This question is 12 years old but it still needs to be given a better answer. As few noted in the comments and contrarily to what all answers pretend it would certainly make sense to have static abstract methods in C#. As philosopher Daniel Dennett put it, a failure of imagination is not an insight into necessity. There is a common mistake in not realizing that C# is not only an OOP language. A pure OOP perspective on a given concept leads to a restricted and in the current case misguided examination. Polymorphism is not only about subtying polymorphism: it also includes parametric polymorphism (aka generic programming) and C# has been supporting this for a long time now. Within this additional paradigm, abstract classes (and most types) are not only used to type instances. They can also be used as bounds for generic parameters; something that has been understood by users of certain languages (like for example Haskell, but also more recently Scala, Rust or Swift) for years.

In this context you may want to do something like this:

void Catch<TAnimal>() where TAnimal : Animal
{
    string scientificName = TAnimal.ScientificName; // abstract static property
    Console.WriteLine($"Let's catch some {scientificName}");
    …
}

And here the capacity to express static members that can be specialized by subclasses totally makes sense!

Unfortunately C# does not allow abstract static members but I'd like to propose a pattern that can emulate them reasonably well. This pattern is not perfect (it imposes some restrictions on inheritance) but as far as I can tell it is typesafe.

The main idea is to associate an abstract companion class (here SpeciesFor<TAnimal>) to the one that should contain abstract members (here Animal):

public abstract class SpeciesFor<TAnimal> where TAnimal : Animal
{
    public static SpeciesFor<TAnimal> Instance { get { … } }

    // abstract "static" members

    public abstract string ScientificName { get; }
    
    …
}

public abstract class Animal { … }

Now we would like to make this work:

void Catch<TAnimal>() where TAnimal : Animal
{
    string scientificName = SpeciesFor<TAnimal>.Instance.ScientificName;
    Console.WriteLine($"Let's catch some {scientificName}");
    …
}

Of course we have two problems to solve:

1. How do we allow and force an implementer of a subclass of Animal to associate a specific instance of SpeciesFor<TAnimal> to this subclass?
2. How does the property SpeciesFor<TAnimal>.Instance retrieve this information?

Here is how we can solve 1:

public abstract class Animal<TSelf> where TSelf : Animal<TSelf>
{
    private Animal(…) {}
    
    public abstract class OfSpecies<TSpecies> : Animal<TSelf>
        where TSpecies : SpeciesFor<TSelf>, new()
    {
        protected OfSpecies(…) : base(…) { }
    }
    
    …
}

By making the constructor of Animal<TSelf> private we make sure that all its subclasses are also subclasses of inner class Animal<TSelf>.OfSpecies<TSpecies>. So these subclasses must specify a TSpecies type that has a new() bound.

For 2 we can provide the following implementation:

public abstract class SpeciesFor<TAnimal> where TAnimal : Animal<TAnimal>
{
    private static SpeciesFor<TAnimal> _instance;

    public static SpeciesFor<TAnimal> Instance => _instance ??= MakeInstance();

    private static SpeciesFor<TAnimal> MakeInstance()
    {
        Type t = typeof(TAnimal);
        while (true)
        {
            if (t.IsConstructedGenericType
                    && t.GetGenericTypeDefinition() == typeof(Animal<>.OfSpecies<>))
                return (SpeciesFor<TAnimal>)Activator.CreateInstance(t.GenericTypeArguments[1]);
            t = t.BaseType;
            if (t == null)
                throw new InvalidProgramException();
        }
    }

    // abstract "static" members

    public abstract string ScientificName { get; }
    
    …
}

How can we be sure that the reflection code inside MakeInstance() never throws? As we've already said, almost all classes within the hierarchy of Animal<TSelf> are also subclasses of Animal<TSelf>.OfSpecies<TSpecies>. So we know that for these classes a specific TSpecies must be provided. This type is also necessarily constructible thanks to constraint : new(). But this still leaves abstract types like Animal<Something> that have no associated species. Now we can convince ourself that the curiously recurring template pattern where TAnimal : Animal<TAnimal> makes it impossible to write SpeciesFor<Animal<Something>>.Instance as type Animal<Something> is never a subtype of Animal<Animal<Something>>.

Et voilà:

public class CatSpecies : SpeciesFor<Cat>
{
    // overriden "static" members

    public override string ScientificName => "Felis catus";
    public override Cat CreateInVivoFromDnaTrappedInAmber() { … }
    public override Cat Clone(Cat a) { … }
    public override Cat Breed(Cat a1, Cat a2) { … }
}

public class Cat : Animal<Cat>.OfSpecies<CatSpecies>
{
    // overriden members

    public override string CuteName { get { … } }
}

public class DogSpecies : SpeciesFor<Dog>
{
    // overriden "static" members

    public override string ScientificName => "Canis lupus familiaris";
    public override Dog CreateInVivoFromDnaTrappedInAmber() { … }
    public override Dog Clone(Dog a) { … }
    public override Dog Breed(Dog a1, Dog a2) { … }
}

public class Dog : Animal<Dog>.OfSpecies<DogSpecies>
{
    // overriden members

    public override string CuteName { get { … } }
}

public class Program
{
    public static void Main()
    {
        ConductCrazyScientificExperimentsWith<Cat>();
        ConductCrazyScientificExperimentsWith<Dog>();
        ConductCrazyScientificExperimentsWith<Tyranosaurus>();
        ConductCrazyScientificExperimentsWith<Wyvern>();
    }
    
    public static void ConductCrazyScientificExperimentsWith<TAnimal>()
        where TAnimal : Animal<TAnimal>
    {
        // Look Ma! No animal instance polymorphism!
        
        TAnimal a2039 = SpeciesFor<TAnimal>.Instance.CreateInVivoFromDnaTrappedInAmber();
        TAnimal a2988 = SpeciesFor<TAnimal>.Instance.CreateInVivoFromDnaTrappedInAmber();
        TAnimal a0400 = SpeciesFor<TAnimal>.Instance.Clone(a2988);
        TAnimal a9477 = SpeciesFor<TAnimal>.Instance.Breed(a0400, a2039);
        TAnimal a9404 = SpeciesFor<TAnimal>.Instance.Breed(a2988, a9477);
        
        Console.WriteLine(
            "The confederation of mad scientists is happy to announce the birth " +
            $"of {a9404.CuteName}, our new {SpeciesFor<TAnimal>.Instance.ScientificName}.");
    }
}

A limitation of this pattern is that it is not possible (as far as I can tell) to extend the class hierarchy in a satifying manner. For example we cannot introduce an intermediary Mammal class associated to a MammalClass companion. Another is that it does not work for static members in interfaces which would be more flexible than abstract classes.

Void is an incomplete type which, by definition, can't be an lvalue. That means it can't get assigned a value.

So it also can't hold any value.

It just doesn't.

The best way to fix this is:

sign = lambda x: bool(x > 0) - bool(x < 0)

This actually has nothing to do with default values, other than that it often comes up as an unexpected behaviour when you write functions with mutable default values.

>>> def foo(a):
    a.append(5)
    print a

>>> a  = [5]
>>> foo(a)
[5, 5]
>>> foo(a)
[5, 5, 5]
>>> foo(a)
[5, 5, 5, 5]
>>> foo(a)
[5, 5, 5, 5, 5]

No default values in sight in this code, but you get exactly the same problem.

The problem is that foo is modifying a mutable variable passed in from the caller, when the caller doesn't expect this. Code like this would be fine if the function was called something like append_5; then the caller would be calling the function in order to modify the value they pass in, and the behaviour would be expected. But such a function would be very unlikely to take a default argument, and probably wouldn't return the list (since the caller already has a reference to that list; the one it just passed in).

Your original foo, with a default argument, shouldn't be modifying a whether it was explicitly passed in or got the default value. Your code should leave mutable arguments alone unless it is clear from the context/name/documentation that the arguments are supposed to be modified. Using mutable values passed in as arguments as local temporaries is an extremely bad idea, whether we're in Python or not and whether there are default arguments involved or not.

If you need to destructively manipulate a local temporary in the course of computing something, and you need to start your manipulation from an argument value, you need to make a copy.

I've heard stories that they were to be included close to the orignal Java release. Oak was the precursor to Java, and in some spec documents there was mention of usigned values. Unfortunately these never made it into the Java language. As far as anyone has been able to figure out they just didn't get implemented, likely due to a time constraint.

Java does not support multiple inheritance , multipath and hybrid inheritance because of ambiguity problem:

 Scenario for multiple inheritance: Let us take class A , class B , class C. class A has alphabet(); method , class B has also alphabet(); method. Now class C extends A, B and we are creating object to the subclass i.e., class C , so  C ob = new C(); Then if you want call those methods ob.alphabet(); which class method takes ? is class A method or class B method ?  So in the JVM level ambiguity problem occurred. Thus Java does not support multiple inheritance.

Dim originally (in BASIC) stood for Dimension, as it was used to define the dimensions of an array.

(The original implementation of BASIC was Dartmouth BASIC, which descended from FORTRAN, where DIMENSION is spelled out.)

Nowadays, Dim is used to define any variable, not just arrays, so its meaning is not intuitive anymore.

Lua is lightweight scripting language which want to smaller as possible. For example, many unary operation such as pre/post increment is not available

Instead of continue, you can use goto like

arr = {1,2,3,45,6,7,8}
for key,val in ipairs(arr) do
  if val > 6 then
     goto skip_to_next
  end
     # perform some calculation
  ::skip_to_next::
end

The reason is that the compiler has to actually see the definition in order to be able to drop it in in place of the call.

Remember that C and C++ use a very simplistic compilation model, where the compiler always only sees one translation unit at a time. (This fails for export, which is the main reason only one vendor actually implemented it.)

It is Nanny. I feel .Net got this one right - it raises a warning for unreachable code, but not an error. It is good to be warned about it, but I see no reason to prevent compilation (especially during debugging sessions where it is nice to throw a return in to bypass some code).

As stated already within another answer it is not recommended to catch a NullPointerException. However you definitely could catch it, like the following example shows.

public class Testclass{

    public static void main(String[] args) {
        try {
            doSomething();
        } catch (NullPointerException e) {
            System.out.print("Caught the NullPointerException");
        }
    }

    public static void doSomething() {
        String nullString = null;
        nullString.endsWith("test");
    }
}

Although a NPE can be caught you definitely shouldn't do that but fix the initial issue, which is the Check_Circular method.

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));

You can use a plugin available here..

https://plugins.jquery.com/cookie/

and then to write a cookie do $.cookie("test", 1);

to access the set cookie do $.cookie("test");

Easiest way is to throw a ResponseStatusException

    @RequestMapping(value = "/matches/{matchId}", produces = "application/json")
    @ResponseBody
    public String match(@PathVariable String matchId, @RequestBody String body) {
        String json = matchService.getMatchJson(matchId);
        if (json == null) {
            throw new ResponseStatusException(HttpStatus.NOT_FOUND);
        }
        return json;
    }

As of .NET Core 2.0, the constructor Dictionary<TKey,TValue>(IEnumerable<KeyValuePair<TKey,TValue>>) now exists.

I was asked to build a java system that will have the ability to load new code while running

You might want to base your system on OSGi (or at least take a lot at it), which was made for exactly this situation.

Messing with classloaders is really tricky business, mostly because of how class visibility works, and you do not want to run into hard-to-debug problems later on. For example, Class.forName(), which is widely used in many libraries does not work too well on a fragmented classloader space.

My solution. It may be slower on performance:

a = pd.concat(df[df[c] == 1] for c in df.columns if c.startswith('foo'))
a.sort_index()


   bar.baz  foo.aa  foo.bars  foo.fighters  foo.fox foo.manchu nas.foo
0      5.0     1.0         0             0        2         NA      NA
1      5.0     2.1         0             1        4          0       0
2      6.0     NaN         0           NaN        1          0       1
5      6.8     6.8         1             0        5          0       0

The click event is not bound to your new element, use a jQuery.on to handle the click.

I had same requirement.

I have used the below way to get it.

I had session scoped bean.

@ManagedBean(name="mb")
@SessionScopedpublic 
class ManagedBean {
     --------
}

I have used the below code in my servlet doPost() method.

ManagedBean mb = (ManagedBean) request.getSession().getAttribute("mb");

it solved my problem.

Simple Steps

1. 1 Open SQL Server Configuration Manager
2. Under SQL Server Services Select Your Server
3. Right Click and Select Properties
4. Log on Tab Change Built-in-account tick
5. in the drop down list select Network Service
6. Apply and start The service

Ok to generalize the technique of how many bits you need to represent a number is done this way. You have R symbols for a representation and you want to know how many bits, solve this equation R=2^n or log2(R)=n. Where n is the numbers of bits and R is the number of symbols for the representation.

For the decimal number system R=9 so we solve 9=2^n, the answer is 3.17 bits per decimal digit. Thus a 3 digit number will need 9.51 bits or 10. A 1000 digit number needs 3170 bits

In case this can help anyone, here's simple CSS as a jumping off point. Turns it into a basic rounded square big enough for thumbs with a toggled background color.

input[type='checkbox'] {_x000D_
    -webkit-appearance:none;_x000D_
    width:30px;_x000D_
    height:30px;_x000D_
    background:white;_x000D_
    border-radius:5px;_x000D_
    border:2px solid #555;_x000D_
}_x000D_
input[type='checkbox']:checked {_x000D_
    background: #abd;_x000D_
}

<input type="checkbox" />

For Example you have the package "com.abc" and you have multiple packages inside it, You can use like

@ComponentScan("com.abc")

I haven't tested the email part of this (my test box does not send email) but I think it will work.

<?php

--$s--", "MIME-Version: 1.0\r\nContent-Type: multipart/mixed; boundary=\"$s\"");
exit;
}
?>
<form method="post" enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<textarea name="m"></textarea><br>

None of the methods provided in the answers worked for me. I found the following way works if your android version is 5.0 or above:

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

                    ViewOutlineProvider provider = new ViewOutlineProvider() {
                        @Override
                        public void getOutline(View view, Outline outline) {
                            int curveRadius = 24;
                            outline.setRoundRect(0, 0, view.getWidth(), (view.getHeight()+curveRadius), curveRadius);
                        }
                    };
                    imageview.setOutlineProvider(provider);
                    imageview.setClipToOutline(true);
        }   

No xml shapes to be defined, and the code above create corners only for top, which normal methods won't work. If you need 4 corners to be rounded, remove:

"+ curveRadius"  

From the parameter for bottom in setRoundRect. You can further expand the shape to any others by specifying outlines that suit your needs. Check out the following link:

Android Developer Documentation.

You can use strlen. Size is determined by the terminating null-character, so passed string should be valid.

If you want to get size of memory buffer, that contains your string, and you have pointer to it:

• If it is dynamic array(created with malloc), it is impossible to get it size, since compiler doesn't know what pointer is pointing at. (check this)
• If it is static array, you can use sizeof to get its size.

If you are confused about difference between dynamic and static arrays, check this.

Okay, since it already "leaked": You're missing zero, so the correct answer is 512 (511 is the greatest one, but it's 0 to 511, not 1 to 511).

By the way, an good followup exercise would be to generalize this:

How many different values can be represented in n binary digits (bits)?

I found another solution elsewhere; that is, to use

upper(@yourString)

but everyone here is saying that, in SQL Server, it doesn't matter because it's ignoring case anyway? I'm pretty sure our database is case-sensitive.

check this link, in very simple via the convertView, we can get the layout of a row which will be displayed in listview (which is the parentView).

View v = convertView;

if (v == null) {

    LayoutInflater vi;
    vi = LayoutInflater.from(getContext());
    v = vi.inflate(R.layout.itemlistrow, null);

}

using the position, you can get the objects of the List<Item>.

Item p = items.get(position);

after that we'll have to set the desired details of the object to the identified form widgets.

if (p != null) {

    TextView tt = (TextView) v.findViewById(R.id.id);
    TextView tt1 = (TextView) v.findViewById(R.id.categoryId);
    TextView tt3 = (TextView) v.findViewById(R.id.description);

    if (tt != null) {
        tt.setText(p.getId());
    }
    if (tt1 != null) {

        tt1.setText(p.getCategory().getId());
    }
    if (tt3 != null) {

        tt3.setText(p.getDescription());
    }
}

then it will return the constructed view which will be attached to the parentView (which is a ListView/GridView).

1. find the folder: sudo find / -name "mysql_config" (assume it's "/opt/local/lib/mysql5/bin")

2. add it into PATH:export PATH:export PATH=/opt/local/lib/mysql5/bin:$PATH

3. install it again

You cannot define a free function inside another in C++.

You can use array.slice(0,1) // First index is removed and array is returned.

This has already been mentioned, but here is a way to place the code within a method:

    public static String getMonthName(int monthIndex) {
         return new DateFormatSymbols().getMonths()[monthIndex].toString();
    }

or if you wanted to create a better error than an ArrayIndexOutOfBoundsException:

    public static String getMonthName(int monthIndex) {
        //since this is zero based, 11 = December
        if (monthIndex < 0 || monthIndex > 11 ) {
            throw new IllegalArgumentException(monthIndex + " is not a valid month index.");
        }
        return new DateFormatSymbols().getMonths()[monthIndex].toString();
    }

I do not believe you can set the style programatically. To get around this you can create a template layout xml file with the style assigned, for example in res/layout create tvtemplate.xml as with the following content:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="This is a template"
        style="@style/my_style" />

then inflate this to instantiate your new TextView:

TextView myText = (TextView)getLayoutInflater().inflate(R.layout.tvtemplate, null);

Hope this helps.

You can use javascript for this purpose, this way:

1. first you set the CSS for the 'normal' class and for the 'active' class
2. then you give to your element the id 'MyElement'
3. and now you make your condition in JavaScript, something like the example below... (you can run it, change the value of myVar to 5 and you will see how it works)

var myVar = 4;_x000D_
_x000D_
if(myVar == 5){_x000D_
  document.getElementById("MyElement").className = "active";_x000D_
}_x000D_
else{_x000D_
  document.getElementById("MyElement").className = "normal";_x000D_
}

.active{_x000D_
  background-position : 150px 8px;_x000D_
  background-color: black;_x000D_
}_x000D_
.normal{_x000D_
  background-position : 4px 8px; _x000D_
  background-color: green;_x000D_
}_x000D_
div{_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  }

<div id="MyElement">_x000D_
  _x000D_
  </div>

use the runas command. But, I don't think you can email a .bat file easily.

I to had a similar doubt what I got to know was getActivity() returns the Activity to which the fragment is associated.

The getActivity() method is used generally in static fragment as the associated activity will not be static and non static member cannot be used in static member.

#!/usr/bin/python2
import sys, subprocess, threading
proc = subprocess.Popen(sys.argv[2:])
timer = threading.Timer(float(sys.argv[1]), proc.terminate)

timer.cancel()
exit(proc.returncode)

Have you tried using the stream_context_set_option() method ?

$context = stream_context_create();
$result = stream_context_set_option($context, 'ssl', 'local_cert', '/etc/ssl/certs/cacert.pem');
$fp = fsockopen($host, $port, $errno, $errstr, 20, $context);

In addition, try file_get_contents() for the pem file, to make sure you have permissions to access it, and make sure the host name matches the certificate.

For primitive array types, you would have to write a reverse sort algorithm:

Alternatively, you can convert your int[] to Integer[] and write a comparator:

public class IntegerComparator implements Comparator<Integer> {

    @Override
    public int compare(Integer o1, Integer o2) {
        return o2.compareTo(o1);
    }
}

or use Collections.reverseOrder() since it only works on non-primitive array types.

and finally,

Integer[] a2 = convertPrimitiveArrayToBoxableTypeArray(a1);
Arrays.sort(a2, new IntegerComparator()); // OR
// Arrays.sort(a2, Collections.reverseOrder());

//Unbox the array to primitive type
a1 = convertBoxableTypeArrayToPrimitiveTypeArray(a2);

As of now (March 2018) & version 1.21.0, you can go to Settings, search for 'zoom' and change "editor.mouseWheelZoom": false which is false by default to true. This will allow to zoom in/out on VS Code using control button and mouse - ctrl + scrollUp/scrollDown. For changing the fontSize of the overall working space/screen of VS Code, refer to Alegozalves's answer above.

(Edited.) There are two reasons why it doesn't compile: You're missing a semi-colon at the end of this statement:

array3[i]=e1

Also the findOut method doesn't return any value if the array length is 0. Adding a return 0; at the end of the method will make it compile. I've no idea if that will make it do what you want though, as I've no idea what you want it to do.

Float right the text you want to appear on the right, and in the markup make sure that this text and its surrounding span occurs before the text that should be on the left. If it doesn't occur first, you may have problems with the floated text appearing on a different line.

Note that this works for any line, not just the top and bottom corners.

Example

Just try it like this:

<!-- A light one -->
<nav class="navbar navbar-default" role="navigation"></nav>
<!-- A dark one -->
<nav class="navbar navbar-inverse" role="navigation"></nav>

Swift 2.0: Coloring Navigation Bar & buttons

navigationController?.navigationBar.barTintColor = UIColor.blueColor()
navigationController?.navigationBar.tintColor = UIColor.whiteColor()
navigationController!.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.whiteColor()]

Is just this:

int strcmp(char *str1, char *str2){
    while( (*str1 == *str2) && (*str1 != 0) ){
        ++*str1;
        ++*str2;
    }
    return (*str1-*str2);
}

if you want more fast, you can add "register " before type, like this: register char

then, like this:

int strcmp(register char *str1, register char *str2){
    while( (*str1 == *str2) && (*str1 != 0) ){
        ++*str1;
        ++*str2;
    }
    return (*str1-*str2);
}

this way, if possible, the register of the ALU are used.

You can check iOS Version and simply set the tint color of Navigation bar.

if (SYSTEM_VERSION_LESS_THAN(@"7.0")) {
    self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
}else{

    self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
    self.navigationItem.leftBarButtonItem.tintColor = [UIColor whiteColor];
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}

This might sound strange but you can remove next line by copying the whole text and pasting it in firefox search bar, and then re-pasting it in notepad++

Maybe this is not the answer you needed, but I encountered similar problem, so I decided to put it here.

I needed to convert 500 xml files to UTF8 via Notepad++. Why Notepad++? When I used the option "Encode in UTF8" (many other converters use the same logic) it messed up all special characters, so I had to use "Convert to UTF8" explicitly.

Here some simple steps to convert multiple files via Notepad++ without messing up with special characters (for ex. diacritical marks).

1. Run Notepad++ and then open menu Plugins->Plugin Manager->Show Plugin Manager
2. Install Python Script. When plugin is installed, restart the application.
3. Choose menu Plugins->Python Script->New script.
4. Choose its name, and then past the following code:

convertToUTF8.py

import os
import sys
from Npp import notepad # import it first!

filePathSrc="C:\\Users\\" # Path to the folder with files to convert
for root, dirs, files in os.walk(filePathSrc):
    for fn in files: 
        if fn[-4:] == '.xml': # Specify type of the files
            notepad.open(root + "\\" + fn)      
            notepad.runMenuCommand("Encoding", "Convert to UTF-8")
            # notepad.save()
            # if you try to save/replace the file, an annoying confirmation window would popup.
            notepad.saveAs("{}{}".format(fn[:-4], '_utf8.xml')) 
            notepad.close()

After all, run the script

I stumbled upon this old listing pondering this same question. My band-aid for this same question was to make my header text into a link. I then changed the color and removed text decoration with CSS. Now to make the entire header picture a link, I expanded the padding of the anchor tag until it reached close to the edge of the header image.... This worked to my satisfaction, and I figured i would share.

Use dev.new(). (See this related question.)

plot(1:10)
dev.new(width=5, height=4)
plot(1:20)

To be more specific which units are used:

dev.new(width=5, height=4, unit="in")
plot(1:20)
dev.new(width = 550, height = 330, unit = "px")
plot(1:15)

For Rstudio, add dev.new(width=5,height=4,noRStudioGD = TRUE)

Just replacing "Please enter your name" to your desired content would do the job. Am I missing something?

All answers I've encountered here only check if the element is positioned inside the current viewport. But that doesn't mean that it is visible.
What if the given element is inside a div with overflowing content, and it is scrolled out of view?

To solve that, you'd have to check if the element is contained by all parents.
My solution does exactly that:

It also allows you to specify how much of the element has to be visible.

Element.prototype.isVisible = function(percentX, percentY){
    var tolerance = 0.01;   //needed because the rects returned by getBoundingClientRect provide the position up to 10 decimals
    if(percentX == null){
        percentX = 100;
    }
    if(percentY == null){
        percentY = 100;
    }

    var elementRect = this.getBoundingClientRect();
    var parentRects = [];
    var element = this;

    while(element.parentElement != null){
        parentRects.push(element.parentElement.getBoundingClientRect());
        element = element.parentElement;
    }

    var visibleInAllParents = parentRects.every(function(parentRect){
        var visiblePixelX = Math.min(elementRect.right, parentRect.right) - Math.max(elementRect.left, parentRect.left);
        var visiblePixelY = Math.min(elementRect.bottom, parentRect.bottom) - Math.max(elementRect.top, parentRect.top);
        var visiblePercentageX = visiblePixelX / elementRect.width * 100;
        var visiblePercentageY = visiblePixelY / elementRect.height * 100;
        return visiblePercentageX + tolerance > percentX && visiblePercentageY + tolerance > percentY;
    });
    return visibleInAllParents;
};

This solution ignored the fact that elements may not be visible due to other facts, like opacity: 0.

I have tested this solution in Chrome and Internet Explorer 11.

This solution demonstrates how to transform data with Spark native functions which are better than UDFs. It also demonstrates how dropDuplicates which is more suitable than distinct for certain queries.

Suppose you have this DataFrame:

+-------+-------------+
|country|    continent|
+-------+-------------+
|  china|         asia|
| brazil|south america|
| france|       europe|
|  china|         asia|
+-------+-------------+

Here's how to take all the distinct countries and run a transformation:

df
  .select("country")
  .distinct
  .withColumn("country", concat(col("country"), lit(" is fun!")))
  .show()

+--------------+
|       country|
+--------------+
|brazil is fun!|
|france is fun!|
| china is fun!|
+--------------+

You can use dropDuplicates instead of distinct if you don't want to lose the continent information:

df
  .dropDuplicates("country")
  .withColumn("description", concat(col("country"), lit(" is a country in "), col("continent")))
  .show(false)

+-------+-------------+------------------------------------+
|country|continent    |description                         |
+-------+-------------+------------------------------------+
|brazil |south america|brazil is a country in south america|
|france |europe       |france is a country in europe       |
|china  |asia         |china is a country in asia          |
+-------+-------------+------------------------------------+

See here for more information about filtering DataFrames and here for more information on dropping duplicates.

Ultimately, you'll want to wrap your transformation logic in custom transformations that can be chained with the Dataset#transform method.

Linux Kernel Development by Robert Love (Chapter 12, page 244 in 3rd edition) answers this very clearly.

Yes, physically contiguous memory is not required in many of the cases. Main reason for kmalloc being used more than vmalloc in kernel is performance. The book explains, when big memory chunks are allocated using vmalloc, kernel has to map the physically non-contiguous chunks (pages) into a single contiguous virtual memory region. Since the memory is virtually contiguous and physically non-contiguous, several virtual-to-physical address mappings will have to be added to the page table. And in the worst case, there will be (size of buffer/page size) number of mappings added to the page table.

This also adds pressure on TLB (the cache entries storing recent virtual to physical address mappings) when accessing this buffer. This can lead to thrashing.

Well, as now in Jan, 2018, the best way for this is to use apache's BooleanUtils.toBoolean.

This will convert any boolean like string to boolean, e.g. Y, yes, true, N, no, false, etc.

Really handy!

I also had the same issue. I also wanted so users could take photos easily while picking photos from the gallery. Couldn't find a native way of doing this therefore I decided to make an opensource project. It is much like MultipleImagePick but just better way of implementing it.

https://github.com/giljulio/android-multiple-image-picker

private static final RESULT_CODE_PICKER_IMAGES = 9000;


Intent intent = new Intent(this, SmartImagePicker.class);
startActivityForResult(intent, RESULT_CODE_PICKER_IMAGES);


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode){
        case RESULT_CODE_PICKER_IMAGES:
            if(resultCode == Activity.RESULT_OK){
                Parcelable[] parcelableUris = data.getParcelableArrayExtra(ImagePickerActivity.TAG_IMAGE_URI);

                //Java doesn't allow array casting, this is a little hack
                Uri[] uris = new Uri[parcelableUris.length];
                System.arraycopy(parcelableUris, 0, uris, 0, parcelableUris.length);

                //Do something with the uris array
            }
            break;

        default:
            super.onActivityResult(requestCode, resultCode, data);
            break;
    }
}

You can just substract two date objects.

var d1 = new Date(); //"now"
var d2 = new Date("2011/02/01")  // some date
var diff = Math.abs(d1-d2);  // difference in milliseconds

Its best practice to have TOP 1 1 always.

What if I use SELECT 1 -> If condition matches more than one record then your query will fetch all the columns records and returns 1.

What if I use SELECT TOP 1 1 -> If condition matches more than one record also, it will just fetch the existence of any row (with a self 1-valued column) and returns 1.

IF EXISTS (SELECT TOP 1 1 FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx') 
BEGIN
   SELECT 1 
END
ELSE
BEGIN
    SELECT 2
END

Heres another approach.

HTML:

<input type='text' id="pointspossible" class="clsInput" />
<input type='text' id="pointsgiven"  class="clsInput" />
<button id="btnCalculate">Calculate</button>
<input type='text' id="pointsperc" disabled/>

JS Code:

function isNumeric(n) {
    return !isNaN(parseFloat(n)) && isFinite(n);
}


$('#btnCalculate').on('click', function() {
    var a = $('#pointspossible').val().replace(/ +/g, "");
    var b = $('#pointsgiven').val().replace(/ +/g, "");
    var perc = "0";
    if (a.length > 0 && b.length > 0) {
        if (isNumeric(a) && isNumeric(b)) {
            perc = a / b * 100;
        }
    }    
    $('#pointsperc').val(perc).toFixed(3);
});

For reference: I had this error when trying to do an unattended VS 2013 install in a windowsservercore docker container:

.\vs_professional.exe /Q

reason turned out to be having the installation files on a docker volume, copying to the disk of the container solved it.

It sounds like the server is having trouble handling POST requests (get and post are verbs). I don't know, how or why someone would configure a server to ignore post requests, but the only solution would be to fix the server, or change your app to use get requests.

It used to be generally recommended best practice¹ to use pass by const ref for all types, except for builtin types (char, int, double, etc.), for iterators and for function objects (lambdas, classes deriving from std::*_function).

This was especially true before the existence of move semantics. The reason is simple: if you passed by value, a copy of the object had to be made and, except for very small objects, this is always more expensive than passing a reference.

With C++11, we have gained move semantics. In a nutshell, move semantics permit that, in some cases, an object can be passed “by value” without copying it. In particular, this is the case when the object that you are passing is an rvalue.

In itself, moving an object is still at least as expensive as passing by reference. However, in many cases a function will internally copy an object anyway — i.e. it will take ownership of the argument.²

In these situations we have the following (simplified) trade-off:

1. We can pass the object by reference, then copy internally.
2. We can pass the object by value.

“Pass by value” still causes the object to be copied, unless the object is an rvalue. In the case of an rvalue, the object can be moved instead, so that the second case is suddenly no longer “copy, then move” but “move, then (potentially) move again”.

For large objects that implement proper move constructors (such as vectors, strings …), the second case is then vastly more efficient than the first. Therefore, it is recommended to use pass by value if the function takes ownership of the argument, and if the object type supports efficient moving.

A historical note:

In fact, any modern compiler should be able to figure out when passing by value is expensive, and implicitly convert the call to use a const ref if possible.

In theory. In practice, compilers can’t always change this without breaking the function’s binary interface. In some special cases (when the function is inlined) the copy will actually be elided if the compiler can figure out that the original object won’t be changed through the actions in the function.

But in general the compiler can’t determine this, and the advent of move semantics in C++ has made this optimisation much less relevant.

¹ E.g. in Scott Meyers, Effective C++.

² This is especially often true for object constructors, which may take arguments and store them internally to be part of the constructed object’s state.

Sometimes using only the line below throws me an Exception,

String text = listView1.SelectedItems[0].Text; 

so I use this code below:

private void listView1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    if (listView1.SelectedIndices.Count <= 0) 
    { 
        return; 
    } 
    int intselectedindex = listView1.SelectedIndices[0]; 
    if (intselectedindex >= 0) 
    {
        String text = listView1.Items[intselectedindex].Text;

        //do something
        //MessageBox.Show(listView1.Items[intselectedindex].Text); 
    } 
}

Use os.path.join(). Example: os.path.join(pathfile,"output","log.txt").

In your code that would be: rootTree.write(os.path.join(pathfile,"output","log.txt"))

Using MS SQL Server 2008, in DELETE dialog with Close connection options, this is the generated script, I guess it is the best:

EXEC msdb.dbo.sp_delete_database_backuphistory @database_name = N'YOUR_DATABASE_NAME'
GO
USE [master]
GO
ALTER DATABASE [YOUR_DATABASE_NAME] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE
GO
USE [master]
GO
/****** Object:  Database [YOUR_DATABASE_NAME]    Script Date: 01/08/2014 21:36:29 ******/
DROP DATABASE [YOUR_DATABASE_NAME]
GO

What helped me were the suggestions by @carlspring (create a settings.xml to configure your http proxy):

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

AND then refreshing eclipse project maven as suggested by @Peter T :

"Force update of Snapshots/Releases" in Eclipse. this clears all errors. So right click on project -> Maven -> update project, then check the above option -> Ok. Hope this helps you.

maybe doesnt exists javaee-api-7.0.jar. download this jar and on your project right clik

1. on your project right click
2. build path
3. Configure build path
4. Add external Jars
5. javaee-api-7.0.jar choose
6. Apply and finish

You must note however that the Array.filter is not supported in all browser so, you must to prototyped:

//This prototype is provided by the Mozilla foundation and
//is distributed under the MIT license.
//http://www.ibiblio.org/pub/Linux/LICENSES/mit.license

if (!Array.prototype.filter)
{
    Array.prototype.filter = function(fun /*, thisp*/)
    {
        var len = this.length;

        if (typeof fun != "function")
            throw new TypeError();

        var res = new Array();
        var thisp = arguments[1];

        for (var i = 0; i < len; i++)
        {
            if (i in this)
            {
                var val = this[i]; // in case fun mutates this

                if (fun.call(thisp, val, i, this))
                   res.push(val);
            }
        }

        return res;
    };
}

And doing so, you can prototype any method you may need.

change:

$("input:text").change(function() {
    var value=$("input:text").val();
    alert(value);
});

to

$("input:text").change(function() {
    var value=$("input[type=text].selector").val();
    alert(value);
});

note: selector:id,class..

This question is old, but I'm surprised why no one mentioned boost::format:

cout << (boost::format("%x") % 1234).str();  // output is: 4d2

Web Hosting Challenge

You have to remember that none of the machine configuration options are available if you are hosted on a shared server as many of us (smaller companies and individuals) are.

ASP.NET MVC Overhead

My site takes at least 30 seconds when it hasn't been hit in over 20 minutes (and the web app has been stopped). It is terrible.

Another Way to Test Performance

There's another way to test if it is your ASP.NET MVC start up or something else. Drop a normal HTML page on your site where you can hit it directly.
If the problem is related to ASP.NET MVC start up then the HTML page will render almost immediately even when the web app hasn't been started.
That's how I first recognized that the problem was in the ASP.NET MVC startup. I loaded an HTML page at any time and it would load blazing fast. Then, after hitting that HTML page I'd hit one of my ASP.NET MVC URLs and I'd get the Chrome message "Waiting for raddev.us..."

Another Test With Helpful Script

After that I wrote a LINQPad (check out http://linqpad.net for more) script that would hit my web site every 8 minutes (less than the time for the app to unload -- which should be 20 minutes) and I let it run for hours.

While the script was running I hit my web site and every time my site came up blazingly fast. This gives me a good idea that most likely the slowness I was experiencing was because of ASP.NET MVC startup times.

Get LinqPad and you can run the following script -- just change the URL to your own and let it run and you can test this easily. Good luck.

NOTE: In LinqPad you'll need to press F4 and add a reference to System.Net to add the library which will retrieve your page.

ALSO : make sure you change the String URL variable to point at a URL that will load a route from your ASP.NET MVC site so the engine will run.

System.Timers.Timer webKeepAlive = new System.Timers.Timer();
Int64 counter = 0;
void Main()
{
    webKeepAlive.Interval = 5000;
    webKeepAlive.Elapsed += WebKeepAlive_Elapsed;
    webKeepAlive.Start();
}

private void WebKeepAlive_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    webKeepAlive.Stop();
    try
    {
        // ONLY the first time it retrieves the content it will print the string
        String finalHtml = GetWebContent();
        if (counter < 1)
        {
            Console.WriteLine(finalHtml);
        }
        counter++;
    }
    finally
    {
        webKeepAlive.Interval = 480000; // every 8 minutes
        webKeepAlive.Start();
    }
}

public String GetWebContent()
{
    try
    {
    String URL = "http://YOURURL.COM";
    WebRequest request = WebRequest.Create(URL);
    WebResponse response = request.GetResponse();
    Stream data = response.GetResponseStream();
    string html = String.Empty;
    using (StreamReader sr = new StreamReader(data))
    {
        html = sr.ReadToEnd();
    }
    Console.WriteLine (String.Format("{0} : success",DateTime.Now));
    return html;
    }
    catch (Exception ex)
    {
        Console.WriteLine (String.Format("{0} -- GetWebContent() : {1}",DateTime.Now,ex.Message));
        return "fail";
    }
}

If you are using one of those js libraries to insert Flash, I suggest adding plain object embed tag inside of <noscript/>.

$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
    $("#success-alert").alert('close');
});

Where fadeTo parameters are fadeTo(speed, opacity)

I've been working kind of similar to this and I have some code that might help you. The live example is here and below, is the code I'm using for you to have it as reference.

create-page.php

<?php

// Session is started.
session_start();

// Name of the template file.
$template_file = 'couples-template.php';

// Root folder if working in subdirectory. Name is up to you ut must match with server's folder.
$base_path = '/couple/';

// Path to the directory where you store the "couples-template.php" file.
$template_path = '../template/';

// Path to the directory where php will store the auto-generated couple's pages.
$couples_path = '../couples/';

// Posted data.
$data['groom-name'] = str_replace(' ', '', $_POST['groom-name']);
$data['bride-name'] = str_replace(' ', '', $_POST['bride-name']);
// $data['groom-surname'] = $_POST['groom-surname'];
// $data['bride-surname'] = $_POST['bride-surname'];
$data['wedding-date'] = $_POST['wedding-date'];
$data['email'] = $_POST['email'];
$data['code'] = str_replace(array('/', '-', ' '), '', $_POST['wedding-date']).strtoupper(substr($data['groom-name'], 0, 1)).urlencode('&').strtoupper(substr($data['bride-name'], 0, 1));

// Data array (Should match with data above's order).
$placeholders = array('{groom-name}', '{bride-name}', '{wedding-date}', '{email}', '{code}');

// Get the couples-template.php as a string.
$template = file_get_contents($template_path.$template_file);

// Fills the template.
$new_file = str_replace($placeholders, $data, $template);

// Generates couple's URL and makes it frendly and lowercase.
$couples_url = str_replace(' ', '', strtolower($data['groom-name'].'-'.$data['bride-name'].'.php'));

// Save file into couples directory.
$fp = fopen($couples_path.$couples_url, 'w');
fwrite($fp, $new_file);
fclose($fp);

// Set the variables to pass them to success page.
$_SESSION['couples_url'] = $couples_url;
// If working in root directory.
$_SESSION['couples_path'] = str_replace('.', '', $couples_path);
// If working in a sub directory.
//$_SESSION['couples_path'] = substr_replace($base_path, '', -1).str_replace('.', '',$couples_path);

header('Location: success.php');

?>

Hope this file can help and work as reference to start and boost your project.

A functional approach:

a = [1,"A", 34, -123, "Hello", 12]
b = [0, 2, 5]

from operator import itemgetter

print(list(itemgetter(*b)(a)))
[1, 34, 12]

You could use an <a> tag with different styles:

a:link    { }
a:visited { }
a:hover   { }
a:active  { }

I'd recommend using that in conjunction with CSS sprites: https://css-tricks.com/css-sprites/

Here is a simplified function that returns a boolean and has no output pushed to stdout:

import subprocess, platform
def pingOk(sHost):
    try:
        output = subprocess.check_output("ping -{} 1 {}".format('n' if platform.system().lower()=="windows" else 'c', sHost), shell=True)

    except Exception, e:
        return False

    return True

In a case where you may be storing true / false as strings, such as in localStorage where the protocol flipped to multi object storage in 2009 & then flipped back to string only in 2011 - you can use JSON.parse to interpret to boolean on the fly:

this.sidebar = !JSON.parse(this.sidebar);

The solution found here helped us to update master to a previous commit that had already been pushed:

git checkout master
git reset --hard e3f1e37
git push --force origin e3f1e37:master

The key difference from the accepted answer is the commit hash "e3f1e37:" before master in the push command.

To calculate distance on Google Maps, you can use Directions API. That will be one of the easiest way to do it. To get data from Google Server, you can use Retrofit or Volley. Both has their own advantage. Take a look at following code where I have used retrofit to implement it:

private void build_retrofit_and_get_response(String type) {

    String url = "https://maps.googleapis.com/maps/";

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(url)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    RetrofitMaps service = retrofit.create(RetrofitMaps.class);

    Call<Example> call = service.getDistanceDuration("metric", origin.latitude + "," + origin.longitude,dest.latitude + "," + dest.longitude, type);

    call.enqueue(new Callback<Example>() {
        @Override
        public void onResponse(Response<Example> response, Retrofit retrofit) {

            try {
                //Remove previous line from map
                if (line != null) {
                    line.remove();
                }
                // This loop will go through all the results and add marker on each location.
                for (int i = 0; i < response.body().getRoutes().size(); i++) {
                    String distance = response.body().getRoutes().get(i).getLegs().get(i).getDistance().getText();
                    String time = response.body().getRoutes().get(i).getLegs().get(i).getDuration().getText();
                    ShowDistanceDuration.setText("Distance:" + distance + ", Duration:" + time);
                    String encodedString = response.body().getRoutes().get(0).getOverviewPolyline().getPoints();
                    List<LatLng> list = decodePoly(encodedString);
                    line = mMap.addPolyline(new PolylineOptions()
                                    .addAll(list)
                                    .width(20)
                                    .color(Color.RED)
                                    .geodesic(true)
                    );
                }
            } catch (Exception e) {
                Log.d("onResponse", "There is an error");
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(Throwable t) {
            Log.d("onFailure", t.toString());
        }
    });

}

Above is the code of function build_retrofit_and_get_response for calculating distance. Below is corresponding Retrofit Interface:

package com.androidtutorialpoint.googlemapsdistancecalculator;


import com.androidtutorialpoint.googlemapsdistancecalculator.POJO.Example;

import retrofit.Call;
import retrofit.http.GET;
import retrofit.http.Query;

public interface RetrofitMaps {


/*
 * Retrofit get annotation with our URL
 * And our method that will return us details of student.
 */
@GET("api/directions/json?key=AIzaSyC22GfkHu9FdgT9SwdCWMwKX1a4aohGifM")
Call<Example> getDistanceDuration(@Query("units") String units, @Query("origin") String origin, @Query("destination") String destination, @Query("mode") String mode);

}

I hope this explains your query. All the best :)

When doing this from DBeaver I had to go to "Connection settings" -> "SSL" tab and then :

• uncheck the "Verify server certificate"
• check the "Allow public key retrival"

This is how it looks like.

Note that this is suitable for local development only.

moment(timestamp).format('''any format''')

Or simply use

ng-show="v.hasOwnProperty('secId')"

For asynchronously calling task from Main, use

1. Task.Run() for .NET 4.5

2. Task.Factory.StartNew() for .NET 4.0 (May require Microsoft.Bcl.Async library for async and await keywords)

open the sql file on Notepad++ and ctrl + H. Then you put "utf8mb4" on search and "utf8" on replace. The issue will be fixed then.

By default Kubernetes looks in the public Docker registry to find images. If your image doesn't exist there it won't be able to pull it.

You can run a local Kubernetes registry with the registry cluster addon.

Then tag your images with localhost:5000:

docker tag aii localhost:5000/dev/aii

Push the image to the Kubernetes registry:

docker push localhost:5000/dev/aii

And change run-aii.yaml to use the localhost:5000/dev/aii image instead of aii. Now Kubernetes should be able to pull the image.

Alternatively, you can run a private Docker registry through one of the providers that offers this (AWS ECR, GCR, etc.), but if this is for local development it will be quicker and easier to get setup with a local Kubernetes Docker registry.

Update:

The preferences in Settings (Preferences) | Tools | Terminal are global.
If you use a venv for each project, remember to use current path variable and a default venv name:

"cmd.exe" /k ""%CD%\venv\Scripts\activate"" 

For Windows users: when using PyCharm with a virtual environment, you can use the /K parameter to cmd.exe to set the virtual environment automatically.

PyCharm 3 or 4: Settings, Terminal, Default shell and add /K <path-to-your-activate.bat>.

PyCharm 5: Settings, Tools, Terminal, and add /K <path-to-your-activate.bat> to Shell path.

PyCharm 2016.1 or 2016.2: Settings, Tools, Terminal, and add ""/K <path-to-your-activate.bat>"" to Shell path and add (mind the quotes). Also add quotes around cmd.exe, resulting in:

"cmd.exe" /k ""C:\mypath\my-venv\Scripts\activate.bat""

$sql = "SELECT * FROM MY_TABLE";
$result = mysqli_query($conn, $sql); // First parameter is just return of "mysqli_connect()" function
echo "<br>";
echo "<table border='1'>";
while ($row = mysqli_fetch_assoc($result)) { // Important line !!! Check summary get row on array ..
    echo "<tr>";
    foreach ($row as $field => $value) { // I you want you can right this line like this: foreach($row as $value) {
        echo "<td>" . $value . "</td>"; // I just did not use "htmlspecialchars()" function. 
    }
    echo "</tr>";
}
echo "</table>";

When I worked on Mac OS X in the lab I was able to get the terminal colors from using Terminal (rather than X11) and then editing the profile (from the Mac menu bar). The interface is a bit odd on the colors, but you have to set the modified theme as default.

Further settings worked by editing .bashrc.

I needed to delete all rows except the first and solution posted by @strat but that resulted in uncaught exception (referencing Node in context where it does not exist). The following worked for me.

var myTable = document.getElementById("myTable");
var rowCount = myTable.rows.length;
for (var x=rowCount-1; x>0; x--) {
   myTable.deleteRow(x);
}

I don't believe there's anything built-in for this. It's made tricky by the fact that it's rare for a single line to change several times without the rest of the file changing substantially too, so you'll tend to end up with the line numbers changing a lot.

If you're lucky enough that the line always has some identifying characteristic, e.g. an assignment to a variable whose name never changed, you could use the regex choice for git blame -L. For example:

git blame -L '/variable_name *= */',+1

But this only finds the first match for that regex, so if you don't have a good way of matching the line, it's not too helpful.

You could hack something up, I suppose. I don't have time to write out code just now, but... something along these lines. Run git blame -n -L $n,$n $file. The first field is the previous commit touched, and the second field is the line number in that commit, since it could've changed. Grab those, and run git blame -n $n,$n $commit^ $file, i.e. the same thing starting from the commit before the last time the file was changed.

(Note that this will fail you if the last commit that changed the line was a merge commit. The primary way this could happen if the line was changed as part of a merge conflict resolution.)

Edit: I happened across this mailing list post from March 2011 today, which mentions that tig and git gui have a feature that will help you do this. It looks like the feature has been considered, but not finished, for git itself.

You can just capture the output and pass it through a filter, something like:

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | sort -n -k12

The two greps strip out the header and trailer lines (others may be needed if there are other lines not containing useful information) and the sort is done based on the numeric field number 12 (I think that's right).

This one works for your immediate output:

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | grep -v  '^[0-9][0-9]* rows in set '
    | grep -v '^ '
    | sort -n -k12

ExpressiveAnnotations gives you such a possibility:

[Required]
[AssertThat("Length(FieldA) + Length(FieldB) + Length(FieldC) + Length(FieldD) > 50")]
public string FieldA { get; set; }

The solution for my case is:

1. Right click the output window;
2. Check the 'Program Output'

this works:

if (WindowState == FormWindowState.Minimized)
    WindowState = FormWindowState.Normal;
else
{
    TopMost = true;
    Focus();
    BringToFront();
    TopMost = false;
}

Date Between Query

SELECT *
    FROM emp
    WHERE HIREDATE between to_date (to_char(sysdate, 'yyyy') ||'/09/01', 'yyyy/mm/dd')
    AND to_date (to_char(sysdate, 'yyyy') + 1|| '/08/31', 'yyyy/mm/dd');

Yes. This should work on all major browsers.

document.getElementsByClassName returns an array of elements. so may be you want to target a specific index of them: var comment = document.getElementsByClassName('button')[0]; should get you what you want.

Update #1:

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment() {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

Update #2: (with removeEventListener incorporated as well)

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment(e) {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
  for (var i = 0; i < numComments; i++) {
    comments[i].removeEventListener('click', showComment, false);
  }
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

It actually tells you what's wrong, but you ignored it because you didn't check the error returned from json.Marshal.

json: unsupported type: map[int]main.Foo

JSON spec doesn't support anything except strings for object keys, while javascript won't be fussy about it, it's still illegal.

You have two options:

1 Use map[string]Foo and convert the index to string (using fmt.Sprint for example):

datas := make(map[string]Foo, N)

for i := 0; i < 10; i++ {
    datas[fmt.Sprint(i)] = Foo{Number: 1, Title: "test"}
}
j, err := json.Marshal(datas)
fmt.Println(string(j), err)

2 Simply just use a slice (javascript array):

datas2 := make([]Foo, N)
for i := 0; i < 10; i++ {
    datas2[i] = Foo{Number: 1, Title: "test"}
}
j, err = json.Marshal(datas2)
fmt.Println(string(j), err)

VB6 Installs just fine on Windows 7 (and Windows 8 / Windows 10) with a few caveats.

Here is how to install it:

• Before proceeding with the installation process below, create a zero-byte file in C:\Windows called MSJAVA.DLL. The setup process will look for this file, and if it doesn't find it, will force an installation of old, old Java, and require a reboot. By creating the zero-byte file, the installation of moldy Java is bypassed, and no reboot will be required.
• Turn off UAC.
• Insert Visual Studio 6 CD.
• Exit from the Autorun setup.
• Browse to the root folder of the VS6 CD.
• Right-click SETUP.EXE, select Run As Administrator.
• On this and other Program Compatibility Assistant warnings, click Run Program.
• Click Next.
• Click "I accept agreement", then Next.
• Enter name and company information, click Next.
• Select Custom Setup, click Next.
• Click Continue, then Ok.
• Setup will "think to itself" for about 2 minutes. Processing can be verified by starting Task Manager, and checking the CPU usage of ACMSETUP.EXE.
• On the options list, select the following:
  • Microsoft Visual Basic 6.0
  • ActiveX
  • Data Access
  • Graphics
  • All other options should be unchecked.
• Click Continue, setup will continue.
• Finally, a successful completion dialog will appear, at which click Ok. At this point, Visual Basic 6 is installed.
• If you do not have the MSDN CD, clear the checkbox on the next dialog, and click next. You'll be warned of the lack of MSDN, but just click Yes to accept.
• Click Next to skip the installation of Installshield. This is a really old version you don't want anyway.
• Click Next again to skip the installation of BackOffice, VSS, and SNA Server. Not needed!
• On the next dialog, clear the checkbox for "Register Now", and click Finish.
• The wizard will exit, and you're done. You can find VB6 under Start, All Programs, Microsoft Visual Studio 6. Enjoy!
• Turn On UAC again

• You might notice after successfully installing VB6 on Windows 7 that working in the IDE is a bit, well, sluggish. For example, resizing objects on a form is a real pain.
• After installing VB6, you'll want to change the compatibility settings for the IDE executable.
• Using Windows Explorer, browse the location where you installed VB6. By default, the path is C:\Program Files\Microsoft Visual Studio\VB98\
• Right click the VB6.exe program file, and select properties from the context menu.
• Click on the Compatibility tab.
• Place a check in each of these checkboxes:
• Run this program in compatibility mode for Windows XP (Service Pack 3)
  • Disable Visual Themes
  • Disable Desktop Composition
  • Disable display scaling on high DPI settings
  • If you have UAC turned on, it is probably advisable to check the 'Run this program as an Administrator' box

After changing these settings, fire up the IDE, and things should be back to normal, and the IDE is no longer sluggish.

Unlike many languages, Kotlin distinguishes between mutable and immutable collections (lists, sets, maps, etc). Precise control over exactly when collections can be edited is useful for eliminating bugs, and for designing good APIs.

https://kotlinlang.org/docs/reference/collections.html

You'll need to use a MutableList list.

class TempClass {
    var myList: MutableList<Int> = mutableListOf<Int>()
    fun doSomething() {
        // myList = ArrayList<Int>() // initializer is redundant
        myList.add(10)
        myList.remove(10)
    }
}

MutableList<Int> = arrayListOf() should also work.

right click on a table and click script table as select

You can use my highlight script from https://github.com/kepkin/dev-shell-essentials

It's better than grep because you can highlight each match with its own color.

$ command_here | highlight green "input" | highlight red "output"

I've used the following code a few times and it works sweet:

$("body").click(function(e){ 
    // Check what has been clicked:
    var target = $(e.target); 
    if(target.is("#target")){
    // The target was clicked
    // Do something...
  }
});

1. Undo the local commit. This will just undo the commit and preserves the changes in working copy

git reset --soft HEAD~1

2. Pull the latest changes

git pull

3. Now you can commit your changes on top of latest code

You'll need to learn how to use sed http://unixhelp.ed.ac.uk/CGI/man-cgi?sed

And also to use for so you can loop through your file entries http://www.cyberciti.biz/faq/bash-for-loop/

Your command will look something like this, I don't have a term beside me so I can't check

for i in `dir` do mv $i `echo $i | sed '/orig/new/g'`

you could also store your data in an service with an setter and get it over a getter

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

@Injectable()
export class StorageService {

    public scope: Array<any> | boolean = false;

    constructor() {
    }

    public getScope(): Array<any> | boolean {
        return this.scope;
    }

    public setScope(scope: any): void {
        this.scope = scope;
    }
}

You're only exporting it in your NgModule, you need to import it too

@NgModule({
  imports: [
    MatButtonModule,
    MatFormFieldModule,
    MatInputModule,
    MatRippleModule,
 ]
  exports: [
    MatButtonModule,
    MatFormFieldModule,
    MatInputModule,
    MatRippleModule,
  ],
  declarations: [
    SearchComponent,
  ],
})export class MaterialModule {};

better yet

const modules = [
        MatButtonModule,
        MatFormFieldModule,
        MatInputModule,
        MatRippleModule
];

@NgModule({
  imports: [...modules],
  exports: [...modules]
  ,
})export class MaterialModule {};

update

You're declaring component (SearchComponent) depending on Angular Material before all Angular dependency are imported

Like BrowserAnimationsModule

Try moving it to MaterialModule, or before it

Wrap each individual condition in parentheses, and then use the & operator to combine the conditions:

df.loc[(df['one'] >= df['two']) & (df['one'] <= df['three']), 'que'] = df['one']

You can fill the non-matching rows by just using ~ (the "not" operator) to invert the match:

df.loc[~ ((df['one'] >= df['two']) & (df['one'] <= df['three'])), 'que'] = ''

You need to use & and ~ rather than and and not because the & and ~ operators work element-by-element.

The final result:

df
Out[8]: 
  one  two three que
0  10  1.2   4.2  10
1  15   70  0.03    
2   8    5     0  

Match objects are always true, and None is returned if there is no match. Just test for trueness.

Code:

>>> st = 'bar'
>>> m = re.match(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
...
'bar'

Output = bar

If you want search functionality

>>> st = "bar"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m is not None:
...     m.group(0)
...
'bar'

and if regexp not found than

>>> st = "hello"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
... else:
...   print "no match"
...
no match

As @bukzor mentioned if st = foo bar than match will not work. So, its more appropriate to use re.search.

You want to save it as a file?

import numpy as np

myList = [1, 2, 3]

np.array(myList).dump(open('array.npy', 'wb'))

... and then read:

myArray = np.load(open('array.npy', 'rb'))

I think you want something like this:

Intent foo = new Intent(this, viewContacts.class);
foo.putExtra("myFirstKey", "myFirstValue");
foo.putExtra("mySecondKey", "mySecondValue");
startActivity(foo);

or you can combine them into a bundle first. Corresponding getExtra() routines exist for the other side. See the intent topic in the dev guide for more information.

I can see libc error in the log.

install these packages in your system

sudo apt-get install lib32stdc++6 lib32z1 lib32z1-dev

Restart android studio after installation

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

I need some extra operation based on the result of aggregate function. Finally I've found some solution for aggregate function and the operation based on the result in MongoDB. I've a collection Request with field request, source, status, requestDate.

Single Field Group By & Count:

db.Request.aggregate([
    {"$group" : {_id:"$source", count:{$sum:1}}}
])

Multiple Fields Group By & Count:

db.Request.aggregate([
    {"$group" : {_id:{source:"$source",status:"$status"}, count:{$sum:1}}}
])

Multiple Fields Group By & Count with Sort using Field:

db.Request.aggregate([
    {"$group" : {_id:{source:"$source",status:"$status"}, count:{$sum:1}}},
    {$sort:{"_id.source":1}}
])

Multiple Fields Group By & Count with Sort using Count:

db.Request.aggregate([
    {"$group" : {_id:{source:"$source",status:"$status"}, count:{$sum:1}}},
    {$sort:{"count":-1}}
])

Bootstrap 4

This is what worked for me:

I created my own _custom_theme.scss file with content similar to:

/* To simplify I'm only changing the primary color */
$theme-colors: ( "primary":#ffd800);

Added it to the top of the file bootstrap.scss and recompiled (In my case I had it in a folder called !scss)

@import "../../../!scss/_custom_theme.scss";
@import "functions";
@import "variables";
@import "mixins";

If you like an ugly hacks which you should never do in real worlds systems; you could strip all :hover style rules from document.styleSheets.

Just go through all CSS styles with JavaScript and remove all rules, which contain ":hover" in their selector. I use this method when I need to remove :hover styles from bootstrap 2.

_.each(document.styleSheets, function (sheet) { 
    var rulesToLoose = []; 
    _.each(sheet.cssRules, function (rule, index) { 
        if (rule.selectorText && rule.selectorText.indexOf(':hover') > 0) { 
            rulesToLoose.push(index);
        }
    });

    _.each(rulesToLoose.reverse(), function (index) {
        if (sheet.deleteRule) {
            sheet.deleteRule(index);
        } else if (sheet.removeRule) {
            sheet.removeRule(index);
        }
    });
});

I did use underscore for iterating arrays, but one could write those with pure js loop as well:

for (var i = 0; i < document.styleSheets.length; i++) {}

Here i have written a logic try it :)

public class palindromeClass{

public  static String longestPalindromeString(String in) {
        char[] input = in.toCharArray();
        int longestPalindromeStart = 0;
        int longestPalindromeEnd = 0;

        for (int mid = 0; mid < input.length; mid++) {
            // for odd palindrome case like 14341, 3 will be the mid
            int left = mid-1;
            int right = mid+1;
            // we need to move in the left and right side by 1 place till they reach the end
            while (left >= 0 && right < input.length) {
                // below check to find out if its a palindrome
                if (input[left] == input[right]) {
                    // update global indexes only if this is the longest one till now
                    if (right - left > longestPalindromeEnd
                            - longestPalindromeStart) {
                        longestPalindromeStart = left;
                        longestPalindromeEnd = right;
                    }
                }
                else
                    break;
                left--;
                right++;
            }
            // for even palindrome, we need to have similar logic with mid size 2
            // for that we will start right from one extra place
            left = mid;
            right = mid + 1;// for example 12333321 when we choose 33 as mid
            while (left >= 0 && right < input.length)
            {
                if (input[left] == input[right]) {
                    if (right - left > longestPalindromeEnd
                            - longestPalindromeStart) {
                        longestPalindromeStart = left;
                        longestPalindromeEnd = right;
                    }
                }
                else
                    break;
                left--;
                right++;
            }


        }
        // we have the start and end indexes for longest palindrome now
        return in.substring(longestPalindromeStart, longestPalindromeEnd + 1);
    }
public static void main(String args[]){
System.out.println(longestPalindromeString("HYTBCABADEFGHABCDEDCBAGHTFYW12345678987654321ZWETYGDE"));
}

}

Handle the Worksheet_Change event or the Workbook_SheetChange event.

The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.

num = int(raw_input())
list_num = list(str(num))
if list_num[::-1] == list_num:
    print "Its a palindrome"
else:
    print "Its not a palindrom"

If you are using multiple criteria, and want to count the number of non-blank cells in a particular column, you probably want to look at DCOUNTA.

e.g

  A   B   C   D  E   F   G
1 Dog Cat Cow    Dog Cat
2 x   1          x   1
3 x   2 
4 x   1   nb     Result:
5 x   2   nb     1

Formula in E5: =DCOUNTA(A1:C5,"Cow",E1:F2)

Use forward slashes to specify the UNC Path:

open('//HOST/share/path/to/file')

(if your Python client code is also running under Windows)

For me, I had to use Matchers.any(URI.class)

Mockito.when(restTemplate.exchange(Matchers.any(URI.class), Matchers.any(HttpMethod.class), Matchers.<HttpEntity<?>> any(), Matchers.<Class<Object>> any())).thenReturn(myEntity);

The R-inferno, or the basic R-documentation will explain why using df$* is not the best approach here. From the help page for "[" :

"Indexing by [ is similar to atomic vectors and selects a list of the specified element(s). Both [[ and $ select a single element of the list. The main difference is that $ does not allow computed indices, whereas [[ does. x$name is equivalent to x[["name", exact = FALSE]]. Also, the partial matching behavior of [[ can be controlled using the exact argument. "

I recommend using the [row,col] notation instead. Example:

Rgames: foo   
         x    y z  
   [1,] 1e+00 1 0  
   [2,] 2e+00 2 0  
   [3,] 3e+00 1 0  
   [4,] 4e+00 2 0  
   [5,] 5e+00 1 0  
   [6,] 6e+00 2 0  
   [7,] 7e+00 1 0  
   [8,] 8e+00 2 0  
   [9,] 9e+00 1 0  
   [10,] 1e+01 2 0  
Rgames: foo<-as.data.frame(foo)

Rgames: foo[foo$y==2,3]<-foo[foo$y==2,1]
Rgames: foo
       x y     z
1  1e+00 1 0e+00
2  2e+00 2 2e+00
3  3e+00 1 0e+00
4  4e+00 2 4e+00
5  5e+00 1 0e+00
6  6e+00 2 6e+00
7  7e+00 1 0e+00
8  8e+00 2 8e+00
9  9e+00 1 0e+00
10 1e+01 2 1e+01

You can turn an array into a stream by using Arrays.stream():

int[] ns = new int[] {1,2,3,4,5};
Arrays.stream(ns);

Once you've got your stream, you can use any of the methods described in the documentation, like sum() or whatever. You can map or filter like in Python by calling the relevant stream methods with a Lambda function:

Arrays.stream(ns).map(n -> n * 2);
Arrays.stream(ns).filter(n -> n % 4 == 0);

Once you're done modifying your stream, you then call toArray() to convert it back into an array to use elsewhere:

int[] ns = new int[] {1,2,3,4,5};
int[] ms = Arrays.stream(ns).map(n -> n * 2).filter(n -> n % 4 == 0).toArray();

A slightly more efficient version of the bytes2String method is

private static final char[] hex = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
private static String byteArray2Hex(byte[] bytes) {
    StringBuilder sb = new StringBuilder(bytes.length * 2);
    for (final byte b : bytes) {
        sb.append(hex[(b & 0xF0) >> 4]);
        sb.append(hex[b & 0x0F]);
    }
    return sb.toString();
}

#if DEBUG
bool bypassCheck=TRUE_OR_FALSE;//i will decide depending on what i am debugging
#else
bool bypassCheck = false; //NEVER bypass it
#endif

Make sure you have the checkbox to define DEBUG checked in your build properties.

In addition at the Daniel Vassallo solution, if you use SQL Server 2016+, there is another solution that I used in some cases without considerable lost of performances.

You can create just a table with only the common field and add a single column with the JSON string that contains all the subtype specific fields.

I have tested this design for manage inheritance and I am very happy for the flexibility that I can use in the relative application.

Your code is correct. Kindly mark small correction.

#rightcolumn {
     width: 750px;
     background-color: #777;
     display: block;
     **float: left;(wrong)**
     **float: right; (corrected)**
     border: 1px solid white;
}

Using Visual Studio

1. Attach a debugger to the process (e.g. start with debugging or Debug > Attach to process)
2. While debugging, show the Modules window (Debug > Windows > Modules)

This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).

Using Process Explorer

If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)

Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.

Programmatically

Check this SO question that explains how to do it.

If you have hashes '#' in your URL, all the solutions here do not work. This is the only solution that worked for me.

var hrefa = window.location.href.split("#")[1];
var hrefb = window.location.href.split("#")[2];
window.location.href  = window.location.pathname +  window.location.search + '&x=x#' + hrefa + '#' + hrefb;

The URL has to be different for it to reload if you have a hash. The &x=x does that here. Just substitute this for something you can ignore. THis is abit of a hack, unable to find a better solution..

Tested in Firefox.

You still need to use their proprietary filters as of IE9 beta 1.

DSM has the accepted answer, but the coding doesn't seem to work for everyone. Here is one that works with the current version of pandas (0.23.4 as of 8/2018):

import pandas as pd

df = pd.DataFrame({'col1': [1, 2, 2, 3, 1],
            'col2': ['negative', 'positive', 'neutral', 'neutral', 'positive']})

conversion_dict = {'negative': -1, 'neutral': 0, 'positive': 1}
df['converted_column'] = df['col2'].replace(conversion_dict)

print(df.head())

You'll see it looks like:

   col1      col2  converted_column
0     1  negative                -1
1     2  positive                 1
2     2   neutral                 0
3     3   neutral                 0
4     1  positive                 1

The docs for pandas.DataFrame.replace are here.

In C the char type has a numeric value so the > operator will work just fine for example

#include <stdio.h>
main() {

    char a='z';

    char b='h';

    if ( a > b ) {
        printf("%c greater than %c\n",a,b);
    }
}

Just override the onKeyDown method and check if the back button was pressed.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) 
{
    if (keyCode == KeyEvent.KEYCODE_BACK) 
    {
        //Back buttons was pressed, do whatever logic you want
    }

    return false;
}

Spring is a good alternative to Enterprise JavaBeans (EJB) technology. It also has web framework and web services framework component.

I am using lambda with Zappa; I am sending data with POST in json format:

My code for basic_lambda_pure.py is:

import time
import requests
import json
def my_handler(event, context):
    print("Received event: " + json.dumps(event, indent=2))
    print("Log stream name:", context.log_stream_name)
    print("Log group name:",  context.log_group_name)
    print("Request ID:", context.aws_request_id)
    print("Mem. limits(MB):", context.memory_limit_in_mb)
    # Code will execute quickly, so we add a 1 second intentional delay so you can see that in time remaining value.
    print("Time remaining (MS):", context.get_remaining_time_in_millis())

    if event["httpMethod"] == "GET":
        hub_mode = event["queryStringParameters"]["hub.mode"]
        hub_challenge = event["queryStringParameters"]["hub.challenge"]
        hub_verify_token = event["queryStringParameters"]["hub.verify_token"]
        return {'statusCode': '200', 'body': hub_challenge, 'headers': 'Content-Type': 'application/json'}}

    if event["httpMethod"] == "post":
        token = "xxxx"
    params = {

        _data = {"recipient": {"id": 1459299024159359}}
        _data.update({"message": {"text": "text"}})
        data = json.dumps(_data)
        r = requests.post("https://graph.facebook.com/v2.9/me/messages",params=params, headers=headers, data=data, timeout=2)
        return {'statusCode': '200', 'body': "ok", 'headers': {'Content-Type': 'application/json'}}

Demo: http://www.stoimen.com/jquery.client.plugin/

This is based on quirksmode BrowserDetect a wrap for jQuery browser/os detection plugin.

For keen readers:
http://www.stoimen.com/blog/2009/07/16/jquery-browser-and-os-detection-plugin/
http://www.quirksmode.org/js/support.html

And more code around the plugin resides here: http://www.stoimen.com/jquery.client.plugin/jquery.client.js

Also one can use this:

{% if forloop.first %}

or

{% if forloop.last %}

First of all you need to be sure that all attributes of that comes from the service are named the same in your class. Then you can parse the object and after that assign it to your new variable, something like this:

const parsedJSON = JSON.parse(serverResponse);
const employeeObj: Employee = parsedJSON as Employee;

Try that!

This will work:

>>> t = [1,1,2,2,3,3,4,5]
>>> print list(set(t))
[1,2,3,4,5]

However, if you have used "list" or "set" as a variable name you will get the:

TypeError: 'set' object is not callable

eg:

>>> set = [1,1,2,2,3,3,4,5]
>>> print list(set(set))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable

Same error will occur if you have used "list" as a variable name.

I was really looking for a way to fetch the connection status of a device, not listen to connection events. Here's what worked for me:

BluetoothManager bm = (BluetoothManager) context.getSystemService(Context.BLUETOOTH_SERVICE);
List<BluetoothDevice> devices = bm.getConnectedDevices(BluetoothGatt.GATT);
int status = -1;

for (BluetoothDevice device : devices) {
  status = bm.getConnectionState(device, BLuetoothGatt.GATT);
  // compare status to:
  //   BluetoothProfile.STATE_CONNECTED
  //   BluetoothProfile.STATE_CONNECTING
  //   BluetoothProfile.STATE_DISCONNECTED
  //   BluetoothProfile.STATE_DISCONNECTING
}

You can use IEnumerable to eliminate the need of a temp list.

public IEnumerable<T> GetFilteredItems(IEnumerable<T> collection)
{
    foreach (T item in collection)
    if (Matches<T>(item))
    {
        yield return item;
    }
}

where Matches is the name of your filter method. And you can use this like:

IEnumerable<MyType> filteredItems = GetFilteredItems(myList);
foreach (MyType item in filteredItems)
{
    // do sth with your filtered items
}

This will call GetFilteredItems function when needed and in some cases that you do not use all items in the filtered collection, it may provide some good performance gain.

Hints:

import string
print string.ascii_lowercase

and

for i in xrange(0, 10, 2):
    print i

and

"hello{0}, world!".format('z')

Here's Microsoft's write up on using SET IDENTITY_INSERT, which might be helpful to others seeing this post if they, like me, found this post when trying to recreate deleted records while maintaining the original identity column value.

to recreate deleted records with original identity column value: http://msdn.microsoft.com/en-us/library/aa259221(v=sql.80).aspx

You just need to change the chartObject.data.datasets value and call update() like this:

chartObject.data.datasets = newData.datasets;
chartObject.data.labels = newData.labels;
chartObject.update();

Did you remember setting the height of the html and body tags in your CSS? This is generally how I've gotten DIVs to extend to full height:

<html>
  <head>
    <style type="text/css">

      html,body { height: 100%; margin: 0px; padding: 0px; }
      #full { background: #0f0; height: 100% }

    </style>
  </head>
  <body>
    <div id="full">
    </div>
  </body>
</html>

Well, technically any such object will wind up being built over a C-style thread library because C++ only just specified a stock std::thread model in c++0x, which was just nailed down and hasn't yet been implemented. The problem is somewhat systemic, technically the existing c++ memory model isn't strict enough to allow for well defined semantics for all of the 'happens before' cases. Hans Boehm wrote an paper on the topic a while back and was instrumental in hammering out the c++0x standard on the topic.

http://www.hpl.hp.com/techreports/2004/HPL-2004-209.html

That said there are several cross-platform thread C++ libraries that work just fine in practice. Intel thread building blocks contains a tbb::thread object that closely approximates the c++0x standard and Boost has a boost::thread library that does the same.

http://www.threadingbuildingblocks.org/

http://www.boost.org/doc/libs/1_37_0/doc/html/thread.html

Using boost::thread you'd get something like:

#include <boost/thread.hpp>

void task1() { 
    // do stuff
}

void task2() { 
    // do stuff
}

int main (int argc, char ** argv) {
    using namespace boost; 
    thread thread_1 = thread(task1);
    thread thread_2 = thread(task2);

    // do other stuff
    thread_2.join();
    thread_1.join();
    return 0;
}

Here is an example of concatenation operator:

architecture EXAMPLE of CONCATENATION is
   signal Z_BUS : bit_vector (3 downto 0);
   signal A_BIT, B_BIT, C_BIT, D_BIT : bit;
begin
   Z_BUS <= A_BIT & B_BIT & C_BIT & D_BIT;
end EXAMPLE;

I needed a more flexible solution for working on multiple git repositories so I wrote the following sh code based on 1 and 2. You can use your server address instead of gitlab.com and your port in replace of 22.

SERVER=gitlab.com
PORT=22
nc -z -v -w5 $SERVER $PORT
result1=$?

#Do whatever you want

if [  "$result1" != 0 ]; then
  echo  'port 22 is closed'
else
  echo 'port 22 is open'
fi

This --> is not an operator at all. We have an operator like ->, but not like -->. It is just a wrong interpretation of while(x-- >0) which simply means x has the post decrement operator and this loop will run till it is greater than zero.

Another simple way of writing this code would be while(x--). The while loop will stop whenever it gets a false condition and here there is only one case, i.e., 0. So it will stop when the x value is decremented to zero.

Express version:

"dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1"
  }

Optional parameter are very much handy, you can declare and use them easily using express:

app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
    console.log("category Id: "+req.params.cId);
    console.log("product ID: "+req.params.pId);
    if (req.params.batchNo){
        console.log("Batch No: "+req.params.batchNo);
    }
});

In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'

Now I can call with only categoryId and productId or with all three-parameter.

http://127.0.0.1:3000/api/v1/tours/5/10
//or
http://127.0.0.1:3000/api/v1/tours/5/10/8987

I've historically rolled my own access at a low level (XML generation and parsing) to deal with the occasional need to do SOAP style requests from Objective-C. That said, there's a library available called SOAPClient (soapclient) that is open source (BSD licensed) and available on Google Code (mac-soapclient) that might be of interest.

I won't attest to it's abilities or effectiveness, as I've never used it or had to work with it's API's, but it is available and might provide a quick solution for you depending on your needs.

Apple had, at one time, a very broken utility called WS-MakeStubs. I don't think it's available on the iPhone, but you might also be interested in an open-source library intended to replace that - code generate out Objective-C for interacting with a SOAP client. Again, I haven't used it - but I've marked it down in my notes: wsdl2objc

I think you have put command like java -VERSION. This is in capital letters You need to put all command in lowercase letters

javac -version
java -version

All characters must be in lowercase letter

Put it inside your <footer> by all means, but the most fitting element is the small element.

The HTML5 spec for this says:

Small print typically features disclaimers, caveats, legal restrictions, or copyrights. Small print is also sometimes used for attribution, or for satisfying licensing requirements.

I had a similar issue and it was because I was missing a closing > on a style sheet link.

In java, we can do as follows :

AWSLambdaAsync awsLambdaAsync = AWSLambdaAsyncClientBuilder.standard().withRegion("us-east-1").build();

InvokeRequest invokeRequest = new InvokeRequest();
invokeRequest.withFunctionName("youLambdaFunctionNameToCall").withPayload(payload);

InvokeResult invokeResult = awsLambdaAsync.invoke(invokeRequest); 

Here, payload is your stringified java object which needs to be passed as Json object to another lambda in case you need to pass some information from calling lambda to called lambda.

h_url=document.getElementById("u") is null here

There is no element exist with id as u

I tried a number of the solutions above however the fix in our scenario was to install the fpm-module.

We had installed httpd before php which may have had something to do with the issue, but to resolve we installed the following:

yum module install php:7.2

This installed the php-fpm-7.2.11-4.module+el8.1.0+5443+bc1aeb77.x86_64.rpm module which we then enabled by:

systemctl enable --now php-fpm

From that point we left the /etc/httpd/conf.d/php.conf as default and restarted httpd

service httpd restart

Then everything worked.

Hope this helps, took way longer than it should have to figure out.

Just tested:

Run the following command:

sudo shred -u /etc/ssh/*_key /etc/ssh/*_key.pub

Then:

1. create ami (image of the ec2).
2. launch from new ami(image) from step no 2 chose new keys.

You can use $expr ( 3.6 mongo version operator ) to use aggregation functions in regular query.

Compare query operators vs aggregation comparison operators.

Regular Query:

db.T.find({$expr:{$gt:["$Grade1", "$Grade2"]}})

Aggregation Query:

db.T.aggregate({$match:{$expr:{$gt:["$Grade1", "$Grade2"]}}})

You may also want not to spawn StringBuilder for such simple operation. Please note that I've changed name of your array from name to names for sake of content conformity:

String[] names = {"amit", "rahul", "surya"};

String namesString = "";
int delimeters = (names.size() - 1);
for (String name : names)
    namesString += (delimeters-- > 0) ? "'" + name + "'," : "'" + name + "'";

I had the same problem (readyState was 4 and status 0), then I followed a different approach explained in this tutorial: https://spring.io/guides/gs/consuming-rest-jquery/

He didn't use XMLHttpRequest at all, instead he used jquery $.ajax() method:

<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script src="hello.js"></script>
</head>

<body>
    <div>
        <p class="greeting-id">The ID is </p>
        <p class="greeting-content">The content is </p>
    </div>
</body>

and for the public/hello.js file (or you could insert it in the same HTML code directly):

$(document).ready(function() 
 {
    $.ajax({
        url: "http://rest-service.guides.spring.io/greeting"
   }).then(function(data) {
      $('.greeting-id').append(data.id);
      $('.greeting-content').append(data.content);
   });
 });

The hash solution is nice but not really human readable when you want to know what version of file is sitting in your local web folder. The solution is to date/time stamp your version so you can easily compare it against your server file.

For example, if your .js or .css file is dated 2011-02-08 15:55:30 (last modification) then the version should equal to .js?v=20110208155530

Should be easy to read properties of any file in any language. In ASP.Net it's really easy...

".js?v=" + File.GetLastWriteTime(HttpContext.Current.Request.PhysicalApplicationPath + filename).ToString("yyMMddHHHmmss");

Of coz get it nicely refactored into properties/functions first and off you go. No more excuses.

Good luck, Art.

Had a similar problem on Centos 7. When I tried to apply the solution prescribed by Sorin, I started moving in cycles. First I had a permission {write} denied. Then when I solved that I had a permission { connectto } denied. Then back again to permission {write } denied.

Following @Sid answer above of checking the flags using getsebool -a | grep httpd and toggling them I found that in addition to the httpd_can_network_connect being off. http_anon_write was also off resulting in permission denied write and permission denied {connectto}

type=AVC msg=audit(1501830505.174:799183): avc:  
denied  { write } for  pid=12144 comm="nginx" name="myroject.sock" 
dev="dm-2" ino=134718735 scontext=system_u:system_r:httpd_t:s0 
tcontext=system_u:object_r:default_t:s0 tclass=sock_file

Obtained using sudo cat /var/log/audit/audit.log | grep nginx | grep denied as explained above.

So I solved them one at a time, toggling the flags on one at a time.

setsebool httpd_can_network_connect on -P

Then running the commands specified by @sorin and @Joseph above

sudo cat /var/log/audit/audit.log | grep nginx | grep denied | 
audit2allow -M mynginx
sudo semodule -i mynginx.pp

Basically you can check the permissions set on setsebool and correlate that with the error obtained from grepp'ing' audit.log nginx, denied

You seem to be misunderstanding how import searches for modules. When you use an import statement it always searches the actual module path (and/or sys.modules); it doesn't make use of module objects in the local namespace that exist because of previous imports. When you do:

import package.subpackage.module
from package.subpackage import module
from module import attribute1

The second line looks for a package called package.subpackage and imports module from that package. This line has no effect on the third line. The third line just looks for a module called module and doesn't find one. It doesn't "re-use" the object called module that you got from the line above.

In other words from someModule import ... doesn't mean "from the module called someModule that I imported earlier..." it means "from the module named someModule that you find on sys.path...". There is no way to "incrementally" build up a module's path by importing the packages that lead to it. You always have to refer to the entire module name when importing.

It's not clear what you're trying to achieve. If you only want to import the particular object attribute1, just do from package.subpackage.module import attribute1 and be done with it. You need never worry about the long package.subpackage.module once you've imported the name you want from it.

If you do want to have access to the module to access other names later, then you can do from package.subpackage import module and, as you've seen you can then do module.attribute1 and so on as much as you like.

If you want both --- that is, if you want attribute1 directly accessible and you want module accessible, just do both of the above:

from package.subpackage import module
from package.subpackage.module import attribute1
attribute1 # works
module.someOtherAttribute # also works

If you don't like typing package.subpackage even twice, you can just manually create a local reference to attribute1:

from package.subpackage import module
attribute1 = module.attribute1
attribute1 # works
module.someOtherAttribute #also works

@user264892

I found that when using a String variable I needed to either prefix with an String of "" or explicitly cast to CharSequence.

So instead of:

String Status = "Asking Server...";
txtStatus.setText(Status);

try:

String Status = "Asking Server...";
txtStatus.setText((CharSequence) Status);

or:

String Status = "Asking Server...";    
txtStatus.setText("" + Status);

or, since your string is not dynamic, even better:

txtStatus.setText("AskingServer...");

You can use jQuery's Deferred object along with the when method.

deferredArray = [];
forloop {
    deferred = new $.Deferred();
    ajaxCall(function() {
      deferred.resolve();
    }
    deferredArray.push(deferred);
}

$.when(deferredArray, function() {
  //this code is called after all the ajax calls are done
});

3. is the correct answer. WhatsApp is intentionally a closed system without an API for external access.

There were several projects available that reverse engineered the WhatsApp webservice interfaces. However, to my knowledge all of them are now discontinued/defunct due to legal action against them from WhatsApp.

For mobile phone applications there is a limited URL-Scheme-API available on IPhone and Android (Android-intent possible as well).

I came to this post when i was searching for the same issue but in android. I don't say this is the best way to get sorted files by last modified date, but its the easiest way I found yet.

Below code may be helpful to someone-

File downloadDir = new File("mypath");    
File[] list = downloadDir.listFiles();
    for (int i = list.length-1; i >=0 ; i--) {
        //use list.getName to get the name of the file
    }

Thanks

Quick Answer:

git stash pop -> remove from the stash list

git stash apply -> keep it in the stash list

Android Studio 3.0

I love how easy this is in Android Studio.

1. Enter your GitHub login info

In Android Studio go to File > Settings > Version Control > GitHub. Then enter your GitHub username and password. (You only have to do this step once. For future projects you can skip it.)

2. Share your project

With your Android Studio project open, go to VCS > Import into Version Control > Share Project on GitHub.

Then click Share and OK.

That's all!

Using a normal css selector:

$('.sys input[type=text], .sys select').each(function() {...})

If you don't like the repetition:

$('.sys').find('input[type=text],select').each(function() {...})

Or more concisely, pass in the context argument:

$('input[type=text],select', '.sys').each(function() {...})

Note: Internally jQuery will convert the above to find() equivalent

http://api.jquery.com/jQuery/

Internally, selector context is implemented with the .find() method, so $('span', this) is equivalent to $(this).find('span').

I personally find the first alternative to be the most readable :), your take though

Additionally, DataContractSerializer will serialize items marked as [Serializable] and will also serialize unmarked types in .NET 3.5 SP1 and later, to allow support for serializing anonymous types.

So, it depends on how you've decorated your class as to how to keep a member from serializing:

• If you used [DataContract], then remove the [DataMember] for the property.
• If you used [Serializable], then add [NonSerialized] in front of the field for the property.
• If you haven't decorated your class, then you should add [IgnoreDataMember] to the property.

git grep

Here is the syntax using git grep combining multiple patterns using Boolean expressions:

git grep -e pattern1 --and -e pattern2 --and -e pattern3

^{The above command will print lines matching all the patterns at once.}

If the files aren't under version control, add --no-index param.

Search files in the current directory that is not managed by Git.

Check man git-grep for help.

• Check if all of multiple strings or regexes exist in a file.

Unfortunately, all suggestions except from B-Money are invalid for most cases.

Here is a lot of valid emails like:

• gü[email protected] (German umlaut)
• ?????@??????.?? (Russian, ?? is a valid domain)
• chinese and many other languages (see for example International email and linked specs).

Because of complexity to get validation right, I propose a very generic solution:

<input type="text" pattern="[^@\s]+@[^@\s]+\.[^@\s]+" title="Invalid email address" />

It checks if email contains at least one character (also number or whatever except another "@" or whitespace) before "@", at least two characters (or whatever except another "@" or whitespace) after "@" and one dot in between. This pattern does not accept addresses like lol@company, sometimes used in internal networks. But this one could be used, if required:

<input type="text" pattern="[^@\s]+@[^@\s]+" title="Invalid email address" />

Both patterns accepts also less valid emails, for example emails with vertical tab. But for me it's good enough. Stronger checks like trying to connect to mail-server or ping domain should happen anyway on the server side.

BTW, I just wrote angular directive (not well tested yet) for email validation with novalidate and without based on pattern above to support DRY-principle:

.directive('isEmail', ['$compile', '$q', 't', function($compile, $q, t) {
    var EMAIL_PATTERN = '^[^@\\s]+@[^@\\s]+\\.[^@\\s]+$';
    var EMAIL_REGEXP = new RegExp(EMAIL_PATTERN, 'i');
    return {
        require: 'ngModel',
        link: function(scope, elem, attrs, ngModel){
            function validate(value) {
                var valid = angular.isUndefined(value)
                    || value.length === 0
                    || EMAIL_REGEXP.test(value);
                ngModel.$setValidity('email', valid);
                return valid ? value : undefined;
            }
            ngModel.$formatters.unshift(validate);
            ngModel.$parsers.unshift(validate);
            elem.attr('pattern', EMAIL_PATTERN);
            elem.attr('title', 'Invalid email address');
        }
    };
}])

Usage:

<input type="text" is-email />

For B-Money's pattern is "@" just enough. But it decline two or more "@" and all spaces.

<% %>

In SP2013 Online, I tried the filter conditions as Name Contains Folder_I_want_to_list

This showed me all the folders containing the Name in their file path. It lists even sub-folder contents which wasn't available when i tried Name equal to Folder_I_want_to_list

No, you cannot set them all in a single statement.
At the general case, you need at least three properties:

border-color: red green white blue;
border-style: solid dashed dotted solid;
border-width: 1px 2px 3px 4px;

However, that would be quite messy. It would be more readable and maintainable with four:

border-top:    1px solid  #ff0;
border-right:  2px dashed #f0F;
border-bottom: 3px dotted #f00;
border-left:   5px solid  #09f;

You can also go to Notepad++ and do the following steps:

Edit->LineOperations-> Remove Empty Lines or Remove Empty Lines(Containing blank characters)

Yes, it works for me on localhost:

props.put("mail.smtp.ssl.trust", "smtp.gmail.com");

The error is only thrown on localhost, so you should try on remote servers too. Usually, it is the snippet of code mentioned above that works well without ssl.trust property

As this answer says, you can also just wrap your code in an anonymous function like this:

expect(function(){
    model.get('z');
}).to.throw('Property does not exist in model schema.');

• tput cols tells you the number of columns.
• tput lines tells you the number of rows.

What you need is properly a service:

.factory('DataLayer', ['$http',

    function($http) {

        var factory = {};
        var locations;

        factory.getLocations = function(success) {
            if(locations){
                success(locations);
                return;
            }
            $http.get('locations/locations.json').success(function(data) {
                locations = data;
                success(locations);
            });
        };

        return factory;
    }
]);

The locations would be cached in the service which worked as singleton model. This is the right way to fetch data.

Use this service DataLayer in your controller and directive is ok as following:

appControllers.controller('dummyCtrl', function ($scope, DataLayer) {
    DataLayer.getLocations(function(data){
        $scope.locations = data;
    });
});

.directive('map', function(DataLayer) {
    return {
        restrict: 'E',
        replace: true,
        template: '<div></div>',
        link: function(scope, element, attrs) {

            DataLayer.getLocations(function(data) {
                angular.forEach(data, function(location, key){
                    //do something
                });
            });
        }
    };
});

It's not possible to embed videos directly, but you can put an image which links to a YouTube video:

If anyone needs to do this outside the context of the Visual Studio application - via command-line for example, I wrote a small tool which will strip the source control bindings from Solution And Project files. The source is available here: https://github.com/saveenr/VS_unbind_source_control

HTML doesn't recognize the & but it will recognize & because it is equal to & in HTML

I looked over this post someone had made: http://www.webmasterworld.com/forum21/8851.htm

Try this:

if(myString != "-1")

The opperand is != and not =!

You can also use Equals

if(!myString.Equals("-1"))

Note the ! before myString

In case of Oracle since 12c you have DEFAULT ON NULL which implies a NOT NULL constraint.

ALTER TABLE tbl ADD (col VARCHAR(20) DEFAULT ON NULL 'MyDefault');

ALTER TABLE

ON NULL

If you specify the ON NULL clause, then Oracle Database assigns the DEFAULT column value when a subsequent INSERT statement attempts to assign a value that evaluates to NULL.

When you specify ON NULL, the NOT NULL constraint and NOT DEFERRABLE constraint state are implicitly specified. If you specify an inline constraint that conflicts with NOT NULL and NOT DEFERRABLE, then an error is raised.

Add the following line at the top of the file that gives the error:

declare var require: any

Since Ubuntu 16.04 includes snapd by default.
So, the easiest way to install the stable version is

• IntelliJ IDEA Community:
  $ sudo snap install intellij-idea-community --classic
• IntelliJ IDEA Ultimate:
  $ sudo snap install intellij-idea-ultimate --classic

For the latest version use channel --edge
$ sudo snap install intellij-idea-community --classic --edge

Here is the list of all channels https://snapcraft.io/intellij-idea-ultimate (drop down 'All versions').

options

--classic

The --classic option is required because the IntelliJ IDEA snap requires full access to the system, like a traditionally packaged application.
[https://www.jetbrains.com/help/idea/install-and-set-up-product.html#install-on-linux-with-snaps]

--edge

--edge Install from the edge channel [http://manpages.ubuntu.com/manpages/bionic/man1/snap.1.html]

Note: Snap, also work a few major distributions: Arch, Debian, Fedora, openSUSE, Linux Mint,...

This is a well-known nuisance when posting multiline commands in R. (You can get different behavior when you source() a script to when you copy-and-paste the lines, both with multiline and comments)

Rule: always put the dangling '+' at the end of a line so R knows the command is unfinished:

ggplot(...) + geom_whatever1(...) +
  geom_whatever2(...) +
  stat_whatever3(...) +
  geom_title(...) + scale_y_log10(...)

Don't put the dangling '+' at the start of the line, since that tickles the error:

Error in "+ geom_whatever2(...) invalid argument to unary operator"

And obviously don't put dangling '+' at both end and start since that's a syntax error.

So, learn a habit of being consistent: always put '+' at end-of-line.

cf. answer to "Split code over multiple lines in an R script"

For what it is worth, mine was fixed after I went to target->Build Phases->Link Binary With Libraries, deleted the libstdc++.tbd reference, then added a reference to libstdc++.6.0.9.tbd.

MySQL provides a very cute solution :

REPLACE INTO `table` VALUES (5, 'John', 'Doe', SHA1('password'));

Very easy to use since you have declared a unique primary key (here with value 5).

Your best chance is to just perform a simple query against one table, e.g.:

select 1 from SOME_TABLE;

Oh, I just saw there is a new method available since 1.6:

java.sql.Connection.isValid(int timeoutSeconds):

Returns true if the connection has not been closed and is still valid. The driver shall submit a query on the connection or use some other mechanism that positively verifies the connection is still valid when this method is called. The query submitted by the driver to validate the connection shall be executed in the context of the current transaction.

No, this is not possible. In documents that make use of CSS, an inline style attribute can only contain property declarations; the same set of statements that appears in each ruleset in a stylesheet. From the Style Attributes spec:

The value of the style attribute must match the syntax of the contents of a CSS declaration block (excluding the delimiting braces), whose formal grammar is given below in the terms and conventions of the CSS core grammar:

declaration-list
  : S* declaration? [ ';' S* declaration? ]*
  ;

Neither selectors (including pseudo-elements), nor at-rules, nor any other CSS construct are allowed.

Think of inline styles as the styles applied to some anonymous super-specific ID selector: those styles only apply to that one very element with the style attribute. (They take precedence over an ID selector in a stylesheet too, if that element has that ID.) Technically it doesn't work like that; this is just to help you understand why the attribute doesn't support pseudo-class or pseudo-element styles (it has more to do with how pseudo-classes and pseudo-elements provide abstractions of the document tree that can't be expressed in the document language).

Note that inline styles participate in the same cascade as selectors in rule sets, and take highest precedence in the cascade (!important notwithstanding). So they take precedence even over pseudo-class states. Allowing pseudo-classes or any other selectors in inline styles would possibly introduce a new cascade level, and with it a new set of complications.

Note also that very old revisions of the Style Attributes spec did originally propose allowing this, however it was scrapped, presumably for the reason given above, or because implementing it was not a viable option.

Switch the order of the code: You're calling the click event before it is attached.

$(document).ready(function() {
      $("#checkbox_div input:radio").click(function() {

           alert("clicked");

      });

      $("input:radio:first").prop("checked", true).trigger("click");

});

Just brew remove php and brew install php did not work, nor did brew reinstall php. My solution was to do:

brew remove php
cd /usr/local/Cellar
rm -rf php/
brew install php
brew doctor
brew cleanup

Now php -v gives me:

PHP 7.3.2 (cli) (built: Feb 14 2019 10:08:45) ( NTS )

I had the same problem. The problem with the Sublime Text's default console is that it does not support input.

To solve it, you have to install a package called SublimeREPL. SublimeREPL provides a Python interpreter which accepts input.

There is an article that explains the solution in detail.
