I am sure a number of you have heard about machine learning. A dozen of you might even know what it is. And a couple of you might have worked with machine learning algorithms too.  You see where this is going? Not a lot of people are familiar with the technology that will be absolutely essential 5 years from now. Siri is machine learning. Amazon’s Alexa is machine learning. Ad and shopping item recommender systems are machine learning.  Let’s try to understand machine learning with a simple analogy of a 2 year old boy. Just for fun, let’s call him Kylo Ren

Let’s assume Kylo Ren saw an elephant. What will his brain tell him ?(Remember he has minimum thinking capacity, even if he is the successor to Vader). His brain will tell him that he saw a big moving creature which was grey in color. He sees a cat next, and his brain tells him that it is a small moving creature which is golden in color. Finally, he sees a light saber next and his brain tells him that it is a non-living object which he can play with!

His brain at this point knows that saber is different from the elephant and the cat, because the saber is something to play with and doesn’t move on its own. His brain can figure this much out even if Kylo doesn’t know what movable means. This simple phenomenon is called Clustering .

Machine learning is nothing but the mathematical version of this process. A lot of people who study statistics realized that they can make some equations work in the same way as brain works.  Brain can cluster similar objects, brain can learn from mistakes and brain can learn to identify things.

All of this can be represented with statistics, and the computer based simulation of this process is called Machine Learning. Why do we need the computer based simulation? because computers can do heavy math faster than human brains.  I would love to go into the mathematical/statistical part of machine learning but you don’t wanna jump into that without clearing some concepts first.

Let’s get back to Kylo Ren. Let’s say Kylo picks up the saber and starts playing with it. He accidentally hits a stormtrooper and the stormtrooper gets injured. He doesn’t understand what’s going on and continues playing. Next he hits a cat and the cat gets injured. This time Kylo is sure he has done something bad, and tries to be somewhat careful. But given his bad saber skills, he hits the elephant and is absolutely sure that he is in trouble.  He becomes extremely careful thereafter, and only hits his dad on purpose as we saw in Force Awakens!!

This entire process of learning from your mistake can be mimicked with equations, where the feeling of doing something wrong is represented by an error or cost. This process of identifying what not to do with a saber is called Classification .  Clustering and Classification are the absolute basics of machine learning. Let’s look at the difference between them.

Kylo differentiated between animals and light saber because his brain decided that light sabers cant move by themselves and are therefore, different. The decision was based solely upon the objects present (data) and no external help or advice was provided.  In contrast to this, Kylo differentiated the importance of being careful with light saber by first observing what hitting an object can do. The decision wasn’t completely based on the saber, but on what it could do to different objects . In short, there was some help here.

Because of this difference in learning, Clustering is called an unsupervised learning method and Classification is called a supervised learning method.  They are very different in the machine learning world, and are often dictated by the kind of data present. Obtaining labelled data (or things that help us learn , like stormtrooper,elephant and cat in Kylo’s case) is often not easy and becomes very complicated when the data to be differentiated is large. On the other hand, learning without labels can have it’s own disadvantages , like not knowing what are the label titles.  If Kylo was to learn being careful with the saber without any examples or help, he wouldn’t know what it would do. He would just know that it is not suppose to be done. It’s kind of a lame analogy but you get the point!

We are just getting started with Machine Learning. Classification itself can be classification of continuous numbers or classification of labels. For instance, if Kylo had to classify what each stormtrooper’s height is, there would be a lot of answers because the heights can be 5.0, 5.01, 5.011, etc. But a simple classification like types of light sabers (red,blue.green) would have very limited answers. Infact they can be represented with simple numbers. Red can be 0 , Blue can be 1 and Green can be 2.

If you know basic math, you know that 0,1,2 and 5.1,5.01,5.011 are different and are called discrete and continuous numbers respectively. The classification of discrete numbers is called Logistic Regression , and classification of continuous numbers is called Regression.  Logistic Regression is also known as categorical classification, so don’t be confused when you read this term elsewhere

This was a very basic introduction to Machine Learning. I will dwell into the statistical side in my next post. Please let me know if I need any corrections :)

Second part posted here.

If you use MATLAB, any version since 2013b that is, you can make use of the function evalclusters to find out what should the optimal k be for a given dataset.

This function lets you choose from among 3 clustering algorithms - kmeans, linkage and gmdistribution.

It also lets you choose from among 4 clustering evaluation criteria - CalinskiHarabasz, DaviesBouldin, gap and silhouette.

A simple solution is the library factoextra. You can change the clustering method and the method for calculate the best number of groups. For example if you want to know the best number of clusters for a k- means:

Data: mtcars

library(factoextra)   
fviz_nbclust(mtcars, kmeans, method = "wss") +
      geom_vline(xintercept = 3, linetype = 2)+
      labs(subtitle = "Elbow method")

Finally, we get a graph like:

Just multiply the number by 100, round, and divide the resulting number by 100.

Generally speaking, you can update your index mapping using the put mapping api (reference here) :

curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
    "advert_type" : {
        "properties" : {

          //your new mapping properties

        }
    }
}
'

It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.

You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.

Finally, you will have to reindex your data for your new mapping to be taken into account.

The best solution would really be to create a new index.

If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.

For Swift 3.0+

extension String {
    func SizeOf_String( font: UIFont) -> CGSize {
        let fontAttribute = [NSFontAttributeName: font]
        let size = self.size(attributes: fontAttribute)  // for Single Line
       return size;
   }
}

Use it like...

        let Str = "ABCDEF"
        let Font =  UIFont.systemFontOfSize(19.0)
        let SizeOfString = Str.SizeOfString(font: Font!)

You can do this if you use an <a> tag instead of a button. I know it's not exactly what you asked for, but it might give you some other options if you cannot find a solution to this:

Borrowing from a demo from another answer here I produced this:

a {_x000D_
  display: block;_x000D_
  font-size: 18px;_x000D_
  border: 2px solid gray;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  text-align: center;_x000D_
  line-height: 100px;_x000D_
}_x000D_
_x000D_
a:active {_x000D_
  font-size: 18px;_x000D_
  border: 2px solid green;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
a:target {_x000D_

  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}

<a id="btn" href="#btn">Demo</a>

Notice the use of :target; this will be the style applied when the element is targeted via the hash. Which also means your HTML will need to be this: <a id="btn" href="#btn">Demo</a> a link targeting itself. and the demo http://jsfiddle.net/rlemon/Awdq5/4/

Thanks to @BenjaminGruenbaum here is a better demo: http://jsfiddle.net/agzVt/

_{Also, as a footnote: this should really be done with JavaScript and applying / removing CSS classes from the element. It would be much less convoluted.}

This is an old question but some of the answers I see posted don't actually work because zip is not scriptable. Other answers didn't bother to import operator and provide more info about this module and its benefits here.

There are at least two good idioms for this problem. Starting with the example input you provided:

X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0,   1,   1,   0,   1,   2,   2,   0,   1 ]

Using the "Decorate-Sort-Undecorate" idiom

This is also known as the Schwartzian_transform after R. Schwartz who popularized this pattern in Perl in the 90s:

# Zip (decorate), sort and unzip (undecorate).
# Converting to list to script the output and extract X
list(zip(*(sorted(zip(Y,X)))))[1]                                                                                                                       
# Results in: ('a', 'd', 'h', 'b', 'c', 'e', 'i', 'f', 'g')

Note that in this case Y and X are sorted and compared lexicographically. That is, the first items (from Y) are compared; and if they are the same then the second items (from X) are compared, and so on. This can create unstable outputs unless you include the original list indices for the lexicographic ordering to keep duplicates in their original order.

Using the operator module

This gives you more direct control over how to sort the input, so you can get sorting stability by simply stating the specific key to sort by. See more examples here.

import operator    

# Sort by Y (1) and extract X [0]
list(zip(*sorted(zip(X,Y), key=operator.itemgetter(1))))[0]                                                                                                 
# Results in: ('a', 'd', 'h', 'b', 'c', 'e', 'i', 'f', 'g')

Imports System.Runtime.InteropServices

In addition to Laurence's answer, if you also want to make it null-safe:

private static <T> boolean listEqualsIgnoreOrder(List<T> list1, List<T> list2) {
    if (list1 == null)
        return list2==null;
    if (list2 == null)
        return list1 == null;
    return new HashSet<>(list1).equals(new HashSet<>(list2));
}

The callback is passed the element, the index, and the array itself.

arr.forEach(function(part, index, theArray) {
  theArray[index] = "hello world";
});

edit — as noted in a comment, the .forEach() function can take a second argument, which will be used as the value of this in each call to the callback:

arr.forEach(function(part, index) {
  this[index] = "hello world";
}, arr); // use arr as this

That second example shows arr itself being set up as this in the callback.One might think that the array involved in the .forEach() call might be the default value of this, but for whatever reason it's not; this will be undefined if that second argument is not provided.

(Note: the above stuff about this does not apply if the callback is a => function, because this is never bound to anything when such functions are invoked.)

Also it's important to remember that there is a whole family of similar utilities provided on the Array prototype, and many questions pop up on Stackoverflow about one function or another such that the best solution is to simply pick a different tool. You've got:

• forEach for doing a thing with or to every entry in an array;
• filter for producing a new array containing only qualifying entries;
• map for making a one-to-one new array by transforming an existing array;
• some to check whether at least one element in an array fits some description;
• every to check whether all entries in an array match a description;
• find to look for a value in an array

and so on. MDN link

-Xmn : the size of the heap for the young generation Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor" .

Good size is 33%

AFAIK, fragments cannot hold other fragments.

UPDATE

With current versions of the Android Support package -- or native fragments on API Level 17 and higher -- you can nest fragments, by means of getChildFragmentManager(). Note that this means that you need to use the Android Support package version of fragments on API Levels 11-16, because even though there is a native version of fragments on those devices, that version does not have getChildFragmentManager().

I found "gradle 1.11 com.android.tools.build:gradle:0.9.+" supports pre-build ndk now, you can just put the *.so in the dir src/main/jniLibs. when building gradle will package the ndk to the right place.

here is my project

Tip for MULTIPLE VIDEOS on a page: I recently solved an issue with no mp4 playback in Chrome or Firefox (played fine in IE) in a page with 16 videos in modals (bootstrap 3) after discovering the frame rates of all the videos must be identical. I had 6 videos at 25fps and 12 at 29.97fps... after rendering all to 25fps versions, everything runs smooth across all browsers.

I hit this error because I was specifying a label attribute in my geom (geom_text) but was specifying a color in the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# don't do this!
ggplot(df, aes(x=V6, y=V1, color=V1)) +
  geom_text(angle=45, label=df$V1, size=2)

To fix this, I just moved the label attribute out of the geom and into the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# do this!
ggplot(df, aes(x=V6, y=V1, color=V1, label=V1)) +
  geom_text(angle=45, size=2)

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

Just use the Form Paint method and draw every Picturebox on it, it allows transparency :

    private void frmGame_Paint(object sender, PaintEventArgs e)
    {
        DoubleBuffered = true;
        for (int i = 0; i < Controls.Count; i++)
            if (Controls[i].GetType() == typeof(PictureBox))
            {
                var p = Controls[i] as PictureBox;
                p.Visible = false;
                e.Graphics.DrawImage(p.Image, p.Left, p.Top, p.Width, p.Height);
            }
    }

 int x = 3;

 if(ceil(x) == x) {

  System.out.println("x is an integer");

 } else {

  System.out.println("x is not an integer");

 }

Using jQuery UI in combination with the excellent datetimepicker plugin from http://trentrichardson.com/examples/timepicker/

You can specify the dateFormat and timeFormat

$('#datepicker').datetimepicker({
    dateFormat: "yy-mm-dd",
    timeFormat:  "hh:mm:ss"
});

List<String> list = new ArrayList<>();

list.add("Hello");
list.add("Hello");
list.add("World");

Map<String, List<String>> collect = list.stream()
                                        .collect(Collectors.groupingBy(o -> o));
collect.entrySet()
       .forEach(e -> System.out.println(e.getKey() + " - " + e.getValue().size()));

Either in your admin.py or in a separate forms.py you can add a ModelForm class and then declare your extra fields inside that as you normally would. I've also given an example of how you might use these values in form.save():

from django import forms
from yourapp.models import YourModel


class YourModelForm(forms.ModelForm):

    extra_field = forms.CharField()

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)
        # ...do something with extra_field here...
        return super(YourModelForm, self).save(commit=commit)

    class Meta:
        model = YourModel

To have the extra fields appearing in the admin just:

1. edit your admin.py and set the form property to refer to the form you created above
2. include your new fields in your fields or fieldsets declaration

Like this:

class YourModelAdmin(admin.ModelAdmin):

    form = YourModelForm

    fieldsets = (
        (None, {
            'fields': ('name', 'description', 'extra_field',),
        }),
    )

UPDATE: In django 1.8 you need to add fields = '__all__' to the metaclass of YourModelForm.

I will quickly complement for cases where the header contains emojis, in that case it is simpler to just remove the emoji in the link of the reference. For example

# ? Title 2
....
[Take me to title 2](#-title-2)

There are some cases where this does not work for a weird reason, for example here in setup. The solution in that case is to include the whole code for the emoji as well.

This is the best way to do it, very simple.

$msg = "Hello this is a string";
$first_index_of_i = stripos($msg,'i');
$last_index_of_i = strripos($msg, 'i');

echo "First i : " . $first_index_of_i . PHP_EOL ."Last i : " . $last_index_of_i;

An Error "indicates serious problems that a reasonable application should not try to catch."

while

An Exception "indicates conditions that a reasonable application might want to catch."

Error along with RuntimeException & their subclasses are unchecked exceptions. All other Exception classes are checked exceptions.

Checked exceptions are generally those from which a program can recover & it might be a good idea to recover from such exceptions programmatically. Examples include FileNotFoundException, ParseException, etc. A programmer is expected to check for these exceptions by using the try-catch block or throw it back to the caller

On the other hand we have unchecked exceptions. These are those exceptions that might not happen if everything is in order, but they do occur. Examples include ArrayIndexOutOfBoundException, ClassCastException, etc. Many applications will use try-catch or throws clause for RuntimeExceptions & their subclasses but from the language perspective it is not required to do so. Do note that recovery from a RuntimeException is generally possible but the guys who designed the class/exception deemed it unnecessary for the end programmer to check for such exceptions.

Errors are also unchecked exception & the programmer is not required to do anything with these. In fact it is a bad idea to use a try-catch clause for Errors. Most often, recovery from an Error is not possible & the program should be allowed to terminate. Examples include OutOfMemoryError, StackOverflowError, etc.

Do note that although Errors are unchecked exceptions, we shouldn't try to deal with them, but it is ok to deal with RuntimeExceptions(also unchecked exceptions) in code. Checked exceptions should be handled by the code.

If the items are numerically ordered, use the key() function to determine the index of the current item and compare it to the length. You'd have to use next() or prev() to cycle through items in a while loop instead of a for loop:

$length = sizeOf($arr);
while (key(current($arr)) != $length-1) {
    $v = current($arr); doSomething($v); //do something if not the last item
    next($myArray); //set pointer to next item
}

I was facing the same issue. I tried both $http_my_custom_header and $sent_http_my_custom_header but it did not work for me.

Although solved this issue by using $upstream_http_my_custom_header.

Hope this work

I had the same issue because my file was called email.py. I renamed the file and the issue disappeared.

You mentioned sci-kit learn, so I want to share another solution.

sci-kit learn MinMaxScaler

In sci-kit learn, there is a API called MinMaxScaler which can customize the the value range as you like.

It also deal with NaN issues for us.

NaNs are treated as missing values: disregarded in fit, and maintained in transform. ... see reference [1]

Code sample

The code is simple, just type

# Let's say X_train is your input dataframe
from sklearn.preprocessing import MinMaxScaler
# call MinMaxScaler object
min_max_scaler = MinMaxScaler()
# feed in a numpy array
X_train_norm = min_max_scaler.fit_transform(X_train.values)
# wrap it up if you need a dataframe
df = pd.DataFrame(X_train_norm)

• [1] sklearn.preprocessing.MinMaxScaler

In eclipse, Go to Project->Properties->Java build Path->Order and Export. If you are using multiple JREs, try like jdk and ibm. Order should start with jdk and then IBM. This is how my issue was resolved.

There are two commands which will work in this situation,

root>git reset --hard HEAD~1

root>git push -f

One solution that was not mentioned earlier is to use a single link in a cell and some CSS to extend this link over the cells:

While I agree that the accepted answer is usually the best solution and definitely easier to use, I noticed no one displayed the proper usage of the iterator. So here is a quick example:

Iterator<Object> it = arrayList.iterator();
while(it.hasNext())
{
    Object obj = it.next();
    //Do something with obj
}

May be the private key itself is not present in the file.I was also faced the same issue but the problem is that there is no private key present in the file.

jQuery comes with the following options which could fulfil your need in this case:

append is used to add an element at the end of the parent div specified in the selector:

$('ul.tabs').append('<li>An element</li>');

prepend is used to add an element at the top/start of the parent div specified in the selector:

$('ul.tabs').prepend('<li>An element</li>');

insertAfter lets you insert an element of your selection next after an element you specify. Your created element will then be put in the DOM after the specified selector closing tag:

$('<li>An element</li>').insertAfter('ul.tabs>li:last');
will result in:
<li><a href="/user/edit"><span class="tab">Edit</span></a></li>
<li>An element</li>

insertBefore will do the opposite of the above:

$('<li>An element</li>').insertBefore('ul.tabs>li:last');
will result in:

Your best bet is to use a JDialog instead of a JFrame if you want to make the window modal. Check out details on the introduction of the Modality API in Java 6 for info. There is also a tutorial.

Here is some sample code which will display a JPanel panel in a JDialog which is modal to Frame parentFrame. Except for the constructor, this follows the same pattern as opening a JFrame.

final JDialog frame = new JDialog(parentFrame, frameTitle, true);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);

Edit: updated Modality API link & added tutorial link (nod to @spork for the bump).

Since you have a FULL backup, you can restore the backup to a different server as a database of the same name or to the same server with a different name.

Then you can just review the contents pre-update and write a SQL script to do the update.

I would like to cite a paragraph which describes the major difference between greedy algorithms and dynamic programming algorithms stated in the book Introduction to Algorithms (3rd edition) by Cormen, Chapter 15.3, page 381:

One major difference between greedy algorithms and dynamic programming is that instead of first finding optimal solutions to subproblems and then making an informed choice, greedy algorithms first make a greedy choice, the choice that looks best at the time, and then solve a resulting subproblem, without bothering to solve all possible related smaller subproblems.

Try this best way :

PreferenceConnector.java

import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;

public class PreferenceConnector {
    public static final String PREF_NAME = "ENUMERATOR_PREFERENCES";
    public static final String PREF_NAME_REMEMBER = "ENUMERATOR_REMEMBER";
    public static final int MODE = Context.MODE_PRIVATE;


    public static final String name = "name";


    public static void writeBoolean(Context context, String key, boolean value) {
        getEditor(context).putBoolean(key, value).commit();
    }

    public static boolean readBoolean(Context context, String key,
            boolean defValue) {
        return getPreferences(context).getBoolean(key, defValue);
    }

    public static void writeInteger(Context context, String key, int value) {
        getEditor(context).putInt(key, value).commit();

    }

    public static int readInteger(Context context, String key, int defValue) {
        return getPreferences(context).getInt(key, defValue);
    }

    public static void writeString(Context context, String key, String value) {
        getEditor(context).putString(key, value).commit();

    }

    public static String readString(Context context, String key, String defValue) {
        return getPreferences(context).getString(key, defValue);
    }

    public static void writeLong(Context context, String key, long value) {
        getEditor(context).putLong(key, value).commit();
    }

    public static long readLong(Context context, String key, long defValue) {
        return getPreferences(context).getLong(key, defValue);
    }

    public static SharedPreferences getPreferences(Context context) {
        return context.getSharedPreferences(PREF_NAME, MODE);
    }

    public static Editor getEditor(Context context) {
        return getPreferences(context).edit();
    }

}

Write the Value :

PreferenceConnector.writeString(this, PreferenceConnector.name,"Girish");

And Get value using :

String name= PreferenceConnector.readString(this, PreferenceConnector.name, "");

Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point

I've done like this and it works:

$('[name="tcol1"]')

https://api.jquery.com/attribute-equals-selector/

If you are looking to reduce the size using coding itself, you can follow this code in php.

<?php 
function compress($source, $destination, $quality) {

    $info = getimagesize($source);

    if ($info['mime'] == 'image/jpeg') 
        $image = imagecreatefromjpeg($source);

    elseif ($info['mime'] == 'image/gif') 
        $image = imagecreatefromgif($source);

    elseif ($info['mime'] == 'image/png') 
        $image = imagecreatefrompng($source);

    imagejpeg($image, $destination, $quality);

    return $destination;
}

$source_img = 'source.jpg';
$destination_img = 'destination .jpg';

$d = compress($source_img, $destination_img, 90);
?>

$d = compress($source_img, $destination_img, 90);

This is just a php function that passes the source image ( i.e., $source_img ), destination image ( $destination_img ) and quality for the image that will take to compress ( i.e., 90 ).

$info = getimagesize($source);

The getimagesize() function is used to find the size of any given image file and return the dimensions along with the file type.

See the following snippet, is this what you want?

body {
    background: silver;
    padding: 0 10px;
}

#content:after {
    height: 10px;
    display: block;
    width: 100px;
    background: #808080;
    border-right: 1px white;
    content: '';
}

#footer:before {
    display: block;
    content: '';
    background: silver;
    height: 10px;
    margin-top: -20px;
    margin-left: 101px;
}

#content {
    background: white;
}


#footer {
    padding-top: 10px;
    background: #404040;
}

p {
    padding: 100px;
    text-align: center;
}

#footer p {
    color: white;
}

<body>
    <div id="content"><p>#content</p></div>
    <div id="footer"><p>#footer</p></div>
</body>

JSFiddle

Just a proof of concept:

Look at the gist to see some annotations and stay up-to-date:

https://gist.github.com/yckart/c893d7db0f49b1ea4dfb

(function ($) {
  var methods = ['addClass', 'toggleClass', 'removeClass'];

  $.each(methods, function (index, method) {
    var originalMethod = $.fn[method];

    $.fn[method] = function () {
      var oldClass = this[0].className;
      var result = originalMethod.apply(this, arguments);
      var newClass = this[0].className;

      this.trigger(method, [oldClass, newClass]);

      return result;
    };
  });
}(window.jQuery || window.Zepto));

The usage is quite simple, just add a new listender on the node you want to observe and manipulate the classes as usually:

var $node = $('div')

// listen to class-manipulation
.on('addClass toggleClass removeClass', function (e, oldClass, newClass) {
  console.log('Changed from %s to %s due %s', oldClass, newClass, e.type);
})

// make some changes
.addClass('foo')
.removeClass('foo')
.toggleClass('foo');

You could split the problem up into two pieces:

1. Some kind of search algorithm that will enumerate possible strings in the grid.
2. A way of testing whether a string is a valid word.

Ideally, (2) should also include a way of testing whether a string is a prefix of a valid word – this will allow you to prune your search and save a whole heap of time.

Adam Rosenfield's Trie is a solution to (2). It's elegant and probably what your algorithms specialist would prefer, but with modern languages and modern computers, we can be a bit lazier. Also, as Kent suggests, we can reduce our dictionary size by discarding words that have letters not present in the grid. Here's some python:

def make_lookups(grid, fn='dict.txt'):
    # Make set of valid characters.
    chars = set()
    for word in grid:
        chars.update(word)

    words = set(x.strip() for x in open(fn) if set(x.strip()) <= chars)
    prefixes = set()
    for w in words:
        for i in range(len(w)+1):
            prefixes.add(w[:i])

    return words, prefixes

Wow; constant-time prefix testing. It takes a couple of seconds to load the dictionary you linked, but only a couple :-) (notice that words <= prefixes)

Now, for part (1), I'm inclined to think in terms of graphs. So I'll build a dictionary that looks something like this:

graph = { (x, y):set([(x0,y0), (x1,y1), (x2,y2)]), }

i.e. graph[(x, y)] is the set of coordinates that you can reach from position (x, y). I'll also add a dummy node None which will connect to everything.

Building it's a bit clumsy, because there's 8 possible positions and you have to do bounds checking. Here's some correspondingly-clumsy python code:

def make_graph(grid):
    root = None
    graph = { root:set() }
    chardict = { root:'' }

    for i, row in enumerate(grid):
        for j, char in enumerate(row):
            chardict[(i, j)] = char
            node = (i, j)
            children = set()
            graph[node] = children
            graph[root].add(node)
            add_children(node, children, grid)

    return graph, chardict

def add_children(node, children, grid):
    x0, y0 = node
    for i in [-1,0,1]:
        x = x0 + i
        if not (0 <= x < len(grid)):
            continue
        for j in [-1,0,1]:
            y = y0 + j
            if not (0 <= y < len(grid[0])) or (i == j == 0):
                continue

            children.add((x,y))

This code also builds up a dictionary mapping (x,y) to the corresponding character. This lets me turn a list of positions into a word:

def to_word(chardict, pos_list):
    return ''.join(chardict[x] for x in pos_list)

Finally, we do a depth-first search. The basic procedure is:

1. The search arrives at a particular node.
2. Check if the path so far could be part of a word. If not, don't explore this branch any further.
3. Check if the path so far is a word. If so, add to the list of results.
4. Explore all children not part of the path so far.

Python:

def find_words(graph, chardict, position, prefix, results, words, prefixes):
    """ Arguments:
      graph :: mapping (x,y) to set of reachable positions
      chardict :: mapping (x,y) to character
      position :: current position (x,y) -- equals prefix[-1]
      prefix :: list of positions in current string
      results :: set of words found
      words :: set of valid words in the dictionary
      prefixes :: set of valid words or prefixes thereof
    """
    word = to_word(chardict, prefix)

    if word not in prefixes:
        return

    if word in words:
        results.add(word)

    for child in graph[position]:
        if child not in prefix:
            find_words(graph, chardict, child, prefix+[child], results, words, prefixes)

Run the code as:

grid = ['fxie', 'amlo', 'ewbx', 'astu']
g, c = make_graph(grid)
w, p = make_lookups(grid)
res = set()
find_words(g, c, None, [], res, w, p)

and inspect res to see the answers. Here's a list of words found for your example, sorted by size:

 ['a', 'b', 'e', 'f', 'i', 'l', 'm', 'o', 's', 't',
 'u', 'w', 'x', 'ae', 'am', 'as', 'aw', 'ax', 'bo',
 'bu', 'ea', 'el', 'em', 'es', 'fa', 'ie', 'io', 'li',
 'lo', 'ma', 'me', 'mi', 'oe', 'ox', 'sa', 'se', 'st',
 'tu', 'ut', 'wa', 'we', 'xi', 'aes', 'ame', 'ami',
 'ase', 'ast', 'awa', 'awe', 'awl', 'blo', 'but', 'elb',
 'elm', 'fae', 'fam', 'lei', 'lie', 'lim', 'lob', 'lox',
 'mae', 'maw', 'mew', 'mil', 'mix', 'oil', 'olm', 'saw',
 'sea', 'sew', 'swa', 'tub', 'tux', 'twa', 'wae', 'was',
 'wax', 'wem', 'ambo', 'amil', 'amli', 'asem', 'axil',
 'axle', 'bleo', 'boil', 'bole', 'east', 'fame', 'limb',
 'lime', 'mesa', 'mewl', 'mile', 'milo', 'oime', 'sawt',
 'seam', 'seax', 'semi', 'stub', 'swam', 'twae', 'twas',
 'wame', 'wase', 'wast', 'weam', 'west', 'amble', 'awest',
 'axile', 'embox', 'limbo', 'limes', 'swami', 'embole',
 'famble', 'semble', 'wamble']

The code takes (literally) a couple of seconds to load the dictionary, but the rest is instant on my machine.

If you don't care about legacy browsers:

if ( bank_holidays.indexOf( '06/04/2012' ) > -1 )

if you do care about legacy browsers, there is a shim available on MDN. Otherwise, jQuery provides an equivalent function:

if ( $.inArray( '06/04/2012', bank_holidays ) > -1 )

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

I search about the same problem, but I wanted to store the array in a filed not to add the array as a tuple, so you may need the function serialize() and unserialize().

See this http://www.wpfasthelp.com/insert-php-array-into-mysql-database-table-row-field.htm

@Josh Lindsey already answered perfectly fine. But I want to add some information since I often use ssh.

Therefore just change:

git remote add origin [email protected]:/path/to/my_project.git

to:

git remote add origin ssh://[email protected]/path/to/my_project

Note that the colon between domain and path isn't there anymore.

I found this vimscript plugin is helpful for this situation.

Plugin 'vim-scripts/PreserveNoEOL'

Or read more at github

var xhr = new XMLHttpRequest();
xhr.open('POST', 'somewhere', true);
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.onload = function () {
    // do something to response
    console.log(this.responseText);
};
xhr.send('user=person&pwd=password&organization=place&requiredkey=key');

Or if you can count on browser support you could use FormData:

var data = new FormData();
data.append('user', 'person');
data.append('pwd', 'password');
data.append('organization', 'place');
data.append('requiredkey', 'key');

var xhr = new XMLHttpRequest();
xhr.open('POST', 'somewhere', true);
xhr.onload = function () {
    // do something to response
    console.log(this.responseText);
};
xhr.send(data);

In my case, I unload the project, then:

1. Opened myProject.csproj and update the ToolsVersion="4.0" to ToolsVersion="12.0"(I'm using vs 2017)(using Paulus's answer https://stackoverflow.com/a/64552201/1594487).

2. Deleted following lines from the myProject.csproj:

   <Import Project="..\packages\EntityFramework.6.4.0\build\EntityFramework.props" Condition="Exists('..\packages\EntityFramework.6.4.0\build\EntityFramework.props')" />
   <Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />
   

And the problem solved.

Carry Flag is a flag set when:

a) two unsigned numbers were added and the result is larger than "capacity" of register where it is saved. Ex: we wanna add two 8 bit numbers and save result in 8 bit register. In your example: 255 + 9 = 264 which is more that 8 bit register can store. So the value "8" will be saved there (264 & 255 = 8) and CF flag will be set.

b) two unsigned numbers were subtracted and we subtracted the bigger one from the smaller one. Ex: 1-2 will give you 255 in result and CF flag will be set.

Auxiliary Flag is used as CF but when working with BCD. So AF will be set when we have overflow or underflow on in BCD calculations. For example: considering 8 bit ALU unit, Auxiliary flag is set when there is carry from 3rd bit to 4th bit i.e. carry from lower nibble to higher nibble. (Wiki link)

Overflow Flag is used as CF but when we work on signed numbers. Ex we wanna add two 8 bit signed numbers: 127 + 2. the result is 129 but it is too much for 8bit signed number, so OF will be set. Similar when the result is too small like -128 - 1 = -129 which is out of scope for 8 bit signed numbers.

You can read more about flags on wikipedia

Try using Math.floor.

When interviewing recently, I was often asked to implement a data structure, usually LinkedList or HashMap. Both of these are easy enough to be doable in a short time, and difficult enough to eliminate the clueless.

String[] arr = {"foo", "bar"};

If you pass a string array to a method, do:

myFunc(arr);

or do:

myFunc(new String[] {"foo", "bar"});

For a file:

if exist yourfilename (
  echo Yes 
) else (
  echo No
)

Replace yourfilename with the name of your file.

For a directory:

if exist yourfoldername\ (
  echo Yes 
) else (
  echo No
)

Replace yourfoldername with the name of your folder.

A trailing backslash (\) seems to be enough to distinguish between directories and ordinary files.

DateTime.now.strftime("%Q")

Example usage:

>> DateTime.now.strftime("%Q")
=> "1541433332357"

>> DateTime.now.strftime("%Q").to_i
=> 1541433332357

In the constructor of the Form or UserControl holding the TextBox write

SetStyle(ControlStyles.Selectable, false);

After the InitializeComponent(); Source: https://stackoverflow.com/a/4811938/5750078

Example:

public partial class Main : UserControl
{

    public Main()
    {
        InitializeComponent();
        SetStyle(ControlStyles.Selectable, false);
    }

try

echo "$".money_format('%i',$price);

output will be

$1.06

Easy way:

#include <time.h>
#include <stdio.h>
#include <string.h>

int main(void)
{
    time_t mytime = time(NULL);
    char * time_str = ctime(&mytime);
    time_str[strlen(time_str)-1] = '\0';
    printf("Current Time : %s\n", time_str);

    return 0;
}

Two options (at least):

1. Add the commons-logging jar to your file by copying it into a local folder.

Note: linking the jar can lead to problems with the server and maybe the reason why it's added to the build path but not solving the server startup problem.

So don't point the jar to an external folder.

OR...

2. If you really don't want to add it locally because you're sharing the jar between projects, then...

If you're using a tc server instance, then you need to add the jar as an external jar to the server instance run configurations.

go to run as, run configurations..., {your tc server instance}, and then the Class Path tab.

Then add the commons-logging jar.

My reading of the docs is that HttpConnection itself is not treated as thread safe, and hence MultiThreadedHttpConnectionManager provides a reusable pool of HttpConnections, you have a single MultiThreadedHttpConnectionManager shared by all threads and initialised exactly once. So you need a couple of small refinements to option A.

MultiThreadedHttpConnectionManager connman = new MultiThreadedHttpConnectionManag

Then each thread should be using the sequence for every request, getting a conection from the pool and putting it back on completion of its work - using a finally block may be good. You should also code for the possibility that the pool has no available connections and process the timeout exception.

HttpConnection connection = null
try {
    connection = connman.getConnectionWithTimeout(
                        HostConfiguration hostConfiguration, long timeout) 
    // work
} catch (/*etc*/) {/*etc*/} finally{
    if ( connection != null )
        connman.releaseConnection(connection);
}

As you are using a pool of connections you won't actually be closing the connections and so this should not hit the TIME_WAIT problem. This approach does assuume that each thread doesn't hang on to the connection for long. Note that conman itself is left open.

CONTAINS is for a Full Text Indexed field - if not, then use LIKE

I was asking the same question just now after a quick google I found that There is a pair class in .NET except its in the System.Web.UI ^ ~ ^ (http://msdn.microsoft.com/en-us/library/system.web.ui.pair.aspx) goodness knows why they put it there instead of the collections framework

plt.hist(hmag, 30, range=[6.5, 12.5], facecolor='gray', align='mid')

If you are looking for ad-hoc items rather than something that you would put into SSIS. From within SSMS simply highlight the results grid, copy, then paste into excel, it isn't elegant, but works. Then you can save as native .xls rather than .csv

By using Python Interactive Debugger 'pdb'

First step is to make the Python interpreter to enter into the debugging mode.

A. From the Command Line

Most straight forward way, running from command line, of python interpreter

$ python -m pdb scriptName.py
> .../pdb_script.py(7)<module>()
-> """
(Pdb)

B. Within the Interpreter

While developing early versions of modules and to experiment it more iteratively.

$ python
Python 2.7 (r27:82508, Jul  3 2010, 21:12:11)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pdb_script
>>> import pdb
>>> pdb.run('pdb_script.MyObj(5).go()')
> <string>(1)<module>()
(Pdb)

C. From Within Your Program

For a big project and long-running module, can start the debugging from inside the program using import pdb and set_trace() like this :

#!/usr/bin/env python
# encoding: utf-8
#

import pdb

class MyObj(object):
    count = 5
    def __init__(self):
        self.count= 9

    def go(self):
        for i in range(self.count):
            pdb.set_trace()
            print i
        return

if __name__ == '__main__':
    MyObj(5).go()

Step-by-Step debugging to go into more internal

1. Execute the next statement… with “n” (next)

2. Repeating the last debugging command… with ENTER

3. Quitting it all… with “q” (quit)

4. Printing the value of variables… with “p” (print)

   a) p a

5. Turning off the (Pdb) prompt… with “c” (continue)

6. Seeing where you are… with “l” (list)

7. Stepping into subroutines… with “s” (step into)

8. Continuing… but just to the end of the current subroutine… with “r” (return)

9. Assign a new value

   a) !b = "B"

10. Set a breakpoint

    a) break linenumber

    b) break functionname

    c) break filename:linenumber

11. Temporary breakpoint

    a) tbreak linenumber

12. Conditional breakpoint

    a) break linenumber, condition

Note:**All these commands should be execute from **pdb

Visual Studio has got now integrated support for range checking and type checking :-

Try this :- For RANGE CHECKING Before validating/checking for a particular range of numbers Switch on to design view from markup view .Then :-

View>Toolbox>Validation

Now Drag on RangeValidator to your design page where you want to show the error message(ofcourse if user is inputting out of range value) now click on your RangeValidator control . Right click and select properties . In the Properties window (It is usually opened below solution bar) select on ERROR MESSAGE . Write :-

Number must be in range.

Now select on Control to validate and select your TextboxID (or write it anyways) from the drop down.Locate Type in the property bar itself and select down Integer.
Just above it you will find maximum and minimum value .Type in your desired number .

For Type checking (without any Range)
Before validating/checking for a particular range of numbers Switch on to design view from markup view .Then :-

View>Toolbox>Validation

Now Drag on CompareValidator to your design page where you want to show the error message(ofcourse if user is inputting some text in it). now click on your CompareValidator control . Right click and select properties . In the Properties window (It is usually opened below solution bar) select on ERROR MESSAGE . Write:-

Value must be a number .

Now locate ControltoValidate option and write your controlID name in it(alternatively you can also select from drop down).Locate the Operator option and write DataTypeCheck(alternatively you can also select from drop down)in it .Again locate the Type option and write Integer in it .

That's sit.

Alternatively you can write the following code in your aspx page :- <%--to validate without any range--%>

Parse that string into a Date object:

var myDate = new Date('10/11/1955 10:40:50 AM');

Then use the usual methods to get the date's day of month (getDate) / month (getMonth) / year (getFullYear).

var noTime = new Date(myDate.getFullYear(), myDate.getMonth(), myDate.getDate());

The IEnumerable and IEnumerator Interfaces

To begin examining the process of implementing existing .NET interfaces, let’s first look at the role of IEnumerable and IEnumerator. Recall that C# supports a keyword named foreach that allows you to iterate over the contents of any array type:

// Iterate over an array of items.
int[] myArrayOfInts = {10, 20, 30, 40};
foreach(int i in myArrayOfInts)
{
   Console.WriteLine(i);
}

While it might seem that only array types can make use of this construct, the truth of the matter is any type supporting a method named GetEnumerator() can be evaluated by the foreach construct.To illustrate, follow me!

Suppose we have a Garage class:

// Garage contains a set of Car objects.
public class Garage
{
   private Car[] carArray = new Car[4];
   // Fill with some Car objects upon startup.
   public Garage()
   {
      carArray[0] = new Car("Rusty", 30);
      carArray[1] = new Car("Clunker", 55);
      carArray[2] = new Car("Zippy", 30);
      carArray[3] = new Car("Fred", 30);
   }
}

Ideally, it would be convenient to iterate over the Garage object’s subitems using the foreach construct, just like an array of data values:

// This seems reasonable ...
public class Program
{
   static void Main(string[] args)
   {
      Console.WriteLine("***** Fun with IEnumerable / IEnumerator *****\n");
      Garage carLot = new Garage();
      // Hand over each car in the collection?
      foreach (Car c in carLot)
      {
         Console.WriteLine("{0} is going {1} MPH",
         c.PetName, c.CurrentSpeed);
      }
      Console.ReadLine();
   }
}

Sadly, the compiler informs you that the Garage class does not implement a method named GetEnumerator(). This method is formalized by the IEnumerable interface, which is found lurking within the System.Collections namespace. Classes or structures that support this behavior advertise that they are able to expose contained subitems to the caller (in this example, the foreach keyword itself). Here is the definition of this standard .NET interface:

// This interface informs the caller
// that the object's subitems can be enumerated.
public interface IEnumerable
{
   IEnumerator GetEnumerator();
}

As you can see, the GetEnumerator() method returns a reference to yet another interface named System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:

// This interface allows the caller to
// obtain a container's subitems.
public interface IEnumerator
{
   bool MoveNext (); // Advance the internal position of the cursor.
   object Current { get;} // Get the current item (read-only property).
   void Reset (); // Reset the cursor before the first member.
}

If you want to update the Garage type to support these interfaces, you could take the long road and implement each method manually. While you are certainly free to provide customized versions of GetEnumerator(), MoveNext(), Current, and Reset(), there is a simpler way. As the System.Array type (as well as many other collection classes) already implements IEnumerable and IEnumerator, you can simply delegate the request to the System.Array as follows:

using System.Collections;
...
public class Garage : IEnumerable
{
   // System.Array already implements IEnumerator!
   private Car[] carArray = new Car[4];
   public Garage()
   {
      carArray[0] = new Car("FeeFee", 200);
      carArray[1] = new Car("Clunker", 90);
      carArray[2] = new Car("Zippy", 30);
      carArray[3] = new Car("Fred", 30);
   }
   public IEnumerator GetEnumerator()
   {
      // Return the array object's IEnumerator.
      return carArray.GetEnumerator();
   }
}

After you have updated your Garage type, you can safely use the type within the C# foreach construct. Furthermore, given that the GetEnumerator() method has been defined publicly, the object user could also interact with the IEnumerator type:

// Manually work with IEnumerator.
IEnumerator i = carLot.GetEnumerator();
i.MoveNext();
Car myCar = (Car)i.Current;
Console.WriteLine("{0} is going {1} MPH", myCar.PetName, myCar.CurrentSpeed);

However, if you prefer to hide the functionality of IEnumerable from the object level, simply make use of explicit interface implementation:

IEnumerator IEnumerable.GetEnumerator()
{
  // Return the array object's IEnumerator.
  return carArray.GetEnumerator();
}

By doing so, the casual object user will not find the Garage’s GetEnumerator() method, while the foreach construct will obtain the interface in the background when necessary.

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

You can't download the file directly via ajax.

You can put a link on the page with the URL to your file (returned from the ajax call) or another way is to use a hidden iframe and set the URL of the source of that iframe dynamically. This way you can download the file without refreshing the page.

Here is the code

$.ajax({
    url : "yourURL.php",
    type : "GET",
    success : function(data) {
        $("#iframeID").attr('src', 'downloadFileURL');
    }
});

For me, this issue was caused in my build system (Travis CI) by doing something kind of dumb in my .travis.yml file. In effect, I was calling npm install before nvm use 0.12, and this was causing node-sass to be built for 0.10 instead of 0.12. My solution was simply moving nvm use out of the .travis.yml file’s before_script section to before the npm install command, which was in the before_install section.

In your case, it is likely that whatever process you are starting with gulp is using a different version of node (than what you would expect).

same problem happened to me, From this

I have faced the same issue, to solve it:

1- delete (or move) the projects folder (AndroidStudioProjects).

2- Run the Android-Studio (a WELCOME screen will started).

3- From Welcome Screen choose, "Configure -> Project Defaults -> Project Structure)

4- Under Platform Settings choose SDKs.

5- Select Android SDK -> right_click delete.

6- Right_click -> New Sdk -> Android SDK -> choose your SDK dir -> then OK.

7- Choose the Build target -> apply -> OK. enjoy

Under my Linux installation, it's here: /var/lib/postgresql/8.x/

You can change it with initdb -D "c:/mydb/"

let pattern = /^(?=.*[0-9])(?=.*[!@#$%^&*])(?=.*[a-z])(?=.*[A-Z])[a-zA-Z0-9!@#$%^&*]{6,16}$/;

//following will give you the result as true(if the password contains Capital, small letter, number and special character) or false based on the string format

let reee =pattern .test("helLo123@");   //true as it contains all the above

You can't. "" is the literal for a string, which contains no characters. It does not contain the "empty character" (whatever you mean by that).

If you are on Ubuntu, run:

 sudo apt-get install php-mysqlnd

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

(using the same example as the guy above)

from matplotlib import pyplot
import numpy
a = numpy.arange(int(1e3))
fig = pyplot.Figure()
ax  = fig.add_subplot(1, 1, 1)
lines = ax.plot(a)

for i, line in enumerate(ax.lines):
    ax.lines.pop(i)
    line.remove()

The correct (lldb) command is: Realm.Configuration.defaultConfiguration.path.

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

You could use this to wrap urllib2:

def URLRequest(url, params, method="GET"):
    if method == "POST":
        return urllib2.Request(url, data=urllib.urlencode(params))
    else:
        return urllib2.Request(url + "?" + urllib.urlencode(params))

That will return a Request object that has result data and response codes.

What about inv?

e.g.: my_inverse_array = inv(my_array)

The most simple way is to use Record type Record<number, productDetails >

interface productDetails {
   productId : number , 
   price : number , 
   discount : number
};

const myVar : Record<number, productDetails> = {
   1: {
       productId : number , 
       price : number , 
       discount : number
   }
}

JavaScript

function playAudio(url) {
  new Audio(url).play();
}

HTML

<img src="image.png" onclick="playAudio('mysound.mp3')">

Supported in most modern browsers and easy to embed into HTML elements.

You can create a new row with $ in your data frame corresponding to the Means

DF$Mean <- rowMeans(DF[,2:4])

In IE 8, cookies (verified only against localhost) are shared between ports. In FF 10, they are not.

I've posted this answer so that readers will have at least one concrete option for testing each scenario.

if(['true', 'yes', '1'].includes(single_value)) {
    return  true;   
}
else if(['false', 'no', '0'].includes(single_value)) {
    return  false;  
}

if you have a string

Since Python 2.7 there's the timedelta.total_seconds() method. So, to get the elapsed milliseconds:

>>> import datetime
>>> a = datetime.datetime.now()
>>> b = datetime.datetime.now()
>>> delta = b - a
>>> print delta
0:00:05.077263
>>> int(delta.total_seconds() * 1000) # milliseconds
5077

This question may help: How to pass variable by reference in javascript? Read data from ActiveX function which returns more than one value

To summarise, Javascript primitive types are always passed by value, whereas the values inside objects are passed by reference (thanks to commenters for pointing out my oversight). So to get round this, you have to put your integer inside an object:

var myobj = {x:0};_x000D_
_x000D_
function a(obj)_x000D_
{_x000D_
    obj.x++;_x000D_
}_x000D_
_x000D_
a(myobj);_x000D_
alert(myobj.x); // returns 1_x000D_
_x000D_
  

If SDK folder is present in system, one can find in C:\Users\%USERNAME%\AppData\Local\Android

If Android/SDK folder is not found Once done with downloading and installing Android Studio, you need to launch studio. On launching Android studio for the first time, we get option to download further more components, in that we have SDK. On downloading components one can find SDK under Appdata (C:\Users\%USERNAME%\AppData\Local\Android)

The answer was given already by either Sivasubramaniam Arunachalam or ch3ka.

dicttest={}
dicttest['ligne1']={'ligne1.1':'test','ligne1.2':'test8'}
%timeit dicttest['ligne1']['ligne1.1']
%timeit dicttest.get('ligne1').get('ligne1.1')

gives us :

112 ns ± 29.7 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

235 ns ± 9.82 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

Hi I know this topic is old but there is a much better way to differentiate an Array in Node.js from any other Object have a look at the docs.

var util = require('util');

util.isArray([]); // true
util.isArray({}); // false

var obj = {};
typeof obj === "Object" // true

Be careful, with COUNT your first item in the bag must not be null. Else you can use the function COUNT_STAR to count all rows.

No, you can use only some escape sequences - \n for example (maybe only this one).

I was getting this exception when debugging in PyCharm, given that no breakpoint was being hit. To prevent it, I added a breakpoint just after the with block, and then it stopped happening.

The precision of float is 7 digits. If you want to keep the whole lot, you need to use the double type that keeps 15-16 digits. Regarding formatting, look at a post about formatting doubles. And you need to worry about decimal separators in C#.

I was looking for shortest way to draw an 1px line, as whole load of separated CSS is not the fastest or shortest solution.

Up to HTML5, the WAS a shorter way for 1px hr: <hr noshade> but.. The noshade attribute of <hr> is not supported in HTML5. Use CSS instead. (nor other attibutes used before, as size, width, align)...

Now, this one is quite tricky, but works well if most simple 1px hr needed:

Variation 1, BLACK hr: (best solution for black)

<hr style="border-bottom: 0px">

Output: FF, Opera - black / Safari - dark gray

Variation 2, GRAY hr (shortest!):

<hr style="border-top: 0px">

Output: Opera - dark gray / FF - gray / Safari - light gray

<hr style="border: none; border-bottom: 1px solid red;">

Output: Opera / FF / Safari : 1px red.

Nowadays (2016) in Chrome Dev Tools console, you can quickly execute this function below to show all event listeners that have been attached to an element.

getEventListeners(document.querySelector('your-element-selector'));

Faced the same problem as OP:

• Tomcat returned response when accessing directly via SOAP UI
• Didn't load html files
• When used Apache properties mentioned by the previous answer, web-page appeared but AngularJS couldn't get HTTP response

Tomcat SSL certificate was expired while a browser showed it as secure - Apache certificate was far from expiration. Updating Tomcat KeyStore file solved the problem.

Here is the solution for that find the UUID of box

vboxmanage list hdds

then delete by

As an addition to user1471935's suggestion:

To instantiate a generic class by using a constructor with one or more parameters, you can now use the Activator class.

T instance = Activator.CreateInstance(typeof(T), new object[] {...}) 

The list of objects are the parameters you want to supply. According to Microsoft:

CreateInstance [...] creates an instance of the specified type using the constructor that best matches the specified parameters.

There's also a generic version of CreateInstance (CreateInstance<T>()) but that one also does not allow you to supply constructor parameters.

Apparently, org.json.simple.JSONArray implements a raw Iterator. This means that each element is considered to be an Object. You can try to cast:

for(Object o: arr){
    if ( o instanceof JSONObject ) {
        parse((JSONObject)o);
    }
}

This is how things were done back in Java 1.4 and earlier.

Path.GetFullPath gives below exceptions only

ArgumentException path is a zero-length string, contains only white space, or contains one or more of the invalid characters defined in GetInvalidPathChars. -or- The system could not retrieve the absolute path.

SecurityException The caller does not have the required permissions.

ArgumentNullException path is null.

NotSupportedException path contains a colon (":") that is not part of a volume identifier (for example, "c:\").

You can fix broken serialize string using following function, with multibyte character handling.

function repairSerializeString($value)
{

    $regex = '/s:([0-9]+):"(.*?)"/';

    return preg_replace_callback(
        $regex, function($match) {
            return "s:".mb_strlen($match[2]).":\"".$match[2]."\""; 
        },
        $value
    );
}

In my case alter column was not working so one can use 'Modify' command, like:

alter table [table_name] MODIFY column [column_name] varchar(1200);

Here is the full list of YouTube embedded player parameters.

Relevant info:

autoplay (supported players: AS3, AS2, HTML5) Values: 0 or 1. Default is 0. Sets whether or not the initial video will autoplay when the player loads.

loop (supported players: AS3, HTML5) Values: 0 or 1. Default is 0. In the case of a single video player, a setting of 1 will cause the player to play the initial video again and again. In the case of a playlist player (or custom player), the player will play the entire playlist and then start again at the first video.

Note: This parameter has limited support in the AS3 player and in IFrame embeds, which could load either the AS3 or HTML5 player. Currently, the loop parameter only works in the AS3 player when used in conjunction with the playlist parameter. To loop a single video, set the loop parameter value to 1 and set the playlist parameter value to the same video ID already specified in the Player API URL:

http://www.youtube.com/v/VIDEO_ID?version=3&loop=1&playlist=VIDEO_ID

Use the URL above in your embed code (append other parameters too).

If you're using the resource routes, then in the HTML body of the form, you can use method_field helper like this:

<form>
  {{ csrf_field() }}
  {{ method_field('PUT') }}
  <!-- ... -->
</form>

It will create hidden form input with method type, that is correctly interpereted by Laravel 5.5+.

Since Laravel 5.6 you can use following Blade directives in the templates:

<form>
  @method('put')
  @csrf
  <!-- ... -->
</form>

Hope this might help someone in the future.

All solution are complicated and of jscript. Here is the simplest version:

var IsChildWindow=false;

function ParentClick()
{
    if(IsChildWindow==true)
    {
        IsChildWindow==false;
        return;
    }
    //do ur work here   
}


function ChildClick()
{
    IsChildWindow=true;
    //Do ur work here    
}

Basic Authentication use base 64 Encoding for generating cryptographic string which contains the information of username and password.

Digest Access Authentication uses the hashing methodologies to generate the cryptographic result

I arrived at a different solution, which is to get the IDs for the last post within each group, then select from the messages table using the result from the first query as the argument for a WHERE x IN construct:

SELECT id, name, other_columns
FROM messages
WHERE id IN (
    SELECT MAX(id)
    FROM messages
    GROUP BY name
);

I don't know how this performs compared to some of the other solutions, but it worked spectacularly for my table with 3+ million rows. (4 second execution with 1200+ results)

This should work both on MySQL and SQL Server.

You can try using string replace:

string = string.replace('\r', '').replace('\n', '')

I made a plugin for the simulator that does just this. You can find it at my blog.

It actually records the screen. It does not rely on another screen capture program like iShowU.

It will install icons for the default apps and change the carrier text to look like a real device.

Or you could do it like this.

var palindrome = word => word == word.split('').reverse().join('')

Here is a version inspired by this thread that more closely mimics distutils.file_util.copy_file.

updateonly is a bool if True, will only copy files with modified dates newer than existing files in dst unless listed in forceupdate which will copy regardless.

ignore and forceupdate expect lists of filenames or folder/filenames relative to src and accept Unix-style wildcards similar to glob or fnmatch.

The function returns a list of files copied (or would be copied if dryrun if True).

During runtime your application is unable to find the jar.

Taken from this answer by Jared:

It is important to keep two different exceptions straight in our head in this case:

1. java.lang.ClassNotFoundException This an Exception, it indicates that the class was not found on the classpath. This indicates that we were trying to load the class definition, and the class did not exist on the classpath.

2. java.lang.NoClassDefFoundError This is Error, it indicates that the JVM looked in its internal class definition data structure for the definition of a class and did not find it. This is different than saying that it could not be loaded from the classpath. Usually this indicates that we previously attempted to load a class from the classpath, but it failed for some reason - now we're trying again, but we're not even going to try to load it, because we failed loading it earlier. The earlier failure could be a ClassNotFoundException or an ExceptionInInitializerError (indicating a failure in the static initialization block) or any number of other problems. The point is, a NoClassDefFoundError is not necessarily a classpath problem.

Ruby automatically converts integers to a large integer class when they overflow, so there's (practically) no limit to how big they can be.

If you are looking for the machine's size, i.e. 64- or 32-bit, I found this trick at ruby-forum.com:

machine_bytes = ['foo'].pack('p').size
machine_bits = machine_bytes * 8
machine_max_signed = 2**(machine_bits-1) - 1
machine_max_unsigned = 2**machine_bits - 1

If you are looking for the size of Fixnum objects (integers small enough to store in a single machine word), you can call 0.size to get the number of bytes. I would guess it should be 4 on 32-bit builds, but I can't test that right now. Also, the largest Fixnum is apparently 2**30 - 1 (or 2**62 - 1), because one bit is used to mark it as an integer instead of an object reference.

In my case I got the error on output parameter even though I was setting it correctly on C# side I figured out I forgot to give a default value to output parameter on the stored procedure

ALTER PROCEDURE [dbo].[test]

                @UserID int,
                @ReturnValue int = 0 output --Previously I had @ReturnValue int output
)

If you use the following CSS

<link href="~/Content/common/bootstrap.css" rel="stylesheet" type="text/css"    />
<link href="~/Content/common/bootstrap.min.css" rel="stylesheet" type="text/css" />
<link href="~/Content/common/site.css" rel="stylesheet" type="text/css" />

just change it into the following style by adding media="screen"

<link href="~/Content/common/bootstrap.css" rel="stylesheet" **media="screen"** type="text/css" />
<link href="~/Content/common/bootstrap.min.css" rel="stylesheet" **media="screen"** type="text/css" />
<link href="~/Content/common/site.css" rel="stylesheet" **media="screen"** type="text/css" />

I think it will work.

the former answers like

    @media print {
  a[href]:after {
    content: none !important;
  }
}

were not worked well in the chrome browse.

There will definitely be an open bracket which caused the error.

I'd suggest that you open the page in Firefox, then open Firebug and check the console – it'll show the missing symbol.

Just in case anyone runs into this in an environment where they cannot set node properties directly (in my case a build tool):

NODE_OPTIONS="--max-old-space-size=4096" node ...

You can set the node options using an environment variable if you cannot pass them on the command line.

Simplest way is to use the dot operator in place of source, which is the sh equivalent of the bash source command:

Instead of:

RUN source /usr/local/bin/virtualenvwrapper.sh

Use:

RUN . /usr/local/bin/virtualenvwrapper.sh

How to get the height of the navigation bar and status bar. This code works for me on some Huawei devices and Samsung devices. Egis's solution above is good, however, it is still incorrect on some devices. So, I improved it.

This is code to get the height of status bar

private fun getStatusBarHeight(resources: Resources): Int {
        var result = 0
        val resourceId = resources.getIdentifier("status_bar_height", "dimen", "android")
        if (resourceId > 0) {
            result = resources.getDimensionPixelSize(resourceId)
        }
        return result
    }

This method always returns the height of navigation bar even when the navigation bar is hidden.

private fun getNavigationBarHeight(resources: Resources): Int {
    val resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android")
    return if (resourceId > 0) {
        resources.getDimensionPixelSize(resourceId)
    } else 0
}

NOTE: on Samsung A70, this method returns the height of the status bar + height of the navigation bar. On other devices (Huawei), it only returns the height of the Navigation bar and returns 0 when the navigation bar is hidden.

private fun getNavigationBarHeight(): Int {
        val display = activity?.windowManager?.defaultDisplay
        return if (display == null) {
            0
        } else {
            val realMetrics = DisplayMetrics()
            display.getRealMetrics(realMetrics)
            val metrics = DisplayMetrics()
            display.getMetrics(metrics)
            realMetrics.heightPixels - metrics.heightPixels
        }
    }

This is code to get height of navigation bar and status bar

val metrics = DisplayMetrics()
        activity?.windowManager?.defaultDisplay?.getRealMetrics(metrics)

        //resources is got from activity

        //NOTE: on SamSung A70, this height = height of status bar + height of Navigation bar
        //On other devices (Huawei), this height = height of Navigation bar
        val navigationBarHeightOrNavigationBarPlusStatusBarHeight = getNavigationBarHeight()

        val statusBarHeight = getStatusBarHeight(resources)
        //The method will always return the height of navigation bar even when the navigation bar was hidden.
        val realNavigationBarHeight = getNavigationBarHeight(resources)

        val realHeightOfStatusBarAndNavigationBar =
                if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == 0 || navigationBarHeightOrNavigationBarPlusStatusBarHeight < statusBarHeight) {
                    //Huawei: navigation bar is hidden
                    statusBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == realNavigationBarHeight) {
                    //Huawei: navigation bar is visible
                    statusBarHeight + realNavigationBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight < realNavigationBarHeight) {
                    //SamSung A70: navigation bar is still visible but it only displays as a under line
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight = navigationBarHeight'(under line) + statusBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                } else {
                    //SamSung A70: navigation bar is visible
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight == statusBarHeight + realNavigationBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                }

My biggest concern with not checking folder node_modules into Git is that 10 years down the road, when your production application is still in use, npm may not be around. Or npm might become corrupted; or the maintainers might decide to remove the library that you rely on from their repository; or the version you use might be trimmed out.

This can be mitigated with repository managers like Maven, because you can always use your own local Nexus (Sonatype) or Artifactory to maintain a mirror with the packages that you use. As far as I understand, such a system doesn't exist for npm. The same goes for client-side library managers like Bower and Jam.js.

If you've committed the files to your own Git repository, then you can update them when you like, and you have the comfort of repeatable builds and the knowledge that your application won't break because of some third-party action.

The '::' is for static members.

ProgressBar color can be changed as follows:

/res/values/colors.xml

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

</resources>

/res/values/styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorAccent">@color/colorAccent</item>
</style> 

onCreate:

progressBar = (ProgressBar) findViewById(R.id.progressBar);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
    Drawable drawable = progressBar.getIndeterminateDrawable().mutate();
    drawable.setColorFilter(ContextCompat.getColor(this, R.color.colorAccent), PorterDuff.Mode.SRC_IN);
    progressBar.setIndeterminateDrawable(drawable);
}

You won't see a simple answer because there isn't one.

First, Unicode doesn't contain "every character from every language", although it sure does try.

Unicode itself is a mapping, it defines codepoints and a codepoint is a number, associated with usually a character. I say usually because there are concepts like combining characters. You may be familiar with things like accents, or umlauts. Those can be used with another character, such as an a or a u to create a new logical character. A character therefore can consist of 1 or more codepoints.

To be useful in computing systems we need to choose a representation for this information. Those are the various unicode encodings, such as utf-8, utf-16le, utf-32 etc. They are distinguished largely by the size of of their codeunits. UTF-32 is the simplest encoding, it has a codeunit that is 32bits, which means an individual codepoint fits comfortably into a codeunit. The other encodings will have situations where a codepoint will need multiple codeunits, or that particular codepoint can't be represented in the encoding at all (this is a problem for instance with UCS-2).

Because of the flexibility of combining characters, even within a given encoding the number of bytes per character can vary depending on the character and the normalization form. This is a protocol for dealing with characters which have more than one representation (you can say "an 'a' with an accent" which is 2 codepoints, one of which is a combining char or "accented 'a'" which is one codepoint).

Afer looking at the source, for WP7 Hammock doesn't actually use Json.Net for JSON parsing. Instead it uses it's own parser which doesn't cope with custom types very well.

If using Json.Net directly it is possible to deserialize to a strongly typed collection inside a wrapper object.

var response = @"
    {
        ""data"": [
            {
                ""name"": ""A Jones"",
                ""id"": ""500015763""
            },
            {
                ""name"": ""B Smith"",
                ""id"": ""504986213""
            },
            {
                ""name"": ""C Brown"",
                ""id"": ""509034361""
            }
        ]
    }
";

var des = (MyClass)Newtonsoft.Json.JsonConvert.DeserializeObject(response, typeof(MyClass));

return des.data.Count.ToString();

and with:

public class MyClass
{
    public List<User> data { get; set; }
}

public class User
{
    public string name { get; set; }
    public string id { get; set; }
}

Having to create the extra object with the data property is annoying but that's a consequence of the way the JSON formatted object is constructed.

Documentation: Serializing and Deserializing JSON

If you want to use Unix shell commands on Windows, you can use Windows Powershell, which includes both Windows and Unix commands as aliases. You can find more info on it in the documentation.

PowerShell supports aliases to refer to commands by alternate names. Aliasing allows users with experience in other shells to use common command names that they already know for similar operations in PowerShell.

The PowerShell equivalents may not produce identical results. However, the results are close enough that users can do work without knowing the PowerShell command name.

This can be achieved using command cgo.

In essence 'If the import of "C" is immediately preceded by a comment, that comment, called the preamble, is used as a header when compiling the C parts of the package. For example:'
source:https://golang.org/cmd/cgo/

// #include <stdio.h>
// #include <errno.h>
import "C"

Here is a solution that works best for a single line of text.

It can also work for multi-lined text with some tweaking if the number of lines is known.

.testimonialText {
    font-size: 1em; /* Set a font size */
}
.testimonialText:before { /* Add a pseudo element */
    content: "";
    display: block;
    height: 50%;
    margin-top: -0.5em; /* Half of the font size */
}

Here is a JSFiddle.

If you're using C# 3.0 you can use linq, way better and way more elegant:

List<int> myList = GetListOfIntsFromSomewhere();

// This will filter out the list of ints that are > than 7, Where returns an
// IEnumerable<T> so a call to ToList is required to convert back to a List<T>.
List<int> filteredList = myList.Where( x => x > 7).ToList();

If you can't find the .Where, that means you need to import using System.Linq; at the top of your file.

jQuery is not letting you just simply access the events for a given element. You can access them using undocumented internal method

$._data(element, "events")

But it still won't give you all the events, to be precise won't show you events assigned with

$([selector|element]).on()

These events are stored inside document, so you can fetch them by browsing through

$._data(document, "events")

but that is hard work, as there are events for whole webpage.

Tom G above created function that filters document for only events of given element and merges output of both methods, but it had a flaw of duplicating events in the output (and effectively on the element's jQuery internal event list messing with your application). I fixed that flaw and you can find the code below. Just paste it into your dev console or into your app code and execute it when needed to get nice list of all events for given element.

What is important to notice, element is actually HTMLElement, not jQuery object.

function getEvents(element) {
    var elemEvents = $._data(element, "events");
    var allDocEvnts = $._data(document, "events");
    function equalEvents(evt1, evt2)
    {
        return evt1.guid === evt2.guid;
    }

    for(var evntType in allDocEvnts) {
        if(allDocEvnts.hasOwnProperty(evntType)) {
            var evts = allDocEvnts[evntType];
            for(var i = 0; i < evts.length; i++) {
                if($(element).is(evts[i].selector)) {
                    if(elemEvents == null) {
                        elemEvents = {};
                    }
                    if(!elemEvents.hasOwnProperty(evntType)) {
                        elemEvents[evntType] = [];
                    }
                    if(!elemEvents[evntType].some(function(evt) { return equalEvents(evt, evts[i]); })) {
                        elemEvents[evntType].push(evts[i]);
                    }
                }
            }
        }
    }
    return elemEvents;
}

mkdir -p dir;

NOTE:- This will also create any intermediate directories that don't exist; for instance,

Check out mkdir -p

or try this:-

if [[ ! -e $dir ]]; then
    mkdir $dir
elif [[ ! -d $dir ]]; then
    echo "$Message" 1>&2

In Laravel 5.1, you specify the connection:

$users = DB::connection('foo')->select(...);

Default, Laravel uses the default connection. It is simple, isn't it?

Read more here: http://laravel.com/docs/5.1/database#accessing-connections

You can check with null or Number.

First, add a reference to Microsoft.VisualBasic in your application.

Then, use the following code:

bool b = Microsoft.VisualBasic.Information.IsNumeric("null");
bool c = Microsoft.VisualBasic.Information.IsNumeric("abc");

In the above, b and c should both be false.

Looks like you are missing a leading slash. Perhaps try:

Scanner s = new Scanner(new File("/home/me/java/ex.txt"));

(as to where it looks for files by default, it is where the JVM is run from for relative paths like the one you have in your question)

I use

setTranscriptMode(ListView.TRANSCRIPT_MODE_NORMAL);

to add entries at the bottom, and older entries scroll off the top, like a chat transcript

you can as well try:

scanner := bufio.NewScanner(os.Stdin)
for scanner.Scan() {
    fmt.Println(scanner.Text())
}

if scanner.Err() != nil {
    // handle error.
}

It looks like you indented so_far = new too much. Try this:

if guess in word:
    print("\nYes!", guess, "is in the word!")

    # Create a new variable (so_far) to contain the guess
    new = ""
    i = 0
    for i in range(len(word)):
        if guess == word[i]:
            new += guess
        else:
            new += so_far[i]
    so_far = new # unindented this

For a GUI to do this I have just found that 'gitk' supports named views. The views have several options for selecting commits. One handy one is a box for selecting "All tags". That seems to work for me to see the tags.

I just had the same error (with PHP 5.2.6), and all I had to do is enable the MySQL-specific PDO driver:

TL;DR

In your php.ini file, you should have the following line (uncommented):

• extension=php_pdo_mysql.dll on Windows
• extension=php_pdo_mysql.so on Linux/Mac

Longer explanation:

1. open php.ini in a text editor

   • _{e.g. its default path on Windows: C:\Program Files (x86)\PHP\v5.X\php.ini (substitute v5.x with the version you installed) or C:\Windows\php.ini, etc.}
   • _{or on Linux: /etc/php5/apache2/php.ini (e.g. this is the path on Ubuntu) or /etc/php5/cli/php.ini, /etc/php5/cgi/php.ini, etc.}
   • _{or you can get to know where it is like this:}
     • _{php --ini | find /i "Loaded" in Windows command prompt OR}
     • _{php --ini | grep "Loaded" in Linux/Mac terminal}
     • _{using phpinfo(), and looking for the line "Loaded Configuration File"}

2. and remove the semicolon from the beginning of the following line (to uncomment it):

   • ;extension=php_pdo_mysql.dll on Windows
     • OR ;extension=php_pdo_mysql.so on Linux/Mac
   • of course, if this line doesn't exist, you should paste it
   • so as a result the expected line would look like this in php.ini:
     • extension=php_pdo_mysql.dll on Windows
     • OR extension=php_pdo_mysql.so on Linux/Mac

3. You may need to restart your web server.

That solved my problem.

Here is some explanation for method vs. function using JavaScript examples:

test(20, 50); is function define and use to run some steps or return something back that can be stored/used somewhere.

You can reuse code: Define the code once and use it many times.

You can use the same code many times with different arguments, to produce different results.

var x = myFunction(4, 3);   // Function is called, return value will end up in x

function myFunction(a, b) {
    return a * b;          // Function returns the product of a and b
}

var test = something.test(); here test() can be a method of some object or custom defined a prototype for inbuilt objects, here is more explanation:

JavaScript methods are the actions that can be performed on objects.

A JavaScript method is a property containing a function definition.

Built-in property/method for strings in javascript:

var message = "Hello world!";
var x = message.toUpperCase();
//Output: HELLO WORLD!

Custom example:

function person(firstName, lastName, age, eyeColor) {
    this.firstName = firstName;  
    this.lastName = lastName;
    this.age = age;
    this.eyeColor = eyeColor;
    this.changeName = function (name) {
        this.lastName = name;
    };
}

something.changeName("SomeName"); //This will change 'something' objject's name to 'SomeName'

You can define properties for String, Array, etc as well for example

String.prototype.distance = function (char) {
    var index = this.indexOf(char);

    if (index === -1) {
        console.log(char + " does not appear in " + this);
    } else {
        console.log(char + " is " + (this.length - index) + " characters from the end of the string!");
    }
};

var something = "ThisIsSomeString"

// now use distance like this, run and check console log

something.distance("m");

It supports fetching fields and array items, e.g.:

System.out.println(""+Refl.getValue(b,"x.q[0].z.y"));

there is no difference between dots and braces, they are just delimiters, and empty field names are ignored:

System.out.println(""+Refl.getValue(b,"x.q[0].z.y[value]"));
System.out.println(""+Refl.getValue(b,"x.q.1.y.z.value"));
System.out.println(""+Refl.getValue(b,"x[q.1]y]z[value"));

If you are using Joseph's answer which is a great answer, and you run these back to back like this:

dim i = GetRandom(1, 1715)
dim o = GetRandom(1, 1715)

Then the result could come back the same over and over because it processes the call so quickly. This may not have been an issue in '08, but since the processors are much faster today, the function doesn't allow the system clock enough time to change prior to making the second call.

Since the System.Random() function is based on the system clock, we need to allow enough time for it to change prior to the next call. One way of accomplishing this is to pause the current thread for 1 millisecond. See example below:

Public Function GetRandom(ByVal min as Integer, ByVal max as Integer) as Integer
    Static staticRandomGenerator As New System.Random
    max += 1
    Return staticRandomGenerator.Next(If(min > max, max, min), If(min > max, min, max))
End Function

For users of the Nrwl extensions who come across this thread: all commands are intercepted by Nx (e.g., ng generate component myCompent) and then passed down to the AngularCLI.

The command to get SCSS working in an Nx workspace:

Simulator doesn't have a Camera. If you want to access a camera you need a device. You can't test camera on simulator. You can only check the photo and video gallery.

The answers above will work for changing the values.

If you want to change the number of cells in your list (e.g. I have a list called 'revisions' which has 4 items, I now need 7 items) you will find that you can't simply select your list and amend it on the sheet, So:

go to your 'Formulas' tab

choose "Name Manager"

a pop up box will show what is available for editing. Your list should be in it. Select your list and edit the range.

OpenSSH cannot use PKCS#12 files out of the box. As others suggested, you must extract the private key in PEM format which gets you from the land of OpenSSL to OpenSSH. Other solutions mentioned here don’t work for me. I use OS X 10.9 Mavericks (10.9.3 at the moment) with “prepackaged” utilities (OpenSSL 0.9.8y, OpenSSH 6.2p2).

First, extract a private key in PEM format which will be used directly by OpenSSH:

openssl pkcs12 -in filename.p12 -clcerts -nodes -nocerts | openssl rsa > ~/.ssh/id_rsa

I strongly suggest to encrypt the private key with password:

openssl pkcs12 -in filename.p12 -clcerts -nodes -nocerts | openssl rsa -passout 'pass:Passw0rd!' > ~/.ssh/id_rsa

Obviously, writing a plain-text password on command-line is not safe either, so you should delete the last command from history or just make sure it doesn’t get there. Different shells have different ways. You can prefix your command with space to prevent it from being saved to history in Bash and many other shells. Here is also how to delete the command from history in Bash:

history -d $(history | tail -n 2 | awk 'NR == 1 { print $1 }')

Alternatively, you can use different way to pass a private key password to OpenSSL - consult OpenSSL documentation for pass phrase arguments.

Then, create an OpenSSH public key which can be added to authorized_keys file:

ssh-keygen -y -f ~/.ssh/id_rsa > ~/.ssh/id_rsa.pub

Try this one:

   $("div.subtab_left li.notebook a").click(function(e) {
    e.preventDefault();
    return false;   
    });

This worked for me:

dt.DefaultView.Sort = "Town ASC, Cutomer ASC";
dt = dt.DefaultView.ToTable();

You can just do that too, it seems to work well too. sc create "Servicename" binPath= "Path\To\your\App.exe" DisplayName= "My Custom Service"

You can open the registry and add a string named Description in your service's registry key to add a little more descriptive information about it. It will be shown in services.msc.

Simply you can aadd --force at the end of the command. Like:

sudo docker rmi <docker_image_id> --force

To make it more intelligent you can add as:

sudo docker stop $(docker ps | grep <your_container_name> | awk '{print $1}')

sudo docker rm $(docker ps | grep <your_container_name> | awk '{print $1}')

sudo docker rmi $(docker images | grep <your_image_name> | awk '{print $3}') --force

Here in docker ps $1 is the first column, i.e. the Docker container ID.

And docker images $3 is the third column, i.e. the Docker image ID.

Client-side validation was not being executed at all on my web form and I had no idea why. It turns out the problem was the name of the javascript function was the same as the server control ID.

So you can't do this...

<script>
  function vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="vld" />

But this works:

<script>
  function validate_vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="validate_vld" />

I'm guessing it conflicts with internal .NET Javascript?

yes, thats possible. just use the rgba-syntax for your background-color.

.menue{
  background-color: rgba(255, 0, 0, 0.5); //semi-transparent red
}

In PostgreSQL, while adding a field it would be added at the end of the table. If we need to insert into particular position then

alter table tablename rename to oldtable;
create table tablename (column defs go here);
insert into tablename (col1, col2, col3) select col1, col2, col3 from oldtable;

You can use date_diff to calculate the difference between two dates:

$date1 = date_create("2013-03-15");
$date2 = date_create("2013-12-12");
$diff =  date_diff($date1 , $date2);
echo  $diff->format("%R%a days");

R.id.button is not part of R.layout.activity_main. How should the activity find it in the content view?

The layout that contains the button is displayed by the Fragment, so you have to get the Button there, in the Fragment.

DateTime? MyDateTime{get;set;}

MyDateTime = (dr["f1"] == DBNull.Value) ? (DateTime?)null : ((DateTime)dr["f1"]);

Yes you can go to File -> Settings -> Editor -> Auto Import -> Java and make the following changes:

1.change Insert imports on paste value to All in drop down option.

2.markAdd unambigious imports on the fly option as checked.(For Window or linux user)

On a Mac, do the same thing in Android Studio -> Preferences

3.You can also use Eclipse shortcut key in Android Studio just go to in Android Studio

File -> Settings -> KeyMap -> Keymaps dropdown Option. Select from them

Thankyou

It's easy to copy a folder in a batch file.

 @echo off
 set src_folder = c:\whatever\*.*
 set dst_folder = c:\foo
 xcopy /S/E/U %src_folder% %dst_folder%

And you can add that batch file to your Windows login script pretty easily (assuming you have admin rights on the machine). Just go to the "User Manager" control panel, choose properties for your user, choose profile and set a logon script.

How you get to the user manager control panel depends on which version of Windows you run. But right clicking on My Computer and choosing manage and then choosing Local users and groups works for most versions.

The only sticky bit is "when the folder is updated". This sounds like a folder watcher, which you can't do in a batch file, but you can do pretty easily with .NET.

Deleting full .m2 local repository solved my problem, too.

If you don't know where it is, the locations are:

Unix/Mac OS X – ~/.m2/repository
Windows – C:\Documents and Settings\{your-username}\.m2\repository 
        ( %USERPROFILE%\.m2\repository too, as suggested by **MC Empero** )

Oracle's error message should be somewhat longer. It usually looks like this:

ORA-00001: unique constraint (TABLE_UK1) violated

The name in parentheses is the constrait name. It tells you which constraint was violated.

No this data is not exposed. The only data that is available is what is exposed through the HTTP request which might include their OS and other such information. But certainly not machine name.

If "ReferenceError: Model is not defined" error is raised, then you might try to use the following method:

$(document).ready(function () {

    @{  var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
         var json = serializer.Serialize(Model);
    }

    var model = @Html.Raw(json);
    if(model != null && @Html.Raw(json) != "undefined")
    {
        var id= model.Id;
        var mainFloorPlanId = model.MainFloorPlanId ;
        var imageDirectory = model.ImageDirectory ;
        var iconsDirectory = model.IconsDirectory ;
    }
});

Hope this helps...

Is it possible to declare a variable in Python (var=None):

def decl_var(var=None):
if var is None:
    var = []
var.append(1)
return var

An implicitly declared function is one that has neither a prototype nor a definition, but is called somewhere in the code. Because of that, the compiler cannot verify that this is the intended usage of the function (whether the count and the type of the arguments match). Resolving the references to it is done after compilation, at link-time (as with all other global symbols), so technically it is not a problem to skip the prototype.

It is assumed that the programmer knows what he is doing and this is the premise under which the formal contract of providing a prototype is omitted.

Nasty bugs can happen if calling the function with arguments of a wrong type or count. The most likely manifestation of this is a corruption of the stack.

Nowadays this feature might seem as an obscure oddity, but in the old days it was a way to reduce the number of header files included, hence faster compilation.

I think these kinds of problems are solved if we think about real life.

Bad Practice:

Example 1:

Darling everything is FINE/OK (HTTP CODE 200) - (Success):
{
  ...but I don't want us to be together anymore!!!... (Error)
  // Then everything isn't OK???
}

Example 2:

You are the best employee (HTTP CODE 200) - (Success):
{
  ...But we cannot continue your contract!!!... (Error)
  // Then everything isn't OK???
}

Good Practices:

 Darling I don't feel good (HTTP CODE 400) - (Error):
{
  ...I no longer feel anything for you, I think the best thing is to separate... (Error)
  // In this case, you are alerting me from the beginning that something is wrong ...
}

This is only my personal opinion, each one can implement it as it is most comfortable or needs.

Note: The idea for this explanation was drawn from a great friend @diosney

This ought to do it:

SELECT *
FROM YourTable
WHERE ARIDNR IN (
    SELECT ARIDNR
    FROM YourTable
    GROUP BY ARIDNR
    HAVING COUNT(*) > 1
)

The idea is to use the inner query to identify the records which have a ARIDNR value that occurs 1+ times in the data, then get all columns from the same table based on that set of values.

Is that what you need?

I don't see how that format is necessarily easy to work with in SQL queries, though.

You can do a recursive removal in one line using json.stringify's replacer argument

const removeEmptyValues = obj => (
  JSON.parse(JSON.stringify(obj, (k,v) => v ?? undefined))
)

Usage:

removeEmptyValues({a:{x:1,y:null,z:undefined}}) // Returns {a:{x:1}}

As mentioned in Emmanuel's comment, this technique only worked if your data structure contains only data types that can be put into JSON format (strings, numbers, lists, etc).

(This answer has been updated to use the new Nullish Coalescing operator. depending on browser support needs you may want to use this function instead: (k,v) => v!=null ? v : undefined)

I ran into the same problem and was able to resolve it in very powerful way that allows unlimited sorting possibilities.

I created a View using (saving) 2 sort orders (*explanation on how to do so below).

After that I simply applied the update queries to the View created and it worked great.

Here are the 2 queries I used on the view:

1st Query:

Update  MyView
Set SortID=0

2nd Query:

DECLARE @sortID int
SET     @sortID = 0
UPDATE  MyView
SET     @sortID = sortID = @sortID + 1

*To be able to save the sorting on the View I put TOP into the SELECT statement. This very useful workaround allows the View results to be returned sorted as set when the View was created when the View is opened. In my case it looked like:

(NOTE: Using this workaround will place an big load on the server if using a large table and it is therefore recommended to include as few fields as possible in the view if working with large tables)

SELECT     TOP (600000) 
dbo.Items.ID, dbo.Items.Code, dbo.Items.SortID, dbo.Supplier.Date, 
dbo.Supplier.Code AS Expr1
FROM         dbo.Items INNER JOIN
                      dbo.Supplier ON dbo.Items.SupplierCode = dbo.Supplier.Code
ORDER BY dbo.Supplier.Date, dbo.Items.ID DESC

Running: SQL Server 2005 on a Windows Server 2003

Remember that window is the global namespace. These two lines attempt to declare the same variable:

window.APP = { ... }
const APP = window.APP

The second definition is not allowed in strict mode (enabled with 'use strict' at the top of your file).

To fix the problem, simply remove the const APP = declaration. The variable will still be accessible, as it belongs to the global namespace.

Implicit Wait: During Implicit wait if the Web Driver cannot find it immediately because of its availability, the WebDriver will wait for mentioned time and it will not try to find the element again during the specified time period. Once the specified time is over, it will try to search the element once again the last time before throwing exception. The default setting is zero. Once we set a time, the Web Driver waits for the period of the WebDriver object instance.

Explicit Wait: There can be instance when a particular element takes more than a minute to load. In that case you definitely not like to set a huge time to Implicit wait, as if you do this your browser will going to wait for the same time for every element. To avoid that situation you can simply put a separate time on the required element only. By following this your browser implicit wait time would be short for every element and it would be large for specific element.

This will also work:

import java.io.*;

public class IOUtil {

    public static byte[] readFile(String file) throws IOException {
        return readFile(new File(file));
    }

    public static byte[] readFile(File file) throws IOException {
        // Open file
        RandomAccessFile f = new RandomAccessFile(file, "r");
        try {
            // Get and check length
            long longlength = f.length();
            int length = (int) longlength;
            if (length != longlength)
                throw new IOException("File size >= 2 GB");
            // Read file and return data
            byte[] data = new byte[length];
            f.readFully(data);
            return data;
        } finally {
            f.close();
        }
    }
}

See this blog post. If you call preventDefault on every touchstart then you should also have a CSS rule to disable touch scrolling like

.sortable-handler {
  touch-action: none;
}

If you have Python installed (works with either Python 2 or Python 3):

To select one file (or line from an arbitrary command), use

ls -1 | python -c "import sys; import random; print(random.choice(sys.stdin.readlines()).rstrip())"

To select N files/lines, use (note N is at the end of the command, replace this by a number)

ls -1 | python -c "import sys; import random; print(''.join(random.sample(sys.stdin.readlines(), int(sys.argv[1]))).rstrip())" N

If the compiler supports Named Return Value Optimization (http://msdn.microsoft.com/en-us/library/ms364057(v=vs.80).aspx), you can directly return the vector provide that there is no:

1. Different paths returning different named objects
2. Multiple return paths (even if the same named object is returned on all paths) with EH states introduced.
3. The named object returned is referenced in an inline asm block.

NRVO optimizes out the redundant copy constructor and destructor calls and thus improves overall performance.

There should be no real diff in your example.

hope you are doing well. you can use my code to crop image.you just have to make a class and use this class into your XMl and java classes. Crop image. you can crop your selected image into circle and square into many of option. hope fully it will works for you.because this is totally manageable for you and you can change it according to you.

enjoy your work :)

    outputStream().use { out ->
        bitmap.compress(format, quality, out)
        out.flush()
    }
}

usage example:

File(exportDir, "map.png").writeBitmap(bitmap, Bitmap.CompressFormat.PNG, 85)

For the real differences, we can find it in code, but I can't find the implement of the default behavior of the isinstance().

However we can get the similar one abc.__instancecheck__ according to __instancecheck__.

From above abc.__instancecheck__, after using test below:

# file tree
# /test/__init__.py
# /test/aaa/__init__.py
# /test/aaa/aa.py
class b():
pass

# /test/aaa/a.py
import sys
sys.path.append('/test')

from aaa.aa import b
from aa import b as c

d = b()

print(b, c, d.__class__)
for i in [b, c, object]:
    print(i, '__subclasses__',  i.__subclasses__())
    print(i, '__mro__', i.__mro__)
    print(i, '__subclasshook__', i.__subclasshook__(d.__class__))
    print(i, '__subclasshook__', i.__subclasshook__(type(d)))
print(isinstance(d, b))
print(isinstance(d, c))

<class 'aaa.aa.b'> <class 'aa.b'> <class 'aaa.aa.b'>
<class 'aaa.aa.b'> __subclasses__ []
<class 'aaa.aa.b'> __mro__ (<class 'aaa.aa.b'>, <class 'object'>)
<class 'aaa.aa.b'> __subclasshook__ NotImplemented
<class 'aaa.aa.b'> __subclasshook__ NotImplemented
<class 'aa.b'> __subclasses__ []
<class 'aa.b'> __mro__ (<class 'aa.b'>, <class 'object'>)
<class 'aa.b'> __subclasshook__ NotImplemented
<class 'aa.b'> __subclasshook__ NotImplemented
<class 'object'> __subclasses__ [..., <class 'aaa.aa.b'>, <class 'aa.b'>]
<class 'object'> __mro__ (<class 'object'>,)
<class 'object'> __subclasshook__ NotImplemented
<class 'object'> __subclasshook__ NotImplemented
True
False

I get this conclusion, For type:

# according to `abc.__instancecheck__`, they are maybe different! I have not found negative one 
type(INSTANCE) ~= INSTANCE.__class__
type(CLASS) ~= CLASS.__class__

For isinstance:

# guess from `abc.__instancecheck__`
return any(c in cls.__mro__ or c in cls.__subclasses__ or cls.__subclasshook__(c) for c in {INSTANCE.__class__, type(INSTANCE)})

BTW: better not to mix use relative and absolutely import, use absolutely import from project_dir( added by sys.path)

Interface is a contract you should comply to or given to, depending if you are implementer or a user.

Check your Elastic version.

I had these problem because I was looking at the incorrect version's documentation.

git log --oneline --decorate --all --graph

A visual tree with branch names included.

Use this to add it as an alias

git config --global alias.tree "log --oneline --decorate --all --graph"

You call it with

git tree

I had trouble with a .pfx file with openconnect. Renaming didn't solve the problem. I used keytool to convert it to .p12 and it worked.

keytool -importkeystore -destkeystore new.p12 -deststoretype pkcs12 -srckeystore original.pfx

In my case the password for the new file (new.p12) had to be the same as the password for the .pfx file.

Just go through your array and find the position:

var i = 0;
for(var item in Data) {
    if(Data[item].name == 'John')
        break;
    i++;
}
alert(i);

To understand the various transactional settings and behaviours adopted for Transaction management, such as REQUIRED, ISOLATION etc. you'll have to understand the basics of transaction management itself.

I am using flutter and installed virtual device using the terminal

flutter emulator --launch {avd_name} -v

will print a more detailed output, making it easier for debugging the specific errors

Enabling the virtualization options in BIOS worked in my particular case (VDT)

If you want more datesource configs e.g.

spring.datasource.test-while-idle=true 
spring.datasource.time-between-eviction-runs-millis=30000
spring.datasource.validation-query=select 1

you could use below code

@Bean
public DataSource dataSource() {
    DataSource dataSource = new DataSource(); // org.apache.tomcat.jdbc.pool.DataSource;
    dataSource.setDriverClassName(driverClassName);
    dataSource.setUrl(url);
    dataSource.setUsername(username);
    dataSource.setPassword(password);
    dataSource.setTestWhileIdle(testWhileIdle);     
    dataSource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMills);
    dataSource.setValidationQuery(validationQuery);
    return dataSource;
}

Or is ||

And is &&

Update for changed question:

You need to specify what you are comparing against in each logical section of the if statement.

if (title == "User greeting" || title == "User name") 
{
    // do stuff
}

This always works for me:

import android.app.Activity;
import android.content.Context;

public class yourClass {

 Context ctx;

 public yourClass (Handler handler, Context context) {
 super(handler);
    ctx = context;
 }

 //Use context (ctx) in your code like this:
 block1 = new Droid(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic), 100, 10);
 //OR
 builder.setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic));
 //OR
 final Intent intent = new Intent(ctx, MainActivity.class);
 //OR
 NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
 //ETC...

}

Not related to this question but example using a Fragment to access system resources/activity like this:

public boolean onQueryTextChange(String newText) {
 Activity activity = getActivity();
 Context context = activity.getApplicationContext();
 returnSomething(newText);
 return false;
}

View customerInfo = getActivity().getLayoutInflater().inflate(R.layout.main_layout_items, itemsLayout, false);
 itemsLayout.addView(customerInfo);

There is no exact functionality to do this.

Without wrapping another element inside, you could replace the border by a box-shadow and the padding by the border. But remember the box-shadow does not add to the dimensions of the element.

jsfiddle is being really slow, otherwise I'd add an example.

Yes, you can always use null instead of an object. Just be careful because some methods might throw error.

It would be 1.

also nulls would be factored in in the for loop, but you could use

 for(Item i : itemList) {
        if (i!= null) {
               //code here
        }
 }
