Since I don't have a high enough reputation to comment I'll answer liang question on Feb 20 at 10:01 as an answer to the original question.

In order for the for the line labels to show you need to add plt.legend to your code. to build on the previous example above that also includes title, ylabel and xlabel:

import matplotlib.pyplot as plt

plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.title('title')
plt.ylabel('ylabel')
plt.xlabel('xlabel')
plt.legend()
plt.show()

UPDATE For Android v19+ see this link via @Sandra

You can create your own animations. Place animation XML files in res > anim

enter_from_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="-100%p" android:toXDelta="0%"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

enter_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="100%p" android:toXDelta="0%"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

exit_to_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="0%" android:toXDelta="-100%p"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

exit_to_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="0%" android:toXDelta="100%p"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

you can change the duration to short animation time

android:duration="@android:integer/config_shortAnimTime"

or long animation time

android:duration="@android:integer/config_longAnimTime" 

USAGE (note that the order in which you call methods on the transaction matters. Add the animation before you call .replace, .commit):

FragmentTransaction transaction = supportFragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
transaction.replace(R.id.content_frame, fragment);
transaction.addToBackStack(null);
transaction.commit();

Alternatively, you could invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

I liked this example.

Here is a different approach using mix-blend-mode: difference, that will actually invert whatever the background is, not just a single colour:

div {_x000D_
  background-image: linear-gradient(to right, red, yellow, green, cyan, blue, violet);_x000D_
}_x000D_
p {_x000D_
  color: white;_x000D_
  mix-blend-mode: difference;_x000D_
}

<div>_x000D_
  <p>Lorem ipsum dolor sit amet, consectetur adipiscit elit, sed do</p>_x000D_
</div>

To add to tacaswell's answer, the colorbar() function has an optional cax input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')

cax.set_xlabel('data label')  # cax == cb.ax

Use

ax.xaxis.tick_top()

to place the tick marks at the top of the image. The command

ax.set_xlabel('X LABEL')    
ax.xaxis.set_label_position('top') 

affects the label, not the tick marks.

import matplotlib.pyplot as plt
import numpy as np
column_labels = list('ABCD')
row_labels = list('WXYZ')
data = np.random.rand(4, 4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data, cmap=plt.cm.Blues)

# put the major ticks at the middle of each cell
ax.set_xticks(np.arange(data.shape[1]) + 0.5, minor=False)
ax.set_yticks(np.arange(data.shape[0]) + 0.5, minor=False)

# want a more natural, table-like display
ax.invert_yaxis()
ax.xaxis.tick_top()

ax.set_xticklabels(column_labels, minor=False)
ax.set_yticklabels(row_labels, minor=False)
plt.show()

Can be done in major new broswers using the code below

.img {
    -webkit-filter:invert(100%);
     filter:progid:DXImageTransform.Microsoft.BasicImage(invert='1');
}

However, if you want it to work across all browsers you need to use Javascript. Something like this gist will do the job.

I finally solved this problem, at least with Safari, by putting "pointer-events: auto" before "disabled". The reverse order didn't work.

So the solution depend on whether you adjust the subplot. If you specify plt.subplots_adjust (top, bottom, right, left), you don't want to use the kwargs of bbox_inches='tight' with plt.savefig, as it paradoxically creates whitespace padding. It also allows you to save the image as the same dims as the input image (600x600 input image saves as 600x600 pixel output image).

If you don't care about the output image size consistency, you can omit the plt.subplots_adjust attributes and just use the bbox_inches='tight' and pad_inches=0 kwargs with plt.savefig.

This solution works for matplotlib versions 3.0.1, 3.0.3 and 3.2.1. It also works when you have more than 1 subplot (eg. plt.subplots(2,2,...).

def save_inp_as_output(_img, c_name, dpi=100):
    h, w, _ = _img.shape
    fig, axes = plt.subplots(figsize=(h/dpi, w/dpi))
    fig.subplots_adjust(top=1.0, bottom=0, right=1.0, left=0, hspace=0, wspace=0) 
    axes.imshow(_img)
    axes.axis('off')
    plt.savefig(c_name, dpi=dpi, format='jpeg') 

Try this code. This does what you want.

Another difference between them is the size of the file:

• Mustache.js has 9kb,
• Handlebars.js has 86kb, or 18kb if using precompiled templates.

To see the performance benefits of Handlebars.js we must use precompiled templates.

At the time the compiler encounters the call to swapCase in main(), it does not know about the function swapCase, so it reports an error. You can either move the definition of swapCase above main, or declare swap case above main:

void swapCase(char* name);

Also, the 32 in swapCase causes the reader to pause and wonder. The comment helps! In this context, it would add clarity to write

if ('A' <= name[i] && name[i] <= 'Z')
    name[i] += 'a' - 'A';
else if ('a' <= name[i] && name[i] <= 'z')
    name[i] += 'A' - 'a';

The construction in my if-tests is a matter of personal style. Yours were just fine. The main thing is the way to modify name[i] -- using the difference in 'a' vs. 'A' makes it more obvious what is going on, and nobody has to wonder if the '32' is actually correct.

Good luck learning!

As for this question, I'd say the wiki has already provided detailed and easy-understanding explanations. I will just quote the most significant here.

Implementation of IoC

In object-oriented programming, there are several basic techniques to implement inversion of control. These are:

1. Using a service locator pattern Using dependency injection, for example Constructor injection Parameter injection Setter injection Interface injection;
2. Using a contextualized lookup;
3. Using template method design pattern;
4. Using strategy design pattern

As for Dependency Injection

dependency injection is a technique whereby one object (or static method) supplies the dependencies of another object. A dependency is an object that can be used (a service). An injection is the passing of a dependency to a dependent object (a client) that would use it.

 grep "subscription" | grep -v "spec"  

Maybe the most concise way:

$ awk '{$(NF+1)=$1;$1=""}sub(FS,"")' infile
United Arab Emirates AE
Antigua & Barbuda AG
Netherlands Antilles AN
American Samoa AS
Bosnia and Herzegovina BA
Burkina Faso BF
Brunei Darussalam BN

Explanation:

$(NF+1)=$1: Generator of a "new" last field.

$1="": Set the original first field to null

sub(FS,""): After the first two actions {$(NF+1)=$1;$1=""} get rid of the first field separator by using sub. The final print is implicit.

Extension method based on Linq

public static void DeleteRows(this DataTable dt, Func<DataRow, bool> predicate)
{
    foreach (var row in dt.Rows.Cast<DataRow>().Where(predicate).ToList())
        row.Delete();
}

Then use:

DataTable dt = GetSomeData();
dt.DeleteRows(r => r.Field<double>("Amount") > 123.12 && r.Field<string>("ABC") == "XYZ");

Based on Daniel's answer, I think I've got something that works:

^(.(?!test))*$

The key is that you need to make the negative assertion on every character in the string

I was looking for a more general answer, but could not find it. I wrote a converter that might help others.

It is based on the fact that we need to distinguish six different cases:

• True 2 Visible, False 2 Hidden
• True 2 Visible, False 2 Collapsed
• True 2 Hidden, False 2 Visible
• True 2 Collapsed, False 2 Visible
• True 2 Hidden, False 2 Collapsed
• True 2 Collapsed, False 2 Hidden

Here is my implementation for the first 4 cases:

[ValueConversion(typeof(bool), typeof(Visibility))]
public class BooleanToVisibilityConverter : IValueConverter
{
    enum Types
    {
        /// <summary>
        /// True to Visible, False to Collapsed
        /// </summary>
        t2v_f2c,
        /// <summary>
        /// True to Visible, False to Hidden
        /// </summary>
        t2v_f2h,
        /// <summary>
        /// True to Collapsed, False to Visible
        /// </summary>
        t2c_f2v,
        /// <summary>
        /// True to Hidden, False to Visible
        /// </summary>
        t2h_f2v,
    }
    public object Convert(object value, Type targetType,
                          object parameter, CultureInfo culture)
    {
        var b = (bool)value;
        string p = (string)parameter;
        var type = (Types)Enum.Parse(typeof(Types), (string)parameter);
        switch (type)
        {
            case Types.t2v_f2c:
                return b ? Visibility.Visible : Visibility.Collapsed; 
            case Types.t2v_f2h:
                return b ? Visibility.Visible : Visibility.Hidden; 
            case Types.t2c_f2v:
                return b ? Visibility.Collapsed : Visibility.Visible; 
            case Types.t2h_f2v:
                return b ? Visibility.Hidden : Visibility.Visible; 
        }
        throw new NotImplementedException();
    }

    public object ConvertBack(object value, Type targetType,
        object parameter, CultureInfo culture)
    {
        var v = (Visibility)value;
        string p = (string)parameter;
        var type = (Types)Enum.Parse(typeof(Types), (string)parameter);
        switch (type)
        {
            case Types.t2v_f2c:
                if (v == Visibility.Visible)
                    return true;
                else if (v == Visibility.Collapsed)
                    return false;
                break;
            case Types.t2v_f2h:
                if (v == Visibility.Visible)
                    return true;
                else if (v == Visibility.Hidden)
                    return false;
                break;
            case Types.t2c_f2v:
                if (v == Visibility.Visible)
                    return false;
                else if (v == Visibility.Collapsed)
                    return true;
                break;
            case Types.t2h_f2v:
                if (v == Visibility.Visible)
                    return false;
                else if (v == Visibility.Hidden)
                    return true;
                break;
        }
        throw new InvalidOperationException();
    }
}

example:

Visibility="{Binding HasItems, Converter={StaticResource BooleanToVisibilityConverter}, ConverterParameter='t2v_f2c'}"

I think the parameters are easy to remember.

Hope it helps somebody.

Try this for python 2.7/3.x

inv_map={};
for i in my_map:
    inv_map[my_map[i]]=i    
print inv_map

There are a lot of insightful answers there already, but still, I would to direct to a slightly different situation: Instead of precondition, that should be put on top of a function indeed, think of a step-by-step initialization, where you have to check for each step to succeed and then continue with the next. In this case, you cannot check everything at the top.

I found my code really unreadable when writing an ASIO host application with Steinberg's ASIOSDK, as I followed the nesting paradigm. It went like eight levels deep, and I cannot see a design flaw there, as mentioned by Andrew Bullock above. Of course, I could have packed some inner code to another function, and then nested the remaining levels there to make it more readable, but this seems rather random to me.

By replacing nesting with guard clauses, I even discovered a misconception of mine regarding a portion of cleanup-code that should have occurred much earlier within the function instead of at the end. With nested branches, I would never have seen that, you could even say they led to my misconception.

So this might be another situation where inverted ifs can contribute to a clearer code.

The answers are perfect for adjust map boundaries for markers but if you like to expand Google Maps boundaries for shapes like polygons and circles, you can use following codes:

For Circles

bounds.union(circle.getBounds());

For Polygons

polygon.getPaths().forEach(function(path, index)
{
    var points = path.getArray();
    for(var p in points) bounds.extend(points[p]);
});

For Rectangles

bounds.union(overlay.getBounds());

For Polylines

var path = polyline.getPath();

var slat, blat = path.getAt(0).lat();
var slng, blng = path.getAt(0).lng();

for(var i = 1; i < path.getLength(); i++)
{
    var e = path.getAt(i);
    slat = ((slat < e.lat()) ? slat : e.lat());
    blat = ((blat > e.lat()) ? blat : e.lat());
    slng = ((slng < e.lng()) ? slng : e.lng());
    blng = ((blng > e.lng()) ? blng : e.lng());
}

bounds.extend(new google.maps.LatLng(slat, slng));
bounds.extend(new google.maps.LatLng(blat, blng));

Well, the best way is to use the following constructor:

template<class InputIterator> string (InputIterator begin, InputIterator end);

which would lead to something like:

std::vector<char> v;
std::string str(v.begin(), v.end());

git rm --cached *.FileExtension

This must ignore all files from this extension

This refers to the object you’re “in” right now. In other words,this refers to the receiving object. You use this to clarify which variable you’re referring to.Java_whitepaper page :37

class Point extends Object
{
    public double x;
    public double y;

    Point()
    {
        x = 0.0;
        y = 0.0;
    }

    Point(double x, double y)
    {
        this.x = x;
        this.y = y;
    }
}

In the above example code this.x/this.y refers to current class that is Point class x and y variables where (double x,double y) are double values passed from different class to assign values to current class .

There could be one of the following reasons:

1. You need make an entry in the Amazon Security Group to allow remote access from your machine to Amazon EC2 instance. :- I believe this is done by you as from your question it seems like you already made an entry with 0.0.0.0, which allows everybody to access the machine.
2. MySQL not allowing user to connect from remote machine:- By default MySql creates root user id with admin access. But root id's access is limited to localhost only. This means that root user id with correct password will not work if you try to access MySql from a remote machine. To solve this problem, you need to allow either the root user or some other DB user to access MySQL from remote machine. I would not recommend allowing root user id accessing DB from remote machine. You can use wildcard character % to specify any remote machine.
3. Check if machine's local firewall is not enabled. And if its enabled then make sure that port 3306 is open.

Use the MV* Pattern

Based on the example you attached, It's better in angular to use the following tools:

• ng-click - evaluates the expression when the element is clicked (Read More)
• ng-class - place a class based on the a given boolean expression (Read More)

for example:

<button ng-click="enabled=true">Click Me!</button>

<div ng-class="{'alpha':enabled}"> 
    ...
</div>

This gives you an easy way to decouple your implementation. e.g. you don't have any dependency between the div and the button.

Read this to learn about the MV* Pattern

You can create a timeoutPromise wrapper

function timeoutPromise(timeout, err, promise) {
  return new Promise(function(resolve,reject) {
    promise.then(resolve,reject);
    setTimeout(reject.bind(null,err), timeout);
  });
}

You can then wrap any promise

timeoutPromise(100, new Error('Timed Out!'), fetch(...))
  .then(...)
  .catch(...)  

It won't actually cancel an underlying connection but will allow you to timeout a promise.
Reference

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

 public class Itemfound{ 
        public static void main(String args[]){

                if( Arrays.asList("a","b","c").contains("a"){
                      System.out.println("It is here");
         }
    }

}

This is what you looking for. The contains() method simply checks the index of element in the list. If the index is greater than '0' than element is present in the list.

public boolean contains(Object o) {
return indexOf(o) >= 0;
}

BEGIN
  FOR r IN (select sid,serial# from v$session where username='user')
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid  || ',' || r.serial# || '''';
  END LOOP;
END;
/

It works for me.

ocw.mit.edu is a great resource that has helped me a bunch. randi is the best option, but if your into number fun try using the floor function with rand to get what you want.

I drew a number line and came up with

floor(rand*8) + 13

Command Line Interface Scala Toolkit (CLIST)

here is mine too! (a bit late in the game though)

https://github.com/backuity/clist

As opposed to scopt it is entirely mutable... but wait! That gives us a pretty nice syntax:

class Cat extends Command(description = "concatenate files and print on the standard output") {

  // type-safety: members are typed! so showAll is a Boolean
  var showAll        = opt[Boolean](abbrev = "A", description = "equivalent to -vET")
  var numberNonblank = opt[Boolean](abbrev = "b", description = "number nonempty output lines, overrides -n")

  // files is a Seq[File]
  var files          = args[Seq[File]](description = "files to concat")
}

And a simple way to run it:

Cli.parse(args).withCommand(new Cat) { case cat =>
    println(cat.files)
}

You can do a lot more of course (multi-commands, many configuration options, ...) and has no dependency.

I'll finish with a kind of distinctive feature, the default usage (quite often neglected for multi commands):

I needed to get the last id way after inserting it, so

$lastid = $wpdb->insert_id;

Was not an option.

Did the follow:

global $wpdb;
$id = $wpdb->get_var( 'SELECT id FROM ' . $wpdb->prefix . 'table' . ' ORDER BY id DESC LIMIT 1');

I do tend to use static classes for factories. For example, this is the logging class in one of my projects:

public static class Log
{
   private static readonly ILoggerFactory _loggerFactory =
      IoC.Resolve<ILoggerFactory>();

   public static ILogger For<T>(T instance)
   {
      return For(typeof(T));
   }

   public static ILogger For(Type type)
   {
      return _loggerFactory.GetLoggerFor(type);
   }
}

You might have even noticed that IoC is called with a static accessor. Most of the time for me, if you can call static methods on a class, that's all you can do so I mark the class as static for extra clarity.

I use SendEmail, which was created for this scenario. It's packaged for Ubuntu so I assume it's available

Open downloads.php from rootfile.

Then go to line 186 and change it to the following:

        if(preg_match("/\.jpg|\.gif|\.png|\.jpeg/i", $name)){
            $mime = getimagesize($download_location);
            if(!empty($mime)) {
                header("Content-Type: {$mime['mime']}");
            }
        }
        elseif(preg_match("/\.pdf/i", $name)){
            header("Content-Type: application/force-download");
            header("Content-type: application/pdf");
            header("Content-Disposition: inline; filename=\"".$name."\";");
        }

        else{
            header("Content-Type: application/force-download");
            header("Content-type: application/octet-stream");
            header("Content-Disposition: attachment; filename=\"".$name."\";");
        }

I use this command for simple rotate a file:

mv output.log `date +%F`-output.log

In local folder I have 2019-09-25-output.log

Make sure that your package is installed in your $GOPATH directory or already inside your workspace/package.

For example: if your $GOPATH = "c:\go", make sure that the package inside C:\Go\src\pkgName

I would propose changing the function declaration as follows so you can do what you want:

function foo($blah, $x = null, $y = null) {
    if (null === $x) {
        $x = "some value";
    }

    if (null === $y) {
        $y = "some other value";
    }

    code here!

}

This way, you can make a call like foo('blah', null, 'non-default y value'); and have it work as you want, where the second parameter $x still gets its default value.

With this method, passing a null value means you want the default value for one parameter when you want to override the default value for a parameter that comes after it.

As stated in other answers,

default parameters only work as the last arguments to the function. If you want to declare the default values in the function definition, there is no way to omit one parameter and override one following it.

If I have a method that can accept varying numbers of parameters, and parameters of varying types, I often declare the function similar to the answer shown by Ryan P.

Here is another example (this doesn't answer your question, but is hopefully informative:

public function __construct($params = null)
{
    if ($params instanceof SOMETHING) {
        // single parameter, of object type SOMETHING
    } elseif (is_string($params)) {
        // single argument given as string
    } elseif (is_array($params)) {
        // params could be an array of properties like array('x' => 'x1', 'y' => 'y1')
    } elseif (func_num_args() == 3) {
        $args = func_get_args();

        // 3 parameters passed
    } elseif (func_num_args() == 5) {
        $args = func_get_args();
        // 5 parameters passed
    } else {
        throw new \InvalidArgumentException("Could not figure out parameters!");
    }
}

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
   alert(str2 + " found");
}

I'm not sure that there isn't a bit too much fussing around here. I recently had problems with md5 and files stored as blobs on MySQL so I experimented with various file sizes and the straightforward Python approach, viz:

FileHash=hashlib.md5(FileData).hexdigest()

I could detect no noticeable performance difference with a range of file sizes 2Kb to 20Mb and therefore no need to 'chunk' the hashing. Anyway, if Linux has to go to disk, it will probably do it at least as well as the average programmer's ability to keep it from doing so. As it happened, the problem was nothing to do with md5. If you're using MySQL, don't forget the md5() and sha1() functions already there.

I would suggest reading PEP 483 and PEP 484 and watching this presentation by Guido on type hinting.

In a nutshell: Type hinting is literally what the words mean. You hint the type of the object(s) you're using.

Due to the dynamic nature of Python, inferring or checking the type of an object being used is especially hard. This fact makes it hard for developers to understand what exactly is going on in code they haven't written and, most importantly, for type checking tools found in many IDEs (PyCharm and PyDev come to mind) that are limited due to the fact that they don't have any indicator of what type the objects are. As a result they resort to trying to infer the type with (as mentioned in the presentation) around 50% success rate.

To take two important slides from the type hinting presentation:

Why type hints?

1. Helps type checkers: By hinting at what type you want the object to be the type checker can easily detect if, for instance, you're passing an object with a type that isn't expected.
2. Helps with documentation: A third person viewing your code will know what is expected where, ergo, how to use it without getting them TypeErrors.
3. Helps IDEs develop more accurate and robust tools: Development Environments will be better suited at suggesting appropriate methods when know what type your object is. You have probably experienced this with some IDE at some point, hitting the . and having methods/attributes pop up which aren't defined for an object.

Why use static type checkers?

• Find bugs sooner: This is self-evident, I believe.
• The larger your project the more you need it: Again, makes sense. Static languages offer a robustness and control that dynamic languages lack. The bigger and more complex your application becomes the more control and predictability (from a behavioral aspect) you require.
• Large teams are already running static analysis: I'm guessing this verifies the first two points.

As a closing note for this small introduction: This is an optional feature and, from what I understand, it has been introduced in order to reap some of the benefits of static typing.

You generally do not need to worry about it and definitely don't need to use it (especially in cases where you use Python as an auxiliary scripting language). It should be helpful when developing large projects as it offers much needed robustness, control and additional debugging capabilities.

Type hinting with mypy:

In order to make this answer more complete, I think a little demonstration would be suitable. I'll be using mypy, the library which inspired Type Hints as they are presented in the PEP. This is mainly written for anybody bumping into this question and wondering where to begin.

Before I do that let me reiterate the following: PEP 484 doesn't enforce anything; it is simply setting a direction for function annotations and proposing guidelines for how type checking can/should be performed. You can annotate your functions and hint as many things as you want; your scripts will still run regardless of the presence of annotations because Python itself doesn't use them.

Anyways, as noted in the PEP, hinting types should generally take three forms:

• Function annotations (PEP 3107).
• Stub files for built-in/user modules.
• Special # type: type comments that complement the first two forms. (See: What are variable annotations? for a Python 3.6 update for # type: type comments)

Additionally, you'll want to use type hints in conjunction with the new typing module introduced in Py3.5. In it, many (additional) ABCs (abstract base classes) are defined along with helper functions and decorators for use in static checking. Most ABCs in collections.abc are included, but in a generic form in order to allow subscription (by defining a __getitem__() method).

For anyone interested in a more in-depth explanation of these, the mypy documentation is written very nicely and has a lot of code samples demonstrating/describing the functionality of their checker; it is definitely worth a read.

Function annotations and special comments:

First, it's interesting to observe some of the behavior we can get when using special comments. Special # type: type comments can be added during variable assignments to indicate the type of an object if one cannot be directly inferred. Simple assignments are generally easily inferred but others, like lists (with regard to their contents), cannot.

Note: If we want to use any derivative of containers and need to specify the contents for that container we must use the generic types from the typing module. These support indexing.

# Generic List, supports indexing.
from typing import List

# In this case, the type is easily inferred as type: int.
i = 0

# Even though the type can be inferred as of type list
# there is no way to know the contents of this list.
# By using type: List[str] we indicate we want to use a list of strings.
a = []  # type: List[str]

# Appending an int to our list
# is statically not correct.
a.append(i)

# Appending a string is fine.
a.append("i")

print(a)  # [0, 'i']

If we add these commands to a file and execute them with our interpreter, everything works just fine and print(a) just prints the contents of list a. The # type comments have been discarded, treated as plain comments which have no additional semantic meaning.

By running this with mypy, on the other hand, we get the following response:

(Python3)jimmi@jim: mypy typeHintsCode.py
typesInline.py:14: error: Argument 1 to "append" of "list" has incompatible type "int"; expected "str"

Indicating that a list of str objects cannot contain an int, which, statically speaking, is sound. This can be fixed by either abiding to the type of a and only appending str objects or by changing the type of the contents of a to indicate that any value is acceptable (Intuitively performed with List[Any] after Any has been imported from typing).

Function annotations are added in the form param_name : type after each parameter in your function signature and a return type is specified using the -> type notation before the ending function colon; all annotations are stored in the __annotations__ attribute for that function in a handy dictionary form. Using a trivial example (which doesn't require extra types from the typing module):

def annotated(x: int, y: str) -> bool:
    return x < y

The annotated.__annotations__ attribute now has the following values:

{'y': <class 'str'>, 'return': <class 'bool'>, 'x': <class 'int'>}

If we're a complete newbie, or we are familiar with Python 2.7 concepts and are consequently unaware of the TypeError lurking in the comparison of annotated, we can perform another static check, catch the error and save us some trouble:

(Python3)jimmi@jim: mypy typeHintsCode.py
typeFunction.py: note: In function "annotated":
typeFunction.py:2: error: Unsupported operand types for > ("str" and "int")

Among other things, calling the function with invalid arguments will also get caught:

annotated(20, 20)

# mypy complains:
typeHintsCode.py:4: error: Argument 2 to "annotated" has incompatible type "int"; expected "str"

These can be extended to basically any use case and the errors caught extend further than basic calls and operations. The types you can check for are really flexible and I have merely given a small sneak peak of its potential. A look in the typing module, the PEPs or the mypy documentation will give you a more comprehensive idea of the capabilities offered.

Stub files:

Stub files can be used in two different non mutually exclusive cases:

• You need to type check a module for which you do not want to directly alter the function signatures
• You want to write modules and have type-checking but additionally want to separate annotations from content.

What stub files (with an extension of .pyi) are is an annotated interface of the module you are making/want to use. They contain the signatures of the functions you want to type-check with the body of the functions discarded. To get a feel of this, given a set of three random functions in a module named randfunc.py:

def message(s):
    print(s)

def alterContents(myIterable):
    return [i for i in myIterable if i % 2 == 0]

def combine(messageFunc, itFunc):
    messageFunc("Printing the Iterable")
    a = alterContents(range(1, 20))
    return set(a)

We can create a stub file randfunc.pyi, in which we can place some restrictions if we wish to do so. The downside is that somebody viewing the source without the stub won't really get that annotation assistance when trying to understand what is supposed to be passed where.

Anyway, the structure of a stub file is pretty simplistic: Add all function definitions with empty bodies (pass filled) and supply the annotations based on your requirements. Here, let's assume we only want to work with int types for our Containers.

# Stub for randfucn.py
from typing import Iterable, List, Set, Callable

def message(s: str) -> None: pass

def alterContents(myIterable: Iterable[int])-> List[int]: pass

def combine(
    messageFunc: Callable[[str], Any],
    itFunc: Callable[[Iterable[int]], List[int]]
)-> Set[int]: pass

The combine function gives an indication of why you might want to use annotations in a different file, they some times clutter up the code and reduce readability (big no-no for Python). You could of course use type aliases but that sometime confuses more than it helps (so use them wisely).

This should get you familiarized with the basic concepts of type hints in Python. Even though the type checker used has been mypy you should gradually start to see more of them pop-up, some internally in IDEs (PyCharm,) and others as standard Python modules.

I'll try and add additional checkers/related packages in the following list when and if I find them (or if suggested).

Checkers I know of:

• Mypy: as described here.
• PyType: By Google, uses different notation from what I gather, probably worth a look.

Related Packages/Projects:

• typeshed: Official Python repository housing an assortment of stub files for the standard library.

The typeshed project is actually one of the best places you can look to see how type hinting might be used in a project of your own. Let's take as an example the __init__ dunders of the Counter class in the corresponding .pyi file:

class Counter(Dict[_T, int], Generic[_T]):
        @overload
        def __init__(self) -> None: ...
        @overload
        def __init__(self, Mapping: Mapping[_T, int]) -> None: ...
        @overload
        def __init__(self, iterable: Iterable[_T]) -> None: ...

Where _T = TypeVar('_T') is used to define generic classes. For the Counter class we can see that it can either take no arguments in its initializer, get a single Mapping from any type to an int or take an Iterable of any type.

Notice: One thing I forgot to mention was that the typing module has been introduced on a provisional basis. From PEP 411:

A provisional package may have its API modified prior to "graduating" into a "stable" state. On one hand, this state provides the package with the benefits of being formally part of the Python distribution. On the other hand, the core development team explicitly states that no promises are made with regards to the the stability of the package's API, which may change for the next release. While it is considered an unlikely outcome, such packages may even be removed from the standard library without a deprecation period if the concerns regarding their API or maintenance prove well-founded.

So take things here with a pinch of salt; I'm doubtful it will be removed or altered in significant ways, but one can never know.

^** Another topic altogether, but valid in the scope of type-hints: PEP 526: Syntax for Variable Annotations is an effort to replace # type comments by introducing new syntax which allows users to annotate the type of variables in simple varname: type statements.

See What are variable annotations?, as previously mentioned, for a small introduction to these.

// array of $ids that you need to select
$ids = array('1', '2', '3', '4', '5', '6', '7', '8');

// create sql part for IN condition by imploding comma after each id
$in = '(' . implode(',', $ids) .')';

// create sql
$sql = 'SELECT * FROM products WHERE catid IN ' . $in;

// see what you get
var_dump($sql);

Update: (a short version and update missing comma)

$ids = array('1','2','3','4');
$sql = 'SELECT * FROM products WHERE catid IN (' . implode(',', $ids) . ')';

With numpy 1.3 or svn you can do this

In [1]: a = arange(10000.).reshape(100,100)

In [3]: isnan(a.max())
Out[3]: False

In [4]: a[50,50] = nan

In [5]: isnan(a.max())
Out[5]: True

In [6]: timeit isnan(a.max())
10000 loops, best of 3: 66.3 µs per loop

The treatment of nans in comparisons was not consistent in earlier versions.

You need to put your main code on the OnStart method.

This other SO answer of mine might help.

You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.

EDIT:

Please see also the documentation available here for the OnStart method at the MSDN where one can read this:

Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.

For those using hooks, the following code will work.

React.useEffect(() => {
  window.scrollTo(0, 0);
}, []);

Note, you can also import useEffect directly: import { useEffect } from 'react'

Within Excel you need to set a reference to the VB script run-time library. The relevant file is usually located at \Windows\System32\scrrun.dll

• To reference this file, load the Visual Basic Editor (ALT+F11)
• Select Tools > References from the drop-down menu
• A listbox of available references will be displayed
• Tick the check-box next to 'Microsoft Scripting Runtime'
• The full name and path of the scrrun.dll file will be displayed below the listbox
• Click on the OK button.

This can also be done directly in the code if access to the VBA object model has been enabled.

Access can be enabled by ticking the check-box Trust access to the VBA project object model found at File > Options > Trust Center > Trust Center Settings > Macro Settings

To add a reference:

Sub Add_Reference()

    Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\System32\scrrun.dll"
'Add a reference

End Sub

To remove a reference:

Sub Remove_Reference()

Dim oReference As Object

    Set oReference = Application.VBE.ActiveVBProject.References.Item("Scripting")

    Application.VBE.ActiveVBProject.References.Remove oReference
'Remove a reference

End Sub

There are a couple of important things to know about bash's [[ ]] construction. The first:

Word splitting and pathname expansion are not performed on the words between the [[ and ]]; tilde expansion, parameter and variable expansion, arithmetic expansion, command substitution, process substitution, and quote removal are performed.

The second thing:

An additional binary operator, ‘=~’, is available,... the string to the right of the operator is considered an extended regular expression and matched accordingly... Any part of the pattern may be quoted to force it to be matched as a string.

Consequently, $v on either side of the =~ will be expanded to the value of that variable, but the result will not be word-split or pathname-expanded. In other words, it's perfectly safe to leave variable expansions unquoted on the left-hand side, but you need to know that variable expansions will happen on the right-hand side.

So if you write: [[ $x =~ [$0-9a-zA-Z] ]], the $0 inside the regex on the right will be expanded before the regex is interpreted, which will probably cause the regex to fail to compile (unless the expansion of $0 ends with a digit or punctuation symbol whose ascii value is less than a digit). If you quote the right-hand side like-so [[ $x =~ "[$0-9a-zA-Z]" ]], then the right-hand side will be treated as an ordinary string, not a regex (and $0 will still be expanded). What you really want in this case is [[ $x =~ [\$0-9a-zA-Z] ]]

Similarly, the expression between the [[ and ]] is split into words before the regex is interpreted. So spaces in the regex need to be escaped or quoted. If you wanted to match letters, digits or spaces you could use: [[ $x =~ [0-9a-zA-Z\ ] ]]. Other characters similarly need to be escaped, like #, which would start a comment if not quoted. Of course, you can put the pattern into a variable:

pat="[0-9a-zA-Z ]"
if [[ $x =~ $pat ]]; then ...

For regexes which contain lots of characters which would need to be escaped or quoted to pass through bash's lexer, many people prefer this style. But beware: In this case, you cannot quote the variable expansion:

# This doesn't work:
if [[ $x =~ "$pat" ]]; then ...

Finally, I think what you are trying to do is to verify that the variable only contains valid characters. The easiest way to do this check is to make sure that it does not contain an invalid character. In other words, an expression like this:

valid='0-9a-zA-Z $%&#' # add almost whatever else you want to allow to the list
if [[ ! $x =~ [^$valid] ]]; then ...

! negates the test, turning it into a "does not match" operator, and a [^...] regex character class means "any character other than ...".

The combination of parameter expansion and regex operators can make bash regular expression syntax "almost readable", but there are still some gotchas. (Aren't there always?) One is that you could not put ] into $valid, even if $valid were quoted, except at the very beginning. (That's a Posix regex rule: if you want to include ] in a character class, it needs to go at the beginning. - can go at the beginning or the end, so if you need both ] and -, you need to start with ] and end with -, leading to the regex "I know what I'm doing" emoticon: [][-])

For the lazy and the learning, to put it into your theme, Rfvgyhn's full code

It's a three step process really after installing SQL Server:

1. Enable Named Pipes SQL Config Manager --> SQL Server Network Consif --> Protocols --> Named Pipes --> Right-click --> Restart

2. Restart the server SQL Config Manager --> SQL Server Services --> SQL Server (SQLEXPRESS) --> Right-click --> Restart

3. Use proper server and instance names (both are needed!) Typically this would be .\SQLEXPRESS, for example see the screenshot from QueryExpress connection dialog.

There you have it.

If the concern is the extra compilation time and binary size bloat produced by compiling the .h as part of all the .cpp modules using it, in many cases what you can do is make the template class descend from a non-templatized base class for non type-dependent parts of the interface, and that base class can have its implementation in the .cpp file.

Couldn't you just have your class expose a Dictionary object? Instead of "attaching more properties to the object", you could simply insert your data (with some identifier) into the dictionary at run time.

Before changing the web.config file, I would check that the .NET Framework version that you are using is exactly (I mean it, 4.5 != 4.5.2) the same compared to your GoDaddy settings (ASP.Net settings in your Plesk panel). That should automatically change your web.config file to the correct framework.

Also notice that for now (January '16), GoDaddy works with ASP.Net 3.5 and 4.5.2. To use 4.5.2 with Visual Studio it has to be 2012 or newer, and if not 2015, you must download and install the .NET Framework 4.5.2 Developer Package.

If still not working, then yes, your next step should be enabling detailed error reporting so you can debug it.

if(!file3.exists()){
    file3.createNewFile();
}
FileOutputStream fop=new FileOutputStream(file3,true);
if(nodeValue!=null) fop.write(nodeValue.getBytes());

fop.write("\n".getBytes());

fop.flush();
fop.close();

You need to add a newline at the end of each write.

Alternatively, if you want to simply set the number of ticks while allowing matplotlib to position them (currently only with MaxNLocator), there is pyplot.locator_params,

pyplot.locator_params(nbins=4)

You can specify specific axis in this method as mentioned below, default is both:

# To specify the number of ticks on both or any single axes
pyplot.locator_params(axis='y', nbins=6)
pyplot.locator_params(axis='x', nbins=10)

Array initializer support for type inference were changed in Visual Basic 10 vs Visual Basic 9.

In previous version of VB it was required to put empty parens to signify an array. Also, it would define the array as object array unless otherwise was stated:

' Integer array
Dim i as Integer() = {1, 2, 3, 4} 

' Object array
Dim o() = {1, 2, 3}

You probably do not need to be making lists and appending them to make your array. You can likely just do it all at once, which is faster since you can use numpy to do your loops instead of doing them yourself in pure python.

To answer your question, as others have said, you cannot access a nested list with two indices like you did. You can if you convert mean_data to an array before not after you try to slice it:

R = np.array(mean_data)[:,0]

instead of

R = np.array(mean_data[:,0])

But, assuming mean_data has a shape nx3, instead of

R = np.array(mean_data)[:,0]
P = np.array(mean_data)[:,1]
Z = np.array(mean_data)[:,2]

You can simply do

A = np.array(mean_data).mean(axis=0)

which averages over the 0th axis and returns a length-n array

But to my original point, I will make up some data to try to illustrate how you can do this without building any lists one item at a time:

Check this

UPDATE some_table SET some_field = REPLACE("Column Name/String", 'Search String', 'Replace String')

Eg with sample string:

UPDATE some_table SET some_field = REPLACE("this is test string", 'test', 'sample')

EG with Column/Field Name:

UPDATE some_table SET some_field = REPLACE(columnName, 'test', 'sample')

If you look inside Math.abs you can probably find the best answer:

Eg, for floats:

    /*
     * Returns the absolute value of a {@code float} value.
     * If the argument is not negative, the argument is returned.
     * If the argument is negative, the negation of the argument is returned.
     * Special cases:
     * <ul><li>If the argument is positive zero or negative zero, the
     * result is positive zero.
     * <li>If the argument is infinite, the result is positive infinity.
     * <li>If the argument is NaN, the result is NaN.</ul>
     * In other words, the result is the same as the value of the expression:
     * <p>{@code Float.intBitsToFloat(0x7fffffff & Float.floatToIntBits(a))}
     *
     * @param   a   the argument whose absolute value is to be determined
     * @return  the absolute value of the argument.
     */
    public static float abs(float a) {
        return (a <= 0.0F) ? 0.0F - a : a;
    }

As @Egon mentioned above, there is no real folder management in BLOB storage.

You can achieve some features of a file system using '/' in the file name, but this has many limitations (for example, what happen if you need to rename a "folder"?).

As a general rule, I would keep my files as flat as possible in a container, and have my application manage whatever structure I want to expose to the end users (for example manage a nested folder structure in my database, have a record for each file, referencing the BLOB using container-name and file-name).

The syntax of a programming language is the form of its expressions, statements, and program units. Its semantics is the meaning of those expressions, statements, and program units. For example, the syntax of a Java while statement is

while (boolean_expr) statement

The semantics of this statement form is that when the current value of the Boolean expression is true, the embedded statement is executed. Then control implicitly returns to the Boolean expression to repeat the process. If the Boolean expression is false, control transfers to the statement following the while construct.

The only thing you can do is to upload the image to a server and check the image size and dimension using some server side language like C#.

Edit:

Your need can't be done using javascript only.

Contrary to @Andre Luus, setting Height="Auto" will not make the TextBox stretch. The solution I found was to set VerticalAlignment="Stretch"

AFAIK you can't do that.
What I did at my place of work, is transfer the files to your home (~) folder (or really any folder that you have full permissions in, i.e chmod 777 or variants) via WinSCP, and then SSH to to your linux machine and sudo from there to your destination folder.

Another solution would be to change permissions of the directories you are planning on uploading the files to, so your user (which is without sudo privileges) could write to those dirs.

I would also read about WinSCP Remote Commands for further detail.

I use numpy.size() to do the same:

import numpy as np
import cv2

image = cv2.imread('image.jpg')
height = np.size(image, 0)
width = np.size(image, 1)

Any Reference to 'Row' should use 'long' not 'integer' else it will overflow if the spreadsheet has a lot of data.

nchar requires more space than nvarchar.

eg,

A nchar(100) will always store 100 characters even if you only enter 5, the remaining 95 chars will be padded with spaces. Storing 5 characters in a nvarchar(100) will save 5 characters.

First of all, try to support open source developers when you can, they invest quite a lot of their (free) time into these packages. But if you want to get rid of funding messages, you can configure NPM to turn these off. The command to do this is:

npm config set fund false --global

... or if you just want to turn it off for a particular project, run this in the project directory:

npm config set fund false 

For details why this was implemented, see @Stokely's and @ArunPratap's answers.

comboBox1.SelectedItem = MyEnum.Something;

should work just fine ... How can you tell that SelectedItem is null?

""" Using Flask Class-base View """

from flask import Flask, request, jsonify

from flask.views import MethodView

app = Flask(**__name__**)

app.add_url_rule('/summary/', view_func=Summary.as_view('summary'))

class Summary(MethodView):

    def __init__(self):
        self.response = dict()

    def get(self):
        self.response['summary'] = make_summary()  # make_summary is a method to calculate the summary.
        return jsonify(self.response)

You have to set the Authorization field in the header.

It contains the authentication type Basic in this case and the username:password combination which gets encoded in Base64:

var username = 'Test';
var password = '123';
var auth = 'Basic ' + Buffer.from(username + ':' + password).toString('base64');
// new Buffer() is deprecated from v6

// auth is: 'Basic VGVzdDoxMjM='

var header = {'Host': 'www.example.com', 'Authorization': auth};
var request = client.request('GET', '/', header);

$string="1,2,3,4,5";
$array=array_map('intval', explode(',', $string));
$array = implode("','",$array);
$query=mysqli_query($conn, "SELECT name FROM users WHERE id IN ('".$array."')");

NB: the syntax is:

SELECT * FROM table WHERE column IN('value1','value2','value3')

If you don't need a plot per say, and you're simply interested in adding color to represent the values in a table format, you can use the style.background_gradient() method of the pandas data frame. This method colorizes the HTML table that is displayed when viewing pandas data frames in e.g. the JupyterLab Notebook and the result is similar to using "conditional formatting" in spreadsheet software:

import numpy as np 
import pandas as pd


index= ['aaa', 'bbb', 'ccc', 'ddd', 'eee']
cols = ['A', 'B', 'C', 'D']
df = pd.DataFrame(abs(np.random.randn(5, 4)), index=index, columns=cols)
df.style.background_gradient(cmap='Blues')

For detailed usage, please see the more elaborate answer I provided on the same topic previously and the styling section of the pandas documentation.

By HTML specifications, browsers are required to canonicalize line breaks in user input to CR LF (\r\n), and I don’t think any browser gets this wrong. Reference: clause 17.13.4 Form content types in the HTML 4.01 spec.

In HTML5 drafts, the situation is more complicated, since they also deal with the processes inside a browser, not just the data that gets sent to a server-side form handler when the form is submitted. According to them (and browser practice), the textarea element value exists in three variants:

1. the raw value as entered by the user, unnormalized; it may contain CR, LF, or CR LF pair;
2. the internal value, called “API value”, where line breaks are normalized to LF (only);
3. the submission value, where line breaks are normalized to CR LF pairs, as per Internet conventions.

I am using Select2 4.0. This works for me. I only have one Select2 control.

.select2-selection.select2-selection--multiple {
    min-height: 25px;
    max-height: 25px;
}

Set Clickable as false and change the backgroung color as:

callButton.setClickable(false);
callButton.setBackgroundColor(Color.parseColor("#808080"));

If you want one line:

list_of_dict = [{} for i in range(list_len)]

You simply misspelled $stateParam, it should be $stateParams (with an s). That's why you get undefined ;)

If you want to see output logs from all the services in your terminal.

docker-compose logs -t -f --tail <no of lines> 

Eg.: Say you would like to log output of last 5 lines from all service

docker-compose logs -t -f --tail 5

If you wish to log output from specific services then it can be done as below:

docker-compose logs -t -f --tail <no of lines> <name-of-service1> <name-of-service2> ... <name-of-service N>

Usage:

Eg. say you have API and portal services then you can do something like below :

docker-compose logs -t -f --tail 5 portal api

Where 5 represents last 5 lines from both logs.

Ref: https://docs.docker.com/v17.09/engine/admin/logging/view_container_logs/

This feels very hacky, but in chrome 41 on ubuntu I can make a <br> slightly stylable:

br {
  content: "";
  margin: 2em;
  display: block;
  font-size: 24%;
}

I control the spacing with the font size.

Update

I made some test cases to see how the response changes as browsers update.

*{outline: 1px solid hotpink;}
div {
  display: inline-block;
  width: 10rem;
  margin-top: 0;
  vertical-align: top;
}

h2 {
  display: block;
  height: 3rem;
  margin-top:0;
}

.old br {
  content: "";
  margin: 2em;
  display: block;
  font-size: 24%;
  outline: red;
}

.just-font br {
  content: "";
  display: block;
  font-size: 200%;
}
.just-margin br {
  content: "";
  display: block;
  margin: 2em;
}

.brbr br {
  content: "";
  display: block;
  font-size: 100%;
  height: 1em;
  outline: red;
  display: block;
}

<div class="raw">
  <h2>Raw <code>br</code>rrrrs</h2>
  bla<BR><BR>bla<BR>bla<BR><BR>bla
</div>
  
<div class="old">
  <h2>margin & font size</h2>
  bla<BR><BR>bla<BR>bla<BR><BR>bla
</div>
  
<div class="just-font">
  <h2>only font size</h2>
  bla<BR><BR>bla<BR>bla<BR><BR>bla
</div>

 <div class="just-margin">
  <h2>only margin</h2>
  bla<BR><BR>bla<BR>bla<BR><BR>bla
</div>
   
<div class="brbr">
  <h2><code>br</code>others vs only <code>br</code>s</h2>
  bla<BR><BR>bla<BR>bla<BR><BR>bla
</div>

They all have their own version of strange behaviour. Other than the browser default, only the last one respects the difference between one and two brs.

I prefer this one, I have tested it and its working

To make more than one element fade in/out sequentially such as 5 elements fade each 4s,

1- make unique animation for each element with animation-duration equal to [ 4s (duration for each element) * 5 (number of elements) ] = 20s

animation-name: anim1 , anim2, anim3 ... 
animation-duration : 20s, 20s, 20s ... 

2- get animation keyframe for each element.

100% (keyframes percentage) / 5 (elements) = 20% (frame for each element)

3- define starting and ending point for each animation:

each animation has 20% frame length and @keyframes percentage always starts from 0%, so first animation will start from 0% and end in his frame(20%), and each next animation will starts from previous animation ending point and end when it reach his frame (+20% ),

@keyframes animation1 { 0% {}, 20% {}}
@keyframes animation2 { 20% {}, 40% {}}
@keyframes animation3 { 40% {}, 60% {}}
and so on

now we need to make each animation fade in from 0 to 1 opacity and fade out from 1 to 0,

so we will add another 2 points (steps) for each animation after starting and before ending point to handle the full opacity(1)

The other answers on here are great and answer your question, but this is the top google result for "bash get list of files in directory", (which I was looking for to save a list of files) so I thought I would post an answer to that problem:

ls $search_path > filename.txt

If you want only a certain type (e.g. any .txt files):

ls $search_path | grep *.txt > filename.txt

Note that $search_path is optional; ls > filename.txt will do the current directory.

getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.drawable.ic_launcher);

OR make a XML layout call the tool_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@color/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:elevation="4dp">

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:src="@drawable/ic_action_search"/>

    </RelativeLayout>
</android.support.v7.widget.Toolbar>

Now in you main activity add this line

 <include
     android:id="@+id/tool_bar"
     layout="@layout/tool_bar" />

Replace double quotes with single ones:

INSERT
INTO    MY.LOGFILE
        (id,severity,category,logdate,appendername,message,extrainfo)
VALUES  (
       'dee205e29ec34',
       'FATAL',
       'facade.uploader.model',
       '2013-06-11 17:16:31',
       'LOGDB',
       NULL,
       NULL
       )

In SQL, double quotes are used to mark identifiers, not string constants.

The very first time you import goo from anywhere (inside or outside a function), goo.py (or other importable form) is loaded and sys.modules['goo'] is set to the module object thus built. Any future import within the same run of the program (again, whether inside or outside a function) just look up sys.modules['goo'] and bind it to barename goo in the appropriate scope. The dict lookup and name binding are very fast operations.

Assuming the very first import gets totally amortized over the program's run anyway, having the "appropriate scope" be module-level means each use of goo.this, goo.that, etc, is two dict lookups -- one for goo and one for the attribute name. Having it be "function level" pays one extra local-variable setting per run of the function (even faster than the dictionary lookup part!) but saves one dict lookup (exchanging it for a local-variable lookup, blazingly fast) for each goo.this (etc) access, basically halving the time such lookups take.

We're talking about a few nanoseconds one way or another, so it's hardly a worthwhile optimization. The one potentially substantial advantage of having the import within a function is when that function may well not be needed at all in a given run of the program, e.g., that function deals with errors, anomalies, and rare situations in general; if that's the case, any run that does not need the functionality will not even perform the import (and that's a saving of microseconds, not just nanoseconds), only runs that do need the functionality will pay the (modest but measurable) price.

It's still an optimization that's only worthwhile in pretty extreme situations, and there are many others I would consider before trying to squeeze out microseconds in this way.

You do realize that format has nothing to do with how SQL Server stores datetime, right?

You can use set dateformat for each session. There is no setting for database only.

If you use parameters for data insert or update or where filtering you won't have any problems with that.

you can loop through the data frame like this .

for ad in range(1,dataframe_c.size):
    print(dataframe_c.values[ad])

For new Xcode 11.xxx and Swift 5.xx, where the target it set to iOS 13+.

For the new project structure, AppDelegate does not have to do anything regarding rootViewController.

A new class is there to handle window(UIWindowScene) class -> 'SceneDelegate' file.

class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

    if let windowScene = scene as? UIWindowScene {
        let window = UIWindow(windowScene: windowScene)
        window.rootViewController = // Your RootViewController in here
        self.window = window
        window.makeKeyAndVisible()
    }

}

The documentation for Gerrit, in particular the "Push changes" section, explains that you push to the "magical refs/for/'branch' ref using any Git client tool".

The following image is taken from the Intro to Gerrit. When you push to Gerrit, you do git push gerrit HEAD:refs/for/<BRANCH>. This pushes your changes to the staging area (in the diagram, "Pending Changes"). Gerrit doesn't actually have a branch called <BRANCH>; it lies to the git client.

Internally, Gerrit has its own implementation for the Git and SSH stacks. This allows it to provide the "magical" refs/for/<BRANCH> refs.

When a push request is received to create a ref in one of these namespaces Gerrit performs its own logic to update the database, and then lies to the client about the result of the operation. A successful result causes the client to believe that Gerrit has created the ref, but in reality Gerrit hasn’t created the ref at all. [Link - Gerrit, "Gritty Details"].

After a successful patch (i.e, the patch has been pushed to Gerrit, [putting it into the "Pending Changes" staging area], reviewed, and the review has passed), Gerrit pushes the change from the "Pending Changes" into the "Authoritative Repository", calculating which branch to push it into based on the magic it did when you pushed to refs/for/<BRANCH>. This way, successfully reviewed patches can be pulled directly from the correct branches of the Authoritative Repository.

Usually I use the === (triple equals) and __LINE__ , __CLASS__ to locate the error in my code:

$query=mysql_query('SELECT champ FROM table')
or die("SQL Error line  ".__LINE__ ." class ".__CLASS__." : ".mysql_error());

mysql_close();

if(mysql_num_rows($query)===0)
{
    PERFORM ACTION;
}
else
{
    while($r=mysql_fetch_row($query))
    {
          PERFORM ACTION;
    }
}

See the timeseries documentation. It includes a list of offsets (and 'anchored' offsets), and a section about resampling.

Note that there isn't a list of all the different how options, because it can be any NumPy array function and any function that is available via groupby dispatching can be passed to how by name.

Please follow the below steps, it should work.

1 - Uninstall current installation completely

Source - official instructions

sudo service mongod stop

Remove Packages

sudo apt-get purge mongodb-org*

Remove the folders

sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb

2 - Reinstall as described on official site, I will just write down the all steps. enter link description here

Import the public key

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

Create a list file for Ubuntu 16.04

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list

update the list

sudo apt-get update

Install the latest package

sudo apt-get install -y mongodb-org

3 - Now it should work, please try below command

sudo service mongod start

and check the status

mongo

it should appear the mongo shell

Try jQuery.map function, works pretty well with maps.

var mapArray = {_x000D_
  "lastName": "Last Name cannot be null!",_x000D_
  "email": "Email cannot be null!",_x000D_
  "firstName": "First Name cannot be null!"_x000D_
};_x000D_
_x000D_
$.map(mapArray, function(val, key) {_x000D_
  alert("Value is :" + val);_x000D_
  alert("key is :" + key);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

You can use js fetch

async function send(url,data) {_x000D_
  let r= await fetch(url, {_x000D_
        method: "POST", _x000D_
        headers: {_x000D_
          "My-header": "abc"  _x000D_
        },_x000D_
        body: JSON.stringify(data), _x000D_
  })_x000D_
  return await r.json()_x000D_
}_x000D_
_x000D_
// Example usage_x000D_
_x000D_
let url='https://server.test-cors.org/server?enable=true&status=200&methods=POST&headers=my-header';_x000D_
_x000D_
async function run() _x000D_
{_x000D_
 let jsonObj = await send(url,{ some: 'testdata' });_x000D_
 console.log(jsonObj[0].request.httpMethod + ' was send - open chrome console > network to see it');_x000D_
}_x000D_
_x000D_
run();

In the end, you only have two options:

You generate your content using Doxygen, or you generate your content using Sphinx*.

1. Doxygen: It is not the tool of choice for most Python projects. But if you have to deal with other related projects written in C or C++ it could make sense. For this you can improve the integration between Doxygen and Python using doxypypy.

2. Sphinx: The defacto tool for documenting a Python project. You have three options here: manual, semi-automatic (stub generation) and fully automatic (Doxygen like).

   1. For manual API documentation you have Sphinx autodoc. This is great to write a user guide with embedded API generated elements.
   2. For semi-automatic you have Sphinx autosummary. You can either setup your build system to call sphinx-autogen or setup your Sphinx with the autosummary_generate config. You will require to setup a page with the autosummaries, and then manually edit the pages. You have options, but my experience with this approach is that it requires way too much configuration, and at the end even after creating new templates, I found bugs and the impossibility to determine exactly what was exposed as public API and what not. My opinion is this tool is good for stub generation that will require manual editing, and nothing more. Is like a shortcut to end up in manual.
   3. Fully automatic. This have been criticized many times and for long we didn't have a good fully automatic Python API generator integrated with Sphinx until AutoAPI came, which is a new kid in the block. This is by far the best for automatic API generation in Python (note: shameless self-promotion).

There are other options to note:

• Breathe: this started as a very good idea, and makes sense when you work with several related project in other languages that use Doxygen. The idea is to use Doxygen XML output and feed it to Sphinx to generate your API. So, you can keep all the goodness of Doxygen and unify the documentation system in Sphinx. Awesome in theory. Now, in practice, the last time I checked the project wasn't ready for production.
• pydoctor*: Very particular. Generates its own output. It has some basic integration with Sphinx, and some nice features.

git push origin master

Synchronized normal method equivalent to Synchronized statement (use this)

class A {
    public synchronized void methodA() {
        // all function code
    }

    equivalent to

    public void methodA() {
        synchronized(this) {
             // all function code
        }
    } 
}

Synchronized static method equivalent to Synchronized statement (use class)

class A {
    public static synchronized void methodA() {
        // all function code
    }

    equivalent to

    public void methodA() {
        synchronized(A.class) {
             // all function code
        }
    } 
}

Synchronized statement (using variable)

class A {
    private Object lock1 = new Object();

    public void methodA() {
        synchronized(lock1 ) {
             // all function code
        }
    } 
}

For synchronized, we have both Synchronized Methods and Synchronized Statements. However, Synchronized Methods is similar to Synchronized Statements so we just need to understand Synchronized Statements.

=> Basically, we will have

synchronized(object or class) { // object/class use to provides the intrinsic lock
   // code 
}

Here is 2 think that help understanding synchronized

• Every object/class have an intrinsic lock associated with it.
• When a thread invokes a synchronized statement, it automatically acquires the intrinsic lock for that synchronized statement's object and releases it when the method returns. As long as a thread owns an intrinsic lock, NO other thread can acquire the SAME lock => thread safe.

=> When a thread A invokes synchronized(this){// code 1} => all the block code (inside class) where have synchronized(this) and all synchronized normal method (inside class) is locked because SAME lock. It will execute after thread A unlock ("// code 1" finished).

This behavior is similar to synchronized(a variable){// code 1} or synchronized(class).

SAME LOCK => lock (not depend on which method? or which statements?)

Use synchronized method or synchronized statements?

I prefer synchronized statements because it is more extendable. Example, in future, you only need synchronized a part of method. Example, you have 2 synchronized method and it don't have any relevant to each other, however when a thread run a method, it will block the other method (it can prevent by use synchronized(a variable)).

However, apply synchronized method is simple and the code look simple. For some class, there only 1 synchronized method, or all synchronized methods in the class in relevant to each other => we can use synchronized method to make code shorter and easy to understand

Note

(it not relevant to much to synchronized, it is the different between object and class or none-static and static).

• When you use synchronized or normal method or synchronized(this) or synchronized(non-static variable) it will synchronized base on each object instance.
• When you use synchronized or static method or synchronized(class) or synchronized(static variable) it will synchronized base on class

Easiest:

<a href="page2.php">Link</a>

And if you need to pass a value:

<a href="page2.php?val=1">Link that pass the value 1</a>

To retrive the value put in page2.php this code:

<?php
$val = $_GET["val"];
?>

Now the variable $val has the value 1.

Answering my own question here... turns out it's a Windows only quirk that happens when reading binary files (in my case a JPEG) that requires an additional flag in the open or File.open function call. I revised it to open("/path/to/file", 'rb') {|io| a = a + io.read} and all was fine.

To get the smallest or largest item in a list, use the built-in min and max functions:

 lo = min(L)
 hi = max(L)  

As with sort, you can pass in a "key" argument that is used to map the list items before they are compared:

 lo = min(L, key=int)
 hi = max(L, key=int)

http://effbot.org/zone/python-list.htm

Looks like you could use the max function if you map it correctly for strings and use that as the comparison. I would recommend just finding the max once though of course, not for each element in the list.

You can achieve what you want by defining a footer for the tableview. See this answer for more details:Eliminate Extra separators below UITableView

hope this is working. make random number between range for arc4random_uniform()?

var randomNumber = Int(arc4random_uniform(6))
print(randomNumber)

Be careful if you have spaces in your string variables and you check for existence. Be sure to quote them properly.

if [ ! "${somepath}" ] || [ ! "${otherstring}" ] || [ ! "${barstring}" ] ; then

The answers provided by other folks (Ben James) are quite good and I have used them. As user889030 points out, the last array element may be empty. Actually, the first and last array elements can be empty. The code below addresses both issues.

# Split an input string into an array of substrings using any set
# whitespace characters
function explode_whitespace($str) {  
  # Split the input string into an array
  $parts = preg_split('/\s+/', $str);
  # Get the size of the array of substrings
  $sizeParts = sizeof($parts);
  # Check if the last element of the array is a zero-length string
  if ($sizeParts > 0) {
    $lastPart = $parts[$sizeParts-1];
    if ($lastPart == '') {
      array_pop($parts);
      $sizeParts--;
    }
    # Check if the first element of the array is a zero-length string
    if ($sizeParts > 0) {
      $firstPart = $parts[0];
      if ($firstPart == '') 
        array_shift($parts); 
    }
  }
  return $parts;   
}

There are pretty limited scenarios that I can think of where this would be useful, but let's assume you can't get funds to purchase VS2012 or something to that effect. If that's the case and you have Windows 7+ and VS 2010 you may be able to use the following hack I put together which seems to work (but I haven't fully deployed an application using this method yet).

1. Backup your project file!!!

2. Download and install the Windows 8 SDK which includes the .NET 4.5 SDK.

3. Open your project in VS2010.

4. Create a text file in your project named Compile_4_5_CSharp.targets with the following contents. (Or just download it here - Make sure to remove the ".txt" extension from the file name):

   <Project DefaultTargets="Build"
    xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
   
       <!-- Change the target framework to 4.5 if using the ".NET 4.5" configuration -->
       <PropertyGroup Condition=" '$(Platform)' == '.NET 4.5' ">
           <DefineConstants Condition="'$(DefineConstants)'==''">
               TARGETTING_FX_4_5
           </DefineConstants>
           <DefineConstants Condition="'$(DefineConstants)'!='' and '$(DefineConstants)'!='TARGETTING_FX_4_5'">
               $(DefineConstants);TARGETTING_FX_4_5
           </DefineConstants>
           <PlatformTarget Condition="'$(PlatformTarget)'!=''"/>
           <TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
       </PropertyGroup>
   
       <!-- Import the standard C# targets -->
       <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
   
       <!-- Add .NET 4.5 as an available platform -->
       <PropertyGroup>
          <AvailablePlatforms>$(AvailablePlatforms),.NET 4.5</AvailablePlatforms>
       </PropertyGroup>
   </Project>
   

5. Unload your project (right click -> unload).

6. Edit the project file (right click -> Edit *.csproj).

7. Make the following changes in the project file:

   a. Replace the default Microsoft.CSharp.targets with the target file created in step 4

   <!-- Old Import Entry -->
   <!-- <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" /> -->
   
   <!-- New Import Entry -->
   <Import Project="Compile_4_5_CSharp.targets" />
   

   b. Change the default platform to .NET 4.5

   <!-- Old default platform entry -->
   <!-- <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform> -->
   
   <!-- New default platform entry -->
   <Platform Condition=" '$(Platform)' == '' ">.NET 4.5</Platform>
   

   c. Add AnyCPU platform to allow targeting other frameworks as specified in the project properties. This should be added just before the first <ItemGroup> tag in the file

   <PropertyGroup Condition="'$(Platform)' == 'AnyCPU'">
       <PlatformTarget>AnyCPU</PlatformTarget>
   </PropertyGroup>
   
   .
   .
   .
   <ItemGroup>
   .
   .
   .
   

8. Save your changes and close the *.csproj file.

9. Reload your project (right click -> Reload Project).

10. In the configuration manager (Build -> Configuration Manager) make sure the ".NET 4.5" platform is selected for your project.

11. Still in the configuration manager, create a new solution platform for ".NET 4.5" (you can base it off "Any CPU") and make sure ".NET 4.5" is selected for the solution.

12. Build your project and check for errors.

13. Assuming the build completed you can verify that you are indeed targeting 4.5 by adding a reference to a 4.5 specific class to your source code:

    using System;
    using System.Text;
    
    namespace testing
    {
        using net45check = System.Reflection.ReflectionContext;
    }
    

14. When you compile using the ".NET 4.5" platform the build should succeed. When you compile under the "Any CPU" platform you should get a compiler error:

    Error 6: The type or namespace name 'ReflectionContext' does not exist in
    the namespace 'System.Reflection' (are you missing an assembly reference?)
    

Replace any special characters by

replaceAll("\\your special character","new character");

ex:to replace all the occurrence of * with white space

replaceAll("\\*","");

*this statement can only replace one type of special character at a time

Two typical problems:

1. Missing the ProjectInstaller class (as @MiguelAngelo has pointed)
2. The command prompt must “Run as Administrator”

Java based workflow engines like Activiti, Bonita or jBPM support a wide range of the BPMN 2.0 specification. Therefore, you can model processes in a graphical way. In addition, some of those engines have simulation capabilities like Activiti (with Activiti Crystalball). If you code the processes on your own, you aren´t as flexible when you need to change the process. Therefore, I would also advice to use a java based BPM engine.

I did a research concerning BPMN 2.0 based Open Source Engines. Here are the key-points which were relevant for our concrete use case:

1. Bonita:

Bonita has a zero-coding approach which means that they provide an easy to use IDE to build your processes without the need for coding. To achieve that, Bonita has the concept of connectors. For example, if you want to consume a web service, they provide you with a graphical wizzard. The downside is that you have to write the plain XML SOAP-envelope manually and copy it in a graphical textbox. The problem with this approach is that you only can realize use cases which are intended by Bonita. If you want to integrate a system which Bonita did not developed a connector for, you have to code such a connector on your own which is very painful. For example, Bonita offers a SOAP connector for consuming SOAP web services. This connector only works with SOAP 1.2, but not for SOAP 1.1 (http://community.bonitasoft.com/answers/consume-soap-11-webservices-bonita-secure-web-service-connector). If you have a legacy application with SOAP 1.1, you cannot integrate this system easily in your process. The same is true for databases. There are only a few database connectors for dedicated database versions. If you have a version not matching to a connector, you have to code this on your own.

In addition, Bonita has no support for LDAP or Active Directory Sync in the free community edition which is quite a showstopper for a production environment. Another thing to consider is that Bonita is licensed under the GPL / LGPL license which could cause problems when you want to integrate Bonita in another enterprise application. In addition, the community support is very weak. There are several posts which are more than 2 years old and those posts are still not answered.

Another important thing is Business-IT-Alignment. Modelling processes is a collaborative discipline in which IT AND the business analysts are involed. That is why you need adequate tools for both user groups (e.g. an Eclipse Plugin for the developers and an easy to use web modeler for the business people). Bonita only offers Bonita Studio, which needs to be installed on your machine. This IDE is quite technical and not suitable for business users. Therefore, it is very hard to realize Business-IT-Alignment with Bonita.

Bonita is a BPM tool for very trivial and easy processes. Because of the zero-coding approach, the lerning curve is very low and you can start modelling very fast. You need less programming skills and you are able to realize your processes without the need of coding. But as soon as your processes become very complex, Bonita might not be the best solution because of the lack of flexibility. You only can realize use cases which are intended by Bonita.

2. jBPM:

jBPM is a very powerful Open Source BPM Engine which has a lot of features. The web modeler even supports prefabricated models of some van der Aalst workflow patterns (workflowpatterns.com). Business-IT-Alignment is realizable because jBPM offers an Eclipse integration as well as a web-based modeler. A bit tricky is that you only can define forms in the web modeler, but not in the Eclipse Plugin, as far as I know. To sum up, jBPM is a good candidate for using in a company. Our showstopper was the scalability. jBPM is based on the Rules-Engine Drools. This leads to the fact that whole process instances are persisted as BLOBS in the database. This is a critial showstopper when you consider searching and scalability.

In addition, the learning curve is very high because of the complexity. jBPM does not offer a Service Task like the BPMN-Standard suggests In contrast, you have to define your own Java Service tasks and you have to register them manually in the engine, which results in quite low level programming.

3. Activiti:

In the end, we went with Activiti because this is a very easy to use framework-based engine. It offers an Eclipse Plugin as well as a modern AngularJS Web-Modeler. In this way, you can realize Business-IT-Alignment. The REST-API is secured by Spring Security which means that you can extend the Engine very easily with Single Sign-on features. Because of the Apache License 2.0, there is no copyleft which means you are completely free in terms of usage and extensibility which is very important in a productive environment.

In addition, the BPMN-coverage is very good. Not all BPMN-elements are realized, but I do not know any engine which does that.

The Activiti Explorer is a demo frontend which demonstrates the usage of the Activiti APIs. Since this frontend is based on VAADIN, it can be extended very easily. The community is very active which means that you can get help very fast if you have any problems.

Activiti offers good integration points for external form-technologies which is very important for a productive usage. The form-technologies of all candidates are very restrictive. Therefore, it makes sense to use a standard form-technology like XForms in combination with the Engine. Even such more complex things are realizable via the formKey-Attribute.

Activiti does not follow the zero-coding approach which means that you will need a bit of coding if you want to orchestrate services. But even the communication with SOAP services can be achieved by using a Java Service Task and Apache CXF. The coding effort is low.

I hope that my key points can help by taking a decision. To be clear, this is no advertisment for Activiti. The right product choice depends on the concrete use cases. I only want to point out the most important points in our project

It means that element with id passed to getElementById() does not exist.

From the man page:

-h, --no-filename
    Suppress the prefixing of file names on output. This is the default when there
    is only one file (or only standard input) to search.

I noticed that postgres 9.2 now calls the column pid rather than procpid.

I tend to call it from the shell:

#!/usr/bin/env bash
# kill all connections to the postgres server
if [ -n "$1" ] ; then
  where="where pg_stat_activity.datname = '$1'"
  echo "killing all connections to database '$1'"
else
  echo "killing all connections to database"
fi

cat <<-EOF | psql -U postgres -d postgres 
SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
${where}
EOF

Hope that is helpful. Thanks to @JustBob for the sql.

Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....

The server may need read permission for your home directory and .htaccess therein

To create an option that needs no value, set the action ^[docs] of it to 'store_const', 'store_true' or 'store_false'.

Example:

parser.add_argument('-s', '--simulate', action='store_true')

1. Run Ripple emulator(retired as of 2015-12-06) on Chrome
2. Run iPadian on WineHQ
3. Run QMole on Linux or Android
4. Run XCode on PureDarwin

Also you can do join:

var qwe = new List<int> {5, 2, 3, 8};
Console.WriteLine(string.Join("\t", qwe));

May be it helps.

You can

SET @somevar := '';
SELECT @somevar AS user_name FROM users WHERE (@somevar := `u_name`) = "john";

It works.

BUT MAKE SURE WHAT YOU DO!

• Indexes are NOT USED here
• There will be scanned FULL TABLE - you hasn't specified the LIMIT 1 part
• So, - THIS QUERY WILL BE SLLLOOOOOOW on huge tables.

But, may be it helps in some cases

To summarise solutions from a couple of questions/answers:

If you want to get the current scroll offset use:

$(document).scrollTop()

To set the scroll offset use:

$('html,body').scrollTop(x)

To animate the scroll use use:

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

1. Open Terminal
2. cd ~/Library/MobileDevice/
3. open ./

Now the finder window will be open with Provisioning Profiles folder. Delete all or any provisioning profiles from here and it will reflect in Xcode.

It depends whether you are talking about data, or the code contained within a spreadsheet. While I have a strong dislike of Microsoft's Visual Sourcesafe and normally would not recommended it, it does integrate easily with both Access and Excel, and provides source control of modules.

[In fact the integration with Access, includes queries, reports and modules as individual objects that can be versioned]

The MSDN link is here.

This is not an answer to the original question "What are the differences between .gitignore and .gitkeep?" but posting here to help people to keep track of empty dir in a simple fashion. To track empty directory and knowling that .gitkeep is not official part of git,

just add a empty (with no content) .gitignore file in it.

So for e.g. if you have /project/content/posts and sometimes posts directory might be empty then create empty file /project/content/posts/.gitignore with no content to track that directory and its future files in git.

after reading this thread, the best i could write is:

static Random random = new Random(System.currentTimeMillis());
public static <T> T randomChoice(T[] choices)
{
    int index = random.nextInt(choices.length);
    return choices[index];
}

You can use the bootstrap grid system. as Yoann said

 <div class="container">
    <div class="row">
        <form role="form">
           <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputEmail1">Email address</label>
                        <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
                    </div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputEmail1">Name</label>
                        <input type="text" class="form-control" id="exampleInputEmail1" placeholder="Enter Name">
                    </div>
                    <div class="clearfix"></div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputPassword1">Password</label>
                        <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
                    </div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputPassword1">Confirm Password</label>
                        <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Confirm Password">
                    </div>
          </form>
         <div class="clearfix">
      </div>
    </div>
</div>

Yes surely you can add one, as already mentioned for initialization of Abstract class variables. BUT if you dont explicitly declare one, it anyways has an implicit constructor for "Constructor Chaining" to work.

You can use on Centos or RHEL for local user:

echo $"export PATH=\$PATH:$(pwd)" >> ~/.bash_profile

This add the current directory(or you can use other directory) to the PATH, this make it permanent but take effect at the next user logon.

If you don't want do a re-logon, then can use:

source ~/.bash_profile

That reload the # User specific environment and startup programs this comment is present in .bash_profile

• Hold as a decimal.
• Add check constraints if you want to limit the range (e.g. between 0 to 100%; in some cases there may be valid reasons to go beyond 100% or potentially even into the negatives).
• Treat value 1 as 100%, 0.5 as 50%, etc. This will allow any math operations to function as expected (i.e. as opposed to using value 100 as 100%).
• Amend precision and scale as required (these are the two values in brackets columnName decimal(precision, scale). Precision says the total number of digits that can be held in the number, scale says how many of those are after the decimal place, so decimal(3,2) is a number which can be represented as #.##; decimal(5,3) would be ##.###.
• decimal and numeric are essentially the same thing. However decimal is ANSI compliant, so always use that unless told otherwise (e.g. by your company's coding standards).

Example Scenarios

• For your case (0.00% to 100.00%) you'd want decimal(5,4).
• For the most common case (0% to 100%) you'd want decimal(3,2).
• In both of the above, the check constraints would be the same

Example:

if object_id('Demo') is null
create table Demo
    (
        Id bigint not null identity(1,1) constraint pk_Demo primary key
        , Name nvarchar(256) not null constraint uk_Demo unique 
        , SomePercentValue decimal(3,2) constraint chk_Demo_SomePercentValue check (SomePercentValue between 0 and 1)
        , SomePrecisionPercentValue decimal(5,2) constraint chk_Demo_SomePrecisionPercentValue check (SomePrecisionPercentValue between 0 and 1)
    )

Further Reading:

• Decimal Scale & Precision: http://msdn.microsoft.com/en-us/library/aa258832%28SQL.80%29.aspx
• 0 to 1 vs 0 to 100: C#: Storing percentages, 50 or 0.50?
• Decimal vs Numeric: Is there any difference between DECIMAL and NUMERIC in SQL Server?

For me the problem was that changing the value for this field didn`t work:

$('#cardNumber').val(maskNumber);

None of the solutions above worked for me so I investigated further and found:

According to DOM Level 2 Event Specification: The change event occurs when a control loses the input focus and its value has been modified since gaining focus. That means that change event is designed to fire on change by user interaction. Programmatic changes do not cause this event to be fired.

The solution was to add the trigger function and cause it to trigger change event like this:

$('#cardNumber').val(maskNumber).trigger('change');

A quick search in google provided this:

 function mysqlTimeStampToDate(timestamp) {
    //function parses mysql datetime string and returns javascript Date object
    //input has to be in this format: 2007-06-05 15:26:02
    var regex=/^([0-9]{2,4})-([0-1][0-9])-([0-3][0-9]) (?:([0-2][0-9]):([0-5][0-9]):([0-5][0-9]))?$/;
    var parts=timestamp.replace(regex,"$1 $2 $3 $4 $5 $6").split(' ');
    return new Date(parts[0],parts[1]-1,parts[2],parts[3],parts[4],parts[5]);
  }

Lots of hate for the Convert class here... Just to balance a little bit, there is one advantage for Convert - if you are handed an object,

Convert.ToDouble(o);

can just return the value easily if o is already a Double (or an int or anything readily castable).

Using Double.Parse or Double.TryParse is great if you already have it in a string, but

Double.Parse(o.ToString());

has to go make the string to be parsed first and depending on your input that could be more expensive.

I use the following code which seems to be working fine:

function _bot_detected() {

  return (
    isset($_SERVER['HTTP_USER_AGENT'])
    && preg_match('/bot|crawl|slurp|spider|mediapartners/i', $_SERVER['HTTP_USER_AGENT'])
  );
}

update 16-06-2017 https://support.google.com/webmasters/answer/1061943?hl=en

added mediapartners

I just spent about 1 hour to figure out possible solution for the same error.

So what I did under MS WIndows 7 is following

1. Uninstall all Java packages of all versions.

2. Download last packages Java SE or JRE for your 32 or 64 Windows and install it.

3. First install JRE and second is Java SE.

4. Open text editor and paste this code.

   public class Hello {

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

5. Save it like Hello.java

6. Go to Console and compile it like

javac Hello.java

7. Execute the code like

java Hello

Should be no error.

The selector would be #demolist.dropdown-menu li a note no space between id and class. However i would suggest a more generic approach:

<div class="input-group">                                            
    <input type="TextBox" Class="form-control datebox"></input>
    <div class="input-group-btn">
    <button type="button" class="btn dropdown-toggle" data-toggle="dropdown">
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
        <li><a href="#">A</a></li>
        <li><a href="#">B</a></li>
        <li><a href="#">C</a></li>
    </ul>
</div>


$(document).on('click', '.dropdown-menu li a', function() {
    $(this).parent().parent().parent().find('.datebox').val($(this).html());
}); 

by using a class rather than id, and using parent().find(), you can have as many of these on a page as you like, with no duplicated js

Try creating a method in your Activity something like...

public void setActivityBackgroundColor(int color) {
    View view = this.getWindow().getDecorView();
    view.setBackgroundColor(color);
}

Then call it from your OnClickListener passing in whatever colour you want.

Singleton is, of course, an "anti-pattern" (assuming a definition of a static with variable state).

If you want a fixed set of immutable value objects, then enums are the way to go. For a large, possibly open-ended set of values, you can use a Repository of some form - usually based on a Map implementation. Of course, when you are dealing with statics be careful with threading (either synchronise sufficiently widely or use a ConcurrentMap either checking that another thread hasn't beaten you or use some form of futures).

if you use recompose, use mapProps to make new props derived from incoming props

Edit for example:

import { compose, mapProps } from 'recompose';

const SomeComponent = ({ url, onComplete }) => (
  {url ? (
    <View />
  ) : null}
)

export default compose(
  mapProps(({ url, storeUrl, history, ...props }) => ({
    ...props,
    onClose: () => {
      history.goBack();
    },
    url: url || storeUrl,
  })),
)(SomeComponent);

I solved this issue by accessing my fragments directly through the FragmentManager instead of via the FragmentPagerAdapter like so. First I need to figure out the tag of the fragment auto generated by the FragmentPagerAdapter...

private String getFragmentTag(int pos){
    return "android:switcher:"+R.id.viewpager+":"+pos;
}

Then I simply get a reference to that fragment and do what I need like so...

Fragment f = this.getSupportFragmentManager().findFragmentByTag(getFragmentTag(1));
((MyFragmentInterface) f).update(id, name);
viewPager.setCurrentItem(1, true);

Inside my fragments I set the setRetainInstance(false); so that I can manually add values to the savedInstanceState bundle.

@Override
public void onSaveInstanceState(Bundle outState) {
    if(this.my !=null)
        outState.putInt("myId", this.my.getId());

    super.onSaveInstanceState(outState);
}

and then in the OnCreate i grab that key and restore the state of the fragment as necessary. An easy solution which was hard (for me at least) to figure out.

I use the following object:

function Padder(len, pad) {
  if (len === undefined) {
    len = 1;
  } else if (pad === undefined) {
    pad = '0';
  }

  var pads = '';
  while (pads.length < len) {
    pads += pad;
  }

  this.pad = function (what) {
    var s = what.toString();
    return pads.substring(0, pads.length - s.length) + s;
  };
}

With it you can easily define different "paddings":

var zero4 = new Padder(4);
zero4.pad(12); // "0012"
zero4.pad(12345); // "12345"
zero4.pad("xx"); // "00xx"
var x3 = new Padder(3, "x");
x3.pad(12); // "x12"

I am creating a map view with itemized overlays. I was creating my itemizedoverlay like this from my mapActivity:

OCItemizedOverlay currentLocationOverlay = new OCItemizedOverlay(pin,getApplicationContext);

I found that I would get the "android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application" exception when my itemizedoverlay's onTap method was triggered(when the location is tapped on the mapview).

I found that if I simply passed, 'this' instead of 'getApplicationContext()' to my constructor, the problem went away. This seems to support alienjazzcat's conclusion. weird.

UPDATE Table
SET DateColumn=GETDATE()
WHERE UserID=@UserID

If you're inserting into a table, and will always need to put the current date, I would recommend setting GETDATE() as the default value for that column, and don't allow NULLs

Instead of trying to modify the $scope within the service, you can implement a $watch within your controller to watch a property on your service for changes and then update a property on the $scope. Here is an example you might try in a controller:

angular.module('cfd')
    .controller('MyController', ['$scope', 'StudentService', function ($scope, StudentService) {

        $scope.students = null;

        (function () {
            $scope.$watch(function () {
                return StudentService.students;
            }, function (newVal, oldVal) {
                if ( newValue !== oldValue ) {
                    $scope.students = newVal;
                }
            });
        }());
    }]);

One thing to note is that within your service, in order for the students property to be visible, it needs to be on the Service object or this like so:

this.students = $http.get(path).then(function (resp) {
  return resp.data;
});

The top answer is good but it doesn't mention expression trees which explain "how" the two interfaces differ. Basically, there are two identical sets of LINQ extensions. Where(), Sum(), Count(), FirstOrDefault(), etc all have two versions: one that accepts functions and one that accepts expressions.

• The IEnumerable version signature is: Where(Func<Customer, bool> predicate)

• The IQueryable version signature is: Where(Expression<Func<Customer, bool>> predicate)

You've probably been using both of those without realizing it because both are called using identical syntax:

e.g. Where(x => x.City == "<City>") works on both IEnumerable and IQueryable

• When using Where() on an IEnumerable collection, the compiler passes a compiled function to Where()

• When using Where() on an IQueryable collection, the compiler passes an expression tree to Where(). An expression tree is like the reflection system but for code. The compiler converts your code into a data structure that describes what your code does in a format that's easily digestible.

Why bother with this expression tree thing? I just want Where() to filter my data. The main reason is that both the EF and Linq2SQL ORMs can convert expression trees directly into SQL where your code will execute much faster.

Oh, that sounds like a free performance boost, should I use AsQueryable() all over the place in that case? No, IQueryable is only useful if the underlying data provider can do something with it. Converting something like a regular List to IQueryable will not give you any benefit.

If you are using Underscore.js or Lodash, there is a function 'omit' that will do it.
http://underscorejs.org/#omit

var thisIsObject= {
    'Cow' : 'Moo',
    'Cat' : 'Meow',
    'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

Since Java 7 you can use java.util.Objects.equals(Object a, Object b):

These utilities include null-safe or null-tolerant methods

Long id1 = null;
Long id2 = 0l;
Objects.equals(id1, id2));

Other than what Alex and Evan have already stated, I would like to add that a C++ struct is not like a C struct.

In C++, a struct can have methods, inheritance, etc. just like a C++ class.

Try this:

$('#foo1').html($('#foo2').children().clone());

I'm not sure how you might do this with Node, but the general idea would be to send an HTTP HEAD request to the URL you're interested in.

HEAD

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content.

Something like this, based it on this question:

var cli = require('cli');
var http = require('http');
var url = require('url');

cli.parse();

cli.main(function(args, opts) {
        this.debug(args[0]);

        var siteUrl = url.parse(args[0]);
        var site = http.createClient(80, siteUrl.host);
        console.log(siteUrl);

        var request = site.request('HEAD', siteUrl.pathname, {'host' : siteUrl.host})
        request.end();

        request.on('response', function(response) {
                response.setEncoding('utf8');
                console.log('STATUS: ' + response.statusCode);
                response.on('data', function(chunk) {
                        console.log("DATA: " + chunk);
                });
        });
});

You should check out OGX.List which has built in filtering methods and extends the standard javascript array (and also grouping, sorting and finding). Here's a list of operators it supports for the filters:

'eq' //Equal to
'eqjson' //For deep objects, JSON comparison, equal to
'neq' //Not equal to
'in' //Contains
'nin' //Doesn't contain
'lt' //Lesser than
'lte' //Lesser or equal to
'gt' //Greater than
'gte' //Greater or equal to
'btw' //Between, expects value to be array [_from_, _to_]
'substr' //Substring mode, equal to, expects value to be array [_from_, _to_, _niddle_]
'regex' //Regex match

You can use it this way

  let list = new OGX.List(your_array);
  list.addFilter('price', 'btw', 100, 500);
  list.addFilter('sqft', 'gte', 500);
  let filtered_list = list.filter();

Or even this way

  let list = new OGX.List(your_array);
  let filtered_list = list.get({price:{btw:[100,500]}, sqft:{gte:500}});

Or as a one liner

   let filtered_list = new OGX.List(your_array).get({price:{btw:[100,500]}, sqft:{gte:500}});

The problem you have is related to TCP streaming nature.

The fact that you sent 100 Bytes (for example) from the server doesn't mean you will read 100 Bytes in the client the first time you read. Maybe the bytes sent from the server arrive in several TCP segments to the client.

You need to implement a loop in which you read until the whole message was received. Let me provide an example with DataInputStream instead of BufferedinputStream. Something very simple to give you just an example.

Let's suppose you know beforehand the server is to send 100 Bytes of data.

In client you need to write:

byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";

try 
{
    DataInputStream in = new DataInputStream(clientSocket.getInputStream());

    while(!end)
    {
        int bytesRead = in.read(messageByte);
        dataString += new String(messageByte, 0, bytesRead);
        if (dataString.length == 100)
        {
            end = true;
        }
    }
    System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
    e.printStackTrace();
}

Now, typically the data size sent by one node (the server here) is not known beforehand. Then you need to define your own small protocol for the communication between server and client (or any two nodes) communicating with TCP.

The most common and simple is to define TLV: Type, Length, Value. So you define that every message sent form server to client comes with:

• 1 Byte indicating type (For example, it could also be 2 or whatever).
• 1 Byte (or whatever) for length of message
• N Bytes for the value (N is indicated in length).

So you know you have to receive a minimum of 2 Bytes and with the second Byte you know how many following Bytes you need to read.

This is just a suggestion of a possible protocol. You could also get rid of "Type".

So it would be something like:

byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";

try 
{
    DataInputStream in = new DataInputStream(clientSocket.getInputStream());
    int bytesRead = 0;

    messageByte[0] = in.readByte();
    messageByte[1] = in.readByte();

    int bytesToRead = messageByte[1];

    while(!end)
    {
        bytesRead = in.read(messageByte);
        dataString += new String(messageByte, 0, bytesRead);
        if (dataString.length == bytesToRead )
        {
            end = true;
        }
    }
    System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
    e.printStackTrace();
}

The following code compiles and looks better. It assumes the first two bytes providing the length arrive in binary format, in network endianship (big endian). No focus on different encoding types for the rest of the message.

import java.nio.ByteBuffer;
import java.io.DataInputStream;
import java.net.ServerSocket;
import java.net.Socket;

class Test
{
    public static void main(String[] args)
    {
        byte[] messageByte = new byte[1000];
        boolean end = false;
        String dataString = "";

        try 
        {
            Socket clientSocket;
            ServerSocket server;

            server = new ServerSocket(30501, 100);
            clientSocket = server.accept();

            DataInputStream in = new DataInputStream(clientSocket.getInputStream());
            int bytesRead = 0;

            messageByte[0] = in.readByte();
            messageByte[1] = in.readByte();
            ByteBuffer byteBuffer = ByteBuffer.wrap(messageByte, 0, 2);

            int bytesToRead = byteBuffer.getShort();
            System.out.println("About to read " + bytesToRead + " octets");

            //The following code shows in detail how to read from a TCP socket

            while(!end)
            {
                bytesRead = in.read(messageByte);
                dataString += new String(messageByte, 0, bytesRead);
                if (dataString.length() == bytesToRead )
                {
                    end = true;
                }
            }

            //All the code in the loop can be replaced by these two lines
            //in.readFully(messageByte, 0, bytesToRead);
            //dataString = new String(messageByte, 0, bytesToRead);

            System.out.println("MESSAGE: " + dataString);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}

If your date is in the format of a string use the explode function

    array explode ( string $delimiter , string $string [, int $limit ] )
//In the case of your code

$length = strrpos($oldDate," ");
$newDate = explode( "-" , substr($oldDate,$length));
$output = $newDate[2]."/".$newDate[1]."/".$newDate[0];

Hope the above works now

The headers are entirely encrypted. The only information going over the network 'in the clear' is related to the SSL setup and D/H key exchange. This exchange is carefully designed not to yield any useful information to eavesdroppers, and once it has taken place, all data is encrypted.

I had this problem and the problem was bootstrap.js wasn't load in Yii2 framework.First check is jquery loaded in inspect and then check bootstrap.js is loaded?If you used any tooltip Popper.js is needed before bootsrap.js.

You could use a Polygon Clipping algorithm to find the intersection between two polygons. However these tend to be complicated algorithms when all of the edge cases are taken into account.

One implementation of polygon clipping that you can use your favorite search engine to look for is Weiler-Atherton. wikipedia article on Weiler-Atherton

Alan Murta has a complete implementation of a polygon clipper GPC.

Edit:

Another approach is to first divide each polygon into a set of triangles, which are easier to deal with. The Two-Ears Theorem by Gary H. Meisters does the trick. This page at McGill does a good job of explaining triangle subdivision.

IE can set username and password proxies, so maybe setting it there and import does work

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d name:port
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyUser /t REG_SZ /d username
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyPass /t REG_SZ /d password
netsh winhttp import proxy source=ie

You need to use the css-property font-face to declare your font. Have a look at this fancy site: http://www.font-face.com/

Example:

@font-face {
  font-family: MyHelvetica;
  src: local("Helvetica Neue Bold"),
       local("HelveticaNeue-Bold"),
       url(MgOpenModernaBold.ttf);
  font-weight: bold;
}

See also: MDN @font-face

template:

<input [(ngModel)]="componentField" type="file" (change)="fileChange($event)" placeholder="Upload file">

component:

fileChange(event) {
        alert(this.torrentFileValue);
        this.torrentFileValue = '';
    }
}

One can also make use of the tracemalloc module from the Python standard library. It seems to work well for objects whose class is implemented in C (unlike Pympler, for instance).

I had the same problem with something like

@foreach (var item in Model)
{
    @Html.DisplayFor(m => !item.IsIdle, "BoolIcon")
}

I solved this just by doing

@foreach (var item in Model)
{
    var active = !item.IsIdle;
    @Html.DisplayFor(m => active , "BoolIcon")
}

When you know the trick, it's simple.

The difference is that, in the first case, I passed a method as a parameter whereas in the second case, it's an expression.

There is a plugin for jQuery called inview which adds a new "inview" event.

Here is some code for a jQuery plugin that doesn't use events:

$.extend($.expr[':'],{
    inView: function(a) {
        var st = (document.documentElement.scrollTop || document.body.scrollTop),
            ot = $(a).offset().top,
            wh = (window.innerHeight && window.innerHeight < $(window).height()) ? window.innerHeight : $(window).height();
        return ot > st && ($(a).height() + ot) < (st + wh);
    }
});

(function( $ ) {
    $.fn.inView = function() {
        var st = (document.documentElement.scrollTop || document.body.scrollTop),
        ot = $(this).offset().top,
        wh = (window.innerHeight && window.innerHeight < $(window).height()) ? window.innerHeight : $(window).height();

        return ot > st && ($(this).height() + ot) < (st + wh);
    };
})( jQuery );

I found this in a comment here ( http://remysharp.com/2009/01/26/element-in-view-event-plugin/ ) by a bloke called James

To set up system wide scope you need to use the

/etc/environment file sudo gedit /etc/environment

is the location where you can define any environment variable. It can be visible in the whole system scope. After variable is defined system need to be restarted.

EXAMPLE :

sudo gedit /etc/environment

Add like following :

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
JAVA_HOME="/opt/jdk1.6.0_45/"

Possible Cause #1 (same as the first 3 answers for this question): Project Structure Settings

1. File > Project Structure > Under Project Settings, go to Project > set Project SDK to 1.8 (with version 65 or above, latest is 112) and set Project Language Level to 8.

2. File > Project Structure > Under Platform Settings, go to Project > ensure that your JDK home path is set to 1.8 (with version 65 or above, latest is 112).

If the above does not work, check the target bytecode version of your compiler and move on to Possible Cause #2.

Possible Cause #2: Compiler

1. File > Settings > Build, Execution, Deployment > Under Compiler, go to Java Compiler > set your Project Bytecode Version to 1.8, as well as all the Target Bytecode Version for your modules. Click Apply and hit OK. Restart your IntelliJ IDE. Lambda expression was accepted in my IDE at this point.

Best wishes :)

Simply follow three steps;

1. Clear npm cache forcefully:

   npm cache clean -f

2. Install n package globally using npm:

   npm install -g n

3. Install from any of three options:

   a. sudo n stable (get the stable version)

   b. sudo n latest (get the latest version of node)

   c. sudo n x.x.x (get the specific version of node)

int(hexstring, 16) does the trick, and works with and without the 0x prefix:

>>> int("a", 16)
10
>>> int("0xa", 16)
10

A stub, in this context, means a mock implementation.

That is, a simple, fake implementation that conforms to the interface and is to be used for testing.

The command below will search all the files recursively whose name matches the search pattern and will replace the string:

find /path/to/searchdir/ -name "serachpatter" -type f | xargs sed -i 's/stringone/StrIngTwo/g'

Also if you want to limit the depth of recursion you can put the limits as well:

find /path/to/searchdir/ -name "serachpatter" -type f -maxdepth 4 -mindepth 2 | xargs sed -i 's/stringone/StrIngTwo/g'

Most of the time prod mode is not needed during development time. So our workaround is to only enable it when it is NOT localhost.

In your browsers' main.ts where you define your root AppModule:

const isLocal: boolean = /localhost/.test(document.location.host);
!isLocal && enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

The isLocal can also be used for other purposes like enableTracing for the RouterModule for better debugging stack trace during dev phase.

For future reference to people who come here. after you run the command that was given in the third answer here(I am using now Laravel 5.3).

php artisan config:cache

You may encounter this problem:

[ReflectionException]
Class view does not exist

In that case, you need to add it back manually to your provider list under the app.php file. GO-TO: app->config->app.php->'providers[]' and add it, like so:

Illuminate\View\ViewServiceProvider::class,

Hope That helps someone.

async() => {
let body = await model.find().or([
  { name: 'something'},
  { nickname: 'somethang'}
]).exec();
console.log(body);
}
/* Gives an array of the searched query!
returns [] if not found */

It is a generic type parameter, see Generics documentation.

T is not a reserved keyword. T, or any given name, means a type parameter. Check the following method (just as a simple example).

T GetDefault<T>()
{
    return default(T);
}

Note that the return type is T. With this method you can get the default value of any type by calling the method as:

GetDefault<int>(); // 0
GetDefault<string>(); // null
GetDefault<DateTime>(); // 01/01/0001 00:00:00
GetDefault<TimeSpan>(); // 00:00:00

.NET uses generics in collections, ... example:

List<int> integerList = new List<int>();

This way you will have a list that only accepts integers, because the class is instancited with the type T, in this case int, and the method that add elements is written as:

public class List<T> : ...
{
    public void Add(T item);
}

Some more information about generics.

You can limit the scope of the type T.

The following example only allows you to invoke the method with types that are classes:

void Foo<T>(T item) where T: class
{
}

The following example only allows you to invoke the method with types that are Circle or inherit from it.

void Foo<T>(T item) where T: Circle
{
}

And there is new() that says you can create an instance of T if it has a parameterless constructor. In the following example T will be treated as Circle, you get intellisense...

void Foo<T>(T item) where T: Circle, new()
{
    T newCircle = new T();
}

As T is a type parameter, you can get the object Type from it. With the Type you can use reflection...

void Foo<T>(T item) where T: class
{
    Type type = typeof(T);
}

As a more complex example, check the signature of ToDictionary or any other Linq method.

public static Dictionary<TKey, TSource> ToDictionary<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector);

There isn't a T, however there is TKey and TSource. It is recommended that you always name type parameters with the prefix T as shown above.

You could name TSomethingFoo if you want to.

This article helps. In particular, this section:

-File

Runs the specified script in the local scope ("dot-sourced"), so that the functions and variables that the script creates are available in the current session. Enter the script file path and any parameters. File must be the last parameter in the command, because all characters typed after the File parameter name are interpreted as the script file path followed by the script parameters.

i.e.

powershell.exe -File "C:\myfile.ps1" arg1 arg2 arg3

means run the file myfile.ps1 and arg1 arg2 & arg3 are the parameters for the PowerShell script.

You could try

moment().add(1, 'M').subtract(1, 'day').format('DD-MM-YYYY')

Execution Timeout is 90 seconds for .NET Framework 1.0 and 1.1, 110 seconds otherwise.

If you need to change defult settings you need to do it in your web.config under <httpRuntime>

<httpRuntime executionTimeout = "number(in seconds)"/>

But Remember:

This time-out applies only if the debug attribute in the compilation element is False.

user2532030's answer is the correct and most simple answer.

I just want to add, that in the case, where the value of the determining cell is not suitable for a RegEx-match, I found the following syntax to work the same, only with numerical values, relations et.c.:

[Custom formula is]
=$B$2:$B = "Complete"
Range: A2:Z1000

If column 2 of any row (row 2 in script, but the leading $ means, this could be any row) textually equals "Complete", do X for the Range of the entire sheet (excluding header row (i.e. starting from A2 instead of A1)).

But obviously, this method allows also for numerical operations (even though this does not apply for op's question), like:

=$B$2:$B > $C$2:$C

So, do stuff, if the value of col B in any row is higher than col C value.

One last thing: Most likely, this applies only to me, but I was stupid enough to repeatedly forget to choose Custom formula is in the drop-down, leaving it at Text contains. Obviously, this won't float...

You would need to download all of the transport stream (.ts) files, and concatenate them into a single mpeg for playback. Transport streams such as this have associated playlist files (.m3u8) that list all of the .ts files that you need to download and concatenate. If available, there may be a secondary .m3u8 playlist that will separately list subtitle steam files (.vtt).

Some scenarios don't always allow developers to switch scripting language.

My preference is definitely for JavaScript (and I have used it in new projects). However, maintaining older projects is still required and necessary. Unfortunately, these are written in VBScript.

So even though this solution doesn't offer true "try/catch" functionaility, the result is the same, and that's good enough for me to get the job done.

In Bootstrap 4 alpha-6 version, As navbar is using flex model, you can use justify-content-end in parent's div and remove mr-auto.

<div class="collapse navbar-collapse justify-content-end" id="navbarText">
  <ul class="navbar-nav">
    <li class="nav-item active">
      <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
      <a class="nav-link disabled" href="#">Disabled</a>
    </li>
  </ul>
</div>

This works like a charm :)

Defining static properties and methods of a class is described in 8.2.1 of the Typescript Language Specification:

class Point { 
  constructor(public x: number, public y: number) { 
    throw new Error('cannot instantiate using a static class');
  } 
  public distance(p: Point) { 
    var dx = this.x - p.x; 
    var dy = this.y - p.y; 
    return Math.sqrt(dx * dx + dy * dy); 
  } 
  static origin = new Point(0, 0); 
  static distance(p1: Point, p2: Point) { 
    return p1.distance(p2); 
  } 
}

Small edit to @seengee answer: In order to work, you need curly braces around the variable, otherwise you'll get an error.

what about using CSS on UIWebView? something like

<style type="text/css">
<!—-
    * {
        -webkit-user-select: none;
    }
-->
</style>

also you can read detail about block copy-paste using CSS http://rakaz.nl/2009/09/iphone-webapps-101-getting-safari-out-of-the-way.html

I know this question is old, but between all the answers, I miss one that is a common approach for this use-case in XSLT development.

I am imagining that the missing code from the OP looks something like this:

<xsl:template match="category">
    <xsl:choose>
        <xsl:when test="categoryName !=null">
            <xsl:value-of select="categoryName " />
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="other" />
        </xsl:otherwise>
    </xsl:choose>
</category>

And that the input looks something like this:

<categories>
    <category>
       <categoryName>Books</categoryName>
    </category>
    <category>
       <categoryName>Magazines</categoryName>
       <categoryName>Periodicals</categoryName>
       <categoryName>Journals</categoryName>
    </category>
    <category>
        <categoryName><!-- please fill in category --></categoryName>
    </category>
    <category>
        <categoryName />
    </category>
    <category />
</categories>

I.e., I assume there can be zero, empty, single or multiple categoryName elements. To deal with all these cases using xsl:choose-style constructs, or in other words, imperatively, is quickly getting messy (even more so if elements can be at different levels!). A typical programming idiom in XSLT is using templates (hence the T in XSLT), which is declarative programming, not imperative (you don't tell the processor what to do, you just tell what you want output if certain conditions are met). For this use-case, that can look something like the following:

<!-- positive test, any category with a valid categoryName -->
<xsl:template match="category[categoryName[text()]]">
    <xsl:apply-templates />
</xsl:template>

<!-- any other category (without categoryName, "null", with comments etc) -->
<xsl:template match="category">
    <xsl:text>Category: Other</xsl:text>
</xsl:template>

<!-- matching the categoryName itself for easy handling of multiple names -->
<xsl:template match="categoryName">
    <xsl:text>Category: </xsl:text>
    <xsl:value-of select="." />
</xsl:template>

This works (with any XSLT version), because the first one above has a higher precedence (it has a predicate). The "fall-through" matching template, the second one, catches anything that is not valid. The third one then takes care of outputting the categoryName value in a proper way.

Note that in this scenario there is no need to specifially match categories or category, because the processor will automatically process all children, unless we tell it otherwise (in this example, the second and third template do not further process the children, because there is no xsl:apply-templates in them).

This approach is more easily extendible then the imperative approach, because it automically deals with multiple categories and it can be expanded for other elements or exceptions by just adding another matching template. Programming without if-branches.

Note: there is no such thing as null in XML. There is xsi:nil, but that is rarely used, especially rarely in untyped scenarios without a schema of some sort.

try also resizing the browser tab to see it in action

I solved it with window.length. But with this solution you can take current error (X-Frame or 404).

iframe.onload = event => {
   const isLoaded = event.target.contentWindow.window.length // 0 or 1
}

MSDN

I know that its bit old Q but if u get here by searching a solution so i got a nice one via jquery

  jQuery('a[target^="_new"]').click(function() {
    var width = window.innerWidth * 0.66 ;
    // define the height in
    var height = width * window.innerHeight / window.innerWidth ;
    // Ratio the hight to the width as the user screen ratio
    window.open(this.href , 'newwindow', 'width=' + width + ', height=' + height + ', top=' + ((window.innerHeight - height) / 2) + ', left=' + ((window.innerWidth - width) / 2));

});

it will open all the <a target="_new"> in a new window

EDIT:

1st, I did some little changes in the original code now it open the new window perfectly followed the user screen ratio (for landscape desktops)

but, I would like to recommend you to use the following code that open the link in new tab if you in mobile (thanks to zvona answer in other question):

jQuery('a[target^="_new"]').click(function() {
    return openWindow(this.href);
}


function openWindow(url) {

    if (window.innerWidth <= 640) {
        // if width is smaller then 640px, create a temporary a elm that will open the link in new tab
        var a = document.createElement('a');
        a.setAttribute("href", url);
        a.setAttribute("target", "_blank");

        var dispatch = document.createEvent("HTMLEvents");
        dispatch.initEvent("click", true, true);

        a.dispatchEvent(dispatch);
    }
    else {
        var width = window.innerWidth * 0.66 ;
        // define the height in
        var height = width * window.innerHeight / window.innerWidth ;
        // Ratio the hight to the width as the user screen ratio
        window.open(url , 'newwindow', 'width=' + width + ', height=' + height + ', top=' + ((window.innerHeight - height) / 2) + ', left=' + ((window.innerWidth - width) / 2));
    }
    return false;
}

Use iloc to access by position (rather than label):

In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])

In [12]: df
Out[12]: 
   A  B
a  1  2
b  3  4

In [13]: df.iloc[0]  # first row in a DataFrame
Out[13]: 
A    1
B    2
Name: a, dtype: int64

In [14]: df['A'].iloc[0]  # first item in a Series (Column)
Out[14]: 1

I modified @Alisa's code and used cProfile to show why list comprehension is faster:

from functools import reduce
import datetime

def reduce_(numbers):
    return reduce(lambda sum, next: sum + next * next, numbers, 0)

def for_loop(numbers):
    a = []
    for i in numbers:
        a.append(i*2)
    a = sum(a)
    return a

def map_(numbers):
    sqrt = lambda x: x*x
    return sum(map(sqrt, numbers))

def list_comp(numbers):
    return(sum([i*i for i in numbers]))

funcs = [
        reduce_,
        for_loop,
        map_,
        list_comp
        ]

if __name__ == "__main__":
    # [1, 2, 5, 3, 1, 2, 5, 3]
    import cProfile
    for f in funcs:
        print('=' * 25)
        print("Profiling:", f.__name__)
        print('=' * 25)
        pr = cProfile.Profile()
        for i in range(10**6):
            pr.runcall(f, [1, 2, 5, 3, 1, 2, 5, 3])
        pr.create_stats()
        pr.print_stats()

IMHO:

• reduce and map are in general pretty slow. Not only that, using sum on the iterators that map returned is slow, compared to suming a list
• for_loop uses append, which is of course slow to some extent
• list-comprehension not only spent the least time building the list, it also makes sum much quicker, in contrast to map

If you are constructing the connection string within the app then you would use your command of connString. If you are using a connection string in the web config. Then you use the "name" of that string.

Unmodifiable collections are usually read-only views (wrappers) of other collections. You can't add, remove or clear them, but the underlying collection can change.

Immutable collections can't be changed at all - they don't wrap another collection - they have their own elements.

Here's a quote from guava's ImmutableList

Unlike Collections.unmodifiableList(java.util.List<? extends T>), which is a view of a separate collection that can still change, an instance of ImmutableList contains its own private data and will never change.

So, basically, in order to get an immutable collection out of a mutable one, you have to copy its elements to the new collection, and disallow all operations.

The file msrdo20.dll is missing from the installation.

According to the Support Statement for Visual Basic 6.0 on Windows Vista, Windows Server 2008 and Windows 7 this file should be distributed with the application.

I'm not sure why it isn't, but my solution is to place the file somewhere on the machine, and register it using regsvr32 in the command line, eg:

regsvr32 c:\windows\system32\msrdo20.dll

In an ideal world you would package this up with the redistributable.

As mentioned by Seeker, the problem could have been that you setup the click() function too soon. From your code snippet, we cannot know where you placed the script and whether it gets run at the right time.

An important point is to run such scripts after the document is ready. This is done by placing the click() initialization within that other function as in:

jQuery(document).ready(function()
  {
    jQuery("body").click(function()
      {
        // ... your click code here ...
      });
  });

This is usually the best method, especially if you include your JavaScript code in your <head> tag. If you include it at the very bottom of the page, then the ready() function is less important, but it may still be useful.

If this is for an intranet application and all of the clients use DHCP, you can query the DHCP server for the MAC address for a given IP address.

If you use windows server, you can change Environment Variable, restart server to apply new Environment Value and start Elastic Service. More detail in Install Elastic in Windows Server

You can use the Gson library for parsing

void getJson() throws IOException {
    HttpClient  httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet("some url of json");
    HttpResponse httpResponse = httpClient.execute(httpGet);
    String response = EntityUtils.toString(httpResponse.getEntity());

    Gson gson = new Gson();
    MyClass myClassObj = gson.fromJson(response, MyClass.class);

}

here is sample json file which is fetchd from server

{
"id":5,
"name":"kitkat",
"version":"4.4"
}

here is my class

class MyClass{
int id;
String name;
String version;
}

Use Math.Ceiling to round up

Math.Ceiling(0.5); // 1

Use Math.Round to just round

1. Allows casts to be found easily in your code using grep or similar tools.
2. Makes it explicit what kind of cast you are doing, and engaging the compiler's help in enforcing it. If you only want to cast away const-ness, then you can use const_cast, which will not allow you to do other types of conversions.
3. Casts are inherently ugly -- you as a programmer are overruling how the compiler would ordinarily treat your code. You are saying to the compiler, "I know better than you." That being the case, it makes sense that performing a cast should be a moderately painful thing to do, and that they should stick out in your code, since they are a likely source of problems.

See Effective C++ Introduction

    final String url = "some/url";

instead of:

    final JSONObject jsonBody = "{\"type\":\"example\"}";

you can use:

  JSONObject jsonBody = new JSONObject();
    try {
        jsonBody.put("type", "my type");
    } catch (JSONException e) {
        e.printStackTrace();
    }
new JsonObjectRequest(url, jsonBody, new Response.Listener<JSONObject>() { ... });

There is no need for an UDF here. Column already provides cast method with DataType instance :

from pyspark.sql.types import DoubleType

changedTypedf = joindf.withColumn("label", joindf["show"].cast(DoubleType()))

or short string:

changedTypedf = joindf.withColumn("label", joindf["show"].cast("double"))

where canonical string names (other variations can be supported as well) correspond to simpleString value. So for atomic types:

from pyspark.sql import types 

for t in ['BinaryType', 'BooleanType', 'ByteType', 'DateType', 
          'DecimalType', 'DoubleType', 'FloatType', 'IntegerType', 
           'LongType', 'ShortType', 'StringType', 'TimestampType']:
    print(f"{t}: {getattr(types, t)().simpleString()}")

BinaryType: binary
BooleanType: boolean
ByteType: tinyint
DateType: date
DecimalType: decimal(10,0)
DoubleType: double
FloatType: float
IntegerType: int
LongType: bigint
ShortType: smallint
StringType: string
TimestampType: timestamp

and for example complex types

types.ArrayType(types.IntegerType()).simpleString()   

'array<int>'

types.MapType(types.StringType(), types.IntegerType()).simpleString()

'map<string,int>'

Change data type of DataFrame column:

To int:

df.column_name = df.column_name.astype(np.int64)

To str:

df.column_name = df.column_name.astype(str)

Try this:

/^stop.*$/

Explanation:

• / charachters delimit the regular expression (i.e. they are not part of the Regex per se)
• ^ means match at the beginning of the line
• . followed by * means match any character (.), any number of times (*)
• $ means to the end of the line

If you would like to enforce that stop be followed by a whitespace, you could modify the RegEx like so:

/^stop\s+.*$/

• \s means any whitespace character
• + following the \s means there has to be at least one whitespace character following after the stop word

Note: Also keep in mind that the RegEx above requires that the stop word be followed by a space! So it wouldn't match a line that only contains: stop

I had the same problem earlier today. I could not figure out why the class file I was trying to reference was not being seen by the compiler. I had recently changed the namespace of the class file in question to a different but already existing namespace. (I also had using references to the class's new and previous namespaces where I was trying to instantiate it)

Where the compiler was telling me I was missing a reference when trying to instantiate the class, I right clicked and hit "generate class stub". Once Visual Studio generated a class stub for me, I coped and pasted the code from the old class file into this stub, saved the stub and when I tried to compile again it worked! No issues.

Might be a solution specific to my build, but its worth a try.

I know I am late, but if you want to know the easiest way, you could do a code like this:

number = 100
right_questions = 1
control = 100
c = control / number
cc = right_questions * c
print float(cc)

You can change up the number score, and right_questions. It will tell you the percent.

Both are valid but I normally choose interfaces. A class (abstract or not) is not needed if there is no implementations.

As an advise, try to choose the location of your constants wisely, they are part of your external contract. Do not put every single constant in one file.

For example, if a group of constants is only used in one class or one method put them in that class, the extended class or the implemented interfaces. If you do not take care you could end up with a big dependency mess.

Sometimes an enumeration is a good alternative to constants (Java 5), take look at: http://docs.oracle.com/javase/1.5.0/docs/guide/language/enums.html

You can also do this

[Flags]
public enum MyEnum
{
    None   = 0,
    First  = 1 << 0,
    Second = 1 << 1,
    Third  = 1 << 2,
    Fourth = 1 << 3
}

I find the bit-shifting easier than typing 4,8,16,32 and so on. It has no impact on your code because it's all done at compile time

tl;dr

$ cat /tmp/so.json | underscore select '.Messages .Body' 
["172.16.1.42|/home/480/1234/5-12-2013/1234.toSort"]

Javascript CLI tools

You can use Javascript CLI tools like

• underscore-cli:
• json:select(): CSS-like selectors for JSON.

Example

Select all name children of a addons:

underscore select ".addons > .name"

The underscore-cli provide others real world examples as well as the json:select() doc.

In my case I had duplicated a class file! Found it by using the bottom search field at the right side bar of Xcode, so to solve it remove reference of one of them

Attempts of abrupt thread termination are well-known bad programming practice and evidence of poor application design. All threads in the multithreaded application explicitly and implicitly share the same process state and forced to cooperate with each other to keep it consistent, otherwise your application will be prone to the bugs which will be really hard to diagnose. So, it is a responsibility of developer to provide an assurance of such consistency via careful and clear application design.

There are two main right solutions for the controlled threads terminations:

• Use of the shared volatile flag
• Use of the pair of Thread.interrupt() and Thread.interrupted() methods.

Good and detailed explanation of the issues related to the abrupt threads termination as well as examples of wrong and right solutions for the controlled threads termination can be found here:

Use the Pandas library to create a dataframe of the csv data.
Name the fields either by including them in the csv file's first line or in code by using the dataframe's columns method.
Then create a list of model instances.
Finally use the django method .bulk_create() to send your list of model instances to the database table.

The read_csv function in pandas is great for reading csv files and gives you lots of parameters to skip lines, omit fields, etc.

import pandas as pd

tmp_data=pd.read_csv('file.csv',sep=';')
#ensure fields are named~ID,Product_ID,Name,Ratio,Description
#concatenate name and Product_id to make a new field a la Dr.Dee's answer
products = [
    Product(
        name = tmp_data.ix[row]['Name'] 
        description = tmp_data.ix[row]['Description'],
        price = tmp_data.ix[row]['price'],
    )
    for row in tmp_data['ID']
]
Product.objects.bulk_create(products)

I was using the answer by mmrs151 but saving each row (instance) was very slow and any fields containing the delimiting character (even inside of quotes) were not handled by the open() -- line.split(';') method.

Pandas has so many useful caveats, it is worth getting to know
