ConfigurationManager.AppSettings returns the settings defined for the application, not for the specific DLL, you can access them but it's the application settings that will be returned.

If you're using you dll from another application then the ConnectionString shall be in the app.settings of the application.

*Using Robot class you can do this, Try following code:

Actions action = new Actions(driver);
action.contextClick(WebElement).build().perform();
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_DOWN);
robot.keyRelease(KeyEvent.VK_DOWN);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);

[UPDATE]

CAUTION: Your Browser should always be in focus i.e. running in foreground while performing Robot Actions, other-wise any other application in foreground will receive the actions.

Just to simplify -

Entity framework doesn't support primitives. You either create a class to wrap it or add another property to format the list as a string:

public ICollection<string> List { get; set; }
public string ListString
{
    get { return string.Join(",", List); }
    set { List = value.Split(',').ToList(); }
}

If you're going across machines, you either need to be using NETWORK SERVICE, LOCAL SYSTEM, a domain account, or a SQL 2008 R2 (if you have it) Managed Service Account (which is my preference if you had such an infrastructure). You can not use an account which is not visible to the Active Directory domain.

function disableItems(divSelector){
    var disableInputs = $(divSelector).find(":input").not("[disabled]");
    disableInputs.attr("data-reenable", true);
    disableInputs.attr("disabled", true);
}

function reEnableItems(divSelector){
    var reenableInputs = $(divSelector).find("[data-reenable]");
    reenableInputs.removeAttr("disabled");
    reenableInputs.removeAttr("data-reenable");
}

You can use RIGHT :

 select RIGHT(123.45,2) return => 45

Here's one way:

Stream myStream = null;
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = theDialog.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
    }
}

Modified from here:MSDN OpenFileDialog.OpenFile

EDIT Here's another way more suited to your needs:

private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
    OpenFileDialog theDialog = new OpenFileDialog();
    theDialog.Title = "Open Text File";
    theDialog.Filter = "TXT files|*.txt";
    theDialog.InitialDirectory = @"C:\";
    if (theDialog.ShowDialog() == DialogResult.OK)
    {
        string filename = theDialog.FileName;

        string[] filelines = File.ReadAllLines(filename);

        List<Employee> employeeList = new List<Employee>();
        int linesPerEmployee = 4;
        int currEmployeeLine = 0;
        //parse line by line into instance of employee class
        Employee employee = new Employee();
        for (int a = 0; a < filelines.Length; a++)
        {

            //check if to move to next employee
            if (a != 0 && a % linesPerEmployee == 0)
            {
                employeeList.Add(employee);
                employee = new Employee();
                currEmployeeLine = 1;
            }

            else
            {
                currEmployeeLine++;
            }
            switch (currEmployeeLine)
            {
                case 1:
                    employee.EmployeeNum = Convert.ToInt32(filelines[a].Trim());
                    break;
                case 2:
                    employee.Name = filelines[a].Trim();
                    break;
                case 3:
                    employee.Address = filelines[a].Trim();
                    break;
                case 4:
                    string[] splitLines = filelines[a].Split(' ');

                    employee.Wage = Convert.ToDouble(splitLines[0].Trim());
                    employee.Hours = Convert.ToDouble(splitLines[1].Trim());
                    break;


            }

        }
        //Test to see if it works
        foreach (Employee emp in employeeList)
        {
            MessageBox.Show(emp.EmployeeNum + Environment.NewLine +
                emp.Name + Environment.NewLine +
                emp.Address + Environment.NewLine +
                emp.Wage + Environment.NewLine +
                emp.Hours + Environment.NewLine);
        }
    }
}

Android Text Justify For TextView XML

Simply android text-justify using in XML. You can simply implement in textview widget.

 <TextView
    android:justificationMode="inter_word"
/>

Default is android:justificationMode="none"

As Constructor should be at the starting of the Class , you are facing the above issue . So, you can either change the name or if you want to use it as a constructor just copy the method at the beginning of the class.

Also use NVL2 as below if you want to return other value from the field_to_check:

NVL2( field_to_check, value_if_NOT_null, value_if_null )

Usage: ORACLE/PLSQL: NVL2 FUNCTION

Like Other said you can use something like that:

IF NOT EXISTS (SELECT 1 FROM Table)
  BEGIN 
    --Do Something
  END 
ELSE
  BEGIN
    --Do Another Thing
  END

For further visitors:

// Executes: SELECT * FROM mytable LIMIT 10 OFFSET 20
// get([$table = ''[, $limit = NULL[, $offset = NULL]]])
$query = $this->db->get('mytable', 10, 20);

// get_where sample, 
$query = $this->db->get_where('mytable', array('id' => $id), 10, 20);

// Produces: LIMIT 10
$this->db->limit(10);  

// Produces: LIMIT 10 OFFSET 20
// limit($value[, $offset = 0])
$this->db->limit(10, 20);

There is also the strncmp() function and strncasecmp() function which is perfect for this situation:

if (strncmp($string_n, "http", 4) === 0)

In general:

if (strncmp($string_n, $prefix, strlen($prefix)) === 0)

The advantage over the substr() approach is that strncmp() just does what needs to be done, without creating a temporary string.

Roughly you can do it like that :

try
{
    //do something
}
catch (Exception ex)
{
    string script = "<script>alert('" + ex.Message + "');</script>";
    if (!Page.IsStartupScriptRegistered("myErrorScript"))
    {
         Page.ClientScript.RegisterStartupScript("myErrorScript", script);
    }
}

But I recommend you to define your custom Exception and throw it anywhere you need. At your page catch this custom exception and register your message box script.

I think that you are looking for something like this:

   function rightclick() {
    var rightclick;
    var e = window.event;
    if (e.which) rightclick = (e.which == 3);
    else if (e.button) rightclick = (e.button == 2);
    alert(rightclick); // true or false, you can trap right click here by if comparison
}

(http://www.quirksmode.org/js/events_properties.html)

And then use the onmousedown even with the function rightclick() (if you want to use it globally on whole page you can do this <body onmousedown=rightclick(); >

INTRO: This answer was written in a time when Numpy was version 1.11 and behaviour of NAT comparison was supposed to change since version 1.12. Clearly that wasn't the case and the second part of answer became wrong. The first part of answer may be not applicable for new versions of numpy. Be sure you've checked MSeifert's answers below.

import numpy as np    
nat = np.datetime64('NaT')

def nat_check(nat):
    return nat == np.datetime64('NaT')    

nat_check(nat)
Out[4]: FutureWarning: In the future, 'NAT == x' and 'x == NAT' will always be False.
True

nat_check(nat)
Out[5]: True

If you want to suppress the warning you can use the catch_warnings context manager:

import numpy as np
import warnings

nat = np.datetime64('NaT')

def nat_check(nat):
    with warnings.catch_warnings():
        warnings.simplefilter("ignore")
        return nat == np.datetime64('NaT')    

nat_check(nat)
Out[5]: True

And finally you might check numpy version to handle changed behavior since version 1.12.0:

def nat_check(nat):
    if [int(x) for x in np.__version__.split('.')[:-1]] > [1, 11]:
        return nat != nat
    with warnings.catch_warnings():
        warnings.simplefilter("ignore")
        return nat == np.datetime64('NaT')

I would like to add a word of warning when you are dealing with C++11-style allocator-aware containers. Swapping and assignment have subtly different semantics.

For concreteness, let us consider a container std::vector<T, A>, where A is some stateful allocator type, and we'll compare the following functions:

void fs(std::vector<T, A> & a, std::vector<T, A> & b)
{ 
    a.swap(b);
    b.clear(); // not important what you do with b
}

void fm(std::vector<T, A> & a, std::vector<T, A> & b)
{
    a = std::move(b);
}

The purpose of both functions fs and fm is to give a the state that b had initially. However, there is a hidden question: What happens if a.get_allocator() != b.get_allocator()? The answer is: It depends. Let's write AT = std::allocator_traits<A>.

• If AT::propagate_on_container_move_assignment is std::true_type, then fm reassigns the allocator of a with the value of b.get_allocator(), otherwise it does not, and a continues to use its original allocator. In that case, the data elements need to be swapped individually, since the storage of a and b is not compatible.

• If AT::propagate_on_container_swap is std::true_type, then fs swaps both data and allocators in the expected fashion.

• If AT::propagate_on_container_swap is std::false_type, then we need a dynamic check.

  • If a.get_allocator() == b.get_allocator(), then the two containers use compatible storage, and swapping proceeds in the usual fashion.
  • However, if a.get_allocator() != b.get_allocator(), the program has undefined behaviour (cf. [container.requirements.general/8].

The upshot is that swapping has become a non-trivial operation in C++11 as soon as your container starts supporting stateful allocators. That's a somewhat "advanced use case", but it's not entirely unlikely, since move optimizations usually only become interesting once your class manages a resource, and memory is one of the most popular resources.

check properties->java build path -> libraries. there should be no errors, in my case there was errors in the maven. once I put the required jar in the maven repo, it worked fine

You can use ng-include directive.

Try something like this:

emanuel.directive('hymn', function() {
   return {
       restrict: 'E',
       link: function(scope, element, attrs) {
           scope.getContentUrl = function() {
                return 'content/excerpts/hymn-' + attrs.ver + '.html';
           }
       },
       template: '<div ng-include="getContentUrl()"></div>'
   }
});

UPD. for watching ver attribute

emanuel.directive('hymn', function() {
   return {
       restrict: 'E',
       link: function(scope, element, attrs) {
           scope.contentUrl = 'content/excerpts/hymn-' + attrs.ver + '.html';
           attrs.$observe("ver",function(v){
               scope.contentUrl = 'content/excerpts/hymn-' + v + '.html';
           });
       },
       template: '<div ng-include="contentUrl"></div>'
   }
});

The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.

I found a solution in the guide here:

http://www.samontab.com/web/2014/06/installing-opencv-2-4-9-in-ubuntu-14-04-lts/

I resorted to compiling and installing from source. The process was very smooth, had I known, I would have started with that instead of trying to find a more simple way to install. Hopefully this information is helpful to someone.

The same dialog asking for the KeyChain password has 3 buttons. Most likely the wanted password is that for logging in to your Mac. If you press "Allow" it only works for some tiny aspect and will ask again, which is very puzzling. You need to press "Always Allow". The verification team at Apple is very weak, they need some 'normal' developers in the design team for the chain of events to get an app in the app store. Normal developers have very sketchy ideas about KeyChains and Certificates and Profiles.

These parameters are typically used for proxy functions, so the proxy can pass any input parameter to the target function.

def foo(bar=2, baz=5):
    print bar, baz

def proxy(x, *args, **kwargs): # reqire parameter x and accept any number of additional arguments
    print x
    foo(*args, **kwargs) # applies the "non-x" parameter to foo

proxy(23, 5, baz='foo') # calls foo with bar=5 and baz=foo
proxy(6)# calls foo with its default arguments
proxy(7, bar='asdas') # calls foo with bar='asdas' and leave baz default argument

But since these parameters hide the actual parameter names, it is better to avoid them.

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

It's useful in situations where you have hidden internal state such as a cache. For example:

class HashTable
{
...
public:
    string lookup(string key) const
    {
        if(key == lastKey)
            return lastValue;

        string value = lookupInternal(key);

        lastKey = key;
        lastValue = value;

        return value;
    }

private:
    mutable string lastKey, lastValue;
};

And then you can have a const HashTable object still use its lookup() method, which modifies the internal cache.

This answer is for anyone encountering pdfs with images and needing to use OCR. I could not find a workable off-the-shelf solution; nothing that gave me the accuracy I needed.

Here are the steps I found to work.

1. Use pdfimages from https://poppler.freedesktop.org/ to turn the pages of the pdf into images.

2. Use Tesseract to detect rotation and ImageMagick mogrify to fix it.

3. Use OpenCV to find and extract tables.

4. Use OpenCV to find and extract each cell from the table.

5. Use OpenCV to crop and clean up each cell so that there is no noise that will confuse OCR software.

6. Use Tesseract to OCR each cell.

7. Combine the extracted text of each cell into the format you need.

I wrote a python package with modules that can help with those steps.

Repo: https://github.com/eihli/image-table-ocr

Docs & Source: https://eihli.github.io/image-table-ocr/pdf_table_extraction_and_ocr.html

Some of the steps don't require code, they take advantage of external tools like pdfimages and tesseract. I'll provide some brief examples for a couple of the steps that do require code.

2. Finding tables:

This link was a good reference while figuring out how to find tables. https://answers.opencv.org/question/63847/how-to-extract-tables-from-an-image/

import cv2

def find_tables(image):
    BLUR_KERNEL_SIZE = (17, 17)
    STD_DEV_X_DIRECTION = 0
    STD_DEV_Y_DIRECTION = 0
    blurred = cv2.GaussianBlur(image, BLUR_KERNEL_SIZE, STD_DEV_X_DIRECTION, STD_DEV_Y_DIRECTION)
    MAX_COLOR_VAL = 255
    BLOCK_SIZE = 15
    SUBTRACT_FROM_MEAN = -2

    img_bin = cv2.adaptiveThreshold(
        ~blurred,
        MAX_COLOR_VAL,
        cv2.ADAPTIVE_THRESH_MEAN_C,
        cv2.THRESH_BINARY,
        BLOCK_SIZE,
        SUBTRACT_FROM_MEAN,
    )
    vertical = horizontal = img_bin.copy()
    SCALE = 5
    image_width, image_height = horizontal.shape
    horizontal_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (int(image_width / SCALE), 1))
    horizontally_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, horizontal_kernel)
    vertical_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (1, int(image_height / SCALE)))
    vertically_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, vertical_kernel)

    horizontally_dilated = cv2.dilate(horizontally_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (40, 1)))
    vertically_dilated = cv2.dilate(vertically_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (1, 60)))

    mask = horizontally_dilated + vertically_dilated
    contours, hierarchy = cv2.findContours(
        mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE,
    )

    MIN_TABLE_AREA = 1e5
    contours = [c for c in contours if cv2.contourArea(c) > MIN_TABLE_AREA]
    perimeter_lengths = [cv2.arcLength(c, True) for c in contours]
    epsilons = [0.1 * p for p in perimeter_lengths]
    approx_polys = [cv2.approxPolyDP(c, e, True) for c, e in zip(contours, epsilons)]
    bounding_rects = [cv2.boundingRect(a) for a in approx_polys]

    # The link where a lot of this code was borrowed from recommends an
    # additional step to check the number of "joints" inside this bounding rectangle.
    # A table should have a lot of intersections. We might have a rectangular image
    # here though which would only have 4 intersections, 1 at each corner.
    # Leaving that step as a future TODO if it is ever necessary.
    images = [image[y:y+h, x:x+w] for x, y, w, h in bounding_rects]
    return images

3. Extract cells from table.

This is very similar to 2, so I won't include all the code. The part I will reference will be in sorting the cells.

We want to identify the cells from left-to-right, top-to-bottom.

We’ll find the rectangle with the most top-left corner. Then we’ll find all of the rectangles that have a center that is within the top-y and bottom-y values of that top-left rectangle. Then we’ll sort those rectangles by the x value of their center. We’ll remove those rectangles from the list and repeat.

def cell_in_same_row(c1, c2):
    c1_center = c1[1] + c1[3] - c1[3] / 2
    c2_bottom = c2[1] + c2[3]
    c2_top = c2[1]
    return c2_top < c1_center < c2_bottom

orig_cells = [c for c in cells]
rows = []
while cells:
    first = cells[0]
    rest = cells[1:]
    cells_in_same_row = sorted(
        [
            c for c in rest
            if cell_in_same_row(c, first)
        ],
        key=lambda c: c[0]
    )

    row_cells = sorted([first] + cells_in_same_row, key=lambda c: c[0])
    rows.append(row_cells)
    cells = [
        c for c in rest
        if not cell_in_same_row(c, first)
    ]

# Sort rows by average height of their center.
def avg_height_of_center(row):
    centers = [y + h - h / 2 for x, y, w, h in row]
    return sum(centers) / len(centers)

rows.sort(key=avg_height_of_center)

You don't need to set name , just giving an id is enough.

<input type="hidden" id="testId" />

and than with jquery you can use 'val()' method like below:

 $('#testId').val("work");

AskTom is probably the single most helpful resource on best practices on Oracle DBs. (I usually just type "asktom" as the first word of a google query on a particular topic)

I don't think it's really appropriate to speak of design patterns with relational databases. Relational databases are already the application of a "design pattern" to a problem (the problem being "how to represent, store and work with data while maintaining its integrity", and the design being the relational model). Other approches (generally considered obsolete) are the Navigational and Hierarchical models (and I'm nure many others exist).

Having said that, you might consider "Data Warehousing" as a somewhat separate "pattern" or approach in database design. In particular, you might be interested in reading about the Star schema.

Content-Type: application/json is just the content header. The content header is just information about the type of returned data, ex::JSON,image(png,jpg,etc..),html.

Keep in mind, that JSON in JavaScript is an array or object. If you want to see all the data, use console.log instead of alert:

alert(response.text); // Will alert "[object Object]" string
console.log(response.text); // Will log all data objects

If you want to alert the original JSON content as a string, then add single quotation marks ('):

echo "'" . json_encode(array('text' => 'omrele')) . "'";
// alert(response.text) will alert {"text":"omrele"}

Do not use double quotes. It will confuse JavaScript, because JSON uses double quotes on each value and key:

echo '<script>var returndata=';
echo '"' . json_encode(array('text' => 'omrele')) . '"';
echo ';</script>';

// It will return the wrong JavaScript code:
<script>var returndata="{"text":"omrele"}";</script>

On my Windows 7 machine I have the following environment variables:

• JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07

• M2_HOME=C:\apache-maven-3.0.3

On my PATH variable, I have (among others) the following:

• %JAVA_HOME%\bin;%M2_HOME%\bin

I tried doing what you've done with %M2% having the nested %M2_HOME% and it also works.

If you use read_excel() on a file opened using the function open(), make sure to add rb to the open function to avoid encoding errors

I have used YouTube thumbnails in this way:

$url = 'http://img.youtube.com/vi/' . $youtubeId . '/0.jpg';
$img = dirname(__FILE__) . '/youtubeThumbnail_'  . $youtubeId . '.jpg';
file_put_contents($img, file_get_contents($url));

Remember YouTube prevents to include images directly from their server.

I specify the name by defining inside the VagrantFile and also specify the hostname so i enjoy seeing the name of my project while executing Linux commands independently from my device's OS. ??

config.vm.define "abc"
config.vm.hostname = "abc"

Issue the following command to reseed mytable to start at 1:

DBCC CHECKIDENT (mytable, RESEED, 0)

Read about it in the Books on Line (BOL, SQL help). Also be careful that you don't have records higher than the seed you are setting.

Extension class:

using System.IO;
using System.Xml;
using System.Xml.Serialization;

namespace MyProj.Extensions
{
    public static class XmlExtension
    {
        public static string Serialize<T>(this T value)
        {
            if (value == null) return string.Empty;

            var xmlSerializer = new XmlSerializer(typeof(T));

            using (var stringWriter = new StringWriter())
            {
                using (var xmlWriter = XmlWriter.Create(stringWriter,new XmlWriterSettings{Indent = true}))
                {
                    xmlSerializer.Serialize(xmlWriter, value);
                    return stringWriter.ToString();
                }    
            }
        }
    }
}

Usage:

Foo foo = new Foo{MyProperty="I have been serialized"};

string xml = foo.Serialize();

Just reference the namespace holding your extension method in the file you would like to use it in and it'll work (in my example it would be: using MyProj.Extensions;)

Note that if you want to make the extension method specific to only a particular class(eg., Foo), you can replace the T argument in the extension method, eg.

public static string Serialize(this Foo value){...}

<?php
function info($name="George",$age=18) {
echo "$name is $age years old.<br>";
}
info();     // prints default values(number of values = 2)
info("Nick");   // changes first default argument from George to Nick
info("Mark",17);    // changes both default arguments' values

?>

An option for your application would be to write a replacement Home Screen using the android.intent.category.HOME Intent. I believe this type of Intent you can see the home button.

More details:

CSS3 flexbox can also be used to align button at the bottom of parent element.

How does it work?

When a JSF view (Facelets/JSP file) get built/restored, a JSF component tree will be produced. At that moment, the view build time, all binding attributes are evaluated (along with id attribtues and taghandlers like JSTL). When the JSF component needs to be created before being added to the component tree, JSF will check if the binding attribute returns a precreated component (i.e. non-null) and if so, then use it. If it's not precreated, then JSF will autocreate the component "the usual way" and invoke the setter behind binding attribute with the autocreated component instance as argument.

In effects, it binds a reference of the component instance in the component tree to a scoped variable. This information is in no way visible in the generated HTML representation of the component itself. This information is in no means relevant to the generated HTML output anyway. When the form is submitted and the view is restored, the JSF component tree is just rebuilt from scratch and all binding attributes will just be re-evaluated like described in above paragraph. After the component tree is recreated, JSF will restore the JSF view state into the component tree.

Component instances are request scoped!

Important to know and understand is that the concrete component instances are effectively request scoped. They're newly created on every request and their properties are filled with values from JSF view state during restore view phase. So, if you bind the component to a property of a backing bean, then the backing bean should absolutely not be in a broader scope than the request scope. See also JSF 2.0 specitication chapter 3.1.5:

3.1.5 Component Bindings

...

Component bindings are often used in conjunction with JavaBeans that are dynamically instantiated via the Managed Bean Creation facility (see Section 5.8.1 “VariableResolver and the Default VariableResolver”). It is strongly recommend that application developers place managed beans that are pointed at by component binding expressions in “request” scope. This is because placing it in session or application scope would require thread-safety, since UIComponent instances depends on running inside of a single thread. There are also potentially negative impacts on memory management when placing a component binding in “session” scope.

Otherwise, component instances are shared among multiple requests, possibly resulting in "duplicate component ID" errors and "weird" behaviors because validators, converters and listeners declared in the view are re-attached to the existing component instance from previous request(s). The symptoms are clear: they are executed multiple times, one time more with each request within the same scope as the component is been bound to.

And, under heavy load (i.e. when multiple different HTTP requests (threads) access and manipulate the very same component instance at the same time), you may face sooner or later an application crash with e.g. Stuck thread at UIComponent.popComponentFromEL, or Java Threads at 100% CPU utilization using richfaces UIDataAdaptorBase and its internal HashMap, or even some "strange" IndexOutOfBoundsException or ConcurrentModificationException coming straight from JSF implementation source code while JSF is busy saving or restoring the view state (i.e. the stack trace indicates saveState() or restoreState() methods and like).

Using binding on a bean property is bad practice

Regardless, using binding this way, binding a whole component instance to a bean property, even on a request scoped bean, is in JSF 2.x a rather rare use case and generally not the best practice. It indicates a design smell. You normally declare components in the view side and bind their runtime attributes like value, and perhaps others like styleClass, disabled, rendered, etc, to normal bean properties. Then, you just manipulate exactly that bean property you want instead of grabbing the whole component and calling the setter method associated with the attribute.

In cases when a component needs to be "dynamically built" based on a static model, better is to use view build time tags like JSTL, if necessary in a tag file, instead of createComponent(), new SomeComponent(), getChildren().add() and what not. See also How to refactor snippet of old JSP to some JSF equivalent?

Or, if a component needs to be "dynamically rendered" based on a dynamic model, then just use an iterator component (<ui:repeat>, <h:dataTable>, etc). See also How to dynamically add JSF components.

Composite components is a completely different story. It's completely legit to bind components inside a <cc:implementation> to the backing component (i.e. the component identified by <cc:interface componentType>. See also a.o. Split java.util.Date over two h:inputText fields representing hour and minute with f:convertDateTime and How to implement a dynamic list with a JSF 2.0 Composite Component?

Only use binding in local scope

However, sometimes you'd like to know about the state of a different component from inside a particular component, more than often in use cases related to action/value dependent validation. For that, the binding attribute can be used, but not in combination with a bean property. You can just specify an in the local EL scope unique variable name in the binding attribute like so binding="#{foo}" and the component is during render response elsewhere in the same view directly as UIComponent reference available by #{foo}. Here are several related questions where such a solution is been used in the answer:

• Validate input as required only if certain command button is pressed
• How to render a component only if another component is not rendered?
• JSF 2 dataTable row index without dataModel
• Primefaces dependent selectOneMenu and required="true"
• Validate a group of fields as required when at least one of them is filled
• How to change css class for the inputfield and label when validation fails?

• Use an EL expression to pass a component ID to a composite component in JSF

Strange, but the accepted answer seems wrong about the cast and the Convert in the mean that from my tests and reading the documentation too it should not take into account implicit or explicit operators.

So, if I have a variable of type object and the "boxed" class has some implicit operators defined they won't work.

Instead another simple way, but really performance costing is to cast before in dynamic.

(int)(dynamic)myObject.

You can try it in the Interactive window of VS.

public class Test
{
  public static implicit operator int(Test v)
  {
    return 12;
  }
}

(int)(object)new Test() //this will fail
Convert.ToInt32((object)new Test()) //this will fail
(int)(dynamic)(object)new Test() //this will pass

The problem is likely to lie with the line:

window.onload = onPageLoad();

By including the brackets you are saying onload should equal the return value of onPageLoad(). For example:

/*Example function*/
function onPageLoad()
{
    return "science";
}
/*Set on load*/
window.onload = onPageLoad()

If you print out the value of window.onload to the console it will be:

science

The solution is remove the brackets:

window.onload = onPageLoad;

So, you're using onPageLoad as a reference to the so-named function.

Finally, in order to get the response value you'll need a readystatechange listener for your XMLHttpRequest object, since it's asynchronous:

xmlDoc = xmlhttp.responseXML;
parser = new DOMParser(); // This code is untested as it doesn't run this far.

Here you add the listener:

xmlHttp.onreadystatechange = function() {
    if(this.readyState == 4) {
        // Do something
    }
}

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

I prefer to work with the PSDrive WSMan:\.

Get TrustedHosts

provide a single, comma-separated, string of computer names

Set-Item WSMan:\localhost\Client\TrustedHosts -Value 'machineA,machineB'

or (dangerous) a wild-card

Set-Item WSMan:\localhost\Client\TrustedHosts -Value '*'

to append to the list, the -Concatenate parameter can be used

Set-Item WSMan:\localhost\Client\TrustedHosts -Value 'machineC' -Concatenate

DEMO

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

Without sharex=True, sharey=True you get:

With it you should get it nicer:

fig, axes2d = plt.subplots(nrows=3, ncols=3,
                           sharex=True, sharey=True,
                           figsize=(6,6))

for i, row in enumerate(axes2d):
    for j, cell in enumerate(row):
        cell.imshow(np.random.rand(32,32))

plt.tight_layout()

But if you want to add additional labels, you should add them only to the edge plots:

fig, axes2d = plt.subplots(nrows=3, ncols=3,
                           sharex=True, sharey=True,
                           figsize=(6,6))

for i, row in enumerate(axes2d):
    for j, cell in enumerate(row):
        cell.imshow(np.random.rand(32,32))
        if i == len(axes2d) - 1:
            cell.set_xlabel("noise column: {0:d}".format(j + 1))
        if j == 0:
            cell.set_ylabel("noise row: {0:d}".format(i + 1))

plt.tight_layout()

Adding label for each plot would spoil it (maybe there is a way to automatically detect repeated labels, but I am not aware of one).

you can save the model in json and weights in a hdf5 file format.

# keras library import  for Saving and loading model and weights

from keras.models import model_from_json
from keras.models import load_model

# serialize model to JSON
#  the keras model which is trained is defined as 'model' in this example
model_json = model.to_json()


with open("model_num.json", "w") as json_file:
    json_file.write(model_json)

# serialize weights to HDF5
model.save_weights("model_num.h5")

files "model_num.h5" and "model_num.json" are created which contain our model and weights

To use the same trained model for further testing you can simply load the hdf5 file and use it for the prediction of different data. here's how to load the model from saved files.

# load json and create model
json_file = open('model_num.json', 'r')

loaded_model_json = json_file.read()
json_file.close()
loaded_model = model_from_json(loaded_model_json)

# load weights into new model
loaded_model.load_weights("model_num.h5")
print("Loaded model from disk")

loaded_model.save('model_num.hdf5')
loaded_model=load_model('model_num.hdf5')

To predict for different data you can use this

loaded_model.predict_classes("your_test_data here")

Javascript is pretty good at manipulating css.

 document.body.style.cursor = *cursor-url*;
 //OR
 var elementToChange = document.getElementsByTagName("body")[0];
 elementToChange.style.cursor = "url('cursor url with protocol'), auto";

or with jquery:

$("html").css("cursor: url('cursor url with protocol'), auto");

Firefox will not work unless you specify a default cursor after the imaged one!

other cursor keywords

Also remember that IE6 only supports .cur and .ani cursors.

If cursor doesn't change: In case you are moving the element under the cursor relative to the cursor position (e.g. element dragging) you have to force a redraw on the element:

// in plain js
document.getElementById('parentOfElementToBeRedrawn').style.display = 'none';
document.getElementById('parentOfElementToBeRedrawn').style.display = 'block';
// in jquery
$('#parentOfElementToBeRedrawn').hide().show(0);

working sample:

According to @Shovalt's answer, but in short:

Alternatively you could use the following lines of code

    from sklearn.metrics import f1_score
    metrics.f1_score(y_test, y_pred, labels=np.unique(y_pred))

This should remove your warning and give you the result you wanted, because it no longer considers the difference between the sets, by using the unique mode.

For Mac OSX: There is a way to install Visual Studio Code through Brew-Cask.

1. First, install 'Homebrew' from here.

2. Now run following command and it will install latest Visual Studio Code on your Mac.

   $> brew cask install visual-studio-code

Above command should install Visual Studio Code and also set up the command-line calling of Visual Studio Code.

If above steps don't work then you can do it manually. By following Microsoft Visual Studio Code documentation given here.

Bind & protected-mode both are the essential steps. But if ufw is enabled then you will have to make redis port allow in ufw.

1. Check ufw status ufw status if Status: active then allow redis-port ufw allow 6379
2. vi /etc/redis/redis.conf
3. Change the bind 127.0.0.1 to bind 0.0.0.0
4. change the protected-mode yes to protected-mode no

for me, (OSX) the problem was solved doing this:

brew install pkg-config

You can even use a version range with pip install command. Something like this:

pip install 'stevedore>=1.3.0,<1.4.0'

And if the package is already installed and you want to downgrade it add --force-reinstall like this:

pip install 'stevedore>=1.3.0,<1.4.0' --force-reinstall

Just to add to roya's answer. In c# 6.0 you can now use string interpolation:

Console.WriteLine($"{customer[DisplayPos],10}" +
                  $"{salesFigures[DisplayPos],10}" +
                  $"{feePayable[DisplayPos],10}" +
                  $"{seventyPercentValue,10}" +
                  $"{thirtyPercentValue,10}");

This can actually be one line without all the extra dollars, I just think it makes it a bit easier to read like this.

And you could also use a static import on System.Console, allowing you to do this:

using static System.Console;

WriteLine(/* write stuff */);

I did a quick experiment after looking at a number of potential solutions all over the place. This is what I ended up with:

PHP foreach loop can be used with Indexed arrays, Associative arrays and Object public variables.

In foreach loop, the first thing php does is that it creates a copy of the array which is to be iterated over. PHP then iterates over this new copy of the array rather than the original one. This is demonstrated in the below example:

<?php
$numbers = [1,2,3,4,5,6,7,8,9]; # initial values for our array
echo '<pre>', print_r($numbers, true), '</pre>', '<hr />';
foreach($numbers as $index => $number){
    $numbers[$index] = $number + 1; # this is making changes to the origial array
    echo 'Inside of the array = ', $index, ': ', $number, '<br />'; # showing data from the copied array
}
echo '<hr />', '<pre>', print_r($numbers, true), '</pre>'; # shows the original values (also includes the newly added values).

Besides this, php does allow to use iterated values as a reference to the original array value as well. This is demonstrated below:

<?php
$numbers = [1,2,3,4,5,6,7,8,9];
echo '<pre>', print_r($numbers, true), '</pre>';
foreach($numbers as $index => &$number){
    ++$number; # we are incrementing the original value
    echo 'Inside of the array = ', $index, ': ', $number, '<br />'; # this is showing the original value
}
echo '<hr />';
echo '<pre>', print_r($numbers, true), '</pre>'; # we are again showing the original value

Note: It does not allow original array indexes to be used as references.

According to MSDN, timestamp

Is a data type that exposes automatically generated, unique binary numbers within a database. timestamp is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes. The timestamp data type is just an incrementing number and does not preserve a date or a time. To record a date or time, use a datetime data type.

You're probably looking for the datetime data type instead.

Assuming the changes you want are at the head of the branch you want the changes from, use git checkout

for a single file :

git checkout branch_that_has_the_changes_you_want path/to/file.rb

for multiple files just daisy chain :

git checkout branch_that_has_the_changes_you_want path/to/file.rb path/to/other_file.rb

Is there any 64 bit Visual Studio at all?

Yes literally there is one called "Visual Studio" and is 64bit, but well,, on Mac not on Windows

Why not?

Decision making is electro-chemical reaction made in our brain and that have an activation point (Nerdest answer I can come up with, but follow). Same situation happened in history: Windows 64!...

So in order to answer this fully I want you to remember old days. Imagine reasons for "why not we see 64bit Windows" are there at the time. I think at the time for Windows64 they had exact same reasons others have enlisted here about "reasons why not 64bit VS on windows" were on "reasons why not 64bit Windows" too. Then why they did start development for Windows 64bit? Simple! If they didn't succeed in making 64bit Windows I bet M$ would have been a history nowadays. If same reasons forcing M$ making 64bit Windows starts to appear on need for 64Bit VS then I bet we will see 64bit VS, even though very same reasons everyone else here enlisted will stay same! In time the limitations of 32bit may hit VS as well, so most likely something like below start to happen:

• Visual Studio will drop 32bit support and become 64bit,
• Visual Studio Code will take it's place instead,
• Visual Studio will have similar functionality like WOW64 for old extensions which is I believe unlikely to happen.

I put my bets on Visual Studio Code taking the place in time; I guess bifurcation point for it will be some CPU manufacturer X starts to compete x86_64 architecture taking its place on mainstream market for laptop and/or workstation,

Procedural style :

echo date_format(date_create('17 Oct 2008'), 'c');
// Output : 2008-10-17T00:00:00+02:00

Object oriented style :

$formatteddate = new DateTime('17 Oct 2008');
echo $datetime->format('c');
// Output : 2008-10-17T00:00:00+02:00

Hybrid 1 :

echo date_format(new DateTime('17 Oct 2008'), 'c');
// Output : 2008-10-17T00:00:00+02:00

Hybrid 2 :

echo date_create('17 Oct 2008')->format('c');
// Output : 2008-10-17T00:00:00+02:00

Notes :

1) You could also use 'Y-m-d\TH:i:sP' as an alternative to 'c' for your format.

2) The default time zone of your input is the time zone of your server. If you want the input to be for a different time zone, you need to set your time zone explicitly. This will also impact your output, however :

echo date_format(date_create('17 Oct 2008 +0800'), 'c');
// Output : 2008-10-17T00:00:00+08:00

3) If you want the output to be for a time zone different from that of your input, you can set your time zone explicitly :

echo date_format(date_create('17 Oct 2008')->setTimezone(new DateTimeZone('America/New_York')), 'c');

Your group statement will group by group ID. For example, if you then write:

foreach (var group in groupedCustomerList)
{
    Console.WriteLine("Group {0}", group.Key);
    foreach (var user in group)
    {
        Console.WriteLine("  {0}", user.UserName);
    }
}

that should work fine. Each group has a key, but also contains an IGrouping<TKey, TElement> which is a collection that allows you to iterate over the members of the group. As Lee mentions, you can convert each group to a list if you really want to, but if you're just going to iterate over them as per the code above, there's no real benefit in doing so.

public class ForEachLoopExample {

    public static void main(String[] args) {

        System.out.println("For Each Loop Example: ");

        int[] intArray = { 1,2,3,4,5 };

        //Here iteration starts from index 0 to last index
        for(int i : intArray)
            System.out.println(i);
    }

}

There is only one reason when one needs to pass props to super():

When you want to access this.props in constructor.

Passing:

class MyComponent extends React.Component {    
    constructor(props) {
        super(props)

        console.log(this.props)
        // -> { icon: 'home', … }
    }
}

Not passing:

class MyComponent extends React.Component {    
    constructor(props) {
        super()

        console.log(this.props)
        // -> undefined

        // Props parameter is still available
        console.log(props)
        // -> { icon: 'home', … }
    }

    render() {
        // No difference outside constructor
        console.log(this.props)
        // -> { icon: 'home', … }
    }
}

Note that passing or not passing props to super has no effect on later uses of this.props outside constructor. That is render, shouldComponentUpdate, or event handlers always have access to it.

This is explicitly said in one Sophie Alpert's answer to a similar question.

The documentation—State and Lifecycle, Adding Local State to a Class, point 2—recommends:

Class components should always call the base constructor with props.

However, no reason is provided. We can speculate it is either because of subclassing or for future compatibility.

You can't do this with a UNIQUE constraint, but you can do this in a trigger.

    CREATE TRIGGER [dbo].[OnInsertMyTableTrigger]
   ON  [dbo].[MyTable]
   INSTEAD OF INSERT
AS 
BEGIN
    SET NOCOUNT ON;

    DECLARE @Column1 INT;
    DECLARE @Column2 INT; -- allow nulls on this column

    SELECT @Column1=Column1, @Column2=Column2 FROM inserted;

    -- Check if an existing record already exists, if not allow the insert.
    IF NOT EXISTS(SELECT * FROM dbo.MyTable WHERE Column1=@Column1 AND Column2=@Column2 @Column2 IS NOT NULL)
    BEGIN
        INSERT INTO dbo.MyTable (Column1, Column2)
            SELECT @Column2, @Column2;
    END
    ELSE
    BEGIN
        RAISERROR('The unique constraint applies on Column1 %d, AND Column2 %d, unless Column2 is NULL.', 16, 1, @Column1, @Column2);
        ROLLBACK TRANSACTION;   
    END

END

I like to look at generating passwords, just like generating software keys. You should choose from an array of characters that follow a good practice. Take what @Radu094 answered with and modify it to follow good practice. Don't put every single letter in the character array. Some letters are harder to say or understand over the phone.

You should also consider using a checksum on the password that was generated to make sure that it was generated by you. A good way of accomplishing this is to use the LUHN algorithm.

Why didn't you try to define is_private in your models as default=False?

class Foo(models.Models):
    is_private = models.BooleanField(default=False)

Note: imp is deprecated since Python 3.4 in favor of importlib

As mentioned the imp module provides you loading functions:

imp.load_source(name, path)
imp.load_compiled(name, path)

I've used these before to perform something similar.

In my case I defined a specific class with defined methods that were required. Once I loaded the module I would check if the class was in the module, and then create an instance of that class, something like this:

import imp
import os

def load_from_file(filepath):
    class_inst = None
    expected_class = 'MyClass'

    mod_name,file_ext = os.path.splitext(os.path.split(filepath)[-1])

    if file_ext.lower() == '.py':
        py_mod = imp.load_source(mod_name, filepath)

    elif file_ext.lower() == '.pyc':
        py_mod = imp.load_compiled(mod_name, filepath)

    if hasattr(py_mod, expected_class):
        class_inst = getattr(py_mod, expected_class)()

    return class_inst

To provide numerical values rounded to two decimal places but right-padded with zeros if required I have:

DECLARE @value = 20.1
SET @value = ROUND(@value,2) * 100
PRINT LEFT(CAST(@value AS VARCHAR(20)), LEN(@value)-2) + '.' + RIGHT(CAST(@value AS VARCHAR(20)),2)

If anyone can think of a neater way, that would be appreciated - the above seems clumsy.

Note: in this instance, I'm using SQL Server to email reports in HTML format and so wish to format the information without involving an additional tool to parse the data.

int intVar = (int)ds.Tables[0].Rows[0][n];   // n = column index

float RandomFloat(float min, float max)
{
    float r = (float)rand() / (float)RAND_MAX;
    return min + r * (max - min);
}

You could apply both background-color and border to make it look like 2 colors.

div.A { width: 50px; background-color: #9c9e9f; border-right: 50px solid #f6f6f6; }

The border should have the same size as the width.

use sql server manegement studio or netcat and that will be easier to manipulate sql

Simple

function timeToSeconds($time)
{
     $timeExploded = explode(':', $time);
     if (isset($timeExploded[2])) {
         return $timeExploded[0] * 3600 + $timeExploded[1] * 60 + $timeExploded[2];
     }
     return $timeExploded[0] * 3600 + $timeExploded[1] * 60;
}

I think the solution can be less clunky by using method toISOString(), it has a wide browser compatibility.

So your expression will be a one-liner:

new Date().toISOString().slice(0, 19).replace('T', ' ');

The generated output:

"2017-06-29 17:54:04"

$('.input').keypress(function (e) {
  if (e.which == 13) {
    $('form#login').submit();
    return false;    //<---- Add this line
  }
});

Check out this stackoverflow answer: event.preventDefault() vs. return false

Essentially, "return false" is the same as calling e.preventDefault and e.stopPropagation().

Suppose there are 3 non-negative integers: a, b, and c. Mathematically speaking, if we want to determine if c is between a and b, inclusively, one can use this formula:

(c - a) * (b - c) >= 0

or in Python:

> print((c - a) * (b - c) >= 0)
True

What I use for IsNotNullOrEmptyOrWhiteSpace in T-SQL is:

SELECT [column_name] FROM [table_name]
WHERE LEN(RTRIM(ISNULL([column_name], ''))) > 0

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

For images, you could get the available codecs from GDI (System.Drawing) and build your list from that with a little work. This would be the most flexible way to go.

ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();

I don't know if it's possible but I always pictured myself being able to do this with the CSV storage engine in MySQL. I don't know the details of this engine: http://dev.mysql.com/doc/refman/5.7/en/csv-storage-engine.html but you can look into it and have a file watcher in your operating system that triggers a PHP call if the file is modified.

There are a couple of steps to take:

1. Replace * by . to include hidden files as well.
2. To create the archive in the same directory a --exclude=workspace.tar.gz can be used to exclude the archive itself.
3. To prevent the tar: .: file changed as we read it error when the archive is not yet created, make sure it exists (e.g. using touch), so the --exclude matches with the archive filename. (It does not match it the file does not exists)

Combined this results in the following script:

touch workspace.tar.gz
tar -czf workspace.tar.gz --exclude=workspace.tar.gz .

Annotate class public static void main with, for example: @SpringBootApplication

Yes you can use:

Wsdl2java eclipse plugin

With this all you will need is to supply the wsdl, and the client which is the Java classes will be automatically generated for you.

Microsoft doesn't feel like implementing this useful tool, but if by chance you can have Visual Assist, you have it in VAssistX > Tools > VA Outline. The plugin is not free though.

# To do it for all names
df[] <- lapply( df, factor) # the "[]" keeps the dataframe structure
 col_names <- names(df)
# to do it for some names in a vector named 'col_names'
df[col_names] <- lapply(df[col_names] , factor)

Explanation. All dataframes are lists and the results of [ used with multiple valued arguments are likewise lists, so looping over lists is the task of lapply. The above assignment will create a set of lists that the function data.frame.[<- should successfully stick back into into the dataframe, df

Another strategy would be to convert only those columns where the number of unique items is less than some criterion, let's say fewer than the log of the number of rows as an example:

cols.to.factor <- sapply( df, function(col) length(unique(col)) < log10(length(col)) )
df[ cols.to.factor] <- lapply(df[ cols.to.factor] , factor)

Had the same problem. Unfortunately

dos2unix winfile.sh
bash: dos2unix: command not found

so I did this to convert.

 awk '{ sub("\r$", ""); print }' winfile.sh > unixfile.sh

and then

bash unixfile.sh

I usually start mysql server by typing

$ mysql.server start

without sudo. But in error I type sudo before the command. Now I have to remove the error file to start the server.

$ sudo rm /usr/local/var/mysql/`hostname`.err

To read the result you can read it like a simple php array.

For example, getting the name can be done like $user['name'], and so on. The method fetch(PDO::FETCH_ASSOC) will only return 1 tuple tho. If you want to get all tuples, you can use fetchall(PDO::FETCH_ASSOC). You can go through the multidimensional array and get the values just the same.

The closest thing to renaming is deleting and then re-creating on the remote. For example:

git branch -m master master-old
git push remote :master         # delete master
git push remote master-old      # create master-old on remote

git checkout -b master some-ref # create a new local master
git push remote master          # create master on remote

However this has a lot of caveats. First, no existing checkouts will know about the rename - git does not attempt to track branch renames. If the new master doesn't exist yet, git pull will error out. If the new master has been created. the pull will attempt to merge master and master-old. So it's generally a bad idea unless you have the cooperation of everyone who has checked out the repository previously.

Note: Newer versions of git will not allow you to delete the master branch remotely by default. You can override this by setting the receive.denyDeleteCurrent configuration value to warn or ignore on the remote repository. Otherwise, if you're ready to create a new master right away, skip the git push remote :master step, and pass --force to the git push remote master step. Note that if you're not able to change the remote's configuration, you won't be able to completely delete the master branch!

This caveat only applies to the current branch (usually the master branch); any other branch can be deleted and recreated as above.

For int values:

public static int[] primeFactors(int value) {
    int[] a = new int[31];
    int i = 0, j;
    int num = value;
    while (num % 2 == 0) {
        a[i++] = 2;
        num /= 2;
    }
    j = 3;
    while (j <= Math.sqrt(num) + 1) {
        if (num % j == 0) {
            a[i++] = j;
            num /= j;
        } else {
            j += 2;
        }
    }
    if (num > 1) {
        a[i++] = num;
    }
    int[] b = Arrays.copyOf(a, i);
    return b;
}

For long values:

static long[] getFactors(long value) {
    long[] a = new long[63];
    int i = 0;
    long num = value;
    while (num % 2 == 0) {
        a[i++] = 2;
        num /= 2;
    }
    long j = 3;
    while (j <= Math.sqrt(num) + 1) {
        if (num % j == 0) {
            a[i++] = j;
            num /= j;
        } else {
            j += 2;
        }
    }
    if (num > 1) {
        a[i++] = num;
    }
    long[] b = Arrays.copyOf(a, i);
    return b;
}

Don't use a regex

The expression in the accepted answer misses many cases. Among other things, URLs can have unicode characters in them. The regex you want is here, and after looking at it, you may conclude that you don't really want it after all. The most correct version is ten-thousand characters long.

Admittedly, if you were starting with plain, unstructured text with a bunch of URLs in it, then you might need that ten-thousand-character-long regex. But if your input is structured, use the structure. Your stated aim is to "extract the url, inside the anchor tag's href." Why use a ten-thousand-character-long regex when you can do something much simpler?

Parse the HTML instead

For many tasks, using Beautiful Soup will be far faster and easier to use:

>>> from bs4 import BeautifulSoup as Soup
>>> html = Soup(s, 'html.parser')           # Soup(s, 'lxml') if lxml is installed
>>> [a['href'] for a in html.find_all('a')]
['http://example.com', 'http://example2.com']

If you prefer not to use external tools, you can also directly use Python's own built-in HTML parsing library. Here's a really simple subclass of HTMLParser that does exactly what you want:

from html.parser import HTMLParser

class MyParser(HTMLParser):
    def __init__(self, output_list=None):
        HTMLParser.__init__(self)
        if output_list is None:
            self.output_list = []
        else:
            self.output_list = output_list
    def handle_starttag(self, tag, attrs):
        if tag == 'a':
            self.output_list.append(dict(attrs).get('href'))

Test:

>>> p = MyParser()
>>> p.feed(s)
>>> p.output_list
['http://example.com', 'http://example2.com']

You could even create a new method that accepts a string, calls feed, and returns output_list. This is a vastly more powerful and extensible way than regular expressions to extract information from html.

Change the key of the component.

When a key changes, React will create a new component instance rather than update the current one. Keys are usually used for dynamic lists but are also useful here.

@@ROWCOUNT will give the number of rows affected by the last SQL statement, it is best to capture it into a local variable following the command in question, as its value will change the next time you look at it:

DECLARE @Rows int
DECLARE @TestTable table (col1 int, col2 int)
INSERT INTO @TestTable (col1, col2) select 1,2 union select 3,4
SELECT @Rows=@@ROWCOUNT
SELECT @Rows AS Rows,@@ROWCOUNT AS [ROWCOUNT]

OUTPUT:

(2 row(s) affected)
Rows        ROWCOUNT
----------- -----------
2           1

(1 row(s) affected)

you get Rows value of 2, the number of inserted rows, but ROWCOUNT is 1 because the SELECT @Rows=@@ROWCOUNT command affected 1 row

if you have multiple INSERTs or UPDATEs, etc. in your transaction, you need to determine how you would like to "count" what is going on. You could have a separate total for each table, a single grand total value, or something completely different. You'll need to DECLARE a variable for each total you want to track and add to it following each operation that applies to it:

--note there is no error handling here, as this is a simple example
DECLARE @AppleTotal  int
DECLARE @PeachTotal  int

SELECT @AppleTotal=0,@PeachTotal=0

BEGIN TRANSACTION

INSERT INTO Apple (col1, col2) Select col1,col2 from xyz where ...
SET @AppleTotal=@AppleTotal+@@ROWCOUNT

INSERT INTO Apple (col1, col2) Select col1,col2 from abc where ...
SET @AppleTotal=@AppleTotal+@@ROWCOUNT

INSERT INTO Peach (col1, col2) Select col1,col2 from xyz where ...
SET @PeachTotal=@PeachTotal+@@ROWCOUNT

INSERT INTO Peach (col1, col2) Select col1,col2 from abc where ...
SET @PeachTotal=@PeachTotal+@@ROWCOUNT

COMMIT

SELECT @AppleTotal AS AppleTotal, @PeachTotal AS PeachTotal

For read a cookie i've made little modifications of the Miquel version that doesn't work for me:

getCookie(name: string) {
        let ca: Array<string> = document.cookie.split(';');
        let cookieName = name + "=";
        let c: string;

        for (let i: number = 0; i < ca.length; i += 1) {
            if (ca[i].indexOf(name, 0) > -1) {
                c = ca[i].substring(cookieName.length +1, ca[i].length);
                console.log("valore cookie: " + c);
                return c;
            }
        }
        return "";

For people using Kotlin you can put this in your MainActivity.kt:

window.navigationBarColor = ContextCompat.getColor(this@MainActivity, R.color.yourColor)

With window being:

val window: Window = [email protected]

Or you can put this in your themes.xml or styles.xml (requires API level 21):

<item name='android:navigationBarColor'>@color/yourColor</item>

The documentation in the w3 link

http://www.w3.org/TR/REC-xml/#sec-starttags

says that this are the recomended forms.

<test/>

The attribute mentioned in the other answer is validation mechanism and not a representation of state. Please refer to the http://www.w3.org/TR/xmlschema-1/#xsi_nil

XML Schema: Structures introduces a mechanism for signaling that an element should be accepted as ·valid· when it has no content despite a content type which does not require or even necessarily allow empty content. An element may be ·valid· without content if it has the attribute xsi:nil with the value true. An element so labeled must be empty, but can carry attributes if permitted by the corresponding complex type.

To clarify this answer: Content

  <Book>
    <!--Invalid construct since the element attribute xsi:nil="true" signal that the element must be empty-->
    <BuildAttributes HardCover="true" Glued="true" xsi:nil="true">
      <anotherAttribute name="Color">Blue</anotherAttribute>
    </BuildAttributes>
    <Index></Index>
    <pages>
      <page pageNumber="1">Content</page>            
    </pages>
    <!--Missing ISBN number could be confusing and misguiding since its not present-->
  </Book>
</Books>

I took the liberty of feeding your classes into the CGbR generator. Because it is in an early stage it doesn't support DateTime yet, so I simply replaced it with long. The generated serialization code looks like this:

public int Size
{
    get 
    { 
        var size = 24;
        // Add size for collections and strings
        size += Cts == null ? 0 : Cts.Count * 4;
        size += Tes == null ? 0 : Tes.Count * 4;
        size += Code == null ? 0 : Code.Length;
        size += Message == null ? 0 : Message.Length;

        return size;              
    }
}

public byte[] ToBytes(byte[] bytes, ref int index)
{
    if (index + Size > bytes.Length)
        throw new ArgumentOutOfRangeException("index", "Object does not fit in array");

    // Convert Cts
    // Two bytes length information for each dimension
    GeneratorByteConverter.Include((ushort)(Cts == null ? 0 : Cts.Count), bytes, ref index);
    if (Cts != null)
    {
        for(var i = 0; i < Cts.Count; i++)
        {
            var value = Cts[i];
            value.ToBytes(bytes, ref index);
        }
    }
    // Convert Tes
    // Two bytes length information for each dimension
    GeneratorByteConverter.Include((ushort)(Tes == null ? 0 : Tes.Count), bytes, ref index);
    if (Tes != null)
    {
        for(var i = 0; i < Tes.Count; i++)
        {
            var value = Tes[i];
            value.ToBytes(bytes, ref index);
        }
    }
    // Convert Code
    GeneratorByteConverter.Include(Code, bytes, ref index);
    // Convert Message
    GeneratorByteConverter.Include(Message, bytes, ref index);
    // Convert StartDate
    GeneratorByteConverter.Include(StartDate.ToBinary(), bytes, ref index);
    // Convert EndDate
    GeneratorByteConverter.Include(EndDate.ToBinary(), bytes, ref index);
    return bytes;
}

public Td FromBytes(byte[] bytes, ref int index)
{
    // Read Cts
    var ctsLength = GeneratorByteConverter.ToUInt16(bytes, ref index);
    var tempCts = new List<Ct>(ctsLength);
    for (var i = 0; i < ctsLength; i++)
    {
        var value = new Ct().FromBytes(bytes, ref index);
        tempCts.Add(value);
    }
    Cts = tempCts;
    // Read Tes
    var tesLength = GeneratorByteConverter.ToUInt16(bytes, ref index);
    var tempTes = new List<Te>(tesLength);
    for (var i = 0; i < tesLength; i++)
    {
        var value = new Te().FromBytes(bytes, ref index);
        tempTes.Add(value);
    }
    Tes = tempTes;
    // Read Code
    Code = GeneratorByteConverter.GetString(bytes, ref index);
    // Read Message
    Message = GeneratorByteConverter.GetString(bytes, ref index);
    // Read StartDate
    StartDate = DateTime.FromBinary(GeneratorByteConverter.ToInt64(bytes, ref index));
    // Read EndDate
    EndDate = DateTime.FromBinary(GeneratorByteConverter.ToInt64(bytes, ref index));

    return this;
}

I created a list of sample objects like this:

var objects = new List<Td>();
for (int i = 0; i < 1000; i++)
{
    var obj = new Td
    {
        Message = "Hello my friend",
        Code = "Some code that can be put here",
        StartDate = DateTime.Now.AddDays(-7),
        EndDate = DateTime.Now.AddDays(2),
        Cts = new List<Ct>(),
        Tes = new List<Te>()
    };
    for (int j = 0; j < 10; j++)
    {
        obj.Cts.Add(new Ct { Foo = i * j });
        obj.Tes.Add(new Te { Bar = i + j });
    }
    objects.Add(obj);
}

Results on my machine in Release build:

var watch = new Stopwatch();
watch.Start();
var bytes = BinarySerializer.SerializeMany(objects);
watch.Stop();

Size: 149000 bytes

Time: 2.059ms 3.13ms

Edit: Starting with CGbR 0.4.3 the binary serializer supports DateTime. Unfortunately the DateTime.ToBinary method is insanely slow. I will replace it with somehting faster soon.

Edit2: When using UTC DateTime by invoking ToUniversalTime() the performance is restored and clocks in at 1.669ms.

In case you need to find documents which contain NULL elements inside an array of sub-documents, I've found this query which works pretty well:

db.collection.find({"keyWithArray":{$elemMatch:{"$in":[null], "$exists":true}}})

This query is taken from this post: MongoDb query array with null values

It was a great find and it works much better than my own initial and wrong version (which turned out to work fine only for arrays with one element):

.find({
    'MyArrayOfSubDocuments': { $not: { $size: 0 } },
    'MyArrayOfSubDocuments._id': { $exists: false }
})

In practice, the models are used as follows.

In discriminative models, to predict the label y from the training example x, you must evaluate:

which merely chooses what is the most likely class y considering x. It's like we were trying to model the decision boundary between the classes. This behavior is very clear in neural networks, where the computed weights can be seen as a complexly shaped curve isolating the elements of a class in the space.

Now, using Bayes' rule, let's replace the in the equation by . Since you are just interested in the arg max, you can wipe out the denominator, that will be the same for every y. So, you are left with

which is the equation you use in generative models.

While in the first case you had the conditional probability distribution p(y|x), which modeled the boundary between classes, in the second you had the joint probability distribution p(x, y), since p(x | y) p(y) = p(x, y), which explicitly models the actual distribution of each class.

With the joint probability distribution function, given a y, you can calculate ("generate") its respective x. For this reason, they are called "generative" models.

You can do either, but never both. Usually you do it at function declaration and then all callers can use that default value. However you can do that at function definition instead and then only those who see the definition will be able to use the default value.

node-cron does just what I described

I got it to work by doing this, assuming you are using PDO.

//Place query here, let's say you want all the users that have blue as their favorite color
$sql = "SELECT name FROM user WHERE favorite_color = :color";

//set parameters 
//you may set as many parameters as you have on your query
$params['color'] = blue;


//create the prepared statement, by getting the doctrine connection
$stmt = $this->entityManager->getConnection()->prepare($sql);
$stmt->execute($params);
//I used FETCH_COLUMN because I only needed one Column.
return $stmt->fetchAll(PDO::FETCH_COLUMN);

You can change the FETCH_TYPE to suit your needs.

How to properly ignore Exceptions?

There are several ways of doing this.

However, the choice of example has a simple solution that does not cover the general case.

Specific to the example:

Instead of

try:
    shutil.rmtree(path)
except:
    pass

Do this:

shutil.rmtree(path, ignore_errors=True)

This is an argument specific to shutil.rmtree. You can see the help on it by doing the following, and you'll see it can also allow for functionality on errors as well.

>>> import shutil
>>> help(shutil.rmtree)

Since this only covers the narrow case of the example, I'll further demonstrate how to handle this if those keyword arguments didn't exist.

General approach

Since the above only covers the narrow case of the example, I'll further demonstrate how to handle this if those keyword arguments didn't exist.

New in Python 3.4:

You can import the suppress context manager:

from contextlib import suppress

But only suppress the most specific exception:

with suppress(FileNotFoundError):
    shutil.rmtree(path)

You will silently ignore a FileNotFoundError:

>>> with suppress(FileNotFoundError):
...     shutil.rmtree('bajkjbkdlsjfljsf')
... 
>>> 

From the docs:

As with any other mechanism that completely suppresses exceptions, this context manager should be used only to cover very specific errors where silently continuing with program execution is known to be the right thing to do.

Note that suppress and FileNotFoundError are only available in Python 3.

If you want your code to work in Python 2 as well, see the next section:

Python 2 & 3:

When you just want to do a try/except without handling the exception, how do you do it in Python?

Is the following the right way to do it?

try :
    shutil.rmtree ( path )
except :
    pass

For Python 2 compatible code, pass is the correct way to have a statement that's a no-op. But when you do a bare except:, that's the same as doing except BaseException: which includes GeneratorExit, KeyboardInterrupt, and SystemExit, and in general, you don't want to catch those things.

In fact, you should be as specific in naming the exception as you can.

Here's part of the Python (2) exception hierarchy, and as you can see, if you catch more general Exceptions, you can hide problems you did not expect:

BaseException
 +-- SystemExit
 +-- KeyboardInterrupt
 +-- GeneratorExit
 +-- Exception
      +-- StopIteration
      +-- StandardError
      |    +-- BufferError
      |    +-- ArithmeticError
      |    |    +-- FloatingPointError
      |    |    +-- OverflowError
      |    |    +-- ZeroDivisionError
      |    +-- AssertionError
      |    +-- AttributeError
      |    +-- EnvironmentError
      |    |    +-- IOError
      |    |    +-- OSError
      |    |         +-- WindowsError (Windows)
      |    |         +-- VMSError (VMS)
      |    +-- EOFError
... and so on

You probably want to catch an OSError here, and maybe the exception you don't care about is if there is no directory.

We can get that specific error number from the errno library, and reraise if we don't have that:

import errno

try:
    shutil.rmtree(path)
except OSError as error:
    if error.errno == errno.ENOENT: # no such file or directory
        pass
    else: # we had an OSError we didn't expect, so reraise it
        raise 

Note, a bare raise raises the original exception, which is probably what you want in this case. Written more concisely, as we don't really need to explicitly pass with code in the exception handling:

try:
    shutil.rmtree(path)
except OSError as error:
    if error.errno != errno.ENOENT: # no such file or directory
        raise 

I had similar issue when connecting to RDS Oracle even when client and server were both set to TLSv1.2 the certs was right and java was 1.8.0_141 So Finally I had to apply patch at Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files

After applying the patch the issue went away and connection went fine.

You could use JSON.stringify(array) to encode your array in JavaScript, and then use $array=json_decode($_POST['jsondata']); in your PHP script to retrieve it.

I have on several projects.

The biggest difference in my opinion

• jQuery UI is fallback safe, it works correctly and looks good in old browsers, where Bootstrap is based on CSS3 which basically means GREAT in new browsers, not so great in old

• Update frequency: Bootstrap is getting some great big updates with awesome new features, but sadly they might break previous code, so you can't just install bootstrap and update when there is a new major release, it basically requires a lot of new coding

• jQuery UI is based on good html structure with transformations from JavaScript, while Bootstrap is based on visually and customizable inline structure. (calling a widget in JQUERY UI, defining it in Bootstrap)

So what to choose?

That always depends on the type of project you are working on. Is cool and fast looking widgets better, or are your users often using old browsers?

I always end up using both, so I can use the best of both worlds.

Here are the links to both frameworks, if you decide to use them.

1. jQuery UI
2. Bootstrap

Here's also nice way to achieve this via UI.

meshgrid helps in creating a rectangular grid from two 1-D arrays of all pairs of points from the two arrays.

x = np.array([0, 1, 2, 3, 4])
y = np.array([0, 1, 2, 3, 4])

Now, if you have defined a function f(x,y) and you wanna apply this function to all the possible combination of points from the arrays 'x' and 'y', then you can do this:

f(*np.meshgrid(x, y))

Say, if your function just produces the product of two elements, then this is how a cartesian product can be achieved, efficiently for large arrays.

Rights

Keep in mind that you will need the appropriate rights. The permissions are called "Undo other users' changes" and "Unlock other users' changes". These permissions can be viewed by:

1. Right-clicking the desired project, folder, or file in Source Control Explorer
2. Select Properties
3. Select the Security tab
4. Select the appropriate user or group in the Users and Groups section at the top
5. View the "Permissions for [user/group]:" section at the bottom

Faster way to create folder:

if (!is_dir('path/to/directory')) {
    mkdir('path/to/directory', 0777, true);
}

Your example code is wrong. This works:

import datetime

datetime.datetime.strptime("21/12/2008", "%d/%m/%Y").strftime("%Y-%m-%d")

The call to strptime() parses the first argument according to the format specified in the second, so those two need to match. Then you can call strftime() to format the result into the desired final format.

The type of expression

" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'"

is std::string. However function system has declaration

int system(const char *s);

that is it accepts an argumnet of type const char *

There is no conversion operator that would convert implicitly an object of type std::string to object of type const char *.

Nevertheless class std::string has two functions that do this conversion explicitly. They are c_str() and data() (the last can be used only with compiler that supports C++11)

So you can write

string name = "john";

system( (" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str() );

There is no need to use an intermediate variable for the expression.

The common practice nowadays is to generate a content hash code as part of the file name to force the browser especially IE to reload the javascript files or css files.

For example,

vendor.a7561fb0e9a071baadb9.js

It is generally the job for the build tools such as webpack. Here is more details if anyone wants to try out if you are using webpack.

On ASP.net web forms use in the @page AspCompat="true", add the system.windows.forms to you project. At your web.config add:

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="false" />
  </appSettings>

Then you can use:

Clipboard.SetText(CreateDescription());

When embedding same-origin SVGs using <object>, you can access the internal contents using objectElement.contentDocument.rootElement. From there, you can easily attach event handlers (e.g. via onclick, addEventListener(), etc.)

For example:

var object = /* get DOM node for <object> */;
var svg = object.contentDocument.rootElement;
svg.addEventListener('click', function() {
  console.log('hooray!');
});

Note that this is not possible for cross-origin <object> elements unless you also control the <object> origin server and can set CORS headers there. For cross-origin cases without CORS headers, access to contentDocument is blocked.

I am using this method to implement the same thing, but for some reason I am getting an exception on the ReadObject method: "Expecting element 'root' from namespace ''.. Encountered 'None' with name '', namespace ''." Any ideas why? – Dan Appleyard Apr 6 '10 at 17:57

I had the same problem (MVC 3 build 3.0.11209.0), and the post below solved it for me. Basically the json serializer is trying to read a stream which is not at the beginning, so repositioning the stream to 0 'fixed' it...

It depends on what type of fading you are looking for.

But with shadow and rounded corners you can get a nice result. Rounded corners because the bigger the shadow, the weirder it will look in the edges unless you balance it out with rounded corners.

You seem to be unnecessarily setting properties on your ComboBox. You can remove the DisplayMemberPath and SelectedValuePath properties which have different uses. It might be an idea for you to take a look at the Difference between SelectedItem, SelectedValue and SelectedValuePath post here for an explanation of these properties. Try this:

<ComboBox Name="cbxSalesPeriods"
    ItemsSource="{Binding SalesPeriods}"
    SelectedItem="{Binding SelectedSalesPeriod}"
    IsSynchronizedWithCurrentItem="True"/>

Furthermore, it is pointless using your displayPeriod property, as the WPF Framework would call the ToString method automatically for objects that it needs to display that don't have a DataTemplate set up for them explicitly.

UPDATE >>>

As I can't see all of your code, I cannot tell you what you are doing wrong. Instead, all I can do is to provide you with a complete working example of how to achieve what you want. I've removed the pointless displayPeriod property and also your SalesPeriodVO property from your class as I know nothing about it... maybe that is the cause of your problem??. Try this:

public class SalesPeriodV
{
    private int month, year;

    public int Year
    {
        get { return year; }
        set
        {
            if (year != value)
            {
                year = value;
                NotifyPropertyChanged("Year");
            }
        }
    }

    public int Month
    {
        get { return month; }
        set
        {
            if (month != value)
            {
                month = value;
                NotifyPropertyChanged("Month");
            }
        }
    }

    public override string ToString()
    {
        return String.Format("{0:D2}.{1}", Month, Year);
    }

    public virtual event PropertyChangedEventHandler PropertyChanged;
    protected virtual void NotifyPropertyChanged(params string[] propertyNames)
    {
        if (PropertyChanged != null)
        {
            foreach (string propertyName in propertyNames) PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            PropertyChanged(this, new PropertyChangedEventArgs("HasError"));
        }
    }
}

Then I added two properties into the view model:

private ObservableCollection<SalesPeriodV> salesPeriods = new ObservableCollection<SalesPeriodV>();
public ObservableCollection<SalesPeriodV> SalesPeriods
{
    get { return salesPeriods; }
    set { salesPeriods = value; NotifyPropertyChanged("SalesPeriods"); }
}
private SalesPeriodV selectedItem = new SalesPeriodV();
public SalesPeriodV SelectedItem
{
    get { return selectedItem; }
    set { selectedItem = value; NotifyPropertyChanged("SelectedItem"); }
}

Then initialised the collection with your values:

SalesPeriods.Add(new SalesPeriodV() { Month = 3, Year = 2013 } );
SalesPeriods.Add(new SalesPeriodV() { Month = 4, Year = 2013 } );

And then data bound only these two properties to a ComboBox:

<ComboBox ItemsSource="{Binding SalesPeriods}" SelectedItem="{Binding SelectedItem}" />

That's it... that's all you need for a perfectly working example. You should see that the display of the items comes from the ToString method without your displayPeriod property. Hopefully, you can work out your mistakes from this code example.

Create epoll object,
open many client TCP sockets,
adjust their send buffers to be a bit more than request header,
send a request header — it should be immediate, just placing into a buffer, register socket in epoll object,
do .poll on epoll obect,
read first 3 bytes from each socket from .poll,
write them to sys.stdout followed by \n (don't flush), close the client socket.

Limit number of sockets opened simultaneously — handle errors when sockets are created. Create a new socket only if another is closed.
Adjust OS limits.
Try forking into a few (not many) processes: this may help to use CPU a bit more effectively.

The above code is when we are setting the elements value in the list as per user requirements. And below code is as per the question asked

#find the highest element in the list
high = max(numbers)
#find the lowest element in the list
secondhigh = min(numbers)
for x in numbers:
    '''
    find the second highest element in the list,
    it works even when there are duplicates highest element in the list.
    It runs through the entire list finding the next lowest element
    which is less then highest element but greater than lowest element in
    the list set initially. And assign that value to secondhigh variable, so 
    now this variable will have next lowest element in the list. And by end 
    of loop it will have the second highest element in the list  
    '''
    if (x<high and x>secondhigh):
        secondhigh=x
print(secondhigh)

The amount of hacks you would need to go through to completely hide the fact your site is built by Meteor.js is absolutely ridiculous. You would have to strip essentially all core functionality and just serve straight up html, completely defeating the purpose of using the framework anyway.

That being said, I suggest looking at buildwith.com

You enter a url, and it reveals a ton of information about a site. If you only need to "fool" engines like this, there may be simple solutions.

Here is an overlay using a pseudo-element (eg: no need to add more markup to do it)

.box {_x000D_
  background: 0 0 url(http://ianfarb.com/wp-content/uploads/2013/10/nicholas-hodag.jpg);_x000D_
  width: 300px;_x000D_

  display: block;_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  background: rgba(0, 0, 0, 0.4);_x000D_
}

  <div class="box"></div>

Try this:

string command = "...";
var process = Process.Start(command);
process.WaitForExit();

Just to add to the other answers, the documentation gives this explanation:

• KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

• A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. For all engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL.

• A PRIMARY KEY is a unique index where all key columns must be defined as NOT NULL. If they are not explicitly declared as NOT NULL, MySQL declares them so implicitly (and silently). A table can have only one PRIMARY KEY. The name of a PRIMARY KEY is always PRIMARY, which thus cannot be used as the name for any other kind of index.

SHA1 is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do.

However, breaking a SHA1 hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that's pretty much the only way.

So to answer your question: yes, it is possible, but you need significant computing power. Some researchers estimate that it costs $70k - $120k.

As far as we can tell today, there is also no other way but to guess the hashed input. This is because operations such as mod eliminate information from your input. Suppose you calculate mod 5 and you get 0. What was the input? Was it 0, 5 or 500? You see, you can't really 'go back' in this case.

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

I use a hash and a salt for my password encryption (it's the same hash that Asp.Net Membership uses):

private string PasswordSalt
{
   get
   {
      var rng = new RNGCryptoServiceProvider();
      var buff = new byte[32];
      rng.GetBytes(buff);
      return Convert.ToBase64String(buff);
   }
}

private string EncodePassword(string password, string salt)
{
   byte[] bytes = Encoding.Unicode.GetBytes(password);
   byte[] src = Encoding.Unicode.GetBytes(salt);
   byte[] dst = new byte[src.Length + bytes.Length];
   Buffer.BlockCopy(src, 0, dst, 0, src.Length);
   Buffer.BlockCopy(bytes, 0, dst, src.Length, bytes.Length);
   HashAlgorithm algorithm = HashAlgorithm.Create("SHA1");
   byte[] inarray = algorithm.ComputeHash(dst);
   return Convert.ToBase64String(inarray);
}

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
    function($scope, Global, Dashboard) {
        $scope.global = Global;
        $scope.package = {
            name: 'dashboard'
        };
        // ...
    }
]);

app.run(function(editableOptions) {
    editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});

For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar's excellent link for such tools). However, up to this day, there is no decompiler for native code. I'm not aware of anything similar for other high-level languages either.

This answer is similar to @PaulMcG's answer but doesn't require sorting the input.

For those into functional programming, groupBy can be written in one line (not including imports!), and unlike itertools.groupby it doesn't require the input to be sorted:

from functools import reduce # import needed for python3; builtin in python2
from collections import defaultdict

def groupBy(key, seq):
 return reduce(lambda grp, val: grp[key(val)].append(val) or grp, seq, defaultdict(list))

(The reason for ... or grp in the lambda is that for this reduce() to work, the lambda needs to return its first argument; because list.append() always returns None the or will always return grp. I.e. it's a hack to get around python's restriction that a lambda can only evaluate a single expression.)

This returns a dict whose keys are found by evaluating the given function and whose values are a list of the original items in the original order. For the OP's example, calling this as groupBy(lambda pair: pair[1], input) will return this dict:

{'KAT': [('11013331', 'KAT'), ('9843236', 'KAT')],
 'NOT': [('9085267', 'NOT'), ('11788544', 'NOT')],
 'ETH': [('5238761', 'ETH'), ('5349618', 'ETH'), ('962142', 'ETH'), ('7795297', 'ETH'), ('7341464', 'ETH'), ('5594916', 'ETH'), ('1550003', 'ETH')]}

And as per @PaulMcG's answer the OP's requested format can be found by wrapping that in a list comprehension. So this will do it:

result = {key: [pair[0] for pair in values],
          for key, values in groupBy(lambda pair: pair[1], input).items()}

It seems that for ignoring files and directories there are two main ways:

1. .gitignore

   • Placing .gitignore file into the root of your repository besides the .git folder (in Windows, make sure you see the true file extension and then make .gitignore. (with the point at the end to make an empty file extension))
   • Making the global configuration ~/.gitignore_global and running git config --global core.excludesfile ~/.gitignore_global to add this to your Git configuration

   Note: files tracked before can be untracked by running git rm --cached filename

2. Repository exclude - For local files that do not need to be shared, you just add the file pattern or directory to the file .git/info/exclude. Theses rules are not committed, so they are not seen by other users. More information is here.

To make exceptions in the list of ignored files, see this question.

you could also try: instance_of?

p 1.instance_of? Fixnum    #=> True
p "1".instance_of? String  #=> True
p [1,2].instance_of? Array #=> True

To answer your question, these should work as long as:

• Your HTTP server passes these values along to PHP (I don't know any that don't)
• You're not accessing the script via command line (CLI)

But, if I remember correctly, these values can be faked to an extent, so it's best not to rely on them.

My personal preference is to set the domain name as an environment variable in the apache2 virtual host:

# Virtual host
setEnv DOMAIN_NAME example.com

And read it in PHP:

// PHP
echo getenv(DOMAIN_NAME);

This, however, isn't applicable in all circumstances.

                            System.out.println(" Test2 - ");
                            return true; // File not exists
                    }

I think you're looking for this:

Another thing to be careful of (I did this so I know, duh). Be sure not to enable Proguard for debug!

First of all, you need to check that the IIS is installed in your machine, for that you can go to:

Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'

If not, check it, and Press Accept to install it.

Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).

Edit: You should have something like this:

import time
time.strftime('%H:%M%p %Z on %b %d, %Y')

This may come in handy

YaLinqo library* is well suited for this sort of task. It's a port of LINQ from .NET which fully supports values and keys in all callbacks and resembles SQL. For example:

$mapped_array = from($test_array)
    ->select(function ($v, $k) { return "$k loves $v"; })
    ->toArray();

or just:

$mapped_iterator = from($test_array)->select('"$k loves $v"');

Here, '"$k loves $v"' is a shortcut for full closure syntax which this library supports. toArray() in the end is optional. The method chain returns an iterator, so if the result just needs to be iterated over using foreach, toArray call can be removed.

git stash drop takes no parameter - which drops the top stash - or a stash reference which looks like: stash@{n} which n nominates which stash to drop. You can't pass a commit id to git stash drop.

git stash drop            # drop top hash, stash@{0}
git stash drop stash@{n}  # drop specific stash - see git stash list

Dropping a stash will change the stash@{n} designations of all stashes further down the stack.

I'm not sure why you think need to drop a stash because if you are using stash create a stash entry isn't created for your "stash" so there isn't anything to drop.

If you're running these commands in a Docker container on Windows, it may mean that your docker machine's network connection is stale and needs to be rebuilt. To fix it, run these commands:

docker-machine stop
docker-machine start
@FOR /f "tokens=*" %i IN ('docker-machine env') DO @%i

This error also occurs if you did not upload the various rsl/swc/flash-library that your swf file might expect. You may upload this RSL or missing swc or tweak your compiler options cf. http://help.adobe.com/en_US/flashbuilder/using/WSe4e4b720da9dedb5-1a92eab212e75b9d8b2-7ffe.html#WSe4e4b720da9dedb5-1a92eab212e75b9d8b2-7ff5

DISTINCT is always a right choice to get unique values. Also you can do it alternatively without using it. That's GROUP BY. Which has simply add at the end of the query and followed by the column name.

I found the following solution to be easiest to setup environment variable for Webpack 2:

For example we have a webpack settings:

var webpack = require('webpack')

let webpackConfig = (env) => { // Passing envirmonment through
                                // function is important here
    return {
        entry: {
        // entries
        },

        output: {
        // outputs
        },

        plugins: [
        // plugins
        ],

        module: {
        // modules
        },

        resolve: {
        // resolves
        }

    }
};

module.exports = webpackConfig;

Add Environment Variable in Webpack:

plugins: [
    new webpack.EnvironmentPlugin({
       NODE_ENV: 'development',
       }),
]

Define Plugin Variable and add it to plugins:

    new webpack.DefinePlugin({
        'NODE_ENV': JSON.stringify(env.NODE_ENV || 'development')
    }),

Now when running webpack command, pass env.NODE_ENV as argument:

webpack --env.NODE_ENV=development

// OR

webpack --env.NODE_ENV development

Now you can access NODE_ENV variable anywhere in your code.

Enumerate the subkeys of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP. Each subkey is a .NET version. It should have Install=1 value if it's present on the machine, an SP value that shows the service pack and an MSI=1 value if it was installed using an MSI. (.NET 2.0 on Windows Vista doesn't have the last one for example, as it is part of the OS.)

Why can't I use a list as a dict key in python?

>>> d = {repr([1,2,3]): 'value'}
{'[1, 2, 3]': 'value'}

(for anybody who stumbles on this question looking for a way around it)

as explained by others here, indeed you cannot. You can however use its string representation instead if you really want to use your list.

lastInsertId() only work after the INSERT query.

Correct:

$stmt = $this->conn->prepare("INSERT INTO users(userName,userEmail,userPass) 
                              VALUES(?,?,?);");
$sonuc = $stmt->execute([$username,$email,$pass]);
$LAST_ID = $this->conn->lastInsertId();

Incorrect:

$stmt = $this->conn->prepare("SELECT * FROM users");
$sonuc = $stmt->execute();
$LAST_ID = $this->conn->lastInsertId(); //always return string(1)=0

result() returns Object type data. . . . result_array() returns Associative Array type data.

SQL Server :

SELECT [activity_dt], count(*)
FROM table1
GROUP BY DATEPART(day, [activity_dt]), DATEPART(hour, [activity_dt]);

Oracle :

SELECT [activity_dt], count(*)
FROM table1
GROUP BY TO_CHAR(activity_dt, 'DD'), TO_CHAR(activity_dt, 'hh');

MySQL :

SELECT [activity_dt], count(*)
FROM table1
GROUP BY hour( activity_dt ) , day( activity_dt )

enum Enum{ Banana, Orange, Apple } ;
static const char * EnumStrings[] = { "bananas & monkeys", "Round and orange", "APPLE" };

const char * getTextForEnum( int enumVal )
{
  return EnumStrings[enumVal];
}

One way I found after some struggling is creating a function which gets data_plot matrix, file name and order as parameter to create boxplots from the given data in the ordered figure (different orders = different figures) and save it under the given file_name.

def plotFigure(data_plot,file_name,order):
    fig = plt.figure(order, figsize=(9, 6))
    ax = fig.add_subplot(111)
    bp = ax.boxplot(data_plot)
    fig.savefig(file_name, bbox_inches='tight')
    plt.close()

In case you want to sort in more than one direction

  public static void sortOutputTable(ref DataTable output)
        {
            DataView dv = output.DefaultView;
            dv.Sort = "specialCode ASC, otherCode DESC";
            DataTable sortedDT = dv.ToTable();
            output = sortedDT;
        }

The other answers to this question seem to hit it spot on. Now how would you figure this out for yourself without stack overflow? Check out IPython, an interactive Python shell that has tab auto-complete.

I think you can try add parameter axis=1 to concat, because output of df.iloc[0,:] and df.iloc[-1,:] are Series and transpose by T:

print df.iloc[0,:]

print df.iloc[-1,:]
a    4
b    d
Name: 3, dtype: object

print pd.concat([df.iloc[0,:], df.iloc[-1,:]], axis=1)
   0  3

You can consider to replace default WordPress jQuery script with Google Library by adding something like the following into theme functions.php file:

function modify_jquery() {
    if (!is_admin()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js', false, '1.10.2');
        wp_enqueue_script('jquery');
    }
}
add_action('init', 'modify_jquery');

The definitions are detailed at the Maven site's page Introduction to the Build Lifecycle, but I have tried to summarize:

Maven defines 4 items of a build process:

1. Lifecycle

   Three built-in lifecycles (aka build lifecycles): default, clean, site. (Lifecycle Reference)

2. Phase

   Each lifecycle is made up of phases, e.g. for the default lifecycle: compile, test, package, install, etc.

3. Plugin

   An artifact that provides one or more goals.

   Based on packaging type (jar, war, etc.) plugins' goals are bound to phases by default. (Built-in Lifecycle Bindings)

4. Goal

   The task (action) that is executed. A plugin can have one or more goals.

   One or more goals need to be specified when configuring a plugin in a POM. Additionally, in case a plugin does not have a default phase defined, the specified goal(s) can be bound to a phase.

Maven can be invoked with:

1. a phase (e.g clean, package)
2. <plugin-prefix>:<goal> (e.g. dependency:copy-dependencies)
3. <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal> (e.g. org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile)

with one or more combinations of any or all, e.g.:

mvn clean dependency:copy-dependencies package

VERSION=$(head -50 pom.xml | awk -F'>' '/SNAPSHOT/ {print $2}' | awk -F'<' '{print $1}')

This is what I used to get the version number, thought there would have been a better maven way to do so

It is the severity level of the error. The levels are from 11 - 20 which throw an error in SQL. The higher the level, the more severe the level and the transaction should be aborted.

You will get the syntax error when you do:

RAISERROR('Cannot Insert where salary > 1000').

Because you have not specified the correct parameters (severity level or state).

If you wish to issue a warning and not an exception, use levels 0 - 10.

From MSDN:

severity

Is the user-defined severity level associated with this message. When using msg_id to raise a user-defined message created using sp_addmessage, the severity specified on RAISERROR overrides the severity specified in sp_addmessage. Severity levels from 0 through 18 can be specified by any user. Severity levels from 19 through 25 can only be specified by members of the sysadmin fixed server role or users with ALTER TRACE permissions. For severity levels from 19 through 25, the WITH LOG option is required.

state

Is an integer from 0 through 255. Negative values or values larger than 255 generate an error. If the same user-defined error is raised at multiple locations, using a unique state number for each location can help find which section of code is raising the errors. For detailed description here

It's not smart enough to realize it's still a "vector" in math terms.

Say rather that it's smart enough to recognize a difference in dimensionality. :-)

I think the simplest thing you can do is select that row positionally using iloc, which gives you a Series with the columns as the new index and the values as the values:

>>> df = pd.DataFrame([list(range(5))], columns=["a{}".format(i) for i in range(5)])
>>> df
   a0  a1  a2  a3  a4
0   0   1   2   3   4
>>> df.iloc[0]
a0    0
a1    1
a2    2
a3    3
a4    4
Name: 0, dtype: int64
>>> type(_)
<class 'pandas.core.series.Series'>

There is also this:

select m from table where not regexp_like(m, '^[0-9]\d+$')

which selects the rows that contains characters from the column you want (which is m in the example but you can change).

Most of the combinations don't work properly in Oracle platforms but this does. Sharing for future reference.

As several people have already said, this is due to autoboxing.

You could create a utility method to check whether the object's class is Integer, Double, etc. But there is no way to know whether an object was created by autoboxing a primitive; once it's boxed, it looks just like an object created explicitly.

So unless you know for sure that your array will never contain a wrapper class without autoboxing, there is no real solution.

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

Add multiple classes:

$("p").addClass("class1 class2 class3");

or in cascade:

$("p").addClass("class1").addClass("class2").addClass("class3");

Very similar also to remove more classes:

$("p").removeClass("class1 class2 class3");

or in cascade:

$("p").removeClass("class1").removeClass("class2").removeClass("class3");
