If you have installed wordpress using apt, the config files are split in multiple directories. In that case you need to run:

sudo chown -R -h www-data:www-data /var/lib/wordpress/wp-content/
sudo chown -R -h www-data:www-data /usr/share/wordpress/wp-content/

The -h switch changes the permissions for symlinks as well, otherwise they are not removable by user www-data

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

        URL url;

        try {
            // get URL content

            String a="http://localhost:8080/TestWeb/index.jsp";
            url = new URL(a);
            URLConnection conn = url.openConnection();

            // open the stream and put it into BufferedReader
            BufferedReader br = new BufferedReader(
                               new InputStreamReader(conn.getInputStream()));

            String inputLine;
            while ((inputLine = br.readLine()) != null) {
                    System.out.println(inputLine);
            }
            br.close();

            System.out.println("Done");

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

I think your code is a bit too complicated and it needs more structure, because otherwise you'll be lost in all equations and operations. In the end this regression boils down to four operations:

1. Calculate the hypothesis h = X * theta
2. Calculate the loss = h - y and maybe the squared cost (loss^2)/2m
3. Calculate the gradient = X' * loss / m
4. Update the parameters theta = theta - alpha * gradient

In your case, I guess you have confused m with n. Here m denotes the number of examples in your training set, not the number of features.

Let's have a look at my variation of your code:

import numpy as np
import random

# m denotes the number of examples here, not the number of features
def gradientDescent(x, y, theta, alpha, m, numIterations):
    xTrans = x.transpose()
    for i in range(0, numIterations):
        hypothesis = np.dot(x, theta)
        loss = hypothesis - y
        # avg cost per example (the 2 in 2*m doesn't really matter here.
        # But to be consistent with the gradient, I include it)
        cost = np.sum(loss ** 2) / (2 * m)
        print("Iteration %d | Cost: %f" % (i, cost))
        # avg gradient per example
        gradient = np.dot(xTrans, loss) / m
        # update
        theta = theta - alpha * gradient
    return theta


def genData(numPoints, bias, variance):
    x = np.zeros(shape=(numPoints, 2))
    y = np.zeros(shape=numPoints)
    # basically a straight line
    for i in range(0, numPoints):
        # bias feature
        x[i][0] = 1
        x[i][1] = i
        # our target variable
        y[i] = (i + bias) + random.uniform(0, 1) * variance
    return x, y

# gen 100 points with a bias of 25 and 10 variance as a bit of noise
x, y = genData(100, 25, 10)
m, n = np.shape(x)
numIterations= 100000
alpha = 0.0005
theta = np.ones(n)
theta = gradientDescent(x, y, theta, alpha, m, numIterations)
print(theta)

At first I create a small random dataset which should look like this:

As you can see I also added the generated regression line and formula that was calculated by excel.

You need to take care about the intuition of the regression using gradient descent. As you do a complete batch pass over your data X, you need to reduce the m-losses of every example to a single weight update. In this case, this is the average of the sum over the gradients, thus the division by m.

The next thing you need to take care about is to track the convergence and adjust the learning rate. For that matter you should always track your cost every iteration, maybe even plot it.

If you run my example, the theta returned will look like this:

Iteration 99997 | Cost: 47883.706462
Iteration 99998 | Cost: 47883.706462
Iteration 99999 | Cost: 47883.706462
[ 29.25567368   1.01108458]

Which is actually quite close to the equation that was calculated by excel (y = x + 30). Note that as we passed the bias into the first column, the first theta value denotes the bias weight.

But you might also want to look into a very different approach, listening for file-system events.

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

A ClassNotFoundException is thrown when the reported class is not found by the ClassLoader. This typically means that the class is missing from the CLASSPATH. It could also mean that the class in question is trying to be loaded from another class which was loaded in a parent classloader and hence the class from the child classloader is not visible. This is sometimes the case when working in more complex environments like an App Server (WebSphere is infamous for such classloader issues).

People often tend to confuse java.lang.NoClassDefFoundError with java.lang.ClassNotFoundException however there's an important distinction. For example an exception (an error really since java.lang.NoClassDefFoundError is a subclass of java.lang.Error) like

java.lang.NoClassDefFoundError:
org/apache/activemq/ActiveMQConnectionFactory

does not mean that the ActiveMQConnectionFactory class is not in the CLASSPATH. Infact its quite the opposite. It means that the class ActiveMQConnectionFactory was found by the ClassLoader however when trying to load the class, it ran into an error reading the class definition. This typically happens when the class in question has static blocks or members which use a Class that's not found by the ClassLoader. So to find the culprit, view the source of the class in question (ActiveMQConnectionFactory in this case) and look for code using static blocks or static members. If you don't have access the the source, then simply decompile it using JAD.

On examining the code, say you find a line of code like below, make sure that the class SomeClass in in your CLASSPATH.

private static SomeClass foo = new SomeClass();

Tip : To find out which jar a class belongs to, you can use the web site jarFinder . This allows you to specify a class name using wildcards and it searches for the class in its database of jars. jarhoo allows you to do the same thing but its no longer free to use.

If you would like to locate the which jar a class belongs to in a local path, you can use a utility like jarscan ( http://www.inetfeedback.com/jarscan/ ). You just specify the class you'd like to locate and the root directory path where you'd like it to start searching for the class in jars and zip files.

Cell padding

is used for formatting purpose which is used to specify the space needed between the edges of the cells and also in the cell contents. The general format of specifying cell padding is as follows:

< table width="100" border="2" cellpadding="5">

The above adds 5 pixels of padding inside each cell .

Cell Spacing:

Cell spacing is one also used f formatting but there is a major difference between cell padding and cell spacing. It is as follows: Cell padding is used to set extra space which is used to separate cell walls from their contents. But in contrast cell spacing is used to set space between cells.

I think we might as well add Apple's App of the year for 2011, Instagram, to the list which uses django intensively.

Y'all suffering yet the solution is simple.

var obj1 = {x: 5, y:5};

var obj2 = {...obj1}; // Boom

a potentially more efficient algorithm than the ones presented here already (especially if there are small prime factons in n). the trick here is to adjust the limit up to which trial division is needed every time prime factors are found:

def factors(n):
    '''
    return prime factors and multiplicity of n
    n = p0^e0 * p1^e1 * ... * pk^ek encoded as
    res = [(p0, e0), (p1, e1), ..., (pk, ek)]
    '''

    res = []

    # get rid of all the factors of 2 using bit shifts
    mult = 0
    while not n & 1:
        mult += 1
        n >>= 1
    if mult != 0:
        res.append((2, mult))

    limit = round(sqrt(n))
    test_prime = 3
    while test_prime <= limit:
        mult = 0
        while n % test_prime == 0:
            mult += 1
            n //= test_prime
        if mult != 0:
            res.append((test_prime, mult))
            if n == 1:              # only useful if ek >= 3 (ek: multiplicity
                break               # of the last prime) 
            limit = round(sqrt(n))  # adjust the limit
        test_prime += 2             # will often not be prime...
    if n != 1:
        res.append((n, 1))
    return res

this is of course still trial division and nothing more fancy. and therefore still very limited in its efficiency (especially for big numbers without small divisors).

this is python3; the division // should be the only thing you need to adapt for python 2 (add from __future__ import division).

The short answer for this is, "because that's what the C++ standard specifies".

Note that you can always specify a constructor that's different from the default, like so:

class Shape  {

  Shape()  {...} //default constructor
  Shape(int h, int w) {....} //some custom constructor


};

class Rectangle : public Shape {
  Rectangle(int h, int w) : Shape(h, w) {...} //you can specify which base class constructor to call

}

The default constructor of the base class is called only if you don't specify which one to call.

If you don't mind changing your HTML, you can use the data-toggle attribute on <button>s. See the Single toggle section of the button examples:

<button type="button" class="btn btn-primary" data-toggle="button">
    Single toggle
</button>

Here's an option using a JQuery extension I made based on the code by waspinator in the comments of the accepted answer:

jQuery.fn.extend({
    printElem: function() {
        var cloned = this.clone();
        var printSection = $('#printSection');
        if (printSection.length == 0) {
            printSection = $('<div id="printSection"></div>')
            $('body').append(printSection);
        }
        printSection.append(cloned);
        var toggleBody = $('body *:visible');
        toggleBody.hide();
        $('#printSection, #printSection *').show();
        window.print();
        printSection.remove();
        toggleBody.show();
    }
});

$(document).ready(function(){
    $(document).on('click', '#btnPrint', function(){
        $('.printMe').printElem();
    });
});

This can be useful if you don't want to have this applied to every single print and just do it on your custom print button (which was my case).

git pull = git fetch + git merge origin/branch

git pull and git pull origin branch only differ in that the latter will only "update" origin/branch and not all origin/* as git pull does.

git pull origin/branch will just not work because it's trying to do a git fetch origin/branch which is invalid.

Question related: git fetch + git merge origin/master vs git pull origin/master

Here are two jQuery patches to help out (maybe already included in jQuery by the time you are reading this):

• Patching jQuery css() Method to Support 'transform'
• jQuery Patch: Animate CSS Rotation and Scale

If you just want to get the information of current directory, you can type:

pwd

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.

i solve by way nuget. the first you install nuget. the second you use.
illustration follow:

third : Check to see if this is the latest version by looking at the "Version" property.

The finaly : you check project have latest version again.

I know this is an old question but here is the solution I found to a very similar coding issue in my own code:

var response = ApiDB.Persons.Include(y => y.JobTitle).Include(b => b.Discipline).Include(b => b.Team).Include(b => b.Site).OrderBy(d => d.DisplayName).ToArray();
        foreach (var person in response)
        {
            person.JobTitle = new JobTitle()
            {
                JobTitle_ID = person.JobTitle.JobTitle_ID,
                JobTitleName = person.JobTitle.JobTitleName,
                PatientInteraction = person.JobTitle.PatientInteraction,
                Active = person.JobTitle.Active,
                IsClinical = person.JobTitle.IsClinical
            };
        }

Since the person object contains everything from the person table and the job title object contains a list of persons with that job title, the database kept self referencing. I thought disabling proxy creation and lazy loading would fix this but unfortunately it didn't.

For the that aren't able to do that, try the solution above. Explicitly creating a new object for each object that self references, but leave out the list of objects or object that goes back to the previous entity will fix it since disabling lazy loading does not appear to work for me.

A public class is one option, if you want something more encapsulated you can use an abstract/anonymous class combination. My favorite part is that autocomplete still works (for PhpStorm) for this but I don't have a public class sitting around.

<?php

final class MyParentClass
{
    /**
     * @return MyStruct[]
     */
    public function getData(): array
    {
        return array(
            $this->createMyObject("One", 1.0, new DateTime("now")),
            $this->createMyObject("Two", 2.0, new DateTime("tommorow"))
        );
    }

    private function createMyObject(string $description, float $magnitude, DateTime $timeStamp): MyStruct
    {
        return new class(func_get_args()) extends MyStruct {
            protected function __construct(array $args)
            {
                $this->description = $args[0];
                $this->magnitude = $args[1];
                $this->timeStamp = $args[2];
            }
        };
    }
}

abstract class MyStruct
{
    public string $description;
    public float $magnitude;
    public DateTime $timeStamp;
}

Write localhost directory path

You might set location directly because it's slightly shorter. If you're trying to be terse, you can usually omit the window. too.

URL assignments to both location.href and location are defined to work in JavaScript 1.0, back in Netscape 2, and have been implemented in every browser since. So take your pick and use whichever you find clearest.

Checkout the -maxdepth flag of find

find . -maxdepth 1 -type d -exec ls -ld "{}" \;

Here I used 1 as max level depth, -type d means find only directories, which then ls -ld lists contents of, in long format.

The Java 7 install on my work PC broke after a patch was forced out to us, giving this error any time you tried to run a Java program. Somehow the entire 'lib' subdirectory of the Java 7 install vanished! Might have been related to having both Java 6 and Java 7 installed -- the 'jre6' directory still had everything there.

In any case, I fixed it by uninstalling both Java 6 and Java 7 and reinstalling just Java 7. But if the file it's complaining about is actually there, then you're likely having a path issue as described in some of the other answers here.

jQuery("[name='test']") 

Although you should avoid it and if possible select by ID (e.g. #myId) as this has better performance because it invokes the native getElementById.

var lat = homeMarker.getPosition().lat();
var lng = homeMarker.getPosition().lng();

See the google.maps.LatLng docs and google.maps.Marker getPosition().

You may try like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {
    g.drawRect (x, y, width, height);    //can use either of the two//
    g.fillRect (x, y, width, height);
    g.setColor(color);
  }

}

where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue

if you want to use rectangle object you could do it like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {    
    Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
    g.setColor(color);
  }
}       

The line onclick = writeLED(1,1) means that you want to immediately execute the function writeLED(arg1, arg2) with arguments 1, 1 and assign the return value; you need to instead create a function that will execute with those arguments and assign that. The topmost answer gave one example - another is to use the bind() function like so:

    var writeLEDWithSpecifiedArguments = writeLED.bind(this, 1,1);
    document.getElementById('buttonLED'+id).onclick = writeLEDWithSpecifiedArguments;

In Laravel (PHP) we can do it in the following clear and elegant way (using file modification timestamp):

<script src="{{ asset('/js/your.js?v='.filemtime('js/your.js')) }}"></script>

And similar for CSS

<link rel="stylesheet" href="{{asset('css/your.css?v='.filemtime('css/your.css'))}}">

Example HTML output (filemtime return time as as a Unix timestamp)

<link rel="stylesheet" href="assets/css/your.css?v=1577772366">

You don't need to. Just slap it on there as many times as you want and as often as you want. MDN explains identical event listeners:

If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and they do not need to be removed manually with the removeEventListener method.

Interestingly enough I tried both of these in LinqPad and the variant using group from Dmitry Gribkov by appears to be quicker. (also the final distinct is not required as the result is already distinct.

My (somewhat simple) code was:

public class Pair 
{ 
    public int id {get;set;}
    public string Arb {get;set;}
}

void Main()
{

    var theList = new List<Pair>();
    var randomiser = new Random();
    for (int count = 1; count < 10000; count++)
    {
        theList.Add(new Pair 
        {
            id = randomiser.Next(1, 50),
            Arb = "not used"
        });
    }

    var timer = new Stopwatch();
    timer.Start();
    var distinct = theList.GroupBy(c => c.id).Select(p => p.First().id);
    timer.Stop();
    Debug.WriteLine(timer.Elapsed);

    timer.Start();
    var otherDistinct = theList.Select(p => p.id).Distinct();
    timer.Stop();
    Debug.WriteLine(timer.Elapsed);
}

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

Here's an example:

public class Main {

    public static void main(String[] args) {

        double val1 = 100;
        double val2 = 10;
        char operation = 'd';
        double result = 0;

        switch (operation) {

            case 'a':
                result = val1 + val2; break;

            case 's':
                result = val1 - val2; break;
            case 'd':
                if (val2 != 0)
                    result = val1 / val2; break;
            case 'm':
                result = val1 * val2; break;

            default: System.out.println("Not a defined operation");


        }

        System.out.println(result);
    }
}

Android hasn't provided a native method. Nor the AppCompat.

Try this library: https://github.com/rengwuxian/MaterialEditText

This might be what you want.

// mutiple image retrieve

 File folPath = new File(getIntent().getStringExtra("folder_path"));
 File[] imagep = folPath.listFiles();

 for (int i = 0; i < imagep.length ; i++) {
     imageModelList.add(new ImageModel(imagep[i].getAbsolutePath(), Uri.parse(imagep[i].getAbsolutePath())));
 }
 imagesAdapter.notifyDataSetChanged();

You Should Used Collection keyword in Controller. Like Here..

public function ApiView(){
    return User::collection(Profile::all());
}

Here, User is Resource Name and Profile is Model Name. Thank You.

Current date is in yyyy-mm-dd format. You can convert it into yyyymmdd format using substring function:

select substr(current date,1,4)||substr(current date,6,2)||substr(currentdate,9,2)

@media print{
    *{display:none;}
    #mydiv{display:block;}
}

The Thread class is used for creating and manipulating a thread in Windows.

A Task represents some asynchronous operation and is part of the Task Parallel Library, a set of APIs for running tasks asynchronously and in parallel.

In the days of old (i.e. before TPL) it used to be that using the Thread class was one of the standard ways to run code in the background or in parallel (a better alternative was often to use a ThreadPool), however this was cumbersome and had several disadvantages, not least of which was the performance overhead of creating a whole new thread to perform a task in the background.

Nowadays using tasks and the TPL is a far better solution 90% of the time as it provides abstractions which allows far more efficient use of system resources. I imagine there are a few scenarios where you want explicit control over the thread on which you are running your code, however generally speaking if you want to run something asynchronously your first port of call should be the TPL.

You can also press = while less is open to just display (at the bottom of the screen) information about the current screen, including line numbers, with format:

myfile.txt lines 20530-20585/1816468 byte 1098945/116097872 1%  (press RETURN)

So here for example, the screen was currently showing lines 20530-20585, and the files has a total of 1816468 lines.

Use fs.writeFileSync inside the try/catch block as below.

`var fs = require('fs');

     return results;
 } catch (error) {

Using map:

var values = $("input[id='task']")
              .map(function(){return $(this).val();}).get();

If you change or remove the id (which should be unique), you may also use the selector $("input[name='task\\[\\]']")

This blog post was helpful for me. I used the "Homebrew built Vim" solution, which in my case saved the new version in /usr/local/bin. At this point, the post suggested hiding the system vim, which didn't work for me, so I used an alias instead.

$ brew install vim
$ alias vim='/path/to/new/vim
$ which vim
vim: aliased to /path/to/new/vim

team! For execute SQL-query from your Servlet you should add JDBC jar library in folder

WEB-INF/lib

After this you could call driver, example :

Class.forName("oracle.jdbc.OracleDriver");

Now Y can use connection to DB-server

==> 73!

It means "a python object", i.e. not one of the builtin scalar types supported by numpy.

np.array([object()]).dtype
=> dtype('O')

So many answers, and no one ever made a benchmark to compare sync vs async vs require. I described the difference in use cases of reading json in memory via require, readFileSync and readFile here.

DECLARE @MinDate DATETIME = '2012-09-23 00:02:00.000',
    @MaxDate DATETIME = '2012-09-25 00:00:00.000';

SELECT  TOP (DATEDIFF(DAY, @MinDate, @MaxDate) + 1) Dates = DATEADD(DAY, ROW_NUMBER() OVER(ORDER BY a.object_id) - 1, @MinDate)
FROM sys.all_objects a CROSS JOIN sys.all_objects b;

This could also happens if you put a @PreAuthorize or @PostAuthorize in a Bean in creation. I would recommend to move such annotations to methods of interest.

In recent Git (I'm using v2.15.1), the following will merge upstream submodule changes into the submodules recursively:

git submodule update --recursive --remote --merge

You may add --init to initialize any uninitialized submodules and use --rebase if you want to rebase instead of merge.

You need to commit the changes afterwards:

git add . && git commit -m 'Update submodules to latest revisions'

not equals. See here for a list of conditions

Why you need to implement shuffle when it already exists? Stay on the shoulders of giants.

import random

d1 = {0:'zero', 1:'one', 2:'two', 3:'three', 4:'four',
     5:'five', 6:'six', 7:'seven', 8:'eight', 9:'nine'}

keys = list(d1)
random.shuffle(keys)

d2 = {}
for key in keys: d2[key] = d1[key]

print(d1)
print(d2)

When programming I often have strings with just plain A-Za-z and 0-9. No need for difficult Index actions. This extension is based on the plain old left / mid / right functions.

extension String {

    // LEFT
    // Returns the specified number of chars from the left of the string
    // let str = "Hello"
    // print(str.left(3))         // Hel
    func left(_ to: Int) -> String {
        return "\(self[..<self.index(startIndex, offsetBy: to)])"
    }

    // RIGHT
    // Returns the specified number of chars from the right of the string
    // let str = "Hello"
    // print(str.left(3))         // llo
    func right(_ from: Int) -> String {
        return "\(self[self.index(startIndex, offsetBy: self.length-from)...])"
    }

    // MID
    // Returns the specified number of chars from the startpoint of the string
    // let str = "Hello"
    // print(str.left(2,amount: 2))         // ll
    func mid(_ from: Int, amount: Int) -> String {
        let x = "\(self[self.index(startIndex, offsetBy: from)...])"
        return x.left(amount)
    }
}

Have you tried:

SELECT Cast( 2.555 as decimal(53,8))

This would return 2.55500000. Is that what you want?

UPDATE:

Apparently you can also use SQL_VARIANT_PROPERTY to find the precision and scale of a value. Example:

SELECT SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Precision'),
SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Scale')

returns 8|7

You may be able to use this in your conversion process...

JSON.stringify(data).length return string length not Object length, you can use Object.keys.

<% for(var i=0; i < Object.keys(data).length ; i++) {%>

https://stackoverflow.com/a/14379528/3224296

>>> list1 = [[], [], [], [], [], 'text', 'text2', [], 'moreText']
>>> list2 = [e for e in list1 if e]
>>> list2
['text', 'text2', 'moreText']

Let us consider a Man(User or an Object) wants some work to be done. He will contact a middle man(Interface) who will be having a contract with the companies(real world objects created using implemented classes). Few types of works will be defined by him which companies will implement and give him results. Each and every company will implement the work in its own way but the result will be same. Like this User will get its work done using an single interface. I think Interface will act as visible part of the systems with few commands which will be defined internally by the implementing inner sub systems.

With Log4j2, this can be achieved using the following utility method added to your code.

private static void setLogLevel() {
  if (Boolean.getBoolean("log4j.debug")) {
    Configurator.setLevel(System.getProperty("log4j.logger"), Level.DEBUG);
  }
}

You need these imports

import org.apache.logging.log4j.Level;
import org.apache.logging.log4j.core.config.Configurator;

Now invoke the setLogLevel method in your main() or whereever appropriate and pass command line params -Dlog4j.logger=com.mypackage.Thingie and -Dlog4j.debug=true.

String are immutable in Java. You can't change them.

You need to create a new string with the character replaced.

String myName = "domanokz";
String newName = myName.substring(0,4)+'x'+myName.substring(5);

Or you can use a StringBuilder:

StringBuilder myName = new StringBuilder("domanokz");
myName.setCharAt(4, 'x');

System.out.println(myName);

I think you're looking for this:

elements = [10, 11, 12, 13, 14, 15]
indices = (1,1,2,1,5)

result_list = [elements[i] for i in indices]    

I'm using json lib from http://json-lib.sourceforge.net/

    m.put("email_content","test email content");

    //generate JSON Object
    JSONObject json = JSONObject.fromObject(content);
    String message = json.toString();
    ...
}

public void receive(String jsonMessage)
{
    //parse attributes
    JSONObject json = JSONObject.fromObject(jsonMessage);
    String to = (String) json.get("send_to");

I think, the statement

everyone hates it except me

makes any further discussion waste: when you keep using Git, they will blame you if anything goes wrong.

Apart from this, for me Git has two advantages over a centralized VCS that I appreciate most (as partly described by Rob Sobers):

• automatic backup of the whole repo: everytime someone pulls from the central repo, he/she gets a full history of the changes. When one repo gets lost: don't worry, take one of those present on every workstation.
• offline repo access: when I'm working at home (or in an airplane or train), I can see the full history of the project, every single checkin, without starting up my VPN connection to work and can work like I were at work: checkin, checkout, branch, anything.

But as I said: I think that you're fighting a lost battle: when everyone hates Git, don't use Git. It could help you more to know why they hate Git instead of trying them to convince them.

If they simply don't want it 'cause it's new to them and are not willing to learn something new: are you sure that you will do successful development with that staff?

Does really every single person hate Git or are they influenced by some opinion leaders? Find the leaders and ask them what's the problem. Convince them and you'll convince the rest of the team.

If you cannot convince the leaders: forget about using Git, take the TFS. Will make your life easier.

I experienced this issue after installing Cocoapods. Now happens everytime I update some pods. Solution I've found:

Go to terminal:

1) pod deintegrate
2) pod install

Also, check the item "Always Embed Swift Libraries" in your Build Settings. It should be "faded" indicating it is using the default configuration. If its set to a manual YES, hit delete over it to revert it to the default configuration. This stopped the behavior.

Let me quote this:

Hibernate created a new language named Hibernate Query Language (HQL), the syntax is quite similar to database SQL language. The main difference between is HQL uses class name instead of table name, and property names instead of column name.

As far as I can see you are using the table name.

So it should be like this:

Query query = session.createQuery("from Employee");

You could try something like this in javascript:
var regex = /[^a-zA-Z]/g;

and have a keyup event.
$("#nameofInputbox").value.replace(regex, "");

I am not sure, but might be what you want:

var c = 0;
function setBgPosition()
{
    var numbers = [0, -120, -240, -360, -480, -600, -720];
    function run()
    {
        Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
        if (c<=numbers.length)
        {
            setTimeout(run, 200);
        }
        else
        {
            Ext.get('common-spinner').setStyle('background-position', numbers[0] + 'px 0px');
        }
    }
    setTimeout(run, 200);
}
setBgPosition();

You can try this:

Calendar sDate = Calendar.getInstance();
Calendar eDate = Calendar.getInstance();
sDate.setTime(startDate.getTime());
eDate.setTime(endDate.getTime());
int difInMonths = sDate.get(Calendar.MONTH) - eDate.get(Calendar.MONTH);

I think this should work. I used something similar for my project and it worked for what I needed (year diff). You get a Calendar from a Date and just get the month's diff.

Besides the way suggested in the "possible duplicate", the other main way of getting around this problem is for the array itself (or at least a template of one) to be supplied by the caller, who will hopefully know the concrete type and can thus safely create the array.

This is the way methods like ArrayList.toArray(T[]) are implemented. I'd suggest you take a look at that method for inspiration. Better yet, you should probably be using that method anyway as others have noted.

You're using the exec form of ENTRYPOINT. Unlike the shell form, the exec form does not invoke a command shell. This means that normal shell processing does not happen. For example, ENTRYPOINT [ "echo", "$HOME" ] will not do variable substitution on $HOME. If you want shell processing then either use the shell form or execute a shell directly, for example: ENTRYPOINT [ "sh", "-c", "echo $HOME" ].
When using the exec form and executing a shell directly, as in the case for the shell form, it is the shell that is doing the environment variable expansion, not docker.(from Dockerfile reference)

In your case, I would use shell form

ENTRYPOINT ./greeting --message "Hello, $ADDRESSEE\!"

egyamado's answer was really helpful! You can enhance it for your particular setup with something like this:

import sublime, sublime_plugin
import webbrowser

class OpenBrowserCommand(sublime_plugin.TextCommand):
   def run(self, edit, keyPressed, localHost, pathToFiles):  
      for region in self.view.sel():  
         if not region.empty():  
            # Get the selected text  
            url = self.view.substr(region)  
            # prepend beginning of local host url 
            url = localHost + url  
         else:
            # prepend beginning of local host url 
            url = localHost + self.view.file_name()
            # replace local path to file
            url = url.replace(pathToFiles, "")


         if keyPressed == "1":
            navigator = webbrowser.get("open -a /Applications/Firefox.app %s")
         if keyPressed == "2":
            navigator = webbrowser.get("open -a /Applications/Google\ Chrome.app %s")
         if keyPressed == "3":
            navigator = webbrowser.get("open -a /Applications/Safari.app %s")
         navigator.open_new(url)

And then in your keybindings:

{ "keys": ["alt+1"], "command": "open_browser", "args": {"keyPressed": "1", "localHost": "http://nbrown.smartdestinations.com", "pathToFiles":"/opt/local/apache2/htdocs"}},
{ "keys": ["alt+2"], "command": "open_browser", "args": {"keyPressed": "2", "localHost": "http://nbrown.smartdestinations.com", "pathToFiles":"/opt/local/apache2/htdocs"}},
{ "keys": ["alt+3"], "command": "open_browser", "args": {"keyPressed": "3", "localHost": "http://nbrown.smartdestinations.com", "pathToFiles":"/opt/local/apache2/htdocs"}}

We store sample urls at the top of all our templates, so the first part allows you to highlight that sample URL and launch it in a browser. If no text is highlighted, it will simply use the file name. You can adjust the command calls in the keybindings to your localhost url and the system path to the documents you're working on.

I had the same issue. Not able to install neither using Marketplace nor Servers tab.

Following is the alternative.

1) Help -> Install New Software

2) Use url : http://download.oracle.com/otn_software/oepe/12.1.3.6/luna/repository Above is the OEPE tool provided by oracle for EE development.

3) From all the suggestions, select glassfish tools.

4) Install it.

5) Restart eclipse.

Eclipse 4.4.2 Luna JDK : 1.8

ResourceBundle doesn't load files? You need to get the files into a resource first. How about just loading into a FileInputStream then a PropertyResourceBundle

   FileInputStream fis = new FileInputStream("skyscrapper.properties");
   resourceBundle = new PropertyResourceBundle(fis);

Or if you need the locale specific code, something like this should work

File file = new File("skyscrapper.properties");
URL[] urls = {file.toURI().toURL()};
ClassLoader loader = new URLClassLoader(urls);
ResourceBundle rb = ResourceBundle.getBundle("skyscrapper", Locale.getDefault(), loader);

                            <tr>
                                <td>data</td><td>data</td>
                            </tr>
                    </table>
                </div>
            </td>
        </tr>
    </tbody>
</table>

This is much like a previous example above. I found when trying to implement that example that if the table row to be expanded was clicked while it was not expanded it would disappear, and it would no longer be expandable

To fix that I simply removed the ability to click the expandable element for slide up and made it so that you can only toggle using the above table row.

I also made some minor changes to HTML and corresponding jQuery.

NOTE: I would have just made a comment but am not allowed to yet therefore the long post. Just wanted to post this as it took me a bit to figure out what was happening to the disappearing table row.

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

You can use a modulo operation for that.

if (n ** (1.0/3)) % 1 != 0:
    print("We have a decimal number here!")

My problem was due to a LOW MTU over a VPN connection.

netsh interface ipv4 show inter

Idx  Met   MTU   State        Name
---  ---  -----  -----------  -------------------
  1 4275 4294967295  connected    Loopback Pseudo-Interface 1
 10 4250   **1300**  connected    Wireless Network Connection
 31   25   1400  connected    Remote Access to XYZ Network

Fix: netsh interface ipv4 set interface "Wireless Network Connection" mtu=1400

It may be an issue over a non-VPN connection also...

Even if fileno(FILE *) may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.

To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)

x.each_with_index { |v, i| puts "current index...#{i}" }

To fetch a remote PR into your local repo,

git fetch origin pull/$ID/head:$BRANCHNAME

where $ID is the pull request id and $BRANCHNAME is the name of the new branch that you want to create. Once you have created the branch, then simply

git checkout $BRANCHNAME

See the official GitHub documentation for more.

I got the same problem and my solution was to remove webconfig file from the directory.. then it works..

You left off the / (pattern delimiter) and $ (match end string).

preg_match("/^[a-zA-Z0-9]+$/", $value)

All you need to do is

$ git branch -rd origin/whatever 

It's that simple. There is no reason to call a gc here.

I got around the issue by using a convert on the "?", so my code looks like convert(char(50),?) and that got rid of the truncation error.

How about adding a new script tag to <head> with the script to (re)load? Something like below:

<script>
   function load_js()
   {
      var head= document.getElementsByTagName('head')[0];
      var script= document.createElement('script');
      script.src= 'source_file.js';
      head.appendChild(script);
   }
   load_js();
</script>

The main point is inserting a new script tag -- you can remove the old one without consequence. You may need to add a timestamp to the query string if you have caching issues.

I simply use this when ever I need to work out a percentage..

ROUND(CAST((Numerator * 100.0 / Denominator) AS FLOAT), 2) AS Percentage

Note that 100.0 returns decimals, whereas 100 on it's own will round up the result to the nearest whole number, even with the ROUND() function!

If you are using firefox then the firebug plug-in console is an excellent way of examining objects

console.debug(myObject);

Alternatively you can loop through the properties (including methods) like this:

for (property in object) {
    // do what you want with property, object[property].value
}

For those who don't have time to refactor the code to replace arrays with Collections (for example ArrayList), there is an alternative. Unlike Collections, the length of an array cannot be changed, but the array can be replaced, like this:

array = push(array, item);

The drawbacks are that

• the whole array has to be copied each time you push, and
• the original array Object is not changed, so you have to update the variable(s) as appropriate.

Here is the push method for String:
(You can create multiple push methods, one for String, one for int, etc)

private static String[] push(String[] array, String push) {
    String[] longer = new String[array.length + 1];
    for (int i = 0; i < array.length; i++)
        longer[i] = array[i];
    longer[array.length] = push;
    return longer;
}

This alternative is more efficient, shorter & harder to read:

private static String[] push(String[] array, String push) {
    String[] longer = new String[array.length + 1];
    System.arraycopy(array, 0, longer, 0, array.length);
    longer[array.length] = push;
    return longer;
}

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

In this case,

sb.setLength(sb.length() - 1);

is preferable as it just assign the last value to '\0' whereas deleting last character does System.arraycopy

If you use Material Components:

CustomDialog.kt

class CustomDialog: DialogFragment() {

    override fun getTheme() = R.style.RoundedCornersDialog

}

styles.xml

<style name="RoundedCornersDialog" parent="Theme.MaterialComponents.Dialog">
    <item name="dialogCornerRadius">dimen</item>
</style>

Direct get a count of row

Using Eloquent

 //Useing Eloquent
 $count = Model::count();    

 //example            
 $count1 = Wordlist::count();

Using query builder

 //Using query builder
 $count = \DB::table('table_name')->count();

 //example
 $count2 = \DB::table('wordlist')->where('id', '<=', $correctedComparisons)->count();

Linux, Qt Creator >= 3.4:

You could edit theese themes:

/usr/share/qtcreator/themes/default.creatortheme
/usr/share/qtcreator/themes/dark.creatortheme

string str = "GoodMorning"

string strModified = str.Substring(0,5);

If that's a valid date/time entry then excel simply stores it as a number (days are integers and the time is the decimal part) so you can do a simple subtraction.

I'm not sure if 7/6 is 7th June or 6th July, assuming the latter then it's a future date so you can get the difference in days with

=INT(A1-TODAY())

Make sure you format result cell as general or number (not date)

Have you tried mysql_ping()?

Update: From PHP 5.5 onwards, use mysqli_ping() instead.

Pings a server connection, or tries to reconnect if the connection has gone down.

if ($mysqli->ping()) {
  printf ("Our connection is ok!\n"); 
} else {
  printf ("Error: %s\n", $mysqli->error); 
}

Alternatively, a second (less reliable) approach would be:

$link = mysql_connect('localhost','username','password');
//(...)
if($link == false){
    //try to reconnect
}

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.

Regular expressions actually aren't part of ANSI C. It sounds like you might be talking about the POSIX regular expression library, which comes with most (all?) *nixes. Here's an example of using POSIX regexes in C (based on this):

#include <regex.h>        
regex_t regex;
int reti;
char msgbuf[100];

/* Compile regular expression */
reti = regcomp(&regex, "^a[[:alnum:]]", 0);
if (reti) {
    fprintf(stderr, "Could not compile regex\n");
    exit(1);
}

/* Execute regular expression */
reti = regexec(&regex, "abc", 0, NULL, 0);
if (!reti) {
    puts("Match");
}
else if (reti == REG_NOMATCH) {
    puts("No match");
}
else {
    regerror(reti, &regex, msgbuf, sizeof(msgbuf));
    fprintf(stderr, "Regex match failed: %s\n", msgbuf);
    exit(1);
}

/* Free memory allocated to the pattern buffer by regcomp() */
regfree(&regex);

Alternatively, you may want to check out PCRE, a library for Perl-compatible regular expressions in C. The Perl syntax is pretty much that same syntax used in Java, Python, and a number of other languages. The POSIX syntax is the syntax used by grep, sed, vi, etc.

SSL23_GET_SERVER_HELLO:unknown protocol

This error happens when OpenSSL receives something other than a ServerHello in a protocol version it understands from the server. It can happen if the server answers with a plain (unencrypted) HTTP. It can also happen if the server only supports e.g. TLS 1.2 and the client does not understand that protocol version. Normally, servers are backwards compatible to at least SSL 3.0 / TLS 1.0, but maybe this specific server isn't (by implementation or configuration).

It is unclear whether you attempted to pass --no-check-certificate or not. I would be rather surprised if that would work.

A simple test is to use wget (or a browser) to request http://example.com:443 (note the http://, not https://); if it works, SSL is not enabled on port 443. To further debug this, use openssl s_client with the -debug option, which right before the error message dumps the first few bytes of the server response which OpenSSL was unable to parse. This may help to identify the problem, especially if the server does not answer with a ServerHello message. To see what exactly OpenSSL is expecting, check the source: look for SSL_R_UNKNOWN_PROTOCOL in ssl/s23_clnt.c.

In any case, looking at the apache error log may provide some insight too.

I've tried various methods like LAB color space, HSV comparisons and I've found that luminosity works pretty well for this purpose.

Here is Python version

def lum(c):
    def factor(component):
        component = component / 255;
        if (component <= 0.03928):
            component = component / 12.92;
        else:
            component = math.pow(((component + 0.055) / 1.055), 2.4);

        return component
    components = [factor(ci) for ci in c]

    return (components[0] * 0.2126 + components[1] * 0.7152 + components[2] * 0.0722) + 0.05;

def color_distance(c1, c2):

    l1 = lum(c1)
    l2 = lum(c2)
    higher = max(l1, l2)
    lower = min(l1, l2)

    return (higher - lower) / higher


c1 = ImageColor.getrgb('white')
c2 = ImageColor.getrgb('yellow')
print(color_distance(c1, c2))

Will give you

0.0687619047619048

This worked for me on Debian stretch

sudo apt-get update
sudo apt install php-mbstring
service apache2 restart

Here is the code of removing duplicates values from NSMutable Array..it will work for you. myArray is your Mutable Array that you want to remove duplicates values..

for(int j = 0; j < [myMutableArray count]; j++){
    for( k = j+1;k < [myMutableArray count];k++){
    NSString *str1 = [myMutableArray objectAtIndex:j];
    NSString *str2 = [myMutableArray objectAtIndex:k];
    if([str1 isEqualToString:str2])
        [myMutableArray removeObjectAtIndex:k];
    }
 } // Now print your array and will see there is no repeated value

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } });

The feature you're looking for is filter. It is capable of doing a range of image effects, including brightness:

#myimage {
    filter: brightness(50%);
}

You can find a helpful article about it here: http://www.html5rocks.com/en/tutorials/filters/understanding-css/

An another: http://davidwalsh.name/css-filters

And most importantly, the W3C specs: https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/index.html

Note this is something that's only very recently coming into CSS as a feature. It is available, but a large number of browsers out there won't support it yet, and those that do support it will require a vendor prefix (ie -webkit-filter:, -moz-filter, etc).

It is also possible to do filter effects like this using SVG. SVG support for these effects is well established and widely supported (the CSS filter specs have been taken from the existing SVG specs)

Also note that this is not to be confused with the proprietary filter style available in old versions of IE (although I can predict a problem with the namespace clash when the new style drops its vendor prefix).

If none of that works for you, you could still use the existing opacity feature, but not the way you're thinking: simply create a new element with a solid dark colour, place it on top of your image, and fade it out using opacity. The effect will be of the image behind being darkened.

Finally you can check the browser support of filter here.

Forget about cluttered namespaces... And consider the poor soul who has to read and understand your code on GitHub, in vi, Notepad++, or some other non-IDE text editor.

That person has to painstakingly look up every token that comes from one of the wildcards against all the classes and references in each wildcarded scope... just to figure out what in the heck is going on.

If you're writing code for the compiler only - and you know what you're doing - I'm sure there's no problem with wildcards.

But if other people - including future you - want to quickly make sense of a particular code file on one reading, then explicit references help a lot.

At https://github.com/BITPlan/com.bitplan.antlr you'll find an ANTLR java library with some useful helper classes and a few complete examples. It's ready to be used with maven and if you like eclipse and maven.

https://github.com/BITPlan/com.bitplan.antlr/blob/master/src/main/antlr4/com/bitplan/exp/Exp.g4

is a simple Expression language that can do multiply and add operations. https://github.com/BITPlan/com.bitplan.antlr/blob/master/src/test/java/com/bitplan/antlr/TestExpParser.java has the corresponding unit tests for it.

https://github.com/BITPlan/com.bitplan.antlr/blob/master/src/main/antlr4/com/bitplan/iri/IRIParser.g4 is an IRI parser that has been split into the three parts:

1. parser grammar
2. lexer grammar
3. imported LexBasic grammar

https://github.com/BITPlan/com.bitplan.antlr/blob/master/src/test/java/com/bitplan/antlr/TestIRIParser.java has the unit tests for it.

Personally I found this the most tricky part to get right. See http://wiki.bitplan.com/index.php/ANTLR_maven_plugin

https://github.com/BITPlan/com.bitplan.antlr/tree/master/src/main/antlr4/com/bitplan/expr

contains three more examples that have been created for a performance issue of ANTLR4 in an earlier version. In the meantime this issues has been fixed as the testcase https://github.com/BITPlan/com.bitplan.antlr/blob/master/src/test/java/com/bitplan/antlr/TestIssue994.java shows.

This will get you to an answer for your simple case, but can you expand on how you'll know which columns will need to be compared (B and C in this case) and what the initial range (A1:D5 in this case) will be? Then I can try to provide a more complete answer.

Sub setCondFormat()
    Range("B3").Select
    With Range("B3:H63")
        .FormatConditions.Add Type:=xlExpression, Formula1:= _
          "=IF($D3="""",FALSE,IF($F3>=$E3,TRUE,FALSE))"
        With .FormatConditions(.FormatConditions.Count)
            .SetFirstPriority
            With .Interior
                .PatternColorIndex = xlAutomatic
                .Color = 5287936
                .TintAndShade = 0
            End With
        End With
    End With
End Sub

Note: this is tested in Excel 2010.

Edit: Updated code based on comments.

I came here looking for the answer and since no one put the command for the oracle Java 11 but only openjava 11 I figured out how to do it on Ubuntu, the syntax is as following:

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java11-installer

If you have Homebrew installed, you can do this.

# check the zsh info
brew info zsh

# install zsh
brew install --without-etcdir zsh

# add shell path
sudo vim /etc/shells

# add the following line into the very end of the file(/etc/shells)
/usr/local/bin/zsh

# change default shell
chsh -s /usr/local/bin/zsh

Hope it helps, thanks.

I had this problem to install laravel/lumen.

It can be resolved with the following command:

$ sudo chown -R $USER ~/.composer/

While writing this question, I discovered the answer. Installing a CA from Safari no longer automatically trusts it. I had to manually trust it from the Certificate Trust Settings panel (also mentioned in this question).

I debated canceling the question, but I thought it might be helpful to have some of the relevant code and log details someone might be looking for. Also, I never encountered the issue until iOS 11. I even went back and reconfirmed that it automatically works up through iOS 10.

I've never needed to touch that settings panel before, because any installed certificates were automatically trusted. Maybe it will change by the time iOS 11 ships, but I doubt it. Hopefully this helps save someone the time I wasted.

If anyone knows why this behaves differently for some people on different versions of iOS, I'd love to know in comments.

Update 1: Checking out the first iOS 12 beta, it looks like things remain the same. This question/answer/comments are still relevant on iOS 12.

Update 2: Same solution seems to be needed on iOS 13 beta builds as well.

The SaveFileDialog control won't do any saving at all. All it does is providing you a convenient interface to actually display Windows' default file save dialog.

1. Set the property InitialDirectory to the drive you'd like it to show some other default. Just think of other computers that might have a different layout. By default windows will save the directory used the last time and present it again.

2. That is handled outside the control. You'll have to check the dialog's results and then do the saving yourself (e.g. write a text or binary file).

Just as a quick example (there are alternative ways to do it). savefile is a control of type SaveFileDialog

SaveFileDialog savefile = new SaveFileDialog(); 
// set a default file name
savefile.FileName = "unknown.txt";
// set filters - this can be done in properties as well
savefile.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";

if (savefile.ShowDialog() == DialogResult.OK)
{
    using (StreamWriter sw = new StreamWriter(savefile.FileName))
        sw.WriteLine ("Hello World!");
}

I had the same problem while designing a template in Mailjet. Solution of the problem was minified CSS code inside <style> tags.

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

test output:

1,3,
1,4,
1,5,
2,3,

Easiest way to solve this problem is install ASP.NET MVC 3 from Web Platforms installer.

http://www.microsoft.com/web/downloads/

Or by using Nuget command

Install-Package Microsoft.AspNet.Mvc -Version 3.0.50813.1

Two approaches leap to mind.

First, don't use scanf. Use fgets() which takes a parameter to specify the buffer size, and which leaves any newline characters intact. A simple loop over the file that prints the buffer content should naturally copy the file intact.

Second, use fread() or the common C idiom with fgetc(). These would process the file in fixed-size chunks or a single character at a time.

If you must process the file over white-space delimited strings, then use either fgets or fread to read the file, and something like strtok to split the buffer at whitespace. Don't forget to handle the transition from one buffer to the next, since your target strings are likely to span the buffer boundary.

If there is an external requirement to use scanf to do the reading, then limit the length of the string it might read with a precision field in the format specifier. In your case with a 999 byte buffer, then say scanf("%998s", str); which will write at most 998 characters to the buffer leaving room for the nul terminator. If single strings longer than your buffer are allowed, then you would have to process them in two pieces. If not, you have an opportunity to tell the user about an error politely without creating a buffer overflow security hole.

Regardless, always validate the return values and think about how to handle bad, malicious, or just malformed input.

Try preventing default on mousedown event:

or

Find one element

To find the element with a given name in an array you can use find:

arr.find(item=>item.name=="k1");

Note that find will return just one item (namely the first match):

{
  "name": "k1",
  "value": "abc"
}

Find all elements

In your original array there's only one item occurrence of each name.

If the array contains multiple elements with the same name and you want them all then use filter, which will return an array.

var arr = [];_x000D_
arr.push({name:"k1", value:"abc"});_x000D_
arr.push({name:"k2", value:"hi"});_x000D_
arr.push({name:"k3", value:"oa"});_x000D_
arr.push({name:"k1", value:"def"});_x000D_
_x000D_
var item;_x000D_
_x000D_
// find the first occurrence of item with name "k1"_x000D_
item = arr.find(item=>item.name=="k1");_x000D_
console.log(item);_x000D_
_x000D_
// find all occurrences of item with name "k1"_x000D_
// now item is an array_x000D_
item = arr.filter(item=>item.name=="k1");_x000D_
console.log(item);

Find indices

Similarly, for indices you can use findIndex (for finding the first match) and filter + map to find all indices.

var arr = [];_x000D_
arr.push({name:"k1", value:"abc"});_x000D_
arr.push({name:"k2", value:"hi"});_x000D_
arr.push({name:"k3", value:"oa"});_x000D_
arr.push({name:"k1", value:"def"});_x000D_
_x000D_
var idx;_x000D_
_x000D_
// find index of the first occurrence of item with name "k1"_x000D_
idx = arr.findIndex(item=>item.name == "k1");_x000D_
console.log(idx, arr[idx].value);_x000D_
_x000D_
// find indices of all occurrences of item with name "k1"_x000D_
// now idx is an array_x000D_
idx = arr.map((item, i) => item.name == "k1" ? i : '').filter(String);_x000D_
console.log(idx);

You must create a new XMLHttpRequest instance and load the contents of the json file.

This tip work for me (https://codepen.io/KryptoniteDove/post/load-json-file-locally-using-pure-javascript):

 function loadJSON(callback) {   

    var xobj = new XMLHttpRequest();
        xobj.overrideMimeType("application/json");
    xobj.open('GET', 'my_data.json', true); // Replace 'my_data' with the path to your file
    xobj.onreadystatechange = function () {
          if (xobj.readyState == 4 && xobj.status == "200") {
            // Required use of an anonymous callback as .open will NOT return a value but simply returns undefined in asynchronous mode
            callback(xobj.responseText);
          }
    };
    xobj.send(null);  
 }

 loadJSON(function(response) {
    // Parse JSON string into object
    var actual_JSON = JSON.parse(response);
 });

Also, while installing Visual Studio 2013, ensure that you have checked "Web Developer Tools"

Dim f as Range

Set f=ActiveSheet.Cells.Find(...)

If Not f Is Nothing then
    msgbox "Row=" & f.Row & vbcrlf & "Column=" & f.Column
Else
    msgbox "value not found!"
End If

Is there a way to limit a regex to 100 characters WITH regex?

Your example suggests that you'd like to grab a number from inside the regex and then use this number to place a maximum length on another part that is matched later in the regex. This usually isn't possible in a single pass. Your best bet is to have two separate regular expressions:

• one to match the maximum length you'd like to use
• one which uses the previously extracted value to verify that its own match does not exceed the specified length

If you just want to limit the number of characters matched by an expression, most regular expressions support bounds by using braces. For instance,

\d{3}-\d{3}-\d{4}

will match (US) phone numbers: exactly three digits, then a hyphen, then exactly three digits, then another hyphen, then exactly four digits.

Likewise, you can set upper or lower limits:

\d{5,10}

means "at least 5, but not more than 10 digits".

Update: The OP clarified that he's trying to limit the value, not the length. My new answer is don't use regular expressions for that. Extract the value, then compare it against the maximum you extracted from the size parameter. It's much less error-prone.

The issue is because your data source is not setup properly, to do that please verify your data source connection, in order to do that first navigate to Report Service Configuration Manager through

clicking on the start -> Start All -> Microsoft SQL Server ->Configuration Tool -> “Report Service Configuration Manager”

The open Report Manager URL and then navigate to the Data Source folder, see in the picture below

Then Create a Data Source or configure the one that is already there by right click on your database source and select "Manage" as is shown below

Now on the properties tab, on your left menu, fill out the data source with your connection string and username and password, after that click on test connection, and if the connection was successful, then click "Apply"

Navigate to the folder that contains your report in this case "SurveyLevelReport"

And Finally set your Report to the Data Source that you set up previously, and click Apply

You need to control the opening of sub forms from a main form.

In my case I'm opening a Login window first before I launch my form1. I control everything from Program.cs. Set up a validation flag in Program.cs. Open Login window from Program.cs. Control then goes to login window. Then if the validation is good, set the validation flag to true from the login window. Now you can safely close the login window. Control returns to Program.cs. If the validation flag is true, open form1. If the validation flag is false, your application will close.

In Program.cs:

   static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        /// 

        //Validation flag
        public static bool ValidLogin = false;

        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);


            Application.Run(new Login());

            if (ValidLogin)
            {
                Application.Run(new Form1());
            }
        }

    }

In Login.cs:

       private void btnOK_Click(object sender, EventArgs e)
        {
            if (txtUsername.Text == "x" && txtPassword.Text == "x")
            {
                Program.ValidLogin = true;
                this.Close();
            }
            else
            {
                MessageBox.Show("Username or Password are incorrect.");
            }
        }

        private void btnExit_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }

Found an easier way that works as well:

Color.parseColor(getString(R.color.idname);

From Apple Docs

You can use subscript syntax to retrieve a value from the dictionary for a particular key. Because it is possible to request a key for which no value exists, a dictionary’s subscript returns an optional value of the dictionary’s value type. If the dictionary contains a value for the requested key, the subscript returns an optional value containing the existing value for that key. Otherwise, the subscript returns nil:

https://developer.apple.com/documentation/swift/dictionary

if let airportName = airports["DUB"] {
    print("The name of the airport is \(airportName).")
} else {
    print("That airport is not in the airports dictionary.")
}
// prints "The name of the airport is Dublin Airport."

In order to parse a java.util.Date object you have to convert it to String first using your own format.

inActiveDate = format1.parse(  format1.format(date)  );

But I believe you are being redundant here.

check that your web.php file has this extension

use Illuminate\Support\Facades\Route;

my problem gone fixed by this way.

You can always do something like this:

update  mytable t
set     SomeColumn = c.ComputedValue
from    (select *, 42 as ComputedValue from mytable where id = 1) c
where t.id = c.id 

You can now also use with statement inside update

update  mytable t
set     SomeColumn = c.ComputedValue
from    (with abc as (select *, 43 as ComputedValue_new from mytable where id = 1
         select *, 42 as ComputedValue, abc.ComputedValue_new  from mytable n1
           inner join abc on n1.id=abc.id) c
where t.id = c.id 

You can use my plug-in to create tests easily:

1. highlight the method
2. press Ctrl+Alt+Shift+U
3. it will create the unit test for it.

The plug-in is available here. Hope this helps.

Maybe that's a bit shorter and easier to understand:

import re
text = '... someline abc... someother line... name my_user_name is valid.. some more lines'
>>> re.search('name (.*) is valid', text).group(1)
'my_user_name'

One way that you can do it is creating a new object in the module instead of replacing it.

for example:

var testone = function () {
    console.log('test one');
};
var testTwo = function () {
    console.log('test two');
};
module.exports.testOne = testOne;
module.exports.testTwo = testTwo;

and to call

var test = require('path_to_file').testOne:
testOne();

If you combine both Ben and ausadmin's solutions, you end up with a very MVVM friendly solution:

<TextBox Text="{Binding Txt1, Mode=TwoWay, UpdateSourceTrigger=Explicit}">
    <TextBox.InputBindings>
        <KeyBinding Gesture="Enter" 
                    Command="{Binding UpdateTextBoxBindingOnEnterCommand}"
                    CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}" />
    </TextBox.InputBindings>
</TextBox>

...which means you are passing the TextBox itself as the parameter to the Command.

This leads to your Command looking like this (if you're using a DelegateCommand-style implementation in your VM):

    public bool CanExecuteUpdateTextBoxBindingOnEnterCommand(object parameter)
    {
        return true;
    }

    public void ExecuteUpdateTextBoxBindingOnEnterCommand(object parameter)
    {
        TextBox tBox = parameter as TextBox;
        if (tBox != null)
        {
            DependencyProperty prop = TextBox.TextProperty;
            BindingExpression binding = BindingOperations.GetBindingExpression(tBox, prop);
            if (binding != null) 
                binding.UpdateSource();
        }
    }

This Command implementation can be used for any TextBox and best of all no code in the code-behind though you may want to put this in it's own class so there are no dependencies on System.Windows.Controls in your VM. It depends on how strict your code guidelines are.

<?php

    header('Content-type: text/plain');
    header('Content-Disposition: attachment;

    /*

    */
    echo $content;
?>

getline is storing the entire line at once, which is not what you want. A simple fix is to have three variables and use cin to get them all. C++ will parse automatically at the spaces.

#include <iostream>
using namespace std;

int main() {
    string a, b, c;
    cin >> a >> b >> c;
    //now you have your three words
    return 0;
}

I don't know what particular "operation" you're talking about, so I can't help you there, but if it's changing characters, read up on string and indices. The C++ documentation is great. As for using namespace std; versus std:: and other libraries, there's already been a lot said. Try these questions on StackOverflow to start.

First, I don't understand why you are adding all the keys and values count times, Index is never used.

I tried this example :

        var source = new BindingSource();
        List<MyStruct> list = new List<MyStruct> { new MyStruct("fff", "b"),  new MyStruct("c","d") };
        source.DataSource = list;
        grid.DataSource = source;

and that work pretty well, I get two columns with the correct names. MyStruct type exposes properties that the binding mechanism can use.

    class MyStruct
   {
    public string Name { get; set; }
    public string Adres { get; set; }


    public MyStruct(string name, string adress)
    {
        Name = name;
        Adres = adress;
    }
  }

Try to build a type that takes one key and value, and add it one by one. Hope this helps.

If you are using Express as back-end you just have to install cors and import and use it in app.use(cors());. If it is not resolved then try switching ports. It will surely resolve after switching ports

Using pygame on any platform

The advantage of using pygame is that it can be made to work on any OS platform. Below example code is for GNU/Linux though.

First install the pygame module for python3 as explained in detail here.

$ sudo pip3 install pygame

The pygame module can play .wav and .ogg files from any file location. Here is an example:

#!/usr/bin/env python3
import pygame
pygame.mixer.init()
sound = pygame.mixer.Sound('/usr/share/sounds/freedesktop/stereo/phone-incoming-call.oga')
sound.play()

  <beans:property name="passwordEncoder" ref="encoder" />
</beans:bean>
<!-- For hashing and salting user passwords -->
    <beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>

In java class

PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
String hashedPassword = passwordEncoder.encode(yourpassword);

This difference is due to the behavior of Promises more than fetch() specifically.

When a .then() callback returns an additional Promise, the next .then() callback in the chain is essentially bound to that Promise, receiving its resolve or reject fulfillment and value.

The 2nd snippet could also have been written as:

iterator.then(response =>
    response.json().then(post => document.write(post.title))
);

In both this form and yours, the value of post is provided by the Promise returned from response.json().

When you return a plain Object, though, .then() considers that a successful result and resolves itself immediately, similar to:

iterator.then(response =>
    Promise.resolve({
      data: response.json(),
      status: response.status
    })
    .then(post => document.write(post.data))
);

post in this case is simply the Object you created, which holds a Promise in its data property. The wait for that promise to be fulfilled is still incomplete.

Call getActivity() method inside the onActivityCreated()

Code posted by you is correct and should have worked. But check exactly what you have in the char*. If the correct value is to big to be represented, functions will return a positive or negative HUGE_VAL. Check what you have in the char* against maximum values that float and double can represent on your computer.

Check this page for strtod reference and this page for atof reference.

I have tried the example you provided in both Windows and Linux and it worked fine.

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

Try writing the following in the terminal:

sudo apt-get install python-tk

Don't forget to actually import Tkinter module at the beginning of your program:

import Tkinter

Best solution:

$('select').on('selectric-before-change', function (event, element, selectric) {
    var current = element.state.currValue; // index of current value before select a new one
    var selected = element.state.selectedIdx; // index of value that will be selected

    // choose what you need
    console.log(element.items[current].value);
    console.log(element.items[current].text);
    console.log(element.items[current].slug);
});

just use mysqldump -u root database table or if using with password mysqldump -u root -p pass database table

It's the '+' operator at the beginning of the line that trips things up (not just that you are using two '+' operators consecutively). The '+' operator can be used at the end of lines, but not at the beginning.

This works:

ggplot(combined.data, aes(x = region, y = expression, fill = species)) +
geom_boxplot() 

The does not:

ggplot(combined.data, aes(x = region, y = expression, fill = species))
+ geom_boxplot() 

*Error in + geom_boxplot():
invalid argument to unary operator*

You also can't use two '+' operators, which in this case you've done. But to fix this, you'll have to selectively remove those at the beginning of lines.

After looking for an answer for myself for some time, i could find something. in general if we are using it for just one property it appears same even if we do a "View Source" of generated HTML Below is generated HTML for example, when i want to display only Name property for my class

    <td>
    myClassNameProperty
    </td>
   <td>
    myClassNameProperty, This is direct from Item
    </td>

This is the generated HTML from below code

<td>
@Html.DisplayFor(modelItem=>item.Genre.Name)            
</td>

<td>
@item.Genre.Name, This is direct from Item
</td>

At the same time now if i want to display all properties in one statement for my class "Genre" in this case, i can use @Html.DisplayFor() to save on my typing, for least

i can write @Html.DisplayFor(modelItem=>item.Genre) in place of writing a separate statement for each property of Genre as below

@item.Genre.Name
@item.Genre.Id
@item.Genre.Description

and so on depending on number of properties.

Just a simplified version of @T.J. Crowder and @RegarBoy's answers.

Since this question was closed, I'm posting here for how you do it using SQLAlchemy. Via recursion, it retries a bulk insert or update to combat race conditions and validation errors.

First the imports

import itertools as it

from functools import partial
from operator import itemgetter

from sqlalchemy.exc import IntegrityError
from app import session
from models import Posts

Now a couple helper functions

def chunk(content, chunksize=None):
    """Groups data into chunks each with (at most) `chunksize` items.
    https://stackoverflow.com/a/22919323/408556
    """
    if chunksize:
        i = iter(content)
        generator = (list(it.islice(i, chunksize)) for _ in it.count())
    else:
        generator = iter([content])

    return it.takewhile(bool, generator)


def gen_resources(records):
    """Yields a dictionary if the record's id already exists, a row object 
    otherwise.
    """
    ids = {item[0] for item in session.query(Posts.id)}

    for record in records:
        is_row = hasattr(record, 'to_dict')

        if is_row and record.id in ids:
            # It's a row but the id already exists, so we need to convert it 
            # to a dict that updates the existing record. Since it is duplicate,
            # also yield True
            yield record.to_dict(), True
        elif is_row:
            # It's a row and the id doesn't exist, so no conversion needed. 
            # Since it's not a duplicate, also yield False
            yield record, False
        elif record['id'] in ids:
            # It's a dict and the id already exists, so no conversion needed. 
            # Since it is duplicate, also yield True
            yield record, True
        else:
            # It's a dict and the id doesn't exist, so we need to convert it. 
            # Since it's not a duplicate, also yield False
            yield Posts(**record), False

And finally the upsert function

def upsert(data, chunksize=None):
    for records in chunk(data, chunksize):
        resources = gen_resources(records)
        sorted_resources = sorted(resources, key=itemgetter(1))

        for dupe, group in it.groupby(sorted_resources, itemgetter(1)):
            items = [g[0] for g in group]

            if dupe:
                _upsert = partial(session.bulk_update_mappings, Posts)
            else:
                _upsert = session.add_all

            try:
                _upsert(items)
                session.commit()
            except IntegrityError:
                # A record was added or deleted after we checked, so retry
                # 
                # modify accordingly by adding additional exceptions, e.g.,
                # except (IntegrityError, ValidationError, ValueError)
                db.session.rollback()
                upsert(items)
            except Exception as e:
                # Some other error occurred so reduce chunksize to isolate the 
                # offending row(s)
                db.session.rollback()
                num_items = len(items)

                if num_items > 1:
                    upsert(items, num_items // 2)
                else:
                    print('Error adding record {}'.format(items[0]))

Here's how you use it

>>> data = [
...     {'id': 1, 'text': 'updated post1'}, 
...     {'id': 5, 'text': 'updated post5'}, 
...     {'id': 1000, 'text': 'new post1000'}]
... 
>>> upsert(data)

The advantage this has over bulk_save_objects is that it can handle relationships, error checking, etc on insert (unlike bulk operations).

From the documentation:

If the pattern does not contain a slash /, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore file (relative to the toplevel of the work tree if not from a .gitignore file).

A leading slash matches the beginning of the pathname. For example, "/*.c" matches "cat-file.c" but not "mozilla-sha1/sha1.c".

So you should add the following line to your root .gitignore:

/config.php

We can emulate a do-while loop in Bash with while [[condition]]; do true; done like this:

while [[ current_time <= $cutoff ]]
    check_if_file_present
    #do other stuff
do true; done

For an example. Here is my implementation on getting ssh connection in bash script:

#!/bin/bash
while [[ $STATUS != 0 ]]
    ssh-add -l &>/dev/null; STATUS="$?"
    if [[ $STATUS == 127 ]]; then echo "ssh not instaled" && exit 0;
    elif [[ $STATUS == 2 ]]; then echo "running ssh-agent.." && eval `ssh-agent` > /dev/null;
    elif [[ $STATUS == 1 ]]; then echo "get session identity.." && expect $HOME/agent &> /dev/null;
    else ssh-add -l && git submodule update --init --recursive --remote --merge && return 0; fi
do true; done

It will give the output in sequence as below:

Step #0 - "gcloud": intalling expect..
Step #0 - "gcloud": running ssh-agent..

I was facing the same error for 2 days, then finally I found a solution. I checked for all the installed connectors using pip list and uninstalled all the connectors. In my case they were:

1. mysql-connector
2. mysql-connector-python
3. mysql-connector-python-rf

Uninstalled them using pip uninstall mysql-connector and finally downloaded and installed the mysql-connector-python from MySQL official website and it works well.

Since chrome has come up with the multiple profiles you will not get it directly in C:\Users\<Your_User_Name>\AppData\Local\Google\Chrome\User Data\Default\Extensions but you have to first type chrome://version/ in a tab and then look out for Profile path inside that and after you reach to your profile path look for Extensions folder in it and then folder with the desired extension Id

Go to the Config button (up right) and select the Autostart for Apache.

I think the author's of React Router (v4) just added that withRouter HOC to appease certain users. However, I believe the better approach is to just use render prop and make a simple PropsRoute component that passes those props. This is easier to test as you it doesn't "connect" the component like withRouter does. Have a bunch of nested components wrapped in withRouter and it's not going to be fun. Another benefit is you can also use this pass through whatever props you want to the Route. Here's the simple example using render prop. (pretty much the exact example from their website https://reacttraining.com/react-router/web/api/Route/render-func) (src/components/routes/props-route)

import React from 'react';
import { Route } from 'react-router';

export const PropsRoute = ({ component: Component, ...props }) => (
  <Route
    { ...props }
    render={ renderProps => (<Component { ...renderProps } { ...props } />) }
  />
);

export default PropsRoute;

usage: (notice to get the route params (match.params) you can just use this component and those will be passed for you)

import React from 'react';
import PropsRoute from 'src/components/routes/props-route';

export const someComponent = props => (<PropsRoute component={ Profile } />);

also notice that you could pass whatever extra props you want this way too

<PropsRoute isFetching={ isFetchingProfile } title="User Profile" component={ Profile } />

CATALINA_BASE is optional.

However, in the following scenarios it helps to setup CATALINA_BASE that is separate from CATALINA_HOME.

1. When more than 1 instances of tomcat are running on same host

   • This helps have only 1 runtime of tomcat installation, with multiple CATALINA_BASE server configurations running on separate ports.
   • If any patching, or version upgrade needs be, only 1 installation changes required, or need to be tested/verified/signed-off.

2. Separation of concern (Single responsibility)

   • Tomcat runtime is standard and does not change during every release process. i.e. Tomcat binaries
   • Release process may add more stuff as webapplication (webapps folder), environment configuration (conf directory), logs/temp/work directory

select 
    count(1) "NO. Of DB Users", 
    to_char(sysdate,'DD-MON-YYYY:HH24:MI:SS') sys_time
from 
    v$session 
where 
    username is NOT  NULL;

Use this instead:

<input id='tea-submit' type='submit' name = 'submit'    value = 'Tea'>
<input id='coffee-submit' type='submit' name = 'submit' value = 'Coffee'>

To be able to pass the select, I just set it back to :

  $('#selectID').prop('disabled',false);

or

  $('#selectID').attr('disabled',false);

when passing the request.

What I have done with no memory leaks or lint warnings is to use @f.trajkovski's method, but instead of using MainActivity, use WeakReference<MainActivity> instead.

public class MainActivity extends AppCompatActivity {
public static WeakReference<MainActivity> weakActivity;
// etc..
 public static MainActivity getmInstanceActivity() {
    return weakActivity.get();
}
}

Then in MainActivity OnCreate()

weakActivity = new WeakReference<>(MainActivity.this);

Then in another class

MainActivity.getmInstanceActivity().yourMethod();

Works like a charm

In my case it had to do with not having installed previously the GDAL core. For a guide on how to install the GDAL and Basemap libraries go to: https://github.com/felipunky/GISPython/blob/master/README.md

I suspect you would just want to grab a few columns from V$SESSION and the SQL statement from V$SQL. Assuming you want to exclude the background processes that Oracle itself is running

SELECT sess.process, sess.status, sess.username, sess.schemaname, sql.sql_text
  FROM v$session sess,
       v$sql     sql
 WHERE sql.sql_id(+) = sess.sql_id
   AND sess.type     = 'USER'

The outer join is to handle those sessions that aren't currently active, assuming you want those. You could also get the sql_fulltext column from V$SQL which will have the full SQL statement rather than the first 1000 characters, but that is a CLOB and so likely a bit more complicated to deal with.

Realistically, you probably want to look at everything that is available in V$SESSION because it's likely that you can get a lot more information than SP_WHO provides.

I am running Windows 7 and using git as setup by following the instructions on GitHub (a year or two back). A rather common use-case I would have thought. None of the answers above helped me, and after much frustration I eventually found my 'real' gitconfig file in the following directory;

C:\Users\Bill\AppData\Local\GitHub\PortableGit_054f2e797ebafd44a30203088cd 3d58663c627ef\etc

Obviously substitute your user name and presumably the suffix after PortableGit_ is a unique GUID or similar.

I found a solution to my issue and after a request, will post it here to help others. Apologies if I missed any details, it's been a while since I worked on this solution.

The first thing that is required is to install Openoffice.org on the server. I requested my hosting provider to install the open office RPM on my VPS. This can be done through WHM directly.

Now that the server has the capability to handle MS Office files you are able to convert the files by executing command line instructions via PHP. To handle this, I found PyODConverter: https://github.com/mirkonasato/pyodconverter

I created a directory on the server and placed the PyODConverter python file within it. I also created a plain text file above the web root (I named it "adocpdf"), with the following command line instructions in it:

directory=$1
filename=$2
extension=$3
SERVICE='soffice'
if [ "`ps ax|grep -v grep|grep -c $SERVICE`" -lt 1 ]; then 
unset DISPLAY
/usr/bin/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard & 
sleep 5s
fi
python /home/website/python/DocumentConverter.py /home/website/$directory$filename$extension /home/website/$directory$filename.pdf

This checks that the openoffice.org libraries are running and then calls the PyODConverter script to process the file and output it as a PDF. The 3 variables on the first three lines are provided when the script is executed from with a PHP file. The delay ("sleep 5s") is used to ensure that openoffice.org has enough to time to initiate if required. I have used this for months now and the 5s gap seems to give enough breathing room.

The script will create a PDF version of the document in the same directory as the original.

Finally, initiating the conversion of a Word / Excel file from within PHP (I have it within a function that checks if the file we are dealing with is a word / excel document)...

//use openoffice.org
$output = array();
$return_var = 0;
exec("/opt/adocpdf {$directory} {$filename} {$extension}", $output, $return_var);

This PHP function is called once the Word / Excel file has been uploaded to the server. The 3 variables in the exec() call relate directly to the 3 at the start of the plain text script above. Note that the $directory variable requires no leading forward slash if the file for conversion is within the web root.

OK, that's it! Hopefully this will be useful to someone and save them the difficulties and learning curve I faced.

Use TextureLoader to load a image as texture and then simply apply that texture to scene background.

 new THREE.TextureLoader();
     loader.load('https://images.pexels.com/photos/1205301/pexels-photo-1205301.jpeg' , function(texture)
                {
                 scene.background = texture;  
                });

Result:

I agree with the OP that it seems more natural and consistent to name and define the output columns in the same place (e.g. as is done with tidyverse's summarize in R), but a work-around in pandas for now is to create the new columns with desired names via assign before doing the aggregation:

data.assign(
    f=data['column1'],
    mean=data['column2'],
    std=data['column2']
).groupby('Country').agg(dict(f=sum, mean=np.mean, std=np.std)).reset_index()

(Using reset_index turns 'Country', 'f', 'mean', and 'std' all into regular columns with a separate integer index.)

You're missing a GROUP BY clause:

SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.

Here's an easier way:

sudo apt-get install maven

Found it in the manual

The mode parameter is used to specify the handling of untracked files. It is optional: it defaults to all, and if specified, it must be stuck to the option (e.g. -uno, but not -u no).

git status -uno

$scope.reloadstat = function () { $state.go($state.current, {}, {reload: true}); };

Flow allows interface specification, without having to convert your whole code base to TypeScript.

Interfaces are a way of breaking dependencies, while stepping cautiously within existing code.

C# 8.0 is the latest version of c#.it is supported only on .NET Core 3.x and newer versions. Many of the newest features require library and runtime features introduced in .NET Core 3.x

First of all, shouldn't there be a CustomerId in the Invoices table? As it is, You can't perform this query for Invoices that have no payments on them as yet. If there are no payments on an invoice, that invoice will not even show up in the ouput of the query, even though it's an outer join...

Also, When a customer makes a payment, how do you know what Invoice to attach it to ? If the only way is by the InvoiceId on the stub that arrives with the payment, then you are (perhaps inappropriately) associating Invoices with the customer that paid them, rather than with the customer that ordered them... . (Sometimes an invoice can be paid by someone other than the customer who ordered the services)

For a fully transparent background use:

background: transparent;

Otherwise for a semi-transparent color fill use:

background: rgba(255,255,255,0.5); // or hsla(0, 0%, 100%, 0.5)

where the values are:

background: rgba(red,green,blue,opacity); // or hsla(hue, saturation, lightness, opacity)

You can also use rgba values for gradient backgrounds.

To get transparency on an image background simply reduce the opacity of the image in an image editor of you choice beforehand.

Jonathon's answer is better, but to let you know somelist[-1] is one of the LastIndexOf notations available.

As krusty.ar mentioned somelist.last apparently is too.

irb(main):003:0* f = 'C:\\path\\file.txt'
irb(main):007:0> f.split('\\')
=> ["C:", "path", "file.txt"]
irb(main):008:0> f.split('\\')[-1]
=> "file.txt"

My 2 cents here (even when there are a lot of cool/working responses)

I created this alias in my .gitconfig

[alias]
 ...
 conflicts = !git diff --name-only --diff-filter=U | grep -oE '[^/ ]+$'

which is going to show me just the names of the files with conflicts... not their whole path :)

This one has been answered already here: Python memory profiler

How about storing the new options in a variable, and then using .html(variable) to replace the data in the container?

I had a table that had a circular relationship with others and i was getting the same error. Turns out it is about the foreign key which was not nullable. If key is not nullable related object must be deleted and circular relations doesnt allow that. So use nullable foreign key.

[ForeignKey("StageId")]
public virtual Stage Stage { get; set; }
public int? StageId { get; set; }

As much as I love XAML, for this kinds of tasks I switch to code behind. Attached behaviors are a good pattern for this. Keep in mind, Expression Blend 3 provides a standard way to program and use behaviors. There are a few existing ones on the Expression Community Site.

Be careful if you really want to "change" the data type. Like in other cases (e.g. changing the iterator in a for loop) this might bring up unexpected behaviour:

>> dct = {1:3, 2:1}
>> len(str(dct))
12
>> print(str(dct))
{1: 31, 2: 0}
>> l = ["all","colours"]
>> len(str(l))
