also no way to stop or break a forEach loop. If you need that type of behavior in your loop, you’ll have to use a basic for loop.

For...of loop

The for...of loop is used to loop over any type of data that is iterable.

Example:

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const digit of digits) {
  console.log(digit);
}

Prints:

0

1

2

3

4

5

6

7

8

9

This makes the for...of loop the most concise version of all the for loops.

But wait, there’s more! The for...of loop also has some additional benefits that fix the weaknesses of the for and for...in loops.

You can stop or break a for...of loop at anytime.

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const digit of digits) {
  if (digit % 2 === 0) {
    continue;
  }
  console.log(digit);
}

Prints:

1

3

5

7

9

And you don’t have to worry about adding new properties to objects. The for...of loop will only loop over the values in the object.

Just put this line at the bottom of your app-module's (not project root's) gradle file.

apply plugin: 'com.google.gms.google-services'

Then rebuild your project.

I used the code below and it worked for me.

String email="";
    SqlDataReader reader=cmd.ExecuteReader();
    if(reader.Read()){
        email=reader["Email"].ToString();
    }

String To=email;

For Python 3.x

import urllib.request
from urllib.error import HTTPError
try:
    urllib.request.urlretrieve(url, fullpath)
except urllib.error.HTTPError as err:
    print(err.code)

Here try this it works 100%

    }  
}

To collect in a mutable list:

targetList = sourceList.stream()
                       .filter(i -> i > 100) //apply filter
                       .collect(Collectors.toList());

To collect in a immutable list:

targetList = sourceList.stream()
                       .filter(i -> i > 100) //apply filter
                       .collect(Collectors.toUnmodifiableList());

Explanation of collect from the JavaDoc:

Performs a mutable reduction operation on the elements of this stream using a Collector. A Collector encapsulates the functions used as arguments to collect(Supplier, BiConsumer, BiConsumer), allowing for reuse of collection strategies and composition of collect operations such as multiple-level grouping or partitioning. If the stream is parallel, and the Collector is concurrent, and either the stream is unordered or the collector is unordered, then a concurrent reduction will be performed (see Collector for details on concurrent reduction.)

This is a terminal operation.

When executed in parallel, multiple intermediate results may be instantiated, populated, and merged so as to maintain isolation of mutable data structures. Therefore, even when executed in parallel with non-thread-safe data structures (such as ArrayList), no additional synchronization is needed for a parallel reduction.

I had this same problem. For me, the reason turned out to be that I had a mismatch in the name of the class and the name of the file. I declared class "GenSig" in a file called "SignatureTester.java".

I changed the name of the class to "SignatureTester", and the "Run as Java Application" option showed up immediately.

Simple tree command will do the job. For example: tree -o readme.md will print the tree structure of your current working directory and write it to readme.md. Then open readme.md file in one of text editor like Sublime and wrap its content within a pair of triple backticks (```).

FYI: you might have to brew install tree in OSX if it's not already installed. In Linux and Windows it should just work fine. Also in windows you might have to replace hyphen with forward slash.

I hope this helps.

I assume the C string is in a fixed memory, so if you replace spaces you have to shift all characters.

The easiest seems to be to create new string and iterate over the original one and copy only non space characters.

Combine Mixin with Extend

I just stumbled upon a combination of Mixin and Extend:

reused blocks:

.block1 { box-shadow: 0 5px 10px #000; }

.block2 { box-shadow: 5px 0 10px #000; }

.block3 { box-shadow: 0 0 1px #000; }

dynamic mixin:

@mixin customExtend($class){ @extend .#{$class}; }

use mixin:

like: @include customExtend(block1);

h1 {color: fff; @include customExtend(block2);}

Sass will compile only the mixins content to the extended blocks, which makes it able to combine blocks without generating duplicate code. The Extend logic only puts the classname of the Mixin import location in the block1, ..., ... {box-shadow: 0 5px 10px #000;}

That error means that a function call is only matched by an existing function if all its arguments are of the same type and passed in same order. So if the next f() function

create function f() returns integer as $$ 
    select 1;
$$ language sql;

is called as

select f(1);

It will error out with

ERROR:  function f(integer) does not exist
LINE 1: select f(1);
               ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

because there is no f() function that takes an integer as argument.

So you need to carefully compare what you are passing to the function to what it is expecting. That long list of table columns looks like bad design.

I needed to do a little bit of testing myself of a button component. These tests work for me ;-)

import { shallow } from "enzyme";
import * as React from "react";
import Button from "../button.component";

describe("Button Component Tests", () => {
    it("Renders correctly in DOM", () => {
        shallow(
            <Button text="Test" />
        );
    });
    it("Expects to find button HTML element in the DOM", () => {
        const wrapper = shallow(<Button text="test"/>)
        expect(wrapper.find('button')).toHaveLength(1);
    });

    it("Expects to find button HTML element with className test in the DOM", () => {
        const wrapper = shallow(<Button className="test" text="test"/>)
        expect(wrapper.find('button.test')).toHaveLength(1);
    });

    it("Expects to run onClick function when button is pressed in the DOM", () => {
        const mockCallBackClick = jest.fn();
        const wrapper = shallow(<Button onClick={mockCallBackClick} className="test" text="test"/>);
        wrapper.find('button').simulate('click');
        expect(mockCallBackClick.mock.calls.length).toEqual(1);
    });
});

In Font Awesome 5, you can create custom icons with your own SVG data. Here's a demo GitHub repo that you can play with. And here's a CodePen that shows how something similar might be done in <script> blocks.

In either case, it simply involves using library.add() to add an object like this:

export const faSomeObjectName = {
  // Use a prefix like 'fac' that doesn't conflict with a prefix in the standard Font Awesome styles
  // (So avoid fab, fal, fas, far, fa)
  prefix: string,
  iconName: string, // Any name you like
  icon: [
    number, // width
    number, // height
    string[], // ligatures
    string, // unicode (if relevant)
    string // svg path data
  ]
}

Note that the element labelled by the comment "svg path data" in the code sample is what will be assigned as the value of the d attribute on a <path> element that is a child of the <svg>. Like this (leaving out some details for clarity):

<svg>
  <path d=SVG_PATH_DATA></path>
</svg>

(Adapted from my similar answer here: https://stackoverflow.com/a/50338775/4642871)

It sounds like you're confused between pointers and arrays. Pointers and arrays (in this case char * and char []) are not the same thing.

• An array char a[SIZE] says that the value at the location of a is an array of length SIZE
• A pointer char *a; says that the value at the location of a is a pointer to a char. This can be combined with pointer arithmetic to behave like an array (eg, a[10] is 10 entries past wherever a points)

In memory, it looks like this (example taken from the FAQ):

 char a[] = "hello";  // array

   +---+---+---+---+---+---+
a: | h | e | l | l | o |\0 |
   +---+---+---+---+---+---+

 char *p = "world"; // pointer

   +-----+     +---+---+---+---+---+---+
p: |  *======> | w | o | r | l | d |\0 |
   +-----+     +---+---+---+---+---+---+

It's easy to be confused about the difference between pointers and arrays, because in many cases, an array reference "decays" to a pointer to it's first element. This means that in many cases (such as when passed to a function call) arrays become pointers. If you'd like to know more, this section of the C FAQ describes the differences in detail.

One major practical difference is that the compiler knows how long an array is. Using the examples above:

char a[] = "hello";  
char *p =  "world";  

sizeof(a); // 6 - one byte for each character in the string,
           // one for the '\0' terminator
sizeof(p); // whatever the size of the pointer is
           // probably 4 or 8 on most machines (depending on whether it's a 
           // 32 or 64 bit machine)

Without seeing your code, it's hard to recommend the best course of action, but I suspect changing to use pointers everywhere will solve the problems you're currently having. Take note that now:

• You will need to initialise memory wherever the arrays used to be. Eg, char a[10]; will become char *a = malloc(10 * sizeof(char));, followed by a check that a != NULL. Note that you don't actually need to say sizeof(char) in this case, because sizeof(char) is defined to be 1. I left it in for completeness.

• Anywhere you previously had sizeof(a) for array length will need to be replaced by the length of the memory you allocated (if you're using strings, you could use strlen(), which counts up to the '\0').

• You will need a make a corresponding call to free() for each call to malloc(). This tells the computer you are done using the memory you asked for with malloc(). If your pointer is a, just write free(a); at a point in the code where you know you no longer need whatever a points to.

As another answer pointed out, if you want to get the address of the start of an array, you can use:

char* p = &a[0] 

You can read this as "char pointer p becomes the address of element [0] of a".

I just learned the comm command from this thread, but wanted to add something extra: if the files are not sorted, and you don't want to touch the original files, you can pipe the outptut of the sort command. This leaves the original files intact. Works in bash, I can't say about other shells.

comm -1 -2 <(sort file1) <(sort file2)

This can be extended to compare command output, instead of files:

comm -1 -2 <(ls /dir1 | sort) <(ls /dir2 | sort)

Use a Flexbox, and put the border on the form.

The best way to do this now (2019) is with a flexbox.

• Put the border on the containing element (in this case I've used the form, but you could use a div).
• Use a flexbox layout to arrange the input and the button side by side. Allow the input to stretch to take up all available space.
• Now hide the input by removing its border.

Run the snippet below to see what you get.

form {_x000D_
  /* This bit sets up the horizontal layout */_x000D_
  display:flex;_x000D_
  flex-direction:row;_x000D_
  _x000D_
  /* This bit draws the box around it */_x000D_
  border:1px solid grey;_x000D_
_x000D_
  /* I've used padding so you can see the edges of the elements. */_x000D_
  padding:2px;_x000D_
}_x000D_
_x000D_
input {_x000D_
  /* Tell the input to use all the available space */_x000D_
  flex-grow:2;_x000D_
  /* And hide the input's outline, so the form looks like the outline */_x000D_
  border:none;_x000D_
}_x000D_
_x000D_
input:focus {_x000D_
  /* removing the input focus blue box. Put this on the form if you like. */_x000D_
  outline: none;_x000D_
}_x000D_
_x000D_
button {_x000D_
  /* Just a little styling to make it pretty */_x000D_
  border:1px solid blue;_x000D_
  background:blue;_x000D_
  color:white;_x000D_
}

<form>_x000D_
  <input />_x000D_
  <button>Go</button>_x000D_
</form>

Why this is good

• It will stretch to any width.
• The button will always be just as big as it needs to be. It won't stretch if the screen is wide, or shrink if the screen is narrow.
• The input text will not go behind the button.

Caveats and Browser Support

There's limited Flexbox support in IE9, so the button will not be on the right of the form. IE9 has not been supported by Microsoft for some years now, so I'm personally quite comfortable with this.

I've used minimal styling here. I've left in the padding to show the edges of things. You can obviously make this look however you want it to look with rounded corners, drop shadows, etc..

I ran into this problem on NetBeans when working with a ready-made project from this Murach JSP book. The problem was caused by using the 5.1.23 Connector J with a MySQL 8.0.13 Database. I needed to replace the old driver with a new one. After downloading the Connector J, this took three steps.

How to replace NetBeans project Connector J:

1. Download the current Connector J from here. Then copy it in your OS.

2. In NetBeans, click on the Files tab which is next to the Projects tab. Find the mysql-connector-java-5.1.23.jar or whatever old connector you have. Delete this old connector. Paste in the new Connector.

3. Click on the Projects tab. Navigate to the Libraries folder. Delete the old mysql connector. Right click on the Libraries folder. Select Add Jar / Folder. Navigate to the location where you put the new connector, and select open.

4. In the Project tab, right click on the project. Select Resolve Data Sources on the bottom of the popup menu. Click on Add Connection. At this point NetBeans skips forward and assumes you want to use the old connector. Click the Back button to get back to the skipped window. Remove the old connector, and add the new connector. Click Next and Test Connection to make sure it works.

For video reference, I found this to be useful. For IntelliJ IDEA, I found this to be useful.

I had the same error and could not figure it out with the other answers. I found that we can "Consolidate" NuGet packages.

1. Right click on the solution
2. Click Manage Nuget Packages
3. Consolidate tab and update to the same version.

It works like this:

h4 {
    display:inline;
}
h4:after {
    content:"\a";
    white-space: pre;
}

Example: http://jsfiddle.net/Bb2d7/

The trick comes from here: https://stackoverflow.com/a/66000/509752 (to have more explanation)

I think it makes clear with the namespace, as we can create our own attributes and if the user specified attribute is the same as the Android one it avoid the conflict of the namespace.

simply change <div> to <tbody>

<table id="authenticationSetting" style="display: none">
  <tbody id="authenticationOuterIdentityBlock" style="display: none;">
    <tr>
      <td class="orionSummaryHeader">
        <orion:message key="policy.wifi.enterprise.authentication.outeridentitity" />:</td>
      <td class="orionSummaryColumn">
        <orion:textbox id="authenticationOuterIdentity" size="30" />
      </td>
    </tr>
  </tbody>
</table>

try

amtf =  amtf.Insert(amtf.Length - 2, ".");

If you start Notepad and then File -> Save As -> Write .htaccess and choose "All Files" as the type - then it will create the .htaccess file for you.

Where I work we have been using this method on all of our repositories for a few years without any problems (except when we create a new repository and forget to set it up this way):

1. Set 'sharedRepository = true' in the config file's '[core]' section.

2. Change the group id of the repository to a group shared by all users who are allowed to push to it:

   chgrp -R shared_group /git/our_repos
   chmod -R g+w /git/our_repos
   

3. Set the setgid bit on all directories in the repository so that new files/directories keep the same group:

   find /git/our_repos -type d -exec chmod g+s {} +
   

4. Add this line to the pre-receive hook in the repository to ensure new file permissions allow group read/write:

   umask 007
   

You are correct in that glibc uses symbol versioning. If you are curious, the symbol versioning implementation introduced in glibc 2.1 is described here and is an extension of Sun's symbol versioning scheme described here.

One option is to statically link your binary. This is probably the easiest option.

You could also build your binary in a chroot build environment, or using a glibc-new => glibc-old cross-compiler.

According to the http://www.trevorpounds.com blog post Linking to Older Versioned Symbols (glibc), it is possible to to force any symbol to be linked against an older one so long as it is valid by using the same .symver pseudo-op that is used for defining versioned symbols in the first place. The following example is excerpted from the blog post.

The following example makes use of glibc’s realpath, but makes sure it is linked against an older 2.2.5 version.

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

__asm__(".symver realpath,realpath@GLIBC_2.2.5");
int main()
{
    const char* unresolved = "/lib64";
    char resolved[PATH_MAX+1];

    if(!realpath(unresolved, resolved))
        { return 1; }

    printf("%s\n", resolved);

    return 0;
}

Maybe someone else can explain the reasons behind your problem but you can solve it by specifying the height of the container and then setting the height of the image to be 100%. It is important that the width of the image appears before the height.

<html>
    <head>
        <style>
            .container {  
                background: blue; 
                padding: 10px;
                height: 100%;
                max-height: 200px; 
                max-width: 300px; 
            }

            .container img {
                width: 100%;
                height: 100%
            }
        </style>
    </head>
    <body>
        <div class="container">
            <img src="http://placekitten.com/400/500" />
        </div>
    </body>
</html>

DEADLOCK Deadlock is a condition in which a task waits indefinitely for conditions that can never be satisfied - task claims exclusive control over shared resources - task holds resources while waiting for other resources to be released - tasks cannot be forced to relinguish resources - a circular waiting condition exists

LIVELOCK Livelock conditions can arise when two or more tasks depend on and use the some resource causing a circular dependency condition where those tasks continue running forever, thus blocking all lower priority level tasks from running (these lower priority tasks experience a condition called starvation)

In case you are using zsh you can use for example the -E or -i switch:

history -E

If you do a man zshoptions or man zshbuiltins you can find out more information about these switches as well as other info related to history:

Also when listing,
 -d     prints timestamps for each event
 -f     prints full time-date stamps in the US `MM/DD/YY hh:mm' format
 -E     prints full time-date stamps in the European `dd.mm.yyyy hh:mm' format
 -i     prints full time-date stamps in ISO8601 `yyyy-mm-dd hh:mm' format
 -t fmt prints time and date stamps in the given format; fmt is formatted with the strftime function with the zsh extensions  described  for  the  %D{string} prompt format in the section EXPANSION OF PROMPT SEQUENCES in zshmisc(1).  The resulting formatted string must be no more than 256 characters or will not be printed
 -D     prints elapsed times; may be combined with one of the options above

The accepted answer works for columns that are of datatype string. For completeness: I come across this question when searching how to do this when the columns are of datatypes: date and time.

df.apply(lambda r : pd.datetime.combine(r['date_column_name'],r['time_column_name']),1)

If d = date(2011, 1, 1) is in UTC:

>>> from datetime import datetime, date
>>> import calendar
>>> timestamp1 = calendar.timegm(d.timetuple())
>>> datetime.utcfromtimestamp(timestamp1)
datetime.datetime(2011, 1, 1, 0, 0)

If d is in local timezone:

>>> import time
>>> timestamp2 = time.mktime(d.timetuple()) # DO NOT USE IT WITH UTC DATE
>>> datetime.fromtimestamp(timestamp2)
datetime.datetime(2011, 1, 1, 0, 0)

timestamp1 and timestamp2 may differ if midnight in the local timezone is not the same time instance as midnight in UTC.

mktime() may return a wrong result if d corresponds to an ambiguous local time (e.g., during DST transition) or if d is a past(future) date when the utc offset might have been different and the C mktime() has no access to the tz database on the given platform. You could use pytz module (e.g., via tzlocal.get_localzone()) to get access to the tz database on all platforms. Also, utcfromtimestamp() may fail and mktime() may return non-POSIX timestamp if "right" timezone is used.

To convert datetime.date object that represents date in UTC without calendar.timegm():

DAY = 24*60*60 # POSIX day in seconds (exact value)
timestamp = (utc_date.toordinal() - date(1970, 1, 1).toordinal()) * DAY
timestamp = (utc_date - date(1970, 1, 1)).days * DAY

How can I get a date converted to seconds since epoch according to UTC?

To convert datetime.datetime (not datetime.date) object that already represents time in UTC to the corresponding POSIX timestamp (a float).

Python 3.3+

datetime.timestamp():

from datetime import timezone

timestamp = dt.replace(tzinfo=timezone.utc).timestamp()

Note: It is necessary to supply timezone.utc explicitly otherwise .timestamp() assume that your naive datetime object is in local timezone.

Python 3 (< 3.3)

From the docs for datetime.utcfromtimestamp():

There is no method to obtain the timestamp from a datetime instance, but POSIX timestamp corresponding to a datetime instance dt can be easily calculated as follows. For a naive dt:

timestamp = (dt - datetime(1970, 1, 1)) / timedelta(seconds=1)

And for an aware dt:

timestamp = (dt - datetime(1970,1,1, tzinfo=timezone.utc)) / timedelta(seconds=1)

Interesting read: Epoch time vs. time of day on the difference between What time is it? and How many seconds have elapsed?

See also: datetime needs an "epoch" method

Python 2

To adapt the above code for Python 2:

timestamp = (dt - datetime(1970, 1, 1)).total_seconds()

where timedelta.total_seconds() is equivalent to (td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 10**6 computed with true division enabled.

Example

from __future__ import division
from datetime import datetime, timedelta

def totimestamp(dt, epoch=datetime(1970,1,1)):
    td = dt - epoch
    # return td.total_seconds()
    return (td.microseconds + (td.seconds + td.days * 86400) * 10**6) / 10**6 

now = datetime.utcnow()
print now
print totimestamp(now)

Beware of floating-point issues.

Output

How to convert an aware datetime object to POSIX timestamp

assert dt.tzinfo is not None and dt.utcoffset() is not None
timestamp = dt.timestamp() # Python 3.3+

On Python 3:

from datetime import datetime, timedelta, timezone

epoch = datetime(1970, 1, 1, tzinfo=timezone.utc)
timestamp = (dt - epoch) / timedelta(seconds=1)
integer_timestamp = (dt - epoch) // timedelta(seconds=1)

On Python 2:

# utc time = local time              - utc offset
utc_naive  = dt.replace(tzinfo=None) - dt.utcoffset()
timestamp = (utc_naive - datetime(1970, 1, 1)).total_seconds()

Assertions don't survive reality

Usually assertions don't survive the contact with real world data. It's a part of the process of software engineering to decide, with which data you want to deal and which are out of scope.

Cyclic family graphs

Regarding family "trees" (in fact it are full blown graphs, including cycles), there is a nice anecdote:

I married a widow who had a grown daughter. My father, who often visited us, fell in love with my step-daughter and married her. As a result, my father became my son, and my daughter became my mother. Some time later, I gave my wife a son, who was the brother of my father, and my uncle. My father's wife (who is also my daughter and my mother) got a son. As a result, I got a brother and a grandson in the same person. My wife is now my grandmother, because she is my mother's mother. So I am the husband of my wife, and at the same time the step-grandson of my wife. In other words, I'm my own grandpa.

Things get even more strange, when you take surrogates or "fuzzy fatherhood" into account.

How to deal with that

Define cycles as out-of-scope

You could decide that your software should not deal with such rare cases. If such a case occurs, the user should use a different product. This makes dealing with the more common cases much more robust, because you can keep more assertions and a simpler data model.

In this case, add some good import and export features to your software, so the user can easily migrate to a different product when necessary.

Allow manual relations

You could allow the user to add manual relations. These relations are not "first-class citizens", i.e. the software takes them as-is, doesn't check them and doesn't handle them in the main data model.

The user can then handle rare cases by hand. Your data model will still stay quite simple and your assertions will survive.

Be careful with manual relations. There is a temptation to make them completely configurable and hence create a fully configurable data model. This will not work: Your software will not scale, you will get strange bugs and finally the user interface will become unusable. This anti-pattern is called "soft coding", and "The daily WTF" is full of examples for that.

Make your data model more flexible, skip assertions, test invariants

The last resort would be making your data model more flexible. You would have to skip nearly all assertions and base your data model on a full blown graph. As the above example shows, it is easily possible to be your own grandfather, so you can even have cycles.

In this case, you should extensively test your software. You had to skip nearly all assertions, so there is a good chance for additional bugs.

Use a test data generator to check unusual test cases. There are quick check libraries for Haskell, Erlang or C. For Java / Scala there are ScalaCheck and Nyaya. One test idea would be to simulate a random population, let it interbreed at random, then let your software first import and then export the result. The expectation would be, that all connections in the output are also in the input and vice verse.

A case, where a property stays the same is called an invariant. In this case, the invariant is the set of "romantic relations" between the individuals in the simulated population. Try to find as much invariants as possible and test them with randomly generated data. Invariants can be functional, e.g.:

• an uncle stays an uncle, even when you add more "romantic relations"
• every child has a parent
• a population with two generations has at least one grand-parent

Or they can be technical:

• Your software will not crash on a graph up to 10 billion members (no matter how many interconnections)
• Your software scales with O(number-of-nodes) and O(number-of-edges^2)
• Your software can save and re-load every family graph up to 10 billion members

By running the simulated tests, you will find lots of strange corner cases. Fixing them will take a lot of time. Also you will lose a lot of optimizations, your software will run much slower. You have to decide, if it is worth it and if this is in the scope of your software.

#ifndef MY_HEADER_H
# define MY_HEADER_H

//put your function headers here

#endif

MY_HEADER_H serves as a double-inclusion guard.

For the function declaration, you only need to define the signature, that is, without parameter names, like this:

int foo(char*);

If you really want to, you can also include the parameter's identifier, but it's not necessary because the identifier would only be used in a function's body (implementation), which in case of a header (parameter signature), it's missing.

This declares the function foo which accepts a char* and returns an int.

In your source file, you would have:

#include "my_header.h"

int foo(char* name) {
   //do stuff
   return 0;
}

A key is just a normal index. A way over simplification is to think of it like a card catalog at a library. It points MySQL in the right direction.

A unique key is also used for improved searching speed, but it has the constraint that there can be no duplicated items (there are no two x and y where x is not y and x == y).

The manual explains it as follows:

A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. This constraint does not apply to NULL values except for the BDB storage engine. For other engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL. If you specify a prefix value for a column in a UNIQUE index, the column values must be unique within the prefix.

A primary key is a 'special' unique key. It basically is a unique key, except that it's used to identify something.

The manual explains how indexes are used in general: here.

In MSSQL, the concepts are similar. There are indexes, unique constraints and primary keys.

Untested, but I believe the MSSQL equivalent is:

CREATE TABLE tmp (
  id int NOT NULL PRIMARY KEY IDENTITY,
  uid varchar(255) NOT NULL CONSTRAINT uid_unique UNIQUE,
  name varchar(255) NOT NULL,
  tag int NOT NULL DEFAULT 0,
  description varchar(255),
);

CREATE INDEX idx_name ON tmp (name);
CREATE INDEX idx_tag ON tmp (tag);

Edit: the code above is tested to be correct; however, I suspect that there's a much better syntax for doing it. Been a while since I've used SQL server, and apparently I've forgotten quite a bit :).

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

It should help you.

This will return all URLs with page name. (e.g.: index.php?id=1&name=rr&class=10).

more generally, this could also look like this:

        p = multiprocessing.Process(target=f, args=(i,param))
        jobs.append(p)
    for i in chunks(jobs,numberOfThreads):
        for j in i:
            j.start()
        for j in i:
            j.join()

Of course, that way is quite cruel (since it waits for every process in a junk until it continues with the next chunk). Still it works well for approx equal run times of the function calls.

If you are too lazy like me: conda install -c conda-forge boost

I had some struggle to access the previous url inside a guard.
Without implementing a custom solution, this one is working for me.

public constructor(private readonly router: Router) {
};

public ngOnInit() {
   this.router.getCurrentNavigation().previousNavigation.initialUrl.toString();
}

The initial url will be the previous url page.

You can use AJAX for that. Whenever you scan a barcode, your scanner will act as if it is a keyboard typing into your input type="text" components. With JavaScript, capture the corresponding event, and send HTTP REQUEST and process responses accordingly.

I actually found a better way using the jQuery approach

var box = {

config:{
 color: 'red'
},

init:function(config){
 $.extend(this.config,config);
}

};

var myBox = box.init({
 color: blue
});

I think that it's not supported. If you have a look at this DefaultValueAccessor directive (see https://github.com/angular/angular/blob/master/modules/angular2/src/common/forms/directives/default_value_accessor.ts#L23). You will see that the value used to update the bound element is $event.target.value.

This doesn't apply in the case of inputs with type file since the file object can be reached $event.srcElement.files instead.

For more details, you can have a look at this plunkr: https://plnkr.co/edit/ozZqbxIorjQW15BrDFrg?p=info:

@Component({
  selector: 'my-app',
  template: `
    <div>
      <input type="file" (change)="onChange($event)"/>
    </div>
  `,
  providers: [ UploadService ]
})
export class AppComponent {
  onChange(event) {
    var files = event.srcElement.files;
    console.log(files);
  }
}

Supposing you use sql server:

WHERE StartTime BETWEEN DATEADD(HOUR, -1, GetDate())
                    AND DATEADD(HOUR, 1, GetDate())

This was for my own project and I'm sharing it here too.

There are a number of "is methods" on strings. islower() and isupper() should meet your needs:

>>> 'hello'.islower()
True

>>> [m for m in dir(str) if m.startswith('is')]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

Here's an example of how to use those methods to classify a list of strings:

>>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG']
>>> [word for word in words if word.islower()]
['quick', 'jumped', 'the']
>>> [word for word in words if word.isupper()]
['BROWN', 'OVER', 'DOG']
>>> [word for word in words if not word.islower() and not word.isupper()]
['The', 'Fox', 'Lazy']

You can try: ng serve --configuration=dev/prod

To build use: ng build --prod --configuration=dev

1. As mentioned by @Justin Breitfeller, @Vidar Wahlberg solution is a hack which might not work in future version of Android.
2. @Vidar Wahlberg perfer a hack because other solution might "cause the map to be recreated and redrawn, which isn't always desirable". Map redraw could be prevented by maintaining the old map fragment, rather than creating a new instance every time.
3. @Matt solution doesn't work for me (IllegalStateException)
4. As quoted by @Justin Breitfeller, "You cannot inflate a layout into a fragment when that layout includes a . Nested fragments are only supported when added to a fragment dynamically."

My solution:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,                              Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_map_list, container, false);

    // init
    //mapFragment = (SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map);
    // don't recreate fragment everytime ensure last map location/state are maintain
    if (mapFragment == null) {
        mapFragment = SupportMapFragment.newInstance();
        mapFragment.getMapAsync(this);
    }
    FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
    // R.id.map is a layout
    transaction.replace(R.id.map, mapFragment).commit();

    return view;
}

firstly you have to change the drive, which is allocated to your usb.

follow these step to access your pendrive using CMD. 1- type drivename follow by the colon just like k: 2- type dir it will show all the files and directory in your usb 3- now you can access any file or directory of your usb.

It's true that true and false don't represent any numerical values in Javascript.

In some languages (e.g. C, VB), the boolean values are defined as actual numerical values, so they are just different names for 1 and 0 (or -1 and 0).

In some other languages (e.g. Pascal, C#), there is a distinct boolean type that is not numerical. It's possible to convert between boolean values and numerical values, but it doesn't happen automatically.

Javascript falls in the category that has a distinct boolean type, but on the other hand Javascript is quite keen to convert values between different data types.

For example, eventhough a number is not a boolean, you can use a numeric value where a boolean value is expected. Using if (1) {...} works just as well as if (true) {...}.

When comparing values, like in your example, there is a difference between the == operator and the === operator. The == equality operator happily converts between types to find a match, so 1 == true evaluates to true because true is converted to 1. The === type equality operator doesn't do type conversions, so 1 === true evaluates to false because the values are of different types.

Using python and telethon it's very easy to get chat id. This solution is best for those who work with telegram API.

If you don't have telethon, run this:

pip install telethon

If you don't have a registered app with telegram, register one: The link is this: https://my.telegram.org/

Then run the following code:

from telethon import InteractiveTelegramClient
from telethon.utils.tl_utils import get_display_name

client = InteractiveTelegramClient('session_id', 'YOUR_PHONE_NUMBER', api_id=1234YOURAPI_ID, api_hash='YOUR_API_HASH')

dialog_count = 10
dialogs, entities = client.get_dialogs(dialog_count)
for i, entity in enumerate(entities):
                    i += 1  # 1-based index
                    print('{}. {}. id: {}'.format(i, get_display_name(entity), entity.id))

I'd iterate through the options, comparing the text to what I want to be selected, then set the selected attribute on that option. Once you find the correct one, terminate the iteration (unless you have a multiselect).

 $('#dropdown').find('option').each( function() {
      var $this = $(this);
      if ($this.text() == 'B') {
         $this.attr('selected','selected');
         return false;
      }
 });

I experienced the same issue on a Drupal site. After enabling the Geocoding API on the Google Cloud Platform, works for me. On my setup I require two APIs, Geocoding and Maps Javascript APIs.

Its only possible to get the WSDL if the webservice is configured to deliver it. Therefor you have to specify a serviceBehavior and enable httpGetEnabled:

<serviceBehaviors>
    <behavior name="BindingBehavior">
        <serviceMetadata httpGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
</serviceBehaviors>

In case the webservice is only accessible via https you have to enable httpsGetEnabled instead of httpGetEnabled.

by using property css:

background-size: cover;

Just use TOP 100 Percent in the Select:

     CREATE VIEW [schema].[VIEWNAME] (
         [COLUMN1],
         [COLUMN2],
         [COLUMN3],
         [COLUMN4])
     AS 
        SELECT TOP 100 PERCENT 
         alias.[COLUMN1],
         alias.[COLUMN2],
         alias.[COLUMN3],
         alias.[COLUMN4]
        FROM 
           [schema].[TABLENAME] AS alias
          ORDER BY alias.COLUMN1
     GO

Your problem is that the indices returned by match.start() correspond to the position of the character as it appeared in the original string when you matched it; however, as you rewrite the string c every time, these indices become incorrect.

The best approach to solve this is to use replaceAll, for example:

        System.out.println(c.replaceAll("[^a-zA-Z0-9]", ""));

In native LINQ you may use combination of Contains/StartsWith/EndsWith or RegExp.

In LINQ2SQL use method SqlMethods.Like()

    from i in db.myTable
    where SqlMethods.Like(i.field, "tra%ata")
    select i

add Assembly: System.Data.Linq (in System.Data.Linq.dll) to use this feature.

Make sure that your certificate is connected with your private key:

Open Keychain access, login, Certificates. Find the certificate inside the list and see if it is properly paired with your private key.

If certificate is not signed with private key, delete it, go to apple developer page and create new certificate. Sometimes it will be needed to revoke old. This new certificate will be now properly signed with your private key.

Now, when you have new certificate, recreate needed provisioning profiles that will include new certificate in creation process.

Note, when somebody from your team reset this certificate with his private key, this same problem can appear again during the refresh process. I am not sure, but it seems that every developer in team must have own certificate for distribution.

Try granting permission to the NETWORK SERVICE user.

proposed solution will not work when a class library with config file is referenced from another project (in my case it was Azure worker project library). It will not copy correct transformed file from obj folder into bin\##configuration-name## folder. To make it work with minimal changes, you need to change AfterCompile target to BeforeCompile:

<Target Name="BeforeCompile" Condition="exists('app.$(Configuration).config')">

$("#save").click(function () {
    debugger
    var xx = [];
    var dd = { "firstname": "", "lastname": "", "address": "" };
    var otable1 = $("#table1").dataTable().fnGetData();

    for (var i = 0; i < otable1.length; i++) {
        dd.firstname = otable1[i][0];
        dd.lastname = otable1[i][1];
        dd.address = otable1[i][2];
        xx.push(dd);
        var dd = { "firstname": "", "lastname": "", "address": "" };
    }
    JSON.stringify(alert(xx));
    $.ajax({

        url: '../Home/save',
        type: 'POST',
        data: JSON.stringify({ u: xx }),
        contentType: 'application/json;',
        dataType: 'json',
        success: function (event) {
            alert(event);
            $("#table2").dataTable().fnDraw();
            location.reload();
        }

You haven't specified how would you like to see these details.

For the first sight I would suggest to check Server Management Studio.

You can see the jobs and current statuses in the SQL Server Agent part, under Jobs. If you pick a job, the Property page shows a link to the Job History, where you can see the start and end time, if there any errors, which step caused the error, and so on.

You can specify alerts and notifications to email you or to page you when the job finished successfully or failed.

There is a Job Activity Monitor, but actually I never used it. You can have a try.

If you want to check it via T-SQL, then I don't know how you can do that.

GoalSeek will throw an "Invalid Reference" error if the GoalSeek cell contains a value rather than a formula or if the ChangingCell contains a formula instead of a value or nothing.

The GoalSeek cell must contain a formula that refers directly or indirectly to the ChangingCell; if the formula doesn't refer to the ChangingCell in some way, GoalSeek either may not converge to an answer or may produce a nonsensical answer.

I tested your code with a different GoalSeek formula than yours (I wasn't quite clear whether some of the terms referred to cells or values).

For the test, I set:

  the GoalSeek cell  H18 = (G18^3)+(3*G18^2)+6
  the Goal cell      H32 =  11
  the ChangingCell   G18 =  0 

The code was:

Sub GSeek()
    With Worksheets("Sheet1")
        .Range("H18").GoalSeek _
        Goal:=.Range("H32").Value, _
        ChangingCell:=.Range("G18")
    End With
End Sub

And the code produced the (correct) answer of 1.1038, the value of G18 at which the formula in H18 produces the value of 11, the goal I was seeking.

Just wait about ten minutes to one hour. If it still doesn't work, contact github. Usually it's the problem at their end. But, if you're in a hurry, you can try to open by adding "?" question mark at the end of URL. It force query to search for the resource. Like this:

http://roine.github.com/p1?

    select 
       @selectoneCount = case @Temp
       when 1 then (@selectoneCount+1)
       when 2 then (@selectoneCount+1)
       end

   select  @selectoneCount 

I found this related question: Directory Listing in S3 Static Website

As it turns out, if you enable public read for the whole bucket, S3 can serve directory listings. Problem is they are in XML instead of HTML, so not very user-friendly.

There are three ways you could go for generating listings:

• Generate index.html files for each directory on your own computer, upload them to s3, and update them whenever you add new files to a directory. Very low-tech. Since you're saying you're uploading build files straight from Travis, this may not be that practical since it would require doing extra work there.

• Use a client-side S3 browser tool.

  • s3-bucket-listing by Rufus Pollock
  • s3-file-list-page by Adam Pritchard

• Use a server-side browser tool.

  • s3browser (PHP)
  • s3index Scala. Going by the existence of a Procfile, it may be readily deployable to Heroku. Not sure since I don't have any experience with Scala.

If you are using a map() operator on your response,you could maybe chain a toArray() operator to it...then you should be able to iterate through newly created array...at least that worked for me :)

httpd -v will give you the version of Apache running on your server (if you have SSH/shell access).

The output should be something like this:

Server version: Apache/2.2.3
Server built:   Oct 20 2011 17:00:12

As has been suggested you can also do apachectl -v which will give you the same output, but will be supported by more flavours of Linux.

I deleted my eclipse.ini after non of the above worked for me.

I fully expected the next run (when it looked likely to work) to recreate it so I could compare but it did not.

So I can't tell what fixed it specifically.

an oddity I did have however was jdk 1.7 but when I ran

C:\Users\jonathan.hardcastle>java -version Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion' has value '1.7', but '1.6' is required. Error: could not find java.dll Error: could not find Java SE Runtime Environment.

i got the above.. so I (re?)installed jre 1.7 specifically and that went away.

This was not linked to my eclipse success directly.

In my case preserve logs do the trick. I did everything to show the logs, but it goes away. I checked it and it works,

Use Object.entries() function.

Object.entries(object) return:

[
    [key, value],
    [key, value],
    ...
]

see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries

{Object.entries(subjects).map(([key, subject], i) => (
    <li className="travelcompany-input" key={i}>
        <span className="input-label">key: {i} Name: {subject.name}</span>
    </li>
))}

You can use the following code to generate a requirements.txt file:

pip install pipreqs

pipreqs /path/to/project

more info related to pipreqs can be found here.

Sometimes you come across pip freeze, but this saves all packages in the environment including those that you don't use in your current project.

Subset is your safest and easiest answer.

subset(dataframe, A==B & E!=0)

Real data example with mtcars

subset(mtcars, cyl==6 & am!=0)

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

I tried the solutions above, but had no luck. I noticed this line in my project's package.json:

 "bin": {
"webpack-dev-server": "bin/webpack-dev-server.js"

},

I looked at bin/webpack-dev-server.js and found this line:

.describe("port", "The port").default("port", 8080)

I changed the port to 3000. A bit of a brute force approach, but it worked for me.

It could be that your code is compiled with x64 therefore have to enable the Default Processor Architecture as X64.

Test > Test Settings > Default Processor Architecture > X64

I found this to be the easiest and the shortest, I however rounded off to zero decimal places:

="1" & ":" & ROUND((A1/B1),0)

Note the spaces before and after &.

What this means is that "1" and ":" are seen as additional non-formula information to the overall formula. The ROUND function rounds off A1/B1 that is the basic formula to 0 decimal places. you can try changing to 1,2,3... decimal places.

I hope I made this clear.

You mean something like this?

<?php

$jsonurl = "http://search.twitter.com/trends.json";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);

foreach ( $json_output->trends as $trend )
{
    echo "{$trend->name}\n";
}

sprintf(mystring, "%05d", myInt);

Here, "05" says "use 5 digits with leading zeros".

In that case you need git credential helper to tell git to remember your GitHub password and username by using following command line :

git config --global credential.helper wincred 

and if you are using repo using SSH key then you need SSH key to authenticate.

A Hamiltonian path visits every node (or vertex) exactly once, and a Eulerian path traverses every edge exactly once.

For a lot of projects, there is actually 0% difference between the different pythons in terms of speed. That is those that are dominated by engineering time and where all pythons have the same amount of library support.

Try using anaconda. I had the same error. One lone option was to build tensorflow from source which took long time. I tried using conda and it worked.

1. Create a new environment in anaconda.
2. conda -c conda-forge tensorflow

Then, it worked.

In our case, nothing was logged (other than the HTTP error log entry for the 503), but the Enabled Protocols value for the web application in IIS had a typo in it! Instead of http,https there was a period in-between the protocols: http.https

    protected override void OnLoad(EventArgs e) {
        base.OnLoad(e);

        CenterToParent();
    }

Or you can just use this simple 2 liner code :)

            button1.PerformClick();

I found this question due the exception mentioned in it. My Web.Config didn't have any <roleManager> tag. I realized that even if I added it (as Infotekka suggested), it ended up in a Database exception. After following the suggestions in the other answers in here, none fully solved the problem.

Since these Web.Config tags can be automatically generated, it felt wrong to solve it by manually adding them. If you are in a similar case, undo all the changes you made to Web.Config and in Visual Studio:

1. Press Ctrl+Q, type nuget and click on "Manage NuGet Packages";
2. Press Ctrl+E, type providers and in the list it should show up "Microsoft ASP.NET Universal Providers Core Libraries" and "Microsoft ASP.NET Universal Providers for LocalDB" (both created by Microsoft);
3. Click on the Install button in both of them and close the NuGet window;

4. Check your Web.config and now you should have at least one <providers> tag inside Profile, Membership, SessionState tags and also inside the new RoleManager tag, like this:

   <roleManager defaultProvider="DefaultRoleProvider">
       <providers>
          <add name="DefaultRoleProvider" type="System.Web.Providers.DefaultRoleProvider, System.Web.Providers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=NUMBER" connectionStringName="DefaultConnection" applicationName="/" />
       </providers>
   </roleManager>
   

5. Add enabled="true" like so:

   <roleManager defaultProvider="DefaultRoleProvider" enabled="true">
   

6. Press F6 to Build and now it should be OK to proceed to a database update without having that exception:

   1. Press Ctrl+Q, type manager, click on "Package Manager Console";
   2. Type update-database -verbose and the Seed method will run just fine (if you haven't messed elsewhere) and create a few tables in your Database;
   3. Press Ctrl+W+L to open the Server Explorer and you should be able to check in Data Connections > DefaultConnection > Tables the Roles and UsersInRoles tables among the newly created tables!

Here is a safe and reusable function for adding script to head section if its not already exist there.

see working example here: Example

<!DOCTYPE html>
<html>
  <head>
    <base href="/"/>
    <style>
    </style>
  </head>
  <body>
    <input type="button" id="" style='width:250px;height:50px;font-size:1.5em;' value="Add Script" onClick="addScript('myscript')"/>
    <script>
      function addScript(filename)
      {
        // house-keeping: if script is allready exist do nothing
        if(document.getElementsByTagName('head')[0].innerHTML.toString().includes(filename + ".js"))
        {
          alert("script is allready exist in head tag!")
        }
        else
        {
          // add the script
          loadScript('/',filename + ".js");
        }
      }
      function loadScript(baseurl,filename)
      {
        var node = document.createElement('script');
        node.src = baseurl + filename;
        document.getElementsByTagName('head')[0].appendChild(node);
        alert("script added");
      }
    </script>
  </body>
</html>

I see many (all) posts above relying on LBound/UBound calls upon yet potentially uninitialized VBA dynamic array, what causes application's inevitable death ...

Erratic code:

Dim x As Long Dim arr1() As SomeType ... x = UBound(arr1) 'crashes

Correct code:

Dim x As Long Dim arr1() As SomeType ... ReDim Preserve arr1(0 To 0) ... x = UBound(arr1)

... i.e. any code where Dim arr1() is followed immediatelly by LBound(arr1)/UBound(arr1) calls without ReDim arr1(...) in between, crashes. The roundabout is to employ an On Error Resume Next and check the Err.Number right after the LBound(arr1)/UBound(arr1) call - it should be 0 if the array is initialized, otherwise non-zero. As there is some VBA built-in misbehavior, the further check of array's limits is needed. Detailed explanation may everybody read at Chip Pearson's website (which should be celebrated as a Mankind Treasure Of VBA Wisdom ...)

Heh, that's my first post, believe it is legible.

npm config set strict-ssl false

If your table is only 2 columns across, you can easily reach the second td with the adjacent sibling selector, which IE8 does support along with :first-child:

.editor td:first-child
{
    width: 150px; 
}

.editor td:first-child + td input,
.editor td:first-child + td textarea
{
    width: 500px;
    padding: 3px 5px 5px 5px;
    border: 1px solid #CCC; 
}

Otherwise, you'll have to use a JS selector library like jQuery, or manually add a class to the last td, as suggested by James Allardice.

You can just set the min-width in the css, for example:

.someClass{min-width: 980px;}

It will not break, nevertheless you will still have the scroll-bar to deal with.

Open your logCat when trying to install the app. Set it to "No Filters". Search for "InstallAppProgress" package identifier. If the install fails you should see an "Installation error code". In my case it was

D/InstallAppProgress: Installation error code: -7

From here you can use this link to find information about your specific error code.

Hello World

I see you're having issues with the social share links. I had a similar issue at some point and found this question, but I don't see a complete answer for it. I hope my javascript resolution from below will help:

I had default sharing links that needed to be modified so that the URL that's being shared will have additional UTM parameters concatenated.

My example will be for the Facebook social share link, but it works for all the possible social sharing network links:

The URL that needed to be shared was:

https://mywebsitesite.com/blog/post-name

The default sharing link looked like:

$facebook_default = "https://www.facebook.com/sharer.php?u=https%3A%2F%2mywebsitesite.com%2Fblog%2Fpost-name%2F&t=hello"

I first DECODED it:

console.log( decodeURIComponent($facebook_default) );
=>
https://www.facebook.com/sharer.php?u=https://mywebsitesite.com/blog/post-name/&t=hello

Then I replaced the URL with the encoded new URL (with the UTM parameters concatenated):

console.log( decodeURIComponent($facebook_default).replace( window.location.href, encodeURIComponent(window.location.href+'?utm_medium=social&utm_source=facebook')) );

=>

https://www.facebook.com/sharer.php?u=https%3A%2F%mywebsitesite.com%2Fblog%2Fpost-name%2F%3Futm_medium%3Dsocial%26utm_source%3Dfacebook&t=2018

That's it!

Complete solution:

$facebook_default = $('a.facebook_default_link').attr('href');

$('a.facebook_default_link').attr( 'href', decodeURIComponent($facebook_default).replace( window.location.href, encodeURIComponent(window.location.href+'?utm_medium=social&utm_source=facebook')) );

Try doing this, there's no special character to concatenate in bash :

mystring="${arg1}12${arg2}endoffile"

explanations

If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that's not what you asked) like in the following example :

mystring="$arg112$arg2endoffile"

The brackets are delimiters for the variables when needed. When not needed, you can use it or not.

another solution

$ arg1=foo
$ arg2=bar
$ mystring="$arg1"
$ mystring+="12"
$ mystring+="$arg2"
$ mystring+="endoffile"
$ echo "$mystring"
foo12barendoffile

See http://mywiki.wooledge.org/BashFAQ/013

You can use .prop() with tagName as the name of the property that you want to get:

$("#elementId").prop('tagName'); 

I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.

this is a generic example let me know if this explains the point i mentioned

CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
    empName VARCHAR2(50);
    empSalary NUMBER(7,2);      
BEGIN
    UPDATE emp
    SET sal = sal + 1000
    WHERE empno = 7499
    RETURNING ename, sal
    INTO empName, empSalary;

    DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
    DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;

Since it appears you are using jQuery, here is a jQuery solution.

$(function() {
    $('#Eframe').on("mousewheel", function() {
        alert($(document).scrollTop());
    });
});

Not much to explain here. If you want, here is the jQuery documentation.

You can use comments like in regular JavaScript:

1 Introduction

[...] TypeScript syntax is a superset of ECMAScript 2015 (ES2015) syntax.

2 Basic Concepts

[...] This document describes the syntactic grammar added by TypeScript [...]

Source: TypeScript Language Specification

The only two mentions of the word "comments" in the spec are:

1 Introduction

[...] TypeScript also provides to JavaScript programmers a system of optional type annotations. These type annotations are like the JSDoc comments found in the Closure system, but in TypeScript they are integrated directly into the language syntax. This integration makes the code more readable and reduces the maintenance cost of synchronizing type annotations with their corresponding variables.

11.1.1 Source Files Dependencies

[...] A comment of the form /// <reference path="..."/> adds a dependency on the source file specified in the path argument. The path is resolved relative to the directory of the containing source file.

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

<?php
  $value = "Hello world";
  $tokens = explode(" ", $value);
  echo $tokens[0];
?>

Just use explode to get every word of the input and output the first element of the resulting array.

Not an answer, but an addendum: I got because running groovysh (Groovy 2.4.13) if JAVA_HOME points to a Java 9 installation (java version "9.0.1" to be precise) fails abysmally:

The solution was to:

• Go to the JAXB Project at github.io ("JAXB is licensed under a dual license - CDDL 1.1 and GPL 2.0 with Class-path Exception")

• Download jaxb-ri-2.3.0.zip

• Unzip wherever you put your java infrastructure files (in my case, /usr/local/java/jaxb-ri/). Other solution may exist (maybe via SDKMAN, I dunno)

• Make sure the jars in the lib subdirectory are on the CLASSPATH. I do it via a script started on bash startup, called /etc/profile.d/java.sh, where I added (among many other lines) the following loop:

Packed into a function...

function extend_qzminynshg {
   local BASE="/usr/local/java"
   for LIB in jaxb-api.jar  jaxb-core.jar  jaxb-impl.jar  jaxb-jxc.jar  jaxb-xjc.jar; do
      local FQLIB="$BASE/jaxb-ri/lib/$LIB"
      if [[ -f $FQLIB ]]; then
         export CLASSPATH=$FQLIB:$CLASSPATH
      fi
    done
}

extend_qzminynshg; unset extend_qzminynshg

And it works!

Trace.Write("Error Message") and Trace.Warn("Error Message") are the methods to use in web, need to decorate the page header trace=true and in config file to hide the error message text to go to end-user and so as to stay in iis itself for programmer debug.

If you have the XML stored inside a string variable you could use a StringReader:

var xml = @"<car/>";
var serializer = new XmlSerializer(typeof(Car));
using (var reader = new StringReader(xml))
{
    var car = (Car)serializer.Deserialize(reader);
}

Making it invisible with visibility still makes it use up space. Rather try set the display to none to make it invisible, and then set the display to block to make it visible.

Use below code for passing string from one jsp to another jsp

A.jsp

   <% String userid="Banda";%>
    <form action="B.jsp" method="post">
    <%
    session.setAttribute("userId", userid);
        %>
        <input type="submit"
                            value="Login">
    </form>

B.jsp

    <%String userid = session.getAttribute("userId").toString(); %>
    Hello<%=userid%>

It also posible string replacement with stringByReplacingCharactersInRange:withString:

for (int i = 0; i < card.length - 4; i++) {

    if (![[card substringWithRange:NSMakeRange(i, 1)] isEqual:@" "]) {

        NSRange range = NSMakeRange(i, 1);
        card = [card stringByReplacingCharactersInRange:range withString:@"*"];

    }
