Event delegation allows you to avoid adding event listeners to specific nodes; instead, the event listener is added to one parent. That event listener analyzes bubbled events to find a match on child elements.

JavaScript Example :

Let's say that we have a parent UL element with several child elements:

<ul id="parent-list">
  <li id="post-1">Item 1</li>
  <li id="post-2">Item 2</li>
  <li id="post-3">Item 3</li>
  <li id="post-4">Item 4</li>
  <li id="post-5">Item 5</li>
  <li id="post-6">Item 6</li>
</ul>

Let's also say that something needs to happen when each child element is clicked. You could add a separate event listener to each individual LI element, but what if LI elements are frequently added and removed from the list? Adding and removing event listeners would be a nightmare, especially if addition and removal code is in different places within your app. The better solution is to add an event listener to the parent UL element. But if you add the event listener to the parent, how will you know which element was clicked?

Simple: when the event bubbles up to the UL element, you check the event object's target property to gain a reference to the actual clicked node. Here's a very basic JavaScript snippet which illustrates event delegation:

// Get the element, add a click listener...
document.getElementById("parent-list").addEventListener("click", function(e) {
  // e.target is the clicked element!
  // If it was a list item
  if(e.target && e.target.nodeName == "LI") {
    // List item found!  Output the ID!
    console.log("List item ", e.target.id.replace("post-"), " was clicked!");
   }
});

Start by adding a click event listener to the parent element. When the event listener is triggered, check the event element to ensure it's the type of element to react to. If it is an LI element, boom: we have what we need! If it's not an element that we want, the event can be ignored. This example is pretty simple -- UL and LI is a straight-forward comparison. Let's try something more difficult. Let's have a parent DIV with many children but all we care about is an A tag with the classA CSS class:

// Get the parent DIV, add click listener...
document.getElementById("myDiv").addEventListener("click",function(e) {
// e.target was the clicked element
  if(e.target && e.target.nodeName == "A") {
    // Get the CSS classes
    var classes = e.target.className.split(" ");
    // Search for the CSS class!
    if(classes) {
        // For every CSS class the element has...
        for(var x = 0; x < classes.length; x++) {
            // If it has the CSS class we want...
            if(classes[x] == "classA") {
                // Bingo!
                console.log("Anchor element clicked!");
                // Now do something here....
            }
        }
    }
  }
});

I use TINYINT(1) in order to store boolean values in Mysql.

I don't know if there is any advantage to use this... But if i'm not wrong, mysql can store boolean (BOOL) and it store it as a tinyint(1)

There is something very important about this thread that has been touched on but not fully explained. The HTML approach (adding a meta tag in the head) only works consistently on raw HTML or very basic server pages. My site is a very complex server-driven site with master pages, themeing and a lot of third party controls, etc. What I found was that some of these controls were programmatically adding their own tags to the final HTML which were being pushed to the browser at the beginning of the head tag. This effectively rendered the HTML meta tags useless.

Well, if you can't beat them, join them. The only solution that worked for me is to do exactly the same thing in the pre-render event of my master pages as such:

Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
    Dim MetaTag As HtmlMeta = New HtmlMeta()
    MetaTag.Attributes("http-equiv") = "Content-Type"
    MetaTag.Attributes("content") = "text/html; charset=utf-8;"
    Page.Header.Controls.AddAt(0, MetaTag)

    MetaTag = New HtmlMeta()
    MetaTag.Attributes("http-equiv") = "X-UA-Compatible"
    MetaTag.Attributes("content") = "IE=9,chrome=1"
    Page.Header.Controls.AddAt(0, MetaTag)
End Sub

This is VB.NET but the same approach would work for any server-side technology. As long as you make sure it's the last thing that gets done right before the page is rendered.

let's take a question: Given two strings s and t, write a function to determine if t is an anagram of s.

For example, s = "anagram", t = "nagaram", return true. s = "rat", t = "car", return false.

Method 1(Using HashMap ):

public class Method1 {

    public static void main(String[] args) {
        String a = "protijayi";
        String b = "jayiproti";
        System.out.println(isAnagram(a, b ));// output => true

    }

    private static boolean isAnagram(String a, String b) {
        Map<Character ,Integer> map = new HashMap<>();
        for( char c : a.toCharArray()) {
            map.put(c,    map.getOrDefault(c, 0 ) + 1 );
        }
        for(char c : b.toCharArray()) {
            int count = map.getOrDefault(c, 0);
            if(count  == 0 ) {return false ; }
            else {map.put(c, count - 1 ) ; }
        }
        
        return true;
    }

}

Method 2 :

public class Method2 {
public static void main(String[] args) {
    String a = "protijayi";
    String b = "jayiproti";

    
    System.out.println(isAnagram(a, b));// output=> true
}

private static boolean isAnagram(String a, String b) {
   
    
    int[] alphabet = new int[26];
    for(int i = 0 ; i < a.length() ;i++) {
         alphabet[a.charAt(i) - 'a']++ ;
    }
    for (int i = 0; i < b.length(); i++) {
         alphabet[b.charAt(i) - 'a']-- ;
    }
    
    for(  int w :  alphabet ) {
         if(w != 0 ) {return false;}
    }
    return true;
    
}
}

Method 3 :

public class Method3 {
public static void main(String[] args) {
    String a = "protijayi";
    String b = "jayiproti";
    
    
    System.out.println(isAnagram(a, b ));// output => true
}

private static boolean isAnagram(String a, String b) {
    char[] ca = a.toCharArray() ;
    char[] cb = b.toCharArray();
    Arrays.sort(   ca     );
    
    Arrays.sort(   cb        );
    return Arrays.equals(ca , cb );
}
}

Method 4 :

public class AnagramsOrNot {
    public static void main(String[] args) {
        String a = "Protijayi";
        String b = "jayiProti";
        isAnagram(a, b);
    }

    private static void isAnagram(String a, String b) {
        Map<Integer, Integer> map = new LinkedHashMap<>();

        a.codePoints().forEach(code -> map.put(code, map.getOrDefault(code, 0) + 1));
        System.out.println(map);
        b.codePoints().forEach(code -> map.put(code, map.getOrDefault(code, 0) - 1));
        System.out.println(map);
        if (map.values().contains(0)) {
            System.out.println("Anagrams");
        } else {
            System.out.println("Not Anagrams");
        }
    }
}

In Python:

def areAnagram(a, b):
    if len(a) != len(b): return False
    count1 = [0] * 256
    count2 = [0] * 256
    for i in a:count1[ord(i)] += 1
    for i in b:count2[ord(i)] += 1

    for i in range(256):
        if(count1[i] != count2[i]):return False    

    return True


str1 = "Giniiii"
str2 = "Protijayi"
print(areAnagram(str1, str2))

Let's take another famous Interview Question: Group the Anagrams from a given String:

public class GroupAnagrams {
    public static void main(String[] args) {
        String a = "Gini Gina Protijayi iGin aGin jayiProti Soudipta";
        Map<String, List<String>> map = Arrays.stream(a.split(" ")).collect(Collectors.groupingBy(GroupAnagrams::sortedString));
        System.out.println("MAP => " + map);
        map.forEach((k,v) -> System.out.println(k +" and the anagrams are =>" + v ));
        /*
         Look at the Map output:
        MAP => {Giin=[Gini, iGin], Paiijorty=[Protijayi, jayiProti], Sadioptu=[Soudipta], Gain=[Gina, aGin]}
        As we can see, there are multiple Lists. Hence, we have to use a flatMap(List::stream)
        Now, Look at the output:
        Paiijorty and the anagrams are =>[Protijayi, jayiProti]
       
        Now, look at this output:
        Sadioptu and the anagrams are =>[Soudipta]
        List contains only word. No anagrams.
        That means we have to work with map.values(). List contains all the anagrams.
        
                     
        */
        String stringFromMapHavingListofLists = map.values().stream().flatMap(List::stream).collect(Collectors.joining(" "));
        System.out.println(stringFromMapHavingListofLists);
    }

    public static String sortedString(String a) {
        String sortedString = a.chars().sorted()
                .collect(StringBuilder::new, StringBuilder::appendCodePoint, StringBuilder::append).toString();

        return sortedString;

    }
    
    /*
     * The output : Gini iGin Protijayi jayiProti Soudipta Gina aGin
     * All the anagrams are side by side.
     */
}

Now to Group Anagrams in Python is again easy.We have to : Sort the lists. Then, Create a dictionary. Now dictionary will tell us where are those anagrams are( Indices of Dictionary). Then values of the dictionary is the actual indices of the anagrams.

def groupAnagrams(words):
 
    # sort each word in the list
    A = [''.join(sorted(word)) for word in words]
    dict = {}
    for indexofsamewords, names in enumerate(A):
     dict.setdefault(names, []).append(indexofsamewords)
    print(dict)
    #{'AOOPR': [0, 2, 5, 11, 13], 'ABTU': [1, 3, 4], 'Sorry': [6], 'adnopr': [7], 'Sadioptu': [8, 16], ' KPaaehiklry': [9], 'Taeggllnouy': [10], 'Leov': [12], 'Paiijorty': [14, 18], 'Paaaikpr': [15], 'Saaaabhmryz': [17], ' CNaachlortttu': [19], 'Saaaaborvz': [20]}
 
    for index in dict.values():
     print([words[i] for i in index])
 

if __name__ == '__main__':
 
    # list of words
    words = ["ROOPA","TABU","OOPAR","BUTA","BUAT" , "PAROO","Soudipta",
        "Kheyali Park", "Tollygaunge", "AROOP","Love","AOORP", "Protijayi","Paikpara","dipSouta","Shyambazaar",
        "jayiProti", "North Calcutta", "Sovabazaar"]
 
    groupAnagrams(words)
 

The Output :

['ROOPA', 'OOPAR', 'PAROO', 'AROOP', 'AOORP']
['TABU', 'BUTA', 'BUAT']
['Soudipta', 'dipSouta']
['Kheyali Park']
['Tollygaunge']
['Love']
['Protijayi', 'jayiProti']
['Paikpara']
['Shyambazaar']
['North Calcutta']
['Sovabazaar']

Another Important Anagram Question : Find the Anagram occuring Max. number of times. In the Example, ROOPA is the word which has occured maximum number of times. Hence, ['ROOPA' 'OOPAR' 'PAROO' 'AROOP' 'AOORP'] will be the final output.

from sqlite3 import collections
from statistics import mode, mean

import numpy as np


# list of words
words = ["ROOPA","TABU","OOPAR","BUTA","BUAT" , "PAROO","Soudipta",
        "Kheyali Park", "Tollygaunge", "AROOP","Love","AOORP",
         "Protijayi","Paikpara","dipSouta","Shyambazaar",
        "jayiProti", "North Calcutta", "Sovabazaar"]

print(".....Method 1....... ")

sortedwords = [''.join(sorted(word)) for word in words]
print(sortedwords)
print("...........")
LongestAnagram = np.array(words)[np.array(sortedwords) == mode(sortedwords)]
# Longest anagram 
print("Longest anagram by Method 1:")
print(LongestAnagram)

print(".....................................................")  

print(".....Method 2....... ")  

A = [''.join(sorted(word)) for word in words]

dict = {}

for indexofsamewords,samewords in  enumerate(A):
    dict.setdefault(samewords,[]).append(samewords)
#print(dict)  
#{'AOOPR': ['AOOPR', 'AOOPR', 'AOOPR', 'AOOPR', 'AOOPR'], 'ABTU': ['ABTU', 'ABTU', 'ABTU'], 'Sadioptu': ['Sadioptu', 'Sadioptu'], ' KPaaehiklry': [' KPaaehiklry'], 'Taeggllnouy': ['Taeggllnouy'], 'Leov': ['Leov'], 'Paiijorty': ['Paiijorty', 'Paiijorty'], 'Paaaikpr': ['Paaaikpr'], 'Saaaabhmryz': ['Saaaabhmryz'], ' CNaachlortttu': [' CNaachlortttu'], 'Saaaaborvz': ['Saaaaborvz']}
     
aa =  max(dict.items() , key = lambda x : len(x[1]))
print("aa => " , aa)    
word, anagrams = aa 
print("Longest anagram by Method 2:")
print(" ".join(anagrams))    

The Output :

.....Method 1....... 
['AOOPR', 'ABTU', 'AOOPR', 'ABTU', 'ABTU', 'AOOPR', 'Sadioptu', ' KPaaehiklry', 'Taeggllnouy', 'AOOPR', 'Leov', 'AOOPR', 'Paiijorty', 'Paaaikpr', 'Sadioptu', 'Saaaabhmryz', 'Paiijorty', ' CNaachlortttu', 'Saaaaborvz']

You can use the CONCAT with CURDATE() to the entire time of the day and then filter by using the BETWEEN in WHERE condition:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE (users.signup_date BETWEEN CONCAT(CURDATE(), ' 00:00:00') AND CONCAT(CURDATE(), ' 23:59:59'))

It could be something like that:

var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

var arrays = [], size = 3;
    
while (a.length > 0)
  arrays.push(a.splice(0, size));

console.log(arrays);

See splice Array's method.

Have you tried:

echo "12|23|11" | awk '{split($0,a,"|"); print a[3],a[2],a[1]}'

If your user has a local folder e.g. Linux, in your users home folder you could create a .my.cnf file and provide the credentials to access the server there. for example:-

[client]
host=localhost
user=yourusername
password=yourpassword or exclude to force entry
database=mygotodb

Mysql would then open this file for each user account read the credentials and open the selected database.

Not sure on Windows, I upgraded from Windows because I needed the whole house not just the windows (aka Linux) a while back.

in javascript, object properties can be accessed with . operator or with associative array indexing using []. ie. object.property is equivalent to object["property"]

this should do the trick

var smth = mydata.list[0]["points.bean.pointsBase"][0].time;

And if you have more than two lists to concatenate:

import operator
from functools import reduce  # For Python 3
list1, list2, list3 = [1,2,3], ['a','b','c'], [7,8,9]
reduce(operator.add, [list1, list2, list3])

# or with an existing list
all_lists = [list1, list2, list3]
reduce(operator.add, all_lists)

It doesn't actually save you any time (intermediate lists are still created) but nice if you have a variable number of lists to flatten, e.g., *args.

The delete[] operator is used to delete arrays. The delete operator is used to delete non-array objects. It calls operator delete[] and operator delete function respectively to delete the memory that the array or non-array object occupied after (eventually) calling the destructors for the array's elements or the non-array object.

The following shows the relations:

typedef int array_type[1];

// create and destroy a int[1]
array_type *a = new array_type;
delete [] a;

// create and destroy an int
int *b = new int;
delete b;

// create and destroy an int[1]
int *c = new int[1];
delete[] c;

// create and destroy an int[1][2]
int (*d)[2] = new int[1][2];
delete [] d;

For the new that creates an array (so, either the new type[] or new applied to an array type construct), the Standard looks for an operator new[] in the array's element type class or in the global scope, and passes the amount of memory requested. It may request more than N * sizeof(ElementType) if it wants (for instance to store the number of elements, so it later when deleting knows how many destructor calls to done). If the class declares an operator new[] that additional to the amount of memory accepts another size_t, that second parameter will receive the number of elements allocated - it may use this for any purpose it wants (debugging, etc...).

For the new that creates a non-array object, it will look for an operator new in the element's class or in the global scope. It passes the amount of memory requested (exactly sizeof(T) always).

For the delete[], it looks into the arrays' element class type and calls their destructors. The operator delete[] function used is the one in the element type's class, or if there is none then in the global scope.

For the delete, if the pointer passed is a base class of the actual object's type, the base class must have a virtual destructor (otherwise, behavior is undefined). If it is not a base class, then the destructor of that class is called, and an operator delete in that class or the global operator delete is used. If a base class was passed, then the actual object type's destructor is called, and the operator delete found in that class is used, or if there is none, a global operator delete is called. If the operator delete in the class has a second parameter of type size_t, it will receive the number of elements to deallocate.

You'll have to find the index of the person in your persons array, then use the array's splice method:

$scope.persons.splice( $scope.persons.indexOf(person), 1 );

Django querysets are lazy. That means a query will hit the database only when you specifically ask for the result.

So until you print or actually use the result of a query you can filter further with no database access.

As you can see below your code only executes one sql query to fetch only the last 10 items.

Pure JS equivalent for jQuery hide()/show() :

function hide(el) {
    el.style.visibility = 'hidden';    
    return el;
}

function show(el) {
    el.style.visibility = 'visible';    
    return el;
}

hide(document.querySelector(".test"));
// hide($('.test')[0])   // usage with jQuery

We use return el due to satisfy fluent interface "desing pattern".

Here is working example.

Below I also provide HIGHLY unrecommended alternative, which is however probably more "close to question" answer:

HTMLElement.prototype.hide = function() {
    this.style.visibility = 'hidden';  
    return this;
}

HTMLElement.prototype.show = function() {
    this.style.visibility = 'visible';  
    return this;
}

document.querySelector(".test1").hide();
// $('.test1')[0].hide();   // usage with jQuery

of course this not implement jQuery 'each' (given in @JamesAllardice answer) because we use pure js here.

Working example is here.

The above code doesnt actually do anything visible - it just calcualtes then dumps the calculation. Is it the code you used, or just an example for this question?

try doing textAreaDoc.insertString(int, String, AttributeSet) at the end?

I know everybody is ethically against this, but I understand there are reasons of practical joking where this is desired. I think Chrome took a solid stance on this by enforcing a mandatory one second separation time between alert messages. This gives the visitor just enough time to close the page or refresh if they're stuck on an annoying prank site.

So to answer your question, it's all a matter of timing. If you alert more than once per second, Chrome will create that checkbox. Here's a simple example of a workaround:

var countdown = 99;
function annoy(){
    if(countdown>0){
        alert(countdown+" bottles of beer on the wall, "+countdown+" bottles of beer! Take one down, pass it around, "+(countdown-1)+" bottles of beer on the wall!");
        countdown--;

        // Time must always be 1000 milliseconds, 999 or less causes the checkbox to appear
        setTimeout(function(){
            annoy();
        }, 1000);
    }
}

// Don't alert right away or Chrome will catch you
setTimeout(function(){
    annoy();
}, 1000);

For Word 2010 and 2013, go to File > Options > Customize Ribbon > Keyboard Shortcuts > All Commands (in left list) > Color: (in right list) -- at this point, you type in the short cut (such as Alt+r) and select the color (such as red). (This actually goes back to 2003 but I don't have that installed to provide the pathway.)

You could do the following:

• Let the shutdown hook set some AtomicBoolean (or volatile boolean) "keepRunning" to false
• (Optionally, .interrupt the working threads if they wait for data in some blocking call)
• Wait for the working threads (executing writeBatch in your case) to finish, by calling the Thread.join() method on the working threads.
• Terminate the program

Some sketchy code:

• Add a static volatile boolean keepRunning = true;

• In run() you change to

  for (int i = 0; i < N && keepRunning; ++i)
      writeBatch(pw, i);
  

• In main() you add:

  final Thread mainThread = Thread.currentThread();
  Runtime.getRuntime().addShutdownHook(new Thread() {
      public void run() {
          keepRunning = false;
          mainThread.join();
      }
  });
  

That's roughly how I do a graceful "reject all clients upon hitting Control-C" in terminal.

From the docs:

When the virtual machine begins its shutdown sequence it will start all registered shutdown hooks in some unspecified order and let them run concurrently. When all the hooks have finished it will then run all uninvoked finalizers if finalization-on-exit has been enabled. Finally, the virtual machine will halt.

That is, a shutdown hook keeps the JVM running until the hook has terminated (returned from the run()-method.

I wrote a regex to help find and replace "&" within an INSERT, I hope that this helps someone.

The trick was to make sure that the "&" was with other text.

Find “(\'[^\']*(?=\&))(\&)([^\']*\')”

Replace “$1' || chr(38) || '$3”

Here is a more complete example of an XML filter (the example above by itself will not work since it just shows a snippet and is missing the <FindBugsFilter> begin and end tags):

<FindBugsFilter>
    <Match>
        <Class name="com.mycompany.foo" />
        <Method name="bar" />
        <Bug pattern="NP_BOOLEAN_RETURN_NULL" />
    </Match>
</FindBugsFilter>

If you are using the Android Studio FindBugs plugin, browse to your XML filter file using File->Other Settings->Default Settings->Other Settings->FindBugs-IDEA->Filter->Exclude filter files->Add.

You can find the list of formats here (in the Double.ToString()-MSDN-Article) as comments in the example section.

The base dn is dc=example,dc=com.

I don't know about openca, but I will try this answer since you got very little traffic so far.

A base dn is the point from where a server will search for users. So I would try to simply use admin as a login name.

If openca behaves like most ldap aware applications, this is what is going to happen :

1. An ldap search for the user admin will be done by the server starting at the base dn (dc=example,dc=com).
2. When the user is found, the full dn (cn=admin,dc=example,dc=com) will be used to bind with the supplied password.
3. The ldap server will hash the password and compare with the stored hash value. If it matches, you're in.

Getting step 1 right is the hardest part, but mostly because we don't get to do it often. Things you have to look out for in your configuraiton file are :

• The dn your application will use to bind to the ldap server. This happens at application startup, before any user comes to authenticate. You will have to supply a full dn, maybe something like cn=admin,dc=example,dc=com.
• The authentication method. It is usually a "simple bind".
• The user search filter. Look at the attribute named objectClass for your admin user. It will be either inetOrgPerson or user. There will be others like top, you can ignore them. In your openca configuration, there should be a string like (objectClass=inetOrgPerson). Whatever it is, make sure it matches your admin user's object Class. You can specify two object class with this search filter (|(objectClass=inetOrgPerson)(objectClass=user)).

Download an LDAP Browser, such as Apache's Directory Studio. Connect using your application's credentials, so you will see what your application sees.

You can improve read speed by using a BufferedStream, like this:

using (FileStream fs = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
using (BufferedStream bs = new BufferedStream(fs))
using (StreamReader sr = new StreamReader(bs))
{
    string line;
    while ((line = sr.ReadLine()) != null)
    {

    }
}

March 2013 UPDATE

I recently wrote code for reading and processing (searching for text in) 1 GB-ish text files (much larger than the files involved here) and achieved a significant performance gain by using a producer/consumer pattern. The producer task read in lines of text using the BufferedStream and handed them off to a separate consumer task that did the searching.

I used this as an opportunity to learn TPL Dataflow, which is very well suited for quickly coding this pattern.

Why BufferedStream is faster

A buffer is a block of bytes in memory used to cache data, thereby reducing the number of calls to the operating system. Buffers improve read and write performance. A buffer can be used for either reading or writing, but never both simultaneously. The Read and Write methods of BufferedStream automatically maintain the buffer.

December 2014 UPDATE: Your Mileage May Vary

Based on the comments, FileStream should be using a BufferedStream internally. At the time this answer was first provided, I measured a significant performance boost by adding a BufferedStream. At the time I was targeting .NET 3.x on a 32-bit platform. Today, targeting .NET 4.5 on a 64-bit platform, I do not see any improvement.

I came across a case where streaming a large, generated CSV file to the Response stream from an ASP.Net MVC action was very slow. Adding a BufferedStream improved performance by 100x in this instance. For more see Unbuffered Output Very Slow

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

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

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

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

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

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

You can join a table to itself as many times as you require, it is called a self join.

An alias is assigned to each instance of the table (as in the example below) to differentiate one from another.

SELECT a.SelfJoinTableID
FROM   dbo.SelfJoinTable a
       INNER JOIN dbo.SelfJoinTable b
         ON a.SelfJoinTableID = b.SelfJoinTableID
       INNER JOIN dbo.SelfJoinTable c
         ON a.SelfJoinTableID = c.SelfJoinTableID
WHERE  a.Status = 'Status to filter a'
       AND b.Status = 'Status to filter b'
       AND c.Status = 'Status to filter c' 

you have to create a instance of the class for calling the method..

This answer is much more specific to Ruby on Rails, but hopefully it will help someone.

You need to include the CSRF token with every non-GET request. If you're used to using JQuery, Rails has a helper library called jquery-ujs that builds on top of it and adds some hidden functionality. One of the things it does is automatically includes the CSRF token in every ajax request. See here.

If you switch away from it like I did you might find yourself with an error. You can just submit the token manually or use another library to help scrape the token from the DOM. See this post for more detail.

def __iter__(self):
    field_names = [f.name for f in self._meta.fields]
    for field_name in field_names:
        value = getattr(self, field_name, None)
        yield (field_name, value)

This worked for me in django==1.11.8

The accepted answer has a bug in it where it still eats the first character of the input string if the delimiter is not found.

$str = '1-2-3-4-5';
echo substr($str, strrpos($str, '-') + 1);

Produces the expected result: 5

$str = '1-2-3-4-5';
echo substr($str, strrpos($str, ';') + 1);

Produces -2-3-4-5

$str = '1-2-3-4-5';
if (($pos = strrpos($str, ';')) !== false)
    echo substr($str, $pos + 1);
else
    echo $str;

Produces the whole string as desired.

You should not wrap JavaScript expressions in quotes.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

The problem comes from the fact that np.isnan() does not handle string values correctly. For example, if you do:

np.isnan("A")
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

However the pandas version pd.isnull() works for numeric and string values:

pd.isnull("A")
> False

pd.isnull(3)
> False

pd.isnull(np.nan)
> True

pd.isnull(None)
> True

This did it for me...

//trim message to 100 characters, regardless of where it cuts off
$msgTrimmed = mb_substr($var,0,100);

//find the index of the last space in the trimmed message
$lastSpace = strrpos($msgTrimmed, ' ', 0);

//now trim the message at the last space so we don't cut it off in the middle of a word
echo mb_substr($msgTrimmed,0,$lastSpace)

Try:

sheet 2 a1 =vlookup(sheet2a1,sheet1$a$1:$b$6,2)

Then drag it down.

It should work.

How about plain JavaScript? More about Array.prototype.filter().

var myArray = [{'id': '73', 'name': 'john'}, {'id': '45', 'name': 'Jass'}]_x000D_
_x000D_
var item73 = myArray.filter(function(item) {_x000D_
  return item.id === '73';_x000D_
})[0];_x000D_
_x000D_
// even nicer with ES6 arrow functions:_x000D_
// var item73 = myArray.filter(i => i.id === '73')[0];_x000D_
_x000D_
console.log(item73); // {"id": "73", "name": "john"}

Just add public properties to the user control.

You can add [Category("MyCategory")] and [Description("A property that controls the wossname")] attributes to make it nicer, but as long as it's a public property it should show up in the property panel.

the easiest way would be

new File(filename).getText()

which means you could just do:

new File(filename).text

select person, language     
from table A     
group by person, language  

will return unique rows

If you declare a DateTime, then the default value is DateTime.MinValue, and hence you have to check it like this:

DateTime dat = new DateTime();

 if (dat==DateTime.MinValue)
 {
     //unassigned
 }

If the DateTime is nullable, well that's a different story:

 DateTime? dat = null;

 if (!dat.HasValue)
 {
     //unassigned
 }

In both examples, you are assigning a new int[10] to a reference variable.

Assigning to a reference variable either way will be equal in performance.

int[] array = new int[10];

The notation above is considered best practice for readability.

I have developed an Excel VBA Macro for cutting and pasting any selection from Excel into SQL Server, creating a new table. The macro is great for quick and dirty table creations up to a few thousand rows and multiple columns (It can theoretically manage up to 200 columns). The macro attempts to automatically detect header names and assign the most appropriate datatype to each column (it handles varchar columns upto 1000 chars).

Recommended Setup procedure:

1. Make sure Excel is enabled to run macros. (File->Options->Trust Center->Trust Center Settings->Macro Settings->Enable all macros..)
2. Copy the VBA code below to the module associated with your personal workbook (So that the Macro will be available for all worksheets)
3. Assign an appropriate keystroke to the macro ( I have assigned Ctrl Shift X)
4. Save your personal workbook

Use of Macro

1. Select the cells in Excel (including column headers if they exist) to be transferred to SQL
2. Press the assigned keyword combination that you have assigned to run the macro
3. Follow the prompts. (Default table name is ##Table)
4. Paste the clipboard contents into a SSMS window and run the generated SQL code. BriFri 238

How do we merge the master branch into the feature branch? Easy:

git checkout feature1
git merge master

There is no point in forcing a fast forward merge here, as it cannot be done. You committed both into the feature branch and the master branch. Fast forward is impossible now.

Have a look at GitFlow. It is a branching model for git that can be followed, and you unconsciously already did. It also is an extension to Git which adds some commands for the new workflow steps that do things automatically which you would otherwise need to do manually.

So what did you do right in your workflow? You have two branches to work with, your feature1 branch is basically the "develop" branch in the GitFlow model.

You created a hotfix branch from master and merged it back. And now you are stuck.

The GitFlow model asks you to merge the hotfix also to the development branch, which is "feature1" in your case.

So the real answer would be:

git checkout feature1
git merge --no-ff hotfix1

This adds all the changes that were made inside the hotfix to the feature branch, but only those changes. They might conflict with other development changes in the branch, but they will not conflict with the master branch should you merge the feature branch back to master eventually.

Be very careful with rebasing. Only rebase if the changes you did stayed local to your repository, e.g. you did not push any branches to some other repository. Rebasing is a great tool for you to arrange your local commits into a useful order before pushing it out into the world, but rebasing afterwards will mess up things for the git beginners like you.

@aku: One example is code reviews. Another example is refactoring scenarios.

Basically I don't want to go type-hunting with my mouse. It might not be available.

For Word Wrapping in Php Storm 2019.1.3 Just follow below steps:

from top nagivation menu

View -> Active Editor -> Soft-Wrap

that's it so simple.

If by "local" you mean on the same network segment, then you have to perform the following steps:

1. Determine your own IP address
2. Determine your own netmask
3. Determine the network range
4. Scan all the addresses (except the lowest, which is your network address and the highest, which is your broadcast address).
5. Use your DNS's reverse lookup to determine the hostname for IP addresses which respond to your scan.

Or you can just let Python execute nmap externally and pipe the results back into your program.

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

It will be bigger in base64.

Base64 uses 6 bits per byte to encode data, whereas binary uses 8 bits per byte. Also, there is a little padding overhead with Base64. Not all bits are used with Base64 because it was developed in the first place to encode binary data on systems that can only correctly process non-binary data.

That means that the encoded image will be around 33%-36% larger (33% from not using 2 of the bits per byte, plus possible padding accounting for the remaining 3%).

I agree with zach that counting within dplyr is the best solution. I've found this to be the shortest version:

dplyr::count(theTable, Position) %>%
          arrange(-n) %>%
          mutate(Position = factor(Position, Position)) %>%
          ggplot(aes(x=Position, y=n)) + geom_bar(stat="identity")

This will also be significantly faster than reordering the factor levels beforehand since the count is done in dplyr not in ggplot or using table.

Autocomplete in Notepad++ is as simple as hitting Ctrl + Enter or Ctrl + Space in the interface.

Ctrl + Enter - as simple as that!

This, for many people, will be better than autocompleting on everything.

According to JavaDocs, you can do this:

WebElement input = divA.findElement(By.xpath(".//input"));

How can I ask in xpath for "the div-tag that contains a span with the text 'hello world'"?

WebElement elem = driver.findElement(By.xpath("//div[span[text()='hello world']]"));

The XPath spec is a suprisingly good read on this.

All you need to do is set "jquery": true in your .jshintrc.

Per the JSHint options reference:

jquery

This option defines globals exposed by the jQuery JavaScript library.

SELECT * FROM Table where codtable not in (Select codtable from Table where fecha is null)

First of all

1. You don't need any special changes in the structure. I mean: html input tags.

<input accept="image/*" name="file" ng-value="fileToUpload"_x000D_
       value="{{fileToUpload}}" file-model="fileToUpload"_x000D_
       set-file-data="fileToUpload = value;" _x000D_
       type="file" id="my_file" />

1.2 create own directive,

.directive("fileModel",function() {_x000D_
 return {_x000D_
  restrict: 'EA',_x000D_
  scope: {_x000D_
   setFileData: "&"_x000D_
  },_x000D_
  link: function(scope, ele, attrs) {_x000D_
   ele.on('change', function() {_x000D_
    scope.$apply(function() {_x000D_
     var val = ele[0].files[0];_x000D_
     scope.setFileData({ value: val });_x000D_
    });_x000D_
   });_x000D_
  }_x000D_
 }_x000D_
})

2. In module with $httpProvider add dependency like ( Accept, Content-Type etc) with multipart/form-data. (Suggestion would be, accept response in json format) For e.g:

$httpProvider.defaults.headers.post['Accept'] = 'application/json, text/javascript'; $httpProvider.defaults.headers.post['Content-Type'] = 'multipart/form-data; charset=utf-8';

3. Then create separate function in controller to handle form submit call. like for e.g below code:

4. In service function handle "responseType" param purposely so that server should not throw "byteerror".

5. transformRequest, to modify request format with attached identity.

6. withCredentials : false, for HTTP authentication information.

in controller:_x000D_
_x000D_
  // code this accordingly, so that your file object _x000D_
  // will be picked up in service call below._x000D_
  fileUpload.uploadFileToUrl(file); _x000D_
_x000D_
_x000D_
in service:_x000D_
_x000D_
  .service('fileUpload', ['$http', 'ajaxService',_x000D_
    function($http, ajaxService) {_x000D_
_x000D_
      this.uploadFileToUrl = function(data) {_x000D_
        var data = {}; //file object _x000D_
_x000D_
        var fd = new FormData();_x000D_
        fd.append('file', data.file);_x000D_
_x000D_
        $http.post("endpoint server path to whom sending file", fd, {_x000D_
            withCredentials: false,_x000D_
            headers: {_x000D_
              'Content-Type': undefined_x000D_
            },_x000D_
            transformRequest: angular.identity,_x000D_
            params: {_x000D_
              fd_x000D_
            },_x000D_
            responseType: "arraybuffer"_x000D_
          })_x000D_
          .then(function(response) {_x000D_
            var data = response.data;_x000D_
            var status = response.status;_x000D_
            console.log(data);_x000D_
_x000D_
            if (status == 200 || status == 202) //do whatever in success_x000D_
            else // handle error in  else if needed _x000D_
          })_x000D_
          .catch(function(error) {_x000D_
            console.log(error.status);_x000D_
_x000D_
            // handle else calls_x000D_
          });_x000D_
      }_x000D_
    }_x000D_
  }])

<script src="//unpkg.com/angular/angular.js"></script>

Here is a little refactoring of your function (it does not use "else" or "elif"):

def function(a):
    if a not in (1, 2):
        a = 3
    print(str(a) + "a")

@ghostdog74: Python 3 requires parentheses for "print".

I also did my own mysql crawler to search some wordpress configuration, was unable to find it in both the interface and database, and database dumps were too heavy and unreadable. I must say I can't do without it now.

It works like the one from @Olivier, but it manages exotic database / table names and is LIKE-joker safe.

<?php

$database = 'database';
$criteria = '*iemblo'; // you can use * and ? as jokers

$dbh = new PDO("mysql:host=127.0.0.1;dbname={$database};charset=utf8", 'root', '');
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$tables = $dbh->query("SHOW TABLES");
while (($table = $tables->fetch(PDO::FETCH_NUM)) !== false)
{
    $fields = $dbh->prepare("SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = ? AND TABLE_NAME = ?");
    $fields->execute(array ($database, $table[0]));

    $ors = array ();
    while (($field = $fields->fetch(PDO::FETCH_NUM)) !== false)
    {
        $ors[] = str_replace("`", "``", $field[0]) . " LIKE REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(:search, '\\\\', '\\\\\\\\'), '%', '\\%'), '_', '\\_'), '*', '%'), '?', '_')";
    }

    $request = 'SELECT * FROM ';
    $request .= str_replace("`", "``", $table[0]);
    $request .= ' WHERE ';
    $request .= implode(' OR ', $ors);
    $rows = $dbh->prepare($request);

    $rows->execute(array ('search' => $criteria));

    $count = $rows->rowCount();
    if ($count == 0)
    {
        continue;
    }

    $str = "Table '{$table[0]}' contains {$count} rows matching '{$criteria}'.";
    echo str_repeat('-', strlen($str)), PHP_EOL;
    echo $str, PHP_EOL;
    echo str_repeat('-', strlen($str)), PHP_EOL;

    $counter = 1;
    while (($row = $rows->fetch(PDO::FETCH_ASSOC)) !== false)
    {
        $col = 0;
        $title = "Row #{$counter}:";
        echo $title;
        foreach ($row as $column => $value)
        {
            echo
            (($col++ > 0) ? str_repeat(' ', strlen($title) + 1) : ' '),
            $column, ': ',
            trim(preg_replace('!\s+!', ' ', str_replace(array ("\r", "\t", "\n"), array ("", "", " "), $value))),
            PHP_EOL;
        }
        echo PHP_EOL;
        $counter++;
    }
}

Running this script could output something like:

---------------------------------------------------
Table 'customers' contains 1 rows matching '*iemblo'.
---------------------------------------------------

I think that @Benny Neugebauer comment on the OP question about the Fetch API should be presented here as an answer since the OP was looking for a functionality in Chrome to manually create HTTP POST requests and that exactly what the fetch command do.

There is a nice simple example of the Fetch API here

// Make sure you run it from the domain 'https://jsonplaceholder.typicode.com/'. (cross-origin-policy)
fetch('https://jsonplaceholder.typicode.com/posts',{method: 'POST', headers: {'test': 'TestPost'} })
  .then(response => response.json())
  .then(json => console.log(json))

Some of the advantages of the fetch command are really precious: Its simple, short, fast, available and even as a console command it stored on your chrome console and can be used later.

The simplicity of pressing F12, write the command in the console tab (or press the up key if you used it before) then press enter, see it pending and returning the response is what making it really useful for simple post requests tests.

Of course, The main disadvantage here is that unlike Postman, This wont pass the cross-origin-policy but still I find it very useful for testing in local environment or other environments where I can enable CORS manually.

pbcopy is built in OSX:

Copying the content of .bash_profile:

cat ~/.bash_profile | pbcopy

I'd have put this in as a comment as I'm really not certain that this is likely to be the case, but as I recall it doesn't a try/except statement involve a modification to the way the garbage disposal mechanism of the compiler works, in that it clears up object memory allocations in a recursive way off the stack. There may not be an object to be cleared up in this case or the for loop may constitute a closure that the garbage collection mechanism recognises sufficient to enforce a different collection method. Probably not, but I thought it worth a mention as I hadn't seen it discussed anywhere else.

I was running into a similar error in pywikipediabot. The .decode method is a step in the right direction but for me it didn't work without adding 'ignore':

ignore_encoding = lambda s: s.decode('utf8', 'ignore')

Ignoring encoding errors can lead to data loss or produce incorrect output. But if you just want to get it done and the details aren't very important this can be a good way to move faster.

My problem was I was creating the route first

// ...
router.get('/post/data', myController.postHandler);
// ...

and registering the middleware after the route

app.use(bodyParser.json());
//etc

due to app structure & copy and pasting the project together from examples.

Once I fixed the order to register middleware before the route, it all worked.

Else you can get id of process your application runs in:

final static int android.os.Process.myPid()
Returns the identifier of this process, which can be used with killProcess(int) and sendSignal(int, int).

C# in .NET 3.5 using System.DirectoryServices.AccountManagement.

 bool valid = false;
 using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
 {
     valid = context.ValidateCredentials( username, password );
 }

This will validate against the current domain. Check out the parameterized PrincipalContext constructor for other options.

If you use vue cli with the Webpack template (default config), you can create and add your environment variables to a .env file.

The variables will automatically be accessible under process.env.variableName in your project. Loaded variables are also available to all vue-cli-service commands, plugins and dependencies.

You have a few options, this is from the Environment Variables and Modes documentation:

.env                # loaded in all cases
.env.local          # loaded in all cases, ignored by git
.env.[mode]         # only loaded in specified mode
.env.[mode].local   # only loaded in specified mode, ignored by git

Your .env file should look like this:

VUE_APP_MY_ENV_VARIABLE=value
VUE_APP_ANOTHER_VARIABLE=value

It is my understanding that all you need to do is create the .env file and add your variables then you're ready to go! :)

As noted in comment below: If you are using Vue cli 3, only variables that start with VUE_APP_ will be loaded.

Don't forget to restart serve if it is currently running.

The below method is the implementation of binary divide considering both numbers are positive. If subtraction is a concern we can implement that as well using binary operators.

Code

-(int)binaryDivide:(int)numerator with:(int)denominator
{
    if (numerator == 0 || denominator == 1) {
        return numerator;
    }

    if (denominator == 0) {

        #ifdef DEBUG
            NSAssert(denominator==0, @"denominator should be greater then 0");
        #endif
        return INFINITY;
    }

    // if (numerator <0) {
    //     numerator = abs(numerator);
    // }

    int maxBitDenom = [self getMaxBit:denominator];
    int maxBitNumerator = [self getMaxBit:numerator];
    int msbNumber = [self getMSB:maxBitDenom ofNumber:numerator];

    int qoutient = 0;

    int subResult = 0;

    int remainingBits = maxBitNumerator-maxBitDenom;

    if (msbNumber >= denominator) {
        qoutient |=1;
        subResult = msbNumber - denominator;
    }
    else {
        subResult = msbNumber;
    }

    while (remainingBits > 0) {
        int msbBit = (numerator & (1 << (remainingBits-1)))>0?1:0;
        subResult = (subResult << 1) | msbBit;
        if(subResult >= denominator) {
            subResult = subResult - denominator;
            qoutient= (qoutient << 1) | 1;
        }
        else{
            qoutient = qoutient << 1;
        }
        remainingBits--;

    }
    return qoutient;
}

-(int)getMaxBit:(int)inputNumber
{
    int maxBit = 0;
    BOOL isMaxBitSet = NO;
    for (int i=0; i<sizeof(inputNumber)*8; i++) {
        if (inputNumber & (1<<i)) {
            maxBit = i;
            isMaxBitSet=YES;
        }
    }
    if (isMaxBitSet) {
        maxBit+=1;
    }
    return maxBit;
}


-(int)getMSB:(int)bits ofNumber:(int)number
{
    int numbeMaxBit = [self getMaxBit:number];
    return number >> (numbeMaxBit - bits);
}

For multiplication:

-(int)multiplyNumber:(int)num1 withNumber:(int)num2
{
    int mulResult = 0;
    int ithBit;

    BOOL isNegativeSign = (num1<0 && num2>0) || (num1>0 && num2<0);
    num1 = abs(num1);
    num2 = abs(num2);


    for (int i=0; i<sizeof(num2)*8; i++)
    {
        ithBit =  num2 & (1<<i);
        if (ithBit>0) {
            mulResult += (num1 << i);
        }

    }

    if (isNegativeSign) {
        mulResult =  ((~mulResult)+1);
    }

    return mulResult;
}

I got this error when tried to create folder http://localhost:8080/repository/default/parent/newFolder when http://localhost:8080/repository/default/parent didn't exist.

easiest way is

${string:position:length}

Where this extracts $length substring from $string at $position.

This is a bash builtin so awk or sed is not required.

It sounds like you have file in the git repo owned by root. Since you're ssh'ing in as 'username' to do the push, the files must be writable by username. The easiest thing is probably to create the repo as the user, and use the same user to do your pushes. Another option is to create a group, make everything writable by the group, and make your user a member of that group.

The following expresses the experience I had with hibernate 4.0.0.Final.

The javadoc (distributed under LGPL license) of org.hibernate.cfg.Configuration class states that:

NOTE : This will be replaced by use of ServiceRegistryBuilder and org.hibernate.metamodel.MetadataSources instead after the 4.0 release at which point this class will become deprecated and scheduled for removal in 5.0. See HHH-6183, HHH-2578 and HHH-6586 for details

After looking at issue 2578, i used something like this:

ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().configure().buildServiceRegistry();
MetadataSources metadataSources = new MetadataSources(serviceRegistry);
metadataSources.addResource("some_mapping.hbm.xml")
SessionFactory sessionFactory = metadataSources.buildMetadata().buildSessionFactory();

For it to start reading configuration, i had to modify my hibernate 3.2.6 configuration and mapping files to use xmlns="http://www.hibernate.org/xsd/hibernate-configuration" and xmlns="http://www.hibernate.org/xsd/hibernate-mapping" and also remove the dtd specifications.

I couldn't find a way for it to inspect mappings defined in hibernate.cfg.xml and hibernate. prefix for hibernate-related properties in hibernate.cfg.xml is no longer optional.

This might work for some.

I, for one, ran into some error because mapping files contained <cache usage="read-write" /> and ended up using deprecated Configuration way:

Configuration configuration = new Configuration().configure();
SessionFactoryImpl sessionFactory = (SessionFactoryImpl) configuration.buildSessionFactory();
EventListenerRegistry listenerRegistry = sessionFactory.getServiceRegistry().getService(EventListenerRegistry.class);
SolrIndexEventListener indexListener = new SolrIndexEventListener(); // a SaveOrUpdateEventListener i wanted to attach
listenerRegistry.appendListeners(EventType.SAVE_UPDATE, indexListener);

I had to programatically append event listeners because Configuration no longer looks for them in hibernate.cfg.xml

I can run on my device at last, just I enabled the "USB debugging" and "Allow mock location" options from the Debug Menu of my device.

This should solve your problem:

select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);

Give a look also as this SQL Fiddle for test.

In my fairly complex scenario the accepted answer for how to do this in Chrome doesn't work for me. You may want to try the Firefox debugger instead (part of the Firefox developer tools), which shows all of the 'Sources', including those that are part of an iFrame

Below command will push all the branches(including the ones which you have never checked-out but present in your git repo, you can see them by git branch -a)

git push origin '*:*'

NOTE: This command comes handy when you are migrating version control service(i.e migrating from Gitlab to GitHub)

Try this in a Terminal Emulator as root:

restorecon -v -R /data/media

I think this happens due to auto-boxing.

int i = 3;
Object o = i;
o.getClass().getName(); // prints Integer

You may implement a utility method that matches these specific boxing classes and gives you if a certain class is primitive.

public static boolean isWrapperType(Class<?> clazz) {
    return clazz.equals(Boolean.class) || 
        clazz.equals(Integer.class) ||
        clazz.equals(Character.class) ||
        clazz.equals(Byte.class) ||
        clazz.equals(Short.class) ||
        clazz.equals(Double.class) ||
        clazz.equals(Long.class) ||
        clazz.equals(Float.class);
}

You were just adding the html string. Not the element you created with a click event listener.

Try This:

<html>
<head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
</head>
<body>
    <table id="addNodeTable">
        <tr>
            <td>
                Row 1
            </td>
        </tr>
        <tr >
            <td>
                Row 2
            </td>
        </tr>
    </table>
</body>
</html>
<script type="text/javascript">
    $(document).ready(function() {
        var test = $('<button>Test</button>').click(function () {
            alert('hi');
        });
        $("#addNodeTable tr:last").append('<tr><td></td></tr>').find("td:last").append(test);

    });
</script>

Once you have updated the Start in: field make sure to remove the --cd-to-home at the end of the Target: field

If you are already using Spring Boot, argument parsing comes out of the box.

If you want to run something after startup, implement the ApplicationRunner interface:

@SpringBootApplication
public class Application implements ApplicationRunner {

  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }

  @Override
  public void run(ApplicationArguments args) {
    args.containsOption("my-flag-option"); // test if --my-flag-option was set
    args.getOptionValues("my-option");     // returns values of --my-option=value1 --my-option=value2 
    args.getOptionNames();                 // returns a list of all available options
    // do something with your args
  }
}

Your run method will be invoked after the context has started up successfully.

If you need access to the arguments before you fire up your application context, you can just simply parse the application arguments manually:

@SpringBootApplication
public class Application implements ApplicationRunner {

  public static void main(String[] args) {
    ApplicationArguments arguments = new DefaultApplicationArguments(args);
    // do whatever you like with your arguments
    // see above ...
    SpringApplication.run(Application.class, args);
  }

}

And finally, if you need access to your arguments in a bean, just inject the ApplicationArguments:

@Component
public class MyBean {

   @Autowired
   private ApplicationArguments arguments;

   // ...
}

Likewise, here's a 2nd caveat to @Artif3x elaboration of @max-malysh's excellent answer, both above.

With any delayed application of transactions from the master the follower(s) will have an older, stale view of the data. Therefore while providing time for the query on the follower to finish by setting max_standby_archive_delay and max_standby_streaming_delay makes sense, keep both of these caveats in mind:

• the value of the follower as a standby / backup diminishes
• any other queries running on the follower may return stale data.

If the value of the follower for backup ends up being too much in conflict with hosting queries, one solution would be multiple followers, each optimized for one or the other.

Also, note that several queries in a row can cause the application of wal entries to keep being delayed. So when choosing the new values, it’s not just the time for a single query, but a moving window that starts whenever a conflicting query starts, and ends when the wal entry is finally applied.

Use find with a wildcard:

find . -name 'mystring*'

Highlighting the difference between two DataFrames

It is possible to use the DataFrame style property to highlight the background color of the cells where there is a difference.

Using the example data from the original question

The first step is to concatenate the DataFrames horizontally with the concat function and distinguish each frame with the keys parameter:

df_all = pd.concat([df.set_index('id'), df2.set_index('id')], 
                   axis='columns', keys=['First', 'Second'])
df_all

It's probably easier to swap the column levels and put the same column names next to each other:

df_final = df_all.swaplevel(axis='columns')[df.columns[1:]]
df_final

Now, its much easier to spot the differences in the frames. But, we can go further and use the style property to highlight the cells that are different. We define a custom function to do this which you can see in this part of the documentation.

def highlight_diff(data, color='yellow'):
    attr = 'background-color: {}'.format(color)
    other = data.xs('First', axis='columns', level=-1)
    return pd.DataFrame(np.where(data.ne(other, level=0), attr, ''),
                        index=data.index, columns=data.columns)

df_final.style.apply(highlight_diff, axis=None)

This will highlight cells that both have missing values. You can either fill them or provide extra logic so that they don't get highlighted.

I have tried your code in above code don't use [preferences.load(configFile);] statement and it will work.here is running sample code

public static void main(String[]s)
{

    Logger log = Logger.getLogger("MyClass");
    try {
    FileInputStream fis =  new FileInputStream("p.properties");
    LogManager.getLogManager().readConfiguration(fis);
    log.setLevel(Level.FINE);
    log.addHandler(new java.util.logging.ConsoleHandler());
    log.setUseParentHandlers(false);

    log.info("starting myApp");
    fis.close();

    } 
    catch(IOException e) {
    e.printStackTrace();
    }
}

Check out this one, it's open source http://amateras.sourceforge.jp/cgi-bin/fswiki_en/wiki.cgi?page=EclipseHTMLEditor

You can also remove rows and columns by feeding a vector of logical boolean values to the matrix. This handles the situation where you have multiple non-contiguous rows or non-contiguous columns that need to be deleted.

# TRUE = Keep a row/column
# FALSE = Delete a row/column
#
# FALSE for rows 4, 5, and 6
# Row:            1     2     3     4      5      6      7     8     9     10
rows_to_keep <- c(TRUE, TRUE, TRUE, FALSE, FALSE, FALSE, TRUE, TRUE, TRUE, TRUE)
    
# FALSE for columns 7, 8, and 9
# Column:         1     2     3     4     5     6     7      8      9      10
cols_to_keep <- c(TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, FALSE, FALSE, FALSE, TRUE) 

To remove just the rows:

t1 <- t1[rows_to_keep,]

To remove just the columns:

t1 <- t1[,cols_to_keep]

To remove both the rows and columns:

t1 <- t1[rows_to_keep, cols_to_keep]

This coding technique is useful if you don't know in advance what rows or columns you need to remove. The rows_to_keep and cols_to_keep vectors can be calculated as appropriate by your code.

I am Using this

String timeStamp = new SimpleDateFormat("dd/MM/yyyy_HH:mm:ss").format(Calendar.getInstance().getTime());
System.out.println(timeStamp);

In case others have a hard time making sense of this, I think it might help to explain it in very straightforward terms. If you have a variable that you don't use, for example a function for which you've commented out the invocation (a common use-case):

myFn := func () { }
// myFn()

You can assign a useless/blank variable to the function so that it's no longer unused:

myFn := func () { }
_ = myFn
// myFn()

You can simply assign it a new value as follows,

window.location.hash

Flow allows interface specification, without having to convert your whole code base to TypeScript.

Interfaces are a way of breaking dependencies, while stepping cautiously within existing code.

Suppose you have TextBox with Id txtName

$("[id*=txtName]").on('keydown', function(e) { 
  var keyCode = e.keyCode || e.which; 
  if (keyCode == 9) {
     e.preventDefault();
     alert('Tab Pressed');
 }
}); 

Traditionally, if you only want to change the variable in your terminal windows, set it in .bashrc file, which is sourced each time a new terminal is opened. .profile file is not sourced each time you open a new terminal.

See the difference between .profile and .bashrc in question: What's the difference between .bashrc, .bash_profile, and .environment?

.bashrc should solve your problem. However, it is not the proper solution since you are using Ubuntu. See the relevant Ubuntu help page "Session-wide environment variables". Thus, no wonder that .profile does not work for you. I use Ubuntu 12.04 and xfce. I set up my .profile and it is simply not taking effect even if I log out and in. Similar experience here. So you may have to use .pam_environment file and totally forget about .profile, and .bashrc. And NOTE that .pam_environment is not a script file.

You can use function colSums() to calculate sum of all values. [,-1] ensures that first column with names of people is excluded.

 colSums(people[,-1])
Height Weight 
   199    425

Assuming there could be multiple columns that are not numeric, or that your column order is not fixed, a more general approach would be:

colSums(Filter(is.numeric, people))

I tried this:

python -m pipenv # for python2

python3 -m pipenv # for python3

Hope this can help you.

You need to iterate over your ResultSet calling next().

This is an example from java2s.com:

DatabaseMetaData md = conn.getMetaData();
ResultSet rs = md.getTables(null, null, "%", null);
while (rs.next()) {
  System.out.println(rs.getString(3));
}

Column 3 is the TABLE_NAME (see documentation of DatabaseMetaData::getTables).

This is really old, but <font size="10"> would be about <p style= "font-size:55px">

This is an extension of Joey's answer to include the time and pad the parts with 0's.

For example, the result will be 2019-06-01_17-25-36. Also note that this is the UTC time.

  for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %%x

  set Month=0%Month%
  set Month=%Month:~-2%
  set Day=0%Day%
  set Day=%Day:~-2%
  set Hour=0%Hour%
  set Hour=%Hour:~-2%
  set Minute=0%Minute%
  set Minute=%Minute:~-2%
  set Second=0%Second%
  set Second=%Second:~-2%

  set TimeStamp=%Year%-%Month%-%Day%_%Hour%-%Minute%-%Second%

Truely platform-indpendent would be also this R-onliner

readlink(){ RScript -e "cat(normalizePath(commandArgs(T)[1]))" "$1";}

To actually mimic readlink -f <path>, $2 instead of $1 would need to be used.

You can use the -notmatch operator to get the lines that don't have the characters you are interested in.

     Get-Content $FileName | foreach-object { 
     if ($_ -notmatch $arrayofStringsNotInterestedIn) { $) }

@Webgr partial answer actually helped me debug this warning @ console log, shame the other part of that answer brought so many downvotes :(

Anyway, here is how I found out what was the cause of this warning in my case:

1. Use Chrome Browser > Hit F12 to bring DevTools
2. Open the drawer menu (in Chrome 3 vertical dots in the upper right)
3. Under Console > check Log XMLHttpRequests option
4. Reload your page that was giving you the error and observe what happens on each ajax request in the console log.

In my case, another plugin was loading 2 .js libraries after each ajax call, that were absolutely not required nor necessary. Disabling the rogue plugin removed the warning from the log. From that point, you can either try to fix the problem yourself (e.g. limit the loading of the scripts to certain pages or events - this is way too specific for an answer here) or contact 3rd party plugin developer to solve it.

Hope this helps someone.

As @epascarello mentioned for W3C standard browsers, you should use:

body.addEventListener("load", init, false);

However, if you want it to work on IE<9 as well you can use:

var prefix = window.addEventListener ? "" : "on";
var eventName = window.addEventListener ? "addEventListener" : "attachEvent";
document.body[eventName](prefix + "load", init, false);

Or if you want it in a single line:

document.body[window.addEventListener ? 'addEventListener' : 'attachEvent'](
    window.addEventListener ? "load" : "onload", init, false);

Note: here I get a straight reference to the body element via the document, saving the need for the first line.

Also, if you're using jQuery, and you want to use the DOM ready event rather than when the body loads, the answer can be even shorter...

$(init);

ZoneId here = ZoneId.of("Europe/Kiev");
ZonedDateTime hereAndNow = Instant.now().atZone(here);
String.format("%tz", hereAndNow);

will give you a standardized string representation like "+0300"

Please note that there is a mistake in the url provided in this answer:

These steps are working on CentOS 6.5 so they should work on CentOS 7 too:

(EDIT - exactly the same steps work for MariaDB 10.3 on CentOS 8)

1. yum remove mariadb mariadb-server
2. rm -rf /var/lib/mysql If your datadir in /etc/my.cnf points to a different directory, remove that directory instead of /var/lib/mysql
3. rm /etc/my.cnf the file might have already been deleted at step 1
4. Optional step: rm ~/.my.cnf
5. yum install mariadb mariadb-server

[EDIT] - Update for MariaDB 10.1 on CentOS 7

The steps above worked for CentOS 6.5 and MariaDB 10.

I've just installed MariaDB 10.1 on CentOS 7 and some of the steps are slightly different.

Step 1 would become:

yum remove MariaDB-server MariaDB-client

Step 5 would become:

yum install MariaDB-server MariaDB-client

The other steps remain the same.

There are three states of button

• Normal : You can select like this button
• Hover : You can select like this button:hover
• Pressed/Clicked : You can select like this button:active

Normal:

.button
 {
     //your css
 }

Active

 .button:active
{
        //your css
}

Hover

 .button:hover
{
        //your css
}

SNIPPET:

Use :active to style the active state of button.

button:active{_x000D_
   background-color:red;_x000D_
}

<button>Click Me</button>

You just use an ImageButton and make the background whatever you want and set the icon as the src.

<ImageButton
    android:id="@+id/ImageButton01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/album_icon"
    android:background="@drawable/round_button" />

If nothing works try Import app folder not the Git root while opening Android Project and Error will be gone

From Files and Filegroups Architecture

Secondary data files

Secondary data files make up all the data files, other than the primary data file. Some databases may not have any secondary data files, while others have several secondary data files. The recommended file name extension for secondary data files is .ndf.

Also from file extension NDF - Microsoft SQL Server secondary data file

See Understanding Files and Filegroups

Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.

The recommended file name extension for secondary data files is .ndf.

/

For example, three files, Data1.ndf, Data2.ndf, and Data3.ndf, can be created on three disk drives, respectively, and assigned to the filegroup fgroup1. A table can then be created specifically on the filegroup fgroup1. Queries for data from the table will be spread across the three disks; this will improve performance. The same performance improvement can be accomplished by using a single file created on a RAID (redundant array of independent disks) stripe set. However, files and filegroups let you easily add new files to new disks.

It's easy to do, but hard to remember the correct spelling:

pip install mysqlclient

If you need 1.2.x versions (legacy Python only), use pip install MySQL-python

Note: Some dependencies might have to be in place when running the above command. Some hints on how to install these on various platforms:

Ubuntu 14, Ubuntu 16, Debian 8.6 (jessie)

sudo apt-get install python-pip python-dev libmysqlclient-dev

Fedora 24:

sudo dnf install python python-devel mysql-devel redhat-rpm-config gcc

Mac OS

brew install mysql-connector-c

if that fails, try

brew install mysql

If you create a new repository from the Github web GUI, you sometimes get the name 'main' instead of 'master'. By using the command git status from your terminal you'd see which location you are. In some cases, you'd see origin/main.

If you are trying to push your app to a cloud service via CLI then use 'main', not 'master'.

example: git push heroku main

Adding to what was already said.

if you want to *ngFor an element , and hide \ show elements in it, on hover, like you added in the comments, you should re-think the whole concept.

a more appropriate way to do it, does not involve angular at all. I would go with pure CSS instead, using its native :hover property.

something like:

App.Component.css

div span.only-show-on-hover {
    visibility: hidden;
}
div:hover span.only-show-on-hover  {
    visibility: visible;
}

App.Component.html

  <div *ngFor="let i of [1,2,3,4]" > hover me please.
    <span class="only-show-on-hover">you only see me when hovering</span>
  </div>

added a demo: https://stackblitz.com/edit/hello-angular-6-hvgx7n?file=src%2Fapp%2Fapp.component.html

This is what has to occur.

You have to copy your DLL that you want to Register to: c:\windows\SysWOW64\

Then in the Run dialog, type this in: C:\Windows\SysWOW64\regsvr32.exe c:\windows\system32\YourDLL.dll

and you will get the message:

DllRegisterServer in c:\windows\system32\YourDLL.dll succeeded.

In my case the conversion error was in functional based index, that I had created for the table.

The data being inserted was OK. It took me a while to figure out that the actual error came from the buggy index.

Would be nice, if Oracle could have gave more precise error message in this case.

a=123
if [ `echo $a | tr -d [:digit:] | wc -w` -eq 0 ]
then
    echo numeric
else
    echo ng
fi

numeric

a=12s3
if [ `echo $a | tr -d [:digit:] | wc -w` -eq 0 ]
then
    echo numeric
else
    echo ng
fi

ng

I got the same issue and after a lot of time spent on the search I found the solution

I hope will do the same for you!

I use this on a daily basis to show history with files that changed:

git log --stat --pretty=short --graph

To keep it short, add an alias in your .gitconfig by doing:

git config --global alias.ls 'log --stat --pretty=short --graph'

Making HTML5 widgets tha look like iphone widgets is one thing, but making them perform equally well is another matter altogether. Performance of html5 animations (even plain View Transitions), scrolling long lists, responsiveness to gestures feel sticky and jerky. An iPhone user will notice the difference.

There's also some differences in the kinds of gestures that are supported by different devices which results in platform specific code and usability issues as well.

I'll stay with native apps for now I guess.

Note: I'm assuming Windows batch files as most people seem to be unaware that there are significant differences and just blindly call everything with grey text on black background DOS. Nevertheless, the first variant should work in DOS as well.

Executable configuration

The easiest way to do this is to just put the variables in a batch file themselves, each with its own set statement:

set var1=value1
set var2=value2
...

and in your main batch:

call config.cmd

Of course, that also enables variables to be created conditionally or depending on aspects of the system, so it's pretty versatile. However, arbitrary code can run there and if there is a syntax error, then your main batch will exit too. In the UNIX world this seems to be fairly common, especially for shells. And if you think about it, autoexec.bat is nothing else.

Key/value pairs

Another way would be some kind of var=value pairs in the configuration file:

var1=value1
var2=value2
...

You can then use the following snippet to load them:

for /f "delims=" %%x in (config.txt) do (set "%%x")

This utilizes a similar trick as before, namely just using set on each line. The quotes are there to escape things like <, >, &, |. However, they will themselves break when quotes are used in the input. Also you always need to be careful when further processing data in variables stored with such characters.

Generally, automatically escaping arbitrary input to cause no headaches or problems in batch files seems pretty impossible to me. At least I didn't find a way to do so yet. Of course, with the first solution you're pushing that responsibility to the one writing the config file.

If you mean, you want to scroll through multiple items in your stackpanel, try putting a grid around it. By definition, a stackpanel has infinite length.

So try something like this:

   <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Width="311">
              <TextBlock Text="{Binding A}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}" FontStretch="Condensed" FontSize="28" />
              <TextBlock Text="{Binding B}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
        </StackPanel>
    </Grid>

You could even make this work with a ScrollViewer

To answer the WHY in your question:

Because the equality operator can only be applied to simple variable types, such as floats, ints, or chars, and not to more sophisticated types, such as structures or arrays. To determine if two strings are equal, you must explicitly compare the two character strings character by character.

Use below code:

String html = "<a href=\"http://yourdomain.com\">Your Domain Name</a>"
TextView textview = (TextView) findViewById(R.id.your_textview_id);
textview.setMovementMethod(LinkMovementMethod.getInstance());
textview.setText(Html.fromHtml(html));

I think that what you have written is perfectly fine. I also don't see any readability issue with having multiple return statements.

I would always prefer to return from the point in the code when I know to return and this will avoid running logic below the return.

There can be an argument for having a single return point for debugging and logging. But, in your code, there is no issue of debugging and logging if we use it. It is very simple and readable the way you wrote.

I ran into this same issue trying to install the dbf package in Python 2.7. The problem is that the enum package wasn't added to Python until version 3.4.

It has been backported to versions 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4, you just need the package from here: https://pypi.python.org/pypi/enum34#downloads

The setHours method can take optional minutes, seconds and ms arguments, for example:

var d = new Date();
d.setHours(0,0,0,0);

That will set the time to 00:00:00.000 of your current timezone, if you want to work in UTC time, you can use the setUTCHours method.

This worked for me:

var backgroundColor = window.getComputedStyle ? window.getComputedStyle(myDiv, null).getPropertyValue("background-color") : myDiv.style.backgroundColor;

And, even better:

var getStyle = function(element, property) {
    return window.getComputedStyle ? window.getComputedStyle(element, null).getPropertyValue(property) : element.style[property.replace(/-([a-z])/g, function (g) { return g[1].toUpperCase(); })];
};
var backgroundColor = getStyle(myDiv, "background-color");

You can use this query to do the above task:

DECLARE @test NVARCHAR(max)  
SELECT @test = COALESCE(@test + ',', '') + field2 FROM #test
SELECT field2 = @test

I found a more straight forward solution from @DK comment in this question, the solution is written by Alex and described here with source, To make customized window:

1. download the sample project here
2. edit the generic.xaml file to customize the layout.
3. enjoy :).

Many of the existing answers already touch the copy constructor, assignment operator and destructor. However, in post C++11, the introduction of move semantic may expand this beyond 3.

Recently Michael Claisse gave a talk that touches this topic: http://channel9.msdn.com/events/CPP/C-PP-Con-2014/The-Canonical-Class

Here is the code for the short version of if-then-else statement:

( [ $a -eq 1 ] || [ $b -eq 2 ] ) && echo "ok" || echo "nok"

Pay attention to the following:

1. || and && operands inside if condition (i.e. between round parentheses) are logical operands (or/and)

2. || and && operands outside if condition mean then/else

Practically the statement says:

if (a=1 or b=2) then "ok" else "nok"

Got this from Bing. Seems Microsoft has removed some features from the core framework and added it to a separate optional(?) framework component.

To quote from MSDN (http://msdn.microsoft.com/en-us/library/cc656912.aspx)

The .NET Framework 4 Client Profile does not include the following features. You must install the .NET Framework 4 to use these features in your application:

* ASP.NET
* Advanced Windows Communication Foundation (WCF) functionality
* .NET Framework Data Provider for Oracle
* MSBuild for compiling

Use JSON classes for parsing e.g

JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String  uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");

JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
....

It can, because a is a variable allocated temporarily for the lifetime of its scope (foo function). After you return from foo the memory is free and can be overwritten.

What you're doing is described as undefined behavior. The result cannot be predicted.

Using java.nio.Path it would be quite simple -

public static Path createFileWithDir(String directory, String filename) {
        File dir = new File(directory);
        if (!dir.exists()) dir.mkdirs();
        return Paths.get(directory + File.separatorChar + filename);
    }

This is a broad question and there are multiple ways you can achieve this. In my experience, I've seen a lot of single page applications having an entry point file such as index.js. This file would be responsible for 'bootstrapping' the application and will be your entry point for webpack.

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import Application from './components/Application';

const root = document.getElementById('someElementIdHere');

ReactDOM.render(
  <Application />,
  root,
);

Your <Application /> component would contain the next pieces of your app. You've stated you want different pages and that leads me to believe you're using some sort of routing. That could be included into this component along with any libraries that need to be invoked on application start. react-router, redux, redux-saga, react-devtools come to mind. This way, you'll only need to add a single entry point into your webpack configuration and everything will trickle down in a sense.

When you've setup a router, you'll have options to set a component to a specific matched route. If you had a URL of /about, you should create the route in whatever routing package you're using and create a component of About.js with whatever information you need.

I think the best way is to use currentTarget property instead of target property.

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred.

For example:

<a href="#"><span class="icon"></span> blah blah</a>

Javascript:

a.addEventListener('click', e => {
    e.currentTarget; // always returns "a" element
    e.target; // may return "a" or "span"
})

Oh, I just found that command on PostgreSQL forum:

SELECT * FROM pg_stat_activity;

#! /bin/bash

file="$@"
realpath "$file" 2>/dev/null || eval realpath $(echo $file | sed 's/ /\\ /g')

This makes up for the shortcomings of realpath, store it in a shell script fullpath. You can now call:

$ cd && touch a\ a && rm A 2>/dev/null 
$ fullpath "a a"
/home/user/a a
$ fullpath ~/a\ a
/home/user/a a
$ fullpath A
A: No such file or directory.

The reason you get a Null Pointer Exception is because there is no key likesZZZ in your second example. Try:

def mymap = [name:"Gromit", likes:"cheese", id:1234]
def x = mymap.find{ it.key == "likes" }.value
if(x)
    println "x value: ${x}"

I personally use Cygwin, which puts the entire smörgåsbord of Linux utilities at my fingertip --- there's md5sum and all the cryptographic digests supported by OpenSSL. Alternatively, you can also use a Windows distribution of OpenSSL (the "light" version is only a 1 MB installer).

Visual Studio (full version) is a "full-featured" and "convenient" development environment.

Visual Studio (free "Express" versions - only until 2017) are feature-centered and simplified versions of the full version. Feature-centered meaning that there are different versions (Visual Studio Web Developer, Visual Studio C#, etc.) depending on your goal.

Visual Studio (free Community edition - since 2015) is a simplified version of the full version and replaces the separated express editions used before 2015.

Visual Studio Code (VSCode) is a cross-platform (Linux, Mac OS, Windows) editor that can be extended with plugins to your needs.

For example, if you want to create an ASP.NET application using Visual Studio Code you need to perform several steps on your own to setup the project. There is a separate tutorial for each OS.

I had the same issue and the base environment was in C:\ProgramData\Anaconda3. This is the case, when Anaconda is installed for all users.

As a solution, I re-installed Anaconda just for me and now the base environment is in \AppData\Local\Continuum\anaconda3. This now can be updated via conda update without admin privileges.

Keep using private by default. If a member shouldn't be exposed beyond that type, it shouldn't be exposed beyond that type, even to within the same project. This keeps things safer and tidier - when you're using the object, it's clearer which methods you're meant to be able to use.

Having said that, I think it's reasonable to make naturally-private methods internal for test purposes sometimes. I prefer that to using reflection, which is refactoring-unfriendly.

One thing to consider might be a "ForTest" suffix:

internal void DoThisForTest(string name)
{
    DoThis(name);
}

private void DoThis(string name)
{
    // Real implementation
}

Then when you're using the class within the same project, it's obvious (now and in the future) that you shouldn't really be using this method - it's only there for test purposes. This is a bit hacky, and not something I do myself, but it's at least worth consideration.

<li class="nav-item">
    <a class="nav-link text-dark" asp-area="" asp-page="/UsersPage">Users</a>
</li>

Try this

Try something like:

$('div.toggle').hide();
$('ul.product-info li a').click(function(event) {
    event.preventDefault();
    $(this).next('div').slideToggle(200);
});

Here is the page about that in the jQuery documentation

I have had lots of issues with hidden and not visible inputs over the past decade sometimes things are way simpler than we think.

I have had a little wish with IE 5,6,7,8 and 9 for not supporting the opacity and thus the file input would cover the upload image however the following css code has resolved the issue.

-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: alpha(opacity=0);  

The following snipped is tested on chrome, IE 5,6,7,8,9,10 the only issue in IE 5 is that it does not support auto margin.

Run the snippet simply copy and paste the CSS and HTML modify the size as you like.

Past 10g the current answer no longer works for renaming views. The only method that still works is dropping and recreating the view. The best way I can think of to do this would be:

SELECT TEXT FROM ALL_VIEWS WHERE owner='some_schema' and VIEW_NAME='some_view';

Add this in front of the SQL returned

Create or replace view some_schema.new_view_name as ...

Drop the old view

Drop view some_schema.some_view;

use comma separated values in application.yml

ignoreFilenames: .DS_Store, .hg

java code for access

@Value("${ignoreFilenames}")    
String[] ignoreFilenames

It is working ;)

Assuming you're referring to MS-DOS batch files: as it is simply a text file with a special extension, a .bat file doesn't store an icon of its own.

You can, however, create a shortcut in the .lnk format that stores an icon.

I use following in my codes,

   for i in range(0, 10):
    try:
        #things I need to do
    except ValueError:
        print("Try #{} failed with ValueError: Sleeping for 2 secs before next try:".format(i))
        time.sleep(2)
        continue
    break

You can convert your primitive int array into an arraylist of Integers using below Java 8 code,

List<Integer> arrayElementsList = Arrays.stream(yourArray).boxed().collect(Collectors.toList());

And then use contains() method to check if the list contains a particular element,

boolean containsElement = arrayElementsList.contains(key);

We handle the "General Network Error" as a timeout exception too. It only occurs under rare circumstances e.g. when your update/insert/delete query will raise a long running trigger.

For me, none of suggestions worked giving me the errors of syntax, so I just gave a try using phpmyadmin(version 4.9.2), (10.4.10-MariaDB) and added id column with auto-increment primary key. Id column was nicely added from the first element.

Query output was:

ALTER TABLE table_name ADD id INT NOT NULL AUTO_INCREMENT FIRST, ADD PRIMARY KEY (id);

First of all, when you create ob1 then constructor is called and it starts execution. At that time t.start() also runs in separate thread. Remember when a new thread is created, it runs parallely to main thread. And thats why main start execution again with next statement.

And Join() statement is used to prevent the child thread from becoming orphan. Means if you did'nt call join() in your main class, then main thread will exit after its execution and child thread will be still there executing the statements. Join() will wait until all child thread complete its execution and then only main method will exit.

Go through this article, helps a lot.

You have already assigned a value to list.
So, you cannot use the list() when it’s a variable.
Restart the shell or IDE, by pressing Ctrl+F6 on your computer.

Since 2019 you can now use the new functionality called Github package registry.

Basically the process is:

• generate a new personal access token from the github settings
• add repository and token info in your settings.xml

• deploy using

  mvn deploy -Dregistry=https://maven.pkg.github.com/yourusername -Dtoken=yor_token  
  

Change hibernate.cfg.xml to:

<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>

Include log4j and below entries in "log4j.properties":

log4j.logger.org.hibernate=INFO, hb

If your git says you are commit ahead then just First,

git push origin

To make sure u have pushed all ur latest work in repo

Then,

git reset --hard origin/master

To reset and match up with the repo

You can use a $ sign like:

OUTPUT=$(expression)

<button type ="button" onclick="location.href='@Url.Action("viewname","Controllername")'"> Button name</button>

for e.g ,

<button type="button" onclick="location.href='@Url.Action("register","Home")'">Register</button>

when you manually open the IP address (via the RUN command or mapping a network drive), your PC will send your credentials over the pipe and the file server will receive authorization from the DC.

When ASP.Net tries, then it is going to try to use the IIS worker user (unless impersonation is turned on which will list a few other issues). Traditionally, the IIS worker user does not have authorization to work across servers (or even in other folders on the web server).

I know this post is about adding a single line break but I thought I would mention that you can create multiple line breaks with the backslash (\) character:

Hello
\
\
\
World!

This would result in 3 new lines after "Hello". To clarify, that would mean 2 empty lines between "Hello" and "World!". It would display like this:

World!

Personally I find this cleaner for a large number of line breaks compared to using <br>.

Note that backslashes are not recommended for compatibility reasons. So this may not be supported by your Markdown parser but it's handy when it is.

You can use a 1 pixel per 1 pixel Java applet embedded in the page and use that for compression.

It's not JavaScript and the clients will need a Java runtime but it will do what you need.

The original code for the Cocoa frameworks came from the NeXTSTEP libraries Foundation and AppKit (those names are still used by Apple's Cocoa frameworks), and the NextStep engineers chose to prefix their symbols with NS.

Because Objective-C is an extension of C and thus doesn't have namespaces like in C++, symbols must be prefixed with a unique prefix so that they don't collide. This is particularly important for symbols defined in a framework.

If you are writing an application, such that your code is only likely ever to use your symbols, you don't have to worry about this. But if you're writing a framework or library for others' use, you should also prefix your symbols with a unique prefix. CocoaDev has a page where many developers in the Cocoa community have listed their "chosen" prefixes. You may also find this SO discussion helpful.

Here are some vendors you might me looking for

::-webkit-input-placeholder {color: tomato}
::-moz-placeholder          {color: tomato;} /* Firefox 19+ */
:-moz-placeholder           {color: tomato;} /* Firefox 18- */
:-ms-input-placeholder      {color: tomato;}

You can also style different states, such as focus

:focus::-webkit-input-placeholder {color: transparent}
:focus::-moz-placeholder          {color: transparent}
:focus:-moz-placeholder           {color: transparent}
:focus:-ms-input-placeholder      {color: transparent}

You can also do certain transitions on it, like

::-VENDOR-input-placeholder       {text-indent: 0px;   transition: text-indent 0.3s ease;}
:focus::-VENDOR-input-placeholder  {text-indent: 500px; transition: text-indent 0.3s ease;}

Uninstall and then reinstall postgresql-client libpq5 libpq-dev

sudo apt remove postgresql-client libpq5 libpq-dev
sudo apt install postgresql-client libpq5 libpq-dev

Then install the pg gem again pointing at /usr/lib to find the pg library:

gem install pg  --   --with-pg-lib=/usr/lib

Output (what you should see after the previous command):

Building native extensions with: '--with-pg-lib=/usr/lib'
This could take a while...
Successfully installed pg-1.2.3
Parsing documentation for pg-1.2.3
Installing ri documentation for pg-1.2.3

Gem should install, then continue with normal bundle install or update:

bundle
bundle install
bundle update

head works too:

head -c 100 file  # returns the first 100 bytes in the file

..will extract the first 100 bytes and return them.

What's nice about using head for this is that the syntax for tail matches:

tail -c 100 file  # returns the last 100 bytes in the file

You can combine these to get ranges of bytes. For example, to get the second 100 bytes from a file, read the first 200 with head and use tail to get the last 100:

head -c 200 file | tail -c 100

Just yesterday I've added my git-analytics docker-compose file, which builds up several containers to start analyzing multiple git repositories against each other.

It is able to show you commit statistics over time about the author and also several diff statistics.

You can use the provided angular client and also kibana to visualize the statistics.

https://github.com/alexejsailer/git-analytics-docker

It will be improved over time.

For Eclipse Kepler, there is no Help > About Eclipse but I found this works:

Open your.gitconfig file to add the longpaths property. So it will look like the following:

[core]
symlinks = false
autocrlf = true
longpaths = true

TimeUnit.SECONDS.convert(start6, TimeUnit.MILLISECONDS);

My preference is to use as little code as possible...

You can do it using IN try this:

SELECT * 
FROM t1 WHERE (id,rev) IN 
( SELECT id, MAX(rev)
  FROM t1
  GROUP BY id
)

to my mind it is less complicated... easier to read and maintain.

If you want to update data you should use UPDATE command instead of INSERT

echo $$ # Gives the Parent Process ID 
ps -ef | grep $$ | awk '{print $8}' # Use the PID to see what the process is.

From How do you know what your current shell is?.

There is no place on your phone that you can read the System.out.println();

Instead, if you want to see the result of something either look at your logcat/console window or make a Toast or a Snackbar (if you're on a newer device) appear on the device's screen with the message :) That's what i do when i have to check for example where it goes in a switch case code! Have fun coding! :)

If you don't have another time interval bigger than days:

int days = (int) (milliseconds / (1000*60*60*24));

If you have weeks too:

int days = (int) ((milliseconds / (1000*60*60*24)) % 7);
int weeks = (int) (milliseconds / (1000*60*60*24*7));

It's probably best to avoid using months and years if possible, as they don't have a well-defined fixed length. Strictly speaking neither do days: daylight saving means that days can have a length that is not 24 hours.

Update April 2016 - for VS2013+

Microsoft started to address the issue in late 2015 by releasing VisualStudioUninstaller.

They abandoned the solution for a while; however work has begun again again as of April 2016.

There has finally been an official release for this uninstaller in April 2016 which is described as being "designed to cleanup/scorch all Preview/RC/RTM releases of Visual Studio 2013, Visual Studio 2015 and Visual Studio vNext".

Original Answer - for VS2010, VS2012

Note that the following two solutions still leave traces (such as registry files) and can't really be considered a 'clean' uninstall (see the final section of the answer for a completely clean solution).

Solution 1 - for: VS 2010

There's an uninstaller provided by Microsoft called the Visual Studio 2010 Uninstall Utility. It comes with three options:

1. Default (VS2010_Uninstall-RTM.ENU.exe)
2. Full (VS2010_Uninstall-RTM.ENU.exe /full)
3. Complete (VS2010_Uninstall-RTM.ENU.exe /full /netfx)

The above link explains the uninstaller in greater detail - I recommend reading the comments on the article before using it as some have noted problems (and workarounds) when service packs are installed. Afterwards, use something like CCleaner to remove the leftover registry files.

Here is the link to the download page of the VS2010 UU.

Solution 2 - for: VS 2010, VS 2012

Microsoft provide an uninstall /force feature that removes most remnants of either VS2010 or VS2012 from your computer.

MSDN: How to uninstall Visual Studio 2010/2012. From the link:

Warning: Running this command may remove some packages even if they are still in use like those listed in Optional shared packages.

1. Download the setup application you used to originally install Visual Studio 2012. If you installed from media, please insert that media.
2. Open a command prompt. Click Run on the Start menu (Start + R). Type cmd and press OK (Enter).
3. Type in the full path to the setup application and pass the following command line switches: /uninstall /force Example: D:\vs_ultimate.exe /uninstall /force
4. Click the Uninstall button and follow the prompts.

Afterwards, use something like CCleaner to remove the leftover registry files.

A completely clean uninstall?

Sadly, the only (current) way to achieve this is to follow dnLL's advice in their answer and perform a complete operating system reinstall. Then, in future, you could use Visual Studio inside a Virtual Machine instead and not have to worry about these issues again.

You need to convert your image to a numpy array this way:

import numpy
import PIL

img = PIL.Image.open("foo.jpg").convert("L")
imgarr = numpy.array(img) 

When using a terminal like PuTTY, usually mouse clicks and selections are not transmitted to the remote system. So, vi has no idea that you just selected some text. (There are exceptions to this, but in general mouse actions aren't transmitted.)

To delete multiple lines in vi, use something like 5dd to delete 5 lines.

If you're not using Vim, I would strongly recommend doing so. You can use visual selection, where you press V to start a visual block, move the cursor to the other end, and press d to delete (or any other editing command, such as y to copy).

from os import system, remove
from uuid import uuid4

def bash_(shell_command: str) -> tuple:
    """

    :param shell_command: your shell command
    :return: ( 1 | 0, stdout)
    """

    logfile: str = '/tmp/%s' % uuid4().hex
    err: int = system('%s &> %s' % (shell_command, logfile))
    out: str = open(logfile, 'r').read()
    remove(logfile)
    return err, out

# Example: 
print(bash_('cat /usr/bin/vi | wc -l'))
>>> (0, '3296\n')```

Thats where asp.net puts dynamically compiled assemblies.

You may find this thread useful. And here's a google code project exemplifying this (it P/Invokes into setupapi.dll).

You can use group by instead of distinct. Because when you use distinct, you'll get struggle to select all values from table. Unlike when you use group by, you can get distinct values and also all fields in table.

If you don't have the token at the time of the call is made, You will have to make two calls, one to get the token and the other to extract the token form the response, pay attention to

grep token | cut -d, -f1 | cut -d\" -f4

as it is the part which is dealing with extracting the token from the response.

echo "Getting token response and extracting token"    
def token = sh (returnStdout: true, script: """
    curl -S -i -k -X POST https://www.example.com/getToken -H \"Content-Type: application/json\" -H \"Accept: application/json\" -d @requestFile.json | grep token | cut -d, -f1 | cut -d\\" -f4
""").split()

After extracting the token you can use the token to make subsequent calls as follows.

echo "Token : ${token[-1]}"       
echo "Making calls using token..."       
curl -S -i -k  -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer ${token[-1]}" https://www.example.com/api/resources 

I like Consolas a lot. This top-10 list is a good resource for others. It includes examples and descriptions.

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

This (mysql_connect, mysql_...) extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used.

• Object Oriented:

  $mysqli = new mysqli("host", "user", "password");
  $mysqli->select_db("db");
  

• Procedural:

  $link = mysqli_connect("host","user","password") or die(mysqli_error($link)); 
  mysqli_select_db($link, "db");
