For anybody facing a similar issue at this point in time, all you need to do is update your Android Studio to the latest version

I'm on Android Studio 3.1 Build #AI-173.4670197, built on March 22, 2018 JRE: 1.8.0_152-release-1024-b02 amd64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o Windows 10 10.

I had the same issue and it only worked after changing my build.grade file to

    compileOptions {                                                          
    sourceCompatibility JavaVersion.VERSION_1_8 
    targetCompatibility JavaVersion.VERSION_1_8


}

Prior to this change nothing worked and all compiles would fail. previously my settings were

sourceCompatibility JavaVersion.VERSION_1_7 
targetCompatibility JavaVersion.VERSION_1_8

For me, I got this error while working on some Udacity projects. I fixed it by adding the following code to the top-level build.gradle file.

allprojects {
    String osName = System.getProperty("os.name").toLowerCase()
    if (osName.contains("windows")) {
        buildDir = "C:/tmp/${rootProject.name}/${project.name}"
    }
    repositories {
        jcenter()
        google()
    }
}

in my case I accidentally changed version="1.0" to xml version="1.0" in my XML file.

I only had to change it back.

if you have the same problem and the solutions above didn't work for you. open Gradle Console and scroll to Run with --debug option click it and it will show you more useful info about your error.

some notes:

this error doesn't appear directly after I make the change in XML it appear only after I change some java code. I think it has something to do with the instant run and build cash.

I have just written this code into gradle.properties and it is ok now

org.gradle.jvmargs=-XX:MaxHeapSize\=2048m -Xmx2048m

I had c++ codes in my project but i didn't have NDK installed, installing it solved the problem

I use @Test annotiation of org.junit.Test package, but I had the same problem. After adding testImplementation("org.assertj:assertj-core:3.10.0") on build.gradle, it worked.

python supports arbitrarily large integers naturally:

In [1]: 59**3*61**4*2*3*5*7*3*5*7
Out[1]: 62702371781194950
In [2]: _ % 61**4
Out[2]: 0

Simple and fast since a 1d array is essentially a vector

vector <- array[1:length(array)]

A inner join only shows rows if there is a matching record on the other (right) side of the join.

A (left) outer join shows rows for each record on the left hand side, even if there are no matching rows on the other (right) side of the join. If there is no matching row, the columns for the other (right) side would show NULLs.

class Test {
    public function yo() {
        return 'yoes';
    }
}

$var = 'Test';

$obj = new $var();
echo $obj->yo(); //yoes

Using ex/vi editor and globstar option (syntax similar to awk and sed):

ex +"/string1/,/string3/p" -R -scq! file.txt

where aaa is your starting point, and bbb is your ending text.

To search recursively, try:

ex +"/aaa/,/bbb/p" -scq! **/*.py

^{Note: To enable ** syntax, run shopt -s globstar (Bash 4 or zsh).}

Here are conversion method for both ways. this = instance of your class

public string ToXML()
    {
        using(var stringwriter = new System.IO.StringWriter())
        { 
            var serializer = new XmlSerializer(this.GetType());
            serializer.Serialize(stringwriter, this);
            return stringwriter.ToString();
        }
    }

 public static YourClass LoadFromXMLString(string xmlText)
    {
        using(var stringReader = new System.IO.StringReader(xmlText))
        {
            var serializer = new XmlSerializer(typeof(YourClass ));
            return serializer.Deserialize(stringReader) as YourClass ;
        }

Works in git 2.28

git clone --filter=blob:none --no-checkout --depth 1 --sparse <project-url>
cd <project>
git sparse-checkout init --cone

Specify the files and folders you want to clone

git sparse-checkout add <folder>/<innerfolder> <folder2>/<innerfolder2>
git checkout

Looping over arrays and objects is a pretty common task, and it's good that you're wanting to learn how to do it. Generally speaking you can do a foreach loop which cycles over each member, assigning it a new temporary name, and then lets you handle that particular member via that name:

foreach ($arr as $item) {
    echo $item->sm_id;
}

In this example each of our values in the $arr will be accessed in order as $item. So we can print our values directly off of that. We could also include the index if we wanted:

foreach ($arr as $index => $item) {
    echo "Item at index {$index} has sm_id value {$item->sm_id}";
}

I've figured out how to work around this issue without mixing parent and sub scope data. Set a ng-if on the the ng-include element and set it to a scope variable. For example :

<div ng-include="{{ template }}" ng-if="show"/>

In your controller, when you have set all the data you need in your sub scope, then set show to true. The ng-include will copy at this moment the data set in your scope and set it in your sub scope.

The rule of thumb is to reduce scope data deeper the scope are, else you have this situation.

Max

This creates dictionary of text (string):

Map<String, String> dictionary = new HashMap<String, String>();

you then use it as a:

dictionary.put("key", "value");
String value = dictionary.get("key");

Works but gives an error you need to keep the constructor class same as the declaration class. I know it inherits from the parent class but, unfortunately it gives an error on runtime.

Map<String, String> dictionary = new Map<String, String>();

This works properly.

You can clear DataGridView in this manner

dataGridView1.Rows.Clear();
dataGridView1.Refresh();

If it is databound then try this

dataGridView1.Rows.Clear() // If dgv is bound to datatable
dataGridView1.DataBind();

import re
abc = "askhnl#$%askdjalsdk"
ddd = abc.replace("#$%","")
print (ddd)

and you shall see your result as

'askhnlaskdjalsdk

You can use a plain old C array:

NSInteger myIntegers[40];

for (NSInteger i = 0; i < 40; i++)
    myIntegers[i] = i;

// to get one of them
NSLog (@"The 4th integer is: %d", myIntegers[3]);

Or, you can use an NSArray or NSMutableArray, but here you will need to wrap up each integer inside an NSNumber instance (because NSArray objects are designed to hold class instances).

NSMutableArray *myIntegers = [NSMutableArray array];

for (NSInteger i = 0; i < 40; i++)
    [myIntegers addObject:[NSNumber numberWithInteger:i]];

// to get one of them
NSLog (@"The 4th integer is: %@", [myIntegers objectAtIndex:3]);

// or
NSLog (@"The 4th integer is: %d", [[myIntegers objectAtIndex:3] integerValue]);

If you're using the new emulator that comes with Android Studio 2.0, the keyboard shortcut for the menu key is now Cmd+M, just like in Genymotion.

Alternatively, you can always send a menu button press using adb in a terminal:

adb shell input keyevent KEYCODE_MENU

Also note that the menu button shortcut isn't a strict requirement, it's just the default behavior provided by the ReactActivity Java class (which is used by default if you created your project with react-native init). Here's the relevant code from onKeyUp in ReactActivity.java:

if (keyCode == KeyEvent.KEYCODE_MENU) {
  mReactInstanceManager.showDevOptionsDialog();
  return true;
}

If you're adding React Native to an existing app (documentation here) and you aren't using ReactActivity, you'll need to hook the menu button up in a similar way. You can also call ReactInstanceManager.showDevOptionsDialog through any other mechanism. For example, in an app I'm working on, I added a dev-only Action Bar menu item that brings up the menu, since I find that more convenient than shaking the device when working on a physical device.

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

I've done this with PDFBox. I suppose it works similarly to iTextSharp.

After trying the above suggestions, the only thing that worked for me was changing the border attribute to "0" in the following sections of a child theme's style.css (do a "Find" operation to locate each one -- the following are just snippets):

.comment-content table {
    border-bottom: 1px solid #ddd;

.comment-content td {
    border-top: 1px solid #ddd;
    padding: 6px 10px 6px 0;
}

Thus looking like this afterwards:

.comment-content table {
    border-bottom: 0;

.comment-content td {
    border-top: 0;
    padding: 6px 10px 6px 0;
}

a slightly modified version of the deque window, to make it a true rolling window. So that it starts being populated with just one element, then grows to it's maximum window size, and then shrinks as it's left edge comes near the end:

from collections import deque
def window(seq, n=2):
    it = iter(seq)
    win = deque((next(it, None) for _ in xrange(1)), maxlen=n)
    yield win
    append = win.append
    for e in it:
        append(e)
        yield win
    for _ in xrange(len(win)-1):
        win.popleft()
        yield win

for wnd in window(range(5), n=3):
    print(list(wnd))

this gives

[0]
[0, 1]
[0, 1, 2]
[1, 2, 3]
[2, 3, 4]
[3, 4]
[4]

Counting the number of lines can be done by following codes:

<?php
$fp= fopen("myfile.txt", "r");
$count=0;
while($line = fgetss($fp)) // fgetss() is used to get a line from a file ignoring html tags
$count++;
echo "Total number of lines  are ".$count;
fclose($fp);
?>

You can use std::numeric_limits which is defined in <limits> to find the minimum or maximum value of types (As long as a specialization exists for the type). You can also use it to retrieve infinity (and put a - in front for negative infinity).

#include <limits>

//...

std::numeric_limits<float>::max();
std::numeric_limits<float>::min();
std::numeric_limits<float>::infinity();

As noted in the comments, min() returns the lowest possible positive value. In other words the positive value closest to 0 that can be represented. The lowest possible value is the negative of the maximum possible value.

There is of course the std::max_element and min_element functions (defined in <algorithm>) which may be a better choice for finding the largest or smallest value in an array.

I think you have a conceptual problem here. To say "I tried set height:100% on iframe, the result is quite close but the iframe tried to fill the whole page", well, when has "100%" not been equal to "whole"?

You have asked the iframe to fill the entire height of its container (which is the body) but unfortunately it has a block level sibling in the <div> above which you've asked to be 30px big. So the parent container total is now being asked to size to 100% + 30px > 100%! Hence scrollbars.

What I think you mean is that you would like the iframe to consume what's left like frames and table cells can, i.e. height="*". IIRC this doesn't exist.

Unfortunately to the best of my knowledge there is no way to effectively mix/calculate/subtract absolute and relative units either, so I think you're reduced to two options:

1. Absolutely position your div, which will take it out of the container so the iframe alone will consume it's containers height. This leaves you with all manner of other problems though, but perhaps for what you're doing opacity or alignment would be ok.

2. Alternatively you need to specify a % height for the div and reduce the height of the iframe by that much. If the absolute height is really that important you'll need to apply that to a child element of the div instead.

Here's how it should look like in order to return a simple Yes when it's checked.

<input type="checkbox" id="newsletter" name="newsletter" value="Yes" checked>
<label for="newsletter">i want to sign up for newsletter</label>

I also added the text as a label, it means you can click the text as well to check the box. Small but, personally I hate when sites make me aim my mouse at this tiny little check box.

When the form is submitted if the check box is checked $_POST['newsletter'] will equal Yes. Just how you are checking to see if $_POST['name'],$_POST['email'], and $_POST['tel'] are empty you could do the same.

Here is an example of how you would add this into your email on the php side:

Underneath your existing code:

$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];

Add:

$newsletter = $_POST['newsletter'];
if ($newsletter != 'Yes') {
    $newsletter = 'No';
}

If the check box is checked it will add Yes in your email if it was not checked it will add No.

You need to specify it on the methods that can throw the exceptions. You just seperate them with a ',' if it can throw more than 1 type of exception. e.g.

public interface MyInterface {
  public MyObject find(int x) throws MyExceptionA,MyExceptionB;
}

This worked for me:

cd existing_folder
git init
git remote add origin path_to_your_repo.git
git add .
git commit
git push -u origin master

I am not sure if I am missing here, but I think the easiest and best way to do it is using tf.keras.backend.get_value API.

print(product)
>>tf.Tensor([[12.]], shape=(1, 1), dtype=float32)
print(tf.keras.backend.get_value(product))
>>[[12.]]

I prefer using standard converters:

#include <codecvt>

std::string s = "Hi";
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> converter;
std::wstring wide = converter.from_bytes(s);
LPCWSTR result = wide.c_str();

Please find more details in this answer: https://stackoverflow.com/a/18597384/592651

Update 12/21/2020 : My answer was commented on by @Andreas H . I thought his comment is valuable, so I updated my answer accordingly:

1. codecvt_utf8_utf16 is deprecated in C++17.
2. Also the code implies that source encoding is UTF-8 which it usually isn't.
3. In C++20 there is a separate type std::u8string for UTF-8 because of that.

But it worked for me because I am still using an old version of C++ and it happened that my source encoding was UTF-8 .

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.

Example:

<div class="editor-field">
    <%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
    <%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>

Here's a more specific example:

I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).

I made the following model:

namespace DeleteMeQuestion.Models
{
    public class QuizModel
    {
        public int ParentQuestionId { get; set; }
        public int QuestionId { get; set; }
        public string QuestionDisplayText { get; set; }
        public List<Response> Responses { get; set; }

        [Range(1,999, ErrorMessage = "Please choose a response.")]
        public int SelectedResponse { get; set; }
    }

    public class Response
    {
        public int ResponseId { get; set; }
        public int ChildQuestionId { get; set; }
        public string ResponseDisplayText { get; set; }
    }
}

There's a simple range validator in the model, just for fun. Next up, I made the following controller:

namespace DeleteMeQuestion.Controllers
{
    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index(int? id)
        {
            // TODO: get question to show based on method parameter 
            var model = GetModel(id);
            return View(model);
        }

        [HttpPost]
        public ActionResult Index(int? id, QuizModel model)
        {
            if (!ModelState.IsValid)
            {
                var freshModel = GetModel(id);
                return View(freshModel);
            }

            // TODO: save selected answer in database
            // TODO: get next question based on selected answer (hard coded to 999 for now)

            var nextQuestionId = 999;
            return RedirectToAction("Index", "Home", new {id = nextQuestionId});
        }

        private QuizModel GetModel(int? questionId)
        {
            // just a stub, in lieu of a database

            var model = new QuizModel
            {
                QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
                QuestionId = 1,
                Responses = new List<Response>
                                                {
                                                    new Response
                                                        {
                                                            ChildQuestionId = 2,
                                                            ResponseId = 1,
                                                            ResponseDisplayText = "Red"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 3,
                                                            ResponseId = 2,
                                                            ResponseDisplayText = "Blue"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 4,
                                                            ResponseId = 3,
                                                            ResponseDisplayText = "Green"
                                                        },
                                                }
            };

            return model;
        }
    }
}

Finally, I made the following view that makes use of the model:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>

<asp:Content ContentPlaceHolderID="TitleContent" runat="server">
    Home Page
</asp:Content>

<asp:Content ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm()) { %>

        <div>

            <h1><%: Model.QuestionDisplayText %></h1>

            <div>
            <ul>
            <% foreach (var item in Model.Responses) { %>
                <li>
                    <%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
                    <label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
                </li>
            <% } %>
            </ul>

            <%= Html.ValidationMessageFor(m => m.SelectedResponse) %>

        </div>

        <input type="submit" value="Submit" />

    <% } %>

</asp:Content>

As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.

This gives you the radio buttons with the same name attribute, but different ID attributes.

Some DBMSs support the FROM (SELECT ...) AS alias_name syntax.

Think of your two original queries as temporary tables. You can query them like so:

SELECT t1.Activity, t1."Total Amount 2009", t2."Total Amount 2008"
FROM (query1) as t1, (query2) as t2
WHERE t1.Activity = t2.Activity

You can do

$('.page-address-edit').addClass('test1 test2');

More here:

More than one class may be added at a time, separated by a space, to the set of matched elements, like so:

$("p").addClass("myClass yourClass");

Before proceeding:

• Install a proper mergetool. On Linux, I strongly suggest you to use meld:

  sudo apt-get install meld
  

• Configure your mergetool:

  git config --global merge.tool meld
  

Then, iterate in the following way:

git cherry-pick ....
git mergetool
git cherry-pick --continue

You have to implement KeyListener,take a look here: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

More details on how to use it: http://docs.oracle.com/javase/tutorial/uiswing/events/keylistener.html

I'm not sure but:

• If you call the delete method with a non transient object, this means first fetched the object from the DB. So it is normal to see a select statement. Perhaps in the end you see 2 select + 1 delete?

• If you call the delete method with a transient object, then it is possible that you have a cascade="delete" or something similar which requires to retrieve first the object so that "nested actions" can be performed if it is required.

Edit: Calling delete() with a transient instance means doing something like that:

MyEntity entity = new MyEntity();
entity.setId(1234);
session.delete(entity);

This will delete the row with id 1234, even if the object is a simple pojo not retrieved by Hibernate, not present in its session cache, not managed at all by Hibernate.

If you have an entity association Hibernate probably have to fetch the full entity so that it knows if the delete should be cascaded to associated entities.

If the request was sent with HTTPS you will have a extra parameter in the $_SERVER superglobal - $_SERVER['HTTPS']. You can check if it is set or not

if( isset($_SERVER['HTTPS'] ) ) {

I had the same problem after updating my AjaxControlToolkit.dll to the latest version 4.1.7.725 from 4.1.60623.0. I've searched and came up to this page, but none of the answers help me. After looking to the sample website of the Ajax Control Toolkit that is in the CodePlex zip file, I have realized that the <asp:ScriptManager> replaced by the new <ajaxtoolkit:ToolkitScriptManager>. I did so and there is no Sys.Extended is undefined any more.

Improving on Andru's idea, you can write a script which creates console functions if they don't exist:

if (!window.console) console = {};
console.log = console.log || function(){};
console.warn = console.warn || function(){};
console.error = console.error || function(){};
console.info = console.info || function(){};

Then, use any of the following:

console.log(...);
console.error(...);
console.info(...);
console.warn(...);

These functions will log different types of items (which can be filtered based on log, info, error or warn) and will not cause errors when console is not available. These functions will work in Firebug and Chrome consoles.

We can easily get the millisecond offset of a TimeZone with only a TimeZone instance and System.currentTimeMillis(). Then we can convert from milliseconds to any time unit of choice using the TimeUnit class.

Like so:

public static int getOffsetHours(TimeZone timeZone) {
    return (int) TimeUnit.MILLISECONDS.toHours(timeZone.getOffset(System.currentTimeMillis()));
}

Or if you prefer the new Java 8 time API

public static ZoneOffset getOffset(TimeZone timeZone) { //for using ZoneOffsett class
    ZoneId zi = timeZone.toZoneId();
    ZoneRules zr = zi.getRules();
    return zr.getOffset(LocalDateTime.now());
}

public static int getOffsetHours(TimeZone timeZone) { //just hour offset
    ZoneOffset zo = getOffset(timeZone);
    TimeUnit.SECONDS.toHours(zo.getTotalSeconds());
}

An alternative that worked for me is to tell Maven to use http: instead of https: when using Maven Central by adding the following to settings.xml:

<settings>
   .
   .
   .
  <mirrors>
    <mirror>
        <id>central-no-ssl</id>
        <name>Central without ssl</name>
        <url>http://repo.maven.apache.org/maven2</url>
        <mirrorOf>central</mirrorOf>
    </mirror>
  </mirrors>
   .
   .
   .
</settings>

Your mileage may vary of course.

Ex Microsoft Developer's Opinion

I worked on a core team for the MSDN website. Now, I use c# razor for ecommerce sites with my programming team and we focus heavy on jQuery front end with back end c# razor pages and LINQ-Entity memory database so the pages are 1-2 millisecond response times even on nested for loops with queries and no page caching. We don't use MVC, just plain ASP.NET with razor pages being mapped with URL Rewrite module for IIS 7, no ASPX pages or ViewState or server-side event programming at all. It doesn't have the extra (unnecessary) layers MVC puts in code constructs for the regex challenged. Less is more for us. Its all lean and mean but I give props to MVC for its testability but that's all.

Razor pages have no event life cycle like ASPX pages. Its just rendering as one requested page. C# is such a great language and Razor gets out of its way nicely to let it do its job. The anonymous typing with generics and linq make life so easy with c# and razor pages. Using Razor pages will help you think and code lighter.

One of the drawback of Razor and MVC is there is no ViewState-like persistence. I needed to implement a solution for that so I ended up writing a jQuery plugin for that here -> http://www.jasonsebring.com/dumbFormState which is an HTML 5 offline storage supported plugin for form state that is working in all major browsers now. It is just for form state currently but you can use window.sessionStorage or window.localStorage very simply to store any kind of state across postbacks or even page requests, I just bothered to make it autosave and namespace it based on URL and form index so you don't have to think about it.

For those with a git gui bent, you can also use gitk.

Right click on the commit you want to return to and select "Reset master branch to here". Then choose hard from the next menu.

Well, you could erase() the first character too (note that erase() modifies the string):

m_VirtualHostName.erase(0, 1);
m_VirtualHostName.erase(m_VirtualHostName.size() - 1);

But in this case, a simpler way is to take a substring:

m_VirtualHostName = m_VirtualHostName.substr(1, m_VirtualHostName.size() - 2);

Be careful to validate that the string actually has at least two characters in it first...

If you need the construct for a quick example to play with, use the : operator.

But if you are creating a vector/range of numbers dynamically, then use seq() instead.

Let's say you are creating the vector/range of numbers from a to b with a:b, and you expect it to be an increasing series. Then, if b is evaluated to be less than a, you will get a decreasing sequence but you will never be notified about it, and your program will continue to execute with the wrong kind of input.

In this case, if you use seq(), you can set the sign of the by argument to match the direction of your sequence, and an error will be raised if they do not match. For example,

seq(a, b, -1)

will raise an error for a=2, b=6, because the coder expected a decreasing sequence.

127.0.0.1 restricts access on every interface on port 8000 except development computer. change it to 0.0.0.0:8000 this will allow connection from curl.

You will simply need to do a type check for each of the basic numeric types.

Here's an extension method that should do the job:

public static bool IsNumber(this object value)
{
    return value is sbyte
            || value is byte
            || value is short
            || value is ushort
            || value is int
            || value is uint
            || value is long
            || value is ulong
            || value is float
            || value is double
            || value is decimal;
}

This should cover all numeric types.

Update

It seems you do actually want to parse the number from a string during deserialisation. In this case, it would probably just be best to use double.TryParse.

string value = "123.3";
double num;
if (!double.TryParse(value, out num))
    throw new InvalidOperationException("Value is not a number.");

Of course, this wouldn't handle very large integers/long decimals, but if that is the case you just need to add additional calls to long.TryParse / decimal.TryParse / whatever else.

This is my json data:

[
   {
      "name":"Test",
      "value":"TestValue"
   },
   {
      "name":"Test",
      "value":"TestValue"
   }
]

Powershell script:

$data = Get-Content "Path to json file" | Out-String | ConvertFrom-Json

foreach ($line in $data) {
     $line.name
}

Signed integers in C represent numbers. If a and b are variables of signed integer types, the standard will never require that a compiler make the expression a+=b store into a anything other than the arithmetic sum of their respective values. To be sure, if the arithmetic sum would not fit into a, the processor might not be able to put it there, but the standard would not require the compiler to truncate or wrap the value, or do anything else for that matter if values that exceed the limits for their types. Note that while the standard does not require it, C implementations are allowed to trap arithmetic overflows with signed values.

Unsigned integers in C behave as abstract algebraic rings of integers which are congruent modulo some power of two, except in scenarios involving conversions to, or operations with, larger types. Converting an integer of any size to a 32-bit unsigned type will yield the member corresponding to things which are congruent to that integer mod 4,294,967,296. The reason subtracting 3 from 2 yields 4,294,967,295 is that adding something congruent to 3 to something congruent to 4,294,967,295 will yield something congruent to 2.

Abstract algebraic rings types are often handy things to have; unfortunately, C uses signedness as the deciding factor for whether a type should behave as a ring. Worse, unsigned values are treated as numbers rather than ring members when converted to larger types, and unsigned values smaller than int get converted to numbers when any arithmetic is performed upon them. If v is a uint32_t which equals 4,294,967,294, then v*=v; should make v=4. Unfortunately, if int is 64 bits, then there's no telling what v*=v; could do.

Given the standard as it is, I would suggest using unsigned types in situations where one wants the behavior associated with algebraic rings, and signed types when one wants to represent numbers. It's unfortunate that C drew the distinctions the way it did, but they are what they are.

Sadly, as of this writing, DESPITE their own documentation readme, there is no src.zip in the JDK 7 or 8 install directories when you download the Windows version.

Note: perhaps this happens because many of us don't actually run the install .exe, but instead extract it. Many of us don't run the Java install (the full blown windows install) for security reasons....we just want the JDK put someplace out of the way where potential viruses cannot find it.

But their policy regarding the windows .exe (whatever it truly is) is indeed nuts, HOWEVER, the src.zip DOES exist in the linux install (a .tar.gz). There are multiple ways of extracting a .tar and a .gz, and I prefer the free "7Zip" utility.

1. download the Linux 64 bit .tar.gz
2. use 7zip to uncompress the .tar.gz to a .tar
3. use 7zip to extract the .tar to the installation directory
4. src.zip will be waiting for you in that installation directory.
5. pull it out and place it where you like.

Oracle, this is really beyond stupid.

System.getProperty("java.class.path")

For proxy_upstream timeout, I tried the above setting but these didn't work.

Setting resolver_timeout worked for me, knowing it was taking 30s to produce the upstream timeout message. E.g. me.atwibble.com could not be resolved (110: Operation timed out).

You can use SimpleDateFormat

For example something like:

boolean isLegalDate(String s) {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    sdf.setLenient(false);
    return sdf.parse(s, new ParsePosition(0)) != null;
}

solve this issue for angular

I've created my own genstrings sort of tool for extracting strings using a custom translation function

extension String {

    func localizedWith(comment:String) -> String {
        return NSLocalizedString(self, tableName: nil, bundle: Bundle.main, value: "", comment: comment)
    }

}

It will parse all your swift files and exports the strings and comments in your code to a .strings file.

Probably not the easiest way to do it, but it is possible.

I am aware this is an old question but my solution may assist others.

I find that the JSON(P) services which make this easy do not last forever but the following JavaScript works well for me at the time of writing.

<script type="text/javascript">function z (x){ document.getElementById('y').innerHTML=x.query }</script>
<script type='text/javascript' src='http://ip-api.com/json/zero.eu.org?callback=z'></script>

The above writes my server's IP on the page it is located but the script can be modified to find any IP by changing 'zero.eu.org' to another domain name. This can be seen in action on my page at: http://meon.zero.eu.org/

You need seek to the beginning of the file before writing and then use file.truncate() if you want to do inplace replace:

import re

myfile = "path/test.xml"

with open(myfile, "r+") as f:
    data = f.read()
    f.seek(0)
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))
    f.truncate()

The other way is to read the file then open it again with open(myfile, 'w'):

with open(myfile, "r") as f:
    data = f.read()

with open(myfile, "w") as f:
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))

Neither truncate nor open(..., 'w') will change the inode number of the file (I tested twice, once with Ubuntu 12.04 NFS and once with ext4).

By the way, this is not really related to Python. The interpreter calls the corresponding low level API. The method truncate() works the same in the C programming language: See http://man7.org/linux/man-pages/man2/truncate.2.html

The error in question may also be caused by disabled JarScanner in tomcat/conf/context.xml.

See also Upgrade from Tomcat 8.0.39 to 8.0.41 results in 'failed to scan' errors.

<JarScanner scanManifest="false"/> allows to avoid both problems.

You could use a HTML DTD, and the generic XML parsing libraries.

I solved this problem with setting architectures and valid architectures same for all pods as for my project. So the hole solution in my case was:

• update cocoa pods: sudo gem update cocoa pods
• update pods: pod update
• In your Pods go to to your Build settings > Architectures and set here Architectures and Valid Architectures to exact same values as in main project.

Check out angular-ui, specifically, route checking: http://angular-ui.github.io/ui-utils/

The inner finally is executed prior to throwing the exception to the outer block.

public class TryCatchFinally {

  public static void main(String[] args) throws Exception {

    try{
        System.out.println('A');
        try{
            System.out.println('B');
            throw new Exception("threw exception in B");
        }
        finally
        {
            System.out.println('X');
        }
        //any code here in the first try block 
        //is unreachable if an exception occurs in the second try block
    }
    catch(Exception e)
    {
        System.out.println('Y');
    }
    finally
    {
        System.out.println('Z');
    }
  }
}

Results in

A
B
X
Y
Z

I was missing this authenticator object argument in the below line

Session session = Session.getInstance(props, new GMailAuthenticator(username, password));

This line solved my problem now I can send mail through my Java application. Rest of the code is simple just like above.

You can also use listView.setOnItemLongClickListener to delete selected item. Below is the code.

// listView = name of your ListView

  listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int 
        position, long id) {

        // it will get the position of selected item from the ListView

final int selected_item = position;

            new AlertDialog.Builder(MainActivity.this).
                    setIcon(android.R.drawable.ic_delete)
                    .setTitle("Are you sure...")
                    .setMessage("Do you want to delete the selected item..?")
                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which)
                        {
                            list.remove(selected_item);
                            arrayAdapter.notifyDataSetChanged();
                        }
                    })
                    .setNegativeButton("No" , null).show();

            return true;
        }
    });

The real reason because set does not work is the fact, that it uses the hash function to distinguish different values. This means that sets only allows hashable objects. Why a list is not hashable is already pointed out.

to change text color of Navigation Drawer

we use app:itemTextColor="@color/white"

to change incon color of navigation Drawer

use app:itemIconTint="@color/black"

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/naView"
        app:itemIconTint="@color/black"
        android:layout_width="match_parent"
        app:menu="@menu/navmenu"
        app:itemTextColor="@color/white"
        app:headerLayout="@layout/nav_header"
        android:layout_height="match_parent"
        app:itemTextAppearance="?android:textAppearanceMedium"
        android:fitsSystemWindows="true"
        android:layout_gravity="start"
        />

One solution would be to divide your table into 20 columns of 5% width each, then use colspan on each real column to get the desired width, like this:

<html>_x000D_
<body bgcolor="#14B3D9">_x000D_
<table width="100%" border="1" bgcolor="#ffffff">_x000D_
    <colgroup>_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
        <col width="5%"><col width="5%">_x000D_
    </colgroup>_x000D_
    <tr>_x000D_
        <td colspan=5>25</td>_x000D_
        <td colspan=10>50</td>_x000D_
        <td colspan=5>25</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td colspan=10>50</td>_x000D_
        <td colspan=6>30</td>_x000D_
        <td colspan=4>20</td>_x000D_
    </tr>_x000D_
</table>_x000D_
</body>_x000D_
</html>

JSFIDDLE

Regex should be a fast approach:

re.search('[a-zA-Z]', the_string)

I have similar thing. For example, to shift by two...

def Shift(*args):
    return args[len(args)-2:]+args[:len(args)-2]

Exactly what Nick Carver did there but I think it would be best if used the DOM setAttribute method.

<script type="text/javascript">
   document.getElementById("myLink").onclick = function() {
   var link = document.getElementById("abc");
   link.setAttribute("href", "xyz.php");
   return false;
   }
</script>

It's one extra line of code but find it better structure-wise.

Something like this - for each line read into string variable a:

>>> a = "123,456"
>>> b = a.split(",")
>>> b
['123', '456']
>>> c = [int(e) for e in b]
>>> c
[123, 456]
>>> x, y = c
>>> x
123
>>> y
456

Now you can do what is necessary with x and y as assigned, which are integers.

For Angular 1 or 2 (but not for Angular 4+):

You can also open the console and go to the element tab on the developer tools of whatever browser you use.

Or

Type angular.version to access the Javascript object that holds angular version.

For Angular 4+ There is are the number of ways as listed below :

Write below code in the command prompt/or in the terminal in the VS Code.

1. ng version or ng --version (See the attachment for the reference.)
2. ng v
3. ng -v

In the terminal you can find the angular version as shown in the attached image :

4. You can also open the console and go to the element tab on the developer tools of whatever browser you use. As displayed in the below image :

5.Find the package.json file, You will find all the installed packages and their version.

6. declare the variable named as 'VERSION', Import the dependencies.

import { VERSION } from '@angular/core';

// To display the version in the console.

console.log(VERSION.full); 

On ubuntu 14.04 I needed to create a link in /usr/bin because /usr/bin/env was looking for /usr/bin/node.

ln -s /usr/bin/nodejs /usr/bin/node

The error messages can be found in the builderror.log in each directory so for the message:

look at this file for more information about the exact problem:

I need to add a header to categorize the list item in Drawer

Customize the listView or use expandableListView

I need a radio button to select some of my options

You can do that without modifying the current implementation of NavigationDrawer, You just need to create a custom adapter for your listView. You can add a parent layout as Drawer then you can do any complex layouts within that as normal.

1. Go to Strings.xml file under values.
2. Change the app_name tag to your app_name to want and it is all set, you will be able to see the name you change now.

UICollectionView current visible cell index: Swift 3, 4 and 5+

var visibleCurrentCellIndexPath: IndexPath? {
    for cell in self.collectionView.visibleCells {
        let indexPath = self.collectionView.indexPath(for: cell)
        return indexPath
     }
        
     return nil
}

As an Extension:

extension UICollectionView {
  var visibleCurrentCellIndexPath: IndexPath? {
    for cell in self.visibleCells {
      let indexPath = self.indexPath(for: cell)
      return indexPath
    }
    
    return nil
  }
}

Usage:

if let indexPath = collectionView.visibleCurrentCellIndexPath { 
   /// do something
}

Late to the party. I'm on Windows 10 with JDK 1.8 and Eclipse MARS 1.
I find that

getClass().getClassLoader().getResourceAsStream("path/to/resource");

works and

getClass().getClassLoader().getResourceAsStream("path"+File.separator+"to"+File.separator+"resource");

does not work and

getClass().getClassLoader().getResourceAsStream("path\to\resource");

does not work. The last two are equivalent. So... I have good reason to NOT use File.separator.

This function returns the actual used range to the lower right limit. It returns "Nothing" if the sheet is empty.

Here is the most simple way.

import tkinter as tk

root = tk.Tk()

root.geometry('200x200')
root.resizable(width=0, height=0)

root.mainloop()

I don't think there is anything to specify. It's pretty straight forward.

Similar to Yipio, I added notab="notab" as an attribute to any element I wanted to disable the tab too. My jQuery is then one line.

$('input[notab=notab]').on('keydown', function(e){ if (e.keyCode == 9)  e.preventDefault() });

Btw, keypress doesn't work for many control keys.

If you want to combine a Map for efficient retrieval with a SortedMap, you may use the ConcurrentSkipListMap.

Of course, you need the key to be the value used for sorting.

If you can ping the FQDN, look at how DNS devolution is set up the PC.

Winsock API which MS ping will automatically use the FQDN of the client PC if append primary and connection specific DNS suffix is checked in TCP/IP advanced DNS settings. If the host is in another domain, the client must perform DNS devolution.

Under XP TCP/IP advanced properties DNS, make sure append parent suffixes is checked so that the ping request traverses the domain back to the parent.

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

I had this error aswell.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.

I also use OleDbDataReader.IsDBNull()

if ( myReader.IsDBNull(colNum) ) { retrievedValue = ""; }
else { retrievedValue = myReader.GetString(colNum); }

The server first tries to authenticate you by public key. That doesn't work (I guess you haven't set one up), so it then falls back to 'keyboard-interactive'. It should then ask you for a password, which presumably you're not getting right. Did you see a password prompt?

Try:

echo quit | telnet IP 22 2>/dev/null | grep Connected

A great way using C# and Linq here:

public static bool HasSpecialCharacter(this string s)
{
    foreach (var c in s)
    {
        if(!char.IsLetterOrDigit(c))
        {
            return true;
        }
    }
    return false;
 }

And access it like this:

myString.HasSpecialCharacter();

Use document.scrollTop to change the position of the document. Set the scrollTop of the document equal to the bottom of the featured section of your site

Try gzipping some data through the gzip libary like this...

import gzip
content = "Lots of content here"
f = gzip.open('Onlyfinnaly.log.gz', 'wb')
f.write(content)
f.close()

... then run your code as posted ...

import gzip
f=gzip.open('Onlyfinnaly.log.gz','rb')
file_content=f.read()
print file_content

This method worked for me as for some reason the gzip library fails to read some files.

You can do like this :

List<String> temp = new ArrayList<String>(Arrays.asList("1", "12"));

I don't think you can use fractional seconds with to_date or the DATE type in Oracle. I think you need to_timestamp which returns a TIMESTAMP type.

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

You need to move the global declaration inside your function:

class TestClass():
    def run(self):
        global g_c
        for i in range(10):
            g_c = 1
            print(g_c)

The statement tells the Python compiler that any assignments (and other binding actions) to that name are to alter the value in the global namespace; the default is to put any name that is being assigned to anywhere in a function, in the local namespace. The statement only applies to the current scope.

Since you are never assigning to g_c in the class body, putting the statement there has no effect. The global statement only ever applies to the scope it is used in, never to any nested scopes. See the global statement documentation, which opens with:

The global statement is a declaration which holds for the entire current code block.

Nested functions and classes are not part of the current code block.

I'll insert the obligatory warning against using globals to share changing state here: don't do it, this makes it harder to reason about the state of your code, harder to test, harder to refactor, etc. If you must share a changing singleton state (one value in the whole program) then at least use a class attribute:

class TestClass():
    g_c = 0

    def run(self):
        for i in range(10):
            TestClass.g_c = 1
            print(TestClass.g_c)  # or print(self.g_c)

t = TestClass()
t.run()

print(TestClass.g_c)

Note how we can still access the same value from the outside, namespaced to the TestClass namespace.

enum ServicePlatform {
    UPLAY = "uplay",
    PSN = "psn",
    XBL = "xbl"
}

becomes:

{ UPLAY: 'uplay', PSN: 'psn', XBL: 'xbl' }

so

ServicePlatform.UPLAY in ServicePlatform // false

SOLUTION:

ServicePlatform.UPLAY.toUpperCase() in ServicePlatform // true

I am also new to R but trying to understand how ggplot works I think I get another way to do it. I just share probably not as a complete perfect solution but to add some different points of view.

I know ggplot is made to work with dataframes better but maybe it can be also sometimes useful to know that you can directly plot two vectors without using a dataframe.

Loading data. Original date vector length is 100 while var0 and var1 have length 50 so I only plot the available data (first 50 dates).

var0 <- 100 + c(0, cumsum(runif(49, -20, 20)))
var1 <- 150 + c(0, cumsum(runif(49, -10, 10)))
date <- seq(as.Date("2002-01-01"), by="1 month", length.out=50)    

Plotting

ggplot() + geom_line(aes(x=date,y=var0),color='red') + 
           geom_line(aes(x=date,y=var1),color='blue') + 
           ylab('Values')+xlab('date')

However I was not able to add a correct legend using this format. Does anyone know how?

Even without pop the list we can do with set_index

pd.DataFrame(table).T.set_index(0).T
Out[11]: 
0 Heading1 Heading2
1        1        2
2        3        4

Update from_records

table = [['Heading1', 'Heading2'], [1 , 2], [3, 4]]

pd.DataFrame.from_records(table[1:],columns=table[0])
Out[58]: 
   Heading1  Heading2
0         1         2
1         3         4

There are some challenges when it comes to keypress event. Jan Wolter's article on key events is a bit old but explains well why key event detection can be hard.

A few things to note:

1. keyCode, which, charCode have different value/meaning in keypress from keyup and keydown. They are all deprecated, however supported in major browsers.
2. Operating system, physical keyboards, browsers(versions) could all have impact on key code/values.
3. key and code are the recent standard. However, they are not well supported by browsers at the time of writing.

To tackle keyboard events in react apps, I implemented react-keyboard-event-handler. Please have a look.

If you have the stats toolbox, then you can compute

Z = zscore(S);

In case you also need support for Internet Explorer 6, just overflow the html

$("html").css("overflow", "hidden");

and

$("html").css("overflow", "auto");

I am late in answer, but posting with hope that it will help others.

In terms of Speed, Parcelable > Serializable. But, Custom Serializable is exception. It is almost in range of Parcelable or even more faster.

Reference : https://www.geeksforgeeks.org/customized-serialization-and-deserialization-in-java/

Example :

Custom Class to be serialized

class MySerialized implements Serializable { 

    String deviceAddress = "MyAndroid-04"; 

    transient String token = "AABCDS"; // sensitive information which I do not want to serialize

    private void writeObject(ObjectOutputStream oos) throws Exception {
        oos.defaultWriteObject();
        oos.writeObject("111111" + token); // Encrypted token to be serialized
    }

    private void readObject(ObjectInputStream ois) throws Exception {
        ois.defaultReadObject(); 
        token = ((String) ois.readObject()).subString(6);  // Decrypting token
    }

}

You need to import the map operator:

import 'rxjs/add/operator/map'

GitHub has a new option relative to the preceding answers, just copy/paste the command lines from the PR:

1. Scroll to the bottom of the PR to see the Merge or Squash and merge button
2. Click the link on the right: view command line instructions
3. Press the Copy icon to the right of Step 1
4. Paste the commands in your terminal

If you are using jQuery 1.2 or newer, you can simply use these:

$(window).width();
$(document).width();
$(window).height();
$(document).height();

From there it is a simple matter to decide the height of your element.

public List<int> GetPositions(string source, string searchString)
{
    List<int> ret = new List<int>();
    int len = searchString.Length;
    int start = -len;
    while (true)
    {
        start = source.IndexOf(searchString, start + len);
        if (start == -1)
        {
            break;
        }
        else
        {
            ret.Add(start);
        }
    }
    return ret;
}

Call it like this:

List<int> list = GetPositions("bob is a chowder head bob bob sldfjl", "bob");
// list will contain 0, 22, 26

You don't need use so many prefixes for full use, because if you choose prefix for old firefox, you don't need use prefix for new firefox.

So for full use, enough use this code:

img.grayscale {
    filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale"); /* Firefox 10+, Firefox on Android */
    filter: gray; /* IE6-9 */
    -webkit-filter: grayscale(100%); /* Chrome 19+, Safari 6+, Safari 6+ iOS */
}

img.grayscale.disabled {
    filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'1 0 0 0 0, 0 1 0 0 0, 0 0 1 0 0, 0 0 0 1 0\'/></filter></svg>#grayscale");
    filter: none;
    -webkit-filter: grayscale(0%);
}

I agree with Swingley's answer, and I think it is an important point a lot of these more elaborate solutions are missing. If you are only concerned with the keys in the associative array and all the values are '1', then simply store the 'keys' as values in an array.

Instead of:

var a = { b:1, z:1, a:1 };
// relatively elaborate code to retrieve the keys and sort them

Use:

var a = [ 'b', 'z', 'a' ];
alert(a.sort());

The one drawback to this is that you can not determine whether a specific key is set as easily. See this answer to javascript function inArray for an answer to that problem. One issue with the solution presented is that a.hasValue('key') is going to be slightly slower than a['key']. That may or may not matter in your code.

Difference: When I first installed node, it installed as 'nodejs'. When I upgraded it, it created 'node'. By executing node, we are actually executing nodejs. Node is just a reference to nodejs. From my experience, when I upgraded, it affected both the versions (as it is supposed to). When I do nodejs -v or node -v, I get the new version.

Upgrading: npm update is used to update the packages in the current directory. Check https://docs.npmjs.com/cli/update

To upgrade node version, based on the OS you are using, follow the commands here https://nodejs.org/en/download/package-manager/

Follow these basic steps to fix this problem,

Step 1: Go to Dashboard,

Step 2: Go to "App Review" tab,

Step 3: Enable the "Make test public?" option, Like Below image,

Put it in a JScrollPane

I'm sticking to the question as the title states and not the discussion. Which view is top visible on any given point?

@implementation UIView (Extra)

- (UIView *)findTopMostViewForPoint:(CGPoint)point
{
    for(int i = self.subviews.count - 1; i >= 0; i--)
    {
        UIView *subview = [self.subviews objectAtIndex:i];
        if(!subview.hidden && CGRectContainsPoint(subview.frame, point))
        {
            CGPoint pointConverted = [self convertPoint:point toView:subview];
            return [subview findTopMostViewForPoint:pointConverted];
        }
    }

    return self;
}

- (UIWindow *)topmostWindow
{
    UIWindow *topWindow = [[[UIApplication sharedApplication].windows sortedArrayUsingComparator:^NSComparisonResult(UIWindow *win1, UIWindow *win2) {
        return win1.windowLevel - win2.windowLevel;
    }] lastObject];
    return topWindow;
}

@end

Can be used directly with any UIWindow as receiver or any UIView as receiver.

Here is a quick-and-dirty way to replace all the broken images, and there is no need to change the HTML code ;)

codepen example

    $("img").each(function(){
        var img = $(this);
        var image = new Image();
        image.src = $(img).attr("src");
        var no_image = "https://dummyimage.com/100x100/7080b5/000000&text=No+image";
        if (image.naturalWidth == 0 || image.readyState == 'uninitialized'){
            $(img).unbind("error").attr("src", no_image).css({
                height: $(img).css("height"),
                width: $(img).css("width"),
            });
        }
  });

Things are about to change on the "eol conversion" front, with the upcoming Git 1.7.2:

A new config setting core.eol is being added/evolved:

This is a replacement for the 'Add "core.eol" config variable' commit that's currently in pu (the last one in my series).
Instead of implying that "core.autocrlf=true" is a replacement for "* text=auto", it makes explicit the fact that autocrlf is only for users who want to work with CRLFs in their working directory on a repository that doesn't have text file normalization.
When it is enabled, "core.eol" is ignored.

Introduce a new configuration variable, "core.eol", that allows the user to set which line endings to use for end-of-line-normalized files in the working directory.
It defaults to "native", which means CRLF on Windows and LF everywhere else. Note that "core.autocrlf" overrides core.eol.
This means that:

[core]
  autocrlf = true

puts CRLFs in the working directory even if core.eol is set to "lf".

core.eol:

Sets the line ending type to use in the working directory for files that have the text property set.
Alternatives are 'lf', 'crlf' and 'native', which uses the platform's native line ending.
The default value is native.

Other evolutions are being considered:

For 1.8, I would consider making core.autocrlf just turn on normalization and leave the working directory line ending decision to core.eol, but that will break people's setups.

git 2.8 (March 2016) improves the way core.autocrlf influences the eol:

See commit 817a0c7 (23 Feb 2016), commit 6e336a5, commit df747b8, commit df747b8 (10 Feb 2016), commit df747b8, commit df747b8 (10 Feb 2016), and commit 4b4024f, commit bb211b4, commit 92cce13, commit 320d39c, commit 4b4024f, commit bb211b4, commit 92cce13, commit 320d39c (05 Feb 2016) by Torsten Bögershausen (tboegi).
^{(Merged by Junio C Hamano -- gitster -- in commit c6b94eb, 26 Feb 2016)}

convert.c: refactor crlf_action

Refactor the determination and usage of crlf_action.
Today, when no "crlf" attribute are set on a file, crlf_action is set to CRLF_GUESS. Use CRLF_UNDEFINED instead, and search for "text" or "eol" as before.

Replace the old CRLF_GUESS usage:

CRLF_GUESS && core.autocrlf=true -> CRLF_AUTO_CRLF
CRLF_GUESS && core.autocrlf=false -> CRLF_BINARY
CRLF_GUESS && core.autocrlf=input -> CRLF_AUTO_INPUT

Make more clear, what is what, by defining:

- CRLF_UNDEFINED : No attributes set. Temparally used, until core.autocrlf
                   and core.eol is evaluated and one of CRLF_BINARY,
                   CRLF_AUTO_INPUT or CRLF_AUTO_CRLF is selected
- CRLF_BINARY    : No processing of line endings.
- CRLF_TEXT      : attribute "text" is set, line endings are processed.
- CRLF_TEXT_INPUT: attribute "input" or "eol=lf" is set. This implies text.
- CRLF_TEXT_CRLF : attribute "eol=crlf" is set. This implies text.
- CRLF_AUTO      : attribute "auto" is set.
- CRLF_AUTO_INPUT: core.autocrlf=input (no attributes)
- CRLF_AUTO_CRLF : core.autocrlf=true  (no attributes)

As torek adds in the comments:

all these translations (any EOL conversion from eol= or autocrlf settings, and "clean" filters) are run when files move from work-tree to index, i.e., during git add rather than at git commit time.
(Note that git commit -a or --only or --include do add files to the index at that time, though.)

For more on that, see "What is difference between autocrlf and eol".

you npm version is old, try to run the following command:

npm i npm@latest -g

If you are reading from a file and you have an array or dictionary with values of multiple datatypes, the following will be useful. Just check whether the variable can be type casted to int(or any other datatype you want to enforce) or not.

try :
    int(a);
    #Variable a is int
except ValueError : 
    # Variable a is not an int

For Swift 4.2

@IBOutlet weak var tableVw: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Set self as tableView delegate
    tableVw.delegate = self

    tableVw.rowHeight = UITableView.automaticDimension
    tableVw.estimatedRowHeight = UITableView.automaticDimension
}

// UITableViewDelegate Method 
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

    return UITableView.automaticDimension
}

Happy Coding :)

In MemSQL do the following:

-- DROP FUNCTION IF EXISTS InlineMax;
DELIMITER //
CREATE FUNCTION InlineMax(val1 INT, val2 INT) RETURNS INT AS
DECLARE
  val3 INT = 0;
BEGIN
 IF val1 > val2 THEN
   RETURN val1;
 ELSE
   RETURN val2;
 END IF; 
END //
DELIMITER ;

SELECT InlineMax(1,2) as test;

• Place your cursor at the end of the text.
• Press SHIFT and ->. The cursor will move to the next line.
• Press CTRL-F and type , in "Replace with:" and press ENTER.

You will need to put a quote at the beginning of your first text and the end of your last.

This should do:

samp2 <- samp[,-1]
rownames(samp2) <- samp[,1]

So in short, no there is no alternative to reassigning.

Edit: Correcting myself, one can also do it in place: assign rowname attributes, then remove column:

R> df<-data.frame(a=letters[1:10], b=1:10, c=LETTERS[1:10])
R> rownames(df) <- df[,1]
R> df[,1] <- NULL
R> df
   b c
a  1 A
b  2 B
c  3 C
d  4 D
e  5 E
f  6 F
g  7 G
h  8 H
i  9 I
j 10 J
R> 

Use cURL,

Check if you have it via phpinfo();

And for the code:

function getHtml($url, $post = null) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    if(!empty($post)) {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    } 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

Compare date only instead of date + time (NOW) with:

CURDATE()

Well, it would be easier to exclude them in the first place:

authorsList = authorsList.Where(x => x.FirstName != "Bob").ToList();

However, that would just change the value of authorsList instead of removing the authors from the previous collection. Alternatively, you can use RemoveAll:

authorsList.RemoveAll(x => x.FirstName == "Bob");

If you really need to do it based on another collection, I'd use a HashSet, RemoveAll and Contains:

var setToRemove = new HashSet<Author>(authors);
authorsList.RemoveAll(x => setToRemove.Contains(x));

If you want know, the how may nodejs processes running then you can use this command

ps -aef | grep node

So it will give list of nodejs process with it's project name. It will be helpful when you are running multipe nodejs application & you want kill specific process for the specific project.

Above command will give output like

XXX  12886  1741  1 12:36 ?        00:00:05 /home/username/.nvm/versions/node/v9.2.0/bin/node --inspect-brk=43443 /node application running path.

So to kill you can use following command

kill -9 12886

So it will kill the spcefic node process

I had some difficulty following the most popular answer for my circumstances. For example, my validation was failing with characters such as ; or [. I was not interested in white-listing my special characters, so I instead leveraged [^\w\s] as a test - simply put - match non word characters (including numeric) and non white space characters. To summarize, here is what worked for me...

• at least 8 characters
• at least 1 numeric character
• at least 1 lowercase letter
• at least 1 uppercase letter
• at least 1 special character

/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[^\w\s]).{8,}$/

Have you closed the < web-app > tag in your web.xml? From what you have posted, the closing tag seems to be missing.

cursor.rowcount will usually be set to 0.

If, however, you are running a statement that would never return a result set (such as INSERT without RETURNING, or SELECT ... INTO), then you do not need to call .fetchall(); there won't be a result set for such statements. Calling .execute() is enough to run the statement.

Note that database adapters are also allowed to set the rowcount to -1 if the database adapter can't determine the exact affected count. See the PEP 249 Cursor.rowcount specification:

The attribute is -1 in case no .execute*() has been performed on the cursor or the rowcount of the last operation is cannot be determined by the interface.

The sqlite3 library is prone to doing this. In all such cases, if you must know the affected rowcount up front, execute a COUNT() select in the same transaction first.

You can do this natively as follows:

1. Select the table and use Excel to sort it on Last Name
2. Create a 2-row by 1-column advanced filter criteria, say in E1 and E2, where E1 is empty and E2 contains the formula =C6="" where C6 is the first data cell of the phone number column.
3. Select the table and use advanced filter, copy to a range, using the criteria range in E1:E2 and specify where you want to copy the output to

If you want to do this programmatically I suggest you use the Macro Recorder to record the above steps and look at the code.

Here is a functional approach using map, itertools.repeat and operator.mul:

import operator
from itertools import repeat


def scalar_multiplication(vector, scalar):
    yield from map(operator.mul, vector, repeat(scalar))

Example of usage:

>>> v = [1, 2, 3, 4]
>>> c = 3
>>> list(scalar_multiplication(v, c))
[3, 6, 9, 12]

Nothing have to do... when you are creating dbcontext for code first approach initialize namespace below the fluent API area make list of sp and use it another place where you want.

}

this is more likely happening because somewhere along your certificate chain you have a certificate, more likely an old root, which is still signed with the MD2RSA algorythm.

You need to locate it into your certificate store and delete it.

Then get back to your certification authority and ask them for then new root.

It will more likely be the same root with the same validity period but it has been recertified with SHA1RSA.

Hope this help.

}

Also you can add Tidy markup correction to make HTML valid.

If you want to get what is the difference between two hashes, you can do this:

h1 = {:a => 20, :b => 10, :c => 44}
h2 = {:a => 2, :b => 10, :c => "44"}
result = {}
h1.each {|k, v| result[k] = h2[k] if h2[k] != v }
p result #=> {:a => 2, :c => "44"}

If it's not a typed dataset, then you probably want to do something like this, using the Linq-to-DataSet extension methods:

var distinctValues = dsValues.AsEnumerable()
                        .Select(row => new {
                            attribute1_name = row.Field<string>("attribute1_name"),
                            attribute2_name = row.Field<string>("attribute2_name")
                         })
                        .Distinct();

Make sure you have a using System.Data; statement at the beginning of your code in order to enable the Linq-to-Dataset extension methods.

Hope this helps!

Deleted the .suo file in solution folder to solve the problem.

Use

s.replace(/\d/g, "X")

which will replace all occurrences. The g means global match and thus will not stop matching after the first occurrence.

Or to stay with your RegExp constructor:

s.replace(new RegExp("\\d", "g"), "X")

In my case I didn't want to remove eclipse because in corporate world we can't control everything. Also deleting some files from workspace .matadata could not help. So below hack that I found with trial and error worked for me perfectly :

Go to this path: C:\....\eclipse-Luna\configuration\org.eclipse.core.runtime\

now delete .manager completely.

Start eclipse again and woilaa.. it will run normally.

[In my case, I use eclipse luna. I once abruptly closed the PC when eclipse was open. Then eclipse was not able to start on the next system restart. So keep in mind to close eclipse properly. :) ]

For recent versions of Android Studio, if changing just the Kotlin Target VM version didn't work.

File ? Project Structure ? Modules (app): set both "Source Compatibility" and "Target Compatibility" to "1.8 (Java 8)". Press "OK" and sync project with Gradle.

you could try using Pandas to retrieve information and get it as dataframe

import pyodbc as cnn
import pandas as pd

cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=SQLSRV01;DATABASE=DATABASE;UID=USER;PWD=PASSWORD')

# Copy to Clipboard for paste in Excel sheet
def copia (argumento):
    df=pd.DataFrame(argumento)
    df.to_clipboard(index=False,header=True)


tableResult = pd.read_sql("SELECT * FROM YOURTABLE", cnxn) 

# Copy to Clipboard
copia(tableResult)

# Or create a Excel file with the results
df=pd.DataFrame(tableResult)
df.to_excel("FileExample.xlsx",sheet_name='Results')

I hope this helps! Cheers!

Thread safe simply means that it may be used from multiple threads at the same time without causing problems. This can mean that access to any resources are synchronized, or whatever.

public async Task<IHttpActionResult> PutParent(int id, Parent parent)

            }

            if (id != parent.Id)
            {
                return BadRequest();
            }

            db.Entry(parent).State = EntityState.Modified;

            foreach (Child child in parent.Children)
            {
                db.Entry(child).State = child.Id == 0 ? EntityState.Added : EntityState.Modified;
            }

            try
            {
                await db.SaveChangesAsync();
            }
            catch (DbUpdateConcurrencyException)
            {
                if (!ParentExists(id))
                {
                    return NotFound();
                }
                else
                {
                    throw;
                }
            }

            return Ok(db.Parents.Find(id));
        }

This is how I solved this problem. This way, EF knows which to add which to update.

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.

Whitelist the resource with $sceDelegateProvider

This is caused by a new security policy put in place in Angular 1.2. It makes XSS harder by preventing a hacker from dialling out (i.e. making a request to a foreign URL, potentially containing a payload).

To get around it properly you need to whitelist the domains you want to allow, like this:

angular.module('myApp',['ngSanitize']).config(function($sceDelegateProvider) {
  $sceDelegateProvider.resourceUrlWhitelist([
    // Allow same origin resource loads.
    'self',
    // Allow loading from our assets domain.  Notice the difference between * and **.
    'http://srv*.assets.example.com/**'
  ]);

  // The blacklist overrides the whitelist so the open redirect here is blocked.
  $sceDelegateProvider.resourceUrlBlacklist([
    'http://myapp.example.com/clickThru**'
  ]);
});

This example is lifted from the documentation which you can read here:

https://docs.angularjs.org/api/ng/provider/$sceDelegateProvider

Be sure to include ngSanitize in your app to make this work.

Disabling the feature

If you want to turn off this useful feature, and you're sure your data is secure, you can simply allow **, like so:

angular.module('app').config(function($sceDelegateProvider) {
  $sceDelegateProvider.resourceUrlWhitelist(['**']);
});

There's some great information about this here: https://bugzilla.mozilla.org/show_bug.cgi?id=857142

Still experimenting but so far a minimally invasive solution, aimed only at FF is:

body {
-moz-osx-font-smoothing: grayscale;
}

The idea of a linear index for arrays in matlab is an important one. An array in MATLAB is really just a vector of elements, strung out in memory. MATLAB allows you to use either a row and column index, or a single linear index. For example,

A = magic(3)
A =
     8     1     6
     3     5     7
     4     9     2

A(2,3)
ans =
     7

A(8)
ans =
     7

We can see the order the elements are stored in memory by unrolling the array into a vector.

A(:)
ans =
     8
     3
     4
     1
     5
     9
     6
     7
     2

As you can see, the 8th element is the number 7. In fact, the function find returns its results as a linear index.

find(A>6)
ans =
     1
     6
     8

The result is, we can access each element in turn of a general n-d array using a single loop. For example, if we wanted to square the elements of A (yes, I know there are better ways to do this), one might do this:

B = zeros(size(A));
for i = 1:numel(A)
  B(i) = A(i).^2;
end

B
B =
    64     1    36
     9    25    49
    16    81     4

There are many circumstances where the linear index is more useful. Conversion between the linear index and two (or higher) dimensional subscripts is accomplished with the sub2ind and ind2sub functions.

The linear index applies in general to any array in matlab. So you can use it on structures, cell arrays, etc. The only problem with the linear index is when they get too large. MATLAB uses a 32 bit integer to store these indexes. So if your array has more then a total of 2^32 elements in it, the linear index will fail. It is really only an issue if you use sparse matrices often, when occasionally this will cause a problem. (Though I don't use a 64 bit MATLAB release, I believe that problem has been resolved for those lucky individuals who do.)

I have similar issue, and you know what, it's because of network is disconnected when I test in android device webview and I don't realize it, and the local js no problem to load because it doesn't need network. It seems ridiculous but it waste my ~1 hour to figure out it.

While the accepted answer is correct, I'll add a more elegant version (in my opinion):

boolean idExists = tabPane.getTabs().stream()
    .map(Tab::getId)
    .anyMatch(idToCheck::equals);

Don't neglect using Stream#map() which allows to flatten the data structure before applying the Predicate.

Yes it works fine and is commonly used:

$ echo "hello world" | mail -s "a subject" [email protected]

You can always press CTRL-B + SHIFT-D to choose which client you want to detach from the session.

tmux will list all sessions with their current dimension. Then you simply detach from all the smaller sized sessions.

I stumbled across this article looking for a similar answer. I read @vsync example Using javascript's Number.prototype.toLocaleString: and it appeared to work well. The only complaint I had was that if you had more than a single input type="currency" within your page it would only modify the first instance of it.

As he mentions in his comments it was only designed as an example for stackoverflow.

However, the example worked well for me and although I have little experience with JS I figured out how to modify it so that it will work with multiple input type="currency" on the page using the document.querySelectorAll rather than document.querySelector and adding a for loop.

I hope this can be useful for someone else. ( Credit for the bulk of the code is @vsync )

var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

for ( var i = 0; i < currencyInput.length; i++ ) {

    var currency = 'GBP'
    onBlur( {
        target: currencyInput[ i ]
    } )

    currencyInput[ i ].addEventListener( 'focus', onFocus )
    currencyInput[ i ].addEventListener( 'blur', onBlur )

    function localStringToNumber( s ) {
        return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
    }

    function onFocus( e ) {
        var value = e.target.value;
        e.target.value = value ? localStringToNumber( value ) : ''
    }

    function onBlur( e ) {
        var value = e.target.value

        var options = {
            maximumFractionDigits: 2,
            currency: currency,
            style: "currency",
            currencyDisplay: "symbol"
        }

        e.target.value = ( value || value === 0 ) ?
            localStringToNumber( value ).toLocaleString( undefined, options ) :
            ''
    }
}

    var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

    for ( var i = 0; i < currencyInput.length; i++ ) {

        var currency = 'GBP'
        onBlur( {
            target: currencyInput[ i ]
        } )

        currencyInput[ i ].addEventListener( 'focus', onFocus )
        currencyInput[ i ].addEventListener( 'blur', onBlur )

        function localStringToNumber( s ) {
            return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
        }

As the OP references Number of commits on branch in git I want to add that the given answers there also work with any other branch, at least since git version 2.17.1 (and seemingly more reliably than the answer by Peter van der Does):

working correctly:

git checkout current-development-branch
git rev-list --no-merges --count master..
62
git checkout -b testbranch_2
git rev-list --no-merges --count current-development-branch..
0

The last command gives zero commits as expected since I just created the branch. The command before gives me the real number of commits on my development-branch minus the merge-commit(s)

not working correctly:

git checkout current-development-branch
git rev-list --no-merges --count HEAD
361
git checkout -b testbranch_1
git rev-list --no-merges --count HEAD
361

In both cases I get the number of all commits in the development branch and master from which the branches (indirectly) descend.

Each class file has a version number embedded for the byte code level which the JVM use to see if it likes that particular byte code chunk or not. This is 48 for Java 1.4, 49 for Java 1.5 and 50 for Java 6.

Many compilers exist which can generate byte code at each level, javac uses the "-target" option to indicate which byte code level to generate, and the Java 6 javac can generate byte code for at least 1.4, 1.5 and 6. I do not believe that the compiler inserts anything that can identify the compiler itself which is what I think you ask for. Also the Eclipse compiler is increasingly being used, as it is a single jar which can run with the JRE only.

In a jar file there is usually many classes, and each of them is independent, so you need to investigate all classes in the jar to be certain about the characteristics of the contents.

(The typical method would be to use plot just once to set up the limits, possibly to include the range of all series combined, and then to use points and lines to add the separate series.) To use plot multiple times with par(new=TRUE) you need to make sure that your first plot has a proper ylim to accept the all series (and in another situation, you may need to also use the same strategy for xlim):

# first plot
plot(x, y1, ylim=range(c(y1,y2)))

# second plot  EDIT: needs to have same ylim
par(new = TRUE)
plot(x, y2, ylim=range(c(y1,y2)), axes = FALSE, xlab = "", ylab = "")

This next code will do the task more compactly, by default you get numbers as points but the second one gives you typical R-type-"points":

  matplot(x, cbind(y1,y2))
  matplot(x, cbind(y1,y2), pch=1)

Why don't you place the account number in a div. Style it as you please and then have a hidden input in the form that also contains the account number. Then when the form gets submitted, the value should come through and not be null.

The struct's name is ReducedForm; you need to make an object (instance of the struct or class) and use that. Do this:

ReducedForm MyReducedForm;
MyReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;
MyReducedForm.iSimplifiedDenominator = iDenominator/iGreatCommDivisor;

After doing a lot of things, I upgraded pip, setuptools and virtualenv.

1. python -m pip install -U pip
2. pip install -U setuptools
3. pip install -U virtualenv

I did steps 1, 2 in my virtual environment as well as globally. Next, I installed the package through pip and it worked.

Between int32 and int32_t, (and likewise between int8 and int8_t) the difference is pretty simple: the C standard defines int8_t and int32_t, but does not define anything named int8 or int32 -- the latter (if they exist at all) is probably from some other header or library (most likely predates the addition of int8_t and int32_t in C99).

Plain int is quite a bit different from the others. Where int8_t and int32_t each have a specified size, int can be any size >= 16 bits. At different times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits).

On the other hand, int is guaranteed to be present in every implementation of C, where int8_t and int32_t are not. It's probably open to question whether this matters to you though. If you use C on small embedded systems and/or older compilers, it may be a problem. If you use it primarily with a modern compiler on desktop/server machines, it probably won't be.

Oops -- missed the part about char. You'd use int8_t instead of char if (and only if) you want an integer type guaranteed to be exactly 8 bits in size. If you want to store characters, you probably want to use char instead. Its size can vary (in terms of number of bits) but it's guaranteed to be exactly one byte. One slight oddity though: there's no guarantee about whether a plain char is signed or unsigned (and many compilers can make it either one, depending on a compile-time flag). If you need to ensure its being either signed or unsigned, you need to specify that explicitly.

I know I'm am very late on this, but here some usefull samples:

'select the used cells in column 3 of worksheet wks
wks.columns(3).SpecialCells(xlCellTypeConstants).Select

or

'change all formulas in col 3 to values
with sheet1.columns(3).SpecialCells(xlCellTypeFormulas)
    .value = .value
end with

To find the last used row in column, never rely on LastCell, which is unreliable (it is not reset after deleting data). Instead, I use someting like

 lngLast = cells(rows.count,3).end(xlUp).row

From the help page for ?toupper:

.simpleCap <- function(x) {
    s <- strsplit(x, " ")[[1]]
    paste(toupper(substring(s, 1,1)), substring(s, 2),
          sep="", collapse=" ")
}


> sapply(name, .simpleCap)

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

A visual tour:

Use an array for this.

var markers = [];
for (var i = 0; i < coords.length; ++i) {
    markers[i] = "some stuff";
}

Since Java 8:

List<String> myList = map.keySet().stream().collect(Collectors.toList());

Work with vectors is usually most effective to contact String.

I suggest the following function:

String.prototype.replaceAt=function(index, char) {
    var a = this.split("");
    a[index] = char;
    return a.join("");
}

Run this snippet:

String.prototype.replaceAt=function(index, char) {_x000D_
    var a = this.split("");_x000D_
    a[index] = char;_x000D_
    return a.join("");_x000D_
}_x000D_
_x000D_
var str = "hello world";_x000D_
str = str.replaceAt(3, "#");_x000D_
_x000D_
document.write(str);

I think we can write this fewer styles, without changing the existing color. The following worked for me (in Bootstrap 3.2.0)

.navbar-nav > li > a { padding-top: 5px !important; padding-bottom: 5px !important; }
.navbar { min-height: 32px !important; }
.navbar-brand { padding-top: 5px; padding-bottom: 10px; padding-left: 10px; }

The last one ('navbar-brand') is actually needed only if you have text as your 'brand' name.

They are not identical. Memcache is older but it has some limitations. I was using just fine in my application until I realized you can't store literal FALSE in cache. Value FALSE returned from the cache is the same as FALSE returned when a value is not found in the cache. There is no way to check which is which. Memcached has additional method (among others) Memcached::getResultCode that will tell you whether key was found.

Because of this limitation I switched to storing empty arrays instead of FALSE in cache. I am still using Memcache, but I just wanted to put this info out there for people who are deciding.

I'm using Laravel Lumen to build a small application.
For me it was because I didn't had the DB_USERNAME defined in my .env file.

DB_USERNAME=root

Setting this solved my problem.

System wide C++ change on Ubuntu:

sudo apt-get install clang
sudo update-alternatives --config c++

Will print something like this:

  Selection    Path              Priority   Status
------------------------------------------------------------
* 0            /usr/bin/g++       20        auto mode
  1            /usr/bin/clang++   10        manual mode
  2            /usr/bin/g++       20        manual mode

Then just select clang++.

Necroing this question but there's an explanation that no-one seems to have considered.

STATISTICS - Statistics are not available or misleading

If all of the following are true:

1. The columns feedid and feedDate are likely to be highly correlated (e.g. a feed id is more specific than a feed date and the date parameter is redundant information).
2. There is no index with both columns as sequential columns.
3. There are no manually created statistics covering both these columns.

Then sql server may be incorrectly assuming that the columns are uncorrelated, leading to lower than expected cardinality estimates for applying both restrictions and a poor execution plan being selected. The fix in this case would be to create a statistics object linking the two columns, which is not an expensive operation.

i suggest using phpmyadmin

it’s definitely the best free tool out there and it works on every system with php+mysql

"Visual Studio does not support std::cout as debug tool for non-console applications"
_{- from Marius Amado-Alves' answer to "How can I see cout output in a non-console application?"}

Which means if you use it, Visual Studio shows nothing in the "output" window (in my case VS2008)

To run an executable in mac

1). Move to the path of the file:

cd/PATH_OF_THE_FILE

2). Run the following command to set the file's executable bit using the chmod command:

chmod +x ./NAME_OF_THE_FILE

3). Run the following command to execute the file:

./NAME_OF_THE_FILE

Once you have run these commands, going ahead you just have to run command 3, while in the files path.

Put them in an arrayList in your first class like:

import java.util.ArrayList;
    public class numbers {

    private int number1 = 50;
    private int number2 = 100;

    public ArrayList<int> getNumberList() {
        ArrayList<int> numbersList= new ArrayList<int>();
        numbersList.add(number1);
        numberList.add(number2);
        ....
        return numberList;
    }
}

Then, in your test class you can call numbers.getNumberList() to get your arrayList. In addition, you might want to create methods like addToList / removeFromList in your numbers class so you can handle it the way you need it.

You can also access a variable declared in one class from another simply like

numbers.numberList;

if you have it declared there as public.

But it isn't such a good practice in my opinion, since you probably need to modify this list in your code later. Note that you have to add your class to the import list.

If you can tell me what your app requirements are, i'll be able tell you more precise what i think it's best to do.

I was experiencing this same error, and spent forever adding the suggested startup statements to various config files in my solution, attempting to isolate the framework mismatch. Nothing worked. I also added startup information to my XML schemas. That didn't help either. Looking at the actual file that was causing the problem (which would only say it was "moved or deleted") revealed it was actually the License Compiler (LC).

Deleting the offending licenses.licx file seems to have fixed the problem.

If you dont want to merge the changes and still want to update your local then run:

git reset --hard HEAD  

This will reset your local with HEAD and then pull your remote using git pull.

If you've already committed your merge locally (but haven't pushed to remote yet), and want to revert it as well:

git reset --hard HEAD~1 

if(getResult.Key.Equals(default(T)) && getResult.Value.Equals(default(U)))

You need to use isset() to check whether value is set.

apt-get install python2.7 will work on debian-like linuxes. The python website describes a whole bunch of other ways to get Python.

You can download using this package in node js,

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

If response is in json and not a string then

alert(response.id);
or
alert(response['id']);

otherwise

var response = JSON.parse('{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}');
response.id ; //# => 2231f87c-a62c-4c2c-8f5d-b76d11942301

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

It was KB2553154. Microsoft needs to release a fix. As a developer of Excel applications we can't go to all our clients computers and delete files off them. We are getting blamed for something Microsoft caused.

Two things occur to me.

First, are you sure you mean ManyToOne for address? That means multiple people will have the same address. If it's edited for one of them, it'll be edited for all of them. Is that your intent? 99% of the time addresses are "private" (in the sense that they belong to only one person).

Secondly, do you have any other eager relationships on the Person entity? If I recall correctly, Hibernate can only handle one eager relationship on an entity but that is possibly outdated information.

I say that because your understanding of how this should work is essentially correct from where I'm sitting.

I will explain with simple example

1. [1,3,2] <=> [2,2,2]

   Ruby will start comparing each element of both array from left hand side. 1 for left array is smaller than 2 of right array. Hence left array is smaller than right array. Output will be -1.

2. [2,3,2] <=> [2,2,2]

   As above it will first compare first element which are equal then it will compare second element, in this case second element of left array is greater hence output is 1.

2020 Update: The best practice is to use a library that has already done the hard work for you and doesn't kill your team when you make the switch as pointed out by the originally accepted answer in this video (it's still relevant). Also just to get a sense on trends this is a very helpful chart. After doing my own research on this I chose to use Emotion for my new projects and it has proven to be very flexible and scaleable.

Given that the most upvoted answer from 2015 recommended Radium which is now relegated to maintenance mode. So it seems reasonable to add a list of alternatives. The post discontinuing Radium suggests a few libraries. Each of the sites linked has examples readily available so I will refrain from copy and pasting the code here.

• Emotion which is "inspired by" styled-components among others, uses styles in js and can be framework agnostic, but definitely promotes its React library. Emotion has been kept up to date as of this post.
• styled-components is comparable and offers many of the same features as Emotion. Also actively being maintained. Both Emotion and styled-components have similar syntax. It is built specifically to work with React components.
• JSS Yet another option for styles in js which is framework agnostic though it does have a number of framework packages, React-JSS among them.

If it is a Spring App, just paste the code in config class

        @Bean
        public ObjectMapper getJacksonObjectMapper() {
            ObjectMapper objectMapper = new ObjectMapper();
            objectMapper.findAndRegisterModules();
            objectMapper.configure(
                    com.fasterxml.jackson.databind.SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
            objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
            objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
            return objectMapper;
        }
  

If you need to concatenate paths with quotes, you can use = to replace quotes in a variable. This does not require you to know if the path already contains quotes or not. If there are no quotes, nothing is changed.

@echo off
rem Paths to combine
set DIRECTORY="C:\Directory with spaces"
set FILENAME="sub directory\filename.txt"

rem Combine two paths
set COMBINED="%DIRECTORY:"=%\%FILENAME:"=%"
echo %COMBINED%

rem This is just to illustrate how the = operator works
set DIR_WITHOUT_SPACES=%DIRECTORY:"=%
echo %DIR_WITHOUT_SPACES%

If what you need is UPDATE from SELECT statement you can do something like this:

UPDATE suppliers    
SET city = (SELECT customers.city FROM customers

WHERE customers.customer_name = suppliers.supplier_name)

You could consider using CSS clip: rect(top, right, bottom, left); to clip a fixed positioned element to a parent. See demo at http://jsfiddle.net/lmeurs/jf3t0fmf/.

Beware, use with care!

Though the clip style is widely supported, main disadvantages are that:

1. The parent's position cannot be static or relative (one can use an absolutely positioned parent inside a relatively positioned container);
2. The rect coordinates do not support percentages, though the auto value equals 100%, ie. clip: rect(auto, auto, auto, auto);;
3. Possibillities with child elements are limited in at least IE11 & Chrome34, ie. we cannot set the position of child elements to relative or absolute or use CSS3 transform like scale.

See http://tympanus.net/codrops/2013/01/16/understanding-the-css-clip-property/ for more info.

EDIT: Chrome seems to handle positioning of and CSS3 transforms on child elements a lot better when applying backface-visibility, so just to be sure we added:

-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
backface-visibility: hidden;

to the main child element.

Also note that it's not fully supported by older / mobile browsers or it might take some extra effort. See our implementation for the menu at bellafuchsia.com.

1. IE8 shows the menu well, but menu links are not clickable;
2. IE9 does not show the menu under the fold;
3. iOS Safari <5 does not show the menu well;
4. iOS Safari 5+ repaints the clipped content on scroll after scrolling;
5. FF (at least 13+), IE10+, Chrome and Chrome for Android seem to play nice.

EDIT 2014-11-02: Demo URL has been updated.

I use to work on UNIX-like machines, but recently I have had to do some work with Java on a Windows 7 machine. I have had that problem and this is the I've solved it. It has worked right for me so I hope it can be used for whoever who may have this problem in the future.

These steps are exposed considering a default Java installation on drive C. You should change what it is necessary in case your installation is not a default one.

Change Java default VM on Windows 7

Suppose we have installed Java 8 but for whatever reason we want to keep with Java 7.

1- Start a cmd as administrator

2- Go to C:\ProgramData\Oracle\Java

3- Rename the current directory javapath to javapath_<version_it_refers_to>. E.g.: rename javapath javapath_1.8

4- Create a javapath_<version_you_want_by_default> directory. E.g.: mkdir javapath_1.7

5- cd into it and create the following links:

cd javapath_1.7
mklink java.exe "C:\Program Files\Java\jre7\bin\java.exe"
mklink javaw.exe "C:\Program Files\Java\jre7\bin\javaw.exe"
mklink javaws.exe "C:\Program Files\Java\jre7\bin\javaws.exe"

6- cd out and create a directory link javapath pointing to the desired javapath. E.g.: mklink /D javapath javapath_1.7

7- Open the register and change the key HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion to have the value 1.7

At this point if you execute java -version you should see that you are using java version 1.7:

java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)

8- Finally it is a good idea to create the environment variable JAVA_HOME. To do that I create a directory link named CurrentVersion in C:\Program Files\Java pointing to the Java version I'm interested in. E.g.:

cd C:\Program Files\Java\
mklink /D CurrentVersion .\jdk1.7.0_71

9- And once this is done:

• Right click My Computer and select Properties.
• On the Advanced tab, select Environment Variables, and then edit/create JAVA_HOME to point to where the JDK software is located, in that case, C:\Program Files\Java\CurrentVersion

My 5 cents:

1. Use async/await if and only if you do an IO operation, like DB or external service webservice.
2. Always prefer async calls to DB.
3. Each time you query the DB.

P.S. There are exceptional cases for point 1, but you need to have a good understanding of async internals for this.

As an additional advantage, you can do few IO calls in parallel if needed:

Task task1 = FooAsync(); // launch it, but don't wait for result
Task task2 = BarAsync(); // launch bar; now both foo and bar are running
await Task.WhenAll(task1, task2); // this is better in regard to exception handling
// use task1.Result, task2.Result

NameValueCollection n = Request.QueryString;

if (n.HasKeys())
   {
       //something
   }

Return Value Type: System.Boolean true if the NameValueCollection contains keys that are not null; otherwise, false. LINK

Most of the answers here are either 'UnSafe" or not LittleEndian safe. BitConverter is not LittleEndian safe. So building on an example in here (see the post by PZahra) I made a LittleEndian safe version simply by reading the byte array in reverse when BitConverter.IsLittleEndian == true

void Main(){    
    Console.WriteLine(BitConverter.IsLittleEndian); 
    byte[] bytes = BitConverter.GetBytes(0xdcbaabcdfffe1608);
    //Console.WriteLine(bytes); 
    string hexStr = ByteArrayToHex(bytes);
    Console.WriteLine(hexStr);
}

public static string ByteArrayToHex(byte[] data) 
{ 
   char[] c = new char[data.Length * 2]; 
   byte b; 
  if(BitConverter.IsLittleEndian)
  {
        //read the byte array in reverse
        for (int y = data.Length -1, x = 0; y >= 0; --y, ++x) 
        { 
            b = ((byte)(data[y] >> 4)); 
            c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
            b = ((byte)(data[y] & 0xF)); 
            c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
        }               
    }
    else
    {
        for (int y = 0, x = 0; y < data.Length; ++y, ++x) 
        { 
            b = ((byte)(data[y] >> 4)); 
            c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
            b = ((byte)(data[y] & 0xF)); 
            c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
        }
    }
    return String.Concat("0x",new string(c));
}

It returns this:

True
0xDCBAABCDFFFE1608

which is the exact hex that went into the byte array.

For example if parent contrainer has height: 200, then

Container(
            decoration: BoxDecoration(
              image: DecorationImage(
                image: NetworkImage('url'),
                fit: BoxFit.cover,
              ),
            ),
          ),

General rule is the following:

• If select contains single expression and it's an entity, then result is that entity
• If select contains single expression and it's a primitive, then result is that primitive
• If select contains multiple expressions, then result is Object[] containing the corresponding primitives/entities

So, in your case list is a List<Object[]>.

How is this different from the following?

This line of code here:

String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));

constructs a new String object (i.e. a copy of oldString), while this line of code:

String newString = oldString;

declares a new variable of type java.lang.String and initializes it to refer to the same String object as the variable oldString.

Is there any scenario in which the two lines will have different outputs?

Absolutely:

String newString = oldString;
boolean isSameInstance = newString == oldString; // isSameInstance == true

vs.

String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));
 // isSameInstance == false (in most cases)    
boolean isSameInstance = newString == oldString;

a_horse_with_no_name (see comment) is right of course. The equivalent of

String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));

is

String newString = new String(oldString);

minus the subtle difference wrt the encoding that Peter Lawrey explains in his answer.
