we can simply copy the code from tostring of object class to get the reference of string

class Test
{
  public static void main(String args[])
  {
    String a="nikhil";     // it stores in String constant pool
    String s=new String("nikhil");    //with new stores in heap
    System.out.println(Integer.toHexString(System.identityHashCode(a)));
    System.out.println(Integer.toHexString(System.identityHashCode(s)));
  }
}

HashMap supports both null keys and values

http://docs.oracle.com/javase/6/docs/api/java/util/HashMap.html

... and permits null values and the null key

So your problem is probably not the map itself.

@about8 : there is a pretty serious bug there.

Zam obj1 = new Zam("foo", "bar", "baz");
Zam obj2 = new Zam("fo", "obar", "baz");

same hashcode

you probably want something like

public int hashCode() {
    return (getFoo().hashCode() + getBar().hashCode()).toString().hashCode();

(can you get hashCode directly from int in Java these days? I think it does some autocasting.. if that's the case, skip the toString, it's ugly.)

We have two problems to cope with.

1. You cannot provide a sensible GetHashCode() if any field in the object can be changed. Also often a object will NEVER be used in a collection that depends on GetHashCode(). So the cost of implementing GetHashCode() is often not worth it, or it is not possible.

2. If someone puts your object in a collection that calls GetHashCode() and you have overrided Equals() without also making GetHashCode() behave in a correct way, that person may spend days tracking down the problem.

Therefore by default I do.

public class Foo
{
    public int FooId { get; set; }
    public string FooName { get; set; }

    public override bool Equals(object obj)
    {
        Foo fooItem = obj as Foo;

        if (fooItem == null)
        {
           return false;
        }

        return fooItem.FooId == this.FooId;
    }

    public override int GetHashCode()
    {
        // Some comment to explain if there is a real problem with providing GetHashCode() 
        // or if I just don't see a need for it for the given class
        throw new Exception("Sorry I don't know what GetHashCode should do for this class");
    }
}

You can also use guava Table implementation for this.

Table represents a special map where two keys can be specified in combined fashion to refer to a single value. It is similar to creating a map of maps.

//create a table
  Table<String, String, String> employeeTable = HashBasedTable.create();

  //initialize the table with employee details
  employeeTable.put("IBM", "101","Mahesh");
  employeeTable.put("IBM", "102","Ramesh");
  employeeTable.put("IBM", "103","Suresh");

  employeeTable.put("Microsoft", "111","Sohan");
  employeeTable.put("Microsoft", "112","Mohan");
  employeeTable.put("Microsoft", "113","Rohan");

  employeeTable.put("TCS", "121","Ram");
  employeeTable.put("TCS", "122","Shyam");
  employeeTable.put("TCS", "123","Sunil");

  //get Map corresponding to IBM
  Map<String,String> ibmEmployees =  employeeTable.row("IBM");

Are you trying to test if two objects are the equal? ie: their properties are equal?

If this is the case, you'll probably have noticed this situation:

var a = { foo : "bar" };
var b = { foo : "bar" };
alert (a == b ? "Equal" : "Not equal");
// "Not equal"

you might have to do something like this:

function objectEquals(obj1, obj2) {
    for (var i in obj1) {
        if (obj1.hasOwnProperty(i)) {
            if (!obj2.hasOwnProperty(i)) return false;
            if (obj1[i] != obj2[i]) return false;
        }
    }
    for (var i in obj2) {
        if (obj2.hasOwnProperty(i)) {
            if (!obj1.hasOwnProperty(i)) return false;
            if (obj1[i] != obj2[i]) return false;
        }
    }
    return true;
}

Obviously that function could do with quite a bit of optimisation, and the ability to do deep checking (to handle nested objects: var a = { foo : { fu : "bar" } }) but you get the idea.

As FOR pointed out, you might have to adapt this for your own purposes, eg: different classes may have different definitions of "equal". If you're just working with plain objects, the above may suffice, otherwise a custom MyClass.equals() function may be the way to go.

hashCode

Whenever you override equals(), you are also expected to override hashCode(). The hash code is used when storing the object as a key in a map.

A hash code is a number that puts instances of a class into a finite number of categories. Imagine that I gave you a deck of cards, and I told you that I was going to ask you for specific cards and I want to get the right card back quickly. You have as long as you want to prepare, but I’m in a big hurry when I start asking for cards. You might make 13 piles of cards: All of the aces in one pile, all the twos in another pile, and so forth. That way, when I ask for the five of hearts, you can just pull the right card out of the four cards in the pile with fives. It is certainly faster than going through the whole deck of 52 cards! You could even make 52 piles if you had enough space on the table.

If you actually want the answer back as a string as opposed to a byte array, you could always do something like this:

String plaintext = "your text here";
MessageDigest m = MessageDigest.getInstance("MD5");
m.reset();
m.update(plaintext.getBytes());
byte[] digest = m.digest();
BigInteger bigInt = new BigInteger(1,digest);
String hashtext = bigInt.toString(16);
// Now we need to zero pad it if you actually want the full 32 chars.
while(hashtext.length() < 32 ){
  hashtext = "0"+hashtext;
}

If you override equals() and not hashcode(), you will not find any problem unless you or someone else uses that class type in a hashed collection like HashSet. People before me have clearly explained the documented theory multiple times, I am just here to provide a very simple example.

Consider a class whose equals() need to mean something customized :-

    public class Rishav {

        private String rshv;

        public Rishav(String rshv) {
            this.rshv = rshv;
        }

        /**
        * @return the rshv
        */
        public String getRshv() {
            return rshv;
        }

        /**
        * @param rshv the rshv to set
        */
        public void setRshv(String rshv) {
            this.rshv = rshv;
        }

        @Override
        public boolean equals(Object obj) {
            if (obj instanceof Rishav) {
                obj = (Rishav) obj;
                if (this.rshv.equals(((Rishav) obj).getRshv())) {
                    return true;
                } else {
                    return false;
                }
            } else {
                return false;
            }
        }

        @Override
        public int hashCode() {
            return rshv.hashCode();
        }

    }

Now consider this main class :-

    import java.util.HashSet;
    import java.util.Set;

    public class TestRishav {

        public static void main(String[] args) {
            Rishav rA = new Rishav("rishav");
            Rishav rB = new Rishav("rishav");
            System.out.println(rA.equals(rB));
            System.out.println("-----------------------------------");

            Set<Rishav> hashed = new HashSet<>();
            hashed.add(rA);
            System.out.println(hashed.contains(rB));
            System.out.println("-----------------------------------");

            hashed.add(rB);
            System.out.println(hashed.size());
        }

    }

This will yield the following output :-

    true
    -----------------------------------
    true
    -----------------------------------
    1

I am happy with the results. But if I have not overridden hashCode(), it will cause nightmare as objects of Rishav with same member content will no longer be treated as unique as the hashCode will be different, as generated by default behavior, here's the would be output :-

    true
    -----------------------------------
    false
    -----------------------------------

What you are getting is the result of the toString() method of the Object class or, more precisely, the identityHashCode() as uzay95 has pointed out.

"When we create an object in java with new keyword, we are getting a memory address from the OS."

It is important to realize that everything you do in Java is handled by the Java Virtual Machine. It is the JVM that is giving this information. What actually happens in the RAM of the host operating system depends entirely on the implementation of the JRE.

Fastest way is this :

    public static string GetHash(string input)
    {
        return string.Join("", (new SHA1Managed().ComputeHash(Encoding.UTF8.GetBytes(input))).Select(x => x.ToString("X2")).ToArray());
    }

For Small character output use x2 in replace of of X2

As it is said, a picture is worth 1000 words. I say: some code is better than 1000 words. Here's the source code of HashMap. Get method:

/**
     * Implements Map.get and related methods
     *
     * @param hash hash for key
     * @param key the key
     * @return the node, or null if none
     */
    final Node<K,V> getNode(int hash, Object key) {
        Node<K,V>[] tab; Node<K,V> first, e; int n; K k;
        if ((tab = table) != null && (n = tab.length) > 0 &&
            (first = tab[(n - 1) & hash]) != null) {
            if (first.hash == hash && // always check first node
                ((k = first.key) == key || (key != null && key.equals(k))))
                return first;
            if ((e = first.next) != null) {
                if (first instanceof TreeNode)
                    return ((TreeNode<K,V>)first).getTreeNode(hash, key);
                do {
                    if (e.hash == hash &&
                        ((k = e.key) == key || (key != null && key.equals(k))))
                        return e;
                } while ((e = e.next) != null);
            }
        }
        return null;
    }

So it becomes clear that hash is used to find the "bucket" and the first element is always checked in that bucket. If not, then equals of the key is used to find the actual element in the linked list.

Let's see the put() method:

  /**
     * Implements Map.put and related methods
     *
     * @param hash hash for key
     * @param key the key
     * @param value the value to put
     * @param onlyIfAbsent if true, don't change existing value
     * @param evict if false, the table is in creation mode.
     * @return previous value, or null if none
     */
    final V putVal(int hash, K key, V value, boolean onlyIfAbsent,
                   boolean evict) {
        Node<K,V>[] tab; Node<K,V> p; int n, i;
        if ((tab = table) == null || (n = tab.length) == 0)
            n = (tab = resize()).length;
        if ((p = tab[i = (n - 1) & hash]) == null)
            tab[i] = newNode(hash, key, value, null);
        else {
            Node<K,V> e; K k;
            if (p.hash == hash &&
                ((k = p.key) == key || (key != null && key.equals(k))))
                e = p;
            else if (p instanceof TreeNode)
                e = ((TreeNode<K,V>)p).putTreeVal(this, tab, hash, key, value);
            else {
                for (int binCount = 0; ; ++binCount) {
                    if ((e = p.next) == null) {
                        p.next = newNode(hash, key, value, null);
                        if (binCount >= TREEIFY_THRESHOLD - 1) // -1 for 1st
                            treeifyBin(tab, hash);
                        break;
                    }
                    if (e.hash == hash &&
                        ((k = e.key) == key || (key != null && key.equals(k))))
                        break;
                    p = e;
                }
            }
            if (e != null) { // existing mapping for key
                V oldValue = e.value;
                if (!onlyIfAbsent || oldValue == null)
                    e.value = value;
                afterNodeAccess(e);
                return oldValue;
            }
        }
        ++modCount;
        if (++size > threshold)
            resize();
        afterNodeInsertion(evict);
        return null;
    }

It's slightly more complicated, but it becomes clear that the new element is put in the tab at the position calculated based on hash:

i = (n - 1) & hash here i is the index where the new element will be put (or it is the "bucket"). n is the size of the tab array (array of "buckets").

First, it is tried to be put as the first element of in that "bucket". If there is already an element, then append a new node to the list.

It's not unique to WP7--it's present on all .Net objects. It sort of does what you describe, but I would not recommend it as a unique identifier in your apps, as it is not guaranteed to be unique.

Object.GetHashCode Method

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!

As said above, in general you should not rely on the hash code of a class remaining the same. Note that even subsequent runs of the same application on the same VM may produce different hash values. AFAIK the Sun JVM's hash function calculates the same hash on every run, but that's not guaranteed.

Note that this is not theoretical. The hash function for java.lang.String was changed in JDK1.2 (the old hash had problems with hierarchical strings like URLs or file names, as it tended to produce the same hash for strings which only differed at the end).

java.lang.String is a special case, as the algorithm of its hashCode() is (now) documented, so you can probably rely on that. I'd still consider it bad practice. If you need a hash algorithm with special, documented properties, just write one :-).

Here is my simplistic approach. I am using the classic builder pattern for this. It is typesafe (no boxing/unboxing) and also compatbile with .NET 2.0 (no extension methods etc.).

It is used like this:

public override int GetHashCode()
{
    HashBuilder b = new HashBuilder();
    b.AddItems(this.member1, this.member2, this.member3);
    return b.Result;
} 

And here is the acutal builder class:

internal class HashBuilder
{
    private const int Prime1 = 17;
    private const int Prime2 = 23;
    private int result = Prime1;

    public HashBuilder()
    {
    }

    public HashBuilder(int startHash)
    {
        this.result = startHash;
    }

    public int Result
    {
        get
        {
            return this.result;
        }
    }

    public void AddItem<T>(T item)
    {
        unchecked
        {
            this.result = this.result * Prime2 + item.GetHashCode();
        }
    }

    public void AddItems<T1, T2>(T1 item1, T2 item2)
    {
        this.AddItem(item1);
        this.AddItem(item2);
    }

    public void AddItems<T1, T2, T3>(T1 item1, T2 item2, T3 item3)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
    }

    public void AddItems<T1, T2, T3, T4>(T1 item1, T2 item2, T3 item3, 
        T4 item4)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
        this.AddItem(item4);
    }

    public void AddItems<T1, T2, T3, T4, T5>(T1 item1, T2 item2, T3 item3, 
        T4 item4, T5 item5)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
        this.AddItem(item4);
        this.AddItem(item5);
    }        

    public void AddItems<T>(params T[] items)
    {
        foreach (T item in items)
        {
            this.AddItem(item);
        }
    }
}

I think your questions will all be answered if you understand how Sets, and in particular HashSets work. A set is a collection of unique objects, with Java defining uniqueness in that it doesn't equal anything else (equals returns false).

The HashSet takes advantage of hashcodes to speed things up. It assumes that two objects that equal eachother will have the same hash code. However it does not assume that two objects with the same hash code mean they are equal. This is why when it detects a colliding hash code, it only compares with other objects (in your case one) in the set with the same hash code.

Just to augment the other answers from a different angle.

If you want to reuse hashcode(s) from 'above' and derive new ones using your class' immutatable state, then a call to super will work. While this may/may not cascade all the way up to Object (i.e. some ancestor may not call super), it will allow you to derive hashcodes by reuse.

@Override
public int hashCode() {
    int ancestorHash = super.hashCode();
    // now derive new hash from ancestorHash plus immutable instance vars (id fields)
}

here's a link that explains many different hash functions, for now I prefer the ELF hash function for your particular problem. It takes as input a string of arbitrary length.

Just use hidden secret property with the defineProperty enumerable: false

It work very fast:

• The first read uniqueId: 1,257,500 ops/s
• All others: 309,226,485 ops/s

var nextObjectId = 1
function getNextObjectId() {
    return nextObjectId++
}

var UNIQUE_ID_PROPERTY_NAME = '458d576952bc489ab45e98ac7f296fd9'
function getObjectUniqueId(object) {
    if (object == null) {
        return null
    }

    var id = object[UNIQUE_ID_PROPERTY_NAME]

    if (id != null) {
        return id
    }

    if (Object.isFrozen(object)) {
        return null
    }

    var uniqueId = getNextObjectId()
    Object.defineProperty(object, UNIQUE_ID_PROPERTY_NAME, {
        enumerable: false,
        configurable: false,
        writable: false,
        value: uniqueId,
    })

    return uniqueId
}

I know that this has been answered, but it's at least useful to note that you can use:

http://msdn.microsoft.com/en-us/library/system.object.referenceequals.aspx

Which will not give you a "unique id" directly, but combined with WeakReferences (and a hashset?) could give you a pretty easy way of tracking various instances.

Created a directive (ng-repeat with lazy loading) 

which loads data when it reaches to bottom of the page and remove half of the previously loaded data and when it reaches to top of the div again previous data(depending upon on page number) will be loaded removing half of the current data So on DOM at a time only limited data is present which may leads to better performance instead of rendering whole data on load.

Another Solution: If you using UI-grid in the project then  same implementation is there in UI grid with infinite-scroll.

Depending upon height of the division it loads the data and upon scroll new data will be append and previous data will be removed.

According to this discussion, Promise has finally been called CompletableFuture for inclusion in Java 8, and its javadoc explains:

A Future that may be explicitly completed (setting its value and status), and may be used as a CompletionStage, supporting dependent functions and actions that trigger upon its completion.

An example is also given on the list:

f.then((s -> aStringFunction(s)).thenAsync(s -> ...);

Note that the final API is slightly different but allows similar asynchronous execution:

CompletableFuture<String> f = ...;
f.thenApply(this::modifyString).thenAccept(System.out::println);

if the string is mutable, then you can transform it in place using this form:

[string replaceOccurrencesOfString:@" "
                        withString:@""
                           options:0
                             range:NSMakeRange(0, string.length)];

this is also useful if you would like the result to be a mutable instance of an input string:

NSMutableString * string = [concreteString mutableCopy];
[string replaceOccurrencesOfString:@" "
                        withString:@""
                           options:0
                             range:NSMakeRange(0, string.length)];

If you have multiple ports to allow in Centos 7 FIrewalld then we can use the following command.

#firewall-cmd --add-port={port number/tcp,port number/tcp} --permanent

#firewall-cmd --reload


And check the Port opened or not after reloading the firewall.


#firewall-cmd --list-port

From Docker docs: https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/#add-or-copy

"Although ADD and COPY are functionally similar, generally speaking, COPY is preferred. That’s because it’s more transparent than ADD. COPY only supports the basic copying of local files into the container, while ADD has some features (like local-only tar extraction and remote URL support) that are not immediately obvious. Consequently, the best use for ADD is local tar file auto-extraction into the image, as in ADD rootfs.tar.xz /.

If you have multiple Dockerfile steps that use different files from your context, COPY them individually, rather than all at once. This will ensure that each step’s build cache is only invalidated (forcing the step to be re-run) if the specifically required files change.

For example:

 COPY requirements.txt /tmp/
 RUN pip install --requirement /tmp/requirements.txt
 COPY . /tmp/

Results in fewer cache invalidations for the RUN step, than if you put the COPY . /tmp/ before it.

Because image size matters, using ADD to fetch packages from remote URLs is strongly discouraged; you should use curl or wget instead. That way you can delete the files you no longer need after they’ve been extracted and you won’t have to add another layer in your image. For example, you should avoid doing things like:

 ADD http://example.com/big.tar.xz /usr/src/things/
 RUN tar -xJf /usr/src/things/big.tar.xz -C /usr/src/things
 RUN make -C /usr/src/things all

And instead, do something like:

 RUN mkdir -p /usr/src/things \
     && curl -SL htt,p://example.com/big.tar.xz \
     | tar -xJC /usr/src/things \
     && make -C /usr/src/things all

For other items (files, directories) that do not require ADD’s tar auto-extraction capability, you should always use COPY."

Apache commons collections 4 has a CircularFifoQueue<> which is what you are looking for. Quoting the javadoc:

CircularFifoQueue is a first-in first-out queue with a fixed size that replaces its oldest element if full.

    import java.util.Queue;
    import org.apache.commons.collections4.queue.CircularFifoQueue;

    Queue<Integer> fifo = new CircularFifoQueue<Integer>(2);
    fifo.add(1);
    fifo.add(2);
    fifo.add(3);
    System.out.println(fifo);

    // Observe the result: 
    // [2, 3]

If you are using an older version of the Apache commons collections (3.x), you can use the CircularFifoBuffer which is basically the same thing without generics.

Update: updated answer following release of commons collections version 4 that supports generics.

"Note that the hard-float and soft-float ABIs are not link-compatible; you must compile your entire program with the same ABI, and link with a compatible set of libraries." https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html arm-none-eabi-gcc.exe

Silicon Labs "kjostera" "Employee" response to EFR32 Flex Gecko (crossreference Cortex-M4F): "So code compiled with the softfp ABI is not link time compatible with code compiled with hardfp ABI. So since we currently only support RAIL library compiled using the softfp ABI, this means that you will have to build your application as well using the softfp ABI." "Note that using softfp ABI does not mean that your code cannot use FPU instructions. Any code doing floating point arithmetic will use the FPU when the compiler thinks that it makes sense." "kjostera" then goes on to demonstrate that the GCC 7 generated Assembly for both the case of -mfloat-abi=softfp and -mfloat-abi=hard, the vmul.f32 instruction is invoked and the instruction count is 10 for softfp and 9 for hard. https://www.silabs.com/community/mcu/32-bit/forum.topic.html/enable_fpu_in_rail-p-SEYr https://www.silabs.com/documents/public/data-sheets/efr32fg1-datasheet.pdf https://www.silabs.com/documents/public/reference-manuals/efr32xg12-rm.pdf https://www.silabs.com/documents/public/reference-manuals/efr32xg13-rm.pdf https://www.silabs.com/documents/public/reference-manuals/efr32xg14-rm.pdf

You can also use kafkactl for this:

# get all consumer groups (output as yaml)
kafkactl get consumer-groups -o yaml

# get only consumer groups assigned to a single topic (output as table)
kafkactl get consumer-groups --topic topic-a

Sample output (e.g. as yaml):

name: my-group
protocoltype: consumer
topics:
 - topic-a
 - topic-b
 - topic-c

Most easy way..

//div[@class="Test"]

Assuming you want to find <div class="Test"> as described.

Try the following:

$.ajax({
  url: _saveDeviceUrl
, type: 'POST'
, contentType: 'application/json'
, dataType: 'json'
, data: {'myArray': postData}
, success: _madeSave.bind(this)
//, processData: false //Doesn't help
});

I found out that inflating the header view as:

inflater.inflate(R.layout.listheader, container, false);

being container the Fragment's ViewGroup, inflates the headerview with a LayoutParam that extends from FragmentLayout but ListView expect it to be a AbsListView.LayoutParams instead.

So, my problem was solved solved by inflating the header view passing the list as container:

ListView list = fragmentview.findViewById(R.id.listview);
View headerView = inflater.inflate(R.layout.listheader, list, false);

then

list.addHeaderView(headerView, null, false);

Kinda late answer but I hope this can help someone

Say that authorsToRemove is an IEnumerable<T> that contains the elements you want to remove from authorsList.

Then here is another very simple way to accomplish the removal task asked by the OP:

authorsList.RemoveAll(authorsToRemove.Contains);

For me it work fine

&:not(:last-child){
            text-transform: uppercase;
        }

tl;dr

To keep Map< Integer , String > in an order sorted by key, use either of the two classes implementing the SortedMap/NavigableMap interfaces:

• TreeMap
• ConcurrentSkipListMap

If manipulating the map within a single thread, use the first, TreeMap. If manipulating across threads, use the second, ConcurrentSkipListMap.

For details, see the table below and the following discussion.

Details

Here is a graphic table I made showing the features of the ten Map implementations bundled with Java 11.

The NavigableMap interface is what SortedMap should have been in the first place. The SortedMap logically should be removed but cannot be as some 3rd-party map implementations may be using interface.

As you can see in this table, only two classes implement the SortedMap/NavigableMap interfaces:

• TreeMap
• ConcurrentSkipListMap

Both of these keep keys in sorted order, either by their natural order (using compareTo method of the Comparable(https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Comparable.html) interface) or by a Comparator implementation you pass. The difference between these two classes is that the second one, ConcurrentSkipListMap, is thread-safe, highly concurrent.

See also the Iteration order column in the table below.

• The LinkedHashMap class returns its entries by the order in which they were originally inserted.
• EnumMap returns entries in the order by which the enum class of the key is defined. For example, a map of which employee is covering which day of the week (Map< DayOfWeek , Person >) uses the DayOfWeek enum class built into Java. That enum is defined with Monday first and Sunday last. So entries in an iterator will appear in that order.

The other six implementations make no promise about the order in which they report their entries.

Throughout my researches, I've found 2 viable solutions.

1. If you're using any type of connections, ssh, samba, mounting, disconnect/unmount and reconnect/remount. Try again, this often resolved the problem for me. After that you can do svn cleanup or just keep on working normally (depending on when the problem appeared). Rebooting my computer also fixed the problem once... yes it's dumb I know!

2. Some times all there is to do is to rm -rf your files (or if you're not familiar with the term, just delete your svn folder), and recheckout your svn repository once again. Please note that this does not always solve the problem and you might also have changes you don't want to lose. Which is why I use it as the second option.

Hope this helps you guys!

The most recent version of git scm (testet 2.11.1) allows to enable symbolic links. But you have to clone the repository with the symlinks again git clone -c core.symlinks=true <URL>. You need to run this command with administrator rights. It is also possible to create symlinks on Windows with mklink. Check out the wiki.

here the writer suggests this:

public boolean isOnline() {
    Runtime runtime = Runtime.getRuntime();
    try {
        Process ipProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
        int     exitValue = ipProcess.waitFor();
        return (exitValue == 0);
    } catch (IOException | InterruptedException e) { e.printStackTrace(); }
    return false;
}

Possible Questions

• Is this really fast enough?Yes, very fast!
• Couldn’t I just ping my own page, which I want to request anyways? Sure! You could even check both, if you want to differentiate between “internet connection available” and your own servers beeing reachable What if the DNS is down? Google DNS (e.g. 8.8.8.8) is the largest public DNS service in the world. As of 2013 it serves 130 billion requests a day. Let ‘s just say, your app not responding would probably not be the talk of the day.

read the link. its seems very good

EDIT: in my exp of using it, it's not as fast as this method:

public boolean isOnline() {
    NetworkInfo netInfo = connectivityManager.getActiveNetworkInfo();
    return netInfo != null && netInfo.isConnectedOrConnecting();
}

they are a bit different but in the functionality for just checking the connection to internet the first method may become slow due to the connection variables.

• For HTML5, <input type="text" disabled /> is valid and used by W3C on their samples.
• In fact, both ways works on all major browsers.

In a nutshell:

An imperative language specfies a series of instructions that the computer executes in sequence (do this, then do that).

A declarative language declares a set of rules about what outputs should result from which inputs (eg. if you have A, then the result is B). An engine will apply these rules to inputs, and give an output.

A functional language declares a set of mathematical/logical functions which define how input is translated to output. eg. f(y) = y * y. it is a type of declarative language.

Assuming that you have access to Prototype, this could work. I wrote this code for myself just a few minutes ago; I only needed a single key at a time, so this isn't time efficient for big lists of key:value pairs or for spitting out multiple key names.

function key(int) {
    var j = -1;
    for(var i in this) {
        j++;
        if(j==int) {
            return i;
        } else {
            continue;
        }
    }
}
Object.prototype.key = key;

This is numbered to work the same way that arrays do, to save headaches. In the case of your code:

buttons.key(0) // Should result in "button1"

I used Ctrl + F5 keyboard combination. By doing so, instead of reading from cache, I wanted to get a new response. The solution is to do hard refresh the page.

"The HTTP 304 Not Modified client redirection response code indicates that there is no need to retransmit the requested resources. It is an implicit redirection to a cached resource."

My problem was an invalid Authorization token after 5 minutes. The push took more than 5 minutes because of the image size.

I've fixed it by increasing the "Authorization token duration" to 10 minutes.

Assignment in bash scripts cannot have spaces around the = and you probably want your date commands enclosed in backticks $():

#!/bin/bash
folder="ABC"
useracct='test'
day=$(date "+%d")
month=$(date "+%B")
year=$(date "+%Y")
folderToBeMoved="/users/$useracct/Documents/Archive/Primetime.eyetv"
newfoldername="/Volumes/Media/Network/$folder/$month$day$year"
ECHO "Network is $network" $network
ECHO "day is $day"
ECHO "Month is $month"
ECHO "YEAR is $year"
ECHO "source is $folderToBeMoved"
ECHO "dest is $newfoldername"
mkdir $newfoldername
cp -R $folderToBeMoved $newfoldername
if [-f $newfoldername/Primetime.eyetv]; then rm $folderToBeMoved; fi

With the last three lines commented out, for me this outputs:

dest is /Volumes/Media/Network/ABC/March162010

Set DHOME variable

For anyone wondering about the difference between -1.#IND00 and -1.#IND (which the question specifically asked, and none of the answers address):

-1.#IND00

This specifically means a non-zero number divided by zero, e.g. 3.14 / 0 (source)

-1.#IND (a synonym for NaN)

This means one of four things (see wiki from source):

1) sqrt or log of a negative number

2) operations where both variables are 0 or infinity, e.g. 0 / 0

3) operations where at least one variable is already NaN, e.g. NaN * 5

4) out of range trig, e.g. arcsin(2)

Here's how you can check the contents of the EntityValidationErrors in Visual Studio (without writing any extra code) i.e. during Debugging in the IDE.

The Problem?

You are right, the Visual Studio debugger's View Details Popup doesn't show the actual errors inside the EntityValidationErrors collection .

The Solution!

Just add the following expression in a Quick Watch window and click Reevaluate.

((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors

In my case, see how I am able to expand into the ValidationErrors List inside the EntityValidationErrors collection

Using this in combination with Laravel solved my problem. Just add this header to your jquery request Access-Control-Request-Headers: x-requested-with and make sure that your server side response has this header set Access-Control-Allow-Headers: *.

It says

In all browsers, the load, scroll, and error events (e.g., on an <img> element) do not bubble. In Internet Explorer 8 and lower, the paste and reset events do not bubble. Such events are not supported for use with delegation, but they can be used when the event handler is directly attached to the element generating the event.

If you want to do something when a new input box is added then you can simply write the code after appending it.

$('#add').click(function(){
        $('body').append(x);
        // Your code can be here
    });

And if you want the same code execute when the first input box within the document is loaded then you can write a function and call it in both places i.e. $('#add').click and document's ready event

Maybe you can try this: though please note - This pulls the column count, not the row count

 using (SqlDataReader reader = command.ExecuteReader())
 {
     while (reader.Read())
     {
         int count = reader.VisibleFieldCount;
         Console.WriteLine(count);
     }
 }

Tell the option element to be 13pt

select option{
    font-size: 13pt;
}

and then the first option element to be 7pt

select option:first-child {
    font-size: 7pt;
}

You have an error in your OrderQuantity column. It is named "OrderQuantity" in the INSERT statement and "OrderQantity" in the table definition.

Also, I don't think you can use NOW() as default value in OrderDate. Try to use the following:

 OrderDate TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

This is one way to do it:

SQL> set serveroutput on
SQL> CREATE OR REPLACE TYPE MyType AS VARRAY(200) OF VARCHAR2(50);
  2  /

  2  BEGIN
  3    FOR i IN 1..t_in.count LOOP
  4      dbms_output.put_line(t_in(i));
  5    END LOOP;

  7  /

Procedure created

SQL> DECLARE
  2    v_t MyType;

  4    v_t := MyType();
  5    v_t.EXTEND(10);

  7    v_t(2) := 'A second test line';
  8    testing(v_t);
  9  END;
 10  /

this is a test
A second test line

To expand on my comment to @dcp's answer, here's how you could implement the solution proposed there if you wanted to use an associative array:

SQL> CREATE OR REPLACE PACKAGE p IS
  2    TYPE p_type IS TABLE OF VARCHAR2(50) INDEX BY BINARY_INTEGER;
  3  
  4    PROCEDURE pp (inp p_type);
  5  END p;
  6  /

Package created
SQL> CREATE OR REPLACE PACKAGE BODY p IS
  2    PROCEDURE pp (inp p_type) IS
  3    BEGIN
  4      FOR i IN 1..inp.count LOOP
  5        dbms_output.put_line(inp(i));
  6      END LOOP;
  7    END pp;
  8  END p;
  9  /

Package body created
SQL> DECLARE
  2    v_t p.p_type;
  3  BEGIN
  4    v_t(1) := 'this is a test of p';
  5    v_t(2) := 'A second test line for p';
  6    p.pp(v_t);
  7  END;
  8  /

this is a test of p
A second test line for p

This trades creating a standalone Oracle TYPE (which cannot be an associative array) with requiring the definition of a package that can be seen by all in order that the TYPE it defines there can be used by all.

Give the form an id, and then:

document.getElementById("yourFormId").submit();

Best practice would probably be to give your link an id too, and get rid of the event handler:

document.getElementById("yourLinkId").onclick = function() {
    document.getElementById("yourFormId").submit();
}

Besides all above solutions, check if you have the "id" or any custom defined parameter in the DELETE method is matching the route config.

public void Delete(int id)
{
    //some code here
}

If you hit with repeated 405 errors better reset the method signature to default as above and try.

The route config by default will look for id in the URL. So the parameter name id is important here unless you change the route config under the App_Start folder.

You may change the data type of the id though.

For example the method below should work just fine:

public void Delete(string id)
{
    //some code here
}

Note: Also ensure that you pass the data over the url not the data method that will carry the payload as body content.

DELETE http://{url}/{action}/{id}

Example:

DELETE http://localhost/item/1

Hope it helps.

As always in python, there are of course several ways to do it, but there is one obvious way to do it.

tmpdict["ONE"]["TWO"]["THREE"] is the obvious way to do it.

When that does not fit well with your algorithm, that may be a hint that your structure is not the best for the problem.

If you just want to just save you repetative typing, you can of course alias a subset of the dict:

>>> two_dict = tmpdict['ONE']['TWO'] # now you can just write two_dict for tmpdict['ONE']['TWO']
>>> two_dict["spam"] = 23
>>> tmpdict
{'ONE': {'TWO': {'THREE': 10, 'spam': 23}}}

<input style="font-size:25px;" type="text"/>

The above code changes the font size to 25 pixels.

Suppose you have

boolean active;

Accessors method would be

public boolean isActive(){return this.active;}

public void setActive(boolean active){this.active = active;}

Why not use a Pivot?

Sample Table Filter Pivot

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

Solution:

sort -k 2 -n filename

more verbosely written as:

sort --key 2 --numeric-sort filename

Example:

$ cat filename
A 12
B 48
C 3

$ sort --key 2 --numeric-sort filename 
C 3
A 12
B 48

Explanation:

• -k # - this argument specifies the first column that will be used to sort. (note that column here is defined as a whitespace delimited field; the argument -k5 will sort starting with the fifth field in each line, not the fifth character in each line)

• -n - this option specifies a "numeric sort" meaning that column should be interpreted as a row of numbers, instead of text.

More:

Other common options include:

• -r - this option reverses the sorting order. It can also be written as --reverse.
• -i - This option ignores non-printable characters. It can also be written as --ignore-nonprinting.
• -b - This option ignores leading blank spaces, which is handy as white spaces are used to determine the number of rows. It can also be written as --ignore-leading-blanks.
• -f - This option ignores letter case. "A"=="a". It can also be written as --ignore-case.
• -t [new separator] - This option makes the preprocessing use a operator other than space. It can also be written as --field-separator.

There are other options, but these are the most common and helpful ones, that I use often.

To be able to access the form in your controller, you have to add it to a dummy scope object.

Something like $scope.dummy = {}

For your situation this would mean something like:

<form name="dummy.customerForm">

In your controller you will be able to access the form by:

$scope.dummy.customerForm

and you will be able to do stuff like

$scope.dummy.customerForm.$setPristine()

Having a '.' in your models will ensure that prototypal inheritance is in play. So, use <input type="text" ng-model="someObj.prop1"> rather than <input type="text" ng-model="prop1">

If you really want/need to use a primitive, there are two workarounds:

1.Use $parent.parentScopeProperty in the child scope. This will prevent the child scope from creating its own property. 2.Define a function on the parent scope, and call it from the child, passing the primitive value up to the parent (not always possible)

You had better use find_library command instead of link_directories. Concretely speaking there are two ways:

1. designate the path within the command

   find_library(NAMES gtest PATHS path1 path2 ... pathN)

2. set the variable CMAKE_LIBRARY_PATH

   set(CMAKE_LIBRARY_PATH path1 path2)
   find_library(NAMES gtest)

the reason is as flowings:

Note This command is rarely necessary and should be avoided where there are other choices. Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. The find_library() command provides the full path, which can generally be used directly in calls to target_link_libraries(). Situations where a library search path may be needed include: Project generators like Xcode where the user can switch target architecture at build time, but a full path to a library cannot be used because it only provides one architecture (i.e. it is not a universal binary).

Libraries may themselves have other private library dependencies that expect to be found via RPATH mechanisms, but some linkers are not able to fully decode those paths (e.g. due to the presence of things like $ORIGIN).

If a library search path must be provided, prefer to localize the effect where possible by using the target_link_directories() command rather than link_directories(). The target-specific command can also control how the search directories propagate to other dependent targets.

Steps to follow:-

1. Open Visual Studio code application & type Command+Shift+P and type command 'install code'. Then enter it.
2. You will see below message in Visual Studio Application :- shell command ' code' successfully installed in PATH.
3. Now, Jump to iTerm CLI and type code .
4. Then you will be able to redirect to Visual studio for any code change/view.

Hope this steps will be helpful for you.

If the effect you want is to center in the center of the screen no matter where you've scrolled to, it's even simpler than that:

In your CSS use (for example)

div.centered{
  width: 100px;
  height: 50px;
  position:fixed; 
  top: calc(50% - 25px); // half of width
  left: calc(50% - 50px); // half of height
}

No JS required.

json.dumps() is much more than just making a string out of a Python object, it would always produce a valid JSON string (assuming everything inside the object is serializable) following the Type Conversion Table.

For instance, if one of the values is None, the str() would produce an invalid JSON which cannot be loaded:

>>> data = {'jsonKey': None}
>>> str(data)
"{'jsonKey': None}"
>>> json.loads(str(data))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)

But the dumps() would convert None into null making a valid JSON string that can be loaded:

>>> import json
>>> data = {'jsonKey': None}
>>> json.dumps(data)
'{"jsonKey": null}'
>>> json.loads(json.dumps(data))
{u'jsonKey': None}

Yes, Java SE is where to start. All the tasks you mention can be handled with it.

There is a little known feature in TypeScript that allows you to use Mixins to create re-usable small objects. You can compose these into larger objects using multiple inheritance (multiple inheritance is not allowed for classes, but it is allowed for mixins - which are like interfaces with an associated implenentation).

More information on TypeScript Mixins

I think you could use this technique to share common components between many classes in your game and to re-use many of these components from a single class in your game:

Here is a quick Mixins demo... first, the flavours that you want to mix:

class CanEat {
    public eat() {
        alert('Munch Munch.');
    }
}

class CanSleep {
    sleep() {
        alert('Zzzzzzz.');
    }
}

Then the magic method for Mixin creation (you only need this once somewhere in your program...)

function applyMixins(derivedCtor: any, baseCtors: any[]) {
    baseCtors.forEach(baseCtor => {
        Object.getOwnPropertyNames(baseCtor.prototype).forEach(name => {
             if (name !== 'constructor') {
                derivedCtor.prototype[name] = baseCtor.prototype[name];
            }
        });
    }); 
}

And then you can create classes with multiple inheritance from mixin flavours:

class Being implements CanEat, CanSleep {
        eat: () => void;
        sleep: () => void;
}
applyMixins (Being, [CanEat, CanSleep]);

Note that there is no actual implementation in this class - just enough to make it pass the requirements of the "interfaces". But when we use this class - it all works.

var being = new Being();

// Zzzzzzz...
being.sleep();

You have to actively choose to install MSYS to get the make.exe. So you should always have at least (the native) mingw32-make.exe if MinGW was installed properly. And if you installed MSYS you will have make.exe (in the MSYS subfolder probably).

Note that many projects require first creating a makefile (e.g. using a configure script or automake .am file) and it is this step that requires MSYS or cygwin. Makes you wonder why they bothered to distribute the native make at all.

Once you have the makefile, it is unclear if the native executable requires a different path separator than the MSYS make (forward slashes vs backward slashes). Any autogenerated makefile is likely to have unix-style paths, assuming the native make can handle those, the compiled output should be the same.

Two major differences between apply and transform

There are two major differences between the transform and apply groupby methods.

• Input:
• apply implicitly passes all the columns for each group as a DataFrame to the custom function.
• while transform passes each column for each group individually as a Series to the custom function.
• Output:
• The custom function passed to apply can return a scalar, or a Series or DataFrame (or numpy array or even list).
• The custom function passed to transform must return a sequence (a one dimensional Series, array or list) the same length as the group.

So, transform works on just one Series at a time and apply works on the entire DataFrame at once.

Inspecting the custom function

It can help quite a bit to inspect the input to your custom function passed to apply or transform.

Examples

Let's create some sample data and inspect the groups so that you can see what I am talking about:

import pandas as pd
import numpy as np
df = pd.DataFrame({'State':['Texas', 'Texas', 'Florida', 'Florida'], 
                   'a':[4,5,1,3], 'b':[6,10,3,11]})

     State  a   b
0    Texas  4   6
1    Texas  5  10
2  Florida  1   3
3  Florida  3  11

Let's create a simple custom function that prints out the type of the implicitly passed object and then raised an error so that execution can be stopped.

def inspect(x):
    print(type(x))
    raise

Now let's pass this function to both the groupby apply and transform methods to see what object is passed to it:

df.groupby('State').apply(inspect)

<class 'pandas.core.frame.DataFrame'>
<class 'pandas.core.frame.DataFrame'>
RuntimeError

As you can see, a DataFrame is passed into the inspect function. You might be wondering why the type, DataFrame, got printed out twice. Pandas runs the first group twice. It does this to determine if there is a fast way to complete the computation or not. This is a minor detail that you shouldn't worry about.

Now, let's do the same thing with transform

df.groupby('State').transform(inspect)
<class 'pandas.core.series.Series'>
<class 'pandas.core.series.Series'>
RuntimeError

It is passed a Series - a totally different Pandas object.

So, transform is only allowed to work with a single Series at a time. It is impossible for it to act on two columns at the same time. So, if we try and subtract column a from b inside of our custom function we would get an error with transform. See below:

def subtract_two(x):
    return x['a'] - x['b']

df.groupby('State').transform(subtract_two)
KeyError: ('a', 'occurred at index a')

We get a KeyError as pandas is attempting to find the Series index a which does not exist. You can complete this operation with apply as it has the entire DataFrame:

df.groupby('State').apply(subtract_two)

State     
Florida  2   -2
         3   -8
Texas    0   -2
         1   -5
dtype: int64

The output is a Series and a little confusing as the original index is kept, but we have access to all columns.

Displaying the passed pandas object

It can help even more to display the entire pandas object within the custom function, so you can see exactly what you are operating with. You can use print statements by I like to use the display function from the IPython.display module so that the DataFrames get nicely outputted in HTML in a jupyter notebook:

from IPython.display import display
def subtract_two(x):
    display(x)
    return x['a'] - x['b']

Screenshot:

Transform must return a single dimensional sequence the same size as the group

The other difference is that transform must return a single dimensional sequence the same size as the group. In this particular instance, each group has two rows, so transform must return a sequence of two rows. If it does not then an error is raised:

def return_three(x):
    return np.array([1, 2, 3])

df.groupby('State').transform(return_three)
ValueError: transform must return a scalar value for each group

The error message is not really descriptive of the problem. You must return a sequence the same length as the group. So, a function like this would work:

def rand_group_len(x):
    return np.random.rand(len(x))

df.groupby('State').transform(rand_group_len)

          a         b
0  0.962070  0.151440
1  0.440956  0.782176
2  0.642218  0.483257
3  0.056047  0.238208

Returning a single scalar object also works for transform

If you return just a single scalar from your custom function, then transform will use it for each of the rows in the group:

def group_sum(x):
    return x.sum()

df.groupby('State').transform(group_sum)

   a   b
0  9  16
1  9  16
2  4  14
3  4  14

Change this line:

mMyListView.setAdapter(new ArrayAdapter<String>(this, 
                           android.R.layout.simple_list_item_1, 
                           listItems));

to:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                   android.R.layout.simple_list_item_1, 
                                   listItems)
mMyListView.setAdapter(adapter);

and after updating the value of a list item, call:

adapter.notifyDataSetChanged();

You don't need to store the column to reference it that way. Try this:

To set up:

CREATE TABLE tbl
  (zipcode text NOT NULL, city text NOT NULL, state text NOT NULL);
INSERT INTO tbl VALUES ('10954', 'Nanuet', 'NY');

We can see we have "the right stuff":

\pset border 2
SELECT * FROM tbl;

+---------+--------+-------+
| zipcode |  city  | state |
+---------+--------+-------+
| 10954   | Nanuet | NY    |
+---------+--------+-------+

Now add a function with the desired "column name" which takes the record type of the table as its only parameter:

CREATE FUNCTION combined(rec tbl)
  RETURNS text
  LANGUAGE SQL
AS $$
  SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;
$$;

This creates a function which can be used as if it were a column of the table, as long as the table name or alias is specified, like this:

SELECT *, tbl.combined FROM tbl;

Which displays like this:

+---------+--------+-------+--------------------+
| zipcode |  city  | state |      combined      |
+---------+--------+-------+--------------------+
| 10954   | Nanuet | NY    | 10954 - Nanuet, NY |
+---------+--------+-------+--------------------+

This works because PostgreSQL checks first for an actual column, but if one is not found, and the identifier is qualified with a relation name or alias, it looks for a function like the above, and runs it with the row as its argument, returning the result as if it were a column. You can even index on such a "generated column" if you want to do so.

Because you're not using extra space in each row for the duplicated data, or firing triggers on all inserts and updates, this can often be faster than the alternatives.

Here is a pure python method for simple strings, left here for posterity.

def string2bits(s=''):
    return [bin(ord(x))[2:].zfill(8) for x in s]

def bits2string(b=None):
    return ''.join([chr(int(x, 2)) for x in b])

s = 'Hello, World!'
b = string2bits(s)
s2 = bits2string(b)

print 'String:'
print s

print '\nList of Bits:'
for x in b:
    print x

print '\nString:'
print s2

String:

Here's what I did:

• Extracted the files using WinRAR
• Made my changes to the extracted files
• Opened the original JAR file with WinRAR
• Used the ADD button to replace the files that I modified

That's it. I have tested it with my Nokia and it's working for me.

I saw this problem before, when the (sub)folder I was trying to add had its name begin with "_Something_"

I removed the underscores and it worked. Check to see if your folder has characters which may be causing problems.

SnowsPenultimateNormalityTest certainly has its virtues, but you may also want to look at qqnorm.

X <- rlnorm(100)
qqnorm(X)
qqnorm(rnorm(100))

You need to make the decode function return an array by passing in the true parameter.

json_decode(file_get_contents($file),true);

See purl.js. This will really help and can also be used, depending on jQuery. Use it like this:

$.url().param("yourparam");

Not without writing your own class loader. You can add jars to the jar's classpath, but they must be co-located, not contained in the main jar.

Hello developers,

Please try this code

var default_date=  new Date(); // or your date
$('#datetimepicker').datetimepicker({
    format: 'DD/MM/YYYY HH:mm', // format you want to show on datetimepicker
    useCurrent:false, // default this is set to true
    defaultDate: default_date
});

if you want to set default date then please set useCurrent to false otherwise setDate or defaultDate like methods will not work.

Use insert:

In [1]: ls = [1,2,3]

In [2]: ls.insert(0, "new")

In [3]: ls
Out[3]: ['new', 1, 2, 3]

The accepted answer returns the discovered elements more or less unordered, by following the first child branch as deep as possible, while yielding the discovered elements along the way, before backtracking and repeating the steps for not yet parsed tree branches.

If you need the descendent elements in descending order, where the direct children will be yielded first, then their children and so on, the following algorithm will work:

public static IEnumerable<T> GetVisualDescendants<T>(DependencyObject parent, bool applyTemplates = false)
    where T : DependencyObject
{
    if (parent == null || !(child is Visual || child is Visual3D))
        yield break;

    var descendants = new Queue<DependencyObject>();
    descendants.Enqueue(parent);

    while (descendants.Count > 0)
    {
        var currentDescendant = descendants.Dequeue();

        if (applyTemplates)
            (currentDescendant as FrameworkElement)?.ApplyTemplate();

        for (var i = 0; i < VisualTreeHelper.GetChildrenCount(currentDescendant); i++)
        {
            var child = VisualTreeHelper.GetChild(currentDescendant, i);

            if (child is Visual || child is Visual3D)
                descendants.Enqueue(child);

            if (child is T foundObject)
                yield return foundObject;
        }
    }
}

The resulting elements will be ordered from nearest to farthest. This will be useful e.g. if you are looking for the nearest child element of some type and condition:

var foundElement = GetDescendants<StackPanel>(someElement)
                       .FirstOrDefault(o => o.SomeProperty == SomeState);

Easiest way do this is to remove filter, fill series from top of total data. Filter your desired data back in, copy list of numbers into a new sheet (this should be only the total lines you want to add numbering to) paste into column A1. Add "1" into column B1, right click and hold then drag down to end of numbers and choose "fill series". Now return to your list with filters and in the next column to the right "VLOOKUP" the filtered number against the list you pasted into a new sheet and return the 2nd value.

The best solution is to use:

domElement.click()

Because the angularjs triggerHandler(angular.element(domElement).triggerHandler('click')) click events does not bubble up in the DOM hierarchy, but the one above does - just like a normal mouse click.

Building on the previous answer by @BadPirate, I experimented a bit further and came up with some clarifications/corrections. I found that layoutSubviews: will be called on a view if and only if:

• Its own bounds (not frame) changed.
• The bounds of one of its direct subviews changed.
• A subview is added to the view or removed from the view.

Some relevant details:

• The bounds are considered changed only if the new value is different, including a different origin. Note specifically that is why layoutSubviews: is called whenever a UIScrollView scrolls, as it performs the scrolling by changing its bounds' origin.
• Changing the frame will only change the bounds if the size has changed, as this is the only thing propagated to the bounds property.
• A change in bounds of a view that is not yet in a view hierarchy will result in a call to layoutSubviews: when the view is eventually added to a view hierarchy.
• And just for completeness: these triggers do not directly call layoutSubviews, but rather call setNeedsLayout, which sets/raises a flag. Each iteration of the run loop, for all views in the view hierarchy, this flag is checked. For each view where the flag is found raised, layoutSubviews: is called on it and the flag is reset. Views higher up the hierarchy will be checked/called first.

To show result till yesterday

WHERE DATE(date_time) < CURDATE()

To show results of 10 days

WHERE date_time < NOW() - INTERVAL 10 DAY

To show results before 10 days

WHERE DATE(date_time) < DATE(NOW() - INTERVAL 10 DAY)

These will work for you

You can find dates like this

SELECT DATE(NOW() - INTERVAL 11 DAY)

but what I got is something like this: Date@124bbbf  
while I change the import to: import java.util.Date;  
the code works perfectly, why? 

What do you mean by "works perfectly"? The output of printing a Date object is the same no matter whether you imported java.util.* or java.util.Date. The output that you get when printing objects is the representation of the object by the toString() method of the corresponding class.

I had the same problem. I solve it with a for loop.

Example:

If I want to write in 2 identical tables, using a loop

for x = 0 to 1

 if x = 0 then TableToWrite = "Table1"
 if x = 1 then TableToWrite = "Table2"
  Sql = "INSERT INTO " & TableToWrite & " VALUES ('1','2','3')"
NEXT

either

ArrTable = ("Table1", "Table2")

for xArrTable = 0 to Ubound(ArrTable)
 Sql = "INSERT INTO " & ArrTable(xArrTable) & " VALUES ('1','2','3')"
NEXT

If you have a small query I don't know if this is the best solution, but if you your query is very big and it is inside a dynamical script with if/else/case conditions this is a good solution.

Try this query it ll change the records ends with .com

 UPDATE tablename SET email = replace(email, '.com', '.org') WHERE  email LIKE '%.com';

Count all the DISTINCT program names by program type and push number

SELECT COUNT(DISTINCT program_name) AS Count,
  program_type AS [Type] 
FROM cm_production 
WHERE push_number=@push_number 
GROUP BY program_type

DISTINCT COUNT(*) will return a row for each unique count. What you want is COUNT(DISTINCT <expression>): evaluates expression for each row in a group and returns the number of unique, non-null values.

Adding to Ophirs answer, JsonFormat is available even before protobuf 3.0. However, the way to do it differs a little bit.

In Protobuf 3.0+, the JsonFormat class is a singleton and therefore do something like the below

String jsonString = "";
JsonFormat.parser().ignoringUnknownFields().merge(jsonString,yourObjectBuilder);

In Protobuf 2.5+, the below should work

String jsonString = "";
JsonFormat jsonFormat = new JsonFormat();
jsonString = jsonFormat.printToString(yourProtobufMessage);

Here is a link to a tutorial I wrote that uses the JsonFormat class in a TypeAdapter that can be registered to a GsonBuilder object. You can then use Gson's toJson and fromJson methods to convert the proto data to Java and back.

Replying to jean . If we have the protobuf data in a file and want to parse it into a protobuf message object, use the merge method TextFormat class. See the below snippet:

// Let your proto text data be in a file MessageDataAsProto.prototxt
// Read it into string  
String protoDataAsString = FileUtils.readFileToString(new File("MessageDataAsProto.prototxt"));

// Create an object of the message builder
MyMessage.Builder myMsgBuilder = MyMessage.newBuilder();

// Use text format to parse the data into the message builder
TextFormat.merge(protoDataAsString, ExtensionRegistry.getEmptyRegistry(), myMsgBuilder);

// Build the message and return
return myMsgBuilder.build();

I had the same issue, and "git status" also showed no problem, then i just Restarted the holy GitHub client for windows and it worked like charm.

You could use the undocumented

DBCC LOG(databasename, typeofoutput)

where typeofoutput:

0: Return only the minimum of information for each operation -- the operation, its context and the transaction ID. (Default)
1: As 0, but also retrieve any flags and the log record length.
2: As 1, but also retrieve the object name, index name, page ID and slot ID.
3: Full informational dump of each operation.
4: As 3 but includes a hex dump of the current transaction log row.

For example, DBCC LOG(database, 1)

You could also try fn_dblog.

For rolling back a transaction using the transaction log I would take a look at Stack Overflow post Rollback transaction using transaction log.

You can get controller name or action name from action like any variable. They are just special (controller and action) and already defined so you do not need to do anything special to get them except telling you need them.

public string Index(string controller,string action)
   {
     var names=string.Format("Controller : {0}, Action: {1}",controller,action);
     return names;
   }

Or you can include controller , action in your models to get two of them and your custom data.

public class DtoModel
    {
        public string Action { get; set; }
        public string Controller { get; set; }
        public string Name { get; set; }
    }

public string Index(DtoModel baseModel)
    {
        var names=string.Format("Controller : {0}, Action: {1}",baseModel.Controller,baseModel.Action);
        return names;
    }

The names *args and **kwargs or **kw are purely by convention. It makes it easier for us to read each other's code

One place it is handy is when using the struct module

struct.unpack() returns a tuple whereas struct.pack() uses a variable number of arguments. When manipulating data it is convenient to be able to pass a tuple to struck.pack() eg.

tuple_of_data = struct.unpack(format_str, data)
... manipulate the data
new_data = struct.pack(format_str, *tuple_of_data)

without this ability you would be forced to write

new_data = struct.pack(format_str, tuple_of_data[0], tuple_of_data[1], tuple_of_data[2],...)

which also means the if the format_str changes and the size of the tuple changes, I'll have to go back and edit that really long line

Swift 1.1

extension String {
    var length: Int { return countElements(self) }  // 
}

Swift 1.2

extension String {
    var length: Int { return count(self)         }  // 
}

Swift 2.0

extension String {
    var length: Int { return characters.count    }  // 
}

Swift 4.2

extension String {
    var length: Int { return self.count }           
}

let str = "Hello"
let count = str.length    // returns 5 (Int)

You should also consider that the target has a padding and thus use position instead of offset. You can also account for a potential nav bar you don't want to be overlapping the target.

const $navbar = $('.navbar');

$('a[href^="#"]').on('click', function(e) {
    e.preventDefault();

    const scrollTop =
        $($(this).attr('href')).position().top -
        $navbar.outerHeight();

    $('html, body').animate({ scrollTop });
})

This it's because the mongod process it's down, you must to run the commands bellow in order to get up the mongod process:

Hope this helps you.

Despite finding an enormous number of question about the same problem (1, 2, 3, 4) I have never found an answer that took performance into consideration, even here.

Although multiple working solutions has been already given I would like to do a performance consideration.

EDIT: Thanks to Manatax for pointing out that option 1 does not suffer of performance issues.

Using Option 1 and 2, aka the COLLATE cast approach, can lead to potential bottleneck, cause any index defined on the column will not be used causing a full scan.

Even though I did not try out Option 3, my hunch is that it will suffer the same consequences of option 1 and 2.

Lastly, Option 4 is the best option for very large tables when it is viable. I mean there are no other usage that rely on the original collation.

Consider this simplified query:

SELECT 
    *
FROM
    schema1.table1 AS T1
        LEFT JOIN
    schema2.table2 AS T2 ON T2.CUI = T1.CUI
WHERE
    T1.cui IN ('C0271662' , 'C2919021')
;

In my original example, I had many more joins. Of course, table1 and table2 have different collations. Using the collate operator to cast, it will lead to indexes not being used.

See sql explanation in the picture below.

Visual Query Explanation when using the COLLATE cast

On the other hand, option 4 can take advantages of possible index and led to fast queries.

In the picture below, you can see the same query being run after applied Option 4, aka altering the schema/table/column collation.

Visual Query Explanation after the collation has been changed, and therefore without the collate cast

In conclusion, if performance are important and you can alter the collation of the table, go for Option 4. If you have to act on a single column, you can use something like this:

ALTER TABLE schema1.table1 MODIFY `field` VARCHAR(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Short answer is:

junk$nm[junk$nm %in% "B"] <- "b"

Take a look at Index vectors in R Introduction (if you don't read it yet).

EDIT. As noticed in comments this solution works for character vectors so fail on your data.

For factor best way is to change level:

levels(junk$nm)[levels(junk$nm)=="B"] <- "b"

If you are like me and don't always retrieve the axes, ax, when plotting the figure, then a simple solution would be to do

plt.xticks([])
plt.yticks([])

Just make a PKCS12 keystore, Java can use it directly now. In fact, if you list a Java-style keystore, keytool itself alerts you to the fact that PKCS12 is now the preferred format.

openssl pkcs12 -export -in server.crt -inkey server.key \
               -out server.p12 -name [some-alias] \
               -CAfile ca.crt -caname root -chain

You should have received all three files (server.crt, server.key, ca.crt) from your certificate provider. I am not sure what "-caname root" actually means, but it seems to have to be specified that way.

In the Java code, make sure to specify the right keystore type.

KeyStore.getInstance("PKCS12")

I got my comodo.com-issued SSL certificate working fine in NanoHTTPD this way.

One can also do this with a compact version of @TomAugspurger's answer, like so:

df = df1.merge(df2, how='left', on=['Year', 'Week', 'Colour']).merge(df3[['Week', 'Colour', 'Val3']], how='left', on=['Week', 'Colour'])

You try to append to second element in array, but it does not exist. Create it.

arr = [[]]

arr[0].append("aa1")
arr[0].append("aa2")
arr.append([])
arr[1].append("bb1")
arr[1].append("bb2")
arr[1].append("bb3")

using System;
using System.IO;
namespace FileOrDirectory
{
     class Program
     {
          public static string FileOrDirectory(string path)
          {
               if (File.Exists(path))
                    return "File";
               if (Directory.Exists(path))
                    return "Directory";
               return "Path Not Exists";
          }
          static void Main()
          {
               Console.WriteLine("Enter The Path:");
               string path = Console.ReadLine();
               Console.WriteLine(FileOrDirectory(path));
          }
     }
}

Line numbers are printed with grep -n:

grep -n pattern file.txt

To get only the line number (without the matching line), one may use cut:

grep -n pattern file.txt | cut -d : -f 1

Lines not containing a pattern are printed with grep -v:

grep -v pattern file.txt

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

If you can't change the datatype on the table itself to use varchar(max), then change your query to this:

SELECT *
FROM   [Village]
WHERE  CONVERT(VARCHAR(MAX), [CastleType]) = 'foo'

The QueryString collection is used to retrieve the variable values in the HTTP query string.

The HTTP query string is specified by the values following the question mark (?), like this:

Link with a query string

The line above generates a variable named txt with the value "this is a query string test".

Query strings are also generated by form submission, or by a user typing a query into the address bar of the browser.

RxJS6 (without compatibility package installed)

There's now an EMPTY constant and an empty function.

  import { Observable, empty, of } from 'rxjs';

  var delay = empty().pipe(delay(1000));     
  var delay2 = EMPTY.pipe(delay(1000));

Observable.empty() doesn't exist anymore.

You can set the width in pixels via inline styling:

<input type="text" name="text" style="width: 195px;">

You can also set the width with a visible character length:

<input type="text" name="text" size="35">

For adding argument to delay function.

First setup a dictionary then add it as the userInfo. Unwrap the info with the timer as the argument.

let arg : Int = 42
let infoDict : [String : AnyObject] = ["argumentInt", arg]

NSTimer.scheduledTimerWithTimeInterval(NSTimeInterval(3), target: self, selector: "functionHereWithArgument:", userInfo: infoDict, repeats: false)

Then in the called function

func functionHereWithArgument (timer : NSTimer)
{
    if let userInfo = timer.userInfo as? Dictionary<String, AnyObject>
    {
         let argumentInt : Int = (userInfo[argumentInt] as! Int)
    }
}

 DateTime dateTime = dateTime.Today.ToString("MM.dd.yyyy");

 Console.Write(dateTime);

JavaScript, as defined in your question, can't directly work with MySql. This is because it isn't running on the same computer.

JavaScript runs on the client side (in the browser), and databases usually exist on the server side. You'll probably need to use an intermediate server-side language (like PHP, Java, .Net, or a server-side JavaScript stack like Node.js) to do the query.

Here's a tutorial on how to write some code that would bind PHP, JavaScript, and MySql together, with code running both in the browser, and on a server:

http://www.w3schools.com/php/php_ajax_database.asp

And here's the code from that page. It doesn't exactly match your scenario (it does a query, and doesn't store data in the DB), but it might help you start to understand the types of interactions you'll need in order to make this work.

In particular, pay attention to these bits of code from that article.

Bits of Javascript:

xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();

Bits of PHP code:

mysql_select_db("ajax_demo", $con);
$result = mysql_query($sql);
// ...

Also, after you get a handle on how this sort of code works, I suggest you use the jQuery JavaScript library to do your AJAX calls. It is much cleaner and easier to deal with than the built-in AJAX support, and you won't have to write browser-specific code, as jQuery has cross-browser support built in. Here's the page for the jQuery AJAX API documentation.

The code from the article

HTML/Javascript code:

<html>
<head>
<script type="text/javascript">
function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>
</head>
<body>

<form>
<select name="users" onchange="showUser(this.value)">
<option value="">Select a person:</option>
<option value="1">Peter Griffin</option>
<option value="2">Lois Griffin</option>
<option value="3">Glenn Quagmire</option>
<option value="4">Joseph Swanson</option>
</select>
</form>
<br />
<div id="txtHint"><b>Person info will be listed here.</b></div>

</body>
</html>

PHP code:

<?php
$q=$_GET["q"];

$con = mysql_connect('localhost', 'peter', 'abc123');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("ajax_demo", $con);

$sql="SELECT * FROM user WHERE id = '".$q."'";

$result = mysql_query($sql);

echo "<table border='1'>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
<th>Hometown</th>
<th>Job</th>
</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td>" . $row['FirstName'] . "</td>";
  echo "<td>" . $row['LastName'] . "</td>";
  echo "<td>" . $row['Age'] . "</td>";
  echo "<td>" . $row['Hometown'] . "</td>";
  echo "<td>" . $row['Job'] . "</td>";
  echo "</tr>";
  }
echo "</table>";

mysql_close($con);
?>

Based on the above stuff:

import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

fontPath = "/usr/share/fonts/abc.ttf"
font = fm.FontProperties(fname=fontPath, size=10)
font2 = fm.FontProperties(fname=fontPath, size=24)

fig = plt.figure(figsize=(32, 24))
fig.text(0.5, 0.93, "This is my Title", horizontalalignment='center', fontproperties=font2)

plot = fig.add_subplot(1, 1, 1)

plot.xaxis.get_label().set_fontproperties(font)
plot.yaxis.get_label().set_fontproperties(font)
plot.legend(loc='upper right', prop=font)

for label in (plot.get_xticklabels() + plot.get_yticklabels()):
    label.set_fontproperties(font)

You can find all embeded code in 'Embeded Code' section and that looks like this

<iframe width="560" height="315"  src="https://www.youtube.com/embed/YOUR_VIDEO_CODE" frameborder="0" allowfullscreen></iframe>

Preferably put in a Util.java class

public static float dpFromPx(final Context context, final float px) {
    return px / context.getResources().getDisplayMetrics().density;
}

public static float pxFromDp(final Context context, final float dp) {
    return dp * context.getResources().getDisplayMetrics().density;

Subtracting 2 Date objects gives you the difference in milliseconds, e.g.:

var diff = Math.abs(new Date('2011/10/09 12:00') - new Date('2011/10/09 00:00'));

Math.abs is used to be able to use the absolute difference (so new Date('2011/10/09 00:00') - new Date('2011/10/09 12:00') gives the same result).

Dividing the result by 1000 gives you the number of seconds. Dividing that by 60 gives you the number of minutes. To round to whole minutes, use Math.floor or Math.ceil:

var minutes = Math.floor((diff/1000)/60);

In this example the result will be 720

You can try opening the wsdl in web browser and saving with .wsdl extension. And set the WSDL in SOAP UI project to this .wsdl file. This really works.

Since 2011a, the recommended way is:

booleanIndex = strcmp('KU', strs)

If you want to get the integer index (which you often don't need), you can use:

integerIndex = find(booleanIndex);

strfind is deprecated, so try not to use it.

Though not POSIX, bash 4 has the &> operator:

Just wanted to add an option that I started using because I use Azure SQL and the multiple table thing was way too cumbersome for me. I added an insert/update/delete trigger on my table and then converted the before/after change to json using the "FOR JSON AUTO" feature.

 SET @beforeJson = (SELECT * FROM DELETED FOR JSON AUTO)
SET @afterJson = (SELECT * FROM INSERTED FOR JSON AUTO)

That returns a JSON representation fo the record before/after the change. I then store those values in a history table with a timestamp of when the change occurred (I also store the ID for current record of concern). Using the serialization process, I can control how data is backfilled in the case of changes to schema.

I learned about this from this link here

Just to add on Jacek's perfect solution. If you're trying to do this in Kotlin, it wont work immediately. Instead, you'll want to use this:

@Throws(IOException::class)
fun getSplashVideo(context: Context): File {
    val cacheFile = File(context.cacheDir, "splash_video")
    try {
        val inputStream = context.assets.open("splash_video")
        val outputStream = FileOutputStream(cacheFile)
        try {
            inputStream.copyTo(outputStream)
        } finally {
            inputStream.close()
            outputStream.close()
        }
    } catch (e: IOException) {
        throw IOException("Could not open splash_video", e)
    }
    return cacheFile
}

Since R version 2.12, there's a droplevels() function.

levels(droplevels(subdf$letters))

If you have 2 arrays need to be merged based on values even its in different order

let arr1 = [
    { id:"1", value:"this", other: "that" },
    { id:"2", value:"this", other: "that" }
];

let arr2 = [
    { id:"2", key:"val2"},
    { id:"1", key:"val1"}
];

you can do like this

const result = arr1.map(item => {
    const obj = arr2.find(o => o.id === item.id);
    return { ...item, ...obj };
  });

console.log(result);

Listen to window:scroll event for window/document level scrolling and element's scroll event for element level scrolling.

window:scroll

@HostListener('window:scroll', ['$event'])
onWindowScroll($event) {

}

or

<div (window:scroll)="onWindowScroll($event)">

scroll

@HostListener('scroll', ['$event'])
onElementScroll($event) {

}

or

<div (scroll)="onElementScroll($event)">

@HostListener('scroll', ['$event']) won't work if the host element itself is not scroll-able.

Examples

• Using Event Binding
• Using HostListener

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

This worked for me.

.alert:not(:first-child){
    margin: 30px;
}

pip is included in Python installation. If you can't call pip.exe try calling python -m pip [args] from cmd

With argc (argument count) and argv (argument vector) you can get the number and the values of passed arguments when your application has been launched.

This way you can use parameters (such as -version) when your application is started to act a different way.

But you can also use int main(void) as a prototype in C.

There is a third (less known and nonstandard) prototype with a third argument which is envp. It contains environment variables.

Either escape the double quotes with \

String xmlString = "<element attribname=\"value\" attribname1=\"value1\"> pcdata</element>"

or use single quotes instead

String xmlString = "<element attribname='value' attribname1='value1'> pcdata</element>"

You call writer.close(); in writeToFile so the writer has been closed the second time you call writeToFile.

Why don't you merge FileStatus into writeToFile?

Just inject the routeParams service:

When you do from socket import * python is loading a socket module to the current namespace. Thus you can use module's members as if they are defined within your current python module.

When you do import socket, a module is loaded in a separate namespace. When you are accessing its members, you should prefix them with a module name. For example, if you want to refer to a socket class, you will need to write client_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM).

As for the problem with timeout - all you need to do is to change except socket.Timeouterror: to except timeout:, since timeout class is defined inside socket module and you have imported all its members to your namespace.

I know this is an old question, but here's an alternative. I'd store that image data in an array, then, on mouse move event over the canvas:

var index = (Math.floor(y) * canvasWidth + Math.floor(x)) * 4
var r = data[index]
var g = data[index + 1]
var b = data[index + 2]
var a = data[index + 3]

A lot easier than getting the imageData everytime.

this is simple solution for your question

LatLng coordinate = new LatLng(lat, lng);
CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(coordinate, 5);
map.animateCamera(yourLocation);

You can also use Edit Site List and make it be an exception so that you can run it from the specific website.

Beside of read.csv(url("...")) you also can use read.table("http://...").

Example:

> sample <- read.table("http://www.ats.ucla.edu/stat/examples/ara/angell.txt")
> sample
                V1   V2   V3   V4 V5
1        Rochester 19.0 20.6 15.0  E
2         Syracuse 17.0 15.6 20.2  E
...
43         Atlanta  4.2 70.6 32.6  S

With using pathlib module, indentation isn't needed.

import pathlib
pathlib.Path("output.txt").write_text("Purchase Amount: {}" .format(TotalAmount))

As of python 3.6, f-strings is available.

pathlib.Path("output.txt").write_text(f"Purchase Amount: {TotalAmount}")

You Can Also Check It:

cmd /c cd /d C:\activiti-5.9\setup & ant demo.start

As suggested this may be an issue with your compiler version.

Try using the following code to convert a long to std::string:

#include <sstream>
#include <string>
#include <iostream>

int main() {
    std::ostringstream ss;
    long num = 123456;
    ss << num;
    std::cout << ss.str() << std::endl;
}

either ceil and floor should give the same out out put

Math.ceil(x.y) == Math.floor(x.y)

or simply check for equality with double value

x.y == Math.ceil(x.y)
x.y == Math.floor(x.y)

or

Math.round(x.y) == x.y

This gives me the best result:

    Intent intent;
    if (android.os.Build.MANUFACTURER.equalsIgnoreCase("samsung")) {
        intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
        intent.putExtra("CONTENT_TYPE", "*/*");
        intent.addCategory(Intent.CATEGORY_DEFAULT);
    } else {

        String[] mimeTypes =
                {"application/msword", "application/vnd.openxmlformats-officedocument.wordprocessingml.document", // .doc & .docx
                        "application/vnd.ms-powerpoint", "application/vnd.openxmlformats-officedocument.presentationml.presentation", // .ppt & .pptx
                        "application/vnd.ms-excel", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", // .xls & .xlsx
                        "text/plain",
                        "application/pdf",
                        "application/zip", "application/vnd.android.package-archive"};

        intent = new Intent(Intent.ACTION_GET_CONTENT); // or ACTION_OPEN_DOCUMENT
        intent.setType("*/*");
        intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes);
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
    }

If you're trying to insert in to last_accessed_on, which is a DateTime2, then your issue is with the fact that you are converting it to a varchar in a format that SQL doesn't understand.

If you modify your code to this, it should work, note the format of your date has been changed to: YYYY-MM-DD hh:mm:ss:

UPDATE  student_queues 
SET  Deleted=0, 
     last_accessed_by='raja', 
     last_accessed_on=CONVERT(datetime2,'2014-07-23 09:37:00')
WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

Or if you want to use CAST, replace with:

CAST('2014-07-23 09:37:00.000' AS datetime2)

This is using the SQL ISO Date Format.

Just wanted to share here.

The install.packages command looks through the .libPaths variable. Here's what mine defaults to on OSX:

> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

I don't install packages there by default, I prefer to have them installed in my home directory. In my .Rprofile, I have this line:

.libPaths( "/Users/tex/lib/R" )

This adds the directory "/Users/tex/lib/R" to the front of the .libPaths variable.

Generic answer

This error is caused when you call a function that expects an Object as its argument, but pass undefined or null instead, like for example

Object.keys(null)
Object.assign(window.UndefinedVariable, {})

As that is usually by mistake, the solution is to check your code and fix the null/undefined condition so that the function either gets a proper Object, or does not get called at all.

Object.keys({'key': 'value'})
if (window.UndefinedVariable) {
    Object.assign(window.UndefinedVariable, {})
}

Answer specific to the code in question

The line if (obj === 'null') { return null;} // null unchanged will not evaluate when given null, only if given the string "null". So if you pass the actual null value to your script, it will be parsed in the Object part of the code. And Object.keys(null) throws the TypeError mentioned. To fix it, use if(obj === null) {return null} - without the qoutes around null.

A primary use case for a DTO is in returning data from a web service. In this instance, POCO and DTO are equivalent. Any behavior in the POCO would be removed when it is returned from a web service, so it doesn't really matter whether or not it has behavior.

Not exactly a setting but you can override the default TrustManager and HostnameVerifier to accept anything. Not a safe approach but in your situation, it can be acceptable.

To know if simple array has duplicates we can compare first and last indexes of the same value:

The function:

var hasDupsSimple = function(array) {

    return array.some(function(value) {                            // .some will break as soon as duplicate found (no need to itterate over all array)
       return array.indexOf(value) !== array.lastIndexOf(value);   // comparing first and last indexes of the same value
    })
}

Tests:

hasDupsSimple([1,2,3,4,2,7])
// => true

hasDupsSimple([1,2,3,4,8,7])
// => false

hasDupsSimple([1,"hello",3,"bye","hello",7])
// => true

For an array of objects we need to convert the objects values to a simple array first:

Converting array of objects to the simple array with map:

var hasDupsObjects = function(array) {

  return array.map(function(value) {
    return value.suit + value.rank

  }).some(function(value, index, array) { 
       return array.indexOf(value) !== array.lastIndexOf(value);  
     })
}

Tests:

var cardHand = [
  { "suit":"spades", "rank":"ten" },
  { "suit":"diamonds", "rank":"ace" },
  { "suit":"hearts", "rank":"ten" },
  { "suit":"clubs", "rank":"two" },
  { "suit":"spades", "rank":"three" },
]

hasDupsObjects(cardHand);
// => false

var cardHand2 = [
  { "suit":"spades", "rank":"ten" },
  { "suit":"diamonds", "rank":"ace" },
  { "suit":"hearts", "rank":"ten" },
  { "suit":"clubs", "rank":"two" },
  { "suit":"spades", "rank":"ten" },
]

hasDupsObjects(cardHand2);
// => true

No splits.. :) The correct/foolproof way is to let the native browser BUILT-IN functions do the heavy lifting using urlParams, the heavy lifting is done for you.

//summary answer - this one line will correctly replace in all current browsers
window.history.replaceState({}, '', `${location.pathname}?${params}`);

// 1 Get your URL 
let url = new URL('https://tykt.org?unicorn=1&printer=2&scanner=3');
console.log("URL: "+ url.toString());

// 2 get your params
let params = new URLSearchParams(url.search);
console.log("querys: " + params.toString());

// 3 Delete the printer param, Query string is now gone
params.delete('printer'); 
console.log("Printer Removed: " + params.toString()); 

// BELOW = Add it back to the URL, DONE!
___________

NOW Putting it all together in your live browser

// Above is a breakdown of how to get your params
// 4 then you simply replace those in your current browser!! 
window.history.replaceState({}, '', `${location.pathname}?${params}`);

You can specify a default value for the optional argument with something that would never passed to the function and check it with the is operator:

class _NO_DEFAULT:
    def __repr__(self):return "<no default>"
_NO_DEFAULT = _NO_DEFAULT()

def func(optional= _NO_DEFAULT):
    if optional is _NO_DEFAULT:
        print("the optional argument was not passed")
    else:
        print("the optional argument was:",optional)

then as long as you do not do func(_NO_DEFAULT) you can be accurately detect whether the argument was passed or not, and unlike the accepted answer you don't have to worry about side effects of ** notation:

# these two work the same as using **
func()
func(optional=1)

# the optional argument can be positional or keyword unlike using **
func(1) 

#this correctly raises an error where as it would need to be explicitly checked when using **
func(invalid_arg=7)

According to the standard (§6.4.4.4/10)

The value of an integer character constant containing more than one character (e.g., 'ab'), [...] is implementation-defined.

long x = '\xde\xad\xbe\xef'; // yes, single quotes

This is valid ISO 9899:2011 C. It compiles without warning under gcc with -Wall, and a “multi-character character constant” warning with -pedantic.

From Wikipedia:

Multi-character constants (e.g. 'xy') are valid, although rarely useful — they let one store several characters in an integer (e.g. 4 ASCII characters can fit in a 32-bit integer, 8 in a 64-bit one). Since the order in which the characters are packed into one int is not specified, portable use of multi-character constants is difficult.

For portability sake, don't use multi-character constants with integral types.

One more:

def month_converter(month):
    months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    return months.index(month) + 1

This worked for me to set ENABLE_BITCODE = NO via the command line:

find . -name *project.pbxproj | xargs sed -i -e 's/\(GCC_VERSION = "";\)/\1\ ENABLE_BITCODE = NO;/g'

Note that this is likely to be unstable across Xcode versions. It was tested with Xcode 7.0.1 and as part of a Cordova 4.0 project.

There have already been a bunch of great answers, but for an absolute beginner, I would wholeheartedly recommend Hackety Hack. It was created by the unreasonably prolific why_the_lucky_stiff specifically to provide a BASIC/LOGO/Pascal-like environment for new programmers to experiment in. It's essentially a slick Ruby IDE with some great libraries (flash video, IM, web server) and interactive lessons. It makes a good pitch for programming, as it chose lessons that do fun, useful things. "Hello, world" may not impress right off the bat, but creating a custom IM client in 20 minutes can inspire someone to keep learning. Have fun!

All those answers are wrong, since the release of gradle plugin v0.4.2 the setup of google play services under android studio is straight forward. You don't need to import any jar or add any project library nor add any new module under android studio. What you have to do is to add the correct dependencies into the build.gradle file. Please take a look to those links: Gradle plugin v0.4.2 update, New Build System, and this sample

The Correct way to do so is as follows:

First of all you have to launch the sdk manager and download and install the following files located under "extras": Android support repository, Google play services, Google repository.

Restart android studio and open the build gradle file. You must modify your build.gradle file to look like this under dependencies:

dependencies {
    compile 'com.google.android.gms:play-services:6.5.87' 
 }

And finally syncronise your project (the button to the left of the AVD manager).

Since version 6.5 you can include the complete library (very large) or just the modules that you need (Best Option). I.e if you only need Google Maps and Analytics you can replace the previous example with the following one:

dependencies {  
    compile 'com.google.android.gms:play-services-base:6.5.87'    
    compile 'com.google.android.gms:play-services-maps:6.5.87'  
}

You can find the complete dependency list here

Some side notes:

• Use the latest play services library version. If it's an old version, android studio will highlight it. As of today (February 5th is 6.5.87) but you can check the latest version at Gradle Please

• After a major update of Android Studio, clean an rebuild your project by following the next instructions as suggested in the comments by @user123321

  cd to your project folder
  ./gradlew clean
  ./gradlew build

You can find the log within you Magento root directory under

var/log

there are two types of log files system.log and exception.log

you need to give the correct permission to var folder, then enable logging from your Magento admin by going to

System > Configuration> Developer > Log Settings > Enable = Yes

system.log is used for general debugging and catches almost all log entries from Magento, including warning, debug and errors messages from both native and custom modules.

exception.log is reserved for exceptions only, for example when you are using try-catch statement.

To output to either the default system.log or the exception.log see the following code examples:

Mage::log('My log entry');
Mage::log('My log message: '.$myVariable);
Mage::log($myArray);
Mage::log($myObject);
Mage::logException($e);

You can create your own log file for more debugging

Mage::log('My log entry', null, 'mylogfile.log');

Just change the class container to container-fullwidth like this :

<div class="container-fullwidth">

The answer is neither.

Docker Compose (herein referred to as compose) will use the Dockerfile if you add the build command to your project's docker-compose.yml.

Your Docker workflow should be to build a suitable Dockerfile for each image you wish to create, then use compose to assemble the images using the build command.

You can specify the path to your individual Dockerfiles using build /path/to/dockerfiles/blah where /path/to/dockerfiles/blah is where blah's Dockerfile lives.

You can also load the context while defining the servlet itself (WebApplicationContext)

  <servlet>
    <servlet-name>admin</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>
                /WEB-INF/spring/*.xml
            </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>admin</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

rather than (ApplicationContext)

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext*.xml</param-value>
</context-param>

<listener>
   <listener-class>
        org.springframework.web.context.ContextLoaderListener
   </listener-class>
</listener> 

or can do both together.

Drawback of just using WebApplicationContext is that it will load context only for this particular Spring entry point (DispatcherServlet) where as with above mentioned methods context will be loaded for multiple entry points (Eg. Webservice Servlet, REST servlet etc)

Context loaded by ContextLoaderListener will infact be a parent context to that loaded specifically for DisplacherServlet . So basically you can load all your business service, data access or repository beans in application context and separate out your controller, view resolver beans to WebApplicationContext.

Try : java -version , then if you see java 11

try to delete with terminal : cd /Library/Java/JavaVirtualMachines rm -rf openjdk-11.0.1.jdk

if it doesn't try delete manually: 1) click on finder 2) go to folder 3) post /Library/Java/JavaVirtualMachines 4) delete java 11 .

then try java version and you will see : java version "1.8.0_191"

As others have stated, regular (traditional) functions use this from the object that called the function, (e.g. a button that was clicked). Instead, arrow functions use this from the object that defines the function.

Consider two almost identical functions:

regular = function() {
  ' Identical Part Here;
}


arrow = () => {
  ' Identical Part Here;
}

The snippet below demonstrates the fundamental difference between what this represents for each function. The regular function outputs [object HTMLButtonElement] whereas the arrow function outputs [object Window].

<html>_x000D_
 <button id="btn1">Regular: `this` comes from "this button"</button>_x000D_
 <br><br>_x000D_
 <button id="btn2">Arrow: `this` comes from object that defines the function</button>_x000D_
 <p id="res"/>_x000D_
_x000D_
 <script>_x000D_
  regular = function() {_x000D_
    document.getElementById("res").innerHTML = this;_x000D_
  }_x000D_
_x000D_
  arrow = () => {_x000D_
    document.getElementById("res").innerHTML = this;_x000D_
  }_x000D_
_x000D_
  document.getElementById("btn1").addEventListener("click", regular);_x000D_
  document.getElementById("btn2").addEventListener("click", arrow);_x000D_
 </script>_x000D_
</html>

Use any one solution (out of below 3)

(1) PHPMyAdmin

if you are using phpMyAdmin then change the "sql_mode" setting as mentioned in the below screenshot.

Edit "sql mode" variable and remove the "ONLY_FULL_GROUP_BY" text from the value

OR

(2) SQL/Command prompt Run the below command.

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

OR

(3) Don't use SELECT *

Use relevant column in SELECT query. relevant means columns, which are either coming in "group by" clause or column with the aggregate function (MAX, MIN, SUM, COUNT etc)

Important note

Changes made by using point(1) OR point(2) does not set it PERMANENTLY, and it will revert after every restart.

So you should set this in your config file (e.g. /etc/mysql/my.cnf in the [mysqld] section), so that the changes remain in effect after MySQL restart:

Config File: /etc/mysql/my.cnf

Variable name : sql_mode OR sql-mode

Remove word ONLY_FULL_GROUP_BY from the value and save the file.

Note : If you have not found "sql_mode" variable in the config file than please insert below 2 lines at the end of the file

[mysqld]
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

I also like itertuples()

for row in df.itertuples():
    print(row.A)
    print(row.Index)

since row is a named tuples, if you meant to access values on each row this should be MUCH faster

speed run :

df = pd.DataFrame([x for x in range(1000*1000)], columns=['A'])
st=time.time()
for index, row in df.iterrows():
    row.A
print(time.time()-st)
45.05799984931946

st=time.time()
for row in df.itertuples():
    row.A
print(time.time() - st)
0.48400020599365234

There is a library called BoofCV which claims to better than ZBar and other libraries.
Here are the steps to use that (any OS).

Pre-requisites:

• Ensure JDK 14+ is installed and set in $PATH
• pip install pyboof

Class to decode:

import os
import numpy as np
import pyboof as pb

pb.init_memmap() #Optional

class QR_Extractor:
    # Src: github.com/lessthanoptimal/PyBoof/blob/master/examples/qrcode_detect.py
    def __init__(self):
        self.detector = pb.FactoryFiducial(np.uint8).qrcode()
    
    def extract(self, img_path):
        if not os.path.isfile(img_path):
            print('File not found:', img_path)
            return None
        image = pb.load_single_band(img_path, np.uint8)
        self.detector.detect(image)
        qr_codes = []
        for qr in self.detector.detections:
            qr_codes.append({
                'text': qr.message,
                'points': qr.bounds.convert_tuple()
            })
        return qr_codes

Usage:

qr_scanner = QR_Extractor()
output = qr_scanner.extract('Your-Image.jpg')
print(output)

Tested and works on Python 3.8 (Windows & Ubuntu)

Use this, I think I can get your idea.

It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.

Changing the version in the pom.xml should fix the problem

I wrote some code to do this, i'll put in a few snippets:

$dir = getcwd(); // Get current working directory where this .php script lives
$fileList = scandir($dir); // scan the directory where this .php lives and make array of file names

Then get the CSV headers so you can tell mysql how to import (note: make sure your mysql columns exactly match the csv columns):

//extract headers from .csv for use in import command
$headers = str_replace("\"", "`", array_shift(file($path)));
$headers = str_replace("\n", "", $headers);

Then send your query to the mysql server:

mysqli_query($cons, '
        LOAD DATA LOCAL INFILE "'.$path.'"
            INTO TABLE '.$dbTable.'  
            FIELDS TERMINATED by \',\' ENCLOSED BY \'"\'
            LINES TERMINATED BY \'\n\'
            IGNORE 1 LINES
            ('.$headers.')
            ;
        ')or die(mysql_error());

If your application uses async stuff and you're fiddling with Mouse's cursor, you probably want to do it only in main UI thread. You can use app's Dispatcher thread for that:

Application.Current.Dispatcher.Invoke(() =>
{
    // The check is required to prevent cursor flickering
    if (Mouse.OverrideCursor != cursor)
        Mouse.OverrideCursor = cursor;
});

Based on VonC's suggestion, this worked for me (was driving me crazy):

git config --global core.editor "'C:/Program Files (x86)/Sublime Text 3/subl.exe' -wait"

Omitting -wait can cause problems, especially if you are working with Gerrit and change ids that have to be manually copied to the bottom of your commit message.

This looks like JavaScript Object Notation (JSON). You can parse JSON that resides in some variable, e.g. json_string, like so:

require 'json'
JSON.parse(json_string)

If you’re using an older Ruby, you may need to install the json gem.

There are also other implementations of JSON for Ruby that may fit some use-cases better:

• YAJL C Bindings for Ruby
• JSON::Stream

Differences in SOAP versions

Both SOAP Version 1.1 and SOAP Version 1.2 are World Wide Web Consortium (W3C) standards. Web services can be deployed that support not only SOAP 1.1 but also support SOAP 1.2. Some changes from SOAP 1.1 that were made to the SOAP 1.2 specification are significant, while other changes are minor.

The SOAP 1.2 specification introduces several changes to SOAP 1.1. This information is not intended to be an in-depth description of all the new or changed features for SOAP 1.1 and SOAP 1.2. Instead, this information highlights some of the more important differences between the current versions of SOAP.

The changes to the SOAP 1.2 specification that are significant include the following updates: SOAP 1.1 is based on XML 1.0. SOAP 1.2 is based on XML Information Set (XML Infoset). The XML information set (infoset) provides a way to describe the XML document with XSD schema. However, the infoset does not necessarily serialize the document with XML 1.0 serialization on which SOAP 1.1 is based.. This new way to describe the XML document helps reveal other serialization formats, such as a binary protocol format. You can use the binary protocol format to compact the message into a compact format, where some of the verbose tagging information might not be required.

In SOAP 1.2 , you can use the specification of a binding to an underlying protocol to determine which XML serialization is used in the underlying protocol data units. The HTTP binding that is specified in SOAP 1.2 - Part 2 uses XML 1.0 as the serialization of the SOAP message infoset.

SOAP 1.2 provides the ability to officially define transport protocols, other than using HTTP, as long as the vendor conforms to the binding framework that is defined in SOAP 1.2. While HTTP is ubiquitous, it is not as reliable as other transports including TCP/IP and MQ. SOAP 1.2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that might lead to interoperability errors in the absence of the Web Services-Interoperability (WS-I) profiles. The goal is to significantly reduce the chances of interoperability issues between different vendors that use SOAP 1.2 implementations. SOAP with Attachments API for Java (SAAJ) can also stand alone as a simple mechanism to issue SOAP requests. A major change to the SAAJ specification is the ability to represent SOAP 1.1 messages and the additional SOAP 1.2 formatted messages. For example, SAAJ Version 1.3 introduces a new set of constants and methods that are more conducive to SOAP 1.2 (such as getRole(), getRelay()) on SOAP header elements. There are also additional methods on the factories for SAAJ to create appropriate SOAP 1.1 or SOAP 1.2 messages. The XML namespaces for the envelope and encoding schemas have changed for SOAP 1.2. These changes distinguish SOAP processors from SOAP 1.1 and SOAP 1.2 messages and supports changes in the SOAP schema, without affecting existing implementations. Java Architecture for XML Web Services (JAX-WS) introduces the ability to support both SOAP 1.1 and SOAP 1.2. Because JAX-RPC introduced a requirement to manipulate a SOAP message as it traversed through the run time, there became a need to represent this message in its appropriate SOAP context. In JAX-WS, a number of additional enhancements result from the support for SAAJ 1.3.

There is not difine POST AND GET method for particular android....but all here is differance

GET The GET method appends name/value pairs to the URL, allowing you to retrieve a resource representation. The big issue with this is that the length of a URL is limited (roughly 3000 char) resulting in data loss should you have to much stuff in the form on your page, so this method only works if there is a small number parameters.

What does this mean for me? Basically this renders the GET method worthless to most developers in most situations. Here is another way of looking at it: the URL could be truncated (and most likely will be give today's data-centric sites) if the form uses a large number of parameters, or if the parameters contain large amounts of data. Also, parameters passed on the URL are visible in the address field of the browser (YIKES!!!) not the best place for any kind of sensitive (or even non-sensitive) data to be shown because you are just begging the curious user to mess with it.

POST The alternative to the GET method is the POST method. This method packages the name/value pairs inside the body of the HTTP request, which makes for a cleaner URL and imposes no size limitations on the forms output, basically its a no-brainer on which one to use. POST is also more secure but certainly not safe. Although HTTP fully supports CRUD, HTML 4 only supports issuing GET and POST requests through its various elements. This limitation has held Web applications back from making full use of HTTP, and to work around it, most applications overload POST to take care of everything but resource retrieval.

<input onchange="readURL(this);"  type="file" name="userfile" />
<img src="" id="blah"/>

 function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah')
                    .attr('src', e.target.result)
                    .width(150).height(200);
        };

        reader.readAsDataURL(input.files[0]);
        //console.log(reader);
        //alert(reader.readAsDataURL(input.files[0]));

The only time I've wanted to do this is for code golf, and then I've just copied my code out of the file and pasted it into an echo -n 'content'>file statement.

Map :

1. It processes one row at a time , very similar to map() method of MapReduce.
2. You return from the transformation after every row.

MapPartitions

1. It processes the complete partition in one go.
2. You can return from the function only once after processing the whole partition.
3. All intermediate results needs to be held in memory till you process the whole partition.
4. Provides you like setup() map() and cleanup() function of MapReduce

In JPQL the same is actually true in the spec. The JPA spec does not allow an alias to be given to a fetch join. The issue is that you can easily shoot yourself in the foot with this by restricting the context of the join fetch. It is safer to join twice.

This is normally more an issue with ToMany than ToOnes. For example,

Select e from Employee e 
join fetch e.phones p 
where p.areaCode = '613'

This will incorrectly return all Employees that contain numbers in the '613' area code but will left out phone numbers of other areas in the returned list. This means that an employee that had a phone in the 613 and 416 area codes will loose the 416 phone number, so the object will be corrupted.

Granted, if you know what you are doing, the extra join is not desirable, some JPA providers may allow aliasing the join fetch, and may allow casting the Criteria Fetch to a Join.

1. How is Atom different from Sublime?
   • Atom is an open source text editor/IDE, built on JavaScript/HTML/CSS.
   • Sublime Text is a commercial product, built on C/C++ and Python.
   • Comparable to Atom is Adobe Brackets, another open source text editor/IDE built on JavaScript/HTML/CSS. Be minded that this makes Brackets more oriented towards Web development, specially in the front end.
   • Advantages of open source projects are faster rate of development and, of course, price.
2. Does it include IDE features like build tools, function definition jumps, documentations, etc.?
   • The short answer is yes, yes, and yes. The app is completely modular. Open source will give people the freedom to fill the gaps on several of these features.
3. Has anyone using Sublime got a Beta invitation to point out the differences?
   • Advantages of Atom is entry-level hackability, since it's built on the same code that powers Web sites.
   • Advantages of Sublime Text is performance, as it doesn't need to run on top of Node.js, and it's a more mature product, about to reach a stable version 3.
   • There are a long list of minor differences that can be included in the comments (I wish this markdown could be able to draw a table for comparisons, but that's another issue).
   • Because of Atom's rapid turnout, I am afraid some of differences I list here will become outdated over time. Per example, at the time of this writing, Atom is only available on the Macintosh while Sublime Text is already multiplatform.
4. Can I use the themes, schemes and packages from Sublime as is, like Sublime could do with text mate.
   • The short answer is no, but because of Atom's hackability, it will be easy to retool packages from other editors to Atom.

If you have a project ready and just want to change some code and then build. Check out MSBuild which is located in the Microsoft.Net under windows directory.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild "C:\Projects\MyProject.csproj" /p:Configuration=Debug;DeployOnBuild=True;PackageAsSingleFile=False;outdir=C:\Projects\MyProjects\Publish\

(Please do not edit, leave as a single line)

... The line above broken up for readability

C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild "C:\Projects\MyProject.csproj"
/p:Configuration=Debug;DeployOnBuild=True;PackageAsSingleFile=False;
outdir=C:\Projects\MyProjects\Publish\

which is good alternative, especially when you operate on matrices (check ?which and notice the arr.ind argument). But I suggest that you stick with sum, because of na.rm argument that can handle NA's in logical vector. For instance:

# create dummy variable
set.seed(100)
x <- round(runif(100, 0, 1))
x <- x == 1
# create NA's
x[seq(1, length(x), 7)] <- NA

If you type in sum(x) you'll get NA as a result, but if you pass na.rm = TRUE in sum function, you'll get the result that you want.

> sum(x)
[1] NA
> sum(x, na.rm=TRUE)
[1] 43

Is your question strictly theoretical, or you have some practical problem concerning logical vectors?

EDIT: Since the answer is not valid with newer versions of jquery As jQuery.browser is deprecated in ver 1.9, So Use Jquery Migrate Plugin for that matter.

Original Answer

jQuery.browser

jQuery.browser and jQuery.browser.version

is your way to go...

Using parameter binding is definitely the way to go here. Not only is it very quick to write (just add [Parameter(Mandatory=$true)] above your mandatory parameters), but it's also the only option that you won't hate yourself for later.

More below:

[Console]::ReadLine is explicitly forbidden by the FxCop rules for PowerShell. Why? Because it only works in PowerShell.exe, not PowerShell ISE, PowerGUI, etc.

Read-Host is, quite simply, bad form. Read-Host uncontrollably stops the script to prompt the user, which means that you can never have another script that includes the script that uses Read-Host.

You're trying to ask for parameters.

You should use the [Parameter(Mandatory=$true)] attribute, and correct typing, to ask for the parameters.

If you use this on a [SecureString], it will prompt for a password field. If you use this on a Credential type, ([Management.Automation.PSCredential]), the credentials dialog will pop up, if the parameter isn't there. A string will just become a plain old text box. If you add a HelpMessage to the parameter attribute (that is, [Parameter(Mandatory = $true, HelpMessage = 'New User Credentials')]) then it will become help text for the prompt.

In my case I had the wrong case in

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

android.permission must be lowercase, and somehow the entire string was uppercase in our source.

The res argument in the http.get() callback is not the body, but rather an http.ClientResponse object. You need to assemble the body:

var url = 'http://graph.facebook.com/517267866/?fields=picture';

http.get(url, function(res){
    var body = '';

    res.on('data', function(chunk){
        body += chunk;
    });

    res.on('end', function(){
        var fbResponse = JSON.parse(body);
        console.log("Got a response: ", fbResponse.picture);
    });
}).on('error', function(e){
      console.log("Got an error: ", e);
});

Either use a User Defined Table

Or you can use CSV by defining your own CSV function as per This Post.

I'd probably recommend the second method, as your stored proc is already written in the correct format and you'll find it handy later on if you need to do this down the road.

Cheers!

Yow can change the DropDownStyle in properties to DropDownList. This will not show the TextBox for filter.

I made a test app for silent installs, using PackageManager.installPackage method.

I get installPackage method through reflection, and made android.content.pm.IPackageInstallObserver interface in my src folder (because it's hidden in android.content.pm package).

When i run installPackage, i got SecurityException with string indication, that my app has no android.permission.INSTALL_PACKAGES, but it defined in AndroidManifest.xml.

So, i think, it's not possible to use this method.

PS. I tested in on Android SDK 2.3 and 4.0. Maybe it will work with earlier versions.

use:

array.splice(2, 1);

This removes one item from the array, starting at index 2 (3rd item)

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

You may want to read:

• The Python Unicode HOWTO

• Pragmatic Unicode by Ned Batchelder

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky

before continuing.

If you are using mac, try giving root access to gradlew by doing

chmod +x ./gradlew

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

Just leave it empty: 'default_charset' in WHM :::::: default_charset =''

p.s. - In WHM go --------) Home »Service Configuration »PHP Configuration Editor ----) click 'Advanced Mode' ----) find 'default_charset' and leave it blank ---- just nothing, not utf8, not ISO

You can download gems from https://rubygems.org/gems/ or build you local gem via bundle and rack.

eg:

• bundle gem yourGemName
• rake install

Take care of installing dependencies before installing actual gems.

• gem install --local /pathToFolder/xxx-2.6.1.gem

Note: If using fluentd td-agent and ruby on same machine. Please make sure to use td-agent's td-agent-gem command. td-agent has own Ruby.

• In your app.component.html use:

    [ngStyle]="{'background-color':backcolor}"
  

• In app.ts declare variable of string type backcolor:string.

• Set the variable this.backcolor="red".

To keep a list of files, one can use:

rm(list=setdiff(ls(), c("df1", "df2")))

If you used...

$(function(){
    function myFunc() {
        // ... do something ...
    };
    $('#saveBtn').click(myFunc);
});

... then it will be easier to unbind later.

The online documentation seems a little unclear, so I just performed a little test. Choosing to break on Thrown from the Exceptions dialog box causes the program execution to break on any exception, handled or unhandled. If you want to break on handled exceptions only, it seems your only recourse is to go through your code and put breakpoints on all your handled exceptions. This seems a little excessive, so it might be better to add a debug statement whenever you handle an exception. Then when you see that output, you can set a breakpoint at that line in the code.

You can try the below:

function formatAMPM() {
    var date = new Date();
    var currDate = date.getDate();
    var hours = date.getHours();
    var dayName = getDayName(date.getDay());
    var minutes = date.getMinutes();
    var monthName = getMonthName(date.getMonth());
    var year = date.getFullYear();
    var ampm = hours >= 12 ? 'pm' : 'am';
    hours = hours % 12;
    hours = hours ? hours : 12; // the hour '0' should be '12'
    minutes = minutes < 10 ? '0' + minutes : minutes;
    var strTime = dayName + ' ' + monthName + ' ' + currDate + ' ' + year + ' ' + hours + ':' + minutes + ' ' + ampm;
    alert(strTime);
}

function getMonthName(month) {
    var ar = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
    return ar[month];
}

function getDayName(day) {
    var ar1 = new Array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");
    return ar1[day];
}

EDIT: Refer here for a working demo.

This works reliably for me in my main sub.

Dim defDate1 As Date, defDate2 As Date

'** Set default date range to previous month
defDate1 = CDate(Month(Now) & "/1/" & Year(Now))
defDate1 = DateAdd("m", -1, defDate1)
defDate2 = DateAdd("d", -1, DateAdd("m", 1, defDate1))

assume you want one item to be clicked each time. Then this code works well. Let's take the listview name as stlist

stList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        // here i overide the onitemclick method in onitemclick listener
            public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {

            //color change
            //selected item colored

            for(int i=0; i<stList.getAdapter().getCount();i++)
            {
                stList.getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
            }

            parent.getChildAt(position).setBackgroundColor(Color.GRAY);

    });
