Maybe there's still something that can be added, a small example with Django rest_framework, and decorators. This provides an answer to the implicit question: "why would I want this anyway?"

As said: we're with Django rest_framework, and we're using generic views, and for each type of objects in our database we find ourselves with one view class providing GET and POST for lists of objects, and an other view class providing GET, PUT, and DELETE for individual objects.

Now the POST, PUT, and DELETE we want to decorate with Django's login_required. Notice how this touches both classes, but not all methods in either class.

A solution could go through multiple inheritance.

from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import login_required

class LoginToPost:
    @method_decorator(login_required)
    def post(self, arg, *args, **kwargs):
        super().post(arg, *args, **kwargs)

Likewise for the other methods.

In the inheritance list of my concrete classes, I would add my LoginToPost before ListCreateAPIView and LoginToPutOrDelete before RetrieveUpdateDestroyAPIView. My concrete classes' get would stay undecorated.

We all seem to be heading down the interface path with this, but the obvious other possibility, here, is to do what OOP is supposed to do, and build up your inheritance tree... (isn't this what class design is all about?)

class Program
{
    static void Main(string[] args)
    {
        human me = new human();
        me.legs = 2;
        me.lfType = "Human";
        me.name = "Paul";
        Console.WriteLine(me.name);
    }
}

public abstract class lifeform
{
    public string lfType { get; set; }
}

public abstract class mammal : lifeform 
{
    public int legs { get; set; }
}

public class human : mammal
{
    public string name { get; set; }
}

This structure provides reusable blocks of code and, surely, is how OOP code should be written?

If this particular approach doesn't quite fit the bill the we simply create new classes based on the required objects...

class Program
{
    static void Main(string[] args)
    {
        fish shark = new fish();
        shark.size = "large";
        shark.lfType = "Fish";
        shark.name = "Jaws";
        Console.WriteLine(shark.name);
        human me = new human();
        me.legs = 2;
        me.lfType = "Human";
        me.name = "Paul";
        Console.WriteLine(me.name);
    }
}

public abstract class lifeform
{
    public string lfType { get; set; }
}

public abstract class mammal : lifeform 
{
    public int legs { get; set; }
}

public class human : mammal
{
    public string name { get; set; }
}

public class aquatic : lifeform
{
    public string size { get; set; }
}

public class fish : aquatic
{
    public string name { get; set; }
}

you can have an interface hierarchy and then extend your classes from selected interfaces :

public interface IAnimal {
}

public interface IBird implements IAnimal {
}

public  interface IHorse implements IAnimal {
}

public interface IPegasus implements IBird,IHorse{
}

and then define your classes as needed, by extending a specific interface :

public class Bird implements IBird {
}

public class Horse implements IHorse{
}

public class Pegasus implements IPegasus {
}

Java 1.8 (as well as Groovy and Scala) has a thing called "Interface Defender Methods", which are interfaces with pre-defined default method bodies. By implementing multiple interfaces that use defender methods, you could effectively, in a way, extend the behavior of two interface objects.

Also, in Groovy, using the @Delegate annotation, you can extend behavior of two or more classes (with caveats when those classes contain methods of the same name). This code proves it:

class Photo {
    int width
    int height
}    
class Selection {
    @Delegate Photo photo    
    String title
    String caption
}    
def photo = new Photo(width: 640, height: 480)
def selection = new Selection(title: "Groovy", caption: "Groovy", photo: photo)
assert selection.title == "Groovy"
assert selection.caption == "Groovy"    
assert selection.width == 640
assert selection.height == 480

Anonymous classes always extend superclass or implements interfaces. for example:

button.addActionListener(new ActionListener(){ // ActionListener is an interface
    public void actionPerformed(ActionEvent e){
    }
});

Moreover, although anonymous class cannot implement multiple interfaces, you can create an interface that extends other interface and let your anonymous class to implement it.

There is no concept of multiple inheritance in Java. Only multiple interfaces can be implemented.

I'd advise against mix-ins in new Python code, if you can find any other way around it (such as composition-instead-of-inheritance, or just monkey-patching methods into your own classes) that isn't much more effort.

In old-style classes you could use mix-ins as a way of grabbing a few methods from another class. But in the new-style world everything, even the mix-in, inherits from object. That means that any use of multiple inheritance naturally introduces MRO issues.

There are ways to make multiple-inheritance MRO work in Python, most notably the super() function, but it means you have to do your whole class hierarchy using super(), and it's considerably more difficult to understand the flow of control.

An interface can extend other interfaces. Also an interface cannot implement any other interface. When it comes to a class, it can extend one other class and implement any number of interfaces.

class A extends B implements C,D{...}

Yes, you can do it. An interface can extend multiple interfaces, as shown here:

interface Maininterface extends inter1, inter2, inter3 {  
  // methods
}

A single class can also implement multiple interfaces. What if two interfaces have a method defining the same name and signature?

There is a tricky point:

interface A {
    void test();
}

interface B {
    void test();
}

class C implements A, B {

    @Override
    public void test() {

    }     

}

Then single implementation works for both :).

Read my complete post here:

http://codeinventions.blogspot.com/2014/07/can-interface-extend-multiple.html

Sorry, you cannot inherit from multiple classes. You may use interfaces or a combination of one class and interface(s), where interface(s) should follow the class name in the signature.

interface A { }
interface B { }
class Base { }
class AnotherClass { }

Possible ways to inherit:

class SomeClass : A, B { } // from multiple Interface(s)
class SomeClass : Base, B { } // from one Class and Interface(s)

This is not legal:

class SomeClass : Base, AnotherClass { }

Consider the following code:

class X():
    def __init__(self):
        print("X")

class Y(X):
    def __init__(self):
        # X.__init__(self)
        super(Y, self).__init__()
        print("Y")

class P(X):
    def __init__(self):
        super(P, self).__init__()
        print("P")

class Q(Y, P):
    def __init__(self):
        super(Q, self).__init__()
        print("Q")

Q()

If change constructor of Y to X.__init__, you will get:

X
Y
Q

But using super(Y, self).__init__(), you will get:

X
P
Y
Q

And P or Q may even be involved from another file which you don't know when you writing X and Y. So, basically, you won't know what super(Child, self) will reference to when you are writing class Y(X), even the signature of Y is as simple as Y(X). That's why super could be a better choice.

Suppose you are looking for last row of table dbstr.TABNAME, into an INTEGER column named "_ID" (for example BaseColumns._ID), but could be anyother column you want.

public int getLastId() {
    int _id = 0;
    SQLiteDatabase db = dbHelper.getReadableDatabase();
    Cursor cursor = db.query(dbstr.TABNAME, new String[] {BaseColumns._ID}, null, null, null, null, null);

    if (cursor.moveToLast()) {
        _id = cursor.getInt(0);
    }

    cursor.close();
    db.close();
    return _id;
}

What you need is :

1) have a table body of limited height as scroll occurs only when contents is bigger than the scrolling window. However tbody cannot be sized, and you have to display it as a block to do so:

tbody {
   overflow-y: auto;
   display: block;
   max-height: 10em;    // For example
}

2) Re-sync table header and table body columns widths as making the latter a block made it an unrelated element. The only way to do so is to simulate synchronization by enforcing the same columns width to both.

However, since tbody itself is a block now, it can no longer behave like a table. Since you still need a table behavior to display you columns correctly, the solution is to ask for each of your rows to display as individual tables:

thead {         
   display: table;  
   width: 100%;     // Fill the containing table
}
tbody tr {
   display: table;
   width: 100%;     // Fill the containing table
}

(Note that, using this technique, you won't be able to span across rows anymore).

Once that done, you can enforce column widths to have the same width in both thead and tbody. You could not that:

• individually for each column (through specific CSS classes or inline styling), which is quite tedious to do for each table instance ;
• uniformly for all columns (through th, td { width: 20%; } if you have 5 columns for example), which is more practical (no need to set width for each table instance) but cannot work for any columns count
• uniformly for any columns count, through a fixed table layout.

I prefer the last option, which requires adding:

thead {
   table-layout: fixed;   // Same layout for all cells
}
tbody tr {
   table-layout: fixed;   // Same layout for all cells
}
th, td {
   width: auto;   // Same width for all cells, if table has fixed layout
}    

See a demo here, forked from the answer to this question.

You can remove them from /Library/Developer/CoreSimulator/Profiles/Runtimes (Not ~/Library!):

The command to change the shell at startup is chsh -s <path_to_shell>. The default shells in mac OS X are installed inside the bin directory so if you want to change to the default zsh then you would use the following

chsh -s /bin/zsh

If you're using different version of zsh then you might have to add that version to /etc/shells to avoid the nonstandard shell message. For example if you want home-brew's version of zsh then you have to add /usr/local/bin/zsh to the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" and then run

chsh -s /usr/local/bin/zsh

Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed

sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" && chsh -s /usr/local/bin/zsh

# There is a bug in the next line.  $searchParameters != {} will always return true, because {} is creating
# a new hash reference on the fly, and the inequality operater is comparing the memory location of it
# to the memory location of $searchParameters, and they will always be different. 
# This means that the following code will always get executed as long as $nodes is defined.
# I'm leaving it there because it has always been there, and although I'm sure it was originally meant to
# mean %$searchParameters (essentially "is this hash not empty"), I'm afraid to change it.
if ( $nodes && $searchParameters != {} )

To get the full file path of a selected file or files, then you need to use FileName property for one file or FileNames property for multiple files.

var file = choofdlog.FileName; // for one file

or for multiple files

var files = choofdlog.FileNames; // for multiple files.

To get the directory of the file, you can use Path.GetDirectoryName
Here is Jon Keet's answer to a similar question about getting directories from path

I came across the same issue. I checked out using Tortoise client and then tried to import the projects in Eclipse using import wizard. Eclipse did not recognize the svn location. I tried share option as mentioned in the above posts and it tried to commit these projects into SVN. But my issue was a version mismatch. I selected svn 1.8 version in eclipse (I was using 1.7 in eclipse and 1.8.8 in tortoise) and then re imported the projects. It resolved with no issues.

You can use the :not filter selector:

$('foo:not(".someClass")')

Or not() method:

$('foo').not(".someClass")

If anyone is looking out for using it to apply on the react then you can follow the code pattern given below. You have to add extra property which is rel.

You should not need to access Maven-specific files to get the version information of any given library/class.

You can simply use getClass().getPackage().getImplementationVersion() to get the version information that is stored in a .jar-files MANIFEST.MF. Luckily Maven is smart enough Unfortunately Maven does not write the correct information to the manifest as well by default!

Instead one has to modify the <archive> configuration element of the maven-jar-plugin to set addDefaultImplementationEntries and addDefaultSpecificationEntries to true, like this:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>                   
            <manifest>
                <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
                <addDefaultSpecificationEntries>true</addDefaultSpecificationEntries>
            </manifest>
        </archive>
    </configuration>
</plugin>

Ideally this configuration should be put into the company pom or another base-pom.

Detailed documentation of the <archive> element can be found in the Maven Archive documentation.

There should be one - and preferably only one - obvious way to do it.

Therefore list(dictionary.values()) is the one way.

Yet, considering Python3, what is quicker?

[*L] vs. [].extend(L) vs. list(L)

small_ds = {x: str(x+42) for x in range(10)}
small_df = {x: float(x+42) for x in range(10)}

print('Small Dict(str)')
%timeit [*small_ds.values()]
%timeit [].extend(small_ds.values())
%timeit list(small_ds.values())

print('Small Dict(float)')
%timeit [*small_df.values()]
%timeit [].extend(small_df.values())
%timeit list(small_df.values())

big_ds = {x: str(x+42) for x in range(1000000)}
big_df = {x: float(x+42) for x in range(1000000)}

print('Big Dict(str)')
%timeit [*big_ds.values()]
%timeit [].extend(big_ds.values())
%timeit list(big_ds.values())

print('Big Dict(float)')
%timeit [*big_df.values()]
%timeit [].extend(big_df.values())
%timeit list(big_df.values())

The result

1. For small dictionaries * operator is quicker
2. For big dictionaries where it matters list() is maybe slightly quicker

I recommend you exit the Python interpreter with Ctrl-D. This is the old ASCII code for end-of-file or end-of-transmission.

It's because you're casting to the wrong thing - you're trying to convert to a particular type, and the object that your express refers to is incompatible with that type. For example:

Object x = "this is a string";
InputStream y = (InputStream) x; // This will throw ClassCastException

If you could provide a code sample, that would really help...

To delete column use this,

ALTER TABLE `tbl_Country` DROP `your_col`

On OSX, I used the following, and it worked:

sudo chown -R _www:_www {path to wordpress folder}

_www is the user that PHP runs under on the Mac.

(You may also need to chmod some folders too. I had done that first and it didn't fix it. It wasn't until I did the chown command that it worked, so I'm not sure if it was the chown command alone, or a combination of chmod and chown.)

I recommend setting an alternative location for your npm modules.

npm config set prefix C:\Dev\npm-repository\npm --global 
npm config set cache C:\Dev\npm-repository\npm-cache --global  

Of course you can set the location to wherever best suits.

This has worked well for me and gets around any permissions issues that you may encounter.

You misspelled permission

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

Some more spins on the <a name=""> trick:

<a id="a-link"></a> Title
------

#### <a id="a-link"></a> Title (when you wanna control the h{N} with #'s)

Here is your example re-written to show a stand-alone working example:

class Test:
    def method1(self):
        return 'hello world'

    def method2(self, methodToRun):
        result = methodToRun()
        return result

    def method3(self):
        return self.method2(self.method1)

test = Test()

print test.method3()

For me, this was an issue with cyclic dependencies.

IOW, module A required module B, and module B required module A.

So in module B, require('./A') is an empty object rather than a function.

How to deal with cyclic dependencies in Node.js

In Visual Basic, do this to select a row in a DataGridView; the selected row will appear with a highlighted color but note that the cursor position will not change:

Grid.Rows(0).Selected = True

Do this change the position of the cursor:

Grid.CurrentCell = Grid.Rows(0).Cells(0)

Combining the lines above will position the cursor and select a row. This is the standard procedure for focusing and selecting a row in a DataGridView:

Grid.CurrentCell = Grid.Rows(0).Cells(0)
Grid.Rows(0).Selected = True

This will do:

/^(apple|banana)$/

to exclude from captured strings (e.g. $1,$2):

(?:apple|banana)

I'm on my first Python script, and I was a little confused by the square matrix example so I hope the below example will help you save some time:

 # Creates a 2 x 5 matrix
 Matrix = [[0 for y in xrange(5)] for x in xrange(2)]

so that

Matrix[1][4] = 2 # Valid
Matrix[4][1] = 3 # IndexError: list index out of range

By default they are stored here:
%commonprogramfiles%/Microsoft Shared/web server extensions/12/Logs

Using %commonprogramfiles% make it works in non-english systems.

Rules of thumb for C++11:

Pass by value, except when

1. you do not need ownership of the object and a simple alias will do, in which case you pass by const reference,
2. you must mutate the object, in which case, use pass by a non-const lvalue reference,
3. you pass objects of derived classes as base classes, in which case you need to pass by reference. (Use the previous rules to determine whether to pass by const reference or not.)

Passing by pointer is virtually never advised. Optional parameters are best expressed as a std::optional (boost::optional for older std libs), and aliasing is done fine by reference.

C++11's move semantics make passing and returning by value much more attractive even for complex objects.

Rules of thumb for C++03:

Pass arguments by const reference, except when

1. they are to be changed inside the function and such changes should be reflected outside, in which case you pass by non-const reference
2. the function should be callable without any argument, in which case you pass by pointer, so that users can pass NULL/0/nullptr instead; apply the previous rule to determine whether you should pass by a pointer to a const argument
3. they are of built-in types, which can be passed by copy
4. they are to be changed inside the function and such changes should not be reflected outside, in which case you can pass by copy (an alternative would be to pass according to the previous rules and make a copy inside of the function)

(here, "pass by value" is called "pass by copy", because passing by value always creates a copy in C++03)

There's more to this, but these few beginner's rules will get you quite far.

You can do it using a straight forward select like this:

SELECT * 
FROM sys.indexes 
WHERE name='YourIndexName' AND object_id = OBJECT_ID('Schema.YourTableName')

Since you're using PHP, you will probably need to use the CURLOPT_PORT option, like so:

curl_setopt($ch, CURLOPT_PORT, 11740);

Bear in mind, you may face problems with SELinux:

Unable to make php curl request with port number

No one probably really wants to remove row one. So if you are looking for something meaningful, that is conditional selection

#remove rows that have long length and "0" value for vector E

>> setNew<-set[!(set$length=="long" & set$E==0),]

offsetHeight, usually.

If you need to calculate something but not show it, set the element to visibility:hidden and position:absolute, add it to the DOM tree, get the offsetHeight, and remove it. (That's what the prototype library does behind the scenes last time I checked).

Below code will count Message from 0 to 137 each 0.3 second replacing previous number.

Number of symbol to backstage = number of digits.

stream = sys.stdout
for i in range(137):
    stream.write('\b' * (len(str(i)) + 10))
    stream.write("Message : " + str(i))
    stream.flush()
    time.sleep(0.3)

In Jenkins 2.60.3 there is a way to delete build artifacts (not the archived artifacts) in order to save hard drive space on the build machine. In the General section, check "Discard old builds" with strategy "Log Rotation" and then go into its Advanced options. Two more options will appear related to keeping build artifacts for the job based on number of days or builds.

The settings that work for me are to enter 1 for "Max # of builds to keep with artifacts" and then to have a post-build action to archive the artifacts. This way, all artifacts from all builds will be archived, all information from builds will be saved, but only the last build will keep its own artifacts.

Discard old builds options

From the Java EE documentation:

public abstract boolean unique

(Optional) Whether the property is a unique key. This is a shortcut for the UniqueConstraint annotation at the table level and is useful for when the unique key constraint is only a single field. This constraint applies in addition to any constraint entailed by primary key mapping and to constraints specified at the table level.

See doc

On socket.io >=1.0, after the connect event has triggered:

var socket = io('localhost');
var id = socket.io.engine.id

You can use indexOf(). Like:

var Color = ["blue", "black", "brown", "gold"];
var a = Color.indexOf("brown");
alert(a);

The indexOf() method searches the array for the specified item, and returns its position. And return -1 if the item is not found.

If you want to search from end to start, use the lastIndexOf() method:

    var Color = ["blue", "black", "brown", "gold"];
    var a = Color.lastIndexOf("brown");
    alert(a);

The search will start at the specified position, or at the end if no start position is specified, and end the search at the beginning of the array.

Returns -1 if the item is not found.

Casting should be enough. If you're using C# 3.0 you can make a handy extension method to parse enum values:

public static TEnum ToEnum<TInput, TEnum>(this TInput value)
{
    Type type = typeof(TEnum);

    if (value == default(TInput))
    {
        throw new ArgumentException("Value is null or empty.", "value");
    }

    if (!type.IsEnum)
    {
        throw new ArgumentException("Enum expected.", "TEnum");
    }

    return (TEnum)Enum.Parse(type, value.ToString(), true);
}

I've found a solution worked for me:

const handleDownload = async () => {
   const req = await axios({
     method: "get",
     url: `/companies/${company.id}/data`,
     responseType: "blob",
   });
   var blob = new Blob([req.data], {
     type: req.headers["content-type"],
   });
   const link = document.createElement("a");
   link.href = window.URL.createObjectURL(blob);
   link.download = `report_${new Date().getTime()}.xlsx`;
   link.click();
 };

I just point a responseType: "blob"

Adding executable permissions, recursively, to all files (not folders) within the current folder with sh extension:

find . -name '*.sh' -type f | xargs chmod +x

The jsonlite package is easy to use and tries to convert json into data frames.

Example:

library(jsonlite)

# url with some information about project in Andalussia
url <- 'http://www.juntadeandalucia.es/export/drupaljda/ayudas.json'

# read url and convert to data.frame
document <- fromJSON(txt=url)

There is no need to decompile Applet.class. The public Java API classes sourcecode comes with the JDK (if you choose to install it), and is better readable than decompiled bytecode. You can find compressed in src.zip (located in your JDK installation folder).

number.parseFloat(2) works but it returns a string.

If you'd like to preserve it as a number type you can use:

Math.round(number * 100) / 100

You need to use JSON.stringify to first serialize your object to JSON, and then specify the contentType so your server understands it's JSON. This should do the trick:

$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    contentType: "application/json",
    complete: callback
});

Note that the JSON object is natively available in browsers that support JavaScript 1.7 / ECMAScript 5 or later. If you need legacy support you can use json2.

If the output from ReflectionToStringBuilder.toString() is not enough readable for you, here is code that:
1) sorts field names alphabetically
2) flags non-null fields with asterisks in the beginning of the line

public static Collection<Field> getAllFields(Class<?> type) {
    TreeSet<Field> fields = new TreeSet<Field>(
            new Comparator<Field>() {

test harness:

public static void main(String[] args) {
    A a = new A();
    a.x = 1;
    B b = new B();
    b.x=10;
    b.y=20;
    System.out.println("=======");
    printAllFields(a);
    System.out.println("=======");
    printAllFields(b);
    System.out.println("=======");
}

class A {
    int x;
    String z = "z";
    Integer b;

class B extends A {
    int y;
    private double z = 12345.6;

use of async/await with a transpilers like Babel to get it working in older browsers. You’ll also have to install this Babel preset and polyfill from npm: npm i -D babel-preset-env babel-polyfill.

function getData(ajaxurl) { 
  return $.ajax({
    url: ajaxurl,
    type: 'GET',
  });
};

async test() {
  try {
    const res = await getData('https://api.icndb.com/jokes/random')
    console.log(res)
  } catch(err) {
    console.log(err);
  }
}

test();

or the .then callback is just another way to write the same logic.

getData(ajaxurl).then(function(res) {
    console.log(res)
}

This is still a matplotlib object. Try this:

# <your code here>
locs, labels = plt.xticks()
plt.setp(labels, rotation=45)

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

Assuming the upper is the upper bound and lower is the lower bound, then you can make a random number, r, between the two bounds with:

int r = (int) (Math.random() * (upper - lower)) + lower;

"Core Java" is Sun Microsystem's term, used to refer to Java SE. And there are Java ME and Java EE (J2EE). So this is told in order to differentiate with the Java ME and J2EE. So I feel Core Java is only used to mention J2SE.

Happy learning!

I'm thinking that if you are creating a batch script that relies on the Current Directory being set to the folder that contains the batch file, that you are setting yourself up for trouble when you try to execute the batch file using a fully qualified path as you would from a scheduler.

Better to add this line to your batch file too:

REM Change Current Directory to the location of this batch file 
CD /D %~dp0

unless you are fully qualifying all of your paths.

There is a Todd Menier's comment above that Flurl includes a Url.Combine.

More details:

Url.Combine is basically a Path.Combine for URLs, ensuring one and only one separator character between parts:

var url = Url.Combine(
    "http://MyUrl.com/",
    "/too/", "/many/", "/slashes/",
    "too", "few?",
    "x=1", "y=2"
// result: "http://www.MyUrl.com/too/many/slashes/too/few?x=1&y=2" 

Get Flurl.Http on NuGet:

PM> Install-Package Flurl.Http

Or get the stand-alone URL builder without the HTTP features:

PM> Install-Package Flurl

I think the accepted answer is great, but why don't you do it explicitly? I feel more people would understand your code, and that is in agreement with PEP 8:

max_value = max(my_list)
max_index = my_list.index(max_value)

This method is also about three times faster than the accepted answer:

import random
from datetime import datetime
import operator

def explicit(l):
    max_val = max(l)
    max_idx = l.index(max_val)
    return max_idx, max_val

def implicit(l):
    max_idx, max_val = max(enumerate(l), key=operator.itemgetter(1))
    return max_idx, max_val

if __name__ == "__main__":
    from timeit import Timer
    t = Timer("explicit(l)", "from __main__ import explicit, implicit; "
          "import random; import operator;"
          "l = [random.random() for _ in xrange(100)]")
    print "Explicit: %.2f usec/pass" % (1000000 * t.timeit(number=100000)/100000)

    t = Timer("implicit(l)", "from __main__ import explicit, implicit; "
          "import random; import operator;"
          "l = [random.random() for _ in xrange(100)]")
    print "Implicit: %.2f usec/pass" % (1000000 * t.timeit(number=100000)/100000)

Results as they run in my computer:

Explicit: 8.07 usec/pass
Implicit: 22.86 usec/pass

Other set:

Explicit: 6.80 usec/pass
Implicit: 19.01 usec/pass

The following is aimed at beginners to ASP.Net...

When does it happen?

A postback originates from the client browser. Usually one of the controls on the page will be manipulated by the user (a button clicked or dropdown changed, etc), and this control will initiate a postback. The state of this control, plus all other controls on the page,(known as the View State) is Posted Back to the web server.

What happens?

Most commonly the postback causes the web server to create an instance of the code behind class of the page that initiated the postback. This page object is then executed within the normal page lifecycle with a slight difference (see below). If you do not redirect the user specifically to another page somewhere during the page lifecycle, the final result of the postback will be the same page displayed to the user again, and then another postback could happen, and so on.

Why does it happen?

The web application is running on the web server. In order to process the user’s response, cause the application state to change, or move to a different page, you need to get some code to execute on the web server. The only way to achieve this is to collect up all the information that the user is currently working on and send it all back to the server.

Some things for a beginner to note are...

• The state of the controls on the posting back page are available within the context. This will allow you to manipulate the page controls or redirect to another page based on the information there.
• Controls on a web form have events, and therefore event handlers, just like any other controls. The initialisation part of the page lifecycle will execute before the event handler of the control that caused the post back. Therefore the code in the page’s Init and Load event handler will execute before the code in the event handler for the button that the user clicked.
• The value of the “Page.IsPostBack” property will be set to “true” when the page is executing after a postback, and “false” otherwise.
• Technologies like Ajax and MVC have changed the way postbacks work.

For Mac with Docker Toolbox, ssh into the VM first with docker-machine ssh %VM-NAME% and then check /var/log/docker.log

It bothered me that I could not find an implementation which is both fast and support Unicode strings.

So I made one which supports Unicode strings and still shows as faster (at time of writing) than the currently fastest ascii-only-strings implementations:

https://github.com/gorhill/yamd5.js

Based on Joseph Myers' code, but uses TypedArrays, plus other improvements.

// create table
var dt = new System.Data.DataTable("tableName");

// create fields
dt.Columns.Add("field1", typeof(int));
dt.Columns.Add("field2", typeof(string));
dt.Columns.Add("field3", typeof(DateTime));

// insert row values
dt.Rows.Add(new Object[]{
                123456,
                "test",
                DateTime.Now
           });

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

EDIT: Actually this code above is equivalent to the children selector .sys > input[type=text] if you want the descendant select (.sys input[type=text]) you need to use the options given by @NiftyDude.

More information:

• jQuery.children()
• multiple selector

The case is like :

 mysql connects will localhost when network is not up.
 mysql cannot connect when network is up.

You can try the following steps to diagnose and resolve the issue (my guess is that some other service is blocking port on which mysql is hosted):

1. Disconnect the network.
2. Stop mysql service (if windows, try from services.msc window)
3. Connect to network.
4. Try to start the mysql and see if it starts correctly.
5. Check for system logs anyways to be sure that there is no error in starting mysql service.
6. If all goes well try connecting.
7. If fails, try to do a telnet localhost 3306 and see what output it shows.
8. Try changing the port on which mysql is hosted, default 3306, you can change to some other port which is ununsed.

This should ideally resolve the issue you are facing.

As well as having then on a new line, you also need a space before and after the [, which is a special symbol in BASH.

#!/bin/bash
echo "start\n"
for f in *.jpg
do
  fname=$(basename "$f")
  echo "fname is $fname\n"
  fname="${filename%.*}"
  echo "fname is $fname\n"
  if [ $((fname %  2)) -eq 1 ]
  then
    echo "removing $fname\n"
    rm "$f"
  fi
done

In my case node.js was using some resources in build folder (my app in reactnative). So I killed node.js and it solved.

It looks like you are entering a blank line after the body of the if statement. This is a cue to the interactive compiler that you are done with the block entirely, so it is not expecting any elif/else blocks. Try entering the code exactly like this, and only hit enter once after each line:

if guess == number:
    print('Congratulations! You guessed it.')
elif guess < number:
    pass # Your code here
else:
    pass # Your code here

You could make use of the Javascript DOM API. In particular, look at the createElement() method.

You could create a re-usable function that will create an image like so...

function show_image(src, width, height, alt) {
    var img = document.createElement("img");
    img.src = src;
    img.width = width;
    img.height = height;
    img.alt = alt;

    // This next line will just add it to the <body> tag
    document.body.appendChild(img);
}

Then you could use it like this...

<button onclick=
    "show_image('http://google.com/images/logo.gif', 
                 276, 
                 110, 
                 'Google Logo');">Add Google Logo</button> 

See a working example on jsFiddle: http://jsfiddle.net/Bc6Et/

I saw examples of thread IDs like this:

class myThread(threading.Thread):
    def __init__(self, threadID, name, counter):
        self.threadID = threadID
        ...

The threading module docs lists name attribute as well:

...

A thread has a name. 
The name can be passed to the constructor, 
and read or changed through the name attribute.

...

Thread.name

A string used for identification purposes only. 
It has no semantics. Multiple threads may
be given the same name. The initial name is set by the constructor.

I'm late to the party, but searching for the correct way to do it I came across this page it was one of the top Google search returns, so I will like to share my view on the problem, which I consider it to be up to date at the time of writing this post (beginning of 2017). From PHP 7.1.0 the mcrypt_decrypt and mcrypt_encrypt is going to be deprecated, so building future proof code should use openssl_encrypt and openssl_decrypt

You can do something like:

$string_to_encrypt="Test";
$password="password";
$encrypted_string=openssl_encrypt($string_to_encrypt,"AES-128-ECB",$password);
$decrypted_string=openssl_decrypt($encrypted_string,"AES-128-ECB",$password);

Important: This uses ECB mode, which isn't secure. If you want a simple solution without taking a crash course in cryptography engineering, don't write it yourself, just use a library.

You can use any other chipper methods as well, depending on your security need. To find out the available chipper methods please see the openssl_get_cipher_methods function.

Well, according to Google's lectures (maybe here, I don't remember) , you should consider using Fragments whenever it's possible, as it makes your code easier to maintain and control.

However, I think that on some cases it can get too complex, as the activity that hosts the fragments need to navigate/communicate between them.

I think you should decide by yourself what's best for you. It's usually not that hard to convert an activity to a fragment and vice versa.

I've created a post about this dillema here, if you wish to read some further.

I ran into this while working on a .NET console app to read the PATH environment variable, and found that using System.Environment.GetEnvironmentVariable will expand the environment variables automatically.

I didn't want that to happen...that means folders in the path such as '%SystemRoot%\system32' were being re-written as 'C:\Windows\system32'. To get the un-expanded path, I had to use this:

string keyName = @"SYSTEM\CurrentControlSet\Control\Session Manager\Environment\";
string existingPathFolderVariable = (string)Registry.LocalMachine.OpenSubKey(keyName).GetValue("PATH", "", RegistryValueOptions.DoNotExpandEnvironmentNames);

Worked like a charm for me.

Try not closing the connection before you send data to your database. Remove client.close(); from your code and it'll work fine.

I found the default JS date formatting didn't work.

So I used toLocaleString with options

const event = new Date();
const options = { dateStyle: 'short' };
const date = event.toLocaleString('en', options);

to get: DD/MM/YYYY format

See docs for more formatting options: https://www.w3schools.com/jsref/jsref_tolocalestring.asp

You have several options ;)

$memcache_enabled = class_exists('Memcache');
$memcache_enabled = extension_loaded('memcache');
$memcache_enabled = function_exists('memcache_connect');

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

PHP runs on the server and Javascript runs on the client, so you can't set a PHP variable to equal a Javascript variable without sending the value to the server. You can, however, set a Javascript variable to equal a PHP variable:

<script type="text/javascript">
  var foo = '<?php echo $foo ?>';
</script>

To send a Javascript value to PHP you'd need to use AJAX. With jQuery, it would look something like this (most basic example possible):

var variableToSend = 'foo';
$.post('file.php', {variable: variableToSend});

On your server, you would need to receive the variable sent in the post:

$variable = $_POST['variable'];

I just ran into this problem; the issue seems different from the other answers posted here, so I'll mention it in case it helps someone.

In my case, I have an internal base class defined in one assembly ("A"), an internal derived class defined in a second assembly ("B"), and a test assembly ("TEST"). I exposed internals defined in assembly "B" to "TEST" using InternalsVisibleToAttribute, but neglected to do so for assembly "A". This produced the error mentioned at top with no further indication of the problem; using InternalsVisibleToAttribute to expose assembly "A" to "TEST" resolved the issue.

As long as you're not doing any INSERT or UPDATE statements in your stored procedure, you will probably want to make it a function.

Stored procedures are for executing by an outside program, or on a timed interval.

The answers here will explain it better than I can:

Function vs. Stored Procedure in SQL Server

Here you have an example working on py2.6 and py3.2:

from scipy.stats import norm
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt

# read data from a text file. One number per line
arch = "test/Log(2)_ACRatio.txt"
datos = []
for item in open(arch,'r'):
    item = item.strip()
    if item != '':
        try:
            datos.append(float(item))
        except ValueError:
            pass

# best fit of data
(mu, sigma) = norm.fit(datos)

# the histogram of the data
n, bins, patches = plt.hist(datos, 60, normed=1, facecolor='green', alpha=0.75)

# add a 'best fit' line
y = mlab.normpdf( bins, mu, sigma)
l = plt.plot(bins, y, 'r--', linewidth=2)

#plot
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title(r'$\mathrm{Histogram\ of\ IQ:}\ \mu=%.3f,\ \sigma=%.3f$' %(mu, sigma))
plt.grid(True)

plt.show()

I'm using following markup and had encoutered the same problem:

<ul class="nav">
    <li><a href="abc.html">abc</a></li>
    <li><a href="def.html">def</a></li>
</ul>

Here I have used the following logic:

$(".nav > li").click(function(e){
    if(e.target != this) return; // only continue if the target itself has been clicked
    // this section only processes if the .nav > li itself is clicked.
    alert("you clicked .nav > li, but not it's children");
});

In terms of the exact question, I can see that working as follows:

$(".example").click(function(e){
   if(e.target != this) return; // only continue if the target itself has been clicked
   $(".example").fadeOut("fast");
});

or of course the other way around:

$(".example").click(function(e){
   if(e.target == this){ // only if the target itself has been clicked
       $(".example").fadeOut("fast");
   }
});

Hope that helps.

Another option is to right click on your jar file which would be under (Your Project)->Referenced Libraries->(your jar) and click on properties. Then click on Java Source Attachment. And then in location path put in the location for your source jar file.

This is just another approach to attaching your source file.

You can use Excel Automation (it is basically a COM Base stuff) e.g:

Excel.Application xlApp ;
Excel.Workbook xlWorkBook ;
Excel.Worksheet xlWorkSheet ;


xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Open("1.xls", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

      this.step = step;
    }

    @Override
    public Long call() throws Exception {
      final long LIMIT = Long.MAX_VALUE - this.step;
      final Random random = new Random();
      int position, rnd;

You can't cast an IEnumerable<T> to a List<T>.

But you can accomplish this using LINQ:

var result = ((IEnumerable)myObject).Cast<object>().ToList();

if ($('input.checkbox_check').is(':checked')) {

nor does it appear in the list of environments that can be added when I click the "Add" button. All I see is the J2EE Runtime Library.

Go get "Eclipse for Java EE developers". Note the extra "EE". This includes among others the Web Tools Platform with among others a lot of server plugins with among others the one for Apache Tomcat 5.x. It's also logically; JSP/Servlet is part of the Java EE API.

in a Visual Basic Macro you would use

pName = ActiveWorkbook.Path      ' the path of the currently active file
wbName = ActiveWorkbook.Name     ' the file name of the currently active file
shtName = ActiveSheet.Name       ' the name of the currently selected worksheet

The first sheet in a workbook can be referenced by

ActiveWorkbook.Worksheets(1)

so after deleting the [Report] tab you would use

ActiveWorkbook.Worksheets("Report").Delete
shtName = ActiveWorkbook.Worksheets(1).Name

to "work on that sheet later on" you can create a range object like

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(shtName).[A1]

and continue working on MySheet(rowNum, colNum) etc. ...

shortcut creation of a range object without defining shtName:

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(1).[A1]

Returns true if comes 'y', '1', 'true', 'on'or whatever you add in similar way

boolean getValue(String value) {
  return ("Y".equals(value.toUpperCase()) 
      || "1".equals(value.toUpperCase())
      || "TRUE".equals(value.toUpperCase())
      || "ON".equals(value.toUpperCase()) 
     );
}

Yes you can:

In case you get "Unable to locate tools.jar. Expected to find it in C:\Program Files (x86)\Java\jre6\lib\tools.jar" you can add an environment variable JAVA_HOME that points to your Java JDK path, for example c:\sdks\glassfish3\jdk (restart MSVC afterwards)

An even better solution is using WinGDB Mobile Edition in Visual Studio: it lets you create and debug Android projects all inside Visual Studio:

http://ian-ni-lewis.blogspot.com/2011/01/its-like-coming-home-again.html

Download WinGDC for Android from http://www.wingdb.com/wgMobileEdition.htm

I'd use request for this:

request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))

Or if you don't need to save to a file first, and you just need to read the CSV into memory, you can do the following:

var request = require('request');
request.get('http://www.whatever.com/my.csv', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        var csv = body;
        // Continue with your processing here.
    }
});

etc.

Here is a simple example for others visiting this old post, but is confused by the example in the question and the other answer:

Delivery -> Package (One -> Many)

CREATE TABLE Delivery(
    Id INT IDENTITY PRIMARY KEY,
    NoteNumber NVARCHAR(255) NOT NULL
)

CREATE TABLE Package(
    Id INT IDENTITY PRIMARY KEY,
    Status INT NOT NULL DEFAULT 0,
    Delivery_Id INT NOT NULL,
    CONSTRAINT FK_Package_Delivery_Id FOREIGN KEY (Delivery_Id) REFERENCES Delivery (Id) ON DELETE CASCADE
)

The entry with the foreign key Delivery_Id (Package) is deleted with the referenced entity in the FK relationship (Delivery).

So when a Delivery is deleted the Packages referencing it will also be deleted. If a Package is deleted nothing happens to any deliveries.

Create a file called MoveFiles.bat with the syntax

move c:\Sourcefoldernam\*.* e:\destinationFolder

then schedule a task to run that MoveFiles.bat every 10 hours.

I solved the same problem with these commands:

curl -O https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py

No answers about few files, so:

sort -u file1 file2 -o file1

Sure, you can use equals if you want to go along with the crowd, but if you really want to amaze your fellow programmers check for inequality like this:

if ("success" != statusCheck.intern())

intern method is part of standard Java String API.

You can achieve by data-* attribute like data-replace="replaceTarget,replaceBy" so with help of jQuery to get replaceTarget & replaceBy value by .split() method after getting values then use .replaceWith() method.
This data-* attribute technique to easily manage any tag replacement without changing below (common code for all tag replacement).

I hope below snippet will help you lot.

$(document).on('click', '[data-replace]', function(){_x000D_
  var replaceTarget = $(this).attr('data-replace').split(',')[0];_x000D_
  var replaceBy = $(this).attr('data-replace').split(',')[1];_x000D_
  $(replaceTarget).replaceWith($(replaceBy).html($(replaceTarget).html()));_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<p id="abc">Hello World #1</p>_x000D_
<a href="#" data-replace="#abc,<h1/>">P change with H1 tag</a>_x000D_
<hr>_x000D_
<h2 id="xyz">Hello World #2</h2>_x000D_
<a href="#" data-replace="#xyz,<p/>">H1 change with P tag</a>_x000D_
<hr>_x000D_
<b id="bold">Hello World #2</b><br>_x000D_
<a href="#" data-replace="#bold,<i/>">B change with I tag</a>_x000D_
<hr>_x000D_
<i id="italic">Hello World #2</i><br>_x000D_
<a href="#" data-replace="#italic,<b/>">I change with B tag</a>

You could try using unidecode, which is available as a ruby gem and as a perl module on cpan. Essentially, it works as a huge lookup table, where each unicode code point relates to an ascii character or string.

Using display: fixed on the thead section should work, but for it only work on the current table in view, you will need the help of JavaScript. And it will be tricky because it will need to figure out scrolling places and location of elements relative to the viewport, which is one of the prime areas of browser incompatibility.

Have a look at the popular JavaScript frameworks (jQuery, MooTools, YUI, etc etc.) to see if they can either do what you want or make it easier to do what you want.

Besides the other answers. You should notice these args can give you the file path that was dragged and dropped on the .exe file. i.e if you drag and drop any file on your .exe file then the application will be launched and the arg[0] will contain the file path that was dropped onto it.

static void Main(string[] args)
{
    Console.WriteLine(args[0]);
}

this will print the path of the file dropped on the .exe file. e.g

C:\Users\ABCXYZ\source\repos\ConsoleTest\ConsoleTest\bin\Debug\ConsoleTest.pdb

Hence, looping through the args array will give you the path of all the files that were selected and dragged and dropped onto the .exe file of your console app. See:

static void Main(string[] args)
{
    foreach (var arg in args)
    {
        Console.WriteLine(arg);
    }
    Console.ReadLine();
}

The code sample above will print all the file names that were dragged and dropped onto it, See I am dragging 5 files onto my ConsoleTest.exe app.

And here is the output that I get after that:

To add to the other answers, a common use case I have found for setattr() is when using configs. It is common to parse configs from a file (.ini file or whatever) into a dictionary. So you end up with something like:

configs = {'memory': 2.5, 'colour': 'red', 'charge': 0, ... }

If you want to then assign these configs to a class to be stored and passed around, you could do simple assignment:

MyClass.memory = configs['memory']
MyClass.colour = configs['colour']
MyClass.charge = configs['charge']
...

However, it is much easier and less verbose to loop over the configs, and setattr() like so:

for name, val in configs.items():
    setattr(MyClass, name, val)

As long as your dictionary keys have the proper names, this works very well and is nice and tidy.

*Note, the dict keys need to be strings as they will be the class object names.

This code can help you :

$(document).ready(function() { 
    $('#calendar').fullCalendar({ 
        events: 
            [ 
                { 
                    id: 1, 
                    title: 'First Event', 
                    start: ..., 
                    end: ..., 
                    description: 'first description' 
                }, 
                { 
                    id: 2, 
                    title: 'Second Event', 
                    start: ..., 
                    end: ..., 
                    description: 'second description'
                }
            ], 
        eventRender: function(event, element) { 
            element.find('.fc-title').append("<br/>" + event.description); 
        } 
    });
}   

This is a better general purpose answer. This function will print all group names and values, or optionally selects one or more groups for display.

def print_pd_groupby(X, grp=None):
    '''Display contents of a Panda groupby object
    :param X: Pandas groupby object
    :param grp: a list with one or more group names
    '''
    if grp is None:
        for k,i in X:
            print("group:", k)
            print(i)
    else:
        for j in grp:
            print("group:", j)
            print(X.get_group(j))

In your example case, here's session output

In [116]: df = pd.DataFrame({'A': ['one', 'one', 'two', 'three', 'three', 'one'], 'B': range(6)})

In [117]: dfg = df.groupby('A')

In [118]: print_pd_groupby(dfg)
group: one
     A  B
0  one  0
1  one  1
5  one  5
group: three
       A  B
3  three  3
4  three  4
group: two
     A  B
2  two  2

In [119]: print_pd_groupby(dfg, grp = ["one", "two"])
group: one
     A  B
0  one  0
1  one  1
5  one  5
group: two
     A  B
2  two  2

This is a better answer because a function is re-usable content, put it in your package or function collection and never re-write that "scriptish" approach again.

IMHO, something like this should be a built in method in Pandas groupby.

If you're looking to make the elements be 33.3% only on small devices and lower:

This is backwards from what Bootstrap is designed for, but you can do this:

<div class="row">
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
</div>

This will make each element 33.3% wide on small and extra small devices but 100% wide on medium and larger devices.

JSFiddle: http://jsfiddle.net/jdwire/sggt8/embedded/result/

If you're only looking to hide elements for smaller devices:

I think you're looking for the visible-xs and/or visible-sm classes. These will let you make certain elements only visible to small screen devices.

For example, if you want a element to only be visible to small and extra-small devices, do this:

<div class="visible-xs visible-sm">You're using a fairly small device.</div>

To show it only for larger screens, use this:

<div class="hidden-xs hidden-sm">You're probably not using a phone.</div>

See http://getbootstrap.com/css/#responsive-utilities-classes for more information.

You can have one alternative of using placeholders as:

@Query("Select c from Registration c where c.place LIKE  %?1%")
List<Registration> findPlaceContainingKeywordAnywhere(String place);

I was able to fix it with the help of following headers

Access-Control-Allow-Origin
Access-Control-Allow-Headers
Access-Control-Allow-Credentials
Access-Control-Allow-Methods

If you are on Nodejs, here is the code you can copy/paste.

app.use((req, res, next) => {
  res.header('Access-Control-Allow-Origin','*');
  res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
  res.header('Access-Control-Allow-Credentials', true);
  res.header('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH');
  next();
});

GUI Option:

1. Open System Properties

   a. Type it in the Start Menu

   b. Use the keyboard shortcut Win+Pause)

   c. From Windows Explorer address bar go to

   %windir%\System32\SystemPropertiesProtection.exe

   d. Write SystemPropertiesProtection in run window and press Enter

2. Switch to the Advanced tab

3. Click Environment Variables
4. Select PATH in the System variables section
5. Click Edit
6. Add python's path to the end of the list (the paths are separated by semicolons).

For example:

C:\Windows;C:\Windows\System32;C:\Python27

Command Line Option:

1. Run Command Prompt as administrator

2. Check existing paths under PATH variable (the paths are separated by semicolons). If your python folder already listed then no need to add again. Default python folder is C:\Python27

   C:\Windows\system32>path or C:\Windows\system32>echo %PATH%

3. Append python path using setx command. The /M option sets the variable at SYSTEM scope.

The default behavior is to set it for the USER.

C:\Windows\system32>setx /M PATH "%PATH%;C:\Python27"

My solution to this problem is to save the length of the array into a struct Array as a meta-information about the array.

#include <stdio.h>
#include <stdlib.h>

struct Array
{
    int length;

    double *array;
};

typedef struct Array Array;

Array* NewArray(int length)
{
    /* Allocate the memory for the struct Array */
    Array *newArray = (Array*) malloc(sizeof(Array));

    /* Insert only non-negative length's*/
    newArray->length = (length > 0) ? length : 0;

    newArray->array = (double*) malloc(length*sizeof(double));

    return newArray;
}

void SetArray(Array *structure,int length,double* array)
{
    structure->length = length;
    structure->array = array;
}

void PrintArray(Array *structure)
{       
    if(structure->length > 0)
    {
        int i;
        printf("length: %d\n", structure->length);
        for (i = 0; i < structure->length; i++)
            printf("%g\n", structure->array[i]);
    }
    else
        printf("Empty Array. Length 0\n");
}

int main()
{
    int i;
    Array *negativeTest, *days = NewArray(5);

    double moreDays[] = {1,2,3,4,5,6,7,8,9,10};

    for (i = 0; i < days->length; i++)
        days->array[i] = i+1;

    PrintArray(days);

    SetArray(days,10,moreDays);

    PrintArray(days);

    negativeTest = NewArray(-5);

    PrintArray(negativeTest);

    return 0;
}

But you have to care about set the right length of the array you want to store, because the is no way to check this length, like our friends massively explained.

I am brand new to WindowBuilder, and, in fact, just getting back into Java after a few years, but I implemented "something", then thought I'd look it up and came across this thread.

I'm in the middle of testing this, so, based on being new to all this, I'm sure I must be missing something.

Here's what I did, where "runTxt" is a textbox and "runName" is a data member of the class:

public void focusGained(FocusEvent e) {
    if (e.getSource() == runTxt) {
        System.out.println("runTxt got focus");
        runTxt.selectAll();
    }
}

public void focusLost(FocusEvent e) {
    if (e.getSource() == runTxt) {
        System.out.println("runTxt lost focus");
        if(!runTxt.getText().equals(runName))runName= runTxt.getText();
        System.out.println("runText.getText()= " + runTxt.getText() + "; runName= " + runName);
    }
}

Seems a lot simpler than what's here so far, and seems to be working, but, since I'm in the middle of writing this, I'd appreciate hearing of any overlooked gotchas. Is it an issue that the user could enter & leave the textbox w/o making a change? I think all you've done is an unnecessary assignment.

You don't need anything special for adding paramaters. Just like you had it.

Route::get('groups/(:any)', array('as' => 'group', 'uses' => 'groups@show'));


class Groups_Controller extends Base_Controller {

    public $restful = true;    

    public function get_show($groupID) {
        return 'I am group id ' . $groupID;
    }  


}

You can do it this way in python3:

print(a,b,end=" ")

we can add attribute width directly to th

eg:

<ng-container matColumnDef="position" >
    <th mat-header-cell *matHeaderCellDef width ="20%"> No. </th>
    <td mat-cell *matCellDef="let element"> {{element.position}} </td>
  </ng-container>

Another alternative is to nest conditions

<ng-container *ngIf="foo === 1;else second"></ng-container>
<ng-template #second>
    <ng-container *ngIf="foo === 2;else third"></ng-container>
</ng-template>
<ng-template #third></ng-template>

Late response, but I think it will help others.

Part of imitating system("pause") is imitating what it asks the user to do: "Press any key to continue . . . " So, we need something that does not wait for simply a return as std::cin.get() would do. Even getch() has its problems when used twice (the second time call has been noticed to skip pausing generally if it's immediately paused again afterwards on the same key press). I think it has to do with the input buffer. System("pause") is usually not recommended, but we still need something to imitate what users might already expect. I prefer getch() because it doesn't echo to the screen, and it works dynamically.

The solution is to do the following using a do-while loop:

void Console::pause()
{ 
    int ch = 0;

    std::cout << "\nPress any key to continue . . . ";

    do {
        ch = getch();
    } while (ch != 0);

    std::cout << std::endl;
} 

Now it waits for the user to press any key. If it's used twice, it waits for the user again instead of skipping.

I like this example:

class A: 
    foo = []
a, b = A(), A()
a.foo.append(5)
b.foo
ans: [5]

class A: 
    def __init__(self): 
        self.foo = []
a, b = A(), A()
a.foo.append(5)
b.foo
ans: []

The onMessageReceived method is fired only when app is in foreground or the notification payload only contains the data type.

From the Firebase docs

For downstream messaging, FCM provides two types of payload: notification and data.

For notification type, FCM automatically displays the message to end-user devices on behalf of the client app. Notifications have a predefined set of user-visible keys.
For data type, client app is responsible for processing data messages. Data messages have only custom key-value pairs.

Use notifications when you want FCM to handle displaying a notification on your client app's behalf. Use data messages when you want your app to handle the display or process the messages on your Android client app, or if you want to send messages to iOS devices when there is a direct FCM connection.

Further down the docs

App behaviour when receiving messages that include both notification and data payloads depends on whether the app is in the background or the foreground—essentially, whether or not it is active at the time of receipt.
When in the background, apps receive the notification payload in the notification tray, and only handle the data payload when the user taps on the notification.
When in the foreground, your app receives a message object with both payloads available.

If you are using the firebase console to send notifications, the payload will always contain the notification type. You have to use the Firebase API to send the notification with only the data type in the notification payload. That way your app is always notified when a new notification is received and the app can handle the notification payload.

If you want to play notification sound when app is in background using the conventional method, you need to add the sound parameter to the notification payload.

You are specifying the -i option:

-i, --include

(HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, HTTP-version and more...

Simply remove that option from your command line:

response=$(curl -sb -H "Accept: application/json" "http://host:8080/some/resource")

The way to go with javascript:

var data = new FormData();

$.each($("input[type='file']")[0].files, function(i, file) {
    data.append('file', file);
});

$.ajax({
    type: 'POST',
    url: '/your/url',
    cache: false,
    contentType: false,
    processData: false,
    data : data,
    success: function(result){
        console.log(result);
    },
    error: function(err){
        console.log(err);
    }
})

If you call data.append('file', file) multiple times your request will contain an array of your files.

From MDN web docs:

"The append() method of the FormData interface appends a new value onto an existing key inside a FormData object, or adds the key if it does not already exist. The difference between FormData.set and append() is that if the specified key already exists, FormData.set will overwrite all existing values with the new one, whereas append() will append the new value onto the end of the existing set of values."

Myself using node.js and multipart handler middleware multer get the data as follows:

router.post('/trip/save', upload.array('file', 10), function(req, res){
    // Your array of files is in req.files
}

I had this issue and found that the installation of the newer openssl did actually work, but my PATH was setup incorrectly for it -- my $PATH had the ports path placed before my brew path so it always found the older version of openssl.

The fix for me was to put the path to brew (/usr/local/bin) at the front of my $PATH.

To find out where you're loading openssl from, run which openssl and note the output. It will be the location of the version your system is using when you run openssl. Its going to be somewhere other than the brewpath of "/usr/local/bin". Change your $PATH, close that terminal tab and open a new one, and run which openssl. You should see a different path now, probably under /usr/local/bin. Now run openssl version and you should see the new version you installed "OpenSSL 1.0.1e 11 Feb 2013".

My solution might not be the cleanest but it should work with no problems. The logic is simply to create a static variable to store your data on the Service and update your view each second on your Activity.

Let's say that you have a String on your Service that you want to send it to a TextView on your Activity. It should look like this

Your Service:

public class TestService extends Service {
    public static String myString = "";
    // Do some stuff with myString

Your Activty:

public class TestActivity extends Activity {
    TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        tv = new TextView(this);
        setContentView(tv);
        update();
        Thread t = new Thread() {
            @Override
            public void run() {
                try {
                    while (!isInterrupted()) {
                        Thread.sleep(1000);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                update();
                            }
                        });
                    }
                } catch (InterruptedException ignored) {}
            }
        };
        t.start();
        startService(new Intent(this, TestService.class));
    }
    private void update() {
        // update your interface here
        tv.setText(TestService.myString);
    }
}

Use single quotation marks ('):

var val = '@ViewBag.ForSection';
alert(val);

I know this is an old post. But here is how I have done it:

    public Form1(string myFile)
    {
        InitializeComponent();
        this.Show();
        if (myFile != null)
        {
            OpenFile(myFile);
        }
    }

    private void OpenFile(string myFile = null)
    {
            MessageBox.Show(myFile);
    }

For mysqlnd only:

 mysqli_options($conn, MYSQLI_OPT_INT_AND_FLOAT_NATIVE, true);

Otherwise:

  $row = $result->fetch_assoc();

  while ($field = $result->fetch_field()) {
    switch (true) {
      case (preg_match('#^(float|double|decimal)#', $field->type)):
        $row[$field->name] = (float)$row[$field->name];
        break;
      case (preg_match('#^(bit|(tiny|small|medium|big)?int)#', $field->type)):
        $row[$field->name] = (int)$row[$field->name];
        break;
    }
  }

Try the following:

foo(*values)

This can be found in the Python docs as Unpacking Argument Lists.

If anyone is following all the steps and having no success, make sure that you are using the correct user. I was attempting to use "ec2-user" but I needed to use "ubuntu."

The date function can return this if you specify the format correctly:

$daynum = date("w", strtotime("wednesday"));

will return 0 for Sunday through to 6 for Saturday.

An alternative format is:

$daynum = date("N", strtotime("wednesday"));

which will return 1 for Monday through to 7 for Sunday (this is the ISO-8601 represensation).

It's quite simple,

We just have to install the flutter toast package. Refer the following documentation: https://pub.dev/packages/fluttertoast

In the installing tab you will get the dependency which you have to paste it in the pubspec.yaml andthen install.

After this just import the package:

import 'package:fluttertoast/fluttertoast.dart';

Similar to above line.

And then by using FlutterToast class you can use your fluttertoast.

You're Done!!!

It's something they've built themselves - it's called Bigtable.

http://en.wikipedia.org/wiki/BigTable

There is a paper by Google on the database:

delegates are the best option for sending data from one form to another.

public partial class frmImportContact : Form
{
     public delegate void callback_data(string someData);
    public event callback_data getData_CallBack;

    private void button_Click(object sender, EventArgs e)
    {
      string myData = "Top Secret Data To Share";
      getData_CallBack(myData);
    }

}

public partial class frmHireQuote : Form
{
     private void Button_Click(object sender, EventArgs e)
    {

      frmImportContact obj = new frmImportContact();
      obj.getData_CallBack += getData;
    }

    private void getData(string someData)
    {
         MessageBox.Show("someData");
    }
}

Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax() method. Or if you wanted to do it using plain javascript, here's a tutorial.

How about like this

public static MvcHtmlString HiddenFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, object value, object htmlAttributes)
    {
        return HiddenFor(htmlHelper, expression, value, HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes));
    }

    public static MvcHtmlString HiddenFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, object value, IDictionary<string, object> htmlAttributes)
    {
        return htmlHelper.Hidden(ExpressionHelper.GetExpressionText(expression), value, htmlAttributes);
    }

Use it like this

 @Html.HiddenFor(customerId => reviewModel.CustomerId, Site.LoggedInCustomerId, null)

You can also create shapes directly inside the item tag, in case you want to add some more details to your view, like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid android:color="#81ba73" />
            <corners android:radius="6dp" />
        </shape>
        <ripple android:color="#c62828"/>
    </item>
    <item android:state_enabled="false">
        <shape>
            <solid android:color="#788e73" />
            <corners android:radius="6dp" />
        </shape>
    </item>
    <item>
        <shape>
            <solid android:color="#add8a3" />
            <corners android:radius="6dp" />
        </shape>
    </item>
</selector>

Beware that Android will cycle through the items from top to bottom, therefore, you must place the item without condition on the bottom of the list (so it acts like a default/fallback).

use this..

@"(?></?\w+)(?>(?:[^>'""]+|'[^']*'|""[^""]*"")*)>"

With the newer Java versions (i.e., Java 9 and forwards) you can use :

Map.of(1, new Point2D.Double(50, 50), 2, new Point2D.Double(100, 50), ...)

generically:

Map.of(Key1, Value1, Key2, Value2, KeyN, ValueN)

Bear in mind however that Map.of only works for at most 10 entries, if you have more than 10 entries that you can use :

Map.ofEntries(entry(1, new Point2D.Double(50, 50)), entry(2,  new Point2D.Double(100, 50)), ...);

     The above answers are also the ways to fix the error but if does not work for anyone  then i have an option...

Just Close the project and nothing else and start it again so it will load References... Follow the ScreenShots.

ok, Im using mac to generate my self signed keys. Here is the working method I used.

I created a shell script to speed up my key generation.

genkey.sh

#/bin/sh

ssh-keygen -f host.key
openssl req -new -key host.key -out request.csr
openssl x509 -req -days 99999 -in request.csr -signkey host.key -out server.crt
openssl pkcs12 -export -inkey host.key -in server.crt -out private_public.p12 -name "SslCert"
openssl base64 -in private_public.p12 -out Base64.key

add the +x execute flag to the script

chmod +x genkey.sh

then call genkey.sh

./genkey.sh

I enter a password (important to include a password at least for the export at the end)

Enter pass phrase for host.key:
Enter Export Password:   {Important to enter a password here}
Verifying - Enter Export Password: { Same password here }

I then take everything in Base64.Key and put it into a string named sslKey

private string sslKey = "MIIJiAIBA...................................." +
                        "......................ETC...................." +
                        "......................ETC...................." +
                        "......................ETC...................." +
                        ".............ugICCAA=";

I then used a lazy load Property getter to get my X509 Cert with a private key.

X509Certificate2 _serverCertificate = null;
X509Certificate2 serverCertificate{
    get
    {
        if (_serverCertificate == null){
            string pass = "Your Export Password Here";
            _serverCertificate = new X509Certificate(Convert.FromBase64String(sslKey), pass, X509KeyStorageFlags.Exportable);
        }
        return _serverCertificate;
    }
}

I wanted to go this route because I am using .net 2.0 and Mono on mac and I wanted to use vanilla Framework code with no compiled libraries or dependencies.

My final use for this was the SslStream to secure TCP communication to my app

SslStream sslStream = new SslStream(serverCertificate, false, SslProtocols.Tls, true);

I hope this helps other people.

NOTE

Without a password I was unable to correctly unlock the private key for export.

The error occurs in 'libcurl', which is the underlying protocol for https upload. Solution is to somehow updgrade libcurl. To get more details about the error, set GIT_CURL_VERBOSE=1

https://confluence.atlassian.com/pages/viewpage.action?pageId=306348908

Meaning of error, as per libcurl doc: CURLE_HTTP_RETURNED_ERROR (22)

This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server returns an error code that is >= 400.

From this post:

To get the entire PC CPU and Memory usage:

using System.Diagnostics;

Then declare globally:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Processor", "% Processor Time", "_Total"); 

Then to get the CPU time, simply call the NextValue() method:

this.theCPUCounter.NextValue();

This will get you the CPU usage

As for memory usage, same thing applies I believe:

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Memory", "Available MBytes");

Then to get the memory usage, simply call the NextValue() method:

this.theMemCounter.NextValue();

For a specific process CPU and Memory usage:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Process", "% Processor Time",              
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Process", "Working Set",
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?

To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters

The difference between Processor\% Processor Time and Process\% Processor Time is Processor is from the PC itself and Process is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters

An alternative to using the Performance Counter

Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.

You can try following code:

foreach ($arry as $key => $value) 
{
      echo $key;
      foreach ($value as  $val) 
      {
         echo $val; 
      }
}

This does the trick...

<item >
    <shape android:shape="rectangle">
        <solid android:color="#YOUR_BOTTOM_LINE_COLOR"/>
    </shape>
</item>

<item android:bottom="1.5dp">
    <shape android:shape="rectangle">
        <solid android:color="#YOUR_BG_COLOR"/>
    </shape>
</item>

For users of VSCodeVim you can do

• You can replace " with whatever you would like to wrap by.
• You can replace w with any other selection operator

The Bootstrap team seems to have removed it. See here: https://github.com/twbs/bootstrap/issues/8922 . @Skelly's answer involves custom css which I didn't want to do so I used the grid system and nav-pills. It worked fine and looked great. The code looks like so:

<div class="row">

  <!-- Navigation Buttons -->
  <div class="col-md-3">
    <ul class="nav nav-pills nav-stacked" id="myTabs">
      <li class="active"><a href="#home" data-toggle="pill">Home</a></li>
      <li><a href="#profile" data-toggle="pill">Profile</a></li>
      <li><a href="#messages" data-toggle="pill">Messages</a></li>
    </ul>
  </div>

  <!-- Content -->
  <div class="col-md-9">
    <div class="tab-content">
      <div class="tab-pane active" id="home">Home</div>
      <div class="tab-pane" id="profile">Profile</div>
      <div class="tab-pane" id="messages">Messages</div>
    </div>
  </div>

</div>

You can see this in action here: http://bootply.com/81948

[Update] @SeanK gives the option of not having to enable the nav-pills through Javascript and instead using data-toggle="pill". Check it out here: http://bootply.com/96067. Thanks Sean.

Despite the other plausible-sounding answers that suggest changing the code page to 65001, that does not work. (Also, changing the default encoding using sys.setdefaultencoding is not a good idea.)

See this question for details and code that does work.

This is the only one that fixed it for me :

createuser -s -U $USER

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

In Kotlin, if you want to create the local constants which are supposed to be used with in the class then you can create it like below

val MY_CONSTANT = "Constants"

And if you want to create a public constant in kotlin like public static final in java, you can create it as follow.

companion object{

     const val MY_CONSTANT = "Constants"

}

I had a similar error "Specified cast is not valid" restoring from SQL Server 2012 to SQL Server 2008 R2

First I got the MDF and LDF Names:

GO

Second I restored with a MOVE using those names returned:

   MOVE 'JQueryExampleDB_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Davincis3.ldf', 
REPLACE
GO  

I have no clue as to the name "JQueryExampleDb", but this worked for me.

Nevertheless, backups (and databases) are not backwards compatible with older versions.

This generally means you haven't properly set up locales on your Linux box.

On Debian or Ubuntu, that means you need to do

$ sudo locale-gen
$ sudo dpkg-reconfigure locales

See also man locale-gen.

Use: ALTER TABLE mytable MODIFY mycolumn VARCHAR(255);

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

The loop in your code is only an over-simplified example, right?

It would be better to create the PreparedStatement only once, and re-use it over and over again in the loop.

In situations where that is not possible (because it complicated the program flow too much), it is still beneficial to use a PreparedStatement, even if you use it only once, because the server-side of the work (parsing the SQL and caching the execution plan), will still be reduced.

To address the situation that you want to re-use the Java-side PreparedStatement, some JDBC drivers (such as Oracle) have a caching feature: If you create a PreparedStatement for the same SQL on the same connection, it will give you the same (cached) instance.

About multi-threading: I do not think JDBC connections can be shared across multiple threads (i.e. used concurrently by multiple threads) anyway. Every thread should get his own connection from the pool, use it, and return it to the pool again.

That's because you have the Date in American format in line[i] and UK format in the FormatString.

11/20/2011
M / d/yyyy

I'm guessing you might need to change the FormatString to:

"M/d/yyyy h:mm"

I have just come across this from Common Crawl.

Might be the answer we are all looking for!!

Here is how I do it by using HashSet

        HashSet<String> hs = new HashSet<string>(new String[] { "Pluto", "Earth", "Neptune" });
        String[] arr =
        {
            "Pluto",
            "Earth",
            "Neptune",
            "Jupiter",
            "Saturn",
            "Mercury",
            "Pluto",
            "Earth",
            "Neptune",
            "Jupiter",
            "Saturn",
            "Mercury",
            // etc.
        };
        ICollection<String> coll = arr;

        String[] arrStrFiltered = coll.Where(str => hs.Contains(str)).ToArray();

HashSet is basically almost to O(1) so your complexity remains O(n).

Use .remove()

$("#yourtableid tr").remove();

If you want to keep the data for future use even after removing it then you can use .detach()

$("#yourtableid tr").detach();

If the rows are children of the table then you can use child selector instead of descendant selector, like

$("#yourtableid > tr").remove();

GROUP BY can be selected from Total row in query design view in MS Access.
If Total row not shown in design view (as in my case). You can go to SQL View and add GROUP By fname etc. Then Total row will automatically show in design view.
You have to select as Expression in this row for calculated fields.

That is the class name and System.identityHashCode() separated by the '@' character. What the identity hash code represents is implementation-specific. It often is the initial memory address of the object, but the object can be moved in memory by the VM over time. So (briefly) you can't rely on it being anything.

Getting the memory addresses of variables is meaningless within Java, since the JVM is at liberty to implement objects and move them as it seems fit (your objects may/will move around during garbage collection etc.)

Integer.toBinaryString() will give you an integer in binary form.

1. Stop the server then run php artisan cache:clear.
2. Start the server and should work now

You are checking Parent properties for null in your delegate. The same should work with lambda expressions too.

List<AnalysisObject> analysisObjects = analysisObjectRepository
        .FindAll()
        .Where(x => 
            (x.ID == packageId) || 
            (x.Parent != null &&
                (x.Parent.ID == packageId || 
                (x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
        .ToList();

>> /dev/null redirects standard output (stdout) to /dev/null, which discards it.

(The >> seems sort of superfluous, since >> means append while > means truncate and write, and either appending to or writing to /dev/null has the same net effect. I usually just use > for that reason.)

2>&1 redirects standard error (2) to standard output (1), which then discards it as well since standard output has already been redirected.

To rephrase Jarret Meyer's answer, you need to change the parameter name to 'id' or add a route like this:

routes.MapRoute(
        "ViewStockNext", // Route name
        "Inventory/ViewStockNext/{firstItem}",  // URL with parameters
        new { controller = "Inventory", action = "ViewStockNext" }  // Parameter defaults
    );

The reason is the default route only looks for actions with no parameter or a parameter called 'id'.

Edit: Heh, nevermind Jarret added a route example after posting.

It depends. If the exact answer really matters, do some profiling and find out. If you're sure you'll never have more than a certain number of elements in the set, go with a List. If the number is unbounded, use a HashSet.

Lets analyze this patch line by line.

• The first line

  diff --git a/builtin-http-fetch.c b/http-fetch.c

  is a "git diff" header in the form diff --git a/file1 b/file2. The a/ and b/ filenames are the same unless rename/copy is involved (like in our case). The --git is to mean that diff is in the "git" diff format.

• Next are one or more extended header lines. The first three

  similarity index 95%
  rename from builtin-http-fetch.c
  rename to http-fetch.c

  tell us that the file was renamed from builtin-http-fetch.c to http-fetch.c and that those two files are 95% identical (which was used to detect this rename).
  
  The last line in extended diff header, which is

  index f3e63d7..e8f44ba 100644

  tell us about mode of given file (100644 means that it is ordinary file and not e.g. symlink, and that it doesn't have executable permission bit), and about shortened hash of preimage (the version of file before given change) and postimage (the version of file after change). This line is used by git am --3way to try to do a 3-way merge if patch cannot be applied itself.
  
  

• Next is two-line unified diff header

  --- a/builtin-http-fetch.c
  +++ b/http-fetch.c

  Compared to diff -U result it doesn't have from-file-modification-time nor to-file-modification-time after source (preimage) and destination (postimage) file names. If file was created the source is /dev/null; if file was deleted, the target is /dev/null.
  If you set diff.mnemonicPrefix configuration variable to true, in place of a/ and b/ prefixes in this two-line header you can have instead c/, i/, w/ and o/ as prefixes, respectively to what you compare; see git-config(1)

• Next come one or more hunks of differences; each hunk shows one area where the files differ. Unified format hunks starts with line like

  @@ -1,8 +1,9 @@

  or

  @@ -18,6 +19,8 @@ int cmd_http_fetch(int argc, const char **argv, ...

  It is in the format @@ from-file-range to-file-range @@ [header]. The from-file-range is in the form -<start line>,<number of lines>, and to-file-range is +<start line>,<number of lines>. Both start-line and number-of-lines refer to position and length of hunk in preimage and postimage, respectively. If number-of-lines not shown it means that it is 0.

  The optional header shows the C function where each change occurs, if it is a C file (like -p option in GNU diff), or the equivalent, if any, for other types of files.

• Next comes the description of where files differ. The lines common to both files begin with a space character. The lines that actually differ between the two files have one of the following indicator characters in the left print column:

  • '+' -- A line was added here to the first file.
  • '-' -- A line was removed here from the first file.

  
  So, for example, first chunk

   #include "cache.h"
   #include "walker.h"
  
  -int cmd_http_fetch(int argc, const char **argv, const char *prefix)
  +int main(int argc, const char **argv)
   {
  +       const char *prefix;
          struct walker *walker;
          int commits_on_stdin = 0;
          int commits;
  

  means that cmd_http_fetch was replaced by main, and that const char *prefix; line was added.

  In other words, before the change, the appropriate fragment of then 'builtin-http-fetch.c' file looked like this:

  #include "cache.h"
  #include "walker.h"
  
  int cmd_http_fetch(int argc, const char **argv, const char *prefix)
  {
         struct walker *walker;
         int commits_on_stdin = 0;
         int commits;
  

  After the change this fragment of now 'http-fetch.c' file looks like this instead:

  #include "cache.h"
  #include "walker.h"
  
  int main(int argc, const char **argv)
  {
         const char *prefix;
         struct walker *walker;
         int commits_on_stdin = 0;
         int commits;
  

• There might be

  \ No newline at end of file

  line present (it is not in example diff).

As Donal Fellows said it is best to practice reading diffs on real-life examples, where you know what you have changed.

References:

• git-diff(1) manpage, section "Generating patches with -p"
• (diff.info)Detailed Unified node, "Detailed Description of Unified Format".

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

int min = 65;
int max = 80;

Random r = new Random();
int i1 = r.nextInt(max - min + 1) + min;

Note that nextInt(int max) returns an int between 0 inclusive and max exclusive. Hence the +1.

In my case the solution was quite simple. I added this header and the browsers opened the file in every test. header('Content-Disposition: attachment; filename="filename.pdf"');

I think the best method out there is to implement the SIGAR API by Hyperic. It works for most of the major operating systems ( darn near anything modern ) and is very easy to work with. The developer(s) are very responsive on their forum and mailing lists. I also like that it is GPL2 Apache licensed. They provide a ton of examples in Java too!

SIGAR == System Information, Gathering And Reporting tool.

Here's another use case, if you would like to copy the current url to your clipboard:

Define a method

const copyToClipboard = e => {
  navigator.clipboard.writeText(window.location.toString())
}

Call that method

<button copyToClipboard={shareLink}>
   Click to copy current url to clipboard
</button>

you can use map function

 toArray= fromArray.map(x => x);

You need to import the module datetime first:

>>> import datetime

After that it works:

>>> import datetime
>>> date = datetime.date.today()
>>> date
datetime.date(2013, 11, 12)

Somebody already mentioned above. I'll just post a short version.

To merge two JSONObject json1 & json2 You could simply deal it with String like this:

String merged = json1.toString().substring(0, json1.length() - 1) + "," +
json2.toString().substring(1);
JSONObject mergedJson = new JSONObject(merged);

Of course, do not forget deal with JSONException. :) Hope this could help you.

var winWidth = window.screen.width;
var winHeight = window.screen.height;

document.write(winWidth, winHeight);

Pass the File object to the constructor PrintWriter(File file):

PrintWriter printWriter = new PrintWriter(file);

None of the up-voted answers work for me. Finally I pass the credentials inside the python script, using the client API.

import boto3
client = boto3.client(
's3',
aws_access_key_id=ACCESS_KEY,
aws_secret_access_key=SECRET_KEY,
aws_session_token=SESSION_TOKEN)

Please notice that the aws_session_token argument is optional. Not recommended for public work, but make life easier for simple trial.

I made a POC for an Angular application using multiple modules and router-outlets to nest sub apps in a single page app. You can get the source code at: https://github.com/AhmedBahet/ng-sub-apps

Hope this will help

In my case, I am not using the built in ajax api to feed Json to the table (this is due to some formatting that was rather difficult to implement inside the datatable's render callback).

My solution was to create the variable in the outer scope of the onload functions and the function that handles the data refresh (var table = null, for example).

Then I instantiate my table in the on load method

$(function () {
            //.... some code here
            table = $("#detailReportTable").DataTable();
            .... more code here
        });

and finally, in the function that handles the refresh, i invoke the clear() and destroy() method, fetch the data into the html table, and re-instantiate the datatable, as such:

function getOrderDetail() {
            table.clear();
            table.destroy();
            ...
            $.ajax({
             //.....api call here
            });
            ....
            table = $("#detailReportTable").DataTable();
   }

I hope someone finds this useful!

You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:

newpath = r'C:\Program Files\arbitrary' 
if not os.path.exists(newpath):
    os.makedirs(newpath)

If you're trying to make an installer: Windows Installer does a lot of work for you.

Please read the other answers and comments, there’s a lot more information stated and nuances described (hash functions?) that I did not know when I answered this question.

According to Jenkins' own help (the "?" button) for the schedule task, 5 fields are specified:

This field follows the syntax of cron (with minor differences). Specifically, each line consists of 5 fields separated by TAB or whitespace: MINUTE HOUR DOM MONTH DOW

I just tried to get a job to launch at 4:42PM (my approximate local time) and it worked with the following, though it took about 30 extra seconds:

42 16 * * *

If you want multiple times, I think the following should work:

0 16,18,20,22 * * *

for 4, 6, 8, and 10 o'clock PM every day.

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

I think using the broadcast in numpy is the best, and faster

I did a compare as following

import numpy as np
b = np.random.randn(1000)
In [105]: %timeit c = np.tile(b[:, newaxis], (1,100))
1000 loops, best of 3: 354 µs per loop

In [106]: %timeit c = np.repeat(b[:, newaxis], 100, axis=1)
1000 loops, best of 3: 347 µs per loop

In [107]: %timeit c = np.array([b,]*100).transpose()
100 loops, best of 3: 5.56 ms per loop

about 15 times faster using broadcast

The V8 debugger released as part of the Google Chrome Developer Tools can be used to debug Node.js scripts. A detailed explanation of how this works can be found in the Node.js GitHub wiki.

Create a zip folder in PHP.

Zip create method

   public function zip_creation($source, $destination){
    $dir = opendir($source);
    $result = ($dir === false ? false : true);

    if ($result !== false) {

        
        $rootPath = realpath($source);
         
        // Initialize archive object
        $zip = new ZipArchive();
        $zipfilename = $destination.".zip";
        $zip->open($zipfilename, ZipArchive::CREATE | ZipArchive::OVERWRITE );
         
        // Create recursive directory iterator
        /** @var SplFileInfo[] $files */
        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($rootPath), RecursiveIteratorIterator::LEAVES_ONLY);
         
        foreach ($files as $name => $file)
        {
            // Skip directories (they would be added automatically)
            if (!$file->isDir())
            {
                // Get real and relative path for current file
                $filePath = $file->getRealPath();
                $relativePath = substr($filePath, strlen($rootPath) + 1);
         
                // Add current file to archive
                $zip->addFile($filePath, $relativePath);
            }
        }
         
        // Zip archive will be created only after closing object
        $zip->close();
        
        return TRUE;
    } else {
        return FALSE;
    }


}

Call the zip method

$source = $source_directory;
$destination = $destination_directory;
$zipcreation = $this->zip_creation($source, $destination);

I was struggling for a while with this problem. Some of the solutions worked however some of my views where still being pushed up while others weren't... So it didn't completely solve my problem. In the end, what did the job was adding the following line of code to my manifest in the activity tag...

android:windowSoftInputMode="stateHidden|adjustPan|adjustResize"

Good luck

You can simply make your action result as NoContentResult on controller

public NoContentResult UploadFile([FromForm] VwModel model)
    {
       return new NoContentResult();
    } 

This is an old post but still a problem within the Chrome dev tools. I find the best way to check mobile source locally is to open the site locally in Xcode's iOS Simulator. Then from there you open the Safari browser and enable dev tools, if you have not already done this (go to preferences -> advanced -> show develop menu in menu bar). Now you will see the develop option in the main menu and can go to develop -> iOS Simulator -> and the page you have open in Xcode's iOS Simulator will be there. Once you click on it, it will open the web inspector and you can edit as you would normally in the browser dev tools.

I'm afraid this solution will only work on a Mac though as it uses Xcode.

In case you are looking for a cut and paste method that creates and writes to a file, here's one I wrote that just takes a String input. Remove 'true' from PrintWriter if you want to overwrite the file each time.

private static final String newLine = System.getProperty("line.separator");

private synchronized void writeToFile(String msg)  {
    String fileName = "c:\\TEMP\\runOutput.txt";
    PrintWriter printWriter = null;
    File file = new File(fileName);
    try {
        if (!file.exists()) file.createNewFile();
        printWriter = new PrintWriter(new FileOutputStream(fileName, true));
        printWriter.write(newLine + msg);
    } catch (IOException ioex) {
        ioex.printStackTrace();
    } finally {
        if (printWriter != null) {
            printWriter.flush();
            printWriter.close();
        }
    }
}

With FluidXML you can generate and store an XML document very easily.

$doc = fluidxml();

$doc->add('Album', true)
        ->add('Track', 'Track Title');

$doc->save('album.xml');

Loading a document from a file is equally simple.

$doc = fluidify('album.xml');

$doc->query('//Track')
        ->attr('id', 123);

As of Java 8 you can simply do:

Instant.now().toString();

From the java.time.Instant docs:

now

---

public static Instant now()

Obtains the current instant from the system clock.

This will query the system UTC clock to obtain the current instant.

toString

---

public String toString()

A string representation of this instant using ISO-8601 representation.

The format used is the same as DateTimeFormatter.ISO_INSTANT.

var window = new MyWindow();

for center of the screen use:

window.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterScreen;

for center of the parent window use:

window.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterOwner;

You can find the list of duplicate names using the following aggregate pipeline:

• Group all the records having similar name.
• Match those groups having records greater than 1.
• Then group again to project all the duplicate names as an array.

The Code:

db.collection.aggregate([
{$group:{"_id":"$name","name":{$first:"$name"},"count":{$sum:1}}},
{$match:{"count":{$gt:1}}},
{$project:{"name":1,"_id":0}},
{$group:{"_id":null,"duplicateNames":{$push:"$name"}}},
{$project:{"_id":0,"duplicateNames":1}}
])

o/p:

{ "duplicateNames" : [ "ksqn291", "ksqn29123213Test" ] }

I solved my problem using:

top -n1 -b | grep "proccess name"

in this case: -n is used to set how many times top will what proccess
and -b is used to show all pids

it's prevents errors like : top: pid limit (20) exceeded

An alternate method that limits the scope of the lambda rather than giving it access to the whole this is to pass in a local reference to the member variable, e.g.

auto& localGrid = grid;
int i;
for_each(groups.cbegin(),groups.cend(),[localGrid,&i](pair<int,set<int>> group){
            i++;
            cout<<i<<endl;
   });

Solution for this issue is:

1. Create another connection manager for your excel or flat files else you just have to pass variable values in connection string:

2. Right Click on Connection Manager>>properties>>Expression >>Select "ConnectionString" from drop down and pass the input variable like path , filename ..

This is a very round-about way of doing it but if you want to make a histogram where you already know the bin values but dont have the source data, you can use the np.random.randint function to generate the correct number of values within the range of each bin for the hist function to graph, for example:

import numpy as np
import matplotlib.pyplot as plt

data = [np.random.randint(0, 9, *desired y value*), np.random.randint(10, 19, *desired y value*), etc..]
plt.hist(data, histtype='stepfilled', bins=[0, 10, etc..])

as for labels you can align x ticks with bins to get something like this:

#The following will align labels to the center of each bar with bin intervals of 10
plt.xticks([5, 15, etc.. ], ['Label 1', 'Label 2', etc.. ])
