The header that we currently use looks like this:

---------------------------------------------------
-- Produced By   : Our company  
-- URL       : www.company.com  
-- Author        : me   
-- Date      : yesterday    
-- Purpose       : to do something  
-- Called by     : some other process   
-- Modifications : some other guy - today - to fix my bug   
------------------------------------------------------------

On a side note, any comments that I place within the SQL i always use the format:

/* Comment */

As in the past I had problems where scripting (by SQL Server) does funny things wrapping lines round and comments starting -- have commented out required SQL.... but that might just be me.

Try this for Windows:

    npm uninstall -g cordova

Try this for MAC:

    sudo npm uninstall -g cordova

You can also add Cordova like this:

1. If You Want To install the previous version of Cordova through the Node Package Manager (npm):

   npm install -g [email protected]
   

2. If You Want To install the latest version of Cordova:

   npm install -g cordova 
   

Enjoy!

I can assure you that raw speed ultimately lies in the non-standard use of Indexes for blazing speed using large tables.

Map is a part of the enumerable module. Very similar to "collect" For Example:

  Class Car

    attr_accessor :name, :model, :year

    Def initialize (make, model, year)
      @make, @model, @year = make, model, year
    end

  end

  list = []
  list << Car.new("Honda", "Accord", 2016)
  list << Car.new("Toyota", "Camry", 2015)
  list << Car.new("Nissan", "Altima", 2014)

  p list.map {|p| p.model}

Map provides values iterating through an array that are returned by the block parameters.

If you want to use one of the "Getting Started" templates from spring.io site, but you don't need any of the servlet-related stuff that comes with the "default" ("gs/spring-boot") template, you can try the scheduling-tasks template (whose pom* contains spring-boot-starter etc) instead:

https://spring.io/guides/gs/scheduling-tasks/

That gives you Spring Boot, and the app runs as a standalone (no servlets or spring-webmvc etc are included in the pom). Which is what you wanted (though you may need to add some JMS-specific stuff, as someone else points out already).

print "Python C# Test"

You will see the 'Python C# Test' in the console of C#.

In C++, there is only a subtle difference. It's a holdover from C, in which it makes a difference.

The C language standard (C89 §3.1.2.3, C99 §6.2.3, and C11 §6.2.3) mandates separate namespaces for different categories of identifiers, including tag identifiers (for struct/union/enum) and ordinary identifiers (for typedef and other identifiers).

If you just said:

struct Foo { ... };
Foo x;

you would get a compiler error, because Foo is only defined in the tag namespace.

You'd have to declare it as:

struct Foo x;

Any time you want to refer to a Foo, you'd always have to call it a struct Foo. This gets annoying fast, so you can add a typedef:

struct Foo { ... };
typedef struct Foo Foo;

Now struct Foo (in the tag namespace) and just plain Foo (in the ordinary identifier namespace) both refer to the same thing, and you can freely declare objects of type Foo without the struct keyword.

The construct:

typedef struct Foo { ... } Foo;

is just an abbreviation for the declaration and typedef.

Finally,

typedef struct { ... } Foo;

declares an anonymous structure and creates a typedef for it. Thus, with this construct, it doesn't have a name in the tag namespace, only a name in the typedef namespace. This means it also cannot be forward-declared. If you want to make a forward declaration, you have to give it a name in the tag namespace.

In C++, all struct/union/enum/class declarations act like they are implicitly typedef'ed, as long as the name is not hidden by another declaration with the same name. See Michael Burr's answer for the full details.

You must specify a delimiter for your expression. A delimiter is a special character used at the start and end of your expression to denote which part is the expression. This allows you to use modifiers and the interpreter to know which is an expression and which are modifiers. As the error message states, the delimiter cannot be a backslash because the backslash is the escape character.

$pattern = "/My name is '(.*)' and im fine/";

and below the same example but with the i modifier to match without being case sensitive.

$pattern = "/My name is '(.*)' and im fine/i";

As you can see, the i is outside of the slashes and therefore is interpreted as a modifier.

Also bear in mind that if you use a forward slash character (/) as a delimiter you must then escape further uses of / in the regular expression, if present.

A common construct is to run a loop until something is found and then to break out of the loop. The problem is that if I break out of the loop or the loop ends I need to determine which case happened. One method is to create a flag or store variable that will let me do a second test to see how the loop was exited.

For example assume that I need to search through a list and process each item until a flag item is found and then stop processing. If the flag item is missing then an exception needs to be raised.

Using the Python for...else construct you have

for i in mylist:
    if i == theflag:
        break
    process(i)
else:
    raise ValueError("List argument missing terminal flag.")

Compare this to a method that does not use this syntactic sugar:

flagfound = False
for i in mylist:
    if i == theflag:
        flagfound = True
        break
    process(i)

if not flagfound:
    raise ValueError("List argument missing terminal flag.")

In the first case the raise is bound tightly to the for loop it works with. In the second the binding is not as strong and errors may be introduced during maintenance.

You can Implement this also:- setPage(1, n); where, n = any number.

$products = Mage::getResourceModel('catalog/product_collection')
                ->addAttributeToSelect('*')
                ->addAttributeToSelect(array('name', 'price', 'small_image'))
                ->addFieldToFilter('visibility', Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH) //visible only catalog & searchable product
                ->addAttributeToFilter('status', 1) // enabled
                ->setStoreId($storeId)
                ->setOrder('created_at', 'desc')
                ->setPage(1, 6);

Let us say we have to sort a list of objects in ascending order based on a particular property, in this example lets say we have to sort based on the "name" property, then below is the required code :

var list_Objects = [{"name"="Bob"},{"name"="Jay"},{"name"="Abhi"}];
Console.log(list_Objects);   //[{"name"="Bob"},{"name"="Jay"},{"name"="Abhi"}]
    list_Objects.sort(function(a,b){
        return a["name"].localeCompare(b["name"]); 
    });
Console.log(list_Objects);  //[{"name"="Abhi"},{"name"="Bob"},{"name"="Jay"}]

same result as others, different style:

extension UIImage {

    func withAlpha(_ alpha: CGFloat) -> UIImage {
        return UIGraphicsImageRenderer(size: size).image { _ in
            draw(at: .zero, blendMode: .normal, alpha: alpha)
        }
    }

}

Try this:

@mixin heightBox($body_padding){
   height: calc(100% - $body_padding);
}

body{
   @include heightBox(100% - 25%);
   box-sizing: border-box
   padding:10px;
}

int n = 1234;
std::string nstr = std::to_string(n);
std::cout << nstr[0]; // nstr[0] -> 1

I think this is the easiest way.

We need to use std::to_string() function to convert our int to string so it will automatically create the array with our digits. We can access them simply using index - nstr[0] will show 1;

It also occurs when you try to load() an rds object instead of using

object <- readRDS("object.rds")

You are setting the extra with an array. You are then trying to get a single int.

Your code should be:

int[] arrayB = extras.getIntArray("numbers");

a good solution for this is to work with classList and contains.

i did it like this:

... for ( var i = 0; i < container.length; i++ ) {
        if ( container[i].classList.contains('half_width') ) { ...

So you need your element and check the list of the classes. If one of the classes is the same as the one you search for it will return true if not it will return false!

The question is about VS 2008 Express.

Microsoft's web page for registering Visual Studio 2008 Express has been dead (404) for some time, so registering it is not possible.

Instead, as a workaround, you can temporarily remove the requirement to register VS2008Exp by deleting (or renaming) the registry key:

HKEY_CURRENT_USER/Software/Microsoft/VCExpress/9.0/Registration

To ensure that this is working beforehand, click Help -> register product within VS2008.

You should see text like

"You have not yet registered your copy of Visual C++ 2008 Express Edition. This product will run for 10 more days before you will be required to register it."

Close the application, delete that key, reopen, click help->register product.

The text should now say

"You have not yet registered your copy of Visual C++ 2008 Express Edition. This product will run for 30 more days before you will be required to register it."

So you have two options - delete that key manually every 30 days, or run it from a batch file that also contains a line like:

reg delete HKCU\Software\Microsoft\VCExpress\9.0\Registration /f

[Edit: User @i486 confirms on testing that this workaround works even after the expiration period has expired]

[Edit2: User @Wyatt8740 has a much more elegant way to prevent the value from reappearing.]

This is a reusable variation of the solution in Mark Bracket's excellent answer.

Extension Method:

public static class ParameterExtensions
{
    public static Tuple<string, SqlParameter[]> ToParameterTuple<T>(this IEnumerable<T> values)
    {
        var createName = new Func<int, string>(index => "@value" + index.ToString());
        var paramTuples = values.Select((value, index) => 
        new Tuple<string, SqlParameter>(createName(index), new SqlParameter(createName(index), value))).ToArray();
        var inClause = string.Join(",", paramTuples.Select(t => t.Item1));
        var parameters = paramTuples.Select(t => t.Item2).ToArray();
        return new Tuple<string, SqlParameter[]>(inClause, parameters);
    }
}

Usage:

        string[] tags = {"ruby", "rails", "scruffy", "rubyonrails"};
        var paramTuple = tags.ToParameterTuple();
        var cmdText = $"SELECT * FROM Tags WHERE Name IN ({paramTuple.Item1})";

        using (var cmd = new SqlCommand(cmdText))
        {
            cmd.Parameters.AddRange(paramTuple.Item2);
        }

You don't need to send messages.

Add an event to the one form and an event handler to the other. Then you can use a third project which references the other two to attach the event handler to the event. The two DLLs don't need to reference each other for this to work.

Try this:

Create a batch file with the following:

echo off

cd\

:start

echo %time% >> c:\somedirectory\pinghostname.txt

ping pinghostname >> c:\somedirectory\pinghostname.txt

goto start

You can add your own options to the ping command based on your requirements. This doesn't put the time stamp on the same line as the ping, but it still gets you the info you need.

An even better way is to use fping, go here http://www.kwakkelflap.com/fping.html to download it.

The only difference between the two elements is semantics. Both elements, by default, have the CSS rule display: block (hence block-level) applied to them; nothing more (except somewhat extra margin in some instances). However, as aforementioned, they both different greatly in terms of semantics.

The <p> element, as its name somewhat implies, is for paragraphs. Thus, <p> should be used when you want to create blocks of paragraph text.

The <div> element, however, has little to no meaning semantically and therefore can be used as a generic block-level element — most commonly, people use it within layouts because it is meaningless semantically and can be used for generally anything you might require a block-level element for.

You can do it by specifying alternating class names on the rows. I prefer using row0 and row1, which means you can easily add them in, if the list is being built programmatically:

for ($i = 0; $i < 10; ++$i) {
    echo '<tr class="row' . ($i % 2) . '">...</tr>';
}

Another way would be to use javascript. jQuery is being used in this example:

$('table tr:odd').addClass('row1');

Edit: I don't know why I gave examples using table rows... replace tr with li and table with ul and it applies to your example

If you have a form as such:

<form id="myform">
...
</form>

You can use the following jQuery code to do something before the form is submitted:

$('#myform').submit(function() {
    // DO STUFF...
    return true; // return false to cancel form action
});

Invoke mysql with the -N (the alias for -N is --skip-column-names) option:

mysql -N ...
use testdb;
select * from names;

+------+-------+
|    1 | pete  |
|    2 | john  |
|    3 | mike  |
+------+-------+
3 rows in set (0.00 sec)

Credit to ErichBSchulz for pointing out the -N alias.

To remove the grid (the vertical and horizontal lines) around the results use -s (--silent). Columns are separated with a TAB character.

mysql -s ...
use testdb;
select * from names;

id  name
1   pete
2   john
3   mike

To output the data with no headers and no grid just use both -s and -N.

mysql -sN ...

This also works well. Is simple, lite, and doesn't require jQuery to be used.

<a href="javascript:void(0)">Link</a>

In your main.js file, you have to import Vue like this :

import Vue from 'vue'

Then you have to declare your global variable in the main.js file like this :

Vue.prototype.$actionButton = 'Not Approved'

If you want to change the value of the global variable from another component, you can do it like this :

Vue.prototype.$actionButton = 'approved'

The quick answer is 2^16 TCP ports, 64K.

The issues with system imposed limits is a configuration issue, already touched upon in previous comments.

The internal implications to TCP is not so clear (to me). Each port requires memory for it's instantiation, goes onto a list and needs network buffers for data in transit.

Given 64K TCP sessions the overhead for instances of the ports might be an issue on a 32-bit kernel, but not a 64-bit kernel (correction here gladly accepted). The lookup process with 64K sessions can slow things a bit and every packet hits the timer queues, which can also be problematic. Storage for in transit data can theoretically swell to the window size times ports (maybe 8 GByte).

The issue with connection speed (mentioned above) is probably what you are seeing. TCP generally takes time to do things. However, it is not required. A TCP connect, transact and disconnect can be done very efficiently (check to see how the TCP sessions are created and closed).

There are systems that pass tens of gigabits per second, so the packet level scaling should be OK.

There are machines with plenty of physical memory, so that looks OK.

The performance of the system, if carefully configured should be OK.

The server side of things should scale in a similar fashion.

I would be concerned about things like memory bandwidth.

Consider an experiment where you login to the local host 10,000 times. Then type a character. The entire stack through user space would be engaged on each character. The active footprint would likely exceed the data cache size. Running through lots of memory can stress the VM system. The cost of context switches could approach a second!

This is discussed in a variety of other threads: https://serverfault.com/questions/69524/im-designing-a-system-to-handle-10000-tcp-connections-per-second-what-problems

As of Ruby 2.4.0, it is easier to start an IRB REPL session in the middle of any Ruby program. Put these lines at the point in the program that you want to debug:

require 'irb'
binding.irb

You can run Ruby code and print out local variables. Type Ctrl+D or quit to end the REPL and let Ruby program keep running.

You can also use puts and p to print out values from your program as it is running.

The problem is that you are using getSystemResourceAsStream. Use simply getResourceAsStream. System resources load from the system classloader, which is almost certainly not the class loader that your jar is loaded into when run as a webapp.

It works in Eclipse because when launching an application, the system classloader is configured with your jar as part of its classpath. (E.g. java -jar my.jar will load my.jar in the system class loader.) This is not the case with web applications - application servers use complex class loading to isolate webapplications from each other and from the internals of the application server. For example, see the tomcat classloader how-to, and the diagram of the classloader hierarchy used.

EDIT: Normally, you would call getClass().getResourceAsStream() to retrieve a resource in the classpath, but as you are fetching the resource in a static initializer, you will need to explicitly name a class that is in the classloader you want to load from. The simplest approach is to use the class containing the static initializer, e.g.

[public] class MyClass {
  static
  {
    ...
    props.load(MyClass.class.getResourceAsStream("/someProps.properties"));
  }
}

This worked for me:

export function modalSave(name,id){
  console.log('modalChanges action ' + name+id);  

  return {
    type: 'EDIT',
    payload: new Promise((resolve, reject) => {
      const value = {
        Name: name,
        ID: id,
      } 

      axios({
        method: 'put',
        url: 'http://localhost:53203/api/values',
        data: value,
        config: { headers: {'Content-Type': 'multipart/form-data' }}
      })
       .then(function (response) {
         if (response.status === 200) {
           console.log("Update Success");
           resolve();
         }
       })
       .catch(function (response) {
         console.log(response);
         resolve();
       });
    })
  };
}

select ROW_NUMBER() over (order by pk_field ) as srno 
from TableName

This worked for me..

select ROW_NUMBER() over (order by column_name_of your choice ) as pri_key, the other columns of the view

Use this:

"$computer, $Speed, $Regcheck" | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

Consider using the VC++ runtime Macros for Reporting _RPTN() and _RPTFN()

You can use the _RPTn, and _RPTFn macros, defined in CRTDBG.H, to replace the use of printf statements for debugging. These macros automatically disappear in your release build when _DEBUG is not defined, so there is no need to enclose them in #ifdefs.

Example...

if (someVar > MAX_SOMEVAR) {
    _RPTF2(_CRT_WARN, "In NameOfThisFunc( )," 
         " someVar= %d, otherVar= %d\n", someVar, otherVar );
}

Or you can use the VC++ runtime functions _CrtDbgReport, _CrtDbgReportW directly.

_CrtDbgReport and _CrtDbgReportW can send the debug report to three different destinations: a debug report file, a debug monitor (the Visual Studio debugger), or a debug message window.

_CrtDbgReport and _CrtDbgReportW create the user message for the debug report by substituting the argument[n] arguments into the format string, using the same rules defined by the printf or wprintf functions. These functions then generate the debug report and determine the destination or destinations, based on the current report modes and file defined for reportType. When the report is sent to a debug message window, the filename, lineNumber, and moduleName are included in the information displayed in the window.

If you are talking about Python's actual array (available through import array from array), then the principle of least astonishment applies and you can check whether it is empty the same way you'd check if a list is empty.

from array import array
an_array = array('i') # an array of ints

if an_array:
    print("this won't be printed")

an_array.append(3)

if an_array:
    print("this will be printed")

Just to add to the other answers, I found that the simplest solution to achieve the rounded corners was to set the following as a background to your Edittext.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="@android:color/white"/>
    <corners android:radius="8dp"/>

</shape>

Java 8

LocalDate futureDate = LocalDate.now().plusMonths(1);

Put this in the manifest inside the Activity tag

  android:windowSoftInputMode="stateHidden"  

I always prefer to read input using nextLine() and then parse the string.

Using next() will only return what comes before the delimiter (defaults to whitespace). nextLine() automatically moves the scanner down after returning the current line.

A useful tool for parsing data from nextLine() would be str.split("\\s+").

String data = scanner.nextLine();
String[] pieces = data.split("\\s+");
// Parse the pieces

For more information regarding the Scanner class or String class refer to the following links.

Scanner: http://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html

String: http://docs.oracle.com/javase/7/docs/api/java/lang/String.html

# Use slicing to extract those parts of the original string to be kept
s = s[:position] + replacement + s[position+length_of_replaced:]

# Example: replace 'sat' with 'slept'
text = "The cat sat on the mat"
text = text[:8] + "slept" + text[11:]

I/P : The cat sat on the mat

O/P : The cat slept on the mat

This: "\0" is a string, not a character. A character uses single quotes, like '\0'.

In my case it was a duplicate Swift Flag entry inside my Target's Build Settings > Other Swift Flags. I had two -Xfrontend entries in it.

Nothing to do

Instead of doing a git pull, you can do:

git fetch
git reset --hard origin/master

Neither of those require you to configure your git user name / email.

This will destroy any uncommitted local changes / commits, and will leave your HEAD pointing to a commit (not a branch). But neither of those should be a problem for an app server since you shouldn't be making local changes or committing to that repository.

The standard numpy methods for calculation mean squared error (variance) and its square root (standard deviation) are numpy.var() and numpy.std(), see here and here. They apply to matrices and have the same syntax as numpy.mean().

I suppose that the question and the preceding answers might have been posted before these functions became available.

You normally use a tool like pip to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.

For this to work, you do need to install the wheel package:

pip install wheel

You can then tell pip to install the project (and it'll download the wheel if available), or the wheel file directly:

pip install project_name  # discover, download and install
pip install wheel_file.whl  # directly install the wheel

The wheel module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:

python -m wheel install wheel_file.whl

Also see the wheel project documentation.

The JPanel is actually only a container where you can put different elements in it (even other JPanels). So in your case I would suggest one big JPanel as some sort of main container for your window. That main panel you assign a Layout that suits your needs ( here is an introduction to the layouts).

After you set the layout to your main panel you can add the paint panel and the other JPanels you want (like those with the text in it..).

  JPanel mainPanel = new JPanel();
  mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));

  JPanel paintPanel = new JPanel();
  JPanel textPanel = new JPanel();

  mainPanel.add(paintPanel);
  mainPanel.add(textPanel);

This is just an example that sorts all sub panels vertically (Y-Axis). So if you want some other stuff at the bottom of your mainPanel (maybe some icons or buttons) that should be organized with another layout (like a horizontal layout), just create again a new JPanel as a container for all the other stuff and set setLayout(new BoxLayout(mainPanel, BoxLayout.X_AXIS).

As you will find out, the layouts are quite rigid and it may be difficult to find the best layout for your panels. So don't give up, read the introduction (the link above) and look at the pictures – this is how I do it :)

Or you can just use NetBeans to write your program. There you have a pretty easy visual editor (drag and drop) to create all sorts of Windows and Frames. (only understanding the code afterwards is ... tricky sometimes.)

EDIT

Since there are some many people interested in this question, I wanted to provide a complete example of how to layout a JFrame to make it look like OP wants it to.

The class is called MyFrame and extends swings JFrame

public class MyFrame extends javax.swing.JFrame{

    // these are the components we need.
    private final JSplitPane splitPane;  // split the window in top and bottom
    private final JPanel topPanel;       // container panel for the top
    private final JPanel bottomPanel;    // container panel for the bottom
    private final JScrollPane scrollPane; // makes the text scrollable
    private final JTextArea textArea;     // the text
    private final JPanel inputPanel;      // under the text a container for all the input elements
    private final JTextField textField;   // a textField for the text the user inputs
    private final JButton button;         // and a "send" button

    public MyFrame(){

        // first, lets create the containers:
        // the splitPane devides the window in two components (here: top and bottom)
        // users can then move the devider and decide how much of the top component
        // and how much of the bottom component they want to see.
        splitPane = new JSplitPane();

        topPanel = new JPanel();         // our top component
        bottomPanel = new JPanel();      // our bottom component

        // in our bottom panel we want the text area and the input components
        scrollPane = new JScrollPane();  // this scrollPane is used to make the text area scrollable
        textArea = new JTextArea();      // this text area will be put inside the scrollPane

        // the input components will be put in a separate panel
        inputPanel = new JPanel();
        textField = new JTextField();    // first the input field where the user can type his text
        button = new JButton("send");    // and a button at the right, to send the text

        // now lets define the default size of our window and its layout:
        setPreferredSize(new Dimension(400, 400));     // let's open the window with a default size of 400x400 pixels
        // the contentPane is the container that holds all our components
        getContentPane().setLayout(new GridLayout());  // the default GridLayout is like a grid with 1 column and 1 row,
        // we only add one element to the window itself
        getContentPane().add(splitPane);               // due to the GridLayout, our splitPane will now fill the whole window

        // let's configure our splitPane:
        splitPane.setOrientation(JSplitPane.VERTICAL_SPLIT);  // we want it to split the window verticaly
        splitPane.setDividerLocation(200);                    // the initial position of the divider is 200 (our window is 400 pixels high)
        splitPane.setTopComponent(topPanel);                  // at the top we want our "topPanel"
        splitPane.setBottomComponent(bottomPanel);            // and at the bottom we want our "bottomPanel"

        // our topPanel doesn't need anymore for this example. Whatever you want it to contain, you can add it here
        bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.Y_AXIS)); // BoxLayout.Y_AXIS will arrange the content vertically

        bottomPanel.add(scrollPane);                // first we add the scrollPane to the bottomPanel, so it is at the top
        scrollPane.setViewportView(textArea);       // the scrollPane should make the textArea scrollable, so we define the viewport
        bottomPanel.add(inputPanel);                // then we add the inputPanel to the bottomPanel, so it under the scrollPane / textArea

        // let's set the maximum size of the inputPanel, so it doesn't get too big when the user resizes the window
        inputPanel.setMaximumSize(new Dimension(Integer.MAX_VALUE, 75));     // we set the max height to 75 and the max width to (almost) unlimited
        inputPanel.setLayout(new BoxLayout(inputPanel, BoxLayout.X_AXIS));   // X_Axis will arrange the content horizontally

        inputPanel.add(textField);        // left will be the textField
        inputPanel.add(button);           // and right the "send" button

        pack();   // calling pack() at the end, will ensure that every layout and size we just defined gets applied before the stuff becomes visible
    }

    public static void main(String args[]){
        EventQueue.invokeLater(new Runnable(){
            @Override
            public void run(){
                new MyFrame().setVisible(true);
            }
        });
    }
}

Please be aware that this is only an example and there are multiple approaches to layout a window. It all depends on your needs and if you want the content to be resizable / responsive. Another really good approach would be the GridBagLayout which can handle quite complex layouting, but which is also quite complex to learn.

I found this to be a good solution for the most part:

SELECT * FROM table ORDER BY ISNULL(field), field ASC;

You can easily launch Firefox from the command line with a proxy server using the -proxy-server option.

This works on Mac, Windows and Linux.

path_to_firefox/firefox.exe -proxy-server %proxy_URL%

Mac Example:

/Applications/Firefox.app/Contents/MacOS/firefox -proxy-server proxy.example.com

For this purpose and if i dont have boolean variable i use the following:

<li th:class="${#strings.contains(content.language,'CZ')} ? active : ''">

As you mentioned in a comment, you're using log4j. I discovered (inadvertently) a place where I had written

LOG.error(exc);

instead of the typical

LOG.error("Some informative message", e);

through laziness or perhaps just not thinking about it. The unfortunate part of this is that it doesn't behave as you expect. The logger API actually takes Object as the first argument, not a string - and then it calls toString() on the argument. So instead of getting the nice pretty stack trace, it just prints out the toString - which in the case of NPE is pretty useless.

Perhaps this is what you're experiencing?

I think you need something like this....

b="HELLO,THERE,WORLD"
re.findall('[\w]+',b)

Which in Python3 will return

['HELLO', 'THERE', 'WORLD']

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

Getting the latest Code

$ git pull <remote> <branch> # fetches the code and merges it into 
                             # your working directory
$ git fetch <remote> <branch> # fetches the code but does not merge
                              # it into your working directory

$ git pull --tag <remote> <branch> # same as above but fetch tags as well
$ git fetch --tag <remote> <branch> # you get the idea

That pretty much covers every case for getting the latest copy of the code from the remote repository.

To convert UTC time to Local you have to use moment.local().

For more info see docs

Example:

var date = moment.utc().format('YYYY-MM-DD HH:mm:ss');

console.log(date); // 2015-09-13 03:39:27

var stillUtc = moment.utc(date).toDate();
var local = moment(stillUtc).local().format('YYYY-MM-DD HH:mm:ss');

console.log(local); // 2015-09-13 09:39:27

Demo:

var date = moment.utc().format();_x000D_
console.log(date, "- now in UTC"); _x000D_
_x000D_
var local = moment.utc(date).local().format();_x000D_
console.log(local, "- UTC now to local");

public class SwitchTest {
    public static void main(String[] args){
        for(int i = 0;i<10;i++){
            switch(i){
                case 1: case 2: case 3: case 4: //First case
                    System.out.println("First case");
                    break;
                case 8: case 9: //Second case
                    System.out.println("Second case");
                    break;
                default: //Default case
                    System.out.println("Default case");
                    break;
            }
        }
    }
}

Out:

Default case
First case
First case

Use round()

$float_val = 4.5;

echo round($float_val);

You can also set param for precision and rounding mode, for more info

Update (According to your updated question):

$float_val = 1.0000124668092E+14;
printf('%.0f', $float_val / 1E+14); //Output Rounds Of To 1000012466809201

From the Help:
IsEmpty returns True if the variable is uninitialized, or is explicitly set to Empty; otherwise, it returns False. False is always returned if expression contains more than one variable.
IsEmpty only returns meaningful information for variants.

To check if a cell is empty, you can use cell(x,y) = "".
You might eventually save time by using Range("X:Y").SpecialCells(xlCellTypeBlanks) or xlCellTypeConstants or xlCellTypeFormulas

Use option bty = "n" in legend to remove the box around the legend. For example:

legend(1, 5,
       "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",
       bty = "n")

I have used the below code in my existing project

<div class="form-group" [ngStyle]="{'border':isSubmitted && form_data.controls.first_name.errors?'1px solid red':'' }">
</div>

You can redirect forward or mask your domain name in godaddy but I don't know about other hosting sites.Have a look on this link

You're getting None because list.sort() it operates in-place, meaning that it doesn't return anything, but modifies the list itself. You only need to call a.sort() without assigning it to a again.

There is a built in function sorted(), which returns a sorted version of the list - a = sorted(a) will do what you want as well.

Edit:

There's either a bug with git pull, or you can't do what you're trying to do with that command. You can however, do it with fetch and merge:

cd /X
git --git-dir=/X/Y/.git fetch
git --git-dir=/X/Y/.git --work-tree=/X/Y merge origin/master

Original answer:

Assuming you're running bash or similar, you can do (cd /X/Y; git pull).

The git man page specifies some variables (see "The git Repository") that seem like they should help, but I can't make them work right (with my repository in /tmp/ggg2):

GIT_WORK_TREE=/tmp/ggg2 GIT_DIR=/tmp/ggg2/.git git pull
fatal: /usr/lib/git-core/git-pull cannot be used without a working tree.

Running the command below while my cwd is /tmp updates that repo, but the updated file appears in /tmp instead of the working tree /tmp/ggg2:

GIT_DIR=/tmp/ggg2/.git git pull

See also this answer to a similar question, which demonstrates the --git-dir and --work-tree flags.

In case you want to compare strings, write the following JSTL :

<c:choose>
    <c:when test="${myvar.equals('foo')}">
        ...
    </c:when>
    <c:when test="${myvar.equals('bar')}">
        ...
    </c:when>
    <c:otherwise>
        ...
    </c:otherwise>
</c:choose>

You can also dynamically create a class by using DynamicExpressions.

Since 'Dictionary's have compact initializers and handle key collisions, you will want to do something like this.

  var list = new Dictionary<string, string> {
    {
      "EmployeeID",
      "int"
    }, {
      "EmployeeName",
      "String"
    }, {
      "Birthday",
      "DateTime"
    }
  };

Or you might want to use a JSON converter to construct your serialized string object into something manageable.

Then using System.Linq.Dynamic;

  IEnumerable<DynamicProperty> props = list.Select(property => new DynamicProperty(property.Key, Type.GetType(property.Value))).ToList();

  Type t = DynamicExpression.CreateClass(props);

The rest is just using System.Reflection.

  object obj = Activator.CreateInstance(t);
  t.GetProperty("EmployeeID").SetValue(obj, 34, null);
  t.GetProperty("EmployeeName").SetValue(obj, "Albert", null);
  t.GetProperty("Birthday").SetValue(obj, new DateTime(1976, 3, 14), null);
}  

df.tail(1).index 

seems the most readable

{glue} offers much better string interpolation, see my other answer. Also, as Dainis rightfully mentions, sprintf() is not without problems.

There's also sprintf():

sprintf("Current working dir: %s", wd)

To print to the console output, use cat() or message():

cat(sprintf("Current working dir: %s\n", wd))
message(sprintf("Current working dir: %s\n", wd))

This the quick way to change HTML tags inside your DOM using jQuery. I find this replaceWith() function is very useful.

   var text= $('p').text();
   $('#change').on('click', function() {
     target.replaceWith( "<h5>"+text+"</h5>" );
   });

I wrote this simple function just pass req.headers.cookie and cookie name

const getCookieByName =(cookies,name)=>{
    const arrOfCookies = cookies.split(' ')
    let yourCookie = null

    arrOfCookies.forEach(element => {
        if(element.includes(name)){
            yourCookie = element.replace(name+'=','')
        }
    });
    return yourCookie
}

Try this one:

Color color = new Color (10,10,10)


myPaint.setColor(color.getRGB());

Here's the simplest solution (Jibwa made it seem complicated in another answer), without having to generate indices yourself - just using the ShuffleSplit object to generate 1 split.

import numpy as np 
from sklearn.model_selection import ShuffleSplit # or StratifiedShuffleSplit
sss = ShuffleSplit(n_splits=1, test_size=0.1)

data_size = 100
X = np.reshape(np.random.rand(data_size*2),(data_size,2))
y = np.random.randint(2, size=data_size)

sss.get_n_splits(X, y)
train_index, test_index = next(sss.split(X, y)) 

X_train, X_test = X[train_index], X[test_index] 
y_train, y_test = y[train_index], y[test_index]

You need to include inttypes.h if you want all those nifty new format specifiers for the intN_t types and their brethren, and that is the correct (ie, portable) way to do it, provided your compiler complies with C99. You shouldn't use the standard ones like %d or %u in case the sizes are different to what you think.

It includes stdint.h and extends it with quite a few other things, such as the macros that can be used for the printf/scanf family of calls. This is covered in section 7.8 of the ISO C99 standard.

For example, the following program:

#include <stdio.h>
#include <inttypes.h>
int main (void) {
    uint32_t a=1234;
    uint16_t b=5678;
    printf("%" PRIu32 "\n",a);
    printf("%" PRIu16 "\n",b);
    return 0;
}

outputs:

1234
5678

I really like the description and the example from http://python-3-patterns-idioms-test.readthedocs.io/en/latest/Visitor.html.

The assumption is that you have a primary class hierarchy that is fixed; perhaps it’s from another vendor and you can’t make changes to that hierarchy. However, your intent is that you’d like to add new polymorphic methods to that hierarchy, which means that normally you’d have to add something to the base class interface. So the dilemma is that you need to add methods to the base class, but you can’t touch the base class. How do you get around this?

The design pattern that solves this kind of problem is called a “visitor” (the final one in the Design Patterns book), and it builds on the double dispatching scheme shown in the last section.

The visitor pattern allows you to extend the interface of the primary type by creating a separate class hierarchy of type Visitor to virtualize the operations performed upon the primary type. The objects of the primary type simply “accept” the visitor, then call the visitor’s dynamically-bound member function.

LPCWSTR stands for "Long Pointer to Constant Wide String". The W stands for Wide and means that the string is stored in a 2 byte character vs. the normal char. Common for any C/C++ code that has to deal with non-ASCII only strings.=

To get a normal C literal string to assign to a LPCWSTR, you need to prefix it with L

LPCWSTR a = L"TestWindow";

A good place to start is the sample application provided on the developer docs.

• Guidelines would be to just make it as usable as possible. Take a look at the others available on the market to see what you should be aiming for
• Yes, services can do most things, including internet; provided you have asked for those permissions
• You can open activities and do anything you like n those if you run into a problem with doing some things in the keyboard. For example HTC's keyboard has a button to open the settings activity, and another to open a dialog to change languages.

Take a look at other IME's to see what you should be aiming for. Some (like the official one) are open source.

Just for fun, I found an interesting article here, to use a somehow hidden evaluate function that does exist in Excel. The trick is to assign it to a name, and use the name in your cells, because EVALUATE() would give you an error msg if used directly in a cell. I tried and it works! You can use it with a relative name, if you want to copy accross rows if a sheet.

List<string> keyList = new List<string>(this.yourDictionary.Keys);

Ok - my case was not strictly related to this question, but I ended up on this page when Googling for the same exception; I queried an SQL database with LINQ when I got this exception.

private Table<SubscriptionModel> m_subscriptionsSql;
var query = from SubscriptionModel subscription in m_subscriptionsSql ...

Turned out I forgot to initialize my Table instance variable, that I used in the LINQ query.

m_subscriptionsSql = GetTable<SubscriptionModel>();

User-specific settings should be written to HKCU\Software, machine-specific settings to HKLM\Software. Under these keys, structure [software vendor name]\[application name] (e.g. HKLM\Software\Microsoft\Internet Explorer) may be the most common, but that's just a convention, not a law of nature.

Many (most?) applications also add their uninstall entries to HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\[app name], but again, not all applications do this.

These are the most important keys; however, contents of the registry do not have to represent the installed software exactly - maybe the application was installed once, but then was manually deleted, or maybe the uninstaller didn't remove all traces of it. If you want to be sure, check the filesystem to see if the application still exists where its registry entries say it is.

Edit:

If you're a member of the group Administrators, you can check the HKEY_USERS hive - each user's HKCU actually resides there (you'll need to know the user SID, or go through all of them).

Note: As @Brian Ensink says, "installed" is a bit of a vague concept - are we trying to find what the user could run? Some software doesn't even write to the Registry at all: search for "portable apps" to see apps that have been specifically modified to run directly from media (CD/USB) and not to leave any traces on the computer. We may also have to scan the disks, and network disks, and anything the user downloads, and world-accessible Windows shares in the Internet (yes, such things exist legitimately - \\live.sysinternals.com\tools comes to mind). In this direction, there's no real limit of what the user can run, unless prevented by system policies.

If you're using Entity Framework, exception.ToString() will not gives you the details of DbEntityValidationException exceptions. You might want to use the same method to handle all your exception, like:

catch (Exception ex)
{
   Log.Error(GetExceptionDetails(ex));
}

Where GetExceptionDetails contains something like this:

public static string GetExceptionDetails(Exception ex)
{
    var stringBuilder = new StringBuilder();

    while (ex != null)
    {
        switch (ex)
        {
            case DbEntityValidationException dbEx:
                var errorMessages = dbEx.EntityValidationErrors.SelectMany(x => x.ValidationErrors).Select(x => x.ErrorMessage);
                var fullErrorMessage = string.Join("; ", errorMessages);
                var message = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);

                stringBuilder.Insert(0, dbEx.StackTrace);
                stringBuilder.Insert(0, message);
                break;

            default:
                stringBuilder.Insert(0, ex.StackTrace);
                stringBuilder.Insert(0, ex.Message);
                break;
        }

        ex = ex.InnerException;
    }

    return stringBuilder.ToString();
}

Justin's answer is probably the way to go, although in some applications it might make sense to consider a particular search as a resource in its own right, such as if you want to support named saved searches:

/search/{searchQuery}

or

/search/{savedSearchName}

We had been getting similar error messages while processing an Analysis Services database. It turned out that the username, which was used to run the Analysis Services instance, had not been added to the SQL Server's Security Logins.

In SQL Server 2012, the SQL Server and Analysis services are configured to run as different users by default. If you have gone with the defaults, always ensure that the AS user has access to your datasource!

For those using Laravel, this https://github.com/sitepoint-editors/google-laravel-2FA is a nice way to solve this problem.

Importing Jobs Manually: Alternate way

Upload the Jobs on to Git (Version Control) Basically upload config.xml of the Job.

If Linux Servers:

cd /var/lib/jenkins/jobs/<Job name> 
Download the config.xml from Git

Restart the Jenkins

Methods can only declare local variables. That is why the compiler reports an error when you try to declare it as public.

In the case of local variables you can not use any kind of accessor (public, protected or private).

You should also know what the static keyword means. In method checkYourself, you use the Integer array locations.

The static keyword distinct the elements that are accessible with object creation. Therefore they are not part of the object itself.

public class Test { //Capitalized name for classes are used in Java
   private final init[] locations; //key final mean that, is must be assigned before object is constructed and can not be changed later. 

   public Test(int[] locations) {
      this.locations = locations;//To access to class member, when method argument has the same name use `this` key word. 
   }

   public boolean checkYourSelf(int value) { //This method is accessed only from a object.
      for(int location : locations) {
         if(location == value) {
            return true; //When you use key word return insied of loop you exit from it. In this case you exit also from whole method.
         }
      }
      return false; //Method should be simple and perform one task. So you can get more flexibility. 
   }
   public static int[] locations = {1,2,3};//This is static array that is not part of object, but can be used in it. 

   public static void main(String[] args) { //This is declaration of public method that is not part of create object. It can be accessed from every place.
      Test test = new Test(Test.locations); //We declare variable test, and create new instance (object) of class Test.  
      String result;
      if(test.checkYourSelf(2)) {//We moved outside the string
        result = "Hurray";        
      } else {
        result = "Try again"
      }
      System.out.println(result); //We have only one place where write is done. Easy to change in future.
   } 
}

Use this function to get the client MAC address:

function GetClientMac(){
    $macAddr=false;
    $arp=`arp -n`;
    $lines=explode("\n", $arp);

    foreach($lines as $line){
        $cols=preg_split('/\s+/', trim($line));

        if ($cols[0]==$_SERVER['REMOTE_ADDR']){
            $macAddr=$cols[2];
        }
    }

    return $macAddr;
}

2 ways to work around this:

for ' you can simply double it in the string, e.g. select 'I''m happpy' -- will get: I'm happy

For any charactor you are not sure of: in sql server you can get any char's unicode by select unicode(':') (you keep the number)

So this case you can also select 'I'+nchar(39)+'m happpy'

Use SimpleDateFormat to format any Date object you want:

TimeZone tz = TimeZone.getTimeZone("UTC");
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm'Z'"); // Quoted "Z" to indicate UTC, no timezone offset
df.setTimeZone(tz);
String nowAsISO = df.format(new Date());

Using a new Date() as shown above will format the current time.

input[type="text"]
{
    background: transparent;
    border: none;
}

Nobody will even know it's there.

Here I get only three specific columns from mainDataTable and use the filter

DataTable checkedParams = mainDataTable.Select("checked = true").CopyToDataTable()
.DefaultView.ToTable(false, "lagerID", "reservePeriod", "discount");

Internet Control Message Protocol

http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol

ICMP is built on top of a bunch of other protocols, so in that sense your TA is correct. However, ping itself is ICMP.

This is my solution:

function resolve(path, obj) {
    return path.split('.').reduce(function(prev, curr) {
        return prev ? prev[curr] : null
    }, obj || self)
}

Usage examples:

resolve("document.body.style.width")
// or
resolve("style.width", document.body)
// or even use array indexes
// (someObject has been defined in the question)
resolve("part.0.size", someObject) 
// returns null when intermediate properties are not defined:
resolve('properties.that.do.not.exist', {hello:'world'})

Len won't yield the total number of objects in a nested list (including multidimensional lists). If you have numpy, use size(). Otherwise use list comprehensions within recursion.

Just to complete JJC answer, in python 3.5.3 the behavior is correct if you use hashlib this way:

$ python3 -c '
import hashlib
hash_object = hashlib.sha256(b"Caroline")
hex_dig = hash_object.hexdigest()
print(hex_dig)
'
739061d73d65dcdeb755aa28da4fea16a02b9c99b4c2735f2ebfa016f3e7fded
$ python3 -c '
import hashlib
hash_object = hashlib.sha256(b"Caroline")
hex_dig = hash_object.hexdigest()
print(hex_dig)
'
739061d73d65dcdeb755aa28da4fea16a02b9c99b4c2735f2ebfa016f3e7fded

$ python3 -V
Python 3.5.3

You can pass PHP Variables to your JavaScript by generating it with PHP:

<?php
$someVar = 1;
?>

<script type="text/javascript">
    var javaScriptVar = "<?php echo $someVar; ?>";
</script>

ok I finally found a good solution:

$('iframe').load(function() {
    this.style.height =
    this.contentWindow.document.body.offsetHeight + 'px';
});

Because some browsers (older Safari and Opera) report onload completed before CSS renders you need to set a micro Timeout and blank out and reassign the iframe's src.

$('iframe').load(function() {
    setTimeout(iResize, 50);
    // Safari and Opera need a kick-start.
    var iSource = document.getElementById('your-iframe-id').src;
    document.getElementById('your-iframe-id').src = '';
    document.getElementById('your-iframe-id').src = iSource;
});
function iResize() {
    document.getElementById('your-iframe-id').style.height = 
    document.getElementById('your-iframe-id').contentWindow.document.body.offsetHeight + 'px';
}

In the Window menu, open Show View -> Other ... and type log to find it.

Since IPv4 addresses are 4 byte long, you could use an INT (UNSIGNED) that has exactly 4 bytes:

`ipv4` INT UNSIGNED

And INET_ATON and INET_NTOA to convert them:

INSERT INTO `table` (`ipv4`) VALUES (INET_ATON("127.0.0.1"));
SELECT INET_NTOA(`ipv4`) FROM `table`;

For IPv6 addresses you could use a BINARY instead:

`ipv6` BINARY(16)

And use PHP’s inet_pton and inet_ntop for conversion:

'INSERT INTO `table` (`ipv6`) VALUES ("'.mysqli_real_escape_string(inet_pton('2001:4860:a005::68')).'")'
'SELECT `ipv6` FROM `table`'
$ipv6 = inet_pton($row['ipv6']);

I've had same problem, when I was installed MS WebMatrix, IIS Server was blocked the port 80 which XAMPP was running on. I tried to find World Wide Web Publishing Service and stop it, but could not find it on list. Best way is changing a port.

Please refer with this
link ref.

in smarty V3 you can use this

{var_dump($variable)}

Please see the comments.

Code:

import subprocess


class MyLibrary(object):

    def execute(self, cmd):
        return subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, universal_newlines=True,)
      
    def list(self):
        command = ["ping", "google.com"]
        sp = self.execute(command)
        status = sp.wait()  # will wait for sp to finish
        out, err = sp.communicate()
        print(out)
        return status # 0 is success else error


test = MyLibrary()

print(test.list())

Output:

You may want to consider using a different type of loop where that logic is applicable, because it is the most obvious answer.

perhaps a:

i=2
while i < n:
    if something:
       do something
       i += 1
    else: 
       do something else  
       i = 2 #restart the loop  

It did not worked for me until i created:

#created cc string
cc = ""[email protected];
#added cc to header
msg['Cc'] = cc

and than added cc in recipient [list] like:

s.sendmail(me, [you,cc], msg.as_string())

Try this

<input onclick="confirmSubmit(event);" type="button" value="Send" />

Along with this

function confirmSubmit(event){
            var domElement =$(event.target);
            console.log(domElement.attr('type'));
        }

I tried it in firefox, it prints the 'type' attribute of dom Element clicked. I guess you can then get the form via the parents() methods using this object.

When you download the connector/NET choose Select Platform = .NET & Mono (not windows!)

Inconsolata (http://www.levien.com/type/myfonts/inconsolata.html) is a great monospaced font for programming. Earlier versions tend to act weird on OS X, but the newer versions work out very well.

One of the first differences that I can recall from top of my head are multiple domains running in the same server, partial resource retrieval, this allows you to retrieve and speed up the download of a resource (it's what almost every download accelerator does).

If you want to develop an application like a website or similar, you don't need to worry too much about the differences but you should know the difference between GET and POST verbs at least.

Now if you want to develop a browser then yes, you will have to know the complete protocol as well as if you are trying to develop a HTTP server.

If you are only interested in knowing the HTTP protocol I would recommend you starting with HTTP/1.1 instead of 1.0.

Example:

int x = Convert.ToInt32(this.txtboxname.Text) + 1 //You dont need the "this"
txtboxname.Text = x.ToString();

The x.ToString() makes the integer into string to show that in the text box.

Result:

1. You put number in the text box.
2. You click on the button or something running the function.
3. You see your number just bigger than your number by one in your text box.

:)

I've searched solution to similar problem and maybe my way will help You and anybody who face with it.

I used SelectedValuePath="id" in XAML DataGrid definition, and programaticaly only thing I have to do is set DataGrid.SelectedValue to desired value.

I know this solution has pros and cons, but in specific case is fast and easy.

For INNER joins, no, the order doesn't matter. The queries will return same results, as long as you change your selects from SELECT * to SELECT a.*, b.*, c.*.

For (LEFT, RIGHT or FULL) OUTER joins, yes, the order matters - and (updated) things are much more complicated.

First, outer joins are not commutative, so a LEFT JOIN b is not the same as b LEFT JOIN a

Outer joins are not associative either, so in your examples which involve both (commutativity and associativity) properties:

a LEFT JOIN b 
    ON b.ab_id = a.ab_id
  LEFT JOIN c
    ON c.ac_id = a.ac_id

is equivalent to:

a LEFT JOIN c 
    ON c.ac_id = a.ac_id
  LEFT JOIN b
    ON b.ab_id = a.ab_id

but:

a LEFT JOIN b 
    ON  b.ab_id = a.ab_id
  LEFT JOIN c
    ON  c.ac_id = a.ac_id
    AND c.bc_id = b.bc_id

is not equivalent to:

a LEFT JOIN c 
    ON  c.ac_id = a.ac_id
  LEFT JOIN b
    ON  b.ab_id = a.ab_id
    AND b.bc_id = c.bc_id

Another (hopefully simpler) associativity example. Think of this as (a LEFT JOIN b) LEFT JOIN c:

a LEFT JOIN b 
    ON b.ab_id = a.ab_id          -- AB condition
 LEFT JOIN c
    ON c.bc_id = b.bc_id          -- BC condition

This is equivalent to a LEFT JOIN (b LEFT JOIN c):

a LEFT JOIN  
    b LEFT JOIN c
        ON c.bc_id = b.bc_id          -- BC condition
    ON b.ab_id = a.ab_id          -- AB condition

only because we have "nice" ON conditions. Both ON b.ab_id = a.ab_id and c.bc_id = b.bc_id are equality checks and do not involve NULL comparisons.

You can even have conditions with other operators or more complex ones like: ON a.x <= b.x or ON a.x = 7 or ON a.x LIKE b.x or ON (a.x, a.y) = (b.x, b.y) and the two queries would still be equivalent.

If however, any of these involved IS NULL or a function that is related to nulls like COALESCE(), for example if the condition was b.ab_id IS NULL, then the two queries would not be equivalent.

I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.

Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.

Here is an attempt at this with your data:

import matplotlib.pyplot as plt

# ... define 2D array hist as you did

plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case

Here is the solution :

@media (min-width: 1200px) {
    .container{
        max-width: 970px;
    }
}

The advantage of doing this, versus customizing Bootstrap as in @Bastardo's answer, is that it doesn't change the Bootstrap file. For example, if using a CDN, you can still download most of Bootstrap from the CDN.

None of these solutions worked for me inside a Weebly "add your own html" box. Not sure what they are doing with their code. But I found this solution at https://benmarshall.me/responsive-iframes/ and it works perfectly.

CSS

.iframe-container {
  overflow: hidden;
  padding-top: 56.25%;
  position: relative;
}

.iframe-container iframe {
   border: 0;
   height: 100%;
   left: 0;
   position: absolute;
   top: 0;
   width: 100%;
}

/* 4x3 Aspect Ratio */
.iframe-container-4x3 {
  padding-top: 75%;
}

HTML

<div class="iframe-container">
  <iframe src="https://player.vimeo.com/video/106466360" allowfullscreen></iframe>
</div>

Having the same error trying to install matplotlib for Python 3, those solutions didn't work for me. It was just a matter of dependencies, though it wasn't clear in the error message.

I used sudo apt-get build-dep python3-matplotlib then sudo pip3 install matplotlib and it worked.

Hope it'll help !

You can do something like this in you getJsonResponse function -

jData, err := json.Marshal(Data)
if err != nil {
    // handle error
}
w.Header().Set("Content-Type", "application/json")
w.Write(jData)

To get floating point result simply use:

round(x-0.5)

It works for negative numbers as well.

This should display the image inline:

.content-dir-item img.mail {
    display: inline-block;
    *display: inline; /* for older IE */
    *zoom: 1; /* for older IE */
}

As John Saunders says, check if the class/property names matches the capital casing of your XML. If this isn't the case, the problem will also occur.

Using angular-google-maps

$scope.bounds = new google.maps.LatLngBounds();
for (var i = $scope.markers.length - 1; i >= 0; i--) {
    $scope.bounds.extend(new google.maps.LatLng($scope.markers[i].coords.latitude, $scope.markers[i].coords.longitude));
};    
$scope.control.getGMap().fitBounds($scope.bounds);
$scope.control.getGMap().setCenter($scope.bounds.getCenter());

You got a bunch of good answers, so I'll just throw out a suggestion. If you are going to be working on this project for more than 2 days, download eclipse or netbeans and build your project in there.

If you are not normally a java programmer, then the help it will give you will be invaluable.

It's not worth the 1/2 hour download/install if you are only spending 2 hours on it.

Both have hotkeys/menu items to "Fix imports", with this you should never have to worry about imports again.

Since version 3.8.2 of SQLite, an alternative to explicit NOT NULL specifications is the "WITHOUT ROWID" specification: [1]

NOT NULL is enforced on every column of the PRIMARY KEY
in a WITHOUT ROWID table.

"WITHOUT ROWID" tables have potential efficiency advantages, so a less verbose alternative to consider is:

CREATE TABLE t (
  c1, 
  c2, 
  c3, 
  PRIMARY KEY (c1, c2)
 ) WITHOUT ROWID;

For example, at the sqlite3 prompt: sqlite> insert into t values(1,null,3); Error: NOT NULL constraint failed: t.c2

First-level cache

Hibernate tries to defer the Persistence Context flushing up until the last possible moment. This strategy has been traditionally known as transactional write-behind.

The write-behind is more related to Hibernate flushing rather than any logical or physical transaction. During a transaction, the flush may occur multiple times.

The flushed changes are visible only for the current database transaction. Until the current transaction is committed, no change is visible by other concurrent transactions.

Due to the first-level cache, Hibernate can do several optimizations:

• JDBC statement batching
• prevent lost update anomalies

Second-level cache

A proper caching solution would have to span across multiple Hibernate Sessions and that’s the reason Hibernate supports an additional second-level cache as well.

The second-level cache is bound to the SessionFactory life-cycle, so it’s destroyed only when the SessionFactory is closed (typically when the application is shutting down). The second-level cache is primarily entity-based oriented, although it supports an optional query-caching solution as well.

When loading an entity, Hibernate will execute the following actions:

1. If the entity is stored in the first-level cache, then the cached object reference is returned. This ensures application-level repeatable reads.
2. If the entity is not stored in the first-level cache and the second-level cache is activated, then Hibernate checks if the entity has been cached in the second-level cache, and if it were, it returns it to the caller.
3. Otherwise, if the entity is not stored in the first or second-level cache, it will be loaded from the DB.

An alternative: you can use a "hidden" applet element which implements this exist-check using a privileged action object and override your run method by:

File file = new File(yourPath);
return file.exists();

To accessing member functions or variables from one scope to another scope (In your case one method to another method we need to refer method or variable with class object. and you can do it by referring with self keyword which refer as class object.

class YourClass():

    def your_function(self, *args):

        self.callable_function(param) # if you need to pass any parameter

    def callable_function(self, *params): 
        print('Your param:', param)

You can try to get locale from system resources:

PackageManager packageManager = context.getPackageManager();
Resources resources = packageManager.getResourcesForApplication("android");
String language = resources.getConfiguration().locale.getLanguage();

The HAVING option can be used for this purpose and query should be

SELECT word, COUNT(*) FROM words 
GROUP BY word
HAVING COUNT(*) > 1;

I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands

OP, you can convert a string to type Boolean by using any of the methods stated below:

 string sample = "True";
 bool myBool = bool.Parse(sample);

 ///or

 bool myBool = Convert.ToBoolean(sample);

bool.Parse expects one parameter which in this case is sample, .ToBoolean also expects one parameter.

You can use TryParse which is the same as Parse but it doesn't throw any exception :)

  string sample = "false";
  Boolean myBool;

  if (Boolean.TryParse(sample , out myBool))
  {
  }

Please note that you cannot convert any type of string to type Boolean because the value of a Boolean can only be True or False

Hope you understand :)

Casting never needs a new:

Collection<T> collection = myList;

You don't even make the cast explicit, because Collection is a super-type of List, so it will work just like this.

In addition from the command prompt run SET.

This displayed the "LOGONSERVER" value which indicates the specific domain controller you are using (there can be more than one).

Then you got to that server's NetBios Share \Servername\SYSVOL\domain.local\scripts.

static void Main(string[] args)
{
  // For the sake of this example, we're just printing the arguments to the console.
  for (int i = 0; i < args.Length; i++) {
    Console.WriteLine("args[{0}] == {1}", i, args[i]);
  }
}

The arguments will then be stored in the args string array:

$ AppB.exe firstArg secondArg thirdArg
args[0] == firstArg
args[1] == secondArg
args[2] == thirdArg

Twitter has a public API which returns JSON, for example -

https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=mralexgray&count=1,

EDIT: Removed due to twitter restricting their API with OAUTH requirements...

{"errors": [{"message": "The Twitter REST API v1 is no longer active. Please migrate to API v1.1. https://dev.twitter.com/docs/api/1.1/overview.", "code": 68}]}

Replacing it with a simple example of the Github API - that returns a tree, of in this case, my repositories...

https://api.github.com/users/mralexgray/repos

I won't include the output, as it's long.. (returns 30 repos at a time) ... But here is proof of it's tree-ed-ness.

Unfortunately, it seems that proxy information must be set on each call to http.request. Node does not include a mechanism for global proxy settings.

The global-tunnel-ng module on NPM appears to handle this, however:

var globalTunnel = require('global-tunnel-ng');

globalTunnel.initialize({
  host: '10.0.0.10',
  port: 8080,
  proxyAuth: 'userId:password', // optional authentication
  sockets: 50 // optional pool size for each http and https
});

After the global settings are establish with a call to initialize, both http.request and the request library will use the proxy information.

The module can also use the http_proxy environment variable:

process.env.http_proxy = 'http://proxy.example.com:3129';
globalTunnel.initialize();

var selectList = db.NewsClasses.ToList<NewsClass>().Select(a => new SelectListItem({
    Text = a.ClassName,
    Value = a.ClassId.ToString()
});

Firstly, convert to object, then toString() will be correct.

From PowerShell you can use the .NET [System.Environment]::SetEnvironmentVariable() method:

• To remove a user environment variable named FOO:

  [Environment]::SetEnvironmentVariable('FOO', $null, 'User')
  

^{Note that $null is used to better signal the intent to remove the variable, though technically it is effectively the same as passing '' in this case.}

• To remove a system (machine-level) environment variable named FOO - requires elevation (must be run as administrator):

  [Environment]::SetEnvironmentVariable('FOO', $null, 'Machine')
  

Aside from faster execution, the advantage over the reg.exe-based method is that other applications are notified of the change, via a WM_SETTINGCHANGE message (though not all applications listen to that message).

If you need to order the files by specific parameter (e.g. date time):

gci *.log | sort LastWriteTime | % {$(Get-Content $_)} | Set-Content result.log

Depends on what your native code does, but v7a has support for hardware floating point operations, which makes a huge difference. armeabi will work fine on all devices, but will be a lot slower, and won't take advantage of newer devices' CPU capabilities. Do take some benchmarks for your particular application, but removing the armeabi-v7a binaries is generally not a good idea. If you need to reduce size, you might want to have two separate apks for older (armeabi) and newer (armeabi-v7a) devices.

You can find your Arduino via Terminal with

 ls /dev/tty.*

then you can read that serial port using the screen command, like this

screen /dev/tty.[yourSerialPortName] [yourBaudRate]

for example:

screen /dev/tty.usbserial-A6004byf 9600

Bind any html input

<input id="element-to-bind" type="text">

define two functions:

function bindValue(objectToBind) {
var elemToBind = document.getElementById(objectToBind.id)    
elemToBind.addEventListener("change", function() {
    objectToBind.value = this.value;
})
}

function proxify(id) { 
var handler = {
    set: function(target, key, value, receiver) {
        target[key] = value;
        document.getElementById(target.id).value = value;
        return Reflect.set(target, key, value);
    },
}
return new Proxy({id: id}, handler);
}

use the functions:

var myObject = proxify('element-to-bind')
bindValue(myObject);

By default you can't use PHP in HTML pages.

To do that, modify your .htacccess file with the following:

AddType application/x-httpd-php .html

I have also found that you can use verbose=2 to make keras print out the Losses:

history = model.fit(X, Y, validation_split=0.33, nb_epoch=150, batch_size=10, verbose=2)

And that would print nice lines like this:

Epoch 1/1
 - 5s - loss: 0.6046 - acc: 0.9999 - val_loss: 0.4403 - val_acc: 0.9999

According to their documentation:

verbose: 0, 1, or 2. Verbosity mode. 0 = silent, 1 = progress bar, 2 = one line per epoch.

You can't call free on the pointers returned from strsep. Those are not individually allocated strings, but just pointers into the string s that you've already allocated. When you're done with s altogether, you should free it, but you do not have to do that with the return values of strsep.

This code will dynamically generate the expression for you with the nested clauses. I have a scenario where the number of "OR" s was unknown, so I'm using the below. Usage:

        private static void Main(string[] args)
        {
            var query = new PropertyString(@"<Query><Where>{{WhereClauses}}</Where></Query>");
            var whereClause =
                new PropertyString(@"<Eq><FieldRef Name='ID'/><Value Type='Counter'>{{NestClauseValue}}</Value></Eq>");
            var andClause = new PropertyString("<Or>{{FirstExpression}}{{SecondExpression}}</Or>");

            string[] values = {"1", "2", "3", "4", "5", "6"};

            query["WhereClauses"] = NestEq(whereClause, andClause, values);

            Console.WriteLine(query);
        }

And here's the code:

   private static string MakeExpression(PropertyString nestClause, string value)
        {
            var expr = nestClause.New();
            expr["NestClauseValue"] = value;
            return expr.ToString();
        }

        /// <summary>
        /// Recursively nests the clause with the nesting expression, until nestClauseValue is empty.
        /// </summary>
        /// <param name="whereClause"> A property string in the following format: <Eq><FieldRef Name='Title'/><Value Type='Text'>{{NestClauseValue}}</Value></Eq>"; </param>
        /// <param name="nestingExpression"> A property string in the following format: <And>{{FirstExpression}}{{SecondExpression}}</And> </param>
        /// <param name="nestClauseValues">A string value which NestClauseValue will be filled in with.</param>
        public static string NestEq(PropertyString whereClause, PropertyString nestingExpression, string[] nestClauseValues, int pos=0)
        {
            if (pos > nestClauseValues.Length)
            {
                return "";
            }

            if (nestClauseValues.Length == 1)
            {
                return MakeExpression(whereClause, nestClauseValues[0]);
            }

            var expr = nestingExpression.New();
            if (pos == nestClauseValues.Length - 2)
            {
                expr["FirstExpression"] = MakeExpression(whereClause, nestClauseValues[pos]);
                expr["SecondExpression"] = MakeExpression(whereClause, nestClauseValues[pos + 1]);
                return expr.ToString();
            }
            else
            {
                expr["FirstExpression"] = MakeExpression(whereClause, nestClauseValues[pos]);
                expr["SecondExpression"] = NestEq(whereClause, nestingExpression, nestClauseValues, pos + 1);
                return expr.ToString();
            }
        }

        }

        private Dictionary<string, string> _properties;

                modifiedStr = modifiedStr.Replace("{{" + keyvaluePair.Key + "}}", keyvaluePair.Value);
            }

            return modifiedStr;
        }
    }

You can simply use:

if($_POST['username'] and $_POST['password']){
  $username = $_POST['username'];
  $password = $_POST['password'];
}

Alternatively, use empty()

if(!empty($_POST['username']) and !empty($_POST['password'])){
  $username = $_POST['username'];
  $password = $_POST['password'];
}

I think you've missed the point of access control.

A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.

Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.

In your specific case, it seems that paste.ee doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).

If you're on Ubuntu, you might have an old version of postgresql-client installed. Based on the versions in your error message, the solution would be the following:

sudo apt-get remove postgresql-client-9.1
sudo apt-get install postgresql-client-9.2

This might not suit everyone since it does not preserve the original file permissions but in my case it was not important and it solved the problem for me. rsync has an option --chmod:

--chmod This option tells rsync to apply one or more comma-separated lqchmodrq strings to the permission of the files in the transfer. The resulting value is treated as though it was the permissions that the sending side supplied for the file, which means that this option can seem to have no effect on existing files if --perms is not enabled.

This forces the permissions to be what you want on all files/directories. For example:

rsync -av --chmod=Du+rwx SRC DST

would add Read, Write and Execute for the user to all transferred directories.

Array list can be implemented by the following code:

Arraylist<String> list = new ArrayList<String>();
list.add(value1);
list.add(value2);
list.add(value3);
list.add(value4);

You need to have your function in the componentDidMount lifecycle since this is the function that is called when the DOM has loaded.

Make use of refs to access the DOM element

<input type="submit" className="nameInput" id="name" value="cp-dev1" onClick={this.writeData} ref = "cpDev1"/>

  componentDidMount: function(){
    var name = React.findDOMNode(this.refs.cpDev1).value;
    this.someOtherFunction(name);
  }

See this answer for more info on How to access the dom element in React

If you want to use the back button, check this out. https://stackoverflow.com/questions/116446/what-is-the-best-back-button-jquery-plugin

Use document.location.href to change the page location, place it in the function on a successful ajax run.

Plugins -> Plugin Manager -> Show Plugin Manager -> Setting -> Check mark On Force HTTP instead of HTTPS for downloading Plugin List & Use development plugin list (may contain untested, unvalidated or un-installable plugins). -> OK.

Note, not only there is dependency on .panel, it also has dependency on the DOM structure.

Make sure your elements are structured like this:

    <div id="parent-id">
        <div class="panel">
            <a data-toggle="collapse" data-target="#opt1" data-parent="#parent-id">Control</a>
            <div id="opt1" class="collapse">
...

It's basically what @Blazemonger said, but I think the hierarchy of the target element matters too. I didn't finish trying every possibility out, but basically it should work if you follow this hierarchy.

FYI, I had more layers between the control div & content div and that didn't work.

use HASHBYTES

declare @first_value nvarchar(1) = 'a'
declare @second_value navarchar(1) = 'A'

if HASHBYTES('SHA1',@first_value) = HASHBYTES('SHA1',@second_value) begin
    print 'equal'
end else begin
    print 'not equal'
end

-- output:
-- not equal

...in where clause

declare @example table (ValueA nvarchar(1), ValueB nvarchar(1))

insert into @example (ValueA, ValueB)
values  ('a', 'A'),
        ('a', 'a'),
        ('a', 'b')

select  ValueA + ' = ' + ValueB
from    @example
where   hashbytes('SHA1', ValueA) = hashbytes('SHA1', ValueB)

-- output:
-- a = a

select  ValueA + ' <> ' + ValueB
from    @example
where   hashbytes('SHA1', ValueA) <> hashbytes('SHA1', ValueB)

-- output:
-- a <> A
-- a <> b

or to find a value

declare @value_b nvarchar(1) = 'A'

select  ValueB + ' = ' + @value_b
from    @example
where   hashbytes('SHA1', ValueB) = hasbytes('SHA1', @value_b)

-- output:
-- A = A

I disagree with the accepted answer being "the easiest", particularly if you want to use virtualenv.

You can use the Unofficial Windows Binaries instead. Download the appropriate wheel from there, and install it with pip:

pip install pywin32-219-cp27-none-win32.whl

(Make sure you pick the one for the right version and bitness of Python).

You might be able to get the URL and install it via pip without downloading it first, but they're made it a bit harder to just grab the URL. Probably better to download it and host it somewhere yourself.

I added this to my pom.xml below the project description and it worked:

<properties>
    <maven.compiler.source>1.6</maven.compiler.source>
    <maven.compiler.target>1.6</maven.compiler.target>
</properties>

It is also worth noting that in the cascade, an id (#) selector is more specific than a b (.) selector. Therefore, rules in the id statement will override rules in the class statement.

For example, if both of the following statements:

.headline {
  color:red;
  font-size: 3em;
}

#specials {
  color:blue;
  font-style: italic;
}

are applied to the same HTML element:

<h1 id="specials" class="headline">Today's Specials</h1>

the color:blue rule would override the color:red rule.

Use display:none;

<div id="divCheckbox" style="display: none;">

• visibility: hidden hides the element, but it still takes up space in the layout.

• display: none removes the element completely from the document, it doesn't take up any space.

How to figure it out

Start with npm root -- it will show you the root folder for NPM packages for the current user. Add -g and you get a global folder. Don't forget to substract node_modules.

Use npm config / npm config -g and check that it'd create you a new .npmrc / npmrc file for you.

Tested on Windows 10 Pro, NPM v.6.4.1:

Global NPM config

C:\Users\%username%\AppData\Roaming\npm\etc\npmrc

Per-user NPM config

C:\Users\%username%\.npmrc

Built-in NPM config

C:\Program Files\nodejs\node_modules\npm\npmrc

for LocalBroadcastManager

   Intent intent = new Intent("any.action.string");
   LocalBroadcastManager.getInstance(context).
                                sendBroadcast(intent);

and register in onResume

LocalBroadcastManager.getInstance(
                    ActivityName.this).registerReceiver(chatCountBroadcastReceiver, filter);

and Unregister it onStop

LocalBroadcastManager.getInstance(
                ActivityName.this).unregisterReceiver(chatCountBroadcastReceiver);

and recieve it ..

mBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.e("mBroadcastReceiver", "onReceive");
        }
    };

where IntentFilter is

 new IntentFilter("any.action.string")

Another type of solution would be to autogenerate the nginx conf files via Jinja2 templates from ansible. The advantage of this is easy deployment to a cloud environment, and easy to replicate on multiple dev machines

Solution for loading an external website into an iFrame even tough the x-frame option is set to deny on the external website.

If you want to load a other website into an iFrame and you get the Display forbidden by X-Frame-Options” error then you can actually overcome this by creating a server side proxy script.

The src attribute of the iFrame could have an url looking like this: /proxy.php?url=https://www.example.com/page&key=somekey

Then proxy.php would look something like:

if (isValidRequest()) {
   echo file_get_contents($_GET['url']);
}

function isValidRequest() {
    return $_SERVER['REQUEST_METHOD'] === 'GET' && isset($_GET['key']) && 
    $_GET['key'] === 'somekey';
}

This by passes the block, because it is just a GET request that might as wel have been a ordinary browser page visit.

Be aware: You might want to improve the security in this script. Because hackers could start loading in webpages via your proxy script.

I meet the same problem,but ,at last I solve the problem by followed way

((ViewGroup)dialog.getWindow().getDecorView())
.getChildAt(0).startAnimation(AnimationUtils.loadAnimation(
context,android.R.anim.slide_in_left));

Ok, so this piece of code should work for you. I changed the names to match your parameter.

inFile.seekg(0, ios::end);  
if (inFile.tellg() == 0) {    
  // ...do something with empty file...  
}

You can try this code (requires jQuery):

<html>
<head>
    <script type="text/javascript" src="jquery.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $('#foo').keyup(function(e) {
                var v = $('#foo').val();
                $('#debug').val(v);
            })
        });
    </script>
</head>
<body>
    <form>
        <input type="text" id="foo" value="bar"><br>
        <textarea id="debug"></textarea>
    </form>
</body>
</html>

If you are a Windows user and you are using conda to manage the environment in Anaconda prompt, you can do the following:

Make sure you deactivate the virtual environment or restart Anaconda Prompt. Use the following command to remove virtual environment:

$ conda env remove --name $MyEnvironmentName

Alternatively, you can go to the

C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\envs\MYENVIRONMENTNAME

(that's the default file path) and delete the folder manually.

The simplest way is to set the frame of your UIImageView and set the contentMode to one of the resizing options.

Or you can use this utility method, if you actually need to resize an image:

+ (UIImage *)imageWithImage:(UIImage *)image scaledToSize:(CGSize)newSize {
    //UIGraphicsBeginImageContext(newSize);
    // In next line, pass 0.0 to use the current device's pixel scaling factor (and thus account for Retina resolution).
    // Pass 1.0 to force exact pixel size.
    UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
    [image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();    
    UIGraphicsEndImageContext();
    return newImage;
}

Example usage:

#import "MYUtil.h"
…
UIImage *myIcon = [MYUtil imageWithImage:myUIImageInstance scaledToSize:CGSizeMake(20, 20)];

Solved, use array list of string to get name from Ingredients. Use below code:

JSONObject jsonObj = new JSONObject(jsonStr);

//extracting data array from json string
JSONArray ja_data = jsonObj.getJSONArray("data");
int length = ja_data.length();

//loop to get all json objects from data json array
for(int i=0; i<length; i++){
    JSONObject jObj = ja_data.getJSONObject(i);
    Toast.makeText(this, jObj.getString("Name"), Toast.LENGTH_LONG).show();
    // getting inner array Ingredients
    JSONArray ja = jObj.getJSONArray("Ingredients");
    int len = ja.length();
    ArrayList<String> Ingredients_names = new ArrayList<>();
    for(int j=0; j<len; j++){
        JSONObject json = ja.getJSONObject(j);
        Ingredients_names.add(json.getString("name"));
    }
}

I had the same problem. All the git commands accessing remote git repository are hanging. I forgot that I changed my VM network settings. Once I changed it back to NAT (as before) then they started working. It is not an issue with the git but with the network itself.

JVM is abbreviated as Java Virtual Machine, JVM is the main component of java architecture. JVM is written in C programming language. Java compiler produce the byte code for JVM. JVM reading the byte code verifying the byte code and linking the code with the ibrary.

JRE is abbreviated as Java Runtime Environment. it is provide environment at runtime. It is physically exist. It contain JVM + set of libraries(jar) +other files.

JDK is abbreviated as Java Development Kit . it is develop java applications. And also Debugging and monitoring java applications . JDK contain JRE +development tools(javac,java)

OpenJDK OpenJDK is an open source version of sun JDK. Oracle JDK is Sun's official JDK.

unnest can be used as well. It expands array to a set of rows and then simply checking a value exists or not is as simple as using IN or NOT IN.

e.g.

1. id => uuid

2. exception_list_ids => uuid[]

select * from table where id NOT IN (select unnest(exception_list_ids) from table2)

We are running Linux, a mostly POSIX-compliant OS. POSIX standards it should be: Utility Argument Syntax.

• An option is a hyphen followed by a single alphanumeric character, like this: -o.
• An option may require an argument (which must appear immediately after the option); for example, -o argument or -oargument.
• Options that do not require arguments can be grouped after a hyphen, so, for example, -lst is equivalent to -t -l -s.
• Options can appear in any order; thus -lst is equivalent to -tls.
• Options can appear multiple times.
• Options precede other nonoption arguments: -lst nonoption.
• The -- argument terminates options.
• The - option is typically used to represent one of the standard input streams.

Use ALTER SESSION statements to set comparison to case-insensitive:

alter session set NLS_COMP=LINGUISTIC;
alter session set NLS_SORT=BINARY_CI;

If you're still using version 10gR2, use the below statements. See this FAQ for details.

alter session set NLS_COMP=ANSI;
alter session set NLS_SORT=BINARY_CI;

We can use

public StreamWriter(string path, bool append);

while opening the file

string path="C:\\MyFolder\\Notes.txt"
StreamWriter writer = new StreamWriter(path, true);

First parameter is a string to hold a full file path Second parameter is Append Mode, that in this case is made true

Writing to the file can be done with:

writer.Write(string)

or

writer.WriteLine(string)

Sample Code

private void WriteAndAppend()
{
            string Path = Application.StartupPath + "\\notes.txt";
            FileInfo fi = new FileInfo(Path);
            StreamWriter SW;
            StreamReader SR;
            if (fi.Exists)
            {
                SR = new StreamReader(Path);
                string Line = "";
                while (!SR.EndOfStream) // Till the last line
                {
                    Line = SR.ReadLine();
                }
                SR.Close();
                int x = 0;
                if (Line.Trim().Length <= 0)
                {
                    x = 0;
                }
                else
                {
                    x = Convert.ToInt32(Line.Substring(0, Line.IndexOf('.')));
                }
                x++;
                SW = new StreamWriter(Path, true);
                SW.WriteLine("-----"+string.Format("{0:dd-MMM-yyyy hh:mm:ss tt}", DateTime.Now));
                SW.WriteLine(x.ToString() + "." + textBox1.Text);

            }
            else
            {
                SW = new StreamWriter(Path);
                SW.WriteLine("-----" + string.Format("{0:dd-MMM-yyyy hh:mm:ss tt}", DateTime.Now));
                SW.WriteLine("1." + textBox1.Text);
            }
            SW.Flush();
            SW.Close();
        }

After trying a number of suggested solutions without success I just rebooted my PC. After that the problem didn't occur anymore.

If you have access to the script console (Manage Jenkins -> Script Console), then you can do this following:

Jenkins.instance.getItemByFullName("YourJobName").updateNextBuildNumber(45)

There is a massive difference in the example you have posted, the first version:

var urls = await context.Urls.ToListAsync();

This is bad, it basically does select * from table, returns all results into memory and then applies the where against that in memory collection rather than doing select * from table where... against the database.

The second method will not actually hit the database until a query is applied to the IQueryable (probably via a linq .Where().Select() style operation which will only return the db values which match the query.

If your examples were comparable, the async version will usually be slightly slower per request as there is more overhead in the state machine which the compiler generates to allow the async functionality.

However the major difference (and benefit) is that the async version allows more concurrent requests as it doesn't block the processing thread whilst it is waiting for IO to complete (db query, file access, web request etc).

According to the spec RFC 2045 #Syntax of the Content-Type Header Field application/myappname is not allowed, but application/x-myappname is allowed and sounds most appropriate for you're application to me.

This is not a solution but I hope it helps: This comes close except that when the KEY = %userprofile%\desktop the copy fails even though zdesktop=%userprofile%\desktop. I think because the embedded %userprofile% is not getting translated.

REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop>z.out
for /f "tokens=3 skip=4" %%t in (z.out) do set zdesktop=%%t
copy myicon %zdesktop%
set zdesktop=
del z.out

So it sucessfully parses out the REG key but if the key contains an embedded %var% it doesn't get translated during the copy command.

By default the database in a project in the Firebase Console is only readable/writeable by administrative users (e.g. in Cloud Functions, or processes that use an Admin SDK). Users of the regular client-side SDKs can't access the database, unless you change the server-side security rules.

You can change the rules so that the database is only readable/writeable by authenticated users:

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}

See the quickstart for the Firebase Database security rules.

But since you're not signing the user in from your code, the database denies you access to the data. To solve that you will either need to allow unauthenticated access to your database, or sign in the user before accessing the database.

Allow unauthenticated access to your database

The simplest workaround for the moment (until the tutorial gets updated) is to go into the Database panel in the console for you project, select the Rules tab and replace the contents with these rules:

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

This makes your new database readable and writeable by anyone who knows the database's URL. Be sure to secure your database again before you go into production, otherwise somebody is likely to start abusing it.

Sign in the user before accessing the database

For a (slightly) more time-consuming, but more secure, solution, call one of the signIn... methods of Firebase Authentication to ensure the user is signed in before accessing the database. The simplest way to do this is using anonymous authentication:

firebase.auth().signInAnonymously().catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // ...
});

And then attach your listeners when the sign-in is detected

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    // User is signed in.

Your best bet is probably to use pygame/SDL. It's an external library, but it has great support across platforms.

pygame.mixer.init()
pygame.mixer.music.load("file.mp3")
pygame.mixer.music.play()

You can find more specific documentation about the audio mixer support in the pygame.mixer.music documentation

So I follow first answer, but my vnc viewer gives me grey screen when I connect to it. And I found this Ask Ubuntu link to solve that.

The only difference with previous answer is you need to install these extra packages:

apt-get install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal

And use this ~/.vnc/xstartup file:

#!/bin/sh

export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &

gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal &

Everything else is the same.

Tested on EC2 Ubuntu 14.04 LTS.

I'll put in my two cents for tapply().

tapply(df$dt, df$group, summary)

You could write a custom function with the specific statistics you want to replace summary.

In SQL Developer: Everything was working fine and I had all the permissions to login and there was no password change and I could click the table and see the data tab.

But when I run query (simple select statement) it was showing "ORA-01031: insufficient privileges" message.

The solution is simply disconnect the connection and reconnect. Note: only doing Reconnect did not work for me. SQL Developer Disconnect Snapshot

For anyone still looking to use the aforementioned IMAP library but need to use gradle, simply add this line to your modules gradle file (not the main gradle file)

compile group: 'javax.mail', name: 'mail', version: '1.4.1'

The links to download the .jar file were dead for me, so had to go with an alternate route.

Hope this helps :)

A session is stored server side, you can't modify it with JavaScript. Sessions may contain sensitive data.

You can modify cookies using document.cookie.

You can easily find many examples how to modify cookies.

Just Use This:

import datetime
today = datetime.datetime.today()
nextMonthDatetime = today + datetime.timedelta(days=(today.max.day - today.day)+1)

Below code will only print files within directory and exclude directories within given directory while traversing.

#include <dirent.h>
#include <stdio.h>
#include <errno.h>
#include <sys/stat.h>
#include<string.h>
int main(void)
{
    DIR *d;
    struct dirent *dir;
    char path[1000]="/home/joy/Downloads";
    d = opendir(path);
    char full_path[1000];
    if (d)
    {
        while ((dir = readdir(d)) != NULL)
        {
            //Condition to check regular file.
            if(dir->d_type==DT_REG){
                full_path[0]='\0';
                strcat(full_path,path);
                strcat(full_path,"/");
                strcat(full_path,dir->d_name);
                printf("%s\n",full_path);
            }
        }
        closedir(d);
    }
    return(0);     
}

An other approach is to use splice.

The splice() method changes the contents of an array by removing or replacing existing elements and/or adding new elements in place.

N.B : In case you're working with reactive frameworks, it will update the "view", your array "knowing" you've updated it.

Answer :

var item = {...}
var items = [{id:2}, {id:2}, {id:2}];

let foundIndex = items.findIndex(element => element.id === item.id)
items.splice(foundIndex, 1, item)

And in case you want to only change a value of an item, you can use find function :

// Retrieve item and assign ref to updatedItem
let updatedItem = items.find((element) => { return element.id === item.id })

// Modify object property
updatedItem.aProp = ds.aProp

Try below code snippet

if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) 
   && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') 
  {
    /* This is one ajax call */
  }

Use empty (it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"

If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"

Update: as per the comments, the Map turns out to actually be a List (please work on your naming conventions). To check if a List contains an item the "normal" EL way, use JSTL fn:contains (although not explicitly documented, it works for List as well).

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

I'm using monotouch, so the names and code will be a bit different, but you can do this by making sure that the width of the collectionview equals (x * cell width) + (x-1) * MinimumSpacing with x = amount of cells per row.

Just do following steps based on your MinimumInteritemSpacing and the Width of the Cell

1) We calculate amount of items per row based on cell size + current insets + minimum spacing

float currentTotalWidth = CollectionView.Frame.Width - Layout.SectionInset.Left - Layout.SectionInset.Right (Layout = flowlayout)
int amountOfCellsPerRow = (currentTotalWidth + MinimumSpacing) / (cell width + MinimumSpacing)

2) Now you have all info to calculate the expected width for the collection view

float totalWidth =(amountOfCellsPerRow * cell width) + (amountOfCellsPerRow-1) * MinimumSpacing

3) So the difference between the current width and the expected width is

float difference = currentTotalWidth - totalWidth;

4) Now adjust the insets (in this example we add it to the right, so the left position of the collectionview stays the same

Layout.SectionInset.Right = Layout.SectionInset.Right + difference;

Disclaimer: I have read this question for days, but it is beyond my knowledge to understand the math.

I tried to solve it using set:

arr=[1,2,4,5,7,8,10] # missing 3,6,9
NMissing=3
arr_origin = list(range(1,arr[-1]+1))

for i in range(NMissing):
      arr.append(arr[-1]) ##### assuming you do not delete the last one

arr=set(arr)
arr_origin=set(arr_origin)
missing=arr_origin-arr # 3 6 9
