For those folks using Spring Boot 2.0+, you can use the following to setup a task that will run the app with a given set of profiles.

task bootRunDev(type: org.springframework.boot.gradle.tasks.run.BootRun, dependsOn: 'build') {
    group = 'Application'

    doFirst() {
        main = bootJar.mainClassName
        classpath = sourceSets.main.runtimeClasspath
        systemProperty 'spring.profiles.active', 'dev'
    }
}

Then you can simply run ./gradlew bootRunDev or similar from your IDE.

Please try this one option:

 task RunTest(type: Test) {
         systemProperty "spring.profiles.active", System.getProperty("DEV")
         include 'com/db/project/Test1.class'
     }

Handling polymorphism is either model-bound or requires lots of code with various custom deserializers. I'm a co-author of a JSON Dynamic Deserialization Library that allows for model-independent json deserialization library. The solution to OP's problem can be found below. Note that the rules are declared in a very brief manner.

public class SOAnswer {
    @ToString @Getter @Setter
    @AllArgsConstructor @NoArgsConstructor
    public static abstract class Animal {
        private String name;    
    }

    @ToString(callSuper = true) @Getter @Setter
    @AllArgsConstructor @NoArgsConstructor
    public static class Dog extends Animal {
        private String breed;
    }

    @ToString(callSuper = true) @Getter @Setter
    @AllArgsConstructor @NoArgsConstructor
    public static class Cat extends Animal {
        private String favoriteToy;
    }
    
    
    public static void main(String[] args) {
        String json = "[{"
                + "    \"name\": \"pluto\","
                + "    \"breed\": \"dalmatian\""
                + "},{"
                + "    \"name\": \"whiskers\","
                + "    \"favoriteToy\": \"mouse\""
                + "}]";
        
        // create a deserializer instance
        DynamicObjectDeserializer deserializer = new DynamicObjectDeserializer();
        
        // runtime-configure deserialization rules; 
        // condition is bound to the existence of a field, but it could be any Predicate
        deserializer.addRule(DeserializationRuleFactory.newRule(1, 
                (e) -> e.getJsonNode().has("breed"),
                DeserializationActionFactory.objectToType(Dog.class)));
        
        deserializer.addRule(DeserializationRuleFactory.newRule(1, 
                (e) -> e.getJsonNode().has("favoriteToy"),
                DeserializationActionFactory.objectToType(Cat.class)));
        
        List<Animal> deserializedAnimals = deserializer.deserializeArray(json, Animal.class);
        
        for (Animal animal : deserializedAnimals) {
            System.out.println("Deserialized Animal Class: " + animal.getClass().getSimpleName()+";\t value: "+animal.toString());
        }

Based on the work of Denis Nek, it works well if the sum of item's widths is smaller than the size of the container. other than that, it will make the recyclerview non scrollable and only will show subset of the data.

to solve this problem, i modified the solution alittle so that it choose the min of the provided size and calculated size. see below:

package com.linkdev.gafi.adapters;

import android.content.Context;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.view.ViewGroup;

import com.linkdev.gafi.R;

public class MyLinearLayoutManager extends LinearLayoutManager {

    public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout)    {
        super(context, orientation, reverseLayout);
        this.c = context;
    }


    private Context c;
    private int[] mMeasuredDimension = new int[2];


    @Override
    public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                          int widthSpec, int heightSpec) {
        final int widthMode = View.MeasureSpec.getMode(widthSpec);
        final int heightMode = View.MeasureSpec.getMode(heightSpec);
        final int widthSize = View.MeasureSpec.getSize(widthSpec);
        final int heightSize = View.MeasureSpec.getSize(heightSpec);



        int width = 0;
        int height = 0;
        for (int i = 0; i < getItemCount(); i++) {
            measureScrapChild(recycler, i,
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    mMeasuredDimension);

            if (getOrientation() == HORIZONTAL) {
                width = width + mMeasuredDimension[0];
                if (i == 0) {
                    height = mMeasuredDimension[1];
                }
            } else {
                height = height + mMeasuredDimension[1];
                if (i == 0) {
                    width = mMeasuredDimension[0];
                }
            }
        }


        switch (widthMode) {
            case View.MeasureSpec.EXACTLY:
                width = widthSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        switch (heightMode) {
            case View.MeasureSpec.EXACTLY:
                height = heightSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        int widthDesired = Math.min(widthSize,width);
        setMeasuredDimension(widthDesired, height);
    }

    private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                                   int heightSpec, int[] measuredDimension) {
        View view = recycler.getViewForPosition(position);
        if (view != null) {
            RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
            int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                    getPaddingLeft() + getPaddingRight(), p.width);
            int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                    getPaddingTop() + getPaddingBottom(), p.height);
            view.measure(childWidthSpec, childHeightSpec);
            measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
            measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
            recycler.recycleView(view);
        }
    }}

This error is fairly self-explanatory. Dictionary keys are unique and you cannot have more than one of the same key. To fix this, you should modify your code like so:

Dictionary<string, string> rct3Features = new Dictionary<string, string>();
Dictionary<string, string> rct4Features = new Dictionary<string, string>();

foreach (string line in rct3Lines) 
{
    string[] items = line.Split(new String[] { " " }, 2, StringSplitOptions.None);

    if (!rct3Features.ContainsKey(items[0]))
    {
        rct3Features.Add(items[0], items[1]);
    }

    ////To print out the dictionary (to see if it works)
    //foreach (KeyValuePair<string, string> item in rct3Features)
    //{
    //    Console.WriteLine(item.Key + " " + item.Value);
    //}
}

This simple if statement ensures that you are only attempting to add a new entry to the Dictionary when the Key (items[0]) is not already present.

With Web API 2.2: Request.GetOwinContext().Request.RemoteIpAddress

Dictionaries are specifically designed to do super fast key lookups. They are implemented as hashtables and the more entries the faster they are relative to other methods. Using the exception engine is only supposed to be done when your method has failed to do what you designed it to do because it is a large set of object that give you a lot of functionality for handling errors. I built an entire library class once with everything surrounded by try catch blocks once and was appalled to see the debug output which contained a seperate line for every single one of over 600 exceptions!

It's easy to detect the image orientation and replace the bitmap using:

 /**
 * Rotate an image if required.
 * @param img
 * @param selectedImage
 * @return
 */
private static Bitmap rotateImageIfRequired(Context context,Bitmap img, Uri selectedImage) {

    // Detect rotation
    int rotation = getRotation(context, selectedImage);
    if (rotation != 0) {
        Matrix matrix = new Matrix();
        matrix.postRotate(rotation);
        Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
        img.recycle();
        return rotatedImg;
    }
    else{
        return img;
    }
}

/**
 * Get the rotation of the last image added.
 * @param context
 * @param selectedImage
 * @return
 */
private static int getRotation(Context context,Uri selectedImage) {

    int rotation = 0;
    ContentResolver content = context.getContentResolver();

    Cursor mediaCursor = content.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                                       new String[] { "orientation", "date_added" },
                                       null, null, "date_added desc");

    if (mediaCursor != null && mediaCursor.getCount() != 0) {
        while(mediaCursor.moveToNext()){
            rotation = mediaCursor.getInt(0);
            break;
        }
    }
    mediaCursor.close();
    return rotation;
}

To avoid Out of memories with big images, I'd recommend you to rescale the image using:

private static final int MAX_HEIGHT = 1024;
private static final int MAX_WIDTH = 1024;
public static Bitmap decodeSampledBitmap(Context context, Uri selectedImage)
    throws IOException {

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    InputStream imageStream = context.getContentResolver().openInputStream(selectedImage);
    BitmapFactory.decodeStream(imageStream, null, options);
    imageStream.close();

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, MAX_WIDTH, MAX_HEIGHT);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    imageStream = context.getContentResolver().openInputStream(selectedImage);
    Bitmap img = BitmapFactory.decodeStream(imageStream, null, options);

    img = rotateImageIfRequired(img, selectedImage);
    return img;
}

It's not posible to use ExifInterface to get the orientation because an Android OS issue: https://code.google.com/p/android/issues/detail?id=19268

And here is calculateInSampleSize

/**
 * Calculate an inSampleSize for use in a {@link BitmapFactory.Options} object when decoding
 * bitmaps using the decode* methods from {@link BitmapFactory}. This implementation calculates
 * the closest inSampleSize that will result in the final decoded bitmap having a width and

 * ensure a power of 2 is returned for inSampleSize which can be faster when decoding but
 * results in a larger bitmap which isn't as useful for caching purposes.
 *
 * @param options   An options object with out* params already populated (run through a decode*

 * @return The value to be used for inSampleSize
 */
public static int calculateInSampleSize(BitmapFactory.Options options,
                                        int reqWidth, int reqHeight) {

    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will guarantee a final image
        // with both dimensions larger than or equal to the requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;

        // This offers some additional logic in case the image has a strange
        // aspect ratio. For example, a panorama may have a much larger
        // width than height. In these cases the total pixels might still
        // end up being too large to fit comfortably in memory, so we should
        // be more aggressive with sample down the image (=larger inSampleSize).

        final float totalPixels = width * height;

        // Anything more than 2x the requested pixels we'll sample down further
        final float totalReqPixelsCap = reqWidth * reqHeight * 2;

        while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
            inSampleSize++;
        }
    }
    return inSampleSize;
}

var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);

throws a parsing exception due to missing quotes around the first argument (I think). I got it to work by adding the quotes:

var i2 = JsonConvert.DeserializeObject("\"" + obj["id"].ToString() + "\"", type);

The first form, when used with an API that returns Boolean and compared against Boolean.FALSE, will never throw a NullPointerException.

The second form, when used with the java.util.Map interface, also, will never throw a NullPointerException because it returns a boolean and not a Boolean.

If you aren't concerned about consistent coding idioms, then you can pick the one you like, and in this concrete case it really doesn't matter. If you do care about consistent coding, then consider what you want to do when you check a Boolean that may be NULL.

In general, the way to deal with circular dependencies is to use setter injection.

I tried the setter injection code that you posted, and it worked for me. I would imagine the reason you are getting the exception is because Bean1 and Bean2 are in the com.myapp.beans package, and you don't have component scanning enabled for that package.

You'd need to add the following to your spring configuration:

<context:component-scan base-package="com.bullethq.accounts.web"/>

or move the beans to a package which is being automatically scanned by Spring.

I don't think any of these answers are quite right/optimal. NameValueCollection not only doesn't distinguish between null values and missing values, it's also case-insensitive with regards to it's keys. Thus, I think a full solution would be:

public static bool ContainsKey(this NameValueCollection @this, string key)
{
    return @this.Get(key) != null 
        // I'm using Keys instead of AllKeys because AllKeys, being a mutable array,
        // can get out-of-sync if mutated (it weirdly re-syncs when you modify the collection).
        // I'm also not 100% sure that OrdinalIgnoreCase is the right comparer to use here.
        // The MSDN docs only say that the "default" case-insensitive comparer is used
        // but it could be current culture or invariant culture
        || @this.Keys.Cast<string>().Contains(key, StringComparer.OrdinalIgnoreCase);
}

Just so you know...

Adding to the litany of woes with these classes, there is a rather interesting bug that's worth sharing.

I'm using a ViewPager to navigate a tree of items (select an item and the view pager animates scrolling to the right, and the next branch appears, navigate back, and the ViewPager scrolls in the opposite direction to return to the previous node).

The problem arises when I push and pop fragments off the end of the FragmentStatePagerAdapter. It's smart enough to notice that the items change, and smart enough to create and replace a fragment when the item has changed. But not smart enough to discard the fragment state, or smart enough to trim the internally saved fragment states when the adapter size changes. So when you pop an item, and push a new one onto the end, the fragment for the new item gets the saved state of the fragment for the old item, which caused absolute havoc in my code. My fragments carry data that may require a lot of work to refetch from the internet, so not saving state really wasn't an option.

I don't have a clean workaround. I used something like this:

  public void onSaveInstanceState(Bundle outState) {
    IFragmentListener listener = (IFragmentListener)getActivity();
    if (listener!= null)
    {
        if (!listener.isStillInTheAdapter(this.getAdapterItem()))
        {
            return; // return empty state.
        }

    }
    super.onSaveInstanceState(outState);

    // normal saving of state for flips and 
    // paging out of the activity follows
    ....
  }

An imperfect solution because the new fragment instance still gets a savedState Bundle, but at least it doesn't carry stale data.

I suspect the error is caused by this:

foreach (KeyValuePair<int, int> kvp in rankings)

rankings is a dictionary, which is IEnumerable. By using it in a foreach loop, you're specifying that you want each KeyValuePair from the dictionary in a deferred manner. That is, the next KeyValuePair is not returned until your loop iterates again.

But you're modifying the dictionary inside your loop:

rankings[kvp.Key] = rankings[kvp.Key] + 4;

which isn't allowed...so you get the exception.

You could simply do this

foreach (KeyValuePair<int, int> kvp in rankings.ToArray())

The question how do I convert an object to a String, despite the several answers you see here, and despite the existence of the Object.toString method, is unanswerable, or has infinitely many answers. Because what is being asked for is some kind of text representation or description of the object, and there are infinitely many possible representations. Each representation encodes a particular object instance using a special purpose language (probably a very limited language) or format that is expressive enough to encode all possible object instances.

Before code can be written to convert an object to a String, you must decide on the language/format to be used.

Could there be any problem if i replace Method-1 by Method-2?

No, just use map[key] = value. The two options are equivalent.

Regarding Dictionary<> vs. Hashtable: When you start Reflector, you see that the indexer setters of both classes call this.Insert(key, value, add: false); and the add parameter is responsible for throwing an exception, when inserting a duplicate key. So the behavior is the same for both classes.

Upper options gives flexible to all manner, if you know key type try parsing them bool.TryParse(ConfigurationManager.AppSettings["myKey"], out myvariable);

If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:

Dictionary<string, ArrayList> result = target.GetComponents()
                                      .ToDictionary(x => x.Key, x => x.Value);

There's no such thing as an IEnumerable<T1, T2> but a KeyValuePair<TKey, TValue> is fine.

TryGetValue will already assign the default value for the type to the dictionary, so you can just use:

dictionary.TryGetValue(key, out value);

and just ignore the return value. However, that really will just return default(TValue), not some custom default value (nor, more usefully, the result of executing a delegate). There's nothing more powerful built into the framework. I would suggest two extension methods:

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary, 
     TKey key,
     TValue defaultValue)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value : defaultValue;
}

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary,
     TKey key,
     Func<TValue> defaultValueProvider)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value
         : defaultValueProvider();
}

(You may want to put argument checking in, of course :)

All the answers here are great but, just to illustrate where this comes from, for questions like this it's good to go to the source: the Java Language Specification.

Section 15:23, Conditional-And operator (&&), says:

The && operator is like & (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is true. [...] At run time, the left-hand operand expression is evaluated first [...] if the resulting value is false, the value of the conditional-and expression is false and the right-hand operand expression is not evaluated. If the value of the left-hand operand is true, then the right-hand expression is evaluated [...] the resulting value becomes the value of the conditional-and expression. Thus, && computes the same result as & on boolean operands. It differs only in that the right-hand operand expression is evaluated conditionally rather than always.

And similarly, Section 15:24, Conditional-Or operator (||), says:

The || operator is like | (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is false. [...] At run time, the left-hand operand expression is evaluated first; [...] if the resulting value is true, the value of the conditional-or expression is true and the right-hand operand expression is not evaluated. If the value of the left-hand operand is false, then the right-hand expression is evaluated; [...] the resulting value becomes the value of the conditional-or expression. Thus, || computes the same result as | on boolean or Boolean operands. It differs only in that the right-hand operand expression is evaluated conditionally rather than always.

A little repetitive, maybe, but the best confirmation of exactly how they work. Similarly the conditional operator (?:) only evaluates the appropriate 'half' (left half if the value is true, right half if it's false), allowing the use of expressions like:

int x = (y == null) ? 0 : y.getFoo();

without a NullPointerException.

You just use the method

public Object put(Object key, Object value)

if the key was already present in the Map then the previous value is returned.

I suppose your dictMap is of type HashMap, which makes it default to HashMap<Object, Object>. If you want it to be more specific, declare it as HashMap<String, ArrayList>, or even better, as HashMap<String, ArrayList<T>>

1. Convert int[] to Integer[]

   public static Integer[] toConvertInteger(int[] ids) {
   
     Integer[] newArray = new Integer[ids.length];
        for (int i = 0; i < ids.length; i++) {
          newArray[i] = Integer.valueOf(ids[i]);
        }
      return newArray;
   }
   

2. Convert Integer[] to int[]

   public static int[] toint(Integer[] WrapperArray) {
   
      int[] newArray = new int[WrapperArray.length];
         for (int i = 0; i < WrapperArray.length; i++) {
            newArray[i] = WrapperArray[i].intValue();
         }
      return newArray;
   }
   

What about you declare the following "Key" class:

public class Key {
   public Object key1, key2, ..., keyN;

   public Key(Object key1, Object key2, ..., Object keyN) {
      this.key1 = key1;
      this.key2 = key2;
      ...
      this.keyN = keyN;
   }

   @Override   
   public boolean equals(Object obj) {
      if (!(obj instanceof Key))
        return false;
      Key ref = (Key) obj;
      return this.key1.equals(ref.key1) && 
          this.key2.equals(ref.key2) &&
          ...
          this.keyN.equals(ref.keyN)
   }

    @Override
    public int hashCode() {
        return key1.hashCode() ^ key2.hashCode() ^ 
            ... ^ keyN.hashCode();
    }

}

Declaring the Map

Map<Key, Double> map = new HashMap<Key,Double>();

Declaring the key object

Key key = new Key(key1, key2, ..., keyN)

Filling the map

map.put(key, new Double(0))

Getting the object from the map

Double result = map.get(key);

The information I give here is not new, I just added this for completeness.

The idea of this code is quite simple:

• Objects need a unique ID, which isn't there by default. Instead, we have to rely on the next best thing, which is RuntimeHelpers.GetHashCode to get us a sort-of unique ID
• To check uniqueness, this implies we need to use object.ReferenceEquals
• However, we would still like to have a unique ID, so I added a GUID, which is by definition unique.
• Because I don't like locking everything if I don't have to, I don't use ConditionalWeakTable.

Combined, that will give you the following code:

public class UniqueIdMapper
{
    private class ObjectEqualityComparer : IEqualityComparer<object>
    {
        public bool Equals(object x, object y)
        {
            return object.ReferenceEquals(x, y);
        }

        public int GetHashCode(object obj)
        {
            return RuntimeHelpers.GetHashCode(obj);
        }
    }

    private Dictionary<object, Guid> dict = new Dictionary<object, Guid>(new ObjectEqualityComparer());
    public Guid GetUniqueId(object o)
    {
        Guid id;
        if (!dict.TryGetValue(o, out id))
        {
            id = Guid.NewGuid();
            dict.Add(o, id);
        }
        return id;
    }
}

To use it, create an instance of the UniqueIdMapper and use the GUID's it returns for the objects.

Addendum

So, there's a bit more going on here; let me write a bit down about ConditionalWeakTable.

ConditionalWeakTable does a couple of things. The most important thing is that it doens't care about the garbage collector, that is: the objects that you reference in this table will be collected regardless. If you lookup an object, it basically works the same as the dictionary above.

Curious no? After all, when an object is being collected by the GC, it checks if there are references to the object, and if there are, it collects them. So if there's an object from the ConditionalWeakTable, why will the referenced object be collected then?

ConditionalWeakTable uses a small trick, which some other .NET structures also use: instead of storing a reference to the object, it actually stores an IntPtr. Because that's not a real reference, the object can be collected.

So, at this point there are 2 problems to address. First, objects can be moved on the heap, so what will we use as IntPtr? And second, how do we know that objects have an active reference?

• The object can be pinned on the heap, and its real pointer can be stored. When the GC hits the object for removal, it unpins it and collects it. However, that would mean we get a pinned resource, which isn't a good idea if you have a lot of objects (due to memory fragmentation issues). This is probably not how it works.
• When the GC moves an object, it calls back, which can then update the references. This might be how it's implemented judging by the external calls in DependentHandle - but I believe it's slightly more sophisticated.
• Not the pointer to the object itself, but a pointer in the list of all objects from the GC is stored. The IntPtr is either an index or a pointer in this list. The list only changes when an object changes generations, at which point a simple callback can update the pointers. If you remember how Mark & Sweep works, this makes more sense. There's no pinning, and removal is as it was before. I believe this is how it works in DependentHandle.

This last solution does require that the runtime doesn't re-use the list buckets until they are explicitly freed, and it also requires that all objects are retrieved by a call to the runtime.

If we assume they use this solution, we can also address the second problem. The Mark & Sweep algorithm keeps track of which objects have been collected; as soon as it has been collected, we know at this point. Once the object checks if the object is there, it calls 'Free', which removes the pointer and the list entry. The object is really gone.

One important thing to note at this point is that things go horribly wrong if ConditionalWeakTable is updated in multiple threads and if it isn't thread safe. The result would be a memory leak. This is why all calls in ConditionalWeakTable do a simple 'lock' which ensures this doesn't happen.

Another thing to note is that cleaning up entries has to happen once in a while. While the actual objects will be cleaned up by the GC, the entries are not. This is why ConditionalWeakTable only grows in size. Once it hits a certain limit (determined by collision chance in the hash), it triggers a Resize, which checks if objects have to be cleaned up -- if they do, free is called in the GC process, removing the IntPtr handle.

I believe this is also why DependentHandle is not exposed directly - you don't want to mess with things and get a memory leak as a result. The next best thing for that is a WeakReference (which also stores an IntPtr instead of an object) - but unfortunately doesn't include the 'dependency' aspect.

What remains is for you to toy around with the mechanics, so that you can see the dependency in action. Be sure to start it multiple times and watch the results:

class DependentObject
{
    public class MyKey : IDisposable
    {
        public MyKey(bool iskey)
        {
            this.iskey = iskey;
        }

        private bool disposed = false;
        private bool iskey;

        public void Dispose()
        {
            if (!disposed)
            {
                disposed = true;
                Console.WriteLine("Cleanup {0}", iskey);
            }
        }

        ~MyKey()
        {
            Dispose();
        }
    }

    static void Main(string[] args)
    {
        var dep = new MyKey(true); // also try passing this to cwt.Add

        ConditionalWeakTable<MyKey, MyKey> cwt = new ConditionalWeakTable<MyKey, MyKey>();
        cwt.Add(new MyKey(true), dep); // try doing this 5 times f.ex.

        GC.Collect(GC.MaxGeneration);
        GC.WaitForFullGCComplete();

        Console.WriteLine("Wait");
        Console.ReadLine(); // Put a breakpoint here and inspect cwt to see that the IntPtr is still there
    }

Collections.synchronizedMap() guarantees that each atomic operation you want to run on the map will be synchronized.

Running two (or more) operations on the map however, must be synchronized in a block. So yes - you are synchronizing correctly.

Quite simple, just use the built-in function in Map.java as followed

map.put(key, map.getOrDefault(key, 0) + 1);

Linux is now officially supported in brew - see the Homebrew 2.0.0 blog post. As shown on https://brew.sh, just copy/paste this into a command prompt:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

You can customize the JsonSerializerSettings by using the Formatters.JsonFormatter.SerializerSettings property in the HttpConfiguration object.

For example, you could do that in the Application_Start() method:

protected void Application_Start()
{
    HttpConfiguration config = GlobalConfiguration.Configuration;
    config.Formatters.JsonFormatter.SerializerSettings.Formatting =
        Newtonsoft.Json.Formatting.Indented;
}

I did solve this error by setting

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME

yes, not only $ORACLE_HOME/lib but $ORACLE_HOME too.

In the context of browser, Javascript can READ user-specified file. See Eric Bidelman's blog for detail about reading file using File API. However, it is not possible for browser-based Javascript to WRITE the file system of local computer without disabling some security settings because it is regarded as a security threat for any website to change your local file system arbitrarily.

Saying that, there are some ways to work around it depending what you are trying to do:

1. If it is your own site, you can embed a Java Applet in the web page. However, the visitor has to install Java on local machine and will be alerted about the security risk. The visitor has to allow the applet to be loaded. An Java Applet is like an executable software that has complete access to the local computer.

2. Chrome supports a file system which is a sandboxed portion of the local file system. See this page for details. This provides possibly for you to temporarily save things locally. However, this is not supported by other browsers.

3. If you are not limited to browser, Node.js has a complete file system interface. See here for its file system documentation. Note that Node.js can run not only on servers, but also any client computer including windows. The javascript test runner Karma is based on Node.js. If you just like to program in javascript on the local computer, this is an option.

In my case, adding a dtype attribute changed dtype of the array to a smaller type(from float64 to uint8), decreasing array size enough to not throw MemoryError in Windows(64 bit).

A simple JSF Url Prettyfier filter based in the steps of BalusC's answer. The filter forwards all the requests starting with the /ui path (supposing you've got all your xhtml files stored there) to the same path, but adding the xhtml suffix.

public class UrlPrettyfierFilter implements Filter {

    private static final String JSF_VIEW_ROOT_PATH = "/ui";

    private static final String JSF_VIEW_SUFFIX = ".xhtml";

    @Override
    public void destroy() {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest httpServletRequest = ((HttpServletRequest) request);
        String requestURI = httpServletRequest.getRequestURI();
        //Only process the paths starting with /ui, so as other requests get unprocessed. 
        //You can register the filter itself for /ui/* only, too
        if (requestURI.startsWith(JSF_VIEW_ROOT_PATH) 
                && !requestURI.contains(JSF_VIEW_SUFFIX)) {
            request.getRequestDispatcher(requestURI.concat(JSF_VIEW_SUFFIX))
                .forward(request,response);
        } else {
            chain.doFilter(httpServletRequest, response);
        }
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {

    }

}

without mapping ? the quicker lambda solution

Integer.toString( num ).chars().boxed().collect( Collectors.summingInt( (c) -> c - '0' ) );

…or same with the slower % operator

Integer.toString( num ).chars().boxed().collect( Collectors.summingInt( (c) -> c % '0' ) );

…or Unicode compliant

Integer.toString( num ).codePoints().boxed().collect( Collectors.summingInt( Character::getNumericValue ) );

The Maximally Standards Compliant way to do it is to create a text node containing the text you want and append it to the span (removing any currently extant text nodes).

The way I would actually do it is to use jQuery's .text().

Install the extension "Code Runner". Check if you can compile your program with csc (ex.: csc hello.cs). The command csc is shipped with Mono. Then add this to your VS Code user settings:

"code-runner.executorMap": {
        "csharp": "echo '# calling mono\n' && cd $dir && csc /nologo $fileName && mono $dir$fileNameWithoutExt.exe",
        // "csharp": "echo '# calling dotnet run\n' && dotnet run"
    }

Open your C# file and use the execution key of Code Runner.

Edit: also added dotnet run, so you can choose how you want to execute your program: with Mono, or with dotnet. If you choose dotnet, then first create the project (dotnet new console, dotnet restore).

It's easy for migrating iPhone5 and iPhone4 through XIBs.........

UIViewController *viewController3;

Cleaner way, exploit shortcut evaluation of shell logical operators. Right side of the operator is executed only if left side is true.

Google Drive folders can be embedded and displayed in list and grid views:

List view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>

Grid view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Q: What is a folder ID (FOLDER-ID) and how can I get it?

A: Go to Google Drive >> open the folder >> look at its URL in the address bar of your browser. For example:

Folder URL: https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Folder ID:
0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Caveat with folders requiring permission

This technique works best for folders with public access. Folders that are shared only with certain Google accounts will cause trouble when you embed them this way. At the time of this edit, a message "You need permission" appears, with some buttons to help you "Request access" or "Switch accounts" (or possibly sign-in to a Google account). The Javascript in these buttons doesn't work properly inside an IFRAME in Chrome.

To set permanent PuTTY session parameters do:

1. Create sessions in PuTTY. Name it as "MyskinPROD"

2. Configure the path for this session to point to "C:\dir\&Y&M&D&T_&H_putty.log".

3. Create a Windows "Shortcut" to C:...\Putty.exe.

4. Open "Shortcut" Properties and append "Target" line with parameters as shown below:

   "C:\Program Files (x86)\UTL\putty.exe" -ssh -load MyskinPROD user@ServerIP -pw password
   

Now, your PuTTY shortcut will bring in the "MyskinPROD" configuration every time you open the shortcut.

Ok, so in this application, there is an iframe in which the user is supplied with links or some capacity that allows that iframe to browse to some external site. You are then looking to capture the URL to which the user has browsed.

Something to keep in mind. Since the URL is to an external source, you will be limited in how much you can interact with this iframe via javascript (or an client side access for that matter), this is known as browser cross-domain security, as apparently you have discovered. There are clever work arounds, as presented here Cross-domain, cross-frame Javascript, although I do not think this work around applies in this case.

About all you can access is the location, as you need.

I would suggest making the code presented more resilitant and less error prone. Try browsing the web sometime with IE or FF configured to show javascript errors. You will be surprised just how many javascript errors are thrown, largely because there is a lot of error prone javascript out there, which just continues to proliferate.

This solution assumes that the iframe in question is the same "window" context where you are running the javascript. (Meaning, it is not embedded within another frame or iframe, in which case, the javascript code gets more involved, and you likely need to recursively search through the window hierarchy.)

<iframe name='frmExternal' id='frmExternal' src='http://www.stackoverflow.com'></frame>
<input type='text' id='txtUrl' />
<input type='button' id='btnGetUrl' value='Get URL' onclick='GetIFrameUrl();' />

<script language='javascript' type='text/javascript'>
function GetIFrameUrl()
{
    if (!document.getElementById)
    {
        return;
    }

    var frm = document.getElementById("frmExternal");
    var txt = document.getElementById("txtUrl");

    if (frm == null || txt == null)
    {
        // not great user feedback but slightly better than obnoxious script errors
       alert("There was a problem with this page, please refresh.");
       return;
    }

    txt.value = frm.src;
}
</script>

Hope this helps.

All of these are kinds of indices.

primary: must be unique, is an index, is (likely) the physical index, can be only one per table.

unique: as it says. You can't have more than one row with a tuple of this value. Note that since a unique key can be over more than one column, this doesn't necessarily mean that each individual column in the index is unique, but that each combination of values across these columns is unique.

index: if it's not primary or unique, it doesn't constrain values inserted into the table, but it does allow them to be looked up more efficiently.

fulltext: a more specialized form of indexing that allows full text search. Think of it as (essentially) creating an "index" for each "word" in the specified column.

You need to know at least basics of Objective-C to develop for iPhone. However, it is possible to use C++ classes.

Personally I see an interface like a template. If a interface contains the definition for the methods foo() and bar(), then you know every class which uses this interface has the methods foo() and bar().

int(limit) returns the value converted into an integer, and doesn't change it in place as you call the function (which is what you are expecting it to).

Do this instead:

limit = int(limit)

Or when definiting limit:

if 'limit' in user_data :
    limit = int(user_data['limit'])

Device Pixel Ratio == CSS Pixel Ratio

In the world of web development, the device pixel ratio (also called CSS Pixel Ratio) is what determines how a device's screen resolution is interpreted by the CSS.

A browser's CSS calculates a device's logical (or interpreted) resolution by the formula:

For example:

Apple iPhone 6s

• Actual Resolution: 750 x 1334
• CSS Pixel Ratio: 2
• Logical Resolution:

When viewing a web page, the CSS will think the device has a 375x667 resolution screen and Media Queries will respond as if the screen is 375x667. But the rendered elements on the screen will be twice as sharp as an actual 375x667 screen because there are twice as many physical pixels in the physical screen.

Some other examples:

Samsung Galaxy S4

• Actual Resolution: 1080 x 1920
• CSS Pixel Ratio: 3
• Logical Resolution:

iPhone 5s

• Actual Resolution: 640 x 1136
• CSS Pixel Ratio: 2
• Logical Resolution:

Why does the Device Pixel Ratio exist?

The reason that CSS pixel ratio was created is because as phones screens get higher resolutions, if every device still had a CSS pixel ratio of 1 then webpages would render too small to see.

A typical full screen desktop monitor is a roughly 24" at 1920x1080 resolution. Imagine if that monitor was shrunk down to about 5" but had the same resolution. Viewing things on the screen would be impossible because they would be so small. But manufactures are coming out with 1920x1080 resolution phone screens consistently now.

So the device pixel ratio was invented by phone makers so that they could continue to push the resolution, sharpness and quality of phone screens, without making elements on the screen too small to see or read.

Here is a tool that also tells you your current device's pixel density:

I apologize if I am missing the point here, but I would like to recommend a different approach:

I think it's better to return raw data from your server side application and bind it to a template on the client side. This makes for more nimble requests since you're only returning json from your server.

To me it doesn't seem like it makes sense to use Angular if all you're doing is fetching html from the server and injecting it "as is" into the DOM.

I know Angular 1.x has an html binding, but I have not seen a counterpart in Angular 2.0 yet. They might add it later though. Anyway, I would still consider a data api for your Angular 2.0 app.

I have a few samples here with some simple data binding if you are interested: http://www.syntaxsuccess.com/viewarticle/angular-2.0-examples

In the case of the well voted solution posted by @Bikesh M Annur (here) doesn't work to you, try using:

<TextView
...
android:background="?android:attr/selectableItemBackgroundBorderless"
android:clickable="true" />

<ImageView
...
android:background="?android:attr/selectableItemBackgroundBorderless"
android:clickable="true" />

Also, when using android:clickable="true" add android:focusable="true" because:

"A widget that is declared to be clickable but not declared to be focusable is not accessible via the keyboard."

There are many ways.

<!-- Probably the most common: -->
<div style="text-align: center;"><a href="...">Link</a></div>

<!-- Getting crafty... -->
<a href="..." style="display: block; text-align: center;">Link</a></div>

There are probably other ways too, but these three are probably the most common.

Using changeit for the password is important too.

This command finally worked for me(with jetty):

 keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass changeit -validity 360 -keysize 2048

Now that works for me...

$(document).ready(function(){

    $(window).resize(function(e){
        console.log(e);                   
    });

    $(window).scroll(function (event) {
        var sc = $(window).scrollTop();
        console.log(sc);
    });

})

it works well... and then you can use JQuery/TweenMax to track elements and control them.

Here is a really simple and quick way to deal with this problem IF you have a local repo with all the branches and commits you need, and if you're OK with creating a new repo (or deleting the server's repo and making a new one in it's place):

1. Create a new empty repo on the server (or delete the old repo and create a new one in its place)
2. Change the remote URL of your local copy to point to the remote URL of the new repo.
3. Push all branches from your local repo to the new server repo.

This preserves all the commit history and branches that you had in your local repo.

If you have collaborators on the repo, then I think in many cases all your collaborators have to do is change the remote URL of their local repo as well, and optionally push any commits they have that the server doesn't have.

This solution worked for me when I ran into this same problem. I had one collaborator. After I pushed my local repo to the new remote repo, he simply changed his local repo to point to the remote repo URL and everything worked fine.

Faced same kind of problem and now clearly understood how both will works.Hope this reference link will be helpful...

Async

When you add the async attribute to your script tag, the fol­low­ing will happen.

<script src="myfile1.js" async></script>
<script src="myfile2.js" async></script>

1. Make par­al­lel requests to fetch the files.
2. Con­tinue pars­ing the doc­u­ment as if it was never interrupted.
3. Exe­cute the indi­vid­ual scripts the moment the files are downloaded.

Defer

Defer is very sim­i­lar to async with one major dif­fer­er­ence. Here’s what hap­pens when a browser encoun­ters a script with the defer attribute.

<script src="myfile1.js" defer></script>
<script src="myfile2.js" defer></script>

1. Make par­al­lel requests to fetch the indi­vid­ual files.
2. Con­tinue pars­ing the doc­u­ment as if it was never interrupted.
3. Fin­ish pars­ing the doc­u­ment even if the script files have downloaded.
4. Exe­cute each script in the order they were encoun­tered in the document.

Reference :Difference between Async and Defer

Clearly there are lots of scenarios, however, I had same domain for document and iframe and I was able to tack this on to the end of my iframe content:

var parentContainer = parent.document.querySelector("iframe[src*=\"" + window.location.pathname + "\"]");
parentContainer.style.height = document.body.scrollHeight + 50 + 'px';

This 'finds' the parent container and then sets the length adding on a fudge factor of 50 pixels to remove the scroll bar.

There is nothing there to 'observe' the document height changing, this I did not need for my use case. In my answer I do bring a means of referencing the parent container without using ids baked into the parent/iframe content.

It is possible and Spring MVC 3 does it, but I didn't take the time to see exactly how.

The matching of method parameter names to URI Template variable names can only be done if your code is compiled with debugging enabled. If you do have not debugging enabled, you must specify the name of the URI Template variable name in the @PathVariable annotation in order to bind the resolved value of the variable name to a method parameter. For example:

Taken from the spring documentation

Mutable means that it can change/mutate. Immutable the opposite.

Some Python data types are mutable, others not.

Let's find what are the types that fit in each category and see some examples.

Mutable

In Python there are various mutable types:

• lists

• dict

• set

Let's see the following example for lists.

list = [1, 2, 3, 4, 5]

If I do the following to change the first element

list[0] = '!'
#['!', '2', '3', '4', '5']

It works just fine, as lists are mutable.

If we consider that list, that was changed, and assign a variable to it

y = list

And if we change an element from the list such as

list[0] = 'Hello'
#['Hello', '2', '3', '4', '5']

And if one prints y it will give

['Hello', '2', '3', '4', '5']

As both list and y are referring to the same list, and we have changed the list.

Immutable

In some programming languages one can define a constant such as the following

const a = 10

And if one calls, it would give an error

a = 20

However, that doesn't exist in Python.

In Python, however, there are various immutable types:

• None

• bool

• int

• float

• str

• tuple

Let's see the following example for strings.

Taking the string a

a = 'abcd'

We can get the first element with

a[0]
#'a'

If one tries to assign a new value to the element in the first position

a[0] = '!'

It will give an error

'str' object does not support item assignment

When one says += to a string, such as

a += 'e'
#'abcde'

It doesn't give an error, because it is pointing a to a different string.

It would be the same as the following

a = a + 'f'

And not changing the string.

Some Pros and Cons of being immutable

• The space in memory is known from the start. It would not require extra space.

• Usually, it makes things more efficiently. Finding, for example, the len() of a string is much faster, as it is part of the string object.

        using (TextReader reader = new StringReader(xmlString))
        {
            return (T) serializer.Deserialize(reader);
        }
    }

I find this type of approach works for me:

Product     ProductDetail        Country
=========   ==================   =========
ProductId   ProductDetailId      CountryId
- etc -     ProductId            CountryName
            CountryId            Language
            ProductName          - etc -
            ProductDescription
            - etc -

The ProductDetail table holds all the translations (for product name, description etc..) in the languages you want to support. Depending on your app's requirements, you may wish to break the Country table down to use regional languages too.

Something that really needs to be pointed out is that there are really two aspects to this question - the theoretical aspect and the implementations aspect.

First, let's look at the theoretical aspect. You need to understand what a process is conceptually to understand the difference between a process and a thread and what's shared between them.

We have the following from section 2.2.2 The Classical Thread Model in Modern Operating Systems 3e by Tanenbaum:

The process model is based on two independent concepts: resource grouping and execution. Sometimes it is use­ful to separate them; this is where threads come in....

He continues:

One way of looking at a process is that it is a way to group related resources together. A process has an address space containing program text and data, as well as other resources. These resource may include open files, child processes, pending alarms, signal handlers, accounting information, and more. By putting them together in the form of a process, they can be managed more easily. The other concept a process has is a thread of execution, usually shortened to just thread. The thread has a program counter that keeps track of which instruc­tion to execute next. It has registers, which hold its current working variables. It has a stack, which contains the execution history, with one frame for each proce­dure called but not yet returned from. Although a thread must execute in some process, the thread and its process are different concepts and can be treated sepa­rately. Processes are used to group resources together; threads are the entities scheduled for execution on the CPU.

Further down he provides the following table:

Per process items             | Per thread items
------------------------------|-----------------
Address space                 | Program counter
Global variables              | Registers
Open files                    | Stack
Child processes               | State
Pending alarms                |
Signals and signal handlers   |
Accounting information        |

The above is what you need for threads to work. As others have pointed out, things like segments are OS dependant implementation details.

PDFBox is the best library I've found for this purpose, it's comprehensive and really quite easy to use if you're just doing basic text extraction. Examples can be found here.

It explains it on the page, but one thing to watch out for is that the start and end indexes when using setStartPage() and setEndPage() are both inclusive. I skipped over that explanation first time round and then it took me a while to realise why I was getting more than one page back with each call!

Itext is another alternative that also works with C#, though I've personally never used it. It's more low level than PDFBox, so less suited to the job if all you need is basic text extraction.

The code you posted is wrong, it should throw an Exception if is catching a specific exception in order to handler IOException but throwing not catched exceptions.

Something like:

public void method() throws Exception{
   try{
           BufferedReader br = new BufferedReader(new FileReader("file.txt"));
   }catch(IOException e){
           System.out.println(e.getMessage());
   }
}

or

public void method(){
   try{
           BufferedReader br = new BufferedReader(new FileReader("file.txt"));
   }catch(IOException e){
           System.out.println("Catching IOException");
           System.out.println(e.getMessage());
   }catch(Exception e){
           System.out.println("Catching any other Exceptions like NullPontException, FileNotFoundExceptioon, etc.");
           System.out.println(e.getMessage());
   }

}

Look at the filter function.

If you just need a 1-pole low-pass filter, it's

xfilt = filter(a, [1 a-1], x);

where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant.

Here's the corresponding high-pass filter:

xfilt = filter([1-a a-1],[1 a-1], x);

If you need to design a filter, and have a license for the Signal Processing Toolbox, there's a bunch of functions, look at fvtool and fdatool.

Once you have the source trees, e.g.

diff -ENwbur repos1/ repos2/ 

Even better

diff -ENwbur repos1/ repos2/  | kompare -o -

and have a crack at it in a good gui tool :)

• -Ewb ignore the bulk of whitespace changes
• -N detect new files
• -u unified
• -r recurse

mvn clean install -Dmaven.test.skip=true

worked for me since the -Dskip did not work anymore.

HTML:

First, we will need to add a class to your text container so that we can access and style it accordingly.

<div class="col-xs-5 textContainer">
     <h3 class="text-left">Link up with other gamers all over the world who share the same tastes in games.</h3>
</div>

CSS:

Next, we will apply the following styles to align it vertically, according to the size of the image div next to it.

.textContainer { 
    height: 345px; 
    line-height: 340px;
}

.textContainer h3 {
    vertical-align: middle;
    display: inline-block;
}

All Done! Adjust the line-height and height on the styles above if you believe that it is still slightly out of align.

WORKING EXAMPLE

In Entity Framework Core 2.1 we can use Query Types as Yuriy N suggested.

A more detailed article on how to use them can be found here

The most straight forward approach according to the article's examples would be:

1.We have for example the following entity Models to manage publications

public class Magazine
{
  public int MagazineId { get; set; }
  public string Name { get; set; }
  public string Publisher { get; set; }
  public List<Article> Articles { get; set; }
}

public class Article
{
  public int ArticleId { get; set; }
  public string Title { get; set; }
  public int MagazineId { get; set; }
  public DateTime PublishDate { get;  set; }
  public Author Author { get; set; }
  public int AuthorId { get; set; }
}
public class Author
{
  public int AuthorId { get; set; }
  public string Name { get; set; }
  public List<Article> Articles { get; set; }
}

2.We have a view called AuthorArticleCounts, defined to return the name and number of articles an author has written

SELECT
  a.AuthorName,
  Count(r.ArticleId) as ArticleCount
from Authors a
  JOIN Articles r on r.AuthorId = a.AuthorId
GROUP BY a.AuthorName

3.We go and create a model to be used for the View

public class AuthorArticleCount
{
  public string AuthorName { get; private set; }
  public int ArticleCount { get; private set; }
}

4.We create after that a DbQuery property in my DbContext to consume the view results inside the Model

public DbQuery<AuthorArticleCount> AuthorArticleCounts{get;set;}

4.1. You might need to override OnModelCreating() and set up the View especially if you have different view name than your Class.

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Query<AuthorArticleCount>().ToView("AuthorArticleCount");
}

5.Finally we can easily get the results of the View like this.

var results=_context.AuthorArticleCounts.ToList();

UPDATE According to ssougnez's comment

It's worth noting that DbQuery won't be/is not supported anymore in EF Core 3.0. See here

Please follow the below steps File > Settings > Build,Execution,Deployment > Instant Run > Un-check (Enable Instant Run to hot swap code)

this is working for me

thanks

Seaborn's barplot returns an axis-object (not a figure). This means you can do the following:

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
ax = sns.barplot(x = 'val', y = 'cat', 
              data = fake, 
              color = 'black')
ax.set(xlabel='common xlabel', ylabel='common ylabel')
plt.show()

There is a slight difference between the top answers, namely SUM(case when kind = 1 then 1 else 0 end) and SUM(kind=1).

When all values in column kind happen to be NULL, the result of SUM(case when kind = 1 then 1 else 0 end) is 0, whereas the result of SUM(kind=1) is NULL.

An example (http://sqlfiddle.com/#!9/b23807/2):

Schema:

CREATE TABLE Table1
(`first_col` int, `second_col` int)
;

INSERT INTO Table1
    (`first_col`, `second_col`)
VALUES
       (1, NULL),
       (1, NULL),
       (NULL, NULL)
;

Query results:

SELECT SUM(first_col=1) FROM Table1;
-- Result: 2
SELECT SUM(first_col=2) FROM Table1;
-- Result: 0
SELECT SUM(second_col=1) FROM Table1;
-- Result: NULL
SELECT SUM(CASE WHEN second_col=1 THEN 1 ELSE 0 END) FROM Table1;
-- Result: 0

I tried to require a development branch from a different repository and not the latest version and I had the same issue and non of the above worked for me :(

after a while I saw in the documentation that in cases of dev branch you need to require with a 'dev-' prefix to the version and the following worked perfectly.

composer require [vendorName]/[packageName]:dev-[gitBranchName]

You can do it like this:

angular.element('#modal').modal('hide');

**The best is to use try except block to get rid of EOF **

try:
    width = input()
    height = input()
    def rectanglePerimeter(width, height):
       return ((width + height)*2)
    print(rectanglePerimeter(width, height))
except EOFError as e:
    print(end="")

Firstly, use an IMG tag in your HTML to embed an SVG graphic. I used Adobe Illustrator to make the graphic.

<img id="facebook-logo" class="svg social-link" src="/images/logo-facebook.svg"/>

This is just like how you'd embed a normal image. Note that you need to set the IMG to have a class of svg. The 'social-link' class is just for examples sake. The ID is not required, but is useful.

Then use this jQuery code (in a separate file or inline in the HEAD).

    /**
     * Replace all SVG images with inline SVG
     */
        jQuery('img.svg').each(function(){
            var $img = jQuery(this);
            var imgID = $img.attr('id');
            var imgClass = $img.attr('class');
            var imgURL = $img.attr('src');

            jQuery.get(imgURL, function(data) {
                // Get the SVG tag, ignore the rest
                var $svg = jQuery(data).find('svg');

                // Add replaced image's ID to the new SVG
                if(typeof imgID !== 'undefined') {
                    $svg = $svg.attr('id', imgID);
                }
                // Add replaced image's classes to the new SVG
                if(typeof imgClass !== 'undefined') {
                    $svg = $svg.attr('class', imgClass+' replaced-svg');
                }

                // Remove any invalid XML tags as per http://validator.w3.org
                $svg = $svg.removeAttr('xmlns:a');

                // Replace image with new SVG
                $img.replaceWith($svg);

            }, 'xml');

        });

What the above code does is look for all IMG's with the class 'svg' and replace it with the inline SVG from the linked file. The massive advantage is that it allows you to use CSS to change the color of the SVG now, like so:

svg:hover path {
    fill: red;
}

The jQuery code I wrote also ports across the original images ID and classes. So this CSS works too:

#facebook-logo:hover path {
    fill: red;
}

Or:

.social-link:hover path {
    fill: red;
}

You can see an example of it working here: http://labs.funkhausdesign.com/examples/img-svg/img-to-svg.html

We have a more complicated version that includes caching here: https://github.com/funkhaus/style-guide/blob/master/template/js/site.js#L32-L90

Putting a whole array into one localStorage entry is very inefficient: the whole thing needs to be re-encoded every time you add something to the array or change one entry.

An alternative is to use http://rhaboo.org which stores any JS object, however deeply nested, using a separate localStorage entry for each terminal value. Arrays are restored much more faithfully, including non-numeric properties and various types of sparseness, object prototypes/constructors are restored in standard cases and the API is ludicrously simple:

var store = Rhaboo.persistent('Some name');
store.write('count', store.count ? store.count+1 : 1);

store.write('somethingfancy', {
  one: ['man', 'went'],
  2: 'mow',
  went: [  2, { mow: ['a', 'meadow' ] }, {}  ]
});  
store.somethingfancy.went[1].mow.write(1, 'lawn');

BTW, I wrote it.

Way to instantly get first value:

$neededObject = array_reduce(
    $arrayOfObjects,
    function ($result, $item) use ($searchedValue) {
        return $item->id == $searchedValue ? $item : $result;
    }
);

EDIT: After your comments, I understand that you want to pass variable through your form.

You can do this using hidden field:

<input type='hidden' name='var' value='<?php echo "$var";?>'/> 

In PHP action File:

<?php 
   if(isset($_POST['var'])) $var=$_POST['var'];
?>

Or using sessions: In your first page:

 $_SESSION['var']=$var;

start_session(); should be placed at the beginning of your php page.

In PHP action File:

if(isset($_SESSION['var'])) $var=$_SESSION['var'];

First Answer:

You can also use $GLOBALS :

if (isset($_POST['save_exit']))
{

   echo $GLOBALS['var']; 

}

Check this documentation for more informations.

You may need to repair your mdf file first using some tools. There are lot of tool available in the market. There is tool called SQL Database Recovery Tool Repairs which is very useful to repair the mdf files.

The issue might me because of corrupted transaction logs, you may use tool SQL Database Recovery Tool Repairs to repair your corrupted mdf file.

You can use pure Javascript to achieve this:

var test = true;
if (typeof test === 'boolean')
   console.log('test is a boolean!');

Should it have anything to do with "opacity" of the form / its background ? Did you try opacity = 0

Also see if this CP article helps:

You can also use the combination of find and awk commands to print the directory tree. For details, please refer to "How to print a multilevel tree directory structure using the linux find and awk combined commands"

find . -type d | awk -F'/' '{ 
depth=3;
offset=2;
str="|  ";
path="";
if(NF >= 2 && NF < depth + offset) {
    while(offset < NF) {
        path = path "|  ";
        offset ++;
    }
    print path "|-- "$NF;
}}'

try this:

echo ${array[@]} | awk 'BEGIN{RS=" ";} {print $1}' | sort

Output will be:

3
5
a
b
c
f

Problem solved.

When the WSDL is available, it is just two steps you need to follow to invoke that web service.

Step 1: Generate the client side source from a WSDL2Java tool

Step 2: Invoke the operation using:

YourService service = new YourServiceLocator();
Stub stub = service.getYourStub();
stub.operation();

If you look further, you will notice that the Stub class is used to invoke the service deployed at the remote location as a web service. When invoking that, your client actually generates the SOAP request and communicates. Similarly the web service sends the response as a SOAP. With the help of a tool like Wireshark, you can view the SOAP messages exchanged.

However since you have requested more explanation on the basics, I recommend you to refer here and write a web service with it's client to learn it further.

.push() will add elements to the end of an array.

Use .unshift() if need to add some element to the beginning of array i.e:

items.unshift({'id':5});

Demo:

items = [{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}];_x000D_
items.unshift({'id': 0});_x000D_
console.log(items);

And use .splice() in case you want to add object at a particular index i.e:

items.splice(2, 0, {'id':5});
           // ^ Given object will be placed at index 2...

Demo:

items = [{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}];_x000D_
items.splice(2, 0, {'id': 2.5});_x000D_
console.log(items);

After making changes to the pg_hba.conf or postgresql.conf files, the cluster needs to be reloaded to pick up the changes.

From the command line: pg_ctl reload

From within a db (as superuser): select pg_reload_conf();

From PGAdmin: right-click db name, select "Reload Configuration"

Note: the reload is not sufficient for changes like enabling archiving, changing shared_buffers, etc -- those require a cluster restart.

What is it?

When you create an object in a .Net framework application, you don't need to think about how the data is stored in memory. Because the .Net Framework takes care of that for you. However, if you want to store the contents of an object to a file, send an object to another process or transmit it across the network, you do have to think about how the object is represented because you will need to convert to a different format. This conversion is called SERIALIZATION.

Uses for Serialization

Serialization allows the developer to save the state of an object and recreate it as needed, providing storage of objects as well as data exchange. Through serialization, a developer can perform actions like sending the object to a remote application by means of a Web Service, passing an object from one domain to another, passing an object through a firewall as an XML string, or maintaining security or user-specific information across applications.

Apply SerializableAttribute to a type to indicate that instances of this type can be serialized. Apply the SerializableAttribute even if the class also implements the ISerializable interface to control the serialization process.

All the public and private fields in a type that are marked by the SerializableAttribute are serialized by default, unless the type implements the ISerializable interface to override the serialization process. The default serialization process excludes fields that are marked with NonSerializedAttribute. If a field of a serializable type contains a pointer, a handle, or some other data structure that is specific to a particular environment, and cannot be meaningfully reconstituted in a different environment, then you might want to apply NonSerializedAttribute to that field.

See MSDN for more details.

Edit 1

Any reason to not mark something as serializable

When transferring or saving data, you need to send or save only the required data. So there will be less transfer delays and storage issues. So you can opt out unnecessary chunk of data when serializing.

: is the delimiter of the slice syntax to 'slice out' sub-parts in sequences , [start:end]

[1:5] is equivalent to "from 1 to 5" (5 not included)
[1:] is equivalent to "1 to end"
[len(a):] is equivalent to "from length of a to end"

Watch https://youtu.be/tKTZoB2Vjuk?t=41m40s at around 40:00 he starts explaining that.

Works with tuples and strings, too.

I found another situation in which this problem may arise (despite following the steps listed by other users above) and that's when the username of the user you're logged in as has an '_' on it. The path it will try to use to find the temp directory is whatever is set in %TEMP%. I managed to work around it by:

1. Launch cmd.exe in Administrator mode
2. SET TEMP = C:\TEMP
3. Run the installer from that command window

Installed successfully that way.

You don't need to specify the module path per se. CMake ships with its own set of built-in find_package scripts, and their location is in the default CMAKE_MODULE_PATH.

The more normal use case for dependent projects that have been CMakeified would be to use CMake's external_project command and then include the Use[Project].cmake file from the subproject. If you just need the Find[Project].cmake script, copy it out of the subproject and into your own project's source code, and then you won't need to augment the CMAKE_MODULE_PATH in order to find the subproject at the system level.

It seems like you are essentially looking into computing the z-score or standard score of your data, which is calculated through the formula: z = (x-mean(x))/std(x)

This should work:

%% Original data (Normal with mean 1 and standard deviation 2)
x = 1 + 2*randn(100,1);
mean(x)
var(x)
std(x)

%% Normalized data with mean 0 and variance 1
z = (x-mean(x))/std(x);
mean(z)
var(z)
std(z)

my solution was - just remove '*' character from the expression ^__^

Yep, Oracle has temporary tables. Here is a link to an AskTom article describing them and here is the official oracle CREATE TABLE documentation.

However, in Oracle, only the data in a temporary table is temporary. The table is a regular object visible to other sessions. It is a bad practice to frequently create and drop temporary tables in Oracle.

CREATE GLOBAL TEMPORARY TABLE today_sales(order_id NUMBER)
ON COMMIT PRESERVE ROWS;

Oracle 18c added private temporary tables, which are single-session in-memory objects. See the documentation for more details. Private temporary tables can be dynamically created and dropped.

CREATE PRIVATE TEMPORARY TABLE ora$ptt_today_sales AS
SELECT * FROM orders WHERE order_date = SYSDATE;

Temporary tables can be useful but they are commonly abused in Oracle. They can often be avoided by combining multiple steps into a single SQL statement using inline views.

As seen in https://github.com/atom/electron/issues/254 the problem is caused because of this code:

if ( typeof module === "object" && typeof module.exports === "object" ) {
  // set jQuery in `module`
} else {
  // set jQuery in `window`
}

The jQuery code "sees" that its running in a CommonJS environment and ignores window.

The solution is really easy, instead of loading jQuery through <script src="...">, you should load like this:

<script>window.$ = window.jQuery = require('./path/to/jquery');</script>

Note: the dot before the path is required, since it indicates that it's the current directory. Also, remember to load jQuery before loading any other plugin that depends on it.

As the error code says, "no alternative certificate subject name matches target host name" - so there is an issue with the SSL certificate.

The certificate should include SAN, and only SAN will be used. Some browsers ignore the deprecated Common Name.

RFC 2818 clearly states "If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead."

Maybe it will help someone, but sometimes Name tag might be missing for a reference and it leads that assembly cannot be found when building with MSBuild. Make sure that Name tag is available for particular reference csproj file, for example,

    <ProjectReference Include="..\MyDependency1.csproj">
      <Project>{9A2D95B3-63B0-4D53-91F1-5EFB99B22FE8}</Project>
      <Name>MyDependency1</Name>
    </ProjectReference>

$timestamp = strtotime($row['DATETIMEAPP']);

gives you timestamp, which then you can use date to format:

$date = date('d-m-Y', $timestamp);
$time = date('Gi.s', $timestamp);

Alternatively

list($date, $time) = explode('|', date('d-m-Y|Gi.s', $timestamp));

As a good practice I think it is a good idea to test if a popup was blocked and take action in case. You need to know that window.open has a return value, and that value may be null if the action failed. For example, in the following code:

function pop(url,w,h) {
    n=window.open(url,'_blank','toolbar=0,location=0,directories=0,status=1,menubar=0,titlebar=0,scrollbars=1,resizable=1,width='+w+',height='+h);
    if(n==null) {
        return true;
    }
    return false;
}

if the popup is blocked, window.open will return null. So the function will return false.

As an example, imagine calling this function directly from any link with target="_blank": if the popup is successfully opened, returning false will block the link action, else if the popup is blocked, returning true will let the default behavior (open new _blank window) and go on.

<a href="http://whatever.com" target="_blank" onclick='return pop("http://whatever.com",300,200);' >

This way you will have a popup if it works, and a _blank window if not.

If the popup does not open, you can:

• open a blank window like in the example and go on
• open a fake popup (an iframe inside the page)
• inform the user ("please allow popups for this site")
• open a blank window and then inform the user etc..

The array creation syntaxes in C# that are expressions are:

new int[3]
new int[3] { 10, 20, 30 }
new int[] { 10, 20, 30 }
new[] { 10, 20, 30 }

In the first one, the size may be any non-negative integral value and the array elements are initialized to the default values.

In the second one, the size must be a constant and the number of elements given must match. There must be an implicit conversion from the given elements to the given array element type.

In the third one, the elements must be implicitly convertible to the element type, and the size is determined from the number of elements given.

In the fourth one the type of the array element is inferred by computing the best type, if there is one, of all the given elements that have types. All the elements must be implicitly convertible to that type. The size is determined from the number of elements given. This syntax was introduced in C# 3.0.

There is also a syntax which may only be used in a declaration:

int[] x = { 10, 20, 30 };

The elements must be implicitly convertible to the element type. The size is determined from the number of elements given.

there isn't an all-in-one guide

I refer you to C# 4.0 specification, section 7.6.10.4 "Array Creation Expressions".

The sleep man page says it is declared in <unistd.h>.

Synopsis:

#include <unistd.h>

unsigned int sleep(unsigned int seconds);

CTRL-C generally sends a SIGINT signal to the process so you can simply do:

kill -INT <processID>

from the command line (or a script), to affect the specific processID.

I say "generally" because, as with most of UNIX, this is near infinitely configurable. If you execute stty -a, you can see which key sequence is tied to the intr signal. This will probably be CTRL-C but that key sequence may be mapped to something else entirely.

The following script shows this in action (albeit with TERM rather than INT since sleep doesn't react to INT in my environment):

#!/usr/bin/env bash

sleep 3600 &
pid=$!
sleep 5

echo ===
echo PID is $pid, before kill:
ps -ef | grep -E "PPID|$pid" | sed 's/^/   /'
echo ===

( kill -TERM $pid ) 2>&1
sleep 5

echo ===
echo PID is $pid, after kill:
ps -ef | grep -E "PPID|$pid" | sed 's/^/   /'
echo ===

It basically starts an hour-log sleep process and grabs its process ID. It then outputs the relevant process details before killing the process.

After a small wait, it then checks the process table to see if the process has gone. As you can see from the output of the script, it is indeed gone:

===
PID is 28380, before kill:
   UID   PID     PPID    TTY     STIME      COMMAND
   pax   28380   24652   tty42   09:26:49   /bin/sleep
===
./qq.sh: line 12: 28380 Terminated              sleep 3600
===
PID is 28380, after kill:
   UID   PID     PPID    TTY     STIME      COMMAND
===

This goes to you model:

public function count_news_by_category($cat)
{
    return $this->db
        ->where('category', $cat)
        ->where('is_enabled', 1)
        ->count_all_results('news');
}

It'a an example from my current project.

According to benchmarking this query works faster than if you do the following:

$this->db->select('*')->from('news')->where(...); 
$q = $this->db->get(); 
return $q->num_rows();

None of the other answers worked for me. Note that SQL Server will give different results if you pass in a hard-coded string versus feed it from a column in your result set. Below is the magic that worked for me to give a perfect match between SQL Server and MySql

select LOWER(CONVERT(VARCHAR(32), HashBytes('MD5', CONVERT(varchar, EmailAddress)), 2)) from ...

I've gotten same problem. The servers logs showed:

DEBUG: <-- origin: null

I've investigated that and it occurred that this is not populated when I've been calling from file from local drive. When I've copied file to the server and used it from server - the request worked perfectly fine

Using ANSI SQL-92 CASE Statements, you could do something like this (derived table plus case):

 SELECT jobId, jobName, SUM(Priority1)
 AS Priority1, SUM(Priority2) AS
 Priority2, SUM(Priority3) AS
 Priority3, SUM(Priority4) AS
 Priority4,  SUM(Priority5) AS
 Priority5 FROM (
     SELECT jobId, jobName,
     CASE WHEN Priority = 1 THEN 1 ELSE 0 END AS Priority1,
     CASE WHEN Priority = 2 THEN 1 ELSE 0 END AS Priority2,
     CASE WHEN Priority = 3 THEN 1 ELSE 0 END AS Priority3,
     CASE WHEN Priority = 4 THEN 1 ELSE 0 END AS Priority4,
     CASE WHEN Priority = 5 THEN 1 ELSE 0 END AS Priority5
     FROM TableName


)

You can use stepi or nexti (which can be abbreviated to si or ni) to step through your machine code.

For the me issue was that I had 2 other Android Emulators running. Once I closed those, I was able to start the new one.

Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.

This approach will work ONLY when the total duration is less than 24 hours:

var now  = "04/09/2013 15:00:00";
var then = "04/09/2013 14:20:30";

moment.utc(moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"))).format("HH:mm:ss")

// outputs: "00:39:30"

If you have 24 hours or more, the hours will reset to zero with the above approach, so it is not ideal.

If you want to get a valid response for durations of 24 hours or greater, then you'll have to do something like this instead:

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = Math.floor(d.asHours()) + moment.utc(ms).format(":mm:ss");

// outputs: "48:39:30"

Note that I'm using the utc time as a shortcut. You could pull out d.minutes() and d.seconds() separately, but you would also have to zeropad them.

This is necessary because the ability to format a duration objection is not currently in moment.js. It has been requested here. However, there is a third-party plugin called moment-duration-format that is specifically for this purpose:

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = d.format("hh:mm:ss");

// outputs: "48:39:30"

I don't think there is one answer here, so I'll add my experience. I seen this same error along with random httpd segfaults. This was a cPanel server. The symptom in question was apache would randomly reset the connection (No data received in chrome, or connection was reset in firefox). These were seemingly random -- most of the time it worked, sometimes it did not.

When I arrived on the scene output buffering was OFF. By reading this thread, that hinted at output buffering, I turned it on (=4096) to see what would happen. At this point, they all started showing the errors. This was good being that the error was now repeatable.

I went through and started disabling extensions. Among them, eaccellerator, pdo, ioncube loader, and plenty that looked suspicion, but none helped.

I finally found the naughty PHP extension as "homeloader.so", which appears to be some kind of cPanel-easy-installer module. After removal, I haven't experienced any other issues.

On that note, it appears this is a generic error message so your milage will vary with all of these answers, best course of action you can take:

• Make the error repeatable (what conditions?) every time
• Find the common factor
• Selectively disable any PHP modules, options, etc (or, if you're in a rush, disable them all to see if it helps, then selectively re-enable them until it breaks again)
• If this fails to help, many of these answers hint that it could be code releated. Again, the key is to make the error repeatable every request so you can narrow it down. If you suspect a piece of code is doing this, once again, after the error is repeatable, just remove code until the error stops. Once it stops, you know the last piece of code you removed was the culprit.

Failing all of the above, you could also try things like:

• Upgrading or recompiling PHP. Hope whatever bug is causing your issue is fixed.
• Move your code to a different (testing) environment. If this fixes the issue, what changed? php.ini options? PHP version? etc...

Good luck.

I solved this problem like this.

1. setImage to UIImageView (with UIViewContentModeScaleAspectFit)
2. get imageSize (CGSize imageSize = imageView.image.size)
3. UIImageView resize. [imageView sizeThatFits:imageSize]
4. move position where you want.

I wanted to put UIView on the top center of UICollectionViewCell. so, I used this function.

- (void)setImageToCenter:(UIImageView *)imageView
{
    CGSize imageSize = imageView.image.size;
    [imageView sizeThatFits:imageSize];
    CGPoint imageViewCenter = imageView.center;
     imageViewCenter.x = CGRectGetMidX(self.contentView.frame);
    [imageView setCenter:imageViewCenter];
}

It works for me.

I had the same problem in various different situations, and the solutions i have found work in some but dont work in others so here is a combine solution that works in most situations i have found:

public static void showVirtualKeyboard(Context context, final View view) {
    if (context != null) {
        final InputMethodManager imm =  (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
        view.clearFocus();

        if(view.isShown()) {
            imm.showSoftInput(view, 0);
            view.requestFocus();
        } else {
            view.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
                @Override
                public void onViewAttachedToWindow(View v) {
                    view.post(new Runnable() {
                        @Override
                        public void run() {
                            view.requestFocus();
                            imm.showSoftInput(view, 0);
                        }
                    });

                    view.removeOnAttachStateChangeListener(this);
                }

                @Override

                    view.removeOnAttachStateChangeListener(this);

        }
    }
}

Use div instead of span, or add display: block; to your css style for the span tag.

In addition to the answer from @WoLpH.

When using the LIKE keyword you also have the ability to limit which direction the string matches. For example:

If you were looking for a string that starts with your $needle:

... WHERE column LIKE '{$needle}%'

If you were looking for a string that ends with the $needle:

... WHERE column LIKE '%{$needle}'

This post helped me solve a similar problem with a PostgreSQL database link to Oracle using oracle_fdw.

I installed oracle_fdw but when I tried CREATE EXTENSION oracle_fdw; I got error could not load library libclntsh.so.11.1: cannot open shared object file: No such file or directory.

I checked $ORACLE_HOME, $PATH and $LD_LIBRARY_PATH.

It worked only AFTER I put Oracle Shared Library on Linux Shared Library

echo /opt/instantclient_11_2 > oracle.conf
ldconfig

We're not necessarily talking theoretical limits here, we're talking about real world limits of the 2GB max file size AND database schema.

• Is your db a single table or multiple?
• How many columns does each table have?
• What are the datatypes?

The schema is on even footing with the row count in determining how many rows you can have.

We have used Access MDBs to store exports of MS-SQL data for statistical analysis by some of our corporate users. In those cases we've exported our core table structure, typically four tables with 20 to 150 columns varying from a hundred bytes per row to upwards of 8000 bytes per row. In these cases, we would bump up against a few hundred thousand rows of data were permissible PER MDB that we would ship them.

So, I just don't think that this question has an answer in absence of your schema.

Two-way binding just means that:

1. When properties in the model get updated, so does the UI.
2. When UI elements get updated, the changes get propagated back to the model.

Backbone doesn't have a "baked-in" implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding automagically.

In Backbone, you can easily achieve #1 by binding a view's "render" method to its model's "change" event. To achieve #2, you need to also add a change listener to the input element, and call model.set in the handler.

Here's a Fiddle with two-way binding set up in Backbone.

In my case it worked perfectly

<img style="border-radius: 50%;height: 50px;width: 80px;"  src="<?php echo asset("storage/TeacherImages/{$teacher->profilePic}")?>">

this is used to display image from folder i hope this will help someone looking for this type of code

$(".field-group_name").each(function() {
        console.log($(this).text());
    });

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

you should try this

g++-4.4 -std=c++0x or g++-4.7 -std=c++0x

also you can reimplement protected member QWidget::closeEvent()

void YourWidgetWithXButton::closeEvent(QCloseEvent *event)
{
    // do what you need here
    // then call parent's procedure
    QWidget::closeEvent(event);
}

  var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["Jwt:Key"]));
  var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
  var claims = new[]
  {
      new Claim(JwtRegisteredClaimNames.Email, model.UserName),
      new Claim(JwtRegisteredClaimNames.NameId, model.Id.ToString()),
  };
  var token = new JwtSecurityToken(_config["Jwt:Issuer"],
      _config["Jwt:Issuer"],
      claims,
      expires: DateTime.Now.AddMinutes(30),
      signingCredentials: creds);

Then extract content

 var handler = new JwtSecurityTokenHandler();
 string authHeader = Request.Headers["Authorization"];
 authHeader = authHeader.Replace("Bearer ", "");
 var jsonToken = handler.ReadToken(authHeader);
 var tokenS = handler.ReadToken(authHeader) as JwtSecurityToken;
 var id = tokenS.Claims.First(claim => claim.Type == "nameid").Value;

The Distinct() guarantees that there are no duplicates pair (CategoryId, CategoryName).

- exactly that

I assume another error somewhere. Case sensitivity? Mutable classes? Non-comparable fields?

I've only seen the parsing error when the android version on the device was lower than the version the app was compiled for. For example if the app is compiled for android OS v2.2 and your device only has android OS v2.1 you'd get a parse error when you try to install the app.

you can do this by

date("F j, Y", time() - 60 * 60 * 24);

or by

date("F j, Y", strtotime("yesterday"));

public class Data<T> extends JsonDeserializer implements ContextualDeserializer {
    private Class<T> cls;
    public JsonDeserializer createContextual(DeserializationContext ctx, BeanProperty prop) throws JsonMappingException {
        cls = (Class<T>) ctx.getContextualType().getRawClass();
        return this;
    }
    ...
 }

if I use the clear() member function. Can I be sure that the memory was released?

No, the clear() member function destroys every object contained in the vector, but it leaves the capacity of the vector unchanged. It affects the vector's size, but not the capacity.

If you want to change the capacity of a vector, you can use the clear-and-minimize idiom, i.e., create a (temporary) empty vector and then swap both vectors.

You can easily see how each approach affects capacity. Consider the following function template that calls the clear() member function on the passed vector:

template<typename T>
auto clear(std::vector<T>& vec) {
   vec.clear();
   return vec.capacity();
}

Now, consider the function template empty_swap() that swaps the passed vector with an empty one:

template<typename T>
auto empty_swap(std::vector<T>& vec) {
   std::vector<T>().swap(vec);
   return vec.capacity();
}

Both function templates return the capacity of the vector at the moment of returning, then:

std::vector<double> v(1000), u(1000);
std::cout << clear(v) << '\n';
std::cout << empty_swap(u) << '\n';

outputs:

1000
0

Your example worked for me with MongoDB 1.6.3 and 1.7.3. Example below was for 1.7.3. Are you using an older version of MongoDB?

connected to: 127.0.0.1
imported 3 objects
$ mongo
MongoDB shell version: 1.7.3
connecting to: test

> db.things.find()
{ "_id" : ObjectId("4d32a36ed63d057130c08fca"), "Name" : "Jane Doe", "Address" : "123 Main St", "City" : "Whereverville", "State" : "CA", "ZIP" : 90210 }
{ "_id" : ObjectId("4d32a36ed63d057130c08fcb"), "Name" : "John Doe", "Address" : "555 Broadway Ave", "City" : "New York", "State" : "NY", "ZIP" : 10010 }

If you just need to check if there are ANY elements in the array

if (empty($playerlist)) {
     // list is empty.
}

If you need to clean out empty values before checking (generally done to prevent explodeing weird strings):

foreach ($playerlist as $key => $value) {
    if (empty($value)) {
       unset($playerlist[$key]);
    }
}
if (empty($playerlist)) {
   //empty array
}

The error message outlines the solution. The line

doNothing().when(cmd).dnsCheck(HOST, any(InetAddressFactory.class))

uses one raw value and one matcher, when it's required to use either all raw values or all matchers. A correct version might read

doNothing().when(cmd).dnsCheck(eq(HOST), any(InetAddressFactory.class))

Try:

>>> t = ((1, 'a'),(2, 'b'))
>>> dict((y, x) for x, y in t)
{'a': 1, 'b': 2}

to display date and time, try this:

=Format(Now(), "dd/MM/yyyy hh:mm tt")

Adding to what @dardisco mentioned about mefa::rep.data.frame(), it's very flexible.

You can either repeat each row N times:

rep(df, each=N)

or repeat the entire dataframe N times (think: like when you recycle a vectorized argument)

rep(df, times=N)

Two thumbs up for mefa! I had never heard of it until now and I had to write manual code to do this.

I'm going to answer this myself.

I've determined that there is a difference. "git fetch --tags" might bring in all the tags, but it doesn't bring in any new commits!

Turns out one has to do this to be totally "up to date", i.e. replicated a "git pull" without the merge:

$ git fetch --tags
$ git fetch

This is a shame, because it's twice as slow. If only "git fetch" had an option to do what it normally does and bring in all the tags.

For anyone facing this issue and ending up on this post...the issue is still open - https://github.com/moby/moby/issues/11185

SELECT chargeId, chargeType, MAX(serviceMonth) AS serviceMonth 
FROM invoice
GROUP BY chargeId, chargeType

Or you could try to avoid some temps with

A = M.view(np.ndarray)
A.shape = -1

Because /usr/bin/time is not present in many modern distributions (Bash built-in time instead), you can use Busybox time implementation with -v argument:

busybox time -v uname -r

It's output is similar to GNU time output. Busybox is pre-installed in most Linux distros (Debian, Ubuntu, etc.). If you using Arch Linux, you can install it with:

sudo pacman -S busybox

My answer is focused to a extended case derived from the one exposed at top.

Suppose you have group of elements from which you want to hide the child elements except first. As an example:

<html>
  <div class='some-group'>
     <div class='child child-0'>visible#1</div>
     <div class='child child-1'>xx</div>
     <div class='child child-2'>yy</div>
  </div>
  <div class='some-group'>
     <div class='child child-0'>visible#2</div>
     <div class='child child-1'>aa</div>
     <div class='child child-2'>bb</div>
  </div>
</html>

1. We want to hide all .child elements on every group. So this will not help because will hide all .child elements except visible#1:

   $('.child:not(:first)').hide();
   

2. The solution (in this extended case) will be:

   $('.some-group').each(function(i,group){
       $(group).find('.child:not(:first)').hide();
   });
   

If you're going to compile a 64bit version(x86_64) of php use: /usr/lib64/

For architectures (i386 ... i686) use /usr/lib/

I recommend compiling php to the same architecture as apache. As you're using a 64bit linux i asume your apache is also compiled for x86_64.

Too late for the question but will post my answer anyway for anyone still needs it. I found an easier way to implement this, without using fragment id or fragment tag, since that's what I was seeking for.

First, I declared my Fragment in my ParentActivity class:

MyFragment myFragment;

Initialized my viewPager as usual, with the fragment I already added in the class above. Then, created a public method called scrollToTop in myFragment that does what I want to do from ParentActivity, let's say scroll my recyclerview to the top.

public void scrollToTop(){
    mMainRecyclerView.smoothScrollToPosition(0);
}

Now, in ParentActivity I called the method as below:

try{
   myFragment.scrollToTop();
}catch (Exception e){
   e.printStackTrace();
}

I strongly favour minimal file headers, by which I mean just:

• The hashbang (#! line) if this is an executable script
• Module docstring
• Imports, grouped in the standard way, eg:

  import os    # standard library
  import sys

  import requests  # 3rd party packages

  from mypackage import (  # local source
      mymodule,
      myothermodule,
  )

ie. three groups of imports, with a single blank line between them. Within each group, imports are sorted. The final group, imports from local source, can either be absolute imports as shown, or explicit relative imports.

Everything else is a waste of time, visual space, and is actively misleading.

If you have legal disclaimers or licencing info, it goes into a separate file. It does not need to infect every source code file. Your copyright should be part of this. People should be able to find it in your LICENSE file, not random source code.

Metadata such as authorship and dates is already maintained by your source control. There is no need to add a less-detailed, erroneous, and out-of-date version of the same info in the file itself.

I don't believe there is any other data that everyone needs to put into all their source files. You may have some particular requirement to do so, but such things apply, by definition, only to you. They have no place in “general headers recommended for everyone”.

If I have the class:

public class MyClass
{
   public void MyMethod()
   {

   }
}

and I then do:

MyClass myClass = null;
myClass.MyMethod();

The second line throws this exception becuase I'm calling a method on a reference type object that is null (I.e. has not been instantiated by calling myClass = new MyClass())

It's worth noting that an OS has one queue for both System.err and System.out. Consider the following code:

public class PrintQueue {
    public static void main(String[] args) {
        for(int i = 0; i < 100; i++) {
            System.out.println("out");
            System.err.println("err");
        }
    }
}

If you compile and run the program, you will see that the order of outputs in console is mixed up.

An OS will remain right order if you work either with System.out or System.err only. But it can randomly choose what to print next to console, if you use both of these.

Even in this code snippet you can see that the order is mixed up sometimes:

public class PrintQueue {
    public static void main(String[] args) {
        System.out.println("out");
        System.err.println("err");
    }
}

Many ways to do it. I guess the key is to do it in the most efficient way possible (without looping the string). I would do it as a char array which can be reversed easily (using C#).

string mystring = "abracadabra";

char[] str = mystring.ToCharArray();
Array.Reverse(str);
string revstring = new string(str);

if (mystring.equals(revstring))
{
    Console.WriteLine("String is a Palindrome");
}

I only check null string with

if ([myString isEqual:[NSNull null]])

Raw Javascript can accomplish the same thing pretty quickly also:

document.getElementById("myElement").onclick = function() { return false; } 

I'd go with

private void Form1_Resize(object sender, EventArgs e)
{
     if (FormWindowState.Minimized == this.WindowState)
     {
          notifyIcon1.Visible = true;
          notifyIcon1.ShowBalloonTip(500);
          this.Hide();    
     }
     else if (FormWindowState.Normal == this.WindowState)
     {
          notifyIcon1.Visible = false;
     }
}

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
     this.Show();
     this.WindowState = FormWindowState.Normal;
}

Use fetch instead of XHR,then the request will not be prelighted even it's cross-domained.

I'm not entirely sure why, but my Postgres installation got a little bit screwed and some files were deleted resulting in the error OP is showing.

Despite the fact that I am able to run commands like brew service retart postgres and see the proper messages, this error persisted.

I went through the postgres documentation and found that my file /usr/local/var/postgres was totally empty. So I ran the following:

initdb /usr/local/var/postgres

It seems some configurations took place with that command.

Then it asked me to run this:

postgres -D /usr/local/var/postgres

And that told me a postmaster.pid file already exists.

I just needed to know if brew would be able to pick up the configs I just ran, so I tested it out.

ls /usr/local/var/postgres

That showed me a postmaster.pid file. I then did brew services stop postgresql, and the postmaster.pid file disappeared. Then I did brew services start postgresql, and VIOLA, the file reappeared.

Then I went ahead and ran my app, which did in fact find the server, however my databases seem to be gone.

Although I know that they may not be gone at all - the new initialization I did may have created a new data_area, and the old one isn't being pointed to. I'd have to look at where that's at and point it back over or just create my databases again.

Hope this helps! Reading the postgres docs helped me a lot. I hate reading answers that are like "Paste this in it works!" because I don't know what the hell is happening and why.

Tested on iTunes 12.5.3.17

1.Open the iTunes select the “Apps” section with in that select the “Library”

2.Now drag and drop the file AppName.ipa in this Library section (Before connecting your iOS device to your computer machine)

3.Now connect your iOS device to your computer machine, we are able to see our device in iTunes…

4.Select your device go to “Apps” section of your device and search your App in the list of apps with "Install" button infront of it.

5.Now hit the “Install” button and then press the “Done” button in bottom right corner, The “Install” button will turn in to “Will Install” one alert will be shown to you with two options “Don’t Apply”, “Apply”, hit on option “Apply”.

6.The “App installation” will start on your device with progress….

7.Finally the app will be installed on your iOS device and you will be able to use it…

I experienced the same issue, it occurred because my ES6 component class was not extending React.Component.

Please note that wildcard expansion is broken for Java 7 on Windows.

Check out this StackOverflow issue for more information.

The workaround is to put a semicolon right after the wildcard. java -cp "somewhere/*;"

Remove the function and check the output of:

var_dump(function_exists('parseDate'));

In which case, change the name of the function.

If you get false, you're including the file with that function twice, replace :

include

by

include_once

And replace :

require

by

require_once

EDIT : I'm just a little too late, post before beat me to it !

.a files are created with the ar utility, and they are libraries. To use it with gcc, collect all .a files in a lib/ folder and then link with -L lib/ and -l<name of specific library>.

Collection of all .a files into lib/ is optional. Doing so makes for better looking directories with nice separation of code and libraries, IMHO.

I'm facing same problem and so far I found:

new Uri(Request.Url,Request.ApplicationPath)

or

Request.Url.GetLeftPart(UriPartial.Authority)+Request.ApplicationPath

Even in base Python you can do the computation in generic form

result = sum(x**2 for x in some_vector) ** 0.5

x ** 2 is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).

Using instead x ** 0.5 to take the square root doesn't do the exact same computations as math.sqrt as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.

I often use x ** 0.5 simply because I don't want to add math just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.

I have two ways for you do that

First: Use type="tel", it'll work like type="number" in mobile, and accept maxlength:

<input type="tel" />

Second: Use a little bit of JavaScript:

<!-- maxlength="2" -->
<input type="tel" onKeyDown="if(this.value.length==2 && event.keyCode!=8) return false;" />

I frequently do something like this when I need to get a few lines surrounding something I've grepped in a log file:

$ grep -n "xlrd" requirements.txt | awk -F ":" '{print $1}'
54

$ python -c "with open('requirements.txt') as file: print ''.join(file.readlines()[52:55])"
wsgiref==0.1.2
xlrd==0.9.2
xlwt==0.7.5

If you want to just uncommit the last commit use this:

git reset HEAD~

work like charm for me.

Combined Solution

I checked that side effect from IE 11 and IE 8 is come from if else statement. So, I replaced it with if else if statement as following.

From the multi browser test, I decided to use Solution 3 for common browsers and Solution 1 for firefox and IE 11.

I referred this answer to detect IE 11.

    // Detect IE version
    var iev=0;
    var ieold = (/MSIE (\d+\.\d+);/.test(navigator.userAgent));
    var trident = !!navigator.userAgent.match(/Trident\/7.0/);
    var rv=navigator.userAgent.indexOf("rv:11.0");

    if (ieold) iev=new Number(RegExp.$1);
    if (navigator.appVersion.indexOf("MSIE 10") != -1) iev=10;
    if (trident&&rv!=-1) iev=11;

    // Firefox or IE 11
    if(typeof InstallTrigger !== 'undefined' || iev == 11) {
        var lastScrollTop = 0;
        $(window).on('scroll', function() {
            st = $(this).scrollTop();
            if(st < lastScrollTop) {
                console.log('Up');
            }
            else if(st > lastScrollTop) {
                console.log('Down');
            }
            lastScrollTop = st;
        });
    }
    // Other browsers
    else {
        $('body').on('mousewheel', function(e){
            if(e.originalEvent.wheelDelta > 0) {
                console.log('Up');
            }
            else if(e.originalEvent.wheelDelta < 0) {
                console.log('Down');
            }
        });
    }

val() returns the value of the <select> element, i.e. the value attribute of the selected <option> element.

Since you actually want the inner text of the selected <option> element, you should match that element and use text() instead:

var nationality = $("#dancerCountry option:selected").text();

From oracle documentation page on Joins

The join method allows one thread to wait for the completion of another.

If t1 is a Thread object whose thread is currently executing,

t1.join() : causes the current thread to pause execution until t1's thread terminates.

If t2 is a Thread object whose thread is currently executing,

t2.join(); causes the current thread to pause execution until t2's thread terminates.

join API is low level API, which has been introduced in earlier versions of java. Lot of things have been changed over a period of time (especially with jdk 1.5 release) on concurrency front.

You can achieve the same with java.util.concurrent API. Some of the examples are

1. Using invokeAll on ExecutorService
2. Using CountDownLatch
3. Using ForkJoinPool or newWorkStealingPool of Executors(since java 8)

Refer to related SE questions:

wait until all threads finish their work in java

You need to make your regex pattern 'non-greedy' by adding a '?' after the '.+'

By default, '*' and '+' are greedy in that they will match as long a string of chars as possible, ignoring any matches that might occur within the string.

Non-greedy makes the pattern only match the shortest possible match.

See Watch Out for The Greediness! for a better explanation.

Or alternately, change your regex to

\(([^\)]+)\)

which will match any grouping of parens that do not, themselves, contain parens.

replace below lines:

<permission android:name="com.myapp.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.myapp.permission.C2D_MESSAGE" 
android:protectionLevel="signature" /> 

Just declare

table = data.frame()

when you try to rbind the first line it will create the columns

Try to change where Member class

public function users() {
    return $this->hasOne('User');
} 

return $this->belongsTo('User');

In my case, i was using vs 2010 with crystal report. Innerexception revealed root element is missing error. Go to directory like C:\Users\sam\AppData\Local\dssms\dssms.vshost.exe_Url_uy5is55gioxym5avqidulehrfjbdsn13\1.0.0.0 which is given in the innermessage and make sure user.config is proper XML (mine was blank for some reason).

Add the sheet name infront of the cell, e.g.:

=COUNTIFS(stock!A:A,"M",stock!C:C,"Yes")

Assumes the sheet name is "stock"

It sounds like you do not have django installed. You should check the directory produced by this command:

python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"

To see if you have the django packages in there.

If there's no django folder inside of site-packages, then you do not have django installed (at least for that version of python).

It is possible you have more than one version of python installed and django is inside of another version. You can find out all the versions of python if you type python and then press TAB. Here are all the different python's I have.

$python
python            python2-config    python2.6         python2.7-config  pythonw2.5
python-config     python2.5         python2.6-config  pythonw           pythonw2.6
python2           python2.5-config  python2.7         pythonw2          pythonw2.7

You can do the above command for each version of python and look inside the site-packages directory of each to see if any of them have django installed. For example:

python2.5 -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
python2.6 -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"

If you happen to find django inside of say python2.6, try your original command with

python2.6 manage.py ...

For Sublime Text users.

Set following properly in you Setting-User configuration.

"trim_trailing_white_space_on_save": true

I find letter identifiers to be more readable and more indicative of parsed type:

1 - 7f / 10
1 - 7 / 10f

or:

1 - 7d / 10
1 - 7 / 10d

If you run Linux and have the extension you could simply read the MIME type from /etc/mime.types by making a hash array. You can then store that in memory and simply call the MIME by array key :)

/**
 * Helper function to extract all mime types from the default Linux /etc/mime.types
 */
function get_mime_types() {
    $mime_types = array();
    if (
        file_exists('/etc/mime.types') &&
        ($fh = fopen('/etc/mime.types', 'r')) !== false
    ) {
        while (($line = fgets($fh)) !== false) {
            if (!trim($line) || substr($line, 0, 1) === '#') continue;
            $mime_type = preg_split('/\t+/', rtrim($line));
            if (
                is_array($mime_type) &&
                isset($mime_type[0]) && $mime_type[0] &&
                isset($mime_type[1]) && $mime_type[1]
            ) {
                foreach (explode(' ', $mime_type[1]) as $ext) {
                    $mime_types[$ext] = $mime_type[0];
                }
            }
        }
        fclose($fh);
    }
    return $mime_types;
}

You can think of O(log N) intuitively by saying the time is proportional to the number of digits in N.

If an operation performs constant time work on each digit or bit of an input, the whole operation will take time proportional to the number of digits or bits in the input, not the magnitude of the input; thus, O(log N) rather than O(N).

If an operation makes a series of constant time decisions each of which halves (reduces by a factor of 3, 4, 5..) the size of the input to be considered, the whole will take time proportional to log base 2 (base 3, base 4, base 5...) of the size N of the input, rather than being O(N).

And so on.

While using formControl, you have to import ReactiveFormsModule to your imports array.

Example:

import {FormsModule, ReactiveFormsModule} from '@angular/forms';

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    ReactiveFormsModule,
    MaterialModule,
  ],
  ...
})
export class AppModule {}

The answer is simple. Just look at the image.

If you can't access https://dl-ssl.google.com/android/eclipse/ simply try to use http:// instead of https://

open() is a low-level os call. fdopen() converts an os-level file descriptor to the higher-level FILE-abstraction of the C language. fopen() calls open() in the background and gives you a FILE-pointer directly.

There are several advantages to using FILE-objects rather raw file descriptors, which includes greater ease of usage but also other technical advantages such as built-in buffering. Especially the buffering generally results in a sizeable performance advantage.

Yes, opacity can only work on top-level windows. It uses a hardware feature of the video adapter, that doesn't support child windows, like Panel. The only top-level Control derived class in Winforms is Form.

Several of the 'pure' Winform controls, the ones that do their own painting instead of letting a native Windows control do the job, do however support a transparent BackColor. Panel is one of them. It uses a trick, it asks the Parent to draw itself to produce the background pixels. One side-effect of this trick is that overlapping controls doesn't work, you only see the parent pixels, not the overlapped controls.

This sample form shows it at work:

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        this.BackColor = Color.White;
        panel1.BackColor = Color.FromArgb(25, Color.Black);
    }
    protected override void OnPaint(PaintEventArgs e) {
        e.Graphics.DrawLine(Pens.Yellow, 0, 0, 100, 100);
    }
}

If that's not good enough then you need to consider stacking forms on top of each other. Like this.

Notable perhaps is that this restriction is lifted in Windows 8. It no longer uses the video adapter overlay feature and DWM (aka Aero) cannot be turned off anymore. Which makes opacity/transparency on child windows easy to implement. Relying on this is of course future-music for a while to come. Windows 7 will be the next XP :)

In case, you want to keep old field (For ex: name). The query will be:

INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE    
name=name, age=19;

To get the top N elements from your python dictionary one can use the following line of code:

list(dictionaryName.items())[:N]

In your case you can change it to:

list(d.items())[:4]

Calling readOnly=false from readOnly=true doesn't work since the previous transaction continues.

In your example, the handle() method on your service layer is starting a new read-write transaction. If the handle method in turn calls service methods that annotated read-only, the read-only will take no effect as they will participate in the existing read-write transaction instead.

If it is essential for those methods to be read-only, then you can annotate them with Propagation.REQUIRES_NEW, and they will then start a new read-only transaction rather than participate in the existing read-write transaction.

Here is a worked example, CircuitStateRepository is a spring-data JPA repository.

BeanS calls a transactional=read-only Bean1, which does a lookup and calls transactional=read-write Bean2 which saves a new object.

• Bean1 starts a read-only tx.

31 09:39:44.199 [pool-1-thread-1] DEBUG o.s.orm.jpa.JpaTransactionManager - Creating new transaction with name [nz.co.vodafone.wcim.business.Bean1.startSomething]: PROPAGATION_REQUIRED,ISOLATION_DEFAULT,readOnly; ''

• Bean 2 pariticipates in it.

  31 09:39:44.230 [pool-1-thread-1] DEBUG o.s.orm.jpa.JpaTransactionManager - Participating in existing transaction

  Nothing is committed to the database.

Now change Bean2 @Transactional annotation to add propagation=Propagation.REQUIRES_NEW

• Bean1 starts a read-only tx.

  31 09:31:36.418 [pool-1-thread-1] DEBUG o.s.orm.jpa.JpaTransactionManager - Creating new transaction with name [nz.co.vodafone.wcim.business.Bean1.startSomething]: PROPAGATION_REQUIRED,ISOLATION_DEFAULT,readOnly; ''

• Bean2 starts a new read-write tx

  31 09:31:36.449 [pool-1-thread-1] DEBUG o.s.orm.jpa.JpaTransactionManager - Suspending current transaction, creating new transaction with name [nz.co.vodafone.wcim.business.Bean2.createSomething]

And the changes made by Bean2 are now committed to the database.

Here's the example, tested with spring-data, hibernate and oracle.

@Named
public class BeanS {    
    @Inject
    Bean1 bean1;

    @Scheduled(fixedRate = 20000)
    public void runSomething() {
        bean1.startSomething();
    }
}

@Named
@Transactional(readOnly = true)
public class Bean1 {    
    Logger log = LoggerFactory.getLogger(Bean1.class);

    @Inject
    private CircuitStateRepository csr;

    @Inject
    private Bean2 bean2;

    public void startSomething() {    
        Iterable<CircuitState> s = csr.findAll();
        CircuitState c = s.iterator().next();
        log.info("GOT CIRCUIT {}", c.getCircuitId());
        bean2.createSomething(c.getCircuitId());    
    }
}

@Named
@Transactional(readOnly = false)
public class Bean2 {    
    @Inject
    CircuitStateRepository csr;

    public void createSomething(String circuitId) {
        CircuitState c = new CircuitState(circuitId + "-New-" + new DateTime().toString("hhmmss"), new DateTime());

        csr.save(c);
     }
}

Incrementing dates can be accomplished using timedelta objects:

import datetime

datetime.datetime.now() + datetime.timedelta(days=1)

Look up timedelta objects in the Python docs: http://docs.python.org/library/datetime.html

Use list, it will solve problem

Step1:

 result=YOUR_MODELE_NAME.objects.values('PROP1','PROP2').all();

Step2:

 result=list(result)  #after getting data from model convert result to list

Step3:

 return HttpResponse(json.dumps(result), content_type = "application/json")

The below code worked for me.

I've created a method for seekbar

@Override
public void onPrepared(MediaPlayer mediaPlayer) {
    mp.start();
     getDurationTimer();
    getSeekBarStatus();


}
//Creating duration time method
public void getDurationTimer(){
    final long minutes=(mSongDuration/1000)/60;
    final int seconds= (int) ((mSongDuration/1000)%60);
    SongMaxLength.setText(minutes+ ":"+seconds);


}



 //creating a method for seekBar progress
public void getSeekBarStatus(){

    new Thread(new Runnable() {

        @Override
        public void run() {
            // mp is your MediaPlayer
            // progress is your ProgressBar

            int currentPosition = 0;
            int total = mp.getDuration();
            seekBar.setMax(total);
            while (mp != null && currentPosition < total) {
                try {
                    Thread.sleep(1000);
                    currentPosition = mp.getCurrentPosition();
                } catch (InterruptedException e) {
                    return;
                }
                seekBar.setProgress(currentPosition);

            }
        }
    }).start();





    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        int progress=0;

        @Override
        public void onProgressChanged(final SeekBar seekBar, int ProgressValue, boolean fromUser) {
            if (fromUser) {
                mp.seekTo(ProgressValue);//if user drags the seekbar, it gets the position and updates in textView.
            }
            final long mMinutes=(ProgressValue/1000)/60;//converting into minutes
            final int mSeconds=((ProgressValue/1000)%60);//converting into seconds
            SongProgress.setText(mMinutes+":"+mSeconds);
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });
}

SongProgress and SongMaxLength are the TextView to show song duration and song length.

Since you want to check whether textboxes contains any value or not your code should do the job. You should be more specific about the error you are having. You can also do:

if(textBox1.Text == string.Empty || textBox2.Text == string.Empty)
   {
    MessageBox.Show("You must enter a value into both boxes");
   }

EDIT 2: based on @JonSkeet comments:

Usage of string.Compare is not required as per OP's original unedited post. String.Equals should do the job if one wants to compare strings, and StringComparison may be used to ignore case for the comparison. string.Compare should be used for order comparison. Originally the question contain this comparison,

string testString = "This is a test";
string testString2 = "This is not a test";

if (testString == testString2)
{
    //do some stuff;
}

the if statement can be replaced with

if(testString.Equals(testString2))

or following to ignore case.

if(testString.Equals(testString2,StringComparison.InvariantCultureIgnoreCase)) 

Try This:

SELECT systimestamp INTO time_db FROM dual ;

DBMS_OUTPUT.PUT_LINE('time before procedure ' || time_db);

If you put your JavaScript code in the PHP file, you can, but not otherwise. For example:

page.php (this will work)

function jst()
{
    var i = 0;
    i = <?php echo 35; ?>;
    alert(i);
}

page.js (this won't work)

function jst()
{
    var i = 0;
    i = <?php echo 35; ?>
    alert(i);
}

You can run brew link openssl to link it into /usr/local, if you don't mind the potential problem highlighted in the warning message. Otherwise, you can add the openssl bin directory to your path:

export PATH=$(brew --prefix openssl)/bin:$PATH

IMHO returning first mac address isn't good idea, especially when virtual machines are hosted. Therefore i check send/received bytes sum and select most used connection, that is not perfect, but should be correct 9/10 times.

public string GetDefaultMacAddress()
{
    Dictionary<string, long> macAddresses = new Dictionary<string, long>();
    foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
    {
        if (nic.OperationalStatus == OperationalStatus.Up)
            macAddresses[nic.GetPhysicalAddress().ToString()] = nic.GetIPStatistics().BytesSent + nic.GetIPStatistics().BytesReceived;
    }
    long maxValue = 0;
    string mac = "";
    foreach(KeyValuePair<string, long> pair in macAddresses)
    {
        if (pair.Value > maxValue)
        {
            mac = pair.Key;
            maxValue = pair.Value;
        }
    }
    return mac;
}

In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction() but instead wrap your code in DB::beginTransaction and DB::commit/DB::rollback():

DB::beginTransaction();

try {
    DB::insert(...);
    DB::insert(...);
    DB::insert(...);

    DB::commit();
    // all good
} catch (\Exception $e) {
    DB::rollback();
    // something went wrong
}

See the transaction docs.

Since you're returning a string as JSON, that string will include the opening and closing quotes in the raw response. So your response should probably look like:

"abc123XYZ=="

or whatever...You can try confirming this with Fiddler.

My guess is that the result.Content is the raw string, including the quotes. If that's the case, then result.Content will need to be deserialized before you can use it.

For Chrome on Mac, if you have multiple profiles, you can find it under your profile folder, either Default or Profile #. i.e either

~/Library/Application Support/Google/Chrome/Default/Extensions/ or ~/Library/Application Support/Google/Chrome/<Profile 1>/Extensions/

function scroll_down(){
    $.noConflict();
    jQuery(document).ready(function($) {
        $('html, body').animate({
            scrollTop : $("#bottom").offset().top
        }, 1);
    });
    return false;
}

here "bottom" is the div tag id where you want to scroll to. For changing the animation effects, you can change the time from '1' to a different value

It seems to me the simplest way to do it with Selenium is to intercept the XHR that sends back the browser fingerprint.

But since this is a Selenium-only problem, its better just to use something else. Selenium is supposed to make things like this easier, not way harder.

There is an important detail that has been omitted in the answer above.

MySQL imposes a limit of 65,535 bytes for the max size of each row. The size of a VARCHAR column is counted towards the maximum row size, while TEXT columns are assumed to be storing their data by reference so they only need 9-12 bytes. That means even if the "theoretical" max size of your VARCHAR field is 65,535 characters you won't be able to achieve that if you have more than one column in your table.

Also note that the actual number of bytes required by a VARCHAR field is dependent on the encoding of the column (and the content). MySQL counts the maximum possible bytes used toward the max row size, so if you use a multibyte encoding like utf8mb4 (which you almost certainly should) it will use up even more of your maximum row size.

Correction: Regardless of how MySQL computes the max row size, whether or not the VARCHAR/TEXT field data is ACTUALLY stored in the row or stored by reference depends on your underlying storage engine. For InnoDB the row format affects this behavior. (Thanks Bill-Karwin)

Reasons to use TEXT:

• If you want to store a paragraph or more of text
• If you don't need to index the column
• If you have reached the row size limit for your table

Reasons to use VARCHAR:

• If you want to store a few words or a sentence
• If you want to index the (entire) column
• If you want to use the column with foreign-key constraints

Since your issue is mostly stylistic (not wanting to fill up the constructor with a bunch of declarations) it can be solved stylistically as well.

The way I view it, many class based languages have the constructor be a function named after the class name itself. Stylistically we could use that that to make an ES6 class that stylistically still makes sense but does not group the typical actions taking place in the constructor with all the property declarations we're doing. We simply use the actual JS constructor as the "declaration area", then make a class named function that we otherwise treat as the "other constructor stuff" area, calling it at the end of the true constructor.

"use strict";

class MyClass
{
    // only declare your properties and then call this.ClassName(); from here
    constructor(){
        this.prop1 = 'blah 1';
        this.prop2 = 'blah 2';
        this.prop3 = 'blah 3';
        this.MyClass();
    }

    // all sorts of other "constructor" stuff, no longer jumbled with declarations
    MyClass() {
        doWhatever();
    }
}

Both will be called as the new instance is constructed.

Sorta like having 2 constructors where you separate out the declarations and the other constructor actions you want to take, and stylistically makes it not too hard to understand that's what is going on too.

I find it's a nice style to use when dealing with a lot of declarations and/or a lot of actions needing to happen on instantiation and wanting to keep the two ideas distinct from each other.

NOTE: I very purposefully do not use the typical idiomatic ideas of "initializing" (like an init() or initialize() method) because those are often used differently. There is a sort of presumed difference between the idea of constructing and initializing. Working with constructors people know that they're called automatically as part of instantiation. Seeing an init method many people are going to assume without a second glance that they need to be doing something along the form of var mc = MyClass(); mc.init();, because that's how you typically initialize. I'm not trying to add an initialization process for the user of the class, I'm trying to add to the construction process of the class itself.

While some people may do a double-take for a moment, that's actually the bit of the point: it communicates to them that the intent is part of construction, even if that makes them do a bit of a double take and go "that's not how ES6 constructors work" and take a second looking at the actual constructor to go "oh, they call it at the bottom, I see", that's far better than NOT communicating that intent (or incorrectly communicating it) and probably getting a lot of people using it wrong, trying to initialize it from the outside and junk. That's very much intentional to the pattern I suggest.

For those that don't want to follow that pattern, the exact opposite can work too. Farm the declarations out to another function at the beginning. Maybe name it "properties" or "publicProperties" or something. Then put the rest of the stuff in the normal constructor.

"use strict";

class MyClass
{
    properties() {
        this.prop1 = 'blah 1';
        this.prop2 = 'blah 2';
        this.prop3 = 'blah 3';
    }

    constructor() {
        this.properties();
        doWhatever();
    }
}

Note that this second method may look cleaner but it also has an inherent problem where properties gets overridden as one class using this method extends another. You'd have to give more unique names to properties to avoid that. My first method does not have this problem because its fake half of the constructor is uniquely named after the class.

RESTful Resource controller

A RESTful resource controller sets up some default routes for you and even names them.

Route::resource('users', 'UsersController');

Gives you these named routes:

Verb          Path                        Action  Route Name
GET           /users                      index   users.index
GET           /users/create               create  users.create
POST          /users                      store   users.store
GET           /users/{user}               show    users.show
GET           /users/{user}/edit          edit    users.edit
PUT|PATCH     /users/{user}               update  users.update
DELETE        /users/{user}               destroy users.destroy

And you would set up your controller something like this (actions = methods)

class UsersController extends BaseController {

    public function index() {}

    public function show($id) {}

    public function store() {}

}

You can also choose what actions are included or excluded like this:

Route::resource('users', 'UsersController', [
    'only' => ['index', 'show']
]);

Route::resource('monkeys', 'MonkeysController', [
    'except' => ['edit', 'create']
]);

API Resource controller

Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create and edit routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create nor edit methods.

Route::apiResource('users', 'UsersController');

RESTful Resource Controller documentation

Implicit controller

An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.

Route::controller('users', 'UserController');

Would lead you to set up the controller with a sort of RESTful naming scheme:

class UserController extends BaseController {

    public function getIndex()
    {
        // GET request to index
    }

    public function getShow($id)
    {
        // get request to 'users/show/{id}'
    }

    public function postStore()
    {
        // POST request to 'users/store'
    }

}

Implicit Controller documentation

It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes. I typically use RESTful Resource controllers in combination with explicit routes.

I just installed vim by:

brew install vim

now the new vim is accessed by vim and the old vim (built-in vim) by vi

Windows default install location for Webstorm:

C:\Program Files\JetBrains\WebStorm 2019.1.3\bin\idea.properties

I went x4 default for intellisense and x5 for file size

#---------------------------------------------------------------------
# Maximum file size (kilobytes) IDE should provide code assistance for.

I never save an R workspace. I use import scripts and data scripts and output any especially large data objects that I don't want to recreate often to files. This way I always start with a fresh workspace and don't need to clean out large objects. That is a very nice function though.

It can be complicated to compute a diff in your head from the different sections in $MERGED and apply that. In my setup, meld helps by showing you these diffs visually, using:

[merge]
    tool = mymeld
    conflictstyle = diff3

[mergetool "mymeld"]
    cmd = meld --diff $BASE $REMOTE --diff $REMOTE $LOCAL --diff $LOCAL $MERGED

It looks strange but offers a very convenient work-flow, using three tabs:

1. in tab 1 you see (from left to right) the change that you should make in tab 2 to solve the merge conflict.

2. in the right side of tab 2 you apply the "change that you should make" and copy the entire file contents to the clipboard (using ctrl-a and ctrl-c).

3. in tab 3 replace the right side with the clipboard contents. If everything is correct, you will now see - from left to right - the same change as shown in tab 1 (but with different contexts). Save the changes made in this tab.

Notes:

• don't edit anything in tab 1
• don't save anything in tab 2 because that will produce annoying popups in tab 3

This should do:

Assembly assem = Assembly.GetExecutingAssembly();
AssemblyName aName = assem.GetName();
return aName.Version.ToString();

DateTime does not know its timezone offset. There is no built-in method to return the offset or the timezone name (e.g. EAT, CEST, EST etc).

Like suggested by others, you can convert your date to UTC:

DateTime localtime = new DateTime.Now;
var utctime = localtime.ToUniversalTime();

and then only calculate the difference:

TimeSpan difference = localtime - utctime;

Also you may convert one time to another by using the DateTimeOffset:

DateTimeOffset targetTime = DateTimeOffset.Now.ToOffset(new TimeSpan(5, 30, 0));

But this is sort of lossy compression - the offset alone cannot tell you which time zone it is as two different countries may be in different time zones and have the same time only for part of the year (eg. South Africa and Europe). Also, be aware that summer daylight saving time may be introduced at different dates (EST vs CET - a 3-week difference).

You can get the name of your local system time zone using TimeZoneInfo class:

TimeZoneInfo localZone = TimeZoneInfo.Local;
localZone.IsDaylightSavingTime(localtime) ? localZone.DaylightName : localZone.StandardName

I agree with Gerrie Schenck, please read the article he suggested.

Thanks to John Magnolia. This is my postForm function that I am using in my Symfony projects and it is fine now to work with CK Editor.

function postForm($form, callback)
{
  // Get all form values
  var values = {};
  var fields = {};

  for(var instanceName in CKEDITOR.instances){
      CKEDITOR.instances[instanceName].updateElement();
  }

  $.each($form.serializeArray(), function(i, field) {
      values[field.name] = field.value;
  });

  // Throw the form values to the server!
  $.ajax({
      type        : $form.attr('method'),
      url         : $form.attr('action'),
      data        : values,
      success     : function(data) {
          callback( data );
      }
  });

Try using getTime (mdn doc) :

var diff = Math.abs(date1.getTime() - date2.getTime()) / 3600000;
if (diff < 18) { /* do something */ }

Using Math.abs() we don't know which date is the smallest. This code is probably more relevant :

var diff = (date1 - date2) / 3600000;
if (diff < 18) { array.push(date1); }

You can try htmlspecialchars_decode($string). It works for me.

TLDR; MySql does not have an equivalent concept of varchar(max), this is a MS SQL Server feature.

What is VARCHAR(max)?

varchar(max) is a feature of Microsoft SQL Server.

The amount of data that a column could store in Microsoft SQL server versions prior to version 2005 was limited to 8KB. In order to store more than 8KB you would have to use TEXT, NTEXT, or BLOB columns types, these column types stored their data as a collection of 8K pages separate from the table data pages; they supported storing up to 2GB per row.

The big caveat to these column types was that they usually required special functions and statements to access and modify the data (e.g. READTEXT, WRITETEXT, and UPDATETEXT)

In SQL Server 2005, varchar(max) was introduced to unify the data and queries used to retrieve and modify data in large columns. The data for varchar(max) columns is stored inline with the table data pages.

As the data in the MAX column fills an 8KB data page an overflow page is allocated and the previous page points to it forming a linked list. Unlike TEXT, NTEXT, and BLOB the varchar(max) column type supports all the same query semantics as other column types.

So varchar(MAX) really means varchar(AS_MUCH_AS_I_WANT_TO_STUFF_IN_HERE_JUST_KEEP_GROWING) and not varchar(MAX_SIZE_OF_A_COLUMN).

MySql does not have an equivalent idiom.

In order to get the same amount of storage as a varchar(max) in MySql you would still need to resort to a BLOB column type. This article discusses a very effective method of storing large amounts of data in MySql efficiently.

I had the same issue, if you enable Microsoft Scripting Runtime you should be good. You can do so under tools > references > and then check the box for Microsoft Scripting Runtime. This should solve your issue.

The read method returns a sequence of bytes as a string. To convert from a string byte-sequence to binary data, use the built-in struct module: http://docs.python.org/library/struct.html.

import struct

print(struct.unpack('i', fin.read(4)))

Note that unpack always returns a tuple, so struct.unpack('i', fin.read(4))[0] gives the integer value that you are after.

You should probably use the format string '<i' (< is a modifier that indicates little-endian byte-order and standard size and alignment - the default is to use the platform's byte ordering, size and alignment). According to the BMP format spec, the bytes should be written in Intel/little-endian byte order.

for phpspreadsheet:

$sheet = $spreadsheet->getActiveSheet(); // $spreadsheet is instance of PhpOffice\PhpSpreadsheet\Spreadsheet

foreach (
    range(
         1, 
         Coordinate::columnIndexFromString($sheet->getHighestColumn(1))
    ) as $column
) {
    $sheet
          ->getColumnDimension(Coordinate::stringFromColumnIndex($column))
          ->setAutoSize(true);
}

You can get a list of column names by running:

SELECT name FROM PRAGMA_TABLE_INFO('your_table');
name      
tbl_name  
rootpage  
sql

You can check if a certain column exists by running:

SELECT 1 FROM PRAGMA_TABLE_INFO('your_table') WHERE name='sql';
1

Reference:

https://www.sqlite.org/pragma.html#pragfunc

In version 12.2 and above, the simplest way to make the query case insensitive is this:

SELECT * FROM TABLE WHERE TABLE.NAME COLLATE BINARY_CI Like 'IgNoReCaSe'

java.util.MissingResourceException: Can't find bundle for base name
    org.jfree.chart.LocalizationBundle, locale en_US

To the point, the exception message tells in detail that you need to have either of the following files in the classpath:

/org/jfree/chart/LocalizationBundle.properties

or

/org/jfree/chart/LocalizationBundle_en.properties

or

/org/jfree/chart/LocalizationBundle_en_US.properties

Also see the official Java tutorial about resourcebundles for more information.

But as this is actually a 3rd party managed properties file, you shouldn't create one yourself. It should be already available in the JFreeChart JAR file. So ensure that you have it available in the classpath during runtime. Also ensure that you're using the right version, the location of the propertiesfile inside the package tree might have changed per JFreeChart version.

When executing a JAR file, you can use the -cp argument to specify the classpath. E.g.:

java -jar -cp c:/path/to/jfreechart.jar yourfile.jar

Alternatively you can specify the classpath as class-path entry in the JAR's manifest file. You can use in there relative paths which are relative to the JAR file itself. Do not use the %CLASSPATH% environment variable, it's ignored by JAR's and everything else which aren't executed with java.exe without -cp, -classpath and -jar arguments.

For those newbies like me, don't assign variable to service response, meaning do

export class ShopComponent implements OnInit {
  public productsArray: Product[];

  ngOnInit() {
      this.productService.getProducts().subscribe(res => {
        this.productsArray = res;
      });
  }
}

Instead of

export class ShopComponent implements OnInit {
    public productsArray: Product[];

    ngOnInit() {
        this.productsArray = this.productService.getProducts().subscribe();
    }
}

I had similar error: "Expecting value: line 1 column 1 (char 0)"

It helped for me to add "myfile.seek(0)", move the pointer to the 0 character

with open(storage_path, 'r') as myfile:

    myfile.seek(0)
    Bank_0 = json.load(myfile)
