This Method to get Google Username:

 public String getUsername() {
    AccountManager manager = AccountManager.get(this);
    Account[] accounts = manager.getAccountsByType("com.google");
    List<String> possibleEmails = new LinkedList<String>();

    for (Account account : accounts) {
        // TODO: Check possibleEmail against an email regex or treat
        // account.name as an email address only for certain account.type
        // values.
        possibleEmails.add(account.name);
    }

    if (!possibleEmails.isEmpty() && possibleEmails.get(0) != null) {
        String email = possibleEmails.get(0);
        String[] parts = email.split("@");
        if (parts.length > 0 && parts[0] != null)
            return parts[0];
        else
            return null;
    } else
        return null;
}

simple this method call ....

And Get Google User in Gmail id::

 accounts = AccountManager.get(this).getAccounts();
    Log.e("", "Size: " + accounts.length);
    for (Account account : accounts) {

        String possibleEmail = account.name;
        String type = account.type;

        if (type.equals("com.google")) {
            strGmail = possibleEmail;

            Log.e("", "Emails: " + strGmail);
            break;
        }
    }

After add permission in manifest;

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

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

You should do a one-time setup of creating an "App password" in Bitbucket web UI with permissions to at least read your repositories and then use it in the command line.

How-to:

1. Login to Bitbucket
2. Click on your profile image on the right (now on the bottom left)
3. Choose Bitbucket settings (now Personal settings)
4. Under Access management section look for the App passwords option (https://bitbucket.org/account/settings/app-passwords/)
5. Create an app password with permissions at least to Read under Repositories section. A password will be generated for you. Remember to save it, it will be shown only once!
6. The username will be your Google username.

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// saving an NSString
[prefs setObject:@"TextToSave" forKey:@"keyToLookupString"];

// saving an NSInteger
[prefs setInteger:42 forKey:@"integerKey"];

// saving a Double
[prefs setDouble:3.1415 forKey:@"doubleKey"];

// saving a Float
[prefs setFloat:1.2345678 forKey:@"floatKey"];

// This is suggested to synch prefs, but is not needed (I didn't put it in my tut)
[prefs synchronize];

Retrieving

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// getting an NSString
NSString *myString = [prefs stringForKey:@"keyToLookupString"];

// getting an NSInteger
NSInteger myInt = [prefs integerForKey:@"integerKey"];

// getting an Float
float myFloat = [prefs floatForKey:@"floatKey"];

You can use Manifold's @Jailbreak for direct, type-safe Java reflection:

@Jailbreak Foo foo = new Foo();
foo.callMe();

public class Foo {
    private void callMe();
}

@Jailbreak unlocks the foo local variable in the compiler for direct access to all the members in Foo's hierarchy.

Similarly you can use the jailbreak() extension method for one-off use:

foo.jailbreak().callMe();

Through the jailbreak() method you can access any member in Foo's hierarchy.

In both cases the compiler resolves the method call for you type-safely, as if a public method, while Manifold generates efficient reflection code for you under the hood.

Alternatively, if the type is not known statically, you can use Structural Typing to define an interface a type can satisfy without having to declare its implementation. This strategy maintains type-safety and avoids performance and identity issues associated with reflection and proxy code.

The modulus is a mathematical operation, sometimes described as "clock arithmetic." I find that describing it as simply a remainder is misleading and confusing because it masks the real reason it is used so much in computer science. It really is used to wrap around cycles.

Think of a clock: Suppose you look at a clock in "military" time, where the range of times goes from 0:00 - 23.59. Now if you wanted something to happen every day at midnight, you would want the current time mod 24 to be zero:

if (hour % 24 == 0):

You can think of all hours in history wrapping around a circle of 24 hours over and over and the current hour of the day is that infinitely long number mod 24. It is a much more profound concept than just a remainder, it is a mathematical way to deal with cycles and it is very important in computer science. It is also used to wrap around arrays, allowing you to increase the index and use the modulus to wrap back to the beginning after you reach the end of the array.

All you can do is to call equals() method on empty String literal and pass the object you are testing as shown below :

 String nullString = null;
 String empty = new String();
 boolean test = "".equals(empty); // true 
 System.out.println(test); 
 boolean check = "".equals(nullString); // false 
 System.out.println(check);

Here's a list of the environment variables. I think you might want CURRENT_VARIANT. See also BUILD_VARIANTS.

Code offset dynamic for dynamic page

var pos=$('#send').offset().top;
$('#loading').offset({ top : pos-220});

Dependency Injection in an ASP.NET project can be accomplished with a few lines of code. I suppose there is some advantage to using a container when you have an app that uses multiple front ends and needs unit tests.

An example with VBScript (.vbs)

Sub sety(wsh, action, typey, vary, value)
  Dim wu
  Set wu = wsh.Environment(typey)
  wui = wu.Item(vary)
  Select Case action
    Case "ls"
      WScript.Echo wui
    Case "del"
      On Error Resume Next
      wu.remove(vary)
      On Error Goto 0
    Case "set"
      wu.Item(vary) = value
    Case "add"
      If wui = "" Then
        wu.Item(vary) = value
      ElseIf InStr(UCase(";" & wui & ";"), UCase(";" & value & ";")) = 0 Then
        wu.Item(vary) = value & ";" & wui
      End If
    Case Else
      WScript.Echo "Bad action"
  End Select
End Sub

Dim wsh, args
Set wsh = WScript.CreateObject("WScript.Shell")
Set args = WScript.Arguments
Select Case WScript.Arguments.Length
  Case 3
    value = ""
  Case 4
    value = args(3)
  Case Else
    WScript.Echo "Arguments - 0: ls,del,set,add; 1: user,system, 2: variable; 3: value"
    value = "```"
End Select
If Not value = "```" Then
  ' 0: ls,del,set,add; 1: user,system, 2: variable; 3: value
  sety wsh, args(0), args(1), UCase(args(2)), value
End If

This is what I went through on Amazon/AWS EMR v5. (Adapted from the previous answers), to have Maven and Java8.

sudo wget https://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
sudo yum install -y apache-maven
sudo alternatives --config java

pick Java8

sudo alternatives --config javac

pick Java8

Now, if you run:

mvn -version

You should get:

Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T07:58:13Z)

You can get a View's coordinates using getLocationOnScreen() or getLocationInWindow()

Afterwards, x and y should be the top-left corner of the view. If your root layout is smaller than the screen (like in a Dialog), using getLocationInWindow will be relative to its container, not the entire screen.

Java Solution

int[] point = new int[2];
view.getLocationOnScreen(point); // or getLocationInWindow(point)
int x = point[0];
int y = point[1];

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post(() -> {
    // Values should no longer be 0
    int[] point = new int[2];
    view.getLocationOnScreen(point); // or getLocationInWindow(point)
    int x = point[0];
    int y = point[1];
});

~~

Kotlin Solution

val point = IntArray(2)
view.getLocationOnScreen(point) // or getLocationInWindow(point)
val (x, y) = point

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post {
    // Values should no longer be 0
    val point = IntArray(2)
    view.getLocationOnScreen(point) // or getLocationInWindow(point)
    val (x, y) = point
}

I recommend creating an extension function for handling this:

// To use, call:
val (x, y) = view.screenLocation

val View.screenLocation get(): IntArray {
    val point = IntArray(2)
    getLocationOnScreen(point)
    return point
}

And if you require reliability, also add:

view.screenLocationSafe { x, y -> Log.d("", "Use $x and $y here") }

fun View.screenLocationSafe(callback: (Int, Int) -> Unit) {
    post {
        val (x, y) = screenLocation
        callback(x, y)
    }
}

in my case (the website SSL uses ev curves) the issue with the SSL was solved by adding this option ecdhCurve: 'P-521:P-384:P-256'

request({ url, 
   agentOptions: { ecdhCurve: 'P-521:P-384:P-256', }
}, (err,res,body) => {

JFYI, maybe this will help someone

If you dont want to use $.browser, take a look at case 1, otherwise maybe case 2 and 3 can help you just to get informed because it is not recommended to use $.browser (the user agent can be spoofed using this). An alternative can be using jQuery.support that will detect feature support and not agent info.

But...

If you insist on getting browser type (just Chrome or Safari) but not using $.browser, case 1 is what you looking for...

This fits your requirement:

Case 1: (No jQuery and no $.browser, just javascript)

Live Demo: http://jsfiddle.net/oscarj24/DJ349/

var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);
var isSafari = /Safari/.test(navigator.userAgent) && /Apple Computer/.test(navigator.vendor);

if (isChrome) alert("You are using Chrome!");
if (isSafari) alert("You are using Safari!");

These cases I used in times before and worked well but they are not recommended...

Case 2: (Using jQuery and $.browser, this one is tricky)

Live Demo: http://jsfiddle.net/oscarj24/gNENk/

$(document).ready(function(){

    /* Get browser */
    $.browser.chrome = /chrome/.test(navigator.userAgent.toLowerCase());

    /* Detect Chrome */
    if($.browser.chrome){
        /* Do something for Chrome at this point */
        /* Finally, if it is Chrome then jQuery thinks it's 
           Safari so we have to tell it isn't */
        $.browser.safari = false;
    }

    /* Detect Safari */
    if($.browser.safari){
        /* Do something for Safari */
    }

});

Case 3: (Using jQuery and $.browser, "elegant" solution)

Live Demo: http://jsfiddle.net/oscarj24/uJuEU/

$.browser.chrome = $.browser.webkit && !!window.chrome;
$.browser.safari = $.browser.webkit && !window.chrome;

if ($.browser.chrome) alert("You are using Chrome!");
if ($.browser.safari) alert("You are using Safari!");

Try the following:

POJO pojo = mapper.convertValue(singleObject, POJO.class);

or:

List<POJO> pojos = mapper.convertValue(
    listOfObjects,
    new TypeReference<List<POJO>>() { });

See conversion of LinkedHashMap for more information.

yes, there is:

object[] x = new object[2];

x[0] = new { firstName = "john", lastName = "walter" };
x[1] = new { brand = "BMW" };

you were practically there, just the declaration of the anonymous types was a little off.

You can export the variable from first file using export.

//first.js
const colorCode = {
    black: "#000",
    white: "#fff"
};
export { colorCode };

Then, import the variable in second file using import.

//second.js
import { colorCode } from './first.js'

export - MDN

The following example demonstrates how to do this:

DateTime a = new DateTime(2010, 05, 12, 13, 15, 00);
DateTime b = new DateTime(2010, 05, 12, 13, 45, 00);
Console.WriteLine(b.Subtract(a).TotalMinutes);

When executed this prints "30" since there is a 30 minute difference between the date/times.

The result of DateTime.Subtract(DateTime x) is a TimeSpan Object which gives other useful properties.

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

Keep it simple

dataGridView1.Columns.Add("newColumnName", "Column Name in Text");

To add rows

dataGridView1.Rows.Add("Value for column#1"); // [,"column 2",...]

As the title suggests that we want to adjust the size of the labels and not the tick marks I figured that I actually might add something to the question, you need to use the mtext() if you want to specify one of the label sizes, or you can just use par(cex.lab=2) as a simple alternative. Here's a more advanced mtext() example:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data=foo,
     yaxt="n", ylab="", 
     xlab="Regular boring x", 
     pch=16,
     col="darkblue")
axis(2,cex.axis=1.2)
mtext("Awesome Y variable", side=2, line=2.2, cex=2)

You may need to adjust the line= option to get the optimal positioning of the text but apart from that it's really easy to use.

My simple answer.

def get_files_tree(src="src_path"):
    req_files = []
    for r, d, files in os.walk(src):
        for file in files:
            src_file = os.path.join(r, file)
            src_file = src_file.replace('\\', '/')
            if src_file.endswith('.db'):
                continue
            req_files.append(src_file)

    return req_files
def copy_tree_force(src_path="",dest_path=""):
    """
    make sure that all the paths has correct slash characters.
    """
    for cf in get_files_tree(src=src_path):
        df= cf.replace(src_path, dest_path)
        if not os.path.exists(os.path.dirname(df)):
            os.makedirs(os.path.dirname(df))
        shutil.copy2(cf, df)

Make a call to the DB searching with myid (Id of the row) and get back specific columns:

var columns = db.Notifications
                .Where(x => x.Id == myid)
                .Select(n => new { n.NotificationTitle, 
                                   n.NotificationDescription, 
                                   n.NotificationOrder });

for i in count: means for i in 7:, which won't work. The bit after the in should be of an iterable type, not a number. Try this:

for i in range(count):

This is also an option:

x==2 && dosomething();

dosomething() will only be called if x==2 is evaluated to true. This is called Short-circuiting.

It is not commonly used in cases like this and you really shouldn't write code like this. I encourage this simpler approach:

if(x==2) dosomething();

You should write readable code at all times; if you are worried about file size, just create a minified version of it with help of one of the many JS compressors. (e.g Google's Closure Compiler)

np.isnan can be applied to NumPy arrays of native dtype (such as np.float64):

In [99]: np.isnan(np.array([np.nan, 0], dtype=np.float64))
Out[99]: array([ True, False], dtype=bool)

but raises TypeError when applied to object arrays:

In [96]: np.isnan(np.array([np.nan, 0], dtype=object))
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Since you have Pandas, you could use pd.isnull instead -- it can accept NumPy arrays of object or native dtypes:

In [97]: pd.isnull(np.array([np.nan, 0], dtype=float))
Out[97]: array([ True, False], dtype=bool)

In [98]: pd.isnull(np.array([np.nan, 0], dtype=object))
Out[98]: array([ True, False], dtype=bool)

Note that None is also considered a null value in object arrays.

I have a simple workaround.

Suppose your URI has a string stringdata that is too long. You can simply break it into a number of parts depending on the limits of your server. Then submit the first one, in my case to write a file. Then submit the next ones to append to previously added data.

The other answers are correct. However, I sometimes find that I want to open the figure object later. For example, I might want to change the label sizes, add a grid, or do other processing. In a perfect world, I would simply rerun the code generating the plot, and adapt the settings. Alas, the world is not perfect. Therefore, in addition to saving to PDF or PNG, I add:

with open('some_file.pkl', "wb") as fp:
    pickle.dump(fig, fp, protocol=4)

Like this, I can later load the figure object and manipulate the settings as I please.

I also write out the stack with the source-code and locals() dictionary for each function/method in the stack, so that I can later tell exactly what generated the figure.

NB: Be careful, as sometimes this method generates huge files.

I'm interpreting your question to be about getting row numbers.

• You can try as.numeric(rownames(df)) if you haven't set the rownames. Otherwise use a sequence of 1:nrow(df).
• The which() function converts a TRUE/FALSE row index into row numbers.

AMD

• introduced in JavaScript to scale JavaScript project into multiple files
• mostly used in browser based application and libraries
• popular implementation is RequireJS, Dojo Toolkit

CommonJS:

• it is specification to handle large number of functions, files and modules of big project
• initial name ServerJS introduced in January, 2009 by Mozilla
• renamed in August, 2009 to CommonJS to show the broader applicability of the APIs
• initially implementation were server, nodejs, desktop based libraries

Example

upper.js file

exports.uppercase = str => str.toUpperCase()

main.js file

const uppercaseModule = require('uppercase.js')
uppercaseModule.uppercase('test')

Summary

• AMD – one of the most ancient module systems, initially implemented by the library require.js.
• CommonJS – the module system created for Node.js server.
• UMD – one more module system, suggested as a universal one, compatible with AMD and CommonJS.

There is a cleaner and ways faster solution than the 'Math.Truncate' approach:

double frac = value % 1;

I solved the above problem in Kotlin that works fine for me for my Android Apps Development:

 object FieldMapper {

fun <T:Any> copy(to: T, from: T) {
    try {
        val fromClass = from.javaClass

        val fromFields = getAllFields(fromClass)

        fromFields?.let {
            for (field in fromFields) {
                try {
                    field.isAccessible = true
                    field.set(to, field.get(from))
                } catch (e: IllegalAccessException) {
                    e.printStackTrace()
                }

            }
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }

}

private fun getAllFields(paramClass: Class<*>): List<Field> {

    var theClass:Class<*>? = paramClass
    val fields = ArrayList<Field>()
    try {
        while (theClass != null) {
            Collections.addAll(fields, *theClass?.declaredFields)
            theClass = theClass?.superclass
        }
    }catch (e:Exception){
        e.printStackTrace()
    }

    return fields
}

}

Using can also use Java 8 stream API and do the same thing in one line.

If you want to print any specific property then use this syntax:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> System.out.println(room.getName()));

OR

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> {
    // here room is available
});

if you want to print all the properties of Java object then use this:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(System.out::println);

Here's a demo on JSFiddle and a snippet:

.numberCircle {_x000D_
    border-radius: 50%;_x000D_
    width: 36px;_x000D_
    height: 36px;_x000D_
    padding: 8px;_x000D_

    text-align: center;_x000D_
_x000D_
    font: 32px Arial, sans-serif;_x000D_
}

<div class="numberCircle">30</div>

My answer is a good starting point, some of the other answers provide flexibility for different situations. If you care about IE8, look at the old version of my answer.

Yes, very right that the -R option in chmod command makes the files/sub-directories under the given directory will get 777 permission. But generally, it's not a good practice to give 777 to all files and dirs as it can lead to data insecurity. Try to be very specific on giving all rights to all files and directories. And to answer your question:

chmod -R 777 your_directory_name

... will work

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

I had this error message with boot2docker on windows with the docker-oracle-xe-11g image (https://registry.hub.docker.com/u/wnameless/oracle-xe-11g/).

The reason was that the virtual box disk was full (check with boot2docker.exe ssh df). Deleting old images and restarting the container solved the problem.

The following is a native js solution.

To clear all rows that have data I use two variables like this. I like this because you can adjust it to a certain range of columns if you need to. Dim CRow As Integer Dim LastRow As Integer

CRow = 1
LastRow = Cells(Rows.Count, 3).End(xlUp).Row

Do Until CRow = LastRow + 1
    Cells(CRow, 1).Value = Empty
    Cells(CRow, 2).Value = Empty
    Cells(CRow, 3).Value = Empty
    Cells(CRow, 4).Value = Empty
    CRow = CRow + 1
Loop

The list() function ^[docs] will convert a string into a list of single-character strings.

>>> list('hello')
['h', 'e', 'l', 'l', 'o']

Even without converting them to lists, strings already behave like lists in several ways. For example, you can access individual characters (as single-character strings) using brackets:

>>> s = "hello"
>>> s[1]
'e'
>>> s[4]
'o'

You can also loop over the characters in the string as you can loop over the elements of a list:

>>> for c in 'hello':
...     print c + c,
... 
hh ee ll ll oo

        target.setUTCDate(target.getUTCDate() - dayNumber + 3);
        firstThursday = target.valueOf();
        target.setUTCMonth(0, 1);

        if (target.getUTCDay() !== 4) {
            target.setUTCMonth(0, 1 + ((4 - target.getUTCDay()) + 7) % 7);
        }

        return Math.ceil((firstThursday - target) /  (7 * 24 * 3600 * 1000)) + 1;
    }

Following code is timezone-independent (UTC dates used) and works according to the https://en.wikipedia.org/wiki/ISO_8601

The requests.Session() solution assisted with logging into a form with CSRF Protection (as used in Flask-WTF forms). Check if a csrf_token is required as a hidden field and add it to the payload with the username and password:

import requests
from bs4 import BeautifulSoup

payload = {
    'email': '[email protected]',
    'password': 'passw0rd'
}     

with requests.Session() as sess:
    res = sess.get(server_name + '/signin')
    signin = BeautifulSoup(res._content, 'html.parser')
    payload['csrf_token'] = signin.find('input', id='csrf_token')['value']
    res = sess.post(server_name + '/auth/login', data=payload)

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

Copy the global variable to a variable in the scope in your controller.

function MyCtrl($scope) {
   $scope.variable1 = variable1;
}

Then you can just access it like you tried. But note that this variable will not change when you change the global variable. If you need that, you could instead use a global object and "copy" that. As it will be "copied" by reference, it will be the same object and thus changes will be applied (but remember that doing stuff outside of AngularJS will require you to do $scope.$apply anway).

But maybe it would be worthwhile if you would describe what you actually try to achieve. Because using a global variable like this is almost never a good idea and there is probably a better way to get to your intended result.

The fix for the heartbleed vulnerability has been backported to 1.0.1e-16 by Red Hat for Enterprise Linux see, and this is therefore the official fix that CentOS ships.

Replacing OpenSSL with the latest version from upstream (i.e. 1.0.1g) runs the risk of introducing functionality changes which may break compatibility with applications/clients in unpredictable ways, causes your system to diverge from RHEL, and puts you on the hook for personally maintaining future updates to that package. By replacing openssl using a simple make config && make && make install means that you also lose the ability to use rpm to manage that package and perform queries on it (e.g. verifying all the files are present and haven't been modified or had permissions changed without also updating the RPM database).

I'd also caution that crypto software can be extremely sensitive to seemingly minor things like compiler options, and if you don't know what you're doing, you could introduce vulnerabilities in your local installation.

iOS Status bar has only 2 options (black and white). You can try this in AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
}

If you want to keep your working changes while performing a rebase, you can use --autostash. From the documentation:

Before starting rebase, stash local modifications away (see git-stash[1]) if needed, and apply the stash when done.

For example:

git pull --rebase --autostash

I stumbled upon this question because I created, successfully built and published a PyPI Package, but couldn't execute it after installation. The $PATHvariable was correctly set.

In my case the problem was that I hadn't set the entry_pointin the setup.py file:

entry_points = {'console_scripts':

['YOUR_CONSOLE_COMMAND=MODULE_NAME.FILE_NAME:FUNCTION_NAME'],},

It's a very old post, but if it benefits anyone, we can do something like this:

Long max=((BigInteger) Collections.max(dynamics)).longValue(); 

just use scrollTo plugin

$("document").ready(function(){
  $(window).scrollTo("#div")
})

Number one problem? They only test on toy databases. So they have no idea that their SQL will crawl when the database gets big, and someone has to come along and fix it later (that sound you can hear is my teeth grinding).

You are sending a post type with data implemented for a get. your form must be the following:

$.ajax({
url: url,
method: "POST",
data: {data1:"data1",data2:"data2"},
...

Depending on what kind of List you want to use, something like

List<String> supplierNames = new ArrayList<String>();

should get you going.

List is the interface, ArrayList is one implementation of the List interface. More implementations that may better suit your needs can be found by reading the JavaDocs of the List interface.

In WinForm, we can always get the Control Key status by:

bool IsCtrlPressed = (Control.ModifierKeys & Keys.Control) != 0;

Remove it from the adapter and then notify the arrayadapter that data set has changed.

m_adapter.remove(o);
m_adapter.notifyDataSetChanged();

Use this style

<div class="form-control"
     style="height:100px;
     width:55%;
     overflow:hidden;
     cursor:pointer">
</div>

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

According to http://developer.android.com/guide/topics/ui/actionbar.html

The ActionBar APIs were first added in Android 3.0 (API level 11) but they are also available in the Support Library for compatibility with Android 2.1 (API level 7) and above.

In short, that auto-generated project you're seeing modularizes the process of adding the ActionBar to APIs 7-10.

See http://hmkcode.com/add-actionbar-to-android-2-3-x/ for a simplified explanation and tutorial on the topic.

The standard way to pass a list of values as URL parameters is to repeat them:

http://our.api.com/Product?id=101404&id=7267261

Most server code will interpret this as a list of values, although many have single value simplifications so you may have to go looking.

Delimited values are also okay.

If you are needing to send JSON to the server, I don't like seeing it in in the URL (which is a different format). In particular, URLs have a size limitation (in practice if not in theory).

The way I have seen some do a complicated query RESTfully is in two steps:

1. POST your query requirements, receiving back an ID (essentially creating a search criteria resource)
2. GET the search, referencing the above ID
3. optionally DELETE the query requirements if needed, but note that they requirements are available for reuse.

The 2 main reason why you might want to prefer Mongo are

• Flexibility in schema design (JSON type document store).
• Scalability - Just add up nodes and it can scale horizontally quite well.

It is suitable for big data applications. RDBMS is not good for big data.

//: Playground - noun: a place where people can play

import UIKit

class A {
    class func a() {
        print("yeah")
    }

    func getInnerValue() {
        self.dynamicType.a()
    }
}

class B: A {
    override class func a() {
        print("yeah yeah")
    }
}

B.a() // yeah yeah
A.a() // yeah
B().getInnerValue() // yeah yeah
A().getInnerValue() // yeah

I had the same issue with resharper and I corrected this error by changing an option:

Resharper => Options => Tools => Unit Testing

I just had to uncheck the option "Shadow-copy assemblies being tested"

To replace from the right:

def replace_right(source, target, replacement, replacements=None):
    return replacement.join(source.rsplit(target, replacements))

In use:

>>> replace_right("asd.asd.asd.", ".", ". -", 1)
'asd.asd.asd. -'

as above, but qualitatively:

private - least access, best encapsulation
protected - some access, moderate encapsulation
public - full access, no encapsulation

the less access you provide the fewer implementation details leak out of your objects. less of this sort of leakage means more flexibility (aka "looser coupling") in terms of changing how an object is implemented without breaking clients of the object. this is a truly fundamental thing to understand.

Set up a virtualenv:

% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py 
% sudo python /tmp/get-pip.py

These commands install pip into the global site-packages directory.

% sudo pip install virtualenv

and ditto for virtualenv:

% mkdir -p ~/.virtualenvs

I like my virtualenvs under one tree in my home directory called .virtualenvs

% virtualenv ~/.virtualenvs/lxmltest

Creates a virtualenv.

% . ~/.virtualenvs/lxmltest/bin/activate

Removes the need to specify the full path to pip/python in this virtualenv.

% pip install lxml

Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxml if you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltest and start again from a new virtualenv.

if(array.indexOf("67") != -1) // is in array

There is a good article on MDN that explains the theory behind those concepts: https://developer.mozilla.org/en-US/docs/Web/API/CSS_Object_Model/Determining_the_dimensions_of_elements

It also explains the important conceptual differences between boundingClientRect's width/height vs offsetWidth/offsetHeight.

Then, to prove the theory right or wrong, you need some tests. That's what I did here: https://github.com/lingtalfi/dimensions-cheatsheet

It's testing for chrome53, ff49, safari9, edge13 and ie11.

The results of the tests prove that the theory is generally right. For the tests, I created 3 divs containing 10 lorem ipsum paragraphs each. Some css was applied to them:

.div1{
    width: 500px;
    height: 300px;
    padding: 10px;
    border: 5px solid black;
    overflow: auto;
}
.div2{
    width: 500px;
    height: 300px;
    padding: 10px;
    border: 5px solid black;
    box-sizing: border-box;
    overflow: auto;
}

.div3{
    width: 500px;
    height: 300px;
    padding: 10px;
    border: 5px solid black;
    overflow: auto;
    transform: scale(0.5);
}

And here are the results:

• div1

  • offsetWidth: 530 (chrome53, ff49, safari9, edge13, ie11)
  • offsetHeight: 330 (chrome53, ff49, safari9, edge13, ie11)
  • bcr.width: 530 (chrome53, ff49, safari9, edge13, ie11)

  • bcr.height: 330 (chrome53, ff49, safari9, edge13, ie11)

  • clientWidth: 505 (chrome53, ff49, safari9)

  • clientWidth: 508 (edge13)
  • clientWidth: 503 (ie11)

  • clientHeight: 320 (chrome53, ff49, safari9, edge13, ie11)

  • scrollWidth: 505 (chrome53, safari9, ff49)

  • scrollWidth: 508 (edge13)
  • scrollWidth: 503 (ie11)
  • scrollHeight: 916 (chrome53, safari9)
  • scrollHeight: 954 (ff49)
  • scrollHeight: 922 (edge13, ie11)

• div2

  • offsetWidth: 500 (chrome53, ff49, safari9, edge13, ie11)
  • offsetHeight: 300 (chrome53, ff49, safari9, edge13, ie11)
  • bcr.width: 500 (chrome53, ff49, safari9, edge13, ie11)
  • bcr.height: 300 (chrome53, ff49, safari9)
  • bcr.height: 299.9999694824219 (edge13, ie11)
  • clientWidth: 475 (chrome53, ff49, safari9)
  • clientWidth: 478 (edge13)
  • clientWidth: 473 (ie11)

  • clientHeight: 290 (chrome53, ff49, safari9, edge13, ie11)

  • scrollWidth: 475 (chrome53, safari9, ff49)

  • scrollWidth: 478 (edge13)
  • scrollWidth: 473 (ie11)
  • scrollHeight: 916 (chrome53, safari9)
  • scrollHeight: 954 (ff49)
  • scrollHeight: 922 (edge13, ie11)

• div3

  • offsetWidth: 530 (chrome53, ff49, safari9, edge13, ie11)
  • offsetHeight: 330 (chrome53, ff49, safari9, edge13, ie11)
  • bcr.width: 265 (chrome53, ff49, safari9, edge13, ie11)
  • bcr.height: 165 (chrome53, ff49, safari9, edge13, ie11)
  • clientWidth: 505 (chrome53, ff49, safari9)
  • clientWidth: 508 (edge13)
  • clientWidth: 503 (ie11)

  • clientHeight: 320 (chrome53, ff49, safari9, edge13, ie11)

  • scrollWidth: 505 (chrome53, safari9, ff49)

  • scrollWidth: 508 (edge13)
  • scrollWidth: 503 (ie11)
  • scrollHeight: 916 (chrome53, safari9)
  • scrollHeight: 954 (ff49)
  • scrollHeight: 922 (edge13, ie11)

So, apart from the boundingClientRect's height value (299.9999694824219 instead of expected 300) in edge13 and ie11, the results confirm that the theory behind this works.

From there, here is my definition of those concepts:

• offsetWidth/offsetHeight: dimensions of the layout border box
• boundingClientRect: dimensions of the rendering border box
• clientWidth/clientHeight: dimensions of the visible part of the layout padding box (excluding scroll bars)
• scrollWidth/scrollHeight: dimensions of the layout padding box if it wasn't constrained by scroll bars

Note: the default vertical scroll bar's width is 12px in edge13, 15px in chrome53, ff49 and safari9, and 17px in ie11 (done by measurements in photoshop from screenshots, and proven right by the results of the tests).

However, in some cases, maybe your app is not using the default vertical scroll bar's width.

So, given the definitions of those concepts, the vertical scroll bar's width should be equal to (in pseudo code):

• layout dimension: offsetWidth - clientWidth - (borderLeftWidth + borderRightWidth)

• rendering dimension: boundingClientRect.width - clientWidth - (borderLeftWidth + borderRightWidth)

Note, if you don't understand layout vs rendering please read the mdn article.

Also, if you have another browser (or if you want to see the results of the tests for yourself), you can see my test page here: http://codepen.io/lingtalfi/pen/BLdBdL

you could use "AUTHID CURRENT_USER" in body of your procedure definition for your requirements.

If you use androidx.* classes in your project, you should use HtmlCompat.fromHtml(text, flag).

Source of the method is:

@NonNull
    public static Spanned fromHtml(@NonNull String source, @FromHtmlFlags int flags) {
        if (Build.VERSION.SDK_INT >= 24) {
            return Html.fromHtml(source, flags);
        }
        //noinspection deprecation
        return Html.fromHtml(source);
    }

It is better to use HtmlCompat.fromHtml than Html.fromHtml as there is less code- only one line of code, and it's recommended way to use it.

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

As of Java 8, some local variable name information is available through reflection. See the "Update" section below.

Complete information is often stored in class files. One compile-time optimization is to remove it, saving space (and providing some obsfuscation). However, when it is is present, each method has a local variable table attribute that lists the type and name of local variables, and the range of instructions where they are in scope.

Perhaps a byte-code engineering library like ASM would allow you to inspect this information at runtime. The only reasonable place I can think of for needing this information is in a development tool, and so byte-code engineering is likely to be useful for other purposes too.

Update: Limited support for this was added to Java 8. Parameter (a special class of local variable) names are now available via reflection. Among other purposes, this can help to replace @ParameterName annotations used by dependency injection containers.

I am new to Scala, but how about this to avoid throwing exceptions and repeating methods:

object awhile {
def apply(condition: () => Boolean, action: () => breakwhen): Unit = {
    while (condition()) {
        action() match {
            case breakwhen(true)    => return ;
            case _                  => { };
        }
    }
}
case class breakwhen(break:Boolean);

use it like this:

var i = 0
awhile(() => i < 20, () => {
    i = i + 1
    breakwhen(i == 5)
});
println(i)

if you don’t want to break:

awhile(() => i < 20, () => {
    i = i + 1
    breakwhen(false)
});

I was having the same problem too, how to debug JavaScript that is inside <script> tags. But then I found it under the Sources tab, called "(index)", with parenthesis. Click the line number to set breakpoints.

This is Chrome 71.

Try this: (even [1] will be removed)

> cat(noquote("love"))
love

else just use noquote

> noquote("love")
[1] love

If you use the native array sort function, you can pass in a custom comparator to be used when sorting the array. The comparator should return a negative number if the first value is less than the second, zero if they're equal, and a positive number if the first value is greater.

So if I understand the example you're giving correctly, you could do something like:

function sortFunc(a, b) {
  var sortingArr = [ 'b', 'c', 'b', 'b', 'c', 'd' ];
  return sortingArr.indexOf(a[1]) - sortingArr.indexOf(b[1]);
}

itemsArray.sort(sortFunc);

The best way to install plugin using SSH is WPCLI.

Note that, SSH access is mandatory to use WP CLI commands. Before using it check whether the WP CLI is installed at your hosting server or machine.

How to check : wp --version [ It will show the wp cli version installed ]

If not installed, how to install it : Before installing WP-CLI, please make sure the environment meets the minimum requirements:

UNIX-like environment (OS X, Linux, FreeBSD, Cygwin); limited support in Windows environment. PHP 5.4 or later WordPress 3.7 or later. Versions older than the latest WordPress release may have degraded functionality

If above points satisfied, please follow the steps : Reference URL : WPCLI

curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
[ download the wpcli phar ]

php wp-cli.phar --info [ check whether the phar file is working ]

chmod +x wp-cli.phar [ change permission ]
sudo mv wp-cli.phar /usr/local/bin/wp [ move to global folder ]
wp --info [ to check the installation ]

Now WP CLI is ready to install.

Now you can install any plugin that is available in WordPress.org by using the following commands :

wp install plugin plugin-slug
wp delete plugin plugin-slug
wp deactivate plugin plugin-slug

NOTE : wp cli can install only those plugin which is available in wordpress.org

Just use floatval().

E.g.:

$var = '122.34343';
$float_value_of_var = floatval($var);
echo $float_value_of_var; // 122.34343

And in case you wonder doubleval() is just an alias for floatval().

And as the other say, in a financial application, float values are critical as these are not precise enough. E.g. adding two floats could result in something like 12.30000000001 and this error could propagate.

There is the potential for a subtle bug in your code.

[UPDATE: Since he's using map.remove() this description isn't totally valid. I missed that fact the first time thru. :( Thanks to the question's author for pointing that out. I'm leaving the rest as is, but changed the lead statement to say there is potentially a bug.]

In doWork() you get the List value from the Map in a thread-safe way. Afterward, however, you are accessing that list in an unsafe matter. For instance, one thread may be using the list in doWork() while another thread invokes synchronizedMap.get(key).add(value) in addToMap(). Those two access are not synchronized. The rule of thumb is that a collection's thread-safe guarantees don't extend to the keys or values they store.

You could fix this by inserting a synchronized list into the map like

List<String> valuesList = new ArrayList<String>();
valuesList.add(value);
synchronizedMap.put(key, Collections.synchronizedList(valuesList)); // sync'd list

Alternatively you could synchronize on the map while you access the list in doWork():

  public void doWork(String key) {
    List<String> values = null;
    while ((values = synchronizedMap.remove(key)) != null) {
      synchronized (synchronizedMap) {
          //do something with values
      }
    }
  }

The last option will limit concurrency a bit, but is somewhat clearer IMO.

Also, a quick note about ConcurrentHashMap. This is a really useful class, but is not always an appropriate replacement for synchronized HashMaps. Quoting from its Javadocs,

This class is fully interoperable with Hashtable in programs that rely on its thread safety but not on its synchronization details.

In other words, putIfAbsent() is great for atomic inserts but does not guarantee other parts of the map won't change during that call; it guarantees only atomicity. In your sample program, you are relying on the synchronization details of (a synchronized) HashMap for things other than put()s.

Last thing. :) This great quote from Java Concurrency in Practice always helps me in designing an debugging multi-threaded programs.

For each mutable state variable that may be accessed by more than one thread, all accesses to that variable must be performed with the same lock held.

To specify more than one namespace to provide prefixes, use something like:

@javax.xml.bind.annotation.XmlSchema(
    namespace = "urn:oecd:ties:cbc:v1", 
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
    xmlns ={@XmlNs(prefix="cbc", namespaceURI="urn:oecd:ties:cbc:v1"), 
            @XmlNs(prefix="iso", namespaceURI="urn:oecd:ties:isocbctypes:v1"),
            @XmlNs(prefix="stf", namespaceURI="urn:oecd:ties:stf:v4")})

... in package-info.java

Add cors mode to prevent files cors blocked

fetch(url,{mode:"cors"})
                    .then(res => res.blob())
                    .then(blob => {
                        const file = new File([blob], 'dot.png', {type:'image/png'});
                        console.log(file);
                    });

Take a look at numpy.reshape .

>>> arr = numpy.zeros((50,100,25))
>>> arr.shape
# (50, 100, 25)

>>> new_arr = arr.reshape(5000,25)
>>> new_arr.shape   
# (5000, 25)

# One shape dimension can be -1. 
# In this case, the value is inferred from 
# the length of the array and remaining dimensions.
>>> another_arr = arr.reshape(-1, arr.shape[-1])
>>> another_arr.shape
# (5000, 25)

I wrote a reallllllllllllllllly simple plugin for myself several years ago:

To add to your page all you need to do is put this in the head:

<script src="https://jackcrane.github.io/static/cdn/jconsole.js" type="text/javascript">

Then in JS:

jconsole.color.red.log('hellllooo world');

The framework has code for:

jconsole.color.red.log();
jconsole.color.orange.log();
jconsole.color.yellow.log();
jconsole.color.green.log();
jconsole.color.blue.log();
jconsole.color.purple.log();
jconsole.color.teal.log();

as well as:

jconsole.css.log("hello world","color:red;");

for any other css. The above is designed with the following syntax:

jconsole.css.log(message to log,css code to style the logged message)

A BigDecimal is an exact way of representing numbers. A Double has a certain precision. Working with doubles of various magnitudes (say d1=1000.0 and d2=0.001) could result in the 0.001 being dropped alltogether when summing as the difference in magnitude is so large. With BigDecimal this would not happen.

The disadvantage of BigDecimal is that it's slower, and it's a bit more difficult to program algorithms that way (due to + - * and / not being overloaded).

If you are dealing with money, or precision is a must, use BigDecimal. Otherwise Doubles tend to be good enough.

I do recommend reading the javadoc of BigDecimal as they do explain things better than I do here :)

From MS's Patterns & Practices documentation:

Data Validation and Error Reporting

Your view model or model will often be required to perform data validation and to signal any data validation errors to the view so that the user can act to correct them.

Silverlight and WPF provide support for managing data validation errors that occur when changing individual properties that are bound to controls in the view. For single properties that are data-bound to a control, the view model or model can signal a data validation error within the property setter by rejecting an incoming bad value and throwing an exception. If the ValidatesOnExceptions property on the data binding is true, the data binding engine in WPF and Silverlight will handle the exception and display a visual cue to the user that there is a data validation error.

However, throwing exceptions with properties in this way should be avoided where possible. An alternative approach is to implement the IDataErrorInfo or INotifyDataErrorInfo interfaces on your view model or model classes. These interfaces allow your view model or model to perform data validation for one or more property values and to return an error message to the view so that the user can be notified of the error.

The documentation goes on to explain how to implement IDataErrorInfo and INotifyDataErrorInfo.

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

$url = "http://user:[email protected]/abc.php?var1=def";
$contents = file_get_contents($url);
echo $contents;

Here's a simple example. I didn't get fancy with the html or the servlet, but you should get the idea.

I hope this helps you out.

<html>
<body>
<form method="post" action="/myServlet">
<input type="text" name="username" />
<input type="password" name="password" />
<input type="submit" />
</form>
</body>
</html>

Now for the Servlet

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class MyServlet extends HttpServlet {
  public void doPost(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {

    String userName = request.getParameter("username");
    String password = request.getParameter("password");
    ....
    ....
  }
}

you will get the time without specifying the date format. convert the string to date using Date object

var myDate = new Date('Mon 03-Jul-2017, 06:00 PM');

working solution:

var myDate= new Date('Mon 03-Jul-2017, 06:00 PM');_x000D_
console.log(moment(myDate).format('HH:mm')); // 24 hour format _x000D_
console.log(moment(myDate).format('hh:mm'));_x000D_
console.log(moment(myDate).format('hh:mm A'));

For Word 2010 and 2013, go to File > Options > Customize Ribbon > Keyboard Shortcuts > All Commands (in left list) > Color: (in right list) -- at this point, you type in the short cut (such as Alt+r) and select the color (such as red). (This actually goes back to 2003 but I don't have that installed to provide the pathway.)

There is actually a much faster alternative to convert binary numbers to decimal, based on artificial intelligence (linear regression) model:

1. Train an AI algorithm to convert 32-binary number to decimal based.
2. Predict a decimal representation from 32-binary.

See example and time comparison below:

from sklearn.linear_model import LinearRegression
from sklearn.model_selection import train_test_split
import numpy as np

y = np.random.randint(0, 2**32, size=10_000)

def gen_x(y):
    _x = bin(y)[2:]
    n = 32 - len(_x)
    return [int(sym) for sym in '0'*n + _x]

X = np.array([gen_x(x) for x in y])

model = LinearRegression()
model.fit(X, y)

def convert_bin_to_dec_ai(array):
    return model.predict(array)

y_pred = convert_bin_to_dec_ai(X)

Time comparison:

This AI solution converts numbers almost x10 times faster than conventional way!

Sadly, this is not possible by default to use section as another user suggested, since a section is only available to the immediate child of a View.

What works however is implementing and redefining the section in every view, meaning:

section Head
{
    @RenderSection("Head", false)
}

This way every view can implement a head section, not just the immediate children. This only works partly though, especially with multiple partials the troubles begin (as you have mentioned in your question).

So the only real solution to your problem is using the ViewBag. The best would probably be a seperate collection (list) for CSS and scripts. For this to work, you need to ensure that the List used is initialized before any of the views are executed. Then you can can do things like this in the top of every view/partial (without caring if the Scripts or Styles value is null:

ViewBag.Scripts.Add("myscript.js");
ViewBag.Styles.Add("mystyle.css");

In the layout you can then loop through the collections and add the styles based on the values in the List.

@foreach (var script in ViewBag.Scripts)
{
    <script type="text/javascript" src="@script"></script>
}
@foreach (var style in ViewBag.Styles)
{
    <link href="@style" rel="stylesheet" type="text/css" />
}

I think it's ugly, but it's the only thing that works.

******UPDATE**** Since it starts executing the inner views first and working its way out to the layout and CSS styles are cascading, it would probably make sense to reverse the style list via ViewBag.Styles.Reverse().

This way the most outer style is added first, which is inline with how CSS style sheets work anyway.

Should you be interested in creating the 'ctor' or a similar class-name-injecting snippet from scratch, create a .snippet file in the C# snippets directory (for example C:\VS2017\VC#\Snippets\1033\Visual C#\C#Snippets.snippet) with this XML content:

<CodeSnippets>
    <CodeSnippet>
        <Header>
            <Title>ctor</Title>
            <Shortcut>ctor</Shortcut>
        </Header>
        <Snippet>
            <Declarations>
                <Literal Editable="false"><ID>classname</ID><Function>ClassName()</Function></Literal>
            </Declarations>
            <Code>
                <![CDATA[public $classname$($end$)
                {

                }]]>
            </Code>
        </Snippet>
    </CodeSnippet>

I wrote some PowerShell utilities for retrieving version information from Git and simplifying tagging

functions: Get-LastVersion, Get-Revision, Get-NextMajorVersion, Get-NextMinorVersion, TagNextMajorVersion, TagNextMinorVersion:

# Returns the last version by analysing existing tags,
# assumes an initial tag is present, and
# assumes tags are named v{major}.{minor}.[{revision}]
#
function Get-LastVersion(){
  $lastTagCommit = git rev-list --tags --max-count=1
  $lastTag = git describe --tags $lastTagCommit
  $tagPrefix = "v"
  $versionString = $lastTag -replace "$tagPrefix", ""
  Write-Host -NoNewline "last tagged commit "
  Write-Host -NoNewline -ForegroundColor "yellow" $lastTag
  Write-Host -NoNewline " revision "
  Write-Host -ForegroundColor "yellow" "$lastTagCommit"
  [reflection.assembly]::LoadWithPartialName("System.Version")

  $version = New-Object System.Version($versionString)
  return $version;
}

# Returns current revision by counting the number of commits to HEAD
function Get-Revision(){
   $lastTagCommit = git rev-list HEAD
   $revs  = git rev-list $lastTagCommit |  Measure-Object -Line
   return $revs.Lines
}

# Returns the next major version {major}.{minor}.{revision}
function Get-NextMajorVersion(){
    $version = Get-LastVersion;
    [reflection.assembly]::LoadWithPartialName("System.Version")
    [int] $major = $version.Major+1;
    $rev = Get-Revision
    $nextMajor = New-Object System.Version($major, 0, $rev);
    return $nextMajor;
}

# Returns the next minor version {major}.{minor}.{revision}
function Get-NextMinorVersion(){
    $version = Get-LastVersion;
    [reflection.assembly]::LoadWithPartialName("System.Version")
    [int] $minor = $version.Minor+1;
    $rev = Get-Revision
    $next = New-Object System.Version($version.Major, $minor, $rev);
    return $next;
}

# Creates a tag with the next minor version
function TagNextMinorVersion($tagMessage){
    $version = Get-NextMinorVersion;
    $tagName = "v{0}" -f "$version".Trim();
    Write-Host -NoNewline "Tagging next minor version to ";
    Write-Host -ForegroundColor DarkYellow "$tagName";
    git tag -a $tagName -m $tagMessage
}

# Creates a tag with the next major version (minor version starts again at 0)
function TagNextMajorVersion($tagMessage){
    $version = Get-NextMajorVersion;
    $tagName = "v{0}" -f "$version".Trim();
    Write-Host -NoNewline "Tagging next majo version to ";
    Write-Host -ForegroundColor DarkYellow "$tagName";
    git tag -a $tagName -m $tagMessage
}

With CSS:

selector { cursor: none; }

An example:

<div class="nocursor">_x000D_
   Some stuff_x000D_
</div>_x000D_
<style type="text/css">_x000D_
    .nocursor { cursor:none; }_x000D_
</style>

To set this on an element in Javascript, you can use the style property:

<div id="nocursor"><!-- some stuff --></div>
<script type="text/javascript">
    document.getElementById('nocursor').style.cursor = 'none';
</script>

If you want to set this on the whole body:

<script type="text/javascript">
    document.body.style.cursor = 'none';
</script>

Make sure you really want to hide the cursor, though. It can really annoy people.

Swift Answer

Here is the custom class, that animates placeholder.

class CustomTextView: UITextView {
    
    //   MARK: - public
    
    public var placeHolderText: String? = "Enter Reason.."
    
    public lazy var placeHolderLabel: UILabel! = {
        let placeHolderLabel = UILabel(frame: .zero)
        placeHolderLabel.numberOfLines = 0
        placeHolderLabel.backgroundColor = .clear
        placeHolderLabel.alpha = 0.5
        return placeHolderLabel
    }()
    
    //   MARK: - Init
    
    override init(frame: CGRect, textContainer: NSTextContainer?) {
        super.init(frame: frame, textContainer: textContainer)
        enableNotifications()
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        enableNotifications()
    }
    
    func setup() {
        placeHolderLabel.frame = CGRect(x: 8, y: 8, width: self.bounds.size.width - 16, height: 15)
        placeHolderLabel.sizeToFit()
    }
    
    //   MARK: - Cycle
    
    override func awakeFromNib() {
        super.awakeFromNib()
        
        textContainerInset = UIEdgeInsets(top: 8, left: 5, bottom: 8, right: 8)
        returnKeyType = .done
        addSubview(placeHolderLabel)
        placeHolderLabel.frame = CGRect(x: 8, y: 8, width: self.bounds.size.width - 16, height: 15)
        placeHolderLabel.textColor = textColor
        placeHolderLabel.font = font
        placeHolderLabel.text = placeHolderText
        bringSubviewToFront(placeHolderLabel)
    }
    
    override func layoutSubviews() {
        super.layoutSubviews()
        setup()
    }
    
    //   MARK: - Notifications
    
    private func enableNotifications() {
        NotificationCenter.default.addObserver(self, selector: #selector(textDidChangeNotification(_:)), name: UITextView.textDidChangeNotification , object: nil)
    }
    
    @objc func textDidChangeNotification(_ notify: Notification) {
        guard self == notify.object as? UITextView else { return }
        guard placeHolderText != nil else { return }
        
        UIView.animate(withDuration: 0.25, animations: {
            self.placeHolderLabel.alpha = (self.text.count == 0) ? 0.5 : 0
        }, completion: nil)
    }
    
}

Use List<T>.Insert

While not relevant to your specific example, if performance is important also consider using LinkedList<T> because inserting an item to the start of a List<T> requires all items to be moved over. See When should I use a List vs a LinkedList.

Instead of doing foreach() loop on the array, it would be faster to use array_search() to find the proper key. On small arrays, I would go with foreach for better readibility, but for bigger arrays, or often executed code, this should be a bit more optimal:

$result=array_search($unwantedValue,$array,true);
if($result !== false) {
  unset($array[$result]);   
}

The strict comparsion operator !== is needed, because array_search() can return 0 as the index of the $unwantedValue.

Also, the above example will remove just the first value $unwantedValue, if the $unwantedValue can occur more then once in the $array, You should use array_keys(), to find all of them:

$result=array_keys($array,$unwantedValue,true)
foreach($result as $key) {
  unset($array[$key]);
}

Check http://php.net/manual/en/function.array-search.php for more information.

The definitive solution is to allow the InfoTech protocol to work in the intranet zone.

In psql alter column query syntax like this

Alter table users add column priv_user boolean default false ;

boolean value (true-false) save in DB like (t-f) value .

I'm not sure that you want to send two SELECT statements in one request statement because you may not be able to access both ResultSets. The database may only return the last result set.

Multiple ResultSets

However, if you're calling a stored procedure that you know can return multiple resultsets something like this will work

CallableStatement stmt = con.prepareCall(...);
try {
...

boolean results = stmt.execute();

while (results) {
    ResultSet rs = stmt.getResultSet();
    try {
    while (rs.next()) {
        // read the data
    }
    } finally {
        try { rs.close(); } catch (Throwable ignore) {}
    }

    // are there anymore result sets?
    results = stmt.getMoreResults();
}
} finally {
    try { stmt.close(); } catch (Throwable ignore) {}
}

Multiple SQL Statements

If you're talking about multiple SQL statements and only one SELECT then your database should be able to support the one String of SQL. For example I have used something like this on Sybase

StringBuffer sql = new StringBuffer( "SET rowcount 100" );
sql.append( " SELECT * FROM tbl_books ..." );
sql.append( " SET rowcount 0" );

stmt = conn.prepareStatement( sql.toString() );

This will depend on the syntax supported by your database. In this example note the addtional spaces padding the statements so that there is white space between the staments.

You can use a sprite which has both version—the colored and the monochrome—stored into it.

To have text-align:center work you need to add that style to the #siteInfo div or wrap the input in a paragraph and add text-align:center to the paragraph.

You can try this way:

$datetime = new DateTime('2010-12-30 23:21:46');

echo $datetime->format(DATE_ATOM);

Here is another way to do it.

import webbrowser

webbrowser.open("foobar.com")

Seems like you can't iterate through JSONArray with a for each. You can loop through your JSONArray like this:

for (int i=0; i < arr.length(); i++) {
    arr.getJSONObject(i);
}

Another way, simpler.

Add your

build.gradle

file to the root of your project. Close the project. Manually remove *.iml file. Then choose "Import Project...", navigate to your project directory, select the build.gradle file and click OK.

At the risk of irritating you;

You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.

Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.

What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.

It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.

In short, it's just unnecessarily conflating the matter when there is no need to.

Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().

Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)

Maximum is 2097151, If you try set more error occurred.

To add to the above: If interrupt is not working, you can restart the kernel.

Go to the kernel dropdown >> restart >> restart and clear output. This usually does the trick. If this still doesn't work, kill the kernel in the terminal (or task manager) and then restart.

Interrupt doesn't work well for all processes. I especially have this problem using the R kernel.

Update: Handling this in CSS is wonderfully simple and low overhead, but you have no control over where breaks occur when they do. That's fine if you don't care, or your data has long alphanumeric runs without any natural breaks. We had lots of long file paths, URLs, and phone numbers, all of which have places it's significantly better to break at than others.

Our solution was to first use a regex replacement to put a zero-width space (​) after every 15 (say) characters that aren't whitespace or one of the special characters where we'd prefer breaks. We then do another replacement to put a zero-width space after those special characters.

Zero-width spaces are nice, because they aren't ever visible on screen; shy hyphens were confusing when they showed, because the data has significant hyphens. Zero-width spaces also aren't included when you copy text out of the browser.

The special break characters we're currently using are period, forward slash, backslash, comma, underscore, @, |, and hyphen. You wouldn't think you'd need do anything to encourage breaking after hyphens, but Firefox (3.6 and 4 at least) doesn't break by itself at hyphens surrounded by numbers (like phone numbers).

We also wanted to control the number of characters between artificial breaks, based on the layout space available. That meant that the regex to match long non-breaking runs needed to be dynamic. This gets called a lot, and we didn't want to be creating the same identical regexes over and over for performance reasons, so we used a simple regex cache, keyed by the regex expression and its flags.

Here's the code; you'd probably namespace the functions in a utility package:

makeWrappable = function(str, position)
{
    if (!str)
        return '';
    position = position || 15; // default to breaking after 15 chars
    // matches every requested number of chars that's not whitespace or one of the special chars defined below
    var longRunsRegex = cachedRegex('([^\\s\\.\/\\,_@\\|-]{' + position + '})(?=[^\\s\\.\/\\,_@\\|-])', 'g');
    return str
                .replace(longRunsRegex, '$1​') // put a zero-width space every requested number of chars that's not whitespace or a special char
                .replace(makeWrappable.SPECIAL_CHARS_REGEX, '$1​'); // and one after special chars we want to allow breaking after
};
makeWrappable.SPECIAL_CHARS_REGEX = /([\.\/\\,_@\|-])/g; // period, forward slash, backslash, comma, underscore, @, |, hyphen


cachedRegex = function(reString, reFlags)
{
    var key = reString + (reFlags ? ':::' + reFlags : '');
    if (!cachedRegex.cache[key])
        cachedRegex.cache[key] = new RegExp(reString, reFlags);
    return cachedRegex.cache[key];
};
cachedRegex.cache = {};

Test like this:

makeWrappable('12345678901234567890 12345678901234567890 1234567890/1234567890')

Update 2: It appears that zero-width spaces in fact are included in copied text in at least some circumstances, you just can't see them. Obviously, encouraging people to copy text with hidden characters in it is an invitation to have data like that entered into other programs or systems, even your own, where it may cause problems. For instance, if it ends up in a database, searches against it may fail, and search strings like this are likely to fail too. Using arrow keys to move through data like this requires (rightly) an extra keypress to move across the character you can't see, somewhat bizarre for users if they notice.

In a closed system, you can filter that character out on input to protect yourself, but that doesn't help other programs and systems.

All told, this technique works well, but I'm not certain what the best choice of break-causing character would be.

Update 3: Having this character end up in data is no longer a theoretical possibility, it's an observed problem. Users submit data copied off the screen, it gets saved in the db, searches break, things sort weirdly etc..

We did two things:

1. Wrote a utility to remove them from all columns of all tables in all datasources for this app.
2. Added filtering to remove it to our standard string input processor, so it's gone by the time any code sees it.

This works well, as does the technique itself, but it's a cautionary tale.

Update 4: We're using this in a context where the data fed to this may be HTML escaped. Under the right circumstances, it can insert zero-width spaces in the middle of HTML entities, with funky results.

Fix was to add ampersand to the list of characters we don't break on, like this:

var longRunsRegex = cachedRegex('([^&\\s\\.\/\\,_@\\|-]{' + position + '})(?=[^&\\s\\.\/\\,_@\\|-])', 'g');

This is a simple question but the answer is surprisingly complex. The short answer is you can do what you're trying to do with std::bind1st or boost::bind. The longer answer is below.

The compiler is correct to suggest you use &CLoggersInfra::RedundencyManagerCallBack. First, if RedundencyManagerCallBack is a member function, the function itself doesn't belong to any particular instance of the class CLoggersInfra. It belongs to the class itself. If you've ever called a static class function before, you may have noticed you use the same SomeClass::SomeMemberFunction syntax. Since the function itself is 'static' in the sense that it belongs to the class rather than a particular instance, you use the same syntax. The '&' is necessary because technically speaking you don't pass functions directly -- functions are not real objects in C++. Instead you're technically passing the memory address for the function, that is, a pointer to where the function's instructions begin in memory. The consequence is the same though, you're effectively 'passing a function' as a parameter.

But that's only half the problem in this instance. As I said, RedundencyManagerCallBack the function doesn't 'belong' to any particular instance. But it sounds like you want to pass it as a callback with a particular instance in mind. To understand how to do this you need to understand what member functions really are: regular not-defined-in-any-class functions with an extra hidden parameter.

For example:

class A {
public:
    A() : data(0) {}
    void foo(int addToData) { this->data += addToData; }

    int data;
};

...

A an_a_object;
an_a_object.foo(5);
A::foo(&an_a_object, 5); // This is the same as the line above!
std::cout << an_a_object.data; // Prints 10!

How many parameters does A::foo take? Normally we would say 1. But under the hood, foo really takes 2. Looking at A::foo's definition, it needs a specific instance of A in order for the 'this' pointer to be meaningful (the compiler needs to know what 'this' is). The way you usually specify what you want 'this' to be is through the syntax MyObject.MyMemberFunction(). But this is just syntactic sugar for passing the address of MyObject as the first parameter to MyMemberFunction. Similarly, when we declare member functions inside class definitions we don't put 'this' in the parameter list, but this is just a gift from the language designers to save typing. Instead you have to specify that a member function is static to opt out of it automatically getting the extra 'this' parameter. If the C++ compiler translated the above example to C code (the original C++ compiler actually worked that way), it would probably write something like this:

struct A {
    int data;
};

void a_init(A* to_init)
{
    to_init->data = 0;
}

void a_foo(A* this, int addToData)
{ 
    this->data += addToData;
}

...

A an_a_object;
a_init(0); // Before constructor call was implicit
a_foo(&an_a_object, 5); // Used to be an_a_object.foo(5);

Returning to your example, there is now an obvious problem. 'Init' wants a pointer to a function that takes one parameter. But &CLoggersInfra::RedundencyManagerCallBack is a pointer to a function that takes two parameters, it's normal parameter and the secret 'this' parameter. That's why you're still getting a compiler error (as a side note: If you've ever used Python, this kind of confusion is why a 'self' parameter is required for all member functions).

The verbose way to handle this is to create a special object that holds a pointer to the instance you want and has a member function called something like 'run' or 'execute' (or overloads the '()' operator) that takes the parameters for the member function, and simply calls the member function with those parameters on the stored instance. But this would require you to change 'Init' to take your special object rather than a raw function pointer, and it sounds like Init is someone else's code. And making a special class for every time this problem comes up will lead to code bloat.

So now, finally, the good solution, boost::bind and boost::function, the documentation for each you can find here:

boost::bind docs, boost::function docs

boost::bind will let you take a function, and a parameter to that function, and make a new function where that parameter is 'locked' in place. So if I have a function that adds two integers, I can use boost::bind to make a new function where one of the parameters is locked to say 5. This new function will only take one integer parameter, and will always add 5 specifically to it. Using this technique, you can 'lock in' the hidden 'this' parameter to be a particular class instance, and generate a new function that only takes one parameter, just like you want (note that the hidden parameter is always the first parameter, and the normal parameters come in order after it). Look at the boost::bind docs for examples, they even specifically discuss using it for member functions. Technically there is a standard function called [std::bind1st][3] that you could use as well, but boost::bind is more general.

Of course, there's just one more catch. boost::bind will make a nice boost::function for you, but this is still technically not a raw function pointer like Init probably wants. Thankfully, boost provides a way to convert boost::function's to raw pointers, as documented on StackOverflow here. How it implements this is beyond the scope of this answer, though it's interesting too.

Don't worry if this seems ludicrously hard -- your question intersects several of C++'s darker corners, and boost::bind is incredibly useful once you learn it.

C++11 update: Instead of boost::bind you can now use a lambda function that captures 'this'. This is basically having the compiler generate the same thing for you.

Encountered the same error in different use case.

Use Case: In chrome when tried to call Spring REST end point in angular.

Solution: Add @CrossOrigin("*") annotation on top of respective Controller Class.

you might consider using the Relative and Absolute positining.

`.container {  
position: relative;  
}  
.tag {     
position: absolute;   
}`  

I have tested it there, also if you want it to change its position use this as its margin:

top: 20px;
left: 10px;

It will place it 20 pixels from top and 10 pixels from left; but leave this one if not necessary.

Assuming that you are using UTF-8 encoding:

string convert = "This is the string to be converted";

// From string to byte array
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(convert);

// From byte array to string
string s = System.Text.Encoding.UTF8.GetString(buffer, 0, buffer.Length);

Using the InstallCert to generate the jssecacerts file and do -Djavax.net.ssl.trustStore=/path/to/jssecacerts worked great.

After adding this line of code, the issue will be fixed:

This is just a wrap up of Sayan Pal answer in a shorter form, ES5 style :

var Foo = function(){
    this.bar = undefined;
    this.buzz = undefined;
}

var foo = Object.assign(new Foo(),{
    bar: "whatever",
    buzz: "something else"
});

I like it because it is the closest to the very neat object initialisation in .Net:

var foo = new Foo()
{
    bar: "whatever",
    ...

string atest = "9586-202-10072";
int indexOfHyphen = atest.LastIndexOf("-");

if (indexOfHyphen >= 0)
{
    string contentAfterLastHyphen = atest.Substring(indexOfHyphen + 1);
    Console.WriteLine(contentAfterLastHyphen );
}

Note that besides all other comments there is a small difference, which should be mentioned here for completeness!

With the empty catch clause you can catch non-CLSCompliant Exceptions when the assembly is marked with "RuntimeCompatibility(WrapNonExceptionThrows = false)" (which is true by default since CLR2). [1][2][3]

return in function return execution back to caller and exit from function terminates the program.

in main function return 0 or exit(0) are same but if you write exit(0) in different function then you program will exit from that position.

returning different values like return 1 or return -1 means that program is returning error .

When exit(0) is used to exit from program, destructors for locally scoped non-static objects are not called. But destructors are called if return 0 is used.

Xml declaration is optional so your xml is well-formed without it. But it is recommended to use it so that wrong assumptions are not made by the parsers, specifically about the encoding used.

If you are using Python3 with pathlib you can access os.stat() information using the Path.stat() method, which has the attribute st_size(file size in bytes):

>>> from pathlib import Path 
>>> mypath = Path("path/to/my/file")
>>> mypath.stat().st_size == 0 # True if empty

This is very nice:

You can use the git config to enable credentials storage in git.

git config --global credential.helper store

When running this command, the first time you pull or push from the remote repository, you'll get asked about the username and password.

Afterwards, for consequent communications with the remote repository you don't have to provide the username and password.

The storage format is a .git-credentials file, stored in plaintext.

Also, you can use other helpers for the git config credential.helper, namely memory cache:

git config credential.helper cache <timeout>

which takes an optional timeout parameter, determining for how long the credentials will be kept in memory. Using the helper, the credentials will never touch the disk and will be erased after the specified timeout. The default value is 900 seconds (15 minutes).

WARNING : If you use this method, your git account passwords will be saved in plaintext format, in the global .gitconfig file, e.g in linux it will be /home/[username]/.gitconfig

If this is undesirable to you, use an ssh key for your accounts instead.

You guys are complicating things. You can simple do this from CSS.

#carousel li { background-position:0px 0px; }
#carousel li:hover { background-position:100px 0px; }

I am not sure of why you're adding the strings to files, which is declared as a field rather than a temporary variable. You could change the signature of DirSearch to:

private List<string> DirSearch(string sDir)

And, after the catch block, add:

return files;

Alternatively, you could create a temporary variable inside of your method and return it, which seems to me the approach you might desire. Otherwise, each time you call that method, the newly found strings will be added to the same list as before and you'll have duplicates.

This jsPerf test suggests that find() is faster. I created a more thorough test, and it still looks as though find() outperforms children().

Update: As per tvanfosson's comment, I created another test case with 16 levels of nesting. find() is only slower when finding all possible divs, but find() still outperforms children() when selecting the first level of divs.

children() begins to outperform find() when there are over 100 levels of nesting and around 4000+ divs for find() to traverse. It's a rudimentary test case, but I still think that find() is faster than children() in most cases.

I stepped through the jQuery code in Chrome Developer Tools and noticed that children() internally makes calls to sibling(), filter(), and goes through a few more regexes than find() does.

find() and children() fulfill different needs, but in the cases where find() and children() would output the same result, I would recommend using find().

"Session" is the term used to refer to a user's time browsing a web site. It's meant to represent the time between their first arrival at a page in the site until the time they stop using the site. In practice, it's impossible to know when the user is done with the site. In most servers there's a timeout that automatically ends a session unless another page is requested by the same user.

The first time a user connects some kind of session ID is created (how it's done depends on the web server software and the type of authentication/login you're using on the site). Like cookies, this usually doesn't get sent in the URL anymore because it's a security problem. Instead it's stored along with a bunch of other stuff that collectively is also referred to as the session. Session variables are like cookies - they're name-value pairs sent along with a request for a page, and returned with the page from the server - but their names are defined in a web standard.

Some session variables are passed as HTTP headers. They're passed back and forth behind the scenes of every page browse so they don't show up in the browser and tell everybody something that may be private. Among them are the USER_AGENT, or type of browser requesting the page, the REFERRER or the page that linked to the page being requested, etc. Some web server software adds their own headers or transfer additional session data specific to the server software. But the standard ones are pretty well documented.

Hope that helps.

• Remove the file from the index, but keep it versioned and left with uncommitted changes in working copy:

  git reset head <file>
  

• Reset the file to the last state from HEAD, undoing changes and removing them from the index:

  git reset HEAD <file>
  git checkout <file>
  
  # If you have a `<branch>` named like `<file>`, use:
  git checkout -- <file>
  

  This is needed since git reset --hard HEAD won't work with single files.

• Remove <file> from index and versioning, keeping the un-versioned file with changes in working copy:

  git rm --cached <file>
  

• Remove <file> from working copy and versioning completely:

  git rm <file>
  

Try changing it to.

 Response.Clear();
 Response.ClearHeaders();
 Response.ClearContent();

 Response.AddHeader("Content-Length", file.Length.ToString());
 Response.ContentType = "text/plain";
 Response.Flush();
 Response.TransmitFile(file.FullName);
 Response.End();

As I discovered having followed the advice in the answers given so far, you can get exceptions occuring without error messages being set, so to catch all problems you really need to get both the ErrorMessage and the Exception.

String messages = String.Join(Environment.NewLine, ModelState.Values.SelectMany(v => v.Errors)
                                                           .Select( v => v.ErrorMessage + " " + v.Exception));

or as an extension method

public static IEnumerable<String> GetErrors(this ModelStateDictionary modelState)
{
      return modelState.Values.SelectMany(v => v.Errors)
                              .Select( v => v.ErrorMessage + " " + v.Exception).ToList();

}

long timeadj = 24*60*60*1000;
Date newDate = new Date (oldDate.getTime ()+timeadj);

This takes the number of milliseconds since epoch from oldDate and adds 1 day worth of milliseconds then uses the Date() public constructor to create a date using the new value. This method allows you to add 1 day, or any number of hours/minutes, not only whole days.

Add below method in your activity class.Here browser is nothing but your webview object.

        browser.goBack();
        return true;

Validating that it is a real email address is much harder.

The regex to confirm the syntax is correct can be very long (see http://www.regular-expressions.info/email.html for example). The best way to confirm an email address is to email the user, and get the user to reply by clicking on a link to validate that they have recieved the email (the way most sign-up systems work).

alias_method new_method, old_method

old_method will be declared in a class or module which is being inherited now to our class where new_method will be used.

these can be variable or method both.

Suppose Class_1 has old_method, and Class_2 and Class_3 both of them inherit Class_1.

If, initialization of Class_2 and Class_3 is done in Class_1 then both can have different name in Class_2 and Class_3 and its usage.

Logical operators for boolean indexing in Pandas

It's important to realize that you cannot use any of the Python logical operators (and, or or not) on pandas.Series or pandas.DataFrames (similarly you cannot use them on numpy.arrays with more than one element). The reason why you cannot use those is because they implicitly call bool on their operands which throws an Exception because these data structures decided that the boolean of an array is ambiguous:

>>> import numpy as np
>>> import pandas as pd
>>> arr = np.array([1,2,3])
>>> s = pd.Series([1,2,3])
>>> df = pd.DataFrame([1,2,3])
>>> bool(arr)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
>>> bool(s)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> bool(df)
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

I did cover this more extensively in my answer to the "Truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()" Q+A.

NumPys logical functions

However NumPy provides element-wise operating equivalents to these operators as functions that can be used on numpy.array, pandas.Series, pandas.DataFrame, or any other (conforming) numpy.array subclass:

• and has np.logical_and
• or has np.logical_or
• not has np.logical_not
• numpy.logical_xor which has no Python equivalent but is a logical "exclusive or" operation

So, essentially, one should use (assuming df1 and df2 are pandas DataFrames):

np.logical_and(df1, df2)
np.logical_or(df1, df2)
np.logical_not(df1)
np.logical_xor(df1, df2)

Bitwise functions and bitwise operators for booleans

However in case you have boolean NumPy array, pandas Series, or pandas DataFrames you could also use the element-wise bitwise functions (for booleans they are - or at least should be - indistinguishable from the logical functions):

• bitwise and: np.bitwise_and or the & operator
• bitwise or: np.bitwise_or or the | operator
• bitwise not: np.invert (or the alias np.bitwise_not) or the ~ operator
• bitwise xor: np.bitwise_xor or the ^ operator

Typically the operators are used. However when combined with comparison operators one has to remember to wrap the comparison in parenthesis because the bitwise operators have a higher precedence than the comparison operators:

(df1 < 10) | (df2 > 10)  # instead of the wrong df1 < 10 | df2 > 10

This may be irritating because the Python logical operators have a lower precendence than the comparison operators so you normally write a < 10 and b > 10 (where a and b are for example simple integers) and don't need the parenthesis.

Differences between logical and bitwise operations (on non-booleans)

It is really important to stress that bit and logical operations are only equivalent for boolean NumPy arrays (and boolean Series & DataFrames). If these don't contain booleans then the operations will give different results. I'll include examples using NumPy arrays but the results will be similar for the pandas data structures:

>>> import numpy as np
>>> a1 = np.array([0, 0, 1, 1])
>>> a2 = np.array([0, 1, 0, 1])

>>> np.logical_and(a1, a2)
array([False, False, False,  True])
>>> np.bitwise_and(a1, a2)
array([0, 0, 0, 1], dtype=int32)

And since NumPy (and similarly pandas) does different things for boolean (Boolean or “mask” index arrays) and integer (Index arrays) indices the results of indexing will be also be different:

>>> a3 = np.array([1, 2, 3, 4])

>>> a3[np.logical_and(a1, a2)]
array([4])
>>> a3[np.bitwise_and(a1, a2)]
array([1, 1, 1, 2])

Summary table

Logical operator | NumPy logical function | NumPy bitwise function | Bitwise operator
-------------------------------------------------------------------------------------
       and       |  np.logical_and        | np.bitwise_and         |        &
-------------------------------------------------------------------------------------
       or        |  np.logical_or         | np.bitwise_or          |        |
-------------------------------------------------------------------------------------
                 |  np.logical_xor        | np.bitwise_xor         |        ^
-------------------------------------------------------------------------------------
       not       |  np.logical_not        | np.invert              |        ~

Where the logical operator does not work for NumPy arrays, pandas Series, and pandas DataFrames. The others work on these data structures (and plain Python objects) and work element-wise. However be careful with the bitwise invert on plain Python bools because the bool will be interpreted as integers in this context (for example ~False returns -1 and ~True returns -2).

I don't know of anyway to put a condition in the format specifier, but you can write your own formatter:

bmleite has the correct answer about including the module.

If that is correct in your situation, you should also ensure that you are not redefining the modules in multiple files.

Remember:

angular.module('ModuleName', [])   // creates a module.

angular.module('ModuleName')       // gets you a pre-existing module.

So if you are extending a existing module, remember not to overwrite when trying to fetch it.

as of the django development, there exists bulk_create as an object manager method which takes as input an array of objects created using the class constructor. check out django docs

Here's another option, which is less efficient but more concise. It's how I generally handle this sort of problem:

Get-ChildItem -Recurse .\targetdir -Exclude *.log |
  Where-Object { $_.FullName -notmatch '\\excludedir($|\\)' }

The \\excludedir($|\\)' expression allows you to exclude the directory and its contents at the same time.

Update: Please check the excellent answer from msorens for an edge case flaw with this approach, and a much more fleshed out solution overall.

Yes Jython does this, but it may or may not be what you want

I believe that I found the correct answer through this dig How To. I was able to look up the SPF records on a specific DNS, by using the following query:

dig @ns1.nameserver1.com domain.com txt

The integer passed to the constructor represents its initial capacity, i.e., the number of elements it can hold before it needs to resize its internal array (and has nothing to do with the initial number of elements in the list).

To initialize an list with 60 zeros you do:

List<Integer> list = new ArrayList<Integer>(Collections.nCopies(60, 0));

If you want to create a list with 60 different objects, you could use the Stream API with a Supplier as follows:

List<Person> persons = Stream.generate(Person::new)
                             .limit(60)
                             .collect(Collectors.toList());

In my case,

sudo chmod ug+wx .git -R

this command works.

Summary (@Freek Wiekmeijer, @gtalarico) other's answer:

Logic of Login

• Many resource(pages, api) need authentication, then can access, otherwise 405 Not Allowed
• Common authentication=grant access method are:
  • cookie
  • auth header
    • Basic xxx
    • Authorization xxx

How use cookie in requests to auth

1. first get/generate cookie
2. send cookie for following request

• manual set cookie in headers
• auto process cookie by requests's
  • session to auto manage cookies
  • response.cookies to manually set cookies

use requests's session auto manage cookies

curSession = requests.Session() 
# all cookies received will be stored in the session object

payload={'username': "yourName",'password': "yourPassword"}
curSession.post(firstUrl, data=payload)
# internally return your expected cookies, can use for following auth

# internally use previously generated cookies, can access the resources
curSession.get(secondUrl)

curSession.get(thirdUrl)

manually control requests's response.cookies

payload={'username': "yourName",'password': "yourPassword"}
resp1 = requests.post(firstUrl, data=payload)

# manually pass previously returned cookies into following request
resp2 = requests.get(secondUrl, cookies= resp1.cookies)

resp3 = requests.get(thirdUrl, cookies= resp2.cookies)

try this

using System.Drawing;
driver.Manage().Window.Size = new Size(width, height);

Long story short you have to use atoi()

ed:

If you are interested in doing this the right way :

char szNos[] = "12345";
char *pNext;
long output;
output = strtol (szNos, &pNext, 10); // input, ptr to next char in szNos (null here), base 

The feature is called "code templates" in Eclipse. You can add templates with:

Window->Preferences->Java->Editor->Templates.

Two good articles:

• Don't write the code, generate it
• Custom Templates

Also, this SO question:

• Useful Eclipse Java Code Templates

System.out.println() is already mapped to sysout, so you may save time by learning a few of the existing templates first.

I think that what you have to check is:

1. if the target EXE is correctly configured in the project settings ("command", in the debugging tab). Since all individual projects run when you start debugging it's well possible that only the debugging target for the "ALL" solution is missing, check which project is currently active (you can also select the debugger target by changing the active project).

2. dependencies (DLLs) are also located at the target debugee directory or can be loaded (you can use the "depends.exe" tool for checking dependencies of an executable or DLL).

One other significant point if you're using C# 6:

'=>' can be used instead of 'get' and is only for 'get only' methods - it can't be used with a 'set'.

For C# 7, see the comment from @avenmore below - it can now be used in more places. Here's a good reference - https://csharp.christiannagel.com/2017/01/25/expressionbodiedmembers/

I landed here because of an XCTestCase, in which I'd disabled most of the tests by prefixing them with 'no_' as in no_testBackgroundAdding. Once I noticed that most of the answers had something to do with locks and threading, I realized the test contained a few instances of XCTestExpectation with corresponding waitForExpectations. They were all in the disabled tests, but apparently Xcode was still evaluating them at some level.

In the end I found an XCTestExpectation that was defined as @property but lacked the @synthesize. Once I added the synthesize directive, the EXC_BAD_INSTRUCTION disappeared.

Try this:

CSS:

.hidden{display:none;}

HTML:

<table id="table" class="hidden">
    <tr>
        <th>City</th>
        <th>Status</th>
    </tr>
</table>

JS:

$('#search').click(function() {
    $.ajax({
        type: 'POST',
        url: 'cityResults.htm',
        data: $('#cityDetails').serialize(),
        dataType:"json", //to parse string into JSON object,
        success: function(data){ 
            if(data){
                var len = data.length;
                var txt = "";
                if(len > 0){
                    for(var i=0;i<len;i++){
                        if(data[i].city && data[i].cStatus){
                            txt += "<tr><td>"+data[i].city+"</td><td>"+data[i].cStatus+"</td></tr>";
                        }
                    }
                    if(txt != ""){
                        $("#table").append(txt).removeClass("hidden");
                    }
                }
            }
        },
        error: function(jqXHR, textStatus, errorThrown){
            alert('error: ' + textStatus + ': ' + errorThrown);
        }
    });
    return false;//suppress natural form submission
});

So I had this issue with Adobe Reader 9.0. Somehow the program forgot to open on my right monitor and was consistently opening on my left monitor. Most programs allow you to drag it over, maximize the screen, and then close it out and it will remember. Well, with Adobe, I had to drag it over and then close it before maximizing it, in order for Windows to remember which screen to open it in next time. Once you set it to the correct monitor, then you can maximize it. I think this is stupid, since almost all windows programs remember it automatically without try to rig a way for XP to remember.

Perhaps mathJAX is the ticket. It's built on jsMath, a 2004 vintage JavaScript library.

As of 5-Feb-2015 I'd switch to recommend KaTeX - most performant Javascript LaTeX library from Khan Academy.

When using a string-typed variable in PHP containing a date, the variable must be enclosed in single quotes:

$NEW_DATE = '1997-07-15';
$sql = "INSERT INTO tbl (NEW_DATE, ...) VALUES ('$NEW_DATE', ...)";

Check this Link it contains a java-script code that you can use to refresh your page only once

http://www.hotscripts.com/forums/javascript/4460-how-do-i-have-page-automatically-refesh-only-once.html

There are more than one way to refresh your page:

solution1:

To refresh a page once each time it opens use:

<head>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
</head>

sollution2:

<script language=" JavaScript" >
<!-- 
function LoadOnce() 
{ 
window.location.reload(); 
} 
//-->
</script>

Then change your to say

<Body onLoad=" LoadOnce()" >

solution3:

response.setIntHeader("Refresh", 1);

But this solution will refresh the page more than one time depend on the time you specifying

I hope that will help you

If you want to do that yourself, without using any external library, a clean way would be to create a template.html file with all the static content, like for example:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>$title</title>
</head>
<body>$body
</body>
</html>

Put a tag like $tag for any dynamic content and then do something like this:

File htmlTemplateFile = new File("path/template.html");
String htmlString = FileUtils.readFileToString(htmlTemplateFile);
String title = "New Page";
String body = "This is Body";
htmlString = htmlString.replace("$title", title);
htmlString = htmlString.replace("$body", body);
File newHtmlFile = new File("path/new.html");
FileUtils.writeStringToFile(newHtmlFile, htmlString);

Note: I used org.apache.commons.io.FileUtils for simplicity.

In rails 4.2 the above methods didn't work.

1. Go to the Terminal.
2. Change the directory to the location where your rake file is present.
3. run rake task_name.
4. In the above case, run rake iqmedier - will run only iqmedir task.
5. run rake euroads - will run only the euroads task.

6. To Run all the tasks in that file assign the following inside the same file and run rake all

   task :all => [:iqmedier, :euroads, :mikkelsen, :orville ] do #This will print all the tasks o/p on the screen 
   end
   

Why this happens?

The default is to return the original, unaltered document. If you want the new, updated document to be returned you have to pass an additional argument: an object with the new property set to true.

From the mongoose docs:

Query#findOneAndUpdate

Model.findOneAndUpdate(conditions, update, options, (error, doc) => {
  // error: any errors that occurred
  // doc: the document before updates are applied if `new: false`, or after updates if `new = true`
});

Available options

• new: bool - if true, return the modified document rather than the original. defaults to false (changed in 4.0)

Solution

Pass {new: true} if you want the updated result in the doc variable:

//                                                         V--- THIS WAS ADDED
Cat.findOneAndUpdate({age: 17}, {$set:{name:"Naomi"}}, {new: true}, (err, doc) => {
    if (err) {
        console.log("Something wrong when updating data!");
    }

    console.log(doc);
});

@foxxtrot

Actually, the standard shell is Bourne shell (sh). /bin/sh on Linux is actually bash, but if you're aiming for cross-platform scripts, you're better off sticking to features of the original Bourne shell or writing it in something like perl.

The error MethodNotAllowedHttpException means the route exists, but the HTTP method (GET) is wrong. You have to change it to POST:

Route::post('test/register', array('uses'=>'TestController@create'));

Also, you need to hash your passwords:

public function create()
{
    $user = new User;

    $user->username = Input::get('username');
    $user->email = Input::get('email');
    $user->password = Hash::make(Input::get('password'));
    $user->save();

    return Redirect::back();
}

And I removed the line:

$user= Input::all();

Because in the next command you replace its contents with

$user = new User;

To debug your Input, you can, in the first line of your controller:

dd( Input::all() );

It will display all fields in the input.

Update - the answer below was written before C# 6 came along. In C# 6 you can write:

public class Foo
{
    public string Bar { get; set; } = "bar";
}

You can also write read-only automatically-implemented properties, which are only writable in the constructor (but can also be given a default initial value):

public class Foo
{
    public string Bar { get; }

    public Foo(string bar)
    {
        Bar = bar;
    }
}

It's unfortunate that there's no way of doing this right now. You have to set the value in the constructor. (Using constructor chaining can help to avoid duplication.)

Automatically implemented properties are handy right now, but could certainly be nicer. I don't find myself wanting this sort of initialization as often as a read-only automatically implemented property which could only be set in the constructor and would be backed by a read-only field.

This hasn't happened up until and including C# 5, but is being planned for C# 6 - both in terms of allowing initialization at the point of declaration, and allowing for read-only automatically implemented properties to be initialized in a constructor body.

This appear to be default behaviour now, so it's enough to do:

$("#press-enter").on("click", function(){alert("You `clicked' or 'Entered' me!")})

You can try it in this JSFiddle

Tested on: Chrome 56.0 and Firefox (Dev Edition) 54.0a2, both with jQuery 2.2.x and 3.x

Full disclosure, I am one of the maintainers of pdfminer.six.

Nowadays, there are multiple api's to extract text from a PDF, depending on your needs. Behind the scenes, all of these api's use the same logic for parsing and analyzing the layout.

(All the examples assume your PDF file is called example.pdf)

Commandline

If you want to extract text just once you can use the commandline tool pdf2txt.py:

$ pdf2txt.py example.pdf

High-level api

If you want to extract text with Python, you can use the high-level api. This approach is the go-to solution if you want to extract text programmatically from many PDF's.

from pdfminer.high_level import extract_text

text = extract_text('example.pdf')

Composable api

There is also a composable api that gives a lot of flexibility in handling the resulting objects. For example, you can implement your own layout algorithm using that. This method is suggested in the other answers, but I would only recommend this when you need to customize the way pdfminer.six behaves.

from io import StringIO

from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.pdfparser import PDFParser

output_string = StringIO()
with open('example.pdf', 'rb') as in_file:
    parser = PDFParser(in_file)
    doc = PDFDocument(parser)
    rsrcmgr = PDFResourceManager()
    device = TextConverter(rsrcmgr, output_string, laparams=LAParams())
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    for page in PDFPage.create_pages(doc):
        interpreter.process_page(page)

print(output_string.getvalue())

try something like this:

a = buffer[3];
a = a*256 + buffer[2];
a = a*256 + buffer[1];
a = a*256 + buffer[0];

this is assuming that the lowest byte comes first. if the highest byte comes first you might have to swap the indices (go from 0 to 3).

basically for each byte you want to add, you first multiply a by 256 (which equals a shift to the left by 8 bits) and then add the new byte.

The easiest and the most correct (and legal) way is to use graph api.

Just perform the request: http://graph.facebook.com/4

which returns

{
   "id": "4",
   "name": "Mark Zuckerberg",
   "first_name": "Mark",
   "last_name": "Zuckerberg",
   "link": "http://www.facebook.com/zuck",
   "username": "zuck",
   "gender": "male",
   "locale": "en_US"
}

and take the link key.

You can also reduce the traffic by using fields parameter: http://graph.facebook.com/4?fields=link to get only what you need:

{
   "link": "http://www.facebook.com/zuck",
   "id": "4"
}

We had nearly this exact same issue occur recently and it turned out to be caused by Microsoft update KB980436 (http://support.microsoft.com/KB/980436) being installed on the calling computer. The fix for us, other than uninstalling it outright, was to follow the instructions at the KB site for setting the UseScsvForTls DWORD in the registry to 1. If you see this update is installed in your calling system you may want to give it a shot.

I think this is the most convenient if you just want to see the content in the list:

myList = ['foo', 'bar']
print('myList is %s' % str(myList))

Simple, easy to read and can be used together with format string.

I was having the same problem. To fix it I added the following headers:

Content-Type: application/json

I had to manually add the content type even though I also had the type of "json" in the raw post field parameters.

Why not use window's own onload event ?

window.onload = function () {
      alert("LOADED!");
}

If I'm not mistaken, that is compatible across all browsers.

Another way, you can use a pass-through object to capture the last value and then do something with it:

List<Integer> list = new ArrayList<Integer>();
Integer lastValue = null;
for (Integer i : list) {
    // do stuff
    lastValue = i;
}
// do stuff with last value

I miss an other Solution here (2021): I use FileList to interact with file input.

Since there is no way to create a FileList object, I use DataTransfer, that brings clean FilleList with it.

I reset it with:

  file_input.files=new DataTransfer().files  

In my case this perfectly fits, since I interact only via FileList with my encapsulated file input element.

This will open the link in a new tab in Chrome and Firefox, and possibly more browsers I haven't tested:

var popup  = $window.open("about:blank", "_blank"); // the about:blank is to please Chrome, and _blank to please Firefox
popup.location = 'newpage.html';

It basically opens a new empty tab, and then sets the location of that empty tab. Beware that it is a sort of a hack, since browser tab/window behavior is really the domain, responsibility and choice of the Browser and the User.

The second line can be called in a callback (after you've done some AJAX request for example), but then the browser would not recognize it as a user-initiated click-event, and may block the popup.

Label without an onclick will behave as you would expect. It changes the input. What you relly want is to execute selectAll() when you click on a label, right? Then only add select all to the label onclick. Or wrap the input into the the label and assign onclick only for the label

<label for="check_all_1" onclick="selectAll(document.wizard_form, this);">
  <input type="checkbox" id="check_all_1" name="check_all_1" title="Select All">
  Select All
</label>

If the solutions proposed here aren't working for you, and your image asset is actually a PDF, note that XCode actually treats PDFs differently than image files. In particular, it doesn't seem able to scale to fill properly with a PDF: it ends up tiled instead. This drove me crazy until I figured out that the issue was the PDF format. Convert to JPG and you should be good to go.

This seems to be a bug in the newly added support for nested fragments. Basically, the child FragmentManager ends up with a broken internal state when it is detached from the activity. A short-term workaround that fixed it for me is to add the following to onDetach() of every Fragment which you call getChildFragmentManager() on:

@Override
public void onDetach() {
    super.onDetach();

    try {
        Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
        childFragmentManager.setAccessible(true);
        childFragmentManager.set(this, null);

    } catch (NoSuchFieldException e) {
        throw new RuntimeException(e);
    } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    }
}

You can use it without casting such as:

select sum(`stuff`) as mySum from test;

Or cast it to decimal:

select sum(cast(`stuff` as decimal(4,2))) as mySum from test;

SQLFiddle

EDIT

For SQL Server, you can use:

select sum(cast(stuff as decimal(5,2))) as mySum from test;

SQLFiddle

String[] splitArray = subjectString.split("\\|\\|");

You use a function:

public String[] stringSplit(String string){

    String[] splitArray = string.split("\\|\\|");
    return splitArray;
}

Screams in to the void - just "no" don't do it. This is a dumb idea.

Integrating with external data sources is what SSIS is for, or write a dot net application/service which queries the box and makes the API calls.

Writing CLR code to enable a SQL process to call web-services is the sort of thing that can bring a SQL box to its knees if done badly - imagine putting the the CLR function in a view somewhere - later someone else comes along not knowing what you've donem and joins on that view with a million row table - suddenly your SQL box is making a million individual webapi calls.

The whole idea is insane.

This doing sort of thing is the reason that enterprise DBAs dont' trust developers.

CLR is the kind of great power, which brings great responsibility, and the above is an abuse of it.

Set a width on the form element (which should exist in your example! ) and float (and clear) the input elements. Also, drop the br elements.

Find this example in one book, and think it's quite elegant solution.

 static void Main(string[] args)
    {
        Console.Write("Enter a number: ");
        int theNum = int.Parse(Console.ReadLine());

        if (theNum < 3)  // special case check, less than 3
        {
            if (theNum == 2)
            {
                // The only positive number that is a prime
                Console.WriteLine("{0} is a prime!", theNum);
            }
            else
            {
                // All others, including 1 and all negative numbers, 
                // are not primes
                Console.WriteLine("{0} is not a prime", theNum);
            }
        }
        else
        {
            if (theNum % 2 == 0)
            {
                // Is the number even?  If yes it cannot be a prime
                Console.WriteLine("{0} is not a prime", theNum);
            }
            else
            {
                // If number is odd, it could be a prime
                int div;

                // This loop starts and 3 and does a modulo operation on all
                // numbers.  As soon as there is no remainder, the loop stops.
                // This can be true under only two circumstances:  The value of
                // div becomes equal to theNum, or theNum is divided evenly by 
                // another value.
                for (div = 3; theNum % div != 0; div += 2)
                    ;  // do nothing

                if (div == theNum)
                {
                    // if theNum and div are equal it must be a prime
                    Console.WriteLine("{0} is a prime!", theNum);
                }
                else
                {
                    // some other number divided evenly into theNum, and it is not
                    // itself, so it is not a prime
                    Console.WriteLine("{0} is not a prime", theNum);
                }
            }
        }

        Console.ReadLine();
    }

I know you asked for non-looping solutions, but the only solutions I can come up with probably loop internally anyway:

map(int,y)

or:

[i*1 for i in y]

or:

import numpy
y=numpy.array(y)
y*1

Try using below:

SELECT 
    (RTRIM(LTRIM(col_1))) + (RTRIM(LTRIM(col_2))) AS Col_newname,
    col_1,
    col_2 
FROM 
    s_cols 
WHERE
    col_any_condition = ''
;

model =list.stream().max(Comparator.comparing(Model::yourSortList)).get();

Since you're comparing numbers, you can use an arithmetic expression, which allows for simpler handling of parameters and comparison:

wget -q --tries=10 --timeout=20 --spider http://google.com
if (( $? != 0 )); then
    echo "Sorry you are Offline"
    exit 1
fi

Notice how instead of -ne, you can just use !=. In an arithmetic context, we don't even have to prepend $ to parameters, i.e.,

var_a=1
var_b=2
(( var_a < var_b )) && echo "a is smaller"

works perfectly fine. This doesn't appply to the $? special parameter, though.

Further, since (( ... )) evaluates non-zero values to true, i.e., has a return status of 0 for non-zero values and a return status of 1 otherwise, we could shorten to

if (( $? )); then

but this might confuse more people than the keystrokes saved are worth.

The (( ... )) construct is available in Bash, but not required by the POSIX shell specification (mentioned as possible extension, though).

This all being said, it's better to avoid $? altogether in my opinion, as in Cole's answer and Steven's answer.

As Python newbie learning the Python ecosystem I've just completed this.

1. Install setuptools instructions

2. Install MySQL 5.1. Download the 97.6MB MSI from here You can't use the essentials version because it doesnt contain the C libraries.
   Be sure to select a custom install, and mark the development tools / libraries for installation as that is not done by default. This is needed to get the C header files.
   You can verify you have done this correctly by looking in your install directory for a folder named "include". E.G C:\Program Files\MySQL\MySQL Server 5.1\include. It should have a whole bunch of .h files.

3. Install Microsoft Visual Studio C++ Express 2008 from here This is needed to get a C compiler.

4. Open up a command line as administrator (right click on the Cmd shortcut and then "run as administrator". Be sure to open a fresh window after you have installed those things or your path won't be updated and the install will still fail.

5. From the command prompt:

   easy_install -b C:\temp\sometempdir mysql-python

   That will fail - which is OK.

   Now open site.cfg in your temp directory C:\temp\sometempdir and edit the "registry_key" setting to:

   registry_key = SOFTWARE\MySQL AB\MySQL Server 5.1

   now CD into your temp dir and:

   python setup.py clean

   python setup.py install

   You should be ready to rock!

6. Here is a super simple script to start off learning the Python DB API for you - if you need it.

This technique that John recommends is not recommended as there is no guarantee that the database will attach without the log file. Change the database from full to simple, force a checkpoint and wait a few minutes. The SQL Server will clear the log, which you can then shrink using DBCC SHRINKFILE.

function sendAjaxRequest(element,urlToSend) {
             var clickedButton = element;
              $.ajax({type: "POST",
                  url: urlToSend,
                  data: { id: clickedButton.val(), access_token: $("#access_token").val() },
                  success:function(result){
                    alert('ok');
                  },
                 error:function(result)
                  {
                  alert('error');
                 }
             });
     }

       $(document).ready(function(){
          $("#button_1").click(function(e){
              e.preventDefault();
              sendAjaxRequest($(this),'/pages/test/');
          });

          $("#button_2").click(function(e){
              e.preventDefault();
              sendAjaxRequest($(this),'/pages/test/');
          });
        });

1. created as separate function for sending the ajax request.
2. Kept second parameter as URL because in future you want to send data to different URL

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

I had the same issue when I first tried on node js.
I noticed this issue was happening to me because I had some .js files with same names in different directories, which were in the same main directory.
I created another directory outside the main project folder, and created a .js file.
After that, it ran fine.
ex- app.js

You can use QString.arg like this

QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", "Jane");
// You get "~/Tom-Jane.txt"

This method is preferred over sprintf because:

Changing the position of the string without having to change the ordering of substitution, e.g.

// To get "~/Jane-Tom.txt"
QString my_formatted_string = QString("%1/%3-%2.txt").arg("~", "Tom", "Jane");

Or, changing the type of the arguments doesn't require changing the format string, e.g.

// To get "~/Tom-1.txt"
QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", QString::number(1));

As you can see, the change is minimal. Of course, you generally do not need to care about the type that is passed into QString::arg() since most types are correctly overloaded.

One drawback though: QString::arg() doesn't handle std::string. You will need to call: QString::fromStdString() on your std::string to make it into a QString before passing it to QString::arg(). Try to separate the classes that use QString from the classes that use std::string. Or if you can, switch to QString altogether.

There are many great answers above so I just wanna add one more example in the case that you want to specify the exact number of samples for the train and test sets by using just the numpy library.

# set the random seed for the reproducibility
np.random.seed(17)

# e.g. number of samples for the training set is 1000
n_train = 1000

# shuffle the indexes
shuffled_indexes = np.arange(len(data_df))
np.random.shuffle(shuffled_indexes)

# use 'n_train' samples for training and the rest for testing
train_ids = shuffled_indexes[:n_train]
test_ids = shuffled_indexes[n_train:]

train_data = data_df.iloc[train_ids]
train_labels = labels_df.iloc[train_ids]

test_data = data_df.iloc[test_ids]
test_labels = data_df.iloc[test_ids]

Your calculation is correct for DATE types, but if your values are timestamps, you should probably use EXTRACT (or DATE_PART) to be sure to get only the difference in full days;

EXTRACT(DAY FROM MAX(joindate)-MIN(joindate)) AS DateDifference

An SQLfiddle to test with. Note the timestamp difference being 1 second less than 2 full days.
