As rcs stated, cex will do the job in base graphics package. I reckon that you're not willing to do your graph in ggplot2 but if you do, there's a size aesthetic attribute, that you can easily control (ggplot2 has user-friendly function arguments: instead of typing cex (character expansion), in ggplot2 you can type e.g. size = 2 and you'll get 2mm point).

Here's the example:

### base graphics ###
plot(mpg ~ hp, data = mtcars, pch = 16, cex = .9)

### ggplot2 ###
# with qplot()
qplot(mpg, hp, data = mtcars, size = I(2))
# or with ggplot() + geom_point()
ggplot(mtcars, aes(mpg, hp), size = 2) + geom_point()
# or another solution:
ggplot(mtcars, aes(mpg, hp)) + geom_point(size = 2)

You can always use the plot() function like so:

import matplotlib.pyplot as plt

import numpy as np

x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]
plt.figure()
for y in ys:
    plt.plot(x, y, 'o')
plt.show()

Here's another way: this adds a circle to the current axes, plot or image or whatever :

from matplotlib.patches import Circle  # $matplotlib/patches.py

def circle( xy, radius, color="lightsteelblue", facecolor="none", alpha=1, ax=None ):
    """ add a circle to ax= or current axes
    """
        # from .../pylab_examples/ellipse_demo.py
    e = Circle( xy=xy, radius=radius )
    if ax is None:
        ax = pl.gca()  # ax = subplot( 1,1,1 )
    ax.add_artist(e)
    e.set_clip_box(ax.bbox)
    e.set_edgecolor( color )
    e.set_facecolor( facecolor )  # "none" not None
    e.set_alpha( alpha )

(The circles in the picture get squashed to ellipses because imshow aspect="auto" ).

Here's an easier way of doing this (source: here):

import matplotlib.pyplot as plt
from numpy.random import rand


fig, ax = plt.subplots()
for color in ['red', 'green', 'blue']:
    n = 750
    x, y = rand(2, n)
    scale = 200.0 * rand(n)
    ax.scatter(x, y, c=color, s=scale, label=color,
               alpha=0.3, edgecolors='none')

ax.legend()
ax.grid(True)

plt.show()

And you'll get this:

Take a look at here for legend properties

This might be useful when you need individually annotate in different time (I mean, not in a single for loop)

ax = plt.gca()
ax.annotate('your_lable', (x,y)) 

where x and y are the your target coordinate and type is float/int.

To track down the correct parameters you need to go first to ?plot.default, which refers you to ?par and ?axis:

plot(1, 1 ,xlab="x axis", ylab="y axis",  pch=19,
           col.lab="red", cex.lab=1.5,    #  for the xlab and ylab
           col="green")                   #  for the points

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

For just plotting a vector, you should use the following command:

text(your.vector, labels=your.labels, cex= labels.size, pos=labels.position)

Use the following code it worked for me:

# Create the figure
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Generate the values
x_vals = X_iso[:, 0:1]
y_vals = X_iso[:, 1:2]
z_vals = X_iso[:, 2:3]

# Plot the values
ax.scatter(x_vals, y_vals, z_vals, c = 'b', marker='o')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')

plt.show()

while X_iso is my 3-D array and for X_vals, Y_vals, Z_vals I copied/used 1 column/axis from that array and assigned to those variables/arrays respectively.

If removing \0 from the end of string is impossible, you can add your own character for each string you encode, and remove it on decode.

ArrayAdapter<String> should work.

i.e.:

Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>
            (this, android.R.layout.simple_spinner_item,
           spinnerArray); //selected item will look like a spinner set from XML
spinnerArrayAdapter.setDropDownViewResource(android.R.layout
                                                     .simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter); 

Check where your clang is located:

which clang

It should be somewhere under /usr/bin/clang. In my case from old times it was coming from Miniconda that was put artificially on the command line PATH. Fix that so that clang comes from Xcode and that should bring you forward.

I hope this will help you:

final TextView t1=new TextView(this); 
t1.setText("Hello Android");        
final SeekBar sk=(SeekBar) findViewById(R.id.seekBar1);     
sk.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {       

    @Override       
    public void onStopTrackingTouch(SeekBar seekBar) {      
        // TODO Auto-generated method stub      
    }       

    @Override       
    public void onStartTrackingTouch(SeekBar seekBar) {     
        // TODO Auto-generated method stub      
    }       

    @Override       
    public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {     
        // TODO Auto-generated method stub      

        t1.setTextSize(progress);
        Toast.makeText(getApplicationContext(), String.valueOf(progress),Toast.LENGTH_LONG).show();

    }       
});             

My problem was similar and this worked for me:

$('body').on('change', '.radioClassNameHere', function() { ...

self.navigationController != nil would mean it's in a navigation stack.

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

Another simpler solution is that you may also right click on "C:\Windows\System32\cmd.exe" and choose "Run as Administrator" then you can run any app as administrator without providing any password.

Like this:

@Html.DropDownListFor(model => model.Status, new List<SelectListItem> 
       { new SelectListItem{Text="Active", Value="True"},
         new SelectListItem{Text="Deactive", Value="False"}},"Select One")

If you want Active to be selected by default then use Selected property of SelectListItem:

@Html.DropDownListFor(model => model.Status, new List<SelectListItem> 
           { new SelectListItem{Text="Active", Value="True",Selected=true},
             new SelectListItem{Text="Deactive", Value="False"}},"Select One")

If using SelectList, then you have to use this overload and specify SelectListItem Value property which you want to set selected:

@Html.DropDownListFor(model => model.title, 
                     new SelectList(new List<SelectListItem>
  {
      new SelectListItem { Text = "Active" , Value = "True"},
      new SelectListItem { Text = "InActive", Value = "False" }
  },
    "Value", // property to be set as Value of dropdown item
    "Text",  // property to be used as text of dropdown item
    "True"), // value that should be set selected of dropdown
     new { @class = "form-control" })

Okay i might have some even different approach.

I am aware that it won't suit everybody but nontheless someone might find it useful.

For those who do not want to pupup a new window, and like me, are concerned about css styles this is what i came up with:

I wrapped view of my app into additional container, which is being hidden when printing and there is additional container for what needs to be printed which is shown when is printing.

Below working example:

var app = angular.module('myApp', []);_x000D_
 app.controller('myCtrl', function($scope) {_x000D_
  _x000D_
    $scope.people = [{_x000D_
      "id" : "000",_x000D_
      "name" : "alfred"_x000D_
    },_x000D_
    {_x000D_
      "id" : "020",_x000D_
      "name" : "robert"_x000D_
    },_x000D_
    {_x000D_
      "id" : "200",_x000D_
      "name" : "me"_x000D_
    }];_x000D_
_x000D_
    $scope.isPrinting = false;_x000D_
  $scope.printElement = {};_x000D_
  _x000D_
  $scope.printDiv = function(e)_x000D_
  {_x000D_
   console.log(e);_x000D_
   $scope.printElement = e;_x000D_
   _x000D_
   $scope.isPrinting = true;_x000D_
      _x000D_
      //does not seem to work without toimeouts_x000D_
   setTimeout(function(){_x000D_
    window.print();_x000D_
   },50);_x000D_
   _x000D_
   setTimeout(function(){_x000D_
    $scope.isPrinting = false;_x000D_
   },50);_x000D_
   _x000D_
   _x000D_
  };_x000D_
    _x000D_
  });

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_

  </div>_x000D_
  _x000D_
  _x000D_
</div>_x000D_
 

Note that i am aware that this is not an elegant solution, and it has several drawbacks, but it has some ups as well:

• does not need a popup window
• keeps the css intact
• does not store your whole page into a var (for whatever reason you don't want to do it)

Well, whoever you are reading this, have a nice day and keep coding :)

EDIT:

If it suits your situation you can actually use:

@media print  { .noprint  { display: none; } }
@media screen { .noscreen { visibility: hidden; position: absolute; } }

instead of angular booleans to select your printing and non printing content

EDIT:

Changed the screen css because it appears that display:none breaks printiing when printing first time after a page load/refresh.

visibility:hidden approach seem to be working so far.

You are missing the ? in the second URL (Also, it should be URL-encoded to be %3F).

Also, I believe that the remaining & need to be URL, not HTML-encoded. Change &second=12&third=5 to %26second=12%26third=5 and everything should just work.

This:

&u=http://www.foobar.com/first=12&sec=25&position=2

should be:

&u=http://www.foobar.com/%3Ffirst=12%26sec=25%26position=2

Usually, instance methods are global methods. That means they are available in all instances of the class on which they were defined. In contrast, a singleton method is implemented on a single object.

Ruby stores methods in classes and all methods must be associated with a class. The object on which a singleton method is defined is not a class (it is an instance of a class). If only classes can store methods, how can an object store a singleton method? When a singleton method is created, Ruby automatically creates an anonymous class to store that method. These anonymous classes are called metaclasses, also known as singleton classes or eigenclasses. The singleton method is associated with the metaclass which, in turn, is associated with the object on which the singleton method was defined.

If multiple singleton methods are defined within a single object, they are all stored in the same metaclass.

class Zen
end

z1 = Zen.new
z2 = Zen.new

class << z1
  def say_hello
    puts "Hello!"
  end
end

z1.say_hello    # Output: Hello!
z2.say_hello    # Output: NoMethodError: undefined method `say_hello'…

In the above example, class << z1 changes the current self to point to the metaclass of the z1 object; then, it defines the say_hello method within the metaclass.

Classes are also objects (instances of the built-in class called Class). Class methods are nothing more than singleton methods associated with a class object.

class Zabuton
  class << self
    def stuff
      puts "Stuffing zabuton…"
    end
  end
end

All objects may have metaclasses. That means classes can also have metaclasses. In the above example, class << self modifies self so it points to the metaclass of the Zabuton class. When a method is defined without an explicit receiver (the class/object on which the method will be defined), it is implicitly defined within the current scope, that is, the current value of self. Hence, the stuff method is defined within the metaclass of the Zabuton class. The above example is just another way to define a class method. IMHO, it's better to use the def self.my_new_clas_method syntax to define class methods, as it makes the code easier to understand. The above example was included so we understand what's happening when we come across the class << self syntax.

In your project, right-click, Add Reference..., in the .NET tab, find the System.Configuration component name and click OK.

using System.Configuration tells the compiler/IntelliSense to search in that namespace for any classes you use. Otherwise, you would have to use the full name (System.Configuration.ConfigurationManager) every time. But if you don't add the reference, that namespace/class will not be found anywhere.

Note that a DLL can have any namespace, so the file System.Configuration.dll could, in theory, have the namespace Some.Random.Name. For clarity/consistency they're usually the same, but there are exceptions.

If you are using python2.7 or above you can use the ability of assertRaises to be use as a context manager and do:

with self.assertRaises(TypeError):
    self.testListNone[:1]

If you are using python2.6 another way beside the one given until now is to use unittest2 which is a back port of unittest new feature to python2.6, and you can make it work using the code above.

N.B: I'm a big fan of the new feature (SkipTest, test discovery ...) of unittest so I intend to use unittest2 as much as I can. I advise to do the same because there is a lot more than what unittest come with in python2.6 <.

Runnable is an interface defined as so:

interface Runnable {
    public void run();
}

To make a class which uses it, just define the class as (public) class MyRunnable implements Runnable {

It can be used without even making a new Thread. It's basically your basic interface with a single method, run, that can be called.

If you make a new Thread with runnable as it's parameter, it will call the run method in a new Thread.

It should also be noted that Threads implement Runnable, and that is called when the new Thread is made (in the new thread). The default implementation just calls whatever Runnable you handed in the constructor, which is why you can just do new Thread(someRunnable) without overriding Thread's run method.

I've had to do a verification of a letsencrypt certificate and I did it like this:

1. Download the root-cert and the intermediate-cert from the letsencrypt chain of trust.

2. Issue this command:

   $ openssl verify -CAfile letsencrypt-root-cert/isrgrootx1.pem.txt -untrusted letsencrypt-intermediate-cert/letsencryptauthorityx3.pem.txt /etc/letsencrypt/live/sitename.tld/cert.pem 
   /etc/letsencrypt/live/sitename.tld/cert.pem: OK
   

this should work:

for numbers, strings, date, etc.:

    public static void MyMethod(object obj)
    {
        if (typeof(IDictionary).IsAssignableFrom(obj.GetType()))
        {
            IDictionary idict = (IDictionary)obj;

            Dictionary<string, string> newDict = new Dictionary<string, string>();
            foreach (object key in idict.Keys)
            {
                newDict.Add(key.ToString(), idict[key].ToString());
            }
        }
        else
        {
            // My object is not a dictionary
        }
    }

if your dictionary also contains some other objects:

    public static void MyMethod(object obj)
    {
        if (typeof(IDictionary).IsAssignableFrom(obj.GetType()))
        {
            IDictionary idict = (IDictionary)obj;
            Dictionary<string, string> newDict = new Dictionary<string, string>();

            foreach (object key in idict.Keys)
            {
                newDict.Add(objToString(key), objToString(idict[key]));
            }
        }
        else
        {
            // My object is not a dictionary
        }
    }

    private static string objToString(object obj)
    {
        string str = "";
        if (obj.GetType().FullName == "System.String")
        {
            str = (string)obj;
        }
        else if (obj.GetType().FullName == "test.Testclass")
        {
            TestClass c = (TestClass)obj;
            str = c.Info;
        }
        return str;
    }

You need to pass --whitelisted-ips= into chrome driver (not chrome!). If you use ChromeDriver locally/directly (not using RemoteWebDriver) from code, it shouldn't be your problem.

If you use it remotely (eg. selenium hub/grid) you need to set system property when node starts, like in command:

java -Dwebdriver.chrome.whitelistedIps= testClass etc...

or docker by passing JAVA_OPTS env

  chrome:
    image: selenium/node-chrome:3.141.59
    container_name: chrome
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444
      - JAVA_OPTS=-Dwebdriver.chrome.whitelistedIps=

JSONArray may be what you want.

String message;
JSONObject json = new JSONObject();
json.put("name", "student");

JSONArray array = new JSONArray();
JSONObject item = new JSONObject();
item.put("information", "test");
item.put("id", 3);
item.put("name", "course1");
array.put(item);

json.put("course", array);

message = json.toString();

// message
// {"course":[{"id":3,"information":"test","name":"course1"}],"name":"student"}

Instead of altering the original bootstrap css class create a new css file that will override the default style.

Make sure you include the new css file after including the bootstrap.css file.

In the new css file do

.form-horizontal .control-label{
   text-align:left !important; 
}

Facebook uses a very clever technique I described in context of my scrollbar plugin jsFancyScroll:

The scrolled content is actually scrolled natively by the browser scrolling mechanisms while the native scrollbar is hidden by using overflow definitions and the custom scrollbar is kept in sync by bi-directional event listening.

Feel free to use my plugin for your project: :)

https://github.com/leoselig/jsFancyScroll/

I highly recommend it over plugins such as TinyScrollbar that come with terrible performance issues!

I was getting the exact same error for forgetting to remove the .class extension when running the JAVA class. So instead of this:

java myClass.class

One should do this:

java myClass

I explain it in-depth in this post. I'll just paste the code here with brief descriptions.

Here's the method that creates the header row. It uses the property names as column names.

private static void CreateHeader<T>(List<T> list, StreamWriter sw)
    {
        PropertyInfo[] properties = typeof(T).GetProperties();
        for (int i = 0; i < properties.Length - 1; i++)
        {
            sw.Write(properties[i].Name + ",");
        }
        var lastProp = properties[properties.Length - 1].Name;
        sw.Write(lastProp + sw.NewLine);
    }

This method creates all the value rows

private static void CreateRows<T>(List<T> list, StreamWriter sw)
    {
        foreach (var item in list)
        {
            PropertyInfo[] properties = typeof(T).GetProperties();
            for (int i = 0; i < properties.Length - 1; i++)
            {
                var prop = properties[i];
                sw.Write(prop.GetValue(item) + ",");
            }
            var lastProp = properties[properties.Length - 1];
            sw.Write(lastProp.GetValue(item) + sw.NewLine);
        }
    }

And here's the method that brings them together and creates the actual file.

public static void CreateCSV<T>(List<T> list, string filePath)
    {
        using (StreamWriter sw = new StreamWriter(filePath))
        {
            CreateHeader(list, sw);
            CreateRows(list, sw);
        }
    }

Sorry, now I've read what you expected better, so I'm updating the answer.

Based on the HTML5 Specs from W3C, nothing is wrong. I created this JSFiddle test and it's behaving correctly based on the specs (for those browsers based on the specs, like Chrome 11 and Firefox 4):

<form>_x000D_
    <input type="checkbox" name="q" id="a-0" required autofocus>_x000D_
    <label for="a-0">a-1</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-1" required>_x000D_
    <label for="a-1">a-2</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-2" required>_x000D_
    <label for="a-2">a-3</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="submit">_x000D_
</form>

I agree that it isn't very usable (in fact many people have complained about it in the W3C's mailing lists).

But browsers are just following the standard's recommendations, which is correct. The standard is a little misleading, but we can't do anything about it in practice. You can always use JavaScript for form validation, though, like some great jQuery validation plugin.

Another approach would be choosing a polyfill that can make (almost) all browsers interpret form validation rightly.

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

If you are using sakila-db from mysql website, It's very easy on the Linux platform just follow the below-mentioned steps, After downloading the zip file of sakila-db, extract it. Now you will have two files, one is sakila-schema.sql and the other one is sakila-data.sql.

1. Open terminal
2. Enter command mysql -u root -p < sakila-schema.sql
3. Enter command mysql -u root -p < sakila-data.sql
4. Now enter command mysql -u root -p and enter your password, now you have entered into mysql system with default database.
5. To use sakila database, use this command use sakila;
6. To see tables in sakila-db, use show tables command

Please take care that extracted files are present in home directory.

6. Click OK and commit the changes.

Whenever you want to get the changes from master into your work branch, do a git rebase <remote>/master. If there are any conflicts. resolve them.

When your work branch is ready, rebase again and then do git push <remote> HEAD:master. This will update the master branch on remote (central repo).

The problem for me was that my ANDROID_HOME variable was being set to another installation I forgot existed. If this is your problem, delete the old installation.

If I understand you right, we talk about a text file attachment. Thats unfortunate because if it was the email's message body, you could always use "\r\n", referring to http://www.faqs.org/rfcs/rfc822.html

But as it's an attachment, you must live with system differences. If I were in your shoes, I would choose one of those options:

a) only support windows clients by using "\r\n" as line end.

b) provide two attachment files, one with linux format and one with windows format.

c) I don't know if the attachment is to be read by people or machines, but if it is people I would consider attaching an HTML file instead of plain text. more portable and much prettier, too :)

Mcrypt PECL extenstion

 sudo apt-get -y install gcc make autoconf libc-dev pkg-config
 sudo apt-get -y install libmcrypt-dev
 sudo pecl install mcrypt-1.0.1

When you are shown the prompt

 libmcrypt prefix? [autodetect] :

Press [Enter] to autodetect.

After success installing mcrypt trought pecl, you should add mcrypt.so extension to php.ini.

The output will look like this:

...

install ok: channel://pecl.php.net/mcrypt-1.0.1
configuration option "php_ini" is not set to php.ini location
You should add "extension=mcrypt.so" to php.ini

Grab installing path and add to cli and apache2 php.ini configuration.

sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/cli/conf.d/mcrypt.ini"
sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/apache2/conf.d/mcrypt.ini"

Verify that the extension was installed

Run command:

php -i | grep "mcrypt"

The output will look like this:

A possible refinement to Thomas's excellent answer is to have Linux and possibly OSX also try to open ports and return only those which could be opened. This is because Linux, at least, lists a boatload of ports as files in /dev/ which aren't connected to anything. If you're running in a terminal, /dev/tty is the terminal in which you're working and opening and closing it can goof up your command line, so the glob is designed to not do that. Code:

    # ... Windows code unchanged ...

    elif sys.platform.startswith ('linux'):
        temp_list = glob.glob ('/dev/tty[A-Za-z]*')

    result = []
    for a_port in temp_list:

        try:
            s = serial.Serial(a_port)
            s.close()
            result.append(a_port)
        except serial.SerialException:
            pass

    return result

This modification to Thomas's code has been tested on Ubuntu 14.04 only.

I believe the Ajax response handler uses the HTTP status code to check if there was an error.

So if you just throw a Java exception on your server side code but then the HTTP response doesn't have a 500 status code jQuery (or in this case probably the XMLHttpRequest object) will just assume that everything was fine.

I'm saying this because I had a similar problem in ASP.NET where I was throwing something like a ArgumentException("Don't know what to do...") but the error handler wasn't firing.

I then set the Response.StatusCode to either 500 or 200 whether I had an error or not.

To convert from decimal to hex do...

string hexValue = decValue.ToString("X");

To convert from hex to decimal do either...

int decValue = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);

or

int decValue = Convert.ToInt32(hexValue, 16);

Set a Tag on each button to whatever you want to work with, in this case probably an Integer. Then you need only one OnClickListener for all of your buttons:

Button one = (Button) findViewById(R.id.oneButton);
Button two = (Button) findViewById(R.id.twoButton);
one.setTag(new Integer(1));
two.setTag(new Integer(2));

OnClickListener onClickListener = new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        TextView output = (TextView) findViewById(R.id.output);
        output.append(v.getTag());
    }
}

one.setOnClickListener(onClickListener);
two.setOnClickListener(onClickListener);

On newer versions of Windows (Windows 10 and Windows Server 2016) the tasks you create are located in C:\Windows\Tasks. They will have the extension .job

For example if you create the task "DoWork" it will create the task in

C:\Windows\Tasks\DoWork.job

The $(document).ready() is a jQuery event which occurs when the HTML document has been fully loaded, while the window.onload event occurs later, when everything including images on the page loaded.

Also window.onload is a pure javascript event in the DOM, while the $(document).ready() event is a method in jQuery.

$(document).ready() is usually the wrapper for jQuery to make sure the elements all loaded in to be used in jQuery...

Look at to jQuery source code to understand how it's working:

jQuery.ready.promise = function( obj ) {
    if ( !readyList ) {

        readyList = jQuery.Deferred();

        // Catch cases where $(document).ready() is called after the browser event has already occurred.
        // we once tried to use readyState "interactive" here, but it caused issues like the one
        // discovered by ChrisS here: http://bugs.jquery.com/ticket/12282#comment:15
        if ( document.readyState === "complete" ) {
            // Handle it asynchronously to allow scripts the opportunity to delay ready
            setTimeout( jQuery.ready );

        // Standards-based browsers support DOMContentLoaded
        } else if ( document.addEventListener ) {
            // Use the handy event callback
            document.addEventListener( "DOMContentLoaded", completed, false );

            // A fallback to window.onload, that will always work
            window.addEventListener( "load", completed, false );

        // If IE event model is used
        } else {
            // Ensure firing before onload, maybe late but safe also for iframes
            document.attachEvent( "onreadystatechange", completed );

            // A fallback to window.onload, that will always work
            window.attachEvent( "onload", completed );

            // If IE and not a frame
            // continually check to see if the document is ready
            var top = false;

            try {
                top = window.frameElement == null && document.documentElement;
            } catch(e) {}

            if ( top && top.doScroll ) {
                (function doScrollCheck() {
                    if ( !jQuery.isReady ) {

                        try {
                            // Use the trick by Diego Perini
                            // http://javascript.nwbox.com/IEContentLoaded/
                            top.doScroll("left");
                        } catch(e) {
                            return setTimeout( doScrollCheck, 50 );
                        }

                        // detach all dom ready events
                        detach();

                        // and execute any waiting functions
                        jQuery.ready();
                    }
                })();
            }
        }
    }
    return readyList.promise( obj );
};
jQuery.fn.ready = function( fn ) {
    // Add the callback
    jQuery.ready.promise().done( fn );

    return this;
};

Also I have created the image below as a quick references for both:

Another approach depending on how you are changing the div. If you are using JQuery to change a div's contents with its html() method, you can extend that method and call a registration function each time you put html into a div.

(function( $, oldHtmlMethod ){
    // Override the core html method in the jQuery object.
    $.fn.html = function(){
        // Execute the original HTML method using the
        // augmented arguments collection.

        var results = oldHtmlMethod.apply( this, arguments );
        com.invisibility.elements.findAndRegisterElements(this);
        return results;

    };
})( jQuery, jQuery.fn.html );

We just intercept the calls to html(), call a registration function with this, which in the context refers to the target element getting new content, then we pass on the call to the original jquery.html() function. Remember to return the results of the original html() method, because JQuery expects it for method chaining.

For more info on method overriding and extension, check out http://www.bennadel.com/blog/2009-Using-Self-Executing-Function-Arguments-To-Override-Core-jQuery-Methods.htm, which is where I cribbed the closure function. Also check out the plugins tutorial at JQuery's site.

If you want the branch to track the remote branch, which is very important if you're going to commit changes to the branch and pull changes etc, you need to add a -t for the actual checkout like so: git checkout -t branchname

If your working at a company, they may be preventing you from downloading outside software and installing it. You may need to install the plugins manually or repoint to an internal mirror repository.

In my opinion, the laziest solution (especially if you don't rely on latest bleeding edge C/C++ features, or latest compiler features) wasn't mentioned yet, so here it is:

Just build on the system with the oldest GLIBC you still want to support.

This is actually pretty easy to do nowadays with technologies like chroot, or KVM/Virtualbox, or docker, even if you don't really want to use such an old distro directly on any pc. In detail, to make a maximum portable binary of your software I recommend following these steps:

1. Just pick your poison of sandbox/virtualization/... whatever, and use it to get yourself a virtual older Ubuntu LTS and compile with the gcc/g++ it has in there by default. That automatically limits your GLIBC to the one available in that environment.

2. Avoid depending on external libs outside of foundational ones: like, you should dynamically link ground-level system stuff like glibc, libGL, libxcb/X11/wayland things, libasound/libpulseaudio, possibly GTK+ if you use that, but otherwise preferrably statically link external libs/ship them along if you can. Especially mostly self-contained libs like image loaders, multimedia decoders, etc can cause less breakage on other distros (breakage can be caused e.g. if only present somewhere in a different major version) if you statically ship them.

With that approach you get an old-GLIBC-compatible binary without any manual symbol tweaks, without doing a fully static binary (that may break for more complex programs because glibc hates that, and which may cause licensing issues for you), and without setting up any custom toolchain, any custom glibc copy, or whatever.

you can do this easily by using jquery using .css property... try this one: http://api.jquery.com/css/

Remove method will causes a lot of shift of list elements. I think is better to make a copy:

...
new_list = []
for el in obj.my_list:
   if condition_is_true(el):
      new_list.append(el)
del obj.my_list
obj.my_list = new_list
...

A shorthand answer assuming import matplotlib.pyplot as plt:

plt.gca().set_title('title')

as in:

plt.subplot(221)
plt.gca().set_title('title')
plt.subplot(222)
etc...

Then there is no need for superfluous variables.

An example of how to implement it:

public bool ValidateSocialSecNumber(string socialSecNumber)
{
    //Accepts only 10 digits, no more no less. (Like Mike's answer)
    Regex pattern = new Regex(@"(?<!\d)\d{10}(?!\d)");

    if(pattern.isMatch(socialSecNumber))
    {
        //Do something
        return true;
    }
    else
    {
        return false;
    }
}

You could've also done it in another way by e.g. using Match and then wrapping a try-catch block around the pattern matching. However, if a wrong input is given quite often, it's quite expensive to throw an exception. Thus, I prefer the above way, in simple cases at least.

I believe the async library will provide you a very elegant way to do this. While promises and callbacks can get a little hard to juggle with, async can give neat patterns to streamline your thought process. To run functions in serial, you would need to put them in an async waterfall. In async lingo, every function is called a task that takes some arguments and a callback; which is the next function in the sequence. The basic structure would look something like:

async.waterfall([
  // A list of functions
  function(callback){
      // Function no. 1 in sequence
      callback(null, arg);
  },
  function(arg, callback){
      // Function no. 2 in sequence
      callback(null);
  }
],    
function(err, results){
   // Optional final callback will get results for all prior functions
});

I've just tried to briefly explain the structure here. Read through the waterfall guide for more information, it's pretty well written.

You can use JSON.parse for that:

JSON.parse("true"); //returns boolean true

Since the introduction of go.mod , I think both local and external package management becomes easier. Using go.mod, it is possible to have go project outside the GOPATH as well.

Import local package:

Create a folder demoproject and run following command to generate go.mod file

go mod init demoproject

I have a project structure like below inside the demoproject directory.

+-- go.mod
+-- src
    +-- main.go
    +-- model
        +-- model.go

For the demo purpose, insert the following code in the model.go file.

package model

type Employee struct {
    Id          int32
    FirstName   string
    LastName    string
    BadgeNumber int32
}

In main.go, I imported Employee model by referencing to "demoproject/src/model"

package main

import (
    "demoproject/src/model"
    "fmt"
)

func main() {
    fmt.Printf("Main Function")

    var employee = model.Employee{
        Id:          1,
        FirstName:   "First name",
        LastName:    "Last Name",
        BadgeNumber: 1000,
    }
    fmt.Printf(employee.FirstName)
}

Import external dependency:

Just run go get command inside the project directory.

For example:

go get -u google.golang.org/grpc

It should include module dependency in the go.mod file

module demoproject

go 1.13

require (
    golang.org/x/net v0.0.0-20200114155413-6afb5195e5aa // indirect
    golang.org/x/sys v0.0.0-20200124204421-9fbb57f87de9 // indirect
    golang.org/x/text v0.3.2 // indirect
    google.golang.org/genproto v0.0.0-20200122232147-0452cf42e150 // indirect
    google.golang.org/grpc v1.26.0 // indirect
)

https://blog.golang.org/using-go-modules

well, i just added button in data. For Example, i should code like this:

$(target).DataTable().row.add(message).draw()

And, in message, i added button like this : [blah, blah ... "<button>Click!</button>"] and.. it works!

In Sql when any word contain @ sign it means it is variable and we use this variable to set value in it and use it on number area on the same sql script because it is only restricted on the single script while you can declare lot of variables of same type and name on many script. We use this variable in stored procedure lot because stored procedure are pre-compiled queries and we can pass values in these variable from script, desktop and websites for further information read Declare Local Variable, Sql Stored Procedure and sql injections.

Also read Protect from sql injection it will guide how you can protect your database.

Hope it help you to understand also any question comment me.

See the announcement for ASP.NET Core 3 Preview 4, which explains that this tool is no longer built-in and requires an explicit install:

The dotnet ef tool is no longer part of the .NET Core SDK

This change allows us to ship dotnet ef as a regular .NET CLI tool that can be installed as either a global or local tool. For example, to be able to manage migrations or scaffold a DbContext, install dotnet ef as a global tool typing the following command:

dotnet tool install --global dotnet-ef

To install a specific version of the tool, use the following command:

dotnet tool install --global dotnet-ef --version 3.1.4

The reason for the change is explained in the docs:

Why

This change allows us to distribute and update dotnet ef as a regular .NET CLI tool on NuGet, consistent with the fact that the EF Core 3.0 is also always distributed as a NuGet package.

In addition, you might need to add the following NuGet packages to your project:

• Microsoft.EntityFrameworkCore.SqlServer
• Microsoft.EntityFrameworkCore.Design
• Microsoft.EntityFrameworkCore.Tools

Try to change the buildToolsVersion for 23.0.2 in Gradle Script build.gradle (Module App)

then rebuild

what is the type of the field EventDate, since the ordering isn't correct i assume you don't have it set to some Date/Time representing type, but a string. And then the american way of writing dates is nasty to sort

Here's an alternative.

2. Select the Target (Gray Icon)
3. Select the Build Phases (Top Center)
4. Add Build Phase "Run Script" (Green Plus Button, bottom right)
5. In the textbox below the Shell textfield replace "Type a script or drag a script file from your workspace" with "open ${TARGET_BUILD_DIR}/${TARGET_NAME}"

This will open a terminal window with your command-line app running in it.

This is not a great solution because XCode 4 still runs and debugs the app independently of what you're doing in the terminal window that pops up.

Run package declaration and body separately.

I'm really not sure what you're doing to get that error, it looks like you're trying to run cx_Freeze on its own, without arguments. So here is a short step-by-step guide on how to do it in windows (Your screenshot looks rather like the windows command line, so I'm assuming that's your platform)

1. Write your setup.py file. Your script above looks correct so it should work, assuming that your script exists.

2. Open the command line (Start -> Run -> "cmd")

3. Go to the location of your setup.py file and run python setup.py build

Notes:

1. There may be a problem with the name of your script. "Main.py" contains upper case letters, which might cause confusion since windows' file names are not case sensitive, but python is. My approach is to always use lower case for scripts to avoid any conflicts.

2. Make sure that python is on your PATH (read http://docs.python.org/using/windows.html)1

3. Make sure are are looking at the new cx_Freeze documentation. Google often seems to bring up the old docs.

There is an internal Bash variable called $PIPESTATUS; it’s an array that holds the exit status of each command in your last foreground pipeline of commands.

<command> | tee out.txt ; test ${PIPESTATUS[0]} -eq 0

Or another alternative which also works with other shells (like zsh) would be to enable pipefail:

set -o pipefail
...

The first option does not work with zsh due to a little bit different syntax.

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

1. designate the path within the command

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

2. set the variable CMAKE_LIBRARY_PATH

   set(CMAKE_LIBRARY_PATH path1 path2)
   find_library(NAMES gtest)

the reason is as flowings:

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

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

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

The first part is answered in the FAQ as slain pointed out.

As for a workaround, you can wrap the body of the loop in a function and return early from that, e.g.

-- Print the odd numbers from 1 to 99
for a = 1, 99 do
  (function()
    if a % 2 == 0 then
      return
    end
    print(a)
  end)()
end

Or if you want both break and continue functionality, have the local function perform the test, e.g.

local a = 1
while (function()
  if a > 99 then
    return false; -- break
  end
  if a % 2 == 0 then
    return true; -- continue
  end
  print(a)
  return true; -- continue
end)() do
  a = a + 1
end

It should be

<input type="image" id="myimage" src="[...]" />

So "image" instead of "submit". It will still be a button which submits on click.

If your image is bigger than the button which is shown; let's say the image is 200x200 pixels; add this to your stylesheet:

#myimage {
    height: 200px;
    width: 200px;
}

or directly in the button tag:

<input type="image" id="myimage" style="height:200px;width:200px;" src="[...]" />

Note however that resizing the image like this might not yield ideal results; if e.g. your image is much smaller than you want it to be shown, you will see the single pixels; if on the other hand it is much bigger, you are wasting precious bandwidth of your users. So resizing the picture itself to the actual size is preferrable over rescaling via stylesheets!

You cannot add AM / PM to a TimeSpan. You'll anyway have to associate the TimaSpan value with DateTime if you want to display the time in 12-hour clock format.

TimeSpan is not intended to use with a 12-hour clock format, because we are talking about a time interval here.

As it says in the documentation;

A TimeSpan object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. The TimeSpan structure can also be used to represent the time of day, but only if the time is unrelated to a particular date. Otherwise, the DateTime or DateTimeOffset structure should be used instead.

Also Microsoft Docs describes as follows;

A TimeSpan value can be represented as [-]d.hh:mm:ss.ff, where the optional minus sign indicates a negative time interval, the d component is days, hh is hours as measured on a 24-hour clock, mm is minutes, ss is seconds, and ff is fractions of a second.

So in this case, you can display using AM/PM as follows.

TimeSpan storedTime = new TimeSpan(03,00,00);
string displayValue = new DateTime().Add(storedTime).ToString("hh:mm tt");

Side note :
Also should note that the TimeOfDay property of DateTime is a TimeSpan, where it represents

a time interval that represents the fraction of the day that has elapsed since midnight.

CORS is Cross Origin Resource Sharing, you get this error if you are trying to access from one domain to another domain.

Try using JSONP. In your case, JSONP should work fine because it only uses the GET method.

This answer will cover many of the same elements as existing answers, but this issue (passing column names to functions) comes up often enough that I wanted there to be an answer that covered things a little more comprehensively.

Suppose we have a very simple data frame:

dat <- data.frame(x = 1:4,
                  y = 5:8)

and we'd like to write a function that creates a new column z that is the sum of columns x and y.

A very common stumbling block here is that a natural (but incorrect) attempt often looks like this:

foo <- function(df,col_name,col1,col2){
      df$col_name <- df$col1 + df$col2
      df
}

#Call foo() like this:    
foo(dat,z,x,y)

The problem here is that df$col1 doesn't evaluate the expression col1. It simply looks for a column in df literally called col1. This behavior is described in ?Extract under the section "Recursive (list-like) Objects".

The simplest, and most often recommended solution is simply switch from $ to [[ and pass the function arguments as strings:

new_column1 <- function(df,col_name,col1,col2){
    #Create new column col_name as sum of col1 and col2
    df[[col_name]] <- df[[col1]] + df[[col2]]
    df
}

> new_column1(dat,"z","x","y")
  x y  z
1 1 5  6
2 2 6  8
3 3 7 10
4 4 8 12

This is often considered "best practice" since it is the method that is hardest to screw up. Passing the column names as strings is about as unambiguous as you can get.

The following two options are more advanced. Many popular packages make use of these kinds of techniques, but using them well requires more care and skill, as they can introduce subtle complexities and unanticipated points of failure. This section of Hadley's Advanced R book is an excellent reference for some of these issues.

If you really want to save the user from typing all those quotes, one option might be to convert bare, unquoted column names to strings using deparse(substitute()):

new_column2 <- function(df,col_name,col1,col2){
    col_name <- deparse(substitute(col_name))
    col1 <- deparse(substitute(col1))
    col2 <- deparse(substitute(col2))

    df[[col_name]] <- df[[col1]] + df[[col2]]
    df
}

> new_column2(dat,z,x,y)
  x y  z
1 1 5  6
2 2 6  8
3 3 7 10
4 4 8 12

This is, frankly, a bit silly probably, since we're really doing the same thing as in new_column1, just with a bunch of extra work to convert bare names to strings.

Finally, if we want to get really fancy, we might decide that rather than passing in the names of two columns to add, we'd like to be more flexible and allow for other combinations of two variables. In that case we'd likely resort to using eval() on an expression involving the two columns:

new_column3 <- function(df,col_name,expr){
    col_name <- deparse(substitute(col_name))
    df[[col_name]] <- eval(substitute(expr),df,parent.frame())
    df
}

Just for fun, I'm still using deparse(substitute()) for the name of the new column. Here, all of the following will work:

> new_column3(dat,z,x+y)
  x y  z
1 1 5  6
2 2 6  8
3 3 7 10
4 4 8 12
> new_column3(dat,z,x-y)
  x y  z
1 1 5 -4
2 2 6 -4
3 3 7 -4
4 4 8 -4
> new_column3(dat,z,x*y)
  x y  z
1 1 5  5
2 2 6 12
3 3 7 21
4 4 8 32

So the short answer is basically: pass data.frame column names as strings and use [[ to select single columns. Only start delving into eval, substitute, etc. if you really know what you're doing.

If the command should work with both tabs and spaces as the delimiter I would use awk:

awk '{print $100,$101,$102,$103,$104,$105}' myfile > outfile

As long as you just need to specify 5 fields it is imo ok to just type them, for longer ranges you can use a for loop:

awk '{for(i=100;i<=105;i++)print $i}' myfile > outfile

If you want to use cut, you need to use the -f option:

cut -f100-105 myfile > outfile

If the field delimiter is different from TAB you need to specify it using -d:

cut -d' ' -f100-105 myfile > outfile

Check the man page for more info on the cut command.

Answer in kotlin:

  context?.let {
        val displayMetrics = it.resources.displayMetrics
        val dpHeight = displayMetrics.heightPixels / displayMetrics.density
        val dpWidth = displayMetrics.widthPixels / displayMetrics.density
    }

You should avoid the usage of $.ajaxSetup() as described in the docs. Use the following instead:

$(document).ajaxSend(function(event, jqXHR, ajaxOptions) {
    jqXHR.setRequestHeader('my-custom-header', 'my-value');
});

 select * FROM doc_tab
    PIVOT
    (
    Min(document_id)
    FOR document_type IN ('Voters ID','Pan card','Drivers licence')
    ) 

outputs as this

I do not know how to solve this using code, but I do manually adjust the control panel at the right bottom in the plot figure, and adjust the figure size like:

f, ax = plt.subplots(figsize=(16, 12))

at the meantime until you get a matched size colobar. This worked for me.

You can use background-gradients for that effect. For your example just add the following lines (it is just so much code because you have to use vendor-prefixes):

background-image: 
    -moz-linear-gradient(top, #000 10px, transparent 10px),
    -moz-linear-gradient(bottom, #000 10px, transparent 10px),
    -moz-linear-gradient(left, #000 10px, transparent 10px),
    -moz-linear-gradient(right, #000 10px, transparent 10px);
background-image: 
    -o-linear-gradient(top, #000 10px, transparent 10px),
    -o-linear-gradient(bottom, #000 10px, transparent 10px),
    -o-linear-gradient(left, #000 10px, transparent 10px),
    -o-linear-gradient(right, #000 10px, transparent 10px);
background-image: 
    -webkit-linear-gradient(top, #000 10px, transparent 10px),
    -webkit-linear-gradient(bottom, #000 10px, transparent 10px),
    -webkit-linear-gradient(left, #000 10px, transparent 10px),
    -webkit-linear-gradient(right, #000 10px, transparent 10px);
background-image: 
    linear-gradient(top, #000 10px, transparent 10px),
    linear-gradient(bottom, #000 10px, transparent 10px),
    linear-gradient(left, #000 10px, transparent 10px),
    linear-gradient(right, #000 10px, transparent 10px);

No need for unecessary markup.

If you just want to have a double border you could use outline and border instead of border and padding.

While you could also use pseudo-elements to achieve the desired effect, I would advise against it. Pseudo-elements are a very mighty tool CSS provides, if you "waste" them on stuff like this, you are probably gonna miss them somewhere else.

I only use pseudo-elements if there is no other way. Not because they are bad, quite the opposite, because I don't want to waste my Joker.

1. What does $rootScope.$broadcast do?

   $rootScope.$broadcast is sending an event through the application scope. Any children scope of that app can catch it using a simple: $scope.$on().

   It is especially useful to send events when you want to reach a scope that is not a direct parent (A branch of a parent for example)

   !!! One thing to not do however is to use $rootScope.$on from a controller. $rootScope is the application, when your controller is destroyed that event listener will still exist, and when your controller will be created again, it will just pile up more event listeners. (So one broadcast will be caught multiple times). Use $scope.$on() instead, and the listeners will also get destroyed.

2. What is the difference between $rootScope.$broadcast & $rootScope.$broadcast.apply?

   Sometimes you have to use apply(), especially when working with directives and other JS libraries. However since I don't know that code base, I wouldn't be able to tell if that's the case here.

Make sure you have the access to the directory you are trying to spool. I tried to spool to root and it did not created the file (e.g c:\test.txt). You can check where you are spooling by issuing spool command.

Well, I think nginx by itself doesn't have that in its setup, because the Ubuntu-maintained package does it as a convention to imitate Debian's apache setup. You could create it yourself if you wanted to emulate the same setup.

Create /etc/nginx/sites-available and /etc/nginx/sites-enabled and then edit the http block inside /etc/nginx/nginx.conf and add this line

include /etc/nginx/sites-enabled/*;

Of course, all the files will be inside sites-available, and you'd create a symlink for them inside sites-enabled for those you want enabled.

Try This, It's working for me .

I was dealing with this issue today, and I knew that I had something encoded as a bytes object that I was trying to serialize as json with json.dump(my_json_object, write_to_file.json). my_json_object in this case was a very large json object that I had created, so I had several dicts, lists, and strings to look at to find what was still in bytes format.

The way I ended up solving it: the write_to_file.json will have everything up to the bytes object that is causing the issue.

In my particular case this was a line obtained through

for line in text:
    json_object['line'] = line.strip()

I solved by first finding this error with the help of the write_to_file.json, then by correcting it to:

for line in text:
    json_object['line'] = line.strip().decode()

Here is how to do that with the last version of HTTPClient (4.3.4)

    CloseableHttpClient httpclient = HttpClients.createDefault();
    try {
        HttpHost target = new HttpHost("localhost", 443, "https");
        HttpHost proxy = new HttpHost("127.0.0.1", 8080, "http");

        RequestConfig config = RequestConfig.custom()
                .setProxy(proxy)
                .build();
        HttpGet request = new HttpGet("/");
        request.setConfig(config);

        System.out.println("Executing request " + request.getRequestLine() + " to " + target + " via " + proxy);

        CloseableHttpResponse response = httpclient.execute(target, request);
        try {
            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            EntityUtils.consume(response.getEntity());
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }

For Netbeans 2020 September version. JDK 11

(Suggesting this for Gradle project only)

1. create libs folder in src/main/java folder of the project

2. copy past all library jars in there

3. open build.gradle in files tab of project window in project's root

4. correct main class (mine is mainClassName = 'uz.ManipulatorIkrom')

5. and in dependencies add next string:

apply plugin: 'java' 
apply plugin: 'jacoco' 
apply plugin: 'application'
description = 'testing netbeans'
mainClassName = 'uz.ManipulatorIkrom' //4th step
repositories {
    jcenter()
}
dependencies {
    implementation fileTree(dir: 'src/main/java/libs', include: '*.jar') //5th step   
}

6. save, clean-build and then run the app

Why don't you use the Modulus Operator?

Try this:

while ($s % 6 != 0) $s++;

Or is this what you meant?

<?

 $s= <some_number>;
 $k= $s % 6;

 if($k !=0)    $s=$s+6-$k;
?>

There isn't any need to pass the full path. Just use a regular expression pattern.

See --testLocationInResults.

yarn jest --testNamePattern my_test_name
yarn jest -t=auth
yarn jest -t component # This will test all whose test name contains `component`

yarn jest --testPathPattern filename # This will match the file path
yarn jest filename # This will match the file path, the same with above

t=$(mktemp) && export -p > "$t" && set -a && . ./.env && set +a && . "$t" && rm "$t" && unset t

How it works

1. Create temp file.
2. Write all current environment variables values to the temp file.
3. Enable exporting of all declared variables in the sources script to the environment.
4. Read .env file. All variables will be exported into current environment.
5. Disable exporting of all declared variables in the sources script to the environment.
6. Read the contents of the temp file. Every line would have declare -x VAR="val" that would export each of the variables into environment.
7. Remove temp file.
8. Unset the variable holding temp file name.

Features

• Preserves values of the variables already set in the environment
• .env can have comments
• .env can have empty lines
• .env does not require special header or footer like in the other answers (set -a and set +a)
• .env does not require to have export for every value
• one-liner

As to formulas being "updated" in the new row, since all the copying occurs after the shift, the old row (now one index up from the new row) has already had its formula shifted, so copying it to the new row will make the new row reference the old rows cells. A solution would be to parse out the formulas BEFORE the shift, then apply those (a simple String array would do the job. I'm sure you can code that in a few lines).

At start of function:

ArrayList<String> fArray = new ArrayList<String>();
Row origRow = sheet.getRow(sourceRow);
for (int i = 0; i < origRow.getLastCellNum(); i++) {
    if (origRow.getCell(i) != null && origRow.getCell(i).getCellType() == Cell.CELL_TYPE_FORMULA) 
        fArray.add(origRow.getCell(i).getCellFormula());
    else fArray.add(null);
}

Then when applying the formula to a cell:

newCell.setCellFormula(fArray.get(i));

you can change the size of an icon using the font size rather than setting the height and width of an icon. Here is how you do it:

<i class="fa fa-minus-square-o" style="font-size: 0.73em;"></i>

There are 4 ways to specify the dimensions of the icon.

px : give fixed pixels to your icon

em : dimensions with respect to your current font. Say ur current font is 12px then 1.5em will be 18px (12px + 6px).

pt : stands for points. Mostly used in print media

% : percentage. Refers to the size of the icon based on its original size.

Here are a couple possible solutions...

I have not tried all of these myself yet, but I will be trying them all soon.

Note: I do not have any personal or financial connection to any of these tools.

1) VB Script to EXE Converter (NOT Compiler): (Free)
vbs2exe.com.

The exe produced appears to be a true EXE.

From their website:

VBS to EXE is a free online converter that doesn't only convert your vbs files into exe but it also:

1- Encrypt your vbs file source code using 128 bit key.
2- Allows you to call win32 API
3- If you have troubles with windows vista especially when UAC is enabled then you may give VBS to EXE a try.
4- No need for wscript.exe to run your vbs anymore.
5- Your script is never saved to the hard disk like some others converters. it is a TRUE exe not an extractor.

This solution should work even if wscript/cscript is not installed on the computer.

Basically, this creates a true .EXE file. Inside the created .EXE is an "engine" that replaces wscript/cscript, and an encrypted copy of your VB Script code. This replacement engine executes your code IN MEMORY without calling wscript/cscript to do it.

2) Compile and Convert VBS to EXE...:
ExeScript

The current version is 3.5.

This is NOT a Free solution. They have a 15 day trial. After that, you need to buy a license for a hefty $44.96 (Home License/noncommercial), or $89.95 (Business License/commercial usage).

It seems to work in a similar way to the previous solution.

According to a forum post there:
Post: "A Exe file still need Windows Scripting Host (WSH) ??"

WSH is not required if "Compile" option was used, since ExeScript
implements it's own scripting host. ...

3) Encrypt the script with Microsoft's ".vbs to .vbe" encryption tool.

Apparently, this does not work for Windows 7/8, and it is possible there are ways to "decrypt" the .vbe file. At the time of writing this, I could not find a working link to download this. If I find one, I will add it to this answer.

you can use the below code to bring focus to a div, in this example the page scrolls to the <div id="navigation">

$('html, body').animate({ scrollTop: $('#navigation').offset().top }, 'slow');

I found this helpful

<?php if (strpos($_SERVER['HTTP_USER_AGENT'], 'Trident/7.0; rv:11.0') !== false) { ?>
    <script>
    $(function(){
        $('html').addClass('ie11');
    });
    </script>
<?php } ?>

If you have an array of a known type or is a subclass of Object[] you can cast the array first.

Object array = new ????[n];
Object[] array2 = (Object[]) array;
System.out.println(array2.length);

or

Object array = new char[n];
char[] array2 = (char[]) array;
System.out.println(array2.length);

However if you have no idea what type of array it is you can use Array.getLength(Object);

System.out.println(Array.getLength(new boolean[4]);
System.out.println(Array.getLength(new int[5]);
System.out.println(Array.getLength(new String[6]);

If your problem persist with all those answers, try to change the file attribute to:

File.SetAttributes(yourfile, FileAttributes.Normal);

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.

Try unmounting the overflow partition:

umount /tmp

or

umount overflow

onMeasure() is your opportunity to tell Android how big you want your custom view to be dependent the layout constraints provided by the parent; it is also your custom view's opportunity to learn what those layout constraints are (in case you want to behave differently in a match_parent situation than a wrap_content situation). These constraints are packaged up into the MeasureSpec values that are passed into the method. Here is a rough correlation of the mode values:

• EXACTLY means the layout_width or layout_height value was set to a specific value. You should probably make your view this size. This can also get triggered when match_parent is used, to set the size exactly to the parent view (this is layout dependent in the framework).
• AT_MOST typically means the layout_width or layout_height value was set to match_parent or wrap_content where a maximum size is needed (this is layout dependent in the framework), and the size of the parent dimension is the value. You should not be any larger than this size.
• UNSPECIFIED typically means the layout_width or layout_height value was set to wrap_content with no restrictions. You can be whatever size you would like. Some layouts also use this callback to figure out your desired size before determine what specs to actually pass you again in a second measure request.

The contract that exists with onMeasure() is that setMeasuredDimension() MUST be called at the end with the size you would like the view to be. This method is called by all the framework implementations, including the default implementation found in View, which is why it is safe to call super instead if that fits your use case.

Granted, because the framework does apply a default implementation, it may not be necessary for you to override this method, but you may see clipping in cases where the view space is smaller than your content if you do not, and if you lay out your custom view with wrap_content in both directions, your view may not show up at all because the framework doesn't know how large it is!

Generally, if you are overriding View and not another existing widget, it is probably a good idea to provide an implementation, even if it is as simple as something like this:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

    int desiredWidth = 100;
    int desiredHeight = 100;

Hope that Helps.

Yes you are right. You have placed WHERE clause wrong. You can only use one WHERE clause in single query so try AND for multiple conditions like this:

 SELECT table1.f_id  FROM table1 
   INNER JOIN table2
     ON table2.f_id = table1.f_id
 WHERE table2.f_type = 'InProcess'
   AND f_com_id = '430'
   AND f_status = 'Submitted' 

You can rename the file using FSO by moving it: MoveFile Method.

Dim Fso
Set Fso = WScript.CreateObject("Scripting.FileSystemObject")
Fso.MoveFile "A.txt", "B.txt"

If you're in a situation like @Keith you could try:

print(a.__dict__)

It goes against what I would consider good style but if you're just trying to debug then it should do what you want.

Yes, this is possible. One of the main pros for using Swing is the ease with which the abstract controls can be created and manipulates.

Here is a quick and dirty way to extend the existing JButton class to draw a circle to the right of the text.

package test;

import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Graphics;

import javax.swing.JButton;
import javax.swing.JFrame;

public class MyButton extends JButton {

    private static final long serialVersionUID = 1L;

    private Color circleColor = Color.BLACK;

    public MyButton(String label) {
        super(label);
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);

        Dimension originalSize = super.getPreferredSize();
        int gap = (int) (originalSize.height * 0.2);
        int x = originalSize.width + gap;
        int y = gap;
        int diameter = originalSize.height - (gap * 2);

        g.setColor(circleColor);
        g.fillOval(x, y, diameter, diameter);
    }

    @Override
    public Dimension getPreferredSize() {
        Dimension size = super.getPreferredSize();
        size.width += size.height;
        return size;
    }

    /*Test the button*/
    public static void main(String[] args) {
        MyButton button = new MyButton("Hello, World!");

        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 400);

        Container contentPane = frame.getContentPane();
        contentPane.setLayout(new FlowLayout());
        contentPane.add(button);

        frame.setVisible(true);
    }

}

Note that by overriding paintComponent that the contents of the button can be changed, but that the border is painted by the paintBorder method. The getPreferredSize method also needs to be managed in order to dynamically support changes to the content. Care needs to be taken when measuring font metrics and image dimensions.

For creating a control that you can rely on, the above code is not the correct approach. Dimensions and colours are dynamic in Swing and are dependent on the look and feel being used. Even the default Metal look has changed across JRE versions. It would be better to implement AbstractButton and conform to the guidelines set out by the Swing API. A good starting point is to look at the javax.swing.LookAndFeel and javax.swing.UIManager classes.

http://docs.oracle.com/javase/8/docs/api/javax/swing/LookAndFeel.html

http://docs.oracle.com/javase/8/docs/api/javax/swing/UIManager.html

Understanding the anatomy of LookAndFeel is useful for writing controls: Creating a Custom Look and Feel

Override Fragment.onHiddenChanged() for that.

public void onHiddenChanged(boolean hidden)

Called when the hidden state (as returned by isHidden()) of the fragment has changed. Fragments start out not hidden; this will be called whenever the fragment changes state from that.

Parameters
hidden - boolean: True if the fragment is now hidden, false if it is not visible.

For people still looking a couple of years later, things have changed a bit. You can now use the queue for .fadeIn() as well so that it will work like this:

$('.tooltip').fadeIn({queue: false, duration: 'slow'});
$('.tooltip').animate({ top: "-10px" }, 'slow');

This has the benefit of working on display: none elements so you don't need the extra two lines of code.

I'll try and answer several different things, however my contribution may not cover all of your questions. Maybe several of us can take different chunks out of this. However, this info should be helpful for you. Here we go..

Opening A Seperate File:

ChDir "[Path here]"                          'get into the right folder here
Workbooks.Open Filename:= "[Path here]"      'include the filename in this path

'copy data into current workbook or whatever you want here

ActiveWindow.Close                          'closes out the file

Opening A File With Specified Date If It Exists:

I'm not sure how to search your directory to see if a file exists, but in my case I wouldn't bother to search for it, I'd just try to open it and put in some error checking so that if it doesn't exist then display this message or do xyz.

Some common error checking statements:

On Error Resume Next   'if error occurs continues on to the next line (ignores it)

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

Or (better option):

if one doesn't exist then bring up either a message box or dialogue box to say "the file does not exist, would you like to create a new one?

you would most likely want to use the GoTo ErrorHandler shown below to achieve this

On Error GoTo ErrorHandler:

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

ErrorHandler:
'Display error message or any code you want to run on error here

Much more info on Error handling here: http://www.cpearson.com/excel/errorhandling.htm

Also if you want to learn more or need to know more generally in VBA I would recommend Siddharth Rout's site, he has lots of tutorials and example code here: http://www.siddharthrout.com/vb-dot-net-and-excel/

Hope this helps!

Example on how to ensure error code doesn't run EVERYtime:

if you debug through the code without the Exit Sub BEFORE the error handler you'll soon realize the error handler will be run everytime regarldess of if there is an error or not. The link below the code example shows a previous answer to this question.

  Sub Macro

    On Error GoTo ErrorHandler:

    ChDir "[Path here]"                         
    Workbooks.Open Filename:= "[Path here]"      'try to open file here

    Exit Sub      'Code will exit BEFORE ErrorHandler if everything goes smoothly
                  'Otherwise, on error, ErrorHandler will be run

    ErrorHandler:
    'Display error message or any code you want to run on error here

  End Sub

Also, look at this other question in you need more reference to how this works: goto block not working VBA

Late answer here, but if you search /etc/init.d/apache2 for 'reload', you'll find something like this:

do_reload() {
        if apache_conftest; then
                if ! pidofproc -p $PIDFILE "$DAEMON" > /dev/null 2>&1 ; then
                        APACHE2_INIT_MESSAGE="Apache2 is not running"
                        return 2
                fi
                $APACHE2CTL graceful > /dev/null 2>&1
                return $?
        else
                APACHE2_INIT_MESSAGE="The apache2$DIR_SUFFIX configtest failed. Not doing anything."
                return 2
        fi
}

Basically, what the answers that suggest using init.d, systemctl, etc are invoking is a thin wrapper that says:

• check the apache config
• if it's good, run apachectl graceful (swallowing the output, and forwarding the exit code)

This suggests that @Aruman's answer is also correct, provided you are confident there are no errors in your configuration or have already run apachctl configtest manually.

The apache documentation also supplies the same command for a graceful restart (apachectl -k graceful), and some more color on the behavior thereof.

It sounds like you're confused between pointers and arrays. Pointers and arrays (in this case char * and char []) are not the same thing.

• An array char a[SIZE] says that the value at the location of a is an array of length SIZE
• A pointer char *a; says that the value at the location of a is a pointer to a char. This can be combined with pointer arithmetic to behave like an array (eg, a[10] is 10 entries past wherever a points)

In memory, it looks like this (example taken from the FAQ):

 char a[] = "hello";  // array

   +---+---+---+---+---+---+
a: | h | e | l | l | o |\0 |
   +---+---+---+---+---+---+

 char *p = "world"; // pointer

   +-----+     +---+---+---+---+---+---+
p: |  *======> | w | o | r | l | d |\0 |
   +-----+     +---+---+---+---+---+---+

It's easy to be confused about the difference between pointers and arrays, because in many cases, an array reference "decays" to a pointer to it's first element. This means that in many cases (such as when passed to a function call) arrays become pointers. If you'd like to know more, this section of the C FAQ describes the differences in detail.

One major practical difference is that the compiler knows how long an array is. Using the examples above:

char a[] = "hello";  
char *p =  "world";  

sizeof(a); // 6 - one byte for each character in the string,
           // one for the '\0' terminator
sizeof(p); // whatever the size of the pointer is
           // probably 4 or 8 on most machines (depending on whether it's a 
           // 32 or 64 bit machine)

Without seeing your code, it's hard to recommend the best course of action, but I suspect changing to use pointers everywhere will solve the problems you're currently having. Take note that now:

• You will need to initialise memory wherever the arrays used to be. Eg, char a[10]; will become char *a = malloc(10 * sizeof(char));, followed by a check that a != NULL. Note that you don't actually need to say sizeof(char) in this case, because sizeof(char) is defined to be 1. I left it in for completeness.

• Anywhere you previously had sizeof(a) for array length will need to be replaced by the length of the memory you allocated (if you're using strings, you could use strlen(), which counts up to the '\0').

• You will need a make a corresponding call to free() for each call to malloc(). This tells the computer you are done using the memory you asked for with malloc(). If your pointer is a, just write free(a); at a point in the code where you know you no longer need whatever a points to.

As another answer pointed out, if you want to get the address of the start of an array, you can use:

char* p = &a[0] 

You can read this as "char pointer p becomes the address of element [0] of a".

Try specifying the actual index of the item you want erase the text from and set it's Text equal to "".

myComboBox[this.SelectedIndex].Text = ""

or

String[] stringValues= new String[hashMap.values().size()];
hashMap.values().toArray(stringValues);

Usinge the file argument in the print function, you can have different files per print:

print('Redirect output to file', file=open('/tmp/example.log', 'w'))

There are multiple ways of doing this, but if you’d prefer php, I’d recommend the use of the header() function.

Basically

$your_target_url = “www.example.com/index.php”;
header(“Location : $your_target_url”);
exit();

If you want to kick it up a notch, it’s best to use it in functions. That way, you are able to add authentications and other checking elemnts in it.

Let’s try with by checking the user’s level.

So, suppose you have stored the user’s authority level in a session called u_auth.

In the function.php

<?php
    function authRedirect($get_auth_level,
                          $required_level,
                          $if_fail_link = “www.example.com/index.php”){
        if ($get_auth_level != $required_level){
            header(location : $if_fail_link);
            return false;
            exit();
        }
        else{
            return true;
        }
     }

     . . .

You’ll then call the function for every page that you want to authenticate.

Like in page.php or any other page.

<?php

    // page.php

    require “function.php”

    // Redirects to www.example.com/index.php if the
    // user isn’t authentication level 5
    authRedirect($_SESSION[‘u_auth’], 5);

    // Redirects to www.example.com/index.php if the
    // user isn’t authentication level 4
    authRedirect($_SESSION[‘u_auth’], 4);

    // Redirects to www.someotherplace.com/somepage.php if the
    // user isn’t authentication level 2
    authRedirect($_SESSION[‘u_auth’], 2, “www.someotherplace.com/somepage.php”);

    . . .

You have to shrink & backup the log a several times to get the log file to reduce in size, this is because the the log file pages cannot be re-organized as data files pages can be, only truncated. For a more detailed explanation check this out.

Swift 3.0 solution:

let string = array.joined(separator: " ")

In Python 3.x and 2.7, you can simply do this:

>>> '${:,.2f}'.format(1234.5)
'$1,234.50'

The :, adds a comma as a thousands separator, and the .2f limits the string to two decimal places (or adds enough zeroes to get to 2 decimal places, as the case may be) at the end.

The ternary operator is a syntactic and readability convenience, not a performance shortcut. People are split on the merits of it for conditionals of varying complexity, but for short conditions, it can be useful to have a one-line expression.

Moreover, since it's an expression, as Charlie Martin wrote, that means it can appear on the right-hand side of a statement in C. This is valuable for being concise.

Unfortunately, no. This feature is not available for facebook albums.

In Kotlin you can try this way to handle getActivity() null condition.

   activity.let { // activity == getActivity() in java

        //your code here

   }

It will check activity is null or not and if not null then execute inner code.

You can use a case in this case, to separate versions one example is using FACT os (which returns the version etc of your system... the command facter will return the details:

root@sytem# facter -p os
{"name"=>"CentOS", "family"=>"RedHat", "release"=>{"major"=>"7", "minor"=>"0", "full"=>"7.0.1406"}}

#we capture release hash
$curr_os = $os['release']

case $curr_os['major'] {
  '7': { .... something }
  *: {something}
}

That is an fast example, Might have typos, or not exactly working. But using system facts you can see what happens.

The OS fact provides you 3 main variables: name, family, release... Under release you have a small dictionary with more information about your os! combining these you can create cases to meet your targets.

Apache Commons users can use ThreadUtils. The current implementation uses the walk the thread group approach previously outlined.

for (Thread t : ThreadUtils.getAllThreads()) {
      System.out.println(t.getName() + ", " + t.isDaemon());
}

Just give the Image "position: relative" and it will work

Print only current month week:

function my_week_range($date) {
    $ts = strtotime($date);
    $start = (date('w', $ts) == 0) ? $ts : strtotime('last sunday', $ts);
    echo $currentWeek = ceil((date("d",strtotime($date)) - date("w",strtotime($date)) - 1) / 7) + 1;
    $start_date = date('Y-m-d', $start);$end_date=date('Y-m-d', strtotime('next saturday', $start));
    if($currentWeek==1)
        {$start_date = date('Y-m-01', strtotime($date));}
    else if($currentWeek==5)
       {$end_date = date('Y-m-t', strtotime($date));}
    else
       {}
    return array($start_date, $end_date );
}

$date_range=list($start_date, $end_date) = my_week_range($new_fdate);

Using Ref forwarding you can pass the ref from parent to further down to a child.

const FancyButton = React.forwardRef((props, ref) => (
  <button ref={ref} className="FancyButton">
    {props.children}
  </button>
));

// You can now get a ref directly to the DOM button:
const ref = React.createRef();
<FancyButton ref={ref}>Click me!</FancyButton>;

1. Create a React ref by calling React.createRef and assign it to a ref variable.
2. Pass your ref down to by specifying it as a JSX attribute.
3. React passes the ref to the (props, ref) => ... function inside forwardRef as a second argument.
4. Forward this ref argument down to by specifying it as a JSX attribute.
5. When the ref is attached, ref.current will point to the DOM node.

Note The second ref argument only exists when you define a component with React.forwardRef call. Regular functional or class components don’t receive the ref argument, and ref is not available in props either.

Ref forwarding is not limited to DOM components. You can forward refs to class component instances, too.

Use DTO Design Pattern. It was used in EJB 2.0. Entity was container managed. DTO Design Pattern is used to solve this problem. But, it might be use now, when the application is developed Server Side and Client Side separately.DTO is used when Server side doesn't want to pass/return Entity with annotation to Client Side.

DTO Example :

PersonEntity.java

@Entity
public class PersonEntity {
    @Id
    private String id;
    private String address;

    public PersonEntity(){

    }
    public PersonEntity(String id, String address) {
        this.id = id;
        this.address = address;
    }
    //getter and setter

}

PersonDTO.java

public class PersonDTO {
    private String id;
    private String address;

    public PersonDTO() {
    }
    public PersonDTO(String id, String address) {
        this.id = id;
        this.address = address;
    }

    //getter and setter 
}

DTOBuilder.java

public class DTOBuilder() {
    public static PersonDTO buildPersonDTO(PersonEntity person) {
        return new PersonDTO(person.getId(). person.getAddress());
    }
}

EntityBuilder.java <-- it mide be need

public class EntityBuilder() {
    public static PersonEntity buildPersonEntity(PersonDTO person) {
        return new PersonEntity(person.getId(). person.getAddress());
    }
}

To convert from integers < 256 to binary, use the chr function. So you're looking at doing the following.

newFileBytes=[123,3,255,0,100]
newfile=open(path,'wb')
newfile.write((''.join(chr(i) for i in newFileBytes)).encode('charmap'))

You can enable annotation processors in IntelliJ via the following:

1. Click on File
2. Click on Settings
3. In the little search box in the upper-left hand corner, search for "Annotation Processors"
4. Check "Enable annotation processing"
5. Click OK

Assuming the list has a even number of elements, you could do:

test = [1,23,4,6,7,8]
test_rest = reversed(test[:len(test)/2])

for n in len(test_rest):
    print [test[n], test_test[n]]

It's a bit unclear what are you asking, but to make things comfortable, you can inherit your own Control and add a property with the code that Marc suggests:

class MyImage : Image {
    private Thickness thickness;
    public double MarginLeft {
        get { return Margin.Left; }
        set { thickness = Margin; thickness.Left = value; Margin = thickness; }
    }
}

Then in the client code you can write just

MyImage img = new MyImage();
img.MarginLeft = 10;
MessageBox.Show(img.Margin.Left.ToString()); // or img.MarginLeft

Combining these widgets you can create pretty usable GUIs. Of course, it's not as flexible as a toolkit integrated into a programming language, but in some cases it's really useful.

In the most basic computer science sense, recursion is a function that calls itself. Say you have a linked list structure:

struct Node {
    Node* next;
};

And you want to find out how long a linked list is you can do this with recursion:

int length(const Node* list) {
    if (!list->next) {
        return 1;
    } else {
        return 1 + length(list->next);
    }
}

(This could of course be done with a for loop as well, but is useful as an illustration of the concept)

A slightly different approach will allow you to skip GDB entirely. If all you want is a backtrace, the Linux-specific utility 'catchsegv' will catch SIGSEGV and display a backtrace.

Let me recommend mem_top tool I created

It helped me to solve a similar issue

It just instantly shows top suspects for memory leaks in a Python program

alternatively you can retrieve DOM properties with .prop

here is sample code for select box

if( ctrl.prop('type') == 'select-one' ) { // for single select }

if( ctrl.prop('type') == 'select-multiple' ) { // for multi select }

for textbox

  if( ctrl.prop('type') == 'text' ) { // for text box }

pyplot is a sub-module of matplotlib which doesn't get imported with a simple import matplotlib.

>>> import matplotlib
>>> print matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
>>> import matplotlib.pyplot
>>> 

It seems customary to do: import matplotlib.pyplot as plt at which time you can use the various functions and classes it contains:

p = plt.plot(...)

You can try to use btn-sm, btn-xs and btn-lg classes like this:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
}

JSFIDDLE DEMO

You can make use of Bootstrap .btn-group-justified css class. Or you can simply add:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
    width:50%;    //Specify your width here
}

In my case I forgot it was packaging conflict jar vs pom. I forgot to write

<packaging>pom</packaging>

In every child pom.xml file

One simple way to check your changes to that file in Tomcat 8 + is to open a browser to: http://localhost:8080/manager/text/list

Having $line as it is now, you can simply split the string based on at least one whitespace separator

my @answer = split(' ', $line); # creates an @answer array

then

print("@answer\n");               # print array on one line

or

print("$_\n") for (@answer);      # print each element on one line

I prefer using () for split, print and for.

You can do like,

int a = 3;
int b = 2;
int quotient = a / b;
int remainder = a % b;

To get quotient in real numbers

System.out.println((double) a / b);

To get quotient in integer numbers

System.out.println("Quotient: " + quotient);
System.out.println("Remainder: " + remainder);

To get quotient in real number such that one number after decimal

System.out.println(a / b + "." + a % b * 10 / b);

Note: In the last method it will not round the number up after the decimal.

Traditionally, if you only want to change the variable in your terminal windows, set it in .bashrc file, which is sourced each time a new terminal is opened. .profile file is not sourced each time you open a new terminal.

See the difference between .profile and .bashrc in question: What's the difference between .bashrc, .bash_profile, and .environment?

.bashrc should solve your problem. However, it is not the proper solution since you are using Ubuntu. See the relevant Ubuntu help page "Session-wide environment variables". Thus, no wonder that .profile does not work for you. I use Ubuntu 12.04 and xfce. I set up my .profile and it is simply not taking effect even if I log out and in. Similar experience here. So you may have to use .pam_environment file and totally forget about .profile, and .bashrc. And NOTE that .pam_environment is not a script file.

I have some general thoughts about the implementation of Task:

1. Task is disposable yet we are not supposed to use using.
2. ConfigureAwait was introduced in 4.5. Task was introduced in 4.0.
3. .NET Threads always used to flow the context (see C# via CLR book) but in the default implementation of Task.ContinueWith they do not b/c it was realised context switch is expensive and it is turned off by default.
4. The problem is a library developer should not care whether its clients need context flow or not hence it should not decide whether flow the context or not.
5. [Added later] The fact that there is no authoritative answer and proper reference and we keep fighting on this means someone has not done their job right.

I have got a few posts on the subject but my take - in addition to Tugberk's nice answer - is that you should turn all APIs asynchronous and ideally flow the context . Since you are doing async, you can simply use continuations instead of waiting so no deadlock will be cause since no wait is done in the library and you keep the flowing so the context is preserved (such as HttpContext).

Problem is when a library exposes a synchronous API but uses another asynchronous API - hence you need to use Wait()/Result in your code.

A simpler approach to this

At the beginning of column B, type

=UNIQUE(A:A)

Then in column C, use

=COUNTIF(A:A, B1)

and copy them in all row column C.

Edit: If that doesn't work for you, try using semicolon instead of comma:

=COUNTIF(A:A; B1)

Drezus - you solved it for me. Thanks so much.

In your AccountController, login should look like this:

    [AllowAnonymous]
    public ActionResult Login(string returnUrl)
    {
        ViewBag.ReturnUrl = returnUrl;
        return View();
    }

npm fund [<pkg>]

This command retrieves information on how to fund the dependencies of a given project. If no package name is provided, it will list all dependencies that are looking for funding in a tree-structure in which are listed the type of funding and the url to visit.
The message can be disabled using: npm install --no-fund

fopen() will open a resource in the same directory as the file executing the command. In other words, if you're just running the file ~/test.php, your script will create ~/myText.txt.

This can get a little confusing if you're using any URL rewriting (such as in an MVC framework) as it will likely create the new file in whatever the directory contains the root index.php file.

Also, you must have correct permissions set and may want to test before writing to the file. The following would help you debug:

$fp = fopen("myText.txt","wb");
if( $fp == false ){
    //do debugging or logging here
}else{
    fwrite($fp,$content);
    fclose($fp);
}

What I do is have a static class with the following code in my project:

    #region Dataset -> Immediate Window
public static void printTbl(DataSet myDataset)
{
    printTbl(myDataset.Tables[0]);
}
public static void printTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        Debug.Write(mytable.Columns[i].ToString() + " | ");
    }
    Debug.Write(Environment.NewLine + "=======" + Environment.NewLine);
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            Debug.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        Debug.Write(Environment.NewLine);
    }
}
public static void ResponsePrintTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        HttpContext.Current.Response.Write(mytable.Columns[i].ToString() + " | ");
    }
    HttpContext.Current.Response.Write("<BR>" + "=======" + "<BR>");
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            HttpContext.Current.Response.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        HttpContext.Current.Response.Write("<BR>");
    }
}

public static void printTblRow(DataSet myDataset, int RowNum)
{
    printTblRow(myDataset.Tables[0], RowNum);
}
public static void printTblRow(DataTable mytable, int RowNum)
{
    for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
    {
        Debug.Write(mytable.Columns[ccc].ToString() + " : ");
        Debug.Write(mytable.Rows[RowNum][ccc]);
        Debug.Write(Environment.NewLine);
    }
}
#endregion

I then I will call one of the above functions in the immediate window and the results will appear there as well. For example if I want to see the contents of a variable 'myDataset' I will call printTbl(myDataset). After hitting enter, the results will be printed to the immediate window

You could have used DISTINCT or just remove the PARTITION BY portions and use GROUP BY:

SELECT BrandId
       ,SUM(ICount)
       ,TotalICount = SUM(ICount) OVER ()    
       ,Percentage = SUM(ICount) OVER ()*1.0 / SUM(ICount) 
FROM Table 
WHERE DateId  = 20130618
GROUP BY BrandID

Not sure why you are dividing the total by the count per BrandID, if that's a mistake and you want percent of total then reverse those bits above to:

SELECT BrandId
           ,SUM(ICount)
           ,TotalICount = SUM(ICount) OVER ()    
           ,Percentage = SUM(ICount)*1.0 / SUM(ICount) OVER () 
    FROM Table 
    WHERE DateId  = 20130618
    GROUP BY BrandID

The steps mentioned by Jason are very good and should work. There is a little twist with SQL Developer, though. It caches the connection specifications (host, service name, port) the first time it reads the tnsnames.ora file. Then, it does not invalidate the specs when the original entry is removed from the tnsname.ora file. The cache persists even after SQL Developer has been terminated and restarted. This is not such an illogical way of handling the situation. Even if a tnsnames.ora file is temporarily unavailable, SQL Developer can still make the connection as long as the original specifications are still true. The problem comes with their next little twist. SQL Developer treats service names in the tnsnames.ora file as case-sensitive values when resolving the connection. So if you used to have an entry name ABCD.world in the file and you replaced it with an new entry named abcd.world, SQL Developer would NOT update its connection specs for ABCD.world - it will treat abcd.world as a different connection altogether. Why am I not surprised that an Oracle product would treat as case-sensitive the contents of an oracle-developed file format that is expressly case-insensitive?

I've used this function to merge objects in the past, I use it to add or update existing properties on obj1 with values from obj2:

var _mergeRecursive = function(obj1, obj2) {

      //iterate over all the properties in the object which is being consumed
      for (var p in obj2) {
          // Property in destination object set; update its value.
          if ( obj2.hasOwnProperty(p) && typeof obj1[p] !== "undefined" ) {
            _mergeRecursive(obj1[p], obj2[p]);

          } else {
            //We don't have that level in the heirarchy so add it
            obj1[p] = obj2[p];

          }
     }
}

It will handle multiple levels of hierarchy as well as single level objects. I used it as part of a utility library for manipulating JSON objects. You can find it here.

BalusC said:

Update: to clarify a conceptual misunderstanding, the sleep() is not required. It is just used for SSCCE/demonstration purposes. Just do your long running task right there in place of sleep().

But if you replace Thread.sleep(4000); with for (int i = 0; i < 5E8; i++) {} then it doesn't compile, because the empty loop doesn't throw an InterruptedException.

And for the thread to be interruptible, it needs to throw an InterruptedException.

This seems like a serious problem to me. I can't see how to adapt this answer to work with a general long-running task.

Edited to add: I reasked this as a new question: [ interrupting a thread after fixed time, does it have to throw InterruptedException? ]

Just use matrix:

matrix(vec,nrow = 7,ncol = 7)

One advantage of using matrix rather than simply altering the dimension attribute as Gavin points out, is that you can specify whether the matrix is filled by row or column using the byrow argument in matrix.

You can set a JavaScript variable in your WepPage that gets set once it's been loaded. You could put it anywhere, but if you're using jQuery, $(document).onReady isn't a bad place to start. If not, then you can put it in a <script> tag at the bottom of the page.

The advantage of this method as opposed to checking for element visibility is that you know the exact state of the page after the wait statement executes.

MyWebPage.html

... All my page content ...
<script> window.TestReady = true; </script></body></html>

And in your test (C# example):

// The timespan determines how long to wait for any 'condition' to return a value
// If it is exceeded an exception is thrown.
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5.0));

// Set the 'condition' as an anonymous function returning a boolean
wait.Until<Boolean>(delegate(IWebDriver d)
{
    // Check if our global variable is initialized by running a little JS
    return (Boolean)((IJavaScriptExecutor)d).ExecuteScript("return typeof(window.TestReady) !== 'undefined' && window.TestReady === true");
});

This is what The GNU C Library Reference manual says:

You can store the result of malloc into any pointer variable without a cast, because ISO C automatically converts the type void * to another type of pointer when necessary. But the cast is necessary in contexts other than assignment operators or if you might want your code to run in traditional C.

And indeed the ISO C11 standard (p347) says so:

The pointer returned if the allocation succeeds is suitably aligned so that it may be assigned to a pointer to any type of object with a fundamental alignment requirement and then used to access such an object or an array of such objects in the space allocated (until the space is explicitly deallocated)

What is Git:

"Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency"

Git is a distributed peer-peer version control system. Each node in the network is a peer, storing entire repositories which can also act as a multi-node distributed back-ups. There is no specific concept of a central server although nodes can be head-less or 'bare', taking on a role similar to the central server in centralised version control systems.

What is GitHub:

"GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features."

Github provides access control and several collaboration features such as wikis, task management, and bug tracking and feature requests for every project.

You do not need GitHub to use Git.

GitHub (and any other local, remote or hosted system) can all be peers in the same distributed versioned repositories within a single project.

Github allows you to:

• Share your repositories with others.
• Access other user's repositories.
• Store remote copies of your repositories (github servers) as backup of your local copies.

After you created a Bridging header, go to Build Setting => Search for "Objective-C Bridging Header".

Just below you will find the ""Objective-C Generated Interface Header Name" file.

Import that file in your view controller.

Example: In my case: "Dauble-Swift.h"

put it in double quotes

echo "\t";

Following on from Naresh's answer, dynamic polymorphism is only 'dynamic' in Java because of the presence of the virtual machine and its ability to interpret the code at run time rather than the code running natively.

In C++ it must be resolved at compile time if it is being compiled to a native binary using gcc, obviously; however, the runtime jump and thunk in the virtual table is still referred to as a 'lookup' or 'dynamic'. If C inherits B, and you declare B* b = new C(); b->method1();, b will be resolved by the compiler to point to a B object inside C (for a simple class inherits a class situation, the B object inside C and C will start at the same memory address so nothing is required to be done; it will be pointing at the vptr that they both use). If C inherits B and A, the virtual function table of the A object inside C entry for method1 will have a thunk which will offset the pointer to the start of the encapsulating C object and then pass it to the real A::method1() in the text segment which C has overridden. For C* c = new C(); c->method1(), c will be pointing to the outer C object already and the pointer will be passed to C::method1() in the text segment. Refer to: http://www.programmersought.com/article/2572545946/

In java, for B b = new C(); b.method1();, the virtual machine is able to dynamically check the type of the object paired with b and can pass the correct pointer and call the correct method. The extra step of the virtual machine eliminates the need for virtual function tables or the type being resolved at compile time, even when it could be known at compile time. It's just a different way of doing it which makes sense when a virtual machine is involved and code is only compiled to bytecode.

I had the same problem. My socket was eventually found in /tmp/mysql.sock. Then I added that path to php.ini. I found the socket there from checking the page "Server Status" in MySQL Workbench. If your socket isn't in /tmp/mysql.sock then maybe MySQL Workbench could tell you where it is? (Granted you use MySQL Workbench...)

Removing leading and trailing blanks might be achieved through the trim() function from the gdata package as well:

require(gdata)
example(trim)

Usage example:

> trim("   Remove leading and trailing blanks    ")
[1] "Remove leading and trailing blanks"

_{I'd prefer to add the answer as comment to user56's, but I am yet unable so writing as an independent answer.}

When you install your python version (in this case it is python2.6) then issue this command to create your virtualenv:

virtualenv -p /usr/bin/python2.6 /your/virtualenv/path/here/

I fail to see the problem with document.write. If you are using it before the onload event fires, as you presumably are, to build elements from structured data for instance, it is the appropriate tool to use. There is no performance advantage to using insertAdjacentHTML or explicitly adding nodes to the DOM after it has been built. I just tested it three different ways with an old script I once used to schedule incoming modem calls for a 24/7 service on a bank of 4 modems.

By the time it is finished this script creates over 3000 DOM nodes, mostly table cells. On a 7 year old PC running Firefox on Vista, this little exercise takes less than 2 seconds using document.write from a local 12kb source file and three 1px GIFs which are re-used about 2000 times. The page just pops into existence fully formed, ready to handle events.

Using insertAdjacentHTML is not a direct substitute as the browser closes tags which the script requires remain open, and takes twice as long to ultimately create a mangled page. Writing all the pieces to a string and then passing it to insertAdjacentHTML takes even longer, but at least you get the page as designed. Other options (like manually re-building the DOM one node at a time) are so ridiculous that I'm not even going there.

Sometimes document.write is the thing to use. The fact that it is one of the oldest methods in JavaScript is not a point against it, but a point in its favor - it is highly optimized code which does exactly what it was intended to do and has been doing since its inception.

It's nice to know that there are alternative post-load methods available, but it must be understood that these are intended for a different purpose entirely; namely modifying the DOM after it has been created and memory allocated to it. It is inherently more resource-intensive to use these methods if your script is intended to write the HTML from which the browser creates the DOM in the first place.

Just write it and let the browser and interpreter do the work. That's what they are there for.

PS: I just tested using an onload param in the body tag and even at this point the document is still open and document.write() functions as intended. Also, there is no perceivable performance difference between the various methods in the latest version of Firefox. Of course there is a ton of caching probably going on somewhere in the hardware/software stack, but that's the point really - let the machine do the work. It may make a difference on a cheap smartphone though. Cheers!

I suggest you do it a different way.

In the following code I set as a Range the column with the sports name F and loop through each cell of it, check if it is "hockey" and if yes I insert the values in the other sheet one by one, by using Offset.

I do not think it is very complicated and even if you are just learning VBA, you should probably be able to understand every step. Please let me know if you need some clarification

Sub TestThat()

'Declare the variables
Dim DataSh As Worksheet
Dim HokySh As Worksheet
Dim SportsRange As Range
Dim rCell As Range
Dim i As Long

'Set the variables
Set DataSh = ThisWorkbook.Sheets("Data")
Set HokySh = ThisWorkbook.Sheets("Hoky")

Set SportsRange = DataSh.Range(DataSh.Cells(3, 6), DataSh.Cells(Rows.Count, 6).End(xlUp))
    'I went from the cell row3/column6 (or F3) and go down until the last non empty cell

    i = 2

    For Each rCell In SportsRange 'loop through each cell in the range

        If rCell = "hockey" Then 'check if the cell is equal to "hockey"

            i = i + 1                                'Row number (+1 everytime I found another "hockey")
            HokySh.Cells(i, 2) = i - 2               'S No.
            HokySh.Cells(i, 3) = rCell.Offset(0, -1) 'School
            HokySh.Cells(i, 4) = rCell.Offset(0, -2) 'Background
            HokySh.Cells(i, 5) = rCell.Offset(0, -3) 'Age

        End If

    Next rCell

End Sub

You can use the -as operator. If casting succeed you get back a number:

$numberAsString -as [int]

Don't really know how they compare for speed, but the first one looks like the right idea for scaling to really big JSON data, since it parses only a small chunk at a time so they don't need to hold all the data in memory at once (This can be faster or slower depending on the library/use case)

You passed an argument to a function which didn't take any. For example:

It is possible to reference an intellij 'Path Variable' in an intellij 'Run Configuration'.

In 'Path Variables' create a variable for example ANALYTICS_VERSION.

In a 'Run Configuration' under 'Environment Variables' add for example the following:

ANALYTICS_LOAD_LOCATION=$MAVEN_REPOSITORY$\com\my\company\analytics\$ANALYTICS_VERSION$\bin

To answer the original question you would need to add an APP_HOME environment variable to your run configuration which references the path variable:

APP_HOME=$APP_HOME$

I agree with @CS Pei, however this didn't work for me:

split -b=1M -d file.txt file

...as the = after -b threw it off. Instead, I simply deleted it and left no space between it and the variable, and used lowercase "m":

split -b1m -d file.txt file

And to append ".txt", we use what @schoon said:

split -b=1m -d file.txt file --additional-suffix=.txt

I had a 188.5MB txt file and I used this command [but with -b5m for 5.2MB files], and it returned 35 split files all of which were txt files and 5.2MB except the last which was 5.0MB. Now, since I wanted my lines to stay whole, I wanted to split the main file every 1 million lines, but the split command didn't allow me to even do -100000 let alone "-1000000, so large numbers of lines to split will not work.

go to Start->Run type inetmgr and press OK. If you get an IIS configuration screen. It is installed, otherwise it isn't.

You can also check ControlPanel->Add Remove Programs, Click Add Remove Windows Components and look for IIS in the list of installed components.

EDIT

To Reinstall IIS.

Control Panel -> Add Remove Programs -> Click Add Remove Windows Components
Uncheck IIS box

Click next and follow prompts to UnInstall IIS. Insert your windows disc into the appropriate drive.

Control Panel -> Add Remove Programs -> Click Add Remove Windows Components
Check IIS box

Click next and follow prompts to Install IIS.

Leave you stuff there and Try the following as well:

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

If you're using Selenium with Firefox you should be able to use EXSLT extensions, and regexp:test()

Does this work for you?

String expr = "//*[regexp:test(@id, 'sometext[0-9]+_text')]";
driver.findElement(By.xpath(expr));

for some reason sharex was set to True so I turned it back to False and it worked fine.

df.plot(........,sharex=False)

Usually that problem is that in the last iteration you have an empty object or undefine object. use console.log() inside you cicle to check that this doent happend.

Sometimes a prototype in some place add an extra element.

It looks like the phoneGap plugin will allow you to get the device's uid.

http://docs.phonegap.com/en/3.0.0/cordova_device_device.md.html#device.uuid

Update: This is dependent on running native code. We used this solution writing javascript that was being compiled to native code for a native phone application we were creating.

Update for Java 8 constructs

Assuming a Book class with a name field getter, you can use Arrays.sort method by passing an additional Comparator specified using Java 8 constructs - Comparator default method & method references.

Arrays.sort(bookArray, Comparator.comparing(Book::getName));

Also, it's possible to compare on multiple fields using thenComparing methods.

Arrays.sort(bookArray, Comparator.comparing(Book::getName)
      .thenComparing(Book::getAuthor))
      .thenComparingInt(Book::getId));

tl;dr

String output = 
    LocalDate.now( ZoneId.of( "America/Montreal" ) )
             .getDayOfWeek()
             .getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH ) ;

java.time

The java.time classes built into Java 8 and later and back-ported to Java 6 & 7 and to Android include the handy DayOfWeek enum.

The days are numbered according to the standard ISO 8601 definition, 1-7 for Monday-Sunday.

DayOfWeek dow = DayOfWeek.of( 1 );

This enum includes the getDisplayName method to generate a String of the localized translated name of the day.

The Locale object specifies a human language to be used in translation, and specifies cultural norms to decide issues such as capitalization and punctuation.

String output = DayOfWeek.MONDAY.getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH ) ;

To get today’s date, use the LocalDate class. Note that a time zone is crucial as for any given moment the date varies around the globe.

ZoneId z = ZoneId.of( "America/Montreal" );
LocalDate today = LocalDate.now( z );
DayOfWeek dow = today.getDayOfWeek();
String output = dow.getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH ) ;

Keep in mind that the locale has nothing to do with the time zone.two separate distinct orthogonal issues. You might want a French presentation of a date-time zoned in India (Asia/Kolkata).

Joda-Time

UPDATE: The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

The Joda-Time library provides Locale-driven localization of date-time values.

DateTimeZone zone = DateTimeZone.forID( "America/Montreal" );
DateTime now = DateTime.now( zone );

Locale locale = Locale.CANADA_FRENCH;
DateTimeFormatter formatterUnJourQuébécois = DateTimeFormat.forPattern( "EEEE" ).withLocale( locale );

String output = formatterUnJourQuébécois.print( now );

System.out.println("output: " + output );

output: samedi

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

A more general approach:

if ( ($("body").hasClass("homepage") || $("body").hasClass("contact")) && (theLanguage == 'en-gb') )   {

       // Do something

}

people using pandas package

the following syntax to be used to import the file in python CLI

dataset(*just a variable) = pd.read_csv('new.csv')

From the spec, §15.9.1.1:

A Date object contains a Number indicating a particular instant in time to within a millisecond. Such a Number is called a time value. A time value may also be NaN, indicating that the Date object does not represent a specific instant of time.

Time is measured in ECMAScript in milliseconds since 01 January, 1970 UTC. In time values leap seconds are ignored. It is assumed that there are exactly 86,400,000 milliseconds per day. ECMAScript Number values can represent all integers from –9,007,199,254,740,992 to 9,007,199,254,740,992; this range suffices to measure times to millisecond precision for any instant that is within approximately 285,616 years, either forward or backward, from 01 January, 1970 UTC.

The actual range of times supported by ECMAScript Date objects is slightly smaller: exactly –100,000,000 days to 100,000,000 days measured relative to midnight at the beginning of 01 January, 1970 UTC. This gives a range of 8,640,000,000,000,000 milliseconds to either side of 01 January, 1970 UTC.

The exact moment of midnight at the beginning of 01 January, 1970 UTC is represented by the value +0.

The third paragraph being the most relevant. Based on that paragraph, we can get the precise earliest date per spec from new Date(-8640000000000000), which is Tuesday, April 20th, 271,821 BCE (BCE = Before Common Era, e.g., the year -271,821).

Here's the proper way to do things:

<?PHP
$sql = 'some query...';
$result = mysql_query($q);

if (! $result){
   throw new My_Db_Exception('Database error: ' . mysql_error());
}

while($row = mysql_fetch_assoc($result)){
  //handle rows.
}

Note the check on (! $result) -- if your $result is a boolean, it's certainly false, and it means there was a database error, meaning your query was probably bad.

This error message means that Windows isn't able to find "cygwin1.dll". The Programs that the Cygwin gcc create depend on this DLL. The file is part of cygwin , so most likely it's located in C:\cygwin\bin. To fix the problem all you have to do is add C:\cygwin\bin (or the location where cygwin1.dll can be found) to your system path. Alternatively you can copy cygwin1.dll into your Windows directory.

There is a nice tool called DependencyWalker that you can download from http://www.dependencywalker.com . You can use it to check dependencies of executables, so if you inspect your generated program it tells you which dependencies are missing and which are resolved.

It would be nice if there were some way of turning off "throw on non-success code" but if you catch WebException you can at least use the response:

using System;
using System.IO;
using System.Web;
using System.Net;

public class Test
{
    static void Main()
    {
        WebRequest request = WebRequest.Create("http://csharpindepth.com/asd");
        try
        {
            using (WebResponse response = request.GetResponse())
            {
                Console.WriteLine("Won't get here");
            }
        }
        catch (WebException e)
        {
            using (WebResponse response = e.Response)
            {
                HttpWebResponse httpResponse = (HttpWebResponse) response;
                Console.WriteLine("Error code: {0}", httpResponse.StatusCode);
                using (Stream data = response.GetResponseStream())
                using (var reader = new StreamReader(data))
                {
                    string text = reader.ReadToEnd();
                    Console.WriteLine(text);
                }
            }
        }
    }
}

You might like to encapsulate the "get me a response even if it's not a success code" bit in a separate method. (I'd suggest you still throw if there isn't a response, e.g. if you couldn't connect.)

If the error response may be large (which is unusual) you may want to tweak HttpWebRequest.DefaultMaximumErrorResponseLength to make sure you get the whole error.
