Pure Lua uses only what is in ANSI standard C. Luiz Figuereido's lposix module contains much of what you need to do more systemsy things.

You can also use the "timestamp" data type where it just needs "dd-mm-yyyy"

Like:

insert into emp values('12-12-2012');

considering there is just one column in the table... You can adjust the insertion values according to your table.

Another option to undo changes that weren't staged for commit is to run:

git restore <file>

To discard changes in the working directory.

One approach you can take is just to use CSS filters to change the appearance of the SVG graphics in the browser.

For example, if you have an SVG graphic that uses a fill color of red within the SVG code, you can turn it purple with a hue-rotate setting of 180 degrees:

#theIdOfTheImgTagWithTheSVGInIt {
    filter: hue-rotate(180deg);
    -webkit-filter: hue-rotate(180deg);
    -moz-filter: hue-rotate(180deg);
    -o-filter: hue-rotate(180deg);
    -ms-filter: hue-rotate(180deg);
}

Experiment with other hue-rotate settings to find the colors you want.

To be clear, the above CSS goes in the CSS that is applied to your HTML document. You are styling the img tag in the HTML code, not styling the code of the SVG.

And note that this won’t work with graphics that have a fill of black or white or gray. You have to have an actual color in there to rotate the hue of that color.

1.A very direct and easy to use example, make object to be passed implement Serializable.

class Object implements Serializable{
    String firstName;
   String lastName;
}

2.pass object in bundle

Bundle bundle = new Bundle();
Object Object = new Object();
bundle.putSerializable("object", object);

3.get passed object from bundle as Serializable then cast to Object.

Object object = (Object) getArguments().getSerializable("object");

I am trying to understand what Python's descriptors are and what they can be useful for.

Descriptors are class attributes (like properties or methods) with any of the following special methods:

• __get__ (non-data descriptor method, for example on a method/function)
• __set__ (data descriptor method, for example on a property instance)
• __delete__ (data descriptor method)

These descriptor objects can be used as attributes on other object class definitions. (That is, they live in the __dict__ of the class object.)

Descriptor objects can be used to programmatically manage the results of a dotted lookup (e.g. foo.descriptor) in a normal expression, an assignment, and even a deletion.

Functions/methods, bound methods, property, classmethod, and staticmethod all use these special methods to control how they are accessed via the dotted lookup.

A data descriptor, like property, can allow for lazy evaluation of attributes based on a simpler state of the object, allowing instances to use less memory than if you precomputed each possible attribute.

Another data descriptor, a member_descriptor, created by __slots__, allow memory savings by allowing the class to store data in a mutable tuple-like datastructure instead of the more flexible but space-consuming __dict__.

Non-data descriptors, usually instance, class, and static methods, get their implicit first arguments (usually named cls and self, respectively) from their non-data descriptor method, __get__.

Most users of Python need to learn only the simple usage, and have no need to learn or understand the implementation of descriptors further.

In Depth: What Are Descriptors?

A descriptor is an object with any of the following methods (__get__, __set__, or __delete__), intended to be used via dotted-lookup as if it were a typical attribute of an instance. For an owner-object, obj_instance, with a descriptor object:

• obj_instance.descriptor invokes
  descriptor.__get__(self, obj_instance, owner_class) returning a value
  This is how all methods and the get on a property work.

• obj_instance.descriptor = value invokes
  descriptor.__set__(self, obj_instance, value) returning None
  This is how the setter on a property works.

• del obj_instance.descriptor invokes
  descriptor.__delete__(self, obj_instance) returning None
  This is how the deleter on a property works.

obj_instance is the instance whose class contains the descriptor object's instance. self is the instance of the descriptor (probably just one for the class of the obj_instance)

To define this with code, an object is a descriptor if the set of its attributes intersects with any of the required attributes:

def has_descriptor_attrs(obj):
    return set(['__get__', '__set__', '__delete__']).intersection(dir(obj))

def is_descriptor(obj):
    """obj can be instance of descriptor or the descriptor class"""
    return bool(has_descriptor_attrs(obj))

A Data Descriptor has a __set__ and/or __delete__.
A Non-Data-Descriptor has neither __set__ nor __delete__.

def has_data_descriptor_attrs(obj):
    return set(['__set__', '__delete__']) & set(dir(obj))

def is_data_descriptor(obj):
    return bool(has_data_descriptor_attrs(obj))

Builtin Descriptor Object Examples:

• classmethod
• staticmethod
• property
• functions in general

Non-Data Descriptors

We can see that classmethod and staticmethod are Non-Data-Descriptors:

>>> is_descriptor(classmethod), is_data_descriptor(classmethod)
(True, False)
>>> is_descriptor(staticmethod), is_data_descriptor(staticmethod)
(True, False)

Both only have the __get__ method:

>>> has_descriptor_attrs(classmethod), has_descriptor_attrs(staticmethod)
(set(['__get__']), set(['__get__']))

Note that all functions are also Non-Data-Descriptors:

>>> def foo(): pass
... 
>>> is_descriptor(foo), is_data_descriptor(foo)
(True, False)

Data Descriptor, property

However, property is a Data-Descriptor:

>>> is_data_descriptor(property)
True
>>> has_descriptor_attrs(property)
set(['__set__', '__get__', '__delete__'])

Dotted Lookup Order

These are important distinctions, as they affect the lookup order for a dotted lookup.

obj_instance.attribute

1. First the above looks to see if the attribute is a Data-Descriptor on the class of the instance,
2. If not, it looks to see if the attribute is in the obj_instance's __dict__, then
3. it finally falls back to a Non-Data-Descriptor.

The consequence of this lookup order is that Non-Data-Descriptors like functions/methods can be overridden by instances.

Recap and Next Steps

We have learned that descriptors are objects with any of __get__, __set__, or __delete__. These descriptor objects can be used as attributes on other object class definitions. Now we will look at how they are used, using your code as an example.

Analysis of Code from the Question

Here's your code, followed by your questions and answers to each:

class Celsius(object):
    def __init__(self, value=0.0):
        self.value = float(value)
    def __get__(self, instance, owner):
        return self.value
    def __set__(self, instance, value):
        self.value = float(value)

class Temperature(object):
    celsius = Celsius()

1. Why do I need the descriptor class?

Your descriptor ensures you always have a float for this class attribute of Temperature, and that you can't use del to delete the attribute:

>>> t1 = Temperature()
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

Otherwise, your descriptors ignore the owner-class and instances of the owner, instead, storing state in the descriptor. You could just as easily share state across all instances with a simple class attribute (so long as you always set it as a float to the class and never delete it, or are comfortable with users of your code doing so):

class Temperature(object):
    celsius = 0.0

This gets you exactly the same behavior as your example (see response to question 3 below), but uses a Pythons builtin (property), and would be considered more idiomatic:

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

2. What is instance and owner here? (in get). What is the purpose of these parameters?

instance is the instance of the owner that is calling the descriptor. The owner is the class in which the descriptor object is used to manage access to the data point. See the descriptions of the special methods that define descriptors next to the first paragraph of this answer for more descriptive variable names.

3. How would I call/use this example?

Here's a demonstration:

>>> t1 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1
>>> 
>>> t1.celsius
1.0
>>> t2 = Temperature()
>>> t2.celsius
1.0

You can't delete the attribute:

>>> del t2.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

And you can't assign a variable that can't be converted to a float:

>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 7, in __set__
ValueError: invalid literal for float(): 0x02

Otherwise, what you have here is a global state for all instances, that is managed by assigning to any instance.

The expected way that most experienced Python programmers would accomplish this outcome would be to use the property decorator, which makes use of the same descriptors under the hood, but brings the behavior into the implementation of the owner class (again, as defined above):

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

Which has the exact same expected behavior of the original piece of code:

>>> t1 = Temperature()
>>> t2 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1.0
>>> t2.celsius
1.0
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: can't delete attribute
>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 8, in celsius
ValueError: invalid literal for float(): 0x02

Conclusion

We've covered the attributes that define descriptors, the difference between data- and non-data-descriptors, builtin objects that use them, and specific questions about use.

So again, how would you use the question's example? I hope you wouldn't. I hope you would start with my first suggestion (a simple class attribute) and move on to the second suggestion (the property decorator) if you feel it is necessary.

Please Try to pass parameters in httpoptions, you can follow function below

deleteAction(url, data) {
    const authToken = sessionStorage.getItem('authtoken');
    const options = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json',
        Authorization: 'Bearer ' + authToken,
      }),
      body: data,
    };
    return this.client.delete(url, options);
  }

You need to separate (in your thinking) the value of your selections and the representation of that value.

Pick a point in the JavaScript logic where they need to transition from string sentinels to native type and do a comparison there, preferably where it only gets done once for each value that needs to be converted. Remember to address what needs to happen if the string sentinel is not one the script knows (i.e. do you default to true or to false?)

In other words, yes, you need to depend on the string's value. :-)

stdlib float modf (float x, float *ipart) splits into two parts, check if return value (fractional part) == 0.

If you installed TensorFlow using pip, then the location of TensorBoard can be retrieved by issuing the command which tensorboard on the terminal. You can then edit the TensorBoard file, if necessary.

When you call a Linq statement like this:

// x = new List<string>();
var count = x.Count(s => s.StartsWith("x"));

You are actually using an extension method in the System.Linq namespace, so what the compiler translates this into is:

var count = Enumerable.Count(x, s => s.StartsWith("x"));

So the error you are getting above is because the first parameter, source (which would be x in the sample above) is null.

The entire transmission, including the query string, the whole URL, and even the type of request (GET, POST, etc.) is encrypted when using HTTPS.

I got the desired result by using

android:maxLines="2"
android:minLines="2"
android:ellipsize="end"

The trick is set maxLines and minLines to the same value... and Not just android:lines = "2", dosen't do the trick. Also you are avoiding any deprecated attributes.

You may also be interested in modifying it using jQuery: http://api.jquery.com/category/css/

The expression *src refers to the first character in the string, not the whole string. To reassign src to point to a different string tgt, use src = tgt;.

You could use string.chars().mapToObj(e -> new String(new char[] {e}));, though this is quite lengthy and only works with java 8. Here are a few more methods:

string.split(""); (Has an extra whitespace character at the beginning of the array if used before Java 8) string.split("|"); string.split("(?!^)"); Arrays.toString(string.toCharArray()).substring(1, string.length() * 3 + 1).split(", ");

The last one is just unnecessarily long, it's just for fun!

With the help of the given links I was able to solve the problem myself. The correct way is to get the resource ID with

getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
                             "raw", getPackageName());

To get it as a InputStream

InputStream ins = getResources().openRawResource(
            getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
            "raw", getPackageName()));

I encounter the same problem as you did. It turns out that your device is not connected with your computer.

Note:

• If you are using XCode, if both your computer and the device are using the same WIFI, you don't have to connect the device with the computer.
• For Android, or iOS running under terminal command, if you are using command line to run this, you have to make sure they are connected via cables. Sharing the same WIFI does not work. Make sure your device is really connected.
• Make sure you allowed USB Debugging on your android device.

If this still does not work, try to fire below command, where you can get richer info and details:

flutter run --verbose

And in my case it was simple: I used 'Add WCF Service' wizard in Visual Studio, which automatically created corresponding sections in app.config. Then I went on reading How to: Host a WCF Service in a Managed Application. The problem was: I didn't need to specify the url to run the web service.

Replace:

using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))

With:

using (ServiceHost host = new ServiceHost(typeof(HelloWorldService))

And the error is gone.

Generic idea: if you provide base address as a param and specify it in config, you get this error. Most probably, that's not the only way to get the error, thou.

Or is || in C#.

You may have a look at this.

I got the error as, "svn: Commit blocked by pre-commit hook (exit code 1) with output: Failed with exception: Lost connection to MySQL server at 'reading initial communication packet', system error: 104."

I tried 'svn commit' after 'svn cleanup'. And It works fine!.

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

Just a clarification on the answer given by Bkkbrad.

I tried this suggestion and it did not work for me.

For example,

split('aa|bb','\\|')

produced:

["","a","a","|","b","b",""]

But,

split('aa|bb','[|]')

produced the desired result:

["aa","bb"]

Including the metacharacter '|' inside the square brackets causes it to be interpreted literally, as intended, rather than as a metacharacter.

Read about request objects that your views receive: https://docs.djangoproject.com/en/dev/ref/request-response/#httprequest-objects

Also your hidden field needs a reliable name and then a value:

<input type="hidden" name="title" value="{{ source.title }}">

Then in a view:

request.POST.get("title", "")

For a VARBINARY(MAX) column, I had to use NVARCHAR(MAX):

cast(Content as nvarchar(max))

Or

CONVERT(NVARCHAR(MAX), Content, 0)
VARCHAR(MAX) didn't show the entire value

The Ookii Dialogs for WPF library has a class that provides an implementation of a folder browser dialog for WPF.

UIWebView will still continue to work with existing apps. WKWebView is available starting from iOS8, only WKWebView has a Nitro JavaScript engine.

To take advantage of this faster JavaScript engine in older apps you have to make code changes to use WKWebView instead of UIWebView. For iOS7 and older, you have to continue to use UIWebView, so you may have to check for iOS8 and then apply WKWebView methods / delegate methods and fallback to UIWebView methods for iOS7 and older. Also there is no Interface Builder component for WKWebView (yet), so you have to programmatically implement WKWebView.

You can implement WKWebView in Objective-C, here is simple example to initiate a WKWebView:

WKWebViewConfiguration *theConfiguration = [[WKWebViewConfiguration alloc] init];
WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:theConfiguration];
webView.navigationDelegate = self;
NSURL *nsurl=[NSURL URLWithString:@"http://www.apple.com"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[webView loadRequest:nsrequest];
[self.view addSubview:webView];

WKWebView rendering performance is noticeable in WebGL games and something that runs complex JavaScript algorithms, if you are using webview to load a simple html or website, you can continue to use UIWebView.

Here is a test app that can used to open any website using either UIWebView or WKWebView and you can compare performance, and then decide on upgrading your app to use WKWebView: https://itunes.apple.com/app/id928647773?mt=8&at=10ltWQ

I feel compelled to provide a counterpoint to Ashwini Chaudhary's answer. Despite appearances, the two-argument form of the round function does not round a Python float to a given number of decimal places, and it's often not the solution you want, even when you think it is. Let me explain...

The ability to round a (Python) float to some number of decimal places is something that's frequently requested, but turns out to be rarely what's actually needed. The beguilingly simple answer round(x, number_of_places) is something of an attractive nuisance: it looks as though it does what you want, but thanks to the fact that Python floats are stored internally in binary, it's doing something rather subtler. Consider the following example:

>>> round(52.15, 1)
52.1

With a naive understanding of what round does, this looks wrong: surely it should be rounding up to 52.2 rather than down to 52.1? To understand why such behaviours can't be relied upon, you need to appreciate that while this looks like a simple decimal-to-decimal operation, it's far from simple.

So here's what's really happening in the example above. (deep breath) We're displaying a decimal representation of the nearest binary floating-point number to the nearest n-digits-after-the-point decimal number to a binary floating-point approximation of a numeric literal written in decimal. So to get from the original numeric literal to the displayed output, the underlying machinery has made four separate conversions between binary and decimal formats, two in each direction. Breaking it down (and with the usual disclaimers about assuming IEEE 754 binary64 format, round-ties-to-even rounding, and IEEE 754 rules):

1. First the numeric literal 52.15 gets parsed and converted to a Python float. The actual number stored is 7339460017730355 * 2**-47, or 52.14999999999999857891452847979962825775146484375.

2. Internally as the first step of the round operation, Python computes the closest 1-digit-after-the-point decimal string to the stored number. Since that stored number is a touch under the original value of 52.15, we end up rounding down and getting a string 52.1. This explains why we're getting 52.1 as the final output instead of 52.2.

3. Then in the second step of the round operation, Python turns that string back into a float, getting the closest binary floating-point number to 52.1, which is now 7332423143312589 * 2**-47, or 52.10000000000000142108547152020037174224853515625.

4. Finally, as part of Python's read-eval-print loop (REPL), the floating-point value is displayed (in decimal). That involves converting the binary value back to a decimal string, getting 52.1 as the final output.

In Python 2.7 and later, we have the pleasant situation that the two conversions in step 3 and 4 cancel each other out. That's due to Python's choice of repr implementation, which produces the shortest decimal value guaranteed to round correctly to the actual float. One consequence of that choice is that if you start with any (not too large, not too small) decimal literal with 15 or fewer significant digits then the corresponding float will be displayed showing those exact same digits:

>>> x = 15.34509809234
>>> x
15.34509809234

Unfortunately, this furthers the illusion that Python is storing values in decimal. Not so in Python 2.6, though! Here's the original example executed in Python 2.6:

>>> round(52.15, 1)
52.200000000000003

Not only do we round in the opposite direction, getting 52.2 instead of 52.1, but the displayed value doesn't even print as 52.2! This behaviour has caused numerous reports to the Python bug tracker along the lines of "round is broken!". But it's not round that's broken, it's user expectations. (Okay, okay, round is a little bit broken in Python 2.6, in that it doesn't use correct rounding.)

Short version: if you're using two-argument round, and you're expecting predictable behaviour from a binary approximation to a decimal round of a binary approximation to a decimal halfway case, you're asking for trouble.

So enough with the "two-argument round is bad" argument. What should you be using instead? There are a few possibilities, depending on what you're trying to do.

• If you're rounding for display purposes, then you don't want a float result at all; you want a string. In that case the answer is to use string formatting:

  >>> format(66.66666666666, '.4f')
  '66.6667'
  >>> format(1.29578293, '.6f')
  '1.295783'
  

  Even then, one has to be aware of the internal binary representation in order not to be surprised by the behaviour of apparent decimal halfway cases.

  >>> format(52.15, '.1f')
  '52.1'
  

• If you're operating in a context where it matters which direction decimal halfway cases are rounded (for example, in some financial contexts), you might want to represent your numbers using the Decimal type. Doing a decimal round on the Decimal type makes a lot more sense than on a binary type (equally, rounding to a fixed number of binary places makes perfect sense on a binary type). Moreover, the decimal module gives you better control of the rounding mode. In Python 3, round does the job directly. In Python 2, you need the quantize method.

  >>> Decimal('66.66666666666').quantize(Decimal('1e-4'))
  Decimal('66.6667')
  >>> Decimal('1.29578293').quantize(Decimal('1e-6'))
  Decimal('1.295783')
  

• In rare cases, the two-argument version of round really is what you want: perhaps you're binning floats into bins of size 0.01, and you don't particularly care which way border cases go. However, these cases are rare, and it's difficult to justify the existence of the two-argument version of the round builtin based on those cases alone.

Ok, You should "construct" the html and find the .content div.

like this:

$.ajax({
   url:href,
   type:'GET',
   success: function(data){
       $('#content').html($(data).find('#content').html());
   }
});

Simple!

the following code worked fine for me. kindly check other setting in your web config

    </system.webServer>

int min and max values

Int -2,147,483,648 / 2,147,483,647 Int 64 -9,223,372,036,854,775,808 / 9,223,372,036,854,775,807

i guess you could set a to equal 9,223,372,036,854,775,807 but it would need to be an int64

if you always want a to be grater that b why do you need to check it? just set it to be true always

The second parameter of findBy is for ORDER.

$ens = $em->getRepository('AcmeBinBundle:Marks')
          ->findBy(
             array('type'=> 'C12'), 
             array('id' => 'ASC')
           );

None of the above answers worked for me. I kept getting this error:

Copy-Item : Access is denied

+ FullyQualifiedErrorId : ItemExistsUnauthorizedAccessError,Microsoft.PowerShell.Commands.CopyItemCommand

So this did it for me:

netsh advfirewall firewall set rule group="File and Printer Sharing" new enable=yes

Then from my host my machine in the Run box I just did this:

Try:

int i = Convert.ToInt32(dt.Rows.Count);

I think it's the shortest, thus the simplest way.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <ListView
        android:id="@+id/listview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
    </ListView>

</LinearLayout>

This is your adapter

class yourAdapter extends BaseAdapter {

    Context context;
    String[] data;
    private static LayoutInflater inflater = null;

    public yourAdapter(Context context, String[] data) {
        // TODO Auto-generated constructor stub
        this.context = context;
        this.data = data;
        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return data.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return data[position];
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View vi = convertView;
        if (vi == null)
            vi = inflater.inflate(R.layout.row, null);
        TextView text = (TextView) vi.findViewById(R.id.text);
        text.setText(data[position]);
        return vi;
    }
}

Your java activity

public class StackActivity extends Activity {

    ListView listview;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        listview = (ListView) findViewById(R.id.listview);
        listview.setAdapter(new yourAdapter(this, new String[] { "data1",
                "data2" }));
    }
}

the results

I have created a generalised solution. The function below will change ids and names of cloned object. In most cases, you will need the row number so Just add "data-row-id" attribute to the object.

function renameCloneIdsAndNames( objClone ) {

    if( !objClone.attr( 'data-row-id' ) ) {
        console.error( 'Cloned object must have \'data-row-id\' attribute.' );
    }

    if( objClone.attr( 'id' ) ) {
        objClone.attr( 'id', objClone.attr( 'id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } ) );
    }

    objClone.attr( 'data-row-id', objClone.attr( 'data-row-id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } ) );

    objClone.find( '[id]' ).each( function() {

        var strNewId = $( this ).attr( 'id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } );

        $( this ).attr( 'id', strNewId );

        if( $( this ).attr( 'name' ) ) {
            var strNewName  = $( this ).attr( 'name' ).replace( /\[\d+\]/g, function( strName ) {
                strName = strName.replace( /[\[\]']+/g, '' );
                var intNumber = parseInt( strName ) + 1;
                return '[' + intNumber + ']'
            } );
            $( this ).attr( 'name', strNewName );
        }
    });

    return objClone;
}

Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

plt.subplots is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:

import numpy as np
import matplotlib.pyplot as plt

x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()

Ctrl + Enter

%matplotlib inline

Magic Line :D

See: Plotting with Matplotlib.

I append one space for every element of the hash to see it well:

print map {$_ . " "} %h, "\n";

You could use :

int a = 12;
if (a>0 || a<0){
cout << "Your text"<<endl;
}

I'm pretty sure it works.

I wrote a tiny function for this purpose. Feel free to repurpose,

def is_json_key_present(json, key):
    try:
        buf = json[key]
    except KeyError:
        return False

    return True

After going down a bit of a bit of a rabbit hole trying to follow the answers to this question (maybe because I had to do this in a visual studio project), I found the easier path was to

1. Cut and paste the file(s) I no longer want to track into a temporary location

2. Commit the "deletion" of those files

3. Commit a modification of the .gitignore to exclude the files I had temporarily moved

4. Move the files back into the folder.

I found this to be the most straight forward way to go about it (at least in a visual studio, or I would assume other IDE heave based environment like Android Studio), without accidentally shooting myself in the foot with a pretty pervasive git rm -rf --cached . , after which the visual studio project I was working on didn't load.

Have a look at: https://developers.google.com/accounts/docs/OAuth2UserAgent#handlingtheresponse

It says:

Other parameters included in the response include expires_in and token_type. These parameters describe the lifetime of the token in seconds...

let url = URL(string: "URLSTRING HERE")
let anyvar =  String(describing: url)

I just had this problem. Turns out the XML file (not the contents) was not encoded in utf-8, but in ISO-8859-1. You can check this on a Mac with file -I xml_filename.

I used Sublime to change the file encoding to utf-8, and lxml imported it no issues.

Use this:

[webView loadHTMLString:htmlString baseURL:[[NSBundle mainBundle] bundleURL]];

Why so complicated? When you can do:

var loadTime = window.performance.timing.domContentLoadedEventEnd- window.performance.timing.navigationStart;

If you need more times check out the window.performance object:

console.log(window.performance);

Will show you the timing object:

connectEnd                 Time when server connection is finished.
connectStart               Time just before server connection begins.
domComplete                Time just before document readiness completes.
domContentLoadedEventEnd   Time after DOMContentLoaded event completes.
domContentLoadedEventStart Time just before DOMContentLoaded starts.
domInteractive             Time just before readiness set to interactive.
domLoading                 Time just before readiness set to loading.
domainLookupEnd            Time after domain name lookup.
domainLookupStart          Time just before domain name lookup.
fetchStart                 Time when the resource starts being fetched.
loadEventEnd               Time when the load event is complete.
loadEventStart             Time just before the load event is fired.
navigationStart            Time after the previous document begins unload.
redirectCount              Number of redirects since the last non-redirect.
redirectEnd                Time after last redirect response ends.
redirectStart              Time of fetch that initiated a redirect.
requestStart               Time just before a server request.
responseEnd                Time after the end of a response or connection.
responseStart              Time just before the start of a response.
timing                     Reference to a performance timing object.
navigation                 Reference to performance navigation object.
performance                Reference to performance object for a window.
type                       Type of the last non-redirect navigation event.

More Info

I have been struggling with VS2010/DNFW 4.5 integration and have finally got this working. Starting in VS 2008, a cache of assemblies was introduced that is used by Visual Studio called the "Referenced Assemblies". This file cache for VS 2010 is located at \Reference Assemblies\Microsoft\Framework.NetFramework\v4.0. Visual Studio loads framework assemblies from this location instead of from the framework installation directory. When Microsoft says that VS 2010 does not support DNFW 4.5 what they mean is that this directory does not get updated when DNFW 4.5 is installed. Once you have replace the files in this location with the updated DNFW 4.5 files, you will find that VS 2010 will happily function with DNFW 4.5.

To complete the other answers, in lodash 4 to ignore only undefined and null (And not properties like false) you can use a predicate in _.pickBy:

_.pickBy(obj, v !== null && v !== undefined)

Example below :

const obj = { a: undefined, b: 123, c: true, d: false, e: null};_x000D_
_x000D_
const filteredObject = _.pickBy(obj, v => v !== null && v !== undefined);_x000D_
_x000D_
console.log = (obj) => document.write(JSON.stringify(filteredObject, null, 2));_x000D_
console.log(filteredObject);

Of course... Almost all classes implements several interfaces. On any page of java documentation on Oracle you have a subsection named "All implemented interfaces".

Here an example of the Date class.

I don't know if is the case,

If you create a migration before adding a DbSet your sql table will have a name of your model, generally in singular form or by convention we name DbSet using plural form.

So try to verifiy if your DbSet name have a same name as your Table. If not try to alter configuration.

In MySQL, @variable indicates a user-defined variable. You can define your own.

SET @a = 'test';
SELECT @a;

Outside of stored programs, a variable, without @, is a system variable, which you cannot define yourself.

The scope of this variable is the entire session. That means that while your connection with the database exists, the variable can still be used.

This is in contrast with MSSQL, where the variable will only be available in the current batch of queries (stored procedure, script, or otherwise). It will not be available in a different batch in the same session.

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

You can use a combination of Where and Any for finding not in:

var NotInRecord =list1.Where(p => !list2.Any(p2 => p2.Email  == p.Email));

Just use --repo option for git push command. Like this:

$ git push --repo https://name:[email protected]/name/repo.git

I just encountered this problem myself and found that Ubuntu 14.04 uses Upstart instead of Systemd, so systemctl commands will not work. This changed in 15.04, so one way around this would be to update your ubuntu install.

If this is not an option for you (it's not for me right now), you need to find the Upstart command that does what you need to do.

For enable, the generic looks to be the following:

update-rc.d <service> enable

Link to Ubuntu documentation: https://wiki.ubuntu.com/SystemdForUpstartUsers

Load a page within a page using an iframe. The following should serve as a good starting point.

<body>
  <div>
    <iframe src="page1.html" name="targetframe" allowTransparency="true" scrolling="no" frameborder="0" >
    </iframe>
  </div>

  <br/>

  <div>
    <a href="page2.html" target="targetframe">Link to Page 2</a><br />
    <a href="page3.html" target="targetframe">Link to Page 3</a>
  </div>
</body>

Instead of using np.argsort you could use np.argpartition - if you only need the indices of the lowest/highest n elements.

That doesn't require to sort the whole array but just the part that you need but note that the "order inside your partition" is undefined, so while it gives the correct indices they might not be correctly ordered:

>>> avgDists = [1, 8, 6, 9, 4]
>>> np.array(avgDists).argpartition(2)[:2]  # indices of lowest 2 items
array([0, 4], dtype=int64)

>>> np.array(avgDists).argpartition(-2)[-2:]  # indices of highest 2 items
array([1, 3], dtype=int64)

This code written above worked for me as well. Although, you can use the code I am writing here:

@echo off

@echo>"d:\testing\dblank.txt

If you want to write some text to dblank.txt then add the following line in the end of your code

@echo Writing text to dblank.txt> dblank.txt

Coming at this almost a year later, there's a different manner in which I solved my particular problem. Since I wanted the link to be handled by my own app, there is a solution that is a bit simpler.

Besides the default intent filter, I simply let my target activity listen to ACTION_VIEW intents, and specifically, those with the scheme com.package.name

<intent-filter>
    <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="com.package.name" />  
</intent-filter>

This means that links starting with com.package.name:// will be handled by my activity.

So all I have to do is construct a URL that contains the information I want to convey:

com.package.name://action-to-perform/id-that-might-be-needed/

In my target activity, I can retrieve this address:

Uri data = getIntent().getData();

In my example, I could simply check data for null values, because when ever it isn't null, I'll know it was invoked by means of such a link. From there, I extract the instructions I need from the url to be able to display the appropriate data.

If you are in Windows, please select "run as administrator" for the command prompt for executing the java app (ie: for executing java -jar ${your_jar_path}\lombok-1.14.6.jar).

I use Visual Studio git plugin, and I have some websites running on IIS I wanted to move. A simple way that worked for me:

1. Close Visual Studio.

2. Move the code (including git folder, etc)

3. Click on the solution file from the new location

This refreshes the mapping to the new location, using the existing local git files that were moved. Once i was back in Visual Studio, my Team Explorer window showed the repos in the new location.

A silly hack I did was to set the height of the element to zero but overflow:visible; combining this with pointer-events:none; seems to cover all the bases.

.overlay {
    height:0px;
    overflow:visible;
    pointer-events:none;
    background:none !important;
}

Each argument passed via command line can be accessed with: Wscript.Arguments.Item(0) Where the zero is the argument number: ie, 0, 1, 2, 3 etc.

So in your code you could have:

strFolder = Wscript.Arguments.Item(0) 

Set FSO = CreateObject("Scripting.FileSystemObject")
Set File = FSO.OpenTextFile(strFolder, 2, True)
File.Write "testing"
File.Close
Set File = Nothing
Set FSO = Nothing
Set workFolder = Nothing

Using wscript.arguments.count, you can error trap in case someone doesn't enter the proper value, etc.

MS Technet examples

Change your configuration to this (add a slash):

RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule (.*) http://www.example.com/$1 [R=301,L] 

Or the solution outlined below (proposed by @absiddiqueLive) will work for any domain:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

If you need to support http and https and preserve the protocol choice try the following:

RewriteRule ^login\$ https://www.%{HTTP_HOST}/login [R=301,L]

Where you replace login with checkout.php or whatever URL you need to support HTTPS on.

I'd argue this is a bad idea though. For the reasoning please read this answer.

Use the dec argument to set "," as the decimal point by adding:

 ce <- read.table("file.txt", header = TRUE, dec = ",")

Pandas allows you to plot tables using matplotlib (details here). Usually this plots the table directly onto a plot (with axes and everything) which is not what you want. However, these can be removed first:

import matplotlib.pyplot as plt
import pandas as pd
from pandas.table.plotting import table # EDIT: see deprecation warnings below

ax = plt.subplot(111, frame_on=False) # no visible frame
ax.xaxis.set_visible(False)  # hide the x axis
ax.yaxis.set_visible(False)  # hide the y axis

table(ax, df)  # where df is your data frame

plt.savefig('mytable.png')

The output might not be the prettiest but you can find additional arguments for the table() function here. Also thanks to this post for info on how to remove axes in matplotlib.

EDIT:

Here is a (admittedly quite hacky) way of simulating multi-indexes when plotting using the method above. If you have a multi-index data frame called df that looks like:

first  second
bar    one       1.991802
       two       0.403415
baz    one      -1.024986
       two      -0.522366
foo    one       0.350297
       two      -0.444106
qux    one      -0.472536
       two       0.999393
dtype: float64

First reset the indexes so they become normal columns

df = df.reset_index() 
df
    first second       0
0   bar    one  1.991802
1   bar    two  0.403415
2   baz    one -1.024986
3   baz    two -0.522366
4   foo    one  0.350297
5   foo    two -0.444106
6   qux    one -0.472536
7   qux    two  0.999393

Remove all duplicates from the higher order multi-index columns by setting them to an empty string (in my example I only have duplicate indexes in "first"):

df.ix[df.duplicated('first') , 'first'] = '' # see deprecation warnings below
df
  first second         0
0   bar    one  1.991802
1          two  0.403415
2   baz    one -1.024986
3          two -0.522366
4   foo    one  0.350297
5          two -0.444106
6   qux    one -0.472536
7          two  0.999393

Change the column names over your "indexes" to the empty string

new_cols = df.columns.values
new_cols[:2] = '',''  # since my index columns are the two left-most on the table
df.columns = new_cols 

Now call the table function but set all the row labels in the table to the empty string (this makes sure the actual indexes of your plot are not displayed):

table(ax, df, rowLabels=['']*df.shape[0], loc='center')

et voila:

Your not-so-pretty but totally functional multi-indexed table.

EDIT: DEPRECATION WARNINGS

As pointed out in the comments, the import statement for table:

from pandas.tools.plotting import table

is now deprecated in newer versions of pandas in favour of:

from pandas.plotting import table 

EDIT: DEPRECATION WARNINGS 2

The ix indexer has now been fully deprecated so we should use the loc indexer instead. Replace:

df.ix[df.duplicated('first') , 'first'] = ''

with

df.loc[df.duplicated('first') , 'first'] = ''

You can modify the id without having to use getElementById

Example:

<div id = 'One' onclick = "One.id = 'Two'; return false;">One</div>

From Visual Studio 2015 consider to use out of the box Memory Usage diagnostic tool to collect and analyze memory usage data.

The Memory Usage tool lets you take one or more snapshots of the managed and native memory heap to help understand the memory usage impact of object types.

The approach I've found workable is git's submodule system. Using that you can submodule in a given version of the code and upgrading/downgrading is explicit and recorded - never haphazard.

The folder structure I've taken with this is:

+ myproject
++ src
+++ myproject
+++ github.com
++++ submoduled_project of some kind.

In my case because of using anchor link for CSS popup I've used this way:

Just save the pageYOffset first thing on click and then set the ScrollTop to that:

$(document).on('click','yourtarget',function(){
        var st=window.pageYOffset;
        $('html, body').animate({
                'scrollTop' : st
            });
});

Try this:

$str = "Hello Friend";

$arr1 = str_split($str);
$arr2 = str_split($str, 3);

print_r($arr1);
print_r($arr2);

The above example will output:

Array
(
    [0] => H
    [1] => e
    [2] => l
    [3] => l
    [4] => o
    [5] =>
    [6] => F
    [7] => r
    [8] => i
    [9] => e
    [10] => n
    [11] => d
)

Array

    [0] => Hel
    [1] => lo

The correct syntax to install cron in cygwin as Windows service is to pass -n as argument and not -D:

cygrunsrv --install cron --path /usr/sbin/cron --args -n

-D returns usage error when starting cron in cygwin:

$

$cygrunsrv --install cron --path /usr/sbin/cron --args -D

$cygrunsrv --start cron

cygrunsrv: Error starting a service: QueryServiceStatus: Win32 error 1062:

The service has not been started.

$cat /var/log/cron.log

cron: unknown option -- D

usage: /usr/sbin/cron [-n] [-x [ext,sch,proc,parc,load,misc,test,bit]]

$

Below page has a good explanation.

P.S. I had to run Cygwin64 Terminal on my Windows 10 PC as administrator in order to install cron as Windows service.

If you do not want to depend on throwing exception (which you probably should not) you can try this:

public static <T> T cast(Object o, Class<T> clazz) {
    return clazz.isInstance(o) ? clazz.cast(o) : null;
}

Continuing with Mecki's suggestion, this article pthread mutex vs pthread spinlock on Alexander Sandler's blog, Alex on Linux shows how the spinlock & mutexes can be implemented to test the behavior using #ifdef.

However, be sure to take the final call based on your observation, understanding as the example given is an isolated case, your project requirement, environment may be entirely different.

• cd /usr/local
• git status
• Discard all the changes (unless you actually want to try to commit to Homebrew - you probably don't)
• git status til it's clean
• brew update

I had a similar issue but my schema had a backslash in it. In this case, include the brackets around the schema.

ALTER SCHEMA dbo TRANSFER [DOMAIN\jonathan].MovieData;

In my case the problem was the subfolder that I was tying to push was a git folder itself

So I did the following

1. Go inside the subfolder that you want to push and run this:

rm -rf .git

2. Then run this:

 git rm --cached <subfolderName>

3. Then come to main project folder and run this (make sure to add / after folder name)

    git add <folderName>/
    git commit -m "Commit message"
    git push -f origin <branchName>

Use this as it can also act as responsive. :

background-size: cover;

Stack Smashing here is actually caused due to a protection mechanism used by gcc to detect buffer overflow errors. For example in the following snippet:

#include <stdio.h>

void func()
{
    char array[10];
    gets(array);
}

int main(int argc, char **argv)
{
    func();
}

The compiler, (in this case gcc) adds protection variables (called canaries) which have known values. An input string of size greater than 10 causes corruption of this variable resulting in SIGABRT to terminate the program.

To get some insight, you can try disabling this protection of gcc using option -fno-stack-protector while compiling. In that case you will get a different error, most likely a segmentation fault as you are trying to access an illegal memory location. Note that -fstack-protector should always be turned on for release builds as it is a security feature.

You can get some information about the point of overflow by running the program with a debugger. Valgrind doesn't work well with stack-related errors, but like a debugger, it may help you pin-point the location and reason for the crash.

To specify a variable is an array of objects:

$needles = getAllNeedles();
/* @var $needles Needle[] */
$needles[1]->...                        //codehinting works

This works in Netbeans 7.2 (I'm using it)

Works also with:

$needles = getAllNeedles();
/* @var $needles Needle[] */
foreach ($needles as $needle) {
    $needle->...                        //codehinting works
}

Therefore use of declaration inside the foreach is not necessary.

You can use np.concatenate() specifying which axis to append, using np.newaxis:

import numpy as np
movie = np.concatenate((img1[:,np.newaxis], img2[:,np.newaxis]), axis=3)

If you are reading from many files:

import glob
movie = np.concatenate([cv2.imread(p)[:,np.newaxis] for p in glob.glob('*.jpg')], axis=3)

What worked for me was fs.promises.

Example One:

const fs = require("fs")

fs.promises
  .writeFile(__dirname + '/test.json', "data", { encoding: 'utf8' })
  .then(() => {
    // Do whatever you want to do.
    console.log('Done');
  });

Example Two. Using Async-Await:

const fs = require("fs")

async function writeToFile() {
  await fs.promises.writeFile(__dirname + '/test-22.json', "data", {
    encoding: 'utf8'
  });

  console.log("done")
}

writeToFile()

Just a slight modification for the code written by Roel Van de Paar, as all credit goes to him. I am using this in Windows and it is working perfectly, both for setting and adding cookies:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--user-data-dir=chrome-data")
driver = webdriver.Chrome('chromedriver.exe',options=chrome_options)
driver.get('https://web.whatsapp.com')  # Already authenticated
time.sleep(30)

OK, I found it.

apt-cache policy <package name> will show the version details.

It also shows which version is currently installed and which versions are available to install.

For example, apt-cache policy hylafax+

SET myParam = IFNULL(myParam, 0);

Explanation: IFNULL(expression_1, expression_2)

The IFNULL function returns expression_1 if expression_1 is not NULL; otherwise it returns expression_2. The IFNULL function returns a string or a numeric based on the context where it is used.

Quoting from wikipedia:

A pointer references a location in memory, and obtaining the value at the location a pointer refers to is known as dereferencing the pointer.

Dereferencing is done by applying the unary * operator on the pointer.

int x = 5;
int * p;      // pointer declaration
p = &x;       // pointer assignment
*p = 7;       // pointer dereferencing, example 1
int y = *p;   // pointer dereferencing, example 2

"Dereferencing a NULL pointer" means performing *p when the p is NULL

There isn't a single answer to this question as there are too many variables, but SHA2 is not yet really cracked (see: Lifetimes of cryptographic hash functions) so it is still a good algorithm to use to store passwords in. The use of salt is good because it prevents attack from dictionary attacks or rainbow tables. Importance of a salt is that it should be unique for each password. You can use a format like [128-bit salt][512-bit password hash] when storing the hashed passwords.

The only viable way to attack is to actually calculate hashes for different possibilities of password and eventually find the right one by matching the hashes.

To give an idea about how many hashes can be done in a second, I think Bitcoin is a decent example. Bitcoin uses SHA256 and to cut it short, the more hashes you generate, the more bitcoins you get (which you can trade for real money) and as such people are motivated to use GPUs for this purpose. You can see in the hardware overview that an average graphic card that costs only $150 can calculate more than 200 million hashes/s. The longer and more complex your password is, the longer time it will take. Calculating at 200M/s, to try all possibilities for an 8 character alphanumberic (capital, lower, numbers) will take around 300 hours. The real time will most likely less if the password is something eligible or a common english word.

As such with anything security you need to look at in context. What is the attacker's motivation? What is the kind of application? Having a hash with random salt for each gives pretty good protection against cases where something like thousands of passwords are compromised.

One thing you can do is also add additional brute force protection by slowing down the hashing procedure. As you only hash passwords once, and the attacker has to do it many times, this works in your favor. The typical way to do is to take a value, hash it, take the output, hash it again and so forth for a fixed amount of iterations. You can try something like 1,000 or 10,000 iterations for example. This will make it that many times times slower for the attacker to find each password.

I have created an illustration that explains better than words, in my opinion:

A great way for cloning an array is with an array literal and the spread syntax. This is made possible by ES2015.

const objArray = [{name:'first'}, {name:'second'}, {name:'third'}, {name:'fourth'}];

const clonedArr = [...objArray];

console.log(clonedArr) // [Object, Object, Object, Object]

You can find this copy option in MDN's documentation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator#Copy_an_array

It is also an Airbnb's best practice. https://github.com/airbnb/javascript#es6-array-spreads

Note: The spread syntax in ES2015 goes one level deep while copying an array. Therefore, they are unsuitable for copying multidimensional arrays.

Actually, your code will pretty much work as is, just declare your callback as an argument and you can call it directly using the argument name.

The basics

function doSomething(callback) {
    // ...

    // Call the callback
    callback('stuff', 'goes', 'here');
}

function foo(a, b, c) {
    // I'm the callback
    alert(a + " " + b + " " + c);
}

doSomething(foo);

That will call doSomething, which will call foo, which will alert "stuff goes here".

Note that it's very important to pass the function reference (foo), rather than calling the function and passing its result (foo()). In your question, you do it properly, but it's just worth pointing out because it's a common error.

More advanced stuff

Sometimes you want to call the callback so it sees a specific value for this. You can easily do that with the JavaScript call function:

function Thing(name) {
    this.name = name;
}
Thing.prototype.doSomething = function(callback) {
    // Call our callback, but using our own instance as the context
    callback.call(this);
}

function foo() {
    alert(this.name);
}

var t = new Thing('Joe');
t.doSomething(foo);  // Alerts "Joe" via `foo`

You can also pass arguments:

function Thing(name) {
    this.name = name;
}
Thing.prototype.doSomething = function(callback, salutation) {
    // Call our callback, but using our own instance as the context
    callback.call(this, salutation);
}

function foo(salutation) {
    alert(salutation + " " + this.name);
}

var t = new Thing('Joe');
t.doSomething(foo, 'Hi');  // Alerts "Hi Joe" via `foo`

Sometimes it's useful to pass the arguments you want to give the callback as an array, rather than individually. You can use apply to do that:

function Thing(name) {
    this.name = name;
}
Thing.prototype.doSomething = function(callback) {
    // Call our callback, but using our own instance as the context
    callback.apply(this, ['Hi', 3, 2, 1]);
}

function foo(salutation, three, two, one) {
    alert(salutation + " " + this.name + " - " + three + " " + two + " " + one);
}

var t = new Thing('Joe');
t.doSomething(foo);  // Alerts "Hi Joe - 3 2 1" via `foo`

You should be able to do something along the lines of the following

UPDATE s
SET
    OrgAddress1 = bd.OrgAddress1,
    OrgAddress2 = bd.OrgAddress2,
    ...
    DestZip = bd.DestZip
FROM
    Shipment s, ProfilerTest.dbo.BookingDetails bd
WHERE
    bd.MyID = @MyId AND s.MyID2 = @MyID2

FROM statement can be made more optimial (using more specific joins), but the above should do the trick. Also, a nice side benefit to writing it this way, to see a preview of the UPDATE change UPDATE s SET to read SELECT! You will then see that data as it would appear if the update had taken place.

The ssh2 functions aren't very good. Hard to use and harder yet to install, using them will guarantee that your code has zero portability. My recommendation would be to use phpseclib, a pure PHP SFTP implementation.

This one is easy to remember, but might be slow. Use jQuery to copy non-null properties to an empty object. No deep copy unless you add true as first argument.

myObj = $.extend({}, myObj);

This answer is good for typescript / Angular 2, 4, 5+

I got this answer with the help of @rujmah answer above. His answer brings in the array count... and then find's the value and replaces it with another value...

What this answer does is simply grabs the array name that might be set in another variable via another module / component... in this case the array I build had a css name of stay-dates. So what this does is extract that name and then allows me to set it to another variable and use it like so. In my case it was an html css class.

let obj = this.highlightDays.find(x => x.css); let index = this.highlightDays.indexOf(obj); console.log('here we see what hightlightdays is ', obj.css); let dayCss = obj.css;

An Error Was Encountered Unable to load the requested file:

Sometimes we face this error because the requested file doesn't exist in that directory.

Suppose we have a folder home in views directory and trying to load home_view.php file as:

$this->load->view('home/home_view', $data);// $data is array

If home_view.php file doesn't exist in views/home directory then it will raise an error.

An Error Was Encountered Unable to load the requested file: home\home_view.php

So how to fix this error go to views/home and check the home_view.php file exist if not then create it.

$header3 = @("Field_1","Field_2","Field_3","Field_4","Field_5")

                $record = $record + "," + '"' + $property.Value + '"' 
            }
            else{

            }

}

I realize this is an old question. I found it several months ago when I was trying to do the same thing, and was underwhelmed by the answers given. They all seemed to deal with importing from Bitbucket to GitHub one repository at a time, either via commands issued à la carte, or via the GitHub importer.

I grabulated the code from a GitHub project called gitter and modified it to suite my needs.

Then, to use the script:

# create a list of repos
foo
bar
baz

# execute the script, iterating over your list
while read p; do ./bitbucket-to-github.rb -a -n $p; done<repos

# good nuff

You can use the following code.

main()
{
    int i = 0,j=0,count[26]={0};
    char ch = 97;
    char string[100]="Hello how are you buddy ?";
    for (i = 0; i < 100; i++)
    {
        for(j=0;j<26;j++)
            {
            if (tolower(string[i]) == (ch+j))
                {
                    count[j]++;
                }
        }
    }
    for(j=0;j<26;j++)
        {

            printf("\n%c -> %d",97+j,count[j]);

    }

}

Hope this helps.

The notion that regex doesn't support inverse matching is not entirely true. You can mimic this behavior by using negative look-arounds:

^((?!hede).)*$

The regex above will match any string, or line without a line break, not containing the (sub)string 'hede'. As mentioned, this is not something regex is "good" at (or should do), but still, it is possible.

And if you need to match line break chars as well, use the DOT-ALL modifier (the trailing s in the following pattern):

/^((?!hede).)*$/s

or use it inline:

/(?s)^((?!hede).)*$/

(where the /.../ are the regex delimiters, i.e., not part of the pattern)

If the DOT-ALL modifier is not available, you can mimic the same behavior with the character class [\s\S]:

/^((?!hede)[\s\S])*$/

Explanation

A string is just a list of n characters. Before, and after each character, there's an empty string. So a list of n characters will have n+1 empty strings. Consider the string "ABhedeCD":

    +----------------------------------------------------------+
S = ¦e1¦ A ¦e2¦ B ¦e3¦ h ¦e4¦ e ¦e5¦ d ¦e6¦ e ¦e7¦ C ¦e8¦ D ¦e9¦
    +----------------------------------------------------------+

index    0      1      2      3      4      5      6      7

where the e's are the empty strings. The regex (?!hede). looks ahead to see if there's no substring "hede" to be seen, and if that is the case (so something else is seen), then the . (dot) will match any character except a line break. Look-arounds are also called zero-width-assertions because they don't consume any characters. They only assert/validate something.

So, in my example, every empty string is first validated to see if there's no "hede" up ahead, before a character is consumed by the . (dot). The regex (?!hede). will do that only once, so it is wrapped in a group, and repeated zero or more times: ((?!hede).)*. Finally, the start- and end-of-input are anchored to make sure the entire input is consumed: ^((?!hede).)*$

As you can see, the input "ABhedeCD" will fail because on e3, the regex (?!hede) fails (there is "hede" up ahead!).

According to @jaiswal Rajan in his answer. You can do a pushViewController like this:

let storyBoard: UIStoryboard = UIStoryboard(name: "NewBotStoryboard", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "NewViewController") as! NewViewController
self.navigationController?.pushViewController(newViewController, animated: true)

if you want to change only the colour of the flag on hover use this:

This looks confusing because you are taking long as a datatype itself.

long is nothing but just the shorthand for long int when you are using it alone.

long is a modifier, you can use it with double also as long double.

long == long int.

Both of them take 4 bytes.

This works for me:

#! /bin/bash

CACERTS=$(readlink -e $(dirname $(readlink -e $(which keytool)))/../lib/security/cacerts)

if keytool -list -keystore $CACERTS -storepass changeit > /dev/null ; then
    echo $CACERTS
else
    echo 'Can not find cacerts file.' >&2
    exit 1
fi

Only for Linux. My Solaris has no readlink. In the end I used this Perl-Script:

#! /usr/bin/env perl
use strict;
use warnings;
use Cwd qw(realpath);
$_ = realpath((grep {-x && -f} map {"$_/keytool"} split(':', $ENV{PATH}))[0]);
die "Can not find keytool" unless defined $_;
my $keytool = $_;
print "Using '$keytool'.\n";
s/keytool$//;
$_ = realpath($_ . '../lib/security/cacerts');
die "Can not find cacerts" unless -f $_;
my $cacerts = $_;
print "Importing into '$cacerts'.\n";
`$keytool -list -keystore "$cacerts" -storepass changeit`;
die "Can not read key container" unless $? == 0;
exit if $ARGV[0] eq '-d';
foreach (@ARGV) {
    my $cert = $_;
    s/\.[^.]+$//;
    my $alias = $_;
    print "Importing '$cert' as '$alias'.\n";
    `keytool -importcert -file "$cert" -alias "$alias" -keystore "$cacerts" -storepass changeit`;
    warn "Can not import certificate: $?" unless $? == 0;
}

If you only care about that particular machine's traffic, use a capture filter instead, which you can set under Capture -> Options.

host 192.168.1.101

Wireshark will only capture packet sent to or received by 192.168.1.101. This has the benefit of requiring less processing, which lowers the chances of important packets being dropped (missed).

The biggest disadvantage of Text (together with NText and Image) is that it will be removed in a future version of SQL Server, as by the documentation. That will effectively make your schema harder to upgrade when that version of SQL Server will be released.

I've been trying to do something very similar but not using the nodes. However, my xml structure is a little different.

You have it like this:

<Metrics>
    <Metric id="TransactionCleanupThread.RefundOldTrans" type="timer" ...>

If it were like this instead:

<Metrics>
    <Metric>
        <id>TransactionCleanupThread.RefundOldTrans</id>
        <type>timer</type>
        .
        .
        .

Then you could simply use this SQL statement.

SELECT
    Sqm.SqmId,
    Data.value('(/Sqm/Metrics/Metric/id)[1]', 'varchar(max)') as id,
    Data.value('(/Sqm/Metrics/Metric/type)[1]', 'varchar(max)') AS type,
    Data.value('(/Sqm/Metrics/Metric/unit)[1]', 'varchar(max)') AS unit,
    Data.value('(/Sqm/Metrics/Metric/sum)[1]', 'varchar(max)') AS sum,
    Data.value('(/Sqm/Metrics/Metric/count)[1]', 'varchar(max)') AS count,
    Data.value('(/Sqm/Metrics/Metric/minValue)[1]', 'varchar(max)') AS minValue,
    Data.value('(/Sqm/Metrics/Metric/maxValue)[1]', 'varchar(max)') AS maxValue,
    Data.value('(/Sqm/Metrics/Metric/stdDeviation)[1]', 'varchar(max)') AS stdDeviation,
FROM Sqm

To me this is much less confusing than using the outer apply or cross apply.

I hope this helps someone else looking for a simpler solution!

Your error

InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

appears because you must call setRequestHeader after calling open. Simply move your setRequestHeader line below your open line (but before send):

xmlhttp.open("POST", url);
xmlhttp.setRequestHeader("x-filename", photoId);
xmlhttp.send(formData);

This is for someone who tried all the answers and still failed. Extending pierre's answer. If you are using animation, setting up the visibility to GONE or INVISIBLE or invalidate() will never work. Try out the below solution. `

btn2.getAnimation().setAnimationListener(new Animation.AnimationListener() {
     @Override
     public void onAnimationStart(Animation animation) {
     }
     @Override
     public void onAnimationEnd(Animation animation) {
         btn2.setVisibility(View.GONE);
         btn2.clearAnimation();
     }
     @Override
     public void onAnimationRepeat(Animation animation) {
     }
});

`

I tried all the solutions given above and none of them worked for me, I ensured that I have exact build types and product flavours in my library module and app module.

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Entity
@Table(name="empTable")
public class Employee implements Serializable{
private static final long serialVersionUID = 1L;
private int id;
private String empName;

List<Address> addList=new ArrayList<Address>();


@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="emp_id")
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getEmpName() {
    return empName;
}
public void setEmpName(String empName) {
    this.empName = empName;
}

@OneToMany(mappedBy="employee",cascade=CascadeType.ALL)
public List<Address> getAddList() {
    return addList;
}

public void setAddList(List<Address> addList) {
    this.addList = addList;
}
}

We have two entities Employee and Address with One to Many relationship.

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="address")
public class Address implements Serializable{

private static final long serialVersionUID = 1L;

private int address_id;
private String address;
Employee employee;

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
public int getAddress_id() {
    return address_id;
}
public void setAddress_id(int address_id) {
    this.address_id = address_id;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}

@ManyToOne
@JoinColumn(name="emp_id")
public Employee getEmployee() {
    return employee;
}
public void setEmployee(Employee employee) {
    this.employee = employee;
}
}

By this way we can implement inner join between two tables

import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;

public class Main {

public static void main(String[] args) {
    saveEmployee();

    retrieveEmployee();

}

private static void saveEmployee() {
    Employee employee=new Employee();
    Employee employee1=new Employee();
    Employee employee2=new Employee();
    Employee employee3=new Employee();

    Address address=new Address();
    Address address1=new Address();
    Address address2=new Address();
    Address address3=new Address();

    address.setAddress("1485,Sector 42 b");
    address1.setAddress("1485,Sector 42 c");
    address2.setAddress("1485,Sector 42 d");
    address3.setAddress("1485,Sector 42 a");

    employee.setEmpName("Varun");
    employee1.setEmpName("Krishan");
    employee2.setEmpName("Aasif");
    employee3.setEmpName("Dut");

    address.setEmployee(employee);
    address1.setEmployee(employee1);
    address2.setEmployee(employee2);
    address3.setEmployee(employee3);

    employee.getAddList().add(address);
    employee1.getAddList().add(address1);
    employee2.getAddList().add(address2);
    employee3.getAddList().add(address3);

    Session session=HibernateUtil.getSessionFactory().openSession();

    session.beginTransaction();

    session.save(employee);
    session.save(employee1);
    session.save(employee2);
    session.save(employee3);
    session.getTransaction().commit();
    session.close();
}

private static void retrieveEmployee() {
    try{

    String sqlQuery="select e from Employee e inner join e.addList";

    Session session=HibernateUtil.getSessionFactory().openSession();

    Query query=session.createQuery(sqlQuery);

    List<Employee> list=query.list();

     list.stream().forEach((p)->{System.out.println(p.getEmpName());});     
    session.close();
    }catch(Exception e){
        e.printStackTrace();
    }
}
}

I have used Java 8 for loop for priting the names. Make sure you have jdk 1.8 with tomcat 8. Also add some more records for better understanding.

 public class HibernateUtil {
 private static SessionFactory sessionFactory ;
 static {
    Configuration configuration = new Configuration();

    configuration.addAnnotatedClass(Employee.class);
    configuration.addAnnotatedClass(Address.class);
                  configuration.setProperty("connection.driver_class","com.mysql.jdbc.Driver");
    configuration.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:3306/hibernate");                                
    configuration.setProperty("hibernate.connection.username", "root");     
    configuration.setProperty("hibernate.connection.password", "root");
    configuration.setProperty("dialect", "org.hibernate.dialect.MySQLDialect");
    configuration.setProperty("hibernate.hbm2ddl.auto", "update");
    configuration.setProperty("hibernate.show_sql", "true");
    configuration.setProperty(" hibernate.connection.pool_size", "10");


   // configuration
    StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
    sessionFactory = configuration.buildSessionFactory(builder.build());
 }
public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
} 

This is a little longer than some but this is what I use to match IPv4 addresses. Simple with no compromises.

^((25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])\.){3}(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])$

The numpy_indexed package (disclaimer, I am its author) contains a vectorized equivalent of list.index for numpy.ndarray; that is:

sequence_of_arrays = [[0, 1], [1, 2], [-5, 0]]
arrays_to_query = [[-5, 0], [1, 0]]

import numpy_indexed as npi
idx = npi.indices(sequence_of_arrays, arrays_to_query, missing=-1)
print(idx)   # [2, -1]

This solution has vectorized performance, generalizes to ndarrays, and has various ways of dealing with missing values.

On IntelliJ IDEA platform you can use Java Decompiler IntelliJ Plugin. It allows you to display all the Java sources during your debugging process, even if you do not have them all. It is based on the famous tools JD-GUI.

To get all the lines of the file loaded into the variable, Delayed Expansion is needed, so do the following:

SETLOCAL EnableDelayedExpansion

for /f "Tokens=* Delims=" %%x in (version.txt) do set Build=!Build!%%x

There is a problem with some special characters, though especially ;, % and !

If you are using C function fgetc then you should check a next character whether it is equal to the new line character or to EOF. For example

unsigned int count = 0;
while ( 1 )
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
      if ( c == EOF ) break;
   }
   else
   {
      ++count;
   }
}    

or maybe it would be better to rewrite the code using do-while loop. For example

unsigned int count = 0;
do
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
   }
   else
   {
      ++count;
   }
} while ( c != EOF );

Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc to read lines of a file.

But if the program is written in C++ then it would be much better if you would use std::ifstream and std::string classes and function std::getline to read a whole line.

Well, you are using both frame.setSize() and frame.pack().

You should use one of them at one time.

Using setSize() you can give the size of frame you want but if you use pack(), it will automatically change the size of the frames according to the size of components in it. It will not consider the size you have mentioned earlier.

Try removing frame.pack() from your code or putting it before setting size and then run it.

document.getElementById('myframe1').contentWindow.document.getElementById('x')

Fiddle

contentWindow is supported by all browsers including the older versions of IE.

Note that if the iframe's src is from another domain, you won't be able to access its content due to the Same Origin Policy.

Just download this registry key and run it. It will add the necessary key to the .NET framework registry. You can have more info at this link. Search for 'Option 2' in '.NET 4.5 to 4.5.2'.

The reg file appends the following to the Registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

This is the part of the page that is useful in case it goes broken :

" .. enable TLS 1.2 by default without modifying the source code by setting the SchUseStrongCrypto DWORD value in the following two registry keys to 1, creating them if they don't exist: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319" and "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v4.0.30319". Although the version number in those registry keys is 4.0.30319, the .NET 4.5, 4.5.1, and 4.5.2 frameworks also use these values. Those registry keys, however, will enable TLS 1.2 by default in all installed .NET 4.0, 4.5, 4.5.1, and 4.5.2 applications on that system. It is thus advisable to test this change before deploying it to your production servers. This is also available as a registry import file. These registry values, however, will not affect .NET applications that set the System.Net.ServicePointManager.SecurityProtocol value. "

In addition to Cody's useful comments it is worth noting that at times you won't know how big your array should be. The two options in this situation are

1. Creating an array big enough to handle anything you think will be thrown at it
2. Sensible use of Redim Preserve

The code below provides an example of a routine that will dimension myArray in line with the lngSize variable, then add additional elements (equal to the initial array size) by use of a Mod test whenever the upper bound is about to be exceeded

Option Base 1

Sub ArraySample()
    Dim myArray() As String
    Dim lngCnt As Long
    Dim lngSize As Long

    lngSize = 10
    ReDim myArray(1 To lngSize)

    For lngCnt = 1 To lngSize*5
        If lngCnt Mod lngSize = 0 Then ReDim Preserve myArray(1 To UBound(myArray) + lngSize)
        myArray(lngCnt) = "I am record number " & lngCnt
    Next
End Sub

CellSpacing as the name suggests it is the Space between the Adjacent cells and CellPadding on the other hand means the padding around the cell content.

What format are you wanting the output?

If you're happy with a string then consider the following C# code:

double num = 3.12345;
num.ToString("G3");

The result will be "3.12".

This link might be of use if you're using .NET. http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx

I hope that helps....but unless you identify than language you are using and the format in which you want the output it is difficult to suggest an appropriate solution.

This will display the source code instead of executing it:

<VirtualHost *>
    ServerName sourcecode.testserver.me
    DocumentRoot /var/www/example
    AddType text/plain php
</VirtualHost>

I used it once to enable other co-worker to have read access to the source code from the local network (just a quick and dirty alternative).

WARNING !:

As Dan pointed it out sometime ago, this method should never be used in production. Please follow the accepted answer as it blocks any attempt to execute or display php files.

If you want users to share php files (and let others to display the source code), there are better ways to do it, like git, wiki, etc.

This method should be avoided! (you have been warned. Left it here for educational purposes)

Please add: CFLAGS="-lrt" and LDFLAGS="-lrt"

In xml edittext:

android:id="@+id/text"

In program:

EditText text=(EditText) findViewById(R.id.text);
text.setRawInputType(Configuration.KEYBOARDHIDDEN_YES);

You can use the IndexOf method and the Substring method like so:

string output = input.Substring(input.IndexOf('.') + 1);

The above doesn't have error handling, so if a period doesn't exist in the input string, it will present problems.

[self dismissModalViewControllerAnimated:NO]; has been deprecated.

Use [self dismissViewControllerAnimated:NO completion:nil]; instead.

enumerate() makes this prettier:

for index, value in enumerate(S):
    print index, value

This is add new string in the file

using (var file = new StreamWriter(filePath + "log.txt", true))
        {
            file.WriteLine(log);
            file.Close();
        }

the same problem also happened to me when i training my classification model. the reason caused this problem is as what the warning message said "in labels with no predicated samples", it will caused the zero-division when compute f1-score. I found another solution when i read sklearn.metrics.f1_score doc, there is a note as follows:

When true positive + false positive == 0, precision is undefined; When true positive + false negative == 0, recall is undefined. In such cases, by default the metric will be set to 0, as will f-score, and UndefinedMetricWarning will be raised. This behavior can be modified with zero_division

the zero_division default value is "warn", you could set it to 0 or 1 to avoid UndefinedMetricWarning. it works for me ;) oh wait, there is another problem when i using zero_division, my sklearn report that no such keyword argument by using scikit-learn 0.21.3. Just update your sklearn to the latest version by running pip install scikit-learn -U

I use a variation on JOP's answer. Using command line parameters you can set the debugging mode in the IDE with project properties or through the Windows service manager.

protected override void OnStart(string[] args)
{
  if (args.Contains<string>("DEBUG_SERVICE"))
  {
    Debugger.Break();
  }
  ...
}

<script language="javascript" type="text/javascript">
        function fixedlength(textboxID, keyEvent, maxlength) {
            //validation for digits upto 'maxlength' defined by caller function
            if (textboxID.value.length > maxlength) {
                textboxID.value = textboxID.value.substr(0, maxlength);
            }
            else if (textboxID.value.length < maxlength || textboxID.value.length == maxlength) {
                textboxID.value = textboxID.value.replace(/[^\d]+/g, '');
                return true;
            }
            else
                return false;
        }
 </script>

<asp:TextBox ID="txtNextVisit" runat="server" MaxLength="2" onblur="return fixedlength(this, event, 2);" onkeypress="return fixedlength(this, event, 2);" onkeyup="return fixedlength(this, event, 2);"></asp:TextBox> 

You can also do it in the "mathematical" way without treating the number as a string:

var num = 278;_x000D_
var digits = [];_x000D_
while (num > 0) {_x000D_
    digits.push(num % 10);_x000D_
    num = parseInt(num / 10);_x000D_
}_x000D_
digits.reverse();_x000D_
console.log(digits);

One upside I can see is that you won't have to run parseInt() on every digit, you're dealing with the actual digits as numeric values.

\d is called a character class and will match digits. It is equal to [0-9].

+ matches 1 or more occurrences of the character before.

So \d+ means match 1 or more digits.

In Internet Explorer, this solution does not work in ssl.

One can see the error in console as:

SEC7111: HTTPS security is compromised by this,

Workaround : As one of the user here suggested replace chart.apis.google.com to chart.googleapis.com for the URL path to avoid SSL error.

Here's a solution that uses more modern syntax and is less verbose than the ones already provided:

const canvas = document.querySelector("canvas");
const ctx = canvas.getContext("2d");
const video = document.querySelector("video");

video.addEventListener('play', () => {
  function step() {
    ctx.drawImage(video, 0, 0, canvas.width, canvas.height)
    requestAnimationFrame(step)
  }
  requestAnimationFrame(step);
})

Some useful links:

• MDN Documentation for window.requestAnimationFrame()
• Can I use requestAnimationFrame?

To be 32-bit and 64-bit safe, use one of the Boxed Expressions:

  label.text = [NSString stringWithFormat:@"%@", @(count).stringValue];

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Textarea autoresize</title>
    <style>
    textarea {
        overflow: hidden;
    }
    </style>
    <script>
    function resizeTextarea(ev) {
        this.style.height = '24px';
        this.style.height = this.scrollHeight + 12 + 'px';
    }

    var te = document.querySelector('textarea');
    te.addEventListener('input', resizeTextarea);
    </script>
</head>
<body>
    <textarea></textarea>
</body>
</html>

Tested in Firefox 14 and Chromium 18. The numbers 24 and 12 are arbitrary, test to see what suits you best.

You could do without the style and script tags, but it becomes a bit messy imho (this is old style HTML+JS and is not encouraged).

<textarea style="overflow: hidden" onkeyup="this.style.height='24px'; this.style.height = this.scrollHeight + 12 + 'px';"></textarea>

Edit: modernized code. Changed onkeyup attribute to addEventListener.
Edit: keydown works better than keyup
Edit: declare function before using
Edit: input works better than keydown (thnx @WASD42 & @MA-Maddin)

</table>
<input type='submit' class='buttons'>
</form>

Please note though, that only the values of only checked checkboxes will be sent.

If you are getting this error with a Java configuration, it is usually because you forget to pass in the application context to the DispatcherServlet constructor:

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet()); // <-- no constructor args!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

Fix it by adding the context as the constructor arg:

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet(ctx)); // <-- hooray! Spring doesn't look for XML files!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

With the Androidx library and Material Components Theme you can override the getTheme() method:

import androidx.fragment.app.DialogFragment

class RoundedDialog: DialogFragment() {

    override fun getTheme() = R.style.RoundedCornersDialog

    //....

}

with:

<style name="RoundedCornersDialog" parent="@style/Theme.MaterialComponents.Dialog">
    <item name="dialogCornerRadius">16dp</item>
</style>

Or you can use the MaterialAlertDialogBuilder included in the Material Components Library:

import androidx.fragment.app.DialogFragment
import com.google.android.material.dialog.MaterialAlertDialogBuilder

class RoundedAlertDialog : DialogFragment() {

    //...

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        return MaterialAlertDialogBuilder(requireActivity(), R.style.MaterialAlertDialog_rounded)
                .setTitle("Test")
                .setMessage("Message")
                .setPositiveButton("OK", null)
                .create()
    }

}

with:

<style name="MaterialAlertDialog_rounded" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <item name="shapeAppearanceOverlay">@style/DialogCorners</item>
</style>

<style name="DialogCorners">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">16dp</item>
</style>

If you don't need a DialogFragment just use the MaterialAlertDialogBuilder.

Is using System.Threading.Timer mandatory?

If not, System.Timers.Timer has handy Start() and Stop() methods (and an AutoReset property you can set to false, so that the Stop() is not needed and you simply call Start() after executing).

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

Something like this ought to do:

$url = preg_replace("|^.+?://|", "", $url);

I got this error when stubbing with sinon.

The fix is to use npm package sinon-as-promised when resolving or rejecting promises with stubs.

Instead of ...

sinon.stub(Database, 'connect').returns(Promise.reject( Error('oops') ))

Use ...

require('sinon-as-promised');
sinon.stub(Database, 'connect').rejects(Error('oops'));

There is also a resolves method (note the s on the end).

Rob Farley's blog post might be of help:

• Two ways to find / drop a default constraint without knowing its name

Something like:

 declare @table_name nvarchar(256)
 declare @col_name nvarchar(256)

 set @col_name = N'ModifiedDate'

 select t.name, c.name, d.name, d.definition
 from 
     sys.tables t
     join sys.default_constraints d on d.parent_object_id = t.object_id
     join sys.columns c on c.object_id = t.object_id
                           and c.column_id = d.parent_column_id
 where

You have to specify the folder where you are saving it and it has to exist, in other case it will throw an error.

var s = txt.CreateTextFile("c:\\11.txt", true);

I've changed the recursion to iteration.

def MovingTheBall(listOfBalls,position,numCell):
while 1:
    stop=1
    positionTmp = (position[0]+choice([-1,0,1]),position[1]+choice([-1,0,1]),0)
    for i in range(0,len(listOfBalls)):
        if positionTmp==listOfBalls[i].pos:
            stop=0
    if stop==1:
        if (positionTmp[0]==0 or positionTmp[0]>=numCell or positionTmp[0]<=-numCell or positionTmp[1]>=numCell or positionTmp[1]<=-numCell):
            stop=0
        else:
            return positionTmp

Works good :D

Firstly, try / except are not functions, but statements.

To convert a string (or any other type that can be converted) to an integer in Python, simply call the int() built-in function. int() will raise a ValueError if it fails and you should catch this specifically:

In Python 2.x:

>>> for value in '12345', 67890, 3.14, 42L, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print '%s as an int is %d' % (str(value), int(value))
...     except ValueError as ex:
...         print '"%s" cannot be converted to an int: %s' % (value, ex)
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

In Python 3.x

the syntax has changed slightly:

>>> for value in '12345', 67890, 3.14, 42, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print('%s as an int is %d' % (str(value), int(value)))
...     except ValueError as ex:
...         print('"%s" cannot be converted to an int: %s' % (value, ex))
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

I had a similar problem. I needed to get the last version of page content translation, in other words - to get that specific record which has highest number in version column. So I select all records ordered by version and then take the first row from result (by using LIMIT clause).

SELECT *
FROM `page_contents_translations`
ORDER BY version DESC
LIMIT 1

Personally I don't think we can find out an algorithm to calculate the most matched text color by specifying the background color.

I think currently the artist should have a list of color pairs which has good reading quality, we can add them to a table, and set one of these pairs randomly as our reading theme...

this is much reasonable, and we won't get ugly color pairs....

You can use Jinja's default:

- name: Create user
  user:
    name: "{{ my_variable | default('default_value') }}"

If you want to use familiar NSString, you can declare it explicitly:

var someString: NSString = "abcdefghi"

var someRange: NSRange = someString.rangeOfString("c")

I'm not sure yet how to do this in Swift.

Have you also tried following, it should work:

sudo chown <username> /dev/kvm
sudo chmod o+x /dev/kvm

The official length according to the offical Apache docs is 8,192, but many folks have run into trouble at ~4,000.

MS Internet Explorer is usually the limiting factor anyway, as it caps the maximum URL size at 2,048.

TRY THIS:

StringVariable=ByteVariable.decode('UTF-8','ignore')

TO TEST TYPE:

print(type(StringVariable))

Here 'StringVariable' represented as a string. 'ByteVariable' represent as Byte. Its not relevent to question Variables..

Based on the answer by @peteb, but using Promises and Async/Await:

const AWS = require('aws-sdk');

const s3 = new AWS.S3();

async function getObject (bucket, objectKey) {
  try {
    const params = {
      Bucket: bucket,
      Key: objectKey 
    }

    const data = await s3.getObject(params).promise();

    return data.Body.toString('utf-8');
  } catch (e) {
    throw new Error(`Could not retrieve file from S3: ${e.message}`)
  }
}

// To retrieve you need to use `await getObject()` or `getObject().then()`
getObject('my-bucket', 'path/to/the/object.txt').then(...);

I have this article bookmarked on setting this up for Java 5 and below.

Basically run it with:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044

For Java 5 and above, run it with:

-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=1044

Also you can use ss utility to dump sockets statistics.

To dump summary:

ss -s

Total: 91 (kernel 0)
TCP:   18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0

Transport Total     IP        IPv6
*         0         -         -        
RAW       0         0         0        
UDP       4         2         2        
TCP       18        16        2        
INET      22        18        4        
FRAG      0         0         0

To display all sockets:

ss -a

To display UDP sockets:

ss -u -a

To display TCP sockets:

ss -t -a

Here you can read ss man: ss

    $time = 00:06:00;
    $timeInSeconds = strtotime($time) - strtotime('TODAY');

All of these examples use an external module, but you can achieve the same result using just the datetime module, as also presented in this SO answer:

from datetime import datetime
from datetime import timezone

dt = datetime.now()
dt.replace(tzinfo=timezone.utc)

print(dt.replace(tzinfo=timezone.utc).isoformat())
'2017-01-12T22:11:31+00:00'

Fewer dependencies and no pytz issues.

NOTE: If you wish to use this with python3 and python2, you can use this as well for the timezone import (hardcoded for UTC):

try:
    from datetime import timezone
    utc = timezone.utc
except ImportError:
    #Hi there python2 user
    class UTC(tzinfo):
        def utcoffset(self, dt):
            return timedelta(0)
        def tzname(self, dt):
            return "UTC"
        def dst(self, dt):
            return timedelta(0)
    utc = UTC()

Ex5:

Reading multiple CSV files from multiple folders:

val folders = List("C:spark\\sample_data\\tmp", "C:spark\\sample_data\\tmp1")
val df = spark.read.option("header", "true").csv(folders: _*)

You may need to consider some further aspects for code robustness;

when you're storing an integer-valued variable as an environment variable, try

os.environ['DEBUSSY'] = str(myintvariable)

then for retrieval, consider that to avoid errors, you should try

os.environ.get('DEBUSSY', 'Not Set')

possibly substitute '-1' for 'Not Set'

so, to put that all together

myintvariable = 1
os.environ['DEBUSSY'] = str(myintvariable)
strauss = int(os.environ.get('STRAUSS', '-1'))
# NB KeyError <=> strauss = os.environ['STRAUSS']
debussy = int(os.environ.get('DEBUSSY', '-1'))

print "%s %u, %s %u" % ('Strauss', strauss, 'Debussy', debussy)

According to the docs numpy.loadtxt is

a fast reader for simply formatted files. The genfromtxt function provides more sophisticated handling of, e.g., lines with missing values.

so there are only a few options to handle more complicated files. As mentioned numpy.genfromtxt has more options. So as an example you could use

import numpy as np
data = np.genfromtxt('e:\dir1\datafile.csv', delimiter=',', skip_header=10,
                     skip_footer=10, names=['x', 'y', 'z'])

to read the data and assign names to the columns (or read a header line from the file with names=True) and than plot it with

ax1.plot(data['x'], data['y'], color='r', label='the data')

I think numpy is quite well documented now. You can easily inspect the docstrings from within ipython or by using an IDE like spider if you prefer to read them rendered as HTML.

Assign something to your strings. This will definitely help.

You can use from the pd.to_numeric(s)

jQuery 1.5 added deferred objects that handle this nicely. Simply call $.post and attach any handlers you'd like after the call. Deferred objects even allow you to attach multiple success and error handlers.

Example:

$.post('status.ajax.php', {deviceId: id})
    .done( function(msg) { ... } )
    .fail( function(xhr, textStatus, errorThrown) {
        alert(xhr.responseText);
    });

Prior to jQuery 1.8, the function done was called success and fail was called error.

DateTime.Parse

Syntax:

DateTime.Parse(String value)
DateTime.Parse(String value, IFormatProvider provider)
DateTime.Parse(String value, IFormatProvider provider, DateTypeStyles styles)

Example:

string value = "1 January 2019";
CultureInfo provider = new CultureInfo("en-GB");
DateTime.Parse(value, provider, DateTimeStyles.NoCurrentDateDefault););

• Value: string representation of date and time.
• Provider: object which provides culture specific info.
• Styles: formatting options that customize string parsing for some date and time parsing methods. For instance, AllowWhiteSpaces is a value which helps to ignore all spaces present in string while it parse.

It's also worth remembering DateTime is an object that is stored as number internally in the framework, Format only applies to it when you convert it back to string.

• Parsing converting a string to the internal number type.

• Formatting converting the internal numeric value to a readable string.

I recently had an issue where I was trying to convert a DateTime to pass to Linq what I hadn't realised at the time was format is irrelevant when passing DateTime to a Linq Query.

DateTime SearchDate = DateTime.Parse(searchDate);
applicationsUsages = applicationsUsages.Where(x => DbFunctions.TruncateTime(x.dateApplicationSelected) == SearchDate.Date);

The problem could be that we need to specifically give adb root access in the developnent options in the latest CMs.. Here is what i did.

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server * daemon not running. starting it now on port 5037 * * daemon started successfully * root access is disabled by system setting - enable in settings -> development options

after altering the development options...

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting adbd as root
abc@abc-L655:~$ adb shell
root@android:/ # ls /data/ .... good to go.. 

What is the difference between the following ways of handling InterruptedException? What is the best way to do it?

You've probably come to ask this question because you've called a method that throws InterruptedException.

First of all, you should see throws InterruptedException for what it is: A part of the method signature and a possible outcome of calling the method you're calling. So start by embracing the fact that an InterruptedException is a perfectly valid result of the method call.

Now, if the method you're calling throws such exception, what should your method do? You can figure out the answer by thinking about the following:

Does it make sense for the method you are implementing to throw an InterruptedException? Put differently, is an InterruptedException a sensible outcome when calling your method?

• If yes, then throws InterruptedException should be part of your method signature, and you should let the exception propagate (i.e. don't catch it at all).

  Example: Your method waits for a value from the network to finish the computation and return a result. If the blocking network call throws an InterruptedException your method can not finish computation in a normal way. You let the InterruptedException propagate.

  int computeSum(Server server) throws InterruptedException {
      // Any InterruptedException thrown below is propagated
      int a = server.getValueA();
      int b = server.getValueB();
      return a + b;
  }
  

• If no, then you should not declare your method with throws InterruptedException and you should (must!) catch the exception. Now two things are important to keep in mind in this situation:

  1. Someone interrupted your thread. That someone is probably eager to cancel the operation, terminate the program gracefully, or whatever. You should be polite to that someone and return from your method without further ado.

  2. Even though your method can manage to produce a sensible return value in case of an InterruptedException the fact that the thread has been interrupted may still be of importance. In particular, the code that calls your method may be interested in whether an interruption occurred during execution of your method. You should therefore log the fact an interruption took place by setting the interrupted flag: Thread.currentThread().interrupt()

  Example: The user has asked to print a sum of two values. Printing "Failed to compute sum" is acceptable if the sum can't be computed (and much better than letting the program crash with a stack trace due to an InterruptedException). In other words, it does not make sense to declare this method with throws InterruptedException.

  void printSum(Server server) {
       try {
           int sum = computeSum(server);
           System.out.println("Sum: " + sum);
       } catch (InterruptedException e) {
           Thread.currentThread().interrupt();  // set interrupt flag
           System.out.println("Failed to compute sum");
       }
  }
  

By now it should be clear that just doing throw new RuntimeException(e) is a bad idea. It isn't very polite to the caller. You could invent a new runtime exception but the root cause (someone wants the thread to stop execution) might get lost.

Other examples:

Implementing Runnable: As you may have discovered, the signature of Runnable.run does not allow for rethrowing InterruptedExceptions. Well, you signed up on implementing Runnable, which means that you signed up to deal with possible InterruptedExceptions. Either choose a different interface, such as Callable, or follow the second approach above.

Calling Thread.sleep: You're attempting to read a file and the spec says you should try 10 times with 1 second in between. You call Thread.sleep(1000). So, you need to deal with InterruptedException. For a method such as tryToReadFile it makes perfect sense to say, "If I'm interrupted, I can't complete my action of trying to read the file". In other words, it makes perfect sense for the method to throw InterruptedExceptions.

String tryToReadFile(File f) throws InterruptedException {
    for (int i = 0; i < 10; i++) {
        if (f.exists())
            return readFile(f);
        Thread.sleep(1000);
    }
    return null;
}

Class.forName()-->forName() is the static method of Class class it returns Class class object used for reflection not user class object so you can only call Class class methods on it like getMethods(), getConstructors() etc.

If you care about only running static block of your(Runtime given) class and only getting information of methods,constructors,Modifier etc of your class you can do with this object which you get using Class.forName()

But if you want to access or call your class method (class which you have given at runtime) then you need to have its object so newInstance method of Class class do it for you.It create new instance of the class and return it to you .You just need to type-cast it to your class.

ex-: suppose Employee is your class then

Class a=Class.forName(args[0]); 

//args[0]=cmd line argument to give class at  runtime. 

Employee ob1=a.newInstance();

a.newInstance() is similar to creating object using new Employee().

now you can access all your class visible fields and methods.

Use this:

var dict = list.ToDictionary(x => x);

See MSDN for more info.

As Pranay points out in the comments, this will fail if an item exists in the list multiple times.
Depending on your specific requirements, you can either use var dict = list.Distinct().ToDictionary(x => x); to get a dictionary of distinct items or you can use ToLookup instead:

var dict = list.ToLookup(x => x);

This will return an ILookup<string, string> which is essentially the same as IDictionary<string, IEnumerable<string>>, so you will have a list of distinct keys with each string instance under it.

In Swift use

mapView.showAnnotations(annotationArray, animated: true)

In Objective c

[mapView showAnnotations:annotationArray animated:YES];

map.get(myCode)

@Sheridan thx.. if I try your example with "DisplayedImagePath" on both sides, it works with absolute path as you show.

As for the relative paths, this is how I always connect relative paths, I first include the subdirectory (!) and the image file in my project.. then I use ~ character to denote the bin-path..

    public string DisplayedImagePath
    {
        get { return @"~\..\images\osc.png"; }
    }

This was tested, see below my Solution Explorer in VS2015..

)

Note: if you want a Click event, use the Button tag around the image,

<Button Click="image_Click" Width="128" Height="128"  Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Left">_x000D_
  <Image x:Name="image" Source="{Binding DisplayedImagePath}" Margin="0,0,0,0" />_x000D_
</Button>

Transfer is entirely server-side. Client address bar stays constant. Some complexity about the transfer of context between requests. Flushing and restarting page handlers can be expensive so do your transfer early in the pipeline e.g. in an HttpModule during BeginRequest. Read the MSDN docs carefully, and test and understand the new values of HttpContext.Request - especially in Postback scenarios. We usually use Server.Transfer for error scenarios.

Redirect terminates the request with a 302 status and client-side roundtrip response with and internally eats an exception (minor server perf hit - depends how many you do a day) Client then navigates to new address. Browser address bar & history updates etc. Client pays the cost of an extra roundtrip - cost varies depending on latency. In our business we redirect a lot we wrote our own module to avoid the exception cost.

Unfortunately I can't comment with my newbie reputation, but I have a solution for the issue of the screen going blank, or at least this is what worked for me. Instead of setting the wrapper class inside of the errorPlacement function, set it immediately when you're setting the wrapper type.

$('#myForm').validate({
    errorElement: "div",
    wrapper: "div class=\"message\"",
    errorPlacement: function(error, element) {
        offset = element.offset();
        error.insertBefore(element);
        //error.addClass('message');  // add a class to the wrapper
        error.css('position', 'absolute');
        error.css('left', offset.left + element.outerWidth() + 5);
        error.css('top', offset.top - 3);
    }

});

I'm assuming doing it this way allows the validator to know which div elements to remove, instead of all of them. Worked for me but I'm not entirely sure why, so if someone could elaborate that might help others out a ton.

there are four types of strings available in php. They are single quotes ('), double quotes (") and Nowdoc (<<<'EOD') and heredoc(<<<EOD) strings

you can use both single quotes and double quotes inside heredoc string. Variables will be expanded just as double quotes.

nowdoc strings will not expand variables just like single quotes.

ref: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc

I have seen people use Throwable to catch some errors that might happen due to infra failure/ non availability.

Make sure when you create a txt file you don't type in the name "name.txt", just type in "name". If you type "name.txt" Eclipse will see it as "name.txt.txt". This solved it for me. Also save the file in the src folder, not the folder were the .java resides, one folder up.

As of 2018,

use MiniCssExtractPlugin

for Webpack(> 4.0) will solve this problem.

https://github.com/webpack-contrib/mini-css-extract-plugin

Using extract-text-webpack-plugin in the accepted answer is NOT recommended for Webpack 4.0+.

In a Python 2 program that I used for many years there was this line:

ocd[i].namn=unicode(a[:b], 'utf-8')

This did not work in Python 3.

However, the program turned out to work with:

ocd[i].namn=a[:b]

I don't remember why I put unicode there in the first place, but I think it was because the name can contains Swedish letters åäöÅÄÖ. But even they work without "unicode".

Simply pass the BSTR directly to the wstring constructor, it is compatible with a wchar_t*:

BSTR btest = SysAllocString(L"Test");
assert(btest != NULL);
std::wstring wtest(btest);
assert(0 == wcscmp(wtest.c_str(), btest));

Converting BSTR to std::string requires a conversion to char* first. That's lossy since BSTR stores a utf-16 encoded Unicode string. Unless you want to encode in utf-8. You'll find helper methods to do this, as well as manipulate the resulting string, in the ICU library.

Have you tried using the !important flag on the style? !important allows you to decide which style will win out. Also note !important will override inline styles as well.

#example p {
    color: blue !important;
}
...
#example p {
    color: red;
}

Another couple suggestions:

Add a span inside of the current. The inner most will win out. Although this could get pretty ugly.

<span class="style21">
<span style="position:absolute;top:432px;left:422px; color:Red" >relating to</span>
</span>

jQuery is also an option. The jQuery library will inject the style attribute in the targeted element.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js" type="text/javascript" ></script>
    <script type="text/javascript">

        $(document).ready(function() {
            $("span").css("color", "#ff0000");
        });

    </script>

Hope this helps. CSS can be pretty frustrating at times.
