You could initialize discount to 0 as long as your code is guaranteed not to try and use it before it is initialized. That would remove one check I suppose, I can't think of anything else.

In the file you include, wrap the html in a function.

<?php function($myVar) {?>
    <div>
        <?php echo $myVar; ?>
    </div>
<?php } ?>

In the file where you want it to be included, include the file and then call the function with the parameters you want.

Any JS code which executes and deals with DOM elements should execute after the DOM elements have been created. JS code is interpreted from top to down as layed out in the HTML. So, if there is a tag before the DOM elements, the JS code within script tag will execute as the browser parses the HTML page.

So, in your case, you can put your DOM interacting code inside a function so that only function is defined but not executed.

Then you can add an event listener for document load to execute the function.

That will give you something like:

<script>
  function init() {
    var myButton = document.getElementById("myButton");
    var myTextfield = document.getElementById("myTextfield");
    myButton.onclick = function() {
      var userName = myTextfield.value;
      greetUser(userName);
    }
  }

  function greetUser(userName) {
    var greeting = "Hello " + userName + "!";
    document.getElementsByTagName ("h2")[0].innerHTML = greeting;
  }

  document.addEventListener('readystatechange', function() {
    if (document.readyState === "complete") {
      init();
    }
  });

</script>
<h2>Hello World!</h2>
<p id="myParagraph">This is an example website</p>

<form>
  <input type="text" id="myTextfield" placeholder="Type your name" />
  <input type="button" id="myButton" value="Go" />
</form>

Since you're using express, just add bodyParser:

app.use(express.bodyParser());

then your route automatically has access to the uploaded file(s) in req.files:

app.post('/todo/create', function (req, res) {
    // TODO: move and rename the file using req.files.path & .name)
    res.send(console.dir(req.files));  // DEBUG: display available fields
});

If you name the input control "todo" like this (in Jade):

form(action="/todo/create", method="POST", enctype="multipart/form-data")
    input(type='file', name='todo')
    button(type='submit') New

Then the uploaded file is ready by the time you get the path and original filename in 'files.todo':

• req.files.todo.path, and
• req.files.todo.name

other useful req.files properties:

• size (in bytes)
• type (e.g., 'image/png')
• lastModifiedate
• _writeStream.encoding (e.g, 'binary')

If you want to "code golf" you can make a shorter version of some of the other answers here:

const sleep = ms => new Promise(resolve => setTimeout(resolve, ms));

But really the ideal answer in my opinion is to use Node's util library and its promisify function, which is designed for exactly this sort of thing (making promise-based versions of previously existing non-promise-based stuff):

const util = require('util');
const sleep = util.promisify(setTimeout);

In either case you can then pause simply by using await to call your sleep function:

await sleep(1000); // sleep for 1s/1000ms

You can't.

Well, of course you could, however an int (System.Int32) is not big enough to hold every possible decimal value.

That means if you cast a decimal that's larger than int.MaxValue you will overflow, and if the decimal is smaller than int.MinValue, it will underflow.

What happens when you under/overflow? One of two things. If your build is unchecked (i.e., the CLR doesn't care if you do), your application will continue after the value over/underflows, but the value in the int will not be what you expected. This can lead to intermittent bugs and may be hard to fix. You'll end up your application in an unknown state which may result in your application corrupting whatever important data its working on. Not good.

If your assembly is checked (properties->build->advanced->check for arithmetic overflow/underflow or the /checked compiler option), your code will throw an exception when an under/overflow occurs. This is probably better than not; however the default for assemblies is not to check for over/underflow.

The real question is "what are you trying to do?" Without knowing your requirements, nobody can tell you what you should do in this case, other than the obvious: DON'T DO IT.

If you specifically do NOT care, the answers here are valid. However, you should communicate your understanding that an overflow may occur and that it doesn't matter by wrapping your cast code in an unchecked block

unchecked
{
  // do your conversions that may underflow/overflow here
}

That way people coming behind you understand you don't care, and if in the future someone changes your builds to /checked, your code won't break unexpectedly.

If all you want to do is drop the fractional portion of the number, leaving the integral part, you can use Math.Truncate.

decimal actual = 10.5M;
decimal expected = 10M;
Assert.AreEqual(expected, Math.Truncate(actual));

Just declare a function

Size screenSize() {
return MediaQuery.of(context).size;
}

Use like below

return Container(
      width: screenSize().width,
      height: screenSize().height,
      child: ...
 )

After creating your client specifying the binding and endpoint address, you can assign an OperationTimeout,

client.InnerChannel.OperationTimeout = new TimeSpan(0, 5, 0);

The working solution listed are great, but the problem occurs when you want multiple default home for your git-bash.

A simple workaround is to start git-bash using bat script.

git-bash-to-htdocs.bat

cd C:\xampp\htdocs
"C:\Program Files\Git\git-bash.exe" 

The above of course assume git-bash is installed at C:\Program Files\Git\git-bash.exe

You can create multiple .bat file so your git-bash can start where it want to be

// Step 1, update your constraint
self.myOutletToConstraint.constant = 50; // New height (for example)

// Step 2, trigger animation
[UIView animateWithDuration:2.0 animations:^{

    // Step 3, call layoutIfNeeded on your animated view's parent
    [self.view layoutIfNeeded];
}];

There's still no simple answer. It depends on your scenario. MSDN has documentation to help you decide.

There are other options covered here. Instead of storing in the file system directly or in a BLOB, you can use the FileStream or File Table in SQL Server 2012. The advantages to File Table seem like a no-brainier (but admittedly I have no personal first-hand experience with them.)

The article is definitely worth a read.

You can install some git aliases to make this process simpler. This edits the [alias] node of your .gitconfig file.

git config --global alias.ignore 'update-index --skip-worktree'
git config --global alias.unignore 'update-index --no-skip-worktree'
git config --global alias.ignored '!git ls-files -v | grep "^S"'

The shortcuts this installs for you are as follows:

• git ignore config.xml
  • git will pretend that it doesn't see any changes upon config.xml — preventing you from accidentally committing those changes.
• git unignore config.xml
  • git will resume acknowledging your changes to config.xml — allowing you again to commit those changes.
• git ignored
  • git will list all the files which you are "ignoring" in the manner described above.

I built these by referring to phatmann's answer — which presents an --assume-unchanged version of the same.

The version I present uses --skip-worktree for ignoring local changes. See Borealid's answer for a full explanation of the difference, but essentially --skip-worktree's purpose is for developers to change files without the risk of committing their changes.

The git ignored command presented here uses git ls-files -v, and filters the list to show just those entries beginning with the S tag. The S tag denotes a file whose status is "skip worktree". For a full list of the file statuses shown by git ls-files: see the documentation for the -t option on git ls-files.

I am not sure, but maybe this logic would work.

var d = 10;
var prevDate = "";
var x = 0;
var oldVal = "";
var func = function (d) {
    if (x == 0 && d != prevDate && prevDate == "") {

        prevDate = d;
    }
    else if (x == 1 && prevDate != d) {
        oldVal = prevDate;
        prevDate = d;
    }
    console.log(oldVal);
    x = 1;
};

Related information, especially if you are using NTVS for working with the Visual Studio IDE. The NTVS adds both NodeJS and Express tools, scaffolding, project templates to Visual Studio 2012, 2013.

Also, the verbiage that calls ExpressJS or Connect as a "WebServer" is incorrect. You can create a basic WebServer with or without them. A basic NodeJS program can also use the http module to handle http requests, Thus becoming a rudimentary web server.

You just need to enable the tooltip:

Just had this problem on Indigo SR2. It popped up after I removed a superfluous jar from the classpath (build path). Restarting Eclipse didn't help. Added back the jar to the build path...error went away. Removed the jar once again, and this time I was spared from another complaint.

you should try this

g++-4.4 -std=c++0x or g++-4.7 -std=c++0x

Next, you have to create the .pfx file that you will use to sign your deployments. Open a Command Prompt window, and type the following command:

PVK2PFX –pvk yourprivatekeyfile.pvk –spc yourcertfile.cer –pfx yourpfxfile.pfx –po yourpfxpassword

where:

• pvk - yourprivatekeyfile.pvk is the private key file that you created in step 4.
• spc - yourcertfile.cer is the certificate file you created in step 4.
• pfx - yourpfxfile.pfx is the name of the .pfx file that will be creating.
• po - yourpfxpassword is the password that you want to assign to the .pfx file. You will be prompted for this password when you add the .pfx file to a project in Visual Studio for the first time.

(Optionally (and not for the OP, but for future readers), you can create the .cer and .pvk file from scratch) (you would do this BEFORE the above). Note the mm/dd/yyyy are placeholders for start and end dates. see msdn article for full documentation.

makecert -sv yourprivatekeyfile.pvk -n "CN=My Certificate Name" yourcertfile.cer -b mm/dd/yyyy -e mm/dd/yyyy -r

I modified the above function to account for carriage returns in IE. It's untested but I did something similar with it in my code so it should be workable.

function getCaret(el) {
  if (el.selectionStart) { 
    return el.selectionStart; 
  } else if (document.selection) { 
    el.focus(); 

    var r = document.selection.createRange(); 
    if (r == null) { 
      return 0; 
    } 

    var re = el.createTextRange(), 
    rc = re.duplicate(); 
    re.moveToBookmark(r.getBookmark()); 
    rc.setEndPoint('EndToStart', re); 

    var add_newlines = 0;
    for (var i=0; i<rc.text.length; i++) {
      if (rc.text.substr(i, 2) == '\r\n') {
        add_newlines += 2;
        i++;
      }
    }

    //return rc.text.length + add_newlines;

    //We need to substract the no. of lines
    return rc.text.length - add_newlines; 
  }  
  return 0; 
}

DTU is nothing but a blend of CPU, memory and IO. Why do we need a blend when these 3 are pretty clear? Because we want a unit for power. But it is still confusing in many ways. eg: If I simply increase memory will it increase power(DTU)? If yes, how can DTU be a blend? It is a yes. In this memory-increase case, as per the query in the answer given by jyong, DTU will be equivalent to memory(since we increased it). MS has even a pricing model based on this DTU and it raised many questions.

Because of these confusions and questions, MS wanted to bring in another option. We already had some specs in on-premise, why can't we use them? As a result, 'vCore pricing model' was born. In this model we have visibility to RAM and CPU. But not in DTU model.

The counter argument from DTU would be that DTU measures are calibrated using a benchmark that simulates real-world database workload. And that we are not in on-premise anymore ;). Yes it is designed with cloud computing in mind(but is also used in OLTP workloads).

But that is not all. Now that we are entering the pricing model the equation changes. The question now is about money and the bundle(what all features are included). Here DTU has some advantages(the way I see it) but enterprises with many existing licenses would disagree.

• DTU has one pricing(Compute + Storage + Backup). Simpler and can start with lower pricing.
• vCore has different pricing (Compute, Storage). Software assurance is available here. Enterprises will have on-premise licenses, this can be easily ported here(so they get big machines for less price than DTU model). Plus they commit for multiple years and get additional discounts.

We can switch between both when needed so if not sure start with DTU(Basic/Standard/Premium).

How can we know which pricing tier to use? Go to configure menu as given below: (on the right/left you can switch between both)

Even though Vcore is bigger 'machine' and for bigger things, the cost can sometimes be cheaper for enterprise organizations. Here is a proof. DTU costs $147 . But Vcore costs $111. That is because you can commit for 3 years(but still pay monthly) and also because of the license re-use option(enterprises will have on-premise licenses).

It is a bit too much than answering direct question but I am gonna go ahead and make this complete by answering 'how to choose between different options in DTU let alone choosing between DTU and vCore'. This is answered in this beautiful blog and this flowchart explains it all

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

Variable for your timer

var timer = 60

NSTimer with 1.0 as interval

var clock = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: "countdown", userInfo: nil, repeats: true)

Here you can decrease the timer

func countdown() {
    timer--
}

This is the code to subtract one date from another. This example converts the dates to objects as the getTime() function won't work unless it's an Date object.

    var dat1 = document.getElementById('inputDate').value;
                var date1 = new Date(dat1)//converts string to date object
                alert(date1);
                var dat2 = document.getElementById('inputFinishDate').value;
                var date2 = new Date(dat2)
                alert(date2);

                var oneDay = 24 * 60 * 60 * 1000; // hours*minutes*seconds*milliseconds
                var diffDays = Math.abs((date1.getTime() - date2.getTime()) / (oneDay));
                alert(diffDays);

Try this:

/^stop.*$/

Explanation:

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

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

/^stop\s+.*$/

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

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

Most of the time, the problem is due to some error on the human side. In my case, I was using some classes whose names are similar. I have added the empty() method under one class; however, my code was calling the empty() method from another class. At that moment, the mind was stuck. I was running make clean, and remake thinking that it was some older version of the header got used. After walking away for a moment, I found that problem right away. We programmers tends to blame others first. Maybe we should insist on ourselves to be wrong first.

Sometimes, I forget to write the latest update to disk and looking at the correct version of the code, but the compiler is seeing the wrong version of the code. This situation may be less a issue on IDE (I use vi to do coding).

Using parseInt() is a bad idea mainly because it never fails. Also because some results can be unexpected, like in the case of INFINITY.
Below is the function for handling unexpected behaviour.

function cleanInt(x) {
    x = Number(x);
    return x >= 0 ? Math.floor(x) : Math.ceil(x);
}

See results of below test cases.

console.log("CleanInt: ", cleanInt('xyz'), " ParseInt: ", parseInt('xyz'));
console.log("CleanInt: ", cleanInt('123abc'), " ParseInt: ", parseInt('123abc'));
console.log("CleanInt: ", cleanInt('234'), " ParseInt: ", parseInt('234'));
console.log("CleanInt: ", cleanInt('-679'), " ParseInt: ", parseInt('-679'));
console.log("CleanInt: ", cleanInt('897.0998'), " ParseInt: ", parseInt('897.0998'));
console.log("CleanInt: ", cleanInt('Infinity'), " ParseInt: ", parseInt('Infinity'));

result:

CleanInt:  NaN  ParseInt:  NaN
CleanInt:  NaN  ParseInt:  123
CleanInt:  234  ParseInt:  234
CleanInt:  -679  ParseInt:  -679
CleanInt:  897  ParseInt:  897
CleanInt:  Infinity  ParseInt:  NaN

fileURLWithPath() is used to convert a plain file path (e.g. "/path/to/file") to an URL. Your urlString is a full URL string including the scheme, so you should use

let url = NSURL(string: urlstring)

to convert it back to NSURL. Example:

let urlstring = "file:///Users/Me/Desktop/Doc.txt"
let url = NSURL(string: urlstring)
println("the url = \(url!)")
// the url = file:///Users/Me/Desktop/Doc.txt

The usual rule for casting to a bool is that a few special literals (False, 0, 0.0, (), [], {}) are false and then everything else is true, so I recommend the following:

def boolify(val):
    if (isinstance(val, basestring) and bool(val)):
        return not val in ('False', '0', '0.0')
    else:
        return bool(val)

I know it's late, but maybe this helps others. I have created a class NotifyObservableCollection, that solves the problem of missing notification to item itself, when a property of the item changes. The usage is as simple as ObservableCollection.

public class NotifyObservableCollection<T> : ObservableCollection<T> where T : INotifyPropertyChanged
{
    private void Handle(object sender, PropertyChangedEventArgs args)
    {
        OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset, null));
    }

    protected override void OnCollectionChanged(NotifyCollectionChangedEventArgs e)
    {
        if (e.NewItems != null) {
            foreach (object t in e.NewItems) {
                ((T) t).PropertyChanged += Handle;
            }
        }
        if (e.OldItems != null) {
            foreach (object t in e.OldItems) {
                ((T) t).PropertyChanged -= Handle;
            }
        }
        base.OnCollectionChanged(e);
    }

While Items are added or removed the class forwards the items PropertyChanged event to the collections PropertyChanged event.

usage:

public abstract class ParameterBase : INotifyPropertyChanged
{
    protected readonly CultureInfo Ci = new CultureInfo("en-US");
    private string _value;

    public string Value {
        get { return _value; }
        set {
            if (value == _value) return;
            _value = value;
            OnPropertyChanged();
        }
    }
}

public class AItem {
    public NotifyObservableCollection<ParameterBase> Parameters {
        get { return _parameters; }
        set {
            NotifyCollectionChangedEventHandler cceh = (sender, args) => OnPropertyChanged();
            if (_parameters != null) _parameters.CollectionChanged -= cceh;
            _parameters = value;
            //needed for Binding to AItem at xaml directly
            _parameters.CollectionChanged += cceh; 
        }
    }

    public NotifyObservableCollection<ParameterBase> DefaultParameters {
        get { return _defaultParameters; }
        set {
            NotifyCollectionChangedEventHandler cceh = (sender, args) => OnPropertyChanged();
            if (_defaultParameters != null) _defaultParameters.CollectionChanged -= cceh;
            _defaultParameters = value;
            //needed for Binding to AItem at xaml directly
            _defaultParameters.CollectionChanged += cceh;
        }
    }


public class MyViewModel {
    public NotifyObservableCollection<AItem> DataItems { get; set; }
}

If now a property of an item in DataItems changes, the following xaml will get a notification, though it binds to Parameters[0] or to the item itself except to the changing property Value of the item (Converters at Triggers are called reliable on every change).

<DataGrid CanUserAddRows="False" AutoGenerateColumns="False" ItemsSource="{Binding DataItems}">
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding Parameters[0].Value}" Header="P1">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="Background" Value="Aqua" />
                    <Style.Triggers>
                        <DataTrigger Value="False">
                            <!-- Bind to Items with changing properties -->
                            <DataTrigger.Binding>
                                <MultiBinding Converter="{StaticResource ParameterCompareConverter}">
                                    <Binding Path="DefaultParameters[0]" />
                                    <Binding Path="Parameters[0]" />
                                </MultiBinding>
                            </DataTrigger.Binding>
                            <Setter Property="Background" Value="DeepPink" />
                        </DataTrigger>
                        <!-- Binds to AItem directly -->
                        <DataTrigger Value="True" Binding="{Binding Converter={StaticResource CheckParametersConverter}}">
                            <Setter Property="FontWeight" Value="ExtraBold" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>

This should get your sorted:

• Highlight from the end of the first line, to the very beginning of the third line.
• Use the Ctrl + H to bring up the 'Find and Replace' window.
• The highlighed region will already be plased in the 'Find' textbox.
• Replace with: \r\n
• 'Replace All' will then remove all the additional line spaces not required.

Here's how it should look:

Please read this: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx
You should set indicies for your html elements "name" attributes like planCompareViewModel[0].PlanId, planCompareViewModel[1].PlanId to make binder able to parse them into IEnumerable.
Instead of @foreach (var planVM in Model) use for loop and render names with indexes.

Sam's answer gives the reason that default arguments are preferable for constructors rather than overloading. I just want to add that C++-0x will allow delegation from one constructor to another, thereby removing the need for defaults.

t indicates for text mode

https://docs.python.org/release/3.1.5/library/functions.html#open

on linux, there's no difference between text mode and binary mode, however, in windows, they converts \n to \r\n when text mode.

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

# keras library import  for Saving and loading model and weights

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

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


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

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

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

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

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

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

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

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

To predict for different data you can use this

loaded_model.predict_classes("your_test_data here")

Use the constants defined in the math package:

const (
    MaxInt8   = 1<<7 - 1
    MinInt8   = -1 << 7
    MaxInt16  = 1<<15 - 1
    MinInt16  = -1 << 15
    MaxInt32  = 1<<31 - 1
    MinInt32  = -1 << 31
    MaxInt64  = 1<<63 - 1
    MinInt64  = -1 << 63
    MaxUint8  = 1<<8 - 1
    MaxUint16 = 1<<16 - 1
    MaxUint32 = 1<<32 - 1
    MaxUint64 = 1<<64 - 1
)

After validation and before INSERT check if username already exists, using mysqli(procedural). This works:

//check if username already exists
       include 'phpscript/connect.php'; //connect to your database

       $sql = "SELECT username FROM users WHERE username = '$username'";
       $result = $conn->query($sql);

       if($result->num_rows > 0) {
           $usernameErr =  "username already taken"; //takes'em back to form
       } else { // go on to INSERT new record

This is how I accomplished reading a table in javascript. Basically I drilled down into the rows and then I was able to drill down into the individual cells for each row. This should give you an idea

//gets table
var oTable = document.getElementById('myTable');

//gets rows of table
var rowLength = oTable.rows.length;

//loops through rows    
for (i = 0; i < rowLength; i++){

   //gets cells of current row
   var oCells = oTable.rows.item(i).cells;

   //gets amount of cells of current row
   var cellLength = oCells.length;

   //loops through each cell in current row
   for(var j = 0; j < cellLength; j++){
      /* get your cell info here */
      /* var cellVal = oCells.item(j).innerHTML; */
   }
}

font/woff2

For nginx add the following to the mime.types file:

font/woff2 woff2;

Old Answer

The mime type (sometime written as mimetype) for WOFF2 fonts has been proposed as application/font-woff2.

Also, if you refer to the spec (http://dev.w3.org/webfonts/WOFF2/spec/) you will see that font/woff2 is being discussed. I suspect that the filal mime type for all fonts will eventually be the more logical font/* (font/ttf, font/woff2 etc)...

N.B. WOFF2 is still in 'Working Draft' status -- not yet adopted officially.

Your question is based on a false premise.

Arrays are not a primitive type in Java, but they are not objects either ... "

In fact, all arrays in Java are objects¹. Every Java array type has java.lang.Object as its supertype, and inherits the implementation of all methods in the Object API.

... so are they passed by value or by reference? Does it depend on what the array contains, for example references or a primitive type?

Short answers: 1) pass by value, and 2) it makes no difference.

Longer answer:

Like all Java objects, arrays are passed by value ... but the value is the reference to the array. So, when you assign something to a cell of the array in the called method, you will be assigning to the same array object that the caller sees.

This is NOT pass-by-reference. Real pass-by-reference involves passing the address of a variable. With real pass-by-reference, the called method can assign to its local variable, and this causes the variable in the caller to be updated.

But not in Java. In Java, the called method can update the contents of the array, and it can update its copy of the array reference, but it can't update the variable in the caller that holds the caller's array reference. Hence ... what Java is providing is NOT pass-by-reference.

Here are some links that explain the difference between pass-by-reference and pass-by-value. If you don't understand my explanations above, or if you feel inclined to disagree with the terminology, you should read them.

• http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/topic/com.ibm.xlcpp8a.doc/language/ref/cplr233.htm
• http://www.cs.fsu.edu/~myers/c++/notes/references.html

Related SO question:

• Is Java "pass-by-reference" or "pass-by-value"?

Historical background:

The phrase "pass-by-reference" was originally "call-by-reference", and it was used to distinguish the argument passing semantics of FORTRAN (call-by-reference) from those of ALGOL-60 (call-by-value and call-by-name).

• In call-by-value, the argument expression is evaluated to a value, and that value is copied to the called method.

• In call-by-reference, the argument expression is partially evaluated to an "lvalue" (i.e. the address of a variable or array element) that is passed to the calling method. The calling method can then directly read and update the variable / element.

• In call-by-name, the actual argument expression is passed to the calling method (!!) which can evaluate it multiple times (!!!). This was complicated to implement, and could be used (abused) to write code that was very difficult to understand. Call-by-name was only ever used in Algol-60 (thankfully!).

UPDATE

Actually, Algol-60's call-by-name is similar to passing lambda expressions as parameters. The wrinkle is that these not-exactly-lambda-expressions (they were referred to as "thunks" at the implementation level) can indirectly modify the state of variables that are in scope in the calling procedure / function. That is part of what made them so hard to understand. (See the Wikipedia page on Jensen's Device for example.)

^{1. Nothing in the linked Q&A (Arrays in Java and how they are stored in memory) either states or implies that arrays are not objects.}

Edit filename: core/Common.php, line number: 257

Before

return $_config[0] =& $config; 

After

$_config[0] =& $config;
return $_config[0]; 

Update

Added by NikiC

In PHP assignment expressions always return the assigned value. So $_config[0] =& $config returns $config - but not the variable itself, but a copy of its value. And returning a reference to a temporary value wouldn't be particularly useful (changing it wouldn't do anything).

Update

This fix has been merged into CI 2.2.1 (https://github.com/bcit-ci/CodeIgniter/commit/69b02d0f0bc46e914bed1604cfbd9bf74286b2e3). It's better to upgrade rather than modifying core framework files.

I have a feeling that the username and password that you are sending should be part of the Authorization Header. So the code below shows you how to create the Base64 string of the username and password. I also included an example of sending the POST data. In my case it was a phone_number parameter.

string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(_username + ":" + _password));

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Request);
webRequest.Headers.Add("Authorization", string.Format("Basic {0}", credentials));
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = WebRequestMethods.Http.Post;
webRequest.AllowAutoRedirect = true;
webRequest.Proxy = null;

string data = "phone_number=19735559042"; 
byte[] dataStream = Encoding.UTF8.GetBytes(data);

request.ContentLength = dataStream.Length;
Stream newStream = webRequest.GetRequestStream();
newStream.Write(dataStream, 0, dataStream.Length);
newStream.Close();

HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader streamreader = new StreamReader(stream);
string s = streamreader.ReadToEnd();

Your groups_main table has a key column named id. I believe you can only use the USING syntax for the join if the groups_fans table has a key column with the same name, which it probably does not. So instead, try this:

LEFT JOIN groups_fans AS m ON m.group_id = g.id

Or replace group_id with whatever the appropriate column name is in the groups_fans table.

To turn GPS on or off programatically you need 'root' access and BusyBox installed. Even with those, the task is not trivial.

I think that Aidan's answer is by far the best.

$('#yourgrid').jqGrid("editCell", 0, 0, false);

This commits any current edits, giving you access to the real value. I prefer it because:

• You don't have to hard-code any cell references in.
  • It is particularly well suited to using getRowData() to get the entire grid, as it doesn't care which cell you've just been editing.
  • You're not trying to parse some markup generated by jqGrid which may change in future.
  • If the user is saving, then ending the edit session is likely the behaviour they would want anyway.

If you try using:

df[DATE_FIELD]=(pd.to_datetime(df[DATE_FIELD],***unit='s'***))

and receive an error :

"pandas.tslib.OutOfBoundsDatetime: cannot convert input with unit 's'"

This means the DATE_FIELD is not specified in seconds.

In my case, it was milli seconds - EPOCH time.

The conversion worked using below:

df[DATE_FIELD]=(pd.to_datetime(df[DATE_FIELD],unit='ms')) 

If that is one table and have nothing to do with this - the simplest solution can be copy&paste to notepad then copy&paste back to excel :P

@folex answer is right.

But it will fail if the tableView has more than one section displayed at a time.

-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
   if([indexPath isEqual:((NSIndexPath*)[[tableView indexPathsForVisibleRows] lastObject])]){
    //end of loading

 }
}

Try this command, it will purge all branches that have been merged to the develop branch.

for i in `git branch -r --merged origin/develop| grep origin | grep -v '>' \

do \
   git push origin $i --delete; \

Use moment js for any date operation.

console.log(moment("Sunday, February 28, 2010").format('MM/DD/YYYY'));

This often happens to me when I know there are changes on the remote master, so I try to merge them using git merge master. However, this doesn't merge with the remote master, but with your local master.

So before doing the merge, checkout master, and then git pull there. Then you will be able to merge the new changes into your branch.

                string BaseWindow = driver.CurrentWindowHandle;
                ReadOnlyCollection<string> handles = driver.WindowHandles;
                foreach (string handle in handles)
                {
                    if (handle != BaseWindow)
                    {
                        string title = driver.SwitchTo().Window(handle).Title;
                        Thread.Sleep(3000);
                        driver.SwitchTo().Window(handle).Title.Equals(title);
                        Thread.Sleep(3000);

By the rational of making everything multiplication I add the entry at the end of the list

    clc; clear all;
    V = rand(1024*1024*32,1);
    N = 10;
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.5 s
    tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 7.5 s
    tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 4.9 s
    tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 6.8 s
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.7 s
    tic; for i=1:N, d = 1/norm(V); V1 = V*d;end; toc % 4.9 s
    tic; for i=1:N, d = norm(V)^-1; V1 = V*d;end;toc % 4.4 s

Using change event you can do something like this:

var limit = 3;
$('input.single-checkbox').on('change', function(evt) {
   if($(this).siblings(':checked').length >= limit) {
       this.checked = false;
   }
});

Use json_encode() if possible (PHP 5.2+).

You should use Node.contains, since it's now standard and available in all browsers.

https://developer.mozilla.org/en-US/docs/Web/API/Node.contains

values()

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

values_list()

Returns a QuerySet that returns list of tuples, rather than model instances, when used as an iterable.

distinct()

distinct are used to eliminate the duplicate elements.

Example:

>>> list(Article.objects.values_list('id', flat=True)) # flat=True will remove the tuples and return the list   
[1, 2, 3, 4, 5, 6]

>>> list(Article.objects.values('id'))
[{'id':1}, {'id':2}, {'id':3}, {'id':4}, {'id':5}, {'id':6}]

Try this snippet of code:

String timeSettings = android.provider.Settings.System.getString(
                this.getContentResolver(),
                android.provider.Settings.System.AUTO_TIME);
        if (timeSettings.contentEquals("0")) {
            android.provider.Settings.System.putString(
                    this.getContentResolver(),
                    android.provider.Settings.System.AUTO_TIME, "1");
        }
        Date now = new Date(System.currentTimeMillis());
        Log.d("Date", now.toString());

Make sure to add permission in Manifest

<uses-permission android:name="android.permission.WRITE_SETTINGS"/>

To add to @DennisWilliamson comment above:

@VaibhavBajpai: Try this: response=$(curl --write-out \n%{http_code} --silent --output - servername) - the last line in the result will be the response code

You can then parse the response code from the response using something like the following, where X can signify a regex to mark the end of the response (using a json example here)

X='*\}'
code=$(echo ${response##$X})

You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.

If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

Instead of using cat and I/O redirection it might be useful to use tee instead:

tee newfile <<EOF
line 1
line 2
line 3
EOF

It's more concise, plus unlike the redirect operator it can be combined with sudo if you need to write to files with root permissions.

If the formula already exists in a cell you can fill it down as follows:

• Select the cell containing the formula and press CTRL+SHIFT+DOWN to select the rest of the column (CTRL+SHIFT+END to select up to the last row where there is data)
• Fill down by pressing CTRL+D
• Use CTRL+UP to return up

On Mac, use CMD instead of CTRL.

An alternative if the formula is in the first cell of a column:

• Select the entire column by clicking the column header or selecting any cell in the column and pressing CTRL+SPACE
• Fill down by pressing CTRL+D

There is no need for that, as you can use css 'writing-mode' with values 'vertical-lr' or 'vertical-rl' as desired.

.item {
  writing-mode: vertical-rl;
}

In case you want to pass in a block, say, for a glyphicon button, as in the following:

<%= link_to my_url, class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

Then passing querystrings params could be accomplished through:

<%= link_to url_for(params.merge(my_params: "value")), class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

Like what Amber says in her answer: create a function. In fact when you don't have to make classes if you have something like:

class Person(object):
    def __init__(self, arg1, arg2):
        self.arg1 = arg1
        self.arg2 = arg2

    def compute(self, other):
        """ Example of bad class design, don't care about the result """
        return self.arg1 + self.arg2 % other

Here you just have a function encapsulate in a class. This just make the code less readable and less efficient. In fact the function compute can be written just like this:

def compute(arg1, arg2, other):
     return arg1 + arg2 % other

You should use classes only if you have more than 1 function to it and if keep a internal state (with attributes) has sense. Otherwise, if you want to regroup functions, just create a module in a new .py file.

You might look this video (Youtube, about 30min), which explains my point. Jack Diederich shows why classes are evil in that case and why it's such a bad design, especially in things like API.
It's quite a long video but it's a must see.

Another solution that it is similar to those already exposed here is this one. Just before the closing body tag place this html:

<div id="resultLoading" style="display: none; width: 100%; height: 100%; position: fixed; z-index: 10000; top: 0px; left: 0px; right: 0px; bottom: 0px; margin: auto;">
    <div style="width: 340px; height: 200px; text-align: center; position: fixed; top: 0px; left: 0px; right: 0px; bottom: 0px; margin: auto; z-index: 10; color: rgb(255, 255, 255);">
        <div class="uil-default-css">
            <img src="/images/loading-animation1.gif" style="max-width: 150px; max-height: 150px; display: block; margin-left: auto; margin-right: auto;" />
        </div>
        <div class="loader-text" style="display: block; font-size: 18px; font-weight: 300;">&nbsp;</div>
    </div>
    <div style="background: rgb(0, 0, 0); opacity: 0.6; width: 100%; height: 100%; position: absolute; top: 0px;"></div>
</div>

Finally, replace .loader-text element's content on the fly on every navigation event and turn on the #resultloading div, note that it is initially hidden.

var showLoader = function (text) {
    $('#resultLoading').show();
    $('#resultLoading').find('.loader-text').html(text);
};

jQuery(document).ready(function () {
    jQuery(window).on("beforeunload ", function () {
        showLoader('Loading, please wait...');
    });
});

This can be applied to any html based project with jQuery where you don't know which pages of your administration area will take too long to finish loading.

The gif image is 176x176px but you can use any transparent gif animation, please take into account that the image size is not important as it will be maxed to 150x150px.

Also, the function showLoader can be called on an element's click to perform an action that will further redirect the page, that is why it is provided ad an individual function. i hope this can also help anyone.

for me this works

unicode(data).encode('utf-8')

Android handles transparency across views and drawables (including PNG images) natively, so the scenario you describe (a partially transparent ImageView in front of a Gallery) is certainly possible.

If you're having problems it may be related to either the layout or your image. I've replicated the layout you describe and successfully achieved the effect you're after. Here's the exact layout I used.

<RelativeLayout 
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/gallerylayout"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
  <Gallery
    android:id="@+id/overview"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
  />
  <ImageView
    android:id="@+id/navigmaske"
    android:background="#0000"      
    android:src="@drawable/navigmask"
    android:scaleType="fitXY"
    android:layout_alignTop="@id/overview"
    android:layout_alignBottom="@id/overview"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
  />
</RelativeLayout>

Note that I've changed the parent RelativeLayout to a height and width of fill_parent as is generally what you want for a main Activity. Then I've aligned the top and bottom of the ImageView to the top and bottom of the Gallery to ensure it's centered in front of it.

I've also explicitly set the background of the ImageView to be transparent.

As for the image drawable itself, if you put the PNG file somewhere for me to look at I can use it in my project and see if it's responsible.

Hadoop file system does not support appending data to the existing files. Although, you can load your CSV file into HDFS and tell Hive to treat it as an external table.

When your Android stuio/jre uses a differ version of java, you will receive this error. to solve it, just set Android studio/jre to your JAVA_HOME. and uninstall your own java.

One quick solution that came to mind :-

<input type="checkbox" id="markitem" name="markitem" value="1" onchange="GetMarkedItems(1)">
<label for="markitem" style="position:absolute; top:1px; left:165px;">&nbsp</label>
<!-- Fire the below javascript everytime the page reloads -->
<script type=text/javascript>
  document.getElementById("markitem").checked = false;
</script>
<!-- Tested on Latest FF, Chrome, Opera and IE. -->

You have the month and day swapped:

'%m/%d/%Y %H:%M:%S.%f'

28 will never fit in the range for the %m month parameter otherwise.

With %m and %d in the correct order parsing works:

>>> from datetime import datetime
>>> datetime.strptime('07/28/2014 18:54:55.099000', '%m/%d/%Y %H:%M:%S.%f')
datetime.datetime(2014, 7, 28, 18, 54, 55, 99000)

You don't need to add '000'; %f can parse shorter numbers correctly:

>>> datetime.strptime('07/28/2014 18:54:55.099', '%m/%d/%Y %H:%M:%S.%f')
datetime.datetime(2014, 7, 28, 18, 54, 55, 99000)

There are a couple of parallization bugs in SQL server with abnormal input. OPTION(MAXDOP 1) will sidestep them.

EDIT: Old. My testing was done largely on SQL 2005. Most of these seem to not exist anymore, but every once in awhile we question the assumption when SQL 2014 does something dumb and we go back to the old way and it works. We never managed to demonstrate that it wasn't just a bad plan generation on more recent cases though since SQL server can be relied on to get the old way right in newer versions. Since all cases were IO bound queries MAXDOP 1 doesn't hurt.

You can always look at how wide your font is and take the average character pixel size. Then just multiply that by the number of characters you want. It's a bit tacky but it works as a quick fix.

There are a couple of ways to solve this. The least hackiest and almost what you want:

$client = new SoapClient(
    null,
    array(
        'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
        'uri' => 'http://example.com/wsdl',
        'trace' => 1,
        'use' => SOAP_LITERAL,
    )
);
$params = new \SoapVar("<Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer>", XSD_ANYXML);
$result = $client->Echo($params);

This gets you the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com/wsdl">
    <SOAP-ENV:Body>
        <ns1:Echo>
            <Acquirer>
                <Id>MyId</Id>
                <UserId>MyUserId</UserId>
                <Password>MyPassword</Password>
            </Acquirer>
        </ns1:Echo>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

That is almost exactly what you want, except for the namespace on the method name. I don't know if this is a problem. If so, you can hack it even further. You could put the <Echo> tag in the XML string by hand and have the SoapClient not set the method by adding 'style' => SOAP_DOCUMENT, to the options array like this:

$client = new SoapClient(
    null,
    array(
        'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
        'uri' => 'http://example.com/wsdl',
        'trace' => 1,
        'use' => SOAP_LITERAL,
        'style' => SOAP_DOCUMENT,
    )
);
$params = new \SoapVar("<Echo><Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer></Echo>", XSD_ANYXML);
$result = $client->MethodNameIsIgnored($params);

This results in the following request XML:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
        <Echo>
            <Acquirer>
                <Id>MyId</Id>
                <UserId>MyUserId</UserId>
                <Password>MyPassword</Password>
            </Acquirer>
        </Echo>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Finally, if you want to play around with SoapVar and SoapParam objects, you can find a good reference in this comment in the PHP manual: http://www.php.net/manual/en/soapvar.soapvar.php#104065. If you get that to work, please let me know, I failed miserably.

I had the same issue and the following fixed my issue:

1. Set the registry: npm config set registry "http://registry.npmjs.org/"
2. Removed the entry in hosts file (using Windows 7) => C:\Windows\System32\drivers\etc\hosts

You cannot directly change a form's validity. If all the descendant inputs are valid, the form is valid, if not, then it is not.

What you should do is to set the validity of the input element. Like so;

addItem.capabilities.$setValidity("youAreFat", false);

Now the input (and so the form) is invalid. You can also see which error causes invalidation.

addItem.capabilities.errors.youAreFat == true;

To install a Python package you've downloaded, you extract the archive and run the setup.py script inside:

python setup.py install

To me, this has always felt odd. It would be more natural to point a package manager at the download, as one would do in Ruby and Nodejs, eg. gem install rails-4.1.1.gem

A package manager is more comfortable too, because it's familiar and reliable. On the other hand, each setup.py is novel, because it's specific to the package. It demands faith in convention "I trust this setup.py takes the same commands as others I have used in the past". That's a regrettable tax on mental willpower.

I'm not saying the setup.py workflow is less secure than a package manager (I understand Pip just runs the setup.py inside), but certainly I feel it's awkard and jarring. There's a harmony to commands all being to the same package manager application. You might even grow fond it.

Use INDIRECT()

=SUM(INDIRECT(<start cell here> & ":" & <end cell here>))

Boxing isn't really something that you use - it is something the runtime uses so that you can handle reference and value types in the same way when necessary. For example, if you used an ArrayList to hold a list of integers, the integers got boxed to fit in the object-type slots in the ArrayList.

Using generic collections now, this pretty much goes away. If you create a List<int>, there is no boxing done - the List<int> can hold the integers directly.

My take:

public static class SocketExtensions
{
    /// <summary>
    /// Connects the specified socket.
    /// </summary>
    /// <param name="socket">The socket.</param>
    /// <param name="endpoint">The IP endpoint.</param>
    /// <param name="timeout">The timeout.</param>
    public static void Connect(this Socket socket, EndPoint endpoint, TimeSpan timeout)
    {
        var result = socket.BeginConnect(endpoint, null, null);

        bool success = result.AsyncWaitHandle.WaitOne(timeout, true);
        if (success)
        {
            socket.EndConnect(result);
        }
        else
        {
            socket.Close();
            throw new SocketException(10060); // Connection timed out.
        }
    }
}

Assuming you're running on a Windows machine...

1. Hit the F12 key
2. Select the Scripts, or Sources, tab in the developer tools
3. Click the little folder icon in the top level
4. Select your JavaScript file
5. Add a breakpoint by clicking on the line number on the left (adds a little blue marker)
6. Execute your JavaScript

Then during execution debugging you can do a handful of stepping motions...

• F8 Continue: Will continue until the next breakpoint
• F10 Step over: Steps over next function call (won't enter the library)
• F11 Step into: Steps into the next function call (will enter the library)
• Shift + F11 Step out: Steps out of the current function

Update

After reading your updated post; to debug your code I would recommend temporarily using the jQuery Development Source Code. Although this doesn't directly solve your problem, it will allow you to debug more easily. For what you're trying to achieve I believe you'll need to step-in to the library, so hopefully the production code should help you decipher what's happening.

The simplest code to align the iframe element:

Non-validating URI-reference Parser

For reference purposes, here's the IETF Spec: (TXT | HTML). In particular, Appendix B. Parsing a URI Reference with a Regular Expression demonstrates how to parse a valid regex. This is described as,

for an example of a non-validating URI-reference parser that will take any given string and extract the URI components.

Here's the regex they provide:

 ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?

As someone else said, it's probably best to leave this to a lib/framework you're already using.

The code pasted by Rivers is great. Thanks a lot! I'm new here and can't comment, I'd just want to answer to the question from javiervd (How would you set the screen_name and count with this approach?), as I've lost a lot of time to figure it out.

You need to add the parameters both to the URL and to the signature creating process. Creating a signature is the article that helped me. Here is my code:

$oauth = array(
           'screen_name' => 'DwightHoward',
           'count' => 2,
           'oauth_consumer_key' => $consumer_key,
           'oauth_nonce' => time(),
           'oauth_signature_method' => 'HMAC-SHA1',
           'oauth_token' => $oauth_access_token,
           'oauth_timestamp' => time(),
           'oauth_version' => '1.0'
         );

$options = array(
             CURLOPT_HTTPHEADER => $header,
             //CURLOPT_POSTFIELDS => $postfields,
             CURLOPT_HEADER => false,
             CURLOPT_URL => $url . '?screen_name=DwightHoward&count=2',
             CURLOPT_RETURNTRANSFER => true, CURLOPT_SSL_VERIFYPEER => false
           );

You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.

Also, remove the onclick="alert()" from your submit. This is the cause for your first undefined message.

<?php
  $posted = false;
  if( $_POST ) {
    $posted = true;

    // Database stuff here...
    // $result = mysql_query( ... )
    $result = $_POST['name'] == "danny"; // Dummy result
  }
?>

<html>
  <head></head>
  <body>

  <?php
    if( $posted ) {
      if( $result ) 
        echo "<script type='text/javascript'>alert('submitted successfully!')</script>";
      else
        echo "<script type='text/javascript'>alert('failed!')</script>";
    }
  ?>
    <form action="" method="post">
      Name:<input type="text" id="name" name="name"/>
      <input type="submit" value="submit" name="submit"/>
    </form>
  </body>
</html>

I realise that there are many answers, but I found a solution that may be helpful to some. I ran into the same problem, I am running oracle sql develop on my local computer and I have a bunch of users. I happen to remember the password for one of my users and I used it to reset the password of other users.

Steps:

1. connect to a database using a valid user and password, in my case all my users expired except "system" and I remember that password

2. find the "Other_users" node within the tree as the image below displays

3.within the "Other_users" tree find your users that you would like to reset password of and right click the note and select "Edit Users"

4.fill out the new password in edit user dialog and click "Apply". Make sure that you have unchecked "Password expired (user must change next login)".

And that worked for me, It is not as good as other solution because you need to be able to login to at least one account but it does work.

The other answers are all good. For Xilinx FPGA designs, it is best not to use global reset lines, and use initial blocks for reset conditions for most logic. Here is the white paper from Ken Chapman (Xilinx FPGA guru)

http://japan.xilinx.com/support/documentation/white_papers/wp272.pdf

do this:

$("tr.item").each(function(i, tr) {
    var value = $("span.value", tr).text();
    var quantity = $("input.quantity", tr).val();
});

string = string.filter ({!" ".contains($0) })

That's the way I use it:

global.ts

export var server: string = 'http://localhost:4200/';
export var var2: number = 2;
export var var3: string = 'var3';

to use it just import like that:

import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Rx';
import * as glob from '../shared/global'; //<== HERE

@Injectable()
export class AuthService {
    private AuhtorizationServer = glob.server
}

EDITED: Droped "_" prefixed as recommended.

JSON doesn't allow breaking lines for readability.

Your best bet is to use an IDE that will line-wrap for you.

You need to put the font files in assets folder (may be a fonts sub-folder within assets) and refer to it in the styles:

@font-face {
  font-family: lato;
  src: url(assets/font/Lato.otf) format("opentype");
}

Once done, you can apply this font any where like:

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  font-family: 'lato', 'arial', sans-serif;
}

You can put the @font-face definition in your global styles.css or styles.scss and you would be able to refer to the font anywhere - even in your component specific CSS/SCSS. styles.css or styles.scss is already defined in angular-cli.json. Or, if you want you can create a separate CSS/SCSS file and declare it in angular-cli.json along with the styles.css or styles.scss like:

"styles": [
  "styles.css",
  "fonts.css"
],

Check INDEX Function:

=INDEX('C:\path\[file.xlsm]Sheet1'!A10:B20;1;1)

Most likely you have incorrect compiler options imported from Maven here:

Also check project and module bytecode (target) version settings outlined on the screenshot.

Other places where the source language level is configured:

• Project Structure | Project

• Project Structure | Modules (check every module) | Sources

Maven default language level is 1.5 (5.0), you will see this version as the Module language level on the screenshot above.

This can be changed using maven-compiler-plugin configuration inside pom.xml:

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

or

<project>
  [...]
  <properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
  </properties>
  [...]
</project>

IntelliJ IDEA will respect this setting after you Reimport the Maven project in the Maven Projects tool window:

If url helper is loaded, use

current_url();

will be better

You also can lead your initial string, which you are going to check for pattern matching, to lower case. And using in your pattern lower case symbols respectively .

If you are on a OS X, this probably has nothing to do with the sed command. On the OSX version of sed, the -i option expects an extension argument so your command is actually parsed as the extension argument and the file path is interpreted as the command code.

Try adding the -e argument explicitly and giving '' as argument to -i:

find ./ -type f -exec sed -i '' -e "s/192.168.20.1/new.domain.com/" {} \;

See this.

To toggle a checkbox or you can use

element.checked = !element.checked;

so you could use

if (attribute == elementName)
{
    arrChecks[i].checked = !arrChecks[i].checked;
} else {
    arrChecks[i].checked = false;
}

Removing child association cascading

So, you need to remove the @CascadeType.ALL from the @ManyToOne association. Child entities should not cascade to parent associations. Only parent entities should cascade to child entities.

@ManyToOne(fetch= FetchType.LAZY)

Notice that I set the fetch attribute to FetchType.LAZY because eager fetching is very bad for performance.

Setting both sides of the association

Whenever you have a bidirectional association, you need to synchronize both sides using addChild and removeChild methods in the parent entity:

public void addTransaction(Transaction transaction) {
    transcations.add(transaction);
    transaction.setAccount(this);
}

public void removeTransaction(Transaction transaction) {
    transcations.remove(transaction);
    transaction.setAccount(null);
}

CASCADE will also delete the corresponding field connected with it.

Yes,that is called short-circuiting.

Please take a look at this wikipedia page on short-circuiting

Use csv.writer:

import csv

with open('thefile.csv', 'rb') as f:
  data = list(csv.reader(f))

import collections
counter = collections.defaultdict(int)
for row in data:
    counter[row[0]] += 1


writer = csv.writer(open("/path/to/my/csv/file", 'w'))
for row in data:
    if counter[row[0]] >= 4:
        writer.writerow(row)

Of course, out-of-source builds are the go-to method for Unix Makefiles, but if you're using another generator such as Eclipse CDT, it prefers you to build in-source. In which case, you'll need to purge the CMake files manually. Try this:

find . -name 'CMakeCache.txt' -o -name '*.cmake' -o -name 'Makefile' -o -name 'CMakeFiles' -exec rm -rf {} +

Or if you've enabled globstar with shopt -s globstar, try this less disgusting approach instead:

rm -rf **/CMakeCache.txt **/*.cmake **/Makefile **/CMakeFiles

Perhaps you don't have to include the single quotes:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/&fileName=1.doc"

Update: Reading curl's manual, you could actually separate both fields with two --data:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/" --data "fileName=1.doc"

You could also try --data-binary:

curl --request POST 'http://localhost/Service' --data-binary "path=/xyz/pqr/test/" --data-binary "fileName=1.doc"

And --data-urlencode:

curl --request POST 'http://localhost/Service' --data-urlencode "path=/xyz/pqr/test/" --data-urlencode "fileName=1.doc"

You can't.

"The Samsung Emulator has the same functionality as the Generic Android Emulator, but varies with the size and appearance of the device."

The problem with Samsung is that they don't use a generic android image, they have custom apps and they react in custom ways and do weird things you wouldn't expect and when you're trying to fix bugs that's what you want. You cannot get that. You need access to a physical device to get the right ecosystem to hunt down the bugs and map out which intents work and how they work on that device. And sometimes there are errors that only occur on Samsung devices because some of the core rendering code is different as well. I've had errors where all Android devices except Samsung would work flawlessly but the scheme itself could not work on Samsung and had to be scrapped. The only thing Samsung allows is skinning and that won't properly note the changes in the rendering pipeline or how the samsung ecosystem deals with intents.

You can make the device look similar, that's worthless. I don't care what it looks like, I care whether this bug still affects that particular model or whether the tweak to the intents I made rectified the issue and I can't learn that from a pretty picture as the border to the same device.

Usually this happens if something is wrong with the byte array.

File.WriteAllBytes("filename.PDF", Byte[]);

This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.

Asynchronous implementation of this is also available.

public static System.Threading.Tasks.Task WriteAllBytesAsync 
(string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = null);

Nurik's answer was very helpful, but I couldn't get it to work until I found this. In short, if you're using the compatibility library (eg SupportFragmentManager instead of FragmentManager), the syntax of the XML animation files will be different.

You can use eval() for this purpose

>>> url = "'http address'"
>>> eval(url)
'http address'

while eval() poses risk , i think in this context it is safe.

Python 3:

pip3 install -r requirements.txt

Python 2:

pip install -r requirements.txt

To get all the dependencies for the virtual environment or for the whole system:

pip freeze

To push all the dependencies to the requirements.txt (Linux):

pip freeze > requirements.txt

You are pointing to the source directory. You can run a build by running ant from that same directory, then add '\output\build' to the end of the installation directory path.

"no suitable driver" usually means that the syntax for the connection URL is incorrect.

Lock is a questionable idea in JS which is intended to be threadless and not needing concurrency protection. You're looking to combine calls on deferred execution. The pattern I follow for this is the use of callbacks. Something like this:

var functionLock = false;
var functionCallbacks = [];
var lockingFunction = function (callback) {
    if (functionLock) {
        functionCallbacks.push(callback);
    } else {
        $.longRunning(function(response) {
             while(functionCallbacks.length){
                 var thisCallback = functionCallbacks.pop();
                 thisCallback(response);
             }
        });
    }
}

You can also implement this using DOM event listeners or a pubsub solution.

I found that we can use color selector for tint attr:

mImageView.setEnabled(true);

activity_main.xml:

<ImageView
    android:id="@+id/image_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_arrowup"
    android:tint="@color/section_arrowup_color" />

section_arrowup_color.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@android:color/white" android:state_enabled="true"/>
    <item android:color="@android:color/black" android:state_enabled="false"/>
    <item android:color="@android:color/white"/>
</selector>

IP Address

You can get network interfaces with NetworkInterface.getNetworkInterfaces(), then the IP addresses off the NetworkInterface objects returned with .getInetAddresses(), then the string representation of those addresses with .getHostAddress().

Port

If you make a @Configuration class which implements ApplicationListener<EmbeddedServletContainerInitializedEvent>, you can override onApplicationEvent to get the port number once it's set.

@Override
public void onApplicationEvent(EmbeddedServletContainerInitializedEvent event) {
    int port = event.getEmbeddedServletContainer().getPort();
}

Port numbers are defined by convention. HTTP servers generally listen on port 80, ssh servers listen on 22. But there are no requirements that they do.

Simplest solution? Don't let the browser cache at all. Append the current time (in ms) as a query.

(You are still in beta, so you could make a reasonable case for not optimizing for performance. But YMMV here.)

Subversion supports a command named "Cleanup"; it is used to release the locks on a project

For web developers, this seems to be the equivalent to data-..

Instead of command: docker run

You should use:

docker start **CONTAINER ID**

because the container is already exist

Creating a virtual environment for Jupyter Notebooks

A minimal Python install is

sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip

Then you can create and use the environment

/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate

You can make a kernel for Jupyter with

ipython3 kernel install --user --name=test

You can indeed place create a block of statements to execute after a conditional. But you have the syntax wrong. The parentheses must be used exactly as shown:

if <statement> (
    do something
) else (
    do something else
)

However, I do not believe that there is any built-in syntax for else-if statements. You will unfortunately need to create nested blocks of if statements to handle that.

Secondly, that %GPMANAGER_FOUND% == true test looks mighty suspicious to me. I don't know what the environment variable is set to or how you're setting it, but I very much doubt that the code you've shown will produce the result you're looking for.

The following sample code works fine for me:

@echo off

if ERRORLEVEL == 0 (
    echo GP Manager is up
    goto Continue7
)
echo GP Manager is down
:Continue7

Please note a few specific details about my sample code:

• The space added between the end of the conditional statement, and the opening parenthesis.
• I am setting @echo off to keep from seeing all of the statements printed to the console as they execute, and instead just see the output of those that specifically begin with echo.
• I'm using the built-in ERRORLEVEL variable just as a test. Read more here

Summary,

Code solution: Here

Configuration solutions: Here

With the help of Mike Chaliy, I found some solutions on how to do this through code. Because this issue is going to affect pretty much all projects we deploy to a live environment I held out for a purely configuration solution. I eventually found one which details how to do it in .net 3.0 and .net 3.5.

Taken from the site, below is an example of how to alter your applications web config:

<system.serviceModel>
    <serviceHostingEnvironment>
        <baseAddressPrefixFilters>
            <add prefix="net.tcp://payroll.myorg.com:8000"/>
            <add prefix="http://shipping.myorg.com:9000"/>
        </baseAddressPrefixFilters>
    </serviceHostingEnvironment>
</system.serviceModel>

In the above example, net.tcp://payroll.myorg.com:8000 and http://shipping.myorg.com:9000 are the only base addresses, for their respective schemes, which will be allowed to be passed through. The baseAddressPrefixFilter does not support any wildcards .

The baseAddresses supplied by IIS may have addresses bound to other schemes not present in baseAddressPrefixFilter list. These addresses will not be filtered out.

Dns solution (untested): I think that if you created a new dns entry specific to your web application, added a new web site, and gave it a single host header matching the dns entry, you would mitigate this issue altogether, and would not have to write custom code or add prefixes to your web.config file.

What does it mean?

That means that each iterator you obtain from a ConcurrentHashMap is designed to be used by a single thread and should not be passed around. This includes the syntactic sugar that the for-each loop provides.

What happens if I try to iterate the map with two threads at the same time?

It will work as expected if each of the threads uses it's own iterator.

What happens if I put or remove a value from the map while iterating it?

It is guaranteed that things will not break if you do this (that's part of what the "concurrent" in ConcurrentHashMap means). However, there is no guarantee that one thread will see the changes to the map that the other thread performs (without obtaining a new iterator from the map). The iterator is guaranteed to reflect the state of the map at the time of it's creation. Futher changes may be reflected in the iterator, but they do not have to be.

In conclusion, a statement like

for (Object o : someConcurrentHashMap.entrySet()) {
    // ...
}

will be fine (or at least safe) almost every time you see it.

This looks like a problem with line endings in your code. If you're going to be using all these other scientific packages, you may as well use Pandas for the CSV reading part, which is both more robust and more useful than just the csv module:

import pandas
colnames = ['year', 'name', 'city', 'latitude', 'longitude']
data = pandas.read_csv('test.csv', names=colnames)

If you want your lists as in the question, you can now do:

names = data.name.tolist()
latitude = data.latitude.tolist()
longitude = data.longitude.tolist()

var str = "How are you doing today?";

var res = str.split(" ");

Here the variable "res" is kind of array.

You can also take this explicity by declaring it as

var res[]= str.split(" ");

Now you can access the individual words of the array. Suppose you want to access the third element of the array you can use it by indexing array elements.

var FirstElement= res[0];

Now the variable FirstElement contains the value 'How'

An quick solution would be to create a new local directory for example c:\git_2014, In this directory rightklick and choose Git Clone

For Visual Studio Code editor with Windows Sub-system for Linux, i.e, WSL mode:

sudo npm install nodemon -g

for global use of nodemon.

PDFClown might help, but I would not recommend it for a big or heavy use application.

Since Python 3.2, there are built-in functions for byte manipulation: https://docs.python.org/3.4/library/stdtypes.html#int.to_bytes.

By combining to_bytes and from_bytes, you get

def twos(val_str, bytes):
    import sys
    val = int(val_str, 2)
    b = val.to_bytes(bytes, byteorder=sys.byteorder, signed=False)                                                          
    return int.from_bytes(b, byteorder=sys.byteorder, signed=True)

Check:

twos('11111111', 1)  # gives -1
twos('01111111', 1)  # gives 127

For older versions of Python, travc's answer is good but it does not work for negative values if one would like to work with integers instead of strings. A twos' complement function for which f(f(val)) == val is true for each val is:

def twos_complement(val, nbits):
    """Compute the 2's complement of int value val"""
    if val < 0:
        val = (1 << nbits) + val
    else:
        if (val & (1 << (nbits - 1))) != 0:
            # If sign bit is set.
            # compute negative value.
            val = val - (1 << nbits)
    return val

By default, Sublime Text set 'UTF8 without BOM', but that wasn't specified.

The only specicified things is 'UTF8 with BOM'.

Hope this help :)

We can write a bash script like below

truncate_tables_in_mysql() {
    type mysql >/dev/null 2>&1 && echo "MySQL present." || sudo apt-get install -y mysql-client
    
    tables=$(mysql -h 127.0.0.1 -P $MYSQL_PORT -u $MYSQL_USER  -p$MYSQL_PASSWORD -e "USE $BACKEND_DATABASE;    
SHOW TABLES;")
    tables_list=($tables)
    
    query_string="USE $BACKEND_DATABASE; SET FOREIGN_KEY_CHECKS = 0;"
    for table in "${tables_list[@]:1}"
    do
        query_string="$query_string TRUNCATE TABLE \`$table\`; "
    done
    query_string="$query_string SET FOREIGN_KEY_CHECKS = 1;"
    
    mysql -h 127.0.0.1 -P $MYSQL_PORT -u $MYSQL_USER -p$MYSQL_PASSWORD -e "$query_string"
}

You can replace env variables with your MySQL details. Using one command you can truncate all the tables in a DB.

The error happens because of you are trying to map a numeric vector to data in geom_errorbar: GVW[1:64,3]. ggplot only works with data.frame.

In general, you shouldn't subset inside ggplot calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame and you will be able to plot everything in one call.

Here with a dplyr solution to summarise the data and compute the standard error beforehand.

library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
    summarise(mean = mean(value),se = sd(value) / sqrt(n()))

ggplot(d, aes(x = variable, y = mean, fill = Genotype)) + 
  geom_bar(position = position_dodge(), stat = "identity", 
      colour="black", size=.3) +
  geom_errorbar(aes(ymin = mean - se, ymax = mean + se), 
      size=.3, width=.2, position=position_dodge(.9)) +
  xlab("Time") +
  ylab("Weight [g]") +
  scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"), 
      labels = c("Knock-out", "Wild type")) +
  ggtitle("Effect of genotype on weight-gain") +
  scale_y_continuous(breaks = 0:20*4) +
  theme_bw()

set autoHideMenuBar to true while creating the browserWindow

mainWindow = new BrowserWindow({
    autoHideMenuBar: true,
    width: 1200,
    height: 800
})

sys.tables

Contains all tables. so exec this query to get all tables with details.

SELECT * FROM sys.tables

or simply select Name from sys.tables to get the name of all tables.

SELECT Name From sys.tables

If you use maven, you can add this in pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>
            <configuration>
                <argLine>-Dspring.profiles.active=test</argLine>
            </configuration>
        </plugin>
        ...

Then, maven should run your integration tests (*IT.java) using this arugument, and also IntelliJ will start with this profile activated - so you can then specify all properties inside

application-test.yml

and you should not need "-default" properties.

UPDATE some_table 
   SET this_column=x, that_column=y 
   WHERE something LIKE 'them'

You can read it from the input stream:

public ActionResult ManagePhotos(ManagePhotos model)
{
    if (ModelState.IsValid)
    {
        byte[] image = new byte[model.File.ContentLength];
        model.File.InputStream.Read(image, 0, image.Length); 

        // TODO: Do something with the byte array here
    }
    ...
}

And if you intend to directly save the file to the disk you could use the model.File.SaveAs method. You might find the following blog post useful.

Try placing $PATH at the end.

export PATH=/usr/local/git/bin:/usr/local/bin:$PATH

"As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use

npm cache verify

instead."

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

http://www.coderanch.com/t/515475/JDBC/databases/sql-insert-statement-giving-sqlcode

For windows, there are automatic installer packages available at this site

It includes most of the python packages.

But the best way for it is of course using pip.

It means maven is not able to download artifacts from repository. Following steps will help you:

1. Go to repository browser and check if artifact exist.
2. Check settings.xml to see if proper respository is specified.
3. Check proxy settings.

Hope this will help somebody to develop custom checkbox component with custom styles. This solution can use with forms too.

Usage

Outside forms

<app-checkbox [label]="'Example'" [isChecked]="true"></app-checkbox>

Inside forms

<app-checkbox [label]="'Type 0'" formControlName="Type1"></app-checkbox>

    function limit_word($start,$limit,$text){
            $limit=$limit-1;
            $stripped_string =strip_tags($text);
            $string_array =explode(' ',$stripped_string);
            if(count($string_array)>$limit){
            $truncated_array = array_splice($string_array,$start,$limit);
            $text=implode(' ',$truncated_array).'...';
            return($text);
            }
            else{return($text);}
    }

This was how I solved it:

mysql> DROP DATABASE mydatabase;
ERROR 1010 (HY000): Error dropping database (can't rmdir '.\mydatabase', errno: 13)
mysql> 

I went to delete this directory: C:\...\UniServerZ\core\mysql\data\mydatabase.

mysql> DROP DATABASE mydatabase;
ERROR 1008 (HY000): Can't drop database 'mydatabase'; database doesn't exist

As others have said, you can achieve this through an IFormatProvider. But bear in mind that currency formatting goes well beyond the currency symbol. For example a correctly-formatted price in the US may be "$ 12.50" but in France this would be written "12,50 $" (the decimal point is different as is the position of the currency symbol). You don't want to lose this culture-appropriate formatting just for the sake of changing the currency symbol. And the good news is that you don't have to, as this code demonstrates:

var cultureInfo = Thread.CurrentThread.CurrentCulture;   // You can also hardcode the culture, e.g. var cultureInfo = new CultureInfo("fr-FR"), but then you lose culture-specific formatting such as decimal point (. or ,) or the position of the currency symbol (before or after)
var numberFormatInfo = (NumberFormatInfo)cultureInfo.NumberFormat.Clone();
numberFormatInfo.CurrencySymbol = "€"; // Replace with "$" or "£" or whatever you need

var price = 12.3m;
var formattedPrice = price.ToString("C", numberFormatInfo); // Output: "€ 12.30" if the CurrentCulture is "en-US", "12,30 €" if the CurrentCulture is "fr-FR".

If you have a date object:

let date = new Date()_x000D_
let result = date.toISOString().split`T`[0]_x000D_
_x000D_
console.log(result)

or

let date = new Date()_x000D_
let result = date.toISOString().slice(0, 10)_x000D_
_x000D_
console.log(result)

I just spent some serious time figuring some things out with React and scrolling events / positions - so for those still looking, here's what I found:

The viewport height can be found by using window.innerHeight or by using document.documentElement.clientHeight. (Current viewport height)

The height of the entire document (body) can be found using window.document.body.offsetHeight.

If you're attempting to find the height of the document and know when you've hit the bottom - here's what I came up with:

if (window.pageYOffset >= this.myRefII.current.clientHeight && Math.round((document.documentElement.scrollTop + window.innerHeight)) < document.documentElement.scrollHeight - 72) {
        this.setState({
            trueOrNot: true
        });
      } else {
        this.setState({
            trueOrNot: false
        });
      }
    }

(My navbar was 72px in fixed position, thus the -72 to get a better scroll-event trigger)

Lastly, here are a number of scroll commands to console.log(), which helped me figure out my math actively.

console.log('window inner height: ', window.innerHeight);

console.log('document Element client hieght: ', document.documentElement.clientHeight);

console.log('document Element scroll hieght: ', document.documentElement.scrollHeight);

console.log('document Element offset height: ', document.documentElement.offsetHeight);

console.log('document element scrolltop: ', document.documentElement.scrollTop);

console.log('window page Y Offset: ', window.pageYOffset);

console.log('window document body offsetheight: ', window.document.body.offsetHeight);

Whew! Hope it helps someone!

Tried everything that was suggested but finally this helped me:

sudo jupyter notebook --allow-root

In my case, it didn't start the browser by itself. So just copy the link from terminal and open it by yourself.

Update: Change folder(.local) permissions by this command:

sudo chmod -R 777 .local

New -> Batch Drawable Import -> Click on Add button -> Select image -> Select Target Resolution, Target Name, Format -> Ok

Along with the Memoize Example I found the following python packages:

• cachepy; It allows to set up ttl and\or the number of calls for cached functions; Also, one can use encrypted file-based cache...
• percache

As einpoklum mentioned in their answer, since C++17 you can also use structured binding declarations. I want to extend on that by providing a full solution for iterating over a map of maps in a comfortable way:

int main() {
    std::map<std::string, std::map<std::string, std::string>> m {
        {"name1", {{"value1", "data1"}, {"value2", "data2"}}},
        {"name2", {{"value1", "data1"}, {"value2", "data2"}}},
        {"name3", {{"value1", "data1"}, {"value2", "data2"}}}
    };

    for (const auto& [k1, v1] : m)
        for (const auto& [k2, v2] : v1)
            std::cout << "m[" << k1 << "][" << k2 << "]=" << v2 << std::endl;

    return 0;
}

Note 1: For filling the map, I used an initializer list (which is a C++11 feature). This can sometimes be handy to keep fixed initializations compact.

Note 2: If you want to modify the map m within the loops, you have to remove the const keywords.

Code on Coliru

You should try this way. It will definitely work.

(function() {

var app = angular.module('myApp', []);

 app.controller('myController', ['$scope', function($scope) {

    $scope.myText = "Object Push inside ";

    $scope.arrayText = [

        ];

    $scope.addText = function() {
        $scope.arrayText.push(this.myText);
    }

 }]);

})();

In your case $scope.arrayText is an object. You should initialize as a array.

I am using succinct MVVM-friendly solution that hasn't been mentioned yet. First, I name the PasswordBox in XAML:

<PasswordBox x:Name="Password" />

Then I add a single method call into view constructor:

public LoginWindow()
{
    InitializeComponent();
    ExposeControl<LoginViewModel>.Expose(this, view => view.Password,
        (model, box) => model.SetPasswordBox(box));
}

And that's it. View model will receive notification when it is attached to a view via DataContext and another notification when it is detached. The contents of this notification are configurable via the lambdas, but usually it's just a setter or method call on the view model, passing the problematic control as a parameter.

It can be made MVVM-friendly very easily by having the view expose interface instead of child controls.

The above code relies on helper class published on my blog.

Small update on Marc we will have additional " , " at the end. i used stuff function to remove extra semicolon .

       SELECT STUFF((  SELECT ',' + ModuleValue AS ModuleValue
                           FROM ModuleValue WHERE ModuleID=@ModuleID
                      FOR XML PATH('') 
                     ), 1, 1, '' )

Best programmatically Understanding.

when syntax is {}then this is JsonObject

when syntax is [] then this is JsonArray

A JSONObject is a JSON-like object that can be represented as an element in the JSONArray. JSONArray can contain a (or many) JSONObject

Hope this will helpful to you !

"Is there also a way to pass coords directly to google maps to display?"

I have found that if I pass a URL containing the coords to the browser, Android asks if I want the browser or the Maps app, as long as the user hasn't chosen the browser as the default. See my answer here for more info on the formating of the URL.

I guess if you used an intent to launch the Maps App with the coords, that would work also.

It's working in my case blinking text at 1s interval.

.blink_me {
  color:#e91e63;

  font-weight:bold;
  padding:0 20px 0  0;
  animation: blinker 1s linear infinite;
}

@keyframes blinker {
  50% { opacity: 0.4; }
}

Try something like this (use this.url to get the url):

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

Install rvm, which manages the ruby versions:

to install rvm use the following command.

 \curl -sSL https://get.rvm.io | bash -s stable
 source ~/.bash_profile
 rvm install ruby-2.1.4

Check ruby versions installed and in use:

rvm list
rvm use --default ruby-2.1.4

Alternatively to information_schema it is possible to use pg_tables:

select * from pg_tables where schemaname='public';

You can also use one more way. Three20 library offers a method through which we can construct a styled textView. You can get the library here: http://github.com/facebook/three20/

The class TTStyledTextLabel has a method called textFromXHTML: I guess this would serve the purpose. But it would be possible in readonly mode. I don't think it will allow to write or edit HTML content.

There is also a question which can help you regarding this: HTML String content for UILabel and TextView

I hope its helpful.

I found myself requiring this functionality often enough that I packaged it into a library called std-pour. It should let you execute a command and view the output in real time. To install simply:

npm install std-pour

Then it's simple enough to execute a command and see the output in realtime:

const { pour } = require('std-pour');
pour('ping', ['8.8.8.8', '-c', '4']).then(code => console.log(`Error Code: ${code}`));

It's promised based so you can chain multiple commands. It's even function signature-compatible with child_process.spawn so it should be a drop in replacement anywhere you're using it.

A rather roundabout way, just for completeness:

Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.

I lost 16 minutes of my life with this issue, so I'll just admit to this incredibly embarrassing mistake that I was making- I'm using Butterknife and I bind the view in onCreateView in this fragment.

It took a long time to figure out why I had no layoutmanager - but obviously the views are injected so they won't actually be null, so the the recycler will never be null .. whoops!

@BindView(R.id.recycler_view)
RecyclerView recyclerView;

    @Override
public View onCreateView(......) {
    View v = ...;
    ButterKnife.bind(this, v);
    setUpRecycler()
 }

public void setUpRecycler(Data data)
   if (recyclerView == null) {
 /*very silly because this will never happen*/
       LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
       //more setup
       //...
    }
    recyclerView.setAdapter(new XAdapter(data));
}

If you are getting an issue like this trace your view and use something like uiautomatorviewer

Kindly use this one liner:

Sheets.Add(After:=Sheets(Sheets.Count)).Name = "new_sheet_name"

Just move it to /usr/local/bin folder and remove the extension

sudo mv composer.phar /usr/local/bin/composer

I have used this:

document.onkeydown = keyboardDown;
document.onkeyup = keyboardUp;
document.oncontextmenu = function(e){
 var evt = new Object({keyCode:93});
 stopEvent(e);
 keyboardUp(evt);
}
function stopEvent(event){
 if(event.preventDefault != undefined)
  event.preventDefault();
 if(event.stopPropagation != undefined)
  event.stopPropagation();
}
function keyboardDown(e){
 ...
}
function keyboardUp(e){
 ...
}

Then I catch e.keyCode property in those two last functions - if e.keyCode == 93, I know that the user either released the right mouse button or pressed/released the Context Menu key.

Hope it helps.

Through discourse it's clear that the problem lies in using VS2010 to write the query, as it uses the canonical CONCAT() function which is limited to 2 parameters. There's probably a way to change that, but I'm not aware of it.

An alternative:

SELECT '1'+'2'+'3'

This approach requires non-string values to be cast/converted to strings, as well as NULL handling via ISNULL() or COALESCE():

SELECT  ISNULL(CAST(Col1 AS VARCHAR(50)),'')
      + COALESCE(CONVERT(VARCHAR(50),Col2),'')

version 4.7.1 was slightly different : for import:

import org.antlr.v4.runtime.*;

for the main segment - note the CharStreams:

CharStream in = CharStreams.fromString("12*(5-6)");
ExpLexer lexer = new ExpLexer(in);
CommonTokenStream tokens = new CommonTokenStream(lexer);
ExpParser parser = new ExpParser(tokens);

One considerable difference is about porting Python2 to Python3. urllib2 does not exist for python3 and its methods ported to urllib. So you are using that heavily and want to migrate to Python3 in future, consider using urllib. However 2to3 tool will automatically do most of the work for you.

That data:image/png;base64 URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.

Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.

Instead of passing a variable around I do this which is self-contained at the top of any page you don't want direct access to, this should still be paired with .htaccess rules but I feel safer knowing there is a fail-safe if htaccess ever gets messes up.

<?php
// Security check: Deny direct file access; must be loaded through index
if (count(get_included_files()) == 1) {
    header("Location: index.php"); // Send to index
    die("403"); // Must include to stop PHP from continuing
}
?>

You can loop through a hash map like this

<%
ArrayList list = new ArrayList();
TreeMap itemList=new TreeMap();

Now it's possible and supported by all major browsers: https://developer.mozilla.org/en-US/docs/Web/API/File/File

var file = new File(["foo"], "foo.txt", {
  type: "text/plain",
});

It's a simple matter of setting an environment variable on your executable (NSZombieEnabled = YES), and then running/debugging your app as normal.If you message a zombie, your app will crash/break to debugger and NSLog a message for you.

For more information, check out this CocoaDev page: http://www.cocoadev.com/index.pl?NSZombieEnabled

Also, this process will become much easier with the release of 10.6 and the next versions of Xcode and Instruments. Just saying'. =)

I'm using XAMPP with Apache2.4, I had this same issue. I wanted to leave the default xampp/htdocs folder in place, be able to access it from locahost and have a Virtual Host to point to my dev area...

The full contents of my C:\xampp\apache\conf\extra\http-vhosts.conf file is below...

# Virtual Hosts
#
# Required modules: mod_log_config

# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.4/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#

##NameVirtualHost *:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ##ServerName or ##ServerAlias in any <VirtualHost> block.
#
##<VirtualHost *:80>
    ##ServerAdmin [email protected]
    ##DocumentRoot "C:/xampp/htdocs/dummy-host.example.com"
    ##ServerName dummy-host.example.com
    ##ServerAlias www.dummy-host.example.com
    ##ErrorLog "logs/dummy-host.example.com-error.log"
    ##CustomLog "logs/dummy-host.example.com-access.log" common
##</VirtualHost>

##<VirtualHost *:80>
    ##ServerAdmin [email protected]
    ##DocumentRoot "C:/xampp/htdocs/dummy-host2.example.com"
    ##ServerName dummy-host2.example.com
    ##ErrorLog "logs/dummy-host2.example.com-error.log"
    ##CustomLog "logs/dummy-host2.example.com-access.log" common
##</VirtualHost>


<VirtualHost *:80>
    DocumentRoot "C:\xampp\htdocs"
    ServerName localhost
</VirtualHost>


<VirtualHost *:80>
    DocumentRoot "C:\nick\static"
    ServerName dev.middleweek.co.uk
    <Directory "C:\nick\static">
        Allow from all
        Require all granted
    </Directory>
</VirtualHost>

I then updated my C:\windows\System32\drivers\etc\hosts file like this...

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost

127.0.0.1   dev.middleweek.co.uk
127.0.0.1       localhost

Restart your machine for good measure, open the XAMPP Control Panel and start Apache.

Now open your custom domain in your browser, in the above example, it'll be http://dev.middleweek.co.uk

Hope that helps someone!

And if you want to be able to view directory listings under your new Virtual host, then edit your VirtualHost block in C:\xampp\apache\conf\extra\http-vhosts.conf to include "Options Indexes" like this...

<VirtualHost *:80>
    DocumentRoot "C:\nick\static"
    ServerName dev.middleweek.co.uk
    <Directory "C:\nick\static">
        Allow from all
        Require all granted
        Options Indexes
    </Directory>
</VirtualHost>

And you can also set a different backup extension and where to save those backup (I prefer ~/.vimbackups on linux). I used to use "versioned" backups, via:

au BufWritePre * let &bex = '-' . strftime("%Y%m%d-%H%M%S") . '.vimbackup'

This sets a dynamic backup extension (ORIGINALFILENAME-YYYYMMDD-HHMMSS.vimbackup).

There are a few different ways to accomplish this, I'll outline my favourites.

Use a ToggleButton and apply a custom style to it. I suggest this because your required control is "like a toggle button" but just looks different from the default toggle button styling.

My preferred method is to define a graphic for the button in css:

.toggle-button {
  -fx-graphic: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png');
}

.toggle-button:selected {
  -fx-graphic: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png');
}

OR use the attached css to define a background image.

// file imagetogglebutton.css deployed in the same package as ToggleButtonImage.class
.toggle-button {
  -fx-background-image: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png');
  -fx-background-repeat: no-repeat;
  -fx-background-position: center;
}

.toggle-button:selected {
  -fx-background-image: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png');
}

I prefer the -fx-graphic specification over the -fx-background-* specifications as the rules for styling background images are tricky and setting the background does not automatically size the button to the image, whereas setting the graphic does.

And some sample code:

import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.control.ToggleButton;
import javafx.scene.layout.StackPaneBuilder;
import javafx.stage.Stage;

public class ToggleButtonImage extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final ToggleButton toggle = new ToggleButton();
    toggle.getStylesheets().add(this.getClass().getResource(
      "imagetogglebutton.css"
    ).toExternalForm());
    toggle.setMinSize(148, 148); toggle.setMaxSize(148, 148);
    stage.setScene(new Scene(
      StackPaneBuilder.create()
        .children(toggle)
        .style("-fx-padding:10; -fx-background-color: cornsilk;")
        .build()
    ));
    stage.show();
  }
}

Some advantages of doing this are:

1. You get the default toggle button behavior and don't have to re-implement it yourself by adding your own focus styling, mouse and key handlers etc.
2. If your app gets ported to different platform such as a mobile device, it will work out of the box responding to touch events rather than mouse events, etc.
3. Your styling is separated from your application logic so it is easier to restyle your application.

An alternate is to not use css and still use a ToggleButton, but set the image graphic in code:

import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.scene.*;
import javafx.scene.control.ToggleButton;
import javafx.scene.image.*;
import javafx.scene.layout.StackPaneBuilder;
import javafx.stage.Stage;

public class ToggleButtonImageViaGraphic extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final ToggleButton toggle      = new ToggleButton();
    final Image        unselected  = new Image(
      "http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png"
    );
    final Image        selected    = new Image(
      "http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png"
    );
    final ImageView    toggleImage = new ImageView();
    toggle.setGraphic(toggleImage);
    toggleImage.imageProperty().bind(Bindings
      .when(toggle.selectedProperty())
        .then(selected)
        .otherwise(unselected)
    );

    stage.setScene(new Scene(
      StackPaneBuilder.create()
        .children(toggle)
        .style("-fx-padding:10; -fx-background-color: cornsilk;")
        .build()
    ));
    stage.show();
  }
}

The code based approach has the advantage that you don't have to use css if you are unfamilar with it.

For best performance and ease of porting to unsigned applet and webstart sandboxes, bundle the images with your app and reference them by relative path urls rather than downloading them off the net.

Using the dplyr package, if your data.frame is called df1:

library(dplyr)

df1 %>%
  select(A, B, E)

This can also be written without the %>% pipe as:

select(df1, A, B, E)

<form id = "uploadForm" name = "uploadForm" enctype="multipart/form-data">
    <label for="uploadFile">Upload Your File</label>
     <input type="file" name="uploadFile" id="uploadFile">                  
</form>
<script>
    $('#uploadFile').change(function(){
        var fileName = this.files[0].name;
        var fileSize = this.files[0].size;
        var fileType = this.files[0].type;
        alert('FileName : ' + fileName + '\nFileSize : ' + fileSize + ' bytes');
    });
</script>

Note: To get the uploading file name means then use jquery val() method.

For Ex:

var fileName = $('#uploadFile').val();

I checked this above code before post, it works perfectly.!

How I do:

# Remove python2
sudo apt purge -y python2.7-minimal

# You already have Python3 but 
# don't care about the version 
sudo ln -s /usr/bin/python3 /usr/bin/python

# Same for pip
sudo apt install -y python3-pip
sudo ln -s /usr/bin/pip3 /usr/bin/pip

# Confirm the new version of Python: 3
python --version

You can do it in the following way: So you will not only format the number but you can also pass as a parameter how many decimal digits to display, you set a custom decimal and mile separator.

function format(number, decimals = 2, decimalSeparator = '.', thousandsSeparator = ',') {
    const roundedNumber = number.toFixed(decimals);
    let integerPart = '', fractionalPart = '';
    if (decimals == 0) {
        integerPart = roundedNumber;
        decimalSeparator = '';
    } else {
        let numberParts = roundedNumber.split('.');
        integerPart = numberParts[0];
        fractionalPart = numberParts[1];
    }
    integerPart = integerPart.replace(/(\d)(?=(\d{3})+(?!\d))/g, `$1${thousandsSeparator}`);
    return `${integerPart}${decimalSeparator}${fractionalPart}`;
}

Use:

let min = 1556454.0001;
let max = 15556982.9999;
console.time('number format');
for (let i = 0; i < 15000; i++) {
    let randomNumber = Math.random() * (max - min) + min;

    let formated = format(randomNumber, 4, ',', '.'); // formated number

    console.debug('number: ', randomNumber, 'formated: ', formated);
}
console.timeEnd('number format');

If you want to reset bootstrap page with button click using jQuery :

function resetForm(){
        var validator = $( "#form_ID" ).validate();
        validator.resetForm();
}

Using above code you also have change the field colour as red to normal.

If you want to reset only fielded value then :

$("#form_ID")[0].reset();

Here is my approach that you may try:

import numpy as np
import matplotlib.pyplot as plt

w=10
h=10
fig=plt.figure(figsize=(8, 8))
columns = 4
rows = 5
for i in range(1, columns*rows +1):
    img = np.random.randint(10, size=(h,w))
    fig.add_subplot(rows, columns, i)
    plt.imshow(img)
plt.show()

The resulting image:

Edit 1

Since this answer is popular beyond my expectation. And I see that a small change is needed to enable flexibility for the manipulation of the individual plots. So that I offer this new version to the original code. In essence, it provides:-

1. access to individual axes of subplots
2. possibility to plot more features on selected axes/subplot

New code:

import numpy as np
import matplotlib.pyplot as plt

w = 10
h = 10
fig = plt.figure(figsize=(9, 13))
columns = 4
rows = 5

# prep (x,y) for extra plotting
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# ax enables access to manipulate each of subplots
ax = []

for i in range(columns*rows):
    img = np.random.randint(10, size=(h,w))
    # create subplot and append to ax
    ax.append( fig.add_subplot(rows, columns, i+1) )
    ax[-1].set_title("ax:"+str(i))  # set title
    plt.imshow(img, alpha=0.25)

# do extra plots on selected axes/subplots
# note: index starts with 0
ax[2].plot(xs, 3*ys)
ax[19].plot(ys**2, xs)

plt.show()  # finally, render the plot

The resulting plot:

Edit 2

In the previous example, the code provides access to the sub-plots with single index, which is inconvenient when the figure has many rows/columns of sub-plots. Here is an alternative of it. The code below provides access to the sub-plots with [row_index][column_index], which is more suitable for manipulation of array of many sub-plots.

import matplotlib.pyplot as plt
import numpy as np

# settings
h, w = 10, 10        # for raster image
nrows, ncols = 5, 4  # array of sub-plots
figsize = [6, 8]     # figure size, inches

# prep (x,y) for extra plotting on selected sub-plots
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# create figure (fig), and array of axes (ax)
fig, ax = plt.subplots(nrows=nrows, ncols=ncols, figsize=figsize)

# plot simple raster image on each sub-plot
for i, axi in enumerate(ax.flat):
    # i runs from 0 to (nrows*ncols-1)
    # axi is equivalent with ax[rowid][colid]
    img = np.random.randint(10, size=(h,w))
    axi.imshow(img, alpha=0.25)
    # get indices of row/column
    rowid = i // ncols
    colid = i % ncols
    # write row/col indices as axes' title for identification
    axi.set_title("Row:"+str(rowid)+", Col:"+str(colid))

# one can access the axes by ax[row_id][col_id]
# do additional plotting on ax[row_id][col_id] of your choice
ax[0][2].plot(xs, 3*ys, color='red', linewidth=3)
ax[4][3].plot(ys**2, xs, color='green', linewidth=3)

plt.tight_layout(True)
plt.show()

The resulting plot:

Shorter:

$html = preg_replace("/<script.*?\/script>/s", "", $html);

When doing regex things might go wrong, so it's safer to do like this:

$html = preg_replace("/<script.*?\/script>/s", "", $html) ? : $html;

So that when the "accident" happen, we get the original $html instead of empty string.

Try using below Query:

SELECT
    GROUP,
    COUNT(*) AS Total_Count
FROM
    TABLE
GROUP BY
    GROUP
ORDER BY
    Total_Count DESC
