You can't extend Enum as it's a static class. You can only extend instances of a type. With this in mind, you're going to have to create a static method yourself to do this; the following should work when combined with your existing method GetDescription:

public static class EnumHelper
{
    public static T GetEnumFromString<T>(string value)
    {
        if (Enum.IsDefined(typeof(T), value))
        {
            return (T)Enum.Parse(typeof(T), value, true);
        }
        else
        {
            string[] enumNames = Enum.GetNames(typeof(T));
            foreach (string enumName in enumNames)
            {  
                object e = Enum.Parse(typeof(T), enumName);
                if (value == GetDescription((Enum)e))
                {
                    return (T)e;
                }
            }
        }
        throw new ArgumentException("The value '" + value 
            + "' does not match a valid enum name or description.");
    }
}

And the usage of it would be something like this:

Animal giantPanda = EnumHelper.GetEnumFromString<Animal>("Giant Panda");

Update

The Unconstrained Melody library is no longer maintained; Support was dropped in favour of Enums.NET.

In Enums.NET you'd use:

string description = ((MyEnum)value).AsString(EnumFormat.Description);

Original post

I implemented this in a generic, type-safe way in Unconstrained Melody - you'd use:

string description = Enums.GetDescription((MyEnum)value);

This:

• Ensures (with generic type constraints) that the value really is an enum value
• Avoids the boxing in your current solution
• Caches all the descriptions to avoid using reflection on every call
• Has a bunch of other methods, including the ability to parse the value from the description

I realise the core answer was just the cast from an int to MyEnum, but if you're doing a lot of enum work it's worth thinking about using Unconstrained Melody :)

Here is yet another way to accomplish the task of associating strings with enums:

struct DATABASE {
    public enum enums {NOTCONNECTED, CONNECTED, ERROR}
    static List<string> strings =
        new List<string>() {"Not Connected", "Connected", "Error"};

    public string GetString(DATABASE.enums value) {
        return strings[(int)value];
    }
}

This method is called like this:

public FormMain() {
    DATABASE dbEnum;

    string enumName = dbEnum.GetString(DATABASE.enums.NOTCONNECTED);
}

You can group related enums in their own struct. Since this method uses the enum type, you can use Intellisense to display the list of enums when making the GetString() call.

You can optionally use the new operator on the DATABASE struct. Not using it means the strings List is not allocated until the first GetString() call is made.

If you're running on a Mac you could just search for Install Certificates.command on the spotlight and hit enter.

If you are inserting into a single table, you can write your query like this (maybe only in MySQL):

INSERT INTO table1 (First, Last)
VALUES
    ('Fred', 'Smith'),
    ('John', 'Smith'),
    ('Michael', 'Smith'),
    ('Robert', 'Smith');

A "method" is a "subroutine" is a "procedure" is a "function" is a "subprogram" is a ... The same concept goes under many different names, but basically is a named segment of code that you can "call" from some other code. Generally the code is neatly packaged somehow, with a "header" of some sort which gives its name and parameters and a "body" set off by BEGIN & END or { & } or some such.

A "consrtructor" is a special form of method whose purpose is to initialize an instance of a class or structure.

In Java a method's header is <qualifiers> <return type> <method name> ( <parameter type 1> <parameter name 1>, <parameter type 2> <parameter name 2>, ...) <exceptions> and a method body is bracketed by {}.

And you can tell a constructor from other methods because the constructor has the class name for its <method name> and has no declared <return type>.

(In Java, of course, you create a new class instance with the new operator -- new <class name> ( <parameter list> ).)

In JPA 2.0 if you want to delete an address if you removed it from a User entity you can add orphanRemoval=true (instead of CascadeType.REMOVE) to your @OneToMany.

More explanation between orphanRemoval=true and CascadeType.REMOVE is here.

In PostgreSQL 9.4 to create to file CSV with the header in Ubuntu:

COPY (SELECT * FROM tbl) TO '/home/user/Desktop/result_sql.csv' WITH CSV HEADER;

Note: The folder must be writable.

Add this to your package.json , “dependency”

"bootstrap": "^3.3.7",

In .angular-cli.json file, to your “Styles” add

"../node_modules/bootstrap/dist/css/bootstrap.css"

update your npm by using this command

npm update

You can use this jQuery function

function makePostRequest(url, data) {
    var jForm = $('<form></form>');
    jForm.attr('action', url);
    jForm.attr('method', 'post');
    for (name in data) {
        var jInput = $("<input>");
        jInput.attr('name', name);
        jInput.attr('value', data[name]);
        jForm.append(jInput);
    }
    jForm.submit();
}

Here is an example in jsFiddle (http://jsfiddle.net/S7zUm/)

git-bash uses standard unix commands.

ls for directory listing cd for change directory

As described in the documentation, by default it takes the color set in styles.xml attribute colorAccent.

The background color of this view defaults to the your theme's colorAccent. If you wish to change this at runtime then you can do so via setBackgroundTintList(ColorStateList).

If you wish to change the color

• in XML with attribute app:backgroundTint

<android.support.design.widget.FloatingActionButton
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_add"
    app:backgroundTint="@color/orange"
    app:borderWidth="0dp"
    app:elevation="6dp"
    app:fabSize="normal" >

• in code with .setBackgroundTintList (answer below by ywwynm)

As @Dantalian mentioned in the comments, if you wish to change the icon color for Design Support Library up to v22 (inclusive), you can use

android:tint="@color/white"     

For Design Support Library since v23 for you can use:

app:tint="@color/white"   

Also with androidX libraries you need to set a 0dp border in your xml layout:

<com.google.android.material.floatingactionbutton.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_add"
    app:backgroundTint="@color/orange"
    app:borderWidth="0dp"
    app:elevation="6dp"
    app:fabSize="normal" />

How about Freebase? I think they have an API available, too.

Something to extend print function for loops

x = 0
while x <=5:
    x = x + 1
    with open('outputEis.txt', 'a') as f:
        print(x, file=f)
    f.close()

I've came across this 'problem' as well but found a rather logical solution by adding the name attribute. I couldn't recall having this problem in other languages.

http://www.w3.org/TR/html401/interact/forms.html#h-17.13.2

• ...
• If a form contains more than one submit button, only the activated submit button is successful.
• ...

Meaning the following code value attributes can be changed, localized, internationalized without the need for extra code checking strongly-typed resources files or constants.

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="send" value="Send" />
<input type="submit" name="cancel" value="Cancel" />
<input type="submit" name="draft" value="Save as draft" />
<% Html.EndForm(); %>`

On the receiving end you would only need to check if any of your known submit types isn't null

public ActionResult YourAction(YourModel model) {

    if(Request["send"] != null) {

        // we got a send

    }else if(Request["cancel"]) {

        // we got a cancel, but would you really want to post data for this?

    }else if(Request["draft"]) {

        // we got a draft

    }

}

If your Python datetime object is timezone-aware than you should be careful to avoid errors around DST transitions (or changes in UTC offset for other reasons):

from datetime import datetime, timedelta
from tzlocal import get_localzone # pip install tzlocal

DAY = timedelta(1)
local_tz = get_localzone()   # get local timezone
now = datetime.now(local_tz) # get timezone-aware datetime object
day_ago = local_tz.normalize(now - DAY) # exactly 24 hours ago, time may differ
naive = now.replace(tzinfo=None) - DAY # same time
yesterday = local_tz.localize(naive, is_dst=None) # but elapsed hours may differ

In general, day_ago and yesterday may differ if UTC offset for the local timezone has changed in the last day.

For example, daylight saving time/summer time ends on Sun 2-Nov-2014 at 02:00:00 A.M. in America/Los_Angeles timezone therefore if:

import pytz # pip install pytz

local_tz = pytz.timezone('America/Los_Angeles')
now = local_tz.localize(datetime(2014, 11, 2, 10), is_dst=None)
# 2014-11-02 10:00:00 PST-0800

then day_ago and yesterday differ:

• day_ago is exactly 24 hours ago (relative to now) but at 11 am, not at 10 am as now
• yesterday is yesterday at 10 am but it is 25 hours ago (relative to now), not 24 hours.

pendulum module handles it automatically:

>>> import pendulum  # $ pip install pendulum

>>> now = pendulum.create(2014, 11, 2, 10, tz='America/Los_Angeles')
>>> day_ago = now.subtract(hours=24)  # exactly 24 hours ago
>>> yesterday = now.subtract(days=1)  # yesterday at 10 am but it is 25 hours ago

>>> (now - day_ago).in_hours()
24
>>> (now - yesterday).in_hours()
25

>>> now
<Pendulum [2014-11-02T10:00:00-08:00]>
>>> day_ago
<Pendulum [2014-11-01T11:00:00-07:00]>
>>> yesterday
<Pendulum [2014-11-01T10:00:00-07:00]>

I'm not sure what structure you want your resulting array in, but the following code will do what I think you're asking for:

int sum = 0;
int[] results = new int[100];
for (int i = 0; i < 100; i++) {
  sum += (i+1);
  results[i] = sum;
}

Gives you an array of the sum at each point in the loop [1, 3, 6, 10...]

With Android 8.0 using Custom Fonts in Application became easy with downloadable fonts. We can add fonts directly to the res/font/ folder in the project folder, and in doing so, the fonts become automatically available in Android Studio.

Now set fontFamily attribute to list of fonts or click on more and select font of your choice. This will add tools:fontFamily="@font/your_font_file" line to your TextView.

This will Automatically generate few files.

1. In values folder it will create fonts_certs.xml.

2. In Manifest it will add this lines:

  <meta-data
            android:name="preloaded_fonts"
            android:resource="@array/preloaded_fonts" /> 

3. preloaded_fonts.xml

<resources>
    <array name="preloaded_fonts" translatable="false">
        <item>@font/open_sans_regular</item>
        <item>@font/open_sans_semibold</item>
    </array>
</resources>

another solution, in development environment of course, is killing process using it, for example

def serve():
    server = HTTPServer(('', PORT_NUMBER), BaseHTTPRequestHandler)
    print 'Started httpserver on port ' , PORT_NUMBER
    server.serve_forever()
try:
    serve()
except Exception, e:
    print "probably port is used. killing processes using given port %d, %s"%(PORT_NUMBER,e)
    os.system("xterm -e 'sudo fuser -kuv %d/tcp'" % PORT_NUMBER)
    serve()
    raise e

If global tab/spaces indentation settings no longer fit your needs (I.E. you find yourself working with legacy codebases with varied indentation formats, and you need to quickly switch between them, and the auto-detect isn't working) you might try the tab-control plugin, which sort of duplicates the functionality of the menu in your screenshot.

For those very beginners who has spend few hours for this commit (with comment and no verify) with no further issue

git commit -m "Some comments" --no-verify

find specifiedpath -type d

If you don't want to recurse in subdirectories, you can do this instead:

find specifiedpath -type d -mindepth 1 -maxdepth 1

Note that "dot" directories (whose name start with .) will be listed too; but not the special directories . nor ... If you don't want "dot" directories, you can just grep them out:

find specifiedpath -type d -mindepth 1 -maxdepth 1 | grep -v '^\.'

Try to run this code:

del x[:N]

Here is the simple one line fix without css.

{{ myString | limitTo: 20 }}{{myString.length > 20 ? '...' : ''}}

In General:

An example of an easy way to post XML data and get the response (as a string) would be the following function:

public string postXMLData(string destinationUrl, string requestXml)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
    byte[] bytes;
    bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
    request.ContentType = "text/xml; encoding='utf-8'";
    request.ContentLength = bytes.Length;
    request.Method = "POST";
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);
    requestStream.Close();
    HttpWebResponse response;
    response = (HttpWebResponse)request.GetResponse();
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream responseStream = response.GetResponseStream();
        string responseStr = new StreamReader(responseStream).ReadToEnd();
        return responseStr;
    }
    return null;
}

In your specific situation:

Instead of:

request.ContentType = "application/x-www-form-urlencoded";

use:

request.ContentType = "text/xml; encoding='utf-8'";

Also, remove:

string postData = "XMLData=" + Sendingxml;

And replace:

byte[] byteArray = Encoding.UTF8.GetBytes(postData);

with:

byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());

To change the directory for target dll/exe, use this in your pro file:

CONFIG(debug, debug|release) {
    DESTDIR = build/debug
} else {
    DESTDIR = build/release
}

You might also want to change directories for other build targets like object files and moc files (check qmake variable reference for details or qmake CONFIG() function reference).

TL;DR:

Create another <ul class="navbar-nav ml-auto"> for the navbar items you want on the right.
ml-auto will pull your navbar-nav to the right where mr-auto will pull it to the left.

As you can see additional styling rules have been added to account for some oddities in Stackoverflows preview box.
You should be able to safely ignore those rules in your project.

As of v4.0.0 this seems to be the official way to do it.

EDIT: I modified the Post to include a dropdown placed on the right side of the navbar as suggested by @Bruno. It needs its left and right attributes to be inverted. I added an extra snippet of css to the beginning of the example code.
Please note, that the example shows the mobile version when you click the Run code snippet button. To view the desktop version you must click the Expand snippet button.

.ml-auto .dropdown-menu {
    left: auto !important;
    right: 0px;
}

Including this in your stylesheet should do the trick.

This is a good catch by Joe. The code example above has two problems - one - the response object isn't an instance of Bitmap (when my URL references a jpg, like http:\website.com\image.jpg, its a

org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl$LimitedInputStream).

Second, as Joe points out, no caching occurs without a response cache being configured. Android developers are left to roll their own cache. Here's an example for doing so, but it only caches in memory, which really isn't the full solution.

http://codebycoffee.com/2010/06/29/using-responsecache-in-an-android-app/

The URLConnection caching API is described here:

http://download.oracle.com/javase/6/docs/technotes/guides/net/http-cache.html

I still think this is an OK solution to go this route - but you still have to write a cache. Sounds like fun, but I'd rather write features.

Partly, because Go doesn't have generics (so you would need one set-type for every type, or fall back on reflection, which is rather inefficient).

Partly, because if all you need is "add/remove individual elements to a set" and "relatively space-efficient", you can get a fair bit of that simply by using a map[yourtype]bool (and set the value to true for any element in the set) or, for more space efficiency, you can use an empty struct as the value and use _, present = the_setoid[key] to check for presence.

Install tampermonkey and add the following UserScript with one (or more) @match with specific page url (or a match of all pages: https://*) e.g.:

// ==UserScript==
// @name         inject-rx
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  Inject rx library on the page
// @author       Me
// @match        https://www.some-website.com/*
// @require      https://cdnjs.cloudflare.com/ajax/libs/rxjs/6.5.4/rxjs.umd.min.js
// @grant        none
// ==/UserScript==

(function() {
    'use strict';
     window.injectedRx = rxjs;
     //Or even:  window.rxjs = rxjs;

})();

Whenever you need the library on the console, or on a snippet enable the specific UserScript and refresh.

This solution prevents namespace pollution. You can use custom namespaces to avoid accidental overwrite of existing global variables on the page.

Deny takes precedence over Allow. Local rules take precedence over inherited rules. I have seen many solutions (including some answers shown here), but none of them takes into account whether rules are inherited or not. Therefore I suggest the following approach that considers rule inheritance (neatly wrapped into a class):

public class CurrentUserSecurity
{
    WindowsIdentity _currentUser;
    WindowsPrincipal _currentPrincipal;

    public CurrentUserSecurity()
    {
        _currentUser = WindowsIdentity.GetCurrent();
        _currentPrincipal = new WindowsPrincipal(_currentUser);
    }

    public bool HasAccess(DirectoryInfo directory, FileSystemRights right)
    {
        // Get the collection of authorization rules that apply to the directory.
        AuthorizationRuleCollection acl = directory.GetAccessControl()
            .GetAccessRules(true, true, typeof(SecurityIdentifier));
        return HasFileOrDirectoryAccess(right, acl);
    }

    public bool HasAccess(FileInfo file, FileSystemRights right)
    {
        // Get the collection of authorization rules that apply to the file.
        AuthorizationRuleCollection acl = file.GetAccessControl()
            .GetAccessRules(true, true, typeof(SecurityIdentifier));
        return HasFileOrDirectoryAccess(right, acl);
    }

    private bool HasFileOrDirectoryAccess(FileSystemRights right,
                                          AuthorizationRuleCollection acl)
    {
        bool allow = false;
        bool inheritedAllow = false;
        bool inheritedDeny = false;

        for (int i = 0; i < acl.Count; i++) {
            var currentRule = (FileSystemAccessRule)acl[i];
            // If the current rule applies to the current user.
            if (_currentUser.User.Equals(currentRule.IdentityReference) ||
                _currentPrincipal.IsInRole(
                                (SecurityIdentifier)currentRule.IdentityReference)) {

                if (currentRule.AccessControlType.Equals(AccessControlType.Deny)) {
                    if ((currentRule.FileSystemRights & right) == right) {
                        if (currentRule.IsInherited) {
                            inheritedDeny = true;
                        } else { // Non inherited "deny" takes overall precedence.
                            return false;
                        }
                    }
                } else if (currentRule.AccessControlType
                                                  .Equals(AccessControlType.Allow)) {
                    if ((currentRule.FileSystemRights & right) == right) {
                        if (currentRule.IsInherited) {
                            inheritedAllow = true;
                        } else {
                            allow = true;
                        }
                    }
                }
            }
        }

        if (allow) { // Non inherited "allow" takes precedence over inherited rules.
            return true;
        }
        return inheritedAllow && !inheritedDeny;
    }
}

However, I made the experience that this does not always work on remote computers as you will not always have the right to query the file access rights there. The solution in that case is to try; possibly even by just trying to create a temporary file, if you need to know the access right before working with the "real" files.

I'd use this approach:

String randomString(final int length) {
    Random r = new Random(); // perhaps make it a class variable so you don't make a new one every time
    StringBuilder sb = new StringBuilder();
    for(int i = 0; i < length; i++) {
        char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
        sb.append(c);
    }
    return sb.toString();
}

If you want a byte[] you can do this:

byte[] randomByteString(final int length) {
    Random r = new Random();
    byte[] result = new byte[length];
    for(int i = 0; i < length; i++) {
        result[i] = r.nextByte();
    }
    return result;
}

Or you could do this

byte[] randomByteString(final int length) {
    Random r = new Random();
    StringBuilder sb = new StringBuilder();
    for(int i = 0; i < length; i++) {
        char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
        sb.append(c);
    }
    return sb.toString().getBytes();
}

After a lot of research, I finally figured this one out.

DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) { // Change `2.0` to the desired number of seconds.
   // Code you want to be delayed
}

This creates the desired "wait" effect in Swift 3 and Swift 4.

Inspired by a part of this answer.

If the ActiveDirectory module is present add

import-module activedirectory

before your code.

To check if exist try:

get-module -listavailable

ActiveDirectory module is default present in windows server 2008 R2, install it in this way:

Import-Module ServerManager
Add-WindowsFeature RSAT-AD-PowerShell

For have it to work you need at least one DC in the domain as windows 2008 R2 and have Active Directory Web Services (ADWS) installed on it.

For Windows Server 2008 read here how to install it

I recently ran into the similar issue with react-native application. iPhone OS version was 13.1 I uninstalled the application and tried to install the app and noticed both location and notification permissions were not prompted.

On checking the settings, I could see my application was enabled for location(from previous installation) however there was no corresponding entry against the notification Tried uninstalling and rebooting without setting the time, it didn't work. Btw, I also tried to download the Appstore app, still same behavior.

The issue was resolved only after setting the device time.

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)
    }
}

As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:

• For Israel: The minimum phone number length (excluding the country code) is 8 digits. - Official Source (Country Code 972)

• For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)

• For Solomon Islands its 5 for fixed line phones. - Source (country code 677)

... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.

Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:

String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
    boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
    if (isValid) {
        // Actions to perform if the number is valid
    } else {
        // Do necessary actions if its not valid 
    }
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse function instead of passing null.

If you can use JQuery, then using the JQuery :focus selector will do the needful

$(this).is(':focus');

I have looked at each of these solutions that also seem to work with one issue. Dark Mode and the background setting

The Background setting of the UITextField must match the background of the parent view or no line appears

So this will work on light mode To get to work in dark mode change the background color to black and it works Exclude back color and the line does not appear

let field = UITextField() 
field.backgroundColor = UIColor.white
field.bottomBorderColor = UIColor.red

This ended up being the best solution for me

extension UITextField {

    func addPadding() {
        let paddingView = UIView(frame: CGRect(x:0, y:0, width: 10, height: self.frame.height))
        self.leftView = paddingView
        self.leftViewMode = .always
      }

      @IBInspectable var placeHolderColor: UIColor? {
          get {
              return self.placeHolderColor
          }
          set {
            self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSAttributedString.Key.foregroundColor: newValue!])
          }
      }

      @IBInspectable var bottomBorderColor: UIColor? {
          get {
              return self.bottomBorderColor
          }
          set {
            self.borderStyle = .none
            self.layer.masksToBounds = false
            self.layer.shadowColor = newValue?.cgColor
            self.layer.shadowOffset = CGSize(width: 0.0, height: 1.0)
            self.layer.shadowOpacity = 1.0
            self.layer.shadowRadius = 0.0
          }
      }
    }

Here is my code.

import java.util.Date;

// to calculate difference between two days
public class DateDifference {

// to calculate difference between two dates in milliseconds
public long getDateDiffInMsec(Date da, Date db) {
    long diffMSec = 0;
    diffMSec = db.getTime() - da.getTime();
    return diffMSec;
}

// to convert Milliseconds into DD HH:MM:SS format.
public String getDateFromMsec(long diffMSec) {
    int left = 0;
    int ss = 0;
    int mm = 0;
    int hh = 0;
    int dd = 0;
    left = (int) (diffMSec / 1000);
    ss = left % 60;
    left = (int) left / 60;
    if (left > 0) {
        mm = left % 60;
        left = (int) left / 60;
        if (left > 0) {
            hh = left % 24;
            left = (int) left / 24;
            if (left > 0) {
                dd = left;
            }
        }
    }
    String diff = Integer.toString(dd) + " " + Integer.toString(hh) + ":"
            + Integer.toString(mm) + ":" + Integer.toString(ss);
    return diff;

}
}

It just associates a semaphore with every object, and uses that.

If anyone wanted nates' solution but in swift, then here is a rough swift translation:

class SomeClass: UIViewController {

    var animating : Bool = false
    @IBOutlet weak var activityIndicatorImage: UIImageView!

    func startSpinning() {
        if(!animating) {
            animating = true;
            spinWithOptions(UIViewAnimationOptions.CurveEaseIn);
        }
    }

    func stopSpinning() {
        animating = false
    }

    func spinWithOptions(options: UIViewAnimationOptions) {
        UIView.animateWithDuration(0.5, delay: 0.0, options: options, animations: { () -> Void in
            let val : CGFloat = CGFloat((M_PI / Double(2.0)));
            self.activityIndicatorImage.transform = CGAffineTransformRotate(self.activityIndicatorImage.transform,val)
        }) { (finished: Bool) -> Void in

            if(finished) {
                if(self.animating){
                    self.spinWithOptions(UIViewAnimationOptions.CurveLinear)
                } else if (options != UIViewAnimationOptions.CurveEaseOut) {
                    self.spinWithOptions(UIViewAnimationOptions.CurveEaseOut)
                }
            }

        }
    }

    override func viewDidLoad() {
        startSpinning()
    }
}

All the answers given using LIKEare totally valid, but as all of them noted will be slow. So if you have a lot of queries and not too many changes in the list of keywords, it pays to build a structure that allows for faster querying.

Here are some ideas:

If all you are looking for is the letters a-z and you don't care about uppercase/lowercase, you can add columns containsA .. containsZ and prefill those columns:

UPDATE table
SET containsA = 'X' 
WHERE UPPER(your_field) Like '%A%';

(and so on for all the columns).

Then index the contains.. columns and your query would be

SELECT 
FROM your_table
WHERE containsA = 'X'
AND containsB = 'X'

This may be normalized in an "index table" iTable with the columns your_table_key, letter, index the letter-column and your query becomes something like

SELECT
FROM your_table 
WHERE <key> in (select a.key
    From iTable a join iTable b and a.key = b.key
    Where a.letter = 'a'
    AND b.letter = 'b');

All of these require some preprocessing (maybe in a trigger or so), but the queries should be a lot faster.

Simply you can try this also

txtVw.setCompoundDrawablesWithIntrinsicBounds(R.drawable.smiley, 0, 0, 0);

You can customize the way that both the .fromNow and the .calendar methods display dates using moment.updateLocale. The following code will change the way that .calendar displays as per the question:

moment.updateLocale('en', {
    calendar : {
        lastDay : '[Yesterday]',
        sameDay : '[Today]',
        nextDay : '[Tomorrow]',
        lastWeek : '[Last] dddd',
        nextWeek : '[Next] dddd',
        sameElse : 'L'
    }
});

Based on the question, it seems like the .calendar method would be more appropriate -- .fromNow wants to have a past/present prefix/suffix, but if you'd like to find out more you can read the documentation at http://momentjs.com/docs/#/customization/relative-time/.

To use this in only one place instead of overwriting the locales, pass a string of your choice as the first argument when you define the moment.updateLocale and then invoke the calendar method using that locale (eg. moment.updateLocale('yesterday-today').calendar( /* moment() or whatever */ ))

EDIT: Moment ^2.12.0 now has the updateLocale method. updateLocale and locale appear to be functionally the same, and locale isn't yet deprecated, but updated the answer to use the newer method.

INT_MAX is just a definition in limits.h. You don't make it clear whether you need to store an integer or floating point value. If integer, and using a 64-bit compiler, use a LONG (LLONG for 32-bit).

I think this may help:

Secondly, you need to be aware that the checked attribute RETURNS a string "true", "false"
Why is this important? Because you need to use the correct Type. A string, not a boolean. This also important when parsing your checkbox.
$('mycheckbox')[0].checked = "true"

if($('mycheckbox')[0].checked === "true"){ //do something }

You also need to realize that the "checked" ATTRIBUTE is for setting the value of the checkbox initially. This doesn't do much once the element is rendered to the DOM. Picture this working when the webpage loads and is initially parsed.
I'll go with IE's preference on this one: <input type="checkbox" checked="checked"/>

Lastly, the main aspect of confusion for a checkbox is that the checkbox UI element is not the same as the element's property value. They do not correlate directly. If you work in .net, you'll discover that the user "checking" a checkbox never reflects the actual bool value passed to the controller. To set the UI, I use both $('mycheckbox').val(true); and $('mycheckbox').attr('checked', 'checked');

Well, in my case updating drivers, restarting Android Studio, restarting my phone, changing the USB mode or unplugging USB did not help.

Then I went to the dev settings in my phone, toggled the Dev. Mode off and back on, and it worked. AS was open and phone was plugged at the moment.

-z

string is null, that is, has zero length

String=''   # Zero-length ("null") string variable.

if [ -z "$String" ]
then
  echo "\$String is null."
else
  echo "\$String is NOT null."
fi     # $String is null.

var obj = jQuery.parseJSON('{"name":"John"}');
alert( obj.name === "John" );

I tried the answer described here but it doesn´t worked for me. I have the last Android SDK tools ver. 23.0.2 and Android SDK Platform-tools ver. 20

The support library android-support-v4.jar is causing this conflict, just delete the library under /libs folder of your project, don´t be scared, the library is already contained in the library appcompat_v7, clean and build your project, and your project will work like a charm!

I met this issue this morning because I used the same executable in DIFFERENT OSes: after compiling my program with gcc -ggdb -Wall test.c -o test in my Mac(10.15.2), I ran gdb with the executable in Ubuntu(16.04) in my VirtualBox.

Fix: recompile with the same command under Ubuntu, then you should be good.

Please try the below this is the easiest way and it works perfectly

var newSkill_Text = document.getElementById("newSkill")[document.getElementById("newSkill").selectedIndex];

What you want to do is prevent the default action of the click event. To do this, you will need to modify your script like this:

$(document).ready(function() {
  $('.galleryicon').live("click", function(e) {

    $('#mainImage').hide();
    $('#cakebox').css('background-image', "url('ajax-loader.gif')");
    var i = $('<img />').attr('src',this.href).load(function() {
        $('#mainImage').attr('src', i.attr('src'));
        $('#cakebox').css('background-image', 'none');
        $('#mainImage').fadeIn();
    });
    return false; 
    e.preventDefault();
   });
 });

So, you're adding an "e" that represents the event in the line $('.galleryicon').live("click", function(e) { and you're adding the line e.preventDefault();

function StopWatch() {
    let startTime, endTime, running, duration = 0
    
    this.start = () => {
        if (running) console.log('its already running')
        else {
            running = true
            startTime = Date.now()
        }
    }

    this.stop = () => {
        if (!running) console.log('its not running!')
        else {
            running = false
            endTime = Date.now()

            const seconds = (endTime - startTime) / 1000
            duration += seconds
        }
    }

    this.restart = () => {
        startTime = endTime = null
        running = false
        duration = 0
    }
    
    Object.defineProperty(this, 'duration', {
        get: () => duration.toFixed(2)
    })

}

const sw =  new StopWatch()

sw.start()
sw.stop()

sw.duration

It is confirmed that Windows 7 and newer versions (at least 64bit or both) do not use system speaker and instead they route the call to the default sound device.

So, using system.beep() in win7/8/10 will not produce sound using internal system speaker. Instead, you'll get a beep sound from external speakers if they are available.

Every derived table (AKA sub-query) must indeed have an alias. I.e. each query in brackets must be given an alias (AS whatever), which can the be used to refer to it in the rest of the outer query.

SELECT ID FROM (
    SELECT ID, msisdn FROM (
        SELECT * FROM TT2
    ) AS T
) AS T

In your case, of course, the entire query could be replaced with:

SELECT ID FROM TT2

What is java.lang.StackOverflowError

The error java.lang.StackOverflowError is thrown to indicate that the application’s stack was exhausted, due to deep recursion i.e your program/script recurses too deeply.

Details

The StackOverflowError extends VirtualMachineError class which indicates that the JVM have been or have run out of resources and cannot operate further. The VirtualMachineError which extends the Error class is used to indicate those serious problems that an application should not catch. A method may not declare such errors in its throw clause because these errors are abnormal conditions that was never expected to occur.

An Example

Minimal, Complete, and Verifiable Example :

package demo;

public class StackOverflowErrorExample {

    public static void main(String[] args) 
    {
        StackOverflowErrorExample.recursivePrint(1);
    }

    public static void recursivePrint(int num) {
        System.out.println("Number: " + num);

        if(num == 0)
            return;
        else
            recursivePrint(++num);
    }

}

Explaination

When a function call is invoked by a Java Application, a stack frame is allocated on the call stack. The stack frame contains the parameters of the invoked method, its local parameters, and the return address of the method. The return address denotes the execution point from which, the program execution shall continue after the invoked method returns. If there is no space for a new stack frame then, the StackOverflowError is thrown by the Java Virtual Machine (JVM).

The most common case that can possibly exhaust a Java application’s stack is recursion. In recursion, a method invokes itself during its execution. Recursion one of the most powerful general-purpose programming technique, but must be used with caution, in order for the StackOverflowError to be avoided.

To get a char from a Scanner, you can use the findInLine method.

    Scanner sc = new Scanner("abc");
    char ch = sc.findInLine(".").charAt(0);
    System.out.println(ch); // prints "a"
    System.out.println(sc.next()); // prints "bc"

If you need a bunch of char from a Scanner, then it may be more convenient to (perhaps temporarily) change the delimiter to the empty string. This will make next() returns a length-1 string every time.

    Scanner sc = new Scanner("abc");
    sc.useDelimiter("");
    while (sc.hasNext()) {
        System.out.println(sc.next());
    } // prints "a", "b", "c"

HTML5 + spark-md5 and Q

Assuming your'e using a modern browser (that supports HTML5 File API), here's how you calculate the MD5 Hash of a large file (it will calculate the hash on variable chunks)

function calculateMD5Hash(file, bufferSize) {
  var def = Q.defer();

  var fileReader = new FileReader();
  var fileSlicer = File.prototype.slice || File.prototype.mozSlice || File.prototype.webkitSlice;
  var hashAlgorithm = new SparkMD5();
  var totalParts = Math.ceil(file.size / bufferSize);
  var currentPart = 0;
  var startTime = new Date().getTime();

  fileReader.onload = function(e) {
    currentPart += 1;

    def.notify({
      currentPart: currentPart,
      totalParts: totalParts
    });

    var buffer = e.target.result;
    hashAlgorithm.appendBinary(buffer);

    if (currentPart < totalParts) {
      processNextPart();
      return;
    }

    def.resolve({
      hashResult: hashAlgorithm.end(),
      duration: new Date().getTime() - startTime
    });
  };

  fileReader.onerror = function(e) {
    def.reject(e);
  };

  function processNextPart() {
    var start = currentPart * bufferSize;
    var end = Math.min(start + bufferSize, file.size);
    fileReader.readAsBinaryString(fileSlicer.call(file, start, end));
  }

  processNextPart();
  return def.promise;
}

function calculate() {

  var input = document.getElementById('file');
  if (!input.files.length) {
    return;
  }

  var file = input.files[0];
  var bufferSize = Math.pow(1024, 2) * 10; // 10MB

  calculateMD5Hash(file, bufferSize).then(
    function(result) {
      // Success
      console.log(result);
    },
    function(err) {
      // There was an error,
    },
    function(progress) {
      // We get notified of the progress as it is executed
      console.log(progress.currentPart, 'of', progress.totalParts, 'Total bytes:', progress.currentPart * bufferSize, 'of', progress.totalParts * bufferSize);
    });
}

Use System.out.format . You can set lengths of fields like this:

System.out.format("%32s%10d%16s", string1, int1, string2);

This pads string1, int1, and string2 to 32, 10, and 16 characters, respectively.

See the Javadocs for java.util.Formatter for more information on the syntax (System.out.format uses a Formatter internally).

You can have a look at the EL (expression language) description here.

Both your code are correct, but I prefer the second one, as comparing a boolean to true or false is redundant.

For better readibility, you can also use the not operator:

<c:if test="${not theBooleanVariable}">It's false!</c:if>

Two problems here:

1. seven_date is a number, not a date. 29 + 7 = 36
2. getMonth returns a zero based index of the month. So adding one just gets you the current month number.

I created this reference of my most used command for a friend of mine:

If you are using Outlook 2010, you can define your own style and select your formatting you want, in the Format options there is one option for Language, here you can specify the language and specify whether you want spell checker to ignore the text with this style.

With this style you can now paste the code as text and select your new style. Outlook will not correct the text and will not perform the spell check on it.

Below is the summary of the style I have defined for emailing the code snippets.

Do not check spelling or grammar, Border:
Box: (Single solid line, Orange,  0.5 pt Line width)
Pattern: Clear (Custom Color(RGB(253,253,217))), Style: Linked, Automatically update, Quick Style
Based on: HTML Preformatted

If it is because of the overhead in terms of creating objects, then it probably can't be sped up at all with SA.

If it is because it is loading up related objects, then you might be able to do something with lazy loading. Are there lots of objects being created due to references? (IE, getting a Company object also gets all of the related People objects).

Based on the accepted answer, for those who encountered a similar issue, with full schema qualification:

([MyDataBase].[MySchemaName].[MyTable])... results in an error, you need to be in the context of that DB

That is, the following will throw an error:

DBCC CHECKIDENT ([MyDataBase].[MySchemaName].[MyTable], RESEED, 0)

Enclose the fully-qualified table name with single quotes instead:

DBCC CHECKIDENT ('[MyDataBase].[MySchemaName].[MyTable]', RESEED, 0)

Perhaps not in the context that you have it, but you could use

SELECT DISTINCT col1,
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1),
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1, col3),
FROM TableA

You would use this to return different levels of aggregation returned in a single row. The use case would be for when a single grouping would not suffice all of the aggregates needed.

You need to change || to && so that both conditions must be true to enter the loop.

while(myChar != 'n' && myChar != 'N')

• "r" is the same as "rt" for Translated mode
• "rb" is non-translated mode.

This makes a difference on Windows, at least. See that link for details.

This utility function merge multiple functions into one (using a custom name), only requirement is that provided functions are properly "new lined" at start and end of its scoop.

const createFn = function(name, functions, strict=false) {

    var cr = `\n`, a = [ 'return function ' + name + '(p) {' ];

    for(var i=0, j=functions.length; i<j; i++) {
        var str = functions[i].toString();
        var s = str.indexOf(cr) + 1;
        a.push(str.substr(s, str.lastIndexOf(cr) - s));
    }
    if(strict == true) {
        a.unshift('\"use strict\";' + cr)
    }
    return new Function(a.join(cr) + cr + '}')();
}

// test
var a = function(p) {
    console.log("this is from a");
}
var b = function(p) {
    console.log("this is from b");
}
var c = function(p) {
    console.log("p == " + p);
}

var abc = createFn('aGreatName', [a,b,c])

console.log(abc) // output: function aGreatName()

abc(123)

// output
this is from a
this is from b
p == 123

scrollHeight is a regular javascript property so you don't need jQuery.

var test = document.getElementById("foo").scrollHeight;

try {

    SimpleDateFormat format = new SimpleDateFormat("hh:mm a"); //if 24 hour format
    // or
    SimpleDateFormat format = new SimpleDateFormat("HH:mm"); // 12 hour format

    java.util.Date d1 =(java.util.Date)format.parse(your_Time);

    java.sql.Time ppstime = new java.sql.Time(d1.getTime());

} catch(Exception e) {

    Log.e("Exception is ", e.toString());
}

You can get value of key like this...

var obj = {
   a: "A",
   b: "B",
   c: "C"
};

console.log(obj.a);

console.log(obj['a']);

name = "a";
console.log(obj[name])

The simplest and the most efficient way is to use an uber plugin like this:

          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <finalName>uber-${project.artifactId}-${project.version}</finalName>
            </configuration>
        </plugin>

You will have de-normalized all in one JAR file.

Since :last-child is a CSS3 pseudo-class, it is not supported in IE8. I believe :first-child is supported, as it's defined in the CSS2.1 specification.

One possible solution is to simply give the last child a class name and style that class.

Another would be to use JavaScript. jQuery makes this particularly easy as it provides a :last-child pseudo-class which should work in IE8. Unfortunately, that could result in a flash of unstyled content while the DOM loads.

myString.substring(str.length,str.length-1)

You should be able to do something like the above - which will get the last character

^M is carriage return. You can do this:

$str =~ s/\r//g

public class camera_act extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera_act);
         ImageView imageView = findViewById(R.id.image);
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent,90);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode,resultCode,data);
       Bitmap bitmap = data.getExtras.get("imageKey");
       imageView.setBitmapImage(bitmap);
            
        }
    }
}

In case you are running

• Cisco AnyConnect Secure Mobility Agent
• Cisco AnyConnect Web Security Agent

try stopping the service(s).

Not sure why I got a down vote for this answer. In our corporate network this IS the solution to the issue.

I recommend checking out Microsoft's SQL Server sample databases: https://github.com/Microsoft/sql-server-samples/releases/tag/adventureworks

The AdventureWorks sample uses a very clear and consistent naming convention that uses schema names for the organization of database objects.

1. Singular names for tables
2. Singular names for columns
3. Schema name for tables prefix (E.g.: SchemeName.TableName)
4. Pascal casing (a.k.a. upper camel case)

I follow this simple setup with meld. Meld is free and opensource diff tool. You will see nice side by side comparison of files and directory for any code changes.

1. Install meld in your Linux using yum/apt.
2. Add following line in your ~/.gitconfig file

[diff]
    tool = meld

3. Go to your code repo and type following command to see difference between last committed changes and current working directory (Unstaged uncommited changes)

git difftool --dir-diff ./

4. To see difference between last committed code and staged code, use following command

git difftool --cached --dir-diff ./

As others have pointed out, there are many web frameworks for Python.

But, seeing as you are just getting started with Python, a simple CGI script might be more appropriate:

1. Rename your script to index.cgi. You also need to execute chmod +x index.cgi to give it execution privileges.

2. Add these 2 lines in the beginning of the file:

#!/usr/bin/python   
print('Content-type: text/html\r\n\r')

After this the Python code should run just like in terminal, except the output goes to the browser. When you get that working, you can use the cgi module to get data back from the browser.

Note: this assumes that your webserver is running Linux. For Windows, #!/Python26/python might work instead.

In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,

default_days     = 1000         # How long to certify for

defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:

openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.

A very simple work-around for this issue is to create a Streamable<T> interface extending Iterable<T> that holds a default <T> stream() method.

interface Streamable<T> extends Iterable<T> {
    default Stream<T> stream() {
        return StreamSupport.stream(spliterator(), false);
    }
}

Now any of your Iterable<T>s can be trivially made streamable just by declaring them implements Streamable<T> instead of Iterable<T>.

I found my solution here. In short make sure not only the Eclipse plugin(if you are using eclipse) is updated. Also ensure that the Android SDK Tools, the SDK platform-tools and the SDK Build-tools are updated. After this restart your machine.

SyntaxError: non-default argument follows default argument

If you were to allow this, the default arguments would be rendered useless because you would never be able to use their default values, since the non-default arguments come after.

In Python 3 however, you may do the following:

def fun1(a="who is you", b="True", *, x, y):
    pass

which makes x and y keyword only so you can do this:

fun1(x=2, y=2)

This works because there is no longer any ambiguity. Note you still can't do fun1(2, 2) (that would set the default arguments).

Get requests should not have content-type because they do not have request entity (that is, a body)

I think if you are looking for fullscreen only, no need to set geometry or maxsize etc.

You just need to do this:

-If you are working on ubuntu:

root=tk.Tk()
root.attributes('-zoomed', True)

-and if you are working on windows:

root.state('zoomed')

Now for toggling between fullscreen, for minimising it to taskbar you can use:

Root.iconify()

Do you want to open a shared folder in Windows Explorer? You need to use a file: link, but there are caveats:

• Internet Explorer will work if the link is a converted UNC path (file://server/share/folder/).
• Firefox will work if the link is in its own mangled form using five slashes (file://///server/share/folder) and the user has disabled the security restriction on file: links in a page served over HTTP. Thankfully IE also accepts the mangled link form.
• Opera, Safari and Chrome can not be convinced to open a file: link in a page served over HTTP.

In my case it was the problem of building the extension, I was pointing at an extension src (with manifest and everything) but without a build.

If you run into this scenario run npm i then npm build

What about:

#region Using Statements
using System;
using System.Xml;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XmlDocument doc = new XmlDocument( );

        //(1) the xml declaration is recommended, but not mandatory
        XmlDeclaration xmlDeclaration = doc.CreateXmlDeclaration( "1.0", "UTF-8", null );
        XmlElement root = doc.DocumentElement;
        doc.InsertBefore( xmlDeclaration, root );

        //(2) string.Empty makes cleaner code
        XmlElement element1 = doc.CreateElement( string.Empty, "body", string.Empty );
        doc.AppendChild( element1 );

        XmlElement element2 = doc.CreateElement( string.Empty, "level1", string.Empty );
        element1.AppendChild( element2 );

        XmlElement element3 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text1 = doc.CreateTextNode( "text" );
        element3.AppendChild( text1 );
        element2.AppendChild( element3 );

        XmlElement element4 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text2 = doc.CreateTextNode( "other text" );
        element4.AppendChild( text2 );
        element2.AppendChild( element4 );

        doc.Save( "D:\\document.xml" );
    }
}

_{(1) Does a valid XML file require an xml declaration?
(2) What is the difference between String.Empty and “” (empty string)?}

The result is:

<?xml version="1.0" encoding="UTF-8"?>
<body>
  <level1>
    <level2>text</level2>
    <level2>other text</level2>
  </level1>
</body>

But I recommend you to use LINQ to XML which is simpler and more readable like here:

#region Using Statements
using System;
using System.Xml.Linq;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XDocument doc = new XDocument( new XElement( "body", 
                                           new XElement( "level1", 
                                               new XElement( "level2", "text" ), 
                                               new XElement( "level2", "other text" ) ) ) );
        doc.Save( "D:\\document.xml" );
    }
}

If you are using opencv3, you can print Mat like python numpy style:

Mat xTrainData = (Mat_<float>(5,2) << 1, 1, 1, 1, 2, 2, 2, 2, 2, 2);

cout << "xTrainData (python)  = " << endl << format(xTrainData, Formatter::FMT_PYTHON) << endl << endl;

Output as below, you can see it'e more readable, see here for more information.

But in most case, there is no need to output all the data in Mat, you can output by row range like 0 ~ 2 row:

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

#include <iostream>
#include <iomanip>

using namespace cv;
using namespace std;

int main(int argc, char** argv)
{
    //row: 6, column: 3,unsigned one channel
    Mat image1(6, 3, CV_8UC1, 5);

    // output row: 0 ~ 2
    cout << "image1 row: 0~2 = "<< endl << " "  << image1.rowRange(0, 2) << endl << endl;

    //row: 8, column: 2,unsigned three channel
    Mat image2(8, 2, CV_8UC3, Scalar(1, 2, 3));

    // output row: 0 ~ 2
    cout << "image2 row: 0~2 = "<< endl << " "  << image2.rowRange(0, 2) << endl << endl;

    return 0;
}

Output as below:

Write your migration manually. E.g. run rails g migration DropUsers.

As for the code of the migration I'm just gonna quote Maxwell Holder's post Rails Migration Checklist

BAD - running rake db:migrate and then rake db:rollback will fail

class DropUsers < ActiveRecord::Migration
  def change
    drop_table :users
  end
end

GOOD - reveals intent that migration should not be reversible

class DropUsers < ActiveRecord::Migration
  def up
    drop_table :users
  end

  def down
    fail ActiveRecord::IrreversibleMigration
  end
end

BETTER - is actually reversible

class DropUsers < ActiveRecord::Migration
  def change
    drop_table :users do |t|
      t.string :email, null: false
      t.timestamps null: false
    end
  end
end

The click handler that you are trying to trigger is most likely also attached via $(document).ready(). What is probably happening is that you are triggering the event before the handler is attached. The solution is to use setTimeout:

$("document").ready(function() {
    setTimeout(function() {
        $("ul.galleria li:first-child img").trigger('click');
    },10);
});

A delay of 10ms will cause the function to run immediately after all the $(document).ready() handlers have been called.

OR you check if the element is ready:

$("document").ready(function() {
  $("ul.galleria li:first-child img").ready(function() {
    $(this).click();
  });    
});

Just like in Java, using CommonsIO library:

FileUtils.readFileToString(file, StandardCharsets.UTF_8)

Also, many answers here forget Charset. It's better to always provide it explicitly, or it will hit one day.

A simpler way would be to create a link called cudart64_101.dll to point to cudart64_102.dll. This is not very orthodox but since TensorFlow is looking for cudart64_101.dll exported symbols and the nvidia folks are not amateurs, they would most likely not remove symbols from 101 to 102. It works, based on this assumption (mileage may vary).

I had the same problem but solved it when I realized that I didn't compile it with the correct casing. You may have been doing

javac Weatherarray.java

when it should have been

javac WeatherArray.java

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>   
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>      
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option> 
</select>

It's an abbreviation of Error NO ENTry (or Error NO ENTity), and can actually be used for more than files/directories.

It's abbreviated because C compilers at the dawn of time didn't support more than 8 characters in symbols.

If your app use multiple webview you will still have troubles : localStorage is not correctly shared accross all webviews.

If you want to share the same data in multiple webviews the only way is to repair it with a java database and a javascript interface.

This page on github shows how to do this.

hope this help!

You have to use FirebaseMessagingService() instead of FirebaseInstanceIdService

OAuth 2.0 is a Security protocol. It is NEITHER an Authentication NOR an Authorization protocol.

Authentication by definition the answers two questions.

1. Who is the user?
2. Is the user currently present on the system?

OAuth 2.0 has the following grant types

• client_credentials: When one app needs to interact with another app and modify the data of multiple users.
• authorization_code: User delegates the Authorization server to issue an access_token that the client can use to access protected resource
• refresh_token: When the access_token expires, the refresh token can be leveraged to get a fresh access_token
• password: User provides their login credentials to a client that calls the Authorization server and receives an access_token

All 4 have one thing in common, access_token, an artifact that can be used to access protected resource.

The access_token does not provide the answer to the 2 questions that an "Authentication" protocol must answer.

An example to explain Oauth 2.0 (credits: OAuth 2 in Action, Manning publications)

Let's talk about chocolate. We can make many confections out of chocolate including, fudge, ice cream, and cake. But, none of these can be equated to chocolate because multiple other ingredients such as cream and bread are needed to make the confection, even though chocolate sounds like the main ingredient. Similarly, OAuth 2.0 is the chocolate, and cookies, TLS infrastucture, Identity Providers are other ingredients that are required to provide the "Authentication" functionality.

If you want Authentication, you may go for OpenID Connect, which provides an "id_token", apart from an access_token, that answers the questions that every authentication protocol must answer.

If I was you, I would implement my own solution based on the event specs. Basically, what swipe is - it's handling of touch down, touch move, touch up events. here is excerpt of my own lib for handling iPhone touch events:

touch_object.prototype.handle_touchstart = function(e){
    if (e.targetTouches.length != 1){
        return false;
    }
    this.obj.style.zIndex = 100;
    e.preventDefault();
    this.startX = e.targetTouches[0].pageX - this.geometry.x;
    this.startY = e.targetTouches[0].pageY - this.geometry.y;
    /* adjust for left /top */
    this.bind_handler('touchmove');
    this.bind_handler('touchend');
}
touch_object.prototype.handle_touchmove = function(e) {
    e.preventDefault();
    if (e.targetTouches.length != 1){
        return false;
    }
    var x=e.targetTouches[0].pageX - this.startX;
    var y=e.targetTouches[0].pageY - this.startY;
    this.move(x,y);

}
touch_object.prototype.handle_touchend = function(e){
    this.obj.style.zIndex = 10;
    this.unbind_handler('touchmove');
    this.unbind_handler('touchend');
}

I used that code to "move things around". But, instead of moving, you can create your own algorithm for e.g. triggering redirect to some other location, or you can use that move to "move/swipe" the element, on which the swipe is on to other location.

so, it really helps to understand basics of how things work and then create more complicated solutions. this might help as well.

I used this, to create my solution:

http://developer.apple.com/library/IOs/#documentation/AppleApplications/Reference/SafariWebContent/HandlingEvents/HandlingEvents.html

I had the same issue. It's solved by adding following lines in .bashrc:

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

You have to run a web server (e.g. Apache) and browse to your localhost, mostly likely on port 80.

What you really ought to do is install an all-in-one package like XAMPP, it bundles Apache, MySQL PHP, and Perl (if you were so inclined) as well as a few other tools that work with Apache and MySQL - plus it's cross platform (that's what the 'X' in 'XAMPP' stands for).

Once you install XAMPP (and there is an installer, so it shouldn't be hard) open up the control panel for XAMPP and then click the "Start" button next to Apache - note that on applications that require a database, you'll also need to start MySQL (and you'll be able to interface with it through phpMyAdmin). Once you've started Apache, you can browse to http://localhost.

Again, regardless of whether or not you choose XAMPP (which I would recommend), you should just have to start Apache.

1. if there is not config.fish in ~/.config/fish/, make it.
2. there you can write your function .function name; command; end

try this:

static String getKeyFromValue(LinkedHashMap<String, String> map,String value) {
    for (int x=0;x<map.size();x++){
        if( String.valueOf( (new ArrayList<String>(map.values())).get(x) ).equals(value))
            return String.valueOf((new ArrayList<String>(map.keySet())).get(x));
    }
    return null;
}

I'd suggest try the change event? test to see if it has a value if it does then you can continue with your code. jQuery has

.bind("change", function(){ ... });

Or

.change(function(){ ... }); 

which are equivalents.

http://api.jquery.com/change/

for a unique selector change your name attribute to id and then jQuery("#imafile") or a general jQuery('input[type="file"]') for all the file inputs

You can solve this problem with vanilla-Js:

Unload Basics

If you want to prompt or warn your user that they're going to close your page, you need to add code that sets .returnValue on a beforeunload event:

    window.addEventListener('beforeunload', (event) => {
      event.returnValue = `Are you sure you want to leave?`;
    });

There's two things to remember.

1. Most modern browsers (Chrome 51+, Safari 9.1+ etc) will ignore what you say and just present a generic message. This prevents webpage authors from writing egregious messages, e.g., "Closing this tab will make your computer EXPLODE! ".

2. Showing a prompt isn't guaranteed. Just like playing audio on the web, browsers can ignore your request if a user hasn't interacted with your page. As a user, imagine opening and closing a tab that you never switch to—the background tab should not be able to prompt you that it's closing.

Optionally Show

You can add a simple condition to control whether to prompt your user by checking something within the event handler. This is fairly basic good practice, and could work well if you're just trying to warn a user that they've not finished filling out a single static form. For example:

    let formChanged = false;
    myForm.addEventListener('change', () => formChanged = true);
    window.addEventListener('beforeunload', (event) => {
      if (formChanged) {
        event.returnValue = 'You have unfinished changes!';
      }
    });

But if your webpage or webapp is reasonably complex, these kinds of checks can get unwieldy. Sure, you can add more and more checks, but a good abstraction layer can help you and have other benefits—which I'll get to later. ???

Promises

So, let's build an abstraction layer around the Promise object, which represents the future result of work- like a response from a network fetch().

The traditional way folks are taught promises is to think of them as a single operation, perhaps requiring several steps- fetch from the server, update the DOM, save to a database. However, by sharing the Promise, other code can leverage it to watch when it's finished.

Pending Work

Here's an example of keeping track of pending work. By calling addToPendingWork with a Promise—for example, one returned from fetch()—we'll control whether to warn the user that they're going to unload your page.

    const pendingOps = new Set();

    window.addEventListener('beforeunload', (event) => {
      if (pendingOps.size) {
        event.returnValue = 'There is pending work. Sure you want to leave?';
      }
    });

    function addToPendingWork(promise) {
      pendingOps.add(promise);
      const cleanup = () => pendingOps.delete(promise);
      promise.then(cleanup).catch(cleanup);
    }

Now, all you need to do is call addToPendingWork(p) on a promise, maybe one returned from fetch(). This works well for network operations and such- they naturally return a Promise because you're blocked on something outside the webpage's control.

The ONESHELL directive allows to write multiple line recipes to be executed in the same shell invocation.

all: foo

SOURCE_FILES = $(shell find . -name '*.c')

.ONESHELL:
foo: ${SOURCE_FILES}
    FILES=()
    for F in $^; do
        FILES+=($${F})
    done
    gcc "$${FILES[@]}" -o $@

There is a drawback though : special prefix characters (‘@’, ‘-’, and ‘+’) are interpreted differently.

I came up with a shorter solution, but it's using lodash. Works with any data, not just strings. For objects can be used:

const mostFrequent = _.maxBy(Object.values(_.groupBy(inputArr, el => el.someUniqueProp)), arr => arr.length)[0];

This is for strings:

const mostFrequent = _.maxBy(Object.values(_.groupBy(inputArr, el => el)), arr => arr.length)[0];

Just grouping data under a certain criteria, then finding the largest group.

This code will remove the indentation and list bullets.

ul {
    padding: 0;
    list-style-type: none;
}

I've figured out what the issue is the namespace is ambigious in the loggerFactory.AddLog4Net(). Here is a brief summary of how I added log4Net to my Asp.Net Core project.

1. Add the nugget package Microsoft.Extensions.Logging.Log4Net.AspNetCore

2. Add the log4net.config file in your root application folder

3. Open the Startup.cs file and change the Configure method to add log4net support with this line loggerFactory.AddLog4Net

First you have to import the package using Microsoft.Extensions.Logging; using the using statement

Here is the entire method, you have to prefix the ILoggerFactory interface with the namespace

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, NorthwindContext context, Microsoft.Extensions.Logging.ILoggerFactory loggerFactory)
        {
            loggerFactory.AddLog4Net();
            ....
        }

You can Change Backcolor row by row using your condition.and this function call after applying Datasource of DatagridView.

Here Is the function for that. Simply copy that and put it after Databind

private void ChangeRowColor()
{
    for (int i = 0; i < gvItem.Rows.Count; i++)
    {
        if (BindList[i].MainID == 0 && !BindList[i].SchemeID.HasValue)
            gvItem.Rows[i].DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#C9CADD");
        else if (BindList[i].MainID > 0 && !BindList[i].SchemeID.HasValue)
            gvItem.Rows[i].DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#DDC9C9");
        else if (BindList[i].MainID > 0)
            gvItem.Rows[i].DefaultCellStyle.BackColor = ColorTranslator.FromHtml("#D5E8D7");
        else
            gvItem.Rows[i].DefaultCellStyle.BackColor = Color.White;
    }
}

At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.

You should create an installer, as mentioned before. Even though it is also possible to let py2exe bundle everything into a single executable, by setting bundle_files option to 1 and the zipfile keyword argument to None, I don't recommend this for PyGTK applications.

That's because of GTK+ tries to load its data files (locals, themes, etc.) from the directory it was loaded from. So you have to make sure that the directory of your executable contains also the libraries used by GTK+ and the directories lib, share and etc from your installation of GTK+. Otherwise you will get problems running your application on a machine where GTK+ is not installed system-wide.

For more details read my guide to py2exe for PyGTK applications. It also explains how to bundle everything, but GTK+.

code example below:

g.setFont(new Font("TimesRoman", Font.PLAIN, 30));
g.drawString("Welcome to the Java Applet", 20 , 20);

I experienced the same problem, but for different reasons.

After Will Madden's solution didn't help, I tried every alternative fix I could find via the Intertubes - also to no avail. Exploring further, I just happened to open up one of the font files at issue. The original content of the file had somehow been overwritten by Webpack to include some kind of configuration info, likely from previous tinkering with the file-loader. I replaced the corrupted files with the originals, and voilà, the errors disappeared (for both Chrome and Firefox).

open kafka-run-class.sh with sudo to write

Modify the JAVA variable in the else part to point to the java executable in your java/bin. like JAVA="$JAVA_HOME/java"

CKEDITOR.instances = new Array();

I am using this before my calls to create an instance (ones per page load). Not sure how this affects memory handling and what not. This would only work if you wanted to replace all of the instances on a page.

Also, using the StringBuilder.AppendLine method.

Add your code to the onload event. The accepted answer shows this correctly, however that answer as well as all the others at the time of writing also suggest putting the script tag after the closing body tag, .

This is not valid html. However it will cause your code to work, because browsers are too kind ;)

See this answer for more info Is it wrong to place the <script> tag after the </body> tag?

Downvoted other answers for this reason.

Just use

 as.Date("2001-01-01") + 45

from base R, or date functionality in one of the many contributed packages. My RcppBDT package wraps functionality from Boost Date_Time including things like 'date of third Wednesday' in a given month.

Edit: And egged on by @Andrie, here is a bit more from RcppBDT (which is mostly a test case for Rcpp modules, really).

Even without cloning or fetching, you can check the list of tags on the upstream repo with git ls-remote:

git ls-remote --tags /url/to/upstream/repo

(as illustrated in "When listing git-ls-remote why there's “^{}” after the tag name?")

xbmono illustrates in the comments that quotes are needed:

git ls-remote --tags /some/url/to/repo "refs/tags/MyTag^{}"

Note that you can always push your commits and tags in one command with (git 1.8.3+, April 2013):

git push --follow-tags

See Push git commits & tags simultaneously.

Regarding Atlassian SourceTree specifically:

Note that, from this thread, SourceTree ONLY shows local tags.

There is an RFE (Request for Enhancement) logged in SRCTREEWIN-4015 since Dec. 2015.

A simple workaround:

see a list of only unpushed tags?

git push --tags

or check the "Push all tags" box on the "Push" dialog box, all tags will be pushed to your remote.

That way, you will be "sure that they are present in remote so that other developers can pull them".

I found that I can run this command:

notepad $((Split-Path $profile -Parent) + "\profile.ps1")

and it opens my default powershell profile (at least when using Terminal for Windows). I found that here.

Then add an alias. For example, here is my alias of jn for jupyter notebook (I hate typing out the cumbersome jupyter notebook every time):

Set-Alias -Name jn -Value C:\Users\words\Anaconda3\Scripts\jupyter-notebook.exe

You didn't do what you're being asked to do.

What is asked:

I have to execute ../gradlew build

What you do

cd ..
gradlew build

That's not the same thing.

The first one will use the gradlew command found in the .. directory (mdeinum...), and look for the build file to execute in the current directory, which is (for example) chapter1-bookstore.

The second one will execute the gradlew command found in the current directory (mdeinum...), and look for the build file to execute in the current directory, which is mdeinum....

So the build file executed is not the same.

For me the problem was associating RVM Ruby with Passenger. So I needed to integrate RVM ruby wrapper to passenger config file.

I find out rvm ruby wrapper path with command:

passenger-config --ruby-command

I took the path from the result and entered to a passenger config in nginx/passenger.conf:

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /usr/local/rvm/gems/ruby-2.3.1/wrappers/ruby;

I think you could try this:

<div [ngStyle]="{'background-image': 'url(' + photo + ')'}"></div>

From reading your ngStyle expression, I guess that you missed some "'"...

Another option would be to use join

var mystr = "Matayoshi";
mystr = ["Mariano", mystr].join(' ');

try

   git pull --rebase

The Arrays.equals(array1, array2) :

check if both arrays contain the same number of elements, and all corresponding pairs of elements in the two arrays are equal.

The array1.equals(array2) :

compare the object to another object and return true only if the reference of the two object are equal as in the Object.equals()

To follow up on malat's response, you can avoid losing changes by creating a patch and reapply it at a later time.

git diff --no-prefix > patch.txt
patch -p0 < patch.txt

Store your patch outside the repository folder for safety.

If you wrote this "getElementByClassName" then you will encounter with this error "document.getElementByClass is not a function" so to overcome that error just write "getElementsByClassName". Because it should be Elements not Element.

The issue, I think, was with a CSS library starting with comments.

While in development, I do not minify files and I don't remove comments. This meant that the stylesheet started with some comments, causing it to be seen as something different from CSS.

Removing the library and putting it into a vendor file (which is ALWAYS minified without comments) solved the issue.

Again, I'm not 100% sure this is a fix, but it's still a win for me as it works as expected now.

What about Regex.Replace solution?

myStr = Regex.Replace(myStr, "\s", "")

You can use express-error-handler to use static html pages for error handling and to avoid defining a view handler.

The error was probably caused by a 404, maybe a missing favicon (apparent if you had included the previous console message). The 'view handler' of 'html' doesn't seem to be valid in 4.x express.

Regardless of the cause, you can avoid defining a (valid) view handler as long as you modify additional elements of your configuration.

Your options are to fix this problem are:

• Define a valid view handler as in other answers
• Use send() instead of render to return the content directly

http://expressjs.com/en/api.html#res.render

Using render without a filepath automatically invokes a view handler as with the following two lines from your configuration:

res.render('404', { url: req.url });

and:

res.render('500);

Make sure you install express-error-handler with:

npm install --save express-error-handler

Then import it in your app.js

var ErrorHandler = require('express-error-handler');

Then change your error handling to use:

// define below all other routes
var errorHandler = ErrorHandler({
  static: {
    '404': 'error.html' // put this file in your Public folder
    '500': 'error.html' // ditto
});

// any unresolved requests will 404

Create "regular expression to detect empty string", and then inverse it. Invesion of regular language is the regular language. I think regular expression library in what you leverage - should support it, but if not you always can write your own library.

grep --invert-match

Use this technique to increase the speed of inserting records in Entity Framework. Here I use a simple stored procedure to insert the records. And to execute this stored procedure I use .FromSql() method of Entity Framework which executes Raw SQL.

The stored procedure code:

CREATE PROCEDURE TestProc
@FirstParam VARCHAR(50),
@SecondParam VARCHAR(50)

AS
  Insert into SomeTable(Name, Address) values(@FirstParam, @SecondParam) 
GO

Next, loop through all your 4000 records and add the Entity Framework code which executes the stored

procedure onces every 100th loop.

For this I create a string query to execute this procedure, keep on appending to it every sets of record.

Then check it the loop is running in the multiples of 100 and in that case execute it using .FromSql().

So for 4000 records I only have to execute the procedure for only 4000/100 = 40 times.

Check the below code:

string execQuery = "";
var context = new MyContext();
for (int i = 0; i < 4000; i++)
{
    execQuery += "EXEC TestProc @FirstParam = 'First'" + i + "'', @SecondParam = 'Second'" + i + "''";

    if (i % 100 == 0)
    {
        context.Student.FromSql(execQuery);
        execQuery = "";
    }
}

Using this command you can find all partitions, size & free space: wmic logicaldisk get size, freespace, caption

Do you want to order it?

Select * From temp where mydate > '2009-06-29 04:00:44' ORDER BY mydate;

The following CSS rule disables resizing behavior for textarea elements:

textarea {
  resize: none;
}

To disable it for some (but not all) textareas, there are a couple of options.

To disable a specific textarea with the name attribute set to foo (i.e., <textarea name="foo"></textarea>):

textarea[name=foo] {
  resize: none;
}

Or, using an id attribute (i.e., <textarea id="foo"></textarea>):

#foo {
  resize: none;
}

The W3C page lists possible values for resizing restrictions: none, both, horizontal, vertical, and inherit:

textarea {
  resize: vertical; /* user can resize vertically, but width is fixed */
}

Review a decent compatibility page to see what browsers currently support this feature. As Jon Hulka has commented, the dimensions can be further restrained in CSS using max-width, max-height, min-width, and min-height.

Super important to know:

This property does nothing unless the overflow property is something other than visible, which is the default for most elements. So generally to use this, you'll have to set something like overflow: scroll;

Quote by Sara Cope, http://css-tricks.com/almanac/properties/r/resize/

Technically there aren't actually any "remote" things at all¹ in your Git repo, there are just local names that should correspond to the names on another, different repo. The ones named origin/whatever will initially match up with those on the repo you cloned-from:

git clone ssh://some.where.out.there/some/path/to/repo # or git://some.where...

makes a local copy of the other repo. Along the way it notes all the branches that were there, and the commits those refer-to, and sticks those into your local repo under the names refs/remotes/origin/.

Depending on how long you go before you git fetch or equivalent to update "my copy of what's some.where.out.there", they may change their branches around, create new ones, and delete some. When you do your git fetch (or git pull which is really fetch plus merge), your repo will make copies of their new work and change all the refs/remotes/origin/<name> entries as needed. It's that moment of fetching that makes everything match up (well, that, and the initial clone, and some cases of pushing too—basically whenever Git gets a chance to check—but see caveat below).

Git normally has you refer to your own refs/heads/<name> as just <name>, and the remote ones as origin/<name>, and it all just works because it's obvious which one is which. It's sometimes possible to create your own branch names that make it not obvious, but don't worry about that until it happens. :-) Just give Git the shortest name that makes it obvious, and it will go from there: origin/master is "where master was over there last time I checked", and master is "where master is over here based on what I have been doing". Run git fetch to update Git on "where master is over there" as needed.

Caveat: in versions of Git older than 1.8.4, git fetch has some modes that don't update "where master is over there" (more precisely, modes that don't update any remote-tracking branches). Running git fetch origin, or git fetch --all, or even just git fetch, does update. Running git fetch origin master doesn't. Unfortunately, this "doesn't update" mode is triggered by ordinary git pull. (This is mainly just a minor annoyance and is fixed in Git 1.8.4 and later.)

¹Well, there is one thing that is called a "remote". But that's also local! The name origin is the thing Git calls "a remote". It's basically just a short name for the URL you used when you did the clone. It's also where the origin in origin/master comes from. The name origin/master is called a remote-tracking branch, which sometimes gets shortened to "remote branch", especially in older or more informal documentation.

You can use array_agg function for that:

SELECT "Movie",
array_to_string(array_agg(distinct "Actor"),',') AS Actor
FROM Table1
GROUP BY "Movie";

Result:

I had the same problem: the latest update failed to install because it couldn't rename the tools folder in android-sdk-windows. I'm using AVG antivirus and disabling it didn't help, but I don't think it had anything to do with the AV program anyway.

Fact is, running the Android SDK setup apparently uses items in the "android-sdk-windows\tools" directory. I'm on Win Vista x32 so maybe that causes some unique situation - I'm not sure.

Solution:

• I made a copy of the tools folder itself (keeping it at the same directory tree level, thus "tools" and "tools-copy" were both in the "android-sdk-windows" folder).

• I ran Android.bat from that copy

• I ran the update without problems (it updated the original, not-being-used-at-the-moment tools folder, among whatever other items it needed to).

• I closed the SDK, deleted the folder (I had to kill the adb.exe process first - not sure why that always persists but you can't delete the folder without doing that).

• I restarted the SDK from the normal (now-updated) tools folder. Worked like a charm!

Note that simply killing adb.exe was NOT sufficient to get around the original issue... only by copying the tools folder and using the copy to run Android for the duration of the update process was enough to rectify the problem.

I hope this helps others... it's quite vexing to have to spend time resolving basic issues like this just to run an update.

For me (in Angular project) this code helped:

In HTML you should add autoplay muted

In JS/TS

playVideo() {
    const media = this.videoplayer.nativeElement;
    media.muted = true; // without this line it's not working although I have "muted" in HTML
    media.play();
}

They're just trawling lists of web sites, and recording the resulting IP addresses in a database.

All you're seeing is the reverse mapping of that list. It's not guaranteed to be a full list (indeed more often than not it won't be) because it's impossible to learn every possible web site address.

 render() {
    var myloop = [];

    for (let i = 0; i < 10; i++) {
      myloop.push(
        <View key={i}>
        <Text style={{ textAlign: 'center', marginTop: 5 }} >{i}</Text>
        </View>
      );
    }

     return (

            <View >
              <Text >Welcome to React Native!</Text>
               {myloop}
            </View>


        );
      }

Output 1 2 3 4 5 6 7 8 9

I am sure there must be a way of doing this without writing my own CSS, its crazy I have to overwrite the margin and padding, all I wanted was a 2 column grid.

.row-offset-0 {
    margin-left: 0;
    margin-right: 0;
}
.row-offset-0 > * {
    padding-left: 0;
    padding-right: 0;
}

There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.

You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.

When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.

I had this issue myself, and I wanted to both be able to set the width, and have it update on rotate and allow the user to scale and zoom the page (the current answer provides the first but prevents the later as a side-effect).. so I came up with a fix that keeps the view width correct for the orientation, but still allows for zooming, though it is not super straight forward.

First, add the following Javascript to the webpage you are displaying:

 <script type='text/javascript'>
 function setViewPortWidth(width) {
  var metatags = document.getElementsByTagName('meta');
  for(cnt = 0; cnt < metatags.length; cnt++) { 
   var element = metatags[cnt];
   if(element.getAttribute('name') == 'viewport') {

    element.setAttribute('content','width = '+width+'; maximum-scale = 5; user-scalable = yes');
    document.body.style['max-width'] = width+'px';
   }
  }
 }
 </script>

Then in your - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation method, add:

float availableWidth = [EmailVC webViewWidth];
NSString *stringJS;

stringJS = [NSString stringWithFormat:@"document.body.offsetWidth"];
float documentWidth = [[_webView stringByEvaluatingJavaScriptFromString:stringJS] floatValue];

if(documentWidth > availableWidth) return; // Don't perform if the document width is larger then available (allow auto-scale)

// Function setViewPortWidth defined in EmailBodyProtocolHandler prepend
stringJS = [NSString stringWithFormat:@"setViewPortWidth(%f);",availableWidth];
[_webView stringByEvaluatingJavaScriptFromString:stringJS];

Additional Tweaking can be done by modifying more of the viewportal content settings:

http://www.htmlgoodies.com/beyond/webmaster/toolbox/article.php/3889591/Detect-and-Set-the-iPhone--iPads-Viewport-Orientation-Using-JavaScript-CSS-and-Meta-Tags.htm

Also, I understand you can put a JS listener for onresize or something like to trigger the rescaling, but this worked for me as I'm doing it from Cocoa Touch UI frameworks.

Hope this helps someone :)

Here is a prototype to convert a number to a readable string respecting the new international standards.

There are two ways to represent big numbers: You could either display them in multiples of 1000 = 10 3 (base 10) or 1024 = 2 10 (base 2). If you divide by 1000, you probably use the SI prefix names, if you divide by 1024, you probably use the IEC prefix names. The problem starts with dividing by 1024. Many applications use the SI prefix names for it and some use the IEC prefix names. The current situation is a mess. If you see SI prefix names you do not know whether the number is divided by 1000 or 1024

https://wiki.ubuntu.com/UnitsPolicy

http://en.wikipedia.org/wiki/Template:Quantities_of_bytes

Object.defineProperty(Number.prototype,'fileSize',{value:function(a,b,c,d){
 return (a=a?[1e3,'k','B']:[1024,'K','iB'],b=Math,c=b.log,
 d=c(this)/c(a[0])|0,this/b.pow(a[0],d)).toFixed(2)
 +' '+(d?(a[1]+'MGTPEZY')[--d]+a[2]:'Bytes');
},writable:false,enumerable:false});

This function contains no loop, and so it's probably faster than some other functions.

Usage:

IEC prefix

console.log((186457865).fileSize()); // default IEC (power 1024)
//177.82 MiB
//KiB,MiB,GiB,TiB,PiB,EiB,ZiB,YiB

SI prefix

console.log((186457865).fileSize(1)); //1,true for SI (power 1000)
//186.46 MB 
//kB,MB,GB,TB,PB,EB,ZB,YB

i set the IEC as default because i always used binary mode to calculate the size of a file... using the power of 1024

If you just want one of them in a short oneliner function:

SI

function fileSizeSI(a,b,c,d,e){
 return (b=Math,c=b.log,d=1e3,e=c(a)/c(d)|0,a/b.pow(d,e)).toFixed(2)
 +' '+(e?'kMGTPEZY'[--e]+'B':'Bytes')
}
//kB,MB,GB,TB,PB,EB,ZB,YB

IEC

function fileSizeIEC(a,b,c,d,e){
 return (b=Math,c=b.log,d=1024,e=c(a)/c(d)|0,a/b.pow(d,e)).toFixed(2)
 +' '+(e?'KMGTPEZY'[--e]+'iB':'Bytes')
}
//KiB,MiB,GiB,TiB,PiB,EiB,ZiB,YiB

Usage:

console.log(fileSizeIEC(7412834521));

if you have some questions about the functions just ask

I hypothesize that given an element where all of its children are ordered on the document sequentially, the fastest way should be to do a binary search, comparing the document positions of the elements. However, as introduced in the conclusion the hypothesis is rejected. The more elements you have, the greater the potential for performance. For example, if you had 256 elements, then (optimally) you would only need to check just 16 of them! For 65536, only 256! The performance grows to the power of 2! See more numbers/statistics. Visit Wikipedia

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndex', {
      get: function() {
        var searchParent = this.parentElement;
        if (!searchParent) return -1;
        var searchArray = searchParent.children,
            thisOffset = this.offsetTop,
            stop = searchArray.length,
            p = 0,
            delta = 0;
        
        while (searchArray[p] !== this) {
            if (searchArray[p] > this)
                stop = p + 1, p -= delta;
            delta = (stop - p) >>> 1;
            p += delta;
        }
        
        return p;
      }
    });
})(window.Element || Node);

Then, the way that you use it is by getting the 'parentIndex' property of any element. For example, check out the following demo.

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndex', {
      get: function() {
        var searchParent = this.parentNode;
        if (searchParent === null) return -1;
        var childElements = searchParent.children,
            lo = -1, mi, hi = childElements.length;
        while (1 + lo !== hi) {
            mi = (hi + lo) >> 1;
            if (!(this.compareDocumentPosition(childElements[mi]) & 0x2)) {
                hi = mi;
                continue;
            }
            lo = mi;
        }
        return childElements[hi] === this ? hi : -1;
      }
    });
})(window.Element || Node);

output.textContent = document.body.parentIndex;
output2.textContent = document.documentElement.parentIndex;

Body parentIndex is <b id="output"></b><br />
documentElements parentIndex is <b id="output2"></b>

Limitations

• This implementation of the solution will not work in IE8 and below.

Binary VS Linear Search On 200,000 elements (might crash some mobile browsers, BEWARE!):

• In this test, we will see how long it takes for a linear search to find the middle element VS a binary search. Why the middle element? Because it is at the average location of all the other locations, so it best represents all of the possible locations.

Binary Search

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndexBinarySearch', {
      get: function() {
        var searchParent = this.parentNode;
        if (searchParent === null) return -1;
        var childElements = searchParent.children,
            lo = -1, mi, hi = childElements.length;
        while (1 + lo !== hi) {
            mi = (hi + lo) >> 1;
            if (!(this.compareDocumentPosition(childElements[mi]) & 0x2)) {
                hi = mi;
                continue;
            }
            lo = mi;
        }
        return childElements[hi] === this ? hi : -1;
      }
    });
})(window.Element || Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var child=test.children.item(99.9e+3);
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=200 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99.9e+3+i+Math.random())).parentIndexBinarySearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the binary search ' + ((end-start)*10).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
}, 125);

Backwards (`lastIndexOf`) Linear Search

(function(t){"use strict";var e=Array.prototype.lastIndexOf;Object.defineProperty(t.prototype,"parentIndexLinearSearch",{get:function(){return e.call(t,this)}})})(window.Element||Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:

  for (var i=2000 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99e+3+i+Math.random())).parentIndexLinearSearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the backwards linear search ' + (end-start).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden;white-space:pre></div>

Forwards (`indexOf`) Linear Search

(function(t){"use strict";var e=Array.prototype.indexOf;Object.defineProperty(t.prototype,"parentIndexLinearSearch",{get:function(){return e.call(t,this)}})})(window.Element||Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);

  for (var i=2000 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99e+3+i+Math.random())).parentIndexLinearSearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the forwards linear search ' + (end-start).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden;white-space:pre></div>

PreviousElementSibling Counter Search

Counts the number of PreviousElementSiblings to get the parentIndex.

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndexSiblingSearch', {
      get: function() {
        var i = 0, cur = this;
        do {
            cur = cur.previousElementSibling;
            ++i;
        } while (cur !== null)
        return i; //Returns 3
      }
    });
})(window.Element || Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var child=test.children.item(99.95e+3);
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=100 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99.95e+3+i+Math.random())).parentIndexSiblingSearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the PreviousElementSibling search ' + ((end-start)*20).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden;white-space:pre></div>

No Search

For benchmarking what the result of the test would be if the browser optimized out the searching.

test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=2000 + end; i-- !== end; )
    console.assert( true );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the no search ' + (end-start).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden></div>

The Conculsion

However, after viewing the results in Chrome, the results are the opposite of what was expected. The dumber forwards linear search was a surprising 187 ms, 3850%, faster than the binary search. Evidently, Chrome somehow magically outsmarted the console.assert and optimized it away, or (more optimistically) Chrome internally uses numerical indexing system for the DOM, and this internal indexing system is exposed through the optimizations applied to Array.prototype.indexOf when used on a HTMLCollection object.

You need to manually create the bundle for a debug build.

Bundle debug build:

#React-Native 0.59
react-native bundle --dev false --platform android --entry-file index.js --bundle-output ./android/app/src/main/assets/index.android.bundle --assets-dest ./android/app/src/main/res

#React-Native 0.49.0+
react-native bundle --dev false --platform android --entry-file index.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug

#React-Native 0-0.49.0
react-native bundle --dev false --platform android --entry-file index.android.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug

Then to build the APK's after bundling:

$ cd android
#Create debug build:
$ ./gradlew assembleDebug
#Create release build:
$ ./gradlew assembleRelease #Generated `apk` will be located at `android/app/build/outputs/apk`

P.S. Another approach might be to modify gradle scripts.

CSS rules are inherited by default - hence the "cascading" name. To get what you want you need to use !important:

form div
{
    font-size: 12px;
    font-weight: bold;
}

div.content
{
    // any rule you want here, followed by !important
}

mvn clean install -U

-U means force update of dependencies.

Also, if you want to import the project into eclipse, I first run:

mvn eclipse:eclipse

then run

mvn eclipse:clean

I fixed my git error: object file is empty by:

1. Saving a copy of all files that I edited since my last successful commit/push,
2. Removing and re-cloning my repository,
3. Replacing the old files with my edited files.

Hopes this helps.

If you want to ignore the step to check if file exists or not, then you can use a fairly easy command, which will delete the file if exists and does not throw an error if it is non-existing.

 rm -f xyz.csv

Sending data from Activity into Fragments linked by XML

If you create a fragment in Android Studio using one of the templates e.g. File > New > Fragment > Fragment (List), then the fragment is linked via XML. The newInstance method is created in the fragment but is never called so can't be used to pass arguments.

Instead in the Activity override the method onAttachFragment

@Override
public void onAttachFragment(Fragment fragment) {
    if (fragment instanceof DetailsFragment) {
        Bundle args = new Bundle();
        args.putInt("index", index);
        f.setArguments(args);        
     }
}

Then read the arguments in the fragment onCreate method as per the other answers

Declare you integer variable as nullable eg: int? variable=0; variable=null;

I too had the same issue. I changed the codec to H264-MPEG-4 AVC and the videos started working in HTML5/Chrome.

Option selected in converter: H264-MPEG-4 AVC, Codec visible in VLC player: H264-MPEG-4 AVC (part 10) (avc1)

Hope it helps...

Here's another method if you can safely use CSS3's transform property:

.fixed-horizontal-center
{
    position: fixed;
    top: 100px; /* or whatever top you need */
    left: 50%;
    width: auto;
    -webkit-transform: translateX(-50%);
    -moz-transform: translateX(-50%);
    -ms-transform: translateX(-50%);
    -o-transform: translateX(-50%);
    transform: translateX(-50%);
}

...or if you want both horizontal AND vertical centering:

.fixed-center
{
    position: fixed;
    top: 50%;
    left: 50%;
    width: auto;
    height: auto;
    -webkit-transform: translate(-50%,-50%);
    -moz-transform: translate(-50%,-50%);
    -ms-transform: translate(-50%,-50%);
    -o-transform: translate(-50%,-50%);
    transform: translate(-50%,-50%);
}

In Swift 4.2, Create it via @IBDesignable like this:

@IBDesignable

class DesignableViewCustomCorner: UIView {

    @IBInspectable var cornerRadious: CGFloat = 0 {
        didSet {
            let path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: [.topLeft, .topRight], cornerRadii: CGSize(width: cornerRadious, height: cornerRadious))
            let mask = CAShapeLayer()
            mask.path = path.cgPath
            self.layer.mask = mask
        }
    }

}

List<T> has a Reverse() method, however it only reverses the order of two (or more) consecutive items.

your_list.Reverse(index, 2);

Where the second parameter 2 indicates we are reversing the order of 2 items, starting with the item at the given index.

It depends. The System.Timers.Timer has two modes of operation.

If SynchronizingObject is set to an ISynchronizeInvoke instance then the Elapsed event will execute on the thread hosting the synchronizing object. Usually these ISynchronizeInvoke instances are none other than plain old Control and Form instances that we are all familiar with. So in that case the Elapsed event is invoked on the UI thread and it behaves similar to the System.Windows.Forms.Timer. Otherwise, it really depends on the specific ISynchronizeInvoke instance that was used.

If SynchronizingObject is null then the Elapsed event is invoked on a ThreadPool thread and it behaves similar to the System.Threading.Timer. In fact, it actually uses a System.Threading.Timer behind the scenes and does the marshaling operation after it receives the timer callback if needed.

I am not sure about gson but this is how you do it with Jon.sample hope there must be similar way using gson

y = String.Join(" ", fooArray);
string[] target = { "Hi", "World", "VW_Slep" };

for (int i = 0; i < target.Length; i++)
{
    string v = target[i];

}

There is not a really pythonic way of repeating something. However, it is a better way:

map(lambda index:do_something(), xrange(10))

If you need to pass the index then:

map(lambda index:do_something(index), xrange(10))

Consider that it returns the results as a collection. So, if you need to collect the results it can help.

This error is often caused by incompatible jQuery versions. I encountered the same error with a foundation 6 repository. My repository was using jQuery 3, but foundation requires an earlier version. I then changed it and it worked.

If you look at the version of jQuery required by the foundation 5 dependencies it states "jquery": "~2.1.0".

Can you confirm that you are loading the correct version of jQuery?

I hope this helps.

Also you can position the other window before withdrawing it so that you position your message

#!/usr/bin/env python

from Tkinter import *
import tkMessageBox

window = Tk()
window.wm_withdraw()

#message at x:200,y:200
window.geometry("1x1+200+200")#remember its .geometry("WidthxHeight(+or-)X(+or-)Y")
tkMessageBox.showerror(title="error",message="Error Message",parent=window)

#centre screen message
window.geometry("1x1+"+str(window.winfo_screenwidth()/2)+"+"+str(window.winfo_screenheight()/2))
tkMessageBox.showinfo(title="Greetings", message="Hello World!")

Just close the Eclipse or STS and restart it again. This may fix this error.

There's nothing on the Documentation that mentions about anything like that.

Here's a quote:

-Dproperty=value Set a system property value. If value is a string that contains spaces, you must enclose the string in double quotes:

java -Dfoo="some string" SomeClass

if (n === Object(n)) {
   // code
}

I tested this code based on all the comments above. Seems to work flawlessly. Comments?

Sub ResetImmediate()  
        Debug.Print String(5, "*") & " Hi there mom. " & String(5, "*") & vbTab & "Smile"  
        Application.VBE.Windows("Immediate").SetFocus  
        Application.SendKeys "^g ^a {DEL} {HOME}"  
        DoEvents  
        Debug.Print "Bye Mom!"  
End Sub

Previously used the Debug.Print String(200, chr(10)) which takes advantage of the Buffer overflow limit of 200 lines. Didn't like this method much but it works.

Set sh1 = Worksheets(filenum(lngPosition)).Activate

You are getting Subscript out of range error error becuase it cannot find that Worksheet.

Also please... please... please do not use .Select/.Activate/Selection/ActiveCell You might want to see How to Avoid using Select in Excel VBA Macros.

Example taken from W3Schools: PHP Select Data from MySQL

<?php
$con=mysqli_connect("example.com","peter","abc123","my_db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$result = mysqli_query($con,"SELECT * FROM Persons");

echo "<table border='1'>
<tr>
<th>Firstname</th>
<th>Lastname</th>
</tr>";

while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['FirstName'] . "</td>";
echo "<td>" . $row['LastName'] . "</td>";
echo "</tr>";
}
echo "</table>";

mysqli_close($con);
?>

It's a good place to learn from!

Could use sprintf to accomplish this:

awk '{str = sprintf("%s %s", $1, $2)} END {print str}' file

In SQL Server 2017 STRING_AGG is added:

SELECT t.name,STRING_AGG (c.name, ',') AS csv
FROM sys.tables t
JOIN sys.columns c on t.object_id = c.object_id
GROUP BY t.name
ORDER BY 1

Also, STRING_SPLIT is usefull for the opposite case and available in SQL Server 2016

I found the solution for this problem:

1. Go to the Server Properties.
2. Select the Connections tab.
3. Check if the ansi_padding option is unchecked.

You need it to install development iPhone applications on development devices.

So why don't you simply use a key-value literal?

var params = {
    'slide0001.html': 'Looking Ahead',
    'slide0002.html': 'Forecase',
    ...
};

return params['slide0001.html']; // returns: Looking Ahead

For me, the issue was that I have an angular project folder inside a rails project folder, and I ran all the angular update commands in the rails parent folder rather than the actual angular folder.

Sometimes using   instead of spaces will work. Clearly it has drawbacks, though.

I ended up packaging this into an extension method so (1) I could generate the label and radio at once and (2) so I didn't have to fuss with specifying my own IDs:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString RadioButtonAndLabelFor<TModel, TProperty>(this HtmlHelper<TModel> self, Expression<Func<TModel, TProperty>> expression, bool value, string labelText)
    {
        // Retrieve the qualified model identifier
        string name = ExpressionHelper.GetExpressionText(expression);
        string fullName = self.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(name);

        // Generate the base ID
        TagBuilder tagBuilder = new TagBuilder("input");
        tagBuilder.GenerateId(fullName);
        string idAttr = tagBuilder.Attributes["id"];

        // Create an ID specific to the boolean direction
        idAttr = String.Format("{0}_{1}", idAttr, value);

        // Create the individual HTML elements, using the generated ID
        MvcHtmlString radioButton = self.RadioButtonFor(expression, value, new { id = idAttr });
        MvcHtmlString label = self.Label(idAttr, labelText);

        return new MvcHtmlString(radioButton.ToHtmlString() + label.ToHtmlString());
    }
}

Usage:

@Html.RadioButtonAndLabelFor(m => m.IsMarried, true, "Yes, I am married")

A zombie is already dead, so you cannot kill it. To clean up a zombie, it must be waited on by its parent, so killing the parent should work to eliminate the zombie. (After the parent dies, the zombie will be inherited by pid 1, which will wait on it and clear its entry in the process table.) If your daemon is spawning children that become zombies, you have a bug. Your daemon should notice when its children die and wait on them to determine their exit status.

An example of how you might send a signal to every process that is the parent of a zombie (note that this is extremely crude and might kill processes that you do not intend. I do not recommend using this sort of sledge hammer):

# Don't do this.  Incredibly risky sledge hammer!
kill $(ps -A -ostat,ppid | awk '/[zZ]/ && !a[$2]++ {print $2}')

As you are using C++, the obligatory suggestion that's still missing here, is to use std::vector<double>.

You can easily pass it by reference:

void foo(std::vector<double>& bar) {}

And if you have C++11 support, also have a look at std::array.

For reference:

Following Joe Shaw's answer about multi-threaded code not to work as expected, I figured that the runcall method in cProfile is merely doing self.enable() and self.disable() calls around the profiled function call, so you can simply do that yourself and have whatever code you want in-between with minimal interference with existing code.
