Entity interface

public interface Entity<I> extends Serializable {

/**
 * @return entity identity
 */
I getId();

/**
 * @return HashCode of entity identity
 */
int identityHashCode();

/**
 * @param other
 *            Other entity
 * @return true if identities of entities are equal
 */
boolean identityEquals(Entity<?> other);
}

Basic implementation for all Entities, simplifies Equals/Hashcode implementations:

public abstract class AbstractEntity<I> implements Entity<I> {

@Override
public final boolean identityEquals(Entity<?> other) {
    if (getId() == null) {
        return false;
    }
    return getId().equals(other.getId());
}

@Override
public final int identityHashCode() {
    return new HashCodeBuilder().append(this.getId()).toHashCode();
}

@Override
public final int hashCode() {
    return identityHashCode();
}

@Override
public final boolean equals(final Object o) {
    if (this == o) {
        return true;
    }
    if ((o == null) || (getClass() != o.getClass())) {
        return false;
    }

    return identityEquals((Entity<?>) o);
}

@Override
public String toString() {
    return getClass().getSimpleName() + ": " + identity();
    // OR 
    // return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}

Room Entity impl:

@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;

@Column(name = "number") 
private String number; //immutable

@Column(name = "capacity")
private Integer capacity;

@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable

Room() {
    // default constructor
}

public Room(Building building, String number) {
    // constructor with required field
    notNull(building, "Method called with null parameter (application)");
    notNull(number, "Method called with null parameter (name)");

    this.building = building;
    this.number = number;
}

public Integer getId(){
    return id;
}

public Building getBuilding() {
    return building;
}

public String getNumber() {
    return number;
}


public void setCapacity(Integer capacity) {
    this.capacity = capacity;
}

//no setters for number, building nor id
}

I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).

Slightly off-topic to your question, but it's probably worth mentioning anyway:

Commons Lang has got some excellent methods you can use in overriding equals and hashcode. Check out EqualsBuilder.reflectionEquals(...) and HashCodeBuilder.reflectionHashCode(...). Saved me plenty of headache in the past - although of course if you just want to do "equals" on ID it may not fit your circumstances.

I also agree that you should use the @Override annotation whenever you're overriding equals (or any other method).

if age is int you should use == if it is Integer object then you can use equals(). You also need to implement hashcode method if you override equals. Details of the contract is available in the javadoc of Object and also at various pages in web.

I don't think there is a "apache-common-like" tool to compare maps since the equality of 2 maps is very ambiguous and depends on the developer needs and the map implementation...

For exemple if you compare two hashmaps in java: - You may want to just compare key/values are the same - You may also want to compare if the keys are ordered the same way - You may also want to compare if the remaining capacity is the same ... You can compare a lot of things!

What such a tool would do when comparing 2 different map implementations such that: - One map allow null keys - The other throw runtime exception on map2.get(null)

You'd better to implement your own solution according to what you really need to do, and i think you already got some answers above :)

A simple solution to this issue that many people don't realize is to sort the JSON strings (per character). This is also usually faster than the other solutions mentioned here:

function areEqual(obj1, obj2) {
    var a = JSON.stringify(obj1), b = JSON.stringify(obj2);
    if (!a) a = '';
    if (!b) b = '';
    return (a.split('').sort().join('') == b.split('').sort().join(''));
}

Another useful thing about this method is you can filter comparisons by passing a "replacer" function to the JSON.stringify functions (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#Example_of_using_replacer_parameter). The following will only compare all objects keys that are named "derp":

function areEqual(obj1, obj2, filter) {
    var a = JSON.stringify(obj1, filter), b = JSON.stringify(obj2, filter);
    if (!a) a = '';
    if (!b) b = '';
    return (a.split('').sort().join('') == b.split('').sort().join(''));
}
var equal = areEqual(obj1, obj2, function(key, value) {
    return (key === 'derp') ? value : undefined;
});

"Not equals" can be expressed with the "not" operator ! and the standard .equals.

if (a.equals(b)) // a equals b
if (!a.equals(b)) // a not equal to b

If you use eclipse, you can generate equals() and hashCode() using:

Source -> Generate hashCode() and equals().

Using this function you can decide which fields you want to use for equality and hash code calculation, and Eclipse generates the corresponding methods.

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

The best way to compare 2 objects is by converting them into json strings and compare the strings, its the easiest solution when dealing with complicated nested objects, fields and/or objects that contain arrays.

sample:

import com.google.gson.Gson;


Object a = // ...;
Object b = //...;
String objectString1 = new Gson().toJson(a);
String objectString2 = new Gson().toJson(b); 

if(objectString1.equals(objectString2)){
    //do this
}

Instead of using array you can use the ArrayList directly and can use the contains method to check the value which u have passes with the ArrayList.

The former is fastest. Turns out that val is immutable, and so a new string object is created with String.ToLowerCase(), rather than just direct comparison with the string comparer. Creating a new string object can be costly if you're doing this many times a second.

.equals() doesn't perform an intelligent comparison for most classes unless the class overrides it. If it's not defined for a (user) class, it behaves the same as ==.

Reference: http://www.leepoint.net/notes-java/data/expressions/22compareobjects.html http://www.leepoint.net/data/expressions/22compareobjects.html

Assume you have class (A) that aggregates two other (B) (C), and you need to store instances of (A) inside hashtable. Default implementation only allows distinguishing of instances, but not by (B) and (C). So two instances of A could be equal, but default wouldn't allow you to compare them in correct way.

Apache commons StringUtils.isNotEmpty is the best way to go.

One more thing to watch out for is if the second value was another Integer object instead of a literal '0', the '==' operator compares the object pointers and will not auto-unbox.

ie:

Integer a = new Integer(0);   
Integer b = new Integer(0);   
int c = 0;

boolean isSame_EqOperator = (a==b); //false!
boolean isSame_EqMethod = (a.equals(b)); //true
boolean isSame_EqAutoUnbox = ((a==c) && (a.equals(c)); //also true, because of auto-unbox

//Note: for initializing a and b, the Integer constructor 
// is called explicitly to avoid integer object caching 
// for the purpose of the example.
// Calling it explicitly ensures each integer is created 
// as a separate object as intended.
// Edited in response to comment by @nolith

You can try this:

: ${depth?"Error Message"} ## when your depth variable is not even declared or is unset.

NOTE: Here it's just ? after depth.

or

: ${depth:?"Error Message"} ## when your depth variable is declared but is null like: "depth=". 

NOTE: Here it's :? after depth.

Here if the variable depth is found null it will print the error message and then exit.

There is practical difference between string.Equals and ==

bool result = false;

object obj = "String";    
string str2 = "String";
string str3 = typeof(string).Name;
string str4 = "String";
object obj2 = str3;

// Comparision between object obj and string str2 -- Com 1
result = string.Equals(obj, str2);// true
result = String.ReferenceEquals(obj, str2); // true
result = (obj == str2);// true

// Comparision between object obj and string str3 -- Com 2
result = string.Equals(obj, str3);// true
result = String.ReferenceEquals(obj, str3); // false
result = (obj == str3);// false

// Comparision between object obj and string str4 -- Com 3
result = string.Equals(obj, str4);// true
result = String.ReferenceEquals(obj, str4); // true
result = (obj == str4);// true

// Comparision between string str2 and string str3 -- Com 4
result = string.Equals(str2, str3);// true
result = String.ReferenceEquals(str2, str3); // false
result = (str2 == str3);// true

// Comparision between string str2 and string str4 -- Com 5
result = string.Equals(str2, str4);// true
result = String.ReferenceEquals(str2, str4); // true
result = (str2 == str4);// true

// Comparision between string str3 and string str4 -- Com 6
result = string.Equals(str3, str4);// true
result = String.ReferenceEquals(str3, str4); // false
result = (str3 == str4);// true

// Comparision between object obj and object obj2 -- Com 7
result = String.Equals(obj, obj2);// true
result = String.ReferenceEquals(obj, obj2); // false
result = (obj == obj2);// false

Adding Watch

obj     "String" {1#}   object {string}
str2    "String" {1#}   string
str3    "String" {5#}   string
str4    "String" {1#}   string
obj2    "String" {5#}   object {string}

Now look at {1#} and {5#}

obj, str2, str4 and obj2 references are same.

obj and obj2 are object type and others are string type

Conclusion:

1. com1: result = (obj == str2);// true
   • compares object and string so performs a reference equality check
   • obj and str2 point to the same reference so the result is true
2. com2: result = (obj == str3);// false
   • compares object and string so performs a reference equality check
   • obj and str3 point to the different references so the result is false
3. com3: result = (obj == str4);// true
   • compares object and string so performs a reference equality check
   • obj and str4 point to the same reference so the result is true
4. com4: result = (str2 == str3);// true
   • compares string and string so performs a string value check
   • str2 and str3 are both "String" so the result is true
5. com5: result = (str2 == str4);// true
   • compares string and string so performs a string value check
   • str2 and str4 are both "String" so the result is true
6. com6: result = (str3 == str4);// true
   • compares string and string so performs a string value check
   • str3 and str4 are both "String" so the result is true
7. com7: result = (obj == obj2);// false  - compares object and object so performs a reference equality check      - obj and obj2 point to the different references so the result is false

The reason to use getClass is to ensure the symmetric property of the equals contract. From equals' JavaDocs:

It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.

By using instanceof, it's possible to not be symmetric. Consider the example: Dog extends Animal. Animal's equals does an instanceof check of Animal. Dog's equals does an instanceof check of Dog. Give Animal a and Dog d (with other fields the same):

a.equals(d) --> true
d.equals(a) --> false

This violates the symmetric property.

To strictly follow equal's contract, symmetry must be ensured, and thus the class needs to be the same.

"" is an actual string, albeit an empty one.

null, however, means that the String variable points to nothing.

a==b returns false because "" and null do not occupy the same space in memory--in other words, their variables don't point to the same objects.

a.equals(b) returns false because "" does not equal null, obviously.

The difference is though that since "" is an actual string, you can still invoke methods or functions on it like

a.length()

a.substring(0, 1)

and so on.

If the String equals null, like b, Java would throw a NullPointerException if you tried invoking, say:

b.length()

If the difference you are wondering about is == versus equals, it's this:

== compares references, like if I went

String a = new String("");
String b = new String("");
System.out.println(a==b);

That would output false because I allocated two different objects, and a and b point to different objects.

However, a.equals(b) in this case would return true, because equals for Strings will return true if and only if the argument String is not null and represents the same sequence of characters.

Be warned, though, that Java does have a special case for Strings.

String a = "abc";
String b = "abc";
System.out.println(a==b);

You would think that the output would be false, since it should allocate two different Strings. Actually, Java will intern literal Strings (ones that are initialized like a and b in our example). So be careful, because that can give some false positives on how == works.

==

The == operator can be used to compare two variables of any kind, and it simply compares the bits.

int a = 3;
byte b = 3;
if (a == b) { // true }

Note : there are more zeroes on the left side of the int but we don't care about that here.

int a (00000011) == byte b (00000011)

Remember == operator cares only about the pattern of the bits in the variable.

Use == If two references (primitives) refers to the same object on the heap.

Rules are same whether the variable is a reference or primitive.

Foo a = new Foo();
Foo b = new Foo();
Foo c = a;

if (a == b) { // false }
if (a == c) { // true }
if (b == c) { // false }

a == c is true a == b is false

the bit pattern are the same for a and c, so they are equal using ==.

Equal():

Use the equals() method to see if two different objects are equal.

Such as two different String objects that both represent the characters in "Jane"

I believe that the correct answer would be to make the two numbers (BigDecimals), have the same scale, then we can decide about their equality. For example, are these two numbers equal?

1.00001 and 1.00002

Well, it depends on the scale. On the scale 5 (5 decimal points), no they are not the same. but on smaller decimal precisions (scale 4 and lower) they are considered equal. So I suggest make the scale of the two numbers equal and then compare them.

Here is a simple interpretation about your problem:

== (equal to) used to evaluate arithmetic expression

where as

equals() method used to compare string

Therefore, it its better to use == for numeric operations & equals() method for String related operations. So, for comparison of objects the equals() method would be right choice.

As written, this question is ambigous. The statement:

... they both have the same elements, regardless of their position within the list. Each MyType object may appear multiple times on a list.

does not indicate whether you want to ensure that the two lists have the same set of objects or the same distinct set.

If you want to ensure to collections have exactly the same set of members regardless of order, you can use:

// lists should have same count of items, and set difference must be empty
var areEquivalent = (list1.Count == list2.Count) && !list1.Except(list2).Any();

If you want to ensure two collections have the same distinct set of members (where duplicates in either are ignored), you can use:

// check that [(A-B) Union (B-A)] is empty
var areEquivalent = !list1.Except(list2).Union( list2.Except(list1) ).Any();

Using the set operations (Intersect, Union, Except) is more efficient than using methods like Contains. In my opinion, it also better expresses the expectations of your query.

EDIT: Now that you've clarified your question, I can say that you want to use the first form - since duplicates matter. Here's a simple example to demonstrate that you get the result you want:

var a = new[] {1, 2, 3, 4, 4, 3, 1, 1, 2};
var b = new[] { 4, 3, 2, 3, 1, 1, 1, 4, 2 };

// result below should be true, since the two sets are equivalent...
var areEquivalent = (a.Count() == b.Count()) && !a.Except(b).Any(); 

You should read up on how to ensure that you've implemented equals and hashCode properly. This is a good starting point: What issues should be considered when overriding equals and hashCode in Java?

this is the current Object instance. Whenever you have a non-static method, it can only be called on an instance of your object.

// Select and loop the container element of the elements you want to equalise
        $('.equal').each(function(){  

          // Cache the highest
          var highestBox = 0;

          // Select and loop the elements you want to equalise
          $('.col-lg-4', this).each(function(){

            // If this box is higher than the cached highest then store it
            if($(this).height() > highestBox) {
              highestBox = $(this).height(); 
            }

          });  

          // Set the height of all those children to whichever was highest 
          $('.col-lg-4',this).height(highestBox);

        }); 

    });

Think of ! (negation operator) as "not", || (boolean-or operator) as "or" and && (boolean-and operator) as "and". See Operators and Operator Precedence.

Thus:

if(!(a || b)) {
  // means neither a nor b
}

However, using De Morgan's Law, it could be written as:

if(!a && !b) {
  // is not a and is not b
}

a and b above can be any expression (such as test == 'B' or whatever it needs to be).

Once again, if test == 'A' and test == 'B', are the expressions, note the expansion of the 1st form:

// if(!(a || b)) 
if(!((test == 'A') || (test == 'B')))
// or more simply, removing the inner parenthesis as
// || and && have a lower precedence than comparison and negation operators
if(!(test == 'A' || test == 'B'))
// and using DeMorgan's, we can turn this into
// this is the same as substituting into if(!a && !b)
if(!(test == 'A') && !(test == 'B'))
// and this can be simplified as !(x == y) is the same as (x != y)
if(test != 'A' && test != 'B')

For equals, look into Secrets of Equals by Angelika Langer. I love it very much. She's also a great FAQ about Generics in Java. View her other articles here (scroll down to "Core Java"), where she also goes on with Part-2 and "mixed type comparison". Have fun reading them!

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

You better use the Java HashMap object for that purpose http://download.oracle.com/javase/1,5.0/docs/api/java/util/HashMap.html

I believe equals and equalsIgnoreCase methods of String return true and false which is useful if you wanted to compare the values of the string object, But in case of implementing compareTo and compareToIgnoreCase methods returns positive, negative and zero value which will be useful in case of sorting.

This is a copy/paste of another answer of mine for question SQL 'like' vs '=' performance:

A personal example using mysql 5.5: I had an inner join between 2 tables, one of 3 million rows and one of 10 thousand rows.

When using a like on an index as below(no wildcards), it took about 30 seconds:

where login like '12345678'

using 'explain' I get:

When using an '=' on the same query, it took about 0.1 seconds:

where login ='12345678'

Using 'explain' I get:

As you can see, the like completely cancelled the index seek, so query took 300 times more time.

CSS properties should be set by cssText property or setAttribute method.

// Set multiple styles in a single statement
elt.style.cssText = "color: blue; border: 1px solid black"; 
// Or
elt.setAttribute("style", "color:red; border: 1px solid blue;");

Styles should not be set by assigning a string directly to the style property (as in elt.style = "color: blue;"), since it is considered read-only, as the style attribute returns a CSSStyleDeclaration object which is also read-only.

The onclick property is all lower-case, and accepts a function, not a string.

document.getElementById("test").onclick = foo2;

Although this is linked to Android documentation (Wayback Machine) and My own code on Github, it will work for Java in general. My answer is an extension of dmeister's Answer with just code that is much easier to read and understand.

@Override 
public int hashCode() {

    // Start with a non-zero constant. Prime is preferred
    int result = 17;

    // Include a hash for each field.

    // Primatives

    result = 31 * result + (booleanField ? 1 : 0);                   // 1 bit   » 32-bit

    result = 31 * result + byteField;                                // 8 bits  » 32-bit 
    result = 31 * result + charField;                                // 16 bits » 32-bit
    result = 31 * result + shortField;                               // 16 bits » 32-bit
    result = 31 * result + intField;                                 // 32 bits » 32-bit

    result = 31 * result + (int)(longField ^ (longField >>> 32));    // 64 bits » 32-bit

    result = 31 * result + Float.floatToIntBits(floatField);         // 32 bits » 32-bit

    long doubleFieldBits = Double.doubleToLongBits(doubleField);     // 64 bits (double) » 64-bit (long) » 32-bit (int)
    result = 31 * result + (int)(doubleFieldBits ^ (doubleFieldBits >>> 32));

    // Objects

    result = 31 * result + Arrays.hashCode(arrayField);              // var bits » 32-bit

    result = 31 * result + referenceField.hashCode();                // var bits » 32-bit (non-nullable)   
    result = 31 * result +                                           // var bits » 32-bit (nullable)   
        (nullableReferenceField == null
            ? 0
            : nullableReferenceField.hashCode());

    return result;

}

EDIT

Typically, when you override hashcode(...), you also want to override equals(...). So for those that will or has already implemented equals, here is a good reference from my Github...

@Override
public boolean equals(Object o) {

    // Optimization (not required).
    if (this == o) {
        return true;
    }

    // Return false if the other object has the wrong type, interface, or is null.
    if (!(o instanceof MyType)) {
        return false;
    }

    MyType lhs = (MyType) o; // lhs means "left hand side"

            // Primitive fields
    return     booleanField == lhs.booleanField
            && byteField    == lhs.byteField
            && charField    == lhs.charField
            && shortField   == lhs.shortField
            && intField     == lhs.intField
            && longField    == lhs.longField
            && floatField   == lhs.floatField
            && doubleField  == lhs.doubleField

            // Arrays

            && Arrays.equals(arrayField, lhs.arrayField)

            // Objects

            && referenceField.equals(lhs.referenceField)
            && (nullableReferenceField == null
                        ? lhs.nullableReferenceField == null
                        : nullableReferenceField.equals(lhs.nullableReferenceField));
}

I looked into this a bit more and the actual problem seems to be with assigning initial to page width under the print media rule. It seems like in Chrome width: initial on the .page element results in scaling of the page content if no specific length value is defined for width on any of the parent elements (width: initial in this case resolves to width: auto ... but actually any value smaller than the size defined under the @page rule causes the same issue).

So not only the content is now too long for the page (by about 2cm), but also the page padding will be slightly more than the initial 2cm and so on (it seems to render the contents under width: auto to the width of ~196mm and then scale the whole content up to the width of 210mm ~ but strangely exactly the same scaling factor is applied to contents with any width smaller than 210mm).

To fix this problem you can simply in the print media rule assign the A4 paper width and hight to html, body or directly to .page and in this case avoid the initial keyword.

DEMO

@page {
  size: A4;
  margin: 0;
}
@media print {
  html, body {
    width: 210mm;
    height: 297mm;
  }
  /* ... the rest of the rules ... */
}

^{This seems to keep everything else the way it is in your original CSS and fix the problem in Chrome (tested in different versions of Chrome under Windows, OS X and Ubuntu).}

Also try dojo.number which has built-in localization support. It is a much closer analog to Java's NumberFormat/DecimalFormat

Array is a JavaScript native object, why don't you just try to use the API of it? Knowing API on its own will save you time when you will switch to pure JavaScript or another framework.

There are number of different possibilities, so, use the one which mostly targets your needs.

Creating array with values:

var array = ["value1", "value2", "value3"];

Adding values to the end

var array = [];
array.push("value1");
array.push("value2");
array.push("value3");

Adding values to the begin:

var array = [];
array.unshift("value1");
array.unshift("value2");
array.unshift("value3");

Adding values at some index:

var array = [];
array[index] = "value1";

or by using splice

array.splice(index, 0, "value1", "value2", "value3");

Choose one you need.

list() is inherently slower than [], because

1. there is symbol lookup (no way for python to know in advance if you did not just redefine list to be something else!),

2. there is function invocation,

3. then it has to check if there was iterable argument passed (so it can create list with elements from it) ps. none in our case but there is "if" check

In most cases the speed difference won't make any practical difference though.

In Excel for Mac at least, you can do this by saving as "CSV for MS DOS" which adds double quotes for any field which needs them.

In Ubuntu 12.x, I added the following lines in $HOME/.wgetrc

http_proxy = http://uname:[email protected]:8080

use_proxy = on

Calling SubString() allocates a new string. For optimal performance, you should avoid that extra allocation. Starting with C# 7.2 you can take advantage of the Span pattern.

When targeting .NET Framework, include the System.Memory NuGet package. For .NET Core projects this works out of the box.

static void Main(string[] args)
{
    var str = "hello world!";
    var span = str.AsSpan(10); // No allocation!

    // Outputs: d!
    foreach (var c in span)
    {
        Console.Write(c);
    }

    Console.WriteLine();
}

I solved this issue by using the browser from within Visual Studio, View->Other Windows->Web Browser; Ctrl+Alt+R (or * Ctrl+W, W* in VS versions before VS2010) to navigate to the TFS page and log out of the wrong account and log back in.

For me, the issue was caused by using another live-id to unlock a windows phone for development. Somehow the credentials got cached, it seems.

To view the content in alert use:

alert( $(response).find("#result").html() );

boost::lexical_cast works pretty well.

#include <boost/lexical_cast.hpp>
int main(int argc, char** argv) {
    std::string foo = boost::lexical_cast<std::string>(argc);
}

$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

I think basic solutions to the question should be as below:

Supplier supplier=HashSet::new; 
HashSet has=ls.stream().collect(Collectors.toCollection(supplier));

List lst = (List) ls.stream().filter(e->Collections.frequency(ls,e)>1).distinct().collect(Collectors.toList());

well, it is not recommended to perform a filter operation, but for better understanding, i have used it, moreover, there should be some custom filtration in future versions.

After reading the Wikipedia page and other pages on real-time computing. I made the following inferences:

1> For a Hard real-time system, if the system fails to meet the deadline even once the system is considered to have Failed.

2> For a Firm real-time system, even if the system fails to meet the deadline, possibly more than once (i.e. for multiple requests), the system is not considered to have failed. Also, the responses for the requests (replies to a query, result of a task, etc.) are worthless once the deadline for that particular request has passed (The usefulness of a result is zero after its deadline). A hypothetical example can be a storm forecast system (if a storm is predicted before arrival, then the system has done its job, prediction after the event has already happened or when it is happening is of no value).

3> For a Soft real-time system, even if the system fails to meet the deadline, possibly more than once (i.e. for multiple requests), the system is not considered to have failed. But, in this case the results of the requests are not worthless value for a result after its deadline, is not zero, rather it degrades as time passes after the deadline. Eg.: Streaming audio-video.

Here is a link to a resource that was very helpful.

I simply write it this way

in the AspectType file:

class AspectType {
  //blah blah
}
module.exports = AspectType;

and import it like this:

const AspectType = require('./AspectType');
var aspectType = new AspectType;

There's good amount of detail on logging for shell scripts via global varaibles of shell. We can emulate the similar kind of logging in shell script: http://www.cubicrace.com/2016/03/efficient-logging-mechnism-in-shell.html The post has details on introdducing log levels like INFO , DEBUG, ERROR. Tracing details like script entry, script exit, function entry, function exit.

Sample Log:

You can LEFT JOIN the two tables. If there is no corresponding row in the second table, the values will be NULL.

SELECT id FROM partmaster LEFT JOIN product_details ON (...) WHERE product_details.part_num IS NULL

This is the solution I ended up using. I wanted an inline solution, and this so far seems to work great:

<textarea onkeyup="$(this).css('height', 'auto').css('height', this.scrollHeight + this.offsetHeight - this.clientHeight);"></textarea>

In answer to your general question of

So I am curious: What did I do to disorientate migrations? And what can I do to get it working with just one initial migration?

I've just had the same error message as you after I merged several branches and the migrations got confused about the current state of the database. Worst of all, this was only happening on the client's server, not on our development systems.

In trying to work out what was happening there, I came across this superb Microsoft guide:

Microsoft's guide to Code First Migrations in Team Environments

Whilst that guide was written to explain migrations in teams, it also gives the best explanation I've found of how the migrations work internally, which may well lead to an explanation for the behaviour your seeing. It's very worth putting an hour aside to read all of that for anyone who works with EF6 or below.

For anyone brought to this question by that error message after merging migrations, the trick of generating a blank migration with the current state of the database solved things for me, but do be very sure to have read the whole guide to know if that solution is appropriate in your case.

When it comes to inserting a picture, r2evans's suggestion of ![Caption for the picture.](/path/to/image.png) can be problematic if PDF output is required.

The knitr function include_graphics knitr::include_graphics('/path/to/image.png') is a more portable alternative that will generate, on your behalf, the markdown that is most appropriate to the output format that you are generating.

This should be rather a SuperUser question.

Right I have the exact same error inside MacOSX SourceTree, however, inside a iTerm2 terminal, things work just dandy.

However, the problem seemed to be that I've got two ssh-agents running ;(

The first being /usr/bin/ssh-agent (aka MacOSX's) and then also the HomeBrew installed /usr/local/bin/ssh-agent running.

Firing up a terminal from SourceTree, allowed me to see the differences in SSH_AUTH_SOCK, using lsof I found the two different ssh-agents and then I was able to load the keys (using ssh-add) into the system's default ssh-agent (ie. /usr/bin/ssh-agent), SourceTree was working again.

I formerly voted to close this question as off-topic but actually I changed my mind as this is quite nice visual effect which, unfortunately, is not yet part of support library. It will most likely show up in future update, but there's no time frame announced.

Luckily there are few custom implementations already available:

• https://github.com/traex/RippleEffect
• https://github.com/balysv/material-ripple
• https://github.com/siriscac/RippleView
• https://github.com/ozodrukh/RippleDrawable

including Materlial themed widget sets compatible with older versions of Android:

• https://github.com/keithellis/MaterialWidget

so you can try one of these or google for other "material widgets" or so...

The setDate() method sets the date and updates the associated control. Here is how:

$("#datepicker1").datepicker({
    dateFormat: "yy-mm-dd"
}).datepicker("setDate", "0");

Demo

As mentioned in documentation, setDate() happily accepts the JavaScript Date object, number or a string:

The new date may be a Date object or a string in the current date format (e.g. '01/26/2009'), a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null to clear the selected date.

In case you are wondering, setting defaultDate property in the constructor does not update the associated control.

Python datetime object has a method attribute, which prints in readable format.

>>> a = datetime.now()
>>> a.ctime()
'Mon May 21 18:35:18 2018'
>>> 

onCreate(Bundle savedInstanceState) gets called and savedInstanceState will be non-null if your Activity and it was terminated in a scenario(visual view) described above. Your app can then grab (catch) the data from savedInstanceState and regenerate your Activity

For the newbies like me among us: after a little research I figured out what the code jalf posted did.

A functor is a class or struct object which can be "called" like a function. This is made possible by overloading the () operator. The () operator (not sure what its called) can take any number of arguments. Other operators only take two i.e. the + operator can only take two values (one on each side of the operator) and return whatever value you have overloaded it for. You can fit any number of arguments inside a () operator which is what gives it its flexibility.

To create a functor first you create your class. Then you create a constructor to the class with a parameter of your choice of type and name. This is followed in the same statement by an initializer list (which uses a single colon operator, something I was also new to) which constructs the class member objects with the previously declared parameter to the constructor. Then the () operator is overloaded. Finally you declare the private objects of the class or struct you have created.

My code (I found jalf's variable names confusing)

class myFunctor
{ 
    public:
        /* myFunctor is the constructor. parameterVar is the parameter passed to
           the constructor. : is the initializer list operator. myObject is the
           private member object of the myFunctor class. parameterVar is passed
           to the () operator which takes it and adds it to myObject in the
           overloaded () operator function. */
        myFunctor (int parameterVar) : myObject( parameterVar ) {}

        /* the "operator" word is a keyword which indicates this function is an 
           overloaded operator function. The () following this just tells the
           compiler that () is the operator being overloaded. Following that is
           the parameter for the overloaded operator. This parameter is actually
           the argument "parameterVar" passed by the constructor we just wrote.
           The last part of this statement is the overloaded operators body
           which adds the parameter passed to the member object. */
        int operator() (int myArgument) { return myObject + myArgument; }

    private: 
        int myObject; //Our private member object.
}; 

If any of this is inaccurate or just plain wrong feel free to correct me!

Kotlin Solution

view.isVisible = true
view.isInvisible = true
view.isGone = true

// For these to work, you need to use androidx and import:
import androidx.core.view.isVisible // or isInvisible/isGone

Kotlin Extension Solution

If you'd like them to be more consistent length, work for nullable views, and lower the chance of writing the wrong boolean, try using these custom extensions:

// Example
view.hide()

fun View?.show() {
    if (this == null) return
    if (!isVisible) isVisible = true
}

fun View?.hide() {
    if (this == null) return
    if (!isInvisible) isInvisible = true
}

fun View?.gone() {
    if (this == null) return
    if (!isGone) isGone = true
}

To make conditional visibility simple, also add these:

fun View?.show(visible: Boolean) {
    if (visible) show() else gone()
}

fun View?.hide(hide: Boolean) {
    if (hide) hide() else show()
}

fun View?.gone(gone: Boolean = true) {
    if (gone) gone() else show()
}

Here is how:

<a href="#go_middle">Go Middle</a>

<div id="go_middle">Hello There</div>

Here are a few simple examples to see the difference in action:

See the list of numbers here:

nums = [1, 9, -3, 4, 8, 5, 7, 14]

When calling sorted on this list, sorted will make a copy of the list. (Meaning your original list will remain unchanged.)

Let's see.

sorted(nums)

returns

[-3, 1, 4, 5, 7, 8, 9, 14]

Looking at the nums again

nums

We see the original list (unaltered and NOT sorted.). sorted did not change the original list

[1, 2, -3, 4, 8, 5, 7, 14]

Taking the same nums list and applying the sort function on it, will change the actual list.

Let's see.

Starting with our nums list to make sure, the content is still the same.

nums

[-3, 1, 4, 5, 7, 8, 9, 14]

nums.sort()

Now the original nums list is changed and looking at nums we see our original list has changed and is now sorted.

nums
[-3, 1, 2, 4, 5, 7, 8, 14]

parseInt is misfeatured like scanf:

parseInt("12 monkeys", 10) is a number with value '12'
+"12 monkeys"              is a number with value 'NaN'
Number("12 monkeys")       is a number with value 'NaN'

Inspired by Steve, and as the updates for Java 11. Here's how we did the BigDecimal reformatting to avoid scientific notation.

public class PriceSerializer extends JsonSerializer<BigDecimal> {
    @Override
    public void serialize(BigDecimal value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
        // Using writNumber and removing toString make sure the output is number but not String.
        jgen.writeNumber(value.setScale(2, RoundingMode.HALF_UP));
    }
}

The KILL SESSION command doesn't actually kill the session. It merely asks the session to kill itself. In some situations, like waiting for a reply from a remote database or rolling back transactions, the session will not kill itself immediately and will wait for the current operation to complete. In these cases the session will have a status of "marked for kill". It will then be killed as soon as possible.

Check the status to confirm:

SELECT sid, serial#, status, username FROM v$session;

You could also use IMMEDIATE clause:

ALTER SYSTEM KILL SESSION 'sid,serial#' IMMEDIATE;

The IMMEDIATE clause does not affect the work performed by the command, but it returns control back to the current session immediately, rather than waiting for confirmation of the kill. Have a look at Killing Oracle Sessions.

Update If you want to kill all the sessions, you could just prepare a small script.

SELECT 'ALTER SYSTEM KILL SESSION '''||sid||','||serial#||''' IMMEDIATE;' FROM v$session;

Spool the above to a .sql file and execute it, or, copy paste the output and run it.

@fooMonster article worked for me

# git ls-tree HEAD
100644 blob 55c0287d4ef21f15b97eb1f107451b88b479bffe    script.sh

As you can see the file has 644 permission (ignoring the 100). We would like to change it to 755:

# git update-index --chmod=+x script.sh

commit the changes

# git commit -m "Changing file permissions"
[master 77b171e] Changing file permissions
0 files changed, 0 insertions(+), 0 deletions(-)
mode change 100644 => 100755 script.sh

as.character() would be the general way rather than use paste() for its side effect

> v <- 20081101
> date <- as.Date(as.character(v), format = "%Y%m%d")
> date
[1] "2008-11-01"

(I presume this is a simple example and something like this:

v <- "20081101"

isn't possible?)

This is what I do when I need to add months or years and don't want to import more libraries. Just create a datetime.date() object, call add_month(date) to add a month and add_year(date) to add a year.

            if (year % 400) == 0:
                return True
            else:
                return False
        else:
            return True
    else:
        return False

    delta = datetime.timedelta(days=current_month_days)
    if date.day > next_month_days:
        delta = delta - datetime.timedelta(days=(date.day - next_month_days) - 1)

    return date + delta

With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:

print *(myVector._M_impl._M_start)@myVector.size()

To print only the first N elements, do:

print *(myVector._M_impl._M_start)@N

Explanation

This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:

myVector._M_impl._M_start 

And the GDB command to print N elements of an array starting at pointer P is:

print P@N

Or, in a short form (for a standard .gdbinit):

p P@N

is so easy You can use [phpy - library for php][1] php file

<?php
  require_once "vendor/autoload.php";

  use app\core\App;

  $app = new App();
  $python = $app->python;
  $output = $python->set(your python path)->send(data..)->gen();
  var_dump($ouput);

python file:

import include.library.phpy as phpy
print(phpy.get_data(number of data , first = 1 , two =2 ...))

you can see also example in github page [1]: https://github.com/Raeen123/phpy

Personally,I prefer to use preg_match() function:

if(preg_match("/\.(gif|png|jpg)$/", $filename))

or in_array()

$exts = array('gif', 'png', 'jpg'); 
if(in_array(end(explode('.', $filename)), $exts)

With in_array() can be useful if you have a lot of extensions to validate and perfomance question. Another way to validade file images: you can use @imagecreatefrom*(), if the function fails, this mean the image is not valid.

For example:

function testimage($path)
{
   if(!preg_match("/\.(png|jpg|gif)$/",$path,$ext)) return 0;
   $ret = null;
   switch($ext)
   {
       case 'png': $ret = @imagecreatefrompng($path); break;
       case 'jpeg': $ret = @imagecreatefromjpeg($path); break;
       // ...
       default: $ret = 0;
   }

   return $ret;
}

then:

$valid = testimage('foo.png');

Assuming that foo.png is a PHP-script file with .png extension, the above function fails. It can avoid attacks like shell update and LFI.

The best place to find answers to general (and somewhat easy questions) such as this is to read up on PHP docs. Specifically in your case you can read more on objects. You can store stdObject and instantiated objects within an array. In fact, there is a process known as 'hydration' which populates the member variables of an object with values from a database row, then the object is stored in an array (possibly with other objects) and returned to the calling code for access.

-- Edit --

class Car
{
    public $color;
    public $type;
}

$myCar = new Car();
$myCar->color = 'red';
$myCar->type = 'sedan';

$yourCar = new Car();
$yourCar->color = 'blue';
$yourCar->type = 'suv';

$cars = array($myCar, $yourCar);

foreach ($cars as $car) {
    echo 'This car is a ' . $car->color . ' ' . $car->type . "\n";
}

You can try to force the soft keyboard to appear, it works for me:

...
dialog.show();
input.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

CSS isn't going to be able to call other elements like that, you'll need to use JavaScript to reach beyond a child or sibling selector.

You could try something like this:

<a>Some Link
<div><img src="/you/image" /></div>
</a>

then...

a>div { display: none; }
a:hover>div { display: block; }

It's easy. If you have two or more running container, complete next steps:

docker network create myNetwork
docker network connect myNetwork web1
docker network connect myNetwork web2

Now you connect from web1 to web2 container or the other way round.

Use the internal network IP addresses which you can find by running:

docker network inspect myNetwork

Note that only internal IP addresses and ports are accessible to the containers connected by the network bridge.

So for example assuming that web1 container was started with: docker run -p 80:8888 web1 (meaning that its server is running on port 8888 internally), and inspecting myNetwork shows that web1's IP is 172.0.0.2, you can connect from web2 to web1 using curl 172.0.0.2:8888).

The easiest way that I found for adding a column to a DataFrame was to use the "add" function. Here's a snippet of code, also with the output to a CSV file. Note that including the "columns" argument allows you to set the name of the column (which happens to be the same as the name of the np.array that I used as the source of the data).

#  now to create a PANDAS data frame
df = pd.DataFrame(data = FF_maxRSSBasal, columns=['FF_maxRSSBasal'])
# from here on, we use the trick of creating a new dataframe and then "add"ing it
df2 = pd.DataFrame(data = FF_maxRSSPrism, columns=['FF_maxRSSPrism'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = FF_maxRSSPyramidal, columns=['FF_maxRSSPyramidal'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_strainE22, columns=['deltaFF_strainE22'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = scaled, columns=['scaled'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_orientation, columns=['deltaFF_orientation'])
df = df.add( df2, fill_value=0 )
#print(df)
df.to_csv('FF_data_frame.csv')

all you need to know is in Jackson Documentation https://www.baeldung.com/jackson-serialize-dates

Ad.9 quick solved the problem for me.

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

using List Comprehension:

>>> L = [1]*5
>>> [x+1 for x in L]
[2, 2, 2, 2, 2]
>>> 

which roughly translates to using a for loop:

>>> newL = []
>>> for x in L:
...     newL+=[x+1]
... 
>>> newL
[2, 2, 2, 2, 2]

or using map:

>>> map(lambda x:x+1, L)
[2, 2, 2, 2, 2]
>>> 

Here is a code that works for me, which is a part from the website above combined with my early trials: http://www.codeproject.com/KB/system/DriveDetector.aspx

This basically makes your form listen to windows messages, filters for usb drives and (cd-dvds), grabs the lparam structure of the message and extracts the drive letter.

Do not forget to add this:

using System.Runtime.InteropServices;

and the following constants:

    const int WM_DEVICECHANGE = 0x0219; //see msdn site
    const int DBT_DEVICEARRIVAL = 0x8000;
    const int DBT_DEVICEREMOVALCOMPLETE = 0x8004;
    const int DBT_DEVTYPVOLUME = 0x00000002;  

Does playsinline attribute help?

Here's what I have:

<video autoplay loop muted playsinline class="video-background ">
  <source src="videos/intro-video3.mp4" type="video/mp4">

See the comment on playsinline here: https://webkit.org/blog/6784/new-video-policies-for-ios/

You can also look at the event.metaKey attribute on the event if you are working with keydown events. Worked wonderfully for me! You can try it here.

This one is very interesting,

If the number of UUID being generated follows Moore's law, the impression of never running out of GUID in the foreseeable future is false.

With 2 ^ 128 UUIDs, it will only take 18 months * Log2(2^128) ~= 192 years, before we run out of all UUIDs.

And I believe (with no statistical proof what-so-ever) in the past few years since mass adoption of UUID, the speed we are generating UUID is increasing way faster than Moore's law dictates. In other words, we probably have less than 192 years until we have to deal with UUID crisis, that's a lot sooner than end of universe.

But since we definitely won't be running them out by the end of 2012, we'll leave it to other species to worry about the problem.

If you override a parent method in its child, child objects will always use the overridden version. But; you can use the keyword super to call the parent method, inside the body of the child method.

public class PolyTest{
    public static void main(String args[]){
        new Child().foo();
    }

}
class Parent{
    public void foo(){
        System.out.println("I'm the parent.");
    }
}

class Child extends Parent{
    @Override
    public void foo(){
        //super.foo();
        System.out.println("I'm the child.");
    }
}

This would print:

I'm the child.

Uncomment the commented line and it would print:

I'm the parent.

I'm the child.

You should look for the concept of Polymorphism.

I found this page when I was trying to set the backgroundImage attribute of a div, but hadn't wrapped the backgroundImage value with url(). This worked fine:

for (var i=0; i<20; i++) {
  // add a wrapper around an image element
  var wrapper = document.createElement('div');
  wrapper.className = 'image-cell';

  // add the image element
  var img = document.createElement('div');
  img.className = 'image';
  img.style.backgroundImage = 'url(http://via.placeholder.com/350x150)';

  // add the image to its container; add both to the body
  wrapper.appendChild(img);
  document.body.appendChild(wrapper);
}

You can convert them to Set collections, and perform a set difference operation on them.

Like this:

Set<Date> ad = new HashSet<Date>(a);
Set<Date> bd = new HashSet<Date>(b);
ad.removeAll(bd);

Another way to accomplish this is a combination of Justus Thane's and mklement0's answers. It doesn't make sense to do it this way when you look at a one liner example, but when you're trying to mass-edit a file or a bunch of filenames it comes in pretty handy:

$test = '   One      for the money   '
$option = [System.StringSplitOptions]::RemoveEmptyEntries
$($test.split(' ',$option)).foreach{$_}

This will come out as:

One
for
the
money

Ok, that's an old question and it already have accepted answer by @siride, but that answer wasn't enough in my case, as --preserve-merges forces you to resolve all conflicts second time. My solution based on the idea by @Tobi B but with exact step-by-step commands

So we'll start on such state based on example in the question:

*   8101fe3 Merge branch 'topic'  [HEAD -> master]
|\  
| * b62cae6 2                     [topic]
| |
| | * f5a7ca8 5                   [origin/master]
| | * e7affba 4
| |/  
|/|   
* | eb3b733 3
|/  
* 38abeae 1

Note that we have 2 commits ahead master, so cherry-pick wouldn't work.

1. First of all, let's create correct history that we want:

   git checkout -b correct-history # create new branch to save master for future
   git rebase --strategy=ours --preserve-merges origin/master
   

   We use --preserve-merges to save our merge commit in history. We use --strategy=ours to ignore all merge conflicts as we don't care about what contents will be in that merge commit, we only need nice history now.

   History will looks like that (ignoring master):

   *   51984c7 Merge branch 'topic'  [HEAD -> correct-history]
   |\  
   | * b62cae6 2                     [topic]
   * | f5a7ca8 5                     [origin/master]
   * | e7affba 4
   * | eb3b733 3
   |/  
   * 38abeae 1
   

2. Let's get correct index now.

   git checkout master # return to our master branch
   git merge origin/master # merge origin/master on top of our master
   

   We may get some additional merge conflicts here, but that's would only be conflicts from files changed between 8101fe3 and f5a7ca8, but not includes already resolved conflicts from topic

   History will looks like this (ignoring correct-history):

   *   94f1484 Merge branch 'origin/master'  [HEAD -> master]
   |\  
   * | f5a7ca8 5                   [origin/master]
   * | e7affba 4
   | *   8101fe3 Merge branch 'topic'
   | |\  
   | | * b62cae6 2                     [topic]
   |/ /
   * / eb3b733 3
   |/  
   * 38abeae 1
   

3. The last stage is to combine our branch with correct history and branch with correct index

   git reset --soft correct-history
   git commit --amend
   

   We use reset --soft to reset our branch (and history) to correct-history, but leave index and working tree as is. Then we use commit --amend to rewrite our merge commit, that used to have incorrect index, with our good index from master.

   In the end we will have such state (note another id of top commit):

   *   13e6d03 Merge branch 'topic'  [HEAD -> master]
   |\  
   | * b62cae6 2                     [topic]
   * | f5a7ca8 5                     [origin/master]
   * | e7affba 4
   * | eb3b733 3
   |/  
   * 38abeae 1
   

I have created a small library to help with this: Library source on GitHub

<script src="dynamicListener.min.js"></script>
<script>
// Any `li` or element with class `.myClass` will trigger the callback, 
// even elements created dynamically after the event listener was created.
addDynamicEventListener(document.body, 'click', '.myClass, li', function (e) {
    console.log('Clicked', e.target.innerText);
});
</script>

The functionality is similar to jQuery.on().

The library uses the Element.matches() method to test the target element against the given selector. When an event is triggered the callback is only called if the target element matches the selector given.

I was having this issue building a SQL Server project on a CI/CD pipeline. In fact, I was having it locally as well, and I did not manage to solve it.

What worked for me was using an MSBuild SDK, capable of producing a SQL Server Data-Tier Application package (.dacpac) from a set of SQL scripts, which implies creating a new project. But I wanted to keep the SQL Server project, so that I could link it to the live database through SQL Server Object Explorer on Visual Studio. I took the following steps to have this up and running:

1. Kept my SQL Server project with the .sql database scripts.
2. Created a .NET Standard 2.0 class library project, making sure that the target framework was .NET Standard 2.0, as per the guidelines in the above link.

3. Set the contents of the .csproj as follows:

   <?xml version="1.0" encoding="utf-8"?>
   <Project Sdk="MSBuild.Sdk.SqlProj/1.0.0">
     <PropertyGroup>
       <SqlServerVersion>Sql140</SqlServerVersion>
       <TargetFramework>netstandard2.0</TargetFramework>
     </PropertyGroup>
   </Project>
   

4. I have chosen Sql140 as the SQL Server version because I am using SQL Server 2019. Check this answer to find out the mapping to the version you are using.

5. Ignore the SQL Server project on build, so that it stops breaking locally (it does build on Visual Studio, but it fails on VS Code).

6. Now we just have to make sure the .sql files are inside the SDK project when it is built. I achieved that with a simple powershell routine on the CI/CD pipeline that would copy the files from the SQL Server project to the SDK project:

Copy-Item -Path "Path.To.The.Database.Project\dbo\Tables\*" -Destination (New-item -Name "dbo\Tables" -Type Directory -Path "Path.To.The.DatabaseSDK.Project\")

PS: The files have to be physically in the SDK project, either in the root or on some folder, so links to the .sdk files in the SQL Server project won't work. In theory, it should be possible to copy these files with a pre-build condition, but for some obscure reason, this was not working for me. I tried also to have the .sql files on the SDK project and link them to the SQL Server project, but that would easily break the link with the SQL Server Object Explorer, so I decided to drop this as well.

You can do the following to install java 8 on your machine. First get the link of tar that you want to install. You can do this by:

1. go to java downloads page and find the appropriate download.
2. Accept the license agreement and download it.
3. In the download page in your browser right click and copy link address.

Then in your terminal:

$ cd /tmp
$ wget http://download.oracle.com/otn-pub/java/jdk/8u74-b02/jdk-8u74-linux-x64.tar.gz\?AuthParam\=1458001079_a6c78c74b34d63befd53037da604746c
$ tar xzf jdk-8u74-linux-x64.tar.gz?AuthParam=1458001079_a6c78c74b34d63befd53037da604746c
$ sudo mv jdk1.8.0_74 /opt
$ cd /opt/jdk1.8.0_74/
$ sudo update-alternatives --install /usr/bin/java java /opt/jdk1.8.0_91/bin/java 2
$ sudo update-alternatives --config java // select version
$ sudo update-alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_91/bin/jar 2
$ sudo update-alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_91/bin/javac 2
$ sudo update-alternatives --set jar /opt/jdk1.8.0_91/bin/jar
$ sudo update-alternatives --set javac /opt/jdk1.8.0_74/bin/javac
$ java -version // you should have the updated java

The idea it to use 2 Heaps viz one max heap and mean heap.

class Heap {
private Queue<Integer> low = new PriorityQueue<>(Comparator.reverseOrder());
private Queue<Integer> high = new PriorityQueue<>();

public void add(int number) {
    Queue<Integer> target = low.size() <= high.size() ? low : high;
    target.add(number);
    balance();
}

private void balance() {
    while(!low.isEmpty() && !high.isEmpty() && low.peek() > high.peek()) {
        Integer lowHead= low.poll();
        Integer highHead = high.poll();
        low.add(highHead);
        high.add(lowHead);
    }
}

public double median() {
    if(low.isEmpty() && high.isEmpty()) {
        throw new IllegalStateException("Heap is empty");
    } else {
        return low.size() == high.size() ? (low.peek() + high.peek()) / 2.0 : low.peek();
    }
}

}

the code behind for the window:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();
    }
}

The ViewModel:

public class ViewModelBase
{
    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>
    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

You get the warning because you did not assign a value to one, which is a pointer. This is undefined behavior.

You should declare it like this:

Vector* one = malloc(sizeof(Vector));

or like this:

Vector one;

in which case you need to replace -> operator with . like this:

one.a = 12;
one.b = 13;
one.c = -11;

Finally, in C99 and later you can use designated initializers:

Vector one = {
   .a = 12
,  .b = 13
,  .c = -11
};

It is possible to solve this problem using notepad++ by replacing Tabs with 4 Spaces:

1. Choose Search -> Find... or press Ctrl + F
2. Select the Replace tab
3. In the box named Search Mode choose Extended(\n, \r, \t, \0, \x...)
4. In the field Find what : write \t
5. In the field Replace with : press Space 4 times. Be sure that there is nothing else in this field.
6. Click on the button Replace All

An object can be a class, say you have a class called basketball.

but you want to have multiple basketballs so in your code you create more than 1 basketball

say basketball1 and basketball2. Then you run your application. You now have 2 instances of the object basketball.

    private static Double _MilesToKilometers = 1.609344;
    private static Double _MilesToNautical = 0.8684;


    /// <summary>
    /// Calculates the distance between two points of latitude and longitude.
    /// Great Link - http://www.movable-type.co.uk/scripts/latlong.html
    /// </summary>
    /// <param name="coordinate1">First coordinate.</param>
    /// <param name="coordinate2">Second coordinate.</param>
    /// <param name="unitsOfLength">Sets the return value unit of length.</param>
    public static Double Distance(Coordinate coordinate1, Coordinate coordinate2, UnitsOfLength unitsOfLength)
    {

        double theta = coordinate1.getLongitude() - coordinate2.getLongitude();
        double distance = Math.sin(ToRadian(coordinate1.getLatitude())) * Math.sin(ToRadian(coordinate2.getLatitude())) +
                       Math.cos(ToRadian(coordinate1.getLatitude())) * Math.cos(ToRadian(coordinate2.getLatitude())) *
                       Math.cos(ToRadian(theta));

        distance = Math.acos(distance);
        distance = ToDegree(distance);
        distance = distance * 60 * 1.1515;

        if (unitsOfLength == UnitsOfLength.Kilometer)
            distance = distance * _MilesToKilometers;
        else if (unitsOfLength == UnitsOfLength.NauticalMiles)
            distance = distance * _MilesToNautical;

        return (distance);

    }

I experienced this today. The value in Config was the updated one but the application would return the older value, stop and starting the solution did nothing.

So I cleared the .Net Temp folder.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

It shouldn't create bugs but to be safe close your solution down first. Clear the Temporary ASP.NET Files then load up your solution.

My issue was sorted.

Starting with your data frame DF, you could use the data.table package:

library(data.table)

## EDIT: As suggested by @MichaelChirico, setDT converts a
## data.frame to a data.table by reference and is preferred
## if you don't mind losing the data.frame
setDT(DF)

# EDIT: To get the column name 'Mean':

DF[, .(Mean = rowMeans(.SD)), by = ID]

#      ID     Mean
# [1,]  A 3.666667
# [2,]  B 4.333333
# [3,]  C 3.333333
# [4,]  D 4.666667
# [5,]  E 4.333333

PHP_EOL is a predefined constant in PHP since PHP 4.3.10 and PHP 5.0.2. See the manual posting:

Using this will save you extra coding on cross platform developments.

IE.

$data = 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);

If you looped through this twice you would see in 'somefile':

some data
some data

Use:

SELECT t1.Notes, 
       t2.Name
  FROM Table1 t1
  JOIN Table2 t2 ON t1.Notes LIKE CONCAT('%', t2.Name ,'%')

If you don't care about formatting and you just need some quick date, you can use this:

import time
print(time.ctime())

Use --build-arg in lower case environment variable:

docker build --build-arg http_proxy=http://proxy:port/ --build-arg https_proxy=http://proxy:port/ --build-arg ftp_proxy=http://proxy:port --build-arg no_proxy=localhost,127.0.0.1,company.com -q=false .

While @Timar's answer works perfectly for null default values (what was asked for), here another easy solution which allows other default values: Define an option interface as well as an according constant containing the defaults; in the constructor use the spread operator to set the options member variable

interface IXOptions {
    a?: string,
    b?: any,
    c?: number
}

const XDefaults: IXOptions = {
    a: "default",
    b: null,
    c: 1
}

export class ClassX {
    private options: IXOptions;

    constructor(XOptions: IXOptions) {
        this.options = { ...XDefaults, ...XOptions };
    }

    public printOptions(): void {
        console.log(this.options.a);
        console.log(this.options.b);
        console.log(this.options.c);
    }
}

Now you can use the class like this:

const x = new ClassX({ a: "set" });
x.printOptions();

Output:

set
null
1

var list1 = new List<Type1>();
var list2 = new List<Type2>();

list1.ForEach(item => list2.Add(new Type2() { Prop1 = value1 }));

Accuracy is also important.

What option 3 does is basically replace all the but any whitespaces with a +1 and then evaluates this to count up the 1's giving you the word count.

It's the most accurate and fastest method of the four that I've done here.

Please note it is slower than return str.split(" ").length; but it's accurate when compared to Microsoft Word.

See file ops/s and returned word count below.

I came across this code snippet that solves it.

//Creating a sample ArrayList 
List<Long> list = new ArrayList<Long>();

//Adding some long type values
list.add(100l);
list.add(200l);
list.add(300l);

//Converting the ArrayList to a Long
Long[] array = (Long[]) list.toArray(new Long[list.size()]);

//Printing the results
System.out.println(array[0] + " " + array[1] + " " + array[2]);

The conversion works as follows:

1. It creates a new Long array, with the size of the original list
2. It converts the original ArrayList to an array using the newly created one
3. It casts that array into a Long array (Long[]), which I appropriately named 'array'

It's far from pretty, but you could create a script or an alias that does something like this:

for c in $(git for-each-ref refs/tags/ --format='%(refname)'); do echo $c; git show --quiet "$c"; echo; done

Try:

In the controller:

ViewBag.Accounts= new SelectList(db.Accounts, "AccountId", "AccountName");

In the View:

@Html.DropDownList("AccountId", (IEnumerable<SelectListItem>)ViewBag.Accounts, null, new { @class ="form-control" })

or you can replace the "null" with whatever you want display as default selector, i.e. "Select Account".

To elaborate on Rahul Mahadik's answer, this works for MVC5 C#.NET:

AllowSameSiteAttribute.cs

public class AllowSameSiteAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var response = filterContext.RequestContext.HttpContext.Response;

        if(response != null)
        {
            response.AddHeader("Set-Cookie", "HttpOnly;Secure;SameSite=Strict");
            //Add more headers...
        }

        base.OnActionExecuting(filterContext);
    }
}

HomeController.cs

    [AllowSameSite] //For the whole controller
    public class UserController : Controller
    {
    }

or

    public class UserController : Controller
    {
        [AllowSameSite] //For the method
        public ActionResult Index()
        {
            return View();
        }
    }

What I would do is use the same trick often use for hovering on buttons. Prepare an image that has 2 parts: (1) a top half which is greyed out, meaning incomplete, and (2) a bottom half which is colored in, meaning completed. Use the same image 4 times to make up the 4 steps of the progress bar, and align top for incomplete steps, and align bottom for incomplete steps.

In order to take advantage of image alignment, you'd have to use the image as the background for 4 divs, rather than using the img element.

This is the CSS for background image alignment:

div.progress-incomplete {
  background-position: top;
}
div.progress-finished {
  background-position: bottom;
}

var result = from cx in CustomerList
         group cx by cx.GroupID into cxGroup
     orderby cxGroup.Key
     select cxGroup; 

foreach (var cxGroup in result) { 
Console.WriteLine(String.Format("GroupID = {0}", cxGroup.Key)); 
  foreach (var cx in cxGroup) { 
    Console.WriteLine(String.Format("\tUserID = {0}, UserName = {1}, GroupID = {2}", 
      new object[] { cx.ID, cx.Name, cx.GroupID })); 
  }
}

depending on how many columns there are, you could just name the columns, sans the ID, and manually add an ID or, if it's in your table, a secondary ID (sid):

insert into PROG(date, level, Percent, sid) select date, level, Percent, 55 from PROG where sid = 31 Here, if sid 31 has more than one resultant row, all of them will be copied over to sid 55 and your auto iDs will still get auto-generated. for ID only: insert into PROG(date, level, Percent, ID) select date, level, Percent, 55 from PROG where ID = 31 where 55 is the next available ID in the table and ID 31 is the one you want to copy.

I figured it out, and it should also work for other systems too. It's a variation of WW's answer.

select rate 
from d_payment_index
where fy = 2007
  and payment_year = 2008
  and program_id = 18
union
select 0 as rate 
from d_payment_index 
where not exists( select rate 
                  from d_payment_index
                  where fy = 2007
                    and payment_year = 2008
                    and program_id = 18 )

Differences between PUT and PATCH The main difference between PUT and PATCH requests is witnessed in the way the server processes the enclosed entity to update the resource identified by the Request-URI. When making a PUT request, the enclosed entity is viewed as the modified version of the resource saved on the original server, and the client is requesting to replace it. However, with PATCH, the enclosed entity boasts a set of instructions that describe how a resource stored on the original server should be partially modified to create a new version.

The second difference is when it comes to idempotency. HTTP PUT is said to be idempotent since it always yields the same results every after making several requests. On the other hand, HTTP PATCH is basically said to be non-idempotent. However, it can be made to be idempotent based on where it is implemented.

Since java.sql.Date extends java.util.Date, you should be able to do

java.util.Date newDate = result.getDate("VALUEDATE");

Use the substring method of the String class :

String removeCurrency=amount.getText().toString().substring(3);

The difference is primarily in deployment. Web forward and reverse proxies all have the same underlying features. They accept requests for HTTP requests in various formats and provide a response, usually by accessing the origin or contact server.

Fully featured servers usually have access control, caching, and some link-mapping features.

A forward proxy is a proxy that is accessed by configuring the client machine. The client needs protocol support for proxy features (redirection, proxy authentication, etc.). The proxy is transparent to the user experience, but not to the application.

A reverse proxy is a proxy that is deployed as a web server and behaves like a web server, with the exception that instead of locally composing the content from programs and disk, it forwards the request to an origin server. From the client perspective it is a web server, so the user experience is completely transparent.

In fact, a single proxy instance can run as a forward and reverse proxy at the same time for different client populations.

I was looking for a way to create a large dummy file with space allocation recently. All of the solutions look awkward. Finally I just started the DISKPART utility in Windows (embedded since Windows Vista):

DISKPART
CREATE VDISK FILE="C:\test.vhd" MAXIMUM=20000 TYPE=FIXED

Where MAXIMUM is the resulting file size, 20 GB here.

If this server is visible to the outside world, It's worth checking if it's having lots of requests to connect from the outside world (i.e. people trying to break into it)

No you cannot have multiple ids for a single tag, but I have seen a tag with a name attribute and an id attribute which are treated the same by some applications.

Here's some functional code (Java 8) which returns the x position of the right most edge of the right most screen. If no screens are found, then it returns 0.

  GraphicsDevice devices[];

  devices = GraphicsEnvironment.
     getLocalGraphicsEnvironment().
     getScreenDevices();

  return Stream.
     of(devices).
     map(GraphicsDevice::getDefaultConfiguration).
     map(GraphicsConfiguration::getBounds).
     mapToInt(bounds -> bounds.x + bounds.width).
     max().
     orElse(0);

Here are links to the JavaDoc.

GraphicsEnvironment.getLocalGraphicsEnvironment()
GraphicsEnvironment.getScreenDevices()
GraphicsDevice.getDefaultConfiguration()
GraphicsConfiguration.getBounds()

I know it's over a year old, but calling requestFeature() never solved my problem. In fact I don't call it at all.

It was an issue with inflating the view I suppose. Despite all my searching, I never found a suitable solution until I played around with the different methods of inflating a view.

AlertDialog.Builder is the easy solution but requires a lot of work if you use the onPrepareDialog() to update that view.

Another alternative is to leverage AsyncTask for dialogs.

A final solution that I used is below:

public class CustomDialog extends AlertDialog {

   private View content;

   public CustomDialog(Context context) {
       super(context);

       LayoutInflater li = LayoutInflater.from(context);
       content = li.inflate(R.layout.custom_view, null);

       setUpAdditionalStuff(); // do more view cleanup
       setView(content);           
   }

   private void setUpAdditionalStuff() {
       // ...
   }

   // Call ((CustomDialog) dialog).prepare() in the onPrepareDialog() method  
   public void prepare() {
       setTitle(R.string.custom_title);
       setIcon( getIcon() );
       // ...
   }
}

* Some Additional notes:

1. Don't rely on hiding the title. There is often an empty space despite the title not being set.
2. Don't try to build your own View with header footer and middle view. The header, as stated above, may not be entirely hidden despite requesting FEATURE_NO_TITLE.
3. Don't heavily style your content view with color attributes or text size. Let the dialog handle that, other wise you risk putting black text on a dark blue dialog because the vendor inverted the colors.

Here's what I've been doing to cope with the situation.

I use global imports on a new test class.

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;

When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:

import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;

This allows you to code away without getting 'stuck' trying to find the correct package to import.

Still having problems after following the solution provided by codegeek:
<link rel= "stylesheet" type= "text/css" href= "{{ url_for('static',filename='styles/mainpage.css') }}"> ?

In Google Chrome pressing the reload button (F5) will not reload the static files. If you have followed the accepted solution but still don't see the changes you have made to CSS, then press ctrl + shift + R to ignore cached files and reload the static files.

In Firefox pressing the reload button appears to reload the static files.

In Edge pressing the refresh button does not reload the static file. Pressing ctrl + shift + R is supposed to ignore cached files and reload the static files. However this does not work on my computer.

Put from before where, and order_by on last:

$this->db->select('*');
$this->db->from('courses');
$this->db->where('tennant_id',$tennant_id);
$this->db->order_by("UPPER(course_name)","desc");

Or try BINARY:

ORDER BY BINARY course_name DESC;

You should add manually on codeigniter for binary sorting.

And set "course_name" character column.

If sorting is used on a character type column, normally the sort is conducted in a case-insensitive fashion.

What type of structure data in courses table?

If you frustrated you can put into array and return using PHP:

Use natcasesort for order in "natural order": (Reference: http://php.net/manual/en/function.natcasesort.php)

Your array from database as example: $array_db = $result_from_db:

$final_result = natcasesort($array_db);

print_r($final_result);

To make POST request instead of GET request using urllib2, you need to specify empty data, for example:

import urllib2
req = urllib2.Request("http://am.domain.com:8080/openam/json/realms/root/authenticate?authIndexType=Module&authIndexValue=LDAP")
req.add_header('X-OpenAM-Username', 'demo')
req.add_data('')
r = urllib2.urlopen(req)

I'm quite a beginner in Python and I found the answer of Anand was very good but quite complicated to me, so I try to reformulate :

1) insert and append methods are not specific to sys.path and as in other languages they add an item into a list or array and :
* append(item) add item to the end of the list,
* insert(n, item) inserts the item at the nth position in the list (0 at the beginning, 1 after the first element, etc ...).

2) As Anand said, python search the import files in each directory of the path in the order of the path, so :
* If you have no file name collisions, the order of the path has no impact,
* If you look after a function already defined in the path and you use append to add your path, you will not get your function but the predefined one.

But I think that it is better to use append and not insert to not overload the standard behaviour of Python, and use non-ambiguous names for your files and methods.

Use namespace

using System.Collections.Specialized;

Make instance of DataContext Class

LinqToSqlDataContext dc = new LinqToSqlDataContext();

Use

OrderedDictionary dict = dc.TableName.ToDictionary(d => d.key, d => d.value);

In order to retrieve the values use namespace

   using System.Collections;

ICollection keyCollections = dict.Keys;
ICOllection valueCollections = dict.Values;

String[] myKeys = new String[dict.Count];
String[] myValues = new String[dict.Count];

keyCollections.CopyTo(myKeys,0);
valueCollections.CopyTo(myValues,0);

for(int i=0; i<dict.Count; i++)
{
Console.WriteLine("Key: " + myKeys[i] + "Value: " + myValues[i]);
}
Console.ReadKey();

For Xcode 7 (and possibly above),

go to Window -> Devices, 

hit the plus sign at the bottom and select the device connected and hit next, then Use for development.

This only works if Xcode is reading your device, but you aren't able to run your app on the device.

Also make sure the device's OS version is greater than or equal to your app's Deployment Target OS version.

Why not make it more general with BS 3? Just use "[something]modal" as the ID of the modal DIV.

$("div[id$='modal']").on('hidden.bs.modal',
    function () {
        $(this).removeData('bs.modal');
    }
);

Declare @MyInt int
Set @MyInt = ( Select Count(*) From MyTable )

If @MyInt > 0
Begin
    Print 'There''s something in the table'
End

I'm not sure if this is your issue, but you have to esacpe the single quote in the print statement with a second single quote. While you can use SELECT to populate the variable, using SET as you have done here is just fine and clearer IMO. In addition, you can be guaranteed that Count(*) will never return a negative value so you need only check whether it is greater than zero.

Found some different answers that I combined to solve simulair problem:

CREATE TABLE nummer (ID INTEGER PRIMARY KEY, num, text, text2);
WITH RECURSIVE
  for(i) AS (VALUES(1) UNION ALL SELECT i+1 FROM for WHERE i < 1000000)
INSERT INTO nummer SELECT i, i+1, "text" || i, "otherText" || i FROM for;

Adds 1 miljon rows with

• id increased by one every itteration
• num one greater then id
• text concatenated with id-number like: text1, text2 ... text1000000
• text2 concatenated with id-number like: otherText1, otherText2 ... otherText1000000

After I changed

defaultConfig {
    applicationId "com.example.bocheng.myapplication"
    minSdkVersion 15
    targetSdkVersion 'L' #change this to 19
    versionCode 1
    versionName "1.0"
}

in build.gradle file.

it works

Starting with Sql Server 2012: string concatenation function CONCAT converts to string implicitly. Therefore, another option is

SELECT Id AS 'PatientId',
       CONCAT(ParentId,'') AS 'ParentId'
FROM Patients

CONCAT converts null values to empty strings.

Some will consider this hacky, because it merely exploits a side effect of a function while the function itself isn't required for the task in hand.

Note : Make sure internet permission is given.

In android 9.0,

Webview or Imageloader can not load url or image because android 9 have network security issue which need to be enable by manifest file for all sub domain. so either you can add security config file.

1. Add @xml/network_security_config into your resources:

<network-security-config>_x000D_
    <domain-config cleartextTrafficPermitted="true">_x000D_
    <domain includeSubdomains="true">www.google.com</domain>_x000D_
    </domain-config>_x000D_
</network-security-config>

2. Add this security config to your Manifest like this:

<application_x000D_
   _x000D_
    android:networkSecurityConfig="@xml/network_security_config"_x000D_
    ...>_x000D_
</application>

if you want to allow all sub domain

<application_x000D_
   android:usesCleartextTraffic="true"_x000D_
    ...>_x000D_
</application>

Note: To solve the problem, don't use both of point 2 (android:networkSecurityConfig="@xml/network_security_config" and android:usesCleartextTraffic="true") choose one of them

This will work with iPad on Safari on iOS 7.1.x from my testing, I'm not sure about iOS 6 though. However, it will not work on Firefox. There is a jQuery plugin which aims to be cross browser compliant called jScrollPane.

Also, there is a duplicate post here on Stack Overflow which has some other details.

I find hardcoding(sic) "" every time for checking an empty string not as good.

Clean code approach

Doing this: foo == "" is very bad practice. "" is a magical value. You should never check against magical values (more commonly known as magical numbers)

What you should do is compare to a descriptive variable name.

Descriptive variable names

One may think that "empty_string" is a descriptive variable name. It isn't.

Before you go and do empty_string = "" and think you have a great variable name to compare to. This is not what "descriptive variable name" means.

A good descriptive variable name is based on its context. You have to think about what the empty string is.

• Where does it come from.
• Why is it there.
• Why do you need to check for it.

Simple form field example

You are building a form where a user can enter values. You want to check if the user wrote something or not.

A good variable name may be not_filled_in

This makes the code very readable

if formfields.name == not_filled_in:
    raise ValueError("We need your name")

Thorough CSV parsing example

You are parsing CSV files and want the empty string to be parsed as None

(Since CSV is entirely text based, it cannot represent None without using predefined keywords)

A good variable name may be CSV_NONE

This makes the code easy to change and adapt if you have a new CSV file that represents None with another string than ""

if csvfield == CSV_NONE:
    csvfield = None

There are no questions about if this piece of code is correct. It is pretty clear that it does what it should do.

Compare this to

if csvfield == EMPTY_STRING:
    csvfield = None

The first question here is, Why does the empty string deserve special treatment?

This would tell future coders that an empty string should always be considered as None.

This is because it mixes business logic (What CSV value should be None) with code implementation (What are we actually comparing to)

There needs to be a separation of concern between the two.

By my solution you can remove one or more than one item in an array thanks to pure JavaScript. There is no need for another JavaScript library.

var myArray = [1,2,3,4,5]; // First array

var removeItem = function(array,value) {  // My clear function
    if(Array.isArray(value)) {  // For multi remove
        for(var i = array.length - 1; i >= 0; i--) {
            for(var j = value.length - 1; j >= 0; j--) {
                if(array[i] === value[j]) {
                    array.splice(i, 1);
                };
            }
        }
    }
    else { // For single remove
        for(var i = array.length - 1; i >= 0; i--) {
            if(array[i] === value) {
                array.splice(i, 1);
            }
        }
    }
}

removeItem(myArray,[1,4]); // myArray will be [2,3,5]

Path of least resistance:

• Have a simple web project in mind.
• Go to rubyonrails.org and look at their "Blog in 15 minutes" screencast to get excited.
• Get a copy of O'Reilly Media's Learning Ruby
• Get a Mac or Linux box.
  (Fewer early Rails frustrations due to the fact that Rails is generally developed on these.)
• Get a copy of Agile Web Development with Rails.
• Get the version of Ruby and Rails described in that book.
• Run through that book's first section to get a feel for what it's like.
• Go to railscasts.com and view at the earliest videos for a closer look.
• Buy The Rails Way by Obie Fernandez to get a deeper understanding of Rails and what it's doing.
• Then upgrade to the newest production version of Rails, and view the latest railscasts.com videos.

Ideally we should do it from either controller or directive as per applicable. Use $anchorScroll, $location as dependency injection.

Then call this two method as

$location.hash('scrollToDivID');
$anchorScroll();

Here scrollToDivID is the id where you want to scroll.

Assumed you want to navigate to a error message div as

<div id='scrollToDivID'>Your Error Message</div>

Tested in Chrome38, IE11 and Firefox 33. Seems to have issues with Safari. However, Andrew got it working in Safari 8 on Mac OSx by switching to JPEG from PNG. For details, see his comment below.

When you are defining styles for division which is positioned absolutely, they specifying margins are useless. Because they are no longer inside the regular DOM tree.

You can use float to do the trick.

.divtagABS {
    float: left;
    margin-left: auto;  
    margin-right:auto;
 }

-XmxSIZE

For example: -Xmx1024M

Solution for pandas 0.24+ for converting numeric with missing values:

df = pd.DataFrame({'column name':[7500000.0,7500000.0, np.nan]})
print (df['column name'])
0    7500000.0
1    7500000.0
2          NaN
Name: column name, dtype: float64

df['column name'] = df['column name'].astype(np.int64)

ValueError: Cannot convert non-finite values (NA or inf) to integer

#http://pandas.pydata.org/pandas-docs/stable/user_guide/integer_na.html
df['column name'] = df['column name'].astype('Int64')
print (df['column name'])
0    7500000
1    7500000
2        NaN
Name: column name, dtype: Int64

I think you need cast to numpy.int64:

df['column name'].astype(np.int64)

Sample:

df = pd.DataFrame({'column name':[7500000.0,7500000.0]})
print (df['column name'])
0    7500000.0
1    7500000.0
Name: column name, dtype: float64

df['column name'] = df['column name'].astype(np.int64)
#same as
#df['column name'] = df['column name'].astype(pd.np.int64)
print (df['column name'])
0    7500000
1    7500000
Name: column name, dtype: int64

If some NaNs in columns need replace them to some int (e.g. 0) by fillna, because type of NaN is float:

df = pd.DataFrame({'column name':[7500000.0,np.nan]})

df['column name'] = df['column name'].fillna(0).astype(np.int64)
print (df['column name'])
0    7500000
1          0
Name: column name, dtype: int64

Also check documentation - missing data casting rules

EDIT:

Convert values with NaNs is buggy:

df = pd.DataFrame({'column name':[7500000.0,np.nan]})

df['column name'] = df['column name'].values.astype(np.int64)
print (df['column name'])
0                7500000
1   -9223372036854775808
Name: column name, dtype: int64

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

In Express 4.x you can use req.hostname, which returns the domain name, without port. i.e.:

// Host: "example.com:3000"
req.hostname
// => "example.com"

See: http://expressjs.com/en/4x/api.html#req.hostname

I like putting the inputs inside the labels (added bonus: now you don't need the for attribute on the label), and put vertical-align: middle on the input.

label > input[type=radio] {_x000D_
    vertical-align: middle;_x000D_
    margin-top: -2px;_x000D_
}_x000D_
_x000D_
#d2 {  _x000D_
    font-size: 30px;_x000D_
}

<div>_x000D_
 <label><input type="radio" name="radio" value="1">Good</label>_x000D_
 <label><input type="radio" name="radio" value="2">Excellent</label>_x000D_
<div>_x000D_
<br>_x000D_
<div id="d2">_x000D_
 <label><input type="radio" name="radio2" value="1">Good</label>_x000D_
 <label><input type="radio" name="radio2" value="2">Excellent</label>_x000D_
<div>

(The -2px margin-top is a matter of taste.)

Another option I really like is using a table. (Hold your pitch forks! It's really nice!) It does mean you need to add the for attribute to all your labels and ids to your inputs. I'd recommended this option for labels with long text content, over multiple lines.

<table><tr><td>_x000D_
    <input id="radioOption" name="radioOption" type="radio" />_x000D_
    </td><td>_x000D_
    <label for="radioOption">                     _x000D_
        Really good option_x000D_
    </label>_x000D_
</td></tr></table>

You're misinterpreting what the onchange event does when applied to a textarea. It won't fire until it loses focus or you hit enter. Why not fire the function from an onchange on the select that fills in the text area?

Check out here for more on the onchange event: w3schools

try this :

public class vm
{
  public static void main(String[] args)
  {
      System.getProperty("sun.arch.data.model") 
  }
}

compile and run. it will return either 32 or 64 as per your java version . . .

For me, the server was expect HTTPS requests, but I didn't specify that in the URL. The hook would reach the server, but the body would be empty.

More efficient (faster) to use Buffer.BlockCopy over Array.CopyTo,

int[] x = new int [] { 1, 2, 3};
int[] y = new int [] { 4, 5 };

int[] z = new int[x.Length + y.Length];
var byteIndex = x.Length * sizeof(int);
Buffer.BlockCopy(x, 0, z, 0, byteIndex);
Buffer.BlockCopy(y, 0, z, byteIndex, y.Length * sizeof(int));

I wrote a simple test program that "warms up the Jitter", compiled in release mode and ran it without a debugger attached, on my machine.

For 10,000,000 iterations of the example in the question

Concat took 3088ms

CopyTo took 1079ms

BlockCopy took 603ms

If I alter the test arrays to two sequences from 0 to 99 then I get results similar to this,

Concat took 45945ms

CopyTo took 2230ms

BlockCopy took 1689ms

From these results I can assert that the CopyTo and BlockCopy methods are significantly more efficient than Concat and furthermore, if performance is a goal, BlockCopy has value over CopyTo.

To caveat this answer, if performance doesn't matter, or there will be few iterations choose the method you find easiest. Buffer.BlockCopy does offer some utility for type conversion beyond the scope of this question.

I resolved the issue by converting the source feed from http://www.news18.com/rss/politics.xml to https://www.news18.com/rss/politics.xml

with http below code was creating an empty file which was causing the issue down the line

    String feedUrl = "https://www.news18.com/rss/politics.xml"; 
    File feedXmlFile = null;

    try {
    feedXmlFile =new File("C://opinionpoll/newsFeed.xml");
    FileUtils.copyURLToFile(new URL(feedUrl),feedXmlFile);


          DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
          DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
          Document doc = dBuilder.parse(feedXmlFile);

    // Once finished with the bitmap objects, we deallocate them.
    originalBMP.Dispose();

    bannerBMP.Dispose();
    oGraphics.Dispose();

This is a programming style that you'll regret sooner or later. Sooner is knocking on the door, you forgot one. You are not disposing newBitmap. Which keeps a lock on the file until the garbage collector runs. If it doesn't run then the second time you try to save to the same file you'll get the klaboom. GDI+ exceptions are too miserable to give a good diagnostic so serious head-scratching ensues. Beyond the thousands of googlable posts that mention this mistake.

Always favor using the using statement. Which never forgets to dispose an object, even if the code throws an exception.

using (var newBitmap = new Bitmap(thumbBMP)) {
    newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
}

Albeit that it is very unclear why you even create a new bitmap, saving thumbBMP should already be good enough. Anyhoo, give the rest of your disposable objects the same using love.

Using jdk7-u221, I was need to install the Java Cryptography Extension (JCE)

Java Cryptography Extension JCE

Chkconfig is no longer available in Ubuntu.

Chkconfig is a script. You can download it from here.

Like Robert Nishihara mentioned, Apache Arrow makes this easy, specifically with the Plasma in-memory object store, which is what Ray is built on.

I made brain-plasma specifically for this reason - fast loading and reloading of big objects in a Flask app. It's a shared-memory object namespace for Apache Arrow-serializable objects, including pickle'd bytestrings generated by pickle.dumps(...).

The key difference with Apache Ray and Plasma is that it keeps track of object IDs for you. Any processes or threads or programs that are running on locally can share the variables' values by calling the name from any Brain object.

$ pip install brain-plasma

$ plasma_store -m 10000000 -s /tmp/plasma

from brain_plasma import Brain
brain = Brain(path='/tmp/plasma/)

brain['a'] = [1]*10000

brain['a']
# >>> [1,1,1,1,...]

I guess you should install CA certificate form one if authority canter:

ssl_trusted_certificate ssl/SSL_CA_Bundle.pem;

Or try to update node:

brew upgrade node

If it is installed with brew (like in my case). sudo npm update -g npm did not solve the "same" problem for me.

From MySQL 5.7 documentation

MySQL 5.7.5 and up implements detection of functional dependence. If the ONLY_FULL_GROUP_BY SQL mode is enabled (which it is by default), MySQL rejects queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are functionally dependent on them.

This means that @Jader Dias's solution wouldn't work everywhere.

Here is a solution that would work when ONLY_FULL_GROUP_BY is enabled:

SET @row := NULL;
SELECT
    SomeColumn,
    AnotherColumn
FROM (
    SELECT
        CASE @id <=> SomeColumn AND @row IS NOT NULL 
            WHEN TRUE THEN @row := @row+1 
            ELSE @row := 0 
        END AS rownum,
        @id := SomeColumn AS SomeColumn,
        AnotherColumn
    FROM
        SomeTable
    ORDER BY
        SomeColumn, -AnotherColumn DESC
) _values
WHERE rownum = 0
ORDER BY SomeColumn;

It sounds like some of your styles are being reset.

By default in most browsers, uls and ols have margin and padding added to them.

You can override this (and many do) by adding a line to your css like so

ul, ol {  //THERE MAY BE OTHER ELEMENTS IN THE LIST
    margin:0;
    padding:0;
}

In this case, you would remove the element from this list or add a margin/padding back, like so

ul{
    margin:1em;
}

As per the question, i have listed the answers in javascript

By Selecting TagName

document.getElementsByTagName('textarea')[0].style.resize = "none";

By Selecting Id

document.getElementById('textArea').style.resize = "none";

munmap(0xb7d28000, 4096) = 0
write(2, "OSError", 7) = 7

I've seen sloppy code that looks like this:

serrno = errno;
some_Syscall(...)
if (serrno != errno)
/* sound alarm: CATROSTOPHIC ERROR !!! */

You should check to see if this is what is happening in the python code. Errno is only valid if the proceeding system call failed.

Edited to add:

You don't say how long this process lives. Possible consumers of memory

• forked processes
• unused data structures
• shared libraries
• memory mapped files

You don't need the jsp:useBean to set the model if you already have a controller which prepared the model.

Just access it plain by EL:

<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>

or by JSTL <c:out> tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:

<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>

See also:

• Our Servlets wiki page

Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.

session.setAttribute("questions", questions);

and alter EL accordingly to use ${questions}.

Also note that you don't have any JSTL tag in your code. It's all plain JSP.

Given a first selector: SelectorA, you can find the next match of SelectorB as below:

Example with mouseover to change border-with:

$("SelectorA").on("mouseover", function() {
    var i = $(this).find("SelectorB")[0];
    $(i).css({"border" : "1px"});
    });
}

General use example to change border-with:

var i = $("SelectorA").find("SelectorB")[0];
$(i).css({"border" : "1px"});

1. Install Java 7u21 from here: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jdk-7u21-oth-JPR

2. set these variables:

   export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home"
   export PATH=$JAVA_HOME/bin:$PATH
   

3. Run your app and fun :)

(Minor update: put variable value in quote)

Hi for example if you have split and replace in String 07:05:45PM

var hour = time.replace("PM", "").split(":");

Result

[ '07', '05', '45' ]

You have to load jdbc driver. Consider below Code.

try {
           Class.forName("com.mysql.jdbc.Driver");

            // connect way #1
            String url1 = "jdbc:mysql://localhost:3306/aavikme";
            String user = "root";
            String password = "aa";

            conn1 = DriverManager.getConnection(url1, user, password);
            if (conn1 != null) {
                System.out.println("Connected to the database test1");
            }

            // connect way #2
            String url2 = "jdbc:mysql://localhost:3306/aavikme?user=root&password=aa";
            conn2 = DriverManager.getConnection(url2);
            if (conn2 != null) {
                System.out.println("Connected to the database test2");
            }

            // connect way #3
            String url3 = "jdbc:mysql://localhost:3306/aavikme";
            Properties info = new Properties();
            info.put("user", "root");
            info.put("password", "aa");

            conn3 = DriverManager.getConnection(url3, info);
            if (conn3 != null) {
                System.out.println("Connected to the database test3");
            }
   } catch (SQLException ex) {
            System.out.println("An error occurred. Maybe user/password is invalid");
            ex.printStackTrace();
   } catch (ClassNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }

The new Chosen libraries don't use the liszt. I used the following:

document.getElementById('autoship_option').selectedIndex = 0;
$("#autoship_option").trigger("chosen:updated");

if ($("input[name='html_elements']:checked").size()==0) {
   alert('Nothing is checked!');
}
else {
  alert('One of the radio buttons is checked!');
}

It's better to use throw instead of throw ex.

throw ex reset the original stack trace and can't be found the previous stack trace.

If we use throw, we will get a full stack trace.

in 2019 I need to write minified jquery plugins so I need it too this alias and so testing these examples and others ,from other sources,I found a way without copy in the memory of whe entire object ,but creating only a reference. I tested this already with firefox and watching task manager's tab memory on firefox before. The code is:

var {p: d} ={p: document};
console.log(d.body);

This is my recipe

Note: This isn't exactly what OP is asking. These instructions will help you change the colors of items (comments, keywords, etc) that are defined syntax matching rules. For example, use these instructions to change so that all code comments are colored blue instead of green.

I believe the OP is asking how to define this as an item to be colored when found in a JavaScript source file.

1. Install Package: PackageResourceViewer

2. Ctrl+Shift+P > [PackageResourceViewer: Open Resource] > [Color Scheme - Default] > [Marina.sublime-color-scheme] (or whichever color scheme you use)

3. The above command will open a new tab to the file "Marina.sublime-color-scheme".

   • For me, this file was located in my roaming profile %appdata% (C:\Users\walter\AppData\Roaming\Sublime Text 3\Packages\Color Scheme - Default\) .
   • However, if I browse to that path in Windows Explorer, [Color Scheme - Default] is not of a child-dir of [Packages] dir. I suspect that PackageResourceViewer is doing some virtualization.

optional step: On the new color-scheme tab: Ctrl+Shift+P > [Set Syntax: JSON]

4. Search for the rule you want to change. I wanted to make comments be move visible, so I searched for "Comment"

   • I found it in the "rules" section

 "rules":
    [
        {
            "name": "Comment",
            "scope": "comment, punctuation.definition.comment",
            "foreground": "var(blue6)"
        },

5. Search for the string "blue6": to find the color variable definitions section. I found it in the "variables" section.

6. Pick a new color using a tool like http://hslpicker.com/ .

7. Either define a new color variable, or overwrite the color setting for blue6.

   • Warning: overwriting blue6 will affect all other text-elements in that color scheme which also use blue6 ("Punctuation" "Accessor").

8. Save your file, the changes will be applied instantly to any open files/tabs.

NOTES

Sublime will handle any of these color styles. Possibly more.

hsla = hue, saturation, lightness, alpha rgba = red, green, blue, alpha

hsla(151, 100%, 41%, 1) - last param is the alpha level (transparency) 1 = opaque, 0.5 = half-transparent, 0 = full-transparent

hsl(151, 100%, 41%) - no alpha channel

rgba(0, 209, 108, 1) - rgb with an alpha channel

rgb(0, 209, 108) - no alpha channel

I'd prefer to normalize your table structure more, something like;

COMMENTS
-------
id (pk)
title
comment
userId


USERS
-----
id (pk)
name
email


COMMENT_VOTE
------------
commentId (pk)
userId (pk)
rating (float)

Now it's easier to maintain! And MySQL only accept one vote per user and comment.

The algorithms with m-n can runs awfully long.

This one performs much better:

def gcd(x, y):
    while y != 0:
        (x, y) = (y, x % y)
    return x

line-height does fix it, but you might have to make it pretty large: on my setttings I have to increase line-height to about 1.8 before the <sup> no longer interferes with it, but this will vary from font to font.

One possible approach to get consistent line heights is to set your own superscript styling instead of the default vertical-align: super. If you use top it won't add anything to the line box, but you may have to reduce font size further to make it fit:

sup { vertical-align: top; font-size: 0.6em; }

Another hack you could try is to use positioning to move it up a bit without affecting the line box:

sup { vertical-align: top; position: relative; top: -0.5em; }

Of course this runs the risk of crashing into the line above if you don't have enough line-height.

To get this in a ListFragment:

getListView().setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL); 
getListView().setStackFromBottom(true);`

Added this answer because if someone do a google search for same problem with ListFragment he just finds this..

It's a good practice to make all the images in vector based format so you can resize them easily using a vector design software like Illustrator etc..

Basically you have two options

scale_x_continuous(limits = c(-5000, 5000))

or

coord_cartesian(xlim = c(-5000, 5000)) 

Where the first removes all data points outside the given range and the second only adjusts the visible area. In most cases you would not see the difference, but if you fit anything to the data it would probably change the fitted values.

You can also use the shorthand function xlim (or ylim), which like the first option removes data points outside of the given range:

+ xlim(-5000, 5000)

For more information check the description of coord_cartesian.

The RStudio cheatsheet for ggplot2 makes this quite clear visually. Here is a small section of that cheatsheet:

Distributed under CC BY.

The simple way to do that is to use git format-patch.

Assume we have 2 git repositories foo and bar.

foo contains:

• foo.txt
• .git

bar contains:

• bar.txt
• .git

and we want to end-up with foo containing the bar history and these files:

• foo.txt
• .git
• foobar/bar.txt

So to do that:

 1. create a temporary directory eg PATH_YOU_WANT/patch-bar
 2. go in bar directory
 3. git format-patch --root HEAD --no-stat -o PATH_YOU_WANT/patch-bar --src-prefix=a/foobar/ --dst-prefix=b/foobar/
 4. go in foo directory
 5. git am PATH_YOU_WANT/patch-bar/*

And if we want to rewrite all message commits from bar we can do, eg on Linux:

git filter-branch --msg-filter 'sed "1s/^/\[bar\] /"' COMMIT_SHA1_OF_THE_PARENT_OF_THE_FIRST_BAR_COMMIT..HEAD

This will add "[bar] " at the beginning of each commit message.

e.currentTarget is element(parent) where event is registered, e.target is node(children) where event is pointing to.

There is still another way to do it, which is using a particular NamingStrategy, which can be applied to a class or a property by decorating them with [JSonObject] or [JsonProperty].

There are predefined naming strategies like CamelCaseNamingStrategy, but you can implement your own ones.

The implementation of different naming strategies can be found here: https://github.com/JamesNK/Newtonsoft.Json/tree/master/Src/Newtonsoft.Json/Serialization

I agree with alex about making sure the DOM is loaded. I also think that the submit button will trigger a refresh.

This is what I would do

<html>
<head>
<title>webpage</title>
</head>
<script type="text/javascript">
var myButton;
var myTextfield;

function setup() {
  myButton = document.getElementById("myButton");
  myTextfield = document.getElementById("myTextfield");
  myButton.onclick = function() {
    var userName = myTextfield.value;
    greetUser(userName);
    return false;
  }
}

function greetUser(userName) {
  var greeting = "Hello " + userName + "!";
  document.getElementsByTagName("h2")[0].innerHTML = greeting;
}

</script>
<body onload="setup()">
  <h2>Hello World!</h2>
  <p id="myParagraph">This is an example website</p>

  <form>
    <input type="text" id="myTextfield" placeholder="Type your name" />
    <input type="button" id="myButton" value="Go" />
  </form>
  </body>
</html>

have fun!

Found an alternative way to download cocoapods is to download one of the snapshots available here. It is a bit old but the .bz2 compressed file was much faster to download. Once I had downloaded it, I copied it over to ~/.cocoapods/repos/ and then I unzipped it using bzip2 -dk *.bz2.

The unzipping took a while and once it was over, I changed the extension of the newly uncompressed file to .tar and did tar xvf *.tar to unzip that. This will show the list of files being created and will also take a while.

Finally when I ran pod repo list while inside the project folder, it showed the master folder had been added as a repo. Because I still kept getting an error that it was unable to find the specification for the pod I was looking for, I went to the master folder and did git fetch and then git merge. The git fetch took the longest, about an hour at 50 KB/s. I used fetch and merge instead of pull, as I was having issues with it, i.e. fatal: the remote end hung up unexpectedly. It is now up to date and I was able to get the pod I wanted.

There are a couple of things wrong in this code:

1. You're using <input> the wrong way. You should use a <label> if you want to make the text behind it clickable.
2. It's setting the enabled attribute, which does not exist. Use disabled instead.
3. If it would be an attribute, it's value should not be false, use disabled="disabled" or simply disabled without a value.
4. If checking for someone clicking on a form event that will CHANGE it's value (like check-boxes and radio-buttons), use .change() instead.

I'm not sure what your code is supposed to do. My guess is that you want to disable the input field with class roomNumber once someone selects "Walk in" (and possibly re-enable when deselected). If so, try this code:

HTML:

<form class="type">
    <p>
        <input type="radio" name="type" checked="checked" id="guest" value="guest" />
        <label for="guest">In House</label>
    </p>
    <p>
        <input type="radio" name="type" id="walk_in" value="walk_in" />
        <label for="walk_in">Walk in</label>
    </p>
    <p>
        <input type="text" name="roomnumber" class="roomNumber" value="12345" />
    </p>
</form>

Javascript:

$("form input:radio").change(function () {
    if ($(this).val() == "walk_in") {
        // Disable your roomnumber element here
        $('.roomNumber').attr('disabled', 'disabled');
    } else {
        // Re-enable here I guess
        $('.roomNumber').removeAttr('disabled');
    }
});

I created a fiddle here: http://jsfiddle.net/k28xd/1/

Above answers are correct. But simply this worked for me

One of the Roslyn engineers who specializes in understanding optimization of stack usage took a look at this and reports to me that there seems to be a problem in the interaction between the way the C# compiler generates local variable stores and the way the JIT compiler does register scheduling in the corresponding x86 code. The result is suboptimal code generation on the loads and stores of the locals.

For some reason unclear to all of us, the problematic code generation path is avoided when the JITter knows that the block is in a try-protected region.

This is pretty weird. We'll follow up with the JITter team and see whether we can get a bug entered so that they can fix this.

Also, we are working on improvements for Roslyn to the C# and VB compilers' algorithms for determining when locals can be made "ephemeral" -- that is, just pushed and popped on the stack, rather than allocated a specific location on the stack for the duration of the activation. We believe that the JITter will be able to do a better job of register allocation and whatnot if we give it better hints about when locals can be made "dead" earlier.

Thanks for bringing this to our attention, and apologies for the odd behaviour.

The easiest way i found was to create a tiny javascript function tied to your form :

function enablePath() {
    document.getElementById('select_name').disabled= "";
}

and you call it in your form here :

<form action="act.php" method="POST" name="form_name" onSubmit="enablePath();">

Or you can call it in the function you use to check your form :)

To hide the prompt set xls.DisplayAlerts = False

ConflictResolution is not a true or false property, it should be xlLocalSessionChanges

Note that this has nothing to do with displaying the Overwrite prompt though!

Set xls = CreateObject("Excel.Application")    
xls.DisplayAlerts = False
Set wb = xls.Workbooks.Add
fullFilePath = importFolderPath & "\" & "A.xlsx"

wb.SaveAs fullFilePath, AccessMode:=xlExclusive,ConflictResolution:=Excel.XlSaveConflictResolution.xlLocalSessionChanges    
wb.Close (True)

Actually this will give you repeated indices np.random.random_integers(0, len(df), N) where N is a large number.

 SELECT * from
 (
 select m.*, rownum r
 from maps006 m
 )
 where r > 49 and r < 101

Also, consider GForge.

No expensive forks, no pipes, no bashisms:

$ set -- $STRING
$ eval echo \${$N}
three

But beware of globbing.

You can try this:

   $mytimestamp = 1465298940;

   echo gmdate("m-d-Y", $mytimestamp);

Output :

06-07-2016

I believe that I have the simplest answer yet using Spring Boot 1.4, included imports for the test class.:

There is HTML entity &#10003 but it doesn't work in some older browsers.

• The try block will execute a sensitive code which can throw exceptions
• The catch block will be used whenever an exception (of the type caught) is thrown in the try block
• The finally block is called in every case after the try/catch blocks. Even if the exception isn't caught or if your previous blocks break the execution flow.
• The throw keyword will allow you to throw an exception (which will break the execution flow and can be caught in a catch block).
• The throws keyword in the method prototype is used to specify that your method might throw exceptions of the specified type. It's useful when you have checked exception (exception that you have to handle) that you don't want to catch in your current method.

On another note, you should really accept some answers. If anyone encounter the same problems as you and find your questions, he/she will be happy to directly see the right answer to the question.

First composer requires doctrine/dbal, then:

$table->longText('column_name')->change();

Here is a complete example. It tries to get the country code from TelephonyManager (from SIM or CDMA devices), and if not available, tries to get it from the local configuration.

private static String getDeviceCountryCode(Context context) {
    String countryCode;

    // Try to get country code from TelephonyManager service
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    if(tm != null) {
        // Query first getSimCountryIso()
        countryCode = tm.getSimCountryIso();
        if (countryCode != null && countryCode.length() == 2)
            return countryCode.toLowerCase();

        if (tm.getPhoneType() == TelephonyManager.PHONE_TYPE_CDMA) {
            // Special case for CDMA Devices
            countryCode = getCDMACountryIso();
        }
        else {
            // For 3G devices (with SIM) query getNetworkCountryIso()
            countryCode = tm.getNetworkCountryIso();
        }

        if (countryCode != null && countryCode.length() == 2)
            return countryCode.toLowerCase();
    }

    // If network country not available (tablets maybe), get country code from Locale class
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        countryCode = context.getResources().getConfiguration().getLocales().get(0).getCountry();
    }
    else {
        countryCode = context.getResources().getConfiguration().locale.getCountry();
    }

    if (countryCode != null && countryCode.length() == 2)
        return  countryCode.toLowerCase();

    // General fallback to "us"
    return "us";
}

@SuppressLint("PrivateApi")

        Class<?> systemProperties = Class.forName("android.os.SystemProperties");
        Method get = systemProperties.getMethod("get", String.class);

        // Get homeOperator that contain MCC + MNC
        String homeOperator = ((String) get.invoke(systemProperties,
                "ro.cdma.home.operator.numeric"));

        // First three characters (MCC) from homeOperator represents the country code

    catch (NullPointerException ignored) {
    }

    return null;
}

Also another idea is to try an API request like in this answer.

References are here and here.

try

raw_input('Enter your input:')  # If you use Python 2
input('Enter your input:')      # If you use Python 3

and if you want to have a numeric value just convert it:

try:
    mode=int(raw_input('Input:'))
except ValueError:
    print "Not a number"

You might often find

cond and on_true or on_false

but this lead to problem when on_true == 0

>>> x = 0
>>> print x == 0 and 0 or 1 
1
>>> x = 1
>>> print x == 0 and 0 or 1 
1

where you would expect for a normal ternary operator this result

>>> x = 0
>>> print 0 if x == 0 else 1 
0
>>> x = 1
>>> print 0 if x == 0 else 1 
1

mysql->SHOW PROCESSLIST;
kill xxxx; 

and then kill which one in sleep. In my case it is 2456.

var rad_id = document.getElementById('<%=radio_btn_lst.ClientID %>');
var radio = rad_id.getElementsByTagName("input");
radio[0].checked = true;

//this for javascript in asp.net try this in .aspx page

// if you select other radiobutton increase [0] to [1] or [2] like this

Little sum up for searching by row:

This can be useful if you don't know the column values ??or if columns have non-numeric values

if u want get index number as integer u can also do:

item = df[4:5].index.item()
print(item)
4

it also works in numpy / list:

numpy = df[4:7].index.to_numpy()[0]
lista = df[4:7].index.to_list()[0]

in [x] u pick number in range [4:7], for example if u want 6:

numpy = df[4:7].index.to_numpy()[2]
print(numpy)
6

for DataFrame:

df[4:7]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449

or:

df[(df.index>=4) & (df.index<7)]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449   

Use This as the solution

This worked for me perfectly..

The ApplicationPoolIdentity is assigned membership of the Users group as well as the IIS_IUSRS group. On first glance this may look somewhat worrying, however the Users group has somewhat limited NTFS rights.

For example, if you try and create a folder in the C:\Windows folder then you'll find that you can't. The ApplicationPoolIdentity still needs to be able to read files from the windows system folders (otherwise how else would the worker process be able to dynamically load essential DLL's).

With regard to your observations about being able to write to your c:\dump folder. If you take a look at the permissions in the Advanced Security Settings, you'll see the following:

See that Special permission being inherited from c:\:

That's the reason your site's ApplicationPoolIdentity can read and write to that folder. That right is being inherited from the c:\ drive.

In a shared environment where you possibly have several hundred sites, each with their own application pool and Application Pool Identity, you would store the site folders in a folder or volume that has had the Users group removed and the permissions set such that only Administrators and the SYSTEM account have access (with inheritance).

You would then individually assign the requisite permissions each IIS AppPool\[name] requires on it's site root folder.

You should also ensure that any folders you create where you store potentially sensitive files or data have the Users group removed. You should also make sure that any applications that you install don't store sensitive data in their c:\program files\[app name] folders and that they use the user profile folders instead.

So yes, on first glance it looks like the ApplicationPoolIdentity has more rights than it should, but it actually has no more rights than it's group membership dictates.

An ApplicationPoolIdentity's group membership can be examined using the SysInternals Process Explorer tool. Find the worker process that is running with the Application Pool Identity you're interested in (you will have to add the User Name column to the list of columns to display:

For example, I have a pool here named 900300 which has an Application Pool Identity of IIS APPPOOL\900300. Right clicking on properties for the process and selecting the Security tab we see:

As we can see IIS APPPOOL\900300 is a member of the Users group.

I suspect the problem is that you've put the "-D" after the -jar. Try this:

java -Dtest="true" -jar myApplication.jar

From the command line help:

java [-options] -jar jarfile [args...]

In other words, the way you've got it at the moment will treat -Dtest="true" as one of the arguments to pass to main instead of as a JVM argument.

(You should probably also drop the quotes, but it may well work anyway - it probably depends on your shell.)

 public static <E> E[] arrayListToTypedArray(List<E> list) {

    if (list == null) {
      return null;
    }
    int noItems = list.size();
    if (noItems == 0) {
      return null;
    }

    E[] listAsTypedArray;
    E typeHelper = list.get(0);

    try {
      Object o = Array.newInstance(typeHelper.getClass(), noItems);
      listAsTypedArray = (E[]) o;
      for (int i = 0; i < noItems; i++) {
        Array.set(listAsTypedArray, i, list.get(i));
      }
    } catch (Exception e) {
      return null;
    }

    return listAsTypedArray;
  }

I'm not sure about what you mean by "I have no access to image" But if you have access to parent div you can do the following:

Firs give id or class to your div:

<div class="parent">
   <img src="http://someimage.jpg">
</div>

Than add this to your css:

.parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 100%;
   width: 100%;
}

An Int-based pow function that computes the value directly via bit shift for base 2 in Swift 5:

func pow(base: Int, power: UInt) -> Int {
    if power == 0 { return 1 }
    // for base 2, use a bit shift to compute the value directly
    if base == 2 { return 2 << Int(power - 1) }
    // otherwise multiply base repeatedly to compute the value
    return repeatElement(base, count: Int(power)).reduce(1, *)
}

(Make sure the result is within the range of Int - this does not check for the out of bounds case)

My own implementation of generic restTemplate call:

private <REQ, RES> RES queryRemoteService(String url, HttpMethod method, REQ req, Class reqClass) {
    RES result = null;
    try {
        long startMillis = System.currentTimeMillis();

        // Set the Content-Type header
        HttpHeaders requestHeaders = new HttpHeaders();
        requestHeaders.setContentType(new MediaType("application","json"));            

        // Set the request entity
        HttpEntity<REQ> requestEntity = new HttpEntity<>(req, requestHeaders);

        // Create a new RestTemplate instance
        RestTemplate restTemplate = new RestTemplate();

        // Add the Jackson and String message converters
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
        restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

        // Make the HTTP POST request, marshaling the request to JSON, and the response to a String
        ResponseEntity<RES> responseEntity = restTemplate.exchange(url, method, requestEntity, reqClass);
        result = responseEntity.getBody();
        long stopMillis = System.currentTimeMillis() - startMillis;

        Log.d(TAG, method + ":" + url + " took " + stopMillis + " ms");
    } catch (Exception e) {
         Log.e(TAG, e.getMessage());
    }
    return result;
}

To add some context, I'm consuming RESTful service with this, hence all requests and responses are wrapped into small POJO like this:

public class ValidateRequest {
  User user;
  User checkedUser;
  Vehicle vehicle;
}

and

public class UserResponse {
  User user;
  RequestResult requestResult;
}

Method which calls this is the following:

public User checkUser(User user, String checkedUserName) {
    String url = urlBuilder()
            .add(USER)
            .add(USER_CHECK)
            .build();

    ValidateRequest request = new ValidateRequest();
    request.setUser(user);
    request.setCheckedUser(new User(checkedUserName));

    UserResponse response = queryRemoteService(url, HttpMethod.POST, request, UserResponse.class);
    return response.getUser();
}

And yes, there's a List dto-s as well.

K = 32.44
FSPL = Ptx - CLtx + AGtx + AGrx - CLrx - Prx - FM
d = 10 ^ (( FSPL - K - 20 log10( f )) / 20 )

Here:

• K - constant (32.44, when f in MHz and d in km, change to -27.55 when f in MHz and d in m)
• FSPL - Free Space Path Loss
• Ptx - transmitter power, dBm ( up to 20 dBm (100mW) )
• CLtx, CLrx - cable loss at transmitter and receiver, dB ( 0, if no cables )
• AGtx, AGrx - antenna gain at transmitter and receiver, dBi
• Prx - receiver sensitivity, dBm ( down to -100 dBm (0.1pW) )
• FM - fade margin, dB ( more than 14 dB (normal) or more than 22 dB (good))
• f - signal frequency, MHz
• d - distance, m or km (depends on value of K)

Note: there is an error in formulas from TP-Link support site (mising ^).

Substitute Prx with received signal strength to get a distance from WiFi AP.

Example: Ptx = 16 dBm, AGtx = 2 dBi, AGrx = 0, Prx = -51 dBm (received signal strength), CLtx = 0, CLrx = 0, f = 2442 MHz (7'th 802.11bgn channel), FM = 22. Result: FSPL = 47 dB, d = 2.1865 m

Note: FM (fade margin) seems to be irrelevant here, but I'm leaving it because of the original formula.

You should take into acount walls, table http://www.liveport.com/wifi-signal-attenuation may help.

Example: (previous data) + one wooden wall ( 5 dB, from the table ). Result: FSPL = FSPL - 5 dB = 44 dB, d = 1.548 m

Also please note, that antena gain dosn't add power - it describes the shape of radiation pattern (donut in case of omnidirectional antena, zeppelin in case of directional antenna, etc).

None of this takes into account signal reflections (don't have an idea how to do this). Probably noise is also missing. So this math may be good only for rough distance estimation.

With Swift 5, according to your needs, you may choose one of the four following Playground code examples in order to solve your problem.

#1. Using ClosedRange reversed() method

ClosedRange has a method called reversed(). reversed() method has the following declaration:

func reversed() -> ReversedCollection<ClosedRange<Bound>>

Returns a view presenting the elements of the collection in reverse order.

Usage:

let reversedCollection = (0 ... 5).reversed()

for index in reversedCollection {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

As an alternative, you can use Range reversed() method:

let reversedCollection = (0 ..< 6).reversed()

for index in reversedCollection {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#2. Using sequence(first:next:) function

Swift Standard Library provides a function called sequence(first:next:). sequence(first:next:) has the following declaration:

func sequence<T>(first: T, next: @escaping (T) -> T?) -> UnfoldFirstSequence<T>

Returns a sequence formed from first and repeated lazy applications of next.

Usage:

let unfoldSequence = sequence(first: 5, next: {
    $0 > 0 ? $0 - 1 : nil
})

for index in unfoldSequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#3. Using stride(from:through:by:) function

Swift Standard Library provides a function called stride(from:through:by:). stride(from:through:by:) has the following declaration:

func stride<T>(from start: T, through end: T, by stride: T.Stride) -> StrideThrough<T> where T : Strideable

Returns a sequence from a starting value toward, and possibly including, an end value, stepping by the specified amount.

Usage:

let sequence = stride(from: 5, through: 0, by: -1)

for index in sequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

As an alternative, you can use stride(from:to:by:):

let sequence = stride(from: 5, to: -1, by: -1)

for index in sequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#4. Using AnyIterator init(_:) initializer

AnyIterator has an initializer called init(_:). init(_:) has the following declaration:

init(_ body: @escaping () -> AnyIterator<Element>.Element?)

Creates an iterator that wraps the given closure in its next() method.

Usage:

var index = 5

guard index >= 0 else { fatalError("index must be positive or equal to zero") }

let iterator = AnyIterator({ () -> Int? in
    defer { index = index - 1 }
    return index >= 0 ? index : nil
})

for index in iterator {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

If needed, you can refactor the previous code by creating an extension method for Int and wrapping your iterator in it:

extension Int {

    func iterateDownTo(_ endIndex: Int) -> AnyIterator<Int> {
        var index = self
        guard index >= endIndex else { fatalError("self must be greater than or equal to endIndex") }

        let iterator = AnyIterator { () -> Int? in
            defer { index = index - 1 }
            return index >= endIndex ? index : nil
        }
        return iterator
    }

}

let iterator = 5.iterateDownTo(0)

for index in iterator {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

With no doctype tag, Chrome reports the same value for both calls.

Adding a strict doctype like <!DOCTYPE html> causes the values to work as advertised.

The doctype tag must be the very first thing in your document. E.g., you can't have any text before it, even if it doesn't render anything.

In addition to the answers above, you could use a small extension method:

public static class Extensions
{

and use it like so:

// open explorer window with given path
"Explorer".Run(path);   

// open a shell (remanins open)
"cmd".Run(path, "/K");

Use the following in a stored procedure:

IF NOT EXISTS( SELECT NULL
            FROM INFORMATION_SCHEMA.COLUMNS
           WHERE table_name = 'tablename'
             AND table_schema = 'db_name'
             AND column_name = 'columnname')  THEN

  ALTER TABLE `TableName` ADD `ColumnName` int(1) NOT NULL default '0';

END IF;

See my answer to Stack Overflow question Finish All previous activities.

What you need is to add the Intent.FLAG_CLEAR_TOP. This flag makes sure that all activities above the targeted activity in the stack are finished and that one is shown.

Another thing that you need is the SINGLE_TOP flag. With this one you prevent Android from creating a new activity if there is one already created in the stack.

Just be wary that if the activity was already created, the intent with these flags will be delivered in the method called onNewIntent(intent) (you need to overload it to handle it) in the target activity.

Then in onNewIntent you have a method called restart or something that will call finish() and launch a new intent toward itself, or have a repopulate() method that will set the new data. I prefer the second approach, it is less expensive and you can always extract the onCreate logic into a separate method that you can call for populate.

There is actually a much simpler solution. See https://gist.github.com/colindean/5213685/#comment-882885:

"please note that unless you specifically want scp for some reason, the easiest way to transfer files from the host to the VM is to just put them in the same directory as the Vagrantfile - that directory is automatically mounted under /vagrant in the VM so you can copy or use them directly from the VM."

Three steps to implement your function:

Step#1 You can specify a string, including the chars A-Z and 0-9.

Like.

 String candidateChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";

Step#2 Then if you would like to generate a random char from this candidate string. You can use

 candidateChars.charAt(random.nextInt(candidateChars.length()));

Step#3 At last, specify the length of random string to be generated (in your description, it is 17). Writer a for-loop and append the random chars generated in step#2 to StringBuilder object.

Based on this, here is an example public class RandomTest {

public static void main(String[] args) {

    System.out.println(generateRandomChars(
            "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890", 17));
}

/**
 * 
 * @param candidateChars
 *            the candidate chars
 * @param length
 *            the number of random chars to be generated
 * 
 * @return
 */
public static String generateRandomChars(String candidateChars, int length) {
    StringBuilder sb = new StringBuilder();
    Random random = new Random();
    for (int i = 0; i < length; i++) {
        sb.append(candidateChars.charAt(random.nextInt(candidateChars
                .length())));
    }

    return sb.toString();
}

}

Using MVVM Light Toolkit:

Assuming that there is an Exit command in view model:

ICommand _exitCommand;
public ICommand ExitCommand
{
    get
    {
        if (_exitCommand == null)
            _exitCommand = new RelayCommand<object>(call => OnExit());
        return _exitCommand;
    }
}

void OnExit()
{
     var msg = new NotificationMessageAction<object>(this, "ExitApplication", (o) =>{});
     Messenger.Default.Send(msg);
}

This is received in the view:

Messenger.Default.Register<NotificationMessageAction<object>>(this, (m) => if (m.Notification == "ExitApplication")
{
     Application.Current.Shutdown();
});

On the other hand, I handle Closing event in MainWindow, using the instance of ViewModel:

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{ 
    if (((ViewModel.MainViewModel)DataContext).CancelBeforeClose())
        e.Cancel = true;
}

CancelBeforeClose checks the current state of view model and returns true if closing should be stopped.

Hope it helps someone.

When using Monkey Script I noticed that DispatchPress(KEYCODE_BACK) is doing nothing which really suck. In many cases this is due to the fact that the Activity doesn't consume the Key event. The solution to this problem is to use a mix of monkey script and adb shell input command in a sequence.

1 Using monkey script gave some great timing control. Wait a certain amount of second for the activity and is a blocking adb call.
2 Finally sending adb shell input keyevent 4 will end the running APK.

EG

adb shell monkey -p com.my.application -v -v -v -f /sdcard/monkey_script.txt 1
adb shell input keyevent 4

The other answers are several years old (and do not work for Windows Phone 8.1) so I figured I'd drop in another option. I used this to parse an RSS response for a Windows Phone app:

XDocument xdoc = new XDocument();
xdoc = XDocument.Parse(xml_string);

Don't prematurely optimize. If you have no reason to believe there's a speed bottleneck caused by string concatenations then just stick with + and +=:

s  = 'foo'
s += 'bar'
s += 'baz'

That said, if you're aiming for something like Java's StringBuilder, the canonical Python idiom is to add items to a list and then use str.join to concatenate them all at the end:

l = []
l.append('foo')
l.append('bar')
l.append('baz')

s = ''.join(l)

There are two major options in matplotlib (pylab) to control the image size:

1. You can set the size of the resulting image in inches
2. You can define the DPI (dots per inch) for output file (basically, it is a resolution)

Normally, you would like to do both, because this way you will have full control over the resulting image size in pixels. For example, if you want to render exactly 800x600 image, you can use DPI=100, and set the size as 8 x 6 in inches:

import matplotlib.pyplot as plt
# plot whatever you need...
# now, before saving to file:
figure = plt.gcf() # get current figure
figure.set_size_inches(8, 6)
# when saving, specify the DPI
plt.savefig("myplot.png", dpi = 100)

One can use any DPI. In fact, you might want to play with various DPI and size values to get the result you like the most. Beware, however, that using very small DPI is not a good idea, because matplotlib may not find a good font to render legend and other text. For example, you cannot set the DPI=1, because there are no fonts with characters rendered with 1 pixel :)

From other comments I understood that other issue you have is proper text rendering. For this, you can also change the font size. For example, you may use 6 pixels per character, instead of 12 pixels per character used by default (effectively, making all text twice smaller).

import matplotlib
#...
matplotlib.rc('font', size=6)

Finally, some references to the original documentation: http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.savefig, http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.gcf, http://matplotlib.sourceforge.net/api/figure_api.html#matplotlib.figure.Figure.set_size_inches, http://matplotlib.sourceforge.net/users/customizing.html#dynamic-rc-settings

P.S. Sorry, I didn't use pylab, but as far as I'm aware, all the code above will work same way in pylab - just replace plt in my code with the pylab (or whatever name you assigned when importing pylab). Same for matplotlib - use pylab instead.

There is no way in PostgreSQL to deconstruct a scalar JSON object. Thus, as you point out,

select  length(to_json('Some "text"'::TEXT) ::TEXT);

is 15,

The trick is to convert the JSON into an array of one JSON element, then extract that element using ->>.

select length( array_to_json(array[to_json('Some "text"'::TEXT)])->>0 );

will return 11.
