1. Yahoo finance API Discontinued 2017-11-06###

Discontinued as of 2017-11-06 with message

It has come to our attention that this service is being used in violation of the Yahoo Terms of Service. As such, the service is being discontinued. For all future markets and equities data research, please refer to finance.yahoo.com.

Request: http://finance.yahoo.com/d/quotes.csv?e=.csv&f=sl1d1t1&s=USDINR=X
This CSV was being used by a jQuery plugin called Curry. Curry has since (2017-08-29) moved to use fixer.io instead due to stability issues. Might be useful if you need more than just a CSV.

2. (thanks to Keyo) Yahoo Query Language lets you get a whole bunch of currencies at once in XML or JSON. The data updates by the second (whereas the European Central Bank has day old data), and stops in the weekend. Doesn't require any kind of sign up.

Exchange rate from Euro to NOK on the first of January 2016:

=INDEX(GOOGLEFINANCE("CURRENCY:EURNOK"; "close"; DATE(2016;1;1)); 2; 2)

The INDEX() function is used because GOOGLEFINANCE() function actually prints out in 4 separate cells (2x2) when you call it with these arguments, with it the result will only be one cell.

If you are like me just want to print a sequence within a lambda, without get the return value (list of None).

x = range(3)
from __future__ import print_function           # if not python 3
pra = lambda seq=x: map(print,seq) and None     # pra for 'print all'
pra()
pra('abc')

If you don't need to use JQuery, as I don't. I've had problems with the cross browser func of .click(). So I use:

eval(document.getElementById('someid').href)

Google's cppclean (links to: download, documentation) can find several categories of C++ problems, and it can now find superfluous #includes.

There's also a Clang-based tool, include-what-you-use, that can do this. include-what-you-use can even suggest forward declarations (so you don't have to #include so much) and optionally clean up your #includes for you.

Current versions of Eclipse CDT also have this functionality built in: going under the Source menu and clicking Organize Includes will alphabetize your #include's, add any headers that Eclipse thinks you're using without directly including them, and comments out any headers that it doesn't think you need. This feature isn't 100% reliable, however.

If you are getting the error

Attempt by security transparent method ‘WebMatrix.WebData.PreApplicationStartCode.Start()’ to access security critical method ‘System.Web.WebPages.Razor.WebPageRazorHost.AddGlobalImport(System.String)’ failed.

In order to fix this install this package using NuGet package manager.

Install-Package Microsoft.AspNet.WebHelpers

After that , probably you will get another error

Cannot load WebMatrix.Data version 3.0.0.0 assembly

to fix this install this package using NuGet package manager.

Install-Package Microsoft.AspNet.WebPages.Data

The [] makes no sense in the moment of making an ArrayList of Integers because I imagine you just want to add Integer values. Just use

List<Integer> list = new ArrayList<>();

to create the ArrayList and it will work.

Execute this command in the command prompt and you will be good to go

npm install -g @angular/cli@version_name

I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh let's use imshow:

import numpy as np
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
              [5, 6, 7, 8],
              [9, 10, 11, 12],
              [13, 14, 15, 16]])  # added some commas and array creation code

fig = plt.figure(figsize=(6, 3.2))

ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')

cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)
cax.patch.set_alpha(0)
cax.set_frame_on(False)
plt.colorbar(orientation='vertical')
plt.show()

Using org.json

If you have a String containing JSON format text, then you can get JSON Object by following steps:

String jsonString = "{\"phonetype\":\"N95\",\"cat\":\"WP\"}";
JSONObject jsonObj = null;
    try {
        jsonObj = new JSONObject(jsonString);
    } catch (JSONException e) {
        e.printStackTrace();
    }

Now to access the phonetype

Sysout.out.println(jsonObject.getString("phonetype"));

Below function will strip the empty spces and return the strings without quotes. If there are no quotes then it will return same string(stripped)

def removeQuote(str):
str = str.strip()
if re.search("^[\'\"].*[\'\"]$",str):
    str = str[1:-1]
    print("Removed Quotes",str)
else:
    print("Same String",str)
return str

You can't do this with jQuery ajax, but with native XMLHttpRequest.

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(){
    if (this.readyState == 4 && this.status == 200){
        //this.response is what you're looking for
        handler(this.response);
        console.log(this.response, typeof this.response);
        var img = document.getElementById('img');
        var url = window.URL || window.webkitURL;
        img.src = url.createObjectURL(this.response);
    }
}
xhr.open('GET', 'http://jsfiddle.net/img/logo.png');
xhr.responseType = 'blob';
xhr.send();      

EDIT

So revisiting this topic, it seems it is indeed possible to do this with jQuery 3

const MyNavigator = createStackNavigator({

//header:null will be removed from upcoming versions

In addition, since info locals does not display the arguments to the function you're in, use

(gdb) info args

For example:

int main(int argc, char *argv[]) {
    argc = 6*7;    //Break here.
    return 0;
}

argc and argv won't be shown by info locals. The message will be "No locals."

Reference: info locals command.

To write in the Visual Studio output window I used IVsOutputWindow and IVsOutputWindowPane. I included as members in my OutputWindow class which look like this :

public class OutputWindow : TextWriter
{
  #region Members

  private static readonly Guid mPaneGuid = new Guid("AB9F45E4-2001-4197-BAF5-4B165222AF29");
  private static IVsOutputWindow mOutputWindow = null;
  private static IVsOutputWindowPane mOutputPane = null;

  #endregion

  #region Constructor

  public OutputWindow(DTE2 aDte)
  {
    if( null == mOutputWindow )
    {
      IServiceProvider serviceProvider = 
      new ServiceProvider(aDte as Microsoft.VisualStudio.OLE.Interop.IServiceProvider);
      mOutputWindow = serviceProvider.GetService(typeof(SVsOutputWindow)) as IVsOutputWindow;
    }

    if (null == mOutputPane)
    {
      Guid generalPaneGuid = mPaneGuid;
      mOutputWindow.GetPane(ref generalPaneGuid, out IVsOutputWindowPane pane);

      if ( null == pane)
      {
        mOutputWindow.CreatePane(ref generalPaneGuid, "Your output window name", 0, 1);
        mOutputWindow.GetPane(ref generalPaneGuid, out pane);
      }
      mOutputPane = pane;
    }
  }

  #endregion

  #region Properties

  public override Encoding Encoding => System.Text.Encoding.Default;

  #endregion

  #region Public Methods

  public override void Write(string aMessage) => mOutputPane.OutputString($"{aMessage}\n");

  public override void Write(char aCharacter) => mOutputPane.OutputString(aCharacter.ToString());

  public void Show(DTE2 aDte)
  {
    mOutputPane.Activate();
    aDte.ExecuteCommand("View.Output", string.Empty);
  }

  public void Clear() => mOutputPane.Clear();

  #endregion
}

If you have a big text to write in output window you usually don't want to freeze the UI. In this purpose you can use a Dispatcher. To write something in output window using this implementation now you can simple do this:

Dispatcher mDispatcher = HwndSource.FromHwnd((IntPtr)mDte.MainWindow.HWnd).RootVisual.Dispatcher;

using (OutputWindow outputWindow = new OutputWindow(mDte))
{
  mDispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
  {
    outputWindow.Write("Write what you want here");
  }));
}

Chrome now has the ability to send messages from the website to the extension.

So in the extension background.js (content.js will not work) add something like:

chrome.runtime.onMessageExternal.addListener(
    function(request, sender, sendResponse) {
        if (request) {
            if (request.message) {
                if (request.message == "version") {
                    sendResponse({version: 1.0});
                }
            }
        }
        return true;
    });

This will then let you make a call from the website:

var hasExtension = false;

chrome.runtime.sendMessage(extensionId, { message: "version" },
    function (reply) {
        if (reply) {
            if (reply.version) {
                if (reply.version >= requiredVersion) {
                    hasExtension = true;
                }
            }
        }
        else {
          hasExtension = false;
        }
    });

You can then check the hasExtension variable. The only drawback is the call is asynchronous, so you have to work around that somehow.

Edit: As mentioned below, you'll need to add an entry to the manifest.json listing the domains that can message your addon. Eg:

"externally_connectable": {
    "matches": ["*://localhost/*", "*://your.domain.com/*"]
},

I had the same issue and realized that removing the parentheses worked. Sometimes having someone else read your code can be useful if you have been the only one working on it for some time.

E.g.

  cmd.CommandType = CommandType.Text(); 

Replace: cmd.CommandType = CommandType.Text;

I want form.data['field'] and form.field.value to always have the same value

This is feasible, because it involves decorated names and indexing -- i.e., completely different constructs from the barenames a and b that you're asking about, and for with your request is utterly impossible. Why ask for something impossible and totally different from the (possible) thing you actually want?!

Maybe you don't realize how drastically different barenames and decorated names are. When you refer to a barename a, you're getting exactly the object a was last bound to in this scope (or an exception if it wasn't bound in this scope) -- this is such a deep and fundamental aspect of Python that it can't possibly be subverted. When you refer to a decorated name x.y, you're asking an object (the object x refers to) to please supply "the y attribute" -- and in response to that request, the object can perform totally arbitrary computations (and indexing is quite similar: it also allows arbitrary computations to be performed in response).

Now, your "actual desiderata" example is mysterious because in each case two levels of indexing or attribute-getting are involved, so the subtlety you crave could be introduced in many ways. What other attributes is form.field suppose to have, for example, besides value? Without that further .value computations, possibilities would include:

class Form(object):
   ...
   def __getattr__(self, name):
       return self.data[name]

and

class Form(object):
   ...
   @property
   def data(self):
       return self.__dict__

The presence of .value suggests picking the first form, plus a kind-of-useless wrapper:

class KouWrap(object):
   def __init__(self, value):
       self.value = value

class Form(object):
   ...
   def __getattr__(self, name):
       return KouWrap(self.data[name])

If assignments such form.field.value = 23 is also supposed to set the entry in form.data, then the wrapper must become more complex indeed, and not all that useless:

class MciWrap(object):
   def __init__(self, data, k):
       self._data = data
       self._k = k
   @property
   def value(self):
       return self._data[self._k]
   @value.setter
   def value(self, v)
       self._data[self._k] = v

class Form(object):
   ...
   def __getattr__(self, name):
       return MciWrap(self.data, name)

The latter example is roughly as close as it gets, in Python, to the sense of "a pointer" as you seem to want -- but it's crucial to understand that such subtleties can ever only work with indexing and/or decorated names, never with barenames as you originally asked!

Why not try this

  na.zero <- function (x) {
        x[is.na(x)] <- 0
        return(x)
    }
    na.zero(df)

Do you want to keep your database on mobile? Use sqlite instead of mysql.

If the idea is to keep database on server and access from mobile. Use a webservice to fetch/ modify data.

It works fine. I am trying it here with functions as list objects:

    from random import shuffle

    def foo1():
        print "foo1",

    def foo2():
        print "foo2",

    def foo3():
        print "foo3",

    A=[foo1,foo2,foo3]

    for x in A:
        x()

    print "\r"

    shuffle(A)
    for y in A:
        y()

It prints out: foo1 foo2 foo3 foo2 foo3 foo1 (the foos in the last row have a random order)

This is not "auto-completion", this is automation. One common tool for these things is called Expect.

You might also get away with just piping input from yes.

This script:

import subprocess
import os
with open(os.devnull, "wb") as limbo:
        for n in xrange(1, 10):
                ip="192.168.0.{0}".format(n)
                result=subprocess.Popen(["ping", "-c", "1", "-n", "-W", "2", ip],
                        stdout=limbo, stderr=limbo).wait()
                if result:
                        print ip, "inactive"
                else:
                        print ip, "active"

will produce something like this output:

192.168.0.1 active
192.168.0.2 active
192.168.0.3 inactive
192.168.0.4 inactive
192.168.0.5 inactive
192.168.0.6 inactive
192.168.0.7 active
192.168.0.8 inactive
192.168.0.9 inactive

You can capture the output if you replace limbo with subprocess.PIPE and use communicate() on the Popen object:

p=Popen( ... )
output=p.communicate()
result=p.wait()

This way you get the return value of the command and can capture the text. Following the manual this is the preferred way to operate a subprocess if you need flexibility:

The underlying process creation and management in this module is handled by the Popen class. It offers a lot of flexibility so that developers are able to handle the less common cases not covered by the convenience functions.

A couple ways this can be done:

This will make it a square

ul
{
  list-style-type: square;
}

This will make it green

li
{
  color: #0F0;
}

This will prevent the text from being green

li p
{
  color: #000;
}

However that will require that all text within lists be in paragraphs so that the color is not overridden.

A better way is to make an image of a green square and use:

ul
{
  list-style: url(green-square.png);
}

This is an issue with your stored credentials in the system credential cache. You probably have the config variable 'credential.helper' set to either wincred or winstore and it is failing to clear it. If you start the Control Panel and launch the Credential Manager applet then look for items in the generic credentials section labelled "git:https://github.com". If you delete these, then the will be recreated next time but the credential helper utility will ask you for your new credentials.

After reading the w3.org spec. I found the sandbox property.

You can set sandbox="", which prevents the iframe from redirecting. That being said it won't redirect the iframe either. You will lose the click essentially.

Example here: http://jsfiddle.net/ppkzS/1/
Example without sandbox: http://jsfiddle.net/ppkzS/

Try this:

    echo "This doesn't do fallthrough"

    echo -n "This does "
    ;&

    echo "fall-through"
    ;;

In javascript , the Date.getTimezoneOffset() method returns the time-zone offset from UTC, in minutes, for the current locale.

var x = new Date();
var currentTimeZoneOffsetInHours = x.getTimezoneOffset() / 60;

Moment'timezone will be a useful tool. http://momentjs.com/timezone/

Convert Dates Between Timezones

var newYork    = moment.tz("2014-06-01 12:00", "America/New_York");
var losAngeles = newYork.clone().tz("America/Los_Angeles");
var london     = newYork.clone().tz("Europe/London");

newYork.format();    // 2014-06-01T12:00:00-04:00
losAngeles.format(); // 2014-06-01T09:00:00-07:00
london.format();     // 2014-06-01T17:00:00+01:00

Beside the quite obvious reason (IIS), there is another reason that is common enough for this problem. It is worth to quote this question and its answer here:

http://stackoverflow.com/questions/22994888/why-skype-using-http-or-https-ports-80-and-443 

So, if you have Skype installed in the computer, be sure to check this as well. The solution is quoted here:

To turn off and disable Skype usage of and listening on port 80 and port 443, open the Skype window, then click on Tools menu and select Options. Click on Advanced tab, and go to Connection sub-tab. Untick or uncheck the check box for Use port 80 and 443 as an alternatives for incoming connections option. Click on Save button and then restart Skype to make the change effective.

Obligatory answer in Swift : NSIndexPath(forRow:row, inSection: section)

You will notice that NSIndexPath.indexPathForRow(row, inSection: section) is not available in swift and you must use the first method to construct the indexPath.

To load data via a GET request you don't need any URLRequest (and no semicolons)

let listUrlString =  "http://bla.com?batchSize=" + String(batchSize) + "&fromIndex=" + String(fromIndex)
let myUrl = URL(string: listUrlString)!
let task = URLSession.shared.dataTask(with: myUrl) { ...

Try this:

li.setBackgroundColor(android.R.color.red); //or which ever color do you want

EDIT: Posting logcat file would also help.

I use this:

tbody{
  overflow-y: auto;
  height: 350px;
  width: 102%;
}
thead,tbody{
    display: block;
}

I define the columns width with bootstrap css col-md-xx. Without defining the columns width the auto-width of the doesn't match the . The 102% percent is because you lose some sapce with the overflow

I also saw this change on my Mac when I went from running pip to sudo pip. Adding -H to sudo causes the message to go away for me. E.g.

sudo -H pip install foo

man sudo tells me that -H causes sudo to set $HOME to the target users (root in this case).

So it appears pip is looking into $HOME/Library/Log and sudo by default isn't setting $HOME to /root/. Not surprisingly ~/Library/Log is owned by you as a user rather than root.

I suspect this is some recent change in pip. I'll run it with sudo -H for now to work around.

As @bulk said, it uses namespaces.

I recommend you to start using an IDE, it will suggest you to import all the required namespaces (\App\Post in this case).

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

All of the examples here (with the exception of rockacola's) require that the user physically click on the window to define focus. This isn't ideal, so .hover() is the better choice:

$(window).hover(function(event) {
    if (event.fromElement) {
        console.log("inactive");
    } else {
        console.log("active");
    }
});

This'll tell you when the user has their mouse on the screen, though it still won't tell you if it's in the foreground with the user's mouse elsewhere.

My requirements were:

• simple .env file without export prefixes (for compatibility with dotenv)
• supporting values in quotes: TEXT="alpha bravo charlie"
• supporting comments prefixed with # and empty lines
• universal for both mac/BSD and linux/GNU

Full working version compiled from the answers above:

  set -o allexport
  eval $(grep -v '^#' .env | sed 's/^/export /')

DesignerSerializationVisibilityAttribute is very useful. When you put a runtime property on a control or component, and you don't want the designer to serialize it, you use it like this:

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public Foo Bar {
    get { return baz; }
    set { baz = value; }
}

1. You can also achieve this using the backreference technique

   sed -i.bak 's/\(.*\)/prefix\1/' foo.txt
   

2. You can also use with awk like this

   awk '{print "prefix"$0}' foo.txt > tmp && mv tmp foo.txt
   

You can use the built-in Dir function or the FileSystemObject.

• Dir Function: VBA: Dir Function

• FileSystemObject: VBA: FileSystemObject - Files Collection

They each have their own strengths and weaknesses.

Dir Function

The Dir Function is a built-in, lightweight method to get a list of files. The benefits for using it are:

• Easy to Use
• Good performance (it's fast)
• Wildcard support

The trick is to understand the difference between calling it with or without a parameter. Here is a very simple example to demonstrate:

Public Sub ListFilesDir(ByVal sPath As String, Optional ByVal sFilter As String)

    Dim sFile As String

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file name
    sFile = Dir(sPath & sFilter)

   'call it again until there are no more files
    Do Until sFile = ""

        Debug.Print sFile

        'subsequent calls without param return next file name
        sFile = Dir

    Loop

End Sub

If you alter any of the files inside the loop, you will get unpredictable results. It is better to read all the names into an array of strings before doing any operations on the files. Here is an example which builds on the previous one. This is a Function that returns a String Array:

Public Function GetFilesDir(ByVal sPath As String, _
    Optional ByVal sFilter As String) As String()

    'dynamic array for names
    Dim aFileNames() As String
    ReDim aFileNames(0)

    Dim sFile As String
    Dim nCounter As Long

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file
    sFile = Dir(sPath & sFilter)

    'call it until there is no filename returned
    Do While sFile <> ""

        'store the file name in the array
        aFileNames(nCounter) = sFile

        'subsequent calls without param return next file
        sFile = Dir

        'make sure your array is large enough for another
        nCounter = nCounter + 1
        If nCounter > UBound(aFileNames) Then
            'preserve the values and grow by reasonable amount for performance
            ReDim Preserve aFileNames(UBound(aFileNames) + 255)
        End If

    Loop

    'truncate the array to correct size
    If nCounter < UBound(aFileNames) Then
        ReDim Preserve aFileNames(0 To nCounter - 1)
    End If

    'return the array of file names
    GetFilesDir = aFileNames()

End Function

File System Object

The File System Object is a library for IO operations which supports an object-model for manipulating files. Pros for this approach:

• Intellisense
• Robust object-model

You can add a reference to to "Windows Script Host Object Model" (or "Windows Scripting Runtime") and declare your objects like so:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As FileSystemObject
    Dim oFolder As Folder
    Dim oFile As File

    Set oFSO = New FileSystemObject
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

If you don't want intellisense you can do like so without setting a reference:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As Object
    Dim oFolder As Object
    Dim oFile As Object

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

Check with "uname -a" and/or "lsb_release -a" to see which version of Linux you are actually running on your AWS instance. The default Amazon AMI image uses YUM for its package manager.

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

In Kotlin language you can do it in this way:

val values = arrayOf(
    "cat",
    "dog",
    "chicken"
)

ArrayAdapter(
    this,
    android.R.layout.simple_spinner_item,
    values
).also {
    it.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
    spinner.adapter = it
}

By overriding Equals you're basically stating that you are the one who knows better how to compare two instances of a given type, so you're likely to be the best candidate to provide the best hash code.

This is an example of how ReSharper writes a GetHashCode() function for you:

public override int GetHashCode()
{
    unchecked
    {
        var result = 0;
        result = (result * 397) ^ m_someVar1;
        result = (result * 397) ^ m_someVar2;
        result = (result * 397) ^ m_someVar3;
        result = (result * 397) ^ m_someVar4;
        return result;
    }
}

As you can see it just tries to guess a good hash code based on all the fields in the class, but since you know your object's domain or value ranges you could still provide a better one.

You can use several methods to remove item(s) from an Array:

//1
someArray.shift(); // first element removed
//2
someArray = someArray.slice(1); // first element removed
//3
someArray.splice(0, 1); // first element removed
//4
someArray.pop(); // last element removed
//5
someArray = someArray.slice(0, a.length - 1); // last element removed
//6
someArray.length = someArray.length - 1; // last element removed

If you want to remove element at position x, use:

someArray.splice(x, 1);

Or

someArray = someArray.slice(0, x).concat(someArray.slice(-x));

Reply to the comment of @chill182: you can remove one or more elements from an array using Array.filter, or Array.splice combined with Array.findIndex (see MDN), e.g.

// non destructive filter > noJohn = John removed, but someArray will not change_x000D_
let someArray = getArray();_x000D_
let noJohn = someArray.filter( el => el.name !== "John" ); _x000D_

In Python 3, print became a function. This means that you need to include parenthesis now like mentioned below:

print("Hello World")

Maybe you could do it like this:

Don't use the model in first controller. Store data in some other shared object which could be then retrieved by second controller.

Look at this and this post. It's about the similar issue.

P.S.

You could probabbly use session scoped bean for that shared data...

To resolving this problem.I just create a new folder and put some new files.Then use these commond.

* git add .
* git commit 
* git remote add master `your address`

then it tells me to login in. To input your username and password. after that

git pull 
git push origin master

finished you have pushed your code to your github

You can't expect ObjectInputStream to automagically convert text into objects. The hexadecimal 54657374 is "Test" as text. You must be sending it directly as bytes.

For example, you can try:

//If you want to get user, you need start query in your mysql:
SELECT user(); // output your user: root@localhost
SELECT system_user(); // --

//If you want to get port your "mysql://user:pass@hostname:port/db"
SELECT @@port; //3306 is default

//If you want hostname your db, you can execute query
SELECT @@hostname;

Add 'error' callback (just like 'success') this way:

$.ajax({
   type: 'POST',
   url: 'submit1.php',
   data: $("#regist").serialize(),
   dataType: 'json',
   success: function() {
      $("#loading").append("<h2>you are here</h2>");
   },
   error: function(jqXhr, textStatus, errorMessage){
      console.log("Error: ", errorMessage);
   }
});

So, in my case I saw in console:

Error:  SyntaxError: Unexpected end of JSON input
  at parse (<anonymous>), ..., etc.

Stuff like 'raises exception' and 'halts execution' might be true for most compilers, but not for all. (BTW, are there assert statements that really throw exceptions?)

Here's an interesting, slightly different meaning of assert used by c6x and other TI compilers: upon seeing certain assert statements, these compilers use the information in that statement to perform certain optimizations. Wicked.

Example in C:

int dot_product(short *x, short *y, short z)
{
  int sum = 0
  int i;

  assert( ( (int)(x) & 0x3 ) == 0 );
  assert( ( (int)(y) & 0x3 ) == 0 );

  for( i = 0 ; i < z ; ++i )
    sum += x[ i ] * y[ i ];
  return sum;
}

This tells de compiler the arrays are aligned on 32-bits boundaries, so the compiler can generate specific instructions made for that kind of alignment.

The only way I have found to change this is directly on the code :

at the very beginning of your app you set

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

you should include the system.net class

I did this before calling a web service because we had to block tls1 too.

For others like me:

There was once an example in the SSL source in the directory demos/ssl/ with example code in C++. Now it's available only via the history: https://github.com/openssl/openssl/tree/691064c47fd6a7d11189df00a0d1b94d8051cbe0/demos/ssl

You probably will have to find a working version, I originally posted this answer at Nov 6 2015. And I had to edit the source -- not much.

Certificates: .pem in demos/certs/apps/: https://github.com/openssl/openssl/tree/master/demos/certs/apps

In the end, both do the same thing. There are some differences in code: Web Services doesn't add a Root namespace of project, but Service Reference adds service classes to the namespace of the project. The ServiceSoapClient class gets a different naming, which is not important. In working with TFS I'd rather use Service Reference because it works better with source control. Both work with SOAP protocols.

I find it better to use the Service Reference because it is new and will thus be better maintained.

For expect, .equal will compare objects rather than their data, and in your case it is two different arrays.

Use .eql in order to deeply compare values. Check out this link.
Or you could use .deep.equal in order to simulate same as .eql.
Or in your case you might want to check .members.

For asserts you can use .deepEqual, link.

yes yes, git gc is the solution, naturally,

and locally - you can just delete the local repository and clone it again,

but there is something more important here...

the seconds you wait for that huge git & externals to process are collected to long minutes in which are collected to hours of inefficient time spent,

Create a new (entirely, not just a branch) repository from scratch, including the only recent version of files, naturally you'll loose all the history,

but when in code-world it is not time to get sentimental, there is no point dragging along the entire 5 years of code every commit or diff, you can still store the old git & externals somewhere, if you get nostalgic :]

but, at some point you really have to move along :]

your team will thank you!

Starting with Spring Security version 3.2, the custom functionality that has been implemented by some of the older answers, exists out of the box in the form of the @AuthenticationPrincipal annotation that is backed by AuthenticationPrincipalArgumentResolver.

An simple example of it's use is:

@Controller
public class MyController {
   @RequestMapping("/user/current/show")
   public String show(@AuthenticationPrincipal CustomUser customUser) {
        // do something with CustomUser
       return "view";
   }
}

CustomUser needs to be assignable from authentication.getPrincipal()

Here are the corresponding Javadocs of AuthenticationPrincipal and AuthenticationPrincipalArgumentResolver

It seems all the answers assume high level languages and mainly C/C++.

But the question is tagged "assembly" and in all assemblers I know (for 8bit, 16bit, 32bit and 64bit CPUs), the definitions are much more clear:

byte  = 8 bits 
word  = 2 bytes
dword = 4 bytes = 2Words (dword means "double word")
qword = 8 bytes = 2Dwords = 4Words ("quadruple word")

If you are using an eclipse ide, download the mysql jdbc connector jar and point that jar to the build path. Project Java Build Path --> Libraries --> Add external jars. Connector can be obtained from http://dev.mysql.com/downloads/connector/j/

A BLOB can be 65535 bytes maximum. If you need more consider using a MEDIUMBLOB for 16777215 bytes or a LONGBLOB for 4294967295 bytes.

Hope, it will help you.

Deleting directly from file system is not safe. You can run the below script to delete all builds from all jobs ( recursively ).

def numberOfBuildsToKeep = 10
Jenkins.instance.getAllItems(AbstractItem.class).each {
  if( it.class.toString() != "class com.cloudbees.hudson.plugins.folder.Folder" && it.class.toString() != "class org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject") {
    println it.name
    builds = it.getBuilds()
    for(int i = numberOfBuildsToKeep; i < builds.size(); i++) {
        builds.get(i).delete()
      println "Deleted" + builds.get(i)
    }
  }
}

This works fine for me, I use it in my script

<?PHP
$big = "This is a sentence that has more than 100 characters in it, and I want to return a string of only full words that is no more than 100 characters!";
$small = some_function($big);
echo $small;

function some_function($string){
     $string = substr($string,0,100);
     $string = substr($string,0,strrpos($string," "));
     return $string;
}
?>

good luck

Since C++11 you can make use of std::all_of and ::isdigit:

#include <algorithm>
#include <cctype>
#include <iostream>
#include <string_view>

int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[])
{
    auto isInt = [](std::string_view str) -> bool {
        return std::all_of(str.cbegin(), str.cend(), ::isdigit);
    };

    for(auto &test : {"abc", "123abc", "123.0", "+123", "-123", "123"}) {
        std::cout << "Is '" << test << "' numeric? " 
            << (isInt(test) ? "true" : "false") << std::endl;
    }

    return 0;
}

I want to share an approach commented about and briefly discussed but show an actual example that I am currently using to help unit test EF-based services.

First, I would love to use the in-memory provider from EF Core, but this is about EF 6. Furthermore, for other storage systems like RavenDB, I'd also be a proponent of testing via the in-memory database provider. Again--this is specifically to help test EF-based code without a lot of ceremony.

Here are the goals I had when coming up with a pattern:

• It must be simple for other developers on the team to understand
• It must isolate the EF code at the barest possible level
• It must not involve creating weird multi-responsibility interfaces (such as a "generic" or "typical" repository pattern)
• It must be easy to configure and setup in a unit test

I agree with previous statements that EF is still an implementation detail and it's okay to feel like you need to abstract it in order to do a "pure" unit test. I also agree that ideally, I would want to ensure the EF code itself works--but this involves a sandbox database, in-memory provider, etc. My approach solves both problems--you can safely unit test EF-dependent code and create integration tests to test your EF code specifically.

The way I achieved this was through simply encapsulating EF code into dedicated Query and Command classes. The idea is simple: just wrap any EF code in a class and depend on an interface in the classes that would've originally used it. The main issue I needed to solve was to avoid adding numerous dependencies to classes and setting up a lot of code in my tests.

This is where a useful, simple library comes in: Mediatr. It allows for simple in-process messaging and it does it by decoupling "requests" from the handlers that implement the code. This has an added benefit of decoupling the "what" from the "how". For example, by encapsulating the EF code into small chunks it allows you to replace the implementations with another provider or totally different mechanism, because all you are doing is sending a request to perform an action.

Utilizing dependency injection (with or without a framework--your preference), we can easily mock the mediator and control the request/response mechanisms to enable unit testing EF code.

First, let's say we have a service that has business logic we need to test:

public class FeatureService {

  private readonly IMediator _mediator;

  public FeatureService(IMediator mediator) {
    _mediator = mediator;
  }

  public async Task ComplexBusinessLogic() {
    // retrieve relevant objects

    var results = await _mediator.Send(new GetRelevantDbObjectsQuery());
    // normally, this would have looked like...
    // var results = _myDbContext.DbObjects.Where(x => foo).ToList();

    // perform business logic
    // ...    
  }
}

Do you start to see the benefit of this approach? Not only are you explicitly encapsulating all EF-related code into descriptive classes, you are allowing extensibility by removing the implementation concern of "how" this request is handled--this class doesn't care if the relevant objects come from EF, MongoDB, or a text file.

Now for the request and handler, via MediatR:

public class GetRelevantDbObjectsQuery : IRequest<DbObject[]> {
  // no input needed for this particular request,
  // but you would simply add plain properties here if needed
}

public class GetRelevantDbObjectsEFQueryHandler : IRequestHandler<GetRelevantDbObjectsQuery, DbObject[]> {
  private readonly IDbContext _db;

  public GetRelevantDbObjectsEFQueryHandler(IDbContext db) {
    _db = db;
  }

  public DbObject[] Handle(GetRelevantDbObjectsQuery message) {
    return _db.DbObjects.Where(foo => bar).ToList();
  }
}

As you can see, the abstraction is simple and encapsulated. It's also absolutely testable because in an integration test, you could test this class individually--there are no business concerns mixed in here.

So what does a unit test of our feature service look like? It's way simple. In this case, I'm using Moq to do mocking (use whatever makes you happy):

[TestClass]
public class FeatureServiceTests {

  // mock of Mediator to handle request/responses
  private Mock<IMediator> _mediator;

  // subject under test
  private FeatureService _sut;

  [TestInitialize]
  public void Setup() {

    // set up Mediator mock
    _mediator = new Mock<IMediator>(MockBehavior.Strict);

    // inject mock as dependency
    _sut = new FeatureService(_mediator.Object);
  }

  [TestCleanup]
  public void Teardown() {

    // ensure we have called or expected all calls to Mediator
    _mediator.VerifyAll();
  }

  [TestMethod]
  public void ComplexBusinessLogic_Does_What_I_Expect() {
    var dbObjects = new List<DbObject>() {
      // set up any test objects
      new DbObject() { }
    };

    // arrange

    // setup Mediator to return our fake objects when it receives a message to perform our query
    // in practice, I find it better to create an extension method that encapsulates this setup here
    _mediator.Setup(x => x.Send(It.IsAny<GetRelevantDbObjectsQuery>(), default(CancellationToken)).ReturnsAsync(dbObjects.ToArray()).Callback(
    (GetRelevantDbObjectsQuery message, CancellationToken token) => {
       // using Moq Callback functionality, you can make assertions
       // on expected request being passed in
       Assert.IsNotNull(message);
    });

    // act
    _sut.ComplexBusinessLogic();

    // assertions
  }

}

You can see all we need is a single setup and we don't even need to configure anything extra--it's a very simple unit test. Let's be clear: This is totally possible to do without something like Mediatr (you would simply implement an interface and mock it for tests, e.g. IGetRelevantDbObjectsQuery), but in practice for a large codebase with many features and queries/commands, I love the encapsulation and innate DI support Mediatr offers.

If you're wondering how I organize these classes, it's pretty simple:

- MyProject
  - Features
    - MyFeature
      - Queries
      - Commands
      - Services
      - DependencyConfig.cs (Ninject feature modules)

Organizing by feature slices is beside the point, but this keeps all relevant/dependent code together and easily discoverable. Most importantly, I separate the Queries vs. Commands--following the Command/Query Separation principle.

This meets all my criteria: it's low-ceremony, it's easy to understand, and there are extra hidden benefits. For example, how do you handle saving changes? Now you can simplify your Db Context by using a role interface (IUnitOfWork.SaveChangesAsync()) and mock calls to the single role interface or you could encapsulate committing/rolling back inside your RequestHandlers--however you prefer to do it is up to you, as long as it's maintainable. For example, I was tempted to create a single generic request/handler where you'd just pass an EF object and it would save/update/remove it--but you have to ask what your intention is and remember that if you wanted to swap out the handler with another storage provider/implementation, you should probably create explicit commands/queries that represent what you intend to do. More often than not, a single service or feature will need something specific--don't create generic stuff before you have a need for it.

There are of course caveats to this pattern--you can go too far with a simple pub/sub mechanism. I've limited my implementation to only abstracting EF-related code, but adventurous developers could start using MediatR to go overboard and message-ize everything--something good code review practices and peer reviews should catch. That's a process issue, not an issue with MediatR, so just be cognizant of how you're using this pattern.

You wanted a concrete example of how people are unit testing/mocking EF and this is an approach that's working successfully for us on our project--and the team is super happy with how easy it is to adopt. I hope this helps! As with all things in programming, there are multiple approaches and it all depends on what you want to achieve. I value simplicity, ease of use, maintainability, and discoverability--and this solution meets all those demands.

Monkey is right, according to the link given by monkey

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.

I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting

Have a look at the git clean command.

git-clean - Remove untracked files from the working tree

Cleans the working tree by recursively removing files that are not under version control, starting from the current directory.

Normally, only files unknown to git are removed, but if the -x option is specified, ignored files are also removed. This can, for example, be useful to remove all build products.

My guess is that the directory ~/bin/sbt/bin is not in your PATH.

To execute programs or scripts that are in the current directory you need to prefix the command with ./, as in:

./sbt

This is a security feature in linux, so to prevent overriding of system commands (and other programs) by a malicious party dropping a file in your home directory (for example). Imagine a script called 'ls' that emails your /etc/passwd file to 3rd party before executing the ls command... Or one that executes 'rm -rf .'...

That said, unless you need something specific from the latest source code, you're best off doing what paradigmatic said in his post, and install it from the Typesafe repository.

This is not an easy one. I've come up with a Script solution. (I don't think this can be done using pure CSS)

the HTML stays the same as you posted, the CSS changes a little bit, JQuery code added.

Working Fiddle Tested on: IE10, IE9, IE8, FF, Chrome

BTW: if you have unique elements, why don't you use id's instead of classes? I think it gives a better selector performance.

Explanation of how it works: inner-container will span the entire space of the outer-container (so basically, he's not needed) but I left him there, so you wont need to change you DOM.

the table-header is relatively positioned, without a scroll (overflow: hidden), we will handle his scroll later.

the table-body have to span the rest of the inner-container height, so I used a script to determine what height to fix him. (it changes dynamically when you re-size the window) without a fixed height, the scroll wont appear, because the div will just grow large instead.. notice that this part can be done without script, if you fix the header height and use CSS3 (as shown in the end of the answer)

now it's just a matter of moving the header along with the body each time we scroll. this is done by a function assigned to the scroll event.

CSS (some of it was copied from your style)

*
{
    padding: 0;
    margin: 0;
}

body
{
    height: 100%;
    width: 100%;
}
table
{
    border-collapse: collapse; /* make simple 1px lines borders if border defined */
}
.outer-container
{
    background-color: #ccc;
    position: absolute;
    top:0;
    left: 0;
    right: 300px;
    bottom: 40px;
}

.inner-container
{
    height: 100%;
    overflow: hidden;
}

.table-header
{
    position: relative;
}
.table-body
{
    overflow: auto;
}

.header-cell
{
    background-color: yellow;
    text-align: left;
    height: 40px;
}
.body-cell 
{
    background-color: blue;
    text-align: left;
}
.col1, .col3, .col4, .col5
{
    width:120px;
    min-width: 120px;
}
.col2
{
    min-width: 300px;
}

JQuery

$(document).ready(function () {
    setTableBody();
    $(window).resize(setTableBody);
    $(".table-body").scroll(function ()
    {
        $(".table-header").offset({ left: -1*this.scrollLeft });
    });
});

function setTableBody()
{
    $(".table-body").height($(".inner-container").height() - $(".table-header").height());
}

If you don't care about fixing the header height (I saw that you fixed the cell's height in your CSS), some of the Script can be skiped if you use CSS3 :Shorter Fiddle (this will not work on IE8)

Note that for this particular application there's a standard library function, android.text.format.DateUtils.getRelativeTimeSpanString().

The Set statement is only used for object variables (like Range, Cell or Worksheet in Excel), while the simple equal sign '=' is used for elementary datatypes like Integer. You can find a good explanation for when to use set here.

The other problem is, that your variable g1val isn't actually declared as Integer, but has the type Variant. This is because the Dim statement doesn't work the way you would expect it, here (see example below). The variable has to be followed by its type right away, otherwise its type will default to Variant. You can only shorten your Dim statement this way:

Dim intColumn As Integer, intRow As Integer  'This creates two integers

For this reason, you will see the "Empty" instead of the expected "0" in the Watches window.

Try this example to understand the difference:

Sub Dimming()

  Dim thisBecomesVariant, thisIsAnInteger As Integer
  Dim integerOne As Integer, integerTwo As Integer

  MsgBox TypeName(thisBecomesVariant)  'Will display "Empty"
  MsgBox TypeName(thisIsAnInteger )  'Will display "Integer"
  MsgBox TypeName(integerOne )  'Will display "Integer"
  MsgBox TypeName(integerTwo )  'Will display "Integer"

  'By assigning an Integer value to a Variant it becomes Integer, too
  thisBecomesVariant = 0
  MsgBox TypeName(thisBecomesVariant)  'Will display "Integer"

End Sub

Two further notices on your code:

First remark: Instead of writing

'If g1val is bigger than the value in the current cell
If g1val > Cells(33, i).Value Then
  g1val = g1val   'Don't change g1val
Else
  g1val = Cells(33, i).Value  'Otherwise set g1val to the cell's value
End If

you could simply write

'If g1val is smaller or equal than the value in the current cell
If g1val <= Cells(33, i).Value Then
  g1val = Cells(33, i).Value  'Set g1val to the cell's value 
End If

Since you don't want to change g1val in the other case.

Second remark: I encourage you to use Option Explicit when programming, to prevent typos in your program. You will then have to declare all variables and the compiler will give you a warning if a variable is unknown.

Rather than querying the DOM for elements (which isn't very angular see "Thinking in AngularJS" if I have a jQuery background?) you should perform your DOM manipulation within your directive. The element is available to you in your link function.

So in your myDirective

return {
    link: function (scope, element, attr) {
        element.html('Hello world');
    }
}

If you must perform the query outside of the directive then it would be possible to use querySelectorAll in modern browers

angular.element(document.querySelectorAll("[my-directive]"));

however you would need to use jquery to support IE8 and backwards

angular.element($("[my-directive]"));

or write your own method as demonstrated here Get elements by attribute when querySelectorAll is not available without using libraries?

    //get main activity
    final Activity main_activity=getActivity();

    //list view click listener
    final ListView listView = (ListView) inflatedView.findViewById(R.id.listView_id);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String stringText;

            //in normal case
            stringText= ((TextView)view).getText().toString();                

            //in case if listview has separate item layout
            TextView textview=(TextView)view.findViewById(R.id.textview_id_of_listview_Item);
            stringText=textview.getText().toString();                

            //show selected
            Toast.makeText(main_activity, stringText, Toast.LENGTH_LONG).show();
        }
    });

    //populate listview

Also, It can be done with LINQ

var str = "Hello@Hello&Hello(Hello)";
var characters = str.Select(c => char.IsLetter(c) ? c : ',')).ToArray();             
var output = new string(characters);
Console.WriteLine(output);

you can use this code as template please customize it as per your requirement.

DefaultTableModel model = new DefaultTableModel();
List<String> list = new ArrayList<String>();

list.add(textField.getText());
list.add(comboBox.getSelectedItem());

model.addRow(list.toArray());

table.setModel(model);

here DefaultTableModel is used to add rows in JTable, you can get more info here.

There are two distinct uses of mipmaps:

1. For launcher icons when building density specific APKs. Some developers build separate APKs for every density, to keep the APK size down. However some launchers (shipped with some devices, or available on the Play Store) use larger icon sizes than the standard 48dp. Launchers use getDrawableForDensity and scale down if needed, rather than up, so the icons are high quality. For example on an hdpi tablet the launcher might load the xhdpi icon. By placing your launcher icon in the mipmap-xhdpi directory, it will not be stripped the way a drawable-xhdpi directory is when building an APK for hdpi devices. If you're building a single APK for all devices, then this doesn't really matter as the launcher can access the drawable resources for the desired density.

2. The actual mipmap API from 4.3. I haven't used this and am not familiar with it. It's not used by the Android Open Source Project launchers and I'm not aware of any other launcher using.

I will try to explain it in my own style, it might not be in computer terms but it gives you the general idea.

Let's take an example, say Household chores: cleaning dishes, taking out trash, mowing the lawn etc, also we have 3 people(threads) A, B, C to do them

Concurrent: The three individuals start different tasks independently i.e.,

A --> cleaning dishes
B --> taking out trash 
C --> mowing the lawn 

Here, the order of tasks are indeterministic and responses depends on the amount of work

Parallel: Here if we want to improve the throughput we can assign multiple people to the single task, for example, cleaning dishes we assign two people, A soaping the dishes and B washing the dishes which might improve the throughput.

cleaning the dishes:

A --> soaping the dishes
B --> washing the dishes

so on

Hope this gives an idea! now move on to the technical terms which are explained in the other answers ;)

I've always thought that if you declare your variables inside of your loop then you're wasting memory. If you have something like this:

for(;;) {
  Object o = new Object();
}

Then not only does the object need to be created for each iteration, but there needs to be a new reference allocated for each object. It seems that if the garbage collector is slow then you'll have a bunch of dangling references that need to be cleaned up.

However, if you have this:

Object o;
for(;;) {
  o = new Object();
}

Then you're only creating a single reference and assigning a new object to it each time. Sure, it might take a bit longer for it to go out of scope, but then there's only one dangling reference to deal with.

I suggest using wbr, so the code can be written like this:

<p>???????,???<wbr
></wbr>??;?????</p>

It won't lead space between charaters, while ­ won't stop spaces created by line breaks.

Easy approach:

CREATE TABLE T
(
    C [nvarchar](100) NOT NULL UNIQUE,
);

SET XACT_ABORT ON -- Turns on rollback if T-SQL statement raises a run-time error.
SELECT * FROM T; -- Check before.
BEGIN TRAN
    INSERT INTO T VALUES ('A');
    INSERT INTO T VALUES ('B');
    INSERT INTO T VALUES ('B');
    INSERT INTO T VALUES ('C');
COMMIT TRAN
SELECT * FROM T; -- Check after.
DELETE T;

This is most likely a NT file permissions problem. IUSR_ needs to have file system permissions to read whatever file you're requesting (like /inetpub/wwwroot/index.htm).

If you still have trouble, check the IIS logs, typically at \windows\system32\logfiles\W3SVC*.

I think this solution is less complex than the others written here:

<EditText
    android:inputType="numberDecimal"
    android:digits="0123456789," />

This way when you press the '.' in the soft keyboard nothing happens; only numbers and comma are allowed.

I think that Steven is actually right. To answer the original question, then, in order to set up a class method, simply assume that the first argument is not going to be a calling instance, and then make sure that you only call the method from the class.

(Note that this answer refers to Python 3.x. In Python 2.x you'll get a TypeError for calling the method on the class itself.)

For example:

class Dog:
    count = 0 # this is a class variable
    dogs = [] # this is a class variable

    def __init__(self, name):
        self.name = name #self.name is an instance variable
        Dog.count += 1
        Dog.dogs.append(name)

    def bark(self, n): # this is an instance method
        print("{} says: {}".format(self.name, "woof! " * n))

    def rollCall(n): #this is implicitly a class method (see comments below)
        print("There are {} dogs.".format(Dog.count))
        if n >= len(Dog.dogs) or n < 0:
            print("They are:")
            for dog in Dog.dogs:
                print("  {}".format(dog))
        else:
            print("The dog indexed at {} is {}.".format(n, Dog.dogs[n]))

fido = Dog("Fido")
fido.bark(3)
Dog.rollCall(-1)
rex = Dog("Rex")
Dog.rollCall(0)

In this code, the "rollCall" method assumes that the first argument is not an instance (as it would be if it were called by an instance instead of a class). As long as "rollCall" is called from the class rather than an instance, the code will work fine. If we try to call "rollCall" from an instance, e.g.:

rex.rollCall(-1)

however, it would cause an exception to be raised because it would send two arguments: itself and -1, and "rollCall" is only defined to accept one argument.

Incidentally, rex.rollCall() would send the correct number of arguments, but would also cause an exception to be raised because now n would be representing a Dog instance (i.e., rex) when the function expects n to be numerical.

This is where the decoration comes in: If we precede the "rollCall" method with

@staticmethod

then, by explicitly stating that the method is static, we can even call it from an instance. Now,

rex.rollCall(-1)

would work. The insertion of @staticmethod before a method definition, then, stops an instance from sending itself as an argument.

You can verify this by trying the following code with and without the @staticmethod line commented out.

class Dog:
    count = 0 # this is a class variable
    dogs = [] # this is a class variable

    def __init__(self, name):
        self.name = name #self.name is an instance variable
        Dog.count += 1
        Dog.dogs.append(name)

    def bark(self, n): # this is an instance method
        print("{} says: {}".format(self.name, "woof! " * n))

    @staticmethod
    def rollCall(n):
        print("There are {} dogs.".format(Dog.count))
        if n >= len(Dog.dogs) or n < 0:
            print("They are:")
            for dog in Dog.dogs:
                print("  {}".format(dog))
        else:
            print("The dog indexed at {} is {}.".format(n, Dog.dogs[n]))


fido = Dog("Fido")
fido.bark(3)
Dog.rollCall(-1)
rex = Dog("Rex")
Dog.rollCall(0)
rex.rollCall(-1)

I'm not sure how to erase through the command line, but it's fairly easily to do it through the Keychain Access app. Just go to Applications -> Utilties -> Keychain Access, then enter "github.com". You can either delete the invalid item or update the password from with the app.

These answers are all good if you want to follow good conventions but the OP wanted something simple, which is what I wanted too instead of dealing with GUI design patterns. If all you want to do is have a string in a basic GUI app you can update ad-hoc without anything fancy, you can just access it directly in your C# source.

Let's say you've got a really basic WPF app MainWindow XAML like this,

<Window x:Class="MyWPFApp.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
            xmlns:local="clr-namespace:MyWPFApp"
            mc:Ignorable="d"
            Title="MainWindow"
            Height="200"
            Width="400"
            Background="White" >
    <Grid>
        <TextBlock x:Name="textBlock"                   
                       Text=".."
                       HorizontalAlignment="Center"
                       VerticalAlignment="Top"
                       FontWeight="Bold"
                       FontFamily="Helvetica"
                       FontSize="16"
                       Foreground="Blue" Margin="0,10,0,0"
             />
        <Button x:Name="Find_Kilroy"
                    Content="Poke Kilroy"
                    Click="Button_Click_Poke_Kilroy"
                    HorizontalAlignment="Center"
                    VerticalAlignment="Center"
                    FontFamily="Helvetica"
                    FontWeight="Bold"
                    FontSize="14"
                    Width="280"
            />
    </Grid>
</Window>

That will look something like this:

In your MainWindow XAML's source, you could have something like this where all we're doing in changing the value directly via textBlock.Text's get/set functionality:

using System.Windows;

namespace MyWPFApp
{
    public partial class MainWindow : Window
    {
        public MainWindow() { InitializeComponent(); }

        private void Button_Click_Poke_Kilroy(object sender, RoutedEventArgs e)
        {
            textBlock.Text = "              \\|||/\r\n" +
                             "              (o o) \r\n" +
                             "----ooO- (_) -Ooo----";
        }
    }
}

Then when you trigger that click event by clicking the button, voila! Kilroy appears :)

Starting

start-dfs.sh (starts the namenode and the datanode)
start-mapred.sh (starts the jobtracker and the tasktracker)

Stopping

stop-dfs.sh
stop-mapred.sh

I was having trouble with a local DB.

I was able to solve this problem by stopping SQL server, and then starting SQL server, and then using the SSMS UI to change the DB properties to Multi_User.

The DB went into "Single User" Mode when i was attempting to restore a backup. I hadn't created a backup of the target database before attempting to restore (SQL 2017). this will get you every time.

Stop SQL Server, Start SQL Server, then run the above Scripts or use the UI.

You need to create a StringWriter, and pass that to the XmlWriter.

The string overload of the XmlWriter.Create is for a filename.

E.g.

using (var sw = new StringWriter()) {
  using (var xw = XmlWriter.Create(sw)) {
    // Build Xml with xw.


  }
  return sw.ToString();
}

This will remove the tab page, but you'll need to re-add it when you need it:

tabControl1.Controls.Remove(tabPage2);

If you are going to need it later, you might want to store it in a temporary tabpage before the remove and then re-add it when needed.

Warning! SQL Server 14 Express, SQL Server Management Studio, and SQL 2014 LocalDB are separate downloads, make sure you actually installed SQL Server and not just the Management Studio! SQL Server 14 express with LocalDB download link

Youtube video about entire process.
Writeup with pictures about installing SQL Server

How to select a local server:

When you are asked to connect to a 'database server' right when you open up SQL Server Management Studio do this:

1) Make sure you have Server Type: Database

2) Make sure you have Authentication: Windows Authentication (no username & password)

3) For the server name field look to the right and select the drop down arrow, click 'browse for more'

4) New window pops up 'Browse for Servers', make sure to pick 'Local Servers' tab and under 'Database Engine' you will have the local server you set up during installation of SQL Server 14

How do I create a local database inside of Microsoft SQL Server 2014?

1) After you have connected to a server, bring up the Object Explorer toolbar under 'View' (Should open by default)

2) Now simply right click on 'Databases' and then 'Create new Database' to be taken through the database creation tools!

Use this:

countries='Paris, France, Europe'
OIFS="$IFS"
IFS=', ' array=($countries)
IFS="$OIFS"

#${array[1]} == Paris
#${array[2]} == France
#${array[3]} == Europe

JPA doesn't support that and it would be useful if it did. Using columnDefinition is DB-specific and not acceptable in many cases. setting a default in the class is not enough when you retrieve a record having null values (which typically happens when you re-run old DBUnit tests). What I do is this:

public class MyObject
{
    int attrib = 0;

    /** Default is 0 */
    @Column ( nullable = true )
    public int getAttrib()

    /** Falls to default = 0 when null */
    public void setAttrib ( Integer attrib ) {
       this.attrib = attrib == null ? 0 : attrib;
    }
}

Java auto-boxing helps a lot in that.

I know 3 way to resolve your problem:

1. First if you have access to both domains you can allow access for all other domain using :

   header("Access-Control-Allow-Origin: *");

   or just a domain by adding code bellow to .htaccess file:

   <FilesMatch "\.(ttf|otf|eot|woff)$"> <IfModule mod_headers.c> SetEnvIf Origin "http(s)?://(www\.)?(google.com|staging.google.com|development.google.com|otherdomain.net|dev02.otherdomain.net)$" AccessControlAllowOrigin=$0 Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin </IfModule> </FilesMatch>

2. you can have ajax request to a php file in your server and handle request to another domain using this php file.

3. you can use jsonp , because it doesn't need permission. for this you can read our friend @BGerrissen answer.

Since version 1.3.0 AngularJS introduced extra filter parameter timezone, like following:

{{ date_expression | date : format : timezone}}

But in versions 1.3.x only supported timezone is UTC, which can be used as following:

{{ someDate | date: 'MMM d, y H:mm:ss' : 'UTC' }}

Since version 1.4.0-rc.0 AngularJS supports other timezones too. I was not testing all possible timezones, but here's for example how you can get date in Japan Standard Time (JSP, GMT +9):

{{ clock | date: 'MMM d, y H:mm:ss' : '+0900' }}

Here you can find documentation of AngularJS date filters.

NOTE: this is working only with Angular 1.x

Here's working example

There is one event which is default associate with any webcontrol. For example, in case of Button click event, in case of Check box CheckChangedEvent is there. So in case of AutoPostBack true these events are called by default and event handle at server side.

Please look at http://www.tldp.org/LDP/abs/html/parameter-substitution.html for examples

${parameter-default}, ${parameter:-default}

If parameter not set, use default. After the call, parameter is still not set.
Both forms are almost equivalent. The extra : makes a difference only when parameter has been declared, but is null.

unset EGGS
echo 1 ${EGGS-spam}   # 1 spam
echo 2 ${EGGS:-spam}  # 2 spam

EGGS=
echo 3 ${EGGS-spam}   # 3
echo 4 ${EGGS:-spam}  # 4 spam

EGGS=cheese
echo 5 ${EGGS-spam}   # 5 cheese
echo 6 ${EGGS:-spam}  # 6 cheese

${parameter=default}, ${parameter:=default}

If parameter not set, set parameter value to default.
Both forms nearly equivalent. The : makes a difference only when parameter has been declared and is null

# sets variable without needing to reassign
# colons suppress attempting to run the string
unset EGGS
: ${EGGS=spam}
echo 1 $EGGS     # 1 spam
unset EGGS
: ${EGGS:=spam}
echo 2 $EGGS     # 2 spam

EGGS=
: ${EGGS=spam}
echo 3 $EGGS     # 3        (set, but blank -> leaves alone)
EGGS=
: ${EGGS:=spam}
echo 4 $EGGS     # 4 spam

EGGS=cheese
: ${EGGS:=spam}
echo 5 $EGGS     # 5 cheese
EGGS=cheese
: ${EGGS=spam}
echo 6 $EGGS     # 6 cheese

${parameter+alt_value}, ${parameter:+alt_value}

If parameter set, use alt_value, else use null string. After the call, parameter value not changed.
Both forms nearly equivalent. The : makes a difference only when parameter has been declared and is null

unset EGGS
echo 1 ${EGGS+spam}  # 1
echo 2 ${EGGS:+spam} # 2

EGGS=
echo 3 ${EGGS+spam}  # 3 spam
echo 4 ${EGGS:+spam} # 4

EGGS=cheese
echo 5 ${EGGS+spam}  # 5 spam
echo 6 ${EGGS:+spam} # 6 spam

Do not use floats to store fixed-point, accuracy-required data. This example shows how to convert a float to NVARCHAR(50) properly, while also showing why it is a bad idea to use floats for precision data.

create table #f ([Column_Name] float)
insert #f select 9072351234
insert #f select 907235123400000000000

select
    cast([Column_Name] as nvarchar(50)),
    --cast([Column_Name] as int), Arithmetic overflow
    --cast([Column_Name] as bigint), Arithmetic overflow
    CAST(LTRIM(STR([Column_Name],50)) AS NVARCHAR(50))
from #f

Output

9.07235e+009    9072351234
9.07235e+020    907235123400000010000

You may notice that the 2nd output ends with '10000' even though the data we tried to store in the table ends with '00000'. It is because float datatype has a fixed number of significant figures supported, which doesn't extend that far.

Simplest Way (no additional library required)

Kotlin:

var handler = Handler()
var isAppInBackground = true

override fun onStop() {
    super.onStop()
    handler.postDelayed({ isAppInBackground = true },2000)
}
override fun onDestroy() {
    super.onDestroy()
    handler.removeCallbacksAndMessages(null)
    isAppInBackground = false
}

Java:

Handler handler = new Handler();
boolean isAppInBackground = true;

@Override
public void onStop() {
    super.onStop();
    handler.postDelayed(() -> { isAppInBackground = true; },2000);
}
@Override
public void onDestroy() {
    super.onDestroy();
    handler.removeCallbacksAndMessages(null);
    isAppInBackground = false;
}

I was getting the above mentioned error message when I tried to push my current branch foobar:

git checkout foobar
git push origin foo

It turns out I had two local branches tracking the same remote branch:

foo -> origin/foo (some old branch)
foobar -> origin/foo (my current working branch)

It worked for me to push my current branch by using:

git push origin foobar:foo

... and to cleanup with git branch -d

It happens because of not very straight forward Servlet specification. If you are working with a native HttpServletRequest implementation you cannot get both the URL encode body and the parameters. Spring does some workarounds, which make it even more strange and nontransparent.

In such cases Spring (version 3.2.4) re-renders a body for you using data from the getParameterMap() method. It mixes GET and POST parameters and breaks the parameter order. The class, which is responsible for the chaos is ServletServerHttpRequest. Unfortunately it cannot be replaced, but the class StringHttpMessageConverter can be.

The clean solution is unfortunately not simple:

1. Replacing StringHttpMessageConverter. Copy/Overwrite the original class adjusting method readInternal().
2. Wrapping HttpServletRequest overwriting getInputStream(), getReader() and getParameter*() methods.

In the method StringHttpMessageConverter#readInternal following code must be used:

    if (inputMessage instanceof ServletServerHttpRequest) {
        ServletServerHttpRequest oo = (ServletServerHttpRequest)inputMessage;
        input = oo.getServletRequest().getInputStream();
    } else {
        input = inputMessage.getBody();
    }

Then the converter must be registered in the context.

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="true/false">
        <bean class="my-new-converter-class"/>
   </mvc:message-converters>
</mvc:annotation-driven>

The step two is described here: Http Servlet request lose params from POST body after read it once

map.setZoom(map.getZoom());

For some reasons, resize trigger did not work for me, and this one worked.

Javascript solution for your case:

console.log(unique(standardsList));

function unique(obj){
    var uniques=[];
    var stringify={};
    for(var i=0;i<obj.length;i++){
       var keys=Object.keys(obj[i]);
       keys.sort(function(a,b) {return a-b});
       var str='';
        for(var j=0;j<keys.length;j++){
           str+= JSON.stringify(keys[j]);
           str+= JSON.stringify(obj[i][keys[j]]);
        }
        if(!stringify.hasOwnProperty(str)){
            uniques.push(obj[i]);
            stringify[str]=true;
        }
    }
    return uniques;
}

Serialize both objects, then calculate Hash Code, then compare.

If you want the String composed of the last three characters, you can use substring(int):

String new_word = word.substring(word.length() - 3);

If you actually want them as a character array, you should write

char[] buffer = new char[3];
int length = word.length();
word.getChars(length - 3, length, buffer, 0);

The first two arguments to getChars denote the portion of the string you want to extract. The third argument is the array into which that portion will be put. And the last argument gives the position in the buffer where the operation starts.

If the string has less than three characters, you'll get an exception in either of the above cases, so you might want to check for that.

In my recent tests with IE8 and Firefox 3.5, it seems that both are RFC-compliant. However, they differ in their "friendliness" to the origin server. IE8 treats no-cache responses with the same semantics as max-age=0,must-revalidate. Firefox 3.5, however, seems to treat no-cache as equivalent to no-store, which sucks for performance and bandwidth usage.

Squid Cache, by default, seems to never store anything with a no-cache header, just like Firefox.

My advice would be to set public,max-age=0 for non-sensitive resources you want to have checked for freshness on every request, but still allow the performance and bandwidth benefits of caching. For per-user items with the same consideration, use private,max-age=0.

I would avoid the use of no-cache entirely, as it seems it has been bastardized by some browsers and popular caches to the functional equivalent of no-store.

Additionally, do not emulate Akamai and Limelight. While they essentially run massive caching arrays as their primary business, and should be experts, they actually have a vested interest in causing more data to be downloaded from their networks. Google might not be a good choice for emulation, either. They seem to use max-age=0 or no-cache randomly depending on the resource.

Here is a part of the response that tells you if an element is in the viewport. You may need to check if there is nothing on top of it using elementFromPoint, but it's a bit longer.

function isInViewport(element) {
  var rect = element.getBoundingClientRect();
  var windowHeight = window.innerHeight || document.documentElement.clientHeight;
  var windowWidth = window.innerWidth || document.documentElement.clientWidth;

  return rect.bottom > 0 && rect.top < windowHeight && rect.right > 0 && rect.left < windowWidth;
}

The interface ensures that you at least get the methods you are expecting; being aware of the definition of the interface ie. all abstract methods that are there to be implemented by any class inheriting the interface. so if some one makes a huge class of his own with several methods besides the ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use a reference to a subclass (in this case the interface) and assign the concrete class object to it.

additional advantage is that your code is safe from any changes to concrete class as you are subscribing to only few of the methods of concrete class and those are the ones that are going to be there as long as the concrete class inherits from the interface you are using. so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.

You can use a single quote to access the key that you set in your Java program.

If you set a Map in Java like this

Map<String,Object> hash = new HashMap<String,Object>();
hash.put("firstname", "a");
hash.put("lastname", "b");

Map<String,Object> map = new HashMap<String,Object>();
map.put("hash", hash);

Then you can access the members of 'hash' in Freemarker like this -

${hash['firstname']}
${hash['lastname']}

Output :

a
b

1. Use Concat or Union extension methods. You have to make sure that you have this direction using System.Linq; in order to use LINQ extensions methods.

2. Use the AddRange method.

There are several decisions to make:

1. The first about resource path:

   • Model the image as a resource on its own:

     • Nested in user (/user/:id/image): the relationship between the user and the image is made implicitly

     • In the root path (/image):

       • The client is held responsible for establishing the relationship between the image and the user, or;

       • If a security context is being provided with the POST request used to create an image, the server can implicitly establish a relationship between the authenticated user and the image.

   • Embed the image as part of the user

2. The second decision is about how to represent the image resource:

   • As Base 64 encoded JSON payload
   • As a multipart payload

This would be my decision track:

• I usually favor design over performance unless there is a strong case for it. It makes the system more maintainable and can be more easily understood by integrators.
• So my first thought is to go for a Base64 representation of the image resource because it lets you keep everything JSON. If you chose this option you can model the resource path as you like.
  • If the relationship between user and image is 1 to 1 I'd favor to model the image as an attribute specially if both data sets are updated at the same time. In any other case you can freely choose to model the image either as an attribute, updating the it via PUT or PATCH, or as a separate resource.
• If you choose multipart payload I'd feel compelled to model the image as a resource on is own, so that other resources, in our case, the user resource, is not impacted by the decision of using a binary representation for the image.

Then comes the question: Is there any performance impact about choosing base64 vs multipart?. We could think that exchanging data in multipart format should be more efficient. But this article shows how little do both representations differ in terms of size.

My choice Base64:

• Consistent design decision
• Negligible performance impact
• As browsers understand data URIs (base64 encoded images), there is no need to transform these if the client is a browser
• I won't cast a vote on whether to have it as an attribute or standalone resource, it depends on your problem domain (which I don't know) and your personal preference.

Thanks @Laurence Gonsalves your answer helped me a lot. your current directory will working directory of proccess so you have to give full path start from your src directory like mentioned below:

public class Run {
public static void main(String[] args) {
    File inputFile = new File("./src/main/java/input.txt");
    try {
        Scanner reader = new Scanner(inputFile);
        while (reader.hasNextLine()) {
            String data = reader.nextLine();
            System.out.println(data);
            
        }
        reader.close();
    } catch (FileNotFoundException e) {
        System.out.println("scanner error");
        e.printStackTrace();
    }
}

}

While my input.txt file is in same directory.

Simple way to sort any map in Java 8 and above

Map<String, Object> mapToSort = new HashMap<>();

List<Map.Entry<String, Object>> list = new LinkedList<>(mapToSort.entrySet());

Collections.sort(list, Comparator.comparing(o -> o.getValue().getAttribute()));

HashMap<String, Object> sortedMap = new LinkedHashMap<>();
for (Map.Entry<String, Object> map : list) {
   sortedMap.put(map.getKey(), map.getValue());
}

if you are using Java 7 and below

Map<String, Object> mapToSort = new HashMap<>();

List<Map.Entry<String, Object>> list = new LinkedList<>(mapToSort.entrySet());

Collections.sort(list, new Comparator<Map.Entry<String, Object>>() {
    @Override
    public int compare(Map.Entry<String, Object> o1, Map.Entry<String, Object> o2) {
       return o1.getValue().getAttribute().compareTo(o2.getValue().getAttribute());      
    }
});

HashMap<String, Object> sortedMap = new LinkedHashMap<>();
for (Map.Entry<String, Object> map : list) {
   sortedMap.put(map.getKey(), map.getValue());
}

While creating the object for the progressbar check the following.

This fails:

dialog = new ProgressDialog(getApplicationContext());

While adding the activities context works..

dialog = new ProgressDialog(MainActivity.this);

Open angular.json file

1.change from

"schematics": {}

to

"schematics": {
           "@schematics/angular:component": {
                   "styleext": "scss"       
             }  
  }

2. change from (at two places)

"src/styles.css"

to

"src/styles.scss"

then check and rename all .css files and update component.ts files styleUrls from .css to .scss

Your '/0' should be '\0' .. you got the slash reversed/leaning the wrong way. Your while should look like:

while (*(forward++)!='\0') 

though the != '\0' part of your expression is optional here since the loop will continue as long as it evaluates to non-zero (null is considered zero and will terminate the loop).

All "special" characters (i.e., escape sequences for non-printable characters) use a backward slash, such as tab '\t', or newline '\n', and the same for null '\0' so it's easy to remember.

Errors in the execution of aapt in task processDebugResources or processReleaseResources generally happen when one or more resources of your project are unsupported.

To find out go to the root dir of your project and run:

gradle processDebugResources --debug

This will print aapt specific error. In my case it was a file in the assets folder whose name had invalid character (LEÃO.jpg). aapt doesn't support some characters in the Latin alphabet.

But, as I explained your problem can be other than that. To know for sure you have to run processDebugResources with the option --debug.

I am using MVC4, I used following approach to redirect a custom html screen upon authorization breach.

Extend AuthorizeAttribute say CutomAuthorizer override the OnAuthorization and HandleUnauthorizedRequest

Register the CustomAuthorizer in the RegisterGlobalFilters.

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{

    filters.Add(new CustomAuthorizer());
}

upon identifying the unAuthorized access call HandleUnauthorizedRequestand redirect to the concerned controller action as shown below.

public class CustomAuthorizer : AuthorizeAttribute
{

    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        bool isAuthorized = IsAuthorized(filterContext); // check authorization
        base.OnAuthorization(filterContext);
        if (!isAuthorized && !filterContext.ActionDescriptor.ActionName.Equals("Unauthorized", StringComparison.InvariantCultureIgnoreCase)
            && !filterContext.ActionDescriptor.ControllerDescriptor.ControllerName.Equals("LogOn", StringComparison.InvariantCultureIgnoreCase))
        {

            HandleUnauthorizedRequest(filterContext);

        }
    }

    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        filterContext.Result =
       new RedirectToRouteResult(
           new RouteValueDictionary{{ "controller", "LogOn" },
                                          { "action", "Unauthorized" }

                                         });

    }
}

Note that probability is different than probability density pdf(), which some of the previous answers refer to. Probability is the chance that the variable has a specific value, whereas the probability density is the chance that the variable will be near a specific value, meaning probability over a range. So to obtain the probability you need to compute the integral of the probability density function over a given interval. As an approximation, you can simply multiply the probability density by the interval you're interested in and that will give you the actual probability.

import numpy as np
from scipy.stats import norm

data_start = -10
data_end = 10
data_points = 21
data = np.linspace(data_start, data_end, data_points)

point_of_interest = 5
mu = np.mean(data)
sigma = np.std(data)                                   
interval = (data_end - data_start) / (data_points - 1)
probability = norm.pdf(point_of_interest, loc=mu, scale=sigma) * interval

The code above will give you the probability that the variable will have an exact value of 5 in a normal distribution between -10 and 10 with 21 data points (meaning interval is 1). You can play around with a fixed interval value, depending on the results you want to achieve.

Anyone trying to do this in the ESRI GIS Table field calculator interface can do this with the Python parser:

PathToContainingFolder =

"\\".join(!FullFilePathWithFileName!.split("\\")[0:-1])

so that

\Users\me\Desktop\New folder\file.txt

becomes

\Users\me\Desktop\New folder

If you need to run request as the current user from desktop application use CredentialCache.DefaultCredentials (see on MSDN).

Your code looks fine if you need to run a request from server side code or under a different user.

Please note that you should be careful when storing passwords - consider using the SecureString version of the constructor.

andig is correct that a common reason for LayoutInflater ignoring your layout_params would be because a root was not specified. Many people think you can pass in null for root. This is acceptable for a few scenarios such as a dialog, where you don't have access to root at the time of creation. A good rule to follow, however, is that if you have root, give it to LayoutInflater.

I wrote an in-depth blog post about this that you can check out here:

https://www.bignerdranch.com/blog/understanding-androids-layoutinflater-inflate/

public class MainActivity extends AppCompatActivity implements OnClickListener  {
    Button  b1,b2;
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b1= (Button) findViewById(R.id.button);
        b2= (Button) findViewById(R.id.button2);
        b1.setOnClickListener(this);
        b2.setOnClickListener(this);
    }


    @Override
    public void onClick(View v)
    {
        if(v.getId()==R.id.button)
        {
            Intent intent=new Intent(getApplicationContext(),SignIn.class);
            startActivity(intent);
        }
        else if (v.getId()==R.id.button2)
        {
            Intent in=new Intent(getApplicationContext(),SignUpactivity.class);
            startActivity(in);
        }
    }
}

If you use Robert Harder's Base64 utility, then you can do:

InputStream is = new Base64.InputStream(cph);

Or with sun's JRE, you can do:

InputStream is = new
com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64DecoderStream(cph)

However don't rely on that class continuing to be a part of the JRE, or even continuing to do what it seems to do today. Sun say not to use it.

There are other Stack Overflow questions about Base64 decoding, such as this one.

I found the article .svnignore Example for Java.

Example: .svnignore for Ruby on Rails,

/log

/public/*.JPEG
/public/*.jpeg
/public/*.png
/public/*.gif

*.*~

And after that:

svn propset svn:ignore -F .svnignore .

Examples for .gitignore. You can use for your .svnignore

https://github.com/github/gitignore

for the sake of completeness, many solutions using sed or awk only translate a special set of characters and are hence quite large by code size and also dont translate other special characters that should be encoded.

a safe way to urlencode would be to just encode every single byte - even those that would've been allowed.

echo -ne 'some random\nbytes' | xxd -plain | tr -d '\n' | sed 's/\(..\)/%\1/g'

xxd is taking care here that the input is handled as bytes and not characters.

edit:

xxd comes with the vim-common package in Debian and I was just on a system where it was not installed and I didnt want to install it. The altornative is to use hexdump from the bsdmainutils package in Debian. According to the following graph, bsdmainutils and vim-common should have an about equal likelihood to be installed:

http://qa.debian.org/popcon-png.php?packages=vim-common%2Cbsdmainutils&show_installed=1&want_legend=1&want_ticks=1

but nevertheless here a version which uses hexdump instead of xxd and allows to avoid the tr call:

echo -ne 'some random\nbytes' | hexdump -v -e '/1 "%02x"' | sed 's/\(..\)/%\1/g'

just add them within the main bracket of the if statement like

if ((Type == 2 && PageCount == 0) || (Type == 2 && PageCount == '')) {
            PageCount= document.getElementById('<%=hfPageCount.ClientID %>').value;
}

Logically this can be rewritten in a better way too! This has exactly the same meaning

if (Type == 2 && (PageCount == 0 || PageCount == '')) {

Another good option for handling this kind of option is the pprint module, which (among other things) pretty prints long lists with one element per line:

>>> import sys
>>> import pprint
>>> pprint.pprint(sys.path)
['',
 '/usr/lib/python27.zip',
 '/usr/lib/python2.7',
 '/usr/lib/python2.7/plat-linux2',
 '/usr/lib/python2.7/lib-tk',
 '/usr/lib/python2.7/lib-old',
 '/usr/lib/python2.7/lib-dynload',
 '/usr/lib/python2.7/site-packages',

>>> 

If you want to use only FileInfo class try this

             string oldPath = @"C:\MyFolder\Myfile.xyz";
             string newpath = @"C:\NewFolder\";
             string newFileName = "new file name";
             FileInfo f1 = new FileInfo(oldPath);
           if(f1.Exists)
             {
                if(!Directory.Exists(newpath))
                {
                    Directory.CreateDirectory(newpath); 
                }
                 f1.CopyTo(string.Format("{0}{1}{2}", newpath, newFileName, f1.Extension));
             }

There is a post about this same issue on MSDN:

Getting more information about a serial port in C#

Hi Ravenb,

We can't get the information through the SerialPort type. I don't know why you need this info in your application. However, there's a solved thread with the same question as you. You can check out the code there, and see if it can help you.

If you have any further problem, please feel free to let me know.

Best regards, Bruce Zhou

The link in that post goes to this one:

How to get more info about port using System.IO.Ports.SerialPort

You can probably get this info from a WMI query. Check out this tool to help you find the right code. Why would you care though? This is just a detail for a USB emulator, normal serial ports won't have this. A serial port is simply know by "COMx", nothing more.

Seems like the order of the linking flags was not an issue in older versions of gcc. Eg gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-16) comes with Centos-6.7 happy with linker option before inputfile; but gcc with ubuntu 16.04 gcc (Ubuntu 5.3.1-14ubuntu2.1) 5.3.1 20160413 does not allow.

Its not the gcc version alone, I has got something to with the distros

There is a concurrent list implementation in java.util.concurrent. CopyOnWriteArrayList in particular.

To give you a better understanding of why this happens, I'd like to expand upon @r-samuel-klatchko's answer a bit.

When you call malloc, what is really happening is a bit more complicated than just giving you a chunk of memory to play with. Under the hood, malloc also keeps some housekeeping information about the memory it has given you (most importantly, its size), so that when you call free, it knows things like how much memory to free. This information is commonly kept right before the memory location returned to you by malloc. More exhaustive information can be found on the internet™, but the (very) basic idea is something like this:

+------+-------------------------------------------------+
+ size |                  malloc'd memory                +
+------+-------------------------------------------------+
       ^-- location in pointer returned by malloc

Building on this (and simplifying things greatly), when you call malloc, it needs to get a pointer to the next part of memory that is available. One very simple way of doing this is to look at the previous bit of memory it gave away, and move size bytes further down (or up) in memory. With this implementation, you end up with your memory looking something like this after allocating p1, p2 and p3:

+------+----------------+------+--------------------+------+----------+
+ size |                | size |                    | size |          +
+------+----------------+------+--------------------+------+----------+
       ^- p1                   ^- p2                       ^- p3

So, what is causing your error?

Well, imagine that your code erroneously writes past the amount of memory you've allocated (either because you allocated less than you needed as was your problem or because you're using the wrong boundary conditions somewhere in your code). Say your code writes so much data to p2 that it starts overwriting what is in p3's size field. When you now next call malloc, it will look at the last memory location it returned, look at its size field, move to p3 + size and then start allocating memory from there. Since your code has overwritten size, however, this memory location is no longer after the previously allocated memory.

Needless to say, this can wreck havoc! The implementors of malloc have therefore put in a number of "assertions", or checks, that try to do a bunch of sanity checking to catch this (and other issues) if they are about to happen. In your particular case, these assertions are violated, and thus malloc aborts, telling you that your code was about to do something it really shouldn't be doing.

As previously stated, this is a gross oversimplification, but it is sufficient to illustrate the point. The glibc implementation of malloc is more than 5k lines, and there have been substantial amounts of research into how to build good dynamic memory allocation mechanisms, so covering it all in a SO answer is not possible. Hopefully this has given you a bit of a view of what is really causing the problem though!

Personally, I like the version you cited, assuming you already have a list of goodvals hanging around. If not, something like:

good = filter(lambda x: is_good(x), mylist)
bad = filter(lambda x: not is_good(x), mylist)

Of course, that's really very similar to using a list comprehension like you originally did, but with a function instead of a lookup:

good = [x for x in mylist if is_good(x)]
bad  = [x for x in mylist if not is_good(x)]

In general, I find the aesthetics of list comprehensions to be very pleasing. Of course, if you don't actually need to preserve ordering and don't need duplicates, using the intersection and difference methods on sets would work well too.

A simple solution to this problem is to return from the render loop if the frame is not required to render:

const FPS = 60;
let prevTick = 0;    

function render() 
{
    requestAnimationFrame(render);

    // clamp to fixed framerate
    let now = Math.round(FPS * Date.now() / 1000);
    if (now == prevTick) return;
    prevTick = now;

    // otherwise, do your stuff ...
}

It's important to know that requestAnimationFrame depends on the users monitor refresh rate (vsync). So, relying on requestAnimationFrame for game speed for example will make it unplayable on 200Hz monitors if you're not using a separate timer mechanism in your simulation.

I believe document.documentElement.outerHTML should return that for you.

According to MDN, outerHTML is supported in Firefox 11, Chrome 0.2, Internet Explorer 4.0, Opera 7, Safari 1.3, Android, Firefox Mobile 11, IE Mobile, Opera Mobile, and Safari Mobile. outerHTML is in the DOM Parsing and Serialization specification.

The MSDN page on the outerHTML property notes that it is supported in IE 5+. Colin's answer links to the W3C quirksmode page, which offers a good comparison of cross-browser compatibility (for other DOM features too).

If you want the click handler to work for an element that gets loaded dynamically, then you set the event handler on a parent object (that does not get loaded dynamically) and give it a selector that matches your dynamic object like this:

$('#parent').on("click", "#child", function() {});

The event handler will be attached to the #parent object and anytime a click event bubbles up to it that originated on #child, it will fire your click handler. This is called delegated event handling (the event handling is delegated to a parent object).

It's done this way because you can attach the event to the #parent object even when the #child object does not exist yet, but when it later exists and gets clicked on, the click event will bubble up to the #parent object, it will see that it originated on #child and there is an event handler for a click on #child and fire your event.

Use this plugin Moment Duration Format.

Example:

moment.duration(123, "minutes").format("h:mm");

Cloning children with new props

You can use React.Children to iterate over the children, and then clone each element with new props (shallow merged) using React.cloneElement. For example:

const Child = ({ doSomething, value }) => (
  <button onClick={() => doSomething(value)}>Click Me</button>
);

class Parent extends React.Component{
  doSomething = value => {
    console.log("doSomething called by child with value:", value);
  }

  render() {
    const childrenWithProps = React.Children.map(this.props.children, child => {
      // checking isValidElement is the safe way and avoids a typescript error too
      if (React.isValidElement(child)) {
        return React.cloneElement(child, { doSomething: this.doSomething });
      }
      return child;
    });

    return <div>{childrenWithProps}</div>;
  }
}

function App() {
  return (
    <Parent>
      <Child value={1} />
      <Child value={2} />
    </Parent>
  );
}

ReactDOM.render(<App />, document.getElementById("container"));

<script src="https://unpkg.com/react@17/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom@17/umd/react-dom.production.min.js"></script>
<div id="container"></div>

Calling children as a function

Alternatively, you can pass props to children with render props. In this approach, the children (which can be children or any other prop name) is a function which can accept any arguments you want to pass and returns the children:

const Child = ({ doSomething, value }) => (
  <button onClick={() => doSomething(value)}>Click Me</button>
);

class Parent extends React.Component{
  doSomething = value => {
    console.log("doSomething called by child with value:", value);
  }

  render(){
    // note that children is called as a function and we can pass args to it
    return <div>{this.props.children(this.doSomething)}</div>
  }
};

function App(){
  return (
    <Parent>
      {doSomething => (
        <React.Fragment>
          <Child doSomething={doSomething} value={1} />
          <Child doSomething={doSomething} value={2} />
        </React.Fragment>
      )}
    </Parent>
  );
}

ReactDOM.render(<App />, document.getElementById("container"));

<script src="https://unpkg.com/react@17/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom@17/umd/react-dom.production.min.js"></script>
<div id="container"></div>

Instead of <React.Fragment> or simply <> you can also return an array if you prefer.

Generate an array of random floats or ints of the same length. Sort that array, and do corresponding swaps on your target array.

This yields a truly independent sort.

I also tried to use CURRVAL, in my case to find out if some process inserted new rows to some table with that sequence as Primary Key. My assumption was that CURRVAL would be the fastest method. But a) CurrVal does not work, it will just get the old value because you are in another Oracle session, until you do a NEXTVAL in your own session. And b) a select max(PK) from TheTable is also very fast, probably because a PK is always indexed. Or select count(*) from TheTable. I am still experimenting, but both SELECTs seem fast.

I don't mind a gap in a sequence, but in my case I was thinking of polling a lot, and I would hate the idea of very large gaps. Especially if a simple SELECT would be just as fast.

Conclusion:

• CURRVAL is pretty useless, as it does not detect NEXTVAL from another session, it only returns what you already knew from your previous NEXTVAL
• SELECT MAX(...) FROM ... is a good solution, simple and fast, assuming your sequence is linked to that table

Adding following key in registry solved my issue:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64\Performance

When I tried these steps I kept getting error:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

Then i looked at event viewer and saw this error:Unable to install counter strings because the SYSTEM\CurrentControlSet\Services\ASP.NET_64\Performance key could not be opened or accessed. The first DWORD in the Data section contains the Win32 error code.

To fix the issue i manually created following entry in registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64\Performance

and followed these steps:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

Similar to other syntax above but for learning - can you sort by column names?

sort(colnames(test[1:ncol(test)] ))

Use

Try_convert(float,[Value])

See https://raresql.com/2013/04/26/sql-server-how-to-convert-varchar-to-float/

Only ASCII or are other characters allowed too?

^\w*$

restricts (in Java) to ASCII letters/digits und underscore,

^[\pL\pN\p{Pc}]*$

also allows international characters/digits and "connecting punctuation".

Don't forget to add this piece of code from the delegate or your view will be cut off or appear behind the table in some cases, relative to the height of your view/label.

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 30;

Hey i always make methods for custom stuff that is usually not implemented in java. Here is a simple method i made for removing character from String Fast

    public static String removeChar(String str, char c){
        StringBuilder strNew=new StringBuilder(str.length());
        char charRead;
        for(int i=0;i<str.length();i++){
            charRead=str.charAt(i);
            if(charRead!=c)
                strNew.append(charRead);
        }
        return strNew.toString();
    }

For explaintion, yes there is no null character for replacing, but you can remove character like this. I know its a old question, but i am posting this answer because this code may be helpful for some persons.

You can use the express-force-https module:

npm install --save express-force-https

var express = require('express');
var secure = require('express-force-https');

var app = express();
app.use(secure);

If you want to extend the amount of time permitted for an ASP.NET script to execute then increase the Server.ScriptTimeout value. The default is 90 seconds for .NET 1.x and 110 seconds for .NET 2.0 and later.

For example:

// Increase script timeout for current page to five minutes
Server.ScriptTimeout = 300;

This value can also be configured in your web.config file in the httpRuntime configuration element:

<!-- Increase script timeout to five minutes -->
<httpRuntime executionTimeout="300" 
  ... other configuration attributes ...
/>

Please note according to the MSDN documentation:

"This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging."

If you've already done this but are finding that your session is expiring then increase the ASP.NET HttpSessionState.Timeout value:

For example:

// Increase session timeout to thirty minutes
Session.Timeout = 30;

This value can also be configured in your web.config file in the sessionState configuration element:

<configuration>
  <system.web>
    <sessionState 
      mode="InProc"
      cookieless="true"
      timeout="30" />
  </system.web>
</configuration>

If your script is taking several minutes to execute and there are many concurrent users then consider changing the page to an Asynchronous Page. This will increase the scalability of your application.

The other alternative, if you have administrator access to the server, is to consider this long running operation as a candidate for implementing as a scheduled task or a windows service.

Simply add class="img-responsive" to the video tag. I'm doing this on a current project, and it works. It doesn't need to be wrapped in anything.

<video class="img-responsive" src="file.mp4" autoplay loop/>

Although this question has already been answered, I think this approach is better : http://jsfiddle.net/kjy112/3CvaD/ extract from this question on StackOverFlow google maps - open marker infowindow given the coordinates:

Each marker gets an "infowindow" entry :

function createMarker(lat, lon, html) {
    var newmarker = new google.maps.Marker({
        position: new google.maps.LatLng(lat, lon),
        map: map,
        title: html
    });

    newmarker['infowindow'] = new google.maps.InfoWindow({
            content: html
        });

    google.maps.event.addListener(newmarker, 'mouseover', function() {
        this['infowindow'].open(map, this);
    });
}

A simple example of escaping quotes in the shell:

$ echo 'abc'\''abc'
abc'abc
$ echo "abc"\""abc"
abc"abc

It's done by finishing an already-opened one ('), placing the escaped one (\'), and then opening another one (').

Alternatively:

$ echo 'abc'"'"'abc'
abc'abc
$ echo "abc"'"'"abc"
abc"abc

It's done by finishing already opened one ('), placing a quote in another quote ("'"), and then opening another one (').

There are various ways to achieve the same. Below are some commonly used ways in spring-

1. Using PropertyPlaceholderConfigurer

2. Using PropertySource

3. Using ResourceBundleMessageSource

4. Using PropertiesFactoryBean

   and many more........................

Assuming ds.type is key in your property file.

Using PropertyPlaceholderConfigurer

Register PropertyPlaceholderConfigurer bean-

<context:property-placeholder location="classpath:path/filename.properties"/>

or

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="locations" value="classpath:path/filename.properties" ></property>
</bean>

or

@Configuration
public class SampleConfig {
 @Bean
 public static PropertySourcesPlaceholderConfigurer placeHolderConfigurer() {
  return new PropertySourcesPlaceholderConfigurer();
  //set locations as well.
 }
}

After registering PropertySourcesPlaceholderConfigurer, you can access the value-

@Value("${ds.type}")private String attr; 

Using PropertySource

In the latest spring version you don't need to register PropertyPlaceHolderConfigurer with @PropertySource, I found a good link to understand version compatibility-

@PropertySource("classpath:path/filename.properties")
@Component
public class BeanTester {
    @Autowired Environment environment; 
    public void execute() {
        String attr = this.environment.getProperty("ds.type");
    }
}

Using ResourceBundleMessageSource

Register Bean-

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
  <property name="basenames">
    <list>
      <value>classpath:path/filename.properties</value>
    </list>
  </property>
</bean>

Access Value-

((ApplicationContext)context).getMessage("ds.type", null, null);

or

@Component
public class BeanTester {
    @Autowired MessageSource messageSource; 
    public void execute() {
        String attr = this.messageSource.getMessage("ds.type", null, null);
    }
}

Using PropertiesFactoryBean

Register Bean-

<bean id="properties"
      class="org.springframework.beans.factory.config.PropertiesFactoryBean">
  <property name="locations">
    <list>
      <value>classpath:path/filename.properties</value>
    </list>
  </property>
</bean>

Wire Properties instance into your class-

@Component
public class BeanTester {
    @Autowired Properties properties; 
    public void execute() {
        String attr = properties.getProperty("ds.type");
    }
}

There is no reflection in C++. True. But if the compiler can't provide you the metadata you need, you can provide it yourself.

Let's start by making a property struct:

template<typename Class, typename T>
struct PropertyImpl {
    constexpr PropertyImpl(T Class::*aMember, const char* aName) : member{aMember}, name{aName} {}

    using Type = T;

    T Class::*member;
    const char* name;
};

template<typename Class, typename T>
constexpr auto property(T Class::*member, const char* name) {
    return PropertyImpl<Class, T>{member, name};
}

Of course, you also can have a property that takes a setter and getter instead of a pointer to member, and maybe read only properties for calculated value you'd like to serialize. If you use C++17, you can extend it further to make a property that works with lambdas.

Ok, now we have the building block of our compile-time introspection system.

Now in your class Dog, add your metadata:

struct Dog {
    std::string barkType;
    std::string color;
    int weight = 0;

    bool operator==(const Dog& rhs) const {
        return std::tie(barkType, color, weight) == std::tie(rhs.barkType, rhs.color, rhs.weight);
    }

    constexpr static auto properties = std::make_tuple(
        property(&Dog::barkType, "barkType"),
        property(&Dog::color, "color"),
        property(&Dog::weight, "weight")
    );
};

We will need to iterate on that list. To iterate on a tuple, there are many ways, but my preferred one is this:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    using unpack_t = int[];
    (void)unpack_t{(static_cast<void>(f(std::integral_constant<T, S>{})), 0)..., 0};
}

If C++17 fold expressions are available in your compiler, then for_sequence can be simplified to:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    (static_cast<void>(f(std::integral_constant<T, S>{})), ...);
}

This will call a function for each constant in the integer sequence.

If this method don't work or gives trouble to your compiler, you can always use the array expansion trick.

Now that you have the desired metadata and tools, you can iterate through the properties to unserialize:

// unserialize function
template<typename T>
T fromJson(const Json::Value& data) {
    T object;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // get the type of the property
        using Type = typename decltype(property)::Type;

        // set the value to the member
        // you can also replace `asAny` by `fromJson` to recursively serialize
        object.*(property.member) = Json::asAny<Type>(data[property.name]);
    });

    return object;
}

And for serialize:

template<typename T>
Json::Value toJson(const T& object) {
    Json::Value data;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // set the value to the member
        data[property.name] = object.*(property.member);
    });

    return data;
}

If you want recursive serialization and unserialization, you can replace asAny by fromJson.

Now you can use your functions like this:

Dog dog;

dog.color = "green";
dog.barkType = "whaf";
dog.weight = 30;

Json::Value jsonDog = toJson(dog); // produces {"color":"green", "barkType":"whaf", "weight": 30}
auto dog2 = fromJson<Dog>(jsonDog);

std::cout << std::boolalpha << (dog == dog2) << std::endl; // pass the test, both dog are equal!

Done! No need for run-time reflection, just some C++14 goodness!

This code could benefit from some improvement, and could of course work with C++11 with some ajustements.

Note that one would need to write the asAny function. It's just a function that takes a Json::Value and call the right as... function, or another fromJson.

Here's a complete, working example made from the various code snippet of this answer. Feel free to use it.

As mentionned in the comments, this code won't work with msvc. Please refer to this question if you want a compatible code: Pointer to member: works in GCC but not in VS2015

Define a class

import logging

class CustomFormatter(logging.Formatter):
    """Logging Formatter to add colors and count warning / errors"""

    grey = "\x1b[38;21m"
    yellow = "\x1b[33;21m"
    red = "\x1b[31;21m"
    bold_red = "\x1b[31;1m"
    reset = "\x1b[0m"
    format = "%(asctime)s - %(name)s - %(levelname)s - %(message)s (%(filename)s:%(lineno)d)"

    FORMATS = {
        logging.DEBUG: grey + format + reset,
        logging.INFO: grey + format + reset,
        logging.WARNING: yellow + format + reset,
        logging.ERROR: red + format + reset,
        logging.CRITICAL: bold_red + format + reset
    }

    def format(self, record):
        log_fmt = self.FORMATS.get(record.levelno)
        formatter = logging.Formatter(log_fmt)
        return formatter.format(record)

Instantiate logger

# create logger with 'spam_application'
logger = logging.getLogger("My_app")
logger.setLevel(logging.DEBUG)

# create console handler with a higher log level
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)

ch.setFormatter(CustomFormatter())

logger.addHandler(ch)

And use!

logger.debug("debug message")
logger.info("info message")
logger.warning("warning message")
logger.error("error message")
logger.critical("critical message")

The full color scheme

For windows

This solution works on Mac OS, IDE terminals. Looks like the Windows command prompt doesn't have colors at all by default. Here are instructions on how to enable them, which I haven't try https://www.howtogeek.com/322432/how-to-customize-your-command-prompts-color-scheme-with-microsofts-colortool/

I realize that this is quite and old question, but I have a 'stupid' solution to a similar problem which maybe could help someone.

I experienced the same problem with a text box which shown as selected (by the Focus method in JQuery), but did not take the cursor in.

The fact is that I had the Debugger window open to see what is happening and THAT window was stealing the focus. The solution is banally simple: just close the Debugger and everything is fine...1 hour spent in testing!

Try putting both columns in the same orderby.

orderby p.LowestPrice.HasValue descending, p.LowestPrice

Otherwise each orderby is a separate operation on the collection re-ordering it each time.

This should order the ones with a value first, "then" the order of the value.

I think we can you use verbatim tag, as in this tag we use any of the HTML tags

That's simple, if you reference them by index. If you want to hide the first column, you would:

Copy code

$('#thetable tr').find('td:nth-child(1),th:nth-child(1)').toggle();

The reason I first selected all table rows and then both td's and th's that were the n'th child is so that we wouldn't have to select the table and all table rows twice. This improves script execution speed. Keep in mind, nth-child() is 1 based, not 0.

I've solved just using this plugin: http://dotdotdot.frebsite.nl/

it automatically sets a max height to the target and adds three dots

Replace localhost with 127.0.0.1 If it doesn't work change the run configuration to support your ip address.

As it may happens that the default branch of your submodules is not master, this is how I automate the full Git submodules upgrades:

git submodule init
git submodule update
git submodule foreach 'git fetch origin; git checkout $(git rev-parse --abbrev-ref HEAD); git reset --hard origin/$(git rev-parse --abbrev-ref HEAD); git submodule update --recursive; git clean -dfx'

Create the SqlParamObject which would give you control to access methods on the parameters

:

SqlParameter param = new SqlParameter();

SET the Name for your paramter (it should b same as you would have declared a variable to hold the value in your DataBase)

: param.ParameterName = "@yourParamterName";

Clear the value holder to hold you output data

: param.Value = 0;

Set the Direction of your Choice (In your case it should be Output)

: param.Direction = System.Data.ParameterDirection.Output;

U can use eclipse. but u need to download pydev addon for that.

Jest's setupFiles is the proper way to handle this, and you need not install dotenv, nor use an .env file at all, to make it work.

jest.config.js:

module.exports = {
  setupFiles: ["<rootDir>/.jest/setEnvVars.js"]
};

.jest/setEnvVars.js:

process.env.MY_CUSTOM_TEST_ENV_VAR = 'foo'

That's it.

You could implement a JavaScript block which contains a function with your needs.

<div style="position: absolute; left: 10px; top: 40px;"> 
    <img src="logg.png" width="114" height="38" onclick="DoSomething();" />
</div>

You can use the the click function to trigger the click event on the selected element.

Example:

$( 'selector for your link' ).click ();

You can learn about various selectors in jQuery's documentation.

EDIT: like the commenters below have said; this only works on events attached with jQuery, inline or in the style of "element.onclick". It does not work with addEventListener, and it will not follow the link if no event handlers are defined. You could solve this with something like this:

var linkEl = $( 'link selector' );
if ( linkEl.attr ( 'onclick' ) === undefined ) {
    document.location = linkEl.attr ( 'href' );
} else {
    linkEl.click ();
}

Don't know about addEventListener though.

Your source files should be in a structure with a 'package' icon in the Package Explorer view (in the menu under Window > Show View > Package Explorer or press Ctrl+3 and type pack), like this:

If they are not, select the folder containing your root package (src in the image above) and select Use as Source Folder from the context menu (right click).

This a great tool for debugging & logging php: PHp Debugger & Logger

It works right out of the box with just 3 lines of code. It can send messages to the js console for ajax debugging and can replace the error handler. It also dumps information about variables like var_dump() and print_r(), but in a more readable format. Very nice tool!

You can use LINQ to achieve that too:

var exists = array.ElementAtOrDefault(index) != null;

Use 3 curly braces if you want to echo

{{{ $usersType or '' }}}

Gradle can be used for many purposes - it's a much better Swiss army knife than Ant - but it's specifically focused on multi-project builds.

First of all, Gradle is a dependency programming tool which also means it's a programming tool. With Gradle you can execute any random task in your setup and Gradle will make sure all declared dependecies are properly and timely executed. Your code can be spread across many directories in any kind of layout (tree, flat, scattered, ...).

Gradle has two distinct phases: evaluation and execution. Basically, during evaluation Gradle will look for and evaluate build scripts in the directories it is supposed to look. During execution Gradle will execute tasks which have been loaded during evaluation taking into account task inter-dependencies.

On top of these dependency programming features Gradle adds project and JAR dependency features by intergration with Apache Ivy. As you know Ivy is a much more powerful and much less opinionated dependency management tool than say Maven.

Gradle detects dependencies between projects and between projects and JARs. Gradle works with Maven repositories (download and upload) like the iBiblio one or your own repositories but also supports and other kind of repository infrastructure you might have.

In multi-project builds Gradle is both adaptable and adapts to the build's structure and architecture. You don't have to adapt your structure or architecture to your build tool as would be required with Maven.

Gradle tries very hard not to get in your way, an effort Maven almost never makes. Convention is good yet so is flexibility. Gradle gives you many more features than Maven does but most importantly in many cases Gradle will offer you a painless transition path away from Maven.

this.state.data.sort((a, b) => a.item.timeM > b.item.timeM).map(
    (item, i) => <div key={i}> {item.matchID} {item.timeM} {item.description}</div>
)

We can pass multiple parameters with var_dump like:

var_dump("array1",$array1,"array2",$array2);

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

Use mshta to prompt for admin rights:

@echo off
net session >nul 2>&1 && goto :admintasks
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute('%~nx0', '', '', 'runas', 1);close();"
exit /b
:admintasks
rem ADMIN TASKS HERE

Or, using powershell:

powershell -c Start-Process "%~nx0" -Verb runas

You're already prepending the hash sign in your showDialog() function, and you're missing single quotes in your second code snippet. You should also return false from the handler to prevent a postback from occurring. Try:

<asp:Button ID="ButtonAdd" runat="server" Text="Add"
    OnClientClick="showDialog('<%=addPerson.ClientID %>'); return false;" />

The query below will result in dd-mmm-yy format.

1. Please go to Refactor->Migrate->Migrate to Android X.

2. Please add this to your gradle.properties file:

And perform Sync.

In my case it a simple issue. I have uploaded an app in the console before so i try re uploading it after resolving some issues All i do is delete the previous APK from the Artifact Library

The right way is this:

Integer i = Integer.class.cast(obj);

The method cast() is a much safer alternative to compile-time casting.

Create a .vbs with the following code, which will open your main .vbs:

Set objShell = WScript.CreateObject("WScript.shell") 
objShell.Run "cscript.exe ""C:\QuickTestb.vbs"""

Dim i
for i = 1 To 5
     Wscript.Echo i
